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.

2018-09-04Move fenv.h soft-float inlines from fenv_private.h to include/fenv.h.Joseph Myers1-1/+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 ....

2018-09-03Do not include fenv_private.h in math_private.h.Joseph Myers1-0/+1
Continuing the clean-up related to the catch-all math_private.h header, this patch stops math_private.h from including fenv_private.h. 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).

2014-12-31Clean up powerpc fegetround / __fegetround inlines.Joseph Myers1-1/+1
The natural fix for some linknamespace test failures, where C90 libm functions call C99 <fenv.h> functions, is to make fe* into weak aliases for __fe* and call __fe* from within libm as needed. To do this, the __fe* names need to be available for that purpose - that is, they must not be used for something other than aliases of fe*. On powerpc, however, __fegetround is an inline function in fenv_libc.h, with no corresponding fegetround inline function; fegetround has an equivalent macro expansion in bits/fenvinline.h, but that is disabled if __NO_MATH_INLINES (which is defined for building libm). I see no need for that disabling; it's not even clear that __NO_MATH_INLINES should affect <fenv.h>, and the results of fegetround are completely defined so there is no semantic effect of that disabling at all outside glibc. The x86 inline feraiseexcept is conditioned on __USE_EXTERN_INLINES not __NO_MATH_INLINES (but that's an inline function rather than a macro). This patch removes the __NO_MATH_INLINES conditional on that fegetround macro, so resulting in it being expanded inline inside glibc. In turn, this means that direct calls to __fegetround from C99 functions in ldbl-128ibm can be changed to calls to fegetround, so that nofpu fenv_libc.h files don't need to define __fegetround at all and, by changing ldbl-128ibm files to use <fenv.h> not <fenv_libc.h>, non-e500 nofpu no longer needs an fenv_libc.h file. The other macros in fenvinline.h are left conditional on __NO_MATH_INLINES, although since the only case where this should make a difference is one involving undefined behavior (if the argument to the function is not a valid exception macro). The out-of-line definition for fegetround uses __fegetround (the inline function removed by this patch). So this continues to work, the fenvinline.h header is made to define __fegetround, and then to define fegetround to call __fegetround. Tested for powerpc32 (hard float) that installed stripped shared libraries are unchanged by this patch; also tested that powerpc-nofpu build still works. (This patch does not itself fix any bugs; it simply cleans things up in preparation for separate bug fixes.) * sysdeps/powerpc/bits/fenvinline.h (fegetround): Rename macro to __fegetround and redefine to call __fegetround.
