1462 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1463 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1464 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1465 always available in leading double underscore form. The C99 support is
1466 mostly missing, but it's a start.
1467 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1546 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1548 * device/lib/printf_large.c: removed inline assembly for portability and
1549 readability. Use printf_fast if speed or size are more important.
1550 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1551 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1553 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1555 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1556 prevent compiler warning
1558 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1560 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1561 moved to level 0 and declared as static. Also they are explicit
1562 placed in access bank. This was necessery because some times they
1563 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1564 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1565 optimizations. Currently only compare to unsigned char is implemented,
1566 * src/pic16/gen.c: added fReturnIdx array,
1567 * (struct resolvedIfx) is moved to gen.h and made public,
1568 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1569 * (aopForSym): added an optimization to directly store in stack of
1570 the operand of a SEND iCode,
1571 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1572 but as registers instead (AOP_REG) using the fReturnIdx array,
1573 * (pic16_freeAsmop): remove the freed register from the
1574 _G.sregsAlloc field,
1575 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1576 a compare of 'WREG',
1577 * (pic16_popGetTempRegCond): changed function prototype, now
1578 function takes also a bitVector argument v which holds the current
1579 set of registers that are allocated for stack access by aopForSym,
1580 registers allocated in aopForSym for accessing stack symbols are not
1581 any more part of the functions usedRegs field,
1582 * (genCall): some times aopOp is called for a stack variable to be
1583 send, aopForSym might perform the push, if this is true make sure
1584 that genCall doesn't push the variable twice by testing _G.resDirect,
1585 * (genFunction): changed testing for unspecified interrupt number
1586 from 256 to INTNO_UNSPEC,
1587 * modified selection scheme of frame pointer generation. Previously
1588 if function did use local registers a frame pointer was generated,
1589 now a frame pointer is generated only if function has arguments
1590 (that need PLUSW2 register access), or has stack arguments, or the
1591 compiler is not instructed to omit the frame pointer,
1592 * (genEndFunction): before restoring local registers that were saved
1593 in the function preamble, also restore the registers that *might*
1594 have been allocated for stack access,
1595 * (genRet): removed some old comments,
1596 * (genCmp, the active (RN's) version): added a call to the
1597 pic16_genCmp_special function to perform the compare with a more
1598 robust and optimized way,
1599 * (genInline): a feature has been added in inline code generation,
1600 which allows a wildcard variable substitution when writing inline
1601 assembly. Code is incomplete and experimental therefore undocumented,
1602 * (genCast): changed order of aopOp for result and right to allow
1603 aopForSym to directly load the result if possible,
1604 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1605 perform an optimized compare on some selected special occasions,
1606 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1607 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1608 generate an IVT any more,
1609 * src/pic16/main.c (pic16_optionsTable): added command line option
1611 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1612 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1614 * src/pic16/NOTES: Raphael Neider added in list of active developers
1615 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1616 jumptable_end to prevent bug #,
1617 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1618 inCond and outCond fields,
1619 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1620 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1621 turn off register spilling,
1622 * (packRegsForOneUse): synced with other ports' versions although it
1623 is not used currently,
1624 * (pic16_packRegisters): added an optimization while reading
1625 structure bitfields, some registers may be saved (malloc code is
1626 decreased by 80 bytes)
1628 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1630 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1631 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1632 this can be optimized more?
1634 2005-03-10 Raphael Neider <rneider AT web.de>
1636 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1637 genNearPointerGet): (hopefully) fixed access to bitfields via
1638 pointers (p->bitN = x; and x = p->bitN; failed)
1640 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1684 to keep the correct label reference count when adding/removing references
1685 to labels. A peephole file using this is appended to patch #1144962.

2272 Adding support for replacing ljmps with sjmps in jumptables
2273 generated for switch statements. For now you need to set the
2274 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2275 Now 4 algorithms for mcs51 jumptable generation are used:
2276 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2277 addresses loaded pc-relative for up to 112 cases and stack-pushing
2278 target addresses loaded with offset from dptr for up to 256 cases.

2308 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2310 * added libc directory. The current version of LibC contains string
2311 functions, ctype functions and macros and some functions of the
2312 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2313 be extensively tested in the future. Standard disclaimer here.
2314 Library is not automatically build yet. But one can build it by
2315 invoking 'make' inside the libc directory.
2316 * added ADC library under libio. Preliminary version yet.

2326 * (pic16_storeForReturn): optimized return of 0,
2327 * (genCmp): experimental code for new genCmp which uses PIC18's
2328 special compare&skip instructions. Initial tests fail some times
2329 with variables grater than 1 byte in size, so new code is disabled,
2330 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2332 * (genCast): began a fix to optimize the casting of a bit to another
2333 bit, now assigning a bitfield to another bitfield will fail, sorry,
2334 * src/pic16/main.c: disabled the use of lr-support feature,
2335 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2342 and 1 for banking instruction,
2343 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2344 caused stop processing pCodes after a inline assembly block,
2345 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2347 registers when it shouldn't,
2348 * src/pic16/ralloc.c (allocReg): add preliminary support for
2349 supporting a limited set of temporary registers,
2351 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2353 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2354 genDataPointerSet): ensure assignments always copy in MSB to LSB

2357 (genFunction): optimize RECEIVE iCodes in reentrant functions
2359 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5259 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
5262 * support/regression/generate-cases.py (main): Changed from inline
5265 * doc/Makefile (install): Changed to depth first to get rid of
5266 missing directory install warning.
5268 * as/Makefile (install-doc): Made work on Mac.
5270 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5272 * src/SDCCast.c: added an additional type flow in decorateType() of
5273 opposite direction, see feature request #860006; it's enabled at runtime
5274 by setting the environment variable SDCC_NEWTYPEFLOW
5275 * src/SDCCast.h: changed prototype of decorateType()
5276 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5277 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5278 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5279 see feature request #877103
5280 * src/SDCCval.c: updated call of decorateType()
5281 (valBitwise): fixed bug #882876
5282 (valMinus): added promotion
5283 (valLogicAndOr): result is unsigned
5284 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5285 * src/SDCCsymt.c (computeType),
5286 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5287 must not cause an unsigned operation
5288 * src/pic/glue (pic14emitRegularMap),
5289 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5291 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

5308 * src/pic/ralloc.h: applied patch from Slade Rich;
5309 added support for multiple code pages and multiple RAM banks on the
5310 PIC 14 port. The ASM files now no longer simply assume all the
5311 code / RAM are in the same page / bank. This means the linker can
5312 safely allocate code/RAM of separate ASM files to different pages/banks.
5313 * doc/sdccman.lyx: added Slade's tips
5314 * src/mcs51/peeph.def: fixed bug #880768

5326 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5327 strtof is not part of C89 and isn't included with Mac OS X.
5329 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5331 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5356 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5358 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5359 loaded with the linker search paths (-L arguments) and the libraries
5360 to be linked with the current source (-l arguments). Changes
5361 currently will affect only the pic16 port.
5362 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5363 include path the port specific paths and port specific libraries,
5364 * gplink command now contains the $3 argument,
5365 * src/pic16/device.h,
5366 * src/pic16/device.c,: structure PIC_device is made public and
5367 renamed to PIC16_device, the same for variable Pics which is renamed

5382 Documenting changes from previous commits.
5383 * configure.in (version 1.56),
5384 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5385 when generating output files to configure the pic16 library,
5386 but now I've commented it out, since gputils aren't installed in the
5387 SF compile farm, so library won't compile
5389 * device/lib/Makefile.in (version 1.56): initially I've added in
5390 target 'all' the prerequestive 'model-pic16' so it compiled the
5391 pic16 library, but now I've commented it out for the same reasons
5393 * added targets 'model-pic16' and 'objects-pic16' to compile the
5395 * added target 'port-specific-objects-pic16' to handle the
5396 generated libraries and copy them into the build/ directory
5397 * added target 'clean-intermediate-pic16' to clean intermediate
5398 files into pic16 directory
5399 * in target 'installdirs' added line to create directory pic16 in
5400 the installation path
5402 * device/include/Makefile.in (version 1.11): in target 'install'
5403 added lines to copy all header files to installation path,
5404 * in target 'installdirs' added line create directory for pic16
5405 headers in the installation path

5420 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5421 option so that it actually works. Made it specific to the z80, since
5422 the gbz80 doesn't have these kinds of I/O ports.
5424 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5426 * device/include/z180.h,

5448 Mainly changes to support compilation of the device libraries
5449 * src/pic16/device.c: stack is allocated via symbol and not
5450 via literal number. The symbol is placed in the corresponding
5451 position of the data ram
5452 * (pic16_dump_section): relocatable and absolute uninitialized
5453 data are now emitted in sorted order to reduce section naming,
5454 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5455 weren't marked as being in the access bank,
5457 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5459 Added portion of GNU PIC Library under the directory
5460 device/include/pic16 and device/lib/pic16. These files
5461 contain the declarations of SFRs for the PIC18Fxx2 devices.
5462 The directory is initialized via configure from toplevel.
5464 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5492 all over. Telling LaTeX to be less strict with word spacing
5493 to better keep the right margin. Changed some notes about
5494 maintainance of the ports in section 3.2.1 - is it OK like this?
5496 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5534 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5536 * src/pic16/peeph.def: all peepholes with movff are commented out,
5537 because there is a problem in the pcode peep optimizer,
5538 * src/pic16/ralloc.c: the register allocator can now reuse local

5677 Bug reported from Jesus Calvino-Fraga
5679 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5681 * sdcc.spec: updated
5682 * device/include/Makefile.in: don't install CVS directories

5685 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5686 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5687 * src/ds390/gen.c (genRightShift): fixed bug #870788
5688 * src/SDCCast.c (decorateType): fixed bug #870781
5690 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5692 PIC16 port related changes:
5693 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5694 added variable stackPos,
5696 * gen.c: genCall, assignResultValue: added support for
5697 pushing/retrieving function parameters to/from stack,
5698 genFunction,genEndFunction: setup stack frame for the
5700 genAddrOf: will be changed according to bug 863624
5702 * added files genutils.c and genutils.h which contain gen*
5703 debugged and optimised functions extracted from gen.c
5705 * glue.c: added variable 'externs' which holds extern symbols,
5706 pic16emitRegularMap: is modified to properly handle relocatable
5707 symbols under the new scheme,
5708 pic16createInterruptVect: is modified
5709 pic16printPublics: is modified to emit 'global' assembler directives,
5710 added pic16_printExterns to print extern symbols,
5711 pic16glue: initializes stack/frame pointer in the beginning of
5712 the assembly output. Temporary hack, will be corrected later,
5713 because gplink yet does not support stack and SDCC does not
5714 yet support a type of crt0.o object to create the final binary.
5716 * Removed many lines that contain 8051 legacy code.
5717 * The code is finally placed under a 'code' directive.
5718 * Added port specific options.
5720 * _process_pragma: simplified since now we do not need *special*
5721 include file to define SFR registers. But a separate header
5722 will be needed. This will be developed later.
5723 * _pic16_parseOptions: added, parses port specific options:
5724 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5725 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5726 --preplace-udata-with=
5728 * _pic16_setDefaultOptions: modified to initialize section names,
5729 but hack is temporarly out of order since it needs improvement.
5730 * _pic16_genAssemblerPreamble: configuration words are emitted by
5731 their address instead of their name. This part is incomplete and
5732 supports only the 18Fxx2 devices. Other devices will emit an error
5733 during assembly since they do not contain the same set of config
5735 * _pic16_genIVT: is modified,
5737 * pcode.c: added definitions for some hardware registers that are needed
5739 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5740 All PCI entries are updated. Now LFSR is supported.
5741 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5742 * added pic16_newpCodeOpLit2 to support instructions with
5743 two literal arguments
5744 * pic16_pCode2str: corrected code that emits assembler instructions
5745 with two literal operands and those that have an access bit modifier
5746 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5747 this fixes a bug which caused some labels to be lost, when an
5748 assembler directive was added, i.e. banksel,
5749 * pic16_FixRegisterBanking: improved logic that causes the insertion
5751 * InlineFunction: functions that are called once, are not any more
5752 inlined. This can be a port option in the future,
5754 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5756 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5757 hold the corresponding uninitialized symbols,
5758 * pic16_allocProcessorRegister: registers have explicit marked the
5760 * pic16_allocInternalRegister: registers are explicit marked as
5762 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5763 processing list, so bit registers were lost,
5766 * ralloc.h: added field 'accessBank' and original symbol operand
5767 in register definition,
5768 * removed the field isMapped from register definition,
5770 ** Several functions have been removed from various sources:
5771 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5772 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5773 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5774 pic16_assignRelocatableRegisters
5776 ** others have been introduced:
5777 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5778 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5780 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5782 * support/scripts/inc2h.pl: changed definition of BIT_AT
5783 to emit 'sbit at' instead of 'bit at'. This was a request.
5785 PIC16 port related preliminary changes:
5786 * gen.c: prefixed function popRegFromString with
5787 pic16_ and all references to it corrected
5788 * pcode.c: all pic16_pc_* hardware registers prefixed
5789 with underscore (_),
5790 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5791 * ralloc.c: newReg(): when register is REG_SFR then
5792 set address to rIdx,
5793 pic16_allocProcessorRegister(): marks register wasUsed=0
5794 pic16_writeUsedRegs(): added a call to assign processor
5795 registers via pic16_assignFixedRegisters
5797 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5799 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5800 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5801 variables in unused register banks. Also the SSEG is placed
5802 wherever there is enough space for it, and IDATA can be anywhere
5803 in internal RAM. For now compile using -Wl-Y[stack_size].
5804 The mem file is different for this option as well, since it
5805 makes no sense of talking about DSEG lenght.
5807 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5809 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6054 * src/SDCCast.c (decorateType): disabled a transformation I added in
6055 revision 1.188 (access to fields of a structure at an absolute address);
6056 it breaks with bitfields, extern declarations, and gcse analysis.
6057 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6058 could be assigned through a pointer, so don't complain.

6166 xdata initialization slightly shorter
6168 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6816 fetching of the pointer
6817 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6818 copied from genNearPointerSet()
6819 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6820 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6834 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6836 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6837 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6838 type for bits was changed. It resulted in bit variables becoming
6839 global, which is not permitted in PIC 14 assembly output.
6841 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6843 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6856 A few small changes that speed up the peephole optimizer.
6860 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6862 Try to make the peephole optimizer smarter by maintaining
6863 an association between the assembly source code and the
6864 iCodes that originated them. Put this information to use
6865 with a new peephole rule condition "notVolatile" so that
6866 the rules can be aggressive yet still safe.
6871 * src/mcs51/peeph.def
6873 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6877 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6878 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6879 if the left or right operand symbols have the accuse flag set.
6881 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6883 Changed the type of the result of the ! (NOT) operator to char;
6884 previously it returned the same type as the source. This allows
6885 us to eliminate all the genFloatNot functions (all of its target
6886 implementations were very buggy) since !float can use the same
6889 * src/SDCCicode.c (ast2iCode): ! returns char
6890 * src/mcs51/gen.c (genNot, genNotFloat),
6891 * src/ds390/gen.c (genNot, genNotFloat),
6892 * src/z80/gen.c (genNot, genNotFloat),
6893 * src/pic/gen.c (genNot, genNotFloat),
6894 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6896 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6898 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6899 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6900 during interrupts. Ensure WSAVE is located at a shared bank address.
6901 2. Fixed page selection in some places
6902 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6903 the registers name strings.
6904 4. Fixed "signed / unsigned compare" compiler warnings.
6905 5. The PIC port manages its own allocation of the general purpose
6906 registers, but makes no attempt to reuse them. As a result when
6907 compiling it soon runs out of general purpose registers. Some
6908 additional code was added to the files pcode.c and device.c to walk
6909 through the function call tree and rename the registers so that they
6919 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6920 genPlus() & genMinus() when the result is the same as left or right

6926 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6928 Made bitfield a distinct type from bit so that bitfields
6929 convert as per ANSI C and bits retain their traditional
6930 boolean style behaviour. Implemented bitfield support in
6938 * src/ds390/gen.c: bit v bitfield split
6939 * src/z80/gen.c: New support for bitfields
6940 * support/regression/tests/bitfields.c: reenabled z80,
6943 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6945 Rules 246.x, 247.x relate to bitfields, the others speed up
6946 access to xdata mapped I/O devices.
6948 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6950 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6952 Cleaned up genPackBits and genUnpackBits and added two helper
6953 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6954 for literal assignments in genPackBits (thanks to Frieder for
6960 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6962 Fixed bug #748310 (pointer to function type mishandled when the
6963 function name is omitted). Also fixed a SIGSEGV when a function
6964 attribute (reentrant, etc) is used on a non-function or on a
6965 function but misplaced before the parameter list.
6967 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6969 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6992 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6994 Made the constant following the "interrupt" keyword optional. If
6995 omitted, the function will not automatically be given an entry
6996 in the interrupt vector table (similar to #pragma NOIV, but
6997 less syntacticly kludgy). The interrupt number is also now
6998 range checked. Also fixed a bug in the high order bit example

7016 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7017 be re-activated by defining REDUCE_LITERALS)
7018 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7019 unsigned, but are signed by default
7020 * src/SDCCval.c (constVal): rearranged
7021 * src/SDCCval.c (valMod): preliminary fix
7022 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7474 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7475 the regression tests I'm not brave enough to enable 245.b, 245.c
7476 * doc/sdccman.lyx: added latex preamble for hyperref package.
7477 Using pdflatex this will give you a hyperlinked pdf file with
7478 bookmarks. (prepend '%' before /usepackage if this breaks something)

7516 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7518 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7519 it can be defined with CFLAGS when running configure
7520 * src/SDCCmain.c: fixed compiling + linking with object files
7522 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7525 added --disable-pic16-port
7526 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7527 * src/SDCCmain.c: linkOptions is changed to set *,
7528 added if/endif conditional macros to remove options help
7529 messages from optionsTable when a port is not configured, added
7530 support for the PIc16 port in the ports table, when executing
7531 the compiler with no port specified on command line, a default
7532 port is selected with the new macro DEFAULT_PORT which is
7533 defined in port.h, in setDefaultOptions() linkOptions is removed
7534 from initialization assignment, since now it is a set,
7535 parseCmdLine uses setParseWithComma for linkOptions, in
7536 linkEdit() linkOptions are accessed with new function indexSet()
7537 which returns the i'th item of a set variable. See SDCCset.c, in
7538 linkEdit() when calling buildCmdLine(), added linkOptions as
7539 last argument. Now users can pass arguments to gplink via the
7540 -Wl option, main() uses pic16glue() to glue up pic16 programs

7552 * src/pic16/glue.c: commented out some error producing lines
7553 * src/pic16/main.c: __config directives are commented out to stop
7554 gpasm complaining and test the linkage with gplink, _linkCmd and
7555 _asmCmd changed to be more gplink and gpasm friendly
7556 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7557 produced an error when parsed, peep rule 12 is added to utilize
7558 movff, but it is commented out since the pCode does not support
7559 yet a command with 2 address arguments
7561 2003-05-18 <johan AT balder>
7563 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7590 2003-05-11 Borut Razem <borut.razem AT siol.net>
7592 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7593 the path of bin directory, so that PATH is the only env. variable, which has to be set
7594 in case of standard installation.
7595 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8677 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8678 not bytes. Function summary() which creates a memory usage summary
8679 file with extension .mem. Reports of overlaping stack and small stack
8680 size. If the space for the stack is less than 16 bytes aslink trows a
8683 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8684 the 8051. Option 'y' for memory summary output file.
8686 Changes to sdcc (All the changes are marked with 'JCF'):
8688 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8690 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8691 overlaying area for it (uses RegBankUsed[4]).
8693 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8694 bank zero as used by default. By default aslink locates the stack
8695 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8696 the creation of the .mem file. Delegates the allocation of data area
8697 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8698 the begining of the stack area to aslink.
8700 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8701 glue() in SDCCglue.c creates an area for it.
8703 2002-09-03 Borut Razem <borut.razem AT siol.net>
8704 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8705 sdcc/src/pic/glue.c:
8706 introduced atexit() handler for teporay files removal in case of
8707 errors, assertions, ...
8709 2002-08-29 Borut Razem <borut.razem AT siol.net>
8710 * sdcc/support/cpp2/auto-host_vc_in.h:
8711 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8712 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8713 Maybe there is a similar problem with BORLANDC? It should be checked!
8715 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8716 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8717 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8718 was not executed, and the compiler (cl) launched a warning:
8719 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8721 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8722 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8724 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8725 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8727 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8728 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8729 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8730 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8731 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8732 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8733 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8734 - added Release configuration in VS projects
8735 - review of compiler an linker options
8736 - VC .exe files are generated in bin_vc directory, not to interfere
8737 with binaries generated from other projects (cygwin, mingw, bcc ...)
8739 * sdcc/src/yacc.dsp: added
8741 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8742 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8743 and insert the version number definitions from .version
8745 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8747 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8748 added - genarate auto-host.h using auto-host_vc_in.h as template
8751 removed from CVS, generated automatically
8753 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8754 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8756 2002-08-11 Borut Razem <borut.razem AT siol.net>
8757 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8759 2002-08-10 Borut Razem <borut.razem AT siol.net>
8760 * src/SDCCmain.c (main):
8761 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8762 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8763 The consequence was that some temporary files were not removed.
8766 unification of code in functions tempfilename() and tempfile():
8767 function tempnam() is defined in Visual Studio 6.0 and .NET
8769 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8771 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8772 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8773 - removed compiler command line option /WX: Treats all warnings as errors
8774 - update a list of source files, included into the project
8776 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8777 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8778 changed project type to Generic Project so that can be correcly converted to VS.NET project
8780 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8782 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8784 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8786 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8787 added return 0 statements after assert() to make compiler happy
8789 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8790 added newline in the def file to keep MSC compiler satisfied
8792 * sdcc/src/z80/gen.c:
8793 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8794 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8795 - solved MSC error in function aopDump()
8797 * sdcc_vc.h: define PREFIX as "\\sdcc"
8799 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8800 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8848 Added -p option. Allows port dependent processor to be specified.
8851 Initialized the new field char *Processor field to NULL in all ports
8854 Compiler generated registers for interrupt context saving
8855 were not getting allocated.
8857 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8860 Fixed left shift. Will promote the left side of a left shift
8861 if a) left shifting more than size of operand or b) when assigned
8862 to something size > size of left side
8864 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8972 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8974 * sdcc/src/SDCCloop.c:
8975 Previous fix was not good. basic blocks that have "break" or "return" are
8976 not really partof a loop , but live ranges used in these blocks should
8977 be live thru the entire loop, so set partOfLoop but don't add them to
8980 2002-02-21 <johan AT FRIJA>
8982 * src/SDCCcse.c: fixed bug #514308
8984 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8988 statement inside a loop, it was not being considered part of the loop.
8990 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8992 2002-02-10 Karl Bongers <karl AT turbobit.com>
8995 Fixed up SDCDB debugger somewhat. Updated debugger/README
8996 with lots of comments and notes.
8998 * device/examples/test2.c:
