* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011-1/+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 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Move fenv.h soft-float inlines from fenv_private.h to include/fenv.h.Joseph Myers2018-09-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <fenv_private.h> has inline versions of various <fenv.h> functions, and their __fe* variants, for systems (generally soft-float) without support for floating-point exceptions, rounding modes or both. Having these inlines in a separate header introduces a risk of a source file including <fenv.h> and compiling OK on x86_64, but failing to compile (because the feraiseexcept inline is actually a macro that discards its argument, to avoid the need for #ifdef FE_INVALID conditionals), or not being properly optimized, on systems without the exceptions and rounding modes support (when these inlines were in math_private.h, we had a few cases where this broke the build because there was no obvious reason for a file to need math_private.h and it didn't need that header on x86_64). By moving those inlines to include/fenv.h, this risk can be avoided, and fenv_private.h becomes more clearly defined as specifically the header for the internal libc_fe* and SET_RESTORE_ROUND* interfaces. This patch makes that move, removing fenv_private.h includes that are no longer needed (or replacing them by fenv.h includes in a few cases that didn't already have such an include). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/fenv_private.h [FE_ALL_EXCEPT == 0]: Move this code ....

Instead, fenv_private.h is included directly from those users of math_private.h that also used interfaces from fenv_private.h. No attempt is made to remove unused includes of math_private.h, but that is a natural followup. (However, since math_private.h sometimes defines optimized versions of math.h interfaces or __* variants thereof, as well as defining its own interfaces, I think it might make sense to get all those optimized versions included from include/math.h, not requiring a separate header at all, before eliminating unused math_private.h includes - that avoids a file quietly becoming less-optimized if someone adds a call to one of those interfaces without restoring a math_private.h include to that file.) There is still a pitfall that if code uses plain fe* and __fe* interfaces, but only includes fenv.h and not fenv_private.h or (before this patch) math_private.h, it will compile on platforms with exceptions and rounding modes but not get the optimized versions (and possibly not compile) on platforms without exception and rounding mode support, so making it easy to break the build for such platforms accidentally. I think it would be most natural to move the inlines / macros for fe* and __fe* in the case of no exceptions and rounding modes into include/fenv.h, so that all code including fenv.h with _ISOMAC not defined automatically gets them. Then fenv_private.h would be purely the header for the libc_fe*, SET_RESTORE_ROUND etc. internal interfaces and the risk of breaking the build on other platforms than the one you tested on because of a missing fenv_private.h include would be much reduced (and there would be some unused fenv_private.h includes to remove along with unused math_private.h includes).

This macro handles defining aliases for double, and for long double in the NO_LONG_DOUBLE case. It also handles defining compat symbols for long double = double for architectures that changed their long double format. By so doing, it eliminates the need for the M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single declare_mgen_alias call in each template now suffices to define all required compat symbols. When used for more double functions (not based on type-generic templates), I expect it will eliminate the need for most ldbl-opt wrappers for such functions. A few special cases are needed. __clog10l is a public symbol (for historical reasons) so needs to be given appropriate compat versions for architectures that changed their long double format, but is not defined as an alias using the normal macros since __clog10* are *not* public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and log1p, the changes adding errno setting support for those functions left compat symbols pointing directly to the non-errno-setting implementations. There is no requirement for the compat symbols not to set errno; that just made for the simplest patches at that time. Now, with these common macros, it's natural to redirect the compat symbols to the errno-setting wrappers, which I intend to do in a separate patch. Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt platforms the stripped libm.so binaries are changed (disassembly unchanged) because the details of how the clog10l compat symbol is created mean it ceases to be weak as it was before; for other platforms, stripped libm.so binaries are unchanged. 2017-09-13 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/libm-alias-double.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Likewise. * sysdeps/generic/math-type-macros-double.h: Include <libm-alias-double.h>.

* Clean up some complex functions raising FE_INVALID.Joseph Myers2016-10-141-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the complex arithmetic functions have the following pattern: in some piece of code, one part of the input (real or imaginary, depending on the function) is either infinite or NaN. Part of the result is to be set to NaN in either case, and FE_INVALID raised only if the relevant part of the input was infinite. In such a case, there is no actual need for the conditional on the type of the input, since subtracting the relevant part of the input from itself will produce a NaN, with FE_INVALID only if the relevant part of the input was infinite. This simplifies the code, and as a quality-of-implementation matter also improves things by propagating NaN payloads. (Right now these functions always raise FE_INVALID for signaling NaN arguments because of the call to fpclassify - at least unless glibc is built with -Os - but if fpclassify moves to using integer arithmetic in future, doing arithmetic on the NaN argument also ensures an exception for sNaNs.) Tested for x86_64 and x86. * math/s_ccosh_template.c (M_DECL_FUNC (__ccosh)): Instead of raising FE_INVALID with feraisexcept in case where part of argument is infinite, subtract that part of argument from itself. * math/s_cexp_template.c (M_DECL_FUNC (__cexp)): Likewise. * math/s_csin_template.c (M_DECL_FUNC (__csin)): Likewise. * math/s_csinh_template.c (M_DECL_FUNC (__csinh)): Likewise.
