I am new to gcc compiler backend. I am currently studying how to the .md file to have a understanding. The thing that I don't understand is: I understand the standard pattern like movsi and etc, but I can see some pattern like movsi_internal, movsi_internal_v850e and etc, my question is where in the spec can I find them ? and where are they define ? -- View this message in context: http://gcc.1065356.n5.nabble.com/GCC-internals-Instruction-Patterns-tp1191730.html Sent from the gcc - Help mailing list archive at Nabble.com.
