PIE_VER is expected # to be the version of this patch, PIE_GCC_VER the gcc version of # the patch, and PIE_CORE (obsoleted) the actual filename of the patch. # An example: # PIE_VER="8.7.6.5" # PIE_GCC_VER="3.4.0" # The resulting filename of this tarball will be: # gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2 # old syntax (do not define PIE_CORE anymore): # PIE_CORE="gcc-3.4.0-piepatches-v${PIE_VER}.tar.bz2" # # PP_VER # PP_GCC_VER # obsoleted: PP_FVER # These variables control patching in stack smashing protection # support.
