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

AlphaISelDAGToDAG.cpp Dwarf requires variable entries to be in the source order. Right now, since we are recording variable information at isel time this means parameters would appear in the reverse order. The short term fix is to issue recordVariable() at asm printing time instead. 2008-02-04 23:06:48 +00:00

README.txt

***

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).
