This test causes GCC to ICE in output_constant_pool_2 on powerpc64-linux
with -m32. The ICE goes away without the typedef or if the variable
is local.
The test case is extracted from gcc.dg-struct-layout-1/t001.
typedef float Tal1float __attribute__((aligned (1)));
struct { Tal1float f; } s;
void foo (void) { s.f = 1.0; }
When compiled with powerpc64-unknown-linux-gnu from 20041013 mainline:
elm3b11% /opt/gcc-nightly/mline/bin/gcc -m32 bug.c
bug.c: In function 'foo':
bug.c:3: internal compiler error: in output_constant_pool_2, at /varasm.c:3074
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
GCC for powerpc-eabisim gets the same ICE.
