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

465 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
466 call to allocReg, not by manually allocating a new one,
467 (pic16_assignRegisters): now before going through the register
468 allocating functions mark all registers as free. This eliminates some
469 side effects resulting from peephole parser done earlier in the backbone
471 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

492 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
493 (aopForSym, aopOp): increment asmop.allocated if reused,

504 in reverse order from allocation,
505 (genPlus, genCmpEq): free asmop's in reverse order from allocation and
506 added swappedLR to keep track

518 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
519 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
521 2006-03-06 Borut Razem <borut.razem AT siol.net>
523 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
524 made the linker quiet

528 * src/pic16/gen.c (genPcall): fixed bug #1443644
529 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
530 which dumps before the function entry point a data byte which represents
531 the number of the local variables used by the specified function, added
532 'xinst' for initial support for Extended Instruction Support,
533 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
534 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
535 port->fun_prefix anymore (may change later),
536 (genFunction, genEndFunction): do not store/restore local registers for
537 _main (this should take care the --main-return command line option in
539 (genOr): removed some legacy pic-port instructions,
540 * src/pic16/genarith.c (genAddLit): re-enabled old code because
541 performing operations with SFR's causes data to be written more than
542 once to each SFR. Perhaps SFRs should be handled in special cases...
543 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
545 * src/pic16/main.c (_process_pragma): stack bound checking did not take

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

2828 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2829 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2830 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2831 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2832 always available in leading double underscore form. The C99 support is

2911 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2913 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2915 * device/lib/printf_large.c: removed inline assembly for portability and
2916 readability. Use printf_fast if speed or size are more important.
2917 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2918 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2920 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2922 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2923 prevent compiler warning
2925 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2927 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2928 moved to level 0 and declared as static. Also they are explicit
2929 placed in access bank. This was necessery because some times they
2930 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2931 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2932 optimizations. Currently only compare to unsigned char is implemented,
2933 * src/pic16/gen.c: added fReturnIdx array,
2934 * (struct resolvedIfx) is moved to gen.h and made public,
2935 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2936 * (aopForSym): added an optimization to directly store in stack of
2937 the operand of a SEND iCode,
2938 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2939 but as registers instead (AOP_REG) using the fReturnIdx array,
2940 * (pic16_freeAsmop): remove the freed register from the
2941 _G.sregsAlloc field,
2942 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2943 a compare of 'WREG',
2944 * (pic16_popGetTempRegCond): changed function prototype, now
2945 function takes also a bitVector argument v which holds the current
2946 set of registers that are allocated for stack access by aopForSym,
2947 registers allocated in aopForSym for accessing stack symbols are not
2948 any more part of the functions usedRegs field,
2949 * (genCall): some times aopOp is called for a stack variable to be
2950 send, aopForSym might perform the push, if this is true make sure
2951 that genCall doesn't push the variable twice by testing _G.resDirect,
2952 * (genFunction): changed testing for unspecified interrupt number
2953 from 256 to INTNO_UNSPEC,
2954 * modified selection scheme of frame pointer generation. Previously
2955 if function did use local registers a frame pointer was generated,
2956 now a frame pointer is generated only if function has arguments
2957 (that need PLUSW2 register access), or has stack arguments, or the
2958 compiler is not instructed to omit the frame pointer,
2959 * (genEndFunction): before restoring local registers that were saved
2960 in the function preamble, also restore the registers that *might*
2961 have been allocated for stack access,
2962 * (genRet): removed some old comments,
2963 * (genCmp, the active (RN's) version): added a call to the
2964 pic16_genCmp_special function to perform the compare with a more
2965 robust and optimized way,
2966 * (genInline): a feature has been added in inline code generation,
2967 which allows a wildcard variable substitution when writing inline
2968 assembly. Code is incomplete and experimental therefore undocumented,
2969 * (genCast): changed order of aopOp for result and right to allow
2970 aopForSym to directly load the result if possible,
2971 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2972 perform an optimized compare on some selected special occasions,
2973 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2974 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2975 generate an IVT any more,
2976 * src/pic16/main.c (pic16_optionsTable): added command line option
2978 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2979 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2981 * src/pic16/NOTES: Raphael Neider added in list of active developers
2982 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2983 jumptable_end to prevent bug #,
2984 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2985 inCond and outCond fields,
2986 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2987 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2988 turn off register spilling,
2989 * (packRegsForOneUse): synced with other ports' versions although it
2990 is not used currently,
2991 * (pic16_packRegisters): added an optimization while reading
2992 structure bitfields, some registers may be saved (malloc code is
2993 decreased by 80 bytes)
2995 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2997 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2998 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2999 this can be optimized more?
3001 2005-03-10 Raphael Neider <rneider AT web.de>
3003 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3004 genNearPointerGet): (hopefully) fixed access to bitfields via
3005 pointers (p->bitN = x; and x = p->bitN; failed)
3007 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3009 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3011 2005-03-09 Raphael Neider <rneider AT web.de>

3015 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3017 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
3018 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
3019 (regTypeNum): set REG_BIT type if necessary
3020 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

3639 Adding support for replacing ljmps with sjmps in jumptables
3640 generated for switch statements. For now you need to set the
3641 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3642 Now 4 algorithms for mcs51 jumptable generation are used:
3643 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3644 addresses loaded pc-relative for up to 112 cases and stack-pushing
3645 target addresses loaded with offset from dptr for up to 256 cases.

3675 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3677 * added libc directory. The current version of LibC contains string
3678 functions, ctype functions and macros and some functions of the
3679 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3680 be extensively tested in the future. Standard disclaimer here.
3681 Library is not automatically build yet. But one can build it by
3682 invoking 'make' inside the libc directory.

3693 * (pic16_storeForReturn): optimized return of 0,
3694 * (genCmp): experimental code for new genCmp which uses PIC18's
3695 special compare&skip instructions. Initial tests fail some times
3696 with variables grater than 1 byte in size, so new code is disabled,
3697 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3699 * (genCast): began a fix to optimize the casting of a bit to another
3700 bit, now assigning a bitfield to another bitfield will fail, sorry,

3709 and 1 for banking instruction,
3710 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3711 caused stop processing pCodes after a inline assembly block,
3712 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3714 registers when it shouldn't,
3715 * src/pic16/ralloc.c (allocReg): add preliminary support for
3716 supporting a limited set of temporary registers,
3718 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3720 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3724 (genFunction): optimize RECEIVE iCodes in reentrant functions
3726 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6726 loaded with the linker search paths (-L arguments) and the libraries
6727 to be linked with the current source (-l arguments). Changes
6728 currently will affect only the pic16 port.
6729 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6730 include path the port specific paths and port specific libraries,
6731 * gplink command now contains the $3 argument,
6732 * src/pic16/device.h,
6733 * src/pic16/device.c,: structure PIC_device is made public and
6734 renamed to PIC16_device, the same for variable Pics which is renamed

6749 Documenting changes from previous commits.
6750 * configure.in (version 1.56),
6751 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6752 when generating output files to configure the pic16 library,
6753 but now I've commented it out, since gputils aren't installed in the
6754 SF compile farm, so library won't compile
6756 * device/lib/Makefile.in (version 1.56): initially I've added in
6757 target 'all' the prerequestive 'model-pic16' so it compiled the
6758 pic16 library, but now I've commented it out for the same reasons
6760 * added targets 'model-pic16' and 'objects-pic16' to compile the
6762 * added target 'port-specific-objects-pic16' to handle the
6763 generated libraries and copy them into the build/ directory
6764 * added target 'clean-intermediate-pic16' to clean intermediate
6765 files into pic16 directory
6766 * in target 'installdirs' added line to create directory pic16 in

7032 * src/SDCCsymt.c (newEnumType),
7034 * support/Util/SDCCerr.c,
7035 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7037 * support/regression/tests/enum.c: added test for enum values that
7038 require at least 2 bytes of storage.
7040 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7042 * src/common.h: added ifndef/define/endif macros
7043 around the header file.
7044 Bug reported from Jesus Calvino-Fraga
7046 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7048 * sdcc.spec: updated
7049 * device/include/Makefile.in: don't install CVS directories
7050 * device/lib/Makefile.in: added removal of CVS directories after install
7051 * doc/Makefile: fixed install, added local_icons
7052 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7053 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7054 * src/ds390/gen.c (genRightShift): fixed bug #870788
7055 * src/SDCCast.c (decorateType): fixed bug #870781
7057 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7059 PIC16 port related changes:
7060 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7061 added variable stackPos,
7063 * gen.c: genCall, assignResultValue: added support for
7064 pushing/retrieving function parameters to/from stack,
7065 genFunction,genEndFunction: setup stack frame for the
7067 genAddrOf: will be changed according to bug 863624
7069 * added files genutils.c and genutils.h which contain gen*
7070 debugged and optimised functions extracted from gen.c
7072 * glue.c: added variable 'externs' which holds extern symbols,
7073 pic16emitRegularMap: is modified to properly handle relocatable
7074 symbols under the new scheme,
7075 pic16createInterruptVect: is modified
7076 pic16printPublics: is modified to emit 'global' assembler directives,
7077 added pic16_printExterns to print extern symbols,
7078 pic16glue: initializes stack/frame pointer in the beginning of
7079 the assembly output. Temporary hack, will be corrected later,
7080 because gplink yet does not support stack and SDCC does not
7081 yet support a type of crt0.o object to create the final binary.
7083 * Removed many lines that contain 8051 legacy code.
7084 * The code is finally placed under a 'code' directive.
7085 * Added port specific options.
7087 * _process_pragma: simplified since now we do not need *special*
7088 include file to define SFR registers. But a separate header
7089 will be needed. This will be developed later.
7090 * _pic16_parseOptions: added, parses port specific options:
7091 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7092 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7093 --preplace-udata-with=
7095 * _pic16_setDefaultOptions: modified to initialize section names,
7096 but hack is temporarly out of order since it needs improvement.
7097 * _pic16_genAssemblerPreamble: configuration words are emitted by
7098 their address instead of their name. This part is incomplete and
7099 supports only the 18Fxx2 devices. Other devices will emit an error
7100 during assembly since they do not contain the same set of config
7102 * _pic16_genIVT: is modified,
7104 * pcode.c: added definitions for some hardware registers that are needed
7106 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7107 All PCI entries are updated. Now LFSR is supported.
7108 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7109 * added pic16_newpCodeOpLit2 to support instructions with
7110 two literal arguments
7111 * pic16_pCode2str: corrected code that emits assembler instructions
7112 with two literal operands and those that have an access bit modifier
7113 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7114 this fixes a bug which caused some labels to be lost, when an
7115 assembler directive was added, i.e. banksel,
7116 * pic16_FixRegisterBanking: improved logic that causes the insertion
7118 * InlineFunction: functions that are called once, are not any more
7119 inlined. This can be a port option in the future,
7121 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7123 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7124 hold the corresponding uninitialized symbols,
7125 * pic16_allocProcessorRegister: registers have explicit marked the
7127 * pic16_allocInternalRegister: registers are explicit marked as
7129 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7130 processing list, so bit registers were lost,
7133 * ralloc.h: added field 'accessBank' and original symbol operand
7134 in register definition,
7135 * removed the field isMapped from register definition,
7137 ** Several functions have been removed from various sources:
7138 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7139 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7140 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7141 pic16_assignRelocatableRegisters
7143 ** others have been introduced:
7144 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7145 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7147 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7149 * support/scripts/inc2h.pl: changed definition of BIT_AT
7150 to emit 'sbit at' instead of 'bit at'. This was a request.
7152 PIC16 port related preliminary changes:
7153 * gen.c: prefixed function popRegFromString with
7154 pic16_ and all references to it corrected
7155 * pcode.c: all pic16_pc_* hardware registers prefixed
7156 with underscore (_),
7157 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7158 * ralloc.c: newReg(): when register is REG_SFR then
7159 set address to rIdx,
7160 pic16_allocProcessorRegister(): marks register wasUsed=0
7161 pic16_writeUsedRegs(): added a call to assign processor
7162 registers via pic16_assignFixedRegisters
7164 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7166 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7167 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7168 variables in unused register banks. Also the SSEG is placed
7169 wherever there is enough space for it, and IDATA can be anywhere
7170 in internal RAM. For now compile using -Wl-Y[stack_size].
7171 The mem file is different for this option as well, since it
7172 makes no sense of talking about DSEG lenght.
7174 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7176 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7177 in certain cases, e.g. when ROM assignment, patch provided
7178 from Albert den Haan.

7323 * src/mcs51/peephole.def,
7324 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7419 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7421 * src/SDCCast.c (decorateType): disabled a transformation I added in
7422 revision 1.188 (access to fields of a structure at an absolute address);
7423 it breaks with bitfields, extern declarations, and gcse analysis.
7424 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7425 could be assigned through a pointer, so don't complain.
7426 * src/SDCCast.c (astErrors),
7428 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8066 support for standard C idiom of memory mapped variables; for
8067 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8068 to xdata int at 0x1234 tempvar = 1.
8069 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8070 provided by Akiya ISHIDA

8086 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8088 Fixed bug #621531 (const & volatile confusion in the type chain).
8089 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8182 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8183 fetching of the pointer
8184 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8185 copied from genNearPointerSet()
8186 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8187 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8201 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8203 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8204 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8205 type for bits was changed. It resulted in bit variables becoming
8206 global, which is not permitted in PIC 14 assembly output.
8208 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8210 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8223 A few small changes that speed up the peephole optimizer.
8227 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8229 Try to make the peephole optimizer smarter by maintaining
8230 an association between the assembly source code and the
8231 iCodes that originated them. Put this information to use
8232 with a new peephole rule condition "notVolatile" so that
8233 the rules can be aggressive yet still safe.
8238 * src/mcs51/peeph.def
8240 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8244 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8245 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8246 if the left or right operand symbols have the accuse flag set.
8248 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8250 Changed the type of the result of the ! (NOT) operator to char;
8251 previously it returned the same type as the source. This allows
8252 us to eliminate all the genFloatNot functions (all of its target
8253 implementations were very buggy) since !float can use the same

8265 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8266 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8267 during interrupts. Ensure WSAVE is located at a shared bank address.
8268 2. Fixed page selection in some places
8269 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8270 the registers name strings.
8271 4. Fixed "signed / unsigned compare" compiler warnings.
8272 5. The PIC port manages its own allocation of the general purpose
8273 registers, but makes no attempt to reuse them. As a result when
8274 compiling it soon runs out of general purpose registers. Some
8275 additional code was added to the files pcode.c and device.c to walk
8276 through the function call tree and rename the registers so that they
8286 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8287 genPlus() & genMinus() when the result is the same as left or right

8293 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8295 Made bitfield a distinct type from bit so that bitfields
8296 convert as per ANSI C and bits retain their traditional
8297 boolean style behaviour. Implemented bitfield support in
8305 * src/ds390/gen.c: bit v bitfield split
8306 * src/z80/gen.c: New support for bitfields
8307 * support/regression/tests/bitfields.c: reenabled z80,
8310 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8312 Rules 246.x, 247.x relate to bitfields, the others speed up
8313 access to xdata mapped I/O devices.
8315 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8317 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8319 Cleaned up genPackBits and genUnpackBits and added two helper
8320 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8321 for literal assignments in genPackBits (thanks to Frieder for
8327 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8329 Fixed bug #748310 (pointer to function type mishandled when the
8330 function name is omitted). Also fixed a SIGSEGV when a function
8331 attribute (reentrant, etc) is used on a non-function or on a
8332 function but misplaced before the parameter list.
8334 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8336 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8337 * support/Util/SDCCerr.h,

8359 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8361 Made the constant following the "interrupt" keyword optional. If
8362 omitted, the function will not automatically be given an entry
8363 in the interrupt vector table (similar to #pragma NOIV, but
8364 less syntacticly kludgy). The interrupt number is also now
8365 range checked. Also fixed a bug in the high order bit example

8379 * src/SDCCicode.c (operandOperation): rewritten some ops
8380 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8381 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8383 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8384 be re-activated by defining REDUCE_LITERALS)
8385 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8386 unsigned, but are signed by default
8387 * src/SDCCval.c (constVal): rearranged
8388 * src/SDCCval.c (valMod): preliminary fix
8389 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8432 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8433 * src/SDCCval.c (valDiv, valMod): fixed signdness
8434 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8435 signedness of modulo, left and right shift

8895 added if/endif conditional macros to remove options help
8896 messages from optionsTable when a port is not configured, added
8897 support for the PIc16 port in the ports table, when executing
8898 the compiler with no port specified on command line, a default
8899 port is selected with the new macro DEFAULT_PORT which is
8900 defined in port.h, in setDefaultOptions() linkOptions is removed
8901 from initialization assignment, since now it is a set,
8902 parseCmdLine uses setParseWithComma for linkOptions, in
8903 linkEdit() linkOptions are accessed with new function indexSet()
8904 which returns the i'th item of a set variable. See SDCCset.c, in
8905 linkEdit() when calling buildCmdLine(), added linkOptions as
8906 last argument. Now users can pass arguments to gplink via the
8907 -Wl option, main() uses pic16glue() to glue up pic16 programs

8921 gpasm complaining and test the linkage with gplink, _linkCmd and
8922 _asmCmd changed to be more gplink and gpasm friendly
8923 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8924 produced an error when parsed, peep rule 12 is added to utilize
8925 movff, but it is commented out since the pCode does not support
8926 yet a command with 2 address arguments
8928 2003-05-18 <johan AT balder>
8930 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8957 2003-05-11 Borut Razem <borut.razem AT siol.net>
8959 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9963 2003-01-06 <johan AT balder>
9965 * src/SDCCicode.c: fixed array add
9967 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9968 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9969 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9971 2003-01-04 <johan AT balder>
9973 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9975 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9976 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9978 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9979 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9980 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9982 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9983 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9985 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9986 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9988 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9989 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9991 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9993 * in \sdcc\as\mcs51\ changed these files in order to create an
9994 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9995 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9996 following files to include the previous two files: aslink.dsp,
9997 Makefile.aslink, Makefile.bcc, and Makefile.in.
9999 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10000 .adb instead of .cdb
10002 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10004 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10005 value from option --iram-size.
10007 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10009 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10012 2002-09-18 <wiml AT hhhh.org>
10014 * SDCClrange.h: exposed setFromRange() and setToRange()
10015 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10016 packRegsForAccUse() (bug 542397)
10017 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10018 multiple times and emitting the fetch operations more than once
10019 added aopGetUsesAcc() function to allow binary operators to
10020 fetch their operands in the correct order; made genMinus() emit
10021 compact code for X = LITERAL - Y
10023 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10024 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10025 sprintf() in line 1267.
10027 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10028 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10031 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10032 Changes to aslink (All the changes are marked with 'JCF'):
10034 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10037 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10038 area BSEG. Also moves, if possible, the DATA area down into the internal
10039 ram so more space is available.
10041 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10044 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10045 not bytes. Function summary() which creates a memory usage summary
10046 file with extension .mem. Reports of overlaping stack and small stack
10047 size. If the space for the stack is less than 16 bytes aslink trows a
10050 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10051 the 8051. Option 'y' for memory summary output file.
10053 Changes to sdcc (All the changes are marked with 'JCF'):
10055 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10057 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10058 overlaying area for it (uses RegBankUsed[4]).
10060 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10061 bank zero as used by default. By default aslink locates the stack
10062 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10063 the creation of the .mem file. Delegates the allocation of data area
10064 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10065 the begining of the stack area to aslink.
10067 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10068 glue() in SDCCglue.c creates an area for it.
10070 2002-09-03 Borut Razem <borut.razem AT siol.net>
10071 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10072 sdcc/src/pic/glue.c:
10073 introduced atexit() handler for teporay files removal in case of
10074 errors, assertions, ...
10076 2002-08-29 Borut Razem <borut.razem AT siol.net>
10077 * sdcc/support/cpp2/auto-host_vc_in.h:
10078 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10079 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10080 Maybe there is a similar problem with BORLANDC? It should be checked!
10082 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10083 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10084 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10085 was not executed, and the compiler (cl) launched a warning:
10086 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10088 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10089 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10091 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10092 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10094 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10095 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10096 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10097 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10098 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10099 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10100 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10101 - added Release configuration in VS projects
10102 - review of compiler an linker options
10103 - VC .exe files are generated in bin_vc directory, not to interfere
10104 with binaries generated from other projects (cygwin, mingw, bcc ...)
10106 * sdcc/src/yacc.dsp: added
10108 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10109 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10110 and insert the version number definitions from .version
10112 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10114 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10115 added - genarate auto-host.h using auto-host_vc_in.h as template
10118 removed from CVS, generated automatically
10120 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10121 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10123 2002-08-11 Borut Razem <borut.razem AT siol.net>
10124 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10126 2002-08-10 Borut Razem <borut.razem AT siol.net>
10127 * src/SDCCmain.c (main):
10128 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10129 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10130 The consequence was that some temporary files were not removed.
10133 unification of code in functions tempfilename() and tempfile():
10134 function tempnam() is defined in Visual Studio 6.0 and .NET
10136 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10138 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10139 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10140 - removed compiler command line option /WX: Treats all warnings as errors
10141 - update a list of source files, included into the project
10143 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10144 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10145 changed project type to Generic Project so that can be correcly converted to VS.NET project
10147 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10149 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10151 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10153 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10154 added return 0 statements after assert() to make compiler happy
10156 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10157 added newline in the def file to keep MSC compiler satisfied
10159 * sdcc/src/z80/gen.c:
10160 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10161 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10162 - solved MSC error in function aopDump()
10164 * sdcc_vc.h: define PREFIX as "\\sdcc"
10166 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10167 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10170 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10171 - Rewrote the register banking algorithm.
10172 - Added pCode live-range analysis to registers (for now, only non-used and
10173 singly-used registers optimized away)
10175 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10177 * 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.

10202 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10204 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10206 2002-03-28 Johan Knol <johan AT balder>
10208 * src/SDCCval.c: fixed bug #532436
10210 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10212 Added "char *Processor" field to the port structure.
10215 Added -p option. Allows port dependent processor to be specified.
10218 Initialized the new field char *Processor field to NULL in all ports
10221 Compiler generated registers for interrupt context saving
10222 were not getting allocated.
10224 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10227 Fixed left shift. Will promote the left side of a left shift
10228 if a) left shifting more than size of operand or b) when assigned
10229 to something size > size of left side
10231 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10233 tons of changes. Register allocation has been
10234 rewritten. Added customization for the various PICs. Flow
10235 analysis is restructured. ...
10237 * src/pic/device.h:
10240 * src/pic/device.c:
10241 Added. device.c is a PIC port hack to accomodate variations
10244 2002-03-13 Michael Hope <michaelh AT vroom>
10246 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10248 2002-03-04 johanknol <johanknol AT manik>
10250 * /src/SDCCval.c: fixed
10252 const unsigned char arr[][2] = { { 0, 1 } };

10339 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10341 * sdcc/src/SDCCloop.c:
10342 Previous fix was not good. basic blocks that have "break" or "return" are
10343 not really partof a loop , but live ranges used in these blocks should
10344 be live thru the entire loop, so set partOfLoop but don't add them to
10347 2002-02-21 <johan AT FRIJA>
10349 * src/SDCCcse.c: fixed bug #514308
10351 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10354 Fixed BUG #519583. If a conditional block ended in a return/break
10355 statement inside a loop, it was not being considered part of the loop.
10357 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10359 2002-02-10 Karl Bongers <karl AT turbobit.com>

10368 * device/examples/Makefile, examples/test3.c:
10369 Add Makefile in device/examples folder, compiles test3.c
10370 for use as a multiple module SDCDB test case.
10372 * sim/ucsim/cmd.src/cmdset.cc:
10373 Took out debug printfs in ucsim "next" command.
10375 * sim/ucsim/xa.src:
10376 Karl and Johan start ucsim XA support. Most dissassembly working,
10377 about 75% emulation done(plenty of work remaining).
10379 * sim/ucsim/z80.src:
10380 Add Z80 support to ucsim, add test-ucz80 regression test,
10381 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10382 Notice z80 compiler fails on examples/test3.c/crc code.
10384 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

10398 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10399 1) handle multiple send & receives from register bank1
10400 2) ralloc can now allocate DPTR1 to some liveRanges
10402 * src/SDCCsymt.c, src/SDCCsymt.h:
10403 changes to handle multiple sends & receives
10405 * src/SDCCptropt.h:
10406 added some pointer arithmetic optimization
10408 * src/SDCCptropt.c:

10410 called from anywhere (will get this working shortly)
10412 * src/SDCCopt.c: fixed for multiple sends & receives
10415 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10416 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10417 set preprocessor defines (depending on options)
10419 * src/SDCCicode.c, src/SDCCicode.h:
10420 changes made to handle multiple sends & receives
10423 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
