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

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

3399 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3400 loaded with the linker search paths (-L arguments) and the libraries
3401 to be linked with the current source (-l arguments). Changes
3402 currently will affect only the pic16 port.
3403 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3404 include path the port specific paths and port specific libraries,
3405 * gplink command now contains the $3 argument,
3406 * src/pic16/device.h,
3407 * src/pic16/device.c,: structure PIC_device is made public and
3408 renamed to PIC16_device, the same for variable Pics which is renamed

3423 Documenting changes from previous commits.
3424 * configure.in (version 1.56),
3425 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3426 when generating output files to configure the pic16 library,
3427 but now I've commented it out, since gputils aren't installed in the
3428 SF compile farm, so library won't compile
3430 * device/lib/Makefile.in (version 1.56): initially I've added in
3431 target 'all' the prerequestive 'model-pic16' so it compiled the
3432 pic16 library, but now I've commented it out for the same reasons
3434 * added targets 'model-pic16' and 'objects-pic16' to compile the
3436 * added target 'port-specific-objects-pic16' to handle the
3437 generated libraries and copy them into the build/ directory
3438 * added target 'clean-intermediate-pic16' to clean intermediate
3439 files into pic16 directory
3440 * in target 'installdirs' added line to create directory pic16 in

3462 option so that it actually works. Made it specific to the z80, since
3463 the gbz80 doesn't have these kinds of I/O ports.
3465 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3467 * device/include/z180.h,

3494 data are now emitted in sorted order to reduce section naming,
3495 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3496 weren't marked as being in the access bank,

3689 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3691 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3692 (default behaviour).
3694 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3696 A python script to validate compiler diagnostic messages. It can be
3697 used to verify that sdcc complains about bad c source code and
3698 gives a good location of the error.
3699 * support/valdiag/Makefile,
3700 * support/valdiag/valdiag.py,
3701 * support/valdiag/tests/*

3720 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3722 * sdcc.spec: updated
3723 * device/include/Makefile.in: don't install CVS directories
3724 * device/lib/Makefile.in: added removal of CVS directories after install
3725 * doc/Makefile: fixed install, added local_icons
3726 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3727 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3728 * src/ds390/gen.c (genRightShift): fixed bug #870788

3731 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3733 PIC16 port related changes:
3734 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3735 added variable stackPos,
3737 * gen.c: genCall, assignResultValue: added support for
3738 pushing/retrieving function parameters to/from stack,
3739 genFunction,genEndFunction: setup stack frame for the
3741 genAddrOf: will be changed according to bug 863624
3743 * added files genutils.c and genutils.h which contain gen*
3744 debugged and optimised functions extracted from gen.c
3746 * glue.c: added variable 'externs' which holds extern symbols,
3747 pic16emitRegularMap: is modified to properly handle relocatable
3748 symbols under the new scheme,
3749 pic16createInterruptVect: is modified
3750 pic16printPublics: is modified to emit 'global' assembler directives,
3751 added pic16_printExterns to print extern symbols,
3752 pic16glue: initializes stack/frame pointer in the beginning of
3753 the assembly output. Temporary hack, will be corrected later,
3754 because gplink yet does not support stack and SDCC does not
3755 yet support a type of crt0.o object to create the final binary.
3757 * Removed many lines that contain 8051 legacy code.
3758 * The code is finally placed under a 'code' directive.
3759 * Added port specific options.
3761 * _process_pragma: simplified since now we do not need *special*
3762 include file to define SFR registers. But a separate header
3763 will be needed. This will be developed later.
3764 * _pic16_parseOptions: added, parses port specific options:
3765 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3766 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3767 --preplace-udata-with=
3769 * _pic16_setDefaultOptions: modified to initialize section names,
3770 but hack is temporarly out of order since it needs improvement.
3771 * _pic16_genAssemblerPreamble: configuration words are emitted by
3772 their address instead of their name. This part is incomplete and
3773 supports only the 18Fxx2 devices. Other devices will emit an error
3774 during assembly since they do not contain the same set of config
3776 * _pic16_genIVT: is modified,
3778 * pcode.c: added definitions for some hardware registers that are needed
3780 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3781 All PCI entries are updated. Now LFSR is supported.
3782 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3783 * added pic16_newpCodeOpLit2 to support instructions with
3784 two literal arguments
3785 * pic16_pCode2str: corrected code that emits assembler instructions
3786 with two literal operands and those that have an access bit modifier
3787 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3788 this fixes a bug which caused some labels to be lost, when an
3789 assembler directive was added, i.e. banksel,
3790 * pic16_FixRegisterBanking: improved logic that causes the insertion
3792 * InlineFunction: functions that are called once, are not any more
3793 inlined. This can be a port option in the future,
3795 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3797 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3798 hold the corresponding uninitialized symbols,
3799 * pic16_allocProcessorRegister: registers have explicit marked the
3801 * pic16_allocInternalRegister: registers are explicit marked as
3803 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3804 processing list, so bit registers were lost,
3807 * ralloc.h: added field 'accessBank' and original symbol operand
3808 in register definition,
3809 * removed the field isMapped from register definition,
3811 ** Several functions have been removed from various sources:
3812 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3813 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3814 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3815 pic16_assignRelocatableRegisters
3817 ** others have been introduced:
3818 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3819 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3821 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3823 * support/scripts/inc2h.pl: changed definition of BIT_AT
3824 to emit 'sbit at' instead of 'bit at'. This was a request.
3826 PIC16 port related preliminary changes:
3827 * gen.c: prefixed function popRegFromString with
3828 pic16_ and all references to it corrected
3829 * pcode.c: all pic16_pc_* hardware registers prefixed
3830 with underscore (_),
3831 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3832 * ralloc.c: newReg(): when register is REG_SFR then
3833 set address to rIdx,
3834 pic16_allocProcessorRegister(): marks register wasUsed=0
3835 pic16_writeUsedRegs(): added a call to assign processor
3836 registers via pic16_assignFixedRegisters
3838 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3840 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3841 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3842 variables in unused register banks. Also the SSEG is placed
3843 wherever there is enough space for it, and IDATA can be anywhere
3844 in internal RAM. For now compile using -Wl-Y[stack_size].
3845 The mem file is different for this option as well, since it
3846 makes no sense of talking about DSEG lenght.
3848 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3850 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3851 in certain cases, e.g. when ROM assignment, patch provided
3852 from Albert den Haan.

4760 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4762 Fixed bug #621531 (const & volatile confusion in the type chain).
4763 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4857 fetching of the pointer
4858 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4859 copied from genNearPointerSet()
4860 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4861 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4862 If they pop r0/r1 they must be called in the opposite order than aopOp().
4863 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4864 (resp. --stack-auto), prepared for --xstack

4875 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4877 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4878 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4879 type for bits was changed. It resulted in bit variables becoming
4880 global, which is not permitted in PIC 14 assembly output.
4882 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4884 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4897 A few small changes that speed up the peephole optimizer.
4901 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4903 Try to make the peephole optimizer smarter by maintaining
4904 an association between the assembly source code and the
4905 iCodes that originated them. Put this information to use
4906 with a new peephole rule condition "notVolatile" so that
4907 the rules can be aggressive yet still safe.
4912 * src/mcs51/peeph.def
4914 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4918 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4919 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4920 if the left or right operand symbols have the accuse flag set.
4922 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4924 Changed the type of the result of the ! (NOT) operator to char;
4925 previously it returned the same type as the source. This allows
4926 us to eliminate all the genFloatNot functions (all of its target
4927 implementations were very buggy) since !float can use the same
4930 * src/SDCCicode.c (ast2iCode): ! returns char
4931 * src/mcs51/gen.c (genNot, genNotFloat),
4932 * src/ds390/gen.c (genNot, genNotFloat),
4933 * src/z80/gen.c (genNot, genNotFloat),
4934 * src/pic/gen.c (genNot, genNotFloat),
4935 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
4937 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4939 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4940 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4941 during interrupts. Ensure WSAVE is located at a shared bank address.
4942 2. Fixed page selection in some places
4943 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4944 the registers name strings.
4945 4. Fixed "signed / unsigned compare" compiler warnings.
4946 5. The PIC port manages its own allocation of the general purpose
4947 registers, but makes no attempt to reuse them. As a result when
4948 compiling it soon runs out of general purpose registers. Some
4949 additional code was added to the files pcode.c and device.c to walk
4950 through the function call tree and rename the registers so that they
4960 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4961 genPlus() & genMinus() when the result is the same as left or right
4963 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4967 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4969 Made bitfield a distinct type from bit so that bitfields
4970 convert as per ANSI C and bits retain their traditional
4971 boolean style behaviour. Implemented bitfield support in
4979 * src/ds390/gen.c: bit v bitfield split
4980 * src/z80/gen.c: New support for bitfields
4981 * support/regression/tests/bitfields.c: reenabled z80,
4984 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4986 Rules 246.x, 247.x relate to bitfields, the others speed up
4987 access to xdata mapped I/O devices.
4989 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4991 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4993 Cleaned up genPackBits and genUnpackBits and added two helper
4994 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4995 for literal assignments in genPackBits (thanks to Frieder for
5001 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5003 Fixed bug #748310 (pointer to function type mishandled when the
5004 function name is omitted). Also fixed a SIGSEGV when a function
5005 attribute (reentrant, etc) is used on a non-function or on a
5006 function but misplaced before the parameter list.
5008 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5010 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5011 * support/Util/SDCCerr.h,
5012 * support/Util/SDCCerr.c: Added func attr misuse error msg

5033 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5035 Made the constant following the "interrupt" keyword optional. If
5036 omitted, the function will not automatically be given an entry
5037 in the interrupt vector table (similar to #pragma NOIV, but
5038 less syntacticly kludgy). The interrupt number is also now
5039 range checked. Also fixed a bug in the high order bit example

5050 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5052 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5053 * src/SDCCicode.c (operandOperation): rewritten some ops
5054 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5055 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5057 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5058 be re-activated by defining REDUCE_LITERALS)
5059 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5060 unsigned, but are signed by default
5061 * src/SDCCval.c (constVal): rearranged
5062 * src/SDCCval.c (valMod): preliminary fix
5063 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5569 added if/endif conditional macros to remove options help
5570 messages from optionsTable when a port is not configured, added
5571 support for the PIc16 port in the ports table, when executing
5572 the compiler with no port specified on command line, a default
5573 port is selected with the new macro DEFAULT_PORT which is
5574 defined in port.h, in setDefaultOptions() linkOptions is removed
5575 from initialization assignment, since now it is a set,
5576 parseCmdLine uses setParseWithComma for linkOptions, in
5577 linkEdit() linkOptions are accessed with new function indexSet()
5578 which returns the i'th item of a set variable. See SDCCset.c, in
5579 linkEdit() when calling buildCmdLine(), added linkOptions as
5580 last argument. Now users can pass arguments to gplink via the
5581 -Wl option, main() uses pic16glue() to glue up pic16 programs

5595 gpasm complaining and test the linkage with gplink, _linkCmd and
5596 _asmCmd changed to be more gplink and gpasm friendly
5597 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5598 produced an error when parsed, peep rule 12 is added to utilize
5599 movff, but it is commented out since the pCode does not support
5600 yet a command with 2 address arguments
5602 2003-05-18 <johan AT balder>
5604 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5629 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5631 2003-05-11 Borut Razem <borut.razem AT siol.net>
5633 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6639 * src/SDCCicode.c: fixed array add
6641 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6642 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6643 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6645 2003-01-04 <johan AT balder>
6647 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6649 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6650 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6652 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

6662 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6663 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6665 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6667 * in \sdcc\as\mcs51\ changed these files in order to create an
6668 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6669 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6670 following files to include the previous two files: aslink.dsp,
6671 Makefile.aslink, Makefile.bcc, and Makefile.in.
6673 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6674 .adb instead of .cdb
6676 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6678 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6679 value from option --iram-size.
6681 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6683 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6686 2002-09-18 <wiml AT hhhh.org>
6688 * SDCClrange.h: exposed setFromRange() and setToRange()
6689 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6690 packRegsForAccUse() (bug 542397)
6691 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6692 multiple times and emitting the fetch operations more than once
6693 added aopGetUsesAcc() function to allow binary operators to
6694 fetch their operands in the correct order; made genMinus() emit
6695 compact code for X = LITERAL - Y
6697 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6698 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6699 sprintf() in line 1267.
6701 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6702 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6705 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6706 Changes to aslink (All the changes are marked with 'JCF'):
6708 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6711 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6712 area BSEG. Also moves, if possible, the DATA area down into the internal
6713 ram so more space is available.
6715 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6718 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6719 not bytes. Function summary() which creates a memory usage summary
6720 file with extension .mem. Reports of overlaping stack and small stack
6721 size. If the space for the stack is less than 16 bytes aslink trows a
6724 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6725 the 8051. Option 'y' for memory summary output file.
6727 Changes to sdcc (All the changes are marked with 'JCF'):
6729 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6731 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6732 overlaying area for it (uses RegBankUsed[4]).
6734 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6735 bank zero as used by default. By default aslink locates the stack
6736 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6737 the creation of the .mem file. Delegates the allocation of data area
6738 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6739 the begining of the stack area to aslink.
6741 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6742 glue() in SDCCglue.c creates an area for it.
6744 2002-09-03 Borut Razem <borut.razem AT siol.net>
6745 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6746 sdcc/src/pic/glue.c:
6747 introduced atexit() handler for teporay files removal in case of
6748 errors, assertions, ...
6750 2002-08-29 Borut Razem <borut.razem AT siol.net>
6751 * sdcc/support/cpp2/auto-host_vc_in.h:
6752 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6753 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6754 Maybe there is a similar problem with BORLANDC? It should be checked!
6756 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6757 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6758 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6759 was not executed, and the compiler (cl) launched a warning:
6760 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6762 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6763 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6765 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6766 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6768 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6769 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6770 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6771 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6772 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6773 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6774 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6775 - added Release configuration in VS projects
6776 - review of compiler an linker options
6777 - VC .exe files are generated in bin_vc directory, not to interfere
6778 with binaries generated from other projects (cygwin, mingw, bcc ...)
6780 * sdcc/src/yacc.dsp: added
6782 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6783 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6784 and insert the version number definitions from .version
6786 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6788 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6789 added - genarate auto-host.h using auto-host_vc_in.h as template
6792 removed from CVS, generated automatically
6794 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6795 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6797 2002-08-11 Borut Razem <borut.razem AT siol.net>
6798 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6800 2002-08-10 Borut Razem <borut.razem AT siol.net>
6801 * src/SDCCmain.c (main):
6802 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6803 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6804 The consequence was that some temporary files were not removed.
6807 unification of code in functions tempfilename() and tempfile():
6808 function tempnam() is defined in Visual Studio 6.0 and .NET
6810 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6812 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6813 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6814 - removed compiler command line option /WX: Treats all warnings as errors
6815 - update a list of source files, included into the project
6817 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6818 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6819 changed project type to Generic Project so that can be correcly converted to VS.NET project
6821 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6823 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6825 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6827 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6828 added return 0 statements after assert() to make compiler happy
6830 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6831 added newline in the def file to keep MSC compiler satisfied
6833 * sdcc/src/z80/gen.c:
6834 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6835 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6836 - solved MSC error in function aopDump()
6838 * sdcc_vc.h: define PREFIX as "\\sdcc"
6840 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6841 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6844 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6845 - Rewrote the register banking algorithm.
6846 - Added pCode live-range analysis to registers (for now, only non-used and
6847 singly-used registers optimized away)
6849 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6851 * 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.

6880 2002-03-28 Johan Knol <johan AT balder>
6882 * src/SDCCval.c: fixed bug #532436
6884 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6886 Added "char *Processor" field to the port structure.
6889 Added -p option. Allows port dependent processor to be specified.
6892 Initialized the new field char *Processor field to NULL in all ports
6895 Compiler generated registers for interrupt context saving
6896 were not getting allocated.
6898 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6901 Fixed left shift. Will promote the left side of a left shift
6902 if a) left shifting more than size of operand or b) when assigned
6903 to something size > size of left side
6905 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6907 tons of changes. Register allocation has been
6908 rewritten. Added customization for the various PICs. Flow
6909 analysis is restructured. ...
6915 Added. device.c is a PIC port hack to accomodate variations
6918 2002-03-13 Michael Hope <michaelh AT vroom>
6920 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7015 * sdcc/src/SDCCloop.c:
7016 Previous fix was not good. basic blocks that have "break" or "return" are
7017 not really partof a loop , but live ranges used in these blocks should
7018 be live thru the entire loop, so set partOfLoop but don't add them to
