2005-07-12Implement Subtarget supportNate Begeman
Implement the X86 Subtarget. This consolidates the checks for target triple, and setting options based on target triple into one place. This allows us to convert the asm printer and isel over from being littered with "forDarwin", "forCygwin", etc. into just having the appropriate flags for each subtarget feature controlling the code for that feature. This patch also implements indirect external and weak references in the X86 pattern isel, for darwin. Next up is to convert over the asm printers to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22389 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-10Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.Chris Lattner
This is the last MVTSDNode. This allows us to eliminate a bunch of special case code for handling MVTSDNodes. Also, remove some uses of dyn_cast that should really be cast (which is cheaper in a release build). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22368 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22341 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-06First round of support for doing scalar FP using the SSE2 ISA extension andNate Begeman
XMM registers. There are many known deficiencies and fixmes, which will be addressed ASAP. The major benefit of this work is that it will allow the LLVM register allocator to allocate FP registers across basic blocks. The x86 backend will still default to x87 style FP. To enable this work, you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc. An example before and after would be for: double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i) Sum += P[i]; return Sum; } The inner loop looks like the following: x87: .LBB_foo_1: # no_exit fldl (%esp) faddl (%eax,%ecx,8) fstpl (%esp) incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit SSE2: addsd (%eax,%ecx,8), %xmm0 incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22340 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-05Make several cleanups to Andrews varargs change:Chris Lattner
1. Pass Value*'s into lowering methods so that the proper pointers can be added to load/stores from the valist 2. Intrinsics that return void should only return a token chain, not a token chain/retval pair. 3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone. 4. Now that we have Value*'s available in the lowering methods, pass them into any load/stores from the valist that are emitted git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22339 91177308-0d34-0410-b5e6-96231b3b80d8

2005-06-27So, it turns out I forgot that one valid way of restoring GP after a callAndrew Lenharth

2005-06-27Initial set of .td file changes necessary to get scalar fp in xmm registersNate Begeman
working. The instruction selector changes will hopefully be coming later this week once they are debugged. This is necessary to support the darwin x86 FP model, and is recommended by intel as the replacement for x87. As a bonus, the register allocator knows how to deal with these registers across basic blocks, unliky the FP stackifier. This leads to significantly better codegen in several cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22300 91177308-0d34-0410-b5e6-96231b3b80d8
