GCC vs. Open64

Hi All, I am looking for an open source compiler, such as GCC, Open64, Scale and SUIF, as the infrastructure of my research. Though I have read some of their documents, they are still complicate to me and it is difficult to decide which one is better. Can you please help me to compare these

[Autovect]dependencies of virtual defs/uses

Hi, I am reading the code of autovect branch and curious about how to deal with the dependencies of virtual defs/uses. In the function vect_analyze_scalar_cycles( ), I found the statement Skip virtual phi's. The data dependences that are associated with virtual defs/uses ( i.e., memory accesses)

Re: [Autovect]dependencies of virtual defs/uses

Thanks! In fact, I should ask how to deal with idiom (such as reduction, induction) recognition for virtual defs/uses. Jiahua 2007/2/12, Daniel Berlin [EMAIL PROTECTED]: On 2/12/07, Jiahua He [EMAIL PROTECTED] wrote: Hi, I am reading the code of autovect branch and curious about how
