1299 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1300 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1301 always available in leading double underscore form. The C99 support is
1302 mostly missing, but it's a start.
1303 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1304 reserved identifier "__data".
1306 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1308 * src/mcs51/peeph.def: fixed bug 1170013

1349 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1350 immedDom() returning wrong block; probably fixes bug #1160833)
1352 2005-03-20 Borut Razem <borut.razem AT siol.net>
1354 * support/scripts/inc2h.pl: WIN32 port
1356 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1358 * device/lib/makefile.in: added abs.c and labs.c
1360 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1362 * device/include/stdint.h: added
1363 * device/lib/abs.c: added
1364 * device/lib/labs.c: added
1365 * device/include/stdlib.h: added abs() and labs() prototypes
1366 * device/lib/libsdcc.lib: added abs and labs
1367 * device/include/float.h,

1372 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1374 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

1380 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1382 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1384 * device/lib/printf_large.c: removed inline assembly for portability and
1385 readability. Use printf_fast if speed or size are more important.
1386 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1387 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1389 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1391 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1392 prevent compiler warning
1394 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1396 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1397 moved to level 0 and declared as static. Also they are explicit
1398 placed in access bank. This was necessery because some times they
1399 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1400 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1401 optimizations. Currently only compare to unsigned char is implemented,
1402 * src/pic16/gen.c: added fReturnIdx array,
1403 * (struct resolvedIfx) is moved to gen.h and made public,
1404 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1405 * (aopForSym): added an optimization to directly store in stack of
1406 the operand of a SEND iCode,
1407 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1408 but as registers instead (AOP_REG) using the fReturnIdx array,
1409 * (pic16_freeAsmop): remove the freed register from the
1410 _G.sregsAlloc field,
1411 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1412 a compare of 'WREG',
1413 * (pic16_popGetTempRegCond): changed function prototype, now
1414 function takes also a bitVector argument v which holds the current
1415 set of registers that are allocated for stack access by aopForSym,
1416 registers allocated in aopForSym for accessing stack symbols are not
1417 any more part of the functions usedRegs field,
1418 * (genCall): some times aopOp is called for a stack variable to be
1419 send, aopForSym might perform the push, if this is true make sure
1420 that genCall doesn't push the variable twice by testing _G.resDirect,
1421 * (genFunction): changed testing for unspecified interrupt number
1422 from 256 to INTNO_UNSPEC,
1423 * modified selection scheme of frame pointer generation. Previously
1424 if function did use local registers a frame pointer was generated,
1425 now a frame pointer is generated only if function has arguments
1426 (that need PLUSW2 register access), or has stack arguments, or the
1427 compiler is not instructed to omit the frame pointer,
1428 * (genEndFunction): before restoring local registers that were saved
1429 in the function preamble, also restore the registers that *might*
1430 have been allocated for stack access,
1431 * (genRet): removed some old comments,
1432 * (genCmp, the active (RN's) version): added a call to the
1433 pic16_genCmp_special function to perform the compare with a more
1434 robust and optimized way,
1435 * (genInline): a feature has been added in inline code generation,
1436 which allows a wildcard variable substitution when writing inline
1437 assembly. Code is incomplete and experimental therefore undocumented,
1438 * (genCast): changed order of aopOp for result and right to allow
1439 aopForSym to directly load the result if possible,
1440 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1441 perform an optimized compare on some selected special occasions,
1442 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1443 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1444 generate an IVT any more,
1445 * src/pic16/main.c (pic16_optionsTable): added command line option
1447 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1448 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1450 * src/pic16/NOTES: Raphael Neider added in list of active developers
1451 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1452 jumptable_end to prevent bug #,
1453 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1454 inCond and outCond fields,
1455 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1456 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1457 turn off register spilling,
1458 * (packRegsForOneUse): synced with other ports' versions although it
1459 is not used currently,
1460 * (pic16_packRegisters): added an optimization while reading
1461 structure bitfields, some registers may be saved (malloc code is
1462 decreased by 80 bytes)
1464 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1466 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1467 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1468 this can be optimized more?
1470 2005-03-10 Raphael Neider <rneider AT web.de>
1472 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1473 genNearPointerGet): (hopefully) fixed access to bitfields via
1474 pointers (p->bitN = x; and x = p->bitN; failed)
1476 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1664 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1665 this might fix SIGSEGVs on MinGW...
1666 * src/SDCCopt.c (killDeadCode): restored original behaviour
1667 (volatile operands might get thrown away though)
1669 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2109 generated for switch statements. For now you need to set the
2110 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2111 Now 4 algorithms for mcs51 jumptable generation are used:
2112 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2144 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2146 * added libc directory. The current version of LibC contains string
2147 functions, ctype functions and macros and some functions of the
2148 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2149 be extensively tested in the future. Standard disclaimer here.
2150 Library is not automatically build yet. But one can build it by
2151 invoking 'make' inside the libc directory.

2161 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2162 * (pic16_storeForReturn): optimized return of 0,
2163 * (genCmp): experimental code for new genCmp which uses PIC18's
2164 special compare&skip instructions. Initial tests fail some times
2165 with variables grater than 1 byte in size, so new code is disabled,
2166 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2168 * (genCast): began a fix to optimize the casting of a bit to another
2169 bit, now assigning a bitfield to another bitfield will fail, sorry,
2170 * src/pic16/main.c: disabled the use of lr-support feature,
2171 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5192 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5194 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5195 loaded with the linker search paths (-L arguments) and the libraries
5196 to be linked with the current source (-l arguments). Changes
5197 currently will affect only the pic16 port.
5198 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5199 include path the port specific paths and port specific libraries,
5200 * gplink command now contains the $3 argument,
5201 * src/pic16/device.h,
5202 * src/pic16/device.c,: structure PIC_device is made public and
5203 renamed to PIC16_device, the same for variable Pics which is renamed

5218 Documenting changes from previous commits.
5219 * configure.in (version 1.56),
5220 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5221 when generating output files to configure the pic16 library,
5222 but now I've commented it out, since gputils aren't installed in the
5223 SF compile farm, so library won't compile
5225 * device/lib/Makefile.in (version 1.56): initially I've added in
5226 target 'all' the prerequestive 'model-pic16' so it compiled the
5227 pic16 library, but now I've commented it out for the same reasons
5229 * added targets 'model-pic16' and 'objects-pic16' to compile the
5231 * added target 'port-specific-objects-pic16' to handle the
5232 generated libraries and copy them into the build/ directory
5233 * added target 'clean-intermediate-pic16' to clean intermediate
5234 files into pic16 directory
5235 * in target 'installdirs' added line to create directory pic16 in
5236 the installation path
5238 * device/include/Makefile.in (version 1.11): in target 'install'
5239 added lines to copy all header files to installation path,
5240 * in target 'installdirs' added line create directory for pic16
5241 headers in the installation path

5257 option so that it actually works. Made it specific to the z80, since
5258 the gbz80 doesn't have these kinds of I/O ports.
5260 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5285 * src/pic16/device.c: stack is allocated via symbol and not
5286 via literal number. The symbol is placed in the corresponding
5287 position of the data ram
5288 * (pic16_dump_section): relocatable and absolute uninitialized
5289 data are now emitted in sorted order to reduce section naming,
5290 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5291 weren't marked as being in the access bank,
5293 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5295 Added portion of GNU PIC Library under the directory
5296 device/include/pic16 and device/lib/pic16. These files
5297 contain the declarations of SFRs for the PIC18Fxx2 devices.
5298 The directory is initialized via configure from toplevel.
5300 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5327 * doc/sdccman.lyx: Moved and added some sections, small changes
5328 all over. Telling LaTeX to be less strict with word spacing
5329 to better keep the right margin. Changed some notes about
5330 maintainance of the ports in section 3.2.1 - is it OK like this?
5332 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5334 SDCC source changes:
5335 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5341 processor registers declared internally by the port are emitted in
5342 the translation as equates,
5343 * src/pic16/gen.c: inline code is passed unprocessed to the

5369 UPPER for immediate operands,
5370 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5372 * src/pic16/peeph.def: all peepholes with movff are commented out,
5373 because there is a problem in the pcode peep optimizer,
5374 * src/pic16/ralloc.c: the register allocator can now reuse local
5375 function symbols for another function. This saves register usage.
5376 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5378 Added file src/pic16/NOTES with information about program writing on
5379 the current port version.

5411 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5414 * src/z80/main.c: added missed needLinkerScript flags (more than

5432 needLinkerScript flag
5434 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5435 * src/pic/glue.c: added variable udata_section_name to

5439 directive when no overlay data exist
5440 * (picglue): modified to emit uninitialized data segment
5441 according to udata_section_name

5451 2004-01-07 Borut Razem <borut.razem AT siol.net>
5453 * support/scripts/sdcc.nsi: update PATH
5454 * support/scripts/sdcc.ico: craeted

5484 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5486 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5487 (default behaviour).
5489 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5491 A python script to validate compiler diagnostic messages. It can be
5492 used to verify that sdcc complains about bad c source code and
5493 gives a good location of the error.
5494 * support/valdiag/Makefile,
5495 * support/valdiag/valdiag.py,
5496 * support/valdiag/tests/*

5513 Bug reported from Jesus Calvino-Fraga
5515 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5517 * sdcc.spec: updated
5518 * device/include/Makefile.in: don't install CVS directories
5519 * device/lib/Makefile.in: added removal of CVS directories after install
5520 * doc/Makefile: fixed install, added local_icons
5521 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5522 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5523 * src/ds390/gen.c (genRightShift): fixed bug #870788
5524 * src/SDCCast.c (decorateType): fixed bug #870781
5526 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5528 PIC16 port related changes:
5529 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5530 added variable stackPos,
5532 * gen.c: genCall, assignResultValue: added support for
5533 pushing/retrieving function parameters to/from stack,
5534 genFunction,genEndFunction: setup stack frame for the
5536 genAddrOf: will be changed according to bug 863624
5538 * added files genutils.c and genutils.h which contain gen*
5539 debugged and optimised functions extracted from gen.c
5541 * glue.c: added variable 'externs' which holds extern symbols,
5542 pic16emitRegularMap: is modified to properly handle relocatable
5543 symbols under the new scheme,
5544 pic16createInterruptVect: is modified
5545 pic16printPublics: is modified to emit 'global' assembler directives,
5546 added pic16_printExterns to print extern symbols,
5547 pic16glue: initializes stack/frame pointer in the beginning of
5548 the assembly output. Temporary hack, will be corrected later,
5549 because gplink yet does not support stack and SDCC does not
5550 yet support a type of crt0.o object to create the final binary.
5552 * Removed many lines that contain 8051 legacy code.
5553 * The code is finally placed under a 'code' directive.
5554 * Added port specific options.
5556 * _process_pragma: simplified since now we do not need *special*
5557 include file to define SFR registers. But a separate header
5558 will be needed. This will be developed later.
5559 * _pic16_parseOptions: added, parses port specific options:
5560 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5561 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5562 --preplace-udata-with=
5564 * _pic16_setDefaultOptions: modified to initialize section names,
5565 but hack is temporarly out of order since it needs improvement.
5566 * _pic16_genAssemblerPreamble: configuration words are emitted by
5567 their address instead of their name. This part is incomplete and
5568 supports only the 18Fxx2 devices. Other devices will emit an error
5569 during assembly since they do not contain the same set of config
5571 * _pic16_genIVT: is modified,
5573 * pcode.c: added definitions for some hardware registers that are needed
5575 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5576 All PCI entries are updated. Now LFSR is supported.
5577 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5578 * added pic16_newpCodeOpLit2 to support instructions with
5579 two literal arguments
5580 * pic16_pCode2str: corrected code that emits assembler instructions
5581 with two literal operands and those that have an access bit modifier
5582 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5583 this fixes a bug which caused some labels to be lost, when an
5584 assembler directive was added, i.e. banksel,
5585 * pic16_FixRegisterBanking: improved logic that causes the insertion
5587 * InlineFunction: functions that are called once, are not any more
5588 inlined. This can be a port option in the future,
5590 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5592 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5593 hold the corresponding uninitialized symbols,
5594 * pic16_allocProcessorRegister: registers have explicit marked the
5596 * pic16_allocInternalRegister: registers are explicit marked as
5598 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5599 processing list, so bit registers were lost,
5602 * ralloc.h: added field 'accessBank' and original symbol operand
5603 in register definition,
5604 * removed the field isMapped from register definition,
5606 ** Several functions have been removed from various sources:
5607 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5608 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5609 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5610 pic16_assignRelocatableRegisters
5612 ** others have been introduced:
5613 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5614 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5616 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5618 * support/scripts/inc2h.pl: changed definition of BIT_AT
5619 to emit 'sbit at' instead of 'bit at'. This was a request.
5621 PIC16 port related preliminary changes:
5622 * gen.c: prefixed function popRegFromString with
5623 pic16_ and all references to it corrected
5624 * pcode.c: all pic16_pc_* hardware registers prefixed
5625 with underscore (_),
5626 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5627 * ralloc.c: newReg(): when register is REG_SFR then
5628 set address to rIdx,
5629 pic16_allocProcessorRegister(): marks register wasUsed=0
5630 pic16_writeUsedRegs(): added a call to assign processor
5631 registers via pic16_assignFixedRegisters
5633 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5635 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5636 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5637 variables in unused register banks. Also the SSEG is placed
5638 wherever there is enough space for it, and IDATA can be anywhere
5639 in internal RAM. For now compile using -Wl-Y[stack_size].
5640 The mem file is different for this option as well, since it
5641 makes no sense of talking about DSEG lenght.
5643 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5645 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5646 in certain cases, e.g. when ROM assignment, patch provided
5647 from Albert den Haan.
5649 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5789 * src/mcs51/main.c: fixed bug #737001 for the mcs51. SDCC clears
5790 xdata and data memory on startup. Set the environment variable
5791 SDCC_NOGENRAMCLEAR to disable this.
5792 * src/mcs51/peephole.def,
5793 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5794 (allows non-interrupt and interrupt code to safely compete for a resource
5795 without the non-interrupt code having to disable interrupts)
5797 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5799 * src/SDCCicode.c (geniCodeAdd),
5800 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
5801 with valFromType if type might be a pointer and host is big endian).
5802 * src/SDCCast.c (decorateType): unary plus compatible with all arithmetic
5803 types, not just integer types.

5814 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5816 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
5817 Apparently this did not see much testing (endless loop)
5819 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5821 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
5823 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5892 it breaks with bitfields, extern declarations, and gcse analysis.
5893 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5894 could be assigned through a pointer, so don't complain.

6670 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6672 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6673 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6674 type for bits was changed. It resulted in bit variables becoming
6675 global, which is not permitted in PIC 14 assembly output.
6677 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6679 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6692 A few small changes that speed up the peephole optimizer.
6696 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6698 Try to make the peephole optimizer smarter by maintaining
6699 an association between the assembly source code and the
6700 iCodes that originated them. Put this information to use
6701 with a new peephole rule condition "notVolatile" so that
6702 the rules can be aggressive yet still safe.
6707 * src/mcs51/peeph.def
6709 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6713 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6714 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6715 if the left or right operand symbols have the accuse flag set.
6717 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6719 Changed the type of the result of the ! (NOT) operator to char;
6720 previously it returned the same type as the source. This allows
6721 us to eliminate all the genFloatNot functions (all of its target
6722 implementations were very buggy) since !float can use the same
6725 * src/SDCCicode.c (ast2iCode): ! returns char

6734 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6735 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6736 during interrupts. Ensure WSAVE is located at a shared bank address.
6737 2. Fixed page selection in some places
6738 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6739 the registers name strings.
6740 4. Fixed "signed / unsigned compare" compiler warnings.
6741 5. The PIC port manages its own allocation of the general purpose
6742 registers, but makes no attempt to reuse them. As a result when
6743 compiling it soon runs out of general purpose registers. Some
6744 additional code was added to the files pcode.c and device.c to walk
6745 through the function call tree and rename the registers so that they
6755 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6756 genPlus() & genMinus() when the result is the same as left or right

6762 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6764 Made bitfield a distinct type from bit so that bitfields
6765 convert as per ANSI C and bits retain their traditional
6766 boolean style behaviour. Implemented bitfield support in
6774 * src/ds390/gen.c: bit v bitfield split
6775 * src/z80/gen.c: New support for bitfields
6776 * support/regression/tests/bitfields.c: reenabled z80,
6779 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6781 Rules 246.x, 247.x relate to bitfields, the others speed up
6782 access to xdata mapped I/O devices.
6784 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x

6788 Cleaned up genPackBits and genUnpackBits and added two helper
6789 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6790 for literal assignments in genPackBits (thanks to Frieder for
6796 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6798 Fixed bug #748310 (pointer to function type mishandled when the
6799 function name is omitted). Also fixed a SIGSEGV when a function
6800 attribute (reentrant, etc) is used on a non-function or on a
6801 function but misplaced before the parameter list.
6803 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6805 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6828 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6830 Made the constant following the "interrupt" keyword optional. If
6831 omitted, the function will not automatically be given an entry
6832 in the interrupt vector table (similar to #pragma NOIV, but
6833 less syntacticly kludgy). The interrupt number is also now
6834 range checked. Also fixed a bug in the high order bit example
6841 * support/Util/SDCCerr.c

6855 unsigned, but are signed by default
6856 * src/SDCCval.c (constVal): rearranged
6857 * src/SDCCval.c (valMod): preliminary fix
6858 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7362 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7363 * src/SDCCmain.c: linkOptions is changed to set *,
7364 added if/endif conditional macros to remove options help
7365 messages from optionsTable when a port is not configured, added
7366 support for the PIc16 port in the ports table, when executing
7367 the compiler with no port specified on command line, a default
7368 port is selected with the new macro DEFAULT_PORT which is
7369 defined in port.h, in setDefaultOptions() linkOptions is removed
7370 from initialization assignment, since now it is a set,
7371 parseCmdLine uses setParseWithComma for linkOptions, in
7372 linkEdit() linkOptions are accessed with new function indexSet()
7373 which returns the i'th item of a set variable. See SDCCset.c, in
7374 linkEdit() when calling buildCmdLine(), added linkOptions as
7375 last argument. Now users can pass arguments to gplink via the
7376 -Wl option, main() uses pic16glue() to glue up pic16 programs

7388 * src/pic16/glue.c: commented out some error producing lines
7389 * src/pic16/main.c: __config directives are commented out to stop
7390 gpasm complaining and test the linkage with gplink, _linkCmd and
7391 _asmCmd changed to be more gplink and gpasm friendly
7392 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7393 produced an error when parsed, peep rule 12 is added to utilize
7394 movff, but it is commented out since the pCode does not support
7395 yet a command with 2 address arguments

8434 * src/SDCCicode.c: fixed array add
8436 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8437 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8438 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8440 2003-01-04 <johan AT balder>
8442 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8444 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8445 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8447 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8457 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8458 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8460 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8462 * in \sdcc\as\mcs51\ changed these files in order to create an
8463 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8464 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8465 following files to include the previous two files: aslink.dsp,
8466 Makefile.aslink, Makefile.bcc, and Makefile.in.
8468 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8469 .adb instead of .cdb
8471 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8473 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8474 value from option --iram-size.
8476 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8478 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8481 2002-09-18 <wiml AT hhhh.org>
8483 * SDCClrange.h: exposed setFromRange() and setToRange()
8484 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8485 packRegsForAccUse() (bug 542397)
8486 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8487 multiple times and emitting the fetch operations more than once
8488 added aopGetUsesAcc() function to allow binary operators to
8489 fetch their operands in the correct order; made genMinus() emit
8490 compact code for X = LITERAL - Y
8492 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8493 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8494 sprintf() in line 1267.
8496 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8497 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8500 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8501 Changes to aslink (All the changes are marked with 'JCF'):
8503 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8506 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8507 area BSEG. Also moves, if possible, the DATA area down into the internal
8508 ram so more space is available.
8510 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8513 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8514 not bytes. Function summary() which creates a memory usage summary
8515 file with extension .mem. Reports of overlaping stack and small stack
8516 size. If the space for the stack is less than 16 bytes aslink trows a
8519 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8520 the 8051. Option 'y' for memory summary output file.
8522 Changes to sdcc (All the changes are marked with 'JCF'):
8524 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8526 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8527 overlaying area for it (uses RegBankUsed[4]).
8529 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8530 bank zero as used by default. By default aslink locates the stack
8531 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8532 the creation of the .mem file. Delegates the allocation of data area
8533 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8534 the begining of the stack area to aslink.
8536 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8537 glue() in SDCCglue.c creates an area for it.
8539 2002-09-03 Borut Razem <borut.razem AT siol.net>
8540 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8541 sdcc/src/pic/glue.c:
8542 introduced atexit() handler for teporay files removal in case of
8543 errors, assertions, ...
8545 2002-08-29 Borut Razem <borut.razem AT siol.net>
8546 * sdcc/support/cpp2/auto-host_vc_in.h:
8547 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8548 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8549 Maybe there is a similar problem with BORLANDC? It should be checked!
8551 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8552 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8553 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8554 was not executed, and the compiler (cl) launched a warning:
8555 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8557 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8558 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8560 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8561 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8563 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8564 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8565 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8566 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8567 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8568 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8569 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8570 - added Release configuration in VS projects
8571 - review of compiler an linker options
8572 - VC .exe files are generated in bin_vc directory, not to interfere
8573 with binaries generated from other projects (cygwin, mingw, bcc ...)
8575 * sdcc/src/yacc.dsp: added
8577 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8578 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8579 and insert the version number definitions from .version
8581 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8583 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8584 added - genarate auto-host.h using auto-host_vc_in.h as template
8587 removed from CVS, generated automatically
8589 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8590 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8592 2002-08-11 Borut Razem <borut.razem AT siol.net>
8593 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8595 2002-08-10 Borut Razem <borut.razem AT siol.net>
8596 * src/SDCCmain.c (main):
8597 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8598 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8599 The consequence was that some temporary files were not removed.
8602 unification of code in functions tempfilename() and tempfile():
8603 function tempnam() is defined in Visual Studio 6.0 and .NET
8605 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8607 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8608 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8609 - removed compiler command line option /WX: Treats all warnings as errors
8610 - update a list of source files, included into the project
8612 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8613 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8614 changed project type to Generic Project so that can be correcly converted to VS.NET project
8616 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8618 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8620 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8622 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8623 added return 0 statements after assert() to make compiler happy
8625 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8626 added newline in the def file to keep MSC compiler satisfied
8628 * sdcc/src/z80/gen.c:
8629 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8630 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8631 - solved MSC error in function aopDump()
8633 * sdcc_vc.h: define PREFIX as "\\sdcc"
8635 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8636 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8638 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8639 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8640 - Rewrote the register banking algorithm.
8641 - Added pCode live-range analysis to registers (for now, only non-used and
8642 singly-used registers optimized away)
8644 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8646 * 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.
8648 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8649 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8651 2002-04-22 Michael Hope <michaelh AT vroom>
8653 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
