2007-04-09Next stage into switch lowering refactoringAnton Korobeynikov
1. Fix some bugs in the jump table lowering threshold 2. Implement much better metric for optimal pivot selection 3. Tune thresholds for different lowering methods 4. Implement shift-and trick for lowering small (<machine word length) cases with few destinations. Good testcase will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35816 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-09For PR1146:Reid Spencer
Use ParamAttrsList for writing parameter attributes. Since they are sparse now, we also write them sparsely (saves a few bytes). Unfortunately, this is a bytecode file format change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35811 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-09move a bunch of register constraints from being handled byChris Lattner
getRegClassForInlineAsmConstraint to being handled by getRegForInlineAsmConstraint. This allows us to let the llvm register allocator allocate, which gives us better code. For example, X86/2007-01-29-InlineAsm-ir.ll used to compile to: _run_init_process: subl $4, %esp movl %ebx, (%esp) xorl %ebx, %ebx movl $11, %eax movl %ebx, %ecx movl %ebx, %edx # InlineAsm Start push %ebx ; movl %ebx,%ebx ; int $0x80 ; pop %ebx # InlineAsm End Now we get: _run_init_process: xorl %ecx, %ecx movl $11, %eax movl %ecx, %edx # InlineAsm Start push %ebx ; movl %ecx,%ebx ; int $0x80 ; pop %ebx # InlineAsm End git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35804 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-09Eliminate useless insertelement instructions. This implementsChris Lattner
Transforms/InstCombine/vec_insertelt.ll and fixes PR1286. We now compile the code from that bug into: _foo: movl 4(%esp), %eax movdqa (%eax), %xmm0 movl 8(%esp), %ecx psllw (%ecx), %xmm0 movdqa %xmm0, (%eax) ret instead of: _foo: subl $4, %esp movl %ebp, (%esp) movl %esp, %ebp movl 12(%ebp), %eax movdqa (%eax), %xmm0 #IMPLICIT_DEF %eax pinsrw $2, %eax, %xmm0 xorl %ecx, %ecx pinsrw $3, %ecx, %xmm0 pinsrw $4, %eax, %xmm0 pinsrw $5, %ecx, %xmm0 pinsrw $6, %eax, %xmm0 pinsrw $7, %ecx, %xmm0 movl 8(%ebp), %eax movdqa (%eax), %xmm1 psllw %xmm0, %xmm1 movdqa %xmm1, (%eax) movl %ebp, %esp popl %ebp ret woo :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35788 91177308-0d34-0410-b5e6-96231b3b80d8
