Subject: Disable integer sanitization in gcIfManyNewRefs.
X-Git-Tag: android-x86-9.0-r1~335^2~2^2~6^2^2^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=2ea713530fc0ad9954586e41db8c7409d44282ff;p=android-x86%2Fframeworks-base.git

Disable integer sanitization in gcIfManyNewRefs.

Prevent gcIfManyNewRefs from emitting runtime errors on
integer sanitized builds by disabling unsigned integer overflow
sanitization.

Test: Compiles, device boots.
