664 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
666 * device/lib/printf_large.c: removed inline assembly for portability and
667 readability. Use printf_fast if speed or size are more important.
668 * src/pic16/gen.c: removed conditions around use of DEBUGpc
669 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
671 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
673 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
674 prevent compiler warning
676 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
678 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
679 moved to level 0 and declared as static. Also they are explicit
680 placed in access bank. This was necessery because some times they
681 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
682 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
683 optimizations. Currently only compare to unsigned char is implemented,
684 * src/pic16/gen.c: added fReturnIdx array,
685 * (struct resolvedIfx) is moved to gen.h and made public,
686 * (struct _G): added sregsAlloc and sregsAllocSet fields,
687 * (aopForSym): added an optimization to directly store in stack of
688 the operand of a SEND iCode,
689 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
690 but as registers instead (AOP_REG) using the fReturnIdx array,
691 * (pic16_freeAsmop): remove the freed register from the
693 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
695 * (pic16_popGetTempRegCond): changed function prototype, now
696 function takes also a bitVector argument v which holds the current
697 set of registers that are allocated for stack access by aopForSym,
698 registers allocated in aopForSym for accessing stack symbols are not
699 any more part of the functions usedRegs field,
700 * (genCall): some times aopOp is called for a stack variable to be
701 send, aopForSym might perform the push, if this is true make sure
702 that genCall doesn't push the variable twice by testing _G.resDirect,
703 * (genFunction): changed testing for unspecified interrupt number
704 from 256 to INTNO_UNSPEC,
705 * modified selection scheme of frame pointer generation. Previously
706 if function did use local registers a frame pointer was generated,
707 now a frame pointer is generated only if function has arguments
708 (that need PLUSW2 register access), or has stack arguments, or the
709 compiler is not instructed to omit the frame pointer,
710 * (genEndFunction): before restoring local registers that were saved
711 in the function preamble, also restore the registers that *might*
712 have been allocated for stack access,
713 * (genRet): removed some old comments,
714 * (genCmp, the active (RN's) version): added a call to the
715 pic16_genCmp_special function to perform the compare with a more
716 robust and optimized way,
717 * (genInline): a feature has been added in inline code generation,
718 which allows a wildcard variable substitution when writing inline
719 assembly. Code is incomplete and experimental therefore undocumented,
720 * (genCast): changed order of aopOp for result and right to allow
721 aopForSym to directly load the result if possible,
722 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
723 perform an optimized compare on some selected special occasions,
724 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
725 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
726 generate an IVT any more,
727 * src/pic16/main.c (pic16_optionsTable): added command line option
729 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
730 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
732 * src/pic16/NOTES: Raphael Neider added in list of active developers
733 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
734 jumptable_end to prevent bug #,
735 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
736 inCond and outCond fields,
737 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
738 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
739 turn off register spilling,
740 * (packRegsForOneUse): synced with other ports' versions although it
741 is not used currently,
742 * (pic16_packRegisters): added an optimization while reading
743 structure bitfields, some registers may be saved (malloc code is
744 decreased by 80 bytes)
746 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
748 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
749 left is a bitfield, if yes, then don't optimize assignment. Perhaps
750 this can be optimized more?
752 2005-03-10 Raphael Neider <rneider AT web.de>
754 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
755 genNearPointerGet): (hopefully) fixed access to bitfields via
756 pointers (p->bitN = x; and x = p->bitN; failed)
758 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
760 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1390 Adding support for replacing ljmps with sjmps in jumptables
1391 generated for switch statements. For now you need to set the
1392 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1393 Now 4 algorithms for mcs51 jumptable generation are used:
1394 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1395 addresses loaded pc-relative for up to 112 cases and stack-pushing
1396 target addresses loaded with offset from dptr for up to 256 cases.
1398 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1399 * src/mcs51/main.c: adapted constants for switch table generation

1423 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1424 to call when a stack overflow occurs,
1425 * (malloc.h): added CVS Id tag,
1426 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1428 * added libc directory. The current version of LibC contains string
1429 functions, ctype functions and macros and some functions of the
1430 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1431 be extensively tested in the future. Standard disclaimer here.
1432 Library is not automatically build yet. But one can build it by
1433 invoking 'make' inside the libc directory.
1434 * added ADC library under libio. Preliminary version yet.
1436 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1443 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1444 * (pic16_storeForReturn): optimized return of 0,
1445 * (genCmp): experimental code for new genCmp which uses PIC18's
1446 special compare&skip instructions. Initial tests fail some times
1447 with variables grater than 1 byte in size, so new code is disabled,
1448 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1450 * (genCast): began a fix to optimize the casting of a bit to another
1451 bit, now assigning a bitfield to another bitfield will fail, sorry,
1452 * src/pic16/main.c: disabled the use of lr-support feature,
1453 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1456 bits with offset (case PO_GPR_BIT),
1457 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1459 * (isBankInstruction): modified to return 0 for no banking instruction,
1460 and 1 for banking instruction,
1461 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1462 caused stop processing pCodes after a inline assembly block,
1463 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1464 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1465 registers when it shouldn't,
1466 * src/pic16/ralloc.c (allocReg): add preliminary support for
1467 supporting a limited set of temporary registers,
1469 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1471 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1472 genDataPointerSet): ensure assignments always copy in MSB to LSB
1474 (loadRegFromAop): recognize CLRH optimization,
1475 (genFunction): optimize RECEIVE iCodes in reentrant functions
1477 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1479 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4441 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4444 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4445 strtof is not part of C89 and isn't included with Mac OS X.
4447 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4474 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4476 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4477 loaded with the linker search paths (-L arguments) and the libraries
4478 to be linked with the current source (-l arguments). Changes
4479 currently will affect only the pic16 port.
4480 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4481 include path the port specific paths and port specific libraries,
4482 * gplink command now contains the $3 argument,
4483 * src/pic16/device.h,
4484 * src/pic16/device.c,: structure PIC_device is made public and
4485 renamed to PIC16_device, the same for variable Pics which is renamed
4486 to Pics16. Updated all references to them.
4487 * src/pic16/glue.c (pic16glue): corrected bug with code
4488 initialization which bypassed the variable initializations block.

4498 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4500 Documenting changes from previous commits.
4501 * configure.in (version 1.56),
4502 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4503 when generating output files to configure the pic16 library,
4504 but now I've commented it out, since gputils aren't installed in the
4505 SF compile farm, so library won't compile
4507 * device/lib/Makefile.in (version 1.56): initially I've added in
4508 target 'all' the prerequestive 'model-pic16' so it compiled the
4509 pic16 library, but now I've commented it out for the same reasons
4511 * added targets 'model-pic16' and 'objects-pic16' to compile the
4513 * added target 'port-specific-objects-pic16' to handle the
4514 generated libraries and copy them into the build/ directory
4515 * added target 'clean-intermediate-pic16' to clean intermediate
4516 files into pic16 directory
4517 * in target 'installdirs' added line to create directory pic16 in
4518 the installation path
4520 * device/include/Makefile.in (version 1.11): in target 'install'
4521 added lines to copy all header files to installation path,
4522 * in target 'installdirs' added line create directory for pic16
4523 headers in the installation path

4538 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4539 option so that it actually works. Made it specific to the z80, since
4540 the gbz80 doesn't have these kinds of I/O ports.
4542 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4544 * device/include/z180.h,

4553 portmode; added deprecation warning for bank= and protmode= forms.
4554 Also, guard against buffer overflow.
4555 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4557 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4559 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4560 changed interrupt vector table generation to only emit declared vectors.
4561 * device/include/Makefile.in: added missing backslash
4562 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4564 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4566 Mainly changes to support compilation of the device libraries
4567 * src/pic16/device.c: stack is allocated via symbol and not
4568 via literal number. The symbol is placed in the corresponding
4569 position of the data ram
4570 * (pic16_dump_section): relocatable and absolute uninitialized
4571 data are now emitted in sorted order to reduce section naming,
4572 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4573 weren't marked as being in the access bank,
4575 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4577 Added portion of GNU PIC Library under the directory
4578 device/include/pic16 and device/lib/pic16. These files
4579 contain the declarations of SFRs for the PIC18Fxx2 devices.
4580 The directory is initialized via configure from toplevel.
4582 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4584 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4585 the spilllocations to be compared correctly
4587 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4589 * src/SDCCast.c (decorateType): fixed bug introduced today
4591 2004-01-12 Borut Razem <borut.razem AT siol.net>
4593 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4596 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4598 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4599 in simpler and even better code
4601 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4603 * src/SDCCicode.c (operandOperation): fixed bug #874819

4607 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4609 * doc/sdccman.lyx: Moved and added some sections, small changes
4610 all over. Telling LaTeX to be less strict with word spacing
4611 to better keep the right margin. Changed some notes about
4612 maintainance of the ports in section 3.2.1 - is it OK like this?
4614 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4616 SDCC source changes:
4617 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4650 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4651 UPPER for immediate operands,
4652 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4654 * src/pic16/peeph.def: all peepholes with movff are commented out,
4655 because there is a problem in the pcode peep optimizer,
4656 * src/pic16/ralloc.c: the register allocator can now reuse local
4657 function symbols for another function. This saves register usage.
4658 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4660 Added file src/pic16/NOTES with information about program writing on
4661 the current port version.

4670 * src/SDCCmain.c : fixed #872250: -l command line defined library
4671 files are scanned before standard library files
4673 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4693 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4696 * src/z80/main.c: added missed needLinkerScript flags (more than
4697 one port structure defined in these file)
4698 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4714 needLinkerScript flag
4716 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4717 * src/pic/glue.c: added variable udata_section_name to
4718 override default uninitialized data segment definition for
4719 devices only with SHAREBANK memory (reported from Erik Epetrich)
4720 * (pic14emitOverlay): modified to emit a commented overlay segment
4721 directive when no overlay data exist
4722 * (picglue): modified to emit uninitialized data segment
4723 according to udata_section_name

4728 arguments via -W option
4729 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4730 object file from '.rel' to '.o' in port->linker structure,
4731 changed size of fptr from 2 to 3 in port structure
4733 2004-01-07 Borut Razem <borut.razem AT siol.net>
4735 * support/scripts/sdcc.nsi: update PATH
4736 * support/scripts/sdcc.ico: craeted
4738 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4740 * device/include/Makefile.in: fix install
4741 * doc/Makefile: fix install
4743 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4745 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4747 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4749 include information about variables allocated to the overlay
4752 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4754 * as/mcs51/lkmain.c: Help about -Y option

4766 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4768 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4769 (default behaviour).
4771 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4773 A python script to validate compiler diagnostic messages. It can be
4774 used to verify that sdcc complains about bad c source code and
4775 gives a good location of the error.
4776 * support/valdiag/Makefile,
4777 * support/valdiag/valdiag.py,
4778 * support/valdiag/tests/*
4780 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4782 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4783 * src/SDCCsymt.c (newEnumType),

4791 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4793 * src/common.h: added ifndef/define/endif macros
4794 around the header file.
4795 Bug reported from Jesus Calvino-Fraga
4797 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4799 * sdcc.spec: updated
4800 * device/include/Makefile.in: don't install CVS directories
4801 * device/lib/Makefile.in: added removal of CVS directories after install
4802 * doc/Makefile: fixed install, added local_icons
4803 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4804 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4805 * src/ds390/gen.c (genRightShift): fixed bug #870788
4806 * src/SDCCast.c (decorateType): fixed bug #870781
4808 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4810 PIC16 port related changes:
4811 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4812 added variable stackPos,
4814 * gen.c: genCall, assignResultValue: added support for
4815 pushing/retrieving function parameters to/from stack,
4816 genFunction,genEndFunction: setup stack frame for the
4818 genAddrOf: will be changed according to bug 863624
4820 * added files genutils.c and genutils.h which contain gen*
4821 debugged and optimised functions extracted from gen.c
4823 * glue.c: added variable 'externs' which holds extern symbols,
4824 pic16emitRegularMap: is modified to properly handle relocatable
4825 symbols under the new scheme,
4826 pic16createInterruptVect: is modified
4827 pic16printPublics: is modified to emit 'global' assembler directives,
4828 added pic16_printExterns to print extern symbols,
4829 pic16glue: initializes stack/frame pointer in the beginning of
4830 the assembly output. Temporary hack, will be corrected later,
4831 because gplink yet does not support stack and SDCC does not
4832 yet support a type of crt0.o object to create the final binary.
4834 * Removed many lines that contain 8051 legacy code.
4835 * The code is finally placed under a 'code' directive.
4836 * Added port specific options.
4838 * _process_pragma: simplified since now we do not need *special*
4839 include file to define SFR registers. But a separate header
4840 will be needed. This will be developed later.
4841 * _pic16_parseOptions: added, parses port specific options:
4842 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4843 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4844 --preplace-udata-with=
4846 * _pic16_setDefaultOptions: modified to initialize section names,
4847 but hack is temporarly out of order since it needs improvement.
4848 * _pic16_genAssemblerPreamble: configuration words are emitted by
4849 their address instead of their name. This part is incomplete and
4850 supports only the 18Fxx2 devices. Other devices will emit an error
4851 during assembly since they do not contain the same set of config
4853 * _pic16_genIVT: is modified,
4855 * pcode.c: added definitions for some hardware registers that are needed
4857 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4858 All PCI entries are updated. Now LFSR is supported.
4859 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4860 * added pic16_newpCodeOpLit2 to support instructions with
4861 two literal arguments
4862 * pic16_pCode2str: corrected code that emits assembler instructions
4863 with two literal operands and those that have an access bit modifier
4864 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4865 this fixes a bug which caused some labels to be lost, when an
4866 assembler directive was added, i.e. banksel,
4867 * pic16_FixRegisterBanking: improved logic that causes the insertion
4869 * InlineFunction: functions that are called once, are not any more
4870 inlined. This can be a port option in the future,
4872 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4874 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4875 hold the corresponding uninitialized symbols,
4876 * pic16_allocProcessorRegister: registers have explicit marked the
4878 * pic16_allocInternalRegister: registers are explicit marked as
4880 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4881 processing list, so bit registers were lost,
4884 * ralloc.h: added field 'accessBank' and original symbol operand
4885 in register definition,
4886 * removed the field isMapped from register definition,
4888 ** Several functions have been removed from various sources:
4889 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4890 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4891 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4892 pic16_assignRelocatableRegisters
4894 ** others have been introduced:
4895 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4896 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4898 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4900 * support/scripts/inc2h.pl: changed definition of BIT_AT
4901 to emit 'sbit at' instead of 'bit at'. This was a request.
4903 PIC16 port related preliminary changes:
4904 * gen.c: prefixed function popRegFromString with
4905 pic16_ and all references to it corrected
4906 * pcode.c: all pic16_pc_* hardware registers prefixed
4907 with underscore (_),
4908 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4909 * ralloc.c: newReg(): when register is REG_SFR then
4910 set address to rIdx,
4911 pic16_allocProcessorRegister(): marks register wasUsed=0
4912 pic16_writeUsedRegs(): added a call to assign processor
4913 registers via pic16_assignFixedRegisters
4915 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4917 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4918 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4919 variables in unused register banks. Also the SSEG is placed
4920 wherever there is enough space for it, and IDATA can be anywhere
4921 in internal RAM. For now compile using -Wl-Y[stack_size].
4922 The mem file is different for this option as well, since it
4923 makes no sense of talking about DSEG lenght.
4925 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4927 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5927 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5928 before instructions that use the _STATUS register
5930 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5932 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5933 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5934 fetching of the pointer
5935 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5936 copied from genNearPointerSet()
5937 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5938 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5939 If they pop r0/r1 they must be called in the opposite order than aopOp().
5940 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5941 (resp. --stack-auto), prepared for --xstack

5950 these ports have their own __sdcc_external_start()
5952 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5954 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5955 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5956 type for bits was changed. It resulted in bit variables becoming
5957 global, which is not permitted in PIC 14 assembly output.
5959 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5961 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5963 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5965 Z80 and MCS51 linkers complaint if a public symbol is defined

5974 A few small changes that speed up the peephole optimizer.
5978 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5980 Try to make the peephole optimizer smarter by maintaining
5981 an association between the assembly source code and the
5982 iCodes that originated them. Put this information to use
5983 with a new peephole rule condition "notVolatile" so that
5984 the rules can be aggressive yet still safe.
5989 * src/mcs51/peeph.def
5991 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5995 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5996 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5997 if the left or right operand symbols have the accuse flag set.
5999 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6001 Changed the type of the result of the ! (NOT) operator to char;
6002 previously it returned the same type as the source. This allows
6003 us to eliminate all the genFloatNot functions (all of its target
6004 implementations were very buggy) since !float can use the same
6007 * src/SDCCicode.c (ast2iCode): ! returns char

6009 * src/ds390/gen.c (genNot, genNotFloat),
6010 * src/z80/gen.c (genNot, genNotFloat),
6011 * src/pic/gen.c (genNot, genNotFloat),

6016 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6017 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6018 during interrupts. Ensure WSAVE is located at a shared bank address.
6019 2. Fixed page selection in some places
6020 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6021 the registers name strings.
6022 4. Fixed "signed / unsigned compare" compiler warnings.
6023 5. The PIC port manages its own allocation of the general purpose
6024 registers, but makes no attempt to reuse them. As a result when
6025 compiling it soon runs out of general purpose registers. Some
6026 additional code was added to the files pcode.c and device.c to walk
6027 through the function call tree and rename the registers so that they
6037 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6038 genPlus() & genMinus() when the result is the same as left or right

6044 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6046 Made bitfield a distinct type from bit so that bitfields
6047 convert as per ANSI C and bits retain their traditional
6048 boolean style behaviour. Implemented bitfield support in
6056 * src/ds390/gen.c: bit v bitfield split
6057 * src/z80/gen.c: New support for bitfields
6058 * support/regression/tests/bitfields.c: reenabled z80,
6061 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6063 Rules 246.x, 247.x relate to bitfields, the others speed up
6064 access to xdata mapped I/O devices.
6066 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6070 Cleaned up genPackBits and genUnpackBits and added two helper
6071 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6072 for literal assignments in genPackBits (thanks to Frieder for
6078 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6080 Fixed bug #748310 (pointer to function type mishandled when the
6081 function name is omitted). Also fixed a SIGSEGV when a function
6082 attribute (reentrant, etc) is used on a non-function or on a
6083 function but misplaced before the parameter list.
6085 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6087 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6110 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6112 Made the constant following the "interrupt" keyword optional. If
6113 omitted, the function will not automatically be given an entry
6114 in the interrupt vector table (similar to #pragma NOIV, but
6115 less syntacticly kludgy). The interrupt number is also now
6116 range checked. Also fixed a bug in the high order bit example

6130 * src/SDCCicode.c (operandOperation): rewritten some ops
6131 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6132 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6134 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6135 be re-activated by defining REDUCE_LITERALS)
6136 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6137 unsigned, but are signed by default
6138 * src/SDCCval.c (constVal): rearranged
6139 * src/SDCCval.c (valMod): preliminary fix
6140 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6595 Using pdflatex this will give you a hyperlinked pdf file with
6596 bookmarks. (prepend '%' before /usepackage if this breaks something)

6645 * src/SDCCmain.c: linkOptions is changed to set *,
6646 added if/endif conditional macros to remove options help
6647 messages from optionsTable when a port is not configured, added
6648 support for the PIc16 port in the ports table, when executing
6649 the compiler with no port specified on command line, a default
6650 port is selected with the new macro DEFAULT_PORT which is
6651 defined in port.h, in setDefaultOptions() linkOptions is removed
6652 from initialization assignment, since now it is a set,
6653 parseCmdLine uses setParseWithComma for linkOptions, in
6654 linkEdit() linkOptions are accessed with new function indexSet()
6655 which returns the i'th item of a set variable. See SDCCset.c, in
6656 linkEdit() when calling buildCmdLine(), added linkOptions as
6657 last argument. Now users can pass arguments to gplink via the
6658 -Wl option, main() uses pic16glue() to glue up pic16 programs

6670 * src/pic16/glue.c: commented out some error producing lines
6671 * src/pic16/main.c: __config directives are commented out to stop
6672 gpasm complaining and test the linkage with gplink, _linkCmd and
6673 _asmCmd changed to be more gplink and gpasm friendly
6674 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6675 produced an error when parsed, peep rule 12 is added to utilize
6676 movff, but it is commented out since the pCode does not support
6677 yet a command with 2 address arguments
6679 2003-05-18 <johan AT balder>
6681 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6708 2003-05-11 Borut Razem <borut.razem AT siol.net>
6710 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6711 the path of bin directory, so that PATH is the only env. variable, which has to be set
6712 in case of standard installation.

7742 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7744 * in \sdcc\as\mcs51\ changed these files in order to create an
7745 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7746 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7747 following files to include the previous two files: aslink.dsp,
7748 Makefile.aslink, Makefile.bcc, and Makefile.in.
7750 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7751 .adb instead of .cdb
7753 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7755 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7756 value from option --iram-size.
7758 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7760 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7763 2002-09-18 <wiml AT hhhh.org>
7765 * SDCClrange.h: exposed setFromRange() and setToRange()
7766 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7767 packRegsForAccUse() (bug 542397)
7768 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7769 multiple times and emitting the fetch operations more than once
7770 added aopGetUsesAcc() function to allow binary operators to
7771 fetch their operands in the correct order; made genMinus() emit
7772 compact code for X = LITERAL - Y
7774 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7775 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7776 sprintf() in line 1267.
7778 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7779 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7782 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7783 Changes to aslink (All the changes are marked with 'JCF'):
7785 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7788 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7789 area BSEG. Also moves, if possible, the DATA area down into the internal
7790 ram so more space is available.
7792 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7795 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7796 not bytes. Function summary() which creates a memory usage summary
7797 file with extension .mem. Reports of overlaping stack and small stack
7798 size. If the space for the stack is less than 16 bytes aslink trows a
7801 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7802 the 8051. Option 'y' for memory summary output file.
7804 Changes to sdcc (All the changes are marked with 'JCF'):
7806 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7808 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7809 overlaying area for it (uses RegBankUsed[4]).
7811 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7812 bank zero as used by default. By default aslink locates the stack
7813 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7814 the creation of the .mem file. Delegates the allocation of data area
7815 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7816 the begining of the stack area to aslink.
7818 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7819 glue() in SDCCglue.c creates an area for it.
7821 2002-09-03 Borut Razem <borut.razem AT siol.net>
7822 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7823 sdcc/src/pic/glue.c:
7824 introduced atexit() handler for teporay files removal in case of
7825 errors, assertions, ...
7827 2002-08-29 Borut Razem <borut.razem AT siol.net>
7828 * sdcc/support/cpp2/auto-host_vc_in.h:
7829 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7830 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7831 Maybe there is a similar problem with BORLANDC? It should be checked!
7833 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7834 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7835 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7836 was not executed, and the compiler (cl) launched a warning:
7837 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7839 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7840 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7842 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7845 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7846 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7847 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7848 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7849 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7850 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7851 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7852 - added Release configuration in VS projects
7853 - review of compiler an linker options
7854 - VC .exe files are generated in bin_vc directory, not to interfere
7855 with binaries generated from other projects (cygwin, mingw, bcc ...)
7857 * sdcc/src/yacc.dsp: added
7859 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7860 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7861 and insert the version number definitions from .version
7863 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7865 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7875 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7877 2002-08-10 Borut Razem <borut.razem AT siol.net>
7878 * src/SDCCmain.c (main):
7879 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7880 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7881 The consequence was that some temporary files were not removed.
7884 unification of code in functions tempfilename() and tempfile():
7885 function tempnam() is defined in Visual Studio 6.0 and .NET
7887 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7889 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7890 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

7904 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7905 added return 0 statements after assert() to make compiler happy
7907 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7908 added newline in the def file to keep MSC compiler satisfied
7910 * sdcc/src/z80/gen.c:
7911 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7912 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7913 - solved MSC error in function aopDump()
7915 * sdcc_vc.h: define PREFIX as "\\sdcc"
7917 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7969 Initialized the new field char *Processor field to NULL in all ports
7972 Compiler generated registers for interrupt context saving
7973 were not getting allocated.
7975 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7978 Fixed left shift. Will promote the left side of a left shift
7979 if a) left shifting more than size of operand or b) when assigned
7980 to something size > size of left side
7982 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8090 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8092 * sdcc/src/SDCCloop.c:
8093 Previous fix was not good. basic blocks that have "break" or "return" are
8094 not really partof a loop , but live ranges used in these blocks should
8095 be live thru the entire loop, so set partOfLoop but don't add them to
8098 2002-02-21 <johan AT FRIJA>
