        * varasm.c: Include asan.h.
        (assemble_noswitch_variable): Grow size by asan_red_zone_size
        if decl is asan protected.
        (place_block_symbol): Likewise.
        (assemble_variable): If decl is asan protected, increase
        DECL_ALIGN if needed, and for decls emitted using
        assemble_variable_contents append padding zeros after it.
        * Makefile.in (varasm.o): Depend on asan.h.
        * asan.c: Include output.h.
        (asan_pp, asan_pp_initialized): New variables.
        (asan_pp_initialize, asan_pp_string): New functions.
        (asan_emit_stack_protection): Use asan_pp{,_initialized}
        instead of local pp{,_initialized} vars, use asan_pp_initialize
        and asan_pp_string helpers.
        (asan_needs_local_alias, asan_protect_global,
        asan_global_struct, asan_add_global): New functions.
        (asan_finish_file): Protect global vars that can be protected.
        * asan.h (asan_protect_global): New prototype.
        (asan_red_zone_size): New inline function.

This is OK.


Thanks.  Diego.
