malcolm: Mon Mar 26 12:54:22 CEST 2001 Update of /usr/src/master/nhc/src/runtime/Builtin In directory hinken:/tmp/cvs-serv3208/src/runtime/Builtin Modified Files: cHIsEOF.c Log Message: hIsEOF does not have the same semantics as feof() in C. It appears that feof() does not truly test for end-of-file. The EOF marker must be set by a preceding read operation.

Hat: achieve a 30-40% speed-up in running traced programs.

malcolm: Sun Mar 25 20:34:56 CEST 2001 Update of /usr/src/master/nhc/src/tracer/runtime In directory hinken:/tmp/cvs-serv591/src/tracer/runtime Modified Files: fileformat.c fileformat.h getconstr.c getconstr.h io.c numeric.c vector.c Log Message: 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.

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).
