2014-04-18	It's been a quarter century: we can assume volatile is present with that name.	Philip Guenther

2006-10-10	Preliminary userland bits for OpenBSD/landisk, many things coming from	Miod Vallat
	NetBSD.
2014-04-17	It's been a quarter century: we can assume volatile is present with that name.	Philip Guenther

2014-03-18	Retire hp300, mvme68k and mvme88k ports. These ports have no users, keeping	Miod Vallat
	this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
2014-01-10	match what hppa is doing now (not tested, but should be right)	Theo de Raadt
	ok miod jsing
2014-01-10	correct argument handling; this has been broken since to beginning	Theo de Raadt
	and was writing to wrong memory. ok jsing miod guenther
2013-12-31	Remove #ifdef _REENTRANT code that isn't used here. These days, the code	Mark Kettenis
	handling per-thread errno lives in librthread. ok miod@, espie@
2013-12-24	yup, we do ELF	Theo de Raadt

2013-11-26	1 << 31 cleanup. Eitan Adler pointed out that there has been a	Theo de Raadt
	resurrection of the bad idiom in the tree. sufficient review by miod, kettenis, tedu
2013-11-13	bring in math.h to provide prototypes	Theo de Raadt

2013-11-12	add proto for amd64 case; unify otherwise	Theo de Raadt

2013-09-08	Remove the `let's zero %r2 if %r3 is nonzero' dance. It's been more than 10	Miod Vallat
	years that fork() returns through child_return(), which takes care of zeroing %r2.
2013-07-05	VAX ELF userland bits. Consists mostly of register prefix additions.	Miod Vallat

2013-06-11	bcopy (and family) can check for 0 length, but negative lengths should	Theo de Raadt
	proceed through to crash and show the bug. ok miod
2013-06-05	On second thought, do not use a tcnd instruction to test for divide-by-zero,	Miod Vallat
	as it forces a pipeline synchronization; replace it with a bcnd + unconditional trap, to only synchronize when the trap is needed.
2013-06-05	...also add __modsi3 and __umodsi3, and make these symbols weak by default.	Miod Vallat

2013-06-05	Add __divsi3 and __udivsi3 gcc-compatible routines. Not used by anything yet	Miod Vallat
	(as gcc does not emit code calling them), but will be shortly; belatedly riding the libc minor bump.
2013-04-23	Do a PC-relative relocation for _map rather than going through	Martynas Venckus
	GOTPCREL. Uncovered after the binutils patch where it isn't optimized away at assembly and is forced to go through GOTPCREL. But _map is effectively a local variable. Found with cephes by guenther@. OK guenther@, kettenis@, deraadt@.
2013-04-11	Fix obviously stupid bug in the PIC_{LOAD,STORE} macros when compiling with	Miod Vallat
	-fPIC. Harmless since we build libc -fpic so far.
2013-03-28	Switch libc and libm to use strong aliases rather than weak aliases	Martynas Venckus
	where appropriate. Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@.
2013-02-02	Userland bits for m68k/ELF. Mostly addition of register prefixes to the	Miod Vallat
	assembler instructions, and cope with the few changes in return values location.
2013-01-24	Oops, due to the way return from system calls work, we can not use a delay	Miod Vallat
	slot in the branch to cerror, for the delay slot instruction would also run as part of a successful return. Doh. Fortunately almost nothing in the tree uses brk() or sbrk() anymore... but binaries linked against libiberty.
2013-01-23	The kernel sources mention that the system call entry point is trap #450; the	Miod Vallat
	fact that #128 and #129 may also be used for this purpose was never documented, so there is no reason to have libc use #128. Switch to #450 for consistency.
2013-01-20	Fix PIC_LOAD and PIC_STORE macros to really access the variable, instead of	Miod Vallat
	the GOT pointer. Oops.
2013-01-20	PIC-related code should follow the #ifdef __PIC__ line, not the #else line.	Miod Vallat
	Doh!
2013-01-13	Remove machine-dependent glue for strtorQ, since hppa64 quad-precision	Martynas Venckus
	support has been removed from our compiler a year ago.
2013-01-11	Add END() directives to the various functions.	Miod Vallat
	Make the code PIC-aware when necessary (i.e. invoke other functions through the PLT, and access global data through the GOT). No change for non-PIC compilation.
2013-01-11	Add a bunch of macros to help writing PIC code for libc .S routines. Handles	Miod Vallat
	both -fpic and -fPIC.
2013-01-08	fix __cerror non-weak symbol name	Miod Vallat

2013-01-05	Switch m88k ports to ELF.	Miod Vallat

2012-12-26	Actually invoke the system call in libc's sigreturn() wrapper; went unnoticed	Miod Vallat
	for 15 years or so (sigcode, of course, was correct).
2012-12-22	Make sure the stack is 16-byte aligned otherwise the use of certain SSE	Mark Kettenis
	instructions will fail. ok guenther@
2012-12-05	Remove excessive sys/cdefs.h inclusion	Theo de Raadt
	ok guenther millert kettenis
2012-12-03	Add two missing quad-precision emulation functions: _Qp_cmp and _Qp_cmpe. At	Mark Kettenis
	least the former is emitted by modern versions of GCC.
2012-09-15	Adapt ieee.h, gdtoa and libc to the fact that we don't have 80-bit	Martynas Venckus
	floats on m88k. Agreed by miod@.
2012-09-04	Add support for -fPIC	Theo de Raadt
	ok kettenis
2012-09-04	remove lint leftovers; ok guenther@	Okan Demirmen

2012-09-04	these are no longer used; ok guenther	Theo de Raadt

2012-09-01	Make this __STDC__ aware.	Miod Vallat

2012-08-22	Fix missing PIC -> __PIC__ conversions; ok pascal	Theo de Raadt

2012-08-22	Convert cpp \| as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure cc	Pascal Stumpf
	invocations. This allows us to use the compiler builtin define __PIC__ to check for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot. ok matthew@, conceptually ok kurt@
2012-08-12	Fix almost ten-years old bug in siglongjmp(), which would not restore a signal	Miod Vallat
	mask of zero (because of flawed logic assuming finding zero in the sigjmp_buf signal mask means sigsetjmp was invoked with a zero `savemask' argument). While there, clean comments of all *{set,long}jmp routines, and shave a few instructions by using bcnd insead of cmp + bb to test for zero values. Passes the regress tests, and now devel/libsigsegv configure siglongjmp test will not spin (this test is however flawed as it expects a signal handler declared as running on the sigaltstack and `returning' through siglongjmp to be invoked on the signal stack the next time the signal is raised).
2012-07-03	adapt the NetBSD code to make sigpending work on sh	Jonathan Gray
	ok miod@ kettenis@
2012-07-01	The kernel returns the pending set; this stub has to save it through	Philip Guenthe
	the pointer ok miod@ kettenis@
2012-07-01	make this actually work	Mark Kettenis
	ok miod@
2012-06-25	Do not use <machine/float.h>, that is an deformed BSD-ism.	Theo de Raadt
	It turns out <float.h> is the right file to pull in. ok millert
2012-06-21	__tfork() needs to set the stack address of the new thread in the kernel,	Philip Guenthe
	so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@
2012-04-19	rely on the compiler giving us a built-in alloca. any new architecture	Theo de Raadt
	or compiler we use will. ok millert
2012-04-12	alloca.c cannot be used	Theo de Raadt

2012-04-12	remove rfork(); ok guenther miod	Theo de Raadt
