+       Adding support for replacing ljmps with sjmps in jumptables
+       generated for switch statements. For now you need to set the
+       environment variable SDCC_SJMP_JUMPTABLE to enable this.
+       Now 4 algorithms for mcs51 jumptable generation are used:
+       ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
+       addresses loaded pc-relative for up to 112 cases and stack-pushing
+       target addresses loaded with offset from dptr for up to 256 cases.
+
+       * src/SDCCpeeph.c: added peephole conditional labelJTInRange
+       * src/mcs51/main.c: adapted constants for switch table generation
+       * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp
