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

3351 loaded with the linker search paths (-L arguments) and the libraries
3352 to be linked with the current source (-l arguments). Changes
3353 currently will affect only the pic16 port.
3354 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3355 include path the port specific paths and port specific libraries,
3356 * gplink command now contains the $3 argument,

3374 Documenting changes from previous commits.
3375 * configure.in (version 1.56),
3376 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3377 when generating output files to configure the pic16 library,
3378 but now I've commented it out, since gputils aren't installed in the
3379 SF compile farm, so library won't compile
3381 * device/lib/Makefile.in (version 1.56): initially I've added in
3382 target 'all' the prerequestive 'model-pic16' so it compiled the
3383 pic16 library, but now I've commented it out for the same reasons
3385 * added targets 'model-pic16' and 'objects-pic16' to compile the
3387 * added target 'port-specific-objects-pic16' to handle the
3388 generated libraries and copy them into the build/ directory
3389 * added target 'clean-intermediate-pic16' to clean intermediate
3390 files into pic16 directory
3391 * in target 'installdirs' added line to create directory pic16 in

3636 * src/SDCCast.c (decorateType),
3637 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3638 LEFT_OP (left shift)
3640 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3642 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3643 (default behaviour).
3645 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3647 A python script to validate compiler diagnostic messages. It can be
3648 used to verify that sdcc complains about bad c source code and
3649 gives a good location of the error.
3650 * support/valdiag/Makefile,
3651 * support/valdiag/valdiag.py,
3652 * support/valdiag/tests/*

3665 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3667 * src/common.h: added ifndef/define/endif macros
3668 around the header file.
3669 Bug reported from Jesus Calvino-Fraga
3671 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3673 * sdcc.spec: updated
3674 * device/include/Makefile.in: don't install CVS directories
3675 * device/lib/Makefile.in: added removal of CVS directories after install
3676 * doc/Makefile: fixed install, added local_icons
3677 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3678 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3679 * src/ds390/gen.c (genRightShift): fixed bug #870788
3680 * src/SDCCast.c (decorateType): fixed bug #870781
3682 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3684 PIC16 port related changes:
3685 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3686 added variable stackPos,
3688 * gen.c: genCall, assignResultValue: added support for
3689 pushing/retrieving function parameters to/from stack,
3690 genFunction,genEndFunction: setup stack frame for the
3692 genAddrOf: will be changed according to bug 863624
3694 * added files genutils.c and genutils.h which contain gen*
3695 debugged and optimised functions extracted from gen.c
3697 * glue.c: added variable 'externs' which holds extern symbols,
3698 pic16emitRegularMap: is modified to properly handle relocatable
3699 symbols under the new scheme,
3700 pic16createInterruptVect: is modified
3701 pic16printPublics: is modified to emit 'global' assembler directives,
3702 added pic16_printExterns to print extern symbols,
3703 pic16glue: initializes stack/frame pointer in the beginning of
3704 the assembly output. Temporary hack, will be corrected later,
3705 because gplink yet does not support stack and SDCC does not
3706 yet support a type of crt0.o object to create the final binary.
3708 * Removed many lines that contain 8051 legacy code.
3709 * The code is finally placed under a 'code' directive.
3710 * Added port specific options.
3712 * _process_pragma: simplified since now we do not need *special*
3713 include file to define SFR registers. But a separate header
3714 will be needed. This will be developed later.
3715 * _pic16_parseOptions: added, parses port specific options:
3716 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3717 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3718 --preplace-udata-with=
3720 * _pic16_setDefaultOptions: modified to initialize section names,
3721 but hack is temporarly out of order since it needs improvement.
3722 * _pic16_genAssemblerPreamble: configuration words are emitted by
3723 their address instead of their name. This part is incomplete and
3724 supports only the 18Fxx2 devices. Other devices will emit an error
3725 during assembly since they do not contain the same set of config
3727 * _pic16_genIVT: is modified,
3729 * pcode.c: added definitions for some hardware registers that are needed
3731 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3732 All PCI entries are updated. Now LFSR is supported.
3733 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3734 * added pic16_newpCodeOpLit2 to support instructions with
3735 two literal arguments
3736 * pic16_pCode2str: corrected code that emits assembler instructions
3737 with two literal operands and those that have an access bit modifier
3738 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3739 this fixes a bug which caused some labels to be lost, when an
3740 assembler directive was added, i.e. banksel,
3741 * pic16_FixRegisterBanking: improved logic that causes the insertion
3743 * InlineFunction: functions that are called once, are not any more
3744 inlined. This can be a port option in the future,
3746 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3748 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3749 hold the corresponding uninitialized symbols,
3750 * pic16_allocProcessorRegister: registers have explicit marked the
3752 * pic16_allocInternalRegister: registers are explicit marked as
3754 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3755 processing list, so bit registers were lost,
3758 * ralloc.h: added field 'accessBank' and original symbol operand
3759 in register definition,
3760 * removed the field isMapped from register definition,
3762 ** Several functions have been removed from various sources:
3763 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3764 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3765 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3766 pic16_assignRelocatableRegisters
3768 ** others have been introduced:
3769 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3770 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3772 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3774 * support/scripts/inc2h.pl: changed definition of BIT_AT
3775 to emit 'sbit at' instead of 'bit at'. This was a request.
3777 PIC16 port related preliminary changes:
3778 * gen.c: prefixed function popRegFromString with
3779 pic16_ and all references to it corrected
3780 * pcode.c: all pic16_pc_* hardware registers prefixed
3781 with underscore (_),
3782 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3783 * ralloc.c: newReg(): when register is REG_SFR then
3784 set address to rIdx,
3785 pic16_allocProcessorRegister(): marks register wasUsed=0
3786 pic16_writeUsedRegs(): added a call to assign processor
3787 registers via pic16_assignFixedRegisters
3789 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3791 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3792 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3793 variables in unused register banks. Also the SSEG is placed
3794 wherever there is enough space for it, and IDATA can be anywhere
3795 in internal RAM. For now compile using -Wl-Y[stack_size].
3796 The mem file is different for this option as well, since it
3797 makes no sense of talking about DSEG lenght.
3799 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3801 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3802 in certain cases, e.g. when ROM assignment, patch provided
3803 from Albert den Haan.
3805 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4044 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4046 * src/SDCCast.c (decorateType): disabled a transformation I added in
4047 revision 1.188 (access to fields of a structure at an absolute address);
4048 it breaks with bitfields, extern declarations, and gcse analysis.
4049 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4050 could be assigned through a pointer, so don't complain.
4051 * src/SDCCast.c (astErrors),
4053 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4690 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4691 support for standard C idiom of memory mapped variables; for
4692 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4693 to xdata int at 0x1234 tempvar = 1.
4694 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4695 provided by Akiya ISHIDA

4711 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4713 Fixed bug #621531 (const & volatile confusion in the type chain).
4714 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4806 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4807 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4808 fetching of the pointer
4809 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4810 copied from genNearPointerSet()
4811 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4812 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4813 If they pop r0/r1 they must be called in the opposite order than aopOp().
4814 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4815 (resp. --stack-auto), prepared for --xstack

4826 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4828 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4829 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4830 type for bits was changed. It resulted in bit variables becoming
4831 global, which is not permitted in PIC 14 assembly output.
4833 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4835 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4848 A few small changes that speed up the peephole optimizer.
4852 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4854 Try to make the peephole optimizer smarter by maintaining
4855 an association between the assembly source code and the
4856 iCodes that originated them. Put this information to use
4857 with a new peephole rule condition "notVolatile" so that
4858 the rules can be aggressive yet still safe.
4863 * src/mcs51/peeph.def
4865 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4869 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4870 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4871 if the left or right operand symbols have the accuse flag set.
4873 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4875 Changed the type of the result of the ! (NOT) operator to char;
4876 previously it returned the same type as the source. This allows
4877 us to eliminate all the genFloatNot functions (all of its target
4878 implementations were very buggy) since !float can use the same
4881 * src/SDCCicode.c (ast2iCode): ! returns char

4890 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4891 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4892 during interrupts. Ensure WSAVE is located at a shared bank address.
4893 2. Fixed page selection in some places
4894 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4895 the registers name strings.
4896 4. Fixed "signed / unsigned compare" compiler warnings.
4897 5. The PIC port manages its own allocation of the general purpose
4898 registers, but makes no attempt to reuse them. As a result when
4899 compiling it soon runs out of general purpose registers. Some
4900 additional code was added to the files pcode.c and device.c to walk
4901 through the function call tree and rename the registers so that they
4911 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4912 genPlus() & genMinus() when the result is the same as left or right
4914 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4918 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4920 Made bitfield a distinct type from bit so that bitfields
4921 convert as per ANSI C and bits retain their traditional
4922 boolean style behaviour. Implemented bitfield support in
4930 * src/ds390/gen.c: bit v bitfield split
4931 * src/z80/gen.c: New support for bitfields
4932 * support/regression/tests/bitfields.c: reenabled z80,
4935 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4937 Rules 246.x, 247.x relate to bitfields, the others speed up
4938 access to xdata mapped I/O devices.
4940 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4942 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4944 Cleaned up genPackBits and genUnpackBits and added two helper
4945 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4946 for literal assignments in genPackBits (thanks to Frieder for
4952 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4954 Fixed bug #748310 (pointer to function type mishandled when the
4955 function name is omitted). Also fixed a SIGSEGV when a function
4956 attribute (reentrant, etc) is used on a non-function or on a
4957 function but misplaced before the parameter list.
4959 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4961 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4962 * support/Util/SDCCerr.h,
4963 * support/Util/SDCCerr.c: Added func attr misuse error msg

4984 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4986 Made the constant following the "interrupt" keyword optional. If
4987 omitted, the function will not automatically be given an entry
4988 in the interrupt vector table (similar to #pragma NOIV, but
4989 less syntacticly kludgy). The interrupt number is also now
4990 range checked. Also fixed a bug in the high order bit example

5004 * src/SDCCicode.c (operandOperation): rewritten some ops
5005 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5006 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5008 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5009 be re-activated by defining REDUCE_LITERALS)
5010 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5011 unsigned, but are signed by default
5012 * src/SDCCval.c (constVal): rearranged
5013 * src/SDCCval.c (valMod): preliminary fix
5014 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5056 constants are unsigned; added recognition of "u" flag for unsigned
5057 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5058 * src/SDCCval.c (valDiv, valMod): fixed signdness

5520 added if/endif conditional macros to remove options help
5521 messages from optionsTable when a port is not configured, added
5522 support for the PIc16 port in the ports table, when executing
5523 the compiler with no port specified on command line, a default
5524 port is selected with the new macro DEFAULT_PORT which is
5525 defined in port.h, in setDefaultOptions() linkOptions is removed
5526 from initialization assignment, since now it is a set,
5527 parseCmdLine uses setParseWithComma for linkOptions, in
5528 linkEdit() linkOptions are accessed with new function indexSet()
5529 which returns the i'th item of a set variable. See SDCCset.c, in
5530 linkEdit() when calling buildCmdLine(), added linkOptions as
5531 last argument. Now users can pass arguments to gplink via the
5532 -Wl option, main() uses pic16glue() to glue up pic16 programs

5546 gpasm complaining and test the linkage with gplink, _linkCmd and
5547 _asmCmd changed to be more gplink and gpasm friendly
5548 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5549 produced an error when parsed, peep rule 12 is added to utilize
5550 movff, but it is commented out since the pCode does not support
5551 yet a command with 2 address arguments
5553 2003-05-18 <johan AT balder>
5555 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5582 2003-05-11 Borut Razem <borut.razem AT siol.net>
5584 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6570 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
6571 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6573 2003-01-07 <johan AT balder>
6575 * src/SDCCast.c (decorateType): fixed bug #600035
6577 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6578 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6588 2003-01-06 <johan AT balder>
6590 * src/SDCCicode.c: fixed array add
6592 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6593 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6594 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6596 2003-01-04 <johan AT balder>
6598 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6600 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6601 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6603 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6604 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6605 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6607 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6608 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6610 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6611 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6613 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6614 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6616 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6618 * in \sdcc\as\mcs51\ changed these files in order to create an
6619 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6620 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6621 following files to include the previous two files: aslink.dsp,
6622 Makefile.aslink, Makefile.bcc, and Makefile.in.
6624 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6625 .adb instead of .cdb
6627 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6629 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6630 value from option --iram-size.
6632 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6634 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6637 2002-09-18 <wiml AT hhhh.org>
6639 * SDCClrange.h: exposed setFromRange() and setToRange()
6640 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6641 packRegsForAccUse() (bug 542397)
6642 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6643 multiple times and emitting the fetch operations more than once
6644 added aopGetUsesAcc() function to allow binary operators to
6645 fetch their operands in the correct order; made genMinus() emit
6646 compact code for X = LITERAL - Y
6648 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6649 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6650 sprintf() in line 1267.
6652 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6653 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6656 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6657 Changes to aslink (All the changes are marked with 'JCF'):
6659 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6662 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6663 area BSEG. Also moves, if possible, the DATA area down into the internal
6664 ram so more space is available.
6666 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6669 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6670 not bytes. Function summary() which creates a memory usage summary
6671 file with extension .mem. Reports of overlaping stack and small stack
6672 size. If the space for the stack is less than 16 bytes aslink trows a
6675 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6676 the 8051. Option 'y' for memory summary output file.
6678 Changes to sdcc (All the changes are marked with 'JCF'):
6680 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6682 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6683 overlaying area for it (uses RegBankUsed[4]).
6685 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6686 bank zero as used by default. By default aslink locates the stack
6687 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6688 the creation of the .mem file. Delegates the allocation of data area
6689 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6690 the begining of the stack area to aslink.
6692 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6693 glue() in SDCCglue.c creates an area for it.
6695 2002-09-03 Borut Razem <borut.razem AT siol.net>
6696 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6697 sdcc/src/pic/glue.c:
6698 introduced atexit() handler for teporay files removal in case of
6699 errors, assertions, ...
6701 2002-08-29 Borut Razem <borut.razem AT siol.net>
6702 * sdcc/support/cpp2/auto-host_vc_in.h:
6703 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6704 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6705 Maybe there is a similar problem with BORLANDC? It should be checked!
6707 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6708 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6709 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6710 was not executed, and the compiler (cl) launched a warning:
6711 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6713 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6714 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6716 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6717 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6719 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6720 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6721 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6722 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6723 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6724 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6725 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6726 - added Release configuration in VS projects
6727 - review of compiler an linker options
6728 - VC .exe files are generated in bin_vc directory, not to interfere
6729 with binaries generated from other projects (cygwin, mingw, bcc ...)
6731 * sdcc/src/yacc.dsp: added
6733 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6734 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6735 and insert the version number definitions from .version
6737 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6739 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6740 added - genarate auto-host.h using auto-host_vc_in.h as template
6743 removed from CVS, generated automatically
6745 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6746 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6748 2002-08-11 Borut Razem <borut.razem AT siol.net>
6749 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6751 2002-08-10 Borut Razem <borut.razem AT siol.net>
6752 * src/SDCCmain.c (main):
6753 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6754 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6755 The consequence was that some temporary files were not removed.
6758 unification of code in functions tempfilename() and tempfile():
6759 function tempnam() is defined in Visual Studio 6.0 and .NET
6761 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6763 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6764 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6765 - removed compiler command line option /WX: Treats all warnings as errors
6766 - update a list of source files, included into the project
6768 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6769 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6770 changed project type to Generic Project so that can be correcly converted to VS.NET project
6772 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6774 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6776 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6778 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6779 added return 0 statements after assert() to make compiler happy
6781 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6782 added newline in the def file to keep MSC compiler satisfied
6784 * sdcc/src/z80/gen.c:
6785 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6786 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6787 - solved MSC error in function aopDump()
6789 * sdcc_vc.h: define PREFIX as "\\sdcc"
6791 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6792 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6795 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6796 - Rewrote the register banking algorithm.
6797 - Added pCode live-range analysis to registers (for now, only non-used and
6798 singly-used registers optimized away)
6800 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6802 * 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.

6827 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6829 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6831 2002-03-28 Johan Knol <johan AT balder>
6833 * src/SDCCval.c: fixed bug #532436
6835 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6837 Added "char *Processor" field to the port structure.
6840 Added -p option. Allows port dependent processor to be specified.
6843 Initialized the new field char *Processor field to NULL in all ports
6846 Compiler generated registers for interrupt context saving
6847 were not getting allocated.
6849 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6852 Fixed left shift. Will promote the left side of a left shift
6853 if a) left shifting more than size of operand or b) when assigned
6854 to something size > size of left side
6856 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6858 tons of changes. Register allocation has been
6859 rewritten. Added customization for the various PICs. Flow
6860 analysis is restructured. ...
6866 Added. device.c is a PIC port hack to accomodate variations
6869 2002-03-13 Michael Hope <michaelh AT vroom>
6871 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6873 2002-03-04 johanknol <johanknol AT manik>
6875 * /src/SDCCval.c: fixed
6877 const unsigned char arr[][2] = { { 0, 1 } };
6878 t18.c:1: error: Initializer element is not constant
6880 2002-03-04 bela <bela AT manik>
6882 * /device/include/mcs51reg.h:
6883 ds89c420 register definition update
6885 2002-03-03 <johan AT FRIJA>

6964 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6966 * sdcc/src/SDCCloop.c:
6967 Previous fix was not good. basic blocks that have "break" or "return" are
6968 not really partof a loop , but live ranges used in these blocks should
6969 be live thru the entire loop, so set partOfLoop but don't add them to
6972 2002-02-21 <johan AT FRIJA>
6974 * src/SDCCcse.c: fixed bug #514308
6976 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6979 Fixed BUG #519583. If a conditional block ended in a return/break
6980 statement inside a loop, it was not being considered part of the loop.
6982 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6984 2002-02-10 Karl Bongers <karl AT turbobit.com>
6987 Fixed up SDCDB debugger somewhat. Updated debugger/README
6988 with lots of comments and notes.
6990 * device/examples/test2.c:
6991 Fix bug, "red" variable not being initialized(compiler complained).
6993 * device/examples/Makefile, examples/test3.c:
6994 Add Makefile in device/examples folder, compiles test3.c
6995 for use as a multiple module SDCDB test case.
6997 * sim/ucsim/cmd.src/cmdset.cc:
6998 Took out debug printfs in ucsim "next" command.
7001 Karl and Johan start ucsim XA support. Most dissassembly working,
7002 about 75% emulation done(plenty of work remaining).
7004 * sim/ucsim/z80.src:
7005 Add Z80 support to ucsim, add test-ucz80 regression test,
7006 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7007 Notice z80 compiler fails on examples/test3.c/crc code.
7009 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7011 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7012 Added support for --parms-in-bank1
7014 * src/ds390/peeph.def:
7015 added a few more peephole optimzations
7018 1) added __builtin_inp & __builtin_outp used to read in data of given length
7019 from a memory mapped port
7020 2) added __builtin_memcmp
7021 3) added __builtin_swapw swap bytes of a short
7023 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7024 1) handle multiple send & receives from register bank1
7025 2) ralloc can now allocate DPTR1 to some liveRanges
7027 * src/SDCCsymt.c, src/SDCCsymt.h:
7028 changes to handle multiple sends & receives
7031 added some pointer arithmetic optimization
7034 added some pointer arithmetic optimizations but not stable yet so not
7035 called from anywhere (will get this working shortly)
7037 * src/SDCCopt.c: fixed for multiple sends & receives
7040 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7041 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7042 set preprocessor defines (depending on options)
