* [x86] Fix disassembly of MOV16ao16 et al.David Woodhouse2014-01-20
| | | | | | | | | | The addition of IC_OPSIZE_ADSIZE in r198759 wasn't quite complete. It also turns out to have been unnecessary. The disassembler handles the AdSize prefix for itself, and doesn't care about the difference between (e.g.) MOV8ao8 and MOB8ao8_16 definitions. So just let them coexist and don't worry about it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199654 91177308-0d34-0410-b5e6-96231b3b80d8

Any out-of-tree targets that were relying on AExt being returned for FP promotions will need to update their code check for FPExt instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199252 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | On the other hand, exec(compile()) doesn't work in older Python versions in the 2.x series. This commit introduces exec(compile()) with a fallback to plain exec(). That'll hopefully hit the sweet spot in terms of version support. Followup to r198766 which added enhanced source locations for lit cfg parsing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199006 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | Python doesn't do a good job at diagnosing string exec() so use execfile() where available.

| | | | | | | | | | It seems there is no separate instruction class for having AdSize *and* OpSize bits set, which is required in order to disambiguate between all these instructions.
