Subject: Do more optimization in release builds and add /Qspectre flag
X-Git-Tag: 9.0.0-rc1~25
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=2e0fd6f78f4657d34b1a0cea5ffd904a4a0ddcae;p=pvdrivers%2Fwin%2Fxeniface.git

Do more optimization in release builds and add /Qspectre flag

Spectre mitigations apparently only work on optimized code.
