471 2005-03-20 Borut Razem <borut.razem AT siol.net>
473 * support/scripts/inc2h.pl: WIN32 port

482 * device/lib/abs.c: added
483 * device/lib/labs.c: added
484 * device/include/stdlib.h: added abs() and labs() prototypes
485 * device/lib/libsdcc.lib: added abs and labs
486 * device/include/float.h,
487 * device/lib/_fsmul.c,
488 * device/lib/printf_fast.c,
489 * device/lib/printf_tiny.c: updated comments
491 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
493 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
496 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
498 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
499 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
501 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
503 * device/lib/printf_large.c: removed inline assembly for portability and
504 readability. Use printf_fast if speed or size are more important.
505 * src/pic16/gen.c: removed conditions around use of DEBUGpc
506 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
508 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
510 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
511 prevent compiler warning
513 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
515 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
516 moved to level 0 and declared as static. Also they are explicit
517 placed in access bank. This was necessery because some times they
518 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
519 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
520 optimizations. Currently only compare to unsigned char is implemented,
521 * src/pic16/gen.c: added fReturnIdx array,
522 * (struct resolvedIfx) is moved to gen.h and made public,
523 * (struct _G): added sregsAlloc and sregsAllocSet fields,
524 * (aopForSym): added an optimization to directly store in stack of
525 the operand of a SEND iCode,
526 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
527 but as registers instead (AOP_REG) using the fReturnIdx array,
528 * (pic16_freeAsmop): remove the freed register from the
530 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
532 * (pic16_popGetTempRegCond): changed function prototype, now
533 function takes also a bitVector argument v which holds the current
534 set of registers that are allocated for stack access by aopForSym,
535 registers allocated in aopForSym for accessing stack symbols are not
536 any more part of the functions usedRegs field,
537 * (genCall): some times aopOp is called for a stack variable to be
538 send, aopForSym might perform the push, if this is true make sure
539 that genCall doesn't push the variable twice by testing _G.resDirect,
540 * (genFunction): changed testing for unspecified interrupt number
541 from 256 to INTNO_UNSPEC,
542 * modified selection scheme of frame pointer generation. Previously
543 if function did use local registers a frame pointer was generated,
544 now a frame pointer is generated only if function has arguments
545 (that need PLUSW2 register access), or has stack arguments, or the
546 compiler is not instructed to omit the frame pointer,
547 * (genEndFunction): before restoring local registers that were saved
548 in the function preamble, also restore the registers that *might*
549 have been allocated for stack access,
550 * (genRet): removed some old comments,
551 * (genCmp, the active (RN's) version): added a call to the
552 pic16_genCmp_special function to perform the compare with a more
553 robust and optimized way,
554 * (genInline): a feature has been added in inline code generation,
555 which allows a wildcard variable substitution when writing inline
556 assembly. Code is incomplete and experimental therefore undocumented,
557 * (genCast): changed order of aopOp for result and right to allow
558 aopForSym to directly load the result if possible,
559 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
560 perform an optimized compare on some selected special occasions,
561 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
562 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
563 generate an IVT any more,
564 * src/pic16/main.c (pic16_optionsTable): added command line option
566 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
567 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
569 * src/pic16/NOTES: Raphael Neider added in list of active developers
570 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
571 jumptable_end to prevent bug #,
572 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
573 inCond and outCond fields,
574 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
575 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
576 turn off register spilling,
577 * (packRegsForOneUse): synced with other ports' versions although it
578 is not used currently,
579 * (pic16_packRegisters): added an optimization while reading
580 structure bitfields, some registers may be saved (malloc code is
581 decreased by 80 bytes)
583 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
585 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
586 left is a bitfield, if yes, then don't optimize assignment. Perhaps
587 this can be optimized more?
589 2005-03-10 Raphael Neider <rneider AT web.de>
591 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
592 genNearPointerGet): (hopefully) fixed access to bitfields via
593 pointers (p->bitN = x; and x = p->bitN; failed)

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

1228 generated for switch statements. For now you need to set the
1229 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1230 Now 4 algorithms for mcs51 jumptable generation are used:
1231 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1265 * added libc directory. The current version of LibC contains string
1266 functions, ctype functions and macros and some functions of the
1267 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1268 be extensively tested in the future. Standard disclaimer here.
1269 Library is not automatically build yet. But one can build it by

1281 * (pic16_storeForReturn): optimized return of 0,
1282 * (genCmp): experimental code for new genCmp which uses PIC18's
1283 special compare&skip instructions. Initial tests fail some times
1284 with variables grater than 1 byte in size, so new code is disabled,
1285 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1287 * (genCast): began a fix to optimize the casting of a bit to another
1288 bit, now assigning a bitfield to another bitfield will fail, sorry,

1302 registers when it shouldn't,
1303 * src/pic16/ralloc.c (allocReg): add preliminary support for
1304 supporting a limited set of temporary registers,
1306 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1312 (genFunction): optimize RECEIVE iCodes in reentrant functions
1314 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1330 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1332 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4311 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4313 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4314 loaded with the linker search paths (-L arguments) and the libraries
4315 to be linked with the current source (-l arguments). Changes
4316 currently will affect only the pic16 port.
4317 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4318 include path the port specific paths and port specific libraries,
4319 * gplink command now contains the $3 argument,
4320 * src/pic16/device.h,
4321 * src/pic16/device.c,: structure PIC_device is made public and
4322 renamed to PIC16_device, the same for variable Pics which is renamed

4337 Documenting changes from previous commits.
4338 * configure.in (version 1.56),
4339 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4340 when generating output files to configure the pic16 library,
4341 but now I've commented it out, since gputils aren't installed in the
4342 SF compile farm, so library won't compile
4344 * device/lib/Makefile.in (version 1.56): initially I've added in
4345 target 'all' the prerequestive 'model-pic16' so it compiled the
4346 pic16 library, but now I've commented it out for the same reasons
4348 * added targets 'model-pic16' and 'objects-pic16' to compile the
4350 * added target 'port-specific-objects-pic16' to handle the
4351 generated libraries and copy them into the build/ directory
4352 * added target 'clean-intermediate-pic16' to clean intermediate
4353 files into pic16 directory
4354 * in target 'installdirs' added line to create directory pic16 in
4355 the installation path

4358 added lines to copy all header files to installation path,
4359 * in target 'installdirs' added line create directory for pic16
4360 headers in the installation path

4375 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4376 option so that it actually works. Made it specific to the z80, since
4377 the gbz80 doesn't have these kinds of I/O ports.
4379 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4381 * device/include/z180.h,

4405 via literal number. The symbol is placed in the corresponding
4406 position of the data ram
4407 * (pic16_dump_section): relocatable and absolute uninitialized
4408 data are now emitted in sorted order to reduce section naming,
4409 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4410 weren't marked as being in the access bank,
4412 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4414 Added portion of GNU PIC Library under the directory
4415 device/include/pic16 and device/lib/pic16. These files
4416 contain the declarations of SFRs for the PIC18Fxx2 devices.
4417 The directory is initialized via configure from toplevel.
4419 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4447 all over. Telling LaTeX to be less strict with word spacing
4448 to better keep the right margin. Changed some notes about
4449 maintainance of the ports in section 3.2.1 - is it OK like this?
4451 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4488 UPPER for immediate operands,
4489 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4491 * src/pic16/peeph.def: all peepholes with movff are commented out,
4492 because there is a problem in the pcode peep optimizer,
4493 * src/pic16/ralloc.c: the register allocator can now reuse local

4605 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4606 (default behaviour).
4608 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4610 A python script to validate compiler diagnostic messages. It can be
4611 used to verify that sdcc complains about bad c source code and

4645 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4647 PIC16 port related changes:
4648 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4649 added variable stackPos,
4651 * gen.c: genCall, assignResultValue: added support for
4652 pushing/retrieving function parameters to/from stack,
4653 genFunction,genEndFunction: setup stack frame for the
4655 genAddrOf: will be changed according to bug 863624
4657 * added files genutils.c and genutils.h which contain gen*
4658 debugged and optimised functions extracted from gen.c
4660 * glue.c: added variable 'externs' which holds extern symbols,
4661 pic16emitRegularMap: is modified to properly handle relocatable
4662 symbols under the new scheme,
4663 pic16createInterruptVect: is modified
4664 pic16printPublics: is modified to emit 'global' assembler directives,
4665 added pic16_printExterns to print extern symbols,
4666 pic16glue: initializes stack/frame pointer in the beginning of
4667 the assembly output. Temporary hack, will be corrected later,
4668 because gplink yet does not support stack and SDCC does not
4669 yet support a type of crt0.o object to create the final binary.
4671 * Removed many lines that contain 8051 legacy code.
4672 * The code is finally placed under a 'code' directive.
4673 * Added port specific options.
4675 * _process_pragma: simplified since now we do not need *special*
4676 include file to define SFR registers. But a separate header
4677 will be needed. This will be developed later.
4678 * _pic16_parseOptions: added, parses port specific options:
4679 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4680 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4681 --preplace-udata-with=
4683 * _pic16_setDefaultOptions: modified to initialize section names,
4684 but hack is temporarly out of order since it needs improvement.
4685 * _pic16_genAssemblerPreamble: configuration words are emitted by
4686 their address instead of their name. This part is incomplete and
4687 supports only the 18Fxx2 devices. Other devices will emit an error
4688 during assembly since they do not contain the same set of config
4690 * _pic16_genIVT: is modified,
4692 * pcode.c: added definitions for some hardware registers that are needed
4694 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4695 All PCI entries are updated. Now LFSR is supported.
4696 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4697 * added pic16_newpCodeOpLit2 to support instructions with
4698 two literal arguments
4699 * pic16_pCode2str: corrected code that emits assembler instructions
4700 with two literal operands and those that have an access bit modifier
4701 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4702 this fixes a bug which caused some labels to be lost, when an
4703 assembler directive was added, i.e. banksel,
4704 * pic16_FixRegisterBanking: improved logic that causes the insertion
4706 * InlineFunction: functions that are called once, are not any more
4707 inlined. This can be a port option in the future,
4709 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4711 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4712 hold the corresponding uninitialized symbols,
4713 * pic16_allocProcessorRegister: registers have explicit marked the
4715 * pic16_allocInternalRegister: registers are explicit marked as
4717 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4718 processing list, so bit registers were lost,
4721 * ralloc.h: added field 'accessBank' and original symbol operand
4722 in register definition,
4723 * removed the field isMapped from register definition,
4725 ** Several functions have been removed from various sources:
4726 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4727 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4728 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4729 pic16_assignRelocatableRegisters
4731 ** others have been introduced:
4732 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4733 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4735 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4737 * support/scripts/inc2h.pl: changed definition of BIT_AT
4738 to emit 'sbit at' instead of 'bit at'. This was a request.
4740 PIC16 port related preliminary changes:
4741 * gen.c: prefixed function popRegFromString with
4742 pic16_ and all references to it corrected
4743 * pcode.c: all pic16_pc_* hardware registers prefixed
4744 with underscore (_),
4745 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4746 * ralloc.c: newReg(): when register is REG_SFR then
4747 set address to rIdx,
4748 pic16_allocProcessorRegister(): marks register wasUsed=0
4749 pic16_writeUsedRegs(): added a call to assign processor
4750 registers via pic16_assignFixedRegisters
4752 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4754 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4755 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4756 variables in unused register banks. Also the SSEG is placed
4757 wherever there is enough space for it, and IDATA can be anywhere
4758 in internal RAM. For now compile using -Wl-Y[stack_size].
4759 The mem file is different for this option as well, since it
4760 makes no sense of talking about DSEG lenght.
4762 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4764 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4765 in certain cases, e.g. when ROM assignment, patch provided
4766 from Albert den Haan.
4768 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4911 * src/mcs51/peephole.def,
4912 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4913 (allows non-interrupt and interrupt code to safely compete for a resource

5653 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5654 support for standard C idiom of memory mapped variables; for
5655 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5656 to xdata int at 0x1234 tempvar = 1.
5657 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5658 provided by Akiya ISHIDA

5674 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5676 Fixed bug #621531 (const & volatile confusion in the type chain).
5677 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
5678 refer to the const or volatile state of the pointer itself.

5743 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
5744 pcoderegs.h, ralloc.c, ralloc.h
5745 * main.c: added top header and GPL license notice

5769 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5770 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5771 fetching of the pointer
5772 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5773 copied from genNearPointerSet()
5774 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5775 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5776 If they pop r0/r1 they must be called in the opposite order than aopOp().
5777 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5778 (resp. --stack-auto), prepared for --xstack

5784 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5786 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5787 these ports have their own __sdcc_external_start()
5789 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5791 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5792 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5793 type for bits was changed. It resulted in bit variables becoming
5794 global, which is not permitted in PIC 14 assembly output.
5796 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5798 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5809 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5811 A few small changes that speed up the peephole optimizer.
5815 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5817 Try to make the peephole optimizer smarter by maintaining
5818 an association between the assembly source code and the
5819 iCodes that originated them. Put this information to use
5820 with a new peephole rule condition "notVolatile" so that
5821 the rules can be aggressive yet still safe.
5826 * src/mcs51/peeph.def
5828 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5832 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5833 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5834 if the left or right operand symbols have the accuse flag set.
5836 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5838 Changed the type of the result of the ! (NOT) operator to char;
5839 previously it returned the same type as the source. This allows
5840 us to eliminate all the genFloatNot functions (all of its target
5841 implementations were very buggy) since !float can use the same
5844 * src/SDCCicode.c (ast2iCode): ! returns char
5845 * src/mcs51/gen.c (genNot, genNotFloat),
5846 * src/ds390/gen.c (genNot, genNotFloat),
5847 * src/z80/gen.c (genNot, genNotFloat),
5848 * src/pic/gen.c (genNot, genNotFloat),
5849 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5851 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5853 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5854 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5855 during interrupts. Ensure WSAVE is located at a shared bank address.
5856 2. Fixed page selection in some places
5857 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5858 the registers name strings.
5859 4. Fixed "signed / unsigned compare" compiler warnings.
5860 5. The PIC port manages its own allocation of the general purpose
5861 registers, but makes no attempt to reuse them. As a result when
5862 compiling it soon runs out of general purpose registers. Some
5863 additional code was added to the files pcode.c and device.c to walk
5864 through the function call tree and rename the registers so that they
5874 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5875 genPlus() & genMinus() when the result is the same as left or right
5877 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5881 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5883 Made bitfield a distinct type from bit so that bitfields
5884 convert as per ANSI C and bits retain their traditional
5885 boolean style behaviour. Implemented bitfield support in
5893 * src/ds390/gen.c: bit v bitfield split
5894 * src/z80/gen.c: New support for bitfields
5895 * support/regression/tests/bitfields.c: reenabled z80,
5898 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5900 Rules 246.x, 247.x relate to bitfields, the others speed up
5901 access to xdata mapped I/O devices.
5903 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5905 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5907 Cleaned up genPackBits and genUnpackBits and added two helper
5908 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5909 for literal assignments in genPackBits (thanks to Frieder for
5915 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5917 Fixed bug #748310 (pointer to function type mishandled when the
5918 function name is omitted). Also fixed a SIGSEGV when a function
5919 attribute (reentrant, etc) is used on a non-function or on a
5920 function but misplaced before the parameter list.
5922 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5924 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5925 * support/Util/SDCCerr.h,
5926 * support/Util/SDCCerr.c: Added func attr misuse error msg
5928 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5930 Fixed bug #787649 by anonymous
5931 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5932 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5934 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5936 Fixed numerous bitfield problems.

5945 * support/regression/tests/bitfields.c: tests added
5947 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5949 Made the constant following the "interrupt" keyword optional. If
5950 omitted, the function will not automatically be given an entry
5951 in the interrupt vector table (similar to #pragma NOIV, but
5952 less syntacticly kludgy). The interrupt number is also now
5953 range checked. Also fixed a bug in the high order bit example
5960 * support/Util/SDCCerr.c
5961 * support/Util/SDCCerr.h
5964 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5966 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5967 * src/SDCCicode.c (operandOperation): rewritten some ops
5968 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5969 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5971 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5972 be re-activated by defining REDUCE_LITERALS)

6429 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6430 the regression tests I'm not brave enough to enable 245.b, 245.c
6431 * doc/sdccman.lyx: added latex preamble for hyperref package.
6432 Using pdflatex this will give you a hyperlinked pdf file with
6433 bookmarks. (prepend '%' before /usepackage if this breaks something)

6482 * src/SDCCmain.c: linkOptions is changed to set *,
6483 added if/endif conditional macros to remove options help
6484 messages from optionsTable when a port is not configured, added
6485 support for the PIc16 port in the ports table, when executing
6486 the compiler with no port specified on command line, a default
6487 port is selected with the new macro DEFAULT_PORT which is
6488 defined in port.h, in setDefaultOptions() linkOptions is removed
6489 from initialization assignment, since now it is a set,
6490 parseCmdLine uses setParseWithComma for linkOptions, in
6491 linkEdit() linkOptions are accessed with new function indexSet()
6492 which returns the i'th item of a set variable. See SDCCset.c, in
6493 linkEdit() when calling buildCmdLine(), added linkOptions as
6494 last argument. Now users can pass arguments to gplink via the
6495 -Wl option, main() uses pic16glue() to glue up pic16 programs

6508 * src/pic16/main.c: __config directives are commented out to stop
6509 gpasm complaining and test the linkage with gplink, _linkCmd and
6510 _asmCmd changed to be more gplink and gpasm friendly
6511 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6512 produced an error when parsed, peep rule 12 is added to utilize
6513 movff, but it is commented out since the pCode does not support
6514 yet a command with 2 address arguments
6516 2003-05-18 <johan AT balder>
6518 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7553 * src/SDCCicode.c: fixed array add
7555 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7556 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7557 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7559 2003-01-04 <johan AT balder>
7561 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7563 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7564 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7566 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7567 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7573 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7574 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7576 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7577 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7579 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7581 * in \sdcc\as\mcs51\ changed these files in order to create an
7582 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7583 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7584 following files to include the previous two files: aslink.dsp,
7585 Makefile.aslink, Makefile.bcc, and Makefile.in.
7587 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7588 .adb instead of .cdb
7590 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7592 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7593 value from option --iram-size.
7595 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7597 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7600 2002-09-18 <wiml AT hhhh.org>
7602 * SDCClrange.h: exposed setFromRange() and setToRange()
7603 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7604 packRegsForAccUse() (bug 542397)
7605 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7606 multiple times and emitting the fetch operations more than once
7607 added aopGetUsesAcc() function to allow binary operators to
7608 fetch their operands in the correct order; made genMinus() emit
7609 compact code for X = LITERAL - Y
7611 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7612 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7613 sprintf() in line 1267.
7615 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7616 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7619 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7620 Changes to aslink (All the changes are marked with 'JCF'):
7622 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7625 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7626 area BSEG. Also moves, if possible, the DATA area down into the internal
7627 ram so more space is available.
7629 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7632 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7633 not bytes. Function summary() which creates a memory usage summary
7634 file with extension .mem. Reports of overlaping stack and small stack
7635 size. If the space for the stack is less than 16 bytes aslink trows a
7638 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7639 the 8051. Option 'y' for memory summary output file.
7641 Changes to sdcc (All the changes are marked with 'JCF'):
7643 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7645 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7646 overlaying area for it (uses RegBankUsed[4]).
7648 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7649 bank zero as used by default. By default aslink locates the stack
7650 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7651 the creation of the .mem file. Delegates the allocation of data area
7652 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7653 the begining of the stack area to aslink.
7655 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7656 glue() in SDCCglue.c creates an area for it.
7658 2002-09-03 Borut Razem <borut.razem AT siol.net>
7659 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7660 sdcc/src/pic/glue.c:
7661 introduced atexit() handler for teporay files removal in case of
7662 errors, assertions, ...
7664 2002-08-29 Borut Razem <borut.razem AT siol.net>
7665 * sdcc/support/cpp2/auto-host_vc_in.h:
7666 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7667 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7668 Maybe there is a similar problem with BORLANDC? It should be checked!
7670 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7671 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7672 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7673 was not executed, and the compiler (cl) launched a warning:
7674 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7676 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7677 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7679 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7680 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7682 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7683 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7684 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7685 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7686 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7687 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7688 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7689 - added Release configuration in VS projects
7690 - review of compiler an linker options
7691 - VC .exe files are generated in bin_vc directory, not to interfere
7692 with binaries generated from other projects (cygwin, mingw, bcc ...)
7694 * sdcc/src/yacc.dsp: added
7696 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7697 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7698 and insert the version number definitions from .version
7700 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7702 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7703 added - genarate auto-host.h using auto-host_vc_in.h as template
7706 removed from CVS, generated automatically
7708 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7709 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7711 2002-08-11 Borut Razem <borut.razem AT siol.net>
7712 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7714 2002-08-10 Borut Razem <borut.razem AT siol.net>
7715 * src/SDCCmain.c (main):
7716 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7717 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7718 The consequence was that some temporary files were not removed.
7721 unification of code in functions tempfilename() and tempfile():
7722 function tempnam() is defined in Visual Studio 6.0 and .NET
7724 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7726 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7727 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7728 - removed compiler command line option /WX: Treats all warnings as errors
7729 - update a list of source files, included into the project
7731 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7732 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7733 changed project type to Generic Project so that can be correcly converted to VS.NET project
7735 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7737 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7739 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7741 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7742 added return 0 statements after assert() to make compiler happy
7744 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7745 added newline in the def file to keep MSC compiler satisfied
7747 * sdcc/src/z80/gen.c:
7748 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7749 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7750 - solved MSC error in function aopDump()
7752 * sdcc_vc.h: define PREFIX as "\\sdcc"
7754 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7755 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7758 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7759 - Rewrote the register banking algorithm.
7760 - Added pCode live-range analysis to registers (for now, only non-used and
7761 singly-used registers optimized away)
7763 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7765 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

7794 2002-03-28 Johan Knol <johan AT balder>
7796 * src/SDCCval.c: fixed bug #532436
7798 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7800 Added "char *Processor" field to the port structure.
7803 Added -p option. Allows port dependent processor to be specified.
7806 Initialized the new field char *Processor field to NULL in all ports
7809 Compiler generated registers for interrupt context saving
7810 were not getting allocated.
7812 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7815 Fixed left shift. Will promote the left side of a left shift
7816 if a) left shifting more than size of operand or b) when assigned
7817 to something size > size of left side
7819 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7821 tons of changes. Register allocation has been
7822 rewritten. Added customization for the various PICs. Flow
7823 analysis is restructured. ...
7829 Added. device.c is a PIC port hack to accomodate variations
7832 2002-03-13 Michael Hope <michaelh AT vroom>
7834 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7836 2002-03-04 johanknol <johanknol AT manik>
7838 * /src/SDCCval.c: fixed
7840 const unsigned char arr[][2] = { { 0, 1 } };

7843 2002-03-04 bela <bela AT manik>
7845 * /device/include/mcs51reg.h:
7846 ds89c420 register definition update
7848 2002-03-03 <johan AT FRIJA>
