Message-ID: <199710170223.WAA08204@tweedledumb.cygnus.com> (raw)
| If the .eh_frame section does not get paged into memory, then I think 10% is
| acceptable (remember that the in-memory penalty is essentially zero). For
| kernels or embedded code where there is no paging, the acceptable figure
| is smaller, and I suspect that folks would use -fno-exceptions no matter
| how small the penalty is (unless it is 2% or less).
Some of the GCC ports I've done, even 2% is unacceptable (when you only have
32k or whatever, it does become critical not to have extra overhead).
