the dynamic linker was found to hang when used as the PT_INTERP, but
not when invoked as a command. the mechanism of this failure was not
determined, but the cause is clear:
commit 5552ce5200 removed the SHARED
macro, but arch/sh/crt_arch.h is still using it to choose the right
form of the crt/ldso entry point code. moving the forced definition
from rcrt1.c to dlstart.c restores the old behavior. eventually the
logic should be changed to fully remove the SHARED macro or at least
rename it to something more reasonable.
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
