1313 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1314 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1316 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1318 * device/lib/printf_large.c: removed inline assembly for portability and
1319 readability. Use printf_fast if speed or size are more important.
1320 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1321 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1323 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1325 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1326 prevent compiler warning
1328 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1330 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1331 moved to level 0 and declared as static. Also they are explicit
1332 placed in access bank. This was necessery because some times they
1333 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1334 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1335 optimizations. Currently only compare to unsigned char is implemented,
1336 * src/pic16/gen.c: added fReturnIdx array,
1337 * (struct resolvedIfx) is moved to gen.h and made public,
1338 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1339 * (aopForSym): added an optimization to directly store in stack of
1340 the operand of a SEND iCode,
1341 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1342 but as registers instead (AOP_REG) using the fReturnIdx array,
1343 * (pic16_freeAsmop): remove the freed register from the
1344 _G.sregsAlloc field,
1345 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1346 a compare of 'WREG',
1347 * (pic16_popGetTempRegCond): changed function prototype, now
1348 function takes also a bitVector argument v which holds the current
1349 set of registers that are allocated for stack access by aopForSym,
1350 registers allocated in aopForSym for accessing stack symbols are not
1351 any more part of the functions usedRegs field,
1352 * (genCall): some times aopOp is called for a stack variable to be
1353 send, aopForSym might perform the push, if this is true make sure
1354 that genCall doesn't push the variable twice by testing _G.resDirect,
1355 * (genFunction): changed testing for unspecified interrupt number
1356 from 256 to INTNO_UNSPEC,
1357 * modified selection scheme of frame pointer generation. Previously
1358 if function did use local registers a frame pointer was generated,
1359 now a frame pointer is generated only if function has arguments
1360 (that need PLUSW2 register access), or has stack arguments, or the
1361 compiler is not instructed to omit the frame pointer,
1362 * (genEndFunction): before restoring local registers that were saved
1363 in the function preamble, also restore the registers that *might*
1364 have been allocated for stack access,
1365 * (genRet): removed some old comments,
1366 * (genCmp, the active (RN's) version): added a call to the
1367 pic16_genCmp_special function to perform the compare with a more
1368 robust and optimized way,
1369 * (genInline): a feature has been added in inline code generation,
1370 which allows a wildcard variable substitution when writing inline
1371 assembly. Code is incomplete and experimental therefore undocumented,
1372 * (genCast): changed order of aopOp for result and right to allow
1373 aopForSym to directly load the result if possible,
1374 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1375 perform an optimized compare on some selected special occasions,
1376 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1377 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1378 generate an IVT any more,
1379 * src/pic16/main.c (pic16_optionsTable): added command line option
1381 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1382 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1384 * src/pic16/NOTES: Raphael Neider added in list of active developers
1385 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1386 jumptable_end to prevent bug #,
1387 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1388 inCond and outCond fields,
1389 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1390 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1391 turn off register spilling,
1392 * (packRegsForOneUse): synced with other ports' versions although it
1393 is not used currently,
1394 * (pic16_packRegisters): added an optimization while reading
1395 structure bitfields, some registers may be saved (malloc code is
1396 decreased by 80 bytes)
1398 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1400 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1401 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1402 this can be optimized more?
1404 2005-03-10 Raphael Neider <rneider AT web.de>
1406 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1407 genNearPointerGet): (hopefully) fixed access to bitfields via
1408 pointers (p->bitN = x; and x = p->bitN; failed)
1410 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1734 access stack and frame pointers. They are initially assigned to
1735 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1736 accessing SFRs. Updated all occurences of modification of stack or
1737 frame pointer in gen.c and pcode.c,
1738 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
1739 assigning of a literal value to pointers,

2080 * added libc directory. The current version of LibC contains string
2081 functions, ctype functions and macros and some functions of the
2082 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2083 be extensively tested in the future. Standard disclaimer here.

2098 special compare&skip instructions. Initial tests fail some times
2099 with variables grater than 1 byte in size, so new code is disabled,
2100 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2102 * (genCast): began a fix to optimize the casting of a bit to another
2103 bit, now assigning a bitfield to another bitfield will fail, sorry,

2118 * src/pic16/ralloc.c (allocReg): add preliminary support for
2119 supporting a limited set of temporary registers,
2121 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5128 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5129 loaded with the linker search paths (-L arguments) and the libraries
5130 to be linked with the current source (-l arguments). Changes
5131 currently will affect only the pic16 port.
5132 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5133 include path the port specific paths and port specific libraries,
5134 * gplink command now contains the $3 argument,
5135 * src/pic16/device.h,

5152 Documenting changes from previous commits.
5153 * configure.in (version 1.56),
5154 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5155 when generating output files to configure the pic16 library,
5156 but now I've commented it out, since gputils aren't installed in the
5157 SF compile farm, so library won't compile
5159 * device/lib/Makefile.in (version 1.56): initially I've added in
5160 target 'all' the prerequestive 'model-pic16' so it compiled the
5161 pic16 library, but now I've commented it out for the same reasons
5163 * added targets 'model-pic16' and 'objects-pic16' to compile the
5165 * added target 'port-specific-objects-pic16' to handle the
5166 generated libraries and copy them into the build/ directory
5167 * added target 'clean-intermediate-pic16' to clean intermediate
5168 files into pic16 directory
5169 * in target 'installdirs' added line to create directory pic16 in

5173 added lines to copy all header files to installation path,
5174 * in target 'installdirs' added line create directory for pic16
5175 headers in the installation path

5191 option so that it actually works. Made it specific to the z80, since
5192 the gbz80 doesn't have these kinds of I/O ports.
5194 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5220 via literal number. The symbol is placed in the corresponding
5221 position of the data ram
5222 * (pic16_dump_section): relocatable and absolute uninitialized
5223 data are now emitted in sorted order to reduce section naming,
5224 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5225 weren't marked as being in the access bank,

5302 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5303 UPPER for immediate operands,
5304 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5306 * src/pic16/peeph.def: all peepholes with movff are commented out,
5307 because there is a problem in the pcode peep optimizer,
5308 * src/pic16/ralloc.c: the register allocator can now reuse local
5309 function symbols for another function. This saves register usage.
5310 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5312 Added file src/pic16/NOTES with information about program writing on
5313 the current port version.

5401 include information about variables allocated to the overlay
5404 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5406 * as/mcs51/lkmain.c: Help about -Y option

5416 LEFT_OP (left shift)
5418 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5420 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5421 (default behaviour).
5423 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5425 A python script to validate compiler diagnostic messages. It can be
5426 used to verify that sdcc complains about bad c source code and
5427 gives a good location of the error.
5428 * support/valdiag/Makefile,
5429 * support/valdiag/valdiag.py,
5430 * support/valdiag/tests/*
5432 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5447 Bug reported from Jesus Calvino-Fraga
5449 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5451 * sdcc.spec: updated
5452 * device/include/Makefile.in: don't install CVS directories
5453 * device/lib/Makefile.in: added removal of CVS directories after install
5454 * doc/Makefile: fixed install, added local_icons
5455 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5456 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5457 * src/ds390/gen.c (genRightShift): fixed bug #870788

5460 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5462 PIC16 port related changes:
5463 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5464 added variable stackPos,
5466 * gen.c: genCall, assignResultValue: added support for
5467 pushing/retrieving function parameters to/from stack,
5468 genFunction,genEndFunction: setup stack frame for the
5470 genAddrOf: will be changed according to bug 863624
5472 * added files genutils.c and genutils.h which contain gen*
5473 debugged and optimised functions extracted from gen.c
5475 * glue.c: added variable 'externs' which holds extern symbols,
5476 pic16emitRegularMap: is modified to properly handle relocatable
5477 symbols under the new scheme,
5478 pic16createInterruptVect: is modified
5479 pic16printPublics: is modified to emit 'global' assembler directives,
5480 added pic16_printExterns to print extern symbols,
5481 pic16glue: initializes stack/frame pointer in the beginning of
5482 the assembly output. Temporary hack, will be corrected later,
5483 because gplink yet does not support stack and SDCC does not
5484 yet support a type of crt0.o object to create the final binary.
5486 * Removed many lines that contain 8051 legacy code.
5487 * The code is finally placed under a 'code' directive.
5488 * Added port specific options.
5490 * _process_pragma: simplified since now we do not need *special*
5491 include file to define SFR registers. But a separate header
5492 will be needed. This will be developed later.
5493 * _pic16_parseOptions: added, parses port specific options:
5494 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5495 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5496 --preplace-udata-with=
5498 * _pic16_setDefaultOptions: modified to initialize section names,
5499 but hack is temporarly out of order since it needs improvement.
5500 * _pic16_genAssemblerPreamble: configuration words are emitted by
5501 their address instead of their name. This part is incomplete and
5502 supports only the 18Fxx2 devices. Other devices will emit an error
5503 during assembly since they do not contain the same set of config
5505 * _pic16_genIVT: is modified,
5507 * pcode.c: added definitions for some hardware registers that are needed
5509 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5510 All PCI entries are updated. Now LFSR is supported.
5511 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5512 * added pic16_newpCodeOpLit2 to support instructions with
5513 two literal arguments
5514 * pic16_pCode2str: corrected code that emits assembler instructions
5515 with two literal operands and those that have an access bit modifier
5516 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5517 this fixes a bug which caused some labels to be lost, when an
5518 assembler directive was added, i.e. banksel,
5519 * pic16_FixRegisterBanking: improved logic that causes the insertion
5521 * InlineFunction: functions that are called once, are not any more
5522 inlined. This can be a port option in the future,
5524 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5526 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5527 hold the corresponding uninitialized symbols,
5528 * pic16_allocProcessorRegister: registers have explicit marked the
5530 * pic16_allocInternalRegister: registers are explicit marked as
5532 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5533 processing list, so bit registers were lost,
5536 * ralloc.h: added field 'accessBank' and original symbol operand
5537 in register definition,
5538 * removed the field isMapped from register definition,
5540 ** Several functions have been removed from various sources:
5541 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5542 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5543 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5544 pic16_assignRelocatableRegisters
5546 ** others have been introduced:
5547 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5548 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5550 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5552 * support/scripts/inc2h.pl: changed definition of BIT_AT
5553 to emit 'sbit at' instead of 'bit at'. This was a request.
5555 PIC16 port related preliminary changes:
5556 * gen.c: prefixed function popRegFromString with
5557 pic16_ and all references to it corrected
5558 * pcode.c: all pic16_pc_* hardware registers prefixed
5559 with underscore (_),
5560 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5561 * ralloc.c: newReg(): when register is REG_SFR then
5562 set address to rIdx,
5563 pic16_allocProcessorRegister(): marks register wasUsed=0
5564 pic16_writeUsedRegs(): added a call to assign processor
5565 registers via pic16_assignFixedRegisters
5567 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5569 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5570 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5571 variables in unused register banks. Also the SSEG is placed
5572 wherever there is enough space for it, and IDATA can be anywhere
5573 in internal RAM. For now compile using -Wl-Y[stack_size].
5574 The mem file is different for this option as well, since it
5575 makes no sense of talking about DSEG lenght.
5577 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5579 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5580 in certain cases, e.g. when ROM assignment, patch provided
5581 from Albert den Haan.
5583 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6469 support for standard C idiom of memory mapped variables; for
6470 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6471 to xdata int at 0x1234 tempvar = 1.
6472 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6473 provided by Akiya ISHIDA

6585 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6586 fetching of the pointer
6587 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6588 copied from genNearPointerSet()
6589 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6590 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6606 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6607 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6608 type for bits was changed. It resulted in bit variables becoming
6609 global, which is not permitted in PIC 14 assembly output.

6626 A few small changes that speed up the peephole optimizer.
6630 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6632 Try to make the peephole optimizer smarter by maintaining
6633 an association between the assembly source code and the
6634 iCodes that originated them. Put this information to use
6635 with a new peephole rule condition "notVolatile" so that
6636 the rules can be aggressive yet still safe.
6641 * src/mcs51/peeph.def
6643 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6647 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6648 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6649 if the left or right operand symbols have the accuse flag set.
6651 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6653 Changed the type of the result of the ! (NOT) operator to char;
6654 previously it returned the same type as the source. This allows
6655 us to eliminate all the genFloatNot functions (all of its target
6656 implementations were very buggy) since !float can use the same

6668 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6669 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6670 during interrupts. Ensure WSAVE is located at a shared bank address.
6671 2. Fixed page selection in some places
6672 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6673 the registers name strings.
6674 4. Fixed "signed / unsigned compare" compiler warnings.
6675 5. The PIC port manages its own allocation of the general purpose
6676 registers, but makes no attempt to reuse them. As a result when
6677 compiling it soon runs out of general purpose registers. Some
6678 additional code was added to the files pcode.c and device.c to walk
6679 through the function call tree and rename the registers so that they
6689 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6696 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6698 Made bitfield a distinct type from bit so that bitfields
6699 convert as per ANSI C and bits retain their traditional
6700 boolean style behaviour. Implemented bitfield support in
6708 * src/ds390/gen.c: bit v bitfield split
6709 * src/z80/gen.c: New support for bitfields
6710 * support/regression/tests/bitfields.c: reenabled z80,
6713 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6715 Rules 246.x, 247.x relate to bitfields, the others speed up
6716 access to xdata mapped I/O devices.
6718 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6720 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6722 Cleaned up genPackBits and genUnpackBits and added two helper
6723 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6724 for literal assignments in genPackBits (thanks to Frieder for
6730 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6732 Fixed bug #748310 (pointer to function type mishandled when the
6733 function name is omitted). Also fixed a SIGSEGV when a function
6734 attribute (reentrant, etc) is used on a non-function or on a
6735 function but misplaced before the parameter list.
6737 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6739 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6740 * support/Util/SDCCerr.h,

6762 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6764 Made the constant following the "interrupt" keyword optional. If
6765 omitted, the function will not automatically be given an entry
6766 in the interrupt vector table (similar to #pragma NOIV, but
6767 less syntacticly kludgy). The interrupt number is also now
6768 range checked. Also fixed a bug in the high order bit example

7297 * src/SDCCmain.c: linkOptions is changed to set *,
7298 added if/endif conditional macros to remove options help
7299 messages from optionsTable when a port is not configured, added
7300 support for the PIc16 port in the ports table, when executing
7301 the compiler with no port specified on command line, a default
7302 port is selected with the new macro DEFAULT_PORT which is
7303 defined in port.h, in setDefaultOptions() linkOptions is removed
7304 from initialization assignment, since now it is a set,
7305 parseCmdLine uses setParseWithComma for linkOptions, in
7306 linkEdit() linkOptions are accessed with new function indexSet()
7307 which returns the i'th item of a set variable. See SDCCset.c, in
7308 linkEdit() when calling buildCmdLine(), added linkOptions as
7309 last argument. Now users can pass arguments to gplink via the
7310 -Wl option, main() uses pic16glue() to glue up pic16 programs

7323 * src/pic16/main.c: __config directives are commented out to stop
7324 gpasm complaining and test the linkage with gplink, _linkCmd and
7325 _asmCmd changed to be more gplink and gpasm friendly
7326 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7327 produced an error when parsed, peep rule 12 is added to utilize
7328 movff, but it is commented out since the pCode does not support
7329 yet a command with 2 address arguments
7331 2003-05-18 <johan AT balder>
7333 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7352 Fixed so you can set breakpoints prior to run, run does not stop
7353 on entry now. Add tbreak. Other enhancements and fixes for use
7356 2003-05-12 Borut Razem <borut.razem AT siol.net>
7358 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7360 2003-05-11 Borut Razem <borut.razem AT siol.net>
7362 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8368 * src/SDCCicode.c: fixed array add
8370 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8371 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8372 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8374 2003-01-04 <johan AT balder>
8376 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8378 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8379 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8381 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8382 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8391 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8392 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8394 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8396 * in \sdcc\as\mcs51\ changed these files in order to create an
8397 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8398 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8399 following files to include the previous two files: aslink.dsp,
8400 Makefile.aslink, Makefile.bcc, and Makefile.in.
8402 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8403 .adb instead of .cdb
8405 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8407 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8408 value from option --iram-size.
8410 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8412 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8415 2002-09-18 <wiml AT hhhh.org>
8417 * SDCClrange.h: exposed setFromRange() and setToRange()
8418 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8419 packRegsForAccUse() (bug 542397)
8420 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8421 multiple times and emitting the fetch operations more than once
8422 added aopGetUsesAcc() function to allow binary operators to
8423 fetch their operands in the correct order; made genMinus() emit
8424 compact code for X = LITERAL - Y
8426 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8427 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8428 sprintf() in line 1267.
8430 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8431 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8434 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8435 Changes to aslink (All the changes are marked with 'JCF'):
8437 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8440 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8441 area BSEG. Also moves, if possible, the DATA area down into the internal
8442 ram so more space is available.
8444 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8447 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8448 not bytes. Function summary() which creates a memory usage summary
8449 file with extension .mem. Reports of overlaping stack and small stack
8450 size. If the space for the stack is less than 16 bytes aslink trows a
8453 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8454 the 8051. Option 'y' for memory summary output file.
8456 Changes to sdcc (All the changes are marked with 'JCF'):
8458 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8460 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8461 overlaying area for it (uses RegBankUsed[4]).
8463 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8464 bank zero as used by default. By default aslink locates the stack
8465 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8466 the creation of the .mem file. Delegates the allocation of data area
8467 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8468 the begining of the stack area to aslink.
8470 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8471 glue() in SDCCglue.c creates an area for it.
8473 2002-09-03 Borut Razem <borut.razem AT siol.net>
8474 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8475 sdcc/src/pic/glue.c:
8476 introduced atexit() handler for teporay files removal in case of
8477 errors, assertions, ...
8479 2002-08-29 Borut Razem <borut.razem AT siol.net>
8480 * sdcc/support/cpp2/auto-host_vc_in.h:
8481 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8482 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8483 Maybe there is a similar problem with BORLANDC? It should be checked!
8485 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8486 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8487 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8488 was not executed, and the compiler (cl) launched a warning:
8489 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8491 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8492 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8494 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8495 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8497 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8498 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8499 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8500 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8501 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8502 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8503 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8504 - added Release configuration in VS projects
8505 - review of compiler an linker options
8506 - VC .exe files are generated in bin_vc directory, not to interfere
8507 with binaries generated from other projects (cygwin, mingw, bcc ...)
8509 * sdcc/src/yacc.dsp: added
8511 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8512 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8513 and insert the version number definitions from .version
8515 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8517 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8518 added - genarate auto-host.h using auto-host_vc_in.h as template
8521 removed from CVS, generated automatically
8523 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8524 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8526 2002-08-11 Borut Razem <borut.razem AT siol.net>
8527 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8529 2002-08-10 Borut Razem <borut.razem AT siol.net>
8530 * src/SDCCmain.c (main):
8531 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8532 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8533 The consequence was that some temporary files were not removed.
8536 unification of code in functions tempfilename() and tempfile():
8537 function tempnam() is defined in Visual Studio 6.0 and .NET
8539 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8541 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8542 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8543 - removed compiler command line option /WX: Treats all warnings as errors
8544 - update a list of source files, included into the project
8546 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8547 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8548 changed project type to Generic Project so that can be correcly converted to VS.NET project
8550 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8552 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8554 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8556 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8557 added return 0 statements after assert() to make compiler happy
8559 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8560 added newline in the def file to keep MSC compiler satisfied
8562 * sdcc/src/z80/gen.c:
8563 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8564 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8565 - solved MSC error in function aopDump()
8567 * sdcc_vc.h: define PREFIX as "\\sdcc"
8569 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8570 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8572 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8573 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8574 - Rewrote the register banking algorithm.
8575 - Added pCode live-range analysis to registers (for now, only non-used and
8576 singly-used registers optimized away)
8578 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

8609 2002-03-28 Johan Knol <johan AT balder>
8611 * src/SDCCval.c: fixed bug #532436
8613 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8615 Added "char *Processor" field to the port structure.
8618 Added -p option. Allows port dependent processor to be specified.
8621 Initialized the new field char *Processor field to NULL in all ports
8624 Compiler generated registers for interrupt context saving
8625 were not getting allocated.
8627 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8630 Fixed left shift. Will promote the left side of a left shift
8631 if a) left shifting more than size of operand or b) when assigned
8632 to something size > size of left side
8634 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8636 tons of changes. Register allocation has been
8637 rewritten. Added customization for the various PICs. Flow
8638 analysis is restructured. ...
8644 Added. device.c is a PIC port hack to accomodate variations

8744 * sdcc/src/SDCCloop.c:
8745 Previous fix was not good. basic blocks that have "break" or "return" are
8746 not really partof a loop , but live ranges used in these blocks should
8747 be live thru the entire loop, so set partOfLoop but don't add them to
