1272 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1274 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1275 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1277 One basic decision: e.g. src/clean.mk includes further files. In order
1278 to make this work there are two solutions:
1279 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1280 run configure on them. This way they can use
1281 'include $(srcdir)/port-clean.mk'
1282 - always include clean.mk by the Makefile at the same level. To avoid
1283 that `make clean` tries to include and build Makefile.dep the
1284 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1285 implemented, because now even `make uninstall` doesn't create
1286 Makefile.in. clean.mk could be eliminated by pasting it in
1289 * debugger/mcs51/Makefile.in: build own objects from library sources
1290 (SLIB, SDCC) in current directory
1292 * configure, configure.in: renamed --disable-device-lib-build in
1293 --disable-device-lib; added --enable-doc, the required tools are
1294 searched by configure; added result message; the toolchain for the
1295 belonging ports are now only built, if the port is enabled.
1297 * support/regression/*: all output is written in directory gen, because
1298 the fwk and ports directories don't livet in the build tree using vpath
1300 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1301 --disable-device-lib, added --enable-doc, added section VPATH
1303 * sim/ucsim/configure.in,
1304 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1305 z80 are enabled by default
1307 2006-04-24 Raphael Neider <rneider AT web.de>
1309 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1310 to config word, "pic14_"-prefixed some extern functions
1311 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1312 config word has been found
1313 * src/pic/device.h: added prototypes
1314 * src/pic/pcode.c: added "pic14_"-prefix where needed
1315 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1317 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1319 (pic14emitRegularMap): ignore config words,
1320 (pic14createInterruptVect): moved generating __config directives away
1321 (picglue): have __config directives emitted
1323 2006-04-24 Borut Razem <borut.razem AT siol.net>
1325 * doc/Makefile: sync with nightly build makefile
1327 2006-04-24 Raphael Neider <rneider AT web.de>
1329 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1330 registers that have not been assigned proper liveranges,
1331 fixes #1469504 and #1474602,
1332 (pCodeRegOptimizeRegUsage): fixed typo in comment
1334 2006-04-24 Borut Razem <borut.razem AT siol.net>
1336 * device/examples/main8051.c: deleted - it was removed from CVS
1337 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1338 after the transition to Subversion
1339 * src/SDCCalloc.h: deleted - it was removed from CVS
1340 3.feb.2001 and after that modified 18.feb.2001, so it reappered
1341 after the transition to Subversion

1579 interrupts need an interrupt number now if they are made critical),
1580 and enabled nesting of critical functions though not for gbz80
1581 (genCritical, genEndCritical): added functions
1582 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1583 * src/z80/mappings.i: added "ei" to all mappings

1595 the left operand is shorter than the result (c* = lit-c* + int),
1597 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1600 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1602 * src/.version: increased version number to 2.5.5
1603 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1604 linking is done manually in pic16 port's _linkEdit,
1605 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1606 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1607 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1608 allocate asmop as AOP_ACC,
1609 (aopForRemat): added parameter 'bool result' in function declaration,
1610 (pic16_aopGet): return AOP_ACC when accessing WREG,
1611 (pic16_popGetTempReg): minor modification,

1622 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1623 call to allocReg, not by manually allocating a new one,
1624 (pic16_assignRegisters): now before going through the register
1625 allocating functions mark all registers as free. This eliminates some
1626 side effects resulting from peephole parser done earlier in the backbone
1628 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1686 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1687 which dumps before the function entry point a data byte which represents
1688 the number of the local variables used by the specified function, added
1689 'xinst' for initial support for Extended Instruction Support,
1690 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1691 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1692 port->fun_prefix anymore (may change later),
1693 (genFunction, genEndFunction): do not store/restore local registers for
1694 _main (this should take care the --main-return command line option in
1696 (genOr): removed some legacy pic-port instructions,
1697 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1698 performing operations with SFR's causes data to be written more than
1699 once to each SFR. Perhaps SFRs should be handled in special cases...
1700 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1702 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1703 into account for stack starting position,

1705 --extended or -y for Extended Instruction Support,
1706 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1707 (deassignLRs): *** perhaps the most important change, old 'for' code
1708 (commented out for reference), didn't account for some registers which
1709 were left marked 'not free' after a pointer operation. The change
1710 reduces register usage a lot in some cases
1712 2006-03-04 Borut Razem <borut.razem AT siol.net>

3987 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3988 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3989 always available in leading double underscore form. The C99 support is
3990 mostly missing, but it's a start.

4072 * device/lib/printf_large.c: removed inline assembly for portability and
4073 readability. Use printf_fast if speed or size are more important.
4074 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4075 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4077 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4079 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4080 prevent compiler warning
4082 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4084 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4085 moved to level 0 and declared as static. Also they are explicit
4086 placed in access bank. This was necessery because some times they
4087 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4088 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4089 optimizations. Currently only compare to unsigned char is implemented,
4090 * src/pic16/gen.c: added fReturnIdx array,
4091 * (struct resolvedIfx) is moved to gen.h and made public,
4092 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4093 * (aopForSym): added an optimization to directly store in stack of
4094 the operand of a SEND iCode,
4095 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4096 but as registers instead (AOP_REG) using the fReturnIdx array,
4097 * (pic16_freeAsmop): remove the freed register from the
4098 _G.sregsAlloc field,
4099 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4100 a compare of 'WREG',
4101 * (pic16_popGetTempRegCond): changed function prototype, now
4102 function takes also a bitVector argument v which holds the current
4103 set of registers that are allocated for stack access by aopForSym,
4104 registers allocated in aopForSym for accessing stack symbols are not
4105 any more part of the functions usedRegs field,
4106 * (genCall): some times aopOp is called for a stack variable to be
4107 send, aopForSym might perform the push, if this is true make sure
4108 that genCall doesn't push the variable twice by testing _G.resDirect,
4109 * (genFunction): changed testing for unspecified interrupt number
4110 from 256 to INTNO_UNSPEC,
4111 * modified selection scheme of frame pointer generation. Previously
4112 if function did use local registers a frame pointer was generated,
4113 now a frame pointer is generated only if function has arguments
4114 (that need PLUSW2 register access), or has stack arguments, or the
4115 compiler is not instructed to omit the frame pointer,
4116 * (genEndFunction): before restoring local registers that were saved
4117 in the function preamble, also restore the registers that *might*
4118 have been allocated for stack access,
4119 * (genRet): removed some old comments,
4120 * (genCmp, the active (RN's) version): added a call to the
4121 pic16_genCmp_special function to perform the compare with a more
4122 robust and optimized way,
4123 * (genInline): a feature has been added in inline code generation,
4124 which allows a wildcard variable substitution when writing inline
4125 assembly. Code is incomplete and experimental therefore undocumented,
4126 * (genCast): changed order of aopOp for result and right to allow
4127 aopForSym to directly load the result if possible,
4128 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4129 perform an optimized compare on some selected special occasions,
4130 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4131 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4132 generate an IVT any more,
4133 * src/pic16/main.c (pic16_optionsTable): added command line option
4135 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4136 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4138 * src/pic16/NOTES: Raphael Neider added in list of active developers
4139 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4140 jumptable_end to prevent bug #,
4141 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4142 inCond and outCond fields,
4143 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4144 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4145 turn off register spilling,
4146 * (packRegsForOneUse): synced with other ports' versions although it
4147 is not used currently,
4148 * (pic16_packRegisters): added an optimization while reading
4149 structure bitfields, some registers may be saved (malloc code is
4150 decreased by 80 bytes)
4152 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4154 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4155 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4156 this can be optimized more?
4158 2005-03-10 Raphael Neider <rneider AT web.de>
4160 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4161 genNearPointerGet): (hopefully) fixed access to bitfields via
4162 pointers (p->bitN = x; and x = p->bitN; failed)
4164 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4794 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4796 Adding support for replacing ljmps with sjmps in jumptables
4797 generated for switch statements. For now you need to set the
4798 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4799 Now 4 algorithms for mcs51 jumptable generation are used:
4800 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4801 addresses loaded pc-relative for up to 112 cases and stack-pushing
4802 target addresses loaded with offset from dptr for up to 256 cases.

4829 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4830 to call when a stack overflow occurs,
4831 * (malloc.h): added CVS Id tag,
4832 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4834 * added libc directory. The current version of LibC contains string
4835 functions, ctype functions and macros and some functions of the
4836 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4837 be extensively tested in the future. Standard disclaimer here.
4838 Library is not automatically build yet. But one can build it by
4839 invoking 'make' inside the libc directory.
4840 * added ADC library under libio. Preliminary version yet.

4849 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4850 * (pic16_storeForReturn): optimized return of 0,
4851 * (genCmp): experimental code for new genCmp which uses PIC18's
4852 special compare&skip instructions. Initial tests fail some times
4853 with variables grater than 1 byte in size, so new code is disabled,
4854 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4856 * (genCast): began a fix to optimize the casting of a bit to another
4857 bit, now assigning a bitfield to another bitfield will fail, sorry,
4858 * src/pic16/main.c: disabled the use of lr-support feature,
4859 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4862 bits with offset (case PO_GPR_BIT),
4863 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4865 * (isBankInstruction): modified to return 0 for no banking instruction,
4866 and 1 for banking instruction,
4867 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4868 caused stop processing pCodes after a inline assembly block,
4869 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4870 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4871 registers when it shouldn't,
4872 * src/pic16/ralloc.c (allocReg): add preliminary support for
4873 supporting a limited set of temporary registers,
4875 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4877 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4878 genDataPointerSet): ensure assignments always copy in MSB to LSB
4880 (loadRegFromAop): recognize CLRH optimization,
4881 (genFunction): optimize RECEIVE iCodes in reentrant functions
4883 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4885 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4899 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4901 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7857 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY
7858 (genMultOneByte): fixed bug in signed vs unsigned multiplication
7859 * sim/ucsim/hc08.src/inst.cc (inst_clr): added missing effective
7860 address fetch for clr instruction

7880 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7882 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7883 loaded with the linker search paths (-L arguments) and the libraries
7884 to be linked with the current source (-l arguments). Changes
7885 currently will affect only the pic16 port.
7886 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7887 include path the port specific paths and port specific libraries,
7888 * gplink command now contains the $3 argument,
7889 * src/pic16/device.h,
7890 * src/pic16/device.c,: structure PIC_device is made public and
7891 renamed to PIC16_device, the same for variable Pics which is renamed
7892 to Pics16. Updated all references to them.
7893 * src/pic16/glue.c (pic16glue): corrected bug with code
7894 initialization which bypassed the variable initializations block.
7896 * device/lib/pic16/Makefile.rules: removed --penable-stack from

7904 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7906 Documenting changes from previous commits.
7907 * configure.in (version 1.56),
7908 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7909 when generating output files to configure the pic16 library,
7910 but now I've commented it out, since gputils aren't installed in the
7911 SF compile farm, so library won't compile
7913 * device/lib/Makefile.in (version 1.56): initially I've added in
7914 target 'all' the prerequestive 'model-pic16' so it compiled the
7915 pic16 library, but now I've commented it out for the same reasons
7917 * added targets 'model-pic16' and 'objects-pic16' to compile the
7919 * added target 'port-specific-objects-pic16' to handle the
7920 generated libraries and copy them into the build/ directory
7921 * added target 'clean-intermediate-pic16' to clean intermediate
7922 files into pic16 directory
7923 * in target 'installdirs' added line to create directory pic16 in
7924 the installation path
7926 * device/include/Makefile.in (version 1.11): in target 'install'
7927 added lines to copy all header files to installation path,
7928 * in target 'installdirs' added line create directory for pic16
7929 headers in the installation path

7944 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7945 option so that it actually works. Made it specific to the z80, since
7946 the gbz80 doesn't have these kinds of I/O ports.
7948 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7950 * device/include/z180.h,

7963 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7965 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7966 changed interrupt vector table generation to only emit declared vectors.
7967 * device/include/Makefile.in: added missing backslash
7968 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7972 Mainly changes to support compilation of the device libraries
7973 * src/pic16/device.c: stack is allocated via symbol and not
7974 via literal number. The symbol is placed in the corresponding
7975 position of the data ram
7976 * (pic16_dump_section): relocatable and absolute uninitialized
7977 data are now emitted in sorted order to reduce section naming,
7978 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7979 weren't marked as being in the access bank,
7981 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7983 Added portion of GNU PIC Library under the directory
7984 device/include/pic16 and device/lib/pic16. These files
7985 contain the declarations of SFRs for the PIC18Fxx2 devices.
7986 The directory is initialized via configure from toplevel.
7988 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7990 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7991 the spilllocations to be compared correctly
7993 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7995 * src/SDCCast.c (decorateType): fixed bug introduced today
7997 2004-01-12 Borut Razem <borut.razem AT siol.net>
7999 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8002 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8004 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8005 in simpler and even better code
8007 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8009 * src/SDCCicode.c (operandOperation): fixed bug #874819

8013 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8015 * doc/sdccman.lyx: Moved and added some sections, small changes
8016 all over. Telling LaTeX to be less strict with word spacing
8017 to better keep the right margin. Changed some notes about
8018 maintainance of the ports in section 3.2.1 - is it OK like this?
8020 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8022 SDCC source changes:
8023 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8056 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8057 UPPER for immediate operands,
8058 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8060 * src/pic16/peeph.def: all peepholes with movff are commented out,
8061 because there is a problem in the pcode peep optimizer,
8062 * src/pic16/ralloc.c: the register allocator can now reuse local
8063 function symbols for another function. This saves register usage.
8064 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8066 Added file src/pic16/NOTES with information about program writing on
8067 the current port version.

8074 2004-01-09 Borut Razem <borut.razem AT siol.net>
8076 * src/SDCCmain.c : fixed #872250: -l command line defined library
8077 files are scanned before standard library files
8079 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8093 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8095 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
8096 gen51Code): more efficient parameter receive for --model-large
8099 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8102 * src/z80/main.c: added missed needLinkerScript flags (more than
8103 one port structure defined in these file)
8104 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
8107 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

8110 * src/port.h: added flag needLinkerScript in port->linker
8111 structure to inform whether to create a .lnk file or not,
8119 * src/z80/main.c: changed appropriately to configure
8120 needLinkerScript flag
8122 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8123 * src/pic/glue.c: added variable udata_section_name to
8124 override default uninitialized data segment definition for
8125 devices only with SHAREBANK memory (reported from Erik Epetrich)
8126 * (pic14emitOverlay): modified to emit a commented overlay segment
8127 directive when no overlay data exist
8128 * (picglue): modified to emit uninitialized data segment
8129 according to udata_section_name
8130 * src/pic/main.c (_pic14_parseOptions): added command line

8134 arguments via -W option
8135 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8136 object file from '.rel' to '.o' in port->linker structure,
8137 changed size of fptr from 2 to 3 in port structure
8139 2004-01-07 Borut Razem <borut.razem AT siol.net>
8141 * support/scripts/sdcc.nsi: update PATH
8142 * support/scripts/sdcc.ico: craeted
8144 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8146 * device/include/Makefile.in: fix install
8147 * doc/Makefile: fix install
8149 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8151 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8153 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
8154 how the function variable allocation summary is displayed; also
8155 include information about variables allocated to the overlay
8158 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8160 * as/mcs51/lkmain.c: Help about -Y option

8169 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8170 LEFT_OP (left shift)
8172 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8174 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8175 (default behaviour).
8177 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8179 A python script to validate compiler diagnostic messages. It can be
8180 used to verify that sdcc complains about bad c source code and
8181 gives a good location of the error.
8182 * support/valdiag/Makefile,
8183 * support/valdiag/valdiag.py,
8184 * support/valdiag/tests/*
8186 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8188 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8189 * src/SDCCsymt.c (newEnumType),
8191 * support/Util/SDCCerr.c,
8192 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported

8197 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8199 * src/common.h: added ifndef/define/endif macros
8200 around the header file.
8201 Bug reported from Jesus Calvino-Fraga
8203 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8205 * sdcc.spec: updated
8206 * device/include/Makefile.in: don't install CVS directories
8207 * device/lib/Makefile.in: added removal of CVS directories after install
8208 * doc/Makefile: fixed install, added local_icons
8209 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8210 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8211 * src/ds390/gen.c (genRightShift): fixed bug #870788
8212 * src/SDCCast.c (decorateType): fixed bug #870781
8214 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8216 PIC16 port related changes:
8217 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8218 added variable stackPos,
8220 * gen.c: genCall, assignResultValue: added support for
8221 pushing/retrieving function parameters to/from stack,
8222 genFunction,genEndFunction: setup stack frame for the
8224 genAddrOf: will be changed according to bug 863624
8226 * added files genutils.c and genutils.h which contain gen*
8227 debugged and optimised functions extracted from gen.c
8229 * glue.c: added variable 'externs' which holds extern symbols,
8230 pic16emitRegularMap: is modified to properly handle relocatable
8231 symbols under the new scheme,
8232 pic16createInterruptVect: is modified
8233 pic16printPublics: is modified to emit 'global' assembler directives,
8234 added pic16_printExterns to print extern symbols,
8235 pic16glue: initializes stack/frame pointer in the beginning of
8236 the assembly output. Temporary hack, will be corrected later,
8237 because gplink yet does not support stack and SDCC does not
8238 yet support a type of crt0.o object to create the final binary.
8240 * Removed many lines that contain 8051 legacy code.
8241 * The code is finally placed under a 'code' directive.
8242 * Added port specific options.
8244 * _process_pragma: simplified since now we do not need *special*
8245 include file to define SFR registers. But a separate header
8246 will be needed. This will be developed later.
8247 * _pic16_parseOptions: added, parses port specific options:
8248 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8249 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8250 --preplace-udata-with=
8252 * _pic16_setDefaultOptions: modified to initialize section names,
8253 but hack is temporarly out of order since it needs improvement.
8254 * _pic16_genAssemblerPreamble: configuration words are emitted by
8255 their address instead of their name. This part is incomplete and
8256 supports only the 18Fxx2 devices. Other devices will emit an error
8257 during assembly since they do not contain the same set of config
8259 * _pic16_genIVT: is modified,
8261 * pcode.c: added definitions for some hardware registers that are needed
8263 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8264 All PCI entries are updated. Now LFSR is supported.
8265 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8266 * added pic16_newpCodeOpLit2 to support instructions with
8267 two literal arguments
8268 * pic16_pCode2str: corrected code that emits assembler instructions
8269 with two literal operands and those that have an access bit modifier
8270 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8271 this fixes a bug which caused some labels to be lost, when an
8272 assembler directive was added, i.e. banksel,
8273 * pic16_FixRegisterBanking: improved logic that causes the insertion
8275 * InlineFunction: functions that are called once, are not any more
8276 inlined. This can be a port option in the future,
8278 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8280 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8281 hold the corresponding uninitialized symbols,
8282 * pic16_allocProcessorRegister: registers have explicit marked the
8284 * pic16_allocInternalRegister: registers are explicit marked as
8286 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8287 processing list, so bit registers were lost,
8290 * ralloc.h: added field 'accessBank' and original symbol operand
8291 in register definition,
8292 * removed the field isMapped from register definition,
8294 ** Several functions have been removed from various sources:
8295 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8296 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8297 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8298 pic16_assignRelocatableRegisters
8300 ** others have been introduced:
8301 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8302 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8304 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8306 * support/scripts/inc2h.pl: changed definition of BIT_AT
8307 to emit 'sbit at' instead of 'bit at'. This was a request.
8309 PIC16 port related preliminary changes:
8310 * gen.c: prefixed function popRegFromString with
8311 pic16_ and all references to it corrected
8312 * pcode.c: all pic16_pc_* hardware registers prefixed
8313 with underscore (_),
8314 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8315 * ralloc.c: newReg(): when register is REG_SFR then
8316 set address to rIdx,
8317 pic16_allocProcessorRegister(): marks register wasUsed=0
8318 pic16_writeUsedRegs(): added a call to assign processor
8319 registers via pic16_assignFixedRegisters
8321 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8323 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8324 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8325 variables in unused register banks. Also the SSEG is placed
8326 wherever there is enough space for it, and IDATA can be anywhere
8327 in internal RAM. For now compile using -Wl-Y[stack_size].
8328 The mem file is different for this option as well, since it
8329 makes no sense of talking about DSEG lenght.
8331 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8333 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8334 in certain cases, e.g. when ROM assignment, patch provided
8335 from Albert den Haan.
8337 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9334 before instructions that use the _STATUS register
9336 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9338 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9339 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9340 fetching of the pointer
9341 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9342 copied from genNearPointerSet()
9343 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9344 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9345 If they pop r0/r1 they must be called in the opposite order than aopOp().
9346 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9347 (resp. --stack-auto), prepared for --xstack
9349 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9356 these ports have their own __sdcc_external_start()
9358 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9360 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9361 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9362 type for bits was changed. It resulted in bit variables becoming
9363 global, which is not permitted in PIC 14 assembly output.
9365 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9367 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9369 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9371 Z80 and MCS51 linkers complaint if a public symbol is defined

9380 A few small changes that speed up the peephole optimizer.
9384 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9386 Try to make the peephole optimizer smarter by maintaining
9387 an association between the assembly source code and the
9388 iCodes that originated them. Put this information to use
9389 with a new peephole rule condition "notVolatile" so that
9390 the rules can be aggressive yet still safe.
9395 * src/mcs51/peeph.def
9397 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9401 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9402 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9403 if the left or right operand symbols have the accuse flag set.
9405 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9407 Changed the type of the result of the ! (NOT) operator to char;
9408 previously it returned the same type as the source. This allows
9409 us to eliminate all the genFloatNot functions (all of its target
9410 implementations were very buggy) since !float can use the same
9413 * src/SDCCicode.c (ast2iCode): ! returns char
9414 * src/mcs51/gen.c (genNot, genNotFloat),
9415 * src/ds390/gen.c (genNot, genNotFloat),
9416 * src/z80/gen.c (genNot, genNotFloat),
9417 * src/pic/gen.c (genNot, genNotFloat),
9418 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9422 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9423 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9424 during interrupts. Ensure WSAVE is located at a shared bank address.
9425 2. Fixed page selection in some places
9426 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9427 the registers name strings.
9428 4. Fixed "signed / unsigned compare" compiler warnings.
9429 5. The PIC port manages its own allocation of the general purpose
9430 registers, but makes no attempt to reuse them. As a result when
9431 compiling it soon runs out of general purpose registers. Some
9432 additional code was added to the files pcode.c and device.c to walk
9433 through the function call tree and rename the registers so that they
9443 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9444 genPlus() & genMinus() when the result is the same as left or right

9450 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9452 Made bitfield a distinct type from bit so that bitfields
9453 convert as per ANSI C and bits retain their traditional
9454 boolean style behaviour. Implemented bitfield support in
9462 * src/ds390/gen.c: bit v bitfield split
9463 * src/z80/gen.c: New support for bitfields
9464 * support/regression/tests/bitfields.c: reenabled z80,
9467 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9469 Rules 246.x, 247.x relate to bitfields, the others speed up
9470 access to xdata mapped I/O devices.
9472 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9474 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9476 Cleaned up genPackBits and genUnpackBits and added two helper
9477 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9478 for literal assignments in genPackBits (thanks to Frieder for
9484 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9486 Fixed bug #748310 (pointer to function type mishandled when the
9487 function name is omitted). Also fixed a SIGSEGV when a function
9488 attribute (reentrant, etc) is used on a non-function or on a
9489 function but misplaced before the parameter list.
9491 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9493 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9494 * support/Util/SDCCerr.h,

9516 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9518 Made the constant following the "interrupt" keyword optional. If
9519 omitted, the function will not automatically be given an entry
9520 in the interrupt vector table (similar to #pragma NOIV, but
9521 less syntacticly kludgy). The interrupt number is also now
9522 range checked. Also fixed a bug in the high order bit example

9536 * src/SDCCicode.c (operandOperation): rewritten some ops
9537 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9538 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9540 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9541 be re-activated by defining REDUCE_LITERALS)
9542 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9543 unsigned, but are signed by default
9544 * src/SDCCval.c (constVal): rearranged
9545 * src/SDCCval.c (valMod): preliminary fix
9546 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10052 added if/endif conditional macros to remove options help
10053 messages from optionsTable when a port is not configured, added
10054 support for the PIc16 port in the ports table, when executing
10055 the compiler with no port specified on command line, a default
10056 port is selected with the new macro DEFAULT_PORT which is
10057 defined in port.h, in setDefaultOptions() linkOptions is removed
10058 from initialization assignment, since now it is a set,
10059 parseCmdLine uses setParseWithComma for linkOptions, in
10060 linkEdit() linkOptions are accessed with new function indexSet()
10061 which returns the i'th item of a set variable. See SDCCset.c, in
10062 linkEdit() when calling buildCmdLine(), added linkOptions as
10063 last argument. Now users can pass arguments to gplink via the
10064 -Wl option, main() uses pic16glue() to glue up pic16 programs

10078 gpasm complaining and test the linkage with gplink, _linkCmd and
10079 _asmCmd changed to be more gplink and gpasm friendly
10080 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10081 produced an error when parsed, peep rule 12 is added to utilize
10082 movff, but it is commented out since the pCode does not support
10083 yet a command with 2 address arguments
10085 2003-05-18 <johan AT balder>
10087 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11194 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11195 area BSEG. Also moves, if possible, the DATA area down into the internal
11196 ram so more space is available.
11198 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11201 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11202 not bytes. Function summary() which creates a memory usage summary
11203 file with extension .mem. Reports of overlaping stack and small stack
11204 size. If the space for the stack is less than 16 bytes aslink trows a
11207 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11208 the 8051. Option 'y' for memory summary output file.
11210 Changes to sdcc (All the changes are marked with 'JCF'):
11212 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11214 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11215 overlaying area for it (uses RegBankUsed[4]).
11217 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11218 bank zero as used by default. By default aslink locates the stack
11219 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11220 the creation of the .mem file. Delegates the allocation of data area
11221 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11222 the begining of the stack area to aslink.
11224 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11225 glue() in SDCCglue.c creates an area for it.
11227 2002-09-03 Borut Razem <borut.razem AT siol.net>
11228 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11229 sdcc/src/pic/glue.c:
11230 introduced atexit() handler for teporay files removal in case of
11231 errors, assertions, ...
11233 2002-08-29 Borut Razem <borut.razem AT siol.net>
11234 * sdcc/support/cpp2/auto-host_vc_in.h:
11235 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11236 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11237 Maybe there is a similar problem with BORLANDC? It should be checked!
11239 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11240 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11241 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11242 was not executed, and the compiler (cl) launched a warning:
11243 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11245 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11246 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11252 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11253 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11254 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11255 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11256 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11257 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11258 - added Release configuration in VS projects
11259 - review of compiler an linker options
11260 - VC .exe files are generated in bin_vc directory, not to interfere
11261 with binaries generated from other projects (cygwin, mingw, bcc ...)
11263 * sdcc/src/yacc.dsp: added
11265 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11266 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11267 and insert the version number definitions from .version
11269 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11271 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11272 added - genarate auto-host.h using auto-host_vc_in.h as template
11275 removed from CVS, generated automatically
11277 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11278 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11280 2002-08-11 Borut Razem <borut.razem AT siol.net>
11281 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11283 2002-08-10 Borut Razem <borut.razem AT siol.net>
11284 * src/SDCCmain.c (main):
11285 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11286 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11287 The consequence was that some temporary files were not removed.
11290 unification of code in functions tempfilename() and tempfile():
11291 function tempnam() is defined in Visual Studio 6.0 and .NET
11293 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11295 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11296 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11297 - removed compiler command line option /WX: Treats all warnings as errors
11298 - update a list of source files, included into the project
11300 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11301 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11302 changed project type to Generic Project so that can be correcly converted to VS.NET project
11304 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11306 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11308 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11310 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11311 added return 0 statements after assert() to make compiler happy
11313 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11314 added newline in the def file to keep MSC compiler satisfied
11316 * sdcc/src/z80/gen.c:
11317 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11318 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11319 - solved MSC error in function aopDump()
11321 * sdcc_vc.h: define PREFIX as "\\sdcc"
11323 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11496 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11498 * sdcc/src/SDCCloop.c:
11499 Previous fix was not good. basic blocks that have "break" or "return" are
11500 not really partof a loop , but live ranges used in these blocks should
11501 be live thru the entire loop, so set partOfLoop but don't add them to
11504 2002-02-21 <johan AT FRIJA>
11506 * src/SDCCcse.c: fixed bug #514308
11508 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
