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

572 to call when a stack overflow occurs,
573 * (malloc.h): added CVS Id tag,
574 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
576 * added libc directory. The current version of LibC contains string
577 functions, ctype functions and macros and some functions of the
578 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
579 be extensively tested in the future. Standard disclaimer here.
580 Library is not automatically build yet. But one can build it by
581 invoking 'make' inside the libc directory.

594 special compare&skip instructions. Initial tests fail some times
595 with variables grater than 1 byte in size, so new code is disabled,
596 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
598 * (genCast): began a fix to optimize the casting of a bit to another
599 bit, now assigning a bitfield to another bitfield will fail, sorry,

3622 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3624 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3625 loaded with the linker search paths (-L arguments) and the libraries
3626 to be linked with the current source (-l arguments). Changes
3627 currently will affect only the pic16 port.
3628 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3629 include path the port specific paths and port specific libraries,
3630 * gplink command now contains the $3 argument,
3631 * src/pic16/device.h,
3632 * src/pic16/device.c,: structure PIC_device is made public and
3633 renamed to PIC16_device, the same for variable Pics which is renamed

3646 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3648 Documenting changes from previous commits.
3649 * configure.in (version 1.56),
3650 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3651 when generating output files to configure the pic16 library,
3652 but now I've commented it out, since gputils aren't installed in the
3653 SF compile farm, so library won't compile
3655 * device/lib/Makefile.in (version 1.56): initially I've added in
3656 target 'all' the prerequestive 'model-pic16' so it compiled the
3657 pic16 library, but now I've commented it out for the same reasons
3659 * added targets 'model-pic16' and 'objects-pic16' to compile the
3661 * added target 'port-specific-objects-pic16' to handle the
3662 generated libraries and copy them into the build/ directory
3663 * added target 'clean-intermediate-pic16' to clean intermediate
3664 files into pic16 directory
3665 * in target 'installdirs' added line to create directory pic16 in
3666 the installation path
3668 * device/include/Makefile.in (version 1.11): in target 'install'
3669 added lines to copy all header files to installation path,
3670 * in target 'installdirs' added line create directory for pic16
3671 headers in the installation path

3686 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3687 option so that it actually works. Made it specific to the z80, since
3688 the gbz80 doesn't have these kinds of I/O ports.
3690 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3692 * device/include/z180.h,

3705 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3707 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3708 changed interrupt vector table generation to only emit declared vectors.
3709 * device/include/Makefile.in: added missing backslash
3710 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3714 Mainly changes to support compilation of the device libraries
3715 * src/pic16/device.c: stack is allocated via symbol and not
3716 via literal number. The symbol is placed in the corresponding
3717 position of the data ram
3718 * (pic16_dump_section): relocatable and absolute uninitialized
3719 data are now emitted in sorted order to reduce section naming,
3720 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3721 weren't marked as being in the access bank,
3723 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3725 Added portion of GNU PIC Library under the directory
3726 device/include/pic16 and device/lib/pic16. These files
3727 contain the declarations of SFRs for the PIC18Fxx2 devices.
3728 The directory is initialized via configure from toplevel.
3730 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3732 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3733 the spilllocations to be compared correctly

3758 all over. Telling LaTeX to be less strict with word spacing
3759 to better keep the right margin. Changed some notes about
3760 maintainance of the ports in section 3.2.1 - is it OK like this?
3762 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3800 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3802 * src/pic16/peeph.def: all peepholes with movff are commented out,
3803 because there is a problem in the pcode peep optimizer,
3804 * src/pic16/ralloc.c: the register allocator can now reuse local

3914 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3916 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3917 (default behaviour).
3919 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3921 A python script to validate compiler diagnostic messages. It can be
3922 used to verify that sdcc complains about bad c source code and
3923 gives a good location of the error.
3924 * support/valdiag/Makefile,
3925 * support/valdiag/valdiag.py,
3926 * support/valdiag/tests/*

3943 Bug reported from Jesus Calvino-Fraga
3945 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3947 * sdcc.spec: updated
3948 * device/include/Makefile.in: don't install CVS directories

3956 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3958 PIC16 port related changes:
3959 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3960 added variable stackPos,
3962 * gen.c: genCall, assignResultValue: added support for
3963 pushing/retrieving function parameters to/from stack,
3964 genFunction,genEndFunction: setup stack frame for the
3966 genAddrOf: will be changed according to bug 863624
3968 * added files genutils.c and genutils.h which contain gen*
3969 debugged and optimised functions extracted from gen.c
3971 * glue.c: added variable 'externs' which holds extern symbols,
3972 pic16emitRegularMap: is modified to properly handle relocatable
3973 symbols under the new scheme,
3974 pic16createInterruptVect: is modified
3975 pic16printPublics: is modified to emit 'global' assembler directives,
3976 added pic16_printExterns to print extern symbols,
3977 pic16glue: initializes stack/frame pointer in the beginning of
3978 the assembly output. Temporary hack, will be corrected later,
3979 because gplink yet does not support stack and SDCC does not
3980 yet support a type of crt0.o object to create the final binary.
3982 * Removed many lines that contain 8051 legacy code.
3983 * The code is finally placed under a 'code' directive.
3984 * Added port specific options.
3986 * _process_pragma: simplified since now we do not need *special*
3987 include file to define SFR registers. But a separate header
3988 will be needed. This will be developed later.
3989 * _pic16_parseOptions: added, parses port specific options:
3990 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3991 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3992 --preplace-udata-with=
3994 * _pic16_setDefaultOptions: modified to initialize section names,
3995 but hack is temporarly out of order since it needs improvement.
3996 * _pic16_genAssemblerPreamble: configuration words are emitted by
3997 their address instead of their name. This part is incomplete and
3998 supports only the 18Fxx2 devices. Other devices will emit an error
3999 during assembly since they do not contain the same set of config
4001 * _pic16_genIVT: is modified,
4003 * pcode.c: added definitions for some hardware registers that are needed
4005 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4006 All PCI entries are updated. Now LFSR is supported.
4007 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4008 * added pic16_newpCodeOpLit2 to support instructions with
4009 two literal arguments
4010 * pic16_pCode2str: corrected code that emits assembler instructions
4011 with two literal operands and those that have an access bit modifier
4012 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4013 this fixes a bug which caused some labels to be lost, when an
4014 assembler directive was added, i.e. banksel,
4015 * pic16_FixRegisterBanking: improved logic that causes the insertion
4017 * InlineFunction: functions that are called once, are not any more
4018 inlined. This can be a port option in the future,
4020 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4022 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4023 hold the corresponding uninitialized symbols,
4024 * pic16_allocProcessorRegister: registers have explicit marked the
4026 * pic16_allocInternalRegister: registers are explicit marked as
4028 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4029 processing list, so bit registers were lost,
4032 * ralloc.h: added field 'accessBank' and original symbol operand
4033 in register definition,
4034 * removed the field isMapped from register definition,
4036 ** Several functions have been removed from various sources:
4037 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4038 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4039 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4040 pic16_assignRelocatableRegisters
4042 ** others have been introduced:
4043 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4044 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4046 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4048 * support/scripts/inc2h.pl: changed definition of BIT_AT
4049 to emit 'sbit at' instead of 'bit at'. This was a request.
4051 PIC16 port related preliminary changes:
4052 * gen.c: prefixed function popRegFromString with
4053 pic16_ and all references to it corrected
4054 * pcode.c: all pic16_pc_* hardware registers prefixed
4055 with underscore (_),
4056 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4057 * ralloc.c: newReg(): when register is REG_SFR then
4058 set address to rIdx,
4059 pic16_allocProcessorRegister(): marks register wasUsed=0
4060 pic16_writeUsedRegs(): added a call to assign processor
4061 registers via pic16_assignFixedRegisters
4063 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4065 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4066 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4067 variables in unused register banks. Also the SSEG is placed
4068 wherever there is enough space for it, and IDATA can be anywhere
4069 in internal RAM. For now compile using -Wl-Y[stack_size].
4070 The mem file is different for this option as well, since it
4071 makes no sense of talking about DSEG lenght.

5066 and JUMPTABLE iCodes properly now (worked by accident before)
5067 * src/mcs51/gen.c (leftRightUseAcc),
5068 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5069 iCode properly now. Use getSize instead of nRegs since a & b
5070 aren't part of the nRegs tally.
5072 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5074 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5075 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5076 before instructions that use the _STATUS register
5078 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5080 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5081 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5082 fetching of the pointer
5083 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5084 copied from genNearPointerSet()
5085 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5086 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5087 If they pop r0/r1 they must be called in the opposite order than aopOp().
5088 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5089 (resp. --stack-auto), prepared for --xstack
5091 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5095 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5097 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5098 these ports have their own __sdcc_external_start()
5100 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5102 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5103 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5104 type for bits was changed. It resulted in bit variables becoming
5105 global, which is not permitted in PIC 14 assembly output.
5107 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5109 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5111 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5113 Z80 and MCS51 linkers complaint if a public symbol is defined
5114 in more than one library module:

5120 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5122 A few small changes that speed up the peephole optimizer.
5126 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5128 Try to make the peephole optimizer smarter by maintaining
5129 an association between the assembly source code and the
5130 iCodes that originated them. Put this information to use
5131 with a new peephole rule condition "notVolatile" so that
5132 the rules can be aggressive yet still safe.
5137 * src/mcs51/peeph.def
5139 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5143 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5144 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5145 if the left or right operand symbols have the accuse flag set.
5147 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5149 Changed the type of the result of the ! (NOT) operator to char;
5150 previously it returned the same type as the source. This allows
5151 us to eliminate all the genFloatNot functions (all of its target
5152 implementations were very buggy) since !float can use the same
5155 * src/SDCCicode.c (ast2iCode): ! returns char
5156 * src/mcs51/gen.c (genNot, genNotFloat),
5157 * src/ds390/gen.c (genNot, genNotFloat),
5158 * src/z80/gen.c (genNot, genNotFloat),
5159 * src/pic/gen.c (genNot, genNotFloat),
5160 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5162 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5164 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5165 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5166 during interrupts. Ensure WSAVE is located at a shared bank address.
5167 2. Fixed page selection in some places
5168 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5169 the registers name strings.
5170 4. Fixed "signed / unsigned compare" compiler warnings.
5171 5. The PIC port manages its own allocation of the general purpose
5172 registers, but makes no attempt to reuse them. As a result when
5173 compiling it soon runs out of general purpose registers. Some
5174 additional code was added to the files pcode.c and device.c to walk
5175 through the function call tree and rename the registers so that they
5185 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5186 genPlus() & genMinus() when the result is the same as left or right

5192 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5194 Made bitfield a distinct type from bit so that bitfields
5195 convert as per ANSI C and bits retain their traditional
5196 boolean style behaviour. Implemented bitfield support in
5204 * src/ds390/gen.c: bit v bitfield split
5205 * src/z80/gen.c: New support for bitfields
5206 * support/regression/tests/bitfields.c: reenabled z80,
5209 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5211 Rules 246.x, 247.x relate to bitfields, the others speed up
5212 access to xdata mapped I/O devices.
5214 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5216 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5218 Cleaned up genPackBits and genUnpackBits and added two helper
5219 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5220 for literal assignments in genPackBits (thanks to Frieder for
5226 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5228 Fixed bug #748310 (pointer to function type mishandled when the
5229 function name is omitted). Also fixed a SIGSEGV when a function
5230 attribute (reentrant, etc) is used on a non-function or on a
5231 function but misplaced before the parameter list.
5233 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5235 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5236 * support/Util/SDCCerr.h,
5237 * support/Util/SDCCerr.c: Added func attr misuse error msg

5258 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5260 Made the constant following the "interrupt" keyword optional. If
5261 omitted, the function will not automatically be given an entry
5262 in the interrupt vector table (similar to #pragma NOIV, but
5263 less syntacticly kludgy). The interrupt number is also now
5264 range checked. Also fixed a bug in the high order bit example
5271 * support/Util/SDCCerr.c
5272 * support/Util/SDCCerr.h
5275 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5278 * src/SDCCicode.c (operandOperation): rewritten some ops
5279 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5280 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5282 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5283 be re-activated by defining REDUCE_LITERALS)
5284 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5285 unsigned, but are signed by default
5286 * src/SDCCval.c (constVal): rearranged
5287 * src/SDCCval.c (valMod): preliminary fix
5288 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5331 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5332 * src/SDCCval.c (valDiv, valMod): fixed signdness
5333 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5334 signedness of modulo, left and right shift

5740 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5741 the regression tests I'm not brave enough to enable 245.b, 245.c
5742 * doc/sdccman.lyx: added latex preamble for hyperref package.
5743 Using pdflatex this will give you a hyperlinked pdf file with
5744 bookmarks. (prepend '%' before /usepackage if this breaks something)

5760 Applied patch from bug 737905 (renamed yylineo to mylineno):
5767 * src/pic16/pcode.c: Cleaned warnings
5768 * src/pic16/pcodeflow.c: Cleaned warnings
5769 * src/pic16/pcoderegs.c: Cleaned warnings

5782 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5784 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5785 it can be defined with CFLAGS when running configure
5786 * src/SDCCmain.c: fixed compiling + linking with object files
5788 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5791 added --disable-pic16-port
5792 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5793 * src/SDCCmain.c: linkOptions is changed to set *,
5794 added if/endif conditional macros to remove options help
5795 messages from optionsTable when a port is not configured, added
5796 support for the PIc16 port in the ports table, when executing
5797 the compiler with no port specified on command line, a default
5798 port is selected with the new macro DEFAULT_PORT which is
5799 defined in port.h, in setDefaultOptions() linkOptions is removed
5800 from initialization assignment, since now it is a set,
5801 parseCmdLine uses setParseWithComma for linkOptions, in
5802 linkEdit() linkOptions are accessed with new function indexSet()
5803 which returns the i'th item of a set variable. See SDCCset.c, in
5804 linkEdit() when calling buildCmdLine(), added linkOptions as
5805 last argument. Now users can pass arguments to gplink via the
5806 -Wl option, main() uses pic16glue() to glue up pic16 programs

5818 * src/pic16/glue.c: commented out some error producing lines
5819 * src/pic16/main.c: __config directives are commented out to stop
5820 gpasm complaining and test the linkage with gplink, _linkCmd and
5821 _asmCmd changed to be more gplink and gpasm friendly
5822 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5823 produced an error when parsed, peep rule 12 is added to utilize
5824 movff, but it is commented out since the pCode does not support
5825 yet a command with 2 address arguments
5827 2003-05-18 <johan AT balder>
5829 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5830 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5854 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5856 2003-05-11 Borut Razem <borut.razem AT siol.net>
5858 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5859 the path of bin directory, so that PATH is the only env. variable, which has to be set
5860 in case of standard installation.
5861 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6890 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6892 * in \sdcc\as\mcs51\ changed these files in order to create an
6893 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6894 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6895 following files to include the previous two files: aslink.dsp,
6896 Makefile.aslink, Makefile.bcc, and Makefile.in.
6898 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6899 .adb instead of .cdb
6901 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6903 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6904 value from option --iram-size.
6906 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6908 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6911 2002-09-18 <wiml AT hhhh.org>
6913 * SDCClrange.h: exposed setFromRange() and setToRange()
6914 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6915 packRegsForAccUse() (bug 542397)
6916 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6917 multiple times and emitting the fetch operations more than once
6918 added aopGetUsesAcc() function to allow binary operators to
6919 fetch their operands in the correct order; made genMinus() emit
6920 compact code for X = LITERAL - Y
6922 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6923 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6924 sprintf() in line 1267.
6926 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6927 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6930 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6931 Changes to aslink (All the changes are marked with 'JCF'):
6933 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6936 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6937 area BSEG. Also moves, if possible, the DATA area down into the internal
6938 ram so more space is available.
6940 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6943 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6944 not bytes. Function summary() which creates a memory usage summary
6945 file with extension .mem. Reports of overlaping stack and small stack
6946 size. If the space for the stack is less than 16 bytes aslink trows a
6949 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6950 the 8051. Option 'y' for memory summary output file.
6952 Changes to sdcc (All the changes are marked with 'JCF'):
6954 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6956 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6957 overlaying area for it (uses RegBankUsed[4]).
6959 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6960 bank zero as used by default. By default aslink locates the stack
6961 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6962 the creation of the .mem file. Delegates the allocation of data area
6963 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6964 the begining of the stack area to aslink.
6966 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6967 glue() in SDCCglue.c creates an area for it.
6969 2002-09-03 Borut Razem <borut.razem AT siol.net>
6970 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6971 sdcc/src/pic/glue.c:
6972 introduced atexit() handler for teporay files removal in case of
6973 errors, assertions, ...
6975 2002-08-29 Borut Razem <borut.razem AT siol.net>
6976 * sdcc/support/cpp2/auto-host_vc_in.h:
6977 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6978 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6979 Maybe there is a similar problem with BORLANDC? It should be checked!
6981 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6982 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6983 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6984 was not executed, and the compiler (cl) launched a warning:
6985 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6987 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6995 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6996 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6997 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6998 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6999 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7000 - added Release configuration in VS projects
7001 - review of compiler an linker options
7002 - VC .exe files are generated in bin_vc directory, not to interfere
7003 with binaries generated from other projects (cygwin, mingw, bcc ...)
7005 * sdcc/src/yacc.dsp: added
7007 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7008 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7009 and insert the version number definitions from .version
7011 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7013 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7025 2002-08-10 Borut Razem <borut.razem AT siol.net>
7026 * src/SDCCmain.c (main):
7027 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7028 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7029 The consequence was that some temporary files were not removed.
7032 unification of code in functions tempfilename() and tempfile():
7033 function tempnam() is defined in Visual Studio 6.0 and .NET
7035 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7037 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7038 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

7053 added return 0 statements after assert() to make compiler happy
7055 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7056 added newline in the def file to keep MSC compiler satisfied
7058 * sdcc/src/z80/gen.c:
7059 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7060 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7061 - solved MSC error in function aopDump()
7063 * sdcc_vc.h: define PREFIX as "\\sdcc"

7121 were not getting allocated.
7123 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7126 Fixed left shift. Will promote the left side of a left shift
7127 if a) left shifting more than size of operand or b) when assigned
7128 to something size > size of left side
7130 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7240 * sdcc/src/SDCCloop.c:
7241 Previous fix was not good. basic blocks that have "break" or "return" are
7242 not really partof a loop , but live ranges used in these blocks should
7243 be live thru the entire loop, so set partOfLoop but don't add them to
7246 2002-02-21 <johan AT FRIJA>
