[Mesa-dev] [PATCH] intel/compiler: Print floating point values upto precision 8

[Sagar Ghuge]

avoid misinterpretation of encoded immediate values in instruction and
disassembled output.

While encoding the immediate floating point values in instruction we use
values upto precision 8, but while disassembling, we print precision to
6 places, which round up the value and gives wrong interpretation for
encoded immediate constant. Printing it upto precision 8 will help in
reassembling it again.
