this commit mostly makes consistent things like spacing, function ordering in atomic_arch.h, argument names, use of volatile, etc. the fake 64-bit and/or atomics are also removed because the shared atomic.h does a better job of implementing them; it avoids making two atomic memory accesses when only one 32-bit half needs to be touched. no major overhaul is needed or possible because x86 actually has native versions of all the usual atomic operations, rather than using ll/sc or needing cas loops.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
