119 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
121 Enabled VPATH feature: changed nearly all Makefiles (149 files).
122 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
124 One basic decision: e.g. src/clean.mk includes further files. In order
125 to make this work there are two solutions:
126 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
127 run configure on them. This way they can use
128 'include $(srcdir)/port-clean.mk'
129 - always include clean.mk by the Makefile at the same level. To avoid
130 that `make clean` tries to include and build Makefile.dep the
131 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
132 implemented, because now even `make uninstall` doesn't create
133 Makefile.in. clean.mk could be eliminated by pasting it in
136 * debugger/mcs51/Makefile.in: build own objects from library sources
137 (SLIB, SDCC) in current directory
139 * configure, configure.in: renamed --disable-device-lib-build in
140 --disable-device-lib; added --enable-doc, the required tools are
141 searched by configure; added result message; the toolchain for the
142 belonging ports are now only built, if the port is enabled.
144 * support/regression/*: all output is written in directory gen, because
145 the fwk and ports directories don't livet in the build tree using vpath
147 * doc/sdccman.lyx: renamed --disable-device-lib-build to
148 --disable-device-lib, added --enable-doc, added section VPATH
150 * sim/ucsim/configure.in,
151 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
152 z80 are enabled by default
154 2006-04-24 Raphael Neider <rneider AT web.de>
156 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
157 to config word, "pic14_"-prefixed some extern functions
158 (pic14_emitConfigWord): emit __config directive(s) if assignment to
159 config word has been found
160 * src/pic/device.h: added prototypes
161 * src/pic/pcode.c: added "pic14_"-prefix where needed
162 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
164 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

179 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

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

2832 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2833 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2834 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2835 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2836 always available in leading double underscore form. The C99 support is
2837 mostly missing, but it's a start.
2838 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2839 reserved identifier "__data".
2841 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2915 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2917 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2919 * device/lib/printf_large.c: removed inline assembly for portability and
2920 readability. Use printf_fast if speed or size are more important.
2921 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2922 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2924 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2926 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2927 prevent compiler warning
2929 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2931 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2932 moved to level 0 and declared as static. Also they are explicit
2933 placed in access bank. This was necessery because some times they
2934 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2935 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2936 optimizations. Currently only compare to unsigned char is implemented,
2937 * src/pic16/gen.c: added fReturnIdx array,
2938 * (struct resolvedIfx) is moved to gen.h and made public,
2939 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2940 * (aopForSym): added an optimization to directly store in stack of
2941 the operand of a SEND iCode,
2942 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2943 but as registers instead (AOP_REG) using the fReturnIdx array,
2944 * (pic16_freeAsmop): remove the freed register from the
2945 _G.sregsAlloc field,
2946 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2947 a compare of 'WREG',
2948 * (pic16_popGetTempRegCond): changed function prototype, now
2949 function takes also a bitVector argument v which holds the current
2950 set of registers that are allocated for stack access by aopForSym,
2951 registers allocated in aopForSym for accessing stack symbols are not
2952 any more part of the functions usedRegs field,
2953 * (genCall): some times aopOp is called for a stack variable to be
2954 send, aopForSym might perform the push, if this is true make sure
2955 that genCall doesn't push the variable twice by testing _G.resDirect,
2956 * (genFunction): changed testing for unspecified interrupt number
2957 from 256 to INTNO_UNSPEC,
2958 * modified selection scheme of frame pointer generation. Previously
2959 if function did use local registers a frame pointer was generated,
2960 now a frame pointer is generated only if function has arguments
2961 (that need PLUSW2 register access), or has stack arguments, or the
2962 compiler is not instructed to omit the frame pointer,
2963 * (genEndFunction): before restoring local registers that were saved
2964 in the function preamble, also restore the registers that *might*
2965 have been allocated for stack access,
2966 * (genRet): removed some old comments,
2967 * (genCmp, the active (RN's) version): added a call to the
2968 pic16_genCmp_special function to perform the compare with a more
2969 robust and optimized way,
2970 * (genInline): a feature has been added in inline code generation,
2971 which allows a wildcard variable substitution when writing inline
2972 assembly. Code is incomplete and experimental therefore undocumented,
2973 * (genCast): changed order of aopOp for result and right to allow
2974 aopForSym to directly load the result if possible,
2975 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2976 perform an optimized compare on some selected special occasions,
2977 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2978 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2979 generate an IVT any more,
2980 * src/pic16/main.c (pic16_optionsTable): added command line option
2982 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2983 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2985 * src/pic16/NOTES: Raphael Neider added in list of active developers
2986 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2987 jumptable_end to prevent bug #,
2988 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2989 inCond and outCond fields,
2990 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2991 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2992 turn off register spilling,
2993 * (packRegsForOneUse): synced with other ports' versions although it
2994 is not used currently,
2995 * (pic16_packRegisters): added an optimization while reading
2996 structure bitfields, some registers may be saved (malloc code is
2997 decreased by 80 bytes)
2999 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3001 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3002 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3003 this can be optimized more?
3005 2005-03-10 Raphael Neider <rneider AT web.de>
3007 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3008 genNearPointerGet): (hopefully) fixed access to bitfields via
3009 pointers (p->bitN = x; and x = p->bitN; failed)
3011 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3013 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3015 2005-03-09 Raphael Neider <rneider AT web.de>
3017 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
3019 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3021 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC

3643 Adding support for replacing ljmps with sjmps in jumptables
3644 generated for switch statements. For now you need to set the
3645 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3646 Now 4 algorithms for mcs51 jumptable generation are used:
3647 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3648 addresses loaded pc-relative for up to 112 cases and stack-pushing
3649 target addresses loaded with offset from dptr for up to 256 cases.

3679 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3681 * added libc directory. The current version of LibC contains string
3682 functions, ctype functions and macros and some functions of the
3683 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3684 be extensively tested in the future. Standard disclaimer here.
3685 Library is not automatically build yet. But one can build it by
3686 invoking 'make' inside the libc directory.

3697 * (pic16_storeForReturn): optimized return of 0,
3698 * (genCmp): experimental code for new genCmp which uses PIC18's
3699 special compare&skip instructions. Initial tests fail some times
3700 with variables grater than 1 byte in size, so new code is disabled,
3701 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3703 * (genCast): began a fix to optimize the casting of a bit to another
3704 bit, now assigning a bitfield to another bitfield will fail, sorry,

3713 and 1 for banking instruction,
3714 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3715 caused stop processing pCodes after a inline assembly block,
3716 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3717 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3718 registers when it shouldn't,
3719 * src/pic16/ralloc.c (allocReg): add preliminary support for
3720 supporting a limited set of temporary registers,
3722 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3724 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3728 (genFunction): optimize RECEIVE iCodes in reentrant functions
3730 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3732 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6730 loaded with the linker search paths (-L arguments) and the libraries
6731 to be linked with the current source (-l arguments). Changes
6732 currently will affect only the pic16 port.
6733 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6734 include path the port specific paths and port specific libraries,
6735 * gplink command now contains the $3 argument,
6736 * src/pic16/device.h,

6753 Documenting changes from previous commits.
6754 * configure.in (version 1.56),
6755 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6756 when generating output files to configure the pic16 library,
6757 but now I've commented it out, since gputils aren't installed in the
6758 SF compile farm, so library won't compile
6760 * device/lib/Makefile.in (version 1.56): initially I've added in
6761 target 'all' the prerequestive 'model-pic16' so it compiled the
6762 pic16 library, but now I've commented it out for the same reasons
6764 * added targets 'model-pic16' and 'objects-pic16' to compile the
6766 * added target 'port-specific-objects-pic16' to handle the
6767 generated libraries and copy them into the build/ directory
6768 * added target 'clean-intermediate-pic16' to clean intermediate
6769 files into pic16 directory
6770 * in target 'installdirs' added line to create directory pic16 in

7035 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7036 * src/SDCCsymt.c (newEnumType),
7038 * support/Util/SDCCerr.c,
7039 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7041 * support/regression/tests/enum.c: added test for enum values that
7042 require at least 2 bytes of storage.
7044 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7046 * src/common.h: added ifndef/define/endif macros
7047 around the header file.
7048 Bug reported from Jesus Calvino-Fraga
7050 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7052 * sdcc.spec: updated
7053 * device/include/Makefile.in: don't install CVS directories
7054 * device/lib/Makefile.in: added removal of CVS directories after install
7055 * doc/Makefile: fixed install, added local_icons
7056 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7057 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7058 * src/ds390/gen.c (genRightShift): fixed bug #870788
7059 * src/SDCCast.c (decorateType): fixed bug #870781
7061 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7063 PIC16 port related changes:
7064 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7065 added variable stackPos,
7067 * gen.c: genCall, assignResultValue: added support for
7068 pushing/retrieving function parameters to/from stack,
7069 genFunction,genEndFunction: setup stack frame for the
7071 genAddrOf: will be changed according to bug 863624
7073 * added files genutils.c and genutils.h which contain gen*
7074 debugged and optimised functions extracted from gen.c
7076 * glue.c: added variable 'externs' which holds extern symbols,
7077 pic16emitRegularMap: is modified to properly handle relocatable
7078 symbols under the new scheme,
7079 pic16createInterruptVect: is modified
7080 pic16printPublics: is modified to emit 'global' assembler directives,
7081 added pic16_printExterns to print extern symbols,
7082 pic16glue: initializes stack/frame pointer in the beginning of
7083 the assembly output. Temporary hack, will be corrected later,
7084 because gplink yet does not support stack and SDCC does not
7085 yet support a type of crt0.o object to create the final binary.
7087 * Removed many lines that contain 8051 legacy code.
7088 * The code is finally placed under a 'code' directive.
7089 * Added port specific options.
7091 * _process_pragma: simplified since now we do not need *special*
7092 include file to define SFR registers. But a separate header
7093 will be needed. This will be developed later.
7094 * _pic16_parseOptions: added, parses port specific options:
7095 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7096 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7097 --preplace-udata-with=
7099 * _pic16_setDefaultOptions: modified to initialize section names,
7100 but hack is temporarly out of order since it needs improvement.
7101 * _pic16_genAssemblerPreamble: configuration words are emitted by
7102 their address instead of their name. This part is incomplete and
7103 supports only the 18Fxx2 devices. Other devices will emit an error
7104 during assembly since they do not contain the same set of config
7106 * _pic16_genIVT: is modified,
7108 * pcode.c: added definitions for some hardware registers that are needed
7110 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7111 All PCI entries are updated. Now LFSR is supported.
7112 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7113 * added pic16_newpCodeOpLit2 to support instructions with
7114 two literal arguments
7115 * pic16_pCode2str: corrected code that emits assembler instructions
7116 with two literal operands and those that have an access bit modifier
7117 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7118 this fixes a bug which caused some labels to be lost, when an
7119 assembler directive was added, i.e. banksel,
7120 * pic16_FixRegisterBanking: improved logic that causes the insertion
7122 * InlineFunction: functions that are called once, are not any more
7123 inlined. This can be a port option in the future,
7125 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7127 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7128 hold the corresponding uninitialized symbols,
7129 * pic16_allocProcessorRegister: registers have explicit marked the
7131 * pic16_allocInternalRegister: registers are explicit marked as
7133 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7134 processing list, so bit registers were lost,
7137 * ralloc.h: added field 'accessBank' and original symbol operand
7138 in register definition,
7139 * removed the field isMapped from register definition,
7141 ** Several functions have been removed from various sources:
7142 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7143 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7144 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7145 pic16_assignRelocatableRegisters
7147 ** others have been introduced:
7148 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7149 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7151 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7153 * support/scripts/inc2h.pl: changed definition of BIT_AT
7154 to emit 'sbit at' instead of 'bit at'. This was a request.
7156 PIC16 port related preliminary changes:
7157 * gen.c: prefixed function popRegFromString with
7158 pic16_ and all references to it corrected
7159 * pcode.c: all pic16_pc_* hardware registers prefixed
7160 with underscore (_),
7161 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7162 * ralloc.c: newReg(): when register is REG_SFR then
7163 set address to rIdx,
7164 pic16_allocProcessorRegister(): marks register wasUsed=0
7165 pic16_writeUsedRegs(): added a call to assign processor
7166 registers via pic16_assignFixedRegisters
7168 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7170 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7171 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7172 variables in unused register banks. Also the SSEG is placed
7173 wherever there is enough space for it, and IDATA can be anywhere
7174 in internal RAM. For now compile using -Wl-Y[stack_size].
7175 The mem file is different for this option as well, since it
7176 makes no sense of talking about DSEG lenght.
7178 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7180 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7181 in certain cases, e.g. when ROM assignment, patch provided
7182 from Albert den Haan.

7423 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7425 * src/SDCCast.c (decorateType): disabled a transformation I added in
7426 revision 1.188 (access to fields of a structure at an absolute address);
7427 it breaks with bitfields, extern declarations, and gcse analysis.
7428 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7429 could be assigned through a pointer, so don't complain.
7430 * src/SDCCast.c (astErrors),
7432 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8070 support for standard C idiom of memory mapped variables; for
8071 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8072 to xdata int at 0x1234 tempvar = 1.
8073 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8074 provided by Akiya ISHIDA

8186 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8187 fetching of the pointer
8188 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8189 copied from genNearPointerSet()
8190 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8191 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8207 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8208 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8209 type for bits was changed. It resulted in bit variables becoming
8210 global, which is not permitted in PIC 14 assembly output.
8212 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8214 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8227 A few small changes that speed up the peephole optimizer.
8231 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8233 Try to make the peephole optimizer smarter by maintaining
8234 an association between the assembly source code and the
8235 iCodes that originated them. Put this information to use
8236 with a new peephole rule condition "notVolatile" so that
8237 the rules can be aggressive yet still safe.
8242 * src/mcs51/peeph.def
8244 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8248 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8249 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8250 if the left or right operand symbols have the accuse flag set.
8252 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8254 Changed the type of the result of the ! (NOT) operator to char;
8255 previously it returned the same type as the source. This allows
8256 us to eliminate all the genFloatNot functions (all of its target
8257 implementations were very buggy) since !float can use the same

8269 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8270 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8271 during interrupts. Ensure WSAVE is located at a shared bank address.
8272 2. Fixed page selection in some places
8273 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8274 the registers name strings.
8275 4. Fixed "signed / unsigned compare" compiler warnings.
8276 5. The PIC port manages its own allocation of the general purpose
8277 registers, but makes no attempt to reuse them. As a result when
8278 compiling it soon runs out of general purpose registers. Some
8279 additional code was added to the files pcode.c and device.c to walk
8280 through the function call tree and rename the registers so that they
8290 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8291 genPlus() & genMinus() when the result is the same as left or right

8297 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8299 Made bitfield a distinct type from bit so that bitfields
8300 convert as per ANSI C and bits retain their traditional
8301 boolean style behaviour. Implemented bitfield support in
8309 * src/ds390/gen.c: bit v bitfield split
8310 * src/z80/gen.c: New support for bitfields
8311 * support/regression/tests/bitfields.c: reenabled z80,
8314 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8316 Rules 246.x, 247.x relate to bitfields, the others speed up
8317 access to xdata mapped I/O devices.
8319 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8321 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8323 Cleaned up genPackBits and genUnpackBits and added two helper
8324 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8325 for literal assignments in genPackBits (thanks to Frieder for
8331 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8333 Fixed bug #748310 (pointer to function type mishandled when the
8334 function name is omitted). Also fixed a SIGSEGV when a function
8335 attribute (reentrant, etc) is used on a non-function or on a
8336 function but misplaced before the parameter list.
8338 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8340 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8341 * support/Util/SDCCerr.h,

8363 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8365 Made the constant following the "interrupt" keyword optional. If
8366 omitted, the function will not automatically be given an entry
8367 in the interrupt vector table (similar to #pragma NOIV, but
8368 less syntacticly kludgy). The interrupt number is also now
8369 range checked. Also fixed a bug in the high order bit example

8383 * src/SDCCicode.c (operandOperation): rewritten some ops
8384 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8385 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8387 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8388 be re-activated by defining REDUCE_LITERALS)
8389 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8390 unsigned, but are signed by default
8391 * src/SDCCval.c (constVal): rearranged
8392 * src/SDCCval.c (valMod): preliminary fix
8393 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8899 added if/endif conditional macros to remove options help
8900 messages from optionsTable when a port is not configured, added
8901 support for the PIc16 port in the ports table, when executing
8902 the compiler with no port specified on command line, a default
8903 port is selected with the new macro DEFAULT_PORT which is
8904 defined in port.h, in setDefaultOptions() linkOptions is removed
8905 from initialization assignment, since now it is a set,
8906 parseCmdLine uses setParseWithComma for linkOptions, in
8907 linkEdit() linkOptions are accessed with new function indexSet()
8908 which returns the i'th item of a set variable. See SDCCset.c, in
8909 linkEdit() when calling buildCmdLine(), added linkOptions as
8910 last argument. Now users can pass arguments to gplink via the
8911 -Wl option, main() uses pic16glue() to glue up pic16 programs

8925 gpasm complaining and test the linkage with gplink, _linkCmd and
8926 _asmCmd changed to be more gplink and gpasm friendly
8927 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8928 produced an error when parsed, peep rule 12 is added to utilize
8929 movff, but it is commented out since the pCode does not support
8930 yet a command with 2 address arguments
8932 2003-05-18 <johan AT balder>
8934 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8961 2003-05-11 Borut Razem <borut.razem AT siol.net>
8963 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9967 2003-01-06 <johan AT balder>
9969 * src/SDCCicode.c: fixed array add
9971 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9972 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9973 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9975 2003-01-04 <johan AT balder>
9977 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9979 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9980 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9982 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9983 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9984 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9986 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9987 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9989 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9990 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9992 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9993 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9995 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9997 * in \sdcc\as\mcs51\ changed these files in order to create an
9998 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9999 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10000 following files to include the previous two files: aslink.dsp,
10001 Makefile.aslink, Makefile.bcc, and Makefile.in.
10003 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10004 .adb instead of .cdb
10006 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10008 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10009 value from option --iram-size.
10011 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10013 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10016 2002-09-18 <wiml AT hhhh.org>
10018 * SDCClrange.h: exposed setFromRange() and setToRange()
10019 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10020 packRegsForAccUse() (bug 542397)
10021 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10022 multiple times and emitting the fetch operations more than once
10023 added aopGetUsesAcc() function to allow binary operators to
10024 fetch their operands in the correct order; made genMinus() emit
10025 compact code for X = LITERAL - Y
10027 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10028 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10029 sprintf() in line 1267.
10031 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10032 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10035 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10036 Changes to aslink (All the changes are marked with 'JCF'):
10038 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10041 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10042 area BSEG. Also moves, if possible, the DATA area down into the internal
10043 ram so more space is available.
10045 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10048 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10049 not bytes. Function summary() which creates a memory usage summary
10050 file with extension .mem. Reports of overlaping stack and small stack
10051 size. If the space for the stack is less than 16 bytes aslink trows a
10054 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10055 the 8051. Option 'y' for memory summary output file.
10057 Changes to sdcc (All the changes are marked with 'JCF'):
10059 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10061 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10062 overlaying area for it (uses RegBankUsed[4]).
10064 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10065 bank zero as used by default. By default aslink locates the stack
10066 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10067 the creation of the .mem file. Delegates the allocation of data area
10068 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10069 the begining of the stack area to aslink.
10071 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10072 glue() in SDCCglue.c creates an area for it.
10074 2002-09-03 Borut Razem <borut.razem AT siol.net>
10075 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10076 sdcc/src/pic/glue.c:
10077 introduced atexit() handler for teporay files removal in case of
10078 errors, assertions, ...
10080 2002-08-29 Borut Razem <borut.razem AT siol.net>
10081 * sdcc/support/cpp2/auto-host_vc_in.h:
10082 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10083 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10084 Maybe there is a similar problem with BORLANDC? It should be checked!
10086 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10087 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10088 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10089 was not executed, and the compiler (cl) launched a warning:
10090 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10092 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10093 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10095 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10096 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10098 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10099 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10100 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10101 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10102 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10103 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10104 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10105 - added Release configuration in VS projects
10106 - review of compiler an linker options
10107 - VC .exe files are generated in bin_vc directory, not to interfere
10108 with binaries generated from other projects (cygwin, mingw, bcc ...)
10110 * sdcc/src/yacc.dsp: added
10112 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10113 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10114 and insert the version number definitions from .version
10116 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10118 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10119 added - genarate auto-host.h using auto-host_vc_in.h as template
10122 removed from CVS, generated automatically
10124 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10125 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10127 2002-08-11 Borut Razem <borut.razem AT siol.net>
10128 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10130 2002-08-10 Borut Razem <borut.razem AT siol.net>
10131 * src/SDCCmain.c (main):
10132 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10133 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10134 The consequence was that some temporary files were not removed.
10137 unification of code in functions tempfilename() and tempfile():
10138 function tempnam() is defined in Visual Studio 6.0 and .NET
10140 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10142 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10143 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10144 - removed compiler command line option /WX: Treats all warnings as errors
10145 - update a list of source files, included into the project
10147 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10148 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10149 changed project type to Generic Project so that can be correcly converted to VS.NET project
10151 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10153 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10155 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10157 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10158 added return 0 statements after assert() to make compiler happy
10160 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10161 added newline in the def file to keep MSC compiler satisfied
10163 * sdcc/src/z80/gen.c:
10164 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10165 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10166 - solved MSC error in function aopDump()
10168 * sdcc_vc.h: define PREFIX as "\\sdcc"
10170 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10171 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10174 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10175 - Rewrote the register banking algorithm.
10176 - Added pCode live-range analysis to registers (for now, only non-used and
10177 singly-used registers optimized away)
10179 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10181 * 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.

10208 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10210 2002-03-28 Johan Knol <johan AT balder>
10212 * src/SDCCval.c: fixed bug #532436
10214 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10216 Added "char *Processor" field to the port structure.
10219 Added -p option. Allows port dependent processor to be specified.
10222 Initialized the new field char *Processor field to NULL in all ports
10225 Compiler generated registers for interrupt context saving
10226 were not getting allocated.
10228 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10231 Fixed left shift. Will promote the left side of a left shift
10232 if a) left shifting more than size of operand or b) when assigned
10233 to something size > size of left side
10235 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10237 tons of changes. Register allocation has been
10238 rewritten. Added customization for the various PICs. Flow
10239 analysis is restructured. ...
10241 * src/pic/device.h:
10244 * src/pic/device.c:
10245 Added. device.c is a PIC port hack to accomodate variations
10248 2002-03-13 Michael Hope <michaelh AT vroom>
10250 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10252 2002-03-04 johanknol <johanknol AT manik>
10254 * /src/SDCCval.c: fixed
10256 const unsigned char arr[][2] = { { 0, 1 } };

10343 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10345 * sdcc/src/SDCCloop.c:
10346 Previous fix was not good. basic blocks that have "break" or "return" are
10347 not really partof a loop , but live ranges used in these blocks should
10348 be live thru the entire loop, so set partOfLoop but don't add them to
10351 2002-02-21 <johan AT FRIJA>
10353 * src/SDCCcse.c: fixed bug #514308
10355 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10358 Fixed BUG #519583. If a conditional block ended in a return/break
10359 statement inside a loop, it was not being considered part of the loop.
10361 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10363 2002-02-10 Karl Bongers <karl AT turbobit.com>

10372 * device/examples/Makefile, examples/test3.c:
10373 Add Makefile in device/examples folder, compiles test3.c
10374 for use as a multiple module SDCDB test case.
10376 * sim/ucsim/cmd.src/cmdset.cc:
10377 Took out debug printfs in ucsim "next" command.
10379 * sim/ucsim/xa.src:
10380 Karl and Johan start ucsim XA support. Most dissassembly working,
10381 about 75% emulation done(plenty of work remaining).
10383 * sim/ucsim/z80.src:
10384 Add Z80 support to ucsim, add test-ucz80 regression test,
10385 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10386 Notice z80 compiler fails on examples/test3.c/crc code.
10388 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

10402 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10403 1) handle multiple send & receives from register bank1
10404 2) ralloc can now allocate DPTR1 to some liveRanges
10406 * src/SDCCsymt.c, src/SDCCsymt.h:
10407 changes to handle multiple sends & receives
10409 * src/SDCCptropt.h:
10410 added some pointer arithmetic optimization
10412 * src/SDCCptropt.c:

10419 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10420 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10421 set preprocessor defines (depending on options)
10423 * src/SDCCicode.c, src/SDCCicode.h:
10424 changes made to handle multiple sends & receives
