2355 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2357 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2358 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2360 One basic decision: e.g. src/clean.mk includes further files. In order
2361 to make this work there are two solutions:
2362 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2363 run configure on them. This way they can use
2364 'include $(srcdir)/port-clean.mk'
2365 - always include clean.mk by the Makefile at the same level. To avoid
2366 that `make clean` tries to include and build Makefile.dep the
2367 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2368 implemented, because now even `make uninstall` doesn't create
2369 Makefile.in. clean.mk could be eliminated by pasting it in
2372 * debugger/mcs51/Makefile.in: build own objects from library sources
2373 (SLIB, SDCC) in current directory
2375 * configure, configure.in: renamed --disable-device-lib-build in
2376 --disable-device-lib; added --enable-doc, the required tools are
2377 searched by configure; added result message; the toolchain for the
2378 belonging ports are now only built, if the port is enabled.
2380 * support/regression/*: all output is written in directory gen, because
2381 the fwk and ports directories don't livet in the build tree using vpath
2383 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2384 --disable-device-lib, added --enable-doc, added section VPATH
2386 * sim/ucsim/configure.in,
2387 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2388 z80 are enabled by default
2390 2006-04-24 Raphael Neider <rneider AT web.de>
2392 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2393 to config word, "pic14_"-prefixed some extern functions
2394 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2395 config word has been found
2396 * src/pic/device.h: added prototypes
2397 * src/pic/pcode.c: added "pic14_"-prefix where needed
2398 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2400 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2414 fixes #1469504 and #1474602,
2415 (pCodeRegOptimizeRegUsage): fixed typo in comment

2638 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2640 * src/mcs51/gen.c (genCall): fixed bug 1457608
2642 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2644 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

2647 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2649 * src/SDCCpeeph.c (operandsLiteral): new, added,

2660 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2661 implemented patch 1120823 Thanks to Willy De la Court (normal
2662 interrupts need an interrupt number now if they are made critical),
2663 and enabled nesting of critical functions though not for gbz80
2664 (genCritical, genEndCritical): added functions
2665 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2666 * src/z80/mappings.i: added "ei" to all mappings

2670 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2671 submitted by the Debian SDCC maintainer Aurelien Jarno:
2672 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2673 archive with gcc 4.1 on mips and wrote the patch"
2675 2006-03-16 Raphael Neider <rneider AT web.de>
2677 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2678 the left operand is shorter than the result (c* = lit-c* + int),
2680 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2683 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2685 * src/.version: increased version number to 2.5.5
2686 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2687 linking is done manually in pic16 port's _linkEdit,
2688 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2689 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2690 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2691 allocate asmop as AOP_ACC,
2692 (aopForRemat): added parameter 'bool result' in function declaration,
2693 (pic16_aopGet): return AOP_ACC when accessing WREG,
2694 (pic16_popGetTempReg): minor modification,
2695 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2696 'pic16_allocWithIdx',
2697 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2698 calling function in absolute addresses,
2699 (genAssign): take into account AOP_ACC asmop,
2700 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

2703 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2705 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2706 call to allocReg, not by manually allocating a new one,
2707 (pic16_assignRegisters): now before going through the register
2708 allocating functions mark all registers as free. This eliminates some
2709 side effects resulting from peephole parser done earlier in the backbone
2711 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2713 * src/SDCCicode.c (geniCodeLogic),

2732 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2733 (aopForSym, aopOp): increment asmop.allocated if reused,
2734 (freeAsmop): decrement asmop.allocated and check for zero instead of
2736 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2737 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2738 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2761 2006-03-06 Borut Razem <borut.razem AT siol.net>
2763 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2764 made the linker quiet
2766 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2768 * src/pic16/gen.c (genPcall): fixed bug #1443644
2769 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2770 which dumps before the function entry point a data byte which represents
2771 the number of the local variables used by the specified function, added
2772 'xinst' for initial support for Extended Instruction Support,
2773 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2774 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2775 port->fun_prefix anymore (may change later),
2776 (genFunction, genEndFunction): do not store/restore local registers for
2777 _main (this should take care the --main-return command line option in
2779 (genOr): removed some legacy pic-port instructions,
2780 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2781 performing operations with SFR's causes data to be written more than
2782 once to each SFR. Perhaps SFRs should be handled in special cases...
2783 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2785 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2786 into account for stack starting position,
2787 (struct OPTIONS pic16_optionsTable): added command line argument
2788 --extended or -y for Extended Instruction Support,
2789 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2790 (deassignLRs): *** perhaps the most important change, old 'for' code
2791 (commented out for reference), didn't account for some registers which
2792 were left marked 'not free' after a pointer operation. The change
2793 reduces register usage a lot in some cases
2795 2006-03-04 Borut Razem <borut.razem AT siol.net>
2797 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5118 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
5119 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5120 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5121 immedDom() returning wrong block; probably fixes bug #1160833)
5123 2005-03-20 Borut Razem <borut.razem AT siol.net>
5125 * support/scripts/inc2h.pl: WIN32 port
5127 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5129 * device/lib/makefile.in: added abs.c and labs.c
5131 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5133 * device/include/stdint.h: added
5134 * device/lib/abs.c: added
5135 * device/lib/labs.c: added
5136 * device/include/stdlib.h: added abs() and labs() prototypes
5137 * device/lib/libsdcc.lib: added abs and labs
5138 * device/include/float.h,
5139 * device/lib/_fsmul.c,
5140 * device/lib/printf_fast.c,
5141 * device/lib/printf_tiny.c: updated comments
5143 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5145 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5148 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5150 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5151 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5153 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5155 * device/lib/printf_large.c: removed inline assembly for portability and
5156 readability. Use printf_fast if speed or size are more important.
5157 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5158 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5160 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5162 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5163 prevent compiler warning
5165 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5167 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5168 moved to level 0 and declared as static. Also they are explicit
5169 placed in access bank. This was necessery because some times they
5170 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5171 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5172 optimizations. Currently only compare to unsigned char is implemented,
5173 * src/pic16/gen.c: added fReturnIdx array,
5174 * (struct resolvedIfx) is moved to gen.h and made public,
5175 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5176 * (aopForSym): added an optimization to directly store in stack of
5177 the operand of a SEND iCode,
5178 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5179 but as registers instead (AOP_REG) using the fReturnIdx array,
5180 * (pic16_freeAsmop): remove the freed register from the
5181 _G.sregsAlloc field,
5182 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5183 a compare of 'WREG',
5184 * (pic16_popGetTempRegCond): changed function prototype, now
5185 function takes also a bitVector argument v which holds the current
5186 set of registers that are allocated for stack access by aopForSym,
5187 registers allocated in aopForSym for accessing stack symbols are not
5188 any more part of the functions usedRegs field,
5189 * (genCall): some times aopOp is called for a stack variable to be
5190 send, aopForSym might perform the push, if this is true make sure
5191 that genCall doesn't push the variable twice by testing _G.resDirect,
5192 * (genFunction): changed testing for unspecified interrupt number
5193 from 256 to INTNO_UNSPEC,
5194 * modified selection scheme of frame pointer generation. Previously
5195 if function did use local registers a frame pointer was generated,
5196 now a frame pointer is generated only if function has arguments
5197 (that need PLUSW2 register access), or has stack arguments, or the
5198 compiler is not instructed to omit the frame pointer,
5199 * (genEndFunction): before restoring local registers that were saved
5200 in the function preamble, also restore the registers that *might*
5201 have been allocated for stack access,
5202 * (genRet): removed some old comments,
5203 * (genCmp, the active (RN's) version): added a call to the
5204 pic16_genCmp_special function to perform the compare with a more
5205 robust and optimized way,
5206 * (genInline): a feature has been added in inline code generation,
5207 which allows a wildcard variable substitution when writing inline
5208 assembly. Code is incomplete and experimental therefore undocumented,
5209 * (genCast): changed order of aopOp for result and right to allow
5210 aopForSym to directly load the result if possible,
5211 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5212 perform an optimized compare on some selected special occasions,
5213 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5214 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5215 generate an IVT any more,
5216 * src/pic16/main.c (pic16_optionsTable): added command line option
5218 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5219 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5221 * src/pic16/NOTES: Raphael Neider added in list of active developers
5222 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5223 jumptable_end to prevent bug #,
5224 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5225 inCond and outCond fields,
5226 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5227 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5228 turn off register spilling,
5229 * (packRegsForOneUse): synced with other ports' versions although it
5230 is not used currently,
5231 * (pic16_packRegisters): added an optimization while reading
5232 structure bitfields, some registers may be saved (malloc code is
5233 decreased by 80 bytes)
5235 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5237 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5238 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5239 this can be optimized more?
5241 2005-03-10 Raphael Neider <rneider AT web.de>
5243 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5244 genNearPointerGet): (hopefully) fixed access to bitfields via
5245 pointers (p->bitN = x; and x = p->bitN; failed)
5247 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5435 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5436 this might fix SIGSEGVs on MinGW...

5881 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5882 Now 4 algorithms for mcs51 jumptable generation are used:
5883 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5915 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5917 * added libc directory. The current version of LibC contains string
5918 functions, ctype functions and macros and some functions of the
5919 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5920 be extensively tested in the future. Standard disclaimer here.
5921 Library is not automatically build yet. But one can build it by
5922 invoking 'make' inside the libc directory.

5933 * (pic16_storeForReturn): optimized return of 0,
5934 * (genCmp): experimental code for new genCmp which uses PIC18's
5935 special compare&skip instructions. Initial tests fail some times
5936 with variables grater than 1 byte in size, so new code is disabled,
5937 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5939 * (genCast): began a fix to optimize the casting of a bit to another
5940 bit, now assigning a bitfield to another bitfield will fail, sorry,

5949 and 1 for banking instruction,
5950 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5951 caused stop processing pCodes after a inline assembly block,
5952 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5954 registers when it shouldn't,
5955 * src/pic16/ralloc.c (allocReg): add preliminary support for
5956 supporting a limited set of temporary registers,
5958 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5960 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5961 genDataPointerSet): ensure assignments always copy in MSB to LSB
5963 (loadRegFromAop): recognize CLRH optimization,
5964 (genFunction): optimize RECEIVE iCodes in reentrant functions
5966 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5968 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5977 * device/lib/_gptrget.c (_gptrget),
5978 * device/lib/_gptrgetc.c (_gptrgetc),
5979 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5980 instead of sjmp to ret
5981 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided

8963 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8965 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8966 loaded with the linker search paths (-L arguments) and the libraries
8967 to be linked with the current source (-l arguments). Changes
8968 currently will affect only the pic16 port.
8969 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8970 include path the port specific paths and port specific libraries,
8971 * gplink command now contains the $3 argument,
8972 * src/pic16/device.h,
8973 * src/pic16/device.c,: structure PIC_device is made public and
8974 renamed to PIC16_device, the same for variable Pics which is renamed

8989 Documenting changes from previous commits.
8990 * configure.in (version 1.56),
8991 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8992 when generating output files to configure the pic16 library,
8993 but now I've commented it out, since gputils aren't installed in the
8994 SF compile farm, so library won't compile
8996 * device/lib/Makefile.in (version 1.56): initially I've added in
8997 target 'all' the prerequestive 'model-pic16' so it compiled the
8998 pic16 library, but now I've commented it out for the same reasons
9000 * added targets 'model-pic16' and 'objects-pic16' to compile the
9002 * added target 'port-specific-objects-pic16' to handle the
9003 generated libraries and copy them into the build/ directory
9004 * added target 'clean-intermediate-pic16' to clean intermediate
9005 files into pic16 directory
9006 * in target 'installdirs' added line to create directory pic16 in
9007 the installation path

9010 added lines to copy all header files to installation path,
9011 * in target 'installdirs' added line create directory for pic16
9012 headers in the installation path

9028 option so that it actually works. Made it specific to the z80, since
9029 the gbz80 doesn't have these kinds of I/O ports.
9031 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9033 * device/include/z180.h,

9057 via literal number. The symbol is placed in the corresponding
9058 position of the data ram
9059 * (pic16_dump_section): relocatable and absolute uninitialized
9060 data are now emitted in sorted order to reduce section naming,
9061 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9062 weren't marked as being in the access bank,
9064 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9066 Added portion of GNU PIC Library under the directory
9067 device/include/pic16 and device/lib/pic16. These files
9068 contain the declarations of SFRs for the PIC18Fxx2 devices.
9069 The directory is initialized via configure from toplevel.

9100 to better keep the right margin. Changed some notes about
9101 maintainance of the ports in section 3.2.1 - is it OK like this?
9103 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9140 UPPER for immediate operands,
9141 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9143 * src/pic16/peeph.def: all peepholes with movff are commented out,
9144 because there is a problem in the pcode peep optimizer,
9145 * src/pic16/ralloc.c: the register allocator can now reuse local

9255 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9257 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9258 (default behaviour).
9260 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9262 A python script to validate compiler diagnostic messages. It can be
9263 used to verify that sdcc complains about bad c source code and
9264 gives a good location of the error.
9265 * support/valdiag/Makefile,
9266 * support/valdiag/valdiag.py,

9286 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9288 * sdcc.spec: updated
9289 * device/include/Makefile.in: don't install CVS directories
9290 * device/lib/Makefile.in: added removal of CVS directories after install
9291 * doc/Makefile: fixed install, added local_icons
9292 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9293 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9294 * src/ds390/gen.c (genRightShift): fixed bug #870788

9297 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9299 PIC16 port related changes:
9300 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9301 added variable stackPos,
9303 * gen.c: genCall, assignResultValue: added support for
9304 pushing/retrieving function parameters to/from stack,
9305 genFunction,genEndFunction: setup stack frame for the
9307 genAddrOf: will be changed according to bug 863624
9309 * added files genutils.c and genutils.h which contain gen*
9310 debugged and optimised functions extracted from gen.c
9312 * glue.c: added variable 'externs' which holds extern symbols,
9313 pic16emitRegularMap: is modified to properly handle relocatable
9314 symbols under the new scheme,
9315 pic16createInterruptVect: is modified
9316 pic16printPublics: is modified to emit 'global' assembler directives,
9317 added pic16_printExterns to print extern symbols,
9318 pic16glue: initializes stack/frame pointer in the beginning of
9319 the assembly output. Temporary hack, will be corrected later,
9320 because gplink yet does not support stack and SDCC does not
9321 yet support a type of crt0.o object to create the final binary.
9323 * Removed many lines that contain 8051 legacy code.
9324 * The code is finally placed under a 'code' directive.
9325 * Added port specific options.
9327 * _process_pragma: simplified since now we do not need *special*
9328 include file to define SFR registers. But a separate header
9329 will be needed. This will be developed later.
9330 * _pic16_parseOptions: added, parses port specific options:
9331 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9332 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9333 --preplace-udata-with=
9335 * _pic16_setDefaultOptions: modified to initialize section names,
9336 but hack is temporarly out of order since it needs improvement.
9337 * _pic16_genAssemblerPreamble: configuration words are emitted by
9338 their address instead of their name. This part is incomplete and
9339 supports only the 18Fxx2 devices. Other devices will emit an error
9340 during assembly since they do not contain the same set of config
9342 * _pic16_genIVT: is modified,
9344 * pcode.c: added definitions for some hardware registers that are needed
9346 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9347 All PCI entries are updated. Now LFSR is supported.
9348 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9349 * added pic16_newpCodeOpLit2 to support instructions with
9350 two literal arguments
9351 * pic16_pCode2str: corrected code that emits assembler instructions
9352 with two literal operands and those that have an access bit modifier
9353 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9354 this fixes a bug which caused some labels to be lost, when an
9355 assembler directive was added, i.e. banksel,
9356 * pic16_FixRegisterBanking: improved logic that causes the insertion
9358 * InlineFunction: functions that are called once, are not any more
9359 inlined. This can be a port option in the future,
9361 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9363 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9364 hold the corresponding uninitialized symbols,
9365 * pic16_allocProcessorRegister: registers have explicit marked the
9367 * pic16_allocInternalRegister: registers are explicit marked as
9369 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9370 processing list, so bit registers were lost,
9373 * ralloc.h: added field 'accessBank' and original symbol operand
9374 in register definition,
9375 * removed the field isMapped from register definition,
9377 ** Several functions have been removed from various sources:
9378 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9379 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9380 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9381 pic16_assignRelocatableRegisters
9383 ** others have been introduced:
9384 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9385 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9387 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9389 * support/scripts/inc2h.pl: changed definition of BIT_AT
9390 to emit 'sbit at' instead of 'bit at'. This was a request.
9392 PIC16 port related preliminary changes:
9393 * gen.c: prefixed function popRegFromString with
9394 pic16_ and all references to it corrected
9395 * pcode.c: all pic16_pc_* hardware registers prefixed
9396 with underscore (_),
9397 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9398 * ralloc.c: newReg(): when register is REG_SFR then
9399 set address to rIdx,
9400 pic16_allocProcessorRegister(): marks register wasUsed=0
9401 pic16_writeUsedRegs(): added a call to assign processor
9402 registers via pic16_assignFixedRegisters
9404 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9406 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9407 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9408 variables in unused register banks. Also the SSEG is placed
9409 wherever there is enough space for it, and IDATA can be anywhere
9410 in internal RAM. For now compile using -Wl-Y[stack_size].
9411 The mem file is different for this option as well, since it
9412 makes no sense of talking about DSEG lenght.
9414 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9416 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9417 in certain cases, e.g. when ROM assignment, patch provided
9418 from Albert den Haan.
9420 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9563 * src/mcs51/peephole.def,
9564 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

10305 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10306 support for standard C idiom of memory mapped variables; for

10326 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10328 Fixed bug #621531 (const & volatile confusion in the type chain).
10329 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10330 refer to the const or volatile state of the pointer itself.

10409 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10410 iCode properly now. Use getSize instead of nRegs since a & b
10411 aren't part of the nRegs tally.
10413 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10415 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10427 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10428 If they pop r0/r1 they must be called in the opposite order than aopOp().
10429 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10430 (resp. --stack-auto), prepared for --xstack

10443 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10444 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10445 type for bits was changed. It resulted in bit variables becoming
10446 global, which is not permitted in PIC 14 assembly output.
10448 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10450 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10452 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10454 Z80 and MCS51 linkers complaint if a public symbol is defined

10461 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10463 A few small changes that speed up the peephole optimizer.
10467 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10469 Try to make the peephole optimizer smarter by maintaining
10470 an association between the assembly source code and the
10471 iCodes that originated them. Put this information to use
10472 with a new peephole rule condition "notVolatile" so that
10473 the rules can be aggressive yet still safe.
10478 * src/mcs51/peeph.def
10480 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10484 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10485 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10486 if the left or right operand symbols have the accuse flag set.
10488 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10490 Changed the type of the result of the ! (NOT) operator to char;
10491 previously it returned the same type as the source. This allows
10492 us to eliminate all the genFloatNot functions (all of its target
10493 implementations were very buggy) since !float can use the same
10496 * src/SDCCicode.c (ast2iCode): ! returns char

10505 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10506 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10507 during interrupts. Ensure WSAVE is located at a shared bank address.
10508 2. Fixed page selection in some places
10509 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10510 the registers name strings.
10511 4. Fixed "signed / unsigned compare" compiler warnings.
10512 5. The PIC port manages its own allocation of the general purpose
10513 registers, but makes no attempt to reuse them. As a result when
10514 compiling it soon runs out of general purpose registers. Some
10515 additional code was added to the files pcode.c and device.c to walk
10516 through the function call tree and rename the registers so that they
10526 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10527 genPlus() & genMinus() when the result is the same as left or right

10533 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10535 Made bitfield a distinct type from bit so that bitfields
10536 convert as per ANSI C and bits retain their traditional
10537 boolean style behaviour. Implemented bitfield support in
10545 * src/ds390/gen.c: bit v bitfield split
10546 * src/z80/gen.c: New support for bitfields
10547 * support/regression/tests/bitfields.c: reenabled z80,
10550 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10552 Rules 246.x, 247.x relate to bitfields, the others speed up
10553 access to xdata mapped I/O devices.
10555 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10557 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10559 Cleaned up genPackBits and genUnpackBits and added two helper
10560 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10561 for literal assignments in genPackBits (thanks to Frieder for
10567 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10569 Fixed bug #748310 (pointer to function type mishandled when the
10570 function name is omitted). Also fixed a SIGSEGV when a function
10571 attribute (reentrant, etc) is used on a non-function or on a
10572 function but misplaced before the parameter list.
10574 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10576 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10577 * support/Util/SDCCerr.h,
10578 * support/Util/SDCCerr.c: Added func attr misuse error msg

10599 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10601 Made the constant following the "interrupt" keyword optional. If
10602 omitted, the function will not automatically be given an entry
10603 in the interrupt vector table (similar to #pragma NOIV, but
10604 less syntacticly kludgy). The interrupt number is also now
10605 range checked. Also fixed a bug in the high order bit example

10624 be re-activated by defining REDUCE_LITERALS)
10625 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10626 unsigned, but are signed by default
10627 * src/SDCCval.c (constVal): rearranged
10628 * src/SDCCval.c (valMod): preliminary fix

10671 constants are unsigned; added recognition of "u" flag for unsigned
10672 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10673 * src/SDCCval.c (valDiv, valMod): fixed signdness
10674 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10675 signedness of modulo, left and right shift

11123 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
11125 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11126 it can be defined with CFLAGS when running configure
11127 * src/SDCCmain.c: fixed compiling + linking with object files
11129 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
11131 * configure.in: configure for pic16 port,
11132 added --disable-pic16-port
11133 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
11134 * src/SDCCmain.c: linkOptions is changed to set *,
11135 added if/endif conditional macros to remove options help
11136 messages from optionsTable when a port is not configured, added
11137 support for the PIc16 port in the ports table, when executing
11138 the compiler with no port specified on command line, a default
11139 port is selected with the new macro DEFAULT_PORT which is
11140 defined in port.h, in setDefaultOptions() linkOptions is removed
11141 from initialization assignment, since now it is a set,
11142 parseCmdLine uses setParseWithComma for linkOptions, in
11143 linkEdit() linkOptions are accessed with new function indexSet()
11144 which returns the i'th item of a set variable. See SDCCset.c, in
11145 linkEdit() when calling buildCmdLine(), added linkOptions as
11146 last argument. Now users can pass arguments to gplink via the
11147 -Wl option, main() uses pic16glue() to glue up pic16 programs
11148 * src/SDCCpeeph.c: various changes to support pic16
11149 * src/SDCCset.c: added function void *indexSet(set *, int) to

11159 * src/pic16/glue.c: commented out some error producing lines
11160 * src/pic16/main.c: __config directives are commented out to stop
11161 gpasm complaining and test the linkage with gplink, _linkCmd and
11162 _asmCmd changed to be more gplink and gpasm friendly
11163 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11164 produced an error when parsed, peep rule 12 is added to utilize
11165 movff, but it is commented out since the pCode does not support
11166 yet a command with 2 address arguments

12218 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12219 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12226 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12228 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12229 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12231 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12233 * in /sdcc/as/mcs51/ changed these files in order to create an
12234 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12235 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12236 following files to include the previous two files: aslink.dsp,
12237 Makefile.aslink, Makefile.bcc, and Makefile.in.
12239 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12240 .adb instead of .cdb
12242 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12244 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12245 value from option --iram-size.
12247 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12249 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12252 2002-09-18 <wiml AT hhhh.org>
12254 * SDCClrange.h: exposed setFromRange() and setToRange()
12255 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12256 packRegsForAccUse() (bug 542397)
12257 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12258 multiple times and emitting the fetch operations more than once
12259 added aopGetUsesAcc() function to allow binary operators to
12260 fetch their operands in the correct order; made genMinus() emit
12261 compact code for X = LITERAL - Y
12263 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12264 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12265 sprintf() in line 1267.
12267 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12268 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12271 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12272 Changes to aslink (All the changes are marked with 'JCF'):
12274 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12277 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12278 area BSEG. Also moves, if possible, the DATA area down into the internal
12279 ram so more space is available.
12281 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12284 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12285 not bytes. Function summary() which creates a memory usage summary
12286 file with extension .mem. Reports of overlaping stack and small stack
12287 size. If the space for the stack is less than 16 bytes aslink trows a
12290 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12291 the 8051. Option 'y' for memory summary output file.
12293 Changes to sdcc (All the changes are marked with 'JCF'):
12295 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12297 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12298 overlaying area for it (uses RegBankUsed[4]).
12300 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12301 bank zero as used by default. By default aslink locates the stack
12302 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12303 the creation of the .mem file. Delegates the allocation of data area
12304 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12305 the begining of the stack area to aslink.
12307 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12308 glue() in SDCCglue.c creates an area for it.
12310 2002-09-03 Borut Razem <borut.razem AT siol.net>
12311 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12312 sdcc/src/pic/glue.c:
12313 introduced atexit() handler for teporay files removal in case of
12314 errors, assertions, ...
12316 2002-08-29 Borut Razem <borut.razem AT siol.net>
12317 * sdcc/support/cpp2/auto-host_vc_in.h:
12318 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12319 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12320 Maybe there is a similar problem with BORLANDC? It should be checked!
12322 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12323 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12324 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12325 was not executed, and the compiler (cl) launched a warning:
12326 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12328 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12329 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12331 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12332 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12334 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12335 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12336 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12337 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12338 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12339 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12340 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12341 - added Release configuration in VS projects
12342 - review of compiler an linker options
12343 - VC .exe files are generated in bin_vc directory, not to interfere
12344 with binaries generated from other projects (cygwin, mingw, bcc ...)
12346 * sdcc/src/yacc.dsp: added
12348 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12349 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12350 and insert the version number definitions from .version
12352 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12354 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12355 added - genarate auto-host.h using auto-host_vc_in.h as template
12358 removed from CVS, generated automatically
12360 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12361 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12363 2002-08-11 Borut Razem <borut.razem AT siol.net>
12364 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12366 2002-08-10 Borut Razem <borut.razem AT siol.net>
12367 * src/SDCCmain.c (main):
12368 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12369 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12370 The consequence was that some temporary files were not removed.

12582 Previous fix was not good. basic blocks that have "break" or "return" are
12583 not really partof a loop , but live ranges used in these blocks should
