[Bug c/38387] psim miscompiled [regression]

[joel at gcc dot gnu dot org]

------- Comment #11 from joel at gcc dot gnu dot org  2008-12-09 20:11 -------
I wondered if I had a mistake in my testing since some of the later results
didn't make sense as I thought about them.  I am pretty convinced now this 
is NOT a strict aliasing problem in psim.  

Broken when configuring GDB with:

(CFLAGS="-Wstrict-aliasing=2 -O2 -Wno-error -fno-strict-aliasing"
~/old/test-gcc/gdb-6.8/configure --disable-werror --target=powerpc-rtems4.10
--enable-sim --enable-sim-hardware --enable-timebase --enable-sim-trace
--prefix=/n/12/joel/test-gcc/install/

$ gcc --version
gcc (GCC) 4.4.0 20081205 (experimental) [trunk revision 142492]
