1226 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1228 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1229 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1231 One basic decision: e.g. src/clean.mk includes further files. In order
1232 to make this work there are two solutions:
1233 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1234 run configure on them. This way they can use
1235 'include $(srcdir)/port-clean.mk'
1236 - always include clean.mk by the Makefile at the same level. To avoid
1237 that `make clean` tries to include and build Makefile.dep the
1238 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1239 implemented, because now even `make uninstall` doesn't create
1240 Makefile.in. clean.mk could be eliminated by pasting it in
1243 * debugger/mcs51/Makefile.in: build own objects from library sources
1244 (SLIB, SDCC) in current directory
1246 * configure, configure.in: renamed --disable-device-lib-build in
1247 --disable-device-lib; added --enable-doc, the required tools are
1248 searched by configure; added result message; the toolchain for the
1249 belonging ports are now only built, if the port is enabled.
1251 * support/regression/*: all output is written in directory gen, because
1252 the fwk and ports directories don't livet in the build tree using vpath
1254 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1255 --disable-device-lib, added --enable-doc, added section VPATH
1257 * sim/ucsim/configure.in,
1258 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1259 z80 are enabled by default
1261 2006-04-24 Raphael Neider <rneider AT web.de>
1263 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1264 to config word, "pic14_"-prefixed some extern functions
1265 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1266 config word has been found
1267 * src/pic/device.h: added prototypes
1268 * src/pic/pcode.c: added "pic14_"-prefix where needed
1269 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1271 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1273 (pic14emitRegularMap): ignore config words,
1274 (pic14createInterruptVect): moved generating __config directives away

1285 fixes #1469504 and #1474602,
1286 (pCodeRegOptimizeRegUsage): fixed typo in comment

1290 * device/examples/main8051.c: deleted - it was removed from CVS
1291 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1292 after the transition to Subversion

1294 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1532 implemented patch 1120823 Thanks to Willy De la Court (normal
1533 interrupts need an interrupt number now if they are made critical),
1534 and enabled nesting of critical functions though not for gbz80
1535 (genCritical, genEndCritical): added functions
1536 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1537 * src/z80/mappings.i: added "ei" to all mappings

1549 the left operand is shorter than the result (c* = lit-c* + int),
1551 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1554 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1556 * src/.version: increased version number to 2.5.5
1557 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1558 linking is done manually in pic16 port's _linkEdit,
1559 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1560 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1561 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1562 allocate asmop as AOP_ACC,
1563 (aopForRemat): added parameter 'bool result' in function declaration,
1564 (pic16_aopGet): return AOP_ACC when accessing WREG,
1565 (pic16_popGetTempReg): minor modification,

1576 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1577 call to allocReg, not by manually allocating a new one,
1578 (pic16_assignRegisters): now before going through the register
1579 allocating functions mark all registers as free. This eliminates some
1580 side effects resulting from peephole parser done earlier in the backbone
1582 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1640 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1641 which dumps before the function entry point a data byte which represents
1642 the number of the local variables used by the specified function, added
1643 'xinst' for initial support for Extended Instruction Support,
1644 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1645 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1646 port->fun_prefix anymore (may change later),
1647 (genFunction, genEndFunction): do not store/restore local registers for
1648 _main (this should take care the --main-return command line option in
1650 (genOr): removed some legacy pic-port instructions,
1651 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1652 performing operations with SFR's causes data to be written more than
1653 once to each SFR. Perhaps SFRs should be handled in special cases...
1654 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1656 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1657 into account for stack starting position,

1659 --extended or -y for Extended Instruction Support,
1660 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1661 (deassignLRs): *** perhaps the most important change, old 'for' code
1662 (commented out for reference), didn't account for some registers which
1663 were left marked 'not free' after a pointer operation. The change
1664 reduces register usage a lot in some cases
1666 2006-03-04 Borut Razem <borut.razem AT siol.net>

3931 on rIfx (genCmp was broken)
3933 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3935 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3936 * src/z80/main.c (_keywords[]),
3937 * src/SDCCglobal.h (struct options),
3939 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3940 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3941 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3942 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3943 always available in leading double underscore form. The C99 support is
3944 mostly missing, but it's a start.
3945 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3946 reserved identifier "__data".
3948 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3994 2005-03-20 Borut Razem <borut.razem AT siol.net>
3996 * support/scripts/inc2h.pl: WIN32 port

4024 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4026 * device/lib/printf_large.c: removed inline assembly for portability and
4027 readability. Use printf_fast if speed or size are more important.
4028 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4029 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4031 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4033 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4034 prevent compiler warning
4036 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4038 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4039 moved to level 0 and declared as static. Also they are explicit
4040 placed in access bank. This was necessery because some times they
4041 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4042 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4043 optimizations. Currently only compare to unsigned char is implemented,
4044 * src/pic16/gen.c: added fReturnIdx array,
4045 * (struct resolvedIfx) is moved to gen.h and made public,
4046 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4047 * (aopForSym): added an optimization to directly store in stack of
4048 the operand of a SEND iCode,
4049 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4050 but as registers instead (AOP_REG) using the fReturnIdx array,
4051 * (pic16_freeAsmop): remove the freed register from the
4052 _G.sregsAlloc field,
4053 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4054 a compare of 'WREG',
4055 * (pic16_popGetTempRegCond): changed function prototype, now
4056 function takes also a bitVector argument v which holds the current
4057 set of registers that are allocated for stack access by aopForSym,
4058 registers allocated in aopForSym for accessing stack symbols are not
4059 any more part of the functions usedRegs field,
4060 * (genCall): some times aopOp is called for a stack variable to be
4061 send, aopForSym might perform the push, if this is true make sure
4062 that genCall doesn't push the variable twice by testing _G.resDirect,
4063 * (genFunction): changed testing for unspecified interrupt number
4064 from 256 to INTNO_UNSPEC,
4065 * modified selection scheme of frame pointer generation. Previously
4066 if function did use local registers a frame pointer was generated,
4067 now a frame pointer is generated only if function has arguments
4068 (that need PLUSW2 register access), or has stack arguments, or the
4069 compiler is not instructed to omit the frame pointer,
4070 * (genEndFunction): before restoring local registers that were saved
4071 in the function preamble, also restore the registers that *might*
4072 have been allocated for stack access,
4073 * (genRet): removed some old comments,
4074 * (genCmp, the active (RN's) version): added a call to the
4075 pic16_genCmp_special function to perform the compare with a more
4076 robust and optimized way,
4077 * (genInline): a feature has been added in inline code generation,
4078 which allows a wildcard variable substitution when writing inline
4079 assembly. Code is incomplete and experimental therefore undocumented,
4080 * (genCast): changed order of aopOp for result and right to allow
4081 aopForSym to directly load the result if possible,
4082 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4083 perform an optimized compare on some selected special occasions,
4084 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4085 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4086 generate an IVT any more,
4087 * src/pic16/main.c (pic16_optionsTable): added command line option
4089 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4090 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4092 * src/pic16/NOTES: Raphael Neider added in list of active developers
4093 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4094 jumptable_end to prevent bug #,
4095 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4096 inCond and outCond fields,
4097 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4098 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4099 turn off register spilling,
4100 * (packRegsForOneUse): synced with other ports' versions although it
4101 is not used currently,
4102 * (pic16_packRegisters): added an optimization while reading
4103 structure bitfields, some registers may be saved (malloc code is
4104 decreased by 80 bytes)
4106 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4108 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4109 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4110 this can be optimized more?
4112 2005-03-10 Raphael Neider <rneider AT web.de>
4114 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4115 genNearPointerGet): (hopefully) fixed access to bitfields via
4116 pointers (p->bitN = x; and x = p->bitN; failed)
4118 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4295 * src/pic16/main.c (_process_pragma): fixed another malloc bug
4296 (sizeof(sectNames) changed to sizeof(sectName))
4297 Both patches fix segfaults under MinGW.

4303 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
4304 of (byte sized) temporaries (assign them to WREG for now)
4305 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4306 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4307 this might fix SIGSEGVs on MinGW...
4308 * src/SDCCopt.c (killDeadCode): restored original behaviour
4309 (volatile operands might get thrown away though)
4311 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4313 * src/pic16/gen.c: fixed bug #1106975,

4750 Adding support for replacing ljmps with sjmps in jumptables
4751 generated for switch statements. For now you need to set the
4752 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4753 Now 4 algorithms for mcs51 jumptable generation are used:
4754 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4780 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4782 Large cummulative patch for pic16 port.
4783 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4784 to call when a stack overflow occurs,
4785 * (malloc.h): added CVS Id tag,
4786 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4788 * added libc directory. The current version of LibC contains string
4789 functions, ctype functions and macros and some functions of the
4790 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4791 be extensively tested in the future. Standard disclaimer here.
4792 Library is not automatically build yet. But one can build it by
4793 invoking 'make' inside the libc directory.
4794 * added ADC library under libio. Preliminary version yet.
4796 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4797 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4798 aopForRemat() now and not by pic16_aopOp(),

4803 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4804 * (pic16_storeForReturn): optimized return of 0,
4805 * (genCmp): experimental code for new genCmp which uses PIC18's
4806 special compare&skip instructions. Initial tests fail some times
4807 with variables grater than 1 byte in size, so new code is disabled,
4808 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4810 * (genCast): began a fix to optimize the casting of a bit to another
4811 bit, now assigning a bitfield to another bitfield will fail, sorry,
4812 * src/pic16/main.c: disabled the use of lr-support feature,
4813 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4814 * added some function prototypes, added function _debugf prototype,
4815 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4816 bits with offset (case PO_GPR_BIT),
4817 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4819 * (isBankInstruction): modified to return 0 for no banking instruction,
4820 and 1 for banking instruction,
4821 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4822 caused stop processing pCodes after a inline assembly block,
4823 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4824 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4825 registers when it shouldn't,
4826 * src/pic16/ralloc.c (allocReg): add preliminary support for
4827 supporting a limited set of temporary registers,
4829 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4831 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4832 genDataPointerSet): ensure assignments always copy in MSB to LSB
4834 (loadRegFromAop): recognize CLRH optimization,
4835 (genFunction): optimize RECEIVE iCodes in reentrant functions
4837 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4839 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4840 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4842 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

7837 loaded with the linker search paths (-L arguments) and the libraries
7838 to be linked with the current source (-l arguments). Changes
7839 currently will affect only the pic16 port.
7840 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7841 include path the port specific paths and port specific libraries,
7842 * gplink command now contains the $3 argument,

7860 Documenting changes from previous commits.
7861 * configure.in (version 1.56),
7862 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7863 when generating output files to configure the pic16 library,
7864 but now I've commented it out, since gputils aren't installed in the
7865 SF compile farm, so library won't compile
7867 * device/lib/Makefile.in (version 1.56): initially I've added in
7868 target 'all' the prerequestive 'model-pic16' so it compiled the
7869 pic16 library, but now I've commented it out for the same reasons
7871 * added targets 'model-pic16' and 'objects-pic16' to compile the
7873 * added target 'port-specific-objects-pic16' to handle the
7874 generated libraries and copy them into the build/ directory
7875 * added target 'clean-intermediate-pic16' to clean intermediate
7876 files into pic16 directory
7877 * in target 'installdirs' added line to create directory pic16 in
7878 the installation path
7880 * device/include/Makefile.in (version 1.11): in target 'install'
7881 added lines to copy all header files to installation path,
7882 * in target 'installdirs' added line create directory for pic16
7883 headers in the installation path
7885 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7898 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7899 option so that it actually works. Made it specific to the z80, since
7900 the gbz80 doesn't have these kinds of I/O ports.
7902 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7904 * device/include/z180.h,

7910 * device/lib/_strcmp.c,
7911 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7912 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7913 portmode; added deprecation warning for bank= and protmode= forms.
7914 Also, guard against buffer overflow.
7915 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7917 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7919 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7920 changed interrupt vector table generation to only emit declared vectors.

7922 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7924 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7926 Mainly changes to support compilation of the device libraries
7927 * src/pic16/device.c: stack is allocated via symbol and not
7928 via literal number. The symbol is placed in the corresponding
7929 position of the data ram
7930 * (pic16_dump_section): relocatable and absolute uninitialized
7931 data are now emitted in sorted order to reduce section naming,
7932 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7933 weren't marked as being in the access bank,
7935 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7937 Added portion of GNU PIC Library under the directory
7938 device/include/pic16 and device/lib/pic16. These files
7939 contain the declarations of SFRs for the PIC18Fxx2 devices.
7940 The directory is initialized via configure from toplevel.
7942 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7944 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7945 the spilllocations to be compared correctly
7947 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7949 * src/SDCCast.c (decorateType): fixed bug introduced today
7951 2004-01-12 Borut Razem <borut.razem AT siol.net>

7967 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7969 * doc/sdccman.lyx: Moved and added some sections, small changes
7970 all over. Telling LaTeX to be less strict with word spacing
7971 to better keep the right margin. Changed some notes about
7972 maintainance of the ports in section 3.2.1 - is it OK like this?
7974 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7976 SDCC source changes:
7977 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8011 UPPER for immediate operands,
8012 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8014 * src/pic16/peeph.def: all peepholes with movff are commented out,
8015 because there is a problem in the pcode peep optimizer,
8016 * src/pic16/ralloc.c: the register allocator can now reuse local
8017 function symbols for another function. This saves register usage.
8018 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8020 Added file src/pic16/NOTES with information about program writing on
8021 the current port version.

8053 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8056 * src/z80/main.c: added missed needLinkerScript flags (more than
8057 one port structure defined in these file)
8058 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8074 needLinkerScript flag
8076 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8077 * src/pic/glue.c: added variable udata_section_name to
8078 override default uninitialized data segment definition for
8079 devices only with SHAREBANK memory (reported from Erik Epetrich)
8080 * (pic14emitOverlay): modified to emit a commented overlay segment
8081 directive when no overlay data exist
8082 * (picglue): modified to emit uninitialized data segment
8083 according to udata_section_name

8093 2004-01-07 Borut Razem <borut.razem AT siol.net>
8095 * support/scripts/sdcc.nsi: update PATH
8096 * support/scripts/sdcc.ico: craeted

8109 include information about variables allocated to the overlay
8112 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8114 * as/mcs51/lkmain.c: Help about -Y option

8126 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8128 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8129 (default behaviour).
8131 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8133 A python script to validate compiler diagnostic messages. It can be
8134 used to verify that sdcc complains about bad c source code and
8135 gives a good location of the error.
8136 * support/valdiag/Makefile,
8137 * support/valdiag/valdiag.py,
8138 * support/valdiag/tests/*

8155 Bug reported from Jesus Calvino-Fraga
8157 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8159 * sdcc.spec: updated
8160 * device/include/Makefile.in: don't install CVS directories
8161 * device/lib/Makefile.in: added removal of CVS directories after install
8162 * doc/Makefile: fixed install, added local_icons
8163 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8164 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8165 * src/ds390/gen.c (genRightShift): fixed bug #870788
8166 * src/SDCCast.c (decorateType): fixed bug #870781
8168 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8170 PIC16 port related changes:
8171 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8172 added variable stackPos,
8174 * gen.c: genCall, assignResultValue: added support for
8175 pushing/retrieving function parameters to/from stack,
8176 genFunction,genEndFunction: setup stack frame for the
8178 genAddrOf: will be changed according to bug 863624
8180 * added files genutils.c and genutils.h which contain gen*
8181 debugged and optimised functions extracted from gen.c
8183 * glue.c: added variable 'externs' which holds extern symbols,
8184 pic16emitRegularMap: is modified to properly handle relocatable
8185 symbols under the new scheme,
8186 pic16createInterruptVect: is modified
8187 pic16printPublics: is modified to emit 'global' assembler directives,
8188 added pic16_printExterns to print extern symbols,
8189 pic16glue: initializes stack/frame pointer in the beginning of
8190 the assembly output. Temporary hack, will be corrected later,
8191 because gplink yet does not support stack and SDCC does not
8192 yet support a type of crt0.o object to create the final binary.
8194 * Removed many lines that contain 8051 legacy code.
8195 * The code is finally placed under a 'code' directive.
8196 * Added port specific options.
8198 * _process_pragma: simplified since now we do not need *special*
8199 include file to define SFR registers. But a separate header
8200 will be needed. This will be developed later.
8201 * _pic16_parseOptions: added, parses port specific options:
8202 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8203 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8204 --preplace-udata-with=
8206 * _pic16_setDefaultOptions: modified to initialize section names,
8207 but hack is temporarly out of order since it needs improvement.
8208 * _pic16_genAssemblerPreamble: configuration words are emitted by
8209 their address instead of their name. This part is incomplete and
8210 supports only the 18Fxx2 devices. Other devices will emit an error
8211 during assembly since they do not contain the same set of config
8213 * _pic16_genIVT: is modified,
8215 * pcode.c: added definitions for some hardware registers that are needed
8217 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8218 All PCI entries are updated. Now LFSR is supported.
8219 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8220 * added pic16_newpCodeOpLit2 to support instructions with
8221 two literal arguments
8222 * pic16_pCode2str: corrected code that emits assembler instructions
8223 with two literal operands and those that have an access bit modifier
8224 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8225 this fixes a bug which caused some labels to be lost, when an
8226 assembler directive was added, i.e. banksel,
8227 * pic16_FixRegisterBanking: improved logic that causes the insertion
8229 * InlineFunction: functions that are called once, are not any more
8230 inlined. This can be a port option in the future,
8232 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8234 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8235 hold the corresponding uninitialized symbols,
8236 * pic16_allocProcessorRegister: registers have explicit marked the
8238 * pic16_allocInternalRegister: registers are explicit marked as
8240 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8241 processing list, so bit registers were lost,
8244 * ralloc.h: added field 'accessBank' and original symbol operand
8245 in register definition,
8246 * removed the field isMapped from register definition,
8248 ** Several functions have been removed from various sources:
8249 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8250 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8251 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8252 pic16_assignRelocatableRegisters
8254 ** others have been introduced:
8255 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8256 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8258 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8260 * support/scripts/inc2h.pl: changed definition of BIT_AT
8261 to emit 'sbit at' instead of 'bit at'. This was a request.
8263 PIC16 port related preliminary changes:
8264 * gen.c: prefixed function popRegFromString with
8265 pic16_ and all references to it corrected
8266 * pcode.c: all pic16_pc_* hardware registers prefixed
8267 with underscore (_),
8268 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8269 * ralloc.c: newReg(): when register is REG_SFR then
8270 set address to rIdx,
8271 pic16_allocProcessorRegister(): marks register wasUsed=0
8272 pic16_writeUsedRegs(): added a call to assign processor
8273 registers via pic16_assignFixedRegisters
8275 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8277 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8278 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8279 variables in unused register banks. Also the SSEG is placed
8280 wherever there is enough space for it, and IDATA can be anywhere
8281 in internal RAM. For now compile using -Wl-Y[stack_size].
8282 The mem file is different for this option as well, since it
8283 makes no sense of talking about DSEG lenght.
8285 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8287 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8288 in certain cases, e.g. when ROM assignment, patch provided
8289 from Albert den Haan.
8291 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8844 not occur if the control variable is involved with a
8845 relational operator.

9334 A few small changes that speed up the peephole optimizer.
9338 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9340 Try to make the peephole optimizer smarter by maintaining
9341 an association between the assembly source code and the
9342 iCodes that originated them. Put this information to use
9343 with a new peephole rule condition "notVolatile" so that
9344 the rules can be aggressive yet still safe.
9349 * src/mcs51/peeph.def
9351 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9355 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9356 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9357 if the left or right operand symbols have the accuse flag set.
9359 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9361 Changed the type of the result of the ! (NOT) operator to char;
9362 previously it returned the same type as the source. This allows
9363 us to eliminate all the genFloatNot functions (all of its target
9364 implementations were very buggy) since !float can use the same
9367 * src/SDCCicode.c (ast2iCode): ! returns char

9376 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9377 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9378 during interrupts. Ensure WSAVE is located at a shared bank address.
9379 2. Fixed page selection in some places
9380 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9381 the registers name strings.
9382 4. Fixed "signed / unsigned compare" compiler warnings.
9383 5. The PIC port manages its own allocation of the general purpose
9384 registers, but makes no attempt to reuse them. As a result when
9385 compiling it soon runs out of general purpose registers. Some
9386 additional code was added to the files pcode.c and device.c to walk
9387 through the function call tree and rename the registers so that they
9397 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9398 genPlus() & genMinus() when the result is the same as left or right

9404 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9406 Made bitfield a distinct type from bit so that bitfields
9407 convert as per ANSI C and bits retain their traditional
9408 boolean style behaviour. Implemented bitfield support in
9416 * src/ds390/gen.c: bit v bitfield split
9417 * src/z80/gen.c: New support for bitfields
9418 * support/regression/tests/bitfields.c: reenabled z80,
9421 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9423 Rules 246.x, 247.x relate to bitfields, the others speed up
9424 access to xdata mapped I/O devices.
9426 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9428 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9430 Cleaned up genPackBits and genUnpackBits and added two helper
9431 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9432 for literal assignments in genPackBits (thanks to Frieder for
9438 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9440 Fixed bug #748310 (pointer to function type mishandled when the
9441 function name is omitted). Also fixed a SIGSEGV when a function
9442 attribute (reentrant, etc) is used on a non-function or on a
9443 function but misplaced before the parameter list.

9470 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9472 Made the constant following the "interrupt" keyword optional. If
9473 omitted, the function will not automatically be given an entry
9474 in the interrupt vector table (similar to #pragma NOIV, but
9475 less syntacticly kludgy). The interrupt number is also now
9476 range checked. Also fixed a bug in the high order bit example

9497 unsigned, but are signed by default
9498 * src/SDCCval.c (constVal): rearranged
9499 * src/SDCCval.c (valMod): preliminary fix
9500 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9952 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9953 the regression tests I'm not brave enough to enable 245.b, 245.c

10005 * src/SDCCmain.c: linkOptions is changed to set *,
10006 added if/endif conditional macros to remove options help
10007 messages from optionsTable when a port is not configured, added
10008 support for the PIc16 port in the ports table, when executing
10009 the compiler with no port specified on command line, a default
10010 port is selected with the new macro DEFAULT_PORT which is
10011 defined in port.h, in setDefaultOptions() linkOptions is removed
10012 from initialization assignment, since now it is a set,
10013 parseCmdLine uses setParseWithComma for linkOptions, in
10014 linkEdit() linkOptions are accessed with new function indexSet()
10015 which returns the i'th item of a set variable. See SDCCset.c, in
10016 linkEdit() when calling buildCmdLine(), added linkOptions as
10017 last argument. Now users can pass arguments to gplink via the
10018 -Wl option, main() uses pic16glue() to glue up pic16 programs

10030 * src/pic16/glue.c: commented out some error producing lines
10031 * src/pic16/main.c: __config directives are commented out to stop
10032 gpasm complaining and test the linkage with gplink, _linkCmd and
10033 _asmCmd changed to be more gplink and gpasm friendly
10034 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10035 produced an error when parsed, peep rule 12 is added to utilize
10036 movff, but it is commented out since the pCode does not support
10037 yet a command with 2 address arguments
10039 2003-05-18 <johan AT balder>
10041 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10068 2003-05-11 Borut Razem <borut.razem AT siol.net>
10070 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

11102 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11104 * in /sdcc/as/mcs51/ changed these files in order to create an
11105 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11106 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11107 following files to include the previous two files: aslink.dsp,
11108 Makefile.aslink, Makefile.bcc, and Makefile.in.
11110 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11111 .adb instead of .cdb
11113 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11115 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11116 value from option --iram-size.
11118 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11120 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11123 2002-09-18 <wiml AT hhhh.org>
11125 * SDCClrange.h: exposed setFromRange() and setToRange()
11126 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11127 packRegsForAccUse() (bug 542397)
11128 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11129 multiple times and emitting the fetch operations more than once
11130 added aopGetUsesAcc() function to allow binary operators to
11131 fetch their operands in the correct order; made genMinus() emit
11132 compact code for X = LITERAL - Y
11134 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11135 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11136 sprintf() in line 1267.
11138 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11139 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11142 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11143 Changes to aslink (All the changes are marked with 'JCF'):
11145 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11148 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11149 area BSEG. Also moves, if possible, the DATA area down into the internal
11150 ram so more space is available.
11152 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11155 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11156 not bytes. Function summary() which creates a memory usage summary
11157 file with extension .mem. Reports of overlaping stack and small stack
11158 size. If the space for the stack is less than 16 bytes aslink trows a
11161 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11162 the 8051. Option 'y' for memory summary output file.
11164 Changes to sdcc (All the changes are marked with 'JCF'):
11166 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11168 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11169 overlaying area for it (uses RegBankUsed[4]).
11171 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11172 bank zero as used by default. By default aslink locates the stack
11173 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11174 the creation of the .mem file. Delegates the allocation of data area
11175 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11176 the begining of the stack area to aslink.
11178 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11179 glue() in SDCCglue.c creates an area for it.
11181 2002-09-03 Borut Razem <borut.razem AT siol.net>
11182 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11183 sdcc/src/pic/glue.c:
11184 introduced atexit() handler for teporay files removal in case of
11185 errors, assertions, ...
11187 2002-08-29 Borut Razem <borut.razem AT siol.net>
11188 * sdcc/support/cpp2/auto-host_vc_in.h:
11189 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11190 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11191 Maybe there is a similar problem with BORLANDC? It should be checked!
11193 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11194 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11195 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11196 was not executed, and the compiler (cl) launched a warning:
11197 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11199 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11200 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11202 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11203 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11205 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11206 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11207 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11208 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11209 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11210 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11211 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11212 - added Release configuration in VS projects
11213 - review of compiler an linker options
11214 - VC .exe files are generated in bin_vc directory, not to interfere
11215 with binaries generated from other projects (cygwin, mingw, bcc ...)
11217 * sdcc/src/yacc.dsp: added
11219 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11220 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11221 and insert the version number definitions from .version
11223 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11225 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

11237 2002-08-10 Borut Razem <borut.razem AT siol.net>
11238 * src/SDCCmain.c (main):
11239 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11240 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11241 The consequence was that some temporary files were not removed.
11244 unification of code in functions tempfilename() and tempfile():
11245 function tempnam() is defined in Visual Studio 6.0 and .NET
11247 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11249 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11250 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11251 - removed compiler command line option /WX: Treats all warnings as errors
11252 - update a list of source files, included into the project
11254 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11255 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11256 changed project type to Generic Project so that can be correcly converted to VS.NET project
11258 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11260 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

11264 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11265 added return 0 statements after assert() to make compiler happy
11267 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11268 added newline in the def file to keep MSC compiler satisfied
11270 * sdcc/src/z80/gen.c:
11271 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11272 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11273 - solved MSC error in function aopDump()
11275 * sdcc_vc.h: define PREFIX as "\\sdcc"
11277 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11450 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11452 * sdcc/src/SDCCloop.c:
11453 Previous fix was not good. basic blocks that have "break" or "return" are
11454 not really partof a loop , but live ranges used in these blocks should
