[Bug target/27158] [4.1/4.2 regression] ICE in extract_insn with -maltivec
------- Comment #11 from bonzini at gnu dot org 2006-04-18 15:20 -------
... but then anyway the bug pops up in reload. So it is definitely the same
bug as PR24230, and here is a modified version of the PR24230 testcase:
/* Compile with -O2 -maltivec */
#define REGLIST \
"77", "78", "79", "80", "81", "82", "83", "84", "85", "86",\
"87", "88", "89", "90", "91", "92", "93", "94", "95", "96",\
"97", "98", "99", "100", "101", "102", "103", "104", "105", "106",\
"107", "108"
typedef __attribute__ ((vector_size (16))) float v4sf;
void
foo (int H)
{
volatile v4sf tmp;
while (H-- > 0)
{
asm ("" : : : REGLIST);
tmp = (v4sf) __builtin_altivec_vspltisw (1);
}
}
fails on 4.1, didn't test on 4.2.
