2024-02-29Fix PR libcc1/113977Tom Tromey1-2/+3
PR libcc1/113977 points out a case where a simple expression is rejected with a compiler error message. The bug here is that gdb does not inform the plugin of the correct alignment -- in fact, there is no way to do that. This patch adds a new method to allow the alignment to be set, and bumps the C front end protocol version. It also includes some updates to various comments in 'include', done here to simplify the merge to binutils-gdb. include * gcc-cp-interface.h (gcc_cp_fe_context_function): Update comment. * gcc-c-interface.h (enum gcc_c_api_version) <GCC_C_FE_VERSION_2>: New constant. (gcc_c_fe_context_function): Update comment. * gcc-c-fe.def (finish_record_with_alignment): New method. Update documentation. libcc1 PR libcc1/113977 * libcc1plugin.cc (plugin_finish_record_or_union): New function. (plugin_finish_record_or_union): Rewrite. (plugin_init): Use GCC_C_FE_VERSION_2. * libcc1.cc (c_vtable): Use GCC_C_FE_VERSION_2. (gcc_c_fe_context): Check for GCC_C_FE_VERSION_2.
2024-02-29Fix version negotiation in libcc1 pluginsTom Tromey1-2/+2
This fixes version negotiation in the libcc1 plugins. It's done in a simple way: the version number from the context object is now passed to base_gdb_plugin. The idea behind this is that when the client (gdb) requests version N, the plugin should respond with the newest version that it knows of that is backward compatible to N. That is, the connection can be upgraded. Note that the protocol does not change much, and no backward incompatibilities have ever been needed. The C plugin is also changed to advertise GCC_C_FE_VERSION_1. The version negotiation approach should of course be documented, but I did that in a subsequent patch, in order to only have one patch touching the 'include' directory and thus needing a merge to binutils-gdb. libcc1 * libcp1.cc (libcp1::libcp1): Use FE version number from context. * libcc1.cc (libcc1::libcc1): Use FE version number from context. (c_vtable): Use GCC_C_FE_VERSION_1.

2021-05-05libcc1: use variadic templates for callbacksTom Tromey1-7/+5
This patch completes the transition of libcc1 from the use of separate template functions for different arities to the use of variadic functions. This is how I had wanted it to work from the very beginning, and is possible now with C++11. I had thought that variadic callbacks required C++17, but it turns out that the approach taken here is basically equivalent to std::apply -- just a bit wordier. libcc1 * rpc.hh (argument_wrapper) <get>: Replace cast operator. (argument_wrapper<T *>) <get>: Likewise. (unmarshall): Add std::tuple overloads. (callback): Remove. (class invoker): New. * libcp1plugin.cc (plugin_init): Update. * libcp1.cc (libcp1::add_callbacks): Update. * libcc1plugin.cc (plugin_init): Update. * libcc1.cc (libcc1::add_callbacks): Update. * connection.cc (cc1_plugin::connection::do_wait): Update.
2021-05-05libcc1: share the GCC interface codeTom Tromey1-230/+12
Both the C and C++ side of the GDB plugin in libcc1 share a lot of code relating to the base GCC interface. It was all copy-and-pasted, but is essentially identical between the two. This is by design, as the base GCC API is intended to be shared. This patch merges the implementations into base_gdb_plugin, which was introduced earlier for this purpose. libcc1 * libcp1.cc (libcp1): Change parameters. Update. (libcp1_set_verbose, libcp1_set_arguments) (libcp1_set_triplet_regexp, libcp1_set_driver_filename) (libcp1_set_source_file, libcp1_set_print_callback, fork_exec) (libcp1_compile, libcp1_destroy, vtable): Remove. (libcp1::add_callbacks): New method, extracted from libcp1_compile. (gcc_c_fe_context): Update. * libcc1.cc (libcc1): Change parameters. Update. (libcc1_set_verbose, libcc1_set_arguments) (libcc1_set_triplet_regexp, libcc1_set_driver_filename) (libcc1_set_source_file, libcc1_set_print_callback, fork_exec) (libcc1_compile, libcc1_destroy, vtable): Remove. (libcc1::add_callbacks): New method, extracted from libcc1_compile. (gcc_c_fe_context): Update. * gdbctx.hh (base_gdb_plugin): Change parameters. (~base_gdb_plugin): New. <add_callbacks>: New virtual method. <plugin_name, fe_version, compiler_name, vtable>: New members. (get_self, do_set_verbose, do_set_arguments) (do_set_triplet_regexp, do_set_driver_filename) (do_set_arguments_v0, do_set_source_file, do_set_print_callback) (fork_exec, do_compile, do_compile_v0, do_destroy): New methods.
2021-05-05libcc1: share GDB plugin codeTom Tromey1-87/+18
The two GDB plugins in libcc1 share a fair amount of code. This was done by copy-and-paste, though in reality the underlying code is nearly identical. libcc1 * libcp1.cc (struct libcp1): Derive from base_gdb_plugin. Remove shared code. (class libcp1_connection): Remove. (rpc): Remove. (libcp1_set_verbose, libcp1_compile): Update. (cp_call_binding_oracle, cp_call_symbol_address) (cp_call_enter_scope, cp_call_leave_scope): Update. * libcc1.cc (struct libcc1): Derive from base_gdb_plugin. Remove shared code. (class libcc1_connection): Remove. (c_call_binding_oracle, c_call_symbol_address): Update. (rpc): Remove. (libcc1_set_verbose, libcc1_compile): Update. * gdbctx.hh: New file.
2021-05-05libcc1: unify compiler handlingTom Tromey1-147/+12
Both libcc1 plugins have nearly identical copies of code to find the underlying compiler. This seemed wasteful to me, so this patch unifies the copies. Two minor API changes were needed. First, the old code used a back-link from the compiler object to the plugin object to check the 'verbose' setting. This patch adds a 'verbose' setting directly to the compiler object instead. Second, the 'find' method implicitly knew which compiler base name ("gcc" or "g++") to use. This patch makes this a parameter that is passed in by the plugin. libcc1 * libcp1.cc (compiler, compiler_triplet_regexp) (compiler_driver_filename): Remove. (libcp1::libcp1): Update. (make_regexp, libcp1::compiler::find) (libcp1::compiler_triplet_regexp::find) (libcp1::compiler_driver_filename::find): Remove. (libcp1_set_verbose, libcp1_set_arguments) (libcp1_set_triplet_regexp, libcp1_set_driver_filename): Update. * libcc1.cc (compiler, compiler_triplet_regexp) (compiler_driver_filename): Remove. (libcc1::libcc1): Update. (make_regexp, libcc1::compiler::find) (libcc1::compiler_triplet_regexp::find) (libcc1::compiler_driver_filename::find): Remove. (libcc1_set_verbose, libcc1_set_arguments) (libcc1_set_triplet_regexp, libcc1_set_driver_filename): Update. * compiler.cc: New file. * compiler.hh: New file. * Makefile.in: Rebuild. * Makefile.am (libcc1_la_SOURCES): Add compiler.hh, compiler.cc.
2021-05-05libcc1: use unique_ptr moreTom Tromey1-19/+13
This changes libcc1 to use unique_ptr in a few more places, removing some manual memory management. libcc1 * libcp1.cc (struct libcp1) <connection, compilerp>: Use unique_ptr. (~libcp1): Remove. (libcp1_compile, libcp1_set_triplet_regexp) (libcp1_set_driver_filename): Update. * libcc1.cc (struct libcc1) <connection, compilerp>: Use unique_ptr. (~libcc1): Remove. (libcc1_set_triplet_regexp, libcc1_set_driver_filename) (libcc1_compile): Update.
2021-05-05libcc1: use variadic templates for "rpc"Tom Tromey1-77/+4
This changes libcc1 to use variadic templates for the "rpc" functions. This simplifies the code and removes some possibility for mistakes. libcc1 * libcp1.cc (rpc): Use variadic template. Remove overloads. * libcc1.cc (rpc): Use variadic template. Remove overloads.
2021-05-05libcc1: use "override"Tom Tromey1-3/+3
This changes libcc1 to use "override" where appropriate. libcc1 * libcp1.cc (class compiler_triplet_regexp) (class compiler_driver_filename, class libcp1_connection): Use "override". * libcc1.cc (class compiler_triplet_regexp) (class compiler_driver_filename, class libcc1_connection): Use "override".
2021-05-05libcc1: use templates to unmarshall enumsTom Tromey1-1/+2
Now that C++11 can be used in GCC, libcc1 can be changed to use templates and type traits to handle unmarshalling all kinds of enums. libcc1 * marshall.hh (cc1_plugin::unmarshall): Use type traits. * marshall-cp.hh (cc1_plugin::unmarshall): Remove overloads. * marshall-c.hh: Remove. * libcc1plugin.cc: Update includes. * libcc1.cc: Update includes.
