Hi,
v2 of glibc port to ARC processors from Synopsys.
Thx for reviewing the v1 [1], I've hopefully addressed all the comments.
Any unlikely omissions are unintended.
Also apologies for the bad timing given the imminent release, but that ship
has likely already sailed, so we might as well continue our march independently.
The main changes since v1 are
* sigaction updates
- drop sigaction.h, use generic version
- sigaction.c to use generic linux/sigaction.c
- arch specific __sigset_t.h to enable __sigset_t [2] vs. [128]
* atomics: Enable USE_ATOMIC_COMPILER_BUILTINS
* switch to init_array, removed crt{i,n}
* Build: remove libc_cv_fpie=no
* __startcontext: use cfi_undefined to terminate unwinder
* dropped ldconfig.h, libnsl.abilist, cacheflush.c (use syscalls.list),
procfs-id.h, math_private.h
* cosmetics
- Trying to follow the coding style and conventions
- Folded the testsuite fixes patches into main port patches
- Update copyright headers to 2019
