2022-01-01Update copyright dates with scripts/update-copyrightsPaul Eggert
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
2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar
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>

2019-12-11S390: Use libc_fe* macros in fe* functions.Stefan Liebler
This patch updates the s390 specific functions fegetround, fesetround, feholdexcept, fesetenv, feupdateenv, fegetexceptflag, fetestexcept, fesetexceptflag, fetestexceptflag. Now those functions are using the libc_fe* macros if possible. Furthermore fegetexceptflag is now returning the exception from dxc field shifted to the usual exception-flags. Thus a special fetestexceptflag implementation is not needed anymore.

Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !

2016-08-31S390: Do not set FE_INEXACT with feraiseexcept (FE_OWERFLOW|FE_UNDERFLOW).Stefan Liebler
On s390 feraiseexcept (FE_OVERFLOW|FE_UNDERFLOW) sets FE_INEXACT, too. This patch uses z196 zarch load rounded instruction which can suppress FE_INEXACT exception if gcc has z196 support in used configuration. Otherwise FE_INEXACT flag is set as before. The gcc support is tested in a new configure-check. A comment in fsetexcptflg.c is corrected as new exceptions are not executed with the next floating-point instruction if fpc is set with _FPU_SETCW macro. It seems the comment was copied e.g. from sysdeps/x86_64/fpu/fsetexcptflg.c file. ChangeLog: * config.h.in (HAVE_S390_MIN_Z196_ZARCH_ASM_SUPPORT): New undefine. * sysdeps/s390/configure.ac: Add test for z196 zarch support. * sysdeps/s390/configure: Regenerated. * sysdeps/s390/fpu/fraiseexcpt.c (__feraiseexcept): Use ledbra instruction for raising over-/underflow if z196 zarch is supported by default. * sysdeps/s390/fpu/fsetexcptflg.c (fesetexceptflag): Correct comment.

2015-08-26S390: Fix handling of DXC-byte in FPC-register.Stefan Liebler
On s390, the DXC(data-exception-code)-byte in FPC(floating-point-control)- register contains a code of the last occured exception. If bits 6 and 7 of DXC-byte are zero, the bits 0-5 correspond to the ieee-exception flag bits. The current implementation always uses these bits as ieee-exception flag bits. fetestexcept() reports any exception after the first usage of a vector-instruction in a process, because it raises an "vector instruction exception" with DXC-code 0xFE. This patch fixes the handling of the DXC-byte. The DXC-Byte is only handled if bits 6 and 7 are zero. The #define _FPU_RESERVED is extended by the DXC-Byte. Otherwise the tests math/test-fpucw-static and math/test-fpucw-ieee-static fails, because DXC-Byte contains the vector instruction exception when reaching main(). This exception was triggered by strrchr() call in __init_misc(). __init_misc() is called after __setfpucw () in __libc_init_first(). The field __ieee_instruction_pointer in struct fenv_t is renamed to __unused because it is a relict from commit "Remove PTRACE_PEEKUSER" (87b9b50f0d4b92248905e95a06a13c513dc45e59) and isnĀ“t used anymore. ChangeLog: [BZ #18610] * sysdeps/s390/fpu/bits/fenv.h (fenv_t): Rename __ieee_instruction_pointer to __unused. * sysdeps/s390/fpu/fesetenv.c (__fesetenv): Remove usage of __ieee_instruction_pointer. * sysdeps/s390/fpu/fclrexcpt.c (feclearexcept): Fix dxc-field handling. * sysdeps/s390/fpu/fgetexcptflg.c (fegetexceptflag): Likewise. * sysdeps/s390/fpu/fsetexcptflg.c (fesetexceptflag): Likewise. * sysdeps/s390/fpu/ftestexcept.c (fetestexcept): Likewise. * sysdeps/s390/fpu/fpu_control.h (_FPU_RESERVED): Mark dxc-field as reserved.
