Subject: [Bug bootstrap/55289] darwin bootstrap fails due to missing libsanitizer/interception/mach_override directory and files

--- 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

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...

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.
