(In reply to comment #7)
I fixed the test case to not expect the unimplemented optimization in r157197,
however, it would be nice to ensure the async signal handlers can handle
unaligned stacks and to perform this optimization. I'm fairly certain the
signal handers have to cope as code gen can do:
_h:
subl$12, %esp
movl$1, %eax
addl$12, %esp
ret
for int h () { return 1; } and certainly we can take a signal at _h+0, where
esp isn't aligned. Given that, we can omit sp alignments for leaf functions
(and no tail calls either), even on machines where otherwise an alignment is
required, as long as any variables on the stack are correctly aligned.
When this optimization is added, we can undo the r157197 change.
My proposed patch to fix PR36502...
http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00237.html
that enables stack realignment on intel darwin also solves this PR as well.
Comparing the output from gcc trunk before and after my patch, I see...

diffs of the lines replaced out of configure.ac from each location (gcc, libgcc

[Bug target/45524] r163815/r163816 produces new regressions on x86_64-apple-darwin10
--- Comment #11 from howarth at nitro dot med dot uc dot edu 2010-09-04 02:27 --- I am not worried about $host vs $target but rather the nuances in the xno case for x$enable_decimal_float in the original code. For gcc/configure.ac, this sets... enable_decimal_float=dpd but that case is not handled in gcc/configure.ac. Likewise comparing gcc/configure.ac to libdecnumber.ac,that case is also ignored but there also is a wrapping test around the entire case statement of... if test x$enable_decimal_float = xyes -o x$enable_decimal_float = xno; then these subtleties have not been extended into dfp.m4 nor has the underlying reason for them been addressed. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45524

--- Comment #13 from howarth at nitro dot med dot uc dot edu 2010-09-04 03:39 --- Reverting both libgcc/configure.ac and libdecnumber/configure.ac and regenerating these files is insufficient as well to eliminate the regressions on darwin. Looking at the remaining changes in gcc/configure.ac it is obvious way this change badly breaks non-linux targets. http://gcc.gnu.org/viewcvs/trunk/gcc/configure.ac?r1=163815r2=163814pathrev=163815 The author cut out two sections from gcc/configure.ac and pasted them together in dfp.m4. The intervening section... dfp=`if test $enable_decimal_float != no; then echo 1; else echo 0; fi` AC_DEFINE_UNQUOTED(ENABLE_DECIMAL_FLOAT, $dfp, [Define to 1 to enable decimal float extension to C.]) is now moved to the end, breaking the original logic. This is without even considering the other subtleties in the same code from libgcc/configure.ac and libdecnumber/configure.ac that has been simply ignored. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45524

(In reply to comment #3)
I think I can prove that my patch doesn't affect code generation, except
possibly on the SPARC, so I'm a little skeptical about your diagnosis. Are
you
sure it's not r163679 instead?
Clean bootstrap of r163659 followed by 20 instances of...
make -k check-gcc RUNTESTFLAGS=builtins.exp=sprintf-chk.c
--target_board=unix'{-m32,-m64}'
produce 20 instances of all 40 tests passing. Repeated clean bootstrap for
r163660 and 20 instances
of the same make check statement produced 10 out of 20 times the failure...

The evidence of r163660 being to blame looks pretty convincing to me.

Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.
Since this doesn't backtrace in gdb, I recompiled dwarf2out.c with the patch...

[Bug middle-end/45484] r163660 ICEs gcc.c-torture/execute/builtins/sprintf-chk.c compilation, -Os at -m32
--- Comment #9 from howarth at nitro dot med dot uc dot edu 2010-09-02 05:10 --- Note that in current gcc trunk (r163747) with... http://gcc.gnu.org/ml/gcc-patches/2010-08/msg01916.html and http://gcc.gnu.org/bugzilla/attachment.cgi?id=21650 the frequency of the test case ICEing the compiler is very low (less than 1%) but does still happen. I believe this bug just becomes more or less latent so it should be debugged at revision which best exposes it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45484
