This abstracts away the canonicalizer and solves the problem whereby
canonicalization was not being performed prior to recording whether a path
has been visited. This ensures that multiple relative paths to the same
file will be properly recognized as visited.
This will be entirely replaced in an upcoming commit. See that for
details. I don't feel like dealing with the conflicts for rearranging and
squashing these commits.
This also includes an implementation to visit paths only once. Note that it
does not yet canonicalize the path before visiting, so relative paths to the
same file can slip through, and relative paths to _different_ files could be
erroneously considered to have been visited.
This will be fixed in an upcoming commit.
This serves as a constructor for the time being, decoupling from POC. We
may do something better once we have a better idea of how the various
abstractions around this will evolve.
Replacing the existing macros with templates will allow us to now have
to deal with macros in the new compiler.
The `indexNameType` pattern needed to change to allow for variables. I
also had to remove the prefix for the `gentle-no` option of `rate`.
Create a "yield" and add backwards compatibility for the macro of the
same name. This is one of 2 macros that need to be replaced so we do not
have to worry about them with the new compiler.
Add a stub executable that will eventually become a full-featured TAME
compiler. The first implementation will only copy the source file to an
intermediary file that will be compiled by the XSLT compiler.
Add a new step to the build process that copies the `xml` file to an
`xmli` file. Eventually, the new compiler will create the `xmli` file
and the old compiler will convert it to an `amle` file during the
transition.
This is an awkward system that I'd like to remove at some point. It adds
complexity. For the meantime, overrides have been arbitrarily restricted to
a single override (no override-override). But it's needed being until we
rework maps and can handle the illusion of overrides using the template
system.
Benchmark performance for this method is still substantially slower. And
oddly, this nearly doubled the speed of the other two calls (granted, at
that speed, it doesn't matter).
This properly checks identifier types when resolving externs. It also
includes a bit of refactoring. Note that some of that refactoring was
already merged into master.
The old linker was missing some things, so there are template changes in
here as well.
An example of an error currently:
error: extern `__retry` of type `cgen[boolean; 1]` is incompatible with
type `cgen[boolean; 0]`
All of these refactoring commits to arrive at this one final change: the
ability to store the source location for externs so that we can report on
what package is expecting an identifier to be defined.
Phew. Goodnight.
This undoes work I did earlier today...but now we'll be able to support a
Source on an extern.
There is duplicate code between `BaseAsg::declare{,_extern}` that will be
resolved in an upcoming commit. Upcoming commits will also simplify
terminology and clean up methods on ObjectState.
There is some duplication here with `declare` that will be cleared up in a
following commit. Reintroducing this method is necessary so that Source can
be used to represent the source location of the extern itself; it's
currently None to indicate an extern in `declare`.
This is the first step in a more incremental refactoring that previous
commits to undo the optional Source in `ObjectState::ident`. This provides
an explicit transition to an extern, with the intent of requiring an initial
missing state. This will simplify logic on the ASG.
Note that the Source provided to this new method is not yet used. That too
will come in a following commit and will represent the source of the defined
extern rather than the concrete identifier.
This properly verifies extern types, and cleans up Asg's API a little so
that externs aren't handled much differently than other declarations.
With that said, after making src optional, I realized that we will indeed
want source information for externs themselves so we can direct the user to
what package is expecting that symbol (as the old linker does). So this
approach will not work, and I'll have to undo some of those changes.
Merge branch 'jira-7133'
* jira-7133:
[DEV-7133] Clearly show the cycles in the output
[DEV-7133] Check for cyclic dependencies
[DEV-7133] Remove dependency from "lv:function/lv:param"
[DEV-7133] Add AsgError::Cycle
This is essential to clarify what exactly the different object types
represent with the new generic abstractions. For example, we will have
expressions as an object type.
There's a lot here to make the object stored on the `Asg` generic. This
introduces `ObjectState` for state transitions and `ObjectData` for pure
data retrieval. This will allow not only for mocking, but will be useful to
enforce compile-time restrictions on the type of objects expected by the
linker vs. the compiler (e.g. the linker will not have expressions).
This commit intentionally leaves the corresponding tests in their original
location to prove that the functionality has not changed; they'll be moved
in a future commit.
This also leaves the names as "Object" to reduce the number the cognative
overhead of this commit. It will be renamed to something like "IdentObject"
in the near future to clarify the intent of the current object type and to
open the way for expressions and a type that marries both of them in the
future.
Once all of this is done, we'll finally be able to make changes to the
compatibility logic in state transitions to implement extern compatibility
checks during resolution.
DEV-7087
The next commit will generalize this further. This moves logic out of
BaseAsg so that we can implement more sophisticated transitions for
compatability checks.
The logic is still tested as part of BaseAsg; the next commit will change
that as it's generalized further.
