https://git.lua4.win/openbsd/atom?h=OPENBSD_7_8_BASE2025-06-09T14:28:34+00:00Make OPENSSL_IA32_SSE2 the default for i386 and remove the flag.2025-06-09T14:28:34+00:00jsing2025-06-09T14:28:34+00:00urn:sha1:951cd4503ff3c4cc93c1a36cf06138b1ddd739d7
The OPENSSL_IA32_SSE2 flag controls whether a number of the perlasm
scripts generate additional implementations that use SSE2 functionality.
In all cases except ghash, the code checks OPENSSL_ia32cap_P for SSE2
support, before trying to run SSE2 code. For ghash it generates a CLMUL
based implementation in addition to different MMX version (one MMX
version hides behind OPENSSL_IA32_SSE2, the other does not), however this
does not appear to actually use SSE2. We also disable AES-NI on i386 if
OPENSSL_IA32_SSE2.
On OpenBSD, we've always defined OPENSSL_IA32_SSE2 so this is effectively
a no-op. The only change is that we now check MMX rather than SSE2 for the
ghash MMX implementation.

Remove GNU assembler version check.2025-06-09T13:58:28+00:00jsing2025-06-09T13:58:28+00:00urn:sha1:d8ae322f91ae730f31b750787e0180588dab36dc
GNU assembler version 2.19 was released in 2014, so it does not seem
unreasonable to expect that we have an assembler that supports AVX.
Furthermore, the current check fails on LLVM.

Now that we have replacement SHA-256 and SHA-512 assembly implementations
for amd64, sha512-x86_64.pl can go the way of the dodo.
Replace uses of endbr64 with _CET_ENDBR from cet.h2024-02-24T15:30:14+00:00tb2024-02-24T15:30:14+00:00urn:sha1:c730c3b3b1845cc7c4a4aceff2031f1135faa6bb
cet.h is needed for other platforms to emit the relevant .gnu.properties
sections that are necessary for them to enable IBT. It also avoids issues
with older toolchains on macOS that explode on encountering endbr64.

Use .section .rodata instead of a plain .rodata2023-02-09T19:57:00+00:00tb2023-02-09T19:57:00+00:00urn:sha1:4355eb6aeababf0126972f85bdeed63048a99df1
At least gcc 12 on Fedora is very unhappy about a plain .rodata and throws
Error: unknown pseudo-op: `.rodata'. So add a .section in front of it to
make it happy.
