Class JSRSubroutineInfo
java.lang.Object
org.jikesrvm.compilers.baseline.JSRSubroutineInfo
final class JSRSubroutineInfo
- extends Object
This class is used during the building of reference/non-reference maps for
a method. Once a JSR/RET combination has been processed, other JSR may
be encountered that "jump" to the same subroutine. To calculate the maps
of the instruction that is immediately after the JSR, we need the maps at
the time of the JSR and the maps at the time of the RET.
