Move code to disable ASR to nat/ This patch moves the shared code present on gdb/linux-nat.c:linux_nat_create_inferior and gdb/gdbserver/linux-low.c:linux_create_inferior to nat/linux-personality.c. This code is responsible for disabling address space randomization based on user setting, and using <sys/personality.h> to do that. I decided to put the prototype of the maybe_disable_address_space_randomization on nat/linux-osdata.h because it seemed the best place to put it. I regression-tested this patch on Fedora 20 x86_64, and found no regressions. gdb/ChangeLog 2015-01-15 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add nat/linux-personality.h. (linux-personality.o): New rule. * common/common-defs.h: Include <stdint.h>. * config/aarch64/linux.mh (NATDEPFILES): Include linux-personality.o. * config/alpha/alpha-linux.mh (NATDEPFILES): Likewise. * config/arm/linux.mh (NATDEPFILES): Likewise. * config/i386/linux64.mh (NATDEPFILES): Likewise. * config/i386/linux.mh (NATDEPFILES): Likewise. * config/ia64/linux.mh (NATDEPFILES): Likewise. * config/m32r/linux.mh (NATDEPFILES): Likewise. * config/m68k/linux.mh (NATDEPFILES): Likewise. * config/mips/linux.mh (NATDEPFILES): Likewise. * config/pa/linux.mh (NATDEPFILES): Likewise. * config/powerpc/linux.mh (NATDEPFILES): Likewise. * config/powerpc/ppc64-linux.mh (NATDEPFILES): Likewise. * config/powerpc/spu-linux.mh (NATDEPFILES): Likewise. * config/s390/linux.mh (NATDEPFILES): Likewise. * config/sparc/linux64.mh (NATDEPFILES): Likewise. * config/sparc/linux.mh (NATDEPFILES): Likewise. * config/tilegx/linux.mh (NATDEPFILES): Likewise. * config/xtensa/linux.mh (NATDEPFILES): Likewise. * defs.h: Remove #include <stdint.h> (moved to common/common-defs.h). * linux-nat.c: Include nat/linux-personality.h. Remove #include <sys/personality.h>; do not define ADDR_NO_RANDOMIZE (moved to nat/linux-personality.c). (linux_nat_create_inferior): Remove code to disable address space randomization (moved to nat/linux-personality.c). Create cleanup to disable address space randomization. * nat/linux-personality.c: New file. * nat/linux-personality.h: Likewise. gdb/gdbserver/ChangeLog 2015-01-15 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): Add linux-personality.c. (linux-personality.o): New rule. * configure.srv (srv_linux_obj): Add linux-personality.o to the list of objects to be built. * linux-low.c: Include nat/linux-personality.h. (linux_create_inferior): Remove code to disable address space randomization (moved to ../nat/linux-personality.c). Create cleanup to disable address space randomization.
