688 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
690 * device/lib/printf_large.c: removed inline assembly for portability and
691 readability. Use printf_fast if speed or size are more important.
692 * src/pic16/gen.c: removed conditions around use of DEBUGpc
693 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
695 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
697 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
698 prevent compiler warning
700 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
702 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
703 moved to level 0 and declared as static. Also they are explicit
704 placed in access bank. This was necessery because some times they
705 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
706 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
707 optimizations. Currently only compare to unsigned char is implemented,
708 * src/pic16/gen.c: added fReturnIdx array,
709 * (struct resolvedIfx) is moved to gen.h and made public,
710 * (struct _G): added sregsAlloc and sregsAllocSet fields,
711 * (aopForSym): added an optimization to directly store in stack of
712 the operand of a SEND iCode,
713 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
714 but as registers instead (AOP_REG) using the fReturnIdx array,
715 * (pic16_freeAsmop): remove the freed register from the
717 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
719 * (pic16_popGetTempRegCond): changed function prototype, now
720 function takes also a bitVector argument v which holds the current
721 set of registers that are allocated for stack access by aopForSym,
722 registers allocated in aopForSym for accessing stack symbols are not
723 any more part of the functions usedRegs field,
724 * (genCall): some times aopOp is called for a stack variable to be
725 send, aopForSym might perform the push, if this is true make sure
726 that genCall doesn't push the variable twice by testing _G.resDirect,
727 * (genFunction): changed testing for unspecified interrupt number
728 from 256 to INTNO_UNSPEC,
729 * modified selection scheme of frame pointer generation. Previously
730 if function did use local registers a frame pointer was generated,
731 now a frame pointer is generated only if function has arguments
732 (that need PLUSW2 register access), or has stack arguments, or the
733 compiler is not instructed to omit the frame pointer,
734 * (genEndFunction): before restoring local registers that were saved
735 in the function preamble, also restore the registers that *might*
736 have been allocated for stack access,
737 * (genRet): removed some old comments,
738 * (genCmp, the active (RN's) version): added a call to the
739 pic16_genCmp_special function to perform the compare with a more
740 robust and optimized way,
741 * (genInline): a feature has been added in inline code generation,
742 which allows a wildcard variable substitution when writing inline
743 assembly. Code is incomplete and experimental therefore undocumented,
744 * (genCast): changed order of aopOp for result and right to allow
745 aopForSym to directly load the result if possible,
746 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
747 perform an optimized compare on some selected special occasions,
748 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
749 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
750 generate an IVT any more,
751 * src/pic16/main.c (pic16_optionsTable): added command line option
753 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
754 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
756 * src/pic16/NOTES: Raphael Neider added in list of active developers
757 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
758 jumptable_end to prevent bug #,
759 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
760 inCond and outCond fields,
761 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
762 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
763 turn off register spilling,
764 * (packRegsForOneUse): synced with other ports' versions although it
765 is not used currently,
766 * (pic16_packRegisters): added an optimization while reading
767 structure bitfields, some registers may be saved (malloc code is
768 decreased by 80 bytes)
770 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
772 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
773 left is a bitfield, if yes, then don't optimize assignment. Perhaps
774 this can be optimized more?
776 2005-03-10 Raphael Neider <rneider AT web.de>
778 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
779 genNearPointerGet): (hopefully) fixed access to bitfields via
780 pointers (p->bitN = x; and x = p->bitN; failed)
782 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
784 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

1414 Adding support for replacing ljmps with sjmps in jumptables
1415 generated for switch statements. For now you need to set the
1416 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1417 Now 4 algorithms for mcs51 jumptable generation are used:
1418 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1419 addresses loaded pc-relative for up to 112 cases and stack-pushing
1420 target addresses loaded with offset from dptr for up to 256 cases.

1447 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1448 to call when a stack overflow occurs,
1449 * (malloc.h): added CVS Id tag,
1450 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1452 * added libc directory. The current version of LibC contains string
1453 functions, ctype functions and macros and some functions of the
1454 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1455 be extensively tested in the future. Standard disclaimer here.
1456 Library is not automatically build yet. But one can build it by
1457 invoking 'make' inside the libc directory.
1458 * added ADC library under libio. Preliminary version yet.

1467 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1468 * (pic16_storeForReturn): optimized return of 0,
1469 * (genCmp): experimental code for new genCmp which uses PIC18's
1470 special compare&skip instructions. Initial tests fail some times
1471 with variables grater than 1 byte in size, so new code is disabled,
1472 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1474 * (genCast): began a fix to optimize the casting of a bit to another
1475 bit, now assigning a bitfield to another bitfield will fail, sorry,
1476 * src/pic16/main.c: disabled the use of lr-support feature,
1477 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1480 bits with offset (case PO_GPR_BIT),
1481 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1483 * (isBankInstruction): modified to return 0 for no banking instruction,
1484 and 1 for banking instruction,
1485 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1486 caused stop processing pCodes after a inline assembly block,
1487 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1488 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1489 registers when it shouldn't,
1490 * src/pic16/ralloc.c (allocReg): add preliminary support for
1491 supporting a limited set of temporary registers,
1493 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1495 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1496 genDataPointerSet): ensure assignments always copy in MSB to LSB
1498 (loadRegFromAop): recognize CLRH optimization,
1499 (genFunction): optimize RECEIVE iCodes in reentrant functions
1501 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1503 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4430 * src/pic/glue (pic14emitRegularMap),
4431 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4433 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
4435 * src/pic/pcode.c (PCodeID): commented out left over debug code
4437 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
4439 * support/valdiag/tests/overflow.c: added shift tests
4447 * src/pic/pcodepeep.c,
4448 * src/pic/pcoderegs.c,
4450 * src/pic/ralloc.h: applied patch from Slade Rich;
4451 added support for multiple code pages and multiple RAM banks on the
4452 PIC 14 port. The ASM files now no longer simply assume all the
4453 code / RAM are in the same page / bank. This means the linker can
4454 safely allocate code/RAM of separate ASM files to different pages/banks.
4455 * doc/sdccman.lyx: added Slade's tips
4456 * src/mcs51/peeph.def: fixed bug #880768

4465 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4468 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4469 strtof is not part of C89 and isn't included with Mac OS X.
4471 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4473 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4498 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4500 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4501 loaded with the linker search paths (-L arguments) and the libraries
4502 to be linked with the current source (-l arguments). Changes
4503 currently will affect only the pic16 port.
4504 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4505 include path the port specific paths and port specific libraries,
4506 * gplink command now contains the $3 argument,
4507 * src/pic16/device.h,
4508 * src/pic16/device.c,: structure PIC_device is made public and
4509 renamed to PIC16_device, the same for variable Pics which is renamed
4510 to Pics16. Updated all references to them.
4511 * src/pic16/glue.c (pic16glue): corrected bug with code
4512 initialization which bypassed the variable initializations block.

4522 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4524 Documenting changes from previous commits.
4525 * configure.in (version 1.56),
4526 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4527 when generating output files to configure the pic16 library,
4528 but now I've commented it out, since gputils aren't installed in the
4529 SF compile farm, so library won't compile
4531 * device/lib/Makefile.in (version 1.56): initially I've added in
4532 target 'all' the prerequestive 'model-pic16' so it compiled the
4533 pic16 library, but now I've commented it out for the same reasons
4535 * added targets 'model-pic16' and 'objects-pic16' to compile the
4537 * added target 'port-specific-objects-pic16' to handle the
4538 generated libraries and copy them into the build/ directory
4539 * added target 'clean-intermediate-pic16' to clean intermediate
4540 files into pic16 directory
4541 * in target 'installdirs' added line to create directory pic16 in
4542 the installation path
4544 * device/include/Makefile.in (version 1.11): in target 'install'
4545 added lines to copy all header files to installation path,
4546 * in target 'installdirs' added line create directory for pic16
4547 headers in the installation path

4562 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4563 option so that it actually works. Made it specific to the z80, since
4564 the gbz80 doesn't have these kinds of I/O ports.
4566 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4568 * device/include/z180.h,

4590 Mainly changes to support compilation of the device libraries
4591 * src/pic16/device.c: stack is allocated via symbol and not
4592 via literal number. The symbol is placed in the corresponding
4593 position of the data ram
4594 * (pic16_dump_section): relocatable and absolute uninitialized
4595 data are now emitted in sorted order to reduce section naming,
4596 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4597 weren't marked as being in the access bank,
4599 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4601 Added portion of GNU PIC Library under the directory
4602 device/include/pic16 and device/lib/pic16. These files
4603 contain the declarations of SFRs for the PIC18Fxx2 devices.
4604 The directory is initialized via configure from toplevel.
4606 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4608 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4634 all over. Telling LaTeX to be less strict with word spacing
4635 to better keep the right margin. Changed some notes about
4636 maintainance of the ports in section 3.2.1 - is it OK like this?
4638 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4676 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4678 * src/pic16/peeph.def: all peepholes with movff are commented out,
4679 because there is a problem in the pcode peep optimizer,
4680 * src/pic16/ralloc.c: the register allocator can now reuse local

4742 override default uninitialized data segment definition for
4743 devices only with SHAREBANK memory (reported from Erik Epetrich)
4744 * (pic14emitOverlay): modified to emit a commented overlay segment
4745 directive when no overlay data exist
4746 * (picglue): modified to emit uninitialized data segment
4747 according to udata_section_name

4832 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4834 PIC16 port related changes:
4835 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4836 added variable stackPos,
4838 * gen.c: genCall, assignResultValue: added support for
4839 pushing/retrieving function parameters to/from stack,
4840 genFunction,genEndFunction: setup stack frame for the
4842 genAddrOf: will be changed according to bug 863624
4844 * added files genutils.c and genutils.h which contain gen*
4845 debugged and optimised functions extracted from gen.c
4847 * glue.c: added variable 'externs' which holds extern symbols,
4848 pic16emitRegularMap: is modified to properly handle relocatable
4849 symbols under the new scheme,
4850 pic16createInterruptVect: is modified
4851 pic16printPublics: is modified to emit 'global' assembler directives,
4852 added pic16_printExterns to print extern symbols,
4853 pic16glue: initializes stack/frame pointer in the beginning of
4854 the assembly output. Temporary hack, will be corrected later,
4855 because gplink yet does not support stack and SDCC does not
4856 yet support a type of crt0.o object to create the final binary.
4858 * Removed many lines that contain 8051 legacy code.
4859 * The code is finally placed under a 'code' directive.
4860 * Added port specific options.
4862 * _process_pragma: simplified since now we do not need *special*
4863 include file to define SFR registers. But a separate header
4864 will be needed. This will be developed later.
4865 * _pic16_parseOptions: added, parses port specific options:
4866 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4867 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4868 --preplace-udata-with=
4870 * _pic16_setDefaultOptions: modified to initialize section names,
4871 but hack is temporarly out of order since it needs improvement.
4872 * _pic16_genAssemblerPreamble: configuration words are emitted by
4873 their address instead of their name. This part is incomplete and
4874 supports only the 18Fxx2 devices. Other devices will emit an error
4875 during assembly since they do not contain the same set of config
4877 * _pic16_genIVT: is modified,
4879 * pcode.c: added definitions for some hardware registers that are needed
4881 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4882 All PCI entries are updated. Now LFSR is supported.
4883 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4884 * added pic16_newpCodeOpLit2 to support instructions with
4885 two literal arguments
4886 * pic16_pCode2str: corrected code that emits assembler instructions
4887 with two literal operands and those that have an access bit modifier
4888 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4889 this fixes a bug which caused some labels to be lost, when an
4890 assembler directive was added, i.e. banksel,
4891 * pic16_FixRegisterBanking: improved logic that causes the insertion
4893 * InlineFunction: functions that are called once, are not any more
4894 inlined. This can be a port option in the future,
4896 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4898 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4899 hold the corresponding uninitialized symbols,
4900 * pic16_allocProcessorRegister: registers have explicit marked the
4902 * pic16_allocInternalRegister: registers are explicit marked as
4904 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4905 processing list, so bit registers were lost,
4908 * ralloc.h: added field 'accessBank' and original symbol operand
4909 in register definition,
4910 * removed the field isMapped from register definition,
4912 ** Several functions have been removed from various sources:
4913 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4914 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4915 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4916 pic16_assignRelocatableRegisters
4918 ** others have been introduced:
4919 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4920 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4922 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4924 * support/scripts/inc2h.pl: changed definition of BIT_AT
4925 to emit 'sbit at' instead of 'bit at'. This was a request.
4927 PIC16 port related preliminary changes:
4928 * gen.c: prefixed function popRegFromString with
4929 pic16_ and all references to it corrected
4930 * pcode.c: all pic16_pc_* hardware registers prefixed
4931 with underscore (_),
4932 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4933 * ralloc.c: newReg(): when register is REG_SFR then
4934 set address to rIdx,
4935 pic16_allocProcessorRegister(): marks register wasUsed=0
4936 pic16_writeUsedRegs(): added a call to assign processor
4937 registers via pic16_assignFixedRegisters
4939 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4941 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4942 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4943 variables in unused register banks. Also the SSEG is placed
4944 wherever there is enough space for it, and IDATA can be anywhere
4945 in internal RAM. For now compile using -Wl-Y[stack_size].
4946 The mem file is different for this option as well, since it
4947 makes no sense of talking about DSEG lenght.
4949 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4951 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5196 * src/SDCCast.c (decorateType): disabled a transformation I added in
5197 revision 1.188 (access to fields of a structure at an absolute address);
5198 it breaks with bitfields, extern declarations, and gcse analysis.
5199 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5200 could be assigned through a pointer, so don't complain.

5924 reported in bug #800609
5926 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
5928 * Top header beautifications in src/pic16 directory:
5929 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
5930 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
5931 pcoderegs.h, ralloc.c, ralloc.h
5932 * main.c: added top header and GPL license notice
5933 * pcode.c: fixed the if-conditional warning
5935 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
5937 * device/lib/_mullong.c: replaced int by short for gcc
5939 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5941 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
5942 and JUMPTABLE iCodes properly now (worked by accident before)
5943 * src/mcs51/gen.c (leftRightUseAcc),
5944 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5945 iCode properly now. Use getSize instead of nRegs since a & b
5946 aren't part of the nRegs tally.
5948 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5950 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5951 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5952 before instructions that use the _STATUS register
5954 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5956 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5957 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5958 fetching of the pointer
5959 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5960 copied from genNearPointerSet()
5961 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5962 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5963 If they pop r0/r1 they must be called in the opposite order than aopOp().
5964 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5965 (resp. --stack-auto), prepared for --xstack
5967 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5971 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5973 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5974 these ports have their own __sdcc_external_start()
5976 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5978 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5979 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5980 type for bits was changed. It resulted in bit variables becoming
5981 global, which is not permitted in PIC 14 assembly output.
5983 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5985 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5987 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5989 Z80 and MCS51 linkers complaint if a public symbol is defined
5990 in more than one library module:
5994 * as/mcs51/Makefile.in
5996 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5998 A few small changes that speed up the peephole optimizer.
6002 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6004 Try to make the peephole optimizer smarter by maintaining
6005 an association between the assembly source code and the
6006 iCodes that originated them. Put this information to use
6007 with a new peephole rule condition "notVolatile" so that
6008 the rules can be aggressive yet still safe.
6013 * src/mcs51/peeph.def
6015 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6019 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6020 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6021 if the left or right operand symbols have the accuse flag set.
6023 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6025 Changed the type of the result of the ! (NOT) operator to char;
6026 previously it returned the same type as the source. This allows
6027 us to eliminate all the genFloatNot functions (all of its target
6028 implementations were very buggy) since !float can use the same
6031 * src/SDCCicode.c (ast2iCode): ! returns char
6032 * src/mcs51/gen.c (genNot, genNotFloat),
6033 * src/ds390/gen.c (genNot, genNotFloat),
6034 * src/z80/gen.c (genNot, genNotFloat),
6035 * src/pic/gen.c (genNot, genNotFloat),
6036 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6038 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6040 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6041 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6042 during interrupts. Ensure WSAVE is located at a shared bank address.
6043 2. Fixed page selection in some places
6044 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6045 the registers name strings.
6046 4. Fixed "signed / unsigned compare" compiler warnings.
6047 5. The PIC port manages its own allocation of the general purpose
6048 registers, but makes no attempt to reuse them. As a result when
6049 compiling it soon runs out of general purpose registers. Some
6050 additional code was added to the files pcode.c and device.c to walk
6051 through the function call tree and rename the registers so that they
6061 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6062 genPlus() & genMinus() when the result is the same as left or right

6068 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6070 Made bitfield a distinct type from bit so that bitfields
6071 convert as per ANSI C and bits retain their traditional
6072 boolean style behaviour. Implemented bitfield support in
6080 * src/ds390/gen.c: bit v bitfield split
6081 * src/z80/gen.c: New support for bitfields
6082 * support/regression/tests/bitfields.c: reenabled z80,
6085 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6087 Rules 246.x, 247.x relate to bitfields, the others speed up
6088 access to xdata mapped I/O devices.
6090 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6092 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6094 Cleaned up genPackBits and genUnpackBits and added two helper
6095 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6096 for literal assignments in genPackBits (thanks to Frieder for
6102 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6104 Fixed bug #748310 (pointer to function type mishandled when the
6105 function name is omitted). Also fixed a SIGSEGV when a function
6106 attribute (reentrant, etc) is used on a non-function or on a
6107 function but misplaced before the parameter list.
6109 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6111 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6112 * support/Util/SDCCerr.h,
6113 * support/Util/SDCCerr.c: Added func attr misuse error msg
6115 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6117 Fixed bug #787649 by anonymous
6118 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6134 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6136 Made the constant following the "interrupt" keyword optional. If
6137 omitted, the function will not automatically be given an entry
6138 in the interrupt vector table (similar to #pragma NOIV, but
6139 less syntacticly kludgy). The interrupt number is also now
6140 range checked. Also fixed a bug in the high order bit example
6147 * support/Util/SDCCerr.c
6148 * support/Util/SDCCerr.h
6151 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6154 * src/SDCCicode.c (operandOperation): rewritten some ops
6155 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6156 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6158 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6159 be re-activated by defining REDUCE_LITERALS)
6160 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6161 unsigned, but are signed by default
6162 * src/SDCCval.c (constVal): rearranged
6163 * src/SDCCval.c (valMod): preliminary fix
6164 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6207 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6208 * src/SDCCval.c (valDiv, valMod): fixed signdness
6209 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6210 signedness of modulo, left and right shift

6616 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6617 the regression tests I'm not brave enough to enable 245.b, 245.c
6618 * doc/sdccman.lyx: added latex preamble for hyperref package.
6619 Using pdflatex this will give you a hyperlinked pdf file with
6620 bookmarks. (prepend '%' before /usepackage if this breaks something)

6658 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6660 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6661 it can be defined with CFLAGS when running configure
6662 * src/SDCCmain.c: fixed compiling + linking with object files
6664 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6666 * configure.in: configure for pic16 port,
6667 added --disable-pic16-port
6668 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6669 * src/SDCCmain.c: linkOptions is changed to set *,
6670 added if/endif conditional macros to remove options help
6671 messages from optionsTable when a port is not configured, added
6672 support for the PIc16 port in the ports table, when executing
6673 the compiler with no port specified on command line, a default
6674 port is selected with the new macro DEFAULT_PORT which is
6675 defined in port.h, in setDefaultOptions() linkOptions is removed
6676 from initialization assignment, since now it is a set,
6677 parseCmdLine uses setParseWithComma for linkOptions, in
6678 linkEdit() linkOptions are accessed with new function indexSet()
6679 which returns the i'th item of a set variable. See SDCCset.c, in
6680 linkEdit() when calling buildCmdLine(), added linkOptions as
6681 last argument. Now users can pass arguments to gplink via the
6682 -Wl option, main() uses pic16glue() to glue up pic16 programs
6683 * src/SDCCpeeph.c: various changes to support pic16

6694 * src/pic16/glue.c: commented out some error producing lines
6695 * src/pic16/main.c: __config directives are commented out to stop
6696 gpasm complaining and test the linkage with gplink, _linkCmd and
6697 _asmCmd changed to be more gplink and gpasm friendly
6698 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6699 produced an error when parsed, peep rule 12 is added to utilize
6700 movff, but it is commented out since the pCode does not support
6701 yet a command with 2 address arguments
6703 2003-05-18 <johan AT balder>
6705 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6706 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6730 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6732 2003-05-11 Borut Razem <borut.razem AT siol.net>
6734 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6735 the path of bin directory, so that PATH is the only env. variable, which has to be set
6736 in case of standard installation.
6737 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7769 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7770 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7771 following files to include the previous two files: aslink.dsp,
7772 Makefile.aslink, Makefile.bcc, and Makefile.in.
7774 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7775 .adb instead of .cdb
7777 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7779 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7780 value from option --iram-size.
7782 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7784 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7787 2002-09-18 <wiml AT hhhh.org>
7789 * SDCClrange.h: exposed setFromRange() and setToRange()
7790 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7791 packRegsForAccUse() (bug 542397)
7792 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7793 multiple times and emitting the fetch operations more than once
7794 added aopGetUsesAcc() function to allow binary operators to
7795 fetch their operands in the correct order; made genMinus() emit
7796 compact code for X = LITERAL - Y
7798 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7799 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7800 sprintf() in line 1267.
7802 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7806 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7807 Changes to aslink (All the changes are marked with 'JCF'):
7809 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7812 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7813 area BSEG. Also moves, if possible, the DATA area down into the internal
7814 ram so more space is available.
7816 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7819 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7820 not bytes. Function summary() which creates a memory usage summary
7821 file with extension .mem. Reports of overlaping stack and small stack
7822 size. If the space for the stack is less than 16 bytes aslink trows a
7825 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7826 the 8051. Option 'y' for memory summary output file.
7828 Changes to sdcc (All the changes are marked with 'JCF'):
7830 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7832 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7833 overlaying area for it (uses RegBankUsed[4]).
7835 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7836 bank zero as used by default. By default aslink locates the stack
7837 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7838 the creation of the .mem file. Delegates the allocation of data area
7839 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7840 the begining of the stack area to aslink.
7842 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7843 glue() in SDCCglue.c creates an area for it.

7846 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7847 sdcc/src/pic/glue.c:
7848 introduced atexit() handler for teporay files removal in case of
7849 errors, assertions, ...
7851 2002-08-29 Borut Razem <borut.razem AT siol.net>
7852 * sdcc/support/cpp2/auto-host_vc_in.h:
7853 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7854 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7855 Maybe there is a similar problem with BORLANDC? It should be checked!
7857 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7858 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7859 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7860 was not executed, and the compiler (cl) launched a warning:
7861 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7863 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7864 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7866 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7867 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7869 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7870 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7871 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7872 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7873 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7874 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7875 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7876 - added Release configuration in VS projects
7877 - review of compiler an linker options
7878 - VC .exe files are generated in bin_vc directory, not to interfere
7879 with binaries generated from other projects (cygwin, mingw, bcc ...)
7881 * sdcc/src/yacc.dsp: added
7883 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7884 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7885 and insert the version number definitions from .version
7887 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7889 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7890 added - genarate auto-host.h using auto-host_vc_in.h as template
7893 removed from CVS, generated automatically
7895 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7896 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7898 2002-08-11 Borut Razem <borut.razem AT siol.net>
7899 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7901 2002-08-10 Borut Razem <borut.razem AT siol.net>
7902 * src/SDCCmain.c (main):
7903 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7904 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7905 The consequence was that some temporary files were not removed.
7908 unification of code in functions tempfilename() and tempfile():
7909 function tempnam() is defined in Visual Studio 6.0 and .NET
7911 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7913 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7914 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7915 - removed compiler command line option /WX: Treats all warnings as errors
7916 - update a list of source files, included into the project
7918 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7919 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7920 changed project type to Generic Project so that can be correcly converted to VS.NET project
7922 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7924 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7926 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7928 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7929 added return 0 statements after assert() to make compiler happy
7931 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7932 added newline in the def file to keep MSC compiler satisfied
7934 * sdcc/src/z80/gen.c:
7935 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7936 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7937 - solved MSC error in function aopDump()
7939 * sdcc_vc.h: define PREFIX as "\\sdcc"
7941 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7942 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7990 Added -p option. Allows port dependent processor to be specified.
7993 Initialized the new field char *Processor field to NULL in all ports
7996 Compiler generated registers for interrupt context saving
7997 were not getting allocated.
7999 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8002 Fixed left shift. Will promote the left side of a left shift
8003 if a) left shifting more than size of operand or b) when assigned
8004 to something size > size of left side
8006 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8116 * sdcc/src/SDCCloop.c:
8117 Previous fix was not good. basic blocks that have "break" or "return" are
8118 not really partof a loop , but live ranges used in these blocks should
8119 be live thru the entire loop, so set partOfLoop but don't add them to
8122 2002-02-21 <johan AT FRIJA>
8124 * src/SDCCcse.c: fixed bug #514308
8126 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8132 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8134 2002-02-10 Karl Bongers <karl AT turbobit.com>
