625 Adding support for replacing ljmps with sjmps in jumptables
626 generated for switch statements. For now you need to set the
627 environment variable SDCC_SJMP_JUMPTABLE to enable this.
628 Now 4 algorithms for mcs51 jumptable generation are used:
629 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

663 * added libc directory. The current version of LibC contains string
664 functions, ctype functions and macros and some functions of the
665 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
666 be extensively tested in the future. Standard disclaimer here.
667 Library is not automatically build yet. But one can build it by

680 * (genCmp): experimental code for new genCmp which uses PIC18's
681 special compare&skip instructions. Initial tests fail some times
682 with variables grater than 1 byte in size, so new code is disabled,
683 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
685 * (genCast): began a fix to optimize the casting of a bit to another
686 bit, now assigning a bitfield to another bitfield will fail, sorry,

3712 loaded with the linker search paths (-L arguments) and the libraries
3713 to be linked with the current source (-l arguments). Changes
3714 currently will affect only the pic16 port.
3715 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3716 include path the port specific paths and port specific libraries,
3717 * gplink command now contains the $3 argument,
3718 * src/pic16/device.h,

3735 Documenting changes from previous commits.
3736 * configure.in (version 1.56),
3737 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3738 when generating output files to configure the pic16 library,
3739 but now I've commented it out, since gputils aren't installed in the
3740 SF compile farm, so library won't compile
3742 * device/lib/Makefile.in (version 1.56): initially I've added in
3743 target 'all' the prerequestive 'model-pic16' so it compiled the
3744 pic16 library, but now I've commented it out for the same reasons
3746 * added targets 'model-pic16' and 'objects-pic16' to compile the
3748 * added target 'port-specific-objects-pic16' to handle the
3749 generated libraries and copy them into the build/ directory
3750 * added target 'clean-intermediate-pic16' to clean intermediate
3751 files into pic16 directory
3752 * in target 'installdirs' added line to create directory pic16 in

4063 added pic16_printExterns to print extern symbols,
4064 pic16glue: initializes stack/frame pointer in the beginning of
4065 the assembly output. Temporary hack, will be corrected later,
4066 because gplink yet does not support stack and SDCC does not
4067 yet support a type of crt0.o object to create the final binary.
4069 * Removed many lines that contain 8051 legacy code.
4070 * The code is finally placed under a 'code' directive.
4071 * Added port specific options.
4073 * _process_pragma: simplified since now we do not need *special*
4074 include file to define SFR registers. But a separate header
4075 will be needed. This will be developed later.
4076 * _pic16_parseOptions: added, parses port specific options:
4077 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4078 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4079 --preplace-udata-with=
4081 * _pic16_setDefaultOptions: modified to initialize section names,
4082 but hack is temporarly out of order since it needs improvement.
4083 * _pic16_genAssemblerPreamble: configuration words are emitted by
4084 their address instead of their name. This part is incomplete and
4085 supports only the 18Fxx2 devices. Other devices will emit an error
4086 during assembly since they do not contain the same set of config
4088 * _pic16_genIVT: is modified,
4090 * pcode.c: added definitions for some hardware registers that are needed
4092 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4093 All PCI entries are updated. Now LFSR is supported.
4094 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4095 * added pic16_newpCodeOpLit2 to support instructions with
4096 two literal arguments
4097 * pic16_pCode2str: corrected code that emits assembler instructions
4098 with two literal operands and those that have an access bit modifier
4099 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4100 this fixes a bug which caused some labels to be lost, when an
4101 assembler directive was added, i.e. banksel,
4102 * pic16_FixRegisterBanking: improved logic that causes the insertion
4104 * InlineFunction: functions that are called once, are not any more
4105 inlined. This can be a port option in the future,
4107 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4109 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4110 hold the corresponding uninitialized symbols,
4111 * pic16_allocProcessorRegister: registers have explicit marked the
4113 * pic16_allocInternalRegister: registers are explicit marked as
4115 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4116 processing list, so bit registers were lost,
4119 * ralloc.h: added field 'accessBank' and original symbol operand
4120 in register definition,
4121 * removed the field isMapped from register definition,
4123 ** Several functions have been removed from various sources:
4124 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4125 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4126 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4127 pic16_assignRelocatableRegisters
4129 ** others have been introduced:
4130 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4131 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4133 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4135 * support/scripts/inc2h.pl: changed definition of BIT_AT
4136 to emit 'sbit at' instead of 'bit at'. This was a request.
4138 PIC16 port related preliminary changes:
4139 * gen.c: prefixed function popRegFromString with
4140 pic16_ and all references to it corrected
4141 * pcode.c: all pic16_pc_* hardware registers prefixed
4142 with underscore (_),
4143 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4144 * ralloc.c: newReg(): when register is REG_SFR then
4145 set address to rIdx,
4146 pic16_allocProcessorRegister(): marks register wasUsed=0
4147 pic16_writeUsedRegs(): added a call to assign processor
4148 registers via pic16_assignFixedRegisters
4150 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4152 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4153 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4154 variables in unused register banks. Also the SSEG is placed
4155 wherever there is enough space for it, and IDATA can be anywhere
4156 in internal RAM. For now compile using -Wl-Y[stack_size].
4157 The mem file is different for this option as well, since it
4158 makes no sense of talking about DSEG lenght.
4160 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4162 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4163 in certain cases, e.g. when ROM assignment, patch provided
4164 from Albert den Haan.

4407 * src/SDCCast.c (decorateType): disabled a transformation I added in
4408 revision 1.188 (access to fields of a structure at an absolute address);
4409 it breaks with bitfields, extern declarations, and gcse analysis.
4410 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4411 could be assigned through a pointer, so don't complain.
4412 * src/SDCCast.c (astErrors),
4414 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4516 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4517 uninitialized variables) for the mcs51. Set environment variable
4518 SDCC_GENRAMCLEAR to test.
4519 xdata initialization slightly shorter
4521 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5170 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5171 copied from genNearPointerSet()
5172 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5173 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5189 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5190 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5191 type for bits was changed. It resulted in bit variables becoming
5192 global, which is not permitted in PIC 14 assembly output.

5209 A few small changes that speed up the peephole optimizer.
5213 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5215 Try to make the peephole optimizer smarter by maintaining
5216 an association between the assembly source code and the
5217 iCodes that originated them. Put this information to use
5218 with a new peephole rule condition "notVolatile" so that
5219 the rules can be aggressive yet still safe.
5224 * src/mcs51/peeph.def
5226 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5230 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

5232 if the left or right operand symbols have the accuse flag set.
5234 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5236 Changed the type of the result of the ! (NOT) operator to char;
5237 previously it returned the same type as the source. This allows
5238 us to eliminate all the genFloatNot functions (all of its target
5239 implementations were very buggy) since !float can use the same

5251 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5252 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5253 during interrupts. Ensure WSAVE is located at a shared bank address.
5254 2. Fixed page selection in some places
5255 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5256 the registers name strings.
5257 4. Fixed "signed / unsigned compare" compiler warnings.
5258 5. The PIC port manages its own allocation of the general purpose
5259 registers, but makes no attempt to reuse them. As a result when
5260 compiling it soon runs out of general purpose registers. Some
5261 additional code was added to the files pcode.c and device.c to walk
5262 through the function call tree and rename the registers so that they
5272 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5279 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5281 Made bitfield a distinct type from bit so that bitfields
5282 convert as per ANSI C and bits retain their traditional
5283 boolean style behaviour. Implemented bitfield support in
5291 * src/ds390/gen.c: bit v bitfield split
5292 * src/z80/gen.c: New support for bitfields
5293 * support/regression/tests/bitfields.c: reenabled z80,
5296 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5298 Rules 246.x, 247.x relate to bitfields, the others speed up
5299 access to xdata mapped I/O devices.
5301 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5303 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5305 Cleaned up genPackBits and genUnpackBits and added two helper
5306 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5307 for literal assignments in genPackBits (thanks to Frieder for
5313 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5315 Fixed bug #748310 (pointer to function type mishandled when the
5316 function name is omitted). Also fixed a SIGSEGV when a function
5317 attribute (reentrant, etc) is used on a non-function or on a
5318 function but misplaced before the parameter list.
5320 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5322 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5323 * support/Util/SDCCerr.h,

5345 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5347 Made the constant following the "interrupt" keyword optional. If
5348 omitted, the function will not automatically be given an entry
5349 in the interrupt vector table (similar to #pragma NOIV, but
5350 less syntacticly kludgy). The interrupt number is also now
5351 range checked. Also fixed a bug in the high order bit example

5365 * src/SDCCicode.c (operandOperation): rewritten some ops
5366 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5367 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5369 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5370 be re-activated by defining REDUCE_LITERALS)
5371 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5372 unsigned, but are signed by default
5373 * src/SDCCval.c (constVal): rearranged
5374 * src/SDCCval.c (valMod): preliminary fix
5375 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5880 * src/SDCCmain.c: linkOptions is changed to set *,
5881 added if/endif conditional macros to remove options help
5882 messages from optionsTable when a port is not configured, added
5883 support for the PIc16 port in the ports table, when executing
5884 the compiler with no port specified on command line, a default
5885 port is selected with the new macro DEFAULT_PORT which is
5886 defined in port.h, in setDefaultOptions() linkOptions is removed
5887 from initialization assignment, since now it is a set,
5888 parseCmdLine uses setParseWithComma for linkOptions, in
5889 linkEdit() linkOptions are accessed with new function indexSet()
5890 which returns the i'th item of a set variable. See SDCCset.c, in
5891 linkEdit() when calling buildCmdLine(), added linkOptions as
5892 last argument. Now users can pass arguments to gplink via the
5893 -Wl option, main() uses pic16glue() to glue up pic16 programs

5907 gpasm complaining and test the linkage with gplink, _linkCmd and
5908 _asmCmd changed to be more gplink and gpasm friendly
5909 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5910 produced an error when parsed, peep rule 12 is added to utilize
5911 movff, but it is commented out since the pCode does not support
5912 yet a command with 2 address arguments
5914 2003-05-18 <johan AT balder>
5916 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5943 2003-05-11 Borut Razem <borut.razem AT siol.net>
5945 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5946 the path of bin directory, so that PATH is the only env. variable, which has to be set
5947 in case of standard installation.

6980 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6981 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6982 following files to include the previous two files: aslink.dsp,
6983 Makefile.aslink, Makefile.bcc, and Makefile.in.
6985 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6986 .adb instead of .cdb
6988 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6990 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6991 value from option --iram-size.
6993 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6995 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6998 2002-09-18 <wiml AT hhhh.org>
7000 * SDCClrange.h: exposed setFromRange() and setToRange()
7001 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7002 packRegsForAccUse() (bug 542397)
7003 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7004 multiple times and emitting the fetch operations more than once
7005 added aopGetUsesAcc() function to allow binary operators to
7006 fetch their operands in the correct order; made genMinus() emit
7007 compact code for X = LITERAL - Y
7009 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7010 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7011 sprintf() in line 1267.
7013 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7014 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7017 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7018 Changes to aslink (All the changes are marked with 'JCF'):
7020 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7023 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7024 area BSEG. Also moves, if possible, the DATA area down into the internal
7025 ram so more space is available.
7027 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7030 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7031 not bytes. Function summary() which creates a memory usage summary
7032 file with extension .mem. Reports of overlaping stack and small stack
7033 size. If the space for the stack is less than 16 bytes aslink trows a
7036 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7037 the 8051. Option 'y' for memory summary output file.
7039 Changes to sdcc (All the changes are marked with 'JCF'):
7041 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7043 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7044 overlaying area for it (uses RegBankUsed[4]).
7046 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7047 bank zero as used by default. By default aslink locates the stack
7048 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7049 the creation of the .mem file. Delegates the allocation of data area
7050 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7051 the begining of the stack area to aslink.
7053 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7054 glue() in SDCCglue.c creates an area for it.
7056 2002-09-03 Borut Razem <borut.razem AT siol.net>
7057 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7058 sdcc/src/pic/glue.c:
7059 introduced atexit() handler for teporay files removal in case of
7060 errors, assertions, ...
7062 2002-08-29 Borut Razem <borut.razem AT siol.net>
7063 * sdcc/support/cpp2/auto-host_vc_in.h:
7064 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7065 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7066 Maybe there is a similar problem with BORLANDC? It should be checked!
7068 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7069 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7070 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7071 was not executed, and the compiler (cl) launched a warning:
7072 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7074 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7075 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7077 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7078 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7080 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7081 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7082 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7083 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7084 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7085 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7086 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7087 - added Release configuration in VS projects
7088 - review of compiler an linker options
7089 - VC .exe files are generated in bin_vc directory, not to interfere
7090 with binaries generated from other projects (cygwin, mingw, bcc ...)
7092 * sdcc/src/yacc.dsp: added
7094 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7095 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7096 and insert the version number definitions from .version
7098 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7100 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7101 added - genarate auto-host.h using auto-host_vc_in.h as template
7104 removed from CVS, generated automatically
7106 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7107 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7109 2002-08-11 Borut Razem <borut.razem AT siol.net>
7110 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7112 2002-08-10 Borut Razem <borut.razem AT siol.net>
7113 * src/SDCCmain.c (main):
7114 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7115 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7116 The consequence was that some temporary files were not removed.
7119 unification of code in functions tempfilename() and tempfile():
7120 function tempnam() is defined in Visual Studio 6.0 and .NET
7122 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7124 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7125 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7126 - removed compiler command line option /WX: Treats all warnings as errors
7127 - update a list of source files, included into the project
7129 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7130 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7131 changed project type to Generic Project so that can be correcly converted to VS.NET project
7133 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7135 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7137 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7139 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7140 added return 0 statements after assert() to make compiler happy
7142 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7143 added newline in the def file to keep MSC compiler satisfied
7145 * sdcc/src/z80/gen.c:
7146 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7147 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7148 - solved MSC error in function aopDump()
7150 * sdcc_vc.h: define PREFIX as "\\sdcc"
7152 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7153 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7155 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7156 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7157 - Rewrote the register banking algorithm.
7158 - Added pCode live-range analysis to registers (for now, only non-used and
7159 singly-used registers optimized away)
7161 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

7192 2002-03-28 Johan Knol <johan AT balder>
7194 * src/SDCCval.c: fixed bug #532436
7196 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7198 Added "char *Processor" field to the port structure.
7201 Added -p option. Allows port dependent processor to be specified.
7204 Initialized the new field char *Processor field to NULL in all ports
7207 Compiler generated registers for interrupt context saving
7208 were not getting allocated.
7210 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7213 Fixed left shift. Will promote the left side of a left shift
7214 if a) left shifting more than size of operand or b) when assigned
7215 to something size > size of left side
7217 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7219 tons of changes. Register allocation has been
7220 rewritten. Added customization for the various PICs. Flow
7221 analysis is restructured. ...
7227 Added. device.c is a PIC port hack to accomodate variations
7230 2002-03-13 Michael Hope <michaelh AT vroom>
7232 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7325 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7327 * sdcc/src/SDCCloop.c:
7328 Previous fix was not good. basic blocks that have "break" or "return" are
7329 not really partof a loop , but live ranges used in these blocks should
7330 be live thru the entire loop, so set partOfLoop but don't add them to
7333 2002-02-21 <johan AT FRIJA>
7335 * src/SDCCcse.c: fixed bug #514308
7337 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7341 statement inside a loop, it was not being considered part of the loop.
7343 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7345 2002-02-10 Karl Bongers <karl AT turbobit.com>
7348 Fixed up SDCDB debugger somewhat. Updated debugger/README
7349 with lots of comments and notes.
7351 * device/examples/test2.c:
7352 Fix bug, "red" variable not being initialized(compiler complained).

7403 set preprocessor defines (depending on options)
7405 * src/SDCCicode.c, src/SDCCicode.h:
7406 changes made to handle multiple sends & receives
7409 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
