[Bug target/58158] internal compiler error: in extract_insn, at recog.c:2150 while compiling ImageMagick on mipsel

It works correctly for -march=octeon/-march=mips32/-march=mips64 .

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58158 Andrew Pinski pinskia at gcc dot gnu.org changed: What|Removed |Added Status|UNCONFIRMED |NEW Last reconfirmed||2013-08-22 Host|mipsel-linux-gnu| Ever confirmed|0 |1 Build|i486-linux-gnu (gcc (Debian | |4.8.1-6) 4.8.1) | --- Comment #6 from Andrew Pinski pinskia at gcc dot gnu.org --- The backend says we have conditional moves on the floating point CC modes and expands it that way but really the target says we don't and it causes the ICE. Since it is only loongson2f only bug I am not going to fix it. I will let the loongson maintainer fix it since I don't know what loongson2f really has when it comes to conditional moves. Confirmed.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58158 --- Comment #4 from Andrew Pinski pinskia at gcc dot gnu.org --- (In reply to Mikael Pettersson from comment #3) Started with the Improve COND_EXPR expansion patch in r187183. Still occurs with recent trunk and head of 4.8 branch. Author CC:d. That means it was exposed by that. We have had many target (PPC, x86, and arm) specific bugs due to this patch too. This is not surprising we have one in MIPS too. Though I did test on mips64 (only n64 and n32 and not loongson though).

--- Comment #1 from Aaro Koskinen aaro.koskinen at iki dot fi ---
A simplified reproducer:
$ cat bar.c
extern void foo(void);
static inline double max(const double x, const double y)
{
return (x y) ? x : y;
}
void bar(int d)
{
int i;
for (i = 0; i (int)max(100.0 * d, 1.0); i++) {
foo();
}
}
$ gcc -c -O2 bar.c
bar.c: In function 'bar':
bar.c:15:1: error: unrecognizable insn:
}
