Mon P Wang f67448adf8 Added option to enable generating less precise mad (multiply addition) 
for those architectures that support the instruction.

Dan Gohman 76402b9a3d The last use in a block that doesn't have successors 
(return or unreachable) is a kill.

Evan Cheng 6d6647c7b3 Fix typo's.

 2009-03-20 00:14:09 +00:00
Sebastian Redl 8d5baa09f8 Fix the Win32 VS2008 build: 
- Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

 2009-03-19 23:26:52 +00:00
Evan Cheng 1361cbbb0b Added MachineInstr::isRegTiedToDefOperand to check for two-addressness. 
llvm-svn: 67335
 2009-03-19 20:30:06 +00:00
Evan Cheng 05799db963 More makefile changes to allow dejagnu tests to pass when system tools default to a different target from the llvm configuration (e.g. 64-bit gcc and 32-bit llvm). 
llvm-svn: 67334

Dan Gohman 1026a8001f SADDO and UADDO are commutative.

Dale Johannesen 2050968df9 Clear the cached cost when removing a function in 
the inliner; prevents nondeterministic behavior
when the same address is reallocated.
Don't build call graph nodes for debug intrinsic calls;
they're useless, and there were typically a lot of them.

 2009-03-19 18:03:56 +00:00
Dan Gohman 37061eef5d Add a liveness analysis pass for LLVM IR values. This computes 
the set of blocks in which values are used, the set in which
values are live-through, and the set in which values are
killed. For the live-through and killed sets, conservative
approximations are used.

Dale Johannesen e4f361212b Fix comment typo. 
llvm-svn: 67307
 2009-03-19 17:23:29 +00:00
Dale Johannesen 52bc2aac8a This pass keeps a map of Instructions to Rank numbers, 
and was deleting Instructions without clearing the
corresponding map entry.  This led to nondeterministic
behavior if the same address got allocated to another
Instruction within a short time.

 2009-03-19 17:22:53 +00:00
Ted Kremenek dd03b5bb63 Fix regression in 'tblgen -gen-clang-diags-defs': Emit the diagnostic kind instead of "DIAGNOSTICCONTROLLED". 
llvm-svn: 67305
 2009-03-19 17:18:09 +00:00
Chris Lattner 58bd3dccf9 Fix PEI to not walk off the start of a block when an updated instruction 
is the first in its block.  This is PR3842.

llvm-svn: 67304
 2009-03-19 17:15:43 +00:00
Duncan Sands 8208465036 Fix comment typo.

Nick Lewycky 063699af70 Fix a couple glaring whitespace issues. This file isn't internally consistent 
either.

Nick Lewycky bfd4ad67c7 Remove strange extra semicolons. 
llvm-svn: 67287
 2009-03-19 05:51:39 +00:00
Nate Begeman dbe3f77f5b Add support to tablegen for naming the nodes themselves, not just the operands, 
in selectiondag patterns.  This is required for the upcoming shuffle_vector rewrite,
and as it turns out, cleans up a hack in the Alpha instruction info.

Ted Kremenek 4724b8262f tblgen -gen-clang-diags-options: Output OptionTable entries in lexicographic 
order.

llvm-svn: 67244
 2009-03-18 21:36:46 +00:00
Ted Kremenek bf76c6d971 'tblgen -gen-clang-diags-options' now outputs the OptionTable: 
static const WarningOption OptionTable[] = {
    {"unused-macros", DIAGS(UnusedMacrosDiags)}
    ...
  };

This table is not yet properly sorted.

llvm-svn: 67242
 2009-03-18 21:28:47 +00:00
Ted Kremenek 4a330b7ec1 Add another Clang TableGen-backend (-gen-clang-diags-options) for emitting 
declarations for controlling groups of warnings. Currently this transforms:

  def UnusedMacrosDiags : Option<"unused-macros", [pp_macro_not_used]>;
  
into:

  static const diag::kind UnusedMacrosDiags[] = { diag::pp_macro_not_used };

Chris Lattner 0f6dc78cfe include the null at the end of a memorybuffer as part of the buffer. 
This allows tblgen to handle include "foo.td" when the quote is exactly
the last character in a file.  rdar://6695728

Bill Wendling 7b06cbe6d4 These tests are now passing on Darwin because of r67139.

 2009-03-18 17:45:11 +00:00
Chris Lattner 514fc5b143 aha, DAE does have to think about PHI nodes. Many thanks to "Dr Evil" (aka Duncan) 
for pointing this out :)

llvm-svn: 67212
 2009-03-18 16:48:45 +00:00
Chris Lattner 595923ff75 Fix PR3826 - InstComb assert with vector shift, by not calling ComputeNumSignBits on a vector. 
llvm-svn: 67211
 2009-03-18 16:32:19 +00:00
Chris Lattner ab8022055a add an assertion to make it clear that PHI nodes are not allowed.

Zhou Sheng 4e2af3cb55 Explicitly check for StoreInst, do not lose the chance to delete 
unused loads or bitcasts.

llvm-svn: 67202
 2009-03-18 12:48:48 +00:00
Zhou Sheng 05bea906c1 Revert my previous change on Local.cpp, instead, fix the bug on scalarrepl. 
If the instruction has no users, it is also not only used by debug info 
and should not be deleted.

llvm-svn: 67194
 2009-03-18 10:13:08 +00:00
Rafael Espindola d2b64fc65b Add -relocation-model=pic so that the test works 
both in Linux and Darwin.

llvm-svn: 67191
 2009-03-18 09:38:28 +00:00
Zhou Sheng 64a6a092b1 Fix a bug. 
If I->use_empty(), this method should return false.

llvm-svn: 67180
 2009-03-18 07:56:13 +00:00
Mon P Wang 32c8074be6 Added missing support for widening when splitting an unary op (PR3683) 
and expanding a bit convert (PR3711).  In both cases, we extract the
valid part of the widen vector and then do the conversion.

llvm-svn: 67175
 2009-03-18 06:24:04 +00:00
Evan Cheng 8df898917f Add another test case for r64440. 
llvm-svn: 67156
 2009-03-18 02:43:01 +00:00
Evan Cheng 110377c669 xfail these tests for now. 
llvm-svn: 67143
 2009-03-18 00:44:45 +00:00
Chris Lattner a6bed3e950 Disable the "call to immediate" optimization on x86-64. It is 
not safe in general because the immediate could be an arbitrary
value that does not fit in a 32-bit pcrel displacement.  
Conservatively fall back to loading the value into a register
and calling through it.

We still do the optzn on X86-32.

llvm-svn: 67142
 2009-03-18 00:43:52 +00:00
Chris Lattner a15ce21135 Fix PR3807 by inserting 'insertelement' instructions in the normal dest of 
an invoke instead of after the invoke (in its block), which is invalid.

llvm-svn: 67139
 2009-03-18 00:31:45 +00:00
Bill Wendling 4eaeb4ef22 A more proper -mtriple. 
llvm-svn: 67138
 2009-03-18 00:19:44 +00:00
Bill Wendling 3aad86fa3f Temporary fix. I think Rafael wanted this to be Linux-only. 
llvm-svn: 67137
 2009-03-18 00:16:36 +00:00
Chris Lattner 42e9ca42ce LSR shouldn't ever try to hack on integer IV's larger than 64-bits. Right now 
it is not APInt clean, but even when it is it needs to be evaluated carefully
to determine whether it is actually profitable.

This fixes a crash on PR3806

Rafael Espindola 4606b12108 Don't force promotion of return arguments on the callee. 
Some architectures (like x86) don't require it.
This fixes bug 3779.

Daniel Dunbar 437b8a5ccc Add BUILTIN_EXPECT Support/Compiler macro. 
- Use for exceptional buffer conditions in raw_ostream:write to shave
   off a cycle or two.

 - Please rename if you have a better one.

 2009-03-17 21:15:18 +00:00
Chris Lattner 4359f3f26f this is apparently passing now. Evan/Dan, please check 
to see if this is producing the expected code or not, I'm
not sure what the test was intended to check.
