musl - an implementation of the standard library for Linux-based systems
b90841e258
aside from the documented differences, which are the contents of this patch, GCC's -Os also has hard-coded unwanted behaviors which are impossible to override, like refusing to strength-reduce division by a constant to multiplication, presumably because the div saves a couple bytes of code. for this reason, getting rid of -Os and switching to an equivalent default optimization profile based on -O2 has been a long-term goal. as follow-ups, it may make sense to evaluate which of these variations from -O2 actually do anything useful, and eliminate the ones which are not helpful or which throw away performance for insignificant size savings. but for now, I've replicated -Os as closely as possible to provide a baseline for such evaluation. |

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
