Revision	Date	Author	Comments
1.9	24-Nov-2021	thorpej	Decorate the SuperH signal trampoline with the appropriate .cfi directives to allow exception unwind / backtrace across a signal handler.
1.8	31-Oct-2021	thorpej	Tidy up how __sigaction14_sigtramp.c is added to SRCS.
1.7	22-Mar-2017	chs	provide a common softfloat fenv implemenation and use it for softfloat builds. restore ABI compatibility with previous releases for ieeefp.h on sh3. add namespace.h protection for all the fenv interfaces. use MKSOFTFLOAT on sh3 instead of assuming softfloat. standardize on comparing MKSOFTFLOAT with "no". remove the arm-specific softfloat fenv code (which also had several bugs). fix logic errors in the arm hardfloat feraiseexcept() and feupdateenv().
1.6	17-Jun-2006	uwe	branches: 1.6.68; 1.6.72; G/c KMSRCS and KMINCLUDES now that we have common/lib/libc
1.5	15-Sep-2005	uwe	Switch arch/sh3/sys to the new compat code layout.
1.4	23-Nov-2003	uwe	Implement siginfo for sh3.
1.3	10-Jul-2002	thorpej	Enable the libc-provided signal trampoline. The old __sigaction14 entry point has been replaced by the new __sigaction14() which is a wrapper around the __sigaction_sigtramp system call (which is itself not directly exposed outside of libc). No shared library version change is necessary; no new symbols are exposed outside of libc.
1.2	06-Jun-2000	tsubai	branches: 1.2.4; Add softfloat glue for sh3.

1.6.68.1	26-Apr-2017	pgoyette	Sync with HEAD
1.11	12-Sep-2013	joerg	Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small vs big PIC mode. Retire -DPIC and -DBIGPIC.

1.9	06-Jan-2006	uwe	branches: 1.9.40; Drop unnecessary nops.
1.8	06-Jan-2006	uwe	Change cerror to take errno in r4, instead of r0. In PIC code fetch cerror address from GOT to avoid unresolved text relocations in shared libraries. Hide the code to jump to cerror inside JUMP_CERROR macro. Change syscall code to use JUMP_CERROR. Die text relocations! DIE!
1.7	25-Dec-2005	uwe	Be consistent about macro indentation. Indent delay slot instructions. Whitespace changes only, same binary code produced.
1.6	07-Aug-2003	agc	branches: 1.6.6; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.5	01-Jul-2003	marcus	Generate proper PIC code for libc_pic.a.
1.4	26-May-2002	wiz	Revert previous: .S files are currently compiled with -traditional-cpp, so __STDC__ is _not_ always defined.
1.3	26-May-2002	wiz	__STDC__ is always defined on NetBSD.
1.2	14-Jan-2002	thorpej	* Add WSYSCALL() to SYS.h, which creates a system call with an internal name and a weak alias for the name. * Add a WEAKASM syscall list, and process it. * Make sysarch() have an internal name (_sysarch()).

1.1	24-Nov-2021	thorpej	Decorate the SuperH signal trampoline with the appropriate .cfi directives to allow exception unwind / backtrace across a signal handler.
1.1	15-Mar-2006	kleink	Add strtof(3) and strtold(3); welcome libc 12.137.
1.1	25-Jan-2006	kleink	Add machine-dependent definitions for gdtoa.
1.1	25-Jan-2006	kleink	Add machine-dependent definitions for gdtoa.
1.26	20-Jan-2014	joerg	Use fabs_ieee754.c.
1.25	06-Dec-2009	uebayasi	branches: 1.25.6; 1.25.12; Rename ${SRCS.{alpha,arm,...}.gen} to ${LSRCS.{alpha,arm,...}.gen} because they ended up in ${LSRCS}, not ${SRCS}. ${SRCS.*} namespace will be used for more useful things. No functional changes intended.
1.24	28-Jun-2006	drochner	build frexp/ldexp/modf in the "compat" part (code is identical) (These are the easy cases where no assembler implementations exist.)
1.23	17-Jun-2006	uwe	G/c KMSRCS and KMINCLUDES now that we have common/lib/libc
1.22	02-Jun-2006	mrg	remove GCC2 support
1.21	07-Apr-2006	mrg	retire HAVE_GCC3/HAVE_GCC4 and introduce HAVE_GCC that is set to 2, 3 or 4.
1.20	15-Oct-2005	uwe	_setjmp and _longjmp are not compat functions. Noticed by Havard Eidnes.
1.19	15-Sep-2005	uwe	Add lint stubs for __setjmp14 and __sigsetjmp14.
1.18	15-Sep-2005	uwe	Switch arch/sh3/gen to the new compat code layout.
1.17	15-Apr-2005	kleink	Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit. IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.
1.16	04-Mar-2004	kleink	branches: 1.16.6; * Turn isinf(3) and isnan(3) into C99-style macros. * Make it possible for ports to override these (i.e., VAX). * Remove isnanl(), which was internal to libc only.
1.15	22-Feb-2004	uwe	In gcc3 world the "millicode" must be provided by libgcc*.a, so don't include it in libc.
1.14	15-Jan-2004	kleink	Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros.
1.13	25-Oct-2003	kleink	Add __infinityf and __infinityl, float respectively long double analogs of __infinity.
1.12	24-Oct-2003	kleink	* Since there is no single portable IEEE 754 format for a long double, keep a common implementation of isinfl() and isnanl() to be used by platforms where `long double' == `double'; move others into machine-dependent code. * In due course, consider __VFP_FP__ on arm.
1.11	01-Aug-2003	lukem	Rework how dependency generation is performed: * DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204. * To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx * If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES * Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} .d depend upon ${DPSRCS} Deprecate the (short lived) DEPENDSRCS Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries. Tested with "make -j 8 distribution" and "make distribution".
1.10	17-May-2003	thorpej	Build _isinfl() and _isnanl().
1.9	12-May-2003	kleink	Rename ieee754_function.c to function_ieee754.c, following the convention used in exec_format.c, loadfile_format.c, subsys_machdep.c etc. Per discussion with Christos.
1.8	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.7	05-Sep-2002	msaitoh	Add __movstr_i4_{odd,even} for -m4. Written by SHIMIZU Ryo.
1.6	02-Apr-2002	thorpej	Remove non-existent ldexp.c from SRCS.
1.5	19-Feb-2002	simonb	Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only).

1.6	22-Mar-2012	he	Follow the pattern from powerpc, make lint happy.
1.5	24-Feb-2011	joerg	branches: 1.5.4; Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.

[pointed out by thorpej, thanks!] If we want to remove sigcontext support from userland at least now there is less work to do so.

1.1.2.3	02-Oct-2002	thorpej	libc: Internally rename __sigaction14 to __libc_sigaction14. Provide a weak alias of __sigaction14 -> __libc_sigaction14. libpthread: Use __libc_sigaction14 to actually register the signal handler, rather than using __sigaction_sigtramp() directly with a hard-coded trampoline version. While we don't actually use the libc trampoline, we want to avoid depending on any COMPAT_* kernel options down the road (this is already the case for the VAX port). Be explicit about which version of the signal interface we're interposing (...14), and build pthread_sig.c with __LIBC12_SOURCE__ (required to get the libc-internal interfaces).

1.6	07-Feb-2017	kamil	Mark exect(3) obsolete and bind it to plain execve(2) on all platforms The original exect(2) from BSD4.2 was enabling bit for tracing (single-step mode) and calling execve(2). The purpose of it was to generate a signal for a tracer once the application will change its image to a new program. This approach no longer works as: - exect(2) traces (single-steps) libc and it requires hundreds or thousands steps before entering a new image - it's vax and x86 specific code - this functionality has been moved to the kernel - once a process is traced it will generate SIGTRAP with si_code TRAP_EXEC and route it to its debugger - the side effects and unportability make this interface unusable - there are no known users of this interface - it apparently never worked better since day0 of NetBSD ("day0 bug") Users are requested to move to other execve(2) variants. Calling current execve(2) as it is the most similar behavior to this one from BSD4.2. Discussed several times on mailing lists and in PR/51700. Add warning to exect(3) telling about marking this function obsolete. This function is prepared to be removed in next libc major bump. Sponsored by <The NetBSD Foundation>
