Kito Cheng via Newlib d572c4482b RISC-V: Support Zfinx/Zdinx extension.
Zfinx/Zdinx are new extensions ratified in 2022, it similar to F/D extensions,
support hard float operation for single/double precision, but the difference
between Zfinx/Zdinx and F/D is Zfinx/Zdinx is operating under general purpose
registers rather than dedicated floating-point registers.

This patch improve the hard float support detection for RISC-V port, so
that Zfinx/Zdinx can have better/right performance.

Hau Hsu 97d483c2f8 RISC-V: Use the new libm code if possible
Set  __OBSOLETE_MATH_DEFAULT to 0 if 'd' extension is supported (i.e.
__riscv_flen == 64).

Base on the comment for  __OBSOLETE_MATH_DEFAULT:

> ... it assumes that the toolchain has ISO C99 support (hexfloat
> literals, standard fenv semantics), the target has IEEE-754 conforming
> binary32 float and binary64 double (not mixed endian) representation,
> standard SNaN representation, double and single precision arithmetics
> has similar latency and it has no legacy SVID matherr support, only
> POSIX errno and fenv exception based error handling.

Keith Packard via Newlib 45efe659b8 libm: Set math_errhandling to match library and hardware [v2]
math_errhandling is specified to contain two bits of information:

 1. MATH_ERRNO     -- Set when the library sets errno
 2. MATH_ERREXCEPT -- Set when math operations report exceptions

MATH_ERRNO should match whether the original math code is compiled in
_IEEE_LIBM mode and the new math code has WANT_ERRNO == 1.

MATH_ERREXCEPT should match whether the underlying hardware has
exception support. This patch adds configurations of this value for
RISC-V, ARM, Aarch64, x86 and x86_64 when using HW float.

Jeff Johnston 1787e9d033 AMD GCN Port contributed by Andrew Stubbs <ams@codesourcery.com>
Add support for the AMD GCN GPU architecture.  This is primarily intended for
use with OpenMP and OpenACC offloading.  It can also be used for stand-alone
programs, but this is intended mostly for testing the compiler and is not
expected to be useful in general.

The GPU architecture is highly parallel, and therefore Newlib must be
configured to use dynamic re-entrancy, and thread-safe malloc.

The only I/O available is a via a shared-memory interface provided by libgomp
and the gcn-run tool included with GCC.  At this time this is limited to
stdout, argc/argv, and the return code.

Szabolcs Nagy 393a1cb4ea Move __HAVE_FAST_FMA to math_config.h
Define it consistently with other HAVE_* macros that only affect code
using math_config.h.  This is also closer to the Arm Optimized Routines
code.

Szabolcs Nagy e5791079c6 New log implementation
The new implementations are provided under !__OBSOLETE_MATH, it uses
ISO C99 code.  With default settings the worst case error in nearest
rounding mode is 0.519 ULP with inlined fma and fma contraction.  It uses
a 2 KB lookup table, on aarch64 .text+.rodata size of libm.a is increased
by 1703 bytes.  The w_log.c wrapper is disabled since error handling is
inline in the new code.

New __HAVE_FAST_FMA and __HAVE_FAST_FMA_DEFAULT feature macros were
added to enable selecting between the code path that uses fma and the
one that does not.  Targets supposed to set __HAVE_FAST_FMA_DEFAULT
if they have single instruction fma and the compiler can actually
inline it (gcc has __FP_FAST_FMA macro but that does not guarantee
inlining with -fno-builtin-fma).

Improvements on Cortex-A72:
latency: 1.9x
thruput: 2.3x

Thomas Preudhomme 7d09d0e261 Disable powf/log2?f/exp2?f optimization for single-precision Arm FPU
New optimized powf, logf, log2f, expf and exp2f yield worse performance
on Arm targets with only single precision instructions because the
double precision arithmetic is then implemented via softfloat routines.
This patch uses the old implementation when double precision
instructions are not available on Arm targets.

Testing: Built newlib with GCC's rmprofile Arm multilibs and compared
before/after -> only the above functions are changed and calls to them
(name change from logf to __ieee754_logf and similar). Testing the
changed function on a panel of values yields the same result before the
original patches to improve them and after this one. Double checking the
performance by looping the same panel of values being tested on Arm
Cortex-M4 does show the performance regression is fixed.

Szabolcs Nagy c156098271 New expf, exp2f, logf, log2f and powf implementations
Based on code from https://github.com/ARM-software/optimized-routines/

This patch adds a highly optimized generic implementation of expf,
exp2f, logf, log2f and powf.  The new functions are not only
faster (6x for powf!), but are also smaller and more accurate.
In order to achieve this, the algorithm uses double precision
arithmetic for accuracy, avoids divisions and uses small table
lookups to minimize the polynomials.  Special cases are handled
inline to avoid the unnecessary overhead of wrapper functions and
set errno to POSIX requirements.

The new functions are added under newlib/libm/common, but the old
implementations are kept (in newlib/libm/math) for non-IEEE or
pre-C99 systems.  Targets can enable the new math code by defining
__OBSOLETE_MATH_DEFAULT to 0 in newlib/libc/include/machine/ieeefp.h,
users can override the default by defining __OBSOLETE_MATH.
Currently the new code is enabled for AArch64 and AArch32 with VFP.
Targets with a single precision FPU may still prefer the old
implementation.

arm/thumb/v7-a/nofp: -878
arm/thumb/v7-a+fp/hard: -864
