--- Comment #3 from Zdenek Sojka  ---
(In reply to Andrew Pinski from comment #2)
> Most likely a dup of bug 113967

I am sorry for the confusion; the bugzilla stopped responding while creating
this PR for the first time, and since I there wasn't any new message in the
gcc-bugs mailing list, I thought the PR wasn't created, and I created PR113967
instead.

[Bug tree-optimization/113753] New: wrong code with _BitInt(129) multiplication and division at -O2

[zsojka at seznam dot cz via Gcc-bugs]

Bug ID: 113753
   Summary: wrong code with _BitInt(129) multiplication and
division at -O2
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Keywords: wrong-code
  Severity: normal

Output:
$ x86_64-pc-linux-gnu-gcc -O2 testcase.c
$ ./a.out 
Aborted

The result of "u * m" does not fit into unsigned _BitInt(129), but at -O2, 'm'
is returned.

I have a strong feeling of reporting this before, but I can't find the original
PR. Sorry for the dup, if I searched poorly.

This probably needs RTL checking enabled.

Compiler output:

Aborted

-fsanitize=undefined fixes the problem:
$ x86_64-pc-linux-gnu-gcc testcase.c -fsanitize=undefined && ./a.out
(no output)

At the ASM level, at -O1:
...
foo:
# testcase.c:7:   ub1 += (ub16 << 2) | ub8;
or  dil, BYTE PTR ub8[rip]  # _1, ub8
and edi, 1  # _4,

it seems the shift is removed; changing the type of ub1 to "unsigned
_BitInt(2)" fixes this.

Thank you for having a look.

The "regression" part is for the ICEing.

I would even say that with -funsigned-bitfields, the code is valid, but I am
not a language lawyer.
gcc-13, or gcc-14 without -std=2x, rejects the code though. On the other hand,
changing the "unsigned" to "signed", makes the code to be accepted, with the
default "signed" bitfields, so "int" and "signed" bitfield types are equal;
maybe my understanding of the "-funsigned-bitfields" as "any plain 'int'
bitfield is 'unsigned'" is incorrect.

I don't know if this is a _BitInt() issue, or if it's related to PR113144 (or
is a standalone issue), since it appears only when vectorisation is enabled.
