1345 on rIfx (genCmp was broken)
1347 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1349 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1350 * src/z80/main.c (_keywords[]),
1351 * src/SDCCglobal.h (struct options),
1353 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1354 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1355 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1356 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1357 always available in leading double underscore form. The C99 support is
1358 mostly missing, but it's a start.
1359 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1360 reserved identifier "__data".
1362 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1364 * src/mcs51/peeph.def: fixed bug 1170013

1406 immedDom() returning wrong block; probably fixes bug #1160833)
1408 2005-03-20 Borut Razem <borut.razem AT siol.net>
1410 * support/scripts/inc2h.pl: WIN32 port

1414 * device/lib/makefile.in: added abs.c and labs.c
1416 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1418 * device/include/stdint.h: added
1419 * device/lib/abs.c: added

1438 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1440 * device/lib/printf_large.c: removed inline assembly for portability and
1441 readability. Use printf_fast if speed or size are more important.
1442 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1443 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1445 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1447 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1448 prevent compiler warning
1450 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1452 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1453 moved to level 0 and declared as static. Also they are explicit
1454 placed in access bank. This was necessery because some times they
1455 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1456 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1457 optimizations. Currently only compare to unsigned char is implemented,
1458 * src/pic16/gen.c: added fReturnIdx array,
1459 * (struct resolvedIfx) is moved to gen.h and made public,
1460 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1461 * (aopForSym): added an optimization to directly store in stack of
1462 the operand of a SEND iCode,
1463 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1464 but as registers instead (AOP_REG) using the fReturnIdx array,
1465 * (pic16_freeAsmop): remove the freed register from the
1466 _G.sregsAlloc field,
1467 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1468 a compare of 'WREG',
1469 * (pic16_popGetTempRegCond): changed function prototype, now
1470 function takes also a bitVector argument v which holds the current
1471 set of registers that are allocated for stack access by aopForSym,
1472 registers allocated in aopForSym for accessing stack symbols are not
1473 any more part of the functions usedRegs field,
1474 * (genCall): some times aopOp is called for a stack variable to be
1475 send, aopForSym might perform the push, if this is true make sure
1476 that genCall doesn't push the variable twice by testing _G.resDirect,
1477 * (genFunction): changed testing for unspecified interrupt number
1478 from 256 to INTNO_UNSPEC,
1479 * modified selection scheme of frame pointer generation. Previously
1480 if function did use local registers a frame pointer was generated,
1481 now a frame pointer is generated only if function has arguments
1482 (that need PLUSW2 register access), or has stack arguments, or the
1483 compiler is not instructed to omit the frame pointer,
1484 * (genEndFunction): before restoring local registers that were saved
1485 in the function preamble, also restore the registers that *might*
1486 have been allocated for stack access,
1487 * (genRet): removed some old comments,
1488 * (genCmp, the active (RN's) version): added a call to the
1489 pic16_genCmp_special function to perform the compare with a more
1490 robust and optimized way,
1491 * (genInline): a feature has been added in inline code generation,
1492 which allows a wildcard variable substitution when writing inline
1493 assembly. Code is incomplete and experimental therefore undocumented,
1494 * (genCast): changed order of aopOp for result and right to allow
1495 aopForSym to directly load the result if possible,
1496 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1497 perform an optimized compare on some selected special occasions,
1498 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1499 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1500 generate an IVT any more,
1501 * src/pic16/main.c (pic16_optionsTable): added command line option
1503 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1504 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1506 * src/pic16/NOTES: Raphael Neider added in list of active developers
1507 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1508 jumptable_end to prevent bug #,
1509 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1510 inCond and outCond fields,
1511 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1512 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1513 turn off register spilling,
1514 * (packRegsForOneUse): synced with other ports' versions although it
1515 is not used currently,
1516 * (pic16_packRegisters): added an optimization while reading
1517 structure bitfields, some registers may be saved (malloc code is
1518 decreased by 80 bytes)
1520 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1522 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1523 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1524 this can be optimized more?
1526 2005-03-10 Raphael Neider <rneider AT web.de>
1528 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1529 genNearPointerGet): (hopefully) fixed access to bitfields via
1530 pointers (p->bitN = x; and x = p->bitN; failed)
1532 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1534 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1575 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1576 to keep the correct label reference count when adding/removing references
1577 to labels. A peephole file using this is appended to patch #1144962.

1709 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1710 (sizeof(sectNames) changed to sizeof(sectName))
1711 Both patches fix segfaults under MinGW.
1713 2005-01-23 Raphael Neider <rneider AT web.de>

1716 Safe_[mc]?alloc()'ed variables
1717 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1718 of (byte sized) temporaries (assign them to WREG for now)
1719 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1720 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1721 this might fix SIGSEGVs on MinGW...
1722 * src/SDCCopt.c (killDeadCode): restored original behaviour
1723 (volatile operands might get thrown away though)
1725 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1727 * src/pic16/gen.c: fixed bug #1106975,

1732 * added function attribute 'shadowregs' to take advantage of shadow
1734 * added function attribute 'wparam' as an alternative to the wparam
1736 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
1737 user declares a non-ISR function as 'shadowregs',
1738 * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

2194 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2196 Large cummulative patch for pic16 port.
2197 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2198 to call when a stack overflow occurs,
2199 * (malloc.h): added CVS Id tag,
2200 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2202 * added libc directory. The current version of LibC contains string
2203 functions, ctype functions and macros and some functions of the
2204 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2205 be extensively tested in the future. Standard disclaimer here.
2206 Library is not automatically build yet. But one can build it by
2207 invoking 'make' inside the libc directory.
2208 * added ADC library under libio. Preliminary version yet.
2210 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2218 * (pic16_storeForReturn): optimized return of 0,
2219 * (genCmp): experimental code for new genCmp which uses PIC18's
2220 special compare&skip instructions. Initial tests fail some times
2221 with variables grater than 1 byte in size, so new code is disabled,
2222 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2224 * (genCast): began a fix to optimize the casting of a bit to another
2225 bit, now assigning a bitfield to another bitfield will fail, sorry,
2226 * src/pic16/main.c: disabled the use of lr-support feature,
2227 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2228 * added some function prototypes, added function _debugf prototype,

2230 bits with offset (case PO_GPR_BIT),
2231 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2233 * (isBankInstruction): modified to return 0 for no banking instruction,
2234 and 1 for banking instruction,
2235 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2236 caused stop processing pCodes after a inline assembly block,
2237 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2238 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2239 registers when it shouldn't,
2240 * src/pic16/ralloc.c (allocReg): add preliminary support for
2241 supporting a limited set of temporary registers,
2243 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2245 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2246 genDataPointerSet): ensure assignments always copy in MSB to LSB
2248 (loadRegFromAop): recognize CLRH optimization,
2249 (genFunction): optimize RECEIVE iCodes in reentrant functions
2251 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2253 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2254 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

5251 loaded with the linker search paths (-L arguments) and the libraries
5252 to be linked with the current source (-l arguments). Changes
5253 currently will affect only the pic16 port.
5254 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5255 include path the port specific paths and port specific libraries,
5256 * gplink command now contains the $3 argument,
5257 * src/pic16/device.h,

5275 * configure.in (version 1.56),
5276 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5277 when generating output files to configure the pic16 library,
5278 but now I've commented it out, since gputils aren't installed in the
5279 SF compile farm, so library won't compile
5281 * device/lib/Makefile.in (version 1.56): initially I've added in
5282 target 'all' the prerequestive 'model-pic16' so it compiled the
5283 pic16 library, but now I've commented it out for the same reasons
5285 * added targets 'model-pic16' and 'objects-pic16' to compile the
5287 * added target 'port-specific-objects-pic16' to handle the
5288 generated libraries and copy them into the build/ directory
5289 * added target 'clean-intermediate-pic16' to clean intermediate
5290 files into pic16 directory
5291 * in target 'installdirs' added line to create directory pic16 in
5292 the installation path
5294 * device/include/Makefile.in (version 1.11): in target 'install'
5295 added lines to copy all header files to installation path,
5296 * in target 'installdirs' added line create directory for pic16
5297 headers in the installation path
5299 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5312 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5313 option so that it actually works. Made it specific to the z80, since
5314 the gbz80 doesn't have these kinds of I/O ports.
5316 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5318 * device/include/z180.h,

5324 * device/lib/_strcmp.c,
5325 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5326 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5327 portmode; added deprecation warning for bank= and protmode= forms.
5328 Also, guard against buffer overflow.
5329 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5331 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5333 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5334 changed interrupt vector table generation to only emit declared vectors.

5336 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5338 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5340 Mainly changes to support compilation of the device libraries
5341 * src/pic16/device.c: stack is allocated via symbol and not
5342 via literal number. The symbol is placed in the corresponding
5343 position of the data ram
5344 * (pic16_dump_section): relocatable and absolute uninitialized
5345 data are now emitted in sorted order to reduce section naming,
5346 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5347 weren't marked as being in the access bank,
5349 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5351 Added portion of GNU PIC Library under the directory
5352 device/include/pic16 and device/lib/pic16. These files
5353 contain the declarations of SFRs for the PIC18Fxx2 devices.
5354 The directory is initialized via configure from toplevel.
5356 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5358 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5359 the spilllocations to be compared correctly

5383 * doc/sdccman.lyx: Moved and added some sections, small changes
5384 all over. Telling LaTeX to be less strict with word spacing
5385 to better keep the right margin. Changed some notes about
5386 maintainance of the ports in section 3.2.1 - is it OK like this?
5388 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5425 UPPER for immediate operands,
5426 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5428 * src/pic16/peeph.def: all peepholes with movff are commented out,
5429 because there is a problem in the pcode peep optimizer,
5430 * src/pic16/ralloc.c: the register allocator can now reuse local
5431 function symbols for another function. This saves register usage.
5432 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5434 Added file src/pic16/NOTES with information about program writing on
5435 the current port version.

5540 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5542 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5543 (default behaviour).
5545 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5547 A python script to validate compiler diagnostic messages. It can be
5548 used to verify that sdcc complains about bad c source code and
5549 gives a good location of the error.
5550 * support/valdiag/Makefile,
5551 * support/valdiag/valdiag.py,
5552 * support/valdiag/tests/*

5569 Bug reported from Jesus Calvino-Fraga
5571 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5573 * sdcc.spec: updated
5574 * device/include/Makefile.in: don't install CVS directories
5575 * device/lib/Makefile.in: added removal of CVS directories after install
5576 * doc/Makefile: fixed install, added local_icons
5577 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5578 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5579 * src/ds390/gen.c (genRightShift): fixed bug #870788
5580 * src/SDCCast.c (decorateType): fixed bug #870781
5582 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5584 PIC16 port related changes:
5585 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5586 added variable stackPos,
5588 * gen.c: genCall, assignResultValue: added support for
5589 pushing/retrieving function parameters to/from stack,
5590 genFunction,genEndFunction: setup stack frame for the
5592 genAddrOf: will be changed according to bug 863624
5594 * added files genutils.c and genutils.h which contain gen*
5595 debugged and optimised functions extracted from gen.c
5597 * glue.c: added variable 'externs' which holds extern symbols,
5598 pic16emitRegularMap: is modified to properly handle relocatable
5599 symbols under the new scheme,
5600 pic16createInterruptVect: is modified
5601 pic16printPublics: is modified to emit 'global' assembler directives,
5602 added pic16_printExterns to print extern symbols,
5603 pic16glue: initializes stack/frame pointer in the beginning of
5604 the assembly output. Temporary hack, will be corrected later,
5605 because gplink yet does not support stack and SDCC does not
5606 yet support a type of crt0.o object to create the final binary.
5608 * Removed many lines that contain 8051 legacy code.
5609 * The code is finally placed under a 'code' directive.
5610 * Added port specific options.
5612 * _process_pragma: simplified since now we do not need *special*
5613 include file to define SFR registers. But a separate header
5614 will be needed. This will be developed later.
5615 * _pic16_parseOptions: added, parses port specific options:
5616 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5617 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5618 --preplace-udata-with=
5620 * _pic16_setDefaultOptions: modified to initialize section names,
5621 but hack is temporarly out of order since it needs improvement.
5622 * _pic16_genAssemblerPreamble: configuration words are emitted by
5623 their address instead of their name. This part is incomplete and
5624 supports only the 18Fxx2 devices. Other devices will emit an error
5625 during assembly since they do not contain the same set of config
5627 * _pic16_genIVT: is modified,
5629 * pcode.c: added definitions for some hardware registers that are needed
5631 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5632 All PCI entries are updated. Now LFSR is supported.
5633 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5634 * added pic16_newpCodeOpLit2 to support instructions with
5635 two literal arguments
5636 * pic16_pCode2str: corrected code that emits assembler instructions
5637 with two literal operands and those that have an access bit modifier
5638 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5639 this fixes a bug which caused some labels to be lost, when an
5640 assembler directive was added, i.e. banksel,
5641 * pic16_FixRegisterBanking: improved logic that causes the insertion
5643 * InlineFunction: functions that are called once, are not any more
5644 inlined. This can be a port option in the future,
5646 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5648 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5649 hold the corresponding uninitialized symbols,
5650 * pic16_allocProcessorRegister: registers have explicit marked the
5652 * pic16_allocInternalRegister: registers are explicit marked as
5654 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5655 processing list, so bit registers were lost,
5658 * ralloc.h: added field 'accessBank' and original symbol operand
5659 in register definition,
5660 * removed the field isMapped from register definition,
5662 ** Several functions have been removed from various sources:
5663 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5664 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5665 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5666 pic16_assignRelocatableRegisters
5668 ** others have been introduced:
5669 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5670 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5672 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5674 * support/scripts/inc2h.pl: changed definition of BIT_AT
5675 to emit 'sbit at' instead of 'bit at'. This was a request.
5677 PIC16 port related preliminary changes:
5678 * gen.c: prefixed function popRegFromString with
5679 pic16_ and all references to it corrected
5680 * pcode.c: all pic16_pc_* hardware registers prefixed
5681 with underscore (_),
5682 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5683 * ralloc.c: newReg(): when register is REG_SFR then
5684 set address to rIdx,
5685 pic16_allocProcessorRegister(): marks register wasUsed=0
5686 pic16_writeUsedRegs(): added a call to assign processor
5687 registers via pic16_assignFixedRegisters
5689 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5691 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5692 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5693 variables in unused register banks. Also the SSEG is placed
5694 wherever there is enough space for it, and IDATA can be anywhere
5695 in internal RAM. For now compile using -Wl-Y[stack_size].
5696 The mem file is different for this option as well, since it
5697 makes no sense of talking about DSEG lenght.
5699 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5701 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5702 in certain cases, e.g. when ROM assignment, patch provided
5703 from Albert den Haan.
5705 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6258 not occur if the control variable is involved with a
6259 relational operator.

6748 A few small changes that speed up the peephole optimizer.
6752 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6754 Try to make the peephole optimizer smarter by maintaining
6755 an association between the assembly source code and the
6756 iCodes that originated them. Put this information to use
6757 with a new peephole rule condition "notVolatile" so that
6758 the rules can be aggressive yet still safe.

6770 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6771 if the left or right operand symbols have the accuse flag set.
6773 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6775 Changed the type of the result of the ! (NOT) operator to char;
6776 previously it returned the same type as the source. This allows
6777 us to eliminate all the genFloatNot functions (all of its target
6778 implementations were very buggy) since !float can use the same
6781 * src/SDCCicode.c (ast2iCode): ! returns char

6790 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6791 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6792 during interrupts. Ensure WSAVE is located at a shared bank address.
6793 2. Fixed page selection in some places
6794 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6795 the registers name strings.
6796 4. Fixed "signed / unsigned compare" compiler warnings.
6797 5. The PIC port manages its own allocation of the general purpose
6798 registers, but makes no attempt to reuse them. As a result when
6799 compiling it soon runs out of general purpose registers. Some
6800 additional code was added to the files pcode.c and device.c to walk
6801 through the function call tree and rename the registers so that they
6811 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6812 genPlus() & genMinus() when the result is the same as left or right

6818 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6820 Made bitfield a distinct type from bit so that bitfields
6821 convert as per ANSI C and bits retain their traditional
6822 boolean style behaviour. Implemented bitfield support in
6830 * src/ds390/gen.c: bit v bitfield split
6831 * src/z80/gen.c: New support for bitfields
6832 * support/regression/tests/bitfields.c: reenabled z80,
6835 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6837 Rules 246.x, 247.x relate to bitfields, the others speed up
6838 access to xdata mapped I/O devices.
6840 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6842 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6844 Cleaned up genPackBits and genUnpackBits and added two helper
6845 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6846 for literal assignments in genPackBits (thanks to Frieder for
6852 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6854 Fixed bug #748310 (pointer to function type mishandled when the
6855 function name is omitted). Also fixed a SIGSEGV when a function
6856 attribute (reentrant, etc) is used on a non-function or on a
6857 function but misplaced before the parameter list.

6884 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6886 Made the constant following the "interrupt" keyword optional. If
6887 omitted, the function will not automatically be given an entry
6888 in the interrupt vector table (similar to #pragma NOIV, but
6889 less syntacticly kludgy). The interrupt number is also now
6890 range checked. Also fixed a bug in the high order bit example

7359 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7360 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7361 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

7366 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7367 the regression tests I'm not brave enough to enable 245.b, 245.c
7368 * doc/sdccman.lyx: added latex preamble for hyperref package.
7369 Using pdflatex this will give you a hyperlinked pdf file with
7370 bookmarks. (prepend '%' before /usepackage if this breaks something)

7411 it can be defined with CFLAGS when running configure
7412 * src/SDCCmain.c: fixed compiling + linking with object files
7414 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7417 added --disable-pic16-port
7418 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7419 * src/SDCCmain.c: linkOptions is changed to set *,
7420 added if/endif conditional macros to remove options help
7421 messages from optionsTable when a port is not configured, added
7422 support for the PIc16 port in the ports table, when executing
7423 the compiler with no port specified on command line, a default
7424 port is selected with the new macro DEFAULT_PORT which is
7425 defined in port.h, in setDefaultOptions() linkOptions is removed
7426 from initialization assignment, since now it is a set,
7427 parseCmdLine uses setParseWithComma for linkOptions, in
7428 linkEdit() linkOptions are accessed with new function indexSet()
7429 which returns the i'th item of a set variable. See SDCCset.c, in
7430 linkEdit() when calling buildCmdLine(), added linkOptions as
7431 last argument. Now users can pass arguments to gplink via the
7432 -Wl option, main() uses pic16glue() to glue up pic16 programs
7433 * src/SDCCpeeph.c: various changes to support pic16

7444 * src/pic16/glue.c: commented out some error producing lines
7445 * src/pic16/main.c: __config directives are commented out to stop
7446 gpasm complaining and test the linkage with gplink, _linkCmd and
7447 _asmCmd changed to be more gplink and gpasm friendly
7448 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7449 produced an error when parsed, peep rule 12 is added to utilize
7450 movff, but it is commented out since the pCode does not support
7451 yet a command with 2 address arguments
7453 2003-05-18 <johan AT balder>
7455 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7480 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7482 2003-05-11 Borut Razem <borut.razem AT siol.net>
7484 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7485 the path of bin directory, so that PATH is the only env. variable, which has to be set
7486 in case of standard installation.
7487 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8490 * src/SDCCicode.c: fixed array add
8492 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8493 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8494 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8496 2003-01-04 <johan AT balder>
8498 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8500 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8501 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8513 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8514 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8516 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8518 * in \sdcc\as\mcs51\ changed these files in order to create an
8519 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8520 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8521 following files to include the previous two files: aslink.dsp,
8522 Makefile.aslink, Makefile.bcc, and Makefile.in.
8524 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8525 .adb instead of .cdb
8527 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8529 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8530 value from option --iram-size.
8532 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8534 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8537 2002-09-18 <wiml AT hhhh.org>
8539 * SDCClrange.h: exposed setFromRange() and setToRange()
8540 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8541 packRegsForAccUse() (bug 542397)
8542 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8543 multiple times and emitting the fetch operations more than once
8544 added aopGetUsesAcc() function to allow binary operators to
8545 fetch their operands in the correct order; made genMinus() emit
8546 compact code for X = LITERAL - Y
8548 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8549 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8550 sprintf() in line 1267.
8552 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8553 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8556 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8557 Changes to aslink (All the changes are marked with 'JCF'):
8559 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8562 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8563 area BSEG. Also moves, if possible, the DATA area down into the internal
8564 ram so more space is available.
8566 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8569 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8570 not bytes. Function summary() which creates a memory usage summary
8571 file with extension .mem. Reports of overlaping stack and small stack
8572 size. If the space for the stack is less than 16 bytes aslink trows a
8575 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8576 the 8051. Option 'y' for memory summary output file.
8578 Changes to sdcc (All the changes are marked with 'JCF'):
8580 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8582 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8583 overlaying area for it (uses RegBankUsed[4]).
8585 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8586 bank zero as used by default. By default aslink locates the stack
8587 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8588 the creation of the .mem file. Delegates the allocation of data area
8589 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8590 the begining of the stack area to aslink.
8592 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8593 glue() in SDCCglue.c creates an area for it.
8595 2002-09-03 Borut Razem <borut.razem AT siol.net>
8596 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8597 sdcc/src/pic/glue.c:
8598 introduced atexit() handler for teporay files removal in case of
8599 errors, assertions, ...
8601 2002-08-29 Borut Razem <borut.razem AT siol.net>
8602 * sdcc/support/cpp2/auto-host_vc_in.h:
8603 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8604 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8605 Maybe there is a similar problem with BORLANDC? It should be checked!
8607 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8608 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8609 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8610 was not executed, and the compiler (cl) launched a warning:
8611 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8613 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8614 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8616 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8617 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8619 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8620 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

8622 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8623 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8624 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8625 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8626 - added Release configuration in VS projects
8627 - review of compiler an linker options
8628 - VC .exe files are generated in bin_vc directory, not to interfere
8629 with binaries generated from other projects (cygwin, mingw, bcc ...)
8631 * sdcc/src/yacc.dsp: added
8633 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8634 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8635 and insert the version number definitions from .version
8637 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8639 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8640 added - genarate auto-host.h using auto-host_vc_in.h as template
8643 removed from CVS, generated automatically
8645 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8646 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8648 2002-08-11 Borut Razem <borut.razem AT siol.net>
8649 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8651 2002-08-10 Borut Razem <borut.razem AT siol.net>
8652 * src/SDCCmain.c (main):
8653 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8654 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8655 The consequence was that some temporary files were not removed.
8658 unification of code in functions tempfilename() and tempfile():
8659 function tempnam() is defined in Visual Studio 6.0 and .NET
8661 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8663 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8664 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8665 - removed compiler command line option /WX: Treats all warnings as errors
8666 - update a list of source files, included into the project
8668 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

8866 * sdcc/src/SDCCloop.c:
8867 Previous fix was not good. basic blocks that have "break" or "return" are
8868 not really partof a loop , but live ranges used in these blocks should
8869 be live thru the entire loop, so set partOfLoop but don't add them to
