2015-11-09Update libsanitizer obstack interceptorsAlan Modra14-11/+99
New obstack uses sensible types, size_t instead of int for length params. Since libsanitizer does not use prototypes from obstack.h to call the real functions, it's necessary to update the libsanitizer function declarations emitted by the INTERCEPTOR macro. * sanitizer_common/sanitizer_common_interceptors.inc: Update size params for _obstack_begin_1, _obstack_begin, _obstack_newchunk interceptors. * configure.ac: Substitute OBSTACK_DEFS. * asan/Makefile.am: Add OBSTACK_DEFS to DEFS. * tsan/Makefile.am: Likewise. * configure: Regenerate. * Makefile.in: Regenerate. * asan/Makefile.in: Regenerate. * interception/Makefile.in: Regenerate. * libbacktrace/Makefile.in: Regenerate. * lsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.in: Regenerate. * tsan/Makefile.in: Regenerate. * ubsan/Makefile.in: Regenerate.
