124 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
126 Enabled VPATH feature: changed nearly all Makefiles (149 files).
127 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
129 One basic decision: e.g. src/clean.mk includes further files. In order
130 to make this work there are two solutions:
131 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
132 run configure on them. This way they can use
133 'include $(srcdir)/port-clean.mk'
134 - always include clean.mk by the Makefile at the same level. To avoid
135 that `make clean` tries to include and build Makefile.dep the
136 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
137 implemented, because now even `make uninstall` doesn't create
138 Makefile.in. clean.mk could be eliminated by pasting it in
141 * debugger/mcs51/Makefile.in: build own objects from library sources
142 (SLIB, SDCC) in current directory
144 * configure, configure.in: renamed --disable-device-lib-build in
145 --disable-device-lib; added --enable-doc, the required tools are
146 searched by configure; added result message; the toolchain for the
147 belonging ports are now only built, if the port is enabled.
149 * support/regression/*: all output is written in directory gen, because
150 the fwk and ports directories don't livet in the build tree using vpath
152 * doc/sdccman.lyx: renamed --disable-device-lib-build to
153 --disable-device-lib, added --enable-doc, added section VPATH
155 * sim/ucsim/configure.in,
156 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
157 z80 are enabled by default
159 2006-04-24 Raphael Neider <rneider AT web.de>
161 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
162 to config word, "pic14_"-prefixed some extern functions
163 (pic14_emitConfigWord): emit __config directive(s) if assignment to
164 config word has been found
165 * src/pic/device.h: added prototypes
166 * src/pic/pcode.c: added "pic14_"-prefix where needed
167 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
169 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

182 registers that have not been assigned proper liveranges,
183 fixes #1469504 and #1474602,
184 (pCodeRegOptimizeRegUsage): fixed typo in comment

467 calling function in absolute addresses,
468 (genAssign): take into account AOP_ACC asmop,
469 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

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

538 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
539 which dumps before the function entry point a data byte which represents
540 the number of the local variables used by the specified function, added
541 'xinst' for initial support for Extended Instruction Support,
542 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
543 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
544 port->fun_prefix anymore (may change later),
545 (genFunction, genEndFunction): do not store/restore local registers for

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

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

2837 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2838 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2839 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2840 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2841 always available in leading double underscore form. The C99 support is
2842 mostly missing, but it's a start.
2843 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2844 reserved identifier "__data".
2846 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2920 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2922 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2924 * device/lib/printf_large.c: removed inline assembly for portability and
2925 readability. Use printf_fast if speed or size are more important.
2926 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2927 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2929 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2931 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2932 prevent compiler warning
2934 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2936 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2937 moved to level 0 and declared as static. Also they are explicit
2938 placed in access bank. This was necessery because some times they
2939 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2940 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2941 optimizations. Currently only compare to unsigned char is implemented,
2942 * src/pic16/gen.c: added fReturnIdx array,
2943 * (struct resolvedIfx) is moved to gen.h and made public,
2944 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2945 * (aopForSym): added an optimization to directly store in stack of
2946 the operand of a SEND iCode,
2947 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2948 but as registers instead (AOP_REG) using the fReturnIdx array,
2949 * (pic16_freeAsmop): remove the freed register from the
2950 _G.sregsAlloc field,
2951 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2952 a compare of 'WREG',
2953 * (pic16_popGetTempRegCond): changed function prototype, now
2954 function takes also a bitVector argument v which holds the current
2955 set of registers that are allocated for stack access by aopForSym,
2956 registers allocated in aopForSym for accessing stack symbols are not
2957 any more part of the functions usedRegs field,
2958 * (genCall): some times aopOp is called for a stack variable to be
2959 send, aopForSym might perform the push, if this is true make sure
2960 that genCall doesn't push the variable twice by testing _G.resDirect,
2961 * (genFunction): changed testing for unspecified interrupt number
2962 from 256 to INTNO_UNSPEC,
2963 * modified selection scheme of frame pointer generation. Previously
2964 if function did use local registers a frame pointer was generated,
2965 now a frame pointer is generated only if function has arguments
2966 (that need PLUSW2 register access), or has stack arguments, or the
2967 compiler is not instructed to omit the frame pointer,
2968 * (genEndFunction): before restoring local registers that were saved
2969 in the function preamble, also restore the registers that *might*
2970 have been allocated for stack access,
2971 * (genRet): removed some old comments,
2972 * (genCmp, the active (RN's) version): added a call to the
2973 pic16_genCmp_special function to perform the compare with a more
2974 robust and optimized way,
2975 * (genInline): a feature has been added in inline code generation,
2976 which allows a wildcard variable substitution when writing inline
2977 assembly. Code is incomplete and experimental therefore undocumented,
2978 * (genCast): changed order of aopOp for result and right to allow
2979 aopForSym to directly load the result if possible,
2980 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2981 perform an optimized compare on some selected special occasions,
2982 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2983 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2984 generate an IVT any more,
2985 * src/pic16/main.c (pic16_optionsTable): added command line option
2987 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2988 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2990 * src/pic16/NOTES: Raphael Neider added in list of active developers
2991 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2992 jumptable_end to prevent bug #,
2993 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2994 inCond and outCond fields,
2995 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2996 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2997 turn off register spilling,
2998 * (packRegsForOneUse): synced with other ports' versions although it
2999 is not used currently,
3000 * (pic16_packRegisters): added an optimization while reading
3001 structure bitfields, some registers may be saved (malloc code is
3002 decreased by 80 bytes)
3004 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3006 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3007 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3008 this can be optimized more?
3010 2005-03-10 Raphael Neider <rneider AT web.de>
3012 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3013 genNearPointerGet): (hopefully) fixed access to bitfields via
3014 pointers (p->bitN = x; and x = p->bitN; failed)
3016 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3018 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3020 2005-03-09 Raphael Neider <rneider AT web.de>
3022 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
3024 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3026 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC

3648 Adding support for replacing ljmps with sjmps in jumptables
3649 generated for switch statements. For now you need to set the
3650 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3651 Now 4 algorithms for mcs51 jumptable generation are used:
3652 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3653 addresses loaded pc-relative for up to 112 cases and stack-pushing
3654 target addresses loaded with offset from dptr for up to 256 cases.

3684 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3686 * added libc directory. The current version of LibC contains string
3687 functions, ctype functions and macros and some functions of the
3688 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3689 be extensively tested in the future. Standard disclaimer here.
3690 Library is not automatically build yet. But one can build it by
3691 invoking 'make' inside the libc directory.

3702 * (pic16_storeForReturn): optimized return of 0,
3703 * (genCmp): experimental code for new genCmp which uses PIC18's
3704 special compare&skip instructions. Initial tests fail some times
3705 with variables grater than 1 byte in size, so new code is disabled,
3706 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3708 * (genCast): began a fix to optimize the casting of a bit to another
3709 bit, now assigning a bitfield to another bitfield will fail, sorry,

3718 and 1 for banking instruction,
3719 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3720 caused stop processing pCodes after a inline assembly block,
3721 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3722 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3723 registers when it shouldn't,
3724 * src/pic16/ralloc.c (allocReg): add preliminary support for
3725 supporting a limited set of temporary registers,
3727 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3729 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3733 (genFunction): optimize RECEIVE iCodes in reentrant functions
3735 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3737 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6735 loaded with the linker search paths (-L arguments) and the libraries
6736 to be linked with the current source (-l arguments). Changes
6737 currently will affect only the pic16 port.
6738 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6739 include path the port specific paths and port specific libraries,
6740 * gplink command now contains the $3 argument,
6741 * src/pic16/device.h,

6758 Documenting changes from previous commits.
6759 * configure.in (version 1.56),
6760 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6761 when generating output files to configure the pic16 library,
6762 but now I've commented it out, since gputils aren't installed in the
6763 SF compile farm, so library won't compile
6765 * device/lib/Makefile.in (version 1.56): initially I've added in
6766 target 'all' the prerequestive 'model-pic16' so it compiled the
6767 pic16 library, but now I've commented it out for the same reasons
6769 * added targets 'model-pic16' and 'objects-pic16' to compile the
6771 * added target 'port-specific-objects-pic16' to handle the
6772 generated libraries and copy them into the build/ directory
6773 * added target 'clean-intermediate-pic16' to clean intermediate
6774 files into pic16 directory
6775 * in target 'installdirs' added line to create directory pic16 in

7040 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7041 * src/SDCCsymt.c (newEnumType),
7043 * support/Util/SDCCerr.c,
7044 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7046 * support/regression/tests/enum.c: added test for enum values that
7047 require at least 2 bytes of storage.
7049 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7051 * src/common.h: added ifndef/define/endif macros
7052 around the header file.
7053 Bug reported from Jesus Calvino-Fraga
7055 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7057 * sdcc.spec: updated
7058 * device/include/Makefile.in: don't install CVS directories
7059 * device/lib/Makefile.in: added removal of CVS directories after install
7060 * doc/Makefile: fixed install, added local_icons
7061 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7062 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7063 * src/ds390/gen.c (genRightShift): fixed bug #870788
7064 * src/SDCCast.c (decorateType): fixed bug #870781
7066 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7068 PIC16 port related changes:
7069 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7070 added variable stackPos,
7072 * gen.c: genCall, assignResultValue: added support for
7073 pushing/retrieving function parameters to/from stack,
7074 genFunction,genEndFunction: setup stack frame for the
7076 genAddrOf: will be changed according to bug 863624
7078 * added files genutils.c and genutils.h which contain gen*
7079 debugged and optimised functions extracted from gen.c
7081 * glue.c: added variable 'externs' which holds extern symbols,
7082 pic16emitRegularMap: is modified to properly handle relocatable
7083 symbols under the new scheme,
7084 pic16createInterruptVect: is modified
7085 pic16printPublics: is modified to emit 'global' assembler directives,
7086 added pic16_printExterns to print extern symbols,
7087 pic16glue: initializes stack/frame pointer in the beginning of
7088 the assembly output. Temporary hack, will be corrected later,
7089 because gplink yet does not support stack and SDCC does not
7090 yet support a type of crt0.o object to create the final binary.
7092 * Removed many lines that contain 8051 legacy code.
7093 * The code is finally placed under a 'code' directive.
7094 * Added port specific options.
7096 * _process_pragma: simplified since now we do not need *special*
7097 include file to define SFR registers. But a separate header
7098 will be needed. This will be developed later.
7099 * _pic16_parseOptions: added, parses port specific options:
7100 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7101 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7102 --preplace-udata-with=
7104 * _pic16_setDefaultOptions: modified to initialize section names,
7105 but hack is temporarly out of order since it needs improvement.
7106 * _pic16_genAssemblerPreamble: configuration words are emitted by
7107 their address instead of their name. This part is incomplete and
7108 supports only the 18Fxx2 devices. Other devices will emit an error
7109 during assembly since they do not contain the same set of config
7111 * _pic16_genIVT: is modified,
7113 * pcode.c: added definitions for some hardware registers that are needed
7115 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7116 All PCI entries are updated. Now LFSR is supported.
7117 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7118 * added pic16_newpCodeOpLit2 to support instructions with
7119 two literal arguments
7120 * pic16_pCode2str: corrected code that emits assembler instructions
7121 with two literal operands and those that have an access bit modifier
7122 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7123 this fixes a bug which caused some labels to be lost, when an
7124 assembler directive was added, i.e. banksel,
7125 * pic16_FixRegisterBanking: improved logic that causes the insertion
7127 * InlineFunction: functions that are called once, are not any more
7128 inlined. This can be a port option in the future,
7130 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7132 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7133 hold the corresponding uninitialized symbols,
7134 * pic16_allocProcessorRegister: registers have explicit marked the
7136 * pic16_allocInternalRegister: registers are explicit marked as
7138 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7139 processing list, so bit registers were lost,
7142 * ralloc.h: added field 'accessBank' and original symbol operand
7143 in register definition,
7144 * removed the field isMapped from register definition,
7146 ** Several functions have been removed from various sources:
7147 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7148 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7149 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7150 pic16_assignRelocatableRegisters
7152 ** others have been introduced:
7153 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7154 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7156 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7158 * support/scripts/inc2h.pl: changed definition of BIT_AT
7159 to emit 'sbit at' instead of 'bit at'. This was a request.
7161 PIC16 port related preliminary changes:
7162 * gen.c: prefixed function popRegFromString with
7163 pic16_ and all references to it corrected
7164 * pcode.c: all pic16_pc_* hardware registers prefixed
7165 with underscore (_),
7166 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7167 * ralloc.c: newReg(): when register is REG_SFR then
7168 set address to rIdx,
7169 pic16_allocProcessorRegister(): marks register wasUsed=0
7170 pic16_writeUsedRegs(): added a call to assign processor
7171 registers via pic16_assignFixedRegisters
7173 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7175 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7176 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7177 variables in unused register banks. Also the SSEG is placed
7178 wherever there is enough space for it, and IDATA can be anywhere
7179 in internal RAM. For now compile using -Wl-Y[stack_size].
7180 The mem file is different for this option as well, since it
7181 makes no sense of talking about DSEG lenght.
7183 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7185 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7186 in certain cases, e.g. when ROM assignment, patch provided
7187 from Albert den Haan.

7332 * src/mcs51/peephole.def,
7333 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7428 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7430 * src/SDCCast.c (decorateType): disabled a transformation I added in
7431 revision 1.188 (access to fields of a structure at an absolute address);
7432 it breaks with bitfields, extern declarations, and gcse analysis.
7433 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7434 could be assigned through a pointer, so don't complain.
7435 * src/SDCCast.c (astErrors),
7437 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8075 support for standard C idiom of memory mapped variables; for
8076 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8077 to xdata int at 0x1234 tempvar = 1.
8078 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8079 provided by Akiya ISHIDA

8191 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8192 fetching of the pointer
8193 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8194 copied from genNearPointerSet()
8195 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8196 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8212 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8213 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8214 type for bits was changed. It resulted in bit variables becoming
8215 global, which is not permitted in PIC 14 assembly output.
8217 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8219 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8232 A few small changes that speed up the peephole optimizer.
8236 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8238 Try to make the peephole optimizer smarter by maintaining
8239 an association between the assembly source code and the
8240 iCodes that originated them. Put this information to use
8241 with a new peephole rule condition "notVolatile" so that
8242 the rules can be aggressive yet still safe.
8247 * src/mcs51/peeph.def
8249 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8253 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8254 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8255 if the left or right operand symbols have the accuse flag set.
8257 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8259 Changed the type of the result of the ! (NOT) operator to char;
8260 previously it returned the same type as the source. This allows
8261 us to eliminate all the genFloatNot functions (all of its target
8262 implementations were very buggy) since !float can use the same

8274 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8275 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8276 during interrupts. Ensure WSAVE is located at a shared bank address.
8277 2. Fixed page selection in some places
8278 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8279 the registers name strings.
8280 4. Fixed "signed / unsigned compare" compiler warnings.
8281 5. The PIC port manages its own allocation of the general purpose
8282 registers, but makes no attempt to reuse them. As a result when
8283 compiling it soon runs out of general purpose registers. Some
8284 additional code was added to the files pcode.c and device.c to walk
8285 through the function call tree and rename the registers so that they
8295 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8296 genPlus() & genMinus() when the result is the same as left or right

8302 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8304 Made bitfield a distinct type from bit so that bitfields
8305 convert as per ANSI C and bits retain their traditional
8306 boolean style behaviour. Implemented bitfield support in
8314 * src/ds390/gen.c: bit v bitfield split
8315 * src/z80/gen.c: New support for bitfields
8316 * support/regression/tests/bitfields.c: reenabled z80,
8319 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8321 Rules 246.x, 247.x relate to bitfields, the others speed up
8322 access to xdata mapped I/O devices.
8324 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8326 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8328 Cleaned up genPackBits and genUnpackBits and added two helper
8329 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8330 for literal assignments in genPackBits (thanks to Frieder for
8336 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8338 Fixed bug #748310 (pointer to function type mishandled when the
8339 function name is omitted). Also fixed a SIGSEGV when a function
8340 attribute (reentrant, etc) is used on a non-function or on a
8341 function but misplaced before the parameter list.
8343 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8345 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8346 * support/Util/SDCCerr.h,

8368 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8370 Made the constant following the "interrupt" keyword optional. If
8371 omitted, the function will not automatically be given an entry
8372 in the interrupt vector table (similar to #pragma NOIV, but
8373 less syntacticly kludgy). The interrupt number is also now
8374 range checked. Also fixed a bug in the high order bit example

8388 * src/SDCCicode.c (operandOperation): rewritten some ops
8389 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8390 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8392 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8393 be re-activated by defining REDUCE_LITERALS)
8394 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8395 unsigned, but are signed by default
8396 * src/SDCCval.c (constVal): rearranged
8397 * src/SDCCval.c (valMod): preliminary fix
8398 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8904 added if/endif conditional macros to remove options help
8905 messages from optionsTable when a port is not configured, added
8906 support for the PIc16 port in the ports table, when executing
8907 the compiler with no port specified on command line, a default
8908 port is selected with the new macro DEFAULT_PORT which is
8909 defined in port.h, in setDefaultOptions() linkOptions is removed
8910 from initialization assignment, since now it is a set,
8911 parseCmdLine uses setParseWithComma for linkOptions, in
8912 linkEdit() linkOptions are accessed with new function indexSet()
8913 which returns the i'th item of a set variable. See SDCCset.c, in
8914 linkEdit() when calling buildCmdLine(), added linkOptions as
8915 last argument. Now users can pass arguments to gplink via the
8916 -Wl option, main() uses pic16glue() to glue up pic16 programs

8930 gpasm complaining and test the linkage with gplink, _linkCmd and
8931 _asmCmd changed to be more gplink and gpasm friendly
8932 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8933 produced an error when parsed, peep rule 12 is added to utilize
8934 movff, but it is commented out since the pCode does not support
8935 yet a command with 2 address arguments
8937 2003-05-18 <johan AT balder>
8939 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8966 2003-05-11 Borut Razem <borut.razem AT siol.net>
8968 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9972 2003-01-06 <johan AT balder>
9974 * src/SDCCicode.c: fixed array add
9976 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9977 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9978 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9980 2003-01-04 <johan AT balder>
9982 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9984 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9985 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9987 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9988 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9989 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9991 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9992 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9994 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9995 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9997 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9998 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10000 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10002 * in \sdcc\as\mcs51\ changed these files in order to create an
10003 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10004 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10005 following files to include the previous two files: aslink.dsp,
10006 Makefile.aslink, Makefile.bcc, and Makefile.in.
10008 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10009 .adb instead of .cdb
10011 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10013 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10014 value from option --iram-size.
10016 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10018 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10021 2002-09-18 <wiml AT hhhh.org>
10023 * SDCClrange.h: exposed setFromRange() and setToRange()
10024 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10025 packRegsForAccUse() (bug 542397)
10026 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10027 multiple times and emitting the fetch operations more than once
10028 added aopGetUsesAcc() function to allow binary operators to
10029 fetch their operands in the correct order; made genMinus() emit
10030 compact code for X = LITERAL - Y
10032 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10033 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10034 sprintf() in line 1267.
10036 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10037 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10040 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10041 Changes to aslink (All the changes are marked with 'JCF'):
10043 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10046 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10047 area BSEG. Also moves, if possible, the DATA area down into the internal
10048 ram so more space is available.
10050 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10053 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10054 not bytes. Function summary() which creates a memory usage summary
10055 file with extension .mem. Reports of overlaping stack and small stack
10056 size. If the space for the stack is less than 16 bytes aslink trows a
10059 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10060 the 8051. Option 'y' for memory summary output file.
10062 Changes to sdcc (All the changes are marked with 'JCF'):
10064 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10066 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10067 overlaying area for it (uses RegBankUsed[4]).
10069 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10070 bank zero as used by default. By default aslink locates the stack
10071 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10072 the creation of the .mem file. Delegates the allocation of data area
10073 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10074 the begining of the stack area to aslink.
10076 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10077 glue() in SDCCglue.c creates an area for it.
10079 2002-09-03 Borut Razem <borut.razem AT siol.net>
10080 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10081 sdcc/src/pic/glue.c:
10082 introduced atexit() handler for teporay files removal in case of
10083 errors, assertions, ...
10085 2002-08-29 Borut Razem <borut.razem AT siol.net>
10086 * sdcc/support/cpp2/auto-host_vc_in.h:
10087 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10088 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10089 Maybe there is a similar problem with BORLANDC? It should be checked!
10091 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10092 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10093 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10094 was not executed, and the compiler (cl) launched a warning:
10095 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10097 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10098 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10100 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10101 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10103 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10104 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10105 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10106 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10107 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10108 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10109 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10110 - added Release configuration in VS projects
10111 - review of compiler an linker options
10112 - VC .exe files are generated in bin_vc directory, not to interfere
10113 with binaries generated from other projects (cygwin, mingw, bcc ...)
10115 * sdcc/src/yacc.dsp: added
10117 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10118 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10119 and insert the version number definitions from .version
10121 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10123 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10124 added - genarate auto-host.h using auto-host_vc_in.h as template
10127 removed from CVS, generated automatically
10129 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10130 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10132 2002-08-11 Borut Razem <borut.razem AT siol.net>
10133 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10135 2002-08-10 Borut Razem <borut.razem AT siol.net>
10136 * src/SDCCmain.c (main):
10137 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10138 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10139 The consequence was that some temporary files were not removed.
10142 unification of code in functions tempfilename() and tempfile():
10143 function tempnam() is defined in Visual Studio 6.0 and .NET
10145 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10147 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10148 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10149 - removed compiler command line option /WX: Treats all warnings as errors
10150 - update a list of source files, included into the project
10152 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10153 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10154 changed project type to Generic Project so that can be correcly converted to VS.NET project
10156 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10158 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10160 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10162 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10163 added return 0 statements after assert() to make compiler happy
10165 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10166 added newline in the def file to keep MSC compiler satisfied
10168 * sdcc/src/z80/gen.c:
10169 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10170 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10171 - solved MSC error in function aopDump()
10173 * sdcc_vc.h: define PREFIX as "\\sdcc"
10175 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10176 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10179 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10180 - Rewrote the register banking algorithm.
10181 - Added pCode live-range analysis to registers (for now, only non-used and
10182 singly-used registers optimized away)
10184 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10186 * 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.

10211 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10213 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10215 2002-03-28 Johan Knol <johan AT balder>
10217 * src/SDCCval.c: fixed bug #532436
10219 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10221 Added "char *Processor" field to the port structure.
10224 Added -p option. Allows port dependent processor to be specified.
10227 Initialized the new field char *Processor field to NULL in all ports
10230 Compiler generated registers for interrupt context saving
10231 were not getting allocated.
10233 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10236 Fixed left shift. Will promote the left side of a left shift
10237 if a) left shifting more than size of operand or b) when assigned
10238 to something size > size of left side
10240 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10242 tons of changes. Register allocation has been
10243 rewritten. Added customization for the various PICs. Flow
10244 analysis is restructured. ...
10246 * src/pic/device.h:
10249 * src/pic/device.c:
10250 Added. device.c is a PIC port hack to accomodate variations
10253 2002-03-13 Michael Hope <michaelh AT vroom>
10255 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10257 2002-03-04 johanknol <johanknol AT manik>
10259 * /src/SDCCval.c: fixed
10261 const unsigned char arr[][2] = { { 0, 1 } };

10348 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10350 * sdcc/src/SDCCloop.c:
10351 Previous fix was not good. basic blocks that have "break" or "return" are
10352 not really partof a loop , but live ranges used in these blocks should
10353 be live thru the entire loop, so set partOfLoop but don't add them to
10356 2002-02-21 <johan AT FRIJA>
10358 * src/SDCCcse.c: fixed bug #514308
10360 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10363 Fixed BUG #519583. If a conditional block ended in a return/break
10364 statement inside a loop, it was not being considered part of the loop.
10366 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10368 2002-02-10 Karl Bongers <karl AT turbobit.com>

10382 Took out debug printfs in ucsim "next" command.
10384 * sim/ucsim/xa.src:
10385 Karl and Johan start ucsim XA support. Most dissassembly working,
10386 about 75% emulation done(plenty of work remaining).
10388 * sim/ucsim/z80.src:
10389 Add Z80 support to ucsim, add test-ucz80 regression test,
10390 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10391 Notice z80 compiler fails on examples/test3.c/crc code.
10393 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

10407 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10408 1) handle multiple send & receives from register bank1
10409 2) ralloc can now allocate DPTR1 to some liveRanges
10411 * src/SDCCsymt.c, src/SDCCsymt.h:
10412 changes to handle multiple sends & receives
10414 * src/SDCCptropt.h:
10415 added some pointer arithmetic optimization
10417 * src/SDCCptropt.c:

10424 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10425 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10426 set preprocessor defines (depending on options)
10428 * src/SDCCicode.c, src/SDCCicode.h:
10429 changes made to handle multiple sends & receives
