(arch_tab): Add HX. (targ_has_sfr): Handle ARCH_HX. (targ_has_iclass): Handle ARCH_HX. (tc_coff_fix2rtype): Add return 0 to avoid warning. (tc_headers_hook): If the architecture was specified explicitly, use it when setting the flags. Set the extern variable coff_flags rather than headers->filehdr.f_flags, since the latter is set unconditionally in obj-coff.c. (i960_handle_align): Remove unused variable fixp. --- diff --git a/gas/ChangeLog b/gas/ChangeLog index 136ab33..0622d76 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,5 +1,16 @@ Mon Feb 5 16:29:11 1996 Ian Lance Taylor + * config/tc-i960.c (ARCH_HX): Define. + (arch_tab): Add HX. + (targ_has_sfr): Handle ARCH_HX. + (targ_has_iclass): Handle ARCH_HX. + (tc_coff_fix2rtype): Add return 0 to avoid warning. + (tc_headers_hook): If the architecture was specified explicitly, + use it when setting the flags.
