2369 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2371 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2372 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2374 One basic decision: e.g. src/clean.mk includes further files. In order
2375 to make this work there are two solutions:
2376 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2377 run configure on them. This way they can use
2378 'include $(srcdir)/port-clean.mk'
2379 - always include clean.mk by the Makefile at the same level. To avoid
2380 that `make clean` tries to include and build Makefile.dep the
2381 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2382 implemented, because now even `make uninstall` doesn't create
2383 Makefile.in. clean.mk could be eliminated by pasting it in
2386 * debugger/mcs51/Makefile.in: build own objects from library sources
2387 (SLIB, SDCC) in current directory
2389 * configure, configure.in: renamed --disable-device-lib-build in
2390 --disable-device-lib; added --enable-doc, the required tools are
2391 searched by configure; added result message; the toolchain for the
2392 belonging ports are now only built, if the port is enabled.
2394 * support/regression/*: all output is written in directory gen, because
2395 the fwk and ports directories don't livet in the build tree using vpath
2397 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2398 --disable-device-lib, added --enable-doc, added section VPATH
2400 * sim/ucsim/configure.in,
2401 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2402 z80 are enabled by default
2404 2006-04-24 Raphael Neider <rneider AT web.de>
2406 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2407 to config word, "pic14_"-prefixed some extern functions
2408 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2409 config word has been found
2410 * src/pic/device.h: added prototypes
2411 * src/pic/pcode.c: added "pic14_"-prefix where needed
2412 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2414 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2428 fixes #1469504 and #1474602,
2429 (pCodeRegOptimizeRegUsage): fixed typo in comment

2652 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2654 * src/mcs51/gen.c (genCall): fixed bug 1457608
2656 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2661 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2663 * src/SDCCpeeph.c (operandsLiteral): new, added,

2675 implemented patch 1120823 Thanks to Willy De la Court (normal
2676 interrupts need an interrupt number now if they are made critical),
2677 and enabled nesting of critical functions though not for gbz80
2678 (genCritical, genEndCritical): added functions
2679 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2680 * src/z80/mappings.i: added "ei" to all mappings
2682 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2684 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2685 submitted by the Debian SDCC maintainer Aurelien Jarno:
2686 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2687 archive with gcc 4.1 on mips and wrote the patch"
2689 2006-03-16 Raphael Neider <rneider AT web.de>
2691 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2692 the left operand is shorter than the result (c* = lit-c* + int),
2694 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2697 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2699 * src/.version: increased version number to 2.5.5
2700 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2701 linking is done manually in pic16 port's _linkEdit,
2702 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2703 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2704 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2705 allocate asmop as AOP_ACC,
2706 (aopForRemat): added parameter 'bool result' in function declaration,
2707 (pic16_aopGet): return AOP_ACC when accessing WREG,
2708 (pic16_popGetTempReg): minor modification,
2709 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2710 'pic16_allocWithIdx',
2711 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2712 calling function in absolute addresses,
2713 (genAssign): take into account AOP_ACC asmop,
2714 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2715 * src/pic16/pcoderegs.c: some debug functions and lines added,
2716 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2717 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2719 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2720 call to allocReg, not by manually allocating a new one,
2721 (pic16_assignRegisters): now before going through the register
2722 allocating functions mark all registers as free. This eliminates some
2723 side effects resulting from peephole parser done earlier in the backbone
2725 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2727 * src/SDCCicode.c (geniCodeLogic),

2746 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2747 (aopForSym, aopOp): increment asmop.allocated if reused,
2748 (freeAsmop): decrement asmop.allocated and check for zero instead of
2750 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2751 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2752 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2775 2006-03-06 Borut Razem <borut.razem AT siol.net>
2777 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2778 made the linker quiet
2780 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2782 * src/pic16/gen.c (genPcall): fixed bug #1443644
2783 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2784 which dumps before the function entry point a data byte which represents
2785 the number of the local variables used by the specified function, added
2786 'xinst' for initial support for Extended Instruction Support,
2787 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2788 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2789 port->fun_prefix anymore (may change later),
2790 (genFunction, genEndFunction): do not store/restore local registers for
2791 _main (this should take care the --main-return command line option in
2793 (genOr): removed some legacy pic-port instructions,
2794 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2795 performing operations with SFR's causes data to be written more than
2796 once to each SFR. Perhaps SFRs should be handled in special cases...
2797 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2799 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2800 into account for stack starting position,
2801 (struct OPTIONS pic16_optionsTable): added command line argument
2802 --extended or -y for Extended Instruction Support,
2803 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2804 (deassignLRs): *** perhaps the most important change, old 'for' code
2805 (commented out for reference), didn't account for some registers which
2806 were left marked 'not free' after a pointer operation. The change
2807 reduces register usage a lot in some cases
2809 2006-03-04 Borut Razem <borut.razem AT siol.net>
2811 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5133 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5134 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5135 immedDom() returning wrong block; probably fixes bug #1160833)
5137 2005-03-20 Borut Razem <borut.razem AT siol.net>
5139 * support/scripts/inc2h.pl: WIN32 port
5141 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5143 * device/lib/makefile.in: added abs.c and labs.c
5145 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5147 * device/include/stdint.h: added
5148 * device/lib/abs.c: added
5149 * device/lib/labs.c: added
5150 * device/include/stdlib.h: added abs() and labs() prototypes
5151 * device/lib/libsdcc.lib: added abs and labs
5152 * device/include/float.h,
5153 * device/lib/_fsmul.c,
5154 * device/lib/printf_fast.c,
5155 * device/lib/printf_tiny.c: updated comments
5157 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5159 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5162 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5164 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5165 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5167 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5169 * device/lib/printf_large.c: removed inline assembly for portability and
5170 readability. Use printf_fast if speed or size are more important.
5171 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5172 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5174 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5176 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5177 prevent compiler warning
5179 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5181 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5182 moved to level 0 and declared as static. Also they are explicit
5183 placed in access bank. This was necessery because some times they
5184 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5185 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5186 optimizations. Currently only compare to unsigned char is implemented,
5187 * src/pic16/gen.c: added fReturnIdx array,
5188 * (struct resolvedIfx) is moved to gen.h and made public,
5189 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5190 * (aopForSym): added an optimization to directly store in stack of
5191 the operand of a SEND iCode,
5192 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5193 but as registers instead (AOP_REG) using the fReturnIdx array,
5194 * (pic16_freeAsmop): remove the freed register from the
5195 _G.sregsAlloc field,
5196 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5197 a compare of 'WREG',
5198 * (pic16_popGetTempRegCond): changed function prototype, now
5199 function takes also a bitVector argument v which holds the current
5200 set of registers that are allocated for stack access by aopForSym,
5201 registers allocated in aopForSym for accessing stack symbols are not
5202 any more part of the functions usedRegs field,
5203 * (genCall): some times aopOp is called for a stack variable to be
5204 send, aopForSym might perform the push, if this is true make sure
5205 that genCall doesn't push the variable twice by testing _G.resDirect,
5206 * (genFunction): changed testing for unspecified interrupt number
5207 from 256 to INTNO_UNSPEC,
5208 * modified selection scheme of frame pointer generation. Previously
5209 if function did use local registers a frame pointer was generated,
5210 now a frame pointer is generated only if function has arguments
5211 (that need PLUSW2 register access), or has stack arguments, or the
5212 compiler is not instructed to omit the frame pointer,
5213 * (genEndFunction): before restoring local registers that were saved
5214 in the function preamble, also restore the registers that *might*
5215 have been allocated for stack access,
5216 * (genRet): removed some old comments,
5217 * (genCmp, the active (RN's) version): added a call to the
5218 pic16_genCmp_special function to perform the compare with a more
5219 robust and optimized way,
5220 * (genInline): a feature has been added in inline code generation,
5221 which allows a wildcard variable substitution when writing inline
5222 assembly. Code is incomplete and experimental therefore undocumented,
5223 * (genCast): changed order of aopOp for result and right to allow
5224 aopForSym to directly load the result if possible,
5225 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5226 perform an optimized compare on some selected special occasions,
5227 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5228 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5229 generate an IVT any more,
5230 * src/pic16/main.c (pic16_optionsTable): added command line option
5232 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5233 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5235 * src/pic16/NOTES: Raphael Neider added in list of active developers
5236 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5237 jumptable_end to prevent bug #,
5238 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5239 inCond and outCond fields,
5240 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5241 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5242 turn off register spilling,
5243 * (packRegsForOneUse): synced with other ports' versions although it
5244 is not used currently,
5245 * (pic16_packRegisters): added an optimization while reading
5246 structure bitfields, some registers may be saved (malloc code is
5247 decreased by 80 bytes)
5249 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5251 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5252 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5253 this can be optimized more?
5255 2005-03-10 Raphael Neider <rneider AT web.de>
5257 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5258 genNearPointerGet): (hopefully) fixed access to bitfields via
5259 pointers (p->bitN = x; and x = p->bitN; failed)
5261 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5302 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5304 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5305 to keep the correct label reference count when adding/removing references
5306 to labels. A peephole file using this is appended to patch #1144962.

5448 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5449 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5450 this might fix SIGSEGVs on MinGW...
5451 * src/SDCCopt.c (killDeadCode): restored original behaviour
5452 (volatile operands might get thrown away though)
5454 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5538 * (genUminus): rewritten to for efficiency
5539 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5540 used uninitialized in some cases)

5542 copy the third byte from the int -- now assumes 0x80 (data memory)
5543 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5544 operands (genAddLit expects the iCode's operands to swapped as
5545 well), fixed leftover bytes (crashed for short left operands)

5931 * added libc directory. The current version of LibC contains string
5932 functions, ctype functions and macros and some functions of the
5933 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5934 be extensively tested in the future. Standard disclaimer here.
5935 Library is not automatically build yet. But one can build it by

5947 * (pic16_storeForReturn): optimized return of 0,
5948 * (genCmp): experimental code for new genCmp which uses PIC18's
5949 special compare&skip instructions. Initial tests fail some times
5950 with variables grater than 1 byte in size, so new code is disabled,
5951 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5953 * (genCast): began a fix to optimize the casting of a bit to another
5954 bit, now assigning a bitfield to another bitfield will fail, sorry,

5963 and 1 for banking instruction,
5964 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5965 caused stop processing pCodes after a inline assembly block,

5968 registers when it shouldn't,
5969 * src/pic16/ralloc.c (allocReg): add preliminary support for
5970 supporting a limited set of temporary registers,
5972 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5975 genDataPointerSet): ensure assignments always copy in MSB to LSB
5977 (loadRegFromAop): recognize CLRH optimization,
5978 (genFunction): optimize RECEIVE iCodes in reentrant functions
5980 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5982 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8977 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8979 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8980 loaded with the linker search paths (-L arguments) and the libraries
8981 to be linked with the current source (-l arguments). Changes
8982 currently will affect only the pic16 port.
8983 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8984 include path the port specific paths and port specific libraries,
8985 * gplink command now contains the $3 argument,
8986 * src/pic16/device.h,
8987 * src/pic16/device.c,: structure PIC_device is made public and
8988 renamed to PIC16_device, the same for variable Pics which is renamed

9003 Documenting changes from previous commits.
9004 * configure.in (version 1.56),
9005 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9006 when generating output files to configure the pic16 library,
9007 but now I've commented it out, since gputils aren't installed in the
9008 SF compile farm, so library won't compile
9010 * device/lib/Makefile.in (version 1.56): initially I've added in
9011 target 'all' the prerequestive 'model-pic16' so it compiled the
9012 pic16 library, but now I've commented it out for the same reasons
9014 * added targets 'model-pic16' and 'objects-pic16' to compile the
9016 * added target 'port-specific-objects-pic16' to handle the
9017 generated libraries and copy them into the build/ directory
9018 * added target 'clean-intermediate-pic16' to clean intermediate
9019 files into pic16 directory
9020 * in target 'installdirs' added line to create directory pic16 in
9021 the installation path
9023 * device/include/Makefile.in (version 1.11): in target 'install'
9024 added lines to copy all header files to installation path,
9025 * in target 'installdirs' added line create directory for pic16
9026 headers in the installation path

9041 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9042 option so that it actually works. Made it specific to the z80, since
9043 the gbz80 doesn't have these kinds of I/O ports.
9045 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9047 * device/include/z180.h,

9071 via literal number. The symbol is placed in the corresponding
9072 position of the data ram
9073 * (pic16_dump_section): relocatable and absolute uninitialized
9074 data are now emitted in sorted order to reduce section naming,
9075 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9076 weren't marked as being in the access bank,
9078 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9080 Added portion of GNU PIC Library under the directory
9081 device/include/pic16 and device/lib/pic16. These files
9082 contain the declarations of SFRs for the PIC18Fxx2 devices.
9083 The directory is initialized via configure from toplevel.
9085 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

9110 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9112 * doc/sdccman.lyx: Moved and added some sections, small changes
9113 all over. Telling LaTeX to be less strict with word spacing
9114 to better keep the right margin. Changed some notes about
9115 maintainance of the ports in section 3.2.1 - is it OK like this?
9117 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9119 SDCC source changes:
9120 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9126 processor registers declared internally by the port are emitted in
9127 the translation as equates,
9128 * src/pic16/gen.c: inline code is passed unprocessed to the

9154 UPPER for immediate operands,
9155 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9157 * src/pic16/peeph.def: all peepholes with movff are commented out,
9158 because there is a problem in the pcode peep optimizer,
9159 * src/pic16/ralloc.c: the register allocator can now reuse local

9236 2004-01-07 Borut Razem <borut.razem AT siol.net>
9238 * support/scripts/sdcc.nsi: update PATH
9239 * support/scripts/sdcc.ico: craeted

9269 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9271 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9272 (default behaviour).
9274 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9276 A python script to validate compiler diagnostic messages. It can be
9277 used to verify that sdcc complains about bad c source code and
9278 gives a good location of the error.
9279 * support/valdiag/Makefile,
9280 * support/valdiag/valdiag.py,
9281 * support/valdiag/tests/*

9296 * src/common.h: added ifndef/define/endif macros
9297 around the header file.
9298 Bug reported from Jesus Calvino-Fraga
9300 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9302 * sdcc.spec: updated
9303 * device/include/Makefile.in: don't install CVS directories
9304 * device/lib/Makefile.in: added removal of CVS directories after install
9305 * doc/Makefile: fixed install, added local_icons
9306 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9307 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9308 * src/ds390/gen.c (genRightShift): fixed bug #870788
9309 * src/SDCCast.c (decorateType): fixed bug #870781
9311 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9313 PIC16 port related changes:
9314 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9315 added variable stackPos,
9317 * gen.c: genCall, assignResultValue: added support for
9318 pushing/retrieving function parameters to/from stack,
9319 genFunction,genEndFunction: setup stack frame for the
9321 genAddrOf: will be changed according to bug 863624
9323 * added files genutils.c and genutils.h which contain gen*
9324 debugged and optimised functions extracted from gen.c
9326 * glue.c: added variable 'externs' which holds extern symbols,
9327 pic16emitRegularMap: is modified to properly handle relocatable
9328 symbols under the new scheme,
9329 pic16createInterruptVect: is modified
9330 pic16printPublics: is modified to emit 'global' assembler directives,
9331 added pic16_printExterns to print extern symbols,
9332 pic16glue: initializes stack/frame pointer in the beginning of
9333 the assembly output. Temporary hack, will be corrected later,
9334 because gplink yet does not support stack and SDCC does not
9335 yet support a type of crt0.o object to create the final binary.
9337 * Removed many lines that contain 8051 legacy code.
9338 * The code is finally placed under a 'code' directive.
9339 * Added port specific options.
9341 * _process_pragma: simplified since now we do not need *special*
9342 include file to define SFR registers. But a separate header
9343 will be needed. This will be developed later.
9344 * _pic16_parseOptions: added, parses port specific options:
9345 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9346 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9347 --preplace-udata-with=
9349 * _pic16_setDefaultOptions: modified to initialize section names,
9350 but hack is temporarly out of order since it needs improvement.
9351 * _pic16_genAssemblerPreamble: configuration words are emitted by
9352 their address instead of their name. This part is incomplete and
9353 supports only the 18Fxx2 devices. Other devices will emit an error
9354 during assembly since they do not contain the same set of config
9356 * _pic16_genIVT: is modified,
9358 * pcode.c: added definitions for some hardware registers that are needed
9360 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9361 All PCI entries are updated. Now LFSR is supported.
9362 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9363 * added pic16_newpCodeOpLit2 to support instructions with
9364 two literal arguments
9365 * pic16_pCode2str: corrected code that emits assembler instructions
9366 with two literal operands and those that have an access bit modifier
9367 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9368 this fixes a bug which caused some labels to be lost, when an
9369 assembler directive was added, i.e. banksel,
9370 * pic16_FixRegisterBanking: improved logic that causes the insertion
9372 * InlineFunction: functions that are called once, are not any more
9373 inlined. This can be a port option in the future,
9375 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9377 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9378 hold the corresponding uninitialized symbols,
9379 * pic16_allocProcessorRegister: registers have explicit marked the
9381 * pic16_allocInternalRegister: registers are explicit marked as
9383 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9384 processing list, so bit registers were lost,
9387 * ralloc.h: added field 'accessBank' and original symbol operand
9388 in register definition,
9389 * removed the field isMapped from register definition,
9391 ** Several functions have been removed from various sources:
9392 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9393 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9394 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9395 pic16_assignRelocatableRegisters
9397 ** others have been introduced:
9398 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9399 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9401 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9403 * support/scripts/inc2h.pl: changed definition of BIT_AT
9404 to emit 'sbit at' instead of 'bit at'. This was a request.
9406 PIC16 port related preliminary changes:
9407 * gen.c: prefixed function popRegFromString with
9408 pic16_ and all references to it corrected
9409 * pcode.c: all pic16_pc_* hardware registers prefixed
9410 with underscore (_),
9411 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9412 * ralloc.c: newReg(): when register is REG_SFR then
9413 set address to rIdx,
9414 pic16_allocProcessorRegister(): marks register wasUsed=0
9415 pic16_writeUsedRegs(): added a call to assign processor
9416 registers via pic16_assignFixedRegisters
9418 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9420 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9421 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9422 variables in unused register banks. Also the SSEG is placed
9423 wherever there is enough space for it, and IDATA can be anywhere
9424 in internal RAM. For now compile using -Wl-Y[stack_size].
9425 The mem file is different for this option as well, since it
9426 makes no sense of talking about DSEG lenght.
9428 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9430 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9431 in certain cases, e.g. when ROM assignment, patch provided
9432 from Albert den Haan.
9434 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9577 * src/mcs51/peephole.def,
9578 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9579 (allows non-interrupt and interrupt code to safely compete for a resource

10319 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10320 support for standard C idiom of memory mapped variables; for
10321 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10322 to xdata int at 0x1234 tempvar = 1.
10323 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10340 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10342 Fixed bug #621531 (const & volatile confusion in the type chain).
10343 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10344 refer to the const or volatile state of the pointer itself.

10422 * src/mcs51/gen.c (leftRightUseAcc),
10423 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10424 iCode properly now. Use getSize instead of nRegs since a & b
10425 aren't part of the nRegs tally.
10427 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10429 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10439 copied from genNearPointerSet()
10440 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10441 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10442 If they pop r0/r1 they must be called in the opposite order than aopOp().
10443 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10444 (resp. --stack-auto), prepared for --xstack

10455 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10457 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10458 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10459 type for bits was changed. It resulted in bit variables becoming
10460 global, which is not permitted in PIC 14 assembly output.
10462 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10464 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10477 A few small changes that speed up the peephole optimizer.
10481 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10483 Try to make the peephole optimizer smarter by maintaining
10484 an association between the assembly source code and the
10485 iCodes that originated them. Put this information to use
10486 with a new peephole rule condition "notVolatile" so that
10487 the rules can be aggressive yet still safe.
10492 * src/mcs51/peeph.def
10494 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10498 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10499 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10500 if the left or right operand symbols have the accuse flag set.
10502 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10504 Changed the type of the result of the ! (NOT) operator to char;
10505 previously it returned the same type as the source. This allows
10506 us to eliminate all the genFloatNot functions (all of its target
10507 implementations were very buggy) since !float can use the same

10519 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10520 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10521 during interrupts. Ensure WSAVE is located at a shared bank address.
10522 2. Fixed page selection in some places
10523 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10524 the registers name strings.
10525 4. Fixed "signed / unsigned compare" compiler warnings.
10526 5. The PIC port manages its own allocation of the general purpose
10527 registers, but makes no attempt to reuse them. As a result when
10528 compiling it soon runs out of general purpose registers. Some
10529 additional code was added to the files pcode.c and device.c to walk
10530 through the function call tree and rename the registers so that they
10540 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10541 genPlus() & genMinus() when the result is the same as left or right
10543 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10547 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10549 Made bitfield a distinct type from bit so that bitfields
10550 convert as per ANSI C and bits retain their traditional
10551 boolean style behaviour. Implemented bitfield support in
10559 * src/ds390/gen.c: bit v bitfield split
10560 * src/z80/gen.c: New support for bitfields
10561 * support/regression/tests/bitfields.c: reenabled z80,
10564 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10566 Rules 246.x, 247.x relate to bitfields, the others speed up
10567 access to xdata mapped I/O devices.
10569 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10571 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10573 Cleaned up genPackBits and genUnpackBits and added two helper
10574 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10575 for literal assignments in genPackBits (thanks to Frieder for
10581 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10583 Fixed bug #748310 (pointer to function type mishandled when the
10584 function name is omitted). Also fixed a SIGSEGV when a function
10585 attribute (reentrant, etc) is used on a non-function or on a
10586 function but misplaced before the parameter list.

10616 omitted, the function will not automatically be given an entry
10617 in the interrupt vector table (similar to #pragma NOIV, but
10618 less syntacticly kludgy). The interrupt number is also now

11123 * src/pic16/pcodeflow.c: Cleaned warnings
11124 * src/pic16/pcoderegs.c: Cleaned warnings
11126 2003-05-19 Scott Dattalo <scott AT dattalo.com>
11128 * src/pic16/pcode.c: Cleaned warnings
11129 * src/pic16/pcodepeep.c: Cleaned warnings
11130 * src/pic16/ralloc.c: Cleaned warnings

11137 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
11139 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11140 it can be defined with CFLAGS when running configure
11141 * src/SDCCmain.c: fixed compiling + linking with object files
11143 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
11145 * configure.in: configure for pic16 port,
11146 added --disable-pic16-port
11147 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
11148 * src/SDCCmain.c: linkOptions is changed to set *,
11149 added if/endif conditional macros to remove options help
11150 messages from optionsTable when a port is not configured, added
11151 support for the PIc16 port in the ports table, when executing
11152 the compiler with no port specified on command line, a default
11153 port is selected with the new macro DEFAULT_PORT which is
11154 defined in port.h, in setDefaultOptions() linkOptions is removed
11155 from initialization assignment, since now it is a set,
11156 parseCmdLine uses setParseWithComma for linkOptions, in
11157 linkEdit() linkOptions are accessed with new function indexSet()
11158 which returns the i'th item of a set variable. See SDCCset.c, in
11159 linkEdit() when calling buildCmdLine(), added linkOptions as
11160 last argument. Now users can pass arguments to gplink via the
11161 -Wl option, main() uses pic16glue() to glue up pic16 programs
11162 * src/SDCCpeeph.c: various changes to support pic16
11163 * src/SDCCset.c: added function void *indexSet(set *, int) to
11164 return the i'th item of the set
11165 * src/SDCCset.h: added function prototype for indexSet()
11166 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
11167 * src/clean.mk: added pic16 in CLEANALLPORTS variable

11169 added macro DEFAULT_PORT
11170 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
11171 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
11173 * src/pic16/glue.c: commented out some error producing lines
11174 * src/pic16/main.c: __config directives are commented out to stop
11175 gpasm complaining and test the linkage with gplink, _linkCmd and
11176 _asmCmd changed to be more gplink and gpasm friendly
11177 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11178 produced an error when parsed, peep rule 12 is added to utilize
11179 movff, but it is commented out since the pCode does not support
11180 yet a command with 2 address arguments
11182 2003-05-18 <johan AT balder>
11184 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12245 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12247 * in /sdcc/as/mcs51/ changed these files in order to create an
12248 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12249 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12250 following files to include the previous two files: aslink.dsp,
12251 Makefile.aslink, Makefile.bcc, and Makefile.in.
12253 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12254 .adb instead of .cdb
12256 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12258 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12259 value from option --iram-size.
12261 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12263 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12266 2002-09-18 <wiml AT hhhh.org>
12268 * SDCClrange.h: exposed setFromRange() and setToRange()
12269 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12270 packRegsForAccUse() (bug 542397)
12271 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12272 multiple times and emitting the fetch operations more than once
12273 added aopGetUsesAcc() function to allow binary operators to
12274 fetch their operands in the correct order; made genMinus() emit
12275 compact code for X = LITERAL - Y
12277 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12278 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12279 sprintf() in line 1267.
12281 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12282 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12285 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12286 Changes to aslink (All the changes are marked with 'JCF'):
12288 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12291 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12292 area BSEG. Also moves, if possible, the DATA area down into the internal
12293 ram so more space is available.
12295 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12298 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12299 not bytes. Function summary() which creates a memory usage summary
12300 file with extension .mem. Reports of overlaping stack and small stack
12301 size. If the space for the stack is less than 16 bytes aslink trows a
12304 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12305 the 8051. Option 'y' for memory summary output file.
12307 Changes to sdcc (All the changes are marked with 'JCF'):
12309 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12311 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12312 overlaying area for it (uses RegBankUsed[4]).
12314 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12315 bank zero as used by default. By default aslink locates the stack
12316 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12317 the creation of the .mem file. Delegates the allocation of data area
12318 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12319 the begining of the stack area to aslink.
12321 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12322 glue() in SDCCglue.c creates an area for it.
12324 2002-09-03 Borut Razem <borut.razem AT siol.net>
12325 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12326 sdcc/src/pic/glue.c:
12327 introduced atexit() handler for teporay files removal in case of
12328 errors, assertions, ...
12330 2002-08-29 Borut Razem <borut.razem AT siol.net>
12331 * sdcc/support/cpp2/auto-host_vc_in.h:
12332 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12333 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12334 Maybe there is a similar problem with BORLANDC? It should be checked!
12336 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12337 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12338 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12339 was not executed, and the compiler (cl) launched a warning:
12340 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12342 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12343 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12345 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

12354 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12355 - added Release configuration in VS projects
12356 - review of compiler an linker options
12357 - VC .exe files are generated in bin_vc directory, not to interfere
12358 with binaries generated from other projects (cygwin, mingw, bcc ...)
12360 * sdcc/src/yacc.dsp: added
12362 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12363 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12364 and insert the version number definitions from .version
12366 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12368 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12369 added - genarate auto-host.h using auto-host_vc_in.h as template
12372 removed from CVS, generated automatically
12374 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12375 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12377 2002-08-11 Borut Razem <borut.razem AT siol.net>
12378 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12380 2002-08-10 Borut Razem <borut.razem AT siol.net>
12381 * src/SDCCmain.c (main):
12382 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12383 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12384 The consequence was that some temporary files were not removed.
12387 unification of code in functions tempfilename() and tempfile():
12388 function tempnam() is defined in Visual Studio 6.0 and .NET
12390 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12392 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12393 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12394 - removed compiler command line option /WX: Treats all warnings as errors
12395 - update a list of source files, included into the project
12397 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12398 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12399 changed project type to Generic Project so that can be correcly converted to VS.NET project
12401 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12403 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12407 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12408 added return 0 statements after assert() to make compiler happy
12410 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12411 added newline in the def file to keep MSC compiler satisfied
12413 * sdcc/src/z80/gen.c:
12414 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12415 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12416 - solved MSC error in function aopDump()
12418 * sdcc_vc.h: define PREFIX as "\\sdcc"
12420 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12475 Compiler generated registers for interrupt context saving
12476 were not getting allocated.
12478 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

12593 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12595 * sdcc/src/SDCCloop.c:
12596 Previous fix was not good. basic blocks that have "break" or "return" are
12597 not really partof a loop , but live ranges used in these blocks should
