--- Comment #8 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-11-13 14:39:00 UTC --- Iain, This brings up the sticky situation of having to modify the Makefile.am file in libsanitizer/interception to add mach_override/mach_override.c to the interception_files source list and the Makefile.am file in libsanitizer/asan to link in the resulting interception/mach_override/mach_override.o object code to libasan. Any ideas on how to do this in a target specific manner cleanly?
