2018-10-10Implement nanl in newlib onlyCorinna Vinschen1-0/+6
Drop Cygwin-specific nanl in favor of a generic implementation in newlib. Requires GCC 3.3 or later. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2018-09-28Update Arm copyright notices in new math filesWilco Dijkstra26-47/+79
While working on the strstr patch I noticed several copyright headers of the new math functions are missing closing quotes after ``AS IS. I've added these. Also update spellings of Arm Ltd in a few places (but still use ARM LTD in upper case portion). Finally add SPDX identifiers to make everything consistent.
2018-09-18Fix the documentation comment of checkintSzabolcs Nagy2-2/+4
checkint in pow is not supposed to be used with 0, inf or nan inputs.

2018-08-16Improve sincosf commentsWilco Dijkstra4-21/+26
Improve comments in sincosf implementation to make the code easier to understand. Rename the constant pi64 to pi63 since it's actually PI * 2^-63. Add comments for fields of sincos_t structure. Add comments describing implementation details to reduce_fast.

2018-07-11Remove float compare option from sincosfSzabolcs Nagy1-10/+1
PREFER_FLOAT_COMPARISON setting was not correct as it could raise spurious exceptions. Fixing it is easy: just use ISLESS(x, y) instead of abstop12(x) < abstop12(y) with appropriate non-signaling definition for ISLESS. However it seems this setting is not very useful (there is only minor performance difference on various architectures), so remove this option for now.
2018-07-11Fix the documentation comments for log_inline in powSzabolcs Nagy1-3/+3
There was a typo and the arguments were not explained clearly.
2018-07-06Fix namespace issues in sinf, cosf and sincosfSzabolcs Nagy5-18/+19
Use const sincos_t for clarity instead of making the typedef const. Use __inv_pi4 and __sincosf_table to avoid namespace issues with static linking.
2018-07-06Fix large ulp error in pow without fma very near 1.0Szabolcs Nagy1-2/+4
The !HAVE_FAST_FMA code path split r = z/c - 1 into r = rhi + rlo such that when z = 1-tiny and c = 1 then rlo and rhi could have much larger magnitude than r which later caused large rounding errors. So do a nearest rounding instead of truncation at the split. In newlib with default settings this was observable on some arm targets that enable the new math code but has no fma.
2018-07-06Change the return type of converttoint and document the semanticsSzabolcs Nagy1-1/+9
The roundtoint and converttoint internal functions are only called with small values, so 32 bit result is enough for converttoint and it is a signed int conversion so the natural return type is int32_t. The original idea was to help the compiler keeping the result in uint64_t, then it's clear that no sign extension is needed and there is no accidental undefined or implementation defined signed int arithmetics. But it turns out gcc does a good job with inlining so changing the type has no overhead and the semantics of the conversion is less surprising this way. Since we want to allow the asuint64 (x + 0x1.8p52) style conversion, the top bits were never usable and the existing code ensures that only the bottom 32 bits of the conversion result are used. In newlib with default settings only aarch64 is affected and there is no significant code generation change with gcc after the patch.
2018-07-06Remove unused TOINT_RINT and TOINT_SHIFT macrosSzabolcs Nagy2-10/+1
Only have separate code paths for TOINT_INTRINSICS and !TOINT_INTRINSICS.
2018-07-06Move __HAVE_FAST_FMA to math_config.hSzabolcs Nagy6-12/+21
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.
2018-07-06Fix code style and comments of new math codeSzabolcs Nagy8-74/+134
Synchronize code style and comments with Arm Optimized Routines, there are no code changes in this patch. This ensures different projects using the same code have consistent code style so bug fix patches can be applied more easily.
2018-06-27New pow implementationSzabolcs Nagy6-4/+603
The new implementation is provided under !__OBSOLETE_MATH, it uses ISO C99 code. With default settings the worst case error in nearest rounding mode is 0.54 ULP with inlined fma and fma contraction. It uses a 4 KB lookup table in addition to the table in exp_data.c, on aarch64 .text+.rodata size of libm.a is increased by 2295 bytes. Improvements on Cortex-A72: latency: 3.3x thruput: 4.9x
2018-06-27New log2 implementationSzabolcs Nagy6-4/+399
The new implementation is provided under !__OBSOLETE_MATH, it uses ISO C99 code. With default settings the worst case error in nearest rounding mode is 0.547 ULP with inlined fma and fma contraction. It uses a 1 KB lookup table, on aarch64 .text+.rodata size of libm.a is increased by 1584 bytes. Note that the math.h header defines log2(x) to be log(x)/Ln2, this is not changed, so the new code is only used if that macro is suppressed. Improvements on Cortex-A72: latency: 2.0x thruput: 2.2x
2018-06-27New log implementationSzabolcs Nagy6-4/+717
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
2018-06-27New exp and exp2 implementationsSzabolcs Nagy8-5/+1132
The new implementations are provided under !__OBSOLETE_MATH, they use ISO C99 code. There are several settings, with the default one the worst case error in nearest rounding mode is 0.509 ULP for exp and 0.507 ULP for exp2 when a multiply and add is contracted into an fma. They use a shared 2 KB lookup table, on aarch64 .text+.rodata size of libm.a is increased by 1868 bytes. The w_*.c wrappers are disabled for the new code as it takes care of error handling inline. The old exp2(x) code used to be just pow(2,x) so the speedup there is more significant. The file name has no special prefix to avoid any name collision with existing files. Improvements on Cortex-A72: exp latency: 3.2x exp thruput: 4.1x exp2 latency: 7.8x exp2 thruput: 18.8x
2018-06-27Use uint32_t sign argument to math error functionsSzabolcs Nagy3-13/+13
This change is equivalent to the commit https://github.com/ARM-software/optimized-routines/commit/c65db17340782d647c49e17cbba244862dc38402 and only affects code that is from the Arm optimized-routines project. It does not affect the observable behaviour, but the code generation can be different on 64bit targets. The intention is to make the portable semantics of the code obvious by using a fixed size type.
2018-06-21Improve performance of sinf/cosf/sincosfWilco Dijkstra8-6/+660
Here is the correct patch with both filenames and int cast fixed: This patch is a complete rewrite of sinf, cosf and sincosf. The new version is significantly faster, as well as simple and accurate. The worst-case ULP is 0.56072, maximum relative error is 0.5303p-23 over all 4 billion inputs. In non-nearest rounding modes the error is 1ULP. The algorithm uses 3 main cases: small inputs which don't need argument reduction, small inputs which need a simple range reduction and large inputs requiring complex range reduction. The code uses approximate integer comparisons to quickly decide between these cases - on some targets this may be slow, so this can be configured to use floating point comparisons. The small range reducer uses a single reduction step to handle values up to 120.0. It is fastest on targets which support inlined round instructions. The large range reducer uses integer arithmetic for simplicity. It does a 32x96 bit multiply to compute a 64-bit modulo result. This is more than accurate enough to handle the worst-case cancellation for values close to an integer multiple of PI/4. It could be further optimized, however it is already much faster than necessary.

2017-10-20fix internal __ieee754_expf and __ieee754_logf callsSzabolcs Nagy1-0/+11
The recently added new math code inlines error handling instead of using error handling wrappers around __ieee754* internal symbols, and thus the __ieee754* symbols are no longer provided. However __ieee754_expf and __ieee754_logf are used in the implementation of a number of other math functions. These symbols are safe to redirect to the external expf and logf symbols, because those names are always reserved when single precision math functions are reserved and the additional error handling code is either not reached or there will be an error in the final result that will override an internal spurious errno setting. For consistency all of __ieee754_expf, __ieee754_logf and __ieee754_powf are redirected using a macro.
2017-10-13New expf, exp2f, logf, log2f and powf implementationsSzabolcs Nagy13-84/+1235
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. libm.a size changes: arm: -1692 arm/thumb/v7-a/nofp: -878 arm/thumb/v7-a+fp/hard: -864 arm/thumb/v7-a+fp/softfp: -908 aarch64: -1476
2017-04-18newlib: remove __infinity{f,ld} constantsCorinna Vinschen3-31/+4
previous commit 4c90db7bc89e7fa1077025fefdd58269dc71a6ac introduced a compile time error because libm/common/s_infconst.c used the remove __fmath, __dmath, and __ldmath union types. Since this is very old, and unused for a very long time, just drop the file and thus the __infinity constants entirely. Exception: Cygwin exports __infinity from the beginning. There's a very, VERY low probability that any existing executable or lib still uses this constant, but we just keep it in for backward compat, nevertheless.
