30 implemented patch 1120823 Thanks to Willy De la Court (normal
31 interrupts need an interrupt number now if they are made critical),
32 and enabled nesting of critical functions though not for gbz80
33 (genCritical, genEndCritical): added functions
34 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
35 * src/z80/mappings.i: added "ei" to all mappings

41 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
42 archive with gcc 4.1 on mips and wrote the patch"
44 2006-03-16 Raphael Neider <rneider AT web.de>
46 * src/pic16/genarith.c (genAddLit): simplified and fixed case where

49 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
52 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
54 * src/.version: increased version number to 2.5.5
55 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
56 linking is done manually in pic16 port's _linkEdit,
57 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
58 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
59 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
60 allocate asmop as AOP_ACC,
61 (aopForRemat): added parameter 'bool result' in function declaration,

74 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
75 call to allocReg, not by manually allocating a new one,
76 (pic16_assignRegisters): now before going through the register
77 allocating functions mark all registers as free. This eliminates some
78 side effects resulting from peephole parser done earlier in the backbone
80 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
82 * src/SDCCicode.c (geniCodeLogic),

138 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
139 which dumps before the function entry point a data byte which represents
140 the number of the local variables used by the specified function, added
141 'xinst' for initial support for Extended Instruction Support,
142 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
143 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
144 port->fun_prefix anymore (may change later),
145 (genFunction, genEndFunction): do not store/restore local registers for
146 _main (this should take care the --main-return command line option in
148 (genOr): removed some legacy pic-port instructions,
149 * src/pic16/genarith.c (genAddLit): re-enabled old code because
150 performing operations with SFR's causes data to be written more than
151 once to each SFR. Perhaps SFRs should be handled in special cases...
152 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
154 * src/pic16/main.c (_process_pragma): stack bound checking did not take
155 into account for stack starting position,
156 (struct OPTIONS pic16_optionsTable): added command line argument
157 --extended or -y for Extended Instruction Support,
158 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
159 (deassignLRs): *** perhaps the most important change, old 'for' code
160 (commented out for reference), didn't account for some registers which
161 were left marked 'not free' after a pointer operation. The change
162 reduces register usage a lot in some cases

2439 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2440 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2441 always available in leading double underscore form. The C99 support is
2442 mostly missing, but it's a start.
2443 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2444 reserved identifier "__data".
2446 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2520 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2522 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2524 * device/lib/printf_large.c: removed inline assembly for portability and
2525 readability. Use printf_fast if speed or size are more important.
2526 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2527 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2529 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2531 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2532 prevent compiler warning
2534 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2536 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2537 moved to level 0 and declared as static. Also they are explicit
2538 placed in access bank. This was necessery because some times they
2539 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2540 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2541 optimizations. Currently only compare to unsigned char is implemented,
2542 * src/pic16/gen.c: added fReturnIdx array,
2543 * (struct resolvedIfx) is moved to gen.h and made public,
2544 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2545 * (aopForSym): added an optimization to directly store in stack of
2546 the operand of a SEND iCode,
2547 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2548 but as registers instead (AOP_REG) using the fReturnIdx array,
2549 * (pic16_freeAsmop): remove the freed register from the
2550 _G.sregsAlloc field,
2551 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2552 a compare of 'WREG',
2553 * (pic16_popGetTempRegCond): changed function prototype, now
2554 function takes also a bitVector argument v which holds the current
2555 set of registers that are allocated for stack access by aopForSym,
2556 registers allocated in aopForSym for accessing stack symbols are not
2557 any more part of the functions usedRegs field,
2558 * (genCall): some times aopOp is called for a stack variable to be
2559 send, aopForSym might perform the push, if this is true make sure
2560 that genCall doesn't push the variable twice by testing _G.resDirect,
2561 * (genFunction): changed testing for unspecified interrupt number
2562 from 256 to INTNO_UNSPEC,
2563 * modified selection scheme of frame pointer generation. Previously
2564 if function did use local registers a frame pointer was generated,
2565 now a frame pointer is generated only if function has arguments
2566 (that need PLUSW2 register access), or has stack arguments, or the
2567 compiler is not instructed to omit the frame pointer,
2568 * (genEndFunction): before restoring local registers that were saved
2569 in the function preamble, also restore the registers that *might*
2570 have been allocated for stack access,
2571 * (genRet): removed some old comments,
2572 * (genCmp, the active (RN's) version): added a call to the
2573 pic16_genCmp_special function to perform the compare with a more
2574 robust and optimized way,
2575 * (genInline): a feature has been added in inline code generation,
2576 which allows a wildcard variable substitution when writing inline
2577 assembly. Code is incomplete and experimental therefore undocumented,
2578 * (genCast): changed order of aopOp for result and right to allow
2579 aopForSym to directly load the result if possible,
2580 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2581 perform an optimized compare on some selected special occasions,
2582 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,

3248 Adding support for replacing ljmps with sjmps in jumptables
3249 generated for switch statements. For now you need to set the
3250 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3251 Now 4 algorithms for mcs51 jumptable generation are used:
3252 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3253 addresses loaded pc-relative for up to 112 cases and stack-pushing
3254 target addresses loaded with offset from dptr for up to 256 cases.

3284 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3286 * added libc directory. The current version of LibC contains string
3287 functions, ctype functions and macros and some functions of the
3288 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3289 be extensively tested in the future. Standard disclaimer here.
3290 Library is not automatically build yet. But one can build it by
3291 invoking 'make' inside the libc directory.

3302 * (pic16_storeForReturn): optimized return of 0,
3303 * (genCmp): experimental code for new genCmp which uses PIC18's
3304 special compare&skip instructions. Initial tests fail some times
3305 with variables grater than 1 byte in size, so new code is disabled,
3306 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3308 * (genCast): began a fix to optimize the casting of a bit to another
3309 bit, now assigning a bitfield to another bitfield will fail, sorry,

3318 and 1 for banking instruction,
3319 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3320 caused stop processing pCodes after a inline assembly block,
3321 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3323 registers when it shouldn't,
3324 * src/pic16/ralloc.c (allocReg): add preliminary support for
3325 supporting a limited set of temporary registers,
3327 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3333 (genFunction): optimize RECEIVE iCodes in reentrant functions
3335 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6335 loaded with the linker search paths (-L arguments) and the libraries
6336 to be linked with the current source (-l arguments). Changes
6337 currently will affect only the pic16 port.
6338 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6339 include path the port specific paths and port specific libraries,
6340 * gplink command now contains the $3 argument,
6341 * src/pic16/device.h,
6342 * src/pic16/device.c,: structure PIC_device is made public and
6343 renamed to PIC16_device, the same for variable Pics which is renamed

6358 Documenting changes from previous commits.
6359 * configure.in (version 1.56),
6360 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6361 when generating output files to configure the pic16 library,
6362 but now I've commented it out, since gputils aren't installed in the
6363 SF compile farm, so library won't compile
6365 * device/lib/Makefile.in (version 1.56): initially I've added in
6366 target 'all' the prerequestive 'model-pic16' so it compiled the
6367 pic16 library, but now I've commented it out for the same reasons
6369 * added targets 'model-pic16' and 'objects-pic16' to compile the
6371 * added target 'port-specific-objects-pic16' to handle the
6372 generated libraries and copy them into the build/ directory
6373 * added target 'clean-intermediate-pic16' to clean intermediate
6374 files into pic16 directory
6375 * in target 'installdirs' added line to create directory pic16 in

6379 added lines to copy all header files to installation path,
6380 * in target 'installdirs' added line create directory for pic16
6381 headers in the installation path

6586 arguments via -W option
6587 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6588 object file from '.rel' to '.o' in port->linker structure,

6620 * src/SDCCast.c (decorateType),
6621 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6622 LEFT_OP (left shift)
6624 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6626 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6627 (default behaviour).
6629 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6631 A python script to validate compiler diagnostic messages. It can be
6632 used to verify that sdcc complains about bad c source code and
6633 gives a good location of the error.
6634 * support/valdiag/Makefile,
6635 * support/valdiag/valdiag.py,
6636 * support/valdiag/tests/*
6638 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6649 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6651 * src/common.h: added ifndef/define/endif macros
6652 around the header file.
6653 Bug reported from Jesus Calvino-Fraga
6655 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6657 * sdcc.spec: updated
6658 * device/include/Makefile.in: don't install CVS directories
6659 * device/lib/Makefile.in: added removal of CVS directories after install
6660 * doc/Makefile: fixed install, added local_icons
6661 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6662 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6663 * src/ds390/gen.c (genRightShift): fixed bug #870788
6664 * src/SDCCast.c (decorateType): fixed bug #870781
6666 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6668 PIC16 port related changes:
6669 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6670 added variable stackPos,
6672 * gen.c: genCall, assignResultValue: added support for
6673 pushing/retrieving function parameters to/from stack,
6674 genFunction,genEndFunction: setup stack frame for the
6676 genAddrOf: will be changed according to bug 863624
6678 * added files genutils.c and genutils.h which contain gen*
6679 debugged and optimised functions extracted from gen.c
6681 * glue.c: added variable 'externs' which holds extern symbols,
6682 pic16emitRegularMap: is modified to properly handle relocatable
6683 symbols under the new scheme,
6684 pic16createInterruptVect: is modified
6685 pic16printPublics: is modified to emit 'global' assembler directives,
6686 added pic16_printExterns to print extern symbols,
6687 pic16glue: initializes stack/frame pointer in the beginning of
6688 the assembly output. Temporary hack, will be corrected later,
6689 because gplink yet does not support stack and SDCC does not
6690 yet support a type of crt0.o object to create the final binary.
6692 * Removed many lines that contain 8051 legacy code.
6693 * The code is finally placed under a 'code' directive.
6694 * Added port specific options.
6696 * _process_pragma: simplified since now we do not need *special*
6697 include file to define SFR registers. But a separate header
6698 will be needed. This will be developed later.
6699 * _pic16_parseOptions: added, parses port specific options:
6700 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6701 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6702 --preplace-udata-with=
6704 * _pic16_setDefaultOptions: modified to initialize section names,
6705 but hack is temporarly out of order since it needs improvement.
6706 * _pic16_genAssemblerPreamble: configuration words are emitted by
6707 their address instead of their name. This part is incomplete and
6708 supports only the 18Fxx2 devices. Other devices will emit an error
6709 during assembly since they do not contain the same set of config
6711 * _pic16_genIVT: is modified,
6713 * pcode.c: added definitions for some hardware registers that are needed
6715 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6716 All PCI entries are updated. Now LFSR is supported.
6717 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6718 * added pic16_newpCodeOpLit2 to support instructions with
6719 two literal arguments
6720 * pic16_pCode2str: corrected code that emits assembler instructions
6721 with two literal operands and those that have an access bit modifier
6722 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6723 this fixes a bug which caused some labels to be lost, when an
6724 assembler directive was added, i.e. banksel,
6725 * pic16_FixRegisterBanking: improved logic that causes the insertion
6727 * InlineFunction: functions that are called once, are not any more
6728 inlined. This can be a port option in the future,
6730 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6732 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6733 hold the corresponding uninitialized symbols,
6734 * pic16_allocProcessorRegister: registers have explicit marked the
6736 * pic16_allocInternalRegister: registers are explicit marked as
6738 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6739 processing list, so bit registers were lost,
6742 * ralloc.h: added field 'accessBank' and original symbol operand
6743 in register definition,
6744 * removed the field isMapped from register definition,
6746 ** Several functions have been removed from various sources:
6747 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6748 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6749 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6750 pic16_assignRelocatableRegisters
6752 ** others have been introduced:
6753 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6754 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6756 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6758 * support/scripts/inc2h.pl: changed definition of BIT_AT
6759 to emit 'sbit at' instead of 'bit at'. This was a request.
6761 PIC16 port related preliminary changes:
6762 * gen.c: prefixed function popRegFromString with
6763 pic16_ and all references to it corrected
6764 * pcode.c: all pic16_pc_* hardware registers prefixed
6765 with underscore (_),
6766 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6767 * ralloc.c: newReg(): when register is REG_SFR then
6768 set address to rIdx,
6769 pic16_allocProcessorRegister(): marks register wasUsed=0
6770 pic16_writeUsedRegs(): added a call to assign processor
6771 registers via pic16_assignFixedRegisters
6773 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6775 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6776 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6777 variables in unused register banks. Also the SSEG is placed
6778 wherever there is enough space for it, and IDATA can be anywhere
6779 in internal RAM. For now compile using -Wl-Y[stack_size].
6780 The mem file is different for this option as well, since it
6781 makes no sense of talking about DSEG lenght.
6783 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6785 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6786 in certain cases, e.g. when ROM assignment, patch provided
6787 from Albert den Haan.
6789 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6932 * src/mcs51/peephole.def,
6933 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7028 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7030 * src/SDCCast.c (decorateType): disabled a transformation I added in
7031 revision 1.188 (access to fields of a structure at an absolute address);
7032 it breaks with bitfields, extern declarations, and gcse analysis.
7033 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7034 could be assigned through a pointer, so don't complain.
7035 * src/SDCCast.c (astErrors),
7037 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7039 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7045 pre-processor macro, i.e. -DMCU=p18f452
7046 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
7047 and modified to handle 'cast' icode similarly to '=' icode

7674 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7675 support for standard C idiom of memory mapped variables; for
7676 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7677 to xdata int at 0x1234 tempvar = 1.

7790 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7791 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7792 fetching of the pointer
7793 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7794 copied from genNearPointerSet()
7795 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7796 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7797 If they pop r0/r1 they must be called in the opposite order than aopOp().
7798 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7799 (resp. --stack-auto), prepared for --xstack

7812 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7813 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7814 type for bits was changed. It resulted in bit variables becoming
7815 global, which is not permitted in PIC 14 assembly output.
7817 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7819 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7832 A few small changes that speed up the peephole optimizer.
7836 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7838 Try to make the peephole optimizer smarter by maintaining
7839 an association between the assembly source code and the
7840 iCodes that originated them. Put this information to use
7841 with a new peephole rule condition "notVolatile" so that
7842 the rules can be aggressive yet still safe.
7847 * src/mcs51/peeph.def
7849 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7853 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7854 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7855 if the left or right operand symbols have the accuse flag set.
7857 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7859 Changed the type of the result of the ! (NOT) operator to char;
7860 previously it returned the same type as the source. This allows
7861 us to eliminate all the genFloatNot functions (all of its target
7862 implementations were very buggy) since !float can use the same

7875 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7876 during interrupts. Ensure WSAVE is located at a shared bank address.
7877 2. Fixed page selection in some places
7878 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7879 the registers name strings.
7880 4. Fixed "signed / unsigned compare" compiler warnings.
7881 5. The PIC port manages its own allocation of the general purpose
7882 registers, but makes no attempt to reuse them. As a result when
7883 compiling it soon runs out of general purpose registers. Some
7884 additional code was added to the files pcode.c and device.c to walk
7885 through the function call tree and rename the registers so that they
7895 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7902 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7904 Made bitfield a distinct type from bit so that bitfields
7905 convert as per ANSI C and bits retain their traditional
7906 boolean style behaviour. Implemented bitfield support in
7914 * src/ds390/gen.c: bit v bitfield split
7915 * src/z80/gen.c: New support for bitfields
7916 * support/regression/tests/bitfields.c: reenabled z80,
7919 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7921 Rules 246.x, 247.x relate to bitfields, the others speed up
7922 access to xdata mapped I/O devices.
7924 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7926 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7928 Cleaned up genPackBits and genUnpackBits and added two helper
7929 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7930 for literal assignments in genPackBits (thanks to Frieder for
7936 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7938 Fixed bug #748310 (pointer to function type mishandled when the
7939 function name is omitted). Also fixed a SIGSEGV when a function
7940 attribute (reentrant, etc) is used on a non-function or on a
7941 function but misplaced before the parameter list.
7943 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7945 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7968 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7970 Made the constant following the "interrupt" keyword optional. If
7971 omitted, the function will not automatically be given an entry
7972 in the interrupt vector table (similar to #pragma NOIV, but
7973 less syntacticly kludgy). The interrupt number is also now
7974 range checked. Also fixed a bug in the high order bit example

8504 added if/endif conditional macros to remove options help
8505 messages from optionsTable when a port is not configured, added
8506 support for the PIc16 port in the ports table, when executing
8507 the compiler with no port specified on command line, a default
8508 port is selected with the new macro DEFAULT_PORT which is
8509 defined in port.h, in setDefaultOptions() linkOptions is removed
8510 from initialization assignment, since now it is a set,
8511 parseCmdLine uses setParseWithComma for linkOptions, in
8512 linkEdit() linkOptions are accessed with new function indexSet()
8513 which returns the i'th item of a set variable. See SDCCset.c, in
8514 linkEdit() when calling buildCmdLine(), added linkOptions as
8515 last argument. Now users can pass arguments to gplink via the
8516 -Wl option, main() uses pic16glue() to glue up pic16 programs

8530 gpasm complaining and test the linkage with gplink, _linkCmd and
8531 _asmCmd changed to be more gplink and gpasm friendly
8532 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8533 produced an error when parsed, peep rule 12 is added to utilize
8534 movff, but it is commented out since the pCode does not support
8535 yet a command with 2 address arguments
8537 2003-05-18 <johan AT balder>
8539 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9572 2003-01-06 <johan AT balder>
9574 * src/SDCCicode.c: fixed array add
9576 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9577 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9578 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9580 2003-01-04 <johan AT balder>
9582 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9584 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9585 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9587 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9588 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9597 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9598 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9600 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9602 * in \sdcc\as\mcs51\ changed these files in order to create an
9603 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9604 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9605 following files to include the previous two files: aslink.dsp,
9606 Makefile.aslink, Makefile.bcc, and Makefile.in.
9608 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9609 .adb instead of .cdb
9611 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9613 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9614 value from option --iram-size.
9616 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9618 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9621 2002-09-18 <wiml AT hhhh.org>
9623 * SDCClrange.h: exposed setFromRange() and setToRange()
9624 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9625 packRegsForAccUse() (bug 542397)
9626 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9627 multiple times and emitting the fetch operations more than once
9628 added aopGetUsesAcc() function to allow binary operators to
9629 fetch their operands in the correct order; made genMinus() emit
9630 compact code for X = LITERAL - Y
9632 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9633 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9634 sprintf() in line 1267.
9636 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9637 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9640 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9641 Changes to aslink (All the changes are marked with 'JCF'):
9643 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9646 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9647 area BSEG. Also moves, if possible, the DATA area down into the internal
9648 ram so more space is available.
9650 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9653 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9654 not bytes. Function summary() which creates a memory usage summary
9655 file with extension .mem. Reports of overlaping stack and small stack
9656 size. If the space for the stack is less than 16 bytes aslink trows a
9659 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9660 the 8051. Option 'y' for memory summary output file.
9662 Changes to sdcc (All the changes are marked with 'JCF'):
9664 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9666 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9667 overlaying area for it (uses RegBankUsed[4]).
9669 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9670 bank zero as used by default. By default aslink locates the stack
9671 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9672 the creation of the .mem file. Delegates the allocation of data area
9673 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9674 the begining of the stack area to aslink.
9676 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9677 glue() in SDCCglue.c creates an area for it.
9679 2002-09-03 Borut Razem <borut.razem AT siol.net>
9680 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9681 sdcc/src/pic/glue.c:
9682 introduced atexit() handler for teporay files removal in case of
9683 errors, assertions, ...
9685 2002-08-29 Borut Razem <borut.razem AT siol.net>
9686 * sdcc/support/cpp2/auto-host_vc_in.h:
9687 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9688 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9689 Maybe there is a similar problem with BORLANDC? It should be checked!
9691 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9692 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9693 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9694 was not executed, and the compiler (cl) launched a warning:
9695 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9697 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9698 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9700 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9701 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9703 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9704 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9705 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9706 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9707 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9708 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9709 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9710 - added Release configuration in VS projects
9711 - review of compiler an linker options
9712 - VC .exe files are generated in bin_vc directory, not to interfere
9713 with binaries generated from other projects (cygwin, mingw, bcc ...)
9715 * sdcc/src/yacc.dsp: added
9717 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9718 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9719 and insert the version number definitions from .version
9721 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9723 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9724 added - genarate auto-host.h using auto-host_vc_in.h as template
9727 removed from CVS, generated automatically
9729 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9730 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9732 2002-08-11 Borut Razem <borut.razem AT siol.net>
9733 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9735 2002-08-10 Borut Razem <borut.razem AT siol.net>
9736 * src/SDCCmain.c (main):
9737 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9738 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9739 The consequence was that some temporary files were not removed.
9742 unification of code in functions tempfilename() and tempfile():
9743 function tempnam() is defined in Visual Studio 6.0 and .NET
9745 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9747 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9748 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9749 - removed compiler command line option /WX: Treats all warnings as errors
9750 - update a list of source files, included into the project
9752 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9753 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9754 changed project type to Generic Project so that can be correcly converted to VS.NET project
9756 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9758 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9760 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9762 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9763 added return 0 statements after assert() to make compiler happy
9765 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9766 added newline in the def file to keep MSC compiler satisfied
9768 * sdcc/src/z80/gen.c:
9769 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9770 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9771 - solved MSC error in function aopDump()
9773 * sdcc_vc.h: define PREFIX as "\\sdcc"
9775 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9776 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9813 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9815 2002-03-28 Johan Knol <johan AT balder>
9817 * src/SDCCval.c: fixed bug #532436
9819 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9821 Added "char *Processor" field to the port structure.
9824 Added -p option. Allows port dependent processor to be specified.
9827 Initialized the new field char *Processor field to NULL in all ports
9830 Compiler generated registers for interrupt context saving
9831 were not getting allocated.
9833 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9836 Fixed left shift. Will promote the left side of a left shift
9837 if a) left shifting more than size of operand or b) when assigned
9838 to something size > size of left side
9840 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9842 tons of changes. Register allocation has been
9843 rewritten. Added customization for the various PICs. Flow
9844 analysis is restructured. ...
9850 Added. device.c is a PIC port hack to accomodate variations
9853 2002-03-13 Michael Hope <michaelh AT vroom>
9855 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9857 2002-03-04 johanknol <johanknol AT manik>
9859 * /src/SDCCval.c: fixed
9861 const unsigned char arr[][2] = { { 0, 1 } };
9862 t18.c:1: error: Initializer element is not constant
9864 2002-03-04 bela <bela AT manik>
9866 * /device/include/mcs51reg.h:
9867 ds89c420 register definition update
9869 2002-03-03 <johan AT FRIJA>

9948 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9950 * sdcc/src/SDCCloop.c:
9951 Previous fix was not good. basic blocks that have "break" or "return" are
9952 not really partof a loop , but live ranges used in these blocks should
9953 be live thru the entire loop, so set partOfLoop but don't add them to
9956 2002-02-21 <johan AT FRIJA>
9958 * src/SDCCcse.c: fixed bug #514308
9960 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9963 Fixed BUG #519583. If a conditional block ended in a return/break
9964 statement inside a loop, it was not being considered part of the loop.
9966 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9968 2002-02-10 Karl Bongers <karl AT turbobit.com>
9971 Fixed up SDCDB debugger somewhat. Updated debugger/README
9972 with lots of comments and notes.
9974 * device/examples/test2.c:
9975 Fix bug, "red" variable not being initialized(compiler complained).
9977 * device/examples/Makefile, examples/test3.c:
9978 Add Makefile in device/examples folder, compiles test3.c
9979 for use as a multiple module SDCDB test case.
9981 * sim/ucsim/cmd.src/cmdset.cc:
9982 Took out debug printfs in ucsim "next" command.
9985 Karl and Johan start ucsim XA support. Most dissassembly working,
9986 about 75% emulation done(plenty of work remaining).
9988 * sim/ucsim/z80.src:
9989 Add Z80 support to ucsim, add test-ucz80 regression test,
9990 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9991 Notice z80 compiler fails on examples/test3.c/crc code.
9993 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
