1070 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1071 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,

1154 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1156 * device/lib/printf_large.c: removed inline assembly for portability and
1157 readability. Use printf_fast if speed or size are more important.
1158 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1159 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1161 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1163 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1164 prevent compiler warning
1166 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1168 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1169 moved to level 0 and declared as static. Also they are explicit
1170 placed in access bank. This was necessery because some times they
1171 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1172 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1173 optimizations. Currently only compare to unsigned char is implemented,
1174 * src/pic16/gen.c: added fReturnIdx array,
1175 * (struct resolvedIfx) is moved to gen.h and made public,
1176 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1177 * (aopForSym): added an optimization to directly store in stack of
1178 the operand of a SEND iCode,
1179 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1180 but as registers instead (AOP_REG) using the fReturnIdx array,
1181 * (pic16_freeAsmop): remove the freed register from the
1182 _G.sregsAlloc field,
1183 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1184 a compare of 'WREG',
1185 * (pic16_popGetTempRegCond): changed function prototype, now
1186 function takes also a bitVector argument v which holds the current
1187 set of registers that are allocated for stack access by aopForSym,
1188 registers allocated in aopForSym for accessing stack symbols are not
1189 any more part of the functions usedRegs field,
1190 * (genCall): some times aopOp is called for a stack variable to be
1191 send, aopForSym might perform the push, if this is true make sure
1192 that genCall doesn't push the variable twice by testing _G.resDirect,
1193 * (genFunction): changed testing for unspecified interrupt number
1194 from 256 to INTNO_UNSPEC,
1195 * modified selection scheme of frame pointer generation. Previously
1196 if function did use local registers a frame pointer was generated,
1197 now a frame pointer is generated only if function has arguments
1198 (that need PLUSW2 register access), or has stack arguments, or the
1199 compiler is not instructed to omit the frame pointer,
1200 * (genEndFunction): before restoring local registers that were saved
1201 in the function preamble, also restore the registers that *might*
1202 have been allocated for stack access,
1203 * (genRet): removed some old comments,
1204 * (genCmp, the active (RN's) version): added a call to the
1205 pic16_genCmp_special function to perform the compare with a more
1206 robust and optimized way,
1207 * (genInline): a feature has been added in inline code generation,
1208 which allows a wildcard variable substitution when writing inline
1209 assembly. Code is incomplete and experimental therefore undocumented,
1210 * (genCast): changed order of aopOp for result and right to allow
1211 aopForSym to directly load the result if possible,
1212 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1213 perform an optimized compare on some selected special occasions,
1214 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1215 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1216 generate an IVT any more,
1217 * src/pic16/main.c (pic16_optionsTable): added command line option
1219 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1220 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1222 * src/pic16/NOTES: Raphael Neider added in list of active developers
1223 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1224 jumptable_end to prevent bug #,
1225 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1226 inCond and outCond fields,
1227 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1228 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1229 turn off register spilling,
1230 * (packRegsForOneUse): synced with other ports' versions although it
1231 is not used currently,
1232 * (pic16_packRegisters): added an optimization while reading
1233 structure bitfields, some registers may be saved (malloc code is
1234 decreased by 80 bytes)
1236 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1238 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1239 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1240 this can be optimized more?
1242 2005-03-10 Raphael Neider <rneider AT web.de>
1244 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1245 genNearPointerGet): (hopefully) fixed access to bitfields via
1246 pointers (p->bitN = x; and x = p->bitN; failed)

1880 Adding support for replacing ljmps with sjmps in jumptables
1881 generated for switch statements. For now you need to set the
1882 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1883 Now 4 algorithms for mcs51 jumptable generation are used:
1884 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1885 addresses loaded pc-relative for up to 112 cases and stack-pushing
1886 target addresses loaded with offset from dptr for up to 256 cases.

1916 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1918 * added libc directory. The current version of LibC contains string
1919 functions, ctype functions and macros and some functions of the
1920 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1921 be extensively tested in the future. Standard disclaimer here.
1922 Library is not automatically build yet. But one can build it by
1923 invoking 'make' inside the libc directory.

1934 * (pic16_storeForReturn): optimized return of 0,
1935 * (genCmp): experimental code for new genCmp which uses PIC18's
1936 special compare&skip instructions. Initial tests fail some times
1937 with variables grater than 1 byte in size, so new code is disabled,
1938 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1940 * (genCast): began a fix to optimize the casting of a bit to another
1941 bit, now assigning a bitfield to another bitfield will fail, sorry,

1955 registers when it shouldn't,
1956 * src/pic16/ralloc.c (allocReg): add preliminary support for
1957 supporting a limited set of temporary registers,
1959 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1961 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

1965 (genFunction): optimize RECEIVE iCodes in reentrant functions
1967 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4878 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4880 * src/SDCCast.c: added an additional type flow in decorateType() of
4881 opposite direction, see feature request #860006; it's enabled at runtime
4882 by setting the environment variable SDCC_NEWTYPEFLOW
4883 * src/SDCCast.h: changed prototype of decorateType()
4884 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4885 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4886 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4887 see feature request #877103

4916 * src/pic/ralloc.h: applied patch from Slade Rich;
4917 added support for multiple code pages and multiple RAM banks on the
4918 PIC 14 port. The ASM files now no longer simply assume all the
4919 code / RAM are in the same page / bank. This means the linker can
4920 safely allocate code/RAM of separate ASM files to different pages/banks.
4921 * doc/sdccman.lyx: added Slade's tips
4922 * src/mcs51/peeph.def: fixed bug #880768

4964 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4966 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4967 loaded with the linker search paths (-L arguments) and the libraries
4968 to be linked with the current source (-l arguments). Changes
4969 currently will affect only the pic16 port.
4970 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4971 include path the port specific paths and port specific libraries,
4972 * gplink command now contains the $3 argument,
4973 * src/pic16/device.h,
4974 * src/pic16/device.c,: structure PIC_device is made public and
4975 renamed to PIC16_device, the same for variable Pics which is renamed

4990 Documenting changes from previous commits.
4991 * configure.in (version 1.56),
4992 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4993 when generating output files to configure the pic16 library,
4994 but now I've commented it out, since gputils aren't installed in the
4995 SF compile farm, so library won't compile
4997 * device/lib/Makefile.in (version 1.56): initially I've added in
4998 target 'all' the prerequestive 'model-pic16' so it compiled the
4999 pic16 library, but now I've commented it out for the same reasons
5001 * added targets 'model-pic16' and 'objects-pic16' to compile the
5003 * added target 'port-specific-objects-pic16' to handle the
5004 generated libraries and copy them into the build/ directory
5005 * added target 'clean-intermediate-pic16' to clean intermediate
5006 files into pic16 directory
5007 * in target 'installdirs' added line to create directory pic16 in
5008 the installation path
5010 * device/include/Makefile.in (version 1.11): in target 'install'
5011 added lines to copy all header files to installation path,
5012 * in target 'installdirs' added line create directory for pic16
5013 headers in the installation path

5028 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5029 option so that it actually works. Made it specific to the z80, since
5030 the gbz80 doesn't have these kinds of I/O ports.
5032 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5034 * device/include/z180.h,

5056 Mainly changes to support compilation of the device libraries
5057 * src/pic16/device.c: stack is allocated via symbol and not
5058 via literal number. The symbol is placed in the corresponding
5059 position of the data ram
5060 * (pic16_dump_section): relocatable and absolute uninitialized
5061 data are now emitted in sorted order to reduce section naming,
5062 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5063 weren't marked as being in the access bank,
5065 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5067 Added portion of GNU PIC Library under the directory
5068 device/include/pic16 and device/lib/pic16. These files
5069 contain the declarations of SFRs for the PIC18Fxx2 devices.
5070 The directory is initialized via configure from toplevel.

5298 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5300 PIC16 port related changes:
5301 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5302 added variable stackPos,
5304 * gen.c: genCall, assignResultValue: added support for
5305 pushing/retrieving function parameters to/from stack,
5306 genFunction,genEndFunction: setup stack frame for the
5308 genAddrOf: will be changed according to bug 863624
5310 * added files genutils.c and genutils.h which contain gen*
5311 debugged and optimised functions extracted from gen.c
5313 * glue.c: added variable 'externs' which holds extern symbols,
5314 pic16emitRegularMap: is modified to properly handle relocatable
5315 symbols under the new scheme,
5316 pic16createInterruptVect: is modified
5317 pic16printPublics: is modified to emit 'global' assembler directives,
5318 added pic16_printExterns to print extern symbols,
5319 pic16glue: initializes stack/frame pointer in the beginning of
5320 the assembly output. Temporary hack, will be corrected later,
5321 because gplink yet does not support stack and SDCC does not
5322 yet support a type of crt0.o object to create the final binary.
5324 * Removed many lines that contain 8051 legacy code.
5325 * The code is finally placed under a 'code' directive.
5326 * Added port specific options.
5328 * _process_pragma: simplified since now we do not need *special*
5329 include file to define SFR registers. But a separate header
5330 will be needed. This will be developed later.
5331 * _pic16_parseOptions: added, parses port specific options:
5332 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5333 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5334 --preplace-udata-with=
5336 * _pic16_setDefaultOptions: modified to initialize section names,
5337 but hack is temporarly out of order since it needs improvement.
5338 * _pic16_genAssemblerPreamble: configuration words are emitted by
5339 their address instead of their name. This part is incomplete and
5340 supports only the 18Fxx2 devices. Other devices will emit an error
5341 during assembly since they do not contain the same set of config
5343 * _pic16_genIVT: is modified,
5345 * pcode.c: added definitions for some hardware registers that are needed
5347 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5348 All PCI entries are updated. Now LFSR is supported.
5349 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5350 * added pic16_newpCodeOpLit2 to support instructions with
5351 two literal arguments
5352 * pic16_pCode2str: corrected code that emits assembler instructions
5353 with two literal operands and those that have an access bit modifier
5354 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5355 this fixes a bug which caused some labels to be lost, when an
5356 assembler directive was added, i.e. banksel,
5357 * pic16_FixRegisterBanking: improved logic that causes the insertion
5359 * InlineFunction: functions that are called once, are not any more
5360 inlined. This can be a port option in the future,
5362 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5364 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5365 hold the corresponding uninitialized symbols,
5366 * pic16_allocProcessorRegister: registers have explicit marked the
5368 * pic16_allocInternalRegister: registers are explicit marked as
5370 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5371 processing list, so bit registers were lost,
5374 * ralloc.h: added field 'accessBank' and original symbol operand
5375 in register definition,
5376 * removed the field isMapped from register definition,
5378 ** Several functions have been removed from various sources:
5379 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5380 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5381 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5382 pic16_assignRelocatableRegisters
5384 ** others have been introduced:
5385 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5386 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5388 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5390 * support/scripts/inc2h.pl: changed definition of BIT_AT
5391 to emit 'sbit at' instead of 'bit at'. This was a request.
5393 PIC16 port related preliminary changes:
5394 * gen.c: prefixed function popRegFromString with
5395 pic16_ and all references to it corrected
5396 * pcode.c: all pic16_pc_* hardware registers prefixed
5397 with underscore (_),
5398 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5399 * ralloc.c: newReg(): when register is REG_SFR then
5400 set address to rIdx,
5401 pic16_allocProcessorRegister(): marks register wasUsed=0
5402 pic16_writeUsedRegs(): added a call to assign processor
5403 registers via pic16_assignFixedRegisters
5405 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5407 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5408 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5409 variables in unused register banks. Also the SSEG is placed
5410 wherever there is enough space for it, and IDATA can be anywhere
5411 in internal RAM. For now compile using -Wl-Y[stack_size].
5412 The mem file is different for this option as well, since it
5413 makes no sense of talking about DSEG lenght.
5415 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5417 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5418 in certain cases, e.g. when ROM assignment, patch provided
5419 from Albert den Haan.

5660 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5662 * src/SDCCast.c (decorateType): disabled a transformation I added in
5663 revision 1.188 (access to fields of a structure at an absolute address);
5664 it breaks with bitfields, extern declarations, and gcse analysis.
5665 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5666 could be assigned through a pointer, so don't complain.
5667 * src/SDCCast.c (astErrors),

5771 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
5772 uninitialized variables) for the mcs51. Set environment variable

5774 xdata initialization slightly shorter
5776 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6423 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6424 fetching of the pointer
6425 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6426 copied from genNearPointerSet()
6427 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6428 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6444 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6445 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6446 type for bits was changed. It resulted in bit variables becoming
6447 global, which is not permitted in PIC 14 assembly output.
6449 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6451 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6464 A few small changes that speed up the peephole optimizer.
6468 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6470 Try to make the peephole optimizer smarter by maintaining
6471 an association between the assembly source code and the
6472 iCodes that originated them. Put this information to use
6473 with a new peephole rule condition "notVolatile" so that
6474 the rules can be aggressive yet still safe.
6479 * src/mcs51/peeph.def
6481 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6485 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6486 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6487 if the left or right operand symbols have the accuse flag set.
6489 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6491 Changed the type of the result of the ! (NOT) operator to char;
6492 previously it returned the same type as the source. This allows
6493 us to eliminate all the genFloatNot functions (all of its target
6494 implementations were very buggy) since !float can use the same
6497 * src/SDCCicode.c (ast2iCode): ! returns char

6506 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6507 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6508 during interrupts. Ensure WSAVE is located at a shared bank address.
6509 2. Fixed page selection in some places
6510 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6511 the registers name strings.
6512 4. Fixed "signed / unsigned compare" compiler warnings.
6513 5. The PIC port manages its own allocation of the general purpose
6514 registers, but makes no attempt to reuse them. As a result when
6515 compiling it soon runs out of general purpose registers. Some
6516 additional code was added to the files pcode.c and device.c to walk
6517 through the function call tree and rename the registers so that they
6527 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6528 genPlus() & genMinus() when the result is the same as left or right

6534 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6536 Made bitfield a distinct type from bit so that bitfields
6537 convert as per ANSI C and bits retain their traditional
6538 boolean style behaviour. Implemented bitfield support in
6546 * src/ds390/gen.c: bit v bitfield split
6547 * src/z80/gen.c: New support for bitfields
6548 * support/regression/tests/bitfields.c: reenabled z80,
6551 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6553 Rules 246.x, 247.x relate to bitfields, the others speed up
6554 access to xdata mapped I/O devices.
6556 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6558 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6560 Cleaned up genPackBits and genUnpackBits and added two helper
6561 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6562 for literal assignments in genPackBits (thanks to Frieder for
6568 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6570 Fixed bug #748310 (pointer to function type mishandled when the
6571 function name is omitted). Also fixed a SIGSEGV when a function
6572 attribute (reentrant, etc) is used on a non-function or on a
6573 function but misplaced before the parameter list.
6575 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6577 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6578 * support/Util/SDCCerr.h,

6600 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6602 Made the constant following the "interrupt" keyword optional. If
6603 omitted, the function will not automatically be given an entry
6604 in the interrupt vector table (similar to #pragma NOIV, but
6605 less syntacticly kludgy). The interrupt number is also now
6606 range checked. Also fixed a bug in the high order bit example

6620 * src/SDCCicode.c (operandOperation): rewritten some ops
6621 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6622 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6624 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6625 be re-activated by defining REDUCE_LITERALS)
6626 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6627 unsigned, but are signed by default
6628 * src/SDCCval.c (constVal): rearranged
6629 * src/SDCCval.c (valMod): preliminary fix
6630 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6672 constants are unsigned; added recognition of "u" flag for unsigned
6673 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6674 * src/SDCCval.c (valDiv, valMod): fixed signdness
6675 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6676 signedness of modulo, left and right shift

7085 Using pdflatex this will give you a hyperlinked pdf file with
7086 bookmarks. (prepend '%' before /usepackage if this breaks something)

7135 * src/SDCCmain.c: linkOptions is changed to set *,
7136 added if/endif conditional macros to remove options help
7137 messages from optionsTable when a port is not configured, added
7138 support for the PIc16 port in the ports table, when executing
7139 the compiler with no port specified on command line, a default
7140 port is selected with the new macro DEFAULT_PORT which is
7141 defined in port.h, in setDefaultOptions() linkOptions is removed
7142 from initialization assignment, since now it is a set,
7143 parseCmdLine uses setParseWithComma for linkOptions, in
7144 linkEdit() linkOptions are accessed with new function indexSet()
7145 which returns the i'th item of a set variable. See SDCCset.c, in
7146 linkEdit() when calling buildCmdLine(), added linkOptions as
7147 last argument. Now users can pass arguments to gplink via the
7148 -Wl option, main() uses pic16glue() to glue up pic16 programs

7160 * src/pic16/glue.c: commented out some error producing lines
7161 * src/pic16/main.c: __config directives are commented out to stop
7162 gpasm complaining and test the linkage with gplink, _linkCmd and
7163 _asmCmd changed to be more gplink and gpasm friendly
7164 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7165 produced an error when parsed, peep rule 12 is added to utilize
7166 movff, but it is commented out since the pCode does not support
7167 yet a command with 2 address arguments
7169 2003-05-18 <johan AT balder>
7171 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7172 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7198 2003-05-11 Borut Razem <borut.razem AT siol.net>
7200 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7201 the path of bin directory, so that PATH is the only env. variable, which has to be set
7202 in case of standard installation.
7203 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8255 * SDCClrange.h: exposed setFromRange() and setToRange()
8256 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8257 packRegsForAccUse() (bug 542397)
8258 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8259 multiple times and emitting the fetch operations more than once
8260 added aopGetUsesAcc() function to allow binary operators to
8261 fetch their operands in the correct order; made genMinus() emit
8262 compact code for X = LITERAL - Y
8264 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8265 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8266 sprintf() in line 1267.
8268 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8269 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8272 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8273 Changes to aslink (All the changes are marked with 'JCF'):
8275 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8278 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8279 area BSEG. Also moves, if possible, the DATA area down into the internal
8280 ram so more space is available.
8282 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8285 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8286 not bytes. Function summary() which creates a memory usage summary
8287 file with extension .mem. Reports of overlaping stack and small stack
8288 size. If the space for the stack is less than 16 bytes aslink trows a
8291 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8292 the 8051. Option 'y' for memory summary output file.
8294 Changes to sdcc (All the changes are marked with 'JCF'):
8296 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8298 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8299 overlaying area for it (uses RegBankUsed[4]).
8301 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8302 bank zero as used by default. By default aslink locates the stack
8303 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8304 the creation of the .mem file. Delegates the allocation of data area
8305 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8306 the begining of the stack area to aslink.
8308 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8309 glue() in SDCCglue.c creates an area for it.
8311 2002-09-03 Borut Razem <borut.razem AT siol.net>
8312 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8313 sdcc/src/pic/glue.c:
8314 introduced atexit() handler for teporay files removal in case of
8315 errors, assertions, ...
8317 2002-08-29 Borut Razem <borut.razem AT siol.net>
8318 * sdcc/support/cpp2/auto-host_vc_in.h:
8319 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8320 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8321 Maybe there is a similar problem with BORLANDC? It should be checked!
8323 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8324 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8325 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8326 was not executed, and the compiler (cl) launched a warning:
8327 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8329 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8330 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8332 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8333 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8335 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8336 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8337 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8338 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8339 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8340 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8341 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8342 - added Release configuration in VS projects
8343 - review of compiler an linker options
8344 - VC .exe files are generated in bin_vc directory, not to interfere
8345 with binaries generated from other projects (cygwin, mingw, bcc ...)
8347 * sdcc/src/yacc.dsp: added
8349 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8350 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8351 and insert the version number definitions from .version
8353 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8355 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8356 added - genarate auto-host.h using auto-host_vc_in.h as template
8359 removed from CVS, generated automatically
8361 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8362 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8364 2002-08-11 Borut Razem <borut.razem AT siol.net>
8365 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8367 2002-08-10 Borut Razem <borut.razem AT siol.net>
8368 * src/SDCCmain.c (main):
8369 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8370 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8371 The consequence was that some temporary files were not removed.
8374 unification of code in functions tempfilename() and tempfile():
8375 function tempnam() is defined in Visual Studio 6.0 and .NET
8377 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8379 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8380 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8381 - removed compiler command line option /WX: Treats all warnings as errors
8382 - update a list of source files, included into the project
8384 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8385 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8386 changed project type to Generic Project so that can be correcly converted to VS.NET project
8388 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8390 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8392 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8394 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8395 added return 0 statements after assert() to make compiler happy
8397 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8398 added newline in the def file to keep MSC compiler satisfied
8400 * sdcc/src/z80/gen.c:
8401 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8402 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8403 - solved MSC error in function aopDump()
8405 * sdcc_vc.h: define PREFIX as "\\sdcc"
8407 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8408 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8411 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8412 - Rewrote the register banking algorithm.
8413 - Added pCode live-range analysis to registers (for now, only non-used and
8414 singly-used registers optimized away)
8416 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8418 * 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.

8447 2002-03-28 Johan Knol <johan AT balder>
8449 * src/SDCCval.c: fixed bug #532436
8451 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8453 Added "char *Processor" field to the port structure.
8456 Added -p option. Allows port dependent processor to be specified.
8459 Initialized the new field char *Processor field to NULL in all ports
8462 Compiler generated registers for interrupt context saving
8463 were not getting allocated.
8465 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8468 Fixed left shift. Will promote the left side of a left shift
8469 if a) left shifting more than size of operand or b) when assigned
8470 to something size > size of left side
8472 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8474 tons of changes. Register allocation has been
8475 rewritten. Added customization for the various PICs. Flow
8476 analysis is restructured. ...
8482 Added. device.c is a PIC port hack to accomodate variations
8485 2002-03-13 Michael Hope <michaelh AT vroom>
8487 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8580 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8582 * sdcc/src/SDCCloop.c:
8583 Previous fix was not good. basic blocks that have "break" or "return" are
8584 not really partof a loop , but live ranges used in these blocks should
8585 be live thru the entire loop, so set partOfLoop but don't add them to
8588 2002-02-21 <johan AT FRIJA>
8590 * src/SDCCcse.c: fixed bug #514308
8592 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
8595 Fixed BUG #519583. If a conditional block ended in a return/break
8596 statement inside a loop, it was not being considered part of the loop.
8598 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8600 2002-02-10 Karl Bongers <karl AT turbobit.com>
8603 Fixed up SDCDB debugger somewhat. Updated debugger/README
8604 with lots of comments and notes.
8606 * device/examples/test2.c:
8607 Fix bug, "red" variable not being initialized(compiler complained).
8609 * device/examples/Makefile, examples/test3.c:

8611 for use as a multiple module SDCDB test case.
8613 * sim/ucsim/cmd.src/cmdset.cc:
8614 Took out debug printfs in ucsim "next" command.
8617 Karl and Johan start ucsim XA support. Most dissassembly working,
8618 about 75% emulation done(plenty of work remaining).
8620 * sim/ucsim/z80.src:
8621 Add Z80 support to ucsim, add test-ucz80 regression test,
8622 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

8658 set preprocessor defines (depending on options)
8660 * src/SDCCicode.c, src/SDCCicode.h:
8661 changes made to handle multiple sends & receives
8664 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
