210 Adding support for replacing ljmps with sjmps in jumptables
211 generated for switch statements. For now you need to set the
212 environment variable SDCC_SJMP_JUMPTABLE to enable this.
213 Now 4 algorithms for mcs51 jumptable generation are used:
214 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

249 functions, ctype functions and macros and some functions of the
250 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
251 be extensively tested in the future. Standard disclaimer here.

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

3297 loaded with the linker search paths (-L arguments) and the libraries
3298 to be linked with the current source (-l arguments). Changes
3299 currently will affect only the pic16 port.
3300 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3301 include path the port specific paths and port specific libraries,
3302 * gplink command now contains the $3 argument,
3303 * src/pic16/device.h,
3304 * src/pic16/device.c,: structure PIC_device is made public and

3320 Documenting changes from previous commits.
3321 * configure.in (version 1.56),
3322 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3323 when generating output files to configure the pic16 library,
3324 but now I've commented it out, since gputils aren't installed in the
3325 SF compile farm, so library won't compile
3327 * device/lib/Makefile.in (version 1.56): initially I've added in
3328 target 'all' the prerequestive 'model-pic16' so it compiled the
3329 pic16 library, but now I've commented it out for the same reasons
3331 * added targets 'model-pic16' and 'objects-pic16' to compile the
3333 * added target 'port-specific-objects-pic16' to handle the
3334 generated libraries and copy them into the build/ directory
3335 * added target 'clean-intermediate-pic16' to clean intermediate
3336 files into pic16 directory
3337 * in target 'installdirs' added line to create directory pic16 in
3338 the installation path

3341 added lines to copy all header files to installation path,
3342 * in target 'installdirs' added line create directory for pic16
3343 headers in the installation path

3359 option so that it actually works. Made it specific to the z80, since
3360 the gbz80 doesn't have these kinds of I/O ports.
3362 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3623 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3624 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3625 * src/ds390/gen.c (genRightShift): fixed bug #870788
3626 * src/SDCCast.c (decorateType): fixed bug #870781
3628 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3630 PIC16 port related changes:
3631 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3632 added variable stackPos,
3634 * gen.c: genCall, assignResultValue: added support for
3635 pushing/retrieving function parameters to/from stack,
3636 genFunction,genEndFunction: setup stack frame for the
3638 genAddrOf: will be changed according to bug 863624
3640 * added files genutils.c and genutils.h which contain gen*
3641 debugged and optimised functions extracted from gen.c
3643 * glue.c: added variable 'externs' which holds extern symbols,
3644 pic16emitRegularMap: is modified to properly handle relocatable
3645 symbols under the new scheme,
3646 pic16createInterruptVect: is modified
3647 pic16printPublics: is modified to emit 'global' assembler directives,
3648 added pic16_printExterns to print extern symbols,
3649 pic16glue: initializes stack/frame pointer in the beginning of
3650 the assembly output. Temporary hack, will be corrected later,
3651 because gplink yet does not support stack and SDCC does not
3652 yet support a type of crt0.o object to create the final binary.
3654 * Removed many lines that contain 8051 legacy code.
3655 * The code is finally placed under a 'code' directive.
3656 * Added port specific options.
3658 * _process_pragma: simplified since now we do not need *special*
3659 include file to define SFR registers. But a separate header
3660 will be needed. This will be developed later.
3661 * _pic16_parseOptions: added, parses port specific options:
3662 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3663 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3664 --preplace-udata-with=
3666 * _pic16_setDefaultOptions: modified to initialize section names,
3667 but hack is temporarly out of order since it needs improvement.
3668 * _pic16_genAssemblerPreamble: configuration words are emitted by
3669 their address instead of their name. This part is incomplete and
3670 supports only the 18Fxx2 devices. Other devices will emit an error
3671 during assembly since they do not contain the same set of config
3673 * _pic16_genIVT: is modified,
3675 * pcode.c: added definitions for some hardware registers that are needed
3677 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3678 All PCI entries are updated. Now LFSR is supported.
3679 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3680 * added pic16_newpCodeOpLit2 to support instructions with
3681 two literal arguments
3682 * pic16_pCode2str: corrected code that emits assembler instructions
3683 with two literal operands and those that have an access bit modifier
3684 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3685 this fixes a bug which caused some labels to be lost, when an
3686 assembler directive was added, i.e. banksel,
3687 * pic16_FixRegisterBanking: improved logic that causes the insertion
3689 * InlineFunction: functions that are called once, are not any more
3690 inlined. This can be a port option in the future,
3692 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3694 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3695 hold the corresponding uninitialized symbols,
3696 * pic16_allocProcessorRegister: registers have explicit marked the
3698 * pic16_allocInternalRegister: registers are explicit marked as
3700 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3701 processing list, so bit registers were lost,
3704 * ralloc.h: added field 'accessBank' and original symbol operand
3705 in register definition,
3706 * removed the field isMapped from register definition,
3708 ** Several functions have been removed from various sources:
3709 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3710 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3711 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3712 pic16_assignRelocatableRegisters
3714 ** others have been introduced:
3715 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3716 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3718 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3720 * support/scripts/inc2h.pl: changed definition of BIT_AT
3721 to emit 'sbit at' instead of 'bit at'. This was a request.
3723 PIC16 port related preliminary changes:
3724 * gen.c: prefixed function popRegFromString with
3725 pic16_ and all references to it corrected
3726 * pcode.c: all pic16_pc_* hardware registers prefixed
3727 with underscore (_),
3728 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3729 * ralloc.c: newReg(): when register is REG_SFR then
3730 set address to rIdx,
3731 pic16_allocProcessorRegister(): marks register wasUsed=0
3732 pic16_writeUsedRegs(): added a call to assign processor
3733 registers via pic16_assignFixedRegisters
3735 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3737 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3738 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3739 variables in unused register banks. Also the SSEG is placed
3740 wherever there is enough space for it, and IDATA can be anywhere
3741 in internal RAM. For now compile using -Wl-Y[stack_size].
3742 The mem file is different for this option as well, since it
3743 makes no sense of talking about DSEG lenght.
3745 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3747 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3748 in certain cases, e.g. when ROM assignment, patch provided
3749 from Albert den Haan.
3751 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3990 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3992 * src/SDCCast.c (decorateType): disabled a transformation I added in
3993 revision 1.188 (access to fields of a structure at an absolute address);
3994 it breaks with bitfields, extern declarations, and gcse analysis.
3995 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3996 could be assigned through a pointer, so don't complain.
3997 * src/SDCCast.c (astErrors),
3999 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4637 support for standard C idiom of memory mapped variables; for
4638 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4639 to xdata int at 0x1234 tempvar = 1.
4640 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4641 provided by Akiya ISHIDA

4657 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4659 Fixed bug #621531 (const & volatile confusion in the type chain).
4660 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4661 refer to the const or volatile state of the pointer itself.

4752 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4753 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4754 fetching of the pointer
4755 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4756 copied from genNearPointerSet()
4757 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4758 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4759 If they pop r0/r1 they must be called in the opposite order than aopOp().

4772 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4774 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4775 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4776 type for bits was changed. It resulted in bit variables becoming
4777 global, which is not permitted in PIC 14 assembly output.
4779 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4781 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4794 A few small changes that speed up the peephole optimizer.
4798 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4800 Try to make the peephole optimizer smarter by maintaining
4801 an association between the assembly source code and the
4802 iCodes that originated them. Put this information to use
4803 with a new peephole rule condition "notVolatile" so that
4804 the rules can be aggressive yet still safe.
4809 * src/mcs51/peeph.def
4811 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4815 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4816 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4817 if the left or right operand symbols have the accuse flag set.
4819 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4821 Changed the type of the result of the ! (NOT) operator to char;
4822 previously it returned the same type as the source. This allows
4823 us to eliminate all the genFloatNot functions (all of its target
4824 implementations were very buggy) since !float can use the same
4827 * src/SDCCicode.c (ast2iCode): ! returns char

4836 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4837 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4838 during interrupts. Ensure WSAVE is located at a shared bank address.
4839 2. Fixed page selection in some places
4840 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4841 the registers name strings.
4842 4. Fixed "signed / unsigned compare" compiler warnings.
4843 5. The PIC port manages its own allocation of the general purpose
4844 registers, but makes no attempt to reuse them. As a result when
4845 compiling it soon runs out of general purpose registers. Some
4846 additional code was added to the files pcode.c and device.c to walk
4847 through the function call tree and rename the registers so that they
4857 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4858 genPlus() & genMinus() when the result is the same as left or right

4864 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4866 Made bitfield a distinct type from bit so that bitfields
4867 convert as per ANSI C and bits retain their traditional
4868 boolean style behaviour. Implemented bitfield support in
4876 * src/ds390/gen.c: bit v bitfield split
4877 * src/z80/gen.c: New support for bitfields
4878 * support/regression/tests/bitfields.c: reenabled z80,
4881 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4883 Rules 246.x, 247.x relate to bitfields, the others speed up
4884 access to xdata mapped I/O devices.
4886 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4888 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4890 Cleaned up genPackBits and genUnpackBits and added two helper
4891 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4892 for literal assignments in genPackBits (thanks to Frieder for
4898 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4900 Fixed bug #748310 (pointer to function type mishandled when the
4901 function name is omitted). Also fixed a SIGSEGV when a function
4902 attribute (reentrant, etc) is used on a non-function or on a
4903 function but misplaced before the parameter list.
4905 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4907 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4908 * support/Util/SDCCerr.h,
4909 * support/Util/SDCCerr.c: Added func attr misuse error msg

4930 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4932 Made the constant following the "interrupt" keyword optional. If
4933 omitted, the function will not automatically be given an entry
4934 in the interrupt vector table (similar to #pragma NOIV, but
4935 less syntacticly kludgy). The interrupt number is also now
4936 range checked. Also fixed a bug in the high order bit example

4950 * src/SDCCicode.c (operandOperation): rewritten some ops
4951 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4952 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4954 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4955 be re-activated by defining REDUCE_LITERALS)
4956 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4957 unsigned, but are signed by default
4958 * src/SDCCval.c (constVal): rearranged
4959 * src/SDCCval.c (valMod): preliminary fix
4960 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5002 constants are unsigned; added recognition of "u" flag for unsigned
5003 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5004 * src/SDCCval.c (valDiv, valMod): fixed signdness
5005 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5006 signedness of modulo, left and right shift

5465 * src/SDCCmain.c: linkOptions is changed to set *,
5466 added if/endif conditional macros to remove options help
5467 messages from optionsTable when a port is not configured, added
5468 support for the PIc16 port in the ports table, when executing
5469 the compiler with no port specified on command line, a default
5470 port is selected with the new macro DEFAULT_PORT which is
5471 defined in port.h, in setDefaultOptions() linkOptions is removed
5472 from initialization assignment, since now it is a set,
5473 parseCmdLine uses setParseWithComma for linkOptions, in
5474 linkEdit() linkOptions are accessed with new function indexSet()
5475 which returns the i'th item of a set variable. See SDCCset.c, in
5476 linkEdit() when calling buildCmdLine(), added linkOptions as
5477 last argument. Now users can pass arguments to gplink via the
5478 -Wl option, main() uses pic16glue() to glue up pic16 programs

5490 * src/pic16/glue.c: commented out some error producing lines
5491 * src/pic16/main.c: __config directives are commented out to stop
5492 gpasm complaining and test the linkage with gplink, _linkCmd and
5493 _asmCmd changed to be more gplink and gpasm friendly
5494 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5495 produced an error when parsed, peep rule 12 is added to utilize
5496 movff, but it is commented out since the pCode does not support
5497 yet a command with 2 address arguments
5499 2003-05-18 <johan AT balder>
5501 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5528 2003-05-11 Borut Razem <borut.razem AT siol.net>
5530 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5531 the path of bin directory, so that PATH is the only env. variable, which has to be set

6547 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6549 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6550 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6551 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6553 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6554 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6556 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6557 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6559 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6560 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6562 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6564 * in \sdcc\as\mcs51\ changed these files in order to create an
6565 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6566 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6567 following files to include the previous two files: aslink.dsp,
6568 Makefile.aslink, Makefile.bcc, and Makefile.in.
6570 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6571 .adb instead of .cdb
6573 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6575 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6576 value from option --iram-size.
6578 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6580 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6583 2002-09-18 <wiml AT hhhh.org>
6585 * SDCClrange.h: exposed setFromRange() and setToRange()
6586 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6587 packRegsForAccUse() (bug 542397)
6588 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6589 multiple times and emitting the fetch operations more than once
6590 added aopGetUsesAcc() function to allow binary operators to
6591 fetch their operands in the correct order; made genMinus() emit
6592 compact code for X = LITERAL - Y
6594 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6595 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6596 sprintf() in line 1267.
6598 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6599 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6602 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6603 Changes to aslink (All the changes are marked with 'JCF'):
6605 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6608 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6609 area BSEG. Also moves, if possible, the DATA area down into the internal
6610 ram so more space is available.
6612 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6615 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6616 not bytes. Function summary() which creates a memory usage summary
6617 file with extension .mem. Reports of overlaping stack and small stack
6618 size. If the space for the stack is less than 16 bytes aslink trows a
6621 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6622 the 8051. Option 'y' for memory summary output file.
6624 Changes to sdcc (All the changes are marked with 'JCF'):
6626 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6628 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6629 overlaying area for it (uses RegBankUsed[4]).
6631 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6632 bank zero as used by default. By default aslink locates the stack
6633 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6634 the creation of the .mem file. Delegates the allocation of data area
6635 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6636 the begining of the stack area to aslink.
6638 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6639 glue() in SDCCglue.c creates an area for it.
6641 2002-09-03 Borut Razem <borut.razem AT siol.net>
6642 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6643 sdcc/src/pic/glue.c:
6644 introduced atexit() handler for teporay files removal in case of
6645 errors, assertions, ...
6647 2002-08-29 Borut Razem <borut.razem AT siol.net>
6648 * sdcc/support/cpp2/auto-host_vc_in.h:
6649 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6650 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6651 Maybe there is a similar problem with BORLANDC? It should be checked!
6653 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6654 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6655 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6656 was not executed, and the compiler (cl) launched a warning:
6657 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6659 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6660 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6662 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6663 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6665 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6666 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6667 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6668 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6669 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6670 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6671 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6672 - added Release configuration in VS projects
6673 - review of compiler an linker options
6674 - VC .exe files are generated in bin_vc directory, not to interfere
6675 with binaries generated from other projects (cygwin, mingw, bcc ...)
6677 * sdcc/src/yacc.dsp: added
6679 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6680 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6681 and insert the version number definitions from .version
6683 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6685 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6686 added - genarate auto-host.h using auto-host_vc_in.h as template
6689 removed from CVS, generated automatically
6691 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6692 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6694 2002-08-11 Borut Razem <borut.razem AT siol.net>
6695 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6697 2002-08-10 Borut Razem <borut.razem AT siol.net>
6698 * src/SDCCmain.c (main):
6699 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6700 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6701 The consequence was that some temporary files were not removed.
6704 unification of code in functions tempfilename() and tempfile():
6705 function tempnam() is defined in Visual Studio 6.0 and .NET
6707 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6709 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6710 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6711 - removed compiler command line option /WX: Treats all warnings as errors
6712 - update a list of source files, included into the project
6714 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6715 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6716 changed project type to Generic Project so that can be correcly converted to VS.NET project
6718 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6720 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6722 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6724 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6725 added return 0 statements after assert() to make compiler happy
6727 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6728 added newline in the def file to keep MSC compiler satisfied
6730 * sdcc/src/z80/gen.c:
6731 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6732 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6733 - solved MSC error in function aopDump()
6735 * sdcc_vc.h: define PREFIX as "\\sdcc"
6737 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6738 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6741 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6742 - Rewrote the register banking algorithm.
6743 - Added pCode live-range analysis to registers (for now, only non-used and
6744 singly-used registers optimized away)
6746 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6748 * 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.

6775 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6777 2002-03-28 Johan Knol <johan AT balder>
6779 * src/SDCCval.c: fixed bug #532436
6781 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6783 Added "char *Processor" field to the port structure.
6786 Added -p option. Allows port dependent processor to be specified.
6789 Initialized the new field char *Processor field to NULL in all ports
6792 Compiler generated registers for interrupt context saving
6793 were not getting allocated.
6795 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6798 Fixed left shift. Will promote the left side of a left shift
6799 if a) left shifting more than size of operand or b) when assigned
6800 to something size > size of left side
6802 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6804 tons of changes. Register allocation has been
6805 rewritten. Added customization for the various PICs. Flow
6806 analysis is restructured. ...
6812 Added. device.c is a PIC port hack to accomodate variations
6815 2002-03-13 Michael Hope <michaelh AT vroom>
6817 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6910 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6912 * sdcc/src/SDCCloop.c:
6913 Previous fix was not good. basic blocks that have "break" or "return" are
6914 not really partof a loop , but live ranges used in these blocks should
6915 be live thru the entire loop, so set partOfLoop but don't add them to
6918 2002-02-21 <johan AT FRIJA>
6920 * src/SDCCcse.c: fixed bug #514308
6922 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6925 Fixed BUG #519583. If a conditional block ended in a return/break
6926 statement inside a loop, it was not being considered part of the loop.
6928 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6930 2002-02-10 Karl Bongers <karl AT turbobit.com>
6933 Fixed up SDCDB debugger somewhat. Updated debugger/README
6934 with lots of comments and notes.
6936 * device/examples/test2.c:
6937 Fix bug, "red" variable not being initialized(compiler complained).
6939 * device/examples/Makefile, examples/test3.c:

6941 for use as a multiple module SDCDB test case.
6943 * sim/ucsim/cmd.src/cmdset.cc:
6944 Took out debug printfs in ucsim "next" command.
6947 Karl and Johan start ucsim XA support. Most dissassembly working,
6948 about 75% emulation done(plenty of work remaining).
6950 * sim/ucsim/z80.src:
6951 Add Z80 support to ucsim, add test-ucz80 regression test,
6952 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6988 set preprocessor defines (depending on options)
6990 * src/SDCCicode.c, src/SDCCicode.h:
6991 changes made to handle multiple sends & receives
6994 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
