Hi Dounia,
The following file maybe helpful to you.
1. common/com/opcode_gen_core.h, opcode_gen_core.cxx.
To add a new operator, and the allowed data type(MTYPE) for the
operator. Please look into the following code:
1. opcode_gen_core.h : the enum OPERATOR type
2. opcode_gen_core.h: the enum OPCODE type
3. opcode_gen_core.cxx: the OPERATOR_info array.
After extending the above files, you may also need to:
1. Find out at which part/phase, this new operator will be generate.
And adding the code. If you could provide more information, other guys in
this list may give you detailed help.
2. For How to expand it to instructions. please refer to
be/cg/whirl2ops.cxx, and be/cg/YOURTARGET/expand.cxx .
Open64 have a rich support of assertion, so you are suggested to
adjust other files according to the assertion fail information after all
the above modifications.
Regards,
Kun Ling

Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
With Perforce, you get hassle-free workflows. Merge that actually works.
Faster operations. Version large binaries. Built-in WAN optimization and the
freedom to use Git, Perforce or both. Make the move to Perforce.
