2020-04-18fix sh fesetround failure to clear old modeRich Felker-0/+2
the sh version of fesetround or'd the new rounding mode onto the control register without clearing the old rounding mode bits, making changes sticky. this was the root cause of multiple test failures.

these are not public interfaces and do not match the public function, but delegate argument checking to it.

2014-02-27rename superh port to "sh" for consistencyRich Felker-0/+74
linux, gcc, etc. all use "sh" as the name for the superh arch. there was already some inconsistency internally in musl: the dynamic linker was searching for "ld-musl-sh.path" as its path file despite its own name being "ld-musl-superh.so.1". there was some sentiment in both directions as to how to resolve the inconsistency, but overall "sh" was favored.
