From fa872e1b6210e81e60d6029429f0a083b8eab26e Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 2 Dec 2016 16:32:28 -0200 Subject: Clean pthread functions namespaces for C11 threads This patch adds internal definition (through {libc_}hidden_{proto,def}) and also change some strong to weak alias for symbols that might be used by C11 threads implementations. The patchset should not change libc/libpthread functional, although object changes are expected (since now internal symbols are used instead) and final exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread usage of __mmap{64}, __munmap, __mprotect). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). * include/sched.h (__sched_get_priority_max): Add libc hidden proto.
