From 57fe032c74eb95906cd7e54b0d5fc9463ae46f79 Mon Sep 17 00:00:00 2001 From: Benjamin Reed Date: Tue, 14 May 2024 09:07:10 -0400 Subject: [PATCH] Various arm64 and bootstrap-on-FreeBSD fixes (#427) * comment out conflicting define * add msgSendv for aarch64 from Zoe * Fix arm64 build after llvm 18.1.3 upgrade Apparently clang 18 has become more strict about using floating point registers in inline assembly when -mgeneral-regs-only is used. This causes sys/arm64/arm64/vfp.c to fail to compile, with "error: instruction requires: fp-armv8", and "error: expected readable system register". To fix it, similar to other files compiled for arm64, disable -mgeneral-regs-only for this particular file. PR: 276104 MFC after: 1 month (cherry picked from commit f4d93b67611f6f8b19db7bac6b0973b2ef0cfcb6) * bump to libpng 1.6.43 * disable NEON in libpixman * neon is apparently broken (it's disabled even in upstream ports) * dunno if `-DPIXMAN_TIMERS` is important, but had to turn it off * use MACHINE_ARCH rather than MACHINE in zsh build * skip intel files on arm64 * make sure PATH is set to find bootstrapped python3 * disable some mesa drivers that make linux assumptions * install is called anyway, put the symlinks in there * fix mesa build on arm * don't build docs --------- Co-authored-by:
