From 655fc22f1bc7a16d9da6bd44c43e763bc27d0b8a Mon Sep 17 00:00:00 2001 From: Milica Lazarevic Date: Mon, 12 Sep 2022 14:26:17 +0200 Subject: [PATCH] disas/nanomips: Remove __cond methods from class MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit NMD class methods with the conditional_function type like NMD::ADDIU_32__cond, NMD::ADDIU_RS5__cond, etc. are removed from the NMD class. They're now declared global static functions. Therefore, typedef of the function pointer, conditional_function is defined outside of the class. Now that conditional_function type functions are not part of the NMD class we can't access them using the this pointer. Thus, the use of the this pointer has been deleted.
