Bug ID: 106510
Summary: arm : ice in gimple_range_operand1, at
gimple-range-fold.cc:485
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

C source code
For the C testsuite file ./gcc.c-torture/execute/ieee/compare-fp-4.c compiled
by
recent gcc trunk 32 bit ARM cross compiler, does this:
during GIMPLE pass: threadfull

--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:
void ine_ok() {
float y, x;
if (x < y || x > y || y)
abort();
}
Same problem exists on native x86_64, so I will have a go at finding a git
range.

Most likely caused by r13-1933-g24012539ae3410 .

Git range seems to be 82ac4cd213867be9..6d41f7c39cff9fb5, a range of 22
commits.

Most likely commit is in git range, so perhaps Aldy might be willing to offer
an opinion ?

BTW, test exhibits undefined behavior, though putting x and y as arguments also
ICEs.
GORI wants all the relational operators defined, and is asserting so.
What's missing is the LGBT operator ;-).

I won't be able to get to this today. If someone could test and push, it'd be
great. Otherwise, I'll get to it tomorrow.

Do not register edges for statements not understood.
Previously, all gimple_cond types were undserstoof, with float values,
this is no longer true. We should gracefully do nothing if the
gcond type is not supported.
PR tree-optimization/106510

* gimple-range-fold.cc (fur_source::register_outgoing_edges):
Check for unsupported statements early.
