J.T. Conklin's latest version of the Sun math library. -- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have. The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments Reviewed by: jkh Submitted by: jtc

Now that we do not need to do runtime detection for the broken default fp emulator, stop doing the runtime selection of hardware or emulated floating point operations on i386. Note that I have not suppressed the duplicate compiles yet. While here, fix the alpha.

Avoid raising unexpected floating point exceptions in libm When using clang with x86_64 CPUs that support AVX, some floating point transformations may raise exceptions that would not have been raised by the original code. To avoid this, use the -fp-exception-behavior=maytrap flag, introduced in clang 10.0.0. In particular, this fixes a number of test failures with ctanhf(3) and ctanf(3), when libm is compiled with -mavx. An unexpected FE_INVALID exception is then raised, because clang emits vdivps instructions to perform certain divides. (The vdivps instruction operates on multiple single-precision float operands simultaneously, but the exceptions may be influenced by unused parts of the XMM registers. In this particular case, it was calculating 0 / 0, which results in FE_INVALID.) If -fp-exception-behavior=maytrap is specified however, clang uses vdivss instructions instead, which work on one operand, and should not raise unexpected exceptions.

Use a builtin where possible in msun Some of the functions in msun can be implemented using a compiler builtin function to generate a small number of instructions. Implement this support in fma, fmax, fmin, and sqrt on arm64. Care must be taken as the builtin can be implemented as a function call on some architectures that lack direct support. In these cases we need to use the original code path. As we don't set errno on failure build with -fno-math-errno so the toolchain doesn't convert a builtin into a function call when it detects a failure, e.g. gcc will add a call to sqrt when the input is negative leading to an infinite loop.

Fix two bugs in the signbit() macro, which was implemented last year: - It was added to libc instead of libm. Hopefully no programs rely on this mistake. - It didn't work properly on large long doubles because its argument was converted to type double, resulting in undefined behavior.

Implementations of cexpl() The change implements cexpl() for both ld80 and ld128 architectures. Testing was done on x86_64 and aarch64 systems. Along the way sincos[fl]() use an optimization that reduces the argument to being done one rather than twice. This optimization actually pointed to a bug in the ld128 version of sincosl(), which is now fixed. In addition, the minmax polynomial coefficients for sincosl() have been updated.

Only provide one copy of the math functions. If we provide a MD function, do not also provide a __generic_XXX version as well. This is how we used to runtime select the generic vs i387 versions on the i386 platform. This saves a pile of #defines in the src/math_private.h file to undo the __generic_XXX renames in some of the *.c files.

J.T. Conklin's latest version of the Sun math library. -- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have. The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments Reviewed by: jkh Submitted by: jtc

Add an implementation of fenv.h intended for platforms that lack an FPU and use softfloat. Thanks to Ian Lepore for testing and debugging this patch. The fenv regression tests pass (at least for Ian's arm chip) with this change.

Added new bsd.incs.mk which handles installing of header files via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to handle symlinking include files. Allow for multiple groups of include files to be installed, with the powerful INCSGROUPS knob. Documentation to follow. Added standard `includes' and `incsinstall' targets, use them in Makefile.inc1. Headers from the following makefiles were not installed before (during `includes' in Makefile.inc1): kerberos5/lib/libtelnet/Makefile lib/libbz2/Makefile lib/libdevinfo/Makefile lib/libform/Makefile lib/libisc/Makefile lib/libmenu/Makefile lib/libmilter/Makefile lib/libpanel/Makefile Replaced all `beforeinstall' targets for installing includes with the INCS stuff. Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS, and for compatibility with NetBSD. Similarly for INCOWN, INCGRP, and INCMODE. Consistently use INCLUDEDIR instead of /usr/include. gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes were only lightly tested due to the missing contrib/libstdc++-v3. I fully tested the pre-WIP_GCC31 version of this patch with the contrib/libstdc++.295 stuff. These changes have been tested on i386 with the -DNO_WERROR "make world" and "make release".

Implementations of cexpl() The change implements cexpl() for both ld80 and ld128 architectures. Testing was done on x86_64 and aarch64 systems. Along the way sincos[fl]() use an optimization that reduces the argument to being done one rather than twice. This optimization actually pointed to a bug in the ld128 version of sincosl(), which is now fixed. In addition, the minmax polynomial coefficients for sincosl() have been updated.

The logb() functions are not just ieee754 "test" functions, but are standard in C99 and POSIX.1-2001+. They are also not deprecated, since apart from being standard they can handle special args slightly better than the ilogb() functions. Move their documentation to ilogb.3. Try to use consistent and improved wording for both sets of functions. All of ieee854, C99 and POSIX have better wording and more details for special args. Add history for the logb() functions and ilogbl(). Fix history for ilogb().

J.T. Conklin's latest version of the Sun math library. -- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have. The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments Reviewed by: jkh Submitted by: jtc
