>Description:
Hello,
I notice that this bug has been reported many times, for example in #4555, #4387, #4384, #3835, #3214, and #2426. However, the bug reporting guidelines say to report new bugs as followups to old ones.
I have developed a minimal test case that will reproduce "Internal compiler error in eliminate_regs, at reload1.c:2576":
void testfunc(char* foo, int bar)
{
fd_set readfds;
fd_set rfds = readfds;
switch (bar)
{
case 0:
break;
default:
if ((__extension__ ({register char __result; __asm__
__volatile__ ("btl %1,%2 ; setcb %b0" : "=q" (__result) : "r" (0), "m"
(*(&rfds)->fds_bits) : "cc"); __result; })))
break;
}
}
Compile this with -O[23s] and it will ICE. -O[01] will not cause it to.
>How-To-Repeat:
Compile the self-contained testcase contained in the description.
