1466 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1467 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1468 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1469 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1470 always available in leading double underscore form. The C99 support is
1471 mostly missing, but it's a start.
1472 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1551 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1553 * device/lib/printf_large.c: removed inline assembly for portability and
1554 readability. Use printf_fast if speed or size are more important.
1555 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1556 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1558 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1560 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1561 prevent compiler warning
1563 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1565 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1566 moved to level 0 and declared as static. Also they are explicit
1567 placed in access bank. This was necessery because some times they
1568 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1569 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1570 optimizations. Currently only compare to unsigned char is implemented,
1571 * src/pic16/gen.c: added fReturnIdx array,
1572 * (struct resolvedIfx) is moved to gen.h and made public,
1573 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1574 * (aopForSym): added an optimization to directly store in stack of
1575 the operand of a SEND iCode,
1576 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1577 but as registers instead (AOP_REG) using the fReturnIdx array,
1578 * (pic16_freeAsmop): remove the freed register from the
1579 _G.sregsAlloc field,
1580 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1581 a compare of 'WREG',
1582 * (pic16_popGetTempRegCond): changed function prototype, now
1583 function takes also a bitVector argument v which holds the current
1584 set of registers that are allocated for stack access by aopForSym,
1585 registers allocated in aopForSym for accessing stack symbols are not
1586 any more part of the functions usedRegs field,
1587 * (genCall): some times aopOp is called for a stack variable to be
1588 send, aopForSym might perform the push, if this is true make sure
1589 that genCall doesn't push the variable twice by testing _G.resDirect,
1590 * (genFunction): changed testing for unspecified interrupt number
1591 from 256 to INTNO_UNSPEC,
1592 * modified selection scheme of frame pointer generation. Previously
1593 if function did use local registers a frame pointer was generated,
1594 now a frame pointer is generated only if function has arguments
1595 (that need PLUSW2 register access), or has stack arguments, or the
1596 compiler is not instructed to omit the frame pointer,
1597 * (genEndFunction): before restoring local registers that were saved
1598 in the function preamble, also restore the registers that *might*
1599 have been allocated for stack access,
1600 * (genRet): removed some old comments,
1601 * (genCmp, the active (RN's) version): added a call to the
1602 pic16_genCmp_special function to perform the compare with a more
1603 robust and optimized way,
1604 * (genInline): a feature has been added in inline code generation,
1605 which allows a wildcard variable substitution when writing inline
1606 assembly. Code is incomplete and experimental therefore undocumented,
1607 * (genCast): changed order of aopOp for result and right to allow
1608 aopForSym to directly load the result if possible,
1609 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1610 perform an optimized compare on some selected special occasions,
1611 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1612 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1613 generate an IVT any more,
1614 * src/pic16/main.c (pic16_optionsTable): added command line option
1616 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1617 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1619 * src/pic16/NOTES: Raphael Neider added in list of active developers
1620 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1621 jumptable_end to prevent bug #,
1622 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1623 inCond and outCond fields,
1624 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1625 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1626 turn off register spilling,
1627 * (packRegsForOneUse): synced with other ports' versions although it
1628 is not used currently,
1629 * (pic16_packRegisters): added an optimization while reading
1630 structure bitfields, some registers may be saved (malloc code is
1631 decreased by 80 bytes)
1633 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1635 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1636 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1637 this can be optimized more?
1639 2005-03-10 Raphael Neider <rneider AT web.de>
1641 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1642 genNearPointerGet): (hopefully) fixed access to bitfields via
1643 pointers (p->bitN = x; and x = p->bitN; failed)

1689 to keep the correct label reference count when adding/removing references
1690 to labels. A peephole file using this is appended to patch #1144962.

2277 Adding support for replacing ljmps with sjmps in jumptables
2278 generated for switch statements. For now you need to set the
2279 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2280 Now 4 algorithms for mcs51 jumptable generation are used:
2281 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2282 addresses loaded pc-relative for up to 112 cases and stack-pushing
2283 target addresses loaded with offset from dptr for up to 256 cases.

2313 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2315 * added libc directory. The current version of LibC contains string
2316 functions, ctype functions and macros and some functions of the
2317 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2318 be extensively tested in the future. Standard disclaimer here.
2319 Library is not automatically build yet. But one can build it by
2320 invoking 'make' inside the libc directory.
2321 * added ADC library under libio. Preliminary version yet.

2331 * (pic16_storeForReturn): optimized return of 0,
2332 * (genCmp): experimental code for new genCmp which uses PIC18's
2333 special compare&skip instructions. Initial tests fail some times
2334 with variables grater than 1 byte in size, so new code is disabled,
2335 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2337 * (genCast): began a fix to optimize the casting of a bit to another
2338 bit, now assigning a bitfield to another bitfield will fail, sorry,

2347 and 1 for banking instruction,
2348 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2349 caused stop processing pCodes after a inline assembly block,
2350 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2352 registers when it shouldn't,
2353 * src/pic16/ralloc.c (allocReg): add preliminary support for
2354 supporting a limited set of temporary registers,
2356 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2358 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2362 (genFunction): optimize RECEIVE iCodes in reentrant functions
2364 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2366 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5249 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5251 Fixed promotion, it should be done on AST level:
5252 * src/SDCCast.c (addCast): added promotion to int
5253 (decorateType): updated call to upCast()
5254 * src/SDCCicode.c (geniCodeLeftShift): removed call to
5255 usualUnaryConversions()
5257 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
5259 * support/regression/tests/literalop.c (mulWrapper): Added a
5260 wrapper to remove integer overflow warnings.

5264 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
5267 * support/regression/generate-cases.py (main): Changed from inline
5270 * doc/Makefile (install): Changed to depth first to get rid of
5271 missing directory install warning.
5273 * as/Makefile (install-doc): Made work on Mac.
5275 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5277 * src/SDCCast.c: added an additional type flow in decorateType() of
5278 opposite direction, see feature request #860006; it's enabled at runtime
5279 by setting the environment variable SDCC_NEWTYPEFLOW
5280 * src/SDCCast.h: changed prototype of decorateType()
5281 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5282 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5283 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5284 see feature request #877103
5285 * src/SDCCval.c: updated call of decorateType()
5286 (valBitwise): fixed bug #882876
5287 (valMinus): added promotion
5288 (valLogicAndOr): result is unsigned
5289 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5290 * src/SDCCsymt.c (computeType),
5291 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5292 must not cause an unsigned operation

5313 * src/pic/ralloc.h: applied patch from Slade Rich;
5314 added support for multiple code pages and multiple RAM banks on the
5315 PIC 14 port. The ASM files now no longer simply assume all the
5316 code / RAM are in the same page / bank. This means the linker can
5317 safely allocate code/RAM of separate ASM files to different pages/banks.
5318 * doc/sdccman.lyx: added Slade's tips
5319 * src/mcs51/peeph.def: fixed bug #880768

5331 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5332 strtof is not part of C89 and isn't included with Mac OS X.
5334 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5336 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5361 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5363 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5364 loaded with the linker search paths (-L arguments) and the libraries
5365 to be linked with the current source (-l arguments). Changes
5366 currently will affect only the pic16 port.
5367 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5368 include path the port specific paths and port specific libraries,
5369 * gplink command now contains the $3 argument,
5370 * src/pic16/device.h,
5371 * src/pic16/device.c,: structure PIC_device is made public and
5372 renamed to PIC16_device, the same for variable Pics which is renamed

5387 Documenting changes from previous commits.
5388 * configure.in (version 1.56),
5389 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5390 when generating output files to configure the pic16 library,
5391 but now I've commented it out, since gputils aren't installed in the
5392 SF compile farm, so library won't compile
5394 * device/lib/Makefile.in (version 1.56): initially I've added in
5395 target 'all' the prerequestive 'model-pic16' so it compiled the
5396 pic16 library, but now I've commented it out for the same reasons
5398 * added targets 'model-pic16' and 'objects-pic16' to compile the
5400 * added target 'port-specific-objects-pic16' to handle the
5401 generated libraries and copy them into the build/ directory
5402 * added target 'clean-intermediate-pic16' to clean intermediate
5403 files into pic16 directory
5404 * in target 'installdirs' added line to create directory pic16 in
5405 the installation path
5407 * device/include/Makefile.in (version 1.11): in target 'install'
5408 added lines to copy all header files to installation path,
5409 * in target 'installdirs' added line create directory for pic16
5410 headers in the installation path

5425 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5426 option so that it actually works. Made it specific to the z80, since
5427 the gbz80 doesn't have these kinds of I/O ports.
5429 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5431 * device/include/z180.h,

5453 Mainly changes to support compilation of the device libraries
5454 * src/pic16/device.c: stack is allocated via symbol and not
5455 via literal number. The symbol is placed in the corresponding
5456 position of the data ram
5457 * (pic16_dump_section): relocatable and absolute uninitialized
5458 data are now emitted in sorted order to reduce section naming,
5459 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5460 weren't marked as being in the access bank,
5462 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5464 Added portion of GNU PIC Library under the directory
5465 device/include/pic16 and device/lib/pic16. These files
5466 contain the declarations of SFRs for the PIC18Fxx2 devices.
5467 The directory is initialized via configure from toplevel.

5497 all over. Telling LaTeX to be less strict with word spacing
5498 to better keep the right margin. Changed some notes about
5499 maintainance of the ports in section 3.2.1 - is it OK like this?
5501 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5541 * src/pic16/peeph.def: all peepholes with movff are commented out,
5542 because there is a problem in the pcode peep optimizer,
5543 * src/pic16/ralloc.c: the register allocator can now reuse local

5682 Bug reported from Jesus Calvino-Fraga
5684 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5686 * sdcc.spec: updated
5687 * device/include/Makefile.in: don't install CVS directories
5688 * device/lib/Makefile.in: added removal of CVS directories after install
5689 * doc/Makefile: fixed install, added local_icons
5690 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

5695 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5697 PIC16 port related changes:
5698 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5699 added variable stackPos,
5701 * gen.c: genCall, assignResultValue: added support for
5702 pushing/retrieving function parameters to/from stack,
5703 genFunction,genEndFunction: setup stack frame for the
5705 genAddrOf: will be changed according to bug 863624
5707 * added files genutils.c and genutils.h which contain gen*
5708 debugged and optimised functions extracted from gen.c
5710 * glue.c: added variable 'externs' which holds extern symbols,
5711 pic16emitRegularMap: is modified to properly handle relocatable
5712 symbols under the new scheme,
5713 pic16createInterruptVect: is modified
5714 pic16printPublics: is modified to emit 'global' assembler directives,
5715 added pic16_printExterns to print extern symbols,
5716 pic16glue: initializes stack/frame pointer in the beginning of
5717 the assembly output. Temporary hack, will be corrected later,
5718 because gplink yet does not support stack and SDCC does not
5719 yet support a type of crt0.o object to create the final binary.
5721 * Removed many lines that contain 8051 legacy code.
5722 * The code is finally placed under a 'code' directive.
5723 * Added port specific options.
5725 * _process_pragma: simplified since now we do not need *special*
5726 include file to define SFR registers. But a separate header
5727 will be needed. This will be developed later.
5728 * _pic16_parseOptions: added, parses port specific options:
5729 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5730 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5731 --preplace-udata-with=
5733 * _pic16_setDefaultOptions: modified to initialize section names,
5734 but hack is temporarly out of order since it needs improvement.
5735 * _pic16_genAssemblerPreamble: configuration words are emitted by
5736 their address instead of their name. This part is incomplete and
5737 supports only the 18Fxx2 devices. Other devices will emit an error
5738 during assembly since they do not contain the same set of config
5740 * _pic16_genIVT: is modified,
5742 * pcode.c: added definitions for some hardware registers that are needed
5744 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5745 All PCI entries are updated. Now LFSR is supported.
5746 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5747 * added pic16_newpCodeOpLit2 to support instructions with
5748 two literal arguments
5749 * pic16_pCode2str: corrected code that emits assembler instructions
5750 with two literal operands and those that have an access bit modifier
5751 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5752 this fixes a bug which caused some labels to be lost, when an
5753 assembler directive was added, i.e. banksel,
5754 * pic16_FixRegisterBanking: improved logic that causes the insertion
5756 * InlineFunction: functions that are called once, are not any more
5757 inlined. This can be a port option in the future,
5759 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5761 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5762 hold the corresponding uninitialized symbols,
5763 * pic16_allocProcessorRegister: registers have explicit marked the
5765 * pic16_allocInternalRegister: registers are explicit marked as
5767 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5768 processing list, so bit registers were lost,
5771 * ralloc.h: added field 'accessBank' and original symbol operand
5772 in register definition,
5773 * removed the field isMapped from register definition,
5775 ** Several functions have been removed from various sources:
5776 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5777 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5778 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5779 pic16_assignRelocatableRegisters
5781 ** others have been introduced:
5782 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5783 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5785 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5787 * support/scripts/inc2h.pl: changed definition of BIT_AT
5788 to emit 'sbit at' instead of 'bit at'. This was a request.
5790 PIC16 port related preliminary changes:
5791 * gen.c: prefixed function popRegFromString with
5792 pic16_ and all references to it corrected
5793 * pcode.c: all pic16_pc_* hardware registers prefixed
5794 with underscore (_),
5795 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5796 * ralloc.c: newReg(): when register is REG_SFR then
5797 set address to rIdx,
5798 pic16_allocProcessorRegister(): marks register wasUsed=0
5799 pic16_writeUsedRegs(): added a call to assign processor
5800 registers via pic16_assignFixedRegisters
5802 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5804 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5805 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5806 variables in unused register banks. Also the SSEG is placed
5807 wherever there is enough space for it, and IDATA can be anywhere
5808 in internal RAM. For now compile using -Wl-Y[stack_size].
5809 The mem file is different for this option as well, since it
5810 makes no sense of talking about DSEG lenght.
5812 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5814 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5815 in certain cases, e.g. when ROM assignment, patch provided
5816 from Albert den Haan.

6059 * src/SDCCast.c (decorateType): disabled a transformation I added in
6060 revision 1.188 (access to fields of a structure at an absolute address);
6061 it breaks with bitfields, extern declarations, and gcse analysis.
6062 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6063 could be assigned through a pointer, so don't complain.

6171 xdata initialization slightly shorter
6173 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6823 copied from genNearPointerSet()
6824 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6825 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6841 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6842 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6843 type for bits was changed. It resulted in bit variables becoming

6861 A few small changes that speed up the peephole optimizer.
6865 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6867 Try to make the peephole optimizer smarter by maintaining
6868 an association between the assembly source code and the
6869 iCodes that originated them. Put this information to use
6870 with a new peephole rule condition "notVolatile" so that
6871 the rules can be aggressive yet still safe.
6876 * src/mcs51/peeph.def
6878 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6882 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6883 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6884 if the left or right operand symbols have the accuse flag set.
6886 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6888 Changed the type of the result of the ! (NOT) operator to char;
6889 previously it returned the same type as the source. This allows
6890 us to eliminate all the genFloatNot functions (all of its target
6891 implementations were very buggy) since !float can use the same
6894 * src/SDCCicode.c (ast2iCode): ! returns char

6903 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6904 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6905 during interrupts. Ensure WSAVE is located at a shared bank address.
6906 2. Fixed page selection in some places
6907 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6908 the registers name strings.
6909 4. Fixed "signed / unsigned compare" compiler warnings.
6910 5. The PIC port manages its own allocation of the general purpose
6911 registers, but makes no attempt to reuse them. As a result when
6912 compiling it soon runs out of general purpose registers. Some
6913 additional code was added to the files pcode.c and device.c to walk
6914 through the function call tree and rename the registers so that they
6924 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6925 genPlus() & genMinus() when the result is the same as left or right

6931 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6933 Made bitfield a distinct type from bit so that bitfields
6934 convert as per ANSI C and bits retain their traditional
6935 boolean style behaviour. Implemented bitfield support in
6943 * src/ds390/gen.c: bit v bitfield split
6944 * src/z80/gen.c: New support for bitfields
6945 * support/regression/tests/bitfields.c: reenabled z80,
6948 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6950 Rules 246.x, 247.x relate to bitfields, the others speed up
6951 access to xdata mapped I/O devices.
6953 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6955 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6957 Cleaned up genPackBits and genUnpackBits and added two helper
6958 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6959 for literal assignments in genPackBits (thanks to Frieder for
6965 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6967 Fixed bug #748310 (pointer to function type mishandled when the
6968 function name is omitted). Also fixed a SIGSEGV when a function
6969 attribute (reentrant, etc) is used on a non-function or on a
6970 function but misplaced before the parameter list.
6972 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6974 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6975 * support/Util/SDCCerr.h,
6976 * support/Util/SDCCerr.c: Added func attr misuse error msg

6997 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6999 Made the constant following the "interrupt" keyword optional. If
7000 omitted, the function will not automatically be given an entry
7001 in the interrupt vector table (similar to #pragma NOIV, but
7002 less syntacticly kludgy). The interrupt number is also now
7003 range checked. Also fixed a bug in the high order bit example
7010 * support/Util/SDCCerr.c
7011 * support/Util/SDCCerr.h
7014 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7017 * src/SDCCicode.c (operandOperation): rewritten some ops
7018 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7019 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7021 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7022 be re-activated by defining REDUCE_LITERALS)
7023 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7024 unsigned, but are signed by default
7025 * src/SDCCval.c (constVal): rearranged
7026 * src/SDCCval.c (valMod): preliminary fix
7027 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7069 constants are unsigned; added recognition of "u" flag for unsigned
7070 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7071 * src/SDCCval.c (valDiv, valMod): fixed signdness
7072 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7073 signedness of modulo, left and right shift

7479 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7480 the regression tests I'm not brave enough to enable 245.b, 245.c

7482 Using pdflatex this will give you a hyperlinked pdf file with
7483 bookmarks. (prepend '%' before /usepackage if this breaks something)

7530 added --disable-pic16-port
7531 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7532 * src/SDCCmain.c: linkOptions is changed to set *,
7533 added if/endif conditional macros to remove options help
7534 messages from optionsTable when a port is not configured, added
7535 support for the PIc16 port in the ports table, when executing
7536 the compiler with no port specified on command line, a default
7537 port is selected with the new macro DEFAULT_PORT which is
7538 defined in port.h, in setDefaultOptions() linkOptions is removed
7539 from initialization assignment, since now it is a set,
7540 parseCmdLine uses setParseWithComma for linkOptions, in
7541 linkEdit() linkOptions are accessed with new function indexSet()
7542 which returns the i'th item of a set variable. See SDCCset.c, in
7543 linkEdit() when calling buildCmdLine(), added linkOptions as
7544 last argument. Now users can pass arguments to gplink via the
7545 -Wl option, main() uses pic16glue() to glue up pic16 programs

7557 * src/pic16/glue.c: commented out some error producing lines
7558 * src/pic16/main.c: __config directives are commented out to stop
7559 gpasm complaining and test the linkage with gplink, _linkCmd and
7560 _asmCmd changed to be more gplink and gpasm friendly
7561 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7562 produced an error when parsed, peep rule 12 is added to utilize
7563 movff, but it is commented out since the pCode does not support
7564 yet a command with 2 address arguments
7566 2003-05-18 <johan AT balder>
7568 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7595 2003-05-11 Borut Razem <borut.razem AT siol.net>
7597 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7598 the path of bin directory, so that PATH is the only env. variable, which has to be set
7599 in case of standard installation.
7600 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8666 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8669 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8670 Changes to aslink (All the changes are marked with 'JCF'):
8672 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8675 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8676 area BSEG. Also moves, if possible, the DATA area down into the internal
8677 ram so more space is available.
8679 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8682 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8683 not bytes. Function summary() which creates a memory usage summary
8684 file with extension .mem. Reports of overlaping stack and small stack
8685 size. If the space for the stack is less than 16 bytes aslink trows a
8688 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8689 the 8051. Option 'y' for memory summary output file.
8691 Changes to sdcc (All the changes are marked with 'JCF'):
8693 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8695 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8696 overlaying area for it (uses RegBankUsed[4]).
8698 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8699 bank zero as used by default. By default aslink locates the stack
8700 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8701 the creation of the .mem file. Delegates the allocation of data area
8702 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8703 the begining of the stack area to aslink.
8705 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8706 glue() in SDCCglue.c creates an area for it.
8708 2002-09-03 Borut Razem <borut.razem AT siol.net>
8709 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8710 sdcc/src/pic/glue.c:
8711 introduced atexit() handler for teporay files removal in case of
8712 errors, assertions, ...
8714 2002-08-29 Borut Razem <borut.razem AT siol.net>
8715 * sdcc/support/cpp2/auto-host_vc_in.h:
8716 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8717 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8718 Maybe there is a similar problem with BORLANDC? It should be checked!
8720 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8721 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8722 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8723 was not executed, and the compiler (cl) launched a warning:
8724 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8726 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8727 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8729 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8730 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8732 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8733 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8734 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8735 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8736 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8737 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8738 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8739 - added Release configuration in VS projects
8740 - review of compiler an linker options
8741 - VC .exe files are generated in bin_vc directory, not to interfere
8742 with binaries generated from other projects (cygwin, mingw, bcc ...)
8744 * sdcc/src/yacc.dsp: added
8746 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8747 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8748 and insert the version number definitions from .version
8750 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8752 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8753 added - genarate auto-host.h using auto-host_vc_in.h as template
8756 removed from CVS, generated automatically
8758 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8759 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8761 2002-08-11 Borut Razem <borut.razem AT siol.net>
8762 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8764 2002-08-10 Borut Razem <borut.razem AT siol.net>
8765 * src/SDCCmain.c (main):
8766 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8767 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8768 The consequence was that some temporary files were not removed.
8771 unification of code in functions tempfilename() and tempfile():
8772 function tempnam() is defined in Visual Studio 6.0 and .NET
8774 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8776 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8777 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8778 - removed compiler command line option /WX: Treats all warnings as errors
8779 - update a list of source files, included into the project
8781 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8782 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8783 changed project type to Generic Project so that can be correcly converted to VS.NET project
8785 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8787 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8789 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8791 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8792 added return 0 statements after assert() to make compiler happy
8794 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8795 added newline in the def file to keep MSC compiler satisfied
8797 * sdcc/src/z80/gen.c:
8798 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8799 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8800 - solved MSC error in function aopDump()
8802 * sdcc_vc.h: define PREFIX as "\\sdcc"
8804 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8805 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8844 2002-03-28 Johan Knol <johan AT balder>
8846 * src/SDCCval.c: fixed bug #532436
8848 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8850 Added "char *Processor" field to the port structure.
8853 Added -p option. Allows port dependent processor to be specified.
8856 Initialized the new field char *Processor field to NULL in all ports
8859 Compiler generated registers for interrupt context saving
8860 were not getting allocated.
8862 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8865 Fixed left shift. Will promote the left side of a left shift
8866 if a) left shifting more than size of operand or b) when assigned
8867 to something size > size of left side
8869 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8871 tons of changes. Register allocation has been
8872 rewritten. Added customization for the various PICs. Flow

8977 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8979 * sdcc/src/SDCCloop.c:
8980 Previous fix was not good. basic blocks that have "break" or "return" are
8981 not really partof a loop , but live ranges used in these blocks should
8982 be live thru the entire loop, so set partOfLoop but don't add them to
8985 2002-02-21 <johan AT FRIJA>
8987 * src/SDCCcse.c: fixed bug #514308
8989 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8995 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8997 2002-02-10 Karl Bongers <karl AT turbobit.com>
9000 Fixed up SDCDB debugger somewhat. Updated debugger/README
9001 with lots of comments and notes.
