History log of /src/sys/crypto/aes/arch/x86/aes_ni_64.S
Revision	Date	Author	Comments
1.6	27-Jul-2020	riastradh	Add RCSIDs to the AES and ChaCha .S sources.
1.5	27-Jul-2020	riastradh	Align critical-path loops in AES and ChaCha.
1.4	25-Jul-2020	riastradh	Implement AES-CCM with x86 AES-NI.
1.3	25-Jul-2020	riastradh	Invert some loops to save a jmp instruction on each iteration. No semantic change intended.
1.2	30-Jun-2020	riastradh	Use .p2align rather than .align. Apparently on arm, .align is actually an alias for .p2align, taking a power of two rather than a number of bytes, so aes_armv8_64.o was bloated to 32KB with obscene alignment when it only needed to be barely past 4KB. Do the same for the x86 aes_ni_64.S -- even though .align takes a number of bytes rather than a power of two on x86, let's just stay away from the temptations of the evil .align directive.
1.1	29-Jun-2020	riastradh	Add x86 AES-NI support. Limited to amd64 for now. In principle, AES-NI should work in 32-bit mode, and there may even be some 32-bit-only CPUs that support AES-NI, but that requires work to adapt the assembly.
