| Subject: [PATCH 23/54] [patch,microblaze]: Fix the calculation of high word in |
| a long long 6. .4-bit |
| |
| This patch will change the calculation of high word in a long long 64-bit. |
| Earlier to this patch the high word of long long word (0xF0000000ULL) is |
| coming to be 0xFFFFFFFF and low word is 0xF0000000. Instead the high word |
| should be 0x00000000 and the low word should be 0xF0000000. This patch |
| removes the condition of checking high word = 0 & low word < 0. |
| This check is not required for the correctness of calculating 32-bit high |
| and low words in a 64-bit long long. |
