470 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
472 Large cummulative patch for pic16 port.
473 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
474 to call when a stack overflow occurs,
475 * (malloc.h): added CVS Id tag,
476 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
478 * added libc directory. The current version of LibC contains string
479 functions, ctype functions and macros and some functions of the
480 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
481 be extensively tested in the future. Standard disclaimer here.
482 Library is not automatically build yet. But one can build it by
483 invoking 'make' inside the libc directory.
484 * added ADC library under libio. Preliminary version yet.
486 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
487 * src/pic16/gen.c (aopForRemat): asmop size is filled by
488 aopForRemat() now and not by pic16_aopOp(),
489 * (pic16_popGetTempReg): removed warning messgae when allocating
490 temporary registers, its a buggy feature and will be removed,
491 * (pic16_popGet): set register instance field in AOP_CRY,
492 * (pic16_outBitC): fixed for results in size greater than 1,
493 * (genUminusFloat): fixed for pic16, ported code from mcs51,
494 * (pic16_storeForReturn): optimized return of 0,
495 * (genCmp): experimental code for new genCmp which uses PIC18's
496 special compare&skip instructions. Initial tests fail some times
497 with variables grater than 1 byte in size, so new code is disabled,
498 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
500 * (genCast): began a fix to optimize the casting of a bit to another
501 bit, now assigning a bitfield to another bitfield will fail, sorry,
502 * src/pic16/main.c: disabled the use of lr-support feature,
503 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
504 * added some function prototypes, added function _debugf prototype,
505 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
506 bits with offset (case PO_GPR_BIT),
507 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
509 * (isBankInstruction): modified to return 0 for no banking instruction,
510 and 1 for banking instruction,
511 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
512 caused stop processing pCodes after a inline assembly block,
513 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
514 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
515 registers when it shouldn't,
516 * src/pic16/ralloc.c (allocReg): add preliminary support for
517 supporting a limited set of temporary registers,
519 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
521 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
522 genDataPointerSet): ensure assignments always copy in MSB to LSB
524 (loadRegFromAop): recognize CLRH optimization,
525 (genFunction): optimize RECEIVE iCodes in reentrant functions
527 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
529 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
530 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
532 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
533 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be

3524 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3526 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3527 loaded with the linker search paths (-L arguments) and the libraries
3528 to be linked with the current source (-l arguments). Changes
3529 currently will affect only the pic16 port.
3530 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3531 include path the port specific paths and port specific libraries,
3532 * gplink command now contains the $3 argument,
3533 * src/pic16/device.h,
3534 * src/pic16/device.c,: structure PIC_device is made public and
3535 renamed to PIC16_device, the same for variable Pics which is renamed

3550 Documenting changes from previous commits.
3551 * configure.in (version 1.56),
3552 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3553 when generating output files to configure the pic16 library,
3554 but now I've commented it out, since gputils aren't installed in the
3555 SF compile farm, so library won't compile
3557 * device/lib/Makefile.in (version 1.56): initially I've added in
3558 target 'all' the prerequestive 'model-pic16' so it compiled the
3559 pic16 library, but now I've commented it out for the same reasons
3561 * added targets 'model-pic16' and 'objects-pic16' to compile the
3563 * added target 'port-specific-objects-pic16' to handle the
3564 generated libraries and copy them into the build/ directory
3565 * added target 'clean-intermediate-pic16' to clean intermediate
3566 files into pic16 directory
3567 * in target 'installdirs' added line to create directory pic16 in
3568 the installation path
3570 * device/include/Makefile.in (version 1.11): in target 'install'
3571 added lines to copy all header files to installation path,
3572 * in target 'installdirs' added line create directory for pic16
3573 headers in the installation path

3588 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3589 option so that it actually works. Made it specific to the z80, since
3590 the gbz80 doesn't have these kinds of I/O ports.

3618 via literal number. The symbol is placed in the corresponding
3619 position of the data ram
3620 * (pic16_dump_section): relocatable and absolute uninitialized
3621 data are now emitted in sorted order to reduce section naming,
3622 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3623 weren't marked as being in the access bank,
3625 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3627 Added portion of GNU PIC Library under the directory
3628 device/include/pic16 and device/lib/pic16. These files
3629 contain the declarations of SFRs for the PIC18Fxx2 devices.
3630 The directory is initialized via configure from toplevel.
3632 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3634 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3635 the spilllocations to be compared correctly

3660 all over. Telling LaTeX to be less strict with word spacing
3661 to better keep the right margin. Changed some notes about
3662 maintainance of the ports in section 3.2.1 - is it OK like this?
3664 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3704 * src/pic16/peeph.def: all peepholes with movff are commented out,
3705 because there is a problem in the pcode peep optimizer,
3706 * src/pic16/ralloc.c: the register allocator can now reuse local

3743 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3746 * src/z80/main.c: added missed needLinkerScript flags (more than
3747 one port structure defined in these file)
3748 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3799 include information about variables allocated to the overlay
3802 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3804 * as/mcs51/lkmain.c: Help about -Y option

3816 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3818 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3819 (default behaviour).
3821 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3823 A python script to validate compiler diagnostic messages. It can be
3824 used to verify that sdcc complains about bad c source code and
3825 gives a good location of the error.
3826 * support/valdiag/Makefile,
3827 * support/valdiag/valdiag.py,
3828 * support/valdiag/tests/*
3830 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3832 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3843 * src/common.h: added ifndef/define/endif macros
3844 around the header file.
3845 Bug reported from Jesus Calvino-Fraga
3847 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3849 * sdcc.spec: updated
3850 * device/include/Makefile.in: don't install CVS directories
3851 * device/lib/Makefile.in: added removal of CVS directories after install
3852 * doc/Makefile: fixed install, added local_icons
3853 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3854 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3855 * src/ds390/gen.c (genRightShift): fixed bug #870788
3856 * src/SDCCast.c (decorateType): fixed bug #870781
3858 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3860 PIC16 port related changes:
3861 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3862 added variable stackPos,
3864 * gen.c: genCall, assignResultValue: added support for
3865 pushing/retrieving function parameters to/from stack,
3866 genFunction,genEndFunction: setup stack frame for the
3868 genAddrOf: will be changed according to bug 863624
3870 * added files genutils.c and genutils.h which contain gen*
3871 debugged and optimised functions extracted from gen.c
3873 * glue.c: added variable 'externs' which holds extern symbols,
3874 pic16emitRegularMap: is modified to properly handle relocatable
3875 symbols under the new scheme,
3876 pic16createInterruptVect: is modified
3877 pic16printPublics: is modified to emit 'global' assembler directives,
3878 added pic16_printExterns to print extern symbols,
3879 pic16glue: initializes stack/frame pointer in the beginning of
3880 the assembly output. Temporary hack, will be corrected later,
3881 because gplink yet does not support stack and SDCC does not
3882 yet support a type of crt0.o object to create the final binary.
3884 * Removed many lines that contain 8051 legacy code.
3885 * The code is finally placed under a 'code' directive.
3886 * Added port specific options.
3888 * _process_pragma: simplified since now we do not need *special*
3889 include file to define SFR registers. But a separate header
3890 will be needed. This will be developed later.
3891 * _pic16_parseOptions: added, parses port specific options:
3892 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3893 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3894 --preplace-udata-with=
3896 * _pic16_setDefaultOptions: modified to initialize section names,
3897 but hack is temporarly out of order since it needs improvement.
3898 * _pic16_genAssemblerPreamble: configuration words are emitted by
3899 their address instead of their name. This part is incomplete and
3900 supports only the 18Fxx2 devices. Other devices will emit an error
3901 during assembly since they do not contain the same set of config
3903 * _pic16_genIVT: is modified,
3905 * pcode.c: added definitions for some hardware registers that are needed
3907 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3908 All PCI entries are updated. Now LFSR is supported.
3909 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3910 * added pic16_newpCodeOpLit2 to support instructions with
3911 two literal arguments
3912 * pic16_pCode2str: corrected code that emits assembler instructions
3913 with two literal operands and those that have an access bit modifier
3914 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3915 this fixes a bug which caused some labels to be lost, when an
3916 assembler directive was added, i.e. banksel,
3917 * pic16_FixRegisterBanking: improved logic that causes the insertion
3919 * InlineFunction: functions that are called once, are not any more
3920 inlined. This can be a port option in the future,
3922 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3924 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3925 hold the corresponding uninitialized symbols,
3926 * pic16_allocProcessorRegister: registers have explicit marked the
3928 * pic16_allocInternalRegister: registers are explicit marked as
3930 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3931 processing list, so bit registers were lost,
3934 * ralloc.h: added field 'accessBank' and original symbol operand
3935 in register definition,
3936 * removed the field isMapped from register definition,
3938 ** Several functions have been removed from various sources:
3939 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3940 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3941 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3942 pic16_assignRelocatableRegisters
3944 ** others have been introduced:
3945 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3946 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3948 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3950 * support/scripts/inc2h.pl: changed definition of BIT_AT
3951 to emit 'sbit at' instead of 'bit at'. This was a request.
3953 PIC16 port related preliminary changes:
3954 * gen.c: prefixed function popRegFromString with
3955 pic16_ and all references to it corrected
3956 * pcode.c: all pic16_pc_* hardware registers prefixed
3957 with underscore (_),
3958 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3959 * ralloc.c: newReg(): when register is REG_SFR then
3960 set address to rIdx,
3961 pic16_allocProcessorRegister(): marks register wasUsed=0
3962 pic16_writeUsedRegs(): added a call to assign processor
3963 registers via pic16_assignFixedRegisters
3965 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3967 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3968 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3969 variables in unused register banks. Also the SSEG is placed
3970 wherever there is enough space for it, and IDATA can be anywhere
3971 in internal RAM. For now compile using -Wl-Y[stack_size].
3972 The mem file is different for this option as well, since it
3973 makes no sense of talking about DSEG lenght.
3975 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3977 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3978 in certain cases, e.g. when ROM assignment, patch provided
3979 from Albert den Haan.
3981 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5004 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5005 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5024 A few small changes that speed up the peephole optimizer.
5028 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5030 Try to make the peephole optimizer smarter by maintaining
5031 an association between the assembly source code and the
5032 iCodes that originated them. Put this information to use
5033 with a new peephole rule condition "notVolatile" so that
5034 the rules can be aggressive yet still safe.
5039 * src/mcs51/peeph.def
5041 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5045 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

5047 if the left or right operand symbols have the accuse flag set.
5049 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5051 Changed the type of the result of the ! (NOT) operator to char;
5052 previously it returned the same type as the source. This allows
5053 us to eliminate all the genFloatNot functions (all of its target
5054 implementations were very buggy) since !float can use the same
5057 * src/SDCCicode.c (ast2iCode): ! returns char

5066 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5067 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5068 during interrupts. Ensure WSAVE is located at a shared bank address.
5069 2. Fixed page selection in some places
5070 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5071 the registers name strings.
5072 4. Fixed "signed / unsigned compare" compiler warnings.
5073 5. The PIC port manages its own allocation of the general purpose
5074 registers, but makes no attempt to reuse them. As a result when
5075 compiling it soon runs out of general purpose registers. Some
5076 additional code was added to the files pcode.c and device.c to walk
5077 through the function call tree and rename the registers so that they
5087 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5094 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5096 Made bitfield a distinct type from bit so that bitfields
5097 convert as per ANSI C and bits retain their traditional
5098 boolean style behaviour. Implemented bitfield support in
5106 * src/ds390/gen.c: bit v bitfield split
5107 * src/z80/gen.c: New support for bitfields
5108 * support/regression/tests/bitfields.c: reenabled z80,
5111 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5113 Rules 246.x, 247.x relate to bitfields, the others speed up
5114 access to xdata mapped I/O devices.
5116 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5118 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5120 Cleaned up genPackBits and genUnpackBits and added two helper
5121 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5122 for literal assignments in genPackBits (thanks to Frieder for
5128 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5130 Fixed bug #748310 (pointer to function type mishandled when the
5131 function name is omitted). Also fixed a SIGSEGV when a function
5132 attribute (reentrant, etc) is used on a non-function or on a
5133 function but misplaced before the parameter list.

5160 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5162 Made the constant following the "interrupt" keyword optional. If
5163 omitted, the function will not automatically be given an entry
5164 in the interrupt vector table (similar to #pragma NOIV, but
5165 less syntacticly kludgy). The interrupt number is also now
5166 range checked. Also fixed a bug in the high order bit example

5669 * src/pic16/pcode.c: Cleaned warnings
5670 * src/pic16/pcodeflow.c: Cleaned warnings
5671 * src/pic16/pcoderegs.c: Cleaned warnings
5673 2003-05-19 Scott Dattalo <scott AT dattalo.com>

5684 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5686 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5687 it can be defined with CFLAGS when running configure
5688 * src/SDCCmain.c: fixed compiling + linking with object files
5690 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5692 * configure.in: configure for pic16 port,
5693 added --disable-pic16-port
5694 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5695 * src/SDCCmain.c: linkOptions is changed to set *,
5696 added if/endif conditional macros to remove options help
5697 messages from optionsTable when a port is not configured, added
5698 support for the PIc16 port in the ports table, when executing
5699 the compiler with no port specified on command line, a default
5700 port is selected with the new macro DEFAULT_PORT which is
5701 defined in port.h, in setDefaultOptions() linkOptions is removed
5702 from initialization assignment, since now it is a set,
5703 parseCmdLine uses setParseWithComma for linkOptions, in
5704 linkEdit() linkOptions are accessed with new function indexSet()
5705 which returns the i'th item of a set variable. See SDCCset.c, in
5706 linkEdit() when calling buildCmdLine(), added linkOptions as
5707 last argument. Now users can pass arguments to gplink via the
5708 -Wl option, main() uses pic16glue() to glue up pic16 programs

5718 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5720 * src/pic16/glue.c: commented out some error producing lines
5721 * src/pic16/main.c: __config directives are commented out to stop
5722 gpasm complaining and test the linkage with gplink, _linkCmd and
5723 _asmCmd changed to be more gplink and gpasm friendly
5724 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5725 produced an error when parsed, peep rule 12 is added to utilize
5726 movff, but it is commented out since the pCode does not support
5727 yet a command with 2 address arguments
5729 2003-05-18 <johan AT balder>
5731 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5758 2003-05-11 Borut Razem <borut.razem AT siol.net>
5760 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5761 the path of bin directory, so that PATH is the only env. variable, which has to be set

6749 2003-01-07 <johan AT balder>
6751 * src/SDCCast.c (decorateType): fixed bug #600035

6766 * src/SDCCicode.c: fixed array add
6768 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6769 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6770 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6772 2003-01-04 <johan AT balder>
6774 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6776 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6777 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6779 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6780 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6789 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6790 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6792 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6794 * in \sdcc\as\mcs51\ changed these files in order to create an
6795 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6796 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6797 following files to include the previous two files: aslink.dsp,
6798 Makefile.aslink, Makefile.bcc, and Makefile.in.
6800 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6801 .adb instead of .cdb
6803 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6805 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6806 value from option --iram-size.
6808 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6810 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6813 2002-09-18 <wiml AT hhhh.org>
6815 * SDCClrange.h: exposed setFromRange() and setToRange()
6816 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6817 packRegsForAccUse() (bug 542397)
6818 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6819 multiple times and emitting the fetch operations more than once
6820 added aopGetUsesAcc() function to allow binary operators to
6821 fetch their operands in the correct order; made genMinus() emit
6822 compact code for X = LITERAL - Y
6824 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6825 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6826 sprintf() in line 1267.
6828 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6829 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6832 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6833 Changes to aslink (All the changes are marked with 'JCF'):
6835 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6838 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6839 area BSEG. Also moves, if possible, the DATA area down into the internal
6840 ram so more space is available.
6842 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6845 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6846 not bytes. Function summary() which creates a memory usage summary
6847 file with extension .mem. Reports of overlaping stack and small stack
6848 size. If the space for the stack is less than 16 bytes aslink trows a
6851 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6852 the 8051. Option 'y' for memory summary output file.
6854 Changes to sdcc (All the changes are marked with 'JCF'):
6856 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6858 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6859 overlaying area for it (uses RegBankUsed[4]).
6861 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6862 bank zero as used by default. By default aslink locates the stack
6863 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6864 the creation of the .mem file. Delegates the allocation of data area
6865 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6866 the begining of the stack area to aslink.
6868 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6869 glue() in SDCCglue.c creates an area for it.
6871 2002-09-03 Borut Razem <borut.razem AT siol.net>
6872 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6873 sdcc/src/pic/glue.c:
6874 introduced atexit() handler for teporay files removal in case of
6875 errors, assertions, ...
6877 2002-08-29 Borut Razem <borut.razem AT siol.net>
6878 * sdcc/support/cpp2/auto-host_vc_in.h:
6879 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6880 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6881 Maybe there is a similar problem with BORLANDC? It should be checked!
6883 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6884 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6885 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6886 was not executed, and the compiler (cl) launched a warning:
6887 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6889 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6890 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6892 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6893 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6895 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6896 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6897 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6898 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6899 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6900 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6901 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6902 - added Release configuration in VS projects
6903 - review of compiler an linker options
6904 - VC .exe files are generated in bin_vc directory, not to interfere
6905 with binaries generated from other projects (cygwin, mingw, bcc ...)
6907 * sdcc/src/yacc.dsp: added
6909 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6910 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6911 and insert the version number definitions from .version
6913 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6915 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6916 added - genarate auto-host.h using auto-host_vc_in.h as template
6919 removed from CVS, generated automatically
6921 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6922 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6924 2002-08-11 Borut Razem <borut.razem AT siol.net>
6925 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6927 2002-08-10 Borut Razem <borut.razem AT siol.net>
6928 * src/SDCCmain.c (main):
6929 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6930 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6931 The consequence was that some temporary files were not removed.
6934 unification of code in functions tempfilename() and tempfile():
6935 function tempnam() is defined in Visual Studio 6.0 and .NET
6937 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6939 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6940 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6941 - removed compiler command line option /WX: Treats all warnings as errors
6942 - update a list of source files, included into the project
6944 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6945 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6946 changed project type to Generic Project so that can be correcly converted to VS.NET project
6948 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6950 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6952 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6954 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6955 added return 0 statements after assert() to make compiler happy
6957 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6958 added newline in the def file to keep MSC compiler satisfied
6960 * sdcc/src/z80/gen.c:
6961 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6962 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6963 - solved MSC error in function aopDump()
