2016-03-17PR c/70264: fix crash in compatible_locations_p with BUILTINS_LOCATIONDavid Malcolm4-0/+30
In r234088 my fix for PR c++/70105 didn't allow for the possibility that when comparing a pair of macro expansion histories that one of the macros in the history might not be located within a line-map, and PR c/70264 reports a crash due to encountering BUILTINS_LOCATION within the traversal. Fixed thusly.

2016-03-17Properly set flag_pie and flag_picH.J. Lu14-3/+125
We can't set flag_pie to the default when flag_pic == 0, which may be set by -fno-pic or -fno-PIC, since the default value of flag_pie is non-zero when GCC is configured with --enable-default-pie. We need to initialize flag_pic to -1 so that we can tell if -fpic, -fPIC, -fno-pic or -fno-PIC is used. Since Darwin defaults to PIC (__PIC__ == 2) and the PIC setting can't be changed, skip tests of default __PIC__ and __PIE__ setting for *-*-darwin* targets. gcc/ PR driver/70192 * opts.c (finish_options): Don't set flag_pie to the default if -fpic, -fPIC, -fno-pic or -fno-PIC is used.
