Greetings, fellow kaffe drinkers. I am trying to make kaffe 1.0.7 run on the m68k, under AmigaOS 3.9. It is supposed to run, but doesn't, for a number of reasons. I guess the Amiga configuration has been left untested for some time. I am configuring/compiling/testing it in a Geek Gadgets environment, using gcc 2.95.2. I have already installed, built and tested gmp-4.1 successfully, so something works.
First question: I've managed to get the whole kaffe suite to compile and build by editing some Makefile's and the config.h file. The changes were necessary to repair some syntax errors in the m68k Makefiles and correct some processor options. But when I run the /test/regression tests, a few run without error, but most trap out with the error: "Failed assertion 'block->avail > 0'" For HelloWorldApp, the trap happens right after a request for a block of size 32776 bytes (the first request > 32768). The address of the block returned seems crazy, being in the middle of the range of already-allocated memory. Suffice it to say that there is no valid gc- block in the vicinity. I have the same build on an x86 Linux machine, and it runs fine. I can even compare the memory requests and identify the same request on the Linux side - it returns with a reasonable pointer and works. I have been trying to compare the behaviour of the two systems, but I don't understand the structure of the heap or the blocks that are allocated. As a test, I commented-out the "PREDEFINED_NO_OF_TILES" in gc-mem.c and rebuilt it. It then trapped out with the error: "Failed assertion 'currentjThread == lastThread'" It would seem likely that there is a 16-bit integer problem here somewhere. I have checked the gcc options and the code generated in likely places - all seem to use 32-bit arithmetic. Has anyone any insight, or is there some in-depth documentation available for this area of code (mem/gc-mem.c)? Second question: Just running HelloWorldApp generates about 26,000 memory allocation requests during execution. Is this extraordinary overhead normal? cheers tony wyatt _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
