Subject: X86: Make shift instructions set some of the flags they're supposed to.
X-Git-Tag: m5_2.0_beta4~170
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=00d9036c6221ce619cc933305b814e4784b15afa;p=gem5.git

X86: Make shift instructions set some of the flags they're supposed to.
The flag mechanism for microops needs to be fleshd out a little more to allow
for custom flag calculation methods for certain microops. Shift is an example
where the rules for calculating OF and CF are unique.
