2541 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2543 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2544 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2546 One basic decision: e.g. src/clean.mk includes further files. In order
2547 to make this work there are two solutions:
2548 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2549 run configure on them. This way they can use
2550 'include $(srcdir)/port-clean.mk'
2551 - always include clean.mk by the Makefile at the same level. To avoid
2552 that `make clean` tries to include and build Makefile.dep the
2553 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2554 implemented, because now even `make uninstall` doesn't create
2555 Makefile.in. clean.mk could be eliminated by pasting it in
2558 * debugger/mcs51/Makefile.in: build own objects from library sources
2559 (SLIB, SDCC) in current directory
2561 * configure, configure.in: renamed --disable-device-lib-build in
2562 --disable-device-lib; added --enable-doc, the required tools are
2563 searched by configure; added result message; the toolchain for the
2564 belonging ports are now only built, if the port is enabled.
2566 * support/regression/*: all output is written in directory gen, because
2567 the fwk and ports directories don't livet in the build tree using vpath
2569 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2570 --disable-device-lib, added --enable-doc, added section VPATH
2572 * sim/ucsim/configure.in,
2573 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2574 z80 are enabled by default
2576 2006-04-24 Raphael Neider <rneider AT web.de>
2578 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2579 to config word, "pic14_"-prefixed some extern functions
2580 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2581 config word has been found
2582 * src/pic/device.h: added prototypes
2583 * src/pic/pcode.c: added "pic14_"-prefix where needed
2584 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2586 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2588 (pic14emitRegularMap): ignore config words,
2589 (pic14createInterruptVect): moved generating __config directives away
2590 (picglue): have __config directives emitted
2592 2006-04-24 Borut Razem <borut.razem AT siol.net>
2594 * doc/Makefile: sync with nightly build makefile
2596 2006-04-24 Raphael Neider <rneider AT web.de>
2598 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2599 registers that have not been assigned proper liveranges,
2600 fixes #1469504 and #1474602,
2601 (pCodeRegOptimizeRegUsage): fixed typo in comment
2603 2006-04-24 Borut Razem <borut.razem AT siol.net>

2848 interrupts need an interrupt number now if they are made critical),
2849 and enabled nesting of critical functions though not for gbz80
2850 (genCritical, genEndCritical): added functions
2851 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2852 * src/z80/mappings.i: added "ei" to all mappings

2864 the left operand is shorter than the result (c* = lit-c* + int),
2866 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2869 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2871 * src/.version: increased version number to 2.5.5
2872 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2873 linking is done manually in pic16 port's _linkEdit,
2874 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2875 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2876 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2877 allocate asmop as AOP_ACC,
2878 (aopForRemat): added parameter 'bool result' in function declaration,
2879 (pic16_aopGet): return AOP_ACC when accessing WREG,
2880 (pic16_popGetTempReg): minor modification,

2891 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2892 call to allocReg, not by manually allocating a new one,
2893 (pic16_assignRegisters): now before going through the register
2894 allocating functions mark all registers as free. This eliminates some
2895 side effects resulting from peephole parser done earlier in the backbone

2955 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2956 which dumps before the function entry point a data byte which represents
2957 the number of the local variables used by the specified function, added
2958 'xinst' for initial support for Extended Instruction Support,
2959 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2960 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2961 port->fun_prefix anymore (may change later),
2962 (genFunction, genEndFunction): do not store/restore local registers for
2963 _main (this should take care the --main-return command line option in
2965 (genOr): removed some legacy pic-port instructions,
2966 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2967 performing operations with SFR's causes data to be written more than
2968 once to each SFR. Perhaps SFRs should be handled in special cases...
2969 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2971 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2972 into account for stack starting position,

2976 (deassignLRs): *** perhaps the most important change, old 'for' code
2977 (commented out for reference), didn't account for some registers which
2978 were left marked 'not free' after a pointer operation. The change
2979 reduces register usage a lot in some cases
2981 2006-03-04 Borut Razem <borut.razem AT siol.net>

3015 (pic16_printIvalUnion,pic16_isUnion): NEW, handle initialized unions
3016 more correctly, fixes bug #1232186

5254 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5255 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5256 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5257 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5258 always available in leading double underscore form. The C99 support is
5259 mostly missing, but it's a start.
5260 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5261 reserved identifier "__data".
5263 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5339 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5341 * device/lib/printf_large.c: removed inline assembly for portability and
5342 readability. Use printf_fast if speed or size are more important.
5343 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5344 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5346 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5348 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5349 prevent compiler warning
5351 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5353 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5354 moved to level 0 and declared as static. Also they are explicit
5355 placed in access bank. This was necessery because some times they
5356 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5357 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5358 optimizations. Currently only compare to unsigned char is implemented,
5359 * src/pic16/gen.c: added fReturnIdx array,
5360 * (struct resolvedIfx) is moved to gen.h and made public,
5361 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5362 * (aopForSym): added an optimization to directly store in stack of
5363 the operand of a SEND iCode,
5364 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5365 but as registers instead (AOP_REG) using the fReturnIdx array,
5366 * (pic16_freeAsmop): remove the freed register from the
5367 _G.sregsAlloc field,
5368 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5369 a compare of 'WREG',
5370 * (pic16_popGetTempRegCond): changed function prototype, now
5371 function takes also a bitVector argument v which holds the current
5372 set of registers that are allocated for stack access by aopForSym,
5373 registers allocated in aopForSym for accessing stack symbols are not
5374 any more part of the functions usedRegs field,
5375 * (genCall): some times aopOp is called for a stack variable to be
5376 send, aopForSym might perform the push, if this is true make sure
5377 that genCall doesn't push the variable twice by testing _G.resDirect,
5378 * (genFunction): changed testing for unspecified interrupt number
5379 from 256 to INTNO_UNSPEC,
5380 * modified selection scheme of frame pointer generation. Previously
5381 if function did use local registers a frame pointer was generated,
5382 now a frame pointer is generated only if function has arguments
5383 (that need PLUSW2 register access), or has stack arguments, or the
5384 compiler is not instructed to omit the frame pointer,
5385 * (genEndFunction): before restoring local registers that were saved
5386 in the function preamble, also restore the registers that *might*
5387 have been allocated for stack access,
5388 * (genRet): removed some old comments,
5389 * (genCmp, the active (RN's) version): added a call to the
5390 pic16_genCmp_special function to perform the compare with a more
5391 robust and optimized way,
5392 * (genInline): a feature has been added in inline code generation,
5393 which allows a wildcard variable substitution when writing inline
5394 assembly. Code is incomplete and experimental therefore undocumented,
5395 * (genCast): changed order of aopOp for result and right to allow
5396 aopForSym to directly load the result if possible,
5397 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5398 perform an optimized compare on some selected special occasions,
5399 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5400 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5401 generate an IVT any more,
5402 * src/pic16/main.c (pic16_optionsTable): added command line option
5404 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5405 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5407 * src/pic16/NOTES: Raphael Neider added in list of active developers
5408 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5409 jumptable_end to prevent bug #,
5410 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5411 inCond and outCond fields,
5412 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5413 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5414 turn off register spilling,
5415 * (packRegsForOneUse): synced with other ports' versions although it
5416 is not used currently,
5417 * (pic16_packRegisters): added an optimization while reading
5418 structure bitfields, some registers may be saved (malloc code is
5419 decreased by 80 bytes)
5421 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5423 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5424 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5425 this can be optimized more?
5427 2005-03-10 Raphael Neider <rneider AT web.de>
5429 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5430 genNearPointerGet): (hopefully) fixed access to bitfields via
5431 pointers (p->bitN = x; and x = p->bitN; failed)
5433 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5477 to keep the correct label reference count when adding/removing references
5478 to labels. A peephole file using this is appended to patch #1144962.

6065 Adding support for replacing ljmps with sjmps in jumptables
6066 generated for switch statements. For now you need to set the
6067 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6068 Now 4 algorithms for mcs51 jumptable generation are used:
6069 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6070 addresses loaded pc-relative for up to 112 cases and stack-pushing
6071 target addresses loaded with offset from dptr for up to 256 cases.

6098 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6099 to call when a stack overflow occurs,
6100 * (malloc.h): added CVS Id tag,
6101 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6103 * added libc directory. The current version of LibC contains string
6104 functions, ctype functions and macros and some functions of the
6105 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6106 be extensively tested in the future. Standard disclaimer here.
6107 Library is not automatically build yet. But one can build it by
6108 invoking 'make' inside the libc directory.
6109 * added ADC library under libio. Preliminary version yet.
6111 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6118 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6119 * (pic16_storeForReturn): optimized return of 0,
6120 * (genCmp): experimental code for new genCmp which uses PIC18's
6121 special compare&skip instructions. Initial tests fail some times
6122 with variables grater than 1 byte in size, so new code is disabled,
6123 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6125 * (genCast): began a fix to optimize the casting of a bit to another
6126 bit, now assigning a bitfield to another bitfield will fail, sorry,
6127 * src/pic16/main.c: disabled the use of lr-support feature,
6128 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6131 bits with offset (case PO_GPR_BIT),
6132 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6134 * (isBankInstruction): modified to return 0 for no banking instruction,
6135 and 1 for banking instruction,
6136 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6137 caused stop processing pCodes after a inline assembly block,
6138 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6139 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6140 registers when it shouldn't,
6141 * src/pic16/ralloc.c (allocReg): add preliminary support for
6142 supporting a limited set of temporary registers,
6144 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6146 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6147 genDataPointerSet): ensure assignments always copy in MSB to LSB
6149 (loadRegFromAop): recognize CLRH optimization,
6150 (genFunction): optimize RECEIVE iCodes in reentrant functions
6152 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6154 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9081 * src/pic/glue (pic14emitRegularMap),
9082 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
9084 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
9086 * src/pic/pcode.c (PCodeID): commented out left over debug code
9088 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
9090 * support/valdiag/tests/overflow.c: added shift tests
9098 * src/pic/pcodepeep.c,
9099 * src/pic/pcoderegs.c,
9101 * src/pic/ralloc.h: applied patch from Slade Rich;
9102 added support for multiple code pages and multiple RAM banks on the
9103 PIC 14 port. The ASM files now no longer simply assume all the
9104 code / RAM are in the same page / bank. This means the linker can
9105 safely allocate code/RAM of separate ASM files to different pages/banks.
9106 * doc/sdccman.lyx: added Slade's tips
9107 * src/mcs51/peeph.def: fixed bug #880768

9116 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
9119 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9120 strtof is not part of C89 and isn't included with Mac OS X.
9122 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9124 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

9149 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9151 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9152 loaded with the linker search paths (-L arguments) and the libraries
9153 to be linked with the current source (-l arguments). Changes
9154 currently will affect only the pic16 port.
9155 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9156 include path the port specific paths and port specific libraries,
9157 * gplink command now contains the $3 argument,
9158 * src/pic16/device.h,
9159 * src/pic16/device.c,: structure PIC_device is made public and
9160 renamed to PIC16_device, the same for variable Pics which is renamed
9161 to Pics16. Updated all references to them.
9162 * src/pic16/glue.c (pic16glue): corrected bug with code
9163 initialization which bypassed the variable initializations block.
9165 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9166 COMPILE_FLAGS and added the --nostdinc option
9168 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9173 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9175 Documenting changes from previous commits.
9176 * configure.in (version 1.56),
9177 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9178 when generating output files to configure the pic16 library,
9179 but now I've commented it out, since gputils aren't installed in the
9180 SF compile farm, so library won't compile
9182 * device/lib/Makefile.in (version 1.56): initially I've added in
9183 target 'all' the prerequestive 'model-pic16' so it compiled the
9184 pic16 library, but now I've commented it out for the same reasons
9186 * added targets 'model-pic16' and 'objects-pic16' to compile the
9188 * added target 'port-specific-objects-pic16' to handle the
9189 generated libraries and copy them into the build/ directory
9190 * added target 'clean-intermediate-pic16' to clean intermediate
9191 files into pic16 directory
9192 * in target 'installdirs' added line to create directory pic16 in
9193 the installation path
9195 * device/include/Makefile.in (version 1.11): in target 'install'
9196 added lines to copy all header files to installation path,
9197 * in target 'installdirs' added line create directory for pic16
9198 headers in the installation path

9213 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9214 option so that it actually works. Made it specific to the z80, since
9215 the gbz80 doesn't have these kinds of I/O ports.
9217 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9219 * device/include/z180.h,

9241 Mainly changes to support compilation of the device libraries
9242 * src/pic16/device.c: stack is allocated via symbol and not
9243 via literal number. The symbol is placed in the corresponding
9244 position of the data ram
9245 * (pic16_dump_section): relocatable and absolute uninitialized
9246 data are now emitted in sorted order to reduce section naming,
9247 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9248 weren't marked as being in the access bank,
9250 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9252 Added portion of GNU PIC Library under the directory
9253 device/include/pic16 and device/lib/pic16. These files
9254 contain the declarations of SFRs for the PIC18Fxx2 devices.
9255 The directory is initialized via configure from toplevel.
9257 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9259 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

9285 all over. Telling LaTeX to be less strict with word spacing
9286 to better keep the right margin. Changed some notes about
9287 maintainance of the ports in section 3.2.1 - is it OK like this?
9289 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9327 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9329 * src/pic16/peeph.def: all peepholes with movff are commented out,
9330 because there is a problem in the pcode peep optimizer,
9331 * src/pic16/ralloc.c: the register allocator can now reuse local

9393 override default uninitialized data segment definition for
9394 devices only with SHAREBANK memory (reported from Erik Epetrich)
9395 * (pic14emitOverlay): modified to emit a commented overlay segment
9396 directive when no overlay data exist
9397 * (picglue): modified to emit uninitialized data segment
9398 according to udata_section_name

9451 * support/valdiag/Makefile,
9452 * support/valdiag/valdiag.py,
9453 * support/valdiag/tests/*

9470 Bug reported from Jesus Calvino-Fraga
9472 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9474 * sdcc.spec: updated
9475 * device/include/Makefile.in: don't install CVS directories

9483 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9485 PIC16 port related changes:
9486 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9487 added variable stackPos,
9489 * gen.c: genCall, assignResultValue: added support for
9490 pushing/retrieving function parameters to/from stack,
9491 genFunction,genEndFunction: setup stack frame for the
9493 genAddrOf: will be changed according to bug 863624
9495 * added files genutils.c and genutils.h which contain gen*
9496 debugged and optimised functions extracted from gen.c
9498 * glue.c: added variable 'externs' which holds extern symbols,
9499 pic16emitRegularMap: is modified to properly handle relocatable
9500 symbols under the new scheme,
9501 pic16createInterruptVect: is modified
9502 pic16printPublics: is modified to emit 'global' assembler directives,
9503 added pic16_printExterns to print extern symbols,
9504 pic16glue: initializes stack/frame pointer in the beginning of
9505 the assembly output. Temporary hack, will be corrected later,
9506 because gplink yet does not support stack and SDCC does not
9507 yet support a type of crt0.o object to create the final binary.
9509 * Removed many lines that contain 8051 legacy code.
9510 * The code is finally placed under a 'code' directive.
9511 * Added port specific options.
9513 * _process_pragma: simplified since now we do not need *special*
9514 include file to define SFR registers. But a separate header
9515 will be needed. This will be developed later.
9516 * _pic16_parseOptions: added, parses port specific options:
9517 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9518 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9519 --preplace-udata-with=
9521 * _pic16_setDefaultOptions: modified to initialize section names,
9522 but hack is temporarly out of order since it needs improvement.
9523 * _pic16_genAssemblerPreamble: configuration words are emitted by
9524 their address instead of their name. This part is incomplete and
9525 supports only the 18Fxx2 devices. Other devices will emit an error
9526 during assembly since they do not contain the same set of config
9528 * _pic16_genIVT: is modified,
9530 * pcode.c: added definitions for some hardware registers that are needed
9532 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9533 All PCI entries are updated. Now LFSR is supported.
9534 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9535 * added pic16_newpCodeOpLit2 to support instructions with
9536 two literal arguments
9537 * pic16_pCode2str: corrected code that emits assembler instructions
9538 with two literal operands and those that have an access bit modifier
9539 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9540 this fixes a bug which caused some labels to be lost, when an
9541 assembler directive was added, i.e. banksel,
9542 * pic16_FixRegisterBanking: improved logic that causes the insertion
9544 * InlineFunction: functions that are called once, are not any more
9545 inlined. This can be a port option in the future,
9547 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9549 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9550 hold the corresponding uninitialized symbols,
9551 * pic16_allocProcessorRegister: registers have explicit marked the
9553 * pic16_allocInternalRegister: registers are explicit marked as
9555 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9556 processing list, so bit registers were lost,
9559 * ralloc.h: added field 'accessBank' and original symbol operand
9560 in register definition,
9561 * removed the field isMapped from register definition,
9563 ** Several functions have been removed from various sources:
9564 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9565 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9566 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9567 pic16_assignRelocatableRegisters
9569 ** others have been introduced:
9570 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9571 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9573 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9575 * support/scripts/inc2h.pl: changed definition of BIT_AT
9576 to emit 'sbit at' instead of 'bit at'. This was a request.
9578 PIC16 port related preliminary changes:
9579 * gen.c: prefixed function popRegFromString with
9580 pic16_ and all references to it corrected
9581 * pcode.c: all pic16_pc_* hardware registers prefixed
9582 with underscore (_),
9583 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9584 * ralloc.c: newReg(): when register is REG_SFR then
9585 set address to rIdx,
9586 pic16_allocProcessorRegister(): marks register wasUsed=0
9587 pic16_writeUsedRegs(): added a call to assign processor
9588 registers via pic16_assignFixedRegisters
9590 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9592 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9593 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9594 variables in unused register banks. Also the SSEG is placed
9595 wherever there is enough space for it, and IDATA can be anywhere
9596 in internal RAM. For now compile using -Wl-Y[stack_size].
9597 The mem file is different for this option as well, since it
9598 makes no sense of talking about DSEG lenght.
9600 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9602 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9847 * src/SDCCast.c (decorateType): disabled a transformation I added in
9848 revision 1.188 (access to fields of a structure at an absolute address);
9849 it breaks with bitfields, extern declarations, and gcse analysis.
9850 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9851 could be assigned through a pointer, so don't complain.

10613 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10614 If they pop r0/r1 they must be called in the opposite order than aopOp().
10615 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10616 (resp. --stack-auto), prepared for --xstack

10629 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10630 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10631 type for bits was changed. It resulted in bit variables becoming
10632 global, which is not permitted in PIC 14 assembly output.
10634 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10636 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10638 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10640 Z80 and MCS51 linkers complaint if a public symbol is defined

10647 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10649 A few small changes that speed up the peephole optimizer.
10653 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10655 Try to make the peephole optimizer smarter by maintaining
10656 an association between the assembly source code and the
10657 iCodes that originated them. Put this information to use
10658 with a new peephole rule condition "notVolatile" so that
10659 the rules can be aggressive yet still safe.
10664 * src/mcs51/peeph.def
10666 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10670 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10671 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10672 if the left or right operand symbols have the accuse flag set.
10674 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10676 Changed the type of the result of the ! (NOT) operator to char;
10677 previously it returned the same type as the source. This allows
10678 us to eliminate all the genFloatNot functions (all of its target
10679 implementations were very buggy) since !float can use the same
10682 * src/SDCCicode.c (ast2iCode): ! returns char
10683 * src/mcs51/gen.c (genNot, genNotFloat),
10684 * src/ds390/gen.c (genNot, genNotFloat),
10685 * src/z80/gen.c (genNot, genNotFloat),
10686 * src/pic/gen.c (genNot, genNotFloat),

10691 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10692 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10693 during interrupts. Ensure WSAVE is located at a shared bank address.
10694 2. Fixed page selection in some places
10695 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10696 the registers name strings.
10697 4. Fixed "signed / unsigned compare" compiler warnings.
10698 5. The PIC port manages its own allocation of the general purpose
10699 registers, but makes no attempt to reuse them. As a result when
10700 compiling it soon runs out of general purpose registers. Some
10701 additional code was added to the files pcode.c and device.c to walk
10702 through the function call tree and rename the registers so that they
10712 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10713 genPlus() & genMinus() when the result is the same as left or right
10715 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10719 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10721 Made bitfield a distinct type from bit so that bitfields
10722 convert as per ANSI C and bits retain their traditional
10723 boolean style behaviour. Implemented bitfield support in
10731 * src/ds390/gen.c: bit v bitfield split
10732 * src/z80/gen.c: New support for bitfields
10733 * support/regression/tests/bitfields.c: reenabled z80,
10736 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10738 Rules 246.x, 247.x relate to bitfields, the others speed up
10739 access to xdata mapped I/O devices.
10741 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10743 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10745 Cleaned up genPackBits and genUnpackBits and added two helper
10746 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10747 for literal assignments in genPackBits (thanks to Frieder for
10753 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10755 Fixed bug #748310 (pointer to function type mishandled when the
10756 function name is omitted). Also fixed a SIGSEGV when a function
10757 attribute (reentrant, etc) is used on a non-function or on a
10758 function but misplaced before the parameter list.
10760 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10762 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10763 * support/Util/SDCCerr.h,
10764 * support/Util/SDCCerr.c: Added func attr misuse error msg
10766 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10768 Fixed bug #787649 by anonymous
10769 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10770 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10772 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10785 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10787 Made the constant following the "interrupt" keyword optional. If
10788 omitted, the function will not automatically be given an entry
10789 in the interrupt vector table (similar to #pragma NOIV, but
10790 less syntacticly kludgy). The interrupt number is also now
10791 range checked. Also fixed a bug in the high order bit example

10807 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10809 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10810 be re-activated by defining REDUCE_LITERALS)
10811 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10812 unsigned, but are signed by default
10813 * src/SDCCval.c (constVal): rearranged
10814 * src/SDCCval.c (valMod): preliminary fix

11268 the regression tests I'm not brave enough to enable 245.b, 245.c
11269 * doc/sdccman.lyx: added latex preamble for hyperref package.
11270 Using pdflatex this will give you a hyperlinked pdf file with

11321 added if/endif conditional macros to remove options help
11322 messages from optionsTable when a port is not configured, added
11323 support for the PIc16 port in the ports table, when executing
11324 the compiler with no port specified on command line, a default
11325 port is selected with the new macro DEFAULT_PORT which is
11326 defined in port.h, in setDefaultOptions() linkOptions is removed
11327 from initialization assignment, since now it is a set,
11328 parseCmdLine uses setParseWithComma for linkOptions, in
11329 linkEdit() linkOptions are accessed with new function indexSet()
11330 which returns the i'th item of a set variable. See SDCCset.c, in
11331 linkEdit() when calling buildCmdLine(), added linkOptions as
11332 last argument. Now users can pass arguments to gplink via the
11333 -Wl option, main() uses pic16glue() to glue up pic16 programs

11346 * src/pic16/main.c: __config directives are commented out to stop
11347 gpasm complaining and test the linkage with gplink, _linkCmd and
11348 _asmCmd changed to be more gplink and gpasm friendly
11349 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11350 produced an error when parsed, peep rule 12 is added to utilize
11351 movff, but it is commented out since the pCode does not support
11352 yet a command with 2 address arguments
11354 2003-05-18 <johan AT balder>
11356 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12382 * src/pic/pcode.c: outcommented unused variable to remove warnings
12383 * src/pic/ralloc.c: outcommented unused variable to remove warnings
12385 2003-01-06 <karl AT turbobit.com>
12386 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
12389 2003-01-06 <johan AT balder>
12391 * src/SDCCicode.c: fixed array add
12393 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12394 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12395 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12397 2003-01-04 <johan AT balder>
12399 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12401 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12402 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12404 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12405 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12406 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12408 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12409 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12411 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12412 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12414 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12415 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12417 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12419 * in /sdcc/as/mcs51/ changed these files in order to create an
12420 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12421 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12422 following files to include the previous two files: aslink.dsp,
12423 Makefile.aslink, Makefile.bcc, and Makefile.in.
12425 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12426 .adb instead of .cdb
12428 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12430 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12431 value from option --iram-size.
12433 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12435 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12438 2002-09-18 <wiml AT hhhh.org>
12440 * SDCClrange.h: exposed setFromRange() and setToRange()
12441 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12442 packRegsForAccUse() (bug 542397)
12443 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12444 multiple times and emitting the fetch operations more than once
12445 added aopGetUsesAcc() function to allow binary operators to
12446 fetch their operands in the correct order; made genMinus() emit
12447 compact code for X = LITERAL - Y
12449 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12450 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12451 sprintf() in line 1267.
12453 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12454 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12457 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12458 Changes to aslink (All the changes are marked with 'JCF'):
12460 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12463 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12464 area BSEG. Also moves, if possible, the DATA area down into the internal
12465 ram so more space is available.
12467 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12470 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12471 not bytes. Function summary() which creates a memory usage summary
12472 file with extension .mem. Reports of overlaping stack and small stack
12473 size. If the space for the stack is less than 16 bytes aslink trows a
12476 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12477 the 8051. Option 'y' for memory summary output file.
12479 Changes to sdcc (All the changes are marked with 'JCF'):
12481 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12483 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12484 overlaying area for it (uses RegBankUsed[4]).
12486 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12487 bank zero as used by default. By default aslink locates the stack
12488 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12489 the creation of the .mem file. Delegates the allocation of data area
12490 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12491 the begining of the stack area to aslink.
12493 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12494 glue() in SDCCglue.c creates an area for it.
12496 2002-09-03 Borut Razem <borut.razem AT siol.net>
12497 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12498 sdcc/src/pic/glue.c:
12499 introduced atexit() handler for teporay files removal in case of
12500 errors, assertions, ...
12502 2002-08-29 Borut Razem <borut.razem AT siol.net>
12503 * sdcc/support/cpp2/auto-host_vc_in.h:
12504 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12505 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12506 Maybe there is a similar problem with BORLANDC? It should be checked!
12508 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12509 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12510 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12511 was not executed, and the compiler (cl) launched a warning:
12512 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12514 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12515 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12517 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12518 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12520 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12521 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12522 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12523 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12524 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12525 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12526 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12527 - added Release configuration in VS projects
12528 - review of compiler an linker options
12529 - VC .exe files are generated in bin_vc directory, not to interfere
12530 with binaries generated from other projects (cygwin, mingw, bcc ...)
12532 * sdcc/src/yacc.dsp: added
12534 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12535 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12536 and insert the version number definitions from .version
12538 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12540 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12541 added - genarate auto-host.h using auto-host_vc_in.h as template
12544 removed from CVS, generated automatically
12546 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12547 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12549 2002-08-11 Borut Razem <borut.razem AT siol.net>
12550 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12552 2002-08-10 Borut Razem <borut.razem AT siol.net>
12553 * src/SDCCmain.c (main):
12554 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12555 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12556 The consequence was that some temporary files were not removed.
12559 unification of code in functions tempfilename() and tempfile():
12560 function tempnam() is defined in Visual Studio 6.0 and .NET
12562 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12564 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12565 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12566 - removed compiler command line option /WX: Treats all warnings as errors
12567 - update a list of source files, included into the project
12569 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12570 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12571 changed project type to Generic Project so that can be correcly converted to VS.NET project
12573 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12575 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12577 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12579 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12580 added return 0 statements after assert() to make compiler happy
12582 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12583 added newline in the def file to keep MSC compiler satisfied
12585 * sdcc/src/z80/gen.c:
12586 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12587 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12588 - solved MSC error in function aopDump()
12590 * sdcc_vc.h: define PREFIX as "\\sdcc"
12592 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12593 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12596 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12597 - Rewrote the register banking algorithm.
12598 - Added pCode live-range analysis to registers (for now, only non-used and
12599 singly-used registers optimized away)
12601 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12603 * 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.

12628 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12630 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12632 2002-03-28 Johan Knol <johan AT balder>
12634 * src/SDCCval.c: fixed bug #532436
12636 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12638 Added "char *Processor" field to the port structure.
12641 Added -p option. Allows port dependent processor to be specified.
12644 Initialized the new field char *Processor field to NULL in all ports
12647 Compiler generated registers for interrupt context saving
12648 were not getting allocated.
12650 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12653 Fixed left shift. Will promote the left side of a left shift
12654 if a) left shifting more than size of operand or b) when assigned
12655 to something size > size of left side
12657 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12659 tons of changes. Register allocation has been
12660 rewritten. Added customization for the various PICs. Flow
12661 analysis is restructured. ...
12663 * src/pic/device.h:
12666 * src/pic/device.c:
12667 Added. device.c is a PIC port hack to accomodate variations
12670 2002-03-13 Michael Hope <michaelh AT vroom>
12672 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12674 2002-03-04 johanknol <johanknol AT manik>
12676 * /src/SDCCval.c: fixed
12678 const unsigned char arr[][2] = { { 0, 1 } };

12765 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12767 * sdcc/src/SDCCloop.c:
12768 Previous fix was not good. basic blocks that have "break" or "return" are
12769 not really partof a loop , but live ranges used in these blocks should
12770 be live thru the entire loop, so set partOfLoop but don't add them to
12773 2002-02-21 <johan AT FRIJA>
12775 * src/SDCCcse.c: fixed bug #514308
12777 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12780 Fixed BUG #519583. If a conditional block ended in a return/break
12781 statement inside a loop, it was not being considered part of the loop.
12783 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12785 2002-02-10 Karl Bongers <karl AT turbobit.com>

12794 * device/examples/Makefile, examples/test3.c:
12795 Add Makefile in device/examples folder, compiles test3.c
12796 for use as a multiple module SDCDB test case.
12798 * sim/ucsim/cmd.src/cmdset.cc:
12799 Took out debug printfs in ucsim "next" command.
12801 * sim/ucsim/xa.src:
12802 Karl and Johan start ucsim XA support. Most dissassembly working,
12803 about 75% emulation done(plenty of work remaining).
12805 * sim/ucsim/z80.src:
12806 Add Z80 support to ucsim, add test-ucz80 regression test,
12807 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12808 Notice z80 compiler fails on examples/test3.c/crc code.
12810 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
12812 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

12824 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
12825 1) handle multiple send & receives from register bank1
12826 2) ralloc can now allocate DPTR1 to some liveRanges
12828 * src/SDCCsymt.c, src/SDCCsymt.h:
12829 changes to handle multiple sends & receives
12831 * src/SDCCptropt.h:
12832 added some pointer arithmetic optimization
12834 * src/SDCCptropt.c:

12836 called from anywhere (will get this working shortly)
12838 * src/SDCCopt.c: fixed for multiple sends & receives
12841 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
12842 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
12843 set preprocessor defines (depending on options)
12845 * src/SDCCicode.c, src/SDCCicode.h:
12846 changes made to handle multiple sends & receives
12849 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
