This is actually a bootstrap failure on i386-unknown-freebsd5.4, but with
some work I managed to destill this radically.
When invoking `${BUILDDIR}/gcc/xgcc -B${BUILDDIR}/gcc -O1 x.cc` on
#define f(x) ({ unsigned tmp=x; tmp; })
unsigned foo(unsigned x) {
return __builtin_constant_p(x) ? 0 : f(x);
}
I, and several other FreeBSD committers, get
x.cc: In function 'unsigned int foo(unsigned int)':
x.cc:6: internal compiler error: in voidify_wrapper_expr, at gimplify.c:1015
This regression was introduced between 23:03 GMT +0200 on December 4th and
the same time on December 5th 2006.
