for awhile, but it's good to make this official.  

Just to be clear, Doug and Ted "elected" me to this position.

Might as well add myself to the credits list while I'm at it.

Make the FixedLengthDecoderEmitter smart enough to autogenerate decoders for encodings like "let Inst{11-7} = foo;", where the RHS has no bitwidth specifiers.

PR10495.

The FixedLenDecoder needs to gracefully handle failing per-instruction decoder hooks in addition to per-operand decoder hooks.

llvm-svn: 136645

TableGen deps introduced in r136023. This completes the fixing that
dgregor started in r136621. Sorry for missing these the first time
around.

This should fix some of the random race-condition failures people are
still seeing with CMake.

llvm-svn: 136643

avoid returning early for v8i32 types, which would only be valid for
vector with all zeros. Also split the handling of zeros and ones into separate
checking logic since they are handled differently. This fixes PR10547

one than one successor goes to the same block.

Add a clear() operation to MCInst, to drop all of its operands.  Useful for the disassembler, where we may realize fairly late into decoding that something is wrong and need to reset.

llvm-svn: 136634

llvm-svn: 136623

Update CMake target names for tablegen-generated data in the X86 and ARM targets. This should fix the CMake build with MSVC.

accordingly.

them properly. Specifically, the disassembler clearly attempts to
initialiaze all TargetInfo, MCTargeDesc, AsmParser, and Disassembler
sublibraries of registered targets. This makes the CMakeLists accurately
reflect this intent in the code.

This should fix the last of the link errors that I have gotten reports
of on OS X, but if anyone continues to see link errors, continue to
pester me and I'll look into it.

This adds the 'resume' instruction class, IR parsing, and bitcode reading and
writing. The 'resume' instruction resumes propagation of an existing (in-flight)
exception whose unwinding was interrupted with a 'landingpad' instruction (to be
added later).

decide whether condition is likely to be true this way:

x == 0  ->  false
x <  0  ->  false
x <= 0  ->  false
x != 0  ->  true
x >  0  ->  true
x >= 0  ->  true

While this generally helped x86-64, there was some large regressions
for i386.

rules to the new explicitly listed TableGen rules. Somehow I missed this
in my original sweep.

llvm-svn: 136567

sub-library for the targets depended on the core target CodeGen library.
This completely undermined the careful work to separate the those
libraries, especially the MC-layer ones. This surfaced as circular
dependencies when the libraries were built as shared libraries where
CMake doesn't allow cycles.

This should fix PR10537. I'll watch the bots to see if there is fallout
on other platforms.
