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

647 to call when a stack overflow occurs,
648 * (malloc.h): added CVS Id tag,
649 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
651 * added libc directory. The current version of LibC contains string
652 functions, ctype functions and macros and some functions of the
653 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
654 be extensively tested in the future. Standard disclaimer here.
655 Library is not automatically build yet. But one can build it by
656 invoking 'make' inside the libc directory.

667 * (pic16_storeForReturn): optimized return of 0,
668 * (genCmp): experimental code for new genCmp which uses PIC18's
669 special compare&skip instructions. Initial tests fail some times
670 with variables grater than 1 byte in size, so new code is disabled,
671 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
673 * (genCast): began a fix to optimize the casting of a bit to another
674 bit, now assigning a bitfield to another bitfield will fail, sorry,
675 * src/pic16/main.c: disabled the use of lr-support feature,
676 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
677 * added some function prototypes, added function _debugf prototype,

682 * (isBankInstruction): modified to return 0 for no banking instruction,
683 and 1 for banking instruction,

685 caused stop processing pCodes after a inline assembly block,
686 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
687 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
688 registers when it shouldn't,
689 * src/pic16/ralloc.c (allocReg): add preliminary support for
690 supporting a limited set of temporary registers,
692 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
694 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
695 genDataPointerSet): ensure assignments always copy in MSB to LSB
697 (loadRegFromAop): recognize CLRH optimization,
698 (genFunction): optimize RECEIVE iCodes in reentrant functions
700 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
702 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3611 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3613 * src/SDCCast.c: added an additional type flow in decorateType() of
3614 opposite direction, see feature request #860006; it's enabled at runtime
3615 by setting the environment variable SDCC_NEWTYPEFLOW
3616 * src/SDCCast.h: changed prototype of decorateType()
3617 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3618 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3619 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3620 see feature request #877103

3649 * src/pic/ralloc.h: applied patch from Slade Rich;
3650 added support for multiple code pages and multiple RAM banks on the
3651 PIC 14 port. The ASM files now no longer simply assume all the
3652 code / RAM are in the same page / bank. This means the linker can
3653 safely allocate code/RAM of separate ASM files to different pages/banks.
3654 * doc/sdccman.lyx: added Slade's tips
3655 * src/mcs51/peeph.def: fixed bug #880768

3697 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3699 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3700 loaded with the linker search paths (-L arguments) and the libraries
3701 to be linked with the current source (-l arguments). Changes
3702 currently will affect only the pic16 port.
3703 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3704 include path the port specific paths and port specific libraries,
3705 * gplink command now contains the $3 argument,
3706 * src/pic16/device.h,
3707 * src/pic16/device.c,: structure PIC_device is made public and
3708 renamed to PIC16_device, the same for variable Pics which is renamed

3723 Documenting changes from previous commits.
3724 * configure.in (version 1.56),
3725 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3726 when generating output files to configure the pic16 library,
3727 but now I've commented it out, since gputils aren't installed in the
3728 SF compile farm, so library won't compile
3730 * device/lib/Makefile.in (version 1.56): initially I've added in
3731 target 'all' the prerequestive 'model-pic16' so it compiled the
3732 pic16 library, but now I've commented it out for the same reasons
3734 * added targets 'model-pic16' and 'objects-pic16' to compile the
3736 * added target 'port-specific-objects-pic16' to handle the
3737 generated libraries and copy them into the build/ directory
3738 * added target 'clean-intermediate-pic16' to clean intermediate
3739 files into pic16 directory
3740 * in target 'installdirs' added line to create directory pic16 in
3741 the installation path

3744 added lines to copy all header files to installation path,
3745 * in target 'installdirs' added line create directory for pic16
3746 headers in the installation path

3762 option so that it actually works. Made it specific to the z80, since
3763 the gbz80 doesn't have these kinds of I/O ports.
3765 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3767 * device/include/z180.h,

3791 via literal number. The symbol is placed in the corresponding
3792 position of the data ram
3793 * (pic16_dump_section): relocatable and absolute uninitialized
3794 data are now emitted in sorted order to reduce section naming,
3795 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3796 weren't marked as being in the access bank,
3798 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3800 Added portion of GNU PIC Library under the directory
3801 device/include/pic16 and device/lib/pic16. These files
3802 contain the declarations of SFRs for the PIC18Fxx2 devices.
3803 The directory is initialized via configure from toplevel.

4031 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4033 PIC16 port related changes:
4034 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4035 added variable stackPos,
4037 * gen.c: genCall, assignResultValue: added support for
4038 pushing/retrieving function parameters to/from stack,
4039 genFunction,genEndFunction: setup stack frame for the
4041 genAddrOf: will be changed according to bug 863624
4043 * added files genutils.c and genutils.h which contain gen*
4044 debugged and optimised functions extracted from gen.c
4046 * glue.c: added variable 'externs' which holds extern symbols,
4047 pic16emitRegularMap: is modified to properly handle relocatable
4048 symbols under the new scheme,
4049 pic16createInterruptVect: is modified
4050 pic16printPublics: is modified to emit 'global' assembler directives,
4051 added pic16_printExterns to print extern symbols,
4052 pic16glue: initializes stack/frame pointer in the beginning of
4053 the assembly output. Temporary hack, will be corrected later,
4054 because gplink yet does not support stack and SDCC does not
4055 yet support a type of crt0.o object to create the final binary.
4057 * Removed many lines that contain 8051 legacy code.
4058 * The code is finally placed under a 'code' directive.
4059 * Added port specific options.
4061 * _process_pragma: simplified since now we do not need *special*
4062 include file to define SFR registers. But a separate header
4063 will be needed. This will be developed later.
4064 * _pic16_parseOptions: added, parses port specific options:
4065 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4066 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4067 --preplace-udata-with=
4069 * _pic16_setDefaultOptions: modified to initialize section names,
4070 but hack is temporarly out of order since it needs improvement.
4071 * _pic16_genAssemblerPreamble: configuration words are emitted by
4072 their address instead of their name. This part is incomplete and
4073 supports only the 18Fxx2 devices. Other devices will emit an error
4074 during assembly since they do not contain the same set of config
4076 * _pic16_genIVT: is modified,
4078 * pcode.c: added definitions for some hardware registers that are needed
4080 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4081 All PCI entries are updated. Now LFSR is supported.
4082 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4083 * added pic16_newpCodeOpLit2 to support instructions with
4084 two literal arguments
4085 * pic16_pCode2str: corrected code that emits assembler instructions
4086 with two literal operands and those that have an access bit modifier
4087 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4088 this fixes a bug which caused some labels to be lost, when an
4089 assembler directive was added, i.e. banksel,
4090 * pic16_FixRegisterBanking: improved logic that causes the insertion
4092 * InlineFunction: functions that are called once, are not any more
4093 inlined. This can be a port option in the future,
4095 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4097 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4098 hold the corresponding uninitialized symbols,
4099 * pic16_allocProcessorRegister: registers have explicit marked the
4101 * pic16_allocInternalRegister: registers are explicit marked as
4103 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4104 processing list, so bit registers were lost,
4107 * ralloc.h: added field 'accessBank' and original symbol operand
4108 in register definition,
4109 * removed the field isMapped from register definition,
4111 ** Several functions have been removed from various sources:
4112 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4113 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4114 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4115 pic16_assignRelocatableRegisters
4117 ** others have been introduced:
4118 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4119 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4121 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4123 * support/scripts/inc2h.pl: changed definition of BIT_AT
4124 to emit 'sbit at' instead of 'bit at'. This was a request.
4126 PIC16 port related preliminary changes:
4127 * gen.c: prefixed function popRegFromString with
4128 pic16_ and all references to it corrected
4129 * pcode.c: all pic16_pc_* hardware registers prefixed
4130 with underscore (_),
4131 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4132 * ralloc.c: newReg(): when register is REG_SFR then
4133 set address to rIdx,
4134 pic16_allocProcessorRegister(): marks register wasUsed=0
4135 pic16_writeUsedRegs(): added a call to assign processor
4136 registers via pic16_assignFixedRegisters
4138 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4140 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4141 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4142 variables in unused register banks. Also the SSEG is placed
4143 wherever there is enough space for it, and IDATA can be anywhere
4144 in internal RAM. For now compile using -Wl-Y[stack_size].
4145 The mem file is different for this option as well, since it
4146 makes no sense of talking about DSEG lenght.
4148 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4150 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4151 in certain cases, e.g. when ROM assignment, patch provided
4152 from Albert den Haan.

4393 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4395 * src/SDCCast.c (decorateType): disabled a transformation I added in
4396 revision 1.188 (access to fields of a structure at an absolute address);
4397 it breaks with bitfields, extern declarations, and gcse analysis.
4398 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4399 could be assigned through a pointer, so don't complain.
4400 * src/SDCCast.c (astErrors),

4504 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4505 uninitialized variables) for the mcs51. Set environment variable

4507 xdata initialization slightly shorter
4509 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5157 fetching of the pointer
5158 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5159 copied from genNearPointerSet()
5160 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5161 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5177 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5178 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5179 type for bits was changed. It resulted in bit variables becoming
5180 global, which is not permitted in PIC 14 assembly output.
5182 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5197 A few small changes that speed up the peephole optimizer.
5201 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5203 Try to make the peephole optimizer smarter by maintaining
5204 an association between the assembly source code and the
5205 iCodes that originated them. Put this information to use
5206 with a new peephole rule condition "notVolatile" so that
5207 the rules can be aggressive yet still safe.
5212 * src/mcs51/peeph.def
5214 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5218 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5219 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5220 if the left or right operand symbols have the accuse flag set.
5222 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5224 Changed the type of the result of the ! (NOT) operator to char;
5225 previously it returned the same type as the source. This allows
5226 us to eliminate all the genFloatNot functions (all of its target
5227 implementations were very buggy) since !float can use the same

5239 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5240 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5241 during interrupts. Ensure WSAVE is located at a shared bank address.
5242 2. Fixed page selection in some places
5243 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5244 the registers name strings.
5245 4. Fixed "signed / unsigned compare" compiler warnings.
5246 5. The PIC port manages its own allocation of the general purpose
5247 registers, but makes no attempt to reuse them. As a result when
5248 compiling it soon runs out of general purpose registers. Some
5249 additional code was added to the files pcode.c and device.c to walk
5250 through the function call tree and rename the registers so that they
5260 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5267 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5269 Made bitfield a distinct type from bit so that bitfields
5270 convert as per ANSI C and bits retain their traditional
5271 boolean style behaviour. Implemented bitfield support in
5279 * src/ds390/gen.c: bit v bitfield split
5280 * src/z80/gen.c: New support for bitfields
5281 * support/regression/tests/bitfields.c: reenabled z80,
5284 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5286 Rules 246.x, 247.x relate to bitfields, the others speed up
5287 access to xdata mapped I/O devices.
5289 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5291 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5293 Cleaned up genPackBits and genUnpackBits and added two helper
5294 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5295 for literal assignments in genPackBits (thanks to Frieder for
5301 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5303 Fixed bug #748310 (pointer to function type mishandled when the
5304 function name is omitted). Also fixed a SIGSEGV when a function
5305 attribute (reentrant, etc) is used on a non-function or on a
5306 function but misplaced before the parameter list.
5308 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5310 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5333 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5335 Made the constant following the "interrupt" keyword optional. If
5336 omitted, the function will not automatically be given an entry
5337 in the interrupt vector table (similar to #pragma NOIV, but
5338 less syntacticly kludgy). The interrupt number is also now
5339 range checked. Also fixed a bug in the high order bit example

5353 * src/SDCCicode.c (operandOperation): rewritten some ops
5354 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5355 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5357 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5358 be re-activated by defining REDUCE_LITERALS)
5359 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5360 unsigned, but are signed by default
5361 * src/SDCCval.c (constVal): rearranged
5362 * src/SDCCval.c (valMod): preliminary fix
5363 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5868 * src/SDCCmain.c: linkOptions is changed to set *,
5869 added if/endif conditional macros to remove options help
5870 messages from optionsTable when a port is not configured, added
5871 support for the PIc16 port in the ports table, when executing
5872 the compiler with no port specified on command line, a default
5873 port is selected with the new macro DEFAULT_PORT which is
5874 defined in port.h, in setDefaultOptions() linkOptions is removed
5875 from initialization assignment, since now it is a set,
5876 parseCmdLine uses setParseWithComma for linkOptions, in
5877 linkEdit() linkOptions are accessed with new function indexSet()
5878 which returns the i'th item of a set variable. See SDCCset.c, in
5879 linkEdit() when calling buildCmdLine(), added linkOptions as
5880 last argument. Now users can pass arguments to gplink via the
5881 -Wl option, main() uses pic16glue() to glue up pic16 programs

5894 * src/pic16/main.c: __config directives are commented out to stop
5895 gpasm complaining and test the linkage with gplink, _linkCmd and
5896 _asmCmd changed to be more gplink and gpasm friendly
5897 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5898 produced an error when parsed, peep rule 12 is added to utilize
5899 movff, but it is commented out since the pCode does not support
5900 yet a command with 2 address arguments
5902 2003-05-18 <johan AT balder>
5904 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5931 2003-05-11 Borut Razem <borut.razem AT siol.net>
5933 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5934 the path of bin directory, so that PATH is the only env. variable, which has to be set
5935 in case of standard installation.

6988 * SDCClrange.h: exposed setFromRange() and setToRange()
6989 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6990 packRegsForAccUse() (bug 542397)
6991 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6992 multiple times and emitting the fetch operations more than once
6993 added aopGetUsesAcc() function to allow binary operators to
6994 fetch their operands in the correct order; made genMinus() emit
6995 compact code for X = LITERAL - Y
6997 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6998 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6999 sprintf() in line 1267.
7001 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7002 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7005 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7006 Changes to aslink (All the changes are marked with 'JCF'):
7008 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7011 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7012 area BSEG. Also moves, if possible, the DATA area down into the internal
7013 ram so more space is available.
7015 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7018 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7019 not bytes. Function summary() which creates a memory usage summary
7020 file with extension .mem. Reports of overlaping stack and small stack
7021 size. If the space for the stack is less than 16 bytes aslink trows a
7024 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7025 the 8051. Option 'y' for memory summary output file.
7027 Changes to sdcc (All the changes are marked with 'JCF'):
7029 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7031 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7032 overlaying area for it (uses RegBankUsed[4]).
7034 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7035 bank zero as used by default. By default aslink locates the stack
7036 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7037 the creation of the .mem file. Delegates the allocation of data area
7038 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7039 the begining of the stack area to aslink.
7041 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7042 glue() in SDCCglue.c creates an area for it.
7044 2002-09-03 Borut Razem <borut.razem AT siol.net>
7045 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7046 sdcc/src/pic/glue.c:
7047 introduced atexit() handler for teporay files removal in case of
7048 errors, assertions, ...
7050 2002-08-29 Borut Razem <borut.razem AT siol.net>
7051 * sdcc/support/cpp2/auto-host_vc_in.h:
7052 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7053 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7054 Maybe there is a similar problem with BORLANDC? It should be checked!
7056 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7057 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7058 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7059 was not executed, and the compiler (cl) launched a warning:
7060 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7062 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7063 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7065 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7066 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7068 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7069 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7070 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7071 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7072 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7073 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7074 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7075 - added Release configuration in VS projects
7076 - review of compiler an linker options
7077 - VC .exe files are generated in bin_vc directory, not to interfere
7078 with binaries generated from other projects (cygwin, mingw, bcc ...)
7080 * sdcc/src/yacc.dsp: added
7082 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7083 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7084 and insert the version number definitions from .version
7086 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7088 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7089 added - genarate auto-host.h using auto-host_vc_in.h as template
7092 removed from CVS, generated automatically
7094 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7095 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7097 2002-08-11 Borut Razem <borut.razem AT siol.net>
7098 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7100 2002-08-10 Borut Razem <borut.razem AT siol.net>
7101 * src/SDCCmain.c (main):
7102 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7103 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7104 The consequence was that some temporary files were not removed.
7107 unification of code in functions tempfilename() and tempfile():
7108 function tempnam() is defined in Visual Studio 6.0 and .NET
7110 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7112 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7113 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7114 - removed compiler command line option /WX: Treats all warnings as errors
7115 - update a list of source files, included into the project
7117 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7118 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7119 changed project type to Generic Project so that can be correcly converted to VS.NET project
7121 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7123 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7125 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7127 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7128 added return 0 statements after assert() to make compiler happy
7130 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7131 added newline in the def file to keep MSC compiler satisfied
7133 * sdcc/src/z80/gen.c:
7134 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7135 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7136 - solved MSC error in function aopDump()
7138 * sdcc_vc.h: define PREFIX as "\\sdcc"
7140 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7141 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7144 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7145 - Rewrote the register banking algorithm.
7146 - Added pCode live-range analysis to registers (for now, only non-used and
7147 singly-used registers optimized away)
7149 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7151 * 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.

7180 2002-03-28 Johan Knol <johan AT balder>
7182 * src/SDCCval.c: fixed bug #532436
7184 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7186 Added "char *Processor" field to the port structure.
7189 Added -p option. Allows port dependent processor to be specified.
7192 Initialized the new field char *Processor field to NULL in all ports
7195 Compiler generated registers for interrupt context saving
7196 were not getting allocated.
7198 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7201 Fixed left shift. Will promote the left side of a left shift
7202 if a) left shifting more than size of operand or b) when assigned
7203 to something size > size of left side
7205 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7207 tons of changes. Register allocation has been
7208 rewritten. Added customization for the various PICs. Flow

7313 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7315 * sdcc/src/SDCCloop.c:
7316 Previous fix was not good. basic blocks that have "break" or "return" are
7317 not really partof a loop , but live ranges used in these blocks should
7318 be live thru the entire loop, so set partOfLoop but don't add them to
7321 2002-02-21 <johan AT FRIJA>
7323 * src/SDCCcse.c: fixed bug #514308
7325 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7328 Fixed BUG #519583. If a conditional block ended in a return/break
7329 statement inside a loop, it was not being considered part of the loop.
7331 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7333 2002-02-10 Karl Bongers <karl AT turbobit.com>
7336 Fixed up SDCDB debugger somewhat. Updated debugger/README
7337 with lots of comments and notes.
7339 * device/examples/test2.c:
7340 Fix bug, "red" variable not being initialized(compiler complained).
7342 * device/examples/Makefile, examples/test3.c:

7346 * sim/ucsim/cmd.src/cmdset.cc:
7347 Took out debug printfs in ucsim "next" command.
7350 Karl and Johan start ucsim XA support. Most dissassembly working,
7351 about 75% emulation done(plenty of work remaining).
7353 * sim/ucsim/z80.src:
7354 Add Z80 support to ucsim, add test-ucz80 regression test,
7355 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7391 set preprocessor defines (depending on options)
7393 * src/SDCCicode.c, src/SDCCicode.h:
7394 changes made to handle multiple sends & receives
7397 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
