From c915a581459aa0d513e084cd95bd893164413d8e Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Thu, 9 Jan 2014 19:13:39 +0100 Subject: re PR sanitizer/59136 (llvm-symbolizer shouldn't be started always) PR sanitizer/59136 libsanitizer/ * sanitizer_common/Makefile.am (AM_CXXFLAGS): If LIBBACKTRACE_SUPPORTED add -DSANITIZER_LIBBACKTRACE and -I/-include flags. * lsan/Makefile.am (liblsan_la_LIBADD): Add libsanitizer_libbacktrace.la if LIBBACKTRACE_SUPPORTED. * tsan/Makefile.am (libtsan_la_LIBADD): Likewise. * ubsan/Makefile.am (libubsan_la_LIBADD): Likewise. * asan/Makefile.am (libasan_la_LIBADD): Likewise. * Makefile.am (SUBDIRS): If LIBBACKTRACE_SUPPORTED add libbacktrace. * README.gcc: Document that also lsan and ubsan are maintained in compiler-rt upstream. * libbacktrace/Makefile.am: New file. * libbacktrace/backtrace-rename.h: New file. * libbacktrace/backtrace-supported.h.in: New file. * libbacktrace/bridge.cc: New file. * configure.ac: Add tests needed for libbacktrace build within libsanitizer. * sanitizer_common/Makefile.in: Regenerated. * lsan/Makefile.in: Regenerated. * tsan/Makefile.in: Regenerated. * ubsan/Makefile.in: Regenerated. * libbacktrace/Makefile.in: Generated. * config.h.in: Regenerated. * configure: Regenerated. * Makefile.in: Regenerated. * interception/Makefile.in: Regenerated. * asan/Makefile.in: Regenerated. * aclocal.m4: Regenerated. testsuite/ * c-c++-common/asan/strip-path-prefix-1.c: Allow also the filename:line instead of (modulename+offset) form with stripped initial / from the filename.
