756 2005-03-20 Borut Razem <borut.razem AT siol.net>
758 * support/scripts/inc2h.pl: WIN32 port

784 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
786 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
788 * device/lib/printf_large.c: removed inline assembly for portability and
789 readability. Use printf_fast if speed or size are more important.
790 * src/pic16/gen.c: removed conditions around use of DEBUGpc
791 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
793 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
795 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
796 prevent compiler warning
798 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
800 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
801 moved to level 0 and declared as static. Also they are explicit
802 placed in access bank. This was necessery because some times they
803 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
804 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
805 optimizations. Currently only compare to unsigned char is implemented,
806 * src/pic16/gen.c: added fReturnIdx array,
807 * (struct resolvedIfx) is moved to gen.h and made public,
808 * (struct _G): added sregsAlloc and sregsAllocSet fields,
809 * (aopForSym): added an optimization to directly store in stack of
810 the operand of a SEND iCode,
811 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
812 but as registers instead (AOP_REG) using the fReturnIdx array,
813 * (pic16_freeAsmop): remove the freed register from the
815 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
817 * (pic16_popGetTempRegCond): changed function prototype, now
818 function takes also a bitVector argument v which holds the current
819 set of registers that are allocated for stack access by aopForSym,
820 registers allocated in aopForSym for accessing stack symbols are not
821 any more part of the functions usedRegs field,
822 * (genCall): some times aopOp is called for a stack variable to be
823 send, aopForSym might perform the push, if this is true make sure
824 that genCall doesn't push the variable twice by testing _G.resDirect,
825 * (genFunction): changed testing for unspecified interrupt number
826 from 256 to INTNO_UNSPEC,
827 * modified selection scheme of frame pointer generation. Previously
828 if function did use local registers a frame pointer was generated,
829 now a frame pointer is generated only if function has arguments
830 (that need PLUSW2 register access), or has stack arguments, or the
831 compiler is not instructed to omit the frame pointer,
832 * (genEndFunction): before restoring local registers that were saved
833 in the function preamble, also restore the registers that *might*
834 have been allocated for stack access,
835 * (genRet): removed some old comments,
836 * (genCmp, the active (RN's) version): added a call to the
837 pic16_genCmp_special function to perform the compare with a more
838 robust and optimized way,
839 * (genInline): a feature has been added in inline code generation,
840 which allows a wildcard variable substitution when writing inline
841 assembly. Code is incomplete and experimental therefore undocumented,
842 * (genCast): changed order of aopOp for result and right to allow
843 aopForSym to directly load the result if possible,
844 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
845 perform an optimized compare on some selected special occasions,
846 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
847 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
848 generate an IVT any more,
849 * src/pic16/main.c (pic16_optionsTable): added command line option
851 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
852 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
854 * src/pic16/NOTES: Raphael Neider added in list of active developers
855 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
856 jumptable_end to prevent bug #,
857 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
858 inCond and outCond fields,
859 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
860 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
861 turn off register spilling,
862 * (packRegsForOneUse): synced with other ports' versions although it
863 is not used currently,
864 * (pic16_packRegisters): added an optimization while reading
865 structure bitfields, some registers may be saved (malloc code is
866 decreased by 80 bytes)
868 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
870 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
871 left is a bitfield, if yes, then don't optimize assignment. Perhaps
872 this can be optimized more?
874 2005-03-10 Raphael Neider <rneider AT web.de>
876 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
877 genNearPointerGet): (hopefully) fixed access to bitfields via
878 pointers (p->bitN = x; and x = p->bitN; failed)
880 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
882 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
884 2005-03-09 Raphael Neider <rneider AT web.de>
886 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
888 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
890 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC

1512 Adding support for replacing ljmps with sjmps in jumptables
1513 generated for switch statements. For now you need to set the
1514 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1515 Now 4 algorithms for mcs51 jumptable generation are used:
1516 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1517 addresses loaded pc-relative for up to 112 cases and stack-pushing
1518 target addresses loaded with offset from dptr for up to 256 cases.

1548 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1550 * added libc directory. The current version of LibC contains string
1551 functions, ctype functions and macros and some functions of the
1552 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1553 be extensively tested in the future. Standard disclaimer here.
1554 Library is not automatically build yet. But one can build it by
1555 invoking 'make' inside the libc directory.

1565 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1566 * (pic16_storeForReturn): optimized return of 0,
1567 * (genCmp): experimental code for new genCmp which uses PIC18's
1568 special compare&skip instructions. Initial tests fail some times
1569 with variables grater than 1 byte in size, so new code is disabled,
1570 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1572 * (genCast): began a fix to optimize the casting of a bit to another
1573 bit, now assigning a bitfield to another bitfield will fail, sorry,
1574 * src/pic16/main.c: disabled the use of lr-support feature,
1575 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1581 * (isBankInstruction): modified to return 0 for no banking instruction,
1582 and 1 for banking instruction,
1583 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1584 caused stop processing pCodes after a inline assembly block,
1585 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1586 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1587 registers when it shouldn't,
1588 * src/pic16/ralloc.c (allocReg): add preliminary support for
1589 supporting a limited set of temporary registers,
1591 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1593 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1594 genDataPointerSet): ensure assignments always copy in MSB to LSB
1596 (loadRegFromAop): recognize CLRH optimization,
1597 (genFunction): optimize RECEIVE iCodes in reentrant functions
1599 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1601 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4599 loaded with the linker search paths (-L arguments) and the libraries
4600 to be linked with the current source (-l arguments). Changes
4601 currently will affect only the pic16 port.
4602 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4603 include path the port specific paths and port specific libraries,
4604 * gplink command now contains the $3 argument,
4605 * src/pic16/device.h,

4622 Documenting changes from previous commits.
4623 * configure.in (version 1.56),
4624 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4625 when generating output files to configure the pic16 library,
4626 but now I've commented it out, since gputils aren't installed in the
4627 SF compile farm, so library won't compile
4629 * device/lib/Makefile.in (version 1.56): initially I've added in
4630 target 'all' the prerequestive 'model-pic16' so it compiled the
4631 pic16 library, but now I've commented it out for the same reasons
4633 * added targets 'model-pic16' and 'objects-pic16' to compile the
4635 * added target 'port-specific-objects-pic16' to handle the
4636 generated libraries and copy them into the build/ directory
4637 * added target 'clean-intermediate-pic16' to clean intermediate
4638 files into pic16 directory
4639 * in target 'installdirs' added line to create directory pic16 in

4905 * src/SDCCsymt.c (newEnumType),
4907 * support/Util/SDCCerr.c,
4908 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
4910 * support/regression/tests/enum.c: added test for enum values that
4911 require at least 2 bytes of storage.
4913 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4915 * src/common.h: added ifndef/define/endif macros
4916 around the header file.
4917 Bug reported from Jesus Calvino-Fraga
4919 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4921 * sdcc.spec: updated
4922 * device/include/Makefile.in: don't install CVS directories
4923 * device/lib/Makefile.in: added removal of CVS directories after install
4924 * doc/Makefile: fixed install, added local_icons
4925 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4926 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4927 * src/ds390/gen.c (genRightShift): fixed bug #870788
4928 * src/SDCCast.c (decorateType): fixed bug #870781
4930 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4932 PIC16 port related changes:
4933 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4934 added variable stackPos,
4936 * gen.c: genCall, assignResultValue: added support for
4937 pushing/retrieving function parameters to/from stack,
4938 genFunction,genEndFunction: setup stack frame for the
4940 genAddrOf: will be changed according to bug 863624
4942 * added files genutils.c and genutils.h which contain gen*
4943 debugged and optimised functions extracted from gen.c
4945 * glue.c: added variable 'externs' which holds extern symbols,
4946 pic16emitRegularMap: is modified to properly handle relocatable
4947 symbols under the new scheme,
4948 pic16createInterruptVect: is modified
4949 pic16printPublics: is modified to emit 'global' assembler directives,
4950 added pic16_printExterns to print extern symbols,
4951 pic16glue: initializes stack/frame pointer in the beginning of
4952 the assembly output. Temporary hack, will be corrected later,
4953 because gplink yet does not support stack and SDCC does not
4954 yet support a type of crt0.o object to create the final binary.
4956 * Removed many lines that contain 8051 legacy code.
4957 * The code is finally placed under a 'code' directive.
4958 * Added port specific options.
4960 * _process_pragma: simplified since now we do not need *special*
4961 include file to define SFR registers. But a separate header
4962 will be needed. This will be developed later.
4963 * _pic16_parseOptions: added, parses port specific options:
4964 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4965 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4966 --preplace-udata-with=
4968 * _pic16_setDefaultOptions: modified to initialize section names,
4969 but hack is temporarly out of order since it needs improvement.
4970 * _pic16_genAssemblerPreamble: configuration words are emitted by
4971 their address instead of their name. This part is incomplete and
4972 supports only the 18Fxx2 devices. Other devices will emit an error
4973 during assembly since they do not contain the same set of config
4975 * _pic16_genIVT: is modified,
4977 * pcode.c: added definitions for some hardware registers that are needed
4979 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4980 All PCI entries are updated. Now LFSR is supported.
4981 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4982 * added pic16_newpCodeOpLit2 to support instructions with
4983 two literal arguments
4984 * pic16_pCode2str: corrected code that emits assembler instructions
4985 with two literal operands and those that have an access bit modifier
4986 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4987 this fixes a bug which caused some labels to be lost, when an
4988 assembler directive was added, i.e. banksel,
4989 * pic16_FixRegisterBanking: improved logic that causes the insertion
4991 * InlineFunction: functions that are called once, are not any more
4992 inlined. This can be a port option in the future,
4994 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4996 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4997 hold the corresponding uninitialized symbols,
4998 * pic16_allocProcessorRegister: registers have explicit marked the
5000 * pic16_allocInternalRegister: registers are explicit marked as
5002 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5003 processing list, so bit registers were lost,
5006 * ralloc.h: added field 'accessBank' and original symbol operand
5007 in register definition,
5008 * removed the field isMapped from register definition,
5010 ** Several functions have been removed from various sources:
5011 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5012 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5013 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5014 pic16_assignRelocatableRegisters
5016 ** others have been introduced:
5017 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5018 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5020 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5022 * support/scripts/inc2h.pl: changed definition of BIT_AT
5023 to emit 'sbit at' instead of 'bit at'. This was a request.
5025 PIC16 port related preliminary changes:
5026 * gen.c: prefixed function popRegFromString with
5027 pic16_ and all references to it corrected
5028 * pcode.c: all pic16_pc_* hardware registers prefixed
5029 with underscore (_),
5030 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5031 * ralloc.c: newReg(): when register is REG_SFR then
5032 set address to rIdx,
5033 pic16_allocProcessorRegister(): marks register wasUsed=0
5034 pic16_writeUsedRegs(): added a call to assign processor
5035 registers via pic16_assignFixedRegisters
5037 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5039 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5040 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5041 variables in unused register banks. Also the SSEG is placed
5042 wherever there is enough space for it, and IDATA can be anywhere
5043 in internal RAM. For now compile using -Wl-Y[stack_size].
5044 The mem file is different for this option as well, since it
5045 makes no sense of talking about DSEG lenght.
5047 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5049 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5050 in certain cases, e.g. when ROM assignment, patch provided
5051 from Albert den Haan.

5292 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5294 * src/SDCCast.c (decorateType): disabled a transformation I added in
5295 revision 1.188 (access to fields of a structure at an absolute address);
5296 it breaks with bitfields, extern declarations, and gcse analysis.
5297 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5298 could be assigned through a pointer, so don't complain.
5299 * src/SDCCast.c (astErrors),
5301 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5939 support for standard C idiom of memory mapped variables; for
5940 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5941 to xdata int at 0x1234 tempvar = 1.
5942 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5943 provided by Akiya ISHIDA

5959 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5961 Fixed bug #621531 (const & volatile confusion in the type chain).
5962 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
5963 refer to the const or volatile state of the pointer itself.

6054 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6055 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6056 fetching of the pointer
6057 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6058 copied from genNearPointerSet()
6059 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6060 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6074 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6076 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6077 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6078 type for bits was changed. It resulted in bit variables becoming
6079 global, which is not permitted in PIC 14 assembly output.
6081 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6083 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6096 A few small changes that speed up the peephole optimizer.
6100 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6102 Try to make the peephole optimizer smarter by maintaining
6103 an association between the assembly source code and the
6104 iCodes that originated them. Put this information to use
6105 with a new peephole rule condition "notVolatile" so that
6106 the rules can be aggressive yet still safe.
6111 * src/mcs51/peeph.def
6113 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6117 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6118 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6119 if the left or right operand symbols have the accuse flag set.
6121 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6123 Changed the type of the result of the ! (NOT) operator to char;
6124 previously it returned the same type as the source. This allows
6125 us to eliminate all the genFloatNot functions (all of its target
6126 implementations were very buggy) since !float can use the same
6129 * src/SDCCicode.c (ast2iCode): ! returns char

6138 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6139 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6140 during interrupts. Ensure WSAVE is located at a shared bank address.
6141 2. Fixed page selection in some places
6142 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6143 the registers name strings.
6144 4. Fixed "signed / unsigned compare" compiler warnings.
6145 5. The PIC port manages its own allocation of the general purpose
6146 registers, but makes no attempt to reuse them. As a result when
6147 compiling it soon runs out of general purpose registers. Some
6148 additional code was added to the files pcode.c and device.c to walk
6149 through the function call tree and rename the registers so that they
6159 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6160 genPlus() & genMinus() when the result is the same as left or right
6162 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6166 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6168 Made bitfield a distinct type from bit so that bitfields
6169 convert as per ANSI C and bits retain their traditional
6170 boolean style behaviour. Implemented bitfield support in
6178 * src/ds390/gen.c: bit v bitfield split
6179 * src/z80/gen.c: New support for bitfields
6180 * support/regression/tests/bitfields.c: reenabled z80,
6183 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6185 Rules 246.x, 247.x relate to bitfields, the others speed up
6186 access to xdata mapped I/O devices.
6188 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6190 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6192 Cleaned up genPackBits and genUnpackBits and added two helper
6193 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6194 for literal assignments in genPackBits (thanks to Frieder for
6200 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6202 Fixed bug #748310 (pointer to function type mishandled when the
6203 function name is omitted). Also fixed a SIGSEGV when a function
6204 attribute (reentrant, etc) is used on a non-function or on a
6205 function but misplaced before the parameter list.
6207 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6209 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6210 * support/Util/SDCCerr.h,
6211 * support/Util/SDCCerr.c: Added func attr misuse error msg
6213 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6215 Fixed bug #787649 by anonymous
6216 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6232 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6234 Made the constant following the "interrupt" keyword optional. If
6235 omitted, the function will not automatically be given an entry
6236 in the interrupt vector table (similar to #pragma NOIV, but
6237 less syntacticly kludgy). The interrupt number is also now
6238 range checked. Also fixed a bug in the high order bit example

6246 * support/Util/SDCCerr.h
6249 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6251 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6252 * src/SDCCicode.c (operandOperation): rewritten some ops
6253 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6254 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6256 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6257 be re-activated by defining REDUCE_LITERALS)
6258 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6259 unsigned, but are signed by default
6260 * src/SDCCval.c (constVal): rearranged
6261 * src/SDCCval.c (valMod): preliminary fix
6262 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6304 constants are unsigned; added recognition of "u" flag for unsigned
6305 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6306 * src/SDCCval.c (valDiv, valMod): fixed signdness
6307 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6308 signedness of modulo, left and right shift

6768 added if/endif conditional macros to remove options help
6769 messages from optionsTable when a port is not configured, added
6770 support for the PIc16 port in the ports table, when executing
6771 the compiler with no port specified on command line, a default
6772 port is selected with the new macro DEFAULT_PORT which is
6773 defined in port.h, in setDefaultOptions() linkOptions is removed
6774 from initialization assignment, since now it is a set,
6775 parseCmdLine uses setParseWithComma for linkOptions, in
6776 linkEdit() linkOptions are accessed with new function indexSet()
6777 which returns the i'th item of a set variable. See SDCCset.c, in
6778 linkEdit() when calling buildCmdLine(), added linkOptions as
6779 last argument. Now users can pass arguments to gplink via the
6780 -Wl option, main() uses pic16glue() to glue up pic16 programs

6794 gpasm complaining and test the linkage with gplink, _linkCmd and
6795 _asmCmd changed to be more gplink and gpasm friendly
6796 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6797 produced an error when parsed, peep rule 12 is added to utilize
6798 movff, but it is commented out since the pCode does not support
6799 yet a command with 2 address arguments
6801 2003-05-18 <johan AT balder>
6803 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6830 2003-05-11 Borut Razem <borut.razem AT siol.net>
6832 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7832 2003-01-06 <karl AT turbobit.com>
7833 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
7836 2003-01-06 <johan AT balder>
7838 * src/SDCCicode.c: fixed array add
7840 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7841 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7842 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7844 2003-01-04 <johan AT balder>
7846 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7848 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7849 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7851 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7852 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7853 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7855 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7856 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7858 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7859 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7861 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7862 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7864 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7866 * in \sdcc\as\mcs51\ changed these files in order to create an
7867 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7868 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7869 following files to include the previous two files: aslink.dsp,
7870 Makefile.aslink, Makefile.bcc, and Makefile.in.
7872 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7873 .adb instead of .cdb
7875 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7877 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7878 value from option --iram-size.
7880 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7882 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7885 2002-09-18 <wiml AT hhhh.org>
7887 * SDCClrange.h: exposed setFromRange() and setToRange()
7888 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7889 packRegsForAccUse() (bug 542397)
7890 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7891 multiple times and emitting the fetch operations more than once
7892 added aopGetUsesAcc() function to allow binary operators to
7893 fetch their operands in the correct order; made genMinus() emit
7894 compact code for X = LITERAL - Y
7896 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7897 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7898 sprintf() in line 1267.
7900 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7901 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7904 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7905 Changes to aslink (All the changes are marked with 'JCF'):
7907 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7910 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7911 area BSEG. Also moves, if possible, the DATA area down into the internal
7912 ram so more space is available.
7914 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7917 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7918 not bytes. Function summary() which creates a memory usage summary
7919 file with extension .mem. Reports of overlaping stack and small stack
7920 size. If the space for the stack is less than 16 bytes aslink trows a
7923 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7924 the 8051. Option 'y' for memory summary output file.
7926 Changes to sdcc (All the changes are marked with 'JCF'):
7928 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7930 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7931 overlaying area for it (uses RegBankUsed[4]).
7933 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7934 bank zero as used by default. By default aslink locates the stack
7935 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7936 the creation of the .mem file. Delegates the allocation of data area
7937 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7938 the begining of the stack area to aslink.
7940 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7941 glue() in SDCCglue.c creates an area for it.
7943 2002-09-03 Borut Razem <borut.razem AT siol.net>
7944 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7945 sdcc/src/pic/glue.c:
7946 introduced atexit() handler for teporay files removal in case of
7947 errors, assertions, ...
7949 2002-08-29 Borut Razem <borut.razem AT siol.net>
7950 * sdcc/support/cpp2/auto-host_vc_in.h:
7951 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7952 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7953 Maybe there is a similar problem with BORLANDC? It should be checked!
7955 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7956 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7957 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7958 was not executed, and the compiler (cl) launched a warning:
7959 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7961 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7962 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7964 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7965 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7967 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7968 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7969 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7970 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7971 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7972 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7973 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7974 - added Release configuration in VS projects
7975 - review of compiler an linker options
7976 - VC .exe files are generated in bin_vc directory, not to interfere
7977 with binaries generated from other projects (cygwin, mingw, bcc ...)
7979 * sdcc/src/yacc.dsp: added
7981 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7982 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7983 and insert the version number definitions from .version
7985 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7987 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7988 added - genarate auto-host.h using auto-host_vc_in.h as template
7991 removed from CVS, generated automatically
7993 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7994 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7996 2002-08-11 Borut Razem <borut.razem AT siol.net>
7997 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7999 2002-08-10 Borut Razem <borut.razem AT siol.net>
8000 * src/SDCCmain.c (main):
8001 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8002 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8003 The consequence was that some temporary files were not removed.
8006 unification of code in functions tempfilename() and tempfile():
8007 function tempnam() is defined in Visual Studio 6.0 and .NET
8009 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8011 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8012 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8013 - removed compiler command line option /WX: Treats all warnings as errors
8014 - update a list of source files, included into the project
8016 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8017 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8018 changed project type to Generic Project so that can be correcly converted to VS.NET project
8020 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8022 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8024 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8026 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8027 added return 0 statements after assert() to make compiler happy
8029 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8030 added newline in the def file to keep MSC compiler satisfied
8032 * sdcc/src/z80/gen.c:
8033 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8034 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8035 - solved MSC error in function aopDump()
8037 * sdcc_vc.h: define PREFIX as "\\sdcc"
8039 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8040 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8043 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8044 - Rewrote the register banking algorithm.
8045 - Added pCode live-range analysis to registers (for now, only non-used and
8046 singly-used registers optimized away)
8048 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8050 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

8077 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8079 2002-03-28 Johan Knol <johan AT balder>
8081 * src/SDCCval.c: fixed bug #532436
8083 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8085 Added "char *Processor" field to the port structure.
8088 Added -p option. Allows port dependent processor to be specified.
8091 Initialized the new field char *Processor field to NULL in all ports
8094 Compiler generated registers for interrupt context saving
8095 were not getting allocated.
8097 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8100 Fixed left shift. Will promote the left side of a left shift
8101 if a) left shifting more than size of operand or b) when assigned
8102 to something size > size of left side
8104 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8106 tons of changes. Register allocation has been
8107 rewritten. Added customization for the various PICs. Flow
8108 analysis is restructured. ...
8114 Added. device.c is a PIC port hack to accomodate variations
8117 2002-03-13 Michael Hope <michaelh AT vroom>
8119 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8121 2002-03-04 johanknol <johanknol AT manik>

8125 const unsigned char arr[][2] = { { 0, 1 } };
8126 t18.c:1: error: Initializer element is not constant
8128 2002-03-04 bela <bela AT manik>
8130 * /device/include/mcs51reg.h:
8131 ds89c420 register definition update
8133 2002-03-03 <johan AT FRIJA>

8212 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8214 * sdcc/src/SDCCloop.c:
8215 Previous fix was not good. basic blocks that have "break" or "return" are
8216 not really partof a loop , but live ranges used in these blocks should
8217 be live thru the entire loop, so set partOfLoop but don't add them to
8220 2002-02-21 <johan AT FRIJA>
8222 * src/SDCCcse.c: fixed bug #514308
8224 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8227 Fixed BUG #519583. If a conditional block ended in a return/break
8228 statement inside a loop, it was not being considered part of the loop.
8230 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8232 2002-02-10 Karl Bongers <karl AT turbobit.com>
8235 Fixed up SDCDB debugger somewhat. Updated debugger/README
8236 with lots of comments and notes.
8238 * device/examples/test2.c:
8239 Fix bug, "red" variable not being initialized(compiler complained).
8241 * device/examples/Makefile, examples/test3.c:
8242 Add Makefile in device/examples folder, compiles test3.c
8243 for use as a multiple module SDCDB test case.
8245 * sim/ucsim/cmd.src/cmdset.cc:
8246 Took out debug printfs in ucsim "next" command.
8249 Karl and Johan start ucsim XA support. Most dissassembly working,
8250 about 75% emulation done(plenty of work remaining).
8252 * sim/ucsim/z80.src:
8253 Add Z80 support to ucsim, add test-ucz80 regression test,
8254 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8255 Notice z80 compiler fails on examples/test3.c/crc code.

8269 3) added __builtin_swapw swap bytes of a short
8271 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
8272 1) handle multiple send & receives from register bank1
8273 2) ralloc can now allocate DPTR1 to some liveRanges
8275 * src/SDCCsymt.c, src/SDCCsymt.h:
8276 changes to handle multiple sends & receives
8279 added some pointer arithmetic optimization
8282 added some pointer arithmetic optimizations but not stable yet so not
8283 called from anywhere (will get this working shortly)
8285 * src/SDCCopt.c: fixed for multiple sends & receives
8288 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8289 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8290 set preprocessor defines (depending on options)
8292 * src/SDCCicode.c, src/SDCCicode.h:
8293 changes made to handle multiple sends & receives
8296 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
