1264 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1266 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1267 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1269 One basic decision: e.g. src/clean.mk includes further files. In order
1270 to make this work there are two solutions:
1271 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1272 run configure on them. This way they can use
1273 'include $(srcdir)/port-clean.mk'
1274 - always include clean.mk by the Makefile at the same level. To avoid
1275 that `make clean` tries to include and build Makefile.dep the
1276 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1277 implemented, because now even `make uninstall` doesn't create
1278 Makefile.in. clean.mk could be eliminated by pasting it in
1281 * debugger/mcs51/Makefile.in: build own objects from library sources
1282 (SLIB, SDCC) in current directory
1284 * configure, configure.in: renamed --disable-device-lib-build in
1285 --disable-device-lib; added --enable-doc, the required tools are
1286 searched by configure; added result message; the toolchain for the
1287 belonging ports are now only built, if the port is enabled.
1289 * support/regression/*: all output is written in directory gen, because
1290 the fwk and ports directories don't livet in the build tree using vpath
1292 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1293 --disable-device-lib, added --enable-doc, added section VPATH
1295 * sim/ucsim/configure.in,
1296 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1297 z80 are enabled by default
1299 2006-04-24 Raphael Neider <rneider AT web.de>
1301 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1302 to config word, "pic14_"-prefixed some extern functions
1303 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1304 config word has been found
1305 * src/pic/device.h: added prototypes
1306 * src/pic/pcode.c: added "pic14_"-prefix where needed
1307 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1309 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1311 (pic14emitRegularMap): ignore config words,
1312 (pic14createInterruptVect): moved generating __config directives away

1323 fixes #1469504 and #1474602,
1324 (pCodeRegOptimizeRegUsage): fixed typo in comment
1326 2006-04-24 Borut Razem <borut.razem AT siol.net>
1328 * device/examples/main8051.c: deleted - it was removed from CVS
1329 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1330 after the transition to Subversion
1331 * src/SDCCalloc.h: deleted - it was removed from CVS
1332 3.feb.2001 and after that modified 18.feb.2001, so it reappered
1333 after the transition to Subversion

1570 implemented patch 1120823 Thanks to Willy De la Court (normal
1571 interrupts need an interrupt number now if they are made critical),
1572 and enabled nesting of critical functions though not for gbz80
1573 (genCritical, genEndCritical): added functions
1574 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1575 * src/z80/mappings.i: added "ei" to all mappings

1587 the left operand is shorter than the result (c* = lit-c* + int),
1589 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1592 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1594 * src/.version: increased version number to 2.5.5
1595 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1596 linking is done manually in pic16 port's _linkEdit,
1597 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1598 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1599 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1600 allocate asmop as AOP_ACC,
1601 (aopForRemat): added parameter 'bool result' in function declaration,
1602 (pic16_aopGet): return AOP_ACC when accessing WREG,
1603 (pic16_popGetTempReg): minor modification,

1614 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1615 call to allocReg, not by manually allocating a new one,
1616 (pic16_assignRegisters): now before going through the register
1617 allocating functions mark all registers as free. This eliminates some
1618 side effects resulting from peephole parser done earlier in the backbone

1678 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1679 which dumps before the function entry point a data byte which represents
1680 the number of the local variables used by the specified function, added
1681 'xinst' for initial support for Extended Instruction Support,
1682 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1683 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1684 port->fun_prefix anymore (may change later),
1685 (genFunction, genEndFunction): do not store/restore local registers for
1686 _main (this should take care the --main-return command line option in
1688 (genOr): removed some legacy pic-port instructions,
1689 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1690 performing operations with SFR's causes data to be written more than
1691 once to each SFR. Perhaps SFRs should be handled in special cases...
1692 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1694 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1695 into account for stack starting position,

1697 --extended or -y for Extended Instruction Support,
1698 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1699 (deassignLRs): *** perhaps the most important change, old 'for' code
1700 (commented out for reference), didn't account for some registers which
1701 were left marked 'not free' after a pointer operation. The change
1702 reduces register usage a lot in some cases
1704 2006-03-04 Borut Razem <borut.razem AT siol.net>

4064 * device/lib/printf_large.c: removed inline assembly for portability and
4065 readability. Use printf_fast if speed or size are more important.
4066 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4067 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4069 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4071 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4072 prevent compiler warning
4074 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4076 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4077 moved to level 0 and declared as static. Also they are explicit
4078 placed in access bank. This was necessery because some times they
4079 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4080 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4081 optimizations. Currently only compare to unsigned char is implemented,
4082 * src/pic16/gen.c: added fReturnIdx array,
4083 * (struct resolvedIfx) is moved to gen.h and made public,
4084 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4085 * (aopForSym): added an optimization to directly store in stack of
4086 the operand of a SEND iCode,
4087 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4088 but as registers instead (AOP_REG) using the fReturnIdx array,
4089 * (pic16_freeAsmop): remove the freed register from the
4090 _G.sregsAlloc field,
4091 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4092 a compare of 'WREG',
4093 * (pic16_popGetTempRegCond): changed function prototype, now
4094 function takes also a bitVector argument v which holds the current
4095 set of registers that are allocated for stack access by aopForSym,
4096 registers allocated in aopForSym for accessing stack symbols are not
4097 any more part of the functions usedRegs field,
4098 * (genCall): some times aopOp is called for a stack variable to be
4099 send, aopForSym might perform the push, if this is true make sure
4100 that genCall doesn't push the variable twice by testing _G.resDirect,
4101 * (genFunction): changed testing for unspecified interrupt number
4102 from 256 to INTNO_UNSPEC,
4103 * modified selection scheme of frame pointer generation. Previously
4104 if function did use local registers a frame pointer was generated,
4105 now a frame pointer is generated only if function has arguments
4106 (that need PLUSW2 register access), or has stack arguments, or the
4107 compiler is not instructed to omit the frame pointer,
4108 * (genEndFunction): before restoring local registers that were saved
4109 in the function preamble, also restore the registers that *might*
4110 have been allocated for stack access,
4111 * (genRet): removed some old comments,
4112 * (genCmp, the active (RN's) version): added a call to the
4113 pic16_genCmp_special function to perform the compare with a more
4114 robust and optimized way,
4115 * (genInline): a feature has been added in inline code generation,
4116 which allows a wildcard variable substitution when writing inline
4117 assembly. Code is incomplete and experimental therefore undocumented,
4118 * (genCast): changed order of aopOp for result and right to allow
4119 aopForSym to directly load the result if possible,
4120 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4121 perform an optimized compare on some selected special occasions,
4122 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4123 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4124 generate an IVT any more,
4125 * src/pic16/main.c (pic16_optionsTable): added command line option
4127 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4128 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4130 * src/pic16/NOTES: Raphael Neider added in list of active developers
4131 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4132 jumptable_end to prevent bug #,
4133 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4134 inCond and outCond fields,
4135 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4136 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4137 turn off register spilling,
4138 * (packRegsForOneUse): synced with other ports' versions although it
4139 is not used currently,
4140 * (pic16_packRegisters): added an optimization while reading
4141 structure bitfields, some registers may be saved (malloc code is
4142 decreased by 80 bytes)
4144 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4146 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4147 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4148 this can be optimized more?
4150 2005-03-10 Raphael Neider <rneider AT web.de>
4152 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4153 genNearPointerGet): (hopefully) fixed access to bitfields via
4154 pointers (p->bitN = x; and x = p->bitN; failed)

4786 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4788 Adding support for replacing ljmps with sjmps in jumptables
4789 generated for switch statements. For now you need to set the
4790 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4791 Now 4 algorithms for mcs51 jumptable generation are used:
4792 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4793 addresses loaded pc-relative for up to 112 cases and stack-pushing
4794 target addresses loaded with offset from dptr for up to 256 cases.

4820 Large cummulative patch for pic16 port.
4821 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4822 to call when a stack overflow occurs,
4823 * (malloc.h): added CVS Id tag,
4824 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4826 * added libc directory. The current version of LibC contains string
4827 functions, ctype functions and macros and some functions of the
4828 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4829 be extensively tested in the future. Standard disclaimer here.
4830 Library is not automatically build yet. But one can build it by
4831 invoking 'make' inside the libc directory.
4832 * added ADC library under libio. Preliminary version yet.
4834 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4841 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4842 * (pic16_storeForReturn): optimized return of 0,
4843 * (genCmp): experimental code for new genCmp which uses PIC18's
4844 special compare&skip instructions. Initial tests fail some times
4845 with variables grater than 1 byte in size, so new code is disabled,
4846 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4848 * (genCast): began a fix to optimize the casting of a bit to another
4849 bit, now assigning a bitfield to another bitfield will fail, sorry,
4850 * src/pic16/main.c: disabled the use of lr-support feature,
4851 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4852 * added some function prototypes, added function _debugf prototype,

4854 bits with offset (case PO_GPR_BIT),
4855 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4857 * (isBankInstruction): modified to return 0 for no banking instruction,
4858 and 1 for banking instruction,
4859 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4860 caused stop processing pCodes after a inline assembly block,
4861 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4862 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4863 registers when it shouldn't,
4864 * src/pic16/ralloc.c (allocReg): add preliminary support for
4865 supporting a limited set of temporary registers,
4867 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4869 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4870 genDataPointerSet): ensure assignments always copy in MSB to LSB
4872 (loadRegFromAop): recognize CLRH optimization,
4873 (genFunction): optimize RECEIVE iCodes in reentrant functions
4875 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4877 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4878 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4880 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4889 instead of sjmp to ret
4890 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4891 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4893 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7872 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7874 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7875 loaded with the linker search paths (-L arguments) and the libraries
7876 to be linked with the current source (-l arguments). Changes
7877 currently will affect only the pic16 port.
7878 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7879 include path the port specific paths and port specific libraries,
7880 * gplink command now contains the $3 argument,
7881 * src/pic16/device.h,
7882 * src/pic16/device.c,: structure PIC_device is made public and
7883 renamed to PIC16_device, the same for variable Pics which is renamed
7884 to Pics16. Updated all references to them.
7885 * src/pic16/glue.c (pic16glue): corrected bug with code
7886 initialization which bypassed the variable initializations block.
7888 * device/lib/pic16/Makefile.rules: removed --penable-stack from

7896 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7898 Documenting changes from previous commits.
7899 * configure.in (version 1.56),
7900 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7901 when generating output files to configure the pic16 library,
7902 but now I've commented it out, since gputils aren't installed in the
7903 SF compile farm, so library won't compile
7905 * device/lib/Makefile.in (version 1.56): initially I've added in
7906 target 'all' the prerequestive 'model-pic16' so it compiled the
7907 pic16 library, but now I've commented it out for the same reasons
7909 * added targets 'model-pic16' and 'objects-pic16' to compile the
7911 * added target 'port-specific-objects-pic16' to handle the
7912 generated libraries and copy them into the build/ directory
7913 * added target 'clean-intermediate-pic16' to clean intermediate
7914 files into pic16 directory
7915 * in target 'installdirs' added line to create directory pic16 in
7916 the installation path
7918 * device/include/Makefile.in (version 1.11): in target 'install'
7919 added lines to copy all header files to installation path,
7920 * in target 'installdirs' added line create directory for pic16
7921 headers in the installation path
7923 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7936 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7937 option so that it actually works. Made it specific to the z80, since
7938 the gbz80 doesn't have these kinds of I/O ports.
7940 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7942 * device/include/z180.h,

7949 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7950 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7951 portmode; added deprecation warning for bank= and protmode= forms.
7952 Also, guard against buffer overflow.
7953 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7955 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7957 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7958 changed interrupt vector table generation to only emit declared vectors.
7959 * device/include/Makefile.in: added missing backslash
7960 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7962 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7964 Mainly changes to support compilation of the device libraries
7965 * src/pic16/device.c: stack is allocated via symbol and not
7966 via literal number. The symbol is placed in the corresponding
7967 position of the data ram
7968 * (pic16_dump_section): relocatable and absolute uninitialized
7969 data are now emitted in sorted order to reduce section naming,
7970 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7971 weren't marked as being in the access bank,
7973 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7975 Added portion of GNU PIC Library under the directory
7976 device/include/pic16 and device/lib/pic16. These files
7977 contain the declarations of SFRs for the PIC18Fxx2 devices.
7978 The directory is initialized via configure from toplevel.
7980 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7982 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7983 the spilllocations to be compared correctly
7985 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7987 * src/SDCCast.c (decorateType): fixed bug introduced today
7989 2004-01-12 Borut Razem <borut.razem AT siol.net>
7991 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8007 * doc/sdccman.lyx: Moved and added some sections, small changes
8008 all over. Telling LaTeX to be less strict with word spacing
8009 to better keep the right margin. Changed some notes about
8010 maintainance of the ports in section 3.2.1 - is it OK like this?
8012 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8014 SDCC source changes:
8015 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8048 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8049 UPPER for immediate operands,
8050 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8052 * src/pic16/peeph.def: all peepholes with movff are commented out,
8053 because there is a problem in the pcode peep optimizer,
8054 * src/pic16/ralloc.c: the register allocator can now reuse local
8055 function symbols for another function. This saves register usage.
8056 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8058 Added file src/pic16/NOTES with information about program writing on
8059 the current port version.

8068 * src/SDCCmain.c : fixed #872250: -l command line defined library
8069 files are scanned before standard library files
8071 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8088 gen51Code): more efficient parameter receive for --model-large
8091 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8094 * src/z80/main.c: added missed needLinkerScript flags (more than
8095 one port structure defined in these file)
8096 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
8099 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

8112 needLinkerScript flag
8114 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8115 * src/pic/glue.c: added variable udata_section_name to
8116 override default uninitialized data segment definition for
8117 devices only with SHAREBANK memory (reported from Erik Epetrich)
8118 * (pic14emitOverlay): modified to emit a commented overlay segment
8119 directive when no overlay data exist
8120 * (picglue): modified to emit uninitialized data segment
8121 according to udata_section_name

8126 arguments via -W option
8127 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8128 object file from '.rel' to '.o' in port->linker structure,
8129 changed size of fptr from 2 to 3 in port structure
8131 2004-01-07 Borut Razem <borut.razem AT siol.net>
8133 * support/scripts/sdcc.nsi: update PATH
8134 * support/scripts/sdcc.ico: craeted
8136 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8139 * doc/Makefile: fix install
8141 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8143 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8145 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8147 include information about variables allocated to the overlay
8150 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8152 * as/mcs51/lkmain.c: Help about -Y option

8164 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8166 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8167 (default behaviour).
8169 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8171 A python script to validate compiler diagnostic messages. It can be
8172 used to verify that sdcc complains about bad c source code and
8173 gives a good location of the error.
8174 * support/valdiag/Makefile,
8175 * support/valdiag/valdiag.py,
8176 * support/valdiag/tests/*
8178 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8180 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8181 * src/SDCCsymt.c (newEnumType),

8189 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8191 * src/common.h: added ifndef/define/endif macros
8192 around the header file.
8193 Bug reported from Jesus Calvino-Fraga
8195 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8197 * sdcc.spec: updated
8198 * device/include/Makefile.in: don't install CVS directories
8199 * device/lib/Makefile.in: added removal of CVS directories after install
8200 * doc/Makefile: fixed install, added local_icons
8201 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8202 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8203 * src/ds390/gen.c (genRightShift): fixed bug #870788
8204 * src/SDCCast.c (decorateType): fixed bug #870781
8206 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8208 PIC16 port related changes:
8209 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8210 added variable stackPos,
8212 * gen.c: genCall, assignResultValue: added support for
8213 pushing/retrieving function parameters to/from stack,
8214 genFunction,genEndFunction: setup stack frame for the
8216 genAddrOf: will be changed according to bug 863624
8218 * added files genutils.c and genutils.h which contain gen*
8219 debugged and optimised functions extracted from gen.c
8221 * glue.c: added variable 'externs' which holds extern symbols,
8222 pic16emitRegularMap: is modified to properly handle relocatable
8223 symbols under the new scheme,
8224 pic16createInterruptVect: is modified
8225 pic16printPublics: is modified to emit 'global' assembler directives,
8226 added pic16_printExterns to print extern symbols,
8227 pic16glue: initializes stack/frame pointer in the beginning of
8228 the assembly output. Temporary hack, will be corrected later,
8229 because gplink yet does not support stack and SDCC does not
8230 yet support a type of crt0.o object to create the final binary.
8232 * Removed many lines that contain 8051 legacy code.
8233 * The code is finally placed under a 'code' directive.
8234 * Added port specific options.
8236 * _process_pragma: simplified since now we do not need *special*
8237 include file to define SFR registers. But a separate header
8238 will be needed. This will be developed later.
8239 * _pic16_parseOptions: added, parses port specific options:
8240 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8241 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8242 --preplace-udata-with=
8244 * _pic16_setDefaultOptions: modified to initialize section names,
8245 but hack is temporarly out of order since it needs improvement.
8246 * _pic16_genAssemblerPreamble: configuration words are emitted by
8247 their address instead of their name. This part is incomplete and
8248 supports only the 18Fxx2 devices. Other devices will emit an error
8249 during assembly since they do not contain the same set of config
8251 * _pic16_genIVT: is modified,
8253 * pcode.c: added definitions for some hardware registers that are needed
8255 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8256 All PCI entries are updated. Now LFSR is supported.
8257 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8258 * added pic16_newpCodeOpLit2 to support instructions with
8259 two literal arguments
8260 * pic16_pCode2str: corrected code that emits assembler instructions
8261 with two literal operands and those that have an access bit modifier
8262 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8263 this fixes a bug which caused some labels to be lost, when an
8264 assembler directive was added, i.e. banksel,
8265 * pic16_FixRegisterBanking: improved logic that causes the insertion
8267 * InlineFunction: functions that are called once, are not any more
8268 inlined. This can be a port option in the future,
8270 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8272 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8273 hold the corresponding uninitialized symbols,
8274 * pic16_allocProcessorRegister: registers have explicit marked the
8276 * pic16_allocInternalRegister: registers are explicit marked as
8278 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8279 processing list, so bit registers were lost,
8282 * ralloc.h: added field 'accessBank' and original symbol operand
8283 in register definition,
8284 * removed the field isMapped from register definition,
8286 ** Several functions have been removed from various sources:
8287 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8288 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8289 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8290 pic16_assignRelocatableRegisters
8292 ** others have been introduced:
8293 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8294 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8296 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8298 * support/scripts/inc2h.pl: changed definition of BIT_AT
8299 to emit 'sbit at' instead of 'bit at'. This was a request.
8301 PIC16 port related preliminary changes:
8302 * gen.c: prefixed function popRegFromString with
8303 pic16_ and all references to it corrected
8304 * pcode.c: all pic16_pc_* hardware registers prefixed
8305 with underscore (_),
8306 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8307 * ralloc.c: newReg(): when register is REG_SFR then
8308 set address to rIdx,
8309 pic16_allocProcessorRegister(): marks register wasUsed=0
8310 pic16_writeUsedRegs(): added a call to assign processor
8311 registers via pic16_assignFixedRegisters
8313 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8315 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8316 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8317 variables in unused register banks. Also the SSEG is placed
8318 wherever there is enough space for it, and IDATA can be anywhere
8319 in internal RAM. For now compile using -Wl-Y[stack_size].
8320 The mem file is different for this option as well, since it
8321 makes no sense of talking about DSEG lenght.
8323 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8325 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8326 in certain cases, e.g. when ROM assignment, patch provided
8327 from Albert den Haan.
8329 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
8331 Many signedness and type propagation fixes:
8332 * src/SDCCicode.c: made geniCodeCast() static
8333 replaced SPEC_ by IS_ (cosmetic)
8334 (operandOperation): fixed div and mod operation
8335 (usualBinaryConversions): added support for promotion of char
8336 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
8337 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

9333 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9334 copied from genNearPointerSet()
9335 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9336 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9337 If they pop r0/r1 they must be called in the opposite order than aopOp().
9338 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9339 (resp. --stack-auto), prepared for --xstack
9341 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9345 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9347 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9348 these ports have their own __sdcc_external_start()
9350 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9352 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9353 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9354 type for bits was changed. It resulted in bit variables becoming
9355 global, which is not permitted in PIC 14 assembly output.
9357 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9359 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9361 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9363 Z80 and MCS51 linkers complaint if a public symbol is defined
9364 in more than one library module:

9372 A few small changes that speed up the peephole optimizer.
9376 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9378 Try to make the peephole optimizer smarter by maintaining
9379 an association between the assembly source code and the
9380 iCodes that originated them. Put this information to use
9381 with a new peephole rule condition "notVolatile" so that
9382 the rules can be aggressive yet still safe.
9387 * src/mcs51/peeph.def
9389 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9393 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9394 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9395 if the left or right operand symbols have the accuse flag set.
9397 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9399 Changed the type of the result of the ! (NOT) operator to char;
9400 previously it returned the same type as the source. This allows
9401 us to eliminate all the genFloatNot functions (all of its target
9402 implementations were very buggy) since !float can use the same
9405 * src/SDCCicode.c (ast2iCode): ! returns char
9406 * src/mcs51/gen.c (genNot, genNotFloat),
9407 * src/ds390/gen.c (genNot, genNotFloat),
9408 * src/z80/gen.c (genNot, genNotFloat),
9409 * src/pic/gen.c (genNot, genNotFloat),
9410 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9414 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9415 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9416 during interrupts. Ensure WSAVE is located at a shared bank address.
9417 2. Fixed page selection in some places
9418 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9419 the registers name strings.
9420 4. Fixed "signed / unsigned compare" compiler warnings.
9421 5. The PIC port manages its own allocation of the general purpose
9422 registers, but makes no attempt to reuse them. As a result when
9423 compiling it soon runs out of general purpose registers. Some
9424 additional code was added to the files pcode.c and device.c to walk
9425 through the function call tree and rename the registers so that they
9435 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9436 genPlus() & genMinus() when the result is the same as left or right

9442 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9444 Made bitfield a distinct type from bit so that bitfields
9445 convert as per ANSI C and bits retain their traditional
9446 boolean style behaviour. Implemented bitfield support in
9454 * src/ds390/gen.c: bit v bitfield split
9455 * src/z80/gen.c: New support for bitfields
9456 * support/regression/tests/bitfields.c: reenabled z80,
9459 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9461 Rules 246.x, 247.x relate to bitfields, the others speed up
9462 access to xdata mapped I/O devices.
9464 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9466 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9468 Cleaned up genPackBits and genUnpackBits and added two helper
9469 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9470 for literal assignments in genPackBits (thanks to Frieder for
9476 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9478 Fixed bug #748310 (pointer to function type mishandled when the
9479 function name is omitted). Also fixed a SIGSEGV when a function
9480 attribute (reentrant, etc) is used on a non-function or on a
9481 function but misplaced before the parameter list.
9483 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9485 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9486 * support/Util/SDCCerr.h,

9508 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9510 Made the constant following the "interrupt" keyword optional. If
9511 omitted, the function will not automatically be given an entry
9512 in the interrupt vector table (similar to #pragma NOIV, but
9513 less syntacticly kludgy). The interrupt number is also now
9514 range checked. Also fixed a bug in the high order bit example

9528 * src/SDCCicode.c (operandOperation): rewritten some ops
9529 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9530 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9532 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9533 be re-activated by defining REDUCE_LITERALS)
9534 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9535 unsigned, but are signed by default
9536 * src/SDCCval.c (constVal): rearranged
9537 * src/SDCCval.c (valMod): preliminary fix
9538 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10044 added if/endif conditional macros to remove options help
10045 messages from optionsTable when a port is not configured, added
10046 support for the PIc16 port in the ports table, when executing
10047 the compiler with no port specified on command line, a default
10048 port is selected with the new macro DEFAULT_PORT which is
10049 defined in port.h, in setDefaultOptions() linkOptions is removed
10050 from initialization assignment, since now it is a set,
10051 parseCmdLine uses setParseWithComma for linkOptions, in
10052 linkEdit() linkOptions are accessed with new function indexSet()
10053 which returns the i'th item of a set variable. See SDCCset.c, in
10054 linkEdit() when calling buildCmdLine(), added linkOptions as
10055 last argument. Now users can pass arguments to gplink via the
10056 -Wl option, main() uses pic16glue() to glue up pic16 programs

10069 * src/pic16/main.c: __config directives are commented out to stop
10070 gpasm complaining and test the linkage with gplink, _linkCmd and
10071 _asmCmd changed to be more gplink and gpasm friendly
10072 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10073 produced an error when parsed, peep rule 12 is added to utilize
10074 movff, but it is commented out since the pCode does not support
10075 yet a command with 2 address arguments
10077 2003-05-18 <johan AT balder>
10079 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11209 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11210 bank zero as used by default. By default aslink locates the stack
11211 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11212 the creation of the .mem file. Delegates the allocation of data area
11213 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11214 the begining of the stack area to aslink.
11216 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11217 glue() in SDCCglue.c creates an area for it.
11219 2002-09-03 Borut Razem <borut.razem AT siol.net>
11220 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11221 sdcc/src/pic/glue.c:
11222 introduced atexit() handler for teporay files removal in case of
11223 errors, assertions, ...
11225 2002-08-29 Borut Razem <borut.razem AT siol.net>
11226 * sdcc/support/cpp2/auto-host_vc_in.h:
11227 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11228 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11229 Maybe there is a similar problem with BORLANDC? It should be checked!
11231 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11232 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11233 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11234 was not executed, and the compiler (cl) launched a warning:
11235 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11237 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11238 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11240 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11241 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11243 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11244 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11245 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11246 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11247 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11248 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11249 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11250 - added Release configuration in VS projects
11251 - review of compiler an linker options
11252 - VC .exe files are generated in bin_vc directory, not to interfere
11253 with binaries generated from other projects (cygwin, mingw, bcc ...)
11255 * sdcc/src/yacc.dsp: added
11257 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11258 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11259 and insert the version number definitions from .version
11261 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11263 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11264 added - genarate auto-host.h using auto-host_vc_in.h as template
11267 removed from CVS, generated automatically
11269 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11270 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11272 2002-08-11 Borut Razem <borut.razem AT siol.net>
11273 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11275 2002-08-10 Borut Razem <borut.razem AT siol.net>
11276 * src/SDCCmain.c (main):
11277 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11278 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11279 The consequence was that some temporary files were not removed.
11282 unification of code in functions tempfilename() and tempfile():
11283 function tempnam() is defined in Visual Studio 6.0 and .NET
11285 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11287 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11288 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11289 - removed compiler command line option /WX: Treats all warnings as errors
11290 - update a list of source files, included into the project
11292 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11293 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11294 changed project type to Generic Project so that can be correcly converted to VS.NET project
11296 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11298 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11300 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11302 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11303 added return 0 statements after assert() to make compiler happy
11305 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11306 added newline in the def file to keep MSC compiler satisfied
11308 * sdcc/src/z80/gen.c:
11309 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11310 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11311 - solved MSC error in function aopDump()
11313 * sdcc_vc.h: define PREFIX as "\\sdcc"
11315 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11316 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11319 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11320 - Rewrote the register banking algorithm.
11321 - Added pCode live-range analysis to registers (for now, only non-used and
11322 singly-used registers optimized away)

11355 2002-03-28 Johan Knol <johan AT balder>
11357 * src/SDCCval.c: fixed bug #532436
11359 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11364 Added -p option. Allows port dependent processor to be specified.
11367 Initialized the new field char *Processor field to NULL in all ports
11370 Compiler generated registers for interrupt context saving
11371 were not getting allocated.
11373 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11376 Fixed left shift. Will promote the left side of a left shift
11377 if a) left shifting more than size of operand or b) when assigned
11378 to something size > size of left side

11488 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11490 * sdcc/src/SDCCloop.c:
11491 Previous fix was not good. basic blocks that have "break" or "return" are
11492 not really partof a loop , but live ranges used in these blocks should
11493 be live thru the entire loop, so set partOfLoop but don't add them to
11496 2002-02-21 <johan AT FRIJA>
11498 * src/SDCCcse.c: fixed bug #514308
11500 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
