1267 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1269 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1270 loaded with the linker search paths (-L arguments) and the libraries
1271 to be linked with the current source (-l arguments). Changes
1272 currently will affect only the pic16 port.
1273 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1274 include path the port specific paths and port specific libraries,
1275 * gplink command now contains the $3 argument,
1276 * src/pic16/device.h,
1277 * src/pic16/device.c,: structure PIC_device is made public and

1293 Documenting changes from previous commits.
1294 * configure.in (version 1.56),
1295 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1296 when generating output files to configure the pic16 library,
1297 but now I've commented it out, since gputils aren't installed in the
1298 SF compile farm, so library won't compile
1300 * device/lib/Makefile.in (version 1.56): initially I've added in
1301 target 'all' the prerequestive 'model-pic16' so it compiled the
1302 pic16 library, but now I've commented it out for the same reasons
1304 * added targets 'model-pic16' and 'objects-pic16' to compile the
1306 * added target 'port-specific-objects-pic16' to handle the
1307 generated libraries and copy them into the build/ directory
1308 * added target 'clean-intermediate-pic16' to clean intermediate
1309 files into pic16 directory
1310 * in target 'installdirs' added line to create directory pic16 in
1311 the installation path

1314 added lines to copy all header files to installation path,
1315 * in target 'installdirs' added line create directory for pic16
1316 headers in the installation path

1332 option so that it actually works. Made it specific to the z80, since
1333 the gbz80 doesn't have these kinds of I/O ports.
1335 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1337 * device/include/z180.h,

1364 data are now emitted in sorted order to reduce section naming,
1365 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1366 weren't marked as being in the access bank,
1368 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1370 Added portion of GNU PIC Library under the directory
1371 device/include/pic16 and device/lib/pic16. These files
1372 contain the declarations of SFRs for the PIC18Fxx2 devices.
1373 The directory is initialized via configure from toplevel.

1444 UPPER for immediate operands,
1445 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1447 * src/pic16/peeph.def: all peepholes with movff are commented out,
1448 because there is a problem in the pcode peep optimizer,
1449 * src/pic16/ralloc.c: the register allocator can now reuse local

1559 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1561 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1562 (default behaviour).
1564 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1566 A python script to validate compiler diagnostic messages. It can be
1567 used to verify that sdcc complains about bad c source code and
1568 gives a good location of the error.
1569 * support/valdiag/Makefile,
1570 * support/valdiag/valdiag.py,
1571 * support/valdiag/tests/*

1588 Bug reported from Jesus Calvino-Fraga
1590 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1592 * sdcc.spec: updated
1593 * device/include/Makefile.in: don't install CVS directories
1594 * device/lib/Makefile.in: added removal of CVS directories after install
1595 * doc/Makefile: fixed install, added local_icons
1596 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1597 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1598 * src/ds390/gen.c (genRightShift): fixed bug #870788
1599 * src/SDCCast.c (decorateType): fixed bug #870781
1601 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1603 PIC16 port related changes:
1604 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1605 added variable stackPos,
1607 * gen.c: genCall, assignResultValue: added support for
1608 pushing/retrieving function parameters to/from stack,
1609 genFunction,genEndFunction: setup stack frame for the
1611 genAddrOf: will be changed according to bug 863624
1613 * added files genutils.c and genutils.h which contain gen*
1614 debugged and optimised functions extracted from gen.c
1616 * glue.c: added variable 'externs' which holds extern symbols,
1617 pic16emitRegularMap: is modified to properly handle relocatable
1618 symbols under the new scheme,
1619 pic16createInterruptVect: is modified
1620 pic16printPublics: is modified to emit 'global' assembler directives,
1621 added pic16_printExterns to print extern symbols,
1622 pic16glue: initializes stack/frame pointer in the beginning of
1623 the assembly output. Temporary hack, will be corrected later,
1624 because gplink yet does not support stack and SDCC does not
1625 yet support a type of crt0.o object to create the final binary.
1627 * Removed many lines that contain 8051 legacy code.
1628 * The code is finally placed under a 'code' directive.
1629 * Added port specific options.
1631 * _process_pragma: simplified since now we do not need *special*
1632 include file to define SFR registers. But a separate header
1633 will be needed. This will be developed later.
1634 * _pic16_parseOptions: added, parses port specific options:
1635 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1636 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1637 --preplace-udata-with=
1639 * _pic16_setDefaultOptions: modified to initialize section names,
1640 but hack is temporarly out of order since it needs improvement.
1641 * _pic16_genAssemblerPreamble: configuration words are emitted by
1642 their address instead of their name. This part is incomplete and
1643 supports only the 18Fxx2 devices. Other devices will emit an error
1644 during assembly since they do not contain the same set of config
1646 * _pic16_genIVT: is modified,
1648 * pcode.c: added definitions for some hardware registers that are needed
1650 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1651 All PCI entries are updated. Now LFSR is supported.
1652 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1653 * added pic16_newpCodeOpLit2 to support instructions with
1654 two literal arguments
1655 * pic16_pCode2str: corrected code that emits assembler instructions
1656 with two literal operands and those that have an access bit modifier
1657 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1658 this fixes a bug which caused some labels to be lost, when an
1659 assembler directive was added, i.e. banksel,
1660 * pic16_FixRegisterBanking: improved logic that causes the insertion
1662 * InlineFunction: functions that are called once, are not any more
1663 inlined. This can be a port option in the future,
1665 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1667 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1668 hold the corresponding uninitialized symbols,
1669 * pic16_allocProcessorRegister: registers have explicit marked the
1671 * pic16_allocInternalRegister: registers are explicit marked as
1673 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1674 processing list, so bit registers were lost,
1677 * ralloc.h: added field 'accessBank' and original symbol operand
1678 in register definition,
1679 * removed the field isMapped from register definition,
1681 ** Several functions have been removed from various sources:
1682 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1683 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1684 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1685 pic16_assignRelocatableRegisters
1687 ** others have been introduced:
1688 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1689 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1691 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1693 * support/scripts/inc2h.pl: changed definition of BIT_AT
1694 to emit 'sbit at' instead of 'bit at'. This was a request.
1696 PIC16 port related preliminary changes:
1697 * gen.c: prefixed function popRegFromString with
1698 pic16_ and all references to it corrected
1699 * pcode.c: all pic16_pc_* hardware registers prefixed
1700 with underscore (_),
1701 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1702 * ralloc.c: newReg(): when register is REG_SFR then
1703 set address to rIdx,
1704 pic16_allocProcessorRegister(): marks register wasUsed=0
1705 pic16_writeUsedRegs(): added a call to assign processor
1706 registers via pic16_assignFixedRegisters
1708 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1710 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1711 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1712 variables in unused register banks. Also the SSEG is placed
1713 wherever there is enough space for it, and IDATA can be anywhere
1714 in internal RAM. For now compile using -Wl-Y[stack_size].
1715 The mem file is different for this option as well, since it
1716 makes no sense of talking about DSEG lenght.
1718 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1720 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1721 in certain cases, e.g. when ROM assignment, patch provided
1722 from Albert den Haan.
1724 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

1867 * src/mcs51/peephole.def,
1868 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
1869 (allows non-interrupt and interrupt code to safely compete for a resource

2609 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
2610 support for standard C idiom of memory mapped variables; for
2611 example, *((xdata int*)0x1234) = 1 is now internally equivalent
2612 to xdata int at 0x1234 tempvar = 1.
2613 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
2614 provided by Akiya ISHIDA

2630 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2632 Fixed bug #621531 (const & volatile confusion in the type chain).
2633 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
2634 refer to the const or volatile state of the pointer itself.

2699 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
2700 pcoderegs.h, ralloc.c, ralloc.h
2701 * main.c: added top header and GPL license notice

2717 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
2719 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
2720 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
2721 before instructions that use the _STATUS register
2723 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
2725 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
2726 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
2727 fetching of the pointer
2728 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
2729 copied from genNearPointerSet()
2730 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
2731 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
2732 If they pop r0/r1 they must be called in the opposite order than aopOp().
2733 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
2734 (resp. --stack-auto), prepared for --xstack

2743 these ports have their own __sdcc_external_start()
2745 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
2747 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2748 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
2749 type for bits was changed. It resulted in bit variables becoming
2750 global, which is not permitted in PIC 14 assembly output.
2752 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2754 * doc/sdccman.lyx: various additions and updates. Rearranged sections
2756 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2758 Z80 and MCS51 linkers complaint if a public symbol is defined
2759 in more than one library module:
2763 * as/mcs51/Makefile.in
2765 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2767 A few small changes that speed up the peephole optimizer.
2771 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2773 Try to make the peephole optimizer smarter by maintaining
2774 an association between the assembly source code and the
2775 iCodes that originated them. Put this information to use
2776 with a new peephole rule condition "notVolatile" so that
2777 the rules can be aggressive yet still safe.
2782 * src/mcs51/peeph.def
2784 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2788 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2789 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2790 if the left or right operand symbols have the accuse flag set.
2792 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2794 Changed the type of the result of the ! (NOT) operator to char;
2795 previously it returned the same type as the source. This allows
2796 us to eliminate all the genFloatNot functions (all of its target
2797 implementations were very buggy) since !float can use the same
2800 * src/SDCCicode.c (ast2iCode): ! returns char
2801 * src/mcs51/gen.c (genNot, genNotFloat),
2802 * src/ds390/gen.c (genNot, genNotFloat),
2803 * src/z80/gen.c (genNot, genNotFloat),
2804 * src/pic/gen.c (genNot, genNotFloat),
2805 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
2807 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
2809 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2810 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2811 during interrupts. Ensure WSAVE is located at a shared bank address.
2812 2. Fixed page selection in some places
2813 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2814 the registers name strings.
2815 4. Fixed "signed / unsigned compare" compiler warnings.
2816 5. The PIC port manages its own allocation of the general purpose
2817 registers, but makes no attempt to reuse them. As a result when
2818 compiling it soon runs out of general purpose registers. Some
2819 additional code was added to the files pcode.c and device.c to walk
2820 through the function call tree and rename the registers so that they
2830 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2831 genPlus() & genMinus() when the result is the same as left or right
2833 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2837 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2839 Made bitfield a distinct type from bit so that bitfields
2840 convert as per ANSI C and bits retain their traditional
2841 boolean style behaviour. Implemented bitfield support in
2849 * src/ds390/gen.c: bit v bitfield split
2850 * src/z80/gen.c: New support for bitfields
2851 * support/regression/tests/bitfields.c: reenabled z80,
2854 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2856 Rules 246.x, 247.x relate to bitfields, the others speed up
2857 access to xdata mapped I/O devices.
2859 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2861 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2863 Cleaned up genPackBits and genUnpackBits and added two helper
2864 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2865 for literal assignments in genPackBits (thanks to Frieder for
2871 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2873 Fixed bug #748310 (pointer to function type mishandled when the
2874 function name is omitted). Also fixed a SIGSEGV when a function
2875 attribute (reentrant, etc) is used on a non-function or on a
2876 function but misplaced before the parameter list.
2878 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
2880 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
2881 * support/Util/SDCCerr.h,
2882 * support/Util/SDCCerr.c: Added func attr misuse error msg
2884 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
2886 Fixed bug #787649 by anonymous
2887 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
2888 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
2890 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2892 Fixed numerous bitfield problems.

2900 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
2901 * support/regression/tests/bitfields.c: tests added
2903 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2905 Made the constant following the "interrupt" keyword optional. If
2906 omitted, the function will not automatically be given an entry
2907 in the interrupt vector table (similar to #pragma NOIV, but
2908 less syntacticly kludgy). The interrupt number is also now
2909 range checked. Also fixed a bug in the high order bit example
2916 * support/Util/SDCCerr.c
2917 * support/Util/SDCCerr.h
2920 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
2922 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
2923 * src/SDCCicode.c (operandOperation): rewritten some ops
2924 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
2925 * src/SDCCsymt.c (computeType): literals are handled the same way as any
2927 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can

3385 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3386 the regression tests I'm not brave enough to enable 245.b, 245.c
3387 * doc/sdccman.lyx: added latex preamble for hyperref package.
3388 Using pdflatex this will give you a hyperlinked pdf file with
3389 bookmarks. (prepend '%' before /usepackage if this breaks something)

3438 * src/SDCCmain.c: linkOptions is changed to set *,
3439 added if/endif conditional macros to remove options help
3440 messages from optionsTable when a port is not configured, added
3441 support for the PIc16 port in the ports table, when executing
3442 the compiler with no port specified on command line, a default
3443 port is selected with the new macro DEFAULT_PORT which is
3444 defined in port.h, in setDefaultOptions() linkOptions is removed
3445 from initialization assignment, since now it is a set,
3446 parseCmdLine uses setParseWithComma for linkOptions, in
3447 linkEdit() linkOptions are accessed with new function indexSet()
3448 which returns the i'th item of a set variable. See SDCCset.c, in
3449 linkEdit() when calling buildCmdLine(), added linkOptions as
3450 last argument. Now users can pass arguments to gplink via the
3451 -Wl option, main() uses pic16glue() to glue up pic16 programs

3464 * src/pic16/main.c: __config directives are commented out to stop
3465 gpasm complaining and test the linkage with gplink, _linkCmd and
3466 _asmCmd changed to be more gplink and gpasm friendly
3467 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3468 produced an error when parsed, peep rule 12 is added to utilize
3469 movff, but it is commented out since the pCode does not support
3470 yet a command with 2 address arguments
3472 2003-05-18 <johan AT balder>
3474 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4509 * src/SDCCicode.c: fixed array add
4511 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
4512 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
4513 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4515 2003-01-04 <johan AT balder>
4517 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4519 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4520 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
4522 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
4523 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

4529 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
4530 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
4532 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4533 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4535 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4537 * in \sdcc\as\mcs51\ changed these files in order to create an
4538 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4539 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4540 following files to include the previous two files: aslink.dsp,
4541 Makefile.aslink, Makefile.bcc, and Makefile.in.
4543 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4544 .adb instead of .cdb
4546 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4548 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4549 value from option --iram-size.
4551 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4553 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4556 2002-09-18 <wiml AT hhhh.org>
4558 * SDCClrange.h: exposed setFromRange() and setToRange()
4559 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4560 packRegsForAccUse() (bug 542397)
4561 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4562 multiple times and emitting the fetch operations more than once
4563 added aopGetUsesAcc() function to allow binary operators to
4564 fetch their operands in the correct order; made genMinus() emit
4565 compact code for X = LITERAL - Y
4567 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4568 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4569 sprintf() in line 1267.
4571 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4572 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4575 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4576 Changes to aslink (All the changes are marked with 'JCF'):
4578 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4581 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4582 area BSEG. Also moves, if possible, the DATA area down into the internal
4583 ram so more space is available.
4585 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4588 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4589 not bytes. Function summary() which creates a memory usage summary
4590 file with extension .mem. Reports of overlaping stack and small stack
4591 size. If the space for the stack is less than 16 bytes aslink trows a
4594 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4595 the 8051. Option 'y' for memory summary output file.
4597 Changes to sdcc (All the changes are marked with 'JCF'):
4599 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4601 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4602 overlaying area for it (uses RegBankUsed[4]).
4604 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4605 bank zero as used by default. By default aslink locates the stack
4606 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4607 the creation of the .mem file. Delegates the allocation of data area
4608 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4609 the begining of the stack area to aslink.
4611 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4612 glue() in SDCCglue.c creates an area for it.
4614 2002-09-03 Borut Razem <borut.razem AT siol.net>
4615 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4616 sdcc/src/pic/glue.c:
4617 introduced atexit() handler for teporay files removal in case of
4618 errors, assertions, ...
4620 2002-08-29 Borut Razem <borut.razem AT siol.net>
4621 * sdcc/support/cpp2/auto-host_vc_in.h:
4622 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4623 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4624 Maybe there is a similar problem with BORLANDC? It should be checked!
4626 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4627 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4628 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4629 was not executed, and the compiler (cl) launched a warning:
4630 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4632 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4633 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4635 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4636 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4638 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4639 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4640 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4641 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4642 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4643 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4644 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4645 - added Release configuration in VS projects
4646 - review of compiler an linker options
4647 - VC .exe files are generated in bin_vc directory, not to interfere
4648 with binaries generated from other projects (cygwin, mingw, bcc ...)
4650 * sdcc/src/yacc.dsp: added
4652 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4653 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4654 and insert the version number definitions from .version
4656 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4658 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4659 added - genarate auto-host.h using auto-host_vc_in.h as template
4662 removed from CVS, generated automatically
4664 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4665 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4667 2002-08-11 Borut Razem <borut.razem AT siol.net>
4668 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4670 2002-08-10 Borut Razem <borut.razem AT siol.net>
4671 * src/SDCCmain.c (main):
4672 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4673 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4674 The consequence was that some temporary files were not removed.
4677 unification of code in functions tempfilename() and tempfile():
4678 function tempnam() is defined in Visual Studio 6.0 and .NET
4680 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4682 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4683 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4684 - removed compiler command line option /WX: Treats all warnings as errors
4685 - update a list of source files, included into the project
4687 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4688 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4689 changed project type to Generic Project so that can be correcly converted to VS.NET project
4691 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4693 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4695 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
4697 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4698 added return 0 statements after assert() to make compiler happy
4700 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4701 added newline in the def file to keep MSC compiler satisfied
4703 * sdcc/src/z80/gen.c:
4704 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4705 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4706 - solved MSC error in function aopDump()
4708 * sdcc_vc.h: define PREFIX as "\\sdcc"
4710 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
4711 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

4750 2002-03-28 Johan Knol <johan AT balder>
4752 * src/SDCCval.c: fixed bug #532436
4754 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4756 Added "char *Processor" field to the port structure.
4759 Added -p option. Allows port dependent processor to be specified.
4762 Initialized the new field char *Processor field to NULL in all ports
4765 Compiler generated registers for interrupt context saving
4766 were not getting allocated.
4768 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4771 Fixed left shift. Will promote the left side of a left shift
4772 if a) left shifting more than size of operand or b) when assigned
4773 to something size > size of left side
4775 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4777 tons of changes. Register allocation has been
4778 rewritten. Added customization for the various PICs. Flow
4779 analysis is restructured. ...
4785 Added. device.c is a PIC port hack to accomodate variations
4788 2002-03-13 Michael Hope <michaelh AT vroom>
4790 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
4792 2002-03-04 johanknol <johanknol AT manik>

4801 * /device/include/mcs51reg.h:
4802 ds89c420 register definition update
4804 2002-03-03 <johan AT FRIJA>
