2008-01-19Need to handle any 'nest' parameter before integerDuncan Sands
parameters, since otherwise it won't be passed in the right register. With this change trampolines work on x86-64 (thanks to Luke Guest for providing access to an x86-64 box). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46192 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-18Fix a latent bug exposed by my truncstore patch. We compiled stfiwx-2.ll to:Chris Lattner
_test: fctiwz f0, f1 stfiwx f0, 0, r4 blr instead of: _test: fctiwz f0, f1 stfd f0, -8(r1) nop nop lwz r2, -4(r1) stb r2, 0(r4) blr The former is not correct (stores 4 bytes, not 1). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46161 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-17Revert the part of 45849 that treated weak globalsDale Johannesen
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/trunk@46147 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-17Forward progress: crtbegin.c now compiles successfully!Scott Michel
Fixed CellSPU's A-form (local store) address mode, so that all globals, externals, constant pool and jump table symbols are now wrapped within a SPUISD::AFormAddr pseudo-instruction. This now identifies all local store memory addresses, although it requires a bit of legerdemain during instruction selection to properly select loads to and stores from local store, properly generating "LQA" instructions. Also added mul_ops.ll test harness for exercising integer multiplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46142 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17This commit changes:Chris Lattner
1. Legalize now always promotes truncstore of i1 to i8. 2. Remove patterns and gunk related to truncstore i1 from targets. 3. Rename the StoreXAction stuff to TruncStoreAction in TLI. 4. Make the TLI TruncStoreAction table a 2d table to handle from/to conversions. 5. Mark a wide variety of invalid truncstores as such in various targets, e.g. X86 currently doesn't support truncstore of any of its integer types. 6. Add legalize support for truncstores with invalid value input types. 7. Add a dag combine transform to turn store(truncate) into truncstore when safe. The later allows us to compile CodeGen/X86/storetrunc-fp.ll to: _foo: fldt 20(%esp) fldt 4(%esp) faddp %st(1) movl 36(%esp), %eax fstps (%eax) ret instead of: _foo: subl $4, %esp fldt 24(%esp) fldt 8(%esp) faddp %st(1) fstps (%esp) movl 40(%esp), %eax movss (%esp), %xmm0 movss %xmm0, (%eax) addl $4, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46140 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17* Introduce a new SelectionDAG::getIntPtrConstant methodChris Lattner
and switch various codegen pieces and the X86 backend over to using it. * Add some comments to SelectionDAGNodes.h * Introduce a second argument to FP_ROUND, which indicates whether the FP_ROUND changes the value of its input. If not it is safe to xform things like fp_extend(fp_round(x)) -> x. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46125 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
2008-01-16make it more clear that this predicate only applies to scalar FP types.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46058 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16introduce a isTypeInSSEReg predicate, which allows us to simplifyChris Lattner
some code. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46055 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

2008-01-14Improve the FP stackifier to decide all on its own whether Chris Lattner
an instruction kills a register or not. This is cheap and easy to do now that instructions record this on their flags, and this eliminates the second pass of LiveVariables from the x86 backend. This speeds up a release llc by ~2.5%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45955 91177308-0d34-0410-b5e6-96231b3b80d8

Actually were not riding any arguments. Sadly there is no semantic spell checker that is going to safe you from such a mistake. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45868 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-11Improve tail call optimized call's argument lowering. Before thisArnold Schwaighofer
commit all arguments where moved to the stack slot where they would reside on a normal function call before the lowering to the tail call stack slot. This was done to prevent arguments overwriting each other. Now only arguments sourcing from a FORMAL_ARGUMENTS node or a CopyFromReg node with virtual register (could also be a caller's argument) are lowered indirectly. --This line, and those below, will be ignored-- M X86/X86ISelLowering.cpp M X86/README.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45867 91177308-0d34-0410-b5e6-96231b3b80d8
