AlphaAsmPrinter.cpp Add a quick and dirty "loop aligner pass". x86 uses it to align its loops to 16-byte boundaries. 2008-02-28 00:43:03 +00:00
AlphaBranchSelector.cpp rename MachineInstr::setInstrDescriptor -> setDesc 2008-01-11 18:10:50 +00:00
AlphaCodeEmitter.cpp Change MachineRelocation::DoesntNeedFnStub to NeedStub. This fields will be used 2008-01-03 02:56:28 +00:00

AlphaInstrInfo.cpp It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned. 2008-02-08 21:20:40 +00:00
AlphaInstrInfo.h Rename MRegisterInfo to TargetRegisterInfo. 2008-02-10 18:45:23 +00:00
AlphaInstrInfo.td Final de-tabification. 2008-02-27 06:33:05 +00:00
AlphaISelDAGToDAG.cpp Convert MaskedValueIsZero and all its users to use APInt. Also add 2008-02-25 21:11:39 +00:00
AlphaISelLowering.cpp Implement x86 support for @llvm.prefetch. It corresponds to prefetcht{0|1|2} and prefetchnta instructions. 2008-03-08 00:58:38 +00:00
AlphaISelLowering.h Atomic op support. If any gcc test uses __sync builtins, it might start failing on archs that haven't implemented them yet 2008-02-21 06:45:13 +00:00

***

add gcc builtins for alpha instructions


***

custom expand byteswap into nifty 
extract/insert/mask byte/word/longword/quadword low/high
sequences

***

see if any of the extract/insert/mask operations can be added

***

match more interesting things for cmovlbc cmovlbs (move if low bit clear/set)

***

lower srem and urem

remq(i,j):  i - (j * divq(i,j)) if j != 0
remqu(i,j): i - (j * divqu(i,j)) if j != 0
reml(i,j):  i - (j * divl(i,j)) if j != 0
remlu(i,j): i - (j * divlu(i,j)) if j != 0

***

add crazy vector instructions (MVI):

(MIN|MAX)(U|S)(B8|W4) min and max, signed and unsigned, byte and word
PKWB, UNPKBW pack/unpack word to byte
PKLB UNPKBL pack/unpack long to byte
PERR pixel error (sum accross bytes of bytewise abs(i8v8 a - i8v8 b))

cmpbytes bytewise cmpeq of i8v8 a and i8v8 b (not part of MVI extentions)

this has some good examples for other operations that can be synthesised well 
from these rather meager vector ops (such as saturating add).
