+ comment at interrupts section
+
+ Stack is made permanent, there is no ability to disable stack usage.
+ * src/pic16/device.h,
+ * src/pic16/device.c: removed all references to USE_STACK macro,
+ * src/pic16/device.c (pic16_dump_section): when no elements in
+ rlist, free rlist before return,
+ * (pic16_dump_int_registers): NEW, internal registers are a new set
+ of general purpose registers reused by each function,
+ * (checkAddReg): returns 1 if registers is added to set,
+ * (pic16_groupRegistersInSection): when a registers is of type
+ PO_GPR_TEMP add it in pic16_int_regs and not in pic16_rel_udata,
+ * src/pic16/device.h: memRange and Assigned Memory are deleted,
+ SRCASECMP macro is moved here from device.c
+ * src/pic16/genarith.c (pic16_pCodeOpType): added cases for
+ PO_PCLATU, PO_PRODL, PO_PRODH,
+ * (pic16_pCodeOpType, genMinus,
+ changed compares to "a" register, with AOP_ACC,
+ * (pic16_genPlus): fixed some bugs and indented properly,
+ * (pic16_addSign): changed size to size+offset in the MOVWF
+ instruction,
+ * (pic16_genUMult8XLit_8): NEW, uses processor MULLW instruction to
+ multiply 8-bit operand by literal, result is 8-bit,
+ * (pic16_genUMult8X8_8): NEW, uses processor MULWF instruction to
+ multiply 2 8-bit operand, result is 8-bit,
+ * (pic16_genMult8X8_8): modified to call genUMult8X*_8 functions and not
+ genUMult8X*_16,
+ * src/pic16/gen.c: changed accUse to contain WREG only,
+ * (pic16_emitcomment): renamed to pic16_emitpcomment,
+ * (aopForSym): allocated dir register when IN_DIRSPACE(space) is,
+ true, do not use immediate addressing any more unless sym is a
+ pointer in codespace,
+ * (aopForRemat): do not use immediate addressing when symbol not in
+ codespace and when symbol's address is requested,
+ * (aopOp): for-loop in if(sym->accUse) is modified for the new
+ accUse size (= 1),
+ * (aopGet): added case for AOP_ACC and don't return "accumulator
+ bug" but WREG instead,
+ * (popGetTempReg): pushes contents of temporary register in stack,
+ * (popReleaseTempReg): pops contents of temporary register from
+ stack. Use popGetTempReg/popReleaseTempReg in aligned pairs,
+ * (pic16_popGet): separated case AOP_ACC to return register WREG
+ from processor registers, AOP_PCODE not checks if pcop is PO_DIR
+ or PO_IMMEDIATE and initializes their instance/offset appropriately,
+ * The whole issue with aopForSym,aopForRemat,popGet) is to minimize
+ the use of immediate pointers to certain cases only.
+
+ * (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): use pic16_popGet2p,
+ * (pic16_loadFromReturn, pic16_storeForReturn: NEW,
+ * (assignResultValue, genCall, genRet): modified to use the new
+ function return value scheme with WREG,PRODL,PRODH,FSR0L and FSR0,
+ genPcall is still broken,
+ * (genFunction): added code to create 'A' type pBlocks when
+ interrupt functions are generated, code not extensively tested yet,
+ ISRs push WREG,STATUS,BSR,PRODL,PRODH,FSR0L,FSR0H registers on stack,
+ * (genEndFunction): modified so ISRs pop stored registers from stack,
+ * (genMultOneByte): cleanup,
+ * (AccRsh): added flag andmask, to and result with appropriate mask,
+ * (genUnpackBits,genPackBits): fixed and can handle bit fields,
+ * (genDataPointerGet): fixed and reenabled its use,
+ * (genNearDataPointerGet): bugs fixed,
+ * (genDataPointerSet): bugs fixed,
+ * src/pic16/genutils.c: added functions pic16_DumpValue,pic16_DumpAop,
+ pic16_DumpSymbol, pic16_DumpOp,
+ * src/pic16/genutils.h: function prototypes for the above functions,
+ * src/pic16/glue.c: new flags initsfpnt, to initialize stack/frame
+ pointers,
+ * (pic16emitRegularMap): many many many improvements, but needs a
+ major cleanup,
+ * src/pic16/main.c: enable_stack in pic16_options is removed,
+ * (_pic16_parseOptions): removed command line options -penable-stack,
+ * (_process_pragma): emit stack symbol only when stack pragma is
+ processed,
+ * src/pic16/pcode.c: pic16_pc_fsr0 is removed, all operations are
+ redirected to FSR0L/FSR0H pair,
+ * (pic16_get_op, pic16_get_op2): modifications and improvements,
+ * (pic16_getRegFromInstruction, pic16_getRegFromInstruction2): added
+ cases PO_PRODL,PO_PRODH, pic16_getRegFromInstruction2 returns sane
+ for immediates,
+ * (insertBankSwitch): modified to handle cases like: (alfa + 1)
+ * (dumpPicOptype): NEW,
+ * src/pic16/pcode.h: added PO_PCLATU,PO_PRODL,PO_PRODH in enum,
+ * src/pic16/pcoderegs.c (pCodeRegMapLiveRangesInFlow): fixed bug
+ with movff instruction,
+ * src/pic16/ralloc.c: renamed typeRegWithIdx to pic16_typeRegWithIdx,
+ added pic16_int_regs, some packRegsFor* functions are commented out,
+ because produce errors,
+ * src/pic16/NOTES: minor modifications
