1306 * support/scripts/inc2h.pl: WIN32 port
1308 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1310 * device/lib/makefile.in: added abs.c and labs.c
1312 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1314 * device/include/stdint.h: added
1315 * device/lib/abs.c: added
1316 * device/lib/labs.c: added
1317 * device/include/stdlib.h: added abs() and labs() prototypes
1318 * device/lib/libsdcc.lib: added abs and labs
1319 * device/include/float.h,
1320 * device/lib/_fsmul.c,
1321 * device/lib/printf_fast.c,
1322 * device/lib/printf_tiny.c: updated comments
1324 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1326 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1329 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1331 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1332 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1334 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1336 * device/lib/printf_large.c: removed inline assembly for portability and
1337 readability. Use printf_fast if speed or size are more important.
1338 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1339 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1341 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1343 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1344 prevent compiler warning
1346 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1348 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1349 moved to level 0 and declared as static. Also they are explicit
1350 placed in access bank. This was necessery because some times they
1351 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1352 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1353 optimizations. Currently only compare to unsigned char is implemented,
1354 * src/pic16/gen.c: added fReturnIdx array,
1355 * (struct resolvedIfx) is moved to gen.h and made public,
1356 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1357 * (aopForSym): added an optimization to directly store in stack of
1358 the operand of a SEND iCode,
1359 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1360 but as registers instead (AOP_REG) using the fReturnIdx array,
1361 * (pic16_freeAsmop): remove the freed register from the
1362 _G.sregsAlloc field,
1363 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1364 a compare of 'WREG',
1365 * (pic16_popGetTempRegCond): changed function prototype, now
1366 function takes also a bitVector argument v which holds the current
1367 set of registers that are allocated for stack access by aopForSym,
1368 registers allocated in aopForSym for accessing stack symbols are not
1369 any more part of the functions usedRegs field,
1370 * (genCall): some times aopOp is called for a stack variable to be
1371 send, aopForSym might perform the push, if this is true make sure
1372 that genCall doesn't push the variable twice by testing _G.resDirect,
1373 * (genFunction): changed testing for unspecified interrupt number
1374 from 256 to INTNO_UNSPEC,
1375 * modified selection scheme of frame pointer generation. Previously
1376 if function did use local registers a frame pointer was generated,
1377 now a frame pointer is generated only if function has arguments
1378 (that need PLUSW2 register access), or has stack arguments, or the
1379 compiler is not instructed to omit the frame pointer,
1380 * (genEndFunction): before restoring local registers that were saved
1381 in the function preamble, also restore the registers that *might*
1382 have been allocated for stack access,
1383 * (genRet): removed some old comments,
1384 * (genCmp, the active (RN's) version): added a call to the
1385 pic16_genCmp_special function to perform the compare with a more
1386 robust and optimized way,
1387 * (genInline): a feature has been added in inline code generation,
1388 which allows a wildcard variable substitution when writing inline
1389 assembly. Code is incomplete and experimental therefore undocumented,
1390 * (genCast): changed order of aopOp for result and right to allow
1391 aopForSym to directly load the result if possible,
1392 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1393 perform an optimized compare on some selected special occasions,
1394 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1395 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1396 generate an IVT any more,
1397 * src/pic16/main.c (pic16_optionsTable): added command line option
1399 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1400 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1402 * src/pic16/NOTES: Raphael Neider added in list of active developers
1403 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1404 jumptable_end to prevent bug #,
1405 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1406 inCond and outCond fields,
1407 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1408 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1409 turn off register spilling,
1410 * (packRegsForOneUse): synced with other ports' versions although it
1411 is not used currently,
1412 * (pic16_packRegisters): added an optimization while reading
1413 structure bitfields, some registers may be saved (malloc code is
1414 decreased by 80 bytes)
1416 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1418 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1419 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1420 this can be optimized more?
1422 2005-03-10 Raphael Neider <rneider AT web.de>
1424 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1425 genNearPointerGet): (hopefully) fixed access to bitfields via
1426 pointers (p->bitN = x; and x = p->bitN; failed)
1428 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2062 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2063 Now 4 algorithms for mcs51 jumptable generation are used:
2064 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2098 * added libc directory. The current version of LibC contains string
2099 functions, ctype functions and macros and some functions of the
2100 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2101 be extensively tested in the future. Standard disclaimer here.

2116 special compare&skip instructions. Initial tests fail some times
2117 with variables grater than 1 byte in size, so new code is disabled,
2118 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2120 * (genCast): began a fix to optimize the casting of a bit to another
2121 bit, now assigning a bitfield to another bitfield will fail, sorry,

2136 * src/pic16/ralloc.c (allocReg): add preliminary support for
2137 supporting a limited set of temporary registers,
2139 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2163 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2165 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5144 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5146 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5147 loaded with the linker search paths (-L arguments) and the libraries
5148 to be linked with the current source (-l arguments). Changes
5149 currently will affect only the pic16 port.
5150 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5151 include path the port specific paths and port specific libraries,
5152 * gplink command now contains the $3 argument,
5153 * src/pic16/device.h,
5154 * src/pic16/device.c,: structure PIC_device is made public and
5155 renamed to PIC16_device, the same for variable Pics which is renamed

5170 Documenting changes from previous commits.
5171 * configure.in (version 1.56),
5172 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5173 when generating output files to configure the pic16 library,
5174 but now I've commented it out, since gputils aren't installed in the
5175 SF compile farm, so library won't compile
5177 * device/lib/Makefile.in (version 1.56): initially I've added in
5178 target 'all' the prerequestive 'model-pic16' so it compiled the
5179 pic16 library, but now I've commented it out for the same reasons
5181 * added targets 'model-pic16' and 'objects-pic16' to compile the
5183 * added target 'port-specific-objects-pic16' to handle the
5184 generated libraries and copy them into the build/ directory
5185 * added target 'clean-intermediate-pic16' to clean intermediate
5186 files into pic16 directory
5187 * in target 'installdirs' added line to create directory pic16 in
5188 the installation path
5190 * device/include/Makefile.in (version 1.11): in target 'install'
5191 added lines to copy all header files to installation path,
5192 * in target 'installdirs' added line create directory for pic16
5193 headers in the installation path

5208 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5209 option so that it actually works. Made it specific to the z80, since
5210 the gbz80 doesn't have these kinds of I/O ports.
5212 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5214 * device/include/z180.h,

5238 via literal number. The symbol is placed in the corresponding
5239 position of the data ram
5240 * (pic16_dump_section): relocatable and absolute uninitialized
5241 data are now emitted in sorted order to reduce section naming,
5242 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5243 weren't marked as being in the access bank,
5245 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5247 Added portion of GNU PIC Library under the directory
5248 device/include/pic16 and device/lib/pic16. These files
5249 contain the declarations of SFRs for the PIC18Fxx2 devices.
5250 The directory is initialized via configure from toplevel.
5252 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5280 all over. Telling LaTeX to be less strict with word spacing
5281 to better keep the right margin. Changed some notes about
5282 maintainance of the ports in section 3.2.1 - is it OK like this?

5291 PIC16 PORT specific changes:
5292 * src/pic16/device.c pic16_dump_equates() added,
5293 processor registers declared internally by the port are emitted in
5294 the translation as equates,
5295 * src/pic16/gen.c: inline code is passed unprocessed to the
5297 * (pic16_popGetLit2): fnuction modified to take second operand as

5321 UPPER for immediate operands,
5322 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5324 * src/pic16/peeph.def: all peepholes with movff are commented out,
5325 because there is a problem in the pcode peep optimizer,
5326 * src/pic16/ralloc.c: the register allocator can now reuse local

5436 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5438 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5439 (default behaviour).
5441 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5443 A python script to validate compiler diagnostic messages. It can be
5444 used to verify that sdcc complains about bad c source code and

5465 Bug reported from Jesus Calvino-Fraga
5467 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5469 * sdcc.spec: updated
5470 * device/include/Makefile.in: don't install CVS directories

5473 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5474 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5475 * src/ds390/gen.c (genRightShift): fixed bug #870788

5478 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5480 PIC16 port related changes:
5481 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5482 added variable stackPos,
5484 * gen.c: genCall, assignResultValue: added support for
5485 pushing/retrieving function parameters to/from stack,
5486 genFunction,genEndFunction: setup stack frame for the
5488 genAddrOf: will be changed according to bug 863624
5490 * added files genutils.c and genutils.h which contain gen*
5491 debugged and optimised functions extracted from gen.c
5493 * glue.c: added variable 'externs' which holds extern symbols,
5494 pic16emitRegularMap: is modified to properly handle relocatable
5495 symbols under the new scheme,
5496 pic16createInterruptVect: is modified
5497 pic16printPublics: is modified to emit 'global' assembler directives,
5498 added pic16_printExterns to print extern symbols,
5499 pic16glue: initializes stack/frame pointer in the beginning of
5500 the assembly output. Temporary hack, will be corrected later,
5501 because gplink yet does not support stack and SDCC does not
5502 yet support a type of crt0.o object to create the final binary.
5504 * Removed many lines that contain 8051 legacy code.
5505 * The code is finally placed under a 'code' directive.
5506 * Added port specific options.
5508 * _process_pragma: simplified since now we do not need *special*
5509 include file to define SFR registers. But a separate header
5510 will be needed. This will be developed later.
5511 * _pic16_parseOptions: added, parses port specific options:
5512 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5513 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5514 --preplace-udata-with=
5516 * _pic16_setDefaultOptions: modified to initialize section names,
5517 but hack is temporarly out of order since it needs improvement.
5518 * _pic16_genAssemblerPreamble: configuration words are emitted by
5519 their address instead of their name. This part is incomplete and
5520 supports only the 18Fxx2 devices. Other devices will emit an error
5521 during assembly since they do not contain the same set of config
5523 * _pic16_genIVT: is modified,
5525 * pcode.c: added definitions for some hardware registers that are needed
5527 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5528 All PCI entries are updated. Now LFSR is supported.
5529 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5530 * added pic16_newpCodeOpLit2 to support instructions with
5531 two literal arguments
5532 * pic16_pCode2str: corrected code that emits assembler instructions
5533 with two literal operands and those that have an access bit modifier
5534 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5535 this fixes a bug which caused some labels to be lost, when an
5536 assembler directive was added, i.e. banksel,
5537 * pic16_FixRegisterBanking: improved logic that causes the insertion
5539 * InlineFunction: functions that are called once, are not any more
5540 inlined. This can be a port option in the future,
5542 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5544 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5545 hold the corresponding uninitialized symbols,
5546 * pic16_allocProcessorRegister: registers have explicit marked the
5548 * pic16_allocInternalRegister: registers are explicit marked as
5550 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5551 processing list, so bit registers were lost,
5554 * ralloc.h: added field 'accessBank' and original symbol operand
5555 in register definition,
5556 * removed the field isMapped from register definition,
5558 ** Several functions have been removed from various sources:
5559 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5560 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5561 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5562 pic16_assignRelocatableRegisters
5564 ** others have been introduced:
5565 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5566 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5568 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5570 * support/scripts/inc2h.pl: changed definition of BIT_AT
5571 to emit 'sbit at' instead of 'bit at'. This was a request.
5573 PIC16 port related preliminary changes:
5574 * gen.c: prefixed function popRegFromString with
5575 pic16_ and all references to it corrected
5576 * pcode.c: all pic16_pc_* hardware registers prefixed
5577 with underscore (_),
5578 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5579 * ralloc.c: newReg(): when register is REG_SFR then
5580 set address to rIdx,
5581 pic16_allocProcessorRegister(): marks register wasUsed=0
5582 pic16_writeUsedRegs(): added a call to assign processor
5583 registers via pic16_assignFixedRegisters
5585 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5587 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5588 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5589 variables in unused register banks. Also the SSEG is placed
5590 wherever there is enough space for it, and IDATA can be anywhere
5591 in internal RAM. For now compile using -Wl-Y[stack_size].
5592 The mem file is different for this option as well, since it
5593 makes no sense of talking about DSEG lenght.
5595 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5597 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5598 in certain cases, e.g. when ROM assignment, patch provided
5599 from Albert den Haan.
5601 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5743 SDCC_NOGENRAMCLEAR to disable this.
5744 * src/mcs51/peephole.def,
5745 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5746 (allows non-interrupt and interrupt code to safely compete for a resource

6487 support for standard C idiom of memory mapped variables; for
6488 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6489 to xdata int at 0x1234 tempvar = 1.
6490 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6491 provided by Akiya ISHIDA

6507 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6509 Fixed bug #621531 (const & volatile confusion in the type chain).
6510 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6590 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
6591 iCode properly now. Use getSize instead of nRegs since a & b
6592 aren't part of the nRegs tally.
6594 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
6596 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
6597 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
6598 before instructions that use the _STATUS register

6602 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6603 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6604 fetching of the pointer
6605 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6606 copied from genNearPointerSet()
6607 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6608 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6609 If they pop r0/r1 they must be called in the opposite order than aopOp().
6610 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6611 (resp. --stack-auto), prepared for --xstack

6620 these ports have their own __sdcc_external_start()
6622 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6624 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6625 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6626 type for bits was changed. It resulted in bit variables becoming
6627 global, which is not permitted in PIC 14 assembly output.
6629 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6631 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6644 A few small changes that speed up the peephole optimizer.
6648 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6650 Try to make the peephole optimizer smarter by maintaining
6651 an association between the assembly source code and the
6652 iCodes that originated them. Put this information to use
6653 with a new peephole rule condition "notVolatile" so that
6654 the rules can be aggressive yet still safe.
6659 * src/mcs51/peeph.def
6661 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6665 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6666 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6667 if the left or right operand symbols have the accuse flag set.
6669 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6671 Changed the type of the result of the ! (NOT) operator to char;
6672 previously it returned the same type as the source. This allows
6673 us to eliminate all the genFloatNot functions (all of its target
6674 implementations were very buggy) since !float can use the same
6677 * src/SDCCicode.c (ast2iCode): ! returns char

6684 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6686 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6687 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6688 during interrupts. Ensure WSAVE is located at a shared bank address.
6689 2. Fixed page selection in some places
6690 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6691 the registers name strings.
6692 4. Fixed "signed / unsigned compare" compiler warnings.
6693 5. The PIC port manages its own allocation of the general purpose
6694 registers, but makes no attempt to reuse them. As a result when
6695 compiling it soon runs out of general purpose registers. Some
6696 additional code was added to the files pcode.c and device.c to walk
6697 through the function call tree and rename the registers so that they
6707 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6708 genPlus() & genMinus() when the result is the same as left or right

6714 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6716 Made bitfield a distinct type from bit so that bitfields
6717 convert as per ANSI C and bits retain their traditional
6718 boolean style behaviour. Implemented bitfield support in
6726 * src/ds390/gen.c: bit v bitfield split
6727 * src/z80/gen.c: New support for bitfields
6728 * support/regression/tests/bitfields.c: reenabled z80,
6731 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6733 Rules 246.x, 247.x relate to bitfields, the others speed up
6734 access to xdata mapped I/O devices.
6736 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6738 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6740 Cleaned up genPackBits and genUnpackBits and added two helper
6741 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6742 for literal assignments in genPackBits (thanks to Frieder for
6748 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6750 Fixed bug #748310 (pointer to function type mishandled when the
6751 function name is omitted). Also fixed a SIGSEGV when a function
6752 attribute (reentrant, etc) is used on a non-function or on a
6753 function but misplaced before the parameter list.
6755 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6757 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6758 * support/Util/SDCCerr.h,
6759 * support/Util/SDCCerr.c: Added func attr misuse error msg
6761 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6763 Fixed bug #787649 by anonymous
6764 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6780 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6782 Made the constant following the "interrupt" keyword optional. If
6783 omitted, the function will not automatically be given an entry
6784 in the interrupt vector table (similar to #pragma NOIV, but
6785 less syntacticly kludgy). The interrupt number is also now
6786 range checked. Also fixed a bug in the high order bit example

7262 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7263 the regression tests I'm not brave enough to enable 245.b, 245.c
7264 * doc/sdccman.lyx: added latex preamble for hyperref package.
7265 Using pdflatex this will give you a hyperlinked pdf file with
7266 bookmarks. (prepend '%' before /usepackage if this breaks something)

7304 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7306 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7307 it can be defined with CFLAGS when running configure
7308 * src/SDCCmain.c: fixed compiling + linking with object files
7310 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7313 added --disable-pic16-port
7314 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7315 * src/SDCCmain.c: linkOptions is changed to set *,
7316 added if/endif conditional macros to remove options help
7317 messages from optionsTable when a port is not configured, added
7318 support for the PIc16 port in the ports table, when executing
7319 the compiler with no port specified on command line, a default
7320 port is selected with the new macro DEFAULT_PORT which is
7321 defined in port.h, in setDefaultOptions() linkOptions is removed
7322 from initialization assignment, since now it is a set,
7323 parseCmdLine uses setParseWithComma for linkOptions, in
7324 linkEdit() linkOptions are accessed with new function indexSet()
7325 which returns the i'th item of a set variable. See SDCCset.c, in
7326 linkEdit() when calling buildCmdLine(), added linkOptions as
7327 last argument. Now users can pass arguments to gplink via the
7328 -Wl option, main() uses pic16glue() to glue up pic16 programs

7340 * src/pic16/glue.c: commented out some error producing lines
7341 * src/pic16/main.c: __config directives are commented out to stop
7342 gpasm complaining and test the linkage with gplink, _linkCmd and
7343 _asmCmd changed to be more gplink and gpasm friendly
7344 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7345 produced an error when parsed, peep rule 12 is added to utilize
7346 movff, but it is commented out since the pCode does not support
7347 yet a command with 2 address arguments
7349 2003-05-18 <johan AT balder>
7351 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8386 * src/SDCCicode.c: fixed array add
8388 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8389 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8390 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8392 2003-01-04 <johan AT balder>
8394 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8396 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8397 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8399 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8400 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8407 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8409 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8410 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8412 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8414 * in \sdcc\as\mcs51\ changed these files in order to create an
8415 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8416 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8417 following files to include the previous two files: aslink.dsp,
8418 Makefile.aslink, Makefile.bcc, and Makefile.in.
8420 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8421 .adb instead of .cdb
8423 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8425 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8426 value from option --iram-size.
8428 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8430 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8433 2002-09-18 <wiml AT hhhh.org>
8435 * SDCClrange.h: exposed setFromRange() and setToRange()
8436 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8437 packRegsForAccUse() (bug 542397)
8438 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8439 multiple times and emitting the fetch operations more than once
8440 added aopGetUsesAcc() function to allow binary operators to
8441 fetch their operands in the correct order; made genMinus() emit
8442 compact code for X = LITERAL - Y
8444 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8445 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8446 sprintf() in line 1267.
8448 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8449 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8452 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8453 Changes to aslink (All the changes are marked with 'JCF'):
8455 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8458 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8459 area BSEG. Also moves, if possible, the DATA area down into the internal
8460 ram so more space is available.
8462 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8465 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8466 not bytes. Function summary() which creates a memory usage summary
8467 file with extension .mem. Reports of overlaping stack and small stack
8468 size. If the space for the stack is less than 16 bytes aslink trows a
8471 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8472 the 8051. Option 'y' for memory summary output file.
8474 Changes to sdcc (All the changes are marked with 'JCF'):
8476 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8478 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8479 overlaying area for it (uses RegBankUsed[4]).
8481 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8482 bank zero as used by default. By default aslink locates the stack
8483 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8484 the creation of the .mem file. Delegates the allocation of data area
8485 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8486 the begining of the stack area to aslink.
8488 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8489 glue() in SDCCglue.c creates an area for it.
8491 2002-09-03 Borut Razem <borut.razem AT siol.net>
8492 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8493 sdcc/src/pic/glue.c:
8494 introduced atexit() handler for teporay files removal in case of
8495 errors, assertions, ...
8497 2002-08-29 Borut Razem <borut.razem AT siol.net>
8498 * sdcc/support/cpp2/auto-host_vc_in.h:
8499 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8500 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8501 Maybe there is a similar problem with BORLANDC? It should be checked!
8503 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8504 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8505 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8506 was not executed, and the compiler (cl) launched a warning:
8507 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8509 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8510 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8512 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8513 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8515 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8516 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8517 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8518 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8519 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8520 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8521 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8522 - added Release configuration in VS projects
8523 - review of compiler an linker options
8524 - VC .exe files are generated in bin_vc directory, not to interfere
8525 with binaries generated from other projects (cygwin, mingw, bcc ...)
8527 * sdcc/src/yacc.dsp: added
8529 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8530 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8531 and insert the version number definitions from .version
8533 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8535 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8536 added - genarate auto-host.h using auto-host_vc_in.h as template
8539 removed from CVS, generated automatically
8541 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8542 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8544 2002-08-11 Borut Razem <borut.razem AT siol.net>
8545 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8547 2002-08-10 Borut Razem <borut.razem AT siol.net>
8548 * src/SDCCmain.c (main):
8549 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8550 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8551 The consequence was that some temporary files were not removed.
8554 unification of code in functions tempfilename() and tempfile():
8555 function tempnam() is defined in Visual Studio 6.0 and .NET
8557 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
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 - removed compiler command line option /WX: Treats all warnings as errors
8562 - update a list of source files, included into the project
8564 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8565 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8566 changed project type to Generic Project so that can be correcly converted to VS.NET project
8568 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8570 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8572 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8574 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8575 added return 0 statements after assert() to make compiler happy
8577 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8578 added newline in the def file to keep MSC compiler satisfied
8580 * sdcc/src/z80/gen.c:
8581 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8582 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8583 - solved MSC error in function aopDump()
8585 * sdcc_vc.h: define PREFIX as "\\sdcc"
8587 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8588 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8590 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8591 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8592 - Rewrote the register banking algorithm.
8593 - Added pCode live-range analysis to registers (for now, only non-used and
8594 singly-used registers optimized away)
8596 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8598 * 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.

8627 2002-03-28 Johan Knol <johan AT balder>
8629 * src/SDCCval.c: fixed bug #532436
8631 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8633 Added "char *Processor" field to the port structure.
8636 Added -p option. Allows port dependent processor to be specified.
8639 Initialized the new field char *Processor field to NULL in all ports
8642 Compiler generated registers for interrupt context saving
8643 were not getting allocated.
8645 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8648 Fixed left shift. Will promote the left side of a left shift
8649 if a) left shifting more than size of operand or b) when assigned
8650 to something size > size of left side
8652 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8654 tons of changes. Register allocation has been
8655 rewritten. Added customization for the various PICs. Flow
8656 analysis is restructured. ...
8662 Added. device.c is a PIC port hack to accomodate variations
8665 2002-03-13 Michael Hope <michaelh AT vroom>
8667 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8669 2002-03-04 johanknol <johanknol AT manik>
8671 * /src/SDCCval.c: fixed
8673 const unsigned char arr[][2] = { { 0, 1 } };
8674 t18.c:1: error: Initializer element is not constant
8676 2002-03-04 bela <bela AT manik>
8678 * /device/include/mcs51reg.h:
8679 ds89c420 register definition update
8681 2002-03-03 <johan AT FRIJA>
8683 * support/Util/SDCCerr.c: did something, but don't no why anymore
