I'm using djgpp verion 1.03. In examining the .S output from a C++
code file, I find an enormous number of (to my mind) useless jmps.
They jmp over '.align 2,144' statements and even setting optimization
on does nothing to get rid of them. Are they in fact optimized by the
assembler, in which case I wouldn't know the difference?
I got sidetracked onto this by trying to figure out why my ray tracer
was so slow compared to those of people using Borland's C++.
I would appreciate any pointers, including whether this is improved in
gcc 2.0 (if the problem exists at all, of course).
Thanks,
Pete
