602 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
604 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
605 * src/z80/main.c (_keywords[]),
606 * src/SDCCglobal.h (struct options),

693 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
695 * device/lib/printf_large.c: removed inline assembly for portability and
696 readability. Use printf_fast if speed or size are more important.
697 * src/pic16/gen.c: removed conditions around use of DEBUGpc
698 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
700 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
702 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
703 prevent compiler warning
705 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
707 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
708 moved to level 0 and declared as static. Also they are explicit
709 placed in access bank. This was necessery because some times they
710 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
711 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
712 optimizations. Currently only compare to unsigned char is implemented,
713 * src/pic16/gen.c: added fReturnIdx array,
714 * (struct resolvedIfx) is moved to gen.h and made public,
715 * (struct _G): added sregsAlloc and sregsAllocSet fields,
716 * (aopForSym): added an optimization to directly store in stack of
717 the operand of a SEND iCode,
718 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
719 but as registers instead (AOP_REG) using the fReturnIdx array,
720 * (pic16_freeAsmop): remove the freed register from the
722 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
724 * (pic16_popGetTempRegCond): changed function prototype, now
725 function takes also a bitVector argument v which holds the current
726 set of registers that are allocated for stack access by aopForSym,
727 registers allocated in aopForSym for accessing stack symbols are not
728 any more part of the functions usedRegs field,
729 * (genCall): some times aopOp is called for a stack variable to be
730 send, aopForSym might perform the push, if this is true make sure
731 that genCall doesn't push the variable twice by testing _G.resDirect,
732 * (genFunction): changed testing for unspecified interrupt number
733 from 256 to INTNO_UNSPEC,
734 * modified selection scheme of frame pointer generation. Previously
735 if function did use local registers a frame pointer was generated,
736 now a frame pointer is generated only if function has arguments
737 (that need PLUSW2 register access), or has stack arguments, or the
738 compiler is not instructed to omit the frame pointer,
739 * (genEndFunction): before restoring local registers that were saved
740 in the function preamble, also restore the registers that *might*
741 have been allocated for stack access,
742 * (genRet): removed some old comments,
743 * (genCmp, the active (RN's) version): added a call to the
744 pic16_genCmp_special function to perform the compare with a more
745 robust and optimized way,
746 * (genInline): a feature has been added in inline code generation,
747 which allows a wildcard variable substitution when writing inline
748 assembly. Code is incomplete and experimental therefore undocumented,
749 * (genCast): changed order of aopOp for result and right to allow
750 aopForSym to directly load the result if possible,
751 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
752 perform an optimized compare on some selected special occasions,
753 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
754 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
755 generate an IVT any more,
756 * src/pic16/main.c (pic16_optionsTable): added command line option
758 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
759 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
761 * src/pic16/NOTES: Raphael Neider added in list of active developers
762 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
763 jumptable_end to prevent bug #,
764 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
765 inCond and outCond fields,
766 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
767 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
768 turn off register spilling,
769 * (packRegsForOneUse): synced with other ports' versions although it
770 is not used currently,
771 * (pic16_packRegisters): added an optimization while reading
772 structure bitfields, some registers may be saved (malloc code is
773 decreased by 80 bytes)
775 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
777 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
778 left is a bitfield, if yes, then don't optimize assignment. Perhaps
779 this can be optimized more?
781 2005-03-10 Raphael Neider <rneider AT web.de>
783 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
784 genNearPointerGet): (hopefully) fixed access to bitfields via
785 pointers (p->bitN = x; and x = p->bitN; failed)
787 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
789 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1419 Adding support for replacing ljmps with sjmps in jumptables
1420 generated for switch statements. For now you need to set the
1421 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1422 Now 4 algorithms for mcs51 jumptable generation are used:
1423 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1424 addresses loaded pc-relative for up to 112 cases and stack-pushing
1425 target addresses loaded with offset from dptr for up to 256 cases.

1452 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1453 to call when a stack overflow occurs,
1454 * (malloc.h): added CVS Id tag,
1455 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1457 * added libc directory. The current version of LibC contains string
1458 functions, ctype functions and macros and some functions of the
1459 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1460 be extensively tested in the future. Standard disclaimer here.
1461 Library is not automatically build yet. But one can build it by
1462 invoking 'make' inside the libc directory.
1463 * added ADC library under libio. Preliminary version yet.
1465 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1472 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1473 * (pic16_storeForReturn): optimized return of 0,
1474 * (genCmp): experimental code for new genCmp which uses PIC18's
1475 special compare&skip instructions. Initial tests fail some times
1476 with variables grater than 1 byte in size, so new code is disabled,
1477 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1479 * (genCast): began a fix to optimize the casting of a bit to another
1480 bit, now assigning a bitfield to another bitfield will fail, sorry,
1481 * src/pic16/main.c: disabled the use of lr-support feature,
1482 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1485 bits with offset (case PO_GPR_BIT),
1486 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1488 * (isBankInstruction): modified to return 0 for no banking instruction,
1489 and 1 for banking instruction,
1490 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1491 caused stop processing pCodes after a inline assembly block,
1492 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1493 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1494 registers when it shouldn't,
1495 * src/pic16/ralloc.c (allocReg): add preliminary support for
1496 supporting a limited set of temporary registers,
1498 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1500 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1501 genDataPointerSet): ensure assignments always copy in MSB to LSB
1503 (loadRegFromAop): recognize CLRH optimization,
1504 (genFunction): optimize RECEIVE iCodes in reentrant functions
1506 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4435 * src/pic/glue (pic14emitRegularMap),
4436 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4438 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
4440 * src/pic/pcode.c (PCodeID): commented out left over debug code
4442 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
4444 * support/valdiag/tests/overflow.c: added shift tests
4452 * src/pic/pcodepeep.c,
4453 * src/pic/pcoderegs.c,
4455 * src/pic/ralloc.h: applied patch from Slade Rich;
4456 added support for multiple code pages and multiple RAM banks on the
4457 PIC 14 port. The ASM files now no longer simply assume all the
4458 code / RAM are in the same page / bank. This means the linker can
4459 safely allocate code/RAM of separate ASM files to different pages/banks.
4460 * doc/sdccman.lyx: added Slade's tips
4461 * src/mcs51/peeph.def: fixed bug #880768

4470 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4473 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4474 strtof is not part of C89 and isn't included with Mac OS X.
4476 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4478 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4503 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4505 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4506 loaded with the linker search paths (-L arguments) and the libraries
4507 to be linked with the current source (-l arguments). Changes
4508 currently will affect only the pic16 port.
4509 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4510 include path the port specific paths and port specific libraries,
4511 * gplink command now contains the $3 argument,
4512 * src/pic16/device.h,
4513 * src/pic16/device.c,: structure PIC_device is made public and
4514 renamed to PIC16_device, the same for variable Pics which is renamed
4515 to Pics16. Updated all references to them.
4516 * src/pic16/glue.c (pic16glue): corrected bug with code
4517 initialization which bypassed the variable initializations block.
4519 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4520 COMPILE_FLAGS and added the --nostdinc option
4522 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4529 Documenting changes from previous commits.
4530 * configure.in (version 1.56),
4531 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4532 when generating output files to configure the pic16 library,
4533 but now I've commented it out, since gputils aren't installed in the
4534 SF compile farm, so library won't compile
4536 * device/lib/Makefile.in (version 1.56): initially I've added in
4537 target 'all' the prerequestive 'model-pic16' so it compiled the
4538 pic16 library, but now I've commented it out for the same reasons
4540 * added targets 'model-pic16' and 'objects-pic16' to compile the
4542 * added target 'port-specific-objects-pic16' to handle the
4543 generated libraries and copy them into the build/ directory
4544 * added target 'clean-intermediate-pic16' to clean intermediate
4545 files into pic16 directory
4546 * in target 'installdirs' added line to create directory pic16 in
4547 the installation path
4549 * device/include/Makefile.in (version 1.11): in target 'install'
4550 added lines to copy all header files to installation path,
4551 * in target 'installdirs' added line create directory for pic16
4552 headers in the installation path

4567 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4568 option so that it actually works. Made it specific to the z80, since
4569 the gbz80 doesn't have these kinds of I/O ports.
4571 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4573 * device/include/z180.h,

4595 Mainly changes to support compilation of the device libraries
4596 * src/pic16/device.c: stack is allocated via symbol and not
4597 via literal number. The symbol is placed in the corresponding
4598 position of the data ram
4599 * (pic16_dump_section): relocatable and absolute uninitialized
4600 data are now emitted in sorted order to reduce section naming,
4601 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4602 weren't marked as being in the access bank,
4604 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4606 Added portion of GNU PIC Library under the directory
4607 device/include/pic16 and device/lib/pic16. These files
4608 contain the declarations of SFRs for the PIC18Fxx2 devices.
4609 The directory is initialized via configure from toplevel.
4611 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4613 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4639 all over. Telling LaTeX to be less strict with word spacing
4640 to better keep the right margin. Changed some notes about
4641 maintainance of the ports in section 3.2.1 - is it OK like this?
4643 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4681 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4683 * src/pic16/peeph.def: all peepholes with movff are commented out,
4684 because there is a problem in the pcode peep optimizer,
4685 * src/pic16/ralloc.c: the register allocator can now reuse local

4747 override default uninitialized data segment definition for
4748 devices only with SHAREBANK memory (reported from Erik Epetrich)
4749 * (pic14emitOverlay): modified to emit a commented overlay segment
4750 directive when no overlay data exist
4751 * (picglue): modified to emit uninitialized data segment
4752 according to udata_section_name

4837 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4839 PIC16 port related changes:
4840 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4841 added variable stackPos,
4843 * gen.c: genCall, assignResultValue: added support for
4844 pushing/retrieving function parameters to/from stack,
4845 genFunction,genEndFunction: setup stack frame for the
4847 genAddrOf: will be changed according to bug 863624
4849 * added files genutils.c and genutils.h which contain gen*
4850 debugged and optimised functions extracted from gen.c
4852 * glue.c: added variable 'externs' which holds extern symbols,
4853 pic16emitRegularMap: is modified to properly handle relocatable
4854 symbols under the new scheme,
4855 pic16createInterruptVect: is modified
4856 pic16printPublics: is modified to emit 'global' assembler directives,
4857 added pic16_printExterns to print extern symbols,
4858 pic16glue: initializes stack/frame pointer in the beginning of
4859 the assembly output. Temporary hack, will be corrected later,
4860 because gplink yet does not support stack and SDCC does not
4861 yet support a type of crt0.o object to create the final binary.
4863 * Removed many lines that contain 8051 legacy code.
4864 * The code is finally placed under a 'code' directive.
4865 * Added port specific options.
4867 * _process_pragma: simplified since now we do not need *special*
4868 include file to define SFR registers. But a separate header
4869 will be needed. This will be developed later.
4870 * _pic16_parseOptions: added, parses port specific options:
4871 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4872 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4873 --preplace-udata-with=
4875 * _pic16_setDefaultOptions: modified to initialize section names,
4876 but hack is temporarly out of order since it needs improvement.
4877 * _pic16_genAssemblerPreamble: configuration words are emitted by
4878 their address instead of their name. This part is incomplete and
4879 supports only the 18Fxx2 devices. Other devices will emit an error
4880 during assembly since they do not contain the same set of config
4882 * _pic16_genIVT: is modified,
4884 * pcode.c: added definitions for some hardware registers that are needed
4886 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4887 All PCI entries are updated. Now LFSR is supported.
4888 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4889 * added pic16_newpCodeOpLit2 to support instructions with
4890 two literal arguments
4891 * pic16_pCode2str: corrected code that emits assembler instructions
4892 with two literal operands and those that have an access bit modifier
4893 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4894 this fixes a bug which caused some labels to be lost, when an
4895 assembler directive was added, i.e. banksel,
4896 * pic16_FixRegisterBanking: improved logic that causes the insertion
4898 * InlineFunction: functions that are called once, are not any more
4899 inlined. This can be a port option in the future,
4901 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4903 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4904 hold the corresponding uninitialized symbols,
4905 * pic16_allocProcessorRegister: registers have explicit marked the
4907 * pic16_allocInternalRegister: registers are explicit marked as
4909 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4910 processing list, so bit registers were lost,
4913 * ralloc.h: added field 'accessBank' and original symbol operand
4914 in register definition,
4915 * removed the field isMapped from register definition,
4917 ** Several functions have been removed from various sources:
4918 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4919 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4920 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4921 pic16_assignRelocatableRegisters
4923 ** others have been introduced:
4924 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4925 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4927 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4929 * support/scripts/inc2h.pl: changed definition of BIT_AT
4930 to emit 'sbit at' instead of 'bit at'. This was a request.
4932 PIC16 port related preliminary changes:
4933 * gen.c: prefixed function popRegFromString with
4934 pic16_ and all references to it corrected
4935 * pcode.c: all pic16_pc_* hardware registers prefixed
4936 with underscore (_),
4937 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4938 * ralloc.c: newReg(): when register is REG_SFR then
4939 set address to rIdx,
4940 pic16_allocProcessorRegister(): marks register wasUsed=0
4941 pic16_writeUsedRegs(): added a call to assign processor
4942 registers via pic16_assignFixedRegisters
4944 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4946 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4947 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4948 variables in unused register banks. Also the SSEG is placed
4949 wherever there is enough space for it, and IDATA can be anywhere
4950 in internal RAM. For now compile using -Wl-Y[stack_size].
4951 The mem file is different for this option as well, since it
4952 makes no sense of talking about DSEG lenght.
4954 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4956 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5201 * src/SDCCast.c (decorateType): disabled a transformation I added in
5202 revision 1.188 (access to fields of a structure at an absolute address);
5203 it breaks with bitfields, extern declarations, and gcse analysis.
5204 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5205 could be assigned through a pointer, so don't complain.

5934 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
5935 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
5936 pcoderegs.h, ralloc.c, ralloc.h
5937 * main.c: added top header and GPL license notice
5938 * pcode.c: fixed the if-conditional warning
5940 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
5942 * device/lib/_mullong.c: replaced int by short for gcc
5944 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5946 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
5947 and JUMPTABLE iCodes properly now (worked by accident before)
5948 * src/mcs51/gen.c (leftRightUseAcc),
5949 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5950 iCode properly now. Use getSize instead of nRegs since a & b
5951 aren't part of the nRegs tally.
5953 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5955 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5956 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5957 before instructions that use the _STATUS register
5959 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5961 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5962 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5963 fetching of the pointer
5964 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5965 copied from genNearPointerSet()
5966 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5967 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5968 If they pop r0/r1 they must be called in the opposite order than aopOp().
5969 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5970 (resp. --stack-auto), prepared for --xstack
5972 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5976 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5978 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5979 these ports have their own __sdcc_external_start()
5981 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5983 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5984 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5985 type for bits was changed. It resulted in bit variables becoming
5986 global, which is not permitted in PIC 14 assembly output.
5988 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5990 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5992 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5994 Z80 and MCS51 linkers complaint if a public symbol is defined
5995 in more than one library module:
5999 * as/mcs51/Makefile.in
6001 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6003 A few small changes that speed up the peephole optimizer.
6007 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6009 Try to make the peephole optimizer smarter by maintaining
6010 an association between the assembly source code and the
6011 iCodes that originated them. Put this information to use
6012 with a new peephole rule condition "notVolatile" so that
6013 the rules can be aggressive yet still safe.
6018 * src/mcs51/peeph.def
6020 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6024 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6025 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6026 if the left or right operand symbols have the accuse flag set.
6028 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6030 Changed the type of the result of the ! (NOT) operator to char;
6031 previously it returned the same type as the source. This allows
6032 us to eliminate all the genFloatNot functions (all of its target
6033 implementations were very buggy) since !float can use the same
6036 * src/SDCCicode.c (ast2iCode): ! returns char
6037 * src/mcs51/gen.c (genNot, genNotFloat),
6038 * src/ds390/gen.c (genNot, genNotFloat),
6039 * src/z80/gen.c (genNot, genNotFloat),
6040 * src/pic/gen.c (genNot, genNotFloat),
6041 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6043 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6045 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6046 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6047 during interrupts. Ensure WSAVE is located at a shared bank address.
6048 2. Fixed page selection in some places
6049 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6050 the registers name strings.
6051 4. Fixed "signed / unsigned compare" compiler warnings.
6052 5. The PIC port manages its own allocation of the general purpose
6053 registers, but makes no attempt to reuse them. As a result when
6054 compiling it soon runs out of general purpose registers. Some
6055 additional code was added to the files pcode.c and device.c to walk
6056 through the function call tree and rename the registers so that they
6066 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6067 genPlus() & genMinus() when the result is the same as left or right

6073 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6075 Made bitfield a distinct type from bit so that bitfields
6076 convert as per ANSI C and bits retain their traditional
6077 boolean style behaviour. Implemented bitfield support in
6085 * src/ds390/gen.c: bit v bitfield split
6086 * src/z80/gen.c: New support for bitfields
6087 * support/regression/tests/bitfields.c: reenabled z80,
6090 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6092 Rules 246.x, 247.x relate to bitfields, the others speed up
6093 access to xdata mapped I/O devices.
6095 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6097 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6099 Cleaned up genPackBits and genUnpackBits and added two helper
6100 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6101 for literal assignments in genPackBits (thanks to Frieder for
6107 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6109 Fixed bug #748310 (pointer to function type mishandled when the
6110 function name is omitted). Also fixed a SIGSEGV when a function
6111 attribute (reentrant, etc) is used on a non-function or on a
6112 function but misplaced before the parameter list.
6114 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6116 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6117 * support/Util/SDCCerr.h,
6118 * support/Util/SDCCerr.c: Added func attr misuse error msg

6139 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6141 Made the constant following the "interrupt" keyword optional. If
6142 omitted, the function will not automatically be given an entry
6143 in the interrupt vector table (similar to #pragma NOIV, but
6144 less syntacticly kludgy). The interrupt number is also now
6145 range checked. Also fixed a bug in the high order bit example
6152 * support/Util/SDCCerr.c
6153 * support/Util/SDCCerr.h
6156 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6159 * src/SDCCicode.c (operandOperation): rewritten some ops
6160 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6161 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6163 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6164 be re-activated by defining REDUCE_LITERALS)
6165 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6166 unsigned, but are signed by default
6167 * src/SDCCval.c (constVal): rearranged
6168 * src/SDCCval.c (valMod): preliminary fix
6169 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6212 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6213 * src/SDCCval.c (valDiv, valMod): fixed signdness
6214 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6215 signedness of modulo, left and right shift

6621 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6622 the regression tests I'm not brave enough to enable 245.b, 245.c
6623 * doc/sdccman.lyx: added latex preamble for hyperref package.
6624 Using pdflatex this will give you a hyperlinked pdf file with
6625 bookmarks. (prepend '%' before /usepackage if this breaks something)

6663 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6665 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6666 it can be defined with CFLAGS when running configure
6667 * src/SDCCmain.c: fixed compiling + linking with object files
6669 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6671 * configure.in: configure for pic16 port,
6672 added --disable-pic16-port
6673 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6674 * src/SDCCmain.c: linkOptions is changed to set *,
6675 added if/endif conditional macros to remove options help
6676 messages from optionsTable when a port is not configured, added
6677 support for the PIc16 port in the ports table, when executing
6678 the compiler with no port specified on command line, a default
6679 port is selected with the new macro DEFAULT_PORT which is
6680 defined in port.h, in setDefaultOptions() linkOptions is removed
6681 from initialization assignment, since now it is a set,
6682 parseCmdLine uses setParseWithComma for linkOptions, in
6683 linkEdit() linkOptions are accessed with new function indexSet()
6684 which returns the i'th item of a set variable. See SDCCset.c, in
6685 linkEdit() when calling buildCmdLine(), added linkOptions as
6686 last argument. Now users can pass arguments to gplink via the
6687 -Wl option, main() uses pic16glue() to glue up pic16 programs
6688 * src/SDCCpeeph.c: various changes to support pic16

6699 * src/pic16/glue.c: commented out some error producing lines
6700 * src/pic16/main.c: __config directives are commented out to stop
6701 gpasm complaining and test the linkage with gplink, _linkCmd and
6702 _asmCmd changed to be more gplink and gpasm friendly
6703 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6704 produced an error when parsed, peep rule 12 is added to utilize
6705 movff, but it is commented out since the pCode does not support
6706 yet a command with 2 address arguments
6708 2003-05-18 <johan AT balder>
6710 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6711 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6737 2003-05-11 Borut Razem <borut.razem AT siol.net>
6739 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6740 the path of bin directory, so that PATH is the only env. variable, which has to be set
6741 in case of standard installation.
6742 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7774 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7775 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7776 following files to include the previous two files: aslink.dsp,
7777 Makefile.aslink, Makefile.bcc, and Makefile.in.
7779 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7780 .adb instead of .cdb
7782 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7784 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7785 value from option --iram-size.
7787 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7789 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7792 2002-09-18 <wiml AT hhhh.org>
7794 * SDCClrange.h: exposed setFromRange() and setToRange()
7795 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7796 packRegsForAccUse() (bug 542397)
7797 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7798 multiple times and emitting the fetch operations more than once
7799 added aopGetUsesAcc() function to allow binary operators to
7800 fetch their operands in the correct order; made genMinus() emit
7801 compact code for X = LITERAL - Y
7803 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7804 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7805 sprintf() in line 1267.
7807 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7811 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7812 Changes to aslink (All the changes are marked with 'JCF'):
7814 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7817 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7818 area BSEG. Also moves, if possible, the DATA area down into the internal
7819 ram so more space is available.
7821 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7824 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7825 not bytes. Function summary() which creates a memory usage summary
7826 file with extension .mem. Reports of overlaping stack and small stack
7827 size. If the space for the stack is less than 16 bytes aslink trows a
7830 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7831 the 8051. Option 'y' for memory summary output file.
7833 Changes to sdcc (All the changes are marked with 'JCF'):
7835 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7837 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7838 overlaying area for it (uses RegBankUsed[4]).
7840 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7841 bank zero as used by default. By default aslink locates the stack
7842 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7843 the creation of the .mem file. Delegates the allocation of data area
7844 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7845 the begining of the stack area to aslink.
7847 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7848 glue() in SDCCglue.c creates an area for it.

7851 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7852 sdcc/src/pic/glue.c:
7853 introduced atexit() handler for teporay files removal in case of
7854 errors, assertions, ...
7856 2002-08-29 Borut Razem <borut.razem AT siol.net>
7857 * sdcc/support/cpp2/auto-host_vc_in.h:
7858 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7859 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7860 Maybe there is a similar problem with BORLANDC? It should be checked!
7862 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7863 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7864 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7865 was not executed, and the compiler (cl) launched a warning:
7866 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7868 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7869 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7871 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7872 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7874 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7875 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7876 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7877 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7878 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7879 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7880 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7881 - added Release configuration in VS projects
7882 - review of compiler an linker options
7883 - VC .exe files are generated in bin_vc directory, not to interfere
7884 with binaries generated from other projects (cygwin, mingw, bcc ...)
7886 * sdcc/src/yacc.dsp: added
7888 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7889 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7890 and insert the version number definitions from .version
7892 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7894 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7895 added - genarate auto-host.h using auto-host_vc_in.h as template
7898 removed from CVS, generated automatically
7900 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7901 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7903 2002-08-11 Borut Razem <borut.razem AT siol.net>
7904 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7906 2002-08-10 Borut Razem <borut.razem AT siol.net>
7907 * src/SDCCmain.c (main):
7908 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7909 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7910 The consequence was that some temporary files were not removed.
7913 unification of code in functions tempfilename() and tempfile():
7914 function tempnam() is defined in Visual Studio 6.0 and .NET
7916 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7918 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7919 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7920 - removed compiler command line option /WX: Treats all warnings as errors
7921 - update a list of source files, included into the project
7923 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7924 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7925 changed project type to Generic Project so that can be correcly converted to VS.NET project
7927 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7929 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7931 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7933 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7934 added return 0 statements after assert() to make compiler happy
7936 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7937 added newline in the def file to keep MSC compiler satisfied
7939 * sdcc/src/z80/gen.c:
7940 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7941 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7942 - solved MSC error in function aopDump()
7944 * sdcc_vc.h: define PREFIX as "\\sdcc"
7946 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7947 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7995 Added -p option. Allows port dependent processor to be specified.
7998 Initialized the new field char *Processor field to NULL in all ports
8001 Compiler generated registers for interrupt context saving
8002 were not getting allocated.
8004 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8007 Fixed left shift. Will promote the left side of a left shift
8008 if a) left shifting more than size of operand or b) when assigned
8009 to something size > size of left side
8011 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8013 tons of changes. Register allocation has been
8014 rewritten. Added customization for the various PICs. Flow

8121 * sdcc/src/SDCCloop.c:
8122 Previous fix was not good. basic blocks that have "break" or "return" are
8123 not really partof a loop , but live ranges used in these blocks should
8124 be live thru the entire loop, so set partOfLoop but don't add them to
8127 2002-02-21 <johan AT FRIJA>
8129 * src/SDCCcse.c: fixed bug #514308
8131 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8137 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8139 2002-02-10 Karl Bongers <karl AT turbobit.com>
