* fix signal.h breakage from moving stack_t to arch-specific bitsRich Felker2014-03-181-6/+6
| | | | | | in the previous changes, I missed the fact that both the prototype of the sigaltstack function and the definition of ucontext_t depend on stack_t.
* fix mips stack_tRich Felker2014-03-181-1/+1
| | | | like almost everything on mips, this is gratuitously different.
* move signal.h definition of stack_t to arch-specific bitsRich Felker2014-03-181-0/+6
| | | | | it's different at least on mips. mips version will be fixed in a separate commit to show the change.
* remove useless and incorrect uc_regspace member from mips ucontext_tRich Felker2014-03-181-1/+0
| | | | | | this seems to have been copied erroneously from the arm version of the file. it's fairly harmless but it's a mistake and better to fix now than later.
* fix _NSIG and SIGRTMAX on mipsRich Felker2013-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | | a mips signal mask contains 128 bits, enough for signals 1 through 128. however, the exit status obtained from the wait-family functions only has room for values up to 127. reportedly signal 128 was causing kernelspace bugs, so it was removed from the kernel recently; even without that issue, however, it was impossible to support it correctly in userspace. at the same time, the bug was masked on musl by SIGRTMAX incorrectly yielding 64 on mips, rather than the "correct" value of 128. now that the _NSIG issue is fixed, SIGRTMAX can be fixed at the same time, exposing the full range of signals for application use. note that the (nonstandardized) libc _NSIG value is actually one greater than the max signal number, and also one greater than the kernel headers' idea of _NSIG. this is the reason for the discrepency with the recent kernel changes. since reducing _NSIG by one brought it down from 129 to 128, rather than from 128 to 127, _NSIG/8, used widely in the musl sources, is unchanged.
* fixup mcontext stuff to expost gregset_t/fpregset_t as appropriateRich Felker2012-11-251-1/+19

* sigcontext/mcontext cleanup for arch-specific bitsRich Felker2012-11-231-11/+11
| | | | | | | | | | | | | | | | | with these changes, the members/types of mcontext_t and related stuff should closely match the glibc definitions. unlike glibc, however, the definitions here avoid using typedefs as much as possible and work directly with the underlying types, to minimize namespace pollution from signal.h in the default (_BSD_SOURCE) profile. this is a first step in improving compatibility with applications which poke at context/register information -- mainly debuggers, trace utilities, etc. additional definitions in ucontext.h and other headers may be needed later. if feature test macros are used to request a conforming namespace, mcontext_t is replaced with an opaque structure of the equivalent size and alignment; conforming programs cannot examine its contents anyway.
* fix up leftover, incorrect NSIG definitions in arch-specific signal.hRich Felker2012-11-231-1/+0

* add back NSIG, removed from powerpc in last commit, but for all archsRich Felker2012-11-211-0/+2
| | | | | | | | unlike the previous definition, NSIG/_NSIG is supposed to be one more than the highest signal number. adding this will allow simplifying libc-internal code that makes signal-related syscalls, which can be done as a later step. some apps might use it too; while this usage is questionable, it's at least not insane.
* fix redef of sigprocmask constants on mipsRich Felker2012-07-121-0/+3
| | | | this fix is easier than trying to reorder the header stuff
* more mips bits-header fixesRich Felker2012-07-121-2/+6
| | | | signal handling was very broken because of this
* fix mips mcontext_t structure sizeRich Felker2012-07-121-1/+5
| | | | | otherwise offs in ucontext_t will be wrong, and break code that inspects or modifies the signal makes (including cancellation code).
* initial version of mips (o32) port, based on work by Richard Pennington (rdp)Rich Felker2012-07-111-0/+73
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.
