1470 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1471 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1472 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1473 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1474 always available in leading double underscore form. The C99 support is
1475 mostly missing, but it's a start.
1476 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1477 reserved identifier "__data".

1555 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1557 * device/lib/printf_large.c: removed inline assembly for portability and
1558 readability. Use printf_fast if speed or size are more important.
1559 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1560 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1562 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1564 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1565 prevent compiler warning
1567 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1569 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1570 moved to level 0 and declared as static. Also they are explicit
1571 placed in access bank. This was necessery because some times they
1572 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1573 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1574 optimizations. Currently only compare to unsigned char is implemented,
1575 * src/pic16/gen.c: added fReturnIdx array,
1576 * (struct resolvedIfx) is moved to gen.h and made public,
1577 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1578 * (aopForSym): added an optimization to directly store in stack of
1579 the operand of a SEND iCode,
1580 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1581 but as registers instead (AOP_REG) using the fReturnIdx array,
1582 * (pic16_freeAsmop): remove the freed register from the
1583 _G.sregsAlloc field,
1584 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1585 a compare of 'WREG',
1586 * (pic16_popGetTempRegCond): changed function prototype, now
1587 function takes also a bitVector argument v which holds the current
1588 set of registers that are allocated for stack access by aopForSym,
1589 registers allocated in aopForSym for accessing stack symbols are not
1590 any more part of the functions usedRegs field,
1591 * (genCall): some times aopOp is called for a stack variable to be
1592 send, aopForSym might perform the push, if this is true make sure
1593 that genCall doesn't push the variable twice by testing _G.resDirect,
1594 * (genFunction): changed testing for unspecified interrupt number
1595 from 256 to INTNO_UNSPEC,
1596 * modified selection scheme of frame pointer generation. Previously
1597 if function did use local registers a frame pointer was generated,
1598 now a frame pointer is generated only if function has arguments
1599 (that need PLUSW2 register access), or has stack arguments, or the
1600 compiler is not instructed to omit the frame pointer,
1601 * (genEndFunction): before restoring local registers that were saved
1602 in the function preamble, also restore the registers that *might*
1603 have been allocated for stack access,
1604 * (genRet): removed some old comments,
1605 * (genCmp, the active (RN's) version): added a call to the
1606 pic16_genCmp_special function to perform the compare with a more
1607 robust and optimized way,
1608 * (genInline): a feature has been added in inline code generation,
1609 which allows a wildcard variable substitution when writing inline
1610 assembly. Code is incomplete and experimental therefore undocumented,
1611 * (genCast): changed order of aopOp for result and right to allow
1612 aopForSym to directly load the result if possible,
1613 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1614 perform an optimized compare on some selected special occasions,
1615 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1616 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1617 generate an IVT any more,
1618 * src/pic16/main.c (pic16_optionsTable): added command line option
1620 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1621 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1623 * src/pic16/NOTES: Raphael Neider added in list of active developers
1624 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1625 jumptable_end to prevent bug #,
1626 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1627 inCond and outCond fields,
1628 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1629 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1630 turn off register spilling,
1631 * (packRegsForOneUse): synced with other ports' versions although it
1632 is not used currently,
1633 * (pic16_packRegisters): added an optimization while reading
1634 structure bitfields, some registers may be saved (malloc code is
1635 decreased by 80 bytes)
1637 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1639 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1640 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1641 this can be optimized more?
1643 2005-03-10 Raphael Neider <rneider AT web.de>
1645 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1646 genNearPointerGet): (hopefully) fixed access to bitfields via
1647 pointers (p->bitN = x; and x = p->bitN; failed)

1692 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1693 to keep the correct label reference count when adding/removing references
1694 to labels. A peephole file using this is appended to patch #1144962.
1696 2005-02-14 Raphael Neider <rneider AT web.de>

2281 Adding support for replacing ljmps with sjmps in jumptables
2282 generated for switch statements. For now you need to set the
2283 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2284 Now 4 algorithms for mcs51 jumptable generation are used:
2285 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2286 addresses loaded pc-relative for up to 112 cases and stack-pushing
2287 target addresses loaded with offset from dptr for up to 256 cases.

2317 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2319 * added libc directory. The current version of LibC contains string
2320 functions, ctype functions and macros and some functions of the
2321 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2322 be extensively tested in the future. Standard disclaimer here.
2323 Library is not automatically build yet. But one can build it by
2324 invoking 'make' inside the libc directory.
2325 * added ADC library under libio. Preliminary version yet.

2335 * (pic16_storeForReturn): optimized return of 0,
2336 * (genCmp): experimental code for new genCmp which uses PIC18's
2337 special compare&skip instructions. Initial tests fail some times
2338 with variables grater than 1 byte in size, so new code is disabled,
2339 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2341 * (genCast): began a fix to optimize the casting of a bit to another
2342 bit, now assigning a bitfield to another bitfield will fail, sorry,
2343 * src/pic16/main.c: disabled the use of lr-support feature,
2344 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2347 bits with offset (case PO_GPR_BIT),
2348 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2350 * (isBankInstruction): modified to return 0 for no banking instruction,
2351 and 1 for banking instruction,
2352 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2353 caused stop processing pCodes after a inline assembly block,
2354 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2356 registers when it shouldn't,
2357 * src/pic16/ralloc.c (allocReg): add preliminary support for
2358 supporting a limited set of temporary registers,
2360 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2362 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2366 (genFunction): optimize RECEIVE iCodes in reentrant functions
2368 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2370 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5248 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5250 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
5251 virus/worm forged address usage.
5253 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5255 Fixed promotion, it should be done on AST level:
5256 * src/SDCCast.c (addCast): added promotion to int
5257 (decorateType): updated call to upCast()
5258 * src/SDCCicode.c (geniCodeLeftShift): removed call to
5259 usualUnaryConversions()
5261 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
5263 * support/regression/tests/literalop.c (mulWrapper): Added a
5264 wrapper to remove integer overflow warnings.
5266 * support/regression/tests/float_trans.c: Made work on host.
5268 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
5271 * support/regression/generate-cases.py (main): Changed from inline
5274 * doc/Makefile (install): Changed to depth first to get rid of
5275 missing directory install warning.
5277 * as/Makefile (install-doc): Made work on Mac.
5279 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5281 * src/SDCCast.c: added an additional type flow in decorateType() of
5282 opposite direction, see feature request #860006; it's enabled at runtime
5283 by setting the environment variable SDCC_NEWTYPEFLOW
5284 * src/SDCCast.h: changed prototype of decorateType()
5285 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5286 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5287 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5288 see feature request #877103
5289 * src/SDCCval.c: updated call of decorateType()
5290 (valBitwise): fixed bug #882876
5291 (valMinus): added promotion
5292 (valLogicAndOr): result is unsigned
5293 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5294 * src/SDCCsymt.c (computeType),
5295 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5296 must not cause an unsigned operation

5317 * src/pic/ralloc.h: applied patch from Slade Rich;
5318 added support for multiple code pages and multiple RAM banks on the
5319 PIC 14 port. The ASM files now no longer simply assume all the
5320 code / RAM are in the same page / bank. This means the linker can
5321 safely allocate code/RAM of separate ASM files to different pages/banks.
5322 * doc/sdccman.lyx: added Slade's tips
5323 * src/mcs51/peeph.def: fixed bug #880768

5335 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5336 strtof is not part of C89 and isn't included with Mac OS X.
5338 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5340 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5365 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5367 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5368 loaded with the linker search paths (-L arguments) and the libraries
5369 to be linked with the current source (-l arguments). Changes
5370 currently will affect only the pic16 port.
5371 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5372 include path the port specific paths and port specific libraries,
5373 * gplink command now contains the $3 argument,
5374 * src/pic16/device.h,
5375 * src/pic16/device.c,: structure PIC_device is made public and
5376 renamed to PIC16_device, the same for variable Pics which is renamed

5391 Documenting changes from previous commits.
5392 * configure.in (version 1.56),
5393 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5394 when generating output files to configure the pic16 library,
5395 but now I've commented it out, since gputils aren't installed in the
5396 SF compile farm, so library won't compile
5398 * device/lib/Makefile.in (version 1.56): initially I've added in
5399 target 'all' the prerequestive 'model-pic16' so it compiled the
5400 pic16 library, but now I've commented it out for the same reasons
5402 * added targets 'model-pic16' and 'objects-pic16' to compile the
5404 * added target 'port-specific-objects-pic16' to handle the
5405 generated libraries and copy them into the build/ directory
5406 * added target 'clean-intermediate-pic16' to clean intermediate
5407 files into pic16 directory
5408 * in target 'installdirs' added line to create directory pic16 in
5409 the installation path
5411 * device/include/Makefile.in (version 1.11): in target 'install'
5412 added lines to copy all header files to installation path,
5413 * in target 'installdirs' added line create directory for pic16
5414 headers in the installation path

5429 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5430 option so that it actually works. Made it specific to the z80, since
5431 the gbz80 doesn't have these kinds of I/O ports.
5433 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5435 * device/include/z180.h,

5457 Mainly changes to support compilation of the device libraries
5458 * src/pic16/device.c: stack is allocated via symbol and not
5459 via literal number. The symbol is placed in the corresponding
5460 position of the data ram
5461 * (pic16_dump_section): relocatable and absolute uninitialized
5462 data are now emitted in sorted order to reduce section naming,
5463 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5464 weren't marked as being in the access bank,
5466 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5468 Added portion of GNU PIC Library under the directory
5469 device/include/pic16 and device/lib/pic16. These files
5470 contain the declarations of SFRs for the PIC18Fxx2 devices.
5471 The directory is initialized via configure from toplevel.
5473 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5475 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5487 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5489 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5490 in simpler and even better code

5501 all over. Telling LaTeX to be less strict with word spacing
5502 to better keep the right margin. Changed some notes about
5503 maintainance of the ports in section 3.2.1 - is it OK like this?
5505 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5543 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5545 * src/pic16/peeph.def: all peepholes with movff are commented out,
5546 because there is a problem in the pcode peep optimizer,
5547 * src/pic16/ralloc.c: the register allocator can now reuse local

5549 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5551 Added file src/pic16/NOTES with information about program writing on
5552 the current port version.

5686 Bug reported from Jesus Calvino-Fraga
5688 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5690 * sdcc.spec: updated
5691 * device/include/Makefile.in: don't install CVS directories
5692 * device/lib/Makefile.in: added removal of CVS directories after install
5693 * doc/Makefile: fixed install, added local_icons
5694 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5695 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5696 * src/ds390/gen.c (genRightShift): fixed bug #870788
5697 * src/SDCCast.c (decorateType): fixed bug #870781
5699 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5701 PIC16 port related changes:
5702 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5703 added variable stackPos,
5705 * gen.c: genCall, assignResultValue: added support for
5706 pushing/retrieving function parameters to/from stack,
5707 genFunction,genEndFunction: setup stack frame for the
5709 genAddrOf: will be changed according to bug 863624
5711 * added files genutils.c and genutils.h which contain gen*
5712 debugged and optimised functions extracted from gen.c
5714 * glue.c: added variable 'externs' which holds extern symbols,
5715 pic16emitRegularMap: is modified to properly handle relocatable
5716 symbols under the new scheme,
5717 pic16createInterruptVect: is modified
5718 pic16printPublics: is modified to emit 'global' assembler directives,
5719 added pic16_printExterns to print extern symbols,
5720 pic16glue: initializes stack/frame pointer in the beginning of
5721 the assembly output. Temporary hack, will be corrected later,
5722 because gplink yet does not support stack and SDCC does not
5723 yet support a type of crt0.o object to create the final binary.
5725 * Removed many lines that contain 8051 legacy code.
5726 * The code is finally placed under a 'code' directive.
5727 * Added port specific options.
5729 * _process_pragma: simplified since now we do not need *special*
5730 include file to define SFR registers. But a separate header
5731 will be needed. This will be developed later.
5732 * _pic16_parseOptions: added, parses port specific options:
5733 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5734 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5735 --preplace-udata-with=
5737 * _pic16_setDefaultOptions: modified to initialize section names,
5738 but hack is temporarly out of order since it needs improvement.
5739 * _pic16_genAssemblerPreamble: configuration words are emitted by
5740 their address instead of their name. This part is incomplete and
5741 supports only the 18Fxx2 devices. Other devices will emit an error
5742 during assembly since they do not contain the same set of config
5744 * _pic16_genIVT: is modified,
5746 * pcode.c: added definitions for some hardware registers that are needed
5748 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5749 All PCI entries are updated. Now LFSR is supported.
5750 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5751 * added pic16_newpCodeOpLit2 to support instructions with
5752 two literal arguments
5753 * pic16_pCode2str: corrected code that emits assembler instructions
5754 with two literal operands and those that have an access bit modifier
5755 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5756 this fixes a bug which caused some labels to be lost, when an
5757 assembler directive was added, i.e. banksel,
5758 * pic16_FixRegisterBanking: improved logic that causes the insertion
5760 * InlineFunction: functions that are called once, are not any more
5761 inlined. This can be a port option in the future,
5763 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5765 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5766 hold the corresponding uninitialized symbols,
5767 * pic16_allocProcessorRegister: registers have explicit marked the
5769 * pic16_allocInternalRegister: registers are explicit marked as
5771 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5772 processing list, so bit registers were lost,
5775 * ralloc.h: added field 'accessBank' and original symbol operand
5776 in register definition,
5777 * removed the field isMapped from register definition,
5779 ** Several functions have been removed from various sources:
5780 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5781 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5782 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5783 pic16_assignRelocatableRegisters
5785 ** others have been introduced:
5786 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5787 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5789 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5791 * support/scripts/inc2h.pl: changed definition of BIT_AT
5792 to emit 'sbit at' instead of 'bit at'. This was a request.
5794 PIC16 port related preliminary changes:
5795 * gen.c: prefixed function popRegFromString with
5796 pic16_ and all references to it corrected
5797 * pcode.c: all pic16_pc_* hardware registers prefixed
5798 with underscore (_),
5799 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5800 * ralloc.c: newReg(): when register is REG_SFR then
5801 set address to rIdx,
5802 pic16_allocProcessorRegister(): marks register wasUsed=0
5803 pic16_writeUsedRegs(): added a call to assign processor
5804 registers via pic16_assignFixedRegisters
5806 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5808 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5809 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5810 variables in unused register banks. Also the SSEG is placed
5811 wherever there is enough space for it, and IDATA can be anywhere
5812 in internal RAM. For now compile using -Wl-Y[stack_size].
5813 The mem file is different for this option as well, since it
5814 makes no sense of talking about DSEG lenght.
5816 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5818 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5819 in certain cases, e.g. when ROM assignment, patch provided
5820 from Albert den Haan.

6063 * src/SDCCast.c (decorateType): disabled a transformation I added in
6064 revision 1.188 (access to fields of a structure at an absolute address);
6065 it breaks with bitfields, extern declarations, and gcse analysis.
6066 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6067 could be assigned through a pointer, so don't complain.

6175 xdata initialization slightly shorter
6177 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6824 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6825 fetching of the pointer
6826 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6827 copied from genNearPointerSet()
6828 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6829 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6845 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6846 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6847 type for bits was changed. It resulted in bit variables becoming
6848 global, which is not permitted in PIC 14 assembly output.
6850 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6852 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6865 A few small changes that speed up the peephole optimizer.
6869 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6871 Try to make the peephole optimizer smarter by maintaining
6872 an association between the assembly source code and the
6873 iCodes that originated them. Put this information to use
6874 with a new peephole rule condition "notVolatile" so that
6875 the rules can be aggressive yet still safe.
6880 * src/mcs51/peeph.def
6882 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6886 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6887 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6888 if the left or right operand symbols have the accuse flag set.
6890 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6892 Changed the type of the result of the ! (NOT) operator to char;
6893 previously it returned the same type as the source. This allows
6894 us to eliminate all the genFloatNot functions (all of its target
6895 implementations were very buggy) since !float can use the same
6898 * src/SDCCicode.c (ast2iCode): ! returns char

6907 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6908 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6909 during interrupts. Ensure WSAVE is located at a shared bank address.
6910 2. Fixed page selection in some places
6911 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6912 the registers name strings.
6913 4. Fixed "signed / unsigned compare" compiler warnings.
6914 5. The PIC port manages its own allocation of the general purpose
6915 registers, but makes no attempt to reuse them. As a result when
6916 compiling it soon runs out of general purpose registers. Some
6917 additional code was added to the files pcode.c and device.c to walk
6918 through the function call tree and rename the registers so that they
6928 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6929 genPlus() & genMinus() when the result is the same as left or right

6935 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6937 Made bitfield a distinct type from bit so that bitfields
6938 convert as per ANSI C and bits retain their traditional
6939 boolean style behaviour. Implemented bitfield support in
6947 * src/ds390/gen.c: bit v bitfield split
6948 * src/z80/gen.c: New support for bitfields
6949 * support/regression/tests/bitfields.c: reenabled z80,
6952 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6954 Rules 246.x, 247.x relate to bitfields, the others speed up
6955 access to xdata mapped I/O devices.
6957 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6959 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6961 Cleaned up genPackBits and genUnpackBits and added two helper
6962 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6963 for literal assignments in genPackBits (thanks to Frieder for
6969 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6971 Fixed bug #748310 (pointer to function type mishandled when the
6972 function name is omitted). Also fixed a SIGSEGV when a function
6973 attribute (reentrant, etc) is used on a non-function or on a
6974 function but misplaced before the parameter list.
6976 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6978 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6979 * support/Util/SDCCerr.h,

7001 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7003 Made the constant following the "interrupt" keyword optional. If
7004 omitted, the function will not automatically be given an entry
7005 in the interrupt vector table (similar to #pragma NOIV, but
7006 less syntacticly kludgy). The interrupt number is also now
7007 range checked. Also fixed a bug in the high order bit example

7021 * src/SDCCicode.c (operandOperation): rewritten some ops
7022 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7023 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7025 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7026 be re-activated by defining REDUCE_LITERALS)
7027 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7028 unsigned, but are signed by default
7029 * src/SDCCval.c (constVal): rearranged
7030 * src/SDCCval.c (valMod): preliminary fix
7031 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7073 constants are unsigned; added recognition of "u" flag for unsigned
7074 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7075 * src/SDCCval.c (valDiv, valMod): fixed signdness
7076 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7077 signedness of modulo, left and right shift

7486 Using pdflatex this will give you a hyperlinked pdf file with
7487 bookmarks. (prepend '%' before /usepackage if this breaks something)

7525 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7527 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7528 it can be defined with CFLAGS when running configure
7529 * src/SDCCmain.c: fixed compiling + linking with object files
7531 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7534 added --disable-pic16-port
7535 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7536 * src/SDCCmain.c: linkOptions is changed to set *,
7537 added if/endif conditional macros to remove options help
7538 messages from optionsTable when a port is not configured, added
7539 support for the PIc16 port in the ports table, when executing
7540 the compiler with no port specified on command line, a default
7541 port is selected with the new macro DEFAULT_PORT which is
7542 defined in port.h, in setDefaultOptions() linkOptions is removed
7543 from initialization assignment, since now it is a set,
7544 parseCmdLine uses setParseWithComma for linkOptions, in
7545 linkEdit() linkOptions are accessed with new function indexSet()
7546 which returns the i'th item of a set variable. See SDCCset.c, in
7547 linkEdit() when calling buildCmdLine(), added linkOptions as
7548 last argument. Now users can pass arguments to gplink via the
7549 -Wl option, main() uses pic16glue() to glue up pic16 programs
7550 * src/SDCCpeeph.c: various changes to support pic16

7561 * src/pic16/glue.c: commented out some error producing lines
7562 * src/pic16/main.c: __config directives are commented out to stop
7563 gpasm complaining and test the linkage with gplink, _linkCmd and
7564 _asmCmd changed to be more gplink and gpasm friendly
7565 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7566 produced an error when parsed, peep rule 12 is added to utilize
7567 movff, but it is commented out since the pCode does not support
7568 yet a command with 2 address arguments
7570 2003-05-18 <johan AT balder>
7572 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7573 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7599 2003-05-11 Borut Razem <borut.razem AT siol.net>
7601 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7602 the path of bin directory, so that PATH is the only env. variable, which has to be set
7603 in case of standard installation.
7604 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8661 added aopGetUsesAcc() function to allow binary operators to
8662 fetch their operands in the correct order; made genMinus() emit
8663 compact code for X = LITERAL - Y
8665 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8666 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8667 sprintf() in line 1267.
8669 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8670 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8673 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8674 Changes to aslink (All the changes are marked with 'JCF'):
8676 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8679 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8680 area BSEG. Also moves, if possible, the DATA area down into the internal
8681 ram so more space is available.
8683 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8686 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8687 not bytes. Function summary() which creates a memory usage summary
8688 file with extension .mem. Reports of overlaping stack and small stack
8689 size. If the space for the stack is less than 16 bytes aslink trows a
8692 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8693 the 8051. Option 'y' for memory summary output file.
8695 Changes to sdcc (All the changes are marked with 'JCF'):
8697 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8699 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8700 overlaying area for it (uses RegBankUsed[4]).
8702 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8703 bank zero as used by default. By default aslink locates the stack
8704 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8705 the creation of the .mem file. Delegates the allocation of data area
8706 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8707 the begining of the stack area to aslink.
8709 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8710 glue() in SDCCglue.c creates an area for it.
8712 2002-09-03 Borut Razem <borut.razem AT siol.net>
8713 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8714 sdcc/src/pic/glue.c:
8715 introduced atexit() handler for teporay files removal in case of
8716 errors, assertions, ...
8718 2002-08-29 Borut Razem <borut.razem AT siol.net>
8719 * sdcc/support/cpp2/auto-host_vc_in.h:
8720 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8721 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8722 Maybe there is a similar problem with BORLANDC? It should be checked!
8724 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8725 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8726 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8727 was not executed, and the compiler (cl) launched a warning:
8728 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8730 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8731 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8733 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8734 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8736 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8737 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8738 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8739 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8740 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8741 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8742 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8743 - added Release configuration in VS projects
8744 - review of compiler an linker options
8745 - VC .exe files are generated in bin_vc directory, not to interfere
8746 with binaries generated from other projects (cygwin, mingw, bcc ...)
8748 * sdcc/src/yacc.dsp: added
8750 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8751 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8752 and insert the version number definitions from .version
8754 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8756 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8757 added - genarate auto-host.h using auto-host_vc_in.h as template
8760 removed from CVS, generated automatically
8762 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8763 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8765 2002-08-11 Borut Razem <borut.razem AT siol.net>
8766 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8768 2002-08-10 Borut Razem <borut.razem AT siol.net>
8769 * src/SDCCmain.c (main):
8770 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8771 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8772 The consequence was that some temporary files were not removed.
8775 unification of code in functions tempfilename() and tempfile():
8776 function tempnam() is defined in Visual Studio 6.0 and .NET
8778 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8780 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8781 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8782 - removed compiler command line option /WX: Treats all warnings as errors
8783 - update a list of source files, included into the project
8785 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8786 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8787 changed project type to Generic Project so that can be correcly converted to VS.NET project
8789 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8791 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8793 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8795 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8796 added return 0 statements after assert() to make compiler happy
8798 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8799 added newline in the def file to keep MSC compiler satisfied
8801 * sdcc/src/z80/gen.c:
8802 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8803 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8804 - solved MSC error in function aopDump()
8806 * sdcc_vc.h: define PREFIX as "\\sdcc"
8808 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8809 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8812 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8813 - Rewrote the register banking algorithm.
8814 - Added pCode live-range analysis to registers (for now, only non-used and
8815 singly-used registers optimized away)
8817 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

8848 2002-03-28 Johan Knol <johan AT balder>
8850 * src/SDCCval.c: fixed bug #532436
8852 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8854 Added "char *Processor" field to the port structure.
8857 Added -p option. Allows port dependent processor to be specified.
8860 Initialized the new field char *Processor field to NULL in all ports
8863 Compiler generated registers for interrupt context saving
8864 were not getting allocated.
8866 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8869 Fixed left shift. Will promote the left side of a left shift
8870 if a) left shifting more than size of operand or b) when assigned
8871 to something size > size of left side
8873 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8875 tons of changes. Register allocation has been
8876 rewritten. Added customization for the various PICs. Flow
8877 analysis is restructured. ...
8883 Added. device.c is a PIC port hack to accomodate variations
8886 2002-03-13 Michael Hope <michaelh AT vroom>
8888 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8981 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8983 * sdcc/src/SDCCloop.c:
8984 Previous fix was not good. basic blocks that have "break" or "return" are
8985 not really partof a loop , but live ranges used in these blocks should
8986 be live thru the entire loop, so set partOfLoop but don't add them to
8989 2002-02-21 <johan AT FRIJA>
8991 * src/SDCCcse.c: fixed bug #514308
8993 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8996 Fixed BUG #519583. If a conditional block ended in a return/break
8997 statement inside a loop, it was not being considered part of the loop.
8999 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9001 2002-02-10 Karl Bongers <karl AT turbobit.com>
9004 Fixed up SDCDB debugger somewhat. Updated debugger/README
9005 with lots of comments and notes.
9007 * device/examples/test2.c:
9008 Fix bug, "red" variable not being initialized(compiler complained).
