* genattrtab.c (expand_units): For large nr opclasses, expand function_units_used with ORX to prevent blowups. Tag with FFS. (num_unit_opclasses): New variable. (gen_unit): Update it. (enum operator): Add ORX_OP. (operate_exp): Treat ORX as or, except don't expand across an if. Reuse number rtx's after operating on them. (check_attr_value): Accept IOR, AND, & FFS. (write_test_expr): Transmute `in_comparison' to `flags'. Allow for attribute value caching. Handle CONST_STRING, IF_THEN_ELSE. (write_expr_attr_cache, write_toplevel_expr): New functions. (write_attr_get): Handle FFS-tagged expressions. (make_canonical): Don't expand const attributes. (convert_const_symbol_ref): Dike out. (evaluate_eq_attr): Handle SYMBOL_REF. (main): Don't emit get_attr_foo for const attributes. * alpha.c (override_options): Reinstate PROCESSOR_EV6. (alpha_adjust_cost): Add EV6 tuning; streamline EV5 tests. * alpha.h (REGISTER_MOVE_COST): Increase ftoi/itof cost slightly. * alpha.md: Redo all of the scheduling, adding EV6 support, and combining function units where possible. (attr "type"): Split loads, stores, cmov into int/fp. Combine multiplies and divides. Add EV6 sqrt, ftoi, itof. (attr "opsize"): New attribute. (sqrtsf2-1, sqrtdf2-1): Provide proper TP_INSN patterns. (movsf2-[12], movdf2-[12]): Provide CIX varients; don't allow CIX to control register allocation. (movsi2-1, movdi2-1): Likewise.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
