Bob Wilson d561daf520 Update MachineSSAUpdater with the same changes I made for the IR-level 
SSAUpdater.  I'm going to try to refactor this to share most of the code
between them.

Evan Cheng ed69b382ea - Move TargetLowering::EmitTargetCodeForFrameDebugValue to TargetInstrInfo and rename it to emitFrameIndexDebugValue. 
- Teach spiller to modify DBG_VALUE instructions to reference spill slots.

Dale Johannesen 582565e991 Stop abusing EmitInstrWithCustomInserter for target-dependent 
form of DEBUG_VALUE, as it doesn't have reasonable default
behavior for unsupported targets.  Add a new hook instead.
No functional change.

preferred alignment unless they were common or some other special
case.

Dan Gohman a1c94049c2 Fix an autoconf bug: The second argument to AC_LANG_PROGRAM is code that 
gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail, 
leaving their options disabled.

This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.

This also includes a regenerated configure, as the diff is small and telling.

Dan Gohman 283a350f4d PHI nodes also do not necessarily return trap with a trap operand.

Nick Lewycky 20f5e974e4 Use provided llvm-defined variables instead of twisting user-controlled knobs. 
No visible change.

 2010-04-24 05:07:24 +00:00
Nick Lewycky 3afcd7cd80 Don't touch CXXFLAGS. If it's set in the environment then sub-makes will see 
the variable that we set as though it came from the user. Fixes PR6835.

Evan Cheng a02d0e7d6b Avoid promoting a i16 node if it would eliminate a (store (op (load))) opportunity. 
llvm-svn: 102237
 2010-04-24 04:44:57 +00:00
Evan Cheng 0abb54d631 When a load operand is promoted to an extload, replace other uses with uses of extload result truncated.

Dan Gohman 534ba376f6 Generalize LSR's OptimizeMax to handle the new kinds of max expressions 
that indvars may use, now that indvars is recognizing le and ge loops.

llvm-svn: 102235
 2010-04-24 03:13:44 +00:00
Dan Gohman f33bac3afe ScalarEvolution support for <= and >= loops. 
Also, generalize ScalarEvolutions's min and max recognition to handle
some new forms of min and max that this change makes more common.

llvm-svn: 102232
 2010-04-24 01:34:53 +00:00
Dan Gohman 48ff3cf63b Add a new utility function SimplifyICmpOperands. Much of this code is 
refactored out of ScalarEvolution::isImpliedCond, which will be updated
to use this new utility routine soon.

Dan Gohman 5544b0c588 Apply a fix for a vector setcc dagcombine from Jan Sjodin. No

Sean Callanan 85d70594f0 Fixes to edis that mark x86 call targets as 
memory operands rather than immediate operands.

Stuart Hastings c8b2fc0909 Per Chris, fuse four trivial tests using grep (r102199) into one that uses FileCheck.

Chris Lattner d3b361d1b6 enable my inliner change: add newly devirtualized call sites to 
the worklist, making them inline candidates.

llvm-svn: 102213
 2010-04-23 21:16:07 +00:00
Dan Gohman e1931fa676 Change TargetData's algorithm for computing defualt vector type 
alignment to match what's used in clang and GCC for __alignof, rather
than trying to guess what Legalize is going to be doing.

llvm-svn: 102197
 2010-04-23 18:38:40 +00:00
Chris Lattner c691de3b4e switch InlineInfo.DevirtualizedCalls's list to be of WeakVH. 
This fixes a bug where calls inlined into an invoke would get
changed into an invoke but the array would keep pointing to
the (now dead) call.  The improved inliner behavior is still
disabled for now.

llvm-svn: 102196

Chris Lattner 6f41ef9d31 testcase for the bug that required a patch to be reverted.

Chris Lattner 8c56254096 fix callgraph dump to not print 0x0x1234 for nodes. 
Add the instruction pointer value for debuggability.  
We now get dump output that looks like this:

Call graph node for function: 'f1'<<0x1017086b0>>  #uses=1
  CS<0x1017046f8> calls external node

Call graph node for function: '_ZNSt6vectorIdSaIdEEC1EmRKdRKS0_'<<0x1017086f0>>  #uses=1
  CS<0x0> calls external node

Call graph node for function: 'f4'<<0x1017087a0>>  #uses=1
  CS<0x101708c88> calls function 'f3'

Sean Callanan 62232d90cf Fixed EDOperand to use the operand type, not the 
flags, to determine whether or not the operand is
a memory operand.

llvm-svn: 102158
 2010-04-23 01:56:36 +00:00
Dan Gohman 997bbc54d6 Fix LSR to tolerate cases where ScalarEvolution initially 
misses an opportunity to fold add operands, but folds them
after LSR has separated them out. This fixes rdar://7886751.

llvm-svn: 102157
 2010-04-23 01:55:05 +00:00
Dan Gohman ff3174e97f When it doesn't matter whether zero or sign extension is used, 
use ScalarEvolutions "any" extend function.
