- Previous message (by thread): [PATCH v2] Use DIAG_IGNORE_NEEDS_COMMENT to silence -Wstringop-truncation
- Next message (by thread): [PATCH] ld: Hide symbols defined by HIDDEN/PROVIDE_HIDDEN
- Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
There should be no difference in output for symbols defined by HIDDEN
or PROVIDE_HIDDEN assignments whether they are explicitly marked as
hidden or not. This patch adds a new BFD function, bfd_link_hide_symbol,
to hide symbols defined by HIDDEN and PROVIDE_HIDDEN assignments.
Any comments?
H.J.
