Require an x86 target for the thinlto_backend.ll test. llvm-svn: 273361
2016-06-22 09:40:47 +08:00
; REQUIRES: x86-registered-target
CodeGen: Replace test/CodeGen/thinlto_backend.c with a functional test. This new test tests that functions are capable of being imported, rather than that the import pass is run. This new test is compatible with the approach being developed in D20268 which runs the importer on its own rather than in a pass.
