Sanjoy Das	edadecbe66	Fix test case. r230921 broke backend-optimization-failure.cpp: after r230921, LLVM no longer emits an expression to compute 'Length - 1' and this perturbs LoopSimplify enough to emit the warning on line 10 instead of line 9. This is a review request to fix the test case once I re-land r230921. llvm-svn: 231020	2015-03-02 21:47:47 +00:00
David Majnemer	467e856600	Adjust test to handle fallout from r217102. llvm-svn: 217104	2014-09-03 23:20:58 +00:00
NAKAMURA Takumi	6096d44f76	clang/test/Misc/backend-optimization-failure.cpp: Appease to add -triple=x86_64. FIXME: Could this be made generic? llvm-svn: 213441	2014-07-19 01:17:32 +00:00
Tyler Nowicki	f8a767df67	Recommit: Handle diagnostic warnings in Frontend diagnostic handler. Clang uses a diagnostic handler to grab diagnostic messages so it can print them with the line of source code they refer to. This patch extends this to handle optimization failures that were added to llvm to produce a warning when loop vectorization is explicitly specified (using a pragma clang loop directive) but fails. Update renames warning flag name to avoid indicating the flag's severity and adds a test. Reviewed by Alp Toker llvm-svn: 213400	2014-07-18 19:40:19 +00:00
