MIR Serialization: print and parse LLVM IR using MIR format.

This commit is the initial commit for the MIR serialization project.
It creates a new library under CodeGen called 'MIR'. This new
library adds a new machine function pass that prints out the LLVM IR
using the MIR format. This pass is then added as a last pass when a
'stop-after' option is used in llc. The new library adds the initial
functionality for parsing of MIR files as well. This commit also
extends the llc tool so that it can recognize and parse MIR input files.

9 years ago[mips] Correct and improve special-case shuffle instructions.
Daniel Sanders [Tue, 19 May 2015 12:24:52 +0000 (12:24 +0000)]
[mips] Correct and improve special-case shuffle instructions.

Summary:
The documentation writes vectors highest-index first whereas LLVM-IR writes
them lowest-index first. As a result, instructions defined in terms of
left_half() and right_half() had the halves reversed.

In addition to correcting them, they have been improved to allow shuffles
that use the same operand twice or in reverse order. For example, ilvev
used to accept masks of the form:
  <0, n, 2, n+2, 4, n+4, ...>
but now accepts:
  <0, 0, 2, 2, 4, 4, ...>
  <n, n, n+2, n+2, n+4, n+4, ...>
  <0, n, 2, n+2, 4, n+4, ...>
  <n, 0, n+2, 2, n+4, 4, ...>

One further improvement is that splati.[bhwd] is now the preferred instruction
for splat-like operations. The other special shuffles are no longer used
for splats. This lead to the discovery that <0, 0, ...> would not cause
splati.[hwd] to be selected and this has also been fixed.

This fixes the enc-3des test from the test-suite on Mips64r6 with MSA.

Michael Kuperstein [Tue, 19 May 2015 11:06:56 +0000 (11:06 +0000)]
[X86] ABI change for x86-32: pass 3 vector arguments in-register instead of 4, except on Darwin.

This changes the ABI used on 32-bit x86 for passing vector arguments.
Historically, clang passes the first 4 vector arguments in-register, and additional vector arguments on the stack, regardless of platform. That is different from the behavior of gcc, icc, and msvc, all of which pass only the first 3 arguments in-register.
The 3-register convention is documented, unofficially, in Agner's calling convention guide, and, officially, in the recently released version 1.0 of the i386 psABI.

Darwin is kept as is because the OS X ABI Function Call Guide explicitly documents the current (4-register) behavior.

This fixes PR21510
