Agda.Syntax.Treeless
Description
The treeless syntax is intended to be used as input for the compiler backends. It is more low-level than Internal syntax and is not used for type checking.
Some of the features of treeless syntax are: - case expressions instead of case trees - no instantiated datatypes / constructors

TUnreachable | Code which is unreachable. E.g. absurd branches or missing case defaults. Runtime behaviour of unreachable code is undefined, but preferably the program will exit with an error message. The compiler is free to assume that this code is unreachable and to remove it. |
TMeta String | Code which could not be obtained because of a hole in the program. This should throw a runtime error. The string gives some information about the meta variable that got compiled. |

coerceView :: TTerm -> (Bool, TTerm) Source #
Strip leading coercions and indicate whether there were some.
coerceAppView :: TTerm -> ((Bool, TTerm), [TTerm]) Source #
Expose the format coerce f args
.
We fuse coercions, even if interleaving with applications.
We assume that coercion is powerful enough to satisfy
coerce (coerce f a) b = coerce f a b
word64View :: TTerm -> Maybe Word64 Source #
negPlusKView :: TTerm -> Maybe (Integer, TTerm) Source #
tUnreachable :: TTerm Source #
filterUsed :: [ArgUsage] -> [a] -> [a] Source #
filterUsed used args
drops those args
which are labelled
ArgUnused
in list used
.
Specification:
filterUsed used args = [ a | (a, ArgUsed) <- zip args $ used ++ repeat ArgUsed ]
Examples:
filterUsed [] == id filterUsed (repeat ArgUsed) == id filterUsed (repeat ArgUnused) == const []
