Raw Normal View History

Add test for ioctl(SIOCGIFCONF) and polyfill on BSDs - Use nullness checks when calling weakly linked functions. - Avoid typedef for reasons described in Linux Kernel style guide. - Avoid enum in in Windows headers. Earlier in Cosmo's history all one hundred files in libc/nt/enum/ used to be enums and it resulted in gigabytes of DWARF data almost as large as everything else in the codebase combined. - Bitfields aren't our friends. They have frequent ABI breakages, inconsistent arithmetic across compilers, and different endianness between cpus. Compiler authors also haven't invested much roi into making bit fields go fast so they produce poor assembly. - Use memccpy() instead of strncpy() or snprintf() for length-bounded copying of C strings. strncpy() is a misunderstood function and snprintf() is awesome but memccpy() deserves more love.

Make improvements - Let OpenMP be usable via cosmocc - Let libunwind be usable via cosmocc - Make X86_HAVE(AVXVNNI) work correctly - Avoid using MAP_GROWSDOWN on qemu-aarch64 - Introduce in6addr_any and in6addr_loopback - Have thread stacks use MAP_GROWSDOWN by default - Ask OpenMP to not use filesystem to manage threads - Make NI_MAXHOST and NI_MAXSERV available w/o _GNU_SOURCE
