2012-08-11avoid need for -march=mips2 to compile mips atomic.h asmRich Felker-0/+8
linux guarantees ll/sc are always available. on mips1, they will be emulated by the kernel. thus they are part of the linux mips1 abi and safe to use.

sc was overwriting the result
2012-07-11initial version of mips (o32) port, based on work by Richard Pennington (rdp)Rich Felker-0/+191
basically, this version of the code was obtained by starting with rdp's work from his ellcc source tree, adapting it to musl's build system and coding style, auditing the bits headers for discrepencies with kernel definitions or glibc/LSB ABI or large file issues, fixing up incompatibility with the old binutils from aboriginal linux, and adding some new special cases to deal with the oddities of sigaction and pipe syscall interfaces on mips. at present, minimal test programs work, but some interfaces are broken or missing. threaded programs probably will not link.
