* 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.
* 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.
* x32: fix struct statfsrofl0r2014-03-171-2/+4
| | | | | the omission of the padding was uncovered by the latest regression statvfs regression test added to libc-test.
* move struct semid_ds to from shared sys/sem.h to bitsRich Felker2014-03-111-0/+16
| | | | | | | | | | | | the definition was found to be incorrect at least for powerpc, and fixing this cleanly requires making the definition arch-specific. this will allow cleaning up the definition for other archs to make it more specific, and reversing some of the ugliness (time_t hacks) introduced with the x32 port. this first commit simply copies the existing definition to each arch without any changes. this is intentional, to make it easier to review changes made on a per-arch basis.
* x32: fix sysinfo()rofl0r2014-03-061-0/+47
| | | | | | | | the kernel uses long longs in the struct, but the documentation says they're long. so we need to fixup the mismatch between the userspace and kernelspace structs. since the struct offers a mem_unit member, we can avoid truncation by adjusting that value.
* make the x32 port use the correct ld-musl-x32.path filenameRich Felker2014-02-231-1/+1
| | | | | previously it was wrongly using the x86_64 one, precluding having both x32 and x86_64 libs present on the same system.
* fix x32 syscall arch.h timespec fixup coderofl0r2014-02-231-53/+49
| | | | | | | | it's legal to call the __syscall functions with more arguments than necessary, and the __syscall_cp cancel dummy impl. does just that. thus we must insert the switch for all possible syscalls numbers into all of the syscallN inline functions.
* fix some issues in x32 syscall_cp_fixuprofl0r2014-02-231-11/+8
| | | | | | - the nanosleep fixup "fixed" the second timespec* argument erroneusly. - the futex fixup was missing the check for FUTEX_WAIT. - general cleanup using a macro.
* mostly-cosmetic fixups to x32 port mergeRich Felker2014-02-231-1/+1
