* Fix m68k bits/fenv.h for no-FPU ColdFire.Joseph Myers2018-02-011-11/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The m68k bits/fenv.h is in sysdeps/m68k/fpu/, meaning that no-FPU ColdFire instead gets the generic (top-level) bits/fenv.h. That top-level bits/fenv.h defines no rounding mode constants. That no longer works for building glibc tests: some tests fail to build (at least with warnings) if no rounding mode macros are defined, so at least FE_TONEAREST must be defined in all cases (as various architectures without rounding mode support indeed do), while __FE_UNDEFINED must be defined in the case where not all the standard rounding modes are supported. On general principles of supporting multilib toolchains with a single set of headers shared between multilibs for a given architecture, it's also desirable for the same bits/fenv.h header to work for both FPU and no-FPU configurations. Thus, this patch moves the m68k bits/fenv.h to sysdeps/m68k/bits/fenv.h, and inserts appropriate conditionals to handle the no-FPU case. All the exception macros, and FE_NOMASK_ENV, are disabled in the no-FPU case; FE_ALL_EXCEPT is defined to 0 in that case. All rounding modes except FE_TONEAREST are disabled in that case, and __FE_UNDEFINED is defined accordingly. To avoid an unnecessary ABI change, fenv_t is defined in the no-FPU case to match the definition it would have got from the generic bits/fenv.h. This suffices to get a clean glibc and testsuite build for this configuration with build-many-glibcs.py (and keeps a clean build for the other m68k configurations); it has not been otherwise tested. * sysdeps/m68k/fpu/bits/fenv.h: Move to .... * sysdeps/m68k/bits/fenv.h: ... here.

* Fix -Os log1p, log1pf build (bug 21314).Carlos O'Donell2018-02-012-3/+26
| | | | | | | | | | | | | | | | | | | | | | As reported in bug 21314, building log1p and log1pf fails with -Os because of a spurious -Wmaybe-uninitialized warning (reported there for GCC 5 for MIPS, I see it also with GCC 7 for x86_64). This patch, based on the patches in the bug, fixes this using the DIAG_* macros. Tested for x86_64 with -Os that this eliminates those warnings and so allows the build to progress further. 2018-02-01 Carlos O'Donell <carlos@redhat.com> Ramin Seyed-Moussavi <lordrasmus@gmail.com> Joseph Myers <joseph@codesourcery.com> [BZ #21314] * sysdeps/ieee754/dbl-64/s_log1p.c: Include <libc-diag.h>.

* RISC-V: Build InfastructurePalmer Dabbelt2018-01-2918-0/+433
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch lays out the top-level orginazition of the RISC-V port. It contains all the Implies files as well as various other fragments of build infastructure for the RISC-V port. This contains the only change to a shared file: config.h.in. RISC-V is a family of base ISAs with optional extensions. The base ISAs are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but this port currently only supports RV64I based systems. Support for RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc port supports most of the currently-defined extensions: the A extension for atomics, the M extension for multiplication, the C extension for compressed instructions, and the F/D extensions for single/double precision IEEE floating-point. Most of these extensions are handled by GCC, but glibc defines various floating-point wrappers and emulation routines as well as some atomic wrappers. We support running glibc-based programs on Linux, the support for which lives in sysdeps/unix/sysv/linux/riscv. 2018-01-29 Palmer Dabbelt <palmer@sifive.com> * sysdeps/riscv/Implies: New file. * sysdeps/riscv/Makefile: Likewise. * sysdeps/riscv/configure: Likewise. * sysdeps/riscv/configure.ac: Likewise. * sysdeps/riscv/nptl/Makefile: Likewise. * sysdeps/riscv/preconfigure: Likewise. * sysdeps/riscv/rv64/Implies-after: Likewise. * sysdeps/riscv/rv64/rvd/Implies: Likewise. * sysdeps/riscv/rv64/rvf/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/Versions: Likewise. * sysdeps/unix/sysv/linux/riscv/configure: Likewise. * sysdeps/unix/sysv/linux/riscv/configure.ac: Likewise. * sysdeps/unix/sysv/linux/riscv/ldd-rewrite.sed: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Implies: Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Makefile: Likewise. * sysdeps/unix/sysv/linux/riscv/shlib-versions: Likewise.

| | | | | | | | | | | | | | | | timer_ptr2id and timer_id2ptr are used to convert between application-visible timer_t and struct timer_node *. timer_ptr2id was made to use void * instead of timer_t in 49b650430eb5 ('Update.') for no reason. It happens that on Linux timer_t is void *, so both that change and this commit are no-ops there, but not on systems where timer_t is not void *.

* 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>
