- Subject: [PATCH] testsuite: Turn -fgnu-tm test into link test
Hi,
using the -fgnu-tm option fails for targets not supporting libitm with
a *link* failure. So the compile test wasn't sufficient.
With the attached patch the following failures disappear on s390 and
s390x:
FAIL: gcc.dg/lto/trans-mem-1 c_lto_trans-mem-1_0.o-c_lto_trans-mem-1_1.o link, -flto -fgnu-tm
UNRESOLVED: gcc.dg/lto/trans-mem-1 c_lto_trans-mem-1_0.o-c_lto_trans-mem-1_1.o execute -flto -fgnu-tm
FAIL: gcc.dg/lto/trans-mem-2 c_lto_trans-mem-2_0.o-c_lto_trans-mem-2_1.o link, -flto -fgnu-tm
UNRESOLVED: gcc.dg/lto/trans-mem-2 c_lto_trans-mem-2_0.o-c_lto_trans-mem-2_1.o execute -flto -fgnu-tm
FAIL: gcc.dg/lto/trans-mem-4 c_lto_trans-mem-4_0.o-c_lto_trans-mem-4_1.o link, -flto -fgnu-tm
UNRESOLVED: gcc.dg/lto/trans-mem-4 c_lto_trans-mem-4_0.o-c_lto_trans-mem-4_1.o execute -flto -fgnu-tm
XPASS: gcc.dg/tree-ssa/20040204-1.c scan-tree-dump-times optimized "link_error" 0
Ok for mainline?
Bye,
-Andreas-

* lib/target-supports.exp (check_effective_target_fgnu_tm): Make
it an "executable" test in order to check whether linking against
libitm works.
