gccrs: expand: Add derive proc macro draft
Add a first draft for derive proc macros based on the attribute expander
code. Convert the result back to a parsable entity and parse it.
The procedural macro expander was beginning to require almost all
functionalities already provided by the macro expander, hence the merge.
gcc/rust/ChangeLog:
* ast/rust-ast-collector.h: Update enum name to match
definition.
* expand/rust-expand-visitor.cc (ExpandVisitor::expand_derive):
Add call to expander.
(ExpandVisitor::expand_outer_attribute):
Change call to macro expander.
(ExpandVisitor::expand_inner_attribute): Likewise.
* expand/rust-expand-visitor.h: Remove const attribute to match
visitor declaration. Attach result to the AST. Add condition for
item erasure.
* expand/rust-proc-macro.h: Add token collector and expansion
call. Add lexers and parsers for each proc macro type and uses
them to parse macro output.
* expand/rust-macro-expand.h (struct MacroExpander): Add
functions.
* expand/rust-proc-macro.cc (ProcMacroExpander::import_proc_macros):
Moved from here...
* expand/rust-macro-expand.cc (MacroExpander::import_proc_macros):
... to here. Unify procedural macro parsing under one function.
Add a flag to determine whether it originate from a derive
macro.
(MacroExpander::parse_procmacro_output):
Parse macro output to statements. Store an error on parsing
failure.
* Make-lang.in: Add const_TokenPtr specific lexer.
* expand/rust-proc-macro-invoc-lexer.cc: New file.
* expand/rust-proc-macro-invoc-lexer.h: New file.
* rust-session-manager.cc (Session::expansion): Remove
ProcMacroExpander declaration.
* ast/rust-ast-fragment.cc (Fragment::Fragment): Add overwrite
flag.
(Fragment::should_overwrite): Add a getter to determine whether
the fragment shall overwrite it's parent or be appended after.
* ast/rust-ast-fragment.h: Add flag to declaration.
