+
+ * device/lib/printf_large.c: removed inline assembly for portability and
+ readability. Use printf_fast if speed or size are more important.
+ * src/pic16/gen.c: removed conditions around use of DEBUGpc
+ * src/pic16/genutils.h: added define for DEBUGpc for MSVC
+
+2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
+
+ * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
+ prevent compiler warning
+
+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>
+
+ * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
+ left is a bitfield, if yes, then don't optimize assignment. Perhaps
+ this can be optimized more?
+
+2005-03-10 Raphael Neider <rneider AT web.de>
+
+ * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
+ genNearPointerGet): (hopefully) fixed access to bitfields via
+ pointers (p->bitN = x; and x = p->bitN; failed)
