as: Global
7.39 '.global SYMBOL', '.globl SYMBOL'
======================================
'.global' makes the symbol visible to 'ld'. If you define SYMBOL in
your partial program, its value is made available to other partial
programs that are linked with it. Otherwise, SYMBOL takes its
attributes from a symbol of the same name from another file linked into
the same program.
Both spellings ('.globl' and '.global') are accepted, for
compatibility with other assemblers.
On the HPPA, '.global' is not always enough to make it accessible to
other partial programs. You may need the HPPA-only '.EXPORT' directive
as well. HPPA Assembler Directives HPPA Directives.
