491 Adding support for replacing ljmps with sjmps in jumptables
492 generated for switch statements. For now you need to set the
493 environment variable SDCC_SJMP_JUMPTABLE to enable this.
494 Now 4 algorithms for mcs51 jumptable generation are used:
495 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
496 addresses loaded pc-relative for up to 112 cases and stack-pushing
497 target addresses loaded with offset from dptr for up to 256 cases.

524 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
525 to call when a stack overflow occurs,
526 * (malloc.h): added CVS Id tag,
527 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
529 * added libc directory. The current version of LibC contains string
530 functions, ctype functions and macros and some functions of the
531 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
532 be extensively tested in the future. Standard disclaimer here.
533 Library is not automatically build yet. But one can build it by
534 invoking 'make' inside the libc directory.
535 * added ADC library under libio. Preliminary version yet.

545 * (pic16_storeForReturn): optimized return of 0,
546 * (genCmp): experimental code for new genCmp which uses PIC18's
547 special compare&skip instructions. Initial tests fail some times
548 with variables grater than 1 byte in size, so new code is disabled,
549 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
551 * (genCast): began a fix to optimize the casting of a bit to another
552 bit, now assigning a bitfield to another bitfield will fail, sorry,
553 * src/pic16/main.c: disabled the use of lr-support feature,
554 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

557 bits with offset (case PO_GPR_BIT),
558 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
560 * (isBankInstruction): modified to return 0 for no banking instruction,
561 and 1 for banking instruction,
562 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
563 caused stop processing pCodes after a inline assembly block,
564 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
565 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
566 registers when it shouldn't,
567 * src/pic16/ralloc.c (allocReg): add preliminary support for
568 supporting a limited set of temporary registers,
570 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
572 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
573 genDataPointerSet): ensure assignments always copy in MSB to LSB
575 (loadRegFromAop): recognize CLRH optimization,
576 (genFunction): optimize RECEIVE iCodes in reentrant functions
578 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
580 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
581 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
583 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3578 loaded with the linker search paths (-L arguments) and the libraries
3579 to be linked with the current source (-l arguments). Changes
3580 currently will affect only the pic16 port.
3581 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3582 include path the port specific paths and port specific libraries,
3583 * gplink command now contains the $3 argument,
3584 * src/pic16/device.h,
3585 * src/pic16/device.c,: structure PIC_device is made public and
3586 renamed to PIC16_device, the same for variable Pics which is renamed
3587 to Pics16. Updated all references to them.
3588 * src/pic16/glue.c (pic16glue): corrected bug with code
3589 initialization which bypassed the variable initializations block.
3591 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3592 COMPILE_FLAGS and added the --nostdinc option
3594 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3596 * device/include/mc68hc908jb8.h: Register defs for another member
3597 of the hc08 family. Contributed by Bjorn Bringert - thanks!

3601 Documenting changes from previous commits.
3602 * configure.in (version 1.56),
3603 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3604 when generating output files to configure the pic16 library,
3605 but now I've commented it out, since gputils aren't installed in the
3606 SF compile farm, so library won't compile
3608 * device/lib/Makefile.in (version 1.56): initially I've added in
3609 target 'all' the prerequestive 'model-pic16' so it compiled the
3610 pic16 library, but now I've commented it out for the same reasons
3612 * added targets 'model-pic16' and 'objects-pic16' to compile the
3614 * added target 'port-specific-objects-pic16' to handle the
3615 generated libraries and copy them into the build/ directory
3616 * added target 'clean-intermediate-pic16' to clean intermediate
3617 files into pic16 directory
3618 * in target 'installdirs' added line to create directory pic16 in
3619 the installation path
3621 * device/include/Makefile.in (version 1.11): in target 'install'
3622 added lines to copy all header files to installation path,
3623 * in target 'installdirs' added line create directory for pic16
3624 headers in the installation path

3639 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3640 option so that it actually works. Made it specific to the z80, since
3641 the gbz80 doesn't have these kinds of I/O ports.
3643 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3645 * device/include/z180.h,

3667 Mainly changes to support compilation of the device libraries
3668 * src/pic16/device.c: stack is allocated via symbol and not
3669 via literal number. The symbol is placed in the corresponding
3670 position of the data ram
3671 * (pic16_dump_section): relocatable and absolute uninitialized
3672 data are now emitted in sorted order to reduce section naming,
3673 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3674 weren't marked as being in the access bank,
3676 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3678 Added portion of GNU PIC Library under the directory
3679 device/include/pic16 and device/lib/pic16. These files
3680 contain the declarations of SFRs for the PIC18Fxx2 devices.
3681 The directory is initialized via configure from toplevel.
3683 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3685 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3686 the spilllocations to be compared correctly
3688 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3690 * src/SDCCast.c (decorateType): fixed bug introduced today
3692 2004-01-12 Borut Razem <borut.razem AT siol.net>

3710 * doc/sdccman.lyx: Moved and added some sections, small changes
3711 all over. Telling LaTeX to be less strict with word spacing
3712 to better keep the right margin. Changed some notes about
3713 maintainance of the ports in section 3.2.1 - is it OK like this?
3715 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3752 UPPER for immediate operands,
3753 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3755 * src/pic16/peeph.def: all peepholes with movff are commented out,
3756 because there is a problem in the pcode peep optimizer,
3757 * src/pic16/ralloc.c: the register allocator can now reuse local

3759 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3761 Added file src/pic16/NOTES with information about program writing on
3762 the current port version.

3794 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3797 * src/z80/main.c: added missed needLinkerScript flags (more than
3798 one port structure defined in these file)
3799 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3822 directive when no overlay data exist
3823 * (picglue): modified to emit uninitialized data segment
3824 according to udata_section_name

3834 2004-01-07 Borut Razem <borut.razem AT siol.net>
3836 * support/scripts/sdcc.nsi: update PATH
3837 * support/scripts/sdcc.ico: craeted

3850 include information about variables allocated to the overlay
3853 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3855 * as/mcs51/lkmain.c: Help about -Y option

3867 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3869 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3870 (default behaviour).
3872 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3874 A python script to validate compiler diagnostic messages. It can be
3875 used to verify that sdcc complains about bad c source code and
3876 gives a good location of the error.
3877 * support/valdiag/Makefile,
3878 * support/valdiag/valdiag.py,
3879 * support/valdiag/tests/*
3881 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3896 Bug reported from Jesus Calvino-Fraga
3898 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3900 * sdcc.spec: updated
3901 * device/include/Makefile.in: don't install CVS directories
3902 * device/lib/Makefile.in: added removal of CVS directories after install
3903 * doc/Makefile: fixed install, added local_icons
3904 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3905 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3906 * src/ds390/gen.c (genRightShift): fixed bug #870788
3907 * src/SDCCast.c (decorateType): fixed bug #870781
3909 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3911 PIC16 port related changes:
3912 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3913 added variable stackPos,
3915 * gen.c: genCall, assignResultValue: added support for
3916 pushing/retrieving function parameters to/from stack,
3917 genFunction,genEndFunction: setup stack frame for the
3919 genAddrOf: will be changed according to bug 863624
3921 * added files genutils.c and genutils.h which contain gen*
3922 debugged and optimised functions extracted from gen.c
3924 * glue.c: added variable 'externs' which holds extern symbols,
3925 pic16emitRegularMap: is modified to properly handle relocatable
3926 symbols under the new scheme,
3927 pic16createInterruptVect: is modified
3928 pic16printPublics: is modified to emit 'global' assembler directives,
3929 added pic16_printExterns to print extern symbols,
3930 pic16glue: initializes stack/frame pointer in the beginning of
3931 the assembly output. Temporary hack, will be corrected later,
3932 because gplink yet does not support stack and SDCC does not
3933 yet support a type of crt0.o object to create the final binary.
3935 * Removed many lines that contain 8051 legacy code.
3936 * The code is finally placed under a 'code' directive.
3937 * Added port specific options.
3939 * _process_pragma: simplified since now we do not need *special*
3940 include file to define SFR registers. But a separate header
3941 will be needed. This will be developed later.
3942 * _pic16_parseOptions: added, parses port specific options:
3943 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3944 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3945 --preplace-udata-with=
3947 * _pic16_setDefaultOptions: modified to initialize section names,
3948 but hack is temporarly out of order since it needs improvement.
3949 * _pic16_genAssemblerPreamble: configuration words are emitted by
3950 their address instead of their name. This part is incomplete and
3951 supports only the 18Fxx2 devices. Other devices will emit an error
3952 during assembly since they do not contain the same set of config
3954 * _pic16_genIVT: is modified,
3956 * pcode.c: added definitions for some hardware registers that are needed
3958 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3959 All PCI entries are updated. Now LFSR is supported.
3960 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3961 * added pic16_newpCodeOpLit2 to support instructions with
3962 two literal arguments
3963 * pic16_pCode2str: corrected code that emits assembler instructions
3964 with two literal operands and those that have an access bit modifier
3965 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3966 this fixes a bug which caused some labels to be lost, when an
3967 assembler directive was added, i.e. banksel,
3968 * pic16_FixRegisterBanking: improved logic that causes the insertion
3970 * InlineFunction: functions that are called once, are not any more
3971 inlined. This can be a port option in the future,
3973 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3975 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3976 hold the corresponding uninitialized symbols,
3977 * pic16_allocProcessorRegister: registers have explicit marked the
3979 * pic16_allocInternalRegister: registers are explicit marked as
3981 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3982 processing list, so bit registers were lost,
3985 * ralloc.h: added field 'accessBank' and original symbol operand
3986 in register definition,
3987 * removed the field isMapped from register definition,
3989 ** Several functions have been removed from various sources:
3990 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3991 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3992 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3993 pic16_assignRelocatableRegisters
3995 ** others have been introduced:
3996 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3997 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3999 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4001 * support/scripts/inc2h.pl: changed definition of BIT_AT
4002 to emit 'sbit at' instead of 'bit at'. This was a request.
4004 PIC16 port related preliminary changes:
4005 * gen.c: prefixed function popRegFromString with
4006 pic16_ and all references to it corrected
4007 * pcode.c: all pic16_pc_* hardware registers prefixed
4008 with underscore (_),
4009 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4010 * ralloc.c: newReg(): when register is REG_SFR then
4011 set address to rIdx,
4012 pic16_allocProcessorRegister(): marks register wasUsed=0
4013 pic16_writeUsedRegs(): added a call to assign processor
4014 registers via pic16_assignFixedRegisters
4016 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4018 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4019 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4020 variables in unused register banks. Also the SSEG is placed
4021 wherever there is enough space for it, and IDATA can be anywhere
4022 in internal RAM. For now compile using -Wl-Y[stack_size].
4023 The mem file is different for this option as well, since it
4024 makes no sense of talking about DSEG lenght.
4026 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4028 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4029 in certain cases, e.g. when ROM assignment, patch provided
4030 from Albert den Haan.
4032 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5075 A few small changes that speed up the peephole optimizer.
5079 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5081 Try to make the peephole optimizer smarter by maintaining
5082 an association between the assembly source code and the
5083 iCodes that originated them. Put this information to use
5084 with a new peephole rule condition "notVolatile" so that
5085 the rules can be aggressive yet still safe.
5090 * src/mcs51/peeph.def
5092 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5096 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5097 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5098 if the left or right operand symbols have the accuse flag set.
5100 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5102 Changed the type of the result of the ! (NOT) operator to char;
5103 previously it returned the same type as the source. This allows
5104 us to eliminate all the genFloatNot functions (all of its target
5105 implementations were very buggy) since !float can use the same
5108 * src/SDCCicode.c (ast2iCode): ! returns char

5117 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5118 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5119 during interrupts. Ensure WSAVE is located at a shared bank address.
5120 2. Fixed page selection in some places
5121 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5122 the registers name strings.
5123 4. Fixed "signed / unsigned compare" compiler warnings.
5124 5. The PIC port manages its own allocation of the general purpose
5125 registers, but makes no attempt to reuse them. As a result when
5126 compiling it soon runs out of general purpose registers. Some
5127 additional code was added to the files pcode.c and device.c to walk
5128 through the function call tree and rename the registers so that they
5138 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5139 genPlus() & genMinus() when the result is the same as left or right

5145 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5147 Made bitfield a distinct type from bit so that bitfields
5148 convert as per ANSI C and bits retain their traditional
5149 boolean style behaviour. Implemented bitfield support in
5157 * src/ds390/gen.c: bit v bitfield split
5158 * src/z80/gen.c: New support for bitfields
5159 * support/regression/tests/bitfields.c: reenabled z80,
5162 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5164 Rules 246.x, 247.x relate to bitfields, the others speed up
5165 access to xdata mapped I/O devices.
5167 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5169 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5171 Cleaned up genPackBits and genUnpackBits and added two helper
5172 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5173 for literal assignments in genPackBits (thanks to Frieder for
5179 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5181 Fixed bug #748310 (pointer to function type mishandled when the
5182 function name is omitted). Also fixed a SIGSEGV when a function
5183 attribute (reentrant, etc) is used on a non-function or on a
5184 function but misplaced before the parameter list.
5186 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5188 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5211 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5213 Made the constant following the "interrupt" keyword optional. If
5214 omitted, the function will not automatically be given an entry
5215 in the interrupt vector table (similar to #pragma NOIV, but
5216 less syntacticly kludgy). The interrupt number is also now
5217 range checked. Also fixed a bug in the high order bit example

5658 condition and ignore commands.
5660 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5662 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
5663 is in parts still quite out of date, I did changes as far as I felt makes sense
5664 for a non-native english speaker.
5665 Please feel free to add to the manual or to correct my changes.
5666 * doc/Makefile: undid touching the date of intermediate tex files.
5668 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5683 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5685 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5686 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5687 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5688 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5691 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5693 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5694 the regression tests I'm not brave enough to enable 245.b, 245.c
5695 * doc/sdccman.lyx: added latex preamble for hyperref package.
5696 Using pdflatex this will give you a hyperlinked pdf file with
5697 bookmarks. (prepend '%' before /usepackage if this breaks something)
5699 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5713 Applied patch from bug 737905 (renamed yylineo to mylineno):
5720 * src/pic16/pcode.c: Cleaned warnings
5721 * src/pic16/pcodeflow.c: Cleaned warnings

5733 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
5735 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5737 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5738 it can be defined with CFLAGS when running configure
5739 * src/SDCCmain.c: fixed compiling + linking with object files
5741 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5743 * configure.in: configure for pic16 port,
5744 added --disable-pic16-port
5745 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5746 * src/SDCCmain.c: linkOptions is changed to set *,
5747 added if/endif conditional macros to remove options help
5748 messages from optionsTable when a port is not configured, added
5749 support for the PIc16 port in the ports table, when executing
5750 the compiler with no port specified on command line, a default
5751 port is selected with the new macro DEFAULT_PORT which is
5752 defined in port.h, in setDefaultOptions() linkOptions is removed
5753 from initialization assignment, since now it is a set,
5754 parseCmdLine uses setParseWithComma for linkOptions, in
5755 linkEdit() linkOptions are accessed with new function indexSet()
5756 which returns the i'th item of a set variable. See SDCCset.c, in
5757 linkEdit() when calling buildCmdLine(), added linkOptions as
5758 last argument. Now users can pass arguments to gplink via the
5759 -Wl option, main() uses pic16glue() to glue up pic16 programs
5760 * src/SDCCpeeph.c: various changes to support pic16
5761 * src/SDCCset.c: added function void *indexSet(set *, int) to
5762 return the i'th item of the set

5767 added macro DEFAULT_PORT
5768 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
5769 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5771 * src/pic16/glue.c: commented out some error producing lines
5772 * src/pic16/main.c: __config directives are commented out to stop
5773 gpasm complaining and test the linkage with gplink, _linkCmd and
5774 _asmCmd changed to be more gplink and gpasm friendly
5775 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5776 produced an error when parsed, peep rule 12 is added to utilize
5777 movff, but it is commented out since the pCode does not support
5778 yet a command with 2 address arguments
5780 2003-05-18 <johan AT balder>
5782 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5783 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5807 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5809 2003-05-11 Borut Razem <borut.razem AT siol.net>
5811 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5812 the path of bin directory, so that PATH is the only env. variable, which has to be set
5813 in case of standard installation.
5814 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6843 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6845 * in \sdcc\as\mcs51\ changed these files in order to create an
6846 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6847 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6848 following files to include the previous two files: aslink.dsp,
6849 Makefile.aslink, Makefile.bcc, and Makefile.in.
6851 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6852 .adb instead of .cdb
6854 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6856 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6857 value from option --iram-size.
6859 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6861 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6864 2002-09-18 <wiml AT hhhh.org>
6866 * SDCClrange.h: exposed setFromRange() and setToRange()
6867 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6868 packRegsForAccUse() (bug 542397)
6869 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6870 multiple times and emitting the fetch operations more than once
6871 added aopGetUsesAcc() function to allow binary operators to
6872 fetch their operands in the correct order; made genMinus() emit
6873 compact code for X = LITERAL - Y
6875 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6876 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6877 sprintf() in line 1267.
6879 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6880 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6883 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6884 Changes to aslink (All the changes are marked with 'JCF'):
6886 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6889 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6890 area BSEG. Also moves, if possible, the DATA area down into the internal
6891 ram so more space is available.
6893 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6896 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6897 not bytes. Function summary() which creates a memory usage summary
6898 file with extension .mem. Reports of overlaping stack and small stack
6899 size. If the space for the stack is less than 16 bytes aslink trows a
6902 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6903 the 8051. Option 'y' for memory summary output file.
6905 Changes to sdcc (All the changes are marked with 'JCF'):
6907 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6909 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6910 overlaying area for it (uses RegBankUsed[4]).
6912 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6913 bank zero as used by default. By default aslink locates the stack
6914 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6915 the creation of the .mem file. Delegates the allocation of data area
6916 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6917 the begining of the stack area to aslink.
6919 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6920 glue() in SDCCglue.c creates an area for it.
6922 2002-09-03 Borut Razem <borut.razem AT siol.net>
6923 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6924 sdcc/src/pic/glue.c:
6925 introduced atexit() handler for teporay files removal in case of
6926 errors, assertions, ...
6928 2002-08-29 Borut Razem <borut.razem AT siol.net>
6929 * sdcc/support/cpp2/auto-host_vc_in.h:
6930 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6931 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6932 Maybe there is a similar problem with BORLANDC? It should be checked!
6934 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6935 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6936 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6937 was not executed, and the compiler (cl) launched a warning:
6938 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6940 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6958 * sdcc/src/yacc.dsp: added
6960 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6961 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6962 and insert the version number definitions from .version
6964 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp

6972 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6973 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6975 2002-08-11 Borut Razem <borut.razem AT siol.net>
6976 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6978 2002-08-10 Borut Razem <borut.razem AT siol.net>
6979 * src/SDCCmain.c (main):
6980 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6981 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6982 The consequence was that some temporary files were not removed.
6985 unification of code in functions tempfilename() and tempfile():
6986 function tempnam() is defined in Visual Studio 6.0 and .NET
6988 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6990 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6991 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6992 - removed compiler command line option /WX: Treats all warnings as errors
6993 - update a list of source files, included into the project
6995 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6996 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6997 changed project type to Generic Project so that can be correcly converted to VS.NET project
6999 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7001 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7005 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7006 added return 0 statements after assert() to make compiler happy
7008 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7009 added newline in the def file to keep MSC compiler satisfied
7011 * sdcc/src/z80/gen.c:
7012 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7013 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7014 - solved MSC error in function aopDump()
7016 * sdcc_vc.h: define PREFIX as "\\sdcc"
7018 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7074 were not getting allocated.
7076 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7079 Fixed left shift. Will promote the left side of a left shift
7080 if a) left shifting more than size of operand or b) when assigned
7081 to something size > size of left side
7083 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7193 * sdcc/src/SDCCloop.c:
7194 Previous fix was not good. basic blocks that have "break" or "return" are
7195 not really partof a loop , but live ranges used in these blocks should
7196 be live thru the entire loop, so set partOfLoop but don't add them to
7199 2002-02-21 <johan AT FRIJA>
