Description
Add assembly for Poly1305 using ARM32 NEON instruction set.
For Poly1305 ARM32 Base:
Change name from poly1305_blocks_arm32_16 to poly1305_arm32_blocks_16
Update location of fields in Poly1305 objects
poly1305.c:
ARM32 NEON - buffer up to 4 blocks
x86_64 - only calculate powers of r once after key is set.
test.c: poly1305 testing with multiple updates.
benchmark: chacha20-poly1305 now uses AAD
Testing
Tested Poly1305 for all ARM32 CPU types supported.
