Now that i386-pc-solaris2.10 bootstraps again after the IRA merge, the first
testsuite run revealed that all eh tests fail, affecting at least the g++
tests,
ada/acats and libjava. The symptom is always the same; I take
FAIL: g++.dg/eh/alias1.C execution test
as an example.
Running alias1.exe under gdb, I get the following stacktrace:
Program received signal SIGABRT, Aborted.
0xfedf5cd5 in _lwp_kill () from /lib/libc.so.1
(gdb) up
#1 0xfedf2b96 in thr_kill () from /lib/libc.so.1

#7 0x08050b51 in main ()
So the gcc_assert call in _Unwind_SetSpColumn causes this.
Maybe one of the recent dwarf2 undwind patches has caused this?
gcc was configured with --with-gnu-as --with-as=/usr/sfw/bin/gas, where
/usr/sfw/bin/gas is gas 2.15. gcc/auto-host.h has
auto-host.h:#define HAVE_GAS_CFI_DIRECTIVE 1
auto-host.h:#define HAVE_GAS_CFI_PERSONALITY_DIRECTIVE 0
I'm filing this under other since no other component seemed appropriate.

gas 2.15 is helplessly outdated and buggy. Can you retry with

Unfortunately, passing in BOOT_CFLAGS='-g -O2 -fno-dwarf2-cfi-asm' didn't
help (the value wasn't picked up from the environment). Even if I manually
set BOOT_CFLAGS like that in the toplevel Makefile, it isn't passed down to
the libgcc and libstdc++-v3 builds, and manually compiling an individual
testcase with -fno-... isn't enough. If I add -fno-... to
i386-pc-solaris2.10/libgcc/Makefile, rebuild libgcc and a testcase with
-fno-..., the test passes.
On the other hand, I tried bootstrapping with the current binutils 2.18
release, which makes no difference, so this doesn't seem to be a gas
problem.

Subject: Re: [4.4 regression] All Solaris/x86 eh tests fail
I've done some further debugging: contrary to what gdb suggested, the
reason for the abort is the gcc_assert call in unwind-dw2.c
(uw_init_context_1):
code = uw_frame_state_for (context, &fs);
gcc_assert (code == _URC_NO_REASON);
Single-stepping at the assembler level, I find that code is
_URC_END_OF_STACK, i.e. _Unwind_Find_FDE () in uw_frame_state_for ()
returned NULL.
Since this code is such a maze, I'm hard pressed to further debug this, so
any guidance is appreciated.

See http://sourceware.org/ml/binutils/2008-09/msg00195.html
Now someone needs to write a configure test for the compiler.

I'm a bit unsure how to test this right now: what I find is that C objects
have read-only .eh_frame sections and use .cfi* directives, while C++, Java
and Ada objects have read-write .eh_frame sections and still use .eh_frame
sections directly emitted by the compiler.

I think that we should assemble some C code with CFI directives and see whether
the resulting .eh_frame is read-only; if so, HAVE_GAS_CFI_DIRECTIVE must be set
to 0 instead of 1. This should discriminate between 2.18 and upcoming 2.19.
That the non-C compilers still emit .eh_frame directly is unexpected I'd think.

That's what I did in my patch at
http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00249.html
I could just take the current test code for gcc_cv_as_cfi_directive as is
and inspect the object file with objdump on Solaris. Using C code directly
with gcc -fexceptions -fdwarf2-cfi-asm didn't work since it relies upon the
bootstrap compiler being gcc and sufficiently recent to support
-fdwarf2-cfi-asm, leading to comparions failures upon a mismatch.
> That the non-C compilers still emit .eh_frame directly is unexpected I'd think.
I think I'll raise a separate PR for that and add rth to the Cc:.

If you have prehistoric assembler which doesn't support .cfi_personality
directive, then .cfi_* directives can't be used for C++.

The decision is made in dwarf2out_do_cfi_asm:
/* Decide whether to emit frame unwind via assembler directives. */
int
dwarf2out_do_cfi_asm (void)
{
int enc;
#ifdef MIPS_DEBUGGING_INFO
return false;
#endif
if (!flag_dwarf2_cfi_asm || !dwarf2out_do_frame ())
return false;
if (!eh_personality_libfunc)
return true;
if (!HAVE_GAS_CFI_PERSONALITY_DIRECTIVE)
return false;
/* Make sure the personality encoding is one the assembler can support.
In particular, aligned addresses can't be handled. */
enc = ASM_PREFERRED_EH_DATA_FORMAT (/*code=*/2,/*global=*/1);
if ((enc & 0x70) != 0 && (enc & 0x70) != DW_EH_PE_pcrel)
return false;
enc = ASM_PREFERRED_EH_DATA_FORMAT (/*code=*/0,/*global=*/0);
if ((enc & 0x70) != 0 && (enc & 0x70) != DW_EH_PE_pcrel)
return false;
return true;
}
On Solaris with Sun ld, ASM_PREFERRED_EH_DATA_FORMAT is defined so that at
least one of the 2 tests will always return false. Therefore the only way
to have dwarf2out_do_cfi_asm return true is
if (!eh_personality_libfunc)
return true;
The C++, Java and Ada compilers unconditionally register their personality
routine, whereas the C compiler doesn't, even with -fexceptions: if there
is no EH action in the code, it doesn't register it. Hence the discrepancy.
