[Simh] Compiler differences

[Mark Pizzolato]

My observations are that clang does indeed compile faster than gcc,
however that doesn’t say much about how fast the compiled results
actually run.

If you’re only compiling a single simulator (which most users are
probably interested in) the compile time difference isn’t enough
to worry about.

When changes to simulators are made, compiling with both gcc
and clang are used since these compilers tend to detect different
errors.

Subject: [Simh] Compiler differences

Has anyone done a comparison (benchmarks) between simh emulators compiled with g++ verses clang?
clang seems to me to run quite a bit faster than gcc, but I haven't run any actual comparisons between the two so it is completely subjective.
A full 'make' seems to build faster with clang than gcc.
Just curious. I recently noticed bthe clang stuff in the makefile, so I thought I'd try it out.
