2006-10-12Lower X%C into X/C+stuff. This allows the 'division by a constant' logic toChris Lattner
apply to rems as well as divs. This fixes PR945 and speeds up ReedSolomon from 14.57s to 10.90s (which is now faster than gcc). It compiles CodeGen/X86/rem.ll into: _test1: subl $4, %esp movl %esi, (%esp) movl $2155905153, %ecx movl 8(%esp), %esi movl %esi, %eax imull %ecx addl %esi, %edx movl %edx, %eax shrl $31, %eax sarl $7, %edx addl %eax, %edx imull $255, %edx, %eax subl %eax, %esi movl %esi, %eax movl (%esp), %esi addl $4, %esp ret _test2: movl 4(%esp), %eax movl %eax, %ecx sarl $31, %ecx shrl $24, %ecx addl %eax, %ecx andl $4294967040, %ecx subl %ecx, %eax ret _test3: subl $4, %esp movl %esi, (%esp) movl $2155905153, %ecx movl 8(%esp), %esi movl %esi, %eax mull %ecx shrl $7, %edx imull $255, %edx, %eax subl %eax, %esi movl %esi, %eax movl (%esp), %esi addl $4, %esp ret instead of div/idiv instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30920 91177308-0d34-0410-b5e6-96231b3b80d8

2006-10-12Fix massive resource leaks in the bytecode reader. Reading a bytecode fileChris Lattner
with ParseBytecodeFile used to leak both a ModuleProvider (and related bytecode parser stuff attached to it) AND a file descriptor, which was never closed. This prevented gccld/llvm-ld/llvm-link from linking together apps with more that ~252 .bc files on darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30912 91177308-0d34-0410-b5e6-96231b3b80d8

the stack slot. This fixes PR943. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30898 91177308-0d34-0410-b5e6-96231b3b80d8
2006-10-12Prior load folding check on chain operand was too strict. It requires theEvan Cheng
chain operand to point to the load being folded. Now we relax this, traversing up the chain, if it doesn't reach the load, then it's ok. We will create a TokenFactor (of all the chain operands and the load's chain) to capture all the control flow dependencies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30897 91177308-0d34-0410-b5e6-96231b3b80d8

2006-10-11Use cute tblgen tricks to make zap handling more powerful. Specifically,Chris Lattner
when the dag combiner simplifies an and mask, notice this and allow those bits to be missing from the zap mask. This compiles Alpha/zapnot4.ll into: sll $16,3,$0 zapnot $0,3,$0 ret $31,($26),1 instead of: ldah $0,1($31) lda $0,-8($0) sll $16,3,$1 and $1,$0,$0 ret $31,($26),1 It would be *really* nice to replace the hunk of code in the AlphaISelDAGToDAG.cpp file that matches (and (srl (x, C), c2) into (SRL (ZAPNOTi)) with a similar pattern, but I've spent enough time poking at alpha. Make andrew will do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30875 91177308-0d34-0410-b5e6-96231b3b80d8
