The rust language requires the export_name attribute to change the name of a symbol within the assembly whilst keeping a different name at the language level. This is used multiple times within rust-for-linux. gcc/rust/ChangeLog: * backend/rust-compile-base.cc: Change the assembly name on functions with the export_name attribute. Do not mangle the name. * util/rust-attribute-values.h: Add export_name attribute value. * util/rust-attributes.cc: Add export_name attribute to builtin attribute list. gcc/testsuite/ChangeLog: * rust/compile/export_name.rs: New test.

gcc/rust/ChangeLog: * util/rust-attributes.cc (AttributeChecker::visit): Use const variable. Signed-off-by: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>

Fixes #4386
Add export_name attribute on functions and lower it to gimple. Does not perform validity check.
