Dumping to C files seems to be unusable. Even while only dumping strings, symbols and conses this generates a 4.5Mb+ C source file which takes 15-30mn to compile into a 1.5+Mb object file. This on a 200Mhz R10000. We're going to do a dump to a binary file and be able to relocate pointers ourselves. After having looked at the problem it doesn't seem that difficult actually. I also have some ideas which could make it possible to have independant dump files for packages. But that fill be done in a second step. More information later. OG.
