2251 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2253 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2254 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2256 One basic decision: e.g. src/clean.mk includes further files. In order
2257 to make this work there are two solutions:
2258 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2259 run configure on them. This way they can use
2260 'include $(srcdir)/port-clean.mk'
2261 - always include clean.mk by the Makefile at the same level. To avoid
2262 that `make clean` tries to include and build Makefile.dep the
2263 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2264 implemented, because now even `make uninstall` doesn't create
2265 Makefile.in. clean.mk could be eliminated by pasting it in
2268 * debugger/mcs51/Makefile.in: build own objects from library sources
2269 (SLIB, SDCC) in current directory
2271 * configure, configure.in: renamed --disable-device-lib-build in
2272 --disable-device-lib; added --enable-doc, the required tools are
2273 searched by configure; added result message; the toolchain for the
2274 belonging ports are now only built, if the port is enabled.
2276 * support/regression/*: all output is written in directory gen, because
2277 the fwk and ports directories don't livet in the build tree using vpath
2279 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2280 --disable-device-lib, added --enable-doc, added section VPATH
2282 * sim/ucsim/configure.in,
2283 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2284 z80 are enabled by default
2286 2006-04-24 Raphael Neider <rneider AT web.de>
2288 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2289 to config word, "pic14_"-prefixed some extern functions
2290 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2291 config word has been found
2292 * src/pic/device.h: added prototypes
2293 * src/pic/pcode.c: added "pic14_"-prefix where needed

2308 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2309 registers that have not been assigned proper liveranges,
2310 fixes #1469504 and #1474602,
2311 (pCodeRegOptimizeRegUsage): fixed typo in comment

2315 * device/examples/main8051.c: deleted - it was removed from CVS

2604 allocating functions mark all registers as free. This eliminates some
2605 side effects resulting from peephole parser done earlier in the backbone

2655 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2657 2006-03-06 Borut Razem <borut.razem AT siol.net>
2659 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2660 made the linker quiet
2662 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2664 * src/pic16/gen.c (genPcall): fixed bug #1443644
2665 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2666 which dumps before the function entry point a data byte which represents
2667 the number of the local variables used by the specified function, added
2668 'xinst' for initial support for Extended Instruction Support,
2669 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2670 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2671 port->fun_prefix anymore (may change later),
2672 (genFunction, genEndFunction): do not store/restore local registers for
2673 _main (this should take care the --main-return command line option in
2675 (genOr): removed some legacy pic-port instructions,
2676 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2677 performing operations with SFR's causes data to be written more than
2678 once to each SFR. Perhaps SFRs should be handled in special cases...
2679 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

2686 (deassignLRs): *** perhaps the most important change, old 'for' code
2687 (commented out for reference), didn't account for some registers which
2688 were left marked 'not free' after a pointer operation. The change
2689 reduces register usage a lot in some cases

5047 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5049 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5051 * device/lib/printf_large.c: removed inline assembly for portability and
5052 readability. Use printf_fast if speed or size are more important.
5053 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5054 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5056 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5058 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5059 prevent compiler warning
5061 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5063 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5064 moved to level 0 and declared as static. Also they are explicit
5065 placed in access bank. This was necessery because some times they
5066 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5067 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5068 optimizations. Currently only compare to unsigned char is implemented,
5069 * src/pic16/gen.c: added fReturnIdx array,
5070 * (struct resolvedIfx) is moved to gen.h and made public,
5071 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5072 * (aopForSym): added an optimization to directly store in stack of
5073 the operand of a SEND iCode,
5074 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5075 but as registers instead (AOP_REG) using the fReturnIdx array,
5076 * (pic16_freeAsmop): remove the freed register from the
5077 _G.sregsAlloc field,
5078 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5079 a compare of 'WREG',
5080 * (pic16_popGetTempRegCond): changed function prototype, now
5081 function takes also a bitVector argument v which holds the current
5082 set of registers that are allocated for stack access by aopForSym,
5083 registers allocated in aopForSym for accessing stack symbols are not
5084 any more part of the functions usedRegs field,
5085 * (genCall): some times aopOp is called for a stack variable to be
5086 send, aopForSym might perform the push, if this is true make sure
5087 that genCall doesn't push the variable twice by testing _G.resDirect,
5088 * (genFunction): changed testing for unspecified interrupt number
5089 from 256 to INTNO_UNSPEC,
5090 * modified selection scheme of frame pointer generation. Previously
5091 if function did use local registers a frame pointer was generated,
5092 now a frame pointer is generated only if function has arguments
5093 (that need PLUSW2 register access), or has stack arguments, or the
5094 compiler is not instructed to omit the frame pointer,
5095 * (genEndFunction): before restoring local registers that were saved
5096 in the function preamble, also restore the registers that *might*
5097 have been allocated for stack access,
5098 * (genRet): removed some old comments,
5099 * (genCmp, the active (RN's) version): added a call to the
5100 pic16_genCmp_special function to perform the compare with a more
5101 robust and optimized way,
5102 * (genInline): a feature has been added in inline code generation,
5103 which allows a wildcard variable substitution when writing inline
5104 assembly. Code is incomplete and experimental therefore undocumented,
5105 * (genCast): changed order of aopOp for result and right to allow
5106 aopForSym to directly load the result if possible,
5107 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5108 perform an optimized compare on some selected special occasions,
5109 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5110 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5111 generate an IVT any more,
5112 * src/pic16/main.c (pic16_optionsTable): added command line option
5114 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5115 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5117 * src/pic16/NOTES: Raphael Neider added in list of active developers
5118 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5119 jumptable_end to prevent bug #,
5120 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5121 inCond and outCond fields,
5122 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5123 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5124 turn off register spilling,
5125 * (packRegsForOneUse): synced with other ports' versions although it
5126 is not used currently,
5127 * (pic16_packRegisters): added an optimization while reading
5128 structure bitfields, some registers may be saved (malloc code is
5129 decreased by 80 bytes)

5775 Adding support for replacing ljmps with sjmps in jumptables
5776 generated for switch statements. For now you need to set the
5777 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5778 Now 4 algorithms for mcs51 jumptable generation are used:
5779 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5780 addresses loaded pc-relative for up to 112 cases and stack-pushing
5781 target addresses loaded with offset from dptr for up to 256 cases.

5811 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5813 * added libc directory. The current version of LibC contains string
5814 functions, ctype functions and macros and some functions of the
5815 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5816 be extensively tested in the future. Standard disclaimer here.
5817 Library is not automatically build yet. But one can build it by
5818 invoking 'make' inside the libc directory.

5829 * (pic16_storeForReturn): optimized return of 0,
5830 * (genCmp): experimental code for new genCmp which uses PIC18's
5831 special compare&skip instructions. Initial tests fail some times
5832 with variables grater than 1 byte in size, so new code is disabled,
5833 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5835 * (genCast): began a fix to optimize the casting of a bit to another
5836 bit, now assigning a bitfield to another bitfield will fail, sorry,

5845 and 1 for banking instruction,
5846 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5847 caused stop processing pCodes after a inline assembly block,
5848 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5850 registers when it shouldn't,
5851 * src/pic16/ralloc.c (allocReg): add preliminary support for
5852 supporting a limited set of temporary registers,
5854 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5860 (genFunction): optimize RECEIVE iCodes in reentrant functions
5862 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8862 loaded with the linker search paths (-L arguments) and the libraries
8863 to be linked with the current source (-l arguments). Changes
8864 currently will affect only the pic16 port.
8865 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8866 include path the port specific paths and port specific libraries,
8867 * gplink command now contains the $3 argument,
8868 * src/pic16/device.h,

8885 Documenting changes from previous commits.
8886 * configure.in (version 1.56),
8887 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8888 when generating output files to configure the pic16 library,
8889 but now I've commented it out, since gputils aren't installed in the
8890 SF compile farm, so library won't compile
8892 * device/lib/Makefile.in (version 1.56): initially I've added in
8893 target 'all' the prerequestive 'model-pic16' so it compiled the
8894 pic16 library, but now I've commented it out for the same reasons
8896 * added targets 'model-pic16' and 'objects-pic16' to compile the
8898 * added target 'port-specific-objects-pic16' to handle the
8899 generated libraries and copy them into the build/ directory
8900 * added target 'clean-intermediate-pic16' to clean intermediate
8901 files into pic16 directory
8902 * in target 'installdirs' added line to create directory pic16 in

8906 added lines to copy all header files to installation path,
8907 * in target 'installdirs' added line create directory for pic16
8908 headers in the installation path

9139 * as/mcs51/lkmain.c: Help about -Y option
9140 * as/mcs51/lkarea.c: Fixed gcc warnings
9142 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9144 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
9146 * support/valdiag/tests/overflow.c: added
9147 * src/SDCCast.c (decorateType),
9148 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9149 LEFT_OP (left shift)
9151 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9153 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9154 (default behaviour).
9156 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9158 A python script to validate compiler diagnostic messages. It can be
9159 used to verify that sdcc complains about bad c source code and
9160 gives a good location of the error.
9161 * support/valdiag/Makefile,
9162 * support/valdiag/valdiag.py,
9163 * support/valdiag/tests/*
9165 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9167 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9168 * src/SDCCsymt.c (newEnumType),
9170 * support/Util/SDCCerr.c,
9171 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9173 * support/regression/tests/enum.c: added test for enum values that
9174 require at least 2 bytes of storage.
9176 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9178 * src/common.h: added ifndef/define/endif macros
9179 around the header file.
9180 Bug reported from Jesus Calvino-Fraga
9182 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9184 * sdcc.spec: updated
9185 * device/include/Makefile.in: don't install CVS directories
9186 * device/lib/Makefile.in: added removal of CVS directories after install
9187 * doc/Makefile: fixed install, added local_icons
9188 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9189 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9190 * src/ds390/gen.c (genRightShift): fixed bug #870788
9191 * src/SDCCast.c (decorateType): fixed bug #870781
9193 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9195 PIC16 port related changes:
9196 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9197 added variable stackPos,
9199 * gen.c: genCall, assignResultValue: added support for
9200 pushing/retrieving function parameters to/from stack,
9201 genFunction,genEndFunction: setup stack frame for the
9203 genAddrOf: will be changed according to bug 863624
9205 * added files genutils.c and genutils.h which contain gen*
9206 debugged and optimised functions extracted from gen.c
9208 * glue.c: added variable 'externs' which holds extern symbols,
9209 pic16emitRegularMap: is modified to properly handle relocatable
9210 symbols under the new scheme,
9211 pic16createInterruptVect: is modified
9212 pic16printPublics: is modified to emit 'global' assembler directives,
9213 added pic16_printExterns to print extern symbols,
9214 pic16glue: initializes stack/frame pointer in the beginning of
9215 the assembly output. Temporary hack, will be corrected later,
9216 because gplink yet does not support stack and SDCC does not
9217 yet support a type of crt0.o object to create the final binary.
9219 * Removed many lines that contain 8051 legacy code.
9220 * The code is finally placed under a 'code' directive.
9221 * Added port specific options.
9223 * _process_pragma: simplified since now we do not need *special*
9224 include file to define SFR registers. But a separate header
9225 will be needed. This will be developed later.
9226 * _pic16_parseOptions: added, parses port specific options:
9227 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9228 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9229 --preplace-udata-with=
9231 * _pic16_setDefaultOptions: modified to initialize section names,
9232 but hack is temporarly out of order since it needs improvement.
9233 * _pic16_genAssemblerPreamble: configuration words are emitted by
9234 their address instead of their name. This part is incomplete and
9235 supports only the 18Fxx2 devices. Other devices will emit an error
9236 during assembly since they do not contain the same set of config
9238 * _pic16_genIVT: is modified,
9240 * pcode.c: added definitions for some hardware registers that are needed
9242 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9243 All PCI entries are updated. Now LFSR is supported.
9244 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9245 * added pic16_newpCodeOpLit2 to support instructions with
9246 two literal arguments
9247 * pic16_pCode2str: corrected code that emits assembler instructions
9248 with two literal operands and those that have an access bit modifier
9249 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9250 this fixes a bug which caused some labels to be lost, when an
9251 assembler directive was added, i.e. banksel,
9252 * pic16_FixRegisterBanking: improved logic that causes the insertion
9254 * InlineFunction: functions that are called once, are not any more
9255 inlined. This can be a port option in the future,
9257 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9259 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9260 hold the corresponding uninitialized symbols,
9261 * pic16_allocProcessorRegister: registers have explicit marked the
9263 * pic16_allocInternalRegister: registers are explicit marked as
9265 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9266 processing list, so bit registers were lost,
9269 * ralloc.h: added field 'accessBank' and original symbol operand
9270 in register definition,
9271 * removed the field isMapped from register definition,
9273 ** Several functions have been removed from various sources:
9274 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9275 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9276 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9277 pic16_assignRelocatableRegisters
9279 ** others have been introduced:
9280 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9281 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9283 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9285 * support/scripts/inc2h.pl: changed definition of BIT_AT
9286 to emit 'sbit at' instead of 'bit at'. This was a request.
9288 PIC16 port related preliminary changes:
9289 * gen.c: prefixed function popRegFromString with
9290 pic16_ and all references to it corrected
9291 * pcode.c: all pic16_pc_* hardware registers prefixed
9292 with underscore (_),
9293 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9294 * ralloc.c: newReg(): when register is REG_SFR then
9295 set address to rIdx,
9296 pic16_allocProcessorRegister(): marks register wasUsed=0
9297 pic16_writeUsedRegs(): added a call to assign processor
9298 registers via pic16_assignFixedRegisters
9300 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9302 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9303 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9304 variables in unused register banks. Also the SSEG is placed
9305 wherever there is enough space for it, and IDATA can be anywhere
9306 in internal RAM. For now compile using -Wl-Y[stack_size].
9307 The mem file is different for this option as well, since it
9308 makes no sense of talking about DSEG lenght.
9310 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9312 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9313 in certain cases, e.g. when ROM assignment, patch provided
9314 from Albert den Haan.
9316 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9459 * src/mcs51/peephole.def,
9460 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9472 multiply defined with mismatching "at" address.
9474 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9476 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
9477 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

9555 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9557 * src/SDCCast.c (decorateType): disabled a transformation I added in
9558 revision 1.188 (access to fields of a structure at an absolute address);
9559 it breaks with bitfields, extern declarations, and gcse analysis.
9560 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9561 could be assigned through a pointer, so don't complain.
9562 * src/SDCCast.c (astErrors),
9564 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10144 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10145 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10146 (ralloc doesn't intentionally do this now, but perhaps later)
10147 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10148 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some
10149 register positioning bugs (Fixed bug #762602 and #795325)

10160 2003-09-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10162 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10163 of const struct should be treated as if const themselves)
10165 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10167 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10182 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10183 and restore of EA so that stack offsets to parameters are
10184 correct when using both critical and reentrant/stack-auto.

10186 size (can be triggered in error if sloc is shared between
10187 different sized objects)
10188 * device/include/float.h: fixed macros to explicitly use
10189 unsigned long where needed
10191 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10199 * src/SDCCsymt.c (sclsFromPtr),
10201 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10202 support for standard C idiom of memory mapped variables; for
10203 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10204 to xdata int at 0x1234 tempvar = 1.
10205 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
10206 provided by Akiya ISHIDA

10222 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10224 Fixed bug #621531 (const & volatile confusion in the type chain).
10225 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10226 refer to the const or volatile state of the pointer itself.
10238 * src/pic16/ralloc.c
10239 * support/regression/tests/const.c
10241 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10243 When checking for duplicated modules, use absolute paths
10244 instead of relative paths. Files changed:

10291 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10292 pcoderegs.h, ralloc.c, ralloc.h
10293 * main.c: added top header and GPL license notice

10296 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10298 * device/lib/_mullong.c: replaced int by short for gcc
10300 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10302 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10303 and JUMPTABLE iCodes properly now (worked by accident before)
10304 * src/mcs51/gen.c (leftRightUseAcc),
10305 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10306 iCode properly now. Use getSize instead of nRegs since a & b
10307 aren't part of the nRegs tally.
10309 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10311 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10315 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10317 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10318 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10319 fetching of the pointer
10320 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10321 copied from genNearPointerSet()
10322 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10323 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10324 If they pop r0/r1 they must be called in the opposite order than aopOp().
10325 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10326 (resp. --stack-auto), prepared for --xstack
10328 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10330 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10332 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10334 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10335 these ports have their own __sdcc_external_start()
10337 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10339 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10340 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10341 type for bits was changed. It resulted in bit variables becoming
10342 global, which is not permitted in PIC 14 assembly output.
10344 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10346 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10348 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10350 Z80 and MCS51 linkers complaint if a public symbol is defined
10351 in more than one library module:

10357 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10359 A few small changes that speed up the peephole optimizer.
10363 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10365 Try to make the peephole optimizer smarter by maintaining
10366 an association between the assembly source code and the
10367 iCodes that originated them. Put this information to use
10368 with a new peephole rule condition "notVolatile" so that
10369 the rules can be aggressive yet still safe.
10374 * src/mcs51/peeph.def
10376 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10380 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10381 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10382 if the left or right operand symbols have the accuse flag set.
10384 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10386 Changed the type of the result of the ! (NOT) operator to char;
10387 previously it returned the same type as the source. This allows
10388 us to eliminate all the genFloatNot functions (all of its target
10389 implementations were very buggy) since !float can use the same
10392 * src/SDCCicode.c (ast2iCode): ! returns char
10393 * src/mcs51/gen.c (genNot, genNotFloat),
10394 * src/ds390/gen.c (genNot, genNotFloat),
10395 * src/z80/gen.c (genNot, genNotFloat),
10396 * src/pic/gen.c (genNot, genNotFloat),
10397 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10401 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10402 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10403 during interrupts. Ensure WSAVE is located at a shared bank address.
10404 2. Fixed page selection in some places
10405 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10406 the registers name strings.
10407 4. Fixed "signed / unsigned compare" compiler warnings.
10408 5. The PIC port manages its own allocation of the general purpose
10409 registers, but makes no attempt to reuse them. As a result when
10410 compiling it soon runs out of general purpose registers. Some
10411 additional code was added to the files pcode.c and device.c to walk
10412 through the function call tree and rename the registers so that they
10422 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10423 genPlus() & genMinus() when the result is the same as left or right
10425 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10427 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
10429 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10431 Made bitfield a distinct type from bit so that bitfields
10432 convert as per ANSI C and bits retain their traditional
10433 boolean style behaviour. Implemented bitfield support in
10441 * src/ds390/gen.c: bit v bitfield split
10442 * src/z80/gen.c: New support for bitfields
10443 * support/regression/tests/bitfields.c: reenabled z80,
10446 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10448 Rules 246.x, 247.x relate to bitfields, the others speed up
10449 access to xdata mapped I/O devices.
10451 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10453 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10455 Cleaned up genPackBits and genUnpackBits and added two helper
10456 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10457 for literal assignments in genPackBits (thanks to Frieder for
10463 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10465 Fixed bug #748310 (pointer to function type mishandled when the
10466 function name is omitted). Also fixed a SIGSEGV when a function
10467 attribute (reentrant, etc) is used on a non-function or on a
10468 function but misplaced before the parameter list.
10470 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10472 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10473 * support/Util/SDCCerr.h,
10474 * support/Util/SDCCerr.c: Added func attr misuse error msg
10476 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10478 Fixed bug #787649 by anonymous
10479 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10480 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10482 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10484 Fixed numerous bitfield problems.
10486 * src/SDCC.y: More bitfield related error checking

10492 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10493 * support/regression/tests/bitfields.c: tests added
10495 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10497 Made the constant following the "interrupt" keyword optional. If
10498 omitted, the function will not automatically be given an entry
10499 in the interrupt vector table (similar to #pragma NOIV, but
10500 less syntacticly kludgy). The interrupt number is also now
10501 range checked. Also fixed a bug in the high order bit example

10509 * support/Util/SDCCerr.h
10512 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10515 * src/SDCCicode.c (operandOperation): rewritten some ops
10516 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10517 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10519 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10520 be re-activated by defining REDUCE_LITERALS)
10521 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10522 unsigned, but are signed by default
10523 * src/SDCCval.c (constVal): rearranged
10524 * src/SDCCval.c (valMod): preliminary fix
10525 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10563 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
10565 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10566 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10567 constants are unsigned; added recognition of "u" flag for unsigned
10568 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10569 * src/SDCCval.c (valDiv, valMod): fixed signdness
10570 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10571 signedness of modulo, left and right shift

10614 * support/librarian/configure.in
10615 * support/librarian/config_in.h

10626 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
10628 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
10629 there, while the mantissa of a double is "only" 53 bits wide.
10631 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11033 support for the PIc16 port in the ports table, when executing
11034 the compiler with no port specified on command line, a default
11035 port is selected with the new macro DEFAULT_PORT which is
11036 defined in port.h, in setDefaultOptions() linkOptions is removed
11037 from initialization assignment, since now it is a set,
11038 parseCmdLine uses setParseWithComma for linkOptions, in
11039 linkEdit() linkOptions are accessed with new function indexSet()
11040 which returns the i'th item of a set variable. See SDCCset.c, in
11041 linkEdit() when calling buildCmdLine(), added linkOptions as
11042 last argument. Now users can pass arguments to gplink via the

11057 gpasm complaining and test the linkage with gplink, _linkCmd and
11058 _asmCmd changed to be more gplink and gpasm friendly
11059 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11060 produced an error when parsed, peep rule 12 is added to utilize
11061 movff, but it is commented out since the pCode does not support
11062 yet a command with 2 address arguments

12114 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12115 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12124 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12125 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12127 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12129 * in /sdcc/as/mcs51/ changed these files in order to create an
12130 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12131 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12132 following files to include the previous two files: aslink.dsp,
12133 Makefile.aslink, Makefile.bcc, and Makefile.in.
12135 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12136 .adb instead of .cdb
12138 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12140 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12141 value from option --iram-size.
12143 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12145 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12148 2002-09-18 <wiml AT hhhh.org>
12150 * SDCClrange.h: exposed setFromRange() and setToRange()
12151 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12152 packRegsForAccUse() (bug 542397)
12153 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12154 multiple times and emitting the fetch operations more than once
12155 added aopGetUsesAcc() function to allow binary operators to
12156 fetch their operands in the correct order; made genMinus() emit
12157 compact code for X = LITERAL - Y
12159 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12160 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12161 sprintf() in line 1267.
12163 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12164 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12167 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12168 Changes to aslink (All the changes are marked with 'JCF'):
12170 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12173 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12174 area BSEG. Also moves, if possible, the DATA area down into the internal
12175 ram so more space is available.
12177 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12180 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12181 not bytes. Function summary() which creates a memory usage summary
12182 file with extension .mem. Reports of overlaping stack and small stack
12183 size. If the space for the stack is less than 16 bytes aslink trows a
12186 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12187 the 8051. Option 'y' for memory summary output file.
12189 Changes to sdcc (All the changes are marked with 'JCF'):
12191 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12193 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12194 overlaying area for it (uses RegBankUsed[4]).
12196 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12197 bank zero as used by default. By default aslink locates the stack
12198 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12199 the creation of the .mem file. Delegates the allocation of data area
12200 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12201 the begining of the stack area to aslink.
12203 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12204 glue() in SDCCglue.c creates an area for it.
12206 2002-09-03 Borut Razem <borut.razem AT siol.net>
12207 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12208 sdcc/src/pic/glue.c:
12209 introduced atexit() handler for teporay files removal in case of
12210 errors, assertions, ...
12212 2002-08-29 Borut Razem <borut.razem AT siol.net>
12213 * sdcc/support/cpp2/auto-host_vc_in.h:
12214 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12215 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12216 Maybe there is a similar problem with BORLANDC? It should be checked!
12218 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12219 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12220 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12221 was not executed, and the compiler (cl) launched a warning:
12222 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12224 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12225 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12227 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12228 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12230 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12231 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12232 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12233 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12234 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12235 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12236 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12237 - added Release configuration in VS projects
12238 - review of compiler an linker options
12239 - VC .exe files are generated in bin_vc directory, not to interfere
12240 with binaries generated from other projects (cygwin, mingw, bcc ...)
12242 * sdcc/src/yacc.dsp: added
12244 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12245 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12246 and insert the version number definitions from .version
12248 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12250 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12251 added - genarate auto-host.h using auto-host_vc_in.h as template
12254 removed from CVS, generated automatically
12256 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12257 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12259 2002-08-11 Borut Razem <borut.razem AT siol.net>
12260 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12262 2002-08-10 Borut Razem <borut.razem AT siol.net>
12263 * src/SDCCmain.c (main):
12264 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12265 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12266 The consequence was that some temporary files were not removed.
12269 unification of code in functions tempfilename() and tempfile():
12270 function tempnam() is defined in Visual Studio 6.0 and .NET
12272 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12274 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12275 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12276 - removed compiler command line option /WX: Treats all warnings as errors
12277 - update a list of source files, included into the project
12279 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12280 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12281 changed project type to Generic Project so that can be correcly converted to VS.NET project
12283 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12285 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12287 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12289 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12290 added return 0 statements after assert() to make compiler happy
12292 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12293 added newline in the def file to keep MSC compiler satisfied
12295 * sdcc/src/z80/gen.c:
12296 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12297 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12298 - solved MSC error in function aopDump()
12300 * sdcc_vc.h: define PREFIX as "\\sdcc"
12302 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12303 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12306 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12307 - Rewrote the register banking algorithm.
12308 - Added pCode live-range analysis to registers (for now, only non-used and
12309 singly-used registers optimized away)
12311 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12313 * 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.

12340 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12342 2002-03-28 Johan Knol <johan AT balder>
12344 * src/SDCCval.c: fixed bug #532436
12346 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12348 Added "char *Processor" field to the port structure.
12351 Added -p option. Allows port dependent processor to be specified.
12354 Initialized the new field char *Processor field to NULL in all ports
12357 Compiler generated registers for interrupt context saving
12358 were not getting allocated.
12360 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12363 Fixed left shift. Will promote the left side of a left shift
12364 if a) left shifting more than size of operand or b) when assigned
12365 to something size > size of left side
12367 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12369 tons of changes. Register allocation has been
12370 rewritten. Added customization for the various PICs. Flow
12371 analysis is restructured. ...
12373 * src/pic/device.h:
12376 * src/pic/device.c:
12377 Added. device.c is a PIC port hack to accomodate variations
12380 2002-03-13 Michael Hope <michaelh AT vroom>
12382 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12384 2002-03-04 johanknol <johanknol AT manik>
12386 * /src/SDCCval.c: fixed
12388 const unsigned char arr[][2] = { { 0, 1 } };
12389 t18.c:1: error: Initializer element is not constant
12391 2002-03-04 bela <bela AT manik>
