2006-01-31Handle physreg input/outputs. We now compile this:Chris Lattner
int %test_cpuid(int %op) { %B = alloca int %C = alloca int %D = alloca int %A = call int asm "cpuid", "=eax,==ebx,==ecx,==edx,eax"(int* %B, int* %C, int* %D, int %op) %Bv = load int* %B %Cv = load int* %C %Dv = load int* %D %x = add int %A, %Bv %y = add int %x, %Cv %z = add int %y, %Dv ret int %z } to this: _test_cpuid: sub %ESP, 16 mov DWORD PTR [%ESP], %EBX mov %EAX, DWORD PTR [%ESP + 20] cpuid mov DWORD PTR [%ESP + 8], %ECX mov DWORD PTR [%ESP + 12], %EBX mov DWORD PTR [%ESP + 4], %EDX mov %ECX, DWORD PTR [%ESP + 12] add %EAX, %ECX mov %ECX, DWORD PTR [%ESP + 8] add %EAX, %ECX mov %ECX, DWORD PTR [%ESP + 4] add %EAX, %ECX mov %EBX, DWORD PTR [%ESP] add %ESP, 16 ret ... note the proper register allocation. :) it is unclear to me why the loads aren't folded into the adds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25827 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25774 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-29Legalize ConstantFP into TargetConstantFP when the target allows. ImplementChris Lattner
custom expansion of ConstantFP nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25772 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-29eliminate uses of SelectionDAG::getBR2Way_CCChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25767 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-28Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make itChris Lattner
faster. This cuts about 120 lines of code out of the legalizer (mostly code checking to see if operands have changed). It also fixes an ugly performance issue, where the legalizer cloned the entire graph after any change. Now the "UpdateNodeOperands" method gives it a chance to reuse nodes if the operands of a node change but not its opcode or valuetypes. This speeds up instruction selection time on kimwitu++ by about 8.2% with a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25746 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25737 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-28Several major changes:Chris Lattner
1. Pull out the expand cases for BSWAP and CT* into a separate function, reducing the size of LegalizeOp. 2. Fix a bug where expand(bswap i64) was wrong when i64 is legal. 3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be iterative. It now operates in a single pass over the nodes. 4. Simplify a LOT of code, with a net reduction of ~280 lines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25736 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-28Eliminate the need for ExpandOp to set 'needsanotheriteration', as it alreadyChris Lattner
relegalizes the stuff it returns. Add the ability to custom expand ADD/SUB, so that targets don't need to deal with ADD_PARTS/SUB_PARTS if they don't want. Fix some obscure potential bugs and simplify code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25732 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-28Instead of making callers of ExpandLibCall legalize the result, makeChris Lattner
ExpandLibCall do it itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25731 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-28Eliminate the need to do another iteration of the legalizer after insertingChris Lattner
a libcall. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25730 91177308-0d34-0410-b5e6-96231b3b80d8
