Richard SmithandJon Ross-Perkins	1e7b7e53ae	C++ interop: support for default arguments. (#6108) ... The general strategy here is to force use of a thunk when we want to use default arguments, and have Clang generate uses of the default arguments on its side of the thunk. To support this, change the key type used in `clang_decls` from being just a `Decl*` to being a pair of `Decl*` and number of parameters in the case of function decls. Import distinct `SemIR::Function`s for each number of parameters that's used, and corresponding distinct thunks. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>	2025-09-24 01:07:59 +00:00
Boaz Brickner	b88b53e7e3	C++ interop: Add support for importing globals (#6005) ... This supports importing globals in the global scope and within namespaces, and support for class static data members. C++ Interop Demo: ```c++ // my_global.h extern int my_global; void inc_my_global(); ``` ```c++ // my_global.cpp #include "my_global.h" int my_global = 5; void inc_my_global() { ++my_global; } ``` ```carbon // main.carbon library "Main"; import Core library "io"; import Cpp library "my_global.h"; fn Run() -> i32 { Core.Print(Cpp.my_global); Cpp.inc_my_global(); Core.Print(Cpp.my_global); return 0; } ``` ```shell $ clang -c my_global.cpp $ bazel-bin/toolchain/carbon compile main.carbon $ bazel-bin/toolchain/carbon link my_global.o main.o --output=demo $ ./demo 5 6 ``` Part of #6006.	2025-09-08 08:34:55 +00:00
Richard Smith	c7886f4336	Ask Clang to mangle names, don't try to do it ourselves. (#5764) ... Fixes mangling for `extern "C"` functions, as well as some other uncommon cases like multi-version functions.	2025-07-02 23:25:52 +00:00
