![]() local frame causes problem. For example: void f(StructToPass s) { g(&s, sizeof(s)); } will cause problem with tail-call since part of s is passed via registers and saved in f's local frame. When g tries to access s, part of s may be corrupted since f's local frame is popped out before the tail-call. The current fix is to disable tail-call if getVarArgsRegSaveSize is not 0 for the caller. This is a conservative approach, if we can prove the address of s or part of s is not taken and passed to g, it should be okay to perform tail-call. rdar://12442472 llvm-svn: 165853 |
