294 Adding support for replacing ljmps with sjmps in jumptables
295 generated for switch statements. For now you need to set the
296 environment variable SDCC_SJMP_JUMPTABLE to enable this.
297 Now 4 algorithms for mcs51 jumptable generation are used:
298 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

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

3381 loaded with the linker search paths (-L arguments) and the libraries
3382 to be linked with the current source (-l arguments). Changes
3383 currently will affect only the pic16 port.
3384 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3385 include path the port specific paths and port specific libraries,
3386 * gplink command now contains the $3 argument,
3387 * src/pic16/device.h,
3388 * src/pic16/device.c,: structure PIC_device is made public and
3389 renamed to PIC16_device, the same for variable Pics which is renamed

3404 Documenting changes from previous commits.
3405 * configure.in (version 1.56),
3406 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3407 when generating output files to configure the pic16 library,
3408 but now I've commented it out, since gputils aren't installed in the
3409 SF compile farm, so library won't compile
3411 * device/lib/Makefile.in (version 1.56): initially I've added in
3412 target 'all' the prerequestive 'model-pic16' so it compiled the
3413 pic16 library, but now I've commented it out for the same reasons
3415 * added targets 'model-pic16' and 'objects-pic16' to compile the
3417 * added target 'port-specific-objects-pic16' to handle the
3418 generated libraries and copy them into the build/ directory
3419 * added target 'clean-intermediate-pic16' to clean intermediate
3420 files into pic16 directory
3421 * in target 'installdirs' added line to create directory pic16 in

3609 structure to inform whether to create a .lnk file or not,
3617 * src/z80/main.c: changed appropriately to configure
3618 needLinkerScript flag
3620 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3621 * src/pic/glue.c: added variable udata_section_name to
3622 override default uninitialized data segment definition for

3632 arguments via -W option
3633 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3634 object file from '.rel' to '.o' in port->linker structure,
3635 changed size of fptr from 2 to 3 in port structure
3637 2004-01-07 Borut Razem <borut.razem AT siol.net>
3639 * support/scripts/sdcc.nsi: update PATH
3640 * support/scripts/sdcc.ico: craeted

3653 include information about variables allocated to the overlay
3656 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3658 * as/mcs51/lkmain.c: Help about -Y option
3659 * as/mcs51/lkarea.c: Fixed gcc warnings
3661 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

3665 * support/valdiag/tests/overflow.c: added
3666 * src/SDCCast.c (decorateType),
3667 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3668 LEFT_OP (left shift)
3670 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3672 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3673 (default behaviour).
3675 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3677 A python script to validate compiler diagnostic messages. It can be
3678 used to verify that sdcc complains about bad c source code and
3679 gives a good location of the error.
3680 * support/valdiag/Makefile,
3681 * support/valdiag/valdiag.py,
3682 * support/valdiag/tests/*
3684 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3686 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3695 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3697 * src/common.h: added ifndef/define/endif macros
3698 around the header file.
3699 Bug reported from Jesus Calvino-Fraga
3701 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3703 * sdcc.spec: updated
3704 * device/include/Makefile.in: don't install CVS directories
3705 * device/lib/Makefile.in: added removal of CVS directories after install
3706 * doc/Makefile: fixed install, added local_icons
3707 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3708 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3709 * src/ds390/gen.c (genRightShift): fixed bug #870788
3710 * src/SDCCast.c (decorateType): fixed bug #870781
3712 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3714 PIC16 port related changes:
3715 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3716 added variable stackPos,
3718 * gen.c: genCall, assignResultValue: added support for
3719 pushing/retrieving function parameters to/from stack,
3720 genFunction,genEndFunction: setup stack frame for the
3722 genAddrOf: will be changed according to bug 863624
3724 * added files genutils.c and genutils.h which contain gen*
3725 debugged and optimised functions extracted from gen.c
3727 * glue.c: added variable 'externs' which holds extern symbols,
3728 pic16emitRegularMap: is modified to properly handle relocatable
3729 symbols under the new scheme,
3730 pic16createInterruptVect: is modified
3731 pic16printPublics: is modified to emit 'global' assembler directives,
3732 added pic16_printExterns to print extern symbols,
3733 pic16glue: initializes stack/frame pointer in the beginning of
3734 the assembly output. Temporary hack, will be corrected later,
3735 because gplink yet does not support stack and SDCC does not
3736 yet support a type of crt0.o object to create the final binary.
3738 * Removed many lines that contain 8051 legacy code.
3739 * The code is finally placed under a 'code' directive.
3740 * Added port specific options.
3742 * _process_pragma: simplified since now we do not need *special*
3743 include file to define SFR registers. But a separate header
3744 will be needed. This will be developed later.
3745 * _pic16_parseOptions: added, parses port specific options:
3746 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3747 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3748 --preplace-udata-with=
3750 * _pic16_setDefaultOptions: modified to initialize section names,
3751 but hack is temporarly out of order since it needs improvement.
3752 * _pic16_genAssemblerPreamble: configuration words are emitted by
3753 their address instead of their name. This part is incomplete and
3754 supports only the 18Fxx2 devices. Other devices will emit an error
3755 during assembly since they do not contain the same set of config
3757 * _pic16_genIVT: is modified,
3759 * pcode.c: added definitions for some hardware registers that are needed
3761 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3762 All PCI entries are updated. Now LFSR is supported.
3763 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3764 * added pic16_newpCodeOpLit2 to support instructions with
3765 two literal arguments
3766 * pic16_pCode2str: corrected code that emits assembler instructions
3767 with two literal operands and those that have an access bit modifier
3768 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3769 this fixes a bug which caused some labels to be lost, when an
3770 assembler directive was added, i.e. banksel,
3771 * pic16_FixRegisterBanking: improved logic that causes the insertion
3773 * InlineFunction: functions that are called once, are not any more
3774 inlined. This can be a port option in the future,
3776 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3778 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3779 hold the corresponding uninitialized symbols,
3780 * pic16_allocProcessorRegister: registers have explicit marked the
3782 * pic16_allocInternalRegister: registers are explicit marked as
3784 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3785 processing list, so bit registers were lost,
3788 * ralloc.h: added field 'accessBank' and original symbol operand
3789 in register definition,
3790 * removed the field isMapped from register definition,
3792 ** Several functions have been removed from various sources:
3793 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3794 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3795 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3796 pic16_assignRelocatableRegisters
3798 ** others have been introduced:
3799 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3800 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3802 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3804 * support/scripts/inc2h.pl: changed definition of BIT_AT
3805 to emit 'sbit at' instead of 'bit at'. This was a request.
3807 PIC16 port related preliminary changes:
3808 * gen.c: prefixed function popRegFromString with
3809 pic16_ and all references to it corrected
3810 * pcode.c: all pic16_pc_* hardware registers prefixed
3811 with underscore (_),
3812 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3813 * ralloc.c: newReg(): when register is REG_SFR then
3814 set address to rIdx,
3815 pic16_allocProcessorRegister(): marks register wasUsed=0
3816 pic16_writeUsedRegs(): added a call to assign processor
3817 registers via pic16_assignFixedRegisters
3819 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3821 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3822 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3823 variables in unused register banks. Also the SSEG is placed
3824 wherever there is enough space for it, and IDATA can be anywhere
3825 in internal RAM. For now compile using -Wl-Y[stack_size].
3826 The mem file is different for this option as well, since it
3827 makes no sense of talking about DSEG lenght.
3829 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3831 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3832 in certain cases, e.g. when ROM assignment, patch provided
3833 from Albert den Haan.

4074 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4076 * src/SDCCast.c (decorateType): disabled a transformation I added in
4077 revision 1.188 (access to fields of a structure at an absolute address);
4078 it breaks with bitfields, extern declarations, and gcse analysis.
4079 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4080 could be assigned through a pointer, so don't complain.

4720 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4721 support for standard C idiom of memory mapped variables; for
4722 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4723 to xdata int at 0x1234 tempvar = 1.
4724 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

4741 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4743 Fixed bug #621531 (const & volatile confusion in the type chain).
4744 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4837 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4838 fetching of the pointer
4839 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4840 copied from genNearPointerSet()
4841 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4842 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4843 If they pop r0/r1 they must be called in the opposite order than aopOp().

4858 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4859 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4860 type for bits was changed. It resulted in bit variables becoming
4861 global, which is not permitted in PIC 14 assembly output.
4863 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4878 A few small changes that speed up the peephole optimizer.
4882 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4884 Try to make the peephole optimizer smarter by maintaining
4885 an association between the assembly source code and the
4886 iCodes that originated them. Put this information to use
4887 with a new peephole rule condition "notVolatile" so that
4888 the rules can be aggressive yet still safe.
4893 * src/mcs51/peeph.def
4895 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4899 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4900 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4901 if the left or right operand symbols have the accuse flag set.
4903 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4905 Changed the type of the result of the ! (NOT) operator to char;
4906 previously it returned the same type as the source. This allows
4907 us to eliminate all the genFloatNot functions (all of its target
4908 implementations were very buggy) since !float can use the same
4911 * src/SDCCicode.c (ast2iCode): ! returns char

4920 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4921 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4922 during interrupts. Ensure WSAVE is located at a shared bank address.
4923 2. Fixed page selection in some places
4924 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4925 the registers name strings.
4926 4. Fixed "signed / unsigned compare" compiler warnings.
4927 5. The PIC port manages its own allocation of the general purpose
4928 registers, but makes no attempt to reuse them. As a result when
4929 compiling it soon runs out of general purpose registers. Some
4930 additional code was added to the files pcode.c and device.c to walk
4931 through the function call tree and rename the registers so that they
4941 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4942 genPlus() & genMinus() when the result is the same as left or right

4948 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4950 Made bitfield a distinct type from bit so that bitfields
4951 convert as per ANSI C and bits retain their traditional
4952 boolean style behaviour. Implemented bitfield support in
4960 * src/ds390/gen.c: bit v bitfield split
4961 * src/z80/gen.c: New support for bitfields
4962 * support/regression/tests/bitfields.c: reenabled z80,
4965 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4967 Rules 246.x, 247.x relate to bitfields, the others speed up
4968 access to xdata mapped I/O devices.
4970 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4972 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4974 Cleaned up genPackBits and genUnpackBits and added two helper
4975 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4976 for literal assignments in genPackBits (thanks to Frieder for
4982 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4984 Fixed bug #748310 (pointer to function type mishandled when the
4985 function name is omitted). Also fixed a SIGSEGV when a function
4986 attribute (reentrant, etc) is used on a non-function or on a
4987 function but misplaced before the parameter list.
4989 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4991 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4992 * support/Util/SDCCerr.h,

5014 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5016 Made the constant following the "interrupt" keyword optional. If
5017 omitted, the function will not automatically be given an entry
5018 in the interrupt vector table (similar to #pragma NOIV, but
5019 less syntacticly kludgy). The interrupt number is also now
5020 range checked. Also fixed a bug in the high order bit example

5086 constants are unsigned; added recognition of "u" flag for unsigned
5087 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5088 * src/SDCCval.c (valDiv, valMod): fixed signdness
5089 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

5550 added if/endif conditional macros to remove options help
5551 messages from optionsTable when a port is not configured, added
5552 support for the PIc16 port in the ports table, when executing
5553 the compiler with no port specified on command line, a default
5554 port is selected with the new macro DEFAULT_PORT which is
5555 defined in port.h, in setDefaultOptions() linkOptions is removed
5556 from initialization assignment, since now it is a set,
5557 parseCmdLine uses setParseWithComma for linkOptions, in
5558 linkEdit() linkOptions are accessed with new function indexSet()
5559 which returns the i'th item of a set variable. See SDCCset.c, in
5560 linkEdit() when calling buildCmdLine(), added linkOptions as
5561 last argument. Now users can pass arguments to gplink via the
5562 -Wl option, main() uses pic16glue() to glue up pic16 programs

5576 gpasm complaining and test the linkage with gplink, _linkCmd and
5577 _asmCmd changed to be more gplink and gpasm friendly
5578 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5579 produced an error when parsed, peep rule 12 is added to utilize
5580 movff, but it is commented out since the pCode does not support
5581 yet a command with 2 address arguments
5583 2003-05-18 <johan AT balder>
5585 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6603 2003-01-07 <johan AT balder>
6605 * src/SDCCast.c (decorateType): fixed bug #600035
6607 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6618 2003-01-06 <johan AT balder>
6620 * src/SDCCicode.c: fixed array add
6622 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6623 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6624 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6626 2003-01-04 <johan AT balder>
6628 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6630 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6631 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6633 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6634 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6640 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6641 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6643 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6644 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6646 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6648 * in \sdcc\as\mcs51\ changed these files in order to create an
6649 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6650 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6651 following files to include the previous two files: aslink.dsp,
6652 Makefile.aslink, Makefile.bcc, and Makefile.in.
6654 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6655 .adb instead of .cdb
6657 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6659 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6660 value from option --iram-size.
6662 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6664 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6667 2002-09-18 <wiml AT hhhh.org>
6669 * SDCClrange.h: exposed setFromRange() and setToRange()
6670 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6671 packRegsForAccUse() (bug 542397)
6672 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6673 multiple times and emitting the fetch operations more than once
6674 added aopGetUsesAcc() function to allow binary operators to
6675 fetch their operands in the correct order; made genMinus() emit
6676 compact code for X = LITERAL - Y
6678 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6679 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6680 sprintf() in line 1267.
6682 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6683 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6686 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6687 Changes to aslink (All the changes are marked with 'JCF'):
6689 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6692 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6693 area BSEG. Also moves, if possible, the DATA area down into the internal
6694 ram so more space is available.
6696 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6699 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6700 not bytes. Function summary() which creates a memory usage summary
6701 file with extension .mem. Reports of overlaping stack and small stack
6702 size. If the space for the stack is less than 16 bytes aslink trows a
6705 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6706 the 8051. Option 'y' for memory summary output file.
6708 Changes to sdcc (All the changes are marked with 'JCF'):
6710 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6712 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6713 overlaying area for it (uses RegBankUsed[4]).
6715 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6716 bank zero as used by default. By default aslink locates the stack
6717 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6718 the creation of the .mem file. Delegates the allocation of data area
6719 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6720 the begining of the stack area to aslink.
6722 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6723 glue() in SDCCglue.c creates an area for it.
6725 2002-09-03 Borut Razem <borut.razem AT siol.net>
6726 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6727 sdcc/src/pic/glue.c:
6728 introduced atexit() handler for teporay files removal in case of
6729 errors, assertions, ...
6731 2002-08-29 Borut Razem <borut.razem AT siol.net>
6732 * sdcc/support/cpp2/auto-host_vc_in.h:
6733 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6734 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6735 Maybe there is a similar problem with BORLANDC? It should be checked!
6737 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6738 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6739 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6740 was not executed, and the compiler (cl) launched a warning:
6741 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6743 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6744 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6746 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6747 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6749 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6750 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6751 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6752 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6753 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6754 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6755 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6756 - added Release configuration in VS projects
6757 - review of compiler an linker options
6758 - VC .exe files are generated in bin_vc directory, not to interfere
6759 with binaries generated from other projects (cygwin, mingw, bcc ...)
6761 * sdcc/src/yacc.dsp: added
6763 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6764 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6765 and insert the version number definitions from .version
6767 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6769 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6770 added - genarate auto-host.h using auto-host_vc_in.h as template
6773 removed from CVS, generated automatically
6775 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6776 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6778 2002-08-11 Borut Razem <borut.razem AT siol.net>
6779 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6781 2002-08-10 Borut Razem <borut.razem AT siol.net>
6782 * src/SDCCmain.c (main):
6783 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6784 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6785 The consequence was that some temporary files were not removed.
6788 unification of code in functions tempfilename() and tempfile():
6789 function tempnam() is defined in Visual Studio 6.0 and .NET
6791 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6793 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6794 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6795 - removed compiler command line option /WX: Treats all warnings as errors
6796 - update a list of source files, included into the project
6798 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6799 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6800 changed project type to Generic Project so that can be correcly converted to VS.NET project
6802 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6804 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6806 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6808 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6809 added return 0 statements after assert() to make compiler happy
6811 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6812 added newline in the def file to keep MSC compiler satisfied
6814 * sdcc/src/z80/gen.c:
6815 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6816 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6817 - solved MSC error in function aopDump()
6819 * sdcc_vc.h: define PREFIX as "\\sdcc"
6821 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6822 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6825 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6826 - Rewrote the register banking algorithm.
6827 - Added pCode live-range analysis to registers (for now, only non-used and
6828 singly-used registers optimized away)
6830 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6832 * 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.

6859 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6861 2002-03-28 Johan Knol <johan AT balder>
6863 * src/SDCCval.c: fixed bug #532436
6865 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6867 Added "char *Processor" field to the port structure.
6870 Added -p option. Allows port dependent processor to be specified.
6873 Initialized the new field char *Processor field to NULL in all ports
6876 Compiler generated registers for interrupt context saving
6877 were not getting allocated.
6879 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6882 Fixed left shift. Will promote the left side of a left shift
6883 if a) left shifting more than size of operand or b) when assigned
6884 to something size > size of left side
6886 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6888 tons of changes. Register allocation has been
6889 rewritten. Added customization for the various PICs. Flow
6890 analysis is restructured. ...
6896 Added. device.c is a PIC port hack to accomodate variations
6899 2002-03-13 Michael Hope <michaelh AT vroom>
6901 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6903 2002-03-04 johanknol <johanknol AT manik>
6905 * /src/SDCCval.c: fixed
6907 const unsigned char arr[][2] = { { 0, 1 } };
6908 t18.c:1: error: Initializer element is not constant
6910 2002-03-04 bela <bela AT manik>
6912 * /device/include/mcs51reg.h:
6913 ds89c420 register definition update

6994 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6996 * sdcc/src/SDCCloop.c:
6997 Previous fix was not good. basic blocks that have "break" or "return" are
6998 not really partof a loop , but live ranges used in these blocks should
6999 be live thru the entire loop, so set partOfLoop but don't add them to
7002 2002-02-21 <johan AT FRIJA>
7004 * src/SDCCcse.c: fixed bug #514308
7006 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7009 Fixed BUG #519583. If a conditional block ended in a return/break
7010 statement inside a loop, it was not being considered part of the loop.
7012 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7014 2002-02-10 Karl Bongers <karl AT turbobit.com>
7017 Fixed up SDCDB debugger somewhat. Updated debugger/README
7018 with lots of comments and notes.
7020 * device/examples/test2.c:
7021 Fix bug, "red" variable not being initialized(compiler complained).
