* fcntl.h: O_SEARCH was missing for powerpcrofl0r2012-11-181-12/+9
| | | | | | put some macros that do not differ between architectures in the main header and remove from bits. restructure mips header so it has the same structure as the others.
* fix numerous mips abi constant definition mismatchesRich Felker2012-11-051-5/+5

* add O_EXEC open modeRich Felker2012-09-151-0/+1
| | | | | the linux O_PATH mode provides the necessary semantics for both the O_SEARCH and O_EXEC modes defined and required by POSIX 2008.
* add O_PATH/O_SEARCH support to fcntl.hRich Felker2012-09-131-0/+2
| | | | | | | I'm not 100% sure that Linux's O_PATH meets the POSIX requirements for O_SEARCH, but it seems very close if not perfect. and old kernels ignore it, so O_SEARCH will still work as desired as long as the caller has read permissions to the directory.
* initial version of mips (o32) port, based on work by Richard Pennington (rdp)Rich Felker2012-07-111-0/+36
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.
