Hi,
quick question, I'm doing arm crossbuilds, trying to find an errornous
patch with bisecting. With crossbuild, I am specifying build-jdk.
How current does the build-jdk have to be? If the build jdk does not
fit the source I am trying to build, would that be immediately obvious
or would I get strange errors? I am gauging whether to rebuild the
build jdk for every bisect point.
As far as I know, we expect the BUILD_JDK to be an exact match, but in
practice it probably works with something a bit older most of the time.
It depends on what differences there are between the current source and
the BUILD_JDK. I haven't tried using an out of date BUILD_JDK but I
would imagine the errors to be strange and unpredictable. In your case,
if you want to avoid strange surprises, letting the BUILD_JDK be rebuilt
automatically is preferred, but if the bisect range is small, maybe it's
worth chancing it to save build time.
