From d15fa248605ca5c44f042a80a670088a83fb33fe Mon Sep 17 00:00:00 2001 From: Sagar Ghuge Date: Wed, 24 Oct 2018 13:27:27 -0700 Subject: [PATCH] intel/compiler: Print hex representation along with floating point value MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit While encoding the immediate floating point values in instruction we use values upto precision 9, but while disassembling, we print precision to 6 places, which round up the value and gives wrong interpretation for encoded immediate constant. To avoid misinterpretation of encoded immediate values in instruction and disassembled output, print hex representation along with floating point value which can be used by assembler in future.
