We usually test components independently, this means we did not test for lang item declaration within external crate. This commit introduces a new test directory to test external crate boundary. gcc/testsuite/ChangeLog: * rust/minicore/extern_lang_items.rs: New test. * rust/minicore/extern_lang_items_core/lib.rs: New test. * rust/minicore/minicore.exp: New test. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
Macros are already emitted by the AST dump within metadata files, we no longer require a separate export pass from within the metadata exporter. gcc/rust/ChangeLog: * metadata/rust-export-metadata.cc (PublicInterface::gather_export_data): Do not emit macros separately anymore. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
Add a few crates from the linux kernel to make sure core crate interactions does not break in the future. gcc/testsuite/ChangeLog: * rust/minicore/build_error.rs: New test. * rust/minicore/build_error_core/lib.rs: New test. * rust/minicore/compiler_builtins.rs: New test. * rust/minicore/compiler_builtins_core/lib.rs: New test. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
Return the injected crate's node id. gcc/rust/ChangeLog: * ast/rust-ast.cc (Crate::inject_extern_crate): Return the injected crate's node id. * ast/rust-ast.h: Update the function's prototype. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
Kernel and core related tests as well as their core crate needs to be compiled with a matching rust edition. In order to enforce that we control the edition from the testsuite instead of relying on a per crate edition change. Moreover, the kernel and core 1.49 is meant to be compiled with rust edition 2018, using this edition will make things easier for us. gcc/testsuite/ChangeLog: * rust/minicore/minicore.exp: Enforce crate edition at test top level. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
Node streaming started from the root and did not walk through the different preludes within the forever stack. This enables a more complete representation of the forever stack. gcc/rust/ChangeLog: * resolve/rust-forever-stack.hxx: Stream extern and lang prelude nodes. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
This data structure is complex, when using the debug dump within a debugger we often need to know what is the current state and where new nodes will be pushed within the forever stack. gcc/rust/ChangeLog: * resolve/rust-forever-stack.hxx: Debug the forever stack cursor position. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>
We did not assign any node id to neither extern and lang prelude nodes and this was confusing and could lead to unexpected behaviors (duplicate ids). gcc/rust/ChangeLog: * resolve/rust-forever-stack.h: Assign a node id to extern and lang nodes.
