1974 loaded with the linker search paths (-L arguments) and the libraries
1975 to be linked with the current source (-l arguments). Changes
1976 currently will affect only the pic16 port.
1977 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1978 include path the port specific paths and port specific libraries,
1979 * gplink command now contains the $3 argument,
1980 * src/pic16/device.h,

1998 * configure.in (version 1.56),
1999 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2000 when generating output files to configure the pic16 library,
2001 but now I've commented it out, since gputils aren't installed in the
2002 SF compile farm, so library won't compile
2004 * device/lib/Makefile.in (version 1.56): initially I've added in
2005 target 'all' the prerequestive 'model-pic16' so it compiled the
2006 pic16 library, but now I've commented it out for the same reasons
2008 * added targets 'model-pic16' and 'objects-pic16' to compile the
2010 * added target 'port-specific-objects-pic16' to handle the
2011 generated libraries and copy them into the build/ directory

2323 pic16createInterruptVect: is modified
2324 pic16printPublics: is modified to emit 'global' assembler directives,
2325 added pic16_printExterns to print extern symbols,
2326 pic16glue: initializes stack/frame pointer in the beginning of
2327 the assembly output. Temporary hack, will be corrected later,
2328 because gplink yet does not support stack and SDCC does not
2329 yet support a type of crt0.o object to create the final binary.
2331 * Removed many lines that contain 8051 legacy code.
2332 * The code is finally placed under a 'code' directive.
2333 * Added port specific options.
2335 * _process_pragma: simplified since now we do not need *special*
2336 include file to define SFR registers. But a separate header
2337 will be needed. This will be developed later.
2338 * _pic16_parseOptions: added, parses port specific options:
2339 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2340 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2341 --preplace-udata-with=
2343 * _pic16_setDefaultOptions: modified to initialize section names,
2344 but hack is temporarly out of order since it needs improvement.
2345 * _pic16_genAssemblerPreamble: configuration words are emitted by
2346 their address instead of their name. This part is incomplete and
2347 supports only the 18Fxx2 devices. Other devices will emit an error
2348 during assembly since they do not contain the same set of config
2350 * _pic16_genIVT: is modified,
2352 * pcode.c: added definitions for some hardware registers that are needed
2354 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2355 All PCI entries are updated. Now LFSR is supported.
2356 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2357 * added pic16_newpCodeOpLit2 to support instructions with
2358 two literal arguments
2359 * pic16_pCode2str: corrected code that emits assembler instructions
2360 with two literal operands and those that have an access bit modifier
2361 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2362 this fixes a bug which caused some labels to be lost, when an
2363 assembler directive was added, i.e. banksel,
2364 * pic16_FixRegisterBanking: improved logic that causes the insertion
2366 * InlineFunction: functions that are called once, are not any more
2367 inlined. This can be a port option in the future,
2369 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2371 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2372 hold the corresponding uninitialized symbols,
2373 * pic16_allocProcessorRegister: registers have explicit marked the
2375 * pic16_allocInternalRegister: registers are explicit marked as
2377 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2378 processing list, so bit registers were lost,
2381 * ralloc.h: added field 'accessBank' and original symbol operand
2382 in register definition,
2383 * removed the field isMapped from register definition,
2385 ** Several functions have been removed from various sources:
2386 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2387 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2388 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2389 pic16_assignRelocatableRegisters
2391 ** others have been introduced:
2392 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2393 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2395 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2397 * support/scripts/inc2h.pl: changed definition of BIT_AT
2398 to emit 'sbit at' instead of 'bit at'. This was a request.
2400 PIC16 port related preliminary changes:
2401 * gen.c: prefixed function popRegFromString with
2402 pic16_ and all references to it corrected
2403 * pcode.c: all pic16_pc_* hardware registers prefixed
2404 with underscore (_),
2405 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2406 * ralloc.c: newReg(): when register is REG_SFR then
2407 set address to rIdx,
2408 pic16_allocProcessorRegister(): marks register wasUsed=0
2409 pic16_writeUsedRegs(): added a call to assign processor
2410 registers via pic16_assignFixedRegisters
2412 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2414 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2415 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2416 variables in unused register banks. Also the SSEG is placed
2417 wherever there is enough space for it, and IDATA can be anywhere
2418 in internal RAM. For now compile using -Wl-Y[stack_size].
2419 The mem file is different for this option as well, since it
2420 makes no sense of talking about DSEG lenght.
2422 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2424 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2425 in certain cases, e.g. when ROM assignment, patch provided
2426 from Albert den Haan.

2669 * src/SDCCast.c (decorateType): disabled a transformation I added in
2670 revision 1.188 (access to fields of a structure at an absolute address);
2671 it breaks with bitfields, extern declarations, and gcse analysis.
2672 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2673 could be assigned through a pointer, so don't complain.
2674 * src/SDCCast.c (astErrors),
2676 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

2778 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
2779 uninitialized variables) for the mcs51. Set environment variable
2780 SDCC_GENRAMCLEAR to test.
2781 xdata initialization slightly shorter
2783 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3429 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3430 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3431 fetching of the pointer
3432 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3433 copied from genNearPointerSet()
3434 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3435 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3451 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3452 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3453 type for bits was changed. It resulted in bit variables becoming
3454 global, which is not permitted in PIC 14 assembly output.
3456 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3458 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3471 A few small changes that speed up the peephole optimizer.
3475 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3477 Try to make the peephole optimizer smarter by maintaining
3478 an association between the assembly source code and the
3479 iCodes that originated them. Put this information to use
3480 with a new peephole rule condition "notVolatile" so that
3481 the rules can be aggressive yet still safe.
3486 * src/mcs51/peeph.def
3488 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3492 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3493 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3494 if the left or right operand symbols have the accuse flag set.
3496 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3498 Changed the type of the result of the ! (NOT) operator to char;
3499 previously it returned the same type as the source. This allows
3500 us to eliminate all the genFloatNot functions (all of its target
3501 implementations were very buggy) since !float can use the same
3504 * src/SDCCicode.c (ast2iCode): ! returns char

3513 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3514 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3515 during interrupts. Ensure WSAVE is located at a shared bank address.
3516 2. Fixed page selection in some places
3517 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3518 the registers name strings.
3519 4. Fixed "signed / unsigned compare" compiler warnings.
3520 5. The PIC port manages its own allocation of the general purpose
3521 registers, but makes no attempt to reuse them. As a result when
3522 compiling it soon runs out of general purpose registers. Some
3523 additional code was added to the files pcode.c and device.c to walk
3524 through the function call tree and rename the registers so that they
3534 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3535 genPlus() & genMinus() when the result is the same as left or right

3541 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3543 Made bitfield a distinct type from bit so that bitfields
3544 convert as per ANSI C and bits retain their traditional
3545 boolean style behaviour. Implemented bitfield support in
3553 * src/ds390/gen.c: bit v bitfield split
3554 * src/z80/gen.c: New support for bitfields
3555 * support/regression/tests/bitfields.c: reenabled z80,
3558 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3560 Rules 246.x, 247.x relate to bitfields, the others speed up
3561 access to xdata mapped I/O devices.
3563 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3565 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3567 Cleaned up genPackBits and genUnpackBits and added two helper
3568 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3569 for literal assignments in genPackBits (thanks to Frieder for
3575 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3577 Fixed bug #748310 (pointer to function type mishandled when the
3578 function name is omitted). Also fixed a SIGSEGV when a function
3579 attribute (reentrant, etc) is used on a non-function or on a
3580 function but misplaced before the parameter list.
3582 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3584 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3585 * support/Util/SDCCerr.h,
3586 * support/Util/SDCCerr.c: Added func attr misuse error msg
3588 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3590 Fixed bug #787649 by anonymous
3591 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

3607 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3609 Made the constant following the "interrupt" keyword optional. If
3610 omitted, the function will not automatically be given an entry
3611 in the interrupt vector table (similar to #pragma NOIV, but
3612 less syntacticly kludgy). The interrupt number is also now
3613 range checked. Also fixed a bug in the high order bit example

3621 * support/Util/SDCCerr.h
3624 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3626 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
3627 * src/SDCCicode.c (operandOperation): rewritten some ops
3628 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3629 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3631 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3632 be re-activated by defining REDUCE_LITERALS)
3633 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3634 unsigned, but are signed by default
3635 * src/SDCCval.c (constVal): rearranged
3636 * src/SDCCval.c (valMod): preliminary fix
3637 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3679 constants are unsigned; added recognition of "u" flag for unsigned
3680 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3681 * src/SDCCval.c (valDiv, valMod): fixed signdness
3682 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3683 signedness of modulo, left and right shift

4142 * src/SDCCmain.c: linkOptions is changed to set *,
4143 added if/endif conditional macros to remove options help
4144 messages from optionsTable when a port is not configured, added
4145 support for the PIc16 port in the ports table, when executing
4146 the compiler with no port specified on command line, a default
4147 port is selected with the new macro DEFAULT_PORT which is
4148 defined in port.h, in setDefaultOptions() linkOptions is removed
4149 from initialization assignment, since now it is a set,
4150 parseCmdLine uses setParseWithComma for linkOptions, in
4151 linkEdit() linkOptions are accessed with new function indexSet()
4152 which returns the i'th item of a set variable. See SDCCset.c, in
4153 linkEdit() when calling buildCmdLine(), added linkOptions as
4154 last argument. Now users can pass arguments to gplink via the
4155 -Wl option, main() uses pic16glue() to glue up pic16 programs

4168 * src/pic16/main.c: __config directives are commented out to stop
4169 gpasm complaining and test the linkage with gplink, _linkCmd and
4170 _asmCmd changed to be more gplink and gpasm friendly
4171 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4172 produced an error when parsed, peep rule 12 is added to utilize
4173 movff, but it is commented out since the pCode does not support
4174 yet a command with 2 address arguments
4176 2003-05-18 <johan AT balder>
4178 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4205 2003-05-11 Borut Razem <borut.razem AT siol.net>
4207 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4208 the path of bin directory, so that PATH is the only env. variable, which has to be set
4209 in case of standard installation.

5242 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5243 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5244 following files to include the previous two files: aslink.dsp,
5245 Makefile.aslink, Makefile.bcc, and Makefile.in.
5247 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5248 .adb instead of .cdb
5250 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5252 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5253 value from option --iram-size.
5255 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5257 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5260 2002-09-18 <wiml AT hhhh.org>
5262 * SDCClrange.h: exposed setFromRange() and setToRange()
5263 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5264 packRegsForAccUse() (bug 542397)
5265 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5266 multiple times and emitting the fetch operations more than once
5267 added aopGetUsesAcc() function to allow binary operators to
5268 fetch their operands in the correct order; made genMinus() emit
5269 compact code for X = LITERAL - Y
5271 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5272 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5273 sprintf() in line 1267.
5275 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5276 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5279 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5280 Changes to aslink (All the changes are marked with 'JCF'):
5282 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5285 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5286 area BSEG. Also moves, if possible, the DATA area down into the internal
5287 ram so more space is available.
5289 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5292 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5293 not bytes. Function summary() which creates a memory usage summary
5294 file with extension .mem. Reports of overlaping stack and small stack
5295 size. If the space for the stack is less than 16 bytes aslink trows a
5298 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5299 the 8051. Option 'y' for memory summary output file.
5301 Changes to sdcc (All the changes are marked with 'JCF'):
5303 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5305 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5306 overlaying area for it (uses RegBankUsed[4]).
5308 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5309 bank zero as used by default. By default aslink locates the stack
5310 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5311 the creation of the .mem file. Delegates the allocation of data area
5312 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5313 the begining of the stack area to aslink.
5315 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5316 glue() in SDCCglue.c creates an area for it.
5318 2002-09-03 Borut Razem <borut.razem AT siol.net>
5319 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5320 sdcc/src/pic/glue.c:
5321 introduced atexit() handler for teporay files removal in case of
5322 errors, assertions, ...
5324 2002-08-29 Borut Razem <borut.razem AT siol.net>
5325 * sdcc/support/cpp2/auto-host_vc_in.h:
5326 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5327 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5328 Maybe there is a similar problem with BORLANDC? It should be checked!
5330 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5331 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5332 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5333 was not executed, and the compiler (cl) launched a warning:
5334 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5336 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5337 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5339 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5340 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5342 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5343 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5344 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5345 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5346 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5347 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5348 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5349 - added Release configuration in VS projects
5350 - review of compiler an linker options
5351 - VC .exe files are generated in bin_vc directory, not to interfere
5352 with binaries generated from other projects (cygwin, mingw, bcc ...)
5354 * sdcc/src/yacc.dsp: added
5356 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5357 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5358 and insert the version number definitions from .version
5360 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5362 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5363 added - genarate auto-host.h using auto-host_vc_in.h as template
5366 removed from CVS, generated automatically
5368 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5369 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5371 2002-08-11 Borut Razem <borut.razem AT siol.net>
5372 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5374 2002-08-10 Borut Razem <borut.razem AT siol.net>
5375 * src/SDCCmain.c (main):
5376 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5377 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5378 The consequence was that some temporary files were not removed.
5381 unification of code in functions tempfilename() and tempfile():
5382 function tempnam() is defined in Visual Studio 6.0 and .NET
5384 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5386 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5387 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5388 - removed compiler command line option /WX: Treats all warnings as errors
5389 - update a list of source files, included into the project
5391 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5392 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5393 changed project type to Generic Project so that can be correcly converted to VS.NET project
5395 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5397 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5399 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5401 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5402 added return 0 statements after assert() to make compiler happy
5404 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5405 added newline in the def file to keep MSC compiler satisfied
5407 * sdcc/src/z80/gen.c:
5408 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5409 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5410 - solved MSC error in function aopDump()
5412 * sdcc_vc.h: define PREFIX as "\\sdcc"
5414 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5415 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5417 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5418 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5419 - Rewrote the register banking algorithm.
5420 - Added pCode live-range analysis to registers (for now, only non-used and
5421 singly-used registers optimized away)
5423 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5425 * 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.

5452 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5454 2002-03-28 Johan Knol <johan AT balder>
5456 * src/SDCCval.c: fixed bug #532436
5458 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5460 Added "char *Processor" field to the port structure.
5463 Added -p option. Allows port dependent processor to be specified.
5466 Initialized the new field char *Processor field to NULL in all ports
5469 Compiler generated registers for interrupt context saving
5470 were not getting allocated.
5472 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5475 Fixed left shift. Will promote the left side of a left shift
5476 if a) left shifting more than size of operand or b) when assigned
5477 to something size > size of left side
5479 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5481 tons of changes. Register allocation has been
5482 rewritten. Added customization for the various PICs. Flow
5483 analysis is restructured. ...
5489 Added. device.c is a PIC port hack to accomodate variations
5492 2002-03-13 Michael Hope <michaelh AT vroom>
5494 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

5587 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5589 * sdcc/src/SDCCloop.c:
5590 Previous fix was not good. basic blocks that have "break" or "return" are
5591 not really partof a loop , but live ranges used in these blocks should
5592 be live thru the entire loop, so set partOfLoop but don't add them to
5595 2002-02-21 <johan AT FRIJA>
5597 * src/SDCCcse.c: fixed bug #514308
5599 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5603 statement inside a loop, it was not being considered part of the loop.
5605 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5607 2002-02-10 Karl Bongers <karl AT turbobit.com>
5610 Fixed up SDCDB debugger somewhat. Updated debugger/README
5611 with lots of comments and notes.
5613 * device/examples/test2.c:
5614 Fix bug, "red" variable not being initialized(compiler complained).

5620 * sim/ucsim/cmd.src/cmdset.cc:
5621 Took out debug printfs in ucsim "next" command.
5624 Karl and Johan start ucsim XA support. Most dissassembly working,
5625 about 75% emulation done(plenty of work remaining).
5627 * sim/ucsim/z80.src:
5628 Add Z80 support to ucsim, add test-ucz80 regression test,
5629 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

5665 set preprocessor defines (depending on options)
5667 * src/SDCCicode.c, src/SDCCicode.h:
5668 changes made to handle multiple sends & receives
5671 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
