This implements TCO in the XSLT compiler by requiring a human to manually
indicate when a recursive call is in tail position. This was somewhat
urgently needed to resolve stack exhaustion on large rate tables.
TAMER will do this properly by determining itself whether a call is in tail
position. Until then, this will serve as a test for this type of feature.
This checks explicitly for unresolved objects while sorting and provides an
explicit error for them. For example, this will catch externs that have no
concrete resolution.
This previously fell all the way through to the unreachable! block. The old
POC implementation was catching unresolved objects, albeit with a debug
error.
We want to be able to build a representation of the dependency graph so
we can easily inspect it.
We do not want to make GraphML by default. It is better to use a tool.
We use "petgraph-graphml".
This begins providing release notes for changes and provides scripts to
facilitate this:
- tools/mkrelease will update RELEASES.md and run some checks.
- build-aux/release-check is intended for use in pipelines (e.g. see
.gitlab-ci.yml) to verify that releases were done properly.
