1733 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1734 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1735 optimizations. Currently only compare to unsigned char is implemented,
1736 * src/pic16/gen.c: added fReturnIdx array,
1737 * (struct resolvedIfx) is moved to gen.h and made public,
1738 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1739 * (aopForSym): added an optimization to directly store in stack of
1740 the operand of a SEND iCode,
1741 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1742 but as registers instead (AOP_REG) using the fReturnIdx array,
1743 * (pic16_freeAsmop): remove the freed register from the
1744 _G.sregsAlloc field,
1745 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1746 a compare of 'WREG',
1747 * (pic16_popGetTempRegCond): changed function prototype, now
1748 function takes also a bitVector argument v which holds the current
1749 set of registers that are allocated for stack access by aopForSym,
1750 registers allocated in aopForSym for accessing stack symbols are not
1751 any more part of the functions usedRegs field,
1752 * (genCall): some times aopOp is called for a stack variable to be
1753 send, aopForSym might perform the push, if this is true make sure
1754 that genCall doesn't push the variable twice by testing _G.resDirect,
1755 * (genFunction): changed testing for unspecified interrupt number
1756 from 256 to INTNO_UNSPEC,
1757 * modified selection scheme of frame pointer generation. Previously
1758 if function did use local registers a frame pointer was generated,
1759 now a frame pointer is generated only if function has arguments
1760 (that need PLUSW2 register access), or has stack arguments, or the
1761 compiler is not instructed to omit the frame pointer,
1762 * (genEndFunction): before restoring local registers that were saved
1763 in the function preamble, also restore the registers that *might*
1764 have been allocated for stack access,
1765 * (genRet): removed some old comments,
1766 * (genCmp, the active (RN's) version): added a call to the
1767 pic16_genCmp_special function to perform the compare with a more
1768 robust and optimized way,
1769 * (genInline): a feature has been added in inline code generation,
1770 which allows a wildcard variable substitution when writing inline
1771 assembly. Code is incomplete and experimental therefore undocumented,
1772 * (genCast): changed order of aopOp for result and right to allow
1773 aopForSym to directly load the result if possible,
1774 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1775 perform an optimized compare on some selected special occasions,
1776 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1777 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1778 generate an IVT any more,
1779 * src/pic16/main.c (pic16_optionsTable): added command line option
1781 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1782 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1784 * src/pic16/NOTES: Raphael Neider added in list of active developers
1785 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1786 jumptable_end to prevent bug #,
1787 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1788 inCond and outCond fields,
1789 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1790 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1791 turn off register spilling,
1792 * (packRegsForOneUse): synced with other ports' versions although it
1793 is not used currently,
1794 * (pic16_packRegisters): added an optimization while reading
1795 structure bitfields, some registers may be saved (malloc code is
1796 decreased by 80 bytes)
1798 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1800 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1801 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1802 this can be optimized more?
1804 2005-03-10 Raphael Neider <rneider AT web.de>
1806 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1807 genNearPointerGet): (hopefully) fixed access to bitfields via
1808 pointers (p->bitN = x; and x = p->bitN; failed)

2134 access stack and frame pointers. They are initially assigned to
2135 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2136 accessing SFRs. Updated all occurences of modification of stack or
2137 frame pointer in gen.c and pcode.c,

2442 Adding support for replacing ljmps with sjmps in jumptables
2443 generated for switch statements. For now you need to set the
2444 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2445 Now 4 algorithms for mcs51 jumptable generation are used:
2446 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2447 addresses loaded pc-relative for up to 112 cases and stack-pushing
2448 target addresses loaded with offset from dptr for up to 256 cases.

2480 * added libc directory. The current version of LibC contains string
2481 functions, ctype functions and macros and some functions of the
2482 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2483 be extensively tested in the future. Standard disclaimer here.

2496 * (pic16_storeForReturn): optimized return of 0,
2497 * (genCmp): experimental code for new genCmp which uses PIC18's
2498 special compare&skip instructions. Initial tests fail some times
2499 with variables grater than 1 byte in size, so new code is disabled,
2500 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2502 * (genCast): began a fix to optimize the casting of a bit to another
2503 bit, now assigning a bitfield to another bitfield will fail, sorry,

2517 registers when it shouldn't,
2518 * src/pic16/ralloc.c (allocReg): add preliminary support for
2519 supporting a limited set of temporary registers,
2521 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5529 loaded with the linker search paths (-L arguments) and the libraries
5530 to be linked with the current source (-l arguments). Changes
5531 currently will affect only the pic16 port.
5532 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5533 include path the port specific paths and port specific libraries,
5534 * gplink command now contains the $3 argument,
5535 * src/pic16/device.h,
5536 * src/pic16/device.c,: structure PIC_device is made public and
5537 renamed to PIC16_device, the same for variable Pics which is renamed

5552 Documenting changes from previous commits.
5553 * configure.in (version 1.56),
5554 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5555 when generating output files to configure the pic16 library,
5556 but now I've commented it out, since gputils aren't installed in the
5557 SF compile farm, so library won't compile
5559 * device/lib/Makefile.in (version 1.56): initially I've added in
5560 target 'all' the prerequestive 'model-pic16' so it compiled the
5561 pic16 library, but now I've commented it out for the same reasons
5563 * added targets 'model-pic16' and 'objects-pic16' to compile the
5565 * added target 'port-specific-objects-pic16' to handle the
5566 generated libraries and copy them into the build/ directory
5567 * added target 'clean-intermediate-pic16' to clean intermediate
5568 files into pic16 directory
5569 * in target 'installdirs' added line to create directory pic16 in

5591 option so that it actually works. Made it specific to the z80, since
5592 the gbz80 doesn't have these kinds of I/O ports.
5594 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5818 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5820 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5821 (default behaviour).
5823 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5825 A python script to validate compiler diagnostic messages. It can be
5826 used to verify that sdcc complains about bad c source code and
5827 gives a good location of the error.
5828 * support/valdiag/Makefile,
5829 * support/valdiag/valdiag.py,
5830 * support/valdiag/tests/*

5849 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5851 * sdcc.spec: updated
5852 * device/include/Makefile.in: don't install CVS directories
5853 * device/lib/Makefile.in: added removal of CVS directories after install
5854 * doc/Makefile: fixed install, added local_icons
5855 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5856 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5857 * src/ds390/gen.c (genRightShift): fixed bug #870788
5858 * src/SDCCast.c (decorateType): fixed bug #870781
5860 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5862 PIC16 port related changes:
5863 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5864 added variable stackPos,
5866 * gen.c: genCall, assignResultValue: added support for
5867 pushing/retrieving function parameters to/from stack,
5868 genFunction,genEndFunction: setup stack frame for the
5870 genAddrOf: will be changed according to bug 863624
5872 * added files genutils.c and genutils.h which contain gen*
5873 debugged and optimised functions extracted from gen.c
5875 * glue.c: added variable 'externs' which holds extern symbols,
5876 pic16emitRegularMap: is modified to properly handle relocatable
5877 symbols under the new scheme,
5878 pic16createInterruptVect: is modified
5879 pic16printPublics: is modified to emit 'global' assembler directives,
5880 added pic16_printExterns to print extern symbols,
5881 pic16glue: initializes stack/frame pointer in the beginning of
5882 the assembly output. Temporary hack, will be corrected later,
5883 because gplink yet does not support stack and SDCC does not
5884 yet support a type of crt0.o object to create the final binary.
5886 * Removed many lines that contain 8051 legacy code.
5887 * The code is finally placed under a 'code' directive.
5888 * Added port specific options.
5890 * _process_pragma: simplified since now we do not need *special*
5891 include file to define SFR registers. But a separate header
5892 will be needed. This will be developed later.
5893 * _pic16_parseOptions: added, parses port specific options:
5894 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5895 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5896 --preplace-udata-with=
5898 * _pic16_setDefaultOptions: modified to initialize section names,
5899 but hack is temporarly out of order since it needs improvement.
5900 * _pic16_genAssemblerPreamble: configuration words are emitted by
5901 their address instead of their name. This part is incomplete and
5902 supports only the 18Fxx2 devices. Other devices will emit an error
5903 during assembly since they do not contain the same set of config
5905 * _pic16_genIVT: is modified,
5907 * pcode.c: added definitions for some hardware registers that are needed
5909 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5910 All PCI entries are updated. Now LFSR is supported.
5911 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5912 * added pic16_newpCodeOpLit2 to support instructions with
5913 two literal arguments
5914 * pic16_pCode2str: corrected code that emits assembler instructions
5915 with two literal operands and those that have an access bit modifier
5916 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5917 this fixes a bug which caused some labels to be lost, when an
5918 assembler directive was added, i.e. banksel,
5919 * pic16_FixRegisterBanking: improved logic that causes the insertion
5921 * InlineFunction: functions that are called once, are not any more
5922 inlined. This can be a port option in the future,
5924 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5926 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5927 hold the corresponding uninitialized symbols,
5928 * pic16_allocProcessorRegister: registers have explicit marked the
5930 * pic16_allocInternalRegister: registers are explicit marked as
5932 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5933 processing list, so bit registers were lost,
5936 * ralloc.h: added field 'accessBank' and original symbol operand
5937 in register definition,
5938 * removed the field isMapped from register definition,
5940 ** Several functions have been removed from various sources:
5941 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5942 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5943 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5944 pic16_assignRelocatableRegisters
5946 ** others have been introduced:
5947 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5948 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5950 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5952 * support/scripts/inc2h.pl: changed definition of BIT_AT
5953 to emit 'sbit at' instead of 'bit at'. This was a request.
5955 PIC16 port related preliminary changes:
5956 * gen.c: prefixed function popRegFromString with
5957 pic16_ and all references to it corrected
5958 * pcode.c: all pic16_pc_* hardware registers prefixed
5959 with underscore (_),
5960 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5961 * ralloc.c: newReg(): when register is REG_SFR then
5962 set address to rIdx,
5963 pic16_allocProcessorRegister(): marks register wasUsed=0
5964 pic16_writeUsedRegs(): added a call to assign processor
5965 registers via pic16_assignFixedRegisters
5967 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5969 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5970 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5971 variables in unused register banks. Also the SSEG is placed
5972 wherever there is enough space for it, and IDATA can be anywhere
5973 in internal RAM. For now compile using -Wl-Y[stack_size].
5974 The mem file is different for this option as well, since it
5975 makes no sense of talking about DSEG lenght.
5977 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5979 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5980 in certain cases, e.g. when ROM assignment, patch provided
5981 from Albert den Haan.
5983 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6985 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6986 fetching of the pointer
6987 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6988 copied from genNearPointerSet()
6989 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6990 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7006 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7007 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7008 type for bits was changed. It resulted in bit variables becoming
7009 global, which is not permitted in PIC 14 assembly output.
7011 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7026 A few small changes that speed up the peephole optimizer.
7030 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7032 Try to make the peephole optimizer smarter by maintaining
7033 an association between the assembly source code and the
7034 iCodes that originated them. Put this information to use
7035 with a new peephole rule condition "notVolatile" so that
7036 the rules can be aggressive yet still safe.
7041 * src/mcs51/peeph.def
7043 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7047 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7048 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7049 if the left or right operand symbols have the accuse flag set.
7051 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7053 Changed the type of the result of the ! (NOT) operator to char;
7054 previously it returned the same type as the source. This allows
7055 us to eliminate all the genFloatNot functions (all of its target
7056 implementations were very buggy) since !float can use the same
7059 * src/SDCCicode.c (ast2iCode): ! returns char

7068 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7069 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7070 during interrupts. Ensure WSAVE is located at a shared bank address.
7071 2. Fixed page selection in some places
7072 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7073 the registers name strings.
7074 4. Fixed "signed / unsigned compare" compiler warnings.
7075 5. The PIC port manages its own allocation of the general purpose
7076 registers, but makes no attempt to reuse them. As a result when
7077 compiling it soon runs out of general purpose registers. Some
7078 additional code was added to the files pcode.c and device.c to walk
7079 through the function call tree and rename the registers so that they
7089 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7096 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7098 Made bitfield a distinct type from bit so that bitfields
7099 convert as per ANSI C and bits retain their traditional
7100 boolean style behaviour. Implemented bitfield support in
7108 * src/ds390/gen.c: bit v bitfield split
7109 * src/z80/gen.c: New support for bitfields
7110 * support/regression/tests/bitfields.c: reenabled z80,
7113 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7115 Rules 246.x, 247.x relate to bitfields, the others speed up
7116 access to xdata mapped I/O devices.
7118 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7120 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7122 Cleaned up genPackBits and genUnpackBits and added two helper
7123 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7124 for literal assignments in genPackBits (thanks to Frieder for
7130 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7132 Fixed bug #748310 (pointer to function type mishandled when the
7133 function name is omitted). Also fixed a SIGSEGV when a function
7134 attribute (reentrant, etc) is used on a non-function or on a
7135 function but misplaced before the parameter list.
7137 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7139 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7140 * support/Util/SDCCerr.h,

7162 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7164 Made the constant following the "interrupt" keyword optional. If
7165 omitted, the function will not automatically be given an entry
7166 in the interrupt vector table (similar to #pragma NOIV, but
7167 less syntacticly kludgy). The interrupt number is also now
7168 range checked. Also fixed a bug in the high order bit example

7698 added if/endif conditional macros to remove options help
7699 messages from optionsTable when a port is not configured, added
7700 support for the PIc16 port in the ports table, when executing
7701 the compiler with no port specified on command line, a default
7702 port is selected with the new macro DEFAULT_PORT which is
7703 defined in port.h, in setDefaultOptions() linkOptions is removed
7704 from initialization assignment, since now it is a set,
7705 parseCmdLine uses setParseWithComma for linkOptions, in
7706 linkEdit() linkOptions are accessed with new function indexSet()
7707 which returns the i'th item of a set variable. See SDCCset.c, in
7708 linkEdit() when calling buildCmdLine(), added linkOptions as
7709 last argument. Now users can pass arguments to gplink via the
7710 -Wl option, main() uses pic16glue() to glue up pic16 programs

7724 gpasm complaining and test the linkage with gplink, _linkCmd and
7725 _asmCmd changed to be more gplink and gpasm friendly
7726 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7727 produced an error when parsed, peep rule 12 is added to utilize
7728 movff, but it is commented out since the pCode does not support
7729 yet a command with 2 address arguments
7731 2003-05-18 <johan AT balder>
7733 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7758 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7760 2003-05-11 Borut Razem <borut.razem AT siol.net>
7762 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8768 * src/SDCCicode.c: fixed array add
8770 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8771 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8772 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8774 2003-01-04 <johan AT balder>
8776 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8778 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8779 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8781 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8791 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8792 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8794 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8796 * in \sdcc\as\mcs51\ changed these files in order to create an
8797 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8798 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8799 following files to include the previous two files: aslink.dsp,
8800 Makefile.aslink, Makefile.bcc, and Makefile.in.
8802 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8803 .adb instead of .cdb
8805 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8807 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8808 value from option --iram-size.
8810 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8812 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8815 2002-09-18 <wiml AT hhhh.org>
8817 * SDCClrange.h: exposed setFromRange() and setToRange()
8818 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8819 packRegsForAccUse() (bug 542397)
8820 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8821 multiple times and emitting the fetch operations more than once
8822 added aopGetUsesAcc() function to allow binary operators to
8823 fetch their operands in the correct order; made genMinus() emit
8824 compact code for X = LITERAL - Y
8826 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8827 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8828 sprintf() in line 1267.
8830 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8831 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8834 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8835 Changes to aslink (All the changes are marked with 'JCF'):
8837 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8840 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8841 area BSEG. Also moves, if possible, the DATA area down into the internal
8842 ram so more space is available.
8844 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8847 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8848 not bytes. Function summary() which creates a memory usage summary
8849 file with extension .mem. Reports of overlaping stack and small stack
8850 size. If the space for the stack is less than 16 bytes aslink trows a
8853 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8854 the 8051. Option 'y' for memory summary output file.
8856 Changes to sdcc (All the changes are marked with 'JCF'):
8858 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8860 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8861 overlaying area for it (uses RegBankUsed[4]).
8863 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8864 bank zero as used by default. By default aslink locates the stack
8865 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8866 the creation of the .mem file. Delegates the allocation of data area
8867 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8868 the begining of the stack area to aslink.
8870 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8871 glue() in SDCCglue.c creates an area for it.
8873 2002-09-03 Borut Razem <borut.razem AT siol.net>
8874 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8875 sdcc/src/pic/glue.c:
8876 introduced atexit() handler for teporay files removal in case of
8877 errors, assertions, ...
8879 2002-08-29 Borut Razem <borut.razem AT siol.net>
8880 * sdcc/support/cpp2/auto-host_vc_in.h:
8881 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8882 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8883 Maybe there is a similar problem with BORLANDC? It should be checked!
8885 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8886 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8887 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8888 was not executed, and the compiler (cl) launched a warning:
8889 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8891 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8892 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8894 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8895 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8897 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8898 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8899 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8900 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8901 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8902 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8903 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8904 - added Release configuration in VS projects
8905 - review of compiler an linker options
8906 - VC .exe files are generated in bin_vc directory, not to interfere
8907 with binaries generated from other projects (cygwin, mingw, bcc ...)
8909 * sdcc/src/yacc.dsp: added
8911 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8912 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8913 and insert the version number definitions from .version
8915 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8917 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8918 added - genarate auto-host.h using auto-host_vc_in.h as template
8921 removed from CVS, generated automatically
8923 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8924 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8926 2002-08-11 Borut Razem <borut.razem AT siol.net>
8927 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8929 2002-08-10 Borut Razem <borut.razem AT siol.net>
8930 * src/SDCCmain.c (main):
8931 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8932 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8933 The consequence was that some temporary files were not removed.
8936 unification of code in functions tempfilename() and tempfile():
8937 function tempnam() is defined in Visual Studio 6.0 and .NET
8939 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8941 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8942 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8943 - removed compiler command line option /WX: Treats all warnings as errors
8944 - update a list of source files, included into the project
8946 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8947 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8948 changed project type to Generic Project so that can be correcly converted to VS.NET project
8950 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8952 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8954 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8956 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8957 added return 0 statements after assert() to make compiler happy
8959 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8960 added newline in the def file to keep MSC compiler satisfied
8962 * sdcc/src/z80/gen.c:
8963 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8964 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8965 - solved MSC error in function aopDump()
8967 * sdcc_vc.h: define PREFIX as "\\sdcc"
8969 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8970 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9009 2002-03-28 Johan Knol <johan AT balder>
9011 * src/SDCCval.c: fixed bug #532436
9013 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9015 Added "char *Processor" field to the port structure.
9018 Added -p option. Allows port dependent processor to be specified.
9021 Initialized the new field char *Processor field to NULL in all ports
9024 Compiler generated registers for interrupt context saving
9025 were not getting allocated.
9027 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9030 Fixed left shift. Will promote the left side of a left shift
9031 if a) left shifting more than size of operand or b) when assigned
9032 to something size > size of left side
9034 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9036 tons of changes. Register allocation has been
9037 rewritten. Added customization for the various PICs. Flow
9038 analysis is restructured. ...
9044 Added. device.c is a PIC port hack to accomodate variations

9144 * sdcc/src/SDCCloop.c:
9145 Previous fix was not good. basic blocks that have "break" or "return" are
9146 not really partof a loop , but live ranges used in these blocks should
9147 be live thru the entire loop, so set partOfLoop but don't add them to
