| | | | | I think the path to readable tests for survey.subx passes through white-box tests.

| | | | | | 'get-or-insert-stream' is now the more generic 'get-or-insert' that can handle tables of any value type. But callers have to be careful to cast values to the right type.

* new primitive: parse-array-of-intsKartik Agaram2019-05-2514-8/+355
| | | | | | | | | | Mostly for tests. For every new type we want to compare in a test, we're now going to start using some primitive that can parse its value from string. In this manner we can get syntax for literals in machine code. Open question: parsing aggregates of aggregates. Like an array of structs. This is the first time we allocate from the heap in standard library tests. So we now need to start initializing the heap in all our apps.

* support the new segment syntax in assort.subxKartik Agaram2019-05-172-51/+35
| | | | | | | | | | | Now all implemented phases of the SubX translator in SubX support the new syntax: ✓ hex.subx (no changes required) survey.subx (not yet started) ✓ pack.subx (fixed here) ✓ assort.subx ✓ dquotes.subx (has failing tests for other reasons)
* another phase that supports the new segment syntaxKartik Agaram2019-05-172-18/+18
| | | | | | | | | | Current state: ✓ hex.subx (no changes required) survey.subx ✓ pack.subx (fixed here) assort.subx ✓ dquotes.subx (has failing tests for other reasons)
* start of new syntax for segment headersKartik Agaram2019-05-172-26/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now SubX defines headers with the following syntax: ``` === ... ``` The `...` can be either a numeric address or a name. Numeric addresses are useful for tests where we want to check addresses of individual instructions. Names are useful in real programs where we want to add to a segment in many places. This approach has long seemed a mess. It's hard to explain, and there's a certain amount of historical evolution that led to it that should be irrelevant to comprehend the current state of the codebase. I started out assuming the first segment was always code, before adding the special names 'code' and 'data'. We pretend to support more than two segments but we don't really. To simplify the code and explanation we'll move to a new syntax: ``` === <name> <address> ``` Code will always belong in the special name 'code', but it no longer has to be first. We need to migrate both our SubX-in-SubX phases and the C++ version. The plan is to start from the top down and update bootstrapping phases that've already been built (see commit 5102 for the list of phases). This commit updates pack.subx. Current state: ✓ hex.subx (no changes required) survey.subx ✓ pack.subx (fixed here) assort.subx dquotes.subx

| | | | Test for the bugfix of commit 2f49a27504.
* 5180Kartik Agaram2019-05-1611-44/+25
| | | | | | | Clean up some old TODOs related to our pre-mmap limitations. Also caught another case of using the wrong comparison. When comparing addresses, one must always use unsigned rather than signed jump instructions.

* complete the skeleton of dquotes.subxKartik Agaram2019-05-1512-49/+210
| | | | | | | | | | | | | | | | Still some failing tests: - emit-string-literal-data doesn't ignore metadata when computing the length of literal strings - emit-string-literal-data doesn't handle escape sequences One issue doesn't have a failing test: - emit-metadata doesn't handle string literals containing '/' All these open issues involve a common design question: how to parse a 'word' that includes a string literal that may include spaces. For everything else I know words can't contain spaces and datums can't contain slashes. But for string literals things are tougher.
