1950 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1951 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1952 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1953 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1954 always available in leading double underscore form. The C99 support is

2035 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2037 * device/lib/printf_large.c: removed inline assembly for portability and
2038 readability. Use printf_fast if speed or size are more important.
2039 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2040 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2042 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2044 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2045 prevent compiler warning
2047 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2049 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2050 moved to level 0 and declared as static. Also they are explicit
2051 placed in access bank. This was necessery because some times they
2052 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2053 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2054 optimizations. Currently only compare to unsigned char is implemented,
2055 * src/pic16/gen.c: added fReturnIdx array,
2056 * (struct resolvedIfx) is moved to gen.h and made public,
2057 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2058 * (aopForSym): added an optimization to directly store in stack of
2059 the operand of a SEND iCode,
2060 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2061 but as registers instead (AOP_REG) using the fReturnIdx array,
2062 * (pic16_freeAsmop): remove the freed register from the
2063 _G.sregsAlloc field,
2064 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2065 a compare of 'WREG',
2066 * (pic16_popGetTempRegCond): changed function prototype, now
2067 function takes also a bitVector argument v which holds the current
2068 set of registers that are allocated for stack access by aopForSym,
2069 registers allocated in aopForSym for accessing stack symbols are not
2070 any more part of the functions usedRegs field,
2071 * (genCall): some times aopOp is called for a stack variable to be
2072 send, aopForSym might perform the push, if this is true make sure
2073 that genCall doesn't push the variable twice by testing _G.resDirect,
2074 * (genFunction): changed testing for unspecified interrupt number
2075 from 256 to INTNO_UNSPEC,
2076 * modified selection scheme of frame pointer generation. Previously
2077 if function did use local registers a frame pointer was generated,
2078 now a frame pointer is generated only if function has arguments
2079 (that need PLUSW2 register access), or has stack arguments, or the
2080 compiler is not instructed to omit the frame pointer,
2081 * (genEndFunction): before restoring local registers that were saved
2082 in the function preamble, also restore the registers that *might*
2083 have been allocated for stack access,
2084 * (genRet): removed some old comments,
2085 * (genCmp, the active (RN's) version): added a call to the
2086 pic16_genCmp_special function to perform the compare with a more
2087 robust and optimized way,
2088 * (genInline): a feature has been added in inline code generation,
2089 which allows a wildcard variable substitution when writing inline
2090 assembly. Code is incomplete and experimental therefore undocumented,
2091 * (genCast): changed order of aopOp for result and right to allow
2092 aopForSym to directly load the result if possible,
2093 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2094 perform an optimized compare on some selected special occasions,
2095 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2096 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2097 generate an IVT any more,
2098 * src/pic16/main.c (pic16_optionsTable): added command line option
2100 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2101 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2103 * src/pic16/NOTES: Raphael Neider added in list of active developers
2104 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2105 jumptable_end to prevent bug #,
2106 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2107 inCond and outCond fields,
2108 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2109 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2110 turn off register spilling,
2111 * (packRegsForOneUse): synced with other ports' versions although it
2112 is not used currently,
2113 * (pic16_packRegisters): added an optimization while reading
2114 structure bitfields, some registers may be saved (malloc code is
2115 decreased by 80 bytes)
2117 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2119 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2120 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2121 this can be optimized more?
2123 2005-03-10 Raphael Neider <rneider AT web.de>
2125 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2126 genNearPointerGet): (hopefully) fixed access to bitfields via
2127 pointers (p->bitN = x; and x = p->bitN; failed)
2129 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2131 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2143 * support/regression/tests/critical.c: check bug 1144613
2145 2005-03-02 Raphael Neider <rneider AT web.de>

2761 Adding support for replacing ljmps with sjmps in jumptables
2762 generated for switch statements. For now you need to set the
2763 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2764 Now 4 algorithms for mcs51 jumptable generation are used:
2765 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2766 addresses loaded pc-relative for up to 112 cases and stack-pushing
2767 target addresses loaded with offset from dptr for up to 256 cases.

2797 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2799 * added libc directory. The current version of LibC contains string
2800 functions, ctype functions and macros and some functions of the
2801 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2802 be extensively tested in the future. Standard disclaimer here.
2803 Library is not automatically build yet. But one can build it by
2804 invoking 'make' inside the libc directory.
2805 * added ADC library under libio. Preliminary version yet.

2814 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2815 * (pic16_storeForReturn): optimized return of 0,
2816 * (genCmp): experimental code for new genCmp which uses PIC18's
2817 special compare&skip instructions. Initial tests fail some times
2818 with variables grater than 1 byte in size, so new code is disabled,
2819 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2821 * (genCast): began a fix to optimize the casting of a bit to another
2822 bit, now assigning a bitfield to another bitfield will fail, sorry,
2823 * src/pic16/main.c: disabled the use of lr-support feature,
2824 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2831 and 1 for banking instruction,
2832 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2833 caused stop processing pCodes after a inline assembly block,
2834 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2835 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2836 registers when it shouldn't,
2837 * src/pic16/ralloc.c (allocReg): add preliminary support for
2838 supporting a limited set of temporary registers,
2840 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2842 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2843 genDataPointerSet): ensure assignments always copy in MSB to LSB
2845 (loadRegFromAop): recognize CLRH optimization,
2846 (genFunction): optimize RECEIVE iCodes in reentrant functions
2848 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2850 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5848 loaded with the linker search paths (-L arguments) and the libraries
5849 to be linked with the current source (-l arguments). Changes
5850 currently will affect only the pic16 port.
5851 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5852 include path the port specific paths and port specific libraries,
5853 * gplink command now contains the $3 argument,

5871 Documenting changes from previous commits.
5872 * configure.in (version 1.56),
5873 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5874 when generating output files to configure the pic16 library,
5875 but now I've commented it out, since gputils aren't installed in the
5876 SF compile farm, so library won't compile
5878 * device/lib/Makefile.in (version 1.56): initially I've added in
5879 target 'all' the prerequestive 'model-pic16' so it compiled the
5880 pic16 library, but now I've commented it out for the same reasons
5882 * added targets 'model-pic16' and 'objects-pic16' to compile the
5884 * added target 'port-specific-objects-pic16' to handle the
5885 generated libraries and copy them into the build/ directory
5886 * added target 'clean-intermediate-pic16' to clean intermediate
5887 files into pic16 directory
5888 * in target 'installdirs' added line to create directory pic16 in

6166 Bug reported from Jesus Calvino-Fraga
6168 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6170 * sdcc.spec: updated
6171 * device/include/Makefile.in: don't install CVS directories
6172 * device/lib/Makefile.in: added removal of CVS directories after install
6173 * doc/Makefile: fixed install, added local_icons
6174 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6175 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6176 * src/ds390/gen.c (genRightShift): fixed bug #870788
6177 * src/SDCCast.c (decorateType): fixed bug #870781
6179 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6181 PIC16 port related changes:
6182 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6183 added variable stackPos,
6185 * gen.c: genCall, assignResultValue: added support for
6186 pushing/retrieving function parameters to/from stack,
6187 genFunction,genEndFunction: setup stack frame for the
6189 genAddrOf: will be changed according to bug 863624
6191 * added files genutils.c and genutils.h which contain gen*
6192 debugged and optimised functions extracted from gen.c
6194 * glue.c: added variable 'externs' which holds extern symbols,
6195 pic16emitRegularMap: is modified to properly handle relocatable
6196 symbols under the new scheme,
6197 pic16createInterruptVect: is modified
6198 pic16printPublics: is modified to emit 'global' assembler directives,
6199 added pic16_printExterns to print extern symbols,
6200 pic16glue: initializes stack/frame pointer in the beginning of
6201 the assembly output. Temporary hack, will be corrected later,
6202 because gplink yet does not support stack and SDCC does not
6203 yet support a type of crt0.o object to create the final binary.
6205 * Removed many lines that contain 8051 legacy code.
6206 * The code is finally placed under a 'code' directive.
6207 * Added port specific options.
6209 * _process_pragma: simplified since now we do not need *special*
6210 include file to define SFR registers. But a separate header
6211 will be needed. This will be developed later.
6212 * _pic16_parseOptions: added, parses port specific options:
6213 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6214 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6215 --preplace-udata-with=
6217 * _pic16_setDefaultOptions: modified to initialize section names,
6218 but hack is temporarly out of order since it needs improvement.
6219 * _pic16_genAssemblerPreamble: configuration words are emitted by
6220 their address instead of their name. This part is incomplete and
6221 supports only the 18Fxx2 devices. Other devices will emit an error
6222 during assembly since they do not contain the same set of config
6224 * _pic16_genIVT: is modified,
6226 * pcode.c: added definitions for some hardware registers that are needed
6228 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6229 All PCI entries are updated. Now LFSR is supported.
6230 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6231 * added pic16_newpCodeOpLit2 to support instructions with
6232 two literal arguments
6233 * pic16_pCode2str: corrected code that emits assembler instructions
6234 with two literal operands and those that have an access bit modifier
6235 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6236 this fixes a bug which caused some labels to be lost, when an
6237 assembler directive was added, i.e. banksel,
6238 * pic16_FixRegisterBanking: improved logic that causes the insertion
6240 * InlineFunction: functions that are called once, are not any more
6241 inlined. This can be a port option in the future,
6243 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6245 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6246 hold the corresponding uninitialized symbols,
6247 * pic16_allocProcessorRegister: registers have explicit marked the
6249 * pic16_allocInternalRegister: registers are explicit marked as
6251 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6252 processing list, so bit registers were lost,
6255 * ralloc.h: added field 'accessBank' and original symbol operand
6256 in register definition,
6257 * removed the field isMapped from register definition,
6259 ** Several functions have been removed from various sources:
6260 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6261 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6262 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6263 pic16_assignRelocatableRegisters
6265 ** others have been introduced:
6266 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6267 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6269 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6271 * support/scripts/inc2h.pl: changed definition of BIT_AT
6272 to emit 'sbit at' instead of 'bit at'. This was a request.
6274 PIC16 port related preliminary changes:
6275 * gen.c: prefixed function popRegFromString with
6276 pic16_ and all references to it corrected
6277 * pcode.c: all pic16_pc_* hardware registers prefixed
6278 with underscore (_),
6279 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6280 * ralloc.c: newReg(): when register is REG_SFR then
6281 set address to rIdx,
6282 pic16_allocProcessorRegister(): marks register wasUsed=0
6283 pic16_writeUsedRegs(): added a call to assign processor
6284 registers via pic16_assignFixedRegisters
6286 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6288 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6289 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6290 variables in unused register banks. Also the SSEG is placed
6291 wherever there is enough space for it, and IDATA can be anywhere
6292 in internal RAM. For now compile using -Wl-Y[stack_size].
6293 The mem file is different for this option as well, since it
6294 makes no sense of talking about DSEG lenght.
6296 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6298 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6299 in certain cases, e.g. when ROM assignment, patch provided
6300 from Albert den Haan.
6302 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6445 * src/mcs51/peephole.def,
6446 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6458 multiply defined with mismatching "at" address.
6460 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6462 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
6463 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

6541 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6543 * src/SDCCast.c (decorateType): disabled a transformation I added in
6544 revision 1.188 (access to fields of a structure at an absolute address);
6545 it breaks with bitfields, extern declarations, and gcse analysis.
6546 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6547 could be assigned through a pointer, so don't complain.
6548 * src/SDCCast.c (astErrors),
6550 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7188 support for standard C idiom of memory mapped variables; for
7189 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7190 to xdata int at 0x1234 tempvar = 1.
7191 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7192 provided by Akiya ISHIDA

7208 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7210 Fixed bug #621531 (const & volatile confusion in the type chain).
7211 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7212 refer to the const or volatile state of the pointer itself.

7277 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7278 pcoderegs.h, ralloc.c, ralloc.h
7279 * main.c: added top header and GPL license notice

7303 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7304 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7305 fetching of the pointer
7306 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7307 copied from genNearPointerSet()
7308 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7309 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7310 If they pop r0/r1 they must be called in the opposite order than aopOp().
7311 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7312 (resp. --stack-auto), prepared for --xstack

7323 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7325 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7326 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7327 type for bits was changed. It resulted in bit variables becoming
7328 global, which is not permitted in PIC 14 assembly output.
7330 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7332 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7345 A few small changes that speed up the peephole optimizer.
7349 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7351 Try to make the peephole optimizer smarter by maintaining
7352 an association between the assembly source code and the
7353 iCodes that originated them. Put this information to use
7354 with a new peephole rule condition "notVolatile" so that
7355 the rules can be aggressive yet still safe.
7360 * src/mcs51/peeph.def
7362 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7366 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7367 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7368 if the left or right operand symbols have the accuse flag set.
7370 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7372 Changed the type of the result of the ! (NOT) operator to char;
7373 previously it returned the same type as the source. This allows
7374 us to eliminate all the genFloatNot functions (all of its target
7375 implementations were very buggy) since !float can use the same

7387 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7388 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7389 during interrupts. Ensure WSAVE is located at a shared bank address.
7390 2. Fixed page selection in some places
7391 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7392 the registers name strings.
7393 4. Fixed "signed / unsigned compare" compiler warnings.
7394 5. The PIC port manages its own allocation of the general purpose
7395 registers, but makes no attempt to reuse them. As a result when
7396 compiling it soon runs out of general purpose registers. Some
7397 additional code was added to the files pcode.c and device.c to walk
7398 through the function call tree and rename the registers so that they
7408 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7409 genPlus() & genMinus() when the result is the same as left or right

7415 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7417 Made bitfield a distinct type from bit so that bitfields
7418 convert as per ANSI C and bits retain their traditional
7419 boolean style behaviour. Implemented bitfield support in
7427 * src/ds390/gen.c: bit v bitfield split
7428 * src/z80/gen.c: New support for bitfields
7429 * support/regression/tests/bitfields.c: reenabled z80,
7432 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7434 Rules 246.x, 247.x relate to bitfields, the others speed up
7435 access to xdata mapped I/O devices.
7437 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7439 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7441 Cleaned up genPackBits and genUnpackBits and added two helper
7442 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7443 for literal assignments in genPackBits (thanks to Frieder for
7449 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7451 Fixed bug #748310 (pointer to function type mishandled when the
7452 function name is omitted). Also fixed a SIGSEGV when a function
7453 attribute (reentrant, etc) is used on a non-function or on a
7454 function but misplaced before the parameter list.
7456 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7458 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7459 * support/Util/SDCCerr.h,
7460 * support/Util/SDCCerr.c: Added func attr misuse error msg

7481 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7483 Made the constant following the "interrupt" keyword optional. If
7484 omitted, the function will not automatically be given an entry
7485 in the interrupt vector table (similar to #pragma NOIV, but
7486 less syntacticly kludgy). The interrupt number is also now
7487 range checked. Also fixed a bug in the high order bit example

7501 * src/SDCCicode.c (operandOperation): rewritten some ops
7502 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7503 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7505 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7506 be re-activated by defining REDUCE_LITERALS)
7507 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7508 unsigned, but are signed by default
7509 * src/SDCCval.c (constVal): rearranged
7510 * src/SDCCval.c (valMod): preliminary fix
7511 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8016 * src/SDCCmain.c: linkOptions is changed to set *,
8017 added if/endif conditional macros to remove options help
8018 messages from optionsTable when a port is not configured, added
8019 support for the PIc16 port in the ports table, when executing
8020 the compiler with no port specified on command line, a default
8021 port is selected with the new macro DEFAULT_PORT which is
8022 defined in port.h, in setDefaultOptions() linkOptions is removed
8023 from initialization assignment, since now it is a set,
8024 parseCmdLine uses setParseWithComma for linkOptions, in
8025 linkEdit() linkOptions are accessed with new function indexSet()
8026 which returns the i'th item of a set variable. See SDCCset.c, in
8027 linkEdit() when calling buildCmdLine(), added linkOptions as
8028 last argument. Now users can pass arguments to gplink via the
8029 -Wl option, main() uses pic16glue() to glue up pic16 programs

8043 gpasm complaining and test the linkage with gplink, _linkCmd and
8044 _asmCmd changed to be more gplink and gpasm friendly
8045 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8046 produced an error when parsed, peep rule 12 is added to utilize
8047 movff, but it is commented out since the pCode does not support
8048 yet a command with 2 address arguments
8050 2003-05-18 <johan AT balder>
8052 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8079 2003-05-11 Borut Razem <borut.razem AT siol.net>
8081 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8082 the path of bin directory, so that PATH is the only env. variable, which has to be set

9093 2003-01-04 <johan AT balder>
9095 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9097 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9098 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9100 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9101 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9102 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9104 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9105 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9107 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9108 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9110 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9111 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9113 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9115 * in \sdcc\as\mcs51\ changed these files in order to create an
9116 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9117 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9118 following files to include the previous two files: aslink.dsp,
9119 Makefile.aslink, Makefile.bcc, and Makefile.in.
9121 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9122 .adb instead of .cdb
9124 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9126 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9127 value from option --iram-size.
9129 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9131 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9134 2002-09-18 <wiml AT hhhh.org>
9136 * SDCClrange.h: exposed setFromRange() and setToRange()
9137 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9138 packRegsForAccUse() (bug 542397)
9139 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9140 multiple times and emitting the fetch operations more than once
9141 added aopGetUsesAcc() function to allow binary operators to
9142 fetch their operands in the correct order; made genMinus() emit
9143 compact code for X = LITERAL - Y
9145 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9146 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9147 sprintf() in line 1267.
9149 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9150 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9153 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9154 Changes to aslink (All the changes are marked with 'JCF'):
9156 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9159 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9160 area BSEG. Also moves, if possible, the DATA area down into the internal
9161 ram so more space is available.
9163 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9166 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9167 not bytes. Function summary() which creates a memory usage summary
9168 file with extension .mem. Reports of overlaping stack and small stack
9169 size. If the space for the stack is less than 16 bytes aslink trows a
9172 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9173 the 8051. Option 'y' for memory summary output file.
9175 Changes to sdcc (All the changes are marked with 'JCF'):
9177 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9179 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9180 overlaying area for it (uses RegBankUsed[4]).
9182 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9183 bank zero as used by default. By default aslink locates the stack
9184 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9185 the creation of the .mem file. Delegates the allocation of data area
9186 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9187 the begining of the stack area to aslink.
9189 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9190 glue() in SDCCglue.c creates an area for it.
9192 2002-09-03 Borut Razem <borut.razem AT siol.net>
9193 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9194 sdcc/src/pic/glue.c:
9195 introduced atexit() handler for teporay files removal in case of
9196 errors, assertions, ...
9198 2002-08-29 Borut Razem <borut.razem AT siol.net>
9199 * sdcc/support/cpp2/auto-host_vc_in.h:
9200 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9201 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9202 Maybe there is a similar problem with BORLANDC? It should be checked!
9204 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9205 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9206 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9207 was not executed, and the compiler (cl) launched a warning:
9208 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9210 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9211 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9213 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9214 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9216 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9217 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9218 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9219 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9220 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9221 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9222 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9223 - added Release configuration in VS projects
9224 - review of compiler an linker options
9225 - VC .exe files are generated in bin_vc directory, not to interfere
9226 with binaries generated from other projects (cygwin, mingw, bcc ...)
9228 * sdcc/src/yacc.dsp: added
9230 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9231 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9232 and insert the version number definitions from .version
9234 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9236 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9237 added - genarate auto-host.h using auto-host_vc_in.h as template
9240 removed from CVS, generated automatically
9242 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9243 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9245 2002-08-11 Borut Razem <borut.razem AT siol.net>
9246 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9248 2002-08-10 Borut Razem <borut.razem AT siol.net>
9249 * src/SDCCmain.c (main):
9250 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9251 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9252 The consequence was that some temporary files were not removed.
9255 unification of code in functions tempfilename() and tempfile():
9256 function tempnam() is defined in Visual Studio 6.0 and .NET
9258 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9260 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9261 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9262 - removed compiler command line option /WX: Treats all warnings as errors
9263 - update a list of source files, included into the project
9265 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9266 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9267 changed project type to Generic Project so that can be correcly converted to VS.NET project
9269 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9271 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9273 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9275 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9276 added return 0 statements after assert() to make compiler happy
9278 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9279 added newline in the def file to keep MSC compiler satisfied
9281 * sdcc/src/z80/gen.c:
9282 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9283 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9284 - solved MSC error in function aopDump()
9286 * sdcc_vc.h: define PREFIX as "\\sdcc"
9288 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9289 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9291 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9292 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9293 - Rewrote the register banking algorithm.
9294 - Added pCode live-range analysis to registers (for now, only non-used and
9295 singly-used registers optimized away)
9297 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9299 * 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.

9328 2002-03-28 Johan Knol <johan AT balder>
9330 * src/SDCCval.c: fixed bug #532436
9332 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9334 Added "char *Processor" field to the port structure.
9337 Added -p option. Allows port dependent processor to be specified.
9340 Initialized the new field char *Processor field to NULL in all ports
9343 Compiler generated registers for interrupt context saving
9344 were not getting allocated.
9346 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9349 Fixed left shift. Will promote the left side of a left shift
9350 if a) left shifting more than size of operand or b) when assigned
9351 to something size > size of left side
9353 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9355 tons of changes. Register allocation has been
9356 rewritten. Added customization for the various PICs. Flow
9357 analysis is restructured. ...
9363 Added. device.c is a PIC port hack to accomodate variations
9366 2002-03-13 Michael Hope <michaelh AT vroom>
9368 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9377 2002-03-04 bela <bela AT manik>
9379 * /device/include/mcs51reg.h:
9380 ds89c420 register definition update
9382 2002-03-03 <johan AT FRIJA>

9461 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9463 * sdcc/src/SDCCloop.c:
9464 Previous fix was not good. basic blocks that have "break" or "return" are
9465 not really partof a loop , but live ranges used in these blocks should
9466 be live thru the entire loop, so set partOfLoop but don't add them to
9469 2002-02-21 <johan AT FRIJA>
9471 * src/SDCCcse.c: fixed bug #514308
9473 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9476 Fixed BUG #519583. If a conditional block ended in a return/break
9477 statement inside a loop, it was not being considered part of the loop.
9479 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9481 2002-02-10 Karl Bongers <karl AT turbobit.com>
9484 Fixed up SDCDB debugger somewhat. Updated debugger/README
9485 with lots of comments and notes.
9487 * device/examples/test2.c:
9488 Fix bug, "red" variable not being initialized(compiler complained).
9490 * device/examples/Makefile, examples/test3.c:
9491 Add Makefile in device/examples folder, compiles test3.c
9492 for use as a multiple module SDCDB test case.
9494 * sim/ucsim/cmd.src/cmdset.cc:
9495 Took out debug printfs in ucsim "next" command.
9498 Karl and Johan start ucsim XA support. Most dissassembly working,
9499 about 75% emulation done(plenty of work remaining).
9501 * sim/ucsim/z80.src:
9502 Add Z80 support to ucsim, add test-ucz80 regression test,
9503 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9504 Notice z80 compiler fails on examples/test3.c/crc code.

9537 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9538 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9539 set preprocessor defines (depending on options)
9541 * src/SDCCicode.c, src/SDCCicode.h:
9542 changes made to handle multiple sends & receives
9545 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
