In a previous commit (r199818) we added a const_cast to an existing subtarget info instead of creating a new one so that we could reuse it when creating the TargetAsmParser for parsing inline assembly. This cast was necessary because we needed to reuse the existing STI to avoid generating incorrect code when the inline asm contained mode-switching directives (e.g. .code 16). The root cause of the failure was that there was an implicit sharing of the STI between the parser and the MCCodeEmitter. To fix a different but related issue, we now explicitly pass the STI to the MCCodeEmitter (see commits r200345-r200351). The const_cast is no longer necessary and we can now create a fresh STI for the inline asm parser to use. Differential Revision: http://llvm-reviews.chandlerc.com/D2709 llvm-svn: 200929 |
