59 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
60 which dumps before the function entry point a data byte which represents
61 the number of the local variables used by the specified function, added
62 'xinst' for initial support for Extended Instruction Support,
63 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
64 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
65 port->fun_prefix anymore (may change later),

79 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
80 (deassignLRs): *** perhaps the most important change, old 'for' code
81 (commented out for reference), didn't account for some registers which
82 were left marked 'not free' after a pointer operation. The change
83 reduces register usage a lot in some cases

2356 * src/SDCCglobal.h (struct options),
2358 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2359 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2360 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2361 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2362 always available in leading double underscore form. The C99 support is
2363 mostly missing, but it's a start.
2364 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2443 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2445 * device/lib/printf_large.c: removed inline assembly for portability and
2446 readability. Use printf_fast if speed or size are more important.
2447 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2448 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2450 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2452 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2453 prevent compiler warning
2455 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2457 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2458 moved to level 0 and declared as static. Also they are explicit
2459 placed in access bank. This was necessery because some times they
2460 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2461 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2462 optimizations. Currently only compare to unsigned char is implemented,
2463 * src/pic16/gen.c: added fReturnIdx array,
2464 * (struct resolvedIfx) is moved to gen.h and made public,
2465 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2466 * (aopForSym): added an optimization to directly store in stack of
2467 the operand of a SEND iCode,
2468 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2469 but as registers instead (AOP_REG) using the fReturnIdx array,
2470 * (pic16_freeAsmop): remove the freed register from the
2471 _G.sregsAlloc field,
2472 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2473 a compare of 'WREG',
2474 * (pic16_popGetTempRegCond): changed function prototype, now
2475 function takes also a bitVector argument v which holds the current
2476 set of registers that are allocated for stack access by aopForSym,
2477 registers allocated in aopForSym for accessing stack symbols are not
2478 any more part of the functions usedRegs field,
2479 * (genCall): some times aopOp is called for a stack variable to be
2480 send, aopForSym might perform the push, if this is true make sure
2481 that genCall doesn't push the variable twice by testing _G.resDirect,
2482 * (genFunction): changed testing for unspecified interrupt number
2483 from 256 to INTNO_UNSPEC,
2484 * modified selection scheme of frame pointer generation. Previously
2485 if function did use local registers a frame pointer was generated,
2486 now a frame pointer is generated only if function has arguments
2487 (that need PLUSW2 register access), or has stack arguments, or the
2488 compiler is not instructed to omit the frame pointer,
2489 * (genEndFunction): before restoring local registers that were saved
2490 in the function preamble, also restore the registers that *might*
2491 have been allocated for stack access,
2492 * (genRet): removed some old comments,
2493 * (genCmp, the active (RN's) version): added a call to the
2494 pic16_genCmp_special function to perform the compare with a more
2495 robust and optimized way,
2496 * (genInline): a feature has been added in inline code generation,
2497 which allows a wildcard variable substitution when writing inline
2498 assembly. Code is incomplete and experimental therefore undocumented,
2499 * (genCast): changed order of aopOp for result and right to allow
2500 aopForSym to directly load the result if possible,
2501 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2502 perform an optimized compare on some selected special occasions,
2503 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2504 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2505 generate an IVT any more,
2506 * src/pic16/main.c (pic16_optionsTable): added command line option
2508 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2509 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2511 * src/pic16/NOTES: Raphael Neider added in list of active developers
2512 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2513 jumptable_end to prevent bug #,
2514 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2515 inCond and outCond fields,
2516 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2517 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2518 turn off register spilling,
2519 * (packRegsForOneUse): synced with other ports' versions although it
2520 is not used currently,
2521 * (pic16_packRegisters): added an optimization while reading
2522 structure bitfields, some registers may be saved (malloc code is
2523 decreased by 80 bytes)
2525 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2527 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2528 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2529 this can be optimized more?
2531 2005-03-10 Raphael Neider <rneider AT web.de>
2533 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2534 genNearPointerGet): (hopefully) fixed access to bitfields via
2535 pointers (p->bitN = x; and x = p->bitN; failed)
2537 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3169 Adding support for replacing ljmps with sjmps in jumptables
3170 generated for switch statements. For now you need to set the
3171 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3172 Now 4 algorithms for mcs51 jumptable generation are used:
3173 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3174 addresses loaded pc-relative for up to 112 cases and stack-pushing
3175 target addresses loaded with offset from dptr for up to 256 cases.

3205 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3207 * added libc directory. The current version of LibC contains string
3208 functions, ctype functions and macros and some functions of the
3209 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3210 be extensively tested in the future. Standard disclaimer here.
3211 Library is not automatically build yet. But one can build it by
3212 invoking 'make' inside the libc directory.

3223 * (pic16_storeForReturn): optimized return of 0,
3224 * (genCmp): experimental code for new genCmp which uses PIC18's
3225 special compare&skip instructions. Initial tests fail some times
3226 with variables grater than 1 byte in size, so new code is disabled,
3227 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3229 * (genCast): began a fix to optimize the casting of a bit to another
3230 bit, now assigning a bitfield to another bitfield will fail, sorry,

3239 and 1 for banking instruction,
3240 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3241 caused stop processing pCodes after a inline assembly block,
3242 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3243 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3244 registers when it shouldn't,
3245 * src/pic16/ralloc.c (allocReg): add preliminary support for
3246 supporting a limited set of temporary registers,
3248 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3250 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3253 (loadRegFromAop): recognize CLRH optimization,
3254 (genFunction): optimize RECEIVE iCodes in reentrant functions
3256 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3258 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6256 loaded with the linker search paths (-L arguments) and the libraries
6257 to be linked with the current source (-l arguments). Changes
6258 currently will affect only the pic16 port.
6259 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6260 include path the port specific paths and port specific libraries,
6261 * gplink command now contains the $3 argument,
6262 * src/pic16/device.h,
6263 * src/pic16/device.c,: structure PIC_device is made public and

6279 Documenting changes from previous commits.
6280 * configure.in (version 1.56),
6281 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6282 when generating output files to configure the pic16 library,
6283 but now I've commented it out, since gputils aren't installed in the
6284 SF compile farm, so library won't compile
6286 * device/lib/Makefile.in (version 1.56): initially I've added in
6287 target 'all' the prerequestive 'model-pic16' so it compiled the
6288 pic16 library, but now I've commented it out for the same reasons
6290 * added targets 'model-pic16' and 'objects-pic16' to compile the
6292 * added target 'port-specific-objects-pic16' to handle the
6293 generated libraries and copy them into the build/ directory
6294 * added target 'clean-intermediate-pic16' to clean intermediate
6295 files into pic16 directory
6296 * in target 'installdirs' added line to create directory pic16 in

6599 * added files genutils.c and genutils.h which contain gen*
6600 debugged and optimised functions extracted from gen.c
6602 * glue.c: added variable 'externs' which holds extern symbols,
6603 pic16emitRegularMap: is modified to properly handle relocatable
6604 symbols under the new scheme,
6605 pic16createInterruptVect: is modified
6606 pic16printPublics: is modified to emit 'global' assembler directives,
6607 added pic16_printExterns to print extern symbols,
6608 pic16glue: initializes stack/frame pointer in the beginning of
6609 the assembly output. Temporary hack, will be corrected later,
6610 because gplink yet does not support stack and SDCC does not
6611 yet support a type of crt0.o object to create the final binary.
6613 * Removed many lines that contain 8051 legacy code.
6614 * The code is finally placed under a 'code' directive.
6615 * Added port specific options.
6617 * _process_pragma: simplified since now we do not need *special*
6618 include file to define SFR registers. But a separate header
6619 will be needed. This will be developed later.
6620 * _pic16_parseOptions: added, parses port specific options:
6621 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6622 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6623 --preplace-udata-with=
6625 * _pic16_setDefaultOptions: modified to initialize section names,
6626 but hack is temporarly out of order since it needs improvement.
6627 * _pic16_genAssemblerPreamble: configuration words are emitted by
6628 their address instead of their name. This part is incomplete and
6629 supports only the 18Fxx2 devices. Other devices will emit an error
6630 during assembly since they do not contain the same set of config
6632 * _pic16_genIVT: is modified,
6634 * pcode.c: added definitions for some hardware registers that are needed
6636 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6637 All PCI entries are updated. Now LFSR is supported.
6638 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6639 * added pic16_newpCodeOpLit2 to support instructions with
6640 two literal arguments
6641 * pic16_pCode2str: corrected code that emits assembler instructions
6642 with two literal operands and those that have an access bit modifier
6643 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6644 this fixes a bug which caused some labels to be lost, when an
6645 assembler directive was added, i.e. banksel,
6646 * pic16_FixRegisterBanking: improved logic that causes the insertion
6648 * InlineFunction: functions that are called once, are not any more
6649 inlined. This can be a port option in the future,
6651 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6653 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6654 hold the corresponding uninitialized symbols,
6655 * pic16_allocProcessorRegister: registers have explicit marked the
6657 * pic16_allocInternalRegister: registers are explicit marked as
6659 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6660 processing list, so bit registers were lost,
6663 * ralloc.h: added field 'accessBank' and original symbol operand
6664 in register definition,
6665 * removed the field isMapped from register definition,
6667 ** Several functions have been removed from various sources:
6668 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6669 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6670 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6671 pic16_assignRelocatableRegisters
6673 ** others have been introduced:
6674 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6675 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6677 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6679 * support/scripts/inc2h.pl: changed definition of BIT_AT
6680 to emit 'sbit at' instead of 'bit at'. This was a request.
6682 PIC16 port related preliminary changes:
6683 * gen.c: prefixed function popRegFromString with
6684 pic16_ and all references to it corrected
6685 * pcode.c: all pic16_pc_* hardware registers prefixed
6686 with underscore (_),
6687 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6688 * ralloc.c: newReg(): when register is REG_SFR then
6689 set address to rIdx,
6690 pic16_allocProcessorRegister(): marks register wasUsed=0
6691 pic16_writeUsedRegs(): added a call to assign processor
6692 registers via pic16_assignFixedRegisters
6694 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6696 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6697 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6698 variables in unused register banks. Also the SSEG is placed
6699 wherever there is enough space for it, and IDATA can be anywhere
6700 in internal RAM. For now compile using -Wl-Y[stack_size].
6701 The mem file is different for this option as well, since it
6702 makes no sense of talking about DSEG lenght.
6704 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6706 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6707 in certain cases, e.g. when ROM assignment, patch provided
6708 from Albert den Haan.
6710 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6853 * src/mcs51/peephole.def,
6854 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6866 multiply defined with mismatching "at" address.
6868 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6949 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6951 * src/SDCCast.c (decorateType): disabled a transformation I added in
6952 revision 1.188 (access to fields of a structure at an absolute address);
6953 it breaks with bitfields, extern declarations, and gcse analysis.
6954 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6955 could be assigned through a pointer, so don't complain.
6956 * src/SDCCast.c (astErrors),
6958 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7058 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7060 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7061 uninitialized variables) for the mcs51. Set environment variable

7712 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7713 fetching of the pointer
7714 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7715 copied from genNearPointerSet()
7716 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7717 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7733 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7734 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7735 type for bits was changed. It resulted in bit variables becoming
7736 global, which is not permitted in PIC 14 assembly output.
7738 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7740 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7753 A few small changes that speed up the peephole optimizer.
7757 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7759 Try to make the peephole optimizer smarter by maintaining
7760 an association between the assembly source code and the
7761 iCodes that originated them. Put this information to use
7762 with a new peephole rule condition "notVolatile" so that
7763 the rules can be aggressive yet still safe.
7768 * src/mcs51/peeph.def
7770 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7774 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7775 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7776 if the left or right operand symbols have the accuse flag set.
7778 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7780 Changed the type of the result of the ! (NOT) operator to char;
7781 previously it returned the same type as the source. This allows
7782 us to eliminate all the genFloatNot functions (all of its target
7783 implementations were very buggy) since !float can use the same
7786 * src/SDCCicode.c (ast2iCode): ! returns char

7795 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7796 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7797 during interrupts. Ensure WSAVE is located at a shared bank address.
7798 2. Fixed page selection in some places
7799 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7800 the registers name strings.
7801 4. Fixed "signed / unsigned compare" compiler warnings.
7802 5. The PIC port manages its own allocation of the general purpose
7803 registers, but makes no attempt to reuse them. As a result when
7804 compiling it soon runs out of general purpose registers. Some
7805 additional code was added to the files pcode.c and device.c to walk
7806 through the function call tree and rename the registers so that they
7816 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7817 genPlus() & genMinus() when the result is the same as left or right

7823 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7825 Made bitfield a distinct type from bit so that bitfields
7826 convert as per ANSI C and bits retain their traditional
7827 boolean style behaviour. Implemented bitfield support in
7835 * src/ds390/gen.c: bit v bitfield split
7836 * src/z80/gen.c: New support for bitfields
7837 * support/regression/tests/bitfields.c: reenabled z80,
7840 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7842 Rules 246.x, 247.x relate to bitfields, the others speed up
7843 access to xdata mapped I/O devices.
7845 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7847 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7849 Cleaned up genPackBits and genUnpackBits and added two helper
7850 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7851 for literal assignments in genPackBits (thanks to Frieder for
7857 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7859 Fixed bug #748310 (pointer to function type mishandled when the
7860 function name is omitted). Also fixed a SIGSEGV when a function
7861 attribute (reentrant, etc) is used on a non-function or on a
7862 function but misplaced before the parameter list.
7864 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7866 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7867 * support/Util/SDCCerr.h,
7868 * support/Util/SDCCerr.c: Added func attr misuse error msg

7889 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7891 Made the constant following the "interrupt" keyword optional. If
7892 omitted, the function will not automatically be given an entry
7893 in the interrupt vector table (similar to #pragma NOIV, but
7894 less syntacticly kludgy). The interrupt number is also now
7895 range checked. Also fixed a bug in the high order bit example

7909 * src/SDCCicode.c (operandOperation): rewritten some ops
7910 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7911 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7913 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7914 be re-activated by defining REDUCE_LITERALS)
7915 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7916 unsigned, but are signed by default
7917 * src/SDCCval.c (constVal): rearranged
7918 * src/SDCCval.c (valMod): preliminary fix
7919 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7961 constants are unsigned; added recognition of "u" flag for unsigned
7962 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7963 * src/SDCCval.c (valDiv, valMod): fixed signdness
7964 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7965 signedness of modulo, left and right shift

8424 * src/SDCCmain.c: linkOptions is changed to set *,
8425 added if/endif conditional macros to remove options help
8426 messages from optionsTable when a port is not configured, added
8427 support for the PIc16 port in the ports table, when executing
8428 the compiler with no port specified on command line, a default
8429 port is selected with the new macro DEFAULT_PORT which is
8430 defined in port.h, in setDefaultOptions() linkOptions is removed
8431 from initialization assignment, since now it is a set,
8432 parseCmdLine uses setParseWithComma for linkOptions, in
8433 linkEdit() linkOptions are accessed with new function indexSet()
8434 which returns the i'th item of a set variable. See SDCCset.c, in
8435 linkEdit() when calling buildCmdLine(), added linkOptions as
8436 last argument. Now users can pass arguments to gplink via the
8437 -Wl option, main() uses pic16glue() to glue up pic16 programs

8449 * src/pic16/glue.c: commented out some error producing lines
8450 * src/pic16/main.c: __config directives are commented out to stop
8451 gpasm complaining and test the linkage with gplink, _linkCmd and
8452 _asmCmd changed to be more gplink and gpasm friendly
8453 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8454 produced an error when parsed, peep rule 12 is added to utilize
8455 movff, but it is commented out since the pCode does not support
8456 yet a command with 2 address arguments
8458 2003-05-18 <johan AT balder>
8460 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8485 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8487 2003-05-11 Borut Razem <borut.razem AT siol.net>
8489 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8490 the path of bin directory, so that PATH is the only env. variable, which has to be set
8491 in case of standard installation.
8492 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9519 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9521 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9523 * in \sdcc\as\mcs51\ changed these files in order to create an
9524 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9525 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9526 following files to include the previous two files: aslink.dsp,
9527 Makefile.aslink, Makefile.bcc, and Makefile.in.
9529 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9530 .adb instead of .cdb
9532 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9534 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9535 value from option --iram-size.
9537 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9539 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9542 2002-09-18 <wiml AT hhhh.org>
9544 * SDCClrange.h: exposed setFromRange() and setToRange()
9545 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9546 packRegsForAccUse() (bug 542397)
9547 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9548 multiple times and emitting the fetch operations more than once
9549 added aopGetUsesAcc() function to allow binary operators to
9550 fetch their operands in the correct order; made genMinus() emit
9551 compact code for X = LITERAL - Y
9553 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9554 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9555 sprintf() in line 1267.
9557 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9558 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9561 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9562 Changes to aslink (All the changes are marked with 'JCF'):
9564 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9567 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9568 area BSEG. Also moves, if possible, the DATA area down into the internal
9569 ram so more space is available.
9571 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9574 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9575 not bytes. Function summary() which creates a memory usage summary
9576 file with extension .mem. Reports of overlaping stack and small stack
9577 size. If the space for the stack is less than 16 bytes aslink trows a
9580 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9581 the 8051. Option 'y' for memory summary output file.
9583 Changes to sdcc (All the changes are marked with 'JCF'):
9585 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9587 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9588 overlaying area for it (uses RegBankUsed[4]).
9590 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9591 bank zero as used by default. By default aslink locates the stack
9592 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9593 the creation of the .mem file. Delegates the allocation of data area
9594 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9595 the begining of the stack area to aslink.
9597 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9598 glue() in SDCCglue.c creates an area for it.
9600 2002-09-03 Borut Razem <borut.razem AT siol.net>
9601 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9602 sdcc/src/pic/glue.c:
9603 introduced atexit() handler for teporay files removal in case of
9604 errors, assertions, ...
9606 2002-08-29 Borut Razem <borut.razem AT siol.net>
9607 * sdcc/support/cpp2/auto-host_vc_in.h:
9608 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9609 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9610 Maybe there is a similar problem with BORLANDC? It should be checked!
9612 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9613 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9614 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9615 was not executed, and the compiler (cl) launched a warning:
9616 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9618 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9619 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9621 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9622 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9624 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9625 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9626 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9627 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9628 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9629 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9630 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9631 - added Release configuration in VS projects
9632 - review of compiler an linker options
9633 - VC .exe files are generated in bin_vc directory, not to interfere
9634 with binaries generated from other projects (cygwin, mingw, bcc ...)
9636 * sdcc/src/yacc.dsp: added
9638 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9639 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9640 and insert the version number definitions from .version
9642 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9644 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9645 added - genarate auto-host.h using auto-host_vc_in.h as template
9648 removed from CVS, generated automatically
9650 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9651 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9653 2002-08-11 Borut Razem <borut.razem AT siol.net>
9654 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9656 2002-08-10 Borut Razem <borut.razem AT siol.net>
9657 * src/SDCCmain.c (main):
9658 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9659 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9660 The consequence was that some temporary files were not removed.
9663 unification of code in functions tempfilename() and tempfile():
9664 function tempnam() is defined in Visual Studio 6.0 and .NET
9666 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9668 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9669 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9670 - removed compiler command line option /WX: Treats all warnings as errors
9671 - update a list of source files, included into the project
9673 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9674 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9675 changed project type to Generic Project so that can be correcly converted to VS.NET project
9677 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9679 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9681 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9683 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9684 added return 0 statements after assert() to make compiler happy
9686 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9687 added newline in the def file to keep MSC compiler satisfied
9689 * sdcc/src/z80/gen.c:
9690 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9691 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9692 - solved MSC error in function aopDump()
9694 * sdcc_vc.h: define PREFIX as "\\sdcc"
9696 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9697 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9699 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9700 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9701 - Rewrote the register banking algorithm.
9702 - Added pCode live-range analysis to registers (for now, only non-used and
9703 singly-used registers optimized away)
9705 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9707 * 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.
9709 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9710 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

9734 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9736 2002-03-28 Johan Knol <johan AT balder>
9738 * src/SDCCval.c: fixed bug #532436
9740 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9742 Added "char *Processor" field to the port structure.
9745 Added -p option. Allows port dependent processor to be specified.
9748 Initialized the new field char *Processor field to NULL in all ports
9751 Compiler generated registers for interrupt context saving
9752 were not getting allocated.
9754 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9757 Fixed left shift. Will promote the left side of a left shift
9758 if a) left shifting more than size of operand or b) when assigned
9759 to something size > size of left side
9761 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9763 tons of changes. Register allocation has been
9764 rewritten. Added customization for the various PICs. Flow
9765 analysis is restructured. ...
9771 Added. device.c is a PIC port hack to accomodate variations
9774 2002-03-13 Michael Hope <michaelh AT vroom>
9776 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9869 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9871 * sdcc/src/SDCCloop.c:
9872 Previous fix was not good. basic blocks that have "break" or "return" are
9873 not really partof a loop , but live ranges used in these blocks should
9874 be live thru the entire loop, so set partOfLoop but don't add them to
9877 2002-02-21 <johan AT FRIJA>
9879 * src/SDCCcse.c: fixed bug #514308
9881 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9884 Fixed BUG #519583. If a conditional block ended in a return/break
9885 statement inside a loop, it was not being considered part of the loop.
9887 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9889 2002-02-10 Karl Bongers <karl AT turbobit.com>
9892 Fixed up SDCDB debugger somewhat. Updated debugger/README
9893 with lots of comments and notes.
9895 * device/examples/test2.c:
9896 Fix bug, "red" variable not being initialized(compiler complained).
9898 * device/examples/Makefile, examples/test3.c:
9899 Add Makefile in device/examples folder, compiles test3.c
9900 for use as a multiple module SDCDB test case.
9902 * sim/ucsim/cmd.src/cmdset.cc:
9903 Took out debug printfs in ucsim "next" command.
9906 Karl and Johan start ucsim XA support. Most dissassembly working,
9907 about 75% emulation done(plenty of work remaining).
9909 * sim/ucsim/z80.src:
9910 Add Z80 support to ucsim, add test-ucz80 regression test,
9911 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9947 set preprocessor defines (depending on options)
9949 * src/SDCCicode.c, src/SDCCicode.h:
9950 changes made to handle multiple sends & receives
9953 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
