357 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
359 * (genCast): began a fix to optimize the casting of a bit to another

3386 loaded with the linker search paths (-L arguments) and the libraries
3387 to be linked with the current source (-l arguments). Changes
3388 currently will affect only the pic16 port.
3389 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3390 include path the port specific paths and port specific libraries,
3391 * gplink command now contains the $3 argument,
3392 * src/pic16/device.h,
3393 * src/pic16/device.c,: structure PIC_device is made public and
3394 renamed to PIC16_device, the same for variable Pics which is renamed

3409 Documenting changes from previous commits.
3410 * configure.in (version 1.56),
3411 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3412 when generating output files to configure the pic16 library,
3413 but now I've commented it out, since gputils aren't installed in the
3414 SF compile farm, so library won't compile
3416 * device/lib/Makefile.in (version 1.56): initially I've added in
3417 target 'all' the prerequestive 'model-pic16' so it compiled the
3418 pic16 library, but now I've commented it out for the same reasons
3420 * added targets 'model-pic16' and 'objects-pic16' to compile the
3422 * added target 'port-specific-objects-pic16' to handle the
3423 generated libraries and copy them into the build/ directory
3424 * added target 'clean-intermediate-pic16' to clean intermediate
3425 files into pic16 directory
3426 * in target 'installdirs' added line to create directory pic16 in

3614 structure to inform whether to create a .lnk file or not,
3622 * src/z80/main.c: changed appropriately to configure
3623 needLinkerScript flag
3625 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3626 * src/pic/glue.c: added variable udata_section_name to

3637 arguments via -W option
3638 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3639 object file from '.rel' to '.o' in port->linker structure,
3640 changed size of fptr from 2 to 3 in port structure
3642 2004-01-07 Borut Razem <borut.razem AT siol.net>
3644 * support/scripts/sdcc.nsi: update PATH
3645 * support/scripts/sdcc.ico: craeted

3661 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3663 * as/mcs51/lkmain.c: Help about -Y option
3664 * as/mcs51/lkarea.c: Fixed gcc warnings
3666 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

3670 * support/valdiag/tests/overflow.c: added
3671 * src/SDCCast.c (decorateType),
3672 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3673 LEFT_OP (left shift)
3675 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3677 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3678 (default behaviour).
3680 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3682 A python script to validate compiler diagnostic messages. It can be
3683 used to verify that sdcc complains about bad c source code and
3684 gives a good location of the error.
3685 * support/valdiag/Makefile,
3686 * support/valdiag/valdiag.py,
3687 * support/valdiag/tests/*
3689 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3691 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3700 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3702 * src/common.h: added ifndef/define/endif macros
3703 around the header file.
3704 Bug reported from Jesus Calvino-Fraga
3706 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3708 * sdcc.spec: updated
3709 * device/include/Makefile.in: don't install CVS directories
3710 * device/lib/Makefile.in: added removal of CVS directories after install
3711 * doc/Makefile: fixed install, added local_icons
3712 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3713 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3714 * src/ds390/gen.c (genRightShift): fixed bug #870788
3715 * src/SDCCast.c (decorateType): fixed bug #870781
3717 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3719 PIC16 port related changes:
3720 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3721 added variable stackPos,
3723 * gen.c: genCall, assignResultValue: added support for
3724 pushing/retrieving function parameters to/from stack,
3725 genFunction,genEndFunction: setup stack frame for the
3727 genAddrOf: will be changed according to bug 863624
3729 * added files genutils.c and genutils.h which contain gen*
3730 debugged and optimised functions extracted from gen.c
3732 * glue.c: added variable 'externs' which holds extern symbols,
3733 pic16emitRegularMap: is modified to properly handle relocatable
3734 symbols under the new scheme,
3735 pic16createInterruptVect: is modified
3736 pic16printPublics: is modified to emit 'global' assembler directives,
3737 added pic16_printExterns to print extern symbols,
3738 pic16glue: initializes stack/frame pointer in the beginning of
3739 the assembly output. Temporary hack, will be corrected later,
3740 because gplink yet does not support stack and SDCC does not
3741 yet support a type of crt0.o object to create the final binary.
3743 * Removed many lines that contain 8051 legacy code.
3744 * The code is finally placed under a 'code' directive.
3745 * Added port specific options.
3747 * _process_pragma: simplified since now we do not need *special*
3748 include file to define SFR registers. But a separate header
3749 will be needed. This will be developed later.
3750 * _pic16_parseOptions: added, parses port specific options:
3751 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3752 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3753 --preplace-udata-with=
3755 * _pic16_setDefaultOptions: modified to initialize section names,
3756 but hack is temporarly out of order since it needs improvement.
3757 * _pic16_genAssemblerPreamble: configuration words are emitted by
3758 their address instead of their name. This part is incomplete and
3759 supports only the 18Fxx2 devices. Other devices will emit an error
3760 during assembly since they do not contain the same set of config
3762 * _pic16_genIVT: is modified,
3764 * pcode.c: added definitions for some hardware registers that are needed
3766 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3767 All PCI entries are updated. Now LFSR is supported.
3768 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3769 * added pic16_newpCodeOpLit2 to support instructions with
3770 two literal arguments
3771 * pic16_pCode2str: corrected code that emits assembler instructions
3772 with two literal operands and those that have an access bit modifier
3773 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3774 this fixes a bug which caused some labels to be lost, when an
3775 assembler directive was added, i.e. banksel,
3776 * pic16_FixRegisterBanking: improved logic that causes the insertion
3778 * InlineFunction: functions that are called once, are not any more
3779 inlined. This can be a port option in the future,
3781 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3783 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3784 hold the corresponding uninitialized symbols,
3785 * pic16_allocProcessorRegister: registers have explicit marked the
3787 * pic16_allocInternalRegister: registers are explicit marked as
3789 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3790 processing list, so bit registers were lost,
3793 * ralloc.h: added field 'accessBank' and original symbol operand
3794 in register definition,
3795 * removed the field isMapped from register definition,
3797 ** Several functions have been removed from various sources:
3798 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3799 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3800 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3801 pic16_assignRelocatableRegisters
3803 ** others have been introduced:
3804 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3805 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3807 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3809 * support/scripts/inc2h.pl: changed definition of BIT_AT
3810 to emit 'sbit at' instead of 'bit at'. This was a request.
3812 PIC16 port related preliminary changes:
3813 * gen.c: prefixed function popRegFromString with
3814 pic16_ and all references to it corrected
3815 * pcode.c: all pic16_pc_* hardware registers prefixed
3816 with underscore (_),
3817 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3818 * ralloc.c: newReg(): when register is REG_SFR then
3819 set address to rIdx,
3820 pic16_allocProcessorRegister(): marks register wasUsed=0
3821 pic16_writeUsedRegs(): added a call to assign processor
3822 registers via pic16_assignFixedRegisters
3824 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3826 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3827 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3828 variables in unused register banks. Also the SSEG is placed
3829 wherever there is enough space for it, and IDATA can be anywhere
3830 in internal RAM. For now compile using -Wl-Y[stack_size].
3831 The mem file is different for this option as well, since it
3832 makes no sense of talking about DSEG lenght.
3834 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3836 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3837 in certain cases, e.g. when ROM assignment, patch provided
3838 from Albert den Haan.

4079 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4081 * src/SDCCast.c (decorateType): disabled a transformation I added in
4082 revision 1.188 (access to fields of a structure at an absolute address);
4083 it breaks with bitfields, extern declarations, and gcse analysis.
4084 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4085 could be assigned through a pointer, so don't complain.

4725 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4726 support for standard C idiom of memory mapped variables; for
4727 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4728 to xdata int at 0x1234 tempvar = 1.
4729 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4730 provided by Akiya ISHIDA

4746 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4748 Fixed bug #621531 (const & volatile confusion in the type chain).
4749 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4841 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4842 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4843 fetching of the pointer
4844 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4845 copied from genNearPointerSet()
4846 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4847 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4848 If they pop r0/r1 they must be called in the opposite order than aopOp().
4849 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4850 (resp. --stack-auto), prepared for --xstack

4863 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4864 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4865 type for bits was changed. It resulted in bit variables becoming
4866 global, which is not permitted in PIC 14 assembly output.
4868 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4883 A few small changes that speed up the peephole optimizer.
4887 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4889 Try to make the peephole optimizer smarter by maintaining
4890 an association between the assembly source code and the
4891 iCodes that originated them. Put this information to use
4892 with a new peephole rule condition "notVolatile" so that
4893 the rules can be aggressive yet still safe.
4898 * src/mcs51/peeph.def
4900 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4904 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4905 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4906 if the left or right operand symbols have the accuse flag set.
4908 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4910 Changed the type of the result of the ! (NOT) operator to char;
4911 previously it returned the same type as the source. This allows
4912 us to eliminate all the genFloatNot functions (all of its target
4913 implementations were very buggy) since !float can use the same
4916 * src/SDCCicode.c (ast2iCode): ! returns char

4925 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4926 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4927 during interrupts. Ensure WSAVE is located at a shared bank address.
4928 2. Fixed page selection in some places
4929 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4930 the registers name strings.
4931 4. Fixed "signed / unsigned compare" compiler warnings.
4932 5. The PIC port manages its own allocation of the general purpose
4933 registers, but makes no attempt to reuse them. As a result when
4934 compiling it soon runs out of general purpose registers. Some
4935 additional code was added to the files pcode.c and device.c to walk
4936 through the function call tree and rename the registers so that they
4946 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4947 genPlus() & genMinus() when the result is the same as left or right

4953 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4955 Made bitfield a distinct type from bit so that bitfields
4956 convert as per ANSI C and bits retain their traditional
4957 boolean style behaviour. Implemented bitfield support in
4965 * src/ds390/gen.c: bit v bitfield split
4966 * src/z80/gen.c: New support for bitfields
4967 * support/regression/tests/bitfields.c: reenabled z80,
4970 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4972 Rules 246.x, 247.x relate to bitfields, the others speed up
4973 access to xdata mapped I/O devices.
4975 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4977 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4979 Cleaned up genPackBits and genUnpackBits and added two helper
4980 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4981 for literal assignments in genPackBits (thanks to Frieder for
4987 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4989 Fixed bug #748310 (pointer to function type mishandled when the
4990 function name is omitted). Also fixed a SIGSEGV when a function
4991 attribute (reentrant, etc) is used on a non-function or on a
4992 function but misplaced before the parameter list.
4994 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4996 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4997 * support/Util/SDCCerr.h,

5019 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5021 Made the constant following the "interrupt" keyword optional. If
5022 omitted, the function will not automatically be given an entry
5023 in the interrupt vector table (similar to #pragma NOIV, but
5024 less syntacticly kludgy). The interrupt number is also now
5025 range checked. Also fixed a bug in the high order bit example

5046 unsigned, but are signed by default
5047 * src/SDCCval.c (constVal): rearranged
5048 * src/SDCCval.c (valMod): preliminary fix
5049 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5091 constants are unsigned; added recognition of "u" flag for unsigned
5092 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5093 * src/SDCCval.c (valDiv, valMod): fixed signdness
5094 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

5555 added if/endif conditional macros to remove options help
5556 messages from optionsTable when a port is not configured, added
5557 support for the PIc16 port in the ports table, when executing
5558 the compiler with no port specified on command line, a default
5559 port is selected with the new macro DEFAULT_PORT which is
5560 defined in port.h, in setDefaultOptions() linkOptions is removed
5561 from initialization assignment, since now it is a set,
5562 parseCmdLine uses setParseWithComma for linkOptions, in
5563 linkEdit() linkOptions are accessed with new function indexSet()
5564 which returns the i'th item of a set variable. See SDCCset.c, in
5565 linkEdit() when calling buildCmdLine(), added linkOptions as
5566 last argument. Now users can pass arguments to gplink via the
5567 -Wl option, main() uses pic16glue() to glue up pic16 programs

5581 gpasm complaining and test the linkage with gplink, _linkCmd and
5582 _asmCmd changed to be more gplink and gpasm friendly
5583 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5584 produced an error when parsed, peep rule 12 is added to utilize
5585 movff, but it is commented out since the pCode does not support
5586 yet a command with 2 address arguments
5588 2003-05-18 <johan AT balder>
5590 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6608 2003-01-07 <johan AT balder>
6610 * src/SDCCast.c (decorateType): fixed bug #600035
6612 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6623 2003-01-06 <johan AT balder>
6625 * src/SDCCicode.c: fixed array add
6627 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6628 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6629 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6631 2003-01-04 <johan AT balder>
6633 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6635 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6636 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6638 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6639 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6645 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6646 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6648 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6649 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6651 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6653 * in \sdcc\as\mcs51\ changed these files in order to create an
6654 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6655 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6656 following files to include the previous two files: aslink.dsp,
6657 Makefile.aslink, Makefile.bcc, and Makefile.in.
6659 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6660 .adb instead of .cdb
6662 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6664 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6665 value from option --iram-size.
6667 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6669 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6672 2002-09-18 <wiml AT hhhh.org>
6674 * SDCClrange.h: exposed setFromRange() and setToRange()
6675 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6676 packRegsForAccUse() (bug 542397)
6677 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6678 multiple times and emitting the fetch operations more than once
6679 added aopGetUsesAcc() function to allow binary operators to
6680 fetch their operands in the correct order; made genMinus() emit
6681 compact code for X = LITERAL - Y
6683 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6684 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6685 sprintf() in line 1267.
6687 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6688 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6691 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6692 Changes to aslink (All the changes are marked with 'JCF'):
6694 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6697 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6698 area BSEG. Also moves, if possible, the DATA area down into the internal
6699 ram so more space is available.
6701 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6704 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6705 not bytes. Function summary() which creates a memory usage summary
6706 file with extension .mem. Reports of overlaping stack and small stack
6707 size. If the space for the stack is less than 16 bytes aslink trows a
6710 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6711 the 8051. Option 'y' for memory summary output file.
6713 Changes to sdcc (All the changes are marked with 'JCF'):
6715 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6717 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6718 overlaying area for it (uses RegBankUsed[4]).
6720 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6721 bank zero as used by default. By default aslink locates the stack
6722 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6723 the creation of the .mem file. Delegates the allocation of data area
6724 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6725 the begining of the stack area to aslink.
6727 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6728 glue() in SDCCglue.c creates an area for it.
6730 2002-09-03 Borut Razem <borut.razem AT siol.net>
6731 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6732 sdcc/src/pic/glue.c:
6733 introduced atexit() handler for teporay files removal in case of
6734 errors, assertions, ...
6736 2002-08-29 Borut Razem <borut.razem AT siol.net>
6737 * sdcc/support/cpp2/auto-host_vc_in.h:
6738 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6739 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6740 Maybe there is a similar problem with BORLANDC? It should be checked!
6742 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6743 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6744 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6745 was not executed, and the compiler (cl) launched a warning:
6746 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6748 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6749 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6751 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6752 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6754 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6755 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6756 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6757 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6758 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6759 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6760 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6761 - added Release configuration in VS projects
6762 - review of compiler an linker options
6763 - VC .exe files are generated in bin_vc directory, not to interfere
6764 with binaries generated from other projects (cygwin, mingw, bcc ...)
6766 * sdcc/src/yacc.dsp: added
6768 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6769 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6770 and insert the version number definitions from .version
6772 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6774 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6775 added - genarate auto-host.h using auto-host_vc_in.h as template
6778 removed from CVS, generated automatically
6780 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6781 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6783 2002-08-11 Borut Razem <borut.razem AT siol.net>
6784 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6786 2002-08-10 Borut Razem <borut.razem AT siol.net>
6787 * src/SDCCmain.c (main):
6788 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6789 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6790 The consequence was that some temporary files were not removed.
6793 unification of code in functions tempfilename() and tempfile():
6794 function tempnam() is defined in Visual Studio 6.0 and .NET
6796 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6798 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6799 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6800 - removed compiler command line option /WX: Treats all warnings as errors
6801 - update a list of source files, included into the project
6803 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6804 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6805 changed project type to Generic Project so that can be correcly converted to VS.NET project
6807 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6809 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6811 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6813 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6814 added return 0 statements after assert() to make compiler happy
6816 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6817 added newline in the def file to keep MSC compiler satisfied
6819 * sdcc/src/z80/gen.c:
6820 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6821 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6822 - solved MSC error in function aopDump()
6824 * sdcc_vc.h: define PREFIX as "\\sdcc"
6826 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6827 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6829 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6830 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6831 - Rewrote the register banking algorithm.
6832 - Added pCode live-range analysis to registers (for now, only non-used and
6833 singly-used registers optimized away)
6835 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6837 * 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.

6864 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6866 2002-03-28 Johan Knol <johan AT balder>
6868 * src/SDCCval.c: fixed bug #532436
6870 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6872 Added "char *Processor" field to the port structure.
6875 Added -p option. Allows port dependent processor to be specified.
6878 Initialized the new field char *Processor field to NULL in all ports
6881 Compiler generated registers for interrupt context saving
6882 were not getting allocated.
6884 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6887 Fixed left shift. Will promote the left side of a left shift
6888 if a) left shifting more than size of operand or b) when assigned
6889 to something size > size of left side
6891 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6893 tons of changes. Register allocation has been
6894 rewritten. Added customization for the various PICs. Flow

6901 Added. device.c is a PIC port hack to accomodate variations
6904 2002-03-13 Michael Hope <michaelh AT vroom>
6906 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6908 2002-03-04 johanknol <johanknol AT manik>
6910 * /src/SDCCval.c: fixed
6912 const unsigned char arr[][2] = { { 0, 1 } };
6913 t18.c:1: error: Initializer element is not constant
6915 2002-03-04 bela <bela AT manik>
6917 * /device/include/mcs51reg.h:
6918 ds89c420 register definition update

6999 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7001 * sdcc/src/SDCCloop.c:
7002 Previous fix was not good. basic blocks that have "break" or "return" are
7003 not really partof a loop , but live ranges used in these blocks should
7004 be live thru the entire loop, so set partOfLoop but don't add them to
7007 2002-02-21 <johan AT FRIJA>
7009 * src/SDCCcse.c: fixed bug #514308
7011 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7014 Fixed BUG #519583. If a conditional block ended in a return/break
7015 statement inside a loop, it was not being considered part of the loop.
7017 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7019 2002-02-10 Karl Bongers <karl AT turbobit.com>
7022 Fixed up SDCDB debugger somewhat. Updated debugger/README
7023 with lots of comments and notes.
7025 * device/examples/test2.c:
7026 Fix bug, "red" variable not being initialized(compiler complained).
