* First round of support for doing scalar FP using the SSE2 ISA extension andNate Begeman2005-07-061-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 llvm-svn: 22340

This instruction implicitly defines all x86 fp registers and is a terminator so that passes which add machine code at the end of basic blocks (like phi elimination) do not add instructions between it and the branch or return instruction. llvm-svn: 10562
* Finally, _actually delete the machine code_ for a function, after it hasChris Lattner2003-12-201-0/+3
