314 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
316 Enabled VPATH feature: changed nearly all Makefiles (149 files).
317 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
319 One basic decision: e.g. src/clean.mk includes further files. In order
320 to make this work there are two solutions:
321 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
322 run configure on them. This way they can use
323 'include $(srcdir)/port-clean.mk'
324 - always include clean.mk by the Makefile at the same level. To avoid
325 that `make clean` tries to include and build Makefile.dep the
326 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
327 implemented, because now even `make uninstall` doesn't create
328 Makefile.in. clean.mk could be eliminated by pasting it in
331 * debugger/mcs51/Makefile.in: build own objects from library sources
332 (SLIB, SDCC) in current directory
334 * configure, configure.in: renamed --disable-device-lib-build in
335 --disable-device-lib; added --enable-doc, the required tools are
336 searched by configure; added result message; the toolchain for the
337 belonging ports are now only built, if the port is enabled.
339 * support/regression/*: all output is written in directory gen, because
340 the fwk and ports directories don't livet in the build tree using vpath
342 * doc/sdccman.lyx: renamed --disable-device-lib-build to
343 --disable-device-lib, added --enable-doc, added section VPATH
345 * sim/ucsim/configure.in,
346 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
347 z80 are enabled by default
349 2006-04-24 Raphael Neider <rneider AT web.de>
351 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
352 to config word, "pic14_"-prefixed some extern functions
353 (pic14_emitConfigWord): emit __config directive(s) if assignment to
354 config word has been found
355 * src/pic/device.h: added prototypes
356 * src/pic/pcode.c: added "pic14_"-prefix where needed
357 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
359 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
361 (pic14emitRegularMap): ignore config words,
362 (pic14createInterruptVect): moved generating __config directives away
363 (picglue): have __config directives emitted
365 2006-04-24 Borut Razem <borut.razem AT siol.net>
367 * doc/Makefile: sync with nightly build makefile
369 2006-04-24 Raphael Neider <rneider AT web.de>
371 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
372 registers that have not been assigned proper liveranges,
373 fixes #1469504 and #1474602,
374 (pCodeRegOptimizeRegUsage): fixed typo in comment
376 2006-04-24 Borut Razem <borut.razem AT siol.net>
378 * device/examples/main8051.c: deleted - it was removed from CVS

637 the left operand is shorter than the result (c* = lit-c* + int),
639 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
642 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
644 * src/.version: increased version number to 2.5.5
645 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
646 linking is done manually in pic16 port's _linkEdit,
647 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
648 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
649 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
650 allocate asmop as AOP_ACC,
651 (aopForRemat): added parameter 'bool result' in function declaration,
652 (pic16_aopGet): return AOP_ACC when accessing WREG,

664 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
665 call to allocReg, not by manually allocating a new one,
666 (pic16_assignRegisters): now before going through the register
667 allocating functions mark all registers as free. This eliminates some
668 side effects resulting from peephole parser done earlier in the backbone

728 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
729 which dumps before the function entry point a data byte which represents
730 the number of the local variables used by the specified function, added
731 'xinst' for initial support for Extended Instruction Support,
732 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
733 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
734 port->fun_prefix anymore (may change later),
735 (genFunction, genEndFunction): do not store/restore local registers for
736 _main (this should take care the --main-return command line option in
738 (genOr): removed some legacy pic-port instructions,
739 * src/pic16/genarith.c (genAddLit): re-enabled old code because
740 performing operations with SFR's causes data to be written more than
741 once to each SFR. Perhaps SFRs should be handled in special cases...
742 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
744 * src/pic16/main.c (_process_pragma): stack bound checking did not take
745 into account for stack starting position,
746 (struct OPTIONS pic16_optionsTable): added command line argument
747 --extended or -y for Extended Instruction Support,
748 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
749 (deassignLRs): *** perhaps the most important change, old 'for' code
750 (commented out for reference), didn't account for some registers which
751 were left marked 'not free' after a pointer operation. The change
752 reduces register usage a lot in some cases

3028 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3029 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3030 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3031 always available in leading double underscore form. The C99 support is
3032 mostly missing, but it's a start.
3033 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3034 reserved identifier "__data".
3036 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3078 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3079 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3080 immedDom() returning wrong block; probably fixes bug #1160833)
3082 2005-03-20 Borut Razem <borut.razem AT siol.net>
3084 * support/scripts/inc2h.pl: WIN32 port
3086 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3088 * device/lib/makefile.in: added abs.c and labs.c
3090 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3092 * device/include/stdint.h: added
3093 * device/lib/abs.c: added
3094 * device/lib/labs.c: added
3095 * device/include/stdlib.h: added abs() and labs() prototypes

3110 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3112 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3114 * device/lib/printf_large.c: removed inline assembly for portability and
3115 readability. Use printf_fast if speed or size are more important.
3116 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3117 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3119 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3121 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3122 prevent compiler warning
3124 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3126 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3127 moved to level 0 and declared as static. Also they are explicit
3128 placed in access bank. This was necessery because some times they
3129 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3130 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3131 optimizations. Currently only compare to unsigned char is implemented,
3132 * src/pic16/gen.c: added fReturnIdx array,
3133 * (struct resolvedIfx) is moved to gen.h and made public,
3134 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3135 * (aopForSym): added an optimization to directly store in stack of
3136 the operand of a SEND iCode,
3137 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3138 but as registers instead (AOP_REG) using the fReturnIdx array,
3139 * (pic16_freeAsmop): remove the freed register from the
3140 _G.sregsAlloc field,
3141 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3142 a compare of 'WREG',
3143 * (pic16_popGetTempRegCond): changed function prototype, now
3144 function takes also a bitVector argument v which holds the current
3145 set of registers that are allocated for stack access by aopForSym,
3146 registers allocated in aopForSym for accessing stack symbols are not
3147 any more part of the functions usedRegs field,
3148 * (genCall): some times aopOp is called for a stack variable to be
3149 send, aopForSym might perform the push, if this is true make sure
3150 that genCall doesn't push the variable twice by testing _G.resDirect,
3151 * (genFunction): changed testing for unspecified interrupt number
3152 from 256 to INTNO_UNSPEC,
3153 * modified selection scheme of frame pointer generation. Previously
3154 if function did use local registers a frame pointer was generated,
3155 now a frame pointer is generated only if function has arguments
3156 (that need PLUSW2 register access), or has stack arguments, or the
3157 compiler is not instructed to omit the frame pointer,
3158 * (genEndFunction): before restoring local registers that were saved
3159 in the function preamble, also restore the registers that *might*
3160 have been allocated for stack access,
3161 * (genRet): removed some old comments,
3162 * (genCmp, the active (RN's) version): added a call to the
3163 pic16_genCmp_special function to perform the compare with a more
3164 robust and optimized way,
3165 * (genInline): a feature has been added in inline code generation,
3166 which allows a wildcard variable substitution when writing inline
3167 assembly. Code is incomplete and experimental therefore undocumented,
3168 * (genCast): changed order of aopOp for result and right to allow
3169 aopForSym to directly load the result if possible,
3170 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3171 perform an optimized compare on some selected special occasions,
3172 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3173 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3174 generate an IVT any more,
3175 * src/pic16/main.c (pic16_optionsTable): added command line option
3177 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3178 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3180 * src/pic16/NOTES: Raphael Neider added in list of active developers
3181 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3182 jumptable_end to prevent bug #,
3183 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3184 inCond and outCond fields,
3185 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3186 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3187 turn off register spilling,
3188 * (packRegsForOneUse): synced with other ports' versions although it
3189 is not used currently,
3190 * (pic16_packRegisters): added an optimization while reading
3191 structure bitfields, some registers may be saved (malloc code is
3192 decreased by 80 bytes)
3194 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3196 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3197 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3198 this can be optimized more?
3200 2005-03-10 Raphael Neider <rneider AT web.de>
3202 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3203 genNearPointerGet): (hopefully) fixed access to bitfields via
3204 pointers (p->bitN = x; and x = p->bitN; failed)
3206 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3394 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3395 this might fix SIGSEGVs on MinGW...
3396 * src/SDCCopt.c (killDeadCode): restored original behaviour
3397 (volatile operands might get thrown away though)
3399 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3531 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3532 accessing SFRs. Updated all occurences of modification of stack or
3533 frame pointer in gen.c and pcode.c,

3838 Adding support for replacing ljmps with sjmps in jumptables
3839 generated for switch statements. For now you need to set the
3840 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3841 Now 4 algorithms for mcs51 jumptable generation are used:
3842 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3843 addresses loaded pc-relative for up to 112 cases and stack-pushing
3844 target addresses loaded with offset from dptr for up to 256 cases.

3874 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3876 * added libc directory. The current version of LibC contains string
3877 functions, ctype functions and macros and some functions of the
3878 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3879 be extensively tested in the future. Standard disclaimer here.
3880 Library is not automatically build yet. But one can build it by
3881 invoking 'make' inside the libc directory.

3891 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3892 * (pic16_storeForReturn): optimized return of 0,
3893 * (genCmp): experimental code for new genCmp which uses PIC18's
3894 special compare&skip instructions. Initial tests fail some times
3895 with variables grater than 1 byte in size, so new code is disabled,
3896 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3898 * (genCast): began a fix to optimize the casting of a bit to another
3899 bit, now assigning a bitfield to another bitfield will fail, sorry,
3900 * src/pic16/main.c: disabled the use of lr-support feature,
3901 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6922 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6924 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6925 loaded with the linker search paths (-L arguments) and the libraries
6926 to be linked with the current source (-l arguments). Changes
6927 currently will affect only the pic16 port.
6928 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6929 include path the port specific paths and port specific libraries,
6930 * gplink command now contains the $3 argument,
6931 * src/pic16/device.h,
6932 * src/pic16/device.c,: structure PIC_device is made public and
6933 renamed to PIC16_device, the same for variable Pics which is renamed

6948 Documenting changes from previous commits.
6949 * configure.in (version 1.56),
6950 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6951 when generating output files to configure the pic16 library,
6952 but now I've commented it out, since gputils aren't installed in the
6953 SF compile farm, so library won't compile
6955 * device/lib/Makefile.in (version 1.56): initially I've added in
6956 target 'all' the prerequestive 'model-pic16' so it compiled the
6957 pic16 library, but now I've commented it out for the same reasons
6959 * added targets 'model-pic16' and 'objects-pic16' to compile the
6961 * added target 'port-specific-objects-pic16' to handle the
6962 generated libraries and copy them into the build/ directory
6963 * added target 'clean-intermediate-pic16' to clean intermediate
6964 files into pic16 directory
6965 * in target 'installdirs' added line to create directory pic16 in
6966 the installation path
6968 * device/include/Makefile.in (version 1.11): in target 'install'
6969 added lines to copy all header files to installation path,
6970 * in target 'installdirs' added line create directory for pic16
6971 headers in the installation path

6987 option so that it actually works. Made it specific to the z80, since
6988 the gbz80 doesn't have these kinds of I/O ports.
6990 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7015 * src/pic16/device.c: stack is allocated via symbol and not
7016 via literal number. The symbol is placed in the corresponding
7017 position of the data ram
7018 * (pic16_dump_section): relocatable and absolute uninitialized
7019 data are now emitted in sorted order to reduce section naming,
7020 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7021 weren't marked as being in the access bank,
7023 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7025 Added portion of GNU PIC Library under the directory
7026 device/include/pic16 and device/lib/pic16. These files
7027 contain the declarations of SFRs for the PIC18Fxx2 devices.
7028 The directory is initialized via configure from toplevel.
7030 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7047 in simpler and even better code
7049 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7051 * src/SDCCicode.c (operandOperation): fixed bug #874819

7057 * doc/sdccman.lyx: Moved and added some sections, small changes
7058 all over. Telling LaTeX to be less strict with word spacing
7059 to better keep the right margin. Changed some notes about
7060 maintainance of the ports in section 3.2.1 - is it OK like this?
7062 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7099 UPPER for immediate operands,
7100 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7102 * src/pic16/peeph.def: all peepholes with movff are commented out,
7103 because there is a problem in the pcode peep optimizer,
7104 * src/pic16/ralloc.c: the register allocator can now reuse local
7105 function symbols for another function. This saves register usage.
7106 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7108 Added file src/pic16/NOTES with information about program writing on
7109 the current port version.

7168 * (pic14emitOverlay): modified to emit a commented overlay segment
7169 directive when no overlay data exist
7170 * (picglue): modified to emit uninitialized data segment
7171 according to udata_section_name

7214 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7216 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7217 (default behaviour).
7219 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7221 A python script to validate compiler diagnostic messages. It can be
7222 used to verify that sdcc complains about bad c source code and
7223 gives a good location of the error.
7224 * support/valdiag/Makefile,
7225 * support/valdiag/valdiag.py,
7226 * support/valdiag/tests/*

7243 Bug reported from Jesus Calvino-Fraga
7245 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7247 * sdcc.spec: updated
7248 * device/include/Makefile.in: don't install CVS directories
7249 * device/lib/Makefile.in: added removal of CVS directories after install
7250 * doc/Makefile: fixed install, added local_icons
7251 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7252 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7253 * src/ds390/gen.c (genRightShift): fixed bug #870788
7254 * src/SDCCast.c (decorateType): fixed bug #870781
7256 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7258 PIC16 port related changes:
7259 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7260 added variable stackPos,
7262 * gen.c: genCall, assignResultValue: added support for
7263 pushing/retrieving function parameters to/from stack,
7264 genFunction,genEndFunction: setup stack frame for the
7266 genAddrOf: will be changed according to bug 863624
7268 * added files genutils.c and genutils.h which contain gen*
7269 debugged and optimised functions extracted from gen.c
7271 * glue.c: added variable 'externs' which holds extern symbols,
7272 pic16emitRegularMap: is modified to properly handle relocatable
7273 symbols under the new scheme,
7274 pic16createInterruptVect: is modified
7275 pic16printPublics: is modified to emit 'global' assembler directives,
7276 added pic16_printExterns to print extern symbols,
7277 pic16glue: initializes stack/frame pointer in the beginning of
7278 the assembly output. Temporary hack, will be corrected later,
7279 because gplink yet does not support stack and SDCC does not
7280 yet support a type of crt0.o object to create the final binary.
7282 * Removed many lines that contain 8051 legacy code.
7283 * The code is finally placed under a 'code' directive.
7284 * Added port specific options.
7286 * _process_pragma: simplified since now we do not need *special*
7287 include file to define SFR registers. But a separate header
7288 will be needed. This will be developed later.
7289 * _pic16_parseOptions: added, parses port specific options:
7290 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7291 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7292 --preplace-udata-with=
7294 * _pic16_setDefaultOptions: modified to initialize section names,
7295 but hack is temporarly out of order since it needs improvement.
7296 * _pic16_genAssemblerPreamble: configuration words are emitted by
7297 their address instead of their name. This part is incomplete and
7298 supports only the 18Fxx2 devices. Other devices will emit an error
7299 during assembly since they do not contain the same set of config
7301 * _pic16_genIVT: is modified,
7303 * pcode.c: added definitions for some hardware registers that are needed
7305 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7306 All PCI entries are updated. Now LFSR is supported.
7307 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7308 * added pic16_newpCodeOpLit2 to support instructions with
7309 two literal arguments
7310 * pic16_pCode2str: corrected code that emits assembler instructions
7311 with two literal operands and those that have an access bit modifier
7312 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7313 this fixes a bug which caused some labels to be lost, when an
7314 assembler directive was added, i.e. banksel,
7315 * pic16_FixRegisterBanking: improved logic that causes the insertion
7317 * InlineFunction: functions that are called once, are not any more
7318 inlined. This can be a port option in the future,
7320 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7322 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7323 hold the corresponding uninitialized symbols,
7324 * pic16_allocProcessorRegister: registers have explicit marked the
7326 * pic16_allocInternalRegister: registers are explicit marked as
7328 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7329 processing list, so bit registers were lost,
7332 * ralloc.h: added field 'accessBank' and original symbol operand
7333 in register definition,
7334 * removed the field isMapped from register definition,
7336 ** Several functions have been removed from various sources:
7337 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7338 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7339 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7340 pic16_assignRelocatableRegisters
7342 ** others have been introduced:
7343 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7344 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7346 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7348 * support/scripts/inc2h.pl: changed definition of BIT_AT
7349 to emit 'sbit at' instead of 'bit at'. This was a request.
7351 PIC16 port related preliminary changes:
7352 * gen.c: prefixed function popRegFromString with
7353 pic16_ and all references to it corrected
7354 * pcode.c: all pic16_pc_* hardware registers prefixed
7355 with underscore (_),
7356 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7357 * ralloc.c: newReg(): when register is REG_SFR then
7358 set address to rIdx,
7359 pic16_allocProcessorRegister(): marks register wasUsed=0
7360 pic16_writeUsedRegs(): added a call to assign processor
7361 registers via pic16_assignFixedRegisters
7363 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7365 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7366 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7367 variables in unused register banks. Also the SSEG is placed
7368 wherever there is enough space for it, and IDATA can be anywhere
7369 in internal RAM. For now compile using -Wl-Y[stack_size].
7370 The mem file is different for this option as well, since it
7371 makes no sense of talking about DSEG lenght.
7373 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7375 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7376 in certain cases, e.g. when ROM assignment, patch provided
7377 from Albert den Haan.
7379 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7519 * src/mcs51/main.c: fixed bug #737001 for the mcs51. SDCC clears
7520 xdata and data memory on startup. Set the environment variable
7521 SDCC_NOGENRAMCLEAR to disable this.
7522 * src/mcs51/peephole.def,
7523 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7524 (allows non-interrupt and interrupt code to safely compete for a resource
7525 without the non-interrupt code having to disable interrupts)
7527 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7529 * src/SDCCicode.c (geniCodeAdd),
7530 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
7531 with valFromType if type might be a pointer and host is big endian).
7532 * src/SDCCast.c (decorateType): unary plus compatible with all arithmetic
7533 types, not just integer types.

7544 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7546 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
7547 Apparently this did not see much testing (endless loop)
7549 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7551 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
7553 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7622 it breaks with bitfields, extern declarations, and gcse analysis.
7623 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7624 could be assigned through a pointer, so don't complain.

8402 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8403 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8404 type for bits was changed. It resulted in bit variables becoming
8405 global, which is not permitted in PIC 14 assembly output.

8422 A few small changes that speed up the peephole optimizer.
8426 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8428 Try to make the peephole optimizer smarter by maintaining
8429 an association between the assembly source code and the
8430 iCodes that originated them. Put this information to use
8431 with a new peephole rule condition "notVolatile" so that
8432 the rules can be aggressive yet still safe.
8437 * src/mcs51/peeph.def
8439 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8443 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8444 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8445 if the left or right operand symbols have the accuse flag set.
8447 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8449 Changed the type of the result of the ! (NOT) operator to char;
8450 previously it returned the same type as the source. This allows
8451 us to eliminate all the genFloatNot functions (all of its target
8452 implementations were very buggy) since !float can use the same
8455 * src/SDCCicode.c (ast2iCode): ! returns char

8464 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8465 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8466 during interrupts. Ensure WSAVE is located at a shared bank address.
8467 2. Fixed page selection in some places
8468 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8469 the registers name strings.
8470 4. Fixed "signed / unsigned compare" compiler warnings.
8471 5. The PIC port manages its own allocation of the general purpose
8472 registers, but makes no attempt to reuse them. As a result when
8473 compiling it soon runs out of general purpose registers. Some
8474 additional code was added to the files pcode.c and device.c to walk
8475 through the function call tree and rename the registers so that they
8485 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8486 genPlus() & genMinus() when the result is the same as left or right

8492 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8494 Made bitfield a distinct type from bit so that bitfields
8495 convert as per ANSI C and bits retain their traditional
8496 boolean style behaviour. Implemented bitfield support in
8504 * src/ds390/gen.c: bit v bitfield split
8505 * src/z80/gen.c: New support for bitfields
8506 * support/regression/tests/bitfields.c: reenabled z80,
8509 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8511 Rules 246.x, 247.x relate to bitfields, the others speed up
8512 access to xdata mapped I/O devices.
8514 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x

8518 Cleaned up genPackBits and genUnpackBits and added two helper
8519 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8520 for literal assignments in genPackBits (thanks to Frieder for
8526 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8528 Fixed bug #748310 (pointer to function type mishandled when the
8529 function name is omitted). Also fixed a SIGSEGV when a function
8530 attribute (reentrant, etc) is used on a non-function or on a
8531 function but misplaced before the parameter list.

8560 Made the constant following the "interrupt" keyword optional. If
8561 omitted, the function will not automatically be given an entry
8562 in the interrupt vector table (similar to #pragma NOIV, but
8563 less syntacticly kludgy). The interrupt number is also now
8564 range checked. Also fixed a bug in the high order bit example

8585 unsigned, but are signed by default
8586 * src/SDCCval.c (constVal): rearranged
8587 * src/SDCCval.c (valMod): preliminary fix
8588 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9092 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9093 * src/SDCCmain.c: linkOptions is changed to set *,
9094 added if/endif conditional macros to remove options help
9095 messages from optionsTable when a port is not configured, added
9096 support for the PIc16 port in the ports table, when executing
9097 the compiler with no port specified on command line, a default
9098 port is selected with the new macro DEFAULT_PORT which is
9099 defined in port.h, in setDefaultOptions() linkOptions is removed
9100 from initialization assignment, since now it is a set,
9101 parseCmdLine uses setParseWithComma for linkOptions, in
9102 linkEdit() linkOptions are accessed with new function indexSet()
9103 which returns the i'th item of a set variable. See SDCCset.c, in
9104 linkEdit() when calling buildCmdLine(), added linkOptions as
9105 last argument. Now users can pass arguments to gplink via the
9106 -Wl option, main() uses pic16glue() to glue up pic16 programs

9118 * src/pic16/glue.c: commented out some error producing lines
9119 * src/pic16/main.c: __config directives are commented out to stop
9120 gpasm complaining and test the linkage with gplink, _linkCmd and
9121 _asmCmd changed to be more gplink and gpasm friendly
9122 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9123 produced an error when parsed, peep rule 12 is added to utilize
9124 movff, but it is commented out since the pCode does not support
9125 yet a command with 2 address arguments

10188 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10190 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10192 * in \sdcc\as\mcs51\ changed these files in order to create an
10193 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10194 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10195 following files to include the previous two files: aslink.dsp,
10196 Makefile.aslink, Makefile.bcc, and Makefile.in.
10198 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10199 .adb instead of .cdb
10201 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10203 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10204 value from option --iram-size.
10206 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10208 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10211 2002-09-18 <wiml AT hhhh.org>
10213 * SDCClrange.h: exposed setFromRange() and setToRange()
10214 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10215 packRegsForAccUse() (bug 542397)
10216 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10217 multiple times and emitting the fetch operations more than once
10218 added aopGetUsesAcc() function to allow binary operators to
10219 fetch their operands in the correct order; made genMinus() emit
10220 compact code for X = LITERAL - Y
10222 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10223 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10224 sprintf() in line 1267.
10226 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10227 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10230 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10231 Changes to aslink (All the changes are marked with 'JCF'):
10233 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10236 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10237 area BSEG. Also moves, if possible, the DATA area down into the internal
10238 ram so more space is available.
10240 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10243 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10244 not bytes. Function summary() which creates a memory usage summary
10245 file with extension .mem. Reports of overlaping stack and small stack
10246 size. If the space for the stack is less than 16 bytes aslink trows a
10249 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10250 the 8051. Option 'y' for memory summary output file.
10252 Changes to sdcc (All the changes are marked with 'JCF'):
10254 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10256 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10257 overlaying area for it (uses RegBankUsed[4]).
10259 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10260 bank zero as used by default. By default aslink locates the stack
10261 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10262 the creation of the .mem file. Delegates the allocation of data area
10263 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10264 the begining of the stack area to aslink.
10266 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10267 glue() in SDCCglue.c creates an area for it.
10269 2002-09-03 Borut Razem <borut.razem AT siol.net>
10270 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10271 sdcc/src/pic/glue.c:
10272 introduced atexit() handler for teporay files removal in case of
10273 errors, assertions, ...
10275 2002-08-29 Borut Razem <borut.razem AT siol.net>
10276 * sdcc/support/cpp2/auto-host_vc_in.h:
10277 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10278 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10279 Maybe there is a similar problem with BORLANDC? It should be checked!
10281 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10282 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10283 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10284 was not executed, and the compiler (cl) launched a warning:
10285 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10287 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10288 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10290 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10291 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10293 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10294 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10295 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10296 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10297 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10298 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10299 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10300 - added Release configuration in VS projects
10301 - review of compiler an linker options
10302 - VC .exe files are generated in bin_vc directory, not to interfere
10303 with binaries generated from other projects (cygwin, mingw, bcc ...)
10305 * sdcc/src/yacc.dsp: added
10307 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10308 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10309 and insert the version number definitions from .version
10311 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10313 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10314 added - genarate auto-host.h using auto-host_vc_in.h as template
10317 removed from CVS, generated automatically
10319 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10320 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10322 2002-08-11 Borut Razem <borut.razem AT siol.net>
10323 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10325 2002-08-10 Borut Razem <borut.razem AT siol.net>
10326 * src/SDCCmain.c (main):
10327 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10328 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10329 The consequence was that some temporary files were not removed.
10332 unification of code in functions tempfilename() and tempfile():
10333 function tempnam() is defined in Visual Studio 6.0 and .NET
10335 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10337 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10338 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10339 - removed compiler command line option /WX: Treats all warnings as errors
10340 - update a list of source files, included into the project
10342 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10343 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10344 changed project type to Generic Project so that can be correcly converted to VS.NET project
10346 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10348 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10350 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10352 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10353 added return 0 statements after assert() to make compiler happy
10355 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10356 added newline in the def file to keep MSC compiler satisfied
10358 * sdcc/src/z80/gen.c:
10359 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10360 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10361 - solved MSC error in function aopDump()
10363 * sdcc_vc.h: define PREFIX as "\\sdcc"
10365 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10366 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10368 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10369 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10370 - Rewrote the register banking algorithm.
10371 - Added pCode live-range analysis to registers (for now, only non-used and
10372 singly-used registers optimized away)
10374 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10376 * 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.
10378 2002-05-10 Scott Dattalo <scott AT dattalo.com>
