Here is a small program based on the traverso code, that exhibits the
error when built with -O2
gcc (Ubuntu/Linaro 4.5.2-1ubuntu2) 4.5.2
internal compiler error: in get_arm_condition_code, at
config/arm/arm.c:16985
any of these changes leads to successful build
- using long instead of 'long long'
- not using the shift operator
- not wrapping in a loop
#include limits.h
void sample_move_d32u24_sS (char *dst, char *src, unsigned long nsamples,
unsigned long dst_skip)
{
long long y;
while (nsamples--) {
y = (long long)(*src) 8;
if (y INT_MIN) {
*((int *) dst) = INT_MIN;
} else {
*((int *) dst) = (int)y;
}
}
}

[Bug 689887] Re: armel ICE gcc 4.5
An even smaller testcase
Changing INT_MIN to LONG_LONG_MIN in the conditional fixes the build.
(using it this way is arguably a bug in the codebase)
#include limits.h
void small(char *dst)
{
long long y;
while (1) {
y = (long long)(*dst) 8;
if (y INT_MIN) {
*((int *) dst) = 0;
} else {
*((int *) dst) = 1;
}
}
}

The ICE looks familiar, can you provide a preprocessed .i file as a testcase?
