* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | 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

* This patch adds the register class for MIPS16 as well as the ability forAkira Hatanaka2012-05-16
| | | | | | | | | | | | | | | | llc to recognize MIPS16 as a MIPS ASE extension. -mips16 will mean the mips16 ASE for mips32 by default. As part of fixing of adding this we discovered some small changes that need to be made to MipsInstrInfo::storeRegToStackSLot and MipsInstrInfo::loadRegFromStackSlot. We were using some "==" equality tests where in fact we should have been using Mips::<regclas>.hasSubClassEQ instead, per suggestion of Jakob Stoklund Olesen.

* Fix handling of double precision loads and stores when Mips1 is targeted. Akira Hatanaka2011-08-16
| | | | | | | | | | | | | | | | | Mips1 does not support double precision loads or stores, therefore two single precision loads or stores must be used in place of these instructions. This patch treats double precision loads and stores as if they are legal instructions until MCInstLowering, instead of generating the single precision instructions during instruction selection or Prolog/Epilog code insertion. Without the changes made in this patch, llc produces code that has the same problem described in r137484 or bails out when MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137711 91177308-0d34-0410-b5e6-96231b3b80d8
