11 Adding support for replacing ljmps with sjmps in jumptables
12 generated for switch statements. For now you need to set the
13 environment variable SDCC_SJMP_JUMPTABLE to enable this.
14 Now 4 algorithms for mcs51 jumptable generation are used:
15 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
16 addresses loaded pc-relative for up to 112 cases and stack-pushing
17 target addresses loaded with offset from dptr for up to 256 cases.
19 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
20 * src/mcs51/main.c: adapted constants for switch table generation
21 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

43 Large cummulative patch for pic16 port.
44 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
45 to call when a stack overflow occurs,
46 * (malloc.h): added CVS Id tag,
47 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
49 * added libc directory. The current version of LibC contains string
50 functions, ctype functions and macros and some functions of the
51 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
52 be extensively tested in the future. Standard disclaimer here.
53 Library is not automatically build yet. But one can build it by
54 invoking 'make' inside the libc directory.
55 * added ADC library under libio. Preliminary version yet.
57 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
58 * src/pic16/gen.c (aopForRemat): asmop size is filled by
59 aopForRemat() now and not by pic16_aopOp(),

65 * (pic16_storeForReturn): optimized return of 0,
66 * (genCmp): experimental code for new genCmp which uses PIC18's
67 special compare&skip instructions. Initial tests fail some times
68 with variables grater than 1 byte in size, so new code is disabled,
69 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
71 * (genCast): began a fix to optimize the casting of a bit to another
72 bit, now assigning a bitfield to another bitfield will fail, sorry,
73 * src/pic16/main.c: disabled the use of lr-support feature,
74 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
75 * added some function prototypes, added function _debugf prototype,
76 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
77 bits with offset (case PO_GPR_BIT),
78 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
80 * (isBankInstruction): modified to return 0 for no banking instruction,
81 and 1 for banking instruction,
82 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
83 caused stop processing pCodes after a inline assembly block,
84 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
85 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
86 registers when it shouldn't,
87 * src/pic16/ralloc.c (allocReg): add preliminary support for
88 supporting a limited set of temporary registers,
90 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

95 (loadRegFromAop): recognize CLRH optimization,
96 (genFunction): optimize RECEIVE iCodes in reentrant functions
98 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
100 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3095 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3097 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3098 loaded with the linker search paths (-L arguments) and the libraries
3099 to be linked with the current source (-l arguments). Changes
3100 currently will affect only the pic16 port.
3101 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3102 include path the port specific paths and port specific libraries,
3103 * gplink command now contains the $3 argument,
3104 * src/pic16/device.h,
3105 * src/pic16/device.c,: structure PIC_device is made public and
3106 renamed to PIC16_device, the same for variable Pics which is renamed

3121 Documenting changes from previous commits.
3122 * configure.in (version 1.56),
3123 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3124 when generating output files to configure the pic16 library,
3125 but now I've commented it out, since gputils aren't installed in the
3126 SF compile farm, so library won't compile
3128 * device/lib/Makefile.in (version 1.56): initially I've added in
3129 target 'all' the prerequestive 'model-pic16' so it compiled the
3130 pic16 library, but now I've commented it out for the same reasons
3132 * added targets 'model-pic16' and 'objects-pic16' to compile the
3134 * added target 'port-specific-objects-pic16' to handle the
3135 generated libraries and copy them into the build/ directory
3136 * added target 'clean-intermediate-pic16' to clean intermediate
3137 files into pic16 directory
3138 * in target 'installdirs' added line to create directory pic16 in
3139 the installation path
3141 * device/include/Makefile.in (version 1.11): in target 'install'
3142 added lines to copy all header files to installation path,
3143 * in target 'installdirs' added line create directory for pic16
3144 headers in the installation path
3146 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3157 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3159 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3160 option so that it actually works. Made it specific to the z80, since
3161 the gbz80 doesn't have these kinds of I/O ports.

3231 all over. Telling LaTeX to be less strict with word spacing
3232 to better keep the right margin. Changed some notes about
3233 maintainance of the ports in section 3.2.1 - is it OK like this?
3235 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3273 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3275 * src/pic16/peeph.def: all peepholes with movff are commented out,
3276 because there is a problem in the pcode peep optimizer,
3277 * src/pic16/ralloc.c: the register allocator can now reuse local

3370 include information about variables allocated to the overlay
3373 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3375 * as/mcs51/lkmain.c: Help about -Y option

3387 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3389 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3390 (default behaviour).
3392 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3394 A python script to validate compiler diagnostic messages. It can be
3395 used to verify that sdcc complains about bad c source code and
3396 gives a good location of the error.
3397 * support/valdiag/Makefile,
3398 * support/valdiag/valdiag.py,
3399 * support/valdiag/tests/*
3401 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3414 * src/common.h: added ifndef/define/endif macros
3415 around the header file.
3416 Bug reported from Jesus Calvino-Fraga
3418 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3420 * sdcc.spec: updated
3421 * device/include/Makefile.in: don't install CVS directories
3422 * device/lib/Makefile.in: added removal of CVS directories after install
3423 * doc/Makefile: fixed install, added local_icons
3424 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3425 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3426 * src/ds390/gen.c (genRightShift): fixed bug #870788
3427 * src/SDCCast.c (decorateType): fixed bug #870781
3429 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3431 PIC16 port related changes:
3432 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3433 added variable stackPos,
3435 * gen.c: genCall, assignResultValue: added support for
3436 pushing/retrieving function parameters to/from stack,
3437 genFunction,genEndFunction: setup stack frame for the
3439 genAddrOf: will be changed according to bug 863624
3441 * added files genutils.c and genutils.h which contain gen*
3442 debugged and optimised functions extracted from gen.c
3444 * glue.c: added variable 'externs' which holds extern symbols,
3445 pic16emitRegularMap: is modified to properly handle relocatable
3446 symbols under the new scheme,
3447 pic16createInterruptVect: is modified
3448 pic16printPublics: is modified to emit 'global' assembler directives,
3449 added pic16_printExterns to print extern symbols,
3450 pic16glue: initializes stack/frame pointer in the beginning of
3451 the assembly output. Temporary hack, will be corrected later,
3452 because gplink yet does not support stack and SDCC does not
3453 yet support a type of crt0.o object to create the final binary.
3455 * Removed many lines that contain 8051 legacy code.
3456 * The code is finally placed under a 'code' directive.
3457 * Added port specific options.
3459 * _process_pragma: simplified since now we do not need *special*
3460 include file to define SFR registers. But a separate header
3461 will be needed. This will be developed later.
3462 * _pic16_parseOptions: added, parses port specific options:
3463 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3464 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3465 --preplace-udata-with=
3467 * _pic16_setDefaultOptions: modified to initialize section names,
3468 but hack is temporarly out of order since it needs improvement.
3469 * _pic16_genAssemblerPreamble: configuration words are emitted by
3470 their address instead of their name. This part is incomplete and
3471 supports only the 18Fxx2 devices. Other devices will emit an error
3472 during assembly since they do not contain the same set of config
3474 * _pic16_genIVT: is modified,
3476 * pcode.c: added definitions for some hardware registers that are needed
3478 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3479 All PCI entries are updated. Now LFSR is supported.
3480 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3481 * added pic16_newpCodeOpLit2 to support instructions with
3482 two literal arguments
3483 * pic16_pCode2str: corrected code that emits assembler instructions
3484 with two literal operands and those that have an access bit modifier
3485 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3486 this fixes a bug which caused some labels to be lost, when an
3487 assembler directive was added, i.e. banksel,
3488 * pic16_FixRegisterBanking: improved logic that causes the insertion
3490 * InlineFunction: functions that are called once, are not any more
3491 inlined. This can be a port option in the future,
3493 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3495 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3496 hold the corresponding uninitialized symbols,
3497 * pic16_allocProcessorRegister: registers have explicit marked the
3499 * pic16_allocInternalRegister: registers are explicit marked as
3501 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3502 processing list, so bit registers were lost,
3505 * ralloc.h: added field 'accessBank' and original symbol operand
3506 in register definition,
3507 * removed the field isMapped from register definition,
3509 ** Several functions have been removed from various sources:
3510 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3511 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3512 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3513 pic16_assignRelocatableRegisters
3515 ** others have been introduced:
3516 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3517 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3519 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3521 * support/scripts/inc2h.pl: changed definition of BIT_AT
3522 to emit 'sbit at' instead of 'bit at'. This was a request.
3524 PIC16 port related preliminary changes:
3525 * gen.c: prefixed function popRegFromString with
3526 pic16_ and all references to it corrected
3527 * pcode.c: all pic16_pc_* hardware registers prefixed
3528 with underscore (_),
3529 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3530 * ralloc.c: newReg(): when register is REG_SFR then
3531 set address to rIdx,
3532 pic16_allocProcessorRegister(): marks register wasUsed=0
3533 pic16_writeUsedRegs(): added a call to assign processor
3534 registers via pic16_assignFixedRegisters
3536 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3538 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3539 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3540 variables in unused register banks. Also the SSEG is placed
3541 wherever there is enough space for it, and IDATA can be anywhere
3542 in internal RAM. For now compile using -Wl-Y[stack_size].
3543 The mem file is different for this option as well, since it
3544 makes no sense of talking about DSEG lenght.
3546 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3548 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3549 in certain cases, e.g. when ROM assignment, patch provided
3550 from Albert den Haan.
3552 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4575 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4576 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4595 A few small changes that speed up the peephole optimizer.
4599 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4601 Try to make the peephole optimizer smarter by maintaining
4602 an association between the assembly source code and the
4603 iCodes that originated them. Put this information to use
4604 with a new peephole rule condition "notVolatile" so that
4605 the rules can be aggressive yet still safe.
4610 * src/mcs51/peeph.def
4612 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4616 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4617 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4618 if the left or right operand symbols have the accuse flag set.
4620 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4622 Changed the type of the result of the ! (NOT) operator to char;
4623 previously it returned the same type as the source. This allows
4624 us to eliminate all the genFloatNot functions (all of its target
4625 implementations were very buggy) since !float can use the same

4637 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4638 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4639 during interrupts. Ensure WSAVE is located at a shared bank address.
4640 2. Fixed page selection in some places
4641 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4642 the registers name strings.
4643 4. Fixed "signed / unsigned compare" compiler warnings.
4644 5. The PIC port manages its own allocation of the general purpose
4645 registers, but makes no attempt to reuse them. As a result when
4646 compiling it soon runs out of general purpose registers. Some
4647 additional code was added to the files pcode.c and device.c to walk
4648 through the function call tree and rename the registers so that they
4658 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4665 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4667 Made bitfield a distinct type from bit so that bitfields
4668 convert as per ANSI C and bits retain their traditional
4669 boolean style behaviour. Implemented bitfield support in
4677 * src/ds390/gen.c: bit v bitfield split
4678 * src/z80/gen.c: New support for bitfields

4685 access to xdata mapped I/O devices.
4687 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4689 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4691 Cleaned up genPackBits and genUnpackBits and added two helper
4692 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4693 for literal assignments in genPackBits (thanks to Frieder for
4699 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4701 Fixed bug #748310 (pointer to function type mishandled when the
4702 function name is omitted). Also fixed a SIGSEGV when a function
4703 attribute (reentrant, etc) is used on a non-function or on a
4704 function but misplaced before the parameter list.

4731 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4733 Made the constant following the "interrupt" keyword optional. If
4734 omitted, the function will not automatically be given an entry
4735 in the interrupt vector table (similar to #pragma NOIV, but
4736 less syntacticly kludgy). The interrupt number is also now
4737 range checked. Also fixed a bug in the high order bit example

5255 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5257 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5258 it can be defined with CFLAGS when running configure
5259 * src/SDCCmain.c: fixed compiling + linking with object files
5261 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5263 * configure.in: configure for pic16 port,
5264 added --disable-pic16-port
5265 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5266 * src/SDCCmain.c: linkOptions is changed to set *,
5267 added if/endif conditional macros to remove options help
5268 messages from optionsTable when a port is not configured, added
5269 support for the PIc16 port in the ports table, when executing
5270 the compiler with no port specified on command line, a default
5271 port is selected with the new macro DEFAULT_PORT which is
5272 defined in port.h, in setDefaultOptions() linkOptions is removed
5273 from initialization assignment, since now it is a set,
5274 parseCmdLine uses setParseWithComma for linkOptions, in
5275 linkEdit() linkOptions are accessed with new function indexSet()
5276 which returns the i'th item of a set variable. See SDCCset.c, in
5277 linkEdit() when calling buildCmdLine(), added linkOptions as
5278 last argument. Now users can pass arguments to gplink via the
5279 -Wl option, main() uses pic16glue() to glue up pic16 programs
5280 * src/SDCCpeeph.c: various changes to support pic16

5291 * src/pic16/glue.c: commented out some error producing lines
5292 * src/pic16/main.c: __config directives are commented out to stop
5293 gpasm complaining and test the linkage with gplink, _linkCmd and
5294 _asmCmd changed to be more gplink and gpasm friendly
5295 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5296 produced an error when parsed, peep rule 12 is added to utilize
5297 movff, but it is commented out since the pCode does not support
5298 yet a command with 2 address arguments
5300 2003-05-18 <johan AT balder>

5329 2003-05-11 Borut Razem <borut.razem AT siol.net>
5331 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6337 * src/SDCCicode.c: fixed array add
6339 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6340 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6341 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6343 2003-01-04 <johan AT balder>
6345 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6347 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6348 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6350 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6351 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6360 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6361 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6363 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6365 * in \sdcc\as\mcs51\ changed these files in order to create an
6366 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6367 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6368 following files to include the previous two files: aslink.dsp,
6369 Makefile.aslink, Makefile.bcc, and Makefile.in.
6371 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6372 .adb instead of .cdb
6374 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6376 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6377 value from option --iram-size.
6379 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6381 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6384 2002-09-18 <wiml AT hhhh.org>
6386 * SDCClrange.h: exposed setFromRange() and setToRange()
6387 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6388 packRegsForAccUse() (bug 542397)
6389 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6390 multiple times and emitting the fetch operations more than once
6391 added aopGetUsesAcc() function to allow binary operators to
6392 fetch their operands in the correct order; made genMinus() emit
6393 compact code for X = LITERAL - Y
6395 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6396 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6397 sprintf() in line 1267.
6399 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6400 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6403 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6404 Changes to aslink (All the changes are marked with 'JCF'):
6406 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6409 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6410 area BSEG. Also moves, if possible, the DATA area down into the internal
6411 ram so more space is available.
6413 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6416 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6417 not bytes. Function summary() which creates a memory usage summary
6418 file with extension .mem. Reports of overlaping stack and small stack
6419 size. If the space for the stack is less than 16 bytes aslink trows a
6422 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6423 the 8051. Option 'y' for memory summary output file.
6425 Changes to sdcc (All the changes are marked with 'JCF'):
6427 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6429 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6430 overlaying area for it (uses RegBankUsed[4]).
6432 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6433 bank zero as used by default. By default aslink locates the stack
6434 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6435 the creation of the .mem file. Delegates the allocation of data area
6436 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6437 the begining of the stack area to aslink.
6439 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6440 glue() in SDCCglue.c creates an area for it.
6442 2002-09-03 Borut Razem <borut.razem AT siol.net>
6443 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6444 sdcc/src/pic/glue.c:
6445 introduced atexit() handler for teporay files removal in case of
6446 errors, assertions, ...
6448 2002-08-29 Borut Razem <borut.razem AT siol.net>
6449 * sdcc/support/cpp2/auto-host_vc_in.h:
6450 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6451 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6452 Maybe there is a similar problem with BORLANDC? It should be checked!
6454 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6455 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6456 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6457 was not executed, and the compiler (cl) launched a warning:
6458 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6460 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6461 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6463 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6464 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6466 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6467 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6468 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6469 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6470 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6471 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6472 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6473 - added Release configuration in VS projects
6474 - review of compiler an linker options
6475 - VC .exe files are generated in bin_vc directory, not to interfere
6476 with binaries generated from other projects (cygwin, mingw, bcc ...)
6478 * sdcc/src/yacc.dsp: added
6480 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6481 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6482 and insert the version number definitions from .version
6484 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6486 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6487 added - genarate auto-host.h using auto-host_vc_in.h as template
6490 removed from CVS, generated automatically
6492 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6493 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6495 2002-08-11 Borut Razem <borut.razem AT siol.net>
6496 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6498 2002-08-10 Borut Razem <borut.razem AT siol.net>
6499 * src/SDCCmain.c (main):
6500 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6501 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6502 The consequence was that some temporary files were not removed.
6505 unification of code in functions tempfilename() and tempfile():
6506 function tempnam() is defined in Visual Studio 6.0 and .NET
6508 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6510 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6511 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6512 - removed compiler command line option /WX: Treats all warnings as errors
6513 - update a list of source files, included into the project
6515 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6516 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6517 changed project type to Generic Project so that can be correcly converted to VS.NET project
6519 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6521 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6523 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6525 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6526 added return 0 statements after assert() to make compiler happy
6528 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6529 added newline in the def file to keep MSC compiler satisfied
6531 * sdcc/src/z80/gen.c:
6532 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6533 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6534 - solved MSC error in function aopDump()
6536 * sdcc_vc.h: define PREFIX as "\\sdcc"
6538 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6539 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6541 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6542 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6543 - Rewrote the register banking algorithm.
6544 - Added pCode live-range analysis to registers (for now, only non-used and
6545 singly-used registers optimized away)
