commit 6220d3865e26ca9a5de3afa960939de22f1bd2f7 parent 083a917d528f85907c5e4a2994f723a91995ca99 Author: Roberto E. Vargas Caballero <k0ga@shike2.com> Date: Wed, 18 Jan 2023 11:48:35 +0100 build: Add initial support for CONF=amd64-freebsd This is only the basic skeleton to build amd64 FreeBSD. Additional work is required to have a working libc. It is only checked that the build finish correctly but we cannot be sure that all the constants defined in this commit are correct. The errno.h file was verified and the _exit() syscall was also checked. Diffstat:
