1724 * (pic16_popGetTempRegCond): changed function prototype, now
1725 function takes also a bitVector argument v which holds the current
1726 set of registers that are allocated for stack access by aopForSym,
1727 registers allocated in aopForSym for accessing stack symbols are not
1728 any more part of the functions usedRegs field,
1729 * (genCall): some times aopOp is called for a stack variable to be
1730 send, aopForSym might perform the push, if this is true make sure
1731 that genCall doesn't push the variable twice by testing _G.resDirect,
1732 * (genFunction): changed testing for unspecified interrupt number
1733 from 256 to INTNO_UNSPEC,
1734 * modified selection scheme of frame pointer generation. Previously
1735 if function did use local registers a frame pointer was generated,
1736 now a frame pointer is generated only if function has arguments
1737 (that need PLUSW2 register access), or has stack arguments, or the
1738 compiler is not instructed to omit the frame pointer,
1739 * (genEndFunction): before restoring local registers that were saved
1740 in the function preamble, also restore the registers that *might*
1741 have been allocated for stack access,
1742 * (genRet): removed some old comments,
1743 * (genCmp, the active (RN's) version): added a call to the
1744 pic16_genCmp_special function to perform the compare with a more
1745 robust and optimized way,
1746 * (genInline): a feature has been added in inline code generation,
1747 which allows a wildcard variable substitution when writing inline
1748 assembly. Code is incomplete and experimental therefore undocumented,
1749 * (genCast): changed order of aopOp for result and right to allow
1750 aopForSym to directly load the result if possible,
1751 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1752 perform an optimized compare on some selected special occasions,
1753 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1754 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1755 generate an IVT any more,
1756 * src/pic16/main.c (pic16_optionsTable): added command line option
1758 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1759 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1761 * src/pic16/NOTES: Raphael Neider added in list of active developers
1762 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1763 jumptable_end to prevent bug #,
1764 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1765 inCond and outCond fields,
1766 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1767 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1768 turn off register spilling,
1769 * (packRegsForOneUse): synced with other ports' versions although it
1770 is not used currently,
1771 * (pic16_packRegisters): added an optimization while reading
1772 structure bitfields, some registers may be saved (malloc code is
1773 decreased by 80 bytes)
1775 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1777 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1778 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1779 this can be optimized more?
1781 2005-03-10 Raphael Neider <rneider AT web.de>
1783 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1784 genNearPointerGet): (hopefully) fixed access to bitfields via
1785 pointers (p->bitN = x; and x = p->bitN; failed)

2111 access stack and frame pointers. They are initially assigned to
2112 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2113 accessing SFRs. Updated all occurences of modification of stack or
2114 frame pointer in gen.c and pcode.c,
2115 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
2116 assigning of a literal value to pointers,

2422 Now 4 algorithms for mcs51 jumptable generation are used:
2423 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2457 * added libc directory. The current version of LibC contains string
2458 functions, ctype functions and macros and some functions of the
2459 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2460 be extensively tested in the future. Standard disclaimer here.

2474 * (genCmp): experimental code for new genCmp which uses PIC18's
2475 special compare&skip instructions. Initial tests fail some times
2476 with variables grater than 1 byte in size, so new code is disabled,
2477 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2479 * (genCast): began a fix to optimize the casting of a bit to another
2480 bit, now assigning a bitfield to another bitfield will fail, sorry,

2495 * src/pic16/ralloc.c (allocReg): add preliminary support for
2496 supporting a limited set of temporary registers,

5505 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5506 loaded with the linker search paths (-L arguments) and the libraries
5507 to be linked with the current source (-l arguments). Changes
5508 currently will affect only the pic16 port.
5509 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5510 include path the port specific paths and port specific libraries,
5511 * gplink command now contains the $3 argument,
5512 * src/pic16/device.h,
5513 * src/pic16/device.c,: structure PIC_device is made public and
5514 renamed to PIC16_device, the same for variable Pics which is renamed

5529 Documenting changes from previous commits.
5530 * configure.in (version 1.56),
5531 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5532 when generating output files to configure the pic16 library,
5533 but now I've commented it out, since gputils aren't installed in the
5534 SF compile farm, so library won't compile
5536 * device/lib/Makefile.in (version 1.56): initially I've added in
5537 target 'all' the prerequestive 'model-pic16' so it compiled the
5538 pic16 library, but now I've commented it out for the same reasons
5540 * added targets 'model-pic16' and 'objects-pic16' to compile the
5542 * added target 'port-specific-objects-pic16' to handle the
5543 generated libraries and copy them into the build/ directory
5544 * added target 'clean-intermediate-pic16' to clean intermediate
5545 files into pic16 directory
5546 * in target 'installdirs' added line to create directory pic16 in

5568 option so that it actually works. Made it specific to the z80, since
5569 the gbz80 doesn't have these kinds of I/O ports.
5571 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5573 * device/include/z180.h,

5600 data are now emitted in sorted order to reduce section naming,
5601 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5602 weren't marked as being in the access bank,

5793 LEFT_OP (left shift)
5795 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5797 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5798 (default behaviour).
5800 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5802 A python script to validate compiler diagnostic messages. It can be
5803 used to verify that sdcc complains about bad c source code and
5804 gives a good location of the error.
5805 * support/valdiag/Makefile,
5806 * support/valdiag/valdiag.py,
5807 * support/valdiag/tests/*

5826 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5828 * sdcc.spec: updated
5829 * device/include/Makefile.in: don't install CVS directories
5830 * device/lib/Makefile.in: added removal of CVS directories after install
5831 * doc/Makefile: fixed install, added local_icons
5832 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5833 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5834 * src/ds390/gen.c (genRightShift): fixed bug #870788

5837 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5839 PIC16 port related changes:
5840 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5841 added variable stackPos,
5843 * gen.c: genCall, assignResultValue: added support for
5844 pushing/retrieving function parameters to/from stack,
5845 genFunction,genEndFunction: setup stack frame for the
5847 genAddrOf: will be changed according to bug 863624
5849 * added files genutils.c and genutils.h which contain gen*
5850 debugged and optimised functions extracted from gen.c
5852 * glue.c: added variable 'externs' which holds extern symbols,
5853 pic16emitRegularMap: is modified to properly handle relocatable
5854 symbols under the new scheme,
5855 pic16createInterruptVect: is modified
5856 pic16printPublics: is modified to emit 'global' assembler directives,
5857 added pic16_printExterns to print extern symbols,
5858 pic16glue: initializes stack/frame pointer in the beginning of
5859 the assembly output. Temporary hack, will be corrected later,
5860 because gplink yet does not support stack and SDCC does not
5861 yet support a type of crt0.o object to create the final binary.
5863 * Removed many lines that contain 8051 legacy code.
5864 * The code is finally placed under a 'code' directive.
5865 * Added port specific options.
5867 * _process_pragma: simplified since now we do not need *special*
5868 include file to define SFR registers. But a separate header
5869 will be needed. This will be developed later.
5870 * _pic16_parseOptions: added, parses port specific options:
5871 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5872 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5873 --preplace-udata-with=
5875 * _pic16_setDefaultOptions: modified to initialize section names,
5876 but hack is temporarly out of order since it needs improvement.
5877 * _pic16_genAssemblerPreamble: configuration words are emitted by
5878 their address instead of their name. This part is incomplete and
5879 supports only the 18Fxx2 devices. Other devices will emit an error
5880 during assembly since they do not contain the same set of config
5882 * _pic16_genIVT: is modified,
5884 * pcode.c: added definitions for some hardware registers that are needed
5886 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5887 All PCI entries are updated. Now LFSR is supported.
5888 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5889 * added pic16_newpCodeOpLit2 to support instructions with
5890 two literal arguments
5891 * pic16_pCode2str: corrected code that emits assembler instructions
5892 with two literal operands and those that have an access bit modifier
5893 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5894 this fixes a bug which caused some labels to be lost, when an
5895 assembler directive was added, i.e. banksel,
5896 * pic16_FixRegisterBanking: improved logic that causes the insertion
5898 * InlineFunction: functions that are called once, are not any more
5899 inlined. This can be a port option in the future,
5901 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5903 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5904 hold the corresponding uninitialized symbols,
5905 * pic16_allocProcessorRegister: registers have explicit marked the
5907 * pic16_allocInternalRegister: registers are explicit marked as
5909 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5910 processing list, so bit registers were lost,
5913 * ralloc.h: added field 'accessBank' and original symbol operand
5914 in register definition,
5915 * removed the field isMapped from register definition,
5917 ** Several functions have been removed from various sources:
5918 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5919 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5920 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5921 pic16_assignRelocatableRegisters
5923 ** others have been introduced:
5924 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5925 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5927 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5929 * support/scripts/inc2h.pl: changed definition of BIT_AT
5930 to emit 'sbit at' instead of 'bit at'. This was a request.
5932 PIC16 port related preliminary changes:
5933 * gen.c: prefixed function popRegFromString with
5934 pic16_ and all references to it corrected
5935 * pcode.c: all pic16_pc_* hardware registers prefixed
5936 with underscore (_),
5937 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5938 * ralloc.c: newReg(): when register is REG_SFR then
5939 set address to rIdx,
5940 pic16_allocProcessorRegister(): marks register wasUsed=0
5941 pic16_writeUsedRegs(): added a call to assign processor
5942 registers via pic16_assignFixedRegisters
5944 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5946 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5947 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5948 variables in unused register banks. Also the SSEG is placed
5949 wherever there is enough space for it, and IDATA can be anywhere
5950 in internal RAM. For now compile using -Wl-Y[stack_size].
5951 The mem file is different for this option as well, since it
5952 makes no sense of talking about DSEG lenght.
5954 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5956 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5957 in certain cases, e.g. when ROM assignment, patch provided
5958 from Albert den Haan.
5960 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6962 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6963 fetching of the pointer
6964 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6965 copied from genNearPointerSet()
6966 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6967 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6983 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6984 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6985 type for bits was changed. It resulted in bit variables becoming
6986 global, which is not permitted in PIC 14 assembly output.

7003 A few small changes that speed up the peephole optimizer.
7007 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7009 Try to make the peephole optimizer smarter by maintaining
7010 an association between the assembly source code and the
7011 iCodes that originated them. Put this information to use
7012 with a new peephole rule condition "notVolatile" so that
7013 the rules can be aggressive yet still safe.
7018 * src/mcs51/peeph.def
7020 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7024 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7025 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7026 if the left or right operand symbols have the accuse flag set.
7028 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7030 Changed the type of the result of the ! (NOT) operator to char;
7031 previously it returned the same type as the source. This allows
7032 us to eliminate all the genFloatNot functions (all of its target
7033 implementations were very buggy) since !float can use the same

7046 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7047 during interrupts. Ensure WSAVE is located at a shared bank address.
7048 2. Fixed page selection in some places
7049 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7050 the registers name strings.
7051 4. Fixed "signed / unsigned compare" compiler warnings.
7052 5. The PIC port manages its own allocation of the general purpose
7053 registers, but makes no attempt to reuse them. As a result when
7054 compiling it soon runs out of general purpose registers. Some
7055 additional code was added to the files pcode.c and device.c to walk
7056 through the function call tree and rename the registers so that they
7066 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7073 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7075 Made bitfield a distinct type from bit so that bitfields
7076 convert as per ANSI C and bits retain their traditional
7077 boolean style behaviour. Implemented bitfield support in
7085 * src/ds390/gen.c: bit v bitfield split
7086 * src/z80/gen.c: New support for bitfields
7087 * support/regression/tests/bitfields.c: reenabled z80,
7090 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7092 Rules 246.x, 247.x relate to bitfields, the others speed up
7093 access to xdata mapped I/O devices.
7095 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7097 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7099 Cleaned up genPackBits and genUnpackBits and added two helper
7100 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7101 for literal assignments in genPackBits (thanks to Frieder for
7107 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7109 Fixed bug #748310 (pointer to function type mishandled when the
7110 function name is omitted). Also fixed a SIGSEGV when a function
7111 attribute (reentrant, etc) is used on a non-function or on a
7112 function but misplaced before the parameter list.

7139 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7141 Made the constant following the "interrupt" keyword optional. If
7142 omitted, the function will not automatically be given an entry
7143 in the interrupt vector table (similar to #pragma NOIV, but
7144 less syntacticly kludgy). The interrupt number is also now
7145 range checked. Also fixed a bug in the high order bit example

7676 messages from optionsTable when a port is not configured, added
7677 support for the PIc16 port in the ports table, when executing
7678 the compiler with no port specified on command line, a default
7679 port is selected with the new macro DEFAULT_PORT which is
7680 defined in port.h, in setDefaultOptions() linkOptions is removed
7681 from initialization assignment, since now it is a set,
7682 parseCmdLine uses setParseWithComma for linkOptions, in
7683 linkEdit() linkOptions are accessed with new function indexSet()
7684 which returns the i'th item of a set variable. See SDCCset.c, in
7685 linkEdit() when calling buildCmdLine(), added linkOptions as
7686 last argument. Now users can pass arguments to gplink via the
7687 -Wl option, main() uses pic16glue() to glue up pic16 programs

7701 gpasm complaining and test the linkage with gplink, _linkCmd and
7702 _asmCmd changed to be more gplink and gpasm friendly
7703 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7704 produced an error when parsed, peep rule 12 is added to utilize
7705 movff, but it is commented out since the pCode does not support
7706 yet a command with 2 address arguments
7708 2003-05-18 <johan AT balder>
7710 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8743 2003-01-06 <johan AT balder>
8745 * src/SDCCicode.c: fixed array add
8747 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8748 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8749 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8751 2003-01-04 <johan AT balder>
8753 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8755 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8756 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8758 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8759 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8768 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8769 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8771 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8773 * in \sdcc\as\mcs51\ changed these files in order to create an
8774 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8775 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8776 following files to include the previous two files: aslink.dsp,
8777 Makefile.aslink, Makefile.bcc, and Makefile.in.
8779 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8780 .adb instead of .cdb
8782 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8784 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8785 value from option --iram-size.
8787 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8789 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8792 2002-09-18 <wiml AT hhhh.org>
8794 * SDCClrange.h: exposed setFromRange() and setToRange()
8795 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8796 packRegsForAccUse() (bug 542397)
8797 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8798 multiple times and emitting the fetch operations more than once
8799 added aopGetUsesAcc() function to allow binary operators to
8800 fetch their operands in the correct order; made genMinus() emit
8801 compact code for X = LITERAL - Y
8803 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8804 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8805 sprintf() in line 1267.
8807 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8808 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8811 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8812 Changes to aslink (All the changes are marked with 'JCF'):
8814 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8817 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8818 area BSEG. Also moves, if possible, the DATA area down into the internal
8819 ram so more space is available.
8821 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8824 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8825 not bytes. Function summary() which creates a memory usage summary
8826 file with extension .mem. Reports of overlaping stack and small stack
8827 size. If the space for the stack is less than 16 bytes aslink trows a
8830 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8831 the 8051. Option 'y' for memory summary output file.
8833 Changes to sdcc (All the changes are marked with 'JCF'):
8835 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8837 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8838 overlaying area for it (uses RegBankUsed[4]).
8840 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8841 bank zero as used by default. By default aslink locates the stack
8842 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8843 the creation of the .mem file. Delegates the allocation of data area
8844 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8845 the begining of the stack area to aslink.
8847 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8848 glue() in SDCCglue.c creates an area for it.
8850 2002-09-03 Borut Razem <borut.razem AT siol.net>
8851 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8852 sdcc/src/pic/glue.c:
8853 introduced atexit() handler for teporay files removal in case of
8854 errors, assertions, ...
8856 2002-08-29 Borut Razem <borut.razem AT siol.net>
8857 * sdcc/support/cpp2/auto-host_vc_in.h:
8858 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8859 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8860 Maybe there is a similar problem with BORLANDC? It should be checked!
8862 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8863 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8864 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8865 was not executed, and the compiler (cl) launched a warning:
8866 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8868 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8869 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8871 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8872 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8874 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8875 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8876 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8877 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8878 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8879 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8880 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8881 - added Release configuration in VS projects
8882 - review of compiler an linker options
8883 - VC .exe files are generated in bin_vc directory, not to interfere
8884 with binaries generated from other projects (cygwin, mingw, bcc ...)
8886 * sdcc/src/yacc.dsp: added
8888 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8889 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8890 and insert the version number definitions from .version
8892 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8894 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8895 added - genarate auto-host.h using auto-host_vc_in.h as template
8898 removed from CVS, generated automatically
8900 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8901 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8903 2002-08-11 Borut Razem <borut.razem AT siol.net>
8904 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8906 2002-08-10 Borut Razem <borut.razem AT siol.net>
8907 * src/SDCCmain.c (main):
8908 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8909 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8910 The consequence was that some temporary files were not removed.
8913 unification of code in functions tempfilename() and tempfile():
8914 function tempnam() is defined in Visual Studio 6.0 and .NET
8916 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8918 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8919 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8920 - removed compiler command line option /WX: Treats all warnings as errors
8921 - update a list of source files, included into the project
8923 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8924 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8925 changed project type to Generic Project so that can be correcly converted to VS.NET project
8927 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8929 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8931 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8933 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8934 added return 0 statements after assert() to make compiler happy
8936 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8937 added newline in the def file to keep MSC compiler satisfied
8939 * sdcc/src/z80/gen.c:
8940 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8941 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8942 - solved MSC error in function aopDump()
8944 * sdcc_vc.h: define PREFIX as "\\sdcc"
8946 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8947 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8949 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8950 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8951 - Rewrote the register banking algorithm.
8952 - Added pCode live-range analysis to registers (for now, only non-used and
8953 singly-used registers optimized away)
8955 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8957 * 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.
8959 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8960 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8962 2002-04-22 Michael Hope <michaelh AT vroom>

8982 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8984 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8986 2002-03-28 Johan Knol <johan AT balder>
8988 * src/SDCCval.c: fixed bug #532436
8990 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8992 Added "char *Processor" field to the port structure.
8995 Added -p option. Allows port dependent processor to be specified.
8998 Initialized the new field char *Processor field to NULL in all ports
9001 Compiler generated registers for interrupt context saving
9002 were not getting allocated.
9004 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9007 Fixed left shift. Will promote the left side of a left shift
9008 if a) left shifting more than size of operand or b) when assigned
9009 to something size > size of left side
9011 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9013 tons of changes. Register allocation has been
9014 rewritten. Added customization for the various PICs. Flow
9015 analysis is restructured. ...
9021 Added. device.c is a PIC port hack to accomodate variations
9024 2002-03-13 Michael Hope <michaelh AT vroom>
9026 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9028 2002-03-04 johanknol <johanknol AT manik>
9030 * /src/SDCCval.c: fixed
9032 const unsigned char arr[][2] = { { 0, 1 } };
9033 t18.c:1: error: Initializer element is not constant
9035 2002-03-04 bela <bela AT manik>
9037 * /device/include/mcs51reg.h:
9038 ds89c420 register definition update
9040 2002-03-03 <johan AT FRIJA>

9119 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9121 * sdcc/src/SDCCloop.c:
9122 Previous fix was not good. basic blocks that have "break" or "return" are
9123 not really partof a loop , but live ranges used in these blocks should
9124 be live thru the entire loop, so set partOfLoop but don't add them to
9127 2002-02-21 <johan AT FRIJA>
9129 * src/SDCCcse.c: fixed bug #514308
9131 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9134 Fixed BUG #519583. If a conditional block ended in a return/break
9135 statement inside a loop, it was not being considered part of the loop.
9137 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9139 2002-02-10 Karl Bongers <karl AT turbobit.com>
