1212 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1214 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1216 * device/lib/printf_large.c: removed inline assembly for portability and
1217 readability. Use printf_fast if speed or size are more important.
1218 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1219 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1221 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1223 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1224 prevent compiler warning
1226 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1228 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1229 moved to level 0 and declared as static. Also they are explicit
1230 placed in access bank. This was necessery because some times they
1231 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1232 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1233 optimizations. Currently only compare to unsigned char is implemented,
1234 * src/pic16/gen.c: added fReturnIdx array,
1235 * (struct resolvedIfx) is moved to gen.h and made public,
1236 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1237 * (aopForSym): added an optimization to directly store in stack of
1238 the operand of a SEND iCode,
1239 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1240 but as registers instead (AOP_REG) using the fReturnIdx array,
1241 * (pic16_freeAsmop): remove the freed register from the
1242 _G.sregsAlloc field,
1243 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1244 a compare of 'WREG',
1245 * (pic16_popGetTempRegCond): changed function prototype, now
1246 function takes also a bitVector argument v which holds the current
1247 set of registers that are allocated for stack access by aopForSym,
1248 registers allocated in aopForSym for accessing stack symbols are not
1249 any more part of the functions usedRegs field,
1250 * (genCall): some times aopOp is called for a stack variable to be
1251 send, aopForSym might perform the push, if this is true make sure
1252 that genCall doesn't push the variable twice by testing _G.resDirect,
1253 * (genFunction): changed testing for unspecified interrupt number
1254 from 256 to INTNO_UNSPEC,
1255 * modified selection scheme of frame pointer generation. Previously
1256 if function did use local registers a frame pointer was generated,
1257 now a frame pointer is generated only if function has arguments
1258 (that need PLUSW2 register access), or has stack arguments, or the
1259 compiler is not instructed to omit the frame pointer,
1260 * (genEndFunction): before restoring local registers that were saved
1261 in the function preamble, also restore the registers that *might*
1262 have been allocated for stack access,
1263 * (genRet): removed some old comments,
1264 * (genCmp, the active (RN's) version): added a call to the
1265 pic16_genCmp_special function to perform the compare with a more
1266 robust and optimized way,
1267 * (genInline): a feature has been added in inline code generation,
1268 which allows a wildcard variable substitution when writing inline
1269 assembly. Code is incomplete and experimental therefore undocumented,
1270 * (genCast): changed order of aopOp for result and right to allow
1271 aopForSym to directly load the result if possible,
1272 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1273 perform an optimized compare on some selected special occasions,
1274 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1275 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1276 generate an IVT any more,
1277 * src/pic16/main.c (pic16_optionsTable): added command line option
1279 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1280 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1282 * src/pic16/NOTES: Raphael Neider added in list of active developers
1283 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1284 jumptable_end to prevent bug #,
1285 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1286 inCond and outCond fields,
1287 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1288 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1289 turn off register spilling,
1290 * (packRegsForOneUse): synced with other ports' versions although it
1291 is not used currently,
1292 * (pic16_packRegisters): added an optimization while reading
1293 structure bitfields, some registers may be saved (malloc code is
1294 decreased by 80 bytes)
1296 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1298 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1299 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1300 this can be optimized more?
1302 2005-03-10 Raphael Neider <rneider AT web.de>
1304 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1305 genNearPointerGet): (hopefully) fixed access to bitfields via
1306 pointers (p->bitN = x; and x = p->bitN; failed)
1308 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1310 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
1312 2005-03-09 Raphael Neider <rneider AT web.de>

1941 generated for switch statements. For now you need to set the
1942 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1943 Now 4 algorithms for mcs51 jumptable generation are used:
1944 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1978 * added libc directory. The current version of LibC contains string
1979 functions, ctype functions and macros and some functions of the
1980 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1981 be extensively tested in the future. Standard disclaimer here.

1994 * (pic16_storeForReturn): optimized return of 0,
1995 * (genCmp): experimental code for new genCmp which uses PIC18's
1996 special compare&skip instructions. Initial tests fail some times
1997 with variables grater than 1 byte in size, so new code is disabled,
1998 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2000 * (genCast): began a fix to optimize the casting of a bit to another
2001 bit, now assigning a bitfield to another bitfield will fail, sorry,

2015 registers when it shouldn't,
2016 * src/pic16/ralloc.c (allocReg): add preliminary support for
2017 supporting a limited set of temporary registers,

5027 loaded with the linker search paths (-L arguments) and the libraries
5028 to be linked with the current source (-l arguments). Changes
5029 currently will affect only the pic16 port.
5030 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5031 include path the port specific paths and port specific libraries,
5032 * gplink command now contains the $3 argument,
5033 * src/pic16/device.h,
5034 * src/pic16/device.c,: structure PIC_device is made public and
5035 renamed to PIC16_device, the same for variable Pics which is renamed

5050 Documenting changes from previous commits.
5051 * configure.in (version 1.56),
5052 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5053 when generating output files to configure the pic16 library,
5054 but now I've commented it out, since gputils aren't installed in the
5055 SF compile farm, so library won't compile
5057 * device/lib/Makefile.in (version 1.56): initially I've added in
5058 target 'all' the prerequestive 'model-pic16' so it compiled the
5059 pic16 library, but now I've commented it out for the same reasons
5061 * added targets 'model-pic16' and 'objects-pic16' to compile the
5063 * added target 'port-specific-objects-pic16' to handle the
5064 generated libraries and copy them into the build/ directory
5065 * added target 'clean-intermediate-pic16' to clean intermediate
5066 files into pic16 directory
5067 * in target 'installdirs' added line to create directory pic16 in

5071 added lines to copy all header files to installation path,
5072 * in target 'installdirs' added line create directory for pic16
5073 headers in the installation path

5341 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5343 * src/common.h: added ifndef/define/endif macros
5344 around the header file.
5345 Bug reported from Jesus Calvino-Fraga
5347 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5349 * sdcc.spec: updated
5350 * device/include/Makefile.in: don't install CVS directories
5351 * device/lib/Makefile.in: added removal of CVS directories after install
5352 * doc/Makefile: fixed install, added local_icons
5353 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5354 * src/mcs51/gen.c (genRightShift): fixed bug #870788

5358 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5360 PIC16 port related changes:
5361 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5362 added variable stackPos,
5364 * gen.c: genCall, assignResultValue: added support for
5365 pushing/retrieving function parameters to/from stack,
5366 genFunction,genEndFunction: setup stack frame for the
5368 genAddrOf: will be changed according to bug 863624
5370 * added files genutils.c and genutils.h which contain gen*
5371 debugged and optimised functions extracted from gen.c
5373 * glue.c: added variable 'externs' which holds extern symbols,
5374 pic16emitRegularMap: is modified to properly handle relocatable
5375 symbols under the new scheme,
5376 pic16createInterruptVect: is modified
5377 pic16printPublics: is modified to emit 'global' assembler directives,
5378 added pic16_printExterns to print extern symbols,
5379 pic16glue: initializes stack/frame pointer in the beginning of
5380 the assembly output. Temporary hack, will be corrected later,
5381 because gplink yet does not support stack and SDCC does not
5382 yet support a type of crt0.o object to create the final binary.
5384 * Removed many lines that contain 8051 legacy code.
5385 * The code is finally placed under a 'code' directive.
5386 * Added port specific options.
5388 * _process_pragma: simplified since now we do not need *special*
5389 include file to define SFR registers. But a separate header
5390 will be needed. This will be developed later.
5391 * _pic16_parseOptions: added, parses port specific options:
5392 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5393 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5394 --preplace-udata-with=
5396 * _pic16_setDefaultOptions: modified to initialize section names,
5397 but hack is temporarly out of order since it needs improvement.
5398 * _pic16_genAssemblerPreamble: configuration words are emitted by
5399 their address instead of their name. This part is incomplete and
5400 supports only the 18Fxx2 devices. Other devices will emit an error
5401 during assembly since they do not contain the same set of config
5403 * _pic16_genIVT: is modified,
5405 * pcode.c: added definitions for some hardware registers that are needed
5407 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5408 All PCI entries are updated. Now LFSR is supported.
5409 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5410 * added pic16_newpCodeOpLit2 to support instructions with
5411 two literal arguments
5412 * pic16_pCode2str: corrected code that emits assembler instructions
5413 with two literal operands and those that have an access bit modifier
5414 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5415 this fixes a bug which caused some labels to be lost, when an
5416 assembler directive was added, i.e. banksel,
5417 * pic16_FixRegisterBanking: improved logic that causes the insertion
5419 * InlineFunction: functions that are called once, are not any more
5420 inlined. This can be a port option in the future,
5422 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5424 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5425 hold the corresponding uninitialized symbols,
5426 * pic16_allocProcessorRegister: registers have explicit marked the
5428 * pic16_allocInternalRegister: registers are explicit marked as
5430 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5431 processing list, so bit registers were lost,
5434 * ralloc.h: added field 'accessBank' and original symbol operand
5435 in register definition,
5436 * removed the field isMapped from register definition,
5438 ** Several functions have been removed from various sources:
5439 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5440 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5441 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5442 pic16_assignRelocatableRegisters
5444 ** others have been introduced:
5445 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5446 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5448 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5450 * support/scripts/inc2h.pl: changed definition of BIT_AT
5451 to emit 'sbit at' instead of 'bit at'. This was a request.
5453 PIC16 port related preliminary changes:
5454 * gen.c: prefixed function popRegFromString with
5455 pic16_ and all references to it corrected
5456 * pcode.c: all pic16_pc_* hardware registers prefixed
5457 with underscore (_),
5458 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5459 * ralloc.c: newReg(): when register is REG_SFR then
5460 set address to rIdx,
5461 pic16_allocProcessorRegister(): marks register wasUsed=0
5462 pic16_writeUsedRegs(): added a call to assign processor
5463 registers via pic16_assignFixedRegisters
5465 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5467 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5468 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5469 variables in unused register banks. Also the SSEG is placed
5470 wherever there is enough space for it, and IDATA can be anywhere
5471 in internal RAM. For now compile using -Wl-Y[stack_size].
5472 The mem file is different for this option as well, since it
5473 makes no sense of talking about DSEG lenght.
5475 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5477 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5478 in certain cases, e.g. when ROM assignment, patch provided
5479 from Albert den Haan.
5481 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5720 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5722 * src/SDCCast.c (decorateType): disabled a transformation I added in
5723 revision 1.188 (access to fields of a structure at an absolute address);
5724 it breaks with bitfields, extern declarations, and gcse analysis.
5725 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5726 could be assigned through a pointer, so don't complain.
5727 * src/SDCCast.c (astErrors),
5729 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6368 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6369 to xdata int at 0x1234 tempvar = 1.
6370 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6371 provided by Akiya ISHIDA

6483 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6484 fetching of the pointer
6485 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6486 copied from genNearPointerSet()
6487 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6488 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6504 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6505 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6506 type for bits was changed. It resulted in bit variables becoming
6507 global, which is not permitted in PIC 14 assembly output.
6509 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6511 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6524 A few small changes that speed up the peephole optimizer.
6528 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6530 Try to make the peephole optimizer smarter by maintaining
6531 an association between the assembly source code and the
6532 iCodes that originated them. Put this information to use
6533 with a new peephole rule condition "notVolatile" so that
6534 the rules can be aggressive yet still safe.
6539 * src/mcs51/peeph.def
6541 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6545 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6546 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6547 if the left or right operand symbols have the accuse flag set.
6549 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6551 Changed the type of the result of the ! (NOT) operator to char;
6552 previously it returned the same type as the source. This allows
6553 us to eliminate all the genFloatNot functions (all of its target
6554 implementations were very buggy) since !float can use the same
6557 * src/SDCCicode.c (ast2iCode): ! returns char

6566 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6567 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6568 during interrupts. Ensure WSAVE is located at a shared bank address.
6569 2. Fixed page selection in some places
6570 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6571 the registers name strings.
6572 4. Fixed "signed / unsigned compare" compiler warnings.
6573 5. The PIC port manages its own allocation of the general purpose
6574 registers, but makes no attempt to reuse them. As a result when
6575 compiling it soon runs out of general purpose registers. Some
6576 additional code was added to the files pcode.c and device.c to walk
6577 through the function call tree and rename the registers so that they
6587 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6588 genPlus() & genMinus() when the result is the same as left or right

6594 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6596 Made bitfield a distinct type from bit so that bitfields
6597 convert as per ANSI C and bits retain their traditional
6598 boolean style behaviour. Implemented bitfield support in
6606 * src/ds390/gen.c: bit v bitfield split
6607 * src/z80/gen.c: New support for bitfields
6608 * support/regression/tests/bitfields.c: reenabled z80,
6611 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6613 Rules 246.x, 247.x relate to bitfields, the others speed up
6614 access to xdata mapped I/O devices.
6616 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6618 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6620 Cleaned up genPackBits and genUnpackBits and added two helper
6621 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6622 for literal assignments in genPackBits (thanks to Frieder for
6628 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6630 Fixed bug #748310 (pointer to function type mishandled when the
6631 function name is omitted). Also fixed a SIGSEGV when a function
6632 attribute (reentrant, etc) is used on a non-function or on a
6633 function but misplaced before the parameter list.
6635 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6637 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6638 * support/Util/SDCCerr.h,
6639 * support/Util/SDCCerr.c: Added func attr misuse error msg

6660 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6662 Made the constant following the "interrupt" keyword optional. If
6663 omitted, the function will not automatically be given an entry
6664 in the interrupt vector table (similar to #pragma NOIV, but
6665 less syntacticly kludgy). The interrupt number is also now
6666 range checked. Also fixed a bug in the high order bit example

6680 * src/SDCCicode.c (operandOperation): rewritten some ops
6681 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6682 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6684 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6685 be re-activated by defining REDUCE_LITERALS)
6686 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6687 unsigned, but are signed by default
6688 * src/SDCCval.c (constVal): rearranged
6689 * src/SDCCval.c (valMod): preliminary fix
6690 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6732 constants are unsigned; added recognition of "u" flag for unsigned
6733 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6734 * src/SDCCval.c (valDiv, valMod): fixed signdness
6735 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6736 signedness of modulo, left and right shift

7196 added if/endif conditional macros to remove options help
7197 messages from optionsTable when a port is not configured, added
7198 support for the PIc16 port in the ports table, when executing
7199 the compiler with no port specified on command line, a default
7200 port is selected with the new macro DEFAULT_PORT which is
7201 defined in port.h, in setDefaultOptions() linkOptions is removed
7202 from initialization assignment, since now it is a set,
7203 parseCmdLine uses setParseWithComma for linkOptions, in
7204 linkEdit() linkOptions are accessed with new function indexSet()
7205 which returns the i'th item of a set variable. See SDCCset.c, in
7206 linkEdit() when calling buildCmdLine(), added linkOptions as
7207 last argument. Now users can pass arguments to gplink via the
7208 -Wl option, main() uses pic16glue() to glue up pic16 programs

7222 gpasm complaining and test the linkage with gplink, _linkCmd and
7223 _asmCmd changed to be more gplink and gpasm friendly
7224 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7225 produced an error when parsed, peep rule 12 is added to utilize
7226 movff, but it is commented out since the pCode does not support
7227 yet a command with 2 address arguments
7229 2003-05-18 <johan AT balder>
7231 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7258 2003-05-11 Borut Razem <borut.razem AT siol.net>
7260 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8260 2003-01-06 <karl AT turbobit.com>
8261 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
8264 2003-01-06 <johan AT balder>
8266 * src/SDCCicode.c: fixed array add
8268 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8269 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8270 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8272 2003-01-04 <johan AT balder>
8274 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8276 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8277 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8279 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8280 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8281 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8283 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8284 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8286 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8287 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8289 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8290 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8292 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8294 * in \sdcc\as\mcs51\ changed these files in order to create an
8295 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8296 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8297 following files to include the previous two files: aslink.dsp,
8298 Makefile.aslink, Makefile.bcc, and Makefile.in.
8300 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8301 .adb instead of .cdb
8303 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8305 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8306 value from option --iram-size.
8308 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8310 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8313 2002-09-18 <wiml AT hhhh.org>
8315 * SDCClrange.h: exposed setFromRange() and setToRange()
8316 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8317 packRegsForAccUse() (bug 542397)
8318 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8319 multiple times and emitting the fetch operations more than once
8320 added aopGetUsesAcc() function to allow binary operators to
8321 fetch their operands in the correct order; made genMinus() emit
8322 compact code for X = LITERAL - Y
8324 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8325 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8326 sprintf() in line 1267.
8328 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8329 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8332 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8333 Changes to aslink (All the changes are marked with 'JCF'):
8335 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8338 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8339 area BSEG. Also moves, if possible, the DATA area down into the internal
8340 ram so more space is available.
8342 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8345 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8346 not bytes. Function summary() which creates a memory usage summary
8347 file with extension .mem. Reports of overlaping stack and small stack
8348 size. If the space for the stack is less than 16 bytes aslink trows a
8351 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8352 the 8051. Option 'y' for memory summary output file.
8354 Changes to sdcc (All the changes are marked with 'JCF'):
8356 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8358 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8359 overlaying area for it (uses RegBankUsed[4]).
8361 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8362 bank zero as used by default. By default aslink locates the stack
8363 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8364 the creation of the .mem file. Delegates the allocation of data area
8365 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8366 the begining of the stack area to aslink.
8368 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8369 glue() in SDCCglue.c creates an area for it.
8371 2002-09-03 Borut Razem <borut.razem AT siol.net>
8372 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8373 sdcc/src/pic/glue.c:
8374 introduced atexit() handler for teporay files removal in case of
8375 errors, assertions, ...
8377 2002-08-29 Borut Razem <borut.razem AT siol.net>
8378 * sdcc/support/cpp2/auto-host_vc_in.h:
8379 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8380 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8381 Maybe there is a similar problem with BORLANDC? It should be checked!
8383 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8384 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8385 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8386 was not executed, and the compiler (cl) launched a warning:
8387 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8389 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8390 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8392 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8393 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8395 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8396 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8397 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8398 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8399 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8400 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8401 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8402 - added Release configuration in VS projects
8403 - review of compiler an linker options
8404 - VC .exe files are generated in bin_vc directory, not to interfere
8405 with binaries generated from other projects (cygwin, mingw, bcc ...)
8407 * sdcc/src/yacc.dsp: added
8409 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8410 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8411 and insert the version number definitions from .version
8413 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8415 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8416 added - genarate auto-host.h using auto-host_vc_in.h as template
8419 removed from CVS, generated automatically
8421 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8422 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8424 2002-08-11 Borut Razem <borut.razem AT siol.net>
8425 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8427 2002-08-10 Borut Razem <borut.razem AT siol.net>
8428 * src/SDCCmain.c (main):
8429 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8430 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8431 The consequence was that some temporary files were not removed.
8434 unification of code in functions tempfilename() and tempfile():
8435 function tempnam() is defined in Visual Studio 6.0 and .NET
8437 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8439 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8440 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8441 - removed compiler command line option /WX: Treats all warnings as errors
8442 - update a list of source files, included into the project
8444 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8445 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8446 changed project type to Generic Project so that can be correcly converted to VS.NET project
8448 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8450 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8452 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8454 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8455 added return 0 statements after assert() to make compiler happy
8457 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8458 added newline in the def file to keep MSC compiler satisfied
8460 * sdcc/src/z80/gen.c:
8461 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8462 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8463 - solved MSC error in function aopDump()
8465 * sdcc_vc.h: define PREFIX as "\\sdcc"
8467 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8468 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8471 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8472 - Rewrote the register banking algorithm.
8473 - Added pCode live-range analysis to registers (for now, only non-used and
8474 singly-used registers optimized away)
8476 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8478 * 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.

8505 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8507 2002-03-28 Johan Knol <johan AT balder>
8509 * src/SDCCval.c: fixed bug #532436
8511 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8513 Added "char *Processor" field to the port structure.
8516 Added -p option. Allows port dependent processor to be specified.
8519 Initialized the new field char *Processor field to NULL in all ports
8522 Compiler generated registers for interrupt context saving
8523 were not getting allocated.
8525 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8528 Fixed left shift. Will promote the left side of a left shift
8529 if a) left shifting more than size of operand or b) when assigned
8530 to something size > size of left side
8532 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8534 tons of changes. Register allocation has been
8535 rewritten. Added customization for the various PICs. Flow
8536 analysis is restructured. ...
8542 Added. device.c is a PIC port hack to accomodate variations
8545 2002-03-13 Michael Hope <michaelh AT vroom>
8547 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8556 2002-03-04 bela <bela AT manik>
8558 * /device/include/mcs51reg.h:
8559 ds89c420 register definition update
8561 2002-03-03 <johan AT FRIJA>

8640 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8642 * sdcc/src/SDCCloop.c:
8643 Previous fix was not good. basic blocks that have "break" or "return" are
8644 not really partof a loop , but live ranges used in these blocks should
8645 be live thru the entire loop, so set partOfLoop but don't add them to
8648 2002-02-21 <johan AT FRIJA>
8650 * src/SDCCcse.c: fixed bug #514308
8652 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8655 Fixed BUG #519583. If a conditional block ended in a return/break
8656 statement inside a loop, it was not being considered part of the loop.
8658 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8660 2002-02-10 Karl Bongers <karl AT turbobit.com>
8663 Fixed up SDCDB debugger somewhat. Updated debugger/README
8664 with lots of comments and notes.
8666 * device/examples/test2.c:
8667 Fix bug, "red" variable not being initialized(compiler complained).
8669 * device/examples/Makefile, examples/test3.c:
8670 Add Makefile in device/examples folder, compiles test3.c
8671 for use as a multiple module SDCDB test case.
8673 * sim/ucsim/cmd.src/cmdset.cc:
8674 Took out debug printfs in ucsim "next" command.
8677 Karl and Johan start ucsim XA support. Most dissassembly working,
8678 about 75% emulation done(plenty of work remaining).
8680 * sim/ucsim/z80.src:
8681 Add Z80 support to ucsim, add test-ucz80 regression test,
8682 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8683 Notice z80 compiler fails on examples/test3.c/crc code.

8701 2) ralloc can now allocate DPTR1 to some liveRanges
8703 * src/SDCCsymt.c, src/SDCCsymt.h:
8704 changes to handle multiple sends & receives
8707 added some pointer arithmetic optimization
8710 added some pointer arithmetic optimizations but not stable yet so not
8711 called from anywhere (will get this working shortly)
8713 * src/SDCCopt.c: fixed for multiple sends & receives
8716 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8717 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8718 set preprocessor defines (depending on options)
8720 * src/SDCCicode.c, src/SDCCicode.h:
8721 changes made to handle multiple sends & receives
8724 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
