Re: State of gcc 2.95 use in Debian unstable
we very much appreciate your work on the gcc-2.95 debian package.
For us - and probably also for other users in the scientific
community - the "old" compiler version is still of great value.
We use gcc-2.95 to compile C/C++ code with very large mathematical
expressions generated by computer algebra software. This involves
very long (several thousand lines of code) functions to evaluate
multi-variable polynomial expression resulting from perturbation
theoretical solutions of physical problems.
We found that gcc-2.95 -Os produces object code of acceptable quality
within reasonable compilation times. gcc >=3 is less efficient w.r.t.
compilation time and memory consumption and in many cases even fails
to compile our codes due to the very long expressions. The C/C++ codes
generated from the computer algebra software are perhaps unusual but
Since what we are doing is not so unusual in theoretical physics we are
probably not alone with these kind problems. Please consider that even
if no other debian packages would depend on gcc-2.95 many users may
very much require it.
