2005-11-19Teach LLVM how to scalarize packed types. Currently, this only works onNate Begeman
packed types with an element count of 1, although more generic support is coming. This allows LLVM to turn the following code: void %foo(<1 x float> * %a) { entry: %tmp1 = load <1 x float> * %a; %tmp2 = add <1 x float> %tmp1, %tmp1 store <1 x float> %tmp2, <1 x float> *%a ret void } Into: _foo: lfs f0, 0(r3) fadds f0, f0, f0 stfs f0, 0(r3) blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24416 91177308-0d34-0410-b5e6-96231b3b80d8

assemblerdoesn't support .asciz, just set AscizDirective to null in your asmprinter.

2005-11-08Change the ValueList array for each node to be shared instead of ↵Chris Lattner
individuallyallocated. Further, in the common case where a node has a single value, justreference an element from a small array. This is a small compile-time win. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24251 91177308-0d34-0410-b5e6-96231b3b80d8
2005-11-08Switch the operandlist/valuelist from being vectors to being just an ↵Chris Lattner
array.This saves 12 bytes from SDNode, but doesn't speed things up substantially (our graphs apparently already fit within the cache on my g5). In any case this reduces memory usage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24249 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-30Significantly simplify this code and make it more aggressive. Instead of havingChris Lattner
a special case hack for X86, make the hack more general: if an incoming argument register is not used in any block other than the entry block, don't copy it to a vreg. This helps us compile code like this: %struct.foo = type { int, int, [0 x ubyte] } int %test(%struct.foo* %X) { %tmp1 = getelementptr %struct.foo* %X, int 0, uint 2, int 100 %tmp = load ubyte* %tmp1 ; <ubyte> [#uses=1] %tmp2 = cast ubyte %tmp to int ; <int> [#uses=1] ret int %tmp2 } to: _test: lbz r3, 108(r3) blr instead of: _test: lbz r2, 108(r3) or r3, r2, r2 blr The (dead) copy emitted to copy r3 into a vreg for extra-block uses was increasing the live range of r3 past the load, preventing the coallescing. This implements CodeGen/PowerPC/reg-coallesce-simple.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24115 91177308-0d34-0410-b5e6-96231b3b80d8
2005-10-30Reduce the number of copies emitted as machine instructions byChris Lattner
generating results in vregs that will need them. In the case of something like this: CopyToReg((add X, Y), reg1024), we no longer emit code like this: reg1025 = add X, Y reg1024 = reg 1025 Instead, we emit: reg1024 = add X, Y Whoa! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24111 91177308-0d34-0410-b5e6-96231b3b80d8
