134 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
136 Enabled VPATH feature: changed nearly all Makefiles (149 files).
137 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
139 One basic decision: e.g. src/clean.mk includes further files. In order
140 to make this work there are two solutions:
141 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
142 run configure on them. This way they can use
143 'include $(srcdir)/port-clean.mk'
144 - always include clean.mk by the Makefile at the same level. To avoid
145 that `make clean` tries to include and build Makefile.dep the
146 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
147 implemented, because now even `make uninstall` doesn't create
148 Makefile.in. clean.mk could be eliminated by pasting it in
151 * debugger/mcs51/Makefile.in: build own objects from library sources
152 (SLIB, SDCC) in current directory
154 * configure, configure.in: renamed --disable-device-lib-build in
155 --disable-device-lib; added --enable-doc, the required tools are
156 searched by configure; added result message; the toolchain for the
157 belonging ports are now only built, if the port is enabled.
159 * support/regression/*: all output is written in directory gen, because
160 the fwk and ports directories don't livet in the build tree using vpath
162 * doc/sdccman.lyx: renamed --disable-device-lib-build to
163 --disable-device-lib, added --enable-doc, added section VPATH
165 * sim/ucsim/configure.in,
166 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
167 z80 are enabled by default
169 2006-04-24 Raphael Neider <rneider AT web.de>
171 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
172 to config word, "pic14_"-prefixed some extern functions
173 (pic14_emitConfigWord): emit __config directive(s) if assignment to
174 config word has been found
175 * src/pic/device.h: added prototypes
176 * src/pic/pcode.c: added "pic14_"-prefix where needed

179 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

471 (aopForRemat): added parameter 'bool result' in function declaration,
472 (pic16_aopGet): return AOP_ACC when accessing WREG,

485 call to allocReg, not by manually allocating a new one,
486 (pic16_assignRegisters): now before going through the register
487 allocating functions mark all registers as free. This eliminates some
488 side effects resulting from peephole parser done earlier in the backbone

548 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
549 which dumps before the function entry point a data byte which represents
550 the number of the local variables used by the specified function, added
551 'xinst' for initial support for Extended Instruction Support,
552 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
553 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
554 port->fun_prefix anymore (may change later),

558 (genOr): removed some legacy pic-port instructions,
559 * src/pic16/genarith.c (genAddLit): re-enabled old code because
560 performing operations with SFR's causes data to be written more than
561 once to each SFR. Perhaps SFRs should be handled in special cases...
562 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

569 (deassignLRs): *** perhaps the most important change, old 'for' code
570 (commented out for reference), didn't account for some registers which
571 were left marked 'not free' after a pointer operation. The change
572 reduces register usage a lot in some cases

2930 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2932 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2934 * device/lib/printf_large.c: removed inline assembly for portability and
2935 readability. Use printf_fast if speed or size are more important.
2936 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2937 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2939 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2941 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2942 prevent compiler warning
2944 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2946 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2947 moved to level 0 and declared as static. Also they are explicit
2948 placed in access bank. This was necessery because some times they
2949 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2950 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2951 optimizations. Currently only compare to unsigned char is implemented,
2952 * src/pic16/gen.c: added fReturnIdx array,
2953 * (struct resolvedIfx) is moved to gen.h and made public,
2954 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2955 * (aopForSym): added an optimization to directly store in stack of
2956 the operand of a SEND iCode,
2957 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2958 but as registers instead (AOP_REG) using the fReturnIdx array,
2959 * (pic16_freeAsmop): remove the freed register from the
2960 _G.sregsAlloc field,
2961 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2962 a compare of 'WREG',
2963 * (pic16_popGetTempRegCond): changed function prototype, now
2964 function takes also a bitVector argument v which holds the current
2965 set of registers that are allocated for stack access by aopForSym,
2966 registers allocated in aopForSym for accessing stack symbols are not
2967 any more part of the functions usedRegs field,
2968 * (genCall): some times aopOp is called for a stack variable to be
2969 send, aopForSym might perform the push, if this is true make sure
2970 that genCall doesn't push the variable twice by testing _G.resDirect,
2971 * (genFunction): changed testing for unspecified interrupt number
2972 from 256 to INTNO_UNSPEC,
2973 * modified selection scheme of frame pointer generation. Previously
2974 if function did use local registers a frame pointer was generated,
2975 now a frame pointer is generated only if function has arguments
2976 (that need PLUSW2 register access), or has stack arguments, or the
2977 compiler is not instructed to omit the frame pointer,
2978 * (genEndFunction): before restoring local registers that were saved
2979 in the function preamble, also restore the registers that *might*
2980 have been allocated for stack access,
2981 * (genRet): removed some old comments,
2982 * (genCmp, the active (RN's) version): added a call to the
2983 pic16_genCmp_special function to perform the compare with a more
2984 robust and optimized way,
2985 * (genInline): a feature has been added in inline code generation,
2986 which allows a wildcard variable substitution when writing inline
2987 assembly. Code is incomplete and experimental therefore undocumented,
2988 * (genCast): changed order of aopOp for result and right to allow
2989 aopForSym to directly load the result if possible,
2990 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2991 perform an optimized compare on some selected special occasions,
2992 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2993 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2994 generate an IVT any more,
2995 * src/pic16/main.c (pic16_optionsTable): added command line option
2997 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2998 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3000 * src/pic16/NOTES: Raphael Neider added in list of active developers
3001 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3002 jumptable_end to prevent bug #,
3003 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3004 inCond and outCond fields,
3005 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3006 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3007 turn off register spilling,
3008 * (packRegsForOneUse): synced with other ports' versions although it
3009 is not used currently,
3010 * (pic16_packRegisters): added an optimization while reading
3011 structure bitfields, some registers may be saved (malloc code is
3012 decreased by 80 bytes)
3014 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3016 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3017 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3018 this can be optimized more?
3020 2005-03-10 Raphael Neider <rneider AT web.de>
3022 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3023 genNearPointerGet): (hopefully) fixed access to bitfields via
3024 pointers (p->bitN = x; and x = p->bitN; failed)

3658 Adding support for replacing ljmps with sjmps in jumptables
3659 generated for switch statements. For now you need to set the
3660 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3661 Now 4 algorithms for mcs51 jumptable generation are used:
3662 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3663 addresses loaded pc-relative for up to 112 cases and stack-pushing
3664 target addresses loaded with offset from dptr for up to 256 cases.

3694 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3696 * added libc directory. The current version of LibC contains string
3697 functions, ctype functions and macros and some functions of the
3698 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3699 be extensively tested in the future. Standard disclaimer here.
3700 Library is not automatically build yet. But one can build it by
3701 invoking 'make' inside the libc directory.

3712 * (pic16_storeForReturn): optimized return of 0,
3713 * (genCmp): experimental code for new genCmp which uses PIC18's
3714 special compare&skip instructions. Initial tests fail some times
3715 with variables grater than 1 byte in size, so new code is disabled,
3716 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3718 * (genCast): began a fix to optimize the casting of a bit to another
3719 bit, now assigning a bitfield to another bitfield will fail, sorry,

3728 and 1 for banking instruction,
3729 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3730 caused stop processing pCodes after a inline assembly block,
3731 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3733 registers when it shouldn't,
3734 * src/pic16/ralloc.c (allocReg): add preliminary support for
3735 supporting a limited set of temporary registers,
3737 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3743 (genFunction): optimize RECEIVE iCodes in reentrant functions
3745 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6745 loaded with the linker search paths (-L arguments) and the libraries
6746 to be linked with the current source (-l arguments). Changes
6747 currently will affect only the pic16 port.
6748 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6749 include path the port specific paths and port specific libraries,
6750 * gplink command now contains the $3 argument,
6751 * src/pic16/device.h,

6768 Documenting changes from previous commits.
6769 * configure.in (version 1.56),
6770 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6771 when generating output files to configure the pic16 library,
6772 but now I've commented it out, since gputils aren't installed in the
6773 SF compile farm, so library won't compile
6775 * device/lib/Makefile.in (version 1.56): initially I've added in
6776 target 'all' the prerequestive 'model-pic16' so it compiled the
6777 pic16 library, but now I've commented it out for the same reasons
6779 * added targets 'model-pic16' and 'objects-pic16' to compile the
6781 * added target 'port-specific-objects-pic16' to handle the
6782 generated libraries and copy them into the build/ directory
6783 * added target 'clean-intermediate-pic16' to clean intermediate
6784 files into pic16 directory
6785 * in target 'installdirs' added line to create directory pic16 in

6789 added lines to copy all header files to installation path,
6790 * in target 'installdirs' added line create directory for pic16
6791 headers in the installation path

7039 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7041 A python script to validate compiler diagnostic messages. It can be
7042 used to verify that sdcc complains about bad c source code and
7043 gives a good location of the error.
7044 * support/valdiag/Makefile,
7045 * support/valdiag/valdiag.py,
7046 * support/valdiag/tests/*
7048 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7050 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7051 * src/SDCCsymt.c (newEnumType),
7053 * support/Util/SDCCerr.c,
7054 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7056 * support/regression/tests/enum.c: added test for enum values that
7057 require at least 2 bytes of storage.
7059 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7061 * src/common.h: added ifndef/define/endif macros
7062 around the header file.
7063 Bug reported from Jesus Calvino-Fraga
7065 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7067 * sdcc.spec: updated
7068 * device/include/Makefile.in: don't install CVS directories
7069 * device/lib/Makefile.in: added removal of CVS directories after install
7070 * doc/Makefile: fixed install, added local_icons
7071 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7072 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7073 * src/ds390/gen.c (genRightShift): fixed bug #870788
7074 * src/SDCCast.c (decorateType): fixed bug #870781
7076 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7078 PIC16 port related changes:
7079 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7080 added variable stackPos,
7082 * gen.c: genCall, assignResultValue: added support for
7083 pushing/retrieving function parameters to/from stack,
7084 genFunction,genEndFunction: setup stack frame for the
7086 genAddrOf: will be changed according to bug 863624
7088 * added files genutils.c and genutils.h which contain gen*
7089 debugged and optimised functions extracted from gen.c
7091 * glue.c: added variable 'externs' which holds extern symbols,
7092 pic16emitRegularMap: is modified to properly handle relocatable
7093 symbols under the new scheme,
7094 pic16createInterruptVect: is modified
7095 pic16printPublics: is modified to emit 'global' assembler directives,
7096 added pic16_printExterns to print extern symbols,
7097 pic16glue: initializes stack/frame pointer in the beginning of
7098 the assembly output. Temporary hack, will be corrected later,
7099 because gplink yet does not support stack and SDCC does not
7100 yet support a type of crt0.o object to create the final binary.
7102 * Removed many lines that contain 8051 legacy code.
7103 * The code is finally placed under a 'code' directive.
7104 * Added port specific options.
7106 * _process_pragma: simplified since now we do not need *special*
7107 include file to define SFR registers. But a separate header
7108 will be needed. This will be developed later.
7109 * _pic16_parseOptions: added, parses port specific options:
7110 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7111 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7112 --preplace-udata-with=
7114 * _pic16_setDefaultOptions: modified to initialize section names,
7115 but hack is temporarly out of order since it needs improvement.
7116 * _pic16_genAssemblerPreamble: configuration words are emitted by
7117 their address instead of their name. This part is incomplete and
7118 supports only the 18Fxx2 devices. Other devices will emit an error
7119 during assembly since they do not contain the same set of config
7121 * _pic16_genIVT: is modified,
7123 * pcode.c: added definitions for some hardware registers that are needed
7125 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7126 All PCI entries are updated. Now LFSR is supported.
7127 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7128 * added pic16_newpCodeOpLit2 to support instructions with
7129 two literal arguments
7130 * pic16_pCode2str: corrected code that emits assembler instructions
7131 with two literal operands and those that have an access bit modifier
7132 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7133 this fixes a bug which caused some labels to be lost, when an
7134 assembler directive was added, i.e. banksel,
7135 * pic16_FixRegisterBanking: improved logic that causes the insertion
7137 * InlineFunction: functions that are called once, are not any more
7138 inlined. This can be a port option in the future,
7140 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7142 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7143 hold the corresponding uninitialized symbols,
7144 * pic16_allocProcessorRegister: registers have explicit marked the
7146 * pic16_allocInternalRegister: registers are explicit marked as
7148 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7149 processing list, so bit registers were lost,
7152 * ralloc.h: added field 'accessBank' and original symbol operand
7153 in register definition,
7154 * removed the field isMapped from register definition,
7156 ** Several functions have been removed from various sources:
7157 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7158 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7159 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7160 pic16_assignRelocatableRegisters
7162 ** others have been introduced:
7163 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7164 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7166 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7168 * support/scripts/inc2h.pl: changed definition of BIT_AT
7169 to emit 'sbit at' instead of 'bit at'. This was a request.
7171 PIC16 port related preliminary changes:
7172 * gen.c: prefixed function popRegFromString with
7173 pic16_ and all references to it corrected
7174 * pcode.c: all pic16_pc_* hardware registers prefixed
7175 with underscore (_),
7176 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7177 * ralloc.c: newReg(): when register is REG_SFR then
7178 set address to rIdx,
7179 pic16_allocProcessorRegister(): marks register wasUsed=0
7180 pic16_writeUsedRegs(): added a call to assign processor
7181 registers via pic16_assignFixedRegisters
7183 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7185 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7186 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7187 variables in unused register banks. Also the SSEG is placed
7188 wherever there is enough space for it, and IDATA can be anywhere
7189 in internal RAM. For now compile using -Wl-Y[stack_size].
7190 The mem file is different for this option as well, since it
7191 makes no sense of talking about DSEG lenght.
7193 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7195 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7196 in certain cases, e.g. when ROM assignment, patch provided
7197 from Albert den Haan.
7199 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7342 * src/mcs51/peephole.def,
7343 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7355 multiply defined with mismatching "at" address.
7357 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7359 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

7438 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7440 * src/SDCCast.c (decorateType): disabled a transformation I added in
7441 revision 1.188 (access to fields of a structure at an absolute address);
7442 it breaks with bitfields, extern declarations, and gcse analysis.
7443 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7444 could be assigned through a pointer, so don't complain.
7445 * src/SDCCast.c (astErrors),
7447 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8085 support for standard C idiom of memory mapped variables; for
8086 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8087 to xdata int at 0x1234 tempvar = 1.
8088 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8089 provided by Akiya ISHIDA

8105 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8107 Fixed bug #621531 (const & volatile confusion in the type chain).
8108 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8109 refer to the const or volatile state of the pointer itself.

8200 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8201 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8202 fetching of the pointer
8203 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8204 copied from genNearPointerSet()
8205 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8206 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8207 If they pop r0/r1 they must be called in the opposite order than aopOp().
8208 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8209 (resp. --stack-auto), prepared for --xstack

8220 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8222 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8223 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8224 type for bits was changed. It resulted in bit variables becoming
8225 global, which is not permitted in PIC 14 assembly output.
8227 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8229 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8242 A few small changes that speed up the peephole optimizer.
8246 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8248 Try to make the peephole optimizer smarter by maintaining
8249 an association between the assembly source code and the
8250 iCodes that originated them. Put this information to use
8251 with a new peephole rule condition "notVolatile" so that
8252 the rules can be aggressive yet still safe.
8257 * src/mcs51/peeph.def
8259 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8263 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8264 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8265 if the left or right operand symbols have the accuse flag set.
8267 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8269 Changed the type of the result of the ! (NOT) operator to char;
8270 previously it returned the same type as the source. This allows
8271 us to eliminate all the genFloatNot functions (all of its target
8272 implementations were very buggy) since !float can use the same
8275 * src/SDCCicode.c (ast2iCode): ! returns char

8284 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8285 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8286 during interrupts. Ensure WSAVE is located at a shared bank address.
8287 2. Fixed page selection in some places
8288 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8289 the registers name strings.
8290 4. Fixed "signed / unsigned compare" compiler warnings.
8291 5. The PIC port manages its own allocation of the general purpose
8292 registers, but makes no attempt to reuse them. As a result when
8293 compiling it soon runs out of general purpose registers. Some
8294 additional code was added to the files pcode.c and device.c to walk
8295 through the function call tree and rename the registers so that they
8305 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8306 genPlus() & genMinus() when the result is the same as left or right

8312 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8314 Made bitfield a distinct type from bit so that bitfields
8315 convert as per ANSI C and bits retain their traditional
8316 boolean style behaviour. Implemented bitfield support in
8324 * src/ds390/gen.c: bit v bitfield split
8325 * src/z80/gen.c: New support for bitfields
8326 * support/regression/tests/bitfields.c: reenabled z80,
8329 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8331 Rules 246.x, 247.x relate to bitfields, the others speed up
8332 access to xdata mapped I/O devices.
8334 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8336 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8338 Cleaned up genPackBits and genUnpackBits and added two helper
8339 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8340 for literal assignments in genPackBits (thanks to Frieder for
8346 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8348 Fixed bug #748310 (pointer to function type mishandled when the
8349 function name is omitted). Also fixed a SIGSEGV when a function
8350 attribute (reentrant, etc) is used on a non-function or on a
8351 function but misplaced before the parameter list.
8353 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8355 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8356 * support/Util/SDCCerr.h,
8357 * support/Util/SDCCerr.c: Added func attr misuse error msg

8378 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8380 Made the constant following the "interrupt" keyword optional. If
8381 omitted, the function will not automatically be given an entry
8382 in the interrupt vector table (similar to #pragma NOIV, but
8383 less syntacticly kludgy). The interrupt number is also now
8384 range checked. Also fixed a bug in the high order bit example

8398 * src/SDCCicode.c (operandOperation): rewritten some ops
8399 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8400 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8402 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8403 be re-activated by defining REDUCE_LITERALS)
8404 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8405 unsigned, but are signed by default
8406 * src/SDCCval.c (constVal): rearranged
8407 * src/SDCCval.c (valMod): preliminary fix
8408 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8913 * src/SDCCmain.c: linkOptions is changed to set *,
8914 added if/endif conditional macros to remove options help
8915 messages from optionsTable when a port is not configured, added
8916 support for the PIc16 port in the ports table, when executing
8917 the compiler with no port specified on command line, a default
8918 port is selected with the new macro DEFAULT_PORT which is
8919 defined in port.h, in setDefaultOptions() linkOptions is removed
8920 from initialization assignment, since now it is a set,
8921 parseCmdLine uses setParseWithComma for linkOptions, in
8922 linkEdit() linkOptions are accessed with new function indexSet()
8923 which returns the i'th item of a set variable. See SDCCset.c, in
8924 linkEdit() when calling buildCmdLine(), added linkOptions as
8925 last argument. Now users can pass arguments to gplink via the
8926 -Wl option, main() uses pic16glue() to glue up pic16 programs

8940 gpasm complaining and test the linkage with gplink, _linkCmd and
8941 _asmCmd changed to be more gplink and gpasm friendly
8942 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8943 produced an error when parsed, peep rule 12 is added to utilize
8944 movff, but it is commented out since the pCode does not support
8945 yet a command with 2 address arguments
8947 2003-05-18 <johan AT balder>
8949 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8976 2003-05-11 Borut Razem <borut.razem AT siol.net>
8978 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9971 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9972 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9973 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9974 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

9982 2003-01-06 <johan AT balder>
9984 * src/SDCCicode.c: fixed array add
9986 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9987 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9988 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9990 2003-01-04 <johan AT balder>
9992 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9994 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9995 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9997 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9998 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9999 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10001 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10002 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10004 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10005 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10007 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10008 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10010 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10012 * in \sdcc\as\mcs51\ changed these files in order to create an
10013 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10014 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10015 following files to include the previous two files: aslink.dsp,
10016 Makefile.aslink, Makefile.bcc, and Makefile.in.
10018 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10019 .adb instead of .cdb
10021 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10023 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10024 value from option --iram-size.
10026 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10028 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10031 2002-09-18 <wiml AT hhhh.org>
10033 * SDCClrange.h: exposed setFromRange() and setToRange()
10034 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10035 packRegsForAccUse() (bug 542397)
10036 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10037 multiple times and emitting the fetch operations more than once
10038 added aopGetUsesAcc() function to allow binary operators to
10039 fetch their operands in the correct order; made genMinus() emit
10040 compact code for X = LITERAL - Y
10042 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10043 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10044 sprintf() in line 1267.
10046 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10047 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10050 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10051 Changes to aslink (All the changes are marked with 'JCF'):
10053 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10056 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10057 area BSEG. Also moves, if possible, the DATA area down into the internal
10058 ram so more space is available.
10060 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10063 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10064 not bytes. Function summary() which creates a memory usage summary
10065 file with extension .mem. Reports of overlaping stack and small stack
10066 size. If the space for the stack is less than 16 bytes aslink trows a
10069 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10070 the 8051. Option 'y' for memory summary output file.
10072 Changes to sdcc (All the changes are marked with 'JCF'):
10074 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10076 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10077 overlaying area for it (uses RegBankUsed[4]).
10079 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10080 bank zero as used by default. By default aslink locates the stack
10081 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10082 the creation of the .mem file. Delegates the allocation of data area
10083 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10084 the begining of the stack area to aslink.
10086 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10087 glue() in SDCCglue.c creates an area for it.
10089 2002-09-03 Borut Razem <borut.razem AT siol.net>
10090 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10091 sdcc/src/pic/glue.c:
10092 introduced atexit() handler for teporay files removal in case of
10093 errors, assertions, ...
10095 2002-08-29 Borut Razem <borut.razem AT siol.net>
10096 * sdcc/support/cpp2/auto-host_vc_in.h:
10097 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10098 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10099 Maybe there is a similar problem with BORLANDC? It should be checked!
10101 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10102 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10103 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10104 was not executed, and the compiler (cl) launched a warning:
10105 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10107 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10108 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10110 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10111 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10113 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10114 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10115 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10116 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10117 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10118 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10119 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10120 - added Release configuration in VS projects
10121 - review of compiler an linker options
10122 - VC .exe files are generated in bin_vc directory, not to interfere
10123 with binaries generated from other projects (cygwin, mingw, bcc ...)
10125 * sdcc/src/yacc.dsp: added
10127 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10128 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10129 and insert the version number definitions from .version
10131 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10133 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10134 added - genarate auto-host.h using auto-host_vc_in.h as template
10137 removed from CVS, generated automatically
10139 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10140 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10142 2002-08-11 Borut Razem <borut.razem AT siol.net>
10143 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10145 2002-08-10 Borut Razem <borut.razem AT siol.net>
10146 * src/SDCCmain.c (main):
10147 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10148 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10149 The consequence was that some temporary files were not removed.
10152 unification of code in functions tempfilename() and tempfile():
10153 function tempnam() is defined in Visual Studio 6.0 and .NET
10155 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10157 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10158 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10159 - removed compiler command line option /WX: Treats all warnings as errors
10160 - update a list of source files, included into the project
10162 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10163 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10164 changed project type to Generic Project so that can be correcly converted to VS.NET project
10166 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10168 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10170 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10172 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10173 added return 0 statements after assert() to make compiler happy
10175 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10176 added newline in the def file to keep MSC compiler satisfied
10178 * sdcc/src/z80/gen.c:
10179 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10180 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10181 - solved MSC error in function aopDump()
10183 * sdcc_vc.h: define PREFIX as "\\sdcc"
10185 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10186 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10189 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10190 - Rewrote the register banking algorithm.
10191 - Added pCode live-range analysis to registers (for now, only non-used and
10192 singly-used registers optimized away)
10194 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10196 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

10219 * src/z80/main.c: Added force callee saves for jaune.
10221 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10223 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10225 2002-03-28 Johan Knol <johan AT balder>
10227 * src/SDCCval.c: fixed bug #532436
10229 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10231 Added "char *Processor" field to the port structure.
10234 Added -p option. Allows port dependent processor to be specified.
10237 Initialized the new field char *Processor field to NULL in all ports
10240 Compiler generated registers for interrupt context saving
10241 were not getting allocated.
10243 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10246 Fixed left shift. Will promote the left side of a left shift
10247 if a) left shifting more than size of operand or b) when assigned
10248 to something size > size of left side
10250 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10252 tons of changes. Register allocation has been
10253 rewritten. Added customization for the various PICs. Flow
10254 analysis is restructured. ...
10256 * src/pic/device.h:
10259 * src/pic/device.c:
10260 Added. device.c is a PIC port hack to accomodate variations
10263 2002-03-13 Michael Hope <michaelh AT vroom>
10265 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10267 2002-03-04 johanknol <johanknol AT manik>
10269 * /src/SDCCval.c: fixed
10271 const unsigned char arr[][2] = { { 0, 1 } };
10272 t18.c:1: error: Initializer element is not constant

10358 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10360 * sdcc/src/SDCCloop.c:
10361 Previous fix was not good. basic blocks that have "break" or "return" are
10362 not really partof a loop , but live ranges used in these blocks should
10363 be live thru the entire loop, so set partOfLoop but don't add them to
10366 2002-02-21 <johan AT FRIJA>
10368 * src/SDCCcse.c: fixed bug #514308
10370 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10373 Fixed BUG #519583. If a conditional block ended in a return/break
10374 statement inside a loop, it was not being considered part of the loop.
10376 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10378 2002-02-10 Karl Bongers <karl AT turbobit.com>

10382 with lots of comments and notes.
10384 * device/examples/test2.c:
10385 Fix bug, "red" variable not being initialized(compiler complained).
10387 * device/examples/Makefile, examples/test3.c:
10388 Add Makefile in device/examples folder, compiles test3.c
10389 for use as a multiple module SDCDB test case.
10391 * sim/ucsim/cmd.src/cmdset.cc:
10392 Took out debug printfs in ucsim "next" command.
10394 * sim/ucsim/xa.src:
10395 Karl and Johan start ucsim XA support. Most dissassembly working,
10396 about 75% emulation done(plenty of work remaining).
10398 * sim/ucsim/z80.src:
10399 Add Z80 support to ucsim, add test-ucz80 regression test,
10400 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10401 Notice z80 compiler fails on examples/test3.c/crc code.
10403 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10405 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10413 from a memory mapped port
10414 2) added __builtin_memcmp
10415 3) added __builtin_swapw swap bytes of a short
10417 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10418 1) handle multiple send & receives from register bank1
10419 2) ralloc can now allocate DPTR1 to some liveRanges
10421 * src/SDCCsymt.c, src/SDCCsymt.h:
10422 changes to handle multiple sends & receives
10424 * src/SDCCptropt.h:
10425 added some pointer arithmetic optimization
10427 * src/SDCCptropt.c:
10428 added some pointer arithmetic optimizations but not stable yet so not
10429 called from anywhere (will get this working shortly)
10431 * src/SDCCopt.c: fixed for multiple sends & receives
10434 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10435 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10436 set preprocessor defines (depending on options)
