--use_definition_visibility
Enables the linker to use the visibility of the definition in preference to the visibility of a reference when combining symbols.
Usage
When the linker combines global symbols the visibility of the symbol is set with the
strictest visibility of the symbols being combined. Therefore, a symbol reference with
STV_HIDDEN visibility combined with a definition with
STV_DEFAULT visibility results in a definition with
STV_HIDDEN visibility.
For example, a symbol reference with STV_HIDDEN visibility combined with a
definition with STV_DEFAULT visibility results in a definition with
STV_DEFAULT visibility.
This can be useful when you want a reference to not match a Shared Library, but you want to export the definition.
This option is not ELF-compliant and is disabled by default. To create ELF-compliant images, you must use symbol references with the appropriate visibility.
