1736 moved to level 0 and declared as static. Also they are explicit
1737 placed in access bank. This was necessery because some times they
1738 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1739 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1740 optimizations. Currently only compare to unsigned char is implemented,
1741 * src/pic16/gen.c: added fReturnIdx array,
1742 * (struct resolvedIfx) is moved to gen.h and made public,
1743 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1744 * (aopForSym): added an optimization to directly store in stack of
1745 the operand of a SEND iCode,
1746 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1747 but as registers instead (AOP_REG) using the fReturnIdx array,
1748 * (pic16_freeAsmop): remove the freed register from the
1749 _G.sregsAlloc field,
1750 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1751 a compare of 'WREG',
1752 * (pic16_popGetTempRegCond): changed function prototype, now
1753 function takes also a bitVector argument v which holds the current
1754 set of registers that are allocated for stack access by aopForSym,
1755 registers allocated in aopForSym for accessing stack symbols are not
1756 any more part of the functions usedRegs field,
1757 * (genCall): some times aopOp is called for a stack variable to be
1758 send, aopForSym might perform the push, if this is true make sure
1759 that genCall doesn't push the variable twice by testing _G.resDirect,
1760 * (genFunction): changed testing for unspecified interrupt number
1761 from 256 to INTNO_UNSPEC,
1762 * modified selection scheme of frame pointer generation. Previously
1763 if function did use local registers a frame pointer was generated,
1764 now a frame pointer is generated only if function has arguments
1765 (that need PLUSW2 register access), or has stack arguments, or the
1766 compiler is not instructed to omit the frame pointer,
1767 * (genEndFunction): before restoring local registers that were saved
1768 in the function preamble, also restore the registers that *might*
1769 have been allocated for stack access,
1770 * (genRet): removed some old comments,
1771 * (genCmp, the active (RN's) version): added a call to the
1772 pic16_genCmp_special function to perform the compare with a more
1773 robust and optimized way,
1774 * (genInline): a feature has been added in inline code generation,
1775 which allows a wildcard variable substitution when writing inline
1776 assembly. Code is incomplete and experimental therefore undocumented,
1777 * (genCast): changed order of aopOp for result and right to allow
1778 aopForSym to directly load the result if possible,
1779 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1780 perform an optimized compare on some selected special occasions,
1781 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1782 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1783 generate an IVT any more,
1784 * src/pic16/main.c (pic16_optionsTable): added command line option
1786 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1787 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1789 * src/pic16/NOTES: Raphael Neider added in list of active developers
1790 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1791 jumptable_end to prevent bug #,
1792 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1793 inCond and outCond fields,
1794 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1795 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1796 turn off register spilling,
1797 * (packRegsForOneUse): synced with other ports' versions although it
1798 is not used currently,
1799 * (pic16_packRegisters): added an optimization while reading
1800 structure bitfields, some registers may be saved (malloc code is
1801 decreased by 80 bytes)
1803 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1805 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1806 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1807 this can be optimized more?
1809 2005-03-10 Raphael Neider <rneider AT web.de>
1811 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1812 genNearPointerGet): (hopefully) fixed access to bitfields via
1813 pointers (p->bitN = x; and x = p->bitN; failed)

2140 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2141 accessing SFRs. Updated all occurences of modification of stack or
2142 frame pointer in gen.c and pcode.c,

2447 Adding support for replacing ljmps with sjmps in jumptables
2448 generated for switch statements. For now you need to set the
2449 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2450 Now 4 algorithms for mcs51 jumptable generation are used:
2451 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2452 addresses loaded pc-relative for up to 112 cases and stack-pushing
2453 target addresses loaded with offset from dptr for up to 256 cases.

2485 * added libc directory. The current version of LibC contains string
2486 functions, ctype functions and macros and some functions of the
2487 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2488 be extensively tested in the future. Standard disclaimer here.

2501 * (pic16_storeForReturn): optimized return of 0,
2502 * (genCmp): experimental code for new genCmp which uses PIC18's
2503 special compare&skip instructions. Initial tests fail some times
2504 with variables grater than 1 byte in size, so new code is disabled,
2505 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2507 * (genCast): began a fix to optimize the casting of a bit to another
2508 bit, now assigning a bitfield to another bitfield will fail, sorry,

2522 registers when it shouldn't,
2523 * src/pic16/ralloc.c (allocReg): add preliminary support for
2524 supporting a limited set of temporary registers,
2526 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5531 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5533 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5534 loaded with the linker search paths (-L arguments) and the libraries
5535 to be linked with the current source (-l arguments). Changes
5536 currently will affect only the pic16 port.
5537 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5538 include path the port specific paths and port specific libraries,
5539 * gplink command now contains the $3 argument,
5540 * src/pic16/device.h,
5541 * src/pic16/device.c,: structure PIC_device is made public and
5542 renamed to PIC16_device, the same for variable Pics which is renamed

5557 Documenting changes from previous commits.
5558 * configure.in (version 1.56),
5559 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5560 when generating output files to configure the pic16 library,
5561 but now I've commented it out, since gputils aren't installed in the
5562 SF compile farm, so library won't compile
5564 * device/lib/Makefile.in (version 1.56): initially I've added in
5565 target 'all' the prerequestive 'model-pic16' so it compiled the
5566 pic16 library, but now I've commented it out for the same reasons
5568 * added targets 'model-pic16' and 'objects-pic16' to compile the
5570 * added target 'port-specific-objects-pic16' to handle the
5571 generated libraries and copy them into the build/ directory
5572 * added target 'clean-intermediate-pic16' to clean intermediate
5573 files into pic16 directory
5574 * in target 'installdirs' added line to create directory pic16 in

5595 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5596 option so that it actually works. Made it specific to the z80, since
5597 the gbz80 doesn't have these kinds of I/O ports.
5599 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5601 * device/include/z180.h,

5625 via literal number. The symbol is placed in the corresponding
5626 position of the data ram
5627 * (pic16_dump_section): relocatable and absolute uninitialized
5628 data are now emitted in sorted order to reduce section naming,
5629 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5630 weren't marked as being in the access bank,
5632 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5634 Added portion of GNU PIC Library under the directory
5635 device/include/pic16 and device/lib/pic16. These files
5636 contain the declarations of SFRs for the PIC18Fxx2 devices.
5637 The directory is initialized via configure from toplevel.
5639 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5641 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5667 all over. Telling LaTeX to be less strict with word spacing
5668 to better keep the right margin. Changed some notes about
5669 maintainance of the ports in section 3.2.1 - is it OK like this?
5671 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5673 SDCC source changes:
5674 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
5675 convilong): modified to inform the pic16 port that builtin functions
5678 PIC16 PORT specific changes:
5679 * src/pic16/device.c pic16_dump_equates() added,
5680 processor registers declared internally by the port are emitted in
5681 the translation as equates,
5682 * src/pic16/gen.c: inline code is passed unprocessed to the
5684 * (pic16_popGetLit2): fnuction modified to take second operand as
5685 pCodeOp pointer and not as literal,
5686 * (popRegFromIdx): prefixed with pic16_,

5689 * (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): added
5690 * (genFunction): initializes local stack frame and pushes on stack
5691 all the registers used by this function,
5692 * (genEndFunction): restores all registers from stack and restores
5694 * src/pic16/glue.c (pic16emitRegularMap): various changes and

5708 UPPER for immediate operands,
5709 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5711 * src/pic16/peeph.def: all peepholes with movff are commented out,
5712 because there is a problem in the pcode peep optimizer,

5823 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5825 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5826 (default behaviour).
5828 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5830 A python script to validate compiler diagnostic messages. It can be
5831 used to verify that sdcc complains about bad c source code and
5832 gives a good location of the error.
5833 * support/valdiag/Makefile,
5834 * support/valdiag/valdiag.py,
5835 * support/valdiag/tests/*

5852 Bug reported from Jesus Calvino-Fraga
5854 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5856 * sdcc.spec: updated
5857 * device/include/Makefile.in: don't install CVS directories
5858 * device/lib/Makefile.in: added removal of CVS directories after install
5859 * doc/Makefile: fixed install, added local_icons
5860 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5861 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5862 * src/ds390/gen.c (genRightShift): fixed bug #870788
5863 * src/SDCCast.c (decorateType): fixed bug #870781
5865 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5867 PIC16 port related changes:
5868 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5869 added variable stackPos,
5871 * gen.c: genCall, assignResultValue: added support for
5872 pushing/retrieving function parameters to/from stack,
5873 genFunction,genEndFunction: setup stack frame for the
5875 genAddrOf: will be changed according to bug 863624
5877 * added files genutils.c and genutils.h which contain gen*
5878 debugged and optimised functions extracted from gen.c
5880 * glue.c: added variable 'externs' which holds extern symbols,
5881 pic16emitRegularMap: is modified to properly handle relocatable
5882 symbols under the new scheme,
5883 pic16createInterruptVect: is modified
5884 pic16printPublics: is modified to emit 'global' assembler directives,
5885 added pic16_printExterns to print extern symbols,
5886 pic16glue: initializes stack/frame pointer in the beginning of
5887 the assembly output. Temporary hack, will be corrected later,
5888 because gplink yet does not support stack and SDCC does not
5889 yet support a type of crt0.o object to create the final binary.
5891 * Removed many lines that contain 8051 legacy code.
5892 * The code is finally placed under a 'code' directive.
5893 * Added port specific options.
5895 * _process_pragma: simplified since now we do not need *special*
5896 include file to define SFR registers. But a separate header
5897 will be needed. This will be developed later.
5898 * _pic16_parseOptions: added, parses port specific options:
5899 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5900 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5901 --preplace-udata-with=
5903 * _pic16_setDefaultOptions: modified to initialize section names,
5904 but hack is temporarly out of order since it needs improvement.
5905 * _pic16_genAssemblerPreamble: configuration words are emitted by
5906 their address instead of their name. This part is incomplete and
5907 supports only the 18Fxx2 devices. Other devices will emit an error
5908 during assembly since they do not contain the same set of config
5910 * _pic16_genIVT: is modified,
5912 * pcode.c: added definitions for some hardware registers that are needed
5914 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5915 All PCI entries are updated. Now LFSR is supported.
5916 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5917 * added pic16_newpCodeOpLit2 to support instructions with
5918 two literal arguments
5919 * pic16_pCode2str: corrected code that emits assembler instructions
5920 with two literal operands and those that have an access bit modifier
5921 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5922 this fixes a bug which caused some labels to be lost, when an
5923 assembler directive was added, i.e. banksel,
5924 * pic16_FixRegisterBanking: improved logic that causes the insertion
5926 * InlineFunction: functions that are called once, are not any more
5927 inlined. This can be a port option in the future,
5929 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5931 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5932 hold the corresponding uninitialized symbols,
5933 * pic16_allocProcessorRegister: registers have explicit marked the
5935 * pic16_allocInternalRegister: registers are explicit marked as
5937 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5938 processing list, so bit registers were lost,
5941 * ralloc.h: added field 'accessBank' and original symbol operand
5942 in register definition,
5943 * removed the field isMapped from register definition,
5945 ** Several functions have been removed from various sources:
5946 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5947 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5948 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5949 pic16_assignRelocatableRegisters
5951 ** others have been introduced:
5952 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5953 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5955 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5957 * support/scripts/inc2h.pl: changed definition of BIT_AT
5958 to emit 'sbit at' instead of 'bit at'. This was a request.
5960 PIC16 port related preliminary changes:
5961 * gen.c: prefixed function popRegFromString with
5962 pic16_ and all references to it corrected
5963 * pcode.c: all pic16_pc_* hardware registers prefixed
5964 with underscore (_),
5965 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5966 * ralloc.c: newReg(): when register is REG_SFR then
5967 set address to rIdx,
5968 pic16_allocProcessorRegister(): marks register wasUsed=0
5969 pic16_writeUsedRegs(): added a call to assign processor
5970 registers via pic16_assignFixedRegisters
5972 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5974 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5975 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5976 variables in unused register banks. Also the SSEG is placed
5977 wherever there is enough space for it, and IDATA can be anywhere
5978 in internal RAM. For now compile using -Wl-Y[stack_size].
5979 The mem file is different for this option as well, since it
5980 makes no sense of talking about DSEG lenght.
5982 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5984 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5985 in certain cases, e.g. when ROM assignment, patch provided
5986 from Albert den Haan.
5988 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6991 fetching of the pointer
6992 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6993 copied from genNearPointerSet()
6994 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6995 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7011 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7012 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7013 type for bits was changed. It resulted in bit variables becoming
7014 global, which is not permitted in PIC 14 assembly output.

7031 A few small changes that speed up the peephole optimizer.
7035 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7037 Try to make the peephole optimizer smarter by maintaining
7038 an association between the assembly source code and the
7039 iCodes that originated them. Put this information to use
7040 with a new peephole rule condition "notVolatile" so that
7041 the rules can be aggressive yet still safe.
7046 * src/mcs51/peeph.def
7048 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7052 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7053 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7054 if the left or right operand symbols have the accuse flag set.
7056 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7058 Changed the type of the result of the ! (NOT) operator to char;
7059 previously it returned the same type as the source. This allows
7060 us to eliminate all the genFloatNot functions (all of its target
7061 implementations were very buggy) since !float can use the same

7073 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7074 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7075 during interrupts. Ensure WSAVE is located at a shared bank address.
7076 2. Fixed page selection in some places
7077 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7078 the registers name strings.
7079 4. Fixed "signed / unsigned compare" compiler warnings.
7080 5. The PIC port manages its own allocation of the general purpose
7081 registers, but makes no attempt to reuse them. As a result when
7082 compiling it soon runs out of general purpose registers. Some
7083 additional code was added to the files pcode.c and device.c to walk
7084 through the function call tree and rename the registers so that they
7094 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7101 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7103 Made bitfield a distinct type from bit so that bitfields
7104 convert as per ANSI C and bits retain their traditional
7105 boolean style behaviour. Implemented bitfield support in
7113 * src/ds390/gen.c: bit v bitfield split
7114 * src/z80/gen.c: New support for bitfields
7115 * support/regression/tests/bitfields.c: reenabled z80,
7118 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7120 Rules 246.x, 247.x relate to bitfields, the others speed up
7121 access to xdata mapped I/O devices.
7123 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7125 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7127 Cleaned up genPackBits and genUnpackBits and added two helper
7128 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7129 for literal assignments in genPackBits (thanks to Frieder for
7135 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7137 Fixed bug #748310 (pointer to function type mishandled when the
7138 function name is omitted). Also fixed a SIGSEGV when a function
7139 attribute (reentrant, etc) is used on a non-function or on a
7140 function but misplaced before the parameter list.
7142 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7144 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7169 Made the constant following the "interrupt" keyword optional. If
7170 omitted, the function will not automatically be given an entry
7171 in the interrupt vector table (similar to #pragma NOIV, but
7172 less syntacticly kludgy). The interrupt number is also now
7173 range checked. Also fixed a bug in the high order bit example

7703 added if/endif conditional macros to remove options help
7704 messages from optionsTable when a port is not configured, added
7705 support for the PIc16 port in the ports table, when executing
7706 the compiler with no port specified on command line, a default
7707 port is selected with the new macro DEFAULT_PORT which is
7708 defined in port.h, in setDefaultOptions() linkOptions is removed
7709 from initialization assignment, since now it is a set,
7710 parseCmdLine uses setParseWithComma for linkOptions, in
7711 linkEdit() linkOptions are accessed with new function indexSet()
7712 which returns the i'th item of a set variable. See SDCCset.c, in
7713 linkEdit() when calling buildCmdLine(), added linkOptions as
7714 last argument. Now users can pass arguments to gplink via the
7715 -Wl option, main() uses pic16glue() to glue up pic16 programs

7729 gpasm complaining and test the linkage with gplink, _linkCmd and
7730 _asmCmd changed to be more gplink and gpasm friendly
7731 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7732 produced an error when parsed, peep rule 12 is added to utilize
7733 movff, but it is commented out since the pCode does not support
7734 yet a command with 2 address arguments
7736 2003-05-18 <johan AT balder>
7738 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7763 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7765 2003-05-11 Borut Razem <borut.razem AT siol.net>
7767 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8773 * src/SDCCicode.c: fixed array add
8775 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8776 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8777 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8779 2003-01-04 <johan AT balder>
8781 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8783 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8784 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8786 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8796 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8797 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8799 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8801 * in \sdcc\as\mcs51\ changed these files in order to create an
8802 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8803 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8804 following files to include the previous two files: aslink.dsp,
8805 Makefile.aslink, Makefile.bcc, and Makefile.in.
8807 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8808 .adb instead of .cdb
8810 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8812 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8813 value from option --iram-size.
8815 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8817 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8820 2002-09-18 <wiml AT hhhh.org>
8822 * SDCClrange.h: exposed setFromRange() and setToRange()
8823 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8824 packRegsForAccUse() (bug 542397)
8825 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8826 multiple times and emitting the fetch operations more than once
8827 added aopGetUsesAcc() function to allow binary operators to
8828 fetch their operands in the correct order; made genMinus() emit
8829 compact code for X = LITERAL - Y
8831 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8832 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8833 sprintf() in line 1267.
8835 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8836 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8839 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8840 Changes to aslink (All the changes are marked with 'JCF'):
8842 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8845 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8846 area BSEG. Also moves, if possible, the DATA area down into the internal
8847 ram so more space is available.
8849 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8852 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8853 not bytes. Function summary() which creates a memory usage summary
8854 file with extension .mem. Reports of overlaping stack and small stack
8855 size. If the space for the stack is less than 16 bytes aslink trows a
8858 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8859 the 8051. Option 'y' for memory summary output file.
8861 Changes to sdcc (All the changes are marked with 'JCF'):
8863 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8865 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8866 overlaying area for it (uses RegBankUsed[4]).
8868 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8869 bank zero as used by default. By default aslink locates the stack
8870 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8871 the creation of the .mem file. Delegates the allocation of data area
8872 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8873 the begining of the stack area to aslink.
8875 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8876 glue() in SDCCglue.c creates an area for it.
8878 2002-09-03 Borut Razem <borut.razem AT siol.net>
8879 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8880 sdcc/src/pic/glue.c:
8881 introduced atexit() handler for teporay files removal in case of
8882 errors, assertions, ...
8884 2002-08-29 Borut Razem <borut.razem AT siol.net>
8885 * sdcc/support/cpp2/auto-host_vc_in.h:
8886 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8887 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8888 Maybe there is a similar problem with BORLANDC? It should be checked!
8890 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8891 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8892 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8893 was not executed, and the compiler (cl) launched a warning:
8894 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8896 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8897 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8899 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8900 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8902 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8903 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8904 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8905 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8906 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8907 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8908 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8909 - added Release configuration in VS projects
8910 - review of compiler an linker options
8911 - VC .exe files are generated in bin_vc directory, not to interfere
8912 with binaries generated from other projects (cygwin, mingw, bcc ...)
8914 * sdcc/src/yacc.dsp: added
8916 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8917 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8918 and insert the version number definitions from .version
8920 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8922 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8923 added - genarate auto-host.h using auto-host_vc_in.h as template
8926 removed from CVS, generated automatically
8928 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8929 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8931 2002-08-11 Borut Razem <borut.razem AT siol.net>
8932 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8934 2002-08-10 Borut Razem <borut.razem AT siol.net>
8935 * src/SDCCmain.c (main):
8936 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8937 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8938 The consequence was that some temporary files were not removed.
8941 unification of code in functions tempfilename() and tempfile():
8942 function tempnam() is defined in Visual Studio 6.0 and .NET
8944 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8946 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8947 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8948 - removed compiler command line option /WX: Treats all warnings as errors
8949 - update a list of source files, included into the project
8951 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8952 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8953 changed project type to Generic Project so that can be correcly converted to VS.NET project
8955 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8957 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8959 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8961 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8962 added return 0 statements after assert() to make compiler happy
8964 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8965 added newline in the def file to keep MSC compiler satisfied
8967 * sdcc/src/z80/gen.c:
8968 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8969 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8970 - solved MSC error in function aopDump()
8972 * sdcc_vc.h: define PREFIX as "\\sdcc"
8974 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8975 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8978 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8979 - Rewrote the register banking algorithm.
8980 - Added pCode live-range analysis to registers (for now, only non-used and
8981 singly-used registers optimized away)
8983 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8985 * 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.

9014 2002-03-28 Johan Knol <johan AT balder>
9016 * src/SDCCval.c: fixed bug #532436
9018 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9020 Added "char *Processor" field to the port structure.
9023 Added -p option. Allows port dependent processor to be specified.
9026 Initialized the new field char *Processor field to NULL in all ports
9029 Compiler generated registers for interrupt context saving
9030 were not getting allocated.
9032 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9035 Fixed left shift. Will promote the left side of a left shift
9036 if a) left shifting more than size of operand or b) when assigned
9037 to something size > size of left side
9039 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9041 tons of changes. Register allocation has been
9042 rewritten. Added customization for the various PICs. Flow
9043 analysis is restructured. ...
9049 Added. device.c is a PIC port hack to accomodate variations

9149 * sdcc/src/SDCCloop.c:
9150 Previous fix was not good. basic blocks that have "break" or "return" are
9151 not really partof a loop , but live ranges used in these blocks should
9152 be live thru the entire loop, so set partOfLoop but don't add them to
