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

280 functions, ctype functions and macros and some functions of the
281 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
282 be extensively tested in the future. Standard disclaimer here.

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

3328 loaded with the linker search paths (-L arguments) and the libraries
3329 to be linked with the current source (-l arguments). Changes
3330 currently will affect only the pic16 port.
3331 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3332 include path the port specific paths and port specific libraries,
3333 * gplink command now contains the $3 argument,
3334 * src/pic16/device.h,

3351 Documenting changes from previous commits.
3352 * configure.in (version 1.56),
3353 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3354 when generating output files to configure the pic16 library,
3355 but now I've commented it out, since gputils aren't installed in the
3356 SF compile farm, so library won't compile
3358 * device/lib/Makefile.in (version 1.56): initially I've added in
3359 target 'all' the prerequestive 'model-pic16' so it compiled the
3360 pic16 library, but now I've commented it out for the same reasons
3362 * added targets 'model-pic16' and 'objects-pic16' to compile the
3364 * added target 'port-specific-objects-pic16' to handle the
3365 generated libraries and copy them into the build/ directory
3366 * added target 'clean-intermediate-pic16' to clean intermediate
3367 files into pic16 directory
3368 * in target 'installdirs' added line to create directory pic16 in

3617 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3619 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3620 (default behaviour).
3622 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3624 A python script to validate compiler diagnostic messages. It can be
3625 used to verify that sdcc complains about bad c source code and
3626 gives a good location of the error.
3627 * support/valdiag/Makefile,
3628 * support/valdiag/valdiag.py,
3629 * support/valdiag/tests/*
3631 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3633 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3634 * src/SDCCsymt.c (newEnumType),
3636 * support/Util/SDCCerr.c,
3637 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3639 * support/regression/tests/enum.c: added test for enum values that
3640 require at least 2 bytes of storage.
3642 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3644 * src/common.h: added ifndef/define/endif macros
3645 around the header file.
3646 Bug reported from Jesus Calvino-Fraga
3648 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3650 * sdcc.spec: updated
3651 * device/include/Makefile.in: don't install CVS directories
3652 * device/lib/Makefile.in: added removal of CVS directories after install
3653 * doc/Makefile: fixed install, added local_icons
3654 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3655 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3656 * src/ds390/gen.c (genRightShift): fixed bug #870788
3657 * src/SDCCast.c (decorateType): fixed bug #870781
3659 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3661 PIC16 port related changes:
3662 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3663 added variable stackPos,
3665 * gen.c: genCall, assignResultValue: added support for
3666 pushing/retrieving function parameters to/from stack,
3667 genFunction,genEndFunction: setup stack frame for the
3669 genAddrOf: will be changed according to bug 863624
3671 * added files genutils.c and genutils.h which contain gen*
3672 debugged and optimised functions extracted from gen.c
3674 * glue.c: added variable 'externs' which holds extern symbols,
3675 pic16emitRegularMap: is modified to properly handle relocatable
3676 symbols under the new scheme,
3677 pic16createInterruptVect: is modified
3678 pic16printPublics: is modified to emit 'global' assembler directives,
3679 added pic16_printExterns to print extern symbols,
3680 pic16glue: initializes stack/frame pointer in the beginning of
3681 the assembly output. Temporary hack, will be corrected later,
3682 because gplink yet does not support stack and SDCC does not
3683 yet support a type of crt0.o object to create the final binary.
3685 * Removed many lines that contain 8051 legacy code.
3686 * The code is finally placed under a 'code' directive.
3687 * Added port specific options.
3689 * _process_pragma: simplified since now we do not need *special*
3690 include file to define SFR registers. But a separate header
3691 will be needed. This will be developed later.
3692 * _pic16_parseOptions: added, parses port specific options:
3693 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3694 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3695 --preplace-udata-with=
3697 * _pic16_setDefaultOptions: modified to initialize section names,
3698 but hack is temporarly out of order since it needs improvement.
3699 * _pic16_genAssemblerPreamble: configuration words are emitted by
3700 their address instead of their name. This part is incomplete and
3701 supports only the 18Fxx2 devices. Other devices will emit an error
3702 during assembly since they do not contain the same set of config
3704 * _pic16_genIVT: is modified,
3706 * pcode.c: added definitions for some hardware registers that are needed
3708 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3709 All PCI entries are updated. Now LFSR is supported.
3710 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3711 * added pic16_newpCodeOpLit2 to support instructions with
3712 two literal arguments
3713 * pic16_pCode2str: corrected code that emits assembler instructions
3714 with two literal operands and those that have an access bit modifier
3715 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3716 this fixes a bug which caused some labels to be lost, when an
3717 assembler directive was added, i.e. banksel,
3718 * pic16_FixRegisterBanking: improved logic that causes the insertion
3720 * InlineFunction: functions that are called once, are not any more
3721 inlined. This can be a port option in the future,
3723 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3725 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3726 hold the corresponding uninitialized symbols,
3727 * pic16_allocProcessorRegister: registers have explicit marked the
3729 * pic16_allocInternalRegister: registers are explicit marked as
3731 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3732 processing list, so bit registers were lost,
3735 * ralloc.h: added field 'accessBank' and original symbol operand
3736 in register definition,
3737 * removed the field isMapped from register definition,
3739 ** Several functions have been removed from various sources:
3740 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3741 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3742 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3743 pic16_assignRelocatableRegisters
3745 ** others have been introduced:
3746 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3747 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3749 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3751 * support/scripts/inc2h.pl: changed definition of BIT_AT
3752 to emit 'sbit at' instead of 'bit at'. This was a request.
3754 PIC16 port related preliminary changes:
3755 * gen.c: prefixed function popRegFromString with
3756 pic16_ and all references to it corrected
3757 * pcode.c: all pic16_pc_* hardware registers prefixed
3758 with underscore (_),
3759 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3760 * ralloc.c: newReg(): when register is REG_SFR then
3761 set address to rIdx,
3762 pic16_allocProcessorRegister(): marks register wasUsed=0
3763 pic16_writeUsedRegs(): added a call to assign processor
3764 registers via pic16_assignFixedRegisters
3766 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3768 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3769 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3770 variables in unused register banks. Also the SSEG is placed
3771 wherever there is enough space for it, and IDATA can be anywhere
3772 in internal RAM. For now compile using -Wl-Y[stack_size].
3773 The mem file is different for this option as well, since it
3774 makes no sense of talking about DSEG lenght.
3776 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3778 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3779 in certain cases, e.g. when ROM assignment, patch provided
3780 from Albert den Haan.
3782 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3925 * src/mcs51/peephole.def,
3926 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

3938 multiply defined with mismatching "at" address.
3940 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3942 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

4021 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4023 * src/SDCCast.c (decorateType): disabled a transformation I added in
4024 revision 1.188 (access to fields of a structure at an absolute address);
4025 it breaks with bitfields, extern declarations, and gcse analysis.
4026 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4027 could be assigned through a pointer, so don't complain.
4028 * src/SDCCast.c (astErrors),
4030 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4665 * src/SDCCsymt.c (sclsFromPtr),
4667 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4668 support for standard C idiom of memory mapped variables; for
4669 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4670 to xdata int at 0x1234 tempvar = 1.
4671 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4672 provided by Akiya ISHIDA

4688 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4690 Fixed bug #621531 (const & volatile confusion in the type chain).
4691 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4692 refer to the const or volatile state of the pointer itself.

4783 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4784 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4785 fetching of the pointer
4786 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4787 copied from genNearPointerSet()
4788 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4789 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4790 If they pop r0/r1 they must be called in the opposite order than aopOp().
4791 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4792 (resp. --stack-auto), prepared for --xstack

4803 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4805 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4806 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4807 type for bits was changed. It resulted in bit variables becoming
4808 global, which is not permitted in PIC 14 assembly output.
4810 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4812 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4825 A few small changes that speed up the peephole optimizer.
4829 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4831 Try to make the peephole optimizer smarter by maintaining
4832 an association between the assembly source code and the
4833 iCodes that originated them. Put this information to use
4834 with a new peephole rule condition "notVolatile" so that
4835 the rules can be aggressive yet still safe.
4840 * src/mcs51/peeph.def
4842 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4846 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4847 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4848 if the left or right operand symbols have the accuse flag set.
4850 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4852 Changed the type of the result of the ! (NOT) operator to char;
4853 previously it returned the same type as the source. This allows
4854 us to eliminate all the genFloatNot functions (all of its target
4855 implementations were very buggy) since !float can use the same
4858 * src/SDCCicode.c (ast2iCode): ! returns char

4865 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4867 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4868 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4869 during interrupts. Ensure WSAVE is located at a shared bank address.
4870 2. Fixed page selection in some places
4871 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4872 the registers name strings.
4873 4. Fixed "signed / unsigned compare" compiler warnings.
4874 5. The PIC port manages its own allocation of the general purpose
4875 registers, but makes no attempt to reuse them. As a result when
4876 compiling it soon runs out of general purpose registers. Some
4877 additional code was added to the files pcode.c and device.c to walk
4878 through the function call tree and rename the registers so that they
4888 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4889 genPlus() & genMinus() when the result is the same as left or right
4891 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4895 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4897 Made bitfield a distinct type from bit so that bitfields
4898 convert as per ANSI C and bits retain their traditional
4899 boolean style behaviour. Implemented bitfield support in
4907 * src/ds390/gen.c: bit v bitfield split
4908 * src/z80/gen.c: New support for bitfields
4909 * support/regression/tests/bitfields.c: reenabled z80,
4912 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4914 Rules 246.x, 247.x relate to bitfields, the others speed up
4915 access to xdata mapped I/O devices.
4917 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4919 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4921 Cleaned up genPackBits and genUnpackBits and added two helper
4922 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4923 for literal assignments in genPackBits (thanks to Frieder for
4929 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4931 Fixed bug #748310 (pointer to function type mishandled when the
4932 function name is omitted). Also fixed a SIGSEGV when a function
4933 attribute (reentrant, etc) is used on a non-function or on a
4934 function but misplaced before the parameter list.
4936 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4938 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4939 * support/Util/SDCCerr.h,
4940 * support/Util/SDCCerr.c: Added func attr misuse error msg

4961 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4963 Made the constant following the "interrupt" keyword optional. If
4964 omitted, the function will not automatically be given an entry
4965 in the interrupt vector table (similar to #pragma NOIV, but
4966 less syntacticly kludgy). The interrupt number is also now
4967 range checked. Also fixed a bug in the high order bit example

4981 * src/SDCCicode.c (operandOperation): rewritten some ops
4982 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4983 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4985 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4986 be re-activated by defining REDUCE_LITERALS)
4987 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4988 unsigned, but are signed by default
4989 * src/SDCCval.c (constVal): rearranged
4990 * src/SDCCval.c (valMod): preliminary fix
4991 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5033 constants are unsigned; added recognition of "u" flag for unsigned
5034 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5035 * src/SDCCval.c (valDiv, valMod): fixed signdness
5036 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5037 signedness of modulo, left and right shift

5496 * src/SDCCmain.c: linkOptions is changed to set *,
5497 added if/endif conditional macros to remove options help
5498 messages from optionsTable when a port is not configured, added
5499 support for the PIc16 port in the ports table, when executing
5500 the compiler with no port specified on command line, a default
5501 port is selected with the new macro DEFAULT_PORT which is
5502 defined in port.h, in setDefaultOptions() linkOptions is removed
5503 from initialization assignment, since now it is a set,
5504 parseCmdLine uses setParseWithComma for linkOptions, in
5505 linkEdit() linkOptions are accessed with new function indexSet()
5506 which returns the i'th item of a set variable. See SDCCset.c, in
5507 linkEdit() when calling buildCmdLine(), added linkOptions as
5508 last argument. Now users can pass arguments to gplink via the
5509 -Wl option, main() uses pic16glue() to glue up pic16 programs

5523 gpasm complaining and test the linkage with gplink, _linkCmd and
5524 _asmCmd changed to be more gplink and gpasm friendly
5525 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5526 produced an error when parsed, peep rule 12 is added to utilize
5527 movff, but it is commented out since the pCode does not support
5528 yet a command with 2 address arguments
5530 2003-05-18 <johan AT balder>
5532 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5559 2003-05-11 Borut Razem <borut.razem AT siol.net>
5561 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6548 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6550 2003-01-07 <johan AT balder>
6552 * src/SDCCast.c (decorateType): fixed bug #600035
6554 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6555 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
6556 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
6557 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

6559 * src/pic/ralloc.c: outcommented unused variable to remove warnings
6561 2003-01-06 <karl AT turbobit.com>
6562 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
6565 2003-01-06 <johan AT balder>
6567 * src/SDCCicode.c: fixed array add
6569 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6570 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6571 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6573 2003-01-04 <johan AT balder>
6575 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6577 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6578 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6580 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6581 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6582 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6584 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6585 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6587 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6588 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6590 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6591 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6593 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6595 * in \sdcc\as\mcs51\ changed these files in order to create an
6596 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6597 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6598 following files to include the previous two files: aslink.dsp,
6599 Makefile.aslink, Makefile.bcc, and Makefile.in.
6601 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6602 .adb instead of .cdb
6604 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6606 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6607 value from option --iram-size.
6609 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6611 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6614 2002-09-18 <wiml AT hhhh.org>
6616 * SDCClrange.h: exposed setFromRange() and setToRange()
6617 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6618 packRegsForAccUse() (bug 542397)
6619 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6620 multiple times and emitting the fetch operations more than once
6621 added aopGetUsesAcc() function to allow binary operators to
6622 fetch their operands in the correct order; made genMinus() emit
6623 compact code for X = LITERAL - Y
6625 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6626 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6627 sprintf() in line 1267.
6629 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6630 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6633 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6634 Changes to aslink (All the changes are marked with 'JCF'):
6636 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6639 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6640 area BSEG. Also moves, if possible, the DATA area down into the internal
6641 ram so more space is available.
6643 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6646 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6647 not bytes. Function summary() which creates a memory usage summary
6648 file with extension .mem. Reports of overlaping stack and small stack
6649 size. If the space for the stack is less than 16 bytes aslink trows a
6652 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6653 the 8051. Option 'y' for memory summary output file.
6655 Changes to sdcc (All the changes are marked with 'JCF'):
6657 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6659 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6660 overlaying area for it (uses RegBankUsed[4]).
6662 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6663 bank zero as used by default. By default aslink locates the stack
6664 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6665 the creation of the .mem file. Delegates the allocation of data area
6666 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6667 the begining of the stack area to aslink.
6669 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6670 glue() in SDCCglue.c creates an area for it.
6672 2002-09-03 Borut Razem <borut.razem AT siol.net>
6673 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6674 sdcc/src/pic/glue.c:
6675 introduced atexit() handler for teporay files removal in case of
6676 errors, assertions, ...
6678 2002-08-29 Borut Razem <borut.razem AT siol.net>
6679 * sdcc/support/cpp2/auto-host_vc_in.h:
6680 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6681 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6682 Maybe there is a similar problem with BORLANDC? It should be checked!
6684 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6685 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6686 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6687 was not executed, and the compiler (cl) launched a warning:
6688 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6690 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6691 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6693 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6694 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6696 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6697 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6698 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6699 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6700 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6701 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6702 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6703 - added Release configuration in VS projects
6704 - review of compiler an linker options
6705 - VC .exe files are generated in bin_vc directory, not to interfere
6706 with binaries generated from other projects (cygwin, mingw, bcc ...)
6708 * sdcc/src/yacc.dsp: added
6710 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6711 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6712 and insert the version number definitions from .version
6714 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6716 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6717 added - genarate auto-host.h using auto-host_vc_in.h as template
6720 removed from CVS, generated automatically
6722 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6723 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6725 2002-08-11 Borut Razem <borut.razem AT siol.net>
6726 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6728 2002-08-10 Borut Razem <borut.razem AT siol.net>
6729 * src/SDCCmain.c (main):
6730 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6731 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6732 The consequence was that some temporary files were not removed.
6735 unification of code in functions tempfilename() and tempfile():
6736 function tempnam() is defined in Visual Studio 6.0 and .NET
6738 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6740 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6741 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6742 - removed compiler command line option /WX: Treats all warnings as errors
6743 - update a list of source files, included into the project
6745 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6746 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6747 changed project type to Generic Project so that can be correcly converted to VS.NET project
6749 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6751 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6753 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6755 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6756 added return 0 statements after assert() to make compiler happy
6758 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6759 added newline in the def file to keep MSC compiler satisfied
6761 * sdcc/src/z80/gen.c:
6762 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6763 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6764 - solved MSC error in function aopDump()
6766 * sdcc_vc.h: define PREFIX as "\\sdcc"
6768 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6769 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6772 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6773 - Rewrote the register banking algorithm.
6774 - Added pCode live-range analysis to registers (for now, only non-used and
6775 singly-used registers optimized away)
6777 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6779 * 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.

6806 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6808 2002-03-28 Johan Knol <johan AT balder>
6810 * src/SDCCval.c: fixed bug #532436
6812 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6814 Added "char *Processor" field to the port structure.
6817 Added -p option. Allows port dependent processor to be specified.
6820 Initialized the new field char *Processor field to NULL in all ports
6823 Compiler generated registers for interrupt context saving
6824 were not getting allocated.
6826 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6829 Fixed left shift. Will promote the left side of a left shift
6830 if a) left shifting more than size of operand or b) when assigned
6831 to something size > size of left side
6833 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6835 tons of changes. Register allocation has been
6836 rewritten. Added customization for the various PICs. Flow
6837 analysis is restructured. ...
6843 Added. device.c is a PIC port hack to accomodate variations
6846 2002-03-13 Michael Hope <michaelh AT vroom>
6848 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6850 2002-03-04 johanknol <johanknol AT manik>
6852 * /src/SDCCval.c: fixed
6854 const unsigned char arr[][2] = { { 0, 1 } };
6855 t18.c:1: error: Initializer element is not constant
6857 2002-03-04 bela <bela AT manik>
6859 * /device/include/mcs51reg.h:
6860 ds89c420 register definition update
6862 2002-03-03 <johan AT FRIJA>

6941 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6943 * sdcc/src/SDCCloop.c:
6944 Previous fix was not good. basic blocks that have "break" or "return" are
6945 not really partof a loop , but live ranges used in these blocks should
6946 be live thru the entire loop, so set partOfLoop but don't add them to
6949 2002-02-21 <johan AT FRIJA>
6951 * src/SDCCcse.c: fixed bug #514308
6953 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6956 Fixed BUG #519583. If a conditional block ended in a return/break
6957 statement inside a loop, it was not being considered part of the loop.
6959 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6961 2002-02-10 Karl Bongers <karl AT turbobit.com>
6964 Fixed up SDCDB debugger somewhat. Updated debugger/README
6965 with lots of comments and notes.
6967 * device/examples/test2.c:
6968 Fix bug, "red" variable not being initialized(compiler complained).
6970 * device/examples/Makefile, examples/test3.c:
6971 Add Makefile in device/examples folder, compiles test3.c
6972 for use as a multiple module SDCDB test case.
6974 * sim/ucsim/cmd.src/cmdset.cc:
6975 Took out debug printfs in ucsim "next" command.
6978 Karl and Johan start ucsim XA support. Most dissassembly working,
6979 about 75% emulation done(plenty of work remaining).
6981 * sim/ucsim/z80.src:
6982 Add Z80 support to ucsim, add test-ucz80 regression test,
6983 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6984 Notice z80 compiler fails on examples/test3.c/crc code.
6986 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

6998 3) added __builtin_swapw swap bytes of a short
7000 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7001 1) handle multiple send & receives from register bank1
7002 2) ralloc can now allocate DPTR1 to some liveRanges
7004 * src/SDCCsymt.c, src/SDCCsymt.h:
7005 changes to handle multiple sends & receives
7008 added some pointer arithmetic optimization
7011 added some pointer arithmetic optimizations but not stable yet so not
7012 called from anywhere (will get this working shortly)
7014 * src/SDCCopt.c: fixed for multiple sends & receives
7017 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7018 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7019 set preprocessor defines (depending on options)
7021 * src/SDCCicode.c, src/SDCCicode.h:
7022 changes made to handle multiple sends & receives
7025 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
