make an arch directory in libc, and move all machine dirs into it

Tidy up how __sigaction14_sigtramp.c is added to SRCS.

Decorate the i386 signal trampoline with CFI attributes easing unwinding

Now, the unwinders (in backtrace(3) and similar) can unwind properly
the stack from a signal handler.

Don't include sigtramp or foocontext routines in rumprun mode. They won't
work (since a rump kernel does not provide NetBSD _lwp syscalls nor
signals), but they cause unwanted symbols to be pulled in when the
resulting libc is linked.

G/c KMSRCS and KMINCLUDES now that we have common/lib/libc

compat core reorg.

Add __sigtramp2.S

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entry point has been replaced by the new __sigaction14() which is a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.

branches: 1.16.2;
Add __syscall.S to arch/i386/gen/Makefile.inc along with all the other
sys .S files. Remove from arch/i386/Makefile.inc since it doesn't belong
there.

KMSRCS is different from SRCS. Put __syscall.S in latter.

Move __syscall.S to the arch specific Makefile.inc's where it is
implemented.

SYS.h was nuked from libkern

Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.

A better fix for the stub-in-other-module problem:

branches: 1.13.2;
Add PIC_PROLOGUE before the PLT call to cerror. ELF dynamic linking needs
this.

* On architectures using ELF, and conditionally on those in transition, rename
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

Consistency: distinguish between PSEUDO() and PSEUDO_NOERROR().

Added new macros:
SYSTRAP(x): Expands to the code used to call syscall x.
This is used to simplify other macros.

SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall
that can never fail.

RSYSCALL_NOERROR(x): Like RSYSCALL except that "x" is a syscall
that can never fail.

Removed unused CALL macro

Added macros definitions for use with ANSI preprocessors.

Remove "objects built from C sources" comments. Everyone can see
they're built from C sources because the source files end in .c (???)

add fpgetprec/fpsetprec

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.

Build just the compatibility versions of frexp()/ldexp()/modf(), the

_setjmp and _longjmp are not compat functions. Noticed by Havard Eidnes

compat core reorg.

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.

branches: 1.20.6;
* 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.

Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros.

Add __infinityf and __infinityl, float respectively long double analogs
of __infinity.

* 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.

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".

Build _isinfl() and _isnanl().

Rename ieee754_function.c to function_ieee754.c, following the convention

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).

<machine/asm.h>; Also syscalls should be protected using the SYSLIBC_SCCS
define not LIBC_SCCS

Smaller & Faster.

Use RCSID macro.

Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change
th LIBC_RCS, the entire source tree should be updated at once.
Remove && !defined(lint) from conditionals around rcs id's. No one is
ever going to pass a *.s file through lint.

Provide an assembly language version of labs().
Since ints and longs are both 32 bits on a i386, we could alias abs()
and labs() together as mycroft did with memmove()/memcpy(), but I'm
waiting on an interpretation ruling to see if it is legal.

make an arch directory in libc, and move all machine dirs into it

If SRCS contains any .S files then remove the corresponding .c file from
SRCS and add to LSRCS (for lint).
Change the 'string' Makefiles so that the arch/*/string/Makefile.inc
need only specify the .S files for that architecture and not the .c
files for all the files they don't override.

Change all archs so that strchr.[cS] and strrchr.[cS] exist and generate
duplicate symbols for index() and rindex().
libc and kernel build ok for affected archs (i386, amd64, vax, sun3,
evbmips-eb) all seem ok.
(vax might lose an asm index() - but comments imply it is worse than the C)

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".

Changed the test that determines whether or not source and destination
memory regions are "potentially overlapping" to a test that determines
that the regions are actually overlapping. Because the code for the
overlapping case is seven instructions longer, this signifcantly
improves performance in the average case.
