2148 loaded with the linker search paths (-L arguments) and the libraries
2149 to be linked with the current source (-l arguments). Changes
2150 currently will affect only the pic16 port.
2151 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2152 include path the port specific paths and port specific libraries,
2153 * gplink command now contains the $3 argument,
2154 * src/pic16/device.h,

2171 Documenting changes from previous commits.
2172 * configure.in (version 1.56),
2173 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2174 when generating output files to configure the pic16 library,
2175 but now I've commented it out, since gputils aren't installed in the
2176 SF compile farm, so library won't compile
2178 * device/lib/Makefile.in (version 1.56): initially I've added in
2179 target 'all' the prerequestive 'model-pic16' so it compiled the
2180 pic16 library, but now I've commented it out for the same reasons
2182 * added targets 'model-pic16' and 'objects-pic16' to compile the
2184 * added target 'port-specific-objects-pic16' to handle the
2185 generated libraries and copy them into the build/ directory
2186 * added target 'clean-intermediate-pic16' to clean intermediate
2187 files into pic16 directory
2188 * in target 'installdirs' added line to create directory pic16 in

2210 option so that it actually works. Made it specific to the z80, since
2211 the gbz80 doesn't have these kinds of I/O ports.
2213 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2215 * device/include/z180.h,

2239 via literal number. The symbol is placed in the corresponding
2240 position of the data ram
2241 * (pic16_dump_section): relocatable and absolute uninitialized
2242 data are now emitted in sorted order to reduce section naming,
2243 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2244 weren't marked as being in the access bank,

2248 Added portion of GNU PIC Library under the directory
2249 device/include/pic16 and device/lib/pic16. These files
2250 contain the declarations of SFRs for the PIC18Fxx2 devices.
2251 The directory is initialized via configure from toplevel.

2322 UPPER for immediate operands,
2323 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2325 * src/pic16/peeph.def: all peepholes with movff are commented out,
2326 because there is a problem in the pcode peep optimizer,
2327 * src/pic16/ralloc.c: the register allocator can now reuse local
2328 function symbols for another function. This saves register usage.

2437 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2439 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2440 (default behaviour).
2442 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2444 A python script to validate compiler diagnostic messages. It can be
2445 used to verify that sdcc complains about bad c source code and
2446 gives a good location of the error.
2447 * support/valdiag/Makefile,
2448 * support/valdiag/valdiag.py,
2449 * support/valdiag/tests/*

2468 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2470 * sdcc.spec: updated
2471 * device/include/Makefile.in: don't install CVS directories
2472 * device/lib/Makefile.in: added removal of CVS directories after install
2473 * doc/Makefile: fixed install, added local_icons
2474 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2475 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2476 * src/ds390/gen.c (genRightShift): fixed bug #870788

2479 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2481 PIC16 port related changes:
2482 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2483 added variable stackPos,
2485 * gen.c: genCall, assignResultValue: added support for
2486 pushing/retrieving function parameters to/from stack,
2487 genFunction,genEndFunction: setup stack frame for the
2489 genAddrOf: will be changed according to bug 863624
2491 * added files genutils.c and genutils.h which contain gen*
2492 debugged and optimised functions extracted from gen.c
2494 * glue.c: added variable 'externs' which holds extern symbols,
2495 pic16emitRegularMap: is modified to properly handle relocatable
2496 symbols under the new scheme,
2497 pic16createInterruptVect: is modified
2498 pic16printPublics: is modified to emit 'global' assembler directives,
2499 added pic16_printExterns to print extern symbols,
2500 pic16glue: initializes stack/frame pointer in the beginning of
2501 the assembly output. Temporary hack, will be corrected later,
2502 because gplink yet does not support stack and SDCC does not
2503 yet support a type of crt0.o object to create the final binary.
2505 * Removed many lines that contain 8051 legacy code.
2506 * The code is finally placed under a 'code' directive.
2507 * Added port specific options.
2509 * _process_pragma: simplified since now we do not need *special*
2510 include file to define SFR registers. But a separate header
2511 will be needed. This will be developed later.
2512 * _pic16_parseOptions: added, parses port specific options:
2513 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2514 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2515 --preplace-udata-with=
2517 * _pic16_setDefaultOptions: modified to initialize section names,
2518 but hack is temporarly out of order since it needs improvement.
2519 * _pic16_genAssemblerPreamble: configuration words are emitted by
2520 their address instead of their name. This part is incomplete and
2521 supports only the 18Fxx2 devices. Other devices will emit an error
2522 during assembly since they do not contain the same set of config
2524 * _pic16_genIVT: is modified,
2526 * pcode.c: added definitions for some hardware registers that are needed
2528 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2529 All PCI entries are updated. Now LFSR is supported.
2530 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2531 * added pic16_newpCodeOpLit2 to support instructions with
2532 two literal arguments
2533 * pic16_pCode2str: corrected code that emits assembler instructions
2534 with two literal operands and those that have an access bit modifier
2535 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2536 this fixes a bug which caused some labels to be lost, when an
2537 assembler directive was added, i.e. banksel,
2538 * pic16_FixRegisterBanking: improved logic that causes the insertion
2540 * InlineFunction: functions that are called once, are not any more
2541 inlined. This can be a port option in the future,
2543 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2545 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2546 hold the corresponding uninitialized symbols,
2547 * pic16_allocProcessorRegister: registers have explicit marked the
2549 * pic16_allocInternalRegister: registers are explicit marked as
2551 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2552 processing list, so bit registers were lost,
2555 * ralloc.h: added field 'accessBank' and original symbol operand
2556 in register definition,
2557 * removed the field isMapped from register definition,
2559 ** Several functions have been removed from various sources:
2560 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2561 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2562 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2563 pic16_assignRelocatableRegisters
2565 ** others have been introduced:
2566 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2567 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2569 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2571 * support/scripts/inc2h.pl: changed definition of BIT_AT
2572 to emit 'sbit at' instead of 'bit at'. This was a request.
2574 PIC16 port related preliminary changes:
2575 * gen.c: prefixed function popRegFromString with
2576 pic16_ and all references to it corrected
2577 * pcode.c: all pic16_pc_* hardware registers prefixed
2578 with underscore (_),
2579 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2580 * ralloc.c: newReg(): when register is REG_SFR then
2581 set address to rIdx,
2582 pic16_allocProcessorRegister(): marks register wasUsed=0
2583 pic16_writeUsedRegs(): added a call to assign processor
2584 registers via pic16_assignFixedRegisters
2586 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2588 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2589 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2590 variables in unused register banks. Also the SSEG is placed
2591 wherever there is enough space for it, and IDATA can be anywhere
2592 in internal RAM. For now compile using -Wl-Y[stack_size].
2593 The mem file is different for this option as well, since it
2594 makes no sense of talking about DSEG lenght.
2596 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2598 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2599 in certain cases, e.g. when ROM assignment, patch provided
2600 from Albert den Haan.
2602 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2745 * src/mcs51/peephole.def,
2746 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
2747 (allows non-interrupt and interrupt code to safely compete for a resource

3488 support for standard C idiom of memory mapped variables; for
3489 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3490 to xdata int at 0x1234 tempvar = 1.
3491 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3492 provided by Akiya ISHIDA

3577 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
3578 pcoderegs.h, ralloc.c, ralloc.h
3579 * main.c: added top header and GPL license notice

3603 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3604 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3605 fetching of the pointer
3606 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3607 copied from genNearPointerSet()
3608 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3609 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3610 If they pop r0/r1 they must be called in the opposite order than aopOp().
3611 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3612 (resp. --stack-auto), prepared for --xstack

3621 these ports have their own __sdcc_external_start()
3623 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3625 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3626 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3627 type for bits was changed. It resulted in bit variables becoming
3628 global, which is not permitted in PIC 14 assembly output.
3630 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3632 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3643 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3645 A few small changes that speed up the peephole optimizer.
3649 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3651 Try to make the peephole optimizer smarter by maintaining
3652 an association between the assembly source code and the
3653 iCodes that originated them. Put this information to use
3654 with a new peephole rule condition "notVolatile" so that
3655 the rules can be aggressive yet still safe.
3660 * src/mcs51/peeph.def
3662 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3666 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3667 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3668 if the left or right operand symbols have the accuse flag set.
3670 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3672 Changed the type of the result of the ! (NOT) operator to char;
3673 previously it returned the same type as the source. This allows
3674 us to eliminate all the genFloatNot functions (all of its target
3675 implementations were very buggy) since !float can use the same
3678 * src/SDCCicode.c (ast2iCode): ! returns char
3679 * src/mcs51/gen.c (genNot, genNotFloat),
3680 * src/ds390/gen.c (genNot, genNotFloat),
3681 * src/z80/gen.c (genNot, genNotFloat),
3682 * src/pic/gen.c (genNot, genNotFloat),
3683 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3685 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3687 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3688 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3689 during interrupts. Ensure WSAVE is located at a shared bank address.
3690 2. Fixed page selection in some places
3691 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3692 the registers name strings.
3693 4. Fixed "signed / unsigned compare" compiler warnings.
3694 5. The PIC port manages its own allocation of the general purpose
3695 registers, but makes no attempt to reuse them. As a result when
3696 compiling it soon runs out of general purpose registers. Some
3697 additional code was added to the files pcode.c and device.c to walk
3698 through the function call tree and rename the registers so that they
3708 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3709 genPlus() & genMinus() when the result is the same as left or right
3711 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3715 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3717 Made bitfield a distinct type from bit so that bitfields
3718 convert as per ANSI C and bits retain their traditional
3719 boolean style behaviour. Implemented bitfield support in
3727 * src/ds390/gen.c: bit v bitfield split
3728 * src/z80/gen.c: New support for bitfields
3729 * support/regression/tests/bitfields.c: reenabled z80,
3732 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3734 Rules 246.x, 247.x relate to bitfields, the others speed up
3735 access to xdata mapped I/O devices.
3737 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3739 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3741 Cleaned up genPackBits and genUnpackBits and added two helper
3742 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3743 for literal assignments in genPackBits (thanks to Frieder for
3749 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3751 Fixed bug #748310 (pointer to function type mishandled when the
3752 function name is omitted). Also fixed a SIGSEGV when a function
3753 attribute (reentrant, etc) is used on a non-function or on a
3754 function but misplaced before the parameter list.
3756 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3758 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3759 * support/Util/SDCCerr.h,
3760 * support/Util/SDCCerr.c: Added func attr misuse error msg
3762 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3764 Fixed bug #787649 by anonymous
3765 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
3766 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
3768 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3781 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3783 Made the constant following the "interrupt" keyword optional. If
3784 omitted, the function will not automatically be given an entry
3785 in the interrupt vector table (similar to #pragma NOIV, but
3786 less syntacticly kludgy). The interrupt number is also now
3787 range checked. Also fixed a bug in the high order bit example

3798 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3800 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
3801 * src/SDCCicode.c (operandOperation): rewritten some ops
3802 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3803 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3805 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3806 be re-activated by defining REDUCE_LITERALS)
3807 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3808 unsigned, but are signed by default
3809 * src/SDCCval.c (constVal): rearranged
3810 * src/SDCCval.c (valMod): preliminary fix
3811 * src/SDCCval.c (valCastLiteral): use TYPE_* types
3812 * support/regression/literalop.c: added, work in progress

4316 * src/SDCCmain.c: linkOptions is changed to set *,
4317 added if/endif conditional macros to remove options help
4318 messages from optionsTable when a port is not configured, added
4319 support for the PIc16 port in the ports table, when executing
4320 the compiler with no port specified on command line, a default
4321 port is selected with the new macro DEFAULT_PORT which is
4322 defined in port.h, in setDefaultOptions() linkOptions is removed
4323 from initialization assignment, since now it is a set,
4324 parseCmdLine uses setParseWithComma for linkOptions, in
4325 linkEdit() linkOptions are accessed with new function indexSet()
4326 which returns the i'th item of a set variable. See SDCCset.c, in
4327 linkEdit() when calling buildCmdLine(), added linkOptions as
4328 last argument. Now users can pass arguments to gplink via the
4329 -Wl option, main() uses pic16glue() to glue up pic16 programs

4341 * src/pic16/glue.c: commented out some error producing lines
4342 * src/pic16/main.c: __config directives are commented out to stop
4343 gpasm complaining and test the linkage with gplink, _linkCmd and
4344 _asmCmd changed to be more gplink and gpasm friendly
4345 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4346 produced an error when parsed, peep rule 12 is added to utilize
4347 movff, but it is commented out since the pCode does not support
4348 yet a command with 2 address arguments
4350 2003-05-18 <johan AT balder>
4352 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4353 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5391 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5393 2003-01-04 <johan AT balder>
5395 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5397 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5410 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5411 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5413 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5415 * in \sdcc\as\mcs51\ changed these files in order to create an
5416 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5417 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5418 following files to include the previous two files: aslink.dsp,
5419 Makefile.aslink, Makefile.bcc, and Makefile.in.
5421 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5422 .adb instead of .cdb
5424 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5426 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5427 value from option --iram-size.
5429 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5431 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5434 2002-09-18 <wiml AT hhhh.org>
5436 * SDCClrange.h: exposed setFromRange() and setToRange()
5437 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5438 packRegsForAccUse() (bug 542397)
5439 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5440 multiple times and emitting the fetch operations more than once
5441 added aopGetUsesAcc() function to allow binary operators to
5442 fetch their operands in the correct order; made genMinus() emit
5443 compact code for X = LITERAL - Y
5445 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5446 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5447 sprintf() in line 1267.
5449 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5450 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5453 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5454 Changes to aslink (All the changes are marked with 'JCF'):
5456 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5459 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5460 area BSEG. Also moves, if possible, the DATA area down into the internal
5461 ram so more space is available.
5463 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5466 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5467 not bytes. Function summary() which creates a memory usage summary
5468 file with extension .mem. Reports of overlaping stack and small stack
5469 size. If the space for the stack is less than 16 bytes aslink trows a
5472 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5473 the 8051. Option 'y' for memory summary output file.
5475 Changes to sdcc (All the changes are marked with 'JCF'):
5477 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5479 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5480 overlaying area for it (uses RegBankUsed[4]).
5482 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5483 bank zero as used by default. By default aslink locates the stack
5484 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5485 the creation of the .mem file. Delegates the allocation of data area
5486 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5487 the begining of the stack area to aslink.
5489 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5490 glue() in SDCCglue.c creates an area for it.
5492 2002-09-03 Borut Razem <borut.razem AT siol.net>
5493 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5494 sdcc/src/pic/glue.c:
5495 introduced atexit() handler for teporay files removal in case of
5496 errors, assertions, ...
5498 2002-08-29 Borut Razem <borut.razem AT siol.net>
5499 * sdcc/support/cpp2/auto-host_vc_in.h:
5500 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5501 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5502 Maybe there is a similar problem with BORLANDC? It should be checked!
5504 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5505 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5506 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5507 was not executed, and the compiler (cl) launched a warning:
5508 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5510 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5511 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5513 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5514 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5516 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5517 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5518 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5519 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5520 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5521 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5522 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5523 - added Release configuration in VS projects
5524 - review of compiler an linker options
5525 - VC .exe files are generated in bin_vc directory, not to interfere
5526 with binaries generated from other projects (cygwin, mingw, bcc ...)
5528 * sdcc/src/yacc.dsp: added
5530 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5531 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5532 and insert the version number definitions from .version
5534 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5536 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5537 added - genarate auto-host.h using auto-host_vc_in.h as template
5540 removed from CVS, generated automatically
5542 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5543 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5545 2002-08-11 Borut Razem <borut.razem AT siol.net>
5546 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5548 2002-08-10 Borut Razem <borut.razem AT siol.net>
5549 * src/SDCCmain.c (main):
5550 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5551 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5552 The consequence was that some temporary files were not removed.
5555 unification of code in functions tempfilename() and tempfile():
5556 function tempnam() is defined in Visual Studio 6.0 and .NET
5558 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5560 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5561 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5562 - removed compiler command line option /WX: Treats all warnings as errors
5563 - update a list of source files, included into the project
5565 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5566 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5567 changed project type to Generic Project so that can be correcly converted to VS.NET project
5569 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5571 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5573 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5575 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5576 added return 0 statements after assert() to make compiler happy
5578 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5579 added newline in the def file to keep MSC compiler satisfied
5581 * sdcc/src/z80/gen.c:
5582 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5583 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5584 - solved MSC error in function aopDump()
5586 * sdcc_vc.h: define PREFIX as "\\sdcc"
5588 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5589 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5591 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5592 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5593 - Rewrote the register banking algorithm.
5594 - Added pCode live-range analysis to registers (for now, only non-used and
5595 singly-used registers optimized away)
5597 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

5628 2002-03-28 Johan Knol <johan AT balder>
5630 * src/SDCCval.c: fixed bug #532436
5632 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5634 Added "char *Processor" field to the port structure.
5637 Added -p option. Allows port dependent processor to be specified.
5640 Initialized the new field char *Processor field to NULL in all ports
5643 Compiler generated registers for interrupt context saving
5644 were not getting allocated.
5646 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5649 Fixed left shift. Will promote the left side of a left shift
5650 if a) left shifting more than size of operand or b) when assigned
5651 to something size > size of left side
5653 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5655 tons of changes. Register allocation has been
5656 rewritten. Added customization for the various PICs. Flow
5657 analysis is restructured. ...
5663 Added. device.c is a PIC port hack to accomodate variations
5666 2002-03-13 Michael Hope <michaelh AT vroom>
5668 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
