Bug ID: 103395
Summary: [9/10/11/12 Regression] ICE on qemu in arm
create_fix_barrier
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
Since GCC 5 (r208990 still works fine, r215478 ICEs already up to current
trunk)
the following testcase ICEs on armv7hl-linux-gnueabi with -O2:
void
foo (void)
{
__asm__ ("\n\n\n\n\n\n\n\n\n\n"
"\n\n\n\n\n\n\n\n\n\n"
"\n\n\n\n\n\n\n\n\n\n"
"\n\n\n\n\n\n\n\n\n\n"
"\n\n\n\n\n\n\n\n\n\n"
"\n\n\n\n\n\n\n\n\n\n"
"\n" : : "nor" (0), "nor" (0));
}
Removing just one newline makes the ICE go away. get_attr_length for such
inline asm is 248 bytes (estimation) and the arm minipool code is apparently
upset about it.
