2533 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2535 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2536 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2538 One basic decision: e.g. src/clean.mk includes further files. In order
2539 to make this work there are two solutions:
2540 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2541 run configure on them. This way they can use
2542 'include $(srcdir)/port-clean.mk'
2543 - always include clean.mk by the Makefile at the same level. To avoid
2544 that `make clean` tries to include and build Makefile.dep the
2545 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2546 implemented, because now even `make uninstall` doesn't create
2547 Makefile.in. clean.mk could be eliminated by pasting it in
2550 * debugger/mcs51/Makefile.in: build own objects from library sources
2551 (SLIB, SDCC) in current directory
2553 * configure, configure.in: renamed --disable-device-lib-build in
2554 --disable-device-lib; added --enable-doc, the required tools are
2555 searched by configure; added result message; the toolchain for the
2556 belonging ports are now only built, if the port is enabled.
2558 * support/regression/*: all output is written in directory gen, because
2559 the fwk and ports directories don't livet in the build tree using vpath
2561 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2562 --disable-device-lib, added --enable-doc, added section VPATH
2564 * sim/ucsim/configure.in,
2565 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2566 z80 are enabled by default
2568 2006-04-24 Raphael Neider <rneider AT web.de>
2570 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2571 to config word, "pic14_"-prefixed some extern functions
2572 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2573 config word has been found
2574 * src/pic/device.h: added prototypes
2575 * src/pic/pcode.c: added "pic14_"-prefix where needed
2576 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2578 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2580 (pic14emitRegularMap): ignore config words,
2581 (pic14createInterruptVect): moved generating __config directives away
2582 (picglue): have __config directives emitted
2584 2006-04-24 Borut Razem <borut.razem AT siol.net>
2586 * doc/Makefile: sync with nightly build makefile
2588 2006-04-24 Raphael Neider <rneider AT web.de>
2590 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2591 registers that have not been assigned proper liveranges,
2592 fixes #1469504 and #1474602,
2593 (pCodeRegOptimizeRegUsage): fixed typo in comment
2595 2006-04-24 Borut Razem <borut.razem AT siol.net>
2597 * device/examples/main8051.c: deleted - it was removed from CVS
2598 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2599 after the transition to Subversion
2600 * src/SDCCalloc.h: deleted - it was removed from CVS
2601 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2841 and enabled nesting of critical functions though not for gbz80
2842 (genCritical, genEndCritical): added functions
2843 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2844 * src/z80/mappings.i: added "ei" to all mappings

2856 the left operand is shorter than the result (c* = lit-c* + int),
2858 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2861 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2863 * src/.version: increased version number to 2.5.5
2864 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2865 linking is done manually in pic16 port's _linkEdit,
2866 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2867 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2868 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2869 allocate asmop as AOP_ACC,
2870 (aopForRemat): added parameter 'bool result' in function declaration,
2871 (pic16_aopGet): return AOP_ACC when accessing WREG,
2872 (pic16_popGetTempReg): minor modification,

2883 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2884 call to allocReg, not by manually allocating a new one,
2885 (pic16_assignRegisters): now before going through the register
2886 allocating functions mark all registers as free. This eliminates some
2887 side effects resulting from peephole parser done earlier in the backbone
2889 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2947 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2948 which dumps before the function entry point a data byte which represents
2949 the number of the local variables used by the specified function, added
2950 'xinst' for initial support for Extended Instruction Support,
2951 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2952 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2953 port->fun_prefix anymore (may change later),
2954 (genFunction, genEndFunction): do not store/restore local registers for
2955 _main (this should take care the --main-return command line option in
2957 (genOr): removed some legacy pic-port instructions,
2958 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2959 performing operations with SFR's causes data to be written more than
2960 once to each SFR. Perhaps SFRs should be handled in special cases...
2961 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2963 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2964 into account for stack starting position,

2968 (deassignLRs): *** perhaps the most important change, old 'for' code
2969 (commented out for reference), didn't account for some registers which
2970 were left marked 'not free' after a pointer operation. The change
2971 reduces register usage a lot in some cases
2973 2006-03-04 Borut Razem <borut.razem AT siol.net>

5246 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5247 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5248 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5249 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5250 always available in leading double underscore form. The C99 support is
5251 mostly missing, but it's a start.
5252 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5253 reserved identifier "__data".
5255 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5331 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5333 * device/lib/printf_large.c: removed inline assembly for portability and
5334 readability. Use printf_fast if speed or size are more important.
5335 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5336 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5338 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5340 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5341 prevent compiler warning
5343 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5345 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5346 moved to level 0 and declared as static. Also they are explicit
5347 placed in access bank. This was necessery because some times they
5348 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5349 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5350 optimizations. Currently only compare to unsigned char is implemented,
5351 * src/pic16/gen.c: added fReturnIdx array,
5352 * (struct resolvedIfx) is moved to gen.h and made public,
5353 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5354 * (aopForSym): added an optimization to directly store in stack of
5355 the operand of a SEND iCode,
5356 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5357 but as registers instead (AOP_REG) using the fReturnIdx array,
5358 * (pic16_freeAsmop): remove the freed register from the
5359 _G.sregsAlloc field,
5360 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5361 a compare of 'WREG',
5362 * (pic16_popGetTempRegCond): changed function prototype, now
5363 function takes also a bitVector argument v which holds the current
5364 set of registers that are allocated for stack access by aopForSym,
5365 registers allocated in aopForSym for accessing stack symbols are not
5366 any more part of the functions usedRegs field,
5367 * (genCall): some times aopOp is called for a stack variable to be
5368 send, aopForSym might perform the push, if this is true make sure
5369 that genCall doesn't push the variable twice by testing _G.resDirect,
5370 * (genFunction): changed testing for unspecified interrupt number
5371 from 256 to INTNO_UNSPEC,
5372 * modified selection scheme of frame pointer generation. Previously
5373 if function did use local registers a frame pointer was generated,
5374 now a frame pointer is generated only if function has arguments
5375 (that need PLUSW2 register access), or has stack arguments, or the
5376 compiler is not instructed to omit the frame pointer,
5377 * (genEndFunction): before restoring local registers that were saved
5378 in the function preamble, also restore the registers that *might*
5379 have been allocated for stack access,
5380 * (genRet): removed some old comments,
5381 * (genCmp, the active (RN's) version): added a call to the
5382 pic16_genCmp_special function to perform the compare with a more
5383 robust and optimized way,
5384 * (genInline): a feature has been added in inline code generation,
5385 which allows a wildcard variable substitution when writing inline
5386 assembly. Code is incomplete and experimental therefore undocumented,
5387 * (genCast): changed order of aopOp for result and right to allow
5388 aopForSym to directly load the result if possible,
5389 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5390 perform an optimized compare on some selected special occasions,
5391 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5392 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5393 generate an IVT any more,
5394 * src/pic16/main.c (pic16_optionsTable): added command line option
5396 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5397 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5399 * src/pic16/NOTES: Raphael Neider added in list of active developers
5400 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5401 jumptable_end to prevent bug #,
5402 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5403 inCond and outCond fields,
5404 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5405 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5406 turn off register spilling,
5407 * (packRegsForOneUse): synced with other ports' versions although it
5408 is not used currently,
5409 * (pic16_packRegisters): added an optimization while reading
5410 structure bitfields, some registers may be saved (malloc code is
5411 decreased by 80 bytes)
5413 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5415 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5416 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5417 this can be optimized more?
5419 2005-03-10 Raphael Neider <rneider AT web.de>
5421 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5422 genNearPointerGet): (hopefully) fixed access to bitfields via
5423 pointers (p->bitN = x; and x = p->bitN; failed)

6057 Adding support for replacing ljmps with sjmps in jumptables
6058 generated for switch statements. For now you need to set the
6059 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6060 Now 4 algorithms for mcs51 jumptable generation are used:
6061 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6062 addresses loaded pc-relative for up to 112 cases and stack-pushing
6063 target addresses loaded with offset from dptr for up to 256 cases.

6090 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6091 to call when a stack overflow occurs,
6092 * (malloc.h): added CVS Id tag,
6093 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6095 * added libc directory. The current version of LibC contains string
6096 functions, ctype functions and macros and some functions of the
6097 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6098 be extensively tested in the future. Standard disclaimer here.
6099 Library is not automatically build yet. But one can build it by
6100 invoking 'make' inside the libc directory.
6101 * added ADC library under libio. Preliminary version yet.

6110 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6111 * (pic16_storeForReturn): optimized return of 0,
6112 * (genCmp): experimental code for new genCmp which uses PIC18's
6113 special compare&skip instructions. Initial tests fail some times
6114 with variables grater than 1 byte in size, so new code is disabled,
6115 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6117 * (genCast): began a fix to optimize the casting of a bit to another
6118 bit, now assigning a bitfield to another bitfield will fail, sorry,
6119 * src/pic16/main.c: disabled the use of lr-support feature,
6120 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6123 bits with offset (case PO_GPR_BIT),
6124 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6126 * (isBankInstruction): modified to return 0 for no banking instruction,
6127 and 1 for banking instruction,
6128 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6129 caused stop processing pCodes after a inline assembly block,
6130 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6131 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6132 registers when it shouldn't,
6133 * src/pic16/ralloc.c (allocReg): add preliminary support for
6134 supporting a limited set of temporary registers,
6136 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6138 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6139 genDataPointerSet): ensure assignments always copy in MSB to LSB
6141 (loadRegFromAop): recognize CLRH optimization,
6142 (genFunction): optimize RECEIVE iCodes in reentrant functions
6144 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6146 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9093 * src/pic/ralloc.h: applied patch from Slade Rich;
9094 added support for multiple code pages and multiple RAM banks on the
9095 PIC 14 port. The ASM files now no longer simply assume all the
9096 code / RAM are in the same page / bank. This means the linker can
9097 safely allocate code/RAM of separate ASM files to different pages/banks.
9098 * doc/sdccman.lyx: added Slade's tips
9099 * src/mcs51/peeph.def: fixed bug #880768

9108 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
9111 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9112 strtof is not part of C89 and isn't included with Mac OS X.
9114 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9116 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
9117 shiftL2Left2Result): fixed bug #879326
9118 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

9141 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9143 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9144 loaded with the linker search paths (-L arguments) and the libraries
9145 to be linked with the current source (-l arguments). Changes
9146 currently will affect only the pic16 port.
9147 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9148 include path the port specific paths and port specific libraries,
9149 * gplink command now contains the $3 argument,
9150 * src/pic16/device.h,
9151 * src/pic16/device.c,: structure PIC_device is made public and
9152 renamed to PIC16_device, the same for variable Pics which is renamed
9153 to Pics16. Updated all references to them.
9154 * src/pic16/glue.c (pic16glue): corrected bug with code
9155 initialization which bypassed the variable initializations block.
9157 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9158 COMPILE_FLAGS and added the --nostdinc option
9160 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9165 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9167 Documenting changes from previous commits.
9168 * configure.in (version 1.56),
9169 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9170 when generating output files to configure the pic16 library,
9171 but now I've commented it out, since gputils aren't installed in the
9172 SF compile farm, so library won't compile
9174 * device/lib/Makefile.in (version 1.56): initially I've added in
9175 target 'all' the prerequestive 'model-pic16' so it compiled the
9176 pic16 library, but now I've commented it out for the same reasons
9178 * added targets 'model-pic16' and 'objects-pic16' to compile the
9180 * added target 'port-specific-objects-pic16' to handle the
9181 generated libraries and copy them into the build/ directory
9182 * added target 'clean-intermediate-pic16' to clean intermediate
9183 files into pic16 directory
9184 * in target 'installdirs' added line to create directory pic16 in
9185 the installation path
9187 * device/include/Makefile.in (version 1.11): in target 'install'
9188 added lines to copy all header files to installation path,
9189 * in target 'installdirs' added line create directory for pic16
9190 headers in the installation path

9205 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9206 option so that it actually works. Made it specific to the z80, since
9207 the gbz80 doesn't have these kinds of I/O ports.
9209 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9211 * device/include/z180.h,

9224 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9226 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9227 changed interrupt vector table generation to only emit declared vectors.

9233 Mainly changes to support compilation of the device libraries
9234 * src/pic16/device.c: stack is allocated via symbol and not
9235 via literal number. The symbol is placed in the corresponding
9236 position of the data ram
9237 * (pic16_dump_section): relocatable and absolute uninitialized
9238 data are now emitted in sorted order to reduce section naming,
9239 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9240 weren't marked as being in the access bank,
9242 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9244 Added portion of GNU PIC Library under the directory
9245 device/include/pic16 and device/lib/pic16. These files
9246 contain the declarations of SFRs for the PIC18Fxx2 devices.
9247 The directory is initialized via configure from toplevel.
9249 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9251 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9252 the spilllocations to be compared correctly
9254 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

9263 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9265 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
9266 in simpler and even better code
9268 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
9270 * src/SDCCicode.c (operandOperation): fixed bug #874819

9276 * doc/sdccman.lyx: Moved and added some sections, small changes
9277 all over. Telling LaTeX to be less strict with word spacing
9278 to better keep the right margin. Changed some notes about
9279 maintainance of the ports in section 3.2.1 - is it OK like this?
9281 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9318 UPPER for immediate operands,
9319 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9321 * src/pic16/peeph.def: all peepholes with movff are commented out,
9322 because there is a problem in the pcode peep optimizer,
9323 * src/pic16/ralloc.c: the register allocator can now reuse local

9325 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9327 Added file src/pic16/NOTES with information about program writing on
9328 the current port version.

9381 needLinkerScript flag
9383 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9384 * src/pic/glue.c: added variable udata_section_name to
9385 override default uninitialized data segment definition for
9386 devices only with SHAREBANK memory (reported from Erik Epetrich)
9387 * (pic14emitOverlay): modified to emit a commented overlay segment
9388 directive when no overlay data exist
9389 * (picglue): modified to emit uninitialized data segment
9390 according to udata_section_name

9438 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9440 A python script to validate compiler diagnostic messages. It can be
9441 used to verify that sdcc complains about bad c source code and
9442 gives a good location of the error.
9443 * support/valdiag/Makefile,
9444 * support/valdiag/valdiag.py,
9445 * support/valdiag/tests/*
9447 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9462 Bug reported from Jesus Calvino-Fraga
9464 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9466 * sdcc.spec: updated
9467 * device/include/Makefile.in: don't install CVS directories

9475 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9477 PIC16 port related changes:
9478 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9479 added variable stackPos,
9481 * gen.c: genCall, assignResultValue: added support for
9482 pushing/retrieving function parameters to/from stack,
9483 genFunction,genEndFunction: setup stack frame for the
9485 genAddrOf: will be changed according to bug 863624
9487 * added files genutils.c and genutils.h which contain gen*
9488 debugged and optimised functions extracted from gen.c
9490 * glue.c: added variable 'externs' which holds extern symbols,
9491 pic16emitRegularMap: is modified to properly handle relocatable
9492 symbols under the new scheme,
9493 pic16createInterruptVect: is modified
9494 pic16printPublics: is modified to emit 'global' assembler directives,
9495 added pic16_printExterns to print extern symbols,
9496 pic16glue: initializes stack/frame pointer in the beginning of
9497 the assembly output. Temporary hack, will be corrected later,
9498 because gplink yet does not support stack and SDCC does not
9499 yet support a type of crt0.o object to create the final binary.
9501 * Removed many lines that contain 8051 legacy code.
9502 * The code is finally placed under a 'code' directive.
9503 * Added port specific options.
9505 * _process_pragma: simplified since now we do not need *special*
9506 include file to define SFR registers. But a separate header
9507 will be needed. This will be developed later.
9508 * _pic16_parseOptions: added, parses port specific options:
9509 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9510 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9511 --preplace-udata-with=
9513 * _pic16_setDefaultOptions: modified to initialize section names,
9514 but hack is temporarly out of order since it needs improvement.
9515 * _pic16_genAssemblerPreamble: configuration words are emitted by
9516 their address instead of their name. This part is incomplete and
9517 supports only the 18Fxx2 devices. Other devices will emit an error
9518 during assembly since they do not contain the same set of config
9520 * _pic16_genIVT: is modified,
9522 * pcode.c: added definitions for some hardware registers that are needed
9524 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9525 All PCI entries are updated. Now LFSR is supported.
9526 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9527 * added pic16_newpCodeOpLit2 to support instructions with
9528 two literal arguments
9529 * pic16_pCode2str: corrected code that emits assembler instructions
9530 with two literal operands and those that have an access bit modifier
9531 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9532 this fixes a bug which caused some labels to be lost, when an
9533 assembler directive was added, i.e. banksel,
9534 * pic16_FixRegisterBanking: improved logic that causes the insertion
9536 * InlineFunction: functions that are called once, are not any more
9537 inlined. This can be a port option in the future,
9539 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9541 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9542 hold the corresponding uninitialized symbols,
9543 * pic16_allocProcessorRegister: registers have explicit marked the
9545 * pic16_allocInternalRegister: registers are explicit marked as
9547 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9548 processing list, so bit registers were lost,
9551 * ralloc.h: added field 'accessBank' and original symbol operand
9552 in register definition,
9553 * removed the field isMapped from register definition,
9555 ** Several functions have been removed from various sources:
9556 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9557 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9558 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9559 pic16_assignRelocatableRegisters
9561 ** others have been introduced:
9562 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9563 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9565 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9567 * support/scripts/inc2h.pl: changed definition of BIT_AT
9568 to emit 'sbit at' instead of 'bit at'. This was a request.
9570 PIC16 port related preliminary changes:
9571 * gen.c: prefixed function popRegFromString with
9572 pic16_ and all references to it corrected
9573 * pcode.c: all pic16_pc_* hardware registers prefixed
9574 with underscore (_),
9575 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9576 * ralloc.c: newReg(): when register is REG_SFR then
9577 set address to rIdx,
9578 pic16_allocProcessorRegister(): marks register wasUsed=0
9579 pic16_writeUsedRegs(): added a call to assign processor
9580 registers via pic16_assignFixedRegisters
9582 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9584 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9585 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9586 variables in unused register banks. Also the SSEG is placed
9587 wherever there is enough space for it, and IDATA can be anywhere
9588 in internal RAM. For now compile using -Wl-Y[stack_size].
9589 The mem file is different for this option as well, since it
9590 makes no sense of talking about DSEG lenght.
9592 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9594 * src/SDCClrange.c: fixed bug 869095 that caused segfault

10578 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10580 * device/lib/_mullong.c: replaced int by short for gcc
10582 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10584 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10585 and JUMPTABLE iCodes properly now (worked by accident before)
10586 * src/mcs51/gen.c (leftRightUseAcc),
10587 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10588 iCode properly now. Use getSize instead of nRegs since a & b
10589 aren't part of the nRegs tally.
10591 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10593 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10603 copied from genNearPointerSet()
10604 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10605 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10606 If they pop r0/r1 they must be called in the opposite order than aopOp().
10607 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10608 (resp. --stack-auto), prepared for --xstack
10610 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10612 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10614 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10619 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10621 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10622 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10623 type for bits was changed. It resulted in bit variables becoming
10624 global, which is not permitted in PIC 14 assembly output.
10626 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10628 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10630 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10632 Z80 and MCS51 linkers complaint if a public symbol is defined
10633 in more than one library module:

10639 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10641 A few small changes that speed up the peephole optimizer.
10645 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10647 Try to make the peephole optimizer smarter by maintaining
10648 an association between the assembly source code and the
10649 iCodes that originated them. Put this information to use
10650 with a new peephole rule condition "notVolatile" so that
10651 the rules can be aggressive yet still safe.
10656 * src/mcs51/peeph.def
10658 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10662 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10663 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10664 if the left or right operand symbols have the accuse flag set.
10666 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10668 Changed the type of the result of the ! (NOT) operator to char;
10669 previously it returned the same type as the source. This allows
10670 us to eliminate all the genFloatNot functions (all of its target
10671 implementations were very buggy) since !float can use the same
10674 * src/SDCCicode.c (ast2iCode): ! returns char
10675 * src/mcs51/gen.c (genNot, genNotFloat),
10676 * src/ds390/gen.c (genNot, genNotFloat),
10677 * src/z80/gen.c (genNot, genNotFloat),
10678 * src/pic/gen.c (genNot, genNotFloat),
10679 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10683 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10684 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10685 during interrupts. Ensure WSAVE is located at a shared bank address.
10686 2. Fixed page selection in some places
10687 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10688 the registers name strings.
10689 4. Fixed "signed / unsigned compare" compiler warnings.
10690 5. The PIC port manages its own allocation of the general purpose
10691 registers, but makes no attempt to reuse them. As a result when
10692 compiling it soon runs out of general purpose registers. Some
10693 additional code was added to the files pcode.c and device.c to walk
10694 through the function call tree and rename the registers so that they
10704 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10705 genPlus() & genMinus() when the result is the same as left or right
10707 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10711 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10713 Made bitfield a distinct type from bit so that bitfields
10714 convert as per ANSI C and bits retain their traditional
10715 boolean style behaviour. Implemented bitfield support in
10723 * src/ds390/gen.c: bit v bitfield split
10724 * src/z80/gen.c: New support for bitfields
10725 * support/regression/tests/bitfields.c: reenabled z80,
10728 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10730 Rules 246.x, 247.x relate to bitfields, the others speed up
10731 access to xdata mapped I/O devices.
10733 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10735 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10737 Cleaned up genPackBits and genUnpackBits and added two helper
10738 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10739 for literal assignments in genPackBits (thanks to Frieder for
10745 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10747 Fixed bug #748310 (pointer to function type mishandled when the
10748 function name is omitted). Also fixed a SIGSEGV when a function
10749 attribute (reentrant, etc) is used on a non-function or on a
10750 function but misplaced before the parameter list.
10752 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10754 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10755 * support/Util/SDCCerr.h,
10756 * support/Util/SDCCerr.c: Added func attr misuse error msg
10758 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10760 Fixed bug #787649 by anonymous
10761 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10762 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10764 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10777 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10779 Made the constant following the "interrupt" keyword optional. If
10780 omitted, the function will not automatically be given an entry
10781 in the interrupt vector table (similar to #pragma NOIV, but
10782 less syntacticly kludgy). The interrupt number is also now
10783 range checked. Also fixed a bug in the high order bit example

10799 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10801 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10802 be re-activated by defining REDUCE_LITERALS)
10803 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10804 unsigned, but are signed by default
10805 * src/SDCCval.c (constVal): rearranged
10806 * src/SDCCval.c (valMod): preliminary fix
10807 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10847 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10848 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10849 constants are unsigned; added recognition of "u" flag for unsigned
10850 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10851 * src/SDCCval.c (valDiv, valMod): fixed signdness
10852 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10853 signedness of modulo, left and right shift

11260 the regression tests I'm not brave enough to enable 245.b, 245.c
11261 * doc/sdccman.lyx: added latex preamble for hyperref package.
11262 Using pdflatex this will give you a hyperlinked pdf file with

11313 added if/endif conditional macros to remove options help
11314 messages from optionsTable when a port is not configured, added
11315 support for the PIc16 port in the ports table, when executing
11316 the compiler with no port specified on command line, a default
11317 port is selected with the new macro DEFAULT_PORT which is
11318 defined in port.h, in setDefaultOptions() linkOptions is removed
11319 from initialization assignment, since now it is a set,
11320 parseCmdLine uses setParseWithComma for linkOptions, in
11321 linkEdit() linkOptions are accessed with new function indexSet()
11322 which returns the i'th item of a set variable. See SDCCset.c, in
11323 linkEdit() when calling buildCmdLine(), added linkOptions as
11324 last argument. Now users can pass arguments to gplink via the
11325 -Wl option, main() uses pic16glue() to glue up pic16 programs

11337 * src/pic16/glue.c: commented out some error producing lines
11338 * src/pic16/main.c: __config directives are commented out to stop
11339 gpasm complaining and test the linkage with gplink, _linkCmd and
11340 _asmCmd changed to be more gplink and gpasm friendly
11341 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11342 produced an error when parsed, peep rule 12 is added to utilize
11343 movff, but it is commented out since the pCode does not support
11344 yet a command with 2 address arguments
11346 2003-05-18 <johan AT balder>
11348 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12383 * src/SDCCicode.c: fixed array add
12385 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12386 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12387 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12389 2003-01-04 <johan AT balder>
12391 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12393 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12394 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12396 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12397 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12398 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12400 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12401 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12403 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12404 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12406 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12407 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12409 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12411 * in /sdcc/as/mcs51/ changed these files in order to create an
12412 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12413 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12414 following files to include the previous two files: aslink.dsp,
12415 Makefile.aslink, Makefile.bcc, and Makefile.in.
12417 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12418 .adb instead of .cdb
12420 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12422 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12423 value from option --iram-size.
12425 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12427 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12430 2002-09-18 <wiml AT hhhh.org>
12432 * SDCClrange.h: exposed setFromRange() and setToRange()
12433 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12434 packRegsForAccUse() (bug 542397)
12435 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12436 multiple times and emitting the fetch operations more than once
12437 added aopGetUsesAcc() function to allow binary operators to
12438 fetch their operands in the correct order; made genMinus() emit
12439 compact code for X = LITERAL - Y
12441 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12442 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12443 sprintf() in line 1267.
12445 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12446 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12449 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12450 Changes to aslink (All the changes are marked with 'JCF'):
12452 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12455 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12456 area BSEG. Also moves, if possible, the DATA area down into the internal
12457 ram so more space is available.
12459 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12462 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12463 not bytes. Function summary() which creates a memory usage summary
12464 file with extension .mem. Reports of overlaping stack and small stack
12465 size. If the space for the stack is less than 16 bytes aslink trows a
12468 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12469 the 8051. Option 'y' for memory summary output file.
12471 Changes to sdcc (All the changes are marked with 'JCF'):
12473 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12475 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12476 overlaying area for it (uses RegBankUsed[4]).
12478 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12479 bank zero as used by default. By default aslink locates the stack
12480 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12481 the creation of the .mem file. Delegates the allocation of data area
12482 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12483 the begining of the stack area to aslink.
12485 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12486 glue() in SDCCglue.c creates an area for it.
12488 2002-09-03 Borut Razem <borut.razem AT siol.net>
12489 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12490 sdcc/src/pic/glue.c:
12491 introduced atexit() handler for teporay files removal in case of
12492 errors, assertions, ...
12494 2002-08-29 Borut Razem <borut.razem AT siol.net>
12495 * sdcc/support/cpp2/auto-host_vc_in.h:
12496 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12497 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12498 Maybe there is a similar problem with BORLANDC? It should be checked!
12500 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12501 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12502 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12503 was not executed, and the compiler (cl) launched a warning:
12504 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12506 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12507 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12509 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12510 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12512 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12513 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12514 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12515 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12516 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12517 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12518 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12519 - added Release configuration in VS projects
12520 - review of compiler an linker options
12521 - VC .exe files are generated in bin_vc directory, not to interfere
12522 with binaries generated from other projects (cygwin, mingw, bcc ...)
12524 * sdcc/src/yacc.dsp: added
12526 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12527 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12528 and insert the version number definitions from .version
12530 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12532 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12533 added - genarate auto-host.h using auto-host_vc_in.h as template
12536 removed from CVS, generated automatically
12538 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12539 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12541 2002-08-11 Borut Razem <borut.razem AT siol.net>
12542 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12544 2002-08-10 Borut Razem <borut.razem AT siol.net>
12545 * src/SDCCmain.c (main):
12546 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12547 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12548 The consequence was that some temporary files were not removed.
12551 unification of code in functions tempfilename() and tempfile():
12552 function tempnam() is defined in Visual Studio 6.0 and .NET
12554 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12556 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12557 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12558 - removed compiler command line option /WX: Treats all warnings as errors
12559 - update a list of source files, included into the project
12561 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12562 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12563 changed project type to Generic Project so that can be correcly converted to VS.NET project
12565 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12567 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12569 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12571 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12572 added return 0 statements after assert() to make compiler happy
12574 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12575 added newline in the def file to keep MSC compiler satisfied
12577 * sdcc/src/z80/gen.c:
12578 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12579 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12580 - solved MSC error in function aopDump()
12582 * sdcc_vc.h: define PREFIX as "\\sdcc"
12584 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12585 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12588 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12589 - Rewrote the register banking algorithm.
12590 - Added pCode live-range analysis to registers (for now, only non-used and
12591 singly-used registers optimized away)
12593 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12595 * 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.

12620 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12622 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12624 2002-03-28 Johan Knol <johan AT balder>
12626 * src/SDCCval.c: fixed bug #532436
12628 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12630 Added "char *Processor" field to the port structure.
12633 Added -p option. Allows port dependent processor to be specified.
12636 Initialized the new field char *Processor field to NULL in all ports
12639 Compiler generated registers for interrupt context saving
12640 were not getting allocated.
12642 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12645 Fixed left shift. Will promote the left side of a left shift
12646 if a) left shifting more than size of operand or b) when assigned
12647 to something size > size of left side
12649 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12651 tons of changes. Register allocation has been
12652 rewritten. Added customization for the various PICs. Flow
12653 analysis is restructured. ...
12655 * src/pic/device.h:
12658 * src/pic/device.c:
12659 Added. device.c is a PIC port hack to accomodate variations
12662 2002-03-13 Michael Hope <michaelh AT vroom>
12664 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12666 2002-03-04 johanknol <johanknol AT manik>
12668 * /src/SDCCval.c: fixed
12670 const unsigned char arr[][2] = { { 0, 1 } };

12757 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12759 * sdcc/src/SDCCloop.c:
12760 Previous fix was not good. basic blocks that have "break" or "return" are
12761 not really partof a loop , but live ranges used in these blocks should
12762 be live thru the entire loop, so set partOfLoop but don't add them to
12765 2002-02-21 <johan AT FRIJA>
12767 * src/SDCCcse.c: fixed bug #514308
12769 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12772 Fixed BUG #519583. If a conditional block ended in a return/break
12773 statement inside a loop, it was not being considered part of the loop.
12775 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12777 2002-02-10 Karl Bongers <karl AT turbobit.com>

12786 * device/examples/Makefile, examples/test3.c:
12787 Add Makefile in device/examples folder, compiles test3.c
12788 for use as a multiple module SDCDB test case.
12790 * sim/ucsim/cmd.src/cmdset.cc:
12791 Took out debug printfs in ucsim "next" command.
12793 * sim/ucsim/xa.src:
12794 Karl and Johan start ucsim XA support. Most dissassembly working,
12795 about 75% emulation done(plenty of work remaining).
12797 * sim/ucsim/z80.src:
12798 Add Z80 support to ucsim, add test-ucz80 regression test,
12799 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
12800 Notice z80 compiler fails on examples/test3.c/crc code.
12802 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

12816 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
12817 1) handle multiple send & receives from register bank1
12818 2) ralloc can now allocate DPTR1 to some liveRanges
12820 * src/SDCCsymt.c, src/SDCCsymt.h:
12821 changes to handle multiple sends & receives
12823 * src/SDCCptropt.h:
12824 added some pointer arithmetic optimization
12826 * src/SDCCptropt.c:

12828 called from anywhere (will get this working shortly)
12830 * src/SDCCopt.c: fixed for multiple sends & receives
12833 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
12834 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
12835 set preprocessor defines (depending on options)
12837 * src/SDCCicode.c, src/SDCCicode.h:
12838 changes made to handle multiple sends & receives
12841 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
