2014-02-27	Fix error to constructor pattern matching	Kathy Gray

2014-02-27	Load POWER binary into interpreter's memory	Gabriel Kerneis

2014-02-27	Partial fix for to_vec_inc/to_vec_dec	Gabriel Kerneis
	Lem's word library does some dark magic because of its assumption that words represent signed integers. Therefore, it is unreliable to truncate words, as well as to use the internal representation. boolListFrombitSeq seems safe for our purposes, though (provided the bitseq has been created with an infinite length from a positive integer).
2014-02-27	More flexible test execution	Gabriel Kerneis

2014-02-27	Merge branch 'interp_typed'	Kathy Gray
	Conflicts: src/lem_interp/interp.lem src/lem_interp/run_interp.ml
2014-02-26	Get interpreter working using types, no added functionality yet	Kathy Gray

2014-02-26	Debug and fix memory multi-bytes memory writes	Gabriel Kerneis

2014-02-26	Fix vector slicing	Gabriel Kerneis

2014-02-25	Sensible types for POWER registers	Gabriel Kerneis

2014-02-25	Manage annot	Kathy Gray

2014-02-25	First step of using type information in interpreter. Reading and writing ↵	Kathy Gray
	plain registers supported; memory reading and writing is broken.
2014-02-21	Add type annotations to lem grammar, including printing out the annotated ↵	Kathy Gray
	ast, and extending the interpreter to expect annotations. Annotations and locations are still not used by the interpreter.
2014-02-18	Add function's name for external tag, using register when a register	Kathy Gray

2014-02-18	Put a plaster on bug for finding memory reading/writing operations	Kathy Gray

2014-02-18	Remove spurious add infix	Gabriel Kerneis

2014-02-18	Report failing tests and return 1 in case of error	Gabriel Kerneis

2014-02-18	Improve interpreter pretty-printing	Gabriel Kerneis

2014-02-18	Adding explicit order to for loops	Kathy Gray

2014-02-16	A bit of cleanup, including checking for loops and overloading 0 and 1 to be ↵	Kathy Gray
	bits in patterns where detectable.
2014-02-15	Full type checker. No constraint checking in place.	Kathy Gray

2014-02-14	Attempt multi-byte memory read and write	Gabriel Kerneis
	Test seems to fail for some reason, probably endianess and off-by-one bugs all over the place. Needs debugging code to monitor memory updates and display bitvectors in a compact way.
2014-02-14	Write slice to memory	Gabriel Kerneis
	I'm not sure whether this is useful at all. It is currently a bit broken when subrange is not in the "correct" order. Presumably the typechecker should catch this? I'm not quite sure what the intended semantics should be. Probably the same bug occurs with register slices too.
2014-02-14	Fix infinite loop bug, and test1.sail type checking bug	Kathy Gray

2014-02-14	update syntax of vector slicing.	Kathy Gray

2014-02-14	Infinite loop in interpreter for register slice write	Gabriel Kerneis
	I believe the issue is on the Lem side, but I might be doing something wrong on the OCaml side too.
2014-02-14	Register slice write	Gabriel Kerneis

2014-02-13	Disable line which does not typecheck in test1	Gabriel Kerneis
	We need to fix that one, but I don't know if the bug is in test1 or in the type checker.
2014-02-13	Add definition of ignore to make tests executable	Gabriel Kerneis

2014-02-13	Index memory with big_ints in interpreter	Gabriel Kerneis
	Also add support for sliced reads. Still need to implement sliced writes, as well as multi-word memory writes.
2014-02-13	Missing default case for literal equality test	Gabriel Kerneis

2014-02-13	Display backtrace when interpreter fails	Gabriel Kerneis

2014-02-13	Implement equality for big_int literals	Gabriel Kerneis
	Lem does not infer instances for typeclasses, falling back to unsafe comparison which does not work for big_int in OCaml.
2014-02-12	More library functions for interpreter	Gabriel Kerneis
	There is now enough stuff to decode and execute a very basic Branch instruction (encoding everything as little-endian rather than big- endian among many other work-arounds).
2014-02-12	Fix endianess issues	Gabriel Kerneis

2014-02-12	Checking assignment to a variable	Kathy Gray

2014-02-12	Replace nat by natural in interpreter	Gabriel Kerneis

2014-02-12	Remove spurious declaration	Gabriel Kerneis

2014-02-12	Fix type errors in power.sail	Gabriel Kerneis

2014-02-12	Change nat to natural in ott	Kathy Gray
	Type checking now recurses through assign, but doesn’t do the proper checks yet
2014-02-11	struct/record type checking	Kathy Gray

2014-02-07	type checking switch/case expressions	Kathy Gray

2014-02-07	Most of the vector expression type checking	Kathy Gray

2014-02-07	Fix a few stupid bugs	Gabriel Kerneis

2014-02-07	Implement is_one	Gabriel Kerneis

2014-02-07	Report unimplemented function name	Gabriel Kerneis

2014-02-07	Correct variable-name bug that was throwing away type checking coercions and ↵	Kathy Gray
	type annotations
2014-02-07	more checking	Kathy Gray

2014-02-07	Use bit->bool coercion for power.sail	Gabriel Kerneis

2014-02-06	coerce bit to bool when not a literal bit. Note: this will only add a ↵	Kathy Gray
	conversion function for expressions of bit type, an explicit cast to bit would be needed to come from an enum or nat.
2014-02-06	coercians for bits to bools for literals	Kathy Gray
