#######################################
Enable no-exec stacks for more targets using the Linux kernel. 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.
