1867 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1869 * src/SDCCast.c: added an additional type flow in decorateType() of
1870 opposite direction, see feature request #860006; it's enabled at runtime
1871 by setting the environment variable SDCC_NEWTYPEFLOW
1872 * src/SDCCast.h: changed prototype of decorateType()
1873 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1874 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

1906 added support for multiple code pages and multiple RAM banks on the
1907 PIC 14 port. The ASM files now no longer simply assume all the
1908 code / RAM are in the same page / bank. This means the linker can
1909 safely allocate code/RAM of separate ASM files to different pages/banks.
1910 * doc/sdccman.lyx: added Slade's tips
1911 * src/mcs51/peeph.def: fixed bug #880768

1953 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1955 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1956 loaded with the linker search paths (-L arguments) and the libraries
1957 to be linked with the current source (-l arguments). Changes
1958 currently will affect only the pic16 port.
1959 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1960 include path the port specific paths and port specific libraries,
1961 * gplink command now contains the $3 argument,
1962 * src/pic16/device.h,
1963 * src/pic16/device.c,: structure PIC_device is made public and
1964 renamed to PIC16_device, the same for variable Pics which is renamed

1979 Documenting changes from previous commits.
1980 * configure.in (version 1.56),
1981 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1982 when generating output files to configure the pic16 library,
1983 but now I've commented it out, since gputils aren't installed in the
1984 SF compile farm, so library won't compile
1986 * device/lib/Makefile.in (version 1.56): initially I've added in
1987 target 'all' the prerequestive 'model-pic16' so it compiled the
1988 pic16 library, but now I've commented it out for the same reasons
1990 * added targets 'model-pic16' and 'objects-pic16' to compile the
1992 * added target 'port-specific-objects-pic16' to handle the
1993 generated libraries and copy them into the build/ directory
1994 * added target 'clean-intermediate-pic16' to clean intermediate
1995 files into pic16 directory
1996 * in target 'installdirs' added line to create directory pic16 in

2050 data are now emitted in sorted order to reduce section naming,
2051 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2052 weren't marked as being in the access bank,

2294 pushing/retrieving function parameters to/from stack,
2295 genFunction,genEndFunction: setup stack frame for the
2297 genAddrOf: will be changed according to bug 863624
2299 * added files genutils.c and genutils.h which contain gen*
2300 debugged and optimised functions extracted from gen.c
2302 * glue.c: added variable 'externs' which holds extern symbols,
2303 pic16emitRegularMap: is modified to properly handle relocatable
2304 symbols under the new scheme,
2305 pic16createInterruptVect: is modified
2306 pic16printPublics: is modified to emit 'global' assembler directives,

2311 yet support a type of crt0.o object to create the final binary.
2313 * Removed many lines that contain 8051 legacy code.
2314 * The code is finally placed under a 'code' directive.
2315 * Added port specific options.
2317 * _process_pragma: simplified since now we do not need *special*
2318 include file to define SFR registers. But a separate header
2319 will be needed. This will be developed later.
2320 * _pic16_parseOptions: added, parses port specific options:
2321 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2322 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2323 --preplace-udata-with=
2325 * _pic16_setDefaultOptions: modified to initialize section names,
2326 but hack is temporarly out of order since it needs improvement.
2327 * _pic16_genAssemblerPreamble: configuration words are emitted by
2328 their address instead of their name. This part is incomplete and
2329 supports only the 18Fxx2 devices. Other devices will emit an error
2330 during assembly since they do not contain the same set of config
2332 * _pic16_genIVT: is modified,
2334 * pcode.c: added definitions for some hardware registers that are needed
2336 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2337 All PCI entries are updated. Now LFSR is supported.
2338 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2339 * added pic16_newpCodeOpLit2 to support instructions with
2340 two literal arguments
2341 * pic16_pCode2str: corrected code that emits assembler instructions
2342 with two literal operands and those that have an access bit modifier
2343 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2344 this fixes a bug which caused some labels to be lost, when an
2345 assembler directive was added, i.e. banksel,
2346 * pic16_FixRegisterBanking: improved logic that causes the insertion
2348 * InlineFunction: functions that are called once, are not any more
2349 inlined. This can be a port option in the future,
2351 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2353 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2354 hold the corresponding uninitialized symbols,
2355 * pic16_allocProcessorRegister: registers have explicit marked the
2357 * pic16_allocInternalRegister: registers are explicit marked as
2359 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2360 processing list, so bit registers were lost,
2363 * ralloc.h: added field 'accessBank' and original symbol operand
2364 in register definition,
2365 * removed the field isMapped from register definition,
2367 ** Several functions have been removed from various sources:
2368 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2369 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2370 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2371 pic16_assignRelocatableRegisters
2373 ** others have been introduced:
2374 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2375 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2377 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2379 * support/scripts/inc2h.pl: changed definition of BIT_AT
2380 to emit 'sbit at' instead of 'bit at'. This was a request.
2382 PIC16 port related preliminary changes:
2383 * gen.c: prefixed function popRegFromString with
2384 pic16_ and all references to it corrected
2385 * pcode.c: all pic16_pc_* hardware registers prefixed
2386 with underscore (_),
2387 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2388 * ralloc.c: newReg(): when register is REG_SFR then
2389 set address to rIdx,
2390 pic16_allocProcessorRegister(): marks register wasUsed=0
2391 pic16_writeUsedRegs(): added a call to assign processor
2392 registers via pic16_assignFixedRegisters
2394 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2396 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2397 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2398 variables in unused register banks. Also the SSEG is placed
2399 wherever there is enough space for it, and IDATA can be anywhere
2400 in internal RAM. For now compile using -Wl-Y[stack_size].
2401 The mem file is different for this option as well, since it
2402 makes no sense of talking about DSEG lenght.
2404 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2406 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2407 in certain cases, e.g. when ROM assignment, patch provided
2408 from Albert den Haan.

2651 * src/SDCCast.c (decorateType): disabled a transformation I added in
2652 revision 1.188 (access to fields of a structure at an absolute address);
2653 it breaks with bitfields, extern declarations, and gcse analysis.
2654 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2655 could be assigned through a pointer, so don't complain.
2656 * src/SDCCast.c (astErrors),

2763 xdata initialization slightly shorter
2765 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3433 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3434 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3435 type for bits was changed. It resulted in bit variables becoming

3453 A few small changes that speed up the peephole optimizer.
3457 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3459 Try to make the peephole optimizer smarter by maintaining
3460 an association between the assembly source code and the
3461 iCodes that originated them. Put this information to use
3462 with a new peephole rule condition "notVolatile" so that
3463 the rules can be aggressive yet still safe.
3468 * src/mcs51/peeph.def
3470 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3474 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3475 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3476 if the left or right operand symbols have the accuse flag set.
3478 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3480 Changed the type of the result of the ! (NOT) operator to char;
3481 previously it returned the same type as the source. This allows
3482 us to eliminate all the genFloatNot functions (all of its target
3483 implementations were very buggy) since !float can use the same
3486 * src/SDCCicode.c (ast2iCode): ! returns char

3495 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3496 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3497 during interrupts. Ensure WSAVE is located at a shared bank address.
3498 2. Fixed page selection in some places
3499 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3500 the registers name strings.
3501 4. Fixed "signed / unsigned compare" compiler warnings.
3502 5. The PIC port manages its own allocation of the general purpose
3503 registers, but makes no attempt to reuse them. As a result when
3504 compiling it soon runs out of general purpose registers. Some
3505 additional code was added to the files pcode.c and device.c to walk
3506 through the function call tree and rename the registers so that they
3516 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3523 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3525 Made bitfield a distinct type from bit so that bitfields
3526 convert as per ANSI C and bits retain their traditional
3527 boolean style behaviour. Implemented bitfield support in
3535 * src/ds390/gen.c: bit v bitfield split
3536 * src/z80/gen.c: New support for bitfields
3537 * support/regression/tests/bitfields.c: reenabled z80,
3540 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3542 Rules 246.x, 247.x relate to bitfields, the others speed up
3543 access to xdata mapped I/O devices.
3545 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3547 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3549 Cleaned up genPackBits and genUnpackBits and added two helper
3550 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3551 for literal assignments in genPackBits (thanks to Frieder for
3557 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3559 Fixed bug #748310 (pointer to function type mishandled when the
3560 function name is omitted). Also fixed a SIGSEGV when a function
3561 attribute (reentrant, etc) is used on a non-function or on a
3562 function but misplaced before the parameter list.
3564 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3566 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3589 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3591 Made the constant following the "interrupt" keyword optional. If
3592 omitted, the function will not automatically be given an entry
3593 in the interrupt vector table (similar to #pragma NOIV, but
3594 less syntacticly kludgy). The interrupt number is also now
3595 range checked. Also fixed a bug in the high order bit example

3609 * src/SDCCicode.c (operandOperation): rewritten some ops
3610 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3611 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3613 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3614 be re-activated by defining REDUCE_LITERALS)
3615 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3616 unsigned, but are signed by default
3617 * src/SDCCval.c (constVal): rearranged
3618 * src/SDCCval.c (valMod): preliminary fix
3619 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4124 * src/SDCCmain.c: linkOptions is changed to set *,
4125 added if/endif conditional macros to remove options help
4126 messages from optionsTable when a port is not configured, added
4127 support for the PIc16 port in the ports table, when executing
4128 the compiler with no port specified on command line, a default
4129 port is selected with the new macro DEFAULT_PORT which is
4130 defined in port.h, in setDefaultOptions() linkOptions is removed
4131 from initialization assignment, since now it is a set,
4132 parseCmdLine uses setParseWithComma for linkOptions, in
4133 linkEdit() linkOptions are accessed with new function indexSet()
4134 which returns the i'th item of a set variable. See SDCCset.c, in
4135 linkEdit() when calling buildCmdLine(), added linkOptions as
4136 last argument. Now users can pass arguments to gplink via the
4137 -Wl option, main() uses pic16glue() to glue up pic16 programs

4149 * src/pic16/glue.c: commented out some error producing lines
4150 * src/pic16/main.c: __config directives are commented out to stop
4151 gpasm complaining and test the linkage with gplink, _linkCmd and
4152 _asmCmd changed to be more gplink and gpasm friendly
4153 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4154 produced an error when parsed, peep rule 12 is added to utilize
4155 movff, but it is commented out since the pCode does not support
4156 yet a command with 2 address arguments
4158 2003-05-18 <johan AT balder>
4160 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4187 2003-05-11 Borut Razem <borut.razem AT siol.net>
4189 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4190 the path of bin directory, so that PATH is the only env. variable, which has to be set
4191 in case of standard installation.
4192 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5235 value from option --iram-size.
5237 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5239 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5242 2002-09-18 <wiml AT hhhh.org>
5244 * SDCClrange.h: exposed setFromRange() and setToRange()
5245 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5246 packRegsForAccUse() (bug 542397)
5247 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5248 multiple times and emitting the fetch operations more than once
5249 added aopGetUsesAcc() function to allow binary operators to
5250 fetch their operands in the correct order; made genMinus() emit
5251 compact code for X = LITERAL - Y
5253 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5254 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5255 sprintf() in line 1267.
5257 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5258 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5261 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5262 Changes to aslink (All the changes are marked with 'JCF'):
5264 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5267 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5268 area BSEG. Also moves, if possible, the DATA area down into the internal
5269 ram so more space is available.
5271 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5274 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5275 not bytes. Function summary() which creates a memory usage summary
5276 file with extension .mem. Reports of overlaping stack and small stack
5277 size. If the space for the stack is less than 16 bytes aslink trows a
5280 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5281 the 8051. Option 'y' for memory summary output file.
5283 Changes to sdcc (All the changes are marked with 'JCF'):
5285 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5287 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5288 overlaying area for it (uses RegBankUsed[4]).
5290 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5291 bank zero as used by default. By default aslink locates the stack
5292 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5293 the creation of the .mem file. Delegates the allocation of data area
5294 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5295 the begining of the stack area to aslink.
5297 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5298 glue() in SDCCglue.c creates an area for it.
5300 2002-09-03 Borut Razem <borut.razem AT siol.net>
5301 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5302 sdcc/src/pic/glue.c:
5303 introduced atexit() handler for teporay files removal in case of
5304 errors, assertions, ...
5306 2002-08-29 Borut Razem <borut.razem AT siol.net>
5307 * sdcc/support/cpp2/auto-host_vc_in.h:
5308 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5309 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5310 Maybe there is a similar problem with BORLANDC? It should be checked!
5312 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5313 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5314 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5315 was not executed, and the compiler (cl) launched a warning:
5316 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5318 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5319 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5321 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5322 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5324 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5325 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5326 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5327 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5328 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5329 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5330 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5331 - added Release configuration in VS projects
5332 - review of compiler an linker options
5333 - VC .exe files are generated in bin_vc directory, not to interfere
5334 with binaries generated from other projects (cygwin, mingw, bcc ...)
5336 * sdcc/src/yacc.dsp: added
5338 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5339 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5340 and insert the version number definitions from .version
5342 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5344 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5345 added - genarate auto-host.h using auto-host_vc_in.h as template
5348 removed from CVS, generated automatically
5350 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5351 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5353 2002-08-11 Borut Razem <borut.razem AT siol.net>
5354 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5356 2002-08-10 Borut Razem <borut.razem AT siol.net>
5357 * src/SDCCmain.c (main):
5358 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5359 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5360 The consequence was that some temporary files were not removed.
5363 unification of code in functions tempfilename() and tempfile():
5364 function tempnam() is defined in Visual Studio 6.0 and .NET
5366 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5368 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5369 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5370 - removed compiler command line option /WX: Treats all warnings as errors
5371 - update a list of source files, included into the project
5373 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5374 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5375 changed project type to Generic Project so that can be correcly converted to VS.NET project
5377 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5379 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5381 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5383 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5384 added return 0 statements after assert() to make compiler happy
5386 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5387 added newline in the def file to keep MSC compiler satisfied
5389 * sdcc/src/z80/gen.c:
5390 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5391 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5392 - solved MSC error in function aopDump()
5394 * sdcc_vc.h: define PREFIX as "\\sdcc"
5396 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5397 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5400 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5401 - Rewrote the register banking algorithm.
5402 - Added pCode live-range analysis to registers (for now, only non-used and
5403 singly-used registers optimized away)
5405 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

5436 2002-03-28 Johan Knol <johan AT balder>
5438 * src/SDCCval.c: fixed bug #532436
5440 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5442 Added "char *Processor" field to the port structure.
5445 Added -p option. Allows port dependent processor to be specified.
5448 Initialized the new field char *Processor field to NULL in all ports
5451 Compiler generated registers for interrupt context saving
5452 were not getting allocated.
5454 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5457 Fixed left shift. Will promote the left side of a left shift
5458 if a) left shifting more than size of operand or b) when assigned
5459 to something size > size of left side
5461 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5463 tons of changes. Register allocation has been
5464 rewritten. Added customization for the various PICs. Flow

5569 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5571 * sdcc/src/SDCCloop.c:
5572 Previous fix was not good. basic blocks that have "break" or "return" are
5573 not really partof a loop , but live ranges used in these blocks should
5574 be live thru the entire loop, so set partOfLoop but don't add them to
5577 2002-02-21 <johan AT FRIJA>
5579 * src/SDCCcse.c: fixed bug #514308
5581 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
5584 Fixed BUG #519583. If a conditional block ended in a return/break
5585 statement inside a loop, it was not being considered part of the loop.
5587 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5589 2002-02-10 Karl Bongers <karl AT turbobit.com>
5592 Fixed up SDCDB debugger somewhat. Updated debugger/README
5593 with lots of comments and notes.
5595 * device/examples/test2.c:
5596 Fix bug, "red" variable not being initialized(compiler complained).
5598 * device/examples/Makefile, examples/test3.c:

5600 for use as a multiple module SDCDB test case.
5602 * sim/ucsim/cmd.src/cmdset.cc:
5603 Took out debug printfs in ucsim "next" command.
5606 Karl and Johan start ucsim XA support. Most dissassembly working,
5607 about 75% emulation done(plenty of work remaining).
5609 * sim/ucsim/z80.src:
5610 Add Z80 support to ucsim, add test-ucz80 regression test,
5611 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

5647 set preprocessor defines (depending on options)
5649 * src/SDCCicode.c, src/SDCCicode.h:
5650 changes made to handle multiple sends & receives
5653 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
