2051 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2053 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2055 * device/lib/printf_large.c: removed inline assembly for portability and
2056 readability. Use printf_fast if speed or size are more important.
2057 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2058 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2060 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2062 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2063 prevent compiler warning
2065 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2067 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2068 moved to level 0 and declared as static. Also they are explicit
2069 placed in access bank. This was necessery because some times they
2070 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2071 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2072 optimizations. Currently only compare to unsigned char is implemented,
2073 * src/pic16/gen.c: added fReturnIdx array,
2074 * (struct resolvedIfx) is moved to gen.h and made public,
2075 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2076 * (aopForSym): added an optimization to directly store in stack of
2077 the operand of a SEND iCode,
2078 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2079 but as registers instead (AOP_REG) using the fReturnIdx array,
2080 * (pic16_freeAsmop): remove the freed register from the
2081 _G.sregsAlloc field,
2082 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2083 a compare of 'WREG',
2084 * (pic16_popGetTempRegCond): changed function prototype, now
2085 function takes also a bitVector argument v which holds the current
2086 set of registers that are allocated for stack access by aopForSym,
2087 registers allocated in aopForSym for accessing stack symbols are not
2088 any more part of the functions usedRegs field,
2089 * (genCall): some times aopOp is called for a stack variable to be
2090 send, aopForSym might perform the push, if this is true make sure
2091 that genCall doesn't push the variable twice by testing _G.resDirect,
2092 * (genFunction): changed testing for unspecified interrupt number
2093 from 256 to INTNO_UNSPEC,
2094 * modified selection scheme of frame pointer generation. Previously
2095 if function did use local registers a frame pointer was generated,
2096 now a frame pointer is generated only if function has arguments
2097 (that need PLUSW2 register access), or has stack arguments, or the
2098 compiler is not instructed to omit the frame pointer,
2099 * (genEndFunction): before restoring local registers that were saved
2100 in the function preamble, also restore the registers that *might*
2101 have been allocated for stack access,
2102 * (genRet): removed some old comments,
2103 * (genCmp, the active (RN's) version): added a call to the
2104 pic16_genCmp_special function to perform the compare with a more
2105 robust and optimized way,
2106 * (genInline): a feature has been added in inline code generation,
2107 which allows a wildcard variable substitution when writing inline
2108 assembly. Code is incomplete and experimental therefore undocumented,
2109 * (genCast): changed order of aopOp for result and right to allow
2110 aopForSym to directly load the result if possible,
2111 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2112 perform an optimized compare on some selected special occasions,
2113 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2114 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2115 generate an IVT any more,
2116 * src/pic16/main.c (pic16_optionsTable): added command line option
2118 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2119 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2121 * src/pic16/NOTES: Raphael Neider added in list of active developers
2122 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2123 jumptable_end to prevent bug #,
2124 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2125 inCond and outCond fields,
2126 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2127 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2128 turn off register spilling,
2129 * (packRegsForOneUse): synced with other ports' versions although it
2130 is not used currently,
2131 * (pic16_packRegisters): added an optimization while reading
2132 structure bitfields, some registers may be saved (malloc code is
2133 decreased by 80 bytes)
2135 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2137 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2138 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2139 this can be optimized more?
2141 2005-03-10 Raphael Neider <rneider AT web.de>
2143 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2144 genNearPointerGet): (hopefully) fixed access to bitfields via
2145 pointers (p->bitN = x; and x = p->bitN; failed)
2147 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2149 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
2151 2005-03-09 Raphael Neider <rneider AT web.de>

2779 Adding support for replacing ljmps with sjmps in jumptables
2780 generated for switch statements. For now you need to set the
2781 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2782 Now 4 algorithms for mcs51 jumptable generation are used:
2783 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2784 addresses loaded pc-relative for up to 112 cases and stack-pushing
2785 target addresses loaded with offset from dptr for up to 256 cases.

2815 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2817 * added libc directory. The current version of LibC contains string
2818 functions, ctype functions and macros and some functions of the
2819 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2820 be extensively tested in the future. Standard disclaimer here.
2821 Library is not automatically build yet. But one can build it by
2822 invoking 'make' inside the libc directory.

2833 * (pic16_storeForReturn): optimized return of 0,
2834 * (genCmp): experimental code for new genCmp which uses PIC18's
2835 special compare&skip instructions. Initial tests fail some times
2836 with variables grater than 1 byte in size, so new code is disabled,
2837 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2839 * (genCast): began a fix to optimize the casting of a bit to another
2840 bit, now assigning a bitfield to another bitfield will fail, sorry,

2849 and 1 for banking instruction,
2850 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2851 caused stop processing pCodes after a inline assembly block,
2852 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2854 registers when it shouldn't,
2855 * src/pic16/ralloc.c (allocReg): add preliminary support for
2856 supporting a limited set of temporary registers,
2858 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2864 (genFunction): optimize RECEIVE iCodes in reentrant functions
2866 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5866 loaded with the linker search paths (-L arguments) and the libraries
5867 to be linked with the current source (-l arguments). Changes
5868 currently will affect only the pic16 port.
5869 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5870 include path the port specific paths and port specific libraries,
5871 * gplink command now contains the $3 argument,
5872 * src/pic16/device.h,
5873 * src/pic16/device.c,: structure PIC_device is made public and
5874 renamed to PIC16_device, the same for variable Pics which is renamed

5889 Documenting changes from previous commits.
5890 * configure.in (version 1.56),
5891 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5892 when generating output files to configure the pic16 library,
5893 but now I've commented it out, since gputils aren't installed in the
5894 SF compile farm, so library won't compile
5896 * device/lib/Makefile.in (version 1.56): initially I've added in
5897 target 'all' the prerequestive 'model-pic16' so it compiled the
5898 pic16 library, but now I've commented it out for the same reasons
5900 * added targets 'model-pic16' and 'objects-pic16' to compile the
5902 * added target 'port-specific-objects-pic16' to handle the
5903 generated libraries and copy them into the build/ directory
5904 * added target 'clean-intermediate-pic16' to clean intermediate
5905 files into pic16 directory
5906 * in target 'installdirs' added line to create directory pic16 in

6160 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6162 A python script to validate compiler diagnostic messages. It can be
6163 used to verify that sdcc complains about bad c source code and
6164 gives a good location of the error.
6165 * support/valdiag/Makefile,
6166 * support/valdiag/valdiag.py,
6167 * support/valdiag/tests/*
6169 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6171 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6172 * src/SDCCsymt.c (newEnumType),
6174 * support/Util/SDCCerr.c,
6175 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6177 * support/regression/tests/enum.c: added test for enum values that
6178 require at least 2 bytes of storage.
6180 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6182 * src/common.h: added ifndef/define/endif macros
6183 around the header file.
6184 Bug reported from Jesus Calvino-Fraga
6186 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6188 * sdcc.spec: updated
6189 * device/include/Makefile.in: don't install CVS directories
6190 * device/lib/Makefile.in: added removal of CVS directories after install
6191 * doc/Makefile: fixed install, added local_icons
6192 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6193 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6194 * src/ds390/gen.c (genRightShift): fixed bug #870788
6195 * src/SDCCast.c (decorateType): fixed bug #870781
6197 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6199 PIC16 port related changes:
6200 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6201 added variable stackPos,
6203 * gen.c: genCall, assignResultValue: added support for
6204 pushing/retrieving function parameters to/from stack,
6205 genFunction,genEndFunction: setup stack frame for the
6207 genAddrOf: will be changed according to bug 863624
6209 * added files genutils.c and genutils.h which contain gen*
6210 debugged and optimised functions extracted from gen.c
6212 * glue.c: added variable 'externs' which holds extern symbols,
6213 pic16emitRegularMap: is modified to properly handle relocatable
6214 symbols under the new scheme,
6215 pic16createInterruptVect: is modified
6216 pic16printPublics: is modified to emit 'global' assembler directives,
6217 added pic16_printExterns to print extern symbols,
6218 pic16glue: initializes stack/frame pointer in the beginning of
6219 the assembly output. Temporary hack, will be corrected later,
6220 because gplink yet does not support stack and SDCC does not
6221 yet support a type of crt0.o object to create the final binary.
6223 * Removed many lines that contain 8051 legacy code.
6224 * The code is finally placed under a 'code' directive.
6225 * Added port specific options.
6227 * _process_pragma: simplified since now we do not need *special*
6228 include file to define SFR registers. But a separate header
6229 will be needed. This will be developed later.
6230 * _pic16_parseOptions: added, parses port specific options:
6231 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6232 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6233 --preplace-udata-with=
6235 * _pic16_setDefaultOptions: modified to initialize section names,
6236 but hack is temporarly out of order since it needs improvement.
6237 * _pic16_genAssemblerPreamble: configuration words are emitted by
6238 their address instead of their name. This part is incomplete and
6239 supports only the 18Fxx2 devices. Other devices will emit an error
6240 during assembly since they do not contain the same set of config
6242 * _pic16_genIVT: is modified,
6244 * pcode.c: added definitions for some hardware registers that are needed
6246 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6247 All PCI entries are updated. Now LFSR is supported.
6248 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6249 * added pic16_newpCodeOpLit2 to support instructions with
6250 two literal arguments
6251 * pic16_pCode2str: corrected code that emits assembler instructions
6252 with two literal operands and those that have an access bit modifier
6253 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6254 this fixes a bug which caused some labels to be lost, when an
6255 assembler directive was added, i.e. banksel,
6256 * pic16_FixRegisterBanking: improved logic that causes the insertion
6258 * InlineFunction: functions that are called once, are not any more
6259 inlined. This can be a port option in the future,
6261 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6263 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6264 hold the corresponding uninitialized symbols,
6265 * pic16_allocProcessorRegister: registers have explicit marked the
6267 * pic16_allocInternalRegister: registers are explicit marked as
6269 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6270 processing list, so bit registers were lost,
6273 * ralloc.h: added field 'accessBank' and original symbol operand
6274 in register definition,
6275 * removed the field isMapped from register definition,
6277 ** Several functions have been removed from various sources:
6278 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6279 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6280 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6281 pic16_assignRelocatableRegisters
6283 ** others have been introduced:
6284 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6285 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6287 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6289 * support/scripts/inc2h.pl: changed definition of BIT_AT
6290 to emit 'sbit at' instead of 'bit at'. This was a request.
6292 PIC16 port related preliminary changes:
6293 * gen.c: prefixed function popRegFromString with
6294 pic16_ and all references to it corrected
6295 * pcode.c: all pic16_pc_* hardware registers prefixed
6296 with underscore (_),
6297 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6298 * ralloc.c: newReg(): when register is REG_SFR then
6299 set address to rIdx,
6300 pic16_allocProcessorRegister(): marks register wasUsed=0
6301 pic16_writeUsedRegs(): added a call to assign processor
6302 registers via pic16_assignFixedRegisters
6304 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6306 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6307 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6308 variables in unused register banks. Also the SSEG is placed
6309 wherever there is enough space for it, and IDATA can be anywhere
6310 in internal RAM. For now compile using -Wl-Y[stack_size].
6311 The mem file is different for this option as well, since it
6312 makes no sense of talking about DSEG lenght.
6314 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6316 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6317 in certain cases, e.g. when ROM assignment, patch provided
6318 from Albert den Haan.
6320 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6463 * src/mcs51/peephole.def,
6464 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6476 multiply defined with mismatching "at" address.
6478 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6480 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

6559 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6561 * src/SDCCast.c (decorateType): disabled a transformation I added in
6562 revision 1.188 (access to fields of a structure at an absolute address);
6563 it breaks with bitfields, extern declarations, and gcse analysis.
6564 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6565 could be assigned through a pointer, so don't complain.
6566 * src/SDCCast.c (astErrors),
6568 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7206 support for standard C idiom of memory mapped variables; for
7207 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7208 to xdata int at 0x1234 tempvar = 1.
7209 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7210 provided by Akiya ISHIDA

7226 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7228 Fixed bug #621531 (const & volatile confusion in the type chain).
7229 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7230 refer to the const or volatile state of the pointer itself.

7321 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7322 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7323 fetching of the pointer
7324 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7325 copied from genNearPointerSet()
7326 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7327 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7328 If they pop r0/r1 they must be called in the opposite order than aopOp().
7329 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7330 (resp. --stack-auto), prepared for --xstack

7341 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7343 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7344 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7345 type for bits was changed. It resulted in bit variables becoming
7346 global, which is not permitted in PIC 14 assembly output.
7348 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7350 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7352 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7354 Z80 and MCS51 linkers complaint if a public symbol is defined

7363 A few small changes that speed up the peephole optimizer.
7367 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7369 Try to make the peephole optimizer smarter by maintaining
7370 an association between the assembly source code and the
7371 iCodes that originated them. Put this information to use
7372 with a new peephole rule condition "notVolatile" so that
7373 the rules can be aggressive yet still safe.
7378 * src/mcs51/peeph.def
7380 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7384 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7385 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7386 if the left or right operand symbols have the accuse flag set.
7388 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7390 Changed the type of the result of the ! (NOT) operator to char;
7391 previously it returned the same type as the source. This allows
7392 us to eliminate all the genFloatNot functions (all of its target
7393 implementations were very buggy) since !float can use the same
7396 * src/SDCCicode.c (ast2iCode): ! returns char

7405 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7406 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7407 during interrupts. Ensure WSAVE is located at a shared bank address.
7408 2. Fixed page selection in some places
7409 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7410 the registers name strings.
7411 4. Fixed "signed / unsigned compare" compiler warnings.
7412 5. The PIC port manages its own allocation of the general purpose
7413 registers, but makes no attempt to reuse them. As a result when
7414 compiling it soon runs out of general purpose registers. Some
7415 additional code was added to the files pcode.c and device.c to walk
7416 through the function call tree and rename the registers so that they
7426 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7427 genPlus() & genMinus() when the result is the same as left or right
7429 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7433 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7435 Made bitfield a distinct type from bit so that bitfields
7436 convert as per ANSI C and bits retain their traditional
7437 boolean style behaviour. Implemented bitfield support in
7445 * src/ds390/gen.c: bit v bitfield split
7446 * src/z80/gen.c: New support for bitfields
7447 * support/regression/tests/bitfields.c: reenabled z80,
7450 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7452 Rules 246.x, 247.x relate to bitfields, the others speed up
7453 access to xdata mapped I/O devices.
7455 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7457 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7459 Cleaned up genPackBits and genUnpackBits and added two helper
7460 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7461 for literal assignments in genPackBits (thanks to Frieder for
7467 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7469 Fixed bug #748310 (pointer to function type mishandled when the
7470 function name is omitted). Also fixed a SIGSEGV when a function
7471 attribute (reentrant, etc) is used on a non-function or on a
7472 function but misplaced before the parameter list.
7474 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7476 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7477 * support/Util/SDCCerr.h,
7478 * support/Util/SDCCerr.c: Added func attr misuse error msg

7499 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7501 Made the constant following the "interrupt" keyword optional. If
7502 omitted, the function will not automatically be given an entry
7503 in the interrupt vector table (similar to #pragma NOIV, but
7504 less syntacticly kludgy). The interrupt number is also now
7505 range checked. Also fixed a bug in the high order bit example

7519 * src/SDCCicode.c (operandOperation): rewritten some ops
7520 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7521 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7523 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7524 be re-activated by defining REDUCE_LITERALS)
7525 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7526 unsigned, but are signed by default
7527 * src/SDCCval.c (constVal): rearranged
7528 * src/SDCCval.c (valMod): preliminary fix
7529 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7571 constants are unsigned; added recognition of "u" flag for unsigned
7572 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7573 * src/SDCCval.c (valDiv, valMod): fixed signdness
7574 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7575 signedness of modulo, left and right shift

8035 added if/endif conditional macros to remove options help
8036 messages from optionsTable when a port is not configured, added
8037 support for the PIc16 port in the ports table, when executing
8038 the compiler with no port specified on command line, a default
8039 port is selected with the new macro DEFAULT_PORT which is
8040 defined in port.h, in setDefaultOptions() linkOptions is removed
8041 from initialization assignment, since now it is a set,
8042 parseCmdLine uses setParseWithComma for linkOptions, in
8043 linkEdit() linkOptions are accessed with new function indexSet()
8044 which returns the i'th item of a set variable. See SDCCset.c, in
8045 linkEdit() when calling buildCmdLine(), added linkOptions as
8046 last argument. Now users can pass arguments to gplink via the
8047 -Wl option, main() uses pic16glue() to glue up pic16 programs

8061 gpasm complaining and test the linkage with gplink, _linkCmd and
8062 _asmCmd changed to be more gplink and gpasm friendly
8063 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8064 produced an error when parsed, peep rule 12 is added to utilize
8065 movff, but it is commented out since the pCode does not support
8066 yet a command with 2 address arguments
8068 2003-05-18 <johan AT balder>
8070 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8097 2003-05-11 Borut Razem <borut.razem AT siol.net>
8099 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9090 * src/SDCCast.c (decorateType): fixed bug #600035
9092 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9093 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9094 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9095 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

9097 * src/pic/ralloc.c: outcommented unused variable to remove warnings
9099 2003-01-06 <karl AT turbobit.com>
9100 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9103 2003-01-06 <johan AT balder>
9105 * src/SDCCicode.c: fixed array add
9107 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9108 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9109 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9111 2003-01-04 <johan AT balder>
9113 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9115 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9116 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9118 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9119 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9120 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9122 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9123 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9125 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9126 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9128 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9129 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9131 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9133 * in \sdcc\as\mcs51\ changed these files in order to create an
9134 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9135 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9136 following files to include the previous two files: aslink.dsp,
9137 Makefile.aslink, Makefile.bcc, and Makefile.in.
9139 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9140 .adb instead of .cdb
9142 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9144 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9145 value from option --iram-size.
9147 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9149 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9152 2002-09-18 <wiml AT hhhh.org>
9154 * SDCClrange.h: exposed setFromRange() and setToRange()
9155 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9156 packRegsForAccUse() (bug 542397)
9157 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9158 multiple times and emitting the fetch operations more than once
9159 added aopGetUsesAcc() function to allow binary operators to
9160 fetch their operands in the correct order; made genMinus() emit
9161 compact code for X = LITERAL - Y
9163 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9164 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9165 sprintf() in line 1267.
9167 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9168 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9171 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9172 Changes to aslink (All the changes are marked with 'JCF'):
9174 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9177 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9178 area BSEG. Also moves, if possible, the DATA area down into the internal
9179 ram so more space is available.
9181 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9184 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9185 not bytes. Function summary() which creates a memory usage summary
9186 file with extension .mem. Reports of overlaping stack and small stack
9187 size. If the space for the stack is less than 16 bytes aslink trows a
9190 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9191 the 8051. Option 'y' for memory summary output file.
9193 Changes to sdcc (All the changes are marked with 'JCF'):
9195 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9197 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9198 overlaying area for it (uses RegBankUsed[4]).
9200 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9201 bank zero as used by default. By default aslink locates the stack
9202 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9203 the creation of the .mem file. Delegates the allocation of data area
9204 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9205 the begining of the stack area to aslink.
9207 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9208 glue() in SDCCglue.c creates an area for it.
9210 2002-09-03 Borut Razem <borut.razem AT siol.net>
9211 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9212 sdcc/src/pic/glue.c:
9213 introduced atexit() handler for teporay files removal in case of
9214 errors, assertions, ...
9216 2002-08-29 Borut Razem <borut.razem AT siol.net>
9217 * sdcc/support/cpp2/auto-host_vc_in.h:
9218 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9219 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9220 Maybe there is a similar problem with BORLANDC? It should be checked!
9222 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9223 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9224 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9225 was not executed, and the compiler (cl) launched a warning:
9226 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9228 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9229 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9231 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9232 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9234 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9235 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9236 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9237 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9238 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9239 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9240 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9241 - added Release configuration in VS projects
9242 - review of compiler an linker options
9243 - VC .exe files are generated in bin_vc directory, not to interfere
9244 with binaries generated from other projects (cygwin, mingw, bcc ...)
9246 * sdcc/src/yacc.dsp: added
9248 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9249 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9250 and insert the version number definitions from .version
9252 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9254 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9255 added - genarate auto-host.h using auto-host_vc_in.h as template
9258 removed from CVS, generated automatically
9260 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9261 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9263 2002-08-11 Borut Razem <borut.razem AT siol.net>
9264 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9266 2002-08-10 Borut Razem <borut.razem AT siol.net>
9267 * src/SDCCmain.c (main):
9268 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9269 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9270 The consequence was that some temporary files were not removed.
9273 unification of code in functions tempfilename() and tempfile():
9274 function tempnam() is defined in Visual Studio 6.0 and .NET
9276 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9278 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9279 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9280 - removed compiler command line option /WX: Treats all warnings as errors
9281 - update a list of source files, included into the project
9283 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9284 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9285 changed project type to Generic Project so that can be correcly converted to VS.NET project
9287 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9289 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9291 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9293 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9294 added return 0 statements after assert() to make compiler happy
9296 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9297 added newline in the def file to keep MSC compiler satisfied
9299 * sdcc/src/z80/gen.c:
9300 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9301 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9302 - solved MSC error in function aopDump()
9304 * sdcc_vc.h: define PREFIX as "\\sdcc"
9306 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9307 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9309 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9310 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9311 - Rewrote the register banking algorithm.
9312 - Added pCode live-range analysis to registers (for now, only non-used and
9313 singly-used registers optimized away)
9315 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9317 * 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.

9342 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9344 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9346 2002-03-28 Johan Knol <johan AT balder>
9348 * src/SDCCval.c: fixed bug #532436
9350 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9352 Added "char *Processor" field to the port structure.
9355 Added -p option. Allows port dependent processor to be specified.
9358 Initialized the new field char *Processor field to NULL in all ports
9361 Compiler generated registers for interrupt context saving
9362 were not getting allocated.
9364 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9367 Fixed left shift. Will promote the left side of a left shift
9368 if a) left shifting more than size of operand or b) when assigned
9369 to something size > size of left side
9371 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9373 tons of changes. Register allocation has been
9374 rewritten. Added customization for the various PICs. Flow
9375 analysis is restructured. ...
9381 Added. device.c is a PIC port hack to accomodate variations
9384 2002-03-13 Michael Hope <michaelh AT vroom>
9386 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9388 2002-03-04 johanknol <johanknol AT manik>
9390 * /src/SDCCval.c: fixed
9392 const unsigned char arr[][2] = { { 0, 1 } };
9393 t18.c:1: error: Initializer element is not constant
9395 2002-03-04 bela <bela AT manik>
9397 * /device/include/mcs51reg.h:
9398 ds89c420 register definition update
9400 2002-03-03 <johan AT FRIJA>

9479 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9481 * sdcc/src/SDCCloop.c:
9482 Previous fix was not good. basic blocks that have "break" or "return" are
9483 not really partof a loop , but live ranges used in these blocks should
9484 be live thru the entire loop, so set partOfLoop but don't add them to
9487 2002-02-21 <johan AT FRIJA>
9489 * src/SDCCcse.c: fixed bug #514308
9491 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9494 Fixed BUG #519583. If a conditional block ended in a return/break
9495 statement inside a loop, it was not being considered part of the loop.
9497 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9499 2002-02-10 Karl Bongers <karl AT turbobit.com>
9502 Fixed up SDCDB debugger somewhat. Updated debugger/README
9503 with lots of comments and notes.
9505 * device/examples/test2.c:
9506 Fix bug, "red" variable not being initialized(compiler complained).
9508 * device/examples/Makefile, examples/test3.c:
9509 Add Makefile in device/examples folder, compiles test3.c
9510 for use as a multiple module SDCDB test case.
9512 * sim/ucsim/cmd.src/cmdset.cc:
9513 Took out debug printfs in ucsim "next" command.
9516 Karl and Johan start ucsim XA support. Most dissassembly working,
9517 about 75% emulation done(plenty of work remaining).
9519 * sim/ucsim/z80.src:
9520 Add Z80 support to ucsim, add test-ucz80 regression test,
9521 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9522 Notice z80 compiler fails on examples/test3.c/crc code.
9524 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

9534 from a memory mapped port
9535 2) added __builtin_memcmp
9536 3) added __builtin_swapw swap bytes of a short
9538 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9539 1) handle multiple send & receives from register bank1
9540 2) ralloc can now allocate DPTR1 to some liveRanges
9542 * src/SDCCsymt.c, src/SDCCsymt.h:
9543 changes to handle multiple sends & receives
9546 added some pointer arithmetic optimization
9549 added some pointer arithmetic optimizations but not stable yet so not
9550 called from anywhere (will get this working shortly)
9552 * src/SDCCopt.c: fixed for multiple sends & receives
9555 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9556 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9557 set preprocessor defines (depending on options)
9559 * src/SDCCicode.c, src/SDCCicode.h:
9560 changes made to handle multiple sends & receives
9563 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
