234 functions, ctype functions and macros and some functions of the
235 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
236 be extensively tested in the future. Standard disclaimer here.

252 with variables grater than 1 byte in size, so new code is disabled,
253 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
255 * (genCast): began a fix to optimize the casting of a bit to another
256 bit, now assigning a bitfield to another bitfield will fail, sorry,

3193 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3195 * src/SDCCast.c: added an additional type flow in decorateType() of
3196 opposite direction, see feature request #860006; it's enabled at runtime
3197 by setting the environment variable SDCC_NEWTYPEFLOW
3198 * src/SDCCast.h: changed prototype of decorateType()
3199 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()

3279 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3281 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3282 loaded with the linker search paths (-L arguments) and the libraries
3283 to be linked with the current source (-l arguments). Changes
3284 currently will affect only the pic16 port.
3285 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3286 include path the port specific paths and port specific libraries,
3287 * gplink command now contains the $3 argument,
3288 * src/pic16/device.h,
3289 * src/pic16/device.c,: structure PIC_device is made public and
3290 renamed to PIC16_device, the same for variable Pics which is renamed

3305 Documenting changes from previous commits.
3306 * configure.in (version 1.56),
3307 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3308 when generating output files to configure the pic16 library,
3309 but now I've commented it out, since gputils aren't installed in the
3310 SF compile farm, so library won't compile
3312 * device/lib/Makefile.in (version 1.56): initially I've added in
3313 target 'all' the prerequestive 'model-pic16' so it compiled the
3314 pic16 library, but now I've commented it out for the same reasons
3316 * added targets 'model-pic16' and 'objects-pic16' to compile the
3318 * added target 'port-specific-objects-pic16' to handle the
3319 generated libraries and copy them into the build/ directory
3320 * added target 'clean-intermediate-pic16' to clean intermediate
3321 files into pic16 directory
3322 * in target 'installdirs' added line to create directory pic16 in

3626 debugged and optimised functions extracted from gen.c
3628 * glue.c: added variable 'externs' which holds extern symbols,
3629 pic16emitRegularMap: is modified to properly handle relocatable
3630 symbols under the new scheme,
3631 pic16createInterruptVect: is modified
3632 pic16printPublics: is modified to emit 'global' assembler directives,
3633 added pic16_printExterns to print extern symbols,
3634 pic16glue: initializes stack/frame pointer in the beginning of
3635 the assembly output. Temporary hack, will be corrected later,
3636 because gplink yet does not support stack and SDCC does not
3637 yet support a type of crt0.o object to create the final binary.
3639 * Removed many lines that contain 8051 legacy code.
3640 * The code is finally placed under a 'code' directive.
3641 * Added port specific options.
3643 * _process_pragma: simplified since now we do not need *special*
3644 include file to define SFR registers. But a separate header
3645 will be needed. This will be developed later.
3646 * _pic16_parseOptions: added, parses port specific options:
3647 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3648 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3649 --preplace-udata-with=
3651 * _pic16_setDefaultOptions: modified to initialize section names,
3652 but hack is temporarly out of order since it needs improvement.
3653 * _pic16_genAssemblerPreamble: configuration words are emitted by
3654 their address instead of their name. This part is incomplete and
3655 supports only the 18Fxx2 devices. Other devices will emit an error
3656 during assembly since they do not contain the same set of config
3658 * _pic16_genIVT: is modified,
3660 * pcode.c: added definitions for some hardware registers that are needed
3662 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3663 All PCI entries are updated. Now LFSR is supported.
3664 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3665 * added pic16_newpCodeOpLit2 to support instructions with
3666 two literal arguments
3667 * pic16_pCode2str: corrected code that emits assembler instructions
3668 with two literal operands and those that have an access bit modifier
3669 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3670 this fixes a bug which caused some labels to be lost, when an
3671 assembler directive was added, i.e. banksel,
3672 * pic16_FixRegisterBanking: improved logic that causes the insertion
3674 * InlineFunction: functions that are called once, are not any more
3675 inlined. This can be a port option in the future,
3677 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3679 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3680 hold the corresponding uninitialized symbols,
3681 * pic16_allocProcessorRegister: registers have explicit marked the
3683 * pic16_allocInternalRegister: registers are explicit marked as
3685 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3686 processing list, so bit registers were lost,
3689 * ralloc.h: added field 'accessBank' and original symbol operand
3690 in register definition,
3691 * removed the field isMapped from register definition,
3693 ** Several functions have been removed from various sources:
3694 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3695 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3696 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3697 pic16_assignRelocatableRegisters
3699 ** others have been introduced:
3700 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3701 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3703 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3705 * support/scripts/inc2h.pl: changed definition of BIT_AT
3706 to emit 'sbit at' instead of 'bit at'. This was a request.
3708 PIC16 port related preliminary changes:
3709 * gen.c: prefixed function popRegFromString with
3710 pic16_ and all references to it corrected
3711 * pcode.c: all pic16_pc_* hardware registers prefixed
3712 with underscore (_),
3713 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3714 * ralloc.c: newReg(): when register is REG_SFR then
3715 set address to rIdx,
3716 pic16_allocProcessorRegister(): marks register wasUsed=0
3717 pic16_writeUsedRegs(): added a call to assign processor
3718 registers via pic16_assignFixedRegisters
3720 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3722 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3723 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3724 variables in unused register banks. Also the SSEG is placed
3725 wherever there is enough space for it, and IDATA can be anywhere
3726 in internal RAM. For now compile using -Wl-Y[stack_size].
3727 The mem file is different for this option as well, since it
3728 makes no sense of talking about DSEG lenght.
3730 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3732 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3733 in certain cases, e.g. when ROM assignment, patch provided
3734 from Albert den Haan.
3736 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3892 multiply defined with mismatching "at" address.
3894 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3975 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3977 * src/SDCCast.c (decorateType): disabled a transformation I added in
3978 revision 1.188 (access to fields of a structure at an absolute address);
3979 it breaks with bitfields, extern declarations, and gcse analysis.
3980 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3981 could be assigned through a pointer, so don't complain.
3982 * src/SDCCast.c (astErrors),
3984 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4084 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4086 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4087 uninitialized variables) for the mcs51. Set environment variable

4738 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4739 fetching of the pointer
4740 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4741 copied from genNearPointerSet()
4742 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4743 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4759 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4760 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4761 type for bits was changed. It resulted in bit variables becoming
4762 global, which is not permitted in PIC 14 assembly output.
4764 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4766 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4779 A few small changes that speed up the peephole optimizer.
4783 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4785 Try to make the peephole optimizer smarter by maintaining
4786 an association between the assembly source code and the
4787 iCodes that originated them. Put this information to use
4788 with a new peephole rule condition "notVolatile" so that
4789 the rules can be aggressive yet still safe.
4794 * src/mcs51/peeph.def
4796 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4800 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4801 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4802 if the left or right operand symbols have the accuse flag set.
4804 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4806 Changed the type of the result of the ! (NOT) operator to char;
4807 previously it returned the same type as the source. This allows
4808 us to eliminate all the genFloatNot functions (all of its target
4809 implementations were very buggy) since !float can use the same
4812 * src/SDCCicode.c (ast2iCode): ! returns char

4821 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4822 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4823 during interrupts. Ensure WSAVE is located at a shared bank address.
4824 2. Fixed page selection in some places
4825 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4826 the registers name strings.
4827 4. Fixed "signed / unsigned compare" compiler warnings.
4828 5. The PIC port manages its own allocation of the general purpose
4829 registers, but makes no attempt to reuse them. As a result when
4830 compiling it soon runs out of general purpose registers. Some
4831 additional code was added to the files pcode.c and device.c to walk
4832 through the function call tree and rename the registers so that they
4842 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4843 genPlus() & genMinus() when the result is the same as left or right

4849 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4851 Made bitfield a distinct type from bit so that bitfields
4852 convert as per ANSI C and bits retain their traditional
4853 boolean style behaviour. Implemented bitfield support in
4861 * src/ds390/gen.c: bit v bitfield split
4862 * src/z80/gen.c: New support for bitfields
4863 * support/regression/tests/bitfields.c: reenabled z80,
4866 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4868 Rules 246.x, 247.x relate to bitfields, the others speed up
4869 access to xdata mapped I/O devices.
4871 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4873 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4875 Cleaned up genPackBits and genUnpackBits and added two helper
4876 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4877 for literal assignments in genPackBits (thanks to Frieder for
4883 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4885 Fixed bug #748310 (pointer to function type mishandled when the
4886 function name is omitted). Also fixed a SIGSEGV when a function
4887 attribute (reentrant, etc) is used on a non-function or on a
4888 function but misplaced before the parameter list.
4890 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4892 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4893 * support/Util/SDCCerr.h,
4894 * support/Util/SDCCerr.c: Added func attr misuse error msg

4915 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4917 Made the constant following the "interrupt" keyword optional. If
4918 omitted, the function will not automatically be given an entry
4919 in the interrupt vector table (similar to #pragma NOIV, but
4920 less syntacticly kludgy). The interrupt number is also now
4921 range checked. Also fixed a bug in the high order bit example

4929 * support/Util/SDCCerr.h
4932 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4934 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4935 * src/SDCCicode.c (operandOperation): rewritten some ops
4936 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4937 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4939 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4940 be re-activated by defining REDUCE_LITERALS)
4941 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4942 unsigned, but are signed by default
4943 * src/SDCCval.c (constVal): rearranged
4944 * src/SDCCval.c (valMod): preliminary fix
4945 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4987 constants are unsigned; added recognition of "u" flag for unsigned
4988 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4989 * src/SDCCval.c (valDiv, valMod): fixed signdness
4990 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4991 signedness of modulo, left and right shift

5450 * src/SDCCmain.c: linkOptions is changed to set *,
5451 added if/endif conditional macros to remove options help
5452 messages from optionsTable when a port is not configured, added
5453 support for the PIc16 port in the ports table, when executing
5454 the compiler with no port specified on command line, a default
5455 port is selected with the new macro DEFAULT_PORT which is
5456 defined in port.h, in setDefaultOptions() linkOptions is removed
5457 from initialization assignment, since now it is a set,
5458 parseCmdLine uses setParseWithComma for linkOptions, in
5459 linkEdit() linkOptions are accessed with new function indexSet()
5460 which returns the i'th item of a set variable. See SDCCset.c, in
5461 linkEdit() when calling buildCmdLine(), added linkOptions as
5462 last argument. Now users can pass arguments to gplink via the
5463 -Wl option, main() uses pic16glue() to glue up pic16 programs

5476 * src/pic16/main.c: __config directives are commented out to stop
5477 gpasm complaining and test the linkage with gplink, _linkCmd and
5478 _asmCmd changed to be more gplink and gpasm friendly
5479 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5480 produced an error when parsed, peep rule 12 is added to utilize
5481 movff, but it is commented out since the pCode does not support
5482 yet a command with 2 address arguments
5484 2003-05-18 <johan AT balder>
5486 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5513 2003-05-11 Borut Razem <borut.razem AT siol.net>
5515 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5516 the path of bin directory, so that PATH is the only env. variable, which has to be set
5517 in case of standard installation.
5518 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6545 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6547 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6549 * in \sdcc\as\mcs51\ changed these files in order to create an
6550 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6551 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6552 following files to include the previous two files: aslink.dsp,
6553 Makefile.aslink, Makefile.bcc, and Makefile.in.
6555 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6556 .adb instead of .cdb
6558 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6560 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6561 value from option --iram-size.
6563 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6565 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6568 2002-09-18 <wiml AT hhhh.org>
6570 * SDCClrange.h: exposed setFromRange() and setToRange()
6571 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6572 packRegsForAccUse() (bug 542397)
6573 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6574 multiple times and emitting the fetch operations more than once
6575 added aopGetUsesAcc() function to allow binary operators to
6576 fetch their operands in the correct order; made genMinus() emit
6577 compact code for X = LITERAL - Y
6579 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6580 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6581 sprintf() in line 1267.
6583 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6584 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6587 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6588 Changes to aslink (All the changes are marked with 'JCF'):
6590 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6593 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6594 area BSEG. Also moves, if possible, the DATA area down into the internal
6595 ram so more space is available.
6597 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6600 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6601 not bytes. Function summary() which creates a memory usage summary
6602 file with extension .mem. Reports of overlaping stack and small stack
6603 size. If the space for the stack is less than 16 bytes aslink trows a
6606 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6607 the 8051. Option 'y' for memory summary output file.
6609 Changes to sdcc (All the changes are marked with 'JCF'):
6611 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6613 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6614 overlaying area for it (uses RegBankUsed[4]).
6616 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6617 bank zero as used by default. By default aslink locates the stack
6618 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6619 the creation of the .mem file. Delegates the allocation of data area
6620 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6621 the begining of the stack area to aslink.
6623 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6624 glue() in SDCCglue.c creates an area for it.
6626 2002-09-03 Borut Razem <borut.razem AT siol.net>
6627 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6628 sdcc/src/pic/glue.c:
6629 introduced atexit() handler for teporay files removal in case of
6630 errors, assertions, ...
6632 2002-08-29 Borut Razem <borut.razem AT siol.net>
6633 * sdcc/support/cpp2/auto-host_vc_in.h:
6634 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6635 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6636 Maybe there is a similar problem with BORLANDC? It should be checked!
6638 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6639 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6640 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6641 was not executed, and the compiler (cl) launched a warning:
6642 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6644 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6645 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6647 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6648 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6650 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6651 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6652 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6653 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6654 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6655 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6656 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6657 - added Release configuration in VS projects
6658 - review of compiler an linker options
6659 - VC .exe files are generated in bin_vc directory, not to interfere
6660 with binaries generated from other projects (cygwin, mingw, bcc ...)
6662 * sdcc/src/yacc.dsp: added
6664 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6665 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6666 and insert the version number definitions from .version
6668 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6670 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6671 added - genarate auto-host.h using auto-host_vc_in.h as template
6674 removed from CVS, generated automatically
6676 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6677 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6679 2002-08-11 Borut Razem <borut.razem AT siol.net>
6680 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6682 2002-08-10 Borut Razem <borut.razem AT siol.net>
6683 * src/SDCCmain.c (main):
6684 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6685 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6686 The consequence was that some temporary files were not removed.
6689 unification of code in functions tempfilename() and tempfile():
6690 function tempnam() is defined in Visual Studio 6.0 and .NET
6692 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6694 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6695 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6696 - removed compiler command line option /WX: Treats all warnings as errors
6697 - update a list of source files, included into the project
6699 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6700 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6701 changed project type to Generic Project so that can be correcly converted to VS.NET project
6703 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6705 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6707 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6709 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6710 added return 0 statements after assert() to make compiler happy
6712 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6713 added newline in the def file to keep MSC compiler satisfied
6715 * sdcc/src/z80/gen.c:
6716 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6717 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6718 - solved MSC error in function aopDump()
6720 * sdcc_vc.h: define PREFIX as "\\sdcc"
6722 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6723 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6725 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6726 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6727 - Rewrote the register banking algorithm.
6728 - Added pCode live-range analysis to registers (for now, only non-used and
6729 singly-used registers optimized away)
6731 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6733 * 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.
6735 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6736 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

6762 2002-03-28 Johan Knol <johan AT balder>
6764 * src/SDCCval.c: fixed bug #532436
6766 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6768 Added "char *Processor" field to the port structure.
6771 Added -p option. Allows port dependent processor to be specified.
6774 Initialized the new field char *Processor field to NULL in all ports
6777 Compiler generated registers for interrupt context saving
6778 were not getting allocated.
6780 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6783 Fixed left shift. Will promote the left side of a left shift
6784 if a) left shifting more than size of operand or b) when assigned
6785 to something size > size of left side
6787 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6789 tons of changes. Register allocation has been
6790 rewritten. Added customization for the various PICs. Flow
6791 analysis is restructured. ...
6797 Added. device.c is a PIC port hack to accomodate variations
6800 2002-03-13 Michael Hope <michaelh AT vroom>
6802 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6895 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6897 * sdcc/src/SDCCloop.c:
6898 Previous fix was not good. basic blocks that have "break" or "return" are
6899 not really partof a loop , but live ranges used in these blocks should
6900 be live thru the entire loop, so set partOfLoop but don't add them to
6903 2002-02-21 <johan AT FRIJA>
6905 * src/SDCCcse.c: fixed bug #514308
6907 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6911 statement inside a loop, it was not being considered part of the loop.
6913 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6915 2002-02-10 Karl Bongers <karl AT turbobit.com>
6918 Fixed up SDCDB debugger somewhat. Updated debugger/README
6919 with lots of comments and notes.
6921 * device/examples/test2.c:
6922 Fix bug, "red" variable not being initialized(compiler complained).
6924 * device/examples/Makefile, examples/test3.c:
6925 Add Makefile in device/examples folder, compiles test3.c
6926 for use as a multiple module SDCDB test case.
6928 * sim/ucsim/cmd.src/cmdset.cc:
6929 Took out debug printfs in ucsim "next" command.
6932 Karl and Johan start ucsim XA support. Most dissassembly working,
6933 about 75% emulation done(plenty of work remaining).
6935 * sim/ucsim/z80.src:
6936 Add Z80 support to ucsim, add test-ucz80 regression test,
6937 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6973 set preprocessor defines (depending on options)
6975 * src/SDCCicode.c, src/SDCCicode.h:
6976 changes made to handle multiple sends & receives
6979 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
