the last compiler built for the previous flavour is used for the next,
for example the Debug clang compiler was being used for the initial build
of the Release LLVM.  Flavors should be independent of each other.  This
especially matters if the compiler built for the previous flavour doesn't
actually work!

In fact this commit is not intended to change anything unless you
use one of the new command line flags.

Duncan pointed out that sometimes CC and CXX are used to specify the compiler. Also that the configure script takes care of finding an appropriate compiler if one's not specified.

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.

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

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.

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

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.
