the code being removed was written to optimize for size assuming the compiler cannot collapse code paths for different types with the same underlying representation. modern compilers sometimes succeed in making this optimization themselves, but either way it's a small size difference and not worth the source-level complexity or the UB involved in this hack. some incorrect use of va_arg still remains, particularly use of void * where the actual argument has a different pointer type. fixing this requires some actual code additions, rather than just removing cruft, so I'm leaving it to be done later as a separate commit.
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
