Subject: Large code size?
Date: Wed, 24 Mar 1999 09:38:00 -0000 [thread overview]
Message-ID: <E10PrbT-0003Og-00@roboto.devolution.com> (raw)
I'm comparing code size of an application compiled with VC++ and with egcs,
1.1.1 and the VC++ binary is smaller than the egcs binary by an almost exact
factor of two. The code being compared is self-contained, i.e. it calls no
library routines internally, and is pretty hairy C++ template code.
The egcs version (compiled with egcs 1.1.1, -O2 -funroll-loops):
-rwxrwxr-x 1 hercules devel 1534443 Mar 25 1999 robotcom.so
The VC++ version (compiled with VC++ 5.0, /G5 /Ox /Ot /Og /Oi /Op /Ob2)
-r-xr-xr-x 1 hercules devel 654336 Mar 14 10:26 robotcom.dll
Any ideas why this might be? The same ratio is true for the main
application, which is 13 MB on Linux, and 6 MB on Windows. 7 MB
of difference makes a significant impact on performance, and our
application compares poorly to the Windows version. We'd like it
to compare favorably. :)
Your thoughts, O Gurus? :)
