2009-01-12Rename getABITypeSize to getTypePaddedSize, asDuncan Sands
suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62099 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12Add DwarfWriter interface to mainipulate source location info.Devang Patel
( May be this info should be directly handled by the dwarf writer ? ) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62096 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-12Remove some dead code from the days llvm had type planes.Rafael Espindola
There might be more dead code, but with llvm-gcc bootstrap broken on linux x86-64 it is had to test :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62088 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12Fix PR3241: Currently EmitCopyFromReg emits a copy from the physical ↵Evan Cheng
register to a virtual register unless it requires an expensive cross class copy. That means we are only treating "expensive to copy" register dependency as physical register dependency. Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62074 91177308-0d34-0410-b5e6-96231b3b80d8

not a random piece of it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62066 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-11Increase default inlining aggressiveness in partialDale Johannesen
compensation for turning off gcc's inliner. This gets us closer to the amount of inlining we were getting before. It is not a win on everything, of course, but seems to gain overall. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62058 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-11simplify CallSite helper class to not consult the Instruction'sGabor Greif
opcode on each delegation. Instead the information is cached on construction and the cached flag used thereafter. Introduced two predicates: isCall and isInvoke. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62055 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-11Duncan is nervous about undefinedness of % with negatives. I'mChris Lattner
not thrilled about 64-bit % in general, so rewrite to use * instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62047 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-11do not generated GEPs into vectors where they don't already exist.Chris Lattner
We should treat vectors as atomic types, not like arrays. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62046 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-11Make a couple of cleanups to the instcombine bitcast/gep Chris Lattner
canonicalization transform based on duncan's comments: 1) improve the comment about %. 2) within our index loop make sure the offset stays within the *type size*, instead of within the *abi size*. This allows us to reason explicitly about landing in tail padding and means that issues like non-zero offsets into [0 x foo] types don't occur anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62045 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08Do not inline functions with (dynamic) alloca intoDale Johannesen
functions that don't already have a (dynamic) alloca. Dynamic allocas cause inefficient codegen and we shouldn't propagate this (behavior follows gcc). Two existing tests assumed such inlining would be done; they are hacked by adding an alloca in the caller, preserving the point of the tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61946 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08ValueTracker can't assume that an alloca with no specified alignment Chris Lattner
will get its preferred alignment. It has to be careful and cautiously assume it will just get the ABI alignment. This prevents instcombine from rounding up the alignment of a load/store without adjusting the alignment of the alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61934 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08This implements the second half of the fix for PR3290, handlingChris Lattner
loads from allocas that cover the entire aggregate. This handles some memcpy/byval cases that are produced by llvm-gcc. This triggers a few times in kc++ (with std::pair<std::_Rb_tree_const_iterator <kc::impl_abstract_phylum*>,bool>) and once in 176.gcc (with %struct..0anon). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61915 91177308-0d34-0410-b5e6-96231b3b80d8
