1177 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1179 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1180 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1182 One basic decision: e.g. src/clean.mk includes further files. In order
1183 to make this work there are two solutions:
1184 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1185 run configure on them. This way they can use
1186 'include $(srcdir)/port-clean.mk'
1187 - always include clean.mk by the Makefile at the same level. To avoid
1188 that `make clean` tries to include and build Makefile.dep the
1189 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1190 implemented, because now even `make uninstall` doesn't create
1191 Makefile.in. clean.mk could be eliminated by pasting it in
1194 * debugger/mcs51/Makefile.in: build own objects from library sources
1195 (SLIB, SDCC) in current directory
1197 * configure, configure.in: renamed --disable-device-lib-build in
1198 --disable-device-lib; added --enable-doc, the required tools are
1199 searched by configure; added result message; the toolchain for the
1200 belonging ports are now only built, if the port is enabled.
1202 * support/regression/*: all output is written in directory gen, because
1203 the fwk and ports directories don't livet in the build tree using vpath
1205 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1206 --disable-device-lib, added --enable-doc, added section VPATH
1208 * sim/ucsim/configure.in,
1209 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1210 z80 are enabled by default
1212 2006-04-24 Raphael Neider <rneider AT web.de>
1214 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1215 to config word, "pic14_"-prefixed some extern functions
1216 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1217 config word has been found
1218 * src/pic/device.h: added prototypes
1219 * src/pic/pcode.c: added "pic14_"-prefix where needed
1220 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1222 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1224 (pic14emitRegularMap): ignore config words,
1225 (pic14createInterruptVect): moved generating __config directives away
1226 (picglue): have __config directives emitted
1228 2006-04-24 Borut Razem <borut.razem AT siol.net>

1236 fixes #1469504 and #1474602,
1237 (pCodeRegOptimizeRegUsage): fixed typo in comment

1483 implemented patch 1120823 Thanks to Willy De la Court (normal
1484 interrupts need an interrupt number now if they are made critical),
1485 and enabled nesting of critical functions though not for gbz80
1486 (genCritical, genEndCritical): added functions
1487 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1488 * src/z80/mappings.i: added "ei" to all mappings

1500 the left operand is shorter than the result (c* = lit-c* + int),
1502 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1505 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1507 * src/.version: increased version number to 2.5.5
1508 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1509 linking is done manually in pic16 port's _linkEdit,
1510 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1511 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1512 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1513 allocate asmop as AOP_ACC,
1514 (aopForRemat): added parameter 'bool result' in function declaration,
1515 (pic16_aopGet): return AOP_ACC when accessing WREG,
1516 (pic16_popGetTempReg): minor modification,

1527 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1528 call to allocReg, not by manually allocating a new one,
1529 (pic16_assignRegisters): now before going through the register
1530 allocating functions mark all registers as free. This eliminates some
1531 side effects resulting from peephole parser done earlier in the backbone
1533 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1591 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1592 which dumps before the function entry point a data byte which represents
1593 the number of the local variables used by the specified function, added
1594 'xinst' for initial support for Extended Instruction Support,
1595 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1596 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1597 port->fun_prefix anymore (may change later),
1598 (genFunction, genEndFunction): do not store/restore local registers for
1599 _main (this should take care the --main-return command line option in
1601 (genOr): removed some legacy pic-port instructions,
1602 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1603 performing operations with SFR's causes data to be written more than
1604 once to each SFR. Perhaps SFRs should be handled in special cases...
1605 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1607 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1608 into account for stack starting position,

1610 --extended or -y for Extended Instruction Support,
1611 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1612 (deassignLRs): *** perhaps the most important change, old 'for' code
1613 (commented out for reference), didn't account for some registers which
1614 were left marked 'not free' after a pointer operation. The change
1615 reduces register usage a lot in some cases
1617 2006-03-04 Borut Razem <borut.razem AT siol.net>

3879 if condition == CARRY)
3880 * (genCmp): adapted to new genSkipc semantics
3881 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3882 on rIfx (genCmp was broken)
3884 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3886 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3887 * src/z80/main.c (_keywords[]),
3888 * src/SDCCglobal.h (struct options),
3890 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3891 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3892 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3893 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3894 always available in leading double underscore form. The C99 support is
3895 mostly missing, but it's a start.
3896 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3897 reserved identifier "__data".
3899 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3901 * src/mcs51/peeph.def: fixed bug 1170013

3909 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3912 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3914 * src/port.h (struct PORT),

3943 immedDom() returning wrong block; probably fixes bug #1160833)
3945 2005-03-20 Borut Razem <borut.razem AT siol.net>
3947 * support/scripts/inc2h.pl: WIN32 port
3949 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3951 * device/lib/makefile.in: added abs.c and labs.c
3953 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3955 * device/include/stdint.h: added
3956 * device/lib/abs.c: added
3957 * device/lib/labs.c: added
3958 * device/include/stdlib.h: added abs() and labs() prototypes

3973 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3975 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3977 * device/lib/printf_large.c: removed inline assembly for portability and
3978 readability. Use printf_fast if speed or size are more important.
3979 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3980 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3982 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3984 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3985 prevent compiler warning
3987 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3989 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3990 moved to level 0 and declared as static. Also they are explicit
3991 placed in access bank. This was necessery because some times they
3992 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3993 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3994 optimizations. Currently only compare to unsigned char is implemented,
3995 * src/pic16/gen.c: added fReturnIdx array,
3996 * (struct resolvedIfx) is moved to gen.h and made public,
3997 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3998 * (aopForSym): added an optimization to directly store in stack of
3999 the operand of a SEND iCode,
4000 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4001 but as registers instead (AOP_REG) using the fReturnIdx array,
4002 * (pic16_freeAsmop): remove the freed register from the
4003 _G.sregsAlloc field,
4004 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4005 a compare of 'WREG',
4006 * (pic16_popGetTempRegCond): changed function prototype, now
4007 function takes also a bitVector argument v which holds the current
4008 set of registers that are allocated for stack access by aopForSym,
4009 registers allocated in aopForSym for accessing stack symbols are not
4010 any more part of the functions usedRegs field,
4011 * (genCall): some times aopOp is called for a stack variable to be
4012 send, aopForSym might perform the push, if this is true make sure
4013 that genCall doesn't push the variable twice by testing _G.resDirect,
4014 * (genFunction): changed testing for unspecified interrupt number
4015 from 256 to INTNO_UNSPEC,
4016 * modified selection scheme of frame pointer generation. Previously
4017 if function did use local registers a frame pointer was generated,
4018 now a frame pointer is generated only if function has arguments
4019 (that need PLUSW2 register access), or has stack arguments, or the
4020 compiler is not instructed to omit the frame pointer,
4021 * (genEndFunction): before restoring local registers that were saved
4022 in the function preamble, also restore the registers that *might*
4023 have been allocated for stack access,
4024 * (genRet): removed some old comments,
4025 * (genCmp, the active (RN's) version): added a call to the
4026 pic16_genCmp_special function to perform the compare with a more
4027 robust and optimized way,
4028 * (genInline): a feature has been added in inline code generation,
4029 which allows a wildcard variable substitution when writing inline
4030 assembly. Code is incomplete and experimental therefore undocumented,
4031 * (genCast): changed order of aopOp for result and right to allow
4032 aopForSym to directly load the result if possible,
4033 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4034 perform an optimized compare on some selected special occasions,
4035 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4036 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4037 generate an IVT any more,
4038 * src/pic16/main.c (pic16_optionsTable): added command line option
4040 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4041 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4043 * src/pic16/NOTES: Raphael Neider added in list of active developers
4044 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4045 jumptable_end to prevent bug #,
4046 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4047 inCond and outCond fields,
4048 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4049 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4050 turn off register spilling,
4051 * (packRegsForOneUse): synced with other ports' versions although it
4052 is not used currently,
4053 * (pic16_packRegisters): added an optimization while reading
4054 structure bitfields, some registers may be saved (malloc code is
4055 decreased by 80 bytes)
4057 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4059 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4060 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4061 this can be optimized more?
4063 2005-03-10 Raphael Neider <rneider AT web.de>
4065 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4066 genNearPointerGet): (hopefully) fixed access to bitfields via
4067 pointers (p->bitN = x; and x = p->bitN; failed)
4069 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4255 of (byte sized) temporaries (assign them to WREG for now)
4256 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4257 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4258 this might fix SIGSEGVs on MinGW...
4259 * src/SDCCopt.c (killDeadCode): restored original behaviour
4260 (volatile operands might get thrown away though)
4262 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4264 * src/pic16/gen.c: fixed bug #1106975,

4301 when calling assembler to reflect memory model used, also define
4302 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4303 reflect stack model used,

4739 * added libc directory. The current version of LibC contains string
4740 functions, ctype functions and macros and some functions of the
4741 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4742 be extensively tested in the future. Standard disclaimer here.
4743 Library is not automatically build yet. But one can build it by
4744 invoking 'make' inside the libc directory.
4745 * added ADC library under libio. Preliminary version yet.
4747 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4755 * (pic16_storeForReturn): optimized return of 0,
4756 * (genCmp): experimental code for new genCmp which uses PIC18's
4757 special compare&skip instructions. Initial tests fail some times
4758 with variables grater than 1 byte in size, so new code is disabled,
4759 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4761 * (genCast): began a fix to optimize the casting of a bit to another
4762 bit, now assigning a bitfield to another bitfield will fail, sorry,
4763 * src/pic16/main.c: disabled the use of lr-support feature,
4764 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4767 bits with offset (case PO_GPR_BIT),
4768 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4770 * (isBankInstruction): modified to return 0 for no banking instruction,
4771 and 1 for banking instruction,
4772 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4773 caused stop processing pCodes after a inline assembly block,
4774 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4775 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4776 registers when it shouldn't,
4777 * src/pic16/ralloc.c (allocReg): add preliminary support for
4778 supporting a limited set of temporary registers,

7785 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7787 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7788 loaded with the linker search paths (-L arguments) and the libraries
7789 to be linked with the current source (-l arguments). Changes
7790 currently will affect only the pic16 port.
7791 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7792 include path the port specific paths and port specific libraries,
7793 * gplink command now contains the $3 argument,
7794 * src/pic16/device.h,
7795 * src/pic16/device.c,: structure PIC_device is made public and
7796 renamed to PIC16_device, the same for variable Pics which is renamed

7811 Documenting changes from previous commits.
7812 * configure.in (version 1.56),
7813 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7814 when generating output files to configure the pic16 library,
7815 but now I've commented it out, since gputils aren't installed in the
7816 SF compile farm, so library won't compile
7818 * device/lib/Makefile.in (version 1.56): initially I've added in
7819 target 'all' the prerequestive 'model-pic16' so it compiled the
7820 pic16 library, but now I've commented it out for the same reasons
7822 * added targets 'model-pic16' and 'objects-pic16' to compile the
7824 * added target 'port-specific-objects-pic16' to handle the
7825 generated libraries and copy them into the build/ directory
7826 * added target 'clean-intermediate-pic16' to clean intermediate
7827 files into pic16 directory
7828 * in target 'installdirs' added line to create directory pic16 in
7829 the installation path
7831 * device/include/Makefile.in (version 1.11): in target 'install'
7832 added lines to copy all header files to installation path,

7879 via literal number. The symbol is placed in the corresponding
7880 position of the data ram
7881 * (pic16_dump_section): relocatable and absolute uninitialized
7882 data are now emitted in sorted order to reduce section naming,
7883 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7884 weren't marked as being in the access bank,
7886 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7888 Added portion of GNU PIC Library under the directory
7889 device/include/pic16 and device/lib/pic16. These files
7890 contain the declarations of SFRs for the PIC18Fxx2 devices.

7921 all over. Telling LaTeX to be less strict with word spacing
7922 to better keep the right margin. Changed some notes about
7923 maintainance of the ports in section 3.2.1 - is it OK like this?
7925 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7965 * src/pic16/peeph.def: all peepholes with movff are commented out,
7966 because there is a problem in the pcode peep optimizer,
7967 * src/pic16/ralloc.c: the register allocator can now reuse local

8004 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8007 * src/z80/main.c: added missed needLinkerScript flags (more than
8008 one port structure defined in these file)
8009 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8060 include information about variables allocated to the overlay
8063 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8065 * as/mcs51/lkmain.c: Help about -Y option

8077 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8079 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8080 (default behaviour).
8082 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8084 A python script to validate compiler diagnostic messages. It can be
8085 used to verify that sdcc complains about bad c source code and
8086 gives a good location of the error.
8087 * support/valdiag/Makefile,
8088 * support/valdiag/valdiag.py,
8089 * support/valdiag/tests/*
8091 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8093 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8104 * src/common.h: added ifndef/define/endif macros
8105 around the header file.
8106 Bug reported from Jesus Calvino-Fraga
8108 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8110 * sdcc.spec: updated
8111 * device/include/Makefile.in: don't install CVS directories
8112 * device/lib/Makefile.in: added removal of CVS directories after install
8113 * doc/Makefile: fixed install, added local_icons
8114 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8115 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8116 * src/ds390/gen.c (genRightShift): fixed bug #870788
8117 * src/SDCCast.c (decorateType): fixed bug #870781
8119 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8121 PIC16 port related changes:
8122 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8123 added variable stackPos,
8125 * gen.c: genCall, assignResultValue: added support for
8126 pushing/retrieving function parameters to/from stack,
8127 genFunction,genEndFunction: setup stack frame for the
8129 genAddrOf: will be changed according to bug 863624
8131 * added files genutils.c and genutils.h which contain gen*
8132 debugged and optimised functions extracted from gen.c
8134 * glue.c: added variable 'externs' which holds extern symbols,
8135 pic16emitRegularMap: is modified to properly handle relocatable
8136 symbols under the new scheme,
8137 pic16createInterruptVect: is modified
8138 pic16printPublics: is modified to emit 'global' assembler directives,
8139 added pic16_printExterns to print extern symbols,
8140 pic16glue: initializes stack/frame pointer in the beginning of
8141 the assembly output. Temporary hack, will be corrected later,
8142 because gplink yet does not support stack and SDCC does not
8143 yet support a type of crt0.o object to create the final binary.
8145 * Removed many lines that contain 8051 legacy code.
8146 * The code is finally placed under a 'code' directive.
8147 * Added port specific options.
8149 * _process_pragma: simplified since now we do not need *special*
8150 include file to define SFR registers. But a separate header
8151 will be needed. This will be developed later.
8152 * _pic16_parseOptions: added, parses port specific options:
8153 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8154 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8155 --preplace-udata-with=
8157 * _pic16_setDefaultOptions: modified to initialize section names,
8158 but hack is temporarly out of order since it needs improvement.
8159 * _pic16_genAssemblerPreamble: configuration words are emitted by
8160 their address instead of their name. This part is incomplete and
8161 supports only the 18Fxx2 devices. Other devices will emit an error
8162 during assembly since they do not contain the same set of config
8164 * _pic16_genIVT: is modified,
8166 * pcode.c: added definitions for some hardware registers that are needed
8168 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8169 All PCI entries are updated. Now LFSR is supported.
8170 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8171 * added pic16_newpCodeOpLit2 to support instructions with
8172 two literal arguments
8173 * pic16_pCode2str: corrected code that emits assembler instructions
8174 with two literal operands and those that have an access bit modifier
8175 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8176 this fixes a bug which caused some labels to be lost, when an
8177 assembler directive was added, i.e. banksel,
8178 * pic16_FixRegisterBanking: improved logic that causes the insertion
8180 * InlineFunction: functions that are called once, are not any more
8181 inlined. This can be a port option in the future,
8183 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8185 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8186 hold the corresponding uninitialized symbols,
8187 * pic16_allocProcessorRegister: registers have explicit marked the
8189 * pic16_allocInternalRegister: registers are explicit marked as
8191 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8192 processing list, so bit registers were lost,
8195 * ralloc.h: added field 'accessBank' and original symbol operand
8196 in register definition,
8197 * removed the field isMapped from register definition,
8199 ** Several functions have been removed from various sources:
8200 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8201 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8202 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8203 pic16_assignRelocatableRegisters
8205 ** others have been introduced:
8206 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8207 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8209 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8211 * support/scripts/inc2h.pl: changed definition of BIT_AT
8212 to emit 'sbit at' instead of 'bit at'. This was a request.
8214 PIC16 port related preliminary changes:
8215 * gen.c: prefixed function popRegFromString with
8216 pic16_ and all references to it corrected
8217 * pcode.c: all pic16_pc_* hardware registers prefixed
8218 with underscore (_),
8219 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8220 * ralloc.c: newReg(): when register is REG_SFR then
8221 set address to rIdx,
8222 pic16_allocProcessorRegister(): marks register wasUsed=0
8223 pic16_writeUsedRegs(): added a call to assign processor
8224 registers via pic16_assignFixedRegisters
8226 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8228 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8229 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8230 variables in unused register banks. Also the SSEG is placed
8231 wherever there is enough space for it, and IDATA can be anywhere
8232 in internal RAM. For now compile using -Wl-Y[stack_size].
8233 The mem file is different for this option as well, since it
8234 makes no sense of talking about DSEG lenght.
8236 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8238 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8239 in certain cases, e.g. when ROM assignment, patch provided
8240 from Albert den Haan.
8242 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9249 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9250 If they pop r0/r1 they must be called in the opposite order than aopOp().

9265 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9266 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

9285 A few small changes that speed up the peephole optimizer.
9289 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9291 Try to make the peephole optimizer smarter by maintaining
9292 an association between the assembly source code and the
9293 iCodes that originated them. Put this information to use
9294 with a new peephole rule condition "notVolatile" so that
9295 the rules can be aggressive yet still safe.
9300 * src/mcs51/peeph.def
9302 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9306 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9307 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9308 if the left or right operand symbols have the accuse flag set.
9310 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9312 Changed the type of the result of the ! (NOT) operator to char;
9313 previously it returned the same type as the source. This allows
9314 us to eliminate all the genFloatNot functions (all of its target
9315 implementations were very buggy) since !float can use the same
9318 * src/SDCCicode.c (ast2iCode): ! returns char
9319 * src/mcs51/gen.c (genNot, genNotFloat),
9320 * src/ds390/gen.c (genNot, genNotFloat),
9321 * src/z80/gen.c (genNot, genNotFloat),
9322 * src/pic/gen.c (genNot, genNotFloat),

9329 during interrupts. Ensure WSAVE is located at a shared bank address.
9330 2. Fixed page selection in some places
9331 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9332 the registers name strings.
9333 4. Fixed "signed / unsigned compare" compiler warnings.
9334 5. The PIC port manages its own allocation of the general purpose
9335 registers, but makes no attempt to reuse them. As a result when
9336 compiling it soon runs out of general purpose registers. Some
9337 additional code was added to the files pcode.c and device.c to walk
9338 through the function call tree and rename the registers so that they
9348 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9355 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9357 Made bitfield a distinct type from bit so that bitfields
9358 convert as per ANSI C and bits retain their traditional
9359 boolean style behaviour. Implemented bitfield support in
9367 * src/ds390/gen.c: bit v bitfield split
9368 * src/z80/gen.c: New support for bitfields
9369 * support/regression/tests/bitfields.c: reenabled z80,
9372 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9374 Rules 246.x, 247.x relate to bitfields, the others speed up
9375 access to xdata mapped I/O devices.
9377 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9379 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9381 Cleaned up genPackBits and genUnpackBits and added two helper
9382 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9383 for literal assignments in genPackBits (thanks to Frieder for
9389 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9391 Fixed bug #748310 (pointer to function type mishandled when the
9392 function name is omitted). Also fixed a SIGSEGV when a function
9393 attribute (reentrant, etc) is used on a non-function or on a
9394 function but misplaced before the parameter list.

9421 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9423 Made the constant following the "interrupt" keyword optional. If
9424 omitted, the function will not automatically be given an entry
9425 in the interrupt vector table (similar to #pragma NOIV, but
9426 less syntacticly kludgy). The interrupt number is also now
9427 range checked. Also fixed a bug in the high order bit example

9948 it can be defined with CFLAGS when running configure
9949 * src/SDCCmain.c: fixed compiling + linking with object files
9951 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9954 added --disable-pic16-port
9955 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9956 * src/SDCCmain.c: linkOptions is changed to set *,
9957 added if/endif conditional macros to remove options help
9958 messages from optionsTable when a port is not configured, added
9959 support for the PIc16 port in the ports table, when executing
9960 the compiler with no port specified on command line, a default
9961 port is selected with the new macro DEFAULT_PORT which is
9962 defined in port.h, in setDefaultOptions() linkOptions is removed
9963 from initialization assignment, since now it is a set,
9964 parseCmdLine uses setParseWithComma for linkOptions, in
9965 linkEdit() linkOptions are accessed with new function indexSet()
9966 which returns the i'th item of a set variable. See SDCCset.c, in
9967 linkEdit() when calling buildCmdLine(), added linkOptions as
9968 last argument. Now users can pass arguments to gplink via the
9969 -Wl option, main() uses pic16glue() to glue up pic16 programs

9981 * src/pic16/glue.c: commented out some error producing lines
9982 * src/pic16/main.c: __config directives are commented out to stop
9983 gpasm complaining and test the linkage with gplink, _linkCmd and
9984 _asmCmd changed to be more gplink and gpasm friendly
9985 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9986 produced an error when parsed, peep rule 12 is added to utilize
9987 movff, but it is commented out since the pCode does not support
9988 yet a command with 2 address arguments
9990 2003-05-18 <johan AT balder>
9992 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11053 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11055 * in /sdcc/as/mcs51/ changed these files in order to create an
11056 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11057 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11058 following files to include the previous two files: aslink.dsp,
11059 Makefile.aslink, Makefile.bcc, and Makefile.in.
11061 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11062 .adb instead of .cdb
11064 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11066 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11067 value from option --iram-size.
11069 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11071 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11074 2002-09-18 <wiml AT hhhh.org>
11076 * SDCClrange.h: exposed setFromRange() and setToRange()
11077 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11078 packRegsForAccUse() (bug 542397)
11079 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11080 multiple times and emitting the fetch operations more than once
11081 added aopGetUsesAcc() function to allow binary operators to
11082 fetch their operands in the correct order; made genMinus() emit
11083 compact code for X = LITERAL - Y
11085 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11086 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11087 sprintf() in line 1267.
11089 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11090 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11093 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11094 Changes to aslink (All the changes are marked with 'JCF'):
11096 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11099 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11100 area BSEG. Also moves, if possible, the DATA area down into the internal
11101 ram so more space is available.
11103 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11106 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11107 not bytes. Function summary() which creates a memory usage summary
11108 file with extension .mem. Reports of overlaping stack and small stack
11109 size. If the space for the stack is less than 16 bytes aslink trows a
11112 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11113 the 8051. Option 'y' for memory summary output file.
11115 Changes to sdcc (All the changes are marked with 'JCF'):
11117 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11119 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11120 overlaying area for it (uses RegBankUsed[4]).
11122 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11123 bank zero as used by default. By default aslink locates the stack
11124 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11125 the creation of the .mem file. Delegates the allocation of data area
11126 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11127 the begining of the stack area to aslink.
11129 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11130 glue() in SDCCglue.c creates an area for it.
11132 2002-09-03 Borut Razem <borut.razem AT siol.net>
11133 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11134 sdcc/src/pic/glue.c:
11135 introduced atexit() handler for teporay files removal in case of
11136 errors, assertions, ...
11138 2002-08-29 Borut Razem <borut.razem AT siol.net>
11139 * sdcc/support/cpp2/auto-host_vc_in.h:
11140 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11141 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11142 Maybe there is a similar problem with BORLANDC? It should be checked!
11144 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11145 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11146 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11147 was not executed, and the compiler (cl) launched a warning:
11148 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11150 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11188 2002-08-10 Borut Razem <borut.razem AT siol.net>
11189 * src/SDCCmain.c (main):
11190 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11191 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11192 The consequence was that some temporary files were not removed.
11195 unification of code in functions tempfilename() and tempfile():
11196 function tempnam() is defined in Visual Studio 6.0 and .NET
11198 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11200 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11201 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11202 - removed compiler command line option /WX: Treats all warnings as errors
11203 - update a list of source files, included into the project
11205 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11206 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11207 changed project type to Generic Project so that can be correcly converted to VS.NET project
11209 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11211 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

11215 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11216 added return 0 statements after assert() to make compiler happy
11218 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11219 added newline in the def file to keep MSC compiler satisfied
11221 * sdcc/src/z80/gen.c:
11222 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11223 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11224 - solved MSC error in function aopDump()
11226 * sdcc_vc.h: define PREFIX as "\\sdcc"
11228 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11401 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11403 * sdcc/src/SDCCloop.c:
11404 Previous fix was not good. basic blocks that have "break" or "return" are
11405 not really partof a loop , but live ranges used in these blocks should
