This patch series implements most of the changes made by P1815. It also
cleans up a few bugs found along the way that impacted tests I wrote.
The whole patch series was bootstrapped on x86_64-pc-linux-gnu and
aarch64-unknown-linux-gnu with no regressions.
Changes since v1:
- Merged in already approved patches
- Use decl_maybe_constant_var_p intead of TREE_CONSTANT
- Treat weakrefs as not TU-local
- Check TU-local entities imported from header units
- Don't treat class-scope statics always as definitions
- Add testcase for standard-library exposures
Nathaniel Shead (6):
c++/modules: Detect exposures of TU-local entities
c++/modules: Implement ignored TU-local exposures
c++/modules: Support anonymous namespaces in header units
c++/modules: Check linkage for exported declarations
c++/modules: Validate external linkage definitions in header units
[PR116401]
c++/modules: Add testcase for standard-library exposures [PR115126]
