670 * (Remove2pcodes): after removing register, check to see if it
671 should be removed from local register store/restore in/from stack

811 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
813 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
815 * device/lib/printf_large.c: removed inline assembly for portability and
816 readability. Use printf_fast if speed or size are more important.
817 * src/pic16/gen.c: removed conditions around use of DEBUGpc
818 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
820 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
822 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
823 prevent compiler warning
825 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
827 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
828 moved to level 0 and declared as static. Also they are explicit
829 placed in access bank. This was necessery because some times they
830 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
831 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
832 optimizations. Currently only compare to unsigned char is implemented,
833 * src/pic16/gen.c: added fReturnIdx array,
834 * (struct resolvedIfx) is moved to gen.h and made public,
835 * (struct _G): added sregsAlloc and sregsAllocSet fields,
836 * (aopForSym): added an optimization to directly store in stack of
837 the operand of a SEND iCode,
838 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
839 but as registers instead (AOP_REG) using the fReturnIdx array,
840 * (pic16_freeAsmop): remove the freed register from the
842 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
844 * (pic16_popGetTempRegCond): changed function prototype, now
845 function takes also a bitVector argument v which holds the current
846 set of registers that are allocated for stack access by aopForSym,
847 registers allocated in aopForSym for accessing stack symbols are not
848 any more part of the functions usedRegs field,
849 * (genCall): some times aopOp is called for a stack variable to be
850 send, aopForSym might perform the push, if this is true make sure
851 that genCall doesn't push the variable twice by testing _G.resDirect,
852 * (genFunction): changed testing for unspecified interrupt number
853 from 256 to INTNO_UNSPEC,
854 * modified selection scheme of frame pointer generation. Previously
855 if function did use local registers a frame pointer was generated,
856 now a frame pointer is generated only if function has arguments
857 (that need PLUSW2 register access), or has stack arguments, or the
858 compiler is not instructed to omit the frame pointer,
859 * (genEndFunction): before restoring local registers that were saved
860 in the function preamble, also restore the registers that *might*
861 have been allocated for stack access,
862 * (genRet): removed some old comments,
863 * (genCmp, the active (RN's) version): added a call to the
864 pic16_genCmp_special function to perform the compare with a more
865 robust and optimized way,
866 * (genInline): a feature has been added in inline code generation,
867 which allows a wildcard variable substitution when writing inline
868 assembly. Code is incomplete and experimental therefore undocumented,
869 * (genCast): changed order of aopOp for result and right to allow
870 aopForSym to directly load the result if possible,
871 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
872 perform an optimized compare on some selected special occasions,
873 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
874 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
875 generate an IVT any more,
876 * src/pic16/main.c (pic16_optionsTable): added command line option
878 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
879 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
881 * src/pic16/NOTES: Raphael Neider added in list of active developers
882 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
883 jumptable_end to prevent bug #,
884 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
885 inCond and outCond fields,
886 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
887 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to

1539 Adding support for replacing ljmps with sjmps in jumptables
1540 generated for switch statements. For now you need to set the
1541 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1542 Now 4 algorithms for mcs51 jumptable generation are used:
1543 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1544 addresses loaded pc-relative for up to 112 cases and stack-pushing
1545 target addresses loaded with offset from dptr for up to 256 cases.

1575 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1577 * added libc directory. The current version of LibC contains string
1578 functions, ctype functions and macros and some functions of the
1579 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1580 be extensively tested in the future. Standard disclaimer here.
1581 Library is not automatically build yet. But one can build it by
1582 invoking 'make' inside the libc directory.

1593 * (pic16_storeForReturn): optimized return of 0,
1594 * (genCmp): experimental code for new genCmp which uses PIC18's
1595 special compare&skip instructions. Initial tests fail some times
1596 with variables grater than 1 byte in size, so new code is disabled,
1597 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1599 * (genCast): began a fix to optimize the casting of a bit to another
1600 bit, now assigning a bitfield to another bitfield will fail, sorry,

1609 and 1 for banking instruction,
1610 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1611 caused stop processing pCodes after a inline assembly block,
1612 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1614 registers when it shouldn't,
1615 * src/pic16/ralloc.c (allocReg): add preliminary support for
1616 supporting a limited set of temporary registers,
1618 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4626 loaded with the linker search paths (-L arguments) and the libraries
4627 to be linked with the current source (-l arguments). Changes
4628 currently will affect only the pic16 port.
4629 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4630 include path the port specific paths and port specific libraries,
4631 * gplink command now contains the $3 argument,
4632 * src/pic16/device.h,

4649 Documenting changes from previous commits.
4650 * configure.in (version 1.56),
4651 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4652 when generating output files to configure the pic16 library,
4653 but now I've commented it out, since gputils aren't installed in the
4654 SF compile farm, so library won't compile
4656 * device/lib/Makefile.in (version 1.56): initially I've added in
4657 target 'all' the prerequestive 'model-pic16' so it compiled the
4658 pic16 library, but now I've commented it out for the same reasons
4660 * added targets 'model-pic16' and 'objects-pic16' to compile the
4662 * added target 'port-specific-objects-pic16' to handle the
4663 generated libraries and copy them into the build/ directory
4664 * added target 'clean-intermediate-pic16' to clean intermediate
4665 files into pic16 directory
4666 * in target 'installdirs' added line to create directory pic16 in

4670 added lines to copy all header files to installation path,
4671 * in target 'installdirs' added line create directory for pic16
4672 headers in the installation path

4903 * as/mcs51/lkmain.c: Help about -Y option
4904 * as/mcs51/lkarea.c: Fixed gcc warnings
4906 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4908 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
4910 * support/valdiag/tests/overflow.c: added
4911 * src/SDCCast.c (decorateType),
4912 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4913 LEFT_OP (left shift)
4915 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4917 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4918 (default behaviour).
4920 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4922 A python script to validate compiler diagnostic messages. It can be
4923 used to verify that sdcc complains about bad c source code and
4924 gives a good location of the error.
4925 * support/valdiag/Makefile,
4926 * support/valdiag/valdiag.py,
4927 * support/valdiag/tests/*
4929 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4931 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4932 * src/SDCCsymt.c (newEnumType),
4934 * support/Util/SDCCerr.c,
4935 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
4937 * support/regression/tests/enum.c: added test for enum values that
4938 require at least 2 bytes of storage.
4940 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4942 * src/common.h: added ifndef/define/endif macros
4943 around the header file.
4944 Bug reported from Jesus Calvino-Fraga
4946 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4948 * sdcc.spec: updated
4949 * device/include/Makefile.in: don't install CVS directories
4950 * device/lib/Makefile.in: added removal of CVS directories after install
4951 * doc/Makefile: fixed install, added local_icons
4952 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4953 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4954 * src/ds390/gen.c (genRightShift): fixed bug #870788
4955 * src/SDCCast.c (decorateType): fixed bug #870781
4957 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4959 PIC16 port related changes:
4960 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4961 added variable stackPos,
4963 * gen.c: genCall, assignResultValue: added support for
4964 pushing/retrieving function parameters to/from stack,
4965 genFunction,genEndFunction: setup stack frame for the
4967 genAddrOf: will be changed according to bug 863624
4969 * added files genutils.c and genutils.h which contain gen*
4970 debugged and optimised functions extracted from gen.c
4972 * glue.c: added variable 'externs' which holds extern symbols,
4973 pic16emitRegularMap: is modified to properly handle relocatable
4974 symbols under the new scheme,
4975 pic16createInterruptVect: is modified
4976 pic16printPublics: is modified to emit 'global' assembler directives,
4977 added pic16_printExterns to print extern symbols,
4978 pic16glue: initializes stack/frame pointer in the beginning of
4979 the assembly output. Temporary hack, will be corrected later,
4980 because gplink yet does not support stack and SDCC does not
4981 yet support a type of crt0.o object to create the final binary.
4983 * Removed many lines that contain 8051 legacy code.
4984 * The code is finally placed under a 'code' directive.
4985 * Added port specific options.
4987 * _process_pragma: simplified since now we do not need *special*
4988 include file to define SFR registers. But a separate header
4989 will be needed. This will be developed later.
4990 * _pic16_parseOptions: added, parses port specific options:
4991 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4992 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4993 --preplace-udata-with=
4995 * _pic16_setDefaultOptions: modified to initialize section names,
4996 but hack is temporarly out of order since it needs improvement.
4997 * _pic16_genAssemblerPreamble: configuration words are emitted by
4998 their address instead of their name. This part is incomplete and
4999 supports only the 18Fxx2 devices. Other devices will emit an error
5000 during assembly since they do not contain the same set of config
5002 * _pic16_genIVT: is modified,
5004 * pcode.c: added definitions for some hardware registers that are needed
5006 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5007 All PCI entries are updated. Now LFSR is supported.
5008 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5009 * added pic16_newpCodeOpLit2 to support instructions with
5010 two literal arguments
5011 * pic16_pCode2str: corrected code that emits assembler instructions
5012 with two literal operands and those that have an access bit modifier
5013 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5014 this fixes a bug which caused some labels to be lost, when an
5015 assembler directive was added, i.e. banksel,
5016 * pic16_FixRegisterBanking: improved logic that causes the insertion
5018 * InlineFunction: functions that are called once, are not any more
5019 inlined. This can be a port option in the future,
5021 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5023 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5024 hold the corresponding uninitialized symbols,
5025 * pic16_allocProcessorRegister: registers have explicit marked the
5027 * pic16_allocInternalRegister: registers are explicit marked as
5029 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5030 processing list, so bit registers were lost,
5033 * ralloc.h: added field 'accessBank' and original symbol operand
5034 in register definition,
5035 * removed the field isMapped from register definition,
5037 ** Several functions have been removed from various sources:
5038 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5039 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5040 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5041 pic16_assignRelocatableRegisters
5043 ** others have been introduced:
5044 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5045 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5047 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5049 * support/scripts/inc2h.pl: changed definition of BIT_AT
5050 to emit 'sbit at' instead of 'bit at'. This was a request.
5052 PIC16 port related preliminary changes:
5053 * gen.c: prefixed function popRegFromString with
5054 pic16_ and all references to it corrected
5055 * pcode.c: all pic16_pc_* hardware registers prefixed
5056 with underscore (_),
5057 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5058 * ralloc.c: newReg(): when register is REG_SFR then
5059 set address to rIdx,
5060 pic16_allocProcessorRegister(): marks register wasUsed=0
5061 pic16_writeUsedRegs(): added a call to assign processor
5062 registers via pic16_assignFixedRegisters
5064 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5066 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5067 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5068 variables in unused register banks. Also the SSEG is placed
5069 wherever there is enough space for it, and IDATA can be anywhere
5070 in internal RAM. For now compile using -Wl-Y[stack_size].
5071 The mem file is different for this option as well, since it
5072 makes no sense of talking about DSEG lenght.
5074 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5076 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5077 in certain cases, e.g. when ROM assignment, patch provided
5078 from Albert den Haan.
5080 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5223 * src/mcs51/peephole.def,
5224 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5236 multiply defined with mismatching "at" address.
5238 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5240 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

5319 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5321 * src/SDCCast.c (decorateType): disabled a transformation I added in
5322 revision 1.188 (access to fields of a structure at an absolute address);
5323 it breaks with bitfields, extern declarations, and gcse analysis.
5324 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5325 could be assigned through a pointer, so don't complain.
5326 * src/SDCCast.c (astErrors),
5328 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5965 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5966 support for standard C idiom of memory mapped variables; for
5967 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5968 to xdata int at 0x1234 tempvar = 1.
5969 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5970 provided by Akiya ISHIDA

5986 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5988 Fixed bug #621531 (const & volatile confusion in the type chain).
5989 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
5990 refer to the const or volatile state of the pointer itself.

6081 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6082 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6083 fetching of the pointer
6084 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6085 copied from genNearPointerSet()
6086 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6087 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6088 If they pop r0/r1 they must be called in the opposite order than aopOp().
6089 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6090 (resp. --stack-auto), prepared for --xstack

6101 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6103 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6104 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6105 type for bits was changed. It resulted in bit variables becoming
6106 global, which is not permitted in PIC 14 assembly output.
6108 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6110 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6123 A few small changes that speed up the peephole optimizer.
6127 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6129 Try to make the peephole optimizer smarter by maintaining
6130 an association between the assembly source code and the
6131 iCodes that originated them. Put this information to use
6132 with a new peephole rule condition "notVolatile" so that
6133 the rules can be aggressive yet still safe.
6138 * src/mcs51/peeph.def
6140 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6144 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6145 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6146 if the left or right operand symbols have the accuse flag set.
6148 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6150 Changed the type of the result of the ! (NOT) operator to char;
6151 previously it returned the same type as the source. This allows
6152 us to eliminate all the genFloatNot functions (all of its target
6153 implementations were very buggy) since !float can use the same
6156 * src/SDCCicode.c (ast2iCode): ! returns char

6165 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6166 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6167 during interrupts. Ensure WSAVE is located at a shared bank address.
6168 2. Fixed page selection in some places
6169 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6170 the registers name strings.
6171 4. Fixed "signed / unsigned compare" compiler warnings.
6172 5. The PIC port manages its own allocation of the general purpose
6173 registers, but makes no attempt to reuse them. As a result when
6174 compiling it soon runs out of general purpose registers. Some
6175 additional code was added to the files pcode.c and device.c to walk
6176 through the function call tree and rename the registers so that they
6186 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6187 genPlus() & genMinus() when the result is the same as left or right

6193 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6195 Made bitfield a distinct type from bit so that bitfields
6196 convert as per ANSI C and bits retain their traditional
6197 boolean style behaviour. Implemented bitfield support in
6205 * src/ds390/gen.c: bit v bitfield split
6206 * src/z80/gen.c: New support for bitfields
6207 * support/regression/tests/bitfields.c: reenabled z80,
6210 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6212 Rules 246.x, 247.x relate to bitfields, the others speed up
6213 access to xdata mapped I/O devices.
6215 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6217 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6219 Cleaned up genPackBits and genUnpackBits and added two helper
6220 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6221 for literal assignments in genPackBits (thanks to Frieder for
6227 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6229 Fixed bug #748310 (pointer to function type mishandled when the
6230 function name is omitted). Also fixed a SIGSEGV when a function
6231 attribute (reentrant, etc) is used on a non-function or on a
6232 function but misplaced before the parameter list.
6234 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6236 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6237 * support/Util/SDCCerr.h,
6238 * support/Util/SDCCerr.c: Added func attr misuse error msg
6240 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6242 Fixed bug #787649 by anonymous
6243 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6259 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6261 Made the constant following the "interrupt" keyword optional. If
6262 omitted, the function will not automatically be given an entry
6263 in the interrupt vector table (similar to #pragma NOIV, but
6264 less syntacticly kludgy). The interrupt number is also now
6265 range checked. Also fixed a bug in the high order bit example

6276 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6278 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6279 * src/SDCCicode.c (operandOperation): rewritten some ops
6280 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6281 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6283 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6284 be re-activated by defining REDUCE_LITERALS)
6285 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6286 unsigned, but are signed by default
6287 * src/SDCCval.c (constVal): rearranged
6288 * src/SDCCval.c (valMod): preliminary fix
6289 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6331 constants are unsigned; added recognition of "u" flag for unsigned
6332 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6333 * src/SDCCval.c (valDiv, valMod): fixed signdness
6334 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6335 signedness of modulo, left and right shift

6795 added if/endif conditional macros to remove options help
6796 messages from optionsTable when a port is not configured, added
6797 support for the PIc16 port in the ports table, when executing
6798 the compiler with no port specified on command line, a default
6799 port is selected with the new macro DEFAULT_PORT which is
6800 defined in port.h, in setDefaultOptions() linkOptions is removed
6801 from initialization assignment, since now it is a set,
6802 parseCmdLine uses setParseWithComma for linkOptions, in
6803 linkEdit() linkOptions are accessed with new function indexSet()
6804 which returns the i'th item of a set variable. See SDCCset.c, in
6805 linkEdit() when calling buildCmdLine(), added linkOptions as
6806 last argument. Now users can pass arguments to gplink via the
6807 -Wl option, main() uses pic16glue() to glue up pic16 programs

6821 gpasm complaining and test the linkage with gplink, _linkCmd and
6822 _asmCmd changed to be more gplink and gpasm friendly
6823 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6824 produced an error when parsed, peep rule 12 is added to utilize
6825 movff, but it is commented out since the pCode does not support
6826 yet a command with 2 address arguments
6828 2003-05-18 <johan AT balder>
6830 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6857 2003-05-11 Borut Razem <borut.razem AT siol.net>
6859 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7845 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
7846 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
7848 2003-01-07 <johan AT balder>
7850 * src/SDCCast.c (decorateType): fixed bug #600035
7852 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7853 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

7857 * src/pic/ralloc.c: outcommented unused variable to remove warnings
7859 2003-01-06 <karl AT turbobit.com>
7860 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
7863 2003-01-06 <johan AT balder>
7865 * src/SDCCicode.c: fixed array add
7867 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7868 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7869 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7871 2003-01-04 <johan AT balder>
7873 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7875 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7876 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7878 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7879 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7880 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7882 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7883 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7885 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7886 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7888 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7889 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7891 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7893 * in \sdcc\as\mcs51\ changed these files in order to create an
7894 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7895 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7896 following files to include the previous two files: aslink.dsp,
7897 Makefile.aslink, Makefile.bcc, and Makefile.in.
7899 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7900 .adb instead of .cdb
7902 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7904 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7905 value from option --iram-size.
7907 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7909 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7912 2002-09-18 <wiml AT hhhh.org>
7914 * SDCClrange.h: exposed setFromRange() and setToRange()
7915 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7916 packRegsForAccUse() (bug 542397)
7917 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7918 multiple times and emitting the fetch operations more than once
7919 added aopGetUsesAcc() function to allow binary operators to
7920 fetch their operands in the correct order; made genMinus() emit
7921 compact code for X = LITERAL - Y
7923 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7924 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7925 sprintf() in line 1267.
7927 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7928 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7931 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7932 Changes to aslink (All the changes are marked with 'JCF'):
7934 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7937 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7938 area BSEG. Also moves, if possible, the DATA area down into the internal
7939 ram so more space is available.
7941 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7944 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7945 not bytes. Function summary() which creates a memory usage summary
7946 file with extension .mem. Reports of overlaping stack and small stack
7947 size. If the space for the stack is less than 16 bytes aslink trows a
7950 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7951 the 8051. Option 'y' for memory summary output file.
7953 Changes to sdcc (All the changes are marked with 'JCF'):
7955 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7957 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7958 overlaying area for it (uses RegBankUsed[4]).
7960 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7961 bank zero as used by default. By default aslink locates the stack
7962 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7963 the creation of the .mem file. Delegates the allocation of data area
7964 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7965 the begining of the stack area to aslink.
7967 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7968 glue() in SDCCglue.c creates an area for it.
7970 2002-09-03 Borut Razem <borut.razem AT siol.net>
7971 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7972 sdcc/src/pic/glue.c:
7973 introduced atexit() handler for teporay files removal in case of
7974 errors, assertions, ...
7976 2002-08-29 Borut Razem <borut.razem AT siol.net>
7977 * sdcc/support/cpp2/auto-host_vc_in.h:
7978 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7979 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7980 Maybe there is a similar problem with BORLANDC? It should be checked!
7982 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7983 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7984 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7985 was not executed, and the compiler (cl) launched a warning:
7986 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7988 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7989 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7991 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7992 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7994 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7995 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7996 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7997 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7998 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7999 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8000 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8001 - added Release configuration in VS projects
8002 - review of compiler an linker options
8003 - VC .exe files are generated in bin_vc directory, not to interfere
8004 with binaries generated from other projects (cygwin, mingw, bcc ...)
8006 * sdcc/src/yacc.dsp: added
8008 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8009 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8010 and insert the version number definitions from .version
8012 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8014 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8015 added - genarate auto-host.h using auto-host_vc_in.h as template
8018 removed from CVS, generated automatically
8020 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8021 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8023 2002-08-11 Borut Razem <borut.razem AT siol.net>
8024 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8026 2002-08-10 Borut Razem <borut.razem AT siol.net>
8027 * src/SDCCmain.c (main):
8028 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8029 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8030 The consequence was that some temporary files were not removed.
8033 unification of code in functions tempfilename() and tempfile():
8034 function tempnam() is defined in Visual Studio 6.0 and .NET
8036 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8038 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8039 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8040 - removed compiler command line option /WX: Treats all warnings as errors
8041 - update a list of source files, included into the project
8043 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8044 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8045 changed project type to Generic Project so that can be correcly converted to VS.NET project
8047 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8049 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8051 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8053 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8054 added return 0 statements after assert() to make compiler happy
8056 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8057 added newline in the def file to keep MSC compiler satisfied
8059 * sdcc/src/z80/gen.c:
8060 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8061 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8062 - solved MSC error in function aopDump()
8064 * sdcc_vc.h: define PREFIX as "\\sdcc"
8066 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8067 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8069 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8070 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8071 - Rewrote the register banking algorithm.
8072 - Added pCode live-range analysis to registers (for now, only non-used and
8073 singly-used registers optimized away)
8075 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8077 * 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.
8079 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8080 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

8102 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8104 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8106 2002-03-28 Johan Knol <johan AT balder>
8108 * src/SDCCval.c: fixed bug #532436
8110 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8112 Added "char *Processor" field to the port structure.
8115 Added -p option. Allows port dependent processor to be specified.
8118 Initialized the new field char *Processor field to NULL in all ports
8121 Compiler generated registers for interrupt context saving
8122 were not getting allocated.
8124 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8127 Fixed left shift. Will promote the left side of a left shift
8128 if a) left shifting more than size of operand or b) when assigned
8129 to something size > size of left side
8131 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8133 tons of changes. Register allocation has been
8134 rewritten. Added customization for the various PICs. Flow
8135 analysis is restructured. ...
8141 Added. device.c is a PIC port hack to accomodate variations
8144 2002-03-13 Michael Hope <michaelh AT vroom>
8146 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8148 2002-03-04 johanknol <johanknol AT manik>
8150 * /src/SDCCval.c: fixed
8152 const unsigned char arr[][2] = { { 0, 1 } };
8153 t18.c:1: error: Initializer element is not constant
8155 2002-03-04 bela <bela AT manik>
8157 * /device/include/mcs51reg.h:
8158 ds89c420 register definition update
8160 2002-03-03 <johan AT FRIJA>

8239 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8241 * sdcc/src/SDCCloop.c:
8242 Previous fix was not good. basic blocks that have "break" or "return" are
8243 not really partof a loop , but live ranges used in these blocks should
8244 be live thru the entire loop, so set partOfLoop but don't add them to
8247 2002-02-21 <johan AT FRIJA>
8249 * src/SDCCcse.c: fixed bug #514308
8251 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8254 Fixed BUG #519583. If a conditional block ended in a return/break
8255 statement inside a loop, it was not being considered part of the loop.
8257 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8259 2002-02-10 Karl Bongers <karl AT turbobit.com>
8262 Fixed up SDCDB debugger somewhat. Updated debugger/README
8263 with lots of comments and notes.
8265 * device/examples/test2.c:
8266 Fix bug, "red" variable not being initialized(compiler complained).
8268 * device/examples/Makefile, examples/test3.c:
8269 Add Makefile in device/examples folder, compiles test3.c
8270 for use as a multiple module SDCDB test case.
8272 * sim/ucsim/cmd.src/cmdset.cc:
8273 Took out debug printfs in ucsim "next" command.
8276 Karl and Johan start ucsim XA support. Most dissassembly working,
8277 about 75% emulation done(plenty of work remaining).
8279 * sim/ucsim/z80.src:
8280 Add Z80 support to ucsim, add test-ucz80 regression test,
8281 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8282 Notice z80 compiler fails on examples/test3.c/crc code.
8284 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
8286 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
8287 Added support for --parms-in-bank1
8289 * src/ds390/peeph.def:
8290 added a few more peephole optimzations
8293 1) added __builtin_inp & __builtin_outp used to read in data of given length
8294 from a memory mapped port
8295 2) added __builtin_memcmp
8296 3) added __builtin_swapw swap bytes of a short
8298 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
8299 1) handle multiple send & receives from register bank1
8300 2) ralloc can now allocate DPTR1 to some liveRanges
8302 * src/SDCCsymt.c, src/SDCCsymt.h:
8303 changes to handle multiple sends & receives
8306 added some pointer arithmetic optimization
8309 added some pointer arithmetic optimizations but not stable yet so not
8310 called from anywhere (will get this working shortly)
8312 * src/SDCCopt.c: fixed for multiple sends & receives
8315 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8316 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8317 set preprocessor defines (depending on options)
8319 * src/SDCCicode.c, src/SDCCicode.h:
8320 changes made to handle multiple sends & receives
8323 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
8325 * src/SDCCcse.c, src/SDCCcse.h:
8326 added function findbackward def (to be used in upcoming optimization)
