305 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
307 * (genCast): began a fix to optimize the casting of a bit to another
308 bit, now assigning a bitfield to another bitfield will fail, sorry,

3334 loaded with the linker search paths (-L arguments) and the libraries
3335 to be linked with the current source (-l arguments). Changes
3336 currently will affect only the pic16 port.
3337 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3338 include path the port specific paths and port specific libraries,
3339 * gplink command now contains the $3 argument,

3357 Documenting changes from previous commits.
3358 * configure.in (version 1.56),
3359 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3360 when generating output files to configure the pic16 library,
3361 but now I've commented it out, since gputils aren't installed in the
3362 SF compile farm, so library won't compile
3364 * device/lib/Makefile.in (version 1.56): initially I've added in
3365 target 'all' the prerequestive 'model-pic16' so it compiled the
3366 pic16 library, but now I've commented it out for the same reasons
3368 * added targets 'model-pic16' and 'objects-pic16' to compile the
3370 * added target 'port-specific-objects-pic16' to handle the
3371 generated libraries and copy them into the build/ directory
3372 * added target 'clean-intermediate-pic16' to clean intermediate
3373 files into pic16 directory
3374 * in target 'installdirs' added line to create directory pic16 in

3378 added lines to copy all header files to installation path,
3379 * in target 'installdirs' added line create directory for pic16
3380 headers in the installation path

3618 * support/valdiag/tests/overflow.c: added
3619 * src/SDCCast.c (decorateType),
3620 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3621 LEFT_OP (left shift)
3623 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3625 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3626 (default behaviour).
3628 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3630 A python script to validate compiler diagnostic messages. It can be
3631 used to verify that sdcc complains about bad c source code and
3632 gives a good location of the error.
3633 * support/valdiag/Makefile,
3634 * support/valdiag/valdiag.py,
3635 * support/valdiag/tests/*
3637 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3639 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3640 * src/SDCCsymt.c (newEnumType),
3642 * support/Util/SDCCerr.c,
3643 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3645 * support/regression/tests/enum.c: added test for enum values that
3646 require at least 2 bytes of storage.
3648 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3650 * src/common.h: added ifndef/define/endif macros
3651 around the header file.
3652 Bug reported from Jesus Calvino-Fraga
3654 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3656 * sdcc.spec: updated
3657 * device/include/Makefile.in: don't install CVS directories
3658 * device/lib/Makefile.in: added removal of CVS directories after install
3659 * doc/Makefile: fixed install, added local_icons
3660 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3661 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3662 * src/ds390/gen.c (genRightShift): fixed bug #870788
3663 * src/SDCCast.c (decorateType): fixed bug #870781
3665 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3667 PIC16 port related changes:
3668 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3669 added variable stackPos,
3671 * gen.c: genCall, assignResultValue: added support for
3672 pushing/retrieving function parameters to/from stack,
3673 genFunction,genEndFunction: setup stack frame for the
3675 genAddrOf: will be changed according to bug 863624
3677 * added files genutils.c and genutils.h which contain gen*
3678 debugged and optimised functions extracted from gen.c
3680 * glue.c: added variable 'externs' which holds extern symbols,
3681 pic16emitRegularMap: is modified to properly handle relocatable
3682 symbols under the new scheme,
3683 pic16createInterruptVect: is modified
3684 pic16printPublics: is modified to emit 'global' assembler directives,
3685 added pic16_printExterns to print extern symbols,
3686 pic16glue: initializes stack/frame pointer in the beginning of
3687 the assembly output. Temporary hack, will be corrected later,
3688 because gplink yet does not support stack and SDCC does not
3689 yet support a type of crt0.o object to create the final binary.
3691 * Removed many lines that contain 8051 legacy code.
3692 * The code is finally placed under a 'code' directive.
3693 * Added port specific options.
3695 * _process_pragma: simplified since now we do not need *special*
3696 include file to define SFR registers. But a separate header
3697 will be needed. This will be developed later.
3698 * _pic16_parseOptions: added, parses port specific options:
3699 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3700 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3701 --preplace-udata-with=
3703 * _pic16_setDefaultOptions: modified to initialize section names,
3704 but hack is temporarly out of order since it needs improvement.
3705 * _pic16_genAssemblerPreamble: configuration words are emitted by
3706 their address instead of their name. This part is incomplete and
3707 supports only the 18Fxx2 devices. Other devices will emit an error
3708 during assembly since they do not contain the same set of config
3710 * _pic16_genIVT: is modified,
3712 * pcode.c: added definitions for some hardware registers that are needed
3714 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3715 All PCI entries are updated. Now LFSR is supported.
3716 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3717 * added pic16_newpCodeOpLit2 to support instructions with
3718 two literal arguments
3719 * pic16_pCode2str: corrected code that emits assembler instructions
3720 with two literal operands and those that have an access bit modifier
3721 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3722 this fixes a bug which caused some labels to be lost, when an
3723 assembler directive was added, i.e. banksel,
3724 * pic16_FixRegisterBanking: improved logic that causes the insertion
3726 * InlineFunction: functions that are called once, are not any more
3727 inlined. This can be a port option in the future,
3729 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3731 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3732 hold the corresponding uninitialized symbols,
3733 * pic16_allocProcessorRegister: registers have explicit marked the
3735 * pic16_allocInternalRegister: registers are explicit marked as
3737 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3738 processing list, so bit registers were lost,
3741 * ralloc.h: added field 'accessBank' and original symbol operand
3742 in register definition,
3743 * removed the field isMapped from register definition,
3745 ** Several functions have been removed from various sources:
3746 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3747 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3748 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3749 pic16_assignRelocatableRegisters
3751 ** others have been introduced:
3752 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3753 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3755 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3757 * support/scripts/inc2h.pl: changed definition of BIT_AT
3758 to emit 'sbit at' instead of 'bit at'. This was a request.
3760 PIC16 port related preliminary changes:
3761 * gen.c: prefixed function popRegFromString with
3762 pic16_ and all references to it corrected
3763 * pcode.c: all pic16_pc_* hardware registers prefixed
3764 with underscore (_),
3765 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3766 * ralloc.c: newReg(): when register is REG_SFR then
3767 set address to rIdx,
3768 pic16_allocProcessorRegister(): marks register wasUsed=0
3769 pic16_writeUsedRegs(): added a call to assign processor
3770 registers via pic16_assignFixedRegisters
3772 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3774 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3775 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3776 variables in unused register banks. Also the SSEG is placed
3777 wherever there is enough space for it, and IDATA can be anywhere
3778 in internal RAM. For now compile using -Wl-Y[stack_size].
3779 The mem file is different for this option as well, since it
3780 makes no sense of talking about DSEG lenght.
3782 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3784 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3785 in certain cases, e.g. when ROM assignment, patch provided
3786 from Albert den Haan.
3788 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3931 * src/mcs51/peephole.def,
3932 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4027 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4029 * src/SDCCast.c (decorateType): disabled a transformation I added in
4030 revision 1.188 (access to fields of a structure at an absolute address);
4031 it breaks with bitfields, extern declarations, and gcse analysis.
4032 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4033 could be assigned through a pointer, so don't complain.
4034 * src/SDCCast.c (astErrors),
4036 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4671 * src/SDCCsymt.c (sclsFromPtr),
4673 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4674 support for standard C idiom of memory mapped variables; for
4675 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4676 to xdata int at 0x1234 tempvar = 1.
4677 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4678 provided by Akiya ISHIDA

4694 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4696 Fixed bug #621531 (const & volatile confusion in the type chain).
4697 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4698 refer to the const or volatile state of the pointer itself.

4789 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4790 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4791 fetching of the pointer
4792 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4793 copied from genNearPointerSet()
4794 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4795 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4796 If they pop r0/r1 they must be called in the opposite order than aopOp().
4797 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4798 (resp. --stack-auto), prepared for --xstack

4809 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4811 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4812 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4813 type for bits was changed. It resulted in bit variables becoming
4814 global, which is not permitted in PIC 14 assembly output.
4816 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4818 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4831 A few small changes that speed up the peephole optimizer.
4835 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4837 Try to make the peephole optimizer smarter by maintaining
4838 an association between the assembly source code and the
4839 iCodes that originated them. Put this information to use
4840 with a new peephole rule condition "notVolatile" so that
4841 the rules can be aggressive yet still safe.
4846 * src/mcs51/peeph.def
4848 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4852 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4853 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4854 if the left or right operand symbols have the accuse flag set.
4856 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4858 Changed the type of the result of the ! (NOT) operator to char;
4859 previously it returned the same type as the source. This allows
4860 us to eliminate all the genFloatNot functions (all of its target
4861 implementations were very buggy) since !float can use the same

4873 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4874 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4875 during interrupts. Ensure WSAVE is located at a shared bank address.
4876 2. Fixed page selection in some places
4877 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4878 the registers name strings.
4879 4. Fixed "signed / unsigned compare" compiler warnings.
4880 5. The PIC port manages its own allocation of the general purpose
4881 registers, but makes no attempt to reuse them. As a result when
4882 compiling it soon runs out of general purpose registers. Some
4883 additional code was added to the files pcode.c and device.c to walk
4884 through the function call tree and rename the registers so that they
4894 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4895 genPlus() & genMinus() when the result is the same as left or right

4901 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4903 Made bitfield a distinct type from bit so that bitfields
4904 convert as per ANSI C and bits retain their traditional
4905 boolean style behaviour. Implemented bitfield support in
4913 * src/ds390/gen.c: bit v bitfield split
4914 * src/z80/gen.c: New support for bitfields
4915 * support/regression/tests/bitfields.c: reenabled z80,
4918 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4920 Rules 246.x, 247.x relate to bitfields, the others speed up
4921 access to xdata mapped I/O devices.
4923 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4925 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4927 Cleaned up genPackBits and genUnpackBits and added two helper
4928 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4929 for literal assignments in genPackBits (thanks to Frieder for
4935 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4937 Fixed bug #748310 (pointer to function type mishandled when the
4938 function name is omitted). Also fixed a SIGSEGV when a function
4939 attribute (reentrant, etc) is used on a non-function or on a
4940 function but misplaced before the parameter list.
4942 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4944 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4945 * support/Util/SDCCerr.h,
4946 * support/Util/SDCCerr.c: Added func attr misuse error msg

4967 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4969 Made the constant following the "interrupt" keyword optional. If
4970 omitted, the function will not automatically be given an entry
4971 in the interrupt vector table (similar to #pragma NOIV, but
4972 less syntacticly kludgy). The interrupt number is also now
4973 range checked. Also fixed a bug in the high order bit example

4987 * src/SDCCicode.c (operandOperation): rewritten some ops
4988 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4989 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4991 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4992 be re-activated by defining REDUCE_LITERALS)
4993 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4994 unsigned, but are signed by default
4995 * src/SDCCval.c (constVal): rearranged
4996 * src/SDCCval.c (valMod): preliminary fix
4997 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5039 constants are unsigned; added recognition of "u" flag for unsigned
5040 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5041 * src/SDCCval.c (valDiv, valMod): fixed signdness
5042 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5043 signedness of modulo, left and right shift

5503 added if/endif conditional macros to remove options help
5504 messages from optionsTable when a port is not configured, added
5505 support for the PIc16 port in the ports table, when executing
5506 the compiler with no port specified on command line, a default
5507 port is selected with the new macro DEFAULT_PORT which is
5508 defined in port.h, in setDefaultOptions() linkOptions is removed
5509 from initialization assignment, since now it is a set,
5510 parseCmdLine uses setParseWithComma for linkOptions, in
5511 linkEdit() linkOptions are accessed with new function indexSet()
5512 which returns the i'th item of a set variable. See SDCCset.c, in
5513 linkEdit() when calling buildCmdLine(), added linkOptions as
5514 last argument. Now users can pass arguments to gplink via the
5515 -Wl option, main() uses pic16glue() to glue up pic16 programs

5529 gpasm complaining and test the linkage with gplink, _linkCmd and
5530 _asmCmd changed to be more gplink and gpasm friendly
5531 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5532 produced an error when parsed, peep rule 12 is added to utilize
5533 movff, but it is commented out since the pCode does not support
5534 yet a command with 2 address arguments
5536 2003-05-18 <johan AT balder>
5538 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5565 2003-05-11 Borut Razem <borut.razem AT siol.net>
5567 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6551 * support/regression/fwk/lib/timeout.c: fix usage string
6553 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
6554 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6556 2003-01-07 <johan AT balder>
6558 * src/SDCCast.c (decorateType): fixed bug #600035
6560 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6561 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6571 2003-01-06 <johan AT balder>
6573 * src/SDCCicode.c: fixed array add
6575 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6576 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6577 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6579 2003-01-04 <johan AT balder>
6581 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6583 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6584 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6586 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6587 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6588 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6590 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6591 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6593 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6594 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6596 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6597 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6599 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6601 * in \sdcc\as\mcs51\ changed these files in order to create an
6602 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6603 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6604 following files to include the previous two files: aslink.dsp,
6605 Makefile.aslink, Makefile.bcc, and Makefile.in.
6607 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6608 .adb instead of .cdb
6610 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6612 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6613 value from option --iram-size.
6615 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6617 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6620 2002-09-18 <wiml AT hhhh.org>
6622 * SDCClrange.h: exposed setFromRange() and setToRange()
6623 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6624 packRegsForAccUse() (bug 542397)
6625 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6626 multiple times and emitting the fetch operations more than once
6627 added aopGetUsesAcc() function to allow binary operators to
6628 fetch their operands in the correct order; made genMinus() emit
6629 compact code for X = LITERAL - Y
6631 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6632 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6633 sprintf() in line 1267.
6635 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6636 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6639 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6640 Changes to aslink (All the changes are marked with 'JCF'):
6642 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6645 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6646 area BSEG. Also moves, if possible, the DATA area down into the internal
6647 ram so more space is available.
6649 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6652 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6653 not bytes. Function summary() which creates a memory usage summary
6654 file with extension .mem. Reports of overlaping stack and small stack
6655 size. If the space for the stack is less than 16 bytes aslink trows a
6658 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6659 the 8051. Option 'y' for memory summary output file.
6661 Changes to sdcc (All the changes are marked with 'JCF'):
6663 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6665 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6666 overlaying area for it (uses RegBankUsed[4]).
6668 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6669 bank zero as used by default. By default aslink locates the stack
6670 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6671 the creation of the .mem file. Delegates the allocation of data area
6672 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6673 the begining of the stack area to aslink.
6675 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6676 glue() in SDCCglue.c creates an area for it.
6678 2002-09-03 Borut Razem <borut.razem AT siol.net>
6679 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6680 sdcc/src/pic/glue.c:
6681 introduced atexit() handler for teporay files removal in case of
6682 errors, assertions, ...
6684 2002-08-29 Borut Razem <borut.razem AT siol.net>
6685 * sdcc/support/cpp2/auto-host_vc_in.h:
6686 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6687 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6688 Maybe there is a similar problem with BORLANDC? It should be checked!
6690 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6691 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6692 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6693 was not executed, and the compiler (cl) launched a warning:
6694 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6696 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6697 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6699 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6700 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6702 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6703 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6704 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6705 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6706 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6707 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6708 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6709 - added Release configuration in VS projects
6710 - review of compiler an linker options
6711 - VC .exe files are generated in bin_vc directory, not to interfere
6712 with binaries generated from other projects (cygwin, mingw, bcc ...)
6714 * sdcc/src/yacc.dsp: added
6716 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6717 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6718 and insert the version number definitions from .version
6720 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6722 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6723 added - genarate auto-host.h using auto-host_vc_in.h as template
6726 removed from CVS, generated automatically
6728 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6729 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6731 2002-08-11 Borut Razem <borut.razem AT siol.net>
6732 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6734 2002-08-10 Borut Razem <borut.razem AT siol.net>
6735 * src/SDCCmain.c (main):
6736 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6737 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6738 The consequence was that some temporary files were not removed.
6741 unification of code in functions tempfilename() and tempfile():
6742 function tempnam() is defined in Visual Studio 6.0 and .NET
6744 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6746 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6747 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6748 - removed compiler command line option /WX: Treats all warnings as errors
6749 - update a list of source files, included into the project
6751 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6752 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6753 changed project type to Generic Project so that can be correcly converted to VS.NET project
6755 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6757 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6759 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6761 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6762 added return 0 statements after assert() to make compiler happy
6764 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6765 added newline in the def file to keep MSC compiler satisfied
6767 * sdcc/src/z80/gen.c:
6768 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6769 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6770 - solved MSC error in function aopDump()
6772 * sdcc_vc.h: define PREFIX as "\\sdcc"
6774 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6775 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6777 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6778 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6779 - Rewrote the register banking algorithm.
6780 - Added pCode live-range analysis to registers (for now, only non-used and
6781 singly-used registers optimized away)
6783 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6785 * 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.

6810 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6812 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6814 2002-03-28 Johan Knol <johan AT balder>
6816 * src/SDCCval.c: fixed bug #532436
6818 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6820 Added "char *Processor" field to the port structure.
6823 Added -p option. Allows port dependent processor to be specified.
6826 Initialized the new field char *Processor field to NULL in all ports
6829 Compiler generated registers for interrupt context saving
6830 were not getting allocated.
6832 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6835 Fixed left shift. Will promote the left side of a left shift
6836 if a) left shifting more than size of operand or b) when assigned
6837 to something size > size of left side
6839 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6841 tons of changes. Register allocation has been
6842 rewritten. Added customization for the various PICs. Flow
6843 analysis is restructured. ...
6849 Added. device.c is a PIC port hack to accomodate variations
6852 2002-03-13 Michael Hope <michaelh AT vroom>
6854 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6856 2002-03-04 johanknol <johanknol AT manik>
6858 * /src/SDCCval.c: fixed
6860 const unsigned char arr[][2] = { { 0, 1 } };
6861 t18.c:1: error: Initializer element is not constant
6863 2002-03-04 bela <bela AT manik>
6865 * /device/include/mcs51reg.h:
6866 ds89c420 register definition update
6868 2002-03-03 <johan AT FRIJA>

6947 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6949 * sdcc/src/SDCCloop.c:
6950 Previous fix was not good. basic blocks that have "break" or "return" are
6951 not really partof a loop , but live ranges used in these blocks should
6952 be live thru the entire loop, so set partOfLoop but don't add them to
6955 2002-02-21 <johan AT FRIJA>
6957 * src/SDCCcse.c: fixed bug #514308
6959 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6962 Fixed BUG #519583. If a conditional block ended in a return/break
6963 statement inside a loop, it was not being considered part of the loop.
6965 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6967 2002-02-10 Karl Bongers <karl AT turbobit.com>
6970 Fixed up SDCDB debugger somewhat. Updated debugger/README
6971 with lots of comments and notes.
6973 * device/examples/test2.c:
6974 Fix bug, "red" variable not being initialized(compiler complained).
6976 * device/examples/Makefile, examples/test3.c:
6977 Add Makefile in device/examples folder, compiles test3.c
6978 for use as a multiple module SDCDB test case.
6980 * sim/ucsim/cmd.src/cmdset.cc:
6981 Took out debug printfs in ucsim "next" command.
6984 Karl and Johan start ucsim XA support. Most dissassembly working,
6985 about 75% emulation done(plenty of work remaining).
6987 * sim/ucsim/z80.src:
6988 Add Z80 support to ucsim, add test-ucz80 regression test,
6989 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6990 Notice z80 compiler fails on examples/test3.c/crc code.
6992 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
6994 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
6995 Added support for --parms-in-bank1
6997 * src/ds390/peeph.def:

7002 from a memory mapped port
7003 2) added __builtin_memcmp
7004 3) added __builtin_swapw swap bytes of a short
7006 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
7007 1) handle multiple send & receives from register bank1
7008 2) ralloc can now allocate DPTR1 to some liveRanges
7010 * src/SDCCsymt.c, src/SDCCsymt.h:
7011 changes to handle multiple sends & receives
7014 added some pointer arithmetic optimization
7017 added some pointer arithmetic optimizations but not stable yet so not
7018 called from anywhere (will get this working shortly)
7020 * src/SDCCopt.c: fixed for multiple sends & receives
7023 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
7024 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
7025 set preprocessor defines (depending on options)
7027 * src/SDCCicode.c, src/SDCCicode.h:
7028 changes made to handle multiple sends & receives
7031 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
