One too many )'s breaks 'make clean' with certain versions of make. This fixes PR1927 git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_22@46248 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the failures in the PPC JIT by marking relocation entries for external symbols (e.g. 'fmod') as needing a stub. This regression was introduced by Evan's jit patch here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071231/056749.html With this fixed, the two ExecutionEngine failures are passing on ppc, and the ppc jit works on freebench and olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_22@46225 91177308-0d34-0410-b5e6-96231b3b80d8

Need to handle any 'nest' parameter before integer parameters, since otherwise it won't be passed in the right register.

Revert the part of 45849 that treated weak globals as weak globals rather than commons. While not wrong, this change tickled a latent bug in Darwin's strip, so revert it for now as a workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_22@46168 91177308-0d34-0410-b5e6-96231b3b80d8

spilled and the spill is its kill. However, if the local allocator has determined the register has not been modified (possible when its value was reloaded), it would not issue a restore.

2008-01-16Fixes a nasty dag combiner bug that causes a bunch of tests to fail at -O0.Evan Cheng
It's not safe to use the two value CombineTo variant to combine away a dead load. e.g. v1, chain2 = load chain1, loc v2, chain3 = load chain2, loc v3 = add v2, c Now we replace use of v1 with undef, use of chain2 with chain1. ReplaceAllUsesWith() will iterate through uses of the first load and update operands: v1, chain2 = load chain1, loc v2, chain3 = load chain1, loc v3 = add v2, c Now the second load is the same as the first load, SelectionDAG cse will ensure the use of second load is replaced with the first load. v1, chain2 = load chain1, loc v3 = add v1, c Then v1 is replaced with undef and bad things happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46099 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Trampoline support for x86-64. This looks likeDuncan Sands
it should work, but I have no machine to test it on. Committed because it will at least cause no harm, and maybe someone can test it for me! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46098 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-16My previous commit had an incomplete message, it should have been:Chris Lattner
make the 'fp return in ST(0)' optimization smart enough to look through token factor nodes. THis allows us to compile testcases like CodeGen/X86/fp-stack-retcopy.ll into: _carg: subl $12, %esp call L_foo$stub fstpl (%esp) fldl (%esp) addl $12, %esp ret instead of: _carg: subl $28, %esp call L_foo$stub fstpl 16(%esp) movsd 16(%esp), %xmm0 movsd %xmm0, 8(%esp) fldl 8(%esp) addl $28, %esp ret Still not optimal, but much better and this is a trivial patch. Fixing the rest requires invasive surgery that is is not llvm 2.2 material. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46054 91177308-0d34-0410-b5e6-96231b3b80d8
