patch applied (hat): Hat: achieve a 30-40% speed-up in running traced programs.

Sun Mar 25 10:34:56 PST 2001 malcolm * Hat: achieve a 30-40% speed-up in running traced programs. This improvement is mainly due to moving work from Haskell to C. We were already storing certain triples of trace information (file ptr, trustedness, hiddenness) as a C struct, but continuing to use trivial access/construction functions in Haskell. Here, we remove all uses of the triples to C, and use only higher-level calls in Haskell. As a biproduct, the change of type from data Trace to newtype Trace must be rippled through all of the standard .T.hi files.

patch applied (hat): Remove need for a different compiler for tracing.

Sun Mar 25 09:52:18 PST 2001 malcolm * Remove need for a different compiler for tracing. For a long time, we generated a second compiler called nhc98compT with only a few small differences from the ordinary compiler called nhc98comp. Some of the differences have now gone away, and the rest can either be incorporated directly into the ordinary compiler (where a pattern-match or test would only succeed for trace-transformed code anyway), or guarded by an extra test on the command-line flag -dbgtrans (where there might be a conflict with ordinary code).
