* [mips] Fix instruction selection pattern for sint_to_fp node to avoid ↵Akira Hatanaka2013-05-161-0/+3
| | | | | | | | | | | | | | | | | | | | emitting an invalid instruction sequence. Rather than emitting an int-to-FP move instruction and an int-to-FP conversion instruction during instruction selection, we emit a pseudo instruction which gets expanded post-RA. Without this change, register allocation can possibly insert a floating point register move instruction between the two instructions, which is not valid according to the ISA manual. mtc1 $f4, $4 # int-to-fp move instruction. mov.s $f2, $f4 # move contents of $f4 to $f2. cvt.s.w $f0, $f2 # int-to-fp conversion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182042 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Add option -mno-ldc1-sdc1.Akira Hatanaka2013-05-131-0/+3
| | | | | | | | | This option is used when the user wants to avoid emitting double precision FP loads and stores. Double precision FP loads and stores are expanded to single precision instructions after register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181718 91177308-0d34-0410-b5e6-96231b3b80d8

* Make function loadImmediate a member of MipsSEInstrInfo and change it to returnAkira Hatanaka2012-08-231-1/+7
| | | | | | | | | | | | the temporary register that was used to load the immediate. Currently, it always returns register $at, but this will change if, in the future, we decide to use another register.
