* Consolidate vDSO macros and usageAdhemerval Zanella2015-05-2626-552/+288
| | | | | | | | | | | | | | | | This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.
* Remove socket.S implementationAdhemerval Zanella2015-05-2261-1718/+609
| | | | | | | | | | | | | | | This patch removes the socket.S implementation for all ports and replace it by a C implementation using socketcall. For ports that implement the syscall directly, there is no change. The patch idea is to simplify the socket function implementation that uses the socketcall to be based on C implemetation instead of a pseudo assembly implementation with arch specific parts. The patch then remove the assembly implementatation for the ports which uses socketcall (i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh). I have cross-build GLIBC for afore-mentioned ports and tested on both i386 and ppc32 without regressions.
* Fix ldbl-128 / ldbl-128ibm tanl for -Wuninitialized.Joseph Myers2015-05-222-0/+24
| | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of tanl produce uninitialized variable warnings with -Wuninitialized because of a variable that is initialized only conditionally, then used under the same conditions under which it is set. This patch uses DIAG_* macros to suppress those warnings. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/k_tanl.c: Include <libc-internal.h>. (__kernel_tanl): Ignore uninitialized warnings around use of SIGN. * sysdeps/ieee754/ldbl-128ibm/k_tanl.c: Include <libc-internal.h>. (__kernel_tanl): Ignore uninitialized warnings around use of SIGN.
* Fix ldbl-128 / ldbl-128ibm erfcl for -WuninitializedJoseph Myers2015-05-222-2/+2
| | | | | | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of erfcl produce uninitialized variable warnings with -Wuninitialized because of switch statements where in fact one of the cases will always be executed, but the compiler does not see that these cases cover all possibilities (and because the reasoning that it does involves inequalities on the representation of a floating point value leading to a set of possible values for 8.0 times that value, converted to int, it's highly nontrivial for the compiler to see that). This patch fixes those warnings by converting the last case in those switch statements to a "default" case. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/s_erfl.c (__erfcl): Make case 9 in switch statement into default case. * sysdeps/ieee754/ldbl-128ibm/s_erfl.c (__erfcl): Likewise.
* Fix ldbl-128 / ldbl-128ibm asinl for -Wuninitialized.Joseph Myers2015-05-222-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ldbl-128 and ldbl-128ibm implementations of asinl produce uninitialized variable warnings with -Wuninitialized because the code for small arguments in fact always returns but the compiler cannot see this and instead sees that a variable would be uninitialized if the "if (huge + x > one)" conditional used to force the "inexact" exception were false. All the code in libm trying to force "inexact" for functions that are not exactly defined is suspect and should be removed at some point given that we now have a clear definition of the accuracy goals for libm functions which, following C99/C11, does not require anything about "inexact" for most functions (likewise, the multi-precision code that tries to give correctly-rounded results, very slowly, for functions for which the goals clearly do not include correct rounding, if the faster paths are accurate enough). However, for now this patch simply changes the code to use math_force_eval, rather than "if", to ensure the evaluation of the inexact computation. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/e_asinl.c (__ieee754_asinl): Don't use a conditional in forcing "inexact". * sysdeps/ieee754/ldbl-128ibm/e_asinl.c (__ieee754_asinl): Likewise.
* Fix pathconf basename namespace (bug 18444).Joseph Myers2015-05-221-1/+1
| | | | | | | | | | | | | | | | | | | | | pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename. But pathconf is in POSIX back to 1990 while basename is only reserved with external linkage in those standards including XPG functions. This patch fixes this namespace issue in the usual way, renaming basename to __basename and making it into a weak alias. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #18444] * string/basename.c (basename): Rename to __basename and define as weak alias of __basename. Use libc_hidden_weak. * include/string.h (__basename): Declare. Use libc_hidden_proto. * sysdeps/unix/sysv/linux/pathconf.c (distinguish_extX): Call __basename instead of basename. * conform/Makefile (test-xfail-POSIX2008/unistd.h/linknamespace): Remove variable.

* Fix lgamma implementations for -Wuninitialized.Joseph Myers2015-05-213-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you remove the "override CFLAGS += -Wno-uninitialized" in math/Makefile, you get errors from lgamma implementations of the form: ../sysdeps/ieee754/dbl-64/e_lgamma_r.c: In function '__ieee754_lgamma_r': ../sysdeps/ieee754/dbl-64/e_lgamma_r.c:297:13: error: 'nadj' may be used uninitialized in this function [-Werror=maybe-uninitialized] if(hx<0) r = nadj - r; This is one of the standard kinds of false positive uninitialized warnings: nadj is set under a certain condition, and then later used under the same condition. This patch uses DIAG_* macros to suppress the warning on the use of nadj. The ldbl-128 / ldbl-128ibm implementation has a substantially different structure that avoids this issue. Tested for x86_64. (In fact this patch eliminates the need for that -Wno-uninitialized on x86_64, but I want to test on more architectures before removing it.) * sysdeps/ieee754/dbl-64/e_lgamma_r.c: Include <libc-internal.h>. (__ieee754_lgamma_r): Ignore uninitialized warnings around use of NADJ. * sysdeps/ieee754/flt-32/e_lgammaf_r.c: Include <libc-internal.h>.

* Fix sysdeps/ieee754/dbl-64/mpa.c for -Wuninitialized.Joseph Myers2015-05-211-2/+3
| | | | | | | | | | | | | | | | | | | | If you remove the "override CFLAGS += -Wno-uninitialized" in math/Makefile, one of the errors you get is: ../sysdeps/ieee754/dbl-64/mpa.c: In function '__mp_dbl.part.0': ../sysdeps/ieee754/dbl-64/mpa.c:183:5: error: 'c' may be used uninitialized in this function [-Werror=maybe-uninitialized] c *= X[0]; The problem is that the p < 5 case initializes c if p is 1, 2, 3 or 4 but not otherwise, and in fact p is positive for all calls to this function so the uninitialized case can't actually occur. This patch replaces the "if (p == 4)" last case with a comment so the compiler can see that all paths do initialize c. Tested for x86_64. * sysdeps/ieee754/dbl-64/mpa.c (norm): Remove if condition on (p == 4) case.

* i386: Remove six-argument specialized implementationsAdhemerval Zanella2015-05-205-197/+2
| | | | | | This patch removes the specialized i386 assembly implementations for fallocate{64}, pselect, and sync_file_range now that i386 have support for 6 argument syscalls.
* Fix ldbl-96 remquol (finite, Inf) (bug 18244).Joseph Myers2015-05-191-1/+1
| | | | | | | | | | | | | | | | | | ldbl-96 remquol wrongly handles the case where the first argument is finite and the second infinite, because the check for the second argument being a NaN fails to disregard the explicit high mantissa bit and so wrongly interprets an infinity as being a NaN. This patch fixes this by masking off that bit, and improves test coverage for both remainder and remquo (various cases were missing tests, or, as in the case of the bug, were tested only for one of the two functions). Tested for x86_64 and x86. [BZ #18244] * sysdeps/ieee754/ldbl-96/s_remquol.c (__remquol): Ignore explicit high mantissa bit when testing whether P is a NaN. * math/libm-test.inc (remainder_test_data): Add more tests. (remquo_test_data): Likewise.
* Fix i386 atanhl spurious underflows (bug 18049).Joseph Myers2015-05-191-0/+10
| | | | | | | | | | | | | | | | The i386 implementation of atanhl, for small arguments, does a calculation that involves computing twice the square of the argument, resulting in spurious underflows for some arguments. This patch fixes this by just returning the argument when its exponent is below -32, with underflow being forced as needed for subnormal arguments. Tested for x86 and x86_64. [BZ #18049] * sysdeps/i386/fpu/e_atanhl.S (__ieee754_atanhl): For exponents below -32, return the argument, with underflow if subnormal. * math/auto-libm-test-in: Add more tests of atanh. * math/auto-libm-test-out: Regenerated.

* Fix atanhl missing underflows (bug 16352).Joseph Myers2015-05-157-4/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to various other bugs in this area, some atanh implementations do not raise the underflow exception for subnormal arguments, when the result is tiny and inexact. This patch forces the exception in a similar way to previous fixes. (No change in this regard is needed for the i386 implementation; special handling to force underflows in these cases will only be needed there when the spurious underflows, bug 18049, get fixed.)

* Fix tanf spurious underflows (bug 18221).Joseph Myers2015-05-151-1/+1
| | | | | | | | | | | | | | | | The flt-32 implementation of tanf produces spurious underflow exceptions for some small arguments, through computing values on the order of x^5. This patch fixes this by adjusting the threshold for returning x (or, as applicable, +/- 1/x) to 2**-13 (the next term in the power series being x^3/3). Tested for x86_64 and x86. [BZ #18221] * sysdeps/ieee754/flt-32/k_tanf.c (__kernel_tanf): Use 2**-13 not 2**-28 as threshold for returning x or +/- 1/x. * math/auto-libm-test-in: Add more tests of tan. * math/auto-libm-test-out: Regenerated.
* Fix lgammaf spurious underflows (bug 18220).Joseph Myers2015-05-151-3/+3
| | | | | | | | | | | | | | | | | The flt-32 implementation of lgammaf produces spurious underflow exceptions for some large arguments, because of calculations involving x^-2 multiplied by small constants. This patch fixes this by adjusting the threshold for a simpler computation to 2**26 (the error in the simpler computation is on the order of 0.5 * log (x), for a result on the order of x * log (x)). Tested for x86_64 and x86. [BZ #18220] * sysdeps/ieee754/flt-32/e_lgammaf_r.c (__ieee754_lgammaf_r): Use 2**26 not 2**58 as threshold for returning x * (log (x) - 1). * math/auto-libm-test-in: Add another test of lgamma. * math/auto-libm-test-out: Regenerated.

* Fix erfcf spurious underflows (bug 18217).Joseph Myers2015-05-151-1/+1
| | | | | | | | | | | | | | | | | | The flt-32 implementation of erfcf produces spurious underflow exceptions for some arguments close to 0, because of calculations squaring the argument and then multiplying by small constants. This patch fixes this by adjusting the threshold for arguments for which the result is so close to 1 that 1 - x will give the right result from 2**-56 to 2**-26. (If 1 - x * 2/sqrt(pi) were used, the errors would be on the order of x^3 and a much larger threshold could be used.) Tested for x86_64 and x86. [BZ #18217] * sysdeps/ieee754/flt-32/s_erff.c (__erfcf): Use 2**-26 not 2**-56 as threshold for returning 1 - x. * math/auto-libm-test-in: Add more tests of erfc. * math/auto-libm-test-out: Regenerated.
* Fix atanf spurious underflows (bug 18196).Joseph Myers2015-05-141-1/+1
| | | | | | | | | | | | | | | | The sysdeps/ieee754/flt-32 version of atanf produces spurious underflow exceptions for some large arguments, because of computations that compute x^-4. This patch fixes this by adjusting the threshold for large arguments (for which +/- pi/2 can just be returned, the correct result being roughly +/- pi/2 - 1/x) from 2^34 to 2^25. Tested for x86_64 and x86. [BZ #18196] * sysdeps/ieee754/flt-32/s_atanf.c (__atanf): Use 2^25 not 2^34 as threshold for large arguments. * math/auto-libm-test-in: Add another test of atan. * math/auto-libm-test-out: Regenerated.

This patch forces the exception in a similar way to previous fixes. (The ldbl-128ibm implementation doesn't currently need any change as it already generates this exception, albeit through code that would generate spurious exceptions in other cases; special code for this issue will only be needed there when fixing the spurious exceptions.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To make a strtok faster and improve performance in general we need to do one additional change. A comment: /* It doesn't make sense to send libc-internal strcspn calls through a PLT. The speedup we get from using SSE4.2 instruction is likely eaten away by the indirect call in the PLT. */ Does not make sense at all because nobody bothered to check it. Gap between these implementations is quite big, when haystack is empty a sse2 is around 40 cycles slower because it needs to populate a lookup table and difference only increases with size.

* Fix mips16 __fpu_control static linking (bug 18397).Joseph Myers2015-05-112-1/+4
| | | | | | | | | | | | | | | | | | | | | Programs are supposed to be able to define the __fpu_control variable, overriding the library's version to cause the floating-point control word to be set to the chosen value at startup. This is broken for mips16 for static linking because the library's __fpu_control variable is in the same object file as the helper functions used by fpu_control.h for mips16, so test-fpucw-ieee-static fails to link with multiple definitions of __fpu_control. This patch fixes this by putting the helpers in a separate file rather than overriding fpu_control.c. Tested for mips16 that this fixes the link failure and the ABI tests still pass.

* Bug 18125: Call exit after last linked context.Carlos O'Donell2015-05-084-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There appears to be a discrepancy among the implementations of setcontext with regards to the function called once the last linked-to context has finished executing via setcontext. The POSIX standard says: ~~~ If the uc_link member of the ucontext_t structure pointed to by the ucp argument is equal to 0, then this context is the main context, and the thread will exit when this context returns. ~~~ It says "exit" not "exit immediately" nor "exit without running functions registered with atexit or on_exit." Therefore the AArch64, ARM, hppa and NIOS II implementations are wrong and no test detects it. It is questionable if this should even be fixed or just documented that the above 4 targets are wrong. The functions are deprecated and nobody should be using them, but at the same time it silly to have cross-target differences that make it hard to port old applications from say x86_64 to AArch64. Therefore I will ix the 4 arches, and checkin a regression test to prevent it from changing again. https://sourceware.org/ml/libc-alpha/2015-03/msg00720.html

| | | | | | | | | | | | | | | | | This patch adds more randomly-generated tests of various libm functions that are observed to increase ulps on x86_64. (This process must eventually converge, when my random test generation stops finding inputs that increase the listed ulps, except maybe for any cases uncovered where the errors exceed the maximum allowed 9ulp error and so indicate actual libm bugs needing fixing.) Tested for x86_64 and x86 and ulps updated accordingly. * math/auto-libm-test-in: Add more tests of acosh, atanh, clog, clog10, csqrt, erfc, exp2, expm1, log10, log2 and sinh. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
* __ASSUME_FALLOCATE is always true on 32-bit architecturesFlorian Weimer2015-05-055-114/+34
| | | | | This means we can clean up the generic code a bit. The 64-bit variant still needs to support !__ASSUME_FALLOCATE for alpha.
* i386: Remove fallocate, fallocate64, posix_fallocate, posix_fallocate64Florian Weimer2015-05-056-232/+3
| | | | | With 6-argument system call support, the generic Linux implementations of these system calls work, and there is no need for i386-specific versions.
