# SHA256/512 block procedure for PA-RISC.
|
||
|
|
|
||
|
|
# June 2009.
|
||
|
|
#
|
||
|
|
# SHA256 performance is >75% better than gcc 3.2 generated code on
|
||
|
|
# PA-7100LC. Compared to code generated by vendor compiler this
|
||
|
|
# implementation is almost 70% faster in 64-bit build, but delivers
|
||
|
|
# virtually same performance in 32-bit build on PA-8600.
|
||
|
|
#
|
||
|
|
# SHA512 performance is >2.9x better than gcc 3.2 generated code on
|
||
|
|
# PA-7100LC, PA-RISC 1.1 processor. Then implementation detects if the
|
||
|
|
# code is executed on PA-RISC 2.0 processor and switches to 64-bit
|
||
|
|
# code path delivering adequate performance even in "blended" 32-bit
|
||
|
|
# build. Though 64-bit code is not any faster than code generated by
|
||
|
|
# vendor compiler on PA-8600...
