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. (TC_CONS_FIX_NEW): Add RELOC parameter. * gas/config/tc-arm.c (cons_fix_new_arm): Similarly * gas/config/tc-arm.h (cons_fix_new_arm, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-cr16.c (cr16_cons_fix_new): Similarly. * gas/config/tc-cr16.h (cr16_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-crx.h (TC_CONS_FIX_NEW): Similarly. * gas/config/tc-m32c.c (m32c_cons_fix_new): Similarly. * gas/config/tc-m32c.h (m32c_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-mn10300.c (mn10300_cons_fix_new): Similarly. * gas/config/tc-mn10300.h (mn10300_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-ns32k.c (cons_fix_new_ns32k): Similarly. * gas/config/tc-ns32k.h (cons_fix_new_ns32k): Similarly. * gas/config/tc-pj.c (pj_cons_fix_new_pj): Similarly. * gas/config/tc-pj.h (pj_cons_fix_new_pj, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-rx.c (rx_cons_fix_new): Similarly. * gas/config/tc-rx.h (rx_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-sh.c (sh_cons_fix_new): Similarly. * gas/config/tc-sh.h (sh_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-tic54x.c (tic54x_cons_fix_new): Similarly. * gas/config/tc-tic54x.h (tic54x_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-tic6x.c (tic6x_cons_fix_new): Similarly. * gas/config/tc-tic6x.h (tic6x_cons_fix_new, TC_CONS_FIX_NEW): Similarly. * gas/config/tc-arc.c (arc_parse_cons_expression): Return reloc. * gas/config/tc-arc.h (arc_parse_cons_expression): Update proto. * gas/config/tc-avr.c (exp_mod_data): Make global.
