Re: gcc-6-branch test failures: g++ c-c++-common/asan/pr59063-2.c

This problem turned out to be because the objects in libasan.a of gcc-6-branch are built with -fPIC / -DPIC : if 'PIC' is defined, the code in asan_linux.c is assuming it has been dynamically loaded , and so does not allow libasan.so NOT to be the first required dynamic library. But adding '-lasa

DF mangling

Hi! The Itanium C++ ABI defines https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-builtin DF_ as the mangling for the bit IEEE binary float type, i.e. _Float. But the libiberty unwinders decode DF as fixed point type, see https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libiberty/cp-demangl
