Adding build-dev as well -----Original Message----- From: hotspot-dev [mailto:[email protected]] On Behalf Of Christian Tornqvist Sent: Tuesday, August 19, 2014 7:39 PM To: [email protected] Subject: RFR(S): 8027480 - Build Windows x64 fastdebug builds using /homeparams
Hi everyone, This change adds /homeparams (http://msdn.microsoft.com/en-us/library/6exwh0y6.aspx) to compiler flags when building fastdebug on Windows x64. This causes the compiler to generate code to spill the first 4 arguments to the stack (they're normally only passed in registers), which should make it easier to debug. I also changed the ProjectCreator to enable building with this using Visual Studio. The size of jvm.dll increases with about 3% (about 504k increase). Verified that it builds correctly using Visual Studio and JPRT, the generation of the spill code has been verified by comparing prologue code for several functions in the JVM with/without using /homeparams.
