2450 loaded with the linker search paths (-L arguments) and the libraries
2451 to be linked with the current source (-l arguments). Changes
2452 currently will affect only the pic16 port.
2453 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2454 include path the port specific paths and port specific libraries,
2455 * gplink command now contains the $3 argument,
2456 * src/pic16/device.h,

2473 Documenting changes from previous commits.
2474 * configure.in (version 1.56),
2475 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2476 when generating output files to configure the pic16 library,
2477 but now I've commented it out, since gputils aren't installed in the
2478 SF compile farm, so library won't compile
2480 * device/lib/Makefile.in (version 1.56): initially I've added in
2481 target 'all' the prerequestive 'model-pic16' so it compiled the
2482 pic16 library, but now I've commented it out for the same reasons
2484 * added targets 'model-pic16' and 'objects-pic16' to compile the
2486 * added target 'port-specific-objects-pic16' to handle the
2487 generated libraries and copy them into the build/ directory
2488 * added target 'clean-intermediate-pic16' to clean intermediate
2489 files into pic16 directory
2490 * in target 'installdirs' added line to create directory pic16 in

2783 PIC16 port related changes:
2784 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2785 added variable stackPos,
2787 * gen.c: genCall, assignResultValue: added support for
2788 pushing/retrieving function parameters to/from stack,
2789 genFunction,genEndFunction: setup stack frame for the
2791 genAddrOf: will be changed according to bug 863624
2793 * added files genutils.c and genutils.h which contain gen*
2794 debugged and optimised functions extracted from gen.c
2796 * glue.c: added variable 'externs' which holds extern symbols,
2797 pic16emitRegularMap: is modified to properly handle relocatable
2798 symbols under the new scheme,
2799 pic16createInterruptVect: is modified
2800 pic16printPublics: is modified to emit 'global' assembler directives,
2801 added pic16_printExterns to print extern symbols,
2802 pic16glue: initializes stack/frame pointer in the beginning of
2803 the assembly output. Temporary hack, will be corrected later,
2804 because gplink yet does not support stack and SDCC does not
2805 yet support a type of crt0.o object to create the final binary.
2807 * Removed many lines that contain 8051 legacy code.
2808 * The code is finally placed under a 'code' directive.
2809 * Added port specific options.
2811 * _process_pragma: simplified since now we do not need *special*
2812 include file to define SFR registers. But a separate header
2813 will be needed. This will be developed later.
2814 * _pic16_parseOptions: added, parses port specific options:
2815 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2816 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2817 --preplace-udata-with=
2819 * _pic16_setDefaultOptions: modified to initialize section names,
2820 but hack is temporarly out of order since it needs improvement.
2821 * _pic16_genAssemblerPreamble: configuration words are emitted by
2822 their address instead of their name. This part is incomplete and
2823 supports only the 18Fxx2 devices. Other devices will emit an error
2824 during assembly since they do not contain the same set of config
2826 * _pic16_genIVT: is modified,
2828 * pcode.c: added definitions for some hardware registers that are needed
2830 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2831 All PCI entries are updated. Now LFSR is supported.
2832 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2833 * added pic16_newpCodeOpLit2 to support instructions with
2834 two literal arguments
2835 * pic16_pCode2str: corrected code that emits assembler instructions
2836 with two literal operands and those that have an access bit modifier
2837 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2838 this fixes a bug which caused some labels to be lost, when an
2839 assembler directive was added, i.e. banksel,
2840 * pic16_FixRegisterBanking: improved logic that causes the insertion
2842 * InlineFunction: functions that are called once, are not any more
2843 inlined. This can be a port option in the future,
2845 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2847 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2848 hold the corresponding uninitialized symbols,
2849 * pic16_allocProcessorRegister: registers have explicit marked the
2851 * pic16_allocInternalRegister: registers are explicit marked as
2853 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2854 processing list, so bit registers were lost,
2857 * ralloc.h: added field 'accessBank' and original symbol operand
2858 in register definition,
2859 * removed the field isMapped from register definition,
2861 ** Several functions have been removed from various sources:
2862 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2863 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2864 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2865 pic16_assignRelocatableRegisters
2867 ** others have been introduced:
2868 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2869 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2871 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2873 * support/scripts/inc2h.pl: changed definition of BIT_AT
2874 to emit 'sbit at' instead of 'bit at'. This was a request.
2876 PIC16 port related preliminary changes:
2877 * gen.c: prefixed function popRegFromString with
2878 pic16_ and all references to it corrected
2879 * pcode.c: all pic16_pc_* hardware registers prefixed
2880 with underscore (_),
2881 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2882 * ralloc.c: newReg(): when register is REG_SFR then
2883 set address to rIdx,
2884 pic16_allocProcessorRegister(): marks register wasUsed=0
2885 pic16_writeUsedRegs(): added a call to assign processor
2886 registers via pic16_assignFixedRegisters
2888 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2890 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2891 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2892 variables in unused register banks. Also the SSEG is placed
2893 wherever there is enough space for it, and IDATA can be anywhere
2894 in internal RAM. For now compile using -Wl-Y[stack_size].
2895 The mem file is different for this option as well, since it
2896 makes no sense of talking about DSEG lenght.
2898 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2900 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2901 in certain cases, e.g. when ROM assignment, patch provided
2902 from Albert den Haan.
2904 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3145 * src/SDCCast.c (decorateType): disabled a transformation I added in
3146 revision 1.188 (access to fields of a structure at an absolute address);
3147 it breaks with bitfields, extern declarations, and gcse analysis.
3148 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3149 could be assigned through a pointer, so don't complain.
3150 * src/SDCCast.c (astErrors),

3770 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
3771 and restore of EA so that stack offsets to parameters are
3772 correct when using both critical and reentrant/stack-auto.

3790 support for standard C idiom of memory mapped variables; for
3791 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3792 to xdata int at 0x1234 tempvar = 1.
3793 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3794 provided by Akiya ISHIDA

3810 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3812 Fixed bug #621531 (const & volatile confusion in the type chain).
3813 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
3814 refer to the const or volatile state of the pointer itself.

3879 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
3880 pcoderegs.h, ralloc.c, ralloc.h
3881 * main.c: added top header and GPL license notice

3905 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3906 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3907 fetching of the pointer
3908 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3909 copied from genNearPointerSet()
3910 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3911 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3912 If they pop r0/r1 they must be called in the opposite order than aopOp().
3913 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3914 (resp. --stack-auto), prepared for --xstack

3925 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3927 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3928 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3929 type for bits was changed. It resulted in bit variables becoming
3930 global, which is not permitted in PIC 14 assembly output.
3932 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3934 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3947 A few small changes that speed up the peephole optimizer.
3951 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3953 Try to make the peephole optimizer smarter by maintaining
3954 an association between the assembly source code and the
3955 iCodes that originated them. Put this information to use
3956 with a new peephole rule condition "notVolatile" so that
3957 the rules can be aggressive yet still safe.
3962 * src/mcs51/peeph.def
3964 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3968 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3969 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3970 if the left or right operand symbols have the accuse flag set.
3972 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3974 Changed the type of the result of the ! (NOT) operator to char;
3975 previously it returned the same type as the source. This allows
3976 us to eliminate all the genFloatNot functions (all of its target
3977 implementations were very buggy) since !float can use the same
3980 * src/SDCCicode.c (ast2iCode): ! returns char

3989 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3990 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3991 during interrupts. Ensure WSAVE is located at a shared bank address.
3992 2. Fixed page selection in some places
3993 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3994 the registers name strings.
3995 4. Fixed "signed / unsigned compare" compiler warnings.
3996 5. The PIC port manages its own allocation of the general purpose
3997 registers, but makes no attempt to reuse them. As a result when
3998 compiling it soon runs out of general purpose registers. Some
3999 additional code was added to the files pcode.c and device.c to walk
4000 through the function call tree and rename the registers so that they
4010 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4011 genPlus() & genMinus() when the result is the same as left or right

4017 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4019 Made bitfield a distinct type from bit so that bitfields
4020 convert as per ANSI C and bits retain their traditional
4021 boolean style behaviour. Implemented bitfield support in
4029 * src/ds390/gen.c: bit v bitfield split
4030 * src/z80/gen.c: New support for bitfields
4031 * support/regression/tests/bitfields.c: reenabled z80,
4034 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4036 Rules 246.x, 247.x relate to bitfields, the others speed up
4037 access to xdata mapped I/O devices.
4039 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4041 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4043 Cleaned up genPackBits and genUnpackBits and added two helper
4044 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4045 for literal assignments in genPackBits (thanks to Frieder for
4051 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4053 Fixed bug #748310 (pointer to function type mishandled when the
4054 function name is omitted). Also fixed a SIGSEGV when a function
4055 attribute (reentrant, etc) is used on a non-function or on a
4056 function but misplaced before the parameter list.
4058 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4060 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4061 * support/Util/SDCCerr.h,
4062 * support/Util/SDCCerr.c: Added func attr misuse error msg
4064 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4066 Fixed bug #787649 by anonymous
4067 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

4083 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4085 Made the constant following the "interrupt" keyword optional. If
4086 omitted, the function will not automatically be given an entry
4087 in the interrupt vector table (similar to #pragma NOIV, but
4088 less syntacticly kludgy). The interrupt number is also now
4089 range checked. Also fixed a bug in the high order bit example

4100 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4102 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4103 * src/SDCCicode.c (operandOperation): rewritten some ops
4104 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4105 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4107 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4108 be re-activated by defining REDUCE_LITERALS)
4109 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4110 unsigned, but are signed by default
4111 * src/SDCCval.c (constVal): rearranged
4112 * src/SDCCval.c (valMod): preliminary fix
4113 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4155 constants are unsigned; added recognition of "u" flag for unsigned
4156 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4157 * src/SDCCval.c (valDiv, valMod): fixed signdness
4158 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4159 signedness of modulo, left and right shift

4618 * src/SDCCmain.c: linkOptions is changed to set *,
4619 added if/endif conditional macros to remove options help
4620 messages from optionsTable when a port is not configured, added
4621 support for the PIc16 port in the ports table, when executing
4622 the compiler with no port specified on command line, a default
4623 port is selected with the new macro DEFAULT_PORT which is
4624 defined in port.h, in setDefaultOptions() linkOptions is removed
4625 from initialization assignment, since now it is a set,
4626 parseCmdLine uses setParseWithComma for linkOptions, in
4627 linkEdit() linkOptions are accessed with new function indexSet()
4628 which returns the i'th item of a set variable. See SDCCset.c, in
4629 linkEdit() when calling buildCmdLine(), added linkOptions as
4630 last argument. Now users can pass arguments to gplink via the
4631 -Wl option, main() uses pic16glue() to glue up pic16 programs

4645 gpasm complaining and test the linkage with gplink, _linkCmd and
4646 _asmCmd changed to be more gplink and gpasm friendly
4647 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4648 produced an error when parsed, peep rule 12 is added to utilize
4649 movff, but it is commented out since the pCode does not support
4650 yet a command with 2 address arguments
4652 2003-05-18 <johan AT balder>
4654 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4681 2003-05-11 Borut Razem <borut.razem AT siol.net>
4683 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4684 the path of bin directory, so that PATH is the only env. variable, which has to be set
4685 in case of standard installation.

5706 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5707 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
5709 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
5710 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5712 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5713 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5715 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5717 * in \sdcc\as\mcs51\ changed these files in order to create an
5718 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5719 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5720 following files to include the previous two files: aslink.dsp,
5721 Makefile.aslink, Makefile.bcc, and Makefile.in.
5723 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5724 .adb instead of .cdb
5726 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5728 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5729 value from option --iram-size.
5731 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5733 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5736 2002-09-18 <wiml AT hhhh.org>
5738 * SDCClrange.h: exposed setFromRange() and setToRange()
5739 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5740 packRegsForAccUse() (bug 542397)
5741 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5742 multiple times and emitting the fetch operations more than once
5743 added aopGetUsesAcc() function to allow binary operators to
5744 fetch their operands in the correct order; made genMinus() emit
5745 compact code for X = LITERAL - Y
5747 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5748 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5749 sprintf() in line 1267.
5751 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5752 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5755 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5756 Changes to aslink (All the changes are marked with 'JCF'):
5758 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5761 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5762 area BSEG. Also moves, if possible, the DATA area down into the internal
5763 ram so more space is available.
5765 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5768 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5769 not bytes. Function summary() which creates a memory usage summary
5770 file with extension .mem. Reports of overlaping stack and small stack
5771 size. If the space for the stack is less than 16 bytes aslink trows a
5774 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5775 the 8051. Option 'y' for memory summary output file.
5777 Changes to sdcc (All the changes are marked with 'JCF'):
5779 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5781 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5782 overlaying area for it (uses RegBankUsed[4]).
5784 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5785 bank zero as used by default. By default aslink locates the stack
5786 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5787 the creation of the .mem file. Delegates the allocation of data area
5788 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5789 the begining of the stack area to aslink.
5791 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5792 glue() in SDCCglue.c creates an area for it.
5794 2002-09-03 Borut Razem <borut.razem AT siol.net>
5795 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5796 sdcc/src/pic/glue.c:
5797 introduced atexit() handler for teporay files removal in case of
5798 errors, assertions, ...
5800 2002-08-29 Borut Razem <borut.razem AT siol.net>
5801 * sdcc/support/cpp2/auto-host_vc_in.h:
5802 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5803 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5804 Maybe there is a similar problem with BORLANDC? It should be checked!
5806 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5807 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5808 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5809 was not executed, and the compiler (cl) launched a warning:
5810 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5812 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5813 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5815 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5816 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5818 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5819 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5820 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5821 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5822 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5823 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5824 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5825 - added Release configuration in VS projects
5826 - review of compiler an linker options
5827 - VC .exe files are generated in bin_vc directory, not to interfere
5828 with binaries generated from other projects (cygwin, mingw, bcc ...)
5830 * sdcc/src/yacc.dsp: added
5832 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5833 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5834 and insert the version number definitions from .version
5836 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5838 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5839 added - genarate auto-host.h using auto-host_vc_in.h as template
5842 removed from CVS, generated automatically
5844 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5845 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5847 2002-08-11 Borut Razem <borut.razem AT siol.net>
5848 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5850 2002-08-10 Borut Razem <borut.razem AT siol.net>
5851 * src/SDCCmain.c (main):
5852 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5853 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5854 The consequence was that some temporary files were not removed.
5857 unification of code in functions tempfilename() and tempfile():
5858 function tempnam() is defined in Visual Studio 6.0 and .NET
5860 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5862 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5863 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5864 - removed compiler command line option /WX: Treats all warnings as errors
5865 - update a list of source files, included into the project
5867 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5868 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5869 changed project type to Generic Project so that can be correcly converted to VS.NET project
5871 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5873 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5875 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5877 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5878 added return 0 statements after assert() to make compiler happy
5880 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5881 added newline in the def file to keep MSC compiler satisfied
5883 * sdcc/src/z80/gen.c:
5884 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5885 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5886 - solved MSC error in function aopDump()
5888 * sdcc_vc.h: define PREFIX as "\\sdcc"
5890 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5891 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5893 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5894 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5895 - Rewrote the register banking algorithm.
5896 - Added pCode live-range analysis to registers (for now, only non-used and
5897 singly-used registers optimized away)
5899 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5901 * 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.

5928 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5930 2002-03-28 Johan Knol <johan AT balder>
5932 * src/SDCCval.c: fixed bug #532436
5934 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5936 Added "char *Processor" field to the port structure.
5939 Added -p option. Allows port dependent processor to be specified.
5942 Initialized the new field char *Processor field to NULL in all ports
5945 Compiler generated registers for interrupt context saving
5946 were not getting allocated.
5948 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5951 Fixed left shift. Will promote the left side of a left shift
5952 if a) left shifting more than size of operand or b) when assigned
5953 to something size > size of left side
5955 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5957 tons of changes. Register allocation has been
5958 rewritten. Added customization for the various PICs. Flow
5959 analysis is restructured. ...
5965 Added. device.c is a PIC port hack to accomodate variations
5968 2002-03-13 Michael Hope <michaelh AT vroom>
5970 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6063 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6065 * sdcc/src/SDCCloop.c:
6066 Previous fix was not good. basic blocks that have "break" or "return" are
6067 not really partof a loop , but live ranges used in these blocks should
6068 be live thru the entire loop, so set partOfLoop but don't add them to
6071 2002-02-21 <johan AT FRIJA>
6073 * src/SDCCcse.c: fixed bug #514308
6075 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6078 Fixed BUG #519583. If a conditional block ended in a return/break
6079 statement inside a loop, it was not being considered part of the loop.
6081 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6083 2002-02-10 Karl Bongers <karl AT turbobit.com>
6086 Fixed up SDCDB debugger somewhat. Updated debugger/README
6087 with lots of comments and notes.
6089 * device/examples/test2.c:
6090 Fix bug, "red" variable not being initialized(compiler complained).
6092 * device/examples/Makefile, examples/test3.c:

6094 for use as a multiple module SDCDB test case.
6096 * sim/ucsim/cmd.src/cmdset.cc:
6097 Took out debug printfs in ucsim "next" command.
6100 Karl and Johan start ucsim XA support. Most dissassembly working,
6101 about 75% emulation done(plenty of work remaining).
6103 * sim/ucsim/z80.src:
6104 Add Z80 support to ucsim, add test-ucz80 regression test,
6105 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6141 set preprocessor defines (depending on options)
6143 * src/SDCCicode.c, src/SDCCicode.h:
6144 changes made to handle multiple sends & receives
6147 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
