281 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
283 * (genCast): began a fix to optimize the casting of a bit to another
284 bit, now assigning a bitfield to another bitfield will fail, sorry,

3310 loaded with the linker search paths (-L arguments) and the libraries
3311 to be linked with the current source (-l arguments). Changes
3312 currently will affect only the pic16 port.
3313 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3314 include path the port specific paths and port specific libraries,
3315 * gplink command now contains the $3 argument,
3316 * src/pic16/device.h,

3333 Documenting changes from previous commits.
3334 * configure.in (version 1.56),
3335 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3336 when generating output files to configure the pic16 library,
3337 but now I've commented it out, since gputils aren't installed in the
3338 SF compile farm, so library won't compile
3340 * device/lib/Makefile.in (version 1.56): initially I've added in
3341 target 'all' the prerequestive 'model-pic16' so it compiled the
3342 pic16 library, but now I've commented it out for the same reasons
3344 * added targets 'model-pic16' and 'objects-pic16' to compile the
3346 * added target 'port-specific-objects-pic16' to handle the
3347 generated libraries and copy them into the build/ directory
3348 * added target 'clean-intermediate-pic16' to clean intermediate
3349 files into pic16 directory
3350 * in target 'installdirs' added line to create directory pic16 in

3354 added lines to copy all header files to installation path,
3355 * in target 'installdirs' added line create directory for pic16
3356 headers in the installation path

3622 require at least 2 bytes of storage.
3624 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3626 * src/common.h: added ifndef/define/endif macros
3627 around the header file.
3628 Bug reported from Jesus Calvino-Fraga
3630 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3632 * sdcc.spec: updated
3633 * device/include/Makefile.in: don't install CVS directories
3634 * device/lib/Makefile.in: added removal of CVS directories after install
3635 * doc/Makefile: fixed install, added local_icons
3636 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3637 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3638 * src/ds390/gen.c (genRightShift): fixed bug #870788
3639 * src/SDCCast.c (decorateType): fixed bug #870781
3641 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3643 PIC16 port related changes:
3644 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3645 added variable stackPos,
3647 * gen.c: genCall, assignResultValue: added support for
3648 pushing/retrieving function parameters to/from stack,
3649 genFunction,genEndFunction: setup stack frame for the
3651 genAddrOf: will be changed according to bug 863624
3653 * added files genutils.c and genutils.h which contain gen*
3654 debugged and optimised functions extracted from gen.c
3656 * glue.c: added variable 'externs' which holds extern symbols,
3657 pic16emitRegularMap: is modified to properly handle relocatable
3658 symbols under the new scheme,
3659 pic16createInterruptVect: is modified
3660 pic16printPublics: is modified to emit 'global' assembler directives,
3661 added pic16_printExterns to print extern symbols,
3662 pic16glue: initializes stack/frame pointer in the beginning of
3663 the assembly output. Temporary hack, will be corrected later,
3664 because gplink yet does not support stack and SDCC does not
3665 yet support a type of crt0.o object to create the final binary.
3667 * Removed many lines that contain 8051 legacy code.
3668 * The code is finally placed under a 'code' directive.
3669 * Added port specific options.
3671 * _process_pragma: simplified since now we do not need *special*
3672 include file to define SFR registers. But a separate header
3673 will be needed. This will be developed later.
3674 * _pic16_parseOptions: added, parses port specific options:
3675 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3676 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3677 --preplace-udata-with=
3679 * _pic16_setDefaultOptions: modified to initialize section names,
3680 but hack is temporarly out of order since it needs improvement.
3681 * _pic16_genAssemblerPreamble: configuration words are emitted by
3682 their address instead of their name. This part is incomplete and
3683 supports only the 18Fxx2 devices. Other devices will emit an error
3684 during assembly since they do not contain the same set of config
3686 * _pic16_genIVT: is modified,
3688 * pcode.c: added definitions for some hardware registers that are needed
3690 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3691 All PCI entries are updated. Now LFSR is supported.
3692 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3693 * added pic16_newpCodeOpLit2 to support instructions with
3694 two literal arguments
3695 * pic16_pCode2str: corrected code that emits assembler instructions
3696 with two literal operands and those that have an access bit modifier
3697 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3698 this fixes a bug which caused some labels to be lost, when an
3699 assembler directive was added, i.e. banksel,
3700 * pic16_FixRegisterBanking: improved logic that causes the insertion
3702 * InlineFunction: functions that are called once, are not any more
3703 inlined. This can be a port option in the future,
3705 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3707 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3708 hold the corresponding uninitialized symbols,
3709 * pic16_allocProcessorRegister: registers have explicit marked the
3711 * pic16_allocInternalRegister: registers are explicit marked as
3713 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3714 processing list, so bit registers were lost,
3717 * ralloc.h: added field 'accessBank' and original symbol operand
3718 in register definition,
3719 * removed the field isMapped from register definition,
3721 ** Several functions have been removed from various sources:
3722 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3723 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3724 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3725 pic16_assignRelocatableRegisters
3727 ** others have been introduced:
3728 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3729 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3731 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3733 * support/scripts/inc2h.pl: changed definition of BIT_AT
3734 to emit 'sbit at' instead of 'bit at'. This was a request.
3736 PIC16 port related preliminary changes:
3737 * gen.c: prefixed function popRegFromString with
3738 pic16_ and all references to it corrected
3739 * pcode.c: all pic16_pc_* hardware registers prefixed
3740 with underscore (_),
3741 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3742 * ralloc.c: newReg(): when register is REG_SFR then
3743 set address to rIdx,
3744 pic16_allocProcessorRegister(): marks register wasUsed=0
3745 pic16_writeUsedRegs(): added a call to assign processor
3746 registers via pic16_assignFixedRegisters
3748 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3750 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3751 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3752 variables in unused register banks. Also the SSEG is placed
3753 wherever there is enough space for it, and IDATA can be anywhere
3754 in internal RAM. For now compile using -Wl-Y[stack_size].
3755 The mem file is different for this option as well, since it
3756 makes no sense of talking about DSEG lenght.
3758 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3760 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3761 in certain cases, e.g. when ROM assignment, patch provided
3762 from Albert den Haan.
3764 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4003 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4005 * src/SDCCast.c (decorateType): disabled a transformation I added in
4006 revision 1.188 (access to fields of a structure at an absolute address);
4007 it breaks with bitfields, extern declarations, and gcse analysis.
4008 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4009 could be assigned through a pointer, so don't complain.
4010 * src/SDCCast.c (astErrors),
4012 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4650 support for standard C idiom of memory mapped variables; for
4651 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4652 to xdata int at 0x1234 tempvar = 1.
4653 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4654 provided by Akiya ISHIDA

4670 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4672 Fixed bug #621531 (const & volatile confusion in the type chain).
4673 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4674 refer to the const or volatile state of the pointer itself.

4739 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
4740 pcoderegs.h, ralloc.c, ralloc.h
4741 * main.c: added top header and GPL license notice

4765 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4766 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4767 fetching of the pointer
4768 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4769 copied from genNearPointerSet()
4770 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4771 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4772 If they pop r0/r1 they must be called in the opposite order than aopOp().
4773 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4774 (resp. --stack-auto), prepared for --xstack

4785 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4787 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4788 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4789 type for bits was changed. It resulted in bit variables becoming
4790 global, which is not permitted in PIC 14 assembly output.
4792 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4794 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4807 A few small changes that speed up the peephole optimizer.
4811 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4813 Try to make the peephole optimizer smarter by maintaining
4814 an association between the assembly source code and the
4815 iCodes that originated them. Put this information to use
4816 with a new peephole rule condition "notVolatile" so that
4817 the rules can be aggressive yet still safe.
4822 * src/mcs51/peeph.def
4824 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4828 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4829 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4830 if the left or right operand symbols have the accuse flag set.
4832 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4834 Changed the type of the result of the ! (NOT) operator to char;
4835 previously it returned the same type as the source. This allows
4836 us to eliminate all the genFloatNot functions (all of its target
4837 implementations were very buggy) since !float can use the same
4840 * src/SDCCicode.c (ast2iCode): ! returns char

4849 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4850 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4851 during interrupts. Ensure WSAVE is located at a shared bank address.
4852 2. Fixed page selection in some places
4853 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4854 the registers name strings.
4855 4. Fixed "signed / unsigned compare" compiler warnings.
4856 5. The PIC port manages its own allocation of the general purpose
4857 registers, but makes no attempt to reuse them. As a result when
4858 compiling it soon runs out of general purpose registers. Some
4859 additional code was added to the files pcode.c and device.c to walk
4860 through the function call tree and rename the registers so that they
4870 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4871 genPlus() & genMinus() when the result is the same as left or right

4877 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4879 Made bitfield a distinct type from bit so that bitfields
4880 convert as per ANSI C and bits retain their traditional
4881 boolean style behaviour. Implemented bitfield support in
4889 * src/ds390/gen.c: bit v bitfield split
4890 * src/z80/gen.c: New support for bitfields
4891 * support/regression/tests/bitfields.c: reenabled z80,
4894 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4896 Rules 246.x, 247.x relate to bitfields, the others speed up
4897 access to xdata mapped I/O devices.
4899 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4901 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4903 Cleaned up genPackBits and genUnpackBits and added two helper
4904 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4905 for literal assignments in genPackBits (thanks to Frieder for
4911 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4913 Fixed bug #748310 (pointer to function type mishandled when the
4914 function name is omitted). Also fixed a SIGSEGV when a function
4915 attribute (reentrant, etc) is used on a non-function or on a
4916 function but misplaced before the parameter list.
4918 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4920 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4921 * support/Util/SDCCerr.h,
4922 * support/Util/SDCCerr.c: Added func attr misuse error msg

4943 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4945 Made the constant following the "interrupt" keyword optional. If
4946 omitted, the function will not automatically be given an entry
4947 in the interrupt vector table (similar to #pragma NOIV, but
4948 less syntacticly kludgy). The interrupt number is also now
4949 range checked. Also fixed a bug in the high order bit example

4963 * src/SDCCicode.c (operandOperation): rewritten some ops
4964 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4965 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4967 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4968 be re-activated by defining REDUCE_LITERALS)
4969 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4970 unsigned, but are signed by default
4971 * src/SDCCval.c (constVal): rearranged
4972 * src/SDCCval.c (valMod): preliminary fix
4973 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5479 added if/endif conditional macros to remove options help
5480 messages from optionsTable when a port is not configured, added
5481 support for the PIc16 port in the ports table, when executing
5482 the compiler with no port specified on command line, a default
5483 port is selected with the new macro DEFAULT_PORT which is
5484 defined in port.h, in setDefaultOptions() linkOptions is removed
5485 from initialization assignment, since now it is a set,
5486 parseCmdLine uses setParseWithComma for linkOptions, in
5487 linkEdit() linkOptions are accessed with new function indexSet()
5488 which returns the i'th item of a set variable. See SDCCset.c, in
5489 linkEdit() when calling buildCmdLine(), added linkOptions as
5490 last argument. Now users can pass arguments to gplink via the
5491 -Wl option, main() uses pic16glue() to glue up pic16 programs

5505 gpasm complaining and test the linkage with gplink, _linkCmd and
5506 _asmCmd changed to be more gplink and gpasm friendly
5507 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5508 produced an error when parsed, peep rule 12 is added to utilize
5509 movff, but it is commented out since the pCode does not support
5510 yet a command with 2 address arguments
5512 2003-05-18 <johan AT balder>
5514 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5541 2003-05-11 Borut Razem <borut.razem AT siol.net>
5543 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6551 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6552 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6553 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6555 2003-01-04 <johan AT balder>
6557 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6559 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6560 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6562 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6563 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6564 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6566 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6567 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6569 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6570 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6572 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6573 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6575 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6577 * in \sdcc\as\mcs51\ changed these files in order to create an
6578 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6579 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6580 following files to include the previous two files: aslink.dsp,
6581 Makefile.aslink, Makefile.bcc, and Makefile.in.
6583 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6584 .adb instead of .cdb
6586 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6588 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6589 value from option --iram-size.
6591 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6593 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6596 2002-09-18 <wiml AT hhhh.org>
6598 * SDCClrange.h: exposed setFromRange() and setToRange()
6599 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6600 packRegsForAccUse() (bug 542397)
6601 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6602 multiple times and emitting the fetch operations more than once
6603 added aopGetUsesAcc() function to allow binary operators to
6604 fetch their operands in the correct order; made genMinus() emit
6605 compact code for X = LITERAL - Y
6607 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6608 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6609 sprintf() in line 1267.
6611 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6612 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6615 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6616 Changes to aslink (All the changes are marked with 'JCF'):
6618 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6621 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6622 area BSEG. Also moves, if possible, the DATA area down into the internal
6623 ram so more space is available.
6625 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6628 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6629 not bytes. Function summary() which creates a memory usage summary
6630 file with extension .mem. Reports of overlaping stack and small stack
6631 size. If the space for the stack is less than 16 bytes aslink trows a
6634 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6635 the 8051. Option 'y' for memory summary output file.
6637 Changes to sdcc (All the changes are marked with 'JCF'):
6639 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6641 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6642 overlaying area for it (uses RegBankUsed[4]).
6644 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6645 bank zero as used by default. By default aslink locates the stack
6646 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6647 the creation of the .mem file. Delegates the allocation of data area
6648 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6649 the begining of the stack area to aslink.
6651 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6652 glue() in SDCCglue.c creates an area for it.
6654 2002-09-03 Borut Razem <borut.razem AT siol.net>
6655 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6656 sdcc/src/pic/glue.c:
6657 introduced atexit() handler for teporay files removal in case of
6658 errors, assertions, ...
6660 2002-08-29 Borut Razem <borut.razem AT siol.net>
6661 * sdcc/support/cpp2/auto-host_vc_in.h:
6662 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6663 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6664 Maybe there is a similar problem with BORLANDC? It should be checked!
6666 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6667 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6668 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6669 was not executed, and the compiler (cl) launched a warning:
6670 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6672 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6673 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6675 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6676 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6678 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6679 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6680 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6681 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6682 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6683 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6684 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6685 - added Release configuration in VS projects
6686 - review of compiler an linker options
6687 - VC .exe files are generated in bin_vc directory, not to interfere
6688 with binaries generated from other projects (cygwin, mingw, bcc ...)
6690 * sdcc/src/yacc.dsp: added
6692 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6693 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6694 and insert the version number definitions from .version
6696 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6698 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6699 added - genarate auto-host.h using auto-host_vc_in.h as template
6702 removed from CVS, generated automatically
6704 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6705 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6707 2002-08-11 Borut Razem <borut.razem AT siol.net>
6708 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6710 2002-08-10 Borut Razem <borut.razem AT siol.net>
6711 * src/SDCCmain.c (main):
6712 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6713 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6714 The consequence was that some temporary files were not removed.
6717 unification of code in functions tempfilename() and tempfile():
6718 function tempnam() is defined in Visual Studio 6.0 and .NET
6720 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6722 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6723 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6724 - removed compiler command line option /WX: Treats all warnings as errors
6725 - update a list of source files, included into the project
6727 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6728 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6729 changed project type to Generic Project so that can be correcly converted to VS.NET project
6731 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6733 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6735 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6737 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6738 added return 0 statements after assert() to make compiler happy
6740 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6741 added newline in the def file to keep MSC compiler satisfied
6743 * sdcc/src/z80/gen.c:
6744 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6745 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6746 - solved MSC error in function aopDump()
6748 * sdcc_vc.h: define PREFIX as "\\sdcc"
6750 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6751 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6754 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6755 - Rewrote the register banking algorithm.
6756 - Added pCode live-range analysis to registers (for now, only non-used and
6757 singly-used registers optimized away)
6759 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6761 * 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.

6790 2002-03-28 Johan Knol <johan AT balder>
6792 * src/SDCCval.c: fixed bug #532436
6794 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6796 Added "char *Processor" field to the port structure.
6799 Added -p option. Allows port dependent processor to be specified.
6802 Initialized the new field char *Processor field to NULL in all ports
6805 Compiler generated registers for interrupt context saving
6806 were not getting allocated.
6808 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6811 Fixed left shift. Will promote the left side of a left shift
6812 if a) left shifting more than size of operand or b) when assigned
6813 to something size > size of left side
6815 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6817 tons of changes. Register allocation has been
6818 rewritten. Added customization for the various PICs. Flow
6819 analysis is restructured. ...
6825 Added. device.c is a PIC port hack to accomodate variations
6828 2002-03-13 Michael Hope <michaelh AT vroom>
6830 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6839 2002-03-04 bela <bela AT manik>
6841 * /device/include/mcs51reg.h:
6842 ds89c420 register definition update

6923 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6925 * sdcc/src/SDCCloop.c:
6926 Previous fix was not good. basic blocks that have "break" or "return" are
6927 not really partof a loop , but live ranges used in these blocks should
6928 be live thru the entire loop, so set partOfLoop but don't add them to
6931 2002-02-21 <johan AT FRIJA>
6933 * src/SDCCcse.c: fixed bug #514308
6935 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6938 Fixed BUG #519583. If a conditional block ended in a return/break
6939 statement inside a loop, it was not being considered part of the loop.
6941 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6943 2002-02-10 Karl Bongers <karl AT turbobit.com>
6946 Fixed up SDCDB debugger somewhat. Updated debugger/README
6947 with lots of comments and notes.
6949 * device/examples/test2.c:
6950 Fix bug, "red" variable not being initialized(compiler complained).
6952 * device/examples/Makefile, examples/test3.c:
6953 Add Makefile in device/examples folder, compiles test3.c
6954 for use as a multiple module SDCDB test case.
6956 * sim/ucsim/cmd.src/cmdset.cc:
6957 Took out debug printfs in ucsim "next" command.
6960 Karl and Johan start ucsim XA support. Most dissassembly working,
6961 about 75% emulation done(plenty of work remaining).
6963 * sim/ucsim/z80.src:
6964 Add Z80 support to ucsim, add test-ucz80 regression test,
6965 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6966 Notice z80 compiler fails on examples/test3.c/crc code.

6999 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7000 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7001 set preprocessor defines (depending on options)
7003 * src/SDCCicode.c, src/SDCCicode.h:
7004 changes made to handle multiple sends & receives
7007 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
