2024-12-13gccrs: implement the TuplePattern and use it for function patternsPhilip Herron5-14/+117
In order to handle the tuple pattern of: fn test ((x _) : (i32, i32)) -> i32 { x } we need to recognize that ABI wise this function still takes a tuple as the parameter to this function its just how we can address the "pattern" of the tuple changes. So reall if this was C it would look like: void test (struct tuple_type __prameter) { return __parameter.0 } The code here reuses our existing pattern code so that we generate these implicit bindings of the paramter with a field access so any time x is referenced it's really just emplacing __parameter.0 for the field access into the struct which is a tuple. Fixes Rust-GCC#2847 gcc/rust/ChangeLog: * backend/rust-compile-fnparam.cc (CompileFnParam::visit): compile tuple patterns (CompileSelfParam::compile): update return type (CompileFnParam::create_tmp_param_var): return Bvariable not tree to stop ICE * backend/rust-compile-fnparam.h: update prototype * backend/rust-compile-pattern.cc (CompilePatternBindings::visit): implement TuplePattern * backend/rust-compile-pattern.h: update prototype gcc/testsuite/ChangeLog: * rust/compile/issue-2847.rs: New test.

2024-12-10build: update bootstrap req to C++14Jason Merrill1-14/+13
We moved to a bootstrap requirement of C++11 in GCC 11, 8 years after support was stable in GCC 4.8. It is now 8 years since C++14 was the default mode in GCC 6 (and 9 years since support was complete in GCC 5), and we have a few bits of optional C++14 code in the compiler, so it seems a good time to update the bootstrap requirement again. The big benefit of the change is the greater constexpr power, but C++14 also added variable templates, generic lambdas, lambda init-capture, binary literals, and numeric literal digit separators. C++14 was feature-complete in GCC 5, and became the default in GCC 6. 5.4.0 bootstraps trunk correctly; trunk stage1 built with 5.3.0 breaks in eh_data_format_name due to PR69995. gcc/ChangeLog: * doc/install.texi (Prerequisites): Update to C++14. ChangeLog: * configure.ac: Update requirement to C++14. * configure: Regenerate.

2024-12-02gccrs: constant evaluation like these are coercion sitesPhilip Herron5-15/+50
The code here was wrongly assuming the decl type from the folding of the expression would be the type of the constant decl.

2024-11-27gccrs: improve handling of Self Type pathsPhilip Herron9-61/+287
TypePaths have special handling for Self where we can look at the current ctx for more acurate TypeAlias information if required. We cant do this for Impl contexts but not for Traits as we might as well fall back to the TypePathProbe. The other issue was the dyn type comming in because Foo::foo and Foo is a trait reference we represent this as a dyn type as the root resolved path but then find the associated impl block for this but we cannot do this when we have resolved to a Dyn because this is just a representation that we know we are talking about a trait not because we are actually working with a real Dyn type.
