1214 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1216 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1218 * device/lib/printf_large.c: removed inline assembly for portability and
1219 readability. Use printf_fast if speed or size are more important.
1220 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1221 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1223 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1225 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1226 prevent compiler warning
1228 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1230 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1231 moved to level 0 and declared as static. Also they are explicit
1232 placed in access bank. This was necessery because some times they
1233 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1234 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1235 optimizations. Currently only compare to unsigned char is implemented,
1236 * src/pic16/gen.c: added fReturnIdx array,
1237 * (struct resolvedIfx) is moved to gen.h and made public,
1238 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1239 * (aopForSym): added an optimization to directly store in stack of
1240 the operand of a SEND iCode,
1241 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1242 but as registers instead (AOP_REG) using the fReturnIdx array,
1243 * (pic16_freeAsmop): remove the freed register from the
1244 _G.sregsAlloc field,
1245 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1246 a compare of 'WREG',
1247 * (pic16_popGetTempRegCond): changed function prototype, now
1248 function takes also a bitVector argument v which holds the current
1249 set of registers that are allocated for stack access by aopForSym,
1250 registers allocated in aopForSym for accessing stack symbols are not
1251 any more part of the functions usedRegs field,
1252 * (genCall): some times aopOp is called for a stack variable to be
1253 send, aopForSym might perform the push, if this is true make sure
1254 that genCall doesn't push the variable twice by testing _G.resDirect,
1255 * (genFunction): changed testing for unspecified interrupt number
1256 from 256 to INTNO_UNSPEC,
1257 * modified selection scheme of frame pointer generation. Previously
1258 if function did use local registers a frame pointer was generated,
1259 now a frame pointer is generated only if function has arguments
1260 (that need PLUSW2 register access), or has stack arguments, or the
1261 compiler is not instructed to omit the frame pointer,
1262 * (genEndFunction): before restoring local registers that were saved
1263 in the function preamble, also restore the registers that *might*
1264 have been allocated for stack access,
1265 * (genRet): removed some old comments,
1266 * (genCmp, the active (RN's) version): added a call to the
1267 pic16_genCmp_special function to perform the compare with a more
1268 robust and optimized way,
1269 * (genInline): a feature has been added in inline code generation,
1270 which allows a wildcard variable substitution when writing inline
1271 assembly. Code is incomplete and experimental therefore undocumented,
1272 * (genCast): changed order of aopOp for result and right to allow
1273 aopForSym to directly load the result if possible,
1274 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1275 perform an optimized compare on some selected special occasions,
1276 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1277 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1278 generate an IVT any more,
1279 * src/pic16/main.c (pic16_optionsTable): added command line option
1281 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1282 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1284 * src/pic16/NOTES: Raphael Neider added in list of active developers
1285 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1286 jumptable_end to prevent bug #,
1287 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1288 inCond and outCond fields,
1289 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1290 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1291 turn off register spilling,
1292 * (packRegsForOneUse): synced with other ports' versions although it
1293 is not used currently,
1294 * (pic16_packRegisters): added an optimization while reading
1295 structure bitfields, some registers may be saved (malloc code is
1296 decreased by 80 bytes)
1298 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1300 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1301 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1302 this can be optimized more?
1304 2005-03-10 Raphael Neider <rneider AT web.de>
1306 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1307 genNearPointerGet): (hopefully) fixed access to bitfields via
1308 pointers (p->bitN = x; and x = p->bitN; failed)
1310 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1312 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
1314 2005-03-09 Raphael Neider <rneider AT web.de>

1942 Adding support for replacing ljmps with sjmps in jumptables
1943 generated for switch statements. For now you need to set the
1944 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1945 Now 4 algorithms for mcs51 jumptable generation are used:
1946 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1947 addresses loaded pc-relative for up to 112 cases and stack-pushing

1980 * added libc directory. The current version of LibC contains string
1981 functions, ctype functions and macros and some functions of the
1982 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1983 be extensively tested in the future. Standard disclaimer here.

1996 * (pic16_storeForReturn): optimized return of 0,
1997 * (genCmp): experimental code for new genCmp which uses PIC18's
1998 special compare&skip instructions. Initial tests fail some times
1999 with variables grater than 1 byte in size, so new code is disabled,
2000 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2002 * (genCast): began a fix to optimize the casting of a bit to another
2003 bit, now assigning a bitfield to another bitfield will fail, sorry,

2017 registers when it shouldn't,
2018 * src/pic16/ralloc.c (allocReg): add preliminary support for
2019 supporting a limited set of temporary registers,

5029 loaded with the linker search paths (-L arguments) and the libraries
5030 to be linked with the current source (-l arguments). Changes
5031 currently will affect only the pic16 port.
5032 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5033 include path the port specific paths and port specific libraries,
5034 * gplink command now contains the $3 argument,
5035 * src/pic16/device.h,

5052 Documenting changes from previous commits.
5053 * configure.in (version 1.56),
5054 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5055 when generating output files to configure the pic16 library,
5056 but now I've commented it out, since gputils aren't installed in the
5057 SF compile farm, so library won't compile
5059 * device/lib/Makefile.in (version 1.56): initially I've added in
5060 target 'all' the prerequestive 'model-pic16' so it compiled the
5061 pic16 library, but now I've commented it out for the same reasons
5063 * added targets 'model-pic16' and 'objects-pic16' to compile the
5065 * added target 'port-specific-objects-pic16' to handle the
5066 generated libraries and copy them into the build/ directory
5067 * added target 'clean-intermediate-pic16' to clean intermediate
5068 files into pic16 directory
5069 * in target 'installdirs' added line to create directory pic16 in

5073 added lines to copy all header files to installation path,
5074 * in target 'installdirs' added line create directory for pic16
5075 headers in the installation path

5323 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5325 A python script to validate compiler diagnostic messages. It can be
5326 used to verify that sdcc complains about bad c source code and
5327 gives a good location of the error.
5328 * support/valdiag/Makefile,
5329 * support/valdiag/valdiag.py,
5330 * support/valdiag/tests/*
5332 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5334 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5335 * src/SDCCsymt.c (newEnumType),
5337 * support/Util/SDCCerr.c,
5338 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
5340 * support/regression/tests/enum.c: added test for enum values that
5341 require at least 2 bytes of storage.
5343 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5345 * src/common.h: added ifndef/define/endif macros
5346 around the header file.
5347 Bug reported from Jesus Calvino-Fraga
5349 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5351 * sdcc.spec: updated
5352 * device/include/Makefile.in: don't install CVS directories
5353 * device/lib/Makefile.in: added removal of CVS directories after install
5354 * doc/Makefile: fixed install, added local_icons
5355 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5356 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5357 * src/ds390/gen.c (genRightShift): fixed bug #870788
5358 * src/SDCCast.c (decorateType): fixed bug #870781
5360 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5362 PIC16 port related changes:
5363 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5364 added variable stackPos,
5366 * gen.c: genCall, assignResultValue: added support for
5367 pushing/retrieving function parameters to/from stack,
5368 genFunction,genEndFunction: setup stack frame for the
5370 genAddrOf: will be changed according to bug 863624
5372 * added files genutils.c and genutils.h which contain gen*
5373 debugged and optimised functions extracted from gen.c
5375 * glue.c: added variable 'externs' which holds extern symbols,
5376 pic16emitRegularMap: is modified to properly handle relocatable
5377 symbols under the new scheme,
5378 pic16createInterruptVect: is modified
5379 pic16printPublics: is modified to emit 'global' assembler directives,
5380 added pic16_printExterns to print extern symbols,
5381 pic16glue: initializes stack/frame pointer in the beginning of
5382 the assembly output. Temporary hack, will be corrected later,
5383 because gplink yet does not support stack and SDCC does not
5384 yet support a type of crt0.o object to create the final binary.
5386 * Removed many lines that contain 8051 legacy code.
5387 * The code is finally placed under a 'code' directive.
5388 * Added port specific options.
5390 * _process_pragma: simplified since now we do not need *special*
5391 include file to define SFR registers. But a separate header
5392 will be needed. This will be developed later.
5393 * _pic16_parseOptions: added, parses port specific options:
5394 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5395 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5396 --preplace-udata-with=
5398 * _pic16_setDefaultOptions: modified to initialize section names,
5399 but hack is temporarly out of order since it needs improvement.
5400 * _pic16_genAssemblerPreamble: configuration words are emitted by
5401 their address instead of their name. This part is incomplete and
5402 supports only the 18Fxx2 devices. Other devices will emit an error
5403 during assembly since they do not contain the same set of config
5405 * _pic16_genIVT: is modified,
5407 * pcode.c: added definitions for some hardware registers that are needed
5409 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5410 All PCI entries are updated. Now LFSR is supported.
5411 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5412 * added pic16_newpCodeOpLit2 to support instructions with
5413 two literal arguments
5414 * pic16_pCode2str: corrected code that emits assembler instructions
5415 with two literal operands and those that have an access bit modifier
5416 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5417 this fixes a bug which caused some labels to be lost, when an
5418 assembler directive was added, i.e. banksel,
5419 * pic16_FixRegisterBanking: improved logic that causes the insertion
5421 * InlineFunction: functions that are called once, are not any more
5422 inlined. This can be a port option in the future,
5424 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5426 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5427 hold the corresponding uninitialized symbols,
5428 * pic16_allocProcessorRegister: registers have explicit marked the
5430 * pic16_allocInternalRegister: registers are explicit marked as
5432 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5433 processing list, so bit registers were lost,
5436 * ralloc.h: added field 'accessBank' and original symbol operand
5437 in register definition,
5438 * removed the field isMapped from register definition,
5440 ** Several functions have been removed from various sources:
5441 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5442 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5443 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5444 pic16_assignRelocatableRegisters
5446 ** others have been introduced:
5447 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5448 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5450 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5452 * support/scripts/inc2h.pl: changed definition of BIT_AT
5453 to emit 'sbit at' instead of 'bit at'. This was a request.
5455 PIC16 port related preliminary changes:
5456 * gen.c: prefixed function popRegFromString with
5457 pic16_ and all references to it corrected
5458 * pcode.c: all pic16_pc_* hardware registers prefixed
5459 with underscore (_),
5460 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5461 * ralloc.c: newReg(): when register is REG_SFR then
5462 set address to rIdx,
5463 pic16_allocProcessorRegister(): marks register wasUsed=0
5464 pic16_writeUsedRegs(): added a call to assign processor
5465 registers via pic16_assignFixedRegisters
5467 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5469 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5470 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5471 variables in unused register banks. Also the SSEG is placed
5472 wherever there is enough space for it, and IDATA can be anywhere
5473 in internal RAM. For now compile using -Wl-Y[stack_size].
5474 The mem file is different for this option as well, since it
5475 makes no sense of talking about DSEG lenght.
5477 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5479 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5480 in certain cases, e.g. when ROM assignment, patch provided
5481 from Albert den Haan.
5483 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5626 * src/mcs51/peephole.def,
5627 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5628 (allows non-interrupt and interrupt code to safely compete for a resource

5722 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5724 * src/SDCCast.c (decorateType): disabled a transformation I added in
5725 revision 1.188 (access to fields of a structure at an absolute address);
5726 it breaks with bitfields, extern declarations, and gcse analysis.
5727 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5728 could be assigned through a pointer, so don't complain.
5729 * src/SDCCast.c (astErrors),
5731 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6369 support for standard C idiom of memory mapped variables; for
6370 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6371 to xdata int at 0x1234 tempvar = 1.
6372 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6373 provided by Akiya ISHIDA

6389 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6391 Fixed bug #621531 (const & volatile confusion in the type chain).
6392 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
6393 refer to the const or volatile state of the pointer itself.

6484 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6485 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6486 fetching of the pointer
6487 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6488 copied from genNearPointerSet()
6489 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6490 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6506 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6507 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6508 type for bits was changed. It resulted in bit variables becoming
6509 global, which is not permitted in PIC 14 assembly output.
6511 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6513 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6526 A few small changes that speed up the peephole optimizer.
6530 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6532 Try to make the peephole optimizer smarter by maintaining
6533 an association between the assembly source code and the
6534 iCodes that originated them. Put this information to use
6535 with a new peephole rule condition "notVolatile" so that
6536 the rules can be aggressive yet still safe.
6541 * src/mcs51/peeph.def
6543 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6547 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6548 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6549 if the left or right operand symbols have the accuse flag set.
6551 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6553 Changed the type of the result of the ! (NOT) operator to char;
6554 previously it returned the same type as the source. This allows
6555 us to eliminate all the genFloatNot functions (all of its target
6556 implementations were very buggy) since !float can use the same

6568 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6569 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6570 during interrupts. Ensure WSAVE is located at a shared bank address.
6571 2. Fixed page selection in some places
6572 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6573 the registers name strings.
6574 4. Fixed "signed / unsigned compare" compiler warnings.
6575 5. The PIC port manages its own allocation of the general purpose
6576 registers, but makes no attempt to reuse them. As a result when
6577 compiling it soon runs out of general purpose registers. Some
6578 additional code was added to the files pcode.c and device.c to walk
6579 through the function call tree and rename the registers so that they
6589 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6590 genPlus() & genMinus() when the result is the same as left or right

6596 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6598 Made bitfield a distinct type from bit so that bitfields
6599 convert as per ANSI C and bits retain their traditional
6600 boolean style behaviour. Implemented bitfield support in
6608 * src/ds390/gen.c: bit v bitfield split
6609 * src/z80/gen.c: New support for bitfields
6610 * support/regression/tests/bitfields.c: reenabled z80,
6613 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6615 Rules 246.x, 247.x relate to bitfields, the others speed up
6616 access to xdata mapped I/O devices.
6618 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6620 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6622 Cleaned up genPackBits and genUnpackBits and added two helper
6623 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6624 for literal assignments in genPackBits (thanks to Frieder for
6630 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6632 Fixed bug #748310 (pointer to function type mishandled when the
6633 function name is omitted). Also fixed a SIGSEGV when a function
6634 attribute (reentrant, etc) is used on a non-function or on a
6635 function but misplaced before the parameter list.
6637 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6639 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6640 * support/Util/SDCCerr.h,
6641 * support/Util/SDCCerr.c: Added func attr misuse error msg

6662 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6664 Made the constant following the "interrupt" keyword optional. If
6665 omitted, the function will not automatically be given an entry
6666 in the interrupt vector table (similar to #pragma NOIV, but
6667 less syntacticly kludgy). The interrupt number is also now
6668 range checked. Also fixed a bug in the high order bit example

6682 * src/SDCCicode.c (operandOperation): rewritten some ops
6683 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6684 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6686 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6687 be re-activated by defining REDUCE_LITERALS)
6688 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6689 unsigned, but are signed by default
6690 * src/SDCCval.c (constVal): rearranged
6691 * src/SDCCval.c (valMod): preliminary fix
6692 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7198 added if/endif conditional macros to remove options help
7199 messages from optionsTable when a port is not configured, added
7200 support for the PIc16 port in the ports table, when executing
7201 the compiler with no port specified on command line, a default
7202 port is selected with the new macro DEFAULT_PORT which is
7203 defined in port.h, in setDefaultOptions() linkOptions is removed
7204 from initialization assignment, since now it is a set,
7205 parseCmdLine uses setParseWithComma for linkOptions, in
7206 linkEdit() linkOptions are accessed with new function indexSet()
7207 which returns the i'th item of a set variable. See SDCCset.c, in
7208 linkEdit() when calling buildCmdLine(), added linkOptions as
7209 last argument. Now users can pass arguments to gplink via the
7210 -Wl option, main() uses pic16glue() to glue up pic16 programs

7224 gpasm complaining and test the linkage with gplink, _linkCmd and
7225 _asmCmd changed to be more gplink and gpasm friendly
7226 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7227 produced an error when parsed, peep rule 12 is added to utilize
7228 movff, but it is commented out since the pCode does not support
7229 yet a command with 2 address arguments
7231 2003-05-18 <johan AT balder>
7233 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7260 2003-05-11 Borut Razem <borut.razem AT siol.net>
7262 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8253 * src/SDCCast.c (decorateType): fixed bug #600035
8255 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8256 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
8257 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
8258 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

8260 * src/pic/ralloc.c: outcommented unused variable to remove warnings
8262 2003-01-06 <karl AT turbobit.com>
8263 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
8266 2003-01-06 <johan AT balder>
8268 * src/SDCCicode.c: fixed array add
8270 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8271 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8272 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8274 2003-01-04 <johan AT balder>
8276 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8278 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8279 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8281 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8282 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
8283 * support/regression/tests/bug-524697.c: fit mem usage into 8032
8285 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8286 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
8288 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8289 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8291 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8292 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8294 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8296 * in \sdcc\as\mcs51\ changed these files in order to create an
8297 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8298 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8299 following files to include the previous two files: aslink.dsp,
8300 Makefile.aslink, Makefile.bcc, and Makefile.in.
8302 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8303 .adb instead of .cdb
8305 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8307 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8308 value from option --iram-size.
8310 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8312 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8315 2002-09-18 <wiml AT hhhh.org>
8317 * SDCClrange.h: exposed setFromRange() and setToRange()
8318 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8319 packRegsForAccUse() (bug 542397)
8320 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8321 multiple times and emitting the fetch operations more than once
8322 added aopGetUsesAcc() function to allow binary operators to
8323 fetch their operands in the correct order; made genMinus() emit
8324 compact code for X = LITERAL - Y
8326 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8327 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8328 sprintf() in line 1267.
8330 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8331 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8334 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8335 Changes to aslink (All the changes are marked with 'JCF'):
8337 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8340 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8341 area BSEG. Also moves, if possible, the DATA area down into the internal
8342 ram so more space is available.
8344 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8347 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8348 not bytes. Function summary() which creates a memory usage summary
8349 file with extension .mem. Reports of overlaping stack and small stack
8350 size. If the space for the stack is less than 16 bytes aslink trows a
8353 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8354 the 8051. Option 'y' for memory summary output file.
8356 Changes to sdcc (All the changes are marked with 'JCF'):
8358 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8360 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8361 overlaying area for it (uses RegBankUsed[4]).
8363 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8364 bank zero as used by default. By default aslink locates the stack
8365 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8366 the creation of the .mem file. Delegates the allocation of data area
8367 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8368 the begining of the stack area to aslink.
8370 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8371 glue() in SDCCglue.c creates an area for it.
8373 2002-09-03 Borut Razem <borut.razem AT siol.net>
8374 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8375 sdcc/src/pic/glue.c:
8376 introduced atexit() handler for teporay files removal in case of
8377 errors, assertions, ...
8379 2002-08-29 Borut Razem <borut.razem AT siol.net>
8380 * sdcc/support/cpp2/auto-host_vc_in.h:
8381 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8382 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8383 Maybe there is a similar problem with BORLANDC? It should be checked!
8385 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8386 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8387 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8388 was not executed, and the compiler (cl) launched a warning:
8389 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8391 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8392 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8394 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8395 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8397 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8398 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8399 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8400 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8401 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8402 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8403 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8404 - added Release configuration in VS projects
8405 - review of compiler an linker options
8406 - VC .exe files are generated in bin_vc directory, not to interfere
8407 with binaries generated from other projects (cygwin, mingw, bcc ...)
8409 * sdcc/src/yacc.dsp: added
8411 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8412 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8413 and insert the version number definitions from .version
8415 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8417 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8418 added - genarate auto-host.h using auto-host_vc_in.h as template
8421 removed from CVS, generated automatically
8423 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8424 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8426 2002-08-11 Borut Razem <borut.razem AT siol.net>
8427 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8429 2002-08-10 Borut Razem <borut.razem AT siol.net>
8430 * src/SDCCmain.c (main):
8431 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8432 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8433 The consequence was that some temporary files were not removed.
8436 unification of code in functions tempfilename() and tempfile():
8437 function tempnam() is defined in Visual Studio 6.0 and .NET
8439 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8441 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8442 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8443 - removed compiler command line option /WX: Treats all warnings as errors
8444 - update a list of source files, included into the project
8446 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8447 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8448 changed project type to Generic Project so that can be correcly converted to VS.NET project
8450 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8452 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8454 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8456 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8457 added return 0 statements after assert() to make compiler happy
8459 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8460 added newline in the def file to keep MSC compiler satisfied
8462 * sdcc/src/z80/gen.c:
8463 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8464 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8465 - solved MSC error in function aopDump()
8467 * sdcc_vc.h: define PREFIX as "\\sdcc"
8469 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8470 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8472 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8473 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8474 - Rewrote the register banking algorithm.
8475 - Added pCode live-range analysis to registers (for now, only non-used and
8476 singly-used registers optimized away)
8478 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8480 * 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/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8507 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8509 2002-03-28 Johan Knol <johan AT balder>
8511 * src/SDCCval.c: fixed bug #532436
8513 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8515 Added "char *Processor" field to the port structure.
8518 Added -p option. Allows port dependent processor to be specified.
8521 Initialized the new field char *Processor field to NULL in all ports
8524 Compiler generated registers for interrupt context saving
8525 were not getting allocated.
8527 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8530 Fixed left shift. Will promote the left side of a left shift
8531 if a) left shifting more than size of operand or b) when assigned
8532 to something size > size of left side
8534 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8536 tons of changes. Register allocation has been
8537 rewritten. Added customization for the various PICs. Flow
8538 analysis is restructured. ...
8544 Added. device.c is a PIC port hack to accomodate variations
8547 2002-03-13 Michael Hope <michaelh AT vroom>
8549 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8551 2002-03-04 johanknol <johanknol AT manik>
8553 * /src/SDCCval.c: fixed
8555 const unsigned char arr[][2] = { { 0, 1 } };
8556 t18.c:1: error: Initializer element is not constant
8558 2002-03-04 bela <bela AT manik>
8560 * /device/include/mcs51reg.h:
8561 ds89c420 register definition update
8563 2002-03-03 <johan AT FRIJA>

8642 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8644 * sdcc/src/SDCCloop.c:
8645 Previous fix was not good. basic blocks that have "break" or "return" are
8646 not really partof a loop , but live ranges used in these blocks should
8647 be live thru the entire loop, so set partOfLoop but don't add them to
8650 2002-02-21 <johan AT FRIJA>
8652 * src/SDCCcse.c: fixed bug #514308
8654 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8657 Fixed BUG #519583. If a conditional block ended in a return/break
8658 statement inside a loop, it was not being considered part of the loop.
8660 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8662 2002-02-10 Karl Bongers <karl AT turbobit.com>
8665 Fixed up SDCDB debugger somewhat. Updated debugger/README
8666 with lots of comments and notes.
8668 * device/examples/test2.c:
8669 Fix bug, "red" variable not being initialized(compiler complained).
8671 * device/examples/Makefile, examples/test3.c:
8672 Add Makefile in device/examples folder, compiles test3.c
8673 for use as a multiple module SDCDB test case.
8675 * sim/ucsim/cmd.src/cmdset.cc:
8676 Took out debug printfs in ucsim "next" command.
8679 Karl and Johan start ucsim XA support. Most dissassembly working,
8680 about 75% emulation done(plenty of work remaining).
8682 * sim/ucsim/z80.src:
8683 Add Z80 support to ucsim, add test-ucz80 regression test,
8684 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8685 Notice z80 compiler fails on examples/test3.c/crc code.
8687 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

8699 3) added __builtin_swapw swap bytes of a short
8701 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
8702 1) handle multiple send & receives from register bank1
8703 2) ralloc can now allocate DPTR1 to some liveRanges
8705 * src/SDCCsymt.c, src/SDCCsymt.h:
8706 changes to handle multiple sends & receives
8709 added some pointer arithmetic optimization
8712 added some pointer arithmetic optimizations but not stable yet so not
8713 called from anywhere (will get this working shortly)
8715 * src/SDCCopt.c: fixed for multiple sends & receives
8718 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8719 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8720 set preprocessor defines (depending on options)
8722 * src/SDCCicode.c, src/SDCCicode.h:
8723 changes made to handle multiple sends & receives
8726 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
