2012-12-06	add more arch-specific MAP_ macros to bits/mman.h	rofl0r	-0/+4
	these are also needed by qemu.
2012-12-06	remove MAP_32 from non-x86 archs	rofl0r	-1/+0
	both kernel and glibc define it only on x86(_64).
2012-12-06	add MAP_NORESERVE to bits/mman.h	rofl0r	-0/+1
	this is needed for qemu, and since it differs for each arch it can't be circumvented easily by using a macro in CFLAGS.
2012-11-25	fixup mcontext stuff to expost gregset_t/fpregset_t as appropriate	Rich Felker	-0/+1

2012-11-25	remove microblaze user.h incorrectly copied from arm	Rich Felker	-40/+1

2012-11-23	sigcontext/mcontext cleanup for arch-specific bits	Rich Felker	-15/+15
	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.
2012-11-23	fix up leftover, incorrect NSIG definitions in arch-specific signal.h	Rich Felker	-1/+0

2012-11-21	add back NSIG, removed from powerpc in last commit, but for all archs	Rich Felker	-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.
2012-11-18	fix breakage from introducing bits header for sys/io.h	Rich Felker	-0/+0
	apparently some other archs have sys/io.h and should not break just because they don't have the x86 port io functions. provide a blank bits/io.h everywhere for now.
2012-11-18	fcntl.h: O_SEARCH was missing for powerpc	rofl0r	-3/+0
	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.
2012-10-19	fix struct stat size/padding on microblaze	Rich Felker	-1/+2

2012-10-18	inline syscalls for microblaze	Rich Felker	-0/+97

2012-10-18	better support for reverse-endian variants of arm/mips/microblaze	Rich Felker	-0/+4
	these macros are supported by more compilers
2012-10-15	microblaze TLS relocation support, completely untested	Rich Felker	-0/+6

2012-10-15	add support for TLS variant I, presently needed for arm and mips	Rich Felker	-0/+2
	despite documentation that makes it sound a lot different, the only ABI-constraint difference between TLS variants II and I seems to be that variant II stores the initial TLS segment immediately below the thread pointer (i.e. the thread pointer points to the end of it) and variant I stores the initial TLS segment above the thread pointer, requiring the thread descriptor to be stored below. the actual value stored in the thread pointer register also tends to have per-arch random offsets applied to it for silly micro-optimization purposes. with these changes applied, TLS should be basically working on all supported archs except microblaze. I'm still working on getting the necessary information and a working toolchain that can build TLS binaries for microblaze, but in theory, static-linked programs with TLS and dynamic-linked programs where only the main executable uses TLS should already work on microblaze. alignment constraints have not yet been heavily tested, so it's possible that this code does not always align TLS segments correctly on archs that need TLS variant I.
2012-10-04	dynamic-linked TLS support for everything but dlopen'd libs	Rich Felker	-1/+5
	currently, only i386 is tested. x86_64 and arm should probably work. the necessary relocation types for mips and microblaze have not been added because I don't understand how they're supposed to work, and I'm not even sure if it's defined yet on microblaze. I may be able to reverse engineer the requirements out of gcc/binutils output.
2012-09-29	microblaze port	Rich Felker	-0/+1962
	based on initial work by rdp, with heavy modifications. some features including threads are untested because qemu app-level emulation seems to be broken and I do not have a proper system image for testing.
