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

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

3377 loaded with the linker search paths (-L arguments) and the libraries
3378 to be linked with the current source (-l arguments). Changes
3379 currently will affect only the pic16 port.
3380 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3381 include path the port specific paths and port specific libraries,
3382 * gplink command now contains the $3 argument,
3383 * src/pic16/device.h,
3384 * src/pic16/device.c,: structure PIC_device is made public and

3400 Documenting changes from previous commits.
3401 * configure.in (version 1.56),
3402 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3403 when generating output files to configure the pic16 library,
3404 but now I've commented it out, since gputils aren't installed in the
3405 SF compile farm, so library won't compile
3407 * device/lib/Makefile.in (version 1.56): initially I've added in
3408 target 'all' the prerequestive 'model-pic16' so it compiled the
3409 pic16 library, but now I've commented it out for the same reasons
3411 * added targets 'model-pic16' and 'objects-pic16' to compile the
3413 * added target 'port-specific-objects-pic16' to handle the
3414 generated libraries and copy them into the build/ directory
3415 * added target 'clean-intermediate-pic16' to clean intermediate
3416 files into pic16 directory
3417 * in target 'installdirs' added line to create directory pic16 in

3662 * src/SDCCast.c (decorateType),
3663 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3664 LEFT_OP (left shift)
3666 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3668 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3669 (default behaviour).
3671 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3673 A python script to validate compiler diagnostic messages. It can be
3674 used to verify that sdcc complains about bad c source code and
3675 gives a good location of the error.
3676 * support/valdiag/Makefile,
3677 * support/valdiag/valdiag.py,
3678 * support/valdiag/tests/*
3680 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3695 Bug reported from Jesus Calvino-Fraga
3697 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3699 * sdcc.spec: updated
3700 * device/include/Makefile.in: don't install CVS directories
3701 * device/lib/Makefile.in: added removal of CVS directories after install
3702 * doc/Makefile: fixed install, added local_icons
3703 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3704 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3705 * src/ds390/gen.c (genRightShift): fixed bug #870788

3708 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3710 PIC16 port related changes:
3711 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3712 added variable stackPos,
3714 * gen.c: genCall, assignResultValue: added support for
3715 pushing/retrieving function parameters to/from stack,
3716 genFunction,genEndFunction: setup stack frame for the
3718 genAddrOf: will be changed according to bug 863624
3720 * added files genutils.c and genutils.h which contain gen*
3721 debugged and optimised functions extracted from gen.c
3723 * glue.c: added variable 'externs' which holds extern symbols,
3724 pic16emitRegularMap: is modified to properly handle relocatable
3725 symbols under the new scheme,
3726 pic16createInterruptVect: is modified
3727 pic16printPublics: is modified to emit 'global' assembler directives,
3728 added pic16_printExterns to print extern symbols,
3729 pic16glue: initializes stack/frame pointer in the beginning of
3730 the assembly output. Temporary hack, will be corrected later,
3731 because gplink yet does not support stack and SDCC does not
3732 yet support a type of crt0.o object to create the final binary.
3734 * Removed many lines that contain 8051 legacy code.
3735 * The code is finally placed under a 'code' directive.
3736 * Added port specific options.
3738 * _process_pragma: simplified since now we do not need *special*
3739 include file to define SFR registers. But a separate header
3740 will be needed. This will be developed later.
3741 * _pic16_parseOptions: added, parses port specific options:
3742 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3743 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3744 --preplace-udata-with=
3746 * _pic16_setDefaultOptions: modified to initialize section names,
3747 but hack is temporarly out of order since it needs improvement.
3748 * _pic16_genAssemblerPreamble: configuration words are emitted by
3749 their address instead of their name. This part is incomplete and
3750 supports only the 18Fxx2 devices. Other devices will emit an error
3751 during assembly since they do not contain the same set of config
3753 * _pic16_genIVT: is modified,
3755 * pcode.c: added definitions for some hardware registers that are needed
3757 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3758 All PCI entries are updated. Now LFSR is supported.
3759 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3760 * added pic16_newpCodeOpLit2 to support instructions with
3761 two literal arguments
3762 * pic16_pCode2str: corrected code that emits assembler instructions
3763 with two literal operands and those that have an access bit modifier
3764 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3765 this fixes a bug which caused some labels to be lost, when an
3766 assembler directive was added, i.e. banksel,
3767 * pic16_FixRegisterBanking: improved logic that causes the insertion
3769 * InlineFunction: functions that are called once, are not any more
3770 inlined. This can be a port option in the future,
3772 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3774 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3775 hold the corresponding uninitialized symbols,
3776 * pic16_allocProcessorRegister: registers have explicit marked the
3778 * pic16_allocInternalRegister: registers are explicit marked as
3780 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3781 processing list, so bit registers were lost,
3784 * ralloc.h: added field 'accessBank' and original symbol operand
3785 in register definition,
3786 * removed the field isMapped from register definition,
3788 ** Several functions have been removed from various sources:
3789 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3790 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3791 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3792 pic16_assignRelocatableRegisters
3794 ** others have been introduced:
3795 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3796 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3798 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3800 * support/scripts/inc2h.pl: changed definition of BIT_AT
3801 to emit 'sbit at' instead of 'bit at'. This was a request.
3803 PIC16 port related preliminary changes:
3804 * gen.c: prefixed function popRegFromString with
3805 pic16_ and all references to it corrected
3806 * pcode.c: all pic16_pc_* hardware registers prefixed
3807 with underscore (_),
3808 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3809 * ralloc.c: newReg(): when register is REG_SFR then
3810 set address to rIdx,
3811 pic16_allocProcessorRegister(): marks register wasUsed=0
3812 pic16_writeUsedRegs(): added a call to assign processor
3813 registers via pic16_assignFixedRegisters
3815 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3817 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3818 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3819 variables in unused register banks. Also the SSEG is placed
3820 wherever there is enough space for it, and IDATA can be anywhere
3821 in internal RAM. For now compile using -Wl-Y[stack_size].
3822 The mem file is different for this option as well, since it
3823 makes no sense of talking about DSEG lenght.
3825 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3827 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3828 in certain cases, e.g. when ROM assignment, patch provided
3829 from Albert den Haan.
3831 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4070 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4072 * src/SDCCast.c (decorateType): disabled a transformation I added in
4073 revision 1.188 (access to fields of a structure at an absolute address);
4074 it breaks with bitfields, extern declarations, and gcse analysis.
4075 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4076 could be assigned through a pointer, so don't complain.
4077 * src/SDCCast.c (astErrors),
4079 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4081 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

4833 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4834 fetching of the pointer
4835 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4836 copied from genNearPointerSet()
4837 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4838 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4854 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4855 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4856 type for bits was changed. It resulted in bit variables becoming
4857 global, which is not permitted in PIC 14 assembly output.
4859 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4874 A few small changes that speed up the peephole optimizer.
4878 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4880 Try to make the peephole optimizer smarter by maintaining
4881 an association between the assembly source code and the
4882 iCodes that originated them. Put this information to use
4883 with a new peephole rule condition "notVolatile" so that
4884 the rules can be aggressive yet still safe.
4889 * src/mcs51/peeph.def
4891 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4895 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4896 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4897 if the left or right operand symbols have the accuse flag set.
4899 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4901 Changed the type of the result of the ! (NOT) operator to char;
4902 previously it returned the same type as the source. This allows
4903 us to eliminate all the genFloatNot functions (all of its target
4904 implementations were very buggy) since !float can use the same
4907 * src/SDCCicode.c (ast2iCode): ! returns char

4916 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4917 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4918 during interrupts. Ensure WSAVE is located at a shared bank address.
4919 2. Fixed page selection in some places
4920 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4921 the registers name strings.
4922 4. Fixed "signed / unsigned compare" compiler warnings.
4923 5. The PIC port manages its own allocation of the general purpose
4924 registers, but makes no attempt to reuse them. As a result when
4925 compiling it soon runs out of general purpose registers. Some
4926 additional code was added to the files pcode.c and device.c to walk
4927 through the function call tree and rename the registers so that they
4937 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4938 genPlus() & genMinus() when the result is the same as left or right

4944 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4946 Made bitfield a distinct type from bit so that bitfields
4947 convert as per ANSI C and bits retain their traditional
4948 boolean style behaviour. Implemented bitfield support in
4956 * src/ds390/gen.c: bit v bitfield split
4957 * src/z80/gen.c: New support for bitfields
4958 * support/regression/tests/bitfields.c: reenabled z80,
4961 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4963 Rules 246.x, 247.x relate to bitfields, the others speed up
4964 access to xdata mapped I/O devices.
4966 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4968 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4970 Cleaned up genPackBits and genUnpackBits and added two helper
4971 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4972 for literal assignments in genPackBits (thanks to Frieder for
4978 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4980 Fixed bug #748310 (pointer to function type mishandled when the
4981 function name is omitted). Also fixed a SIGSEGV when a function
4982 attribute (reentrant, etc) is used on a non-function or on a
4983 function but misplaced before the parameter list.
4985 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4987 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4988 * support/Util/SDCCerr.h,

5010 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5012 Made the constant following the "interrupt" keyword optional. If
5013 omitted, the function will not automatically be given an entry
5014 in the interrupt vector table (similar to #pragma NOIV, but
5015 less syntacticly kludgy). The interrupt number is also now
5016 range checked. Also fixed a bug in the high order bit example

5547 messages from optionsTable when a port is not configured, added
5548 support for the PIc16 port in the ports table, when executing
5549 the compiler with no port specified on command line, a default
5550 port is selected with the new macro DEFAULT_PORT which is
5551 defined in port.h, in setDefaultOptions() linkOptions is removed
5552 from initialization assignment, since now it is a set,
5553 parseCmdLine uses setParseWithComma for linkOptions, in
5554 linkEdit() linkOptions are accessed with new function indexSet()
5555 which returns the i'th item of a set variable. See SDCCset.c, in
5556 linkEdit() when calling buildCmdLine(), added linkOptions as
5557 last argument. Now users can pass arguments to gplink via the
5558 -Wl option, main() uses pic16glue() to glue up pic16 programs

5572 gpasm complaining and test the linkage with gplink, _linkCmd and
5573 _asmCmd changed to be more gplink and gpasm friendly
5574 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5575 produced an error when parsed, peep rule 12 is added to utilize
5576 movff, but it is commented out since the pCode does not support
5577 yet a command with 2 address arguments
5579 2003-05-18 <johan AT balder>
5581 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6597 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6599 2003-01-07 <johan AT balder>
6601 * src/SDCCast.c (decorateType): fixed bug #600035
6603 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6604 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6614 2003-01-06 <johan AT balder>
6616 * src/SDCCicode.c: fixed array add
6618 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6619 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6620 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6622 2003-01-04 <johan AT balder>
6624 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6626 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6627 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6629 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6630 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6631 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6633 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

6636 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6637 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6639 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6640 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6642 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6644 * in \sdcc\as\mcs51\ changed these files in order to create an
6645 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6646 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6647 following files to include the previous two files: aslink.dsp,
6648 Makefile.aslink, Makefile.bcc, and Makefile.in.
6650 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6651 .adb instead of .cdb
6653 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6655 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6656 value from option --iram-size.
6658 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6660 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6663 2002-09-18 <wiml AT hhhh.org>
6665 * SDCClrange.h: exposed setFromRange() and setToRange()
6666 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6667 packRegsForAccUse() (bug 542397)
6668 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6669 multiple times and emitting the fetch operations more than once
6670 added aopGetUsesAcc() function to allow binary operators to
6671 fetch their operands in the correct order; made genMinus() emit
6672 compact code for X = LITERAL - Y
6674 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6675 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6676 sprintf() in line 1267.
6678 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6679 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6682 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6683 Changes to aslink (All the changes are marked with 'JCF'):
6685 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6688 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6689 area BSEG. Also moves, if possible, the DATA area down into the internal
6690 ram so more space is available.
6692 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6695 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6696 not bytes. Function summary() which creates a memory usage summary
6697 file with extension .mem. Reports of overlaping stack and small stack
6698 size. If the space for the stack is less than 16 bytes aslink trows a
6701 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6702 the 8051. Option 'y' for memory summary output file.
6704 Changes to sdcc (All the changes are marked with 'JCF'):
6706 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6708 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6709 overlaying area for it (uses RegBankUsed[4]).
6711 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6712 bank zero as used by default. By default aslink locates the stack
6713 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6714 the creation of the .mem file. Delegates the allocation of data area
6715 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6716 the begining of the stack area to aslink.
6718 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6719 glue() in SDCCglue.c creates an area for it.
6721 2002-09-03 Borut Razem <borut.razem AT siol.net>
6722 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6723 sdcc/src/pic/glue.c:
6724 introduced atexit() handler for teporay files removal in case of
6725 errors, assertions, ...
6727 2002-08-29 Borut Razem <borut.razem AT siol.net>
6728 * sdcc/support/cpp2/auto-host_vc_in.h:
6729 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6730 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6731 Maybe there is a similar problem with BORLANDC? It should be checked!
6733 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6734 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6735 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6736 was not executed, and the compiler (cl) launched a warning:
6737 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6739 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6740 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6742 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6743 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6745 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6746 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6747 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6748 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6749 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6750 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6751 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6752 - added Release configuration in VS projects
6753 - review of compiler an linker options
6754 - VC .exe files are generated in bin_vc directory, not to interfere
6755 with binaries generated from other projects (cygwin, mingw, bcc ...)
6757 * sdcc/src/yacc.dsp: added
6759 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6760 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6761 and insert the version number definitions from .version
6763 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6765 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6766 added - genarate auto-host.h using auto-host_vc_in.h as template
6769 removed from CVS, generated automatically
6771 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6772 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6774 2002-08-11 Borut Razem <borut.razem AT siol.net>
6775 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6777 2002-08-10 Borut Razem <borut.razem AT siol.net>
6778 * src/SDCCmain.c (main):
6779 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6780 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6781 The consequence was that some temporary files were not removed.
6784 unification of code in functions tempfilename() and tempfile():
6785 function tempnam() is defined in Visual Studio 6.0 and .NET
6787 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6789 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6790 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6791 - removed compiler command line option /WX: Treats all warnings as errors
6792 - update a list of source files, included into the project
6794 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6795 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6796 changed project type to Generic Project so that can be correcly converted to VS.NET project
6798 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6800 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6802 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6804 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6805 added return 0 statements after assert() to make compiler happy
6807 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6808 added newline in the def file to keep MSC compiler satisfied
6810 * sdcc/src/z80/gen.c:
6811 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6812 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6813 - solved MSC error in function aopDump()
6815 * sdcc_vc.h: define PREFIX as "\\sdcc"
6817 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6818 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6820 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6821 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6822 - Rewrote the register banking algorithm.
6823 - Added pCode live-range analysis to registers (for now, only non-used and
6824 singly-used registers optimized away)
6826 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6828 * 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.
6830 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6831 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6833 2002-04-22 Michael Hope <michaelh AT vroom>

6853 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6855 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6857 2002-03-28 Johan Knol <johan AT balder>
6859 * src/SDCCval.c: fixed bug #532436
6861 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6863 Added "char *Processor" field to the port structure.
6866 Added -p option. Allows port dependent processor to be specified.
6869 Initialized the new field char *Processor field to NULL in all ports
6872 Compiler generated registers for interrupt context saving
6873 were not getting allocated.
6875 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6878 Fixed left shift. Will promote the left side of a left shift
6879 if a) left shifting more than size of operand or b) when assigned
6880 to something size > size of left side
6882 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6884 tons of changes. Register allocation has been
6885 rewritten. Added customization for the various PICs. Flow
6886 analysis is restructured. ...
6892 Added. device.c is a PIC port hack to accomodate variations
6895 2002-03-13 Michael Hope <michaelh AT vroom>
6897 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6899 2002-03-04 johanknol <johanknol AT manik>
6901 * /src/SDCCval.c: fixed
6903 const unsigned char arr[][2] = { { 0, 1 } };
6904 t18.c:1: error: Initializer element is not constant
6906 2002-03-04 bela <bela AT manik>
6908 * /device/include/mcs51reg.h:
6909 ds89c420 register definition update
6911 2002-03-03 <johan AT FRIJA>

6990 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6992 * sdcc/src/SDCCloop.c:
6993 Previous fix was not good. basic blocks that have "break" or "return" are
6994 not really partof a loop , but live ranges used in these blocks should
6995 be live thru the entire loop, so set partOfLoop but don't add them to
6998 2002-02-21 <johan AT FRIJA>
7000 * src/SDCCcse.c: fixed bug #514308
7002 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7005 Fixed BUG #519583. If a conditional block ended in a return/break
7006 statement inside a loop, it was not being considered part of the loop.
7008 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7010 2002-02-10 Karl Bongers <karl AT turbobit.com>
7013 Fixed up SDCDB debugger somewhat. Updated debugger/README
7014 with lots of comments and notes.
7016 * device/examples/test2.c:
7017 Fix bug, "red" variable not being initialized(compiler complained).
7019 * device/examples/Makefile, examples/test3.c:
7020 Add Makefile in device/examples folder, compiles test3.c
7021 for use as a multiple module SDCDB test case.
7023 * sim/ucsim/cmd.src/cmdset.cc:
7024 Took out debug printfs in ucsim "next" command.
7027 Karl and Johan start ucsim XA support. Most dissassembly working,
7028 about 75% emulation done(plenty of work remaining).
7030 * sim/ucsim/z80.src:
7031 Add Z80 support to ucsim, add test-ucz80 regression test,
7032 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
