2159 * src/pic16/gen.c: added fReturnIdx array,
2160 * (struct resolvedIfx) is moved to gen.h and made public,
2161 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2162 * (aopForSym): added an optimization to directly store in stack of
2163 the operand of a SEND iCode,
2164 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2165 but as registers instead (AOP_REG) using the fReturnIdx array,
2166 * (pic16_freeAsmop): remove the freed register from the
2167 _G.sregsAlloc field,
2168 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2169 a compare of 'WREG',
2170 * (pic16_popGetTempRegCond): changed function prototype, now
2171 function takes also a bitVector argument v which holds the current
2172 set of registers that are allocated for stack access by aopForSym,
2173 registers allocated in aopForSym for accessing stack symbols are not
2174 any more part of the functions usedRegs field,
2175 * (genCall): some times aopOp is called for a stack variable to be
2176 send, aopForSym might perform the push, if this is true make sure
2177 that genCall doesn't push the variable twice by testing _G.resDirect,
2178 * (genFunction): changed testing for unspecified interrupt number
2179 from 256 to INTNO_UNSPEC,
2180 * modified selection scheme of frame pointer generation. Previously
2181 if function did use local registers a frame pointer was generated,
2182 now a frame pointer is generated only if function has arguments
2183 (that need PLUSW2 register access), or has stack arguments, or the
2184 compiler is not instructed to omit the frame pointer,
2185 * (genEndFunction): before restoring local registers that were saved
2186 in the function preamble, also restore the registers that *might*
2187 have been allocated for stack access,
2188 * (genRet): removed some old comments,
2189 * (genCmp, the active (RN's) version): added a call to the
2190 pic16_genCmp_special function to perform the compare with a more
2191 robust and optimized way,
2192 * (genInline): a feature has been added in inline code generation,
2193 which allows a wildcard variable substitution when writing inline
2194 assembly. Code is incomplete and experimental therefore undocumented,
2195 * (genCast): changed order of aopOp for result and right to allow
2196 aopForSym to directly load the result if possible,
2197 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2198 perform an optimized compare on some selected special occasions,
2199 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2200 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2201 generate an IVT any more,
2202 * src/pic16/main.c (pic16_optionsTable): added command line option
2204 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2205 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2207 * src/pic16/NOTES: Raphael Neider added in list of active developers
2208 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2209 jumptable_end to prevent bug #,
2210 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2211 inCond and outCond fields,
2212 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2213 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2214 turn off register spilling,
2215 * (packRegsForOneUse): synced with other ports' versions although it
2216 is not used currently,
2217 * (pic16_packRegisters): added an optimization while reading
2218 structure bitfields, some registers may be saved (malloc code is
2219 decreased by 80 bytes)
2221 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2223 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2224 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2225 this can be optimized more?
2227 2005-03-10 Raphael Neider <rneider AT web.de>
2229 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2230 genNearPointerGet): (hopefully) fixed access to bitfields via

2557 access stack and frame pointers. They are initially assigned to
2558 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2559 accessing SFRs. Updated all occurences of modification of stack or
2560 frame pointer in gen.c and pcode.c,

2866 generated for switch statements. For now you need to set the
2867 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2868 Now 4 algorithms for mcs51 jumptable generation are used:
2869 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2904 functions, ctype functions and macros and some functions of the
2905 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2906 be extensively tested in the future. Standard disclaimer here.

2920 * (genCmp): experimental code for new genCmp which uses PIC18's
2921 special compare&skip instructions. Initial tests fail some times
2922 with variables grater than 1 byte in size, so new code is disabled,
2923 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2925 * (genCast): began a fix to optimize the casting of a bit to another
2926 bit, now assigning a bitfield to another bitfield will fail, sorry,

2941 * src/pic16/ralloc.c (allocReg): add preliminary support for
2942 supporting a limited set of temporary registers,

5952 loaded with the linker search paths (-L arguments) and the libraries
5953 to be linked with the current source (-l arguments). Changes
5954 currently will affect only the pic16 port.
5955 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5956 include path the port specific paths and port specific libraries,
5957 * gplink command now contains the $3 argument,
5958 * src/pic16/device.h,
5959 * src/pic16/device.c,: structure PIC_device is made public and

5975 Documenting changes from previous commits.
5976 * configure.in (version 1.56),
5977 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5978 when generating output files to configure the pic16 library,
5979 but now I've commented it out, since gputils aren't installed in the
5980 SF compile farm, so library won't compile
5982 * device/lib/Makefile.in (version 1.56): initially I've added in
5983 target 'all' the prerequestive 'model-pic16' so it compiled the
5984 pic16 library, but now I've commented it out for the same reasons
5986 * added targets 'model-pic16' and 'objects-pic16' to compile the
5988 * added target 'port-specific-objects-pic16' to handle the
5989 generated libraries and copy them into the build/ directory
5990 * added target 'clean-intermediate-pic16' to clean intermediate
5991 files into pic16 directory
5992 * in target 'installdirs' added line to create directory pic16 in

6239 LEFT_OP (left shift)
6241 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6243 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6244 (default behaviour).
6246 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6248 A python script to validate compiler diagnostic messages. It can be
6249 used to verify that sdcc complains about bad c source code and
6250 gives a good location of the error.
6251 * support/valdiag/Makefile,
6252 * support/valdiag/valdiag.py,
6253 * support/valdiag/tests/*
6255 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6270 Bug reported from Jesus Calvino-Fraga
6272 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6274 * sdcc.spec: updated
6275 * device/include/Makefile.in: don't install CVS directories
6276 * device/lib/Makefile.in: added removal of CVS directories after install
6277 * doc/Makefile: fixed install, added local_icons
6278 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6279 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6280 * src/ds390/gen.c (genRightShift): fixed bug #870788
6281 * src/SDCCast.c (decorateType): fixed bug #870781
6283 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6285 PIC16 port related changes:
6286 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6287 added variable stackPos,
6289 * gen.c: genCall, assignResultValue: added support for
6290 pushing/retrieving function parameters to/from stack,
6291 genFunction,genEndFunction: setup stack frame for the
6293 genAddrOf: will be changed according to bug 863624
6295 * added files genutils.c and genutils.h which contain gen*
6296 debugged and optimised functions extracted from gen.c
6298 * glue.c: added variable 'externs' which holds extern symbols,
6299 pic16emitRegularMap: is modified to properly handle relocatable
6300 symbols under the new scheme,
6301 pic16createInterruptVect: is modified
6302 pic16printPublics: is modified to emit 'global' assembler directives,
6303 added pic16_printExterns to print extern symbols,
6304 pic16glue: initializes stack/frame pointer in the beginning of
6305 the assembly output. Temporary hack, will be corrected later,
6306 because gplink yet does not support stack and SDCC does not
6307 yet support a type of crt0.o object to create the final binary.
6309 * Removed many lines that contain 8051 legacy code.
6310 * The code is finally placed under a 'code' directive.
6311 * Added port specific options.
6313 * _process_pragma: simplified since now we do not need *special*
6314 include file to define SFR registers. But a separate header
6315 will be needed. This will be developed later.
6316 * _pic16_parseOptions: added, parses port specific options:
6317 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6318 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6319 --preplace-udata-with=
6321 * _pic16_setDefaultOptions: modified to initialize section names,
6322 but hack is temporarly out of order since it needs improvement.
6323 * _pic16_genAssemblerPreamble: configuration words are emitted by
6324 their address instead of their name. This part is incomplete and
6325 supports only the 18Fxx2 devices. Other devices will emit an error
6326 during assembly since they do not contain the same set of config
6328 * _pic16_genIVT: is modified,
6330 * pcode.c: added definitions for some hardware registers that are needed
6332 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6333 All PCI entries are updated. Now LFSR is supported.
6334 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6335 * added pic16_newpCodeOpLit2 to support instructions with
6336 two literal arguments
6337 * pic16_pCode2str: corrected code that emits assembler instructions
6338 with two literal operands and those that have an access bit modifier
6339 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6340 this fixes a bug which caused some labels to be lost, when an
6341 assembler directive was added, i.e. banksel,
6342 * pic16_FixRegisterBanking: improved logic that causes the insertion
6344 * InlineFunction: functions that are called once, are not any more
6345 inlined. This can be a port option in the future,
6347 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6349 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6350 hold the corresponding uninitialized symbols,
6351 * pic16_allocProcessorRegister: registers have explicit marked the
6353 * pic16_allocInternalRegister: registers are explicit marked as
6355 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6356 processing list, so bit registers were lost,
6359 * ralloc.h: added field 'accessBank' and original symbol operand
6360 in register definition,
6361 * removed the field isMapped from register definition,
6363 ** Several functions have been removed from various sources:
6364 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6365 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6366 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6367 pic16_assignRelocatableRegisters
6369 ** others have been introduced:
6370 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6371 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6373 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6375 * support/scripts/inc2h.pl: changed definition of BIT_AT
6376 to emit 'sbit at' instead of 'bit at'. This was a request.
6378 PIC16 port related preliminary changes:
6379 * gen.c: prefixed function popRegFromString with
6380 pic16_ and all references to it corrected
6381 * pcode.c: all pic16_pc_* hardware registers prefixed
6382 with underscore (_),
6383 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6384 * ralloc.c: newReg(): when register is REG_SFR then
6385 set address to rIdx,
6386 pic16_allocProcessorRegister(): marks register wasUsed=0
6387 pic16_writeUsedRegs(): added a call to assign processor
6388 registers via pic16_assignFixedRegisters
6390 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6392 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6393 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6394 variables in unused register banks. Also the SSEG is placed
6395 wherever there is enough space for it, and IDATA can be anywhere
6396 in internal RAM. For now compile using -Wl-Y[stack_size].
6397 The mem file is different for this option as well, since it
6398 makes no sense of talking about DSEG lenght.
6400 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6402 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6403 in certain cases, e.g. when ROM assignment, patch provided
6404 from Albert den Haan.
6406 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7408 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7409 fetching of the pointer
7410 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7411 copied from genNearPointerSet()
7412 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7413 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7414 If they pop r0/r1 they must be called in the opposite order than aopOp().
7415 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7416 (resp. --stack-auto), prepared for --xstack

7427 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7429 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7430 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7431 type for bits was changed. It resulted in bit variables becoming
7432 global, which is not permitted in PIC 14 assembly output.
7434 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7436 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7449 A few small changes that speed up the peephole optimizer.
7453 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7455 Try to make the peephole optimizer smarter by maintaining
7456 an association between the assembly source code and the
7457 iCodes that originated them. Put this information to use
7458 with a new peephole rule condition "notVolatile" so that
7459 the rules can be aggressive yet still safe.
7464 * src/mcs51/peeph.def
7466 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7470 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7471 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7472 if the left or right operand symbols have the accuse flag set.
7474 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7476 Changed the type of the result of the ! (NOT) operator to char;
7477 previously it returned the same type as the source. This allows
7478 us to eliminate all the genFloatNot functions (all of its target
7479 implementations were very buggy) since !float can use the same
7482 * src/SDCCicode.c (ast2iCode): ! returns char
7483 * src/mcs51/gen.c (genNot, genNotFloat),
7484 * src/ds390/gen.c (genNot, genNotFloat),
7485 * src/z80/gen.c (genNot, genNotFloat),
7486 * src/pic/gen.c (genNot, genNotFloat),

7489 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7491 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7492 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7493 during interrupts. Ensure WSAVE is located at a shared bank address.
7494 2. Fixed page selection in some places
7495 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7496 the registers name strings.
7497 4. Fixed "signed / unsigned compare" compiler warnings.
7498 5. The PIC port manages its own allocation of the general purpose
7499 registers, but makes no attempt to reuse them. As a result when
7500 compiling it soon runs out of general purpose registers. Some
7501 additional code was added to the files pcode.c and device.c to walk
7502 through the function call tree and rename the registers so that they
7512 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7513 genPlus() & genMinus() when the result is the same as left or right
7515 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7519 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7521 Made bitfield a distinct type from bit so that bitfields
7522 convert as per ANSI C and bits retain their traditional
7523 boolean style behaviour. Implemented bitfield support in
7531 * src/ds390/gen.c: bit v bitfield split
7532 * src/z80/gen.c: New support for bitfields
7533 * support/regression/tests/bitfields.c: reenabled z80,
7536 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7538 Rules 246.x, 247.x relate to bitfields, the others speed up
7539 access to xdata mapped I/O devices.
7541 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7543 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7545 Cleaned up genPackBits and genUnpackBits and added two helper
7546 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7547 for literal assignments in genPackBits (thanks to Frieder for
7553 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7555 Fixed bug #748310 (pointer to function type mishandled when the
7556 function name is omitted). Also fixed a SIGSEGV when a function
7557 attribute (reentrant, etc) is used on a non-function or on a
7558 function but misplaced before the parameter list.
7560 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7562 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7563 * support/Util/SDCCerr.h,
7564 * support/Util/SDCCerr.c: Added func attr misuse error msg

7585 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7587 Made the constant following the "interrupt" keyword optional. If
7588 omitted, the function will not automatically be given an entry
7589 in the interrupt vector table (similar to #pragma NOIV, but
7590 less syntacticly kludgy). The interrupt number is also now
7591 range checked. Also fixed a bug in the high order bit example

7607 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7609 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7610 be re-activated by defining REDUCE_LITERALS)
7611 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7612 unsigned, but are signed by default
7613 * src/SDCCval.c (constVal): rearranged
7614 * src/SDCCval.c (valMod): preliminary fix
7615 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8121 added if/endif conditional macros to remove options help
8122 messages from optionsTable when a port is not configured, added
8123 support for the PIc16 port in the ports table, when executing
8124 the compiler with no port specified on command line, a default
8125 port is selected with the new macro DEFAULT_PORT which is
8126 defined in port.h, in setDefaultOptions() linkOptions is removed
8127 from initialization assignment, since now it is a set,
8128 parseCmdLine uses setParseWithComma for linkOptions, in
8129 linkEdit() linkOptions are accessed with new function indexSet()
8130 which returns the i'th item of a set variable. See SDCCset.c, in
8131 linkEdit() when calling buildCmdLine(), added linkOptions as
8132 last argument. Now users can pass arguments to gplink via the
8133 -Wl option, main() uses pic16glue() to glue up pic16 programs

8147 gpasm complaining and test the linkage with gplink, _linkCmd and
8148 _asmCmd changed to be more gplink and gpasm friendly
8149 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8150 produced an error when parsed, peep rule 12 is added to utilize
8151 movff, but it is commented out since the pCode does not support
8152 yet a command with 2 address arguments
8154 2003-05-18 <johan AT balder>
8156 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8183 2003-05-11 Borut Razem <borut.razem AT siol.net>
8185 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9193 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9194 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9195 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9197 2003-01-04 <johan AT balder>
9199 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9201 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9202 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9204 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9214 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9215 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9217 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9219 * in \sdcc\as\mcs51\ changed these files in order to create an
9220 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9221 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9222 following files to include the previous two files: aslink.dsp,
9223 Makefile.aslink, Makefile.bcc, and Makefile.in.
9225 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9226 .adb instead of .cdb
9228 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9230 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9231 value from option --iram-size.
9233 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9235 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9238 2002-09-18 <wiml AT hhhh.org>
9240 * SDCClrange.h: exposed setFromRange() and setToRange()
9241 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9242 packRegsForAccUse() (bug 542397)
9243 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9244 multiple times and emitting the fetch operations more than once
9245 added aopGetUsesAcc() function to allow binary operators to
9246 fetch their operands in the correct order; made genMinus() emit
9247 compact code for X = LITERAL - Y
9249 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9250 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9251 sprintf() in line 1267.
9253 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9254 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9257 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9258 Changes to aslink (All the changes are marked with 'JCF'):
9260 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9263 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9264 area BSEG. Also moves, if possible, the DATA area down into the internal
9265 ram so more space is available.
9267 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9270 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9271 not bytes. Function summary() which creates a memory usage summary
9272 file with extension .mem. Reports of overlaping stack and small stack
9273 size. If the space for the stack is less than 16 bytes aslink trows a
9276 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9277 the 8051. Option 'y' for memory summary output file.
9279 Changes to sdcc (All the changes are marked with 'JCF'):
9281 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9283 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9284 overlaying area for it (uses RegBankUsed[4]).
9286 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9287 bank zero as used by default. By default aslink locates the stack
9288 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9289 the creation of the .mem file. Delegates the allocation of data area
9290 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9291 the begining of the stack area to aslink.
9293 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9294 glue() in SDCCglue.c creates an area for it.
9296 2002-09-03 Borut Razem <borut.razem AT siol.net>
9297 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9298 sdcc/src/pic/glue.c:
9299 introduced atexit() handler for teporay files removal in case of
9300 errors, assertions, ...
9302 2002-08-29 Borut Razem <borut.razem AT siol.net>
9303 * sdcc/support/cpp2/auto-host_vc_in.h:
9304 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9305 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9306 Maybe there is a similar problem with BORLANDC? It should be checked!
9308 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9309 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9310 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9311 was not executed, and the compiler (cl) launched a warning:
9312 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9314 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9315 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9317 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9318 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9320 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9321 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9322 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9323 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9324 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9325 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9326 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9327 - added Release configuration in VS projects
9328 - review of compiler an linker options
9329 - VC .exe files are generated in bin_vc directory, not to interfere
9330 with binaries generated from other projects (cygwin, mingw, bcc ...)
9332 * sdcc/src/yacc.dsp: added
9334 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9335 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9336 and insert the version number definitions from .version
9338 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9340 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9341 added - genarate auto-host.h using auto-host_vc_in.h as template
9344 removed from CVS, generated automatically
9346 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9347 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9349 2002-08-11 Borut Razem <borut.razem AT siol.net>
9350 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9352 2002-08-10 Borut Razem <borut.razem AT siol.net>
9353 * src/SDCCmain.c (main):
9354 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9355 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9356 The consequence was that some temporary files were not removed.
9359 unification of code in functions tempfilename() and tempfile():
9360 function tempnam() is defined in Visual Studio 6.0 and .NET
9362 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9364 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9365 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9366 - removed compiler command line option /WX: Treats all warnings as errors
9367 - update a list of source files, included into the project
9369 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9370 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9371 changed project type to Generic Project so that can be correcly converted to VS.NET project
9373 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9375 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9377 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9379 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9380 added return 0 statements after assert() to make compiler happy
9382 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9383 added newline in the def file to keep MSC compiler satisfied
9385 * sdcc/src/z80/gen.c:
9386 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9387 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9388 - solved MSC error in function aopDump()
9390 * sdcc_vc.h: define PREFIX as "\\sdcc"
9392 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9393 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9395 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9396 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9397 - Rewrote the register banking algorithm.
9398 - Added pCode live-range analysis to registers (for now, only non-used and
9399 singly-used registers optimized away)
9401 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9403 * 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.
9405 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9432 2002-03-28 Johan Knol <johan AT balder>
9434 * src/SDCCval.c: fixed bug #532436
9436 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9438 Added "char *Processor" field to the port structure.
9441 Added -p option. Allows port dependent processor to be specified.
9444 Initialized the new field char *Processor field to NULL in all ports
9447 Compiler generated registers for interrupt context saving
9448 were not getting allocated.
9450 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9453 Fixed left shift. Will promote the left side of a left shift
9454 if a) left shifting more than size of operand or b) when assigned
9455 to something size > size of left side
9457 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9459 tons of changes. Register allocation has been
9460 rewritten. Added customization for the various PICs. Flow
9461 analysis is restructured. ...
9467 Added. device.c is a PIC port hack to accomodate variations

9568 Previous fix was not good. basic blocks that have "break" or "return" are
9569 not really partof a loop , but live ranges used in these blocks should
9570 be live thru the entire loop, so set partOfLoop but don't add them to
