Changeset 38 for sources/src/sc_main.cc

Timestamp:

Jul 21, 2009, 3:28:11 PM (15 years ago)

Author:

Message:

Now detects if SystemCASS correctly handles runtime compilation with the current architecture. SystemCASS exits if runtime compilation is not supported. Use --nodynamiclink options if it exits. This may occur on 64 bits machines.

Usage help is more readable.

Code cleanup.

Add some code for the coming soon openMP feature.
