Organization: Massachusetts Institute of Technology Lines: 10 Just a follow-up on a thread from last week about the c compiler giving better optimization when compiling with the symbolic info flag (for the debugger) set, i.e. cc -c -g -O because more information was being supplied to the optimizer. I tried this with the Linpack and Livermore Loops benchmarks and observed no noticeable difference in u+s times (~0.5%). Hal Youngren guppy@henry.mit.edu
