prior to commit 2f853dd6b9a95d5b13ee8f9df762125e0588df5d which overhauled the makefile for out-of-tree builds, crt/*.c files were replaceable by crt/$(ARCH)/*.s, and top-level ldso/ did not exist (its files were under src/ldso). since then, crti.o and crtn.o have been hard-coded as arch-specific, but none of the other files in crt/ or ldso/ were replaceable at all. in preparation for easy integration with midipix, which has a port of musl to windows, it needs to be possible to override the ELF-specific code in these files. making the same arch-replacements system work throughout the whole source tree also improves consistency and removes the need for some file-specific rules (crti.o and crtn.o) in the makefile.
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
