* Make OPENSSL_IA32_SSE2 the default for i386 and remove the flag.jsing2025-06-092-6/+2
| | | | | | | | | | | | | | | | | 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. ok bcook@ beck@
* Remove GNU assembler version check.jsing2025-06-091-4/+1
| | | | | | | | 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. ok bcook@ beck@

* Remove sha512-x86_64.pl.jsing2024-11-161-347/+0
| | | | | 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.htb2024-02-242-5/+5
| | | | | | | | | 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. based on a diff by kettenis ok beck kettenis

| | | | | | | | 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. ok deraadt miod

* For xonly, move sha512-ppc.pl's table from text to rodatagkoehler2023-02-011-18/+7
| | | | | | | | | | | OpenBSD/macppc will enforce xonly on PowerPC G5, then libcrypto's sha256 would crash by SIGSEGV, because it can't read text. Use ELF relocations "@ha" and "@l" to find the table in rodata. This might break the PowerPC asm on a not-ELF platform (like AIX or Mac OS) if someone would try it there. ok kettenis@ deraadt@

| | | | | | | | | | | | | | | meaningful constants in a private header file, so that reviewers can actually get a chance to figure out what the code is attempting to do without knowing all cpuid bits. While there, turn it from an array of two 32-bit ints into a properly aligned 64-bit int. Use of OPENSSL_ia32_P is now restricted to the assembler parts. C code will now always use OPENSSL_cpu_caps() and check for the proper bits in the whole 64-bit word it returns. i386 tests and ok jsing@

However, when running under a 32-bit OpenBSD/hppa kernel, there is no guarantee that the upper part of the registers will be preserved accross context switches (or even userland->kernel boundaries), which causes this code to fail. Wrap the generated code within #ifndef __OpenBSD__ in that case, to avoid using the 64-bit code completely. (OpenBSD/hppa64, once stable, will not be affected by this)
