1183 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1185 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1186 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1188 One basic decision: e.g. src/clean.mk includes further files. In order
1189 to make this work there are two solutions:
1190 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1191 run configure on them. This way they can use
1192 'include $(srcdir)/port-clean.mk'
1193 - always include clean.mk by the Makefile at the same level. To avoid
1194 that `make clean` tries to include and build Makefile.dep the
1195 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1196 implemented, because now even `make uninstall` doesn't create
1197 Makefile.in. clean.mk could be eliminated by pasting it in
1200 * debugger/mcs51/Makefile.in: build own objects from library sources
1201 (SLIB, SDCC) in current directory
1203 * configure, configure.in: renamed --disable-device-lib-build in
1204 --disable-device-lib; added --enable-doc, the required tools are
1205 searched by configure; added result message; the toolchain for the
1206 belonging ports are now only built, if the port is enabled.
1208 * support/regression/*: all output is written in directory gen, because
1209 the fwk and ports directories don't livet in the build tree using vpath
1211 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1212 --disable-device-lib, added --enable-doc, added section VPATH
1214 * sim/ucsim/configure.in,
1215 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1216 z80 are enabled by default
1218 2006-04-24 Raphael Neider <rneider AT web.de>
1220 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1221 to config word, "pic14_"-prefixed some extern functions
1222 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1223 config word has been found
1224 * src/pic/device.h: added prototypes
1225 * src/pic/pcode.c: added "pic14_"-prefix where needed
1226 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1228 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1231 (pic14createInterruptVect): moved generating __config directives away
1232 (picglue): have __config directives emitted

1242 fixes #1469504 and #1474602,
1243 (pCodeRegOptimizeRegUsage): fixed typo in comment

1489 implemented patch 1120823 Thanks to Willy De la Court (normal
1490 interrupts need an interrupt number now if they are made critical),
1491 and enabled nesting of critical functions though not for gbz80
1492 (genCritical, genEndCritical): added functions
1493 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1494 * src/z80/mappings.i: added "ei" to all mappings

1506 the left operand is shorter than the result (c* = lit-c* + int),
1508 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1511 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1513 * src/.version: increased version number to 2.5.5
1514 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1515 linking is done manually in pic16 port's _linkEdit,
1516 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1517 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1518 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1519 allocate asmop as AOP_ACC,
1520 (aopForRemat): added parameter 'bool result' in function declaration,
1521 (pic16_aopGet): return AOP_ACC when accessing WREG,
1522 (pic16_popGetTempReg): minor modification,

1531 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1533 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1534 call to allocReg, not by manually allocating a new one,
1535 (pic16_assignRegisters): now before going through the register
1536 allocating functions mark all registers as free. This eliminates some
1537 side effects resulting from peephole parser done earlier in the backbone
1539 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1561 (aopForSym, aopOp): increment asmop.allocated if reused,
1562 (freeAsmop): decrement asmop.allocated and check for zero instead of

1597 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1598 which dumps before the function entry point a data byte which represents
1599 the number of the local variables used by the specified function, added
1600 'xinst' for initial support for Extended Instruction Support,
1601 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1602 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1603 port->fun_prefix anymore (may change later),
1604 (genFunction, genEndFunction): do not store/restore local registers for
1605 _main (this should take care the --main-return command line option in
1607 (genOr): removed some legacy pic-port instructions,
1608 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1609 performing operations with SFR's causes data to be written more than
1610 once to each SFR. Perhaps SFRs should be handled in special cases...
1611 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1613 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1614 into account for stack starting position,

1616 --extended or -y for Extended Instruction Support,
1617 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1618 (deassignLRs): *** perhaps the most important change, old 'for' code
1619 (commented out for reference), didn't account for some registers which
1620 were left marked 'not free' after a pointer operation. The change
1621 reduces register usage a lot in some cases
1623 2006-03-04 Borut Razem <borut.razem AT siol.net>

3888 on rIfx (genCmp was broken)
3890 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3892 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3893 * src/z80/main.c (_keywords[]),
3894 * src/SDCCglobal.h (struct options),
3896 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3897 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3898 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3899 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3900 always available in leading double underscore form. The C99 support is
3901 mostly missing, but it's a start.
3902 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3903 reserved identifier "__data".
3905 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3951 2005-03-20 Borut Razem <borut.razem AT siol.net>
3953 * support/scripts/inc2h.pl: WIN32 port

3981 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3983 * device/lib/printf_large.c: removed inline assembly for portability and
3984 readability. Use printf_fast if speed or size are more important.
3985 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3986 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3988 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3990 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3991 prevent compiler warning
3993 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3995 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3996 moved to level 0 and declared as static. Also they are explicit
3997 placed in access bank. This was necessery because some times they
3998 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3999 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4000 optimizations. Currently only compare to unsigned char is implemented,
4001 * src/pic16/gen.c: added fReturnIdx array,
4002 * (struct resolvedIfx) is moved to gen.h and made public,
4003 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4004 * (aopForSym): added an optimization to directly store in stack of
4005 the operand of a SEND iCode,
4006 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4007 but as registers instead (AOP_REG) using the fReturnIdx array,
4008 * (pic16_freeAsmop): remove the freed register from the
4009 _G.sregsAlloc field,
4010 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4011 a compare of 'WREG',
4012 * (pic16_popGetTempRegCond): changed function prototype, now
4013 function takes also a bitVector argument v which holds the current
4014 set of registers that are allocated for stack access by aopForSym,
4015 registers allocated in aopForSym for accessing stack symbols are not
4016 any more part of the functions usedRegs field,
4017 * (genCall): some times aopOp is called for a stack variable to be
4018 send, aopForSym might perform the push, if this is true make sure
4019 that genCall doesn't push the variable twice by testing _G.resDirect,
4020 * (genFunction): changed testing for unspecified interrupt number
4021 from 256 to INTNO_UNSPEC,
4022 * modified selection scheme of frame pointer generation. Previously
4023 if function did use local registers a frame pointer was generated,
4024 now a frame pointer is generated only if function has arguments
4025 (that need PLUSW2 register access), or has stack arguments, or the
4026 compiler is not instructed to omit the frame pointer,
4027 * (genEndFunction): before restoring local registers that were saved
4028 in the function preamble, also restore the registers that *might*
4029 have been allocated for stack access,
4030 * (genRet): removed some old comments,
4031 * (genCmp, the active (RN's) version): added a call to the
4032 pic16_genCmp_special function to perform the compare with a more
4033 robust and optimized way,
4034 * (genInline): a feature has been added in inline code generation,
4035 which allows a wildcard variable substitution when writing inline
4036 assembly. Code is incomplete and experimental therefore undocumented,
4037 * (genCast): changed order of aopOp for result and right to allow
4038 aopForSym to directly load the result if possible,
4039 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4040 perform an optimized compare on some selected special occasions,
4041 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4042 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4043 generate an IVT any more,
4044 * src/pic16/main.c (pic16_optionsTable): added command line option
4046 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4047 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4049 * src/pic16/NOTES: Raphael Neider added in list of active developers
4050 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4051 jumptable_end to prevent bug #,
4052 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4053 inCond and outCond fields,
4054 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4055 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4056 turn off register spilling,
4057 * (packRegsForOneUse): synced with other ports' versions although it
4058 is not used currently,
4059 * (pic16_packRegisters): added an optimization while reading
4060 structure bitfields, some registers may be saved (malloc code is
4061 decreased by 80 bytes)
4063 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4065 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4066 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4067 this can be optimized more?
4069 2005-03-10 Raphael Neider <rneider AT web.de>
4071 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4072 genNearPointerGet): (hopefully) fixed access to bitfields via
4073 pointers (p->bitN = x; and x = p->bitN; failed)
4075 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4261 of (byte sized) temporaries (assign them to WREG for now)
4262 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4263 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4264 this might fix SIGSEGVs on MinGW...
4265 * src/SDCCopt.c (killDeadCode): restored original behaviour
4266 (volatile operands might get thrown away though)
4268 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4270 * src/pic16/gen.c: fixed bug #1106975,

4740 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4741 to call when a stack overflow occurs,
4742 * (malloc.h): added CVS Id tag,
4743 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4745 * added libc directory. The current version of LibC contains string
4746 functions, ctype functions and macros and some functions of the
4747 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4748 be extensively tested in the future. Standard disclaimer here.
4749 Library is not automatically build yet. But one can build it by
4750 invoking 'make' inside the libc directory.
4751 * added ADC library under libio. Preliminary version yet.
4753 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4754 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4755 aopForRemat() now and not by pic16_aopOp(),
4756 * (pic16_popGetTempReg): removed warning messgae when allocating
4757 temporary registers, its a buggy feature and will be removed,
4758 * (pic16_popGet): set register instance field in AOP_CRY,
4759 * (pic16_outBitC): fixed for results in size greater than 1,
4760 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4761 * (pic16_storeForReturn): optimized return of 0,
4762 * (genCmp): experimental code for new genCmp which uses PIC18's
4763 special compare&skip instructions. Initial tests fail some times
4764 with variables grater than 1 byte in size, so new code is disabled,
4765 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4767 * (genCast): began a fix to optimize the casting of a bit to another
4768 bit, now assigning a bitfield to another bitfield will fail, sorry,
4769 * src/pic16/main.c: disabled the use of lr-support feature,
4770 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4771 * added some function prototypes, added function _debugf prototype,
4772 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4773 bits with offset (case PO_GPR_BIT),
4774 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4776 * (isBankInstruction): modified to return 0 for no banking instruction,
4777 and 1 for banking instruction,
4778 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4779 caused stop processing pCodes after a inline assembly block,
4780 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4781 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4782 registers when it shouldn't,
4783 * src/pic16/ralloc.c (allocReg): add preliminary support for
4784 supporting a limited set of temporary registers,
4786 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4788 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4789 genDataPointerSet): ensure assignments always copy in MSB to LSB
4791 (loadRegFromAop): recognize CLRH optimization,
4792 (genFunction): optimize RECEIVE iCodes in reentrant functions
4794 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4796 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4797 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4799 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
4800 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
4801 contiguous with data
4803 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4805 * device/lib/_gptrget.c (_gptrget),
4806 * device/lib/_gptrgetc.c (_gptrgetc),
4807 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4808 instead of sjmp to ret
4809 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4810 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4812 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7791 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7793 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7794 loaded with the linker search paths (-L arguments) and the libraries
7795 to be linked with the current source (-l arguments). Changes
7796 currently will affect only the pic16 port.
7797 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7798 include path the port specific paths and port specific libraries,
7799 * gplink command now contains the $3 argument,
7800 * src/pic16/device.h,
7801 * src/pic16/device.c,: structure PIC_device is made public and
7802 renamed to PIC16_device, the same for variable Pics which is renamed

7817 Documenting changes from previous commits.
7818 * configure.in (version 1.56),
7819 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7820 when generating output files to configure the pic16 library,
7821 but now I've commented it out, since gputils aren't installed in the
7822 SF compile farm, so library won't compile
7824 * device/lib/Makefile.in (version 1.56): initially I've added in
7825 target 'all' the prerequestive 'model-pic16' so it compiled the
7826 pic16 library, but now I've commented it out for the same reasons
7828 * added targets 'model-pic16' and 'objects-pic16' to compile the
7830 * added target 'port-specific-objects-pic16' to handle the
7831 generated libraries and copy them into the build/ directory
7832 * added target 'clean-intermediate-pic16' to clean intermediate
7833 files into pic16 directory
7834 * in target 'installdirs' added line to create directory pic16 in
7835 the installation path

7885 via literal number. The symbol is placed in the corresponding
7886 position of the data ram
7887 * (pic16_dump_section): relocatable and absolute uninitialized
7888 data are now emitted in sorted order to reduce section naming,
7889 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7890 weren't marked as being in the access bank,
7892 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7894 Added portion of GNU PIC Library under the directory
7895 device/include/pic16 and device/lib/pic16. These files
7896 contain the declarations of SFRs for the PIC18Fxx2 devices.

7927 all over. Telling LaTeX to be less strict with word spacing
7928 to better keep the right margin. Changed some notes about
7929 maintainance of the ports in section 3.2.1 - is it OK like this?
7931 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7971 * src/pic16/peeph.def: all peepholes with movff are commented out,
7972 because there is a problem in the pcode peep optimizer,
7973 * src/pic16/ralloc.c: the register allocator can now reuse local

8010 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8013 * src/z80/main.c: added missed needLinkerScript flags (more than
8014 one port structure defined in these file)
8015 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8066 include information about variables allocated to the overlay
8069 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8071 * as/mcs51/lkmain.c: Help about -Y option

8083 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8085 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8086 (default behaviour).
8088 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8090 A python script to validate compiler diagnostic messages. It can be
8091 used to verify that sdcc complains about bad c source code and
8092 gives a good location of the error.
8093 * support/valdiag/Makefile,
8094 * support/valdiag/valdiag.py,
8095 * support/valdiag/tests/*
8097 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8110 * src/common.h: added ifndef/define/endif macros
8111 around the header file.
8112 Bug reported from Jesus Calvino-Fraga
8114 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8116 * sdcc.spec: updated
8117 * device/include/Makefile.in: don't install CVS directories
8118 * device/lib/Makefile.in: added removal of CVS directories after install
8119 * doc/Makefile: fixed install, added local_icons
8120 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8121 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8122 * src/ds390/gen.c (genRightShift): fixed bug #870788
8123 * src/SDCCast.c (decorateType): fixed bug #870781
8125 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8127 PIC16 port related changes:
8128 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8129 added variable stackPos,
8131 * gen.c: genCall, assignResultValue: added support for
8132 pushing/retrieving function parameters to/from stack,
8133 genFunction,genEndFunction: setup stack frame for the
8135 genAddrOf: will be changed according to bug 863624
8137 * added files genutils.c and genutils.h which contain gen*
8138 debugged and optimised functions extracted from gen.c
8140 * glue.c: added variable 'externs' which holds extern symbols,
8141 pic16emitRegularMap: is modified to properly handle relocatable
8142 symbols under the new scheme,
8143 pic16createInterruptVect: is modified
8144 pic16printPublics: is modified to emit 'global' assembler directives,
8145 added pic16_printExterns to print extern symbols,
8146 pic16glue: initializes stack/frame pointer in the beginning of
8147 the assembly output. Temporary hack, will be corrected later,
8148 because gplink yet does not support stack and SDCC does not
8149 yet support a type of crt0.o object to create the final binary.
8151 * Removed many lines that contain 8051 legacy code.
8152 * The code is finally placed under a 'code' directive.
8153 * Added port specific options.
8155 * _process_pragma: simplified since now we do not need *special*
8156 include file to define SFR registers. But a separate header
8157 will be needed. This will be developed later.
8158 * _pic16_parseOptions: added, parses port specific options:
8159 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8160 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8161 --preplace-udata-with=
8163 * _pic16_setDefaultOptions: modified to initialize section names,
8164 but hack is temporarly out of order since it needs improvement.
8165 * _pic16_genAssemblerPreamble: configuration words are emitted by
8166 their address instead of their name. This part is incomplete and
8167 supports only the 18Fxx2 devices. Other devices will emit an error
8168 during assembly since they do not contain the same set of config
8170 * _pic16_genIVT: is modified,
8172 * pcode.c: added definitions for some hardware registers that are needed
8174 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8175 All PCI entries are updated. Now LFSR is supported.
8176 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8177 * added pic16_newpCodeOpLit2 to support instructions with
8178 two literal arguments
8179 * pic16_pCode2str: corrected code that emits assembler instructions
8180 with two literal operands and those that have an access bit modifier
8181 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8182 this fixes a bug which caused some labels to be lost, when an
8183 assembler directive was added, i.e. banksel,
8184 * pic16_FixRegisterBanking: improved logic that causes the insertion
8186 * InlineFunction: functions that are called once, are not any more
8187 inlined. This can be a port option in the future,
8189 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8191 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8192 hold the corresponding uninitialized symbols,
8193 * pic16_allocProcessorRegister: registers have explicit marked the
8195 * pic16_allocInternalRegister: registers are explicit marked as
8197 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8198 processing list, so bit registers were lost,
8201 * ralloc.h: added field 'accessBank' and original symbol operand
8202 in register definition,
8203 * removed the field isMapped from register definition,
8205 ** Several functions have been removed from various sources:
8206 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8207 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8208 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8209 pic16_assignRelocatableRegisters
8211 ** others have been introduced:
8212 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8213 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8215 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8217 * support/scripts/inc2h.pl: changed definition of BIT_AT
8218 to emit 'sbit at' instead of 'bit at'. This was a request.
8220 PIC16 port related preliminary changes:
8221 * gen.c: prefixed function popRegFromString with
8222 pic16_ and all references to it corrected
8223 * pcode.c: all pic16_pc_* hardware registers prefixed
8224 with underscore (_),
8225 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8226 * ralloc.c: newReg(): when register is REG_SFR then
8227 set address to rIdx,
8228 pic16_allocProcessorRegister(): marks register wasUsed=0
8229 pic16_writeUsedRegs(): added a call to assign processor
8230 registers via pic16_assignFixedRegisters
8232 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8234 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8235 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8236 variables in unused register banks. Also the SSEG is placed
8237 wherever there is enough space for it, and IDATA can be anywhere
8238 in internal RAM. For now compile using -Wl-Y[stack_size].
8239 The mem file is different for this option as well, since it
8240 makes no sense of talking about DSEG lenght.
8242 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8244 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8245 in certain cases, e.g. when ROM assignment, patch provided
8246 from Albert den Haan.
8248 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9255 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9256 If they pop r0/r1 they must be called in the opposite order than aopOp().
9257 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9258 (resp. --stack-auto), prepared for --xstack

9269 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9271 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9272 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9273 type for bits was changed. It resulted in bit variables becoming

9289 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9291 A few small changes that speed up the peephole optimizer.
9295 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9297 Try to make the peephole optimizer smarter by maintaining
9298 an association between the assembly source code and the
9299 iCodes that originated them. Put this information to use
9300 with a new peephole rule condition "notVolatile" so that
9301 the rules can be aggressive yet still safe.
9306 * src/mcs51/peeph.def
9308 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9312 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9313 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9314 if the left or right operand symbols have the accuse flag set.
9316 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9318 Changed the type of the result of the ! (NOT) operator to char;
9319 previously it returned the same type as the source. This allows
9320 us to eliminate all the genFloatNot functions (all of its target
9321 implementations were very buggy) since !float can use the same
9324 * src/SDCCicode.c (ast2iCode): ! returns char
9325 * src/mcs51/gen.c (genNot, genNotFloat),
9326 * src/ds390/gen.c (genNot, genNotFloat),
9327 * src/z80/gen.c (genNot, genNotFloat),
9328 * src/pic/gen.c (genNot, genNotFloat),

9333 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9334 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9335 during interrupts. Ensure WSAVE is located at a shared bank address.
9336 2. Fixed page selection in some places
9337 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9338 the registers name strings.
9339 4. Fixed "signed / unsigned compare" compiler warnings.
9340 5. The PIC port manages its own allocation of the general purpose
9341 registers, but makes no attempt to reuse them. As a result when
9342 compiling it soon runs out of general purpose registers. Some
9343 additional code was added to the files pcode.c and device.c to walk
9344 through the function call tree and rename the registers so that they
9354 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9361 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9363 Made bitfield a distinct type from bit so that bitfields
9364 convert as per ANSI C and bits retain their traditional
9365 boolean style behaviour. Implemented bitfield support in
9373 * src/ds390/gen.c: bit v bitfield split
9374 * src/z80/gen.c: New support for bitfields
9375 * support/regression/tests/bitfields.c: reenabled z80,
9378 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9380 Rules 246.x, 247.x relate to bitfields, the others speed up
9381 access to xdata mapped I/O devices.
9383 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9385 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9387 Cleaned up genPackBits and genUnpackBits and added two helper
9388 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9389 for literal assignments in genPackBits (thanks to Frieder for
9395 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9397 Fixed bug #748310 (pointer to function type mishandled when the
9398 function name is omitted). Also fixed a SIGSEGV when a function
9399 attribute (reentrant, etc) is used on a non-function or on a
9400 function but misplaced before the parameter list.
9402 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9404 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9427 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9429 Made the constant following the "interrupt" keyword optional. If
9430 omitted, the function will not automatically be given an entry
9431 in the interrupt vector table (similar to #pragma NOIV, but
9432 less syntacticly kludgy). The interrupt number is also now
9433 range checked. Also fixed a bug in the high order bit example

9454 unsigned, but are signed by default
9455 * src/SDCCval.c (constVal): rearranged
9456 * src/SDCCval.c (valMod): preliminary fix
9457 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9962 * src/SDCCmain.c: linkOptions is changed to set *,
9963 added if/endif conditional macros to remove options help
9964 messages from optionsTable when a port is not configured, added
9965 support for the PIc16 port in the ports table, when executing
9966 the compiler with no port specified on command line, a default
9967 port is selected with the new macro DEFAULT_PORT which is
9968 defined in port.h, in setDefaultOptions() linkOptions is removed
9969 from initialization assignment, since now it is a set,
9970 parseCmdLine uses setParseWithComma for linkOptions, in
9971 linkEdit() linkOptions are accessed with new function indexSet()
9972 which returns the i'th item of a set variable. See SDCCset.c, in
9973 linkEdit() when calling buildCmdLine(), added linkOptions as
9974 last argument. Now users can pass arguments to gplink via the
9975 -Wl option, main() uses pic16glue() to glue up pic16 programs

9987 * src/pic16/glue.c: commented out some error producing lines
9988 * src/pic16/main.c: __config directives are commented out to stop
9989 gpasm complaining and test the linkage with gplink, _linkCmd and
9990 _asmCmd changed to be more gplink and gpasm friendly
9991 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9992 produced an error when parsed, peep rule 12 is added to utilize
9993 movff, but it is commented out since the pCode does not support
9994 yet a command with 2 address arguments
9996 2003-05-18 <johan AT balder>
9998 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11059 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11061 * in /sdcc/as/mcs51/ changed these files in order to create an
11062 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11063 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11064 following files to include the previous two files: aslink.dsp,
11065 Makefile.aslink, Makefile.bcc, and Makefile.in.
11067 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11068 .adb instead of .cdb
11070 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11072 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11073 value from option --iram-size.
11075 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11077 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11080 2002-09-18 <wiml AT hhhh.org>
11082 * SDCClrange.h: exposed setFromRange() and setToRange()
11083 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11084 packRegsForAccUse() (bug 542397)
11085 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11086 multiple times and emitting the fetch operations more than once
11087 added aopGetUsesAcc() function to allow binary operators to
11088 fetch their operands in the correct order; made genMinus() emit
11089 compact code for X = LITERAL - Y
11091 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11092 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11093 sprintf() in line 1267.
11095 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11096 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11099 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11100 Changes to aslink (All the changes are marked with 'JCF'):
11102 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11105 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11106 area BSEG. Also moves, if possible, the DATA area down into the internal
11107 ram so more space is available.
11109 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11112 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11113 not bytes. Function summary() which creates a memory usage summary
11114 file with extension .mem. Reports of overlaping stack and small stack
11115 size. If the space for the stack is less than 16 bytes aslink trows a
11118 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11119 the 8051. Option 'y' for memory summary output file.
11121 Changes to sdcc (All the changes are marked with 'JCF'):
11123 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11125 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11126 overlaying area for it (uses RegBankUsed[4]).
11128 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11129 bank zero as used by default. By default aslink locates the stack
11130 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11131 the creation of the .mem file. Delegates the allocation of data area
11132 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11133 the begining of the stack area to aslink.
11135 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11136 glue() in SDCCglue.c creates an area for it.
11138 2002-09-03 Borut Razem <borut.razem AT siol.net>
11139 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11140 sdcc/src/pic/glue.c:
11141 introduced atexit() handler for teporay files removal in case of
11142 errors, assertions, ...
11144 2002-08-29 Borut Razem <borut.razem AT siol.net>
11145 * sdcc/support/cpp2/auto-host_vc_in.h:
11146 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11147 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11148 Maybe there is a similar problem with BORLANDC? It should be checked!
11150 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11151 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11152 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11153 was not executed, and the compiler (cl) launched a warning:
11154 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11156 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11157 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11169 - added Release configuration in VS projects
11170 - review of compiler an linker options
11171 - VC .exe files are generated in bin_vc directory, not to interfere
11172 with binaries generated from other projects (cygwin, mingw, bcc ...)
11174 * sdcc/src/yacc.dsp: added
11176 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11177 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11178 and insert the version number definitions from .version
11180 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11182 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

11189 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11191 2002-08-11 Borut Razem <borut.razem AT siol.net>
11192 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11194 2002-08-10 Borut Razem <borut.razem AT siol.net>
11195 * src/SDCCmain.c (main):
11196 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11197 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11198 The consequence was that some temporary files were not removed.
11201 unification of code in functions tempfilename() and tempfile():
11202 function tempnam() is defined in Visual Studio 6.0 and .NET
11204 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11206 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11207 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11208 - removed compiler command line option /WX: Treats all warnings as errors
11209 - update a list of source files, included into the project
11211 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11212 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11213 changed project type to Generic Project so that can be correcly converted to VS.NET project
11215 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11217 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

11221 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11222 added return 0 statements after assert() to make compiler happy
11224 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11225 added newline in the def file to keep MSC compiler satisfied
11227 * sdcc/src/z80/gen.c:
11228 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11229 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11230 - solved MSC error in function aopDump()
11232 * sdcc_vc.h: define PREFIX as "\\sdcc"
11234 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11409 * sdcc/src/SDCCloop.c:
11410 Previous fix was not good. basic blocks that have "break" or "return" are
11411 not really partof a loop , but live ranges used in these blocks should
