You could try reducing data seg size (ulimit -d) to something matching "RAM" size. GCC has two parameters to try to keep its memory usage "reasonable": http://gcc.gnu.org/onlinedocs/gcc-4.2.4/gcc/Optimize-Options.html 'ggc-min-expand' and 'ggc-min-heapsize'. ggc-min-expand ... If getrlimit is available, the notion of "RAM" is the smallest of actual RAM and RLIMIT_DATA ggc-min-heapsize The default is the smaller of RAM/8, RLIMIT_RSS, or a limit which tries to ensure that RLIMIT_DATA or RLIMIT_AS are not exceeded I don't know if Clang/LLVM has something similar or not. -- -- David (obr...@freebsd.org) _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
