* RISC-V: Add ABI ListsPalmer Dabbelt2018-01-2919-0/+8087
| | | | | | | | | | | | | | | | | | | | | | | I started with the aarch64 ABI lists and manually went through each difference, ensuring that the missing entries had been deprecated along the line. Darius generated the ulps files by running the test cases on QEMU. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/nofpu/libm-test-ulps: New file. * sysdeps/riscv/nofpu/libm-test-ulps-name: Likewise. * sysdeps/riscv/rv64/rvd/libm-test-ulps: Likewise. * sysdeps/riscv/rv64/rvd/libm-test-ulps-name: Likewise. * sysdeps/unix/sysv/linux/riscv/localplt.data: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/c++-types.data: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/ld.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libanl.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libdl.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libnsl.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/librt.abilist: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/libutil.abilist: Likewise.

| | | | | | | | | | | | | This patch implements various atomic and locking routines on RISC-V.

* sysdeps/init_array: Add PREINIT_FUNCTION to crti.SPalmer Dabbelt2018-01-291-0/+14
| | | | | | | | | | | | | The RISC-V port contains a crti.S that simply contains a link to PREINIT_FUNCTION (when defined). As this should be entirely generic, Joseph Myers suggested that we update the generic init_array version to contain this. Since RISC-V is the only user of init_array this won't break any existing ports. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/init_array/crti.S (.section .init_array): Add PREINIT_FUNCTION when defined.

* Revert Intel CET changes to __jmp_buf_tag (Bug 22743)Carlos O'Donell2018-01-259-103/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit cba595c350e52194e10c0006732e1991e3d0803b and commit f81ddabffd76ac9dd600b02adbf3e1dac4bb10ec, ABI compatibility with applications was broken by increasing the size of the on-stack allocated __pthread_unwind_buf_t beyond the oringal size. Applications only have the origianl space available for __pthread_unwind_register, and __pthread_unwind_next to use, any increase in the size of __pthread_unwind_buf_t causes these functions to write beyond the original structure into other on-stack variables leading to segmentation faults in common applications like vlc. The only workaround is to version those functions which operate on the old sized objects, but this must happen in glibc 2.28. Thank you to Andrew Senkevich, H.J. Lu, and Aurelien Jarno, for submitting reports and tracking the issue down. The commit reverts the above mentioned commits and testing on x86_64 shows that the ABI compatibility is restored. A tst-cleanup1 regression test linked with an older glibc now passes when run with the newly built glibc. Previously a tst-cleanup1 linked with an older glibc would segfault when run with an affected glibc build. Tested on x86_64 with no regressions. Signed-off-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | The arguments of the LIBC_SLIBDIR_RTLDDIR macro are used both in unquoted and single quoted context, so that neither shell nor makefile variable references work. Consistently put them in single quotes so that they can refer to makefile variables.
* Add localplt.data for ColdFire.Joseph Myers2018-01-242-0/+18
| | | | | | | | | | | | | | | The sole failure for ColdFire in the compilation part of the glibc testsuite is the localplt test. This patch adds a localplt baseline for ColdFire to eliminate that failure. The difference from the existing m68k baseline is that no PLT entry for _Unwind_Find_FDE is expected, because ColdFire does not set libc_cv_gcc_unwind_find_fde=yes. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/m68k/localplt.data: Move to .... * sysdeps/unix/sysv/linux/m68k/m680x0/localplt.data: ... here. * sysdeps/unix/sysv/linux/m68k/coldfire/localplt.data: New file.
* Add no-FPU ColdFire math_private.h.Joseph Myers2018-01-241-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | As with some other soft-float configurations, no-FPU ColdFire needs various fenv.h functions and glibc-internal macros overridden in math_private.h to avoid references to undefined FE_* macros when building glibc. This patch adds a suitable math_private.h, based on the MicroBlaze one (Nios II and Tile also have similar files). There's a case for having such a file in sysdeps/ieee754/soft-fp so this logic is applied more generally to configurations without exceptions and rounding modes, even when the relevant macros are defined in fenv.h - the only case where that might be inappropriate is ARM soft-float (where the fenv.h functions might or might not work at runtime, depending on whether the processor used at runtime supports VFP). There's also a case that soft-float configurations (on processors with both hard-float and soft-float) should more consistently avoid defining FE_* macros in bits/fenv.h when not actually supported. But both of those are separate potential cleanups. This allows the no-FPU ColdFire build to get further (another fix is needed to allow the build to complete). * sysdeps/m68k/coldfire/nofpu/math_private.h: New file. Based on MicroBlaze file.
* Add jmp_buf-macros.h for no-FPU ColdFire.Joseph Myers2018-01-242-0/+6
| | | | | | | | | | | | | | | Continuing the fixes for ColdFire glibc build with build-many-glibcs.py, given a GCC patch for the libgcc build failure, this patch adds jmp_buf-macros.h for no-FPU ColdFire. This allows the no-FPU build to progress further than without the patch (although other fixes are still needed for the build to complete). * sysdeps/unix/sysv/linux/m68k/coldfire/jmp_buf-macros.h: Move to .... * sysdeps/unix/sysv/linux/m68k/coldfire/fpu/jmp_buf-macros.h: ... here. * sysdeps/unix/sysv/linux/m68k/coldfire/nofpu/jmp_buf-macros.h: New file.
* Add jmp_buf-macros.h for ColdFire.Joseph Myers2018-01-242-0/+6
| | | | | | | | | | | | | | | | | | | | | | This patch adds a jmp_buf-macros.h for ColdFire. In conjunction with a GCC patch to fix the libgcc build failure for ColdFire <https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02064.html> this suffices to restore the build (tested with build-many-glibcs.py). A further patch will be needed for soft-float ColdFire (while the function-calling ABI is the same for hard-float and soft-float ColdFire, it turns out the glibc ABI is not - so another ColdFire variant will be needed in build-many-glibcs.py), but I'll deal with that separately. Tested with build-many-glibcs.py (m68k-linux-gnu and m68k-linux-gnu-coldfire). (There's a localplt test failure for coldfire; that's the only failure in the compilation part of the testsuite.) * sysdeps/unix/sysv/linux/m68k/jmp_buf-macros.h: Move to .... * sysdeps/unix/sysv/linux/m68k/m680x0/jmp_buf-macros.h: ... here. * sysdeps/unix/sysv/linux/m68k/coldfire/jmp_buf-macros.h: New file.
* aarch64: Revert the change of the __reserved member of mcontext_tSzabolcs Nagy2018-01-242-2/+6
| | | | | | | | | | | | | | | | | | | | | | The uc_mcontext.__reserved member of ucontext_t is a user visible API, that should not be changed, because this is the only way to access cpu states of various extensions of linux asm/sigcontext.h, it does not violate namespace rules either, so revert this part of the commit commit 4fa9b3bfe6759c82beb4b043a54a3598ca467289 Commit: Joseph Myers <joseph@codesourcery.com> Fix mcontext_t sigcontext namespace (bug 21457). (In principle the user can type cast &uc_mcontext to struct sigcontext* to use the linux sigcontext fields, but that's not the existing practice since mcontext_t used to be a typedef of struct sigcontext.) [BZ #22742] * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (__glibc_reserved1): Rename to __reserved and add comment. * sysdeps/unix/sysv/linux/aarch64/ucontext_i.sym (__glibc_reserved1): Rename to __reserved.
* powerpc: Fix syscalls during early process initialization [BZ #22685]Tulio Magno Quites Machado Filho2018-01-193-4/+36
| | | | | | | | | | | | | | | | | | | | | | | | | The tunables framework needs to execute syscall early in process initialization, before the TCB is available for consumption. This behavior conflicts with powerpc{|64|64le}'s lock elision code, that checks the TCB before trying to abort transactions immediately before executing a syscall. This patch adds a powerpc-specific implementation of __access_noerrno that does not abort transactions before the executing syscall. Tested on powerpc{|64|64le}. [BZ #22685] * sysdeps/powerpc/powerpc32/sysdep.h (ABORT_TRANSACTION_IMPL): Renamed from ABORT_TRANSACTION. (ABORT_TRANSACTION): Redirect to ABORT_TRANSACTION_IMPL. * sysdeps/powerpc/powerpc64/sysdep.h (ABORT_TRANSACTION, ABORT_TRANSACTION_IMPL): Likewise. * sysdeps/unix/sysv/linux/powerpc/not-errno.h: New file. Reuse Linux code, but remove the code that aborts transactions. Signed-off-by: Tulio Magno Quites Machado Filho <tuliom@linux.vnet.ibm.com> Tested-by: Aurelien Jarno <aurelien@aurel32.net>

* Fix backtrace for hppa (bug 22719).Joseph Myers2018-01-171-0/+1
| | | | | | | | | | | | | | | | | | | The only architecture in glibc that uses the generic debug/backtrace.c is hppa. The debug/tst-backtrace* tests fail for hppa, so in fact the generic debug/backtrace.c is not functional anywhere. Instead, the x86_64 version is a reasonably generic version that uses _Unwind_Backtrace from libgcc to backtrace using unwind info, and is used by several architectures. This patch adds hppa to the architectures using it (leaving open the possibility of a subsequent cleanup for 2.28 of moving the x86_64 version to debug/backtrace.c, and removing all the frame.h files that are now unused). Reported by Adhemerval in <https://sourceware.org/ml/libc-alpha/2018-01/msg00564.html> that this does fix the backtrace test failures for hppa. [BZ #22719] * sysdeps/hppa/backtrace.c: New file.
* x86-64: Properly align La_x86_64_retval to VEC_SIZE [BZ #22715]H.J. Lu2018-01-171-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | _dl_runtime_profile calls _dl_call_pltexit, passing a pointer to La_x86_64_retval which is allocated on stack. The lrv_vector0 field in La_x86_64_retval must be aligned to size of vector register. When allocating stack space for La_x86_64_retval, we need to make sure that the address of La_x86_64_retval + RV_VECTOR0_OFFSET is aligned to VEC_SIZE. This patch checks the alignment of the lrv_vector0 field and pads the stack space if needed. Tested with x32 and x86-64 on SSE4, AVX and AVX512 machines. It fixed FAIL: elf/tst-audit10 FAIL: elf/tst-audit4 FAIL: elf/tst-audit5 FAIL: elf/tst-audit6 FAIL: elf/tst-audit7 on x32 AVX512 machine. [BZ #22715] * sysdeps/x86_64/dl-trampoline.h (_dl_runtime_profile): Properly align La_x86_64_retval to VEC_SIZE.
* Use LIBGCC_S_SO in x86_64 backtrace.Joseph Myers2018-01-161-1/+2
| | | | | | | | | | | | | | The x86_64 backtrace implementation is used as a generic implementation (unwinding via unwind info and _Unwind_Backtrace) by various other architectures. This patch makes it more generic by making it use LIBGCC_S_SO from gnu/lib-names.h instead of hardcoding the libgcc_s.so.1 name, so that it can also be used on hppa which uses libgcc_s.so.4. Tested for x86_64. * sysdeps/x86_64/backtrace.c: Include <gnu/lib-names.h>. (init): Use LIBGCC_S_SO not hardcoded "libgcc_s.so.1".
