GCC OPTIMIZER

GCC OPTIMIZER

[Lalit Seth]

Hi,

I am having a set of files in One of the Module.
In which one of the file does compiled if no optimizer is specified ie 
-O,-O1,-O2,-O3.

But keeps on compiling the same when optimizer is defined at this time CPU 
Utilization is 100%.
At end if have to stop it as i have given it 5 mins to do so :(.

What can be the reasons for the same. From where i can start tracing it. Any 
tool for the same.

Many Thanks

Hi Lalit,

What OS are you using?

What version of GCC are you using?

Can you isolate the problem...
1. Could you break up the translation unit to separate files, such that 
there is merely one routine per source file?
2. And make sure that the header files which are included are minimal?
3. Create a standalone source file -- a "toy routine" -- that exhibits the 
bad behavior?
4. Submit that compilable (with no optimizer flags) / non-compilable (with 
optimizer flag) toy routine to this forum?
5. Specify all the compiler flags you utilize.
6. Provide the result of "gcc -v" or "g++ -v".

Thanks,
--Eljay

I think the reason why nobdy answers is that nodboy knows really what you are 
talking about (or at least I do not know).
Maybe you could formulate your question a bit different ?
