kr.angelov	e8335806af	GuString is now an ordinary C string - it makes live easier. In addition PgfSymbolKS, PgfExprFun and PgfLiteralStr now keep their strings as embedded flexible arrays. The latest change gives us the same compactness as the old representation but it is a lot easier to use.	2013-10-04 12:04:39 +00:00

kr.angelov	426bc49a52	a major refactoring in the C and the Haskell runtimes. Note incompatible change in the PGF format!!! ... The following are the outcomes: - Predef.nonExist is fully supported by both the Haskell and the C runtimes - Predef.BIND is now an internal compiler defined token. For now it behaves just as usual for the Haskell runtime, i.e. it generates &+. However, the special treatment will let us to handle it properly in the C runtime. - This required a major change in the PGF format since both nonExist and BIND may appear inside 'pre' and this was not supported before.	2013-09-27 15:09:48 +00:00
