2368 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2370 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2371 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2373 One basic decision: e.g. src/clean.mk includes further files. In order
2374 to make this work there are two solutions:
2375 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2376 run configure on them. This way they can use
2377 'include $(srcdir)/port-clean.mk'
2378 - always include clean.mk by the Makefile at the same level. To avoid
2379 that `make clean` tries to include and build Makefile.dep the
2380 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2381 implemented, because now even `make uninstall` doesn't create
2382 Makefile.in. clean.mk could be eliminated by pasting it in
2385 * debugger/mcs51/Makefile.in: build own objects from library sources
2386 (SLIB, SDCC) in current directory
2388 * configure, configure.in: renamed --disable-device-lib-build in
2389 --disable-device-lib; added --enable-doc, the required tools are
2390 searched by configure; added result message; the toolchain for the
2391 belonging ports are now only built, if the port is enabled.
2393 * support/regression/*: all output is written in directory gen, because
2394 the fwk and ports directories don't livet in the build tree using vpath
2396 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2397 --disable-device-lib, added --enable-doc, added section VPATH
2399 * sim/ucsim/configure.in,
2400 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2401 z80 are enabled by default
2403 2006-04-24 Raphael Neider <rneider AT web.de>
2405 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2406 to config word, "pic14_"-prefixed some extern functions
2407 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2408 config word has been found
2409 * src/pic/device.h: added prototypes
2410 * src/pic/pcode.c: added "pic14_"-prefix where needed
2411 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2413 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2427 fixes #1469504 and #1474602,
2428 (pCodeRegOptimizeRegUsage): fixed typo in comment

2651 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2653 * src/mcs51/gen.c (genCall): fixed bug 1457608
2655 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2657 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

2660 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2662 * src/SDCCpeeph.c (operandsLiteral): new, added,
2663 (callFuncByName): inserted operandsLiteral

2673 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2674 implemented patch 1120823 Thanks to Willy De la Court (normal
2675 interrupts need an interrupt number now if they are made critical),
2676 and enabled nesting of critical functions though not for gbz80
2677 (genCritical, genEndCritical): added functions
2678 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2679 * src/z80/mappings.i: added "ei" to all mappings
2681 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2683 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2684 submitted by the Debian SDCC maintainer Aurelien Jarno:
2685 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2686 archive with gcc 4.1 on mips and wrote the patch"
2688 2006-03-16 Raphael Neider <rneider AT web.de>
2690 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2691 the left operand is shorter than the result (c* = lit-c* + int),
2693 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2696 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2698 * src/.version: increased version number to 2.5.5
2699 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2700 linking is done manually in pic16 port's _linkEdit,
2701 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2702 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2703 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2704 allocate asmop as AOP_ACC,
2705 (aopForRemat): added parameter 'bool result' in function declaration,
2706 (pic16_aopGet): return AOP_ACC when accessing WREG,
2707 (pic16_popGetTempReg): minor modification,
2708 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2709 'pic16_allocWithIdx',
2710 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2711 calling function in absolute addresses,
2712 (genAssign): take into account AOP_ACC asmop,
2713 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2714 * src/pic16/pcoderegs.c: some debug functions and lines added,

2716 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2718 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2719 call to allocReg, not by manually allocating a new one,
2720 (pic16_assignRegisters): now before going through the register
2721 allocating functions mark all registers as free. This eliminates some
2722 side effects resulting from peephole parser done earlier in the backbone
2724 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2726 * src/SDCCicode.c (geniCodeLogic),

2745 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2746 (aopForSym, aopOp): increment asmop.allocated if reused,
2747 (freeAsmop): decrement asmop.allocated and check for zero instead of
2749 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2750 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2751 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2774 2006-03-06 Borut Razem <borut.razem AT siol.net>
2776 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2777 made the linker quiet
2779 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2781 * src/pic16/gen.c (genPcall): fixed bug #1443644
2782 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2783 which dumps before the function entry point a data byte which represents
2784 the number of the local variables used by the specified function, added
2785 'xinst' for initial support for Extended Instruction Support,
2786 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2787 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2788 port->fun_prefix anymore (may change later),
2789 (genFunction, genEndFunction): do not store/restore local registers for
2790 _main (this should take care the --main-return command line option in
2792 (genOr): removed some legacy pic-port instructions,
2793 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2794 performing operations with SFR's causes data to be written more than
2795 once to each SFR. Perhaps SFRs should be handled in special cases...
2796 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2798 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2799 into account for stack starting position,
2800 (struct OPTIONS pic16_optionsTable): added command line argument
2801 --extended or -y for Extended Instruction Support,
2802 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2803 (deassignLRs): *** perhaps the most important change, old 'for' code
2804 (commented out for reference), didn't account for some registers which
2805 were left marked 'not free' after a pointer operation. The change
2806 reduces register usage a lot in some cases
2808 2006-03-04 Borut Razem <borut.razem AT siol.net>

5131 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
5132 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5133 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5134 immedDom() returning wrong block; probably fixes bug #1160833)
5136 2005-03-20 Borut Razem <borut.razem AT siol.net>
5138 * support/scripts/inc2h.pl: WIN32 port
5140 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5142 * device/lib/makefile.in: added abs.c and labs.c
5144 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5146 * device/include/stdint.h: added
5147 * device/lib/abs.c: added
5148 * device/lib/labs.c: added
5149 * device/include/stdlib.h: added abs() and labs() prototypes
5150 * device/lib/libsdcc.lib: added abs and labs
5151 * device/include/float.h,
5152 * device/lib/_fsmul.c,
5153 * device/lib/printf_fast.c,
5154 * device/lib/printf_tiny.c: updated comments
5156 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5158 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5161 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5163 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5164 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5166 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5168 * device/lib/printf_large.c: removed inline assembly for portability and
5169 readability. Use printf_fast if speed or size are more important.
5170 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5171 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5173 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5175 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5176 prevent compiler warning
5178 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5180 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5181 moved to level 0 and declared as static. Also they are explicit
5182 placed in access bank. This was necessery because some times they
5183 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5184 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5185 optimizations. Currently only compare to unsigned char is implemented,
5186 * src/pic16/gen.c: added fReturnIdx array,
5187 * (struct resolvedIfx) is moved to gen.h and made public,
5188 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5189 * (aopForSym): added an optimization to directly store in stack of
5190 the operand of a SEND iCode,
5191 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5192 but as registers instead (AOP_REG) using the fReturnIdx array,
5193 * (pic16_freeAsmop): remove the freed register from the
5194 _G.sregsAlloc field,
5195 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5196 a compare of 'WREG',
5197 * (pic16_popGetTempRegCond): changed function prototype, now
5198 function takes also a bitVector argument v which holds the current
5199 set of registers that are allocated for stack access by aopForSym,
5200 registers allocated in aopForSym for accessing stack symbols are not
5201 any more part of the functions usedRegs field,
5202 * (genCall): some times aopOp is called for a stack variable to be
5203 send, aopForSym might perform the push, if this is true make sure
5204 that genCall doesn't push the variable twice by testing _G.resDirect,
5205 * (genFunction): changed testing for unspecified interrupt number
5206 from 256 to INTNO_UNSPEC,
5207 * modified selection scheme of frame pointer generation. Previously
5208 if function did use local registers a frame pointer was generated,
5209 now a frame pointer is generated only if function has arguments
5210 (that need PLUSW2 register access), or has stack arguments, or the
5211 compiler is not instructed to omit the frame pointer,
5212 * (genEndFunction): before restoring local registers that were saved
5213 in the function preamble, also restore the registers that *might*
5214 have been allocated for stack access,
5215 * (genRet): removed some old comments,
5216 * (genCmp, the active (RN's) version): added a call to the
5217 pic16_genCmp_special function to perform the compare with a more
5218 robust and optimized way,
5219 * (genInline): a feature has been added in inline code generation,
5220 which allows a wildcard variable substitution when writing inline
5221 assembly. Code is incomplete and experimental therefore undocumented,
5222 * (genCast): changed order of aopOp for result and right to allow
5223 aopForSym to directly load the result if possible,
5224 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5225 perform an optimized compare on some selected special occasions,
5226 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5227 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5228 generate an IVT any more,
5229 * src/pic16/main.c (pic16_optionsTable): added command line option
5231 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5232 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5234 * src/pic16/NOTES: Raphael Neider added in list of active developers
5235 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5236 jumptable_end to prevent bug #,
5237 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5238 inCond and outCond fields,
5239 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5240 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5241 turn off register spilling,
5242 * (packRegsForOneUse): synced with other ports' versions although it
5243 is not used currently,
5244 * (pic16_packRegisters): added an optimization while reading
5245 structure bitfields, some registers may be saved (malloc code is
5246 decreased by 80 bytes)
5248 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5250 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5251 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5252 this can be optimized more?
5254 2005-03-10 Raphael Neider <rneider AT web.de>
5256 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5257 genNearPointerGet): (hopefully) fixed access to bitfields via
5258 pointers (p->bitN = x; and x = p->bitN; failed)
5260 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5301 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5303 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5304 to keep the correct label reference count when adding/removing references
5305 to labels. A peephole file using this is appended to patch #1144962.

5448 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5449 this might fix SIGSEGVs on MinGW...
5450 * src/SDCCopt.c (killDeadCode): restored original behaviour
5451 (volatile operands might get thrown away though)
5453 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5537 * (genUminus): rewritten to for efficiency
5538 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5539 used uninitialized in some cases)

5541 copy the third byte from the int -- now assumes 0x80 (data memory)
5542 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5543 operands (genAddLit expects the iCode's operands to swapped as
5544 well), fixed leftover bytes (crashed for short left operands)

5930 * added libc directory. The current version of LibC contains string
5931 functions, ctype functions and macros and some functions of the
5932 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5933 be extensively tested in the future. Standard disclaimer here.

5947 * (genCmp): experimental code for new genCmp which uses PIC18's
5948 special compare&skip instructions. Initial tests fail some times
5949 with variables grater than 1 byte in size, so new code is disabled,
5950 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5952 * (genCast): began a fix to optimize the casting of a bit to another
5953 bit, now assigning a bitfield to another bitfield will fail, sorry,

5968 * src/pic16/ralloc.c (allocReg): add preliminary support for
5969 supporting a limited set of temporary registers,
5971 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5977 (genFunction): optimize RECEIVE iCodes in reentrant functions
5979 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5981 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8976 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8978 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8979 loaded with the linker search paths (-L arguments) and the libraries
8980 to be linked with the current source (-l arguments). Changes
8981 currently will affect only the pic16 port.
8982 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8983 include path the port specific paths and port specific libraries,
8984 * gplink command now contains the $3 argument,
8985 * src/pic16/device.h,
8986 * src/pic16/device.c,: structure PIC_device is made public and
8987 renamed to PIC16_device, the same for variable Pics which is renamed

9002 Documenting changes from previous commits.
9003 * configure.in (version 1.56),
9004 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9005 when generating output files to configure the pic16 library,
9006 but now I've commented it out, since gputils aren't installed in the
9007 SF compile farm, so library won't compile
9009 * device/lib/Makefile.in (version 1.56): initially I've added in
9010 target 'all' the prerequestive 'model-pic16' so it compiled the
9011 pic16 library, but now I've commented it out for the same reasons
9013 * added targets 'model-pic16' and 'objects-pic16' to compile the
9015 * added target 'port-specific-objects-pic16' to handle the
9016 generated libraries and copy them into the build/ directory
9017 * added target 'clean-intermediate-pic16' to clean intermediate
9018 files into pic16 directory
9019 * in target 'installdirs' added line to create directory pic16 in
9020 the installation path
9022 * device/include/Makefile.in (version 1.11): in target 'install'
9023 added lines to copy all header files to installation path,
9024 * in target 'installdirs' added line create directory for pic16
9025 headers in the installation path

9040 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9041 option so that it actually works. Made it specific to the z80, since
9042 the gbz80 doesn't have these kinds of I/O ports.
9044 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9046 * device/include/z180.h,

9070 via literal number. The symbol is placed in the corresponding
9071 position of the data ram
9072 * (pic16_dump_section): relocatable and absolute uninitialized
9073 data are now emitted in sorted order to reduce section naming,
9074 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9075 weren't marked as being in the access bank,
9077 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9079 Added portion of GNU PIC Library under the directory
9080 device/include/pic16 and device/lib/pic16. These files
9081 contain the declarations of SFRs for the PIC18Fxx2 devices.
9082 The directory is initialized via configure from toplevel.

9093 2004-01-12 Borut Razem <borut.razem AT siol.net>
9095 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
9096 doc/sdccman.lyx: upper case pragmas are deprecated
9098 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

9111 * doc/sdccman.lyx: Moved and added some sections, small changes
9112 all over. Telling LaTeX to be less strict with word spacing
9113 to better keep the right margin. Changed some notes about
9114 maintainance of the ports in section 3.2.1 - is it OK like this?
9116 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9118 SDCC source changes:
9119 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9125 processor registers declared internally by the port are emitted in
9126 the translation as equates,
9127 * src/pic16/gen.c: inline code is passed unprocessed to the

9153 UPPER for immediate operands,
9154 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9156 * src/pic16/peeph.def: all peepholes with movff are commented out,
9157 because there is a problem in the pcode peep optimizer,
9158 * src/pic16/ralloc.c: the register allocator can now reuse local

9235 2004-01-07 Borut Razem <borut.razem AT siol.net>
9237 * support/scripts/sdcc.nsi: update PATH
9238 * support/scripts/sdcc.ico: craeted

9245 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9247 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9249 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9251 include information about variables allocated to the overlay
9254 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9256 * as/mcs51/lkmain.c: Help about -Y option

9268 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9270 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9271 (default behaviour).
9273 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9275 A python script to validate compiler diagnostic messages. It can be
9276 used to verify that sdcc complains about bad c source code and
9277 gives a good location of the error.
9278 * support/valdiag/Makefile,
9279 * support/valdiag/valdiag.py,
9280 * support/valdiag/tests/*
9282 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9295 * src/common.h: added ifndef/define/endif macros
9296 around the header file.
9297 Bug reported from Jesus Calvino-Fraga
9299 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9301 * sdcc.spec: updated
9302 * device/include/Makefile.in: don't install CVS directories
9303 * device/lib/Makefile.in: added removal of CVS directories after install
9304 * doc/Makefile: fixed install, added local_icons
9305 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9306 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9307 * src/ds390/gen.c (genRightShift): fixed bug #870788
9308 * src/SDCCast.c (decorateType): fixed bug #870781
9310 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9312 PIC16 port related changes:
9313 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9314 added variable stackPos,
9316 * gen.c: genCall, assignResultValue: added support for
9317 pushing/retrieving function parameters to/from stack,
9318 genFunction,genEndFunction: setup stack frame for the
9320 genAddrOf: will be changed according to bug 863624
9322 * added files genutils.c and genutils.h which contain gen*
9323 debugged and optimised functions extracted from gen.c
9325 * glue.c: added variable 'externs' which holds extern symbols,
9326 pic16emitRegularMap: is modified to properly handle relocatable
9327 symbols under the new scheme,
9328 pic16createInterruptVect: is modified
9329 pic16printPublics: is modified to emit 'global' assembler directives,
9330 added pic16_printExterns to print extern symbols,
9331 pic16glue: initializes stack/frame pointer in the beginning of
9332 the assembly output. Temporary hack, will be corrected later,
9333 because gplink yet does not support stack and SDCC does not
9334 yet support a type of crt0.o object to create the final binary.
9336 * Removed many lines that contain 8051 legacy code.
9337 * The code is finally placed under a 'code' directive.
9338 * Added port specific options.
9340 * _process_pragma: simplified since now we do not need *special*
9341 include file to define SFR registers. But a separate header
9342 will be needed. This will be developed later.
9343 * _pic16_parseOptions: added, parses port specific options:
9344 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9345 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9346 --preplace-udata-with=
9348 * _pic16_setDefaultOptions: modified to initialize section names,
9349 but hack is temporarly out of order since it needs improvement.
9350 * _pic16_genAssemblerPreamble: configuration words are emitted by
9351 their address instead of their name. This part is incomplete and
9352 supports only the 18Fxx2 devices. Other devices will emit an error
9353 during assembly since they do not contain the same set of config
9355 * _pic16_genIVT: is modified,
9357 * pcode.c: added definitions for some hardware registers that are needed
9359 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9360 All PCI entries are updated. Now LFSR is supported.
9361 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9362 * added pic16_newpCodeOpLit2 to support instructions with
9363 two literal arguments
9364 * pic16_pCode2str: corrected code that emits assembler instructions
9365 with two literal operands and those that have an access bit modifier
9366 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9367 this fixes a bug which caused some labels to be lost, when an
9368 assembler directive was added, i.e. banksel,
9369 * pic16_FixRegisterBanking: improved logic that causes the insertion
9371 * InlineFunction: functions that are called once, are not any more
9372 inlined. This can be a port option in the future,
9374 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9376 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9377 hold the corresponding uninitialized symbols,
9378 * pic16_allocProcessorRegister: registers have explicit marked the
9380 * pic16_allocInternalRegister: registers are explicit marked as
9382 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9383 processing list, so bit registers were lost,
9386 * ralloc.h: added field 'accessBank' and original symbol operand
9387 in register definition,
9388 * removed the field isMapped from register definition,
9390 ** Several functions have been removed from various sources:
9391 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9392 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9393 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9394 pic16_assignRelocatableRegisters
9396 ** others have been introduced:
9397 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9398 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9400 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9402 * support/scripts/inc2h.pl: changed definition of BIT_AT
9403 to emit 'sbit at' instead of 'bit at'. This was a request.
9405 PIC16 port related preliminary changes:
9406 * gen.c: prefixed function popRegFromString with
9407 pic16_ and all references to it corrected
9408 * pcode.c: all pic16_pc_* hardware registers prefixed
9409 with underscore (_),
9410 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9411 * ralloc.c: newReg(): when register is REG_SFR then
9412 set address to rIdx,
9413 pic16_allocProcessorRegister(): marks register wasUsed=0
9414 pic16_writeUsedRegs(): added a call to assign processor
9415 registers via pic16_assignFixedRegisters
9417 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9419 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9420 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9421 variables in unused register banks. Also the SSEG is placed
9422 wherever there is enough space for it, and IDATA can be anywhere
9423 in internal RAM. For now compile using -Wl-Y[stack_size].
9424 The mem file is different for this option as well, since it
9425 makes no sense of talking about DSEG lenght.
9427 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9429 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9430 in certain cases, e.g. when ROM assignment, patch provided
9431 from Albert den Haan.
9433 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9576 * src/mcs51/peephole.def,
9577 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9578 (allows non-interrupt and interrupt code to safely compete for a resource

10318 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10319 support for standard C idiom of memory mapped variables; for
10320 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10321 to xdata int at 0x1234 tempvar = 1.
10322 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10339 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10341 Fixed bug #621531 (const & volatile confusion in the type chain).
10342 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10343 refer to the const or volatile state of the pointer itself.

10421 * src/mcs51/gen.c (leftRightUseAcc),
10422 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10423 iCode properly now. Use getSize instead of nRegs since a & b
10424 aren't part of the nRegs tally.
10426 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10428 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10438 copied from genNearPointerSet()
10439 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10440 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10441 If they pop r0/r1 they must be called in the opposite order than aopOp().
10442 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10443 (resp. --stack-auto), prepared for --xstack

10454 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10456 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10457 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10458 type for bits was changed. It resulted in bit variables becoming
10459 global, which is not permitted in PIC 14 assembly output.
10461 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10463 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10465 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10467 Z80 and MCS51 linkers complaint if a public symbol is defined

10474 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10476 A few small changes that speed up the peephole optimizer.
10480 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10482 Try to make the peephole optimizer smarter by maintaining
10483 an association between the assembly source code and the
10484 iCodes that originated them. Put this information to use
10485 with a new peephole rule condition "notVolatile" so that
10486 the rules can be aggressive yet still safe.
10491 * src/mcs51/peeph.def
10493 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10497 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10498 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10499 if the left or right operand symbols have the accuse flag set.
10501 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10503 Changed the type of the result of the ! (NOT) operator to char;
10504 previously it returned the same type as the source. This allows
10505 us to eliminate all the genFloatNot functions (all of its target
10506 implementations were very buggy) since !float can use the same
10509 * src/SDCCicode.c (ast2iCode): ! returns char

10518 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10519 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10520 during interrupts. Ensure WSAVE is located at a shared bank address.
10521 2. Fixed page selection in some places
10522 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10523 the registers name strings.
10524 4. Fixed "signed / unsigned compare" compiler warnings.
10525 5. The PIC port manages its own allocation of the general purpose
10526 registers, but makes no attempt to reuse them. As a result when
10527 compiling it soon runs out of general purpose registers. Some
10528 additional code was added to the files pcode.c and device.c to walk
10529 through the function call tree and rename the registers so that they
10539 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10540 genPlus() & genMinus() when the result is the same as left or right
10542 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10546 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10548 Made bitfield a distinct type from bit so that bitfields
10549 convert as per ANSI C and bits retain their traditional
10550 boolean style behaviour. Implemented bitfield support in
10558 * src/ds390/gen.c: bit v bitfield split
10559 * src/z80/gen.c: New support for bitfields
10560 * support/regression/tests/bitfields.c: reenabled z80,
10563 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10565 Rules 246.x, 247.x relate to bitfields, the others speed up
10566 access to xdata mapped I/O devices.
10568 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10570 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10572 Cleaned up genPackBits and genUnpackBits and added two helper
10573 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10574 for literal assignments in genPackBits (thanks to Frieder for
10580 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10582 Fixed bug #748310 (pointer to function type mishandled when the
10583 function name is omitted). Also fixed a SIGSEGV when a function
10584 attribute (reentrant, etc) is used on a non-function or on a
10585 function but misplaced before the parameter list.

10615 omitted, the function will not automatically be given an entry
10616 in the interrupt vector table (similar to #pragma NOIV, but
10617 less syntacticly kludgy). The interrupt number is also now

11122 * src/pic16/pcodeflow.c: Cleaned warnings
11123 * src/pic16/pcoderegs.c: Cleaned warnings
11125 2003-05-19 Scott Dattalo <scott AT dattalo.com>
11127 * src/pic16/pcode.c: Cleaned warnings
11128 * src/pic16/pcodepeep.c: Cleaned warnings
11129 * src/pic16/ralloc.c: Cleaned warnings

11136 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
11138 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11139 it can be defined with CFLAGS when running configure
11140 * src/SDCCmain.c: fixed compiling + linking with object files
11142 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
11144 * configure.in: configure for pic16 port,
11145 added --disable-pic16-port
11146 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
11147 * src/SDCCmain.c: linkOptions is changed to set *,
11148 added if/endif conditional macros to remove options help
11149 messages from optionsTable when a port is not configured, added
11150 support for the PIc16 port in the ports table, when executing
11151 the compiler with no port specified on command line, a default
11152 port is selected with the new macro DEFAULT_PORT which is
11153 defined in port.h, in setDefaultOptions() linkOptions is removed
11154 from initialization assignment, since now it is a set,
11155 parseCmdLine uses setParseWithComma for linkOptions, in
11156 linkEdit() linkOptions are accessed with new function indexSet()
11157 which returns the i'th item of a set variable. See SDCCset.c, in
11158 linkEdit() when calling buildCmdLine(), added linkOptions as
11159 last argument. Now users can pass arguments to gplink via the
11160 -Wl option, main() uses pic16glue() to glue up pic16 programs
11161 * src/SDCCpeeph.c: various changes to support pic16
11162 * src/SDCCset.c: added function void *indexSet(set *, int) to
11163 return the i'th item of the set
11164 * src/SDCCset.h: added function prototype for indexSet()
11165 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
11166 * src/clean.mk: added pic16 in CLEANALLPORTS variable

11168 added macro DEFAULT_PORT
11169 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
11170 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
11172 * src/pic16/glue.c: commented out some error producing lines
11173 * src/pic16/main.c: __config directives are commented out to stop
11174 gpasm complaining and test the linkage with gplink, _linkCmd and
11175 _asmCmd changed to be more gplink and gpasm friendly
11176 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11177 produced an error when parsed, peep rule 12 is added to utilize
11178 movff, but it is commented out since the pCode does not support
11179 yet a command with 2 address arguments
11181 2003-05-18 <johan AT balder>
11183 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12244 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12246 * in /sdcc/as/mcs51/ changed these files in order to create an
12247 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12248 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12249 following files to include the previous two files: aslink.dsp,
12250 Makefile.aslink, Makefile.bcc, and Makefile.in.
12252 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12253 .adb instead of .cdb
12255 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12257 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12258 value from option --iram-size.
12260 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12262 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12265 2002-09-18 <wiml AT hhhh.org>
12267 * SDCClrange.h: exposed setFromRange() and setToRange()
12268 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12269 packRegsForAccUse() (bug 542397)
12270 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12271 multiple times and emitting the fetch operations more than once
12272 added aopGetUsesAcc() function to allow binary operators to
12273 fetch their operands in the correct order; made genMinus() emit
12274 compact code for X = LITERAL - Y
12276 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12277 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12278 sprintf() in line 1267.
12280 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12281 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12284 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12285 Changes to aslink (All the changes are marked with 'JCF'):
12287 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12290 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12291 area BSEG. Also moves, if possible, the DATA area down into the internal
12292 ram so more space is available.
12294 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12297 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12298 not bytes. Function summary() which creates a memory usage summary
12299 file with extension .mem. Reports of overlaping stack and small stack
12300 size. If the space for the stack is less than 16 bytes aslink trows a
12303 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12304 the 8051. Option 'y' for memory summary output file.
12306 Changes to sdcc (All the changes are marked with 'JCF'):
12308 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12310 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12311 overlaying area for it (uses RegBankUsed[4]).
12313 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12314 bank zero as used by default. By default aslink locates the stack
12315 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12316 the creation of the .mem file. Delegates the allocation of data area
12317 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12318 the begining of the stack area to aslink.
12320 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12321 glue() in SDCCglue.c creates an area for it.
12323 2002-09-03 Borut Razem <borut.razem AT siol.net>
12324 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12325 sdcc/src/pic/glue.c:
12326 introduced atexit() handler for teporay files removal in case of
12327 errors, assertions, ...
12329 2002-08-29 Borut Razem <borut.razem AT siol.net>
12330 * sdcc/support/cpp2/auto-host_vc_in.h:
12331 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12332 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12333 Maybe there is a similar problem with BORLANDC? It should be checked!
12335 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12336 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12337 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12338 was not executed, and the compiler (cl) launched a warning:
12339 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12341 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12342 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12344 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

12353 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12354 - added Release configuration in VS projects
12355 - review of compiler an linker options
12356 - VC .exe files are generated in bin_vc directory, not to interfere
12357 with binaries generated from other projects (cygwin, mingw, bcc ...)
12359 * sdcc/src/yacc.dsp: added
12361 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12362 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12363 and insert the version number definitions from .version
12365 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12367 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12368 added - genarate auto-host.h using auto-host_vc_in.h as template
12371 removed from CVS, generated automatically
12373 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12374 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12376 2002-08-11 Borut Razem <borut.razem AT siol.net>
12377 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12379 2002-08-10 Borut Razem <borut.razem AT siol.net>
12380 * src/SDCCmain.c (main):
12381 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12382 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12383 The consequence was that some temporary files were not removed.
12386 unification of code in functions tempfilename() and tempfile():
12387 function tempnam() is defined in Visual Studio 6.0 and .NET
12389 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12391 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12392 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12393 - removed compiler command line option /WX: Treats all warnings as errors
12394 - update a list of source files, included into the project
12396 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12397 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12398 changed project type to Generic Project so that can be correcly converted to VS.NET project
12400 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12402 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12406 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12407 added return 0 statements after assert() to make compiler happy
12409 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12410 added newline in the def file to keep MSC compiler satisfied
12412 * sdcc/src/z80/gen.c:
12413 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12414 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12415 - solved MSC error in function aopDump()
12417 * sdcc_vc.h: define PREFIX as "\\sdcc"
12419 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12471 Initialized the new field char *Processor field to NULL in all ports
12474 Compiler generated registers for interrupt context saving
12475 were not getting allocated.
12477 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12480 Fixed left shift. Will promote the left side of a left shift
12481 if a) left shifting more than size of operand or b) when assigned
12482 to something size > size of left side

12592 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12594 * sdcc/src/SDCCloop.c:
12595 Previous fix was not good. basic blocks that have "break" or "return" are
12596 not really partof a loop , but live ranges used in these blocks should
