126 the left operand is shorter than the result (c* = lit-c* + int),
128 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
131 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
133 * src/.version: increased version number to 2.5.5
134 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
135 linking is done manually in pic16 port's _linkEdit,
136 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
137 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
138 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
139 allocate asmop as AOP_ACC,
140 (aopForRemat): added parameter 'bool result' in function declaration,
141 (pic16_aopGet): return AOP_ACC when accessing WREG,

153 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
154 call to allocReg, not by manually allocating a new one,
155 (pic16_assignRegisters): now before going through the register
156 allocating functions mark all registers as free. This eliminates some
157 side effects resulting from peephole parser done earlier in the backbone

217 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
218 which dumps before the function entry point a data byte which represents
219 the number of the local variables used by the specified function, added
220 'xinst' for initial support for Extended Instruction Support,
221 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
222 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
223 port->fun_prefix anymore (may change later),
224 (genFunction, genEndFunction): do not store/restore local registers for
225 _main (this should take care the --main-return command line option in
227 (genOr): removed some legacy pic-port instructions,
228 * src/pic16/genarith.c (genAddLit): re-enabled old code because
229 performing operations with SFR's causes data to be written more than
230 once to each SFR. Perhaps SFRs should be handled in special cases...
231 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
233 * src/pic16/main.c (_process_pragma): stack bound checking did not take
234 into account for stack starting position,
235 (struct OPTIONS pic16_optionsTable): added command line argument
236 --extended or -y for Extended Instruction Support,
237 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
238 (deassignLRs): *** perhaps the most important change, old 'for' code
239 (commented out for reference), didn't account for some registers which
240 were left marked 'not free' after a pointer operation. The change
241 reduces register usage a lot in some cases

2585 * device/lib/libsdcc.lib: added abs and labs
2586 * device/include/float.h,
2587 * device/lib/_fsmul.c,
2588 * device/lib/printf_fast.c,
2589 * device/lib/printf_tiny.c: updated comments
2591 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2593 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2596 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2598 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2599 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2601 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2603 * device/lib/printf_large.c: removed inline assembly for portability and
2604 readability. Use printf_fast if speed or size are more important.
2605 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2606 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2608 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2610 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2611 prevent compiler warning
2613 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2615 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2616 moved to level 0 and declared as static. Also they are explicit
2617 placed in access bank. This was necessery because some times they
2618 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2619 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2620 optimizations. Currently only compare to unsigned char is implemented,
2621 * src/pic16/gen.c: added fReturnIdx array,
2622 * (struct resolvedIfx) is moved to gen.h and made public,
2623 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2624 * (aopForSym): added an optimization to directly store in stack of
2625 the operand of a SEND iCode,
2626 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2627 but as registers instead (AOP_REG) using the fReturnIdx array,
2628 * (pic16_freeAsmop): remove the freed register from the
2629 _G.sregsAlloc field,
2630 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2631 a compare of 'WREG',
2632 * (pic16_popGetTempRegCond): changed function prototype, now
2633 function takes also a bitVector argument v which holds the current
2634 set of registers that are allocated for stack access by aopForSym,
2635 registers allocated in aopForSym for accessing stack symbols are not
2636 any more part of the functions usedRegs field,
2637 * (genCall): some times aopOp is called for a stack variable to be
2638 send, aopForSym might perform the push, if this is true make sure
2639 that genCall doesn't push the variable twice by testing _G.resDirect,
2640 * (genFunction): changed testing for unspecified interrupt number
2641 from 256 to INTNO_UNSPEC,
2642 * modified selection scheme of frame pointer generation. Previously
2643 if function did use local registers a frame pointer was generated,
2644 now a frame pointer is generated only if function has arguments
2645 (that need PLUSW2 register access), or has stack arguments, or the
2646 compiler is not instructed to omit the frame pointer,
2647 * (genEndFunction): before restoring local registers that were saved
2648 in the function preamble, also restore the registers that *might*
2649 have been allocated for stack access,
2650 * (genRet): removed some old comments,
2651 * (genCmp, the active (RN's) version): added a call to the
2652 pic16_genCmp_special function to perform the compare with a more
2653 robust and optimized way,
2654 * (genInline): a feature has been added in inline code generation,
2655 which allows a wildcard variable substitution when writing inline
2656 assembly. Code is incomplete and experimental therefore undocumented,
2657 * (genCast): changed order of aopOp for result and right to allow
2658 aopForSym to directly load the result if possible,
2659 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2660 perform an optimized compare on some selected special occasions,
2661 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2662 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2663 generate an IVT any more,
2664 * src/pic16/main.c (pic16_optionsTable): added command line option
2666 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2667 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2669 * src/pic16/NOTES: Raphael Neider added in list of active developers
2670 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2671 jumptable_end to prevent bug #,
2672 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2673 inCond and outCond fields,
2674 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2675 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2676 turn off register spilling,
2677 * (packRegsForOneUse): synced with other ports' versions although it
2678 is not used currently,
2679 * (pic16_packRegisters): added an optimization while reading
2680 structure bitfields, some registers may be saved (malloc code is
2681 decreased by 80 bytes)
2683 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2685 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2686 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2687 this can be optimized more?
2689 2005-03-10 Raphael Neider <rneider AT web.de>
2691 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2692 genNearPointerGet): (hopefully) fixed access to bitfields via
2693 pointers (p->bitN = x; and x = p->bitN; failed)
2695 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2738 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2739 to keep the correct label reference count when adding/removing references
2740 to labels. A peephole file using this is appended to patch #1144962.

3328 generated for switch statements. For now you need to set the
3329 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3330 Now 4 algorithms for mcs51 jumptable generation are used:
3331 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3365 * added libc directory. The current version of LibC contains string
3366 functions, ctype functions and macros and some functions of the
3367 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3368 be extensively tested in the future. Standard disclaimer here.

3381 * (pic16_storeForReturn): optimized return of 0,
3382 * (genCmp): experimental code for new genCmp which uses PIC18's
3383 special compare&skip instructions. Initial tests fail some times
3384 with variables grater than 1 byte in size, so new code is disabled,
3385 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3387 * (genCast): began a fix to optimize the casting of a bit to another
3388 bit, now assigning a bitfield to another bitfield will fail, sorry,

3403 * src/pic16/ralloc.c (allocReg): add preliminary support for
3404 supporting a limited set of temporary registers,
3406 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6411 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6413 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6414 loaded with the linker search paths (-L arguments) and the libraries
6415 to be linked with the current source (-l arguments). Changes
6416 currently will affect only the pic16 port.
6417 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6418 include path the port specific paths and port specific libraries,
6419 * gplink command now contains the $3 argument,
6420 * src/pic16/device.h,
6421 * src/pic16/device.c,: structure PIC_device is made public and
6422 renamed to PIC16_device, the same for variable Pics which is renamed

6437 Documenting changes from previous commits.
6438 * configure.in (version 1.56),
6439 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6440 when generating output files to configure the pic16 library,
6441 but now I've commented it out, since gputils aren't installed in the
6442 SF compile farm, so library won't compile
6444 * device/lib/Makefile.in (version 1.56): initially I've added in
6445 target 'all' the prerequestive 'model-pic16' so it compiled the
6446 pic16 library, but now I've commented it out for the same reasons
6448 * added targets 'model-pic16' and 'objects-pic16' to compile the
6450 * added target 'port-specific-objects-pic16' to handle the
6451 generated libraries and copy them into the build/ directory
6452 * added target 'clean-intermediate-pic16' to clean intermediate
6453 files into pic16 directory
6454 * in target 'installdirs' added line to create directory pic16 in
6455 the installation path

6458 added lines to copy all header files to installation path,
6459 * in target 'installdirs' added line create directory for pic16
6460 headers in the installation path

6476 option so that it actually works. Made it specific to the z80, since
6477 the gbz80 doesn't have these kinds of I/O ports.
6479 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6481 * device/include/z180.h,

6508 data are now emitted in sorted order to reduce section naming,
6509 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6510 weren't marked as being in the access bank,
6512 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6514 Added portion of GNU PIC Library under the directory
6515 device/include/pic16 and device/lib/pic16. These files
6516 contain the declarations of SFRs for the PIC18Fxx2 devices.
6517 The directory is initialized via configure from toplevel.

6547 all over. Telling LaTeX to be less strict with word spacing
6548 to better keep the right margin. Changed some notes about
6549 maintainance of the ports in section 3.2.1 - is it OK like this?
6551 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6588 UPPER for immediate operands,
6589 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6591 * src/pic16/peeph.def: all peepholes with movff are commented out,
6592 because there is a problem in the pcode peep optimizer,
6593 * src/pic16/ralloc.c: the register allocator can now reuse local
6594 function symbols for another function. This saves register usage.

6703 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6705 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6706 (default behaviour).
6708 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6710 A python script to validate compiler diagnostic messages. It can be
6711 used to verify that sdcc complains about bad c source code and
6712 gives a good location of the error.
6713 * support/valdiag/Makefile,
6714 * support/valdiag/valdiag.py,

6734 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6736 * sdcc.spec: updated

6745 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6747 PIC16 port related changes:
6748 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6749 added variable stackPos,
6751 * gen.c: genCall, assignResultValue: added support for
6752 pushing/retrieving function parameters to/from stack,
6753 genFunction,genEndFunction: setup stack frame for the
6755 genAddrOf: will be changed according to bug 863624
6757 * added files genutils.c and genutils.h which contain gen*
6758 debugged and optimised functions extracted from gen.c
6760 * glue.c: added variable 'externs' which holds extern symbols,
6761 pic16emitRegularMap: is modified to properly handle relocatable
6762 symbols under the new scheme,
6763 pic16createInterruptVect: is modified
6764 pic16printPublics: is modified to emit 'global' assembler directives,
6765 added pic16_printExterns to print extern symbols,
6766 pic16glue: initializes stack/frame pointer in the beginning of
6767 the assembly output. Temporary hack, will be corrected later,
6768 because gplink yet does not support stack and SDCC does not
6769 yet support a type of crt0.o object to create the final binary.
6771 * Removed many lines that contain 8051 legacy code.
6772 * The code is finally placed under a 'code' directive.
6773 * Added port specific options.
6775 * _process_pragma: simplified since now we do not need *special*
6776 include file to define SFR registers. But a separate header
6777 will be needed. This will be developed later.
6778 * _pic16_parseOptions: added, parses port specific options:
6779 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6780 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6781 --preplace-udata-with=
6783 * _pic16_setDefaultOptions: modified to initialize section names,
6784 but hack is temporarly out of order since it needs improvement.
6785 * _pic16_genAssemblerPreamble: configuration words are emitted by
6786 their address instead of their name. This part is incomplete and
6787 supports only the 18Fxx2 devices. Other devices will emit an error
6788 during assembly since they do not contain the same set of config
6790 * _pic16_genIVT: is modified,
6792 * pcode.c: added definitions for some hardware registers that are needed
6794 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6795 All PCI entries are updated. Now LFSR is supported.
6796 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6797 * added pic16_newpCodeOpLit2 to support instructions with
6798 two literal arguments
6799 * pic16_pCode2str: corrected code that emits assembler instructions
6800 with two literal operands and those that have an access bit modifier
6801 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6802 this fixes a bug which caused some labels to be lost, when an
6803 assembler directive was added, i.e. banksel,
6804 * pic16_FixRegisterBanking: improved logic that causes the insertion
6806 * InlineFunction: functions that are called once, are not any more
6807 inlined. This can be a port option in the future,
6809 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6811 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6812 hold the corresponding uninitialized symbols,
6813 * pic16_allocProcessorRegister: registers have explicit marked the
6815 * pic16_allocInternalRegister: registers are explicit marked as
6817 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6818 processing list, so bit registers were lost,
6821 * ralloc.h: added field 'accessBank' and original symbol operand
6822 in register definition,
6823 * removed the field isMapped from register definition,
6825 ** Several functions have been removed from various sources:
6826 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6827 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6828 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6829 pic16_assignRelocatableRegisters
6831 ** others have been introduced:
6832 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6833 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6835 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6837 * support/scripts/inc2h.pl: changed definition of BIT_AT
6838 to emit 'sbit at' instead of 'bit at'. This was a request.
6840 PIC16 port related preliminary changes:
6841 * gen.c: prefixed function popRegFromString with
6842 pic16_ and all references to it corrected
6843 * pcode.c: all pic16_pc_* hardware registers prefixed
6844 with underscore (_),
6845 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6846 * ralloc.c: newReg(): when register is REG_SFR then
6847 set address to rIdx,
6848 pic16_allocProcessorRegister(): marks register wasUsed=0
6849 pic16_writeUsedRegs(): added a call to assign processor
6850 registers via pic16_assignFixedRegisters
6852 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6854 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6855 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6856 variables in unused register banks. Also the SSEG is placed
6857 wherever there is enough space for it, and IDATA can be anywhere
6858 in internal RAM. For now compile using -Wl-Y[stack_size].
6859 The mem file is different for this option as well, since it
6860 makes no sense of talking about DSEG lenght.
6862 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6864 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6865 in certain cases, e.g. when ROM assignment, patch provided
6866 from Albert den Haan.
6868 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7011 * src/mcs51/peephole.def,
7012 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7013 (allows non-interrupt and interrupt code to safely compete for a resource

7753 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7754 support for standard C idiom of memory mapped variables; for
7755 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7756 to xdata int at 0x1234 tempvar = 1.
7757 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7758 provided by Akiya ISHIDA

7774 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7776 Fixed bug #621531 (const & volatile confusion in the type chain).
7777 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7843 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7844 pcoderegs.h, ralloc.c, ralloc.h
7845 * main.c: added top header and GPL license notice

7869 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7870 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7871 fetching of the pointer
7872 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7873 copied from genNearPointerSet()
7874 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7875 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7876 If they pop r0/r1 they must be called in the opposite order than aopOp().
7877 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7878 (resp. --stack-auto), prepared for --xstack

7887 these ports have their own __sdcc_external_start()
7889 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7891 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7892 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7893 type for bits was changed. It resulted in bit variables becoming
7894 global, which is not permitted in PIC 14 assembly output.
7896 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7898 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7909 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7911 A few small changes that speed up the peephole optimizer.
7915 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7917 Try to make the peephole optimizer smarter by maintaining
7918 an association between the assembly source code and the
7919 iCodes that originated them. Put this information to use
7920 with a new peephole rule condition "notVolatile" so that
7921 the rules can be aggressive yet still safe.
7926 * src/mcs51/peeph.def
7928 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7932 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7933 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7934 if the left or right operand symbols have the accuse flag set.
7936 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7938 Changed the type of the result of the ! (NOT) operator to char;
7939 previously it returned the same type as the source. This allows
7940 us to eliminate all the genFloatNot functions (all of its target
7941 implementations were very buggy) since !float can use the same
7944 * src/SDCCicode.c (ast2iCode): ! returns char
7945 * src/mcs51/gen.c (genNot, genNotFloat),
7946 * src/ds390/gen.c (genNot, genNotFloat),
7947 * src/z80/gen.c (genNot, genNotFloat),
7948 * src/pic/gen.c (genNot, genNotFloat),
7949 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7951 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7953 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7954 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7955 during interrupts. Ensure WSAVE is located at a shared bank address.
7956 2. Fixed page selection in some places
7957 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7958 the registers name strings.
7959 4. Fixed "signed / unsigned compare" compiler warnings.
7960 5. The PIC port manages its own allocation of the general purpose
7961 registers, but makes no attempt to reuse them. As a result when
7962 compiling it soon runs out of general purpose registers. Some
7963 additional code was added to the files pcode.c and device.c to walk
7964 through the function call tree and rename the registers so that they
7974 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7975 genPlus() & genMinus() when the result is the same as left or right
7977 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7981 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7983 Made bitfield a distinct type from bit so that bitfields
7984 convert as per ANSI C and bits retain their traditional
7985 boolean style behaviour. Implemented bitfield support in
7993 * src/ds390/gen.c: bit v bitfield split
7994 * src/z80/gen.c: New support for bitfields
7995 * support/regression/tests/bitfields.c: reenabled z80,
7998 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8000 Rules 246.x, 247.x relate to bitfields, the others speed up
8001 access to xdata mapped I/O devices.
8003 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8005 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8007 Cleaned up genPackBits and genUnpackBits and added two helper
8008 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8009 for literal assignments in genPackBits (thanks to Frieder for
8015 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8017 Fixed bug #748310 (pointer to function type mishandled when the
8018 function name is omitted). Also fixed a SIGSEGV when a function
8019 attribute (reentrant, etc) is used on a non-function or on a
8020 function but misplaced before the parameter list.
8022 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8024 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8025 * support/Util/SDCCerr.h,
8026 * support/Util/SDCCerr.c: Added func attr misuse error msg
8028 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8030 Fixed bug #787649 by anonymous
8031 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
8032 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
8034 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8036 Fixed numerous bitfield problems.
8038 * src/SDCC.y: More bitfield related error checking
8040 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
8041 * support/Util/SDCCerr.h,

8047 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8049 Made the constant following the "interrupt" keyword optional. If
8050 omitted, the function will not automatically be given an entry
8051 in the interrupt vector table (similar to #pragma NOIV, but
8052 less syntacticly kludgy). The interrupt number is also now
8053 range checked. Also fixed a bug in the high order bit example
8060 * support/Util/SDCCerr.c
8061 * support/Util/SDCCerr.h
8064 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8066 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8067 * src/SDCCicode.c (operandOperation): rewritten some ops
8068 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8069 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8071 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8072 be re-activated by defining REDUCE_LITERALS)
8073 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8074 unsigned, but are signed by default
8075 * src/SDCCval.c (constVal): rearranged
8076 * src/SDCCval.c (valMod): preliminary fix
8077 * src/SDCCval.c (valCastLiteral): use TYPE_* types
8078 * support/regression/literalop.c: added, work in progress

8582 * src/SDCCmain.c: linkOptions is changed to set *,
8583 added if/endif conditional macros to remove options help
8584 messages from optionsTable when a port is not configured, added
8585 support for the PIc16 port in the ports table, when executing
8586 the compiler with no port specified on command line, a default
8587 port is selected with the new macro DEFAULT_PORT which is
8588 defined in port.h, in setDefaultOptions() linkOptions is removed
8589 from initialization assignment, since now it is a set,
8590 parseCmdLine uses setParseWithComma for linkOptions, in
8591 linkEdit() linkOptions are accessed with new function indexSet()
8592 which returns the i'th item of a set variable. See SDCCset.c, in
8593 linkEdit() when calling buildCmdLine(), added linkOptions as
8594 last argument. Now users can pass arguments to gplink via the
8595 -Wl option, main() uses pic16glue() to glue up pic16 programs

8607 * src/pic16/glue.c: commented out some error producing lines
8608 * src/pic16/main.c: __config directives are commented out to stop
8609 gpasm complaining and test the linkage with gplink, _linkCmd and
8610 _asmCmd changed to be more gplink and gpasm friendly
8611 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8612 produced an error when parsed, peep rule 12 is added to utilize
8613 movff, but it is commented out since the pCode does not support
8614 yet a command with 2 address arguments
8616 2003-05-18 <johan AT balder>
8618 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9653 * src/SDCCicode.c: fixed array add
9655 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9656 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9657 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9659 2003-01-04 <johan AT balder>
9661 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9663 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9676 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9677 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9679 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9681 * in \sdcc\as\mcs51\ changed these files in order to create an
9682 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9683 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9684 following files to include the previous two files: aslink.dsp,
9685 Makefile.aslink, Makefile.bcc, and Makefile.in.
9687 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9688 .adb instead of .cdb
9690 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9692 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9693 value from option --iram-size.
9695 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9697 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9700 2002-09-18 <wiml AT hhhh.org>
9702 * SDCClrange.h: exposed setFromRange() and setToRange()
9703 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9704 packRegsForAccUse() (bug 542397)
9705 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9706 multiple times and emitting the fetch operations more than once
9707 added aopGetUsesAcc() function to allow binary operators to
9708 fetch their operands in the correct order; made genMinus() emit
9709 compact code for X = LITERAL - Y
9711 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9712 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9713 sprintf() in line 1267.
9715 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9716 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9719 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9720 Changes to aslink (All the changes are marked with 'JCF'):
9722 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9725 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9726 area BSEG. Also moves, if possible, the DATA area down into the internal
9727 ram so more space is available.
9729 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9732 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9733 not bytes. Function summary() which creates a memory usage summary
9734 file with extension .mem. Reports of overlaping stack and small stack
9735 size. If the space for the stack is less than 16 bytes aslink trows a
9738 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9739 the 8051. Option 'y' for memory summary output file.
9741 Changes to sdcc (All the changes are marked with 'JCF'):
9743 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9745 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9746 overlaying area for it (uses RegBankUsed[4]).
9748 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9749 bank zero as used by default. By default aslink locates the stack
9750 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9751 the creation of the .mem file. Delegates the allocation of data area
9752 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9753 the begining of the stack area to aslink.
9755 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9756 glue() in SDCCglue.c creates an area for it.
9758 2002-09-03 Borut Razem <borut.razem AT siol.net>
9759 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9760 sdcc/src/pic/glue.c:
9761 introduced atexit() handler for teporay files removal in case of
9762 errors, assertions, ...
9764 2002-08-29 Borut Razem <borut.razem AT siol.net>
9765 * sdcc/support/cpp2/auto-host_vc_in.h:
9766 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9767 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9768 Maybe there is a similar problem with BORLANDC? It should be checked!
9770 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9771 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9772 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9773 was not executed, and the compiler (cl) launched a warning:
9774 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9776 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9777 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9779 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9780 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9782 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9783 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9784 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9785 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9786 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9787 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9788 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9789 - added Release configuration in VS projects
9790 - review of compiler an linker options
9791 - VC .exe files are generated in bin_vc directory, not to interfere
9792 with binaries generated from other projects (cygwin, mingw, bcc ...)
9794 * sdcc/src/yacc.dsp: added
9796 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9797 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9798 and insert the version number definitions from .version
9800 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9802 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9803 added - genarate auto-host.h using auto-host_vc_in.h as template
9806 removed from CVS, generated automatically
9808 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9809 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9811 2002-08-11 Borut Razem <borut.razem AT siol.net>
9812 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9814 2002-08-10 Borut Razem <borut.razem AT siol.net>
9815 * src/SDCCmain.c (main):
9816 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9817 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9818 The consequence was that some temporary files were not removed.
9821 unification of code in functions tempfilename() and tempfile():
9822 function tempnam() is defined in Visual Studio 6.0 and .NET
9824 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9826 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9827 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9828 - removed compiler command line option /WX: Treats all warnings as errors
9829 - update a list of source files, included into the project
9831 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9832 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9833 changed project type to Generic Project so that can be correcly converted to VS.NET project
9835 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9837 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9839 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9841 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9842 added return 0 statements after assert() to make compiler happy
9844 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9845 added newline in the def file to keep MSC compiler satisfied
9847 * sdcc/src/z80/gen.c:
9848 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9849 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9850 - solved MSC error in function aopDump()
9852 * sdcc_vc.h: define PREFIX as "\\sdcc"
9854 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9855 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9857 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9858 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9859 - Rewrote the register banking algorithm.
9860 - Added pCode live-range analysis to registers (for now, only non-used and
9861 singly-used registers optimized away)
9863 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9865 * 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.

9894 2002-03-28 Johan Knol <johan AT balder>
9896 * src/SDCCval.c: fixed bug #532436
9898 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9900 Added "char *Processor" field to the port structure.
9903 Added -p option. Allows port dependent processor to be specified.
9906 Initialized the new field char *Processor field to NULL in all ports
9909 Compiler generated registers for interrupt context saving
9910 were not getting allocated.
9912 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9915 Fixed left shift. Will promote the left side of a left shift
9916 if a) left shifting more than size of operand or b) when assigned
9917 to something size > size of left side
9919 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9921 tons of changes. Register allocation has been
9922 rewritten. Added customization for the various PICs. Flow
9923 analysis is restructured. ...
9929 Added. device.c is a PIC port hack to accomodate variations
9932 2002-03-13 Michael Hope <michaelh AT vroom>
9934 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9936 2002-03-04 johanknol <johanknol AT manik>
