Hi, Frankly, I am new in gcc development. I am working to implement programming model for distributed heterogeneous multicor system. Therefore, I need to write some #pragmas for my work. i.e, I need to invoke some particular code when there are some particular pattern in code. Could some one help me in this ...? Thanks in Advance!
