Any way to output information on compiler-generated temporary variables in gcc?

[Michele Co <mc2zk@xxxxxxxxxxxx>]

Hello,

I'd like to gather/output information (size, offset, type -- if 
possible) of compiler-generated temporaries generated by gcc during 
compilation.  I have looked through the compiler options related to 
generating debug information but am unsure whether there is an option 
available that will already give me this information in some form.

Does anyone on this list know of a quick and relatively straightforward 
method for gathering and outputting this information if it hasn't 
already been done before?

Thanks!

Michele
