SDCC source changes:
* src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
convilong): modified to inform the pic16 port that builtin functions
are external
PIC16 PORT specific changes:
* src/pic16/device.c pic16_dump_equates() added,
processor registers declared internally by the port are emitted in
the translation as equates,
* src/pic16/gen.c: inline code is passed unprocessed to the
translation,
* (pic16_popGetLit2): fnuction modified to take second operand as
pCodeOp pointer and not as literal,
* (popRegFromIdx): prefixed with pic16_,
* (pic16_popCombine2): modified to receive already allocated pCode
operands,
* (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): added
* (genFunction): initializes local stack frame and pushes on stack
all the registers used by this function,
* (genEndFunction): restores all registers from stack and restores
stack frame,
* src/pic16/glue.c (pic16emitRegularMap): various changes and
improvements,
* (pic16glue): changed the program startup sequence,
* added new dbName code 'A' for functions placed in absolute section
* src/pic16/main.c: added function attribute _naked,
* added pragma 'code' to place a fnuction at an absolute address,
* added command line arguments --debug-ralloc and --pcode-verbose,
* (_pic16_finiliseOptions): options.all_callee_saves is set by default
* src/pic16/pcode.c (pic16_pBlockConvert2Absolute) added,

pCodeOp pointer,
* (pic16_printpBlock): modified to emit each function in a separate
section,
* (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
UPPER for immediate operands,
* src/pic16/pcodepeeph.c: added peephole support for the LFSR
instruction,
* src/pic16/peeph.def: all peepholes with movff are commented out,
because there is a problem in the pcode peep optimizer,
* src/pic16/ralloc.c: the register allocator can now reuse local
function symbols for another function. This saves register usage.
* src/pic16/ralloc.h: added flag isLocal in structure regs,
Added file src/pic16/NOTES with information about program writing on
the current port version.

PIC16 port related changes:
* device.c: removed pic16_finalMapping and pic16_finalMappingSize,
added variable stackPos,
* gen.c: genCall, assignResultValue: added support for
pushing/retrieving function parameters to/from stack,
genFunction,genEndFunction: setup stack frame for the
generated function,
genAddrOf: will be changed according to bug 863624
* added files genutils.c and genutils.h which contain gen*
debugged and optimised functions extracted from gen.c
* glue.c: added variable 'externs' which holds extern symbols,
pic16emitRegularMap: is modified to properly handle relocatable
symbols under the new scheme,
pic16createInterruptVect: is modified
pic16printPublics: is modified to emit 'global' assembler directives,
added pic16_printExterns to print extern symbols,
pic16glue: initializes stack/frame pointer in the beginning of
the assembly output. Temporary hack, will be corrected later,
because gplink yet does not support stack and SDCC does not
yet support a type of crt0.o object to create the final binary.
* Removed many lines that contain 8051 legacy code.
* The code is finally placed under a 'code' directive.
* Added port specific options.
* _process_pragma: simplified since now we do not need *special*
include file to define SFR registers. But a separate header
will be needed. This will be developed later.
* _pic16_parseOptions: added, parses port specific options:
--pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
--pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
--preplace-udata-with=
* _pic16_setDefaultOptions: modified to initialize section names,
but hack is temporarly out of order since it needs improvement.
* _pic16_genAssemblerPreamble: configuration words are emitted by
their address instead of their name. This part is incomplete and
supports only the 18Fxx2 devices. Other devices will emit an error
during assembly since they do not contain the same set of config
registers
* _pic16_genIVT: is modified,
* pcode.c: added definitions for some hardware registers that are needed
for stack support
* added flag is2LitOp and variable pci_magic in pCodeInstruction.
All PCI entries are updated. Now LFSR is supported.
* Removed pic16_pciTRIS is mentioned by mdubuc in source
* added pic16_newpCodeOpLit2 to support instructions with
two literal arguments
* pic16_pCode2str: corrected code that emits assembler instructions
with two literal operands and those that have an access bit modifier
* genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
this fixes a bug which caused some labels to be lost, when an
assembler directive was added, i.e. banksel,
* pic16_FixRegisterBanking: improved logic that causes the insertion
of bank switching,
* InlineFunction: functions that are called once, are not any more
inlined. This can be a port option in the future,
* pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
* ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
hold the corresponding uninitialized symbols,
* pic16_allocProcessorRegister: registers have explicit marked the
accessBank field,
* pic16_allocInternalRegister: registers are explicit marked as
not used,
* pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
processing list, so bit registers were lost,
*
* ralloc.h: added field 'accessBank' and original symbol operand
in register definition,
* removed the field isMapped from register definition,
** Several functions have been removed from various sources:
BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
