Summary: FAIL: gcc.dg/analyzer/mkostemp-1.c test for warnings
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
In r17-409-g8376a674e3564f, 2 out of the 4 redundant tests fail when testing
for arm-none-eabi:
105 │ void test_redundant_o_creat (void)
106 │ {
107 │ char tmpl[] = "/tmp/testXXXXXX";
108 │ mkostemp (tmpl, O_CREAT); /* { dg-warning "'mkostemp' flags argument
should not include 'O_RDWR', 'O_CREAT', or 'O_EXCL' as these are already
implied" } */
109 │ }
110 │
111 │ void test_redundant_o_excl (void)
112 │ {
113 │ char tmpl[] = "/tmp/testXXXXXX";
114 │ mkostemp (tmpl, O_EXCL); /* { dg-warning "'mkostemp' flags argument
should not include 'O_RDWR', 'O_CREAT', or 'O_EXCL' as these are already
implied" } */
