Commit fc532c1a0dc66bf23cac60f5363f180c6cbfefbc by Dan Liew Remove some non-determinism from the `Darwin/duplicate_os_log_reports.cpp` test. The test read from an uninitialized buffer which could cause the output to be unpredictable. The test is currently disabled so this won't actually change anything until the test is re-enabled.

Commit 1b6d29e06b07e518025b6f06445ad3275d6f5684 by maskray [Driver] Fix BooleanFFlag identifiers to use 'f' 'fno_' prefixes instead of suffixes

Commit 07e8a780d81bb58a0c7bd4da6cc0b9beaec3c788 by craig.topper [X86] Add pseudo instructions to use MULX with a single destination when the low result isn't used. The instruction is defined to only produce high result if both destinations are the same. We can exploit this to avoid unnecessarily clobbering a register. In order to hide this from register allocation we use a pseudo instruction and expand the result during MCInst creation. Differential Revision: https://reviews.llvm.org/D80500

Commit a23d1e9aff4d8cb752e227b3e16f887cf49c15d4 by maskray [llvm-objdump] Simplify reportError() and prepend outs().flush() As noticed by dblaikie. I don't know what code paths using reportError can cause stdout output to be interleaved with stderr, so no test is added now. Also drop an unneeded use of errs().fflush() in reportWarning(). I requested this in D64165.

Commit 439d27d79f58282b618881142244bbdcb1f28345 by maskray [llvm-objdump] Move llvm:: to llvm::objdump:: and qualifying definitions with objdump:: Or adding `static`. Qualifying definitions with `objdump::` comforms to the coding standards https://llvm.org/docs/CodingStandards.html#use-namespace-qualifiers-to-implement-previously-declared-functions

Commit 1ecf39d607acdb04c2bb5155e5f7265db2484511 by craig.topper [X86] Fix a place where we created MOVQ2DQ with a DstVT other than v2i64. The type profile and isel pattern have this type declared as being MVT::v2i64. But isel skips the explicit type check due to the type profile.

Commit a4dd45b7d09d8c12b87eaa0e6d1a92ce2b0defe0 by craig.topper [DAGCombiner] Move debug message and statistic update into CommitTargetLoweringOpt. This code was repeated in two callers of CommitTargetLoweringOpt. But CommitTargetLoweringOpt is also called from TargetLowering. We should print a message for those calls to. So sink the repeated code into CommitTargetLoweringOpt to catch those calls.

Commit 7c3b8077cc3feed2de3de6f3efb0627d619d1434 by craig.topper [X86] Add DAG combine to turn (v2i64 (scalar_to_vector (i64 (bitconvert (mmx))))) to MOVQ2DQ. Remove unneeded isel patterns. We already had a DAG combine for (mmx (bitconvert (i64 (extractelement v2i64)))) to MOVDQ2Q. Remove patterns for MMX_MOVQ2DQrr/MMX_MOVDQ2Qrr that use scalar_to_vector/extractelement involving i64 scalar type with v2i64 and x86mmx.

Commit dbda87186ec1b28a98d7a91a651b5a47c6f06d40 by craig.topper [X86] Remove unneeded bitconverts from isel patterns. NFC The types already match so TableGen is removing the bitconvert.
