2014-07-27fix insufficient synchronization in sh atomic asmRich Felker-1/+2
while other usage I've seen only has the synco instruction after the atomic operation, I cannot find any documentation indicating that this is correct. certainly all stores before the atomic need to have been synchronized before the atomic operation takes place.

2014-03-16superh: fix dynamic linking of __fpscr_valuesBobby Bingham-1/+4
Applications ended up with copy relocations for this array, which resulted in libc's references to this array pointing to the application's copy. The dynamic linker, however, can require this array before the application is relocated, and therefore before the application's copy of this array is initialized. This resulted in garbage being loaded into FPSCR before executing main, which violated the ABI. We fix this by putting the array in crt1 and making the libc copy private. This prevents libc's reference to the array from pointing to an uninitialized copy in the application.
2014-02-27rename superh port to "sh" for consistencyRich Felker-0/+148
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.
