..
AsmPrinter eliminate the now-unneeded context argument of MBB::getSymbol() 2010-03-13 21:04:28 +00:00
TargetInfo make -fno-rtti the default unless a directory builds with REQUIRES_RTTI. 2010-01-24 20:43:08 +00:00
Alpha.h eliminate all the dead addSimpleCodeEmitter implementations. 2010-02-02 21:31:47 +00:00
Alpha.td Switch Alpha over to the new call lowering style. New code mostly 2009-07-19 01:11:32 +00:00
AlphaBranchSelector.cpp Remove includes of Support/Compiler.h that are no longer needed after the 2009-10-25 06:57:41 +00:00
AlphaCallingConv.td Fix PR6444, note still doesn't compile libgcc2 all the way, but fixes that error. May not fix it in an ABI complient way. It wasn't clear what gcc does 2010-03-03 20:15:31 +00:00
AlphaCodeEmitter.cpp move target-independent opcodes out of TargetInstrInfo 2010-02-09 19:54:29 +00:00
AlphaInstrFormats.td Rename isSimpleLoad to canFoldAsLoad, to better reflect its meaning. 2008-12-03 18:15:48 +00:00

AlphaISelDAGToDAG.cpp Sink InstructionSelect() out of each target into SDISel, and rename it 2010-03-02 06:34:30 +00:00
AlphaISelLowering.cpp Move TLOF implementations to libCodegen to resolve layering violation. 2010-02-15 22:37:53 +00:00
AlphaISelLowering.h Revert 95130. 2010-02-02 23:55:14 +00:00
AlphaJITInfo.cpp Change indirect-globals to use a dedicated allocIndirectGV. This lets us 2009-12-15 22:42:46 +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).
