1309 * device/lib/printf_tiny.c: updated comments
1311 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1313 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1316 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1318 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1319 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1321 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1323 * device/lib/printf_large.c: removed inline assembly for portability and
1324 readability. Use printf_fast if speed or size are more important.
1325 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1326 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1328 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1330 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1331 prevent compiler warning
1333 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1335 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1336 moved to level 0 and declared as static. Also they are explicit
1337 placed in access bank. This was necessery because some times they
1338 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1339 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1340 optimizations. Currently only compare to unsigned char is implemented,
1341 * src/pic16/gen.c: added fReturnIdx array,
1342 * (struct resolvedIfx) is moved to gen.h and made public,
1343 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1344 * (aopForSym): added an optimization to directly store in stack of
1345 the operand of a SEND iCode,
1346 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1347 but as registers instead (AOP_REG) using the fReturnIdx array,
1348 * (pic16_freeAsmop): remove the freed register from the
1349 _G.sregsAlloc field,
1350 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1351 a compare of 'WREG',
1352 * (pic16_popGetTempRegCond): changed function prototype, now
1353 function takes also a bitVector argument v which holds the current
1354 set of registers that are allocated for stack access by aopForSym,
1355 registers allocated in aopForSym for accessing stack symbols are not
1356 any more part of the functions usedRegs field,
1357 * (genCall): some times aopOp is called for a stack variable to be
1358 send, aopForSym might perform the push, if this is true make sure
1359 that genCall doesn't push the variable twice by testing _G.resDirect,
1360 * (genFunction): changed testing for unspecified interrupt number
1361 from 256 to INTNO_UNSPEC,
1362 * modified selection scheme of frame pointer generation. Previously
1363 if function did use local registers a frame pointer was generated,
1364 now a frame pointer is generated only if function has arguments
1365 (that need PLUSW2 register access), or has stack arguments, or the
1366 compiler is not instructed to omit the frame pointer,
1367 * (genEndFunction): before restoring local registers that were saved
1368 in the function preamble, also restore the registers that *might*
1369 have been allocated for stack access,
1370 * (genRet): removed some old comments,
1371 * (genCmp, the active (RN's) version): added a call to the
1372 pic16_genCmp_special function to perform the compare with a more
1373 robust and optimized way,
1374 * (genInline): a feature has been added in inline code generation,
1375 which allows a wildcard variable substitution when writing inline
1376 assembly. Code is incomplete and experimental therefore undocumented,
1377 * (genCast): changed order of aopOp for result and right to allow
1378 aopForSym to directly load the result if possible,
1379 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1380 perform an optimized compare on some selected special occasions,
1381 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1382 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1383 generate an IVT any more,
1384 * src/pic16/main.c (pic16_optionsTable): added command line option
1386 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1387 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1389 * src/pic16/NOTES: Raphael Neider added in list of active developers
1390 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1391 jumptable_end to prevent bug #,
1392 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1393 inCond and outCond fields,
1394 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1395 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1396 turn off register spilling,
1397 * (packRegsForOneUse): synced with other ports' versions although it
1398 is not used currently,
1399 * (pic16_packRegisters): added an optimization while reading
1400 structure bitfields, some registers may be saved (malloc code is
1401 decreased by 80 bytes)
1403 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1405 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1406 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1407 this can be optimized more?
1409 2005-03-10 Raphael Neider <rneider AT web.de>
1411 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1412 genNearPointerGet): (hopefully) fixed access to bitfields via
1413 pointers (p->bitN = x; and x = p->bitN; failed)
1415 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1458 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1459 to keep the correct label reference count when adding/removing references
1460 to labels. A peephole file using this is appended to patch #1144962.

1739 access stack and frame pointers. They are initially assigned to
1740 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1741 accessing SFRs. Updated all occurences of modification of stack or
1742 frame pointer in gen.c and pcode.c,

2086 functions, ctype functions and macros and some functions of the
2087 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2088 be extensively tested in the future. Standard disclaimer here.

2103 special compare&skip instructions. Initial tests fail some times
2104 with variables grater than 1 byte in size, so new code is disabled,
2105 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2107 * (genCast): began a fix to optimize the casting of a bit to another
2108 bit, now assigning a bitfield to another bitfield will fail, sorry,

5133 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5134 loaded with the linker search paths (-L arguments) and the libraries
5135 to be linked with the current source (-l arguments). Changes
5136 currently will affect only the pic16 port.
5137 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5138 include path the port specific paths and port specific libraries,
5139 * gplink command now contains the $3 argument,
5140 * src/pic16/device.h,

5157 Documenting changes from previous commits.
5158 * configure.in (version 1.56),
5159 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5160 when generating output files to configure the pic16 library,
5161 but now I've commented it out, since gputils aren't installed in the
5162 SF compile farm, so library won't compile
5164 * device/lib/Makefile.in (version 1.56): initially I've added in
5165 target 'all' the prerequestive 'model-pic16' so it compiled the
5166 pic16 library, but now I've commented it out for the same reasons
5168 * added targets 'model-pic16' and 'objects-pic16' to compile the
5170 * added target 'port-specific-objects-pic16' to handle the
5171 generated libraries and copy them into the build/ directory
5172 * added target 'clean-intermediate-pic16' to clean intermediate
5173 files into pic16 directory
5174 * in target 'installdirs' added line to create directory pic16 in
5175 the installation path

5178 added lines to copy all header files to installation path,
5179 * in target 'installdirs' added line create directory for pic16
5180 headers in the installation path

5196 option so that it actually works. Made it specific to the z80, since
5197 the gbz80 doesn't have these kinds of I/O ports.
5199 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5225 via literal number. The symbol is placed in the corresponding
5226 position of the data ram
5227 * (pic16_dump_section): relocatable and absolute uninitialized
5228 data are now emitted in sorted order to reduce section naming,
5229 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5230 weren't marked as being in the access bank,

5308 UPPER for immediate operands,
5309 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5311 * src/pic16/peeph.def: all peepholes with movff are commented out,
5312 because there is a problem in the pcode peep optimizer,
5313 * src/pic16/ralloc.c: the register allocator can now reuse local
5314 function symbols for another function. This saves register usage.
5315 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5317 Added file src/pic16/NOTES with information about program writing on

5423 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5425 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5426 (default behaviour).
5428 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5430 A python script to validate compiler diagnostic messages. It can be
5431 used to verify that sdcc complains about bad c source code and
5432 gives a good location of the error.
5433 * support/valdiag/Makefile,
5434 * support/valdiag/valdiag.py,

5454 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5456 * sdcc.spec: updated
5457 * device/include/Makefile.in: don't install CVS directories
5458 * device/lib/Makefile.in: added removal of CVS directories after install
5459 * doc/Makefile: fixed install, added local_icons
5460 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

5465 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5467 PIC16 port related changes:
5468 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5469 added variable stackPos,
5471 * gen.c: genCall, assignResultValue: added support for
5472 pushing/retrieving function parameters to/from stack,
5473 genFunction,genEndFunction: setup stack frame for the
5475 genAddrOf: will be changed according to bug 863624
5477 * added files genutils.c and genutils.h which contain gen*
5478 debugged and optimised functions extracted from gen.c
5480 * glue.c: added variable 'externs' which holds extern symbols,
5481 pic16emitRegularMap: is modified to properly handle relocatable
5482 symbols under the new scheme,
5483 pic16createInterruptVect: is modified
5484 pic16printPublics: is modified to emit 'global' assembler directives,
5485 added pic16_printExterns to print extern symbols,
5486 pic16glue: initializes stack/frame pointer in the beginning of
5487 the assembly output. Temporary hack, will be corrected later,
5488 because gplink yet does not support stack and SDCC does not
5489 yet support a type of crt0.o object to create the final binary.
5491 * Removed many lines that contain 8051 legacy code.
5492 * The code is finally placed under a 'code' directive.
5493 * Added port specific options.
5495 * _process_pragma: simplified since now we do not need *special*
5496 include file to define SFR registers. But a separate header
5497 will be needed. This will be developed later.
5498 * _pic16_parseOptions: added, parses port specific options:
5499 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5500 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5501 --preplace-udata-with=
5503 * _pic16_setDefaultOptions: modified to initialize section names,
5504 but hack is temporarly out of order since it needs improvement.
5505 * _pic16_genAssemblerPreamble: configuration words are emitted by
5506 their address instead of their name. This part is incomplete and
5507 supports only the 18Fxx2 devices. Other devices will emit an error
5508 during assembly since they do not contain the same set of config
5510 * _pic16_genIVT: is modified,
5512 * pcode.c: added definitions for some hardware registers that are needed
5514 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5515 All PCI entries are updated. Now LFSR is supported.
5516 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5517 * added pic16_newpCodeOpLit2 to support instructions with
5518 two literal arguments
5519 * pic16_pCode2str: corrected code that emits assembler instructions
5520 with two literal operands and those that have an access bit modifier
5521 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5522 this fixes a bug which caused some labels to be lost, when an
5523 assembler directive was added, i.e. banksel,
5524 * pic16_FixRegisterBanking: improved logic that causes the insertion
5526 * InlineFunction: functions that are called once, are not any more
5527 inlined. This can be a port option in the future,
5529 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5531 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5532 hold the corresponding uninitialized symbols,
5533 * pic16_allocProcessorRegister: registers have explicit marked the
5535 * pic16_allocInternalRegister: registers are explicit marked as
5537 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5538 processing list, so bit registers were lost,
5541 * ralloc.h: added field 'accessBank' and original symbol operand
5542 in register definition,
5543 * removed the field isMapped from register definition,
5545 ** Several functions have been removed from various sources:
5546 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5547 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5548 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5549 pic16_assignRelocatableRegisters
5551 ** others have been introduced:
5552 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5553 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5555 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5557 * support/scripts/inc2h.pl: changed definition of BIT_AT
5558 to emit 'sbit at' instead of 'bit at'. This was a request.
5560 PIC16 port related preliminary changes:
5561 * gen.c: prefixed function popRegFromString with
5562 pic16_ and all references to it corrected
5563 * pcode.c: all pic16_pc_* hardware registers prefixed
5564 with underscore (_),
5565 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5566 * ralloc.c: newReg(): when register is REG_SFR then
5567 set address to rIdx,
5568 pic16_allocProcessorRegister(): marks register wasUsed=0
5569 pic16_writeUsedRegs(): added a call to assign processor
5570 registers via pic16_assignFixedRegisters
5572 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5574 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5575 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5576 variables in unused register banks. Also the SSEG is placed
5577 wherever there is enough space for it, and IDATA can be anywhere
5578 in internal RAM. For now compile using -Wl-Y[stack_size].
5579 The mem file is different for this option as well, since it
5580 makes no sense of talking about DSEG lenght.
5582 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5584 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5585 in certain cases, e.g. when ROM assignment, patch provided
5586 from Albert den Haan.
5588 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6474 support for standard C idiom of memory mapped variables; for
6475 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6476 to xdata int at 0x1234 tempvar = 1.
6477 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6478 provided by Akiya ISHIDA

6590 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6591 fetching of the pointer
6592 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6593 copied from genNearPointerSet()
6594 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6595 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6609 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6611 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6612 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6613 type for bits was changed. It resulted in bit variables becoming
6614 global, which is not permitted in PIC 14 assembly output.
6616 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6631 A few small changes that speed up the peephole optimizer.
6635 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6637 Try to make the peephole optimizer smarter by maintaining
6638 an association between the assembly source code and the
6639 iCodes that originated them. Put this information to use
6640 with a new peephole rule condition "notVolatile" so that
6641 the rules can be aggressive yet still safe.
6646 * src/mcs51/peeph.def
6648 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6652 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6653 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6654 if the left or right operand symbols have the accuse flag set.
6656 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6658 Changed the type of the result of the ! (NOT) operator to char;
6659 previously it returned the same type as the source. This allows
6660 us to eliminate all the genFloatNot functions (all of its target
6661 implementations were very buggy) since !float can use the same

6673 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6674 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6675 during interrupts. Ensure WSAVE is located at a shared bank address.
6676 2. Fixed page selection in some places
6677 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6678 the registers name strings.
6679 4. Fixed "signed / unsigned compare" compiler warnings.
6680 5. The PIC port manages its own allocation of the general purpose
6681 registers, but makes no attempt to reuse them. As a result when
6682 compiling it soon runs out of general purpose registers. Some
6683 additional code was added to the files pcode.c and device.c to walk
6684 through the function call tree and rename the registers so that they
6694 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6701 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6703 Made bitfield a distinct type from bit so that bitfields
6704 convert as per ANSI C and bits retain their traditional
6705 boolean style behaviour. Implemented bitfield support in
6713 * src/ds390/gen.c: bit v bitfield split
6714 * src/z80/gen.c: New support for bitfields
6715 * support/regression/tests/bitfields.c: reenabled z80,
6718 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6720 Rules 246.x, 247.x relate to bitfields, the others speed up
6721 access to xdata mapped I/O devices.
6723 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6725 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6727 Cleaned up genPackBits and genUnpackBits and added two helper
6728 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6729 for literal assignments in genPackBits (thanks to Frieder for
6735 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6737 Fixed bug #748310 (pointer to function type mishandled when the
6738 function name is omitted). Also fixed a SIGSEGV when a function
6739 attribute (reentrant, etc) is used on a non-function or on a
6740 function but misplaced before the parameter list.
6742 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6744 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6745 * support/Util/SDCCerr.h,

6767 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6769 Made the constant following the "interrupt" keyword optional. If
6770 omitted, the function will not automatically be given an entry
6771 in the interrupt vector table (similar to #pragma NOIV, but
6772 less syntacticly kludgy). The interrupt number is also now
6773 range checked. Also fixed a bug in the high order bit example

7303 added if/endif conditional macros to remove options help
7304 messages from optionsTable when a port is not configured, added
7305 support for the PIc16 port in the ports table, when executing
7306 the compiler with no port specified on command line, a default
7307 port is selected with the new macro DEFAULT_PORT which is
7308 defined in port.h, in setDefaultOptions() linkOptions is removed
7309 from initialization assignment, since now it is a set,
7310 parseCmdLine uses setParseWithComma for linkOptions, in
7311 linkEdit() linkOptions are accessed with new function indexSet()
7312 which returns the i'th item of a set variable. See SDCCset.c, in
7313 linkEdit() when calling buildCmdLine(), added linkOptions as
7314 last argument. Now users can pass arguments to gplink via the
7315 -Wl option, main() uses pic16glue() to glue up pic16 programs

7328 * src/pic16/main.c: __config directives are commented out to stop
7329 gpasm complaining and test the linkage with gplink, _linkCmd and
7330 _asmCmd changed to be more gplink and gpasm friendly
7331 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7332 produced an error when parsed, peep rule 12 is added to utilize
7333 movff, but it is commented out since the pCode does not support
7334 yet a command with 2 address arguments
7336 2003-05-18 <johan AT balder>
7338 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8377 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8379 2003-01-04 <johan AT balder>
8381 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8383 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8396 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8397 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8399 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8401 * in \sdcc\as\mcs51\ changed these files in order to create an
8402 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8403 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8404 following files to include the previous two files: aslink.dsp,
8405 Makefile.aslink, Makefile.bcc, and Makefile.in.
8407 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8408 .adb instead of .cdb
8410 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8412 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8413 value from option --iram-size.
8415 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8417 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8420 2002-09-18 <wiml AT hhhh.org>
8422 * SDCClrange.h: exposed setFromRange() and setToRange()
8423 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8424 packRegsForAccUse() (bug 542397)
8425 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8426 multiple times and emitting the fetch operations more than once
8427 added aopGetUsesAcc() function to allow binary operators to
8428 fetch their operands in the correct order; made genMinus() emit
8429 compact code for X = LITERAL - Y
8431 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8432 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8433 sprintf() in line 1267.
8435 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8436 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8439 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8440 Changes to aslink (All the changes are marked with 'JCF'):
8442 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8445 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8446 area BSEG. Also moves, if possible, the DATA area down into the internal
8447 ram so more space is available.
8449 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8452 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8453 not bytes. Function summary() which creates a memory usage summary
8454 file with extension .mem. Reports of overlaping stack and small stack
8455 size. If the space for the stack is less than 16 bytes aslink trows a
8458 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8459 the 8051. Option 'y' for memory summary output file.
8461 Changes to sdcc (All the changes are marked with 'JCF'):
8463 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8465 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8466 overlaying area for it (uses RegBankUsed[4]).
8468 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8469 bank zero as used by default. By default aslink locates the stack
8470 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8471 the creation of the .mem file. Delegates the allocation of data area
8472 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8473 the begining of the stack area to aslink.
8475 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8476 glue() in SDCCglue.c creates an area for it.
8478 2002-09-03 Borut Razem <borut.razem AT siol.net>
8479 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8480 sdcc/src/pic/glue.c:
8481 introduced atexit() handler for teporay files removal in case of
8482 errors, assertions, ...
8484 2002-08-29 Borut Razem <borut.razem AT siol.net>
8485 * sdcc/support/cpp2/auto-host_vc_in.h:
8486 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8487 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8488 Maybe there is a similar problem with BORLANDC? It should be checked!
8490 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8491 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8492 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8493 was not executed, and the compiler (cl) launched a warning:
8494 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8496 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8497 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8499 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8500 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8502 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8503 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8504 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8505 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8506 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8507 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8508 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8509 - added Release configuration in VS projects
8510 - review of compiler an linker options
8511 - VC .exe files are generated in bin_vc directory, not to interfere
8512 with binaries generated from other projects (cygwin, mingw, bcc ...)
8514 * sdcc/src/yacc.dsp: added
8516 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8517 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8518 and insert the version number definitions from .version
8520 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8522 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8523 added - genarate auto-host.h using auto-host_vc_in.h as template
8526 removed from CVS, generated automatically
8528 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8529 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8531 2002-08-11 Borut Razem <borut.razem AT siol.net>
8532 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8534 2002-08-10 Borut Razem <borut.razem AT siol.net>
8535 * src/SDCCmain.c (main):
8536 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8537 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8538 The consequence was that some temporary files were not removed.
8541 unification of code in functions tempfilename() and tempfile():
8542 function tempnam() is defined in Visual Studio 6.0 and .NET
8544 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8546 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8547 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8548 - removed compiler command line option /WX: Treats all warnings as errors
8549 - update a list of source files, included into the project
8551 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8552 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8553 changed project type to Generic Project so that can be correcly converted to VS.NET project
8555 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8557 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8559 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8561 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8562 added return 0 statements after assert() to make compiler happy
8564 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8565 added newline in the def file to keep MSC compiler satisfied
8567 * sdcc/src/z80/gen.c:
8568 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8569 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8570 - solved MSC error in function aopDump()
8572 * sdcc_vc.h: define PREFIX as "\\sdcc"
8574 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8575 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8577 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8578 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8579 - Rewrote the register banking algorithm.
8580 - Added pCode live-range analysis to registers (for now, only non-used and
8581 singly-used registers optimized away)
8583 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8585 * 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.

8614 2002-03-28 Johan Knol <johan AT balder>
8616 * src/SDCCval.c: fixed bug #532436
8618 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8620 Added "char *Processor" field to the port structure.
8623 Added -p option. Allows port dependent processor to be specified.
8626 Initialized the new field char *Processor field to NULL in all ports
8629 Compiler generated registers for interrupt context saving
8630 were not getting allocated.
8632 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8635 Fixed left shift. Will promote the left side of a left shift
8636 if a) left shifting more than size of operand or b) when assigned
8637 to something size > size of left side
8639 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8641 tons of changes. Register allocation has been
8642 rewritten. Added customization for the various PICs. Flow
8643 analysis is restructured. ...
8649 Added. device.c is a PIC port hack to accomodate variations
8652 2002-03-13 Michael Hope <michaelh AT vroom>
8654 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8656 2002-03-04 johanknol <johanknol AT manik>
