1731 registers allocated in aopForSym for accessing stack symbols are not
1732 any more part of the functions usedRegs field,
1733 * (genCall): some times aopOp is called for a stack variable to be
1734 send, aopForSym might perform the push, if this is true make sure
1735 that genCall doesn't push the variable twice by testing _G.resDirect,
1736 * (genFunction): changed testing for unspecified interrupt number
1737 from 256 to INTNO_UNSPEC,
1738 * modified selection scheme of frame pointer generation. Previously
1739 if function did use local registers a frame pointer was generated,
1740 now a frame pointer is generated only if function has arguments
1741 (that need PLUSW2 register access), or has stack arguments, or the
1742 compiler is not instructed to omit the frame pointer,
1743 * (genEndFunction): before restoring local registers that were saved
1744 in the function preamble, also restore the registers that *might*
1745 have been allocated for stack access,
1746 * (genRet): removed some old comments,
1747 * (genCmp, the active (RN's) version): added a call to the
1748 pic16_genCmp_special function to perform the compare with a more
1749 robust and optimized way,
1750 * (genInline): a feature has been added in inline code generation,
1751 which allows a wildcard variable substitution when writing inline
1752 assembly. Code is incomplete and experimental therefore undocumented,
1753 * (genCast): changed order of aopOp for result and right to allow
1754 aopForSym to directly load the result if possible,
1755 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1756 perform an optimized compare on some selected special occasions,
1757 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1758 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1759 generate an IVT any more,
1760 * src/pic16/main.c (pic16_optionsTable): added command line option
1762 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1763 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1765 * src/pic16/NOTES: Raphael Neider added in list of active developers
1766 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1767 jumptable_end to prevent bug #,
1768 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1769 inCond and outCond fields,
1770 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1771 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1772 turn off register spilling,
1773 * (packRegsForOneUse): synced with other ports' versions although it
1774 is not used currently,
1775 * (pic16_packRegisters): added an optimization while reading
1776 structure bitfields, some registers may be saved (malloc code is
1777 decreased by 80 bytes)
1779 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1781 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1782 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1783 this can be optimized more?
1785 2005-03-10 Raphael Neider <rneider AT web.de>
1787 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1788 genNearPointerGet): (hopefully) fixed access to bitfields via
1789 pointers (p->bitN = x; and x = p->bitN; failed)

2115 access stack and frame pointers. They are initially assigned to
2116 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2117 accessing SFRs. Updated all occurences of modification of stack or
2118 frame pointer in gen.c and pcode.c,
2119 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
2120 assigning of a literal value to pointers,

2163 from Raphael Neider,
2164 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
2165 for 8-bit literals. This fixes some literal operands which are sign
2166 extended to 16-bits ints when instruction needs only 8-bits.

2423 Adding support for replacing ljmps with sjmps in jumptables
2424 generated for switch statements. For now you need to set the
2425 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2426 Now 4 algorithms for mcs51 jumptable generation are used:
2427 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2428 addresses loaded pc-relative for up to 112 cases and stack-pushing
2429 target addresses loaded with offset from dptr for up to 256 cases.

2461 * added libc directory. The current version of LibC contains string
2462 functions, ctype functions and macros and some functions of the
2463 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2464 be extensively tested in the future. Standard disclaimer here.

2477 * (pic16_storeForReturn): optimized return of 0,
2478 * (genCmp): experimental code for new genCmp which uses PIC18's
2479 special compare&skip instructions. Initial tests fail some times
2480 with variables grater than 1 byte in size, so new code is disabled,
2481 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2483 * (genCast): began a fix to optimize the casting of a bit to another
2484 bit, now assigning a bitfield to another bitfield will fail, sorry,

2493 and 1 for banking instruction,
2494 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2495 caused stop processing pCodes after a inline assembly block,
2496 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2498 registers when it shouldn't,
2499 * src/pic16/ralloc.c (allocReg): add preliminary support for
2500 supporting a limited set of temporary registers,
2502 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5509 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5510 loaded with the linker search paths (-L arguments) and the libraries
5511 to be linked with the current source (-l arguments). Changes
5512 currently will affect only the pic16 port.
5513 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5514 include path the port specific paths and port specific libraries,
5515 * gplink command now contains the $3 argument,
5516 * src/pic16/device.h,
5517 * src/pic16/device.c,: structure PIC_device is made public and
5518 renamed to PIC16_device, the same for variable Pics which is renamed

5533 Documenting changes from previous commits.
5534 * configure.in (version 1.56),
5535 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5536 when generating output files to configure the pic16 library,
5537 but now I've commented it out, since gputils aren't installed in the
5538 SF compile farm, so library won't compile
5540 * device/lib/Makefile.in (version 1.56): initially I've added in
5541 target 'all' the prerequestive 'model-pic16' so it compiled the
5542 pic16 library, but now I've commented it out for the same reasons
5544 * added targets 'model-pic16' and 'objects-pic16' to compile the
5546 * added target 'port-specific-objects-pic16' to handle the
5547 generated libraries and copy them into the build/ directory
5548 * added target 'clean-intermediate-pic16' to clean intermediate
5549 files into pic16 directory
5550 * in target 'installdirs' added line to create directory pic16 in

5572 option so that it actually works. Made it specific to the z80, since
5573 the gbz80 doesn't have these kinds of I/O ports.
5575 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5577 * device/include/z180.h,

5604 data are now emitted in sorted order to reduce section naming,
5605 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5606 weren't marked as being in the access bank,

5799 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5801 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5802 (default behaviour).
5804 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5806 A python script to validate compiler diagnostic messages. It can be
5807 used to verify that sdcc complains about bad c source code and
5808 gives a good location of the error.
5809 * support/valdiag/Makefile,
5810 * support/valdiag/valdiag.py,
5811 * support/valdiag/tests/*

5830 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5832 * sdcc.spec: updated
5833 * device/include/Makefile.in: don't install CVS directories

5835 * doc/Makefile: fixed install, added local_icons
5836 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5837 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5838 * src/ds390/gen.c (genRightShift): fixed bug #870788

5841 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5843 PIC16 port related changes:
5844 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5845 added variable stackPos,
5847 * gen.c: genCall, assignResultValue: added support for
5848 pushing/retrieving function parameters to/from stack,
5849 genFunction,genEndFunction: setup stack frame for the
5851 genAddrOf: will be changed according to bug 863624
5853 * added files genutils.c and genutils.h which contain gen*
5854 debugged and optimised functions extracted from gen.c
5856 * glue.c: added variable 'externs' which holds extern symbols,
5857 pic16emitRegularMap: is modified to properly handle relocatable
5858 symbols under the new scheme,
5859 pic16createInterruptVect: is modified
5860 pic16printPublics: is modified to emit 'global' assembler directives,
5861 added pic16_printExterns to print extern symbols,
5862 pic16glue: initializes stack/frame pointer in the beginning of
5863 the assembly output. Temporary hack, will be corrected later,
5864 because gplink yet does not support stack and SDCC does not
5865 yet support a type of crt0.o object to create the final binary.
5867 * Removed many lines that contain 8051 legacy code.
5868 * The code is finally placed under a 'code' directive.
5869 * Added port specific options.
5871 * _process_pragma: simplified since now we do not need *special*
5872 include file to define SFR registers. But a separate header
5873 will be needed. This will be developed later.
5874 * _pic16_parseOptions: added, parses port specific options:
5875 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5876 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5877 --preplace-udata-with=
5879 * _pic16_setDefaultOptions: modified to initialize section names,
5880 but hack is temporarly out of order since it needs improvement.
5881 * _pic16_genAssemblerPreamble: configuration words are emitted by
5882 their address instead of their name. This part is incomplete and
5883 supports only the 18Fxx2 devices. Other devices will emit an error
5884 during assembly since they do not contain the same set of config
5886 * _pic16_genIVT: is modified,
5888 * pcode.c: added definitions for some hardware registers that are needed
5890 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5891 All PCI entries are updated. Now LFSR is supported.
5892 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5893 * added pic16_newpCodeOpLit2 to support instructions with
5894 two literal arguments
5895 * pic16_pCode2str: corrected code that emits assembler instructions
5896 with two literal operands and those that have an access bit modifier
5897 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5898 this fixes a bug which caused some labels to be lost, when an
5899 assembler directive was added, i.e. banksel,
5900 * pic16_FixRegisterBanking: improved logic that causes the insertion
5902 * InlineFunction: functions that are called once, are not any more
5903 inlined. This can be a port option in the future,
5905 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5907 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5908 hold the corresponding uninitialized symbols,
5909 * pic16_allocProcessorRegister: registers have explicit marked the
5911 * pic16_allocInternalRegister: registers are explicit marked as
5913 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5914 processing list, so bit registers were lost,
5917 * ralloc.h: added field 'accessBank' and original symbol operand
5918 in register definition,
5919 * removed the field isMapped from register definition,
5921 ** Several functions have been removed from various sources:
5922 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5923 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5924 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5925 pic16_assignRelocatableRegisters
5927 ** others have been introduced:
5928 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5929 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5931 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5933 * support/scripts/inc2h.pl: changed definition of BIT_AT
5934 to emit 'sbit at' instead of 'bit at'. This was a request.
5936 PIC16 port related preliminary changes:
5937 * gen.c: prefixed function popRegFromString with
5938 pic16_ and all references to it corrected
5939 * pcode.c: all pic16_pc_* hardware registers prefixed
5940 with underscore (_),
5941 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5942 * ralloc.c: newReg(): when register is REG_SFR then
5943 set address to rIdx,
5944 pic16_allocProcessorRegister(): marks register wasUsed=0
5945 pic16_writeUsedRegs(): added a call to assign processor
5946 registers via pic16_assignFixedRegisters
5948 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5950 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5951 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5952 variables in unused register banks. Also the SSEG is placed
5953 wherever there is enough space for it, and IDATA can be anywhere
5954 in internal RAM. For now compile using -Wl-Y[stack_size].
5955 The mem file is different for this option as well, since it
5956 makes no sense of talking about DSEG lenght.
5958 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5960 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5961 in certain cases, e.g. when ROM assignment, patch provided
5962 from Albert den Haan.

6966 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6967 fetching of the pointer
6968 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6969 copied from genNearPointerSet()
6970 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6971 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6987 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6988 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6989 type for bits was changed. It resulted in bit variables becoming

7007 A few small changes that speed up the peephole optimizer.
7011 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7013 Try to make the peephole optimizer smarter by maintaining
7014 an association between the assembly source code and the
7015 iCodes that originated them. Put this information to use
7016 with a new peephole rule condition "notVolatile" so that
7017 the rules can be aggressive yet still safe.
7022 * src/mcs51/peeph.def
7024 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7028 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7029 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7030 if the left or right operand symbols have the accuse flag set.
7032 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7034 Changed the type of the result of the ! (NOT) operator to char;
7035 previously it returned the same type as the source. This allows
7036 us to eliminate all the genFloatNot functions (all of its target
7037 implementations were very buggy) since !float can use the same

7049 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7050 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7051 during interrupts. Ensure WSAVE is located at a shared bank address.
7052 2. Fixed page selection in some places
7053 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7054 the registers name strings.
7055 4. Fixed "signed / unsigned compare" compiler warnings.
7056 5. The PIC port manages its own allocation of the general purpose
7057 registers, but makes no attempt to reuse them. As a result when
7058 compiling it soon runs out of general purpose registers. Some
7059 additional code was added to the files pcode.c and device.c to walk
7060 through the function call tree and rename the registers so that they
7070 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7077 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7079 Made bitfield a distinct type from bit so that bitfields
7080 convert as per ANSI C and bits retain their traditional
7081 boolean style behaviour. Implemented bitfield support in
7089 * src/ds390/gen.c: bit v bitfield split
7090 * src/z80/gen.c: New support for bitfields

7094 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7096 Rules 246.x, 247.x relate to bitfields, the others speed up
7097 access to xdata mapped I/O devices.
7099 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7101 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7103 Cleaned up genPackBits and genUnpackBits and added two helper

7113 Fixed bug #748310 (pointer to function type mishandled when the
7114 function name is omitted). Also fixed a SIGSEGV when a function
7115 attribute (reentrant, etc) is used on a non-function or on a
7116 function but misplaced before the parameter list.

7145 Made the constant following the "interrupt" keyword optional. If
7146 omitted, the function will not automatically be given an entry
7147 in the interrupt vector table (similar to #pragma NOIV, but
7148 less syntacticly kludgy). The interrupt number is also now
7149 range checked. Also fixed a bug in the high order bit example

7680 messages from optionsTable when a port is not configured, added
7681 support for the PIc16 port in the ports table, when executing
7682 the compiler with no port specified on command line, a default
7683 port is selected with the new macro DEFAULT_PORT which is
7684 defined in port.h, in setDefaultOptions() linkOptions is removed
7685 from initialization assignment, since now it is a set,
7686 parseCmdLine uses setParseWithComma for linkOptions, in
7687 linkEdit() linkOptions are accessed with new function indexSet()
7688 which returns the i'th item of a set variable. See SDCCset.c, in
7689 linkEdit() when calling buildCmdLine(), added linkOptions as
7690 last argument. Now users can pass arguments to gplink via the
7691 -Wl option, main() uses pic16glue() to glue up pic16 programs

7705 gpasm complaining and test the linkage with gplink, _linkCmd and
7706 _asmCmd changed to be more gplink and gpasm friendly
7707 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7708 produced an error when parsed, peep rule 12 is added to utilize
7709 movff, but it is commented out since the pCode does not support
7710 yet a command with 2 address arguments
7712 2003-05-18 <johan AT balder>
7714 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8747 2003-01-06 <johan AT balder>
8749 * src/SDCCicode.c: fixed array add
8751 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8752 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8753 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8755 2003-01-04 <johan AT balder>
8757 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8759 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8760 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8762 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8763 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8772 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8773 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8775 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8777 * in \sdcc\as\mcs51\ changed these files in order to create an
8778 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8779 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8780 following files to include the previous two files: aslink.dsp,
8781 Makefile.aslink, Makefile.bcc, and Makefile.in.
8783 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8784 .adb instead of .cdb
8786 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8788 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8789 value from option --iram-size.
8791 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8793 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8796 2002-09-18 <wiml AT hhhh.org>
8798 * SDCClrange.h: exposed setFromRange() and setToRange()
8799 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8800 packRegsForAccUse() (bug 542397)
8801 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8802 multiple times and emitting the fetch operations more than once
8803 added aopGetUsesAcc() function to allow binary operators to
8804 fetch their operands in the correct order; made genMinus() emit
8805 compact code for X = LITERAL - Y
8807 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8808 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8809 sprintf() in line 1267.
8811 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8812 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8815 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8816 Changes to aslink (All the changes are marked with 'JCF'):
8818 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8821 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8822 area BSEG. Also moves, if possible, the DATA area down into the internal
8823 ram so more space is available.
8825 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8828 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8829 not bytes. Function summary() which creates a memory usage summary
8830 file with extension .mem. Reports of overlaping stack and small stack
8831 size. If the space for the stack is less than 16 bytes aslink trows a
8834 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8835 the 8051. Option 'y' for memory summary output file.
8837 Changes to sdcc (All the changes are marked with 'JCF'):
8839 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8841 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8842 overlaying area for it (uses RegBankUsed[4]).
8844 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8845 bank zero as used by default. By default aslink locates the stack
8846 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8847 the creation of the .mem file. Delegates the allocation of data area
8848 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8849 the begining of the stack area to aslink.
8851 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8852 glue() in SDCCglue.c creates an area for it.
8854 2002-09-03 Borut Razem <borut.razem AT siol.net>
8855 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8856 sdcc/src/pic/glue.c:
8857 introduced atexit() handler for teporay files removal in case of
8858 errors, assertions, ...
8860 2002-08-29 Borut Razem <borut.razem AT siol.net>
8861 * sdcc/support/cpp2/auto-host_vc_in.h:
8862 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8863 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8864 Maybe there is a similar problem with BORLANDC? It should be checked!
8866 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8867 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8868 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8869 was not executed, and the compiler (cl) launched a warning:
8870 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8872 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8873 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8875 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8876 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8878 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8879 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8880 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8881 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8882 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8883 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8884 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8885 - added Release configuration in VS projects
8886 - review of compiler an linker options
8887 - VC .exe files are generated in bin_vc directory, not to interfere
8888 with binaries generated from other projects (cygwin, mingw, bcc ...)
8890 * sdcc/src/yacc.dsp: added
8892 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8893 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8894 and insert the version number definitions from .version
8896 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8898 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8899 added - genarate auto-host.h using auto-host_vc_in.h as template
8902 removed from CVS, generated automatically
8904 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8905 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8907 2002-08-11 Borut Razem <borut.razem AT siol.net>
8908 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8910 2002-08-10 Borut Razem <borut.razem AT siol.net>
8911 * src/SDCCmain.c (main):
8912 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8913 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8914 The consequence was that some temporary files were not removed.
8917 unification of code in functions tempfilename() and tempfile():
8918 function tempnam() is defined in Visual Studio 6.0 and .NET
8920 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8922 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8923 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8924 - removed compiler command line option /WX: Treats all warnings as errors
8925 - update a list of source files, included into the project
8927 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8928 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8929 changed project type to Generic Project so that can be correcly converted to VS.NET project
8931 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8933 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8935 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8937 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8938 added return 0 statements after assert() to make compiler happy
8940 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8941 added newline in the def file to keep MSC compiler satisfied
8943 * sdcc/src/z80/gen.c:
8944 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8945 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8946 - solved MSC error in function aopDump()
8948 * sdcc_vc.h: define PREFIX as "\\sdcc"
8950 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8951 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8953 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8954 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8955 - Rewrote the register banking algorithm.
8956 - Added pCode live-range analysis to registers (for now, only non-used and
8957 singly-used registers optimized away)
8959 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8961 * 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.
8963 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8964 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8966 2002-04-22 Michael Hope <michaelh AT vroom>

8986 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8988 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8990 2002-03-28 Johan Knol <johan AT balder>
8992 * src/SDCCval.c: fixed bug #532436
8994 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8996 Added "char *Processor" field to the port structure.
8999 Added -p option. Allows port dependent processor to be specified.
9002 Initialized the new field char *Processor field to NULL in all ports
9005 Compiler generated registers for interrupt context saving
9006 were not getting allocated.
9008 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9011 Fixed left shift. Will promote the left side of a left shift
9012 if a) left shifting more than size of operand or b) when assigned
9013 to something size > size of left side
9015 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9017 tons of changes. Register allocation has been
9018 rewritten. Added customization for the various PICs. Flow
9019 analysis is restructured. ...
9025 Added. device.c is a PIC port hack to accomodate variations
9028 2002-03-13 Michael Hope <michaelh AT vroom>
9030 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9032 2002-03-04 johanknol <johanknol AT manik>
9034 * /src/SDCCval.c: fixed
9036 const unsigned char arr[][2] = { { 0, 1 } };
9037 t18.c:1: error: Initializer element is not constant
9039 2002-03-04 bela <bela AT manik>
9041 * /device/include/mcs51reg.h:
9042 ds89c420 register definition update
9044 2002-03-03 <johan AT FRIJA>

9123 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9125 * sdcc/src/SDCCloop.c:
9126 Previous fix was not good. basic blocks that have "break" or "return" are
9127 not really partof a loop , but live ranges used in these blocks should
9128 be live thru the entire loop, so set partOfLoop but don't add them to
9131 2002-02-21 <johan AT FRIJA>
9133 * src/SDCCcse.c: fixed bug #514308
9135 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9138 Fixed BUG #519583. If a conditional block ended in a return/break
9139 statement inside a loop, it was not being considered part of the loop.
9141 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9143 2002-02-10 Karl Bongers <karl AT turbobit.com>
