From a1bdd81664aa681364da368154c48501db249df9 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 21 Apr 2022 09:41:59 -0300 Subject: Refactor internal-signals.h The main drive is to optimize the internal usage and required size when sigset_t is embedded in other data structures. On Linux, the current supported signal set requires up to 8 bytes (16 on mips), was lower than the user defined sigset_t (128 bytes). A new internal type internal_sigset_t is added, along with the functions to operate on it similar to the ones for sigset_t. The internal-signals.h is also refactored to remove unused functions Besides small stack usage on some functions (posix_spawn, abort) it lower the struct pthread by about 120 bytes (112 on mips). Checked on x86_64-linux-gnu.
