1734 * (aopForSym): added an optimization to directly store in stack of
1735 the operand of a SEND iCode,
1736 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1737 but as registers instead (AOP_REG) using the fReturnIdx array,
1738 * (pic16_freeAsmop): remove the freed register from the
1739 _G.sregsAlloc field,
1740 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1741 a compare of 'WREG',
1742 * (pic16_popGetTempRegCond): changed function prototype, now
1743 function takes also a bitVector argument v which holds the current
1744 set of registers that are allocated for stack access by aopForSym,
1745 registers allocated in aopForSym for accessing stack symbols are not
1746 any more part of the functions usedRegs field,
1747 * (genCall): some times aopOp is called for a stack variable to be
1748 send, aopForSym might perform the push, if this is true make sure
1749 that genCall doesn't push the variable twice by testing _G.resDirect,
1750 * (genFunction): changed testing for unspecified interrupt number
1751 from 256 to INTNO_UNSPEC,
1752 * modified selection scheme of frame pointer generation. Previously
1753 if function did use local registers a frame pointer was generated,
1754 now a frame pointer is generated only if function has arguments
1755 (that need PLUSW2 register access), or has stack arguments, or the
1756 compiler is not instructed to omit the frame pointer,
1757 * (genEndFunction): before restoring local registers that were saved
1758 in the function preamble, also restore the registers that *might*
1759 have been allocated for stack access,
1760 * (genRet): removed some old comments,
1761 * (genCmp, the active (RN's) version): added a call to the
1762 pic16_genCmp_special function to perform the compare with a more
1763 robust and optimized way,
1764 * (genInline): a feature has been added in inline code generation,
1765 which allows a wildcard variable substitution when writing inline
1766 assembly. Code is incomplete and experimental therefore undocumented,
1767 * (genCast): changed order of aopOp for result and right to allow
1768 aopForSym to directly load the result if possible,
1769 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1770 perform an optimized compare on some selected special occasions,
1771 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1772 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1773 generate an IVT any more,
1774 * src/pic16/main.c (pic16_optionsTable): added command line option
1776 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1777 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1779 * src/pic16/NOTES: Raphael Neider added in list of active developers
1780 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1781 jumptable_end to prevent bug #,
1782 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1783 inCond and outCond fields,
1784 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1785 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1786 turn off register spilling,
1787 * (packRegsForOneUse): synced with other ports' versions although it
1788 is not used currently,
1789 * (pic16_packRegisters): added an optimization while reading
1790 structure bitfields, some registers may be saved (malloc code is
1791 decreased by 80 bytes)
1793 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1795 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1796 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1797 this can be optimized more?
1799 2005-03-10 Raphael Neider <rneider AT web.de>
1801 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1802 genNearPointerGet): (hopefully) fixed access to bitfields via
1803 pointers (p->bitN = x; and x = p->bitN; failed)

2129 access stack and frame pointers. They are initially assigned to
2130 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2131 accessing SFRs. Updated all occurences of modification of stack or
2132 frame pointer in gen.c and pcode.c,

2437 Adding support for replacing ljmps with sjmps in jumptables
2438 generated for switch statements. For now you need to set the
2439 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2440 Now 4 algorithms for mcs51 jumptable generation are used:
2441 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2475 * added libc directory. The current version of LibC contains string
2476 functions, ctype functions and macros and some functions of the
2477 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2478 be extensively tested in the future. Standard disclaimer here.

2491 * (pic16_storeForReturn): optimized return of 0,
2492 * (genCmp): experimental code for new genCmp which uses PIC18's
2493 special compare&skip instructions. Initial tests fail some times
2494 with variables grater than 1 byte in size, so new code is disabled,
2495 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2497 * (genCast): began a fix to optimize the casting of a bit to another
2498 bit, now assigning a bitfield to another bitfield will fail, sorry,

2512 registers when it shouldn't,
2513 * src/pic16/ralloc.c (allocReg): add preliminary support for
2514 supporting a limited set of temporary registers,
2516 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5523 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5524 loaded with the linker search paths (-L arguments) and the libraries
5525 to be linked with the current source (-l arguments). Changes
5526 currently will affect only the pic16 port.
5527 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5528 include path the port specific paths and port specific libraries,
5529 * gplink command now contains the $3 argument,
5530 * src/pic16/device.h,
5531 * src/pic16/device.c,: structure PIC_device is made public and
5532 renamed to PIC16_device, the same for variable Pics which is renamed

5547 Documenting changes from previous commits.
5548 * configure.in (version 1.56),
5549 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5550 when generating output files to configure the pic16 library,
5551 but now I've commented it out, since gputils aren't installed in the
5552 SF compile farm, so library won't compile
5554 * device/lib/Makefile.in (version 1.56): initially I've added in
5555 target 'all' the prerequestive 'model-pic16' so it compiled the
5556 pic16 library, but now I've commented it out for the same reasons
5558 * added targets 'model-pic16' and 'objects-pic16' to compile the
5560 * added target 'port-specific-objects-pic16' to handle the
5561 generated libraries and copy them into the build/ directory
5562 * added target 'clean-intermediate-pic16' to clean intermediate
5563 files into pic16 directory
5564 * in target 'installdirs' added line to create directory pic16 in

5586 option so that it actually works. Made it specific to the z80, since
5587 the gbz80 doesn't have these kinds of I/O ports.
5589 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5591 * device/include/z180.h,

5618 data are now emitted in sorted order to reduce section naming,
5619 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5620 weren't marked as being in the access bank,

5813 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5815 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5816 (default behaviour).
5818 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5820 A python script to validate compiler diagnostic messages. It can be
5821 used to verify that sdcc complains about bad c source code and
5822 gives a good location of the error.
5823 * support/valdiag/Makefile,
5824 * support/valdiag/valdiag.py,
5825 * support/valdiag/tests/*

5842 Bug reported from Jesus Calvino-Fraga
5844 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5846 * sdcc.spec: updated
5847 * device/include/Makefile.in: don't install CVS directories
5848 * device/lib/Makefile.in: added removal of CVS directories after install
5849 * doc/Makefile: fixed install, added local_icons
5850 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5851 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5852 * src/ds390/gen.c (genRightShift): fixed bug #870788

5855 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5857 PIC16 port related changes:
5858 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5859 added variable stackPos,
5861 * gen.c: genCall, assignResultValue: added support for
5862 pushing/retrieving function parameters to/from stack,
5863 genFunction,genEndFunction: setup stack frame for the
5865 genAddrOf: will be changed according to bug 863624
5867 * added files genutils.c and genutils.h which contain gen*
5868 debugged and optimised functions extracted from gen.c
5870 * glue.c: added variable 'externs' which holds extern symbols,
5871 pic16emitRegularMap: is modified to properly handle relocatable
5872 symbols under the new scheme,
5873 pic16createInterruptVect: is modified
5874 pic16printPublics: is modified to emit 'global' assembler directives,
5875 added pic16_printExterns to print extern symbols,
5876 pic16glue: initializes stack/frame pointer in the beginning of
5877 the assembly output. Temporary hack, will be corrected later,
5878 because gplink yet does not support stack and SDCC does not
5879 yet support a type of crt0.o object to create the final binary.
5881 * Removed many lines that contain 8051 legacy code.
5882 * The code is finally placed under a 'code' directive.
5883 * Added port specific options.
5885 * _process_pragma: simplified since now we do not need *special*
5886 include file to define SFR registers. But a separate header
5887 will be needed. This will be developed later.
5888 * _pic16_parseOptions: added, parses port specific options:
5889 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5890 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5891 --preplace-udata-with=
5893 * _pic16_setDefaultOptions: modified to initialize section names,
5894 but hack is temporarly out of order since it needs improvement.
5895 * _pic16_genAssemblerPreamble: configuration words are emitted by
5896 their address instead of their name. This part is incomplete and
5897 supports only the 18Fxx2 devices. Other devices will emit an error
5898 during assembly since they do not contain the same set of config
5900 * _pic16_genIVT: is modified,
5902 * pcode.c: added definitions for some hardware registers that are needed
5904 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5905 All PCI entries are updated. Now LFSR is supported.
5906 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5907 * added pic16_newpCodeOpLit2 to support instructions with
5908 two literal arguments
5909 * pic16_pCode2str: corrected code that emits assembler instructions
5910 with two literal operands and those that have an access bit modifier
5911 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5912 this fixes a bug which caused some labels to be lost, when an
5913 assembler directive was added, i.e. banksel,
5914 * pic16_FixRegisterBanking: improved logic that causes the insertion
5916 * InlineFunction: functions that are called once, are not any more
5917 inlined. This can be a port option in the future,
5919 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5921 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5922 hold the corresponding uninitialized symbols,
5923 * pic16_allocProcessorRegister: registers have explicit marked the
5925 * pic16_allocInternalRegister: registers are explicit marked as
5927 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5928 processing list, so bit registers were lost,
5931 * ralloc.h: added field 'accessBank' and original symbol operand
5932 in register definition,
5933 * removed the field isMapped from register definition,
5935 ** Several functions have been removed from various sources:
5936 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5937 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5938 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5939 pic16_assignRelocatableRegisters
5941 ** others have been introduced:
5942 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5943 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5945 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5947 * support/scripts/inc2h.pl: changed definition of BIT_AT
5948 to emit 'sbit at' instead of 'bit at'. This was a request.
5950 PIC16 port related preliminary changes:
5951 * gen.c: prefixed function popRegFromString with
5952 pic16_ and all references to it corrected
5953 * pcode.c: all pic16_pc_* hardware registers prefixed
5954 with underscore (_),
5955 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5956 * ralloc.c: newReg(): when register is REG_SFR then
5957 set address to rIdx,
5958 pic16_allocProcessorRegister(): marks register wasUsed=0
5959 pic16_writeUsedRegs(): added a call to assign processor
5960 registers via pic16_assignFixedRegisters
5962 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5964 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5965 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5966 variables in unused register banks. Also the SSEG is placed
5967 wherever there is enough space for it, and IDATA can be anywhere
5968 in internal RAM. For now compile using -Wl-Y[stack_size].
5969 The mem file is different for this option as well, since it
5970 makes no sense of talking about DSEG lenght.
5972 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5974 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5975 in certain cases, e.g. when ROM assignment, patch provided
5976 from Albert den Haan.
5978 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6981 fetching of the pointer
6982 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6983 copied from genNearPointerSet()
6984 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6985 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7001 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7002 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7003 type for bits was changed. It resulted in bit variables becoming
7004 global, which is not permitted in PIC 14 assembly output.
7006 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7008 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7021 A few small changes that speed up the peephole optimizer.
7025 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7027 Try to make the peephole optimizer smarter by maintaining
7028 an association between the assembly source code and the
7029 iCodes that originated them. Put this information to use
7030 with a new peephole rule condition "notVolatile" so that
7031 the rules can be aggressive yet still safe.
7036 * src/mcs51/peeph.def
7038 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7042 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7043 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7044 if the left or right operand symbols have the accuse flag set.
7046 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7048 Changed the type of the result of the ! (NOT) operator to char;
7049 previously it returned the same type as the source. This allows
7050 us to eliminate all the genFloatNot functions (all of its target
7051 implementations were very buggy) since !float can use the same
7054 * src/SDCCicode.c (ast2iCode): ! returns char

7061 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7063 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7064 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7065 during interrupts. Ensure WSAVE is located at a shared bank address.
7066 2. Fixed page selection in some places
7067 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7068 the registers name strings.
7069 4. Fixed "signed / unsigned compare" compiler warnings.
7070 5. The PIC port manages its own allocation of the general purpose
7071 registers, but makes no attempt to reuse them. As a result when
7072 compiling it soon runs out of general purpose registers. Some
7073 additional code was added to the files pcode.c and device.c to walk
7074 through the function call tree and rename the registers so that they
7084 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7085 genPlus() & genMinus() when the result is the same as left or right

7091 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7093 Made bitfield a distinct type from bit so that bitfields
7094 convert as per ANSI C and bits retain their traditional
7095 boolean style behaviour. Implemented bitfield support in
7103 * src/ds390/gen.c: bit v bitfield split
7104 * src/z80/gen.c: New support for bitfields
7105 * support/regression/tests/bitfields.c: reenabled z80,
7108 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7110 Rules 246.x, 247.x relate to bitfields, the others speed up
7111 access to xdata mapped I/O devices.
7113 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7115 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7117 Cleaned up genPackBits and genUnpackBits and added two helper
7118 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7119 for literal assignments in genPackBits (thanks to Frieder for
7125 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7127 Fixed bug #748310 (pointer to function type mishandled when the
7128 function name is omitted). Also fixed a SIGSEGV when a function
7129 attribute (reentrant, etc) is used on a non-function or on a
7130 function but misplaced before the parameter list.
7132 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7134 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7135 * support/Util/SDCCerr.h,
7136 * support/Util/SDCCerr.c: Added func attr misuse error msg

7157 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7159 Made the constant following the "interrupt" keyword optional. If
7160 omitted, the function will not automatically be given an entry
7161 in the interrupt vector table (similar to #pragma NOIV, but
7162 less syntacticly kludgy). The interrupt number is also now
7163 range checked. Also fixed a bug in the high order bit example

7179 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7181 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7182 be re-activated by defining REDUCE_LITERALS)
7183 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7184 unsigned, but are signed by default
7185 * src/SDCCval.c (constVal): rearranged
7186 * src/SDCCval.c (valMod): preliminary fix
7187 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7693 added if/endif conditional macros to remove options help
7694 messages from optionsTable when a port is not configured, added
7695 support for the PIc16 port in the ports table, when executing
7696 the compiler with no port specified on command line, a default
7697 port is selected with the new macro DEFAULT_PORT which is
7698 defined in port.h, in setDefaultOptions() linkOptions is removed
7699 from initialization assignment, since now it is a set,
7700 parseCmdLine uses setParseWithComma for linkOptions, in
7701 linkEdit() linkOptions are accessed with new function indexSet()
7702 which returns the i'th item of a set variable. See SDCCset.c, in
7703 linkEdit() when calling buildCmdLine(), added linkOptions as
7704 last argument. Now users can pass arguments to gplink via the
7705 -Wl option, main() uses pic16glue() to glue up pic16 programs

7719 gpasm complaining and test the linkage with gplink, _linkCmd and
7720 _asmCmd changed to be more gplink and gpasm friendly
7721 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7722 produced an error when parsed, peep rule 12 is added to utilize
7723 movff, but it is commented out since the pCode does not support
7724 yet a command with 2 address arguments
7726 2003-05-18 <johan AT balder>
7728 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7755 2003-05-11 Borut Razem <borut.razem AT siol.net>
7757 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8767 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8769 2003-01-04 <johan AT balder>
8771 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8773 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8774 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8789 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8791 * in \sdcc\as\mcs51\ changed these files in order to create an
8792 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8793 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8794 following files to include the previous two files: aslink.dsp,
8795 Makefile.aslink, Makefile.bcc, and Makefile.in.
8797 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8798 .adb instead of .cdb
8800 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8802 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8803 value from option --iram-size.
8805 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8807 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8810 2002-09-18 <wiml AT hhhh.org>
8812 * SDCClrange.h: exposed setFromRange() and setToRange()
8813 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8814 packRegsForAccUse() (bug 542397)
8815 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8816 multiple times and emitting the fetch operations more than once
8817 added aopGetUsesAcc() function to allow binary operators to
8818 fetch their operands in the correct order; made genMinus() emit
8819 compact code for X = LITERAL - Y
8821 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8822 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8823 sprintf() in line 1267.
8825 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8826 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8829 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8830 Changes to aslink (All the changes are marked with 'JCF'):
8832 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8835 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8836 area BSEG. Also moves, if possible, the DATA area down into the internal
8837 ram so more space is available.
8839 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8842 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8843 not bytes. Function summary() which creates a memory usage summary
8844 file with extension .mem. Reports of overlaping stack and small stack
8845 size. If the space for the stack is less than 16 bytes aslink trows a
8848 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8849 the 8051. Option 'y' for memory summary output file.
8851 Changes to sdcc (All the changes are marked with 'JCF'):
8853 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8855 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8856 overlaying area for it (uses RegBankUsed[4]).
8858 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8859 bank zero as used by default. By default aslink locates the stack
8860 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8861 the creation of the .mem file. Delegates the allocation of data area
8862 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8863 the begining of the stack area to aslink.
8865 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8866 glue() in SDCCglue.c creates an area for it.
8868 2002-09-03 Borut Razem <borut.razem AT siol.net>
8869 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8870 sdcc/src/pic/glue.c:
8871 introduced atexit() handler for teporay files removal in case of
8872 errors, assertions, ...
8874 2002-08-29 Borut Razem <borut.razem AT siol.net>
8875 * sdcc/support/cpp2/auto-host_vc_in.h:
8876 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8877 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8878 Maybe there is a similar problem with BORLANDC? It should be checked!
8880 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8881 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8882 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8883 was not executed, and the compiler (cl) launched a warning:
8884 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8886 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8887 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8889 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8890 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8892 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8893 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8894 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8895 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8896 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8897 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8898 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8899 - added Release configuration in VS projects
8900 - review of compiler an linker options
8901 - VC .exe files are generated in bin_vc directory, not to interfere
8902 with binaries generated from other projects (cygwin, mingw, bcc ...)
8904 * sdcc/src/yacc.dsp: added
8906 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8907 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8908 and insert the version number definitions from .version
8910 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8912 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8913 added - genarate auto-host.h using auto-host_vc_in.h as template
8916 removed from CVS, generated automatically
8918 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8919 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8921 2002-08-11 Borut Razem <borut.razem AT siol.net>
8922 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8924 2002-08-10 Borut Razem <borut.razem AT siol.net>
8925 * src/SDCCmain.c (main):
8926 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8927 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8928 The consequence was that some temporary files were not removed.
8931 unification of code in functions tempfilename() and tempfile():
8932 function tempnam() is defined in Visual Studio 6.0 and .NET
8934 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8936 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8937 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8938 - removed compiler command line option /WX: Treats all warnings as errors
8939 - update a list of source files, included into the project
8941 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8942 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8943 changed project type to Generic Project so that can be correcly converted to VS.NET project
8945 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8947 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8949 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8951 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8952 added return 0 statements after assert() to make compiler happy
8954 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8955 added newline in the def file to keep MSC compiler satisfied
8957 * sdcc/src/z80/gen.c:
8958 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8959 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8960 - solved MSC error in function aopDump()
8962 * sdcc_vc.h: define PREFIX as "\\sdcc"
8964 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8965 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8968 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8969 - Rewrote the register banking algorithm.
8970 - Added pCode live-range analysis to registers (for now, only non-used and
8971 singly-used registers optimized away)
8973 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8975 * 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.

9004 2002-03-28 Johan Knol <johan AT balder>
9006 * src/SDCCval.c: fixed bug #532436
9008 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9010 Added "char *Processor" field to the port structure.
9013 Added -p option. Allows port dependent processor to be specified.
9016 Initialized the new field char *Processor field to NULL in all ports
9019 Compiler generated registers for interrupt context saving
9020 were not getting allocated.
9022 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9025 Fixed left shift. Will promote the left side of a left shift
9026 if a) left shifting more than size of operand or b) when assigned
9027 to something size > size of left side
9029 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9031 tons of changes. Register allocation has been
9032 rewritten. Added customization for the various PICs. Flow
9033 analysis is restructured. ...
9039 Added. device.c is a PIC port hack to accomodate variations

9140 Previous fix was not good. basic blocks that have "break" or "return" are
9141 not really partof a loop , but live ranges used in these blocks should
9142 be live thru the entire loop, so set partOfLoop but don't add them to
