2461 loaded with the linker search paths (-L arguments) and the libraries
2462 to be linked with the current source (-l arguments). Changes
2463 currently will affect only the pic16 port.
2464 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2465 include path the port specific paths and port specific libraries,
2466 * gplink command now contains the $3 argument,

2484 Documenting changes from previous commits.
2485 * configure.in (version 1.56),
2486 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2487 when generating output files to configure the pic16 library,
2488 but now I've commented it out, since gputils aren't installed in the
2489 SF compile farm, so library won't compile
2491 * device/lib/Makefile.in (version 1.56): initially I've added in
2492 target 'all' the prerequestive 'model-pic16' so it compiled the
2493 pic16 library, but now I've commented it out for the same reasons
2495 * added targets 'model-pic16' and 'objects-pic16' to compile the
2497 * added target 'port-specific-objects-pic16' to handle the
2498 generated libraries and copy them into the build/ directory
2499 * added target 'clean-intermediate-pic16' to clean intermediate
2500 files into pic16 directory
2501 * in target 'installdirs' added line to create directory pic16 in

2505 added lines to copy all header files to installation path,
2506 * in target 'installdirs' added line create directory for pic16
2507 headers in the installation path

2781 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2783 * sdcc.spec: updated
2784 * device/include/Makefile.in: don't install CVS directories
2785 * device/lib/Makefile.in: added removal of CVS directories after install
2786 * doc/Makefile: fixed install, added local_icons
2787 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2788 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2789 * src/ds390/gen.c (genRightShift): fixed bug #870788
2790 * src/SDCCast.c (decorateType): fixed bug #870781
2792 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2794 PIC16 port related changes:
2795 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2796 added variable stackPos,
2798 * gen.c: genCall, assignResultValue: added support for
2799 pushing/retrieving function parameters to/from stack,
2800 genFunction,genEndFunction: setup stack frame for the
2802 genAddrOf: will be changed according to bug 863624
2804 * added files genutils.c and genutils.h which contain gen*
2805 debugged and optimised functions extracted from gen.c
2807 * glue.c: added variable 'externs' which holds extern symbols,
2808 pic16emitRegularMap: is modified to properly handle relocatable
2809 symbols under the new scheme,
2810 pic16createInterruptVect: is modified
2811 pic16printPublics: is modified to emit 'global' assembler directives,
2812 added pic16_printExterns to print extern symbols,
2813 pic16glue: initializes stack/frame pointer in the beginning of
2814 the assembly output. Temporary hack, will be corrected later,
2815 because gplink yet does not support stack and SDCC does not
2816 yet support a type of crt0.o object to create the final binary.
2818 * Removed many lines that contain 8051 legacy code.
2819 * The code is finally placed under a 'code' directive.
2820 * Added port specific options.
2822 * _process_pragma: simplified since now we do not need *special*
2823 include file to define SFR registers. But a separate header
2824 will be needed. This will be developed later.
2825 * _pic16_parseOptions: added, parses port specific options:
2826 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2827 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2828 --preplace-udata-with=
2830 * _pic16_setDefaultOptions: modified to initialize section names,
2831 but hack is temporarly out of order since it needs improvement.
2832 * _pic16_genAssemblerPreamble: configuration words are emitted by
2833 their address instead of their name. This part is incomplete and
2834 supports only the 18Fxx2 devices. Other devices will emit an error
2835 during assembly since they do not contain the same set of config
2837 * _pic16_genIVT: is modified,
2839 * pcode.c: added definitions for some hardware registers that are needed
2841 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2842 All PCI entries are updated. Now LFSR is supported.
2843 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2844 * added pic16_newpCodeOpLit2 to support instructions with
2845 two literal arguments
2846 * pic16_pCode2str: corrected code that emits assembler instructions
2847 with two literal operands and those that have an access bit modifier
2848 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2849 this fixes a bug which caused some labels to be lost, when an
2850 assembler directive was added, i.e. banksel,
2851 * pic16_FixRegisterBanking: improved logic that causes the insertion
2853 * InlineFunction: functions that are called once, are not any more
2854 inlined. This can be a port option in the future,
2856 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2858 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2859 hold the corresponding uninitialized symbols,
2860 * pic16_allocProcessorRegister: registers have explicit marked the
2862 * pic16_allocInternalRegister: registers are explicit marked as
2864 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2865 processing list, so bit registers were lost,
2868 * ralloc.h: added field 'accessBank' and original symbol operand
2869 in register definition,
2870 * removed the field isMapped from register definition,
2872 ** Several functions have been removed from various sources:
2873 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2874 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2875 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2876 pic16_assignRelocatableRegisters
2878 ** others have been introduced:
2879 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2880 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2882 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2884 * support/scripts/inc2h.pl: changed definition of BIT_AT
2885 to emit 'sbit at' instead of 'bit at'. This was a request.
2887 PIC16 port related preliminary changes:
2888 * gen.c: prefixed function popRegFromString with
2889 pic16_ and all references to it corrected
2890 * pcode.c: all pic16_pc_* hardware registers prefixed
2891 with underscore (_),
2892 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2893 * ralloc.c: newReg(): when register is REG_SFR then
2894 set address to rIdx,
2895 pic16_allocProcessorRegister(): marks register wasUsed=0
2896 pic16_writeUsedRegs(): added a call to assign processor
2897 registers via pic16_assignFixedRegisters
2899 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2901 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2902 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2903 variables in unused register banks. Also the SSEG is placed
2904 wherever there is enough space for it, and IDATA can be anywhere
2905 in internal RAM. For now compile using -Wl-Y[stack_size].
2906 The mem file is different for this option as well, since it
2907 makes no sense of talking about DSEG lenght.
2909 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2911 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2912 in certain cases, e.g. when ROM assignment, patch provided
2913 from Albert den Haan.

3154 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3156 * src/SDCCast.c (decorateType): disabled a transformation I added in
3157 revision 1.188 (access to fields of a structure at an absolute address);
3158 it breaks with bitfields, extern declarations, and gcse analysis.
3159 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3160 could be assigned through a pointer, so don't complain.
3161 * src/SDCCast.c (astErrors),
3163 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

3801 support for standard C idiom of memory mapped variables; for
3802 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3803 to xdata int at 0x1234 tempvar = 1.
3804 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3805 provided by Akiya ISHIDA

3821 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3823 Fixed bug #621531 (const & volatile confusion in the type chain).
3824 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
3825 refer to the const or volatile state of the pointer itself.

3890 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
3891 pcoderegs.h, ralloc.c, ralloc.h
3892 * main.c: added top header and GPL license notice

3916 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3917 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3918 fetching of the pointer
3919 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3920 copied from genNearPointerSet()
3921 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3922 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3923 If they pop r0/r1 they must be called in the opposite order than aopOp().
3924 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3925 (resp. --stack-auto), prepared for --xstack

3938 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3939 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3940 type for bits was changed. It resulted in bit variables becoming
3941 global, which is not permitted in PIC 14 assembly output.
3943 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3945 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3958 A few small changes that speed up the peephole optimizer.
3962 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3964 Try to make the peephole optimizer smarter by maintaining
3965 an association between the assembly source code and the
3966 iCodes that originated them. Put this information to use
3967 with a new peephole rule condition "notVolatile" so that
3968 the rules can be aggressive yet still safe.
3973 * src/mcs51/peeph.def
3975 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3979 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3980 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3981 if the left or right operand symbols have the accuse flag set.
3983 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3985 Changed the type of the result of the ! (NOT) operator to char;
3986 previously it returned the same type as the source. This allows
3987 us to eliminate all the genFloatNot functions (all of its target
3988 implementations were very buggy) since !float can use the same
3991 * src/SDCCicode.c (ast2iCode): ! returns char

4000 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4001 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4002 during interrupts. Ensure WSAVE is located at a shared bank address.
4003 2. Fixed page selection in some places
4004 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4005 the registers name strings.
4006 4. Fixed "signed / unsigned compare" compiler warnings.
4007 5. The PIC port manages its own allocation of the general purpose
4008 registers, but makes no attempt to reuse them. As a result when
4009 compiling it soon runs out of general purpose registers. Some
4010 additional code was added to the files pcode.c and device.c to walk
4011 through the function call tree and rename the registers so that they
4021 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4022 genPlus() & genMinus() when the result is the same as left or right

4028 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4030 Made bitfield a distinct type from bit so that bitfields
4031 convert as per ANSI C and bits retain their traditional
4032 boolean style behaviour. Implemented bitfield support in
4040 * src/ds390/gen.c: bit v bitfield split
4041 * src/z80/gen.c: New support for bitfields
4042 * support/regression/tests/bitfields.c: reenabled z80,
4045 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4047 Rules 246.x, 247.x relate to bitfields, the others speed up
4048 access to xdata mapped I/O devices.
4050 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4052 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4054 Cleaned up genPackBits and genUnpackBits and added two helper
4055 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4056 for literal assignments in genPackBits (thanks to Frieder for
4062 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4064 Fixed bug #748310 (pointer to function type mishandled when the
4065 function name is omitted). Also fixed a SIGSEGV when a function
4066 attribute (reentrant, etc) is used on a non-function or on a
4067 function but misplaced before the parameter list.
4069 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4071 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4072 * support/Util/SDCCerr.h,
4073 * support/Util/SDCCerr.c: Added func attr misuse error msg

4094 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4096 Made the constant following the "interrupt" keyword optional. If
4097 omitted, the function will not automatically be given an entry
4098 in the interrupt vector table (similar to #pragma NOIV, but
4099 less syntacticly kludgy). The interrupt number is also now
4100 range checked. Also fixed a bug in the high order bit example

4114 * src/SDCCicode.c (operandOperation): rewritten some ops
4115 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4116 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4118 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4119 be re-activated by defining REDUCE_LITERALS)
4120 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4121 unsigned, but are signed by default
4122 * src/SDCCval.c (constVal): rearranged
4123 * src/SDCCval.c (valMod): preliminary fix
4124 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4166 constants are unsigned; added recognition of "u" flag for unsigned
4167 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4168 * src/SDCCval.c (valDiv, valMod): fixed signdness
4169 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4170 signedness of modulo, left and right shift

4629 * src/SDCCmain.c: linkOptions is changed to set *,
4630 added if/endif conditional macros to remove options help
4631 messages from optionsTable when a port is not configured, added
4632 support for the PIc16 port in the ports table, when executing
4633 the compiler with no port specified on command line, a default
4634 port is selected with the new macro DEFAULT_PORT which is
4635 defined in port.h, in setDefaultOptions() linkOptions is removed
4636 from initialization assignment, since now it is a set,
4637 parseCmdLine uses setParseWithComma for linkOptions, in
4638 linkEdit() linkOptions are accessed with new function indexSet()
4639 which returns the i'th item of a set variable. See SDCCset.c, in
4640 linkEdit() when calling buildCmdLine(), added linkOptions as
4641 last argument. Now users can pass arguments to gplink via the
4642 -Wl option, main() uses pic16glue() to glue up pic16 programs

4656 gpasm complaining and test the linkage with gplink, _linkCmd and
4657 _asmCmd changed to be more gplink and gpasm friendly
4658 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4659 produced an error when parsed, peep rule 12 is added to utilize
4660 movff, but it is commented out since the pCode does not support
4661 yet a command with 2 address arguments
4663 2003-05-18 <johan AT balder>
4665 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4692 2003-05-11 Borut Razem <borut.razem AT siol.net>
4694 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4695 the path of bin directory, so that PATH is the only env. variable, which has to be set

5708 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5710 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5711 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5713 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5714 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
5715 * support/regression/tests/bug-524697.c: fit mem usage into 8032
5717 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5718 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
5720 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
5721 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5723 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5724 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5726 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5728 * in \sdcc\as\mcs51\ changed these files in order to create an
5729 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5730 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5731 following files to include the previous two files: aslink.dsp,
5732 Makefile.aslink, Makefile.bcc, and Makefile.in.
5734 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5735 .adb instead of .cdb
5737 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5739 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5740 value from option --iram-size.
5742 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5744 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5747 2002-09-18 <wiml AT hhhh.org>
5749 * SDCClrange.h: exposed setFromRange() and setToRange()
5750 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5751 packRegsForAccUse() (bug 542397)
5752 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5753 multiple times and emitting the fetch operations more than once
5754 added aopGetUsesAcc() function to allow binary operators to
5755 fetch their operands in the correct order; made genMinus() emit
5756 compact code for X = LITERAL - Y
5758 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5759 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5760 sprintf() in line 1267.
5762 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5763 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5766 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5767 Changes to aslink (All the changes are marked with 'JCF'):
5769 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5772 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5773 area BSEG. Also moves, if possible, the DATA area down into the internal
5774 ram so more space is available.
5776 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5779 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5780 not bytes. Function summary() which creates a memory usage summary
5781 file with extension .mem. Reports of overlaping stack and small stack
5782 size. If the space for the stack is less than 16 bytes aslink trows a
5785 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5786 the 8051. Option 'y' for memory summary output file.
5788 Changes to sdcc (All the changes are marked with 'JCF'):
5790 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5792 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5793 overlaying area for it (uses RegBankUsed[4]).
5795 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5796 bank zero as used by default. By default aslink locates the stack
5797 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5798 the creation of the .mem file. Delegates the allocation of data area
5799 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5800 the begining of the stack area to aslink.
5802 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5803 glue() in SDCCglue.c creates an area for it.
5805 2002-09-03 Borut Razem <borut.razem AT siol.net>
5806 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5807 sdcc/src/pic/glue.c:
5808 introduced atexit() handler for teporay files removal in case of
5809 errors, assertions, ...
5811 2002-08-29 Borut Razem <borut.razem AT siol.net>
5812 * sdcc/support/cpp2/auto-host_vc_in.h:
5813 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5814 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5815 Maybe there is a similar problem with BORLANDC? It should be checked!
5817 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5818 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5819 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5820 was not executed, and the compiler (cl) launched a warning:
5821 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5823 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5824 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5826 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5827 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5829 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5830 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5831 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5832 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5833 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5834 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5835 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5836 - added Release configuration in VS projects
5837 - review of compiler an linker options
5838 - VC .exe files are generated in bin_vc directory, not to interfere
5839 with binaries generated from other projects (cygwin, mingw, bcc ...)
5841 * sdcc/src/yacc.dsp: added
5843 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5844 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5845 and insert the version number definitions from .version
5847 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5849 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5850 added - genarate auto-host.h using auto-host_vc_in.h as template
5853 removed from CVS, generated automatically
5855 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5856 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5858 2002-08-11 Borut Razem <borut.razem AT siol.net>
5859 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5861 2002-08-10 Borut Razem <borut.razem AT siol.net>
5862 * src/SDCCmain.c (main):
5863 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5864 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5865 The consequence was that some temporary files were not removed.
5868 unification of code in functions tempfilename() and tempfile():
5869 function tempnam() is defined in Visual Studio 6.0 and .NET
5871 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5873 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5874 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5875 - removed compiler command line option /WX: Treats all warnings as errors
5876 - update a list of source files, included into the project
5878 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5879 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5880 changed project type to Generic Project so that can be correcly converted to VS.NET project
5882 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5884 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5886 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5888 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5889 added return 0 statements after assert() to make compiler happy
5891 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5892 added newline in the def file to keep MSC compiler satisfied
5894 * sdcc/src/z80/gen.c:
5895 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5896 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5897 - solved MSC error in function aopDump()
5899 * sdcc_vc.h: define PREFIX as "\\sdcc"
5901 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5902 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5941 2002-03-28 Johan Knol <johan AT balder>
5943 * src/SDCCval.c: fixed bug #532436
5945 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5947 Added "char *Processor" field to the port structure.
5950 Added -p option. Allows port dependent processor to be specified.
5953 Initialized the new field char *Processor field to NULL in all ports
5956 Compiler generated registers for interrupt context saving
5957 were not getting allocated.
5959 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5962 Fixed left shift. Will promote the left side of a left shift
5963 if a) left shifting more than size of operand or b) when assigned
5964 to something size > size of left side
5966 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5968 tons of changes. Register allocation has been
5969 rewritten. Added customization for the various PICs. Flow

6074 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6076 * sdcc/src/SDCCloop.c:
6077 Previous fix was not good. basic blocks that have "break" or "return" are
6078 not really partof a loop , but live ranges used in these blocks should
6079 be live thru the entire loop, so set partOfLoop but don't add them to
6082 2002-02-21 <johan AT FRIJA>
6084 * src/SDCCcse.c: fixed bug #514308
6086 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6089 Fixed BUG #519583. If a conditional block ended in a return/break
6090 statement inside a loop, it was not being considered part of the loop.
6092 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6094 2002-02-10 Karl Bongers <karl AT turbobit.com>
6097 Fixed up SDCDB debugger somewhat. Updated debugger/README
6098 with lots of comments and notes.
6100 * device/examples/test2.c:
6101 Fix bug, "red" variable not being initialized(compiler complained).
6103 * device/examples/Makefile, examples/test3.c:

6105 for use as a multiple module SDCDB test case.
6107 * sim/ucsim/cmd.src/cmdset.cc:
6108 Took out debug printfs in ucsim "next" command.
6111 Karl and Johan start ucsim XA support. Most dissassembly working,
6112 about 75% emulation done(plenty of work remaining).
6114 * sim/ucsim/z80.src:
6115 Add Z80 support to ucsim, add test-ucz80 regression test,
6116 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6152 set preprocessor defines (depending on options)
6154 * src/SDCCicode.c, src/SDCCicode.h:
6155 changes made to handle multiple sends & receives
6158 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
