Hi All,
      What will be the performance problems/constraints
in translating fortran programs to C and then
compiling it using a C compiler. Consider that the
translator does a fairly good job.
      I referred to a similar question in comp.compilers
earlier with subject
"Pros and cons of high-level intermediate languages"
can someone show me other disadvantages when
translating a language like fortran 90 to C especially
with respect to Performance.
        We intended to use this compiler in a high
performance computing environment.

[I'd think it depends a lot on the C compiler and how well the
translator passes through the Fortran semantics into the C program,
particularly procedure argument aliasing. -John]
