1305 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1306 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1307 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1308 immedDom() returning wrong block; probably fixes bug #1160833)
1310 2005-03-20 Borut Razem <borut.razem AT siol.net>
1312 * support/scripts/inc2h.pl: WIN32 port
1314 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1316 * device/lib/makefile.in: added abs.c and labs.c
1318 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1320 * device/include/stdint.h: added
1321 * device/lib/abs.c: added
1322 * device/lib/labs.c: added
1323 * device/include/stdlib.h: added abs() and labs() prototypes
1324 * device/lib/libsdcc.lib: added abs and labs
1325 * device/include/float.h,
1326 * device/lib/_fsmul.c,
1327 * device/lib/printf_fast.c,
1328 * device/lib/printf_tiny.c: updated comments
1330 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1332 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1335 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1337 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1338 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1340 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1342 * device/lib/printf_large.c: removed inline assembly for portability and
1343 readability. Use printf_fast if speed or size are more important.
1344 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1345 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1347 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1349 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1350 prevent compiler warning
1352 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1354 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1355 moved to level 0 and declared as static. Also they are explicit
1356 placed in access bank. This was necessery because some times they
1357 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1358 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1359 optimizations. Currently only compare to unsigned char is implemented,
1360 * src/pic16/gen.c: added fReturnIdx array,
1361 * (struct resolvedIfx) is moved to gen.h and made public,
1362 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1363 * (aopForSym): added an optimization to directly store in stack of
1364 the operand of a SEND iCode,
1365 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1366 but as registers instead (AOP_REG) using the fReturnIdx array,
1367 * (pic16_freeAsmop): remove the freed register from the
1368 _G.sregsAlloc field,
1369 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1370 a compare of 'WREG',
1371 * (pic16_popGetTempRegCond): changed function prototype, now
1372 function takes also a bitVector argument v which holds the current
1373 set of registers that are allocated for stack access by aopForSym,
1374 registers allocated in aopForSym for accessing stack symbols are not
1375 any more part of the functions usedRegs field,
1376 * (genCall): some times aopOp is called for a stack variable to be
1377 send, aopForSym might perform the push, if this is true make sure
1378 that genCall doesn't push the variable twice by testing _G.resDirect,
1379 * (genFunction): changed testing for unspecified interrupt number
1380 from 256 to INTNO_UNSPEC,
1381 * modified selection scheme of frame pointer generation. Previously
1382 if function did use local registers a frame pointer was generated,
1383 now a frame pointer is generated only if function has arguments
1384 (that need PLUSW2 register access), or has stack arguments, or the
1385 compiler is not instructed to omit the frame pointer,
1386 * (genEndFunction): before restoring local registers that were saved
1387 in the function preamble, also restore the registers that *might*
1388 have been allocated for stack access,
1389 * (genRet): removed some old comments,
1390 * (genCmp, the active (RN's) version): added a call to the
1391 pic16_genCmp_special function to perform the compare with a more
1392 robust and optimized way,
1393 * (genInline): a feature has been added in inline code generation,
1394 which allows a wildcard variable substitution when writing inline
1395 assembly. Code is incomplete and experimental therefore undocumented,
1396 * (genCast): changed order of aopOp for result and right to allow
1397 aopForSym to directly load the result if possible,
1398 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1399 perform an optimized compare on some selected special occasions,
1400 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1401 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1402 generate an IVT any more,
1403 * src/pic16/main.c (pic16_optionsTable): added command line option
1405 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1406 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1408 * src/pic16/NOTES: Raphael Neider added in list of active developers
1409 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1410 jumptable_end to prevent bug #,
1411 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1412 inCond and outCond fields,
1413 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1414 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1415 turn off register spilling,
1416 * (packRegsForOneUse): synced with other ports' versions although it
1417 is not used currently,
1418 * (pic16_packRegisters): added an optimization while reading
1419 structure bitfields, some registers may be saved (malloc code is
1420 decreased by 80 bytes)
1422 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1424 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1425 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1426 this can be optimized more?
1428 2005-03-10 Raphael Neider <rneider AT web.de>
1430 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1431 genNearPointerGet): (hopefully) fixed access to bitfields via
1432 pointers (p->bitN = x; and x = p->bitN; failed)
1434 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1477 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1478 to keep the correct label reference count when adding/removing references
1479 to labels. A peephole file using this is appended to patch #1144962.

1622 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1623 this might fix SIGSEGVs on MinGW...

2104 * added libc directory. The current version of LibC contains string
2105 functions, ctype functions and macros and some functions of the
2106 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2107 be extensively tested in the future. Standard disclaimer here.

2121 * (genCmp): experimental code for new genCmp which uses PIC18's
2122 special compare&skip instructions. Initial tests fail some times
2123 with variables grater than 1 byte in size, so new code is disabled,
2124 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2126 * (genCast): began a fix to optimize the casting of a bit to another
2127 bit, now assigning a bitfield to another bitfield will fail, sorry,

2136 and 1 for banking instruction,
2137 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2138 caused stop processing pCodes after a inline assembly block,

2141 registers when it shouldn't,
2142 * src/pic16/ralloc.c (allocReg): add preliminary support for
2143 supporting a limited set of temporary registers,
2145 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2147 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2148 genDataPointerSet): ensure assignments always copy in MSB to LSB
2150 (loadRegFromAop): recognize CLRH optimization,
2151 (genFunction): optimize RECEIVE iCodes in reentrant functions
2153 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2155 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2164 * device/lib/_gptrget.c (_gptrget),
2165 * device/lib/_gptrgetc.c (_gptrgetc),
2166 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2167 instead of sjmp to ret
2168 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided

5153 loaded with the linker search paths (-L arguments) and the libraries
5154 to be linked with the current source (-l arguments). Changes
5155 currently will affect only the pic16 port.
5156 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5157 include path the port specific paths and port specific libraries,
5158 * gplink command now contains the $3 argument,
5159 * src/pic16/device.h,
5160 * src/pic16/device.c,: structure PIC_device is made public and

5176 Documenting changes from previous commits.
5177 * configure.in (version 1.56),
5178 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5179 when generating output files to configure the pic16 library,
5180 but now I've commented it out, since gputils aren't installed in the
5181 SF compile farm, so library won't compile
5183 * device/lib/Makefile.in (version 1.56): initially I've added in
5184 target 'all' the prerequestive 'model-pic16' so it compiled the
5185 pic16 library, but now I've commented it out for the same reasons
5187 * added targets 'model-pic16' and 'objects-pic16' to compile the
5189 * added target 'port-specific-objects-pic16' to handle the
5190 generated libraries and copy them into the build/ directory
5191 * added target 'clean-intermediate-pic16' to clean intermediate
5192 files into pic16 directory
5193 * in target 'installdirs' added line to create directory pic16 in
5194 the installation path

5197 added lines to copy all header files to installation path,
5198 * in target 'installdirs' added line create directory for pic16
5199 headers in the installation path

5215 option so that it actually works. Made it specific to the z80, since
5216 the gbz80 doesn't have these kinds of I/O ports.
5218 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5220 * device/include/z180.h,

5244 via literal number. The symbol is placed in the corresponding
5245 position of the data ram
5246 * (pic16_dump_section): relocatable and absolute uninitialized
5247 data are now emitted in sorted order to reduce section naming,
5248 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5249 weren't marked as being in the access bank,
5251 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5253 Added portion of GNU PIC Library under the directory
5254 device/include/pic16 and device/lib/pic16. These files
5255 contain the declarations of SFRs for the PIC18Fxx2 devices.
5256 The directory is initialized via configure from toplevel.

5287 to better keep the right margin. Changed some notes about
5288 maintainance of the ports in section 3.2.1 - is it OK like this?
5290 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5327 UPPER for immediate operands,
5328 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5330 * src/pic16/peeph.def: all peepholes with movff are commented out,
5331 because there is a problem in the pcode peep optimizer,
5332 * src/pic16/ralloc.c: the register allocator can now reuse local

5425 include information about variables allocated to the overlay
5428 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5430 * as/mcs51/lkmain.c: Help about -Y option

5442 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5444 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5445 (default behaviour).
5447 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5449 A python script to validate compiler diagnostic messages. It can be
5450 used to verify that sdcc complains about bad c source code and
5451 gives a good location of the error.
5452 * support/valdiag/Makefile,
5453 * support/valdiag/valdiag.py,
5454 * support/valdiag/tests/*

5471 Bug reported from Jesus Calvino-Fraga
5473 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5475 * sdcc.spec: updated
5476 * device/include/Makefile.in: don't install CVS directories
5477 * device/lib/Makefile.in: added removal of CVS directories after install
5478 * doc/Makefile: fixed install, added local_icons
5479 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5480 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5481 * src/ds390/gen.c (genRightShift): fixed bug #870788
5482 * src/SDCCast.c (decorateType): fixed bug #870781
5484 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5486 PIC16 port related changes:
5487 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5488 added variable stackPos,
5490 * gen.c: genCall, assignResultValue: added support for
5491 pushing/retrieving function parameters to/from stack,
5492 genFunction,genEndFunction: setup stack frame for the
5494 genAddrOf: will be changed according to bug 863624
5496 * added files genutils.c and genutils.h which contain gen*
5497 debugged and optimised functions extracted from gen.c
5499 * glue.c: added variable 'externs' which holds extern symbols,
5500 pic16emitRegularMap: is modified to properly handle relocatable
5501 symbols under the new scheme,
5502 pic16createInterruptVect: is modified
5503 pic16printPublics: is modified to emit 'global' assembler directives,
5504 added pic16_printExterns to print extern symbols,
5505 pic16glue: initializes stack/frame pointer in the beginning of
5506 the assembly output. Temporary hack, will be corrected later,
5507 because gplink yet does not support stack and SDCC does not
5508 yet support a type of crt0.o object to create the final binary.
5510 * Removed many lines that contain 8051 legacy code.
5511 * The code is finally placed under a 'code' directive.
5512 * Added port specific options.
5514 * _process_pragma: simplified since now we do not need *special*
5515 include file to define SFR registers. But a separate header
5516 will be needed. This will be developed later.
5517 * _pic16_parseOptions: added, parses port specific options:
5518 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5519 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5520 --preplace-udata-with=
5522 * _pic16_setDefaultOptions: modified to initialize section names,
5523 but hack is temporarly out of order since it needs improvement.
5524 * _pic16_genAssemblerPreamble: configuration words are emitted by
5525 their address instead of their name. This part is incomplete and
5526 supports only the 18Fxx2 devices. Other devices will emit an error
5527 during assembly since they do not contain the same set of config
5529 * _pic16_genIVT: is modified,
5531 * pcode.c: added definitions for some hardware registers that are needed
5533 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5534 All PCI entries are updated. Now LFSR is supported.
5535 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5536 * added pic16_newpCodeOpLit2 to support instructions with
5537 two literal arguments
5538 * pic16_pCode2str: corrected code that emits assembler instructions
5539 with two literal operands and those that have an access bit modifier
5540 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5541 this fixes a bug which caused some labels to be lost, when an
5542 assembler directive was added, i.e. banksel,
5543 * pic16_FixRegisterBanking: improved logic that causes the insertion
5545 * InlineFunction: functions that are called once, are not any more
5546 inlined. This can be a port option in the future,
5548 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5550 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5551 hold the corresponding uninitialized symbols,
5552 * pic16_allocProcessorRegister: registers have explicit marked the
5554 * pic16_allocInternalRegister: registers are explicit marked as
5556 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5557 processing list, so bit registers were lost,
5560 * ralloc.h: added field 'accessBank' and original symbol operand
5561 in register definition,
5562 * removed the field isMapped from register definition,
5564 ** Several functions have been removed from various sources:
5565 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5566 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5567 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5568 pic16_assignRelocatableRegisters
5570 ** others have been introduced:
5571 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5572 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5574 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5576 * support/scripts/inc2h.pl: changed definition of BIT_AT
5577 to emit 'sbit at' instead of 'bit at'. This was a request.
5579 PIC16 port related preliminary changes:
5580 * gen.c: prefixed function popRegFromString with
5581 pic16_ and all references to it corrected
5582 * pcode.c: all pic16_pc_* hardware registers prefixed
5583 with underscore (_),
5584 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5585 * ralloc.c: newReg(): when register is REG_SFR then
5586 set address to rIdx,
5587 pic16_allocProcessorRegister(): marks register wasUsed=0
5588 pic16_writeUsedRegs(): added a call to assign processor
5589 registers via pic16_assignFixedRegisters
5591 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5593 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5594 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5595 variables in unused register banks. Also the SSEG is placed
5596 wherever there is enough space for it, and IDATA can be anywhere
5597 in internal RAM. For now compile using -Wl-Y[stack_size].
5598 The mem file is different for this option as well, since it
5599 makes no sense of talking about DSEG lenght.
5601 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5603 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5604 in certain cases, e.g. when ROM assignment, patch provided
5605 from Albert den Haan.
5607 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5750 * src/mcs51/peephole.def,
5751 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5752 (allows non-interrupt and interrupt code to safely compete for a resource

6492 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
6493 support for standard C idiom of memory mapped variables; for
6494 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6495 to xdata int at 0x1234 tempvar = 1.
6496 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6497 provided by Akiya ISHIDA

6513 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6515 Fixed bug #621531 (const & volatile confusion in the type chain).
6516 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6517 refer to the const or volatile state of the pointer itself.

6595 * src/mcs51/gen.c (leftRightUseAcc),
6596 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
6597 iCode properly now. Use getSize instead of nRegs since a & b
6598 aren't part of the nRegs tally.
6600 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
6602 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

6604 before instructions that use the _STATUS register
6606 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
6608 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6609 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6610 fetching of the pointer
6611 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6612 copied from genNearPointerSet()
6613 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6614 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6615 If they pop r0/r1 they must be called in the opposite order than aopOp().
6616 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6617 (resp. --stack-auto), prepared for --xstack

6626 these ports have their own __sdcc_external_start()
6628 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6630 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6631 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6632 type for bits was changed. It resulted in bit variables becoming
6633 global, which is not permitted in PIC 14 assembly output.
6635 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6637 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6641 Z80 and MCS51 linkers complaint if a public symbol is defined
6642 in more than one library module:
6646 * as/mcs51/Makefile.in
6648 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6650 A few small changes that speed up the peephole optimizer.
6654 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6656 Try to make the peephole optimizer smarter by maintaining
6657 an association between the assembly source code and the
6658 iCodes that originated them. Put this information to use
6659 with a new peephole rule condition "notVolatile" so that
6660 the rules can be aggressive yet still safe.
6665 * src/mcs51/peeph.def
6667 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6671 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6672 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6673 if the left or right operand symbols have the accuse flag set.
6675 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6677 Changed the type of the result of the ! (NOT) operator to char;
6678 previously it returned the same type as the source. This allows
6679 us to eliminate all the genFloatNot functions (all of its target
6680 implementations were very buggy) since !float can use the same
6683 * src/SDCCicode.c (ast2iCode): ! returns char
6684 * src/mcs51/gen.c (genNot, genNotFloat),
6685 * src/ds390/gen.c (genNot, genNotFloat),
6686 * src/z80/gen.c (genNot, genNotFloat),
6687 * src/pic/gen.c (genNot, genNotFloat),
6688 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6690 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6692 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6693 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6694 during interrupts. Ensure WSAVE is located at a shared bank address.
6695 2. Fixed page selection in some places
6696 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6697 the registers name strings.
6698 4. Fixed "signed / unsigned compare" compiler warnings.
6699 5. The PIC port manages its own allocation of the general purpose
6700 registers, but makes no attempt to reuse them. As a result when
6701 compiling it soon runs out of general purpose registers. Some
6702 additional code was added to the files pcode.c and device.c to walk
6703 through the function call tree and rename the registers so that they
6713 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6714 genPlus() & genMinus() when the result is the same as left or right
6716 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6720 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6722 Made bitfield a distinct type from bit so that bitfields
6723 convert as per ANSI C and bits retain their traditional
6724 boolean style behaviour. Implemented bitfield support in
6732 * src/ds390/gen.c: bit v bitfield split
6733 * src/z80/gen.c: New support for bitfields
6734 * support/regression/tests/bitfields.c: reenabled z80,
6737 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6739 Rules 246.x, 247.x relate to bitfields, the others speed up
6740 access to xdata mapped I/O devices.
6742 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6744 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6746 Cleaned up genPackBits and genUnpackBits and added two helper
6747 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6748 for literal assignments in genPackBits (thanks to Frieder for
6754 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6756 Fixed bug #748310 (pointer to function type mishandled when the
6757 function name is omitted). Also fixed a SIGSEGV when a function
6758 attribute (reentrant, etc) is used on a non-function or on a
6759 function but misplaced before the parameter list.
6761 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6763 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6764 * support/Util/SDCCerr.h,
6765 * support/Util/SDCCerr.c: Added func attr misuse error msg
6767 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6769 Fixed bug #787649 by anonymous
6770 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
6771 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
6773 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6775 Fixed numerous bitfield problems.
6777 * src/SDCC.y: More bitfield related error checking
6779 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
6780 * support/Util/SDCCerr.h,
6781 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs

6783 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
6784 * support/regression/tests/bitfields.c: tests added
6786 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6788 Made the constant following the "interrupt" keyword optional. If
6789 omitted, the function will not automatically be given an entry
6790 in the interrupt vector table (similar to #pragma NOIV, but
6791 less syntacticly kludgy). The interrupt number is also now
6792 range checked. Also fixed a bug in the high order bit example

7319 added --disable-pic16-port
7320 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7321 * src/SDCCmain.c: linkOptions is changed to set *,
7322 added if/endif conditional macros to remove options help
7323 messages from optionsTable when a port is not configured, added
7324 support for the PIc16 port in the ports table, when executing
7325 the compiler with no port specified on command line, a default
7326 port is selected with the new macro DEFAULT_PORT which is
7327 defined in port.h, in setDefaultOptions() linkOptions is removed
7328 from initialization assignment, since now it is a set,
7329 parseCmdLine uses setParseWithComma for linkOptions, in
7330 linkEdit() linkOptions are accessed with new function indexSet()
7331 which returns the i'th item of a set variable. See SDCCset.c, in
7332 linkEdit() when calling buildCmdLine(), added linkOptions as
7333 last argument. Now users can pass arguments to gplink via the
7334 -Wl option, main() uses pic16glue() to glue up pic16 programs

7346 * src/pic16/glue.c: commented out some error producing lines
7347 * src/pic16/main.c: __config directives are commented out to stop
7348 gpasm complaining and test the linkage with gplink, _linkCmd and
7349 _asmCmd changed to be more gplink and gpasm friendly
7350 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7351 produced an error when parsed, peep rule 12 is added to utilize
7352 movff, but it is commented out since the pCode does not support
7353 yet a command with 2 address arguments

8398 2003-01-04 <johan AT balder>
8400 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8402 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8403 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8405 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8415 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8416 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8418 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8420 * in \sdcc\as\mcs51\ changed these files in order to create an
8421 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8422 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8423 following files to include the previous two files: aslink.dsp,
8424 Makefile.aslink, Makefile.bcc, and Makefile.in.
8426 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8427 .adb instead of .cdb
8429 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8431 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8432 value from option --iram-size.
8434 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8436 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8439 2002-09-18 <wiml AT hhhh.org>
8441 * SDCClrange.h: exposed setFromRange() and setToRange()
8442 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8443 packRegsForAccUse() (bug 542397)
8444 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8445 multiple times and emitting the fetch operations more than once
8446 added aopGetUsesAcc() function to allow binary operators to
8447 fetch their operands in the correct order; made genMinus() emit
8448 compact code for X = LITERAL - Y
8450 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8451 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8452 sprintf() in line 1267.
8454 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8455 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8458 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8459 Changes to aslink (All the changes are marked with 'JCF'):
8461 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8464 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8465 area BSEG. Also moves, if possible, the DATA area down into the internal
8466 ram so more space is available.
8468 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8471 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8472 not bytes. Function summary() which creates a memory usage summary
8473 file with extension .mem. Reports of overlaping stack and small stack
8474 size. If the space for the stack is less than 16 bytes aslink trows a
8477 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8478 the 8051. Option 'y' for memory summary output file.
8480 Changes to sdcc (All the changes are marked with 'JCF'):
8482 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8484 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8485 overlaying area for it (uses RegBankUsed[4]).
8487 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8488 bank zero as used by default. By default aslink locates the stack
8489 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8490 the creation of the .mem file. Delegates the allocation of data area
8491 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8492 the begining of the stack area to aslink.
8494 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8495 glue() in SDCCglue.c creates an area for it.
8497 2002-09-03 Borut Razem <borut.razem AT siol.net>
8498 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8499 sdcc/src/pic/glue.c:
8500 introduced atexit() handler for teporay files removal in case of
8501 errors, assertions, ...
8503 2002-08-29 Borut Razem <borut.razem AT siol.net>
8504 * sdcc/support/cpp2/auto-host_vc_in.h:
8505 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8506 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8507 Maybe there is a similar problem with BORLANDC? It should be checked!
8509 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8510 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8511 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8512 was not executed, and the compiler (cl) launched a warning:
8513 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8515 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8516 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8518 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8519 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8521 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8522 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8523 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8524 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8525 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8526 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8527 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8528 - added Release configuration in VS projects
8529 - review of compiler an linker options
8530 - VC .exe files are generated in bin_vc directory, not to interfere
8531 with binaries generated from other projects (cygwin, mingw, bcc ...)
8533 * sdcc/src/yacc.dsp: added
8535 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8536 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8537 and insert the version number definitions from .version
8539 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8541 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8542 added - genarate auto-host.h using auto-host_vc_in.h as template
8545 removed from CVS, generated automatically
8547 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8548 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8550 2002-08-11 Borut Razem <borut.razem AT siol.net>
8551 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8553 2002-08-10 Borut Razem <borut.razem AT siol.net>
8554 * src/SDCCmain.c (main):
8555 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8556 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8557 The consequence was that some temporary files were not removed.
8560 unification of code in functions tempfilename() and tempfile():
8561 function tempnam() is defined in Visual Studio 6.0 and .NET
8563 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8565 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8566 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8567 - removed compiler command line option /WX: Treats all warnings as errors
8568 - update a list of source files, included into the project
8570 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8571 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8572 changed project type to Generic Project so that can be correcly converted to VS.NET project
8574 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8576 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8578 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8580 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8581 added return 0 statements after assert() to make compiler happy
8583 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8584 added newline in the def file to keep MSC compiler satisfied
8586 * sdcc/src/z80/gen.c:
8587 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8588 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8589 - solved MSC error in function aopDump()
8591 * sdcc_vc.h: define PREFIX as "\\sdcc"
8593 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8594 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8597 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8598 - Rewrote the register banking algorithm.
8599 - Added pCode live-range analysis to registers (for now, only non-used and
8600 singly-used registers optimized away)
8602 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8604 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

8633 2002-03-28 Johan Knol <johan AT balder>
8635 * src/SDCCval.c: fixed bug #532436
8637 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8639 Added "char *Processor" field to the port structure.
8642 Added -p option. Allows port dependent processor to be specified.
8645 Initialized the new field char *Processor field to NULL in all ports
8648 Compiler generated registers for interrupt context saving
8649 were not getting allocated.
8651 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8654 Fixed left shift. Will promote the left side of a left shift
8655 if a) left shifting more than size of operand or b) when assigned
8656 to something size > size of left side
8658 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8660 tons of changes. Register allocation has been
8661 rewritten. Added customization for the various PICs. Flow
8662 analysis is restructured. ...
8668 Added. device.c is a PIC port hack to accomodate variations
8671 2002-03-13 Michael Hope <michaelh AT vroom>
8673 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8675 2002-03-04 johanknol <johanknol AT manik>
8677 * /src/SDCCval.c: fixed
8679 const unsigned char arr[][2] = { { 0, 1 } };
8680 t18.c:1: error: Initializer element is not constant
8682 2002-03-04 bela <bela AT manik>
8684 * /device/include/mcs51reg.h:
8685 ds89c420 register definition update
8687 2002-03-03 <johan AT FRIJA>
8689 * support/Util/SDCCerr.c: did something, but don't no why anymore
