113 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
116 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
118 * src/.version: increased version number to 2.5.5
119 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
120 linking is done manually in pic16 port's _linkEdit,
121 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
122 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
123 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
124 allocate asmop as AOP_ACC,
125 (aopForRemat): added parameter 'bool result' in function declaration,
126 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

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

2586 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2588 * device/lib/printf_large.c: removed inline assembly for portability and
2589 readability. Use printf_fast if speed or size are more important.
2590 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2591 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2593 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2595 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2596 prevent compiler warning
2598 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2600 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2601 moved to level 0 and declared as static. Also they are explicit
2602 placed in access bank. This was necessery because some times they
2603 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2604 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2605 optimizations. Currently only compare to unsigned char is implemented,
2606 * src/pic16/gen.c: added fReturnIdx array,
2607 * (struct resolvedIfx) is moved to gen.h and made public,
2608 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2609 * (aopForSym): added an optimization to directly store in stack of
2610 the operand of a SEND iCode,
2611 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2612 but as registers instead (AOP_REG) using the fReturnIdx array,
2613 * (pic16_freeAsmop): remove the freed register from the
2614 _G.sregsAlloc field,
2615 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2616 a compare of 'WREG',
2617 * (pic16_popGetTempRegCond): changed function prototype, now
2618 function takes also a bitVector argument v which holds the current
2619 set of registers that are allocated for stack access by aopForSym,
2620 registers allocated in aopForSym for accessing stack symbols are not
2621 any more part of the functions usedRegs field,
2622 * (genCall): some times aopOp is called for a stack variable to be
2623 send, aopForSym might perform the push, if this is true make sure
2624 that genCall doesn't push the variable twice by testing _G.resDirect,
2625 * (genFunction): changed testing for unspecified interrupt number
2626 from 256 to INTNO_UNSPEC,
2627 * modified selection scheme of frame pointer generation. Previously
2628 if function did use local registers a frame pointer was generated,
2629 now a frame pointer is generated only if function has arguments
2630 (that need PLUSW2 register access), or has stack arguments, or the
2631 compiler is not instructed to omit the frame pointer,
2632 * (genEndFunction): before restoring local registers that were saved
2633 in the function preamble, also restore the registers that *might*
2634 have been allocated for stack access,
2635 * (genRet): removed some old comments,
2636 * (genCmp, the active (RN's) version): added a call to the
2637 pic16_genCmp_special function to perform the compare with a more
2638 robust and optimized way,
2639 * (genInline): a feature has been added in inline code generation,
2640 which allows a wildcard variable substitution when writing inline
2641 assembly. Code is incomplete and experimental therefore undocumented,
2642 * (genCast): changed order of aopOp for result and right to allow
2643 aopForSym to directly load the result if possible,
2644 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2645 perform an optimized compare on some selected special occasions,
2646 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2647 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2648 generate an IVT any more,
2649 * src/pic16/main.c (pic16_optionsTable): added command line option
2651 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2652 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2654 * src/pic16/NOTES: Raphael Neider added in list of active developers
2655 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2656 jumptable_end to prevent bug #,
2657 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2658 inCond and outCond fields,
2659 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2660 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2661 turn off register spilling,
2662 * (packRegsForOneUse): synced with other ports' versions although it
2663 is not used currently,
2664 * (pic16_packRegisters): added an optimization while reading
2665 structure bitfields, some registers may be saved (malloc code is
2666 decreased by 80 bytes)
2668 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2670 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2671 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2672 this can be optimized more?
2674 2005-03-10 Raphael Neider <rneider AT web.de>
2676 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2677 genNearPointerGet): (hopefully) fixed access to bitfields via
2678 pointers (p->bitN = x; and x = p->bitN; failed)
2680 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3004 access stack and frame pointers. They are initially assigned to
3005 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3006 accessing SFRs. Updated all occurences of modification of stack or
3007 frame pointer in gen.c and pcode.c,
3008 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3009 assigning of a literal value to pointers,

3313 generated for switch statements. For now you need to set the
3314 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3315 Now 4 algorithms for mcs51 jumptable generation are used:
3316 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3350 * added libc directory. The current version of LibC contains string
3351 functions, ctype functions and macros and some functions of the
3352 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3353 be extensively tested in the future. Standard disclaimer here.
3354 Library is not automatically build yet. But one can build it by

3366 * (pic16_storeForReturn): optimized return of 0,
3367 * (genCmp): experimental code for new genCmp which uses PIC18's
3368 special compare&skip instructions. Initial tests fail some times
3369 with variables grater than 1 byte in size, so new code is disabled,
3370 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3372 * (genCast): began a fix to optimize the casting of a bit to another
3373 bit, now assigning a bitfield to another bitfield will fail, sorry,

3387 registers when it shouldn't,
3388 * src/pic16/ralloc.c (allocReg): add preliminary support for
3389 supporting a limited set of temporary registers,
3391 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6396 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6398 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6399 loaded with the linker search paths (-L arguments) and the libraries
6400 to be linked with the current source (-l arguments). Changes
6401 currently will affect only the pic16 port.
6402 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6403 include path the port specific paths and port specific libraries,
6404 * gplink command now contains the $3 argument,
6405 * src/pic16/device.h,
6406 * src/pic16/device.c,: structure PIC_device is made public and

6422 Documenting changes from previous commits.
6423 * configure.in (version 1.56),
6424 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6425 when generating output files to configure the pic16 library,
6426 but now I've commented it out, since gputils aren't installed in the
6427 SF compile farm, so library won't compile
6429 * device/lib/Makefile.in (version 1.56): initially I've added in
6430 target 'all' the prerequestive 'model-pic16' so it compiled the
6431 pic16 library, but now I've commented it out for the same reasons
6433 * added targets 'model-pic16' and 'objects-pic16' to compile the
6435 * added target 'port-specific-objects-pic16' to handle the
6436 generated libraries and copy them into the build/ directory
6437 * added target 'clean-intermediate-pic16' to clean intermediate
6438 files into pic16 directory
6439 * in target 'installdirs' added line to create directory pic16 in
6440 the installation path

6443 added lines to copy all header files to installation path,
6444 * in target 'installdirs' added line create directory for pic16
6445 headers in the installation path

6461 option so that it actually works. Made it specific to the z80, since
6462 the gbz80 doesn't have these kinds of I/O ports.
6464 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6466 * device/include/z180.h,

6490 via literal number. The symbol is placed in the corresponding
6491 position of the data ram
6492 * (pic16_dump_section): relocatable and absolute uninitialized
6493 data are now emitted in sorted order to reduce section naming,
6494 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6495 weren't marked as being in the access bank,
6497 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6499 Added portion of GNU PIC Library under the directory
6500 device/include/pic16 and device/lib/pic16. These files
6501 contain the declarations of SFRs for the PIC18Fxx2 devices.
6502 The directory is initialized via configure from toplevel.

6572 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
6573 UPPER for immediate operands,
6574 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6576 * src/pic16/peeph.def: all peepholes with movff are commented out,
6577 because there is a problem in the pcode peep optimizer,
6578 * src/pic16/ralloc.c: the register allocator can now reuse local
6579 function symbols for another function. This saves register usage.
6580 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6582 Added file src/pic16/NOTES with information about program writing on
6583 the current port version.

6671 include information about variables allocated to the overlay
6674 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6676 * as/mcs51/lkmain.c: Help about -Y option

6686 LEFT_OP (left shift)
6688 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6690 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6691 (default behaviour).
6693 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6695 A python script to validate compiler diagnostic messages. It can be
6696 used to verify that sdcc complains about bad c source code and
6697 gives a good location of the error.
6698 * support/valdiag/Makefile,
6699 * support/valdiag/valdiag.py,
6700 * support/valdiag/tests/*
6702 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6717 Bug reported from Jesus Calvino-Fraga
6719 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6721 * sdcc.spec: updated
6722 * device/include/Makefile.in: don't install CVS directories
6723 * device/lib/Makefile.in: added removal of CVS directories after install
6724 * doc/Makefile: fixed install, added local_icons
6725 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6726 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6727 * src/ds390/gen.c (genRightShift): fixed bug #870788
6728 * src/SDCCast.c (decorateType): fixed bug #870781
6730 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6732 PIC16 port related changes:
6733 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6734 added variable stackPos,
6736 * gen.c: genCall, assignResultValue: added support for
6737 pushing/retrieving function parameters to/from stack,
6738 genFunction,genEndFunction: setup stack frame for the
6740 genAddrOf: will be changed according to bug 863624
6742 * added files genutils.c and genutils.h which contain gen*
6743 debugged and optimised functions extracted from gen.c
6745 * glue.c: added variable 'externs' which holds extern symbols,
6746 pic16emitRegularMap: is modified to properly handle relocatable
6747 symbols under the new scheme,
6748 pic16createInterruptVect: is modified
6749 pic16printPublics: is modified to emit 'global' assembler directives,
6750 added pic16_printExterns to print extern symbols,
6751 pic16glue: initializes stack/frame pointer in the beginning of
6752 the assembly output. Temporary hack, will be corrected later,
6753 because gplink yet does not support stack and SDCC does not
6754 yet support a type of crt0.o object to create the final binary.
6756 * Removed many lines that contain 8051 legacy code.
6757 * The code is finally placed under a 'code' directive.
6758 * Added port specific options.
6760 * _process_pragma: simplified since now we do not need *special*
6761 include file to define SFR registers. But a separate header
6762 will be needed. This will be developed later.
6763 * _pic16_parseOptions: added, parses port specific options:
6764 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6765 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6766 --preplace-udata-with=
6768 * _pic16_setDefaultOptions: modified to initialize section names,
6769 but hack is temporarly out of order since it needs improvement.
6770 * _pic16_genAssemblerPreamble: configuration words are emitted by
6771 their address instead of their name. This part is incomplete and
6772 supports only the 18Fxx2 devices. Other devices will emit an error
6773 during assembly since they do not contain the same set of config
6775 * _pic16_genIVT: is modified,
6777 * pcode.c: added definitions for some hardware registers that are needed
6779 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6780 All PCI entries are updated. Now LFSR is supported.
6781 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6782 * added pic16_newpCodeOpLit2 to support instructions with
6783 two literal arguments
6784 * pic16_pCode2str: corrected code that emits assembler instructions
6785 with two literal operands and those that have an access bit modifier
6786 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6787 this fixes a bug which caused some labels to be lost, when an
6788 assembler directive was added, i.e. banksel,
6789 * pic16_FixRegisterBanking: improved logic that causes the insertion
6791 * InlineFunction: functions that are called once, are not any more
6792 inlined. This can be a port option in the future,
6794 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6796 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6797 hold the corresponding uninitialized symbols,
6798 * pic16_allocProcessorRegister: registers have explicit marked the
6800 * pic16_allocInternalRegister: registers are explicit marked as
6802 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6803 processing list, so bit registers were lost,
6806 * ralloc.h: added field 'accessBank' and original symbol operand
6807 in register definition,
6808 * removed the field isMapped from register definition,
6810 ** Several functions have been removed from various sources:
6811 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6812 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6813 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6814 pic16_assignRelocatableRegisters
6816 ** others have been introduced:
6817 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6818 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6820 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6822 * support/scripts/inc2h.pl: changed definition of BIT_AT
6823 to emit 'sbit at' instead of 'bit at'. This was a request.
6825 PIC16 port related preliminary changes:
6826 * gen.c: prefixed function popRegFromString with
6827 pic16_ and all references to it corrected
6828 * pcode.c: all pic16_pc_* hardware registers prefixed
6829 with underscore (_),
6830 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6831 * ralloc.c: newReg(): when register is REG_SFR then
6832 set address to rIdx,
6833 pic16_allocProcessorRegister(): marks register wasUsed=0
6834 pic16_writeUsedRegs(): added a call to assign processor
6835 registers via pic16_assignFixedRegisters
6837 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6839 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6840 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6841 variables in unused register banks. Also the SSEG is placed
6842 wherever there is enough space for it, and IDATA can be anywhere
6843 in internal RAM. For now compile using -Wl-Y[stack_size].
6844 The mem file is different for this option as well, since it
6845 makes no sense of talking about DSEG lenght.
6847 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6849 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6850 in certain cases, e.g. when ROM assignment, patch provided
6851 from Albert den Haan.
6853 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7855 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7856 fetching of the pointer
7857 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7858 copied from genNearPointerSet()
7859 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7860 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7874 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7876 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7877 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7878 type for bits was changed. It resulted in bit variables becoming
7879 global, which is not permitted in PIC 14 assembly output.
7881 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7896 A few small changes that speed up the peephole optimizer.
7900 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7902 Try to make the peephole optimizer smarter by maintaining
7903 an association between the assembly source code and the
7904 iCodes that originated them. Put this information to use
7905 with a new peephole rule condition "notVolatile" so that
7906 the rules can be aggressive yet still safe.
7911 * src/mcs51/peeph.def
7913 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7917 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7918 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7919 if the left or right operand symbols have the accuse flag set.
7921 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7923 Changed the type of the result of the ! (NOT) operator to char;
7924 previously it returned the same type as the source. This allows
7925 us to eliminate all the genFloatNot functions (all of its target
7926 implementations were very buggy) since !float can use the same

7938 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7939 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7940 during interrupts. Ensure WSAVE is located at a shared bank address.
7941 2. Fixed page selection in some places
7942 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7943 the registers name strings.
7944 4. Fixed "signed / unsigned compare" compiler warnings.
7945 5. The PIC port manages its own allocation of the general purpose
7946 registers, but makes no attempt to reuse them. As a result when
7947 compiling it soon runs out of general purpose registers. Some
7948 additional code was added to the files pcode.c and device.c to walk
7949 through the function call tree and rename the registers so that they
7959 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7960 genPlus() & genMinus() when the result is the same as left or right

7966 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7968 Made bitfield a distinct type from bit so that bitfields
7969 convert as per ANSI C and bits retain their traditional
7970 boolean style behaviour. Implemented bitfield support in
7978 * src/ds390/gen.c: bit v bitfield split
7979 * src/z80/gen.c: New support for bitfields
7980 * support/regression/tests/bitfields.c: reenabled z80,
7983 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7985 Rules 246.x, 247.x relate to bitfields, the others speed up
7986 access to xdata mapped I/O devices.
7988 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7990 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7992 Cleaned up genPackBits and genUnpackBits and added two helper
7993 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7994 for literal assignments in genPackBits (thanks to Frieder for
8000 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8002 Fixed bug #748310 (pointer to function type mishandled when the
8003 function name is omitted). Also fixed a SIGSEGV when a function
8004 attribute (reentrant, etc) is used on a non-function or on a
8005 function but misplaced before the parameter list.
8007 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8009 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8010 * support/Util/SDCCerr.h,

8032 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8034 Made the constant following the "interrupt" keyword optional. If
8035 omitted, the function will not automatically be given an entry
8036 in the interrupt vector table (similar to #pragma NOIV, but
8037 less syntacticly kludgy). The interrupt number is also now
8038 range checked. Also fixed a bug in the high order bit example

8568 added if/endif conditional macros to remove options help
8569 messages from optionsTable when a port is not configured, added
8570 support for the PIc16 port in the ports table, when executing
8571 the compiler with no port specified on command line, a default
8572 port is selected with the new macro DEFAULT_PORT which is
8573 defined in port.h, in setDefaultOptions() linkOptions is removed
8574 from initialization assignment, since now it is a set,
8575 parseCmdLine uses setParseWithComma for linkOptions, in
8576 linkEdit() linkOptions are accessed with new function indexSet()
8577 which returns the i'th item of a set variable. See SDCCset.c, in
8578 linkEdit() when calling buildCmdLine(), added linkOptions as
8579 last argument. Now users can pass arguments to gplink via the
8580 -Wl option, main() uses pic16glue() to glue up pic16 programs

8593 * src/pic16/main.c: __config directives are commented out to stop
8594 gpasm complaining and test the linkage with gplink, _linkCmd and
8595 _asmCmd changed to be more gplink and gpasm friendly
8596 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8597 produced an error when parsed, peep rule 12 is added to utilize
8598 movff, but it is commented out since the pCode does not support
8599 yet a command with 2 address arguments
8601 2003-05-18 <johan AT balder>
8603 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8622 Fixed so you can set breakpoints prior to run, run does not stop
8623 on entry now. Add tbreak. Other enhancements and fixes for use
8626 2003-05-12 Borut Razem <borut.razem AT siol.net>
8628 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8630 2003-05-11 Borut Razem <borut.razem AT siol.net>
8632 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9640 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9641 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9642 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9644 2003-01-04 <johan AT balder>
9646 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9648 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9661 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9662 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9664 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9666 * in \sdcc\as\mcs51\ changed these files in order to create an
9667 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9668 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9669 following files to include the previous two files: aslink.dsp,
9670 Makefile.aslink, Makefile.bcc, and Makefile.in.
9672 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9673 .adb instead of .cdb
9675 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9677 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9678 value from option --iram-size.
9680 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9682 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9685 2002-09-18 <wiml AT hhhh.org>
9687 * SDCClrange.h: exposed setFromRange() and setToRange()
9688 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9689 packRegsForAccUse() (bug 542397)
9690 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9691 multiple times and emitting the fetch operations more than once
9692 added aopGetUsesAcc() function to allow binary operators to
9693 fetch their operands in the correct order; made genMinus() emit
9694 compact code for X = LITERAL - Y
9696 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9697 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9698 sprintf() in line 1267.
9700 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9701 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9704 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9705 Changes to aslink (All the changes are marked with 'JCF'):
9707 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9710 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9711 area BSEG. Also moves, if possible, the DATA area down into the internal
9712 ram so more space is available.
9714 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9717 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9718 not bytes. Function summary() which creates a memory usage summary
9719 file with extension .mem. Reports of overlaping stack and small stack
9720 size. If the space for the stack is less than 16 bytes aslink trows a
9723 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9724 the 8051. Option 'y' for memory summary output file.
9726 Changes to sdcc (All the changes are marked with 'JCF'):
9728 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9730 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9731 overlaying area for it (uses RegBankUsed[4]).
9733 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9734 bank zero as used by default. By default aslink locates the stack
9735 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9736 the creation of the .mem file. Delegates the allocation of data area
9737 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9738 the begining of the stack area to aslink.
9740 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9741 glue() in SDCCglue.c creates an area for it.
9743 2002-09-03 Borut Razem <borut.razem AT siol.net>
9744 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9745 sdcc/src/pic/glue.c:
9746 introduced atexit() handler for teporay files removal in case of
9747 errors, assertions, ...
9749 2002-08-29 Borut Razem <borut.razem AT siol.net>
9750 * sdcc/support/cpp2/auto-host_vc_in.h:
9751 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9752 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9753 Maybe there is a similar problem with BORLANDC? It should be checked!
9755 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9756 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9757 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9758 was not executed, and the compiler (cl) launched a warning:
9759 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9761 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9762 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9764 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9765 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9767 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9768 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9769 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9770 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9771 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9772 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9773 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9774 - added Release configuration in VS projects
9775 - review of compiler an linker options
9776 - VC .exe files are generated in bin_vc directory, not to interfere
9777 with binaries generated from other projects (cygwin, mingw, bcc ...)
9779 * sdcc/src/yacc.dsp: added
9781 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9782 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9783 and insert the version number definitions from .version
9785 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9787 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9788 added - genarate auto-host.h using auto-host_vc_in.h as template
9791 removed from CVS, generated automatically
9793 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9794 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9796 2002-08-11 Borut Razem <borut.razem AT siol.net>
9797 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9799 2002-08-10 Borut Razem <borut.razem AT siol.net>
9800 * src/SDCCmain.c (main):
9801 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9802 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9803 The consequence was that some temporary files were not removed.
9806 unification of code in functions tempfilename() and tempfile():
9807 function tempnam() is defined in Visual Studio 6.0 and .NET
9809 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9811 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9812 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9813 - removed compiler command line option /WX: Treats all warnings as errors
9814 - update a list of source files, included into the project
9816 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9817 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9818 changed project type to Generic Project so that can be correcly converted to VS.NET project
9820 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9822 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9824 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9826 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9827 added return 0 statements after assert() to make compiler happy
9829 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9830 added newline in the def file to keep MSC compiler satisfied
9832 * sdcc/src/z80/gen.c:
9833 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9834 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9835 - solved MSC error in function aopDump()
9837 * sdcc_vc.h: define PREFIX as "\\sdcc"
9839 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9840 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9843 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9844 - Rewrote the register banking algorithm.
9845 - Added pCode live-range analysis to registers (for now, only non-used and
9846 singly-used registers optimized away)
9848 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

9879 2002-03-28 Johan Knol <johan AT balder>
9881 * src/SDCCval.c: fixed bug #532436
9883 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9885 Added "char *Processor" field to the port structure.
9888 Added -p option. Allows port dependent processor to be specified.
9891 Initialized the new field char *Processor field to NULL in all ports
9894 Compiler generated registers for interrupt context saving
9895 were not getting allocated.
9897 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9900 Fixed left shift. Will promote the left side of a left shift
9901 if a) left shifting more than size of operand or b) when assigned
9902 to something size > size of left side
9904 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9906 tons of changes. Register allocation has been
9907 rewritten. Added customization for the various PICs. Flow

10014 * sdcc/src/SDCCloop.c:
10015 Previous fix was not good. basic blocks that have "break" or "return" are
10016 not really partof a loop , but live ranges used in these blocks should
10017 be live thru the entire loop, so set partOfLoop but don't add them to
