2761 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
2763 * src/SDCCast.c: added an additional type flow in decorateType() of
2764 opposite direction, see feature request #860006; it's enabled at runtime
2765 by setting the environment variable SDCC_NEWTYPEFLOW
2766 * src/SDCCast.h: changed prototype of decorateType()
2767 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2768 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2769 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2770 see feature request #877103

2799 * src/pic/ralloc.h: applied patch from Slade Rich;
2800 added support for multiple code pages and multiple RAM banks on the
2801 PIC 14 port. The ASM files now no longer simply assume all the
2802 code / RAM are in the same page / bank. This means the linker can
2803 safely allocate code/RAM of separate ASM files to different pages/banks.
2804 * doc/sdccman.lyx: added Slade's tips
2805 * src/mcs51/peeph.def: fixed bug #880768

2847 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2849 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2850 loaded with the linker search paths (-L arguments) and the libraries
2851 to be linked with the current source (-l arguments). Changes
2852 currently will affect only the pic16 port.
2853 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2854 include path the port specific paths and port specific libraries,
2855 * gplink command now contains the $3 argument,
2856 * src/pic16/device.h,
2857 * src/pic16/device.c,: structure PIC_device is made public and
2858 renamed to PIC16_device, the same for variable Pics which is renamed

2873 Documenting changes from previous commits.
2874 * configure.in (version 1.56),
2875 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2876 when generating output files to configure the pic16 library,
2877 but now I've commented it out, since gputils aren't installed in the
2878 SF compile farm, so library won't compile
2880 * device/lib/Makefile.in (version 1.56): initially I've added in
2881 target 'all' the prerequestive 'model-pic16' so it compiled the
2882 pic16 library, but now I've commented it out for the same reasons
2884 * added targets 'model-pic16' and 'objects-pic16' to compile the
2886 * added target 'port-specific-objects-pic16' to handle the
2887 generated libraries and copy them into the build/ directory
2888 * added target 'clean-intermediate-pic16' to clean intermediate
2889 files into pic16 directory
2890 * in target 'installdirs' added line to create directory pic16 in
2891 the installation path

2894 added lines to copy all header files to installation path,
2895 * in target 'installdirs' added line create directory for pic16
2896 headers in the installation path

2944 data are now emitted in sorted order to reduce section naming,
2945 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2946 weren't marked as being in the access bank,
2948 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2950 Added portion of GNU PIC Library under the directory
2951 device/include/pic16 and device/lib/pic16. These files
2952 contain the declarations of SFRs for the PIC18Fxx2 devices.
2953 The directory is initialized via configure from toplevel.

3181 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3183 PIC16 port related changes:
3184 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3185 added variable stackPos,
3187 * gen.c: genCall, assignResultValue: added support for
3188 pushing/retrieving function parameters to/from stack,
3189 genFunction,genEndFunction: setup stack frame for the
3191 genAddrOf: will be changed according to bug 863624
3193 * added files genutils.c and genutils.h which contain gen*
3194 debugged and optimised functions extracted from gen.c
3196 * glue.c: added variable 'externs' which holds extern symbols,
3197 pic16emitRegularMap: is modified to properly handle relocatable
3198 symbols under the new scheme,
3199 pic16createInterruptVect: is modified
3200 pic16printPublics: is modified to emit 'global' assembler directives,
3201 added pic16_printExterns to print extern symbols,
3202 pic16glue: initializes stack/frame pointer in the beginning of
3203 the assembly output. Temporary hack, will be corrected later,
3204 because gplink yet does not support stack and SDCC does not
3205 yet support a type of crt0.o object to create the final binary.
3207 * Removed many lines that contain 8051 legacy code.
3208 * The code is finally placed under a 'code' directive.
3209 * Added port specific options.
3211 * _process_pragma: simplified since now we do not need *special*
3212 include file to define SFR registers. But a separate header
3213 will be needed. This will be developed later.
3214 * _pic16_parseOptions: added, parses port specific options:
3215 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3216 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3217 --preplace-udata-with=
3219 * _pic16_setDefaultOptions: modified to initialize section names,
3220 but hack is temporarly out of order since it needs improvement.
3221 * _pic16_genAssemblerPreamble: configuration words are emitted by
3222 their address instead of their name. This part is incomplete and
3223 supports only the 18Fxx2 devices. Other devices will emit an error
3224 during assembly since they do not contain the same set of config
3226 * _pic16_genIVT: is modified,
3228 * pcode.c: added definitions for some hardware registers that are needed
3230 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3231 All PCI entries are updated. Now LFSR is supported.
3232 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3233 * added pic16_newpCodeOpLit2 to support instructions with
3234 two literal arguments
3235 * pic16_pCode2str: corrected code that emits assembler instructions
3236 with two literal operands and those that have an access bit modifier
3237 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3238 this fixes a bug which caused some labels to be lost, when an
3239 assembler directive was added, i.e. banksel,
3240 * pic16_FixRegisterBanking: improved logic that causes the insertion
3242 * InlineFunction: functions that are called once, are not any more
3243 inlined. This can be a port option in the future,
3245 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3247 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3248 hold the corresponding uninitialized symbols,
3249 * pic16_allocProcessorRegister: registers have explicit marked the
3251 * pic16_allocInternalRegister: registers are explicit marked as
3253 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3254 processing list, so bit registers were lost,
3257 * ralloc.h: added field 'accessBank' and original symbol operand
3258 in register definition,
3259 * removed the field isMapped from register definition,
3261 ** Several functions have been removed from various sources:
3262 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3263 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3264 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3265 pic16_assignRelocatableRegisters
3267 ** others have been introduced:
3268 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3269 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3271 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3273 * support/scripts/inc2h.pl: changed definition of BIT_AT
3274 to emit 'sbit at' instead of 'bit at'. This was a request.
3276 PIC16 port related preliminary changes:
3277 * gen.c: prefixed function popRegFromString with
3278 pic16_ and all references to it corrected
3279 * pcode.c: all pic16_pc_* hardware registers prefixed
3280 with underscore (_),
3281 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3282 * ralloc.c: newReg(): when register is REG_SFR then
3283 set address to rIdx,
3284 pic16_allocProcessorRegister(): marks register wasUsed=0
3285 pic16_writeUsedRegs(): added a call to assign processor
3286 registers via pic16_assignFixedRegisters
3288 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3290 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3291 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3292 variables in unused register banks. Also the SSEG is placed
3293 wherever there is enough space for it, and IDATA can be anywhere
3294 in internal RAM. For now compile using -Wl-Y[stack_size].
3295 The mem file is different for this option as well, since it
3296 makes no sense of talking about DSEG lenght.
3298 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3300 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3301 in certain cases, e.g. when ROM assignment, patch provided
3302 from Albert den Haan.

3543 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3545 * src/SDCCast.c (decorateType): disabled a transformation I added in
3546 revision 1.188 (access to fields of a structure at an absolute address);
3547 it breaks with bitfields, extern declarations, and gcse analysis.
3548 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3549 could be assigned through a pointer, so don't complain.
3550 * src/SDCCast.c (astErrors),

3654 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
3655 uninitialized variables) for the mcs51. Set environment variable

3657 xdata initialization slightly shorter
3659 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4306 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4307 fetching of the pointer
4308 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4309 copied from genNearPointerSet()
4310 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4311 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4327 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4328 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4329 type for bits was changed. It resulted in bit variables becoming
4330 global, which is not permitted in PIC 14 assembly output.
4332 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4334 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4347 A few small changes that speed up the peephole optimizer.
4351 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4353 Try to make the peephole optimizer smarter by maintaining
4354 an association between the assembly source code and the
4355 iCodes that originated them. Put this information to use
4356 with a new peephole rule condition "notVolatile" so that
4357 the rules can be aggressive yet still safe.
4362 * src/mcs51/peeph.def
4364 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4368 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4369 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4370 if the left or right operand symbols have the accuse flag set.
4372 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4374 Changed the type of the result of the ! (NOT) operator to char;
4375 previously it returned the same type as the source. This allows
4376 us to eliminate all the genFloatNot functions (all of its target
4377 implementations were very buggy) since !float can use the same
4380 * src/SDCCicode.c (ast2iCode): ! returns char

4389 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4390 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4391 during interrupts. Ensure WSAVE is located at a shared bank address.
4392 2. Fixed page selection in some places
4393 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4394 the registers name strings.
4395 4. Fixed "signed / unsigned compare" compiler warnings.
4396 5. The PIC port manages its own allocation of the general purpose
4397 registers, but makes no attempt to reuse them. As a result when
4398 compiling it soon runs out of general purpose registers. Some
4399 additional code was added to the files pcode.c and device.c to walk
4400 through the function call tree and rename the registers so that they
4410 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4411 genPlus() & genMinus() when the result is the same as left or right

4417 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4419 Made bitfield a distinct type from bit so that bitfields
4420 convert as per ANSI C and bits retain their traditional
4421 boolean style behaviour. Implemented bitfield support in
4429 * src/ds390/gen.c: bit v bitfield split
4430 * src/z80/gen.c: New support for bitfields
4431 * support/regression/tests/bitfields.c: reenabled z80,
4434 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4436 Rules 246.x, 247.x relate to bitfields, the others speed up
4437 access to xdata mapped I/O devices.
4439 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4441 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4443 Cleaned up genPackBits and genUnpackBits and added two helper
4444 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4445 for literal assignments in genPackBits (thanks to Frieder for
4451 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4453 Fixed bug #748310 (pointer to function type mishandled when the
4454 function name is omitted). Also fixed a SIGSEGV when a function
4455 attribute (reentrant, etc) is used on a non-function or on a
4456 function but misplaced before the parameter list.
4458 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4460 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4461 * support/Util/SDCCerr.h,

4483 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4485 Made the constant following the "interrupt" keyword optional. If
4486 omitted, the function will not automatically be given an entry
4487 in the interrupt vector table (similar to #pragma NOIV, but
4488 less syntacticly kludgy). The interrupt number is also now
4489 range checked. Also fixed a bug in the high order bit example

4503 * src/SDCCicode.c (operandOperation): rewritten some ops
4504 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4505 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4507 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4508 be re-activated by defining REDUCE_LITERALS)
4509 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4510 unsigned, but are signed by default
4511 * src/SDCCval.c (constVal): rearranged
4512 * src/SDCCval.c (valMod): preliminary fix
4513 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5018 * src/SDCCmain.c: linkOptions is changed to set *,
5019 added if/endif conditional macros to remove options help
5020 messages from optionsTable when a port is not configured, added
5021 support for the PIc16 port in the ports table, when executing
5022 the compiler with no port specified on command line, a default
5023 port is selected with the new macro DEFAULT_PORT which is
5024 defined in port.h, in setDefaultOptions() linkOptions is removed
5025 from initialization assignment, since now it is a set,
5026 parseCmdLine uses setParseWithComma for linkOptions, in
5027 linkEdit() linkOptions are accessed with new function indexSet()
5028 which returns the i'th item of a set variable. See SDCCset.c, in
5029 linkEdit() when calling buildCmdLine(), added linkOptions as
5030 last argument. Now users can pass arguments to gplink via the
5031 -Wl option, main() uses pic16glue() to glue up pic16 programs

5044 * src/pic16/main.c: __config directives are commented out to stop
5045 gpasm complaining and test the linkage with gplink, _linkCmd and
5046 _asmCmd changed to be more gplink and gpasm friendly
5047 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5048 produced an error when parsed, peep rule 12 is added to utilize
5049 movff, but it is commented out since the pCode does not support
5050 yet a command with 2 address arguments
5052 2003-05-18 <johan AT balder>
5054 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5081 2003-05-11 Borut Razem <borut.razem AT siol.net>
5083 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5084 the path of bin directory, so that PATH is the only env. variable, which has to be set
5085 in case of standard installation.

6138 * SDCClrange.h: exposed setFromRange() and setToRange()
6139 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6140 packRegsForAccUse() (bug 542397)
6141 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6142 multiple times and emitting the fetch operations more than once
6143 added aopGetUsesAcc() function to allow binary operators to
6144 fetch their operands in the correct order; made genMinus() emit
6145 compact code for X = LITERAL - Y
6147 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6148 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6149 sprintf() in line 1267.
6151 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6152 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6155 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6156 Changes to aslink (All the changes are marked with 'JCF'):
6158 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6161 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6162 area BSEG. Also moves, if possible, the DATA area down into the internal
6163 ram so more space is available.
6165 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6168 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6169 not bytes. Function summary() which creates a memory usage summary
6170 file with extension .mem. Reports of overlaping stack and small stack
6171 size. If the space for the stack is less than 16 bytes aslink trows a
6174 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6175 the 8051. Option 'y' for memory summary output file.
6177 Changes to sdcc (All the changes are marked with 'JCF'):
6179 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6181 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6182 overlaying area for it (uses RegBankUsed[4]).
6184 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6185 bank zero as used by default. By default aslink locates the stack
6186 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6187 the creation of the .mem file. Delegates the allocation of data area
6188 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6189 the begining of the stack area to aslink.
6191 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6192 glue() in SDCCglue.c creates an area for it.
6194 2002-09-03 Borut Razem <borut.razem AT siol.net>
6195 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6196 sdcc/src/pic/glue.c:
6197 introduced atexit() handler for teporay files removal in case of
6198 errors, assertions, ...
6200 2002-08-29 Borut Razem <borut.razem AT siol.net>
6201 * sdcc/support/cpp2/auto-host_vc_in.h:
6202 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6203 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6204 Maybe there is a similar problem with BORLANDC? It should be checked!
6206 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6207 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6208 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6209 was not executed, and the compiler (cl) launched a warning:
6210 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6212 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6213 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6215 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6216 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6218 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6219 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6220 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6221 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6222 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6223 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6224 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6225 - added Release configuration in VS projects
6226 - review of compiler an linker options
6227 - VC .exe files are generated in bin_vc directory, not to interfere
6228 with binaries generated from other projects (cygwin, mingw, bcc ...)
6230 * sdcc/src/yacc.dsp: added
6232 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6233 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6234 and insert the version number definitions from .version
6236 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6238 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6239 added - genarate auto-host.h using auto-host_vc_in.h as template
6242 removed from CVS, generated automatically
6244 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6245 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6247 2002-08-11 Borut Razem <borut.razem AT siol.net>
6248 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6250 2002-08-10 Borut Razem <borut.razem AT siol.net>
6251 * src/SDCCmain.c (main):
6252 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6253 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6254 The consequence was that some temporary files were not removed.
6257 unification of code in functions tempfilename() and tempfile():
6258 function tempnam() is defined in Visual Studio 6.0 and .NET
6260 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6262 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6263 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6264 - removed compiler command line option /WX: Treats all warnings as errors
6265 - update a list of source files, included into the project
6267 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6268 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6269 changed project type to Generic Project so that can be correcly converted to VS.NET project
6271 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6273 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6275 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6277 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6278 added return 0 statements after assert() to make compiler happy
6280 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6281 added newline in the def file to keep MSC compiler satisfied
6283 * sdcc/src/z80/gen.c:
6284 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6285 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6286 - solved MSC error in function aopDump()
6288 * sdcc_vc.h: define PREFIX as "\\sdcc"
6290 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6291 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6294 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6295 - Rewrote the register banking algorithm.
6296 - Added pCode live-range analysis to registers (for now, only non-used and
6297 singly-used registers optimized away)
6299 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

6330 2002-03-28 Johan Knol <johan AT balder>
6332 * src/SDCCval.c: fixed bug #532436
6334 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6336 Added "char *Processor" field to the port structure.
6339 Added -p option. Allows port dependent processor to be specified.
6342 Initialized the new field char *Processor field to NULL in all ports
6345 Compiler generated registers for interrupt context saving
6346 were not getting allocated.
6348 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6351 Fixed left shift. Will promote the left side of a left shift
6352 if a) left shifting more than size of operand or b) when assigned
6353 to something size > size of left side
6355 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6357 tons of changes. Register allocation has been
6358 rewritten. Added customization for the various PICs. Flow

6463 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6465 * sdcc/src/SDCCloop.c:
6466 Previous fix was not good. basic blocks that have "break" or "return" are
6467 not really partof a loop , but live ranges used in these blocks should
6468 be live thru the entire loop, so set partOfLoop but don't add them to
6471 2002-02-21 <johan AT FRIJA>
6473 * src/SDCCcse.c: fixed bug #514308
6475 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6478 Fixed BUG #519583. If a conditional block ended in a return/break
6479 statement inside a loop, it was not being considered part of the loop.
6481 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6483 2002-02-10 Karl Bongers <karl AT turbobit.com>
6486 Fixed up SDCDB debugger somewhat. Updated debugger/README
6487 with lots of comments and notes.
6489 * device/examples/test2.c:
6490 Fix bug, "red" variable not being initialized(compiler complained).

6494 for use as a multiple module SDCDB test case.
6496 * sim/ucsim/cmd.src/cmdset.cc:
6497 Took out debug printfs in ucsim "next" command.
6500 Karl and Johan start ucsim XA support. Most dissassembly working,

6541 set preprocessor defines (depending on options)
6543 * src/SDCCicode.c, src/SDCCicode.h:
6544 changes made to handle multiple sends & receives
6547 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
