Hi All,
This changes the tests I committed for PR113287 to also
run on targets that don't support bitint.
Regtested on aarch64-none-linux-gnu, x86_64-pc-linux-gnu
and no issues and tests run on both.
Ok for master?
Thanks,
Tamar

But I'm afraid I have no idea how is this supposed to work on
non-bitint targets or where __BITINT_MAXWIDTH__ is smaller than 9020.
There is no loop at all there, so what should be vectorized?
I'd say introduce
# Return 1 if the target supports _BitInt(65535), 0 otherwise.
proc check_effective_target_bitint65535 { } {
return [check_no_compiler_messages bitint65535 object {
_BitInt (2) a = 1wb;
unsigned _BitInt (65535) b = 0uwb;
} "-std=c23"]
}
after bitint575 effective target and use it in the test.

Yeah It was giving an unresolved and I didn't notice in diff.

Sure, how's:

This changes the tests I committed for PR113287 to also
run on targets that don't support bitint.
Regtested on aarch64-none-linux-gnu, x86_64-pc-linux-gnu and no issues and
tests run on both.
Ok for master?

When the testcase was being adjusted for unsigned long -> unsigned long long,
two spots using long weren't changed to long long, so the testcase still warns
about UB in shifts.
Excess errors:
.../gcc/gcc/testsuite/gcc.dg/vect/vect-early-break_100-pr113287.c:28:48: warning: right shift count >= width of type [-Wshift-count-overflow]
Fixed thusly, committed to trunk as obvious.

of long.
