I am very curious about the overhead incurred by compiling CLN without -fno-exceptions.
Here is some data. Compiled cln-1.1.13 on Linux/i386 once with CXX="g++ -fno-exceptions" and once with CXX="g++" (both with GCC 4.1.2), and performed two deterministic programs, measuring user time: g++ -fno-exceptions g++ ./exam 1.24 sec 1.35 sec ./pi 100000 > /dev/null 2.64 sec 2.64 sec As was to be expected, the program which spends most of its time in large bignum multiplications is not slowed down. But the program which constructs many numbers and performs many (quick) computations is slowed down. Is a slowdown of 9% significant? Bruno
