| | | | | | | | | | | | | | | Fail early when writing to a fake file runs out of space. Makes debugging tests easier. Reads from files, on the other hand, are only buffering to a temporary stream, so it makes sense to silently stop when they run out of space. In the process I uncovered a testing bug in pack.subx: I was missing a trailing space in the expected result, but the test still passed because the space was getting truncated. Being principled about aborting on overflow by default will help avoid such issues. | ||||

| | | | | | | | write-stream-buffered isn't a clean abstraction. Ignoring the 'read' index of a stream is a hack. It's just saving us the trouble of a rewind-stream. So make it a helper of pack.subx rather than part of the standard library. | ||||

| | | | | | | | | | | Testing conversion of multiple lines in a data segment. Bugs fixed: 1. Stack issues in next-token helpers. 2. Needed to teach next-token to avoid newlines. 3. rewind-stream(line) before passing it to convert-code or convert-instruction. | ||||

| | | | | | | | | | | | | | | | | | Several bugs found after performing multiple loops through convert-data. This has been a general pattern: given how unsafe the x86 'language' is, the regular amount of testing with a single input doesn't really give sufficient confidence. Ever-present is the possibility that I forgot to pop something from the stack, either a spilled register or a local. Calling functions multiple times seems to help detect such bugs. So far I've been doing this extra level of testing implicitly when I build the next higher abstraction. But with `convert-data` the buck stopped, and much painful debugging ensued. One thing that would help is if `write` on streams didn't remain silent on overflow. But we actually need that sometimes, when streams are used as buffers. | ||||
