malcolm: Tue Feb 13 15:26:55 CET 2001 Update of /usr/src/master/nhc/src/tracer/runtime In directory hinken:/tmp/cvs-serv19455/src/tracer/runtime Modified Files: browsercomms.c ident.c ident.h stacktrace.c Log Message: Change the format of Hat (tracing) info tables. * Struct IdEntry now contains a pointer to struct ModInfo, rather than a char* modname. * Likewise, struct SrcRef also points to a struct ModInfo, rather than a char* modname. * In struct ModInfo, the char* srcfile field is now the genuine filename - the .hs suffix is no longer stripped. * All info structures now have an extra FileOffset word on the end, initially zero, but filled in when the structure is archived to file. * At the beginning of a traced computation, all ModInfo and IdEntry info is evacuated eagerly to an archive file. Note: because we added an extra word to each struct, this is a BREAKING change for traced code. You cannot mix old and new traced modules.

Add a new faster implementation of input I/O.

malcolm: Tue Feb 13 15:12:19 CET 2001 Update of /usr/src/master/nhc/src/runtime/Kernel In directory hinken:/tmp/cvs-serv19388/src/runtime/Kernel Modified Files: builtin.c newbuiltin.c mutator.c Log Message: Add a new faster implementation of input I/O. * There is a new bytecode instruction HGETS, and a new primitive Builtin.hgets that uses it. * The compiler recognises a special symbol _hGetStr and generates the new bytecode HGETS for it. * IO.hGetContents uses the special symbol _hGetStr, and hence the new bytecode. We achieve a 1.5x to 3x speed-up for raw lazy input. Unless a real program is very heavily input-bound, this won't give a vast saving, but for instance nhc98 is now 2.5% faster at building itself. Note: because the bytecodes have changed, this commit is a BREAKING change. You cannot mix old compiled code with new compiled code.
