2612 loaded with the linker search paths (-L arguments) and the libraries
2613 to be linked with the current source (-l arguments). Changes
2614 currently will affect only the pic16 port.
2615 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2616 include path the port specific paths and port specific libraries,
2617 * gplink command now contains the $3 argument,
2618 * src/pic16/device.h,
2619 * src/pic16/device.c,: structure PIC_device is made public and

2635 Documenting changes from previous commits.
2636 * configure.in (version 1.56),
2637 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2638 when generating output files to configure the pic16 library,
2639 but now I've commented it out, since gputils aren't installed in the
2640 SF compile farm, so library won't compile
2642 * device/lib/Makefile.in (version 1.56): initially I've added in
2643 target 'all' the prerequestive 'model-pic16' so it compiled the
2644 pic16 library, but now I've commented it out for the same reasons
2646 * added targets 'model-pic16' and 'objects-pic16' to compile the
2648 * added target 'port-specific-objects-pic16' to handle the
2649 generated libraries and copy them into the build/ directory
2650 * added target 'clean-intermediate-pic16' to clean intermediate
2651 files into pic16 directory
2652 * in target 'installdirs' added line to create directory pic16 in
2653 the installation path

2656 added lines to copy all header files to installation path,
2657 * in target 'installdirs' added line create directory for pic16
2658 headers in the installation path

2674 option so that it actually works. Made it specific to the z80, since
2675 the gbz80 doesn't have these kinds of I/O ports.
2677 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2679 * device/include/z180.h,

2706 data are now emitted in sorted order to reduce section naming,
2707 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2708 weren't marked as being in the access bank,

2712 Added portion of GNU PIC Library under the directory
2713 device/include/pic16 and device/lib/pic16. These files
2714 contain the declarations of SFRs for the PIC18Fxx2 devices.
2715 The directory is initialized via configure from toplevel.

2746 to better keep the right margin. Changed some notes about
2747 maintainance of the ports in section 3.2.1 - is it OK like this?
2749 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2758 processor registers declared internally by the port are emitted in
2759 the translation as equates,
2760 * src/pic16/gen.c: inline code is passed unprocessed to the

2901 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2903 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2904 (default behaviour).
2906 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2908 A python script to validate compiler diagnostic messages. It can be
2909 used to verify that sdcc complains about bad c source code and
2910 gives a good location of the error.
2911 * support/valdiag/Makefile,
2912 * support/valdiag/valdiag.py,
2913 * support/valdiag/tests/*

2928 * src/common.h: added ifndef/define/endif macros
2929 around the header file.
2930 Bug reported from Jesus Calvino-Fraga
2932 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2934 * sdcc.spec: updated
2935 * device/include/Makefile.in: don't install CVS directories
2936 * device/lib/Makefile.in: added removal of CVS directories after install
2937 * doc/Makefile: fixed install, added local_icons
2938 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2939 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2940 * src/ds390/gen.c (genRightShift): fixed bug #870788
2941 * src/SDCCast.c (decorateType): fixed bug #870781
2943 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2945 PIC16 port related changes:
2946 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2947 added variable stackPos,
2949 * gen.c: genCall, assignResultValue: added support for
2950 pushing/retrieving function parameters to/from stack,
2951 genFunction,genEndFunction: setup stack frame for the
2953 genAddrOf: will be changed according to bug 863624
2955 * added files genutils.c and genutils.h which contain gen*
2956 debugged and optimised functions extracted from gen.c
2958 * glue.c: added variable 'externs' which holds extern symbols,
2959 pic16emitRegularMap: is modified to properly handle relocatable
2960 symbols under the new scheme,
2961 pic16createInterruptVect: is modified
2962 pic16printPublics: is modified to emit 'global' assembler directives,
2963 added pic16_printExterns to print extern symbols,
2964 pic16glue: initializes stack/frame pointer in the beginning of
2965 the assembly output. Temporary hack, will be corrected later,
2966 because gplink yet does not support stack and SDCC does not
2967 yet support a type of crt0.o object to create the final binary.
2969 * Removed many lines that contain 8051 legacy code.
2970 * The code is finally placed under a 'code' directive.
2971 * Added port specific options.
2973 * _process_pragma: simplified since now we do not need *special*
2974 include file to define SFR registers. But a separate header
2975 will be needed. This will be developed later.
2976 * _pic16_parseOptions: added, parses port specific options:
2977 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2978 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2979 --preplace-udata-with=
2981 * _pic16_setDefaultOptions: modified to initialize section names,
2982 but hack is temporarly out of order since it needs improvement.
2983 * _pic16_genAssemblerPreamble: configuration words are emitted by
2984 their address instead of their name. This part is incomplete and
2985 supports only the 18Fxx2 devices. Other devices will emit an error
2986 during assembly since they do not contain the same set of config
2988 * _pic16_genIVT: is modified,
2990 * pcode.c: added definitions for some hardware registers that are needed
2992 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2993 All PCI entries are updated. Now LFSR is supported.
2994 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2995 * added pic16_newpCodeOpLit2 to support instructions with
2996 two literal arguments
2997 * pic16_pCode2str: corrected code that emits assembler instructions
2998 with two literal operands and those that have an access bit modifier
2999 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3000 this fixes a bug which caused some labels to be lost, when an
3001 assembler directive was added, i.e. banksel,
3002 * pic16_FixRegisterBanking: improved logic that causes the insertion
3004 * InlineFunction: functions that are called once, are not any more
3005 inlined. This can be a port option in the future,
3007 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3009 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3010 hold the corresponding uninitialized symbols,
3011 * pic16_allocProcessorRegister: registers have explicit marked the
3013 * pic16_allocInternalRegister: registers are explicit marked as
3015 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3016 processing list, so bit registers were lost,
3019 * ralloc.h: added field 'accessBank' and original symbol operand
3020 in register definition,
3021 * removed the field isMapped from register definition,
3023 ** Several functions have been removed from various sources:
3024 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3025 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3026 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3027 pic16_assignRelocatableRegisters
3029 ** others have been introduced:
3030 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3031 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3033 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3035 * support/scripts/inc2h.pl: changed definition of BIT_AT
3036 to emit 'sbit at' instead of 'bit at'. This was a request.
3038 PIC16 port related preliminary changes:
3039 * gen.c: prefixed function popRegFromString with
3040 pic16_ and all references to it corrected
3041 * pcode.c: all pic16_pc_* hardware registers prefixed
3042 with underscore (_),
3043 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3044 * ralloc.c: newReg(): when register is REG_SFR then
3045 set address to rIdx,
3046 pic16_allocProcessorRegister(): marks register wasUsed=0
3047 pic16_writeUsedRegs(): added a call to assign processor
3048 registers via pic16_assignFixedRegisters
3050 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3052 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3053 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3054 variables in unused register banks. Also the SSEG is placed
3055 wherever there is enough space for it, and IDATA can be anywhere
3056 in internal RAM. For now compile using -Wl-Y[stack_size].
3057 The mem file is different for this option as well, since it
3058 makes no sense of talking about DSEG lenght.
3060 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3062 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3063 in certain cases, e.g. when ROM assignment, patch provided
3064 from Albert den Haan.
3066 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3207 xdata and data memory on startup. Set the environment variable
3208 SDCC_NOGENRAMCLEAR to disable this.
3209 * src/mcs51/peephole.def,
3210 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3211 (allows non-interrupt and interrupt code to safely compete for a resource
3212 without the non-interrupt code having to disable interrupts)
3214 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3952 support for standard C idiom of memory mapped variables; for
3953 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3954 to xdata int at 0x1234 tempvar = 1.
3955 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3956 provided by Akiya ISHIDA

3972 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3974 Fixed bug #621531 (const & volatile confusion in the type chain).
3975 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4055 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4056 iCode properly now. Use getSize instead of nRegs since a & b
4057 aren't part of the nRegs tally.
4059 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4061 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

4067 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4068 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4069 fetching of the pointer
4070 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4071 copied from genNearPointerSet()
4072 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4073 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4074 If they pop r0/r1 they must be called in the opposite order than aopOp().
4075 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4076 (resp. --stack-auto), prepared for --xstack

4087 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4089 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4090 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4091 type for bits was changed. It resulted in bit variables becoming
4092 global, which is not permitted in PIC 14 assembly output.
4094 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4096 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4107 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4109 A few small changes that speed up the peephole optimizer.
4113 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4115 Try to make the peephole optimizer smarter by maintaining
4116 an association between the assembly source code and the
4117 iCodes that originated them. Put this information to use
4118 with a new peephole rule condition "notVolatile" so that
4119 the rules can be aggressive yet still safe.
4124 * src/mcs51/peeph.def
4126 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4130 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4131 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4132 if the left or right operand symbols have the accuse flag set.
4134 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4136 Changed the type of the result of the ! (NOT) operator to char;
4137 previously it returned the same type as the source. This allows
4138 us to eliminate all the genFloatNot functions (all of its target
4139 implementations were very buggy) since !float can use the same
4142 * src/SDCCicode.c (ast2iCode): ! returns char
4143 * src/mcs51/gen.c (genNot, genNotFloat),
4144 * src/ds390/gen.c (genNot, genNotFloat),
4145 * src/z80/gen.c (genNot, genNotFloat),
4146 * src/pic/gen.c (genNot, genNotFloat),

4149 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4151 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4152 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4153 during interrupts. Ensure WSAVE is located at a shared bank address.
4154 2. Fixed page selection in some places
4155 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4156 the registers name strings.
4157 4. Fixed "signed / unsigned compare" compiler warnings.
4158 5. The PIC port manages its own allocation of the general purpose
4159 registers, but makes no attempt to reuse them. As a result when
4160 compiling it soon runs out of general purpose registers. Some
4161 additional code was added to the files pcode.c and device.c to walk
4162 through the function call tree and rename the registers so that they
4172 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4173 genPlus() & genMinus() when the result is the same as left or right
4175 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4179 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4181 Made bitfield a distinct type from bit so that bitfields
4182 convert as per ANSI C and bits retain their traditional
4183 boolean style behaviour. Implemented bitfield support in
4191 * src/ds390/gen.c: bit v bitfield split
4192 * src/z80/gen.c: New support for bitfields
4193 * support/regression/tests/bitfields.c: reenabled z80,
4196 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4198 Rules 246.x, 247.x relate to bitfields, the others speed up
4199 access to xdata mapped I/O devices.
4201 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4203 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4205 Cleaned up genPackBits and genUnpackBits and added two helper
4206 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4207 for literal assignments in genPackBits (thanks to Frieder for
4213 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4215 Fixed bug #748310 (pointer to function type mishandled when the
4216 function name is omitted). Also fixed a SIGSEGV when a function
4217 attribute (reentrant, etc) is used on a non-function or on a
4218 function but misplaced before the parameter list.
4220 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4222 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4223 * support/Util/SDCCerr.h,
4224 * support/Util/SDCCerr.c: Added func attr misuse error msg
4226 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4228 Fixed bug #787649 by anonymous
4229 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
4230 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
4232 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4245 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4247 Made the constant following the "interrupt" keyword optional. If
4248 omitted, the function will not automatically be given an entry
4249 in the interrupt vector table (similar to #pragma NOIV, but
4250 less syntacticly kludgy). The interrupt number is also now
4251 range checked. Also fixed a bug in the high order bit example
4258 * support/Util/SDCCerr.c
4259 * support/Util/SDCCerr.h

4780 * src/SDCCmain.c: linkOptions is changed to set *,
4781 added if/endif conditional macros to remove options help
4782 messages from optionsTable when a port is not configured, added
4783 support for the PIc16 port in the ports table, when executing
4784 the compiler with no port specified on command line, a default
4785 port is selected with the new macro DEFAULT_PORT which is
4786 defined in port.h, in setDefaultOptions() linkOptions is removed
4787 from initialization assignment, since now it is a set,
4788 parseCmdLine uses setParseWithComma for linkOptions, in
4789 linkEdit() linkOptions are accessed with new function indexSet()
4790 which returns the i'th item of a set variable. See SDCCset.c, in
4791 linkEdit() when calling buildCmdLine(), added linkOptions as
4792 last argument. Now users can pass arguments to gplink via the
4793 -Wl option, main() uses pic16glue() to glue up pic16 programs

4806 * src/pic16/main.c: __config directives are commented out to stop
4807 gpasm complaining and test the linkage with gplink, _linkCmd and
4808 _asmCmd changed to be more gplink and gpasm friendly
4809 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4810 produced an error when parsed, peep rule 12 is added to utilize
4811 movff, but it is commented out since the pCode does not support
4812 yet a command with 2 address arguments

5855 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5857 2003-01-04 <johan AT balder>
5859 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5861 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5862 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5864 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5872 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5874 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5875 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5877 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5879 * in \sdcc\as\mcs51\ changed these files in order to create an
5880 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5881 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5882 following files to include the previous two files: aslink.dsp,
5883 Makefile.aslink, Makefile.bcc, and Makefile.in.
5885 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5886 .adb instead of .cdb
5888 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5890 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5891 value from option --iram-size.
5893 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5895 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5898 2002-09-18 <wiml AT hhhh.org>
5900 * SDCClrange.h: exposed setFromRange() and setToRange()
5901 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5902 packRegsForAccUse() (bug 542397)
5903 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5904 multiple times and emitting the fetch operations more than once
5905 added aopGetUsesAcc() function to allow binary operators to
5906 fetch their operands in the correct order; made genMinus() emit
5907 compact code for X = LITERAL - Y
5909 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5910 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5911 sprintf() in line 1267.
5913 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5914 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5917 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5918 Changes to aslink (All the changes are marked with 'JCF'):
5920 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5923 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5924 area BSEG. Also moves, if possible, the DATA area down into the internal
5925 ram so more space is available.
5927 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5930 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5931 not bytes. Function summary() which creates a memory usage summary
5932 file with extension .mem. Reports of overlaping stack and small stack
5933 size. If the space for the stack is less than 16 bytes aslink trows a
5936 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5937 the 8051. Option 'y' for memory summary output file.
5939 Changes to sdcc (All the changes are marked with 'JCF'):
5941 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5943 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5944 overlaying area for it (uses RegBankUsed[4]).
5946 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5947 bank zero as used by default. By default aslink locates the stack
5948 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5949 the creation of the .mem file. Delegates the allocation of data area
5950 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5951 the begining of the stack area to aslink.
5953 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5954 glue() in SDCCglue.c creates an area for it.
5956 2002-09-03 Borut Razem <borut.razem AT siol.net>
5957 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5958 sdcc/src/pic/glue.c:
5959 introduced atexit() handler for teporay files removal in case of
5960 errors, assertions, ...
5962 2002-08-29 Borut Razem <borut.razem AT siol.net>
5963 * sdcc/support/cpp2/auto-host_vc_in.h:
5964 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5965 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5966 Maybe there is a similar problem with BORLANDC? It should be checked!
5968 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5969 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5970 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5971 was not executed, and the compiler (cl) launched a warning:
5972 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5974 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5975 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5977 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5978 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5980 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5981 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5982 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5983 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5984 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5985 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5986 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5987 - added Release configuration in VS projects
5988 - review of compiler an linker options
5989 - VC .exe files are generated in bin_vc directory, not to interfere
5990 with binaries generated from other projects (cygwin, mingw, bcc ...)
5992 * sdcc/src/yacc.dsp: added
5994 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5995 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5996 and insert the version number definitions from .version
5998 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6000 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6001 added - genarate auto-host.h using auto-host_vc_in.h as template
6004 removed from CVS, generated automatically
6006 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6007 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6009 2002-08-11 Borut Razem <borut.razem AT siol.net>
6010 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6012 2002-08-10 Borut Razem <borut.razem AT siol.net>
6013 * src/SDCCmain.c (main):
6014 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6015 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6016 The consequence was that some temporary files were not removed.
6019 unification of code in functions tempfilename() and tempfile():
6020 function tempnam() is defined in Visual Studio 6.0 and .NET
6022 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6024 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6025 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6026 - removed compiler command line option /WX: Treats all warnings as errors
6027 - update a list of source files, included into the project
6029 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6030 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6031 changed project type to Generic Project so that can be correcly converted to VS.NET project
6033 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6035 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6037 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6039 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6040 added return 0 statements after assert() to make compiler happy
6042 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6043 added newline in the def file to keep MSC compiler satisfied
6045 * sdcc/src/z80/gen.c:
6046 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6047 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6048 - solved MSC error in function aopDump()
6050 * sdcc_vc.h: define PREFIX as "\\sdcc"
6052 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6053 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6055 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6056 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6057 - Rewrote the register banking algorithm.
6058 - Added pCode live-range analysis to registers (for now, only non-used and
6059 singly-used registers optimized away)
6061 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6063 * 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.
6065 2002-05-10 Scott Dattalo <scott AT dattalo.com>

6088 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6090 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6092 2002-03-28 Johan Knol <johan AT balder>
6094 * src/SDCCval.c: fixed bug #532436
6096 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6098 Added "char *Processor" field to the port structure.
6101 Added -p option. Allows port dependent processor to be specified.
6104 Initialized the new field char *Processor field to NULL in all ports
6107 Compiler generated registers for interrupt context saving
6108 were not getting allocated.
6110 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6113 Fixed left shift. Will promote the left side of a left shift
6114 if a) left shifting more than size of operand or b) when assigned
6115 to something size > size of left side
6117 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6119 tons of changes. Register allocation has been
6120 rewritten. Added customization for the various PICs. Flow
6121 analysis is restructured. ...
6127 Added. device.c is a PIC port hack to accomodate variations
6130 2002-03-13 Michael Hope <michaelh AT vroom>
6132 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6134 2002-03-04 johanknol <johanknol AT manik>
6136 * /src/SDCCval.c: fixed
6138 const unsigned char arr[][2] = { { 0, 1 } };
6139 t18.c:1: error: Initializer element is not constant
6141 2002-03-04 bela <bela AT manik>
6143 * /device/include/mcs51reg.h:
6144 ds89c420 register definition update
6146 2002-03-03 <johan AT FRIJA>
6148 * support/Util/SDCCerr.c: did something, but don't no why anymore
6150 * support/regression/tests/bug-524691.c: made it a little less shy
