548 Adding support for replacing ljmps with sjmps in jumptables
549 generated for switch statements. For now you need to set the
550 environment variable SDCC_SJMP_JUMPTABLE to enable this.
551 Now 4 algorithms for mcs51 jumptable generation are used:
552 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
553 addresses loaded pc-relative for up to 112 cases and stack-pushing
554 target addresses loaded with offset from dptr for up to 256 cases.

582 to call when a stack overflow occurs,
583 * (malloc.h): added CVS Id tag,
584 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
586 * added libc directory. The current version of LibC contains string
587 functions, ctype functions and macros and some functions of the
588 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
589 be extensively tested in the future. Standard disclaimer here.
590 Library is not automatically build yet. But one can build it by
591 invoking 'make' inside the libc directory.
592 * added ADC library under libio. Preliminary version yet.

602 * (pic16_storeForReturn): optimized return of 0,
603 * (genCmp): experimental code for new genCmp which uses PIC18's
604 special compare&skip instructions. Initial tests fail some times
605 with variables grater than 1 byte in size, so new code is disabled,
606 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
608 * (genCast): began a fix to optimize the casting of a bit to another
609 bit, now assigning a bitfield to another bitfield will fail, sorry,

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

620 caused stop processing pCodes after a inline assembly block,
621 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3582 * src/pic/pcoderegs.c,
3584 * src/pic/ralloc.h: applied patch from Slade Rich;
3585 added support for multiple code pages and multiple RAM banks on the
3586 PIC 14 port. The ASM files now no longer simply assume all the
3587 code / RAM are in the same page / bank. This means the linker can
3588 safely allocate code/RAM of separate ASM files to different pages/banks.
3589 * doc/sdccman.lyx: added Slade's tips
3590 * src/mcs51/peeph.def: fixed bug #880768

3599 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3602 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3603 strtof is not part of C89 and isn't included with Mac OS X.
3605 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3607 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
3608 shiftL2Left2Result): fixed bug #879326
3609 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

3632 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3634 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3635 loaded with the linker search paths (-L arguments) and the libraries
3636 to be linked with the current source (-l arguments). Changes
3637 currently will affect only the pic16 port.
3638 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3639 include path the port specific paths and port specific libraries,
3640 * gplink command now contains the $3 argument,
3641 * src/pic16/device.h,
3642 * src/pic16/device.c,: structure PIC_device is made public and
3643 renamed to PIC16_device, the same for variable Pics which is renamed
3644 to Pics16. Updated all references to them.
3645 * src/pic16/glue.c (pic16glue): corrected bug with code
3646 initialization which bypassed the variable initializations block.
3648 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3649 COMPILE_FLAGS and added the --nostdinc option
3651 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3656 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3658 Documenting changes from previous commits.
3659 * configure.in (version 1.56),
3660 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3661 when generating output files to configure the pic16 library,
3662 but now I've commented it out, since gputils aren't installed in the
3663 SF compile farm, so library won't compile
3665 * device/lib/Makefile.in (version 1.56): initially I've added in
3666 target 'all' the prerequestive 'model-pic16' so it compiled the
3667 pic16 library, but now I've commented it out for the same reasons
3669 * added targets 'model-pic16' and 'objects-pic16' to compile the
3671 * added target 'port-specific-objects-pic16' to handle the
3672 generated libraries and copy them into the build/ directory
3673 * added target 'clean-intermediate-pic16' to clean intermediate
3674 files into pic16 directory
3675 * in target 'installdirs' added line to create directory pic16 in
3676 the installation path
3678 * device/include/Makefile.in (version 1.11): in target 'install'
3679 added lines to copy all header files to installation path,
3680 * in target 'installdirs' added line create directory for pic16
3681 headers in the installation path

3696 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3697 option so that it actually works. Made it specific to the z80, since
3698 the gbz80 doesn't have these kinds of I/O ports.
3700 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3702 * device/include/z180.h,

3724 Mainly changes to support compilation of the device libraries
3725 * src/pic16/device.c: stack is allocated via symbol and not
3726 via literal number. The symbol is placed in the corresponding
3727 position of the data ram
3728 * (pic16_dump_section): relocatable and absolute uninitialized
3729 data are now emitted in sorted order to reduce section naming,
3730 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3731 weren't marked as being in the access bank,
3733 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3735 Added portion of GNU PIC Library under the directory
3736 device/include/pic16 and device/lib/pic16. These files
3737 contain the declarations of SFRs for the PIC18Fxx2 devices.
3738 The directory is initialized via configure from toplevel.
3740 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3742 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3768 all over. Telling LaTeX to be less strict with word spacing
3769 to better keep the right margin. Changed some notes about
3770 maintainance of the ports in section 3.2.1 - is it OK like this?
3772 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3810 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3812 * src/pic16/peeph.def: all peepholes with movff are commented out,
3813 because there is a problem in the pcode peep optimizer,
3814 * src/pic16/ralloc.c: the register allocator can now reuse local

3934 * support/valdiag/Makefile,
3935 * support/valdiag/valdiag.py,
3936 * support/valdiag/tests/*

3966 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3968 PIC16 port related changes:
3969 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3970 added variable stackPos,
3972 * gen.c: genCall, assignResultValue: added support for
3973 pushing/retrieving function parameters to/from stack,
3974 genFunction,genEndFunction: setup stack frame for the
3976 genAddrOf: will be changed according to bug 863624
3978 * added files genutils.c and genutils.h which contain gen*
3979 debugged and optimised functions extracted from gen.c
3981 * glue.c: added variable 'externs' which holds extern symbols,
3982 pic16emitRegularMap: is modified to properly handle relocatable
3983 symbols under the new scheme,
3984 pic16createInterruptVect: is modified
3985 pic16printPublics: is modified to emit 'global' assembler directives,
3986 added pic16_printExterns to print extern symbols,
3987 pic16glue: initializes stack/frame pointer in the beginning of
3988 the assembly output. Temporary hack, will be corrected later,
3989 because gplink yet does not support stack and SDCC does not
3990 yet support a type of crt0.o object to create the final binary.
3992 * Removed many lines that contain 8051 legacy code.
3993 * The code is finally placed under a 'code' directive.
3994 * Added port specific options.
3996 * _process_pragma: simplified since now we do not need *special*
3997 include file to define SFR registers. But a separate header
3998 will be needed. This will be developed later.
3999 * _pic16_parseOptions: added, parses port specific options:
4000 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4001 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4002 --preplace-udata-with=
4004 * _pic16_setDefaultOptions: modified to initialize section names,
4005 but hack is temporarly out of order since it needs improvement.
4006 * _pic16_genAssemblerPreamble: configuration words are emitted by
4007 their address instead of their name. This part is incomplete and
4008 supports only the 18Fxx2 devices. Other devices will emit an error
4009 during assembly since they do not contain the same set of config
4011 * _pic16_genIVT: is modified,
4013 * pcode.c: added definitions for some hardware registers that are needed
4015 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4016 All PCI entries are updated. Now LFSR is supported.
4017 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4018 * added pic16_newpCodeOpLit2 to support instructions with
4019 two literal arguments
4020 * pic16_pCode2str: corrected code that emits assembler instructions
4021 with two literal operands and those that have an access bit modifier
4022 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4023 this fixes a bug which caused some labels to be lost, when an
4024 assembler directive was added, i.e. banksel,
4025 * pic16_FixRegisterBanking: improved logic that causes the insertion
4027 * InlineFunction: functions that are called once, are not any more
4028 inlined. This can be a port option in the future,
4030 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4032 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4033 hold the corresponding uninitialized symbols,
4034 * pic16_allocProcessorRegister: registers have explicit marked the
4036 * pic16_allocInternalRegister: registers are explicit marked as
4038 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4039 processing list, so bit registers were lost,
4042 * ralloc.h: added field 'accessBank' and original symbol operand
4043 in register definition,
4044 * removed the field isMapped from register definition,
4046 ** Several functions have been removed from various sources:
4047 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4048 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4049 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4050 pic16_assignRelocatableRegisters
4052 ** others have been introduced:
4053 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4054 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4056 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4058 * support/scripts/inc2h.pl: changed definition of BIT_AT
4059 to emit 'sbit at' instead of 'bit at'. This was a request.
4061 PIC16 port related preliminary changes:
4062 * gen.c: prefixed function popRegFromString with
4063 pic16_ and all references to it corrected
4064 * pcode.c: all pic16_pc_* hardware registers prefixed
4065 with underscore (_),
4066 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4067 * ralloc.c: newReg(): when register is REG_SFR then
4068 set address to rIdx,
4069 pic16_allocProcessorRegister(): marks register wasUsed=0
4070 pic16_writeUsedRegs(): added a call to assign processor
4071 registers via pic16_assignFixedRegisters
4073 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4075 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4076 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4077 variables in unused register banks. Also the SSEG is placed
4078 wherever there is enough space for it, and IDATA can be anywhere
4079 in internal RAM. For now compile using -Wl-Y[stack_size].
4080 The mem file is different for this option as well, since it
4081 makes no sense of talking about DSEG lenght.
4083 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4085 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5076 and JUMPTABLE iCodes properly now (worked by accident before)
5077 * src/mcs51/gen.c (leftRightUseAcc),
5078 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5079 iCode properly now. Use getSize instead of nRegs since a & b
5080 aren't part of the nRegs tally.
5082 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5084 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5088 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5090 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5091 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5092 fetching of the pointer
5093 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5094 copied from genNearPointerSet()
5095 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5096 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5097 If they pop r0/r1 they must be called in the opposite order than aopOp().
5098 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5099 (resp. --stack-auto), prepared for --xstack

5110 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5112 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5113 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5114 type for bits was changed. It resulted in bit variables becoming
5115 global, which is not permitted in PIC 14 assembly output.
5117 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5119 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5132 A few small changes that speed up the peephole optimizer.
5136 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5138 Try to make the peephole optimizer smarter by maintaining
5139 an association between the assembly source code and the
5140 iCodes that originated them. Put this information to use
5141 with a new peephole rule condition "notVolatile" so that
5142 the rules can be aggressive yet still safe.
5147 * src/mcs51/peeph.def
5149 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5153 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5154 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5155 if the left or right operand symbols have the accuse flag set.
5157 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5159 Changed the type of the result of the ! (NOT) operator to char;
5160 previously it returned the same type as the source. This allows
5161 us to eliminate all the genFloatNot functions (all of its target
5162 implementations were very buggy) since !float can use the same
5165 * src/SDCCicode.c (ast2iCode): ! returns char

5167 * src/ds390/gen.c (genNot, genNotFloat),
5168 * src/z80/gen.c (genNot, genNotFloat),
5169 * src/pic/gen.c (genNot, genNotFloat),
5170 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

5174 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5175 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5176 during interrupts. Ensure WSAVE is located at a shared bank address.
5177 2. Fixed page selection in some places
5178 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5179 the registers name strings.
5180 4. Fixed "signed / unsigned compare" compiler warnings.
5181 5. The PIC port manages its own allocation of the general purpose
5182 registers, but makes no attempt to reuse them. As a result when
5183 compiling it soon runs out of general purpose registers. Some
5184 additional code was added to the files pcode.c and device.c to walk
5185 through the function call tree and rename the registers so that they
5195 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5196 genPlus() & genMinus() when the result is the same as left or right

5202 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5204 Made bitfield a distinct type from bit so that bitfields
5205 convert as per ANSI C and bits retain their traditional
5206 boolean style behaviour. Implemented bitfield support in
5214 * src/ds390/gen.c: bit v bitfield split
5215 * src/z80/gen.c: New support for bitfields
5216 * support/regression/tests/bitfields.c: reenabled z80,
5219 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5221 Rules 246.x, 247.x relate to bitfields, the others speed up
5222 access to xdata mapped I/O devices.
5224 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5226 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5228 Cleaned up genPackBits and genUnpackBits and added two helper
5229 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5230 for literal assignments in genPackBits (thanks to Frieder for
5236 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5238 Fixed bug #748310 (pointer to function type mishandled when the
5239 function name is omitted). Also fixed a SIGSEGV when a function
5240 attribute (reentrant, etc) is used on a non-function or on a
5241 function but misplaced before the parameter list.
5243 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5245 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5246 * support/Util/SDCCerr.h,

5268 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5270 Made the constant following the "interrupt" keyword optional. If
5271 omitted, the function will not automatically be given an entry
5272 in the interrupt vector table (similar to #pragma NOIV, but
5273 less syntacticly kludgy). The interrupt number is also now
5274 range checked. Also fixed a bug in the high order bit example

5290 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5292 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5293 be re-activated by defining REDUCE_LITERALS)
5294 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5295 unsigned, but are signed by default
5296 * src/SDCCval.c (constVal): rearranged
5297 * src/SDCCval.c (valMod): preliminary fix
5298 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5750 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5751 the regression tests I'm not brave enough to enable 245.b, 245.c
5752 * doc/sdccman.lyx: added latex preamble for hyperref package.
5753 Using pdflatex this will give you a hyperlinked pdf file with
5754 bookmarks. (prepend '%' before /usepackage if this breaks something)

5768 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
5770 Applied patch from bug 737905 (renamed yylineo to mylineno):
5777 * src/pic16/pcode.c: Cleaned warnings
5778 * src/pic16/pcodeflow.c: Cleaned warnings
5779 * src/pic16/pcoderegs.c: Cleaned warnings

5792 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5794 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5795 it can be defined with CFLAGS when running configure
5796 * src/SDCCmain.c: fixed compiling + linking with object files
5798 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5800 * configure.in: configure for pic16 port,
5801 added --disable-pic16-port
5802 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5803 * src/SDCCmain.c: linkOptions is changed to set *,
5804 added if/endif conditional macros to remove options help
5805 messages from optionsTable when a port is not configured, added
5806 support for the PIc16 port in the ports table, when executing
5807 the compiler with no port specified on command line, a default
5808 port is selected with the new macro DEFAULT_PORT which is
5809 defined in port.h, in setDefaultOptions() linkOptions is removed
5810 from initialization assignment, since now it is a set,
5811 parseCmdLine uses setParseWithComma for linkOptions, in
5812 linkEdit() linkOptions are accessed with new function indexSet()
5813 which returns the i'th item of a set variable. See SDCCset.c, in
5814 linkEdit() when calling buildCmdLine(), added linkOptions as
5815 last argument. Now users can pass arguments to gplink via the
5816 -Wl option, main() uses pic16glue() to glue up pic16 programs
5817 * src/SDCCpeeph.c: various changes to support pic16
5818 * src/SDCCset.c: added function void *indexSet(set *, int) to
5819 return the i'th item of the set

5824 added macro DEFAULT_PORT
5825 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
5826 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5828 * src/pic16/glue.c: commented out some error producing lines
5829 * src/pic16/main.c: __config directives are commented out to stop
5830 gpasm complaining and test the linkage with gplink, _linkCmd and
5831 _asmCmd changed to be more gplink and gpasm friendly
5832 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5833 produced an error when parsed, peep rule 12 is added to utilize
5834 movff, but it is commented out since the pCode does not support
5835 yet a command with 2 address arguments
5837 2003-05-18 <johan AT balder>
5839 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5840 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5864 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5866 2003-05-11 Borut Razem <borut.razem AT siol.net>
5868 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5869 the path of bin directory, so that PATH is the only env. variable, which has to be set
5870 in case of standard installation.
5871 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6903 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6904 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6905 following files to include the previous two files: aslink.dsp,
6906 Makefile.aslink, Makefile.bcc, and Makefile.in.
6908 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6909 .adb instead of .cdb
6911 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6913 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6914 value from option --iram-size.
6916 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6918 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6921 2002-09-18 <wiml AT hhhh.org>
6923 * SDCClrange.h: exposed setFromRange() and setToRange()
6924 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6925 packRegsForAccUse() (bug 542397)
6926 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6927 multiple times and emitting the fetch operations more than once
6928 added aopGetUsesAcc() function to allow binary operators to
6929 fetch their operands in the correct order; made genMinus() emit
6930 compact code for X = LITERAL - Y
6932 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6933 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6934 sprintf() in line 1267.
6936 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6940 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6941 Changes to aslink (All the changes are marked with 'JCF'):
6943 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6946 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6947 area BSEG. Also moves, if possible, the DATA area down into the internal
6948 ram so more space is available.
6950 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6953 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6954 not bytes. Function summary() which creates a memory usage summary
6955 file with extension .mem. Reports of overlaping stack and small stack
6956 size. If the space for the stack is less than 16 bytes aslink trows a
6959 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6960 the 8051. Option 'y' for memory summary output file.
6962 Changes to sdcc (All the changes are marked with 'JCF'):
6964 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6966 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6967 overlaying area for it (uses RegBankUsed[4]).
6969 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6970 bank zero as used by default. By default aslink locates the stack
6971 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6972 the creation of the .mem file. Delegates the allocation of data area
6973 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6974 the begining of the stack area to aslink.
6976 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6977 glue() in SDCCglue.c creates an area for it.
6979 2002-09-03 Borut Razem <borut.razem AT siol.net>
6980 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,

6983 errors, assertions, ...
6985 2002-08-29 Borut Razem <borut.razem AT siol.net>
6986 * sdcc/support/cpp2/auto-host_vc_in.h:
6987 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6988 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6989 Maybe there is a similar problem with BORLANDC? It should be checked!
6991 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6992 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6993 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6994 was not executed, and the compiler (cl) launched a warning:
6995 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6997 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

7005 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7006 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7007 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7008 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7009 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7010 - added Release configuration in VS projects
7011 - review of compiler an linker options
7012 - VC .exe files are generated in bin_vc directory, not to interfere
7013 with binaries generated from other projects (cygwin, mingw, bcc ...)
7015 * sdcc/src/yacc.dsp: added
7017 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7018 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7019 and insert the version number definitions from .version
7021 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7023 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7033 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7035 2002-08-10 Borut Razem <borut.razem AT siol.net>
7036 * src/SDCCmain.c (main):
7037 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7038 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7039 The consequence was that some temporary files were not removed.
7042 unification of code in functions tempfilename() and tempfile():
7043 function tempnam() is defined in Visual Studio 6.0 and .NET
7045 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7047 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7048 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7049 - removed compiler command line option /WX: Treats all warnings as errors
7050 - update a list of source files, included into the project
7052 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7053 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7054 changed project type to Generic Project so that can be correcly converted to VS.NET project
7056 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7058 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7060 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7062 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7063 added return 0 statements after assert() to make compiler happy
7065 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7066 added newline in the def file to keep MSC compiler satisfied
7068 * sdcc/src/z80/gen.c:
7069 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7070 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7071 - solved MSC error in function aopDump()
7073 * sdcc_vc.h: define PREFIX as "\\sdcc"
7075 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7076 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7130 Compiler generated registers for interrupt context saving
7131 were not getting allocated.
7133 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7136 Fixed left shift. Will promote the left side of a left shift
7137 if a) left shifting more than size of operand or b) when assigned
7138 to something size > size of left side
7140 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7248 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7250 * sdcc/src/SDCCloop.c:
7251 Previous fix was not good. basic blocks that have "break" or "return" are
7252 not really partof a loop , but live ranges used in these blocks should
7253 be live thru the entire loop, so set partOfLoop but don't add them to
7256 2002-02-21 <johan AT FRIJA>
7258 * src/SDCCcse.c: fixed bug #514308
7260 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7266 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7268 2002-02-10 Karl Bongers <karl AT turbobit.com>
7271 Fixed up SDCDB debugger somewhat. Updated debugger/README
7272 with lots of comments and notes.
7274 * device/examples/test2.c:
7275 Fix bug, "red" variable not being initialized(compiler complained).

7281 * sim/ucsim/cmd.src/cmdset.cc:
7282 Took out debug printfs in ucsim "next" command.
7285 Karl and Johan start ucsim XA support. Most dissassembly working,
7286 about 75% emulation done(plenty of work remaining).
7288 * sim/ucsim/z80.src:
7289 Add Z80 support to ucsim, add test-ucz80 regression test,
7290 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
