1341 on rIfx (genCmp was broken)
1343 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1345 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

1347 * src/SDCCglobal.h (struct options),
1349 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1350 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1351 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1352 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1353 always available in leading double underscore form. The C99 support is
1354 mostly missing, but it's a start.
1355 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1356 reserved identifier "__data".
1358 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1404 2005-03-20 Borut Razem <borut.razem AT siol.net>
1406 * support/scripts/inc2h.pl: WIN32 port

1434 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1436 * device/lib/printf_large.c: removed inline assembly for portability and
1437 readability. Use printf_fast if speed or size are more important.
1438 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1439 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1441 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1443 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1444 prevent compiler warning
1446 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1448 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1449 moved to level 0 and declared as static. Also they are explicit
1450 placed in access bank. This was necessery because some times they
1451 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1452 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1453 optimizations. Currently only compare to unsigned char is implemented,
1454 * src/pic16/gen.c: added fReturnIdx array,
1455 * (struct resolvedIfx) is moved to gen.h and made public,
1456 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1457 * (aopForSym): added an optimization to directly store in stack of
1458 the operand of a SEND iCode,
1459 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1460 but as registers instead (AOP_REG) using the fReturnIdx array,
1461 * (pic16_freeAsmop): remove the freed register from the
1462 _G.sregsAlloc field,
1463 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1464 a compare of 'WREG',
1465 * (pic16_popGetTempRegCond): changed function prototype, now
1466 function takes also a bitVector argument v which holds the current
1467 set of registers that are allocated for stack access by aopForSym,
1468 registers allocated in aopForSym for accessing stack symbols are not
1469 any more part of the functions usedRegs field,
1470 * (genCall): some times aopOp is called for a stack variable to be
1471 send, aopForSym might perform the push, if this is true make sure
1472 that genCall doesn't push the variable twice by testing _G.resDirect,
1473 * (genFunction): changed testing for unspecified interrupt number
1474 from 256 to INTNO_UNSPEC,
1475 * modified selection scheme of frame pointer generation. Previously
1476 if function did use local registers a frame pointer was generated,
1477 now a frame pointer is generated only if function has arguments
1478 (that need PLUSW2 register access), or has stack arguments, or the
1479 compiler is not instructed to omit the frame pointer,
1480 * (genEndFunction): before restoring local registers that were saved
1481 in the function preamble, also restore the registers that *might*
1482 have been allocated for stack access,
1483 * (genRet): removed some old comments,
1484 * (genCmp, the active (RN's) version): added a call to the
1485 pic16_genCmp_special function to perform the compare with a more
1486 robust and optimized way,
1487 * (genInline): a feature has been added in inline code generation,
1488 which allows a wildcard variable substitution when writing inline
1489 assembly. Code is incomplete and experimental therefore undocumented,
1490 * (genCast): changed order of aopOp for result and right to allow
1491 aopForSym to directly load the result if possible,
1492 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1493 perform an optimized compare on some selected special occasions,
1494 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1495 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1496 generate an IVT any more,
1497 * src/pic16/main.c (pic16_optionsTable): added command line option
1499 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1500 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1502 * src/pic16/NOTES: Raphael Neider added in list of active developers
1503 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1504 jumptable_end to prevent bug #,
1505 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1506 inCond and outCond fields,
1507 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1508 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1509 turn off register spilling,
1510 * (packRegsForOneUse): synced with other ports' versions although it
1511 is not used currently,
1512 * (pic16_packRegisters): added an optimization while reading
1513 structure bitfields, some registers may be saved (malloc code is
1514 decreased by 80 bytes)
1516 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1518 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1519 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1520 this can be optimized more?
1522 2005-03-10 Raphael Neider <rneider AT web.de>
1524 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1525 genNearPointerGet): (hopefully) fixed access to bitfields via
1526 pointers (p->bitN = x; and x = p->bitN; failed)
1528 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1705 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1706 (sizeof(sectNames) changed to sizeof(sectName))
1707 Both patches fix segfaults under MinGW.

1713 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1714 of (byte sized) temporaries (assign them to WREG for now)
1715 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1716 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1717 this might fix SIGSEGVs on MinGW...
1718 * src/SDCCopt.c (killDeadCode): restored original behaviour
1719 (volatile operands might get thrown away though)
1721 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2185 * src/pic16/genarith.c,
2188 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2190 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2192 Large cummulative patch for pic16 port.
2193 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2194 to call when a stack overflow occurs,
2195 * (malloc.h): added CVS Id tag,
2196 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2198 * added libc directory. The current version of LibC contains string
2199 functions, ctype functions and macros and some functions of the
2200 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2201 be extensively tested in the future. Standard disclaimer here.
2202 Library is not automatically build yet. But one can build it by
2203 invoking 'make' inside the libc directory.
2204 * added ADC library under libio. Preliminary version yet.
2206 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2207 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2208 aopForRemat() now and not by pic16_aopOp(),
2209 * (pic16_popGetTempReg): removed warning messgae when allocating
2210 temporary registers, its a buggy feature and will be removed,
2211 * (pic16_popGet): set register instance field in AOP_CRY,
2212 * (pic16_outBitC): fixed for results in size greater than 1,
2213 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2214 * (pic16_storeForReturn): optimized return of 0,
2215 * (genCmp): experimental code for new genCmp which uses PIC18's
2216 special compare&skip instructions. Initial tests fail some times
2217 with variables grater than 1 byte in size, so new code is disabled,
2218 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2220 * (genCast): began a fix to optimize the casting of a bit to another
2221 bit, now assigning a bitfield to another bitfield will fail, sorry,
2222 * src/pic16/main.c: disabled the use of lr-support feature,
2223 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2224 * added some function prototypes, added function _debugf prototype,
2225 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2226 bits with offset (case PO_GPR_BIT),
2227 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2229 * (isBankInstruction): modified to return 0 for no banking instruction,
2230 and 1 for banking instruction,
2231 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2232 caused stop processing pCodes after a inline assembly block,
2233 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2234 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2235 registers when it shouldn't,
2236 * src/pic16/ralloc.c (allocReg): add preliminary support for
2237 supporting a limited set of temporary registers,
2239 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2241 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2242 genDataPointerSet): ensure assignments always copy in MSB to LSB
2244 (loadRegFromAop): recognize CLRH optimization,
2245 (genFunction): optimize RECEIVE iCodes in reentrant functions
2247 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2249 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2250 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2252 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5247 loaded with the linker search paths (-L arguments) and the libraries
5248 to be linked with the current source (-l arguments). Changes
5249 currently will affect only the pic16 port.
5250 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5251 include path the port specific paths and port specific libraries,

5272 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5273 when generating output files to configure the pic16 library,
5274 but now I've commented it out, since gputils aren't installed in the
5275 SF compile farm, so library won't compile
5277 * device/lib/Makefile.in (version 1.56): initially I've added in
5278 target 'all' the prerequestive 'model-pic16' so it compiled the
5279 pic16 library, but now I've commented it out for the same reasons
5281 * added targets 'model-pic16' and 'objects-pic16' to compile the
5283 * added target 'port-specific-objects-pic16' to handle the
5284 generated libraries and copy them into the build/ directory
5285 * added target 'clean-intermediate-pic16' to clean intermediate
5286 files into pic16 directory
5287 * in target 'installdirs' added line to create directory pic16 in
5288 the installation path
5290 * device/include/Makefile.in (version 1.11): in target 'install'
5291 added lines to copy all header files to installation path,
5292 * in target 'installdirs' added line create directory for pic16
5293 headers in the installation path
5295 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5308 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5309 option so that it actually works. Made it specific to the z80, since
5310 the gbz80 doesn't have these kinds of I/O ports.
5312 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5314 * device/include/z180.h,

5320 * device/lib/_strcmp.c,
5321 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5322 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5323 portmode; added deprecation warning for bank= and protmode= forms.
5324 Also, guard against buffer overflow.
5325 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5327 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5329 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5330 changed interrupt vector table generation to only emit declared vectors.

5332 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5334 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5336 Mainly changes to support compilation of the device libraries
5337 * src/pic16/device.c: stack is allocated via symbol and not
5338 via literal number. The symbol is placed in the corresponding
5339 position of the data ram
5340 * (pic16_dump_section): relocatable and absolute uninitialized
5341 data are now emitted in sorted order to reduce section naming,
5342 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5343 weren't marked as being in the access bank,
5345 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5347 Added portion of GNU PIC Library under the directory
5348 device/include/pic16 and device/lib/pic16. These files
5349 contain the declarations of SFRs for the PIC18Fxx2 devices.
5350 The directory is initialized via configure from toplevel.
5352 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5354 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5355 the spilllocations to be compared correctly
5357 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5359 * src/SDCCast.c (decorateType): fixed bug introduced today
5361 2004-01-12 Borut Razem <borut.razem AT siol.net>
5363 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5379 * doc/sdccman.lyx: Moved and added some sections, small changes
5380 all over. Telling LaTeX to be less strict with word spacing
5381 to better keep the right margin. Changed some notes about
5382 maintainance of the ports in section 3.2.1 - is it OK like this?
5384 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5421 UPPER for immediate operands,
5422 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5424 * src/pic16/peeph.def: all peepholes with movff are commented out,
5425 because there is a problem in the pcode peep optimizer,
5426 * src/pic16/ralloc.c: the register allocator can now reuse local

5428 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5430 Added file src/pic16/NOTES with information about program writing on
5431 the current port version.

5519 include information about variables allocated to the overlay
5522 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5524 * as/mcs51/lkmain.c: Help about -Y option

5536 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5538 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5539 (default behaviour).
5541 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5543 A python script to validate compiler diagnostic messages. It can be
5544 used to verify that sdcc complains about bad c source code and
5545 gives a good location of the error.
5546 * support/valdiag/Makefile,
5547 * support/valdiag/valdiag.py,
5548 * support/valdiag/tests/*
5550 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5565 Bug reported from Jesus Calvino-Fraga
5567 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5569 * sdcc.spec: updated
5570 * device/include/Makefile.in: don't install CVS directories
5571 * device/lib/Makefile.in: added removal of CVS directories after install
5572 * doc/Makefile: fixed install, added local_icons
5573 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5574 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5575 * src/ds390/gen.c (genRightShift): fixed bug #870788
5576 * src/SDCCast.c (decorateType): fixed bug #870781
5578 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5580 PIC16 port related changes:
5581 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5582 added variable stackPos,
5584 * gen.c: genCall, assignResultValue: added support for
5585 pushing/retrieving function parameters to/from stack,
5586 genFunction,genEndFunction: setup stack frame for the
5588 genAddrOf: will be changed according to bug 863624
5590 * added files genutils.c and genutils.h which contain gen*
5591 debugged and optimised functions extracted from gen.c
5593 * glue.c: added variable 'externs' which holds extern symbols,
5594 pic16emitRegularMap: is modified to properly handle relocatable
5595 symbols under the new scheme,
5596 pic16createInterruptVect: is modified
5597 pic16printPublics: is modified to emit 'global' assembler directives,
5598 added pic16_printExterns to print extern symbols,
5599 pic16glue: initializes stack/frame pointer in the beginning of
5600 the assembly output. Temporary hack, will be corrected later,
5601 because gplink yet does not support stack and SDCC does not
5602 yet support a type of crt0.o object to create the final binary.
5604 * Removed many lines that contain 8051 legacy code.
5605 * The code is finally placed under a 'code' directive.
5606 * Added port specific options.
5608 * _process_pragma: simplified since now we do not need *special*
5609 include file to define SFR registers. But a separate header
5610 will be needed. This will be developed later.
5611 * _pic16_parseOptions: added, parses port specific options:
5612 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5613 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5614 --preplace-udata-with=
5616 * _pic16_setDefaultOptions: modified to initialize section names,
5617 but hack is temporarly out of order since it needs improvement.
5618 * _pic16_genAssemblerPreamble: configuration words are emitted by
5619 their address instead of their name. This part is incomplete and
5620 supports only the 18Fxx2 devices. Other devices will emit an error
5621 during assembly since they do not contain the same set of config
5623 * _pic16_genIVT: is modified,
5625 * pcode.c: added definitions for some hardware registers that are needed
5627 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5628 All PCI entries are updated. Now LFSR is supported.
5629 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5630 * added pic16_newpCodeOpLit2 to support instructions with
5631 two literal arguments
5632 * pic16_pCode2str: corrected code that emits assembler instructions
5633 with two literal operands and those that have an access bit modifier
5634 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5635 this fixes a bug which caused some labels to be lost, when an
5636 assembler directive was added, i.e. banksel,
5637 * pic16_FixRegisterBanking: improved logic that causes the insertion
5639 * InlineFunction: functions that are called once, are not any more
5640 inlined. This can be a port option in the future,
5642 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5644 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5645 hold the corresponding uninitialized symbols,
5646 * pic16_allocProcessorRegister: registers have explicit marked the
5648 * pic16_allocInternalRegister: registers are explicit marked as
5650 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5651 processing list, so bit registers were lost,
5654 * ralloc.h: added field 'accessBank' and original symbol operand
5655 in register definition,
5656 * removed the field isMapped from register definition,
5658 ** Several functions have been removed from various sources:
5659 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5660 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5661 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5662 pic16_assignRelocatableRegisters
5664 ** others have been introduced:
5665 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5666 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5668 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5670 * support/scripts/inc2h.pl: changed definition of BIT_AT
5671 to emit 'sbit at' instead of 'bit at'. This was a request.
5673 PIC16 port related preliminary changes:
5674 * gen.c: prefixed function popRegFromString with
5675 pic16_ and all references to it corrected
5676 * pcode.c: all pic16_pc_* hardware registers prefixed
5677 with underscore (_),
5678 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5679 * ralloc.c: newReg(): when register is REG_SFR then
5680 set address to rIdx,
5681 pic16_allocProcessorRegister(): marks register wasUsed=0
5682 pic16_writeUsedRegs(): added a call to assign processor
5683 registers via pic16_assignFixedRegisters
5685 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5687 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5688 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5689 variables in unused register banks. Also the SSEG is placed
5690 wherever there is enough space for it, and IDATA can be anywhere
5691 in internal RAM. For now compile using -Wl-Y[stack_size].
5692 The mem file is different for this option as well, since it
5693 makes no sense of talking about DSEG lenght.
5695 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5697 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5698 in certain cases, e.g. when ROM assignment, patch provided
5699 from Albert den Haan.
5701 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6744 A few small changes that speed up the peephole optimizer.
6748 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6750 Try to make the peephole optimizer smarter by maintaining
6751 an association between the assembly source code and the
6752 iCodes that originated them. Put this information to use
6753 with a new peephole rule condition "notVolatile" so that
6754 the rules can be aggressive yet still safe.

6767 if the left or right operand symbols have the accuse flag set.
6769 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6771 Changed the type of the result of the ! (NOT) operator to char;
6772 previously it returned the same type as the source. This allows
6773 us to eliminate all the genFloatNot functions (all of its target
6774 implementations were very buggy) since !float can use the same
6777 * src/SDCCicode.c (ast2iCode): ! returns char

6786 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6787 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6788 during interrupts. Ensure WSAVE is located at a shared bank address.
6789 2. Fixed page selection in some places
6790 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6791 the registers name strings.
6792 4. Fixed "signed / unsigned compare" compiler warnings.
6793 5. The PIC port manages its own allocation of the general purpose
6794 registers, but makes no attempt to reuse them. As a result when
6795 compiling it soon runs out of general purpose registers. Some
6796 additional code was added to the files pcode.c and device.c to walk
6797 through the function call tree and rename the registers so that they
6807 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6814 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6816 Made bitfield a distinct type from bit so that bitfields
6817 convert as per ANSI C and bits retain their traditional
6818 boolean style behaviour. Implemented bitfield support in
6826 * src/ds390/gen.c: bit v bitfield split
6827 * src/z80/gen.c: New support for bitfields
6828 * support/regression/tests/bitfields.c: reenabled z80,
6831 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6833 Rules 246.x, 247.x relate to bitfields, the others speed up
6834 access to xdata mapped I/O devices.
6836 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6838 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6840 Cleaned up genPackBits and genUnpackBits and added two helper
6841 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6842 for literal assignments in genPackBits (thanks to Frieder for
6848 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6850 Fixed bug #748310 (pointer to function type mishandled when the
6851 function name is omitted). Also fixed a SIGSEGV when a function
6852 attribute (reentrant, etc) is used on a non-function or on a
6853 function but misplaced before the parameter list.

6880 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6882 Made the constant following the "interrupt" keyword optional. If
6883 omitted, the function will not automatically be given an entry
6884 in the interrupt vector table (similar to #pragma NOIV, but
6885 less syntacticly kludgy). The interrupt number is also now
6886 range checked. Also fixed a bug in the high order bit example

7362 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7363 the regression tests I'm not brave enough to enable 245.b, 245.c
7364 * doc/sdccman.lyx: added latex preamble for hyperref package.
7365 Using pdflatex this will give you a hyperlinked pdf file with
7366 bookmarks. (prepend '%' before /usepackage if this breaks something)

7407 it can be defined with CFLAGS when running configure
7408 * src/SDCCmain.c: fixed compiling + linking with object files
7410 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7413 added --disable-pic16-port
7414 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7415 * src/SDCCmain.c: linkOptions is changed to set *,
7416 added if/endif conditional macros to remove options help
7417 messages from optionsTable when a port is not configured, added
7418 support for the PIc16 port in the ports table, when executing
7419 the compiler with no port specified on command line, a default
7420 port is selected with the new macro DEFAULT_PORT which is
7421 defined in port.h, in setDefaultOptions() linkOptions is removed
7422 from initialization assignment, since now it is a set,
7423 parseCmdLine uses setParseWithComma for linkOptions, in
7424 linkEdit() linkOptions are accessed with new function indexSet()
7425 which returns the i'th item of a set variable. See SDCCset.c, in
7426 linkEdit() when calling buildCmdLine(), added linkOptions as
7427 last argument. Now users can pass arguments to gplink via the
7428 -Wl option, main() uses pic16glue() to glue up pic16 programs
7429 * src/SDCCpeeph.c: various changes to support pic16

7440 * src/pic16/glue.c: commented out some error producing lines
7441 * src/pic16/main.c: __config directives are commented out to stop
7442 gpasm complaining and test the linkage with gplink, _linkCmd and
7443 _asmCmd changed to be more gplink and gpasm friendly
7444 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7445 produced an error when parsed, peep rule 12 is added to utilize
7446 movff, but it is commented out since the pCode does not support
7447 yet a command with 2 address arguments
7449 2003-05-18 <johan AT balder>
7451 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7476 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7478 2003-05-11 Borut Razem <borut.razem AT siol.net>
7480 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7481 the path of bin directory, so that PATH is the only env. variable, which has to be set
7482 in case of standard installation.
7483 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8486 * src/SDCCicode.c: fixed array add
8488 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8489 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8490 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8492 2003-01-04 <johan AT balder>
8494 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8496 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8497 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8499 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8500 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8509 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8510 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8512 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8514 * in \sdcc\as\mcs51\ changed these files in order to create an
8515 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8516 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8517 following files to include the previous two files: aslink.dsp,
8518 Makefile.aslink, Makefile.bcc, and Makefile.in.
8520 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8521 .adb instead of .cdb
8523 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8525 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8526 value from option --iram-size.
8528 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8530 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8533 2002-09-18 <wiml AT hhhh.org>
8535 * SDCClrange.h: exposed setFromRange() and setToRange()
8536 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8537 packRegsForAccUse() (bug 542397)
8538 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8539 multiple times and emitting the fetch operations more than once
8540 added aopGetUsesAcc() function to allow binary operators to
8541 fetch their operands in the correct order; made genMinus() emit
8542 compact code for X = LITERAL - Y
8544 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8545 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8546 sprintf() in line 1267.
8548 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8549 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8552 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8553 Changes to aslink (All the changes are marked with 'JCF'):
8555 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8558 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8559 area BSEG. Also moves, if possible, the DATA area down into the internal
8560 ram so more space is available.
8562 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8565 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8566 not bytes. Function summary() which creates a memory usage summary
8567 file with extension .mem. Reports of overlaping stack and small stack
8568 size. If the space for the stack is less than 16 bytes aslink trows a
8571 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8572 the 8051. Option 'y' for memory summary output file.
8574 Changes to sdcc (All the changes are marked with 'JCF'):
8576 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8578 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8579 overlaying area for it (uses RegBankUsed[4]).
8581 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8582 bank zero as used by default. By default aslink locates the stack
8583 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8584 the creation of the .mem file. Delegates the allocation of data area
8585 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8586 the begining of the stack area to aslink.
8588 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8589 glue() in SDCCglue.c creates an area for it.
8591 2002-09-03 Borut Razem <borut.razem AT siol.net>
8592 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8593 sdcc/src/pic/glue.c:
8594 introduced atexit() handler for teporay files removal in case of
8595 errors, assertions, ...
8597 2002-08-29 Borut Razem <borut.razem AT siol.net>
8598 * sdcc/support/cpp2/auto-host_vc_in.h:
8599 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8600 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8601 Maybe there is a similar problem with BORLANDC? It should be checked!
8603 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8604 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8605 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8606 was not executed, and the compiler (cl) launched a warning:
8607 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8609 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8610 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8612 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8613 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8615 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8616 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

8619 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8620 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8621 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8622 - added Release configuration in VS projects
8623 - review of compiler an linker options
8624 - VC .exe files are generated in bin_vc directory, not to interfere
8625 with binaries generated from other projects (cygwin, mingw, bcc ...)
8627 * sdcc/src/yacc.dsp: added
8629 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8630 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8631 and insert the version number definitions from .version
8633 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8635 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8636 added - genarate auto-host.h using auto-host_vc_in.h as template
8639 removed from CVS, generated automatically
8641 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8642 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8644 2002-08-11 Borut Razem <borut.razem AT siol.net>
8645 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8647 2002-08-10 Borut Razem <borut.razem AT siol.net>
8648 * src/SDCCmain.c (main):
8649 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8650 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8651 The consequence was that some temporary files were not removed.
8654 unification of code in functions tempfilename() and tempfile():
8655 function tempnam() is defined in Visual Studio 6.0 and .NET
8657 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8659 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8660 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8661 - removed compiler command line option /WX: Treats all warnings as errors
8662 - update a list of source files, included into the project
8664 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8665 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:

8862 * sdcc/src/SDCCloop.c:
8863 Previous fix was not good. basic blocks that have "break" or "return" are
8864 not really partof a loop , but live ranges used in these blocks should
8865 be live thru the entire loop, so set partOfLoop but don't add them to
