Subject: X86: Add operand type information to the fnstcw and fldw instruction placeholders.
X-Git-Tag: m5_2.0_beta4~222
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=55ade789d34e541cc538c7c5a4f286a313cfd8ba;p=gem5.git

X86: Add operand type information to the fnstcw and fldw instruction placeholders.
These are the only floating point instructions that get used in my simple hello world test. These instructions are for setting up the floating point control register. Their not being implemented doesn't affect anything because floating point isn't used.
