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

655 * added libc directory. The current version of LibC contains string
656 functions, ctype functions and macros and some functions of the
657 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
658 be extensively tested in the future. Standard disclaimer here.
659 Library is not automatically build yet. But one can build it by

672 * (genCmp): experimental code for new genCmp which uses PIC18's
673 special compare&skip instructions. Initial tests fail some times
674 with variables grater than 1 byte in size, so new code is disabled,
675 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
677 * (genCast): began a fix to optimize the casting of a bit to another
678 bit, now assigning a bitfield to another bitfield will fail, sorry,

3615 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3617 * src/SDCCast.c: added an additional type flow in decorateType() of
3618 opposite direction, see feature request #860006; it's enabled at runtime
3619 by setting the environment variable SDCC_NEWTYPEFLOW
3620 * src/SDCCast.h: changed prototype of decorateType()
3621 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3622 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3623 'char' to 'int' can be omitted, if both operands are 'unsigned char';

3654 added support for multiple code pages and multiple RAM banks on the
3655 PIC 14 port. The ASM files now no longer simply assume all the
3656 code / RAM are in the same page / bank. This means the linker can
3657 safely allocate code/RAM of separate ASM files to different pages/banks.
3658 * doc/sdccman.lyx: added Slade's tips
3659 * src/mcs51/peeph.def: fixed bug #880768

3701 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3703 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3704 loaded with the linker search paths (-L arguments) and the libraries
3705 to be linked with the current source (-l arguments). Changes
3706 currently will affect only the pic16 port.
3707 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3708 include path the port specific paths and port specific libraries,
3709 * gplink command now contains the $3 argument,
3710 * src/pic16/device.h,
3711 * src/pic16/device.c,: structure PIC_device is made public and
3712 renamed to PIC16_device, the same for variable Pics which is renamed

3727 Documenting changes from previous commits.
3728 * configure.in (version 1.56),
3729 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3730 when generating output files to configure the pic16 library,
3731 but now I've commented it out, since gputils aren't installed in the
3732 SF compile farm, so library won't compile
3734 * device/lib/Makefile.in (version 1.56): initially I've added in
3735 target 'all' the prerequestive 'model-pic16' so it compiled the
3736 pic16 library, but now I've commented it out for the same reasons
3738 * added targets 'model-pic16' and 'objects-pic16' to compile the
3740 * added target 'port-specific-objects-pic16' to handle the
3741 generated libraries and copy them into the build/ directory
3742 * added target 'clean-intermediate-pic16' to clean intermediate
3743 files into pic16 directory
3744 * in target 'installdirs' added line to create directory pic16 in
3745 the installation path
3747 * device/include/Makefile.in (version 1.11): in target 'install'
3748 added lines to copy all header files to installation path,
3749 * in target 'installdirs' added line create directory for pic16
3750 headers in the installation path

3765 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3766 option so that it actually works. Made it specific to the z80, since
3767 the gbz80 doesn't have these kinds of I/O ports.
3769 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3771 * device/include/z180.h,

3795 via literal number. The symbol is placed in the corresponding
3796 position of the data ram
3797 * (pic16_dump_section): relocatable and absolute uninitialized
3798 data are now emitted in sorted order to reduce section naming,
3799 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3800 weren't marked as being in the access bank,
3802 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3804 Added portion of GNU PIC Library under the directory
3805 device/include/pic16 and device/lib/pic16. These files
3806 contain the declarations of SFRs for the PIC18Fxx2 devices.

3837 all over. Telling LaTeX to be less strict with word spacing
3838 to better keep the right margin. Changed some notes about
3839 maintainance of the ports in section 3.2.1 - is it OK like this?

4035 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4037 PIC16 port related changes:
4038 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4039 added variable stackPos,
4041 * gen.c: genCall, assignResultValue: added support for
4042 pushing/retrieving function parameters to/from stack,
4043 genFunction,genEndFunction: setup stack frame for the
4045 genAddrOf: will be changed according to bug 863624
4047 * added files genutils.c and genutils.h which contain gen*
4048 debugged and optimised functions extracted from gen.c
4050 * glue.c: added variable 'externs' which holds extern symbols,
4051 pic16emitRegularMap: is modified to properly handle relocatable
4052 symbols under the new scheme,
4053 pic16createInterruptVect: is modified
4054 pic16printPublics: is modified to emit 'global' assembler directives,
4055 added pic16_printExterns to print extern symbols,
4056 pic16glue: initializes stack/frame pointer in the beginning of
4057 the assembly output. Temporary hack, will be corrected later,
4058 because gplink yet does not support stack and SDCC does not
4059 yet support a type of crt0.o object to create the final binary.
4061 * Removed many lines that contain 8051 legacy code.
4062 * The code is finally placed under a 'code' directive.
4063 * Added port specific options.
4065 * _process_pragma: simplified since now we do not need *special*
4066 include file to define SFR registers. But a separate header
4067 will be needed. This will be developed later.
4068 * _pic16_parseOptions: added, parses port specific options:
4069 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4070 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4071 --preplace-udata-with=
4073 * _pic16_setDefaultOptions: modified to initialize section names,
4074 but hack is temporarly out of order since it needs improvement.
4075 * _pic16_genAssemblerPreamble: configuration words are emitted by
4076 their address instead of their name. This part is incomplete and
4077 supports only the 18Fxx2 devices. Other devices will emit an error
4078 during assembly since they do not contain the same set of config
4080 * _pic16_genIVT: is modified,
4082 * pcode.c: added definitions for some hardware registers that are needed
4084 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4085 All PCI entries are updated. Now LFSR is supported.
4086 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4087 * added pic16_newpCodeOpLit2 to support instructions with
4088 two literal arguments
4089 * pic16_pCode2str: corrected code that emits assembler instructions
4090 with two literal operands and those that have an access bit modifier
4091 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4092 this fixes a bug which caused some labels to be lost, when an
4093 assembler directive was added, i.e. banksel,
4094 * pic16_FixRegisterBanking: improved logic that causes the insertion
4096 * InlineFunction: functions that are called once, are not any more
4097 inlined. This can be a port option in the future,
4099 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4101 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4102 hold the corresponding uninitialized symbols,
4103 * pic16_allocProcessorRegister: registers have explicit marked the
4105 * pic16_allocInternalRegister: registers are explicit marked as
4107 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4108 processing list, so bit registers were lost,
4111 * ralloc.h: added field 'accessBank' and original symbol operand
4112 in register definition,
4113 * removed the field isMapped from register definition,
4115 ** Several functions have been removed from various sources:
4116 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4117 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4118 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4119 pic16_assignRelocatableRegisters
4121 ** others have been introduced:
4122 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4123 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4125 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4127 * support/scripts/inc2h.pl: changed definition of BIT_AT
4128 to emit 'sbit at' instead of 'bit at'. This was a request.
4130 PIC16 port related preliminary changes:
4131 * gen.c: prefixed function popRegFromString with
4132 pic16_ and all references to it corrected
4133 * pcode.c: all pic16_pc_* hardware registers prefixed
4134 with underscore (_),
4135 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4136 * ralloc.c: newReg(): when register is REG_SFR then
4137 set address to rIdx,
4138 pic16_allocProcessorRegister(): marks register wasUsed=0
4139 pic16_writeUsedRegs(): added a call to assign processor
4140 registers via pic16_assignFixedRegisters
4142 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4144 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4145 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4146 variables in unused register banks. Also the SSEG is placed
4147 wherever there is enough space for it, and IDATA can be anywhere
4148 in internal RAM. For now compile using -Wl-Y[stack_size].
4149 The mem file is different for this option as well, since it
4150 makes no sense of talking about DSEG lenght.
4152 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4154 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4155 in certain cases, e.g. when ROM assignment, patch provided
4156 from Albert den Haan.

4397 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4399 * src/SDCCast.c (decorateType): disabled a transformation I added in
4400 revision 1.188 (access to fields of a structure at an absolute address);
4401 it breaks with bitfields, extern declarations, and gcse analysis.
4402 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4403 could be assigned through a pointer, so don't complain.

4508 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4509 uninitialized variables) for the mcs51. Set environment variable
4510 SDCC_GENRAMCLEAR to test.
4511 xdata initialization slightly shorter
4513 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5181 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5182 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5183 type for bits was changed. It resulted in bit variables becoming

5201 A few small changes that speed up the peephole optimizer.
5205 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5207 Try to make the peephole optimizer smarter by maintaining
5208 an association between the assembly source code and the
5209 iCodes that originated them. Put this information to use
5210 with a new peephole rule condition "notVolatile" so that
5211 the rules can be aggressive yet still safe.
5216 * src/mcs51/peeph.def
5218 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5222 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5223 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5224 if the left or right operand symbols have the accuse flag set.
5226 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5228 Changed the type of the result of the ! (NOT) operator to char;
5229 previously it returned the same type as the source. This allows
5230 us to eliminate all the genFloatNot functions (all of its target
5231 implementations were very buggy) since !float can use the same

5243 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5244 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5245 during interrupts. Ensure WSAVE is located at a shared bank address.
5246 2. Fixed page selection in some places
5247 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5248 the registers name strings.
5249 4. Fixed "signed / unsigned compare" compiler warnings.
5250 5. The PIC port manages its own allocation of the general purpose
5251 registers, but makes no attempt to reuse them. As a result when
5252 compiling it soon runs out of general purpose registers. Some
5253 additional code was added to the files pcode.c and device.c to walk
5254 through the function call tree and rename the registers so that they
5264 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5271 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5273 Made bitfield a distinct type from bit so that bitfields
5274 convert as per ANSI C and bits retain their traditional
5275 boolean style behaviour. Implemented bitfield support in
5283 * src/ds390/gen.c: bit v bitfield split
5284 * src/z80/gen.c: New support for bitfields
5285 * support/regression/tests/bitfields.c: reenabled z80,
5288 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5290 Rules 246.x, 247.x relate to bitfields, the others speed up
5291 access to xdata mapped I/O devices.
5293 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5295 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5297 Cleaned up genPackBits and genUnpackBits and added two helper
5298 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5299 for literal assignments in genPackBits (thanks to Frieder for
5305 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5307 Fixed bug #748310 (pointer to function type mishandled when the
5308 function name is omitted). Also fixed a SIGSEGV when a function
5309 attribute (reentrant, etc) is used on a non-function or on a
5310 function but misplaced before the parameter list.
5312 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5314 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5315 * support/Util/SDCCerr.h,

5337 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5339 Made the constant following the "interrupt" keyword optional. If
5340 omitted, the function will not automatically be given an entry
5341 in the interrupt vector table (similar to #pragma NOIV, but
5342 less syntacticly kludgy). The interrupt number is also now
5343 range checked. Also fixed a bug in the high order bit example

5357 * src/SDCCicode.c (operandOperation): rewritten some ops
5358 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5359 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5361 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5362 be re-activated by defining REDUCE_LITERALS)
5363 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5364 unsigned, but are signed by default
5365 * src/SDCCval.c (constVal): rearranged
5366 * src/SDCCval.c (valMod): preliminary fix
5367 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5872 * src/SDCCmain.c: linkOptions is changed to set *,
5873 added if/endif conditional macros to remove options help
5874 messages from optionsTable when a port is not configured, added
5875 support for the PIc16 port in the ports table, when executing
5876 the compiler with no port specified on command line, a default
5877 port is selected with the new macro DEFAULT_PORT which is
5878 defined in port.h, in setDefaultOptions() linkOptions is removed
5879 from initialization assignment, since now it is a set,
5880 parseCmdLine uses setParseWithComma for linkOptions, in
5881 linkEdit() linkOptions are accessed with new function indexSet()
5882 which returns the i'th item of a set variable. See SDCCset.c, in
5883 linkEdit() when calling buildCmdLine(), added linkOptions as
5884 last argument. Now users can pass arguments to gplink via the
5885 -Wl option, main() uses pic16glue() to glue up pic16 programs

5899 gpasm complaining and test the linkage with gplink, _linkCmd and
5900 _asmCmd changed to be more gplink and gpasm friendly
5901 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5902 produced an error when parsed, peep rule 12 is added to utilize
5903 movff, but it is commented out since the pCode does not support
5904 yet a command with 2 address arguments
5906 2003-05-18 <johan AT balder>
5908 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5935 2003-05-11 Borut Razem <borut.razem AT siol.net>
5937 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5938 the path of bin directory, so that PATH is the only env. variable, which has to be set
5939 in case of standard installation.

6987 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6990 2002-09-18 <wiml AT hhhh.org>
6992 * SDCClrange.h: exposed setFromRange() and setToRange()
6993 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6994 packRegsForAccUse() (bug 542397)
6995 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6996 multiple times and emitting the fetch operations more than once
6997 added aopGetUsesAcc() function to allow binary operators to
6998 fetch their operands in the correct order; made genMinus() emit
6999 compact code for X = LITERAL - Y
7001 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7002 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7003 sprintf() in line 1267.
7005 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7006 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7009 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7010 Changes to aslink (All the changes are marked with 'JCF'):
7012 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7015 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7016 area BSEG. Also moves, if possible, the DATA area down into the internal
7017 ram so more space is available.
7019 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7022 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7023 not bytes. Function summary() which creates a memory usage summary
7024 file with extension .mem. Reports of overlaping stack and small stack
7025 size. If the space for the stack is less than 16 bytes aslink trows a
7028 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7029 the 8051. Option 'y' for memory summary output file.
7031 Changes to sdcc (All the changes are marked with 'JCF'):
7033 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7035 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7036 overlaying area for it (uses RegBankUsed[4]).
7038 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7039 bank zero as used by default. By default aslink locates the stack
7040 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7041 the creation of the .mem file. Delegates the allocation of data area
7042 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7043 the begining of the stack area to aslink.
7045 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7046 glue() in SDCCglue.c creates an area for it.
7048 2002-09-03 Borut Razem <borut.razem AT siol.net>
7049 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7050 sdcc/src/pic/glue.c:
7051 introduced atexit() handler for teporay files removal in case of
7052 errors, assertions, ...
7054 2002-08-29 Borut Razem <borut.razem AT siol.net>
7055 * sdcc/support/cpp2/auto-host_vc_in.h:
7056 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7057 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7058 Maybe there is a similar problem with BORLANDC? It should be checked!
7060 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7061 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7062 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7063 was not executed, and the compiler (cl) launched a warning:
7064 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7066 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7067 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7069 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7070 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7072 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7073 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7074 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7075 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7076 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7077 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7078 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7079 - added Release configuration in VS projects
7080 - review of compiler an linker options
7081 - VC .exe files are generated in bin_vc directory, not to interfere
7082 with binaries generated from other projects (cygwin, mingw, bcc ...)
7084 * sdcc/src/yacc.dsp: added
7086 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7087 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7088 and insert the version number definitions from .version
7090 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7092 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7093 added - genarate auto-host.h using auto-host_vc_in.h as template
7096 removed from CVS, generated automatically
7098 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7099 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7101 2002-08-11 Borut Razem <borut.razem AT siol.net>
7102 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7104 2002-08-10 Borut Razem <borut.razem AT siol.net>
7105 * src/SDCCmain.c (main):
7106 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7107 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7108 The consequence was that some temporary files were not removed.
7111 unification of code in functions tempfilename() and tempfile():
7112 function tempnam() is defined in Visual Studio 6.0 and .NET
7114 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7116 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7117 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7118 - removed compiler command line option /WX: Treats all warnings as errors
7119 - update a list of source files, included into the project
7121 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7122 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7123 changed project type to Generic Project so that can be correcly converted to VS.NET project
7125 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7127 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7129 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7131 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7132 added return 0 statements after assert() to make compiler happy
7134 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7135 added newline in the def file to keep MSC compiler satisfied
7137 * sdcc/src/z80/gen.c:
7138 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7139 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7140 - solved MSC error in function aopDump()
7142 * sdcc_vc.h: define PREFIX as "\\sdcc"
7144 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7145 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7148 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7149 - Rewrote the register banking algorithm.
7150 - Added pCode live-range analysis to registers (for now, only non-used and
7151 singly-used registers optimized away)
7153 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7155 * 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.

7184 2002-03-28 Johan Knol <johan AT balder>
7186 * src/SDCCval.c: fixed bug #532436
7188 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7190 Added "char *Processor" field to the port structure.
7193 Added -p option. Allows port dependent processor to be specified.
7196 Initialized the new field char *Processor field to NULL in all ports
7199 Compiler generated registers for interrupt context saving
7200 were not getting allocated.
7202 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7205 Fixed left shift. Will promote the left side of a left shift
7206 if a) left shifting more than size of operand or b) when assigned
7207 to something size > size of left side
7209 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7211 tons of changes. Register allocation has been
7212 rewritten. Added customization for the various PICs. Flow

7317 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7319 * sdcc/src/SDCCloop.c:
7320 Previous fix was not good. basic blocks that have "break" or "return" are
7321 not really partof a loop , but live ranges used in these blocks should
7322 be live thru the entire loop, so set partOfLoop but don't add them to
7325 2002-02-21 <johan AT FRIJA>
7327 * src/SDCCcse.c: fixed bug #514308
7329 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7332 Fixed BUG #519583. If a conditional block ended in a return/break
7333 statement inside a loop, it was not being considered part of the loop.
7335 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7337 2002-02-10 Karl Bongers <karl AT turbobit.com>
7340 Fixed up SDCDB debugger somewhat. Updated debugger/README
7341 with lots of comments and notes.
7343 * device/examples/test2.c:
7344 Fix bug, "red" variable not being initialized(compiler complained).

7395 set preprocessor defines (depending on options)
7397 * src/SDCCicode.c, src/SDCCicode.h:
7398 changes made to handle multiple sends & receives
7401 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
