X-Git-Tag: basepoints/gcc-15~2288
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ce7f0df47e83b16c3d7bedfbd7966f01d7ce14b1;p=thirdparty%2Fgcc.git

gccrs: Add multiple tests for non root proc macro

Add multiple tests to prevent regressions on procedural macros errors
when one is declared outside of the crate's top level.

gcc/testsuite/ChangeLog:

	* rust/compile/proc_macro_attribute_non_root_function.rs: New test.
	* rust/compile/proc_macro_attribute_non_root_method.rs: New test.
	* rust/compile/proc_macro_attribute_non_root_module.rs: New test.
	* rust/compile/proc_macro_derive_non_root_function.rs: New test.
	* rust/compile/proc_macro_derive_non_root_method.rs: New test.
	* rust/compile/proc_macro_derive_non_root_module.rs: New test.
	* rust/compile/proc_macro_non_root_function.rs: New test.
	* rust/compile/proc_macro_non_root_method.rs: New test.
	* rust/compile/proc_macro_non_root_module.rs: New test.
