Hi,

compared to 4.1.2 the size increased by 50% and more. E.g. Qt 4.2.2
libQtGui.so.4.2.2.debug
- 4.2.0 97902763 bytes
- 4.1.2 62435403 bytes

We compile with -O2 -g. Is this a regression or just more (useful?)
information?

It's more information - whether it's useful depends.

Wow, more than 50%. Are there any docs to this change?

Figure out which source causes the increase and then attach the preprocessed
source and then we might be able to decide.

It could be that in 4.1.2, that we were not emitting enums and some other types
which should have been emitting.

------- Comment #4 from Woebbeking at web dot de  2007-03-12 16:46 -------
Created an attachment (id=13194)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13194&action=view)
preprocessed qcombobox.cpp

I added both versions (4.2.0 and 4.1.2). It's compiled with

-c -fno-exceptions -pipe -O2 -g -fvisibility=hidden -fvisibility-inlines-hidden
-fPIC
