• Subject: Committed, gas: Change defaults for cris-*-linux-gnu*.

This change makes gas for cris-*-linux-gnu* default to notrequire special options like "--no-underscore" for normalprogram assembly, by making use of a cute gas config header-filewith seemingly no other practical use that defines a macro thattc-cris.c can look at and then decide what to make its defaults.I would have liked to also cut out the multi-object-formatsupport for cris-*-linux-gnu*, but that'd cause gas to emit anerror: "Fatal error: emulations not handled in thisconfiguration" for the option "--em=criself" which GCC passes,and which is the default for recent binutils.  You might thinkthat's overridable in md_longopts, but it isn't: adding a matchfor e.g. "em=criself" causes getopt_long to error out with anambiguous-options message.  Maybe we can get the "emulations nothandled" message under control of a target macro?  Still, nohurry; it'd cut down on the binutils executable sizes a bit butrequire me to make a few more tweaks to the binutils testsuites.gas:* configure.in: Add specific case for cris-*-linux-gnu* withem=linux.* configure: Regenerate.* config/tc-cris.c (DEFAULT_CRIS_AXIS_LINUX_GNU): New macro, TRUEif TE_LINUX defined, else FALSE.(bfd_boolean demand_register_prefix): Set default fromDEFAULT_CRIS_AXIS_LINUX_GNU.(symbols_have_leading_underscore): Similar.* config/tc-cris.h (LOCAL_LABELS_DOLLAR): Define to 1.Index: configure.in===================================================================RCS file: /cvs/src/src/gas/configure.in,vretrieving revision 1.133diff -p -c -r1.133 configure.in*** configure.in13 Jun 2003 13:17:57 -00001.133--- configure.in15 Jun 2003 22:44:47 -0000*************** changequote([,])dnl*** 208,213 ****--- 208,214 ----        avr-*-*)fmt=elf ;;+       cris-*-linux-gnu*)fmt=multi bfd_gas=yes em=linux ;;        cris-*-*)fmt=multi bfd_gas=yes ;;        d10v-*-*)fmt=elf ;;Index: config/tc-cris.c===================================================================RCS file: /cvs/src/src/gas/config/tc-cris.c,vretrieving revision 1.26diff -p -c -r1.26 tc-cris.c*** config/tc-cris.c23 Jan 2003 12:51:04 -00001.26--- config/tc-cris.c15 Jun 2003 22:49:56 -0000*************** static char *cris_insn_first_word_frag P*** 157,167 ****  /* Handle to the opcode hash table.  */  static struct hash_control *op_hash = NULL;  /* Whether we demand that registers have a `$' prefix.
