..
AsmPrinter Remove unused AsmPrinter OptLevel argument, and propogate. 2009-07-01 01:48:54 +00:00
Alpha.h Remove unused AsmPrinter OptLevel argument, and propogate. 2009-07-01 01:48:54 +00:00
Alpha.td Move target independent td files from lib/Target/ to include/llvm/Target so they can be distributed along with the header files. 2008-11-24 07:34:46 +00:00
AlphaBranchSelector.cpp Tidy up several unbeseeming casts from pointer to intptr_t. 2008-09-04 17:05:41 +00:00
AlphaCodeEmitter.cpp Fix new CodeEmitter stuff to follow LLVM codying style. Patch by Aaron Gray 2009-06-01 19:57:37 +00:00
AlphaISelDAGToDAG.cpp Convert Alpha and Mips to use a MachineFunctionInfo subclass to 2009-06-03 20:30:14 +00:00
AlphaISelLowering.cpp Update comments to make it clear that the function alignment is the Log2 of the 2009-07-01 18:50:55 +00:00
AlphaISelLowering.h Update comments to make it clear that the function alignment is the Log2 of the 2009-07-01 18:50:55 +00:00
AlphaInstrFormats.td Rename isSimpleLoad to canFoldAsLoad, to better reflect its meaning. 2008-12-03 18:15:48 +00:00
AlphaInstrInfo.cpp Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details. 2009-07-01 01:59:31 +00:00
AlphaInstrInfo.h Convert Alpha and Mips to use a MachineFunctionInfo subclass to 2009-06-03 20:30:14 +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).
