2158 * (struct resolvedIfx) is moved to gen.h and made public,
2159 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2160 * (aopForSym): added an optimization to directly store in stack of
2161 the operand of a SEND iCode,
2162 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2163 but as registers instead (AOP_REG) using the fReturnIdx array,
2164 * (pic16_freeAsmop): remove the freed register from the
2165 _G.sregsAlloc field,
2166 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2167 a compare of 'WREG',
2168 * (pic16_popGetTempRegCond): changed function prototype, now
2169 function takes also a bitVector argument v which holds the current
2170 set of registers that are allocated for stack access by aopForSym,
2171 registers allocated in aopForSym for accessing stack symbols are not
2172 any more part of the functions usedRegs field,
2173 * (genCall): some times aopOp is called for a stack variable to be
2174 send, aopForSym might perform the push, if this is true make sure
2175 that genCall doesn't push the variable twice by testing _G.resDirect,
2176 * (genFunction): changed testing for unspecified interrupt number
2177 from 256 to INTNO_UNSPEC,
2178 * modified selection scheme of frame pointer generation. Previously
2179 if function did use local registers a frame pointer was generated,
2180 now a frame pointer is generated only if function has arguments
2181 (that need PLUSW2 register access), or has stack arguments, or the
2182 compiler is not instructed to omit the frame pointer,
2183 * (genEndFunction): before restoring local registers that were saved
2184 in the function preamble, also restore the registers that *might*
2185 have been allocated for stack access,
2186 * (genRet): removed some old comments,
2187 * (genCmp, the active (RN's) version): added a call to the
2188 pic16_genCmp_special function to perform the compare with a more
2189 robust and optimized way,
2190 * (genInline): a feature has been added in inline code generation,
2191 which allows a wildcard variable substitution when writing inline
2192 assembly. Code is incomplete and experimental therefore undocumented,
2193 * (genCast): changed order of aopOp for result and right to allow
2194 aopForSym to directly load the result if possible,
2195 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2196 perform an optimized compare on some selected special occasions,
2197 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2198 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2199 generate an IVT any more,
2200 * src/pic16/main.c (pic16_optionsTable): added command line option
2202 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2203 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2205 * src/pic16/NOTES: Raphael Neider added in list of active developers
2206 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2207 jumptable_end to prevent bug #,
2208 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2209 inCond and outCond fields,
2210 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2211 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2212 turn off register spilling,
2213 * (packRegsForOneUse): synced with other ports' versions although it
2214 is not used currently,
2215 * (pic16_packRegisters): added an optimization while reading
2216 structure bitfields, some registers may be saved (malloc code is
2217 decreased by 80 bytes)
2219 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2221 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2222 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2223 this can be optimized more?
2225 2005-03-10 Raphael Neider <rneider AT web.de>
2227 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2228 genNearPointerGet): (hopefully) fixed access to bitfields via
2229 pointers (p->bitN = x; and x = p->bitN; failed)

2555 access stack and frame pointers. They are initially assigned to
2556 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2557 accessing SFRs. Updated all occurences of modification of stack or
2558 frame pointer in gen.c and pcode.c,
2559 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
2560 assigning of a literal value to pointers,

2863 Adding support for replacing ljmps with sjmps in jumptables
2864 generated for switch statements. For now you need to set the
2865 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2866 Now 4 algorithms for mcs51 jumptable generation are used:
2867 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2868 addresses loaded pc-relative for up to 112 cases and stack-pushing
2869 target addresses loaded with offset from dptr for up to 256 cases.

2902 functions, ctype functions and macros and some functions of the
2903 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2904 be extensively tested in the future. Standard disclaimer here.

2918 * (genCmp): experimental code for new genCmp which uses PIC18's
2919 special compare&skip instructions. Initial tests fail some times
2920 with variables grater than 1 byte in size, so new code is disabled,
2921 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2923 * (genCast): began a fix to optimize the casting of a bit to another
2924 bit, now assigning a bitfield to another bitfield will fail, sorry,

2938 registers when it shouldn't,
2939 * src/pic16/ralloc.c (allocReg): add preliminary support for
2940 supporting a limited set of temporary registers,
2942 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5950 loaded with the linker search paths (-L arguments) and the libraries
5951 to be linked with the current source (-l arguments). Changes
5952 currently will affect only the pic16 port.
5953 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5954 include path the port specific paths and port specific libraries,
5955 * gplink command now contains the $3 argument,
5956 * src/pic16/device.h,
5957 * src/pic16/device.c,: structure PIC_device is made public and
5958 renamed to PIC16_device, the same for variable Pics which is renamed

5973 Documenting changes from previous commits.
5974 * configure.in (version 1.56),
5975 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5976 when generating output files to configure the pic16 library,
5977 but now I've commented it out, since gputils aren't installed in the
5978 SF compile farm, so library won't compile
5980 * device/lib/Makefile.in (version 1.56): initially I've added in
5981 target 'all' the prerequestive 'model-pic16' so it compiled the
5982 pic16 library, but now I've commented it out for the same reasons
5984 * added targets 'model-pic16' and 'objects-pic16' to compile the
5986 * added target 'port-specific-objects-pic16' to handle the
5987 generated libraries and copy them into the build/ directory
5988 * added target 'clean-intermediate-pic16' to clean intermediate
5989 files into pic16 directory
5990 * in target 'installdirs' added line to create directory pic16 in

6239 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6241 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6242 (default behaviour).
6244 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6246 A python script to validate compiler diagnostic messages. It can be
6247 used to verify that sdcc complains about bad c source code and
6248 gives a good location of the error.
6249 * support/valdiag/Makefile,
6250 * support/valdiag/valdiag.py,
6251 * support/valdiag/tests/*

6268 Bug reported from Jesus Calvino-Fraga
6270 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6272 * sdcc.spec: updated
6273 * device/include/Makefile.in: don't install CVS directories
6274 * device/lib/Makefile.in: added removal of CVS directories after install
6275 * doc/Makefile: fixed install, added local_icons
6276 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6277 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6278 * src/ds390/gen.c (genRightShift): fixed bug #870788
6279 * src/SDCCast.c (decorateType): fixed bug #870781
6281 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6283 PIC16 port related changes:
6284 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6285 added variable stackPos,
6287 * gen.c: genCall, assignResultValue: added support for
6288 pushing/retrieving function parameters to/from stack,
6289 genFunction,genEndFunction: setup stack frame for the
6291 genAddrOf: will be changed according to bug 863624
6293 * added files genutils.c and genutils.h which contain gen*
6294 debugged and optimised functions extracted from gen.c
6296 * glue.c: added variable 'externs' which holds extern symbols,
6297 pic16emitRegularMap: is modified to properly handle relocatable
6298 symbols under the new scheme,
6299 pic16createInterruptVect: is modified
6300 pic16printPublics: is modified to emit 'global' assembler directives,
6301 added pic16_printExterns to print extern symbols,
6302 pic16glue: initializes stack/frame pointer in the beginning of
6303 the assembly output. Temporary hack, will be corrected later,
6304 because gplink yet does not support stack and SDCC does not
6305 yet support a type of crt0.o object to create the final binary.
6307 * Removed many lines that contain 8051 legacy code.
6308 * The code is finally placed under a 'code' directive.
6309 * Added port specific options.
6311 * _process_pragma: simplified since now we do not need *special*
6312 include file to define SFR registers. But a separate header
6313 will be needed. This will be developed later.
6314 * _pic16_parseOptions: added, parses port specific options:
6315 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6316 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6317 --preplace-udata-with=
6319 * _pic16_setDefaultOptions: modified to initialize section names,
6320 but hack is temporarly out of order since it needs improvement.
6321 * _pic16_genAssemblerPreamble: configuration words are emitted by
6322 their address instead of their name. This part is incomplete and
6323 supports only the 18Fxx2 devices. Other devices will emit an error
6324 during assembly since they do not contain the same set of config
6326 * _pic16_genIVT: is modified,
6328 * pcode.c: added definitions for some hardware registers that are needed
6330 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6331 All PCI entries are updated. Now LFSR is supported.
6332 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6333 * added pic16_newpCodeOpLit2 to support instructions with
6334 two literal arguments
6335 * pic16_pCode2str: corrected code that emits assembler instructions
6336 with two literal operands and those that have an access bit modifier
6337 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6338 this fixes a bug which caused some labels to be lost, when an
6339 assembler directive was added, i.e. banksel,
6340 * pic16_FixRegisterBanking: improved logic that causes the insertion
6342 * InlineFunction: functions that are called once, are not any more
6343 inlined. This can be a port option in the future,
6345 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6347 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6348 hold the corresponding uninitialized symbols,
6349 * pic16_allocProcessorRegister: registers have explicit marked the
6351 * pic16_allocInternalRegister: registers are explicit marked as
6353 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6354 processing list, so bit registers were lost,
6357 * ralloc.h: added field 'accessBank' and original symbol operand
6358 in register definition,
6359 * removed the field isMapped from register definition,
6361 ** Several functions have been removed from various sources:
6362 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6363 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6364 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6365 pic16_assignRelocatableRegisters
6367 ** others have been introduced:
6368 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6369 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6371 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6373 * support/scripts/inc2h.pl: changed definition of BIT_AT
6374 to emit 'sbit at' instead of 'bit at'. This was a request.
6376 PIC16 port related preliminary changes:
6377 * gen.c: prefixed function popRegFromString with
6378 pic16_ and all references to it corrected
6379 * pcode.c: all pic16_pc_* hardware registers prefixed
6380 with underscore (_),
6381 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6382 * ralloc.c: newReg(): when register is REG_SFR then
6383 set address to rIdx,
6384 pic16_allocProcessorRegister(): marks register wasUsed=0
6385 pic16_writeUsedRegs(): added a call to assign processor
6386 registers via pic16_assignFixedRegisters
6388 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6390 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6391 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6392 variables in unused register banks. Also the SSEG is placed
6393 wherever there is enough space for it, and IDATA can be anywhere
6394 in internal RAM. For now compile using -Wl-Y[stack_size].
6395 The mem file is different for this option as well, since it
6396 makes no sense of talking about DSEG lenght.
6398 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6400 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6401 in certain cases, e.g. when ROM assignment, patch provided
6402 from Albert den Haan.
6404 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7406 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7407 fetching of the pointer
7408 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7409 copied from genNearPointerSet()
7410 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7411 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7412 If they pop r0/r1 they must be called in the opposite order than aopOp().
7413 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7414 (resp. --stack-auto), prepared for --xstack

7425 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7427 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7428 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7429 type for bits was changed. It resulted in bit variables becoming
7430 global, which is not permitted in PIC 14 assembly output.
7432 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7434 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7447 A few small changes that speed up the peephole optimizer.
7451 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7453 Try to make the peephole optimizer smarter by maintaining
7454 an association between the assembly source code and the
7455 iCodes that originated them. Put this information to use
7456 with a new peephole rule condition "notVolatile" so that
7457 the rules can be aggressive yet still safe.
7462 * src/mcs51/peeph.def
7464 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7468 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7469 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7470 if the left or right operand symbols have the accuse flag set.
7472 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7474 Changed the type of the result of the ! (NOT) operator to char;
7475 previously it returned the same type as the source. This allows
7476 us to eliminate all the genFloatNot functions (all of its target
7477 implementations were very buggy) since !float can use the same
7480 * src/SDCCicode.c (ast2iCode): ! returns char

7482 * src/ds390/gen.c (genNot, genNotFloat),
7483 * src/z80/gen.c (genNot, genNotFloat),
7484 * src/pic/gen.c (genNot, genNotFloat),

7487 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7489 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7490 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7491 during interrupts. Ensure WSAVE is located at a shared bank address.
7492 2. Fixed page selection in some places
7493 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7494 the registers name strings.
7495 4. Fixed "signed / unsigned compare" compiler warnings.
7496 5. The PIC port manages its own allocation of the general purpose
7497 registers, but makes no attempt to reuse them. As a result when
7498 compiling it soon runs out of general purpose registers. Some
7499 additional code was added to the files pcode.c and device.c to walk
7500 through the function call tree and rename the registers so that they
7510 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7511 genPlus() & genMinus() when the result is the same as left or right

7517 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7519 Made bitfield a distinct type from bit so that bitfields
7520 convert as per ANSI C and bits retain their traditional
7521 boolean style behaviour. Implemented bitfield support in
7529 * src/ds390/gen.c: bit v bitfield split
7530 * src/z80/gen.c: New support for bitfields
7531 * support/regression/tests/bitfields.c: reenabled z80,
7534 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7536 Rules 246.x, 247.x relate to bitfields, the others speed up
7537 access to xdata mapped I/O devices.
7539 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7541 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7543 Cleaned up genPackBits and genUnpackBits and added two helper
7544 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7545 for literal assignments in genPackBits (thanks to Frieder for
7551 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7553 Fixed bug #748310 (pointer to function type mishandled when the
7554 function name is omitted). Also fixed a SIGSEGV when a function
7555 attribute (reentrant, etc) is used on a non-function or on a
7556 function but misplaced before the parameter list.
7558 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7560 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7561 * support/Util/SDCCerr.h,
7562 * support/Util/SDCCerr.c: Added func attr misuse error msg

7583 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7585 Made the constant following the "interrupt" keyword optional. If
7586 omitted, the function will not automatically be given an entry
7587 in the interrupt vector table (similar to #pragma NOIV, but
7588 less syntacticly kludgy). The interrupt number is also now
7589 range checked. Also fixed a bug in the high order bit example

7605 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7607 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7608 be re-activated by defining REDUCE_LITERALS)
7609 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7610 unsigned, but are signed by default
7611 * src/SDCCval.c (constVal): rearranged
7612 * src/SDCCval.c (valMod): preliminary fix
7613 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8119 added if/endif conditional macros to remove options help
8120 messages from optionsTable when a port is not configured, added
8121 support for the PIc16 port in the ports table, when executing
8122 the compiler with no port specified on command line, a default
8123 port is selected with the new macro DEFAULT_PORT which is
8124 defined in port.h, in setDefaultOptions() linkOptions is removed
8125 from initialization assignment, since now it is a set,
8126 parseCmdLine uses setParseWithComma for linkOptions, in
8127 linkEdit() linkOptions are accessed with new function indexSet()
8128 which returns the i'th item of a set variable. See SDCCset.c, in
8129 linkEdit() when calling buildCmdLine(), added linkOptions as
8130 last argument. Now users can pass arguments to gplink via the
8131 -Wl option, main() uses pic16glue() to glue up pic16 programs

8145 gpasm complaining and test the linkage with gplink, _linkCmd and
8146 _asmCmd changed to be more gplink and gpasm friendly
8147 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8148 produced an error when parsed, peep rule 12 is added to utilize
8149 movff, but it is commented out since the pCode does not support
8150 yet a command with 2 address arguments
8152 2003-05-18 <johan AT balder>
8154 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8179 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8181 2003-05-11 Borut Razem <borut.razem AT siol.net>
8183 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9191 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9192 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9193 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9195 2003-01-04 <johan AT balder>
9197 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9199 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9200 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9202 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9212 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9213 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9215 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9217 * in \sdcc\as\mcs51\ changed these files in order to create an
9218 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9219 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9220 following files to include the previous two files: aslink.dsp,
9221 Makefile.aslink, Makefile.bcc, and Makefile.in.
9223 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9224 .adb instead of .cdb
9226 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9228 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9229 value from option --iram-size.
9231 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9233 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9236 2002-09-18 <wiml AT hhhh.org>
9238 * SDCClrange.h: exposed setFromRange() and setToRange()
9239 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9240 packRegsForAccUse() (bug 542397)
9241 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9242 multiple times and emitting the fetch operations more than once
9243 added aopGetUsesAcc() function to allow binary operators to
9244 fetch their operands in the correct order; made genMinus() emit
9245 compact code for X = LITERAL - Y
9247 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9248 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9249 sprintf() in line 1267.
9251 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9252 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9255 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9256 Changes to aslink (All the changes are marked with 'JCF'):
9258 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9261 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9262 area BSEG. Also moves, if possible, the DATA area down into the internal
9263 ram so more space is available.
9265 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9268 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9269 not bytes. Function summary() which creates a memory usage summary
9270 file with extension .mem. Reports of overlaping stack and small stack
9271 size. If the space for the stack is less than 16 bytes aslink trows a
9274 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9275 the 8051. Option 'y' for memory summary output file.
9277 Changes to sdcc (All the changes are marked with 'JCF'):
9279 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9281 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9282 overlaying area for it (uses RegBankUsed[4]).
9284 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9285 bank zero as used by default. By default aslink locates the stack
9286 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9287 the creation of the .mem file. Delegates the allocation of data area
9288 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9289 the begining of the stack area to aslink.
9291 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9292 glue() in SDCCglue.c creates an area for it.
9294 2002-09-03 Borut Razem <borut.razem AT siol.net>
9295 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9296 sdcc/src/pic/glue.c:
9297 introduced atexit() handler for teporay files removal in case of
9298 errors, assertions, ...
9300 2002-08-29 Borut Razem <borut.razem AT siol.net>
9301 * sdcc/support/cpp2/auto-host_vc_in.h:
9302 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9303 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9304 Maybe there is a similar problem with BORLANDC? It should be checked!
9306 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9307 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9308 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9309 was not executed, and the compiler (cl) launched a warning:
9310 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9312 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9313 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9315 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9316 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9318 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9319 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9320 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9321 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9322 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9323 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9324 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9325 - added Release configuration in VS projects
9326 - review of compiler an linker options
9327 - VC .exe files are generated in bin_vc directory, not to interfere
9328 with binaries generated from other projects (cygwin, mingw, bcc ...)
9330 * sdcc/src/yacc.dsp: added
9332 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9333 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9334 and insert the version number definitions from .version
9336 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9338 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9339 added - genarate auto-host.h using auto-host_vc_in.h as template
9342 removed from CVS, generated automatically
9344 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9345 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9347 2002-08-11 Borut Razem <borut.razem AT siol.net>
9348 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9350 2002-08-10 Borut Razem <borut.razem AT siol.net>
9351 * src/SDCCmain.c (main):
9352 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9353 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9354 The consequence was that some temporary files were not removed.
9357 unification of code in functions tempfilename() and tempfile():
9358 function tempnam() is defined in Visual Studio 6.0 and .NET
9360 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9362 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9363 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9364 - removed compiler command line option /WX: Treats all warnings as errors
9365 - update a list of source files, included into the project
9367 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9368 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9369 changed project type to Generic Project so that can be correcly converted to VS.NET project
9371 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9373 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9375 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9377 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9378 added return 0 statements after assert() to make compiler happy
9380 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9381 added newline in the def file to keep MSC compiler satisfied
9383 * sdcc/src/z80/gen.c:
9384 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9385 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9386 - solved MSC error in function aopDump()
9388 * sdcc_vc.h: define PREFIX as "\\sdcc"
9390 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9391 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9393 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9394 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9395 - Rewrote the register banking algorithm.
9396 - Added pCode live-range analysis to registers (for now, only non-used and
9397 singly-used registers optimized away)
9399 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9401 * 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.

9430 2002-03-28 Johan Knol <johan AT balder>
9432 * src/SDCCval.c: fixed bug #532436
9434 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9436 Added "char *Processor" field to the port structure.
9439 Added -p option. Allows port dependent processor to be specified.
9442 Initialized the new field char *Processor field to NULL in all ports
9445 Compiler generated registers for interrupt context saving
9446 were not getting allocated.
9448 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9451 Fixed left shift. Will promote the left side of a left shift
9452 if a) left shifting more than size of operand or b) when assigned
9453 to something size > size of left side
9455 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9457 tons of changes. Register allocation has been
9458 rewritten. Added customization for the various PICs. Flow
9459 analysis is restructured. ...
9465 Added. device.c is a PIC port hack to accomodate variations

9566 Previous fix was not good. basic blocks that have "break" or "return" are
9567 not really partof a loop , but live ranges used in these blocks should
9568 be live thru the entire loop, so set partOfLoop but don't add them to
