89c25e3f6c Added a type-class for retrieving the (AST) type of things 
This patch hides all the old typeOfExpression, typeOfName, typeOfVariable, etc, and unifies them into a single type-class with an "astTypeOf" function.  The type-class is currently named Typed, but that can easily be changed (it's only explicitly referred to in the Types module).  The patch is essentially the type-class with a giant find-and-replace on the other modules.

af7a15b4df Changed testTransformProtocolInput so that it does transform protocol inputs in ALT guards 2008-02-27 17:20:19 +00:00

5c7bb1296b Altered transformProtocolInput to only bother flattening inputs with more than one item 2008-02-27 17:01:19 +00:00

3ce0eaf452 Made the first adjustment to the Pass system, ready to introduce properties and a dependency graph. For now passes are still executed in list order 2008-02-16 10:19:14 +00:00

acd57d74de Changed the A.Structured type to be parameterised 
This patch is actually an amalgam of multiple (already large) patches.  Those patches conflicted (parameterised Structured vs. changes to usage checking and FlowGraph) and encountered a nasty bug in darcs 1 involving exponential time (see http://wiki.darcs.net/DarcsWiki/ConflictsFAQ for more details).  Reasoning that half an hour (of 100% CPU use) was too long to apply patches, I opted to re-record the parameterised Structured changes as this new large patch.  Here are the commit messages originally used for the patches (which, as mentioned, were already large patches):

A gigantic patch switching all the non-test modules over to using parameterised A.Structured
Changed the FlowGraph module again to handle any sort of Structured you want to pass to it (mainly for testing)
A further gigantic patch changing all the tests to work with the new parameterised Structured
Fixed a nasty bug involving functions being named incorrectly inside transformInputCase
Added a hand-written instance of Data for Structured that allows us to use ext1M properly
Fixed a few warnings in the code

e9dbfbab3c Added the input-case to case pass to the pass-list, and therefore removed all code dealing with input-case statements in the C and C++ backends (and corresponding tests) 2007-10-14 00:01:44 +00:00
