895 function takes also a bitVector argument v which holds the current
896 set of registers that are allocated for stack access by aopForSym,
897 registers allocated in aopForSym for accessing stack symbols are not
898 any more part of the functions usedRegs field,
899 * (genCall): some times aopOp is called for a stack variable to be
900 send, aopForSym might perform the push, if this is true make sure
901 that genCall doesn't push the variable twice by testing _G.resDirect,
902 * (genFunction): changed testing for unspecified interrupt number
903 from 256 to INTNO_UNSPEC,
904 * modified selection scheme of frame pointer generation. Previously
905 if function did use local registers a frame pointer was generated,
906 now a frame pointer is generated only if function has arguments
907 (that need PLUSW2 register access), or has stack arguments, or the
908 compiler is not instructed to omit the frame pointer,
909 * (genEndFunction): before restoring local registers that were saved
910 in the function preamble, also restore the registers that *might*
911 have been allocated for stack access,
912 * (genRet): removed some old comments,
913 * (genCmp, the active (RN's) version): added a call to the
914 pic16_genCmp_special function to perform the compare with a more
915 robust and optimized way,
916 * (genInline): a feature has been added in inline code generation,
917 which allows a wildcard variable substitution when writing inline
918 assembly. Code is incomplete and experimental therefore undocumented,
919 * (genCast): changed order of aopOp for result and right to allow
920 aopForSym to directly load the result if possible,
921 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
922 perform an optimized compare on some selected special occasions,
923 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
924 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
925 generate an IVT any more,
926 * src/pic16/main.c (pic16_optionsTable): added command line option
928 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
929 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
931 * src/pic16/NOTES: Raphael Neider added in list of active developers
932 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
933 jumptable_end to prevent bug #,
934 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
935 inCond and outCond fields,
936 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
937 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
938 turn off register spilling,
939 * (packRegsForOneUse): synced with other ports' versions although it
940 is not used currently,
941 * (pic16_packRegisters): added an optimization while reading
942 structure bitfields, some registers may be saved (malloc code is
943 decreased by 80 bytes)
945 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
947 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
948 left is a bitfield, if yes, then don't optimize assignment. Perhaps
949 this can be optimized more?
951 2005-03-10 Raphael Neider <rneider AT web.de>
953 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
954 genNearPointerGet): (hopefully) fixed access to bitfields via
955 pointers (p->bitN = x; and x = p->bitN; failed)

1281 access stack and frame pointers. They are initially assigned to
1282 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1283 accessing SFRs. Updated all occurences of modification of stack or
1284 frame pointer in gen.c and pcode.c,
1285 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
1286 assigning of a literal value to pointers,

1329 from Raphael Neider,
1330 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char

1628 functions, ctype functions and macros and some functions of the
1629 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1630 be extensively tested in the future. Standard disclaimer here.

1644 * (genCmp): experimental code for new genCmp which uses PIC18's
1645 special compare&skip instructions. Initial tests fail some times
1646 with variables grater than 1 byte in size, so new code is disabled,
1647 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1649 * (genCast): began a fix to optimize the casting of a bit to another
1650 bit, now assigning a bitfield to another bitfield will fail, sorry,

1665 * src/pic16/ralloc.c (allocReg): add preliminary support for
1666 supporting a limited set of temporary registers,

4676 loaded with the linker search paths (-L arguments) and the libraries
4677 to be linked with the current source (-l arguments). Changes
4678 currently will affect only the pic16 port.
4679 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4680 include path the port specific paths and port specific libraries,
4681 * gplink command now contains the $3 argument,
4682 * src/pic16/device.h,
4683 * src/pic16/device.c,: structure PIC_device is made public and
4684 renamed to PIC16_device, the same for variable Pics which is renamed

4699 Documenting changes from previous commits.
4700 * configure.in (version 1.56),
4701 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4702 when generating output files to configure the pic16 library,
4703 but now I've commented it out, since gputils aren't installed in the
4704 SF compile farm, so library won't compile
4706 * device/lib/Makefile.in (version 1.56): initially I've added in
4707 target 'all' the prerequestive 'model-pic16' so it compiled the
4708 pic16 library, but now I've commented it out for the same reasons
4710 * added targets 'model-pic16' and 'objects-pic16' to compile the
4712 * added target 'port-specific-objects-pic16' to handle the
4713 generated libraries and copy them into the build/ directory
4714 * added target 'clean-intermediate-pic16' to clean intermediate
4715 files into pic16 directory
4716 * in target 'installdirs' added line to create directory pic16 in

4738 option so that it actually works. Made it specific to the z80, since
4739 the gbz80 doesn't have these kinds of I/O ports.
4741 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4743 * device/include/z180.h,

4770 data are now emitted in sorted order to reduce section naming,
4771 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4772 weren't marked as being in the access bank,

4965 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4967 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4968 (default behaviour).
4970 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4972 A python script to validate compiler diagnostic messages. It can be
4973 used to verify that sdcc complains about bad c source code and
4974 gives a good location of the error.
4975 * support/valdiag/Makefile,
4976 * support/valdiag/valdiag.py,
4977 * support/valdiag/tests/*

4996 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4998 * sdcc.spec: updated
4999 * device/include/Makefile.in: don't install CVS directories

5002 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5003 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5004 * src/ds390/gen.c (genRightShift): fixed bug #870788

5007 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5009 PIC16 port related changes:
5010 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5011 added variable stackPos,
5013 * gen.c: genCall, assignResultValue: added support for
5014 pushing/retrieving function parameters to/from stack,
5015 genFunction,genEndFunction: setup stack frame for the
5017 genAddrOf: will be changed according to bug 863624
5019 * added files genutils.c and genutils.h which contain gen*
5020 debugged and optimised functions extracted from gen.c
5022 * glue.c: added variable 'externs' which holds extern symbols,
5023 pic16emitRegularMap: is modified to properly handle relocatable
5024 symbols under the new scheme,
5025 pic16createInterruptVect: is modified
5026 pic16printPublics: is modified to emit 'global' assembler directives,
5027 added pic16_printExterns to print extern symbols,
5028 pic16glue: initializes stack/frame pointer in the beginning of
5029 the assembly output. Temporary hack, will be corrected later,
5030 because gplink yet does not support stack and SDCC does not
5031 yet support a type of crt0.o object to create the final binary.
5033 * Removed many lines that contain 8051 legacy code.
5034 * The code is finally placed under a 'code' directive.
5035 * Added port specific options.
5037 * _process_pragma: simplified since now we do not need *special*
5038 include file to define SFR registers. But a separate header
5039 will be needed. This will be developed later.
5040 * _pic16_parseOptions: added, parses port specific options:
5041 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5042 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5043 --preplace-udata-with=
5045 * _pic16_setDefaultOptions: modified to initialize section names,
5046 but hack is temporarly out of order since it needs improvement.
5047 * _pic16_genAssemblerPreamble: configuration words are emitted by
5048 their address instead of their name. This part is incomplete and
5049 supports only the 18Fxx2 devices. Other devices will emit an error
5050 during assembly since they do not contain the same set of config
5052 * _pic16_genIVT: is modified,
5054 * pcode.c: added definitions for some hardware registers that are needed
5056 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5057 All PCI entries are updated. Now LFSR is supported.
5058 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5059 * added pic16_newpCodeOpLit2 to support instructions with
5060 two literal arguments
5061 * pic16_pCode2str: corrected code that emits assembler instructions
5062 with two literal operands and those that have an access bit modifier
5063 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5064 this fixes a bug which caused some labels to be lost, when an
5065 assembler directive was added, i.e. banksel,
5066 * pic16_FixRegisterBanking: improved logic that causes the insertion
5068 * InlineFunction: functions that are called once, are not any more
5069 inlined. This can be a port option in the future,
5071 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5073 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5074 hold the corresponding uninitialized symbols,
5075 * pic16_allocProcessorRegister: registers have explicit marked the
5077 * pic16_allocInternalRegister: registers are explicit marked as
5079 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5080 processing list, so bit registers were lost,
5083 * ralloc.h: added field 'accessBank' and original symbol operand
5084 in register definition,
5085 * removed the field isMapped from register definition,
5087 ** Several functions have been removed from various sources:
5088 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5089 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5090 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5091 pic16_assignRelocatableRegisters
5093 ** others have been introduced:
5094 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5095 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5097 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5099 * support/scripts/inc2h.pl: changed definition of BIT_AT
5100 to emit 'sbit at' instead of 'bit at'. This was a request.
5102 PIC16 port related preliminary changes:
5103 * gen.c: prefixed function popRegFromString with
5104 pic16_ and all references to it corrected
5105 * pcode.c: all pic16_pc_* hardware registers prefixed
5106 with underscore (_),
5107 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5108 * ralloc.c: newReg(): when register is REG_SFR then
5109 set address to rIdx,
5110 pic16_allocProcessorRegister(): marks register wasUsed=0
5111 pic16_writeUsedRegs(): added a call to assign processor
5112 registers via pic16_assignFixedRegisters
5114 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5116 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5117 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5118 variables in unused register banks. Also the SSEG is placed
5119 wherever there is enough space for it, and IDATA can be anywhere
5120 in internal RAM. For now compile using -Wl-Y[stack_size].
5121 The mem file is different for this option as well, since it
5122 makes no sense of talking about DSEG lenght.
5124 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5126 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5127 in certain cases, e.g. when ROM assignment, patch provided
5128 from Albert den Haan.
5130 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6132 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6133 fetching of the pointer
6134 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6135 copied from genNearPointerSet()
6136 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6137 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6153 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6154 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6155 type for bits was changed. It resulted in bit variables becoming
6156 global, which is not permitted in PIC 14 assembly output.
6158 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6173 A few small changes that speed up the peephole optimizer.
6177 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6179 Try to make the peephole optimizer smarter by maintaining
6180 an association between the assembly source code and the
6181 iCodes that originated them. Put this information to use
6182 with a new peephole rule condition "notVolatile" so that
6183 the rules can be aggressive yet still safe.
6188 * src/mcs51/peeph.def
6190 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6194 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6195 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6196 if the left or right operand symbols have the accuse flag set.
6198 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6200 Changed the type of the result of the ! (NOT) operator to char;
6201 previously it returned the same type as the source. This allows
6202 us to eliminate all the genFloatNot functions (all of its target
6203 implementations were very buggy) since !float can use the same

6215 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6216 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6217 during interrupts. Ensure WSAVE is located at a shared bank address.
6218 2. Fixed page selection in some places
6219 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6220 the registers name strings.
6221 4. Fixed "signed / unsigned compare" compiler warnings.
6222 5. The PIC port manages its own allocation of the general purpose
6223 registers, but makes no attempt to reuse them. As a result when
6224 compiling it soon runs out of general purpose registers. Some
6225 additional code was added to the files pcode.c and device.c to walk
6226 through the function call tree and rename the registers so that they
6236 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6243 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6245 Made bitfield a distinct type from bit so that bitfields
6246 convert as per ANSI C and bits retain their traditional
6247 boolean style behaviour. Implemented bitfield support in
6255 * src/ds390/gen.c: bit v bitfield split
6256 * src/z80/gen.c: New support for bitfields
6257 * support/regression/tests/bitfields.c: reenabled z80,
6260 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6262 Rules 246.x, 247.x relate to bitfields, the others speed up
6263 access to xdata mapped I/O devices.
6265 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6267 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6269 Cleaned up genPackBits and genUnpackBits and added two helper
6270 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6271 for literal assignments in genPackBits (thanks to Frieder for
6277 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6279 Fixed bug #748310 (pointer to function type mishandled when the
6280 function name is omitted). Also fixed a SIGSEGV when a function
6281 attribute (reentrant, etc) is used on a non-function or on a
6282 function but misplaced before the parameter list.
6284 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6286 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6287 * support/Util/SDCCerr.h,

6309 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6311 Made the constant following the "interrupt" keyword optional. If
6312 omitted, the function will not automatically be given an entry
6313 in the interrupt vector table (similar to #pragma NOIV, but
6314 less syntacticly kludgy). The interrupt number is also now
6315 range checked. Also fixed a bug in the high order bit example

6845 added if/endif conditional macros to remove options help
6846 messages from optionsTable when a port is not configured, added
6847 support for the PIc16 port in the ports table, when executing
6848 the compiler with no port specified on command line, a default
6849 port is selected with the new macro DEFAULT_PORT which is
6850 defined in port.h, in setDefaultOptions() linkOptions is removed
6851 from initialization assignment, since now it is a set,
6852 parseCmdLine uses setParseWithComma for linkOptions, in
6853 linkEdit() linkOptions are accessed with new function indexSet()
6854 which returns the i'th item of a set variable. See SDCCset.c, in
6855 linkEdit() when calling buildCmdLine(), added linkOptions as
6856 last argument. Now users can pass arguments to gplink via the
6857 -Wl option, main() uses pic16glue() to glue up pic16 programs

6871 gpasm complaining and test the linkage with gplink, _linkCmd and
6872 _asmCmd changed to be more gplink and gpasm friendly
6873 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6874 produced an error when parsed, peep rule 12 is added to utilize
6875 movff, but it is commented out since the pCode does not support
6876 yet a command with 2 address arguments
6878 2003-05-18 <johan AT balder>
6880 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7898 2003-01-07 <johan AT balder>
7900 * src/SDCCast.c (decorateType): fixed bug #600035

7913 2003-01-06 <johan AT balder>
7915 * src/SDCCicode.c: fixed array add
7917 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7918 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7919 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7921 2003-01-04 <johan AT balder>
7923 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7925 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7926 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7928 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7929 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7935 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7936 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7938 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7939 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7941 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7943 * in \sdcc\as\mcs51\ changed these files in order to create an
7944 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7945 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7946 following files to include the previous two files: aslink.dsp,
7947 Makefile.aslink, Makefile.bcc, and Makefile.in.
7949 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7950 .adb instead of .cdb
7952 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7954 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7955 value from option --iram-size.
7957 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7959 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7962 2002-09-18 <wiml AT hhhh.org>
7964 * SDCClrange.h: exposed setFromRange() and setToRange()
7965 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7966 packRegsForAccUse() (bug 542397)
7967 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7968 multiple times and emitting the fetch operations more than once
7969 added aopGetUsesAcc() function to allow binary operators to
7970 fetch their operands in the correct order; made genMinus() emit
7971 compact code for X = LITERAL - Y
7973 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7974 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7975 sprintf() in line 1267.
7977 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7978 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7981 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7982 Changes to aslink (All the changes are marked with 'JCF'):
7984 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7987 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7988 area BSEG. Also moves, if possible, the DATA area down into the internal
7989 ram so more space is available.
7991 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7994 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7995 not bytes. Function summary() which creates a memory usage summary
7996 file with extension .mem. Reports of overlaping stack and small stack
7997 size. If the space for the stack is less than 16 bytes aslink trows a
8000 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8001 the 8051. Option 'y' for memory summary output file.
8003 Changes to sdcc (All the changes are marked with 'JCF'):
8005 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8007 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8008 overlaying area for it (uses RegBankUsed[4]).
8010 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8011 bank zero as used by default. By default aslink locates the stack
8012 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8013 the creation of the .mem file. Delegates the allocation of data area
8014 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8015 the begining of the stack area to aslink.
8017 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8018 glue() in SDCCglue.c creates an area for it.
8020 2002-09-03 Borut Razem <borut.razem AT siol.net>
8021 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8022 sdcc/src/pic/glue.c:
8023 introduced atexit() handler for teporay files removal in case of
8024 errors, assertions, ...
8026 2002-08-29 Borut Razem <borut.razem AT siol.net>
8027 * sdcc/support/cpp2/auto-host_vc_in.h:
8028 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8029 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8030 Maybe there is a similar problem with BORLANDC? It should be checked!
8032 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8033 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8034 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8035 was not executed, and the compiler (cl) launched a warning:
8036 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8038 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8039 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8041 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8042 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8044 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8045 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8046 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8047 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8048 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8049 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8050 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8051 - added Release configuration in VS projects
8052 - review of compiler an linker options
8053 - VC .exe files are generated in bin_vc directory, not to interfere
8054 with binaries generated from other projects (cygwin, mingw, bcc ...)
8056 * sdcc/src/yacc.dsp: added
8058 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8059 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8060 and insert the version number definitions from .version
8062 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8064 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8065 added - genarate auto-host.h using auto-host_vc_in.h as template
8068 removed from CVS, generated automatically
8070 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8071 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8073 2002-08-11 Borut Razem <borut.razem AT siol.net>
8074 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8076 2002-08-10 Borut Razem <borut.razem AT siol.net>
8077 * src/SDCCmain.c (main):
8078 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8079 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8080 The consequence was that some temporary files were not removed.
8083 unification of code in functions tempfilename() and tempfile():
8084 function tempnam() is defined in Visual Studio 6.0 and .NET
8086 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8088 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8089 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8090 - removed compiler command line option /WX: Treats all warnings as errors
8091 - update a list of source files, included into the project
8093 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8094 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8095 changed project type to Generic Project so that can be correcly converted to VS.NET project
8097 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8099 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8101 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8103 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8104 added return 0 statements after assert() to make compiler happy
8106 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8107 added newline in the def file to keep MSC compiler satisfied
8109 * sdcc/src/z80/gen.c:
8110 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8111 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8112 - solved MSC error in function aopDump()
8114 * sdcc_vc.h: define PREFIX as "\\sdcc"
8116 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8117 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8119 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8120 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8121 - Rewrote the register banking algorithm.
8122 - Added pCode live-range analysis to registers (for now, only non-used and
8123 singly-used registers optimized away)
8125 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8127 * 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.
8129 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8130 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8132 2002-04-22 Michael Hope <michaelh AT vroom>

8152 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8154 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8156 2002-03-28 Johan Knol <johan AT balder>
8158 * src/SDCCval.c: fixed bug #532436
8160 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8162 Added "char *Processor" field to the port structure.
8165 Added -p option. Allows port dependent processor to be specified.
8168 Initialized the new field char *Processor field to NULL in all ports
8171 Compiler generated registers for interrupt context saving
8172 were not getting allocated.
8174 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8177 Fixed left shift. Will promote the left side of a left shift
8178 if a) left shifting more than size of operand or b) when assigned
8179 to something size > size of left side
8181 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8183 tons of changes. Register allocation has been
8184 rewritten. Added customization for the various PICs. Flow
8185 analysis is restructured. ...
8191 Added. device.c is a PIC port hack to accomodate variations
8194 2002-03-13 Michael Hope <michaelh AT vroom>
8196 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8198 2002-03-04 johanknol <johanknol AT manik>
8200 * /src/SDCCval.c: fixed
8202 const unsigned char arr[][2] = { { 0, 1 } };
8203 t18.c:1: error: Initializer element is not constant
8205 2002-03-04 bela <bela AT manik>
8207 * /device/include/mcs51reg.h:
8208 ds89c420 register definition update
8210 2002-03-03 <johan AT FRIJA>

8289 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8291 * sdcc/src/SDCCloop.c:
8292 Previous fix was not good. basic blocks that have "break" or "return" are
8293 not really partof a loop , but live ranges used in these blocks should
8294 be live thru the entire loop, so set partOfLoop but don't add them to
8297 2002-02-21 <johan AT FRIJA>
8299 * src/SDCCcse.c: fixed bug #514308
8301 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8304 Fixed BUG #519583. If a conditional block ended in a return/break
8305 statement inside a loop, it was not being considered part of the loop.
8307 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8309 2002-02-10 Karl Bongers <karl AT turbobit.com>
