NEON immediates are "interesting". Start of the work to handle parsing them
in an 'as' compatible manner. Getting the matcher to play nicely with
these and the floating point immediates from VFP is an extra fun wrinkle.

Fix unused variable warning in the rare circumstance that we have no feature-dependent instructions.

This removes support for building llvm-gcc. It will eventually add support for
building other projects.

Add X86 INVPCID instruction. Add 32/64-bit predicates to INVEPT, INVVPID, VMREAD, and VMWRITE to remove hack from X86RecognizableInstr.

string, pass it around as an enum.

the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

llvm-svn: 142106

Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand 3 instead of Operand 2 so needs special casing in the disassembler and code emitter. Ultimately, should pass this information from tablegen

llvm-svn: 142105

llvm-svn: 142098

llvm-svn: 142097

Add support for X86 blsr, blsmsk, and blsi instructions. Required extra work because these are the first VEX encoded instructions to use the reg field as an opcode extension.

llvm-svn: 142082

Pass the correct jobs and threads information to the builder.
We were underutilizing the number of jobs and threads specified
by the user.

llvm-svn: 141977

Bit just a bit more verbose about what's going on.  Print options
to make to aid debugging.

llvm-svn: 141976

Add a --no-install option to skip installing components.  This
speeds up the develop/test cycle.

llvm-svn: 141975

And a --no-gcc option to skip dragonegg and gcc builds.
This greatly speeds up the develop/test cycle.

TableGen infers unmodeled side effects on instructions without a
pattern.  Fix some instruction definitions where that was overlooked.

Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

Fix disassembling of popcntw. Also remove some code that says it accounts for 64BIT_REXW_XD not existing, but it does exist.

This should unbreak the picky buildbots.

llvm-svn: 141575

The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.

Add a test case for xorps which has a very high opcode that exposes this
problem.

Multidefs are a bit unwieldy and incomplete.  Remove them in favor of
another mechanism, probably for loops.

Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.
