GIMPLE temporary variables

[Andrea Callia D'Iddio]

Hi all,

I'm writing a new compilation pass in gcc, and I'm working on GIMPLE
code. When gcc produce GIMPLE code, it creates new temporary
variables, in order to simplify expressions and statements. For
example, if source C file contains
a=a+b+19;
then GIMPLE code is
D.1295 = a + b;
a = D.1295 + 19;
how can I recognize temporary variables, such as D.1295?
Thanks for support! bye!!
