1446 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1447 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1448 always available in leading double underscore form. The C99 support is
1449 mostly missing, but it's a start.
1450 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1529 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1531 * device/lib/printf_large.c: removed inline assembly for portability and
1532 readability. Use printf_fast if speed or size are more important.
1533 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1534 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1536 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1538 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1539 prevent compiler warning
1541 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1543 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1544 moved to level 0 and declared as static. Also they are explicit
1545 placed in access bank. This was necessery because some times they
1546 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1547 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1548 optimizations. Currently only compare to unsigned char is implemented,
1549 * src/pic16/gen.c: added fReturnIdx array,
1550 * (struct resolvedIfx) is moved to gen.h and made public,
1551 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1552 * (aopForSym): added an optimization to directly store in stack of
1553 the operand of a SEND iCode,
1554 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1555 but as registers instead (AOP_REG) using the fReturnIdx array,
1556 * (pic16_freeAsmop): remove the freed register from the
1557 _G.sregsAlloc field,
1558 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1559 a compare of 'WREG',
1560 * (pic16_popGetTempRegCond): changed function prototype, now
1561 function takes also a bitVector argument v which holds the current
1562 set of registers that are allocated for stack access by aopForSym,
1563 registers allocated in aopForSym for accessing stack symbols are not
1564 any more part of the functions usedRegs field,
1565 * (genCall): some times aopOp is called for a stack variable to be
1566 send, aopForSym might perform the push, if this is true make sure
1567 that genCall doesn't push the variable twice by testing _G.resDirect,
1568 * (genFunction): changed testing for unspecified interrupt number
1569 from 256 to INTNO_UNSPEC,
1570 * modified selection scheme of frame pointer generation. Previously
1571 if function did use local registers a frame pointer was generated,
1572 now a frame pointer is generated only if function has arguments
1573 (that need PLUSW2 register access), or has stack arguments, or the
1574 compiler is not instructed to omit the frame pointer,
1575 * (genEndFunction): before restoring local registers that were saved
1576 in the function preamble, also restore the registers that *might*
1577 have been allocated for stack access,
1578 * (genRet): removed some old comments,
1579 * (genCmp, the active (RN's) version): added a call to the
1580 pic16_genCmp_special function to perform the compare with a more
1581 robust and optimized way,
1582 * (genInline): a feature has been added in inline code generation,
1583 which allows a wildcard variable substitution when writing inline
1584 assembly. Code is incomplete and experimental therefore undocumented,
1585 * (genCast): changed order of aopOp for result and right to allow
1586 aopForSym to directly load the result if possible,
1587 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1588 perform an optimized compare on some selected special occasions,
1589 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1590 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1591 generate an IVT any more,
1592 * src/pic16/main.c (pic16_optionsTable): added command line option
1594 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1595 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1597 * src/pic16/NOTES: Raphael Neider added in list of active developers
1598 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1599 jumptable_end to prevent bug #,
1600 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1601 inCond and outCond fields,
1602 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1603 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1604 turn off register spilling,
1605 * (packRegsForOneUse): synced with other ports' versions although it
1606 is not used currently,
1607 * (pic16_packRegisters): added an optimization while reading
1608 structure bitfields, some registers may be saved (malloc code is
1609 decreased by 80 bytes)
1611 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1613 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1614 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1615 this can be optimized more?
1617 2005-03-10 Raphael Neider <rneider AT web.de>
1619 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1620 genNearPointerGet): (hopefully) fixed access to bitfields via
1621 pointers (p->bitN = x; and x = p->bitN; failed)

2255 Adding support for replacing ljmps with sjmps in jumptables
2256 generated for switch statements. For now you need to set the
2257 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2258 Now 4 algorithms for mcs51 jumptable generation are used:
2259 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2260 addresses loaded pc-relative for up to 112 cases and stack-pushing
2261 target addresses loaded with offset from dptr for up to 256 cases.

2288 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2289 to call when a stack overflow occurs,
2290 * (malloc.h): added CVS Id tag,
2291 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2293 * added libc directory. The current version of LibC contains string
2294 functions, ctype functions and macros and some functions of the
2295 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2296 be extensively tested in the future. Standard disclaimer here.
2297 Library is not automatically build yet. But one can build it by
2298 invoking 'make' inside the libc directory.
2299 * added ADC library under libio. Preliminary version yet.
2301 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2305 temporary registers, its a buggy feature and will be removed,
2306 * (pic16_popGet): set register instance field in AOP_CRY,
2307 * (pic16_outBitC): fixed for results in size greater than 1,
2308 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2309 * (pic16_storeForReturn): optimized return of 0,
2310 * (genCmp): experimental code for new genCmp which uses PIC18's
2311 special compare&skip instructions. Initial tests fail some times
2312 with variables grater than 1 byte in size, so new code is disabled,
2313 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2315 * (genCast): began a fix to optimize the casting of a bit to another
2316 bit, now assigning a bitfield to another bitfield will fail, sorry,
2317 * src/pic16/main.c: disabled the use of lr-support feature,
2318 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2321 bits with offset (case PO_GPR_BIT),
2322 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2324 * (isBankInstruction): modified to return 0 for no banking instruction,
2325 and 1 for banking instruction,
2326 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2327 caused stop processing pCodes after a inline assembly block,
2328 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2329 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2330 registers when it shouldn't,
2331 * src/pic16/ralloc.c (allocReg): add preliminary support for
2332 supporting a limited set of temporary registers,
2334 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2336 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2337 genDataPointerSet): ensure assignments always copy in MSB to LSB
2339 (loadRegFromAop): recognize CLRH optimization,
2340 (genFunction): optimize RECEIVE iCodes in reentrant functions
2342 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2344 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5259 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5260 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5261 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5262 see feature request #877103
5263 * src/SDCCval.c: updated call of decorateType()
5264 (valBitwise): fixed bug #882876
5265 (valMinus): added promotion
5266 (valLogicAndOr): result is unsigned
5267 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5268 * src/SDCCsymt.c (computeType),
5269 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5270 must not cause an unsigned operation
5271 * src/pic/glue (pic14emitRegularMap),
5272 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5274 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

5291 * src/pic/ralloc.h: applied patch from Slade Rich;
5292 added support for multiple code pages and multiple RAM banks on the
5293 PIC 14 port. The ASM files now no longer simply assume all the
5294 code / RAM are in the same page / bank. This means the linker can
5295 safely allocate code/RAM of separate ASM files to different pages/banks.
5296 * doc/sdccman.lyx: added Slade's tips
5297 * src/mcs51/peeph.def: fixed bug #880768

5339 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5341 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5342 loaded with the linker search paths (-L arguments) and the libraries
5343 to be linked with the current source (-l arguments). Changes
5344 currently will affect only the pic16 port.
5345 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5346 include path the port specific paths and port specific libraries,
5347 * gplink command now contains the $3 argument,
5348 * src/pic16/device.h,
5349 * src/pic16/device.c,: structure PIC_device is made public and
5350 renamed to PIC16_device, the same for variable Pics which is renamed

5363 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5365 Documenting changes from previous commits.
5366 * configure.in (version 1.56),
5367 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5368 when generating output files to configure the pic16 library,
5369 but now I've commented it out, since gputils aren't installed in the
5370 SF compile farm, so library won't compile
5372 * device/lib/Makefile.in (version 1.56): initially I've added in
5373 target 'all' the prerequestive 'model-pic16' so it compiled the
5374 pic16 library, but now I've commented it out for the same reasons
5376 * added targets 'model-pic16' and 'objects-pic16' to compile the
5378 * added target 'port-specific-objects-pic16' to handle the
5379 generated libraries and copy them into the build/ directory
5380 * added target 'clean-intermediate-pic16' to clean intermediate
5381 files into pic16 directory
5382 * in target 'installdirs' added line to create directory pic16 in
5383 the installation path
5385 * device/include/Makefile.in (version 1.11): in target 'install'
5386 added lines to copy all header files to installation path,
5387 * in target 'installdirs' added line create directory for pic16
5388 headers in the installation path

5403 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5404 option so that it actually works. Made it specific to the z80, since
5405 the gbz80 doesn't have these kinds of I/O ports.
5407 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5409 * device/include/z180.h,

5431 Mainly changes to support compilation of the device libraries
5432 * src/pic16/device.c: stack is allocated via symbol and not
5433 via literal number. The symbol is placed in the corresponding
5434 position of the data ram
5435 * (pic16_dump_section): relocatable and absolute uninitialized
5436 data are now emitted in sorted order to reduce section naming,
5437 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5438 weren't marked as being in the access bank,
5440 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5442 Added portion of GNU PIC Library under the directory
5443 device/include/pic16 and device/lib/pic16. These files
5444 contain the declarations of SFRs for the PIC18Fxx2 devices.
5445 The directory is initialized via configure from toplevel.
5447 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5449 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5461 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5463 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5464 in simpler and even better code

5475 all over. Telling LaTeX to be less strict with word spacing
5476 to better keep the right margin. Changed some notes about
5477 maintainance of the ports in section 3.2.1 - is it OK like this?
5479 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5517 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5519 * src/pic16/peeph.def: all peepholes with movff are commented out,
5520 because there is a problem in the pcode peep optimizer,
5521 * src/pic16/ralloc.c: the register allocator can now reuse local

5660 Bug reported from Jesus Calvino-Fraga
5662 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5664 * sdcc.spec: updated
5665 * device/include/Makefile.in: don't install CVS directories

5670 * src/ds390/gen.c (genRightShift): fixed bug #870788
5671 * src/SDCCast.c (decorateType): fixed bug #870781
5673 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5675 PIC16 port related changes:
5676 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5677 added variable stackPos,
5679 * gen.c: genCall, assignResultValue: added support for
5680 pushing/retrieving function parameters to/from stack,
5681 genFunction,genEndFunction: setup stack frame for the
5683 genAddrOf: will be changed according to bug 863624
5685 * added files genutils.c and genutils.h which contain gen*
5686 debugged and optimised functions extracted from gen.c
5688 * glue.c: added variable 'externs' which holds extern symbols,
5689 pic16emitRegularMap: is modified to properly handle relocatable
5690 symbols under the new scheme,
5691 pic16createInterruptVect: is modified
5692 pic16printPublics: is modified to emit 'global' assembler directives,
5693 added pic16_printExterns to print extern symbols,
5694 pic16glue: initializes stack/frame pointer in the beginning of
5695 the assembly output. Temporary hack, will be corrected later,
5696 because gplink yet does not support stack and SDCC does not
5697 yet support a type of crt0.o object to create the final binary.
5699 * Removed many lines that contain 8051 legacy code.
5700 * The code is finally placed under a 'code' directive.
5701 * Added port specific options.
5703 * _process_pragma: simplified since now we do not need *special*
5704 include file to define SFR registers. But a separate header
5705 will be needed. This will be developed later.
5706 * _pic16_parseOptions: added, parses port specific options:
5707 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5708 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5709 --preplace-udata-with=
5711 * _pic16_setDefaultOptions: modified to initialize section names,
5712 but hack is temporarly out of order since it needs improvement.
5713 * _pic16_genAssemblerPreamble: configuration words are emitted by
5714 their address instead of their name. This part is incomplete and
5715 supports only the 18Fxx2 devices. Other devices will emit an error
5716 during assembly since they do not contain the same set of config
5718 * _pic16_genIVT: is modified,
5720 * pcode.c: added definitions for some hardware registers that are needed
5722 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5723 All PCI entries are updated. Now LFSR is supported.
5724 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5725 * added pic16_newpCodeOpLit2 to support instructions with
5726 two literal arguments
5727 * pic16_pCode2str: corrected code that emits assembler instructions
5728 with two literal operands and those that have an access bit modifier
5729 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5730 this fixes a bug which caused some labels to be lost, when an
5731 assembler directive was added, i.e. banksel,
5732 * pic16_FixRegisterBanking: improved logic that causes the insertion
5734 * InlineFunction: functions that are called once, are not any more
5735 inlined. This can be a port option in the future,
5737 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5739 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5740 hold the corresponding uninitialized symbols,
5741 * pic16_allocProcessorRegister: registers have explicit marked the
5743 * pic16_allocInternalRegister: registers are explicit marked as
5745 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5746 processing list, so bit registers were lost,
5749 * ralloc.h: added field 'accessBank' and original symbol operand
5750 in register definition,
5751 * removed the field isMapped from register definition,
5753 ** Several functions have been removed from various sources:

5763 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5765 * support/scripts/inc2h.pl: changed definition of BIT_AT
5766 to emit 'sbit at' instead of 'bit at'. This was a request.
5768 PIC16 port related preliminary changes:
5769 * gen.c: prefixed function popRegFromString with
5770 pic16_ and all references to it corrected
5771 * pcode.c: all pic16_pc_* hardware registers prefixed
5772 with underscore (_),
5773 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5774 * ralloc.c: newReg(): when register is REG_SFR then
5775 set address to rIdx,
5776 pic16_allocProcessorRegister(): marks register wasUsed=0
5777 pic16_writeUsedRegs(): added a call to assign processor
5778 registers via pic16_assignFixedRegisters
5780 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5782 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5783 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5784 variables in unused register banks. Also the SSEG is placed
5785 wherever there is enough space for it, and IDATA can be anywhere
5786 in internal RAM. For now compile using -Wl-Y[stack_size].
5787 The mem file is different for this option as well, since it
5788 makes no sense of talking about DSEG lenght.
5790 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5792 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6039 it breaks with bitfields, extern declarations, and gcse analysis.
6040 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6041 could be assigned through a pointer, so don't complain.

6785 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
6786 iCode properly now. Use getSize instead of nRegs since a & b
6787 aren't part of the nRegs tally.
6789 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
6791 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

6798 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6799 fetching of the pointer
6800 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6801 copied from genNearPointerSet()
6802 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6803 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6804 If they pop r0/r1 they must be called in the opposite order than aopOp().
6805 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6806 (resp. --stack-auto), prepared for --xstack

6817 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6819 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6820 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6821 type for bits was changed. It resulted in bit variables becoming
6822 global, which is not permitted in PIC 14 assembly output.
6824 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6826 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6839 A few small changes that speed up the peephole optimizer.
6843 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6845 Try to make the peephole optimizer smarter by maintaining
6846 an association between the assembly source code and the
6847 iCodes that originated them. Put this information to use
6848 with a new peephole rule condition "notVolatile" so that
6849 the rules can be aggressive yet still safe.
6854 * src/mcs51/peeph.def
6856 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6860 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6861 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6862 if the left or right operand symbols have the accuse flag set.
6864 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6866 Changed the type of the result of the ! (NOT) operator to char;
6867 previously it returned the same type as the source. This allows
6868 us to eliminate all the genFloatNot functions (all of its target
6869 implementations were very buggy) since !float can use the same
6872 * src/SDCCicode.c (ast2iCode): ! returns char

6874 * src/ds390/gen.c (genNot, genNotFloat),
6875 * src/z80/gen.c (genNot, genNotFloat),
6876 * src/pic/gen.c (genNot, genNotFloat),

6879 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6881 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6882 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6883 during interrupts. Ensure WSAVE is located at a shared bank address.
6884 2. Fixed page selection in some places
6885 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6886 the registers name strings.
6887 4. Fixed "signed / unsigned compare" compiler warnings.
6888 5. The PIC port manages its own allocation of the general purpose
6889 registers, but makes no attempt to reuse them. As a result when
6890 compiling it soon runs out of general purpose registers. Some
6891 additional code was added to the files pcode.c and device.c to walk
6892 through the function call tree and rename the registers so that they
6902 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6903 genPlus() & genMinus() when the result is the same as left or right

6909 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6911 Made bitfield a distinct type from bit so that bitfields
6912 convert as per ANSI C and bits retain their traditional
6913 boolean style behaviour. Implemented bitfield support in
6921 * src/ds390/gen.c: bit v bitfield split
6922 * src/z80/gen.c: New support for bitfields
6923 * support/regression/tests/bitfields.c: reenabled z80,
6926 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6928 Rules 246.x, 247.x relate to bitfields, the others speed up
6929 access to xdata mapped I/O devices.
6931 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6933 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6935 Cleaned up genPackBits and genUnpackBits and added two helper
6936 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6937 for literal assignments in genPackBits (thanks to Frieder for
6943 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6945 Fixed bug #748310 (pointer to function type mishandled when the
6946 function name is omitted). Also fixed a SIGSEGV when a function
6947 attribute (reentrant, etc) is used on a non-function or on a
6948 function but misplaced before the parameter list.
6950 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6952 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6975 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6977 Made the constant following the "interrupt" keyword optional. If
6978 omitted, the function will not automatically be given an entry
6979 in the interrupt vector table (similar to #pragma NOIV, but
6980 less syntacticly kludgy). The interrupt number is also now
6981 range checked. Also fixed a bug in the high order bit example
6988 * support/Util/SDCCerr.c
6989 * support/Util/SDCCerr.h
6992 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6995 * src/SDCCicode.c (operandOperation): rewritten some ops
6996 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6997 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6999 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7000 be re-activated by defining REDUCE_LITERALS)
7001 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7002 unsigned, but are signed by default
7003 * src/SDCCval.c (constVal): rearranged
7004 * src/SDCCval.c (valMod): preliminary fix
7005 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7460 Using pdflatex this will give you a hyperlinked pdf file with
7461 bookmarks. (prepend '%' before /usepackage if this breaks something)

7502 it can be defined with CFLAGS when running configure
7503 * src/SDCCmain.c: fixed compiling + linking with object files
7505 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7510 * src/SDCCmain.c: linkOptions is changed to set *,
7511 added if/endif conditional macros to remove options help
7512 messages from optionsTable when a port is not configured, added
7513 support for the PIc16 port in the ports table, when executing
7514 the compiler with no port specified on command line, a default
7515 port is selected with the new macro DEFAULT_PORT which is
7516 defined in port.h, in setDefaultOptions() linkOptions is removed
7517 from initialization assignment, since now it is a set,
7518 parseCmdLine uses setParseWithComma for linkOptions, in
7519 linkEdit() linkOptions are accessed with new function indexSet()
7520 which returns the i'th item of a set variable. See SDCCset.c, in
7521 linkEdit() when calling buildCmdLine(), added linkOptions as
7522 last argument. Now users can pass arguments to gplink via the
7523 -Wl option, main() uses pic16glue() to glue up pic16 programs

7535 * src/pic16/glue.c: commented out some error producing lines
7536 * src/pic16/main.c: __config directives are commented out to stop
7537 gpasm complaining and test the linkage with gplink, _linkCmd and
7538 _asmCmd changed to be more gplink and gpasm friendly
7539 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7540 produced an error when parsed, peep rule 12 is added to utilize
7541 movff, but it is commented out since the pCode does not support
7542 yet a command with 2 address arguments
7544 2003-05-18 <johan AT balder>
7546 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7573 2003-05-11 Borut Razem <borut.razem AT siol.net>
7575 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7576 the path of bin directory, so that PATH is the only env. variable, which has to be set
7577 in case of standard installation.

8671 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8673 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8674 overlaying area for it (uses RegBankUsed[4]).
8676 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8677 bank zero as used by default. By default aslink locates the stack
8678 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8679 the creation of the .mem file. Delegates the allocation of data area
8680 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8681 the begining of the stack area to aslink.
8683 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8684 glue() in SDCCglue.c creates an area for it.
8686 2002-09-03 Borut Razem <borut.razem AT siol.net>
8687 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8688 sdcc/src/pic/glue.c:
8689 introduced atexit() handler for teporay files removal in case of
8690 errors, assertions, ...
8692 2002-08-29 Borut Razem <borut.razem AT siol.net>
8693 * sdcc/support/cpp2/auto-host_vc_in.h:
8694 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8695 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8696 Maybe there is a similar problem with BORLANDC? It should be checked!
8698 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8699 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8700 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8701 was not executed, and the compiler (cl) launched a warning:
8702 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8704 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8705 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8707 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8708 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8710 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8711 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8712 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8713 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8714 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8715 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8716 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8717 - added Release configuration in VS projects
8718 - review of compiler an linker options
8719 - VC .exe files are generated in bin_vc directory, not to interfere
8720 with binaries generated from other projects (cygwin, mingw, bcc ...)
8722 * sdcc/src/yacc.dsp: added
8724 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8725 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8726 and insert the version number definitions from .version
8728 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8730 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8731 added - genarate auto-host.h using auto-host_vc_in.h as template
8734 removed from CVS, generated automatically
8736 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8737 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8739 2002-08-11 Borut Razem <borut.razem AT siol.net>
8740 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8742 2002-08-10 Borut Razem <borut.razem AT siol.net>
8743 * src/SDCCmain.c (main):
8744 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8745 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8746 The consequence was that some temporary files were not removed.
8749 unification of code in functions tempfilename() and tempfile():
8750 function tempnam() is defined in Visual Studio 6.0 and .NET
8752 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8754 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8755 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8756 - removed compiler command line option /WX: Treats all warnings as errors
8757 - update a list of source files, included into the project
8759 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8760 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8761 changed project type to Generic Project so that can be correcly converted to VS.NET project
8763 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8765 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8767 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8769 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8770 added return 0 statements after assert() to make compiler happy
8772 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8773 added newline in the def file to keep MSC compiler satisfied
8775 * sdcc/src/z80/gen.c:
8776 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8777 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8778 - solved MSC error in function aopDump()
8780 * sdcc_vc.h: define PREFIX as "\\sdcc"
8782 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8783 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8831 Added -p option. Allows port dependent processor to be specified.
8834 Initialized the new field char *Processor field to NULL in all ports
8837 Compiler generated registers for interrupt context saving
8838 were not getting allocated.
8840 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8843 Fixed left shift. Will promote the left side of a left shift
8844 if a) left shifting more than size of operand or b) when assigned
8845 to something size > size of left side
8847 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8957 * sdcc/src/SDCCloop.c:
8958 Previous fix was not good. basic blocks that have "break" or "return" are
8959 not really partof a loop , but live ranges used in these blocks should
8960 be live thru the entire loop, so set partOfLoop but don't add them to
8963 2002-02-21 <johan AT FRIJA>
8965 * src/SDCCcse.c: fixed bug #514308
8967 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
