2693 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2695 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2696 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2698 One basic decision: e.g. src/clean.mk includes further files. In order
2699 to make this work there are two solutions:
2700 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2701 run configure on them. This way they can use
2702 'include $(srcdir)/port-clean.mk'
2703 - always include clean.mk by the Makefile at the same level. To avoid
2704 that `make clean` tries to include and build Makefile.dep the
2705 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2706 implemented, because now even `make uninstall` doesn't create
2707 Makefile.in. clean.mk could be eliminated by pasting it in
2710 * debugger/mcs51/Makefile.in: build own objects from library sources
2711 (SLIB, SDCC) in current directory
2713 * configure, configure.in: renamed --disable-device-lib-build in
2714 --disable-device-lib; added --enable-doc, the required tools are
2715 searched by configure; added result message; the toolchain for the
2716 belonging ports are now only built, if the port is enabled.
2718 * support/regression/*: all output is written in directory gen, because
2719 the fwk and ports directories don't livet in the build tree using vpath
2721 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2722 --disable-device-lib, added --enable-doc, added section VPATH
2724 * sim/ucsim/configure.in,
2725 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2726 z80 are enabled by default
2728 2006-04-24 Raphael Neider <rneider AT web.de>
2730 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2731 to config word, "pic14_"-prefixed some extern functions
2732 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2733 config word has been found
2734 * src/pic/device.h: added prototypes
2735 * src/pic/pcode.c: added "pic14_"-prefix where needed

3024 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3025 linking is done manually in pic16 port's _linkEdit,
3026 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3027 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3028 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3029 allocate asmop as AOP_ACC,
3030 (aopForRemat): added parameter 'bool result' in function declaration,
3031 (pic16_aopGet): return AOP_ACC when accessing WREG,
3032 (pic16_popGetTempReg): minor modification,
3033 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3034 'pic16_allocWithIdx',
3035 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3036 calling function in absolute addresses,
3037 (genAssign): take into account AOP_ACC asmop,
3038 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3039 * src/pic16/pcoderegs.c: some debug functions and lines added,
3040 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3041 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3043 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3044 call to allocReg, not by manually allocating a new one,
3045 (pic16_assignRegisters): now before going through the register
3046 allocating functions mark all registers as free. This eliminates some
3047 side effects resulting from peephole parser done earlier in the backbone
3049 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3070 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3071 (aopForSym, aopOp): increment asmop.allocated if reused,
3072 (freeAsmop): decrement asmop.allocated and check for zero instead of
3074 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3075 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

3099 2006-03-06 Borut Razem <borut.razem AT siol.net>
3101 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3102 made the linker quiet
3104 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3106 * src/pic16/gen.c (genPcall): fixed bug #1443644
3107 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3108 which dumps before the function entry point a data byte which represents
3109 the number of the local variables used by the specified function, added
3110 'xinst' for initial support for Extended Instruction Support,
3111 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3112 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3113 port->fun_prefix anymore (may change later),
3114 (genFunction, genEndFunction): do not store/restore local registers for
3115 _main (this should take care the --main-return command line option in
3117 (genOr): removed some legacy pic-port instructions,
3118 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3119 performing operations with SFR's causes data to be written more than
3120 once to each SFR. Perhaps SFRs should be handled in special cases...
3121 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3123 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3124 into account for stack starting position,

3126 --extended or -y for Extended Instruction Support,
3127 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3128 (deassignLRs): *** perhaps the most important change, old 'for' code
3129 (commented out for reference), didn't account for some registers which
3130 were left marked 'not free' after a pointer operation. The change
3131 reduces register usage a lot in some cases

5489 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5491 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5493 * device/lib/printf_large.c: removed inline assembly for portability and
5494 readability. Use printf_fast if speed or size are more important.
5495 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5496 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5498 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5500 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5501 prevent compiler warning
5503 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5505 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5506 moved to level 0 and declared as static. Also they are explicit
5507 placed in access bank. This was necessery because some times they
5508 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5509 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5510 optimizations. Currently only compare to unsigned char is implemented,
5511 * src/pic16/gen.c: added fReturnIdx array,
5512 * (struct resolvedIfx) is moved to gen.h and made public,
5513 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5514 * (aopForSym): added an optimization to directly store in stack of
5515 the operand of a SEND iCode,
5516 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5517 but as registers instead (AOP_REG) using the fReturnIdx array,
5518 * (pic16_freeAsmop): remove the freed register from the
5519 _G.sregsAlloc field,
5520 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5521 a compare of 'WREG',
5522 * (pic16_popGetTempRegCond): changed function prototype, now
5523 function takes also a bitVector argument v which holds the current
5524 set of registers that are allocated for stack access by aopForSym,
5525 registers allocated in aopForSym for accessing stack symbols are not
5526 any more part of the functions usedRegs field,
5527 * (genCall): some times aopOp is called for a stack variable to be
5528 send, aopForSym might perform the push, if this is true make sure
5529 that genCall doesn't push the variable twice by testing _G.resDirect,
5530 * (genFunction): changed testing for unspecified interrupt number
5531 from 256 to INTNO_UNSPEC,
5532 * modified selection scheme of frame pointer generation. Previously
5533 if function did use local registers a frame pointer was generated,
5534 now a frame pointer is generated only if function has arguments
5535 (that need PLUSW2 register access), or has stack arguments, or the
5536 compiler is not instructed to omit the frame pointer,
5537 * (genEndFunction): before restoring local registers that were saved
5538 in the function preamble, also restore the registers that *might*
5539 have been allocated for stack access,
5540 * (genRet): removed some old comments,
5541 * (genCmp, the active (RN's) version): added a call to the
5542 pic16_genCmp_special function to perform the compare with a more
5543 robust and optimized way,
5544 * (genInline): a feature has been added in inline code generation,
5545 which allows a wildcard variable substitution when writing inline
5546 assembly. Code is incomplete and experimental therefore undocumented,
5547 * (genCast): changed order of aopOp for result and right to allow
5548 aopForSym to directly load the result if possible,

6217 Adding support for replacing ljmps with sjmps in jumptables
6218 generated for switch statements. For now you need to set the
6219 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6220 Now 4 algorithms for mcs51 jumptable generation are used:
6221 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6222 addresses loaded pc-relative for up to 112 cases and stack-pushing
6223 target addresses loaded with offset from dptr for up to 256 cases.

6253 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6255 * added libc directory. The current version of LibC contains string
6256 functions, ctype functions and macros and some functions of the
6257 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6258 be extensively tested in the future. Standard disclaimer here.
6259 Library is not automatically build yet. But one can build it by
6260 invoking 'make' inside the libc directory.

6271 * (pic16_storeForReturn): optimized return of 0,
6272 * (genCmp): experimental code for new genCmp which uses PIC18's
6273 special compare&skip instructions. Initial tests fail some times
6274 with variables grater than 1 byte in size, so new code is disabled,
6275 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6277 * (genCast): began a fix to optimize the casting of a bit to another
6278 bit, now assigning a bitfield to another bitfield will fail, sorry,

6287 and 1 for banking instruction,
6288 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6289 caused stop processing pCodes after a inline assembly block,
6290 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6292 registers when it shouldn't,
6293 * src/pic16/ralloc.c (allocReg): add preliminary support for
6294 supporting a limited set of temporary registers,
6296 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6302 (genFunction): optimize RECEIVE iCodes in reentrant functions
6304 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9304 loaded with the linker search paths (-L arguments) and the libraries
9305 to be linked with the current source (-l arguments). Changes
9306 currently will affect only the pic16 port.
9307 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9308 include path the port specific paths and port specific libraries,
9309 * gplink command now contains the $3 argument,
9310 * src/pic16/device.h,
9311 * src/pic16/device.c,: structure PIC_device is made public and

9327 Documenting changes from previous commits.
9328 * configure.in (version 1.56),
9329 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9330 when generating output files to configure the pic16 library,
9331 but now I've commented it out, since gputils aren't installed in the
9332 SF compile farm, so library won't compile
9334 * device/lib/Makefile.in (version 1.56): initially I've added in
9335 target 'all' the prerequestive 'model-pic16' so it compiled the
9336 pic16 library, but now I've commented it out for the same reasons
9338 * added targets 'model-pic16' and 'objects-pic16' to compile the
9340 * added target 'port-specific-objects-pic16' to handle the
9341 generated libraries and copy them into the build/ directory
9342 * added target 'clean-intermediate-pic16' to clean intermediate
9343 files into pic16 directory
9344 * in target 'installdirs' added line to create directory pic16 in

9348 added lines to copy all header files to installation path,
9349 * in target 'installdirs' added line create directory for pic16
9350 headers in the installation path

9590 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9591 LEFT_OP (left shift)
9593 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9595 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9596 (default behaviour).
9598 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9600 A python script to validate compiler diagnostic messages. It can be
9601 used to verify that sdcc complains about bad c source code and
9602 gives a good location of the error.
9603 * support/valdiag/Makefile,
9604 * support/valdiag/valdiag.py,
9605 * support/valdiag/tests/*

9618 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9620 * src/common.h: added ifndef/define/endif macros
9621 around the header file.
9622 Bug reported from Jesus Calvino-Fraga
9624 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9626 * sdcc.spec: updated
9627 * device/include/Makefile.in: don't install CVS directories
9628 * device/lib/Makefile.in: added removal of CVS directories after install
9629 * doc/Makefile: fixed install, added local_icons
9630 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9631 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9632 * src/ds390/gen.c (genRightShift): fixed bug #870788

9635 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9637 PIC16 port related changes:
9638 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9639 added variable stackPos,
9641 * gen.c: genCall, assignResultValue: added support for
9642 pushing/retrieving function parameters to/from stack,
9643 genFunction,genEndFunction: setup stack frame for the
9645 genAddrOf: will be changed according to bug 863624
9647 * added files genutils.c and genutils.h which contain gen*
9648 debugged and optimised functions extracted from gen.c
9650 * glue.c: added variable 'externs' which holds extern symbols,
9651 pic16emitRegularMap: is modified to properly handle relocatable
9652 symbols under the new scheme,
9653 pic16createInterruptVect: is modified
9654 pic16printPublics: is modified to emit 'global' assembler directives,
9655 added pic16_printExterns to print extern symbols,
9656 pic16glue: initializes stack/frame pointer in the beginning of
9657 the assembly output. Temporary hack, will be corrected later,
9658 because gplink yet does not support stack and SDCC does not
9659 yet support a type of crt0.o object to create the final binary.
9661 * Removed many lines that contain 8051 legacy code.
9662 * The code is finally placed under a 'code' directive.
9663 * Added port specific options.
9665 * _process_pragma: simplified since now we do not need *special*
9666 include file to define SFR registers. But a separate header
9667 will be needed. This will be developed later.
9668 * _pic16_parseOptions: added, parses port specific options:
9669 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9670 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9671 --preplace-udata-with=
9673 * _pic16_setDefaultOptions: modified to initialize section names,
9674 but hack is temporarly out of order since it needs improvement.
9675 * _pic16_genAssemblerPreamble: configuration words are emitted by
9676 their address instead of their name. This part is incomplete and
9677 supports only the 18Fxx2 devices. Other devices will emit an error
9678 during assembly since they do not contain the same set of config
9680 * _pic16_genIVT: is modified,
9682 * pcode.c: added definitions for some hardware registers that are needed
9684 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9685 All PCI entries are updated. Now LFSR is supported.
9686 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9687 * added pic16_newpCodeOpLit2 to support instructions with
9688 two literal arguments
9689 * pic16_pCode2str: corrected code that emits assembler instructions
9690 with two literal operands and those that have an access bit modifier
9691 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9692 this fixes a bug which caused some labels to be lost, when an
9693 assembler directive was added, i.e. banksel,
9694 * pic16_FixRegisterBanking: improved logic that causes the insertion
9696 * InlineFunction: functions that are called once, are not any more
9697 inlined. This can be a port option in the future,
9699 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9701 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9702 hold the corresponding uninitialized symbols,
9703 * pic16_allocProcessorRegister: registers have explicit marked the
9705 * pic16_allocInternalRegister: registers are explicit marked as
9707 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9708 processing list, so bit registers were lost,
9711 * ralloc.h: added field 'accessBank' and original symbol operand
9712 in register definition,
9713 * removed the field isMapped from register definition,
9715 ** Several functions have been removed from various sources:
9716 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9717 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9718 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9719 pic16_assignRelocatableRegisters
9721 ** others have been introduced:
9722 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9723 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9725 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9727 * support/scripts/inc2h.pl: changed definition of BIT_AT
9728 to emit 'sbit at' instead of 'bit at'. This was a request.
9730 PIC16 port related preliminary changes:
9731 * gen.c: prefixed function popRegFromString with
9732 pic16_ and all references to it corrected
9733 * pcode.c: all pic16_pc_* hardware registers prefixed
9734 with underscore (_),
9735 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9736 * ralloc.c: newReg(): when register is REG_SFR then
9737 set address to rIdx,
9738 pic16_allocProcessorRegister(): marks register wasUsed=0
9739 pic16_writeUsedRegs(): added a call to assign processor
9740 registers via pic16_assignFixedRegisters
9742 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9744 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9745 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9746 variables in unused register banks. Also the SSEG is placed
9747 wherever there is enough space for it, and IDATA can be anywhere
9748 in internal RAM. For now compile using -Wl-Y[stack_size].
9749 The mem file is different for this option as well, since it
9750 makes no sense of talking about DSEG lenght.
9752 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9754 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9755 in certain cases, e.g. when ROM assignment, patch provided
9756 from Albert den Haan.

9997 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9999 * src/SDCCast.c (decorateType): disabled a transformation I added in
10000 revision 1.188 (access to fields of a structure at an absolute address);
10001 it breaks with bitfields, extern declarations, and gcse analysis.
10002 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10003 could be assigned through a pointer, so don't complain.
10004 * src/SDCCast.c (astErrors),
10006 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
10008 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

10014 pre-processor macro, i.e. -DMCU=p18f452
10015 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
10016 and modified to handle 'cast' icode similarly to '=' icode

10664 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10666 Fixed bug #621531 (const & volatile confusion in the type chain).
10667 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10668 refer to the const or volatile state of the pointer itself.
10680 * src/pic16/ralloc.c
10681 * support/regression/tests/const.c
10683 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

10745 and JUMPTABLE iCodes properly now (worked by accident before)
10746 * src/mcs51/gen.c (leftRightUseAcc),
10747 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10748 iCode properly now. Use getSize instead of nRegs since a & b

10763 copied from genNearPointerSet()
10764 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10765 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10766 If they pop r0/r1 they must be called in the opposite order than aopOp().
10767 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10768 (resp. --stack-auto), prepared for --xstack
10770 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10772 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10774 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10779 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10781 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10782 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10783 type for bits was changed. It resulted in bit variables becoming
10784 global, which is not permitted in PIC 14 assembly output.
10786 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10788 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10790 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10792 Z80 and MCS51 linkers complaint if a public symbol is defined
10793 in more than one library module:

10799 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10801 A few small changes that speed up the peephole optimizer.
10805 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10807 Try to make the peephole optimizer smarter by maintaining
10808 an association between the assembly source code and the
10809 iCodes that originated them. Put this information to use
10810 with a new peephole rule condition "notVolatile" so that
10811 the rules can be aggressive yet still safe.
10816 * src/mcs51/peeph.def
10818 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10822 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10823 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10824 if the left or right operand symbols have the accuse flag set.
10826 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10828 Changed the type of the result of the ! (NOT) operator to char;
10829 previously it returned the same type as the source. This allows
10830 us to eliminate all the genFloatNot functions (all of its target
10831 implementations were very buggy) since !float can use the same
10834 * src/SDCCicode.c (ast2iCode): ! returns char
10835 * src/mcs51/gen.c (genNot, genNotFloat),
10836 * src/ds390/gen.c (genNot, genNotFloat),
10837 * src/z80/gen.c (genNot, genNotFloat),
10838 * src/pic/gen.c (genNot, genNotFloat),
10839 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10843 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10844 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10845 during interrupts. Ensure WSAVE is located at a shared bank address.
10846 2. Fixed page selection in some places
10847 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10848 the registers name strings.
10849 4. Fixed "signed / unsigned compare" compiler warnings.
10850 5. The PIC port manages its own allocation of the general purpose
10851 registers, but makes no attempt to reuse them. As a result when
10852 compiling it soon runs out of general purpose registers. Some
10853 additional code was added to the files pcode.c and device.c to walk
10854 through the function call tree and rename the registers so that they
10864 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10865 genPlus() & genMinus() when the result is the same as left or right
10867 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10871 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10873 Made bitfield a distinct type from bit so that bitfields
10874 convert as per ANSI C and bits retain their traditional
10875 boolean style behaviour. Implemented bitfield support in
10883 * src/ds390/gen.c: bit v bitfield split
10884 * src/z80/gen.c: New support for bitfields
10885 * support/regression/tests/bitfields.c: reenabled z80,
10888 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10890 Rules 246.x, 247.x relate to bitfields, the others speed up
10891 access to xdata mapped I/O devices.
10893 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10895 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10897 Cleaned up genPackBits and genUnpackBits and added two helper
10898 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10899 for literal assignments in genPackBits (thanks to Frieder for
10905 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10907 Fixed bug #748310 (pointer to function type mishandled when the
10908 function name is omitted). Also fixed a SIGSEGV when a function
10909 attribute (reentrant, etc) is used on a non-function or on a
10910 function but misplaced before the parameter list.
10912 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10914 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10915 * support/Util/SDCCerr.h,
10916 * support/Util/SDCCerr.c: Added func attr misuse error msg
10918 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10920 Fixed bug #787649 by anonymous
10921 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10922 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10924 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10926 Fixed numerous bitfield problems.
10928 * src/SDCC.y: More bitfield related error checking

10937 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10939 Made the constant following the "interrupt" keyword optional. If
10940 omitted, the function will not automatically be given an entry
10941 in the interrupt vector table (similar to #pragma NOIV, but
10942 less syntacticly kludgy). The interrupt number is also now
10943 range checked. Also fixed a bug in the high order bit example

10959 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10961 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10962 be re-activated by defining REDUCE_LITERALS)
10963 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10964 unsigned, but are signed by default
10965 * src/SDCCval.c (constVal): rearranged
10966 * src/SDCCval.c (valMod): preliminary fix
10967 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11007 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11008 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11009 constants are unsigned; added recognition of "u" flag for unsigned
11010 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11011 * src/SDCCval.c (valDiv, valMod): fixed signdness

11473 added if/endif conditional macros to remove options help
11474 messages from optionsTable when a port is not configured, added
11475 support for the PIc16 port in the ports table, when executing
11476 the compiler with no port specified on command line, a default
11477 port is selected with the new macro DEFAULT_PORT which is
11478 defined in port.h, in setDefaultOptions() linkOptions is removed
11479 from initialization assignment, since now it is a set,
11480 parseCmdLine uses setParseWithComma for linkOptions, in
11481 linkEdit() linkOptions are accessed with new function indexSet()
11482 which returns the i'th item of a set variable. See SDCCset.c, in
11483 linkEdit() when calling buildCmdLine(), added linkOptions as
11484 last argument. Now users can pass arguments to gplink via the
11485 -Wl option, main() uses pic16glue() to glue up pic16 programs

11499 gpasm complaining and test the linkage with gplink, _linkCmd and
11500 _asmCmd changed to be more gplink and gpasm friendly
11501 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11502 produced an error when parsed, peep rule 12 is added to utilize
11503 movff, but it is commented out since the pCode does not support
11504 yet a command with 2 address arguments
11506 2003-05-18 <johan AT balder>
11508 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12545 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12546 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

12556 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12557 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12563 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12564 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12566 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12567 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12569 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12571 * in /sdcc/as/mcs51/ changed these files in order to create an
12572 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12573 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12574 following files to include the previous two files: aslink.dsp,
12575 Makefile.aslink, Makefile.bcc, and Makefile.in.
12577 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12578 .adb instead of .cdb
12580 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12582 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12583 value from option --iram-size.
12585 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12587 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12590 2002-09-18 <wiml AT hhhh.org>
12592 * SDCClrange.h: exposed setFromRange() and setToRange()
12593 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12594 packRegsForAccUse() (bug 542397)
12595 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12596 multiple times and emitting the fetch operations more than once
12597 added aopGetUsesAcc() function to allow binary operators to
12598 fetch their operands in the correct order; made genMinus() emit
12599 compact code for X = LITERAL - Y
12601 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12602 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12603 sprintf() in line 1267.
12605 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12606 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12609 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12610 Changes to aslink (All the changes are marked with 'JCF'):
12612 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12615 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12616 area BSEG. Also moves, if possible, the DATA area down into the internal
12617 ram so more space is available.
12619 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12622 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12623 not bytes. Function summary() which creates a memory usage summary
12624 file with extension .mem. Reports of overlaping stack and small stack
12625 size. If the space for the stack is less than 16 bytes aslink trows a
12628 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12629 the 8051. Option 'y' for memory summary output file.
12631 Changes to sdcc (All the changes are marked with 'JCF'):
12633 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12635 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12636 overlaying area for it (uses RegBankUsed[4]).
12638 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12639 bank zero as used by default. By default aslink locates the stack
12640 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12641 the creation of the .mem file. Delegates the allocation of data area
12642 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12643 the begining of the stack area to aslink.
12645 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12646 glue() in SDCCglue.c creates an area for it.
12648 2002-09-03 Borut Razem <borut.razem AT siol.net>
12649 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12650 sdcc/src/pic/glue.c:
12651 introduced atexit() handler for teporay files removal in case of
12652 errors, assertions, ...
12654 2002-08-29 Borut Razem <borut.razem AT siol.net>
12655 * sdcc/support/cpp2/auto-host_vc_in.h:
12656 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12657 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12658 Maybe there is a similar problem with BORLANDC? It should be checked!
12660 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12661 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12662 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12663 was not executed, and the compiler (cl) launched a warning:
12664 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12666 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12667 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12669 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12670 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12672 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12673 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12674 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12675 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12676 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12677 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12678 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12679 - added Release configuration in VS projects
12680 - review of compiler an linker options
12681 - VC .exe files are generated in bin_vc directory, not to interfere
12682 with binaries generated from other projects (cygwin, mingw, bcc ...)
12684 * sdcc/src/yacc.dsp: added
12686 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12687 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12688 and insert the version number definitions from .version
12690 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12692 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12693 added - genarate auto-host.h using auto-host_vc_in.h as template
12696 removed from CVS, generated automatically
12698 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12699 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12701 2002-08-11 Borut Razem <borut.razem AT siol.net>
12702 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12704 2002-08-10 Borut Razem <borut.razem AT siol.net>
12705 * src/SDCCmain.c (main):
12706 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12707 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12708 The consequence was that some temporary files were not removed.
12711 unification of code in functions tempfilename() and tempfile():
12712 function tempnam() is defined in Visual Studio 6.0 and .NET
12714 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12716 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12717 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12718 - removed compiler command line option /WX: Treats all warnings as errors
12719 - update a list of source files, included into the project
12721 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12723 changed project type to Generic Project so that can be correcly converted to VS.NET project
12725 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12727 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12729 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12731 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12732 added return 0 statements after assert() to make compiler happy
12734 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12735 added newline in the def file to keep MSC compiler satisfied
12737 * sdcc/src/z80/gen.c:
12738 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12739 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12740 - solved MSC error in function aopDump()
12742 * sdcc_vc.h: define PREFIX as "\\sdcc"
12744 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12745 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
12747 2002-06-22 Scott Dattalo <scott AT dattalo.com>
12748 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12749 - Rewrote the register banking algorithm.
12750 - Added pCode live-range analysis to registers (for now, only non-used and
12751 singly-used registers optimized away)
12753 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12755 * 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.
12757 2002-05-10 Scott Dattalo <scott AT dattalo.com>
12758 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
12760 2002-04-22 Michael Hope <michaelh AT vroom>

12770 2002-04-15 Michael Hope <michaelh AT vroom>
12772 * device/lib/z80/printf.c (sprintf): Added.
12774 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
12776 * src/z80/peeph.def: Added transpose redundent load rule.
