modules/crypto: reenable assembly optimized skein implementation

2020-10-10T01:13:14Z

r366344 corrected the optimized amd64 skein assembly implementation, so we can now enable it again. Also add a dependency on this Makefile for the skein_block object, so that it will be rebuit (similar to r366362). PR: 248221 Sponsored by: The FreeBSD Foundation

modules/crypto: disable optimized assembly skein1024 implementation

It is presumably broken in the same way as userland skein1024 (see r363454) PR: 248221

Rename skein_block_asm.s to .S and assemble using Clang IAS

2020-06-06T00:35:41Z

Comparing the object files produced by GNU as 2.17.50 and Clang IAS shows many immaterial changes in strtab etc., and one material change in .text: 1bac: 4c 8b 4f 18 mov 0x18(%rdi),%r9 1bb0: eb 0e jmp 1bc0 - 1bb2: 66 66 2e 0f 1f 84 00 data16 nopw %cs:0x0(%rax,%rax,1) - 1bb9: 00 00 00 00 - 1bbd: 0f 1f 00 nopl (%rax) + 1bb2: 66 2e 0f 1f 84 00 00 nopw %cs:0x0(%rax,%rax,1) + 1bb9: 00 00 00 + 1bbc: 0f 1f 40 00 nopl 0x0(%rax) 0000000000001bc0 : Skein1024_block_loop(): 1bc0: 4c 8b 47 10 mov 0x10(%rdi),%r8 1bc4: 4c 03 85 c0 00 00 00 add 0xc0(%rbp),%r8 That is, GNU as and Clang's integrated assembler use different multi- byte NOPs for alignment (GNU as emits an 11 byte NOP + a 3 byte NOP, while Clang IAS emits a 10 byte NOP + a 4 byte NOP). Dependency cleanup hacks are not required, because we do not create .depend files from GNU as.

Also pass SKEIN_USE_ASM to the assembler, via AFLAGS

Apply C SKEIN_LOOP setting only to skein_block.c

2020-06-05T17:00:38Z

Otherwise if assembling skein_block_asm.s with Clang's integrated assembler we can pass conflicting SKEIN_LOOP settings (via CFLAGS and ACFLAGS).

Add opt_compat.h needed by r359374.
