maya | Unify signbitl implementations.
(Unclear why they were different, it was only the comments that
differed)
Add a comment describing why the generic version works for both 80-bit
and 128-bit double.
|
| 1.18 | 15-Jul-2015 |
pooka | branches: 1.18.16;
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.
problem reported by Robert Gifford on rumpkernel-users
|
| 1.17 | 15-Jul-2015 |
pooka | Remove "objects built from C sources" comments. Everyone can see
they're built from C sources because the source files end in .c (???)
|
| 1.16 | 26-Mar-2011 |
christos | add fpgetprec/fpsetprec
|
| 1.15 | 14-Jan-2010 |
joerg | Move AMD64's bswap64 implementation from libc to src/common and share it
with the kernel.
|
| 1.14 | 06-Dec-2009 |
uebayasi | 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.
|
| 1.13 | 03-Jul-2006 |
drochner | build {frexp,ldexp,modf} in the "compat" subtree
(Drop the modf assembler version. We have the same code in libm.)
(Drop the ldexp inline-assembler version. The same code is in libm as
scalbn; the ldexp there is just a wrapper providing error handling.)
|
| 1.12 | 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.
|
| 1.11 | 04-Mar-2004 |
kleink | branches: 1.11.6;
* 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.
|
| 1.10 | 15-Jan-2004 |
kleink | Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros.
|
| 1.9 | 28-Oct-2003 |
matt | Fix tpyo. (ieee854 -> ieee754)
|
| 1.8 | 25-Oct-2003 |
kleink | Add __infinityf and __infinityl, float respectively long double analogs
of __infinity.
|
| 1.7 | 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.
|
| 1.6 | 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".

| 1.5 | 17-May-2003 |
thorpej | Build _isinfl() and _isnanl().
|
| 1.4 | 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.
|
| 1.3 | 30-Jan-2003 |
fvdl | Add ucontext glue for x86_64.
|
| 1.2 | 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).

longjmp(3) t_sigstack: Use a sigaltstack per handler entry.
longjmp evidently doesn't reset the state of whether the process is
executing on the alternate signal stack. So when we re-enter the
signal handler, the alternate stack appears to be still in use, and
the system chooses the original stack for the second call to the
signal handler -- which trips our assertion asking to verify that the
signal handler is always using an alternate stack.
Not strictly necessary for the signal handler to use an alternate
stack on re-entry, but this makes it clearer that the signal handler
itself is always using the alternate stack so we can verify that the
interrupted code is _not_ in the signal handler.
With this change, the test now passes on aarch64.

signal handler is always using an alternate stack.
Not strictly necessary for the signal handler to use an alternate
stack on re-entry, but this makes it clearer that the signal handler
itself is always using the alternate stack so we can verify that the
interrupted code is _not_ in the signal handler.
With this change, the test now passes on aarch64.

Otherwise, a pending signal may be delivered on the wrong stack when

While here:
- Tidy the code a little bit.
- Sprinkle comments to explain what's going on.
- Use `xorl %eXX,%eXX' instead of `xorq %rXX,%rXX'.

joerg | 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.

remove __SAFE
add long double and hex double support from freebsd.

add the new files to the build. Note I am not bumping libc now, because
these are not used yet.
Merge the int bit with the high fraction bit. Add constants/macros

deal with sparc64 that has 112 bits of mantissa.
make extended precision gdtoa friendly.
int/size_t changes
make this gdtoa friendly.
remove dup definition
use dtoa() instead of returning empty when we don't have extended precision
information.
Fix previous, add forgotten pointer dereference in the call to dtoa().
Add a cheesy workaround marked XXX for the situation where the
strtod() implementation available in the environment does not
handle hex floats.
Discussed with and suggested by christos
From Christos: gdtoa fixes for m68k. M68k ports should build now, but
printing extended precision is a little off.
vax does not have <machine/ieee.h> or long double
It would be nice if the compiler provided something like __IEEE_MATH__
bring in FreeBSD's vfscanf() to gain multi-byte/collation support.
Unfortunately it is too difficult to make vfwscanf and this share
the same code like I did with printf, because for string parsing
the code is too different.

lib/libc/arch/x86_64/gen/swapcontext.S: revision 1.4
Don't clobber callee save registers r12 & r13 in swapcontext. They
were saved in the stack, but the subsequent swapcontext would return
to the earlier stack frame and never restore them. Fixes puffs
with default compiler flags on amd64.
Thanks to Mihai Chelaru for providing access to an amd64 machine
for debugging this problem.
