Wesley Peck 7d99b5b651 MBlaze delay slot filler was not capable of using ADDK and variants to fill delay slots. This broke several test cases when 121649 was committed. This fixes the regression.

Wesley Peck 632b5926d3 The ADD and ADDK (and all variants) instructions where flip-flopped in the MBlaze backend. This bug fix makes 64-bit math work on the MBlaze backend.

Tobias Grosser f3e1ada522 Remove useless dynamic_cast<>(). 
Thanks Peter for pointing me to something that should have never been
committed to the llvm code base.

Peter Collingbourne 5be5391df0 Regen configure 
llvm-svn: 121646
 2010-12-12 21:42:01 +00:00
Peter Collingbourne 607e0bd7c7 Fix paths; AutoRegen.sh changes its current working directory to be the 
autoconf directory, but these paths need to be relative to the main
source directory.  Patch originally by Dan Gohman, r67655.

Also, cause configure.ac to find absolute paths to LLVM source and
object trees.   Together, fixes PR1220.

Wesley Peck 968bc26a0a 1. Change MBlaze indirect branches to use absolute branch BRALD instead of pc relative branch BRLD. 
2. Make sure that the MBlaze stack is aligned to 4-byte boundaries.
3. Determine frame indexes that should be placed in the callers stack frame, as per the MBlaze ABI, and place them in the correct locations.

Duncan Sands d2e70b5442 Catch attempts to remove a deleted node from the CSE maps. Better to 
catch this here rather than later after accessing uninitialized memory
etc.  Fires when compiling the testcase in PR8237.

Benjamin Kramer c4169cebe3 Generalize the and-icmp-select instcombine further by allowing selects of the form 
(x & 2^n) ? 2^m+C : C

we can offset both arms by C to get the "(x & 2^n) ? 2^m : 0" form, optimize the
select to a shift and apply the offset afterwards.

Benjamin Kramer c8b035d006 Factor the (x & 2^n) ? 2^m : 0 instcombine into its own method and generalize it 
to catch cases where n != m with a shift.

Jakob Stoklund Olesen adecb5e82c Force the greedy register allocator to always use the inline spiller. 
Soon, RegAllocGreedy will start splitting live ranges, and then deferred
spilling won't work anyway.

 2010-12-10 22:54:44 +00:00
Jakob Stoklund Olesen 276445f3b8 Rip out live range splitting support from the inline spiller. 
The spiller should only spill. The register allocator will drive live range
splitting, it has the needed information about register pressure and
interferences.

llvm-svn: 121508
 2010-12-10 19:40:47 +00:00
Dan Gohman 4bd64fa805 Introduce a new PartialAlias response for AliasAnalysis. For most 
AliasAnalysis consumers, PartialAlias will be treated as MayAlias.

For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
PartialAlias will be used to indicate that the query should terminate,
even though it didn't reach MustAlias or NoAlias.
