560 Adding support for replacing ljmps with sjmps in jumptables
561 generated for switch statements. For now you need to set the
562 environment variable SDCC_SJMP_JUMPTABLE to enable this.
563 Now 4 algorithms for mcs51 jumptable generation are used:
564 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
565 addresses loaded pc-relative for up to 112 cases and stack-pushing
566 target addresses loaded with offset from dptr for up to 256 cases.

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

614 * (pic16_storeForReturn): optimized return of 0,
615 * (genCmp): experimental code for new genCmp which uses PIC18's
616 special compare&skip instructions. Initial tests fail some times
617 with variables grater than 1 byte in size, so new code is disabled,
618 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
620 * (genCast): began a fix to optimize the casting of a bit to another
621 bit, now assigning a bitfield to another bitfield will fail, sorry,

3572 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3573 * src/SDCCsymt.c (computeType),
3574 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3575 must not cause an unsigned operation
3576 * src/pic/glue (pic14emitRegularMap),
3577 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3579 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
3581 * src/pic/pcode.c (PCodeID): commented out left over debug code
3583 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
3585 * support/valdiag/tests/overflow.c: added shift tests
3593 * src/pic/pcodepeep.c,
3594 * src/pic/pcoderegs.c,
3596 * src/pic/ralloc.h: applied patch from Slade Rich;
3597 added support for multiple code pages and multiple RAM banks on the
3598 PIC 14 port. The ASM files now no longer simply assume all the
3599 code / RAM are in the same page / bank. This means the linker can
3600 safely allocate code/RAM of separate ASM files to different pages/banks.
3601 * doc/sdccman.lyx: added Slade's tips
3602 * src/mcs51/peeph.def: fixed bug #880768

3611 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3614 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3615 strtof is not part of C89 and isn't included with Mac OS X.
3617 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3619 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3641 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
3644 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3646 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3647 loaded with the linker search paths (-L arguments) and the libraries
3648 to be linked with the current source (-l arguments). Changes
3649 currently will affect only the pic16 port.
3650 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3651 include path the port specific paths and port specific libraries,
3652 * gplink command now contains the $3 argument,
3653 * src/pic16/device.h,
3654 * src/pic16/device.c,: structure PIC_device is made public and
3655 renamed to PIC16_device, the same for variable Pics which is renamed
3656 to Pics16. Updated all references to them.

3670 Documenting changes from previous commits.
3671 * configure.in (version 1.56),
3672 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3673 when generating output files to configure the pic16 library,
3674 but now I've commented it out, since gputils aren't installed in the
3675 SF compile farm, so library won't compile
3677 * device/lib/Makefile.in (version 1.56): initially I've added in
3678 target 'all' the prerequestive 'model-pic16' so it compiled the
3679 pic16 library, but now I've commented it out for the same reasons
3681 * added targets 'model-pic16' and 'objects-pic16' to compile the
3683 * added target 'port-specific-objects-pic16' to handle the
3684 generated libraries and copy them into the build/ directory
3685 * added target 'clean-intermediate-pic16' to clean intermediate
3686 files into pic16 directory
3687 * in target 'installdirs' added line to create directory pic16 in
3688 the installation path
3690 * device/include/Makefile.in (version 1.11): in target 'install'
3691 added lines to copy all header files to installation path,
3692 * in target 'installdirs' added line create directory for pic16
3693 headers in the installation path

3708 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3709 option so that it actually works. Made it specific to the z80, since
3710 the gbz80 doesn't have these kinds of I/O ports.
3712 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3714 * device/include/z180.h,

3736 Mainly changes to support compilation of the device libraries
3737 * src/pic16/device.c: stack is allocated via symbol and not
3738 via literal number. The symbol is placed in the corresponding
3739 position of the data ram
3740 * (pic16_dump_section): relocatable and absolute uninitialized
3741 data are now emitted in sorted order to reduce section naming,
3742 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3743 weren't marked as being in the access bank,
3745 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3747 Added portion of GNU PIC Library under the directory
3748 device/include/pic16 and device/lib/pic16. These files
3749 contain the declarations of SFRs for the PIC18Fxx2 devices.
3750 The directory is initialized via configure from toplevel.
3752 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3754 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3780 all over. Telling LaTeX to be less strict with word spacing
3781 to better keep the right margin. Changed some notes about
3782 maintainance of the ports in section 3.2.1 - is it OK like this?
3784 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3822 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3824 * src/pic16/peeph.def: all peepholes with movff are commented out,
3825 because there is a problem in the pcode peep optimizer,
3826 * src/pic16/ralloc.c: the register allocator can now reuse local

3978 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3980 PIC16 port related changes:
3981 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3982 added variable stackPos,
3984 * gen.c: genCall, assignResultValue: added support for
3985 pushing/retrieving function parameters to/from stack,
3986 genFunction,genEndFunction: setup stack frame for the
3988 genAddrOf: will be changed according to bug 863624
3990 * added files genutils.c and genutils.h which contain gen*
3991 debugged and optimised functions extracted from gen.c
3993 * glue.c: added variable 'externs' which holds extern symbols,
3994 pic16emitRegularMap: is modified to properly handle relocatable
3995 symbols under the new scheme,
3996 pic16createInterruptVect: is modified
3997 pic16printPublics: is modified to emit 'global' assembler directives,
3998 added pic16_printExterns to print extern symbols,
3999 pic16glue: initializes stack/frame pointer in the beginning of
4000 the assembly output. Temporary hack, will be corrected later,
4001 because gplink yet does not support stack and SDCC does not
4002 yet support a type of crt0.o object to create the final binary.
4004 * Removed many lines that contain 8051 legacy code.
4005 * The code is finally placed under a 'code' directive.
4006 * Added port specific options.
4008 * _process_pragma: simplified since now we do not need *special*
4009 include file to define SFR registers. But a separate header
4010 will be needed. This will be developed later.
4011 * _pic16_parseOptions: added, parses port specific options:
4012 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4013 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4014 --preplace-udata-with=
4016 * _pic16_setDefaultOptions: modified to initialize section names,
4017 but hack is temporarly out of order since it needs improvement.
4018 * _pic16_genAssemblerPreamble: configuration words are emitted by
4019 their address instead of their name. This part is incomplete and
4020 supports only the 18Fxx2 devices. Other devices will emit an error
4021 during assembly since they do not contain the same set of config
4023 * _pic16_genIVT: is modified,
4025 * pcode.c: added definitions for some hardware registers that are needed
4027 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4028 All PCI entries are updated. Now LFSR is supported.
4029 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4030 * added pic16_newpCodeOpLit2 to support instructions with
4031 two literal arguments
4032 * pic16_pCode2str: corrected code that emits assembler instructions
4033 with two literal operands and those that have an access bit modifier
4034 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4035 this fixes a bug which caused some labels to be lost, when an
4036 assembler directive was added, i.e. banksel,
4037 * pic16_FixRegisterBanking: improved logic that causes the insertion
4039 * InlineFunction: functions that are called once, are not any more
4040 inlined. This can be a port option in the future,
4042 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4044 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4045 hold the corresponding uninitialized symbols,
4046 * pic16_allocProcessorRegister: registers have explicit marked the
4048 * pic16_allocInternalRegister: registers are explicit marked as
4050 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4051 processing list, so bit registers were lost,
4054 * ralloc.h: added field 'accessBank' and original symbol operand
4055 in register definition,
4056 * removed the field isMapped from register definition,
4058 ** Several functions have been removed from various sources:
4059 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4060 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4061 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4062 pic16_assignRelocatableRegisters
4064 ** others have been introduced:
4065 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection

4070 * support/scripts/inc2h.pl: changed definition of BIT_AT
4071 to emit 'sbit at' instead of 'bit at'. This was a request.
4073 PIC16 port related preliminary changes:
4074 * gen.c: prefixed function popRegFromString with
4075 pic16_ and all references to it corrected
4076 * pcode.c: all pic16_pc_* hardware registers prefixed
4077 with underscore (_),
4078 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4079 * ralloc.c: newReg(): when register is REG_SFR then
4080 set address to rIdx,
4081 pic16_allocProcessorRegister(): marks register wasUsed=0
4082 pic16_writeUsedRegs(): added a call to assign processor
4083 registers via pic16_assignFixedRegisters
4085 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4087 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4088 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4089 variables in unused register banks. Also the SSEG is placed
4090 wherever there is enough space for it, and IDATA can be anywhere
4091 in internal RAM. For now compile using -Wl-Y[stack_size].
4092 The mem file is different for this option as well, since it
4093 makes no sense of talking about DSEG lenght.
4095 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4097 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4098 in certain cases, e.g. when ROM assignment, patch provided
4099 from Albert den Haan.

4344 it breaks with bitfields, extern declarations, and gcse analysis.
4345 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4346 could be assigned through a pointer, so don't complain.

5090 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5091 iCode properly now. Use getSize instead of nRegs since a & b
5092 aren't part of the nRegs tally.
5094 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5096 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5102 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5103 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5104 fetching of the pointer
5105 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5106 copied from genNearPointerSet()
5107 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5108 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5109 If they pop r0/r1 they must be called in the opposite order than aopOp().
5110 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5111 (resp. --stack-auto), prepared for --xstack

5122 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5124 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5125 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5126 type for bits was changed. It resulted in bit variables becoming
5127 global, which is not permitted in PIC 14 assembly output.
5129 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5131 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5144 A few small changes that speed up the peephole optimizer.
5148 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5150 Try to make the peephole optimizer smarter by maintaining
5151 an association between the assembly source code and the
5152 iCodes that originated them. Put this information to use
5153 with a new peephole rule condition "notVolatile" so that
5154 the rules can be aggressive yet still safe.
5159 * src/mcs51/peeph.def
5161 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5165 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5166 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5167 if the left or right operand symbols have the accuse flag set.
5169 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5171 Changed the type of the result of the ! (NOT) operator to char;
5172 previously it returned the same type as the source. This allows
5173 us to eliminate all the genFloatNot functions (all of its target
5174 implementations were very buggy) since !float can use the same
5177 * src/SDCCicode.c (ast2iCode): ! returns char

5186 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5187 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5188 during interrupts. Ensure WSAVE is located at a shared bank address.
5189 2. Fixed page selection in some places
5190 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5191 the registers name strings.
5192 4. Fixed "signed / unsigned compare" compiler warnings.
5193 5. The PIC port manages its own allocation of the general purpose
5194 registers, but makes no attempt to reuse them. As a result when
5195 compiling it soon runs out of general purpose registers. Some
5196 additional code was added to the files pcode.c and device.c to walk
5197 through the function call tree and rename the registers so that they
5207 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5208 genPlus() & genMinus() when the result is the same as left or right

5214 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5216 Made bitfield a distinct type from bit so that bitfields
5217 convert as per ANSI C and bits retain their traditional
5218 boolean style behaviour. Implemented bitfield support in
5226 * src/ds390/gen.c: bit v bitfield split
5227 * src/z80/gen.c: New support for bitfields
5228 * support/regression/tests/bitfields.c: reenabled z80,
5231 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5233 Rules 246.x, 247.x relate to bitfields, the others speed up
5234 access to xdata mapped I/O devices.
5236 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5238 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5240 Cleaned up genPackBits and genUnpackBits and added two helper
5241 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5242 for literal assignments in genPackBits (thanks to Frieder for
5248 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5250 Fixed bug #748310 (pointer to function type mishandled when the
5251 function name is omitted). Also fixed a SIGSEGV when a function
5252 attribute (reentrant, etc) is used on a non-function or on a
5253 function but misplaced before the parameter list.
5255 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5257 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5280 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5282 Made the constant following the "interrupt" keyword optional. If
5283 omitted, the function will not automatically be given an entry
5284 in the interrupt vector table (similar to #pragma NOIV, but
5285 less syntacticly kludgy). The interrupt number is also now
5286 range checked. Also fixed a bug in the high order bit example

5300 * src/SDCCicode.c (operandOperation): rewritten some ops
5301 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5302 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5304 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5305 be re-activated by defining REDUCE_LITERALS)
5306 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5307 unsigned, but are signed by default
5308 * src/SDCCval.c (constVal): rearranged
5309 * src/SDCCval.c (valMod): preliminary fix
5310 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5762 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5763 the regression tests I'm not brave enough to enable 245.b, 245.c
5764 * doc/sdccman.lyx: added latex preamble for hyperref package.
5765 Using pdflatex this will give you a hyperlinked pdf file with
5766 bookmarks. (prepend '%' before /usepackage if this breaks something)

5782 Applied patch from bug 737905 (renamed yylineo to mylineno):
5789 * src/pic16/pcode.c: Cleaned warnings
5790 * src/pic16/pcodeflow.c: Cleaned warnings
5791 * src/pic16/pcoderegs.c: Cleaned warnings

5804 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5806 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5807 it can be defined with CFLAGS when running configure
5808 * src/SDCCmain.c: fixed compiling + linking with object files
5810 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5813 added --disable-pic16-port
5814 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5815 * src/SDCCmain.c: linkOptions is changed to set *,
5816 added if/endif conditional macros to remove options help
5817 messages from optionsTable when a port is not configured, added
5818 support for the PIc16 port in the ports table, when executing
5819 the compiler with no port specified on command line, a default
5820 port is selected with the new macro DEFAULT_PORT which is
5821 defined in port.h, in setDefaultOptions() linkOptions is removed
5822 from initialization assignment, since now it is a set,
5823 parseCmdLine uses setParseWithComma for linkOptions, in
5824 linkEdit() linkOptions are accessed with new function indexSet()
5825 which returns the i'th item of a set variable. See SDCCset.c, in
5826 linkEdit() when calling buildCmdLine(), added linkOptions as
5827 last argument. Now users can pass arguments to gplink via the
5828 -Wl option, main() uses pic16glue() to glue up pic16 programs

5840 * src/pic16/glue.c: commented out some error producing lines
5841 * src/pic16/main.c: __config directives are commented out to stop
5842 gpasm complaining and test the linkage with gplink, _linkCmd and
5843 _asmCmd changed to be more gplink and gpasm friendly
5844 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5845 produced an error when parsed, peep rule 12 is added to utilize
5846 movff, but it is commented out since the pCode does not support
5847 yet a command with 2 address arguments
5849 2003-05-18 <johan AT balder>
5851 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5852 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5878 2003-05-11 Borut Razem <borut.razem AT siol.net>
5880 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5881 the path of bin directory, so that PATH is the only env. variable, which has to be set
5882 in case of standard installation.
5883 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6955 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6958 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6959 area BSEG. Also moves, if possible, the DATA area down into the internal
6960 ram so more space is available.
6962 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6965 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6966 not bytes. Function summary() which creates a memory usage summary
6967 file with extension .mem. Reports of overlaping stack and small stack
6968 size. If the space for the stack is less than 16 bytes aslink trows a
6971 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6972 the 8051. Option 'y' for memory summary output file.
6974 Changes to sdcc (All the changes are marked with 'JCF'):
6976 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].

6979 overlaying area for it (uses RegBankUsed[4]).
6981 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6982 bank zero as used by default. By default aslink locates the stack
6983 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6984 the creation of the .mem file. Delegates the allocation of data area
6985 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6986 the begining of the stack area to aslink.
6988 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6989 glue() in SDCCglue.c creates an area for it.
6991 2002-09-03 Borut Razem <borut.razem AT siol.net>
6992 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6993 sdcc/src/pic/glue.c:
6994 introduced atexit() handler for teporay files removal in case of
6995 errors, assertions, ...
6997 2002-08-29 Borut Razem <borut.razem AT siol.net>
6998 * sdcc/support/cpp2/auto-host_vc_in.h:
6999 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7000 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7001 Maybe there is a similar problem with BORLANDC? It should be checked!
7003 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7004 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7005 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7006 was not executed, and the compiler (cl) launched a warning:
7007 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7009 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7010 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7012 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7013 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7015 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7016 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7017 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7018 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7019 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7020 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7021 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7022 - added Release configuration in VS projects
7023 - review of compiler an linker options
7024 - VC .exe files are generated in bin_vc directory, not to interfere
7025 with binaries generated from other projects (cygwin, mingw, bcc ...)
7027 * sdcc/src/yacc.dsp: added
7029 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7030 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7031 and insert the version number definitions from .version
7033 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7035 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7036 added - genarate auto-host.h using auto-host_vc_in.h as template
7039 removed from CVS, generated automatically
7041 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>

7044 2002-08-11 Borut Razem <borut.razem AT siol.net>
7045 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7047 2002-08-10 Borut Razem <borut.razem AT siol.net>
7048 * src/SDCCmain.c (main):
7049 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7050 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7051 The consequence was that some temporary files were not removed.
7054 unification of code in functions tempfilename() and tempfile():
7055 function tempnam() is defined in Visual Studio 6.0 and .NET
7057 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7059 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7060 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7061 - removed compiler command line option /WX: Treats all warnings as errors
7062 - update a list of source files, included into the project
7064 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7065 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7066 changed project type to Generic Project so that can be correcly converted to VS.NET project
7068 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7070 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7072 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7074 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7075 added return 0 statements after assert() to make compiler happy
7077 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7078 added newline in the def file to keep MSC compiler satisfied
7080 * sdcc/src/z80/gen.c:
7081 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7082 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7083 - solved MSC error in function aopDump()
7085 * sdcc_vc.h: define PREFIX as "\\sdcc"
7087 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7088 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7136 Added -p option. Allows port dependent processor to be specified.
7139 Initialized the new field char *Processor field to NULL in all ports
7142 Compiler generated registers for interrupt context saving
7143 were not getting allocated.
7145 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7148 Fixed left shift. Will promote the left side of a left shift
7149 if a) left shifting more than size of operand or b) when assigned
7150 to something size > size of left side
7152 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7260 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7262 * sdcc/src/SDCCloop.c:
7263 Previous fix was not good. basic blocks that have "break" or "return" are
7264 not really partof a loop , but live ranges used in these blocks should
7265 be live thru the entire loop, so set partOfLoop but don't add them to
7268 2002-02-21 <johan AT FRIJA>
7270 * src/SDCCcse.c: fixed bug #514308
7272 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7278 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7280 2002-02-10 Karl Bongers <karl AT turbobit.com>
7283 Fixed up SDCDB debugger somewhat. Updated debugger/README
7284 with lots of comments and notes.
7286 * device/examples/test2.c:
