malcolm: Wed Mar 28 17:23:54 CEST 2001 Update of /usr/src/master/nhc/src/tracer/hat In directory hinken:/tmp/cvs-serv11650 Modified Files: hat-check.c Log Message: Make arg of hat-check consistent with other hat programs. The main argument of hat-check should be a program name without a ".hat" extension, just like the other hat programs.

olaf: Tue Mar 27 13:22:17 CEST 2001 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv7089/src/compiler98 Modified Files: DbgId.hs DbgTrans.hs Log Message: Introduced new combinator conCons to make transformed string literals shorter. The new tracing code for literal strings is a bit smaller. It also shares all uses of the (:) in a string. To improve it further, we would need to be able to use the tranformed list type and the untransformed one together in a combinator.

Fixed transformation of default methods.

olaf: Mon Mar 26 18:27:22 CEST 2001 Update of /usr/src/master/nhc/src/prelude/PreludeDebug In directory hinken:/tmp/cvs-serv4381/src/prelude/PreludeDebug Modified Files: PreludeDebug.hs Log Message: Fixed transformation of default methods. A missing default method lead to a corrupted trace file and sometimes even a segmentation fault. The problem was that the call to `fatal' was not wrapped within an R. Furthermore the error message "No match in pattern." was rather misleading. Now transform default method like any other function definition. The error message which has been introduced by the renamer is transformed like a normal expression. Changed renamer so that this compiler introduced expression has no source positions. So the explicit call of error is visible in the trace, but the browser user cannot ask for the source position.

Tentative fix to allow nhc98 to build itself again.

malcolm: Mon Mar 26 13:23:49 CEST 2001 Update of /usr/src/master/nhc/src/prelude/IO In directory hinken:/tmp/cvs-serv3307 Modified Files: OpenFile.hs Log Message: Tentative fix to allow nhc98 to build itself again. We have been getting segfaults recently when nhc98 is built by itself. I think it is a problem with the newish implementation of openFile. The returned Addr was converted to a ForeignObj lazily - which probably meant that the ForeignObj was being finalised before it was actually placed into the program graph! This change puts the prim operation addrToForeignObj into the IO monad, to force immediate evaluation.
