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

319 functions, ctype functions and macros and some functions of the
320 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
321 be extensively tested in the future. Standard disclaimer here.
322 Library is not automatically build yet. But one can build it by

336 special compare&skip instructions. Initial tests fail some times
337 with variables grater than 1 byte in size, so new code is disabled,
338 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
340 * (genCast): began a fix to optimize the casting of a bit to another
341 bit, now assigning a bitfield to another bitfield will fail, sorry,

3367 loaded with the linker search paths (-L arguments) and the libraries
3368 to be linked with the current source (-l arguments). Changes
3369 currently will affect only the pic16 port.
3370 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3371 include path the port specific paths and port specific libraries,
3372 * gplink command now contains the $3 argument,
3373 * src/pic16/device.h,
3374 * src/pic16/device.c,: structure PIC_device is made public and
3375 renamed to PIC16_device, the same for variable Pics which is renamed

3390 Documenting changes from previous commits.
3391 * configure.in (version 1.56),
3392 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3393 when generating output files to configure the pic16 library,
3394 but now I've commented it out, since gputils aren't installed in the
3395 SF compile farm, so library won't compile
3397 * device/lib/Makefile.in (version 1.56): initially I've added in
3398 target 'all' the prerequestive 'model-pic16' so it compiled the
3399 pic16 library, but now I've commented it out for the same reasons
3401 * added targets 'model-pic16' and 'objects-pic16' to compile the
3403 * added target 'port-specific-objects-pic16' to handle the
3404 generated libraries and copy them into the build/ directory
3405 * added target 'clean-intermediate-pic16' to clean intermediate
3406 files into pic16 directory
3407 * in target 'installdirs' added line to create directory pic16 in

3411 added lines to copy all header files to installation path,
3412 * in target 'installdirs' added line create directory for pic16
3413 headers in the installation path

3652 * src/SDCCast.c (decorateType),
3653 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3654 LEFT_OP (left shift)
3656 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3658 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3659 (default behaviour).
3661 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3663 A python script to validate compiler diagnostic messages. It can be
3664 used to verify that sdcc complains about bad c source code and
3665 gives a good location of the error.
3666 * support/valdiag/Makefile,
3667 * support/valdiag/valdiag.py,
3668 * support/valdiag/tests/*
3670 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3683 * src/common.h: added ifndef/define/endif macros
3684 around the header file.
3685 Bug reported from Jesus Calvino-Fraga
3687 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3689 * sdcc.spec: updated
3690 * device/include/Makefile.in: don't install CVS directories
3691 * device/lib/Makefile.in: added removal of CVS directories after install
3692 * doc/Makefile: fixed install, added local_icons
3693 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3694 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3695 * src/ds390/gen.c (genRightShift): fixed bug #870788

3698 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3700 PIC16 port related changes:
3701 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3702 added variable stackPos,
3704 * gen.c: genCall, assignResultValue: added support for
3705 pushing/retrieving function parameters to/from stack,
3706 genFunction,genEndFunction: setup stack frame for the
3708 genAddrOf: will be changed according to bug 863624
3710 * added files genutils.c and genutils.h which contain gen*
3711 debugged and optimised functions extracted from gen.c
3713 * glue.c: added variable 'externs' which holds extern symbols,
3714 pic16emitRegularMap: is modified to properly handle relocatable
3715 symbols under the new scheme,
3716 pic16createInterruptVect: is modified
3717 pic16printPublics: is modified to emit 'global' assembler directives,
3718 added pic16_printExterns to print extern symbols,
3719 pic16glue: initializes stack/frame pointer in the beginning of
3720 the assembly output. Temporary hack, will be corrected later,
3721 because gplink yet does not support stack and SDCC does not
3722 yet support a type of crt0.o object to create the final binary.
3724 * Removed many lines that contain 8051 legacy code.
3725 * The code is finally placed under a 'code' directive.
3726 * Added port specific options.
3728 * _process_pragma: simplified since now we do not need *special*
3729 include file to define SFR registers. But a separate header
3730 will be needed. This will be developed later.
3731 * _pic16_parseOptions: added, parses port specific options:
3732 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3733 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3734 --preplace-udata-with=
3736 * _pic16_setDefaultOptions: modified to initialize section names,
3737 but hack is temporarly out of order since it needs improvement.
3738 * _pic16_genAssemblerPreamble: configuration words are emitted by
3739 their address instead of their name. This part is incomplete and
3740 supports only the 18Fxx2 devices. Other devices will emit an error
3741 during assembly since they do not contain the same set of config
3743 * _pic16_genIVT: is modified,
3745 * pcode.c: added definitions for some hardware registers that are needed
3747 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3748 All PCI entries are updated. Now LFSR is supported.
3749 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3750 * added pic16_newpCodeOpLit2 to support instructions with
3751 two literal arguments
3752 * pic16_pCode2str: corrected code that emits assembler instructions
3753 with two literal operands and those that have an access bit modifier
3754 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3755 this fixes a bug which caused some labels to be lost, when an
3756 assembler directive was added, i.e. banksel,
3757 * pic16_FixRegisterBanking: improved logic that causes the insertion
3759 * InlineFunction: functions that are called once, are not any more
3760 inlined. This can be a port option in the future,
3762 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3764 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3765 hold the corresponding uninitialized symbols,
3766 * pic16_allocProcessorRegister: registers have explicit marked the
3768 * pic16_allocInternalRegister: registers are explicit marked as
3770 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3771 processing list, so bit registers were lost,
3774 * ralloc.h: added field 'accessBank' and original symbol operand
3775 in register definition,
3776 * removed the field isMapped from register definition,
3778 ** Several functions have been removed from various sources:
3779 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3780 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3781 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3782 pic16_assignRelocatableRegisters
3784 ** others have been introduced:
3785 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3786 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3788 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3790 * support/scripts/inc2h.pl: changed definition of BIT_AT
3791 to emit 'sbit at' instead of 'bit at'. This was a request.
3793 PIC16 port related preliminary changes:
3794 * gen.c: prefixed function popRegFromString with
3795 pic16_ and all references to it corrected
3796 * pcode.c: all pic16_pc_* hardware registers prefixed
3797 with underscore (_),
3798 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3799 * ralloc.c: newReg(): when register is REG_SFR then
3800 set address to rIdx,
3801 pic16_allocProcessorRegister(): marks register wasUsed=0
3802 pic16_writeUsedRegs(): added a call to assign processor
3803 registers via pic16_assignFixedRegisters
3805 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3807 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3808 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3809 variables in unused register banks. Also the SSEG is placed
3810 wherever there is enough space for it, and IDATA can be anywhere
3811 in internal RAM. For now compile using -Wl-Y[stack_size].
3812 The mem file is different for this option as well, since it
3813 makes no sense of talking about DSEG lenght.
3815 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3817 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3818 in certain cases, e.g. when ROM assignment, patch provided
3819 from Albert den Haan.
3821 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4060 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4062 * src/SDCCast.c (decorateType): disabled a transformation I added in
4063 revision 1.188 (access to fields of a structure at an absolute address);
4064 it breaks with bitfields, extern declarations, and gcse analysis.
4065 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4066 could be assigned through a pointer, so don't complain.
4067 * src/SDCCast.c (astErrors),
4069 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4071 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

4822 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4823 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4824 fetching of the pointer
4825 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4826 copied from genNearPointerSet()
4827 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4828 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4844 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4845 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4846 type for bits was changed. It resulted in bit variables becoming
4847 global, which is not permitted in PIC 14 assembly output.
4849 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4864 A few small changes that speed up the peephole optimizer.
4868 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4870 Try to make the peephole optimizer smarter by maintaining
4871 an association between the assembly source code and the
4872 iCodes that originated them. Put this information to use
4873 with a new peephole rule condition "notVolatile" so that
4874 the rules can be aggressive yet still safe.
4879 * src/mcs51/peeph.def
4881 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4885 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4886 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4887 if the left or right operand symbols have the accuse flag set.
4889 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4891 Changed the type of the result of the ! (NOT) operator to char;
4892 previously it returned the same type as the source. This allows
4893 us to eliminate all the genFloatNot functions (all of its target
4894 implementations were very buggy) since !float can use the same

4907 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4908 during interrupts. Ensure WSAVE is located at a shared bank address.
4909 2. Fixed page selection in some places
4910 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4911 the registers name strings.
4912 4. Fixed "signed / unsigned compare" compiler warnings.
4913 5. The PIC port manages its own allocation of the general purpose
4914 registers, but makes no attempt to reuse them. As a result when
4915 compiling it soon runs out of general purpose registers. Some
4916 additional code was added to the files pcode.c and device.c to walk
4917 through the function call tree and rename the registers so that they
4927 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4934 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4936 Made bitfield a distinct type from bit so that bitfields
4937 convert as per ANSI C and bits retain their traditional
4938 boolean style behaviour. Implemented bitfield support in
4946 * src/ds390/gen.c: bit v bitfield split
4947 * src/z80/gen.c: New support for bitfields
4948 * support/regression/tests/bitfields.c: reenabled z80,
4951 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4953 Rules 246.x, 247.x relate to bitfields, the others speed up
4954 access to xdata mapped I/O devices.
4956 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4958 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4960 Cleaned up genPackBits and genUnpackBits and added two helper
4961 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4962 for literal assignments in genPackBits (thanks to Frieder for
4968 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4970 Fixed bug #748310 (pointer to function type mishandled when the
4971 function name is omitted). Also fixed a SIGSEGV when a function
4972 attribute (reentrant, etc) is used on a non-function or on a
4973 function but misplaced before the parameter list.
4975 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

5000 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5002 Made the constant following the "interrupt" keyword optional. If
5003 omitted, the function will not automatically be given an entry
5004 in the interrupt vector table (similar to #pragma NOIV, but
5005 less syntacticly kludgy). The interrupt number is also now
5006 range checked. Also fixed a bug in the high order bit example

5537 messages from optionsTable when a port is not configured, added
5538 support for the PIc16 port in the ports table, when executing
5539 the compiler with no port specified on command line, a default
5540 port is selected with the new macro DEFAULT_PORT which is
5541 defined in port.h, in setDefaultOptions() linkOptions is removed
5542 from initialization assignment, since now it is a set,
5543 parseCmdLine uses setParseWithComma for linkOptions, in
5544 linkEdit() linkOptions are accessed with new function indexSet()
5545 which returns the i'th item of a set variable. See SDCCset.c, in
5546 linkEdit() when calling buildCmdLine(), added linkOptions as
5547 last argument. Now users can pass arguments to gplink via the
5548 -Wl option, main() uses pic16glue() to glue up pic16 programs

5562 gpasm complaining and test the linkage with gplink, _linkCmd and
5563 _asmCmd changed to be more gplink and gpasm friendly
5564 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5565 produced an error when parsed, peep rule 12 is added to utilize
5566 movff, but it is commented out since the pCode does not support
5567 yet a command with 2 address arguments
5569 2003-05-18 <johan AT balder>
5571 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6589 2003-01-07 <johan AT balder>
6591 * src/SDCCast.c (decorateType): fixed bug #600035
6593 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6604 2003-01-06 <johan AT balder>
6606 * src/SDCCicode.c: fixed array add
6608 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6609 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6610 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6612 2003-01-04 <johan AT balder>
6614 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6616 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6617 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6619 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6620 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6629 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6630 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6632 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6634 * in \sdcc\as\mcs51\ changed these files in order to create an
6635 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6636 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6637 following files to include the previous two files: aslink.dsp,
6638 Makefile.aslink, Makefile.bcc, and Makefile.in.
6640 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6641 .adb instead of .cdb
6643 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6645 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6646 value from option --iram-size.
6648 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6650 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6653 2002-09-18 <wiml AT hhhh.org>
6655 * SDCClrange.h: exposed setFromRange() and setToRange()
6656 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6657 packRegsForAccUse() (bug 542397)
6658 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6659 multiple times and emitting the fetch operations more than once
6660 added aopGetUsesAcc() function to allow binary operators to
6661 fetch their operands in the correct order; made genMinus() emit
6662 compact code for X = LITERAL - Y
6664 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6665 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6666 sprintf() in line 1267.
6668 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6669 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6672 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6673 Changes to aslink (All the changes are marked with 'JCF'):
6675 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6678 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6679 area BSEG. Also moves, if possible, the DATA area down into the internal
6680 ram so more space is available.
6682 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6685 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6686 not bytes. Function summary() which creates a memory usage summary
6687 file with extension .mem. Reports of overlaping stack and small stack
6688 size. If the space for the stack is less than 16 bytes aslink trows a
6691 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6692 the 8051. Option 'y' for memory summary output file.
6694 Changes to sdcc (All the changes are marked with 'JCF'):
6696 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6698 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6699 overlaying area for it (uses RegBankUsed[4]).
6701 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6702 bank zero as used by default. By default aslink locates the stack
6703 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6704 the creation of the .mem file. Delegates the allocation of data area
6705 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6706 the begining of the stack area to aslink.
6708 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6709 glue() in SDCCglue.c creates an area for it.
6711 2002-09-03 Borut Razem <borut.razem AT siol.net>
6712 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6713 sdcc/src/pic/glue.c:
6714 introduced atexit() handler for teporay files removal in case of
6715 errors, assertions, ...
6717 2002-08-29 Borut Razem <borut.razem AT siol.net>
6718 * sdcc/support/cpp2/auto-host_vc_in.h:
6719 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6720 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6721 Maybe there is a similar problem with BORLANDC? It should be checked!
6723 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6724 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6725 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6726 was not executed, and the compiler (cl) launched a warning:
6727 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6729 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6730 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6732 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6733 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6735 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6736 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6737 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6738 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6739 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6740 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6741 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6742 - added Release configuration in VS projects
6743 - review of compiler an linker options
6744 - VC .exe files are generated in bin_vc directory, not to interfere
6745 with binaries generated from other projects (cygwin, mingw, bcc ...)
6747 * sdcc/src/yacc.dsp: added
6749 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6750 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6751 and insert the version number definitions from .version
6753 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6755 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6756 added - genarate auto-host.h using auto-host_vc_in.h as template
6759 removed from CVS, generated automatically
6761 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6762 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6764 2002-08-11 Borut Razem <borut.razem AT siol.net>
6765 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6767 2002-08-10 Borut Razem <borut.razem AT siol.net>
6768 * src/SDCCmain.c (main):
6769 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6770 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6771 The consequence was that some temporary files were not removed.
6774 unification of code in functions tempfilename() and tempfile():
6775 function tempnam() is defined in Visual Studio 6.0 and .NET
6777 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6779 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6780 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6781 - removed compiler command line option /WX: Treats all warnings as errors
6782 - update a list of source files, included into the project
6784 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6785 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6786 changed project type to Generic Project so that can be correcly converted to VS.NET project
6788 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6790 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6792 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6794 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6795 added return 0 statements after assert() to make compiler happy
6797 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6798 added newline in the def file to keep MSC compiler satisfied
6800 * sdcc/src/z80/gen.c:
6801 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6802 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6803 - solved MSC error in function aopDump()
6805 * sdcc_vc.h: define PREFIX as "\\sdcc"
6807 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6808 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6810 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6811 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6812 - Rewrote the register banking algorithm.
6813 - Added pCode live-range analysis to registers (for now, only non-used and
6814 singly-used registers optimized away)
6816 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6818 * 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.

6843 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6845 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6847 2002-03-28 Johan Knol <johan AT balder>
6849 * src/SDCCval.c: fixed bug #532436
6851 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6853 Added "char *Processor" field to the port structure.
6856 Added -p option. Allows port dependent processor to be specified.
6859 Initialized the new field char *Processor field to NULL in all ports
6862 Compiler generated registers for interrupt context saving
6863 were not getting allocated.
6865 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6868 Fixed left shift. Will promote the left side of a left shift
6869 if a) left shifting more than size of operand or b) when assigned
6870 to something size > size of left side
6872 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6874 tons of changes. Register allocation has been
6875 rewritten. Added customization for the various PICs. Flow
6876 analysis is restructured. ...
6882 Added. device.c is a PIC port hack to accomodate variations
6885 2002-03-13 Michael Hope <michaelh AT vroom>
6887 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6889 2002-03-04 johanknol <johanknol AT manik>
6891 * /src/SDCCval.c: fixed
6893 const unsigned char arr[][2] = { { 0, 1 } };

6896 2002-03-04 bela <bela AT manik>
6898 * /device/include/mcs51reg.h:
6899 ds89c420 register definition update

6980 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6982 * sdcc/src/SDCCloop.c:
6983 Previous fix was not good. basic blocks that have "break" or "return" are
6984 not really partof a loop , but live ranges used in these blocks should
6985 be live thru the entire loop, so set partOfLoop but don't add them to
6988 2002-02-21 <johan AT FRIJA>
6990 * src/SDCCcse.c: fixed bug #514308
6992 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6995 Fixed BUG #519583. If a conditional block ended in a return/break
6996 statement inside a loop, it was not being considered part of the loop.
6998 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7000 2002-02-10 Karl Bongers <karl AT turbobit.com>
7003 Fixed up SDCDB debugger somewhat. Updated debugger/README
7004 with lots of comments and notes.
7006 * device/examples/test2.c:
7007 Fix bug, "red" variable not being initialized(compiler complained).
7009 * device/examples/Makefile, examples/test3.c:
7010 Add Makefile in device/examples folder, compiles test3.c
7011 for use as a multiple module SDCDB test case.
7013 * sim/ucsim/cmd.src/cmdset.cc:
7014 Took out debug printfs in ucsim "next" command.
7017 Karl and Johan start ucsim XA support. Most dissassembly working,
7018 about 75% emulation done(plenty of work remaining).
7020 * sim/ucsim/z80.src:
7021 Add Z80 support to ucsim, add test-ucz80 regression test,
7022 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7023 Notice z80 compiler fails on examples/test3.c/crc code.
7025 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
