*	add clang-compatible thread-pointer code for mips	Rich Felker	2012-09-07	1	-0/+4
\| \| \| \| \| \| \| \| \| \|	clang does not presently support the "v" constraint we want to use to get the result from $3, and trying to use register...__asm__("$3") to do the same invokes serious compiler bugs. so for now, i'm working around the issue with an extra temp register and putting $3 in the clobber list instead of using it as output. when the bugs in clang are fixed, this issue should be revisited to generate smaller/faster code like what gcc gets.
*	avoid "inline" in public headers for strict c89 compatibility	Rich Felker	2012-09-02	1	-7/+7
\| \| \| \| \| \| \| \| \|	while musl itself requires a c99 compiler, some applications insist on being compiled with c89 compilers, and use of "inline" in the headers was breaking them. much of this had been avoided already by just skipping the inline keyword in pre-c99 compilers or modes, but this new unified solution is cleaner and may/should result in better code generation in the default gcc configuration.
*	avoid need for -march=mips2 to compile mips atomic.h asm	Rich Felker	2012-08-11	1	-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.
*	fix incorrect ptrdiff_t type on mips	Rich Felker	2012-08-10	1	-1/+1

*	add defines for number of sigset_t bytes syscalls expect	Rich Felker	2012-08-09	1	-0/+2
\| \| \| \|	yet another gratuitous mips incompatibility...
*	further fixes for mips ioctl.h header	Rich Felker	2012-08-07	1	-4/+4
\| \| \| \|	untested; hopefully it's right now
*	fix another mips gratuitous-incompatibility bug: ioctl numbers	Rich Felker	2012-08-07	1	-2/+2
\|
*	fix socket.h on mips	Rich Felker	2012-08-05	1	-0/+3
\| \| \| \| \|	why does mips have to be gratuitously incompatible in every possible imaginable way?
*	more stuff lost committing mips dynamic linker	Rich Felker	2012-08-05	1	-2/+2

*	mips dynamic linker support	Rich Felker	2012-08-05	1	-3/+53
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	not heavily tested, but the basics are working. the basic concept is that the dynamic linker entry point code invokes a pure-PIC (no global accesses) C function in reloc.h to perform the early GOT relocations needed to make the dynamic linker itself functional, then invokes __dynlink like on other archs. since mips uses some ugly arch-specific hacks to optimize relocating the GOT (rather than just using the normal DT_REL[A] tables like on other archs), the dynamic linker has been modified slightly to support calling arch-specific relocation code in reloc.h. most of the actual mips-specific behavior was developed by reading the output of readelf on libc.so and simple executable files. i could not find good reference information on which relocation types need to be supported or their semantics, so it's possible that some legitimate usage cases will not work yet.
*	add floating point register saving/restoring to mips setjmp/longjmp	Rich Felker	2012-07-22	1	-1/+1
\| \| \| \| \| \| \|	also fix the alignment of jmp_buf to meet the abi. linux always emulates fpu on mips if it's not present, so enabling this code unconditionally is "safe" but may be slow. in the long term it may be preferable to find a way to disable it on soft float builds.
*	fix broken mips a_fetch_add	Rich Felker	2012-07-12	1	-7/+7
\| \| \| \|	sc was overwriting the result
*	mipsel (little endian) support	Rich Felker	2012-07-12	1	-1/+1
\| \| \| \| \| \|	the fields in the mcontext_t are long long (for no good reason) even on 32-bit mips, so the offset of the instruction pointer (as a word) varies depending on endianness.
*	workaround another sendmsg kernel bug on 64-bit machines	Rich Felker	2012-07-12	1	-0/+7
\| \| \| \| \| \| \| \| \|	the kernel wrongly expects the cmsg length field to be size_t instead of socklen_t. in order to work around the issue, we have to impose a length limit and copy to a local buffer. the length limit should be more than sufficient for any real-world use; these headers are only used for passing file descriptors and permissions between processes over unix sockets.
*	fix redef of sigprocmask constants on mips	Rich Felker	2012-07-12	1	-0/+3
\| \| \| \|	this fix is easier than trying to reorder the header stuff
*	more mips bits-header fixes	Rich Felker	2012-07-12	1	-2/+6
\| \| \| \|	signal handling was very broken because of this
*	fix mips syscalls with long long args	Rich Felker	2012-07-12	1	-1/+1
\| \| \| \| \|	like arm, mips requires 64-bit arguments to be "aligned" on an even register boundary.
*	fix mips mcontext_t structure size	Rich Felker	2012-07-12	1	-1/+5
\| \| \| \| \|	otherwise offs in ucontext_t will be wrong, and break code that inspects or modifies the signal makes (including cancellation code).
*	fix MAP_ANONYMOUS value for mips, remove cruft copied from i386	Rich Felker	2012-07-11	1	-2/+1

*	initial version of mips (o32) port, based on work by Richard Pennington (rdp)	Rich Felker	2012-07-11	29	-0/+2037
	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.
