2160 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2161 prevent compiler warning
2163 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2165 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2166 moved to level 0 and declared as static. Also they are explicit
2167 placed in access bank. This was necessery because some times they
2168 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2169 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2170 optimizations. Currently only compare to unsigned char is implemented,
2171 * src/pic16/gen.c: added fReturnIdx array,
2172 * (struct resolvedIfx) is moved to gen.h and made public,
2173 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2174 * (aopForSym): added an optimization to directly store in stack of
2175 the operand of a SEND iCode,
2176 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2177 but as registers instead (AOP_REG) using the fReturnIdx array,
2178 * (pic16_freeAsmop): remove the freed register from the
2179 _G.sregsAlloc field,
2180 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2181 a compare of 'WREG',
2182 * (pic16_popGetTempRegCond): changed function prototype, now
2183 function takes also a bitVector argument v which holds the current
2184 set of registers that are allocated for stack access by aopForSym,
2185 registers allocated in aopForSym for accessing stack symbols are not
2186 any more part of the functions usedRegs field,
2187 * (genCall): some times aopOp is called for a stack variable to be
2188 send, aopForSym might perform the push, if this is true make sure
2189 that genCall doesn't push the variable twice by testing _G.resDirect,
2190 * (genFunction): changed testing for unspecified interrupt number
2191 from 256 to INTNO_UNSPEC,
2192 * modified selection scheme of frame pointer generation. Previously
2193 if function did use local registers a frame pointer was generated,
2194 now a frame pointer is generated only if function has arguments
2195 (that need PLUSW2 register access), or has stack arguments, or the
2196 compiler is not instructed to omit the frame pointer,
2197 * (genEndFunction): before restoring local registers that were saved
2198 in the function preamble, also restore the registers that *might*
2199 have been allocated for stack access,
2200 * (genRet): removed some old comments,
2201 * (genCmp, the active (RN's) version): added a call to the
2202 pic16_genCmp_special function to perform the compare with a more
2203 robust and optimized way,
2204 * (genInline): a feature has been added in inline code generation,
2205 which allows a wildcard variable substitution when writing inline
2206 assembly. Code is incomplete and experimental therefore undocumented,
2207 * (genCast): changed order of aopOp for result and right to allow
2208 aopForSym to directly load the result if possible,
2209 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2210 perform an optimized compare on some selected special occasions,
2211 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2212 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2213 generate an IVT any more,
2214 * src/pic16/main.c (pic16_optionsTable): added command line option
2216 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2217 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2219 * src/pic16/NOTES: Raphael Neider added in list of active developers
2220 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2221 jumptable_end to prevent bug #,
2222 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2223 inCond and outCond fields,
2224 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2225 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2226 turn off register spilling,
2227 * (packRegsForOneUse): synced with other ports' versions although it
2228 is not used currently,
2229 * (pic16_packRegisters): added an optimization while reading
2230 structure bitfields, some registers may be saved (malloc code is
2231 decreased by 80 bytes)
2233 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2235 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2236 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2237 this can be optimized more?
2239 2005-03-10 Raphael Neider <rneider AT web.de>
2241 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2242 genNearPointerGet): (hopefully) fixed access to bitfields via
2243 pointers (p->bitN = x; and x = p->bitN; failed)

2569 access stack and frame pointers. They are initially assigned to
2570 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2571 accessing SFRs. Updated all occurences of modification of stack or
2572 frame pointer in gen.c and pcode.c,
2573 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
2574 assigning of a literal value to pointers,

2878 generated for switch statements. For now you need to set the
2879 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2880 Now 4 algorithms for mcs51 jumptable generation are used:
2881 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2915 * added libc directory. The current version of LibC contains string
2916 functions, ctype functions and macros and some functions of the
2917 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2918 be extensively tested in the future. Standard disclaimer here.

2931 * (pic16_storeForReturn): optimized return of 0,
2932 * (genCmp): experimental code for new genCmp which uses PIC18's
2933 special compare&skip instructions. Initial tests fail some times
2934 with variables grater than 1 byte in size, so new code is disabled,
2935 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2937 * (genCast): began a fix to optimize the casting of a bit to another
2938 bit, now assigning a bitfield to another bitfield will fail, sorry,

2952 registers when it shouldn't,
2953 * src/pic16/ralloc.c (allocReg): add preliminary support for
2954 supporting a limited set of temporary registers,
2956 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5964 loaded with the linker search paths (-L arguments) and the libraries
5965 to be linked with the current source (-l arguments). Changes
5966 currently will affect only the pic16 port.
5967 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5968 include path the port specific paths and port specific libraries,
5969 * gplink command now contains the $3 argument,
5970 * src/pic16/device.h,

5987 Documenting changes from previous commits.
5988 * configure.in (version 1.56),
5989 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5990 when generating output files to configure the pic16 library,
5991 but now I've commented it out, since gputils aren't installed in the
5992 SF compile farm, so library won't compile
5994 * device/lib/Makefile.in (version 1.56): initially I've added in
5995 target 'all' the prerequestive 'model-pic16' so it compiled the
5996 pic16 library, but now I've commented it out for the same reasons
5998 * added targets 'model-pic16' and 'objects-pic16' to compile the
6000 * added target 'port-specific-objects-pic16' to handle the
6001 generated libraries and copy them into the build/ directory
6002 * added target 'clean-intermediate-pic16' to clean intermediate
6003 files into pic16 directory
6004 * in target 'installdirs' added line to create directory pic16 in

6026 option so that it actually works. Made it specific to the z80, since
6027 the gbz80 doesn't have these kinds of I/O ports.
6029 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6253 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6255 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6256 (default behaviour).
6258 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6260 A python script to validate compiler diagnostic messages. It can be
6261 used to verify that sdcc complains about bad c source code and
6262 gives a good location of the error.
6263 * support/valdiag/Makefile,
6264 * support/valdiag/valdiag.py,
6265 * support/valdiag/tests/*

6282 Bug reported from Jesus Calvino-Fraga
6284 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6286 * sdcc.spec: updated
6287 * device/include/Makefile.in: don't install CVS directories
6288 * device/lib/Makefile.in: added removal of CVS directories after install
6289 * doc/Makefile: fixed install, added local_icons
6290 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6291 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6292 * src/ds390/gen.c (genRightShift): fixed bug #870788
6293 * src/SDCCast.c (decorateType): fixed bug #870781
6295 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6297 PIC16 port related changes:
6298 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6299 added variable stackPos,
6301 * gen.c: genCall, assignResultValue: added support for
6302 pushing/retrieving function parameters to/from stack,
6303 genFunction,genEndFunction: setup stack frame for the
6305 genAddrOf: will be changed according to bug 863624
6307 * added files genutils.c and genutils.h which contain gen*
6308 debugged and optimised functions extracted from gen.c
6310 * glue.c: added variable 'externs' which holds extern symbols,
6311 pic16emitRegularMap: is modified to properly handle relocatable
6312 symbols under the new scheme,
6313 pic16createInterruptVect: is modified
6314 pic16printPublics: is modified to emit 'global' assembler directives,
6315 added pic16_printExterns to print extern symbols,
6316 pic16glue: initializes stack/frame pointer in the beginning of
6317 the assembly output. Temporary hack, will be corrected later,
6318 because gplink yet does not support stack and SDCC does not
6319 yet support a type of crt0.o object to create the final binary.
6321 * Removed many lines that contain 8051 legacy code.
6322 * The code is finally placed under a 'code' directive.
6323 * Added port specific options.
6325 * _process_pragma: simplified since now we do not need *special*
6326 include file to define SFR registers. But a separate header
6327 will be needed. This will be developed later.
6328 * _pic16_parseOptions: added, parses port specific options:
6329 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6330 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6331 --preplace-udata-with=
6333 * _pic16_setDefaultOptions: modified to initialize section names,
6334 but hack is temporarly out of order since it needs improvement.
6335 * _pic16_genAssemblerPreamble: configuration words are emitted by
6336 their address instead of their name. This part is incomplete and
6337 supports only the 18Fxx2 devices. Other devices will emit an error
6338 during assembly since they do not contain the same set of config
6340 * _pic16_genIVT: is modified,
6342 * pcode.c: added definitions for some hardware registers that are needed
6344 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6345 All PCI entries are updated. Now LFSR is supported.
6346 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6347 * added pic16_newpCodeOpLit2 to support instructions with
6348 two literal arguments
6349 * pic16_pCode2str: corrected code that emits assembler instructions
6350 with two literal operands and those that have an access bit modifier
6351 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6352 this fixes a bug which caused some labels to be lost, when an
6353 assembler directive was added, i.e. banksel,
6354 * pic16_FixRegisterBanking: improved logic that causes the insertion
6356 * InlineFunction: functions that are called once, are not any more
6357 inlined. This can be a port option in the future,
6359 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6361 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6362 hold the corresponding uninitialized symbols,
6363 * pic16_allocProcessorRegister: registers have explicit marked the
6365 * pic16_allocInternalRegister: registers are explicit marked as
6367 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6368 processing list, so bit registers were lost,
6371 * ralloc.h: added field 'accessBank' and original symbol operand
6372 in register definition,
6373 * removed the field isMapped from register definition,
6375 ** Several functions have been removed from various sources:
6376 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6377 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6378 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6379 pic16_assignRelocatableRegisters
6381 ** others have been introduced:
6382 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6383 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6385 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6387 * support/scripts/inc2h.pl: changed definition of BIT_AT
6388 to emit 'sbit at' instead of 'bit at'. This was a request.
6390 PIC16 port related preliminary changes:
6391 * gen.c: prefixed function popRegFromString with
6392 pic16_ and all references to it corrected
6393 * pcode.c: all pic16_pc_* hardware registers prefixed
6394 with underscore (_),
6395 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6396 * ralloc.c: newReg(): when register is REG_SFR then
6397 set address to rIdx,
6398 pic16_allocProcessorRegister(): marks register wasUsed=0
6399 pic16_writeUsedRegs(): added a call to assign processor
6400 registers via pic16_assignFixedRegisters
6402 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6404 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6405 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6406 variables in unused register banks. Also the SSEG is placed
6407 wherever there is enough space for it, and IDATA can be anywhere
6408 in internal RAM. For now compile using -Wl-Y[stack_size].
6409 The mem file is different for this option as well, since it
6410 makes no sense of talking about DSEG lenght.
6412 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6414 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6415 in certain cases, e.g. when ROM assignment, patch provided
6416 from Albert den Haan.
6418 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7420 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7421 fetching of the pointer
7422 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7423 copied from genNearPointerSet()
7424 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7425 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7441 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7442 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7443 type for bits was changed. It resulted in bit variables becoming
7444 global, which is not permitted in PIC 14 assembly output.
7446 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7461 A few small changes that speed up the peephole optimizer.
7465 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7467 Try to make the peephole optimizer smarter by maintaining
7468 an association between the assembly source code and the
7469 iCodes that originated them. Put this information to use
7470 with a new peephole rule condition "notVolatile" so that
7471 the rules can be aggressive yet still safe.
7476 * src/mcs51/peeph.def
7478 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7482 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7483 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7484 if the left or right operand symbols have the accuse flag set.
7486 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7488 Changed the type of the result of the ! (NOT) operator to char;
7489 previously it returned the same type as the source. This allows
7490 us to eliminate all the genFloatNot functions (all of its target
7491 implementations were very buggy) since !float can use the same
7494 * src/SDCCicode.c (ast2iCode): ! returns char

7503 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7504 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7505 during interrupts. Ensure WSAVE is located at a shared bank address.
7506 2. Fixed page selection in some places
7507 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7508 the registers name strings.
7509 4. Fixed "signed / unsigned compare" compiler warnings.
7510 5. The PIC port manages its own allocation of the general purpose
7511 registers, but makes no attempt to reuse them. As a result when
7512 compiling it soon runs out of general purpose registers. Some
7513 additional code was added to the files pcode.c and device.c to walk
7514 through the function call tree and rename the registers so that they
7524 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7525 genPlus() & genMinus() when the result is the same as left or right

7531 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7533 Made bitfield a distinct type from bit so that bitfields
7534 convert as per ANSI C and bits retain their traditional
7535 boolean style behaviour. Implemented bitfield support in
7543 * src/ds390/gen.c: bit v bitfield split
7544 * src/z80/gen.c: New support for bitfields
7545 * support/regression/tests/bitfields.c: reenabled z80,
7548 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7550 Rules 246.x, 247.x relate to bitfields, the others speed up
7551 access to xdata mapped I/O devices.
7553 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7555 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7557 Cleaned up genPackBits and genUnpackBits and added two helper
7558 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7559 for literal assignments in genPackBits (thanks to Frieder for
7565 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7567 Fixed bug #748310 (pointer to function type mishandled when the
7568 function name is omitted). Also fixed a SIGSEGV when a function
7569 attribute (reentrant, etc) is used on a non-function or on a
7570 function but misplaced before the parameter list.
7572 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7574 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7575 * support/Util/SDCCerr.h,

7597 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7599 Made the constant following the "interrupt" keyword optional. If
7600 omitted, the function will not automatically be given an entry
7601 in the interrupt vector table (similar to #pragma NOIV, but
7602 less syntacticly kludgy). The interrupt number is also now
7603 range checked. Also fixed a bug in the high order bit example

7619 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7621 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7622 be re-activated by defining REDUCE_LITERALS)
7623 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7624 unsigned, but are signed by default
7625 * src/SDCCval.c (constVal): rearranged
7626 * src/SDCCval.c (valMod): preliminary fix
7627 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8132 * src/SDCCmain.c: linkOptions is changed to set *,
8133 added if/endif conditional macros to remove options help
8134 messages from optionsTable when a port is not configured, added
8135 support for the PIc16 port in the ports table, when executing
8136 the compiler with no port specified on command line, a default
8137 port is selected with the new macro DEFAULT_PORT which is
8138 defined in port.h, in setDefaultOptions() linkOptions is removed
8139 from initialization assignment, since now it is a set,
8140 parseCmdLine uses setParseWithComma for linkOptions, in
8141 linkEdit() linkOptions are accessed with new function indexSet()
8142 which returns the i'th item of a set variable. See SDCCset.c, in
8143 linkEdit() when calling buildCmdLine(), added linkOptions as
8144 last argument. Now users can pass arguments to gplink via the
8145 -Wl option, main() uses pic16glue() to glue up pic16 programs

8158 * src/pic16/main.c: __config directives are commented out to stop
8159 gpasm complaining and test the linkage with gplink, _linkCmd and
8160 _asmCmd changed to be more gplink and gpasm friendly
8161 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8162 produced an error when parsed, peep rule 12 is added to utilize
8163 movff, but it is commented out since the pCode does not support
8164 yet a command with 2 address arguments
8166 2003-05-18 <johan AT balder>
8168 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8187 Fixed so you can set breakpoints prior to run, run does not stop
8188 on entry now. Add tbreak. Other enhancements and fixes for use
8191 2003-05-12 Borut Razem <borut.razem AT siol.net>
8193 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8195 2003-05-11 Borut Razem <borut.razem AT siol.net>
8197 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8198 the path of bin directory, so that PATH is the only env. variable, which has to be set
8199 in case of standard installation.
8200 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9203 * src/SDCCicode.c: fixed array add
9205 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9206 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9207 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9209 2003-01-04 <johan AT balder>
9211 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9213 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9226 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9227 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9229 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9231 * in \sdcc\as\mcs51\ changed these files in order to create an
9232 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9233 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9234 following files to include the previous two files: aslink.dsp,
9235 Makefile.aslink, Makefile.bcc, and Makefile.in.
9237 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9238 .adb instead of .cdb
9240 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9242 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9243 value from option --iram-size.
9245 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9247 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9250 2002-09-18 <wiml AT hhhh.org>
9252 * SDCClrange.h: exposed setFromRange() and setToRange()
9253 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9254 packRegsForAccUse() (bug 542397)
9255 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9256 multiple times and emitting the fetch operations more than once
9257 added aopGetUsesAcc() function to allow binary operators to
9258 fetch their operands in the correct order; made genMinus() emit
9259 compact code for X = LITERAL - Y
9261 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9262 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9263 sprintf() in line 1267.
9265 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9266 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9269 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9270 Changes to aslink (All the changes are marked with 'JCF'):
9272 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9275 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9276 area BSEG. Also moves, if possible, the DATA area down into the internal
9277 ram so more space is available.
9279 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9282 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9283 not bytes. Function summary() which creates a memory usage summary
9284 file with extension .mem. Reports of overlaping stack and small stack
9285 size. If the space for the stack is less than 16 bytes aslink trows a
9288 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9289 the 8051. Option 'y' for memory summary output file.
9291 Changes to sdcc (All the changes are marked with 'JCF'):
9293 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9295 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9296 overlaying area for it (uses RegBankUsed[4]).
9298 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9299 bank zero as used by default. By default aslink locates the stack
9300 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9301 the creation of the .mem file. Delegates the allocation of data area
9302 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9303 the begining of the stack area to aslink.
9305 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9306 glue() in SDCCglue.c creates an area for it.
9308 2002-09-03 Borut Razem <borut.razem AT siol.net>
9309 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9310 sdcc/src/pic/glue.c:
9311 introduced atexit() handler for teporay files removal in case of
9312 errors, assertions, ...
9314 2002-08-29 Borut Razem <borut.razem AT siol.net>
9315 * sdcc/support/cpp2/auto-host_vc_in.h:
9316 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9317 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9318 Maybe there is a similar problem with BORLANDC? It should be checked!
9320 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9321 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9322 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9323 was not executed, and the compiler (cl) launched a warning:
9324 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9326 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9327 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9329 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9330 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9332 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9333 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9334 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9335 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9336 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9337 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9338 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9339 - added Release configuration in VS projects
9340 - review of compiler an linker options
9341 - VC .exe files are generated in bin_vc directory, not to interfere
9342 with binaries generated from other projects (cygwin, mingw, bcc ...)
9344 * sdcc/src/yacc.dsp: added
9346 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9347 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9348 and insert the version number definitions from .version
9350 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9352 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9353 added - genarate auto-host.h using auto-host_vc_in.h as template
9356 removed from CVS, generated automatically
9358 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9359 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9361 2002-08-11 Borut Razem <borut.razem AT siol.net>
9362 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9364 2002-08-10 Borut Razem <borut.razem AT siol.net>
9365 * src/SDCCmain.c (main):
9366 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9367 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9368 The consequence was that some temporary files were not removed.
9371 unification of code in functions tempfilename() and tempfile():
9372 function tempnam() is defined in Visual Studio 6.0 and .NET
9374 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9376 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9377 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9378 - removed compiler command line option /WX: Treats all warnings as errors
9379 - update a list of source files, included into the project
9381 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9382 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9383 changed project type to Generic Project so that can be correcly converted to VS.NET project
9385 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9387 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9389 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9391 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9392 added return 0 statements after assert() to make compiler happy
9394 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9395 added newline in the def file to keep MSC compiler satisfied
9397 * sdcc/src/z80/gen.c:
9398 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9399 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9400 - solved MSC error in function aopDump()
9402 * sdcc_vc.h: define PREFIX as "\\sdcc"
9404 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9405 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9407 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9408 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9409 - Rewrote the register banking algorithm.
9410 - Added pCode live-range analysis to registers (for now, only non-used and
9411 singly-used registers optimized away)
9413 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9415 * 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.

9444 2002-03-28 Johan Knol <johan AT balder>
9446 * src/SDCCval.c: fixed bug #532436
9448 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9450 Added "char *Processor" field to the port structure.
9453 Added -p option. Allows port dependent processor to be specified.
9456 Initialized the new field char *Processor field to NULL in all ports
9459 Compiler generated registers for interrupt context saving
9460 were not getting allocated.
9462 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9465 Fixed left shift. Will promote the left side of a left shift
9466 if a) left shifting more than size of operand or b) when assigned
9467 to something size > size of left side
9469 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9471 tons of changes. Register allocation has been
9472 rewritten. Added customization for the various PICs. Flow
9473 analysis is restructured. ...
9479 Added. device.c is a PIC port hack to accomodate variations

9579 * sdcc/src/SDCCloop.c:
9580 Previous fix was not good. basic blocks that have "break" or "return" are
9581 not really partof a loop , but live ranges used in these blocks should
9582 be live thru the entire loop, so set partOfLoop but don't add them to
