+
+ Large cummulative patch for pic16 port.
+ * device/lib/pic16/gstack.h: NEW, user can specify its own handler
+ to call when a stack overflow occurs,
+ * (malloc.h): added CVS Id tag,
+ * (pic18f{242,252,442,452}.h): added T0CONbits structure and
+ variable,
+ * added libc directory. The current version of LibC contains string
+ functions, ctype functions and macros and some functions of the
+ stdlib set (like malloc/free/atof/atoi etc...). All functions are to
+ be extensively tested in the future. Standard disclaimer here.
+ Library is not automatically build yet. But one can build it by
+ invoking 'make' inside the libc directory.
+ * added ADC library under libio. Preliminary version yet.
+
+ * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
+ * src/pic16/gen.c (aopForRemat): asmop size is filled by
+ aopForRemat() now and not by pic16_aopOp(),
+ * (pic16_popGetTempReg): removed warning messgae when allocating
+ temporary registers, its a buggy feature and will be removed,
+ * (pic16_popGet): set register instance field in AOP_CRY,
+ * (pic16_outBitC): fixed for results in size greater than 1,
+ * (genUminusFloat): fixed for pic16, ported code from mcs51,
+ * (pic16_storeForReturn): optimized return of 0,
+ * (genCmp): experimental code for new genCmp which uses PIC18's
+ special compare&skip instructions. Initial tests fail some times
+ with variables grater than 1 byte in size, so new code is disabled,
+ * (genUnpackBits, genPackBits): more optimizations in reading/writing,
+ a single bit,
+ * (genCast): began a fix to optimize the casting of a bit to another
+ bit, now assigning a bitfield to another bitfield will fail, sorry,
+ * src/pic16/main.c: disabled the use of lr-support feature,
+ * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
+ * added some function prototypes, added function _debugf prototype,
+ * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
+ bits with offset (case PO_GPR_BIT),
+ * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
+ command line,
+ * (isBankInstruction): modified to return 0 for no banking instruction,
+ and 1 for banking instruction,
+ * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
+ caused stop processing pCodes after a inline assembly block,
+ * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
+ * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
+ registers when it shouldn't,
+ * src/pic16/ralloc.c (allocReg): add preliminary support for
+ supporting a limited set of temporary registers,
