2013-03-29[mips] Define overloaded versions of storeRegToStack and loadRegFromStack.Akira Hatanaka
No functionality changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178327 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-25Make pseudos FEXT_CCRX16_ins and FEXT_CCRXI16_ins into custom emitters.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176007 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-24 Make psuedo FEXT_T8I816_ins into a custom emitter.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176002 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-24Make psuedo FEXT_T8I816_ins a custom inserter. It should be expandedReed Kotler
as early as possible; which means during instruction selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175984 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-20Expand pseudos/macros:Reed Kotler
SltCCRxRy16, SltiCCRxImmX16, SltiuCCRxImmX16, SltuCCRxRy16 $T8 shows up as register $24 when emitted from C++ code so we had to change some tests that were already there for this functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175593 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-19Expand pseudos/macros BteqzT8SltiX16, BteqzT8SltiuX16,Reed Kotler
BtnezT8SltiX16, BtnezT8SltiuX16 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175486 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-19Expand pseudos BteqzT8CmpiX16 and BtnezT8CmpiX16.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175474 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Expand macro/pseudo instructions BtnezT8SltX16 and BtnezT8SltuX16.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175420 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Expand pseudo/macro BteqzT8SltuX16 . There is no test case becauseReed Kotler
at this time, llvm is generating a different but equivalent pattern that would lead to this instruction. I am trying to think of a way to get it to generate this. If I can't, I may just remove the pseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175419 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Expand pseudo/macro BteqzT8SltX16.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175417 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Expand macro/pseudo BteqzT8CmpX16.Reed Kotler
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175416 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Beginning of expanding all current mips16 macro/pseudo instruction sequences.Reed Kotler
This expansion will be moved to expandISelPseudos as soon as I can figure out how to do that. There are other instructions which use this ExpandFEXT_T8I816_ins and as soon as I have finished expanding them all, I will delete the macro asm string text so it has no way to be used in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175413 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-16One more try to make this look nice. I have lots of pseudo lowering Reed Kotler
as well as 16/32 bit variants to do and so I want this to look nice when I do it. I've been experimenting with this. No new test cases are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175369 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-16Use a different scheme to chose 16/32 variants. This scheme is moreReed Kotler
consistent with how BuildMI works. No new tests needed. All should work the same as before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175342 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-13For Mips 16, add the optimization where the 16 bit form of addiu sp can be usedReed Kotler
if the offset fits in 11 bits. This makes use of the fact that the abi requires sp to be 8 byte aligned so the actual offset can fit in 8 bits. It will be shifted left and sign extended before being actually used. The assembler or direct object emitter will shift right the 11 bit signed field by 3 bits. We don't need to deal with that here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175073 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08When Mips16 frames grow large, the immediate field may exceed the maximumReed Kotler
allowed size for the instruction. This code uses RegScavenger to fix this. We sometimes need 2 registers for Mips16 so we must handle things differently than how register scavenger is normally used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174696 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-19This is a resubmittal. For some reason it broke the bots yesterdayJack Carter
but I cannot reproduce the problem and have scrubed my sources and even tested with llvm-lit -v --vg. Formatting fixes. Mostly long lines and blank spaces at end of lines. Contributer: Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172882 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20fix most of remaining issues with large frames.Reed Kotler
these patches are tested a lot by test-suite but make check tests are forthcoming once the next few patches that complete this are committed. with the next few patches the pass rate for mips16 is near 100% git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170656 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
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
2012-10-31Implement ADJCALLSTACKUP and ADJCALLSTACKDOWNReed Kotler

2012-10-30Change mips16 delay slot jumps to non delay slot forms by default.Reed Kotler
We will make them delay slot forms if there is something that can be placed in the delay slot during a separate pass. Mips16 extended instructions cannot be placed in delay slots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166990 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-281. Add load/store words from the stackReed Kotler
2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and moved other lines for FEXT_RI16 formats to be in the right place in the code. 3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment. 4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164811 91177308-0d34-0410-b5e6-96231b3b80d8
