- Subject: [PATCH][alias-improvements] Fix Ada bootstrap
The following fixes Ada bootstrap - we forget to create constraints for
the static chain incoming parameter for un-nested functions. Oops.
Boostrapped on x86_64-unknown-linux-gnu for Ada/C. I'm completely
testing it now and, as it is latent on the trunk also test and apply
it there.
Richard.
