1111 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1112 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1113 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1114 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1115 always available in leading double underscore form. The C99 support is
1116 mostly missing, but it's a start.
1117 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1118 reserved identifier "__data".

1196 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1198 * device/lib/printf_large.c: removed inline assembly for portability and
1199 readability. Use printf_fast if speed or size are more important.
1200 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1201 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1203 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1205 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1206 prevent compiler warning
1208 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1210 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1211 moved to level 0 and declared as static. Also they are explicit
1212 placed in access bank. This was necessery because some times they
1213 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1214 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1215 optimizations. Currently only compare to unsigned char is implemented,
1216 * src/pic16/gen.c: added fReturnIdx array,
1217 * (struct resolvedIfx) is moved to gen.h and made public,
1218 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1219 * (aopForSym): added an optimization to directly store in stack of
1220 the operand of a SEND iCode,
1221 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1222 but as registers instead (AOP_REG) using the fReturnIdx array,
1223 * (pic16_freeAsmop): remove the freed register from the
1224 _G.sregsAlloc field,
1225 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1226 a compare of 'WREG',
1227 * (pic16_popGetTempRegCond): changed function prototype, now
1228 function takes also a bitVector argument v which holds the current
1229 set of registers that are allocated for stack access by aopForSym,
1230 registers allocated in aopForSym for accessing stack symbols are not
1231 any more part of the functions usedRegs field,
1232 * (genCall): some times aopOp is called for a stack variable to be
1233 send, aopForSym might perform the push, if this is true make sure
1234 that genCall doesn't push the variable twice by testing _G.resDirect,
1235 * (genFunction): changed testing for unspecified interrupt number
1236 from 256 to INTNO_UNSPEC,
1237 * modified selection scheme of frame pointer generation. Previously
1238 if function did use local registers a frame pointer was generated,
1239 now a frame pointer is generated only if function has arguments
1240 (that need PLUSW2 register access), or has stack arguments, or the
1241 compiler is not instructed to omit the frame pointer,
1242 * (genEndFunction): before restoring local registers that were saved
1243 in the function preamble, also restore the registers that *might*
1244 have been allocated for stack access,
1245 * (genRet): removed some old comments,
1246 * (genCmp, the active (RN's) version): added a call to the
1247 pic16_genCmp_special function to perform the compare with a more
1248 robust and optimized way,
1249 * (genInline): a feature has been added in inline code generation,
1250 which allows a wildcard variable substitution when writing inline
1251 assembly. Code is incomplete and experimental therefore undocumented,
1252 * (genCast): changed order of aopOp for result and right to allow
1253 aopForSym to directly load the result if possible,
1254 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1255 perform an optimized compare on some selected special occasions,
1256 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1257 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1258 generate an IVT any more,
1259 * src/pic16/main.c (pic16_optionsTable): added command line option
1261 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1262 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1264 * src/pic16/NOTES: Raphael Neider added in list of active developers
1265 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1266 jumptable_end to prevent bug #,
1267 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1268 inCond and outCond fields,
1269 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1270 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1271 turn off register spilling,
1272 * (packRegsForOneUse): synced with other ports' versions although it
1273 is not used currently,
1274 * (pic16_packRegisters): added an optimization while reading
1275 structure bitfields, some registers may be saved (malloc code is
1276 decreased by 80 bytes)
1278 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1280 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1281 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1282 this can be optimized more?
1284 2005-03-10 Raphael Neider <rneider AT web.de>
1286 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1287 genNearPointerGet): (hopefully) fixed access to bitfields via
1288 pointers (p->bitN = x; and x = p->bitN; failed)
1290 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1292 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1922 Adding support for replacing ljmps with sjmps in jumptables
1923 generated for switch statements. For now you need to set the
1924 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1925 Now 4 algorithms for mcs51 jumptable generation are used:
1926 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1927 addresses loaded pc-relative for up to 112 cases and stack-pushing

1958 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1960 * added libc directory. The current version of LibC contains string
1961 functions, ctype functions and macros and some functions of the
1962 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1963 be extensively tested in the future. Standard disclaimer here.
1964 Library is not automatically build yet. But one can build it by
1965 invoking 'make' inside the libc directory.

1976 * (pic16_storeForReturn): optimized return of 0,
1977 * (genCmp): experimental code for new genCmp which uses PIC18's
1978 special compare&skip instructions. Initial tests fail some times
1979 with variables grater than 1 byte in size, so new code is disabled,
1980 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1982 * (genCast): began a fix to optimize the casting of a bit to another
1983 bit, now assigning a bitfield to another bitfield will fail, sorry,

1992 and 1 for banking instruction,
1993 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1994 caused stop processing pCodes after a inline assembly block,
1995 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1996 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1997 registers when it shouldn't,
1998 * src/pic16/ralloc.c (allocReg): add preliminary support for
1999 supporting a limited set of temporary registers,
2001 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2003 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2007 (genFunction): optimize RECEIVE iCodes in reentrant functions
2009 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5009 loaded with the linker search paths (-L arguments) and the libraries
5010 to be linked with the current source (-l arguments). Changes
5011 currently will affect only the pic16 port.
5012 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5013 include path the port specific paths and port specific libraries,
5014 * gplink command now contains the $3 argument,
5015 * src/pic16/device.h,
5016 * src/pic16/device.c,: structure PIC_device is made public and

5032 Documenting changes from previous commits.
5033 * configure.in (version 1.56),
5034 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5035 when generating output files to configure the pic16 library,
5036 but now I've commented it out, since gputils aren't installed in the
5037 SF compile farm, so library won't compile
5039 * device/lib/Makefile.in (version 1.56): initially I've added in
5040 target 'all' the prerequestive 'model-pic16' so it compiled the
5041 pic16 library, but now I've commented it out for the same reasons
5043 * added targets 'model-pic16' and 'objects-pic16' to compile the
5045 * added target 'port-specific-objects-pic16' to handle the
5046 generated libraries and copy them into the build/ directory
5047 * added target 'clean-intermediate-pic16' to clean intermediate
5048 files into pic16 directory
5049 * in target 'installdirs' added line to create directory pic16 in
5050 the installation path

5053 added lines to copy all header files to installation path,
5054 * in target 'installdirs' added line create directory for pic16
5055 headers in the installation path

5337 * src/ds390/gen.c (genRightShift): fixed bug #870788
5338 * src/SDCCast.c (decorateType): fixed bug #870781
5340 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5342 PIC16 port related changes:
5343 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5344 added variable stackPos,
5346 * gen.c: genCall, assignResultValue: added support for
5347 pushing/retrieving function parameters to/from stack,
5348 genFunction,genEndFunction: setup stack frame for the
5350 genAddrOf: will be changed according to bug 863624
5352 * added files genutils.c and genutils.h which contain gen*
5353 debugged and optimised functions extracted from gen.c
5355 * glue.c: added variable 'externs' which holds extern symbols,
5356 pic16emitRegularMap: is modified to properly handle relocatable
5357 symbols under the new scheme,
5358 pic16createInterruptVect: is modified
5359 pic16printPublics: is modified to emit 'global' assembler directives,
5360 added pic16_printExterns to print extern symbols,
5361 pic16glue: initializes stack/frame pointer in the beginning of
5362 the assembly output. Temporary hack, will be corrected later,
5363 because gplink yet does not support stack and SDCC does not
5364 yet support a type of crt0.o object to create the final binary.
5366 * Removed many lines that contain 8051 legacy code.
5367 * The code is finally placed under a 'code' directive.
5368 * Added port specific options.
5370 * _process_pragma: simplified since now we do not need *special*
5371 include file to define SFR registers. But a separate header
5372 will be needed. This will be developed later.
5373 * _pic16_parseOptions: added, parses port specific options:
5374 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5375 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5376 --preplace-udata-with=
5378 * _pic16_setDefaultOptions: modified to initialize section names,
5379 but hack is temporarly out of order since it needs improvement.
5380 * _pic16_genAssemblerPreamble: configuration words are emitted by
5381 their address instead of their name. This part is incomplete and
5382 supports only the 18Fxx2 devices. Other devices will emit an error
5383 during assembly since they do not contain the same set of config
5385 * _pic16_genIVT: is modified,
5387 * pcode.c: added definitions for some hardware registers that are needed
5389 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5390 All PCI entries are updated. Now LFSR is supported.
5391 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5392 * added pic16_newpCodeOpLit2 to support instructions with
5393 two literal arguments
5394 * pic16_pCode2str: corrected code that emits assembler instructions
5395 with two literal operands and those that have an access bit modifier
5396 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5397 this fixes a bug which caused some labels to be lost, when an
5398 assembler directive was added, i.e. banksel,
5399 * pic16_FixRegisterBanking: improved logic that causes the insertion
5401 * InlineFunction: functions that are called once, are not any more
5402 inlined. This can be a port option in the future,
5404 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5406 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5407 hold the corresponding uninitialized symbols,
5408 * pic16_allocProcessorRegister: registers have explicit marked the
5410 * pic16_allocInternalRegister: registers are explicit marked as
5412 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5413 processing list, so bit registers were lost,
5416 * ralloc.h: added field 'accessBank' and original symbol operand
5417 in register definition,
5418 * removed the field isMapped from register definition,
5420 ** Several functions have been removed from various sources:
5421 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5422 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5423 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5424 pic16_assignRelocatableRegisters
5426 ** others have been introduced:
5427 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5428 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5430 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5432 * support/scripts/inc2h.pl: changed definition of BIT_AT
5433 to emit 'sbit at' instead of 'bit at'. This was a request.
5435 PIC16 port related preliminary changes:
5436 * gen.c: prefixed function popRegFromString with
5437 pic16_ and all references to it corrected
5438 * pcode.c: all pic16_pc_* hardware registers prefixed
5439 with underscore (_),
5440 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5441 * ralloc.c: newReg(): when register is REG_SFR then
5442 set address to rIdx,
5443 pic16_allocProcessorRegister(): marks register wasUsed=0
5444 pic16_writeUsedRegs(): added a call to assign processor
5445 registers via pic16_assignFixedRegisters
5447 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5449 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5450 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5451 variables in unused register banks. Also the SSEG is placed
5452 wherever there is enough space for it, and IDATA can be anywhere
5453 in internal RAM. For now compile using -Wl-Y[stack_size].
5454 The mem file is different for this option as well, since it
5455 makes no sense of talking about DSEG lenght.
5457 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5459 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5460 in certain cases, e.g. when ROM assignment, patch provided
5461 from Albert den Haan.
5463 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5702 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5704 * src/SDCCast.c (decorateType): disabled a transformation I added in
5705 revision 1.188 (access to fields of a structure at an absolute address);
5706 it breaks with bitfields, extern declarations, and gcse analysis.
5707 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5708 could be assigned through a pointer, so don't complain.
5709 * src/SDCCast.c (astErrors),
5711 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6349 support for standard C idiom of memory mapped variables; for
6350 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6351 to xdata int at 0x1234 tempvar = 1.
6352 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6353 provided by Akiya ISHIDA

6369 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6371 Fixed bug #621531 (const & volatile confusion in the type chain).
6372 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6373 refer to the const or volatile state of the pointer itself.

6465 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6466 fetching of the pointer
6467 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6468 copied from genNearPointerSet()
6469 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6470 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6486 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6487 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6488 type for bits was changed. It resulted in bit variables becoming
6489 global, which is not permitted in PIC 14 assembly output.
6491 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6493 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6506 A few small changes that speed up the peephole optimizer.
6510 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 Try to make the peephole optimizer smarter by maintaining
6513 an association between the assembly source code and the
6514 iCodes that originated them. Put this information to use
6515 with a new peephole rule condition "notVolatile" so that
6516 the rules can be aggressive yet still safe.
6521 * src/mcs51/peeph.def
6523 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6527 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6528 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6529 if the left or right operand symbols have the accuse flag set.
6531 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6533 Changed the type of the result of the ! (NOT) operator to char;
6534 previously it returned the same type as the source. This allows
6535 us to eliminate all the genFloatNot functions (all of its target
6536 implementations were very buggy) since !float can use the same

6549 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6550 during interrupts. Ensure WSAVE is located at a shared bank address.
6551 2. Fixed page selection in some places
6552 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6553 the registers name strings.
6554 4. Fixed "signed / unsigned compare" compiler warnings.
6555 5. The PIC port manages its own allocation of the general purpose
6556 registers, but makes no attempt to reuse them. As a result when
6557 compiling it soon runs out of general purpose registers. Some
6558 additional code was added to the files pcode.c and device.c to walk
6559 through the function call tree and rename the registers so that they
6569 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6576 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6578 Made bitfield a distinct type from bit so that bitfields
6579 convert as per ANSI C and bits retain their traditional
6580 boolean style behaviour. Implemented bitfield support in
6588 * src/ds390/gen.c: bit v bitfield split
6589 * src/z80/gen.c: New support for bitfields
6590 * support/regression/tests/bitfields.c: reenabled z80,
6593 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6595 Rules 246.x, 247.x relate to bitfields, the others speed up
6596 access to xdata mapped I/O devices.
6598 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6600 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6602 Cleaned up genPackBits and genUnpackBits and added two helper
6603 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6604 for literal assignments in genPackBits (thanks to Frieder for
6610 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6612 Fixed bug #748310 (pointer to function type mishandled when the
6613 function name is omitted). Also fixed a SIGSEGV when a function
6614 attribute (reentrant, etc) is used on a non-function or on a
6615 function but misplaced before the parameter list.
6617 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6619 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6620 * support/Util/SDCCerr.h,

6642 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6644 Made the constant following the "interrupt" keyword optional. If
6645 omitted, the function will not automatically be given an entry
6646 in the interrupt vector table (similar to #pragma NOIV, but
6647 less syntacticly kludgy). The interrupt number is also now
6648 range checked. Also fixed a bug in the high order bit example

6662 * src/SDCCicode.c (operandOperation): rewritten some ops
6663 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6664 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6666 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6667 be re-activated by defining REDUCE_LITERALS)
6668 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6669 unsigned, but are signed by default
6670 * src/SDCCval.c (constVal): rearranged
6671 * src/SDCCval.c (valMod): preliminary fix
6672 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7177 * src/SDCCmain.c: linkOptions is changed to set *,
7178 added if/endif conditional macros to remove options help
7179 messages from optionsTable when a port is not configured, added
7180 support for the PIc16 port in the ports table, when executing
7181 the compiler with no port specified on command line, a default
7182 port is selected with the new macro DEFAULT_PORT which is
7183 defined in port.h, in setDefaultOptions() linkOptions is removed
7184 from initialization assignment, since now it is a set,
7185 parseCmdLine uses setParseWithComma for linkOptions, in
7186 linkEdit() linkOptions are accessed with new function indexSet()
7187 which returns the i'th item of a set variable. See SDCCset.c, in
7188 linkEdit() when calling buildCmdLine(), added linkOptions as
7189 last argument. Now users can pass arguments to gplink via the
7190 -Wl option, main() uses pic16glue() to glue up pic16 programs

7203 * src/pic16/main.c: __config directives are commented out to stop
7204 gpasm complaining and test the linkage with gplink, _linkCmd and
7205 _asmCmd changed to be more gplink and gpasm friendly
7206 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7207 produced an error when parsed, peep rule 12 is added to utilize
7208 movff, but it is commented out since the pCode does not support
7209 yet a command with 2 address arguments
7211 2003-05-18 <johan AT balder>
7213 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7240 2003-05-11 Borut Razem <borut.razem AT siol.net>
7242 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7243 the path of bin directory, so that PATH is the only env. variable, which has to be set
7244 in case of standard installation.

8259 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8261 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8262 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8263 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8265 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8266 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8268 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8269 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8271 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8272 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8274 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8276 * in \sdcc\as\mcs51\ changed these files in order to create an
8277 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8278 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8279 following files to include the previous two files: aslink.dsp,
8280 Makefile.aslink, Makefile.bcc, and Makefile.in.
8282 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8283 .adb instead of .cdb
8285 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8287 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8288 value from option --iram-size.
8290 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8292 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8295 2002-09-18 <wiml AT hhhh.org>
8297 * SDCClrange.h: exposed setFromRange() and setToRange()
8298 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8299 packRegsForAccUse() (bug 542397)
8300 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8301 multiple times and emitting the fetch operations more than once
8302 added aopGetUsesAcc() function to allow binary operators to
8303 fetch their operands in the correct order; made genMinus() emit
8304 compact code for X = LITERAL - Y
8306 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8307 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8308 sprintf() in line 1267.
8310 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8311 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8314 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8315 Changes to aslink (All the changes are marked with 'JCF'):
8317 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8320 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8321 area BSEG. Also moves, if possible, the DATA area down into the internal
8322 ram so more space is available.
8324 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8327 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8328 not bytes. Function summary() which creates a memory usage summary
8329 file with extension .mem. Reports of overlaping stack and small stack
8330 size. If the space for the stack is less than 16 bytes aslink trows a
8333 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8334 the 8051. Option 'y' for memory summary output file.
8336 Changes to sdcc (All the changes are marked with 'JCF'):
8338 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8340 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8341 overlaying area for it (uses RegBankUsed[4]).
8343 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8344 bank zero as used by default. By default aslink locates the stack
8345 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8346 the creation of the .mem file. Delegates the allocation of data area
8347 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8348 the begining of the stack area to aslink.
8350 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8351 glue() in SDCCglue.c creates an area for it.
8353 2002-09-03 Borut Razem <borut.razem AT siol.net>
8354 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8355 sdcc/src/pic/glue.c:
8356 introduced atexit() handler for teporay files removal in case of
8357 errors, assertions, ...
8359 2002-08-29 Borut Razem <borut.razem AT siol.net>
8360 * sdcc/support/cpp2/auto-host_vc_in.h:
8361 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8362 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8363 Maybe there is a similar problem with BORLANDC? It should be checked!
8365 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8366 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8367 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8368 was not executed, and the compiler (cl) launched a warning:
8369 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8371 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8372 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8374 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8375 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8377 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8378 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8379 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8380 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8381 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8382 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8383 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8384 - added Release configuration in VS projects
8385 - review of compiler an linker options
8386 - VC .exe files are generated in bin_vc directory, not to interfere
8387 with binaries generated from other projects (cygwin, mingw, bcc ...)
8389 * sdcc/src/yacc.dsp: added
8391 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8392 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8393 and insert the version number definitions from .version
8395 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8397 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8398 added - genarate auto-host.h using auto-host_vc_in.h as template
8401 removed from CVS, generated automatically
8403 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8404 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8406 2002-08-11 Borut Razem <borut.razem AT siol.net>
8407 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8409 2002-08-10 Borut Razem <borut.razem AT siol.net>
8410 * src/SDCCmain.c (main):
8411 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8412 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8413 The consequence was that some temporary files were not removed.
8416 unification of code in functions tempfilename() and tempfile():
8417 function tempnam() is defined in Visual Studio 6.0 and .NET
8419 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8421 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8422 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8423 - removed compiler command line option /WX: Treats all warnings as errors
8424 - update a list of source files, included into the project
8426 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8427 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8428 changed project type to Generic Project so that can be correcly converted to VS.NET project
8430 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8432 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8434 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8436 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8437 added return 0 statements after assert() to make compiler happy
8439 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8440 added newline in the def file to keep MSC compiler satisfied
8442 * sdcc/src/z80/gen.c:
8443 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8444 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8445 - solved MSC error in function aopDump()
8447 * sdcc_vc.h: define PREFIX as "\\sdcc"
8449 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8450 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8452 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8453 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8454 - Rewrote the register banking algorithm.
8455 - Added pCode live-range analysis to registers (for now, only non-used and
8456 singly-used registers optimized away)
8458 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8460 * 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.

8487 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8489 2002-03-28 Johan Knol <johan AT balder>
8491 * src/SDCCval.c: fixed bug #532436
8493 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8495 Added "char *Processor" field to the port structure.
8498 Added -p option. Allows port dependent processor to be specified.
8501 Initialized the new field char *Processor field to NULL in all ports
8504 Compiler generated registers for interrupt context saving
8505 were not getting allocated.
8507 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8510 Fixed left shift. Will promote the left side of a left shift
8511 if a) left shifting more than size of operand or b) when assigned
8512 to something size > size of left side
8514 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8516 tons of changes. Register allocation has been
8517 rewritten. Added customization for the various PICs. Flow
8518 analysis is restructured. ...
8524 Added. device.c is a PIC port hack to accomodate variations
8527 2002-03-13 Michael Hope <michaelh AT vroom>
8529 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8538 2002-03-04 bela <bela AT manik>
8540 * /device/include/mcs51reg.h:
8541 ds89c420 register definition update

8622 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8624 * sdcc/src/SDCCloop.c:
8625 Previous fix was not good. basic blocks that have "break" or "return" are
8626 not really partof a loop , but live ranges used in these blocks should
8627 be live thru the entire loop, so set partOfLoop but don't add them to
8630 2002-02-21 <johan AT FRIJA>
8632 * src/SDCCcse.c: fixed bug #514308
8634 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8637 Fixed BUG #519583. If a conditional block ended in a return/break
8638 statement inside a loop, it was not being considered part of the loop.
8640 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8642 2002-02-10 Karl Bongers <karl AT turbobit.com>
8645 Fixed up SDCDB debugger somewhat. Updated debugger/README
8646 with lots of comments and notes.
8648 * device/examples/test2.c:
8649 Fix bug, "red" variable not being initialized(compiler complained).
8651 * device/examples/Makefile, examples/test3.c:
8652 Add Makefile in device/examples folder, compiles test3.c
8653 for use as a multiple module SDCDB test case.
8655 * sim/ucsim/cmd.src/cmdset.cc:
8656 Took out debug printfs in ucsim "next" command.
8659 Karl and Johan start ucsim XA support. Most dissassembly working,
8660 about 75% emulation done(plenty of work remaining).
8662 * sim/ucsim/z80.src:
8663 Add Z80 support to ucsim, add test-ucz80 regression test,
8664 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

8700 set preprocessor defines (depending on options)
8702 * src/SDCCicode.c, src/SDCCicode.h:
8703 changes made to handle multiple sends & receives
8706 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
