2012-07-03	jmp_buf overhaul fixing several issues	Rich Felker	-1/+1
	on arm, the location of the saved-signal-mask flag and mask were off by one between sigsetjmp and siglongjmp, causing incorrect behavior restoring the signal mask. this is because the siglongjmp code assumed an extra slot was in the non-sig jmp_buf for the flag, but arm did not have this. now, the extra slot is removed for all archs since it was useless. also, arm eabi requires jmp_buf to have 8-byte alignment. we achieve that using long long as the type rather than with non-portable gcc attribute tags.
2012-06-23	update syscall defs to latest kernel ones	Rich Felker	-0/+4
	patch submitted by Kristian L. <email@thexception.net>
2012-06-20	proper error handling for fcntl F_GETOWN on modern kernels	Rich Felker	-0/+3
	on old kernels, there's no way to detect errors; we must assume negative syscall return values are pgrp ids. but if the F_GETOWN_EX fcntl works, we can get a reliable answer.
2012-05-24	fix arm syscall.h to reflect which syscalls actually exist (on EABI)	Rich Felker	-22/+0

2012-05-22	fix missing _BSD_SOURCE support in bits/*.h	Rich Felker	-4/+4
	this is actually rather ugly, and would get even uglier if we ever want to support further feature test macros. at some point i may factor the bits headers into separate files for C base, POSIX base, and nonstandard extensions (the only distinctions that seem to matter now) and then the logic for which to include can go in the main header rather than being duplicated for each arch. the downside of this is that it would result in more files having to be opened during compilation, so as long as the ugliness does not grow, i'm inclined to leave it alone for now.
2012-04-24	use signed char rather than plain char for int8_t	Rich Felker	-4/+4
	otherwise this BADLY breaks if -funsigned-char is passed to gcc
2012-04-15	move F_DUPFD_CLOEXEC out of bits	Rich Felker	-2/+0
	fcntl values 1024 and up are universal, arch-independent. later I'll add some of the other linux-specific ones for notify, leases, pipe size, etc. here too.
2012-04-15	add F_SETSIG and F_GETSIG (linux specific) to fcntl.h	Rich Felker	-0/+2
	F_* is in the reserved namespace so no feature test is needed
2012-03-21	fix DECIMAL_DIG definitions	Rich Felker	-0/+2
	DECIMAL_DIG is not the same as LDBL_DIG type_DIG is the maximimum number of decimal digits that can survive a round trip from decimal to type and back to decimal. DECIMAL_DIG is the minimum number of decimal digits required in order for any floating point type to survive the round trip to decimal and back, and it is generally larger than LDBL_DIG. since the exact formula is non-trivial, and defining it larger than necessary may be legal but wasteful, just define the right value in bits/float.h.
2012-02-25	use __attribute__((const)) on arm __pthread_self function	Rich Felker	-1/+3

2012-02-15	add float_t and double_t to math.h	Rich Felker	-0/+3

2012-02-09	replace bad cancellation cleanup abi with a sane one	Rich Felker	-6/+0
	the old abi was intended to duplicate glibc's abi at the expense of being ugly and slow, but it turns out glib was not even using that abi except on non-gcc-compatible compilers (which it doesn't even support) and was instead using an exceptions-in-c/unwind-based approach whose abi we could not duplicate anyway without nasty dwarf2/unwind integration. the new abi is copied from a very old glibc abi, which seems to still be supported/present in current glibc. it avoids all unwinding, whether by sjlj or exceptions, and merely maintains a linked list of cleanup functions to be called from the context of pthread_exit. i've made some care to ensure that longjmp out of a cleanup function should work, even though it is not required to. this change breaks abi compatibility with programs which were using pthread cancellation, which is unfortunate, but that's why i'm making the change now rather than later. considering that most pthread features have not been usable until recently anyway, i don't see it as a major issue at this point.
2011-10-17	fix some details in ugly stuff that doesn't belong in libc	Rich Felker	-6/+6
	patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
2011-10-15	don't define wchar_t on c++	Rich Felker	-0/+2
	it's a keyword in c++ (wtf). i'm not sure this is the cleanest solution; it might be better to avoid ever defining __NEED_wchar_t on c++. but in any case, this works for now.
2011-10-05	fix fcntl O_* flags for arm	Rich Felker	-4/+4
	no idea why these 4 are permuted and the rest are standard/generic
2011-10-01	typo (copy 2) in arm reloc.h	Rich Felker	-1/+1

2011-10-01	typo in arm reloc.h	Rich Felker	-1/+1

2011-10-01	first attempt at arm dynamic linking	Rich Felker	-0/+26

2011-09-22	"optimize" arm __pthread_self	Rich Felker	-4/+1
	actually this is just to avoid gcc being stupid and refusing to inline the function version, even when the size cost is essentially identical whether it's inlined or not.
2011-09-21	update syscalls with off_t arguments to handle argument alignment, if needed	Rich Felker	-1/+2
	the arm syscall abi requires 64-bit arguments to be aligned on an even register boundary. these new macros facilitate meeting the abi requirement without imposing significant ugliness on the code.
2011-09-19	fix the definition of struct statvfs to match lsb abi	Rich Felker	-15/+6
	at the same time, make struct statfs match the traditional definition and make it more useful, especially the fsid_t stuff.
2011-09-19	cleanup redundancy in bits/signal.h versions	Rich Felker	-121/+12

2011-09-19	fix the type of wchar_t on arm; support wchar_t varying with arch	Rich Felker	-6/+6
	really wchar_t should never vary, but the ARM EABI defines it as an unsigned 32-bit int instead of a signed one, and gcc follows this nonsense. thus, to give a conformant environment, we have to follow (otherwise L""[0] and L'\0' would be 0U rather than 0, but the application would be unaware due to a mismatched definition for WCHAR_MIN and WCHAR_MAX, and Bad Things could happen with respect to signed/unsigned comparisons, promotions, etc.). fortunately no rules are imposed by the C standard on the relationship between wchar_t and wint_t, and WEOF has type wint_t, so we can still make wint_t always-signed and use -1 for WEOF.
2011-09-19	fix incorrect long double parameters on arm (and other future ports)	Rich Felker	-10/+10
	this was the cause of crashes in printf when attempting to print floating point values.
2011-09-18	initial commit of the arm port	Rich Felker	-0/+2076
	this port assumes eabi calling conventions, eabi linux syscall convention, and presence of the kernel helpers at 0xffff0f?0 needed for threads support. otherwise it makes very few assumptions, and the code should work even on armv4 without thumb support, as well as on systems with thumb interworking. the bits headers declare this a little endian system, but as far as i can tell the code should work equally well on big endian. some small details are probably broken; so far, testing has been limited to qemu/aboriginal linux.
