2128 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2130 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2131 moved to level 0 and declared as static. Also they are explicit
2132 placed in access bank. This was necessery because some times they
2133 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2134 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2135 optimizations. Currently only compare to unsigned char is implemented,

2144 _G.sregsAlloc field,
2145 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2146 a compare of 'WREG',
2147 * (pic16_popGetTempRegCond): changed function prototype, now
2148 function takes also a bitVector argument v which holds the current
2149 set of registers that are allocated for stack access by aopForSym,
2150 registers allocated in aopForSym for accessing stack symbols are not
2151 any more part of the functions usedRegs field,
2152 * (genCall): some times aopOp is called for a stack variable to be
2153 send, aopForSym might perform the push, if this is true make sure
2154 that genCall doesn't push the variable twice by testing _G.resDirect,
2155 * (genFunction): changed testing for unspecified interrupt number
2156 from 256 to INTNO_UNSPEC,
2157 * modified selection scheme of frame pointer generation. Previously
2158 if function did use local registers a frame pointer was generated,
2159 now a frame pointer is generated only if function has arguments
2160 (that need PLUSW2 register access), or has stack arguments, or the
2161 compiler is not instructed to omit the frame pointer,
2162 * (genEndFunction): before restoring local registers that were saved
2163 in the function preamble, also restore the registers that *might*
2164 have been allocated for stack access,
2165 * (genRet): removed some old comments,
2166 * (genCmp, the active (RN's) version): added a call to the
2167 pic16_genCmp_special function to perform the compare with a more
2168 robust and optimized way,
2169 * (genInline): a feature has been added in inline code generation,
2170 which allows a wildcard variable substitution when writing inline
2171 assembly. Code is incomplete and experimental therefore undocumented,
2172 * (genCast): changed order of aopOp for result and right to allow
2173 aopForSym to directly load the result if possible,
2174 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2175 perform an optimized compare on some selected special occasions,
2176 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2177 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2178 generate an IVT any more,
2179 * src/pic16/main.c (pic16_optionsTable): added command line option
2181 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2182 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2184 * src/pic16/NOTES: Raphael Neider added in list of active developers
2185 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2186 jumptable_end to prevent bug #,
2187 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2188 inCond and outCond fields,
2189 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2190 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2191 turn off register spilling,
2192 * (packRegsForOneUse): synced with other ports' versions although it
2193 is not used currently,
2194 * (pic16_packRegisters): added an optimization while reading
2195 structure bitfields, some registers may be saved (malloc code is
2196 decreased by 80 bytes)
2198 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2200 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2201 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2202 this can be optimized more?
2204 2005-03-10 Raphael Neider <rneider AT web.de>
2206 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2207 genNearPointerGet): (hopefully) fixed access to bitfields via
2208 pointers (p->bitN = x; and x = p->bitN; failed)

2534 access stack and frame pointers. They are initially assigned to
2535 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2536 accessing SFRs. Updated all occurences of modification of stack or
2537 frame pointer in gen.c and pcode.c,

2582 from Raphael Neider,
2583 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
2584 for 8-bit literals. This fixes some literal operands which are sign
2585 extended to 16-bits ints when instruction needs only 8-bits.

2842 Adding support for replacing ljmps with sjmps in jumptables
2843 generated for switch statements. For now you need to set the
2844 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2845 Now 4 algorithms for mcs51 jumptable generation are used:
2846 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2847 addresses loaded pc-relative for up to 112 cases and stack-pushing
2848 target addresses loaded with offset from dptr for up to 256 cases.

2880 * added libc directory. The current version of LibC contains string
2881 functions, ctype functions and macros and some functions of the
2882 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2883 be extensively tested in the future. Standard disclaimer here.

2896 * (pic16_storeForReturn): optimized return of 0,
2897 * (genCmp): experimental code for new genCmp which uses PIC18's
2898 special compare&skip instructions. Initial tests fail some times
2899 with variables grater than 1 byte in size, so new code is disabled,
2900 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2902 * (genCast): began a fix to optimize the casting of a bit to another
2903 bit, now assigning a bitfield to another bitfield will fail, sorry,

2912 and 1 for banking instruction,
2913 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2914 caused stop processing pCodes after a inline assembly block,
2915 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2917 registers when it shouldn't,
2918 * src/pic16/ralloc.c (allocReg): add preliminary support for
2919 supporting a limited set of temporary registers,
2921 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5929 loaded with the linker search paths (-L arguments) and the libraries
5930 to be linked with the current source (-l arguments). Changes
5931 currently will affect only the pic16 port.
5932 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5933 include path the port specific paths and port specific libraries,
5934 * gplink command now contains the $3 argument,
5935 * src/pic16/device.h,
5936 * src/pic16/device.c,: structure PIC_device is made public and
5937 renamed to PIC16_device, the same for variable Pics which is renamed

5952 Documenting changes from previous commits.
5953 * configure.in (version 1.56),
5954 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5955 when generating output files to configure the pic16 library,
5956 but now I've commented it out, since gputils aren't installed in the
5957 SF compile farm, so library won't compile
5959 * device/lib/Makefile.in (version 1.56): initially I've added in
5960 target 'all' the prerequestive 'model-pic16' so it compiled the
5961 pic16 library, but now I've commented it out for the same reasons
5963 * added targets 'model-pic16' and 'objects-pic16' to compile the
5965 * added target 'port-specific-objects-pic16' to handle the
5966 generated libraries and copy them into the build/ directory
5967 * added target 'clean-intermediate-pic16' to clean intermediate
5968 files into pic16 directory
5969 * in target 'installdirs' added line to create directory pic16 in

6145 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6148 * src/z80/main.c: added missed needLinkerScript flags (more than
6149 one port structure defined in these file)
6150 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
6153 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

6156 * src/port.h: added flag needLinkerScript in port->linker
6157 structure to inform whether to create a .lnk file or not,
6165 * src/z80/main.c: changed appropriately to configure
6166 needLinkerScript flag
6168 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6169 * src/pic/glue.c: added variable udata_section_name to
6170 override default uninitialized data segment definition for
6171 devices only with SHAREBANK memory (reported from Erik Epetrich)
6172 * (pic14emitOverlay): modified to emit a commented overlay segment
6173 directive when no overlay data exist
6174 * (picglue): modified to emit uninitialized data segment
6175 according to udata_section_name

6179 * modified _linkCmd and _asmCmd to include compiler passed
6180 arguments via -W option
6181 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6182 object file from '.rel' to '.o' in port->linker structure,
6183 changed size of fptr from 2 to 3 in port structure
6185 2004-01-07 Borut Razem <borut.razem AT siol.net>
6187 * support/scripts/sdcc.nsi: update PATH
6188 * support/scripts/sdcc.ico: craeted

6201 include information about variables allocated to the overlay
6204 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6206 * as/mcs51/lkmain.c: Help about -Y option
6207 * as/mcs51/lkarea.c: Fixed gcc warnings
6209 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

6213 * support/valdiag/tests/overflow.c: added
6214 * src/SDCCast.c (decorateType),
6215 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6216 LEFT_OP (left shift)
6218 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6220 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6221 (default behaviour).
6223 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6225 A python script to validate compiler diagnostic messages. It can be
6226 used to verify that sdcc complains about bad c source code and
6227 gives a good location of the error.
6228 * support/valdiag/Makefile,
6229 * support/valdiag/valdiag.py,
6230 * support/valdiag/tests/*
6232 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6245 * src/common.h: added ifndef/define/endif macros
6246 around the header file.
6247 Bug reported from Jesus Calvino-Fraga
6249 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6251 * sdcc.spec: updated
6252 * device/include/Makefile.in: don't install CVS directories
6253 * device/lib/Makefile.in: added removal of CVS directories after install
6254 * doc/Makefile: fixed install, added local_icons
6255 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6256 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6257 * src/ds390/gen.c (genRightShift): fixed bug #870788
6258 * src/SDCCast.c (decorateType): fixed bug #870781
6260 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6262 PIC16 port related changes:
6263 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6264 added variable stackPos,
6266 * gen.c: genCall, assignResultValue: added support for
6267 pushing/retrieving function parameters to/from stack,
6268 genFunction,genEndFunction: setup stack frame for the
6270 genAddrOf: will be changed according to bug 863624
6272 * added files genutils.c and genutils.h which contain gen*
6273 debugged and optimised functions extracted from gen.c
6275 * glue.c: added variable 'externs' which holds extern symbols,
6276 pic16emitRegularMap: is modified to properly handle relocatable
6277 symbols under the new scheme,
6278 pic16createInterruptVect: is modified
6279 pic16printPublics: is modified to emit 'global' assembler directives,
6280 added pic16_printExterns to print extern symbols,
6281 pic16glue: initializes stack/frame pointer in the beginning of
6282 the assembly output. Temporary hack, will be corrected later,
6283 because gplink yet does not support stack and SDCC does not
6284 yet support a type of crt0.o object to create the final binary.
6286 * Removed many lines that contain 8051 legacy code.
6287 * The code is finally placed under a 'code' directive.
6288 * Added port specific options.
6290 * _process_pragma: simplified since now we do not need *special*
6291 include file to define SFR registers. But a separate header
6292 will be needed. This will be developed later.
6293 * _pic16_parseOptions: added, parses port specific options:
6294 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6295 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6296 --preplace-udata-with=
6298 * _pic16_setDefaultOptions: modified to initialize section names,
6299 but hack is temporarly out of order since it needs improvement.
6300 * _pic16_genAssemblerPreamble: configuration words are emitted by
6301 their address instead of their name. This part is incomplete and
6302 supports only the 18Fxx2 devices. Other devices will emit an error
6303 during assembly since they do not contain the same set of config
6305 * _pic16_genIVT: is modified,
6307 * pcode.c: added definitions for some hardware registers that are needed
6309 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6310 All PCI entries are updated. Now LFSR is supported.
6311 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6312 * added pic16_newpCodeOpLit2 to support instructions with
6313 two literal arguments
6314 * pic16_pCode2str: corrected code that emits assembler instructions
6315 with two literal operands and those that have an access bit modifier
6316 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6317 this fixes a bug which caused some labels to be lost, when an
6318 assembler directive was added, i.e. banksel,
6319 * pic16_FixRegisterBanking: improved logic that causes the insertion
6321 * InlineFunction: functions that are called once, are not any more
6322 inlined. This can be a port option in the future,
6324 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6326 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6327 hold the corresponding uninitialized symbols,
6328 * pic16_allocProcessorRegister: registers have explicit marked the
6330 * pic16_allocInternalRegister: registers are explicit marked as
6332 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6333 processing list, so bit registers were lost,
6336 * ralloc.h: added field 'accessBank' and original symbol operand
6337 in register definition,
6338 * removed the field isMapped from register definition,
6340 ** Several functions have been removed from various sources:
6341 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6342 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6343 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6344 pic16_assignRelocatableRegisters
6346 ** others have been introduced:
6347 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6348 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6350 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6352 * support/scripts/inc2h.pl: changed definition of BIT_AT
6353 to emit 'sbit at' instead of 'bit at'. This was a request.
6355 PIC16 port related preliminary changes:
6356 * gen.c: prefixed function popRegFromString with
6357 pic16_ and all references to it corrected
6358 * pcode.c: all pic16_pc_* hardware registers prefixed
6359 with underscore (_),
6360 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6361 * ralloc.c: newReg(): when register is REG_SFR then
6362 set address to rIdx,
6363 pic16_allocProcessorRegister(): marks register wasUsed=0
6364 pic16_writeUsedRegs(): added a call to assign processor
6365 registers via pic16_assignFixedRegisters
6367 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6369 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6370 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6371 variables in unused register banks. Also the SSEG is placed
6372 wherever there is enough space for it, and IDATA can be anywhere
6373 in internal RAM. For now compile using -Wl-Y[stack_size].
6374 The mem file is different for this option as well, since it
6375 makes no sense of talking about DSEG lenght.
6377 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6379 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6380 in certain cases, e.g. when ROM assignment, patch provided
6381 from Albert den Haan.
6383 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6622 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6624 * src/SDCCast.c (decorateType): disabled a transformation I added in
6625 revision 1.188 (access to fields of a structure at an absolute address);

7388 copied from genNearPointerSet()
7389 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7390 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7406 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7407 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7408 type for bits was changed. It resulted in bit variables becoming

7426 A few small changes that speed up the peephole optimizer.
7430 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7432 Try to make the peephole optimizer smarter by maintaining
7433 an association between the assembly source code and the
7434 iCodes that originated them. Put this information to use
7435 with a new peephole rule condition "notVolatile" so that
7436 the rules can be aggressive yet still safe.
7441 * src/mcs51/peeph.def
7443 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7447 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7448 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7449 if the left or right operand symbols have the accuse flag set.
7451 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7453 Changed the type of the result of the ! (NOT) operator to char;
7454 previously it returned the same type as the source. This allows
7455 us to eliminate all the genFloatNot functions (all of its target
7456 implementations were very buggy) since !float can use the same

7468 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7469 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7470 during interrupts. Ensure WSAVE is located at a shared bank address.
7471 2. Fixed page selection in some places
7472 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7473 the registers name strings.
7474 4. Fixed "signed / unsigned compare" compiler warnings.
7475 5. The PIC port manages its own allocation of the general purpose
7476 registers, but makes no attempt to reuse them. As a result when
7477 compiling it soon runs out of general purpose registers. Some
7478 additional code was added to the files pcode.c and device.c to walk
7479 through the function call tree and rename the registers so that they
7489 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7496 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7498 Made bitfield a distinct type from bit so that bitfields
7499 convert as per ANSI C and bits retain their traditional
7500 boolean style behaviour. Implemented bitfield support in
7508 * src/ds390/gen.c: bit v bitfield split
7509 * src/z80/gen.c: New support for bitfields

7513 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7515 Rules 246.x, 247.x relate to bitfields, the others speed up
7516 access to xdata mapped I/O devices.
7518 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7520 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7522 Cleaned up genPackBits and genUnpackBits and added two helper
7523 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7524 for literal assignments in genPackBits (thanks to Frieder for
7530 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7532 Fixed bug #748310 (pointer to function type mishandled when the
7533 function name is omitted). Also fixed a SIGSEGV when a function
7534 attribute (reentrant, etc) is used on a non-function or on a
7535 function but misplaced before the parameter list.

7562 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7564 Made the constant following the "interrupt" keyword optional. If
7565 omitted, the function will not automatically be given an entry
7566 in the interrupt vector table (similar to #pragma NOIV, but
7567 less syntacticly kludgy). The interrupt number is also now
7568 range checked. Also fixed a bug in the high order bit example

8098 added if/endif conditional macros to remove options help
8099 messages from optionsTable when a port is not configured, added
8100 support for the PIc16 port in the ports table, when executing
8101 the compiler with no port specified on command line, a default
8102 port is selected with the new macro DEFAULT_PORT which is
8103 defined in port.h, in setDefaultOptions() linkOptions is removed
8104 from initialization assignment, since now it is a set,
8105 parseCmdLine uses setParseWithComma for linkOptions, in
8106 linkEdit() linkOptions are accessed with new function indexSet()
8107 which returns the i'th item of a set variable. See SDCCset.c, in
8108 linkEdit() when calling buildCmdLine(), added linkOptions as
8109 last argument. Now users can pass arguments to gplink via the
8110 -Wl option, main() uses pic16glue() to glue up pic16 programs

8124 gpasm complaining and test the linkage with gplink, _linkCmd and
8125 _asmCmd changed to be more gplink and gpasm friendly
8126 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8127 produced an error when parsed, peep rule 12 is added to utilize
8128 movff, but it is commented out since the pCode does not support
8129 yet a command with 2 address arguments
8131 2003-05-18 <johan AT balder>
8133 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9166 2003-01-06 <johan AT balder>
9168 * src/SDCCicode.c: fixed array add
9170 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9171 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9172 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9174 2003-01-04 <johan AT balder>
9176 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9178 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9179 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9181 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9182 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9191 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9192 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9194 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9196 * in \sdcc\as\mcs51\ changed these files in order to create an
9197 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9198 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9199 following files to include the previous two files: aslink.dsp,
9200 Makefile.aslink, Makefile.bcc, and Makefile.in.
9202 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9203 .adb instead of .cdb
9205 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9207 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9208 value from option --iram-size.
9210 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9212 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9215 2002-09-18 <wiml AT hhhh.org>
9217 * SDCClrange.h: exposed setFromRange() and setToRange()
9218 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9219 packRegsForAccUse() (bug 542397)
9220 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9221 multiple times and emitting the fetch operations more than once
9222 added aopGetUsesAcc() function to allow binary operators to
9223 fetch their operands in the correct order; made genMinus() emit
9224 compact code for X = LITERAL - Y
9226 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9227 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9228 sprintf() in line 1267.
9230 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9231 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9234 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9235 Changes to aslink (All the changes are marked with 'JCF'):
9237 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9240 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9241 area BSEG. Also moves, if possible, the DATA area down into the internal
9242 ram so more space is available.
9244 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9247 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9248 not bytes. Function summary() which creates a memory usage summary
9249 file with extension .mem. Reports of overlaping stack and small stack
9250 size. If the space for the stack is less than 16 bytes aslink trows a
9253 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9254 the 8051. Option 'y' for memory summary output file.
9256 Changes to sdcc (All the changes are marked with 'JCF'):
9258 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9260 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9261 overlaying area for it (uses RegBankUsed[4]).
9263 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9264 bank zero as used by default. By default aslink locates the stack
9265 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9266 the creation of the .mem file. Delegates the allocation of data area
9267 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9268 the begining of the stack area to aslink.
9270 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9271 glue() in SDCCglue.c creates an area for it.
9273 2002-09-03 Borut Razem <borut.razem AT siol.net>
9274 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9275 sdcc/src/pic/glue.c:
9276 introduced atexit() handler for teporay files removal in case of
9277 errors, assertions, ...
9279 2002-08-29 Borut Razem <borut.razem AT siol.net>
9280 * sdcc/support/cpp2/auto-host_vc_in.h:
9281 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9282 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9283 Maybe there is a similar problem with BORLANDC? It should be checked!
9285 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9286 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9287 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9288 was not executed, and the compiler (cl) launched a warning:
9289 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9291 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9292 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9294 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9295 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9297 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9298 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9299 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9300 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9301 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9302 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9303 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9304 - added Release configuration in VS projects
9305 - review of compiler an linker options
9306 - VC .exe files are generated in bin_vc directory, not to interfere
9307 with binaries generated from other projects (cygwin, mingw, bcc ...)
9309 * sdcc/src/yacc.dsp: added
9311 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9312 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9313 and insert the version number definitions from .version
9315 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9317 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9318 added - genarate auto-host.h using auto-host_vc_in.h as template
9321 removed from CVS, generated automatically
9323 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9324 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9326 2002-08-11 Borut Razem <borut.razem AT siol.net>
9327 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9329 2002-08-10 Borut Razem <borut.razem AT siol.net>
9330 * src/SDCCmain.c (main):
9331 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9332 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9333 The consequence was that some temporary files were not removed.
9336 unification of code in functions tempfilename() and tempfile():
9337 function tempnam() is defined in Visual Studio 6.0 and .NET
9339 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9341 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9342 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9343 - removed compiler command line option /WX: Treats all warnings as errors
9344 - update a list of source files, included into the project
9346 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9347 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9348 changed project type to Generic Project so that can be correcly converted to VS.NET project
9350 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9352 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9354 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9356 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9357 added return 0 statements after assert() to make compiler happy
9359 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9360 added newline in the def file to keep MSC compiler satisfied
9362 * sdcc/src/z80/gen.c:
9363 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9364 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9365 - solved MSC error in function aopDump()
9367 * sdcc_vc.h: define PREFIX as "\\sdcc"
9369 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9370 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9372 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9373 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9374 - Rewrote the register banking algorithm.
9375 - Added pCode live-range analysis to registers (for now, only non-used and
9376 singly-used registers optimized away)
9378 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9380 * 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.

9407 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9409 2002-03-28 Johan Knol <johan AT balder>
9411 * src/SDCCval.c: fixed bug #532436
9413 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9415 Added "char *Processor" field to the port structure.
9418 Added -p option. Allows port dependent processor to be specified.
9421 Initialized the new field char *Processor field to NULL in all ports
9424 Compiler generated registers for interrupt context saving
9425 were not getting allocated.
9427 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9430 Fixed left shift. Will promote the left side of a left shift
9431 if a) left shifting more than size of operand or b) when assigned
9432 to something size > size of left side
9434 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9436 tons of changes. Register allocation has been
9437 rewritten. Added customization for the various PICs. Flow
9438 analysis is restructured. ...
9444 Added. device.c is a PIC port hack to accomodate variations
9447 2002-03-13 Michael Hope <michaelh AT vroom>
9449 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9451 2002-03-04 johanknol <johanknol AT manik>
9453 * /src/SDCCval.c: fixed
9455 const unsigned char arr[][2] = { { 0, 1 } };
9456 t18.c:1: error: Initializer element is not constant
9458 2002-03-04 bela <bela AT manik>
9460 * /device/include/mcs51reg.h:
9461 ds89c420 register definition update
9463 2002-03-03 <johan AT FRIJA>

9542 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9544 * sdcc/src/SDCCloop.c:
9545 Previous fix was not good. basic blocks that have "break" or "return" are
9546 not really partof a loop , but live ranges used in these blocks should
9547 be live thru the entire loop, so set partOfLoop but don't add them to
9550 2002-02-21 <johan AT FRIJA>
9552 * src/SDCCcse.c: fixed bug #514308
9554 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9557 Fixed BUG #519583. If a conditional block ended in a return/break
9558 statement inside a loop, it was not being considered part of the loop.
9560 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9562 2002-02-10 Karl Bongers <karl AT turbobit.com>
9565 Fixed up SDCDB debugger somewhat. Updated debugger/README
9566 with lots of comments and notes.
9568 * device/examples/test2.c:
