History

Oscar Fuentes 92adc19be9 Adds extern "C" ints to the .cpp files that use RegisterTarget, as well as 2 files that use "Registrator"s. These are to be used by the MSVC builds, as the Win32 linker does not include libs that are otherwise unreferenced, even if global constructors in the lib have side-effects. Patch by Scott Graham! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59378 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-15 21:36:30 +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).
