# Compile Lucene Core code specially
|
|
# GCJ can do more inlining when it compiles .java files than .class
|
|
# files, but not all of Lucene's core .java files are yet compilable
|
|
# by GCJ. (In particular, GCJ has problems with anonymous ctors that
|
|
# throw exceptions used in the Span and Sort code.) So we compile
|
|
# those that GCJ accepts from .java files, and those that GCJ does not
|
|
# yet accept from .class files.
|
|
# NOTE: Change when http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15501 is fixed.
