The Darwin ABI uses a different section for string constants when
address sanitizing is enabled. This adds defintions of the asan-
specific sections and switches string constants to the correct
section.
It also makes the string constant symbols linker-visible when
asan is enabled, but not otherwise.
gcc/ChangeLog:
* config/darwin-sections.def (asan_string_section,
asan_globals_section, asan_liveness_section): New.
* config/darwin.cc (objc_method_decl): Use asan sections
when asan is enabled.
(darwin_encode_section_info): Alter string constant
linker visibility depending on asan.
(machopic_select_section): Use the asan sections when
asan is enabled.
gcc/testsuite/ChangeLog:
* gcc.dg/torture/darwin-cfstring-3.c: Adjust for amended
string labels.
* g++.dg/torture/darwin-cfstring-3.C: Likewise.
