2255 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2257 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2258 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2260 One basic decision: e.g. src/clean.mk includes further files. In order
2261 to make this work there are two solutions:
2262 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2263 run configure on them. This way they can use
2264 'include $(srcdir)/port-clean.mk'
2265 - always include clean.mk by the Makefile at the same level. To avoid
2266 that `make clean` tries to include and build Makefile.dep the
2267 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2268 implemented, because now even `make uninstall` doesn't create
2269 Makefile.in. clean.mk could be eliminated by pasting it in
2272 * debugger/mcs51/Makefile.in: build own objects from library sources
2273 (SLIB, SDCC) in current directory
2275 * configure, configure.in: renamed --disable-device-lib-build in
2276 --disable-device-lib; added --enable-doc, the required tools are
2277 searched by configure; added result message; the toolchain for the
2278 belonging ports are now only built, if the port is enabled.
2280 * support/regression/*: all output is written in directory gen, because
2281 the fwk and ports directories don't livet in the build tree using vpath
2283 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2284 --disable-device-lib, added --enable-doc, added section VPATH
2286 * sim/ucsim/configure.in,
2287 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2288 z80 are enabled by default
2290 2006-04-24 Raphael Neider <rneider AT web.de>
2292 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2293 to config word, "pic14_"-prefixed some extern functions
2294 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2295 config word has been found
2296 * src/pic/device.h: added prototypes
2297 * src/pic/pcode.c: added "pic14_"-prefix where needed
2298 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2300 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2603 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2605 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2606 call to allocReg, not by manually allocating a new one,

2608 allocating functions mark all registers as free. This eliminates some
2609 side effects resulting from peephole parser done earlier in the backbone
2611 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2661 2006-03-06 Borut Razem <borut.razem AT siol.net>
2663 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2664 made the linker quiet
2666 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2668 * src/pic16/gen.c (genPcall): fixed bug #1443644
2669 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2670 which dumps before the function entry point a data byte which represents
2671 the number of the local variables used by the specified function, added
2672 'xinst' for initial support for Extended Instruction Support,
2673 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2674 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2675 port->fun_prefix anymore (may change later),
2676 (genFunction, genEndFunction): do not store/restore local registers for
2677 _main (this should take care the --main-return command line option in
2679 (genOr): removed some legacy pic-port instructions,
2680 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2681 performing operations with SFR's causes data to be written more than
2682 once to each SFR. Perhaps SFRs should be handled in special cases...
2683 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

2690 (deassignLRs): *** perhaps the most important change, old 'for' code
2691 (commented out for reference), didn't account for some registers which
2692 were left marked 'not free' after a pointer operation. The change
2693 reduces register usage a lot in some cases

5051 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5053 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5055 * device/lib/printf_large.c: removed inline assembly for portability and
5056 readability. Use printf_fast if speed or size are more important.
5057 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5058 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5060 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5062 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5063 prevent compiler warning
5065 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5067 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5068 moved to level 0 and declared as static. Also they are explicit
5069 placed in access bank. This was necessery because some times they
5070 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5071 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5072 optimizations. Currently only compare to unsigned char is implemented,
5073 * src/pic16/gen.c: added fReturnIdx array,
5074 * (struct resolvedIfx) is moved to gen.h and made public,
5075 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5076 * (aopForSym): added an optimization to directly store in stack of
5077 the operand of a SEND iCode,
5078 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5079 but as registers instead (AOP_REG) using the fReturnIdx array,
5080 * (pic16_freeAsmop): remove the freed register from the
5081 _G.sregsAlloc field,
5082 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5083 a compare of 'WREG',
5084 * (pic16_popGetTempRegCond): changed function prototype, now
5085 function takes also a bitVector argument v which holds the current
5086 set of registers that are allocated for stack access by aopForSym,
5087 registers allocated in aopForSym for accessing stack symbols are not
5088 any more part of the functions usedRegs field,
5089 * (genCall): some times aopOp is called for a stack variable to be
5090 send, aopForSym might perform the push, if this is true make sure
5091 that genCall doesn't push the variable twice by testing _G.resDirect,
5092 * (genFunction): changed testing for unspecified interrupt number
5093 from 256 to INTNO_UNSPEC,
5094 * modified selection scheme of frame pointer generation. Previously
5095 if function did use local registers a frame pointer was generated,
5096 now a frame pointer is generated only if function has arguments
5097 (that need PLUSW2 register access), or has stack arguments, or the
5098 compiler is not instructed to omit the frame pointer,
5099 * (genEndFunction): before restoring local registers that were saved
5100 in the function preamble, also restore the registers that *might*
5101 have been allocated for stack access,
5102 * (genRet): removed some old comments,
5103 * (genCmp, the active (RN's) version): added a call to the
5104 pic16_genCmp_special function to perform the compare with a more
5105 robust and optimized way,
5106 * (genInline): a feature has been added in inline code generation,
5107 which allows a wildcard variable substitution when writing inline
5108 assembly. Code is incomplete and experimental therefore undocumented,
5109 * (genCast): changed order of aopOp for result and right to allow
5110 aopForSym to directly load the result if possible,
5111 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5112 perform an optimized compare on some selected special occasions,
5113 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5114 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5115 generate an IVT any more,
5116 * src/pic16/main.c (pic16_optionsTable): added command line option
5118 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5119 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5121 * src/pic16/NOTES: Raphael Neider added in list of active developers
5122 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5123 jumptable_end to prevent bug #,
5124 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5125 inCond and outCond fields,
5126 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5127 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5128 turn off register spilling,
5129 * (packRegsForOneUse): synced with other ports' versions although it
5130 is not used currently,
5131 * (pic16_packRegisters): added an optimization while reading

5779 Adding support for replacing ljmps with sjmps in jumptables
5780 generated for switch statements. For now you need to set the
5781 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5782 Now 4 algorithms for mcs51 jumptable generation are used:
5783 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5784 addresses loaded pc-relative for up to 112 cases and stack-pushing
5785 target addresses loaded with offset from dptr for up to 256 cases.

5817 * added libc directory. The current version of LibC contains string
5818 functions, ctype functions and macros and some functions of the
5819 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5820 be extensively tested in the future. Standard disclaimer here.
5821 Library is not automatically build yet. But one can build it by
5822 invoking 'make' inside the libc directory.

5833 * (pic16_storeForReturn): optimized return of 0,
5834 * (genCmp): experimental code for new genCmp which uses PIC18's
5835 special compare&skip instructions. Initial tests fail some times
5836 with variables grater than 1 byte in size, so new code is disabled,
5837 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5839 * (genCast): began a fix to optimize the casting of a bit to another
5840 bit, now assigning a bitfield to another bitfield will fail, sorry,

5849 and 1 for banking instruction,
5850 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5851 caused stop processing pCodes after a inline assembly block,
5852 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5854 registers when it shouldn't,
5855 * src/pic16/ralloc.c (allocReg): add preliminary support for
5856 supporting a limited set of temporary registers,

8866 loaded with the linker search paths (-L arguments) and the libraries
8867 to be linked with the current source (-l arguments). Changes
8868 currently will affect only the pic16 port.
8869 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8870 include path the port specific paths and port specific libraries,
8871 * gplink command now contains the $3 argument,
8872 * src/pic16/device.h,
8873 * src/pic16/device.c,: structure PIC_device is made public and
8874 renamed to PIC16_device, the same for variable Pics which is renamed

8889 Documenting changes from previous commits.
8890 * configure.in (version 1.56),
8891 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8892 when generating output files to configure the pic16 library,
8893 but now I've commented it out, since gputils aren't installed in the
8894 SF compile farm, so library won't compile
8896 * device/lib/Makefile.in (version 1.56): initially I've added in
8897 target 'all' the prerequestive 'model-pic16' so it compiled the
8898 pic16 library, but now I've commented it out for the same reasons
8900 * added targets 'model-pic16' and 'objects-pic16' to compile the
8902 * added target 'port-specific-objects-pic16' to handle the
8903 generated libraries and copy them into the build/ directory
8904 * added target 'clean-intermediate-pic16' to clean intermediate
8905 files into pic16 directory
8906 * in target 'installdirs' added line to create directory pic16 in

8910 added lines to copy all header files to installation path,
8911 * in target 'installdirs' added line create directory for pic16
8912 headers in the installation path

9143 * as/mcs51/lkmain.c: Help about -Y option
9144 * as/mcs51/lkarea.c: Fixed gcc warnings
9146 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9148 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
9150 * support/valdiag/tests/overflow.c: added
9151 * src/SDCCast.c (decorateType),
9152 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9153 LEFT_OP (left shift)
9155 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9157 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9158 (default behaviour).
9160 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9162 A python script to validate compiler diagnostic messages. It can be
9163 used to verify that sdcc complains about bad c source code and
9164 gives a good location of the error.
9165 * support/valdiag/Makefile,
9166 * support/valdiag/valdiag.py,
9167 * support/valdiag/tests/*
9169 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9171 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9172 * src/SDCCsymt.c (newEnumType),
9174 * support/Util/SDCCerr.c,
9175 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9177 * support/regression/tests/enum.c: added test for enum values that
9178 require at least 2 bytes of storage.
9180 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9182 * src/common.h: added ifndef/define/endif macros
9183 around the header file.
9184 Bug reported from Jesus Calvino-Fraga
9186 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9188 * sdcc.spec: updated
9189 * device/include/Makefile.in: don't install CVS directories
9190 * device/lib/Makefile.in: added removal of CVS directories after install
9191 * doc/Makefile: fixed install, added local_icons
9192 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9193 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9194 * src/ds390/gen.c (genRightShift): fixed bug #870788
9195 * src/SDCCast.c (decorateType): fixed bug #870781
9197 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9199 PIC16 port related changes:
9200 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9201 added variable stackPos,
9203 * gen.c: genCall, assignResultValue: added support for
9204 pushing/retrieving function parameters to/from stack,
9205 genFunction,genEndFunction: setup stack frame for the
9207 genAddrOf: will be changed according to bug 863624
9209 * added files genutils.c and genutils.h which contain gen*
9210 debugged and optimised functions extracted from gen.c
9212 * glue.c: added variable 'externs' which holds extern symbols,
9213 pic16emitRegularMap: is modified to properly handle relocatable
9214 symbols under the new scheme,
9215 pic16createInterruptVect: is modified
9216 pic16printPublics: is modified to emit 'global' assembler directives,
9217 added pic16_printExterns to print extern symbols,
9218 pic16glue: initializes stack/frame pointer in the beginning of
9219 the assembly output. Temporary hack, will be corrected later,
9220 because gplink yet does not support stack and SDCC does not
9221 yet support a type of crt0.o object to create the final binary.
9223 * Removed many lines that contain 8051 legacy code.
9224 * The code is finally placed under a 'code' directive.
9225 * Added port specific options.
9227 * _process_pragma: simplified since now we do not need *special*
9228 include file to define SFR registers. But a separate header
9229 will be needed. This will be developed later.
9230 * _pic16_parseOptions: added, parses port specific options:
9231 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9232 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9233 --preplace-udata-with=
9235 * _pic16_setDefaultOptions: modified to initialize section names,
9236 but hack is temporarly out of order since it needs improvement.
9237 * _pic16_genAssemblerPreamble: configuration words are emitted by
9238 their address instead of their name. This part is incomplete and
9239 supports only the 18Fxx2 devices. Other devices will emit an error
9240 during assembly since they do not contain the same set of config
9242 * _pic16_genIVT: is modified,
9244 * pcode.c: added definitions for some hardware registers that are needed
9246 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9247 All PCI entries are updated. Now LFSR is supported.
9248 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9249 * added pic16_newpCodeOpLit2 to support instructions with
9250 two literal arguments
9251 * pic16_pCode2str: corrected code that emits assembler instructions
9252 with two literal operands and those that have an access bit modifier
9253 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9254 this fixes a bug which caused some labels to be lost, when an
9255 assembler directive was added, i.e. banksel,
9256 * pic16_FixRegisterBanking: improved logic that causes the insertion
9258 * InlineFunction: functions that are called once, are not any more
9259 inlined. This can be a port option in the future,
9261 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9263 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9264 hold the corresponding uninitialized symbols,
9265 * pic16_allocProcessorRegister: registers have explicit marked the
9267 * pic16_allocInternalRegister: registers are explicit marked as
9269 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9270 processing list, so bit registers were lost,
9273 * ralloc.h: added field 'accessBank' and original symbol operand
9274 in register definition,
9275 * removed the field isMapped from register definition,
9277 ** Several functions have been removed from various sources:
9278 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9279 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9280 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9281 pic16_assignRelocatableRegisters
9283 ** others have been introduced:
9284 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9285 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9287 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9289 * support/scripts/inc2h.pl: changed definition of BIT_AT
9290 to emit 'sbit at' instead of 'bit at'. This was a request.
9292 PIC16 port related preliminary changes:
9293 * gen.c: prefixed function popRegFromString with
9294 pic16_ and all references to it corrected
9295 * pcode.c: all pic16_pc_* hardware registers prefixed
9296 with underscore (_),
9297 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9298 * ralloc.c: newReg(): when register is REG_SFR then
9299 set address to rIdx,
9300 pic16_allocProcessorRegister(): marks register wasUsed=0
9301 pic16_writeUsedRegs(): added a call to assign processor
9302 registers via pic16_assignFixedRegisters
9304 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9306 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9307 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9308 variables in unused register banks. Also the SSEG is placed
9309 wherever there is enough space for it, and IDATA can be anywhere
9310 in internal RAM. For now compile using -Wl-Y[stack_size].
9311 The mem file is different for this option as well, since it
9312 makes no sense of talking about DSEG lenght.
9314 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9316 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9317 in certain cases, e.g. when ROM assignment, patch provided
9318 from Albert den Haan.
9320 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9463 * src/mcs51/peephole.def,
9464 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9465 (allows non-interrupt and interrupt code to safely compete for a resource

9476 multiply defined with mismatching "at" address.
9478 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9480 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

9559 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9561 * src/SDCCast.c (decorateType): disabled a transformation I added in
9562 revision 1.188 (access to fields of a structure at an absolute address);
9563 it breaks with bitfields, extern declarations, and gcse analysis.
9564 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9565 could be assigned through a pointer, so don't complain.
9566 * src/SDCCast.c (astErrors),
9568 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10148 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10149 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10150 (ralloc doesn't intentionally do this now, but perhaps later)
10151 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10152 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

10166 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10167 of const struct should be treated as if const themselves)
10169 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10171 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10186 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10187 and restore of EA so that stack offsets to parameters are
10188 correct when using both critical and reentrant/stack-auto.

10203 * src/SDCCsymt.c (sclsFromPtr),
10205 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10206 support for standard C idiom of memory mapped variables; for
10207 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10208 to xdata int at 0x1234 tempvar = 1.
10209 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
10210 provided by Akiya ISHIDA

10226 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10228 Fixed bug #621531 (const & volatile confusion in the type chain).
10229 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10230 refer to the const or volatile state of the pointer itself.
10242 * src/pic16/ralloc.c
10243 * support/regression/tests/const.c
10245 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10247 When checking for duplicated modules, use absolute paths

10295 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10296 pcoderegs.h, ralloc.c, ralloc.h
10297 * main.c: added top header and GPL license notice

10300 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10302 * device/lib/_mullong.c: replaced int by short for gcc
10304 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10306 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10307 and JUMPTABLE iCodes properly now (worked by accident before)
10308 * src/mcs51/gen.c (leftRightUseAcc),
10309 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10310 iCode properly now. Use getSize instead of nRegs since a & b
10311 aren't part of the nRegs tally.
10313 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10315 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10321 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10322 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10323 fetching of the pointer
10324 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10325 copied from genNearPointerSet()
10326 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10327 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10328 If they pop r0/r1 they must be called in the opposite order than aopOp().
10329 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10330 (resp. --stack-auto), prepared for --xstack
10332 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10334 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10336 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10341 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10343 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10344 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10345 type for bits was changed. It resulted in bit variables becoming
10346 global, which is not permitted in PIC 14 assembly output.
10348 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10350 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10352 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10354 Z80 and MCS51 linkers complaint if a public symbol is defined
10355 in more than one library module:

10361 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10363 A few small changes that speed up the peephole optimizer.
10367 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10369 Try to make the peephole optimizer smarter by maintaining
10370 an association between the assembly source code and the
10371 iCodes that originated them. Put this information to use
10372 with a new peephole rule condition "notVolatile" so that
10373 the rules can be aggressive yet still safe.
10378 * src/mcs51/peeph.def
10380 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10384 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10385 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10386 if the left or right operand symbols have the accuse flag set.
10388 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10390 Changed the type of the result of the ! (NOT) operator to char;
10391 previously it returned the same type as the source. This allows
10392 us to eliminate all the genFloatNot functions (all of its target
10393 implementations were very buggy) since !float can use the same
10396 * src/SDCCicode.c (ast2iCode): ! returns char
10397 * src/mcs51/gen.c (genNot, genNotFloat),
10398 * src/ds390/gen.c (genNot, genNotFloat),
10399 * src/z80/gen.c (genNot, genNotFloat),
10400 * src/pic/gen.c (genNot, genNotFloat),
10401 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10405 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10406 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10407 during interrupts. Ensure WSAVE is located at a shared bank address.
10408 2. Fixed page selection in some places
10409 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10410 the registers name strings.
10411 4. Fixed "signed / unsigned compare" compiler warnings.
10412 5. The PIC port manages its own allocation of the general purpose
10413 registers, but makes no attempt to reuse them. As a result when
10414 compiling it soon runs out of general purpose registers. Some
10415 additional code was added to the files pcode.c and device.c to walk
10416 through the function call tree and rename the registers so that they
10426 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10427 genPlus() & genMinus() when the result is the same as left or right
10429 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10433 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10435 Made bitfield a distinct type from bit so that bitfields
10436 convert as per ANSI C and bits retain their traditional
10437 boolean style behaviour. Implemented bitfield support in
10445 * src/ds390/gen.c: bit v bitfield split
10446 * src/z80/gen.c: New support for bitfields
10447 * support/regression/tests/bitfields.c: reenabled z80,
10450 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10452 Rules 246.x, 247.x relate to bitfields, the others speed up
10453 access to xdata mapped I/O devices.
10455 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10457 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10459 Cleaned up genPackBits and genUnpackBits and added two helper
10460 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10461 for literal assignments in genPackBits (thanks to Frieder for
10467 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10469 Fixed bug #748310 (pointer to function type mishandled when the
10470 function name is omitted). Also fixed a SIGSEGV when a function
10471 attribute (reentrant, etc) is used on a non-function or on a
10472 function but misplaced before the parameter list.
10474 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10476 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10477 * support/Util/SDCCerr.h,
10478 * support/Util/SDCCerr.c: Added func attr misuse error msg
10480 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10482 Fixed bug #787649 by anonymous
10483 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10484 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10486 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10488 Fixed numerous bitfield problems.
10490 * src/SDCC.y: More bitfield related error checking

10499 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10501 Made the constant following the "interrupt" keyword optional. If
10502 omitted, the function will not automatically be given an entry
10503 in the interrupt vector table (similar to #pragma NOIV, but
10504 less syntacticly kludgy). The interrupt number is also now
10505 range checked. Also fixed a bug in the high order bit example

10513 * support/Util/SDCCerr.h
10516 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10519 * src/SDCCicode.c (operandOperation): rewritten some ops
10520 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10521 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10523 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10524 be re-activated by defining REDUCE_LITERALS)
10525 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10526 unsigned, but are signed by default
10527 * src/SDCCval.c (constVal): rearranged
10528 * src/SDCCval.c (valMod): preliminary fix
10529 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10567 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
10569 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10570 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10571 constants are unsigned; added recognition of "u" flag for unsigned
10572 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10573 * src/SDCCval.c (valDiv, valMod): fixed signdness
10574 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10575 signedness of modulo, left and right shift

10618 * support/librarian/configure.in
10619 * support/librarian/config_in.h
10620 * support/librarian/Makefile.in

10626 Messed up 'configure', so revert to previous version:
10630 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
10632 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
10633 there, while the mantissa of a double is "only" 53 bits wide.
10635 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11036 messages from optionsTable when a port is not configured, added
11037 support for the PIc16 port in the ports table, when executing
11038 the compiler with no port specified on command line, a default
11039 port is selected with the new macro DEFAULT_PORT which is
11040 defined in port.h, in setDefaultOptions() linkOptions is removed
11041 from initialization assignment, since now it is a set,
11042 parseCmdLine uses setParseWithComma for linkOptions, in
11043 linkEdit() linkOptions are accessed with new function indexSet()
11044 which returns the i'th item of a set variable. See SDCCset.c, in
11045 linkEdit() when calling buildCmdLine(), added linkOptions as
11046 last argument. Now users can pass arguments to gplink via the
11047 -Wl option, main() uses pic16glue() to glue up pic16 programs

11061 gpasm complaining and test the linkage with gplink, _linkCmd and
11062 _asmCmd changed to be more gplink and gpasm friendly
11063 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11064 produced an error when parsed, peep rule 12 is added to utilize
11065 movff, but it is commented out since the pCode does not support
11066 yet a command with 2 address arguments

12107 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12108 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

12118 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12119 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12125 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12126 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12128 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12129 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12131 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12133 * in /sdcc/as/mcs51/ changed these files in order to create an
12134 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12135 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12136 following files to include the previous two files: aslink.dsp,
12137 Makefile.aslink, Makefile.bcc, and Makefile.in.
12139 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12140 .adb instead of .cdb
12142 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12144 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12145 value from option --iram-size.
12147 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12149 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12152 2002-09-18 <wiml AT hhhh.org>
12154 * SDCClrange.h: exposed setFromRange() and setToRange()
12155 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12156 packRegsForAccUse() (bug 542397)
12157 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12158 multiple times and emitting the fetch operations more than once
12159 added aopGetUsesAcc() function to allow binary operators to
12160 fetch their operands in the correct order; made genMinus() emit
12161 compact code for X = LITERAL - Y
12163 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12164 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12165 sprintf() in line 1267.
12167 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12168 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12171 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12172 Changes to aslink (All the changes are marked with 'JCF'):
12174 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12177 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12178 area BSEG. Also moves, if possible, the DATA area down into the internal
12179 ram so more space is available.
12181 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12184 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12185 not bytes. Function summary() which creates a memory usage summary
12186 file with extension .mem. Reports of overlaping stack and small stack
12187 size. If the space for the stack is less than 16 bytes aslink trows a
12190 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12191 the 8051. Option 'y' for memory summary output file.
12193 Changes to sdcc (All the changes are marked with 'JCF'):
12195 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12197 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12198 overlaying area for it (uses RegBankUsed[4]).
12200 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12201 bank zero as used by default. By default aslink locates the stack
12202 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12203 the creation of the .mem file. Delegates the allocation of data area
12204 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12205 the begining of the stack area to aslink.
12207 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12208 glue() in SDCCglue.c creates an area for it.
12210 2002-09-03 Borut Razem <borut.razem AT siol.net>
12211 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12212 sdcc/src/pic/glue.c:
12213 introduced atexit() handler for teporay files removal in case of
12214 errors, assertions, ...
12216 2002-08-29 Borut Razem <borut.razem AT siol.net>
12217 * sdcc/support/cpp2/auto-host_vc_in.h:
12218 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12219 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12220 Maybe there is a similar problem with BORLANDC? It should be checked!
12222 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12223 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12224 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12225 was not executed, and the compiler (cl) launched a warning:
12226 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12228 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12229 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12231 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12232 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12234 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12235 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12236 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12237 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12238 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12239 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12240 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12241 - added Release configuration in VS projects
12242 - review of compiler an linker options
12243 - VC .exe files are generated in bin_vc directory, not to interfere
12244 with binaries generated from other projects (cygwin, mingw, bcc ...)
12246 * sdcc/src/yacc.dsp: added
12248 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12249 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12250 and insert the version number definitions from .version
12252 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12254 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12255 added - genarate auto-host.h using auto-host_vc_in.h as template
12258 removed from CVS, generated automatically
12260 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12261 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12263 2002-08-11 Borut Razem <borut.razem AT siol.net>
12264 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12266 2002-08-10 Borut Razem <borut.razem AT siol.net>
12267 * src/SDCCmain.c (main):
12268 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12269 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12270 The consequence was that some temporary files were not removed.
12273 unification of code in functions tempfilename() and tempfile():
12274 function tempnam() is defined in Visual Studio 6.0 and .NET
12276 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12278 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12279 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12280 - removed compiler command line option /WX: Treats all warnings as errors
12281 - update a list of source files, included into the project
12283 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12284 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12285 changed project type to Generic Project so that can be correcly converted to VS.NET project
12287 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12289 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12291 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12293 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12294 added return 0 statements after assert() to make compiler happy
12296 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12297 added newline in the def file to keep MSC compiler satisfied
12299 * sdcc/src/z80/gen.c:
12300 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12301 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12302 - solved MSC error in function aopDump()
12304 * sdcc_vc.h: define PREFIX as "\\sdcc"
12306 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12307 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12310 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12311 - Rewrote the register banking algorithm.
12312 - Added pCode live-range analysis to registers (for now, only non-used and
12313 singly-used registers optimized away)
12315 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12317 * 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.

12342 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12344 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12346 2002-03-28 Johan Knol <johan AT balder>
12348 * src/SDCCval.c: fixed bug #532436
12350 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12352 Added "char *Processor" field to the port structure.
12355 Added -p option. Allows port dependent processor to be specified.
12358 Initialized the new field char *Processor field to NULL in all ports
12361 Compiler generated registers for interrupt context saving
12362 were not getting allocated.
12364 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12367 Fixed left shift. Will promote the left side of a left shift
12368 if a) left shifting more than size of operand or b) when assigned
12369 to something size > size of left side
12371 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12373 tons of changes. Register allocation has been
12374 rewritten. Added customization for the various PICs. Flow
12375 analysis is restructured. ...
12377 * src/pic/device.h:
12380 * src/pic/device.c:
12381 Added. device.c is a PIC port hack to accomodate variations
12384 2002-03-13 Michael Hope <michaelh AT vroom>
12386 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12388 2002-03-04 johanknol <johanknol AT manik>
12390 * /src/SDCCval.c: fixed
12392 const unsigned char arr[][2] = { { 0, 1 } };
12393 t18.c:1: error: Initializer element is not constant
12395 2002-03-04 bela <bela AT manik>
