2016-01-28Fix MIPS64 memcpy regression.Steve Ellcey
The MIPS memcpy optimizations at <https://sourceware.org/ml/libc-alpha/2015-10/msg00597.html> introduced a bug causing many string function tests to fail with segfaults for n32 and n64: FAIL: string/stratcliff FAIL: string/test-bcopy FAIL: string/test-memccpy FAIL: string/test-memcmp FAIL: string/test-memcpy FAIL: string/test-memmove FAIL: string/test-mempcpy FAIL: string/test-stpncpy FAIL: string/test-strncmp FAIL: string/test-strncpy (Some failures in other directories could also be caused by this bug.) The problem is that after the check for whether a word of input is left that can be copied as a word before moving to byte copies, a load can occur in the branch delay slot, resulting in a segfault if we are at the end of a page and the following page is unmapped. I don't see how this would have passed the tests as reported in the original patch posting (different kernel configurations affecting the code setting up unmapped pages, maybe?), since the tests in question don't appear to have changed recently. This patch moves a later instruction into the delay slot, as suggested at <https://sourceware.org/ml/libc-alpha/2016-01/msg00584.html>. Tested for n32 and n64. 2016-01-28 Steve Ellcey <sellcey@imgtec.com> Joseph Myers <joseph@codesourcery.com> * sysdeps/mips/memcpy.S (MEMCPY_NAME) [USE_DOUBLE]: Avoid word load in branch delay slot when less than a word of input left.

2015-02-16Fix MIPS _COMPILING_NEWLIB -Werror=undef build.Joseph Myers
I see an error ../sysdeps/mips/strcmp.S:25:7: error: "_COMPILING_NEWLIB" is not defined [-Werror=undef] #elif _COMPILING_NEWLIB ^ cc1: some warnings being treated as errors in MIPS builds. (This is with GCC 4.9; it's possible that the DR#412 change in GCC 5 - see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60570> - means that -Wundef diagnostics no longer occur for #elif conditions where a previous group's condition was true, just as with other errors there.) This patch duly adjusts the conditionals to test whether _COMPILING_NEWLIB is defined. * sysdeps/mips/memcpy.S [_COMPILING_NEWLIB]: Change condition to [defined _COMPILING_NEWLIB]. * sysdeps/mips/memset.S [_COMPILING_NEWLIB]: Likewise. * sysdeps/mips/strcmp.S [_COMPILING_NEWLIB]: Likewise.

2014-02-10Move mips from ports to libc.Joseph Myers
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.
