1160 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1162 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1163 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1165 One basic decision: e.g. src/clean.mk includes further files. In order
1166 to make this work there are two solutions:
1167 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1168 run configure on them. This way they can use
1169 'include $(srcdir)/port-clean.mk'
1170 - always include clean.mk by the Makefile at the same level. To avoid
1171 that `make clean` tries to include and build Makefile.dep the
1172 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1173 implemented, because now even `make uninstall` doesn't create
1174 Makefile.in. clean.mk could be eliminated by pasting it in
1177 * debugger/mcs51/Makefile.in: build own objects from library sources
1178 (SLIB, SDCC) in current directory
1180 * configure, configure.in: renamed --disable-device-lib-build in
1181 --disable-device-lib; added --enable-doc, the required tools are
1182 searched by configure; added result message; the toolchain for the
1183 belonging ports are now only built, if the port is enabled.
1185 * support/regression/*: all output is written in directory gen, because
1186 the fwk and ports directories don't livet in the build tree using vpath
1188 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1189 --disable-device-lib, added --enable-doc, added section VPATH
1191 * sim/ucsim/configure.in,
1192 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1193 z80 are enabled by default
1195 2006-04-24 Raphael Neider <rneider AT web.de>
1197 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1198 to config word, "pic14_"-prefixed some extern functions
1199 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1200 config word has been found
1201 * src/pic/device.h: added prototypes
1202 * src/pic/pcode.c: added "pic14_"-prefix where needed
1203 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1205 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1207 (pic14emitRegularMap): ignore config words,
1208 (pic14createInterruptVect): moved generating __config directives away
1209 (picglue): have __config directives emitted
1211 2006-04-24 Borut Razem <borut.razem AT siol.net>

1218 registers that have not been assigned proper liveranges,
1219 fixes #1469504 and #1474602,
1220 (pCodeRegOptimizeRegUsage): fixed typo in comment

1467 interrupts need an interrupt number now if they are made critical),
1468 and enabled nesting of critical functions though not for gbz80
1469 (genCritical, genEndCritical): added functions
1470 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1471 * src/z80/mappings.i: added "ei" to all mappings

1485 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1488 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1490 * src/.version: increased version number to 2.5.5
1491 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1492 linking is done manually in pic16 port's _linkEdit,
1493 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1494 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1495 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1496 allocate asmop as AOP_ACC,
1497 (aopForRemat): added parameter 'bool result' in function declaration,
1498 (pic16_aopGet): return AOP_ACC when accessing WREG,
1499 (pic16_popGetTempReg): minor modification,

1510 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1511 call to allocReg, not by manually allocating a new one,
1512 (pic16_assignRegisters): now before going through the register
1513 allocating functions mark all registers as free. This eliminates some
1514 side effects resulting from peephole parser done earlier in the backbone
1516 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1574 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1575 which dumps before the function entry point a data byte which represents
1576 the number of the local variables used by the specified function, added
1577 'xinst' for initial support for Extended Instruction Support,
1578 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1579 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1580 port->fun_prefix anymore (may change later),
1581 (genFunction, genEndFunction): do not store/restore local registers for
1582 _main (this should take care the --main-return command line option in
1584 (genOr): removed some legacy pic-port instructions,
1585 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1586 performing operations with SFR's causes data to be written more than
1587 once to each SFR. Perhaps SFRs should be handled in special cases...
1588 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1590 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1591 into account for stack starting position,

1593 --extended or -y for Extended Instruction Support,
1594 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1595 (deassignLRs): *** perhaps the most important change, old 'for' code
1596 (commented out for reference), didn't account for some registers which
1597 were left marked 'not free' after a pointer operation. The change
1598 reduces register usage a lot in some cases

3852 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3853 information on the new functions of the c library and more...
3855 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3857 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
3859 2005-03-26 Raphael Neider <rneider AT web.de>
3861 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
3862 if condition == CARRY)
3863 * (genCmp): adapted to new genSkipc semantics
3864 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3865 on rIfx (genCmp was broken)
3867 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3869 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3870 * src/z80/main.c (_keywords[]),
3871 * src/SDCCglobal.h (struct options),
3873 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3874 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3875 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3876 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3877 always available in leading double underscore form. The C99 support is
3878 mostly missing, but it's a start.
3879 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3880 reserved identifier "__data".
3882 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3884 * src/mcs51/peeph.def: fixed bug 1170013

3926 immedDom() returning wrong block; probably fixes bug #1160833)
3928 2005-03-20 Borut Razem <borut.razem AT siol.net>
3930 * support/scripts/inc2h.pl: WIN32 port

3934 * device/lib/makefile.in: added abs.c and labs.c
3936 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3938 * device/include/stdint.h: added
3939 * device/lib/abs.c: added
3940 * device/lib/labs.c: added
3941 * device/include/stdlib.h: added abs() and labs() prototypes

3956 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3958 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3960 * device/lib/printf_large.c: removed inline assembly for portability and
3961 readability. Use printf_fast if speed or size are more important.
3962 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3963 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3965 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3967 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3968 prevent compiler warning
3970 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3972 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3973 moved to level 0 and declared as static. Also they are explicit
3974 placed in access bank. This was necessery because some times they
3975 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3976 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3977 optimizations. Currently only compare to unsigned char is implemented,
3978 * src/pic16/gen.c: added fReturnIdx array,
3979 * (struct resolvedIfx) is moved to gen.h and made public,
3980 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3981 * (aopForSym): added an optimization to directly store in stack of
3982 the operand of a SEND iCode,
3983 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3984 but as registers instead (AOP_REG) using the fReturnIdx array,
3985 * (pic16_freeAsmop): remove the freed register from the
3986 _G.sregsAlloc field,
3987 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3988 a compare of 'WREG',
3989 * (pic16_popGetTempRegCond): changed function prototype, now
3990 function takes also a bitVector argument v which holds the current
3991 set of registers that are allocated for stack access by aopForSym,
3992 registers allocated in aopForSym for accessing stack symbols are not
3993 any more part of the functions usedRegs field,
3994 * (genCall): some times aopOp is called for a stack variable to be
3995 send, aopForSym might perform the push, if this is true make sure
3996 that genCall doesn't push the variable twice by testing _G.resDirect,
3997 * (genFunction): changed testing for unspecified interrupt number
3998 from 256 to INTNO_UNSPEC,
3999 * modified selection scheme of frame pointer generation. Previously
4000 if function did use local registers a frame pointer was generated,
4001 now a frame pointer is generated only if function has arguments
4002 (that need PLUSW2 register access), or has stack arguments, or the
4003 compiler is not instructed to omit the frame pointer,
4004 * (genEndFunction): before restoring local registers that were saved
4005 in the function preamble, also restore the registers that *might*
4006 have been allocated for stack access,
4007 * (genRet): removed some old comments,
4008 * (genCmp, the active (RN's) version): added a call to the
4009 pic16_genCmp_special function to perform the compare with a more
4010 robust and optimized way,
4011 * (genInline): a feature has been added in inline code generation,
4012 which allows a wildcard variable substitution when writing inline
4013 assembly. Code is incomplete and experimental therefore undocumented,
4014 * (genCast): changed order of aopOp for result and right to allow
4015 aopForSym to directly load the result if possible,
4016 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4017 perform an optimized compare on some selected special occasions,
4018 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4019 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4020 generate an IVT any more,
4021 * src/pic16/main.c (pic16_optionsTable): added command line option
4023 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4024 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4026 * src/pic16/NOTES: Raphael Neider added in list of active developers
4027 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4028 jumptable_end to prevent bug #,
4029 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4030 inCond and outCond fields,
4031 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4032 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4033 turn off register spilling,
4034 * (packRegsForOneUse): synced with other ports' versions although it
4035 is not used currently,
4036 * (pic16_packRegisters): added an optimization while reading
4037 structure bitfields, some registers may be saved (malloc code is
4038 decreased by 80 bytes)
4040 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4042 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4043 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4044 this can be optimized more?
4046 2005-03-10 Raphael Neider <rneider AT web.de>
4048 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4049 genNearPointerGet): (hopefully) fixed access to bitfields via
4050 pointers (p->bitN = x; and x = p->bitN; failed)
4052 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4054 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4239 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4240 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4241 this might fix SIGSEGVs on MinGW...
4242 * src/SDCCopt.c (killDeadCode): restored original behaviour
4243 (volatile operands might get thrown away though)
4245 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4285 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4286 reflect stack model used,
4287 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
4288 on stack return NULL,

4293 of the operands is volatile. Fixes #1020220
4295 2005-01-22 Daniel Winkler <post AT danielwinkler.de>

4685 generated for switch statements. For now you need to set the
4686 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4687 Now 4 algorithms for mcs51 jumptable generation are used:
4688 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4689 addresses loaded pc-relative for up to 112 cases and stack-pushing
4690 target addresses loaded with offset from dptr for up to 256 cases.

7721 added support for multiple code pages and multiple RAM banks on the
7722 PIC 14 port. The ASM files now no longer simply assume all the
7723 code / RAM are in the same page / bank. This means the linker can
7724 safely allocate code/RAM of separate ASM files to different pages/banks.

7768 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7770 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7771 loaded with the linker search paths (-L arguments) and the libraries
7772 to be linked with the current source (-l arguments). Changes
7773 currently will affect only the pic16 port.
7774 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7775 include path the port specific paths and port specific libraries,
7776 * gplink command now contains the $3 argument,
7777 * src/pic16/device.h,
7778 * src/pic16/device.c,: structure PIC_device is made public and
7779 renamed to PIC16_device, the same for variable Pics which is renamed

7794 Documenting changes from previous commits.
7795 * configure.in (version 1.56),
7796 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7797 when generating output files to configure the pic16 library,
7798 but now I've commented it out, since gputils aren't installed in the
7799 SF compile farm, so library won't compile
7801 * device/lib/Makefile.in (version 1.56): initially I've added in
7802 target 'all' the prerequestive 'model-pic16' so it compiled the
7803 pic16 library, but now I've commented it out for the same reasons
7805 * added targets 'model-pic16' and 'objects-pic16' to compile the
7807 * added target 'port-specific-objects-pic16' to handle the
7808 generated libraries and copy them into the build/ directory
7809 * added target 'clean-intermediate-pic16' to clean intermediate
7810 files into pic16 directory
7811 * in target 'installdirs' added line to create directory pic16 in
7812 the installation path
7814 * device/include/Makefile.in (version 1.11): in target 'install'
7815 added lines to copy all header files to installation path,
7816 * in target 'installdirs' added line create directory for pic16
7817 headers in the installation path
7819 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7830 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7832 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7833 option so that it actually works. Made it specific to the z80, since
7834 the gbz80 doesn't have these kinds of I/O ports.
7836 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7838 * device/include/z180.h,

7904 all over. Telling LaTeX to be less strict with word spacing
7905 to better keep the right margin. Changed some notes about
7906 maintainance of the ports in section 3.2.1 - is it OK like this?
7908 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7946 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7948 * src/pic16/peeph.def: all peepholes with movff are commented out,
7949 because there is a problem in the pcode peep optimizer,
7950 * src/pic16/ralloc.c: the register allocator can now reuse local

8043 include information about variables allocated to the overlay
8046 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8048 * as/mcs51/lkmain.c: Help about -Y option

8060 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8062 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8063 (default behaviour).
8065 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8067 A python script to validate compiler diagnostic messages. It can be
8068 used to verify that sdcc complains about bad c source code and
8069 gives a good location of the error.
8070 * support/valdiag/Makefile,
8071 * support/valdiag/valdiag.py,
8072 * support/valdiag/tests/*
8074 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8087 * src/common.h: added ifndef/define/endif macros
8088 around the header file.
8089 Bug reported from Jesus Calvino-Fraga
8091 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8093 * sdcc.spec: updated
8094 * device/include/Makefile.in: don't install CVS directories
8095 * device/lib/Makefile.in: added removal of CVS directories after install
8096 * doc/Makefile: fixed install, added local_icons
8097 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8098 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8099 * src/ds390/gen.c (genRightShift): fixed bug #870788
8100 * src/SDCCast.c (decorateType): fixed bug #870781
8102 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8104 PIC16 port related changes:
8105 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8106 added variable stackPos,
8108 * gen.c: genCall, assignResultValue: added support for
8109 pushing/retrieving function parameters to/from stack,
8110 genFunction,genEndFunction: setup stack frame for the
8112 genAddrOf: will be changed according to bug 863624
8114 * added files genutils.c and genutils.h which contain gen*
8115 debugged and optimised functions extracted from gen.c
8117 * glue.c: added variable 'externs' which holds extern symbols,
8118 pic16emitRegularMap: is modified to properly handle relocatable
8119 symbols under the new scheme,
8120 pic16createInterruptVect: is modified
8121 pic16printPublics: is modified to emit 'global' assembler directives,
8122 added pic16_printExterns to print extern symbols,
8123 pic16glue: initializes stack/frame pointer in the beginning of
8124 the assembly output. Temporary hack, will be corrected later,
8125 because gplink yet does not support stack and SDCC does not
8126 yet support a type of crt0.o object to create the final binary.
8128 * Removed many lines that contain 8051 legacy code.
8129 * The code is finally placed under a 'code' directive.
8130 * Added port specific options.
8132 * _process_pragma: simplified since now we do not need *special*
8133 include file to define SFR registers. But a separate header
8134 will be needed. This will be developed later.
8135 * _pic16_parseOptions: added, parses port specific options:
8136 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8137 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8138 --preplace-udata-with=
8140 * _pic16_setDefaultOptions: modified to initialize section names,
8141 but hack is temporarly out of order since it needs improvement.
8142 * _pic16_genAssemblerPreamble: configuration words are emitted by
8143 their address instead of their name. This part is incomplete and
8144 supports only the 18Fxx2 devices. Other devices will emit an error
8145 during assembly since they do not contain the same set of config
8147 * _pic16_genIVT: is modified,
8149 * pcode.c: added definitions for some hardware registers that are needed
8151 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8152 All PCI entries are updated. Now LFSR is supported.
8153 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8154 * added pic16_newpCodeOpLit2 to support instructions with
8155 two literal arguments
8156 * pic16_pCode2str: corrected code that emits assembler instructions
8157 with two literal operands and those that have an access bit modifier
8158 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8159 this fixes a bug which caused some labels to be lost, when an
8160 assembler directive was added, i.e. banksel,
8161 * pic16_FixRegisterBanking: improved logic that causes the insertion
8163 * InlineFunction: functions that are called once, are not any more
8164 inlined. This can be a port option in the future,
8166 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8168 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8169 hold the corresponding uninitialized symbols,
8170 * pic16_allocProcessorRegister: registers have explicit marked the
8172 * pic16_allocInternalRegister: registers are explicit marked as
8174 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8175 processing list, so bit registers were lost,
8178 * ralloc.h: added field 'accessBank' and original symbol operand
8179 in register definition,
8180 * removed the field isMapped from register definition,
8182 ** Several functions have been removed from various sources:
8183 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8184 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8185 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8186 pic16_assignRelocatableRegisters
8188 ** others have been introduced:
8189 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8190 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8192 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8194 * support/scripts/inc2h.pl: changed definition of BIT_AT
8195 to emit 'sbit at' instead of 'bit at'. This was a request.
8197 PIC16 port related preliminary changes:
8198 * gen.c: prefixed function popRegFromString with
8199 pic16_ and all references to it corrected
8200 * pcode.c: all pic16_pc_* hardware registers prefixed
8201 with underscore (_),
8202 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8203 * ralloc.c: newReg(): when register is REG_SFR then
8204 set address to rIdx,
8205 pic16_allocProcessorRegister(): marks register wasUsed=0
8206 pic16_writeUsedRegs(): added a call to assign processor
8207 registers via pic16_assignFixedRegisters
8209 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8211 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8212 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8213 variables in unused register banks. Also the SSEG is placed
8214 wherever there is enough space for it, and IDATA can be anywhere
8215 in internal RAM. For now compile using -Wl-Y[stack_size].
8216 The mem file is different for this option as well, since it
8217 makes no sense of talking about DSEG lenght.
8219 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8221 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8222 in certain cases, e.g. when ROM assignment, patch provided
8223 from Albert den Haan.
8225 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9248 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9249 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9250 type for bits was changed. It resulted in bit variables becoming

9268 A few small changes that speed up the peephole optimizer.
9272 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9274 Try to make the peephole optimizer smarter by maintaining
9275 an association between the assembly source code and the
9276 iCodes that originated them. Put this information to use
9277 with a new peephole rule condition "notVolatile" so that
9278 the rules can be aggressive yet still safe.
9283 * src/mcs51/peeph.def
9285 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9289 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9290 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9291 if the left or right operand symbols have the accuse flag set.
9293 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9295 Changed the type of the result of the ! (NOT) operator to char;
9296 previously it returned the same type as the source. This allows
9297 us to eliminate all the genFloatNot functions (all of its target
9298 implementations were very buggy) since !float can use the same

9310 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9311 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9312 during interrupts. Ensure WSAVE is located at a shared bank address.
9313 2. Fixed page selection in some places
9314 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9315 the registers name strings.
9316 4. Fixed "signed / unsigned compare" compiler warnings.
9317 5. The PIC port manages its own allocation of the general purpose
9318 registers, but makes no attempt to reuse them. As a result when
9319 compiling it soon runs out of general purpose registers. Some
9320 additional code was added to the files pcode.c and device.c to walk
9321 through the function call tree and rename the registers so that they
9331 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9332 genPlus() & genMinus() when the result is the same as left or right

9338 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9340 Made bitfield a distinct type from bit so that bitfields
9341 convert as per ANSI C and bits retain their traditional
9342 boolean style behaviour. Implemented bitfield support in
9350 * src/ds390/gen.c: bit v bitfield split
9351 * src/z80/gen.c: New support for bitfields
9352 * support/regression/tests/bitfields.c: reenabled z80,
9355 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9358 access to xdata mapped I/O devices.
9360 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9362 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9364 Cleaned up genPackBits and genUnpackBits and added two helper
9365 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9366 for literal assignments in genPackBits (thanks to Frieder for
9372 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9374 Fixed bug #748310 (pointer to function type mishandled when the
9375 function name is omitted). Also fixed a SIGSEGV when a function
9376 attribute (reentrant, etc) is used on a non-function or on a
9377 function but misplaced before the parameter list.
9379 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9381 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9404 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9406 Made the constant following the "interrupt" keyword optional. If
9407 omitted, the function will not automatically be given an entry
9408 in the interrupt vector table (similar to #pragma NOIV, but
9409 less syntacticly kludgy). The interrupt number is also now
9410 range checked. Also fixed a bug in the high order bit example

9431 unsigned, but are signed by default
9432 * src/SDCCval.c (constVal): rearranged
9433 * src/SDCCval.c (valMod): preliminary fix
9434 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9928 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9930 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9931 it can be defined with CFLAGS when running configure
9932 * src/SDCCmain.c: fixed compiling + linking with object files
9934 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9936 * configure.in: configure for pic16 port,
9937 added --disable-pic16-port
9938 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9939 * src/SDCCmain.c: linkOptions is changed to set *,
9940 added if/endif conditional macros to remove options help
9941 messages from optionsTable when a port is not configured, added
9942 support for the PIc16 port in the ports table, when executing
9943 the compiler with no port specified on command line, a default
9944 port is selected with the new macro DEFAULT_PORT which is
9945 defined in port.h, in setDefaultOptions() linkOptions is removed
9946 from initialization assignment, since now it is a set,
9947 parseCmdLine uses setParseWithComma for linkOptions, in
9948 linkEdit() linkOptions are accessed with new function indexSet()
9949 which returns the i'th item of a set variable. See SDCCset.c, in
9950 linkEdit() when calling buildCmdLine(), added linkOptions as
9951 last argument. Now users can pass arguments to gplink via the
9952 -Wl option, main() uses pic16glue() to glue up pic16 programs

9964 * src/pic16/glue.c: commented out some error producing lines
9965 * src/pic16/main.c: __config directives are commented out to stop
9966 gpasm complaining and test the linkage with gplink, _linkCmd and
9967 _asmCmd changed to be more gplink and gpasm friendly
9968 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9969 produced an error when parsed, peep rule 12 is added to utilize
9970 movff, but it is commented out since the pCode does not support
9971 yet a command with 2 address arguments
9973 2003-05-18 <johan AT balder>

10000 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
10002 2003-05-11 Borut Razem <borut.razem AT siol.net>
10004 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10005 the path of bin directory, so that PATH is the only env. variable, which has to be set
10006 in case of standard installation.

11023 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11024 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11031 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11033 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11034 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11036 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11038 * in /sdcc/as/mcs51/ changed these files in order to create an
11039 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11040 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11041 following files to include the previous two files: aslink.dsp,
11042 Makefile.aslink, Makefile.bcc, and Makefile.in.
11044 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11045 .adb instead of .cdb
11047 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11049 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11050 value from option --iram-size.
11052 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11054 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11057 2002-09-18 <wiml AT hhhh.org>
11059 * SDCClrange.h: exposed setFromRange() and setToRange()
11060 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11061 packRegsForAccUse() (bug 542397)
11062 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11063 multiple times and emitting the fetch operations more than once
11064 added aopGetUsesAcc() function to allow binary operators to
11065 fetch their operands in the correct order; made genMinus() emit
11066 compact code for X = LITERAL - Y
11068 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11069 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11070 sprintf() in line 1267.
11072 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11073 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11076 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11077 Changes to aslink (All the changes are marked with 'JCF'):
11079 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11082 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11083 area BSEG. Also moves, if possible, the DATA area down into the internal
11084 ram so more space is available.
11086 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11089 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11090 not bytes. Function summary() which creates a memory usage summary
11091 file with extension .mem. Reports of overlaping stack and small stack
11092 size. If the space for the stack is less than 16 bytes aslink trows a
11095 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11096 the 8051. Option 'y' for memory summary output file.
11098 Changes to sdcc (All the changes are marked with 'JCF'):
11100 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11102 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11103 overlaying area for it (uses RegBankUsed[4]).
11105 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11106 bank zero as used by default. By default aslink locates the stack
11107 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11108 the creation of the .mem file. Delegates the allocation of data area
11109 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11110 the begining of the stack area to aslink.
11112 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11113 glue() in SDCCglue.c creates an area for it.
11115 2002-09-03 Borut Razem <borut.razem AT siol.net>
11116 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11117 sdcc/src/pic/glue.c:
11118 introduced atexit() handler for teporay files removal in case of
11119 errors, assertions, ...
11121 2002-08-29 Borut Razem <borut.razem AT siol.net>
11122 * sdcc/support/cpp2/auto-host_vc_in.h:
11123 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11124 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11125 Maybe there is a similar problem with BORLANDC? It should be checked!
11127 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11128 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11129 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11130 was not executed, and the compiler (cl) launched a warning:
11131 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11133 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11134 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11136 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11137 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11139 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11140 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11141 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11142 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11143 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11144 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11145 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11146 - added Release configuration in VS projects
11147 - review of compiler an linker options
11148 - VC .exe files are generated in bin_vc directory, not to interfere
11149 with binaries generated from other projects (cygwin, mingw, bcc ...)
11151 * sdcc/src/yacc.dsp: added
11153 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11154 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11155 and insert the version number definitions from .version
11157 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11159 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11160 added - genarate auto-host.h using auto-host_vc_in.h as template
11163 removed from CVS, generated automatically
11165 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11166 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11168 2002-08-11 Borut Razem <borut.razem AT siol.net>
11169 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11171 2002-08-10 Borut Razem <borut.razem AT siol.net>
11172 * src/SDCCmain.c (main):
11173 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11174 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11175 The consequence was that some temporary files were not removed.
11178 unification of code in functions tempfilename() and tempfile():
11179 function tempnam() is defined in Visual Studio 6.0 and .NET
11181 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11183 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11184 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11185 - removed compiler command line option /WX: Treats all warnings as errors
11186 - update a list of source files, included into the project
11188 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11189 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11190 changed project type to Generic Project so that can be correcly converted to VS.NET project

11202 added newline in the def file to keep MSC compiler satisfied
11204 * sdcc/src/z80/gen.c:
11205 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11206 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11207 - solved MSC error in function aopDump()
11209 * sdcc_vc.h: define PREFIX as "\\sdcc"

11387 Previous fix was not good. basic blocks that have "break" or "return" are
11388 not really partof a loop , but live ranges used in these blocks should
