Sean Callanan b60b0bc47e Enabled disassembler support for AVX instructions 
in the instruction tables and fixed a few bugs that
were causing decode conflicts.  Rudimentary tests
are coming up in the next patch.

llvm-svn: 127646
 2011-03-15 01:28:15 +00:00
Sean Callanan c3fd523731 X86 table-generator and disassembler support for the AVX 
instruction set.  This code adds support for the VEX prefix
and for the YMM registers accessible on AVX-enabled
architectures.  Instruction table support that enables AVX
instructions for the disassembler is in an upcoming patch.

Andrew Trick a34f1b1f10 Remove getMinusSCEVForExitTest(). 
This function performed acrobatics to prove no-self-wrap, which we now
have for free.

Johnny Chen 7a2873dfbe Fixed an ARM disassembler bug where it does not handle STRi12 correctly because an extra 
register operand was erroneously added.  Remove an incorrect assert which triggers the bug.

Ken Dyck 1c80fd1346 Introduce a CharUnits FieldOffsetInChars variable in AppendField() to 
replace some uses of FieldOffsetInBytes. The remaining uses of
FieldOffsetInBytes will be replaced once NextFieldOffsetInBytes is converted
to CharUnits. No change in functionality intended.

Bill Wendling 5c25a92011 There are some situations which can cause the URoR hack to infinitely recurse 
and then go kablooie. The problem was that it was tracking the PHI nodes anew
each time into this function. But it didn't need to. And because the recursion
didn't know that a PHINode was visited before, it would go ahead and call
itself.

There is a testcase, but unfortunately it's too big to add. This problem will go
away with the EH rewrite.

Argyrios Kyrtzidis 669b0b1521 Stop leaking file descriptors. 
After the open+fstat optimization, files were already opened for FileManager::getBufferForFile() and we closed them after reading them.
The problem was that when -working-directory was passed, the code path that actually reuses & closes the already opened file descriptor
was not followed.

Jim Grosbach 3af6fe66b9 Clean up ARM tail calls a bit. They're pseudo-instructions for normal branches. 
Also more cleanly separate the ARM vs. Thumb functionality. Previously, the
encoding would be incorrect for some Thumb instructions (the indirect calls).

Bill Wendling e1fd78f2bc Generate a VTBL instruction instead of a series of loads and stores when we 
can. As Nate pointed out, VTBL isn't super performant, but it *has* to be better
than this:

_shuf:
@ BB#0:       @ %entry
  push        {r4, r7, lr}
  add         r7, sp, #4
  sub         sp, #12
  mov         r4, sp
  bic         r4, r4, #7

  vmov        d16, r0, r1

  vst1.8      {d16[3]}, [r2]
  vldr.64     d16, [sp]
  vmov        r0, r1, d16
  mov         sp, r4
  pop         {r4, r7, pc}

The "illegal" testcase in vext.ll is no longer illegal.

John McCall e2eb807601 Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort() 
doesn't return, so just go back to using the old runtime function instead
of trying to use abort() when __builtin_unreachable (or an equivalent) isn't
supported.

Renato Golin 4b6ae939ca This patch is a big refactoring of llvm-diff. It doesn't add new features, but it re-organizes the old features, so I can insert the MetadataEngine to use the same infrastructure.

Douglas Gregor 88764cf822 When synthesizing a label declaration based on a goto statement that 
cannot yet be resolved, be sure to push the new label declaration into
the right place within the identifier chain. Otherwise, name lookup in
C++ gets confused when searching for names that are lexically closer
than the label. Fixes PR9463.
