Craig Topper 74169dcf45 Improve handling of EnforceSmallerThan. Remove all types that are smaller from the larger set not just the smallest type from the smaller set. Ensure 'smaller' vectors have the same or fewer total bits. Similar for 'larger' vectors.

Craig Topper 6e1faaf886 Don't use EnforceSmallerThan for EnforceVectorSubVectorTypeIs. EnforceSmallerThan doesn't handle vectors quite right and should really enforce that vectors have the same number of elements. Add explicit checks for vector element count differing in EnforceVectorSubVectorTypeIs instead. This removes some unnecessary type checks in X86GenDAGISel.inc.

David Woodhouse caaa2850c0 [x86] Fix disassembly of MOV16ao16 et al. 
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.

Lang Hames 06234ec147 Add FPExt option to CCValAssign::LocInfo. When generating calling-convention 
promotion code, Tablegen will now select FPExt for floating point promotions
(previously it had returned AExt, which is not valid for floating point types).

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.

Craig Topper ae11aed9d7 Separate the concept of 16-bit/32-bit operand size controlled by 0x66 prefix and the current mode from the concept of SSE instructions using 0x66 prefix as part of their encoding without being affected by the mode. 
This should allow SSE instructions to be encoded correctly in 16-bit mode which r198586 probably broke.

Alp Toker 749971901a lit: Provide source locations in cfg files with older Python versions 
This commit prospectively brings the benefits of r198766 to older supported
Python versions (2.5+).

Tested with Python 2.6, 2.7, 3.1 and 3.3 (!)

Alp Toker f0a245944e lit: execfile() isn't present in Python 3.3 
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.

Kostya Serebryany a6afef7a51 reapply r198858: Disable LeakSanitizer in TableGen binaries, see PR18325; this time LeakSanitizerIsTurnedOffForTheCurrentProcess is used instead of __lsan_is_turned_off

Alp Toker 2a2a354ee9 Revert "Disable LeakSanitizer in TableGen binaries, see PR18325" 
To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.

See the list discussion for details.

This reverts commit r198858.

Alp Toker 9e628916f6 lit: Provide file location in cfg error messages 
Python doesn't do a good job at diagnosing string exec() so use execfile()
where available.

This should be a timesaver when trying to get to the bottom of build bot
failures.

Before:

    File "llvm/utils/lit/lit/TestingConfig.py", line 93, in load_from_path
      exec("exec data in cfg_globals")
    File "<string>", line 1, in <module>
    File "<string>", line 194, in <module>
  NameError: name 'typo' is not defined

After:

    File "llvm/utils/lit/lit/TestingConfig.py", line 95, in load_from_path
    execfile(path, cfg_globals)
    File "clang/test/lit.cfg", line 194, in <module>
      typo
      ^~~~
  NameError: name 'typo' is not defined

David Woodhouse 32da3c8f3b [x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understand 
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. So add that to the disassembler.

Hm, perhaps we do need an AdSize16 bit after all?

Craig Topper 7d4e01cdcb Don't use PrintFatalError(which calls exit) for 'Primary decode conflict'. Just skip emitting the table. This way the main function will delete the output file instead of it remaining empty and confusing dependency checks if build is invoked a second time.

Hal Finkel 49f1c2a733 [TableGen] Handle ValueType in CodeGenDAGPatterns GetNumNodeResults 
A ValueType in a pattern dag is a type cast, and GetNumNodeResults should
handle it (the type cast has only one result).

This comes up, for example, during the type checking of pattern fragments, for
example, AArch64's Neon_combine_2d fragment is:
  dag Operands = (ops node:$Rm, node:$Rn);
  dag Fragment = (v2f64 (concat_vectors (v1f64 node:$Rm), (v1f64 node:$Rn)));
