314 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
316 * (genCast): began a fix to optimize the casting of a bit to another
317 bit, now assigning a bitfield to another bitfield will fail, sorry,

3343 loaded with the linker search paths (-L arguments) and the libraries
3344 to be linked with the current source (-l arguments). Changes
3345 currently will affect only the pic16 port.
3346 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3347 include path the port specific paths and port specific libraries,
3348 * gplink command now contains the $3 argument,

3366 Documenting changes from previous commits.
3367 * configure.in (version 1.56),
3368 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3369 when generating output files to configure the pic16 library,
3370 but now I've commented it out, since gputils aren't installed in the
3371 SF compile farm, so library won't compile
3373 * device/lib/Makefile.in (version 1.56): initially I've added in
3374 target 'all' the prerequestive 'model-pic16' so it compiled the
3375 pic16 library, but now I've commented it out for the same reasons
3377 * added targets 'model-pic16' and 'objects-pic16' to compile the
3379 * added target 'port-specific-objects-pic16' to handle the
3380 generated libraries and copy them into the build/ directory
3381 * added target 'clean-intermediate-pic16' to clean intermediate
3382 files into pic16 directory
3383 * in target 'installdirs' added line to create directory pic16 in

3613 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3614 how the function variable allocation summary is displayed; also
3615 include information about variables allocated to the overlay
3618 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3620 * as/mcs51/lkmain.c: Help about -Y option
3621 * as/mcs51/lkarea.c: Fixed gcc warnings
3623 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3625 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
3627 * support/valdiag/tests/overflow.c: added
3628 * src/SDCCast.c (decorateType),
3629 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3630 LEFT_OP (left shift)
3632 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3634 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3635 (default behaviour).
3637 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3639 A python script to validate compiler diagnostic messages. It can be
3640 used to verify that sdcc complains about bad c source code and
3641 gives a good location of the error.
3642 * support/valdiag/Makefile,
3643 * support/valdiag/valdiag.py,
3644 * support/valdiag/tests/*
3646 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3648 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3649 * src/SDCCsymt.c (newEnumType),
3651 * support/Util/SDCCerr.c,
3652 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3654 * support/regression/tests/enum.c: added test for enum values that
3655 require at least 2 bytes of storage.
3657 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3659 * src/common.h: added ifndef/define/endif macros
3660 around the header file.
3661 Bug reported from Jesus Calvino-Fraga
3663 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3665 * sdcc.spec: updated
3666 * device/include/Makefile.in: don't install CVS directories
3667 * device/lib/Makefile.in: added removal of CVS directories after install
3668 * doc/Makefile: fixed install, added local_icons
3669 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3670 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3671 * src/ds390/gen.c (genRightShift): fixed bug #870788
3672 * src/SDCCast.c (decorateType): fixed bug #870781
3674 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3676 PIC16 port related changes:
3677 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3678 added variable stackPos,
3680 * gen.c: genCall, assignResultValue: added support for
3681 pushing/retrieving function parameters to/from stack,
3682 genFunction,genEndFunction: setup stack frame for the
3684 genAddrOf: will be changed according to bug 863624
3686 * added files genutils.c and genutils.h which contain gen*
3687 debugged and optimised functions extracted from gen.c
3689 * glue.c: added variable 'externs' which holds extern symbols,
3690 pic16emitRegularMap: is modified to properly handle relocatable
3691 symbols under the new scheme,
3692 pic16createInterruptVect: is modified
3693 pic16printPublics: is modified to emit 'global' assembler directives,
3694 added pic16_printExterns to print extern symbols,
3695 pic16glue: initializes stack/frame pointer in the beginning of
3696 the assembly output. Temporary hack, will be corrected later,
3697 because gplink yet does not support stack and SDCC does not
3698 yet support a type of crt0.o object to create the final binary.
3700 * Removed many lines that contain 8051 legacy code.
3701 * The code is finally placed under a 'code' directive.
3702 * Added port specific options.
3704 * _process_pragma: simplified since now we do not need *special*
3705 include file to define SFR registers. But a separate header
3706 will be needed. This will be developed later.
3707 * _pic16_parseOptions: added, parses port specific options:
3708 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3709 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3710 --preplace-udata-with=
3712 * _pic16_setDefaultOptions: modified to initialize section names,
3713 but hack is temporarly out of order since it needs improvement.
3714 * _pic16_genAssemblerPreamble: configuration words are emitted by
3715 their address instead of their name. This part is incomplete and
3716 supports only the 18Fxx2 devices. Other devices will emit an error
3717 during assembly since they do not contain the same set of config
3719 * _pic16_genIVT: is modified,
3721 * pcode.c: added definitions for some hardware registers that are needed
3723 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3724 All PCI entries are updated. Now LFSR is supported.
3725 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3726 * added pic16_newpCodeOpLit2 to support instructions with
3727 two literal arguments
3728 * pic16_pCode2str: corrected code that emits assembler instructions
3729 with two literal operands and those that have an access bit modifier
3730 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3731 this fixes a bug which caused some labels to be lost, when an
3732 assembler directive was added, i.e. banksel,
3733 * pic16_FixRegisterBanking: improved logic that causes the insertion
3735 * InlineFunction: functions that are called once, are not any more
3736 inlined. This can be a port option in the future,
3738 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3740 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3741 hold the corresponding uninitialized symbols,
3742 * pic16_allocProcessorRegister: registers have explicit marked the
3744 * pic16_allocInternalRegister: registers are explicit marked as
3746 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3747 processing list, so bit registers were lost,
3750 * ralloc.h: added field 'accessBank' and original symbol operand
3751 in register definition,
3752 * removed the field isMapped from register definition,
3754 ** Several functions have been removed from various sources:
3755 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3756 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3757 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3758 pic16_assignRelocatableRegisters
3760 ** others have been introduced:
3761 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3762 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3764 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3766 * support/scripts/inc2h.pl: changed definition of BIT_AT
3767 to emit 'sbit at' instead of 'bit at'. This was a request.
3769 PIC16 port related preliminary changes:
3770 * gen.c: prefixed function popRegFromString with
3771 pic16_ and all references to it corrected
3772 * pcode.c: all pic16_pc_* hardware registers prefixed
3773 with underscore (_),
3774 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3775 * ralloc.c: newReg(): when register is REG_SFR then
3776 set address to rIdx,
3777 pic16_allocProcessorRegister(): marks register wasUsed=0
3778 pic16_writeUsedRegs(): added a call to assign processor
3779 registers via pic16_assignFixedRegisters
3781 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3783 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3784 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3785 variables in unused register banks. Also the SSEG is placed
3786 wherever there is enough space for it, and IDATA can be anywhere
3787 in internal RAM. For now compile using -Wl-Y[stack_size].
3788 The mem file is different for this option as well, since it
3789 makes no sense of talking about DSEG lenght.
3791 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3793 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3794 in certain cases, e.g. when ROM assignment, patch provided
3795 from Albert den Haan.
3797 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3940 * src/mcs51/peephole.def,
3941 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3942 (allows non-interrupt and interrupt code to safely compete for a resource

3953 multiply defined with mismatching "at" address.
3955 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3957 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

4036 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4038 * src/SDCCast.c (decorateType): disabled a transformation I added in
4039 revision 1.188 (access to fields of a structure at an absolute address);
4040 it breaks with bitfields, extern declarations, and gcse analysis.
4041 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4042 could be assigned through a pointer, so don't complain.
4043 * src/SDCCast.c (astErrors),
4045 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4682 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4683 support for standard C idiom of memory mapped variables; for
4684 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4685 to xdata int at 0x1234 tempvar = 1.
4686 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4687 provided by Akiya ISHIDA

4703 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4705 Fixed bug #621531 (const & volatile confusion in the type chain).
4706 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4798 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4799 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4800 fetching of the pointer
4801 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4802 copied from genNearPointerSet()
4803 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4804 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4805 If they pop r0/r1 they must be called in the opposite order than aopOp().
4806 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4807 (resp. --stack-auto), prepared for --xstack

4818 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4820 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4821 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4822 type for bits was changed. It resulted in bit variables becoming
4823 global, which is not permitted in PIC 14 assembly output.
4825 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4827 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4840 A few small changes that speed up the peephole optimizer.
4844 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4846 Try to make the peephole optimizer smarter by maintaining
4847 an association between the assembly source code and the
4848 iCodes that originated them. Put this information to use
4849 with a new peephole rule condition "notVolatile" so that
4850 the rules can be aggressive yet still safe.
4855 * src/mcs51/peeph.def
4857 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4861 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4862 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4863 if the left or right operand symbols have the accuse flag set.
4865 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4867 Changed the type of the result of the ! (NOT) operator to char;
4868 previously it returned the same type as the source. This allows
4869 us to eliminate all the genFloatNot functions (all of its target
4870 implementations were very buggy) since !float can use the same
4873 * src/SDCCicode.c (ast2iCode): ! returns char

4880 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4882 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4883 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4884 during interrupts. Ensure WSAVE is located at a shared bank address.
4885 2. Fixed page selection in some places
4886 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4887 the registers name strings.
4888 4. Fixed "signed / unsigned compare" compiler warnings.
4889 5. The PIC port manages its own allocation of the general purpose
4890 registers, but makes no attempt to reuse them. As a result when
4891 compiling it soon runs out of general purpose registers. Some
4892 additional code was added to the files pcode.c and device.c to walk
4893 through the function call tree and rename the registers so that they
4903 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4904 genPlus() & genMinus() when the result is the same as left or right

4910 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4912 Made bitfield a distinct type from bit so that bitfields
4913 convert as per ANSI C and bits retain their traditional
4914 boolean style behaviour. Implemented bitfield support in
4922 * src/ds390/gen.c: bit v bitfield split
4923 * src/z80/gen.c: New support for bitfields
4924 * support/regression/tests/bitfields.c: reenabled z80,
4927 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4929 Rules 246.x, 247.x relate to bitfields, the others speed up
4930 access to xdata mapped I/O devices.
4932 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4934 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4936 Cleaned up genPackBits and genUnpackBits and added two helper
4937 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4938 for literal assignments in genPackBits (thanks to Frieder for
4944 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4946 Fixed bug #748310 (pointer to function type mishandled when the
4947 function name is omitted). Also fixed a SIGSEGV when a function
4948 attribute (reentrant, etc) is used on a non-function or on a
4949 function but misplaced before the parameter list.
4951 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4953 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4954 * support/Util/SDCCerr.h,
4955 * support/Util/SDCCerr.c: Added func attr misuse error msg

4976 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4978 Made the constant following the "interrupt" keyword optional. If
4979 omitted, the function will not automatically be given an entry
4980 in the interrupt vector table (similar to #pragma NOIV, but
4981 less syntacticly kludgy). The interrupt number is also now
4982 range checked. Also fixed a bug in the high order bit example

4996 * src/SDCCicode.c (operandOperation): rewritten some ops
4997 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4998 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5000 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5001 be re-activated by defining REDUCE_LITERALS)
5002 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5003 unsigned, but are signed by default
5004 * src/SDCCval.c (constVal): rearranged
5005 * src/SDCCval.c (valMod): preliminary fix
5006 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5048 constants are unsigned; added recognition of "u" flag for unsigned
5049 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5050 * src/SDCCval.c (valDiv, valMod): fixed signdness
5051 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5052 signedness of modulo, left and right shift

5512 added if/endif conditional macros to remove options help
5513 messages from optionsTable when a port is not configured, added
5514 support for the PIc16 port in the ports table, when executing
5515 the compiler with no port specified on command line, a default
5516 port is selected with the new macro DEFAULT_PORT which is
5517 defined in port.h, in setDefaultOptions() linkOptions is removed
5518 from initialization assignment, since now it is a set,
5519 parseCmdLine uses setParseWithComma for linkOptions, in
5520 linkEdit() linkOptions are accessed with new function indexSet()
5521 which returns the i'th item of a set variable. See SDCCset.c, in
5522 linkEdit() when calling buildCmdLine(), added linkOptions as
5523 last argument. Now users can pass arguments to gplink via the
5524 -Wl option, main() uses pic16glue() to glue up pic16 programs

5538 gpasm complaining and test the linkage with gplink, _linkCmd and
5539 _asmCmd changed to be more gplink and gpasm friendly
5540 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5541 produced an error when parsed, peep rule 12 is added to utilize
5542 movff, but it is commented out since the pCode does not support
5543 yet a command with 2 address arguments
5545 2003-05-18 <johan AT balder>
5547 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6562 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
6563 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6565 2003-01-07 <johan AT balder>
6567 * src/SDCCast.c (decorateType): fixed bug #600035
6569 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6570 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6580 2003-01-06 <johan AT balder>
6582 * src/SDCCicode.c: fixed array add
6584 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6585 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6586 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6588 2003-01-04 <johan AT balder>
6590 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6592 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6593 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6595 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6596 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6597 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6599 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6600 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6602 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6603 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6605 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6606 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6608 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6610 * in \sdcc\as\mcs51\ changed these files in order to create an
6611 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6612 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6613 following files to include the previous two files: aslink.dsp,
6614 Makefile.aslink, Makefile.bcc, and Makefile.in.
6616 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6617 .adb instead of .cdb
6619 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6621 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6622 value from option --iram-size.
6624 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6626 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6629 2002-09-18 <wiml AT hhhh.org>
6631 * SDCClrange.h: exposed setFromRange() and setToRange()
6632 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6633 packRegsForAccUse() (bug 542397)
6634 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6635 multiple times and emitting the fetch operations more than once
6636 added aopGetUsesAcc() function to allow binary operators to
6637 fetch their operands in the correct order; made genMinus() emit
6638 compact code for X = LITERAL - Y
6640 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6641 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6642 sprintf() in line 1267.
6644 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6645 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6648 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6649 Changes to aslink (All the changes are marked with 'JCF'):
6651 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6654 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6655 area BSEG. Also moves, if possible, the DATA area down into the internal
6656 ram so more space is available.
6658 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6661 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6662 not bytes. Function summary() which creates a memory usage summary
6663 file with extension .mem. Reports of overlaping stack and small stack
6664 size. If the space for the stack is less than 16 bytes aslink trows a
6667 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6668 the 8051. Option 'y' for memory summary output file.
6670 Changes to sdcc (All the changes are marked with 'JCF'):
6672 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6674 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6675 overlaying area for it (uses RegBankUsed[4]).
6677 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6678 bank zero as used by default. By default aslink locates the stack
6679 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6680 the creation of the .mem file. Delegates the allocation of data area
6681 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6682 the begining of the stack area to aslink.
6684 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6685 glue() in SDCCglue.c creates an area for it.
6687 2002-09-03 Borut Razem <borut.razem AT siol.net>
6688 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6689 sdcc/src/pic/glue.c:
6690 introduced atexit() handler for teporay files removal in case of
6691 errors, assertions, ...
6693 2002-08-29 Borut Razem <borut.razem AT siol.net>
6694 * sdcc/support/cpp2/auto-host_vc_in.h:
6695 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6696 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6697 Maybe there is a similar problem with BORLANDC? It should be checked!
6699 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6700 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6701 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6702 was not executed, and the compiler (cl) launched a warning:
6703 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6705 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6706 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6708 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6709 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6711 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6712 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6713 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6714 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6715 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6716 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6717 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6718 - added Release configuration in VS projects
6719 - review of compiler an linker options
6720 - VC .exe files are generated in bin_vc directory, not to interfere
6721 with binaries generated from other projects (cygwin, mingw, bcc ...)
6723 * sdcc/src/yacc.dsp: added
6725 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6726 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6727 and insert the version number definitions from .version
6729 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6731 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6732 added - genarate auto-host.h using auto-host_vc_in.h as template
6735 removed from CVS, generated automatically
6737 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6738 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6740 2002-08-11 Borut Razem <borut.razem AT siol.net>
6741 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6743 2002-08-10 Borut Razem <borut.razem AT siol.net>
6744 * src/SDCCmain.c (main):
6745 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6746 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6747 The consequence was that some temporary files were not removed.
6750 unification of code in functions tempfilename() and tempfile():
6751 function tempnam() is defined in Visual Studio 6.0 and .NET
6753 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6755 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6756 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6757 - removed compiler command line option /WX: Treats all warnings as errors
6758 - update a list of source files, included into the project
6760 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6761 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6762 changed project type to Generic Project so that can be correcly converted to VS.NET project
6764 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6766 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6768 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6770 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6771 added return 0 statements after assert() to make compiler happy
6773 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6774 added newline in the def file to keep MSC compiler satisfied
6776 * sdcc/src/z80/gen.c:
6777 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6778 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6779 - solved MSC error in function aopDump()
6781 * sdcc_vc.h: define PREFIX as "\\sdcc"
6783 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6784 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6787 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6788 - Rewrote the register banking algorithm.
6789 - Added pCode live-range analysis to registers (for now, only non-used and
6790 singly-used registers optimized away)
6792 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6794 * 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.

6821 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6823 2002-03-28 Johan Knol <johan AT balder>
6825 * src/SDCCval.c: fixed bug #532436
6827 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6829 Added "char *Processor" field to the port structure.
6832 Added -p option. Allows port dependent processor to be specified.
6835 Initialized the new field char *Processor field to NULL in all ports
6838 Compiler generated registers for interrupt context saving
6839 were not getting allocated.
6841 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6844 Fixed left shift. Will promote the left side of a left shift
6845 if a) left shifting more than size of operand or b) when assigned
6846 to something size > size of left side
6848 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6850 tons of changes. Register allocation has been
6851 rewritten. Added customization for the various PICs. Flow
6852 analysis is restructured. ...
6858 Added. device.c is a PIC port hack to accomodate variations
6861 2002-03-13 Michael Hope <michaelh AT vroom>
6863 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6865 2002-03-04 johanknol <johanknol AT manik>

6872 2002-03-04 bela <bela AT manik>
6874 * /device/include/mcs51reg.h:
6875 ds89c420 register definition update
6877 2002-03-03 <johan AT FRIJA>

6956 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6958 * sdcc/src/SDCCloop.c:
6959 Previous fix was not good. basic blocks that have "break" or "return" are
6960 not really partof a loop , but live ranges used in these blocks should
6961 be live thru the entire loop, so set partOfLoop but don't add them to
6964 2002-02-21 <johan AT FRIJA>
6966 * src/SDCCcse.c: fixed bug #514308
6968 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6971 Fixed BUG #519583. If a conditional block ended in a return/break
6972 statement inside a loop, it was not being considered part of the loop.
6974 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6976 2002-02-10 Karl Bongers <karl AT turbobit.com>
6979 Fixed up SDCDB debugger somewhat. Updated debugger/README
6980 with lots of comments and notes.
6982 * device/examples/test2.c:
6983 Fix bug, "red" variable not being initialized(compiler complained).
6985 * device/examples/Makefile, examples/test3.c:
6986 Add Makefile in device/examples folder, compiles test3.c
6987 for use as a multiple module SDCDB test case.
6989 * sim/ucsim/cmd.src/cmdset.cc:
6990 Took out debug printfs in ucsim "next" command.
6993 Karl and Johan start ucsim XA support. Most dissassembly working,
6994 about 75% emulation done(plenty of work remaining).
6996 * sim/ucsim/z80.src:
6997 Add Z80 support to ucsim, add test-ucz80 regression test,
6998 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6999 Notice z80 compiler fails on examples/test3.c/crc code.
7001 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7003 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7004 Added support for --parms-in-bank1
7006 * src/ds390/peeph.def:
7007 added a few more peephole optimzations
7010 1) added __builtin_inp & __builtin_outp used to read in data of given length
7011 from a memory mapped port
7012 2) added __builtin_memcmp
7013 3) added __builtin_swapw swap bytes of a short
7015 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7016 1) handle multiple send & receives from register bank1
7017 2) ralloc can now allocate DPTR1 to some liveRanges
7019 * src/SDCCsymt.c, src/SDCCsymt.h:
7020 changes to handle multiple sends & receives
7023 added some pointer arithmetic optimization
7026 added some pointer arithmetic optimizations but not stable yet so not
7027 called from anywhere (will get this working shortly)
7029 * src/SDCCopt.c: fixed for multiple sends & receives
7032 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7033 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7034 set preprocessor defines (depending on options)
7036 * src/SDCCicode.c, src/SDCCicode.h:
