231 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
233 Enabled VPATH feature: changed nearly all Makefiles (149 files).
234 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
236 One basic decision: e.g. src/clean.mk includes further files. In order
237 to make this work there are two solutions:
238 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
239 run configure on them. This way they can use
240 'include $(srcdir)/port-clean.mk'
241 - always include clean.mk by the Makefile at the same level. To avoid
242 that `make clean` tries to include and build Makefile.dep the
243 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
244 implemented, because now even `make uninstall` doesn't create
245 Makefile.in. clean.mk could be eliminated by pasting it in
248 * debugger/mcs51/Makefile.in: build own objects from library sources
249 (SLIB, SDCC) in current directory
251 * configure, configure.in: renamed --disable-device-lib-build in
252 --disable-device-lib; added --enable-doc, the required tools are
253 searched by configure; added result message; the toolchain for the
254 belonging ports are now only built, if the port is enabled.
256 * support/regression/*: all output is written in directory gen, because
257 the fwk and ports directories don't livet in the build tree using vpath
259 * doc/sdccman.lyx: renamed --disable-device-lib-build to
260 --disable-device-lib, added --enable-doc, added section VPATH
262 * sim/ucsim/configure.in,
263 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
264 z80 are enabled by default
266 2006-04-24 Raphael Neider <rneider AT web.de>
268 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
269 to config word, "pic14_"-prefixed some extern functions
270 (pic14_emitConfigWord): emit __config directive(s) if assignment to
271 config word has been found
272 * src/pic/device.h: added prototypes
273 * src/pic/pcode.c: added "pic14_"-prefix where needed
274 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
276 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

279 (pic14createInterruptVect): moved generating __config directives away

536 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
537 implemented patch 1120823 Thanks to Willy De la Court (normal
538 interrupts need an interrupt number now if they are made critical),
539 and enabled nesting of critical functions though not for gbz80
540 (genCritical, genEndCritical): added functions
541 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
542 * src/z80/mappings.i: added "ei" to all mappings
544 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

547 submitted by the Debian SDCC maintainer Aurelien Jarno:
548 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
549 archive with gcc 4.1 on mips and wrote the patch"
551 2006-03-16 Raphael Neider <rneider AT web.de>
553 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
554 the left operand is shorter than the result (c* = lit-c* + int),
556 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
559 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
561 * src/.version: increased version number to 2.5.5
562 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
563 linking is done manually in pic16 port's _linkEdit,
564 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
565 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
566 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
567 allocate asmop as AOP_ACC,
568 (aopForRemat): added parameter 'bool result' in function declaration,
569 (pic16_aopGet): return AOP_ACC when accessing WREG,

574 calling function in absolute addresses,
575 (genAssign): take into account AOP_ACC asmop,
576 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
577 * src/pic16/pcoderegs.c: some debug functions and lines added,

579 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
581 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
582 call to allocReg, not by manually allocating a new one,
583 (pic16_assignRegisters): now before going through the register
584 allocating functions mark all registers as free. This eliminates some
585 side effects resulting from peephole parser done earlier in the backbone
587 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
589 * src/SDCCicode.c (geniCodeLogic),

608 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
609 (aopForSym, aopOp): increment asmop.allocated if reused,
610 (freeAsmop): decrement asmop.allocated and check for zero instead of
612 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
613 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

640 made the linker quiet
642 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
644 * src/pic16/gen.c (genPcall): fixed bug #1443644
645 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
646 which dumps before the function entry point a data byte which represents
647 the number of the local variables used by the specified function, added
648 'xinst' for initial support for Extended Instruction Support,
649 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
650 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
651 port->fun_prefix anymore (may change later),
652 (genFunction, genEndFunction): do not store/restore local registers for
653 _main (this should take care the --main-return command line option in
655 (genOr): removed some legacy pic-port instructions,
656 * src/pic16/genarith.c (genAddLit): re-enabled old code because
657 performing operations with SFR's causes data to be written more than
658 once to each SFR. Perhaps SFRs should be handled in special cases...
659 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
661 * src/pic16/main.c (_process_pragma): stack bound checking did not take
662 into account for stack starting position,
663 (struct OPTIONS pic16_optionsTable): added command line argument
664 --extended or -y for Extended Instruction Support,
665 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
666 (deassignLRs): *** perhaps the most important change, old 'for' code
667 (commented out for reference), didn't account for some registers which
668 were left marked 'not free' after a pointer operation. The change
669 reduces register usage a lot in some cases

3045 placed in access bank. This was necessery because some times they
3046 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3047 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3048 optimizations. Currently only compare to unsigned char is implemented,
3049 * src/pic16/gen.c: added fReturnIdx array,
3050 * (struct resolvedIfx) is moved to gen.h and made public,
3051 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3052 * (aopForSym): added an optimization to directly store in stack of
3053 the operand of a SEND iCode,
3054 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3055 but as registers instead (AOP_REG) using the fReturnIdx array,
3056 * (pic16_freeAsmop): remove the freed register from the
3057 _G.sregsAlloc field,
3058 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3059 a compare of 'WREG',
3060 * (pic16_popGetTempRegCond): changed function prototype, now
3061 function takes also a bitVector argument v which holds the current
3062 set of registers that are allocated for stack access by aopForSym,
3063 registers allocated in aopForSym for accessing stack symbols are not
3064 any more part of the functions usedRegs field,
3065 * (genCall): some times aopOp is called for a stack variable to be
3066 send, aopForSym might perform the push, if this is true make sure
3067 that genCall doesn't push the variable twice by testing _G.resDirect,
3068 * (genFunction): changed testing for unspecified interrupt number
3069 from 256 to INTNO_UNSPEC,
3070 * modified selection scheme of frame pointer generation. Previously
3071 if function did use local registers a frame pointer was generated,
3072 now a frame pointer is generated only if function has arguments
3073 (that need PLUSW2 register access), or has stack arguments, or the
3074 compiler is not instructed to omit the frame pointer,
3075 * (genEndFunction): before restoring local registers that were saved
3076 in the function preamble, also restore the registers that *might*
3077 have been allocated for stack access,
3078 * (genRet): removed some old comments,
3079 * (genCmp, the active (RN's) version): added a call to the
3080 pic16_genCmp_special function to perform the compare with a more
3081 robust and optimized way,
3082 * (genInline): a feature has been added in inline code generation,
3083 which allows a wildcard variable substitution when writing inline
3084 assembly. Code is incomplete and experimental therefore undocumented,
3085 * (genCast): changed order of aopOp for result and right to allow
3086 aopForSym to directly load the result if possible,
3087 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3088 perform an optimized compare on some selected special occasions,
3089 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3090 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3091 generate an IVT any more,
3092 * src/pic16/main.c (pic16_optionsTable): added command line option
3094 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3095 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3097 * src/pic16/NOTES: Raphael Neider added in list of active developers
3098 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3099 jumptable_end to prevent bug #,
3100 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3101 inCond and outCond fields,
3102 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3103 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3104 turn off register spilling,
3105 * (packRegsForOneUse): synced with other ports' versions although it
3106 is not used currently,
3107 * (pic16_packRegisters): added an optimization while reading
3108 structure bitfields, some registers may be saved (malloc code is
3109 decreased by 80 bytes)
3111 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3113 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3114 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3115 this can be optimized more?
3117 2005-03-10 Raphael Neider <rneider AT web.de>
3119 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3120 genNearPointerGet): (hopefully) fixed access to bitfields via

3447 access stack and frame pointers. They are initially assigned to
3448 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3449 accessing SFRs. Updated all occurences of modification of stack or
3450 frame pointer in gen.c and pcode.c,
3451 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3452 assigning of a literal value to pointers,

3755 Adding support for replacing ljmps with sjmps in jumptables
3756 generated for switch statements. For now you need to set the
3757 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3758 Now 4 algorithms for mcs51 jumptable generation are used:
3759 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3793 * added libc directory. The current version of LibC contains string
3794 functions, ctype functions and macros and some functions of the
3795 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3796 be extensively tested in the future. Standard disclaimer here.

3809 * (pic16_storeForReturn): optimized return of 0,
3810 * (genCmp): experimental code for new genCmp which uses PIC18's
3811 special compare&skip instructions. Initial tests fail some times
3812 with variables grater than 1 byte in size, so new code is disabled,
3813 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3815 * (genCast): began a fix to optimize the casting of a bit to another
3816 bit, now assigning a bitfield to another bitfield will fail, sorry,

3830 registers when it shouldn't,
3831 * src/pic16/ralloc.c (allocReg): add preliminary support for
3832 supporting a limited set of temporary registers,
3834 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6839 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6841 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6842 loaded with the linker search paths (-L arguments) and the libraries
6843 to be linked with the current source (-l arguments). Changes
6844 currently will affect only the pic16 port.
6845 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6846 include path the port specific paths and port specific libraries,
6847 * gplink command now contains the $3 argument,
6848 * src/pic16/device.h,
6849 * src/pic16/device.c,: structure PIC_device is made public and
6850 renamed to PIC16_device, the same for variable Pics which is renamed

6865 Documenting changes from previous commits.
6866 * configure.in (version 1.56),
6867 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6868 when generating output files to configure the pic16 library,
6869 but now I've commented it out, since gputils aren't installed in the
6870 SF compile farm, so library won't compile
6872 * device/lib/Makefile.in (version 1.56): initially I've added in
6873 target 'all' the prerequestive 'model-pic16' so it compiled the
6874 pic16 library, but now I've commented it out for the same reasons
6876 * added targets 'model-pic16' and 'objects-pic16' to compile the
6878 * added target 'port-specific-objects-pic16' to handle the
6879 generated libraries and copy them into the build/ directory
6880 * added target 'clean-intermediate-pic16' to clean intermediate
6881 files into pic16 directory
6882 * in target 'installdirs' added line to create directory pic16 in

6903 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6904 option so that it actually works. Made it specific to the z80, since
6905 the gbz80 doesn't have these kinds of I/O ports.
6907 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6909 * device/include/z180.h,

6933 via literal number. The symbol is placed in the corresponding
6934 position of the data ram
6935 * (pic16_dump_section): relocatable and absolute uninitialized
6936 data are now emitted in sorted order to reduce section naming,
6937 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6938 weren't marked as being in the access bank,
6940 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6942 Added portion of GNU PIC Library under the directory
6943 device/include/pic16 and device/lib/pic16. These files
6944 contain the declarations of SFRs for the PIC18Fxx2 devices.
6945 The directory is initialized via configure from toplevel.
6947 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6975 all over. Telling LaTeX to be less strict with word spacing
6976 to better keep the right margin. Changed some notes about
6977 maintainance of the ports in section 3.2.1 - is it OK like this?
6979 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6981 SDCC source changes:
6982 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
6983 convilong): modified to inform the pic16 port that builtin functions
6986 PIC16 PORT specific changes:
6987 * src/pic16/device.c pic16_dump_equates() added,
6988 processor registers declared internally by the port are emitted in
6989 the translation as equates,
6990 * src/pic16/gen.c: inline code is passed unprocessed to the
6992 * (pic16_popGetLit2): fnuction modified to take second operand as
6993 pCodeOp pointer and not as literal,

7016 UPPER for immediate operands,
7017 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7019 * src/pic16/peeph.def: all peepholes with movff are commented out,
7020 because there is a problem in the pcode peep optimizer,

7129 LEFT_OP (left shift)
7131 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7133 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7134 (default behaviour).
7136 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7138 A python script to validate compiler diagnostic messages. It can be
7139 used to verify that sdcc complains about bad c source code and
7140 gives a good location of the error.
7141 * support/valdiag/Makefile,
7142 * support/valdiag/valdiag.py,
7143 * support/valdiag/tests/*

7160 Bug reported from Jesus Calvino-Fraga
7162 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7164 * sdcc.spec: updated
7165 * device/include/Makefile.in: don't install CVS directories
7166 * device/lib/Makefile.in: added removal of CVS directories after install
7167 * doc/Makefile: fixed install, added local_icons
7168 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7169 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7170 * src/ds390/gen.c (genRightShift): fixed bug #870788
7171 * src/SDCCast.c (decorateType): fixed bug #870781
7173 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7175 PIC16 port related changes:
7176 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7177 added variable stackPos,
7179 * gen.c: genCall, assignResultValue: added support for
7180 pushing/retrieving function parameters to/from stack,
7181 genFunction,genEndFunction: setup stack frame for the
7183 genAddrOf: will be changed according to bug 863624
7185 * added files genutils.c and genutils.h which contain gen*
7186 debugged and optimised functions extracted from gen.c
7188 * glue.c: added variable 'externs' which holds extern symbols,
7189 pic16emitRegularMap: is modified to properly handle relocatable
7190 symbols under the new scheme,
7191 pic16createInterruptVect: is modified
7192 pic16printPublics: is modified to emit 'global' assembler directives,
7193 added pic16_printExterns to print extern symbols,
7194 pic16glue: initializes stack/frame pointer in the beginning of
7195 the assembly output. Temporary hack, will be corrected later,
7196 because gplink yet does not support stack and SDCC does not
7197 yet support a type of crt0.o object to create the final binary.
7199 * Removed many lines that contain 8051 legacy code.
7200 * The code is finally placed under a 'code' directive.
7201 * Added port specific options.
7203 * _process_pragma: simplified since now we do not need *special*
7204 include file to define SFR registers. But a separate header
7205 will be needed. This will be developed later.
7206 * _pic16_parseOptions: added, parses port specific options:
7207 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7208 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7209 --preplace-udata-with=
7211 * _pic16_setDefaultOptions: modified to initialize section names,
7212 but hack is temporarly out of order since it needs improvement.
7213 * _pic16_genAssemblerPreamble: configuration words are emitted by
7214 their address instead of their name. This part is incomplete and
7215 supports only the 18Fxx2 devices. Other devices will emit an error
7216 during assembly since they do not contain the same set of config
7218 * _pic16_genIVT: is modified,
7220 * pcode.c: added definitions for some hardware registers that are needed
7222 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7223 All PCI entries are updated. Now LFSR is supported.
7224 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7225 * added pic16_newpCodeOpLit2 to support instructions with
7226 two literal arguments
7227 * pic16_pCode2str: corrected code that emits assembler instructions
7228 with two literal operands and those that have an access bit modifier
7229 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7230 this fixes a bug which caused some labels to be lost, when an
7231 assembler directive was added, i.e. banksel,
7232 * pic16_FixRegisterBanking: improved logic that causes the insertion
7234 * InlineFunction: functions that are called once, are not any more
7235 inlined. This can be a port option in the future,
7237 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7239 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7240 hold the corresponding uninitialized symbols,
7241 * pic16_allocProcessorRegister: registers have explicit marked the
7243 * pic16_allocInternalRegister: registers are explicit marked as
7245 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7246 processing list, so bit registers were lost,
7249 * ralloc.h: added field 'accessBank' and original symbol operand
7250 in register definition,
7251 * removed the field isMapped from register definition,
7253 ** Several functions have been removed from various sources:
7254 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7255 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7256 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7257 pic16_assignRelocatableRegisters
7259 ** others have been introduced:
7260 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7261 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7263 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7265 * support/scripts/inc2h.pl: changed definition of BIT_AT
7266 to emit 'sbit at' instead of 'bit at'. This was a request.
7268 PIC16 port related preliminary changes:
7269 * gen.c: prefixed function popRegFromString with
7270 pic16_ and all references to it corrected
7271 * pcode.c: all pic16_pc_* hardware registers prefixed
7272 with underscore (_),
7273 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7274 * ralloc.c: newReg(): when register is REG_SFR then
7275 set address to rIdx,
7276 pic16_allocProcessorRegister(): marks register wasUsed=0
7277 pic16_writeUsedRegs(): added a call to assign processor
7278 registers via pic16_assignFixedRegisters
7280 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7282 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7283 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7284 variables in unused register banks. Also the SSEG is placed
7285 wherever there is enough space for it, and IDATA can be anywhere
7286 in internal RAM. For now compile using -Wl-Y[stack_size].
7287 The mem file is different for this option as well, since it
7288 makes no sense of talking about DSEG lenght.
7290 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7292 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7293 in certain cases, e.g. when ROM assignment, patch provided
7294 from Albert den Haan.
7296 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8298 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8299 fetching of the pointer
8300 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8301 copied from genNearPointerSet()
8302 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8303 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8319 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8320 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8321 type for bits was changed. It resulted in bit variables becoming
8322 global, which is not permitted in PIC 14 assembly output.
8324 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8326 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8339 A few small changes that speed up the peephole optimizer.
8343 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8345 Try to make the peephole optimizer smarter by maintaining
8346 an association between the assembly source code and the
8347 iCodes that originated them. Put this information to use
8348 with a new peephole rule condition "notVolatile" so that
8349 the rules can be aggressive yet still safe.
8354 * src/mcs51/peeph.def
8356 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8360 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8361 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8362 if the left or right operand symbols have the accuse flag set.
8364 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8366 Changed the type of the result of the ! (NOT) operator to char;
8367 previously it returned the same type as the source. This allows
8368 us to eliminate all the genFloatNot functions (all of its target
8369 implementations were very buggy) since !float can use the same
8372 * src/SDCCicode.c (ast2iCode): ! returns char

8381 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8382 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8383 during interrupts. Ensure WSAVE is located at a shared bank address.
8384 2. Fixed page selection in some places
8385 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8386 the registers name strings.
8387 4. Fixed "signed / unsigned compare" compiler warnings.
8388 5. The PIC port manages its own allocation of the general purpose
8389 registers, but makes no attempt to reuse them. As a result when
8390 compiling it soon runs out of general purpose registers. Some
8391 additional code was added to the files pcode.c and device.c to walk
8392 through the function call tree and rename the registers so that they
8402 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8403 genPlus() & genMinus() when the result is the same as left or right

8409 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8411 Made bitfield a distinct type from bit so that bitfields
8412 convert as per ANSI C and bits retain their traditional
8413 boolean style behaviour. Implemented bitfield support in
8421 * src/ds390/gen.c: bit v bitfield split
8422 * src/z80/gen.c: New support for bitfields
8423 * support/regression/tests/bitfields.c: reenabled z80,
8426 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8428 Rules 246.x, 247.x relate to bitfields, the others speed up
8429 access to xdata mapped I/O devices.
8431 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8433 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8435 Cleaned up genPackBits and genUnpackBits and added two helper
8436 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8437 for literal assignments in genPackBits (thanks to Frieder for
8443 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8445 Fixed bug #748310 (pointer to function type mishandled when the
8446 function name is omitted). Also fixed a SIGSEGV when a function
8447 attribute (reentrant, etc) is used on a non-function or on a
8448 function but misplaced before the parameter list.
8450 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8452 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8453 * support/Util/SDCCerr.h,

8475 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8477 Made the constant following the "interrupt" keyword optional. If
8478 omitted, the function will not automatically be given an entry
8479 in the interrupt vector table (similar to #pragma NOIV, but
8480 less syntacticly kludgy). The interrupt number is also now
8481 range checked. Also fixed a bug in the high order bit example

8502 unsigned, but are signed by default
8503 * src/SDCCval.c (constVal): rearranged
8504 * src/SDCCval.c (valMod): preliminary fix
8505 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9011 added if/endif conditional macros to remove options help
9012 messages from optionsTable when a port is not configured, added
9013 support for the PIc16 port in the ports table, when executing
9014 the compiler with no port specified on command line, a default
9015 port is selected with the new macro DEFAULT_PORT which is
9016 defined in port.h, in setDefaultOptions() linkOptions is removed
9017 from initialization assignment, since now it is a set,
9018 parseCmdLine uses setParseWithComma for linkOptions, in
9019 linkEdit() linkOptions are accessed with new function indexSet()
9020 which returns the i'th item of a set variable. See SDCCset.c, in
9021 linkEdit() when calling buildCmdLine(), added linkOptions as
9022 last argument. Now users can pass arguments to gplink via the
9023 -Wl option, main() uses pic16glue() to glue up pic16 programs

9037 gpasm complaining and test the linkage with gplink, _linkCmd and
9038 _asmCmd changed to be more gplink and gpasm friendly
9039 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9040 produced an error when parsed, peep rule 12 is added to utilize
9041 movff, but it is commented out since the pCode does not support
9042 yet a command with 2 address arguments
9044 2003-05-18 <johan AT balder>
9046 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9071 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9073 2003-05-11 Borut Razem <borut.razem AT siol.net>
9075 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10105 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10107 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10109 * in \sdcc\as\mcs51\ changed these files in order to create an
10110 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10111 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10112 following files to include the previous two files: aslink.dsp,
10113 Makefile.aslink, Makefile.bcc, and Makefile.in.
10115 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10116 .adb instead of .cdb
10118 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10120 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10121 value from option --iram-size.
10123 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10125 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10128 2002-09-18 <wiml AT hhhh.org>
10130 * SDCClrange.h: exposed setFromRange() and setToRange()
10131 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10132 packRegsForAccUse() (bug 542397)
10133 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10134 multiple times and emitting the fetch operations more than once
10135 added aopGetUsesAcc() function to allow binary operators to
10136 fetch their operands in the correct order; made genMinus() emit
10137 compact code for X = LITERAL - Y
10139 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10140 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10141 sprintf() in line 1267.
10143 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10144 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10147 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10148 Changes to aslink (All the changes are marked with 'JCF'):
10150 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10153 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10154 area BSEG. Also moves, if possible, the DATA area down into the internal
10155 ram so more space is available.
10157 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10160 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10161 not bytes. Function summary() which creates a memory usage summary
10162 file with extension .mem. Reports of overlaping stack and small stack
10163 size. If the space for the stack is less than 16 bytes aslink trows a
10166 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10167 the 8051. Option 'y' for memory summary output file.
10169 Changes to sdcc (All the changes are marked with 'JCF'):
10171 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10173 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10174 overlaying area for it (uses RegBankUsed[4]).
10176 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10177 bank zero as used by default. By default aslink locates the stack
10178 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10179 the creation of the .mem file. Delegates the allocation of data area
10180 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10181 the begining of the stack area to aslink.
10183 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10184 glue() in SDCCglue.c creates an area for it.
10186 2002-09-03 Borut Razem <borut.razem AT siol.net>
10187 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10188 sdcc/src/pic/glue.c:
10189 introduced atexit() handler for teporay files removal in case of
10190 errors, assertions, ...
10192 2002-08-29 Borut Razem <borut.razem AT siol.net>
10193 * sdcc/support/cpp2/auto-host_vc_in.h:
10194 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10195 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10196 Maybe there is a similar problem with BORLANDC? It should be checked!
10198 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10199 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10200 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10201 was not executed, and the compiler (cl) launched a warning:
10202 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10204 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10205 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10207 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10208 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10210 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10211 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10212 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10213 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10214 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10215 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10216 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10217 - added Release configuration in VS projects
10218 - review of compiler an linker options
10219 - VC .exe files are generated in bin_vc directory, not to interfere
10220 with binaries generated from other projects (cygwin, mingw, bcc ...)
10222 * sdcc/src/yacc.dsp: added
10224 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10225 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10226 and insert the version number definitions from .version
10228 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10230 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10231 added - genarate auto-host.h using auto-host_vc_in.h as template
10234 removed from CVS, generated automatically
10236 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10237 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10239 2002-08-11 Borut Razem <borut.razem AT siol.net>
10240 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10242 2002-08-10 Borut Razem <borut.razem AT siol.net>
10243 * src/SDCCmain.c (main):
10244 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10245 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10246 The consequence was that some temporary files were not removed.
10249 unification of code in functions tempfilename() and tempfile():
10250 function tempnam() is defined in Visual Studio 6.0 and .NET
10252 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10254 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10255 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10256 - removed compiler command line option /WX: Treats all warnings as errors
10257 - update a list of source files, included into the project
10259 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10260 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10261 changed project type to Generic Project so that can be correcly converted to VS.NET project
10263 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10265 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10267 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10269 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10270 added return 0 statements after assert() to make compiler happy
10272 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10273 added newline in the def file to keep MSC compiler satisfied
10275 * sdcc/src/z80/gen.c:
10276 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10277 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10278 - solved MSC error in function aopDump()
10280 * sdcc_vc.h: define PREFIX as "\\sdcc"
10282 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10283 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10286 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10287 - Rewrote the register banking algorithm.
10288 - Added pCode live-range analysis to registers (for now, only non-used and
10289 singly-used registers optimized away)
10291 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10293 * 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.

10322 2002-03-28 Johan Knol <johan AT balder>
10324 * src/SDCCval.c: fixed bug #532436
10326 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10328 Added "char *Processor" field to the port structure.
10331 Added -p option. Allows port dependent processor to be specified.
10334 Initialized the new field char *Processor field to NULL in all ports
10337 Compiler generated registers for interrupt context saving
10338 were not getting allocated.
10340 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10343 Fixed left shift. Will promote the left side of a left shift
10344 if a) left shifting more than size of operand or b) when assigned
10345 to something size > size of left side
10347 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10349 tons of changes. Register allocation has been
10350 rewritten. Added customization for the various PICs. Flow
10351 analysis is restructured. ...
10353 * src/pic/device.h:
10356 * src/pic/device.c:
10357 Added. device.c is a PIC port hack to accomodate variations
10360 2002-03-13 Michael Hope <michaelh AT vroom>
10362 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10364 2002-03-04 johanknol <johanknol AT manik>
10366 * /src/SDCCval.c: fixed
10368 const unsigned char arr[][2] = { { 0, 1 } };
10369 t18.c:1: error: Initializer element is not constant
