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

472 2006-03-16 Raphael Neider <rneider AT web.de>
474 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
475 the left operand is shorter than the result (c* = lit-c* + int),
477 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
480 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
482 * src/.version: increased version number to 2.5.5
483 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
484 linking is done manually in pic16 port's _linkEdit,
485 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
486 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
487 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
488 allocate asmop as AOP_ACC,
489 (aopForRemat): added parameter 'bool result' in function declaration,
490 (pic16_aopGet): return AOP_ACC when accessing WREG,
491 (pic16_popGetTempReg): minor modification,
492 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
493 'pic16_allocWithIdx',
494 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
495 calling function in absolute addresses,
496 (genAssign): take into account AOP_ACC asmop,
497 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
498 * src/pic16/pcoderegs.c: some debug functions and lines added,
499 * src/pic16/ralloc.c (decodeRegType): added but commented out,
500 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
502 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
503 call to allocReg, not by manually allocating a new one,
504 (pic16_assignRegisters): now before going through the register
505 allocating functions mark all registers as free. This eliminates some
506 side effects resulting from peephole parser done earlier in the backbone
508 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

529 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
530 (aopForSym, aopOp): increment asmop.allocated if reused,
531 (freeAsmop): decrement asmop.allocated and check for zero instead of
533 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
534 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

566 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
567 which dumps before the function entry point a data byte which represents
568 the number of the local variables used by the specified function, added
569 'xinst' for initial support for Extended Instruction Support,
570 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
571 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
572 port->fun_prefix anymore (may change later),
573 (genFunction, genEndFunction): do not store/restore local registers for
574 _main (this should take care the --main-return command line option in
576 (genOr): removed some legacy pic-port instructions,
577 * src/pic16/genarith.c (genAddLit): re-enabled old code because
578 performing operations with SFR's causes data to be written more than
579 once to each SFR. Perhaps SFRs should be handled in special cases...
580 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
582 * src/pic16/main.c (_process_pragma): stack bound checking did not take
583 into account for stack starting position,
584 (struct OPTIONS pic16_optionsTable): added command line argument
585 --extended or -y for Extended Instruction Support,
586 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
587 (deassignLRs): *** perhaps the most important change, old 'for' code
588 (commented out for reference), didn't account for some registers which
589 were left marked 'not free' after a pointer operation. The change
590 reduces register usage a lot in some cases

2950 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2952 * device/lib/printf_large.c: removed inline assembly for portability and
2953 readability. Use printf_fast if speed or size are more important.
2954 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2955 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2957 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2959 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2960 prevent compiler warning
2962 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2964 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2965 moved to level 0 and declared as static. Also they are explicit
2966 placed in access bank. This was necessery because some times they
2967 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2968 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2969 optimizations. Currently only compare to unsigned char is implemented,
2970 * src/pic16/gen.c: added fReturnIdx array,
2971 * (struct resolvedIfx) is moved to gen.h and made public,
2972 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2973 * (aopForSym): added an optimization to directly store in stack of
2974 the operand of a SEND iCode,
2975 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2976 but as registers instead (AOP_REG) using the fReturnIdx array,
2977 * (pic16_freeAsmop): remove the freed register from the
2978 _G.sregsAlloc field,
2979 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2980 a compare of 'WREG',
2981 * (pic16_popGetTempRegCond): changed function prototype, now
2982 function takes also a bitVector argument v which holds the current
2983 set of registers that are allocated for stack access by aopForSym,
2984 registers allocated in aopForSym for accessing stack symbols are not
2985 any more part of the functions usedRegs field,
2986 * (genCall): some times aopOp is called for a stack variable to be
2987 send, aopForSym might perform the push, if this is true make sure
2988 that genCall doesn't push the variable twice by testing _G.resDirect,
2989 * (genFunction): changed testing for unspecified interrupt number
2990 from 256 to INTNO_UNSPEC,
2991 * modified selection scheme of frame pointer generation. Previously
2992 if function did use local registers a frame pointer was generated,
2993 now a frame pointer is generated only if function has arguments
2994 (that need PLUSW2 register access), or has stack arguments, or the
2995 compiler is not instructed to omit the frame pointer,
2996 * (genEndFunction): before restoring local registers that were saved
2997 in the function preamble, also restore the registers that *might*
2998 have been allocated for stack access,
2999 * (genRet): removed some old comments,
3000 * (genCmp, the active (RN's) version): added a call to the
3001 pic16_genCmp_special function to perform the compare with a more
3002 robust and optimized way,
3003 * (genInline): a feature has been added in inline code generation,
3004 which allows a wildcard variable substitution when writing inline
3005 assembly. Code is incomplete and experimental therefore undocumented,
3006 * (genCast): changed order of aopOp for result and right to allow
3007 aopForSym to directly load the result if possible,
3008 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3009 perform an optimized compare on some selected special occasions,
3010 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3011 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3012 generate an IVT any more,
3013 * src/pic16/main.c (pic16_optionsTable): added command line option
3015 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3016 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3018 * src/pic16/NOTES: Raphael Neider added in list of active developers
3019 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3020 jumptable_end to prevent bug #,
3021 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3022 inCond and outCond fields,
3023 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3024 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3025 turn off register spilling,
3026 * (packRegsForOneUse): synced with other ports' versions although it
3027 is not used currently,
3028 * (pic16_packRegisters): added an optimization while reading

3676 Adding support for replacing ljmps with sjmps in jumptables
3677 generated for switch statements. For now you need to set the
3678 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3679 Now 4 algorithms for mcs51 jumptable generation are used:
3680 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3681 addresses loaded pc-relative for up to 112 cases and stack-pushing
3682 target addresses loaded with offset from dptr for up to 256 cases.

3712 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3714 * added libc directory. The current version of LibC contains string
3715 functions, ctype functions and macros and some functions of the
3716 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3717 be extensively tested in the future. Standard disclaimer here.
3718 Library is not automatically build yet. But one can build it by
3719 invoking 'make' inside the libc directory.

3730 * (pic16_storeForReturn): optimized return of 0,
3731 * (genCmp): experimental code for new genCmp which uses PIC18's
3732 special compare&skip instructions. Initial tests fail some times
3733 with variables grater than 1 byte in size, so new code is disabled,
3734 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3736 * (genCast): began a fix to optimize the casting of a bit to another
3737 bit, now assigning a bitfield to another bitfield will fail, sorry,

3746 and 1 for banking instruction,
3747 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3748 caused stop processing pCodes after a inline assembly block,
3749 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3751 registers when it shouldn't,
3752 * src/pic16/ralloc.c (allocReg): add preliminary support for
3753 supporting a limited set of temporary registers,
3755 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6763 loaded with the linker search paths (-L arguments) and the libraries
6764 to be linked with the current source (-l arguments). Changes
6765 currently will affect only the pic16 port.
6766 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6767 include path the port specific paths and port specific libraries,
6768 * gplink command now contains the $3 argument,
6769 * src/pic16/device.h,

6786 Documenting changes from previous commits.
6787 * configure.in (version 1.56),
6788 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6789 when generating output files to configure the pic16 library,
6790 but now I've commented it out, since gputils aren't installed in the
6791 SF compile farm, so library won't compile
6793 * device/lib/Makefile.in (version 1.56): initially I've added in
6794 target 'all' the prerequestive 'model-pic16' so it compiled the
6795 pic16 library, but now I've commented it out for the same reasons
6797 * added targets 'model-pic16' and 'objects-pic16' to compile the
6799 * added target 'port-specific-objects-pic16' to handle the
6800 generated libraries and copy them into the build/ directory
6801 * added target 'clean-intermediate-pic16' to clean intermediate
6802 files into pic16 directory
6803 * in target 'installdirs' added line to create directory pic16 in

6807 added lines to copy all header files to installation path,
6808 * in target 'installdirs' added line create directory for pic16
6809 headers in the installation path

7040 * as/mcs51/lkmain.c: Help about -Y option
7041 * as/mcs51/lkarea.c: Fixed gcc warnings
7043 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7045 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
7047 * support/valdiag/tests/overflow.c: added
7048 * src/SDCCast.c (decorateType),
7049 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7050 LEFT_OP (left shift)
7052 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7054 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7055 (default behaviour).
7057 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7059 A python script to validate compiler diagnostic messages. It can be
7060 used to verify that sdcc complains about bad c source code and
7061 gives a good location of the error.
7062 * support/valdiag/Makefile,
7063 * support/valdiag/valdiag.py,
7064 * support/valdiag/tests/*
7066 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7068 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7069 * src/SDCCsymt.c (newEnumType),
7071 * support/Util/SDCCerr.c,
7072 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7074 * support/regression/tests/enum.c: added test for enum values that
7075 require at least 2 bytes of storage.
7077 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7079 * src/common.h: added ifndef/define/endif macros
7080 around the header file.
7081 Bug reported from Jesus Calvino-Fraga
7083 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7085 * sdcc.spec: updated
7086 * device/include/Makefile.in: don't install CVS directories
7087 * device/lib/Makefile.in: added removal of CVS directories after install
7088 * doc/Makefile: fixed install, added local_icons
7089 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7090 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7091 * src/ds390/gen.c (genRightShift): fixed bug #870788
7092 * src/SDCCast.c (decorateType): fixed bug #870781
7094 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7096 PIC16 port related changes:
7097 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7098 added variable stackPos,
7100 * gen.c: genCall, assignResultValue: added support for
7101 pushing/retrieving function parameters to/from stack,
7102 genFunction,genEndFunction: setup stack frame for the
7104 genAddrOf: will be changed according to bug 863624
7106 * added files genutils.c and genutils.h which contain gen*
7107 debugged and optimised functions extracted from gen.c
7109 * glue.c: added variable 'externs' which holds extern symbols,
7110 pic16emitRegularMap: is modified to properly handle relocatable
7111 symbols under the new scheme,
7112 pic16createInterruptVect: is modified
7113 pic16printPublics: is modified to emit 'global' assembler directives,
7114 added pic16_printExterns to print extern symbols,
7115 pic16glue: initializes stack/frame pointer in the beginning of
7116 the assembly output. Temporary hack, will be corrected later,
7117 because gplink yet does not support stack and SDCC does not
7118 yet support a type of crt0.o object to create the final binary.
7120 * Removed many lines that contain 8051 legacy code.
7121 * The code is finally placed under a 'code' directive.
7122 * Added port specific options.
7124 * _process_pragma: simplified since now we do not need *special*
7125 include file to define SFR registers. But a separate header
7126 will be needed. This will be developed later.
7127 * _pic16_parseOptions: added, parses port specific options:
7128 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7129 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7130 --preplace-udata-with=
7132 * _pic16_setDefaultOptions: modified to initialize section names,
7133 but hack is temporarly out of order since it needs improvement.
7134 * _pic16_genAssemblerPreamble: configuration words are emitted by
7135 their address instead of their name. This part is incomplete and
7136 supports only the 18Fxx2 devices. Other devices will emit an error
7137 during assembly since they do not contain the same set of config
7139 * _pic16_genIVT: is modified,
7141 * pcode.c: added definitions for some hardware registers that are needed
7143 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7144 All PCI entries are updated. Now LFSR is supported.
7145 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7146 * added pic16_newpCodeOpLit2 to support instructions with
7147 two literal arguments
7148 * pic16_pCode2str: corrected code that emits assembler instructions
7149 with two literal operands and those that have an access bit modifier
7150 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7151 this fixes a bug which caused some labels to be lost, when an
7152 assembler directive was added, i.e. banksel,
7153 * pic16_FixRegisterBanking: improved logic that causes the insertion
7155 * InlineFunction: functions that are called once, are not any more
7156 inlined. This can be a port option in the future,
7158 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7160 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7161 hold the corresponding uninitialized symbols,
7162 * pic16_allocProcessorRegister: registers have explicit marked the
7164 * pic16_allocInternalRegister: registers are explicit marked as
7166 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7167 processing list, so bit registers were lost,
7170 * ralloc.h: added field 'accessBank' and original symbol operand
7171 in register definition,
7172 * removed the field isMapped from register definition,
7174 ** Several functions have been removed from various sources:
7175 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7176 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7177 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7178 pic16_assignRelocatableRegisters
7180 ** others have been introduced:
7181 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7182 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7184 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7186 * support/scripts/inc2h.pl: changed definition of BIT_AT
7187 to emit 'sbit at' instead of 'bit at'. This was a request.
7189 PIC16 port related preliminary changes:
7190 * gen.c: prefixed function popRegFromString with
7191 pic16_ and all references to it corrected
7192 * pcode.c: all pic16_pc_* hardware registers prefixed
7193 with underscore (_),
7194 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7195 * ralloc.c: newReg(): when register is REG_SFR then
7196 set address to rIdx,
7197 pic16_allocProcessorRegister(): marks register wasUsed=0
7198 pic16_writeUsedRegs(): added a call to assign processor
7199 registers via pic16_assignFixedRegisters
7201 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7203 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7204 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7205 variables in unused register banks. Also the SSEG is placed
7206 wherever there is enough space for it, and IDATA can be anywhere
7207 in internal RAM. For now compile using -Wl-Y[stack_size].
7208 The mem file is different for this option as well, since it
7209 makes no sense of talking about DSEG lenght.
7211 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7213 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7214 in certain cases, e.g. when ROM assignment, patch provided
7215 from Albert den Haan.
7217 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7360 * src/mcs51/peephole.def,
7361 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7362 (allows non-interrupt and interrupt code to safely compete for a resource

7373 multiply defined with mismatching "at" address.
7375 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7377 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
7378 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

7456 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7458 * src/SDCCast.c (decorateType): disabled a transformation I added in
7459 revision 1.188 (access to fields of a structure at an absolute address);
7460 it breaks with bitfields, extern declarations, and gcse analysis.
7461 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7462 could be assigned through a pointer, so don't complain.
7463 * src/SDCCast.c (astErrors),
7465 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8102 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8103 support for standard C idiom of memory mapped variables; for
8104 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8105 to xdata int at 0x1234 tempvar = 1.
8106 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8107 provided by Akiya ISHIDA

8123 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8125 Fixed bug #621531 (const & volatile confusion in the type chain).
8126 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8127 refer to the const or volatile state of the pointer itself.

8218 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8219 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8220 fetching of the pointer
8221 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8222 copied from genNearPointerSet()
8223 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8224 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8225 If they pop r0/r1 they must be called in the opposite order than aopOp().
8226 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8227 (resp. --stack-auto), prepared for --xstack

8238 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8240 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8241 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8242 type for bits was changed. It resulted in bit variables becoming
8243 global, which is not permitted in PIC 14 assembly output.
8245 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8247 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8249 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8251 Z80 and MCS51 linkers complaint if a public symbol is defined

8260 A few small changes that speed up the peephole optimizer.
8264 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8266 Try to make the peephole optimizer smarter by maintaining
8267 an association between the assembly source code and the
8268 iCodes that originated them. Put this information to use
8269 with a new peephole rule condition "notVolatile" so that
8270 the rules can be aggressive yet still safe.
8275 * src/mcs51/peeph.def
8277 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8281 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8282 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8283 if the left or right operand symbols have the accuse flag set.
8285 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8287 Changed the type of the result of the ! (NOT) operator to char;
8288 previously it returned the same type as the source. This allows
8289 us to eliminate all the genFloatNot functions (all of its target
8290 implementations were very buggy) since !float can use the same
8293 * src/SDCCicode.c (ast2iCode): ! returns char
8294 * src/mcs51/gen.c (genNot, genNotFloat),
8295 * src/ds390/gen.c (genNot, genNotFloat),
8296 * src/z80/gen.c (genNot, genNotFloat),
8297 * src/pic/gen.c (genNot, genNotFloat),

8300 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8302 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8303 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8304 during interrupts. Ensure WSAVE is located at a shared bank address.
8305 2. Fixed page selection in some places
8306 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8307 the registers name strings.
8308 4. Fixed "signed / unsigned compare" compiler warnings.
8309 5. The PIC port manages its own allocation of the general purpose
8310 registers, but makes no attempt to reuse them. As a result when
8311 compiling it soon runs out of general purpose registers. Some
8312 additional code was added to the files pcode.c and device.c to walk
8313 through the function call tree and rename the registers so that they
8323 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8324 genPlus() & genMinus() when the result is the same as left or right
8326 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8330 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8332 Made bitfield a distinct type from bit so that bitfields
8333 convert as per ANSI C and bits retain their traditional
8334 boolean style behaviour. Implemented bitfield support in
8342 * src/ds390/gen.c: bit v bitfield split
8343 * src/z80/gen.c: New support for bitfields
8344 * support/regression/tests/bitfields.c: reenabled z80,
8347 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8349 Rules 246.x, 247.x relate to bitfields, the others speed up
8350 access to xdata mapped I/O devices.
8352 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8354 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8356 Cleaned up genPackBits and genUnpackBits and added two helper
8357 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8358 for literal assignments in genPackBits (thanks to Frieder for
8364 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8366 Fixed bug #748310 (pointer to function type mishandled when the
8367 function name is omitted). Also fixed a SIGSEGV when a function
8368 attribute (reentrant, etc) is used on a non-function or on a
8369 function but misplaced before the parameter list.
8371 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8373 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8374 * support/Util/SDCCerr.h,
8375 * support/Util/SDCCerr.c: Added func attr misuse error msg

8396 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8398 Made the constant following the "interrupt" keyword optional. If
8399 omitted, the function will not automatically be given an entry
8400 in the interrupt vector table (similar to #pragma NOIV, but
8401 less syntacticly kludgy). The interrupt number is also now
8402 range checked. Also fixed a bug in the high order bit example

8410 * support/Util/SDCCerr.h
8413 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8415 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8416 * src/SDCCicode.c (operandOperation): rewritten some ops
8417 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8418 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8420 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8421 be re-activated by defining REDUCE_LITERALS)
8422 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8423 unsigned, but are signed by default
8424 * src/SDCCval.c (constVal): rearranged
8425 * src/SDCCval.c (valMod): preliminary fix
8426 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8468 constants are unsigned; added recognition of "u" flag for unsigned
8469 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8470 * src/SDCCval.c (valDiv, valMod): fixed signdness
8471 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8472 signedness of modulo, left and right shift

8932 added if/endif conditional macros to remove options help
8933 messages from optionsTable when a port is not configured, added
8934 support for the PIc16 port in the ports table, when executing
8935 the compiler with no port specified on command line, a default
8936 port is selected with the new macro DEFAULT_PORT which is
8937 defined in port.h, in setDefaultOptions() linkOptions is removed
8938 from initialization assignment, since now it is a set,
8939 parseCmdLine uses setParseWithComma for linkOptions, in
8940 linkEdit() linkOptions are accessed with new function indexSet()
8941 which returns the i'th item of a set variable. See SDCCset.c, in
8942 linkEdit() when calling buildCmdLine(), added linkOptions as
8943 last argument. Now users can pass arguments to gplink via the
8944 -Wl option, main() uses pic16glue() to glue up pic16 programs

8958 gpasm complaining and test the linkage with gplink, _linkCmd and
8959 _asmCmd changed to be more gplink and gpasm friendly
8960 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8961 produced an error when parsed, peep rule 12 is added to utilize
8962 movff, but it is commented out since the pCode does not support
8963 yet a command with 2 address arguments
8965 2003-05-18 <johan AT balder>
8967 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8994 2003-05-11 Borut Razem <borut.razem AT siol.net>
8996 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10000 2003-01-06 <johan AT balder>
10002 * src/SDCCicode.c: fixed array add
10004 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10005 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10006 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10008 2003-01-04 <johan AT balder>
10010 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10012 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10013 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10015 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10016 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10017 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10019 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10020 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10022 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10023 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10025 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10026 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10028 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10030 * in \sdcc\as\mcs51\ changed these files in order to create an
10031 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10032 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10033 following files to include the previous two files: aslink.dsp,
10034 Makefile.aslink, Makefile.bcc, and Makefile.in.
10036 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10037 .adb instead of .cdb
10039 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10041 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10042 value from option --iram-size.
10044 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10046 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10049 2002-09-18 <wiml AT hhhh.org>
10051 * SDCClrange.h: exposed setFromRange() and setToRange()
10052 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10053 packRegsForAccUse() (bug 542397)
10054 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10055 multiple times and emitting the fetch operations more than once
10056 added aopGetUsesAcc() function to allow binary operators to
10057 fetch their operands in the correct order; made genMinus() emit
10058 compact code for X = LITERAL - Y
10060 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10061 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10062 sprintf() in line 1267.
10064 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10065 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10068 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10069 Changes to aslink (All the changes are marked with 'JCF'):
10071 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10074 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10075 area BSEG. Also moves, if possible, the DATA area down into the internal
10076 ram so more space is available.
10078 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10081 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10082 not bytes. Function summary() which creates a memory usage summary
10083 file with extension .mem. Reports of overlaping stack and small stack
10084 size. If the space for the stack is less than 16 bytes aslink trows a
10087 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10088 the 8051. Option 'y' for memory summary output file.
10090 Changes to sdcc (All the changes are marked with 'JCF'):
10092 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10094 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10095 overlaying area for it (uses RegBankUsed[4]).
10097 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10098 bank zero as used by default. By default aslink locates the stack
10099 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10100 the creation of the .mem file. Delegates the allocation of data area
10101 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10102 the begining of the stack area to aslink.
10104 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10105 glue() in SDCCglue.c creates an area for it.
10107 2002-09-03 Borut Razem <borut.razem AT siol.net>
10108 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10109 sdcc/src/pic/glue.c:
10110 introduced atexit() handler for teporay files removal in case of
10111 errors, assertions, ...
10113 2002-08-29 Borut Razem <borut.razem AT siol.net>
10114 * sdcc/support/cpp2/auto-host_vc_in.h:
10115 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10116 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10117 Maybe there is a similar problem with BORLANDC? It should be checked!
10119 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10120 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10121 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10122 was not executed, and the compiler (cl) launched a warning:
10123 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10125 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10126 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10128 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10129 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10131 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10132 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10133 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10134 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10135 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10136 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10137 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10138 - added Release configuration in VS projects
10139 - review of compiler an linker options
10140 - VC .exe files are generated in bin_vc directory, not to interfere
10141 with binaries generated from other projects (cygwin, mingw, bcc ...)
10143 * sdcc/src/yacc.dsp: added
10145 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10146 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10147 and insert the version number definitions from .version
10149 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10151 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10152 added - genarate auto-host.h using auto-host_vc_in.h as template
10155 removed from CVS, generated automatically
10157 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10158 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10160 2002-08-11 Borut Razem <borut.razem AT siol.net>
10161 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10163 2002-08-10 Borut Razem <borut.razem AT siol.net>
10164 * src/SDCCmain.c (main):
10165 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10166 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10167 The consequence was that some temporary files were not removed.
10170 unification of code in functions tempfilename() and tempfile():
10171 function tempnam() is defined in Visual Studio 6.0 and .NET
10173 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10175 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10176 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10177 - removed compiler command line option /WX: Treats all warnings as errors
10178 - update a list of source files, included into the project
10180 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10181 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10182 changed project type to Generic Project so that can be correcly converted to VS.NET project
10184 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10186 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10188 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10190 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10191 added return 0 statements after assert() to make compiler happy
10193 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10194 added newline in the def file to keep MSC compiler satisfied
10196 * sdcc/src/z80/gen.c:
10197 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10198 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10199 - solved MSC error in function aopDump()
10201 * sdcc_vc.h: define PREFIX as "\\sdcc"
10203 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10204 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10207 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10208 - Rewrote the register banking algorithm.
10209 - Added pCode live-range analysis to registers (for now, only non-used and
10210 singly-used registers optimized away)

10237 * src/z80/main.c: Added force callee saves for jaune.
10239 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10241 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10243 2002-03-28 Johan Knol <johan AT balder>
10245 * src/SDCCval.c: fixed bug #532436
10247 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10249 Added "char *Processor" field to the port structure.
10252 Added -p option. Allows port dependent processor to be specified.
10255 Initialized the new field char *Processor field to NULL in all ports
10258 Compiler generated registers for interrupt context saving
10259 were not getting allocated.
10261 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10264 Fixed left shift. Will promote the left side of a left shift
10265 if a) left shifting more than size of operand or b) when assigned
10266 to something size > size of left side
10268 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10270 tons of changes. Register allocation has been
10271 rewritten. Added customization for the various PICs. Flow
10272 analysis is restructured. ...
10274 * src/pic/device.h:
10277 * src/pic/device.c:
10278 Added. device.c is a PIC port hack to accomodate variations
10281 2002-03-13 Michael Hope <michaelh AT vroom>
10283 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10285 2002-03-04 johanknol <johanknol AT manik>
10287 * /src/SDCCval.c: fixed
10289 const unsigned char arr[][2] = { { 0, 1 } };

10376 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10378 * sdcc/src/SDCCloop.c:
10379 Previous fix was not good. basic blocks that have "break" or "return" are
10380 not really partof a loop , but live ranges used in these blocks should
10381 be live thru the entire loop, so set partOfLoop but don't add them to
10384 2002-02-21 <johan AT FRIJA>
10386 * src/SDCCcse.c: fixed bug #514308
10388 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10391 Fixed BUG #519583. If a conditional block ended in a return/break
10392 statement inside a loop, it was not being considered part of the loop.
10394 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10396 2002-02-10 Karl Bongers <karl AT turbobit.com>

10410 Took out debug printfs in ucsim "next" command.
10412 * sim/ucsim/xa.src:
10413 Karl and Johan start ucsim XA support. Most dissassembly working,
10414 about 75% emulation done(plenty of work remaining).
10416 * sim/ucsim/z80.src:
10417 Add Z80 support to ucsim, add test-ucz80 regression test,
10418 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10419 Notice z80 compiler fails on examples/test3.c/crc code.
10421 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

10433 3) added __builtin_swapw swap bytes of a short
10435 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10436 1) handle multiple send & receives from register bank1
10437 2) ralloc can now allocate DPTR1 to some liveRanges
10439 * src/SDCCsymt.c, src/SDCCsymt.h:
10440 changes to handle multiple sends & receives
