2.1.85 --hide_all, --no_hide_all
This option enables you to control symbol visibility when building SVr4 shared objects.
Usage
Use --no_hide_all to force the compiler to use STV_DEFAULT visibility for all extern
variables and functions if they do not use __declspec(dll*) or
__attribute__((visibility("visibility_type"))). This also forces them to be
preemptible at runtime by a dynamic loader.
When building a System V or ARM Linux shared library, use --no_hide_all together
with --apcs /fpic.
Default
The default is --hide_all.
