130 2006-03-16 Raphael Neider <rneider AT web.de>
132 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
133 the left operand is shorter than the result (c* = lit-c* + int),
135 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
138 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
140 * src/.version: increased version number to 2.5.5
141 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
142 linking is done manually in pic16 port's _linkEdit,
143 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
144 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
145 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
146 allocate asmop as AOP_ACC,
147 (aopForRemat): added parameter 'bool result' in function declaration,
148 (pic16_aopGet): return AOP_ACC when accessing WREG,

160 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
161 call to allocReg, not by manually allocating a new one,
162 (pic16_assignRegisters): now before going through the register
163 allocating functions mark all registers as free. This eliminates some
164 side effects resulting from peephole parser done earlier in the backbone
166 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

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

2586 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2588 * device/include/stdint.h: added
2589 * device/lib/abs.c: added
2590 * device/lib/labs.c: added
2591 * device/include/stdlib.h: added abs() and labs() prototypes
2592 * device/lib/libsdcc.lib: added abs and labs
2593 * device/include/float.h,
2594 * device/lib/_fsmul.c,
2595 * device/lib/printf_fast.c,
2596 * device/lib/printf_tiny.c: updated comments
2598 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2600 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2603 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2605 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2606 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2608 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2610 * device/lib/printf_large.c: removed inline assembly for portability and
2611 readability. Use printf_fast if speed or size are more important.
2612 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2613 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2615 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2617 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2618 prevent compiler warning
2620 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2622 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2623 moved to level 0 and declared as static. Also they are explicit
2624 placed in access bank. This was necessery because some times they
2625 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2626 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2627 optimizations. Currently only compare to unsigned char is implemented,
2628 * src/pic16/gen.c: added fReturnIdx array,
2629 * (struct resolvedIfx) is moved to gen.h and made public,
2630 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2631 * (aopForSym): added an optimization to directly store in stack of
2632 the operand of a SEND iCode,
2633 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2634 but as registers instead (AOP_REG) using the fReturnIdx array,
2635 * (pic16_freeAsmop): remove the freed register from the
2636 _G.sregsAlloc field,
2637 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2638 a compare of 'WREG',
2639 * (pic16_popGetTempRegCond): changed function prototype, now
2640 function takes also a bitVector argument v which holds the current
2641 set of registers that are allocated for stack access by aopForSym,
2642 registers allocated in aopForSym for accessing stack symbols are not
2643 any more part of the functions usedRegs field,
2644 * (genCall): some times aopOp is called for a stack variable to be
2645 send, aopForSym might perform the push, if this is true make sure
2646 that genCall doesn't push the variable twice by testing _G.resDirect,
2647 * (genFunction): changed testing for unspecified interrupt number
2648 from 256 to INTNO_UNSPEC,
2649 * modified selection scheme of frame pointer generation. Previously
2650 if function did use local registers a frame pointer was generated,
2651 now a frame pointer is generated only if function has arguments
2652 (that need PLUSW2 register access), or has stack arguments, or the
2653 compiler is not instructed to omit the frame pointer,
2654 * (genEndFunction): before restoring local registers that were saved
2655 in the function preamble, also restore the registers that *might*
2656 have been allocated for stack access,
2657 * (genRet): removed some old comments,
2658 * (genCmp, the active (RN's) version): added a call to the
2659 pic16_genCmp_special function to perform the compare with a more
2660 robust and optimized way,
2661 * (genInline): a feature has been added in inline code generation,
2662 which allows a wildcard variable substitution when writing inline
2663 assembly. Code is incomplete and experimental therefore undocumented,
2664 * (genCast): changed order of aopOp for result and right to allow
2665 aopForSym to directly load the result if possible,
2666 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2667 perform an optimized compare on some selected special occasions,
2668 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2669 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2670 generate an IVT any more,
2671 * src/pic16/main.c (pic16_optionsTable): added command line option
2673 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2674 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2676 * src/pic16/NOTES: Raphael Neider added in list of active developers
2677 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2678 jumptable_end to prevent bug #,
2679 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2680 inCond and outCond fields,
2681 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2682 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2683 turn off register spilling,
2684 * (packRegsForOneUse): synced with other ports' versions although it
2685 is not used currently,
2686 * (pic16_packRegisters): added an optimization while reading
2687 structure bitfields, some registers may be saved (malloc code is
2688 decreased by 80 bytes)
2690 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2692 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2693 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2694 this can be optimized more?
2696 2005-03-10 Raphael Neider <rneider AT web.de>
2698 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2699 genNearPointerGet): (hopefully) fixed access to bitfields via
2700 pointers (p->bitN = x; and x = p->bitN; failed)
2702 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2745 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2746 to keep the correct label reference count when adding/removing references
2747 to labels. A peephole file using this is appended to patch #1144962.

3025 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
3026 access stack and frame pointers. They are initially assigned to
3027 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3028 accessing SFRs. Updated all occurences of modification of stack or
3029 frame pointer in gen.c and pcode.c,

3335 generated for switch statements. For now you need to set the
3336 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3337 Now 4 algorithms for mcs51 jumptable generation are used:
3338 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3370 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3372 * added libc directory. The current version of LibC contains string
3373 functions, ctype functions and macros and some functions of the
3374 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3375 be extensively tested in the future. Standard disclaimer here.
3376 Library is not automatically build yet. But one can build it by
3377 invoking 'make' inside the libc directory.

3388 * (pic16_storeForReturn): optimized return of 0,
3389 * (genCmp): experimental code for new genCmp which uses PIC18's
3390 special compare&skip instructions. Initial tests fail some times
3391 with variables grater than 1 byte in size, so new code is disabled,
3392 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3394 * (genCast): began a fix to optimize the casting of a bit to another
3395 bit, now assigning a bitfield to another bitfield will fail, sorry,

3409 registers when it shouldn't,
3410 * src/pic16/ralloc.c (allocReg): add preliminary support for
3411 supporting a limited set of temporary registers,
3413 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3437 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3439 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6418 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6420 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6421 loaded with the linker search paths (-L arguments) and the libraries
6422 to be linked with the current source (-l arguments). Changes
6423 currently will affect only the pic16 port.
6424 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6425 include path the port specific paths and port specific libraries,
6426 * gplink command now contains the $3 argument,
6427 * src/pic16/device.h,
6428 * src/pic16/device.c,: structure PIC_device is made public and
6429 renamed to PIC16_device, the same for variable Pics which is renamed

6444 Documenting changes from previous commits.
6445 * configure.in (version 1.56),
6446 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6447 when generating output files to configure the pic16 library,
6448 but now I've commented it out, since gputils aren't installed in the
6449 SF compile farm, so library won't compile
6451 * device/lib/Makefile.in (version 1.56): initially I've added in
6452 target 'all' the prerequestive 'model-pic16' so it compiled the
6453 pic16 library, but now I've commented it out for the same reasons
6455 * added targets 'model-pic16' and 'objects-pic16' to compile the
6457 * added target 'port-specific-objects-pic16' to handle the
6458 generated libraries and copy them into the build/ directory
6459 * added target 'clean-intermediate-pic16' to clean intermediate
6460 files into pic16 directory
6461 * in target 'installdirs' added line to create directory pic16 in
6462 the installation path

6465 added lines to copy all header files to installation path,
6466 * in target 'installdirs' added line create directory for pic16
6467 headers in the installation path

6482 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6483 option so that it actually works. Made it specific to the z80, since
6484 the gbz80 doesn't have these kinds of I/O ports.
6486 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6488 * device/include/z180.h,

6512 via literal number. The symbol is placed in the corresponding
6513 position of the data ram
6514 * (pic16_dump_section): relocatable and absolute uninitialized
6515 data are now emitted in sorted order to reduce section naming,
6516 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6517 weren't marked as being in the access bank,
6519 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6521 Added portion of GNU PIC Library under the directory
6522 device/include/pic16 and device/lib/pic16. These files
6523 contain the declarations of SFRs for the PIC18Fxx2 devices.
6524 The directory is initialized via configure from toplevel.
6526 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6554 all over. Telling LaTeX to be less strict with word spacing
6555 to better keep the right margin. Changed some notes about
6556 maintainance of the ports in section 3.2.1 - is it OK like this?
6558 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6712 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6713 (default behaviour).
6715 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6717 A python script to validate compiler diagnostic messages. It can be
6718 used to verify that sdcc complains about bad c source code and

6741 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6743 * sdcc.spec: updated
6744 * device/include/Makefile.in: don't install CVS directories

6752 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6754 PIC16 port related changes:
6755 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6756 added variable stackPos,
6758 * gen.c: genCall, assignResultValue: added support for
6759 pushing/retrieving function parameters to/from stack,
6760 genFunction,genEndFunction: setup stack frame for the
6762 genAddrOf: will be changed according to bug 863624
6764 * added files genutils.c and genutils.h which contain gen*
6765 debugged and optimised functions extracted from gen.c
6767 * glue.c: added variable 'externs' which holds extern symbols,
6768 pic16emitRegularMap: is modified to properly handle relocatable
6769 symbols under the new scheme,
6770 pic16createInterruptVect: is modified
6771 pic16printPublics: is modified to emit 'global' assembler directives,
6772 added pic16_printExterns to print extern symbols,
6773 pic16glue: initializes stack/frame pointer in the beginning of
6774 the assembly output. Temporary hack, will be corrected later,
6775 because gplink yet does not support stack and SDCC does not
6776 yet support a type of crt0.o object to create the final binary.
6778 * Removed many lines that contain 8051 legacy code.
6779 * The code is finally placed under a 'code' directive.
6780 * Added port specific options.
6782 * _process_pragma: simplified since now we do not need *special*
6783 include file to define SFR registers. But a separate header
6784 will be needed. This will be developed later.
6785 * _pic16_parseOptions: added, parses port specific options:
6786 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6787 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6788 --preplace-udata-with=
6790 * _pic16_setDefaultOptions: modified to initialize section names,
6791 but hack is temporarly out of order since it needs improvement.
6792 * _pic16_genAssemblerPreamble: configuration words are emitted by
6793 their address instead of their name. This part is incomplete and
6794 supports only the 18Fxx2 devices. Other devices will emit an error
6795 during assembly since they do not contain the same set of config
6797 * _pic16_genIVT: is modified,
6799 * pcode.c: added definitions for some hardware registers that are needed
6801 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6802 All PCI entries are updated. Now LFSR is supported.
6803 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6804 * added pic16_newpCodeOpLit2 to support instructions with
6805 two literal arguments
6806 * pic16_pCode2str: corrected code that emits assembler instructions
6807 with two literal operands and those that have an access bit modifier
6808 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6809 this fixes a bug which caused some labels to be lost, when an
6810 assembler directive was added, i.e. banksel,
6811 * pic16_FixRegisterBanking: improved logic that causes the insertion
6813 * InlineFunction: functions that are called once, are not any more
6814 inlined. This can be a port option in the future,
6816 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6818 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6819 hold the corresponding uninitialized symbols,
6820 * pic16_allocProcessorRegister: registers have explicit marked the
6822 * pic16_allocInternalRegister: registers are explicit marked as
6824 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6825 processing list, so bit registers were lost,
6828 * ralloc.h: added field 'accessBank' and original symbol operand
6829 in register definition,
6830 * removed the field isMapped from register definition,
6832 ** Several functions have been removed from various sources:
6833 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6834 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6835 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6836 pic16_assignRelocatableRegisters
6838 ** others have been introduced:
6839 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6840 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6842 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6844 * support/scripts/inc2h.pl: changed definition of BIT_AT
6845 to emit 'sbit at' instead of 'bit at'. This was a request.
6847 PIC16 port related preliminary changes:
6848 * gen.c: prefixed function popRegFromString with
6849 pic16_ and all references to it corrected
6850 * pcode.c: all pic16_pc_* hardware registers prefixed
6851 with underscore (_),
6852 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6853 * ralloc.c: newReg(): when register is REG_SFR then
6854 set address to rIdx,
6855 pic16_allocProcessorRegister(): marks register wasUsed=0
6856 pic16_writeUsedRegs(): added a call to assign processor
6857 registers via pic16_assignFixedRegisters
6859 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6861 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6862 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6863 variables in unused register banks. Also the SSEG is placed
6864 wherever there is enough space for it, and IDATA can be anywhere
6865 in internal RAM. For now compile using -Wl-Y[stack_size].
6866 The mem file is different for this option as well, since it
6867 makes no sense of talking about DSEG lenght.
6869 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6871 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6872 in certain cases, e.g. when ROM assignment, patch provided
6873 from Albert den Haan.
6875 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7018 * src/mcs51/peephole.def,
7019 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7020 (allows non-interrupt and interrupt code to safely compete for a resource

7760 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7761 support for standard C idiom of memory mapped variables; for
7762 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7763 to xdata int at 0x1234 tempvar = 1.
7764 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7765 provided by Akiya ISHIDA

7781 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7783 Fixed bug #621531 (const & volatile confusion in the type chain).
7784 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7850 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7851 pcoderegs.h, ralloc.c, ralloc.h
7852 * main.c: added top header and GPL license notice

7876 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7877 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7878 fetching of the pointer
7879 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7880 copied from genNearPointerSet()
7881 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7882 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7883 If they pop r0/r1 they must be called in the opposite order than aopOp().
7884 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7885 (resp. --stack-auto), prepared for --xstack

7894 these ports have their own __sdcc_external_start()
7896 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7898 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7899 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7900 type for bits was changed. It resulted in bit variables becoming
7901 global, which is not permitted in PIC 14 assembly output.
7903 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7905 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7916 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7918 A few small changes that speed up the peephole optimizer.
7922 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7924 Try to make the peephole optimizer smarter by maintaining
7925 an association between the assembly source code and the
7926 iCodes that originated them. Put this information to use
7927 with a new peephole rule condition "notVolatile" so that
7928 the rules can be aggressive yet still safe.
7933 * src/mcs51/peeph.def
7935 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7939 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7940 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7941 if the left or right operand symbols have the accuse flag set.
7943 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7945 Changed the type of the result of the ! (NOT) operator to char;
7946 previously it returned the same type as the source. This allows
7947 us to eliminate all the genFloatNot functions (all of its target
7948 implementations were very buggy) since !float can use the same
7951 * src/SDCCicode.c (ast2iCode): ! returns char
7952 * src/mcs51/gen.c (genNot, genNotFloat),
7953 * src/ds390/gen.c (genNot, genNotFloat),
7954 * src/z80/gen.c (genNot, genNotFloat),
7955 * src/pic/gen.c (genNot, genNotFloat),

7958 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7960 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7961 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7962 during interrupts. Ensure WSAVE is located at a shared bank address.
7963 2. Fixed page selection in some places
7964 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7965 the registers name strings.
7966 4. Fixed "signed / unsigned compare" compiler warnings.
7967 5. The PIC port manages its own allocation of the general purpose
7968 registers, but makes no attempt to reuse them. As a result when
7969 compiling it soon runs out of general purpose registers. Some
7970 additional code was added to the files pcode.c and device.c to walk
7971 through the function call tree and rename the registers so that they
7981 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7982 genPlus() & genMinus() when the result is the same as left or right
7984 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7988 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7990 Made bitfield a distinct type from bit so that bitfields
7991 convert as per ANSI C and bits retain their traditional
7992 boolean style behaviour. Implemented bitfield support in
8000 * src/ds390/gen.c: bit v bitfield split
8001 * src/z80/gen.c: New support for bitfields
8002 * support/regression/tests/bitfields.c: reenabled z80,
8005 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8007 Rules 246.x, 247.x relate to bitfields, the others speed up
8008 access to xdata mapped I/O devices.
8010 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8012 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8014 Cleaned up genPackBits and genUnpackBits and added two helper
8015 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8016 for literal assignments in genPackBits (thanks to Frieder for
8022 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8024 Fixed bug #748310 (pointer to function type mishandled when the
8025 function name is omitted). Also fixed a SIGSEGV when a function
8026 attribute (reentrant, etc) is used on a non-function or on a
8027 function but misplaced before the parameter list.
8029 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8031 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8032 * support/Util/SDCCerr.h,
8033 * support/Util/SDCCerr.c: Added func attr misuse error msg
8035 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8037 Fixed bug #787649 by anonymous
8038 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
8039 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
8041 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8043 Fixed numerous bitfield problems.

8054 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8056 Made the constant following the "interrupt" keyword optional. If
8057 omitted, the function will not automatically be given an entry
8058 in the interrupt vector table (similar to #pragma NOIV, but
8059 less syntacticly kludgy). The interrupt number is also now
8060 range checked. Also fixed a bug in the high order bit example
8067 * support/Util/SDCCerr.c
8068 * support/Util/SDCCerr.h
8071 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8073 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8074 * src/SDCCicode.c (operandOperation): rewritten some ops
8075 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8076 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8078 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8079 be re-activated by defining REDUCE_LITERALS)

8589 * src/SDCCmain.c: linkOptions is changed to set *,
8590 added if/endif conditional macros to remove options help
8591 messages from optionsTable when a port is not configured, added
8592 support for the PIc16 port in the ports table, when executing
8593 the compiler with no port specified on command line, a default
8594 port is selected with the new macro DEFAULT_PORT which is
8595 defined in port.h, in setDefaultOptions() linkOptions is removed
8596 from initialization assignment, since now it is a set,
8597 parseCmdLine uses setParseWithComma for linkOptions, in
8598 linkEdit() linkOptions are accessed with new function indexSet()
8599 which returns the i'th item of a set variable. See SDCCset.c, in
8600 linkEdit() when calling buildCmdLine(), added linkOptions as
8601 last argument. Now users can pass arguments to gplink via the
8602 -Wl option, main() uses pic16glue() to glue up pic16 programs

8615 * src/pic16/main.c: __config directives are commented out to stop
8616 gpasm complaining and test the linkage with gplink, _linkCmd and
8617 _asmCmd changed to be more gplink and gpasm friendly
8618 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8619 produced an error when parsed, peep rule 12 is added to utilize
8620 movff, but it is commented out since the pCode does not support
8621 yet a command with 2 address arguments
8623 2003-05-18 <johan AT balder>
8625 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9660 * src/SDCCicode.c: fixed array add
9662 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9663 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9664 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9666 2003-01-04 <johan AT balder>
9668 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9670 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9671 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9673 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9674 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9680 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9681 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9683 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9684 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9686 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9688 * in \sdcc\as\mcs51\ changed these files in order to create an
9689 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9690 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9691 following files to include the previous two files: aslink.dsp,
9692 Makefile.aslink, Makefile.bcc, and Makefile.in.
9694 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9695 .adb instead of .cdb
9697 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9699 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9700 value from option --iram-size.
9702 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9704 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9707 2002-09-18 <wiml AT hhhh.org>
9709 * SDCClrange.h: exposed setFromRange() and setToRange()
9710 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9711 packRegsForAccUse() (bug 542397)
9712 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9713 multiple times and emitting the fetch operations more than once
9714 added aopGetUsesAcc() function to allow binary operators to
9715 fetch their operands in the correct order; made genMinus() emit
9716 compact code for X = LITERAL - Y
9718 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9719 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9720 sprintf() in line 1267.
9722 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9723 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9726 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9727 Changes to aslink (All the changes are marked with 'JCF'):
9729 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9732 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9733 area BSEG. Also moves, if possible, the DATA area down into the internal
9734 ram so more space is available.
9736 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9739 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9740 not bytes. Function summary() which creates a memory usage summary
9741 file with extension .mem. Reports of overlaping stack and small stack
9742 size. If the space for the stack is less than 16 bytes aslink trows a
9745 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9746 the 8051. Option 'y' for memory summary output file.
9748 Changes to sdcc (All the changes are marked with 'JCF'):
9750 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9752 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9753 overlaying area for it (uses RegBankUsed[4]).
9755 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9756 bank zero as used by default. By default aslink locates the stack
9757 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9758 the creation of the .mem file. Delegates the allocation of data area
9759 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9760 the begining of the stack area to aslink.
9762 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9763 glue() in SDCCglue.c creates an area for it.
9765 2002-09-03 Borut Razem <borut.razem AT siol.net>
9766 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9767 sdcc/src/pic/glue.c:
9768 introduced atexit() handler for teporay files removal in case of
9769 errors, assertions, ...
9771 2002-08-29 Borut Razem <borut.razem AT siol.net>
9772 * sdcc/support/cpp2/auto-host_vc_in.h:
9773 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9774 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9775 Maybe there is a similar problem with BORLANDC? It should be checked!
9777 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9778 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9779 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9780 was not executed, and the compiler (cl) launched a warning:
9781 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9783 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9784 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9786 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9787 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9789 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9790 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9791 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9792 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9793 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9794 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9795 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9796 - added Release configuration in VS projects
9797 - review of compiler an linker options
9798 - VC .exe files are generated in bin_vc directory, not to interfere
9799 with binaries generated from other projects (cygwin, mingw, bcc ...)
9801 * sdcc/src/yacc.dsp: added
9803 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9804 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9805 and insert the version number definitions from .version
9807 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9809 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9810 added - genarate auto-host.h using auto-host_vc_in.h as template
9813 removed from CVS, generated automatically
9815 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9816 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9818 2002-08-11 Borut Razem <borut.razem AT siol.net>
9819 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9821 2002-08-10 Borut Razem <borut.razem AT siol.net>
9822 * src/SDCCmain.c (main):
9823 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9824 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9825 The consequence was that some temporary files were not removed.
9828 unification of code in functions tempfilename() and tempfile():
9829 function tempnam() is defined in Visual Studio 6.0 and .NET
9831 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9833 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9834 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9835 - removed compiler command line option /WX: Treats all warnings as errors
9836 - update a list of source files, included into the project
9838 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9839 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9840 changed project type to Generic Project so that can be correcly converted to VS.NET project
9842 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9844 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9846 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9848 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9849 added return 0 statements after assert() to make compiler happy
9851 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9852 added newline in the def file to keep MSC compiler satisfied
9854 * sdcc/src/z80/gen.c:
9855 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9856 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9857 - solved MSC error in function aopDump()
9859 * sdcc_vc.h: define PREFIX as "\\sdcc"
9861 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9862 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9901 2002-03-28 Johan Knol <johan AT balder>
9903 * src/SDCCval.c: fixed bug #532436
9905 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9907 Added "char *Processor" field to the port structure.
9910 Added -p option. Allows port dependent processor to be specified.
9913 Initialized the new field char *Processor field to NULL in all ports
9916 Compiler generated registers for interrupt context saving
9917 were not getting allocated.
9919 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9922 Fixed left shift. Will promote the left side of a left shift
9923 if a) left shifting more than size of operand or b) when assigned
9924 to something size > size of left side
9926 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9928 tons of changes. Register allocation has been
9929 rewritten. Added customization for the various PICs. Flow
9930 analysis is restructured. ...
9936 Added. device.c is a PIC port hack to accomodate variations
9939 2002-03-13 Michael Hope <michaelh AT vroom>
9941 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9943 2002-03-04 johanknol <johanknol AT manik>

9952 * /device/include/mcs51reg.h:
9953 ds89c420 register definition update
9955 2002-03-03 <johan AT FRIJA>
