Jakob Stoklund Olesen 9bbe4d6c00 Clean up the handling of the x87 fp stack to make it more robust. ... Drop the FpMov instructions, use plain COPY instead. Drop the FpSET/GET instruction for accessing fixed stack positions. Instead use normal COPY to/from ST registers around inline assembly, and provide a single new FpPOP_RETVAL instruction that can access the return value(s) from a call. This is still necessary since you cannot tell from the CALL instruction alone if it returns anything on the FP stack. Teach fast isel to use this. This provides a much more robust way of handling fixed stack registers - we can tolerate arbitrary FP stack instructions inserted around calls and inline assembly. Live range splitting could sometimes break x87 code by inserting spill code in unfortunate places. As a bonus we handle floating point inline assembly correctly now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134018 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-28 18:32:28 +00:00
