+
+2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>

+
+2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
+
+ * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
+ moved to level 0 and declared as static. Also they are explicit
+ placed in access bank. This was necessery because some times they
+ might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
+ * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
+ optimizations. Currently only compare to unsigned char is implemented,
+ * src/pic16/gen.c: added fReturnIdx array,
+ * (struct resolvedIfx) is moved to gen.h and made public,
+ * (struct _G): added sregsAlloc and sregsAllocSet fields,
+ * (aopForSym): added an optimization to directly store in stack of
+ the operand of a SEND iCode,
+ * (pic16_aopOp): don't return return registers as strings (AOP_STR)
+ but as registers instead (AOP_REG) using the fReturnIdx array,
+ * (pic16_freeAsmop): remove the freed register from the
+ _G.sregsAlloc field,
+ * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
+ a compare of 'WREG',
+ * (pic16_popGetTempRegCond): changed function prototype, now
+ function takes also a bitVector argument v which holds the current
+ set of registers that are allocated for stack access by aopForSym,
+ registers allocated in aopForSym for accessing stack symbols are not
+ any more part of the functions usedRegs field,
+ * (genCall): some times aopOp is called for a stack variable to be
+ send, aopForSym might perform the push, if this is true make sure
+ that genCall doesn't push the variable twice by testing _G.resDirect,
+ * (genFunction): changed testing for unspecified interrupt number
+ from 256 to INTNO_UNSPEC,
+ * modified selection scheme of frame pointer generation. Previously
+ if function did use local registers a frame pointer was generated,
+ now a frame pointer is generated only if function has arguments
+ (that need PLUSW2 register access), or has stack arguments, or the
+ compiler is not instructed to omit the frame pointer,
+ * (genEndFunction): before restoring local registers that were saved
+ in the function preamble, also restore the registers that *might*
+ have been allocated for stack access,
+ * (genRet): removed some old comments,
+ * (genCmp, the active (RN's) version): added a call to the
+ pic16_genCmp_special function to perform the compare with a more
+ robust and optimized way,
+ * (genInline): a feature has been added in inline code generation,
+ which allows a wildcard variable substitution when writing inline
+ assembly. Code is incomplete and experimental therefore undocumented,
+ * (genCast): changed order of aopOp for result and right to allow
+ aopForSym to directly load the result if possible,
+ * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
+ perform an optimized compare on some selected special occasions,
+ * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
+ * src/pic16/glue.c (pic16createInterrupVect): make sure we never
+ generate an IVT any more,
+ * src/pic16/main.c (pic16_optionsTable): added command line option
+ --optimize-cmp,
+ * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
+ macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
+ macros,
+ * src/pic16/NOTES: Raphael Neider added in list of active developers
+ * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
+ jumptable_end to prevent bug #,
+ * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
+ inCond and outCond fields,
+ * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
+ * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
+ turn off register spilling,
+ * (packRegsForOneUse): synced with other ports' versions although it
+ is not used currently,
+ * (pic16_packRegisters): added an optimization while reading
+ structure bitfields, some registers may be saved (malloc code is
+ decreased by 80 bytes)
+
+2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
+

+ Adding support for replacing ljmps with sjmps in jumptables
+ generated for switch statements. For now you need to set the

+ 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,

+ * (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,

+ selected.
+ * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
+ * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be

+ * src/pic16/gen.c (struct _G): added field useWreg, is set to 1 when

+
+ * src/pic16/device.c (pic16_dump_gsection,
+ * pic16_groupRegistersInSection): handle symbols declared to be in
+ access bank differently,
+ * src/pic16/gen.c (struct _G): added field resDirect,

+ temporary values,
+ * (pic16_sameRegs): fixed bug that allowed MOVFF to move between
+ same registers,
+ * (pic16_sameRegsOfs): NEW,
+ * (freeAsmop): if _G.resDirect is set then do not mark registers as
+ free because they were not allocated from temporary pool,
+ * pic16_popRegFromString): workaround to fix a problem with
+ allocating variables twice or never,
+ * (genGenPointerGet): using PRODL instead of FSR0H,
+ * (genGenPointerSet): using POSTDEC1 (that is a stack location)
+ instead of FSR0H,

+ * (genCast): around line 11844, use mov2f instead of directly
+ MOVFF'ing between operands to account for literal values,
+ * src/pic16/genutils.c: some new debug functions for gpsim have been
+ added,
+ * src/pic16/glue.c (pic16_printIvalType): fixed bug that initialized

+ * src/pic16/glue.c (pic16glue),
+ * src/pic16/pcode.c (pCode2str, genericPrint): don't print .file or
+ .line directives if not in debug mode, this suppresses assembler's
+ warnings for ignored directives
