* Avoid excess range overflowing results from cosh, sinh, lgamma (bug 18980).Joseph Myers2015-09-181-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various i386 libm functions return values with excess range and precision; Wilco Dijkstra's patches to make isfinite etc. expand inline cause this pre-existing issue to result in test failures (when e.g. a result that overflows float but not long double gets counted as overflowing for some purposes but not others). This patch addresses those cases arising from functions defined in C, adding a math_narrow_eval macro that forces values to memory to eliminate excess precision if FLT_EVAL_METHOD indicates this is needed, and is a no-op otherwise. I'll convert existing uses of volatile and asm for this purpose to use the new macro later, once i386 has clean test results again (which requires fixes for .S files as well). Tested for x86_64 and x86. Committed. [BZ #18980] * sysdeps/generic/math_private.h: Include <float.h>. (math_narrow_eval): New macro.

This patch renames bits/atomic.h to atomic-machine.h to follow that convention. This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present).

* Fix lgamma (negative) inaccuracy (bug 2542, bug 2543, bug 2558).Joseph Myers2015-09-101-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementations of lgamma functions (except for the ia64 versions) use the reflection formula for negative arguments. This suffers large inaccuracy from cancellation near zeros of lgamma (near where the gamma function is +/- 1). This patch fixes this inaccuracy. For arguments above -2, there are no zeros and no large cancellation, while for sufficiently large negative arguments the zeros are so close to integers that even for integers +/- 1ulp the log(gamma(1-x)) term dominates and cancellation is not significant. Thus, it is only necessary to take special care about cancellation for arguments around a limited number of zeros. Accordingly, this patch uses precomputed tables of relevant zeros, expressed as the sum of two floating-point values. The log of the ratio of two sines can be computed accurately using log1p in cases where log would lose accuracy. The log of the ratio of two gamma(1-x) values can be computed using Stirling's approximation (the difference between two values of that approximation to lgamma being computable without computing the two values and then subtracting), with appropriate adjustments (which don't reduce accuracy too much) in cases where 1-x is too small to use Stirling's approximation directly. In the interval from -3 to -2, using the ratios of sines and of gamma(1-x) can still produce too much cancellation between those two parts of the computation (and that interval is also the worst interval for computing the ratio between gamma(1-x) values, which computation becomes more accurate, while being less critical for the final result, for larger 1-x). Because this can result in errors slightly above those accepted in glibc, this interval is instead dealt with by polynomial approximations. Separate polynomial approximations to (|gamma(x)|-1)(x-n)/(x-x0) are used for each interval of length 1/8 from -3 to -2, where n (-3 or -2) is the nearest integer to the 1/8-interval and x0 is the zero of lgamma in the relevant half-integer interval (-3 to -2.5 or -2.5 to -2). Together, the two approaches are intended to give sufficient accuracy for all negative arguments in the problem range. Outside that range, the previous implementation continues to be used. Tested for x86_64, x86, mips64 and powerpc. The mips64 and powerpc testing shows up pre-existing problems for ldbl-128 and ldbl-128ibm with large negative arguments giving spurious "invalid" exceptions (exposed by newly added tests for cases this patch doesn't affect the logic for); I'll address those problems separately.

On s390-32 (zarch-mode), _Unwind_Word has a size of 8 bytes, too. _Unwind_Word is defined in sysdeps/generic/unwind.h as typedef unsigned _Unwind_Word __attribute__((__mode__(__word__))); In libgcc unwind header (<gcc-src>/libgcc/unwind-generic.h) this typedef has changed to "typedef unsigned _Unwind_Word __attribute__((__mode__(__unwind_word__)));" in June 2008.

Afterwards, the int-to-pointer-cast-warning is gone away on s390-32 (zarch-mode) and the testsuite runs with the same test-failures as s390-32 (esa-mode) plus FAIL: c++-types-check. Here register_t is expected to has a size of 4 bytes, but it has a size of 8 bytes due to: posix/sys/types.h:205:typedef int register_t __attribute__ ((__mode__ (__word__))); The libgcc-patch for gcc 4.4 can be found here: "[PATCH, spu, unwind] Remove attribute ((mode (word))) from unwind.h" https://gcc.gnu.org/ml/gcc-patches/2008-06/msg00969.html ChangeLog: * sysdeps/generic/unwind.h (_Unwind_Word): Use __mode__(__unwind_word__) instead of __mode__(__word__).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | With copy relocation, address of protected data defined in the shared library may be external.

* Fix recursive dlopen.Carlos O'Donell2015-01-211-2/+2
| | | | | | | | | | | | | | | | | | | The ability to recursively call dlopen is useful for malloc implementations that wish to load other dynamic modules that implement reentrant/AS-safe functions to use in their own implementation. Given that a user malloc implementation may be called by an ongoing dlopen to allocate memory the user malloc implementation interrupts dlopen and if it calls dlopen again that's a reentrant call. This patch fixes the issues with the ld.so.cache mapping and the _r_debug assertion which prevent this from working as expected. See: https://sourceware.org/ml/libc-alpha/2014-12/msg00446.html

I don't know if this also causes test failures on SPARC, although I see no reason for it not to do so. This patch fixes this namespace issue. profil_counter is renamed to __profil_counter and made a weak alias on ARM and SPARC. Because of the uses in profil.c / sprofil.c it seems simplest to make the rename globally, including on the other architectures for which profil_counter was static and so the change is of no substance. The variant names profil_counter_* used in sprofil.c are also renamed to start with __ so that undesired function names do not get exported in static libc. As I noted in bug 17726, profil_counter should probably be a compat symbol on ARM and SPARC, so it wouldn't exist at all in static libc even as a weak alias. Since defining a compat symbol still requires an internal name as a target of an alias, this patch still seems reasonable as an intermediate step towards that goal: it wouldn't be possible for the function simply to be static profil_counter on ARM and SPARC with profil_counter also being the exported compat symbol name, so profil.c / sprofil.c would still need to be prepared to call the function under another name (here, __profil_counter). Tested for x86_64 (testsuite, and that stripped installed shared libraries are unchanged by the patch) and ARM (ABI and linknamespace tests - this patch reduces the number of linknamespace failures I see on ARM from 227 to 5, the residue being math.h failures for fe* functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases). 2014-12-17 Joseph Myers <joseph@codesourcery.com> [BZ #17725] * sysdeps/generic/profil-counter.h (profil_counter): Rename to __profil_counter. * sysdeps/unix/sysv/linux/hppa/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/i386/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/ia64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/sh/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/tile/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/x86_64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Likewise.

* Run check-localpltk/textrel/execstack over ld.so.Carlos O'Donell2014-11-061-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386. Verified for i386 Verified for x86_64 Verified for ppc32 Verified for ppc64 Verified for ppc64le Verified for arm Verified for aarch64 Verified for s390 Verified for s390x Guessed for alpha Guessed for ia64 Guessed for m68k Guessed for microblaze Guessed for sparc32 Guessed for sparc64 Defaults for sh Defaults for mips Defaults for hppa Defaults for tile Machine manintainers notified to double check the data used in localplt.data.

* Remove INTDEF / INTUSE / INTVARDEF (bug 14132).Joseph Myers2014-11-051-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Completing the removal of the obsolete INTDEF / INTUSE mechanism, this patch removes the final use - that for _dl_starting_up - replacing it by rtld_hidden_def / rtld_hidden_proto. Having removed the last use, the mechanism itself is also removed. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. (This is not much of a test since this variable is only defined and used in the !HAVE_INLINED_SYSCALLS case.) [BZ #14132] * include/libc-symbols.h (INTUSE): Remove macro. (INTDEF): Likewise.

* Don't use INTDEF/INTUSE with _dl_mcount (bug 14132).Joseph Myers2014-11-051-2/+1
| | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_mcount with use of rtld_hidden_def / rtld_hidden_proto. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. [BZ #14132] * elf/dl-profile.c (_dl_mcount): Use rtld_hidden_def instead of INTDEF. * sysdeps/generic/ldsodefs.h (_dl_mcount_internal): Remove declaration.

* Don't use INTDEF/INTUSE with _dl_argv (bug 14132).Joseph Myers2014-11-041-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_argv with rtld_hidden_data_def and rtld_hidden_proto. Some places in .S files that previously used _dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly (there are plenty of existing examples of such direct use of __GI_*). A single place in rtld.c previously used _dl_argv without INTUSE, apparently accidentally, while the rtld_hidden_proto mechanism avoids such accidential omissions. As a consequence, this patch *does* change the contents of stripped ld.so. However, the installed stripped shared libraries are identical to those you get if instead of this patch you change that single _dl_argv use to use INTUSE, without any other changes. Tested for x86_64 (testsuite as well as comparison of installed stripped shared libraries as described above). [BZ #14132] * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto. [IS_IN_rtld] (_dl_argv_internal): Do not declare. (rtld_progname): Make macro definition unconditional. * elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of INTDEF.

| | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use in unwind-dw2-fde.c with hidden_def and hidden_proto.

* Remove configure tests for assembler CFI support.Joseph Myers2014-06-261-61/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes configure tests for assembler CFI support (and thereby eliminates an architecture-specific case in the main configure.ac), instead assuming that support is present unconditionally. The main test was added in 2003 around the time CFI support was added to the assembler. cfi_personality and cfi_lsda support were added to the assembler in 2006. cfi_sections support was added in 2009, a few weeks before binutils 2.20 was released; it's in 2.20, the minimum supported version, so even that configure test is obsolete. Tested x86_64 that the installed shared libraries are unchanged by this patch. * configure.ac (libc_cv_asm_cfi_directives): Remove configure test. * configure: Regenerated. * config.h.in (HAVE_ASM_CFI_DIRECTIVES): Remove macro undefine. * sysdeps/arm/configure.ac (libc_cv_asm_cfi_directive_sections): Remove configure test. * sysdeps/arm/configure: Regenerated. * sysdeps/nptl/configure.ac: Do not check libc_cv_asm_cfi_directives. * sysdeps/nptl/configure: Regenerated. * sysdeps/x86_64/nptl/configure.ac: Remove file. * sysdeps/x86_64/nptl/configure: Remove generated file. * b/sysdeps/generic/sysdep.h [HAVE_ASM_CFI_DIRECTIVES]: Make code unconditional.

This patch removes such unnecessary kernel-features.h includes.

As a result math functions using SET_RESTORE_ROUND* macros do not suffer from a large slowdown on targets which do not implement optimized libc_fe*_ctx inline functions. Most of the libc_fe* inline functions are now unused and could be removed in the future (there are a few math functions left which use a mixture of standard fenv calls and libc_fe* inline functions - they could be updated to use SET_RESTORE_ROUND or improved to avoid expensive fenv manipulations across just a few FP instructions). libc_feholdsetround*_noex_ctx is added to enable better optimization of SET_RESTORE_ROUND_NOEX* implementations. Performance measurements on ARM and x86 of sin() show significant gains over the current default, fairly close to a highly optimized fenv_private: ARM x86 no fenv_private : 100% 100% generic HAVE_RM_CTX : 250% 350% fenv_private (CTX) : 250% 450% 2014-06-23 Will Newton <will.newton@linaro.org> Wilco <wdijkstr@arm.com> * sysdeps/generic/math_private.h: Add generic HAVE_RM_CTX implementation.

[!libc_feholdsetround_noexf_ctx]: Define libc_feholdsetround_noexf_ctx. [!libc_feholdsetround_noexl_ctx]: Define libc_feholdsetround_noexl_ctx. (libc_feholdsetround_ctx): New function. (libc_feresetround_ctx): New function. (libc_feholdsetround_noex_ctx): New function. (libc_feresetround_noex_ctx): New function.
* Add fallback file for elide.hAndi Kleen2014-06-141-0/+25
| | | | | | Add the missing fallback file for elide.h to fix non x86 builds. Sorry about that. This is just a noop macro file that makes all elision code to be optimized out.
