971 genRightShift): fixed bug with non-constant bit shift stored to
972 a volatile result (SF Open Discussion forum thread #1616749).
973 Single byte case is not yet optimized.

2876 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2878 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2879 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2881 One basic decision: e.g. src/clean.mk includes further files. In order
2882 to make this work there are two solutions:
2883 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2884 run configure on them. This way they can use
2885 'include $(srcdir)/port-clean.mk'
2886 - always include clean.mk by the Makefile at the same level. To avoid
2887 that `make clean` tries to include and build Makefile.dep the
2888 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2889 implemented, because now even `make uninstall` doesn't create
2890 Makefile.in. clean.mk could be eliminated by pasting it in
2893 * debugger/mcs51/Makefile.in: build own objects from library sources
2894 (SLIB, SDCC) in current directory
2896 * configure, configure.in: renamed --disable-device-lib-build in
2897 --disable-device-lib; added --enable-doc, the required tools are
2898 searched by configure; added result message; the toolchain for the
2899 belonging ports are now only built, if the port is enabled.
2901 * support/regression/*: all output is written in directory gen, because
2902 the fwk and ports directories don't livet in the build tree using vpath
2904 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2905 --disable-device-lib, added --enable-doc, added section VPATH
2907 * sim/ucsim/configure.in,
2908 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2909 z80 are enabled by default
2911 2006-04-24 Raphael Neider <rneider AT web.de>
2913 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2914 to config word, "pic14_"-prefixed some extern functions
2915 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2916 config word has been found
2917 * src/pic/device.h: added prototypes
2918 * src/pic/pcode.c: added "pic14_"-prefix where needed
2919 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2921 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2924 (pic14createInterruptVect): moved generating __config directives away
2925 (picglue): have __config directives emitted

3159 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3161 * src/mcs51/gen.c (genCall): fixed bug 1457608
3163 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3182 implemented patch 1120823 Thanks to Willy De la Court (normal
3183 interrupts need an interrupt number now if they are made critical),
3184 and enabled nesting of critical functions though not for gbz80
3185 (genCritical, genEndCritical): added functions
3186 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3187 * src/z80/mappings.i: added "ei" to all mappings

3199 the left operand is shorter than the result (c* = lit-c* + int),
3201 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3204 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3206 * src/.version: increased version number to 2.5.5
3207 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3208 linking is done manually in pic16 port's _linkEdit,
3209 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3210 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3211 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3212 allocate asmop as AOP_ACC,
3213 (aopForRemat): added parameter 'bool result' in function declaration,
3214 (pic16_aopGet): return AOP_ACC when accessing WREG,
3215 (pic16_popGetTempReg): minor modification,
3216 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3217 'pic16_allocWithIdx',

3226 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3227 call to allocReg, not by manually allocating a new one,
3228 (pic16_assignRegisters): now before going through the register
3229 allocating functions mark all registers as free. This eliminates some
3230 side effects resulting from peephole parser done earlier in the backbone
3232 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3290 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3291 which dumps before the function entry point a data byte which represents
3292 the number of the local variables used by the specified function, added
3293 'xinst' for initial support for Extended Instruction Support,
3294 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3295 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3296 port->fun_prefix anymore (may change later),
3297 (genFunction, genEndFunction): do not store/restore local registers for
3298 _main (this should take care the --main-return command line option in
3300 (genOr): removed some legacy pic-port instructions,
3301 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3302 performing operations with SFR's causes data to be written more than
3303 once to each SFR. Perhaps SFRs should be handled in special cases...
3304 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3306 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3307 into account for stack starting position,
3308 (struct OPTIONS pic16_optionsTable): added command line argument
3309 --extended or -y for Extended Instruction Support,
3310 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3311 (deassignLRs): *** perhaps the most important change, old 'for' code
3312 (commented out for reference), didn't account for some registers which
3313 were left marked 'not free' after a pointer operation. The change
3314 reduces register usage a lot in some cases
3316 2006-03-04 Borut Razem <borut.razem AT siol.net>
3318 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5579 * (genCmp): adapted to new genSkipc semantics
5580 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
5581 on rIfx (genCmp was broken)
5583 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5585 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5586 * src/z80/main.c (_keywords[]),
5587 * src/SDCCglobal.h (struct options),
5589 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5590 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5591 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5592 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5593 always available in leading double underscore form. The C99 support is
5594 mostly missing, but it's a start.
5595 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5596 reserved identifier "__data".
5598 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
5600 * src/mcs51/peeph.def: fixed bug 1170013
5602 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

5608 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
5611 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5613 * src/port.h (struct PORT),

5642 immedDom() returning wrong block; probably fixes bug #1160833)
5644 2005-03-20 Borut Razem <borut.razem AT siol.net>
5646 * support/scripts/inc2h.pl: WIN32 port
5648 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5650 * device/lib/makefile.in: added abs.c and labs.c
5652 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5654 * device/include/stdint.h: added
5655 * device/lib/abs.c: added
5656 * device/lib/labs.c: added
5657 * device/include/stdlib.h: added abs() and labs() prototypes

5674 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5676 * device/lib/printf_large.c: removed inline assembly for portability and
5677 readability. Use printf_fast if speed or size are more important.
5678 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5679 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5681 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5683 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5684 prevent compiler warning
5686 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5688 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5689 moved to level 0 and declared as static. Also they are explicit
5690 placed in access bank. This was necessery because some times they
5691 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5692 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5693 optimizations. Currently only compare to unsigned char is implemented,
5694 * src/pic16/gen.c: added fReturnIdx array,
5695 * (struct resolvedIfx) is moved to gen.h and made public,
5696 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5697 * (aopForSym): added an optimization to directly store in stack of
5698 the operand of a SEND iCode,
5699 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5700 but as registers instead (AOP_REG) using the fReturnIdx array,
5701 * (pic16_freeAsmop): remove the freed register from the
5702 _G.sregsAlloc field,
5703 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5704 a compare of 'WREG',
5705 * (pic16_popGetTempRegCond): changed function prototype, now
5706 function takes also a bitVector argument v which holds the current
5707 set of registers that are allocated for stack access by aopForSym,
5708 registers allocated in aopForSym for accessing stack symbols are not
5709 any more part of the functions usedRegs field,
5710 * (genCall): some times aopOp is called for a stack variable to be
5711 send, aopForSym might perform the push, if this is true make sure
5712 that genCall doesn't push the variable twice by testing _G.resDirect,
5713 * (genFunction): changed testing for unspecified interrupt number
5714 from 256 to INTNO_UNSPEC,
5715 * modified selection scheme of frame pointer generation. Previously
5716 if function did use local registers a frame pointer was generated,
5717 now a frame pointer is generated only if function has arguments
5718 (that need PLUSW2 register access), or has stack arguments, or the
5719 compiler is not instructed to omit the frame pointer,
5720 * (genEndFunction): before restoring local registers that were saved
5721 in the function preamble, also restore the registers that *might*
5722 have been allocated for stack access,
5723 * (genRet): removed some old comments,
5724 * (genCmp, the active (RN's) version): added a call to the
5725 pic16_genCmp_special function to perform the compare with a more
5726 robust and optimized way,
5727 * (genInline): a feature has been added in inline code generation,
5728 which allows a wildcard variable substitution when writing inline
5729 assembly. Code is incomplete and experimental therefore undocumented,
5730 * (genCast): changed order of aopOp for result and right to allow
5731 aopForSym to directly load the result if possible,
5732 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5733 perform an optimized compare on some selected special occasions,
5734 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5735 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5736 generate an IVT any more,
5737 * src/pic16/main.c (pic16_optionsTable): added command line option
5739 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5740 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5742 * src/pic16/NOTES: Raphael Neider added in list of active developers
5743 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5744 jumptable_end to prevent bug #,
5745 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5746 inCond and outCond fields,
5747 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5748 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5749 turn off register spilling,
5750 * (packRegsForOneUse): synced with other ports' versions although it
5751 is not used currently,
5752 * (pic16_packRegisters): added an optimization while reading
5753 structure bitfields, some registers may be saved (malloc code is
5754 decreased by 80 bytes)
5756 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5758 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5759 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5760 this can be optimized more?
5762 2005-03-10 Raphael Neider <rneider AT web.de>
5764 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5765 genNearPointerGet): (hopefully) fixed access to bitfields via
5766 pointers (p->bitN = x; and x = p->bitN; failed)
5768 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5954 of (byte sized) temporaries (assign them to WREG for now)
5955 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5956 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5957 this might fix SIGSEGVs on MinGW...
5958 * src/SDCCopt.c (killDeadCode): restored original behaviour
5959 (volatile operands might get thrown away though)
5961 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5963 * src/pic16/gen.c: fixed bug #1106975,

6430 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6432 Large cummulative patch for pic16 port.
6433 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6434 to call when a stack overflow occurs,
6435 * (malloc.h): added CVS Id tag,
6436 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6438 * added libc directory. The current version of LibC contains string
6439 functions, ctype functions and macros and some functions of the
6440 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6441 be extensively tested in the future. Standard disclaimer here.
6442 Library is not automatically build yet. But one can build it by
6443 invoking 'make' inside the libc directory.
6444 * added ADC library under libio. Preliminary version yet.
6446 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6447 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6448 aopForRemat() now and not by pic16_aopOp(),
6449 * (pic16_popGetTempReg): removed warning messgae when allocating
6450 temporary registers, its a buggy feature and will be removed,
6451 * (pic16_popGet): set register instance field in AOP_CRY,
6452 * (pic16_outBitC): fixed for results in size greater than 1,
6453 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6454 * (pic16_storeForReturn): optimized return of 0,
6455 * (genCmp): experimental code for new genCmp which uses PIC18's
6456 special compare&skip instructions. Initial tests fail some times
6457 with variables grater than 1 byte in size, so new code is disabled,
6458 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6460 * (genCast): began a fix to optimize the casting of a bit to another
6461 bit, now assigning a bitfield to another bitfield will fail, sorry,
6462 * src/pic16/main.c: disabled the use of lr-support feature,
6463 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6464 * added some function prototypes, added function _debugf prototype,
6465 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6466 bits with offset (case PO_GPR_BIT),
6467 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6469 * (isBankInstruction): modified to return 0 for no banking instruction,
6470 and 1 for banking instruction,
6471 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6472 caused stop processing pCodes after a inline assembly block,
6473 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6474 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6475 registers when it shouldn't,
6476 * src/pic16/ralloc.c (allocReg): add preliminary support for
6477 supporting a limited set of temporary registers,
6479 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6481 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6482 genDataPointerSet): ensure assignments always copy in MSB to LSB
6484 (loadRegFromAop): recognize CLRH optimization,
6485 (genFunction): optimize RECEIVE iCodes in reentrant functions
6487 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6489 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6490 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6492 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6498 * device/lib/_gptrget.c (_gptrget),
6499 * device/lib/_gptrgetc.c (_gptrgetc),
6500 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6501 instead of sjmp to ret
6502 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6503 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6505 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9484 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9486 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9487 loaded with the linker search paths (-L arguments) and the libraries
9488 to be linked with the current source (-l arguments). Changes
9489 currently will affect only the pic16 port.
9490 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9491 include path the port specific paths and port specific libraries,
9492 * gplink command now contains the $3 argument,
9493 * src/pic16/device.h,
9494 * src/pic16/device.c,: structure PIC_device is made public and
9495 renamed to PIC16_device, the same for variable Pics which is renamed

9510 Documenting changes from previous commits.
9511 * configure.in (version 1.56),
9512 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9513 when generating output files to configure the pic16 library,
9514 but now I've commented it out, since gputils aren't installed in the
9515 SF compile farm, so library won't compile
9517 * device/lib/Makefile.in (version 1.56): initially I've added in
9518 target 'all' the prerequestive 'model-pic16' so it compiled the
9519 pic16 library, but now I've commented it out for the same reasons
9521 * added targets 'model-pic16' and 'objects-pic16' to compile the
9523 * added target 'port-specific-objects-pic16' to handle the
9524 generated libraries and copy them into the build/ directory
9525 * added target 'clean-intermediate-pic16' to clean intermediate
9526 files into pic16 directory
9527 * in target 'installdirs' added line to create directory pic16 in

9578 via literal number. The symbol is placed in the corresponding
9579 position of the data ram
9580 * (pic16_dump_section): relocatable and absolute uninitialized
9581 data are now emitted in sorted order to reduce section naming,
9582 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9583 weren't marked as being in the access bank,
9585 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9587 Added portion of GNU PIC Library under the directory
9588 device/include/pic16 and device/lib/pic16. These files
9589 contain the declarations of SFRs for the PIC18Fxx2 devices.

9620 all over. Telling LaTeX to be less strict with word spacing
9621 to better keep the right margin. Changed some notes about
9622 maintainance of the ports in section 3.2.1 - is it OK like this?
9624 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9664 * src/pic16/peeph.def: all peepholes with movff are commented out,
9665 because there is a problem in the pcode peep optimizer,
9666 * src/pic16/ralloc.c: the register allocator can now reuse local

9703 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9706 * src/z80/main.c: added missed needLinkerScript flags (more than
9707 one port structure defined in these file)
9708 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9731 directive when no overlay data exist
9732 * (picglue): modified to emit uninitialized data segment
9733 according to udata_section_name

9759 include information about variables allocated to the overlay
9762 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9764 * as/mcs51/lkmain.c: Help about -Y option

9776 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9778 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9779 (default behaviour).
9781 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9783 A python script to validate compiler diagnostic messages. It can be
9784 used to verify that sdcc complains about bad c source code and
9785 gives a good location of the error.
9786 * support/valdiag/Makefile,
9787 * support/valdiag/valdiag.py,
9788 * support/valdiag/tests/*
9790 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9792 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9803 * src/common.h: added ifndef/define/endif macros
9804 around the header file.
9805 Bug reported from Jesus Calvino-Fraga
9807 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9809 * sdcc.spec: updated
9810 * device/include/Makefile.in: don't install CVS directories
9811 * device/lib/Makefile.in: added removal of CVS directories after install
9812 * doc/Makefile: fixed install, added local_icons
9813 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9814 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9815 * src/ds390/gen.c (genRightShift): fixed bug #870788
9816 * src/SDCCast.c (decorateType): fixed bug #870781
9818 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9820 PIC16 port related changes:
9821 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9822 added variable stackPos,
9824 * gen.c: genCall, assignResultValue: added support for
9825 pushing/retrieving function parameters to/from stack,
9826 genFunction,genEndFunction: setup stack frame for the
9828 genAddrOf: will be changed according to bug 863624
9830 * added files genutils.c and genutils.h which contain gen*
9831 debugged and optimised functions extracted from gen.c
9833 * glue.c: added variable 'externs' which holds extern symbols,
9834 pic16emitRegularMap: is modified to properly handle relocatable
9835 symbols under the new scheme,
9836 pic16createInterruptVect: is modified
9837 pic16printPublics: is modified to emit 'global' assembler directives,
9838 added pic16_printExterns to print extern symbols,
9839 pic16glue: initializes stack/frame pointer in the beginning of
9840 the assembly output. Temporary hack, will be corrected later,
9841 because gplink yet does not support stack and SDCC does not
9842 yet support a type of crt0.o object to create the final binary.
9844 * Removed many lines that contain 8051 legacy code.
9845 * The code is finally placed under a 'code' directive.
9846 * Added port specific options.
9848 * _process_pragma: simplified since now we do not need *special*
9849 include file to define SFR registers. But a separate header
9850 will be needed. This will be developed later.
9851 * _pic16_parseOptions: added, parses port specific options:
9852 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9853 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9854 --preplace-udata-with=
9856 * _pic16_setDefaultOptions: modified to initialize section names,
9857 but hack is temporarly out of order since it needs improvement.
9858 * _pic16_genAssemblerPreamble: configuration words are emitted by
9859 their address instead of their name. This part is incomplete and
9860 supports only the 18Fxx2 devices. Other devices will emit an error
9861 during assembly since they do not contain the same set of config
9863 * _pic16_genIVT: is modified,
9865 * pcode.c: added definitions for some hardware registers that are needed
9867 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9868 All PCI entries are updated. Now LFSR is supported.
9869 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9870 * added pic16_newpCodeOpLit2 to support instructions with
9871 two literal arguments
9872 * pic16_pCode2str: corrected code that emits assembler instructions
9873 with two literal operands and those that have an access bit modifier
9874 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9875 this fixes a bug which caused some labels to be lost, when an
9876 assembler directive was added, i.e. banksel,
9877 * pic16_FixRegisterBanking: improved logic that causes the insertion
9879 * InlineFunction: functions that are called once, are not any more
9880 inlined. This can be a port option in the future,
9882 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9884 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9885 hold the corresponding uninitialized symbols,
9886 * pic16_allocProcessorRegister: registers have explicit marked the
9888 * pic16_allocInternalRegister: registers are explicit marked as
9890 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9891 processing list, so bit registers were lost,
9894 * ralloc.h: added field 'accessBank' and original symbol operand
9895 in register definition,
9896 * removed the field isMapped from register definition,
9898 ** Several functions have been removed from various sources:
9899 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9900 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9901 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9902 pic16_assignRelocatableRegisters
9904 ** others have been introduced:
9905 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9906 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9908 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9910 * support/scripts/inc2h.pl: changed definition of BIT_AT
9911 to emit 'sbit at' instead of 'bit at'. This was a request.
9913 PIC16 port related preliminary changes:
9914 * gen.c: prefixed function popRegFromString with
9915 pic16_ and all references to it corrected
9916 * pcode.c: all pic16_pc_* hardware registers prefixed
9917 with underscore (_),
9918 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9919 * ralloc.c: newReg(): when register is REG_SFR then
9920 set address to rIdx,
9921 pic16_allocProcessorRegister(): marks register wasUsed=0
9922 pic16_writeUsedRegs(): added a call to assign processor
9923 registers via pic16_assignFixedRegisters
9925 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9927 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9928 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9929 variables in unused register banks. Also the SSEG is placed
9930 wherever there is enough space for it, and IDATA can be anywhere
9931 in internal RAM. For now compile using -Wl-Y[stack_size].
9932 The mem file is different for this option as well, since it
9933 makes no sense of talking about DSEG lenght.
9935 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9937 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9938 in certain cases, e.g. when ROM assignment, patch provided
9939 from Albert den Haan.
9941 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10184 it breaks with bitfields, extern declarations, and gcse analysis.
10185 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10186 could be assigned through a pointer, so don't complain.

10471 * src/SDCC.lex: sdcc now understands both formats:
10472 '# <line_number> <file_name>' and
10473 '#line <line_number> <file_name>'
10474 * support/cpp2/cppmain.c: sdcpp now generates the standard
10475 '# <line_number> <file_name>' instead of former
10476 '#line <line_number> <file_name>'

10486 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10488 Fixed a number of problems revealed by bug #827883.
10489 * src/SDCCloop.c (loopInvariants): Spill location of the
10490 result operand should be recomputed if extracted from
10491 a loop. Also, don't extract assignments of an iTemp
10493 * src/SDCCast.c (isConformingBody): loop reversal should
10494 not occur if the control variable is involved with a
10495 relational operator.

10965 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10966 type for bits was changed. It resulted in bit variables becoming
10967 global, which is not permitted in PIC 14 assembly output.
10969 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10971 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10973 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10975 Z80 and MCS51 linkers complaint if a public symbol is defined
10976 in more than one library module:

10984 A few small changes that speed up the peephole optimizer.
10988 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10990 Try to make the peephole optimizer smarter by maintaining
10991 an association between the assembly source code and the
10992 iCodes that originated them. Put this information to use
10993 with a new peephole rule condition "notVolatile" so that
10994 the rules can be aggressive yet still safe.
10999 * src/mcs51/peeph.def
11001 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11005 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11006 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11007 if the left or right operand symbols have the accuse flag set.
11009 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11011 Changed the type of the result of the ! (NOT) operator to char;
11012 previously it returned the same type as the source. This allows
11013 us to eliminate all the genFloatNot functions (all of its target
11014 implementations were very buggy) since !float can use the same
11017 * src/SDCCicode.c (ast2iCode): ! returns char
11018 * src/mcs51/gen.c (genNot, genNotFloat),
11019 * src/ds390/gen.c (genNot, genNotFloat),
11020 * src/z80/gen.c (genNot, genNotFloat),
11021 * src/pic/gen.c (genNot, genNotFloat),
11022 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11026 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11027 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11028 during interrupts. Ensure WSAVE is located at a shared bank address.
11029 2. Fixed page selection in some places
11030 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11031 the registers name strings.
11032 4. Fixed "signed / unsigned compare" compiler warnings.
11033 5. The PIC port manages its own allocation of the general purpose
11034 registers, but makes no attempt to reuse them. As a result when
11035 compiling it soon runs out of general purpose registers. Some
11036 additional code was added to the files pcode.c and device.c to walk
11037 through the function call tree and rename the registers so that they
11047 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11048 genPlus() & genMinus() when the result is the same as left or right
11050 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11054 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11056 Made bitfield a distinct type from bit so that bitfields
11057 convert as per ANSI C and bits retain their traditional
11058 boolean style behaviour. Implemented bitfield support in
11066 * src/ds390/gen.c: bit v bitfield split
11067 * src/z80/gen.c: New support for bitfields
11068 * support/regression/tests/bitfields.c: reenabled z80,
11071 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11073 Rules 246.x, 247.x relate to bitfields, the others speed up
11074 access to xdata mapped I/O devices.
11076 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11078 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11080 Cleaned up genPackBits and genUnpackBits and added two helper
11081 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11082 for literal assignments in genPackBits (thanks to Frieder for
11088 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11090 Fixed bug #748310 (pointer to function type mishandled when the
11091 function name is omitted). Also fixed a SIGSEGV when a function
11092 attribute (reentrant, etc) is used on a non-function or on a
11093 function but misplaced before the parameter list.
11095 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11097 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11098 * support/Util/SDCCerr.h,
11099 * support/Util/SDCCerr.c: Added func attr misuse error msg
11101 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11103 Fixed bug #787649 by anonymous
11104 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11105 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11107 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11109 Fixed numerous bitfield problems.
11111 * src/SDCC.y: More bitfield related error checking

11118 * support/regression/tests/bitfields.c: tests added
11120 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11122 Made the constant following the "interrupt" keyword optional. If
11123 omitted, the function will not automatically be given an entry
11124 in the interrupt vector table (similar to #pragma NOIV, but
11125 less syntacticly kludgy). The interrupt number is also now
11126 range checked. Also fixed a bug in the high order bit example
11133 * support/Util/SDCCerr.c
11134 * support/Util/SDCCerr.h
11137 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11140 * src/SDCCicode.c (operandOperation): rewritten some ops
11141 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11142 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11144 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11145 be re-activated by defining REDUCE_LITERALS)
11146 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11147 unsigned, but are signed by default
11148 * src/SDCCval.c (constVal): rearranged
11149 * src/SDCCval.c (valMod): preliminary fix
11150 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11190 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11191 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11192 constants are unsigned; added recognition of "u" flag for unsigned
11193 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11194 * src/SDCCval.c (valDiv, valMod): fixed signdness

11602 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11603 the regression tests I'm not brave enough to enable 245.b, 245.c
11604 * doc/sdccman.lyx: added latex preamble for hyperref package.
11605 Using pdflatex this will give you a hyperlinked pdf file with

11656 added if/endif conditional macros to remove options help
11657 messages from optionsTable when a port is not configured, added
11658 support for the PIc16 port in the ports table, when executing
11659 the compiler with no port specified on command line, a default
11660 port is selected with the new macro DEFAULT_PORT which is
11661 defined in port.h, in setDefaultOptions() linkOptions is removed
11662 from initialization assignment, since now it is a set,
11663 parseCmdLine uses setParseWithComma for linkOptions, in
11664 linkEdit() linkOptions are accessed with new function indexSet()
11665 which returns the i'th item of a set variable. See SDCCset.c, in
11666 linkEdit() when calling buildCmdLine(), added linkOptions as
11667 last argument. Now users can pass arguments to gplink via the
11668 -Wl option, main() uses pic16glue() to glue up pic16 programs

11680 * src/pic16/glue.c: commented out some error producing lines
11681 * src/pic16/main.c: __config directives are commented out to stop
11682 gpasm complaining and test the linkage with gplink, _linkCmd and
11683 _asmCmd changed to be more gplink and gpasm friendly
11684 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11685 produced an error when parsed, peep rule 12 is added to utilize
11686 movff, but it is commented out since the pCode does not support
11687 yet a command with 2 address arguments
11689 2003-05-18 <johan AT balder>
11691 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12798 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12799 area BSEG. Also moves, if possible, the DATA area down into the internal
12800 ram so more space is available.
12802 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12805 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12806 not bytes. Function summary() which creates a memory usage summary
12807 file with extension .mem. Reports of overlaping stack and small stack
12808 size. If the space for the stack is less than 16 bytes aslink trows a
12811 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12812 the 8051. Option 'y' for memory summary output file.
12814 Changes to sdcc (All the changes are marked with 'JCF'):
12816 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12818 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12819 overlaying area for it (uses RegBankUsed[4]).
12821 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12822 bank zero as used by default. By default aslink locates the stack
12823 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12824 the creation of the .mem file. Delegates the allocation of data area
12825 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12826 the begining of the stack area to aslink.
12828 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12829 glue() in SDCCglue.c creates an area for it.
12831 2002-09-03 Borut Razem <borut.razem AT siol.net>
12832 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12833 sdcc/src/pic/glue.c:
12834 introduced atexit() handler for teporay files removal in case of
12835 errors, assertions, ...
12837 2002-08-29 Borut Razem <borut.razem AT siol.net>
12838 * sdcc/support/cpp2/auto-host_vc_in.h:
12839 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12840 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12841 Maybe there is a similar problem with BORLANDC? It should be checked!
12843 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12844 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12845 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12846 was not executed, and the compiler (cl) launched a warning:
12847 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12849 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12850 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12852 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12853 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12855 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12856 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12857 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12858 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12859 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12860 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12861 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12862 - added Release configuration in VS projects
12863 - review of compiler an linker options
12864 - VC .exe files are generated in bin_vc directory, not to interfere
12865 with binaries generated from other projects (cygwin, mingw, bcc ...)
12867 * sdcc/src/yacc.dsp: added
12869 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12870 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12871 and insert the version number definitions from .version
12873 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12875 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12876 added - genarate auto-host.h using auto-host_vc_in.h as template
12879 removed from CVS, generated automatically
12881 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12882 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12884 2002-08-11 Borut Razem <borut.razem AT siol.net>
12885 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12887 2002-08-10 Borut Razem <borut.razem AT siol.net>
12888 * src/SDCCmain.c (main):
12889 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12890 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12891 The consequence was that some temporary files were not removed.
12894 unification of code in functions tempfilename() and tempfile():
12895 function tempnam() is defined in Visual Studio 6.0 and .NET
12897 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12899 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12900 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12901 - removed compiler command line option /WX: Treats all warnings as errors
12902 - update a list of source files, included into the project
12904 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12905 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12906 changed project type to Generic Project so that can be correcly converted to VS.NET project
12908 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12910 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12912 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12914 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12915 added return 0 statements after assert() to make compiler happy
12917 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12918 added newline in the def file to keep MSC compiler satisfied
12920 * sdcc/src/z80/gen.c:
12921 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12922 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12923 - solved MSC error in function aopDump()
12925 * sdcc_vc.h: define PREFIX as "\\sdcc"
12927 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12928 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12965 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12967 2002-03-28 Johan Knol <johan AT balder>
12969 * src/SDCCval.c: fixed bug #532436
12971 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12976 Added -p option. Allows port dependent processor to be specified.
12979 Initialized the new field char *Processor field to NULL in all ports
12982 Compiler generated registers for interrupt context saving
12983 were not getting allocated.
12985 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

13100 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13102 * sdcc/src/SDCCloop.c:
13103 Previous fix was not good. basic blocks that have "break" or "return" are
13104 not really partof a loop , but live ranges used in these blocks should
13105 be live thru the entire loop, so set partOfLoop but don't add them to
13108 2002-02-21 <johan AT FRIJA>
13110 * src/SDCCcse.c: fixed bug #514308
13112 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

13116 statement inside a loop, it was not being considered part of the loop.
13118 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13120 2002-02-10 Karl Bongers <karl AT turbobit.com>
