# HG changeset patch # User "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> # Date 1309180500 -7200 # Node ID 9d62710aa7ce46782da2cc122477b5350ca7c82b # Parent bf2d0ee90afdc4878d5e398470833dc7caeb3bd6 cc/gcc: add option for linker hash style Add an option to specify the hash type that gcc will ask the linker to use. It is a provision for the upcoming 4.7, as no version currently supports it. Signed-off-by: "Yann E.
