Dale Johannesen 0192552340 Don't count DebugInfo instructions in another limit 
(lest they affect codegen).

Dale Johannesen fcf4ecec45 Testcase for line number sinking in InstCombine. 
llvm-svn: 65911
 2009-03-03 01:10:01 +00:00
Dale Johannesen e1bb2f86f9 When sinking an insn in InstCombine bring its debug 
info with it.
Don't count debug info insns against the scan maximum
in FindAvailableLoadedValue (lest they affect codegen).

Devang Patel d50ebbdf3f If branch conditions' one successor is dominating another non-latch successor then this loop's iteration space can not be restricted. In this example block bb5 is always executed.

Bob Wilson 85cefe8567 Generalize BuildVectorSDNode::isConstantSplat to use APInts and handle 
arbitrary vector sizes.  Add an optional MinSplatBits parameter to specify
a minimum for the splat element size.  Update the PPC target to use the
revised interface.

 2009-03-02 23:15:59 +00:00
Bill Wendling bf5d827194 Add a "-gcc-tool-args" option. This option acts like the "-tool-args" option, 
but passes the arguments to the "gcc" invocation instead of to the "llc"
invocation.

Devang Patel 49d64927e1 Remove all dbg symobls, including those with circular references. 
This is ugly, but I can't figure out a quick way out of this.

Duncan Sands d16340c846 Try to make the meaning of 'nocapture' a bit clearer. I 
commented out the line about simplifylibcalls because I
think this doesn't work in the release (it was fixed in
svn after the release branched).

Gabor Greif 1ab00bf883 Declare Sentinel fragments as mutable to get rid 
of some pointless casting. This fragment logically
does not belong to ilist anyway, but to "ghostly"
NodeType.

Mikhail Glushenkov ecfab627fd Move code from Main.cpp to the include dir. 
User drivers based on llvmc must all share the initialization code.
Putting main() into libCompilerDriver is not a very good idea IMO (and ld gave
me some strange EH-related error anyway).

Mikhail Glushenkov 931d4521c3 Reorganize llvmc code. 
Move the code from 'llvmc/driver' into a new CompilerDriver library, and change
the build system accordingly. Makes it easier for projects using LLVM to build
their own llvmc-based drivers.

Tested with objdir != srcdir.

Nate Begeman a9e981225e Fix a problem with DAGCombine on 64b targets where folding 
extracts + build_vector into a shuffle would fail, because the
type of the new build_vector would not be legal.  Try harder to
create a legal build_vector type.  Note: this will be totally 
irrelevant once vector_shuffle no longer takes a build_vector for
shuffle mask.
