Eli Friedman 0318036c4d Make the disassembler able to disassemble a bunch of instructions with names in the TableGen files containing "64" on x86-32. This includes a bunch of x87 instructions, like fld, and a bunch of SSSE3 instructions on MMX registers like pshufb. Part of PR8873.

Andrew Trick c591f3afc3 indvars: fix a pass-sensitivity issue that would hit the SCEVExpander 
assertion I added in r135333. Check for the existence of a preheader
before expanding a recurrence.

Andrew Trick 9ea55dc2d6 indvars: remove ExprToIVMap because it won't be needed by LFTR.

 2011-07-16 01:06:48 +00:00
Andrew Trick 244e2c3e82 Fix SCEVEXpander to handle arbitrary phi expansion. Includes two 
related bug fixes and corresponding assertions for uninitialized data
and missing NULL check. Test cases will be included with the new LFTR.

Jakob Stoklund Olesen 37e3a13931 He said *before* the last split point. 
This should unbreak the build-self-4-mingw32 tester. I have a very
complicated test case that I will try to clean up.

Chris Lattner 8b4cf5e8a2 fix rdar://9776316 - type remapping needed for inline asm blobs, 
fixing some objc llvm-test crashes with LTO.

Owen Anderson d57a049e5c Get rid of the separate opcodes for the Darwin versions of tBL, tBLXi, and tBLXr, using pseudo-instructions to lower to the single final opcode. Update the ARM disassembler for this change. 
llvm-svn: 135319
 2011-07-15 22:49:31 +00:00
Dan Gohman e49e74261a Delete LegalizeDAG's own version of isTypeLegal and getTypeAction 
and just use the ones from TargetLowering directly.

llvm-svn: 135318
 2011-07-15 22:39:09 +00:00
Bruno Cardoso Lopes 8df9cfc279 Fix a couple of things: 
1) Make non-legal 256-bit loads to be promoted to v4i64. This lets us
canonize the loads and handle things the same way we use to handle
for 128-bit registers. Despite of what one of the removed comments
explained, the load promotion would not mess with VPERM, it's only a
matter of doing the appropriate bitcasts when this instructions comes
to be introduced. Also make LOAD v8i32 legal.

2) Doing 1) exposed two bugs:
- v4i64 was being promoted to itself for several opcodes (introduced
in r124447 by David Greene) causing endless recursion and the stack to
explode.
- there was no support for allOnes BUILD_VECTORs and ANDNP would fail to
match because it was generating early target constant pools during
lowering.

3) The testcases are already checked-in, doing 1) exposed the
bugs in the current testcases.

4) Tidy up code to be more clear and explicit about AVX.

 2011-07-15 22:24:33 +00:00
Bruno Cardoso Lopes 1fe1377e65 Add a few patterns for 256-bit bitcasts. No testcases now, they are 
comming together with other tests.

Dan Gohman 8c5ca645ce Delete an unused variable and a redundant assert.

 2011-07-15 22:19:02 +00:00
Jakob Stoklund Olesen 795da1c108 Extract parts of RAGreedy::splitAroundRegion as SplitKit methods. 
This gets rid of some of the gory splitting details in RAGreedy and
makes them available to future SplitKit clients.

Slightly generalize the functionality to support multi-way splitting.
Specifically, SplitEditor::splitLiveThroughBlock() supports switching
between different register intervals in a block.

not isEquality().

Owen Anderson 454e1c7abb Remove VMOVDneon and VMOVQ, which are just aliases for VORR. This continues to simplify the path towards an auto-generated disassembler.

Benjamin Kramer f6f3e81c07 ObjectFile: Add a method to check whether a section contains a symbol. 
- No ELF or COFF implementation yet, I don't have a way to test that.
  Should be straightforward to add though.

Chad Rosier a7ff54351a Disable loop idiom recognition of memset/memcpy if the function being compiled 
is named after a common idiom (i.e., memset/memcpy).  Otherwise, we can run into 
infinite recursion.  Ideally, the user should use the correct -fno-builtin flag,
but in case they don't we should play nicely.

Owen Anderson 9cf6f8a9b8 Remove unnecessary duplicate instruction definitions that simply overloaded the type of VEXT. This can be achieved with a Pat definition, and is much more disassembler friendly.

NAKAMURA Takumi cb1a888fde Eliminate "const" from extern const to fix breakeage since r135184 on msvc. 
MSVC decorates (and distinguishes) "const" in mangler. It brought linkage error between "extern const" declarations and definitions.

Frits van Bommel f8bf4c213a In Twine::str(), if the Twine stores only a std::string, just return a direct copy of that instead of first copying to a SmallString and converting that to a std::string. Also fix some indentation.

Chandler Carruth 1bf4a30d4d Explicitly cast the second argument to unsigned in order to select the 
desired overload.

This is a bit of a hackish workaround to fix the compile after r135259.
Let me know if there is a better approach.

Chris Lattner af1783f987 remove the old and dangerous uncheckedReplaceAllUsesWith method, 
which was just replaceAllUsesWith without some assertions.  It was
needed back when type refinement was alive.
