999 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1000 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1002 One basic decision: e.g. src/clean.mk includes further files. In order
1003 to make this work there are two solutions:
1004 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1005 run configure on them. This way they can use
1006 'include $(srcdir)/port-clean.mk'
1007 - always include clean.mk by the Makefile at the same level. To avoid
1008 that `make clean` tries to include and build Makefile.dep the
1009 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1010 implemented, because now even `make uninstall` doesn't create
1011 Makefile.in. clean.mk could be eliminated by pasting it in
1014 * debugger/mcs51/Makefile.in: build own objects from library sources
1015 (SLIB, SDCC) in current directory
1017 * configure, configure.in: renamed --disable-device-lib-build in
1018 --disable-device-lib; added --enable-doc, the required tools are
1019 searched by configure; added result message; the toolchain for the
1020 belonging ports are now only built, if the port is enabled.
1022 * support/regression/*: all output is written in directory gen, because
1023 the fwk and ports directories don't livet in the build tree using vpath
1025 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1026 --disable-device-lib, added --enable-doc, added section VPATH
1028 * sim/ucsim/configure.in,
1029 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1030 z80 are enabled by default
1032 2006-04-24 Raphael Neider <rneider AT web.de>
1034 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1035 to config word, "pic14_"-prefixed some extern functions
1036 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1037 config word has been found
1038 * src/pic/device.h: added prototypes
1039 * src/pic/pcode.c: added "pic14_"-prefix where needed

1306 (genCritical, genEndCritical): added functions
1307 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1308 * src/z80/mappings.i: added "ei" to all mappings

1320 the left operand is shorter than the result (c* = lit-c* + int),
1322 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1325 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1327 * src/.version: increased version number to 2.5.5
1328 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1329 linking is done manually in pic16 port's _linkEdit,
1330 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1331 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1332 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1333 allocate asmop as AOP_ACC,
1334 (aopForRemat): added parameter 'bool result' in function declaration,
1335 (pic16_aopGet): return AOP_ACC when accessing WREG,

1347 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1348 call to allocReg, not by manually allocating a new one,
1349 (pic16_assignRegisters): now before going through the register
1350 allocating functions mark all registers as free. This eliminates some
1351 side effects resulting from peephole parser done earlier in the backbone
1353 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1355 * src/SDCCicode.c (geniCodeLogic),

1406 made the linker quiet
1408 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1410 * src/pic16/gen.c (genPcall): fixed bug #1443644
1411 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1412 which dumps before the function entry point a data byte which represents
1413 the number of the local variables used by the specified function, added
1414 'xinst' for initial support for Extended Instruction Support,
1415 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1416 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1417 port->fun_prefix anymore (may change later),

1421 (genOr): removed some legacy pic-port instructions,
1422 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1423 performing operations with SFR's causes data to be written more than

1430 --extended or -y for Extended Instruction Support,
1431 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1432 (deassignLRs): *** perhaps the most important change, old 'for' code
1433 (commented out for reference), didn't account for some registers which
1434 were left marked 'not free' after a pointer operation. The change
1435 reduces register usage a lot in some cases

3710 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3711 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3712 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3713 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3714 always available in leading double underscore form. The C99 support is

3793 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3795 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3797 * device/lib/printf_large.c: removed inline assembly for portability and
3798 readability. Use printf_fast if speed or size are more important.
3799 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3800 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3802 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3804 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3805 prevent compiler warning
3807 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3809 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3810 moved to level 0 and declared as static. Also they are explicit
3811 placed in access bank. This was necessery because some times they
3812 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3813 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3814 optimizations. Currently only compare to unsigned char is implemented,
3815 * src/pic16/gen.c: added fReturnIdx array,
3816 * (struct resolvedIfx) is moved to gen.h and made public,
3817 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3818 * (aopForSym): added an optimization to directly store in stack of
3819 the operand of a SEND iCode,
3820 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3821 but as registers instead (AOP_REG) using the fReturnIdx array,
3822 * (pic16_freeAsmop): remove the freed register from the
3823 _G.sregsAlloc field,
3824 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3825 a compare of 'WREG',
3826 * (pic16_popGetTempRegCond): changed function prototype, now
3827 function takes also a bitVector argument v which holds the current
3828 set of registers that are allocated for stack access by aopForSym,
3829 registers allocated in aopForSym for accessing stack symbols are not
3830 any more part of the functions usedRegs field,
3831 * (genCall): some times aopOp is called for a stack variable to be
3832 send, aopForSym might perform the push, if this is true make sure
3833 that genCall doesn't push the variable twice by testing _G.resDirect,
3834 * (genFunction): changed testing for unspecified interrupt number
3835 from 256 to INTNO_UNSPEC,
3836 * modified selection scheme of frame pointer generation. Previously
3837 if function did use local registers a frame pointer was generated,
3838 now a frame pointer is generated only if function has arguments
3839 (that need PLUSW2 register access), or has stack arguments, or the
3840 compiler is not instructed to omit the frame pointer,
3841 * (genEndFunction): before restoring local registers that were saved
3842 in the function preamble, also restore the registers that *might*
3843 have been allocated for stack access,
3844 * (genRet): removed some old comments,
3845 * (genCmp, the active (RN's) version): added a call to the
3846 pic16_genCmp_special function to perform the compare with a more
3847 robust and optimized way,
3848 * (genInline): a feature has been added in inline code generation,
3849 which allows a wildcard variable substitution when writing inline
3850 assembly. Code is incomplete and experimental therefore undocumented,
3851 * (genCast): changed order of aopOp for result and right to allow
3852 aopForSym to directly load the result if possible,
3853 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3854 perform an optimized compare on some selected special occasions,
3855 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3856 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3857 generate an IVT any more,
3858 * src/pic16/main.c (pic16_optionsTable): added command line option
3860 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3861 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3863 * src/pic16/NOTES: Raphael Neider added in list of active developers
3864 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3865 jumptable_end to prevent bug #,
3866 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3867 inCond and outCond fields,
3868 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3869 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3870 turn off register spilling,
3871 * (packRegsForOneUse): synced with other ports' versions although it
3872 is not used currently,
3873 * (pic16_packRegisters): added an optimization while reading
3874 structure bitfields, some registers may be saved (malloc code is
3875 decreased by 80 bytes)
3877 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3879 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3880 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3881 this can be optimized more?
3883 2005-03-10 Raphael Neider <rneider AT web.de>
3885 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3886 genNearPointerGet): (hopefully) fixed access to bitfields via

4521 Adding support for replacing ljmps with sjmps in jumptables
4522 generated for switch statements. For now you need to set the
4523 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4524 Now 4 algorithms for mcs51 jumptable generation are used:
4525 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4526 addresses loaded pc-relative for up to 112 cases and stack-pushing
4527 target addresses loaded with offset from dptr for up to 256 cases.

4557 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4559 * added libc directory. The current version of LibC contains string
4560 functions, ctype functions and macros and some functions of the
4561 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4562 be extensively tested in the future. Standard disclaimer here.
4563 Library is not automatically build yet. But one can build it by
4564 invoking 'make' inside the libc directory.

4575 * (pic16_storeForReturn): optimized return of 0,
4576 * (genCmp): experimental code for new genCmp which uses PIC18's
4577 special compare&skip instructions. Initial tests fail some times
4578 with variables grater than 1 byte in size, so new code is disabled,
4579 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4581 * (genCast): began a fix to optimize the casting of a bit to another
4582 bit, now assigning a bitfield to another bitfield will fail, sorry,
4583 * src/pic16/main.c: disabled the use of lr-support feature,
4584 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4590 * (isBankInstruction): modified to return 0 for no banking instruction,
4591 and 1 for banking instruction,
4592 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4593 caused stop processing pCodes after a inline assembly block,
4594 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4595 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4596 registers when it shouldn't,
4597 * src/pic16/ralloc.c (allocReg): add preliminary support for
4598 supporting a limited set of temporary registers,
4600 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4606 (genFunction): optimize RECEIVE iCodes in reentrant functions
4608 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7608 loaded with the linker search paths (-L arguments) and the libraries
7609 to be linked with the current source (-l arguments). Changes
7610 currently will affect only the pic16 port.
7611 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7612 include path the port specific paths and port specific libraries,
7613 * gplink command now contains the $3 argument,

7631 Documenting changes from previous commits.
7632 * configure.in (version 1.56),
7633 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7634 when generating output files to configure the pic16 library,
7635 but now I've commented it out, since gputils aren't installed in the
7636 SF compile farm, so library won't compile
7638 * device/lib/Makefile.in (version 1.56): initially I've added in
7639 target 'all' the prerequestive 'model-pic16' so it compiled the
7640 pic16 library, but now I've commented it out for the same reasons
7642 * added targets 'model-pic16' and 'objects-pic16' to compile the
7644 * added target 'port-specific-objects-pic16' to handle the
7645 generated libraries and copy them into the build/ directory
7646 * added target 'clean-intermediate-pic16' to clean intermediate
7647 files into pic16 directory
7648 * in target 'installdirs' added line to create directory pic16 in

7897 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7899 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7900 (default behaviour).
7902 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7904 A python script to validate compiler diagnostic messages. It can be
7905 used to verify that sdcc complains about bad c source code and
7906 gives a good location of the error.
7907 * support/valdiag/Makefile,
7908 * support/valdiag/valdiag.py,
7909 * support/valdiag/tests/*
7911 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7913 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7914 * src/SDCCsymt.c (newEnumType),
7916 * support/Util/SDCCerr.c,
7917 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7919 * support/regression/tests/enum.c: added test for enum values that
7920 require at least 2 bytes of storage.
7922 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7924 * src/common.h: added ifndef/define/endif macros
7925 around the header file.
7926 Bug reported from Jesus Calvino-Fraga
7928 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7930 * sdcc.spec: updated
7931 * device/include/Makefile.in: don't install CVS directories
7932 * device/lib/Makefile.in: added removal of CVS directories after install
7933 * doc/Makefile: fixed install, added local_icons
7934 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7935 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7936 * src/ds390/gen.c (genRightShift): fixed bug #870788
7937 * src/SDCCast.c (decorateType): fixed bug #870781
7939 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7941 PIC16 port related changes:
7942 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7943 added variable stackPos,
7945 * gen.c: genCall, assignResultValue: added support for
7946 pushing/retrieving function parameters to/from stack,
7947 genFunction,genEndFunction: setup stack frame for the
7949 genAddrOf: will be changed according to bug 863624
7951 * added files genutils.c and genutils.h which contain gen*
7952 debugged and optimised functions extracted from gen.c
7954 * glue.c: added variable 'externs' which holds extern symbols,
7955 pic16emitRegularMap: is modified to properly handle relocatable
7956 symbols under the new scheme,
7957 pic16createInterruptVect: is modified
7958 pic16printPublics: is modified to emit 'global' assembler directives,
7959 added pic16_printExterns to print extern symbols,
7960 pic16glue: initializes stack/frame pointer in the beginning of
7961 the assembly output. Temporary hack, will be corrected later,
7962 because gplink yet does not support stack and SDCC does not
7963 yet support a type of crt0.o object to create the final binary.
7965 * Removed many lines that contain 8051 legacy code.
7966 * The code is finally placed under a 'code' directive.
7967 * Added port specific options.
7969 * _process_pragma: simplified since now we do not need *special*
7970 include file to define SFR registers. But a separate header
7971 will be needed. This will be developed later.
7972 * _pic16_parseOptions: added, parses port specific options:
7973 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7974 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7975 --preplace-udata-with=
7977 * _pic16_setDefaultOptions: modified to initialize section names,
7978 but hack is temporarly out of order since it needs improvement.
7979 * _pic16_genAssemblerPreamble: configuration words are emitted by
7980 their address instead of their name. This part is incomplete and
7981 supports only the 18Fxx2 devices. Other devices will emit an error
7982 during assembly since they do not contain the same set of config
7984 * _pic16_genIVT: is modified,
7986 * pcode.c: added definitions for some hardware registers that are needed
7988 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7989 All PCI entries are updated. Now LFSR is supported.
7990 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7991 * added pic16_newpCodeOpLit2 to support instructions with
7992 two literal arguments
7993 * pic16_pCode2str: corrected code that emits assembler instructions
7994 with two literal operands and those that have an access bit modifier
7995 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7996 this fixes a bug which caused some labels to be lost, when an
7997 assembler directive was added, i.e. banksel,
7998 * pic16_FixRegisterBanking: improved logic that causes the insertion
8000 * InlineFunction: functions that are called once, are not any more
8001 inlined. This can be a port option in the future,
8003 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8005 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8006 hold the corresponding uninitialized symbols,
8007 * pic16_allocProcessorRegister: registers have explicit marked the
8009 * pic16_allocInternalRegister: registers are explicit marked as
8011 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8012 processing list, so bit registers were lost,
8015 * ralloc.h: added field 'accessBank' and original symbol operand
8016 in register definition,
8017 * removed the field isMapped from register definition,
8019 ** Several functions have been removed from various sources:
8020 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8021 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8022 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8023 pic16_assignRelocatableRegisters
8025 ** others have been introduced:
8026 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8027 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8029 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8031 * support/scripts/inc2h.pl: changed definition of BIT_AT
8032 to emit 'sbit at' instead of 'bit at'. This was a request.
8034 PIC16 port related preliminary changes:
8035 * gen.c: prefixed function popRegFromString with
8036 pic16_ and all references to it corrected
8037 * pcode.c: all pic16_pc_* hardware registers prefixed
8038 with underscore (_),
8039 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8040 * ralloc.c: newReg(): when register is REG_SFR then
8041 set address to rIdx,
8042 pic16_allocProcessorRegister(): marks register wasUsed=0
8043 pic16_writeUsedRegs(): added a call to assign processor
8044 registers via pic16_assignFixedRegisters
8046 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8048 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8049 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8050 variables in unused register banks. Also the SSEG is placed
8051 wherever there is enough space for it, and IDATA can be anywhere
8052 in internal RAM. For now compile using -Wl-Y[stack_size].
8053 The mem file is different for this option as well, since it
8054 makes no sense of talking about DSEG lenght.
8056 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8058 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8059 in certain cases, e.g. when ROM assignment, patch provided
8060 from Albert den Haan.
8062 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8301 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8303 * src/SDCCast.c (decorateType): disabled a transformation I added in
8304 revision 1.188 (access to fields of a structure at an absolute address);
8305 it breaks with bitfields, extern declarations, and gcse analysis.
8306 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8307 could be assigned through a pointer, so don't complain.
8308 * src/SDCCast.c (astErrors),
8310 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8947 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8948 support for standard C idiom of memory mapped variables; for
8949 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8950 to xdata int at 0x1234 tempvar = 1.
8951 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8952 provided by Akiya ISHIDA

8968 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8970 Fixed bug #621531 (const & volatile confusion in the type chain).
8971 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8972 refer to the const or volatile state of the pointer itself.

9037 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9038 pcoderegs.h, ralloc.c, ralloc.h
9039 * main.c: added top header and GPL license notice

9053 aren't part of the nRegs tally.
9055 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9057 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9063 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9064 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9065 fetching of the pointer
9066 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9067 copied from genNearPointerSet()
9068 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9069 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9070 If they pop r0/r1 they must be called in the opposite order than aopOp().
9071 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9072 (resp. --stack-auto), prepared for --xstack

9083 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9085 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9086 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9087 type for bits was changed. It resulted in bit variables becoming
9088 global, which is not permitted in PIC 14 assembly output.
9090 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9092 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9105 A few small changes that speed up the peephole optimizer.
9109 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9111 Try to make the peephole optimizer smarter by maintaining
9112 an association between the assembly source code and the
9113 iCodes that originated them. Put this information to use
9114 with a new peephole rule condition "notVolatile" so that
9115 the rules can be aggressive yet still safe.
9120 * src/mcs51/peeph.def
9122 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9126 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9127 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9128 if the left or right operand symbols have the accuse flag set.
9130 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9132 Changed the type of the result of the ! (NOT) operator to char;
9133 previously it returned the same type as the source. This allows
9134 us to eliminate all the genFloatNot functions (all of its target
9135 implementations were very buggy) since !float can use the same
9138 * src/SDCCicode.c (ast2iCode): ! returns char

9140 * src/ds390/gen.c (genNot, genNotFloat),
9141 * src/z80/gen.c (genNot, genNotFloat),
9142 * src/pic/gen.c (genNot, genNotFloat),

9145 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9147 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9148 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9149 during interrupts. Ensure WSAVE is located at a shared bank address.
9150 2. Fixed page selection in some places
9151 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9152 the registers name strings.
9153 4. Fixed "signed / unsigned compare" compiler warnings.
9154 5. The PIC port manages its own allocation of the general purpose
9155 registers, but makes no attempt to reuse them. As a result when
9156 compiling it soon runs out of general purpose registers. Some
9157 additional code was added to the files pcode.c and device.c to walk
9158 through the function call tree and rename the registers so that they
9168 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9169 genPlus() & genMinus() when the result is the same as left or right
9171 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9175 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9177 Made bitfield a distinct type from bit so that bitfields
9178 convert as per ANSI C and bits retain their traditional
9179 boolean style behaviour. Implemented bitfield support in
9187 * src/ds390/gen.c: bit v bitfield split
9188 * src/z80/gen.c: New support for bitfields
9189 * support/regression/tests/bitfields.c: reenabled z80,
9192 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9194 Rules 246.x, 247.x relate to bitfields, the others speed up
9195 access to xdata mapped I/O devices.
9197 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9199 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9201 Cleaned up genPackBits and genUnpackBits and added two helper
9202 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9203 for literal assignments in genPackBits (thanks to Frieder for
9209 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9211 Fixed bug #748310 (pointer to function type mishandled when the
9212 function name is omitted). Also fixed a SIGSEGV when a function
9213 attribute (reentrant, etc) is used on a non-function or on a
9214 function but misplaced before the parameter list.
9216 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9218 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9219 * support/Util/SDCCerr.h,
9220 * support/Util/SDCCerr.c: Added func attr misuse error msg
9222 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9224 Fixed bug #787649 by anonymous
9225 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9241 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9243 Made the constant following the "interrupt" keyword optional. If
9244 omitted, the function will not automatically be given an entry
9245 in the interrupt vector table (similar to #pragma NOIV, but
9246 less syntacticly kludgy). The interrupt number is also now
9247 range checked. Also fixed a bug in the high order bit example

9255 * support/Util/SDCCerr.h
9258 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9260 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9261 * src/SDCCicode.c (operandOperation): rewritten some ops
9262 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9263 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9265 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9266 be re-activated by defining REDUCE_LITERALS)
9267 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9268 unsigned, but are signed by default
9269 * src/SDCCval.c (constVal): rearranged
9270 * src/SDCCval.c (valMod): preliminary fix
9271 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9313 constants are unsigned; added recognition of "u" flag for unsigned
9314 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9315 * src/SDCCval.c (valDiv, valMod): fixed signdness
9316 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9317 signedness of modulo, left and right shift

9372 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
9374 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
9375 there, while the mantissa of a double is "only" 53 bits wide.
9377 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9776 * src/SDCCmain.c: linkOptions is changed to set *,
9777 added if/endif conditional macros to remove options help
9778 messages from optionsTable when a port is not configured, added
9779 support for the PIc16 port in the ports table, when executing
9780 the compiler with no port specified on command line, a default
9781 port is selected with the new macro DEFAULT_PORT which is
9782 defined in port.h, in setDefaultOptions() linkOptions is removed
9783 from initialization assignment, since now it is a set,
9784 parseCmdLine uses setParseWithComma for linkOptions, in
9785 linkEdit() linkOptions are accessed with new function indexSet()
9786 which returns the i'th item of a set variable. See SDCCset.c, in
9787 linkEdit() when calling buildCmdLine(), added linkOptions as
9788 last argument. Now users can pass arguments to gplink via the
9789 -Wl option, main() uses pic16glue() to glue up pic16 programs

9803 gpasm complaining and test the linkage with gplink, _linkCmd and
9804 _asmCmd changed to be more gplink and gpasm friendly
9805 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9806 produced an error when parsed, peep rule 12 is added to utilize
9807 movff, but it is commented out since the pCode does not support
9808 yet a command with 2 address arguments
9810 2003-05-18 <johan AT balder>
9812 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9839 2003-05-11 Borut Razem <borut.razem AT siol.net>
9841 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9842 the path of bin directory, so that PATH is the only env. variable, which has to be set

10834 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10835 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10836 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10837 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

10845 2003-01-06 <johan AT balder>
10847 * src/SDCCicode.c: fixed array add
10849 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10850 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10851 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10853 2003-01-04 <johan AT balder>

10857 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10858 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10860 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10861 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10870 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10871 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10873 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10875 * in /sdcc/as/mcs51/ changed these files in order to create an
10876 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10877 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10878 following files to include the previous two files: aslink.dsp,
10879 Makefile.aslink, Makefile.bcc, and Makefile.in.
10881 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10882 .adb instead of .cdb
10884 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10886 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10887 value from option --iram-size.
10889 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10891 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10894 2002-09-18 <wiml AT hhhh.org>
10896 * SDCClrange.h: exposed setFromRange() and setToRange()
10897 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10898 packRegsForAccUse() (bug 542397)
10899 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10900 multiple times and emitting the fetch operations more than once
10901 added aopGetUsesAcc() function to allow binary operators to
10902 fetch their operands in the correct order; made genMinus() emit
10903 compact code for X = LITERAL - Y
10905 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10906 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10907 sprintf() in line 1267.
10909 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10910 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10913 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10914 Changes to aslink (All the changes are marked with 'JCF'):
10916 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10919 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10920 area BSEG. Also moves, if possible, the DATA area down into the internal
10921 ram so more space is available.
10923 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10926 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10927 not bytes. Function summary() which creates a memory usage summary
10928 file with extension .mem. Reports of overlaping stack and small stack
10929 size. If the space for the stack is less than 16 bytes aslink trows a
10932 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10933 the 8051. Option 'y' for memory summary output file.
10935 Changes to sdcc (All the changes are marked with 'JCF'):
10937 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10939 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10940 overlaying area for it (uses RegBankUsed[4]).
10942 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10943 bank zero as used by default. By default aslink locates the stack
10944 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10945 the creation of the .mem file. Delegates the allocation of data area
10946 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10947 the begining of the stack area to aslink.
10949 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10950 glue() in SDCCglue.c creates an area for it.
10952 2002-09-03 Borut Razem <borut.razem AT siol.net>
10953 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10954 sdcc/src/pic/glue.c:
10955 introduced atexit() handler for teporay files removal in case of
10956 errors, assertions, ...
10958 2002-08-29 Borut Razem <borut.razem AT siol.net>
10959 * sdcc/support/cpp2/auto-host_vc_in.h:
10960 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10961 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10962 Maybe there is a similar problem with BORLANDC? It should be checked!
10964 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10965 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10966 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10967 was not executed, and the compiler (cl) launched a warning:
10968 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10970 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10971 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10973 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10974 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10976 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10977 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10978 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10979 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10980 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10981 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10982 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10983 - added Release configuration in VS projects
10984 - review of compiler an linker options
10985 - VC .exe files are generated in bin_vc directory, not to interfere
10986 with binaries generated from other projects (cygwin, mingw, bcc ...)
10988 * sdcc/src/yacc.dsp: added
10990 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10991 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10992 and insert the version number definitions from .version
10994 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10996 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10997 added - genarate auto-host.h using auto-host_vc_in.h as template
11000 removed from CVS, generated automatically
11002 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11003 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11005 2002-08-11 Borut Razem <borut.razem AT siol.net>
11006 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11008 2002-08-10 Borut Razem <borut.razem AT siol.net>
11009 * src/SDCCmain.c (main):
11010 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11011 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11012 The consequence was that some temporary files were not removed.
11015 unification of code in functions tempfilename() and tempfile():
11016 function tempnam() is defined in Visual Studio 6.0 and .NET
11018 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11020 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11021 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11022 - removed compiler command line option /WX: Treats all warnings as errors
11023 - update a list of source files, included into the project
11025 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11026 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11027 changed project type to Generic Project so that can be correcly converted to VS.NET project
11029 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11031 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11033 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11035 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11036 added return 0 statements after assert() to make compiler happy
11038 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11039 added newline in the def file to keep MSC compiler satisfied
11041 * sdcc/src/z80/gen.c:
11042 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11043 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11044 - solved MSC error in function aopDump()
11046 * sdcc_vc.h: define PREFIX as "\\sdcc"
11048 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11049 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11051 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11052 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11053 - Rewrote the register banking algorithm.
11054 - Added pCode live-range analysis to registers (for now, only non-used and
11055 singly-used registers optimized away)
11057 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11059 * 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.

11076 * device/lib/z80/printf.c (sprintf): Added.
11078 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11080 * src/z80/peeph.def: Added transpose redundent load rule.
11082 * src/z80/main.c: Added force callee saves for jaune.
11084 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11086 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11088 2002-03-28 Johan Knol <johan AT balder>
11090 * src/SDCCval.c: fixed bug #532436
11092 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11094 Added "char *Processor" field to the port structure.
11097 Added -p option. Allows port dependent processor to be specified.
11100 Initialized the new field char *Processor field to NULL in all ports
11103 Compiler generated registers for interrupt context saving
11104 were not getting allocated.
11106 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11109 Fixed left shift. Will promote the left side of a left shift
11110 if a) left shifting more than size of operand or b) when assigned
11111 to something size > size of left side
11113 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11115 tons of changes. Register allocation has been
11116 rewritten. Added customization for the various PICs. Flow
11117 analysis is restructured. ...
11119 * src/pic/device.h:
11122 * src/pic/device.c:
11123 Added. device.c is a PIC port hack to accomodate variations
11126 2002-03-13 Michael Hope <michaelh AT vroom>
11128 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11130 2002-03-04 johanknol <johanknol AT manik>
11132 * /src/SDCCval.c: fixed
11134 const unsigned char arr[][2] = { { 0, 1 } };

11221 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11223 * sdcc/src/SDCCloop.c:
11224 Previous fix was not good. basic blocks that have "break" or "return" are
11225 not really partof a loop , but live ranges used in these blocks should
11226 be live thru the entire loop, so set partOfLoop but don't add them to
11229 2002-02-21 <johan AT FRIJA>
11231 * src/SDCCcse.c: fixed bug #514308
11233 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11236 Fixed BUG #519583. If a conditional block ended in a return/break
11237 statement inside a loop, it was not being considered part of the loop.
11239 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11241 2002-02-10 Karl Bongers <karl AT turbobit.com>
11244 Fixed up SDCDB debugger somewhat. Updated debugger/README
11245 with lots of comments and notes.
11247 * device/examples/test2.c:
11248 Fix bug, "red" variable not being initialized(compiler complained).
11250 * device/examples/Makefile, examples/test3.c:
11251 Add Makefile in device/examples folder, compiles test3.c
11252 for use as a multiple module SDCDB test case.
11254 * sim/ucsim/cmd.src/cmdset.cc:
11255 Took out debug printfs in ucsim "next" command.
