217 Adding support for replacing ljmps with sjmps in jumptables
218 generated for switch statements. For now you need to set the
219 environment variable SDCC_SJMP_JUMPTABLE to enable this.

273 special compare&skip instructions. Initial tests fail some times
274 with variables grater than 1 byte in size, so new code is disabled,
275 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
277 * (genCast): began a fix to optimize the casting of a bit to another
278 bit, now assigning a bitfield to another bitfield will fail, sorry,

3304 loaded with the linker search paths (-L arguments) and the libraries
3305 to be linked with the current source (-l arguments). Changes
3306 currently will affect only the pic16 port.
3307 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3308 include path the port specific paths and port specific libraries,
3309 * gplink command now contains the $3 argument,

3327 Documenting changes from previous commits.
3328 * configure.in (version 1.56),
3329 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3330 when generating output files to configure the pic16 library,
3331 but now I've commented it out, since gputils aren't installed in the
3332 SF compile farm, so library won't compile
3334 * device/lib/Makefile.in (version 1.56): initially I've added in
3335 target 'all' the prerequestive 'model-pic16' so it compiled the
3336 pic16 library, but now I've commented it out for the same reasons
3338 * added targets 'model-pic16' and 'objects-pic16' to compile the
3340 * added target 'port-specific-objects-pic16' to handle the
3341 generated libraries and copy them into the build/ directory
3342 * added target 'clean-intermediate-pic16' to clean intermediate
3343 files into pic16 directory
3344 * in target 'installdirs' added line to create directory pic16 in

3348 added lines to copy all header files to installation path,
3349 * in target 'installdirs' added line create directory for pic16
3350 headers in the installation path

3622 Bug reported from Jesus Calvino-Fraga
3624 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3626 * sdcc.spec: updated
3627 * device/include/Makefile.in: don't install CVS directories
3628 * device/lib/Makefile.in: added removal of CVS directories after install
3629 * doc/Makefile: fixed install, added local_icons
3630 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3631 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3632 * src/ds390/gen.c (genRightShift): fixed bug #870788
3633 * src/SDCCast.c (decorateType): fixed bug #870781
3635 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3637 PIC16 port related changes:
3638 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3639 added variable stackPos,
3641 * gen.c: genCall, assignResultValue: added support for
3642 pushing/retrieving function parameters to/from stack,
3643 genFunction,genEndFunction: setup stack frame for the
3645 genAddrOf: will be changed according to bug 863624
3647 * added files genutils.c and genutils.h which contain gen*
3648 debugged and optimised functions extracted from gen.c
3650 * glue.c: added variable 'externs' which holds extern symbols,
3651 pic16emitRegularMap: is modified to properly handle relocatable
3652 symbols under the new scheme,
3653 pic16createInterruptVect: is modified
3654 pic16printPublics: is modified to emit 'global' assembler directives,
3655 added pic16_printExterns to print extern symbols,
3656 pic16glue: initializes stack/frame pointer in the beginning of
3657 the assembly output. Temporary hack, will be corrected later,
3658 because gplink yet does not support stack and SDCC does not
3659 yet support a type of crt0.o object to create the final binary.
3661 * Removed many lines that contain 8051 legacy code.
3662 * The code is finally placed under a 'code' directive.
3663 * Added port specific options.
3665 * _process_pragma: simplified since now we do not need *special*
3666 include file to define SFR registers. But a separate header
3667 will be needed. This will be developed later.
3668 * _pic16_parseOptions: added, parses port specific options:
3669 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3670 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3671 --preplace-udata-with=
3673 * _pic16_setDefaultOptions: modified to initialize section names,
3674 but hack is temporarly out of order since it needs improvement.
3675 * _pic16_genAssemblerPreamble: configuration words are emitted by
3676 their address instead of their name. This part is incomplete and
3677 supports only the 18Fxx2 devices. Other devices will emit an error
3678 during assembly since they do not contain the same set of config
3680 * _pic16_genIVT: is modified,
3682 * pcode.c: added definitions for some hardware registers that are needed
3684 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3685 All PCI entries are updated. Now LFSR is supported.
3686 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3687 * added pic16_newpCodeOpLit2 to support instructions with
3688 two literal arguments
3689 * pic16_pCode2str: corrected code that emits assembler instructions
3690 with two literal operands and those that have an access bit modifier
3691 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3692 this fixes a bug which caused some labels to be lost, when an
3693 assembler directive was added, i.e. banksel,
3694 * pic16_FixRegisterBanking: improved logic that causes the insertion
3696 * InlineFunction: functions that are called once, are not any more
3697 inlined. This can be a port option in the future,
3699 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3701 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3702 hold the corresponding uninitialized symbols,
3703 * pic16_allocProcessorRegister: registers have explicit marked the
3705 * pic16_allocInternalRegister: registers are explicit marked as
3707 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3708 processing list, so bit registers were lost,
3711 * ralloc.h: added field 'accessBank' and original symbol operand
3712 in register definition,
3713 * removed the field isMapped from register definition,
3715 ** Several functions have been removed from various sources:
3716 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3717 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3718 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3719 pic16_assignRelocatableRegisters
3721 ** others have been introduced:
3722 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3723 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3725 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3727 * support/scripts/inc2h.pl: changed definition of BIT_AT
3728 to emit 'sbit at' instead of 'bit at'. This was a request.
3730 PIC16 port related preliminary changes:
3731 * gen.c: prefixed function popRegFromString with
3732 pic16_ and all references to it corrected
3733 * pcode.c: all pic16_pc_* hardware registers prefixed
3734 with underscore (_),
3735 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3736 * ralloc.c: newReg(): when register is REG_SFR then
3737 set address to rIdx,
3738 pic16_allocProcessorRegister(): marks register wasUsed=0
3739 pic16_writeUsedRegs(): added a call to assign processor
3740 registers via pic16_assignFixedRegisters
3742 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3744 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3745 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3746 variables in unused register banks. Also the SSEG is placed
3747 wherever there is enough space for it, and IDATA can be anywhere
3748 in internal RAM. For now compile using -Wl-Y[stack_size].
3749 The mem file is different for this option as well, since it
3750 makes no sense of talking about DSEG lenght.
3752 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3754 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3755 in certain cases, e.g. when ROM assignment, patch provided
3756 from Albert den Haan.
3758 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3997 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3999 * src/SDCCast.c (decorateType): disabled a transformation I added in
4000 revision 1.188 (access to fields of a structure at an absolute address);
4001 it breaks with bitfields, extern declarations, and gcse analysis.
4002 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4003 could be assigned through a pointer, so don't complain.
4004 * src/SDCCast.c (astErrors),
4006 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4644 support for standard C idiom of memory mapped variables; for
4645 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4646 to xdata int at 0x1234 tempvar = 1.
4647 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4648 provided by Akiya ISHIDA

4664 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4666 Fixed bug #621531 (const & volatile confusion in the type chain).
4667 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4668 refer to the const or volatile state of the pointer itself.

4733 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
4734 pcoderegs.h, ralloc.c, ralloc.h
4735 * main.c: added top header and GPL license notice

4759 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4760 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4761 fetching of the pointer
4762 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4763 copied from genNearPointerSet()
4764 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4765 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4766 If they pop r0/r1 they must be called in the opposite order than aopOp().
4767 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4768 (resp. --stack-auto), prepared for --xstack

4779 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4781 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4782 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4783 type for bits was changed. It resulted in bit variables becoming
4784 global, which is not permitted in PIC 14 assembly output.
4786 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4788 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4801 A few small changes that speed up the peephole optimizer.
4805 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4807 Try to make the peephole optimizer smarter by maintaining
4808 an association between the assembly source code and the
4809 iCodes that originated them. Put this information to use
4810 with a new peephole rule condition "notVolatile" so that
4811 the rules can be aggressive yet still safe.
4816 * src/mcs51/peeph.def
4818 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4822 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4823 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4824 if the left or right operand symbols have the accuse flag set.
4826 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4828 Changed the type of the result of the ! (NOT) operator to char;
4829 previously it returned the same type as the source. This allows
4830 us to eliminate all the genFloatNot functions (all of its target
4831 implementations were very buggy) since !float can use the same

4843 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4844 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4845 during interrupts. Ensure WSAVE is located at a shared bank address.
4846 2. Fixed page selection in some places
4847 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4848 the registers name strings.
4849 4. Fixed "signed / unsigned compare" compiler warnings.
4850 5. The PIC port manages its own allocation of the general purpose
4851 registers, but makes no attempt to reuse them. As a result when
4852 compiling it soon runs out of general purpose registers. Some
4853 additional code was added to the files pcode.c and device.c to walk
4854 through the function call tree and rename the registers so that they
4864 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4865 genPlus() & genMinus() when the result is the same as left or right

4871 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4873 Made bitfield a distinct type from bit so that bitfields
4874 convert as per ANSI C and bits retain their traditional
4875 boolean style behaviour. Implemented bitfield support in
4883 * src/ds390/gen.c: bit v bitfield split
4884 * src/z80/gen.c: New support for bitfields
4885 * support/regression/tests/bitfields.c: reenabled z80,
4888 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4890 Rules 246.x, 247.x relate to bitfields, the others speed up
4891 access to xdata mapped I/O devices.
4893 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4895 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4897 Cleaned up genPackBits and genUnpackBits and added two helper
4898 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4899 for literal assignments in genPackBits (thanks to Frieder for
4905 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4907 Fixed bug #748310 (pointer to function type mishandled when the
4908 function name is omitted). Also fixed a SIGSEGV when a function
4909 attribute (reentrant, etc) is used on a non-function or on a
4910 function but misplaced before the parameter list.
4912 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4914 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4915 * support/Util/SDCCerr.h,
4916 * support/Util/SDCCerr.c: Added func attr misuse error msg

4937 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4939 Made the constant following the "interrupt" keyword optional. If
4940 omitted, the function will not automatically be given an entry
4941 in the interrupt vector table (similar to #pragma NOIV, but
4942 less syntacticly kludgy). The interrupt number is also now
4943 range checked. Also fixed a bug in the high order bit example

4956 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4957 * src/SDCCicode.c (operandOperation): rewritten some ops
4958 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4959 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4961 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4962 be re-activated by defining REDUCE_LITERALS)
4963 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4964 unsigned, but are signed by default
4965 * src/SDCCval.c (constVal): rearranged
4966 * src/SDCCval.c (valMod): preliminary fix
4967 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5009 constants are unsigned; added recognition of "u" flag for unsigned
5010 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5011 * src/SDCCval.c (valDiv, valMod): fixed signdness
5012 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

5473 added if/endif conditional macros to remove options help
5474 messages from optionsTable when a port is not configured, added
5475 support for the PIc16 port in the ports table, when executing
5476 the compiler with no port specified on command line, a default
5477 port is selected with the new macro DEFAULT_PORT which is
5478 defined in port.h, in setDefaultOptions() linkOptions is removed
5479 from initialization assignment, since now it is a set,
5480 parseCmdLine uses setParseWithComma for linkOptions, in
5481 linkEdit() linkOptions are accessed with new function indexSet()
5482 which returns the i'th item of a set variable. See SDCCset.c, in
5483 linkEdit() when calling buildCmdLine(), added linkOptions as
5484 last argument. Now users can pass arguments to gplink via the
5485 -Wl option, main() uses pic16glue() to glue up pic16 programs

5499 gpasm complaining and test the linkage with gplink, _linkCmd and
5500 _asmCmd changed to be more gplink and gpasm friendly
5501 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5502 produced an error when parsed, peep rule 12 is added to utilize
5503 movff, but it is commented out since the pCode does not support
5504 yet a command with 2 address arguments
5506 2003-05-18 <johan AT balder>
5508 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5535 2003-05-11 Borut Razem <borut.razem AT siol.net>
5537 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6549 2003-01-04 <johan AT balder>
6551 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6553 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6554 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6556 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6557 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6558 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6560 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6561 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6563 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6564 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6566 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6567 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6569 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6571 * in \sdcc\as\mcs51\ changed these files in order to create an
6572 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6573 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6574 following files to include the previous two files: aslink.dsp,
6575 Makefile.aslink, Makefile.bcc, and Makefile.in.
6577 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6578 .adb instead of .cdb
6580 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6582 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6583 value from option --iram-size.
6585 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6587 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6590 2002-09-18 <wiml AT hhhh.org>
6592 * SDCClrange.h: exposed setFromRange() and setToRange()
6593 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6594 packRegsForAccUse() (bug 542397)
6595 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6596 multiple times and emitting the fetch operations more than once
6597 added aopGetUsesAcc() function to allow binary operators to
6598 fetch their operands in the correct order; made genMinus() emit
6599 compact code for X = LITERAL - Y
6601 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6602 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6603 sprintf() in line 1267.
6605 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6606 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6609 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6610 Changes to aslink (All the changes are marked with 'JCF'):
6612 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6615 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6616 area BSEG. Also moves, if possible, the DATA area down into the internal
6617 ram so more space is available.
6619 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6622 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6623 not bytes. Function summary() which creates a memory usage summary
6624 file with extension .mem. Reports of overlaping stack and small stack
6625 size. If the space for the stack is less than 16 bytes aslink trows a
6628 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6629 the 8051. Option 'y' for memory summary output file.
6631 Changes to sdcc (All the changes are marked with 'JCF'):
6633 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6635 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6636 overlaying area for it (uses RegBankUsed[4]).
6638 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6639 bank zero as used by default. By default aslink locates the stack
6640 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6641 the creation of the .mem file. Delegates the allocation of data area
6642 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6643 the begining of the stack area to aslink.
6645 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6646 glue() in SDCCglue.c creates an area for it.
6648 2002-09-03 Borut Razem <borut.razem AT siol.net>
6649 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6650 sdcc/src/pic/glue.c:
6651 introduced atexit() handler for teporay files removal in case of
6652 errors, assertions, ...
6654 2002-08-29 Borut Razem <borut.razem AT siol.net>
6655 * sdcc/support/cpp2/auto-host_vc_in.h:
6656 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6657 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6658 Maybe there is a similar problem with BORLANDC? It should be checked!
6660 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6661 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6662 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6663 was not executed, and the compiler (cl) launched a warning:
6664 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6666 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6667 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6669 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6670 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6672 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6673 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6674 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6675 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6676 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6677 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6678 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6679 - added Release configuration in VS projects
6680 - review of compiler an linker options
6681 - VC .exe files are generated in bin_vc directory, not to interfere
6682 with binaries generated from other projects (cygwin, mingw, bcc ...)
6684 * sdcc/src/yacc.dsp: added
6686 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6687 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6688 and insert the version number definitions from .version
6690 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6692 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6693 added - genarate auto-host.h using auto-host_vc_in.h as template
6696 removed from CVS, generated automatically
6698 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6699 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6701 2002-08-11 Borut Razem <borut.razem AT siol.net>
6702 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6704 2002-08-10 Borut Razem <borut.razem AT siol.net>
6705 * src/SDCCmain.c (main):
6706 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6707 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6708 The consequence was that some temporary files were not removed.
6711 unification of code in functions tempfilename() and tempfile():
6712 function tempnam() is defined in Visual Studio 6.0 and .NET
6714 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6716 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6717 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6718 - removed compiler command line option /WX: Treats all warnings as errors
6719 - update a list of source files, included into the project
6721 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6723 changed project type to Generic Project so that can be correcly converted to VS.NET project
6725 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6727 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6729 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6731 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6732 added return 0 statements after assert() to make compiler happy
6734 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6735 added newline in the def file to keep MSC compiler satisfied
6737 * sdcc/src/z80/gen.c:
6738 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6739 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6740 - solved MSC error in function aopDump()
6742 * sdcc_vc.h: define PREFIX as "\\sdcc"
6744 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6745 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6747 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6748 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6749 - Rewrote the register banking algorithm.
6750 - Added pCode live-range analysis to registers (for now, only non-used and
6751 singly-used registers optimized away)
6753 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6755 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

6782 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6784 2002-03-28 Johan Knol <johan AT balder>
6786 * src/SDCCval.c: fixed bug #532436
6788 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6790 Added "char *Processor" field to the port structure.
6793 Added -p option. Allows port dependent processor to be specified.
6796 Initialized the new field char *Processor field to NULL in all ports
6799 Compiler generated registers for interrupt context saving
6800 were not getting allocated.
6802 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6805 Fixed left shift. Will promote the left side of a left shift
6806 if a) left shifting more than size of operand or b) when assigned
6807 to something size > size of left side
6809 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6811 tons of changes. Register allocation has been
6812 rewritten. Added customization for the various PICs. Flow
6813 analysis is restructured. ...
6819 Added. device.c is a PIC port hack to accomodate variations
6822 2002-03-13 Michael Hope <michaelh AT vroom>
6824 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6833 2002-03-04 bela <bela AT manik>
6835 * /device/include/mcs51reg.h:
6836 ds89c420 register definition update

6917 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6919 * sdcc/src/SDCCloop.c:
6920 Previous fix was not good. basic blocks that have "break" or "return" are
6921 not really partof a loop , but live ranges used in these blocks should
6922 be live thru the entire loop, so set partOfLoop but don't add them to
6925 2002-02-21 <johan AT FRIJA>
6927 * src/SDCCcse.c: fixed bug #514308
6929 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6932 Fixed BUG #519583. If a conditional block ended in a return/break
6933 statement inside a loop, it was not being considered part of the loop.
6935 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6937 2002-02-10 Karl Bongers <karl AT turbobit.com>
6940 Fixed up SDCDB debugger somewhat. Updated debugger/README
6941 with lots of comments and notes.
6943 * device/examples/test2.c:
6944 Fix bug, "red" variable not being initialized(compiler complained).
6946 * device/examples/Makefile, examples/test3.c:
6947 Add Makefile in device/examples folder, compiles test3.c
6948 for use as a multiple module SDCDB test case.
6950 * sim/ucsim/cmd.src/cmdset.cc:
6951 Took out debug printfs in ucsim "next" command.
6954 Karl and Johan start ucsim XA support. Most dissassembly working,
6955 about 75% emulation done(plenty of work remaining).
6957 * sim/ucsim/z80.src:
6958 Add Z80 support to ucsim, add test-ucz80 regression test,
6959 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6993 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
6994 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
6995 set preprocessor defines (depending on options)
6997 * src/SDCCicode.c, src/SDCCicode.h:
6998 changes made to handle multiple sends & receives
7001 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
