| Subject: [PATCH 28/54] [Patch, microblaze]: Correct the const high double |
| immediate value With this patch the loading of the DI mode immediate values |
| will be using REAL_VALUE_FROM_CONST_DOUBLE and REAL_VALUE_TO_TARGET_DOUBLE |
| functions, as CONST_DOUBLE_HIGH was returning the sign extension value even |
| of the unsigned long long constants also |
