As pointed out in https://sourceware.org/ml/libc-alpha/2017-03/msg00487.html,
some complications were created in the macroized version of math_private.h
because I was replicating the peculiarities of the existing header.
In this new patch series, I clean those peculiarities, thus making the
macroized version of math_private.h more straightforward.
Gabriel F. T. Gomes (3):
Remove unneeded declarations from math_private.h
Change return type in the declaration of __ieee754_rem_pio2l
Macroize function declarations in math_private.h

OK apart from the removal of the inline definition of __copysignl. That inline definition is still relevant in the absence of changing all calls to __copysign* to call copysign* directly so the compiler can inline them (and if changed to call copysign*, which I think would make sense, it would be desirable to run build-many-glibcs.py tests to make sure this doesn't introduce linknamespace issues). -- Joseph S.

* [PATCH v3 3/3] Macroize function declarations in math_private.h 2017-03-28 20:45 ` [PATCH v2 3/3] Macroize function declarations in math_private.h Gabriel F. T. Gomes @ 2017-03-30 12:03 ` Gabriel F. T. Gomes 2017-04-10 18:04 ` Gabriel F. T. Gomes 2017-04-19 21:52 ` Joseph Myers 0 siblings, 2 replies; 13+ messages in thread From: Gabriel F. T. Gomes @ 2017-03-30 12:03 UTC (permalink / raw) To: libc-alpha Changes since v2: - Adjust the removal of __copysignl. Changes since v1: - Rename math_private_common.h to math_private_calls.h - Do not depend on _Mint_ for __ieee754_rem_pio2*, since all of them return int32_t (patch 2/3). - Remove declarations of many functions since they are not required (patch 1/3). -- 8< -- 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. 2017-03-17 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com> * 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. --- sysdeps/generic/math_private.h | 192 ++++------------------------------- sysdeps/generic/math_private_calls.h | 124 ++++++++++++++++++++++ 2 files changed, 146 insertions(+), 170 deletions(-) create mode 100644 sysdeps/generic/math_private_calls.h diff --git a/sysdeps/generic/math_private.h b/sysdeps/generic/math_private.h index 09117b7..aba1cb9 100644 --- a/sysdeps/generic/math_private.h +++ b/sysdeps/generic/math_private.h @@ -184,146 +184,33 @@ do { \ /* Get long double macros from a separate header. */ #include <math_ldbl.h> -/* ieee style elementary functions */ -extern double __ieee754_sqrt (double);
