A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION to TC_CONS_FIX_NEW via static variables. That's OK, but not best practice. tc-ppc.c goes further in implementing its own replacement for cons(), because the generic one doesn't allow relocation modifiers on constants. This patch fixes both of these warts. * gas/config/tc-alpha.h (TC_CONS_FIX_NEW): Add RELOC parameter. * gas/config/tc-arc.c (arc_cons_fix_new): Add reloc parameter. * gas/config/tc-arc.h (arc_cons_fix_new): Update prototype.
