------- Comment #18 from jv244 at cam dot ac dot uk 2009-05-17 05:11 ------- the patch posted here: http://gcc.gnu.org/ml/fortran/2009-05/msg00244.html allows cp2k in its single source file form, 640klines as made available in PR40005, to compile with -fwhole-file (using the ulimit -s unlimited trick). Even the 3Gb memory usage seems reasonable. What about turning this option on by default now ? The warnings its generates are generally useful, and there is the potential gain in performance.
