-
-/* This module implements main driver of compilation process.
-
- The main scope of this file is to act as an interface in between
- tree based frontends and the backend.
-
- The front-end is supposed to use following functionality:
-
- - finalize_function
-
- This function is called once front-end has parsed whole body of function
- and it is certain that the function body nor the declaration will change.
-
- (There is one exception needed for implementing GCC extern inline
- function.)
-
- - varpool_finalize_decl
-
- This function has same behavior as the above but is used for static
- variables.
-
- - add_asm_node
-
- Insert new toplevel ASM statement
-
- - finalize_compilation_unit
-
- This function is called once (source level) compilation unit is finalized
- and it will no longer change.
-
- The symbol table is constructed starting from the trivially needed
- symbols finalized by the frontend. Functions are lowered into
- GIMPLE representation and callgraph/reference lists are constructed.
- Those are used to discover other necessary functions and variables.
-
- At the end the bodies of unreachable functions are removed.
-
- The function can be called multiple times when multiple source level
- compilation units are combined.
-
- - compile
-
- This passes control to the back-end. Optimizations are performed and
- final assembler is generated. This is done in the following way. Note
- that with link time optimization the process is split into three
- stages (compile time, linktime analysis and parallel linktime as
- indicated bellow).
-
- Compile time:
-
- 1) Inter-procedural optimization.
- (ipa_passes)
-
- This part is further split into:
-
- a) early optimizations. These are local passes executed in
- the topological order on the callgraph.
-
- The purpose of early optimizations is to optimize away simple
- things that may otherwise confuse IP analysis. Very simple
- propagation across the callgraph is done i.e. to discover
- functions without side effects and simple inlining is performed.
-
- b) early small interprocedural passes.
-
- Those are interprocedural passes executed only at compilation
- time. These include, for example, transactional memory lowering,
- unreachable code removal and other simple transformations.
-
- c) IP analysis stage. All interprocedural passes do their
- analysis.
-
- Interprocedural passes differ from small interprocedural
- passes by their ability to operate across whole program
- at linktime. Their analysis stage is performed early to
- both reduce linking times and linktime memory usage by
- not having to represent whole program in memory.
-
- d) LTO streaming. When doing LTO, everything important gets
- streamed into the object file.
-
- Compile time and or linktime analysis stage (WPA):
-
- At linktime units gets streamed back and symbol table is
- merged. Function bodies are not streamed in and not
- available.
- e) IP propagation stage. All IP passes execute their
- IP propagation. This is done based on the earlier analysis
- without having function bodies at hand.
- f) Ltrans streaming. When doing WHOPR LTO, the program
- is partitioned and streamed into multiple object files.
-
- Compile time and/or parallel linktime stage (ltrans)
-
- Each of the object files is streamed back and compiled
- separately. Now the function bodies becomes available
- again.
-
- 2) Virtual clone materialization
- (cgraph_materialize_clone)
-
- IP passes can produce copies of existing functions (such
- as versioned clones or inline clones) without actually
- manipulating their bodies by creating virtual clones in
- the callgraph. At this time the virtual clones are
- turned into real functions
- 3) IP transformation
-
- All IP passes transform function bodies based on earlier
- decision of the IP propagation.
-
- 4) late small IP passes
-
- Simple IP passes working within single program partition.
-
- 5) Expansion
- (expand_all_functions)
-
- At this stage functions that needs to be output into
- assembler are identified and compiled in topological order
- 6) Output of variables and aliases
- Now it is known what variable references was not optimized
- out and thus all variables are output to the file.
-
- Note that with -fno-toplevel-reorder passes 5 and 6
- are combined together in cgraph_output_in_order.
-
- Finally there are functions to manipulate the callgraph from
- backend.
- - cgraph_add_new_function is used to add backend produced
- functions introduced after the unit is finalized.
- The functions are enqueue for later processing and inserted
- into callgraph with cgraph_process_new_functions.
-
- - cgraph_function_versioning
-
- produces a copy of function into new one (a version)
- and apply simple transformations
