When running the testsuite with mainline on i686-pc-linux-gnu with -fpic or -
fPIC, I get the following additional failures:
FAIL: gcc.dg/assign-warn-3.c (test for warnings, line 9)
FAIL: gcc.dg/assign-warn-3.c (test for warnings, line 13)
The expected warnings simply fail to appear with the extra flag. Warning
output should not be affected by this.

That no warning is emitted with -O and -O2 is expected since no inlining takes place. Just for curiosity I marked f0 and f1 in the test as inline and got the following results: gcc -c -O assign-warn-3.c: no warning !!! gcc -c -O2 assign-warn-3.c: warning gcc -c -O3 assign-warn-3.c: warning gcc -c -O assign-warn-3.c -fpic: warning gcc -c -O2 assign-warn-3.c -fpic: warning gcc -c -O3 assign-warn-3.c -fpic: warning Here I'd expect a warning in all six cases. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |reichelt at gcc dot gnu dot | |org Status|UNCONFIRMED |NEW Ever Confirmed| |1 Keywords| |diagnostic Last reconfirmed|0000-00-00 00:00:00 |2005-01-03 17:36:58 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19232 ^ permalink raw reply [flat|nested] 5+ messages in thread
