* Use floor functions not __floor functions in glibc libm.Joseph Myers2018-09-141-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the changes that were made to call sqrt functions directly in glibc, instead of __ieee754_sqrt variants, so that the compiler could inline them automatically without needing special inline definitions in lots of math_private.h headers, this patch makes libm code call floor functions directly instead of __floor variants, removing the inlines / macros for x86_64 (SSE4.1) and powerpc (POWER5). The redirection used to ensure that __ieee754_sqrt does still get called when the compiler doesn't inline a built-in function expansion is refactored so it can be applied to other functions; the refactoring is arranged so it's not limited to unary functions either (it would be reasonable to use this mechanism for copysign - removing the inline in math_private_calls.h but also eliminating unnecessary local PLT entry use in the cases (powerpc soft-float and e500v1, for IBM long double) where copysign calls don't get inlined). The point of this change is that more architectures can get floor calls inlined where they weren't previously (AArch64, for example), without needing special inline definitions in their math_private.h, and existing such definitions in math_private.h headers can be removed. Note that it's possible that in some cases an inline may be used where an IFUNC call was previously used - this is the case on x86_64, for example. I think the direct calls to floor are still appropriate; if there's any significant performance cost from inline SSE2 floor instead of an IFUNC call ending up with SSE4.1 floor, that indicates that either the function should be doing something else that's faster than using floor at all, or it should itself have IFUNC variants, or that the compiler choice of inlining for generic tuning should change to allow for the possibility that, by not inlining, an SSE4.1 IFUNC might be called at runtime - but not that glibc should avoid calling floor internally. (After all, all the same considerations would apply to any user program calling floor, where it might either be inlined or left as an out-of-line call allowing for a possible IFUNC.)

* Include most of elf/ modules-names in modules-names-tests.Joseph Myers2018-09-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm testing a patch to let the compiler expand calls to floor in libm as built-in function calls as much as possible, instead of calling __floor, so that no architecture-specific __floor inlines are needed, and then to arrange for non-inlined calls to end up calling __floor, as done with sqrt and __ieee754_sqrt. This shows up elf/tst-relsort1mod2.c calling floor, which must not be converted to a call to __floor. Now, while an IS_IN (libm) conditional could be added to the existing conditionals on such redirections in include/math.h, the _ISOMAC conditional ought to suffice (code in other glibc libraries shouldn't be calling floor or sqrt anyway, as they aren't provided in libc and the other libraries don't link with libm). But while tests are mostly now built with _ISOMAC defined, test modules in modules-names aren't unless also listed in modules-names-tests. As far as I can see, all the modules in modules-names in elf/ are in fact parts of tests and so listing them in modules-names-tests is appropriate, so they get built with something closer to the headers used for user code, except in a few cases that actually rely on something from internal headers. This patch duly sets modules-names-tests there accordingly (filtering out those tests that fail to build without internal headers). Tested for x86_64, and with build-many-glibcs.py. * elf/Makefile (modules-names-tests): New variable.
* Add new log2 implementationSzabolcs Nagy2018-09-121-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar algorithm is used as in log: log2(2^k x) = k + log2(c) + log2(x/c) where the last term is approximated by a polynomial of x/c - 1, the first order coefficient is about 1/ln2 in this case. There is separate code path when fma instruction is not available for computing x/c - 1 precisely, for which the table size is doubled. The worst case error is 0.547 ULP (0.55 without fma), the read only global data size is 1168 bytes (2192 without fma) on aarch64. The non-nearest rounding error is less than 1 ULP.

* Add new log implementationSzabolcs Nagy2018-09-121-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimized log using carefully generated lookup table with 1/c and log(c) values for small intervalls around 1. The log(c) is very near a double precision value, it has about 62 bits precision. The algorithm is log(2^k x) = k log(2) + log(c) + log(x/c), where the last term is approximated by a polynomial of x/c - 1. Near 1 a single polynomial of x - 1 is used. There is separate code path when fma instruction is not available for computing x/c - 1 precisely, in which case the table size is doubled. The code uses __builtin_fma under __FP_FAST_FMA to ensure it is inlined as an instruction. With the default configuration settings the worst case error is 0.519 ULP (and 0.520 without fma), the rodata size is 2192 bytes (4240 without fma). The non-nearest rounding error is less than 1 ULP.

* Remove x86_64 math_private.h asms.Joseph Myers2018-09-111-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The x86_64 math_private.h has asm versions of the macros to reinterpret between floating-point and integer types. This is the sort of thing we now strongly discourage; the expectation in such cases, where the generic C code gives the compiler all the information needed about the required semantics, is that you should get the compiler to do the right thing for the generic C code rather than writing an asm version. Trivial tests showed GCC generates the expected single instructions for reinterpretation from floating point to integer. In the other direction, it goes via memory when the asms don't; I asked about this in GCC bug 87236 and was advised this was deliberate for generic tuning because it was faster that way on some AMD processors (but -mtune=intel, and -Os with the latest GCC, avoid going via memory). The asms don't and can't know about those tuning details, so that's evidence that they are actually making the code worse. This patch removes the asms accordingly. Tested for x86_64. * sysdeps/x86_64/fpu/math_private.h (MOVD): Remove macro. (MOVQ): Likewise. (EXTRACT_WORDS64): Likewise. (INSERT_WORDS64): Likewise. (GET_FLOAT_WORD): Likewise.

* Add build-many-glibcs.py support for building more GCC libraries.Joseph Myers2018-09-111-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every so often we get libsanitizer or libgo builds breaking with new glibc because of some change in the glibc headers. glibc's build-many-glibcs.py deliberately disables libsanitizer and GCC languages other than C and C++ because the point is to test glibc and find glibc problems (including problems shown up by new compiler warnings in new GCC), not to test libsanitizer or libgo; if the compiler build fails because of libsanitizer or libgo failing to build, that could hide the existence of new problems in glibc. However, it seems reasonable to have a non-default mode where build-many-glibcs.py does build those additional pieces, which this patch adds. Note that I do not intend to run a build-many-glibcs.py bot with this new option. If people concerned with libsanitizer, libgo or other potentially affected GCC libraries wish to find out about such problems more quickly, they may wish to run such a bot or bots (and to monitor the results and fix issues found - obviously there will be some overlap with issues found by my bots not using that option). Note also that building a non-native Ada compiler requires a sufficiently recent native (or build-x-host, in general) Ada compiler to be used, possibly more or less the same version as being built. That needs to be in the PATH when build-many-glibcs.py --full-gcc is run; the script does not deal with setting up such a compiler (or any of the other host tools needed for building GCC and glibc, beyond the GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need to keep updating such a compiler manually when running a bot. Tested by running build-many-glibcs.py with the new option, with mainline GCC. There are build failures for various configurations, which may be of interest to Go / Ada people even if you're not interested in running such a bot: * mips64 / mips64el (all configuration): ICE building libstdc++, as seen without using the new option <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>. * aarch64_be: error building libgo (little-endian aarch64 works fine): version.go:67:13: error: expected ';' or ')' or newline 67 | BigEndian = | ^ version.go:67:3: error: reference to undefined name 'BigEndian' 67 | BigEndian = | ^ * arm (all configurations): error building libgo: /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap' 29 | if randomTrap == 0 { | ^ /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap' 38 | r1, _, errno := syscall.Syscall(randomTrap, | ^ What's happening there is, I think, that the arm*b*-*-* case in libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with the 'b' in the vendor part, and then something else is failing to handle GOARCH=armbe. Given that you can have configurations with multilibs of both endiannesses, endianness should always be detected by configure.ac, for all architectures, using a compile test of whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual matches to the host (= target at top-level) triplet. * armeb (all configurations): error building libada (for some reason the Arm libada configuration seems to do different things for EH for big-endian, which makes no sense to me and doesn't actually work): a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)" a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)" * hppa: error building libgo (same error as for aarch64_be). * ia64: ICE building libgo.

* Italian and Swiss locales: Use the correct separators (bug 10797).Rafal Luzynski2018-09-101-0/+10
| | | | | | | | | | | | | | | | | | | | CLDR and many other sources say that it_IT (Italian) should use a dot (".") as a thousands separator and a comma (",") as a decimal separator.

* Add build-many-glibcs.py --enable-obsolete-* configs.Joseph Myers2018-09-101-0/+6
| | | | | | | | | | | | | | | We've had issues before with build failures (with new GCC) in code only built with --enable-obsolete-rpc or --enable-obsolete-nsl not being reported for a while because build-many-glibcs.py does not test those configure options. This patch adds configurations (32-bit and 64-bit) using those options so that in future we can notice quickly if they start failing to build. Tested the new configurations do build with GCC 8. * scripts/build-many-glibcs.py (Context.add_all_configs): Add x86_64 and i686 configs using --enable-obsolete-rpc --enable-obsolete-nsl.

* Fix segfault in maybe_script_execute.Stefan Liebler2018-09-061-0/+5
| | | | | | | | | | | | | | | | | If glibc is built with gcc 8 and -march=z900, the testcase posix/tst-spawn4-compat crashes with a segfault. In function maybe_script_execute, the new_argv array is dynamically initialized on stack with (argc + 1) elements. The function wants to add _PATH_BSHELL as the first argument and writes out of bounds of new_argv. There is an off-by-one because maybe_script_execute fails to count the terminating NULL when sizing new_argv. ChangeLog: * sysdeps/unix/sysv/linux/spawni.c (maybe_script_execute): Increment size of new_argv by one.

* Remove alpha math_private.h.Joseph Myers2018-09-051-0/+2
| | | | | | | | | | | | | | | After some math_private.h cleanups (in particulat math-barriers.h being split out), the only thing left in the alpha math_private.h was macro definitions of __isnan and __isnanf, apparently (based on the comments) intended to avoid problems with inline definitions in other math_private.h files. Those inline definitions were removed in commit fe8c2b33aed067282ecac0cc3fdff1feef88548b, and the alpha math_private.h is no longer needed; this patch removes it. Tested with build-many-glibcs.py that installed stripped shared libraries for alpha are unchanged by the patch. * sysdeps/alpha/fpu/math_private.h: Remove.
* Move float128 inlines from sysdeps/generic/math_private.h to include/math.h.Joseph Myers2018-09-051-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Continuing the cleanup of math_private.h, with a view to it becoming the header for the APIs defined therein and not also a header with inline variants of math.h APIs, this patch moves inline definitions of __isinff128 and fabsf128 to include/math.h, so that any users of math.h in glibc automatically get the optimized functions rather than quietly missing them if they do not also include math_private.h. Tested for x86_64 and x86, and with build-many-glibcs.py with GCC 6. There are changes to installed stripped libc.so on configurations with distinct _Float128, because of __printf_fp_l code that now gets the __isinff128 inline where previously it called the out-of-line function because of the lack of a math_private.h call. It seems appropriate that this code does get the inline (as it would automatically with GCC 7 and later when the built-in function is used) rather than being the only place in glibc that does not. * sysdeps/generic/math_private.h [__HAVE_DISTINCT_FLOAT128 && !__GNUC_PREREQ (7, 0)] (__isinff128): Move this inline function .... [__HAVE_DISTINCT_FLOAT128] (fabsf128): And this one .... * include/math.h [!_ISOMAC]: To here....
* Move fenv.h soft-float inlines from fenv_private.h to include/fenv.h.Joseph Myers2018-09-041-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <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 ....

* Do not include fenv_private.h in math_private.h.Joseph Myers2018-09-031-0/+147

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).

* Make gen-libm-test.py treat plus_oflow and minus_oflow as non-finite.Joseph Myers2018-08-291-0/+5
| | | | | | | | | | | | | | | | | | | | | When converting gen-libm-test to Python, in one place I noted a bug in the old Perl version that I preserved in the Python version so that the generated output files were the same with both versions, as such comparisons help give confidence in the correctness of such a rewrite of a script. Now that the conversion has been done, this patch fixes that bug, by arranging for tests with plus_oflow or minus_oflow results (manually written tests in libm-test-*.inc that have overflowing results that thus depend on the rounding mode) to be properly treated as having non-finite results, and thus not run for the __FINITE_MATH_ONLY__ tests. (As the affected tests in fact did pass for __FINITE_MATH_ONLY__ testing, this is just a matter of logical correctness in the choice of which tests run for that case, rather than fixing any actual test failures.) Tested for x86_64. * math/gen-libm-test.py (gen_test_args_res): Also treat plus_oflow and minus_oflow as non-finite.
* Split fenv_private.h out of math_private.h more consistently.Joseph Myers2018-08-281-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some architectures, the parts of math_private.h relating to the floating-point environment are in a separate file fenv_private.h included from math_private.h. As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include <fenv_private.h> and peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next <fenv_private.h>. The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of <stdbool.h>, as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/fenv_private.h: New file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the EXCEPTION_TESTS_* macros for individual types out to their own sysdeps header.

In the soft-float case where FE_TONEAREST is the only rounding mode macro defined, there is no need to define ROUNDING_TESTS_*; it is only necessary when rounding modes macros are defined that may not be supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some configurations are just removed, not moved to new math-tests-rounding.h headers; the only architectures needing math-tests-rounding.h are those where the macros are defined in bits/fenv.h because of the possibility of a soft-float compilation using a hard-float glibc with the same ABI (i.e., ARM and RISC-V). The test-*-vlen*.h headers, by using #undef, do not yet follow typo-proof conventions (but they no longer implicitly rely on being included before math-tests.h, and this area can always be cleaned up further in future).

Note that this patch does not include additions to struct tcp_info; there are many other elements in this structure in the Linux kernel that are not included in the glibc version (which was last extended in 2007, it seems). Such additions to the end of the structure may be OK with the expected way it is used (size passed explicitly to the kernel with getsockopt), but in principle any change to the size of a type provided by glibc is an ABI change for external applications / libraries using that type in their ABIs, and has the associated risks of such a change.
