2012-04-30Adjust relevant test cases wrt -ftrack-macro-expansion=[0|2]Dodji Seketeli1-1/+1
Even after all the patches I have already submitted, some test cases where errors happens on tokens that are defined in macros see their output change in an incompatible way, when you run them with or without -ftrack-macro-expansion. I think this is expected, because the (spelling) locus inside the definition of the macro pointed to with -ftrack-macro-expansion is different from the locus of the expansion point of the macro pointed to without -ftrack-macro-expansion. In those cases this patch either adjusts the test case and forces it be run either with -ftrack-macro-expansion, or it just forces it to be run without -ftrack-macro-expansion. There are so many libstdc++ tests that were failing because of that benign issue that I preferred to just run them with -ftrack-macro-expansion diabled, after inspecting each of them to be sure there was nothing more serious underneath. Boostrapped on x86_64-unknown-linux-gnu against trunk with and without -ftrack-macro-expansion turned on. gcc/testsuite/ * objc.dg/foreach-7.m: Force the test case to run without -ftrack-macro-expansion. * c-c++-common/tm/attrib-1.c: Likewise. * c-c++-common/warn-ommitted-condop.c: Likewise. * gcc.dg/assign-warn-1.c: Likewise. * gcc.dg/assign-warn-2.c: Likewise. * gcc.dg/attr-alloc_size.c: Likewise. * gcc.dg/builtin-stringop-chk-1.c: Likewise. * gcc.dg/builtin-stringop-chk-2.c: Likewise. * gcc.dg/builtin-strncat-chk-1.c: Likewise. * gcc.dg/c90-const-expr-9.c: Likewise. * gcc.dg/c99-const-expr-9.c: Likewise. * gcc.dg/cpp/direct2.c: Likewise.
