| | | | | | | | | | | | | | | | | | | | | | | 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>

* Use libm_alias_double for sparc.Joseph Myers2017-11-291-1/+2

Tested with build-many-glibcs.py for all its sparc configurations that installed stripped shared libraries are unchanged by the patch. * sysdeps/sparc/sparc32/fpu/s_copysign.S: Include <libm-alias-double.h>.

* SPARC: fix nearbyint on sNaN inputAurelien Jarno2016-07-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | nearbyint and nearbyintf should not trigger inexact exceptions, but should still trigger an invalid exception for a sNaN input. The SPARC specific implementations of these functions save the FSR at the beginning of the function and restore it at the end to not trigger an inexact exception. This however doesn't work for an sNaN input which need to trigger an invalid exception. Fix that by adding a fcmp instruction using the input value before saving FSR, so that an invalid exception is triggered for a sNaN input. This fixes the math/test-nearbyint-except test on SPARC. Changelog: * sparc/sparc32/sparcv9/fpu/s_nearbyint.S (__nearbyint): Trigger an invalid exception for a sNaN input. * sparc/sparc32/sparcv9/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise * sparc/sparc64/fpu/s_nearbyint.S (__nearbyint): Likewise. * sparc/sparc64/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise.
