Bug ID: 116757
Summary: check_effective_target_fileio uses deprecated function
resulting in UNSUPPORTED
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
Tests like gcc.c-torture/execute/fprintf-2.c have a
dg-requires-effective-target on fileio but with "recent" glibc the test
# Check to see that file I/O functions are available.
proc check_effective_target_fileio { } {
return [check_no_compiler_messages fileio_available executable {
#include <stdio.h>
int main() {
char *n = tmpnam (NULL);
FILE *f = fopen (n, "w");
fclose (f);
remove (n);
return 0;
} } ""]
}
results in

fileio_available24825.c:(.text+0xa): warning: the use of `tmpnam' is dangerous,
better use `mkstemp'
UNSUPPORTED: gcc.c-torture/execute/fprintf-2.c -O0
this particular test uses gcc_tmpnam which could be modernized along the
effective target but cross-checking other users would be necessary. I'm
not sure we can prune this specific message from the test and still get
using tests pass.
