3452 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3454 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3455 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3457 One basic decision: e.g. src/clean.mk includes further files. In order
3458 to make this work there are two solutions:
3459 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3460 run configure on them. This way they can use
3461 'include $(srcdir)/port-clean.mk'
3462 - always include clean.mk by the Makefile at the same level. To avoid
3463 that `make clean` tries to include and build Makefile.dep the
3464 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3465 implemented, because now even `make uninstall` doesn't create
3466 Makefile.in. clean.mk could be eliminated by pasting it in
3469 * debugger/mcs51/Makefile.in: build own objects from library sources
3470 (SLIB, SDCC) in current directory
3472 * configure, configure.in: renamed --disable-device-lib-build in
3473 --disable-device-lib; added --enable-doc, the required tools are
3474 searched by configure; added result message; the toolchain for the
3475 belonging ports are now only built, if the port is enabled.
3477 * support/regression/*: all output is written in directory gen, because
3478 the fwk and ports directories don't livet in the build tree using vpath
3480 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3481 --disable-device-lib, added --enable-doc, added section VPATH

3735 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3737 * src/mcs51/gen.c (genCall): fixed bug 1457608
3739 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3758 implemented patch 1120823 Thanks to Willy De la Court (normal
3759 interrupts need an interrupt number now if they are made critical),
3760 and enabled nesting of critical functions though not for gbz80
3761 (genCritical, genEndCritical): added functions
3762 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3763 * src/z80/mappings.i: added "ei" to all mappings

3772 2006-03-16 Raphael Neider <rneider AT web.de>
3774 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3775 the left operand is shorter than the result (c* = lit-c* + int),
3777 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3780 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3782 * src/.version: increased version number to 2.5.5
3783 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3784 linking is done manually in pic16 port's _linkEdit,
3785 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3786 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3787 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3788 allocate asmop as AOP_ACC,
3789 (aopForRemat): added parameter 'bool result' in function declaration,
3790 (pic16_aopGet): return AOP_ACC when accessing WREG,
3791 (pic16_popGetTempReg): minor modification,

3802 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3803 call to allocReg, not by manually allocating a new one,
3804 (pic16_assignRegisters): now before going through the register
3805 allocating functions mark all registers as free. This eliminates some
3806 side effects resulting from peephole parser done earlier in the backbone
3808 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3858 2006-03-06 Borut Razem <borut.razem AT siol.net>
3860 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3861 made the linker quiet
3863 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3865 * src/pic16/gen.c (genPcall): fixed bug #1443644
3866 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3867 which dumps before the function entry point a data byte which represents
3868 the number of the local variables used by the specified function, added
3869 'xinst' for initial support for Extended Instruction Support,
3870 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3871 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3872 port->fun_prefix anymore (may change later),
3873 (genFunction, genEndFunction): do not store/restore local registers for
3874 _main (this should take care the --main-return command line option in
3876 (genOr): removed some legacy pic-port instructions,
3877 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3878 performing operations with SFR's causes data to be written more than
3879 once to each SFR. Perhaps SFRs should be handled in special cases...
3880 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3882 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3883 into account for stack starting position,
3884 (struct OPTIONS pic16_optionsTable): added command line argument
3885 --extended or -y for Extended Instruction Support,
3886 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3887 (deassignLRs): *** perhaps the most important change, old 'for' code
3888 (commented out for reference), didn't account for some registers which
3889 were left marked 'not free' after a pointer operation. The change
3890 reduces register usage a lot in some cases
3892 2006-03-04 Borut Razem <borut.razem AT siol.net>
3894 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3900 2006-03-03 Borut Razem <borut.razem AT siol.net>
3902 * support/regression/fwk/lib/testfwk.c,

6165 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6166 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6167 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6168 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6169 always available in leading double underscore form. The C99 support is
6170 mostly missing, but it's a start.
6171 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6172 reserved identifier "__data".

6250 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6252 * device/lib/printf_large.c: removed inline assembly for portability and
6253 readability. Use printf_fast if speed or size are more important.
6254 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6255 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6257 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6259 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6260 prevent compiler warning
6262 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6264 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6265 moved to level 0 and declared as static. Also they are explicit
6266 placed in access bank. This was necessery because some times they
6267 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6268 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6269 optimizations. Currently only compare to unsigned char is implemented,
6270 * src/pic16/gen.c: added fReturnIdx array,
6271 * (struct resolvedIfx) is moved to gen.h and made public,
6272 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6273 * (aopForSym): added an optimization to directly store in stack of
6274 the operand of a SEND iCode,
6275 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6276 but as registers instead (AOP_REG) using the fReturnIdx array,
6277 * (pic16_freeAsmop): remove the freed register from the
6278 _G.sregsAlloc field,
6279 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6280 a compare of 'WREG',
6281 * (pic16_popGetTempRegCond): changed function prototype, now
6282 function takes also a bitVector argument v which holds the current
6283 set of registers that are allocated for stack access by aopForSym,
6284 registers allocated in aopForSym for accessing stack symbols are not
6285 any more part of the functions usedRegs field,
6286 * (genCall): some times aopOp is called for a stack variable to be
6287 send, aopForSym might perform the push, if this is true make sure
6288 that genCall doesn't push the variable twice by testing _G.resDirect,
6289 * (genFunction): changed testing for unspecified interrupt number
6290 from 256 to INTNO_UNSPEC,
6291 * modified selection scheme of frame pointer generation. Previously
6292 if function did use local registers a frame pointer was generated,
6293 now a frame pointer is generated only if function has arguments
6294 (that need PLUSW2 register access), or has stack arguments, or the
6295 compiler is not instructed to omit the frame pointer,
6296 * (genEndFunction): before restoring local registers that were saved
6297 in the function preamble, also restore the registers that *might*
6298 have been allocated for stack access,
6299 * (genRet): removed some old comments,
6300 * (genCmp, the active (RN's) version): added a call to the
6301 pic16_genCmp_special function to perform the compare with a more
6302 robust and optimized way,
6303 * (genInline): a feature has been added in inline code generation,
6304 which allows a wildcard variable substitution when writing inline
6305 assembly. Code is incomplete and experimental therefore undocumented,
6306 * (genCast): changed order of aopOp for result and right to allow
6307 aopForSym to directly load the result if possible,
6308 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6309 perform an optimized compare on some selected special occasions,
6310 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6311 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6312 generate an IVT any more,
6313 * src/pic16/main.c (pic16_optionsTable): added command line option
6315 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6316 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6318 * src/pic16/NOTES: Raphael Neider added in list of active developers
6319 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6320 jumptable_end to prevent bug #,
6321 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6322 inCond and outCond fields,
6323 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6324 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6325 turn off register spilling,
6326 * (packRegsForOneUse): synced with other ports' versions although it
6327 is not used currently,
6328 * (pic16_packRegisters): added an optimization while reading
6329 structure bitfields, some registers may be saved (malloc code is
6330 decreased by 80 bytes)
6332 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6334 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6335 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6336 this can be optimized more?
6338 2005-03-10 Raphael Neider <rneider AT web.de>
6340 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6341 genNearPointerGet): (hopefully) fixed access to bitfields via
6342 pointers (p->bitN = x; and x = p->bitN; failed)
6344 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6388 to keep the correct label reference count when adding/removing references
6389 to labels. A peephole file using this is appended to patch #1144962.

6976 Adding support for replacing ljmps with sjmps in jumptables
6977 generated for switch statements. For now you need to set the
6978 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6979 Now 4 algorithms for mcs51 jumptable generation are used:
6980 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6981 addresses loaded pc-relative for up to 112 cases and stack-pushing
6982 target addresses loaded with offset from dptr for up to 256 cases.

7012 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7014 * added libc directory. The current version of LibC contains string
7015 functions, ctype functions and macros and some functions of the
7016 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7017 be extensively tested in the future. Standard disclaimer here.
7018 Library is not automatically build yet. But one can build it by
7019 invoking 'make' inside the libc directory.

7030 * (pic16_storeForReturn): optimized return of 0,
7031 * (genCmp): experimental code for new genCmp which uses PIC18's
7032 special compare&skip instructions. Initial tests fail some times
7033 with variables grater than 1 byte in size, so new code is disabled,
7034 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7036 * (genCast): began a fix to optimize the casting of a bit to another
7037 bit, now assigning a bitfield to another bitfield will fail, sorry,

7046 and 1 for banking instruction,
7047 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7048 caused stop processing pCodes after a inline assembly block,
7049 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

7051 registers when it shouldn't,
7052 * src/pic16/ralloc.c (allocReg): add preliminary support for
7053 supporting a limited set of temporary registers,
7055 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9966 * support/regression/generate-cases.py (main): Changed from inline
9969 * doc/Makefile (install): Changed to depth first to get rid of
9970 missing directory install warning.
9972 * as/Makefile (install-doc): Made work on Mac.
9974 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9976 * src/SDCCast.c: added an additional type flow in decorateType() of
9977 opposite direction, see feature request #860006; it's enabled at runtime
9978 by setting the environment variable SDCC_NEWTYPEFLOW
9979 * src/SDCCast.h: changed prototype of decorateType()
9980 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
9981 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
9982 'char' to 'int' can be omitted, if both operands are 'unsigned char';
9983 see feature request #877103
9984 * src/SDCCval.c: updated call of decorateType()
9985 (valBitwise): fixed bug #882876
9986 (valMinus): added promotion
9987 (valLogicAndOr): result is unsigned
9988 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
9989 * src/SDCCsymt.c (computeType),
9990 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
9991 must not cause an unsigned operation
9992 * src/pic/glue (pic14emitRegularMap),
9993 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
9995 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
9997 * src/pic/pcode.c (PCodeID): commented out left over debug code

10012 * src/pic/ralloc.h: applied patch from Slade Rich;
10013 added support for multiple code pages and multiple RAM banks on the
10014 PIC 14 port. The ASM files now no longer simply assume all the
10015 code / RAM are in the same page / bank. This means the linker can
10016 safely allocate code/RAM of separate ASM files to different pages/banks.
10017 * doc/sdccman.lyx: added Slade's tips
10018 * src/mcs51/peeph.def: fixed bug #880768

10030 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
10031 strtof is not part of C89 and isn't included with Mac OS X.
10033 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10035 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

10060 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10062 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10063 loaded with the linker search paths (-L arguments) and the libraries
10064 to be linked with the current source (-l arguments). Changes
10065 currently will affect only the pic16 port.
10066 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10067 include path the port specific paths and port specific libraries,
10068 * gplink command now contains the $3 argument,
10069 * src/pic16/device.h,
10070 * src/pic16/device.c,: structure PIC_device is made public and
10071 renamed to PIC16_device, the same for variable Pics which is renamed
10072 to Pics16. Updated all references to them.
10073 * src/pic16/glue.c (pic16glue): corrected bug with code
10074 initialization which bypassed the variable initializations block.
10076 * device/lib/pic16/Makefile.rules: removed --penable-stack from
10077 COMPILE_FLAGS and added the --nostdinc option

10084 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10086 Documenting changes from previous commits.
10087 * configure.in (version 1.56),
10088 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10089 when generating output files to configure the pic16 library,
10090 but now I've commented it out, since gputils aren't installed in the
10091 SF compile farm, so library won't compile
10093 * device/lib/Makefile.in (version 1.56): initially I've added in
10094 target 'all' the prerequestive 'model-pic16' so it compiled the
10095 pic16 library, but now I've commented it out for the same reasons
10097 * added targets 'model-pic16' and 'objects-pic16' to compile the
10099 * added target 'port-specific-objects-pic16' to handle the
10100 generated libraries and copy them into the build/ directory
10101 * added target 'clean-intermediate-pic16' to clean intermediate
10102 files into pic16 directory
10103 * in target 'installdirs' added line to create directory pic16 in
10104 the installation path
10106 * device/include/Makefile.in (version 1.11): in target 'install'
10107 added lines to copy all header files to installation path,
10108 * in target 'installdirs' added line create directory for pic16
10109 headers in the installation path

10122 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10124 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10125 option so that it actually works. Made it specific to the z80, since
10126 the gbz80 doesn't have these kinds of I/O ports.
10128 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10130 * device/include/z180.h,

10154 via literal number. The symbol is placed in the corresponding
10155 position of the data ram
10156 * (pic16_dump_section): relocatable and absolute uninitialized
10157 data are now emitted in sorted order to reduce section naming,
10158 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10159 weren't marked as being in the access bank,
10161 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10163 Added portion of GNU PIC Library under the directory
10164 device/include/pic16 and device/lib/pic16. These files
10165 contain the declarations of SFRs for the PIC18Fxx2 devices.
10166 The directory is initialized via configure from toplevel.
10168 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10170 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10171 the spilllocations to be compared correctly
10173 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10175 * src/SDCCast.c (decorateType): fixed bug introduced today
10177 2004-01-12 Borut Razem <borut.razem AT siol.net>

10195 * doc/sdccman.lyx: Moved and added some sections, small changes
10196 all over. Telling LaTeX to be less strict with word spacing
10197 to better keep the right margin. Changed some notes about
10198 maintainance of the ports in section 3.2.1 - is it OK like this?
10200 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

10240 * src/pic16/peeph.def: all peepholes with movff are commented out,
10241 because there is a problem in the pcode peep optimizer,
10242 * src/pic16/ralloc.c: the register allocator can now reuse local
10243 function symbols for another function. This saves register usage.

10359 A python script to validate compiler diagnostic messages. It can be
10360 used to verify that sdcc complains about bad c source code and
10361 gives a good location of the error.
10362 * support/valdiag/Makefile,
10363 * support/valdiag/valdiag.py,
10364 * support/valdiag/tests/*

10377 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10379 * src/common.h: added ifndef/define/endif macros
10380 around the header file.
10381 Bug reported from Jesus Calvino-Fraga
10383 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10385 * sdcc.spec: updated
10386 * device/include/Makefile.in: don't install CVS directories
10387 * device/lib/Makefile.in: added removal of CVS directories after install
10388 * doc/Makefile: fixed install, added local_icons
10389 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
10390 * src/mcs51/gen.c (genRightShift): fixed bug #870788
10391 * src/ds390/gen.c (genRightShift): fixed bug #870788
10392 * src/SDCCast.c (decorateType): fixed bug #870781
10394 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10396 PIC16 port related changes:
10397 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10398 added variable stackPos,
10400 * gen.c: genCall, assignResultValue: added support for
10401 pushing/retrieving function parameters to/from stack,
10402 genFunction,genEndFunction: setup stack frame for the
10403 generated function,
10404 genAddrOf: will be changed according to bug 863624
10406 * added files genutils.c and genutils.h which contain gen*
10407 debugged and optimised functions extracted from gen.c
10409 * glue.c: added variable 'externs' which holds extern symbols,
10410 pic16emitRegularMap: is modified to properly handle relocatable
10411 symbols under the new scheme,
10412 pic16createInterruptVect: is modified
10413 pic16printPublics: is modified to emit 'global' assembler directives,
10414 added pic16_printExterns to print extern symbols,
10415 pic16glue: initializes stack/frame pointer in the beginning of
10416 the assembly output. Temporary hack, will be corrected later,
10417 because gplink yet does not support stack and SDCC does not
10418 yet support a type of crt0.o object to create the final binary.
10420 * Removed many lines that contain 8051 legacy code.
10421 * The code is finally placed under a 'code' directive.
10422 * Added port specific options.
10424 * _process_pragma: simplified since now we do not need *special*
10425 include file to define SFR registers. But a separate header
10426 will be needed. This will be developed later.
10427 * _pic16_parseOptions: added, parses port specific options:
10428 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10429 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10430 --preplace-udata-with=
10432 * _pic16_setDefaultOptions: modified to initialize section names,
10433 but hack is temporarly out of order since it needs improvement.
10434 * _pic16_genAssemblerPreamble: configuration words are emitted by
10435 their address instead of their name. This part is incomplete and
10436 supports only the 18Fxx2 devices. Other devices will emit an error
10437 during assembly since they do not contain the same set of config
10439 * _pic16_genIVT: is modified,
10441 * pcode.c: added definitions for some hardware registers that are needed
10443 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10444 All PCI entries are updated. Now LFSR is supported.
10445 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10446 * added pic16_newpCodeOpLit2 to support instructions with
10447 two literal arguments
10448 * pic16_pCode2str: corrected code that emits assembler instructions
10449 with two literal operands and those that have an access bit modifier
10450 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10451 this fixes a bug which caused some labels to be lost, when an
10452 assembler directive was added, i.e. banksel,
10453 * pic16_FixRegisterBanking: improved logic that causes the insertion
10455 * InlineFunction: functions that are called once, are not any more
10456 inlined. This can be a port option in the future,
10458 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10460 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10461 hold the corresponding uninitialized symbols,
10462 * pic16_allocProcessorRegister: registers have explicit marked the
10464 * pic16_allocInternalRegister: registers are explicit marked as
10466 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10467 processing list, so bit registers were lost,
10470 * ralloc.h: added field 'accessBank' and original symbol operand
10471 in register definition,
10472 * removed the field isMapped from register definition,
10474 ** Several functions have been removed from various sources:
10475 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10476 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10477 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10478 pic16_assignRelocatableRegisters
10480 ** others have been introduced:
10481 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10482 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10484 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10486 * support/scripts/inc2h.pl: changed definition of BIT_AT
10487 to emit 'sbit at' instead of 'bit at'. This was a request.
10489 PIC16 port related preliminary changes:
10490 * gen.c: prefixed function popRegFromString with
10491 pic16_ and all references to it corrected
10492 * pcode.c: all pic16_pc_* hardware registers prefixed
10493 with underscore (_),
10494 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10495 * ralloc.c: newReg(): when register is REG_SFR then
10496 set address to rIdx,
10497 pic16_allocProcessorRegister(): marks register wasUsed=0
10498 pic16_writeUsedRegs(): added a call to assign processor
10499 registers via pic16_assignFixedRegisters
10501 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10503 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10504 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10505 variables in unused register banks. Also the SSEG is placed
10506 wherever there is enough space for it, and IDATA can be anywhere
10507 in internal RAM. For now compile using -Wl-Y[stack_size].
10508 The mem file is different for this option as well, since it
10509 makes no sense of talking about DSEG lenght.
10511 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10513 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10514 in certain cases, e.g. when ROM assignment, patch provided
10515 from Albert den Haan.

10758 * src/SDCCast.c (decorateType): disabled a transformation I added in
10759 revision 1.188 (access to fields of a structure at an absolute address);
10760 it breaks with bitfields, extern declarations, and gcse analysis.
10761 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10762 could be assigned through a pointer, so don't complain.
10763 * src/SDCCast.c (astErrors),

11380 2003-09-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11382 * src/mcs51/gen.c (genFunction, genEndFunction),
11383 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11384 and restore of EA so that stack offsets to parameters are
11385 correct when using both critical and reentrant/stack-auto.
11386 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
11387 size (can be triggered in error if sloc is shared between
11388 different sized objects)

11400 * src/SDCCsymt.c (sclsFromPtr),
11402 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11403 support for standard C idiom of memory mapped variables; for
11404 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11405 to xdata int at 0x1234 tempvar = 1.
11406 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11407 provided by Akiya ISHIDA

11423 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11425 Fixed bug #621531 (const & volatile confusion in the type chain).
11426 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11427 refer to the const or volatile state of the pointer itself.
11439 * src/pic16/ralloc.c
11440 * support/regression/tests/const.c
11442 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11444 When checking for duplicated modules, use absolute paths
11445 instead of relative paths. Files changed:

11492 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11493 pcoderegs.h, ralloc.c, ralloc.h
11494 * main.c: added top header and GPL license notice

11497 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11499 * device/lib/_mullong.c: replaced int by short for gcc
11501 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11503 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11504 and JUMPTABLE iCodes properly now (worked by accident before)
11505 * src/mcs51/gen.c (leftRightUseAcc),
11506 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11507 iCode properly now. Use getSize instead of nRegs since a & b
11508 aren't part of the nRegs tally.
11510 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11512 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11521 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11522 copied from genNearPointerSet()
11523 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11524 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11525 If they pop r0/r1 they must be called in the opposite order than aopOp().
11526 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11527 (resp. --stack-auto), prepared for --xstack
11529 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11531 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11533 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11538 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11540 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11541 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11542 type for bits was changed. It resulted in bit variables becoming
11543 global, which is not permitted in PIC 14 assembly output.
11545 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11547 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11549 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11551 Z80 and MCS51 linkers complaint if a public symbol is defined
11552 in more than one library module:

11558 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11560 A few small changes that speed up the peephole optimizer.
11564 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11566 Try to make the peephole optimizer smarter by maintaining
11567 an association between the assembly source code and the
11568 iCodes that originated them. Put this information to use
11569 with a new peephole rule condition "notVolatile" so that
11570 the rules can be aggressive yet still safe.
11575 * src/mcs51/peeph.def
11577 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11581 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11582 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11583 if the left or right operand symbols have the accuse flag set.
11585 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11587 Changed the type of the result of the ! (NOT) operator to char;
11588 previously it returned the same type as the source. This allows
11589 us to eliminate all the genFloatNot functions (all of its target
11590 implementations were very buggy) since !float can use the same
11593 * src/SDCCicode.c (ast2iCode): ! returns char
11594 * src/mcs51/gen.c (genNot, genNotFloat),
11595 * src/ds390/gen.c (genNot, genNotFloat),
11596 * src/z80/gen.c (genNot, genNotFloat),
11597 * src/pic/gen.c (genNot, genNotFloat),
11598 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11600 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11602 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11603 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11604 during interrupts. Ensure WSAVE is located at a shared bank address.
11605 2. Fixed page selection in some places
11606 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11607 the registers name strings.
11608 4. Fixed "signed / unsigned compare" compiler warnings.
11609 5. The PIC port manages its own allocation of the general purpose
11610 registers, but makes no attempt to reuse them. As a result when
11611 compiling it soon runs out of general purpose registers. Some
11612 additional code was added to the files pcode.c and device.c to walk
11613 through the function call tree and rename the registers so that they
11623 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11624 genPlus() & genMinus() when the result is the same as left or right
11626 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11628 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11630 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11632 Made bitfield a distinct type from bit so that bitfields
11633 convert as per ANSI C and bits retain their traditional
11634 boolean style behaviour. Implemented bitfield support in
11642 * src/ds390/gen.c: bit v bitfield split
11643 * src/z80/gen.c: New support for bitfields
11644 * support/regression/tests/bitfields.c: reenabled z80,
11647 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11649 Rules 246.x, 247.x relate to bitfields, the others speed up
11650 access to xdata mapped I/O devices.
11652 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11654 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11656 Cleaned up genPackBits and genUnpackBits and added two helper
11657 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11658 for literal assignments in genPackBits (thanks to Frieder for
11664 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11666 Fixed bug #748310 (pointer to function type mishandled when the
11667 function name is omitted). Also fixed a SIGSEGV when a function
11668 attribute (reentrant, etc) is used on a non-function or on a
11669 function but misplaced before the parameter list.
11671 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11673 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11674 * support/Util/SDCCerr.h,
11675 * support/Util/SDCCerr.c: Added func attr misuse error msg
11677 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11679 Fixed bug #787649 by anonymous
11680 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11681 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11683 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11685 Fixed numerous bitfield problems.
11687 * src/SDCC.y: More bitfield related error checking

11694 * support/regression/tests/bitfields.c: tests added
11696 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11698 Made the constant following the "interrupt" keyword optional. If
11699 omitted, the function will not automatically be given an entry
11700 in the interrupt vector table (similar to #pragma NOIV, but
11701 less syntacticly kludgy). The interrupt number is also now
11702 range checked. Also fixed a bug in the high order bit example
11709 * support/Util/SDCCerr.c
11710 * support/Util/SDCCerr.h
11713 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11716 * src/SDCCicode.c (operandOperation): rewritten some ops
11717 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11718 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11720 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11721 be re-activated by defining REDUCE_LITERALS)
11722 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11723 unsigned, but are signed by default
11724 * src/SDCCval.c (constVal): rearranged
11725 * src/SDCCval.c (valMod): preliminary fix
11726 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11766 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11767 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11768 constants are unsigned; added recognition of "u" flag for unsigned
11769 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11770 * src/SDCCval.c (valDiv, valMod): fixed signdness
11771 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11772 signedness of modulo, left and right shift

12234 support for the PIc16 port in the ports table, when executing
12235 the compiler with no port specified on command line, a default
12236 port is selected with the new macro DEFAULT_PORT which is
12237 defined in port.h, in setDefaultOptions() linkOptions is removed
12238 from initialization assignment, since now it is a set,
12239 parseCmdLine uses setParseWithComma for linkOptions, in
12240 linkEdit() linkOptions are accessed with new function indexSet()
12241 which returns the i'th item of a set variable. See SDCCset.c, in
12242 linkEdit() when calling buildCmdLine(), added linkOptions as
12243 last argument. Now users can pass arguments to gplink via the
12244 -Wl option, main() uses pic16glue() to glue up pic16 programs

12258 gpasm complaining and test the linkage with gplink, _linkCmd and
12259 _asmCmd changed to be more gplink and gpasm friendly
12260 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12261 produced an error when parsed, peep rule 12 is added to utilize
12262 movff, but it is commented out since the pCode does not support
12263 yet a command with 2 address arguments

13326 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13328 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13330 * in /sdcc/as/mcs51/ changed these files in order to create an
13331 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13332 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13333 following files to include the previous two files: aslink.dsp,
13334 Makefile.aslink, Makefile.bcc, and Makefile.in.
13336 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13337 .adb instead of .cdb
13339 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13341 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13342 value from option --iram-size.
13344 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13346 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13349 2002-09-18 <wiml AT hhhh.org>
13351 * SDCClrange.h: exposed setFromRange() and setToRange()
13352 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13353 packRegsForAccUse() (bug 542397)
13354 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13355 multiple times and emitting the fetch operations more than once
13356 added aopGetUsesAcc() function to allow binary operators to
13357 fetch their operands in the correct order; made genMinus() emit
13358 compact code for X = LITERAL - Y
13360 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13361 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13362 sprintf() in line 1267.
13364 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13365 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13368 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13369 Changes to aslink (All the changes are marked with 'JCF'):
13371 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13374 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13375 area BSEG. Also moves, if possible, the DATA area down into the internal
13376 ram so more space is available.
13378 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13381 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13382 not bytes. Function summary() which creates a memory usage summary
13383 file with extension .mem. Reports of overlaping stack and small stack
13384 size. If the space for the stack is less than 16 bytes aslink trows a
13387 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13388 the 8051. Option 'y' for memory summary output file.
13390 Changes to sdcc (All the changes are marked with 'JCF'):
13392 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13394 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13395 overlaying area for it (uses RegBankUsed[4]).
13397 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13398 bank zero as used by default. By default aslink locates the stack
13399 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13400 the creation of the .mem file. Delegates the allocation of data area
13401 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13402 the begining of the stack area to aslink.
13404 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13405 glue() in SDCCglue.c creates an area for it.
13407 2002-09-03 Borut Razem <borut.razem AT siol.net>
13408 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13409 sdcc/src/pic/glue.c:
13410 introduced atexit() handler for teporay files removal in case of
13411 errors, assertions, ...
13413 2002-08-29 Borut Razem <borut.razem AT siol.net>
13414 * sdcc/support/cpp2/auto-host_vc_in.h:
13415 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13416 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13417 Maybe there is a similar problem with BORLANDC? It should be checked!
13419 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13420 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13421 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13422 was not executed, and the compiler (cl) launched a warning:
13423 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13425 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13426 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13428 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13429 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13431 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13432 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13433 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13434 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13435 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13436 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13437 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13438 - added Release configuration in VS projects
13439 - review of compiler an linker options
13440 - VC .exe files are generated in bin_vc directory, not to interfere
13441 with binaries generated from other projects (cygwin, mingw, bcc ...)
13443 * sdcc/src/yacc.dsp: added
13445 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13446 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13447 and insert the version number definitions from .version
13449 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13451 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13452 added - genarate auto-host.h using auto-host_vc_in.h as template
13455 removed from CVS, generated automatically
13457 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13458 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13460 2002-08-11 Borut Razem <borut.razem AT siol.net>
13461 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13463 2002-08-10 Borut Razem <borut.razem AT siol.net>
13464 * src/SDCCmain.c (main):
13465 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13466 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13467 The consequence was that some temporary files were not removed.
13470 unification of code in functions tempfilename() and tempfile():
13471 function tempnam() is defined in Visual Studio 6.0 and .NET
13473 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13475 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13476 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13477 - removed compiler command line option /WX: Treats all warnings as errors
13478 - update a list of source files, included into the project
13480 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13481 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13482 changed project type to Generic Project so that can be correcly converted to VS.NET project
13484 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13486 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13488 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13490 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13491 added return 0 statements after assert() to make compiler happy
13493 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13494 added newline in the def file to keep MSC compiler satisfied
13496 * sdcc/src/z80/gen.c:
13497 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13498 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13499 - solved MSC error in function aopDump()
13501 * sdcc_vc.h: define PREFIX as "\\sdcc"
13503 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

13552 Added -p option. Allows port dependent processor to be specified.
13555 Initialized the new field char *Processor field to NULL in all ports
13558 Compiler generated registers for interrupt context saving
13559 were not getting allocated.
13561 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13564 Fixed left shift. Will promote the left side of a left shift
13565 if a) left shifting more than size of operand or b) when assigned
13566 to something size > size of left side
13568 2002-03-14 Scott Dattalo <scott AT dattalo.com>

13679 Previous fix was not good. basic blocks that have "break" or "return" are
13680 not really partof a loop , but live ranges used in these blocks should
13681 be live thru the entire loop, so set partOfLoop but don't add them to
