Bug ID: 111058
Summary: __builtin_nans (and its friends) compiles to an
external call to __builtin_nans for unsupported tag
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: xry111 at gcc dot gnu.org
Target Milestone: ---
double test(void)
{
return __builtin_nans("xxx");
}
compiles to:
test:
.LFB0:
.cfi_startproc
leaq .LC0(%rip), %rdi
jmp __builtin_nans@PLT
.cfi_endproc
We should refer to "nans" instead of "__builtin_nans" in the generated code.
Though nans does not exist in libm for now, it may be added into a future libm
version or the user can provide their own nans implementation.
