* [mips] Lower EH_RETURN.Akira Hatanaka2013-01-301-0/+29
| | | | | | | Patch by Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173862 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Use "or $r0, $r1, $zero" instead of "addu $r0, $zero, $r1" to copyAkira Hatanaka2012-12-201-5/+5
| | | | | | | | | | | | physical register $r1 to $r0. GNU disassembler recognizes an "or" instruction as a "move", and this change makes the disassembled code easier to read. Original patch by Reed Kotler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170655 91177308-0d34-0410-b5e6-96231b3b80d8
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-3/+3
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Stop reserving register AT and use register scavenger when a scratchAkira Hatanaka2012-11-031-7/+10
| | | | | | | | register is needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167341 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Delete MipsFunctionInfo::EmitNOAT. Unconditionally print directiveAkira Hatanaka2012-11-021-1/+0
| | | | | | | | | "set .noat" so that the assembler doesn't issue warnings when register $AT is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167310 91177308-0d34-0410-b5e6-96231b3b80d8
* Make function loadImmediate a member of MipsSEInstrInfo and change it to returnAkira Hatanaka2012-08-231-4/+43
| | | | | | | | | | | | 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. No changes in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162417 91177308-0d34-0410-b5e6-96231b3b80d8
