gcc.c (LINK_GCC_C_SEQUENCE_SPEC): New spec to override the gcc/c library sequence passed to the linker.
2002-04-03 David S. Miller <davem@redhat.com>
* gcc.c (LINK_GCC_C_SEQUENCE_SPEC): New spec to override the gcc/c
library sequence passed to the linker.
(LINK_COMMAND_SPEC): Use it.
* doc/tm.texi: Document it, and mention from LINK_COMMAND_SPEC as
a macro a target can use to avoid overriding LINK_COMMAND_SPEC.
* config/sparc/sparc.h (LINK_GCC_C_SEQUENCE_SPEC): Define.
