* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* Use copysign functions not __copysign functions in glibc libm.Joseph Myers2018-09-271-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __copysign functions to call the corresponding copysign names instead, with asm redirection to __copysign when the calls are not inlined (all cases are inlined except for IBM long double for powerpc soft-float / e500v1). This eliminates the need for an inline function defining __copysign in terms of __builtin_copysign. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (MATH_REDIRECT_BINARY_ARGS): New macro.

* float128: Add private _Float128 declarations for libm.Paul E. Murphy2017-05-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the necessary bits to the private headers to support building the _Float128 libm functions.

(__isinff128): New inline implementation used when GCC < 7.0, since in this case __builtin_isinf_sign is broken. (fabsf128): New inline implementation that calls the builtin. (__EXPR_FLT128): New macro. (min_of_type): Optionally include _Float128 types too. * sysdeps/generic/math_private_calls.h (__kernel_sincos): Declare for _Float128. (__kernel_rem_pio2): Likewise. * sysdeps/ieee754/ldbl-opt/s_sin.c: (__DECL_SIMD_sincos_disablef128): New macro.
* Macroize function declarations in math_private.hGabriel F. T. Gomes2017-04-241-0/+124
This patch moves the declaration of many floating-point functions from math_private.h to math_private_calls.h and macroize the declaration to be dependent on floating-point type. For each of float, double, and long double, the new header file is included once. This reduces the amount of repetitive boilerplate that will be required when adding float128 versions of these functions. Tested for powerpc64le and s390x. * sysdeps/generic/math_private.h: Move the declaration of many functions to sysdeps/generic/math_private_calls.h. * sysdeps/generic/math_private_calls.h: New file with the declarations of the functions removed from math_private.h macroized by floating-point type.
