1451 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1452 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1453 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1454 always available in leading double underscore form. The C99 support is
1455 mostly missing, but it's a start.
1456 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1535 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1537 * device/lib/printf_large.c: removed inline assembly for portability and
1538 readability. Use printf_fast if speed or size are more important.
1539 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1540 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1542 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1544 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1545 prevent compiler warning
1547 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1549 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1550 moved to level 0 and declared as static. Also they are explicit
1551 placed in access bank. This was necessery because some times they
1552 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1553 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1554 optimizations. Currently only compare to unsigned char is implemented,
1555 * src/pic16/gen.c: added fReturnIdx array,
1556 * (struct resolvedIfx) is moved to gen.h and made public,
1557 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1558 * (aopForSym): added an optimization to directly store in stack of
1559 the operand of a SEND iCode,
1560 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1561 but as registers instead (AOP_REG) using the fReturnIdx array,
1562 * (pic16_freeAsmop): remove the freed register from the
1563 _G.sregsAlloc field,
1564 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1565 a compare of 'WREG',
1566 * (pic16_popGetTempRegCond): changed function prototype, now
1567 function takes also a bitVector argument v which holds the current
1568 set of registers that are allocated for stack access by aopForSym,
1569 registers allocated in aopForSym for accessing stack symbols are not
1570 any more part of the functions usedRegs field,
1571 * (genCall): some times aopOp is called for a stack variable to be
1572 send, aopForSym might perform the push, if this is true make sure
1573 that genCall doesn't push the variable twice by testing _G.resDirect,
1574 * (genFunction): changed testing for unspecified interrupt number
1575 from 256 to INTNO_UNSPEC,
1576 * modified selection scheme of frame pointer generation. Previously
1577 if function did use local registers a frame pointer was generated,
1578 now a frame pointer is generated only if function has arguments
1579 (that need PLUSW2 register access), or has stack arguments, or the
1580 compiler is not instructed to omit the frame pointer,
1581 * (genEndFunction): before restoring local registers that were saved
1582 in the function preamble, also restore the registers that *might*
1583 have been allocated for stack access,
1584 * (genRet): removed some old comments,
1585 * (genCmp, the active (RN's) version): added a call to the
1586 pic16_genCmp_special function to perform the compare with a more
1587 robust and optimized way,
1588 * (genInline): a feature has been added in inline code generation,
1589 which allows a wildcard variable substitution when writing inline
1590 assembly. Code is incomplete and experimental therefore undocumented,
1591 * (genCast): changed order of aopOp for result and right to allow
1592 aopForSym to directly load the result if possible,
1593 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1594 perform an optimized compare on some selected special occasions,
1595 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1596 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1597 generate an IVT any more,
1598 * src/pic16/main.c (pic16_optionsTable): added command line option
1600 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1601 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1603 * src/pic16/NOTES: Raphael Neider added in list of active developers
1604 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1605 jumptable_end to prevent bug #,
1606 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1607 inCond and outCond fields,
1608 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1609 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1610 turn off register spilling,
1611 * (packRegsForOneUse): synced with other ports' versions although it
1612 is not used currently,
1613 * (pic16_packRegisters): added an optimization while reading
1614 structure bitfields, some registers may be saved (malloc code is
1615 decreased by 80 bytes)
1617 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1619 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1620 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1621 this can be optimized more?
1623 2005-03-10 Raphael Neider <rneider AT web.de>
1625 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1626 genNearPointerGet): (hopefully) fixed access to bitfields via
1627 pointers (p->bitN = x; and x = p->bitN; failed)

2261 Adding support for replacing ljmps with sjmps in jumptables
2262 generated for switch statements. For now you need to set the
2263 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2264 Now 4 algorithms for mcs51 jumptable generation are used:
2265 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2266 addresses loaded pc-relative for up to 112 cases and stack-pushing
2267 target addresses loaded with offset from dptr for up to 256 cases.

2294 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2295 to call when a stack overflow occurs,
2296 * (malloc.h): added CVS Id tag,
2297 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2299 * added libc directory. The current version of LibC contains string
2300 functions, ctype functions and macros and some functions of the
2301 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2302 be extensively tested in the future. Standard disclaimer here.
2303 Library is not automatically build yet. But one can build it by
2304 invoking 'make' inside the libc directory.
2305 * added ADC library under libio. Preliminary version yet.
2307 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2314 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2315 * (pic16_storeForReturn): optimized return of 0,
2316 * (genCmp): experimental code for new genCmp which uses PIC18's
2317 special compare&skip instructions. Initial tests fail some times
2318 with variables grater than 1 byte in size, so new code is disabled,
2319 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2321 * (genCast): began a fix to optimize the casting of a bit to another
2322 bit, now assigning a bitfield to another bitfield will fail, sorry,
2323 * src/pic16/main.c: disabled the use of lr-support feature,
2324 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2327 bits with offset (case PO_GPR_BIT),
2328 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2330 * (isBankInstruction): modified to return 0 for no banking instruction,
2331 and 1 for banking instruction,
2332 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2333 caused stop processing pCodes after a inline assembly block,
2334 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2335 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2336 registers when it shouldn't,
2337 * src/pic16/ralloc.c (allocReg): add preliminary support for
2338 supporting a limited set of temporary registers,
2340 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2342 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2343 genDataPointerSet): ensure assignments always copy in MSB to LSB
2345 (loadRegFromAop): recognize CLRH optimization,
2346 (genFunction): optimize RECEIVE iCodes in reentrant functions
2348 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2350 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5264 * src/SDCCast.h: changed prototype of decorateType()
5265 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5266 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5267 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5268 see feature request #877103
5269 * src/SDCCval.c: updated call of decorateType()
5270 (valBitwise): fixed bug #882876
5271 (valMinus): added promotion
5272 (valLogicAndOr): result is unsigned
5273 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5274 * src/SDCCsymt.c (computeType),
5275 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5276 must not cause an unsigned operation
5277 * src/pic/glue (pic14emitRegularMap),
5278 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5280 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

5297 * src/pic/ralloc.h: applied patch from Slade Rich;
5298 added support for multiple code pages and multiple RAM banks on the
5299 PIC 14 port. The ASM files now no longer simply assume all the
5300 code / RAM are in the same page / bank. This means the linker can
5301 safely allocate code/RAM of separate ASM files to different pages/banks.
5302 * doc/sdccman.lyx: added Slade's tips
5303 * src/mcs51/peeph.def: fixed bug #880768

5315 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5316 strtof is not part of C89 and isn't included with Mac OS X.
5318 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5320 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5345 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5347 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5348 loaded with the linker search paths (-L arguments) and the libraries
5349 to be linked with the current source (-l arguments). Changes
5350 currently will affect only the pic16 port.
5351 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5352 include path the port specific paths and port specific libraries,
5353 * gplink command now contains the $3 argument,
5354 * src/pic16/device.h,
5355 * src/pic16/device.c,: structure PIC_device is made public and
5356 renamed to PIC16_device, the same for variable Pics which is renamed

5371 Documenting changes from previous commits.
5372 * configure.in (version 1.56),
5373 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5374 when generating output files to configure the pic16 library,
5375 but now I've commented it out, since gputils aren't installed in the
5376 SF compile farm, so library won't compile
5378 * device/lib/Makefile.in (version 1.56): initially I've added in
5379 target 'all' the prerequestive 'model-pic16' so it compiled the
5380 pic16 library, but now I've commented it out for the same reasons
5382 * added targets 'model-pic16' and 'objects-pic16' to compile the
5384 * added target 'port-specific-objects-pic16' to handle the
5385 generated libraries and copy them into the build/ directory
5386 * added target 'clean-intermediate-pic16' to clean intermediate
5387 files into pic16 directory
5388 * in target 'installdirs' added line to create directory pic16 in
5389 the installation path
5391 * device/include/Makefile.in (version 1.11): in target 'install'
5392 added lines to copy all header files to installation path,
5393 * in target 'installdirs' added line create directory for pic16
5394 headers in the installation path

5409 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5410 option so that it actually works. Made it specific to the z80, since
5411 the gbz80 doesn't have these kinds of I/O ports.
5413 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5415 * device/include/z180.h,

5437 Mainly changes to support compilation of the device libraries
5438 * src/pic16/device.c: stack is allocated via symbol and not
5439 via literal number. The symbol is placed in the corresponding
5440 position of the data ram
5441 * (pic16_dump_section): relocatable and absolute uninitialized
5442 data are now emitted in sorted order to reduce section naming,
5443 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5444 weren't marked as being in the access bank,
5446 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5448 Added portion of GNU PIC Library under the directory
5449 device/include/pic16 and device/lib/pic16. These files
5450 contain the declarations of SFRs for the PIC18Fxx2 devices.
5451 The directory is initialized via configure from toplevel.
5453 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5455 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5481 all over. Telling LaTeX to be less strict with word spacing
5482 to better keep the right margin. Changed some notes about
5483 maintainance of the ports in section 3.2.1 - is it OK like this?
5485 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5523 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5525 * src/pic16/peeph.def: all peepholes with movff are commented out,
5526 because there is a problem in the pcode peep optimizer,
5527 * src/pic16/ralloc.c: the register allocator can now reuse local

5679 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5681 PIC16 port related changes:
5682 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5683 added variable stackPos,
5685 * gen.c: genCall, assignResultValue: added support for
5686 pushing/retrieving function parameters to/from stack,
5687 genFunction,genEndFunction: setup stack frame for the
5689 genAddrOf: will be changed according to bug 863624
5691 * added files genutils.c and genutils.h which contain gen*
5692 debugged and optimised functions extracted from gen.c
5694 * glue.c: added variable 'externs' which holds extern symbols,
5695 pic16emitRegularMap: is modified to properly handle relocatable
5696 symbols under the new scheme,
5697 pic16createInterruptVect: is modified
5698 pic16printPublics: is modified to emit 'global' assembler directives,
5699 added pic16_printExterns to print extern symbols,
5700 pic16glue: initializes stack/frame pointer in the beginning of
5701 the assembly output. Temporary hack, will be corrected later,
5702 because gplink yet does not support stack and SDCC does not
5703 yet support a type of crt0.o object to create the final binary.
5705 * Removed many lines that contain 8051 legacy code.
5706 * The code is finally placed under a 'code' directive.
5707 * Added port specific options.
5709 * _process_pragma: simplified since now we do not need *special*
5710 include file to define SFR registers. But a separate header
5711 will be needed. This will be developed later.
5712 * _pic16_parseOptions: added, parses port specific options:
5713 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5714 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5715 --preplace-udata-with=
5717 * _pic16_setDefaultOptions: modified to initialize section names,
5718 but hack is temporarly out of order since it needs improvement.
5719 * _pic16_genAssemblerPreamble: configuration words are emitted by
5720 their address instead of their name. This part is incomplete and
5721 supports only the 18Fxx2 devices. Other devices will emit an error
5722 during assembly since they do not contain the same set of config
5724 * _pic16_genIVT: is modified,
5726 * pcode.c: added definitions for some hardware registers that are needed
5728 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5729 All PCI entries are updated. Now LFSR is supported.
5730 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5731 * added pic16_newpCodeOpLit2 to support instructions with
5732 two literal arguments
5733 * pic16_pCode2str: corrected code that emits assembler instructions
5734 with two literal operands and those that have an access bit modifier
5735 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5736 this fixes a bug which caused some labels to be lost, when an
5737 assembler directive was added, i.e. banksel,
5738 * pic16_FixRegisterBanking: improved logic that causes the insertion
5740 * InlineFunction: functions that are called once, are not any more
5741 inlined. This can be a port option in the future,
5743 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5745 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5746 hold the corresponding uninitialized symbols,
5747 * pic16_allocProcessorRegister: registers have explicit marked the
5749 * pic16_allocInternalRegister: registers are explicit marked as
5751 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5752 processing list, so bit registers were lost,
5755 * ralloc.h: added field 'accessBank' and original symbol operand
5756 in register definition,
5757 * removed the field isMapped from register definition,
5759 ** Several functions have been removed from various sources:

5769 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5771 * support/scripts/inc2h.pl: changed definition of BIT_AT
5772 to emit 'sbit at' instead of 'bit at'. This was a request.
5774 PIC16 port related preliminary changes:
5775 * gen.c: prefixed function popRegFromString with
5776 pic16_ and all references to it corrected
5777 * pcode.c: all pic16_pc_* hardware registers prefixed
5778 with underscore (_),
5779 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5780 * ralloc.c: newReg(): when register is REG_SFR then
5781 set address to rIdx,
5782 pic16_allocProcessorRegister(): marks register wasUsed=0
5783 pic16_writeUsedRegs(): added a call to assign processor
5784 registers via pic16_assignFixedRegisters
5786 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5788 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5789 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5790 variables in unused register banks. Also the SSEG is placed
5791 wherever there is enough space for it, and IDATA can be anywhere
5792 in internal RAM. For now compile using -Wl-Y[stack_size].
5793 The mem file is different for this option as well, since it
5794 makes no sense of talking about DSEG lenght.
5796 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5798 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6045 it breaks with bitfields, extern declarations, and gcse analysis.
6046 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6047 could be assigned through a pointer, so don't complain.

6791 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
6792 iCode properly now. Use getSize instead of nRegs since a & b
6793 aren't part of the nRegs tally.
6795 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
6797 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

6803 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6804 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6805 fetching of the pointer
6806 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6807 copied from genNearPointerSet()
6808 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6809 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6810 If they pop r0/r1 they must be called in the opposite order than aopOp().
6811 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6812 (resp. --stack-auto), prepared for --xstack

6823 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6825 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6826 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6827 type for bits was changed. It resulted in bit variables becoming
6828 global, which is not permitted in PIC 14 assembly output.
6830 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6832 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6845 A few small changes that speed up the peephole optimizer.
6849 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6851 Try to make the peephole optimizer smarter by maintaining
6852 an association between the assembly source code and the
6853 iCodes that originated them. Put this information to use
6854 with a new peephole rule condition "notVolatile" so that
6855 the rules can be aggressive yet still safe.
6860 * src/mcs51/peeph.def
6862 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6866 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6867 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6868 if the left or right operand symbols have the accuse flag set.
6870 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6872 Changed the type of the result of the ! (NOT) operator to char;
6873 previously it returned the same type as the source. This allows
6874 us to eliminate all the genFloatNot functions (all of its target
6875 implementations were very buggy) since !float can use the same
6878 * src/SDCCicode.c (ast2iCode): ! returns char

6880 * src/ds390/gen.c (genNot, genNotFloat),
6881 * src/z80/gen.c (genNot, genNotFloat),
6882 * src/pic/gen.c (genNot, genNotFloat),
6883 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6885 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6887 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6888 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6889 during interrupts. Ensure WSAVE is located at a shared bank address.
6890 2. Fixed page selection in some places
6891 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6892 the registers name strings.
6893 4. Fixed "signed / unsigned compare" compiler warnings.
6894 5. The PIC port manages its own allocation of the general purpose
6895 registers, but makes no attempt to reuse them. As a result when
6896 compiling it soon runs out of general purpose registers. Some
6897 additional code was added to the files pcode.c and device.c to walk
6898 through the function call tree and rename the registers so that they
6908 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6909 genPlus() & genMinus() when the result is the same as left or right

6915 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6917 Made bitfield a distinct type from bit so that bitfields
6918 convert as per ANSI C and bits retain their traditional
6919 boolean style behaviour. Implemented bitfield support in
6927 * src/ds390/gen.c: bit v bitfield split
6928 * src/z80/gen.c: New support for bitfields
6929 * support/regression/tests/bitfields.c: reenabled z80,
6932 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6934 Rules 246.x, 247.x relate to bitfields, the others speed up
6935 access to xdata mapped I/O devices.
6937 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6939 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6941 Cleaned up genPackBits and genUnpackBits and added two helper
6942 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6943 for literal assignments in genPackBits (thanks to Frieder for
6949 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6951 Fixed bug #748310 (pointer to function type mishandled when the
6952 function name is omitted). Also fixed a SIGSEGV when a function
6953 attribute (reentrant, etc) is used on a non-function or on a
6954 function but misplaced before the parameter list.
6956 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6958 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6981 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6983 Made the constant following the "interrupt" keyword optional. If
6984 omitted, the function will not automatically be given an entry
6985 in the interrupt vector table (similar to #pragma NOIV, but
6986 less syntacticly kludgy). The interrupt number is also now
6987 range checked. Also fixed a bug in the high order bit example

7003 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7005 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7006 be re-activated by defining REDUCE_LITERALS)
7007 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7008 unsigned, but are signed by default
7009 * src/SDCCval.c (constVal): rearranged
7010 * src/SDCCval.c (valMod): preliminary fix
7011 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7463 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7464 the regression tests I'm not brave enough to enable 245.b, 245.c
7465 * doc/sdccman.lyx: added latex preamble for hyperref package.
7466 Using pdflatex this will give you a hyperlinked pdf file with
7467 bookmarks. (prepend '%' before /usepackage if this breaks something)

7505 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7507 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7508 it can be defined with CFLAGS when running configure
7509 * src/SDCCmain.c: fixed compiling + linking with object files
7511 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7514 added --disable-pic16-port
7515 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7516 * src/SDCCmain.c: linkOptions is changed to set *,
7517 added if/endif conditional macros to remove options help
7518 messages from optionsTable when a port is not configured, added
7519 support for the PIc16 port in the ports table, when executing
7520 the compiler with no port specified on command line, a default
7521 port is selected with the new macro DEFAULT_PORT which is
7522 defined in port.h, in setDefaultOptions() linkOptions is removed
7523 from initialization assignment, since now it is a set,
7524 parseCmdLine uses setParseWithComma for linkOptions, in
7525 linkEdit() linkOptions are accessed with new function indexSet()
7526 which returns the i'th item of a set variable. See SDCCset.c, in
7527 linkEdit() when calling buildCmdLine(), added linkOptions as
7528 last argument. Now users can pass arguments to gplink via the
7529 -Wl option, main() uses pic16glue() to glue up pic16 programs

7541 * src/pic16/glue.c: commented out some error producing lines
7542 * src/pic16/main.c: __config directives are commented out to stop
7543 gpasm complaining and test the linkage with gplink, _linkCmd and
7544 _asmCmd changed to be more gplink and gpasm friendly
7545 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7546 produced an error when parsed, peep rule 12 is added to utilize
7547 movff, but it is commented out since the pCode does not support
7548 yet a command with 2 address arguments
7550 2003-05-18 <johan AT balder>
7552 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7579 2003-05-11 Borut Razem <borut.razem AT siol.net>
7581 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7582 the path of bin directory, so that PATH is the only env. variable, which has to be set
7583 in case of standard installation.
7584 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8677 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8679 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8680 overlaying area for it (uses RegBankUsed[4]).
8682 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8683 bank zero as used by default. By default aslink locates the stack
8684 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8685 the creation of the .mem file. Delegates the allocation of data area
8686 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8687 the begining of the stack area to aslink.
8689 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8690 glue() in SDCCglue.c creates an area for it.
8692 2002-09-03 Borut Razem <borut.razem AT siol.net>
8693 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8694 sdcc/src/pic/glue.c:
8695 introduced atexit() handler for teporay files removal in case of
8696 errors, assertions, ...
8698 2002-08-29 Borut Razem <borut.razem AT siol.net>
8699 * sdcc/support/cpp2/auto-host_vc_in.h:
8700 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8701 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8702 Maybe there is a similar problem with BORLANDC? It should be checked!
8704 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8705 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8706 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8707 was not executed, and the compiler (cl) launched a warning:
8708 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8710 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8711 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8713 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8714 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8716 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8717 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8718 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8719 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8720 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8721 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8722 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8723 - added Release configuration in VS projects
8724 - review of compiler an linker options
8725 - VC .exe files are generated in bin_vc directory, not to interfere
8726 with binaries generated from other projects (cygwin, mingw, bcc ...)
8728 * sdcc/src/yacc.dsp: added
8730 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8731 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8732 and insert the version number definitions from .version
8734 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8736 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8737 added - genarate auto-host.h using auto-host_vc_in.h as template
8740 removed from CVS, generated automatically
8742 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8743 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8745 2002-08-11 Borut Razem <borut.razem AT siol.net>
8746 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8748 2002-08-10 Borut Razem <borut.razem AT siol.net>
8749 * src/SDCCmain.c (main):
8750 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8751 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8752 The consequence was that some temporary files were not removed.
8755 unification of code in functions tempfilename() and tempfile():
8756 function tempnam() is defined in Visual Studio 6.0 and .NET
8758 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8760 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8761 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8762 - removed compiler command line option /WX: Treats all warnings as errors
8763 - update a list of source files, included into the project
8765 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8766 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8767 changed project type to Generic Project so that can be correcly converted to VS.NET project
8769 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8771 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8773 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8775 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8776 added return 0 statements after assert() to make compiler happy
8778 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8779 added newline in the def file to keep MSC compiler satisfied
8781 * sdcc/src/z80/gen.c:
8782 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8783 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8784 - solved MSC error in function aopDump()
8786 * sdcc_vc.h: define PREFIX as "\\sdcc"
8788 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8789 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8837 Added -p option. Allows port dependent processor to be specified.
8840 Initialized the new field char *Processor field to NULL in all ports
8843 Compiler generated registers for interrupt context saving
8844 were not getting allocated.
8846 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8849 Fixed left shift. Will promote the left side of a left shift
8850 if a) left shifting more than size of operand or b) when assigned
8851 to something size > size of left side
8853 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8961 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8963 * sdcc/src/SDCCloop.c:
8964 Previous fix was not good. basic blocks that have "break" or "return" are
8965 not really partof a loop , but live ranges used in these blocks should
8966 be live thru the entire loop, so set partOfLoop but don't add them to
8969 2002-02-21 <johan AT FRIJA>
8971 * src/SDCCcse.c: fixed bug #514308
8973 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8979 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8981 2002-02-10 Karl Bongers <karl AT turbobit.com>
