Hello, when compiling jdk/jdk on Windows, (with VS2017 update level 15.8 and not disabling warnings as errors ) I came across this warning leading to build error : C:/jdk-just-clone/src/hotspot/share/runtime/flags/jvmFlagRangeList.cpp(341): error C2220: warning treated as error - no 'object' file generated C:/jdk-just-clone/src/hotspot/share/runtime/flags/jvmFlagRangeList.cpp(341): warning C4305: 'argument': truncation from 'const intx' to 'double' Would have been helpful to have a compiler flag set that really ***shows the code*** leading to the warning/error (because it comes from heavy macro expansion).
Do you know of such a flag? If so we certain would like to add it. /Erik
