2162 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2164 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2165 loaded with the linker search paths (-L arguments) and the libraries
2166 to be linked with the current source (-l arguments). Changes
2167 currently will affect only the pic16 port.
2168 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2169 include path the port specific paths and port specific libraries,
2170 * gplink command now contains the $3 argument,
2171 * src/pic16/device.h,
2172 * src/pic16/device.c,: structure PIC_device is made public and

2188 Documenting changes from previous commits.
2189 * configure.in (version 1.56),
2190 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2191 when generating output files to configure the pic16 library,
2192 but now I've commented it out, since gputils aren't installed in the
2193 SF compile farm, so library won't compile
2195 * device/lib/Makefile.in (version 1.56): initially I've added in
2196 target 'all' the prerequestive 'model-pic16' so it compiled the
2197 pic16 library, but now I've commented it out for the same reasons
2199 * added targets 'model-pic16' and 'objects-pic16' to compile the
2201 * added target 'port-specific-objects-pic16' to handle the
2202 generated libraries and copy them into the build/ directory
2203 * added target 'clean-intermediate-pic16' to clean intermediate
2204 files into pic16 directory
2205 * in target 'installdirs' added line to create directory pic16 in
2206 the installation path

2209 added lines to copy all header files to installation path,
2210 * in target 'installdirs' added line create directory for pic16
2211 headers in the installation path

2226 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2227 option so that it actually works. Made it specific to the z80, since
2228 the gbz80 doesn't have these kinds of I/O ports.
2230 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2232 * device/include/z180.h,

2254 Mainly changes to support compilation of the device libraries
2255 * src/pic16/device.c: stack is allocated via symbol and not
2256 via literal number. The symbol is placed in the corresponding
2257 position of the data ram
2258 * (pic16_dump_section): relocatable and absolute uninitialized
2259 data are now emitted in sorted order to reduce section naming,
2260 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2261 weren't marked as being in the access bank,
2263 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2265 Added portion of GNU PIC Library under the directory
2266 device/include/pic16 and device/lib/pic16. These files
2267 contain the declarations of SFRs for the PIC18Fxx2 devices.
2268 The directory is initialized via configure from toplevel.
2270 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2272 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2297 * doc/sdccman.lyx: Moved and added some sections, small changes
2298 all over. Telling LaTeX to be less strict with word spacing
2299 to better keep the right margin. Changed some notes about
2300 maintainance of the ports in section 3.2.1 - is it OK like this?
2302 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2304 SDCC source changes:
2305 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2311 processor registers declared internally by the port are emitted in
2312 the translation as equates,
2313 * src/pic16/gen.c: inline code is passed unprocessed to the

2454 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2456 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2457 (default behaviour).
2459 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2461 A python script to validate compiler diagnostic messages. It can be
2462 used to verify that sdcc complains about bad c source code and
2463 gives a good location of the error.
2464 * support/valdiag/Makefile,
2465 * support/valdiag/valdiag.py,
2466 * support/valdiag/tests/*

2481 * src/common.h: added ifndef/define/endif macros
2482 around the header file.
2483 Bug reported from Jesus Calvino-Fraga
2485 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2487 * sdcc.spec: updated
2488 * device/include/Makefile.in: don't install CVS directories
2489 * device/lib/Makefile.in: added removal of CVS directories after install
2490 * doc/Makefile: fixed install, added local_icons
2491 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2492 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2493 * src/ds390/gen.c (genRightShift): fixed bug #870788
2494 * src/SDCCast.c (decorateType): fixed bug #870781
2496 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2498 PIC16 port related changes:
2499 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2500 added variable stackPos,
2502 * gen.c: genCall, assignResultValue: added support for
2503 pushing/retrieving function parameters to/from stack,
2504 genFunction,genEndFunction: setup stack frame for the
2506 genAddrOf: will be changed according to bug 863624
2508 * added files genutils.c and genutils.h which contain gen*
2509 debugged and optimised functions extracted from gen.c
2511 * glue.c: added variable 'externs' which holds extern symbols,
2512 pic16emitRegularMap: is modified to properly handle relocatable
2513 symbols under the new scheme,
2514 pic16createInterruptVect: is modified
2515 pic16printPublics: is modified to emit 'global' assembler directives,
2516 added pic16_printExterns to print extern symbols,
2517 pic16glue: initializes stack/frame pointer in the beginning of
2518 the assembly output. Temporary hack, will be corrected later,
2519 because gplink yet does not support stack and SDCC does not
2520 yet support a type of crt0.o object to create the final binary.
2522 * Removed many lines that contain 8051 legacy code.
2523 * The code is finally placed under a 'code' directive.
2524 * Added port specific options.
2526 * _process_pragma: simplified since now we do not need *special*
2527 include file to define SFR registers. But a separate header
2528 will be needed. This will be developed later.
2529 * _pic16_parseOptions: added, parses port specific options:
2530 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2531 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2532 --preplace-udata-with=
2534 * _pic16_setDefaultOptions: modified to initialize section names,
2535 but hack is temporarly out of order since it needs improvement.
2536 * _pic16_genAssemblerPreamble: configuration words are emitted by
2537 their address instead of their name. This part is incomplete and
2538 supports only the 18Fxx2 devices. Other devices will emit an error
2539 during assembly since they do not contain the same set of config
2541 * _pic16_genIVT: is modified,
2543 * pcode.c: added definitions for some hardware registers that are needed
2545 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2546 All PCI entries are updated. Now LFSR is supported.
2547 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2548 * added pic16_newpCodeOpLit2 to support instructions with
2549 two literal arguments
2550 * pic16_pCode2str: corrected code that emits assembler instructions
2551 with two literal operands and those that have an access bit modifier
2552 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2553 this fixes a bug which caused some labels to be lost, when an
2554 assembler directive was added, i.e. banksel,
2555 * pic16_FixRegisterBanking: improved logic that causes the insertion
2557 * InlineFunction: functions that are called once, are not any more
2558 inlined. This can be a port option in the future,
2560 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2562 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2563 hold the corresponding uninitialized symbols,
2564 * pic16_allocProcessorRegister: registers have explicit marked the
2566 * pic16_allocInternalRegister: registers are explicit marked as
2568 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2569 processing list, so bit registers were lost,
2572 * ralloc.h: added field 'accessBank' and original symbol operand
2573 in register definition,
2574 * removed the field isMapped from register definition,
2576 ** Several functions have been removed from various sources:
2577 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2578 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2579 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2580 pic16_assignRelocatableRegisters
2582 ** others have been introduced:
2583 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2584 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2586 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2588 * support/scripts/inc2h.pl: changed definition of BIT_AT
2589 to emit 'sbit at' instead of 'bit at'. This was a request.
2591 PIC16 port related preliminary changes:
2592 * gen.c: prefixed function popRegFromString with
2593 pic16_ and all references to it corrected
2594 * pcode.c: all pic16_pc_* hardware registers prefixed
2595 with underscore (_),
2596 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2597 * ralloc.c: newReg(): when register is REG_SFR then
2598 set address to rIdx,
2599 pic16_allocProcessorRegister(): marks register wasUsed=0
2600 pic16_writeUsedRegs(): added a call to assign processor
2601 registers via pic16_assignFixedRegisters
2603 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2605 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2606 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2607 variables in unused register banks. Also the SSEG is placed
2608 wherever there is enough space for it, and IDATA can be anywhere
2609 in internal RAM. For now compile using -Wl-Y[stack_size].
2610 The mem file is different for this option as well, since it
2611 makes no sense of talking about DSEG lenght.
2613 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2615 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2616 in certain cases, e.g. when ROM assignment, patch provided
2617 from Albert den Haan.
2619 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2760 xdata and data memory on startup. Set the environment variable
2761 SDCC_NOGENRAMCLEAR to disable this.
2762 * src/mcs51/peephole.def,
2763 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
2764 (allows non-interrupt and interrupt code to safely compete for a resource
2765 without the non-interrupt code having to disable interrupts)
2767 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2775 multiply defined with mismatching "at" address.
2777 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2779 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
2780 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

3505 support for standard C idiom of memory mapped variables; for
3506 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3507 to xdata int at 0x1234 tempvar = 1.
3508 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3509 provided by Akiya ISHIDA

3525 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3527 Fixed bug #621531 (const & volatile confusion in the type chain).
3528 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

3608 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3609 iCode properly now. Use getSize instead of nRegs since a & b
3610 aren't part of the nRegs tally.
3612 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3614 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3620 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3621 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3622 fetching of the pointer
3623 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3624 copied from genNearPointerSet()
3625 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3626 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3627 If they pop r0/r1 they must be called in the opposite order than aopOp().
3628 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3629 (resp. --stack-auto), prepared for --xstack

3638 these ports have their own __sdcc_external_start()
3640 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3642 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3643 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3644 type for bits was changed. It resulted in bit variables becoming
3645 global, which is not permitted in PIC 14 assembly output.
3647 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3649 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3662 A few small changes that speed up the peephole optimizer.
3666 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3668 Try to make the peephole optimizer smarter by maintaining
3669 an association between the assembly source code and the
3670 iCodes that originated them. Put this information to use
3671 with a new peephole rule condition "notVolatile" so that
3672 the rules can be aggressive yet still safe.
3677 * src/mcs51/peeph.def
3679 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3683 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3684 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3685 if the left or right operand symbols have the accuse flag set.
3687 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3689 Changed the type of the result of the ! (NOT) operator to char;
3690 previously it returned the same type as the source. This allows
3691 us to eliminate all the genFloatNot functions (all of its target
3692 implementations were very buggy) since !float can use the same
3695 * src/SDCCicode.c (ast2iCode): ! returns char

3702 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3704 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3705 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3706 during interrupts. Ensure WSAVE is located at a shared bank address.
3707 2. Fixed page selection in some places
3708 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3709 the registers name strings.
3710 4. Fixed "signed / unsigned compare" compiler warnings.
3711 5. The PIC port manages its own allocation of the general purpose
3712 registers, but makes no attempt to reuse them. As a result when
3713 compiling it soon runs out of general purpose registers. Some
3714 additional code was added to the files pcode.c and device.c to walk
3715 through the function call tree and rename the registers so that they
3725 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3726 genPlus() & genMinus() when the result is the same as left or right

3732 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3734 Made bitfield a distinct type from bit so that bitfields
3735 convert as per ANSI C and bits retain their traditional
3736 boolean style behaviour. Implemented bitfield support in
3744 * src/ds390/gen.c: bit v bitfield split
3745 * src/z80/gen.c: New support for bitfields
3746 * support/regression/tests/bitfields.c: reenabled z80,
3749 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3751 Rules 246.x, 247.x relate to bitfields, the others speed up
3752 access to xdata mapped I/O devices.
3754 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3756 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3758 Cleaned up genPackBits and genUnpackBits and added two helper
3759 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3760 for literal assignments in genPackBits (thanks to Frieder for
3766 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3768 Fixed bug #748310 (pointer to function type mishandled when the
3769 function name is omitted). Also fixed a SIGSEGV when a function
3770 attribute (reentrant, etc) is used on a non-function or on a
3771 function but misplaced before the parameter list.
3773 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3775 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3776 * support/Util/SDCCerr.h,
3777 * support/Util/SDCCerr.c: Added func attr misuse error msg
3779 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3781 Fixed bug #787649 by anonymous
3782 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

3798 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3800 Made the constant following the "interrupt" keyword optional. If
3801 omitted, the function will not automatically be given an entry
3802 in the interrupt vector table (similar to #pragma NOIV, but
3803 less syntacticly kludgy). The interrupt number is also now
3804 range checked. Also fixed a bug in the high order bit example

4331 added --disable-pic16-port
4332 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4333 * src/SDCCmain.c: linkOptions is changed to set *,
4334 added if/endif conditional macros to remove options help
4335 messages from optionsTable when a port is not configured, added
4336 support for the PIc16 port in the ports table, when executing
4337 the compiler with no port specified on command line, a default
4338 port is selected with the new macro DEFAULT_PORT which is
4339 defined in port.h, in setDefaultOptions() linkOptions is removed
4340 from initialization assignment, since now it is a set,
4341 parseCmdLine uses setParseWithComma for linkOptions, in
4342 linkEdit() linkOptions are accessed with new function indexSet()
4343 which returns the i'th item of a set variable. See SDCCset.c, in
4344 linkEdit() when calling buildCmdLine(), added linkOptions as
4345 last argument. Now users can pass arguments to gplink via the
4346 -Wl option, main() uses pic16glue() to glue up pic16 programs

4358 * src/pic16/glue.c: commented out some error producing lines
4359 * src/pic16/main.c: __config directives are commented out to stop
4360 gpasm complaining and test the linkage with gplink, _linkCmd and
4361 _asmCmd changed to be more gplink and gpasm friendly
4362 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4363 produced an error when parsed, peep rule 12 is added to utilize
4364 movff, but it is commented out since the pCode does not support
4365 yet a command with 2 address arguments

5410 2003-01-04 <johan AT balder>
5412 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5414 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5427 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5428 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5430 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5432 * in \sdcc\as\mcs51\ changed these files in order to create an
5433 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5434 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5435 following files to include the previous two files: aslink.dsp,
5436 Makefile.aslink, Makefile.bcc, and Makefile.in.
5438 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5439 .adb instead of .cdb
5441 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5443 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5444 value from option --iram-size.
5446 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5448 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5451 2002-09-18 <wiml AT hhhh.org>
5453 * SDCClrange.h: exposed setFromRange() and setToRange()
5454 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5455 packRegsForAccUse() (bug 542397)
5456 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5457 multiple times and emitting the fetch operations more than once
5458 added aopGetUsesAcc() function to allow binary operators to
5459 fetch their operands in the correct order; made genMinus() emit
5460 compact code for X = LITERAL - Y
5462 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5463 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5464 sprintf() in line 1267.
5466 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5467 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5470 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5471 Changes to aslink (All the changes are marked with 'JCF'):
5473 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5476 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5477 area BSEG. Also moves, if possible, the DATA area down into the internal
5478 ram so more space is available.
5480 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5483 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5484 not bytes. Function summary() which creates a memory usage summary
5485 file with extension .mem. Reports of overlaping stack and small stack
5486 size. If the space for the stack is less than 16 bytes aslink trows a
5489 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5490 the 8051. Option 'y' for memory summary output file.
5492 Changes to sdcc (All the changes are marked with 'JCF'):
5494 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5496 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5497 overlaying area for it (uses RegBankUsed[4]).
5499 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5500 bank zero as used by default. By default aslink locates the stack
5501 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5502 the creation of the .mem file. Delegates the allocation of data area
5503 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5504 the begining of the stack area to aslink.
5506 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5507 glue() in SDCCglue.c creates an area for it.
5509 2002-09-03 Borut Razem <borut.razem AT siol.net>
5510 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5511 sdcc/src/pic/glue.c:
5512 introduced atexit() handler for teporay files removal in case of
5513 errors, assertions, ...
5515 2002-08-29 Borut Razem <borut.razem AT siol.net>
5516 * sdcc/support/cpp2/auto-host_vc_in.h:
5517 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5518 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5519 Maybe there is a similar problem with BORLANDC? It should be checked!
5521 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5522 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5523 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5524 was not executed, and the compiler (cl) launched a warning:
5525 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5527 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5528 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5530 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5531 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5533 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5534 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5535 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5536 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5537 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5538 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5539 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5540 - added Release configuration in VS projects
5541 - review of compiler an linker options
5542 - VC .exe files are generated in bin_vc directory, not to interfere
5543 with binaries generated from other projects (cygwin, mingw, bcc ...)
5545 * sdcc/src/yacc.dsp: added
5547 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5548 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5549 and insert the version number definitions from .version
5551 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5553 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5554 added - genarate auto-host.h using auto-host_vc_in.h as template
5557 removed from CVS, generated automatically
5559 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5560 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5562 2002-08-11 Borut Razem <borut.razem AT siol.net>
5563 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5565 2002-08-10 Borut Razem <borut.razem AT siol.net>
5566 * src/SDCCmain.c (main):
5567 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5568 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5569 The consequence was that some temporary files were not removed.
5572 unification of code in functions tempfilename() and tempfile():
5573 function tempnam() is defined in Visual Studio 6.0 and .NET
5575 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5577 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5578 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5579 - removed compiler command line option /WX: Treats all warnings as errors
5580 - update a list of source files, included into the project
5582 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5583 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5584 changed project type to Generic Project so that can be correcly converted to VS.NET project
5586 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5588 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5590 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5592 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5593 added return 0 statements after assert() to make compiler happy
5595 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5596 added newline in the def file to keep MSC compiler satisfied
5598 * sdcc/src/z80/gen.c:
5599 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5600 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5601 - solved MSC error in function aopDump()
5603 * sdcc_vc.h: define PREFIX as "\\sdcc"
5605 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5606 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5609 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5610 - Rewrote the register banking algorithm.
5611 - Added pCode live-range analysis to registers (for now, only non-used and
5612 singly-used registers optimized away)
5614 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5616 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

5641 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
5643 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5645 2002-03-28 Johan Knol <johan AT balder>
5647 * src/SDCCval.c: fixed bug #532436
5649 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5651 Added "char *Processor" field to the port structure.
5654 Added -p option. Allows port dependent processor to be specified.
5657 Initialized the new field char *Processor field to NULL in all ports
5660 Compiler generated registers for interrupt context saving
5661 were not getting allocated.
5663 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5666 Fixed left shift. Will promote the left side of a left shift
5667 if a) left shifting more than size of operand or b) when assigned
5668 to something size > size of left side
5670 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5672 tons of changes. Register allocation has been
5673 rewritten. Added customization for the various PICs. Flow
5674 analysis is restructured. ...
5680 Added. device.c is a PIC port hack to accomodate variations
5683 2002-03-13 Michael Hope <michaelh AT vroom>
5685 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5687 2002-03-04 johanknol <johanknol AT manik>
5689 * /src/SDCCval.c: fixed
5691 const unsigned char arr[][2] = { { 0, 1 } };
5692 t18.c:1: error: Initializer element is not constant
5694 2002-03-04 bela <bela AT manik>
5696 * /device/include/mcs51reg.h:
5697 ds89c420 register definition update
5699 2002-03-03 <johan AT FRIJA>
5701 * support/Util/SDCCerr.c: did something, but don't no why anymore
