895 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
896 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
897 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
898 immedDom() returning wrong block; probably fixes bug #1160833)
900 2005-03-20 Borut Razem <borut.razem AT siol.net>
902 * support/scripts/inc2h.pl: WIN32 port
904 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
906 * device/lib/makefile.in: added abs.c and labs.c
908 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
910 * device/include/stdint.h: added
911 * device/lib/abs.c: added
912 * device/lib/labs.c: added
913 * device/include/stdlib.h: added abs() and labs() prototypes
914 * device/lib/libsdcc.lib: added abs and labs
915 * device/include/float.h,
916 * device/lib/_fsmul.c,
917 * device/lib/printf_fast.c,
918 * device/lib/printf_tiny.c: updated comments
920 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
922 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
925 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
927 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
928 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
930 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
932 * device/lib/printf_large.c: removed inline assembly for portability and
933 readability. Use printf_fast if speed or size are more important.
934 * src/pic16/gen.c: removed conditions around use of DEBUGpc
935 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
937 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
939 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
940 prevent compiler warning
942 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
944 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
945 moved to level 0 and declared as static. Also they are explicit
946 placed in access bank. This was necessery because some times they
947 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
948 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
949 optimizations. Currently only compare to unsigned char is implemented,
950 * src/pic16/gen.c: added fReturnIdx array,
951 * (struct resolvedIfx) is moved to gen.h and made public,
952 * (struct _G): added sregsAlloc and sregsAllocSet fields,
953 * (aopForSym): added an optimization to directly store in stack of
954 the operand of a SEND iCode,
955 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
956 but as registers instead (AOP_REG) using the fReturnIdx array,
957 * (pic16_freeAsmop): remove the freed register from the
959 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
961 * (pic16_popGetTempRegCond): changed function prototype, now
962 function takes also a bitVector argument v which holds the current
963 set of registers that are allocated for stack access by aopForSym,
964 registers allocated in aopForSym for accessing stack symbols are not
965 any more part of the functions usedRegs field,
966 * (genCall): some times aopOp is called for a stack variable to be
967 send, aopForSym might perform the push, if this is true make sure
968 that genCall doesn't push the variable twice by testing _G.resDirect,
969 * (genFunction): changed testing for unspecified interrupt number
970 from 256 to INTNO_UNSPEC,
971 * modified selection scheme of frame pointer generation. Previously
972 if function did use local registers a frame pointer was generated,
973 now a frame pointer is generated only if function has arguments
974 (that need PLUSW2 register access), or has stack arguments, or the
975 compiler is not instructed to omit the frame pointer,
976 * (genEndFunction): before restoring local registers that were saved
977 in the function preamble, also restore the registers that *might*
978 have been allocated for stack access,
979 * (genRet): removed some old comments,
980 * (genCmp, the active (RN's) version): added a call to the
981 pic16_genCmp_special function to perform the compare with a more
982 robust and optimized way,
983 * (genInline): a feature has been added in inline code generation,
984 which allows a wildcard variable substitution when writing inline
985 assembly. Code is incomplete and experimental therefore undocumented,
986 * (genCast): changed order of aopOp for result and right to allow
987 aopForSym to directly load the result if possible,
988 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
989 perform an optimized compare on some selected special occasions,
990 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
991 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
992 generate an IVT any more,
993 * src/pic16/main.c (pic16_optionsTable): added command line option
995 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
996 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
998 * src/pic16/NOTES: Raphael Neider added in list of active developers
999 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1000 jumptable_end to prevent bug #,
1001 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1002 inCond and outCond fields,
1003 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1004 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1005 turn off register spilling,
1006 * (packRegsForOneUse): synced with other ports' versions although it
1007 is not used currently,
1008 * (pic16_packRegisters): added an optimization while reading
1009 structure bitfields, some registers may be saved (malloc code is
1010 decreased by 80 bytes)
1012 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1014 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1015 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1016 this can be optimized more?
1018 2005-03-10 Raphael Neider <rneider AT web.de>
1020 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1021 genNearPointerGet): (hopefully) fixed access to bitfields via
1022 pointers (p->bitN = x; and x = p->bitN; failed)
1024 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1212 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1213 this might fix SIGSEGVs on MinGW...

1657 generated for switch statements. For now you need to set the
1658 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1659 Now 4 algorithms for mcs51 jumptable generation are used:
1660 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1694 * added libc directory. The current version of LibC contains string
1695 functions, ctype functions and macros and some functions of the
1696 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1697 be extensively tested in the future. Standard disclaimer here.

1711 * (genCmp): experimental code for new genCmp which uses PIC18's
1712 special compare&skip instructions. Initial tests fail some times
1713 with variables grater than 1 byte in size, so new code is disabled,
1714 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1716 * (genCast): began a fix to optimize the casting of a bit to another
1717 bit, now assigning a bitfield to another bitfield will fail, sorry,

1731 registers when it shouldn't,
1732 * src/pic16/ralloc.c (allocReg): add preliminary support for
1733 supporting a limited set of temporary registers,
1735 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1741 (genFunction): optimize RECEIVE iCodes in reentrant functions
1743 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1745 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4740 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4742 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4743 loaded with the linker search paths (-L arguments) and the libraries
4744 to be linked with the current source (-l arguments). Changes
4745 currently will affect only the pic16 port.
4746 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4747 include path the port specific paths and port specific libraries,
4748 * gplink command now contains the $3 argument,
4749 * src/pic16/device.h,
4750 * src/pic16/device.c,: structure PIC_device is made public and

4766 Documenting changes from previous commits.
4767 * configure.in (version 1.56),
4768 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4769 when generating output files to configure the pic16 library,
4770 but now I've commented it out, since gputils aren't installed in the
4771 SF compile farm, so library won't compile
4773 * device/lib/Makefile.in (version 1.56): initially I've added in
4774 target 'all' the prerequestive 'model-pic16' so it compiled the
4775 pic16 library, but now I've commented it out for the same reasons
4777 * added targets 'model-pic16' and 'objects-pic16' to compile the
4779 * added target 'port-specific-objects-pic16' to handle the
4780 generated libraries and copy them into the build/ directory
4781 * added target 'clean-intermediate-pic16' to clean intermediate
4782 files into pic16 directory
4783 * in target 'installdirs' added line to create directory pic16 in
4784 the installation path

4787 added lines to copy all header files to installation path,
4788 * in target 'installdirs' added line create directory for pic16
4789 headers in the installation path

4805 option so that it actually works. Made it specific to the z80, since
4806 the gbz80 doesn't have these kinds of I/O ports.
4808 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4810 * device/include/z180.h,

4837 data are now emitted in sorted order to reduce section naming,
4838 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4839 weren't marked as being in the access bank,

4843 Added portion of GNU PIC Library under the directory
4844 device/include/pic16 and device/lib/pic16. These files
4845 contain the declarations of SFRs for the PIC18Fxx2 devices.
4846 The directory is initialized via configure from toplevel.

4875 * doc/sdccman.lyx: Moved and added some sections, small changes
4876 all over. Telling LaTeX to be less strict with word spacing
4877 to better keep the right margin. Changed some notes about
4878 maintainance of the ports in section 3.2.1 - is it OK like this?
4880 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4882 SDCC source changes:
4883 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4917 UPPER for immediate operands,
4918 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4920 * src/pic16/peeph.def: all peepholes with movff are commented out,
4921 because there is a problem in the pcode peep optimizer,
4922 * src/pic16/ralloc.c: the register allocator can now reuse local

5015 include information about variables allocated to the overlay
5018 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5020 * as/mcs51/lkmain.c: Help about -Y option

5032 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5034 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5035 (default behaviour).
5037 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5039 A python script to validate compiler diagnostic messages. It can be
5040 used to verify that sdcc complains about bad c source code and
5041 gives a good location of the error.
5042 * support/valdiag/Makefile,
5043 * support/valdiag/valdiag.py,
5044 * support/valdiag/tests/*
5046 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5061 Bug reported from Jesus Calvino-Fraga
5063 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5065 * sdcc.spec: updated
5066 * device/include/Makefile.in: don't install CVS directories
5067 * device/lib/Makefile.in: added removal of CVS directories after install
5068 * doc/Makefile: fixed install, added local_icons
5069 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5070 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5071 * src/ds390/gen.c (genRightShift): fixed bug #870788
5072 * src/SDCCast.c (decorateType): fixed bug #870781
5074 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5076 PIC16 port related changes:
5077 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5078 added variable stackPos,
5080 * gen.c: genCall, assignResultValue: added support for
5081 pushing/retrieving function parameters to/from stack,
5082 genFunction,genEndFunction: setup stack frame for the
5084 genAddrOf: will be changed according to bug 863624
5086 * added files genutils.c and genutils.h which contain gen*
5087 debugged and optimised functions extracted from gen.c
5089 * glue.c: added variable 'externs' which holds extern symbols,
5090 pic16emitRegularMap: is modified to properly handle relocatable
5091 symbols under the new scheme,
5092 pic16createInterruptVect: is modified
5093 pic16printPublics: is modified to emit 'global' assembler directives,
5094 added pic16_printExterns to print extern symbols,
5095 pic16glue: initializes stack/frame pointer in the beginning of
5096 the assembly output. Temporary hack, will be corrected later,
5097 because gplink yet does not support stack and SDCC does not
5098 yet support a type of crt0.o object to create the final binary.
5100 * Removed many lines that contain 8051 legacy code.
5101 * The code is finally placed under a 'code' directive.
5102 * Added port specific options.
5104 * _process_pragma: simplified since now we do not need *special*
5105 include file to define SFR registers. But a separate header
5106 will be needed. This will be developed later.
5107 * _pic16_parseOptions: added, parses port specific options:
5108 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5109 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5110 --preplace-udata-with=
5112 * _pic16_setDefaultOptions: modified to initialize section names,
5113 but hack is temporarly out of order since it needs improvement.
5114 * _pic16_genAssemblerPreamble: configuration words are emitted by
5115 their address instead of their name. This part is incomplete and
5116 supports only the 18Fxx2 devices. Other devices will emit an error
5117 during assembly since they do not contain the same set of config
5119 * _pic16_genIVT: is modified,
5121 * pcode.c: added definitions for some hardware registers that are needed
5123 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5124 All PCI entries are updated. Now LFSR is supported.
5125 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5126 * added pic16_newpCodeOpLit2 to support instructions with
5127 two literal arguments
5128 * pic16_pCode2str: corrected code that emits assembler instructions
5129 with two literal operands and those that have an access bit modifier
5130 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5131 this fixes a bug which caused some labels to be lost, when an
5132 assembler directive was added, i.e. banksel,
5133 * pic16_FixRegisterBanking: improved logic that causes the insertion
5135 * InlineFunction: functions that are called once, are not any more
5136 inlined. This can be a port option in the future,
5138 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5140 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5141 hold the corresponding uninitialized symbols,
5142 * pic16_allocProcessorRegister: registers have explicit marked the
5144 * pic16_allocInternalRegister: registers are explicit marked as
5146 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5147 processing list, so bit registers were lost,
5150 * ralloc.h: added field 'accessBank' and original symbol operand
5151 in register definition,
5152 * removed the field isMapped from register definition,
5154 ** Several functions have been removed from various sources:
5155 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5156 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5157 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5158 pic16_assignRelocatableRegisters
5160 ** others have been introduced:
5161 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5162 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5164 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5166 * support/scripts/inc2h.pl: changed definition of BIT_AT
5167 to emit 'sbit at' instead of 'bit at'. This was a request.
5169 PIC16 port related preliminary changes:
5170 * gen.c: prefixed function popRegFromString with
5171 pic16_ and all references to it corrected
5172 * pcode.c: all pic16_pc_* hardware registers prefixed
5173 with underscore (_),
5174 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5175 * ralloc.c: newReg(): when register is REG_SFR then
5176 set address to rIdx,
5177 pic16_allocProcessorRegister(): marks register wasUsed=0
5178 pic16_writeUsedRegs(): added a call to assign processor
5179 registers via pic16_assignFixedRegisters
5181 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5183 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5184 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5185 variables in unused register banks. Also the SSEG is placed
5186 wherever there is enough space for it, and IDATA can be anywhere
5187 in internal RAM. For now compile using -Wl-Y[stack_size].
5188 The mem file is different for this option as well, since it
5189 makes no sense of talking about DSEG lenght.
5191 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5193 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5194 in certain cases, e.g. when ROM assignment, patch provided
5195 from Albert den Haan.
5197 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5340 * src/mcs51/peephole.def,
5341 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5342 (allows non-interrupt and interrupt code to safely compete for a resource

6220 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6221 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6222 type for bits was changed. It resulted in bit variables becoming
6223 global, which is not permitted in PIC 14 assembly output.

6240 A few small changes that speed up the peephole optimizer.
6244 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6246 Try to make the peephole optimizer smarter by maintaining
6247 an association between the assembly source code and the
6248 iCodes that originated them. Put this information to use
6249 with a new peephole rule condition "notVolatile" so that
6250 the rules can be aggressive yet still safe.
6255 * src/mcs51/peeph.def
6257 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6261 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6262 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6263 if the left or right operand symbols have the accuse flag set.
6265 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6267 Changed the type of the result of the ! (NOT) operator to char;
6268 previously it returned the same type as the source. This allows
6269 us to eliminate all the genFloatNot functions (all of its target
6270 implementations were very buggy) since !float can use the same
6273 * src/SDCCicode.c (ast2iCode): ! returns char

6282 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6283 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6284 during interrupts. Ensure WSAVE is located at a shared bank address.
6285 2. Fixed page selection in some places
6286 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6287 the registers name strings.
6288 4. Fixed "signed / unsigned compare" compiler warnings.
6289 5. The PIC port manages its own allocation of the general purpose
6290 registers, but makes no attempt to reuse them. As a result when
6291 compiling it soon runs out of general purpose registers. Some
6292 additional code was added to the files pcode.c and device.c to walk
6293 through the function call tree and rename the registers so that they
6303 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6304 genPlus() & genMinus() when the result is the same as left or right

6310 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6312 Made bitfield a distinct type from bit so that bitfields
6313 convert as per ANSI C and bits retain their traditional
6314 boolean style behaviour. Implemented bitfield support in
6322 * src/ds390/gen.c: bit v bitfield split
6323 * src/z80/gen.c: New support for bitfields
6324 * support/regression/tests/bitfields.c: reenabled z80,
6327 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6329 Rules 246.x, 247.x relate to bitfields, the others speed up
6330 access to xdata mapped I/O devices.
6332 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6334 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6336 Cleaned up genPackBits and genUnpackBits and added two helper

6338 for literal assignments in genPackBits (thanks to Frieder for
6344 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6346 Fixed bug #748310 (pointer to function type mishandled when the
6347 function name is omitted). Also fixed a SIGSEGV when a function
6348 attribute (reentrant, etc) is used on a non-function or on a
6349 function but misplaced before the parameter list.
6351 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6353 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6378 Made the constant following the "interrupt" keyword optional. If
6379 omitted, the function will not automatically be given an entry
6380 in the interrupt vector table (similar to #pragma NOIV, but
6381 less syntacticly kludgy). The interrupt number is also now
6382 range checked. Also fixed a bug in the high order bit example

6914 support for the PIc16 port in the ports table, when executing
6915 the compiler with no port specified on command line, a default
6916 port is selected with the new macro DEFAULT_PORT which is
6917 defined in port.h, in setDefaultOptions() linkOptions is removed
6918 from initialization assignment, since now it is a set,
6919 parseCmdLine uses setParseWithComma for linkOptions, in
6920 linkEdit() linkOptions are accessed with new function indexSet()
6921 which returns the i'th item of a set variable. See SDCCset.c, in
6922 linkEdit() when calling buildCmdLine(), added linkOptions as
6923 last argument. Now users can pass arguments to gplink via the
6924 -Wl option, main() uses pic16glue() to glue up pic16 programs

6938 gpasm complaining and test the linkage with gplink, _linkCmd and
6939 _asmCmd changed to be more gplink and gpasm friendly

7988 2003-01-04 <johan AT balder>
7990 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7992 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8003 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8005 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8006 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8008 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8010 * in \sdcc\as\mcs51\ changed these files in order to create an
8011 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8012 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8013 following files to include the previous two files: aslink.dsp,
8014 Makefile.aslink, Makefile.bcc, and Makefile.in.
8016 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8017 .adb instead of .cdb
8019 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8021 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8022 value from option --iram-size.
8024 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8026 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8029 2002-09-18 <wiml AT hhhh.org>
8031 * SDCClrange.h: exposed setFromRange() and setToRange()
8032 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8033 packRegsForAccUse() (bug 542397)
8034 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8035 multiple times and emitting the fetch operations more than once
8036 added aopGetUsesAcc() function to allow binary operators to
8037 fetch their operands in the correct order; made genMinus() emit
8038 compact code for X = LITERAL - Y
8040 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8041 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8042 sprintf() in line 1267.
8044 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8045 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8048 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8049 Changes to aslink (All the changes are marked with 'JCF'):
8051 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8054 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8055 area BSEG. Also moves, if possible, the DATA area down into the internal
8056 ram so more space is available.
8058 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8061 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8062 not bytes. Function summary() which creates a memory usage summary
8063 file with extension .mem. Reports of overlaping stack and small stack
8064 size. If the space for the stack is less than 16 bytes aslink trows a
8067 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8068 the 8051. Option 'y' for memory summary output file.
8070 Changes to sdcc (All the changes are marked with 'JCF'):
8072 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8074 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8075 overlaying area for it (uses RegBankUsed[4]).
8077 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8078 bank zero as used by default. By default aslink locates the stack
8079 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8080 the creation of the .mem file. Delegates the allocation of data area
8081 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8082 the begining of the stack area to aslink.
8084 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8085 glue() in SDCCglue.c creates an area for it.
8087 2002-09-03 Borut Razem <borut.razem AT siol.net>
8088 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8089 sdcc/src/pic/glue.c:
8090 introduced atexit() handler for teporay files removal in case of
8091 errors, assertions, ...
8093 2002-08-29 Borut Razem <borut.razem AT siol.net>
8094 * sdcc/support/cpp2/auto-host_vc_in.h:
8095 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8096 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8097 Maybe there is a similar problem with BORLANDC? It should be checked!
8099 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8100 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8101 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8102 was not executed, and the compiler (cl) launched a warning:
8103 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8105 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8106 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8108 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8109 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8111 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8112 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8113 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8114 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8115 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8116 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8117 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8118 - added Release configuration in VS projects
8119 - review of compiler an linker options
8120 - VC .exe files are generated in bin_vc directory, not to interfere
8121 with binaries generated from other projects (cygwin, mingw, bcc ...)
8123 * sdcc/src/yacc.dsp: added
8125 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8126 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8127 and insert the version number definitions from .version
8129 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8131 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8132 added - genarate auto-host.h using auto-host_vc_in.h as template
8135 removed from CVS, generated automatically
8137 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8138 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8140 2002-08-11 Borut Razem <borut.razem AT siol.net>
8141 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8143 2002-08-10 Borut Razem <borut.razem AT siol.net>
8144 * src/SDCCmain.c (main):
8145 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8146 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8147 The consequence was that some temporary files were not removed.
8150 unification of code in functions tempfilename() and tempfile():
8151 function tempnam() is defined in Visual Studio 6.0 and .NET
8153 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8155 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8156 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8157 - removed compiler command line option /WX: Treats all warnings as errors
8158 - update a list of source files, included into the project
8160 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8161 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8162 changed project type to Generic Project so that can be correcly converted to VS.NET project
8164 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8166 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8168 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8170 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8171 added return 0 statements after assert() to make compiler happy
8173 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8174 added newline in the def file to keep MSC compiler satisfied
8176 * sdcc/src/z80/gen.c:
8177 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8178 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8179 - solved MSC error in function aopDump()
8181 * sdcc_vc.h: define PREFIX as "\\sdcc"
8183 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8184 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8186 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8187 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8188 - Rewrote the register banking algorithm.
8189 - Added pCode live-range analysis to registers (for now, only non-used and
8190 singly-used registers optimized away)
8192 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8194 * 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.
8196 2002-05-10 Scott Dattalo <scott AT dattalo.com>

8219 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8221 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8223 2002-03-28 Johan Knol <johan AT balder>
8225 * src/SDCCval.c: fixed bug #532436
8227 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8229 Added "char *Processor" field to the port structure.
8232 Added -p option. Allows port dependent processor to be specified.
8235 Initialized the new field char *Processor field to NULL in all ports
8238 Compiler generated registers for interrupt context saving
8239 were not getting allocated.
8241 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8244 Fixed left shift. Will promote the left side of a left shift
8245 if a) left shifting more than size of operand or b) when assigned
8246 to something size > size of left side
8248 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8250 tons of changes. Register allocation has been
8251 rewritten. Added customization for the various PICs. Flow
8252 analysis is restructured. ...
8258 Added. device.c is a PIC port hack to accomodate variations
8261 2002-03-13 Michael Hope <michaelh AT vroom>
8263 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8265 2002-03-04 johanknol <johanknol AT manik>
8267 * /src/SDCCval.c: fixed
8269 const unsigned char arr[][2] = { { 0, 1 } };
8270 t18.c:1: error: Initializer element is not constant
8272 2002-03-04 bela <bela AT manik>
8274 * /device/include/mcs51reg.h:
8275 ds89c420 register definition update
8277 2002-03-03 <johan AT FRIJA>
