Bug ID: 99015
Summary: ICE: Max. number of generated reload insns per insn is
achieved (90)
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: inline-asm
Assignee: unassigned at gcc dot gnu.org
Reporter: zhan3299 at purdue dot edu
Target Milestone: ---
Another inline-asm issue causes an ICE.
--- poc.c starts ---
int main() {
asm("" : : "fq"(.100));
}
--- poc.c ends ---
The version of GCC is 10.2.0 x86-64, and running 'gcc -O1 poc.c ' can trigger
the ICE.
--- error trace starts ---
$ gcc -O1 poc.c
during RTL pass: reload
test.c: In function ‘main’:
test.c:3:1: internal compiler error: maximum number of generated reload insns
per insn achieved (90)

This issue only occurs when compiling with -O1 and higher, but does not with
-O0.
I also test other versions of GCC. It seems to affect GCC version 8.1 and
higher, but not version 7.5 and lower.
This issue may be similar with
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98991. However, as #98991
additionally affects GCC version 7.5 and lower, I suspect they are different.

It seems clang at any optimization level can compile this. GCC at -O0 can also
compile it.

Works on the trunk, gcc-13 still fails. Removing gcc-14 regression marker.
