23 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
24 implemented patch 1120823 Thanks to Willy De la Court (normal
25 interrupts need an interrupt number now if they are made critical),
26 and enabled nesting of critical functions though not for gbz80
27 (genCritical, genEndCritical): added functions
28 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
29 * src/z80/mappings.i: added "ei" to all mappings
31 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
33 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
34 submitted by the Debian SDCC maintainer Aurelien Jarno:
35 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
36 archive with gcc 4.1 on mips and wrote the patch"
38 2006-03-16 Raphael Neider <rneider AT web.de>
40 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
41 the left operand is shorter than the result (c* = lit-c* + int),
43 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
46 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
48 * src/.version: increased version number to 2.5.5
49 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
50 linking is done manually in pic16 port's _linkEdit,
51 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
52 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
53 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
54 allocate asmop as AOP_ACC,
55 (aopForRemat): added parameter 'bool result' in function declaration,
56 (pic16_aopGet): return AOP_ACC when accessing WREG,
57 (pic16_popGetTempReg): minor modification,

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

66 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
68 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
69 call to allocReg, not by manually allocating a new one,
70 (pic16_assignRegisters): now before going through the register
71 allocating functions mark all registers as free. This eliminates some
72 side effects resulting from peephole parser done earlier in the backbone
74 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
76 * src/SDCCicode.c (geniCodeLogic),
77 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

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

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

2514 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2516 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2518 * device/lib/printf_large.c: removed inline assembly for portability and
2519 readability. Use printf_fast if speed or size are more important.
2520 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2521 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2523 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2525 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2526 prevent compiler warning
2528 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2530 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2531 moved to level 0 and declared as static. Also they are explicit
2532 placed in access bank. This was necessery because some times they
2533 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2534 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2535 optimizations. Currently only compare to unsigned char is implemented,
2536 * src/pic16/gen.c: added fReturnIdx array,
2537 * (struct resolvedIfx) is moved to gen.h and made public,
2538 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2539 * (aopForSym): added an optimization to directly store in stack of
2540 the operand of a SEND iCode,
2541 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2542 but as registers instead (AOP_REG) using the fReturnIdx array,
2543 * (pic16_freeAsmop): remove the freed register from the
2544 _G.sregsAlloc field,
2545 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2546 a compare of 'WREG',
2547 * (pic16_popGetTempRegCond): changed function prototype, now
2548 function takes also a bitVector argument v which holds the current
2549 set of registers that are allocated for stack access by aopForSym,
2550 registers allocated in aopForSym for accessing stack symbols are not
2551 any more part of the functions usedRegs field,
2552 * (genCall): some times aopOp is called for a stack variable to be
2553 send, aopForSym might perform the push, if this is true make sure
2554 that genCall doesn't push the variable twice by testing _G.resDirect,
2555 * (genFunction): changed testing for unspecified interrupt number
2556 from 256 to INTNO_UNSPEC,
2557 * modified selection scheme of frame pointer generation. Previously
2558 if function did use local registers a frame pointer was generated,
2559 now a frame pointer is generated only if function has arguments
2560 (that need PLUSW2 register access), or has stack arguments, or the
2561 compiler is not instructed to omit the frame pointer,
2562 * (genEndFunction): before restoring local registers that were saved
2563 in the function preamble, also restore the registers that *might*
2564 have been allocated for stack access,
2565 * (genRet): removed some old comments,
2566 * (genCmp, the active (RN's) version): added a call to the
2567 pic16_genCmp_special function to perform the compare with a more
2568 robust and optimized way,
2569 * (genInline): a feature has been added in inline code generation,
2570 which allows a wildcard variable substitution when writing inline
2571 assembly. Code is incomplete and experimental therefore undocumented,
2572 * (genCast): changed order of aopOp for result and right to allow
2573 aopForSym to directly load the result if possible,
2574 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2575 perform an optimized compare on some selected special occasions,
2576 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2577 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2578 generate an IVT any more,
2579 * src/pic16/main.c (pic16_optionsTable): added command line option
2581 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2582 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2584 * src/pic16/NOTES: Raphael Neider added in list of active developers

3242 Adding support for replacing ljmps with sjmps in jumptables
3243 generated for switch statements. For now you need to set the
3244 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3245 Now 4 algorithms for mcs51 jumptable generation are used:
3246 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3247 addresses loaded pc-relative for up to 112 cases and stack-pushing
3248 target addresses loaded with offset from dptr for up to 256 cases.

3278 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3280 * added libc directory. The current version of LibC contains string
3281 functions, ctype functions and macros and some functions of the
3282 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3283 be extensively tested in the future. Standard disclaimer here.
3284 Library is not automatically build yet. But one can build it by
3285 invoking 'make' inside the libc directory.

3295 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3296 * (pic16_storeForReturn): optimized return of 0,
3297 * (genCmp): experimental code for new genCmp which uses PIC18's
3298 special compare&skip instructions. Initial tests fail some times
3299 with variables grater than 1 byte in size, so new code is disabled,
3300 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3302 * (genCast): began a fix to optimize the casting of a bit to another
3303 bit, now assigning a bitfield to another bitfield will fail, sorry,
3304 * src/pic16/main.c: disabled the use of lr-support feature,
3305 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3311 * (isBankInstruction): modified to return 0 for no banking instruction,
3312 and 1 for banking instruction,
3313 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3314 caused stop processing pCodes after a inline assembly block,
3315 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3316 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3317 registers when it shouldn't,
3318 * src/pic16/ralloc.c (allocReg): add preliminary support for
3319 supporting a limited set of temporary registers,
3321 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3323 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3326 (loadRegFromAop): recognize CLRH optimization,
3327 (genFunction): optimize RECEIVE iCodes in reentrant functions
3329 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3331 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6329 loaded with the linker search paths (-L arguments) and the libraries
6330 to be linked with the current source (-l arguments). Changes
6331 currently will affect only the pic16 port.
6332 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6333 include path the port specific paths and port specific libraries,
6334 * gplink command now contains the $3 argument,
6335 * src/pic16/device.h,

6352 Documenting changes from previous commits.
6353 * configure.in (version 1.56),
6354 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6355 when generating output files to configure the pic16 library,
6356 but now I've commented it out, since gputils aren't installed in the
6357 SF compile farm, so library won't compile
6359 * device/lib/Makefile.in (version 1.56): initially I've added in
6360 target 'all' the prerequestive 'model-pic16' so it compiled the
6361 pic16 library, but now I've commented it out for the same reasons
6363 * added targets 'model-pic16' and 'objects-pic16' to compile the
6365 * added target 'port-specific-objects-pic16' to handle the
6366 generated libraries and copy them into the build/ directory
6367 * added target 'clean-intermediate-pic16' to clean intermediate
6368 files into pic16 directory
6369 * in target 'installdirs' added line to create directory pic16 in

6373 added lines to copy all header files to installation path,
6374 * in target 'installdirs' added line create directory for pic16
6375 headers in the installation path

6615 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6616 LEFT_OP (left shift)
6618 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6620 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6621 (default behaviour).
6623 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6625 A python script to validate compiler diagnostic messages. It can be
6626 used to verify that sdcc complains about bad c source code and
6627 gives a good location of the error.
6628 * support/valdiag/Makefile,
6629 * support/valdiag/valdiag.py,
6630 * support/valdiag/tests/*

6647 Bug reported from Jesus Calvino-Fraga
6649 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6651 * sdcc.spec: updated
6652 * device/include/Makefile.in: don't install CVS directories
6653 * device/lib/Makefile.in: added removal of CVS directories after install
6654 * doc/Makefile: fixed install, added local_icons
6655 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6656 * src/mcs51/gen.c (genRightShift): fixed bug #870788

6660 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6662 PIC16 port related changes:
6663 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6664 added variable stackPos,
6666 * gen.c: genCall, assignResultValue: added support for
6667 pushing/retrieving function parameters to/from stack,
6668 genFunction,genEndFunction: setup stack frame for the
6670 genAddrOf: will be changed according to bug 863624
6672 * added files genutils.c and genutils.h which contain gen*
6673 debugged and optimised functions extracted from gen.c
6675 * glue.c: added variable 'externs' which holds extern symbols,
6676 pic16emitRegularMap: is modified to properly handle relocatable
6677 symbols under the new scheme,
6678 pic16createInterruptVect: is modified
6679 pic16printPublics: is modified to emit 'global' assembler directives,
6680 added pic16_printExterns to print extern symbols,
6681 pic16glue: initializes stack/frame pointer in the beginning of
6682 the assembly output. Temporary hack, will be corrected later,
6683 because gplink yet does not support stack and SDCC does not
6684 yet support a type of crt0.o object to create the final binary.
6686 * Removed many lines that contain 8051 legacy code.
6687 * The code is finally placed under a 'code' directive.
6688 * Added port specific options.
6690 * _process_pragma: simplified since now we do not need *special*
6691 include file to define SFR registers. But a separate header
6692 will be needed. This will be developed later.
6693 * _pic16_parseOptions: added, parses port specific options:
6694 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6695 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6696 --preplace-udata-with=
6698 * _pic16_setDefaultOptions: modified to initialize section names,
6699 but hack is temporarly out of order since it needs improvement.
6700 * _pic16_genAssemblerPreamble: configuration words are emitted by
6701 their address instead of their name. This part is incomplete and
6702 supports only the 18Fxx2 devices. Other devices will emit an error
6703 during assembly since they do not contain the same set of config
6705 * _pic16_genIVT: is modified,
6707 * pcode.c: added definitions for some hardware registers that are needed
6709 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6710 All PCI entries are updated. Now LFSR is supported.
6711 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6712 * added pic16_newpCodeOpLit2 to support instructions with
6713 two literal arguments
6714 * pic16_pCode2str: corrected code that emits assembler instructions
6715 with two literal operands and those that have an access bit modifier
6716 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6717 this fixes a bug which caused some labels to be lost, when an
6718 assembler directive was added, i.e. banksel,
6719 * pic16_FixRegisterBanking: improved logic that causes the insertion
6721 * InlineFunction: functions that are called once, are not any more
6722 inlined. This can be a port option in the future,
6724 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6726 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6727 hold the corresponding uninitialized symbols,
6728 * pic16_allocProcessorRegister: registers have explicit marked the
6730 * pic16_allocInternalRegister: registers are explicit marked as
6732 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6733 processing list, so bit registers were lost,
6736 * ralloc.h: added field 'accessBank' and original symbol operand
6737 in register definition,
6738 * removed the field isMapped from register definition,
6740 ** Several functions have been removed from various sources:
6741 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6742 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6743 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6744 pic16_assignRelocatableRegisters
6746 ** others have been introduced:
6747 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6748 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6750 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6752 * support/scripts/inc2h.pl: changed definition of BIT_AT
6753 to emit 'sbit at' instead of 'bit at'. This was a request.
6755 PIC16 port related preliminary changes:
6756 * gen.c: prefixed function popRegFromString with
6757 pic16_ and all references to it corrected
6758 * pcode.c: all pic16_pc_* hardware registers prefixed
6759 with underscore (_),
6760 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6761 * ralloc.c: newReg(): when register is REG_SFR then
6762 set address to rIdx,
6763 pic16_allocProcessorRegister(): marks register wasUsed=0
6764 pic16_writeUsedRegs(): added a call to assign processor
6765 registers via pic16_assignFixedRegisters
6767 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6769 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6770 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6771 variables in unused register banks. Also the SSEG is placed
6772 wherever there is enough space for it, and IDATA can be anywhere
6773 in internal RAM. For now compile using -Wl-Y[stack_size].
6774 The mem file is different for this option as well, since it
6775 makes no sense of talking about DSEG lenght.
6777 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6779 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6780 in certain cases, e.g. when ROM assignment, patch provided
6781 from Albert den Haan.
6783 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6926 * src/mcs51/peephole.def,
6927 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7022 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7024 * src/SDCCast.c (decorateType): disabled a transformation I added in
7025 revision 1.188 (access to fields of a structure at an absolute address);
7026 it breaks with bitfields, extern declarations, and gcse analysis.
7027 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7028 could be assigned through a pointer, so don't complain.
7029 * src/SDCCast.c (astErrors),
7031 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7668 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7669 support for standard C idiom of memory mapped variables; for
7670 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7671 to xdata int at 0x1234 tempvar = 1.
7672 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7673 provided by Akiya ISHIDA

7689 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7691 Fixed bug #621531 (const & volatile confusion in the type chain).
7692 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7784 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7785 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7786 fetching of the pointer
7787 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7788 copied from genNearPointerSet()
7789 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7790 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7791 If they pop r0/r1 they must be called in the opposite order than aopOp().
7792 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7793 (resp. --stack-auto), prepared for --xstack

7804 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7806 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7807 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7808 type for bits was changed. It resulted in bit variables becoming
7809 global, which is not permitted in PIC 14 assembly output.
7811 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7813 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7826 A few small changes that speed up the peephole optimizer.
7830 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7832 Try to make the peephole optimizer smarter by maintaining
7833 an association between the assembly source code and the
7834 iCodes that originated them. Put this information to use
7835 with a new peephole rule condition "notVolatile" so that
7836 the rules can be aggressive yet still safe.
7841 * src/mcs51/peeph.def
7843 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7847 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7848 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7849 if the left or right operand symbols have the accuse flag set.
7851 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7853 Changed the type of the result of the ! (NOT) operator to char;
7854 previously it returned the same type as the source. This allows
7855 us to eliminate all the genFloatNot functions (all of its target
7856 implementations were very buggy) since !float can use the same

7868 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7869 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7870 during interrupts. Ensure WSAVE is located at a shared bank address.
7871 2. Fixed page selection in some places
7872 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7873 the registers name strings.
7874 4. Fixed "signed / unsigned compare" compiler warnings.
7875 5. The PIC port manages its own allocation of the general purpose
7876 registers, but makes no attempt to reuse them. As a result when
7877 compiling it soon runs out of general purpose registers. Some
7878 additional code was added to the files pcode.c and device.c to walk
7879 through the function call tree and rename the registers so that they
7889 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7890 genPlus() & genMinus() when the result is the same as left or right

7896 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7898 Made bitfield a distinct type from bit so that bitfields
7899 convert as per ANSI C and bits retain their traditional
7900 boolean style behaviour. Implemented bitfield support in
7908 * src/ds390/gen.c: bit v bitfield split
7909 * src/z80/gen.c: New support for bitfields
7910 * support/regression/tests/bitfields.c: reenabled z80,
7913 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7915 Rules 246.x, 247.x relate to bitfields, the others speed up
7916 access to xdata mapped I/O devices.
7918 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7920 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7922 Cleaned up genPackBits and genUnpackBits and added two helper
7923 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7924 for literal assignments in genPackBits (thanks to Frieder for
7930 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7932 Fixed bug #748310 (pointer to function type mishandled when the
7933 function name is omitted). Also fixed a SIGSEGV when a function
7934 attribute (reentrant, etc) is used on a non-function or on a
7935 function but misplaced before the parameter list.
7937 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7939 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7940 * support/Util/SDCCerr.h,

7962 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7964 Made the constant following the "interrupt" keyword optional. If
7965 omitted, the function will not automatically be given an entry
7966 in the interrupt vector table (similar to #pragma NOIV, but
7967 less syntacticly kludgy). The interrupt number is also now
7968 range checked. Also fixed a bug in the high order bit example

7982 * src/SDCCicode.c (operandOperation): rewritten some ops
7983 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7984 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7986 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7987 be re-activated by defining REDUCE_LITERALS)
7988 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7989 unsigned, but are signed by default
7990 * src/SDCCval.c (constVal): rearranged
7991 * src/SDCCval.c (valMod): preliminary fix
7992 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8498 added if/endif conditional macros to remove options help
8499 messages from optionsTable when a port is not configured, added
8500 support for the PIc16 port in the ports table, when executing
8501 the compiler with no port specified on command line, a default
8502 port is selected with the new macro DEFAULT_PORT which is
8503 defined in port.h, in setDefaultOptions() linkOptions is removed
8504 from initialization assignment, since now it is a set,
8505 parseCmdLine uses setParseWithComma for linkOptions, in
8506 linkEdit() linkOptions are accessed with new function indexSet()
8507 which returns the i'th item of a set variable. See SDCCset.c, in
8508 linkEdit() when calling buildCmdLine(), added linkOptions as
8509 last argument. Now users can pass arguments to gplink via the
8510 -Wl option, main() uses pic16glue() to glue up pic16 programs

8524 gpasm complaining and test the linkage with gplink, _linkCmd and
8525 _asmCmd changed to be more gplink and gpasm friendly
8526 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8527 produced an error when parsed, peep rule 12 is added to utilize
8528 movff, but it is commented out since the pCode does not support
8529 yet a command with 2 address arguments
8531 2003-05-18 <johan AT balder>
8533 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8560 2003-05-11 Borut Razem <borut.razem AT siol.net>
8562 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9548 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9549 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9551 2003-01-07 <johan AT balder>
9553 * src/SDCCast.c (decorateType): fixed bug #600035
9555 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9556 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9566 2003-01-06 <johan AT balder>
9568 * src/SDCCicode.c: fixed array add
9570 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9571 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9572 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9574 2003-01-04 <johan AT balder>
9576 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9578 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9579 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9581 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9582 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9583 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9585 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9586 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9588 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9589 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9591 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9592 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9594 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9596 * in \sdcc\as\mcs51\ changed these files in order to create an
9597 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9598 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9599 following files to include the previous two files: aslink.dsp,
9600 Makefile.aslink, Makefile.bcc, and Makefile.in.
9602 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9603 .adb instead of .cdb
9605 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9607 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9608 value from option --iram-size.
9610 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9612 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9615 2002-09-18 <wiml AT hhhh.org>
9617 * SDCClrange.h: exposed setFromRange() and setToRange()
9618 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9619 packRegsForAccUse() (bug 542397)
9620 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9621 multiple times and emitting the fetch operations more than once
9622 added aopGetUsesAcc() function to allow binary operators to
9623 fetch their operands in the correct order; made genMinus() emit
9624 compact code for X = LITERAL - Y
9626 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9627 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9628 sprintf() in line 1267.
9630 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9631 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9634 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9635 Changes to aslink (All the changes are marked with 'JCF'):
9637 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9640 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9641 area BSEG. Also moves, if possible, the DATA area down into the internal
9642 ram so more space is available.
9644 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9647 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9648 not bytes. Function summary() which creates a memory usage summary
9649 file with extension .mem. Reports of overlaping stack and small stack
9650 size. If the space for the stack is less than 16 bytes aslink trows a
9653 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9654 the 8051. Option 'y' for memory summary output file.
9656 Changes to sdcc (All the changes are marked with 'JCF'):
9658 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9660 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9661 overlaying area for it (uses RegBankUsed[4]).
9663 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9664 bank zero as used by default. By default aslink locates the stack
9665 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9666 the creation of the .mem file. Delegates the allocation of data area
9667 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9668 the begining of the stack area to aslink.
9670 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9671 glue() in SDCCglue.c creates an area for it.
9673 2002-09-03 Borut Razem <borut.razem AT siol.net>
9674 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9675 sdcc/src/pic/glue.c:
9676 introduced atexit() handler for teporay files removal in case of
9677 errors, assertions, ...
9679 2002-08-29 Borut Razem <borut.razem AT siol.net>
9680 * sdcc/support/cpp2/auto-host_vc_in.h:
9681 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9682 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9683 Maybe there is a similar problem with BORLANDC? It should be checked!
9685 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9686 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9687 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9688 was not executed, and the compiler (cl) launched a warning:
9689 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9691 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9692 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9694 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9695 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9697 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9698 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9699 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9700 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9701 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9702 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9703 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9704 - added Release configuration in VS projects
9705 - review of compiler an linker options
9706 - VC .exe files are generated in bin_vc directory, not to interfere
9707 with binaries generated from other projects (cygwin, mingw, bcc ...)
9709 * sdcc/src/yacc.dsp: added
9711 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9712 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9713 and insert the version number definitions from .version
9715 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9717 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9718 added - genarate auto-host.h using auto-host_vc_in.h as template
9721 removed from CVS, generated automatically
9723 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9724 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9726 2002-08-11 Borut Razem <borut.razem AT siol.net>
9727 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9729 2002-08-10 Borut Razem <borut.razem AT siol.net>
9730 * src/SDCCmain.c (main):
9731 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9732 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9733 The consequence was that some temporary files were not removed.
9736 unification of code in functions tempfilename() and tempfile():
9737 function tempnam() is defined in Visual Studio 6.0 and .NET
9739 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9741 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9742 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9743 - removed compiler command line option /WX: Treats all warnings as errors
9744 - update a list of source files, included into the project
9746 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9747 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9748 changed project type to Generic Project so that can be correcly converted to VS.NET project
9750 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9752 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9754 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9756 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9757 added return 0 statements after assert() to make compiler happy
9759 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9760 added newline in the def file to keep MSC compiler satisfied
9762 * sdcc/src/z80/gen.c:
9763 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9764 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9765 - solved MSC error in function aopDump()
9767 * sdcc_vc.h: define PREFIX as "\\sdcc"
9769 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9770 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9773 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9774 - Rewrote the register banking algorithm.
9775 - Added pCode live-range analysis to registers (for now, only non-used and
9776 singly-used registers optimized away)
9778 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9780 * 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.

9805 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9807 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9809 2002-03-28 Johan Knol <johan AT balder>
9811 * src/SDCCval.c: fixed bug #532436
9813 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9815 Added "char *Processor" field to the port structure.
9818 Added -p option. Allows port dependent processor to be specified.
9821 Initialized the new field char *Processor field to NULL in all ports
9824 Compiler generated registers for interrupt context saving
9825 were not getting allocated.
9827 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9830 Fixed left shift. Will promote the left side of a left shift
9831 if a) left shifting more than size of operand or b) when assigned
9832 to something size > size of left side
9834 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9836 tons of changes. Register allocation has been
9837 rewritten. Added customization for the various PICs. Flow
9838 analysis is restructured. ...
9844 Added. device.c is a PIC port hack to accomodate variations
9847 2002-03-13 Michael Hope <michaelh AT vroom>
9849 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9851 2002-03-04 johanknol <johanknol AT manik>
9853 * /src/SDCCval.c: fixed
9855 const unsigned char arr[][2] = { { 0, 1 } };
9856 t18.c:1: error: Initializer element is not constant
9858 2002-03-04 bela <bela AT manik>
9860 * /device/include/mcs51reg.h:
9861 ds89c420 register definition update
9863 2002-03-03 <johan AT FRIJA>

9942 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9944 * sdcc/src/SDCCloop.c:
9945 Previous fix was not good. basic blocks that have "break" or "return" are
9946 not really partof a loop , but live ranges used in these blocks should
9947 be live thru the entire loop, so set partOfLoop but don't add them to
9950 2002-02-21 <johan AT FRIJA>
9952 * src/SDCCcse.c: fixed bug #514308
9954 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9957 Fixed BUG #519583. If a conditional block ended in a return/break
9958 statement inside a loop, it was not being considered part of the loop.
9960 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9962 2002-02-10 Karl Bongers <karl AT turbobit.com>
9965 Fixed up SDCDB debugger somewhat. Updated debugger/README
9966 with lots of comments and notes.
9968 * device/examples/test2.c:
9969 Fix bug, "red" variable not being initialized(compiler complained).
9971 * device/examples/Makefile, examples/test3.c:
9972 Add Makefile in device/examples folder, compiles test3.c
9973 for use as a multiple module SDCDB test case.
9975 * sim/ucsim/cmd.src/cmdset.cc:
9976 Took out debug printfs in ucsim "next" command.
9979 Karl and Johan start ucsim XA support. Most dissassembly working,
9980 about 75% emulation done(plenty of work remaining).
9982 * sim/ucsim/z80.src:
9983 Add Z80 support to ucsim, add test-ucz80 regression test,
9984 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9985 Notice z80 compiler fails on examples/test3.c/crc code.
9987 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9989 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
9990 Added support for --parms-in-bank1
9992 * src/ds390/peeph.def:
9993 added a few more peephole optimzations
9996 1) added __builtin_inp & __builtin_outp used to read in data of given length
9997 from a memory mapped port
9998 2) added __builtin_memcmp
9999 3) added __builtin_swapw swap bytes of a short
10001 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10002 1) handle multiple send & receives from register bank1
10003 2) ralloc can now allocate DPTR1 to some liveRanges
10005 * src/SDCCsymt.c, src/SDCCsymt.h:
10006 changes to handle multiple sends & receives
10008 * src/SDCCptropt.h:
10009 added some pointer arithmetic optimization
10011 * src/SDCCptropt.c:
10012 added some pointer arithmetic optimizations but not stable yet so not
10013 called from anywhere (will get this working shortly)
10015 * src/SDCCopt.c: fixed for multiple sends & receives
10018 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
