compiler-libs.optcomp

Documentation:

• Internal_variable_names
• Linkage_name
• Compilation_unit
• Variable Variable.t is the equivalent of a non-persistent Ident.t in the Flambda tree. It wraps an Ident.t together with its source compilation_unit. As such, it is unique within a whole program, not just one compilation unit.
• Closure_element
• Closure_id CR-someday lwhite: "Closure_id" is quite a generic name. I wonder whether something like "Closure_label" would better capture that it is the label of a projection.
• Symbol A symbol identifies a constant provided by either:
• Backend_var Variables used in the backend, optionally equipped with "provenance" information, used for the emission of debugging information.
• Clambda_primitives
• Printclambda_primitives
• Clambda
• Printclambda
• Semantics_of_primitives Description of the semantics of primitives, to be used for optimization purposes.
• Convert_primitives
• Id_types
• Export_id
• Tag Tags on runtime boxed values.
• Mutable_variable
• Set_of_closures_id An identifier, unique across the whole program, that identifies a set of closures (viz. Set_of_closures).
• Set_of_closures_origin
• Closure_origin
• Var_within_closure An identifier, unique across the whole program, that identifies a particular variable within a particular closure. Only Project_var, and not Var, nodes are tagged with these identifiers.
• Static_exception An identifier that is used to label static exceptions. Its uniqueness properties are unspecified.
• Pass_wrapper
• Allocated_const Constants that are always allocated (possibly statically). Blocks are not included here since they are always encoded using Prim (Pmakeblock, ...).
• Parameter Parameter.t carries a unique Variable.t used as function parameter. It can also carry annotations about the usage of the variable.
• Projection Representation of projections from closures and blocks.
• Flambda Intermediate language used for tree-based analysis and optimization.
• Flambda_iterators
• Flambda_utils Utility functions for the Flambda intermediate language.
• Freshening Freshening of various identifiers.
• Effect_analysis Simple side effect analysis.
• Inlining_cost Measurement of the cost (including cost in space) of Flambda terms in the context of inlining.
• Simple_value_approx Simple approximations to the runtime results of computations. This pass is designed for speed rather than accuracy; the performance is important since it is used heavily during inlining.
• Export_info Exported information (that is to say, information written into a .cmx file) about a compilation unit.
• Export_info_for_pack Transformations on export information that are only used for the building of packs.
• Compilenv
• Closure
• Closure_middle_end
• Import_approx Create simple value approximations from the export information in .cmx files.
• Lift_code
• Closure_conversion_aux Environments and auxiliary structures used during closure conversion.
• Closure_conversion
• Initialize_symbol_to_let_symbol
• Lift_let_to_initialize_symbol
• Find_recursive_functions "Recursive functions" are those functions f that might call either:
• Invariant_params
• Inconstant_idents
• Alias_analysis
• Lift_constants The aim of this pass is to assign symbols to values known to be constant (in other words, whose values we know at compile time), with appropriate sharing of constants, and replace the occurrences of the constants with their corresponding symbols.
• Share_constants Share lifted constants that are eligible for sharing (e.g. not strings) and have equal definitions.
• Simplify_common const_*_expr expr v annot, where the expression expr is known to evaluate to the value v, attempt to produce a more simple expression together with its approximation and the benefit gained by replacing expr with this new expression. This simplification is only performed if expr is known to have no side effects. Otherwise, expr itself is returned, with an appropriate approximation but zero benefit.
• Remove_unused_arguments
• Remove_unused_closure_vars
• Remove_unused_program_constructs
• Simplify_boxed_integer_ops
• Simplify_primitives
• Inlining_stats_types
• Inlining_stats
• Inline_and_simplify_aux Environments and result structures used during inlining and simplification. (See inline_and_simplify.ml.)
• Remove_free_vars_equal_to_args Replace free variables in closures known to be equal to specialised arguments of such closures with those specialised arguments.
• Extract_projections Identify projections from variables used in function bodies (free variables or specialised args, for example, according to which_variables below). Projections from variables that are also used boxed are not returned.
• Augment_specialised_args Helper module for adding specialised arguments to sets of closures.
• Unbox_free_vars_of_closures When approximations of free variables of closures indicate that they are closures or blocks, rewrite projections from such blocks to new variables (which become free in the closures), with the defining expressions of the projections lifted out of the corresponding sets of closures.
• Unbox_specialised_args When approximations of specialised arguments indicate that they are closures or blocks, add more specialised arguments corresponding to the projections from such blocks (with definitions of such projections lifted out), such that the original specialised arguments may later be eliminated.
• Unbox_closures Turn free variables of closures into specialised arguments. The aim is to cause the closure to become closed.
• Inlining_transforms Source code transformations used during inlining.
• Inlining_decision See the Flambda manual chapter for an explanation in prose of the inlining decision procedure.
• Inline_and_simplify
• Ref_to_variables Transform let-bound references into variables.
• Flambda_invariants
• Traverse_for_exported_symbols
• Build_export_info Construct export information, for emission into .cmx files, from an Flambda program.
• Closure_offsets Assign numerical offsets, within closure blocks, for code pointers and environment entries.
• Un_anf
• Flambda_to_clambda
• Flambda_middle_end Translate Lambda code to Flambda code, optimize it, and produce Clambda.
• X86_proc Definitions shared between the 32 and 64 bit Intel backends.
• X86_dsl Helpers for Intel code generators
• X86_gas Emit assembly instructions for gas.
