2017-09-26Enable no-exec stacks for more targets using the Linux kernel.Joseph Myers12-0/+76
Building glibc for many different configurations and running the compilation parts of the testsuite runs into failures of the elf/check-execstack test for hppa and microblaze. Those configurations default to executable stacks in the Linux kernel because of VM_DATA_DEFAULT_FLAGS definitions including VM_EXEC (VM_DATA_DEFAULT_FLAGS being the default definition of VM_STACK_DEFAULT_FLAGS). This fails because those configurations are not generating .note.GNU-stack sections to indicate that programs do not need an executable stack. This patch fixes GCC to generate those sections on those architectures (when configured for a target using the Linux kernel), as it does on other architectures, together with adding that section to libgcc .S sources, with the same code as used on other architectures (or a variant using "#ifdef __linux__" instead of the usual "#if defined(__ELF__) && defined(__linux__)" for microblaze, as that configuration doesn't use elfos.h and so doesn't define __ELF__). This suffices to eliminate that glibc test failure. (For hppa, the compilation parts of the glibc testsuite still fail because of the separate elf/check-textrel failure.) gcc: * config/microblaze/linux.h (TARGET_ASM_FILE_END): Likewise. * config/pa/pa.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa-linux.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa.c (pa_hpux_file_end): Rename to pa_file_end.

2017-06-28Use ucontext_t not struct ucontext in linux-unwind.h files.Joseph Myers12-12/+27
Current glibc no longer gives the ucontext_t type the tag struct ucontext, to conform with POSIX namespace rules. This requires various linux-unwind.h files in libgcc, that were previously using struct ucontext, to be fixed to use ucontext_t instead. This is similar to the removal of the struct siginfo tag from siginfo_t some years ago. This patch changes those files to use ucontext_t instead. As the standard name that should be unconditionally safe, so this is not restricted to architectures supported by glibc, or conditioned on the glibc version.

2017-03-10rs6000: float128 on BE and 32-bitSegher Boessenkool4-13/+23
This fixes float128 on BE and on 32-bit. The configure tests need to use -mabi=altivec for 32-bit, since it is not the default there. That also enables the "vector" keyword, used by the tests. To do this it temporarily adds a few flags to the CFLAGS variable. It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test (the function name was missing in the function declaration). Regenerating config.in (via autoreconf) removed the duplicate definition of HAVE_SOLARIS_CRTS. Finally, this adds a "-mfloat128-hardware requires -m64" test to rs6000.c: all the current patterns need 64-bit registers. Maybe we'll want to add float128 hardware support to 32-bit some day, but certainly not today. * config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow -mfloat128-hardware without -m64. libgcc/ * configure.ac (test for libgcc_cv_powerpc_float128): Temporarily modify CFLAGS.
