--- Comment #41 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-11-15 13:51:11 UTC --- I will also post a small patch to gcc-patches to allow darwin to automatically pass the required linker flags on the link spec in darwin.h... ndex: gcc/config/darwin.h =================================================================== --- gcc/config/darwin.h (revision 193503) +++ gcc/config/darwin.h (working copy) @@ -180,6 +180,8 @@ extern GTY(()) int darwin_ms_struct; %{L*} %(link_libgcc) %o %{fprofile-arcs|fprofile-generate*|coverage:-lgcov} \ %{fopenmp|ftree-parallelize-loops=*: \ %{static|static-libgcc|static-libstdc++|static-libgfortran: libgomp.a%s; : -lgomp } } \ + %{faddress-sanitizer: \ + %{static|static-libgcc|static-libstdc++|static-libgfortran: -framework CoreFoundation libasan.a%s; : -framework CoreFoundation -lasan } } \ %{fgnu-tm: \ %{static|static-libgcc|static-libstdc++|static-libgfortran: libitm.a%s; : -litm } } \ %{!nostdlib:%{!nodefaultlibs:\ It works fine for the dynamic linkage although we do seem to have an issue with the static libasan.a that will require a new PR to be opened... % gcc-fsf-4.8 -faddress-sanitizer -O1 -fno-omit-frame-pointer -static-libgcc -g -o use-after-free use-after-free.c Undefined symbols for architecture x86_64: "___cxa_throw", referenced from: __asan::InitializeAsanInterceptors() in libasan.a(asan_interceptors.o) (maybe you meant: __interception::real___cxa_throw, _wrap___cxa_throw ) ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status However I don't see that as a blocker to getting libsanitizer building on intel darwin.
