1298 mostly missing, but it's a start.
1299 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1300 reserved identifier "__data".
1302 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1346 immedDom() returning wrong block; probably fixes bug #1160833)
1348 2005-03-20 Borut Razem <borut.razem AT siol.net>
1350 * support/scripts/inc2h.pl: WIN32 port
1352 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1354 * device/lib/makefile.in: added abs.c and labs.c
1356 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1358 * device/include/stdint.h: added
1359 * device/lib/abs.c: added
1360 * device/lib/labs.c: added
1361 * device/include/stdlib.h: added abs() and labs() prototypes

1368 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1370 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

1376 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1378 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1380 * device/lib/printf_large.c: removed inline assembly for portability and
1381 readability. Use printf_fast if speed or size are more important.
1382 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1383 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1385 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1387 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1388 prevent compiler warning
1390 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1392 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1393 moved to level 0 and declared as static. Also they are explicit
1394 placed in access bank. This was necessery because some times they
1395 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1396 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1397 optimizations. Currently only compare to unsigned char is implemented,
1398 * src/pic16/gen.c: added fReturnIdx array,
1399 * (struct resolvedIfx) is moved to gen.h and made public,
1400 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1401 * (aopForSym): added an optimization to directly store in stack of
1402 the operand of a SEND iCode,
1403 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1404 but as registers instead (AOP_REG) using the fReturnIdx array,
1405 * (pic16_freeAsmop): remove the freed register from the
1406 _G.sregsAlloc field,
1407 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1408 a compare of 'WREG',
1409 * (pic16_popGetTempRegCond): changed function prototype, now
1410 function takes also a bitVector argument v which holds the current
1411 set of registers that are allocated for stack access by aopForSym,
1412 registers allocated in aopForSym for accessing stack symbols are not
1413 any more part of the functions usedRegs field,
1414 * (genCall): some times aopOp is called for a stack variable to be
1415 send, aopForSym might perform the push, if this is true make sure
1416 that genCall doesn't push the variable twice by testing _G.resDirect,
1417 * (genFunction): changed testing for unspecified interrupt number
1418 from 256 to INTNO_UNSPEC,
1419 * modified selection scheme of frame pointer generation. Previously
1420 if function did use local registers a frame pointer was generated,
1421 now a frame pointer is generated only if function has arguments
1422 (that need PLUSW2 register access), or has stack arguments, or the
1423 compiler is not instructed to omit the frame pointer,
1424 * (genEndFunction): before restoring local registers that were saved
1425 in the function preamble, also restore the registers that *might*
1426 have been allocated for stack access,
1427 * (genRet): removed some old comments,
1428 * (genCmp, the active (RN's) version): added a call to the
1429 pic16_genCmp_special function to perform the compare with a more
1430 robust and optimized way,
1431 * (genInline): a feature has been added in inline code generation,
1432 which allows a wildcard variable substitution when writing inline
1433 assembly. Code is incomplete and experimental therefore undocumented,
1434 * (genCast): changed order of aopOp for result and right to allow
1435 aopForSym to directly load the result if possible,
1436 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1437 perform an optimized compare on some selected special occasions,
1438 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1439 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1440 generate an IVT any more,
1441 * src/pic16/main.c (pic16_optionsTable): added command line option
1443 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1444 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1446 * src/pic16/NOTES: Raphael Neider added in list of active developers
1447 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1448 jumptable_end to prevent bug #,
1449 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1450 inCond and outCond fields,
1451 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1452 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1453 turn off register spilling,
1454 * (packRegsForOneUse): synced with other ports' versions although it
1455 is not used currently,
1456 * (pic16_packRegisters): added an optimization while reading
1457 structure bitfields, some registers may be saved (malloc code is
1458 decreased by 80 bytes)
1460 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1462 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1463 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1464 this can be optimized more?
1466 2005-03-10 Raphael Neider <rneider AT web.de>
1468 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1469 genNearPointerGet): (hopefully) fixed access to bitfields via
1470 pointers (p->bitN = x; and x = p->bitN; failed)
1472 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2105 generated for switch statements. For now you need to set the
2106 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2107 Now 4 algorithms for mcs51 jumptable generation are used:
2108 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2109 addresses loaded pc-relative for up to 112 cases and stack-pushing
2110 target addresses loaded with offset from dptr for up to 256 cases.

2140 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2142 * added libc directory. The current version of LibC contains string
2143 functions, ctype functions and macros and some functions of the
2144 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2145 be extensively tested in the future. Standard disclaimer here.
2146 Library is not automatically build yet. But one can build it by
2147 invoking 'make' inside the libc directory.
2148 * added ADC library under libio. Preliminary version yet.

2157 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2158 * (pic16_storeForReturn): optimized return of 0,
2159 * (genCmp): experimental code for new genCmp which uses PIC18's
2160 special compare&skip instructions. Initial tests fail some times
2161 with variables grater than 1 byte in size, so new code is disabled,
2162 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2164 * (genCast): began a fix to optimize the casting of a bit to another
2165 bit, now assigning a bitfield to another bitfield will fail, sorry,

5188 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5190 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5191 loaded with the linker search paths (-L arguments) and the libraries
5192 to be linked with the current source (-l arguments). Changes
5193 currently will affect only the pic16 port.
5194 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5195 include path the port specific paths and port specific libraries,
5196 * gplink command now contains the $3 argument,
5197 * src/pic16/device.h,
5198 * src/pic16/device.c,: structure PIC_device is made public and
5199 renamed to PIC16_device, the same for variable Pics which is renamed

5214 Documenting changes from previous commits.
5215 * configure.in (version 1.56),
5216 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5217 when generating output files to configure the pic16 library,
5218 but now I've commented it out, since gputils aren't installed in the
5219 SF compile farm, so library won't compile
5221 * device/lib/Makefile.in (version 1.56): initially I've added in
5222 target 'all' the prerequestive 'model-pic16' so it compiled the
5223 pic16 library, but now I've commented it out for the same reasons
5225 * added targets 'model-pic16' and 'objects-pic16' to compile the
5227 * added target 'port-specific-objects-pic16' to handle the
5228 generated libraries and copy them into the build/ directory
5229 * added target 'clean-intermediate-pic16' to clean intermediate
5230 files into pic16 directory
5231 * in target 'installdirs' added line to create directory pic16 in
5232 the installation path
5234 * device/include/Makefile.in (version 1.11): in target 'install'
5235 added lines to copy all header files to installation path,
5236 * in target 'installdirs' added line create directory for pic16
5237 headers in the installation path

5252 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5253 option so that it actually works. Made it specific to the z80, since
5254 the gbz80 doesn't have these kinds of I/O ports.
5256 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5258 * device/include/z180.h,

5287 weren't marked as being in the access bank,
5289 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5291 Added portion of GNU PIC Library under the directory
5292 device/include/pic16 and device/lib/pic16. These files
5293 contain the declarations of SFRs for the PIC18Fxx2 devices.
5294 The directory is initialized via configure from toplevel.
5296 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5324 all over. Telling LaTeX to be less strict with word spacing
5325 to better keep the right margin. Changed some notes about
5326 maintainance of the ports in section 3.2.1 - is it OK like this?
5328 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5368 * src/pic16/peeph.def: all peepholes with movff are commented out,
5369 because there is a problem in the pcode peep optimizer,
5370 * src/pic16/ralloc.c: the register allocator can now reuse local

5447 2004-01-07 Borut Razem <borut.razem AT siol.net>
5449 * support/scripts/sdcc.nsi: update PATH
5450 * support/scripts/sdcc.ico: craeted

5463 include information about variables allocated to the overlay
5466 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5468 * as/mcs51/lkmain.c: Help about -Y option

5480 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5482 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5483 (default behaviour).
5485 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5487 A python script to validate compiler diagnostic messages. It can be
5488 used to verify that sdcc complains about bad c source code and
5489 gives a good location of the error.
5490 * support/valdiag/Makefile,
5491 * support/valdiag/valdiag.py,
5492 * support/valdiag/tests/*
5494 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5507 * src/common.h: added ifndef/define/endif macros
5508 around the header file.
5509 Bug reported from Jesus Calvino-Fraga
5511 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5513 * sdcc.spec: updated
5514 * device/include/Makefile.in: don't install CVS directories
5515 * device/lib/Makefile.in: added removal of CVS directories after install
5516 * doc/Makefile: fixed install, added local_icons
5517 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5518 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5519 * src/ds390/gen.c (genRightShift): fixed bug #870788
5520 * src/SDCCast.c (decorateType): fixed bug #870781
5522 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5524 PIC16 port related changes:
5525 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5526 added variable stackPos,
5528 * gen.c: genCall, assignResultValue: added support for
5529 pushing/retrieving function parameters to/from stack,
5530 genFunction,genEndFunction: setup stack frame for the
5532 genAddrOf: will be changed according to bug 863624
5534 * added files genutils.c and genutils.h which contain gen*
5535 debugged and optimised functions extracted from gen.c
5537 * glue.c: added variable 'externs' which holds extern symbols,
5538 pic16emitRegularMap: is modified to properly handle relocatable
5539 symbols under the new scheme,
5540 pic16createInterruptVect: is modified
5541 pic16printPublics: is modified to emit 'global' assembler directives,
5542 added pic16_printExterns to print extern symbols,
5543 pic16glue: initializes stack/frame pointer in the beginning of
5544 the assembly output. Temporary hack, will be corrected later,
5545 because gplink yet does not support stack and SDCC does not
5546 yet support a type of crt0.o object to create the final binary.
5548 * Removed many lines that contain 8051 legacy code.
5549 * The code is finally placed under a 'code' directive.
5550 * Added port specific options.
5552 * _process_pragma: simplified since now we do not need *special*
5553 include file to define SFR registers. But a separate header
5554 will be needed. This will be developed later.
5555 * _pic16_parseOptions: added, parses port specific options:
5556 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5557 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5558 --preplace-udata-with=
5560 * _pic16_setDefaultOptions: modified to initialize section names,
5561 but hack is temporarly out of order since it needs improvement.
5562 * _pic16_genAssemblerPreamble: configuration words are emitted by
5563 their address instead of their name. This part is incomplete and
5564 supports only the 18Fxx2 devices. Other devices will emit an error
5565 during assembly since they do not contain the same set of config
5567 * _pic16_genIVT: is modified,
5569 * pcode.c: added definitions for some hardware registers that are needed
5571 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5572 All PCI entries are updated. Now LFSR is supported.
5573 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5574 * added pic16_newpCodeOpLit2 to support instructions with
5575 two literal arguments
5576 * pic16_pCode2str: corrected code that emits assembler instructions
5577 with two literal operands and those that have an access bit modifier
5578 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5579 this fixes a bug which caused some labels to be lost, when an
5580 assembler directive was added, i.e. banksel,
5581 * pic16_FixRegisterBanking: improved logic that causes the insertion
5583 * InlineFunction: functions that are called once, are not any more
5584 inlined. This can be a port option in the future,
5586 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5588 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5589 hold the corresponding uninitialized symbols,
5590 * pic16_allocProcessorRegister: registers have explicit marked the
5592 * pic16_allocInternalRegister: registers are explicit marked as
5594 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5595 processing list, so bit registers were lost,
5598 * ralloc.h: added field 'accessBank' and original symbol operand
5599 in register definition,
5600 * removed the field isMapped from register definition,
5602 ** Several functions have been removed from various sources:
5603 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5604 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5605 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5606 pic16_assignRelocatableRegisters
5608 ** others have been introduced:
5609 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5610 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5612 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5614 * support/scripts/inc2h.pl: changed definition of BIT_AT
5615 to emit 'sbit at' instead of 'bit at'. This was a request.
5617 PIC16 port related preliminary changes:
5618 * gen.c: prefixed function popRegFromString with
5619 pic16_ and all references to it corrected
5620 * pcode.c: all pic16_pc_* hardware registers prefixed
5621 with underscore (_),
5622 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5623 * ralloc.c: newReg(): when register is REG_SFR then
5624 set address to rIdx,
5625 pic16_allocProcessorRegister(): marks register wasUsed=0
5626 pic16_writeUsedRegs(): added a call to assign processor
5627 registers via pic16_assignFixedRegisters
5629 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5631 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5632 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5633 variables in unused register banks. Also the SSEG is placed
5634 wherever there is enough space for it, and IDATA can be anywhere
5635 in internal RAM. For now compile using -Wl-Y[stack_size].
5636 The mem file is different for this option as well, since it
5637 makes no sense of talking about DSEG lenght.
5639 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5641 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5642 in certain cases, e.g. when ROM assignment, patch provided
5643 from Albert den Haan.
5645 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5791 without the non-interrupt code having to disable interrupts)
5793 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5795 * src/SDCCicode.c (geniCodeAdd),

5888 it breaks with bitfields, extern declarations, and gcse analysis.
5889 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5890 could be assigned through a pointer, so don't complain.

6668 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6669 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6670 type for bits was changed. It resulted in bit variables becoming
6671 global, which is not permitted in PIC 14 assembly output.

6688 A few small changes that speed up the peephole optimizer.
6692 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6694 Try to make the peephole optimizer smarter by maintaining
6695 an association between the assembly source code and the
6696 iCodes that originated them. Put this information to use
6697 with a new peephole rule condition "notVolatile" so that
6698 the rules can be aggressive yet still safe.
6703 * src/mcs51/peeph.def
6705 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6709 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6710 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6711 if the left or right operand symbols have the accuse flag set.
6713 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6715 Changed the type of the result of the ! (NOT) operator to char;
6716 previously it returned the same type as the source. This allows
6717 us to eliminate all the genFloatNot functions (all of its target
6718 implementations were very buggy) since !float can use the same
6721 * src/SDCCicode.c (ast2iCode): ! returns char

6730 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6731 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6732 during interrupts. Ensure WSAVE is located at a shared bank address.
6733 2. Fixed page selection in some places
6734 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6735 the registers name strings.
6736 4. Fixed "signed / unsigned compare" compiler warnings.
6737 5. The PIC port manages its own allocation of the general purpose
6738 registers, but makes no attempt to reuse them. As a result when
6739 compiling it soon runs out of general purpose registers. Some
6740 additional code was added to the files pcode.c and device.c to walk
6741 through the function call tree and rename the registers so that they
6751 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6752 genPlus() & genMinus() when the result is the same as left or right

6758 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6760 Made bitfield a distinct type from bit so that bitfields
6761 convert as per ANSI C and bits retain their traditional
6762 boolean style behaviour. Implemented bitfield support in
6770 * src/ds390/gen.c: bit v bitfield split
6771 * src/z80/gen.c: New support for bitfields
6772 * support/regression/tests/bitfields.c: reenabled z80,
6775 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6777 Rules 246.x, 247.x relate to bitfields, the others speed up
6778 access to xdata mapped I/O devices.
6780 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6782 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6784 Cleaned up genPackBits and genUnpackBits and added two helper
6785 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6786 for literal assignments in genPackBits (thanks to Frieder for
6792 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6794 Fixed bug #748310 (pointer to function type mishandled when the
6795 function name is omitted). Also fixed a SIGSEGV when a function
6796 attribute (reentrant, etc) is used on a non-function or on a

6827 omitted, the function will not automatically be given an entry
6828 in the interrupt vector table (similar to #pragma NOIV, but

7366 from initialization assignment, since now it is a set,
7367 parseCmdLine uses setParseWithComma for linkOptions, in
7368 linkEdit() linkOptions are accessed with new function indexSet()
7369 which returns the i'th item of a set variable. See SDCCset.c, in
7370 linkEdit() when calling buildCmdLine(), added linkOptions as
7371 last argument. Now users can pass arguments to gplink via the
7372 -Wl option, main() uses pic16glue() to glue up pic16 programs

7386 gpasm complaining and test the linkage with gplink, _linkCmd and
7387 _asmCmd changed to be more gplink and gpasm friendly
7388 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7389 produced an error when parsed, peep rule 12 is added to utilize
7390 movff, but it is commented out since the pCode does not support
7391 yet a command with 2 address arguments

8430 * src/SDCCicode.c: fixed array add
8432 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8433 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8434 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8436 2003-01-04 <johan AT balder>
8438 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8440 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8441 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8443 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8444 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8453 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8454 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8456 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8458 * in \sdcc\as\mcs51\ changed these files in order to create an
8459 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8460 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8461 following files to include the previous two files: aslink.dsp,
8462 Makefile.aslink, Makefile.bcc, and Makefile.in.
8464 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8465 .adb instead of .cdb
8467 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8469 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8470 value from option --iram-size.
8472 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8474 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8477 2002-09-18 <wiml AT hhhh.org>
8479 * SDCClrange.h: exposed setFromRange() and setToRange()
8480 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8481 packRegsForAccUse() (bug 542397)
8482 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8483 multiple times and emitting the fetch operations more than once
8484 added aopGetUsesAcc() function to allow binary operators to
8485 fetch their operands in the correct order; made genMinus() emit
8486 compact code for X = LITERAL - Y
8488 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8489 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8490 sprintf() in line 1267.
8492 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8493 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8496 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8497 Changes to aslink (All the changes are marked with 'JCF'):
8499 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8502 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8503 area BSEG. Also moves, if possible, the DATA area down into the internal
8504 ram so more space is available.
8506 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8509 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8510 not bytes. Function summary() which creates a memory usage summary
8511 file with extension .mem. Reports of overlaping stack and small stack
8512 size. If the space for the stack is less than 16 bytes aslink trows a
8515 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8516 the 8051. Option 'y' for memory summary output file.
8518 Changes to sdcc (All the changes are marked with 'JCF'):
8520 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8522 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8523 overlaying area for it (uses RegBankUsed[4]).
8525 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8526 bank zero as used by default. By default aslink locates the stack
8527 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8528 the creation of the .mem file. Delegates the allocation of data area
8529 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8530 the begining of the stack area to aslink.
8532 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8533 glue() in SDCCglue.c creates an area for it.
8535 2002-09-03 Borut Razem <borut.razem AT siol.net>
8536 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8537 sdcc/src/pic/glue.c:
8538 introduced atexit() handler for teporay files removal in case of
8539 errors, assertions, ...
8541 2002-08-29 Borut Razem <borut.razem AT siol.net>
8542 * sdcc/support/cpp2/auto-host_vc_in.h:
8543 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8544 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8545 Maybe there is a similar problem with BORLANDC? It should be checked!
8547 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8548 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8549 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8550 was not executed, and the compiler (cl) launched a warning:
8551 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8553 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8554 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8556 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8557 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8559 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8560 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8561 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8562 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8563 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8564 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8565 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8566 - added Release configuration in VS projects
8567 - review of compiler an linker options
8568 - VC .exe files are generated in bin_vc directory, not to interfere
8569 with binaries generated from other projects (cygwin, mingw, bcc ...)
8571 * sdcc/src/yacc.dsp: added
8573 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8574 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8575 and insert the version number definitions from .version
8577 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8579 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8580 added - genarate auto-host.h using auto-host_vc_in.h as template
8583 removed from CVS, generated automatically
8585 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8586 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8588 2002-08-11 Borut Razem <borut.razem AT siol.net>
8589 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8591 2002-08-10 Borut Razem <borut.razem AT siol.net>
8592 * src/SDCCmain.c (main):
8593 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8594 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8595 The consequence was that some temporary files were not removed.
8598 unification of code in functions tempfilename() and tempfile():
8599 function tempnam() is defined in Visual Studio 6.0 and .NET
8601 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8603 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8604 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8605 - removed compiler command line option /WX: Treats all warnings as errors
8606 - update a list of source files, included into the project
8608 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8609 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8610 changed project type to Generic Project so that can be correcly converted to VS.NET project
8612 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8614 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8616 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8618 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8619 added return 0 statements after assert() to make compiler happy
8621 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8622 added newline in the def file to keep MSC compiler satisfied
8624 * sdcc/src/z80/gen.c:
8625 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8626 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8627 - solved MSC error in function aopDump()
8629 * sdcc_vc.h: define PREFIX as "\\sdcc"
8631 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8632 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8634 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8635 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8636 - Rewrote the register banking algorithm.
8637 - Added pCode live-range analysis to registers (for now, only non-used and
8638 singly-used registers optimized away)
8640 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8642 * 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.
8644 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8645 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8647 2002-04-22 Michael Hope <michaelh AT vroom>

8667 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8669 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8671 2002-03-28 Johan Knol <johan AT balder>
8673 * src/SDCCval.c: fixed bug #532436
8675 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8677 Added "char *Processor" field to the port structure.
