1 2006-03-23 Maarten Brock <sourceforge.brock AT dse.nl>
3 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
4 implemented patch 1120823 Thanks to Willy De la Court (normal
5 interrupts need an interrupt number now if they are made critical),
6 and enabled nesting of critical functions though not for gbz80
7 (genCritical, genEndCritical): added functions
8 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
9 * src/z80/mappings.i: added "ei" to all mappings
11 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
13 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
14 submitted by the Debian SDCC maintainer Aurelien Jarno:
15 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
16 archive with gcc 4.1 on mips and wrote the patch"
18 2006-03-16 Raphael Neider <rneider AT web.de>
20 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
21 the left operand is shorter than the result (c* = lit-c* + int),
23 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
26 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
28 * src/.version: increased version number to 2.5.5
29 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
30 linking is done manually in pic16 port's _linkEdit,
31 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
32 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
33 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
34 allocate asmop as AOP_ACC,
35 (aopForRemat): added parameter 'bool result' in function declaration,
36 (pic16_aopGet): return AOP_ACC when accessing WREG,
37 (pic16_popGetTempReg): minor modification,
38 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
40 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
41 calling function in absolute addresses,
42 (genAssign): take into account AOP_ACC asmop,
43 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
44 * src/pic16/pcoderegs.c: some debug functions and lines added,
45 * src/pic16/ralloc.c (decodeRegType): added but commented out,
46 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
48 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
49 call to allocReg, not by manually allocating a new one,
50 (pic16_assignRegisters): now before going through the register
51 allocating functions mark all registers as free. This eliminates some
52 side effects resulting from peephole parser done earlier in the backbone
54 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
56 * src/SDCCicode.c (geniCodeLogic),
57 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

75 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
76 (aopForSym, aopOp): increment asmop.allocated if reused,
77 (freeAsmop): decrement asmop.allocated and check for zero instead of
79 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
80 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
81 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,
82 genGetHbit, genGetAbit, genGetByte, genGetWord, genSwap,

101 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
102 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
104 2006-03-06 Borut Razem <borut.razem AT siol.net>
106 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
107 made the linker quiet
109 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
111 * src/pic16/gen.c (genPcall): fixed bug #1443644
112 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
113 which dumps before the function entry point a data byte which represents
114 the number of the local variables used by the specified function, added
115 'xinst' for initial support for Extended Instruction Support,
116 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
117 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
118 port->fun_prefix anymore (may change later),
119 (genFunction, genEndFunction): do not store/restore local registers for
120 _main (this should take care the --main-return command line option in
122 (genOr): removed some legacy pic-port instructions,
123 * src/pic16/genarith.c (genAddLit): re-enabled old code because
124 performing operations with SFR's causes data to be written more than
125 once to each SFR. Perhaps SFRs should be handled in special cases...
126 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
128 * src/pic16/main.c (_process_pragma): stack bound checking did not take
129 into account for stack starting position,
130 (struct OPTIONS pic16_optionsTable): added command line argument
131 --extended or -y for Extended Instruction Support,
132 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
133 (deassignLRs): *** perhaps the most important change, old 'for' code
134 (commented out for reference), didn't account for some registers which
135 were left marked 'not free' after a pointer operation. The change
136 reduces register usage a lot in some cases

2411 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2412 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2413 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,

2494 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2496 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2498 * device/lib/printf_large.c: removed inline assembly for portability and
2499 readability. Use printf_fast if speed or size are more important.
2500 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2501 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2503 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2505 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2506 prevent compiler warning
2508 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2510 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2511 moved to level 0 and declared as static. Also they are explicit
2512 placed in access bank. This was necessery because some times they
2513 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2514 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2515 optimizations. Currently only compare to unsigned char is implemented,
2516 * src/pic16/gen.c: added fReturnIdx array,
2517 * (struct resolvedIfx) is moved to gen.h and made public,
2518 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2519 * (aopForSym): added an optimization to directly store in stack of
2520 the operand of a SEND iCode,
2521 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2522 but as registers instead (AOP_REG) using the fReturnIdx array,
2523 * (pic16_freeAsmop): remove the freed register from the
2524 _G.sregsAlloc field,
2525 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2526 a compare of 'WREG',
2527 * (pic16_popGetTempRegCond): changed function prototype, now
2528 function takes also a bitVector argument v which holds the current
2529 set of registers that are allocated for stack access by aopForSym,
2530 registers allocated in aopForSym for accessing stack symbols are not
2531 any more part of the functions usedRegs field,
2532 * (genCall): some times aopOp is called for a stack variable to be
2533 send, aopForSym might perform the push, if this is true make sure
2534 that genCall doesn't push the variable twice by testing _G.resDirect,
2535 * (genFunction): changed testing for unspecified interrupt number
2536 from 256 to INTNO_UNSPEC,
2537 * modified selection scheme of frame pointer generation. Previously
2538 if function did use local registers a frame pointer was generated,
2539 now a frame pointer is generated only if function has arguments
2540 (that need PLUSW2 register access), or has stack arguments, or the
2541 compiler is not instructed to omit the frame pointer,
2542 * (genEndFunction): before restoring local registers that were saved
2543 in the function preamble, also restore the registers that *might*
2544 have been allocated for stack access,
2545 * (genRet): removed some old comments,
2546 * (genCmp, the active (RN's) version): added a call to the
2547 pic16_genCmp_special function to perform the compare with a more
2548 robust and optimized way,
2549 * (genInline): a feature has been added in inline code generation,
2550 which allows a wildcard variable substitution when writing inline
2551 assembly. Code is incomplete and experimental therefore undocumented,
2552 * (genCast): changed order of aopOp for result and right to allow
2553 aopForSym to directly load the result if possible,
2554 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2555 perform an optimized compare on some selected special occasions,
2556 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2557 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2558 generate an IVT any more,
2559 * src/pic16/main.c (pic16_optionsTable): added command line option
2561 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2562 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2564 * src/pic16/NOTES: Raphael Neider added in list of active developers
2565 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2566 jumptable_end to prevent bug #,
2567 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2568 inCond and outCond fields,
2569 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2570 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2571 turn off register spilling,
2572 * (packRegsForOneUse): synced with other ports' versions although it
2573 is not used currently,
2574 * (pic16_packRegisters): added an optimization while reading
2575 structure bitfields, some registers may be saved (malloc code is
2576 decreased by 80 bytes)
2578 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2580 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if

3222 Adding support for replacing ljmps with sjmps in jumptables
3223 generated for switch statements. For now you need to set the
3224 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3225 Now 4 algorithms for mcs51 jumptable generation are used:
3226 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3227 addresses loaded pc-relative for up to 112 cases and stack-pushing
3228 target addresses loaded with offset from dptr for up to 256 cases.

3258 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3260 * added libc directory. The current version of LibC contains string
3261 functions, ctype functions and macros and some functions of the
3262 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3263 be extensively tested in the future. Standard disclaimer here.
3264 Library is not automatically build yet. But one can build it by
3265 invoking 'make' inside the libc directory.

3275 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3276 * (pic16_storeForReturn): optimized return of 0,
3277 * (genCmp): experimental code for new genCmp which uses PIC18's
3278 special compare&skip instructions. Initial tests fail some times
3279 with variables grater than 1 byte in size, so new code is disabled,
3280 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3282 * (genCast): began a fix to optimize the casting of a bit to another
3283 bit, now assigning a bitfield to another bitfield will fail, sorry,
3284 * src/pic16/main.c: disabled the use of lr-support feature,
3285 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3291 * (isBankInstruction): modified to return 0 for no banking instruction,
3292 and 1 for banking instruction,
3293 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3294 caused stop processing pCodes after a inline assembly block,
3295 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3296 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3297 registers when it shouldn't,
3298 * src/pic16/ralloc.c (allocReg): add preliminary support for
3299 supporting a limited set of temporary registers,
3301 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3307 (genFunction): optimize RECEIVE iCodes in reentrant functions
3309 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6309 loaded with the linker search paths (-L arguments) and the libraries
6310 to be linked with the current source (-l arguments). Changes
6311 currently will affect only the pic16 port.
6312 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6313 include path the port specific paths and port specific libraries,
6314 * gplink command now contains the $3 argument,

6332 Documenting changes from previous commits.
6333 * configure.in (version 1.56),
6334 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6335 when generating output files to configure the pic16 library,
6336 but now I've commented it out, since gputils aren't installed in the
6337 SF compile farm, so library won't compile
6339 * device/lib/Makefile.in (version 1.56): initially I've added in
6340 target 'all' the prerequestive 'model-pic16' so it compiled the
6341 pic16 library, but now I've commented it out for the same reasons
6343 * added targets 'model-pic16' and 'objects-pic16' to compile the
6345 * added target 'port-specific-objects-pic16' to handle the
6346 generated libraries and copy them into the build/ directory
6347 * added target 'clean-intermediate-pic16' to clean intermediate
6348 files into pic16 directory
6349 * in target 'installdirs' added line to create directory pic16 in
6350 the installation path

6353 added lines to copy all header files to installation path,
6354 * in target 'installdirs' added line create directory for pic16
6355 headers in the installation path

6589 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6591 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
6593 * support/valdiag/tests/overflow.c: added
6594 * src/SDCCast.c (decorateType),
6595 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6596 LEFT_OP (left shift)
6598 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6600 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6601 (default behaviour).
6603 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6605 A python script to validate compiler diagnostic messages. It can be
6606 used to verify that sdcc complains about bad c source code and
6607 gives a good location of the error.
6608 * support/valdiag/Makefile,
6609 * support/valdiag/valdiag.py,
6610 * support/valdiag/tests/*
6612 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6614 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6615 * src/SDCCsymt.c (newEnumType),
6617 * support/Util/SDCCerr.c,
6618 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6620 * support/regression/tests/enum.c: added test for enum values that
6621 require at least 2 bytes of storage.
6623 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6625 * src/common.h: added ifndef/define/endif macros
6626 around the header file.
6627 Bug reported from Jesus Calvino-Fraga
6629 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6631 * sdcc.spec: updated
6632 * device/include/Makefile.in: don't install CVS directories
6633 * device/lib/Makefile.in: added removal of CVS directories after install
6634 * doc/Makefile: fixed install, added local_icons
6635 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6636 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6637 * src/ds390/gen.c (genRightShift): fixed bug #870788
6638 * src/SDCCast.c (decorateType): fixed bug #870781
6640 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6642 PIC16 port related changes:
6643 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6644 added variable stackPos,
6646 * gen.c: genCall, assignResultValue: added support for
6647 pushing/retrieving function parameters to/from stack,
6648 genFunction,genEndFunction: setup stack frame for the
6650 genAddrOf: will be changed according to bug 863624
6652 * added files genutils.c and genutils.h which contain gen*
6653 debugged and optimised functions extracted from gen.c
6655 * glue.c: added variable 'externs' which holds extern symbols,
6656 pic16emitRegularMap: is modified to properly handle relocatable
6657 symbols under the new scheme,
6658 pic16createInterruptVect: is modified
6659 pic16printPublics: is modified to emit 'global' assembler directives,
6660 added pic16_printExterns to print extern symbols,
6661 pic16glue: initializes stack/frame pointer in the beginning of
6662 the assembly output. Temporary hack, will be corrected later,
6663 because gplink yet does not support stack and SDCC does not
6664 yet support a type of crt0.o object to create the final binary.
6666 * Removed many lines that contain 8051 legacy code.
6667 * The code is finally placed under a 'code' directive.
6668 * Added port specific options.
6670 * _process_pragma: simplified since now we do not need *special*
6671 include file to define SFR registers. But a separate header
6672 will be needed. This will be developed later.
6673 * _pic16_parseOptions: added, parses port specific options:
6674 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6675 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6676 --preplace-udata-with=
6678 * _pic16_setDefaultOptions: modified to initialize section names,
6679 but hack is temporarly out of order since it needs improvement.
6680 * _pic16_genAssemblerPreamble: configuration words are emitted by
6681 their address instead of their name. This part is incomplete and
6682 supports only the 18Fxx2 devices. Other devices will emit an error
6683 during assembly since they do not contain the same set of config
6685 * _pic16_genIVT: is modified,
6687 * pcode.c: added definitions for some hardware registers that are needed
6689 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6690 All PCI entries are updated. Now LFSR is supported.
6691 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6692 * added pic16_newpCodeOpLit2 to support instructions with
6693 two literal arguments
6694 * pic16_pCode2str: corrected code that emits assembler instructions
6695 with two literal operands and those that have an access bit modifier
6696 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6697 this fixes a bug which caused some labels to be lost, when an
6698 assembler directive was added, i.e. banksel,
6699 * pic16_FixRegisterBanking: improved logic that causes the insertion
6701 * InlineFunction: functions that are called once, are not any more
6702 inlined. This can be a port option in the future,
6704 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6706 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6707 hold the corresponding uninitialized symbols,
6708 * pic16_allocProcessorRegister: registers have explicit marked the
6710 * pic16_allocInternalRegister: registers are explicit marked as
6712 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6713 processing list, so bit registers were lost,
6716 * ralloc.h: added field 'accessBank' and original symbol operand
6717 in register definition,
6718 * removed the field isMapped from register definition,
6720 ** Several functions have been removed from various sources:
6721 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6722 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6723 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6724 pic16_assignRelocatableRegisters
6726 ** others have been introduced:
6727 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6728 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6730 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6732 * support/scripts/inc2h.pl: changed definition of BIT_AT
6733 to emit 'sbit at' instead of 'bit at'. This was a request.
6735 PIC16 port related preliminary changes:
6736 * gen.c: prefixed function popRegFromString with
6737 pic16_ and all references to it corrected
6738 * pcode.c: all pic16_pc_* hardware registers prefixed
6739 with underscore (_),
6740 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6741 * ralloc.c: newReg(): when register is REG_SFR then
6742 set address to rIdx,
6743 pic16_allocProcessorRegister(): marks register wasUsed=0
6744 pic16_writeUsedRegs(): added a call to assign processor
6745 registers via pic16_assignFixedRegisters
6747 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6749 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6750 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6751 variables in unused register banks. Also the SSEG is placed
6752 wherever there is enough space for it, and IDATA can be anywhere
6753 in internal RAM. For now compile using -Wl-Y[stack_size].
6754 The mem file is different for this option as well, since it
6755 makes no sense of talking about DSEG lenght.
6757 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6759 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6760 in certain cases, e.g. when ROM assignment, patch provided
6761 from Albert den Haan.
6763 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6906 * src/mcs51/peephole.def,
6907 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6919 multiply defined with mismatching "at" address.
6921 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6923 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

7002 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7004 * src/SDCCast.c (decorateType): disabled a transformation I added in
7005 revision 1.188 (access to fields of a structure at an absolute address);
7006 it breaks with bitfields, extern declarations, and gcse analysis.
7007 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7008 could be assigned through a pointer, so don't complain.
7009 * src/SDCCast.c (astErrors),
7011 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7591 genCodePointerGet, genGenPointerGet, genFarPointerSet,
7592 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
7593 (ralloc doesn't intentionally do this now, but perhaps later)
7594 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
7595 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

7646 * src/SDCCsymt.c (sclsFromPtr),
7648 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7649 support for standard C idiom of memory mapped variables; for
7650 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7651 to xdata int at 0x1234 tempvar = 1.
7652 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7653 provided by Akiya ISHIDA

7669 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7671 Fixed bug #621531 (const & volatile confusion in the type chain).
7672 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7673 refer to the const or volatile state of the pointer itself.

7738 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7739 pcoderegs.h, ralloc.c, ralloc.h
7740 * main.c: added top header and GPL license notice

7764 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7765 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7766 fetching of the pointer
7767 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7768 copied from genNearPointerSet()
7769 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7770 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7771 If they pop r0/r1 they must be called in the opposite order than aopOp().
7772 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7773 (resp. --stack-auto), prepared for --xstack

7784 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7786 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7787 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7788 type for bits was changed. It resulted in bit variables becoming
7789 global, which is not permitted in PIC 14 assembly output.
7791 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7793 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7806 A few small changes that speed up the peephole optimizer.
7810 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7812 Try to make the peephole optimizer smarter by maintaining
7813 an association between the assembly source code and the
7814 iCodes that originated them. Put this information to use
7815 with a new peephole rule condition "notVolatile" so that
7816 the rules can be aggressive yet still safe.
7821 * src/mcs51/peeph.def
7823 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7827 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7828 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7829 if the left or right operand symbols have the accuse flag set.
7831 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7833 Changed the type of the result of the ! (NOT) operator to char;
7834 previously it returned the same type as the source. This allows
7835 us to eliminate all the genFloatNot functions (all of its target
7836 implementations were very buggy) since !float can use the same
7839 * src/SDCCicode.c (ast2iCode): ! returns char

7848 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7849 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7850 during interrupts. Ensure WSAVE is located at a shared bank address.
7851 2. Fixed page selection in some places
7852 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7853 the registers name strings.
7854 4. Fixed "signed / unsigned compare" compiler warnings.
7855 5. The PIC port manages its own allocation of the general purpose
7856 registers, but makes no attempt to reuse them. As a result when
7857 compiling it soon runs out of general purpose registers. Some
7858 additional code was added to the files pcode.c and device.c to walk
7859 through the function call tree and rename the registers so that they
7869 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7870 genPlus() & genMinus() when the result is the same as left or right
7872 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7876 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7878 Made bitfield a distinct type from bit so that bitfields
7879 convert as per ANSI C and bits retain their traditional
7880 boolean style behaviour. Implemented bitfield support in
7888 * src/ds390/gen.c: bit v bitfield split
7889 * src/z80/gen.c: New support for bitfields
7890 * support/regression/tests/bitfields.c: reenabled z80,
7893 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7895 Rules 246.x, 247.x relate to bitfields, the others speed up
7896 access to xdata mapped I/O devices.
7898 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7900 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7902 Cleaned up genPackBits and genUnpackBits and added two helper
7903 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7904 for literal assignments in genPackBits (thanks to Frieder for
7910 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7912 Fixed bug #748310 (pointer to function type mishandled when the
7913 function name is omitted). Also fixed a SIGSEGV when a function
7914 attribute (reentrant, etc) is used on a non-function or on a
7915 function but misplaced before the parameter list.
7917 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7919 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7920 * support/Util/SDCCerr.h,
7921 * support/Util/SDCCerr.c: Added func attr misuse error msg

7942 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7944 Made the constant following the "interrupt" keyword optional. If
7945 omitted, the function will not automatically be given an entry
7946 in the interrupt vector table (similar to #pragma NOIV, but
7947 less syntacticly kludgy). The interrupt number is also now
7948 range checked. Also fixed a bug in the high order bit example

7962 * src/SDCCicode.c (operandOperation): rewritten some ops
7963 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7964 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7966 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7967 be re-activated by defining REDUCE_LITERALS)
7968 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7969 unsigned, but are signed by default
7970 * src/SDCCval.c (constVal): rearranged
7971 * src/SDCCval.c (valMod): preliminary fix
7972 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8014 constants are unsigned; added recognition of "u" flag for unsigned
8015 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8016 * src/SDCCval.c (valDiv, valMod): fixed signdness
8017 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8018 signedness of modulo, left and right shift

8478 added if/endif conditional macros to remove options help
8479 messages from optionsTable when a port is not configured, added
8480 support for the PIc16 port in the ports table, when executing
8481 the compiler with no port specified on command line, a default
8482 port is selected with the new macro DEFAULT_PORT which is
8483 defined in port.h, in setDefaultOptions() linkOptions is removed
8484 from initialization assignment, since now it is a set,
8485 parseCmdLine uses setParseWithComma for linkOptions, in
8486 linkEdit() linkOptions are accessed with new function indexSet()
8487 which returns the i'th item of a set variable. See SDCCset.c, in
8488 linkEdit() when calling buildCmdLine(), added linkOptions as
8489 last argument. Now users can pass arguments to gplink via the
8490 -Wl option, main() uses pic16glue() to glue up pic16 programs

8504 gpasm complaining and test the linkage with gplink, _linkCmd and
8505 _asmCmd changed to be more gplink and gpasm friendly
8506 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8507 produced an error when parsed, peep rule 12 is added to utilize
8508 movff, but it is commented out since the pCode does not support
8509 yet a command with 2 address arguments
8511 2003-05-18 <johan AT balder>
8513 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8540 2003-05-11 Borut Razem <borut.razem AT siol.net>
8542 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9526 * support/regression/fwk/lib/timeout.c: fix usage string
9528 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9529 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9531 2003-01-07 <johan AT balder>
9533 * src/SDCCast.c (decorateType): fixed bug #600035
9535 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9536 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9546 2003-01-06 <johan AT balder>
9548 * src/SDCCicode.c: fixed array add
9550 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9551 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9552 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9554 2003-01-04 <johan AT balder>
9556 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9558 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9559 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9561 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9562 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9563 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9565 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9566 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9568 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9569 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9571 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9572 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9574 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9576 * in \sdcc\as\mcs51\ changed these files in order to create an
9577 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9578 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9579 following files to include the previous two files: aslink.dsp,
9580 Makefile.aslink, Makefile.bcc, and Makefile.in.
9582 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9583 .adb instead of .cdb
9585 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9587 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9588 value from option --iram-size.
9590 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9592 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9595 2002-09-18 <wiml AT hhhh.org>
9597 * SDCClrange.h: exposed setFromRange() and setToRange()
9598 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9599 packRegsForAccUse() (bug 542397)
9600 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9601 multiple times and emitting the fetch operations more than once
9602 added aopGetUsesAcc() function to allow binary operators to
9603 fetch their operands in the correct order; made genMinus() emit
9604 compact code for X = LITERAL - Y
9606 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9607 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9608 sprintf() in line 1267.
9610 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9611 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9614 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9615 Changes to aslink (All the changes are marked with 'JCF'):
9617 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9620 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9621 area BSEG. Also moves, if possible, the DATA area down into the internal
9622 ram so more space is available.
9624 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9627 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9628 not bytes. Function summary() which creates a memory usage summary
9629 file with extension .mem. Reports of overlaping stack and small stack
9630 size. If the space for the stack is less than 16 bytes aslink trows a
9633 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9634 the 8051. Option 'y' for memory summary output file.
9636 Changes to sdcc (All the changes are marked with 'JCF'):
9638 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9640 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9641 overlaying area for it (uses RegBankUsed[4]).
9643 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9644 bank zero as used by default. By default aslink locates the stack
9645 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9646 the creation of the .mem file. Delegates the allocation of data area
9647 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9648 the begining of the stack area to aslink.
9650 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9651 glue() in SDCCglue.c creates an area for it.
9653 2002-09-03 Borut Razem <borut.razem AT siol.net>
9654 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9655 sdcc/src/pic/glue.c:
9656 introduced atexit() handler for teporay files removal in case of
9657 errors, assertions, ...
9659 2002-08-29 Borut Razem <borut.razem AT siol.net>
9660 * sdcc/support/cpp2/auto-host_vc_in.h:
9661 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9662 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9663 Maybe there is a similar problem with BORLANDC? It should be checked!
9665 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9666 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9667 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9668 was not executed, and the compiler (cl) launched a warning:
9669 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9671 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9672 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9674 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9675 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9677 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9678 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9679 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9680 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9681 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9682 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9683 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9684 - added Release configuration in VS projects
9685 - review of compiler an linker options
9686 - VC .exe files are generated in bin_vc directory, not to interfere
9687 with binaries generated from other projects (cygwin, mingw, bcc ...)
9689 * sdcc/src/yacc.dsp: added
9691 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9692 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9693 and insert the version number definitions from .version
9695 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9697 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9698 added - genarate auto-host.h using auto-host_vc_in.h as template
9701 removed from CVS, generated automatically
9703 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9704 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9706 2002-08-11 Borut Razem <borut.razem AT siol.net>
9707 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9709 2002-08-10 Borut Razem <borut.razem AT siol.net>
9710 * src/SDCCmain.c (main):
9711 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9712 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9713 The consequence was that some temporary files were not removed.
9716 unification of code in functions tempfilename() and tempfile():
9717 function tempnam() is defined in Visual Studio 6.0 and .NET
9719 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9721 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9722 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9723 - removed compiler command line option /WX: Treats all warnings as errors
9724 - update a list of source files, included into the project
9726 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9727 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9728 changed project type to Generic Project so that can be correcly converted to VS.NET project
9730 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9732 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9734 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9736 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9737 added return 0 statements after assert() to make compiler happy
9739 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9740 added newline in the def file to keep MSC compiler satisfied
9742 * sdcc/src/z80/gen.c:
9743 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9744 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9745 - solved MSC error in function aopDump()
9747 * sdcc_vc.h: define PREFIX as "\\sdcc"
9749 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9750 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9753 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9754 - Rewrote the register banking algorithm.
9755 - Added pCode live-range analysis to registers (for now, only non-used and
9756 singly-used registers optimized away)
9758 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9760 * 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.

9785 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9787 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9789 2002-03-28 Johan Knol <johan AT balder>
9791 * src/SDCCval.c: fixed bug #532436
9793 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9795 Added "char *Processor" field to the port structure.
9798 Added -p option. Allows port dependent processor to be specified.
9801 Initialized the new field char *Processor field to NULL in all ports
9804 Compiler generated registers for interrupt context saving
9805 were not getting allocated.
9807 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9810 Fixed left shift. Will promote the left side of a left shift
9811 if a) left shifting more than size of operand or b) when assigned
9812 to something size > size of left side
9814 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9816 tons of changes. Register allocation has been
9817 rewritten. Added customization for the various PICs. Flow
9818 analysis is restructured. ...
9824 Added. device.c is a PIC port hack to accomodate variations
9827 2002-03-13 Michael Hope <michaelh AT vroom>
9829 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9831 2002-03-04 johanknol <johanknol AT manik>
9833 * /src/SDCCval.c: fixed
9835 const unsigned char arr[][2] = { { 0, 1 } };
9836 t18.c:1: error: Initializer element is not constant
9838 2002-03-04 bela <bela AT manik>
9840 * /device/include/mcs51reg.h:
9841 ds89c420 register definition update
9843 2002-03-03 <johan AT FRIJA>

9922 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9924 * sdcc/src/SDCCloop.c:
9925 Previous fix was not good. basic blocks that have "break" or "return" are
9926 not really partof a loop , but live ranges used in these blocks should
9927 be live thru the entire loop, so set partOfLoop but don't add them to
9930 2002-02-21 <johan AT FRIJA>
9932 * src/SDCCcse.c: fixed bug #514308
9934 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9937 Fixed BUG #519583. If a conditional block ended in a return/break
9938 statement inside a loop, it was not being considered part of the loop.
9940 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9942 2002-02-10 Karl Bongers <karl AT turbobit.com>
9945 Fixed up SDCDB debugger somewhat. Updated debugger/README
9946 with lots of comments and notes.
9948 * device/examples/test2.c:
9949 Fix bug, "red" variable not being initialized(compiler complained).
9951 * device/examples/Makefile, examples/test3.c:
9952 Add Makefile in device/examples folder, compiles test3.c
9953 for use as a multiple module SDCDB test case.
9955 * sim/ucsim/cmd.src/cmdset.cc:
9956 Took out debug printfs in ucsim "next" command.
9959 Karl and Johan start ucsim XA support. Most dissassembly working,
9960 about 75% emulation done(plenty of work remaining).
9962 * sim/ucsim/z80.src:
9963 Add Z80 support to ucsim, add test-ucz80 regression test,
9964 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9965 Notice z80 compiler fails on examples/test3.c/crc code.
9967 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9969 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

9977 from a memory mapped port
9978 2) added __builtin_memcmp
9979 3) added __builtin_swapw swap bytes of a short
9981 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9982 1) handle multiple send & receives from register bank1
9983 2) ralloc can now allocate DPTR1 to some liveRanges
9985 * src/SDCCsymt.c, src/SDCCsymt.h:
9986 changes to handle multiple sends & receives
9989 added some pointer arithmetic optimization
9992 added some pointer arithmetic optimizations but not stable yet so not
9993 called from anywhere (will get this working shortly)
9995 * src/SDCCopt.c: fixed for multiple sends & receives
9998 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9999 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10000 set preprocessor defines (depending on options)
10002 * src/SDCCicode.c, src/SDCCicode.h:
10003 changes made to handle multiple sends & receives
10006 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
10008 * src/SDCCcse.c, src/SDCCcse.h:
