previously it was using the same name as the default ABI with hard float (floating point args and return value in registers). the test __SH_FPU_ANY__ || __SH4__ matches what's used in the configure script already, and seems correct under casual review against gcc's config/sh.h, but may need tweaks. the logic for predefined macros for sh, and what they all mean, is very complex. eventually this should be documented in comments here. configure already rejects "half-hard" configurations on sh where double=float since these do not conform to Annex F and are not suitable for musl, so these do not need to be considered here. |

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
the project website:
