Estimated hours taken: 2.5 Some more changes to minimize the complexity of the intermodule dependencies. In particular, ensure that bytecode.m does not need to import llds.m. compiler/llds.m: compiler/builtin_ops.m: Move the definitions of the unary_op and binary_op types into a new module `builtin_ops'. These types are used by three of the different back-ends (bytecode, llds, and mlds) and therefore deserve to be in their own module. compiler/bytecode.m: Define a type `byte_reg_type' and use that instead of llds__reg_type. Delete the import of module llds. compiler/notes/compiler_design.html: Document the new module builtin_ops. compiler/rl_exprn.m: Add a comment explaining why we need to import llds (and builtin_ops). compiler/base_type_layout.m: compiler/bytecode.m: compiler/code_util.m: compiler/dense_switch.m: compiler/ite_gen.m: compiler/jumpopt.m: compiler/llds_out.m: compiler/lookup_switch.m: compiler/middle_rec.m: compiler/opt_debug.m: compiler/opt_util.m: compiler/rl_exprn.m: compiler/string_switch.m: compiler/tag_switch.m: compiler/transform_llds.m: compiler/unify_gen.m: compiler/value_number.m: compiler/vn_block.m: compiler/vn_cost.m: compiler/vn_flush.m: compiler/vn_type.m: compiler/vn_util.m: compiler/vn_verify.m: Add imports of module builtin_ops to lots of modules that imported llds.

|
|
% This module defines various types which enumerate the different builtin
|
|
% operators. Several of the different back-ends -- the bytecode back-end,
|
|
% the LLDS, and the MLDS -- all use the same set of builtin operators.
|
|
% These operators are defined here.
