457 Large cummulative patch for pic16 port.
458 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
459 to call when a stack overflow occurs,
460 * (malloc.h): added CVS Id tag,
461 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
463 * added libc directory. The current version of LibC contains string
464 functions, ctype functions and macros and some functions of the
465 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
466 be extensively tested in the future. Standard disclaimer here.
467 Library is not automatically build yet. But one can build it by
468 invoking 'make' inside the libc directory.
469 * added ADC library under libio. Preliminary version yet.
471 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
472 * src/pic16/gen.c (aopForRemat): asmop size is filled by
473 aopForRemat() now and not by pic16_aopOp(),
474 * (pic16_popGetTempReg): removed warning messgae when allocating
475 temporary registers, its a buggy feature and will be removed,
476 * (pic16_popGet): set register instance field in AOP_CRY,
477 * (pic16_outBitC): fixed for results in size greater than 1,
478 * (genUminusFloat): fixed for pic16, ported code from mcs51,
479 * (pic16_storeForReturn): optimized return of 0,
480 * (genCmp): experimental code for new genCmp which uses PIC18's
481 special compare&skip instructions. Initial tests fail some times
482 with variables grater than 1 byte in size, so new code is disabled,
483 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
485 * (genCast): began a fix to optimize the casting of a bit to another
486 bit, now assigning a bitfield to another bitfield will fail, sorry,
487 * src/pic16/main.c: disabled the use of lr-support feature,
488 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
489 * added some function prototypes, added function _debugf prototype,
490 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
491 bits with offset (case PO_GPR_BIT),
492 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
494 * (isBankInstruction): modified to return 0 for no banking instruction,
495 and 1 for banking instruction,
496 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
497 caused stop processing pCodes after a inline assembly block,
498 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
499 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
500 registers when it shouldn't,
501 * src/pic16/ralloc.c (allocReg): add preliminary support for
502 supporting a limited set of temporary registers,
504 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
506 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
507 genDataPointerSet): ensure assignments always copy in MSB to LSB
509 (loadRegFromAop): recognize CLRH optimization,
510 (genFunction): optimize RECEIVE iCodes in reentrant functions
512 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
514 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
515 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
517 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
518 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be

524 * device/lib/_gptrgetc.c (_gptrgetc),
525 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
526 instead of sjmp to ret

3509 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3511 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3512 loaded with the linker search paths (-L arguments) and the libraries
3513 to be linked with the current source (-l arguments). Changes
3514 currently will affect only the pic16 port.
3515 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3516 include path the port specific paths and port specific libraries,
3517 * gplink command now contains the $3 argument,
3518 * src/pic16/device.h,
3519 * src/pic16/device.c,: structure PIC_device is made public and
3520 renamed to PIC16_device, the same for variable Pics which is renamed

3535 Documenting changes from previous commits.
3536 * configure.in (version 1.56),
3537 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3538 when generating output files to configure the pic16 library,
3539 but now I've commented it out, since gputils aren't installed in the
3540 SF compile farm, so library won't compile
3542 * device/lib/Makefile.in (version 1.56): initially I've added in
3543 target 'all' the prerequestive 'model-pic16' so it compiled the
3544 pic16 library, but now I've commented it out for the same reasons
3546 * added targets 'model-pic16' and 'objects-pic16' to compile the
3548 * added target 'port-specific-objects-pic16' to handle the
3549 generated libraries and copy them into the build/ directory
3550 * added target 'clean-intermediate-pic16' to clean intermediate
3551 files into pic16 directory
3552 * in target 'installdirs' added line to create directory pic16 in
3553 the installation path
3555 * device/include/Makefile.in (version 1.11): in target 'install'
3556 added lines to copy all header files to installation path,
3557 * in target 'installdirs' added line create directory for pic16
3558 headers in the installation path

3573 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3574 option so that it actually works. Made it specific to the z80, since
3575 the gbz80 doesn't have these kinds of I/O ports.
3577 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3603 via literal number. The symbol is placed in the corresponding
3604 position of the data ram
3605 * (pic16_dump_section): relocatable and absolute uninitialized
3606 data are now emitted in sorted order to reduce section naming,
3607 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3608 weren't marked as being in the access bank,
3610 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3612 Added portion of GNU PIC Library under the directory
3613 device/include/pic16 and device/lib/pic16. These files

3645 all over. Telling LaTeX to be less strict with word spacing
3646 to better keep the right margin. Changed some notes about
3647 maintainance of the ports in section 3.2.1 - is it OK like this?
3649 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3689 * src/pic16/peeph.def: all peepholes with movff are commented out,
3690 because there is a problem in the pcode peep optimizer,
3691 * src/pic16/ralloc.c: the register allocator can now reuse local

3768 2004-01-07 Borut Razem <borut.razem AT siol.net>
3770 * support/scripts/sdcc.nsi: update PATH
3771 * support/scripts/sdcc.ico: craeted

3784 include information about variables allocated to the overlay
3787 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3789 * as/mcs51/lkmain.c: Help about -Y option

3801 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3803 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3804 (default behaviour).
3806 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3808 A python script to validate compiler diagnostic messages. It can be
3809 used to verify that sdcc complains about bad c source code and
3810 gives a good location of the error.
3811 * support/valdiag/Makefile,
3812 * support/valdiag/valdiag.py,
3813 * support/valdiag/tests/*
3815 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3828 * src/common.h: added ifndef/define/endif macros
3829 around the header file.
3830 Bug reported from Jesus Calvino-Fraga
3832 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3834 * sdcc.spec: updated
3835 * device/include/Makefile.in: don't install CVS directories
3836 * device/lib/Makefile.in: added removal of CVS directories after install
3837 * doc/Makefile: fixed install, added local_icons
3838 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3839 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3840 * src/ds390/gen.c (genRightShift): fixed bug #870788
3841 * src/SDCCast.c (decorateType): fixed bug #870781
3843 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3845 PIC16 port related changes:
3846 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3847 added variable stackPos,
3849 * gen.c: genCall, assignResultValue: added support for
3850 pushing/retrieving function parameters to/from stack,
3851 genFunction,genEndFunction: setup stack frame for the
3853 genAddrOf: will be changed according to bug 863624
3855 * added files genutils.c and genutils.h which contain gen*
3856 debugged and optimised functions extracted from gen.c
3858 * glue.c: added variable 'externs' which holds extern symbols,
3859 pic16emitRegularMap: is modified to properly handle relocatable
3860 symbols under the new scheme,
3861 pic16createInterruptVect: is modified
3862 pic16printPublics: is modified to emit 'global' assembler directives,
3863 added pic16_printExterns to print extern symbols,
3864 pic16glue: initializes stack/frame pointer in the beginning of
3865 the assembly output. Temporary hack, will be corrected later,
3866 because gplink yet does not support stack and SDCC does not
3867 yet support a type of crt0.o object to create the final binary.
3869 * Removed many lines that contain 8051 legacy code.
3870 * The code is finally placed under a 'code' directive.
3871 * Added port specific options.
3873 * _process_pragma: simplified since now we do not need *special*
3874 include file to define SFR registers. But a separate header
3875 will be needed. This will be developed later.
3876 * _pic16_parseOptions: added, parses port specific options:
3877 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3878 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3879 --preplace-udata-with=
3881 * _pic16_setDefaultOptions: modified to initialize section names,
3882 but hack is temporarly out of order since it needs improvement.
3883 * _pic16_genAssemblerPreamble: configuration words are emitted by
3884 their address instead of their name. This part is incomplete and
3885 supports only the 18Fxx2 devices. Other devices will emit an error
3886 during assembly since they do not contain the same set of config
3888 * _pic16_genIVT: is modified,
3890 * pcode.c: added definitions for some hardware registers that are needed
3892 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3893 All PCI entries are updated. Now LFSR is supported.
3894 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3895 * added pic16_newpCodeOpLit2 to support instructions with
3896 two literal arguments
3897 * pic16_pCode2str: corrected code that emits assembler instructions
3898 with two literal operands and those that have an access bit modifier
3899 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3900 this fixes a bug which caused some labels to be lost, when an
3901 assembler directive was added, i.e. banksel,
3902 * pic16_FixRegisterBanking: improved logic that causes the insertion
3904 * InlineFunction: functions that are called once, are not any more
3905 inlined. This can be a port option in the future,
3907 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3909 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3910 hold the corresponding uninitialized symbols,
3911 * pic16_allocProcessorRegister: registers have explicit marked the
3913 * pic16_allocInternalRegister: registers are explicit marked as
3915 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3916 processing list, so bit registers were lost,
3919 * ralloc.h: added field 'accessBank' and original symbol operand
3920 in register definition,
3921 * removed the field isMapped from register definition,
3923 ** Several functions have been removed from various sources:
3924 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3925 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3926 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3927 pic16_assignRelocatableRegisters
3929 ** others have been introduced:
3930 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3931 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3933 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3935 * support/scripts/inc2h.pl: changed definition of BIT_AT
3936 to emit 'sbit at' instead of 'bit at'. This was a request.
3938 PIC16 port related preliminary changes:
3939 * gen.c: prefixed function popRegFromString with
3940 pic16_ and all references to it corrected
3941 * pcode.c: all pic16_pc_* hardware registers prefixed
3942 with underscore (_),
3943 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3944 * ralloc.c: newReg(): when register is REG_SFR then
3945 set address to rIdx,
3946 pic16_allocProcessorRegister(): marks register wasUsed=0
3947 pic16_writeUsedRegs(): added a call to assign processor
3948 registers via pic16_assignFixedRegisters
3950 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3952 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3953 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3954 variables in unused register banks. Also the SSEG is placed
3955 wherever there is enough space for it, and IDATA can be anywhere
3956 in internal RAM. For now compile using -Wl-Y[stack_size].
3957 The mem file is different for this option as well, since it
3958 makes no sense of talking about DSEG lenght.
3960 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3962 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3963 in certain cases, e.g. when ROM assignment, patch provided
3964 from Albert den Haan.
3966 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4136 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4138 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

4209 it breaks with bitfields, extern declarations, and gcse analysis.
4210 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4211 could be assigned through a pointer, so don't complain.

4989 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4990 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4991 type for bits was changed. It resulted in bit variables becoming

5009 A few small changes that speed up the peephole optimizer.
5013 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5015 Try to make the peephole optimizer smarter by maintaining
5016 an association between the assembly source code and the
5017 iCodes that originated them. Put this information to use
5018 with a new peephole rule condition "notVolatile" so that
5019 the rules can be aggressive yet still safe.
5024 * src/mcs51/peeph.def
5026 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5030 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5031 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5032 if the left or right operand symbols have the accuse flag set.
5034 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5036 Changed the type of the result of the ! (NOT) operator to char;
5037 previously it returned the same type as the source. This allows
5038 us to eliminate all the genFloatNot functions (all of its target
5039 implementations were very buggy) since !float can use the same

5051 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5052 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5053 during interrupts. Ensure WSAVE is located at a shared bank address.
5054 2. Fixed page selection in some places
5055 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5056 the registers name strings.
5057 4. Fixed "signed / unsigned compare" compiler warnings.
5058 5. The PIC port manages its own allocation of the general purpose
5059 registers, but makes no attempt to reuse them. As a result when
5060 compiling it soon runs out of general purpose registers. Some
5061 additional code was added to the files pcode.c and device.c to walk
5062 through the function call tree and rename the registers so that they
5072 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5073 genPlus() & genMinus() when the result is the same as left or right

5079 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5081 Made bitfield a distinct type from bit so that bitfields
5082 convert as per ANSI C and bits retain their traditional
5083 boolean style behaviour. Implemented bitfield support in

5099 access to xdata mapped I/O devices.
5101 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5103 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5105 Cleaned up genPackBits and genUnpackBits and added two helper
5106 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5107 for literal assignments in genPackBits (thanks to Frieder for
5113 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5115 Fixed bug #748310 (pointer to function type mishandled when the
5116 function name is omitted). Also fixed a SIGSEGV when a function
5117 attribute (reentrant, etc) is used on a non-function or on a
5118 function but misplaced before the parameter list.

5147 Made the constant following the "interrupt" keyword optional. If
5148 omitted, the function will not automatically be given an entry
5149 in the interrupt vector table (similar to #pragma NOIV, but
5150 less syntacticly kludgy). The interrupt number is also now
5151 range checked. Also fixed a bug in the high order bit example

5172 unsigned, but are signed by default
5173 * src/SDCCval.c (constVal): rearranged
5174 * src/SDCCval.c (valMod): preliminary fix
5175 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5666 * doc/sdccman.lyx: fixed bug 739745
5667 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
5669 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5671 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5672 it can be defined with CFLAGS when running configure
5673 * src/SDCCmain.c: fixed compiling + linking with object files
5675 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5677 * configure.in: configure for pic16 port,
5678 added --disable-pic16-port
5679 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5680 * src/SDCCmain.c: linkOptions is changed to set *,
5681 added if/endif conditional macros to remove options help
5682 messages from optionsTable when a port is not configured, added
5683 support for the PIc16 port in the ports table, when executing
5684 the compiler with no port specified on command line, a default
5685 port is selected with the new macro DEFAULT_PORT which is
5686 defined in port.h, in setDefaultOptions() linkOptions is removed
5687 from initialization assignment, since now it is a set,
5688 parseCmdLine uses setParseWithComma for linkOptions, in
5689 linkEdit() linkOptions are accessed with new function indexSet()
5690 which returns the i'th item of a set variable. See SDCCset.c, in
5691 linkEdit() when calling buildCmdLine(), added linkOptions as
5692 last argument. Now users can pass arguments to gplink via the
5693 -Wl option, main() uses pic16glue() to glue up pic16 programs
5694 * src/SDCCpeeph.c: various changes to support pic16
5695 * src/SDCCset.c: added function void *indexSet(set *, int) to

5705 * src/pic16/glue.c: commented out some error producing lines
5706 * src/pic16/main.c: __config directives are commented out to stop
5707 gpasm complaining and test the linkage with gplink, _linkCmd and
5708 _asmCmd changed to be more gplink and gpasm friendly
5709 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5710 produced an error when parsed, peep rule 12 is added to utilize
5711 movff, but it is commented out since the pCode does not support
5712 yet a command with 2 address arguments
5714 2003-05-18 <johan AT balder>
5716 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5743 2003-05-11 Borut Razem <borut.razem AT siol.net>
5745 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5746 the path of bin directory, so that PATH is the only env. variable, which has to be set
5747 in case of standard installation.

6734 2003-01-07 <johan AT balder>
6736 * src/SDCCast.c (decorateType): fixed bug #600035

6751 * src/SDCCicode.c: fixed array add
6753 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6754 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6755 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6757 2003-01-04 <johan AT balder>
6759 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6761 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6762 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6764 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6765 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6771 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6772 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6774 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6775 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6777 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6779 * in \sdcc\as\mcs51\ changed these files in order to create an
6780 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6781 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6782 following files to include the previous two files: aslink.dsp,
6783 Makefile.aslink, Makefile.bcc, and Makefile.in.
6785 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6786 .adb instead of .cdb
6788 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6790 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6791 value from option --iram-size.
6793 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6795 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6798 2002-09-18 <wiml AT hhhh.org>
6800 * SDCClrange.h: exposed setFromRange() and setToRange()
6801 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6802 packRegsForAccUse() (bug 542397)
6803 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6804 multiple times and emitting the fetch operations more than once
6805 added aopGetUsesAcc() function to allow binary operators to
6806 fetch their operands in the correct order; made genMinus() emit
6807 compact code for X = LITERAL - Y
6809 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6810 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6811 sprintf() in line 1267.
6813 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6814 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6817 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6818 Changes to aslink (All the changes are marked with 'JCF'):
6820 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6823 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6824 area BSEG. Also moves, if possible, the DATA area down into the internal
6825 ram so more space is available.
6827 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6830 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6831 not bytes. Function summary() which creates a memory usage summary
6832 file with extension .mem. Reports of overlaping stack and small stack
6833 size. If the space for the stack is less than 16 bytes aslink trows a
6836 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6837 the 8051. Option 'y' for memory summary output file.
6839 Changes to sdcc (All the changes are marked with 'JCF'):
6841 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6843 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6844 overlaying area for it (uses RegBankUsed[4]).
6846 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6847 bank zero as used by default. By default aslink locates the stack
6848 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6849 the creation of the .mem file. Delegates the allocation of data area
6850 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6851 the begining of the stack area to aslink.
6853 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6854 glue() in SDCCglue.c creates an area for it.
6856 2002-09-03 Borut Razem <borut.razem AT siol.net>
6857 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6858 sdcc/src/pic/glue.c:
6859 introduced atexit() handler for teporay files removal in case of
6860 errors, assertions, ...
6862 2002-08-29 Borut Razem <borut.razem AT siol.net>
6863 * sdcc/support/cpp2/auto-host_vc_in.h:
6864 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6865 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6866 Maybe there is a similar problem with BORLANDC? It should be checked!
6868 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6869 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6870 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6871 was not executed, and the compiler (cl) launched a warning:
6872 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6874 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6875 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6877 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6878 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6880 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6881 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6882 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6883 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6884 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6885 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6886 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6887 - added Release configuration in VS projects
6888 - review of compiler an linker options
6889 - VC .exe files are generated in bin_vc directory, not to interfere
6890 with binaries generated from other projects (cygwin, mingw, bcc ...)
6892 * sdcc/src/yacc.dsp: added
6894 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6895 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6896 and insert the version number definitions from .version
6898 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6900 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6901 added - genarate auto-host.h using auto-host_vc_in.h as template
6904 removed from CVS, generated automatically
6906 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6907 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6909 2002-08-11 Borut Razem <borut.razem AT siol.net>
6910 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6912 2002-08-10 Borut Razem <borut.razem AT siol.net>
6913 * src/SDCCmain.c (main):
6914 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6915 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6916 The consequence was that some temporary files were not removed.
6919 unification of code in functions tempfilename() and tempfile():
6920 function tempnam() is defined in Visual Studio 6.0 and .NET
6922 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6924 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6925 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6926 - removed compiler command line option /WX: Treats all warnings as errors
6927 - update a list of source files, included into the project
6929 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6930 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6931 changed project type to Generic Project so that can be correcly converted to VS.NET project
6933 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6935 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6937 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6939 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6940 added return 0 statements after assert() to make compiler happy
6942 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6943 added newline in the def file to keep MSC compiler satisfied
6945 * sdcc/src/z80/gen.c:
6946 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6947 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6948 - solved MSC error in function aopDump()
6950 * sdcc_vc.h: define PREFIX as "\\sdcc"
6952 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6953 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6955 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6956 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6957 - Rewrote the register banking algorithm.
6958 - Added pCode live-range analysis to registers (for now, only non-used and
6959 singly-used registers optimized away)
6961 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6963 * 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.
6965 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6966 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6968 2002-04-22 Michael Hope <michaelh AT vroom>
6970 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
