1102 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1103 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1104 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1105 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1106 always available in leading double underscore form. The C99 support is
1107 mostly missing, but it's a start.
1108 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1109 reserved identifier "__data".

1187 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1189 * device/lib/printf_large.c: removed inline assembly for portability and
1190 readability. Use printf_fast if speed or size are more important.
1191 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1192 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1194 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1196 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1197 prevent compiler warning
1199 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1201 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1202 moved to level 0 and declared as static. Also they are explicit
1203 placed in access bank. This was necessery because some times they
1204 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1205 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1206 optimizations. Currently only compare to unsigned char is implemented,
1207 * src/pic16/gen.c: added fReturnIdx array,
1208 * (struct resolvedIfx) is moved to gen.h and made public,
1209 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1210 * (aopForSym): added an optimization to directly store in stack of
1211 the operand of a SEND iCode,
1212 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1213 but as registers instead (AOP_REG) using the fReturnIdx array,
1214 * (pic16_freeAsmop): remove the freed register from the
1215 _G.sregsAlloc field,
1216 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1217 a compare of 'WREG',
1218 * (pic16_popGetTempRegCond): changed function prototype, now
1219 function takes also a bitVector argument v which holds the current
1220 set of registers that are allocated for stack access by aopForSym,
1221 registers allocated in aopForSym for accessing stack symbols are not
1222 any more part of the functions usedRegs field,
1223 * (genCall): some times aopOp is called for a stack variable to be
1224 send, aopForSym might perform the push, if this is true make sure
1225 that genCall doesn't push the variable twice by testing _G.resDirect,
1226 * (genFunction): changed testing for unspecified interrupt number
1227 from 256 to INTNO_UNSPEC,
1228 * modified selection scheme of frame pointer generation. Previously
1229 if function did use local registers a frame pointer was generated,
1230 now a frame pointer is generated only if function has arguments
1231 (that need PLUSW2 register access), or has stack arguments, or the
1232 compiler is not instructed to omit the frame pointer,
1233 * (genEndFunction): before restoring local registers that were saved
1234 in the function preamble, also restore the registers that *might*
1235 have been allocated for stack access,
1236 * (genRet): removed some old comments,
1237 * (genCmp, the active (RN's) version): added a call to the
1238 pic16_genCmp_special function to perform the compare with a more
1239 robust and optimized way,
1240 * (genInline): a feature has been added in inline code generation,
1241 which allows a wildcard variable substitution when writing inline
1242 assembly. Code is incomplete and experimental therefore undocumented,
1243 * (genCast): changed order of aopOp for result and right to allow
1244 aopForSym to directly load the result if possible,
1245 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1246 perform an optimized compare on some selected special occasions,
1247 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1248 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1249 generate an IVT any more,
1250 * src/pic16/main.c (pic16_optionsTable): added command line option
1252 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1253 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1255 * src/pic16/NOTES: Raphael Neider added in list of active developers
1256 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1257 jumptable_end to prevent bug #,
1258 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1259 inCond and outCond fields,
1260 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1261 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1262 turn off register spilling,
1263 * (packRegsForOneUse): synced with other ports' versions although it
1264 is not used currently,
1265 * (pic16_packRegisters): added an optimization while reading
1266 structure bitfields, some registers may be saved (malloc code is
1267 decreased by 80 bytes)
1269 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1271 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1272 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1273 this can be optimized more?
1275 2005-03-10 Raphael Neider <rneider AT web.de>
1277 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1278 genNearPointerGet): (hopefully) fixed access to bitfields via
1279 pointers (p->bitN = x; and x = p->bitN; failed)
1281 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1283 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1913 Adding support for replacing ljmps with sjmps in jumptables
1914 generated for switch statements. For now you need to set the
1915 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1916 Now 4 algorithms for mcs51 jumptable generation are used:
1917 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1918 addresses loaded pc-relative for up to 112 cases and stack-pushing

1949 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1951 * added libc directory. The current version of LibC contains string
1952 functions, ctype functions and macros and some functions of the
1953 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1954 be extensively tested in the future. Standard disclaimer here.
1955 Library is not automatically build yet. But one can build it by
1956 invoking 'make' inside the libc directory.

1967 * (pic16_storeForReturn): optimized return of 0,
1968 * (genCmp): experimental code for new genCmp which uses PIC18's
1969 special compare&skip instructions. Initial tests fail some times
1970 with variables grater than 1 byte in size, so new code is disabled,
1971 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1973 * (genCast): began a fix to optimize the casting of a bit to another
1974 bit, now assigning a bitfield to another bitfield will fail, sorry,

1983 and 1 for banking instruction,
1984 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1985 caused stop processing pCodes after a inline assembly block,
1986 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1987 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1988 registers when it shouldn't,
1989 * src/pic16/ralloc.c (allocReg): add preliminary support for
1990 supporting a limited set of temporary registers,
1992 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1994 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1995 genDataPointerSet): ensure assignments always copy in MSB to LSB
1997 (loadRegFromAop): recognize CLRH optimization,
1998 (genFunction): optimize RECEIVE iCodes in reentrant functions
2000 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2002 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4999 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5000 loaded with the linker search paths (-L arguments) and the libraries
5001 to be linked with the current source (-l arguments). Changes
5002 currently will affect only the pic16 port.
5003 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5004 include path the port specific paths and port specific libraries,
5005 * gplink command now contains the $3 argument,
5006 * src/pic16/device.h,
5007 * src/pic16/device.c,: structure PIC_device is made public and

5023 Documenting changes from previous commits.
5024 * configure.in (version 1.56),
5025 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5026 when generating output files to configure the pic16 library,
5027 but now I've commented it out, since gputils aren't installed in the
5028 SF compile farm, so library won't compile
5030 * device/lib/Makefile.in (version 1.56): initially I've added in
5031 target 'all' the prerequestive 'model-pic16' so it compiled the
5032 pic16 library, but now I've commented it out for the same reasons
5034 * added targets 'model-pic16' and 'objects-pic16' to compile the
5036 * added target 'port-specific-objects-pic16' to handle the
5037 generated libraries and copy them into the build/ directory
5038 * added target 'clean-intermediate-pic16' to clean intermediate
5039 files into pic16 directory
5040 * in target 'installdirs' added line to create directory pic16 in
5041 the installation path

5044 added lines to copy all header files to installation path,
5045 * in target 'installdirs' added line create directory for pic16
5046 headers in the installation path

5062 option so that it actually works. Made it specific to the z80, since
5063 the gbz80 doesn't have these kinds of I/O ports.
5065 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5067 * device/include/z180.h,

5333 PIC16 port related changes:
5334 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5335 added variable stackPos,
5337 * gen.c: genCall, assignResultValue: added support for
5338 pushing/retrieving function parameters to/from stack,
5339 genFunction,genEndFunction: setup stack frame for the
5341 genAddrOf: will be changed according to bug 863624
5343 * added files genutils.c and genutils.h which contain gen*
5344 debugged and optimised functions extracted from gen.c
5346 * glue.c: added variable 'externs' which holds extern symbols,
5347 pic16emitRegularMap: is modified to properly handle relocatable
5348 symbols under the new scheme,
5349 pic16createInterruptVect: is modified
5350 pic16printPublics: is modified to emit 'global' assembler directives,
5351 added pic16_printExterns to print extern symbols,
5352 pic16glue: initializes stack/frame pointer in the beginning of
5353 the assembly output. Temporary hack, will be corrected later,
5354 because gplink yet does not support stack and SDCC does not
5355 yet support a type of crt0.o object to create the final binary.
5357 * Removed many lines that contain 8051 legacy code.
5358 * The code is finally placed under a 'code' directive.
5359 * Added port specific options.
5361 * _process_pragma: simplified since now we do not need *special*
5362 include file to define SFR registers. But a separate header
5363 will be needed. This will be developed later.
5364 * _pic16_parseOptions: added, parses port specific options:
5365 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5366 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5367 --preplace-udata-with=
5369 * _pic16_setDefaultOptions: modified to initialize section names,
5370 but hack is temporarly out of order since it needs improvement.
5371 * _pic16_genAssemblerPreamble: configuration words are emitted by
5372 their address instead of their name. This part is incomplete and
5373 supports only the 18Fxx2 devices. Other devices will emit an error
5374 during assembly since they do not contain the same set of config
5376 * _pic16_genIVT: is modified,
5378 * pcode.c: added definitions for some hardware registers that are needed
5380 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5381 All PCI entries are updated. Now LFSR is supported.
5382 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5383 * added pic16_newpCodeOpLit2 to support instructions with
5384 two literal arguments
5385 * pic16_pCode2str: corrected code that emits assembler instructions
5386 with two literal operands and those that have an access bit modifier
5387 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5388 this fixes a bug which caused some labels to be lost, when an
5389 assembler directive was added, i.e. banksel,
5390 * pic16_FixRegisterBanking: improved logic that causes the insertion
5392 * InlineFunction: functions that are called once, are not any more
5393 inlined. This can be a port option in the future,
5395 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5397 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5398 hold the corresponding uninitialized symbols,
5399 * pic16_allocProcessorRegister: registers have explicit marked the
5401 * pic16_allocInternalRegister: registers are explicit marked as
5403 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5404 processing list, so bit registers were lost,
5407 * ralloc.h: added field 'accessBank' and original symbol operand
5408 in register definition,
5409 * removed the field isMapped from register definition,
5411 ** Several functions have been removed from various sources:
5412 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5413 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5414 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5415 pic16_assignRelocatableRegisters
5417 ** others have been introduced:
5418 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5419 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5421 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5423 * support/scripts/inc2h.pl: changed definition of BIT_AT
5424 to emit 'sbit at' instead of 'bit at'. This was a request.
5426 PIC16 port related preliminary changes:
5427 * gen.c: prefixed function popRegFromString with
5428 pic16_ and all references to it corrected
5429 * pcode.c: all pic16_pc_* hardware registers prefixed
5430 with underscore (_),
5431 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5432 * ralloc.c: newReg(): when register is REG_SFR then
5433 set address to rIdx,
5434 pic16_allocProcessorRegister(): marks register wasUsed=0
5435 pic16_writeUsedRegs(): added a call to assign processor
5436 registers via pic16_assignFixedRegisters
5438 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5440 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5441 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5442 variables in unused register banks. Also the SSEG is placed
5443 wherever there is enough space for it, and IDATA can be anywhere
5444 in internal RAM. For now compile using -Wl-Y[stack_size].
5445 The mem file is different for this option as well, since it
5446 makes no sense of talking about DSEG lenght.
5448 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5450 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5451 in certain cases, e.g. when ROM assignment, patch provided
5452 from Albert den Haan.
5454 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5695 * src/SDCCast.c (decorateType): disabled a transformation I added in
5696 revision 1.188 (access to fields of a structure at an absolute address);
5697 it breaks with bitfields, extern declarations, and gcse analysis.
5698 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5699 could be assigned through a pointer, so don't complain.
5700 * src/SDCCast.c (astErrors),

6320 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
6321 and restore of EA so that stack offsets to parameters are
6322 correct when using both critical and reentrant/stack-auto.
6323 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
6324 size (can be triggered in error if sloc is shared between
6325 different sized objects)

6340 support for standard C idiom of memory mapped variables; for
6341 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6342 to xdata int at 0x1234 tempvar = 1.
6343 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6344 provided by Akiya ISHIDA

6360 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6362 Fixed bug #621531 (const & volatile confusion in the type chain).
6363 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6364 refer to the const or volatile state of the pointer itself.

6429 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
6430 pcoderegs.h, ralloc.c, ralloc.h
6431 * main.c: added top header and GPL license notice

6455 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6456 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6457 fetching of the pointer
6458 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6459 copied from genNearPointerSet()
6460 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6461 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6462 If they pop r0/r1 they must be called in the opposite order than aopOp().
6463 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6464 (resp. --stack-auto), prepared for --xstack

6475 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6477 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6478 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6479 type for bits was changed. It resulted in bit variables becoming
6480 global, which is not permitted in PIC 14 assembly output.
6482 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6484 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6497 A few small changes that speed up the peephole optimizer.
6501 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6503 Try to make the peephole optimizer smarter by maintaining
6504 an association between the assembly source code and the
6505 iCodes that originated them. Put this information to use
6506 with a new peephole rule condition "notVolatile" so that
6507 the rules can be aggressive yet still safe.
6512 * src/mcs51/peeph.def
6514 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6518 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6519 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6520 if the left or right operand symbols have the accuse flag set.
6522 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6524 Changed the type of the result of the ! (NOT) operator to char;
6525 previously it returned the same type as the source. This allows
6526 us to eliminate all the genFloatNot functions (all of its target
6527 implementations were very buggy) since !float can use the same
6530 * src/SDCCicode.c (ast2iCode): ! returns char

6539 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6540 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6541 during interrupts. Ensure WSAVE is located at a shared bank address.
6542 2. Fixed page selection in some places
6543 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6544 the registers name strings.
6545 4. Fixed "signed / unsigned compare" compiler warnings.
6546 5. The PIC port manages its own allocation of the general purpose
6547 registers, but makes no attempt to reuse them. As a result when
6548 compiling it soon runs out of general purpose registers. Some
6549 additional code was added to the files pcode.c and device.c to walk
6550 through the function call tree and rename the registers so that they
6560 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6561 genPlus() & genMinus() when the result is the same as left or right

6567 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6569 Made bitfield a distinct type from bit so that bitfields
6570 convert as per ANSI C and bits retain their traditional
6571 boolean style behaviour. Implemented bitfield support in
6579 * src/ds390/gen.c: bit v bitfield split
6580 * src/z80/gen.c: New support for bitfields
6581 * support/regression/tests/bitfields.c: reenabled z80,
6584 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6586 Rules 246.x, 247.x relate to bitfields, the others speed up
6587 access to xdata mapped I/O devices.
6589 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6591 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6593 Cleaned up genPackBits and genUnpackBits and added two helper
6594 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6595 for literal assignments in genPackBits (thanks to Frieder for
6601 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6603 Fixed bug #748310 (pointer to function type mishandled when the
6604 function name is omitted). Also fixed a SIGSEGV when a function
6605 attribute (reentrant, etc) is used on a non-function or on a
6606 function but misplaced before the parameter list.
6608 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6610 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6611 * support/Util/SDCCerr.h,
6612 * support/Util/SDCCerr.c: Added func attr misuse error msg

6633 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6635 Made the constant following the "interrupt" keyword optional. If
6636 omitted, the function will not automatically be given an entry
6637 in the interrupt vector table (similar to #pragma NOIV, but
6638 less syntacticly kludgy). The interrupt number is also now
6639 range checked. Also fixed a bug in the high order bit example

6653 * src/SDCCicode.c (operandOperation): rewritten some ops
6654 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6655 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6657 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6658 be re-activated by defining REDUCE_LITERALS)
6659 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6660 unsigned, but are signed by default
6661 * src/SDCCval.c (constVal): rearranged
6662 * src/SDCCval.c (valMod): preliminary fix
6663 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6705 constants are unsigned; added recognition of "u" flag for unsigned
6706 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6707 * src/SDCCval.c (valDiv, valMod): fixed signdness
6708 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6709 signedness of modulo, left and right shift

7168 * src/SDCCmain.c: linkOptions is changed to set *,
7169 added if/endif conditional macros to remove options help
7170 messages from optionsTable when a port is not configured, added
7171 support for the PIc16 port in the ports table, when executing
7172 the compiler with no port specified on command line, a default
7173 port is selected with the new macro DEFAULT_PORT which is
7174 defined in port.h, in setDefaultOptions() linkOptions is removed
7175 from initialization assignment, since now it is a set,
7176 parseCmdLine uses setParseWithComma for linkOptions, in
7177 linkEdit() linkOptions are accessed with new function indexSet()
7178 which returns the i'th item of a set variable. See SDCCset.c, in
7179 linkEdit() when calling buildCmdLine(), added linkOptions as
7180 last argument. Now users can pass arguments to gplink via the
7181 -Wl option, main() uses pic16glue() to glue up pic16 programs

7195 gpasm complaining and test the linkage with gplink, _linkCmd and
7196 _asmCmd changed to be more gplink and gpasm friendly
7197 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7198 produced an error when parsed, peep rule 12 is added to utilize
7199 movff, but it is commented out since the pCode does not support
7200 yet a command with 2 address arguments
7202 2003-05-18 <johan AT balder>
7204 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7231 2003-05-11 Borut Razem <borut.razem AT siol.net>
7233 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7234 the path of bin directory, so that PATH is the only env. variable, which has to be set
7235 in case of standard installation.

8256 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8257 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8259 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8260 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8262 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8263 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8265 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8267 * in \sdcc\as\mcs51\ changed these files in order to create an
8268 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8269 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8270 following files to include the previous two files: aslink.dsp,
8271 Makefile.aslink, Makefile.bcc, and Makefile.in.
8273 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8274 .adb instead of .cdb
8276 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8278 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8279 value from option --iram-size.
8281 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8283 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8286 2002-09-18 <wiml AT hhhh.org>
8288 * SDCClrange.h: exposed setFromRange() and setToRange()
8289 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8290 packRegsForAccUse() (bug 542397)
8291 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8292 multiple times and emitting the fetch operations more than once
8293 added aopGetUsesAcc() function to allow binary operators to
8294 fetch their operands in the correct order; made genMinus() emit
8295 compact code for X = LITERAL - Y
8297 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8298 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8299 sprintf() in line 1267.
8301 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8302 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8305 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8306 Changes to aslink (All the changes are marked with 'JCF'):
8308 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8311 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8312 area BSEG. Also moves, if possible, the DATA area down into the internal
8313 ram so more space is available.
8315 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8318 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8319 not bytes. Function summary() which creates a memory usage summary
8320 file with extension .mem. Reports of overlaping stack and small stack
8321 size. If the space for the stack is less than 16 bytes aslink trows a
8324 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8325 the 8051. Option 'y' for memory summary output file.
8327 Changes to sdcc (All the changes are marked with 'JCF'):
8329 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8331 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8332 overlaying area for it (uses RegBankUsed[4]).
8334 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8335 bank zero as used by default. By default aslink locates the stack
8336 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8337 the creation of the .mem file. Delegates the allocation of data area
8338 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8339 the begining of the stack area to aslink.
8341 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8342 glue() in SDCCglue.c creates an area for it.
8344 2002-09-03 Borut Razem <borut.razem AT siol.net>
8345 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8346 sdcc/src/pic/glue.c:
8347 introduced atexit() handler for teporay files removal in case of
8348 errors, assertions, ...
8350 2002-08-29 Borut Razem <borut.razem AT siol.net>
8351 * sdcc/support/cpp2/auto-host_vc_in.h:
8352 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8353 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8354 Maybe there is a similar problem with BORLANDC? It should be checked!
8356 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8357 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8358 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8359 was not executed, and the compiler (cl) launched a warning:
8360 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8362 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8363 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8365 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8366 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8368 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8369 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8370 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8371 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8372 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8373 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8374 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8375 - added Release configuration in VS projects
8376 - review of compiler an linker options
8377 - VC .exe files are generated in bin_vc directory, not to interfere
8378 with binaries generated from other projects (cygwin, mingw, bcc ...)
8380 * sdcc/src/yacc.dsp: added
8382 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8383 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8384 and insert the version number definitions from .version
8386 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8388 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8389 added - genarate auto-host.h using auto-host_vc_in.h as template
8392 removed from CVS, generated automatically
8394 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8395 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8397 2002-08-11 Borut Razem <borut.razem AT siol.net>
8398 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8400 2002-08-10 Borut Razem <borut.razem AT siol.net>
8401 * src/SDCCmain.c (main):
8402 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8403 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8404 The consequence was that some temporary files were not removed.
8407 unification of code in functions tempfilename() and tempfile():
8408 function tempnam() is defined in Visual Studio 6.0 and .NET
8410 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8412 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8413 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8414 - removed compiler command line option /WX: Treats all warnings as errors
8415 - update a list of source files, included into the project
8417 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8418 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8419 changed project type to Generic Project so that can be correcly converted to VS.NET project
8421 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8423 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8425 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8427 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8428 added return 0 statements after assert() to make compiler happy
8430 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8431 added newline in the def file to keep MSC compiler satisfied
8433 * sdcc/src/z80/gen.c:
8434 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8435 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8436 - solved MSC error in function aopDump()
8438 * sdcc_vc.h: define PREFIX as "\\sdcc"
8440 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8441 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8443 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8444 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8445 - Rewrote the register banking algorithm.
8446 - Added pCode live-range analysis to registers (for now, only non-used and
8447 singly-used registers optimized away)
8449 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8451 * 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.
8453 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8454 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8456 2002-04-22 Michael Hope <michaelh AT vroom>

8476 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8478 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8480 2002-03-28 Johan Knol <johan AT balder>
8482 * src/SDCCval.c: fixed bug #532436
8484 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8486 Added "char *Processor" field to the port structure.
8489 Added -p option. Allows port dependent processor to be specified.
8492 Initialized the new field char *Processor field to NULL in all ports
8495 Compiler generated registers for interrupt context saving
8496 were not getting allocated.
8498 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8501 Fixed left shift. Will promote the left side of a left shift
8502 if a) left shifting more than size of operand or b) when assigned
8503 to something size > size of left side
8505 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8507 tons of changes. Register allocation has been
8508 rewritten. Added customization for the various PICs. Flow
8509 analysis is restructured. ...
8515 Added. device.c is a PIC port hack to accomodate variations
8518 2002-03-13 Michael Hope <michaelh AT vroom>
8520 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8522 2002-03-04 johanknol <johanknol AT manik>
8524 * /src/SDCCval.c: fixed
8526 const unsigned char arr[][2] = { { 0, 1 } };

8529 2002-03-04 bela <bela AT manik>
8531 * /device/include/mcs51reg.h:
8532 ds89c420 register definition update
8534 2002-03-03 <johan AT FRIJA>

8613 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8615 * sdcc/src/SDCCloop.c:
8616 Previous fix was not good. basic blocks that have "break" or "return" are
8617 not really partof a loop , but live ranges used in these blocks should
8618 be live thru the entire loop, so set partOfLoop but don't add them to
8621 2002-02-21 <johan AT FRIJA>
8623 * src/SDCCcse.c: fixed bug #514308
8625 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8628 Fixed BUG #519583. If a conditional block ended in a return/break
8629 statement inside a loop, it was not being considered part of the loop.
8631 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8633 2002-02-10 Karl Bongers <karl AT turbobit.com>
8636 Fixed up SDCDB debugger somewhat. Updated debugger/README
8637 with lots of comments and notes.
8639 * device/examples/test2.c:
8640 Fix bug, "red" variable not being initialized(compiler complained).
8642 * device/examples/Makefile, examples/test3.c:
8643 Add Makefile in device/examples folder, compiles test3.c
8644 for use as a multiple module SDCDB test case.
8646 * sim/ucsim/cmd.src/cmdset.cc:
8647 Took out debug printfs in ucsim "next" command.
8650 Karl and Johan start ucsim XA support. Most dissassembly working,
8651 about 75% emulation done(plenty of work remaining).
8653 * sim/ucsim/z80.src:
8654 Add Z80 support to ucsim, add test-ucz80 regression test,
8655 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8656 Notice z80 compiler fails on examples/test3.c/crc code.

8689 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8690 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8691 set preprocessor defines (depending on options)
8693 * src/SDCCicode.c, src/SDCCicode.h:
8694 changes made to handle multiple sends & receives
8697 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
