We install +nativesdk-gcc into a relocatable location and this means that its +library locations can change. "Normal" sysroot support doesn't help +in this case since the values of paths like "libdir" change, not just +base root directory of the system. + +In order to handle this we do two things: + +a) Add %r into spec file markup which can be used for injected paths + such as SYSTEMLIBS_DIR (see gcc_multilib_setup()). +b) Add other paths which need relocation into a .gccrelocprefix section + which the relocation code will notice and adjust automatically. + +Upstream-Status: Inappropriate +RP 2015/7/28 + +Signed-off-by: Khem Raj <raj.khem@gmail.com> +--- + gcc/cppdefault.c | 50 +++++++++++++++++++++++++++++++++++------------- + gcc/cppdefault.h | 3 ++- + gcc/gcc.c | 20 +++++++++++++------ + 3 files changed, 53 insertions(+), 20 deletions(-) + +diff --git a/gcc/cppdefault.c b/gcc/cppdefault.c +index e2e187dedaf..2faba2b1d63 100644 +--- a/gcc/cppdefault.c ++++ b/gcc/cppdefault.c +@@ -35,6 +35,30 @@ + # undef CROSS_INCLUDE_DIR + #endif + ++static char GPLUSPLUS_INCLUDE_DIRVAR[4096] __attribute__ ((section (".gccrelocprefix"))) = GPLUSPLUS_INCLUDE_DIR;
