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. + + Signed-off-by :Nagaraju Mekala <nmekala@xilix.com> + Ajit Agarwal <ajitkum@xilinx.com> +Upstream-Status: Pending + +Signed-off-by: Mark Hatle <mark.hatle@amd.com> + +--- + gcc/config/microblaze/microblaze.cc | 3 --- + 1 file changed, 3 deletions(-) + +diff --git a/gcc/config/microblaze/microblaze.cc b/gcc/config/microblaze/microblaze.cc +index 907c0afa9b8..f75eaff4b49 100644 +--- a/gcc/config/microblaze/microblaze.cc ++++ b/gcc/config/microblaze/microblaze.cc +@@ -2469,9 +2469,6 @@ print_operand (FILE * file, rtx op, int letter) + { + val[0] = (INTVAL (op) & 0xffffffff00000000LL) >> 32; + val[1] = INTVAL (op) & 0x00000000ffffffffLL; +- if (val[0] == 0 && val[1] < 0) +- val[0] = -1; +- + } + fprintf (file, "0x%8.8lx", (letter == 'h') ? val[0] : val[1]); + } +-- +2.37.1 (Apple Git-137.1) + |
