--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
I don't see it on a big-endian powerpc64 even with -mlra -mvsx -mvsx-timode but
I can reproduce/confirm it with those options on powerpc64le (I did miss those
on my first attempt).
$ cat u.c && /build/gcc-trunk/gcc/xgcc -B /build/gcc-trunk/gcc -S -Wall -Wextra
-S -mlra -mvsx-timode u.c
typedef union { _Decimal128 a; } u_t;
extern u_t fn2 (u_t);
u_t
fn1 (void)
{
return fn2 (fn1 ());
}
u.c: In function ‘fn1’:
u.c:7:1: internal compiler error: Max. number of generated reload insns per
insn is achieved (90)
}
