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

409 * (malloc.h): added CVS Id tag,
410 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
412 * added libc directory. The current version of LibC contains string
413 functions, ctype functions and macros and some functions of the
414 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
415 be extensively tested in the future. Standard disclaimer here.
416 Library is not automatically build yet. But one can build it by
417 invoking 'make' inside the libc directory.
418 * added ADC library under libio. Preliminary version yet.

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

443 * (isBankInstruction): modified to return 0 for no banking instruction,
444 and 1 for banking instruction,
445 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
446 caused stop processing pCodes after a inline assembly block,
447 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3461 loaded with the linker search paths (-L arguments) and the libraries
3462 to be linked with the current source (-l arguments). Changes
3463 currently will affect only the pic16 port.
3464 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3465 include path the port specific paths and port specific libraries,
3466 * gplink command now contains the $3 argument,
3467 * src/pic16/device.h,
3468 * src/pic16/device.c,: structure PIC_device is made public and

3484 Documenting changes from previous commits.
3485 * configure.in (version 1.56),
3486 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3487 when generating output files to configure the pic16 library,
3488 but now I've commented it out, since gputils aren't installed in the
3489 SF compile farm, so library won't compile
3491 * device/lib/Makefile.in (version 1.56): initially I've added in
3492 target 'all' the prerequestive 'model-pic16' so it compiled the
3493 pic16 library, but now I've commented it out for the same reasons
3495 * added targets 'model-pic16' and 'objects-pic16' to compile the
3497 * added target 'port-specific-objects-pic16' to handle the
3498 generated libraries and copy them into the build/ directory
3499 * added target 'clean-intermediate-pic16' to clean intermediate
3500 files into pic16 directory
3501 * in target 'installdirs' added line to create directory pic16 in
3502 the installation path

3505 added lines to copy all header files to installation path,
3506 * in target 'installdirs' added line create directory for pic16
3507 headers in the installation path

3523 option so that it actually works. Made it specific to the z80, since
3524 the gbz80 doesn't have these kinds of I/O ports.
3526 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3528 * device/include/z180.h,

3561 Added portion of GNU PIC Library under the directory
3562 device/include/pic16 and device/lib/pic16. These files
3563 contain the declarations of SFRs for the PIC18Fxx2 devices.
3564 The directory is initialized via configure from toplevel.

3593 * doc/sdccman.lyx: Moved and added some sections, small changes
3594 all over. Telling LaTeX to be less strict with word spacing
3595 to better keep the right margin. Changed some notes about
3596 maintainance of the ports in section 3.2.1 - is it OK like this?
3598 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3600 SDCC source changes:
3601 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3607 processor registers declared internally by the port are emitted in
3608 the translation as equates,
3609 * src/pic16/gen.c: inline code is passed unprocessed to the

3635 UPPER for immediate operands,
3636 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3638 * src/pic16/peeph.def: all peepholes with movff are commented out,
3639 because there is a problem in the pcode peep optimizer,
3640 * src/pic16/ralloc.c: the register allocator can now reuse local

3733 include information about variables allocated to the overlay
3736 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3738 * as/mcs51/lkmain.c: Help about -Y option

3750 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3752 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3753 (default behaviour).
3755 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3757 A python script to validate compiler diagnostic messages. It can be
3758 used to verify that sdcc complains about bad c source code and
3759 gives a good location of the error.
3760 * support/valdiag/Makefile,
3761 * support/valdiag/valdiag.py,
3762 * support/valdiag/tests/*
3764 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3777 * src/common.h: added ifndef/define/endif macros
3778 around the header file.
3779 Bug reported from Jesus Calvino-Fraga
3781 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3783 * sdcc.spec: updated
3784 * device/include/Makefile.in: don't install CVS directories
3785 * device/lib/Makefile.in: added removal of CVS directories after install
3786 * doc/Makefile: fixed install, added local_icons
3787 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3788 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3789 * src/ds390/gen.c (genRightShift): fixed bug #870788
3790 * src/SDCCast.c (decorateType): fixed bug #870781
3792 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3794 PIC16 port related changes:
3795 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3796 added variable stackPos,
3798 * gen.c: genCall, assignResultValue: added support for
3799 pushing/retrieving function parameters to/from stack,
3800 genFunction,genEndFunction: setup stack frame for the
3802 genAddrOf: will be changed according to bug 863624
3804 * added files genutils.c and genutils.h which contain gen*
3805 debugged and optimised functions extracted from gen.c
3807 * glue.c: added variable 'externs' which holds extern symbols,
3808 pic16emitRegularMap: is modified to properly handle relocatable
3809 symbols under the new scheme,
3810 pic16createInterruptVect: is modified
3811 pic16printPublics: is modified to emit 'global' assembler directives,
3812 added pic16_printExterns to print extern symbols,
3813 pic16glue: initializes stack/frame pointer in the beginning of
3814 the assembly output. Temporary hack, will be corrected later,
3815 because gplink yet does not support stack and SDCC does not
3816 yet support a type of crt0.o object to create the final binary.
3818 * Removed many lines that contain 8051 legacy code.
3819 * The code is finally placed under a 'code' directive.
3820 * Added port specific options.
3822 * _process_pragma: simplified since now we do not need *special*
3823 include file to define SFR registers. But a separate header
3824 will be needed. This will be developed later.
3825 * _pic16_parseOptions: added, parses port specific options:
3826 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3827 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3828 --preplace-udata-with=
3830 * _pic16_setDefaultOptions: modified to initialize section names,
3831 but hack is temporarly out of order since it needs improvement.
3832 * _pic16_genAssemblerPreamble: configuration words are emitted by
3833 their address instead of their name. This part is incomplete and
3834 supports only the 18Fxx2 devices. Other devices will emit an error
3835 during assembly since they do not contain the same set of config
3837 * _pic16_genIVT: is modified,
3839 * pcode.c: added definitions for some hardware registers that are needed
3841 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3842 All PCI entries are updated. Now LFSR is supported.
3843 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3844 * added pic16_newpCodeOpLit2 to support instructions with
3845 two literal arguments
3846 * pic16_pCode2str: corrected code that emits assembler instructions
3847 with two literal operands and those that have an access bit modifier
3848 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3849 this fixes a bug which caused some labels to be lost, when an
3850 assembler directive was added, i.e. banksel,
3851 * pic16_FixRegisterBanking: improved logic that causes the insertion
3853 * InlineFunction: functions that are called once, are not any more
3854 inlined. This can be a port option in the future,
3856 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3858 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3859 hold the corresponding uninitialized symbols,
3860 * pic16_allocProcessorRegister: registers have explicit marked the
3862 * pic16_allocInternalRegister: registers are explicit marked as
3864 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3865 processing list, so bit registers were lost,
3868 * ralloc.h: added field 'accessBank' and original symbol operand
3869 in register definition,
3870 * removed the field isMapped from register definition,
3872 ** Several functions have been removed from various sources:
3873 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3874 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3875 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3876 pic16_assignRelocatableRegisters
3878 ** others have been introduced:
3879 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3880 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3882 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3884 * support/scripts/inc2h.pl: changed definition of BIT_AT
3885 to emit 'sbit at' instead of 'bit at'. This was a request.
3887 PIC16 port related preliminary changes:
3888 * gen.c: prefixed function popRegFromString with
3889 pic16_ and all references to it corrected
3890 * pcode.c: all pic16_pc_* hardware registers prefixed
3891 with underscore (_),
3892 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3893 * ralloc.c: newReg(): when register is REG_SFR then
3894 set address to rIdx,
3895 pic16_allocProcessorRegister(): marks register wasUsed=0
3896 pic16_writeUsedRegs(): added a call to assign processor
3897 registers via pic16_assignFixedRegisters
3899 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3901 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3902 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3903 variables in unused register banks. Also the SSEG is placed
3904 wherever there is enough space for it, and IDATA can be anywhere
3905 in internal RAM. For now compile using -Wl-Y[stack_size].
3906 The mem file is different for this option as well, since it
3907 makes no sense of talking about DSEG lenght.
3909 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3911 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3912 in certain cases, e.g. when ROM assignment, patch provided
3913 from Albert den Haan.
3915 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4058 * src/mcs51/peephole.def,
4059 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4060 (allows non-interrupt and interrupt code to safely compete for a resource

4800 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4801 support for standard C idiom of memory mapped variables; for
4802 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4803 to xdata int at 0x1234 tempvar = 1.
4804 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4805 provided by Akiya ISHIDA

4821 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4823 Fixed bug #621531 (const & volatile confusion in the type chain).
4824 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4825 refer to the const or volatile state of the pointer itself.

4890 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
4891 pcoderegs.h, ralloc.c, ralloc.h
4892 * main.c: added top header and GPL license notice

4903 * src/mcs51/gen.c (leftRightUseAcc),
4904 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4905 iCode properly now. Use getSize instead of nRegs since a & b
4906 aren't part of the nRegs tally.
4908 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4910 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
4911 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
4912 before instructions that use the _STATUS register
4914 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
4916 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4917 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4918 fetching of the pointer
4919 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4920 copied from genNearPointerSet()
4921 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4922 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4923 If they pop r0/r1 they must be called in the opposite order than aopOp().
4924 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4925 (resp. --stack-auto), prepared for --xstack

4934 these ports have their own __sdcc_external_start()
4936 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4938 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4939 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4940 type for bits was changed. It resulted in bit variables becoming
4941 global, which is not permitted in PIC 14 assembly output.
4943 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4945 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4956 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4958 A few small changes that speed up the peephole optimizer.
4962 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4964 Try to make the peephole optimizer smarter by maintaining
4965 an association between the assembly source code and the
4966 iCodes that originated them. Put this information to use
4967 with a new peephole rule condition "notVolatile" so that
4968 the rules can be aggressive yet still safe.
4973 * src/mcs51/peeph.def
4975 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4979 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4980 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4981 if the left or right operand symbols have the accuse flag set.
4983 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4985 Changed the type of the result of the ! (NOT) operator to char;
4986 previously it returned the same type as the source. This allows
4987 us to eliminate all the genFloatNot functions (all of its target
4988 implementations were very buggy) since !float can use the same
4991 * src/SDCCicode.c (ast2iCode): ! returns char
4992 * src/mcs51/gen.c (genNot, genNotFloat),
4993 * src/ds390/gen.c (genNot, genNotFloat),
4994 * src/z80/gen.c (genNot, genNotFloat),
4995 * src/pic/gen.c (genNot, genNotFloat),
4996 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
4998 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5000 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5001 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5002 during interrupts. Ensure WSAVE is located at a shared bank address.
5003 2. Fixed page selection in some places
5004 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5005 the registers name strings.
5006 4. Fixed "signed / unsigned compare" compiler warnings.
5007 5. The PIC port manages its own allocation of the general purpose
5008 registers, but makes no attempt to reuse them. As a result when
5009 compiling it soon runs out of general purpose registers. Some
5010 additional code was added to the files pcode.c and device.c to walk
5011 through the function call tree and rename the registers so that they
5021 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5022 genPlus() & genMinus() when the result is the same as left or right
5024 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5028 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5030 Made bitfield a distinct type from bit so that bitfields
5031 convert as per ANSI C and bits retain their traditional
5032 boolean style behaviour. Implemented bitfield support in
5040 * src/ds390/gen.c: bit v bitfield split
5041 * src/z80/gen.c: New support for bitfields
5042 * support/regression/tests/bitfields.c: reenabled z80,
5045 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5047 Rules 246.x, 247.x relate to bitfields, the others speed up
5048 access to xdata mapped I/O devices.
5050 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5052 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5054 Cleaned up genPackBits and genUnpackBits and added two helper
5055 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5056 for literal assignments in genPackBits (thanks to Frieder for
5062 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5064 Fixed bug #748310 (pointer to function type mishandled when the
5065 function name is omitted). Also fixed a SIGSEGV when a function
5066 attribute (reentrant, etc) is used on a non-function or on a
5067 function but misplaced before the parameter list.
5069 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5071 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5072 * support/Util/SDCCerr.h,
5073 * support/Util/SDCCerr.c: Added func attr misuse error msg
5075 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5077 Fixed bug #787649 by anonymous
5078 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5079 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5081 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5092 * support/regression/tests/bitfields.c: tests added
5094 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5096 Made the constant following the "interrupt" keyword optional. If
5097 omitted, the function will not automatically be given an entry
5098 in the interrupt vector table (similar to #pragma NOIV, but
5099 less syntacticly kludgy). The interrupt number is also now

5627 added --disable-pic16-port
5628 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5629 * src/SDCCmain.c: linkOptions is changed to set *,
5630 added if/endif conditional macros to remove options help
5631 messages from optionsTable when a port is not configured, added
5632 support for the PIc16 port in the ports table, when executing
5633 the compiler with no port specified on command line, a default
5634 port is selected with the new macro DEFAULT_PORT which is
5635 defined in port.h, in setDefaultOptions() linkOptions is removed
5636 from initialization assignment, since now it is a set,
5637 parseCmdLine uses setParseWithComma for linkOptions, in
5638 linkEdit() linkOptions are accessed with new function indexSet()
5639 which returns the i'th item of a set variable. See SDCCset.c, in
5640 linkEdit() when calling buildCmdLine(), added linkOptions as
5641 last argument. Now users can pass arguments to gplink via the
5642 -Wl option, main() uses pic16glue() to glue up pic16 programs
5643 * src/SDCCpeeph.c: various changes to support pic16

5654 * src/pic16/glue.c: commented out some error producing lines
5655 * src/pic16/main.c: __config directives are commented out to stop
5656 gpasm complaining and test the linkage with gplink, _linkCmd and
5657 _asmCmd changed to be more gplink and gpasm friendly
5658 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5659 produced an error when parsed, peep rule 12 is added to utilize
5660 movff, but it is commented out since the pCode does not support

6706 2003-01-04 <johan AT balder>
6708 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6710 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6711 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6713 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

6720 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6721 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6723 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6724 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6726 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6728 * in \sdcc\as\mcs51\ changed these files in order to create an
6729 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6730 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6731 following files to include the previous two files: aslink.dsp,
6732 Makefile.aslink, Makefile.bcc, and Makefile.in.
6734 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6735 .adb instead of .cdb
6737 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6739 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6740 value from option --iram-size.
6742 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6744 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6747 2002-09-18 <wiml AT hhhh.org>
6749 * SDCClrange.h: exposed setFromRange() and setToRange()
6750 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6751 packRegsForAccUse() (bug 542397)
6752 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6753 multiple times and emitting the fetch operations more than once
6754 added aopGetUsesAcc() function to allow binary operators to
6755 fetch their operands in the correct order; made genMinus() emit
6756 compact code for X = LITERAL - Y
6758 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6759 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6760 sprintf() in line 1267.
6762 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6763 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6766 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6767 Changes to aslink (All the changes are marked with 'JCF'):
6769 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6772 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6773 area BSEG. Also moves, if possible, the DATA area down into the internal
6774 ram so more space is available.
6776 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6779 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6780 not bytes. Function summary() which creates a memory usage summary
6781 file with extension .mem. Reports of overlaping stack and small stack
6782 size. If the space for the stack is less than 16 bytes aslink trows a
6785 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6786 the 8051. Option 'y' for memory summary output file.
6788 Changes to sdcc (All the changes are marked with 'JCF'):
6790 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6792 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6793 overlaying area for it (uses RegBankUsed[4]).
6795 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6796 bank zero as used by default. By default aslink locates the stack
6797 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6798 the creation of the .mem file. Delegates the allocation of data area
6799 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6800 the begining of the stack area to aslink.
6802 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6803 glue() in SDCCglue.c creates an area for it.
6805 2002-09-03 Borut Razem <borut.razem AT siol.net>
6806 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6807 sdcc/src/pic/glue.c:
6808 introduced atexit() handler for teporay files removal in case of
6809 errors, assertions, ...
6811 2002-08-29 Borut Razem <borut.razem AT siol.net>
6812 * sdcc/support/cpp2/auto-host_vc_in.h:
6813 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6814 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6815 Maybe there is a similar problem with BORLANDC? It should be checked!
6817 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6818 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6819 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6820 was not executed, and the compiler (cl) launched a warning:
6821 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6823 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6824 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6826 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6827 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6829 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6830 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6831 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6832 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6833 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6834 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6835 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6836 - added Release configuration in VS projects
6837 - review of compiler an linker options
6838 - VC .exe files are generated in bin_vc directory, not to interfere
6839 with binaries generated from other projects (cygwin, mingw, bcc ...)
6841 * sdcc/src/yacc.dsp: added
6843 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6844 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6845 and insert the version number definitions from .version
6847 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6849 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6850 added - genarate auto-host.h using auto-host_vc_in.h as template
6853 removed from CVS, generated automatically
6855 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6856 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6858 2002-08-11 Borut Razem <borut.razem AT siol.net>
6859 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6861 2002-08-10 Borut Razem <borut.razem AT siol.net>
6862 * src/SDCCmain.c (main):
6863 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6864 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6865 The consequence was that some temporary files were not removed.
6868 unification of code in functions tempfilename() and tempfile():
6869 function tempnam() is defined in Visual Studio 6.0 and .NET
6871 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6873 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6874 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6875 - removed compiler command line option /WX: Treats all warnings as errors
6876 - update a list of source files, included into the project
6878 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6879 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6880 changed project type to Generic Project so that can be correcly converted to VS.NET project
6882 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6884 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6886 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6888 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6889 added return 0 statements after assert() to make compiler happy
6891 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6892 added newline in the def file to keep MSC compiler satisfied
6894 * sdcc/src/z80/gen.c:
6895 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6896 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6897 - solved MSC error in function aopDump()
6899 * sdcc_vc.h: define PREFIX as "\\sdcc"
6901 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6902 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6905 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6906 - Rewrote the register banking algorithm.
6907 - Added pCode live-range analysis to registers (for now, only non-used and
6908 singly-used registers optimized away)
6910 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6912 * 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.

6937 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6939 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6941 2002-03-28 Johan Knol <johan AT balder>
6943 * src/SDCCval.c: fixed bug #532436
6945 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6947 Added "char *Processor" field to the port structure.
6950 Added -p option. Allows port dependent processor to be specified.
6953 Initialized the new field char *Processor field to NULL in all ports
6956 Compiler generated registers for interrupt context saving
6957 were not getting allocated.
6959 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6962 Fixed left shift. Will promote the left side of a left shift
6963 if a) left shifting more than size of operand or b) when assigned
6964 to something size > size of left side
6966 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6968 tons of changes. Register allocation has been
6969 rewritten. Added customization for the various PICs. Flow
6970 analysis is restructured. ...
6976 Added. device.c is a PIC port hack to accomodate variations
6979 2002-03-13 Michael Hope <michaelh AT vroom>
6981 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6983 2002-03-04 johanknol <johanknol AT manik>
6985 * /src/SDCCval.c: fixed
6987 const unsigned char arr[][2] = { { 0, 1 } };
6988 t18.c:1: error: Initializer element is not constant
6990 2002-03-04 bela <bela AT manik>
6992 * /device/include/mcs51reg.h:
6993 ds89c420 register definition update
6995 2002-03-03 <johan AT FRIJA>
6997 * support/Util/SDCCerr.c: did something, but don't no why anymore
6999 * support/regression/tests/bug-524691.c: made it a little less shy
