The following foo.c which is a reduced case of libc/grp/initgroup.c
causes an ICE:
foo.c:13: error: unable to find a register to spill in class 'R0_REGS'
foo.c:13: error: this is the insn:
(insn:HI 28 32 34 1 (set (reg:SI 147 t)
(eq:SI (reg/v:SI 2 r2 [orig:161 result ] [161])
(const_int -1 [0xffffffffffffffff]))) 1 {cmpeqsi_t}
(insn_list:REG_DEP_ANTI 23 (insn_list:REG_DEP_ANTI 24 (insn_list:REG_DEP_ANTI 25
(insn_list:REG_DEP_TRUE 26 (nil)))))
(nil))
with -O2.
foo.c:
--
extern __thread int err __attribute__ ((tls_model ("initial-exec")));
int
foo (int n, int *grp)
{
int result;
do
result = bar (n, grp);
while (result == -1 && err == 22 && --n > 0);
return result;
}
