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

154 fixes #1469504 and #1474602,
155 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

477 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
478 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

501 2006-03-06 Borut Razem <borut.razem AT siol.net>
503 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
504 made the linker quiet
506 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
508 * src/pic16/gen.c (genPcall): fixed bug #1443644
509 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
510 which dumps before the function entry point a data byte which represents
511 the number of the local variables used by the specified function, added
512 'xinst' for initial support for Extended Instruction Support,
513 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
514 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
515 port->fun_prefix anymore (may change later),

519 (genOr): removed some legacy pic-port instructions,
520 * src/pic16/genarith.c (genAddLit): re-enabled old code because
521 performing operations with SFR's causes data to be written more than

523 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
525 * src/pic16/main.c (_process_pragma): stack bound checking did not take

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

2806 * src/SDCCglobal.h (struct options),
2808 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2809 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2810 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2811 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2812 always available in leading double underscore form. The C99 support is
2813 mostly missing, but it's a start.
2814 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2815 reserved identifier "__data".

2891 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2893 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2895 * device/lib/printf_large.c: removed inline assembly for portability and
2896 readability. Use printf_fast if speed or size are more important.
2897 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2898 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2900 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2902 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2903 prevent compiler warning
2905 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2907 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2908 moved to level 0 and declared as static. Also they are explicit
2909 placed in access bank. This was necessery because some times they
2910 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2911 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2912 optimizations. Currently only compare to unsigned char is implemented,
2913 * src/pic16/gen.c: added fReturnIdx array,
2914 * (struct resolvedIfx) is moved to gen.h and made public,
2915 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2916 * (aopForSym): added an optimization to directly store in stack of
2917 the operand of a SEND iCode,
2918 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2919 but as registers instead (AOP_REG) using the fReturnIdx array,
2920 * (pic16_freeAsmop): remove the freed register from the
2921 _G.sregsAlloc field,
2922 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2923 a compare of 'WREG',
2924 * (pic16_popGetTempRegCond): changed function prototype, now
2925 function takes also a bitVector argument v which holds the current
2926 set of registers that are allocated for stack access by aopForSym,
2927 registers allocated in aopForSym for accessing stack symbols are not
2928 any more part of the functions usedRegs field,
2929 * (genCall): some times aopOp is called for a stack variable to be
2930 send, aopForSym might perform the push, if this is true make sure
2931 that genCall doesn't push the variable twice by testing _G.resDirect,
2932 * (genFunction): changed testing for unspecified interrupt number
2933 from 256 to INTNO_UNSPEC,
2934 * modified selection scheme of frame pointer generation. Previously
2935 if function did use local registers a frame pointer was generated,
2936 now a frame pointer is generated only if function has arguments
2937 (that need PLUSW2 register access), or has stack arguments, or the
2938 compiler is not instructed to omit the frame pointer,
2939 * (genEndFunction): before restoring local registers that were saved
2940 in the function preamble, also restore the registers that *might*
2941 have been allocated for stack access,
2942 * (genRet): removed some old comments,
2943 * (genCmp, the active (RN's) version): added a call to the
2944 pic16_genCmp_special function to perform the compare with a more
2945 robust and optimized way,
2946 * (genInline): a feature has been added in inline code generation,
2947 which allows a wildcard variable substitution when writing inline
2948 assembly. Code is incomplete and experimental therefore undocumented,
2949 * (genCast): changed order of aopOp for result and right to allow
2950 aopForSym to directly load the result if possible,
2951 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2952 perform an optimized compare on some selected special occasions,
2953 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2954 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2955 generate an IVT any more,
2956 * src/pic16/main.c (pic16_optionsTable): added command line option
2958 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2959 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2961 * src/pic16/NOTES: Raphael Neider added in list of active developers
2962 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2963 jumptable_end to prevent bug #,
2964 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2965 inCond and outCond fields,
2966 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2967 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2968 turn off register spilling,
2969 * (packRegsForOneUse): synced with other ports' versions although it
2970 is not used currently,
2971 * (pic16_packRegisters): added an optimization while reading
2972 structure bitfields, some registers may be saved (malloc code is
2973 decreased by 80 bytes)
2975 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2977 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2978 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2979 this can be optimized more?
2981 2005-03-10 Raphael Neider <rneider AT web.de>
2983 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2984 genNearPointerGet): (hopefully) fixed access to bitfields via
2985 pointers (p->bitN = x; and x = p->bitN; failed)
2987 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2989 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3619 Adding support for replacing ljmps with sjmps in jumptables
3620 generated for switch statements. For now you need to set the
3621 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3622 Now 4 algorithms for mcs51 jumptable generation are used:
3623 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3624 addresses loaded pc-relative for up to 112 cases and stack-pushing
3625 target addresses loaded with offset from dptr for up to 256 cases.

3655 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3657 * added libc directory. The current version of LibC contains string
3658 functions, ctype functions and macros and some functions of the
3659 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3660 be extensively tested in the future. Standard disclaimer here.
3661 Library is not automatically build yet. But one can build it by
3662 invoking 'make' inside the libc directory.

3673 * (pic16_storeForReturn): optimized return of 0,
3674 * (genCmp): experimental code for new genCmp which uses PIC18's
3675 special compare&skip instructions. Initial tests fail some times
3676 with variables grater than 1 byte in size, so new code is disabled,
3677 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3679 * (genCast): began a fix to optimize the casting of a bit to another
3680 bit, now assigning a bitfield to another bitfield will fail, sorry,

3689 and 1 for banking instruction,
3690 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3691 caused stop processing pCodes after a inline assembly block,
3692 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3693 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3694 registers when it shouldn't,
3695 * src/pic16/ralloc.c (allocReg): add preliminary support for
3696 supporting a limited set of temporary registers,
3698 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3700 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3704 (genFunction): optimize RECEIVE iCodes in reentrant functions
3706 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6705 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6706 loaded with the linker search paths (-L arguments) and the libraries
6707 to be linked with the current source (-l arguments). Changes
6708 currently will affect only the pic16 port.
6709 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6710 include path the port specific paths and port specific libraries,
6711 * gplink command now contains the $3 argument,
6712 * src/pic16/device.h,
6713 * src/pic16/device.c,: structure PIC_device is made public and

6729 Documenting changes from previous commits.
6730 * configure.in (version 1.56),
6731 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6732 when generating output files to configure the pic16 library,
6733 but now I've commented it out, since gputils aren't installed in the
6734 SF compile farm, so library won't compile
6736 * device/lib/Makefile.in (version 1.56): initially I've added in
6737 target 'all' the prerequestive 'model-pic16' so it compiled the
6738 pic16 library, but now I've commented it out for the same reasons
6740 * added targets 'model-pic16' and 'objects-pic16' to compile the
6742 * added target 'port-specific-objects-pic16' to handle the
6743 generated libraries and copy them into the build/ directory
6744 * added target 'clean-intermediate-pic16' to clean intermediate
6745 files into pic16 directory
6746 * in target 'installdirs' added line to create directory pic16 in

7039 PIC16 port related changes:
7040 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7041 added variable stackPos,
7043 * gen.c: genCall, assignResultValue: added support for
7044 pushing/retrieving function parameters to/from stack,
7045 genFunction,genEndFunction: setup stack frame for the
7047 genAddrOf: will be changed according to bug 863624
7049 * added files genutils.c and genutils.h which contain gen*
7050 debugged and optimised functions extracted from gen.c
7052 * glue.c: added variable 'externs' which holds extern symbols,
7053 pic16emitRegularMap: is modified to properly handle relocatable
7054 symbols under the new scheme,
7055 pic16createInterruptVect: is modified
7056 pic16printPublics: is modified to emit 'global' assembler directives,
7057 added pic16_printExterns to print extern symbols,
7058 pic16glue: initializes stack/frame pointer in the beginning of
7059 the assembly output. Temporary hack, will be corrected later,
7060 because gplink yet does not support stack and SDCC does not
7061 yet support a type of crt0.o object to create the final binary.
7063 * Removed many lines that contain 8051 legacy code.
7064 * The code is finally placed under a 'code' directive.
7065 * Added port specific options.
7067 * _process_pragma: simplified since now we do not need *special*
7068 include file to define SFR registers. But a separate header
7069 will be needed. This will be developed later.
7070 * _pic16_parseOptions: added, parses port specific options:
7071 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7072 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7073 --preplace-udata-with=
7075 * _pic16_setDefaultOptions: modified to initialize section names,
7076 but hack is temporarly out of order since it needs improvement.
7077 * _pic16_genAssemblerPreamble: configuration words are emitted by
7078 their address instead of their name. This part is incomplete and
7079 supports only the 18Fxx2 devices. Other devices will emit an error
7080 during assembly since they do not contain the same set of config
7082 * _pic16_genIVT: is modified,
7084 * pcode.c: added definitions for some hardware registers that are needed
7086 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7087 All PCI entries are updated. Now LFSR is supported.
7088 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7089 * added pic16_newpCodeOpLit2 to support instructions with
7090 two literal arguments
7091 * pic16_pCode2str: corrected code that emits assembler instructions
7092 with two literal operands and those that have an access bit modifier
7093 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7094 this fixes a bug which caused some labels to be lost, when an
7095 assembler directive was added, i.e. banksel,
7096 * pic16_FixRegisterBanking: improved logic that causes the insertion
7098 * InlineFunction: functions that are called once, are not any more
7099 inlined. This can be a port option in the future,
7101 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7103 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7104 hold the corresponding uninitialized symbols,
7105 * pic16_allocProcessorRegister: registers have explicit marked the
7107 * pic16_allocInternalRegister: registers are explicit marked as
7109 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7110 processing list, so bit registers were lost,
7113 * ralloc.h: added field 'accessBank' and original symbol operand
7114 in register definition,
7115 * removed the field isMapped from register definition,
7117 ** Several functions have been removed from various sources:
7118 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7119 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7120 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7121 pic16_assignRelocatableRegisters
7123 ** others have been introduced:
7124 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7125 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7127 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7129 * support/scripts/inc2h.pl: changed definition of BIT_AT
7130 to emit 'sbit at' instead of 'bit at'. This was a request.
7132 PIC16 port related preliminary changes:
7133 * gen.c: prefixed function popRegFromString with
7134 pic16_ and all references to it corrected
7135 * pcode.c: all pic16_pc_* hardware registers prefixed
7136 with underscore (_),
7137 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7138 * ralloc.c: newReg(): when register is REG_SFR then
7139 set address to rIdx,
7140 pic16_allocProcessorRegister(): marks register wasUsed=0
7141 pic16_writeUsedRegs(): added a call to assign processor
7142 registers via pic16_assignFixedRegisters
7144 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7146 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7147 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7148 variables in unused register banks. Also the SSEG is placed
7149 wherever there is enough space for it, and IDATA can be anywhere
7150 in internal RAM. For now compile using -Wl-Y[stack_size].
7151 The mem file is different for this option as well, since it
7152 makes no sense of talking about DSEG lenght.
7154 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7156 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7157 in certain cases, e.g. when ROM assignment, patch provided
7158 from Albert den Haan.
7160 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7399 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7401 * src/SDCCast.c (decorateType): disabled a transformation I added in
7402 revision 1.188 (access to fields of a structure at an absolute address);
7403 it breaks with bitfields, extern declarations, and gcse analysis.
7404 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7405 could be assigned through a pointer, so don't complain.
7406 * src/SDCCast.c (astErrors),
7408 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8046 support for standard C idiom of memory mapped variables; for
8047 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8048 to xdata int at 0x1234 tempvar = 1.
8049 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8050 provided by Akiya ISHIDA

8066 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8068 Fixed bug #621531 (const & volatile confusion in the type chain).
8069 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8070 refer to the const or volatile state of the pointer itself.

8135 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8136 pcoderegs.h, ralloc.c, ralloc.h
8137 * main.c: added top header and GPL license notice

8161 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8162 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8163 fetching of the pointer
8164 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8165 copied from genNearPointerSet()
8166 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8167 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8168 If they pop r0/r1 they must be called in the opposite order than aopOp().
8169 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8170 (resp. --stack-auto), prepared for --xstack

8181 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8183 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8184 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8185 type for bits was changed. It resulted in bit variables becoming
8186 global, which is not permitted in PIC 14 assembly output.
8188 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8190 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8203 A few small changes that speed up the peephole optimizer.
8207 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8209 Try to make the peephole optimizer smarter by maintaining
8210 an association between the assembly source code and the
8211 iCodes that originated them. Put this information to use
8212 with a new peephole rule condition "notVolatile" so that
8213 the rules can be aggressive yet still safe.
8218 * src/mcs51/peeph.def
8220 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8224 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8225 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8226 if the left or right operand symbols have the accuse flag set.
8228 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8230 Changed the type of the result of the ! (NOT) operator to char;
8231 previously it returned the same type as the source. This allows
8232 us to eliminate all the genFloatNot functions (all of its target
8233 implementations were very buggy) since !float can use the same
8236 * src/SDCCicode.c (ast2iCode): ! returns char

8238 * src/ds390/gen.c (genNot, genNotFloat),
8239 * src/z80/gen.c (genNot, genNotFloat),
8240 * src/pic/gen.c (genNot, genNotFloat),

8245 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8246 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8247 during interrupts. Ensure WSAVE is located at a shared bank address.
8248 2. Fixed page selection in some places
8249 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8250 the registers name strings.
8251 4. Fixed "signed / unsigned compare" compiler warnings.
8252 5. The PIC port manages its own allocation of the general purpose
8253 registers, but makes no attempt to reuse them. As a result when
8254 compiling it soon runs out of general purpose registers. Some
8255 additional code was added to the files pcode.c and device.c to walk
8256 through the function call tree and rename the registers so that they
8266 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8267 genPlus() & genMinus() when the result is the same as left or right
8269 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8273 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8275 Made bitfield a distinct type from bit so that bitfields
8276 convert as per ANSI C and bits retain their traditional
8277 boolean style behaviour. Implemented bitfield support in
8285 * src/ds390/gen.c: bit v bitfield split
8286 * src/z80/gen.c: New support for bitfields
8287 * support/regression/tests/bitfields.c: reenabled z80,
8290 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8292 Rules 246.x, 247.x relate to bitfields, the others speed up
8293 access to xdata mapped I/O devices.
8295 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8297 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8299 Cleaned up genPackBits and genUnpackBits and added two helper
8300 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8301 for literal assignments in genPackBits (thanks to Frieder for
8307 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8309 Fixed bug #748310 (pointer to function type mishandled when the
8310 function name is omitted). Also fixed a SIGSEGV when a function
8311 attribute (reentrant, etc) is used on a non-function or on a
8312 function but misplaced before the parameter list.
8314 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8316 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8317 * support/Util/SDCCerr.h,
8318 * support/Util/SDCCerr.c: Added func attr misuse error msg
8320 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8322 Fixed bug #787649 by anonymous
8323 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8339 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8341 Made the constant following the "interrupt" keyword optional. If
8342 omitted, the function will not automatically be given an entry
8343 in the interrupt vector table (similar to #pragma NOIV, but
8344 less syntacticly kludgy). The interrupt number is also now
8345 range checked. Also fixed a bug in the high order bit example

8353 * support/Util/SDCCerr.h
8356 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8358 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8359 * src/SDCCicode.c (operandOperation): rewritten some ops
8360 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8361 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8363 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8364 be re-activated by defining REDUCE_LITERALS)
8365 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8366 unsigned, but are signed by default
8367 * src/SDCCval.c (constVal): rearranged
8368 * src/SDCCval.c (valMod): preliminary fix
8369 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8411 constants are unsigned; added recognition of "u" flag for unsigned
8412 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8413 * src/SDCCval.c (valDiv, valMod): fixed signdness
8414 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8415 signedness of modulo, left and right shift

8875 added if/endif conditional macros to remove options help
8876 messages from optionsTable when a port is not configured, added
8877 support for the PIc16 port in the ports table, when executing
8878 the compiler with no port specified on command line, a default
8879 port is selected with the new macro DEFAULT_PORT which is
8880 defined in port.h, in setDefaultOptions() linkOptions is removed
8881 from initialization assignment, since now it is a set,
8882 parseCmdLine uses setParseWithComma for linkOptions, in
8883 linkEdit() linkOptions are accessed with new function indexSet()
8884 which returns the i'th item of a set variable. See SDCCset.c, in
8885 linkEdit() when calling buildCmdLine(), added linkOptions as
8886 last argument. Now users can pass arguments to gplink via the
8887 -Wl option, main() uses pic16glue() to glue up pic16 programs

8901 gpasm complaining and test the linkage with gplink, _linkCmd and
8902 _asmCmd changed to be more gplink and gpasm friendly
8903 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8904 produced an error when parsed, peep rule 12 is added to utilize
8905 movff, but it is commented out since the pCode does not support
8906 yet a command with 2 address arguments
8908 2003-05-18 <johan AT balder>
8910 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8937 2003-05-11 Borut Razem <borut.razem AT siol.net>
8939 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8940 the path of bin directory, so that PATH is the only env. variable, which has to be set
8941 in case of standard installation.

9962 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9963 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9965 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9966 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9968 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9969 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9971 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9973 * in \sdcc\as\mcs51\ changed these files in order to create an
9974 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9975 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9976 following files to include the previous two files: aslink.dsp,
9977 Makefile.aslink, Makefile.bcc, and Makefile.in.
9979 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9980 .adb instead of .cdb
9982 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9984 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9985 value from option --iram-size.
9987 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9989 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9992 2002-09-18 <wiml AT hhhh.org>
9994 * SDCClrange.h: exposed setFromRange() and setToRange()
9995 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9996 packRegsForAccUse() (bug 542397)
9997 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9998 multiple times and emitting the fetch operations more than once
9999 added aopGetUsesAcc() function to allow binary operators to
10000 fetch their operands in the correct order; made genMinus() emit
10001 compact code for X = LITERAL - Y
10003 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10004 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10005 sprintf() in line 1267.
10007 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10008 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10011 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10012 Changes to aslink (All the changes are marked with 'JCF'):
10014 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10017 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10018 area BSEG. Also moves, if possible, the DATA area down into the internal
10019 ram so more space is available.
10021 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10024 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10025 not bytes. Function summary() which creates a memory usage summary
10026 file with extension .mem. Reports of overlaping stack and small stack
10027 size. If the space for the stack is less than 16 bytes aslink trows a
10030 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10031 the 8051. Option 'y' for memory summary output file.
10033 Changes to sdcc (All the changes are marked with 'JCF'):
10035 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10037 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10038 overlaying area for it (uses RegBankUsed[4]).
10040 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10041 bank zero as used by default. By default aslink locates the stack
10042 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10043 the creation of the .mem file. Delegates the allocation of data area
10044 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10045 the begining of the stack area to aslink.
10047 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10048 glue() in SDCCglue.c creates an area for it.
10050 2002-09-03 Borut Razem <borut.razem AT siol.net>
10051 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10052 sdcc/src/pic/glue.c:
10053 introduced atexit() handler for teporay files removal in case of
10054 errors, assertions, ...
10056 2002-08-29 Borut Razem <borut.razem AT siol.net>
10057 * sdcc/support/cpp2/auto-host_vc_in.h:
10058 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10059 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10060 Maybe there is a similar problem with BORLANDC? It should be checked!
10062 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10063 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10064 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10065 was not executed, and the compiler (cl) launched a warning:
10066 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10068 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10069 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10071 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10072 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10074 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10075 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10076 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10077 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10078 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10079 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10080 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10081 - added Release configuration in VS projects
10082 - review of compiler an linker options
10083 - VC .exe files are generated in bin_vc directory, not to interfere
10084 with binaries generated from other projects (cygwin, mingw, bcc ...)
10086 * sdcc/src/yacc.dsp: added
10088 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10089 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10090 and insert the version number definitions from .version
10092 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10094 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10095 added - genarate auto-host.h using auto-host_vc_in.h as template
10098 removed from CVS, generated automatically
10100 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10101 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10103 2002-08-11 Borut Razem <borut.razem AT siol.net>
10104 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10106 2002-08-10 Borut Razem <borut.razem AT siol.net>
10107 * src/SDCCmain.c (main):
10108 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10109 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10110 The consequence was that some temporary files were not removed.
10113 unification of code in functions tempfilename() and tempfile():
10114 function tempnam() is defined in Visual Studio 6.0 and .NET
10116 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10118 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10119 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10120 - removed compiler command line option /WX: Treats all warnings as errors
10121 - update a list of source files, included into the project
10123 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10124 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10125 changed project type to Generic Project so that can be correcly converted to VS.NET project
10127 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10129 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10131 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10133 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10134 added return 0 statements after assert() to make compiler happy
10136 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10137 added newline in the def file to keep MSC compiler satisfied
10139 * sdcc/src/z80/gen.c:
10140 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10141 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10142 - solved MSC error in function aopDump()
10144 * sdcc_vc.h: define PREFIX as "\\sdcc"
10146 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10147 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10150 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10151 - Rewrote the register banking algorithm.
10152 - Added pCode live-range analysis to registers (for now, only non-used and
10153 singly-used registers optimized away)
10155 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10157 * 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.

10182 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10184 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10186 2002-03-28 Johan Knol <johan AT balder>
10188 * src/SDCCval.c: fixed bug #532436
10190 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10192 Added "char *Processor" field to the port structure.
10195 Added -p option. Allows port dependent processor to be specified.
10198 Initialized the new field char *Processor field to NULL in all ports
10201 Compiler generated registers for interrupt context saving
10202 were not getting allocated.
10204 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10207 Fixed left shift. Will promote the left side of a left shift
10208 if a) left shifting more than size of operand or b) when assigned
10209 to something size > size of left side
10211 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10215 analysis is restructured. ...
10217 * src/pic/device.h:
10220 * src/pic/device.c:
10221 Added. device.c is a PIC port hack to accomodate variations
10224 2002-03-13 Michael Hope <michaelh AT vroom>
10226 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10228 2002-03-04 johanknol <johanknol AT manik>
10230 * /src/SDCCval.c: fixed
10232 const unsigned char arr[][2] = { { 0, 1 } };

10319 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10321 * sdcc/src/SDCCloop.c:
10322 Previous fix was not good. basic blocks that have "break" or "return" are
10323 not really partof a loop , but live ranges used in these blocks should
10324 be live thru the entire loop, so set partOfLoop but don't add them to
10327 2002-02-21 <johan AT FRIJA>
10329 * src/SDCCcse.c: fixed bug #514308
10331 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10334 Fixed BUG #519583. If a conditional block ended in a return/break
10335 statement inside a loop, it was not being considered part of the loop.
10337 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10339 2002-02-10 Karl Bongers <karl AT turbobit.com>

10395 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10396 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10397 set preprocessor defines (depending on options)
10399 * src/SDCCicode.c, src/SDCCicode.h:
10400 changes made to handle multiple sends & receives
