2017-11-17Use rcrt1.o%s/grcrt1.o%s to relocate static PIEH.J. Lu1-2/+3
crt1.o is used to create dynamic and non-PIE static executables. Static PIE needs to link with rcrt1.o, instead of crt1.o, which is also used by musl libc and OpenBSD: https://gcc.gnu.org/ml/gcc/2015-06/msg00008.html to relocate static PIE at run-time. When -pg is used with -static-pie, grcrt1.o should be used. * config/gnu-user.h (GNU_USER_TARGET_STARTFILE_SPEC): Use rcrt1.o%s/grcrt1.o%s for -static-pie. From-SVN: r254890

2017-09-12Add -static-pie to GCC driver to create static PIEH.J. Lu1-7/+8
This patch adds -static-pie to GCC driver to create static PIE. A static position independent executable (PIE) is similar to static executable, but can be loaded at any address without a dynamic linker. All linker input files must be compiled with -fpie or -fPIE and linker must support --no-dynamic-linker to avoid linking with dynamic linker. "-z text" is also needed to prevent dynamic relocations in read-only segments. PR driver/81498 * common.opt (-static-pie): New alias. (shared): Negate static-pie. (-no-pie): Update help text.

2017-08-08PR driver/81523: Make -static override -pieH.J. Lu1-10/+24
-static and -pie together behave differently depending on whether GCC is configured with --enable-default-pie. On x86, "-static -pie" fails to create executable when --enable-default-pie isn't used, but creates a static executable when --enable-default-pie is used. This patch makes -static completely override -pie to create a static executable, regardless if --enable-default-pie is used to configure GCC. gcc/ PR driver/81523 * gcc.c (NO_PIE_SPEC): Delete.
