(access_reg) [HAVE_SYS_UC_ACCESS_H]: Sanitize and simplify this routine. Turns out
uc_access(3) works pretty much the way we need it, the only problem is that
the unwind info for getcontext() seems to be missing as of HP-UX 11.22.
(ia64_uc_access_reg): New function.
(ia64_uc_access_fpreg): Ditto.
(ia64_local_addr_space_init): Initialize "abi" member of local address space based
on the platform we're compiling on.
(Logical change 1.87)
have an empty file here, as otherwise we won't get a valid program.

Rename: src/ia64/Lmk_cursor_i-ia64.c -> src/ia64/mk_Lcursor_i-ia64.c
(Logical change 1.87)
(remote_install_cursor): Enable the short-cut for Linux only. Since HP-UX uses
an opaque data-structure for ucontext_t, we can't play the same trick
there. Fix two typos: "> 0" -> ">= 0".
(unw_resume): Handle non-UNW_LOCAL_ONLY case simp;u bu calling
remote_install_cursor().
(Logical change 1.87)
support for HP-UX.
(access_nat): Check for uc-location and pass it on to ia64_put()/ia64_get() if
it is. Handle NaT-bit-saved-in-scratch-register only for Linux.
(ia64_access_reg): Change dprintf() into debug() statement.
(ia64_access_fpreg): Move fph-partition initialization code to ia64_scratch_loc().
Change dprintf() into debug() statement.
(Logical change 1.87)
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)
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)
(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)
Mask out only the least-significant 2 bits (rather than the least significant
3 bits).

Rename: src/ia64/_Uia64_install_context.S -> src/ia64/_Uia64_install_cursor.S
(Logical change 1.84)
(REASON_SYSCALL): Ditto.
(access_reg): Use __uc_get_reason() to determine how ucontext_t was created.
Handle UNW_IA64_AR_BSP differently depending on whether or not
ucontext_t was created by a syscall. Ditto for UNW_IA64_IP and
UNW_IA64_CFM. Add debug statement.
(Logical change 1.77)

(tdep_find_proc_info) [HAVE_DLMODINFO): Declare new type "struct unwind_header"
to accommodate HP-UX unwind header. Fetch unwind table from this
header.
