1090 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1091 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1092 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1093 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1094 always available in leading double underscore form. The C99 support is
1095 mostly missing, but it's a start.
1096 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1097 reserved identifier "__data".

1175 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1177 * device/lib/printf_large.c: removed inline assembly for portability and
1178 readability. Use printf_fast if speed or size are more important.
1179 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1180 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1182 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1184 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1185 prevent compiler warning
1187 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1189 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1190 moved to level 0 and declared as static. Also they are explicit
1191 placed in access bank. This was necessery because some times they
1192 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1193 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1194 optimizations. Currently only compare to unsigned char is implemented,
1195 * src/pic16/gen.c: added fReturnIdx array,
1196 * (struct resolvedIfx) is moved to gen.h and made public,
1197 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1198 * (aopForSym): added an optimization to directly store in stack of
1199 the operand of a SEND iCode,
1200 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1201 but as registers instead (AOP_REG) using the fReturnIdx array,
1202 * (pic16_freeAsmop): remove the freed register from the
1203 _G.sregsAlloc field,
1204 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1205 a compare of 'WREG',
1206 * (pic16_popGetTempRegCond): changed function prototype, now
1207 function takes also a bitVector argument v which holds the current
1208 set of registers that are allocated for stack access by aopForSym,
1209 registers allocated in aopForSym for accessing stack symbols are not
1210 any more part of the functions usedRegs field,
1211 * (genCall): some times aopOp is called for a stack variable to be
1212 send, aopForSym might perform the push, if this is true make sure
1213 that genCall doesn't push the variable twice by testing _G.resDirect,
1214 * (genFunction): changed testing for unspecified interrupt number
1215 from 256 to INTNO_UNSPEC,
1216 * modified selection scheme of frame pointer generation. Previously
1217 if function did use local registers a frame pointer was generated,
1218 now a frame pointer is generated only if function has arguments
1219 (that need PLUSW2 register access), or has stack arguments, or the
1220 compiler is not instructed to omit the frame pointer,
1221 * (genEndFunction): before restoring local registers that were saved
1222 in the function preamble, also restore the registers that *might*
1223 have been allocated for stack access,
1224 * (genRet): removed some old comments,
1225 * (genCmp, the active (RN's) version): added a call to the
1226 pic16_genCmp_special function to perform the compare with a more
1227 robust and optimized way,
1228 * (genInline): a feature has been added in inline code generation,
1229 which allows a wildcard variable substitution when writing inline
1230 assembly. Code is incomplete and experimental therefore undocumented,
1231 * (genCast): changed order of aopOp for result and right to allow
1232 aopForSym to directly load the result if possible,
1233 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1234 perform an optimized compare on some selected special occasions,
1235 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1236 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1237 generate an IVT any more,
1238 * src/pic16/main.c (pic16_optionsTable): added command line option
1240 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1241 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1243 * src/pic16/NOTES: Raphael Neider added in list of active developers
1244 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1245 jumptable_end to prevent bug #,
1246 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1247 inCond and outCond fields,
1248 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1249 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1250 turn off register spilling,
1251 * (packRegsForOneUse): synced with other ports' versions although it
1252 is not used currently,
1253 * (pic16_packRegisters): added an optimization while reading
1254 structure bitfields, some registers may be saved (malloc code is
1255 decreased by 80 bytes)
1257 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1259 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1260 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1261 this can be optimized more?
1263 2005-03-10 Raphael Neider <rneider AT web.de>
1265 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1266 genNearPointerGet): (hopefully) fixed access to bitfields via
1267 pointers (p->bitN = x; and x = p->bitN; failed)
1269 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1312 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1313 to keep the correct label reference count when adding/removing references
1314 to labels. A peephole file using this is appended to patch #1144962.

1901 Adding support for replacing ljmps with sjmps in jumptables
1902 generated for switch statements. For now you need to set the
1903 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1904 Now 4 algorithms for mcs51 jumptable generation are used:
1905 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1906 addresses loaded pc-relative for up to 112 cases and stack-pushing
1907 target addresses loaded with offset from dptr for up to 256 cases.

1937 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1939 * added libc directory. The current version of LibC contains string
1940 functions, ctype functions and macros and some functions of the
1941 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1942 be extensively tested in the future. Standard disclaimer here.
1943 Library is not automatically build yet. But one can build it by
1944 invoking 'make' inside the libc directory.

1955 * (pic16_storeForReturn): optimized return of 0,
1956 * (genCmp): experimental code for new genCmp which uses PIC18's
1957 special compare&skip instructions. Initial tests fail some times
1958 with variables grater than 1 byte in size, so new code is disabled,
1959 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1961 * (genCast): began a fix to optimize the casting of a bit to another
1962 bit, now assigning a bitfield to another bitfield will fail, sorry,

1971 and 1 for banking instruction,
1972 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1973 caused stop processing pCodes after a inline assembly block,
1974 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1976 registers when it shouldn't,
1977 * src/pic16/ralloc.c (allocReg): add preliminary support for
1978 supporting a limited set of temporary registers,
1980 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1982 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1983 genDataPointerSet): ensure assignments always copy in MSB to LSB
1985 (loadRegFromAop): recognize CLRH optimization,
1986 (genFunction): optimize RECEIVE iCodes in reentrant functions
1988 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1990 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4899 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4901 * src/SDCCast.c: added an additional type flow in decorateType() of
4902 opposite direction, see feature request #860006; it's enabled at runtime
4903 by setting the environment variable SDCC_NEWTYPEFLOW
4904 * src/SDCCast.h: changed prototype of decorateType()

4985 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4987 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4988 loaded with the linker search paths (-L arguments) and the libraries
4989 to be linked with the current source (-l arguments). Changes
4990 currently will affect only the pic16 port.
4991 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4992 include path the port specific paths and port specific libraries,
4993 * gplink command now contains the $3 argument,
4994 * src/pic16/device.h,
4995 * src/pic16/device.c,: structure PIC_device is made public and
4996 renamed to PIC16_device, the same for variable Pics which is renamed

5011 Documenting changes from previous commits.
5012 * configure.in (version 1.56),
5013 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5014 when generating output files to configure the pic16 library,
5015 but now I've commented it out, since gputils aren't installed in the
5016 SF compile farm, so library won't compile
5018 * device/lib/Makefile.in (version 1.56): initially I've added in
5019 target 'all' the prerequestive 'model-pic16' so it compiled the
5020 pic16 library, but now I've commented it out for the same reasons
5022 * added targets 'model-pic16' and 'objects-pic16' to compile the
5024 * added target 'port-specific-objects-pic16' to handle the
5025 generated libraries and copy them into the build/ directory
5026 * added target 'clean-intermediate-pic16' to clean intermediate
5027 files into pic16 directory
5028 * in target 'installdirs' added line to create directory pic16 in

5332 debugged and optimised functions extracted from gen.c
5334 * glue.c: added variable 'externs' which holds extern symbols,
5335 pic16emitRegularMap: is modified to properly handle relocatable
5336 symbols under the new scheme,
5337 pic16createInterruptVect: is modified
5338 pic16printPublics: is modified to emit 'global' assembler directives,
5339 added pic16_printExterns to print extern symbols,
5340 pic16glue: initializes stack/frame pointer in the beginning of
5341 the assembly output. Temporary hack, will be corrected later,
5342 because gplink yet does not support stack and SDCC does not
5343 yet support a type of crt0.o object to create the final binary.
5345 * Removed many lines that contain 8051 legacy code.
5346 * The code is finally placed under a 'code' directive.
5347 * Added port specific options.
5349 * _process_pragma: simplified since now we do not need *special*
5350 include file to define SFR registers. But a separate header
5351 will be needed. This will be developed later.
5352 * _pic16_parseOptions: added, parses port specific options:
5353 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5354 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5355 --preplace-udata-with=
5357 * _pic16_setDefaultOptions: modified to initialize section names,
5358 but hack is temporarly out of order since it needs improvement.
5359 * _pic16_genAssemblerPreamble: configuration words are emitted by
5360 their address instead of their name. This part is incomplete and
5361 supports only the 18Fxx2 devices. Other devices will emit an error
5362 during assembly since they do not contain the same set of config
5364 * _pic16_genIVT: is modified,
5366 * pcode.c: added definitions for some hardware registers that are needed
5368 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5369 All PCI entries are updated. Now LFSR is supported.
5370 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5371 * added pic16_newpCodeOpLit2 to support instructions with
5372 two literal arguments
5373 * pic16_pCode2str: corrected code that emits assembler instructions
5374 with two literal operands and those that have an access bit modifier
5375 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5376 this fixes a bug which caused some labels to be lost, when an
5377 assembler directive was added, i.e. banksel,
5378 * pic16_FixRegisterBanking: improved logic that causes the insertion
5380 * InlineFunction: functions that are called once, are not any more
5381 inlined. This can be a port option in the future,
5383 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5385 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5386 hold the corresponding uninitialized symbols,
5387 * pic16_allocProcessorRegister: registers have explicit marked the
5389 * pic16_allocInternalRegister: registers are explicit marked as
5391 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5392 processing list, so bit registers were lost,
5395 * ralloc.h: added field 'accessBank' and original symbol operand
5396 in register definition,
5397 * removed the field isMapped from register definition,
5399 ** Several functions have been removed from various sources:
5400 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5401 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5402 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5403 pic16_assignRelocatableRegisters
5405 ** others have been introduced:
5406 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5407 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5409 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5411 * support/scripts/inc2h.pl: changed definition of BIT_AT
5412 to emit 'sbit at' instead of 'bit at'. This was a request.
5414 PIC16 port related preliminary changes:
5415 * gen.c: prefixed function popRegFromString with
5416 pic16_ and all references to it corrected
5417 * pcode.c: all pic16_pc_* hardware registers prefixed
5418 with underscore (_),
5419 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5420 * ralloc.c: newReg(): when register is REG_SFR then
5421 set address to rIdx,
5422 pic16_allocProcessorRegister(): marks register wasUsed=0
5423 pic16_writeUsedRegs(): added a call to assign processor
5424 registers via pic16_assignFixedRegisters
5426 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5428 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5429 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5430 variables in unused register banks. Also the SSEG is placed
5431 wherever there is enough space for it, and IDATA can be anywhere
5432 in internal RAM. For now compile using -Wl-Y[stack_size].
5433 The mem file is different for this option as well, since it
5434 makes no sense of talking about DSEG lenght.
5436 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5438 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5439 in certain cases, e.g. when ROM assignment, patch provided
5440 from Albert den Haan.
5442 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5585 * src/mcs51/peephole.def,
5586 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5587 (allows non-interrupt and interrupt code to safely compete for a resource

5598 multiply defined with mismatching "at" address.
5600 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5681 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5683 * src/SDCCast.c (decorateType): disabled a transformation I added in
5684 revision 1.188 (access to fields of a structure at an absolute address);
5685 it breaks with bitfields, extern declarations, and gcse analysis.
5686 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5687 could be assigned through a pointer, so don't complain.
5688 * src/SDCCast.c (astErrors),
5690 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5790 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5792 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
5793 uninitialized variables) for the mcs51. Set environment variable

6444 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6445 fetching of the pointer
6446 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6447 copied from genNearPointerSet()
6448 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6449 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6465 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6466 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6467 type for bits was changed. It resulted in bit variables becoming
6468 global, which is not permitted in PIC 14 assembly output.
6470 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6472 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6485 A few small changes that speed up the peephole optimizer.
6489 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6491 Try to make the peephole optimizer smarter by maintaining
6492 an association between the assembly source code and the
6493 iCodes that originated them. Put this information to use
6494 with a new peephole rule condition "notVolatile" so that
6495 the rules can be aggressive yet still safe.
6500 * src/mcs51/peeph.def
6502 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6506 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6507 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6508 if the left or right operand symbols have the accuse flag set.
6510 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 Changed the type of the result of the ! (NOT) operator to char;
6513 previously it returned the same type as the source. This allows
6514 us to eliminate all the genFloatNot functions (all of its target
6515 implementations were very buggy) since !float can use the same
6518 * src/SDCCicode.c (ast2iCode): ! returns char

6527 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6528 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6529 during interrupts. Ensure WSAVE is located at a shared bank address.
6530 2. Fixed page selection in some places
6531 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6532 the registers name strings.
6533 4. Fixed "signed / unsigned compare" compiler warnings.
6534 5. The PIC port manages its own allocation of the general purpose
6535 registers, but makes no attempt to reuse them. As a result when
6536 compiling it soon runs out of general purpose registers. Some
6537 additional code was added to the files pcode.c and device.c to walk
6538 through the function call tree and rename the registers so that they
6548 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6549 genPlus() & genMinus() when the result is the same as left or right

6555 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6557 Made bitfield a distinct type from bit so that bitfields
6558 convert as per ANSI C and bits retain their traditional
6559 boolean style behaviour. Implemented bitfield support in
6567 * src/ds390/gen.c: bit v bitfield split
6568 * src/z80/gen.c: New support for bitfields
6569 * support/regression/tests/bitfields.c: reenabled z80,
6572 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6574 Rules 246.x, 247.x relate to bitfields, the others speed up
6575 access to xdata mapped I/O devices.
6577 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6579 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6581 Cleaned up genPackBits and genUnpackBits and added two helper
6582 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6583 for literal assignments in genPackBits (thanks to Frieder for
6589 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6591 Fixed bug #748310 (pointer to function type mishandled when the
6592 function name is omitted). Also fixed a SIGSEGV when a function
6593 attribute (reentrant, etc) is used on a non-function or on a
6594 function but misplaced before the parameter list.
6596 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6598 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6599 * support/Util/SDCCerr.h,
6600 * support/Util/SDCCerr.c: Added func attr misuse error msg

6621 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6623 Made the constant following the "interrupt" keyword optional. If
6624 omitted, the function will not automatically be given an entry
6625 in the interrupt vector table (similar to #pragma NOIV, but
6626 less syntacticly kludgy). The interrupt number is also now
6627 range checked. Also fixed a bug in the high order bit example

6638 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6640 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
6641 * src/SDCCicode.c (operandOperation): rewritten some ops
6642 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6643 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6645 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6646 be re-activated by defining REDUCE_LITERALS)
6647 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6648 unsigned, but are signed by default
6649 * src/SDCCval.c (constVal): rearranged
6650 * src/SDCCval.c (valMod): preliminary fix
6651 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6693 constants are unsigned; added recognition of "u" flag for unsigned
6694 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6695 * src/SDCCval.c (valDiv, valMod): fixed signdness
6696 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6697 signedness of modulo, left and right shift

7156 * src/SDCCmain.c: linkOptions is changed to set *,
7157 added if/endif conditional macros to remove options help
7158 messages from optionsTable when a port is not configured, added
7159 support for the PIc16 port in the ports table, when executing
7160 the compiler with no port specified on command line, a default
7161 port is selected with the new macro DEFAULT_PORT which is
7162 defined in port.h, in setDefaultOptions() linkOptions is removed
7163 from initialization assignment, since now it is a set,
7164 parseCmdLine uses setParseWithComma for linkOptions, in
7165 linkEdit() linkOptions are accessed with new function indexSet()
7166 which returns the i'th item of a set variable. See SDCCset.c, in
7167 linkEdit() when calling buildCmdLine(), added linkOptions as
7168 last argument. Now users can pass arguments to gplink via the
7169 -Wl option, main() uses pic16glue() to glue up pic16 programs

7181 * src/pic16/glue.c: commented out some error producing lines
7182 * src/pic16/main.c: __config directives are commented out to stop
7183 gpasm complaining and test the linkage with gplink, _linkCmd and
7184 _asmCmd changed to be more gplink and gpasm friendly
7185 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7186 produced an error when parsed, peep rule 12 is added to utilize
7187 movff, but it is commented out since the pCode does not support
7188 yet a command with 2 address arguments
7190 2003-05-18 <johan AT balder>
7192 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7217 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7219 2003-05-11 Borut Razem <borut.razem AT siol.net>
7221 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7222 the path of bin directory, so that PATH is the only env. variable, which has to be set
7223 in case of standard installation.
7224 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8251 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8253 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8255 * in \sdcc\as\mcs51\ changed these files in order to create an
8256 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8257 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8258 following files to include the previous two files: aslink.dsp,
8259 Makefile.aslink, Makefile.bcc, and Makefile.in.
8261 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8262 .adb instead of .cdb
8264 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8266 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8267 value from option --iram-size.
8269 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8271 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8274 2002-09-18 <wiml AT hhhh.org>
8276 * SDCClrange.h: exposed setFromRange() and setToRange()
8277 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8278 packRegsForAccUse() (bug 542397)
8279 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8280 multiple times and emitting the fetch operations more than once
8281 added aopGetUsesAcc() function to allow binary operators to
8282 fetch their operands in the correct order; made genMinus() emit
8283 compact code for X = LITERAL - Y
8285 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8286 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8287 sprintf() in line 1267.
8289 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8290 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8293 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8294 Changes to aslink (All the changes are marked with 'JCF'):
8296 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8299 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8300 area BSEG. Also moves, if possible, the DATA area down into the internal
8301 ram so more space is available.
8303 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8306 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8307 not bytes. Function summary() which creates a memory usage summary
8308 file with extension .mem. Reports of overlaping stack and small stack
8309 size. If the space for the stack is less than 16 bytes aslink trows a
8312 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8313 the 8051. Option 'y' for memory summary output file.
8315 Changes to sdcc (All the changes are marked with 'JCF'):
8317 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8319 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8320 overlaying area for it (uses RegBankUsed[4]).
8322 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8323 bank zero as used by default. By default aslink locates the stack
8324 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8325 the creation of the .mem file. Delegates the allocation of data area
8326 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8327 the begining of the stack area to aslink.
8329 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8330 glue() in SDCCglue.c creates an area for it.
8332 2002-09-03 Borut Razem <borut.razem AT siol.net>
8333 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8334 sdcc/src/pic/glue.c:
8335 introduced atexit() handler for teporay files removal in case of
8336 errors, assertions, ...
8338 2002-08-29 Borut Razem <borut.razem AT siol.net>
8339 * sdcc/support/cpp2/auto-host_vc_in.h:
8340 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8341 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8342 Maybe there is a similar problem with BORLANDC? It should be checked!
8344 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8345 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8346 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8347 was not executed, and the compiler (cl) launched a warning:
8348 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8350 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8351 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8353 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8354 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8356 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8357 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8358 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8359 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8360 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8361 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8362 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8363 - added Release configuration in VS projects
8364 - review of compiler an linker options
8365 - VC .exe files are generated in bin_vc directory, not to interfere
8366 with binaries generated from other projects (cygwin, mingw, bcc ...)
8368 * sdcc/src/yacc.dsp: added
8370 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8371 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8372 and insert the version number definitions from .version
8374 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8376 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8377 added - genarate auto-host.h using auto-host_vc_in.h as template
8380 removed from CVS, generated automatically
8382 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8383 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8385 2002-08-11 Borut Razem <borut.razem AT siol.net>
8386 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8388 2002-08-10 Borut Razem <borut.razem AT siol.net>
8389 * src/SDCCmain.c (main):
8390 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8391 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8392 The consequence was that some temporary files were not removed.
8395 unification of code in functions tempfilename() and tempfile():
8396 function tempnam() is defined in Visual Studio 6.0 and .NET
8398 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8400 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8401 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8402 - removed compiler command line option /WX: Treats all warnings as errors
8403 - update a list of source files, included into the project
8405 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8406 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8407 changed project type to Generic Project so that can be correcly converted to VS.NET project
8409 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8411 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8413 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8415 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8416 added return 0 statements after assert() to make compiler happy
8418 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8419 added newline in the def file to keep MSC compiler satisfied
8421 * sdcc/src/z80/gen.c:
8422 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8423 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8424 - solved MSC error in function aopDump()
8426 * sdcc_vc.h: define PREFIX as "\\sdcc"
8428 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8429 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8431 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8432 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8433 - Rewrote the register banking algorithm.
8434 - Added pCode live-range analysis to registers (for now, only non-used and
8435 singly-used registers optimized away)
8437 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8439 * 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.
8441 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8442 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8444 2002-04-22 Michael Hope <michaelh AT vroom>

8466 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8468 2002-03-28 Johan Knol <johan AT balder>
8470 * src/SDCCval.c: fixed bug #532436
8472 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8474 Added "char *Processor" field to the port structure.
8477 Added -p option. Allows port dependent processor to be specified.
8480 Initialized the new field char *Processor field to NULL in all ports
8483 Compiler generated registers for interrupt context saving
8484 were not getting allocated.
8486 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8489 Fixed left shift. Will promote the left side of a left shift
8490 if a) left shifting more than size of operand or b) when assigned
8491 to something size > size of left side
8493 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8495 tons of changes. Register allocation has been
8496 rewritten. Added customization for the various PICs. Flow
8497 analysis is restructured. ...
8503 Added. device.c is a PIC port hack to accomodate variations
8506 2002-03-13 Michael Hope <michaelh AT vroom>
8508 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8601 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8603 * sdcc/src/SDCCloop.c:
8604 Previous fix was not good. basic blocks that have "break" or "return" are
8605 not really partof a loop , but live ranges used in these blocks should
8606 be live thru the entire loop, so set partOfLoop but don't add them to
8609 2002-02-21 <johan AT FRIJA>
8611 * src/SDCCcse.c: fixed bug #514308
8613 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8616 Fixed BUG #519583. If a conditional block ended in a return/break
8617 statement inside a loop, it was not being considered part of the loop.
8619 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8621 2002-02-10 Karl Bongers <karl AT turbobit.com>
8624 Fixed up SDCDB debugger somewhat. Updated debugger/README
8625 with lots of comments and notes.
8627 * device/examples/test2.c:
8628 Fix bug, "red" variable not being initialized(compiler complained).
8630 * device/examples/Makefile, examples/test3.c:
8631 Add Makefile in device/examples folder, compiles test3.c
8632 for use as a multiple module SDCDB test case.
8634 * sim/ucsim/cmd.src/cmdset.cc:
8635 Took out debug printfs in ucsim "next" command.
8638 Karl and Johan start ucsim XA support. Most dissassembly working,
8639 about 75% emulation done(plenty of work remaining).
8641 * sim/ucsim/z80.src:
8642 Add Z80 support to ucsim, add test-ucz80 regression test,
8643 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
8644 Notice z80 compiler fails on examples/test3.c/crc code.

8677 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
8678 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
8679 set preprocessor defines (depending on options)
8681 * src/SDCCicode.c, src/SDCCicode.h:
8682 changes made to handle multiple sends & receives
8685 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
