             Bug #: 52259
           Summary: All tm tests fail on targets without pthread support
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: greta.yo...@arm.com
            Target: arm-none-eabi


All tm tests fail on arm-none-eabi, for example:

/work/builds/a9-feb15/arm-none-eabi/gcc2/gcc/xgcc
-B/work/builds/a9-feb15/arm-none-eabi/gcc2/gcc/
/work/local-checkouts/gcc-fsf/gcc/testsuite/c-c++-common/tm/20100127.c   
-fgnu-tm -O -fdump-tree-tmmark -DSTACK_SIZE=16384 -S    -o 20100127.s   
(timeout = 60)
xgcc: error: unrecognized command line option '-pthread'
compiler exited with status 1

Caused by trunk r184174, which added -pthread to the command line of all tm
tests without checking that the target supports pthread:
