2070 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2072 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2074 * device/lib/printf_large.c: removed inline assembly for portability and
2075 readability. Use printf_fast if speed or size are more important.
2076 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2077 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2079 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2081 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2082 prevent compiler warning
2084 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2086 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2087 moved to level 0 and declared as static. Also they are explicit
2088 placed in access bank. This was necessery because some times they
2089 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2090 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2091 optimizations. Currently only compare to unsigned char is implemented,
2092 * src/pic16/gen.c: added fReturnIdx array,
2093 * (struct resolvedIfx) is moved to gen.h and made public,
2094 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2095 * (aopForSym): added an optimization to directly store in stack of
2096 the operand of a SEND iCode,
2097 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2098 but as registers instead (AOP_REG) using the fReturnIdx array,
2099 * (pic16_freeAsmop): remove the freed register from the
2100 _G.sregsAlloc field,
2101 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2102 a compare of 'WREG',
2103 * (pic16_popGetTempRegCond): changed function prototype, now
2104 function takes also a bitVector argument v which holds the current
2105 set of registers that are allocated for stack access by aopForSym,
2106 registers allocated in aopForSym for accessing stack symbols are not
2107 any more part of the functions usedRegs field,
2108 * (genCall): some times aopOp is called for a stack variable to be
2109 send, aopForSym might perform the push, if this is true make sure
2110 that genCall doesn't push the variable twice by testing _G.resDirect,
2111 * (genFunction): changed testing for unspecified interrupt number
2112 from 256 to INTNO_UNSPEC,
2113 * modified selection scheme of frame pointer generation. Previously
2114 if function did use local registers a frame pointer was generated,
2115 now a frame pointer is generated only if function has arguments
2116 (that need PLUSW2 register access), or has stack arguments, or the
2117 compiler is not instructed to omit the frame pointer,
2118 * (genEndFunction): before restoring local registers that were saved
2119 in the function preamble, also restore the registers that *might*
2120 have been allocated for stack access,
2121 * (genRet): removed some old comments,
2122 * (genCmp, the active (RN's) version): added a call to the
2123 pic16_genCmp_special function to perform the compare with a more
2124 robust and optimized way,
2125 * (genInline): a feature has been added in inline code generation,
2126 which allows a wildcard variable substitution when writing inline
2127 assembly. Code is incomplete and experimental therefore undocumented,
2128 * (genCast): changed order of aopOp for result and right to allow
2129 aopForSym to directly load the result if possible,
2130 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2131 perform an optimized compare on some selected special occasions,
2132 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2133 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2134 generate an IVT any more,
2135 * src/pic16/main.c (pic16_optionsTable): added command line option
2137 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2138 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2140 * src/pic16/NOTES: Raphael Neider added in list of active developers
2141 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2142 jumptable_end to prevent bug #,
2143 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2144 inCond and outCond fields,
2145 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2146 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2147 turn off register spilling,
2148 * (packRegsForOneUse): synced with other ports' versions although it
2149 is not used currently,
2150 * (pic16_packRegisters): added an optimization while reading
2151 structure bitfields, some registers may be saved (malloc code is
2152 decreased by 80 bytes)

2799 generated for switch statements. For now you need to set the
2800 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2801 Now 4 algorithms for mcs51 jumptable generation are used:
2802 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2836 * added libc directory. The current version of LibC contains string
2837 functions, ctype functions and macros and some functions of the
2838 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2839 be extensively tested in the future. Standard disclaimer here.
2840 Library is not automatically build yet. But one can build it by
2841 invoking 'make' inside the libc directory.

2852 * (pic16_storeForReturn): optimized return of 0,
2853 * (genCmp): experimental code for new genCmp which uses PIC18's
2854 special compare&skip instructions. Initial tests fail some times
2855 with variables grater than 1 byte in size, so new code is disabled,
2856 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2858 * (genCast): began a fix to optimize the casting of a bit to another
2859 bit, now assigning a bitfield to another bitfield will fail, sorry,

2868 and 1 for banking instruction,
2869 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2870 caused stop processing pCodes after a inline assembly block,
2871 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2873 registers when it shouldn't,
2874 * src/pic16/ralloc.c (allocReg): add preliminary support for
2875 supporting a limited set of temporary registers,
2877 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5885 loaded with the linker search paths (-L arguments) and the libraries
5886 to be linked with the current source (-l arguments). Changes
5887 currently will affect only the pic16 port.
5888 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5889 include path the port specific paths and port specific libraries,
5890 * gplink command now contains the $3 argument,
5891 * src/pic16/device.h,

5908 Documenting changes from previous commits.
5909 * configure.in (version 1.56),
5910 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5911 when generating output files to configure the pic16 library,
5912 but now I've commented it out, since gputils aren't installed in the
5913 SF compile farm, so library won't compile
5915 * device/lib/Makefile.in (version 1.56): initially I've added in
5916 target 'all' the prerequestive 'model-pic16' so it compiled the
5917 pic16 library, but now I've commented it out for the same reasons
5919 * added targets 'model-pic16' and 'objects-pic16' to compile the
5921 * added target 'port-specific-objects-pic16' to handle the
5922 generated libraries and copy them into the build/ directory
5923 * added target 'clean-intermediate-pic16' to clean intermediate
5924 files into pic16 directory
5925 * in target 'installdirs' added line to create directory pic16 in

5929 added lines to copy all header files to installation path,
5930 * in target 'installdirs' added line create directory for pic16
5931 headers in the installation path

6165 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6167 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
6169 * support/valdiag/tests/overflow.c: added
6170 * src/SDCCast.c (decorateType),
6171 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6172 LEFT_OP (left shift)
6174 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6176 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6177 (default behaviour).
6179 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6181 A python script to validate compiler diagnostic messages. It can be
6182 used to verify that sdcc complains about bad c source code and
6183 gives a good location of the error.
6184 * support/valdiag/Makefile,
6185 * support/valdiag/valdiag.py,
6186 * support/valdiag/tests/*
6188 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6190 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6191 * src/SDCCsymt.c (newEnumType),
6193 * support/Util/SDCCerr.c,
6194 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6196 * support/regression/tests/enum.c: added test for enum values that
6197 require at least 2 bytes of storage.
6199 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6201 * src/common.h: added ifndef/define/endif macros
6202 around the header file.
6203 Bug reported from Jesus Calvino-Fraga
6205 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6207 * sdcc.spec: updated
6208 * device/include/Makefile.in: don't install CVS directories
6209 * device/lib/Makefile.in: added removal of CVS directories after install
6210 * doc/Makefile: fixed install, added local_icons
6211 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6212 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6213 * src/ds390/gen.c (genRightShift): fixed bug #870788
6214 * src/SDCCast.c (decorateType): fixed bug #870781
6216 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6218 PIC16 port related changes:
6219 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6220 added variable stackPos,
6222 * gen.c: genCall, assignResultValue: added support for
6223 pushing/retrieving function parameters to/from stack,
6224 genFunction,genEndFunction: setup stack frame for the
6226 genAddrOf: will be changed according to bug 863624
6228 * added files genutils.c and genutils.h which contain gen*
6229 debugged and optimised functions extracted from gen.c
6231 * glue.c: added variable 'externs' which holds extern symbols,
6232 pic16emitRegularMap: is modified to properly handle relocatable
6233 symbols under the new scheme,
6234 pic16createInterruptVect: is modified
6235 pic16printPublics: is modified to emit 'global' assembler directives,
6236 added pic16_printExterns to print extern symbols,
6237 pic16glue: initializes stack/frame pointer in the beginning of
6238 the assembly output. Temporary hack, will be corrected later,
6239 because gplink yet does not support stack and SDCC does not
6240 yet support a type of crt0.o object to create the final binary.
6242 * Removed many lines that contain 8051 legacy code.
6243 * The code is finally placed under a 'code' directive.
6244 * Added port specific options.
6246 * _process_pragma: simplified since now we do not need *special*
6247 include file to define SFR registers. But a separate header
6248 will be needed. This will be developed later.
6249 * _pic16_parseOptions: added, parses port specific options:
6250 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6251 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6252 --preplace-udata-with=
6254 * _pic16_setDefaultOptions: modified to initialize section names,
6255 but hack is temporarly out of order since it needs improvement.
6256 * _pic16_genAssemblerPreamble: configuration words are emitted by
6257 their address instead of their name. This part is incomplete and
6258 supports only the 18Fxx2 devices. Other devices will emit an error
6259 during assembly since they do not contain the same set of config
6261 * _pic16_genIVT: is modified,
6263 * pcode.c: added definitions for some hardware registers that are needed
6265 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6266 All PCI entries are updated. Now LFSR is supported.
6267 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6268 * added pic16_newpCodeOpLit2 to support instructions with
6269 two literal arguments
6270 * pic16_pCode2str: corrected code that emits assembler instructions
6271 with two literal operands and those that have an access bit modifier
6272 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6273 this fixes a bug which caused some labels to be lost, when an
6274 assembler directive was added, i.e. banksel,
6275 * pic16_FixRegisterBanking: improved logic that causes the insertion
6277 * InlineFunction: functions that are called once, are not any more
6278 inlined. This can be a port option in the future,
6280 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6282 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6283 hold the corresponding uninitialized symbols,
6284 * pic16_allocProcessorRegister: registers have explicit marked the
6286 * pic16_allocInternalRegister: registers are explicit marked as
6288 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6289 processing list, so bit registers were lost,
6292 * ralloc.h: added field 'accessBank' and original symbol operand
6293 in register definition,
6294 * removed the field isMapped from register definition,
6296 ** Several functions have been removed from various sources:
6297 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6298 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6299 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6300 pic16_assignRelocatableRegisters
6302 ** others have been introduced:
6303 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6304 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6306 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6308 * support/scripts/inc2h.pl: changed definition of BIT_AT
6309 to emit 'sbit at' instead of 'bit at'. This was a request.
6311 PIC16 port related preliminary changes:
6312 * gen.c: prefixed function popRegFromString with
6313 pic16_ and all references to it corrected
6314 * pcode.c: all pic16_pc_* hardware registers prefixed
6315 with underscore (_),
6316 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6317 * ralloc.c: newReg(): when register is REG_SFR then
6318 set address to rIdx,
6319 pic16_allocProcessorRegister(): marks register wasUsed=0
6320 pic16_writeUsedRegs(): added a call to assign processor
6321 registers via pic16_assignFixedRegisters
6323 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6325 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6326 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6327 variables in unused register banks. Also the SSEG is placed
6328 wherever there is enough space for it, and IDATA can be anywhere
6329 in internal RAM. For now compile using -Wl-Y[stack_size].
6330 The mem file is different for this option as well, since it
6331 makes no sense of talking about DSEG lenght.
6333 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6335 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6336 in certain cases, e.g. when ROM assignment, patch provided
6337 from Albert den Haan.
6339 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6482 * src/mcs51/peephole.def,
6483 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6495 multiply defined with mismatching "at" address.
6497 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6499 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
6500 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

6578 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6580 * src/SDCCast.c (decorateType): disabled a transformation I added in
6581 revision 1.188 (access to fields of a structure at an absolute address);
6582 it breaks with bitfields, extern declarations, and gcse analysis.
6583 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6584 could be assigned through a pointer, so don't complain.
6585 * src/SDCCast.c (astErrors),
6587 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7222 * src/SDCCsymt.c (sclsFromPtr),
7224 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7225 support for standard C idiom of memory mapped variables; for
7226 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7227 to xdata int at 0x1234 tempvar = 1.
7228 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7229 provided by Akiya ISHIDA

7245 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7247 Fixed bug #621531 (const & volatile confusion in the type chain).
7248 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7249 refer to the const or volatile state of the pointer itself.

7314 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7315 pcoderegs.h, ralloc.c, ralloc.h
7316 * main.c: added top header and GPL license notice

7340 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7341 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7342 fetching of the pointer
7343 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7344 copied from genNearPointerSet()
7345 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7346 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7347 If they pop r0/r1 they must be called in the opposite order than aopOp().
7348 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7349 (resp. --stack-auto), prepared for --xstack

7360 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7362 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7363 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7364 type for bits was changed. It resulted in bit variables becoming
7365 global, which is not permitted in PIC 14 assembly output.
7367 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7369 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7371 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7373 Z80 and MCS51 linkers complaint if a public symbol is defined

7382 A few small changes that speed up the peephole optimizer.
7386 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7388 Try to make the peephole optimizer smarter by maintaining
7389 an association between the assembly source code and the
7390 iCodes that originated them. Put this information to use
7391 with a new peephole rule condition "notVolatile" so that
7392 the rules can be aggressive yet still safe.
7397 * src/mcs51/peeph.def
7399 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7403 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7404 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7405 if the left or right operand symbols have the accuse flag set.
7407 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7409 Changed the type of the result of the ! (NOT) operator to char;
7410 previously it returned the same type as the source. This allows
7411 us to eliminate all the genFloatNot functions (all of its target
7412 implementations were very buggy) since !float can use the same
7415 * src/SDCCicode.c (ast2iCode): ! returns char

7417 * src/ds390/gen.c (genNot, genNotFloat),
7418 * src/z80/gen.c (genNot, genNotFloat),
7419 * src/pic/gen.c (genNot, genNotFloat),

7424 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7425 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7426 during interrupts. Ensure WSAVE is located at a shared bank address.
7427 2. Fixed page selection in some places
7428 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7429 the registers name strings.
7430 4. Fixed "signed / unsigned compare" compiler warnings.
7431 5. The PIC port manages its own allocation of the general purpose
7432 registers, but makes no attempt to reuse them. As a result when
7433 compiling it soon runs out of general purpose registers. Some
7434 additional code was added to the files pcode.c and device.c to walk
7435 through the function call tree and rename the registers so that they
7445 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7446 genPlus() & genMinus() when the result is the same as left or right
7448 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7452 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7454 Made bitfield a distinct type from bit so that bitfields
7455 convert as per ANSI C and bits retain their traditional
7456 boolean style behaviour. Implemented bitfield support in
7464 * src/ds390/gen.c: bit v bitfield split
7465 * src/z80/gen.c: New support for bitfields
7466 * support/regression/tests/bitfields.c: reenabled z80,
7469 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7471 Rules 246.x, 247.x relate to bitfields, the others speed up
7472 access to xdata mapped I/O devices.
7474 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7476 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7478 Cleaned up genPackBits and genUnpackBits and added two helper
7479 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7480 for literal assignments in genPackBits (thanks to Frieder for
7486 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7488 Fixed bug #748310 (pointer to function type mishandled when the
7489 function name is omitted). Also fixed a SIGSEGV when a function
7490 attribute (reentrant, etc) is used on a non-function or on a
7491 function but misplaced before the parameter list.
7493 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7495 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7496 * support/Util/SDCCerr.h,
7497 * support/Util/SDCCerr.c: Added func attr misuse error msg

7518 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7520 Made the constant following the "interrupt" keyword optional. If
7521 omitted, the function will not automatically be given an entry
7522 in the interrupt vector table (similar to #pragma NOIV, but
7523 less syntacticly kludgy). The interrupt number is also now
7524 range checked. Also fixed a bug in the high order bit example

7538 * src/SDCCicode.c (operandOperation): rewritten some ops
7539 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7540 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7542 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7543 be re-activated by defining REDUCE_LITERALS)
7544 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7545 unsigned, but are signed by default
7546 * src/SDCCval.c (constVal): rearranged
7547 * src/SDCCval.c (valMod): preliminary fix
7548 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7590 constants are unsigned; added recognition of "u" flag for unsigned
7591 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7592 * src/SDCCval.c (valDiv, valMod): fixed signdness
7593 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7594 signedness of modulo, left and right shift

8054 added if/endif conditional macros to remove options help
8055 messages from optionsTable when a port is not configured, added
8056 support for the PIc16 port in the ports table, when executing
8057 the compiler with no port specified on command line, a default
8058 port is selected with the new macro DEFAULT_PORT which is
8059 defined in port.h, in setDefaultOptions() linkOptions is removed
8060 from initialization assignment, since now it is a set,
8061 parseCmdLine uses setParseWithComma for linkOptions, in
8062 linkEdit() linkOptions are accessed with new function indexSet()
8063 which returns the i'th item of a set variable. See SDCCset.c, in
8064 linkEdit() when calling buildCmdLine(), added linkOptions as
8065 last argument. Now users can pass arguments to gplink via the
8066 -Wl option, main() uses pic16glue() to glue up pic16 programs

8080 gpasm complaining and test the linkage with gplink, _linkCmd and
8081 _asmCmd changed to be more gplink and gpasm friendly
8082 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8083 produced an error when parsed, peep rule 12 is added to utilize
8084 movff, but it is commented out since the pCode does not support
8085 yet a command with 2 address arguments
8087 2003-05-18 <johan AT balder>
8089 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8116 2003-05-11 Borut Razem <borut.razem AT siol.net>
8118 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8119 the path of bin directory, so that PATH is the only env. variable, which has to be set

9104 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9105 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9107 2003-01-07 <johan AT balder>
9109 * src/SDCCast.c (decorateType): fixed bug #600035
9111 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9112 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9122 2003-01-06 <johan AT balder>
9124 * src/SDCCicode.c: fixed array add
9126 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9127 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9128 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9130 2003-01-04 <johan AT balder>
9132 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9134 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9135 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9137 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9138 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9139 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9141 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9142 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9144 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9145 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9147 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9148 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9150 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9152 * in \sdcc\as\mcs51\ changed these files in order to create an
9153 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9154 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9155 following files to include the previous two files: aslink.dsp,
9156 Makefile.aslink, Makefile.bcc, and Makefile.in.
9158 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9159 .adb instead of .cdb
9161 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9163 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9164 value from option --iram-size.
9166 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9168 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9171 2002-09-18 <wiml AT hhhh.org>
9173 * SDCClrange.h: exposed setFromRange() and setToRange()
9174 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9175 packRegsForAccUse() (bug 542397)
9176 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9177 multiple times and emitting the fetch operations more than once
9178 added aopGetUsesAcc() function to allow binary operators to
9179 fetch their operands in the correct order; made genMinus() emit
9180 compact code for X = LITERAL - Y
9182 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9183 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9184 sprintf() in line 1267.
9186 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9187 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9190 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9191 Changes to aslink (All the changes are marked with 'JCF'):
9193 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9196 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9197 area BSEG. Also moves, if possible, the DATA area down into the internal
9198 ram so more space is available.
9200 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9203 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9204 not bytes. Function summary() which creates a memory usage summary
9205 file with extension .mem. Reports of overlaping stack and small stack
9206 size. If the space for the stack is less than 16 bytes aslink trows a
9209 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9210 the 8051. Option 'y' for memory summary output file.
9212 Changes to sdcc (All the changes are marked with 'JCF'):
9214 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9216 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9217 overlaying area for it (uses RegBankUsed[4]).
9219 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9220 bank zero as used by default. By default aslink locates the stack
9221 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9222 the creation of the .mem file. Delegates the allocation of data area
9223 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9224 the begining of the stack area to aslink.
9226 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9227 glue() in SDCCglue.c creates an area for it.
9229 2002-09-03 Borut Razem <borut.razem AT siol.net>
9230 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9231 sdcc/src/pic/glue.c:
9232 introduced atexit() handler for teporay files removal in case of
9233 errors, assertions, ...
9235 2002-08-29 Borut Razem <borut.razem AT siol.net>
9236 * sdcc/support/cpp2/auto-host_vc_in.h:
9237 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9238 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9239 Maybe there is a similar problem with BORLANDC? It should be checked!
9241 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9242 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9243 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9244 was not executed, and the compiler (cl) launched a warning:
9245 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9247 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9248 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9250 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9251 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9253 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9254 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9255 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9256 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9257 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9258 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9259 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9260 - added Release configuration in VS projects
9261 - review of compiler an linker options
9262 - VC .exe files are generated in bin_vc directory, not to interfere
9263 with binaries generated from other projects (cygwin, mingw, bcc ...)
9265 * sdcc/src/yacc.dsp: added
9267 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9268 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9269 and insert the version number definitions from .version
9271 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9273 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9274 added - genarate auto-host.h using auto-host_vc_in.h as template
9277 removed from CVS, generated automatically
9279 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9280 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9282 2002-08-11 Borut Razem <borut.razem AT siol.net>
9283 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9285 2002-08-10 Borut Razem <borut.razem AT siol.net>
9286 * src/SDCCmain.c (main):
9287 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9288 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9289 The consequence was that some temporary files were not removed.
9292 unification of code in functions tempfilename() and tempfile():
9293 function tempnam() is defined in Visual Studio 6.0 and .NET
9295 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9297 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9298 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9299 - removed compiler command line option /WX: Treats all warnings as errors
9300 - update a list of source files, included into the project
9302 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9303 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9304 changed project type to Generic Project so that can be correcly converted to VS.NET project
9306 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9308 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9310 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9312 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9313 added return 0 statements after assert() to make compiler happy
9315 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9316 added newline in the def file to keep MSC compiler satisfied
9318 * sdcc/src/z80/gen.c:
9319 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9320 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9321 - solved MSC error in function aopDump()
9323 * sdcc_vc.h: define PREFIX as "\\sdcc"
9325 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9326 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9328 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9329 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9330 - Rewrote the register banking algorithm.
9331 - Added pCode live-range analysis to registers (for now, only non-used and
9332 singly-used registers optimized away)
9334 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9336 * 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.

9363 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9365 2002-03-28 Johan Knol <johan AT balder>
9367 * src/SDCCval.c: fixed bug #532436
9369 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9371 Added "char *Processor" field to the port structure.
9374 Added -p option. Allows port dependent processor to be specified.
9377 Initialized the new field char *Processor field to NULL in all ports
9380 Compiler generated registers for interrupt context saving
9381 were not getting allocated.
9383 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9386 Fixed left shift. Will promote the left side of a left shift
9387 if a) left shifting more than size of operand or b) when assigned
9388 to something size > size of left side
9390 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9392 tons of changes. Register allocation has been
9393 rewritten. Added customization for the various PICs. Flow
9394 analysis is restructured. ...
9400 Added. device.c is a PIC port hack to accomodate variations
9403 2002-03-13 Michael Hope <michaelh AT vroom>
9405 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9407 2002-03-04 johanknol <johanknol AT manik>
9409 * /src/SDCCval.c: fixed
9411 const unsigned char arr[][2] = { { 0, 1 } };
9412 t18.c:1: error: Initializer element is not constant
9414 2002-03-04 bela <bela AT manik>
9416 * /device/include/mcs51reg.h:
9417 ds89c420 register definition update
9419 2002-03-03 <johan AT FRIJA>

9498 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9500 * sdcc/src/SDCCloop.c:
9501 Previous fix was not good. basic blocks that have "break" or "return" are
9502 not really partof a loop , but live ranges used in these blocks should
9503 be live thru the entire loop, so set partOfLoop but don't add them to
9506 2002-02-21 <johan AT FRIJA>
9508 * src/SDCCcse.c: fixed bug #514308
9510 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9513 Fixed BUG #519583. If a conditional block ended in a return/break
9514 statement inside a loop, it was not being considered part of the loop.
9516 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9518 2002-02-10 Karl Bongers <karl AT turbobit.com>
9521 Fixed up SDCDB debugger somewhat. Updated debugger/README
9522 with lots of comments and notes.
9524 * device/examples/test2.c:
9525 Fix bug, "red" variable not being initialized(compiler complained).
9527 * device/examples/Makefile, examples/test3.c:
9528 Add Makefile in device/examples folder, compiles test3.c
9529 for use as a multiple module SDCDB test case.
9531 * sim/ucsim/cmd.src/cmdset.cc:
9532 Took out debug printfs in ucsim "next" command.
9535 Karl and Johan start ucsim XA support. Most dissassembly working,
9536 about 75% emulation done(plenty of work remaining).
9538 * sim/ucsim/z80.src:
9539 Add Z80 support to ucsim, add test-ucz80 regression test,
9540 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9541 Notice z80 compiler fails on examples/test3.c/crc code.
9543 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9545 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

9553 from a memory mapped port
9554 2) added __builtin_memcmp
9555 3) added __builtin_swapw swap bytes of a short
9557 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9558 1) handle multiple send & receives from register bank1
9559 2) ralloc can now allocate DPTR1 to some liveRanges
9561 * src/SDCCsymt.c, src/SDCCsymt.h:
9562 changes to handle multiple sends & receives
9565 added some pointer arithmetic optimization
9568 added some pointer arithmetic optimizations but not stable yet so not
9569 called from anywhere (will get this working shortly)
9571 * src/SDCCopt.c: fixed for multiple sends & receives
9574 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9575 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9576 set preprocessor defines (depending on options)
9578 * src/SDCCicode.c, src/SDCCicode.h:
9579 changes made to handle multiple sends & receives
9582 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
