expand: Add prc macro expander and registration
Add containers and functions to the hir-map in order to register and
lookup all three kind of procedural macros.
Add a first draft for attribute procedural macro expansion. This
expander still lack proper error handling as well as polishing.
gcc/rust/ChangeLog:
* util/rust-hir-map.cc (Mappings::insert_bang_proc_macro):
Add a function to insert a new bang proc macro.
(Mappings::lookup_bang_proc_macro): Add a function to lookup a
bang procedural macro.
(Mappings::insert_derive_proc_macro): Add a function to insert a
derive procedural macro.
(Mappings::lookup_derive_proc_macro): Add a function to lookup a
derive procedural macro.
(Mappings::insert_attribute_proc_macro): Add a function to
insert an attribute procedural macro.
(Mappings::lookup_attribute_proc_macro): Add a function to
lookup an attribute procedural macro.
* util/rust-hir-map.h: Add function prototypes.
* expand/rust-expand-visitor.cc (ExpandVisitor::expand_outer_attribute):
Implement expansion of outer attributes.
(ExpandVisitor::expand_inner_attribute):
Add call for inner attribute expansion.
* expand/rust-expand-visitor.h:
Add new procedural macro expander attribute.
* expand/rust-proc-macro.cc (load_macros_array): Add a function
to load the proc macro array from a given shared object.
(load_macros): Add a function to retrieve procedural macro
vector from a given shared object.
(ProcMacroExpander::import_proc_macros): Add a function to load
procedural macros from a given extern crate name.
* expand/rust-proc-macro.h (RUST_PROC_MACRO_H): Add new
proc-macro file.
(class ProcMacroExpander): Add new ProcMacroExpander class.
* rust-session-manager.cc (Session::expansion): Create new macro
expander and feed it to the expand visitor.
* util/rust-attributes.cc: Add macro_export builtin attribute.
