| | | | | | Be more consistent that 'return' is the name of the instruction, and 'reply' just a synonym. Maybe I should take it out. It wouldn't affect the recipe/ingredient terminology while I teach..
* 2873 - fix a bug in converting conditional returnsKartik K. Agaram2016-04-271-70/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was an interaction between two transforms. The first turned: return-if ... into: jump-unless ..., 1:offset # skip next instruction return ... The second added an unconditional return at the end of the recipe if it didn't already exist (so that functions always end with a return). However, it was getting confused by the return instructions generated above, which look unconditional but sometimes get skipped. To fix this, conditional returns are now transformed into this: { break-unless ... return ... } Since the final instruction is now no longer a reply (but rather the '}' label), the second transform triggers and adds the unconditional return after it. This commit removes the final place marked 'BUG:' in the codebase yesterday (see commit 2870).

Layers 0-29 are now a complete rudimentary platform except for pointers and indirection.
