I have a huge function (450K preprocessed) which causes GCC 2.2.2 on the NeXT to use over 90 megabytes of swap space, even with optimization turned OFF. The function has a large (1000+ entries) dispatch table, implemented using the "&&label" and "goto *label_array[n]" extensions. I realize this function should take a lot of space to compile, but 90 megabytes seems excessive (the final executable, for example, is smaller than 120K). Is this a bug? -Mat -- /-----------------------------------------------------------------------\ | Mat Hostetter mjhostet@athena.mit.edu (NeXTMail OK) | | MIT NeXT Campus Consultant | | "0100011001001110010011110101001001000100" | \-----------------------------------------------------------------------/
