46b7b8196c (is_cie_id): New function.
(parse_cie): Adjust for moving DWARF2 extra-info from
	unw_dyn_dwarf_fde_info_t to dwarf_cie_info.
	Add support for `S' augmentation ("special frames").
(dwarf_extract_proc_info_from_fde): Rename frm dwarf_parse_fde().
	Convert to returning data via dwarf_cie_info rather than
	unw_dyn-dwarf_fde_info_t.  Allow 0-length FDE since those
	can be used to indicate the end of the FDE-table.  Return
	the end of the FDE via *ADDRP.  Ignore CIEs (we may pick them
	up during linear searches through the FDE-table).
	Fill in the unwind-info only if really needed.  When needed,
	return the info via a dynamically allocated dwarf_cie_info
	structure.  Add support for `S' augmentation (ABI/tag pairs).

d9445c1f46 (handler): get_bsp() returns an integer, not a pointer.
(main): Do some silly FP computations.  On x86-64, this ensures
	that the signal handler invocations will always be called
	with the FPU-state saved as well.  Without this, the first
	signal was invoked without FPU-state, the second with, causing
	a spurious failure.

c14371409a (fetch_proc_info): Decrement IP before searching for dynamic/static
unwind-info, since DWARF expects us to do so (unlikey for ia64,
	where we are guaranteed that the (return) IP points to the
	correct unwind-info).

2004/11/17 02:43:39-08:00 mostang.com!davidm
(run_cfi_program): Switch over to using dwarf_cie_info instead of
	unw_dyn_dwarf_fde_info_t.
(fetch_proc_info): Clear c->pi before filling it in.
(put_unwind_info): If we got non-dynamic unwind-info, free it
	via a call to mempool_free().
(parse_fde): Switch over to using dwarf_cie_info instead of
	unw_dyn_dwarf_fde_info_t.
(apply_reg_state): Drop accessees to c->cfa_is_sp.

(run_cfi_program): Add missing newline in Debug statement.
(apply_reg_state): It was wrong to do a dwarf_get() on the CFA-location
	returned by eval_location_expr().  Instead, we must make sure
	we're dealing with a memory-location and, if so, just extract
	the memory address as the CFA.
	Also, update c->cfa only _after_ the other frame-state has
	been updated.  This seems to be necessary for correct parsing
	of the sigtramp unwind info.  Not sure yet this is 100% correct,
	but it gets us through Gtest-resume-sig.

ia64: Fix two typos in Gscript.c which showed when compiling

2005/04/07 12:19:38-07:00 hp.com!davidm
ia64: cache proc-info even for procedures which are never stepped over

This was an oversight that caused exception-handling to run a bit
slower than possible.  Specifically, the last procedure in an
exception-handling chain never got cached because it has only it's
proc-info inspected (to find the personality routine); the frame
was never stepped over (i.e., no script was ever built) and the info
never got into the cache.  This patch fixes the problem.

Fairly major overhaul of DWARF2 unwinder.  The major change is that
the auxiliary DWARF-info is maintained in a separate structure
(dwarf_cie_info, I may rename this to dwarf_aux_info) rather than
in an unw_dyn_info_t.  The latter seemed promising at the beginning,
but it's become clear that it was a bad idea so it's time to remove
it.
