Shawn,
I've always considered the fact that gcc has such broad cross platform
support to be a bigger advantage. The fact that you can cross-compile to
so many processors, has enabled it to be the choice for embedded work.
I've heard about objective-c for such a long time, I think it was on the
first "Next" box I used...
But is there a significant advantage to the extentions, and/or are those
extentions widely used? It seems fairly insignificant for the most part.
I've heard of some objective-c work being done at Apple, but that wouldn't
matter as Apple has not shared much of their sources to date, AFAIK.
Most all of the compilers these days support the ansi c++ spec, but I
haven't followed this for a while so not up on the differences between
objective-c and the ansi c++ spec.
What do you consider to be the ones that would be attractive for
SunStudio? The tools folks are listening and trying to keep their finger
on the pulse of the community, so please let them know. They do attend and
present stuff at the SVOSUG, and next month will be doing a short presie
on a new tool which here is a blurb of...sounds interesting...
ATS - Automatic Tuning and Troubleshooting System
ATS is a binary reoptimization and recompilation tool that can be used
for tuning and troubleshooting applications. ATS works by rebuilding the
compiled PEC (Portable Executable Code) binary - the original source
code is not required.
Examples of what can be achieved using ATS are:
* Find the compiler options that give the best performance
* Find the object file and the optimization flag that
is causing a runtime problem (+++)
* Rebuild the application using new compiler options
Tom Kirkley will be presenting, I don't know if he follows this list or
not.
