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

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

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

565 (commented out for reference), didn't account for some registers which
566 were left marked 'not free' after a pointer operation. The change
567 reduces register usage a lot in some cases

2925 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2927 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2929 * device/lib/printf_large.c: removed inline assembly for portability and
2930 readability. Use printf_fast if speed or size are more important.
2931 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2932 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2934 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2936 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2937 prevent compiler warning
2939 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2941 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2942 moved to level 0 and declared as static. Also they are explicit
2943 placed in access bank. This was necessery because some times they
2944 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2945 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2946 optimizations. Currently only compare to unsigned char is implemented,
2947 * src/pic16/gen.c: added fReturnIdx array,
2948 * (struct resolvedIfx) is moved to gen.h and made public,
2949 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2950 * (aopForSym): added an optimization to directly store in stack of
2951 the operand of a SEND iCode,
2952 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2953 but as registers instead (AOP_REG) using the fReturnIdx array,
2954 * (pic16_freeAsmop): remove the freed register from the
2955 _G.sregsAlloc field,
2956 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2957 a compare of 'WREG',
2958 * (pic16_popGetTempRegCond): changed function prototype, now
2959 function takes also a bitVector argument v which holds the current
2960 set of registers that are allocated for stack access by aopForSym,
2961 registers allocated in aopForSym for accessing stack symbols are not
2962 any more part of the functions usedRegs field,
2963 * (genCall): some times aopOp is called for a stack variable to be
2964 send, aopForSym might perform the push, if this is true make sure
2965 that genCall doesn't push the variable twice by testing _G.resDirect,
2966 * (genFunction): changed testing for unspecified interrupt number
2967 from 256 to INTNO_UNSPEC,
2968 * modified selection scheme of frame pointer generation. Previously
2969 if function did use local registers a frame pointer was generated,
2970 now a frame pointer is generated only if function has arguments
2971 (that need PLUSW2 register access), or has stack arguments, or the
2972 compiler is not instructed to omit the frame pointer,
2973 * (genEndFunction): before restoring local registers that were saved
2974 in the function preamble, also restore the registers that *might*
2975 have been allocated for stack access,
2976 * (genRet): removed some old comments,
2977 * (genCmp, the active (RN's) version): added a call to the
2978 pic16_genCmp_special function to perform the compare with a more
2979 robust and optimized way,
2980 * (genInline): a feature has been added in inline code generation,
2981 which allows a wildcard variable substitution when writing inline
2982 assembly. Code is incomplete and experimental therefore undocumented,
2983 * (genCast): changed order of aopOp for result and right to allow
2984 aopForSym to directly load the result if possible,
2985 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2986 perform an optimized compare on some selected special occasions,
2987 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2988 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2989 generate an IVT any more,
2990 * src/pic16/main.c (pic16_optionsTable): added command line option
2992 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2993 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2995 * src/pic16/NOTES: Raphael Neider added in list of active developers
2996 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2997 jumptable_end to prevent bug #,
2998 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2999 inCond and outCond fields,
3000 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3001 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3002 turn off register spilling,
3003 * (packRegsForOneUse): synced with other ports' versions although it
3004 is not used currently,
3005 * (pic16_packRegisters): added an optimization while reading
3006 structure bitfields, some registers may be saved (malloc code is
3007 decreased by 80 bytes)
3009 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3011 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3012 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3013 this can be optimized more?
3015 2005-03-10 Raphael Neider <rneider AT web.de>
3017 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3018 genNearPointerGet): (hopefully) fixed access to bitfields via
3019 pointers (p->bitN = x; and x = p->bitN; failed)
3021 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3023 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3653 Adding support for replacing ljmps with sjmps in jumptables
3654 generated for switch statements. For now you need to set the
3655 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3656 Now 4 algorithms for mcs51 jumptable generation are used:
3657 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3658 addresses loaded pc-relative for up to 112 cases and stack-pushing
3659 target addresses loaded with offset from dptr for up to 256 cases.

3689 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3691 * added libc directory. The current version of LibC contains string
3692 functions, ctype functions and macros and some functions of the
3693 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3694 be extensively tested in the future. Standard disclaimer here.
3695 Library is not automatically build yet. But one can build it by
3696 invoking 'make' inside the libc directory.

3707 * (pic16_storeForReturn): optimized return of 0,
3708 * (genCmp): experimental code for new genCmp which uses PIC18's
3709 special compare&skip instructions. Initial tests fail some times
3710 with variables grater than 1 byte in size, so new code is disabled,
3711 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3713 * (genCast): began a fix to optimize the casting of a bit to another
3714 bit, now assigning a bitfield to another bitfield will fail, sorry,

3723 and 1 for banking instruction,
3724 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3725 caused stop processing pCodes after a inline assembly block,
3726 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3727 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3728 registers when it shouldn't,
3729 * src/pic16/ralloc.c (allocReg): add preliminary support for
3730 supporting a limited set of temporary registers,
3732 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3738 (genFunction): optimize RECEIVE iCodes in reentrant functions
3740 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6740 loaded with the linker search paths (-L arguments) and the libraries
6741 to be linked with the current source (-l arguments). Changes
6742 currently will affect only the pic16 port.
6743 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6744 include path the port specific paths and port specific libraries,
6745 * gplink command now contains the $3 argument,
6746 * src/pic16/device.h,
6747 * src/pic16/device.c,: structure PIC_device is made public and
6748 renamed to PIC16_device, the same for variable Pics which is renamed

6763 Documenting changes from previous commits.
6764 * configure.in (version 1.56),
6765 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6766 when generating output files to configure the pic16 library,
6767 but now I've commented it out, since gputils aren't installed in the
6768 SF compile farm, so library won't compile
6770 * device/lib/Makefile.in (version 1.56): initially I've added in
6771 target 'all' the prerequestive 'model-pic16' so it compiled the
6772 pic16 library, but now I've commented it out for the same reasons
6774 * added targets 'model-pic16' and 'objects-pic16' to compile the
6776 * added target 'port-specific-objects-pic16' to handle the
6777 generated libraries and copy them into the build/ directory
6778 * added target 'clean-intermediate-pic16' to clean intermediate
6779 files into pic16 directory
6780 * in target 'installdirs' added line to create directory pic16 in

6784 added lines to copy all header files to installation path,
6785 * in target 'installdirs' added line create directory for pic16
6786 headers in the installation path

7034 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7036 A python script to validate compiler diagnostic messages. It can be
7037 used to verify that sdcc complains about bad c source code and
7038 gives a good location of the error.
7039 * support/valdiag/Makefile,
7040 * support/valdiag/valdiag.py,
7041 * support/valdiag/tests/*
7043 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7045 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7046 * src/SDCCsymt.c (newEnumType),
7048 * support/Util/SDCCerr.c,
7049 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7051 * support/regression/tests/enum.c: added test for enum values that
7052 require at least 2 bytes of storage.
7054 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7056 * src/common.h: added ifndef/define/endif macros
7057 around the header file.
7058 Bug reported from Jesus Calvino-Fraga
7060 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7062 * sdcc.spec: updated
7063 * device/include/Makefile.in: don't install CVS directories
7064 * device/lib/Makefile.in: added removal of CVS directories after install
7065 * doc/Makefile: fixed install, added local_icons
7066 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7067 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7068 * src/ds390/gen.c (genRightShift): fixed bug #870788
7069 * src/SDCCast.c (decorateType): fixed bug #870781
7071 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7073 PIC16 port related changes:
7074 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7075 added variable stackPos,
7077 * gen.c: genCall, assignResultValue: added support for
7078 pushing/retrieving function parameters to/from stack,
7079 genFunction,genEndFunction: setup stack frame for the
7081 genAddrOf: will be changed according to bug 863624
7083 * added files genutils.c and genutils.h which contain gen*
7084 debugged and optimised functions extracted from gen.c
7086 * glue.c: added variable 'externs' which holds extern symbols,
7087 pic16emitRegularMap: is modified to properly handle relocatable
7088 symbols under the new scheme,
7089 pic16createInterruptVect: is modified
7090 pic16printPublics: is modified to emit 'global' assembler directives,
7091 added pic16_printExterns to print extern symbols,
7092 pic16glue: initializes stack/frame pointer in the beginning of
7093 the assembly output. Temporary hack, will be corrected later,
7094 because gplink yet does not support stack and SDCC does not
7095 yet support a type of crt0.o object to create the final binary.
7097 * Removed many lines that contain 8051 legacy code.
7098 * The code is finally placed under a 'code' directive.
7099 * Added port specific options.
7101 * _process_pragma: simplified since now we do not need *special*
7102 include file to define SFR registers. But a separate header
7103 will be needed. This will be developed later.
7104 * _pic16_parseOptions: added, parses port specific options:
7105 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7106 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7107 --preplace-udata-with=
7109 * _pic16_setDefaultOptions: modified to initialize section names,
7110 but hack is temporarly out of order since it needs improvement.
7111 * _pic16_genAssemblerPreamble: configuration words are emitted by
7112 their address instead of their name. This part is incomplete and
7113 supports only the 18Fxx2 devices. Other devices will emit an error
7114 during assembly since they do not contain the same set of config
7116 * _pic16_genIVT: is modified,
7118 * pcode.c: added definitions for some hardware registers that are needed
7120 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7121 All PCI entries are updated. Now LFSR is supported.
7122 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7123 * added pic16_newpCodeOpLit2 to support instructions with
7124 two literal arguments
7125 * pic16_pCode2str: corrected code that emits assembler instructions
7126 with two literal operands and those that have an access bit modifier
7127 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7128 this fixes a bug which caused some labels to be lost, when an
7129 assembler directive was added, i.e. banksel,
7130 * pic16_FixRegisterBanking: improved logic that causes the insertion
7132 * InlineFunction: functions that are called once, are not any more
7133 inlined. This can be a port option in the future,
7135 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7137 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7138 hold the corresponding uninitialized symbols,
7139 * pic16_allocProcessorRegister: registers have explicit marked the
7141 * pic16_allocInternalRegister: registers are explicit marked as
7143 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7144 processing list, so bit registers were lost,
7147 * ralloc.h: added field 'accessBank' and original symbol operand
7148 in register definition,
7149 * removed the field isMapped from register definition,
7151 ** Several functions have been removed from various sources:
7152 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7153 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7154 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7155 pic16_assignRelocatableRegisters
7157 ** others have been introduced:
7158 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7159 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7161 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7163 * support/scripts/inc2h.pl: changed definition of BIT_AT
7164 to emit 'sbit at' instead of 'bit at'. This was a request.
7166 PIC16 port related preliminary changes:
7167 * gen.c: prefixed function popRegFromString with
7168 pic16_ and all references to it corrected
7169 * pcode.c: all pic16_pc_* hardware registers prefixed
7170 with underscore (_),
7171 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7172 * ralloc.c: newReg(): when register is REG_SFR then
7173 set address to rIdx,
7174 pic16_allocProcessorRegister(): marks register wasUsed=0
7175 pic16_writeUsedRegs(): added a call to assign processor
7176 registers via pic16_assignFixedRegisters
7178 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7180 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7181 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7182 variables in unused register banks. Also the SSEG is placed
7183 wherever there is enough space for it, and IDATA can be anywhere
7184 in internal RAM. For now compile using -Wl-Y[stack_size].
7185 The mem file is different for this option as well, since it
7186 makes no sense of talking about DSEG lenght.
7188 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7190 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7191 in certain cases, e.g. when ROM assignment, patch provided
7192 from Albert den Haan.
7194 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7337 * src/mcs51/peephole.def,
7338 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7433 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7435 * src/SDCCast.c (decorateType): disabled a transformation I added in
7436 revision 1.188 (access to fields of a structure at an absolute address);
7437 it breaks with bitfields, extern declarations, and gcse analysis.
7438 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7439 could be assigned through a pointer, so don't complain.
7440 * src/SDCCast.c (astErrors),
7442 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8080 support for standard C idiom of memory mapped variables; for
8081 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8082 to xdata int at 0x1234 tempvar = 1.
8083 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8084 provided by Akiya ISHIDA

8100 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8102 Fixed bug #621531 (const & volatile confusion in the type chain).
8103 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8104 refer to the const or volatile state of the pointer itself.

8195 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8196 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8197 fetching of the pointer
8198 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8199 copied from genNearPointerSet()
8200 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8201 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8202 If they pop r0/r1 they must be called in the opposite order than aopOp().
8203 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8204 (resp. --stack-auto), prepared for --xstack

8215 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8217 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8218 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8219 type for bits was changed. It resulted in bit variables becoming
8220 global, which is not permitted in PIC 14 assembly output.
8222 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8224 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8237 A few small changes that speed up the peephole optimizer.
8241 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8243 Try to make the peephole optimizer smarter by maintaining
8244 an association between the assembly source code and the
8245 iCodes that originated them. Put this information to use
8246 with a new peephole rule condition "notVolatile" so that
8247 the rules can be aggressive yet still safe.
8252 * src/mcs51/peeph.def
8254 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8258 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8259 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8260 if the left or right operand symbols have the accuse flag set.
8262 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8264 Changed the type of the result of the ! (NOT) operator to char;
8265 previously it returned the same type as the source. This allows
8266 us to eliminate all the genFloatNot functions (all of its target
8267 implementations were very buggy) since !float can use the same

8279 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8280 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8281 during interrupts. Ensure WSAVE is located at a shared bank address.
8282 2. Fixed page selection in some places
8283 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8284 the registers name strings.
8285 4. Fixed "signed / unsigned compare" compiler warnings.
8286 5. The PIC port manages its own allocation of the general purpose
8287 registers, but makes no attempt to reuse them. As a result when
8288 compiling it soon runs out of general purpose registers. Some
8289 additional code was added to the files pcode.c and device.c to walk
8290 through the function call tree and rename the registers so that they
8300 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8301 genPlus() & genMinus() when the result is the same as left or right

8307 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8309 Made bitfield a distinct type from bit so that bitfields
8310 convert as per ANSI C and bits retain their traditional
8311 boolean style behaviour. Implemented bitfield support in
8319 * src/ds390/gen.c: bit v bitfield split
8320 * src/z80/gen.c: New support for bitfields
8321 * support/regression/tests/bitfields.c: reenabled z80,
8324 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8326 Rules 246.x, 247.x relate to bitfields, the others speed up
8327 access to xdata mapped I/O devices.
8329 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8331 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8333 Cleaned up genPackBits and genUnpackBits and added two helper
8334 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8335 for literal assignments in genPackBits (thanks to Frieder for
8341 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8343 Fixed bug #748310 (pointer to function type mishandled when the
8344 function name is omitted). Also fixed a SIGSEGV when a function
8345 attribute (reentrant, etc) is used on a non-function or on a
8346 function but misplaced before the parameter list.
8348 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8350 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8351 * support/Util/SDCCerr.h,
8352 * support/Util/SDCCerr.c: Added func attr misuse error msg

8373 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8375 Made the constant following the "interrupt" keyword optional. If
8376 omitted, the function will not automatically be given an entry
8377 in the interrupt vector table (similar to #pragma NOIV, but
8378 less syntacticly kludgy). The interrupt number is also now
8379 range checked. Also fixed a bug in the high order bit example

8393 * src/SDCCicode.c (operandOperation): rewritten some ops
8394 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8395 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8397 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8398 be re-activated by defining REDUCE_LITERALS)
8399 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8400 unsigned, but are signed by default
8401 * src/SDCCval.c (constVal): rearranged
8402 * src/SDCCval.c (valMod): preliminary fix
8403 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8909 added if/endif conditional macros to remove options help
8910 messages from optionsTable when a port is not configured, added
8911 support for the PIc16 port in the ports table, when executing
8912 the compiler with no port specified on command line, a default
8913 port is selected with the new macro DEFAULT_PORT which is
8914 defined in port.h, in setDefaultOptions() linkOptions is removed
8915 from initialization assignment, since now it is a set,
8916 parseCmdLine uses setParseWithComma for linkOptions, in
8917 linkEdit() linkOptions are accessed with new function indexSet()
8918 which returns the i'th item of a set variable. See SDCCset.c, in
8919 linkEdit() when calling buildCmdLine(), added linkOptions as
8920 last argument. Now users can pass arguments to gplink via the
8921 -Wl option, main() uses pic16glue() to glue up pic16 programs

8935 gpasm complaining and test the linkage with gplink, _linkCmd and
8936 _asmCmd changed to be more gplink and gpasm friendly
8937 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8938 produced an error when parsed, peep rule 12 is added to utilize
8939 movff, but it is commented out since the pCode does not support
8940 yet a command with 2 address arguments
8942 2003-05-18 <johan AT balder>
8944 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8971 2003-05-11 Borut Razem <borut.razem AT siol.net>
8973 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9966 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9967 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9968 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9969 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

9977 2003-01-06 <johan AT balder>
9979 * src/SDCCicode.c: fixed array add
9981 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9982 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9983 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9985 2003-01-04 <johan AT balder>
9987 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9989 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9990 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9992 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9993 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9994 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9996 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9997 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9999 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10000 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10002 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10003 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10005 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10007 * in \sdcc\as\mcs51\ changed these files in order to create an
10008 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10009 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10010 following files to include the previous two files: aslink.dsp,
10011 Makefile.aslink, Makefile.bcc, and Makefile.in.
10013 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10014 .adb instead of .cdb
10016 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10018 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10019 value from option --iram-size.
10021 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10023 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10026 2002-09-18 <wiml AT hhhh.org>
10028 * SDCClrange.h: exposed setFromRange() and setToRange()
10029 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10030 packRegsForAccUse() (bug 542397)
10031 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10032 multiple times and emitting the fetch operations more than once
10033 added aopGetUsesAcc() function to allow binary operators to
10034 fetch their operands in the correct order; made genMinus() emit
10035 compact code for X = LITERAL - Y
10037 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10038 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10039 sprintf() in line 1267.
10041 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10042 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10045 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10046 Changes to aslink (All the changes are marked with 'JCF'):
10048 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10051 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10052 area BSEG. Also moves, if possible, the DATA area down into the internal
10053 ram so more space is available.
10055 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10058 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10059 not bytes. Function summary() which creates a memory usage summary
10060 file with extension .mem. Reports of overlaping stack and small stack
10061 size. If the space for the stack is less than 16 bytes aslink trows a
10064 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10065 the 8051. Option 'y' for memory summary output file.
10067 Changes to sdcc (All the changes are marked with 'JCF'):
10069 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10071 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10072 overlaying area for it (uses RegBankUsed[4]).
10074 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10075 bank zero as used by default. By default aslink locates the stack
10076 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10077 the creation of the .mem file. Delegates the allocation of data area
10078 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10079 the begining of the stack area to aslink.
10081 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10082 glue() in SDCCglue.c creates an area for it.
10084 2002-09-03 Borut Razem <borut.razem AT siol.net>
10085 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10086 sdcc/src/pic/glue.c:
10087 introduced atexit() handler for teporay files removal in case of
10088 errors, assertions, ...
10090 2002-08-29 Borut Razem <borut.razem AT siol.net>
10091 * sdcc/support/cpp2/auto-host_vc_in.h:
10092 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10093 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10094 Maybe there is a similar problem with BORLANDC? It should be checked!
10096 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10097 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10098 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10099 was not executed, and the compiler (cl) launched a warning:
10100 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10102 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10103 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10105 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10106 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10108 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10109 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10110 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10111 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10112 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10113 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10114 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10115 - added Release configuration in VS projects
10116 - review of compiler an linker options
10117 - VC .exe files are generated in bin_vc directory, not to interfere
10118 with binaries generated from other projects (cygwin, mingw, bcc ...)
10120 * sdcc/src/yacc.dsp: added
10122 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10123 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10124 and insert the version number definitions from .version
10126 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10128 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10129 added - genarate auto-host.h using auto-host_vc_in.h as template
10132 removed from CVS, generated automatically
10134 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10135 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10137 2002-08-11 Borut Razem <borut.razem AT siol.net>
10138 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10140 2002-08-10 Borut Razem <borut.razem AT siol.net>
10141 * src/SDCCmain.c (main):
10142 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10143 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10144 The consequence was that some temporary files were not removed.
10147 unification of code in functions tempfilename() and tempfile():
10148 function tempnam() is defined in Visual Studio 6.0 and .NET
10150 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10152 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10153 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10154 - removed compiler command line option /WX: Treats all warnings as errors
10155 - update a list of source files, included into the project
10157 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10158 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10159 changed project type to Generic Project so that can be correcly converted to VS.NET project
10161 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10163 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10165 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10167 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10168 added return 0 statements after assert() to make compiler happy
10170 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10171 added newline in the def file to keep MSC compiler satisfied
10173 * sdcc/src/z80/gen.c:
10174 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10175 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10176 - solved MSC error in function aopDump()
10178 * sdcc_vc.h: define PREFIX as "\\sdcc"
10180 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10181 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10184 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10185 - Rewrote the register banking algorithm.
10186 - Added pCode live-range analysis to registers (for now, only non-used and
10187 singly-used registers optimized away)
10189 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10191 * 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.

10214 * src/z80/main.c: Added force callee saves for jaune.
10216 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10218 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10220 2002-03-28 Johan Knol <johan AT balder>
10222 * src/SDCCval.c: fixed bug #532436
10224 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10226 Added "char *Processor" field to the port structure.
10229 Added -p option. Allows port dependent processor to be specified.
10232 Initialized the new field char *Processor field to NULL in all ports
10235 Compiler generated registers for interrupt context saving
10236 were not getting allocated.
10238 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10241 Fixed left shift. Will promote the left side of a left shift
10242 if a) left shifting more than size of operand or b) when assigned
10243 to something size > size of left side
10245 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10247 tons of changes. Register allocation has been
10248 rewritten. Added customization for the various PICs. Flow
10249 analysis is restructured. ...
10251 * src/pic/device.h:
10254 * src/pic/device.c:
10255 Added. device.c is a PIC port hack to accomodate variations
10258 2002-03-13 Michael Hope <michaelh AT vroom>
10260 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10262 2002-03-04 johanknol <johanknol AT manik>
10264 * /src/SDCCval.c: fixed
10266 const unsigned char arr[][2] = { { 0, 1 } };
10267 t18.c:1: error: Initializer element is not constant

10353 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10355 * sdcc/src/SDCCloop.c:
10356 Previous fix was not good. basic blocks that have "break" or "return" are
10357 not really partof a loop , but live ranges used in these blocks should
10358 be live thru the entire loop, so set partOfLoop but don't add them to
10361 2002-02-21 <johan AT FRIJA>
10363 * src/SDCCcse.c: fixed bug #514308
10365 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10368 Fixed BUG #519583. If a conditional block ended in a return/break
10369 statement inside a loop, it was not being considered part of the loop.
10371 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10373 2002-02-10 Karl Bongers <karl AT turbobit.com>

10377 with lots of comments and notes.
10379 * device/examples/test2.c:
10380 Fix bug, "red" variable not being initialized(compiler complained).
10382 * device/examples/Makefile, examples/test3.c:
10383 Add Makefile in device/examples folder, compiles test3.c
10384 for use as a multiple module SDCDB test case.
10386 * sim/ucsim/cmd.src/cmdset.cc:
10387 Took out debug printfs in ucsim "next" command.
10389 * sim/ucsim/xa.src:
10390 Karl and Johan start ucsim XA support. Most dissassembly working,
10391 about 75% emulation done(plenty of work remaining).
10393 * sim/ucsim/z80.src:
10394 Add Z80 support to ucsim, add test-ucz80 regression test,
10395 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10396 Notice z80 compiler fails on examples/test3.c/crc code.
10398 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10400 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10410 3) added __builtin_swapw swap bytes of a short
10412 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10413 1) handle multiple send & receives from register bank1
10414 2) ralloc can now allocate DPTR1 to some liveRanges
10416 * src/SDCCsymt.c, src/SDCCsymt.h:
10417 changes to handle multiple sends & receives
10419 * src/SDCCptropt.h:
10420 added some pointer arithmetic optimization
10422 * src/SDCCptropt.c:
10423 added some pointer arithmetic optimizations but not stable yet so not
10424 called from anywhere (will get this working shortly)
10426 * src/SDCCopt.c: fixed for multiple sends & receives
10429 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10430 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10431 set preprocessor defines (depending on options)
