I use the HP cc ` `I killed it after 2 hours. The standard cc compiler compiles it in 1 `minute. ` The problem appears to be the use of alloca(). I used the emacs alloca.c version. This causes considerable thrashing when compiling large programs with -O. For example: c-parse.tab.c compiled in 7 hours rather that the normal 1 minute. Solution: forget the -O flag on the stage1/stage2 compilations. I then do the compilation again with -O but starting with the just generated gcc (I want to make sure that gcc compiles itself correctly with -O, and I want to have an optimized compiler). Thanks all who responded. -- Piet van Oostrum, Dept of Computer Science, University of Utrecht Padualaan 14, P.O. Box 80.089, 3508 TB Utrecht, The Netherlands.
