--- Comment #9 from Shubham Narlawar ---
I found the ICE - "internal compiler error: in hoist_memory_references, at
tree-ssa-loop-im.c:2615" with below testcase when compiled with -Og on trunk.
The testcase is obtained by fuzzing function attributes in Csmith -
--Testcase---
a, b, c, d, f;
**e;
g() __attribute__((optimize("Ofast")));
g(h) {
int *i =
for (; f;) {
c = 5;
for (; c; c--) {
char *j =
**e = (h && d) == a;
*i = 0;
*j = 0;
}
}
}
-
I see above ICE has been fixed now.

[Bug target/91106] internal compiler error: output_operand: invalid use of register 'frame'
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91106
--- Comment #2 from Shubham Narlawar ---
(In reply to Richard Biener from comment #1)
> Did you paste the correct reduced testcase?
Here is the original reduced test case obtained from Creduce -
#pragma pack(1)
struct a {
int b;
char c
};
union {
struct a b
} __attribute__((aligned(32), transparent_union)) d;
e() { f(d); }
I tried to fix warnings by putting semicolon, data type and function
declaration where ever required.

I have opened a new bug report for above. Here is the link.

I attached the preprocessed code of the original program in the report.

--- Comment #5 from Shubham Narlawar ---
I got an ICE as below on gcc-8.2 at optimization -O3 as below-
internal compiler error: in expand_LOOP_VECTORIZED, at internal-fn.c:2409
--REDUCED CODE
a;
b() {
void *c = &
for (;;)
d:
if (a)

else
a = ({ 0 < b; });
}
Is this the same bug as above filed? If it is fixed on gcc-8.0, what causes ICE
on gcc-8.2?
