* 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 Poyarekar2021-09-031-4/+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>

* Do not use packed structures in soft-fp.Joseph Myers2018-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building for soft-float ColdFire produces an error in soft-fp: In file included from ../sysdeps/ieee754/soft-fp/s_fmaf.c:42: ../soft-fp/single.h:85:3: error: 'packed' attribute ignored for field of type 'struct <anonymous>' [-Werror=attributes] } bits __attribute__ ((packed)); ^ While this error only appears in that particular case, this attribute is in fact never useful, on any architecture. If you have struct __attribute__ ((packed)) { ... } bits; or struct { ... } __attribute__ ((packed)) bits; then the attribute affects the layout of the structure type. But with the form used in this code struct { ... } bits __attribute__ ((packed)); the field bits is being declared packed, but the layout of its type has already been determined at that point. If on any platform the layout of the sequence of bit-fields were wrong without the use of a packed attribute, the attribute would need to be used via a definition of _FP_STRUCT_LAYOUT, not in its present position. So this patch removes the useless attribute to fix the build for ColdFire soft-float. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * soft-fp/double.h (union _FP_UNION_D): Do not use attribute packed on bits. * soft-fp/extended.h (union _FP_UNION_E): Likewise. * soft-fp/half.h (union _FP_UNION_H): Likewise. * soft-fp/quad.h (union _FP_UNION_Q): Likewise. * soft-fp/single.h (union _FP_UNION_S): Likewise.

* soft-fp: Use multiple-include guards.Joseph Myers2015-03-101-0/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch makes soft-fp headers consistently use multiple-include guards, something previously done mainly only in the Linux kernel version. The guard macros aren't the same as those used in the Linux kernel, but there seems to be enough variation in such guards in Linux kernel code that hopefully this version will be acceptable there.

* soft-fp: Add _FP_TO_INT_ROUND.Joseph Myers2014-11-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the series of patches adding soft-fp features from the kernel version of soft-fp to glibc so that glibc's version is able to replace the old fork of soft-fp in the kernel, this patch adds the last major such feature: _FP_TO_INT_ROUND, converting a floating-point number to an integer with rounding according to the current rounding direction (as opposed to truncating towards zero, which _FP_TO_INT does). The general structure of the implementation follows that of _FP_TO_INT, but of course is more complicated. As with glibc's _FP_TO_INT it works with raw input (the kernel versions of these macros predate the conversion of _FP_TO_INT and many other macros to raw or semi-raw input). I have not tried to work out what bugs there might be in the kernel version that this might fix; it's a from-scratch implementation based on _FP_TO_INT. Tested for powerpc (soft-float) that there is no change to the installed shared libraries; also tested with the libm tests with lrint / lrintf / llrint / llrintf made to use _FP_TO_INT_ROUND, to provide some test of the functionality. As we don't have benchmarks for those functions, I haven't actually included the soft-fp versions of them, although I expect them to be faster than the existing code (given that the existing code involves adding and subtracting numbers such as 0x1p52 to achieve the desired rounding, which is not particularly efficient when the underlying floating point is software floating point). 2014-11-04 Joseph Myers <joseph@codesourcery.com> * soft-fp/op-common.h (_FP_TO_INT_ROUND): New macro. * soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_TO_INT_ROUND_D): New macro.

(I'm not aware of any bugs caused by the lack of parentheses, but this is generally good practice. The patch is not exhaustive regarding internal macros where the arguments always come directly from the mantissa of a floating-point number, although probably those should be cleaned up in this regard as well.)

* soft-fp: Refactor exception handling for comparisons.Joseph Myers2014-10-091-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.
