* Move mips from ports to libc.Joseph Myers2014-02-10363-0/+58942
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips.

* Move tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf2014-02-10271-0/+28727
| | | | | | | | | | | | | | | | I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've moved the ARM port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/arm sysdeps/arm git mv ports/sysdeps/unix/arm sysdeps/unix/arm git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.arm similar to that at the top of ChangeLog.powerpc. There is deliberately no NEWS change, as I think it makes the most sense to put in a general note above all ports having moved if we can achieve that for 2.20. Tested that disassembly of installed shared libraries for arm is the same before and after this patch, except for data (not instructions) in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the path by which that file is found, and so by which it appears in the assertion message, changes as a result of the move). * sysdeps/arm: Move directory from ports/sysdeps/arm. * sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm. * sysdeps/unix/sysv/linux/arm: Move directory from ports/sysdeps/unix/sysv/linux/arm. * README: Update listing for arm-*-linux-gnueabi. ports/ChangeLog.arm: * sysdeps/arm: Move directory to ../sysdeps/arm. * sysdeps/unix/arm: Move directory to ../sysdeps.arm. * sysdeps/unix/sysv/linux/arm: Move directory to ../sysdeps/unix/sysv/linux/arm.

* Fix tst-setgetname for Linux kernels < 2.6.33.Carlos O'Donell2014-02-051-0/+6
| | | | | | | | Support for /proc/self/task/$tid/comm as added in Linux 2.6.33, therefore since the test tst-setgetname relies on this functionality to operate we must skip the test in kernels < 2.6.33. We wrap the checks with __ASSUME_PROC_PID_TASK_COMM such that in the future when we move arch_minimum_kernel to 2.6.33 we can remove this code.

* Disable x87 inline functions for SSE2 mathH.J. Lu2014-01-291-2/+2
| | | | | | | When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.

* PowerPC: Fix gettimeofday ifunc selectionAdhemerval Zanella2014-01-202-4/+10
| | | | | | | | | | | | The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where __vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal version used within GLIBC) to use the system call version instead of the vDSO one. This patch changes the check if vDSO is available to get its value directly instead of rely on __vdso_gettimeofday. This patch changes it by getting the vDSO value directly. It fixes BZ#16431.
* s390: implement sotruss supportMike Frysinger2014-01-161-0/+62
| | | | | | | | | | | | | See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase. Note: while this works on s390x, the s390 code hangs when using -e. But it hangs regardless of this code (the hang seems to occur before the exit func is even called). I didn't look too closely at it as it seems to be an issue external to this file, so this code shouldn't make the situation any worse.

* PowerPC: Fix ftime gettimeofday internal call returning bogus dataAdhemerval Zanella2014-01-162-4/+36
| | | | | | | | | | | | This patches fixes BZ#16430 by setting a different symbol for internal GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol is defined as hidden (which is the case for gettimeofday and time) the compiler will create local branches (symbol@local) and linker will not create PLT calls (required for IFUNC). This will leads to internal symbol calling the IFUNC resolver instead of the resolved symbol. For PPC64 this behavior does not occur because a call to a function in another translation unit might use a different toc pointer thus requiring a PLT call.

* Do not enable asynchronous cancellation in system. Fixes bug 14782.Ondřej Bílka2014-01-151-10/+1

* PowerPC: remove wrong truncl implementation for PowerPC64Adhemerval Zanella2014-01-082-123/+0
| | | | | | | | | | | | | | | The truncl assembly implementation (sysdeps/powerpc/powerpc64/fpu/s_truncl.S) returns wrong results for some inputs where first double is a exact integer and the precision is determined by second long double. Checking on implementation comments and history, I am very confident the assembly implementation was based on a version before commit 5c68d401698a58cf7da150d9cce769fa6679ba5f that fixes BZ#2423 (Errors in long double (ldbl-128ibm) rounding functions in glibc-2.4). By just removing the implementation and make the build select sysdeps/ieee754/ldbl-128ibm/s_truncl.c instead it fixes tgammal issues regarding wrong result sign.

* Fix ldbl-128ibm expm1l on large arguments (bug 16408).Joseph Myers2014-01-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16408, ldbl-128ibm expm1l returning NaN for some large arguments. The basic problem is that the approach of converting the exponent to the form n * log(2) + y, where -0.5 <= y <= 0.5, then computing 2^n * expm1(y) + (2^n - 1) falls over when 2^n overflows (starting slightly before the point where expm1 overflows, when y is negative and n is the least integer for which 2^n overflows). The ldbl-128 code, and the x86/x86_64 code, make expm1l fall back to expl for large positive arguments to avoid this issue. This patch makes the ldbl-128ibm code do the same. (The problem appears for the particular argument in the testsuite because the ldbl-128ibm code also uses an overflow threshold that's for ldbl-128 and is too big for ldbl-128ibm, but the problem described applies for large non-overflowing cases as well, although during the freeze is not a suitable time for making the expm1 tests cover cases close to overflow more thoroughly.) This leaves some code for large positive arguments in expm1l that is now dead. To keep the code for ldbl-128 and ldbl-128ibm similar, and to avoid unnecessary changes during the freeze, the patch doesn't remove it; instead I propose to file a bug in Bugzilla as a reminder that this code (for overflow, including errno setting, and for arguments of +Inf) is no longer needed and should be removed from both those expm1l implementations. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/s_expm1l.c (__expm1l): Use __expl for large positive arguments.

* Fix ldbl-128ibm coshl spurious overflows (bug 16407).Joseph Myers2014-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16407, spurious overflows from ldbl-128ibm coshl. The implementation assumed that a high part (reinterpreted as an integer) of the absolute value of the argument of 0x408633ce8fb9f87dLL or more meant overflow, but the actual threshold has high part 0x408633ce8fb9f87eLL (and a negative low part). The patch adjusts the threshold accordingly. sinhl probably has the same issue, but I didn't get that far in adding tests of special cases (such as just below and above overflow) before the freeze and during the freeze is not a suitable time to add them (as they'd require ulps to be regenerated again), so I'm not changing that function for now; when I add more tests of special cases, we'll discover whether sinhl indeed has this problem. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/e_coshl.c (__ieee754_coshl): Increase overflow threshold.

* Fix ldbl-128 / ldbl-128ibm lgammal spurious underflow (bug 16400).Joseph Myers2014-01-061-1/+3
| | | | | | | | | | | | | | This patch fixes bug 16400, spurious underflow exceptions for ldbl-128 / ldbl-128ibm lgammal with small positive arguments, by just using -__logl (x) as the result in the problem cases (similar to the previous fix for problems with small negative arguments). Tested powerpc32, and also tested on mips64 that this does not require ulps regeneration for the ldbl-128 case. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Return -__logl (x) for small positive arguments without evaluating a polynomial.
