view c1x4hotspotsrc/HotSpotVM/src/com/sun/hotspot/c1x/HotSpotSignature.java @ 1439:d0c8d3a2a7e8
Modified domake script to use (and require) JRE7 environment variable for find the base of a JRE 7 installation. This script no also ensures that $JRE7/lib/amd64/jvm.cfg has the right value for '-client'.
Added c1x4hotspotsrc/hotspot/java as indirect launcher for $JRE7/bin/java that can be referenced from Eclipse launch configuration.
Copied .checkstyle_checks.xml from C1X project to c1x4hotspotsrc/HotSpotVM so that it can be used by HotSpotVM project without hard coded path to C1X in another Eclipse workspace.
Various other changes to reflect changes in CRI and C1X.
