2214 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2216 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2217 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2219 One basic decision: e.g. src/clean.mk includes further files. In order
2220 to make this work there are two solutions:
2221 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2222 run configure on them. This way they can use
2223 'include $(srcdir)/port-clean.mk'
2224 - always include clean.mk by the Makefile at the same level. To avoid
2225 that `make clean` tries to include and build Makefile.dep the
2226 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2227 implemented, because now even `make uninstall` doesn't create
2228 Makefile.in. clean.mk could be eliminated by pasting it in
2231 * debugger/mcs51/Makefile.in: build own objects from library sources
2232 (SLIB, SDCC) in current directory
2234 * configure, configure.in: renamed --disable-device-lib-build in
2235 --disable-device-lib; added --enable-doc, the required tools are
2236 searched by configure; added result message; the toolchain for the
2237 belonging ports are now only built, if the port is enabled.
2239 * support/regression/*: all output is written in directory gen, because
2240 the fwk and ports directories don't livet in the build tree using vpath
2242 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2243 --disable-device-lib, added --enable-doc, added section VPATH
2245 * sim/ucsim/configure.in,
2246 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2247 z80 are enabled by default
2249 2006-04-24 Raphael Neider <rneider AT web.de>
2251 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2252 to config word, "pic14_"-prefixed some extern functions
2253 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2254 config word has been found
2255 * src/pic/device.h: added prototypes
2256 * src/pic/pcode.c: added "pic14_"-prefix where needed
2257 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2259 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2269 2006-04-24 Raphael Neider <rneider AT web.de>
2271 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2272 registers that have not been assigned proper liveranges,
2273 fixes #1469504 and #1474602,
2274 (pCodeRegOptimizeRegUsage): fixed typo in comment
2276 2006-04-24 Borut Razem <borut.razem AT siol.net>
2278 * device/examples/main8051.c: deleted - it was removed from CVS
2279 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2280 after the transition to Subversion

2542 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2544 * src/.version: increased version number to 2.5.5
2545 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2546 linking is done manually in pic16 port's _linkEdit,
2547 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2548 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2549 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2550 allocate asmop as AOP_ACC,

2564 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2565 call to allocReg, not by manually allocating a new one,
2566 (pic16_assignRegisters): now before going through the register
2567 allocating functions mark all registers as free. This eliminates some
2568 side effects resulting from peephole parser done earlier in the backbone
2570 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2617 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
2618 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2620 2006-03-06 Borut Razem <borut.razem AT siol.net>
2622 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2623 made the linker quiet
2625 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2627 * src/pic16/gen.c (genPcall): fixed bug #1443644
2628 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2629 which dumps before the function entry point a data byte which represents
2630 the number of the local variables used by the specified function, added
2631 'xinst' for initial support for Extended Instruction Support,
2632 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2633 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2634 port->fun_prefix anymore (may change later),
2635 (genFunction, genEndFunction): do not store/restore local registers for
2636 _main (this should take care the --main-return command line option in
2638 (genOr): removed some legacy pic-port instructions,
2639 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2640 performing operations with SFR's causes data to be written more than
2641 once to each SFR. Perhaps SFRs should be handled in special cases...
2642 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2644 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2647 --extended or -y for Extended Instruction Support,
2648 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2649 (deassignLRs): *** perhaps the most important change, old 'for' code
2650 (commented out for reference), didn't account for some registers which
2651 were left marked 'not free' after a pointer operation. The change
2652 reduces register usage a lot in some cases

4925 * src/SDCCglobal.h (struct options),
4927 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4928 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4929 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4930 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4931 always available in leading double underscore form. The C99 support is
4932 mostly missing, but it's a start.
4933 * support/regression/tests/bug-227710.c: fixed nonconforming use of

5012 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5014 * device/lib/printf_large.c: removed inline assembly for portability and
5015 readability. Use printf_fast if speed or size are more important.
5016 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5017 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5019 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5021 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5022 prevent compiler warning
5024 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5026 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5027 moved to level 0 and declared as static. Also they are explicit
5028 placed in access bank. This was necessery because some times they
5029 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5030 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5031 optimizations. Currently only compare to unsigned char is implemented,
5032 * src/pic16/gen.c: added fReturnIdx array,
5033 * (struct resolvedIfx) is moved to gen.h and made public,
5034 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5035 * (aopForSym): added an optimization to directly store in stack of
5036 the operand of a SEND iCode,
5037 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5038 but as registers instead (AOP_REG) using the fReturnIdx array,
5039 * (pic16_freeAsmop): remove the freed register from the
5040 _G.sregsAlloc field,
5041 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5042 a compare of 'WREG',
5043 * (pic16_popGetTempRegCond): changed function prototype, now
5044 function takes also a bitVector argument v which holds the current
5045 set of registers that are allocated for stack access by aopForSym,
5046 registers allocated in aopForSym for accessing stack symbols are not
5047 any more part of the functions usedRegs field,
5048 * (genCall): some times aopOp is called for a stack variable to be
5049 send, aopForSym might perform the push, if this is true make sure
5050 that genCall doesn't push the variable twice by testing _G.resDirect,
5051 * (genFunction): changed testing for unspecified interrupt number
5052 from 256 to INTNO_UNSPEC,
5053 * modified selection scheme of frame pointer generation. Previously
5054 if function did use local registers a frame pointer was generated,
5055 now a frame pointer is generated only if function has arguments
5056 (that need PLUSW2 register access), or has stack arguments, or the
5057 compiler is not instructed to omit the frame pointer,
5058 * (genEndFunction): before restoring local registers that were saved
5059 in the function preamble, also restore the registers that *might*
5060 have been allocated for stack access,
5061 * (genRet): removed some old comments,
5062 * (genCmp, the active (RN's) version): added a call to the
5063 pic16_genCmp_special function to perform the compare with a more
5064 robust and optimized way,
5065 * (genInline): a feature has been added in inline code generation,
5066 which allows a wildcard variable substitution when writing inline
5067 assembly. Code is incomplete and experimental therefore undocumented,
5068 * (genCast): changed order of aopOp for result and right to allow
5069 aopForSym to directly load the result if possible,
5070 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5071 perform an optimized compare on some selected special occasions,
5072 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5073 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5074 generate an IVT any more,
5075 * src/pic16/main.c (pic16_optionsTable): added command line option
5077 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5078 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5080 * src/pic16/NOTES: Raphael Neider added in list of active developers
5081 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5082 jumptable_end to prevent bug #,
5083 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5084 inCond and outCond fields,
5085 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5086 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5087 turn off register spilling,
5088 * (packRegsForOneUse): synced with other ports' versions although it
5089 is not used currently,
5090 * (pic16_packRegisters): added an optimization while reading
5091 structure bitfields, some registers may be saved (malloc code is
5092 decreased by 80 bytes)
5094 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5096 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5097 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5098 this can be optimized more?
5100 2005-03-10 Raphael Neider <rneider AT web.de>
5102 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5103 genNearPointerGet): (hopefully) fixed access to bitfields via
5104 pointers (p->bitN = x; and x = p->bitN; failed)
5106 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5108 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

5738 Adding support for replacing ljmps with sjmps in jumptables
5739 generated for switch statements. For now you need to set the
5740 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5741 Now 4 algorithms for mcs51 jumptable generation are used:
5742 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5743 addresses loaded pc-relative for up to 112 cases and stack-pushing
5744 target addresses loaded with offset from dptr for up to 256 cases.

5771 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5772 to call when a stack overflow occurs,
5773 * (malloc.h): added CVS Id tag,
5774 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5776 * added libc directory. The current version of LibC contains string
5777 functions, ctype functions and macros and some functions of the
5778 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5779 be extensively tested in the future. Standard disclaimer here.
5780 Library is not automatically build yet. But one can build it by
5781 invoking 'make' inside the libc directory.
5782 * added ADC library under libio. Preliminary version yet.

5791 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5792 * (pic16_storeForReturn): optimized return of 0,
5793 * (genCmp): experimental code for new genCmp which uses PIC18's
5794 special compare&skip instructions. Initial tests fail some times
5795 with variables grater than 1 byte in size, so new code is disabled,
5796 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5798 * (genCast): began a fix to optimize the casting of a bit to another
5799 bit, now assigning a bitfield to another bitfield will fail, sorry,
5800 * src/pic16/main.c: disabled the use of lr-support feature,
5801 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5804 bits with offset (case PO_GPR_BIT),
5805 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5807 * (isBankInstruction): modified to return 0 for no banking instruction,
5808 and 1 for banking instruction,
5809 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5810 caused stop processing pCodes after a inline assembly block,
5811 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5812 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5813 registers when it shouldn't,
5814 * src/pic16/ralloc.c (allocReg): add preliminary support for
5815 supporting a limited set of temporary registers,
5817 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5819 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5820 genDataPointerSet): ensure assignments always copy in MSB to LSB
5822 (loadRegFromAop): recognize CLRH optimization,
5823 (genFunction): optimize RECEIVE iCodes in reentrant functions
5825 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5827 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8825 loaded with the linker search paths (-L arguments) and the libraries
8826 to be linked with the current source (-l arguments). Changes
8827 currently will affect only the pic16 port.
8828 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8829 include path the port specific paths and port specific libraries,
8830 * gplink command now contains the $3 argument,
8831 * src/pic16/device.h,

8848 Documenting changes from previous commits.
8849 * configure.in (version 1.56),
8850 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8851 when generating output files to configure the pic16 library,
8852 but now I've commented it out, since gputils aren't installed in the
8853 SF compile farm, so library won't compile
8855 * device/lib/Makefile.in (version 1.56): initially I've added in
8856 target 'all' the prerequestive 'model-pic16' so it compiled the
8857 pic16 library, but now I've commented it out for the same reasons
8859 * added targets 'model-pic16' and 'objects-pic16' to compile the
8861 * added target 'port-specific-objects-pic16' to handle the
8862 generated libraries and copy them into the build/ directory
8863 * added target 'clean-intermediate-pic16' to clean intermediate
8864 files into pic16 directory
8865 * in target 'installdirs' added line to create directory pic16 in

8869 added lines to copy all header files to installation path,
8870 * in target 'installdirs' added line create directory for pic16
8871 headers in the installation path

9148 * device/include/Makefile.in: don't install CVS directories
9149 * device/lib/Makefile.in: added removal of CVS directories after install
9150 * doc/Makefile: fixed install, added local_icons
9151 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9152 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9153 * src/ds390/gen.c (genRightShift): fixed bug #870788
9154 * src/SDCCast.c (decorateType): fixed bug #870781
9156 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9158 PIC16 port related changes:
9159 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9160 added variable stackPos,
9162 * gen.c: genCall, assignResultValue: added support for
9163 pushing/retrieving function parameters to/from stack,
9164 genFunction,genEndFunction: setup stack frame for the
9166 genAddrOf: will be changed according to bug 863624
9168 * added files genutils.c and genutils.h which contain gen*
9169 debugged and optimised functions extracted from gen.c
9171 * glue.c: added variable 'externs' which holds extern symbols,
9172 pic16emitRegularMap: is modified to properly handle relocatable
9173 symbols under the new scheme,
9174 pic16createInterruptVect: is modified
9175 pic16printPublics: is modified to emit 'global' assembler directives,
9176 added pic16_printExterns to print extern symbols,
9177 pic16glue: initializes stack/frame pointer in the beginning of
9178 the assembly output. Temporary hack, will be corrected later,
9179 because gplink yet does not support stack and SDCC does not
9180 yet support a type of crt0.o object to create the final binary.
9182 * Removed many lines that contain 8051 legacy code.
9183 * The code is finally placed under a 'code' directive.
9184 * Added port specific options.
9186 * _process_pragma: simplified since now we do not need *special*
9187 include file to define SFR registers. But a separate header
9188 will be needed. This will be developed later.
9189 * _pic16_parseOptions: added, parses port specific options:
9190 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9191 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9192 --preplace-udata-with=
9194 * _pic16_setDefaultOptions: modified to initialize section names,
9195 but hack is temporarly out of order since it needs improvement.
9196 * _pic16_genAssemblerPreamble: configuration words are emitted by
9197 their address instead of their name. This part is incomplete and
9198 supports only the 18Fxx2 devices. Other devices will emit an error
9199 during assembly since they do not contain the same set of config
9201 * _pic16_genIVT: is modified,
9203 * pcode.c: added definitions for some hardware registers that are needed
9205 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9206 All PCI entries are updated. Now LFSR is supported.
9207 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9208 * added pic16_newpCodeOpLit2 to support instructions with
9209 two literal arguments
9210 * pic16_pCode2str: corrected code that emits assembler instructions
9211 with two literal operands and those that have an access bit modifier
9212 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9213 this fixes a bug which caused some labels to be lost, when an
9214 assembler directive was added, i.e. banksel,
9215 * pic16_FixRegisterBanking: improved logic that causes the insertion
9217 * InlineFunction: functions that are called once, are not any more
9218 inlined. This can be a port option in the future,
9220 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9222 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9223 hold the corresponding uninitialized symbols,
9224 * pic16_allocProcessorRegister: registers have explicit marked the
9226 * pic16_allocInternalRegister: registers are explicit marked as
9228 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9229 processing list, so bit registers were lost,
9232 * ralloc.h: added field 'accessBank' and original symbol operand
9233 in register definition,
9234 * removed the field isMapped from register definition,
9236 ** Several functions have been removed from various sources:
9237 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9238 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9239 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9240 pic16_assignRelocatableRegisters
9242 ** others have been introduced:
9243 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9244 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9246 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9248 * support/scripts/inc2h.pl: changed definition of BIT_AT
9249 to emit 'sbit at' instead of 'bit at'. This was a request.
9251 PIC16 port related preliminary changes:
9252 * gen.c: prefixed function popRegFromString with
9253 pic16_ and all references to it corrected
9254 * pcode.c: all pic16_pc_* hardware registers prefixed
9255 with underscore (_),
9256 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9257 * ralloc.c: newReg(): when register is REG_SFR then
9258 set address to rIdx,
9259 pic16_allocProcessorRegister(): marks register wasUsed=0
9260 pic16_writeUsedRegs(): added a call to assign processor
9261 registers via pic16_assignFixedRegisters
9263 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9265 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9266 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9267 variables in unused register banks. Also the SSEG is placed
9268 wherever there is enough space for it, and IDATA can be anywhere
9269 in internal RAM. For now compile using -Wl-Y[stack_size].
9270 The mem file is different for this option as well, since it
9271 makes no sense of talking about DSEG lenght.
9273 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9275 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9276 in certain cases, e.g. when ROM assignment, patch provided
9277 from Albert den Haan.

9518 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9520 * src/SDCCast.c (decorateType): disabled a transformation I added in
9521 revision 1.188 (access to fields of a structure at an absolute address);
9522 it breaks with bitfields, extern declarations, and gcse analysis.
9523 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9524 could be assigned through a pointer, so don't complain.
9525 * src/SDCCast.c (astErrors),
9527 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10125 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10126 of const struct should be treated as if const themselves)
10128 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10130 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10145 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10146 and restore of EA so that stack offsets to parameters are
10147 correct when using both critical and reentrant/stack-auto.

10162 * src/SDCCsymt.c (sclsFromPtr),
10164 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10165 support for standard C idiom of memory mapped variables; for
10166 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10167 to xdata int at 0x1234 tempvar = 1.
10168 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10185 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10187 Fixed bug #621531 (const & volatile confusion in the type chain).
10188 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10189 refer to the const or volatile state of the pointer itself.

10254 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10255 pcoderegs.h, ralloc.c, ralloc.h
10256 * main.c: added top header and GPL license notice
10257 * pcode.c: fixed the if-conditional warning
10259 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10261 * device/lib/_mullong.c: replaced int by short for gcc
10263 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10265 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10266 and JUMPTABLE iCodes properly now (worked by accident before)
10267 * src/mcs51/gen.c (leftRightUseAcc),
10268 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10269 iCode properly now. Use getSize instead of nRegs since a & b
10270 aren't part of the nRegs tally.
10272 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10274 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10280 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10281 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10282 fetching of the pointer
10283 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10284 copied from genNearPointerSet()
10285 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10286 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10287 If they pop r0/r1 they must be called in the opposite order than aopOp().
10288 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10289 (resp. --stack-auto), prepared for --xstack
10291 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10293 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10295 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10297 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10298 these ports have their own __sdcc_external_start()
10300 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10302 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10303 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10304 type for bits was changed. It resulted in bit variables becoming
10305 global, which is not permitted in PIC 14 assembly output.
10307 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10309 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10311 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10313 Z80 and MCS51 linkers complaint if a public symbol is defined
10314 in more than one library module:

10320 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10322 A few small changes that speed up the peephole optimizer.
10326 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10328 Try to make the peephole optimizer smarter by maintaining
10329 an association between the assembly source code and the
10330 iCodes that originated them. Put this information to use
10331 with a new peephole rule condition "notVolatile" so that
10332 the rules can be aggressive yet still safe.
10337 * src/mcs51/peeph.def
10339 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10343 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10344 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10345 if the left or right operand symbols have the accuse flag set.
10347 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10349 Changed the type of the result of the ! (NOT) operator to char;
10350 previously it returned the same type as the source. This allows
10351 us to eliminate all the genFloatNot functions (all of its target
10352 implementations were very buggy) since !float can use the same
10355 * src/SDCCicode.c (ast2iCode): ! returns char

10364 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10365 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10366 during interrupts. Ensure WSAVE is located at a shared bank address.
10367 2. Fixed page selection in some places
10368 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10369 the registers name strings.
10370 4. Fixed "signed / unsigned compare" compiler warnings.
10371 5. The PIC port manages its own allocation of the general purpose
10372 registers, but makes no attempt to reuse them. As a result when
10373 compiling it soon runs out of general purpose registers. Some
10374 additional code was added to the files pcode.c and device.c to walk
10375 through the function call tree and rename the registers so that they
10385 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10386 genPlus() & genMinus() when the result is the same as left or right
10388 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10392 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10394 Made bitfield a distinct type from bit so that bitfields
10395 convert as per ANSI C and bits retain their traditional
10396 boolean style behaviour. Implemented bitfield support in
10404 * src/ds390/gen.c: bit v bitfield split
10405 * src/z80/gen.c: New support for bitfields
10406 * support/regression/tests/bitfields.c: reenabled z80,
10409 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10411 Rules 246.x, 247.x relate to bitfields, the others speed up
10412 access to xdata mapped I/O devices.
10414 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10416 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10418 Cleaned up genPackBits and genUnpackBits and added two helper
10419 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10420 for literal assignments in genPackBits (thanks to Frieder for
10426 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10428 Fixed bug #748310 (pointer to function type mishandled when the
10429 function name is omitted). Also fixed a SIGSEGV when a function
10430 attribute (reentrant, etc) is used on a non-function or on a
10431 function but misplaced before the parameter list.
10433 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10435 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10436 * support/Util/SDCCerr.h,
10437 * support/Util/SDCCerr.c: Added func attr misuse error msg
10439 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10441 Fixed bug #787649 by anonymous
10442 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10443 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10445 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10447 Fixed numerous bitfield problems.
10449 * src/SDCC.y: More bitfield related error checking

10458 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10460 Made the constant following the "interrupt" keyword optional. If
10461 omitted, the function will not automatically be given an entry
10462 in the interrupt vector table (similar to #pragma NOIV, but
10463 less syntacticly kludgy). The interrupt number is also now
10464 range checked. Also fixed a bug in the high order bit example

10472 * support/Util/SDCCerr.h
10475 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10478 * src/SDCCicode.c (operandOperation): rewritten some ops
10479 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10480 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10482 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10483 be re-activated by defining REDUCE_LITERALS)
10484 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10485 unsigned, but are signed by default
10486 * src/SDCCval.c (constVal): rearranged
10487 * src/SDCCval.c (valMod): preliminary fix
10488 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10528 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10529 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10530 constants are unsigned; added recognition of "u" flag for unsigned
10531 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10532 * src/SDCCval.c (valDiv, valMod): fixed signdness
10533 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10534 signedness of modulo, left and right shift

10995 messages from optionsTable when a port is not configured, added
10996 support for the PIc16 port in the ports table, when executing
10997 the compiler with no port specified on command line, a default
10998 port is selected with the new macro DEFAULT_PORT which is
10999 defined in port.h, in setDefaultOptions() linkOptions is removed
11000 from initialization assignment, since now it is a set,
11001 parseCmdLine uses setParseWithComma for linkOptions, in
11002 linkEdit() linkOptions are accessed with new function indexSet()
11003 which returns the i'th item of a set variable. See SDCCset.c, in
11004 linkEdit() when calling buildCmdLine(), added linkOptions as
11005 last argument. Now users can pass arguments to gplink via the
11006 -Wl option, main() uses pic16glue() to glue up pic16 programs

11020 gpasm complaining and test the linkage with gplink, _linkCmd and
11021 _asmCmd changed to be more gplink and gpasm friendly
11022 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11023 produced an error when parsed, peep rule 12 is added to utilize
11024 movff, but it is commented out since the pCode does not support
11025 yet a command with 2 address arguments

12088 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12090 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12092 * in /sdcc/as/mcs51/ changed these files in order to create an
12093 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12094 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12095 following files to include the previous two files: aslink.dsp,
12096 Makefile.aslink, Makefile.bcc, and Makefile.in.
12098 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12099 .adb instead of .cdb
12101 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12103 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12104 value from option --iram-size.
12106 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12108 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12111 2002-09-18 <wiml AT hhhh.org>
12113 * SDCClrange.h: exposed setFromRange() and setToRange()
12114 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12115 packRegsForAccUse() (bug 542397)
12116 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12117 multiple times and emitting the fetch operations more than once
12118 added aopGetUsesAcc() function to allow binary operators to
12119 fetch their operands in the correct order; made genMinus() emit
12120 compact code for X = LITERAL - Y
12122 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12123 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12124 sprintf() in line 1267.
12126 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12127 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12130 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12131 Changes to aslink (All the changes are marked with 'JCF'):
12133 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12136 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12137 area BSEG. Also moves, if possible, the DATA area down into the internal
12138 ram so more space is available.
12140 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12143 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12144 not bytes. Function summary() which creates a memory usage summary
12145 file with extension .mem. Reports of overlaping stack and small stack
12146 size. If the space for the stack is less than 16 bytes aslink trows a
12149 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12150 the 8051. Option 'y' for memory summary output file.
12152 Changes to sdcc (All the changes are marked with 'JCF'):
12154 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12156 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12157 overlaying area for it (uses RegBankUsed[4]).
12159 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12160 bank zero as used by default. By default aslink locates the stack
12161 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12162 the creation of the .mem file. Delegates the allocation of data area
12163 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12164 the begining of the stack area to aslink.
12166 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12167 glue() in SDCCglue.c creates an area for it.
12169 2002-09-03 Borut Razem <borut.razem AT siol.net>
12170 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12171 sdcc/src/pic/glue.c:
12172 introduced atexit() handler for teporay files removal in case of
12173 errors, assertions, ...
12175 2002-08-29 Borut Razem <borut.razem AT siol.net>
12176 * sdcc/support/cpp2/auto-host_vc_in.h:
12177 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12178 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12179 Maybe there is a similar problem with BORLANDC? It should be checked!
12181 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12182 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12183 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12184 was not executed, and the compiler (cl) launched a warning:
12185 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12187 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12188 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12190 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12191 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12193 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12194 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12195 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12196 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12197 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12198 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12199 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12200 - added Release configuration in VS projects
12201 - review of compiler an linker options
12202 - VC .exe files are generated in bin_vc directory, not to interfere
12203 with binaries generated from other projects (cygwin, mingw, bcc ...)
12205 * sdcc/src/yacc.dsp: added
12207 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12208 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12209 and insert the version number definitions from .version
12211 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12213 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12214 added - genarate auto-host.h using auto-host_vc_in.h as template
12217 removed from CVS, generated automatically
12219 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12220 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12222 2002-08-11 Borut Razem <borut.razem AT siol.net>
12223 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12225 2002-08-10 Borut Razem <borut.razem AT siol.net>
12226 * src/SDCCmain.c (main):
12227 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12228 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12229 The consequence was that some temporary files were not removed.
12232 unification of code in functions tempfilename() and tempfile():
12233 function tempnam() is defined in Visual Studio 6.0 and .NET
12235 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12237 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12238 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12239 - removed compiler command line option /WX: Treats all warnings as errors
12240 - update a list of source files, included into the project
12242 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12243 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12244 changed project type to Generic Project so that can be correcly converted to VS.NET project
12246 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12248 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12250 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12252 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12253 added return 0 statements after assert() to make compiler happy
12255 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12256 added newline in the def file to keep MSC compiler satisfied
12258 * sdcc/src/z80/gen.c:
12259 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12260 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12261 - solved MSC error in function aopDump()
12263 * sdcc_vc.h: define PREFIX as "\\sdcc"
12265 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12266 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12269 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12270 - Rewrote the register banking algorithm.
12271 - Added pCode live-range analysis to registers (for now, only non-used and
12272 singly-used registers optimized away)
12274 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12276 * 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.

12305 2002-03-28 Johan Knol <johan AT balder>
12307 * src/SDCCval.c: fixed bug #532436
12309 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12311 Added "char *Processor" field to the port structure.
12314 Added -p option. Allows port dependent processor to be specified.
12317 Initialized the new field char *Processor field to NULL in all ports
12320 Compiler generated registers for interrupt context saving
12321 were not getting allocated.
12323 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12326 Fixed left shift. Will promote the left side of a left shift
12327 if a) left shifting more than size of operand or b) when assigned
12328 to something size > size of left side
12330 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12332 tons of changes. Register allocation has been
12333 rewritten. Added customization for the various PICs. Flow
12334 analysis is restructured. ...
12336 * src/pic/device.h:
12339 * src/pic/device.c:
12340 Added. device.c is a PIC port hack to accomodate variations
12343 2002-03-13 Michael Hope <michaelh AT vroom>
12345 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12347 2002-03-04 johanknol <johanknol AT manik>
12349 * /src/SDCCval.c: fixed
12351 const unsigned char arr[][2] = { { 0, 1 } };

12440 * sdcc/src/SDCCloop.c:
12441 Previous fix was not good. basic blocks that have "break" or "return" are
12442 not really partof a loop , but live ranges used in these blocks should
12443 be live thru the entire loop, so set partOfLoop but don't add them to
