2783 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2785 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2786 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2788 One basic decision: e.g. src/clean.mk includes further files. In order
2789 to make this work there are two solutions:
2790 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2791 run configure on them. This way they can use
2792 'include $(srcdir)/port-clean.mk'
2793 - always include clean.mk by the Makefile at the same level. To avoid
2794 that `make clean` tries to include and build Makefile.dep the
2795 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2796 implemented, because now even `make uninstall` doesn't create
2797 Makefile.in. clean.mk could be eliminated by pasting it in
2800 * debugger/mcs51/Makefile.in: build own objects from library sources
2801 (SLIB, SDCC) in current directory
2803 * configure, configure.in: renamed --disable-device-lib-build in
2804 --disable-device-lib; added --enable-doc, the required tools are
2805 searched by configure; added result message; the toolchain for the
2806 belonging ports are now only built, if the port is enabled.
2808 * support/regression/*: all output is written in directory gen, because
2809 the fwk and ports directories don't livet in the build tree using vpath
2811 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2812 --disable-device-lib, added --enable-doc, added section VPATH
2814 * sim/ucsim/configure.in,
2815 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2816 z80 are enabled by default
2818 2006-04-24 Raphael Neider <rneider AT web.de>
2820 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2821 to config word, "pic14_"-prefixed some extern functions
2822 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2823 config word has been found
2824 * src/pic/device.h: added prototypes
2825 * src/pic/pcode.c: added "pic14_"-prefix where needed

2828 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2843 (pCodeRegOptimizeRegUsage): fixed typo in comment

3066 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3068 * src/mcs51/gen.c (genCall): fixed bug 1457608
3070 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3072 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

3075 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3077 * src/SDCCpeeph.c (operandsLiteral): new, added,

3088 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3089 implemented patch 1120823 Thanks to Willy De la Court (normal
3090 interrupts need an interrupt number now if they are made critical),
3091 and enabled nesting of critical functions though not for gbz80
3092 (genCritical, genEndCritical): added functions
3093 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3094 * src/z80/mappings.i: added "ei" to all mappings
3096 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3098 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3099 submitted by the Debian SDCC maintainer Aurelien Jarno:
3100 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3101 archive with gcc 4.1 on mips and wrote the patch"
3103 2006-03-16 Raphael Neider <rneider AT web.de>
3105 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3106 the left operand is shorter than the result (c* = lit-c* + int),
3108 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3111 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3113 * src/.version: increased version number to 2.5.5
3114 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3115 linking is done manually in pic16 port's _linkEdit,
3116 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3117 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3118 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3119 allocate asmop as AOP_ACC,
3120 (aopForRemat): added parameter 'bool result' in function declaration,
3121 (pic16_aopGet): return AOP_ACC when accessing WREG,
3122 (pic16_popGetTempReg): minor modification,
3123 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3124 'pic16_allocWithIdx',
3125 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3126 calling function in absolute addresses,
3127 (genAssign): take into account AOP_ACC asmop,
3128 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3129 * src/pic16/pcoderegs.c: some debug functions and lines added,
3130 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3131 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3133 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3134 call to allocReg, not by manually allocating a new one,
3135 (pic16_assignRegisters): now before going through the register
3136 allocating functions mark all registers as free. This eliminates some
3137 side effects resulting from peephole parser done earlier in the backbone
3139 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3141 * src/SDCCicode.c (geniCodeLogic),

3159 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
3160 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3161 (aopForSym, aopOp): increment asmop.allocated if reused,
3162 (freeAsmop): decrement asmop.allocated and check for zero instead of
3164 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3165 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3166 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3189 2006-03-06 Borut Razem <borut.razem AT siol.net>
3191 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3192 made the linker quiet
3194 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3196 * src/pic16/gen.c (genPcall): fixed bug #1443644
3197 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3198 which dumps before the function entry point a data byte which represents
3199 the number of the local variables used by the specified function, added
3200 'xinst' for initial support for Extended Instruction Support,
3201 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3202 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3203 port->fun_prefix anymore (may change later),
3204 (genFunction, genEndFunction): do not store/restore local registers for
3205 _main (this should take care the --main-return command line option in
3207 (genOr): removed some legacy pic-port instructions,
3208 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3209 performing operations with SFR's causes data to be written more than
3210 once to each SFR. Perhaps SFRs should be handled in special cases...
3211 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3213 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3214 into account for stack starting position,
3215 (struct OPTIONS pic16_optionsTable): added command line argument
3216 --extended or -y for Extended Instruction Support,
3217 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3218 (deassignLRs): *** perhaps the most important change, old 'for' code
3219 (commented out for reference), didn't account for some registers which
3220 were left marked 'not free' after a pointer operation. The change
3221 reduces register usage a lot in some cases
3223 2006-03-04 Borut Razem <borut.razem AT siol.net>
3225 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5548 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5549 immedDom() returning wrong block; probably fixes bug #1160833)
5551 2005-03-20 Borut Razem <borut.razem AT siol.net>
5553 * support/scripts/inc2h.pl: WIN32 port
5555 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5557 * device/lib/makefile.in: added abs.c and labs.c
5559 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5561 * device/include/stdint.h: added
5562 * device/lib/abs.c: added
5563 * device/lib/labs.c: added
5564 * device/include/stdlib.h: added abs() and labs() prototypes
5565 * device/lib/libsdcc.lib: added abs and labs
5566 * device/include/float.h,
5567 * device/lib/_fsmul.c,
5568 * device/lib/printf_fast.c,
5569 * device/lib/printf_tiny.c: updated comments
5571 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5573 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5576 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5578 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5579 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5581 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5583 * device/lib/printf_large.c: removed inline assembly for portability and
5584 readability. Use printf_fast if speed or size are more important.
5585 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5586 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5588 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5590 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5591 prevent compiler warning
5593 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5595 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5596 moved to level 0 and declared as static. Also they are explicit
5597 placed in access bank. This was necessery because some times they
5598 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5599 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5600 optimizations. Currently only compare to unsigned char is implemented,
5601 * src/pic16/gen.c: added fReturnIdx array,
5602 * (struct resolvedIfx) is moved to gen.h and made public,
5603 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5604 * (aopForSym): added an optimization to directly store in stack of
5605 the operand of a SEND iCode,
5606 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5607 but as registers instead (AOP_REG) using the fReturnIdx array,
5608 * (pic16_freeAsmop): remove the freed register from the
5609 _G.sregsAlloc field,
5610 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5611 a compare of 'WREG',
5612 * (pic16_popGetTempRegCond): changed function prototype, now
5613 function takes also a bitVector argument v which holds the current
5614 set of registers that are allocated for stack access by aopForSym,
5615 registers allocated in aopForSym for accessing stack symbols are not
5616 any more part of the functions usedRegs field,
5617 * (genCall): some times aopOp is called for a stack variable to be
5618 send, aopForSym might perform the push, if this is true make sure
5619 that genCall doesn't push the variable twice by testing _G.resDirect,
5620 * (genFunction): changed testing for unspecified interrupt number
5621 from 256 to INTNO_UNSPEC,
5622 * modified selection scheme of frame pointer generation. Previously
5623 if function did use local registers a frame pointer was generated,
5624 now a frame pointer is generated only if function has arguments
5625 (that need PLUSW2 register access), or has stack arguments, or the
5626 compiler is not instructed to omit the frame pointer,
5627 * (genEndFunction): before restoring local registers that were saved
5628 in the function preamble, also restore the registers that *might*
5629 have been allocated for stack access,
5630 * (genRet): removed some old comments,
5631 * (genCmp, the active (RN's) version): added a call to the
5632 pic16_genCmp_special function to perform the compare with a more
5633 robust and optimized way,
5634 * (genInline): a feature has been added in inline code generation,
5635 which allows a wildcard variable substitution when writing inline
5636 assembly. Code is incomplete and experimental therefore undocumented,
5637 * (genCast): changed order of aopOp for result and right to allow
5638 aopForSym to directly load the result if possible,
5639 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5640 perform an optimized compare on some selected special occasions,
5641 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5642 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5643 generate an IVT any more,
5644 * src/pic16/main.c (pic16_optionsTable): added command line option
5646 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5647 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5649 * src/pic16/NOTES: Raphael Neider added in list of active developers
5650 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5651 jumptable_end to prevent bug #,
5652 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5653 inCond and outCond fields,
5654 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5655 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5656 turn off register spilling,
5657 * (packRegsForOneUse): synced with other ports' versions although it
5658 is not used currently,
5659 * (pic16_packRegisters): added an optimization while reading
5660 structure bitfields, some registers may be saved (malloc code is
5661 decreased by 80 bytes)
5663 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5665 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5666 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5667 this can be optimized more?
5669 2005-03-10 Raphael Neider <rneider AT web.de>
5671 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5672 genNearPointerGet): (hopefully) fixed access to bitfields via
5673 pointers (p->bitN = x; and x = p->bitN; failed)
5675 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6308 generated for switch statements. For now you need to set the
6309 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6310 Now 4 algorithms for mcs51 jumptable generation are used:
6311 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

6343 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6345 * added libc directory. The current version of LibC contains string
6346 functions, ctype functions and macros and some functions of the
6347 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6348 be extensively tested in the future. Standard disclaimer here.
6349 Library is not automatically build yet. But one can build it by

6361 * (pic16_storeForReturn): optimized return of 0,
6362 * (genCmp): experimental code for new genCmp which uses PIC18's
6363 special compare&skip instructions. Initial tests fail some times
6364 with variables grater than 1 byte in size, so new code is disabled,
6365 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6367 * (genCast): began a fix to optimize the casting of a bit to another
6368 bit, now assigning a bitfield to another bitfield will fail, sorry,

6377 and 1 for banking instruction,
6378 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6379 caused stop processing pCodes after a inline assembly block,
6380 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6382 registers when it shouldn't,
6383 * src/pic16/ralloc.c (allocReg): add preliminary support for
6384 supporting a limited set of temporary registers,
6386 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6392 (genFunction): optimize RECEIVE iCodes in reentrant functions
6394 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6396 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6410 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6412 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9346 code / RAM are in the same page / bank. This means the linker can
9347 safely allocate code/RAM of separate ASM files to different pages/banks.
9348 * doc/sdccman.lyx: added Slade's tips
9349 * src/mcs51/peeph.def: fixed bug #880768

9391 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9393 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9394 loaded with the linker search paths (-L arguments) and the libraries
9395 to be linked with the current source (-l arguments). Changes
9396 currently will affect only the pic16 port.
9397 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9398 include path the port specific paths and port specific libraries,
9399 * gplink command now contains the $3 argument,
9400 * src/pic16/device.h,
9401 * src/pic16/device.c,: structure PIC_device is made public and
9402 renamed to PIC16_device, the same for variable Pics which is renamed

9417 Documenting changes from previous commits.
9418 * configure.in (version 1.56),
9419 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9420 when generating output files to configure the pic16 library,
9421 but now I've commented it out, since gputils aren't installed in the
9422 SF compile farm, so library won't compile
9424 * device/lib/Makefile.in (version 1.56): initially I've added in
9425 target 'all' the prerequestive 'model-pic16' so it compiled the
9426 pic16 library, but now I've commented it out for the same reasons
9428 * added targets 'model-pic16' and 'objects-pic16' to compile the
9430 * added target 'port-specific-objects-pic16' to handle the
9431 generated libraries and copy them into the build/ directory
9432 * added target 'clean-intermediate-pic16' to clean intermediate
9433 files into pic16 directory
9434 * in target 'installdirs' added line to create directory pic16 in
9435 the installation path
9437 * device/include/Makefile.in (version 1.11): in target 'install'
9438 added lines to copy all header files to installation path,
9439 * in target 'installdirs' added line create directory for pic16
9440 headers in the installation path

9455 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9456 option so that it actually works. Made it specific to the z80, since
9457 the gbz80 doesn't have these kinds of I/O ports.
9459 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9461 * device/include/z180.h,

9483 Mainly changes to support compilation of the device libraries
9484 * src/pic16/device.c: stack is allocated via symbol and not
9485 via literal number. The symbol is placed in the corresponding
9486 position of the data ram
9487 * (pic16_dump_section): relocatable and absolute uninitialized
9488 data are now emitted in sorted order to reduce section naming,
9489 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9490 weren't marked as being in the access bank,
9492 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9494 Added portion of GNU PIC Library under the directory
9495 device/include/pic16 and device/lib/pic16. These files
9496 contain the declarations of SFRs for the PIC18Fxx2 devices.
9497 The directory is initialized via configure from toplevel.
9499 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9501 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

9508 2004-01-12 Borut Razem <borut.razem AT siol.net>
9510 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
9511 doc/sdccman.lyx: upper case pragmas are deprecated
9513 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9515 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

9526 * doc/sdccman.lyx: Moved and added some sections, small changes
9527 all over. Telling LaTeX to be less strict with word spacing
9528 to better keep the right margin. Changed some notes about
9529 maintainance of the ports in section 3.2.1 - is it OK like this?
9531 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9533 SDCC source changes:
9534 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9540 processor registers declared internally by the port are emitted in
9541 the translation as equates,
9542 * src/pic16/gen.c: inline code is passed unprocessed to the

9683 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9685 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9686 (default behaviour).
9688 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9690 A python script to validate compiler diagnostic messages. It can be
9691 used to verify that sdcc complains about bad c source code and
9692 gives a good location of the error.
9693 * support/valdiag/Makefile,
9694 * support/valdiag/valdiag.py,
9695 * support/valdiag/tests/*

9710 * src/common.h: added ifndef/define/endif macros
9711 around the header file.
9712 Bug reported from Jesus Calvino-Fraga
9714 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9716 * sdcc.spec: updated
9717 * device/include/Makefile.in: don't install CVS directories
9718 * device/lib/Makefile.in: added removal of CVS directories after install
9719 * doc/Makefile: fixed install, added local_icons
9720 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9721 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9722 * src/ds390/gen.c (genRightShift): fixed bug #870788
9723 * src/SDCCast.c (decorateType): fixed bug #870781
9725 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9727 PIC16 port related changes:
9728 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9729 added variable stackPos,
9731 * gen.c: genCall, assignResultValue: added support for
9732 pushing/retrieving function parameters to/from stack,
9733 genFunction,genEndFunction: setup stack frame for the
9735 genAddrOf: will be changed according to bug 863624
9737 * added files genutils.c and genutils.h which contain gen*
9738 debugged and optimised functions extracted from gen.c
9740 * glue.c: added variable 'externs' which holds extern symbols,
9741 pic16emitRegularMap: is modified to properly handle relocatable
9742 symbols under the new scheme,
9743 pic16createInterruptVect: is modified
9744 pic16printPublics: is modified to emit 'global' assembler directives,
9745 added pic16_printExterns to print extern symbols,
9746 pic16glue: initializes stack/frame pointer in the beginning of
9747 the assembly output. Temporary hack, will be corrected later,
9748 because gplink yet does not support stack and SDCC does not
9749 yet support a type of crt0.o object to create the final binary.
9751 * Removed many lines that contain 8051 legacy code.
9752 * The code is finally placed under a 'code' directive.
9753 * Added port specific options.
9755 * _process_pragma: simplified since now we do not need *special*
9756 include file to define SFR registers. But a separate header
9757 will be needed. This will be developed later.
9758 * _pic16_parseOptions: added, parses port specific options:
9759 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9760 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9761 --preplace-udata-with=
9763 * _pic16_setDefaultOptions: modified to initialize section names,
9764 but hack is temporarly out of order since it needs improvement.
9765 * _pic16_genAssemblerPreamble: configuration words are emitted by
9766 their address instead of their name. This part is incomplete and
9767 supports only the 18Fxx2 devices. Other devices will emit an error
9768 during assembly since they do not contain the same set of config
9770 * _pic16_genIVT: is modified,
9772 * pcode.c: added definitions for some hardware registers that are needed
9774 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9775 All PCI entries are updated. Now LFSR is supported.
9776 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9777 * added pic16_newpCodeOpLit2 to support instructions with
9778 two literal arguments
9779 * pic16_pCode2str: corrected code that emits assembler instructions
9780 with two literal operands and those that have an access bit modifier
9781 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9782 this fixes a bug which caused some labels to be lost, when an
9783 assembler directive was added, i.e. banksel,
9784 * pic16_FixRegisterBanking: improved logic that causes the insertion
9786 * InlineFunction: functions that are called once, are not any more
9787 inlined. This can be a port option in the future,
9789 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9791 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9792 hold the corresponding uninitialized symbols,
9793 * pic16_allocProcessorRegister: registers have explicit marked the
9795 * pic16_allocInternalRegister: registers are explicit marked as
9797 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9798 processing list, so bit registers were lost,
9801 * ralloc.h: added field 'accessBank' and original symbol operand
9802 in register definition,
9803 * removed the field isMapped from register definition,
9805 ** Several functions have been removed from various sources:
9806 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9807 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9808 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9809 pic16_assignRelocatableRegisters
9811 ** others have been introduced:
9812 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9813 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9815 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9817 * support/scripts/inc2h.pl: changed definition of BIT_AT
9818 to emit 'sbit at' instead of 'bit at'. This was a request.
9820 PIC16 port related preliminary changes:
9821 * gen.c: prefixed function popRegFromString with
9822 pic16_ and all references to it corrected
9823 * pcode.c: all pic16_pc_* hardware registers prefixed
9824 with underscore (_),
9825 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9826 * ralloc.c: newReg(): when register is REG_SFR then
9827 set address to rIdx,
9828 pic16_allocProcessorRegister(): marks register wasUsed=0
9829 pic16_writeUsedRegs(): added a call to assign processor
9830 registers via pic16_assignFixedRegisters
9832 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9834 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9835 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9836 variables in unused register banks. Also the SSEG is placed
9837 wherever there is enough space for it, and IDATA can be anywhere
9838 in internal RAM. For now compile using -Wl-Y[stack_size].
9839 The mem file is different for this option as well, since it
9840 makes no sense of talking about DSEG lenght.
9842 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9844 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9845 in certain cases, e.g. when ROM assignment, patch provided
9846 from Albert den Haan.
9848 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9989 xdata and data memory on startup. Set the environment variable
9990 SDCC_NOGENRAMCLEAR to disable this.
9991 * src/mcs51/peephole.def,
9992 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9993 (allows non-interrupt and interrupt code to safely compete for a resource
9994 without the non-interrupt code having to disable interrupts)
9996 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10002 types, not just integer types.
10003 * src/SDCCsymt.c (addSymChain): clarified error message when symbol is
10004 multiply defined with mismatching "at" address.
10006 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10008 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

10733 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10734 support for standard C idiom of memory mapped variables; for
10735 example, *((xdata int*)0x1234) = 1 is now internally equivalent

10754 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10756 Fixed bug #621531 (const & volatile confusion in the type chain).
10757 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10837 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10838 iCode properly now. Use getSize instead of nRegs since a & b
10839 aren't part of the nRegs tally.
10841 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10843 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10853 copied from genNearPointerSet()
10854 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10855 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10856 If they pop r0/r1 they must be called in the opposite order than aopOp().
10857 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10858 (resp. --stack-auto), prepared for --xstack

10871 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10872 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10873 type for bits was changed. It resulted in bit variables becoming
10874 global, which is not permitted in PIC 14 assembly output.
10876 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10878 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10880 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10882 Z80 and MCS51 linkers complaint if a public symbol is defined

10891 A few small changes that speed up the peephole optimizer.
10895 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10897 Try to make the peephole optimizer smarter by maintaining
10898 an association between the assembly source code and the
10899 iCodes that originated them. Put this information to use
10900 with a new peephole rule condition "notVolatile" so that
10901 the rules can be aggressive yet still safe.
10906 * src/mcs51/peeph.def
10908 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10912 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10913 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10914 if the left or right operand symbols have the accuse flag set.
10916 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10918 Changed the type of the result of the ! (NOT) operator to char;
10919 previously it returned the same type as the source. This allows
10920 us to eliminate all the genFloatNot functions (all of its target
10921 implementations were very buggy) since !float can use the same
10924 * src/SDCCicode.c (ast2iCode): ! returns char

10933 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10934 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10935 during interrupts. Ensure WSAVE is located at a shared bank address.
10936 2. Fixed page selection in some places
10937 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10938 the registers name strings.
10939 4. Fixed "signed / unsigned compare" compiler warnings.
10940 5. The PIC port manages its own allocation of the general purpose
10941 registers, but makes no attempt to reuse them. As a result when
10942 compiling it soon runs out of general purpose registers. Some
10943 additional code was added to the files pcode.c and device.c to walk
10944 through the function call tree and rename the registers so that they
10954 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10955 genPlus() & genMinus() when the result is the same as left or right

10961 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10963 Made bitfield a distinct type from bit so that bitfields
10964 convert as per ANSI C and bits retain their traditional
10965 boolean style behaviour. Implemented bitfield support in
10973 * src/ds390/gen.c: bit v bitfield split
10974 * src/z80/gen.c: New support for bitfields
10975 * support/regression/tests/bitfields.c: reenabled z80,
10978 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10980 Rules 246.x, 247.x relate to bitfields, the others speed up
10981 access to xdata mapped I/O devices.

10987 Cleaned up genPackBits and genUnpackBits and added two helper
10988 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10989 for literal assignments in genPackBits (thanks to Frieder for
10995 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10997 Fixed bug #748310 (pointer to function type mishandled when the
10998 function name is omitted). Also fixed a SIGSEGV when a function
10999 attribute (reentrant, etc) is used on a non-function or on a
11000 function but misplaced before the parameter list.

11029 Made the constant following the "interrupt" keyword optional. If
11030 omitted, the function will not automatically be given an entry
11031 in the interrupt vector table (similar to #pragma NOIV, but
11032 less syntacticly kludgy). The interrupt number is also now
11033 range checked. Also fixed a bug in the high order bit example

11563 added if/endif conditional macros to remove options help
11564 messages from optionsTable when a port is not configured, added
11565 support for the PIc16 port in the ports table, when executing
11566 the compiler with no port specified on command line, a default
11567 port is selected with the new macro DEFAULT_PORT which is
11568 defined in port.h, in setDefaultOptions() linkOptions is removed
11569 from initialization assignment, since now it is a set,
11570 parseCmdLine uses setParseWithComma for linkOptions, in
11571 linkEdit() linkOptions are accessed with new function indexSet()
11572 which returns the i'th item of a set variable. See SDCCset.c, in
11573 linkEdit() when calling buildCmdLine(), added linkOptions as
11574 last argument. Now users can pass arguments to gplink via the
11575 -Wl option, main() uses pic16glue() to glue up pic16 programs

11588 * src/pic16/main.c: __config directives are commented out to stop
11589 gpasm complaining and test the linkage with gplink, _linkCmd and
11590 _asmCmd changed to be more gplink and gpasm friendly
11591 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11592 produced an error when parsed, peep rule 12 is added to utilize
11593 movff, but it is commented out since the pCode does not support
11594 yet a command with 2 address arguments
11596 2003-05-18 <johan AT balder>
11598 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12659 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12661 * in /sdcc/as/mcs51/ changed these files in order to create an
12662 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12663 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12664 following files to include the previous two files: aslink.dsp,
12665 Makefile.aslink, Makefile.bcc, and Makefile.in.
12667 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12668 .adb instead of .cdb
12670 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12672 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12673 value from option --iram-size.
12675 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12677 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12680 2002-09-18 <wiml AT hhhh.org>
12682 * SDCClrange.h: exposed setFromRange() and setToRange()
12683 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12684 packRegsForAccUse() (bug 542397)
12685 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12686 multiple times and emitting the fetch operations more than once
12687 added aopGetUsesAcc() function to allow binary operators to
12688 fetch their operands in the correct order; made genMinus() emit
12689 compact code for X = LITERAL - Y
12691 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12692 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12693 sprintf() in line 1267.
12695 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12696 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12699 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12700 Changes to aslink (All the changes are marked with 'JCF'):
12702 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12705 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12706 area BSEG. Also moves, if possible, the DATA area down into the internal
12707 ram so more space is available.
12709 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12712 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12713 not bytes. Function summary() which creates a memory usage summary
12714 file with extension .mem. Reports of overlaping stack and small stack
12715 size. If the space for the stack is less than 16 bytes aslink trows a
12718 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12719 the 8051. Option 'y' for memory summary output file.
12721 Changes to sdcc (All the changes are marked with 'JCF'):
12723 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12725 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12726 overlaying area for it (uses RegBankUsed[4]).
12728 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12729 bank zero as used by default. By default aslink locates the stack
12730 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12731 the creation of the .mem file. Delegates the allocation of data area
12732 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12733 the begining of the stack area to aslink.
12735 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12736 glue() in SDCCglue.c creates an area for it.
12738 2002-09-03 Borut Razem <borut.razem AT siol.net>
12739 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12740 sdcc/src/pic/glue.c:
12741 introduced atexit() handler for teporay files removal in case of
12742 errors, assertions, ...
12744 2002-08-29 Borut Razem <borut.razem AT siol.net>
12745 * sdcc/support/cpp2/auto-host_vc_in.h:
12746 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12747 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12748 Maybe there is a similar problem with BORLANDC? It should be checked!
12750 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12751 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12752 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12753 was not executed, and the compiler (cl) launched a warning:
12754 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12756 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12757 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

12774 * sdcc/src/yacc.dsp: added
12776 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12777 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12778 and insert the version number definitions from .version
12780 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12782 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

12789 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12791 2002-08-11 Borut Razem <borut.razem AT siol.net>
12792 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12794 2002-08-10 Borut Razem <borut.razem AT siol.net>
12795 * src/SDCCmain.c (main):
12796 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12797 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12798 The consequence was that some temporary files were not removed.
12801 unification of code in functions tempfilename() and tempfile():
12802 function tempnam() is defined in Visual Studio 6.0 and .NET
12804 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12806 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12807 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12808 - removed compiler command line option /WX: Treats all warnings as errors
12809 - update a list of source files, included into the project
12811 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12812 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12813 changed project type to Generic Project so that can be correcly converted to VS.NET project
12815 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12817 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12821 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12822 added return 0 statements after assert() to make compiler happy
12824 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12825 added newline in the def file to keep MSC compiler satisfied
12827 * sdcc/src/z80/gen.c:
12828 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12829 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12830 - solved MSC error in function aopDump()
12832 * sdcc_vc.h: define PREFIX as "\\sdcc"
12834 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

13009 * sdcc/src/SDCCloop.c:
13010 Previous fix was not good. basic blocks that have "break" or "return" are
13011 not really partof a loop , but live ranges used in these blocks should
13012 be live thru the entire loop, so set partOfLoop but don't add them to
