+       Z80 and MCS51 linkers complaint if a public symbol is defined
+       in more than one library module:
+
+       * as/mcs51/lklib.c
+       * link/z80/lklib.c
+       * as/mcs51/Makefile.in

+       A few small changes that speed up the peephole optimizer.

+       * src/SDCCpeeph.c

+
+       Try to make the peephole optimizer smarter by maintaining
+       an association between the assembly source code and the
+       iCodes that originated them. Put this information to use
+       with a new peephole rule condition "notVolatile" so that
+       the rules can be aggressive yet still safe.
+
+       * src/SDCCpeeph.c
+       * src/SDCCpeeph.h
+       * src/mcs51/gen.c
+       * src/mcs51/peeph.def

+
+       Fixed bug #741761
+
+       * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
+       * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
+       if the left or right operand symbols have the accuse flag set.

        Changed the type of the result of the ! (NOT) operator to char;
