19 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
20 implemented patch 1120823 Thanks to Willy De la Court (normal
21 interrupts need an interrupt number now if they are made critical),
22 and enabled nesting of critical functions though not for gbz80
23 (genCritical, genEndCritical): added functions
24 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
25 * src/z80/mappings.i: added "ei" to all mappings
27 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
29 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
30 submitted by the Debian SDCC maintainer Aurelien Jarno:
31 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
32 archive with gcc 4.1 on mips and wrote the patch"
34 2006-03-16 Raphael Neider <rneider AT web.de>
36 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
37 the left operand is shorter than the result (c* = lit-c* + int),
39 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
42 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
44 * src/.version: increased version number to 2.5.5
45 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
46 linking is done manually in pic16 port's _linkEdit,
47 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
48 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
49 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
50 allocate asmop as AOP_ACC,
51 (aopForRemat): added parameter 'bool result' in function declaration,
52 (pic16_aopGet): return AOP_ACC when accessing WREG,
53 (pic16_popGetTempReg): minor modification,

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

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

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

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

2510 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2512 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2514 * device/lib/printf_large.c: removed inline assembly for portability and
2515 readability. Use printf_fast if speed or size are more important.
2516 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2517 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2519 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2521 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2522 prevent compiler warning
2524 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2526 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2527 moved to level 0 and declared as static. Also they are explicit
2528 placed in access bank. This was necessery because some times they
2529 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2530 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2531 optimizations. Currently only compare to unsigned char is implemented,
2532 * src/pic16/gen.c: added fReturnIdx array,
2533 * (struct resolvedIfx) is moved to gen.h and made public,
2534 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2535 * (aopForSym): added an optimization to directly store in stack of
2536 the operand of a SEND iCode,
2537 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2538 but as registers instead (AOP_REG) using the fReturnIdx array,
2539 * (pic16_freeAsmop): remove the freed register from the
2540 _G.sregsAlloc field,
2541 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2542 a compare of 'WREG',
2543 * (pic16_popGetTempRegCond): changed function prototype, now
2544 function takes also a bitVector argument v which holds the current
2545 set of registers that are allocated for stack access by aopForSym,
2546 registers allocated in aopForSym for accessing stack symbols are not
2547 any more part of the functions usedRegs field,
2548 * (genCall): some times aopOp is called for a stack variable to be
2549 send, aopForSym might perform the push, if this is true make sure
2550 that genCall doesn't push the variable twice by testing _G.resDirect,
2551 * (genFunction): changed testing for unspecified interrupt number
2552 from 256 to INTNO_UNSPEC,
2553 * modified selection scheme of frame pointer generation. Previously
2554 if function did use local registers a frame pointer was generated,
2555 now a frame pointer is generated only if function has arguments
2556 (that need PLUSW2 register access), or has stack arguments, or the
2557 compiler is not instructed to omit the frame pointer,
2558 * (genEndFunction): before restoring local registers that were saved
2559 in the function preamble, also restore the registers that *might*
2560 have been allocated for stack access,
2561 * (genRet): removed some old comments,
2562 * (genCmp, the active (RN's) version): added a call to the
2563 pic16_genCmp_special function to perform the compare with a more
2564 robust and optimized way,
2565 * (genInline): a feature has been added in inline code generation,
2566 which allows a wildcard variable substitution when writing inline
2567 assembly. Code is incomplete and experimental therefore undocumented,
2568 * (genCast): changed order of aopOp for result and right to allow
2569 aopForSym to directly load the result if possible,
2570 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2571 perform an optimized compare on some selected special occasions,
2572 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2573 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2574 generate an IVT any more,
2575 * src/pic16/main.c (pic16_optionsTable): added command line option
2577 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2578 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2580 * src/pic16/NOTES: Raphael Neider added in list of active developers
2581 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and

3238 Adding support for replacing ljmps with sjmps in jumptables
3239 generated for switch statements. For now you need to set the
3240 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3241 Now 4 algorithms for mcs51 jumptable generation are used:
3242 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3243 addresses loaded pc-relative for up to 112 cases and stack-pushing
3244 target addresses loaded with offset from dptr for up to 256 cases.

3274 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3276 * added libc directory. The current version of LibC contains string
3277 functions, ctype functions and macros and some functions of the
3278 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3279 be extensively tested in the future. Standard disclaimer here.
3280 Library is not automatically build yet. But one can build it by
3281 invoking 'make' inside the libc directory.

3292 * (pic16_storeForReturn): optimized return of 0,
3293 * (genCmp): experimental code for new genCmp which uses PIC18's
3294 special compare&skip instructions. Initial tests fail some times
3295 with variables grater than 1 byte in size, so new code is disabled,
3296 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3298 * (genCast): began a fix to optimize the casting of a bit to another
3299 bit, now assigning a bitfield to another bitfield will fail, sorry,

3308 and 1 for banking instruction,
3309 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3310 caused stop processing pCodes after a inline assembly block,
3311 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3313 registers when it shouldn't,
3314 * src/pic16/ralloc.c (allocReg): add preliminary support for
3315 supporting a limited set of temporary registers,
3317 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3323 (genFunction): optimize RECEIVE iCodes in reentrant functions
3325 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6325 loaded with the linker search paths (-L arguments) and the libraries
6326 to be linked with the current source (-l arguments). Changes
6327 currently will affect only the pic16 port.
6328 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6329 include path the port specific paths and port specific libraries,
6330 * gplink command now contains the $3 argument,
6331 * src/pic16/device.h,

6348 Documenting changes from previous commits.
6349 * configure.in (version 1.56),
6350 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6351 when generating output files to configure the pic16 library,
6352 but now I've commented it out, since gputils aren't installed in the
6353 SF compile farm, so library won't compile
6355 * device/lib/Makefile.in (version 1.56): initially I've added in
6356 target 'all' the prerequestive 'model-pic16' so it compiled the
6357 pic16 library, but now I've commented it out for the same reasons
6359 * added targets 'model-pic16' and 'objects-pic16' to compile the
6361 * added target 'port-specific-objects-pic16' to handle the
6362 generated libraries and copy them into the build/ directory
6363 * added target 'clean-intermediate-pic16' to clean intermediate
6364 files into pic16 directory
6365 * in target 'installdirs' added line to create directory pic16 in

6369 added lines to copy all header files to installation path,
6370 * in target 'installdirs' added line create directory for pic16
6371 headers in the installation path

6611 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6612 LEFT_OP (left shift)
6614 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6616 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6617 (default behaviour).
6619 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6621 A python script to validate compiler diagnostic messages. It can be
6622 used to verify that sdcc complains about bad c source code and
6623 gives a good location of the error.
6624 * support/valdiag/Makefile,
6625 * support/valdiag/valdiag.py,
6626 * support/valdiag/tests/*

6639 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6641 * src/common.h: added ifndef/define/endif macros
6642 around the header file.
6643 Bug reported from Jesus Calvino-Fraga
6645 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6647 * sdcc.spec: updated
6648 * device/include/Makefile.in: don't install CVS directories
6649 * device/lib/Makefile.in: added removal of CVS directories after install
6650 * doc/Makefile: fixed install, added local_icons
6651 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6652 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6653 * src/ds390/gen.c (genRightShift): fixed bug #870788
6654 * src/SDCCast.c (decorateType): fixed bug #870781
6656 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6658 PIC16 port related changes:
6659 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6660 added variable stackPos,
6662 * gen.c: genCall, assignResultValue: added support for
6663 pushing/retrieving function parameters to/from stack,
6664 genFunction,genEndFunction: setup stack frame for the
6666 genAddrOf: will be changed according to bug 863624
6668 * added files genutils.c and genutils.h which contain gen*
6669 debugged and optimised functions extracted from gen.c
6671 * glue.c: added variable 'externs' which holds extern symbols,
6672 pic16emitRegularMap: is modified to properly handle relocatable
6673 symbols under the new scheme,
6674 pic16createInterruptVect: is modified
6675 pic16printPublics: is modified to emit 'global' assembler directives,
6676 added pic16_printExterns to print extern symbols,
6677 pic16glue: initializes stack/frame pointer in the beginning of
6678 the assembly output. Temporary hack, will be corrected later,
6679 because gplink yet does not support stack and SDCC does not
6680 yet support a type of crt0.o object to create the final binary.
6682 * Removed many lines that contain 8051 legacy code.
6683 * The code is finally placed under a 'code' directive.
6684 * Added port specific options.
6686 * _process_pragma: simplified since now we do not need *special*
6687 include file to define SFR registers. But a separate header
6688 will be needed. This will be developed later.
6689 * _pic16_parseOptions: added, parses port specific options:
6690 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6691 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6692 --preplace-udata-with=
6694 * _pic16_setDefaultOptions: modified to initialize section names,
6695 but hack is temporarly out of order since it needs improvement.
6696 * _pic16_genAssemblerPreamble: configuration words are emitted by
6697 their address instead of their name. This part is incomplete and
6698 supports only the 18Fxx2 devices. Other devices will emit an error
6699 during assembly since they do not contain the same set of config
6701 * _pic16_genIVT: is modified,
6703 * pcode.c: added definitions for some hardware registers that are needed
6705 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6706 All PCI entries are updated. Now LFSR is supported.
6707 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6708 * added pic16_newpCodeOpLit2 to support instructions with
6709 two literal arguments
6710 * pic16_pCode2str: corrected code that emits assembler instructions
6711 with two literal operands and those that have an access bit modifier
6712 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6713 this fixes a bug which caused some labels to be lost, when an
6714 assembler directive was added, i.e. banksel,
6715 * pic16_FixRegisterBanking: improved logic that causes the insertion
6717 * InlineFunction: functions that are called once, are not any more
6718 inlined. This can be a port option in the future,
6720 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6722 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6723 hold the corresponding uninitialized symbols,
6724 * pic16_allocProcessorRegister: registers have explicit marked the
6726 * pic16_allocInternalRegister: registers are explicit marked as
6728 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6729 processing list, so bit registers were lost,
6732 * ralloc.h: added field 'accessBank' and original symbol operand
6733 in register definition,
6734 * removed the field isMapped from register definition,
6736 ** Several functions have been removed from various sources:
6737 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6738 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6739 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6740 pic16_assignRelocatableRegisters
6742 ** others have been introduced:
6743 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6744 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6746 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6748 * support/scripts/inc2h.pl: changed definition of BIT_AT
6749 to emit 'sbit at' instead of 'bit at'. This was a request.
6751 PIC16 port related preliminary changes:
6752 * gen.c: prefixed function popRegFromString with
6753 pic16_ and all references to it corrected
6754 * pcode.c: all pic16_pc_* hardware registers prefixed
6755 with underscore (_),
6756 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6757 * ralloc.c: newReg(): when register is REG_SFR then
6758 set address to rIdx,
6759 pic16_allocProcessorRegister(): marks register wasUsed=0
6760 pic16_writeUsedRegs(): added a call to assign processor
6761 registers via pic16_assignFixedRegisters
6763 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6765 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6766 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6767 variables in unused register banks. Also the SSEG is placed
6768 wherever there is enough space for it, and IDATA can be anywhere
6769 in internal RAM. For now compile using -Wl-Y[stack_size].
6770 The mem file is different for this option as well, since it
6771 makes no sense of talking about DSEG lenght.
6773 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6775 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6776 in certain cases, e.g. when ROM assignment, patch provided
6777 from Albert den Haan.
6779 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6922 * src/mcs51/peephole.def,
6923 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6924 (allows non-interrupt and interrupt code to safely compete for a resource

7018 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7020 * src/SDCCast.c (decorateType): disabled a transformation I added in
7021 revision 1.188 (access to fields of a structure at an absolute address);
7022 it breaks with bitfields, extern declarations, and gcse analysis.
7023 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7024 could be assigned through a pointer, so don't complain.
7025 * src/SDCCast.c (astErrors),
7027 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7664 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7665 support for standard C idiom of memory mapped variables; for
7666 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7667 to xdata int at 0x1234 tempvar = 1.
7668 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7669 provided by Akiya ISHIDA

7685 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7687 Fixed bug #621531 (const & volatile confusion in the type chain).
7688 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7780 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7781 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7782 fetching of the pointer
7783 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7784 copied from genNearPointerSet()
7785 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7786 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7787 If they pop r0/r1 they must be called in the opposite order than aopOp().
7788 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7789 (resp. --stack-auto), prepared for --xstack

7800 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7802 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7803 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7804 type for bits was changed. It resulted in bit variables becoming
7805 global, which is not permitted in PIC 14 assembly output.
7807 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7809 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7822 A few small changes that speed up the peephole optimizer.
7826 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7828 Try to make the peephole optimizer smarter by maintaining
7829 an association between the assembly source code and the
7830 iCodes that originated them. Put this information to use
7831 with a new peephole rule condition "notVolatile" so that
7832 the rules can be aggressive yet still safe.
7837 * src/mcs51/peeph.def
7839 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7843 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7844 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7845 if the left or right operand symbols have the accuse flag set.
7847 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7849 Changed the type of the result of the ! (NOT) operator to char;
7850 previously it returned the same type as the source. This allows
7851 us to eliminate all the genFloatNot functions (all of its target
7852 implementations were very buggy) since !float can use the same

7864 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7865 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7866 during interrupts. Ensure WSAVE is located at a shared bank address.
7867 2. Fixed page selection in some places
7868 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7869 the registers name strings.
7870 4. Fixed "signed / unsigned compare" compiler warnings.
7871 5. The PIC port manages its own allocation of the general purpose
7872 registers, but makes no attempt to reuse them. As a result when
7873 compiling it soon runs out of general purpose registers. Some
7874 additional code was added to the files pcode.c and device.c to walk
7875 through the function call tree and rename the registers so that they
7885 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7886 genPlus() & genMinus() when the result is the same as left or right

7892 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7894 Made bitfield a distinct type from bit so that bitfields
7895 convert as per ANSI C and bits retain their traditional
7896 boolean style behaviour. Implemented bitfield support in
7904 * src/ds390/gen.c: bit v bitfield split
7905 * src/z80/gen.c: New support for bitfields
7906 * support/regression/tests/bitfields.c: reenabled z80,
7909 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7911 Rules 246.x, 247.x relate to bitfields, the others speed up
7912 access to xdata mapped I/O devices.
7914 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7916 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7918 Cleaned up genPackBits and genUnpackBits and added two helper
7919 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7920 for literal assignments in genPackBits (thanks to Frieder for
7926 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7928 Fixed bug #748310 (pointer to function type mishandled when the
7929 function name is omitted). Also fixed a SIGSEGV when a function
7930 attribute (reentrant, etc) is used on a non-function or on a
7931 function but misplaced before the parameter list.
7933 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7935 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7936 * support/Util/SDCCerr.h,

7958 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7960 Made the constant following the "interrupt" keyword optional. If
7961 omitted, the function will not automatically be given an entry
7962 in the interrupt vector table (similar to #pragma NOIV, but
7963 less syntacticly kludgy). The interrupt number is also now
7964 range checked. Also fixed a bug in the high order bit example

7979 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7980 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7982 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7983 be re-activated by defining REDUCE_LITERALS)
7984 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7985 unsigned, but are signed by default
7986 * src/SDCCval.c (constVal): rearranged
7987 * src/SDCCval.c (valMod): preliminary fix
7988 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8030 constants are unsigned; added recognition of "u" flag for unsigned
8031 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8032 * src/SDCCval.c (valDiv, valMod): fixed signdness

8494 added if/endif conditional macros to remove options help
8495 messages from optionsTable when a port is not configured, added
8496 support for the PIc16 port in the ports table, when executing
8497 the compiler with no port specified on command line, a default
8498 port is selected with the new macro DEFAULT_PORT which is
8499 defined in port.h, in setDefaultOptions() linkOptions is removed
8500 from initialization assignment, since now it is a set,
8501 parseCmdLine uses setParseWithComma for linkOptions, in
8502 linkEdit() linkOptions are accessed with new function indexSet()
8503 which returns the i'th item of a set variable. See SDCCset.c, in
8504 linkEdit() when calling buildCmdLine(), added linkOptions as
8505 last argument. Now users can pass arguments to gplink via the
8506 -Wl option, main() uses pic16glue() to glue up pic16 programs

8520 gpasm complaining and test the linkage with gplink, _linkCmd and
8521 _asmCmd changed to be more gplink and gpasm friendly
8522 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8523 produced an error when parsed, peep rule 12 is added to utilize
8524 movff, but it is commented out since the pCode does not support
8525 yet a command with 2 address arguments
8527 2003-05-18 <johan AT balder>
8529 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8556 2003-05-11 Borut Razem <borut.razem AT siol.net>
8558 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9544 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9545 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9547 2003-01-07 <johan AT balder>
9549 * src/SDCCast.c (decorateType): fixed bug #600035
9551 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9552 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9562 2003-01-06 <johan AT balder>
9564 * src/SDCCicode.c: fixed array add
9566 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9567 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9568 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9570 2003-01-04 <johan AT balder>
9572 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9574 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9575 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9577 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9578 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9579 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9581 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9582 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9584 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9585 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9587 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9588 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9590 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9592 * in \sdcc\as\mcs51\ changed these files in order to create an
9593 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9594 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9595 following files to include the previous two files: aslink.dsp,
9596 Makefile.aslink, Makefile.bcc, and Makefile.in.
9598 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9599 .adb instead of .cdb
9601 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9603 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9604 value from option --iram-size.
9606 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9608 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9611 2002-09-18 <wiml AT hhhh.org>
9613 * SDCClrange.h: exposed setFromRange() and setToRange()
9614 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9615 packRegsForAccUse() (bug 542397)
9616 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9617 multiple times and emitting the fetch operations more than once
9618 added aopGetUsesAcc() function to allow binary operators to
9619 fetch their operands in the correct order; made genMinus() emit
9620 compact code for X = LITERAL - Y
9622 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9623 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9624 sprintf() in line 1267.
9626 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9627 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9630 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9631 Changes to aslink (All the changes are marked with 'JCF'):
9633 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9636 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9637 area BSEG. Also moves, if possible, the DATA area down into the internal
9638 ram so more space is available.
9640 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9643 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9644 not bytes. Function summary() which creates a memory usage summary
9645 file with extension .mem. Reports of overlaping stack and small stack
9646 size. If the space for the stack is less than 16 bytes aslink trows a
9649 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9650 the 8051. Option 'y' for memory summary output file.
9652 Changes to sdcc (All the changes are marked with 'JCF'):
9654 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9656 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9657 overlaying area for it (uses RegBankUsed[4]).
9659 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9660 bank zero as used by default. By default aslink locates the stack
9661 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9662 the creation of the .mem file. Delegates the allocation of data area
9663 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9664 the begining of the stack area to aslink.
9666 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9667 glue() in SDCCglue.c creates an area for it.
9669 2002-09-03 Borut Razem <borut.razem AT siol.net>
9670 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9671 sdcc/src/pic/glue.c:
9672 introduced atexit() handler for teporay files removal in case of
9673 errors, assertions, ...
9675 2002-08-29 Borut Razem <borut.razem AT siol.net>
9676 * sdcc/support/cpp2/auto-host_vc_in.h:
9677 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9678 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9679 Maybe there is a similar problem with BORLANDC? It should be checked!
9681 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9682 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9683 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9684 was not executed, and the compiler (cl) launched a warning:
9685 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9687 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9688 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9690 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9691 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9693 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9694 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9695 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9696 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9697 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9698 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9699 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9700 - added Release configuration in VS projects
9701 - review of compiler an linker options
9702 - VC .exe files are generated in bin_vc directory, not to interfere
9703 with binaries generated from other projects (cygwin, mingw, bcc ...)
9705 * sdcc/src/yacc.dsp: added
9707 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9708 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9709 and insert the version number definitions from .version
9711 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9713 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9714 added - genarate auto-host.h using auto-host_vc_in.h as template
9717 removed from CVS, generated automatically
9719 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9720 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9722 2002-08-11 Borut Razem <borut.razem AT siol.net>
9723 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9725 2002-08-10 Borut Razem <borut.razem AT siol.net>
9726 * src/SDCCmain.c (main):
9727 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9728 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9729 The consequence was that some temporary files were not removed.
9732 unification of code in functions tempfilename() and tempfile():
9733 function tempnam() is defined in Visual Studio 6.0 and .NET
9735 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9737 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9738 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9739 - removed compiler command line option /WX: Treats all warnings as errors
9740 - update a list of source files, included into the project
9742 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9743 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9744 changed project type to Generic Project so that can be correcly converted to VS.NET project
9746 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9748 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9750 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9752 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9753 added return 0 statements after assert() to make compiler happy
9755 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9756 added newline in the def file to keep MSC compiler satisfied
9758 * sdcc/src/z80/gen.c:
9759 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9760 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9761 - solved MSC error in function aopDump()
9763 * sdcc_vc.h: define PREFIX as "\\sdcc"
9765 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9766 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9769 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9770 - Rewrote the register banking algorithm.
9771 - Added pCode live-range analysis to registers (for now, only non-used and
9772 singly-used registers optimized away)
9774 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9776 * 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.

9801 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9803 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9805 2002-03-28 Johan Knol <johan AT balder>
9807 * src/SDCCval.c: fixed bug #532436
9809 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9811 Added "char *Processor" field to the port structure.
9814 Added -p option. Allows port dependent processor to be specified.
9817 Initialized the new field char *Processor field to NULL in all ports
9820 Compiler generated registers for interrupt context saving
9821 were not getting allocated.
9823 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9826 Fixed left shift. Will promote the left side of a left shift
9827 if a) left shifting more than size of operand or b) when assigned
9828 to something size > size of left side
9830 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9832 tons of changes. Register allocation has been
9833 rewritten. Added customization for the various PICs. Flow
9834 analysis is restructured. ...
9840 Added. device.c is a PIC port hack to accomodate variations
9843 2002-03-13 Michael Hope <michaelh AT vroom>
9845 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9847 2002-03-04 johanknol <johanknol AT manik>
9849 * /src/SDCCval.c: fixed
9851 const unsigned char arr[][2] = { { 0, 1 } };
9852 t18.c:1: error: Initializer element is not constant
9854 2002-03-04 bela <bela AT manik>
9856 * /device/include/mcs51reg.h:
9857 ds89c420 register definition update
9859 2002-03-03 <johan AT FRIJA>

9938 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9940 * sdcc/src/SDCCloop.c:
9941 Previous fix was not good. basic blocks that have "break" or "return" are
9942 not really partof a loop , but live ranges used in these blocks should
9943 be live thru the entire loop, so set partOfLoop but don't add them to
9946 2002-02-21 <johan AT FRIJA>
9948 * src/SDCCcse.c: fixed bug #514308
9950 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9953 Fixed BUG #519583. If a conditional block ended in a return/break
9954 statement inside a loop, it was not being considered part of the loop.
9956 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9958 2002-02-10 Karl Bongers <karl AT turbobit.com>
9961 Fixed up SDCDB debugger somewhat. Updated debugger/README
9962 with lots of comments and notes.
9964 * device/examples/test2.c:
9965 Fix bug, "red" variable not being initialized(compiler complained).
9967 * device/examples/Makefile, examples/test3.c:
9968 Add Makefile in device/examples folder, compiles test3.c
9969 for use as a multiple module SDCDB test case.
9971 * sim/ucsim/cmd.src/cmdset.cc:
9972 Took out debug printfs in ucsim "next" command.
9975 Karl and Johan start ucsim XA support. Most dissassembly working,
9976 about 75% emulation done(plenty of work remaining).
9978 * sim/ucsim/z80.src:
9979 Add Z80 support to ucsim, add test-ucz80 regression test,
9980 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9981 Notice z80 compiler fails on examples/test3.c/crc code.
9983 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9985 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
9986 Added support for --parms-in-bank1
9988 * src/ds390/peeph.def:
9989 added a few more peephole optimzations
9992 1) added __builtin_inp & __builtin_outp used to read in data of given length
9993 from a memory mapped port
9994 2) added __builtin_memcmp
9995 3) added __builtin_swapw swap bytes of a short
9997 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9998 1) handle multiple send & receives from register bank1
9999 2) ralloc can now allocate DPTR1 to some liveRanges
10001 * src/SDCCsymt.c, src/SDCCsymt.h:
10002 changes to handle multiple sends & receives
10004 * src/SDCCptropt.h:
10005 added some pointer arithmetic optimization
10007 * src/SDCCptropt.c:
10008 added some pointer arithmetic optimizations but not stable yet so not
10009 called from anywhere (will get this working shortly)
10011 * src/SDCCopt.c: fixed for multiple sends & receives
10014 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
