end up not using it.
(UNWIND_TBL_32BIT): New macro.
(struct unwind_header): Rename "unknown1" member to "header_version".
(tdep_find_proc_info) [HAVE_DLMODINFO]: Don't forget to initialize di.gp.
Check unwind-header version and format.
(Logical change 1.87)
Rename Gmk_cursor to mk_Gcursor, Lmk_cursor to mk_Lcursor so to avoid
scripts/make-L-files overwriting the (handcrafted) local version.
(EXTRA_DIST): Mention libunwind_la_SOURCES_os_hpux.
(Logical change 1.87)
Update code to work both for UNW_LOCAL_ONLY-version of the cursor and the
generic version of the cursor.
(ia64_install_cursor): New macro.
}(Logical change 1.85)
Update code to work both for UNW_LOCAL_ONLY-version of the cursor and the
generic version of the cursor.
(ia64_install_cursor): New macro.
2003/04/23 11:25:31-07:00 mostang.com!davidm
Rename: src/ia64/_Uia64_install_cursor.S -> src/ia64/Ginstall_cursor.S
(Logical change 1.85)
and Linstall_cursor.S.
(Gmk_cursor_i_ia64_SOURCES): Rename from mk_cursor_i_ia64_SOURCES.
(Lmk_cursor_i_ia64_SOURCES): New mcro.
(Gcursor_i.h): Rename rule from cursor_i.h.
(Lcursor_i.h): New rule.
(noinst_PROGRAMS): Rename mk_cursor_i-ia64 to Gmk_cursor_i-ia64 and add
Lmk_cursor_i-ia64.
(BUILT_SOURCES): Ditto.
(Logical change 1.85)
more or less unchanged, but for the generic version, the save-location has been
expanded from a single word to two words. This is needed to accommodate 32-bit
targets and targets which require accessing the ucontext_t structure via uc_access(3).
Overall, this should be like a big no-op for Linux (apart from slowing down
the generic case a bit). However, at the moment, unw_resume() has not been updated
for the generic case (UNW_LOCAL_ONLY works fine though).
BKrev: 3ea62b2bm3Pz-s7tNlN5IA-1ENWKWw
(struct_offset): Delete.
(IA64_LOC_REG): New macro (replaces IA64_LOC() for registers).
(IA64_LOC_ADDR): New macro (replaces IA64_LOC() for addresses).
(IA64_LOC_UC_ADDR): New macro.
(IA64_NULL_LOC): Ditto.
(IA64_IS_NULL_LOC): Ditto.
(IA64_IS_UC_LOC): Ditto.
(struct ia64_state_record): Replace is_signal_frame bit with abi_marker.
(ia64_strloc): New declaration.
(rbs_switch): Change from UNW_ARCH_OBJ() to UNW_OBJ().
(rbs_find_stacked): Ditto.
(rbs_cover_and_flush): Ditto.
(rbs_get_rnat_loc): New inline function.
(rbs_loc): Ditto.
(Logical change 1.84)
Adjust for renaming of Linux sigcontext offset macros.
(check_rbs_switch): Handle Linux-case only if abi_marker==ABI_MARKER_LINUX_SIGTRAMP.
(update_frame_state): For cursor's with a non-zero abi_marker, do special
Linux or HP-UX sigtramp handling as appropriate.
Clear abi_marker instead of is_signal_frame.
(Logical change 1.84)
(emit_nat_info): For registers saved in a general-register, use IA64_INSN_SET_REG
instead of IA64_INSN_SET.
Set insn.dst to register number, instead of unw.preg_index[i].
(compile_reg): Set val directly to register number, instead of unw.preg_index[i].
Use IA64_INSN_INC_PSP instead of IA64_INSN_ADD to pop a fixed stack frame.
(build_script): Handle signal-frames by directly copying abi_marker, rather than
emitting an IA64_INSN_SET instruction.
(run_script): Copy abi_marker into cursor. Rather than updating a word, update
a save-location. Only exceptions are IA64_INSN_INC_PSP and
IA64_INSN_LOAD_PSP.
(Logical change 1.84)
(ia64_loc_t): New type. For UNW_LOCAL_ONLY, it's a single word, as before.
For the generic case, it's a 2-word structure. This provides enough
space to encode all necessary info both for 32-bit targets (which require
only 4-byte aligned addresses) and for targets which are limited to
accessing ucontext_t values via uc_access(3).
(ABI_MARKER_LINUX_SIGTRAMP): New macro.
(ABI_MARKER_HP_UX_SIGTRAMP): New macro.
(struct cursor): Consolidate bsp_loc, bspstore_loc, pfs_loc, rnat_loc, ip_loc,
pri_unat_loc, unat_loc, pr_loc, lc_loc, fpsr_loc, r4-r7_loc,
b1-b5_loc, f2-f7_loc, and fr_loc[] into loc[] array. Note that
there is now a separate PSP-loc (loc[IA64_REG_PSP]) in addition
to the cached psp value.
Rename sigcontext_loc to sigcontext_addr.
Remove is_signal_frame memeber and add abi_marker member instead.
Change type of rbs_area[].rnat_loc to ia64_loc_t.
(struct ia64_global_unwind_state): Remove preg_index[] array.
(Logical change 1.84)
Mask out only the least-significant 2 bits (rather than the least significant
3 bits).
