Re: Getting DWARF codes from RTX

So, I need the equivalent dwarf code (in hex) for DW_OP_REG1, DW_OP_REG2 and DW_OP_REG3, so that a dwarf decoder can decode it correctly. 

It's not clear what you mean by the dwarf code for DW_OP_REG1, etc.
Encoding for DW_OP_REG1, etc., is described in the Dwarf Standard on page 166.
See http://dwarfstd.org.

If you are looking for translation between gcc register numbers
and the Dwarf register numbers, look in dwarf2out.c.  Search for DBX_REGISTER_NUMBER.
