[PATCH 8/9] gdb: move rust_language into rust-lang.h
Andrew Burgess
andrew.burgess@embecosm.com
Fri Nov 20 11:55:03 GMT 2020
Move the rust_language class declaration into the rust-lang.h header
file. This allows for the function implementations called directly in
rust-lang.c and rust-exp.y without the need for trampoline functions.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* rust-exp.y (rust_parse): Rename to...
(rust_language::parser): ...this.
* rust-lang.c (-rust_printstr): Rename to...
(rust_language::printstr): ...this.
(rust_value_print_inner): Delete declaration.
(val_print_struct): Rename to...
(rust_language::val_print_struct): ...this. Update calls to
member functions.
(rust_print_enum): Rename to...
(rust_language::print_enum): ...this. Update calls to member
functions.
(rust_value_print_inner): Rename to...
(rust_language::value_print_inner): ...this. Update calls to
member functions.
(exp_descriptor_rust): Rename to...
(rust_language::exp_descriptor_tab): ...this.
(class rust_language): Move to rust-lang.h.
(rust_language::language_arch_info): Implementation moved to here
from class declaration.
(rust_language::print_type): Likewise.
(rust_language::emitchar): Likewise.
(rust_language::is_string_type_p): Likewise.
* rust-lang.h: Add 'demangle.h', 'language.h', 'value.h', and
'c-lang.h' includes.
(rust_parse): Delete declaration.
(class rust_language): Class declaration moved here from
rust-lang.c.
