+2005-01-22 Daniel Winkler <post AT danielwinkler.de>
+

+2005-01-22 Raphael Neider <rneider AT web.de>

+2005-01-19 Raphael Neider <rneider AT web.de>
+
+ * src/SDCCglobl.h: ensure that PATH_MAX >= 2048 to guarantee
+ cmdLine buffers (used when calling sdcpp...) are large enough

+ used in MinGW...)
+ * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
+ * (genUminus): rewritten to for efficiency
+ * (genNearPointer[GS]et): enforce reloading of FSR0 (was still

+ copy the third byte from the int -- now assumes 0x80 (data memory)
+ * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
+ operands (genAddLit expects the iCode's operands to swapped as
+ well), fixed leftover bytes (crashed for short left operands)

+ PIC14 emitSKPNCs
+ * (pic16_genMinus): fixed to cope with differently sized operands

+
+ * device/lib/pic16/libc/stdlib/x_ftoa.c: it defines x_ftoa function
+ which converts a float number to its ASCII representation

+ functions to convert the fractional and integer part of a float to ASCII,
+ * device/lib/pic16/libc/stdlib/(calloc.c,free.c, malloc.c,
+ realloc.c): added _MALLOC_SPEC to explicit place variables in data
+ ram
+ * device/include/asm/pic16/features.h: added _CODE, _DATA, _AUTOMEM,
+ _STATMEM macros,
+ * device/include/pic16/adc.h: added GPL info,
+ * src/pic16/gen.c (genIfxpCOpJump): perform an genIfxJump but using
+ a pCodeOp as tested operand,
+ * (genNearPointerGet): optimized bit testing, does not use
+ intermediate register for bit value, test directly instead with
+ BTFSS, BTFSC, works only for single bits,
+ * (genpic16Code): dump the name of the iCode in the asm,
+ * src/pic16/ralloc.c (decodeOp): removed static declaration and
+ renamed to pic16_decodeOp,
+ * (serialRegAssign): do not allocate a temporary register for iCode
+ sequences that test a single bit for 1/0

+
+ * src/pic16/pcode.[ch]: introduced pic16_stackpnt_*,
+ pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
+ access stack and frame pointers. They are initially assigned to
+ point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
+ accessing SFRs. Updated all occurences of modification of stack or
+ frame pointer in gen.c and pcode.c,
+ * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
+ assigning of a literal value to pointers,
+ * src/pic16/main.c (pic16_finiliseOptions): set pre-processor define
+ flag STACK_MODEL_SMALL or STACK_MODEL_LARGE according to the model
+ selected
+
+2005-01-11 Vangelis Rokas <vrokas AT otenet.gr>
+
+ * doc/sdccman.lyx: update documentation about stack pragma, added
+ some info for stack memory models
+
+2005-01-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

+ udata sections to fix bug #1097823
+
+2005-01-05 Raphael Neider <rneider AT web.de>
+
+ * src/pic16/gen.c (genGenericShift): added handling of differently
+ sized left operand and result
+
+2005-01-04 Raphael Neider <rneider AT web.de>
+
+ * src/pic16/gen.c (genIfxJump): fixed inverted skips on CARRY
+ * (genIfx): fixed (?) read from uninitialized SPIL_LOC (now assumes CARRY
+ to hold the condition bit)
+ * added new version of genCmp (old code available via #define)
+ * added new version of genShiftLeft/genShiftRight in a generic
+ way, now supports shifting by negative values
+ * (genLeftShiftLiteral, genRightShiftLiteral): use absolute value of
+ shiftCount (expected by genGenericShift)
+ * src/pic16/genarith.c (genPlus): added code for adding CARRY+literal
+ * src/pic16/pcode.c (pic16_OptimizeJumps): removed annoying statistics
+ dump
+ * (pic16_newpCodeOpLit): changed to cast to unsigned char (as e.g. -32766
+ is an invalid literal too...)
+
+2005-01-04 Vangelis Rokas <vrokas AT otenet.gr>
+
+ * src/pic16/gen.c (aopForSym, genEndFunction): applied some fixes
+ from Raphael Neider,
+ * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
+ for 8-bit literals. This fixes some literal operands which are sign
+ extended to 16-bits ints when instruction needs only 8-bits.
