New Revision: 193381

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193381
Log:
Adding function attributes: 'always_patch_for_instrumentation' and
'never_patch_for_instrumentation' to always patch a function or to never
patch a function, respectively, when given the option
-mpatch-functions-for-instrumentation. Additionally, the attribute
always_patch_for_instrumentation disables inlining of that function.

        * gcc/c-family/c-common.c (handle_always_patch_for_instrumentation_attribute):
        Handle always_patch_for_instrumentation attribute and turn inlining off for
        the function.
        (handle_never_patch_for_instrumentation_attribute): Handle
        never_patch_for_instrumentation attribute of a function.
        * gcc/config/i386/i386.c (has_attribute): Checks the presence of an
        attribute.
        (check_should_patch_current_function): Takes into account
        always_patch_for_instrumentation or never_patch_for_instrumentation attribute
        when deciding that a function should be patched.
        * gcc/testsuite/gcc.target/i386/patch-functions-force-no-patching.c (int main):
        Test case to test for never_patch_for_instrumentation attribute.
        * gcc/testsuite/gcc.target/i386/patch-functions-force-patching.c: Test
        case to test for always_patch_for_instrumentation attribute.
