patch applied (c2hs): Don' t use precedence on if, just expect one s/r conflict

patch applied (c2hs): Document the declaration grammar
by Duncan Coutts 23 Mar '07

Thu Mar 22 05:27:50 PDT 2007 Duncan Coutts <duncan.coutts(a)worc.ox.ac.uk> * Document the declaration grammar Many of the productions specify various sequences of type qualifiers, storage class specifiers, type names and struct/union/enum declaration specifiers. These are quite hard to specify consisely with an ordinary context free grammar so it's quite hard to follow. To make it easier to understand I've added an extended grammar syntax which allows sequences with constraints on the number of occurences of items in the sequence. This allows these grammars to be specified very concisely. So hopefully that makes it easier for people to follow. I certainly didn't understand the grammar until I re-specified it this way. Also updated a bunch of other misc docs. M ./c2hs/c/CParser.y -21 +142

patch applied (c2hs): Merge the Roskind declaration/declarator grammar
by Duncan Coutts 23 Mar '07

Thu Mar 22 04:44:11 PDT 2007 Duncan Coutts <duncan.coutts(a)worc.ox.ac.uk> * Merge the Roskind declaration/declarator grammar Replace all the non-terminals and productions involved in the C declaration and declarator grammar with ones based on those from James Roskind's classic C grammar. The main point is that it allows us to recognise identifiers and type-identifiers in all the right places. For example it allows us to correctly deal with cases where type identiers get re-declared as function parameters or local vars. M ./c2hs/c/CParser.y -132 +519
