|
|
* common.c,dwarfdump.c,tag_attr.c,tag_tree.c:
|
|
Update version strings.
|
|
2016-11-24 David Anderson
|
|
* Makefile.in: Clean *~
|
|
2016-11-22 David Anderson
|
|
* print_abbrevs.c: Some -k abbrev warnings did not make it clear that
|
|
they were checking against a heuristic sanity-check value
|
|
for the maximum number of attributes, not a genuine
|
|
maximum.
|
|
2016-11-22 David Anderson
|
|
* tag_attr.c: Remove bogus blank line with trailing spaces.
|
|
2016-11-11 David Anderson
|
|
* print_frames.c: Apply fix to local_dwarf_decode_s_leb128_chk so
|
|
it matches libdwarf dwarf_leb.c. A fix for certain bit
|
|
pattern provoking undefined behavior in C..
|
|
2016-11-01 David Anderson
|
|
* tag_attr.c,tag_common.h,tag_attr_ext.list: Adding
|
|
Ada GNAT gcc attributes DW_AT_GNU_numerator,
|
|
DW_AT_GNU_denominator, DW_AT_GNU_bias in the extended
|
|
table for checking.
|
|
2016-10-21 David Anderson
|
|
* common.c,dwarfdump.c,tag_attr.c,tag_tree.c: Update
|
|
version strings.
|
|
2016-09-30 David Anderson
|
|
* configure.in: Add additional -fsanitize tests to
|
|
--enable-sanitize option.
|
|
* configure: Regenerated.
|
|
* print_die.c: Ensure << applied to unsigned
|
|
to avoid undefined operation. We were getting
|
|
officially undefined behavior.
|
|
* tag_attr_ext.list: Removed trailing whitespace from
|
|
two lines.
|
|
2016-09-30 David Anderson
|
|
* makename.c: The unused static function value_hashfunc()
|
|
has been removed.
|
|
* tag_attr.c, tag_tree.c: Changed (1<<bit) to
|
|
(((unsigned)1)<<bit) to avoid a runtime error
|
|
(during dwardump build) about the left shift.
|
|
2016-09-27 David Anderson
|
|
* esb.c: Deleted file-static variable that was only
|
|
used for a test. No longer needed.
|
|
2016-09-27 David Anderson
|
|
* print_die.c: Changed the name of experimental
|
|
loclist operators from LLE to LLEX
|
|
as these are in use for certain DWARF4 loclist
|
|
providers. The DWARF5 LLE don't use the same
|
|
numberic values as the experimental ones.
|
|
2016-09-23 David Anderson
|
|
* Makefile.in: A mistake here meant every compile
|
|
rebuilds all of dwarfdump even with a trivial change.
|
|
Fixed so now trivial changes just rebuild a minimum.
|
|
The dependencies here remain incomplete: if you change
|
|
a data structure you must 'make clean' and recompile
|
|
everything in dwarfdump.
|
|
2016-09-22 David Anderson
|
|
* dwarfdump.c,print_die.c,print_frames.c,print_gdbindex.c:
|
|
In case of error, dwarf_dealloc the error once it
|
|
has been printed. Avoiding a small memory leak.
|
|
2016-09-21 David Anderson
|
|
* configure.in: Supports --enable-sanitize which
|
|
sets dwfsanitize so build uses -fsanitize=address .
|
|
* configure: Regenerated.
|
|
* Makefile.in: Now uses dwfsanitize (when set)
|
|
during builds. Added dwarf_tsearchbal.c to the makename
|
|
build so dwarf_tsearchbal.o is available for tag_tree_build
|
|
and tag_attr _buildprograms at build time.
|
|
* dwarfdump.c: Moved all static struct esb_s variables
|
|
to the top level and ensure they are destructed on
|
|
normal exit. Destruct all static makename strings, abbrev
|
|
data, sanitized strings, and ranges strings.
|
|
Now all allocated memory is freed before a normal exit.
|
|
* esb.c: Added {} and commentary for clarity.
|
|
esb_destructor now a bit more careful (redundantly but
|
|
helpful for a reader).
|
|
* globals.h: Declared destructors allowing access to
|
|
static data allocated in certain source files.
|
|
Fixed the selftest code.
|
|
* macrocheck.c: Correct selftest code.
|
|
* makename.c: Now uses dwarf_tsearch to keep a record of
|
|
strings it allocates and avoids duplicating strings.
|
|
A destructor gives a way to free the allocated memory.
|
|
* makename.h: Added declaration of makename_destructor().
|
|
* print_abbrevs.c: Implemented destruct_abbrev_array() to
|
|
clean up a static array.
|
|
* print_die.c: Tidied up declaration/constructor pairs
|
|
so it's easier to see that all declarations have a constructor
|
|
call.
|
|
* print_lines.c: Tidied up declaration/constructor pair
|
|
so it's easier to see that the constructor is called.
|
|
* print_locs.c: Tidied up declaration/constructor pair
|
|
so it's easier to see that the constructor is called.
|
|
* print_ranges.c: Implemented ranges_esb_string_destructor()
|
|
to destruct local static esb string at normal dwarfdump exit.
|
|
* sanitized.c: Implemented sanitized_string_destructor()
|
|
to destruct local static esb string at normal dwarfdump exit.
|
|
* strstrnocase.c: Code could do *ct past end of string.
|
|
Fixed to avoid that.
|
|
2016-09-15 David Anderson
|
|
* configure.in: Added check for unistd.h.
|
|
* configure: regenerated.
|
|
* dwarfdump.c,tag_attr.c,tag_tree.c: Add #ifdef HAVE_UNISTD_H
|
|
for unistd.h include.
|
|
2016-09-15 David Anderson
|
|
* tag_tree.c: Two local variables had no initializer.
|
|
Though adding the initializers is logically unnecessary
|
|
it is the standard way to code in libdwarf/dwarfdump.
|
|
2016-09-13 David Anderson
|
|
* print_die.c: Shortened the printing of DW_AT_discr_list
|
|
to improve readability.
|
|
2016-09-09 David Anderson
|
|
* tag_attr.c,tag_tree.c: Further improvements to ensure we do not run
|
|
off the ends of rows or columns.
|
|
New commentary on array contents of generated arrays.
|
|
* tag_tree.c: Further improvements to ensure we do not run
|
|
off the ends of rows or columns.
|
|
* tag_attr_ext.list: Removed accidental extra characters.
|
|
Added DW_AT_GNU_dwo_id to dW_TAG_compile_unit.
|
|
* tag_common.c: The static declaration of the internal tables
|
|
used to build table source code was not checked so there
|
|
were some array entries stepped on. fixed.
|
|
* tag_common.h: Added commentary. Made the build-time-only
|
|
static array declaration size macros more explicit.
|
|
2016-09-09 David Anderson
|
|
* print_die.c: Fixed compiler warnings introduced
|
|
in previous commit.
|
|
2016-09-08 David Anderson
|
|
* print_die.c: Now we use the new dwarf_discr_list()
|
|
to read DW_AT_discr_list correctly and print it.
|
|
* tag_attr.c,tag_tree.c: Now we check for too-small and too-large
|
|
array sizes and stop the build in case of error.
|
|
* tag_common.h: Now the static array sizes match
|
|
the lists.
|
|
2016-06-13 David Anderson
|
|
* sanitized.c: Added static keyword to declaration of
|
|
no_questionable_chars().
|
|
* print_frames.c: Added a warning about a useless
|
|
frame operator (if such appears, only checkedwith -f -vvv).
|
|
Ensure we print rows generated even if a pointless last row
|
|
(a break becomes continue).
|
|
* common.c,dwarfdump.c,tag_attr.c,tag_tree.c,gennames.c:
|
|
Update version string.
|
|
2016-06-12 David Anderson
|
|
* common.c,dwarfdump.c,tag_attr.c,tag_tree.c,gennames.c:
|
|
Update version string.
|
|
2016-06-12 David Anderson
|
|
* print_frames.c: Using a new frame interface to reduce
|
|
dwarfdump runtime on frame printing by 10 percent.
|
|
2016-06-10 David Anderson
|
|
* print_frames.c: Added commentary as the previous comment
|
|
about printing CFA and other registers having a 'duplicate row'
|
|
was a bit terse.
|
|
2016-06-08 David Anderson
|
|
* sanitized.c: Remove trailing whitespace.
|
|
2016-06-08 David Anderson
|
|
* common.c,dwarfdump.c,tag_attr.c,tag_tree.c:
|
|
Update version string.
|
|
* sanitized.c: Only fix strings that have bad
|
|
characters in them. This improves dwarfdump performance.
|
|
2016-06-01 David Anderson
|
|
* dwarfdump.c, common.c: Update version string.
|
|
Use DW_VERSION_DATE_STR instead of DWARFDUMP_VERSION
|
|
* tag_attr.c, tag_tree.c: Use DW_VERSION_DATE_STR instead
|
|
of __DATE__ __TIME__
|
|
* Makefile.in: Tweaked for debian build compatibility.
|
|
2016-05-22 David Anderson
|
|
* dwarfdump.c, common.c: Update version string.
|
|
2016-05-20 David Anderson
|
|
* print_frames.c: One test for erroneous length was
|
|
incorrectly coded, leading to possible crash when encountering
|
|
erroneous frame information.
|
|
2016-05-19 David Anderson
|
|
* configure.in: Does a better job reporting configure actions.
|
|
* configure: Regenerated
|
|
* dwarfdump.1: Fixed spelling errors and moved ./dwarfdump.conf
|
|
right one space to get the dot off column 1.
|
|
2016-05-18 David Anderson
|
|
* print_die.c: Fix typo in error message.
|
|
* print_frames.c: Do additional checks for incorrect data
|
|
when printing frame instructions to avoid dwarfdump crash..
|
|
2016-05-12 David Anderson
|
|
* print_abbrevs.c,print_aranges.c,print_frames.c,print_sections.c:
|
|
Removed trailing whitespace. Fixed indentation.
|
|
* tag_attr.c,tag_tree.c: Ensure calls to libdwarf interfaces
|
|
in these build-time tools check the status returned.
|
|
2016-05-10 David Anderson
|
|
* print_aranges.c: Minor commentary change and
|
|
rearranging lines for clarity.
|
|
* print_die.c: formwith->form with
|
|
in an error message.
|
|
* print_frames.c: Now checks for bogus expression block
|
|
lengths and bogus LEB values. LEB reading functions
|
|
now here and static functions.
|
|
* print_sections.c: Moved leb reading functions to print_frames.c
|
|
2016-05-07 David Anderson
|
|
* dwarfdump.c, common.c: Update version string.
|
|
* print_frames.c: For local variable added
|
|
initialization-at-definition.
|
|
2016-05-06 David Anderson
|
|
* sanitized.c: Fixed trailing whitespace and
|
|
added 'static' to local function definition.
|
|
2016-05-05 David Anderson
|
|
* Makefile.in: Added sanitized.o to objects to build.
|
|
* dwarfdump.1: Document '-x nosanitizestrings'.
|
|
* dwarfdump.c: Set internal flag based on '-x nosanitizestrings'.
|
|
* globals.h: add extern for the flag no_sanitize_string_garbage
|
|
and the sanitized() interface.
|
|
* print_die.c,print_frames.c,print_lines.c,
|
|
print_macro.c, print_macros.c : Call sanitized() on some strings.
|
|
* sanitized.c: Changes control characters int output to %xx
|
|
uri-style (by default). See '-x nosanitizestrings'.
|
|
2016-05-03 David Anderson
|
|
* dwarfdump.c: revise print_error_maybe_continue() to
|
|
print additional useful data.
|
|
* print_die.c: If dwarf_srcfiles() gets DW_DLV_NO_ENTRY
|
|
do not print a warning. Normal to have no DW_AT_stmt_list.
|
|
* print_lines.c: Fix column header 'row' changed to 'lno'.
|
|
Refine a CHECK message to say a DW_LNE_end_sequence
|
|
does not exactly match function high address. It is not
|
|
an error, just something about how the code was emitted.
|
|
2016-04-30 David Anderson
|
|
* dwarfdump.c, common.c: Update version string.
|
|
2016-04-27 David Anderson
|
|
* dwarfdump.c, common.c: Update version string.
|
|
2016-04-27 David Anderson
|
|
* dwarfdump.c: Update version string.
|
|
Remove a field from printf on error as that duplicates
|
|
the error number in the error string.
|
|
2016-04-25 David Anderson
|
|
* esb.c, dwarfdump.c: Fix a couple indent mistakes.
|
|
2016-04-25 David Anderson
|
|
* esb.h, esb.c: The typedef for 'string' is now gone, it
|
|
was never helpful..
|
|
* dwarfdump.c: Remove 'string' use.
|
|
* dwgetopt.c: Moved test-only function to getopttest.c.
|
|
Added (void) argument to a the functions with no arguments.
|
|
* getopttest.c: Repaired failures to to renaming
|
|
to dwoptind etc and added the test-only
|
|
function from dwgetopt.c
|
|
* globals.h: Removed 'string' typedef.
|
|
* print_die.c,print_frames.c, print_lines.c, print_strings.c,
|
|
tag_attr.c, tag_tree.c: Removed use of 'string' type, use
|
|
plain old char*.
|
|
2016-04-21 Carlos Alberto Enciso
|
|
Printing using the 'esb' module was broken. It seems to work
|
|
because the default internal buffer size (240), was big enough
|
|
to receive the resulting output.
|
|
|
|
* esb.c, esb.h: Missing prefix 'esb' for 'allocate_more'.
|
|
Initial buffer size reduced to 16.
|
|
New function 'esb_open_null_device': open 'null' device.
|
|
New function 'esb_close_null_device': close 'null' device.
|
|
New function 'esb_allocate_more_if_needed': allocate more
|
|
space if required, leaving the contents unchanged, so the
|
|
caller, does not need to worry about it.
|
|
There are 2 cases:
|
|
Windows: use the 'null' device to get the required space
|
|
UNIX: use a big buffer (512). But if the result is bigger,
|
|
the original problem will be shown.
|
|
The function 'esb_append_printf_ap', now takes care of
|
|
increasing the buffer if needed.
|
|
|
|
* dwarfdump.c: In the case of windows, open and close the 'null'
|
|
device, in order to setup the esb module.
|
|
2016-04-21 Carlos Alberto Enciso
|
|
* globals.h: Do not define 'string' for a C++ build; it clashes with
|
|
the 'std::string'.
|
|
* print_die.c: Minor typo error.
|
|
2016-04-21 Carlos Alberto Enciso
|
|
* For a WINDOWS version, display the 32/64 bits configuration.
|
|
2016-04-21 Carlos Alberto Enciso
|
|
* Use the _WIN32 macro to identify a WINDOWS specific code.
|
|
2016-03-17 David Anderson
|
|
* print_die.c(print_one_die_section): One dieprint_cu_goffset
|
|
Dwarf_Unsigned->Dwarf_Off.
|
|
2016-03-12 David Anderson
|
|
* print_abbrevs.c(print_abbrevs): Printed output of an abbrev with code
|
|
and tag but no attributes was simply wrong. Now fixed.
|
|
Now avoids printing children flag on a null abbrev (a NUL byte
|
|
meaning no abbrev is there at all, ending a list of abbrevs).
|
|
* print_die.c: it was difficult, even with -G -v, to identify
|
|
the actual offset (in .debug_abbrev) of the abbreviations.
|
|
Now -i -G -v gives a bit more data on abbreviations.
|
|
2016-03-09 David Anderson
|
|
* dwarfdump.c,globals.h,print_aranges.c,print_die.c,print_frames.c,
|
|
print_lines.c,print_macro.c,print_pubnames.c:
|
|
Remove the global dieprint_cu_offset, use local vars and pass around instead.
|
|
Ensure the traverse() logic when checking type references do not evaluate
|
|
references to other sections. Many argument lists got an additional argument or two.
|
|
2016-03-07 David Anderson
|
|
* dwarfdump.c: Update version string. Added CU_low_address so
|
|
CU_base_address is properly used only for the DWARF
|
|
CU 'base address' notion. Print CU_low_address in PRINT_CU_INFO().
|
|
* common.c: Update version string
|
|
* globals.h: New macro DROP_ERROR_INSTANCE(d,r,e) improves consistency
|
|
where we need to drop a Dwarf_Error instance.
|
|
* print_die.c: Support for CU_low_address. Use DROP_ERROR_INSTANCE
|
|
where appropriate.
|
|
* print_frames.c: Use DROP_ERROR_INSTANCE
|
|
where appropriate.
|
|
2016-03-03 Carlos Alberto-Enciso
|
|
* dwarfdump.c: Missing '_' just for consistency.
|
|
Print any harmless errors only the required in command line
|
|
* globals.h: Unused declaration.
|
|
* print_die.c: When displaying a DW_AT_type offset error, uses the standard
|
|
0xdddddddd format. Wrap to 80 columns, a long line.
|
|
2016-02-17 Carlos Alberto-Enciso
|
|
* dwarfdump/tag_attr_ext.list,dwarfdump/tag_common.h,
|
|
dwarfdump/tag_tree_ext.list: Tighten up the list limits
|
|
and add commentary about the list limits.
|
|
2016-02-14 DavidAnderson
|
|
* dwarfdump.c,common.c: Updated version strings.
|
|
* print_die.c,print_strings.c: fixed indent errors.
|
|
2016-02-14 Carlos Alberto-Enciso
|
|
* tag_attr_ext.list, tag_tree_ext.list: Adding
|
|
DW_TAG_GNU_template_parameter_pack,DW_TAG_GNU_formal_parameter_pack.
|
|
* tag_tree.c: Printed wrong name from tag-tree table in
|
|
a comment.
|
|
* tag_common.h: Ext tag table rows count was higher than needed.
|
|
Ext attr table rows increased to 11.
|
|
2016-02-13 David Anderson
|
|
* dwarfdump.c,globals.h,print_aranges.c,print_die.c,
|
|
print_frames.c,print_lines.c,print_locs.c,print_macro.c,
|
|
print_pubnames.c,print_reloc.ckprint_static_funcs.c,
|
|
print_static_vars.c,print_strings.c,print_types.c,
|
|
print_weaknames.c: Removed global Dwarf_Error err
|
|
and provided local Dwarf_Error as needed.
|
|
2016-02-13 David Anderson
|
|
* configure.in: Add -Wshadow to --enable-shared. Add else and
|
|
cross-compile [] to the AC_TRY_RUN
|
|
* configure: Regenerate.
|
|
* dwarf_tsearchbal.c: Delete shadowed variable p, we use
|
|
the original instead.
|
|
* dwarfdump.c: Rename variables to avoid confusing
|
|
duplicated names (found by -Wshadow). #if 0 the
|
|
unused function old_get_cu_name(), which should get deleted.
|
|
* globals.h: Fixed prototypes, #if 0 prototype of
|
|
the unused function old_get_cu_name().
|
|
* print_abbrevs.c, print_aranges.c,print_debugfission.c,
|
|
print_die.c,print_frames.c, print_gdbindex.c, print_lines.c,
|
|
print_pubnames.c, print_ranges.c, print_sections.c,
|
|
tag_attr.c, tag_tree.c: Add local Dwarf_Error and
|
|
rename variables to avoid shadowing confusion.
|
|
2016-02-10 David Anderson
|
|
* globals.h: Change enum val from std to singledw5.
|
|
Some compilation environments reserve 'std'.
|
|
* dwarfdump.c,print_lines.c: Use the new spelling.
|
|
2016-02-10 David Anderson
|
|
* common.c,dwarfdump.c: Update version string.
|
|
2016-02-07 David Anderson
|
|
* common.c,dwarfdump.c: Update version string.
|
|
2016-02-06 David Anderson
|
|
* print_die.c,tag_attr.c,tag_tree.c: Remove trailing whitespace.
|
|
2016-02-06 David Anderson
|
|
* warningcontrol.h: Defines UNUSEDARG macro as needed.
|
|
* common.c,dwarf_tsearchbal.c,dwarfdump.c,globals.h,
|
|
macrocheck.c: Now use UNUSEDARG macro so known-unused
|
|
args do not cause spurious warnings.
|
|
* configure.in: Sets HAVE_UNUSED_ATTRIBUTE if the compiler
|
|
in use supports __attribute ((unused)). So we can have
|
|
lots of warnings turned on without seeing the warnings
|
|
we wish to ignore for now.
|
|
* configure,config.h.in: Regenerated.
|
|
2016-02-06 David Anderson
|
|
* print_frames.c: Was printing cie index, not fde index,
|
|
in the fde output. Now prints more sensibly.
|
|
Now tests do_print_dwarf, the flag it should have been using,
|
|
to decide whether to print.
|
|
2016-02-02 David Anderson
|
|
* dwarfdump.c: Get section sizes so we can do a better
|
|
sanity check on ofsets (ie, call dwarf_get_section_max_offsets_c()).
|
|
Check DWARF2 macros for sanity just as we do DWARF5
|
|
macros. Read DWARF2 macros per-cu, not as a standalone
|
|
section. Add global data section_high_offsets_global,
|
|
a struct with all known section sizes.
|
|
* macrocheck.c: New section size argument for more complete
|
|
size analysis.
|
|
* globals.h: Declarations for section_high_offsets_global.
|
|
* macrocheck.h: Update prototype of print_macro_statistics().
|
|
* print_die.c: Drop section-as-a-whole macro reporting for
|
|
macinfo in favor of reporting per CU.
|
|
* print_macros.c: Allow for print and check runs (not both
|
|
at once).
|
|
2016-01-28 David Anderson
|
|
* dwarfdump.c,common.c: Update version string.

|
* print_die.c: Changed the most frequent global die
|
|
offset values to print as GOFF=0x...
|
|
for uniformity with -G and space saving from the
|
|
string 'global die offset'.
|
|
2016-01-27 David Anderson
|
|
* print_die.c: Added a helpertree find call on typedieoffset
|
|
which is really a better check for known signed/unsigned.
|
|
2016-01-26 David Anderson
|
|
* dwarfdump.c,common.c: Update version string.
|
|
2016-01-26 David Anderson
|
|
* Makefile.in: Added helpertree.h, and .c.
|
|
* dwarfdump.c: Added include helpertree.h
|
|
* print_die.c: Now attempts (harder) to
|
|
figure out if a constant is really signed or insigned
|
|
when printing it. Fixes annoyance with printing attributes
|
|
longer than 27 characters.
|
|
Unifies a number of printf-style calls into functions, reducing
|
|
the number of statically visible calls to sprintf.
|
|
Attempts to remember whether some things are explicitly
|
|
typed as signed or unsigned.
|
|
* helpertree.h, helpertree.c: New. Simple use of tsearch
|
|
to memo-ize signedness.
|
|

|
|
* macrocheck.c: Remove trailing whitespace.
|
|
* print_lines.c: Only print line context record
|
|
if we do_print_dwarf is non-zero. The directory index
|
|
was printing as 0 in the line_context record. Was a typo
|
|
in the printf, now fixed.
|
|
2016-01-20
|
|
* configure.in: Now --enable-wall adds -Wdeclaration-after-statement
|
|
etc.
|
|
* configure: Regenerated.
|
|
* dwarfdump.c: Now all functions have visible prototypes, no ().
|
|
* dwconf.c: Now local func declared static.
|
|
* dwgetopt.c: Added include dwgetopt.h. Unused function
|
|
#if 0 so invisible.
|
|
* globals.h: Now all functions have prototypes, no ().
|
|
* macrocheck.c: Removed unused locals. Fixed a
|
|
dwarf_twalk call to *tree (not just tree).
|
|
* naming.c: Added include naming.h.
|
|
* print_gdbindex.c: Made local function static.
|
|
* tag_attr.c,tag_common.c: Made local function static.
|
|
2016-01-19 David Anderson
|
|
* dwarf_tsearchbal.c: Deleted the unused function rotatex().
|
|
* dwarfdump.c: Remove duplicate trailing ;
|
|
* esb.c(esb_append): Straighten out the logic
|
|
and avoid doing append if the to-be-appended
|
|
string is empty.
|
|
* globals.h Add ifdef __cplusplus for extern "C".
|
|
* esb.h,naming.h: Idempotent #ifndef and __cplusplus extern "C" added.
|
|
* print_frames.c: Ensure local var starts at zero.
|
|
Move statement to below declarations.
|
|

|
|
* print_frames.c: Fix trailing whitespace and indentation.
|
|
2016-01-19 David Anderson
|
|
* print_die.c,tag_tree.c: Change statement ;; by removing
|
|
second semicolon.
|
|
2016-01-17 David Anderson
|
|
* common.c: Update version string
|
|
* dwarfdump.c: Made reset_overall_CU_error_data() a global.
|
|
We now try to show CU name etc on case there is an error
|
|
reading frame data. Update version strin.
|
|
Added DEBUG_FRAME DEBUG_FRAME_EH to the PRINT_CU_INFO() tests.
|
|
New function: load_CU_error_data().
|
|
* print_frames.c: Now uses a local Dwarf_Error
|
|
in a few places (CU names for frames) instead
|
|
of the global 'err' so we do not get the errors
|
|
mixed up.
|
|
We now try to show CU name etc on case there is an error
|
|
reading frame data.
|
|
2016-01-14 David Anderson
|
|
* common.c: Update version string.
|
|
* dwarfdump.c: Update version string. Include macrocheck.h.
|
|
Delete one accidental blank line.
|
|
* dwarf_tsearchbal.c: Added comment about compiler warning.
|
|
* dwarf_macrocheck.c: Added missing return statement.
|
|
Removed trailing whitespace. Fixed broken qsort_compare()
|
|
* macrocheck.h: Fixed trailing whitespace.
|
|
* print_abbrevs.c: Generalized an attribute count warning
|
|
a bit (see GENERAL_MAX_ATTRIB_COUNT). Fixed the code
|
|
handling the abbrev_array to be correct and a bit simpler.
|
|
Added new abbreviations tests.
|
|
* print_die.c: Include macrocheck.h. Fix trailing whitespace.
|
|
2016-01-12 David Anderson
|
|
* common.c: Update version string.
|
|
* dwarfdump.c: Update version string.
|
|
* print_abbrevs.c: If an abbreviation number is a bit
|
|
goofy, accomodate it so we do not write to
|
|
memory we did not allocate. It will
|
|
be caught a bit later in the run as an invalid DIE
|
|
or abbreviation.
|
|
* print_die.c: When we switch sections inside a DIE print
|
|
save and restore current_section_id to get the best
|
|
reporting on errors/checks.
|
|
2016-01-12 David Anderson
|
|
* common.c,dwarfdump.c: Update version string.
|
|
2016-01-12 David Anderson
|
|
* Makefile.in: Adding macrocheck.h, and .c. Adding
|
|
selftest of macrocheck.c.
|
|
* dwarfdump.c: Now handles imported DWARF5 macros
|
|
and adds support for -kw for macro section checking.
|
|
* globals.h: Adding check_macros flag and macro_check_tree declaration
|
|
and print_macros_5style_this_cu() declaration..
|
|
* print_die.c: Now prints imported macros using
|
|
print_macros_5style_this_cu().
|
|
* print_macro.c: Now deals with imported macro units using
|
|
macrocheck.c and .h. Fixed bug for DW_MACRO_define/undef
|
|
where we did improper string validity check.
