[libc] Add support to compile some syscalls on 32 bit platform 2023-08-03T13:08:01+00:00 Mikhail R. Gadelha mikhail@igalia.com 2023-08-03T12:30:36+00:00 c9783d2bda95ec6921b3ca2df930b17af3a6c7b1 This patch adds a bunch of ifdefs to handle the 32 bit versions of some syscalls, which often only append a 64 to the name of the syscall (with exception of SYS_lseek -> SYS_llseek and SYS_futex -> SYS_futex_time64) This patch also tries to handle cases where wait4 is not available (as in riscv32): to implement wait, wait4 and waitpid when wait4 is not available, we check for alternative wait calls and ultimately rely on waitid to implement them all. In riscv32, only waitid is available, so we need it to support this platform. Reviewed By: michaelrj Differential Revision: https://reviews.llvm.org/D148371
