From e6baf0e0b6757082554b9fc217f1f036e9e4ee8f Mon Sep 17 00:00:00 2001 From: Toma Tabacu Date: Tue, 24 Feb 2015 15:25:09 +0000 Subject: MIPS: LLVMLinux: Fix a 'cast to type not present in union' error. Remove a cast to the 'mips16e_instruction' union inside an if condition and instead do an assignment to a local 'union mips16e_instruction' variable's 'full' member before the if statement and use this variable in the if condition. This is the error message reported by clang: arch/mips/kernel/branch.c:38:8: error: cast to union type from type 'unsigned short' not present in union if (((union mips16e_instruction)inst).ri.opcode ^ ~~~~ The changed code can be compiled successfully by both gcc and clang.
