147 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
149 Enabled VPATH feature: changed nearly all Makefiles (149 files).
150 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
152 One basic decision: e.g. src/clean.mk includes further files. In order
153 to make this work there are two solutions:
154 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
155 run configure on them. This way they can use
156 'include $(srcdir)/port-clean.mk'
157 - always include clean.mk by the Makefile at the same level. To avoid
158 that `make clean` tries to include and build Makefile.dep the
159 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
160 implemented, because now even `make uninstall` doesn't create
161 Makefile.in. clean.mk could be eliminated by pasting it in
164 * debugger/mcs51/Makefile.in: build own objects from library sources
165 (SLIB, SDCC) in current directory
167 * configure, configure.in: renamed --disable-device-lib-build in
168 --disable-device-lib; added --enable-doc, the required tools are
169 searched by configure; added result message; the toolchain for the
170 belonging ports are now only built, if the port is enabled.
172 * support/regression/*: all output is written in directory gen, because
173 the fwk and ports directories don't livet in the build tree using vpath
175 * doc/sdccman.lyx: renamed --disable-device-lib-build to
176 --disable-device-lib, added --enable-doc, added section VPATH
178 * sim/ucsim/configure.in,
179 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
180 z80 are enabled by default
182 2006-04-24 Raphael Neider <rneider AT web.de>
184 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
185 to config word, "pic14_"-prefixed some extern functions
186 (pic14_emitConfigWord): emit __config directive(s) if assignment to
187 config word has been found
188 * src/pic/device.h: added prototypes
189 * src/pic/pcode.c: added "pic14_"-prefix where needed
190 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
192 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
194 (pic14emitRegularMap): ignore config words,
195 (pic14createInterruptVect): moved generating __config directives away

206 fixes #1469504 and #1474602,
207 (pCodeRegOptimizeRegUsage): fixed typo in comment

472 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
475 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
477 * src/.version: increased version number to 2.5.5
478 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
479 linking is done manually in pic16 port's _linkEdit,
480 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
481 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
482 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
483 allocate asmop as AOP_ACC,
484 (aopForRemat): added parameter 'bool result' in function declaration,
485 (pic16_aopGet): return AOP_ACC when accessing WREG,
486 (pic16_popGetTempReg): minor modification,

495 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
497 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
498 call to allocReg, not by manually allocating a new one,
499 (pic16_assignRegisters): now before going through the register
500 allocating functions mark all registers as free. This eliminates some
501 side effects resulting from peephole parser done earlier in the backbone
503 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

524 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
525 (aopForSym, aopOp): increment asmop.allocated if reused,
526 (freeAsmop): decrement asmop.allocated and check for zero instead of

561 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
562 which dumps before the function entry point a data byte which represents
563 the number of the local variables used by the specified function, added
564 'xinst' for initial support for Extended Instruction Support,
565 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
566 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
567 port->fun_prefix anymore (may change later),
568 (genFunction, genEndFunction): do not store/restore local registers for
569 _main (this should take care the --main-return command line option in
571 (genOr): removed some legacy pic-port instructions,
572 * src/pic16/genarith.c (genAddLit): re-enabled old code because
573 performing operations with SFR's causes data to be written more than
574 once to each SFR. Perhaps SFRs should be handled in special cases...
575 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
577 * src/pic16/main.c (_process_pragma): stack bound checking did not take
578 into account for stack starting position,

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

2943 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2945 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2947 * device/lib/printf_large.c: removed inline assembly for portability and
2948 readability. Use printf_fast if speed or size are more important.
2949 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2950 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2952 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2954 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2955 prevent compiler warning
2957 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2959 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2960 moved to level 0 and declared as static. Also they are explicit
2961 placed in access bank. This was necessery because some times they
2962 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2963 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2964 optimizations. Currently only compare to unsigned char is implemented,
2965 * src/pic16/gen.c: added fReturnIdx array,
2966 * (struct resolvedIfx) is moved to gen.h and made public,
2967 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2968 * (aopForSym): added an optimization to directly store in stack of
2969 the operand of a SEND iCode,
2970 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2971 but as registers instead (AOP_REG) using the fReturnIdx array,
2972 * (pic16_freeAsmop): remove the freed register from the
2973 _G.sregsAlloc field,
2974 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2975 a compare of 'WREG',
2976 * (pic16_popGetTempRegCond): changed function prototype, now
2977 function takes also a bitVector argument v which holds the current
2978 set of registers that are allocated for stack access by aopForSym,
2979 registers allocated in aopForSym for accessing stack symbols are not
2980 any more part of the functions usedRegs field,
2981 * (genCall): some times aopOp is called for a stack variable to be
2982 send, aopForSym might perform the push, if this is true make sure
2983 that genCall doesn't push the variable twice by testing _G.resDirect,
2984 * (genFunction): changed testing for unspecified interrupt number
2985 from 256 to INTNO_UNSPEC,
2986 * modified selection scheme of frame pointer generation. Previously
2987 if function did use local registers a frame pointer was generated,
2988 now a frame pointer is generated only if function has arguments
2989 (that need PLUSW2 register access), or has stack arguments, or the
2990 compiler is not instructed to omit the frame pointer,
2991 * (genEndFunction): before restoring local registers that were saved
2992 in the function preamble, also restore the registers that *might*
2993 have been allocated for stack access,
2994 * (genRet): removed some old comments,
2995 * (genCmp, the active (RN's) version): added a call to the
2996 pic16_genCmp_special function to perform the compare with a more
2997 robust and optimized way,
2998 * (genInline): a feature has been added in inline code generation,
2999 which allows a wildcard variable substitution when writing inline
3000 assembly. Code is incomplete and experimental therefore undocumented,
3001 * (genCast): changed order of aopOp for result and right to allow
3002 aopForSym to directly load the result if possible,
3003 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3004 perform an optimized compare on some selected special occasions,
3005 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3006 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3007 generate an IVT any more,
3008 * src/pic16/main.c (pic16_optionsTable): added command line option
3010 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3011 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3013 * src/pic16/NOTES: Raphael Neider added in list of active developers
3014 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3015 jumptable_end to prevent bug #,
3016 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3017 inCond and outCond fields,
3018 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3019 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3020 turn off register spilling,
3021 * (packRegsForOneUse): synced with other ports' versions although it
3022 is not used currently,
3023 * (pic16_packRegisters): added an optimization while reading
3024 structure bitfields, some registers may be saved (malloc code is
3025 decreased by 80 bytes)

3671 Adding support for replacing ljmps with sjmps in jumptables
3672 generated for switch statements. For now you need to set the
3673 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3674 Now 4 algorithms for mcs51 jumptable generation are used:
3675 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3676 addresses loaded pc-relative for up to 112 cases and stack-pushing
3677 target addresses loaded with offset from dptr for up to 256 cases.

3707 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3709 * added libc directory. The current version of LibC contains string
3710 functions, ctype functions and macros and some functions of the
3711 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3712 be extensively tested in the future. Standard disclaimer here.
3713 Library is not automatically build yet. But one can build it by
3714 invoking 'make' inside the libc directory.

3725 * (pic16_storeForReturn): optimized return of 0,
3726 * (genCmp): experimental code for new genCmp which uses PIC18's
3727 special compare&skip instructions. Initial tests fail some times
3728 with variables grater than 1 byte in size, so new code is disabled,
3729 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3731 * (genCast): began a fix to optimize the casting of a bit to another
3732 bit, now assigning a bitfield to another bitfield will fail, sorry,

3741 and 1 for banking instruction,
3742 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3743 caused stop processing pCodes after a inline assembly block,
3744 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3746 registers when it shouldn't,
3747 * src/pic16/ralloc.c (allocReg): add preliminary support for
3748 supporting a limited set of temporary registers,
3750 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6758 loaded with the linker search paths (-L arguments) and the libraries
6759 to be linked with the current source (-l arguments). Changes
6760 currently will affect only the pic16 port.
6761 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6762 include path the port specific paths and port specific libraries,
6763 * gplink command now contains the $3 argument,
6764 * src/pic16/device.h,

6781 Documenting changes from previous commits.
6782 * configure.in (version 1.56),
6783 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6784 when generating output files to configure the pic16 library,
6785 but now I've commented it out, since gputils aren't installed in the
6786 SF compile farm, so library won't compile
6788 * device/lib/Makefile.in (version 1.56): initially I've added in
6789 target 'all' the prerequestive 'model-pic16' so it compiled the
6790 pic16 library, but now I've commented it out for the same reasons
6792 * added targets 'model-pic16' and 'objects-pic16' to compile the
6794 * added target 'port-specific-objects-pic16' to handle the
6795 generated libraries and copy them into the build/ directory
6796 * added target 'clean-intermediate-pic16' to clean intermediate
6797 files into pic16 directory
6798 * in target 'installdirs' added line to create directory pic16 in

6802 added lines to copy all header files to installation path,
6803 * in target 'installdirs' added line create directory for pic16
6804 headers in the installation path

7038 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7040 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
7042 * support/valdiag/tests/overflow.c: added
7043 * src/SDCCast.c (decorateType),
7044 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7045 LEFT_OP (left shift)
7047 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7049 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7050 (default behaviour).
7052 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7054 A python script to validate compiler diagnostic messages. It can be
7055 used to verify that sdcc complains about bad c source code and
7056 gives a good location of the error.
7057 * support/valdiag/Makefile,
7058 * support/valdiag/valdiag.py,
7059 * support/valdiag/tests/*
7061 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7063 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7064 * src/SDCCsymt.c (newEnumType),
7066 * support/Util/SDCCerr.c,
7067 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7069 * support/regression/tests/enum.c: added test for enum values that
7070 require at least 2 bytes of storage.
7072 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7074 * src/common.h: added ifndef/define/endif macros
7075 around the header file.
7076 Bug reported from Jesus Calvino-Fraga
7078 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7080 * sdcc.spec: updated
7081 * device/include/Makefile.in: don't install CVS directories
7082 * device/lib/Makefile.in: added removal of CVS directories after install
7083 * doc/Makefile: fixed install, added local_icons
7084 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7085 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7086 * src/ds390/gen.c (genRightShift): fixed bug #870788
7087 * src/SDCCast.c (decorateType): fixed bug #870781
7089 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7091 PIC16 port related changes:
7092 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7093 added variable stackPos,
7095 * gen.c: genCall, assignResultValue: added support for
7096 pushing/retrieving function parameters to/from stack,
7097 genFunction,genEndFunction: setup stack frame for the
7099 genAddrOf: will be changed according to bug 863624
7101 * added files genutils.c and genutils.h which contain gen*
7102 debugged and optimised functions extracted from gen.c
7104 * glue.c: added variable 'externs' which holds extern symbols,
7105 pic16emitRegularMap: is modified to properly handle relocatable
7106 symbols under the new scheme,
7107 pic16createInterruptVect: is modified
7108 pic16printPublics: is modified to emit 'global' assembler directives,
7109 added pic16_printExterns to print extern symbols,
7110 pic16glue: initializes stack/frame pointer in the beginning of
7111 the assembly output. Temporary hack, will be corrected later,
7112 because gplink yet does not support stack and SDCC does not
7113 yet support a type of crt0.o object to create the final binary.
7115 * Removed many lines that contain 8051 legacy code.
7116 * The code is finally placed under a 'code' directive.
7117 * Added port specific options.
7119 * _process_pragma: simplified since now we do not need *special*
7120 include file to define SFR registers. But a separate header
7121 will be needed. This will be developed later.
7122 * _pic16_parseOptions: added, parses port specific options:
7123 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7124 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7125 --preplace-udata-with=
7127 * _pic16_setDefaultOptions: modified to initialize section names,
7128 but hack is temporarly out of order since it needs improvement.
7129 * _pic16_genAssemblerPreamble: configuration words are emitted by
7130 their address instead of their name. This part is incomplete and
7131 supports only the 18Fxx2 devices. Other devices will emit an error
7132 during assembly since they do not contain the same set of config
7134 * _pic16_genIVT: is modified,
7136 * pcode.c: added definitions for some hardware registers that are needed
7138 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7139 All PCI entries are updated. Now LFSR is supported.
7140 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7141 * added pic16_newpCodeOpLit2 to support instructions with
7142 two literal arguments
7143 * pic16_pCode2str: corrected code that emits assembler instructions
7144 with two literal operands and those that have an access bit modifier
7145 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7146 this fixes a bug which caused some labels to be lost, when an
7147 assembler directive was added, i.e. banksel,
7148 * pic16_FixRegisterBanking: improved logic that causes the insertion
7150 * InlineFunction: functions that are called once, are not any more
7151 inlined. This can be a port option in the future,
7153 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7155 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7156 hold the corresponding uninitialized symbols,
7157 * pic16_allocProcessorRegister: registers have explicit marked the
7159 * pic16_allocInternalRegister: registers are explicit marked as
7161 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7162 processing list, so bit registers were lost,
7165 * ralloc.h: added field 'accessBank' and original symbol operand
7166 in register definition,
7167 * removed the field isMapped from register definition,
7169 ** Several functions have been removed from various sources:
7170 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7171 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7172 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7173 pic16_assignRelocatableRegisters
7175 ** others have been introduced:
7176 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7177 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7179 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7181 * support/scripts/inc2h.pl: changed definition of BIT_AT
7182 to emit 'sbit at' instead of 'bit at'. This was a request.
7184 PIC16 port related preliminary changes:
7185 * gen.c: prefixed function popRegFromString with
7186 pic16_ and all references to it corrected
7187 * pcode.c: all pic16_pc_* hardware registers prefixed
7188 with underscore (_),
7189 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7190 * ralloc.c: newReg(): when register is REG_SFR then
7191 set address to rIdx,
7192 pic16_allocProcessorRegister(): marks register wasUsed=0
7193 pic16_writeUsedRegs(): added a call to assign processor
7194 registers via pic16_assignFixedRegisters
7196 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7198 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7199 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7200 variables in unused register banks. Also the SSEG is placed
7201 wherever there is enough space for it, and IDATA can be anywhere
7202 in internal RAM. For now compile using -Wl-Y[stack_size].
7203 The mem file is different for this option as well, since it
7204 makes no sense of talking about DSEG lenght.
7206 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7208 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7209 in certain cases, e.g. when ROM assignment, patch provided
7210 from Albert den Haan.
7212 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7355 * src/mcs51/peephole.def,
7356 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7368 multiply defined with mismatching "at" address.
7370 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7372 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
7373 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

7451 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7453 * src/SDCCast.c (decorateType): disabled a transformation I added in
7454 revision 1.188 (access to fields of a structure at an absolute address);
7455 it breaks with bitfields, extern declarations, and gcse analysis.
7456 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7457 could be assigned through a pointer, so don't complain.
7458 * src/SDCCast.c (astErrors),
7460 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8097 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8098 support for standard C idiom of memory mapped variables; for
8099 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8100 to xdata int at 0x1234 tempvar = 1.
8101 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8102 provided by Akiya ISHIDA

8118 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8120 Fixed bug #621531 (const & volatile confusion in the type chain).
8121 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8122 refer to the const or volatile state of the pointer itself.

8213 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8214 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8215 fetching of the pointer
8216 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8217 copied from genNearPointerSet()
8218 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8219 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8220 If they pop r0/r1 they must be called in the opposite order than aopOp().
8221 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8222 (resp. --stack-auto), prepared for --xstack

8233 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8235 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8236 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8237 type for bits was changed. It resulted in bit variables becoming
8238 global, which is not permitted in PIC 14 assembly output.
8240 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8242 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8255 A few small changes that speed up the peephole optimizer.
8259 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8261 Try to make the peephole optimizer smarter by maintaining
8262 an association between the assembly source code and the
8263 iCodes that originated them. Put this information to use
8264 with a new peephole rule condition "notVolatile" so that
8265 the rules can be aggressive yet still safe.
8270 * src/mcs51/peeph.def
8272 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8276 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8277 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8278 if the left or right operand symbols have the accuse flag set.
8280 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8282 Changed the type of the result of the ! (NOT) operator to char;
8283 previously it returned the same type as the source. This allows
8284 us to eliminate all the genFloatNot functions (all of its target
8285 implementations were very buggy) since !float can use the same
8288 * src/SDCCicode.c (ast2iCode): ! returns char

8297 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8298 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8299 during interrupts. Ensure WSAVE is located at a shared bank address.
8300 2. Fixed page selection in some places
8301 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8302 the registers name strings.
8303 4. Fixed "signed / unsigned compare" compiler warnings.
8304 5. The PIC port manages its own allocation of the general purpose
8305 registers, but makes no attempt to reuse them. As a result when
8306 compiling it soon runs out of general purpose registers. Some
8307 additional code was added to the files pcode.c and device.c to walk
8308 through the function call tree and rename the registers so that they
8318 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8319 genPlus() & genMinus() when the result is the same as left or right
8321 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8325 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8327 Made bitfield a distinct type from bit so that bitfields
8328 convert as per ANSI C and bits retain their traditional
8329 boolean style behaviour. Implemented bitfield support in
8337 * src/ds390/gen.c: bit v bitfield split
8338 * src/z80/gen.c: New support for bitfields
8339 * support/regression/tests/bitfields.c: reenabled z80,
8342 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8344 Rules 246.x, 247.x relate to bitfields, the others speed up
8345 access to xdata mapped I/O devices.
8347 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8349 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8351 Cleaned up genPackBits and genUnpackBits and added two helper
8352 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8353 for literal assignments in genPackBits (thanks to Frieder for
8359 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8361 Fixed bug #748310 (pointer to function type mishandled when the
8362 function name is omitted). Also fixed a SIGSEGV when a function
8363 attribute (reentrant, etc) is used on a non-function or on a
8364 function but misplaced before the parameter list.
8366 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8368 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8369 * support/Util/SDCCerr.h,
8370 * support/Util/SDCCerr.c: Added func attr misuse error msg
8372 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8374 Fixed bug #787649 by anonymous
8375 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8391 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8393 Made the constant following the "interrupt" keyword optional. If
8394 omitted, the function will not automatically be given an entry
8395 in the interrupt vector table (similar to #pragma NOIV, but
8396 less syntacticly kludgy). The interrupt number is also now
8397 range checked. Also fixed a bug in the high order bit example

8411 * src/SDCCicode.c (operandOperation): rewritten some ops
8412 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8413 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8415 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8416 be re-activated by defining REDUCE_LITERALS)
8417 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8418 unsigned, but are signed by default
8419 * src/SDCCval.c (constVal): rearranged
8420 * src/SDCCval.c (valMod): preliminary fix
8421 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8463 constants are unsigned; added recognition of "u" flag for unsigned
8464 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8465 * src/SDCCval.c (valDiv, valMod): fixed signdness
8466 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8467 signedness of modulo, left and right shift

8926 * src/SDCCmain.c: linkOptions is changed to set *,
8927 added if/endif conditional macros to remove options help
8928 messages from optionsTable when a port is not configured, added
8929 support for the PIc16 port in the ports table, when executing
8930 the compiler with no port specified on command line, a default
8931 port is selected with the new macro DEFAULT_PORT which is
8932 defined in port.h, in setDefaultOptions() linkOptions is removed
8933 from initialization assignment, since now it is a set,
8934 parseCmdLine uses setParseWithComma for linkOptions, in
8935 linkEdit() linkOptions are accessed with new function indexSet()
8936 which returns the i'th item of a set variable. See SDCCset.c, in
8937 linkEdit() when calling buildCmdLine(), added linkOptions as
8938 last argument. Now users can pass arguments to gplink via the
8939 -Wl option, main() uses pic16glue() to glue up pic16 programs

8953 gpasm complaining and test the linkage with gplink, _linkCmd and
8954 _asmCmd changed to be more gplink and gpasm friendly
8955 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8956 produced an error when parsed, peep rule 12 is added to utilize
8957 movff, but it is commented out since the pCode does not support
8958 yet a command with 2 address arguments
8960 2003-05-18 <johan AT balder>
8962 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8989 2003-05-11 Borut Razem <borut.razem AT siol.net>
8991 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9982 * src/SDCCast.c (decorateType): fixed bug #600035
9984 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9985 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9986 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9987 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
9988 * src/pic/pcode.c: outcommented unused variable to remove warnings

9995 2003-01-06 <johan AT balder>
9997 * src/SDCCicode.c: fixed array add
9999 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10000 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10001 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10003 2003-01-04 <johan AT balder>
10005 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10007 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10008 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10010 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10011 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10012 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10014 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10015 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10017 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10018 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10020 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10021 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10023 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10025 * in \sdcc\as\mcs51\ changed these files in order to create an
10026 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10027 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10028 following files to include the previous two files: aslink.dsp,
10029 Makefile.aslink, Makefile.bcc, and Makefile.in.
10031 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10032 .adb instead of .cdb
10034 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10036 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10037 value from option --iram-size.
10039 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10041 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10044 2002-09-18 <wiml AT hhhh.org>
10046 * SDCClrange.h: exposed setFromRange() and setToRange()
10047 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10048 packRegsForAccUse() (bug 542397)
10049 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10050 multiple times and emitting the fetch operations more than once
10051 added aopGetUsesAcc() function to allow binary operators to
10052 fetch their operands in the correct order; made genMinus() emit
10053 compact code for X = LITERAL - Y
10055 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10056 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10057 sprintf() in line 1267.
10059 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10060 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10063 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10064 Changes to aslink (All the changes are marked with 'JCF'):
10066 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10069 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10070 area BSEG. Also moves, if possible, the DATA area down into the internal
10071 ram so more space is available.
10073 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10076 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10077 not bytes. Function summary() which creates a memory usage summary
10078 file with extension .mem. Reports of overlaping stack and small stack
10079 size. If the space for the stack is less than 16 bytes aslink trows a
10082 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10083 the 8051. Option 'y' for memory summary output file.
10085 Changes to sdcc (All the changes are marked with 'JCF'):
10087 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10089 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10090 overlaying area for it (uses RegBankUsed[4]).
10092 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10093 bank zero as used by default. By default aslink locates the stack
10094 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10095 the creation of the .mem file. Delegates the allocation of data area
10096 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10097 the begining of the stack area to aslink.
10099 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10100 glue() in SDCCglue.c creates an area for it.
10102 2002-09-03 Borut Razem <borut.razem AT siol.net>
10103 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10104 sdcc/src/pic/glue.c:
10105 introduced atexit() handler for teporay files removal in case of
10106 errors, assertions, ...
10108 2002-08-29 Borut Razem <borut.razem AT siol.net>
10109 * sdcc/support/cpp2/auto-host_vc_in.h:
10110 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10111 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10112 Maybe there is a similar problem with BORLANDC? It should be checked!
10114 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10115 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10116 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10117 was not executed, and the compiler (cl) launched a warning:
10118 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10120 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10121 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10123 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10124 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10126 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10127 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10128 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10129 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10130 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10131 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10132 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10133 - added Release configuration in VS projects
10134 - review of compiler an linker options
10135 - VC .exe files are generated in bin_vc directory, not to interfere
10136 with binaries generated from other projects (cygwin, mingw, bcc ...)
10138 * sdcc/src/yacc.dsp: added
10140 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10141 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10142 and insert the version number definitions from .version
10144 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10146 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10147 added - genarate auto-host.h using auto-host_vc_in.h as template
10150 removed from CVS, generated automatically
10152 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10153 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10155 2002-08-11 Borut Razem <borut.razem AT siol.net>
10156 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10158 2002-08-10 Borut Razem <borut.razem AT siol.net>
10159 * src/SDCCmain.c (main):
10160 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10161 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10162 The consequence was that some temporary files were not removed.
10165 unification of code in functions tempfilename() and tempfile():
10166 function tempnam() is defined in Visual Studio 6.0 and .NET
10168 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10170 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10171 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10172 - removed compiler command line option /WX: Treats all warnings as errors
10173 - update a list of source files, included into the project
10175 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10176 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10177 changed project type to Generic Project so that can be correcly converted to VS.NET project
10179 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10181 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10183 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10185 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10186 added return 0 statements after assert() to make compiler happy
10188 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10189 added newline in the def file to keep MSC compiler satisfied
10191 * sdcc/src/z80/gen.c:
10192 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10193 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10194 - solved MSC error in function aopDump()
10196 * sdcc_vc.h: define PREFIX as "\\sdcc"
10198 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10199 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10202 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10203 - Rewrote the register banking algorithm.
10204 - Added pCode live-range analysis to registers (for now, only non-used and
10205 singly-used registers optimized away)
10207 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10209 * 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.

10232 * src/z80/main.c: Added force callee saves for jaune.
10234 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10236 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10238 2002-03-28 Johan Knol <johan AT balder>
10240 * src/SDCCval.c: fixed bug #532436
10242 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10244 Added "char *Processor" field to the port structure.
10247 Added -p option. Allows port dependent processor to be specified.
10250 Initialized the new field char *Processor field to NULL in all ports
10253 Compiler generated registers for interrupt context saving
10254 were not getting allocated.
10256 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10259 Fixed left shift. Will promote the left side of a left shift
10260 if a) left shifting more than size of operand or b) when assigned
10261 to something size > size of left side
10263 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10265 tons of changes. Register allocation has been
10266 rewritten. Added customization for the various PICs. Flow
10267 analysis is restructured. ...
10269 * src/pic/device.h:
10272 * src/pic/device.c:
10273 Added. device.c is a PIC port hack to accomodate variations
10276 2002-03-13 Michael Hope <michaelh AT vroom>
10278 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10280 2002-03-04 johanknol <johanknol AT manik>
10282 * /src/SDCCval.c: fixed
10284 const unsigned char arr[][2] = { { 0, 1 } };
10285 t18.c:1: error: Initializer element is not constant

10371 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10373 * sdcc/src/SDCCloop.c:
10374 Previous fix was not good. basic blocks that have "break" or "return" are
10375 not really partof a loop , but live ranges used in these blocks should
10376 be live thru the entire loop, so set partOfLoop but don't add them to
10379 2002-02-21 <johan AT FRIJA>
10381 * src/SDCCcse.c: fixed bug #514308
10383 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10386 Fixed BUG #519583. If a conditional block ended in a return/break
10387 statement inside a loop, it was not being considered part of the loop.
10389 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10391 2002-02-10 Karl Bongers <karl AT turbobit.com>
10394 Fixed up SDCDB debugger somewhat. Updated debugger/README
10395 with lots of comments and notes.
10397 * device/examples/test2.c:
10398 Fix bug, "red" variable not being initialized(compiler complained).
10400 * device/examples/Makefile, examples/test3.c:
10401 Add Makefile in device/examples folder, compiles test3.c
10402 for use as a multiple module SDCDB test case.
10404 * sim/ucsim/cmd.src/cmdset.cc:
10405 Took out debug printfs in ucsim "next" command.
10407 * sim/ucsim/xa.src:
10408 Karl and Johan start ucsim XA support. Most dissassembly working,
10409 about 75% emulation done(plenty of work remaining).
10411 * sim/ucsim/z80.src:
10412 Add Z80 support to ucsim, add test-ucz80 regression test,
10413 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10414 Notice z80 compiler fails on examples/test3.c/crc code.
10416 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10418 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10425 1) added __builtin_inp & __builtin_outp used to read in data of given length
10426 from a memory mapped port
10427 2) added __builtin_memcmp
10428 3) added __builtin_swapw swap bytes of a short
10430 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10431 1) handle multiple send & receives from register bank1
10432 2) ralloc can now allocate DPTR1 to some liveRanges
10434 * src/SDCCsymt.c, src/SDCCsymt.h:
10435 changes to handle multiple sends & receives
10437 * src/SDCCptropt.h:
10438 added some pointer arithmetic optimization
10440 * src/SDCCptropt.c:
