Jeffrey Yasskin aba6ea8254 Reapply r97788 to free MDNodes when the LLVMContext is destroyed. It 
bootstraps llvm-gcc this time.

Jeffrey Yasskin 37a0372fc4 Roll r97906 forward again, without double-deleting CompileUnit::IndexTyDie.

Tobias Grosser 62892a8680 Add findNearestCommonDominator() for PostDominators. 
Add a missing interface to be able to call findNearestCommonDominator
for a PostDominanceTree. The function itself is already implemented in
DominatorTreeBase. The interface however was only added to the
DominatorTree class, but not the PostDominatorClass.

Kovarththanan Rajaratnam 752a124aeb Rename to addPPCallbacks since we're effectively adding a callback and maybe chaining it to an existing one

 2010-03-07 07:20:49 +00:00
Kovarththanan Rajaratnam 981a6a110e Don't assert if PP already contains a valid PP callback. The PP can handle multiple callbacks (using PPChainedCallbacks)

Chris Lattner b9071a2d5d teach tblgen to be more aggressive when factoring CheckType nodes. 
Now it will factor things like this:

CheckType i32
  ...
CheckOpcode ISD::AND
  CheckType i64
  ...

into:

SwitchType:
  i32: ...
  i64:
    CheckOpcode ISD::AND
    ...

This shrinks hte table by a few bytes, nothing spectacular.

llvm-svn: 97906
 2010-03-07 06:55:35 +00:00
Chris Lattner 9c791d872a add some helper functions and implement isContradictory 
for CheckValueTypeMatcher.  The isContradictory implementation
helps us factor better, shrinking x86 table from 79144 -> 78896
bytes.

Eli Friedman b632e30e41 Fix for PR6294: we should only delay recording nested dynamic classes if they 
are lexically nested.  Othewise, we never end up recording semantically nested
classes.

Douglas Gregor 577cf97cf3 Don't turn off mangling in implicitly extern "C" system headers. GCC 
doesn't do this on any of the major platforms, and we don't really
support any of the platforms that do (nor will we actually handle
those headers well). Fixes PR6217; see PR6530 for details on what we
would need to do to support these platforms.

Chris Lattner 8341c390aa on both the mac and linux, /usr/local/include is treated 
as a "C++ Friendly" system header directory.  This fixes
PR6523.

llvm-svn: 97885
 2010-03-06 19:38:10 +00:00
Anton Korobeynikov d5e3fd6dc8 Lower dynamic stack allocation on mingw32 to separate instruction. 
We cannot use a normal call here since it has extra unmodelled side
effects (it changes stack pointer). This should fix PR5292.

llvm-svn: 97884
 2010-03-06 19:32:29 +00:00
Chris Lattner 4c1e4db3ff make APFloat::toString be const.

Anton Korobeynikov 6f5523aa8b Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though). 
This fixes PR6349

before we try to optimize.

Eric Christopher a7fb58f5f5 Migrate _chk call lowering from SimplifyLibCalls to InstCombine. Stub 
out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

Jim Grosbach 24c9b550b2 Thumb1 epilogue code generation needs to take into account that callee-saved 
registers may be restored via a pop instruction, not just a tRestore.
This fixes nightly test 471.omnetep for Thumb1.

Eric Christopher d8b43d0e59 Temporarily revert: 
Log:
Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.

Modified:
   llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp
   llvm/trunk/test/Transforms/InstCombine/objsize.ll

It appears to be causing swb and nightly test failures.
