200 functions, ctype functions and macros and some functions of the
201 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
202 be extensively tested in the future. Standard disclaimer here.

219 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
221 * (genCast): began a fix to optimize the casting of a bit to another
222 bit, now assigning a bitfield to another bitfield will fail, sorry,

3136 * src/SDCCast.c (addCast): added promotion to int
3137 (decorateType): updated call to upCast()
3138 * src/SDCCicode.c (geniCodeLeftShift): removed call to
3139 usualUnaryConversions()
3141 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
3143 * support/regression/tests/literalop.c (mulWrapper): Added a
3144 wrapper to remove integer overflow warnings.

3148 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
3151 * support/regression/generate-cases.py (main): Changed from inline
3154 * doc/Makefile (install): Changed to depth first to get rid of
3155 missing directory install warning.
3157 * as/Makefile (install-doc): Made work on Mac.
3159 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3161 * src/SDCCast.c: added an additional type flow in decorateType() of
3162 opposite direction, see feature request #860006; it's enabled at runtime
3163 by setting the environment variable SDCC_NEWTYPEFLOW
3164 * src/SDCCast.h: changed prototype of decorateType()
3165 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3166 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3167 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3168 see feature request #877103
3169 * src/SDCCval.c: updated call of decorateType()
3170 (valBitwise): fixed bug #882876
3171 (valMinus): added promotion
3172 (valLogicAndOr): result is unsigned
3173 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3174 * src/SDCCsymt.c (computeType),
3175 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3176 must not cause an unsigned operation

3197 * src/pic/ralloc.h: applied patch from Slade Rich;
3198 added support for multiple code pages and multiple RAM banks on the
3199 PIC 14 port. The ASM files now no longer simply assume all the
3200 code / RAM are in the same page / bank. This means the linker can
3201 safely allocate code/RAM of separate ASM files to different pages/banks.
3202 * doc/sdccman.lyx: added Slade's tips
3203 * src/mcs51/peeph.def: fixed bug #880768

3215 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3216 strtof is not part of C89 and isn't included with Mac OS X.
3218 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3220 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3245 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3247 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3248 loaded with the linker search paths (-L arguments) and the libraries
3249 to be linked with the current source (-l arguments). Changes
3250 currently will affect only the pic16 port.
3251 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3252 include path the port specific paths and port specific libraries,
3253 * gplink command now contains the $3 argument,
3254 * src/pic16/device.h,
3255 * src/pic16/device.c,: structure PIC_device is made public and
3256 renamed to PIC16_device, the same for variable Pics which is renamed

3271 Documenting changes from previous commits.
3272 * configure.in (version 1.56),
3273 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3274 when generating output files to configure the pic16 library,
3275 but now I've commented it out, since gputils aren't installed in the
3276 SF compile farm, so library won't compile
3278 * device/lib/Makefile.in (version 1.56): initially I've added in
3279 target 'all' the prerequestive 'model-pic16' so it compiled the
3280 pic16 library, but now I've commented it out for the same reasons
3282 * added targets 'model-pic16' and 'objects-pic16' to compile the
3284 * added target 'port-specific-objects-pic16' to handle the
3285 generated libraries and copy them into the build/ directory
3286 * added target 'clean-intermediate-pic16' to clean intermediate
3287 files into pic16 directory
3288 * in target 'installdirs' added line to create directory pic16 in
3289 the installation path

3292 added lines to copy all header files to installation path,
3293 * in target 'installdirs' added line create directory for pic16
3294 headers in the installation path

3309 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3310 option so that it actually works. Made it specific to the z80, since
3311 the gbz80 doesn't have these kinds of I/O ports.
3313 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3315 * device/include/z180.h,

3339 via literal number. The symbol is placed in the corresponding
3340 position of the data ram
3341 * (pic16_dump_section): relocatable and absolute uninitialized
3342 data are now emitted in sorted order to reduce section naming,
3343 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3344 weren't marked as being in the access bank,
3346 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3348 Added portion of GNU PIC Library under the directory
3349 device/include/pic16 and device/lib/pic16. These files
3350 contain the declarations of SFRs for the PIC18Fxx2 devices.
3351 The directory is initialized via configure from toplevel.

3381 all over. Telling LaTeX to be less strict with word spacing
3382 to better keep the right margin. Changed some notes about
3383 maintainance of the ports in section 3.2.1 - is it OK like this?
3385 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3425 * src/pic16/peeph.def: all peepholes with movff are commented out,
3426 because there is a problem in the pcode peep optimizer,
3427 * src/pic16/ralloc.c: the register allocator can now reuse local

3566 Bug reported from Jesus Calvino-Fraga
3568 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3570 * sdcc.spec: updated
3571 * device/include/Makefile.in: don't install CVS directories

3579 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3581 PIC16 port related changes:
3582 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3583 added variable stackPos,
3585 * gen.c: genCall, assignResultValue: added support for
3586 pushing/retrieving function parameters to/from stack,
3587 genFunction,genEndFunction: setup stack frame for the
3589 genAddrOf: will be changed according to bug 863624
3591 * added files genutils.c and genutils.h which contain gen*
3592 debugged and optimised functions extracted from gen.c
3594 * glue.c: added variable 'externs' which holds extern symbols,
3595 pic16emitRegularMap: is modified to properly handle relocatable
3596 symbols under the new scheme,
3597 pic16createInterruptVect: is modified
3598 pic16printPublics: is modified to emit 'global' assembler directives,
3599 added pic16_printExterns to print extern symbols,
3600 pic16glue: initializes stack/frame pointer in the beginning of
3601 the assembly output. Temporary hack, will be corrected later,
3602 because gplink yet does not support stack and SDCC does not
3603 yet support a type of crt0.o object to create the final binary.
3605 * Removed many lines that contain 8051 legacy code.
3606 * The code is finally placed under a 'code' directive.
3607 * Added port specific options.
3609 * _process_pragma: simplified since now we do not need *special*
3610 include file to define SFR registers. But a separate header
3611 will be needed. This will be developed later.
3612 * _pic16_parseOptions: added, parses port specific options:
3613 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3614 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3615 --preplace-udata-with=
3617 * _pic16_setDefaultOptions: modified to initialize section names,
3618 but hack is temporarly out of order since it needs improvement.
3619 * _pic16_genAssemblerPreamble: configuration words are emitted by
3620 their address instead of their name. This part is incomplete and
3621 supports only the 18Fxx2 devices. Other devices will emit an error
3622 during assembly since they do not contain the same set of config
3624 * _pic16_genIVT: is modified,
3626 * pcode.c: added definitions for some hardware registers that are needed
3628 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3629 All PCI entries are updated. Now LFSR is supported.
3630 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3631 * added pic16_newpCodeOpLit2 to support instructions with
3632 two literal arguments
3633 * pic16_pCode2str: corrected code that emits assembler instructions
3634 with two literal operands and those that have an access bit modifier
3635 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3636 this fixes a bug which caused some labels to be lost, when an
3637 assembler directive was added, i.e. banksel,
3638 * pic16_FixRegisterBanking: improved logic that causes the insertion
3640 * InlineFunction: functions that are called once, are not any more
3641 inlined. This can be a port option in the future,
3643 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3645 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3646 hold the corresponding uninitialized symbols,
3647 * pic16_allocProcessorRegister: registers have explicit marked the
3649 * pic16_allocInternalRegister: registers are explicit marked as
3651 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3652 processing list, so bit registers were lost,
3655 * ralloc.h: added field 'accessBank' and original symbol operand
3656 in register definition,
3657 * removed the field isMapped from register definition,
3659 ** Several functions have been removed from various sources:
3660 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3661 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3662 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3663 pic16_assignRelocatableRegisters
3665 ** others have been introduced:
3666 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3667 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3669 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3671 * support/scripts/inc2h.pl: changed definition of BIT_AT
3672 to emit 'sbit at' instead of 'bit at'. This was a request.
3674 PIC16 port related preliminary changes:
3675 * gen.c: prefixed function popRegFromString with
3676 pic16_ and all references to it corrected
3677 * pcode.c: all pic16_pc_* hardware registers prefixed
3678 with underscore (_),
3679 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3680 * ralloc.c: newReg(): when register is REG_SFR then
3681 set address to rIdx,
3682 pic16_allocProcessorRegister(): marks register wasUsed=0
3683 pic16_writeUsedRegs(): added a call to assign processor
3684 registers via pic16_assignFixedRegisters
3686 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3688 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3689 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3690 variables in unused register banks. Also the SSEG is placed
3691 wherever there is enough space for it, and IDATA can be anywhere
3692 in internal RAM. For now compile using -Wl-Y[stack_size].
3693 The mem file is different for this option as well, since it
3694 makes no sense of talking about DSEG lenght.
3696 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3698 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3699 in certain cases, e.g. when ROM assignment, patch provided
3700 from Albert den Haan.

3943 * src/SDCCast.c (decorateType): disabled a transformation I added in
3944 revision 1.188 (access to fields of a structure at an absolute address);
3945 it breaks with bitfields, extern declarations, and gcse analysis.
3946 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3947 could be assigned through a pointer, so don't complain.

4055 xdata initialization slightly shorter
4057 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4706 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4707 copied from genNearPointerSet()
4708 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4709 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4725 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4726 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4727 type for bits was changed. It resulted in bit variables becoming
4728 global, which is not permitted in PIC 14 assembly output.
4730 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4732 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4743 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4745 A few small changes that speed up the peephole optimizer.
4749 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4751 Try to make the peephole optimizer smarter by maintaining
4752 an association between the assembly source code and the
4753 iCodes that originated them. Put this information to use
4754 with a new peephole rule condition "notVolatile" so that
4755 the rules can be aggressive yet still safe.
4760 * src/mcs51/peeph.def
4762 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4766 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4767 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4768 if the left or right operand symbols have the accuse flag set.
4770 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4772 Changed the type of the result of the ! (NOT) operator to char;
4773 previously it returned the same type as the source. This allows
4774 us to eliminate all the genFloatNot functions (all of its target
4775 implementations were very buggy) since !float can use the same
4778 * src/SDCCicode.c (ast2iCode): ! returns char
4779 * src/mcs51/gen.c (genNot, genNotFloat),
4780 * src/ds390/gen.c (genNot, genNotFloat),
4781 * src/z80/gen.c (genNot, genNotFloat),
4782 * src/pic/gen.c (genNot, genNotFloat),
4783 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
4785 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4787 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4788 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4789 during interrupts. Ensure WSAVE is located at a shared bank address.
4790 2. Fixed page selection in some places
4791 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4792 the registers name strings.
4793 4. Fixed "signed / unsigned compare" compiler warnings.
4794 5. The PIC port manages its own allocation of the general purpose
4795 registers, but makes no attempt to reuse them. As a result when
4796 compiling it soon runs out of general purpose registers. Some
4797 additional code was added to the files pcode.c and device.c to walk
4798 through the function call tree and rename the registers so that they
4808 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4809 genPlus() & genMinus() when the result is the same as left or right

4815 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4817 Made bitfield a distinct type from bit so that bitfields
4818 convert as per ANSI C and bits retain their traditional
4819 boolean style behaviour. Implemented bitfield support in
4827 * src/ds390/gen.c: bit v bitfield split
4828 * src/z80/gen.c: New support for bitfields
4829 * support/regression/tests/bitfields.c: reenabled z80,
4832 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4834 Rules 246.x, 247.x relate to bitfields, the others speed up
4835 access to xdata mapped I/O devices.
4837 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4839 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4841 Cleaned up genPackBits and genUnpackBits and added two helper
4842 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4843 for literal assignments in genPackBits (thanks to Frieder for
4849 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4851 Fixed bug #748310 (pointer to function type mishandled when the
4852 function name is omitted). Also fixed a SIGSEGV when a function
4853 attribute (reentrant, etc) is used on a non-function or on a
4854 function but misplaced before the parameter list.
4856 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4858 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4859 * support/Util/SDCCerr.h,
4860 * support/Util/SDCCerr.c: Added func attr misuse error msg

4881 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4883 Made the constant following the "interrupt" keyword optional. If
4884 omitted, the function will not automatically be given an entry
4885 in the interrupt vector table (similar to #pragma NOIV, but
4886 less syntacticly kludgy). The interrupt number is also now
4887 range checked. Also fixed a bug in the high order bit example
4894 * support/Util/SDCCerr.c
4895 * support/Util/SDCCerr.h
4898 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4900 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4901 * src/SDCCicode.c (operandOperation): rewritten some ops
4902 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4903 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4905 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4906 be re-activated by defining REDUCE_LITERALS)
4907 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4908 unsigned, but are signed by default
4909 * src/SDCCval.c (constVal): rearranged
4910 * src/SDCCval.c (valMod): preliminary fix
4911 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4953 constants are unsigned; added recognition of "u" flag for unsigned
4954 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4955 * src/SDCCval.c (valDiv, valMod): fixed signdness
4956 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4957 signedness of modulo, left and right shift

5363 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5364 the regression tests I'm not brave enough to enable 245.b, 245.c
5365 * doc/sdccman.lyx: added latex preamble for hyperref package.
5366 Using pdflatex this will give you a hyperlinked pdf file with
5367 bookmarks. (prepend '%' before /usepackage if this breaks something)

5405 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5407 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5408 it can be defined with CFLAGS when running configure
5409 * src/SDCCmain.c: fixed compiling + linking with object files
5411 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5414 added --disable-pic16-port
5415 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5416 * src/SDCCmain.c: linkOptions is changed to set *,
5417 added if/endif conditional macros to remove options help
5418 messages from optionsTable when a port is not configured, added
5419 support for the PIc16 port in the ports table, when executing
5420 the compiler with no port specified on command line, a default
5421 port is selected with the new macro DEFAULT_PORT which is
5422 defined in port.h, in setDefaultOptions() linkOptions is removed
5423 from initialization assignment, since now it is a set,
5424 parseCmdLine uses setParseWithComma for linkOptions, in
5425 linkEdit() linkOptions are accessed with new function indexSet()
5426 which returns the i'th item of a set variable. See SDCCset.c, in
5427 linkEdit() when calling buildCmdLine(), added linkOptions as
5428 last argument. Now users can pass arguments to gplink via the
5429 -Wl option, main() uses pic16glue() to glue up pic16 programs

5441 * src/pic16/glue.c: commented out some error producing lines
5442 * src/pic16/main.c: __config directives are commented out to stop
5443 gpasm complaining and test the linkage with gplink, _linkCmd and
5444 _asmCmd changed to be more gplink and gpasm friendly
5445 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5446 produced an error when parsed, peep rule 12 is added to utilize
5447 movff, but it is commented out since the pCode does not support
5448 yet a command with 2 address arguments
5450 2003-05-18 <johan AT balder>
5452 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5453 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5479 2003-05-11 Borut Razem <borut.razem AT siol.net>
5481 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5482 the path of bin directory, so that PATH is the only env. variable, which has to be set
5483 in case of standard installation.
5484 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6554 Changes to aslink (All the changes are marked with 'JCF'):
6556 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6559 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6560 area BSEG. Also moves, if possible, the DATA area down into the internal
6561 ram so more space is available.
6563 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6566 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6567 not bytes. Function summary() which creates a memory usage summary
6568 file with extension .mem. Reports of overlaping stack and small stack
6569 size. If the space for the stack is less than 16 bytes aslink trows a
6572 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6573 the 8051. Option 'y' for memory summary output file.
6575 Changes to sdcc (All the changes are marked with 'JCF'):
6577 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6579 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6580 overlaying area for it (uses RegBankUsed[4]).
6582 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6583 bank zero as used by default. By default aslink locates the stack
6584 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6585 the creation of the .mem file. Delegates the allocation of data area
6586 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6587 the begining of the stack area to aslink.
6589 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6590 glue() in SDCCglue.c creates an area for it.
6592 2002-09-03 Borut Razem <borut.razem AT siol.net>
6593 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6594 sdcc/src/pic/glue.c:
6595 introduced atexit() handler for teporay files removal in case of
6596 errors, assertions, ...
6598 2002-08-29 Borut Razem <borut.razem AT siol.net>
6599 * sdcc/support/cpp2/auto-host_vc_in.h:
6600 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6601 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6602 Maybe there is a similar problem with BORLANDC? It should be checked!
6604 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6605 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6606 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6607 was not executed, and the compiler (cl) launched a warning:
6608 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6610 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6611 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6613 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6614 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6616 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6617 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6618 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6619 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6620 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6621 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6622 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6623 - added Release configuration in VS projects
6624 - review of compiler an linker options
6625 - VC .exe files are generated in bin_vc directory, not to interfere
6626 with binaries generated from other projects (cygwin, mingw, bcc ...)
6628 * sdcc/src/yacc.dsp: added
6630 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6631 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6632 and insert the version number definitions from .version
6634 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6636 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6637 added - genarate auto-host.h using auto-host_vc_in.h as template
6640 removed from CVS, generated automatically
6642 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6643 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6645 2002-08-11 Borut Razem <borut.razem AT siol.net>
6646 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6648 2002-08-10 Borut Razem <borut.razem AT siol.net>
6649 * src/SDCCmain.c (main):
6650 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6651 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6652 The consequence was that some temporary files were not removed.
6655 unification of code in functions tempfilename() and tempfile():
6656 function tempnam() is defined in Visual Studio 6.0 and .NET
6658 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6660 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6661 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6662 - removed compiler command line option /WX: Treats all warnings as errors
6663 - update a list of source files, included into the project
6665 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6666 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6667 changed project type to Generic Project so that can be correcly converted to VS.NET project
6669 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6671 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6673 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6675 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6676 added return 0 statements after assert() to make compiler happy
6678 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6679 added newline in the def file to keep MSC compiler satisfied
6681 * sdcc/src/z80/gen.c:
6682 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6683 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6684 - solved MSC error in function aopDump()
6686 * sdcc_vc.h: define PREFIX as "\\sdcc"
6688 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6689 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6732 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6734 Added "char *Processor" field to the port structure.
6737 Added -p option. Allows port dependent processor to be specified.
6740 Initialized the new field char *Processor field to NULL in all ports
6743 Compiler generated registers for interrupt context saving
6744 were not getting allocated.
6746 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6749 Fixed left shift. Will promote the left side of a left shift
6750 if a) left shifting more than size of operand or b) when assigned
6751 to something size > size of left side
6753 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6755 tons of changes. Register allocation has been
6756 rewritten. Added customization for the various PICs. Flow

6861 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6863 * sdcc/src/SDCCloop.c:
6864 Previous fix was not good. basic blocks that have "break" or "return" are
6865 not really partof a loop , but live ranges used in these blocks should
6866 be live thru the entire loop, so set partOfLoop but don't add them to
6869 2002-02-21 <johan AT FRIJA>
6871 * src/SDCCcse.c: fixed bug #514308
6873 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6877 statement inside a loop, it was not being considered part of the loop.
6879 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6881 2002-02-10 Karl Bongers <karl AT turbobit.com>
6884 Fixed up SDCDB debugger somewhat. Updated debugger/README
6885 with lots of comments and notes.
6887 * device/examples/test2.c:
6888 Fix bug, "red" variable not being initialized(compiler complained).
