* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-033-4/+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>

* Add libm_alias_finite for _finite symbolsWilco Dijkstra2020-01-031-1/+2
| | | | | | | | | | | | | | | | | | | This patch adds a new macro, libm_alias_finite, to define all _finite symbol. It sets all _finite symbol as compat symbol based on its first version (obtained from the definition at built generated first-versions.h). The <fn>f128_finite symbols were introduced in GLIBC 2.26 and so need special treatment in code that is shared between long double and float128. It is done by adding a list, similar to internal symbol redifinition, on sysdeps/ieee754/float128/float128_private.h. Alpha also needs some tricky changes to ensure we still emit 2 compat symbols for sqrt(f). Passes buildmanyglibc.

* Do not define various fenv.h macros for MIPS soft-float (bug 23479).Joseph Myers2018-08-021-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS soft-float glibc does not support floating-point exceptions and rounding modes, and uses a different ABI from hard-float so a soft-float compilation cannot use a glibc that does support floating-point exceptions and rounding modes. Thus, bits/fenv.h should not, when compiling for soft-float, define macros for the unsupported features. This patch changes it accordingly to define those macros only for hard-float. None of the exception macros are defined for soft-float, with FE_ALL_EXCEPT defined to 0 in that case, and only FE_TONEAREST is defined of the rounding-mode macros, and FE_NOMASK_ENV is not defined; this is consistent with how architectures lacking exception and rounding mode support generally define things in this header. As well as making the header more correct for this case, this also means the generic math_private.h optimizations for this case automatically apply (inlining libm-internal fenv.h function calls that are trivial when exceptions and rounding modes are not supported). The mips64 sfp-machine.h then needs similar changes to disable more of the exception and rounding mode handling for soft-float. (The mips32 sfp-machine.h is already used only for soft-float, has no integration with hardware exceptions or rounding modes and so needs no changes.) Existing binaries might use the old FE_NOMASK_ENV value as an argument to fesetenv / feupdateenv and expect an error for it (given that it was defined in a header that also defined FE_ALL_EXCEPT to a nonzero value). To preserve that error, wrappers for the fallback fesetenv and feupdateenv are created in sysdeps/mips/nofpu/. Tested for mips64 (hard-float and soft-float, all three ABIs).

* mips64: fix clobbering s0 in setjmp() [BZ #22624]Sergei Trofimovich2017-12-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When configured as --enable-stack-protector=all glibc inserts stack checking canary into every function including __sigsetjmp_aux(). Stack checking code ends up using s0 register to temporary hold address of global canary value. Unfortunately __sigsetjmp_aux assumes no caller' caller-save registers should be clobbered as it stores them as-is. The fix is to disable stack protection of __sigsetjmp_aux. Tested on the following test: #include <setjmp.h> #include <stdio.h> int main() { jmp_buf jb; volatile register long s0 asm ("$s0"); s0 = 1234; if (setjmp(jb) == 0) longjmp(jb, 1); printf ("$s0 = %lu\n", s0); } Without the fix: $ qemu-mipsn32 -L . ./mips-longjmp-bug $s0 = 1082346228 With the fix: $ qemu-mipsn32 -L . ./mips-longjmp-bug $s0 = 1234 [BZ #22624] * sysdeps/mips/mips64/setjmp_aux.c (__sigsetjmp_aux): Use inhibit_stack_protector.
* Add sysdeps/ieee754/soft-fp.Joseph Myers2017-12-124-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default sysdeps/ieee754 fma implementations rely on exceptions and rounding modes to achieve correct results through internal use of round-to-odd. Thus, glibc configurations without support for exceptions and rounding modes instead need to use implementations of fma based on soft-fp. At present, this is achieved via having implementation files in soft-fp/ that are #included by sysdeps files for each glibc configuration that needs them. In general this means such a configuration has its own s_fma.c and s_fmaf.c. TS 18661-1 adds functions that do an operation (+ - * / sqrt fma) on arguments wider than the return type, with a single rounding of the infinite-precision result to that return type. These are also naturally implemented using round-to-odd on platforms with hardware support for rounding modes and exceptions but lacking hardware support for these narrowing operations themselves. (Platforms that have direct hardware support for such narrowing operations include at least ia64, and Power ISA 2.07 or later, which I think means POWER8 or later.) So adding the remaining TS 18661-1 functions would mean at least six narrowing function implementations (fadd fsub fmul fdiv ffma fsqrt), with aliases for other types and further implementations in some configurations, that need to be overridden for configurations lacking hardware exceptions and rounding modes. Requiring all such configurations (currently seven of them) to have their own source files for all those functions seems undesirable. Thus, this patch adds a directory sysdeps/ieee754/soft-fp to contain libm function implementations based on soft-fp. This directory is then used via Implies from all the configurations that need it, so no more files need adding to every such configuration when adding more functions with soft-fp implementations. A configuration can still selectively #include a particular file from this directory if desired; thus, the MIPS #include of the fmal implementation is retained, since that's appropriate even for hard float (because long double is always implementated in software for MIPS64, so the soft-fp implementation of fmal is better than the ldbl-128 one). This also provides additional motivation for my recent patch removing --with-fp / --without-fp: previously there was no need for correct use of --without-fp for no-FPU ARM or SH3, and now we have autodetection nofpu/ sysdeps directories can be used by this patch for those configurations without imposing any new requirements on how glibc is configured. (The mips64/*/fpu/s_fma.c files added by this patch are needed to keep the dbl-64 version of fma for double, rather than the ldbl-128 one, used in that case.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

* Regenerate MIPS catan, catanh long double ulps.Joseph Myers2017-03-091-16/+16
| | | | | | | | | | | | This patch regenerates MIPS catan and catanh ulps for long double with fixed expected results for the tests of those functions. ulps for other types (which may see variation depending on whether glibc is built for a processor with fused multiply-add support) are deliberately not reduced. ulps are not regenerated for powerpc-nofpu as such regeneration does not result in any changes for long double. * sysdeps/mips/mips64/libm-test-ulps: Update catan and catanh ulps for long double with corrected test expectations.

* Make MIPS soft-fp preserve NaN payloads for NAN2008.Joseph Myers2017-01-041-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | This corresponds to a patch applied to libgcc. In glibc it doesn't actually affect much (only fma, I think). The MIPS sfp-machine.h files have an _FP_CHOOSENAN implementation which emulates hardware semantics of not preserving signaling NaN payloads for an operation with two NaN arguments (although that doesn't suffice to avoid sNaN payload preservation in any case with just one NaN argument). However, those are only hardware semantics in the legacy NaN case; in the NAN2008 case, the architecture documentation says hardware preserves payloads in such cases. Furthermore, this implementation assumes legacy NaN semantics, so in the NAN2008 case the implementation actually has the effect of preserving sNaN payloads but not preserving qNaN payloads, when both should be preserved. This patch fixes the code just to copy from the first argument. Tested for mips64 soft-float. * sysdeps/mips/mips32/sfp-machine.h (_FP_CHOOSENAN): Always preserve NaN payload if [__mips_nan2008]. * sysdeps/mips/mips64/sfp-machine.h (_FP_CHOOSENAN): Likewise.

* MIPS: Add `.insn' to ensure a text label is defined as code not dataMaciej W. Rozycki2016-11-182-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid a build error with microMIPS compilation and recent versions of GAS which complain if a branch targets a label which is marked as data rather than microMIPS code: ../sysdeps/mips/mips32/crti.S: Assembler messages: ../sysdeps/mips/mips32/crti.S:72: Error: branch to a symbol in another ISA mode make[2]: *** [.../csu/crti.o] Error 1 as commit 9d862524f6ae ("MIPS: Verify the ISA mode and alignment of branch and jump targets") closed a hole in branch processing, making relocation calculation respect the ISA mode of the symbol referred. This allowed diagnosing the situation where an attempt is made to pass control from code assembled for one ISA mode to code assembled for a different ISA mode and either relaxing the branch to a cross-mode jump or if that is not possible, then reporting this as an error rather than letting such code build and then fail unpredictably at the run time. This however requires the correct annotation of branch targets as code, because the ISA mode is not relevant for data symbols and is therefore not recorded for them. The `.insn' pseudo-op is used for this purpose and has been supported by GAS since: Wed Feb 12 14:36:29 1997 Ian Lance Taylor <ian@cygnus.com> * config/tc-mips.c (mips_pseudo_table): Add "insn". (s_insn): New static function. * doc/c-mips.texi: Document .insn. so there has been no reason to avoid it where required. More recently this pseudo-op has been documented, by the microMIPS architecture specification[1][2], as required for the correct interpretation of any code label which is not followed by an actual instruction in an assembly source. Use it in our crti.S files then, to mark that the trailing label there with no instructions following is indeed not a code bug and the branch is legitimate.

* Do not hardcode platform names in manual/libm-err-tab.pl (bug 14139).Joseph Myers2016-11-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | manual/libm-err-tab.pl hardcodes a list of names for particular platforms (mapping from sysdeps directory name to friendly name for the manual). This goes against the principle of keeping information about individual platforms in their corresponding sysdeps directory, and the list is also very out-of-date regarding supported platforms and their corresponding sysdeps directories. This patch fixes this by adding a libm-test-ulps-name file alongside each libm-test-ulps file. The script then gets the friendly name from that file, which is required to exist, so it no longer needs to allow for the mapping being missing. Tested for x86_64.

* Fix ulps regeneration for *-finite tests.Joseph Myers2016-01-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On running tests after from-scratch ulps regeneration, I found that some libm tests failed with ulps in excess of those recorded in the from-scratch regeneration, which should never happen unless those ulps exceed the limit on ulps that can go in libm-test-ulps files.

Those tests share ulps with the default function variants. make regen-ulps runs the default tests before the finite-math-only tests, concatenating the resulting ulps before feeding them to gen-libm-test.pl to generate a new libm-test-ulps file. But gen-libm-test.pl always takes the last ulps value given for any (function, type) pair. So, if the largest ulps for a function come from non-finite inputs, a from-scratch regeneration loses those ulps. This patch fixes gen-libm-test.pl, in the case where there are multiple ulps values for a (function, type) pair - which can only happen as part of a regeneration - to take the largest ulps value rather than the last one.

| | | | | | | | | | | | This patch enables use of sysdeps/ieee754/dbl-64/wordsize-64 for MIPS64 (both n64 and n32), removing a #error in one case now that case has been tested and found to work.

| | | | | | | | | | | | | | | | | | | | | This patch adds more libm test inputs found through random test generation to increase previously known ulps. This particular test generation was run for mips64, so most of the increased ulps are for ldbl-128 (float and double having been fairly well covered by such testing for x86_64), but there's the odd ulps increase for other formats. Tested for x86_64, x86 and mips64. * math/auto-libm-test-in: Add more tests of acos, acosh, asin, asinh, atan, atan2, atanh, cabs, carg, cos, csqrt, erfc, exp, exp10, exp2, log, log1p, log2, pow, sin, sincos, sinh, tan and tanh. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/mips/mips32/libm-test-ulps: Likewise. * sysdeps/mips/mips64/libm-test-ulps: Likewise. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.

| | | | | | | | | | | | | | | | | | | | | | | As noted in <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, soft-fp sysdeps subdirectories (and more generally, subdirectories where sysdeps/foo/Implies contains foo/bar) are unnecessary and should be eliminated.

* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-17838/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment.
