750 2005-03-20 Borut Razem <borut.razem AT siol.net>
752 * support/scripts/inc2h.pl: WIN32 port

778 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
780 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
782 * device/lib/printf_large.c: removed inline assembly for portability and
783 readability. Use printf_fast if speed or size are more important.
784 * src/pic16/gen.c: removed conditions around use of DEBUGpc
785 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
787 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
789 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
790 prevent compiler warning
792 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
794 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
795 moved to level 0 and declared as static. Also they are explicit
796 placed in access bank. This was necessery because some times they
797 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
798 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
799 optimizations. Currently only compare to unsigned char is implemented,
800 * src/pic16/gen.c: added fReturnIdx array,
801 * (struct resolvedIfx) is moved to gen.h and made public,
802 * (struct _G): added sregsAlloc and sregsAllocSet fields,
803 * (aopForSym): added an optimization to directly store in stack of
804 the operand of a SEND iCode,
805 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
806 but as registers instead (AOP_REG) using the fReturnIdx array,
807 * (pic16_freeAsmop): remove the freed register from the
809 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
811 * (pic16_popGetTempRegCond): changed function prototype, now
812 function takes also a bitVector argument v which holds the current
813 set of registers that are allocated for stack access by aopForSym,
814 registers allocated in aopForSym for accessing stack symbols are not
815 any more part of the functions usedRegs field,
816 * (genCall): some times aopOp is called for a stack variable to be
817 send, aopForSym might perform the push, if this is true make sure
818 that genCall doesn't push the variable twice by testing _G.resDirect,
819 * (genFunction): changed testing for unspecified interrupt number
820 from 256 to INTNO_UNSPEC,
821 * modified selection scheme of frame pointer generation. Previously
822 if function did use local registers a frame pointer was generated,
823 now a frame pointer is generated only if function has arguments
824 (that need PLUSW2 register access), or has stack arguments, or the
825 compiler is not instructed to omit the frame pointer,
826 * (genEndFunction): before restoring local registers that were saved
827 in the function preamble, also restore the registers that *might*
828 have been allocated for stack access,
829 * (genRet): removed some old comments,
830 * (genCmp, the active (RN's) version): added a call to the
831 pic16_genCmp_special function to perform the compare with a more
832 robust and optimized way,
833 * (genInline): a feature has been added in inline code generation,
834 which allows a wildcard variable substitution when writing inline
835 assembly. Code is incomplete and experimental therefore undocumented,
836 * (genCast): changed order of aopOp for result and right to allow
837 aopForSym to directly load the result if possible,
838 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
839 perform an optimized compare on some selected special occasions,
840 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
841 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
842 generate an IVT any more,
843 * src/pic16/main.c (pic16_optionsTable): added command line option
845 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
846 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
848 * src/pic16/NOTES: Raphael Neider added in list of active developers
849 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
850 jumptable_end to prevent bug #,
851 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
852 inCond and outCond fields,
853 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
854 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
855 turn off register spilling,
856 * (packRegsForOneUse): synced with other ports' versions although it
857 is not used currently,
858 * (pic16_packRegisters): added an optimization while reading
859 structure bitfields, some registers may be saved (malloc code is
860 decreased by 80 bytes)
862 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
864 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
865 left is a bitfield, if yes, then don't optimize assignment. Perhaps
866 this can be optimized more?
868 2005-03-10 Raphael Neider <rneider AT web.de>
870 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
871 genNearPointerGet): (hopefully) fixed access to bitfields via
872 pointers (p->bitN = x; and x = p->bitN; failed)
874 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
876 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
878 2005-03-09 Raphael Neider <rneider AT web.de>
880 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
882 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
884 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
885 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
886 (regTypeNum): set REG_BIT type if necessary
887 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613
888 * support/regression/tests/critical.c: check bug 1144613

1506 Adding support for replacing ljmps with sjmps in jumptables
1507 generated for switch statements. For now you need to set the
1508 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1509 Now 4 algorithms for mcs51 jumptable generation are used:
1510 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1511 addresses loaded pc-relative for up to 112 cases and stack-pushing
1512 target addresses loaded with offset from dptr for up to 256 cases.

1542 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1544 * added libc directory. The current version of LibC contains string
1545 functions, ctype functions and macros and some functions of the
1546 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1547 be extensively tested in the future. Standard disclaimer here.
1548 Library is not automatically build yet. But one can build it by
1549 invoking 'make' inside the libc directory.

1560 * (pic16_storeForReturn): optimized return of 0,
1561 * (genCmp): experimental code for new genCmp which uses PIC18's
1562 special compare&skip instructions. Initial tests fail some times
1563 with variables grater than 1 byte in size, so new code is disabled,
1564 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1566 * (genCast): began a fix to optimize the casting of a bit to another
1567 bit, now assigning a bitfield to another bitfield will fail, sorry,

1576 and 1 for banking instruction,
1577 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1578 caused stop processing pCodes after a inline assembly block,
1579 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1580 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1581 registers when it shouldn't,
1582 * src/pic16/ralloc.c (allocReg): add preliminary support for
1583 supporting a limited set of temporary registers,
1585 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1587 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1588 genDataPointerSet): ensure assignments always copy in MSB to LSB
1590 (loadRegFromAop): recognize CLRH optimization,
1591 (genFunction): optimize RECEIVE iCodes in reentrant functions
1593 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1595 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4593 loaded with the linker search paths (-L arguments) and the libraries
4594 to be linked with the current source (-l arguments). Changes
4595 currently will affect only the pic16 port.
4596 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4597 include path the port specific paths and port specific libraries,
4598 * gplink command now contains the $3 argument,

4616 Documenting changes from previous commits.
4617 * configure.in (version 1.56),
4618 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4619 when generating output files to configure the pic16 library,
4620 but now I've commented it out, since gputils aren't installed in the
4621 SF compile farm, so library won't compile
4623 * device/lib/Makefile.in (version 1.56): initially I've added in
4624 target 'all' the prerequestive 'model-pic16' so it compiled the
4625 pic16 library, but now I've commented it out for the same reasons
4627 * added targets 'model-pic16' and 'objects-pic16' to compile the
4629 * added target 'port-specific-objects-pic16' to handle the
4630 generated libraries and copy them into the build/ directory
4631 * added target 'clean-intermediate-pic16' to clean intermediate
4632 files into pic16 directory
4633 * in target 'installdirs' added line to create directory pic16 in

4909 * src/common.h: added ifndef/define/endif macros
4910 around the header file.
4911 Bug reported from Jesus Calvino-Fraga
4913 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4915 * sdcc.spec: updated
4916 * device/include/Makefile.in: don't install CVS directories
4917 * device/lib/Makefile.in: added removal of CVS directories after install
4918 * doc/Makefile: fixed install, added local_icons
4919 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4920 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4921 * src/ds390/gen.c (genRightShift): fixed bug #870788
4922 * src/SDCCast.c (decorateType): fixed bug #870781
4924 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4926 PIC16 port related changes:
4927 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4928 added variable stackPos,
4930 * gen.c: genCall, assignResultValue: added support for
4931 pushing/retrieving function parameters to/from stack,
4932 genFunction,genEndFunction: setup stack frame for the
4934 genAddrOf: will be changed according to bug 863624
4936 * added files genutils.c and genutils.h which contain gen*
4937 debugged and optimised functions extracted from gen.c
4939 * glue.c: added variable 'externs' which holds extern symbols,
4940 pic16emitRegularMap: is modified to properly handle relocatable
4941 symbols under the new scheme,
4942 pic16createInterruptVect: is modified
4943 pic16printPublics: is modified to emit 'global' assembler directives,
4944 added pic16_printExterns to print extern symbols,
4945 pic16glue: initializes stack/frame pointer in the beginning of
4946 the assembly output. Temporary hack, will be corrected later,
4947 because gplink yet does not support stack and SDCC does not
4948 yet support a type of crt0.o object to create the final binary.
4950 * Removed many lines that contain 8051 legacy code.
4951 * The code is finally placed under a 'code' directive.
4952 * Added port specific options.
4954 * _process_pragma: simplified since now we do not need *special*
4955 include file to define SFR registers. But a separate header
4956 will be needed. This will be developed later.
4957 * _pic16_parseOptions: added, parses port specific options:
4958 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4959 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4960 --preplace-udata-with=
4962 * _pic16_setDefaultOptions: modified to initialize section names,
4963 but hack is temporarly out of order since it needs improvement.
4964 * _pic16_genAssemblerPreamble: configuration words are emitted by
4965 their address instead of their name. This part is incomplete and
4966 supports only the 18Fxx2 devices. Other devices will emit an error
4967 during assembly since they do not contain the same set of config
4969 * _pic16_genIVT: is modified,
4971 * pcode.c: added definitions for some hardware registers that are needed
4973 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4974 All PCI entries are updated. Now LFSR is supported.
4975 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4976 * added pic16_newpCodeOpLit2 to support instructions with
4977 two literal arguments
4978 * pic16_pCode2str: corrected code that emits assembler instructions
4979 with two literal operands and those that have an access bit modifier
4980 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4981 this fixes a bug which caused some labels to be lost, when an
4982 assembler directive was added, i.e. banksel,
4983 * pic16_FixRegisterBanking: improved logic that causes the insertion
4985 * InlineFunction: functions that are called once, are not any more
4986 inlined. This can be a port option in the future,
4988 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4990 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4991 hold the corresponding uninitialized symbols,
4992 * pic16_allocProcessorRegister: registers have explicit marked the
4994 * pic16_allocInternalRegister: registers are explicit marked as
4996 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4997 processing list, so bit registers were lost,
5000 * ralloc.h: added field 'accessBank' and original symbol operand
5001 in register definition,
5002 * removed the field isMapped from register definition,
5004 ** Several functions have been removed from various sources:
5005 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5006 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5007 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5008 pic16_assignRelocatableRegisters
5010 ** others have been introduced:
5011 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5012 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5014 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5016 * support/scripts/inc2h.pl: changed definition of BIT_AT
5017 to emit 'sbit at' instead of 'bit at'. This was a request.
5019 PIC16 port related preliminary changes:
5020 * gen.c: prefixed function popRegFromString with
5021 pic16_ and all references to it corrected
5022 * pcode.c: all pic16_pc_* hardware registers prefixed
5023 with underscore (_),
5024 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5025 * ralloc.c: newReg(): when register is REG_SFR then
5026 set address to rIdx,
5027 pic16_allocProcessorRegister(): marks register wasUsed=0
5028 pic16_writeUsedRegs(): added a call to assign processor
5029 registers via pic16_assignFixedRegisters
5031 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5033 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5034 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5035 variables in unused register banks. Also the SSEG is placed
5036 wherever there is enough space for it, and IDATA can be anywhere
5037 in internal RAM. For now compile using -Wl-Y[stack_size].
5038 The mem file is different for this option as well, since it
5039 makes no sense of talking about DSEG lenght.
5041 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5043 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5044 in certain cases, e.g. when ROM assignment, patch provided
5045 from Albert den Haan.
5047 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5286 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5288 * src/SDCCast.c (decorateType): disabled a transformation I added in
5289 revision 1.188 (access to fields of a structure at an absolute address);
5290 it breaks with bitfields, extern declarations, and gcse analysis.
5291 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5292 could be assigned through a pointer, so don't complain.
5293 * src/SDCCast.c (astErrors),
5295 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5933 support for standard C idiom of memory mapped variables; for
5934 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5935 to xdata int at 0x1234 tempvar = 1.
5936 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5937 provided by Akiya ISHIDA

5953 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5955 Fixed bug #621531 (const & volatile confusion in the type chain).
5956 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6049 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6050 fetching of the pointer
6051 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6052 copied from genNearPointerSet()
6053 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6054 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6068 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6070 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6071 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6072 type for bits was changed. It resulted in bit variables becoming
6073 global, which is not permitted in PIC 14 assembly output.
6075 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6077 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6090 A few small changes that speed up the peephole optimizer.
6094 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6096 Try to make the peephole optimizer smarter by maintaining
6097 an association between the assembly source code and the
6098 iCodes that originated them. Put this information to use
6099 with a new peephole rule condition "notVolatile" so that
6100 the rules can be aggressive yet still safe.
6105 * src/mcs51/peeph.def
6107 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6111 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6112 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6113 if the left or right operand symbols have the accuse flag set.
6115 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6117 Changed the type of the result of the ! (NOT) operator to char;
6118 previously it returned the same type as the source. This allows
6119 us to eliminate all the genFloatNot functions (all of its target
6120 implementations were very buggy) since !float can use the same

6132 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6133 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6134 during interrupts. Ensure WSAVE is located at a shared bank address.
6135 2. Fixed page selection in some places
6136 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6137 the registers name strings.
6138 4. Fixed "signed / unsigned compare" compiler warnings.
6139 5. The PIC port manages its own allocation of the general purpose
6140 registers, but makes no attempt to reuse them. As a result when
6141 compiling it soon runs out of general purpose registers. Some
6142 additional code was added to the files pcode.c and device.c to walk
6143 through the function call tree and rename the registers so that they
6153 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6154 genPlus() & genMinus() when the result is the same as left or right

6160 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6162 Made bitfield a distinct type from bit so that bitfields
6163 convert as per ANSI C and bits retain their traditional
6164 boolean style behaviour. Implemented bitfield support in
6172 * src/ds390/gen.c: bit v bitfield split
6173 * src/z80/gen.c: New support for bitfields
6174 * support/regression/tests/bitfields.c: reenabled z80,
6177 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6179 Rules 246.x, 247.x relate to bitfields, the others speed up
6180 access to xdata mapped I/O devices.
6182 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6184 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6186 Cleaned up genPackBits and genUnpackBits and added two helper
6187 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6188 for literal assignments in genPackBits (thanks to Frieder for
6194 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6196 Fixed bug #748310 (pointer to function type mishandled when the
6197 function name is omitted). Also fixed a SIGSEGV when a function
6198 attribute (reentrant, etc) is used on a non-function or on a
6199 function but misplaced before the parameter list.
6201 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6203 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6204 * support/Util/SDCCerr.h,

6226 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6228 Made the constant following the "interrupt" keyword optional. If
6229 omitted, the function will not automatically be given an entry
6230 in the interrupt vector table (similar to #pragma NOIV, but
6231 less syntacticly kludgy). The interrupt number is also now
6232 range checked. Also fixed a bug in the high order bit example

6246 * src/SDCCicode.c (operandOperation): rewritten some ops
6247 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6248 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6250 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6251 be re-activated by defining REDUCE_LITERALS)
6252 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6253 unsigned, but are signed by default
6254 * src/SDCCval.c (constVal): rearranged
6255 * src/SDCCval.c (valMod): preliminary fix
6256 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6762 added if/endif conditional macros to remove options help
6763 messages from optionsTable when a port is not configured, added
6764 support for the PIc16 port in the ports table, when executing
6765 the compiler with no port specified on command line, a default
6766 port is selected with the new macro DEFAULT_PORT which is
6767 defined in port.h, in setDefaultOptions() linkOptions is removed
6768 from initialization assignment, since now it is a set,
6769 parseCmdLine uses setParseWithComma for linkOptions, in
6770 linkEdit() linkOptions are accessed with new function indexSet()
6771 which returns the i'th item of a set variable. See SDCCset.c, in
6772 linkEdit() when calling buildCmdLine(), added linkOptions as
6773 last argument. Now users can pass arguments to gplink via the
6774 -Wl option, main() uses pic16glue() to glue up pic16 programs

6788 gpasm complaining and test the linkage with gplink, _linkCmd and
6789 _asmCmd changed to be more gplink and gpasm friendly
6790 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6791 produced an error when parsed, peep rule 12 is added to utilize
6792 movff, but it is commented out since the pCode does not support
6793 yet a command with 2 address arguments
6795 2003-05-18 <johan AT balder>
6797 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6824 2003-05-11 Borut Razem <borut.razem AT siol.net>
6826 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7835 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7836 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7838 2003-01-04 <johan AT balder>
7840 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7842 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7843 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7845 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7846 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7847 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7849 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7850 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7852 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7853 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7855 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7856 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7858 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7860 * in \sdcc\as\mcs51\ changed these files in order to create an
7861 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7862 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7863 following files to include the previous two files: aslink.dsp,
7864 Makefile.aslink, Makefile.bcc, and Makefile.in.
7866 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7867 .adb instead of .cdb
7869 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7871 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7872 value from option --iram-size.
7874 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7876 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7879 2002-09-18 <wiml AT hhhh.org>
7881 * SDCClrange.h: exposed setFromRange() and setToRange()
7882 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7883 packRegsForAccUse() (bug 542397)
7884 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7885 multiple times and emitting the fetch operations more than once
7886 added aopGetUsesAcc() function to allow binary operators to
7887 fetch their operands in the correct order; made genMinus() emit
7888 compact code for X = LITERAL - Y
7890 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7891 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7892 sprintf() in line 1267.
7894 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7895 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7898 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7899 Changes to aslink (All the changes are marked with 'JCF'):
7901 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7904 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7905 area BSEG. Also moves, if possible, the DATA area down into the internal
7906 ram so more space is available.
7908 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7911 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7912 not bytes. Function summary() which creates a memory usage summary
7913 file with extension .mem. Reports of overlaping stack and small stack
7914 size. If the space for the stack is less than 16 bytes aslink trows a
7917 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7918 the 8051. Option 'y' for memory summary output file.
7920 Changes to sdcc (All the changes are marked with 'JCF'):
7922 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7924 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7925 overlaying area for it (uses RegBankUsed[4]).
7927 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7928 bank zero as used by default. By default aslink locates the stack
7929 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7930 the creation of the .mem file. Delegates the allocation of data area
7931 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7932 the begining of the stack area to aslink.
7934 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7935 glue() in SDCCglue.c creates an area for it.
7937 2002-09-03 Borut Razem <borut.razem AT siol.net>
7938 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7939 sdcc/src/pic/glue.c:
7940 introduced atexit() handler for teporay files removal in case of
7941 errors, assertions, ...
7943 2002-08-29 Borut Razem <borut.razem AT siol.net>
7944 * sdcc/support/cpp2/auto-host_vc_in.h:
7945 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7946 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7947 Maybe there is a similar problem with BORLANDC? It should be checked!
7949 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7950 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7951 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7952 was not executed, and the compiler (cl) launched a warning:
7953 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7955 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7956 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7958 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7959 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7961 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7962 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7963 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7964 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7965 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7966 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7967 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7968 - added Release configuration in VS projects
7969 - review of compiler an linker options
7970 - VC .exe files are generated in bin_vc directory, not to interfere
7971 with binaries generated from other projects (cygwin, mingw, bcc ...)
7973 * sdcc/src/yacc.dsp: added
7975 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7976 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7977 and insert the version number definitions from .version
7979 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7981 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7982 added - genarate auto-host.h using auto-host_vc_in.h as template
7985 removed from CVS, generated automatically
7987 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7988 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7990 2002-08-11 Borut Razem <borut.razem AT siol.net>
7991 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7993 2002-08-10 Borut Razem <borut.razem AT siol.net>
7994 * src/SDCCmain.c (main):
7995 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7996 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7997 The consequence was that some temporary files were not removed.
8000 unification of code in functions tempfilename() and tempfile():
8001 function tempnam() is defined in Visual Studio 6.0 and .NET
8003 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8005 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8006 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8007 - removed compiler command line option /WX: Treats all warnings as errors
8008 - update a list of source files, included into the project
8010 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8011 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8012 changed project type to Generic Project so that can be correcly converted to VS.NET project
8014 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8016 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8018 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8020 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8021 added return 0 statements after assert() to make compiler happy
8023 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8024 added newline in the def file to keep MSC compiler satisfied
8026 * sdcc/src/z80/gen.c:
8027 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8028 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8029 - solved MSC error in function aopDump()
8031 * sdcc_vc.h: define PREFIX as "\\sdcc"
8033 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8034 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8037 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8038 - Rewrote the register banking algorithm.
8039 - Added pCode live-range analysis to registers (for now, only non-used and
8040 singly-used registers optimized away)
8042 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8044 * 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.

8073 2002-03-28 Johan Knol <johan AT balder>
8075 * src/SDCCval.c: fixed bug #532436
8077 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8079 Added "char *Processor" field to the port structure.
8082 Added -p option. Allows port dependent processor to be specified.
8085 Initialized the new field char *Processor field to NULL in all ports
8088 Compiler generated registers for interrupt context saving
8089 were not getting allocated.
8091 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8094 Fixed left shift. Will promote the left side of a left shift
8095 if a) left shifting more than size of operand or b) when assigned
8096 to something size > size of left side
8098 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8100 tons of changes. Register allocation has been
8101 rewritten. Added customization for the various PICs. Flow

8206 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8208 * sdcc/src/SDCCloop.c:
8209 Previous fix was not good. basic blocks that have "break" or "return" are
8210 not really partof a loop , but live ranges used in these blocks should
8211 be live thru the entire loop, so set partOfLoop but don't add them to
8214 2002-02-21 <johan AT FRIJA>
8216 * src/SDCCcse.c: fixed bug #514308
8218 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8221 Fixed BUG #519583. If a conditional block ended in a return/break
8222 statement inside a loop, it was not being considered part of the loop.
8224 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8226 2002-02-10 Karl Bongers <karl AT turbobit.com>
8229 Fixed up SDCDB debugger somewhat. Updated debugger/README
8230 with lots of comments and notes.
8232 * device/examples/test2.c:
8233 Fix bug, "red" variable not being initialized(compiler complained).
8235 * device/examples/Makefile, examples/test3.c:
8236 Add Makefile in device/examples folder, compiles test3.c
8237 for use as a multiple module SDCDB test case.
8239 * sim/ucsim/cmd.src/cmdset.cc:
8240 Took out debug printfs in ucsim "next" command.
8243 Karl and Johan start ucsim XA support. Most dissassembly working,
8244 about 75% emulation done(plenty of work remaining).
8246 * sim/ucsim/z80.src:
8247 Add Z80 support to ucsim, add test-ucz80 regression test,
8248 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

8282 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8283 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8284 set preprocessor defines (depending on options)
8286 * src/SDCCicode.c, src/SDCCicode.h:
8287 changes made to handle multiple sends & receives
8290 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
