Modified: java/src/org/apache/xalan/xsltc/compiler
AbsolutePathPattern.java
Log:
Updated the absolute location path's branch instruction to allow for long
code branches. This is a common problem with large stylesheets. Some code
fragments similar to:
IFEQ(target)
Must be replaced with:
IFNE(skip)
GOTO_W(target)
skip:
NOP
This allows for branches with large branch target offsets.
