1456 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1457 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1458 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1459 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1460 always available in leading double underscore form. The C99 support is
1461 mostly missing, but it's a start.
1462 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1463 reserved identifier "__data".

1541 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1543 * device/lib/printf_large.c: removed inline assembly for portability and
1544 readability. Use printf_fast if speed or size are more important.
1545 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1546 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1548 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1550 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1551 prevent compiler warning
1553 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1555 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1556 moved to level 0 and declared as static. Also they are explicit
1557 placed in access bank. This was necessery because some times they
1558 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1559 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1560 optimizations. Currently only compare to unsigned char is implemented,
1561 * src/pic16/gen.c: added fReturnIdx array,
1562 * (struct resolvedIfx) is moved to gen.h and made public,
1563 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1564 * (aopForSym): added an optimization to directly store in stack of
1565 the operand of a SEND iCode,
1566 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1567 but as registers instead (AOP_REG) using the fReturnIdx array,
1568 * (pic16_freeAsmop): remove the freed register from the
1569 _G.sregsAlloc field,
1570 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1571 a compare of 'WREG',
1572 * (pic16_popGetTempRegCond): changed function prototype, now
1573 function takes also a bitVector argument v which holds the current
1574 set of registers that are allocated for stack access by aopForSym,
1575 registers allocated in aopForSym for accessing stack symbols are not
1576 any more part of the functions usedRegs field,
1577 * (genCall): some times aopOp is called for a stack variable to be
1578 send, aopForSym might perform the push, if this is true make sure
1579 that genCall doesn't push the variable twice by testing _G.resDirect,
1580 * (genFunction): changed testing for unspecified interrupt number
1581 from 256 to INTNO_UNSPEC,
1582 * modified selection scheme of frame pointer generation. Previously
1583 if function did use local registers a frame pointer was generated,
1584 now a frame pointer is generated only if function has arguments
1585 (that need PLUSW2 register access), or has stack arguments, or the
1586 compiler is not instructed to omit the frame pointer,
1587 * (genEndFunction): before restoring local registers that were saved
1588 in the function preamble, also restore the registers that *might*
1589 have been allocated for stack access,
1590 * (genRet): removed some old comments,
1591 * (genCmp, the active (RN's) version): added a call to the
1592 pic16_genCmp_special function to perform the compare with a more
1593 robust and optimized way,
1594 * (genInline): a feature has been added in inline code generation,
1595 which allows a wildcard variable substitution when writing inline
1596 assembly. Code is incomplete and experimental therefore undocumented,
1597 * (genCast): changed order of aopOp for result and right to allow
1598 aopForSym to directly load the result if possible,
1599 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1600 perform an optimized compare on some selected special occasions,
1601 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1602 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1603 generate an IVT any more,
1604 * src/pic16/main.c (pic16_optionsTable): added command line option
1606 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1607 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1609 * src/pic16/NOTES: Raphael Neider added in list of active developers
1610 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1611 jumptable_end to prevent bug #,
1612 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1613 inCond and outCond fields,
1614 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1615 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1616 turn off register spilling,
1617 * (packRegsForOneUse): synced with other ports' versions although it
1618 is not used currently,
1619 * (pic16_packRegisters): added an optimization while reading
1620 structure bitfields, some registers may be saved (malloc code is
1621 decreased by 80 bytes)
1623 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1625 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1626 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1627 this can be optimized more?
1629 2005-03-10 Raphael Neider <rneider AT web.de>
1631 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1632 genNearPointerGet): (hopefully) fixed access to bitfields via
1633 pointers (p->bitN = x; and x = p->bitN; failed)

2267 Adding support for replacing ljmps with sjmps in jumptables
2268 generated for switch statements. For now you need to set the
2269 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2270 Now 4 algorithms for mcs51 jumptable generation are used:
2271 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2272 addresses loaded pc-relative for up to 112 cases and stack-pushing
2273 target addresses loaded with offset from dptr for up to 256 cases.

2300 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2301 to call when a stack overflow occurs,
2302 * (malloc.h): added CVS Id tag,
2303 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2305 * added libc directory. The current version of LibC contains string
2306 functions, ctype functions and macros and some functions of the
2307 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2308 be extensively tested in the future. Standard disclaimer here.
2309 Library is not automatically build yet. But one can build it by
2310 invoking 'make' inside the libc directory.
2311 * added ADC library under libio. Preliminary version yet.

2320 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2321 * (pic16_storeForReturn): optimized return of 0,
2322 * (genCmp): experimental code for new genCmp which uses PIC18's
2323 special compare&skip instructions. Initial tests fail some times
2324 with variables grater than 1 byte in size, so new code is disabled,
2325 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2327 * (genCast): began a fix to optimize the casting of a bit to another
2328 bit, now assigning a bitfield to another bitfield will fail, sorry,
2329 * src/pic16/main.c: disabled the use of lr-support feature,
2330 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2333 bits with offset (case PO_GPR_BIT),
2334 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2336 * (isBankInstruction): modified to return 0 for no banking instruction,
2337 and 1 for banking instruction,
2338 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2339 caused stop processing pCodes after a inline assembly block,
2340 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2341 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2342 registers when it shouldn't,
2343 * src/pic16/ralloc.c (allocReg): add preliminary support for
2344 supporting a limited set of temporary registers,
2346 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2348 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2349 genDataPointerSet): ensure assignments always copy in MSB to LSB
2351 (loadRegFromAop): recognize CLRH optimization,
2352 (genFunction): optimize RECEIVE iCodes in reentrant functions
2354 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2356 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5257 * support/regression/generate-cases.py (main): Changed from inline
5260 * doc/Makefile (install): Changed to depth first to get rid of
5261 missing directory install warning.
5263 * as/Makefile (install-doc): Made work on Mac.
5265 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5267 * src/SDCCast.c: added an additional type flow in decorateType() of
5268 opposite direction, see feature request #860006; it's enabled at runtime
5269 by setting the environment variable SDCC_NEWTYPEFLOW
5270 * src/SDCCast.h: changed prototype of decorateType()
5271 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5272 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5273 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5274 see feature request #877103
5275 * src/SDCCval.c: updated call of decorateType()
5276 (valBitwise): fixed bug #882876
5277 (valMinus): added promotion
5278 (valLogicAndOr): result is unsigned
5279 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5280 * src/SDCCsymt.c (computeType),
5281 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5282 must not cause an unsigned operation
5283 * src/pic/glue (pic14emitRegularMap),
5284 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5286 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

5303 * src/pic/ralloc.h: applied patch from Slade Rich;
5304 added support for multiple code pages and multiple RAM banks on the
5305 PIC 14 port. The ASM files now no longer simply assume all the
5306 code / RAM are in the same page / bank. This means the linker can
5307 safely allocate code/RAM of separate ASM files to different pages/banks.
5308 * doc/sdccman.lyx: added Slade's tips
5309 * src/mcs51/peeph.def: fixed bug #880768

5318 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5321 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5322 strtof is not part of C89 and isn't included with Mac OS X.
5324 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5326 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5351 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5353 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5354 loaded with the linker search paths (-L arguments) and the libraries
5355 to be linked with the current source (-l arguments). Changes
5356 currently will affect only the pic16 port.
5357 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5358 include path the port specific paths and port specific libraries,
5359 * gplink command now contains the $3 argument,
5360 * src/pic16/device.h,
5361 * src/pic16/device.c,: structure PIC_device is made public and
5362 renamed to PIC16_device, the same for variable Pics which is renamed

5377 Documenting changes from previous commits.
5378 * configure.in (version 1.56),
5379 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5380 when generating output files to configure the pic16 library,
5381 but now I've commented it out, since gputils aren't installed in the
5382 SF compile farm, so library won't compile
5384 * device/lib/Makefile.in (version 1.56): initially I've added in
5385 target 'all' the prerequestive 'model-pic16' so it compiled the
5386 pic16 library, but now I've commented it out for the same reasons
5388 * added targets 'model-pic16' and 'objects-pic16' to compile the
5390 * added target 'port-specific-objects-pic16' to handle the
5391 generated libraries and copy them into the build/ directory
5392 * added target 'clean-intermediate-pic16' to clean intermediate
5393 files into pic16 directory
5394 * in target 'installdirs' added line to create directory pic16 in
5395 the installation path
5397 * device/include/Makefile.in (version 1.11): in target 'install'
5398 added lines to copy all header files to installation path,
5399 * in target 'installdirs' added line create directory for pic16
5400 headers in the installation path

5415 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5416 option so that it actually works. Made it specific to the z80, since
5417 the gbz80 doesn't have these kinds of I/O ports.
5419 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5421 * device/include/z180.h,

5443 Mainly changes to support compilation of the device libraries
5444 * src/pic16/device.c: stack is allocated via symbol and not
5445 via literal number. The symbol is placed in the corresponding
5446 position of the data ram
5447 * (pic16_dump_section): relocatable and absolute uninitialized
5448 data are now emitted in sorted order to reduce section naming,
5449 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5450 weren't marked as being in the access bank,
5452 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5454 Added portion of GNU PIC Library under the directory
5455 device/include/pic16 and device/lib/pic16. These files
5456 contain the declarations of SFRs for the PIC18Fxx2 devices.
5457 The directory is initialized via configure from toplevel.
5459 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5461 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5487 all over. Telling LaTeX to be less strict with word spacing
5488 to better keep the right margin. Changed some notes about
5489 maintainance of the ports in section 3.2.1 - is it OK like this?
5491 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5529 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5531 * src/pic16/peeph.def: all peepholes with movff are commented out,
5532 because there is a problem in the pcode peep optimizer,
5533 * src/pic16/ralloc.c: the register allocator can now reuse local

5672 Bug reported from Jesus Calvino-Fraga
5674 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5676 * sdcc.spec: updated
5677 * device/include/Makefile.in: don't install CVS directories

5680 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5681 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5682 * src/ds390/gen.c (genRightShift): fixed bug #870788
5683 * src/SDCCast.c (decorateType): fixed bug #870781
5685 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5687 PIC16 port related changes:
5688 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5689 added variable stackPos,
5691 * gen.c: genCall, assignResultValue: added support for
5692 pushing/retrieving function parameters to/from stack,
5693 genFunction,genEndFunction: setup stack frame for the
5695 genAddrOf: will be changed according to bug 863624
5697 * added files genutils.c and genutils.h which contain gen*
5698 debugged and optimised functions extracted from gen.c
5700 * glue.c: added variable 'externs' which holds extern symbols,
5701 pic16emitRegularMap: is modified to properly handle relocatable
5702 symbols under the new scheme,
5703 pic16createInterruptVect: is modified
5704 pic16printPublics: is modified to emit 'global' assembler directives,
5705 added pic16_printExterns to print extern symbols,
5706 pic16glue: initializes stack/frame pointer in the beginning of
5707 the assembly output. Temporary hack, will be corrected later,
5708 because gplink yet does not support stack and SDCC does not
5709 yet support a type of crt0.o object to create the final binary.
5711 * Removed many lines that contain 8051 legacy code.
5712 * The code is finally placed under a 'code' directive.
5713 * Added port specific options.
5715 * _process_pragma: simplified since now we do not need *special*
5716 include file to define SFR registers. But a separate header
5717 will be needed. This will be developed later.
5718 * _pic16_parseOptions: added, parses port specific options:
5719 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5720 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5721 --preplace-udata-with=
5723 * _pic16_setDefaultOptions: modified to initialize section names,
5724 but hack is temporarly out of order since it needs improvement.
5725 * _pic16_genAssemblerPreamble: configuration words are emitted by
5726 their address instead of their name. This part is incomplete and
5727 supports only the 18Fxx2 devices. Other devices will emit an error
5728 during assembly since they do not contain the same set of config
5730 * _pic16_genIVT: is modified,
5732 * pcode.c: added definitions for some hardware registers that are needed
5734 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5735 All PCI entries are updated. Now LFSR is supported.
5736 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5737 * added pic16_newpCodeOpLit2 to support instructions with
5738 two literal arguments
5739 * pic16_pCode2str: corrected code that emits assembler instructions
5740 with two literal operands and those that have an access bit modifier
5741 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5742 this fixes a bug which caused some labels to be lost, when an
5743 assembler directive was added, i.e. banksel,
5744 * pic16_FixRegisterBanking: improved logic that causes the insertion
5746 * InlineFunction: functions that are called once, are not any more
5747 inlined. This can be a port option in the future,
5749 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5751 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5752 hold the corresponding uninitialized symbols,
5753 * pic16_allocProcessorRegister: registers have explicit marked the
5755 * pic16_allocInternalRegister: registers are explicit marked as
5757 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5758 processing list, so bit registers were lost,
5761 * ralloc.h: added field 'accessBank' and original symbol operand
5762 in register definition,
5763 * removed the field isMapped from register definition,
5765 ** Several functions have been removed from various sources:
5766 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5767 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5768 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5769 pic16_assignRelocatableRegisters
5771 ** others have been introduced:
5772 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5773 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5775 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5777 * support/scripts/inc2h.pl: changed definition of BIT_AT
5778 to emit 'sbit at' instead of 'bit at'. This was a request.
5780 PIC16 port related preliminary changes:
5781 * gen.c: prefixed function popRegFromString with
5782 pic16_ and all references to it corrected
5783 * pcode.c: all pic16_pc_* hardware registers prefixed
5784 with underscore (_),
5785 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5786 * ralloc.c: newReg(): when register is REG_SFR then
5787 set address to rIdx,
5788 pic16_allocProcessorRegister(): marks register wasUsed=0
5789 pic16_writeUsedRegs(): added a call to assign processor
5790 registers via pic16_assignFixedRegisters
5792 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5794 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5795 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5796 variables in unused register banks. Also the SSEG is placed
5797 wherever there is enough space for it, and IDATA can be anywhere
5798 in internal RAM. For now compile using -Wl-Y[stack_size].
5799 The mem file is different for this option as well, since it
5800 makes no sense of talking about DSEG lenght.
5802 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5804 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6049 * src/SDCCast.c (decorateType): disabled a transformation I added in
6050 revision 1.188 (access to fields of a structure at an absolute address);
6051 it breaks with bitfields, extern declarations, and gcse analysis.
6052 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6053 could be assigned through a pointer, so don't complain.

6810 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6811 fetching of the pointer
6812 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6813 copied from genNearPointerSet()
6814 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6815 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6829 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6831 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6832 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6833 type for bits was changed. It resulted in bit variables becoming
6834 global, which is not permitted in PIC 14 assembly output.
6836 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6838 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6851 A few small changes that speed up the peephole optimizer.
6855 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6857 Try to make the peephole optimizer smarter by maintaining
6858 an association between the assembly source code and the
6859 iCodes that originated them. Put this information to use
6860 with a new peephole rule condition "notVolatile" so that
6861 the rules can be aggressive yet still safe.
6866 * src/mcs51/peeph.def
6868 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6872 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6873 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6874 if the left or right operand symbols have the accuse flag set.
6876 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6878 Changed the type of the result of the ! (NOT) operator to char;
6879 previously it returned the same type as the source. This allows
6880 us to eliminate all the genFloatNot functions (all of its target
6881 implementations were very buggy) since !float can use the same
6884 * src/SDCCicode.c (ast2iCode): ! returns char

6886 * src/ds390/gen.c (genNot, genNotFloat),
6887 * src/z80/gen.c (genNot, genNotFloat),
6888 * src/pic/gen.c (genNot, genNotFloat),

6891 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6893 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6894 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6895 during interrupts. Ensure WSAVE is located at a shared bank address.
6896 2. Fixed page selection in some places
6897 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6898 the registers name strings.
6899 4. Fixed "signed / unsigned compare" compiler warnings.
6900 5. The PIC port manages its own allocation of the general purpose
6901 registers, but makes no attempt to reuse them. As a result when
6902 compiling it soon runs out of general purpose registers. Some
6903 additional code was added to the files pcode.c and device.c to walk
6904 through the function call tree and rename the registers so that they
6914 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6915 genPlus() & genMinus() when the result is the same as left or right

6921 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6923 Made bitfield a distinct type from bit so that bitfields
6924 convert as per ANSI C and bits retain their traditional
6925 boolean style behaviour. Implemented bitfield support in
6933 * src/ds390/gen.c: bit v bitfield split
6934 * src/z80/gen.c: New support for bitfields
6935 * support/regression/tests/bitfields.c: reenabled z80,
6938 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6940 Rules 246.x, 247.x relate to bitfields, the others speed up
6941 access to xdata mapped I/O devices.
6943 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6945 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6947 Cleaned up genPackBits and genUnpackBits and added two helper
6948 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6949 for literal assignments in genPackBits (thanks to Frieder for
6955 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6957 Fixed bug #748310 (pointer to function type mishandled when the
6958 function name is omitted). Also fixed a SIGSEGV when a function
6959 attribute (reentrant, etc) is used on a non-function or on a
6960 function but misplaced before the parameter list.
6962 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6964 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6987 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6989 Made the constant following the "interrupt" keyword optional. If
6990 omitted, the function will not automatically be given an entry
6991 in the interrupt vector table (similar to #pragma NOIV, but
6992 less syntacticly kludgy). The interrupt number is also now
6993 range checked. Also fixed a bug in the high order bit example

7009 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7011 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7012 be re-activated by defining REDUCE_LITERALS)
7013 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7014 unsigned, but are signed by default
7015 * src/SDCCval.c (constVal): rearranged
7016 * src/SDCCval.c (valMod): preliminary fix
7017 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7469 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7470 the regression tests I'm not brave enough to enable 245.b, 245.c
7471 * doc/sdccman.lyx: added latex preamble for hyperref package.
7472 Using pdflatex this will give you a hyperlinked pdf file with
7473 bookmarks. (prepend '%' before /usepackage if this breaks something)

7511 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7513 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7514 it can be defined with CFLAGS when running configure
7515 * src/SDCCmain.c: fixed compiling + linking with object files
7517 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7520 added --disable-pic16-port
7521 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7522 * src/SDCCmain.c: linkOptions is changed to set *,
7523 added if/endif conditional macros to remove options help
7524 messages from optionsTable when a port is not configured, added
7525 support for the PIc16 port in the ports table, when executing
7526 the compiler with no port specified on command line, a default
7527 port is selected with the new macro DEFAULT_PORT which is
7528 defined in port.h, in setDefaultOptions() linkOptions is removed
7529 from initialization assignment, since now it is a set,
7530 parseCmdLine uses setParseWithComma for linkOptions, in
7531 linkEdit() linkOptions are accessed with new function indexSet()
7532 which returns the i'th item of a set variable. See SDCCset.c, in
7533 linkEdit() when calling buildCmdLine(), added linkOptions as
7534 last argument. Now users can pass arguments to gplink via the
7535 -Wl option, main() uses pic16glue() to glue up pic16 programs

7547 * src/pic16/glue.c: commented out some error producing lines
7548 * src/pic16/main.c: __config directives are commented out to stop
7549 gpasm complaining and test the linkage with gplink, _linkCmd and
7550 _asmCmd changed to be more gplink and gpasm friendly
7551 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7552 produced an error when parsed, peep rule 12 is added to utilize
7553 movff, but it is commented out since the pCode does not support
7554 yet a command with 2 address arguments
7556 2003-05-18 <johan AT balder>
7558 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7559 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7583 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7585 2003-05-11 Borut Razem <borut.razem AT siol.net>
7587 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7588 the path of bin directory, so that PATH is the only env. variable, which has to be set
7589 in case of standard installation.
7590 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8672 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8673 not bytes. Function summary() which creates a memory usage summary
8674 file with extension .mem. Reports of overlaping stack and small stack
8675 size. If the space for the stack is less than 16 bytes aslink trows a
8678 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8679 the 8051. Option 'y' for memory summary output file.
8681 Changes to sdcc (All the changes are marked with 'JCF'):
8683 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8685 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8686 overlaying area for it (uses RegBankUsed[4]).
8688 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8689 bank zero as used by default. By default aslink locates the stack
8690 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8691 the creation of the .mem file. Delegates the allocation of data area
8692 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8693 the begining of the stack area to aslink.
8695 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8696 glue() in SDCCglue.c creates an area for it.
8698 2002-09-03 Borut Razem <borut.razem AT siol.net>
8699 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8700 sdcc/src/pic/glue.c:
8701 introduced atexit() handler for teporay files removal in case of
8702 errors, assertions, ...
8704 2002-08-29 Borut Razem <borut.razem AT siol.net>
8705 * sdcc/support/cpp2/auto-host_vc_in.h:
8706 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8707 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8708 Maybe there is a similar problem with BORLANDC? It should be checked!
8710 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8711 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8712 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8713 was not executed, and the compiler (cl) launched a warning:
8714 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8716 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8717 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8719 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8720 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8722 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8723 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8724 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8725 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8726 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8727 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8728 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8729 - added Release configuration in VS projects
8730 - review of compiler an linker options
8731 - VC .exe files are generated in bin_vc directory, not to interfere
8732 with binaries generated from other projects (cygwin, mingw, bcc ...)
8734 * sdcc/src/yacc.dsp: added
8736 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8737 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8738 and insert the version number definitions from .version
8740 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8742 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8743 added - genarate auto-host.h using auto-host_vc_in.h as template
8746 removed from CVS, generated automatically
8748 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8749 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8751 2002-08-11 Borut Razem <borut.razem AT siol.net>
8752 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8754 2002-08-10 Borut Razem <borut.razem AT siol.net>
8755 * src/SDCCmain.c (main):
8756 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8757 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8758 The consequence was that some temporary files were not removed.
8761 unification of code in functions tempfilename() and tempfile():
8762 function tempnam() is defined in Visual Studio 6.0 and .NET
8764 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8766 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8767 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8768 - removed compiler command line option /WX: Treats all warnings as errors
8769 - update a list of source files, included into the project
8771 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8772 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8773 changed project type to Generic Project so that can be correcly converted to VS.NET project
8775 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8777 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8779 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8781 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8782 added return 0 statements after assert() to make compiler happy
8784 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8785 added newline in the def file to keep MSC compiler satisfied
8787 * sdcc/src/z80/gen.c:
8788 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8789 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8790 - solved MSC error in function aopDump()
8792 * sdcc_vc.h: define PREFIX as "\\sdcc"
8794 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8795 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8838 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8840 Added "char *Processor" field to the port structure.
8843 Added -p option. Allows port dependent processor to be specified.
8846 Initialized the new field char *Processor field to NULL in all ports
8849 Compiler generated registers for interrupt context saving
8850 were not getting allocated.
8852 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8855 Fixed left shift. Will promote the left side of a left shift
8856 if a) left shifting more than size of operand or b) when assigned
8857 to something size > size of left side
8859 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8861 tons of changes. Register allocation has been
8862 rewritten. Added customization for the various PICs. Flow

8967 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8969 * sdcc/src/SDCCloop.c:
8970 Previous fix was not good. basic blocks that have "break" or "return" are
8971 not really partof a loop , but live ranges used in these blocks should
8972 be live thru the entire loop, so set partOfLoop but don't add them to
8975 2002-02-21 <johan AT FRIJA>
8977 * src/SDCCcse.c: fixed bug #514308
8979 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8983 statement inside a loop, it was not being considered part of the loop.
8985 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8987 2002-02-10 Karl Bongers <karl AT turbobit.com>
8990 Fixed up SDCDB debugger somewhat. Updated debugger/README
8991 with lots of comments and notes.
