1011 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1013 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1014 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1016 One basic decision: e.g. src/clean.mk includes further files. In order
1017 to make this work there are two solutions:
1018 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1019 run configure on them. This way they can use
1020 'include $(srcdir)/port-clean.mk'
1021 - always include clean.mk by the Makefile at the same level. To avoid
1022 that `make clean` tries to include and build Makefile.dep the
1023 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1024 implemented, because now even `make uninstall` doesn't create
1025 Makefile.in. clean.mk could be eliminated by pasting it in
1028 * debugger/mcs51/Makefile.in: build own objects from library sources
1029 (SLIB, SDCC) in current directory
1031 * configure, configure.in: renamed --disable-device-lib-build in
1032 --disable-device-lib; added --enable-doc, the required tools are
1033 searched by configure; added result message; the toolchain for the
1034 belonging ports are now only built, if the port is enabled.
1036 * support/regression/*: all output is written in directory gen, because
1037 the fwk and ports directories don't livet in the build tree using vpath
1039 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1040 --disable-device-lib, added --enable-doc, added section VPATH
1042 * sim/ucsim/configure.in,
1043 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1044 z80 are enabled by default
1046 2006-04-24 Raphael Neider <rneider AT web.de>
1048 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1049 to config word, "pic14_"-prefixed some extern functions
1050 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1051 config word has been found
1052 * src/pic/device.h: added prototypes
1053 * src/pic/pcode.c: added "pic14_"-prefix where needed
1054 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1056 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1359 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1361 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1362 call to allocReg, not by manually allocating a new one,

1364 allocating functions mark all registers as free. This eliminates some
1365 side effects resulting from peephole parser done earlier in the backbone
1367 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1417 2006-03-06 Borut Razem <borut.razem AT siol.net>
1419 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1420 made the linker quiet
1422 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1424 * src/pic16/gen.c (genPcall): fixed bug #1443644
1425 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1426 which dumps before the function entry point a data byte which represents
1427 the number of the local variables used by the specified function, added
1428 'xinst' for initial support for Extended Instruction Support,
1429 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1430 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1431 port->fun_prefix anymore (may change later),
1432 (genFunction, genEndFunction): do not store/restore local registers for
1433 _main (this should take care the --main-return command line option in
1435 (genOr): removed some legacy pic-port instructions,
1436 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1437 performing operations with SFR's causes data to be written more than
1438 once to each SFR. Perhaps SFRs should be handled in special cases...
1439 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

1445 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1446 (deassignLRs): *** perhaps the most important change, old 'for' code
1447 (commented out for reference), didn't account for some registers which
1448 were left marked 'not free' after a pointer operation. The change
1449 reduces register usage a lot in some cases

3807 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3809 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3811 * device/lib/printf_large.c: removed inline assembly for portability and
3812 readability. Use printf_fast if speed or size are more important.
3813 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3814 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3816 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3818 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3819 prevent compiler warning
3821 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3823 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3824 moved to level 0 and declared as static. Also they are explicit
3825 placed in access bank. This was necessery because some times they
3826 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3827 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3828 optimizations. Currently only compare to unsigned char is implemented,
3829 * src/pic16/gen.c: added fReturnIdx array,
3830 * (struct resolvedIfx) is moved to gen.h and made public,
3831 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3832 * (aopForSym): added an optimization to directly store in stack of
3833 the operand of a SEND iCode,
3834 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3835 but as registers instead (AOP_REG) using the fReturnIdx array,
3836 * (pic16_freeAsmop): remove the freed register from the
3837 _G.sregsAlloc field,
3838 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3839 a compare of 'WREG',
3840 * (pic16_popGetTempRegCond): changed function prototype, now
3841 function takes also a bitVector argument v which holds the current
3842 set of registers that are allocated for stack access by aopForSym,
3843 registers allocated in aopForSym for accessing stack symbols are not
3844 any more part of the functions usedRegs field,
3845 * (genCall): some times aopOp is called for a stack variable to be
3846 send, aopForSym might perform the push, if this is true make sure
3847 that genCall doesn't push the variable twice by testing _G.resDirect,
3848 * (genFunction): changed testing for unspecified interrupt number
3849 from 256 to INTNO_UNSPEC,
3850 * modified selection scheme of frame pointer generation. Previously
3851 if function did use local registers a frame pointer was generated,
3852 now a frame pointer is generated only if function has arguments
3853 (that need PLUSW2 register access), or has stack arguments, or the
3854 compiler is not instructed to omit the frame pointer,
3855 * (genEndFunction): before restoring local registers that were saved
3856 in the function preamble, also restore the registers that *might*
3857 have been allocated for stack access,
3858 * (genRet): removed some old comments,
3859 * (genCmp, the active (RN's) version): added a call to the
3860 pic16_genCmp_special function to perform the compare with a more
3861 robust and optimized way,
3862 * (genInline): a feature has been added in inline code generation,
3863 which allows a wildcard variable substitution when writing inline
3864 assembly. Code is incomplete and experimental therefore undocumented,
3865 * (genCast): changed order of aopOp for result and right to allow
3866 aopForSym to directly load the result if possible,
3867 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3868 perform an optimized compare on some selected special occasions,
3869 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3870 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3871 generate an IVT any more,
3872 * src/pic16/main.c (pic16_optionsTable): added command line option
3874 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3875 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3877 * src/pic16/NOTES: Raphael Neider added in list of active developers
3878 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3879 jumptable_end to prevent bug #,
3880 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3881 inCond and outCond fields,
3882 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3883 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3884 turn off register spilling,
3885 * (packRegsForOneUse): synced with other ports' versions although it
3886 is not used currently,
3887 * (pic16_packRegisters): added an optimization while reading

4535 Adding support for replacing ljmps with sjmps in jumptables
4536 generated for switch statements. For now you need to set the
4537 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4538 Now 4 algorithms for mcs51 jumptable generation are used:
4539 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4540 addresses loaded pc-relative for up to 112 cases and stack-pushing
4541 target addresses loaded with offset from dptr for up to 256 cases.

4571 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4573 * added libc directory. The current version of LibC contains string
4574 functions, ctype functions and macros and some functions of the
4575 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4576 be extensively tested in the future. Standard disclaimer here.
4577 Library is not automatically build yet. But one can build it by
4578 invoking 'make' inside the libc directory.

4589 * (pic16_storeForReturn): optimized return of 0,
4590 * (genCmp): experimental code for new genCmp which uses PIC18's
4591 special compare&skip instructions. Initial tests fail some times
4592 with variables grater than 1 byte in size, so new code is disabled,
4593 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4595 * (genCast): began a fix to optimize the casting of a bit to another
4596 bit, now assigning a bitfield to another bitfield will fail, sorry,

4605 and 1 for banking instruction,
4606 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4607 caused stop processing pCodes after a inline assembly block,
4608 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4610 registers when it shouldn't,
4611 * src/pic16/ralloc.c (allocReg): add preliminary support for
4612 supporting a limited set of temporary registers,
4614 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7622 loaded with the linker search paths (-L arguments) and the libraries
7623 to be linked with the current source (-l arguments). Changes
7624 currently will affect only the pic16 port.
7625 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7626 include path the port specific paths and port specific libraries,
7627 * gplink command now contains the $3 argument,
7628 * src/pic16/device.h,

7645 Documenting changes from previous commits.
7646 * configure.in (version 1.56),
7647 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7648 when generating output files to configure the pic16 library,
7649 but now I've commented it out, since gputils aren't installed in the
7650 SF compile farm, so library won't compile
7652 * device/lib/Makefile.in (version 1.56): initially I've added in
7653 target 'all' the prerequestive 'model-pic16' so it compiled the
7654 pic16 library, but now I've commented it out for the same reasons
7656 * added targets 'model-pic16' and 'objects-pic16' to compile the
7658 * added target 'port-specific-objects-pic16' to handle the
7659 generated libraries and copy them into the build/ directory
7660 * added target 'clean-intermediate-pic16' to clean intermediate
7661 files into pic16 directory
7662 * in target 'installdirs' added line to create directory pic16 in

7899 * as/mcs51/lkmain.c: Help about -Y option
7900 * as/mcs51/lkarea.c: Fixed gcc warnings
7902 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7904 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
7906 * support/valdiag/tests/overflow.c: added
7907 * src/SDCCast.c (decorateType),
7908 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7909 LEFT_OP (left shift)
7911 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7913 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7914 (default behaviour).
7916 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7918 A python script to validate compiler diagnostic messages. It can be
7919 used to verify that sdcc complains about bad c source code and
7920 gives a good location of the error.
7921 * support/valdiag/Makefile,
7922 * support/valdiag/valdiag.py,
7923 * support/valdiag/tests/*
7925 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7927 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7928 * src/SDCCsymt.c (newEnumType),
7930 * support/Util/SDCCerr.c,
7931 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7933 * support/regression/tests/enum.c: added test for enum values that
7934 require at least 2 bytes of storage.
7936 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7938 * src/common.h: added ifndef/define/endif macros
7939 around the header file.
7940 Bug reported from Jesus Calvino-Fraga
7942 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7944 * sdcc.spec: updated
7945 * device/include/Makefile.in: don't install CVS directories
7946 * device/lib/Makefile.in: added removal of CVS directories after install
7947 * doc/Makefile: fixed install, added local_icons
7948 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7949 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7950 * src/ds390/gen.c (genRightShift): fixed bug #870788
7951 * src/SDCCast.c (decorateType): fixed bug #870781
7953 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7955 PIC16 port related changes:
7956 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7957 added variable stackPos,
7959 * gen.c: genCall, assignResultValue: added support for
7960 pushing/retrieving function parameters to/from stack,
7961 genFunction,genEndFunction: setup stack frame for the
7963 genAddrOf: will be changed according to bug 863624
7965 * added files genutils.c and genutils.h which contain gen*
7966 debugged and optimised functions extracted from gen.c
7968 * glue.c: added variable 'externs' which holds extern symbols,
7969 pic16emitRegularMap: is modified to properly handle relocatable
7970 symbols under the new scheme,
7971 pic16createInterruptVect: is modified
7972 pic16printPublics: is modified to emit 'global' assembler directives,
7973 added pic16_printExterns to print extern symbols,
7974 pic16glue: initializes stack/frame pointer in the beginning of
7975 the assembly output. Temporary hack, will be corrected later,
7976 because gplink yet does not support stack and SDCC does not
7977 yet support a type of crt0.o object to create the final binary.
7979 * Removed many lines that contain 8051 legacy code.
7980 * The code is finally placed under a 'code' directive.
7981 * Added port specific options.
7983 * _process_pragma: simplified since now we do not need *special*
7984 include file to define SFR registers. But a separate header
7985 will be needed. This will be developed later.
7986 * _pic16_parseOptions: added, parses port specific options:
7987 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7988 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7989 --preplace-udata-with=
7991 * _pic16_setDefaultOptions: modified to initialize section names,
7992 but hack is temporarly out of order since it needs improvement.
7993 * _pic16_genAssemblerPreamble: configuration words are emitted by
7994 their address instead of their name. This part is incomplete and
7995 supports only the 18Fxx2 devices. Other devices will emit an error
7996 during assembly since they do not contain the same set of config
7998 * _pic16_genIVT: is modified,
8000 * pcode.c: added definitions for some hardware registers that are needed
8002 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8003 All PCI entries are updated. Now LFSR is supported.
8004 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8005 * added pic16_newpCodeOpLit2 to support instructions with
8006 two literal arguments
8007 * pic16_pCode2str: corrected code that emits assembler instructions
8008 with two literal operands and those that have an access bit modifier
8009 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8010 this fixes a bug which caused some labels to be lost, when an
8011 assembler directive was added, i.e. banksel,
8012 * pic16_FixRegisterBanking: improved logic that causes the insertion
8014 * InlineFunction: functions that are called once, are not any more
8015 inlined. This can be a port option in the future,
8017 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8019 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8020 hold the corresponding uninitialized symbols,
8021 * pic16_allocProcessorRegister: registers have explicit marked the
8023 * pic16_allocInternalRegister: registers are explicit marked as
8025 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8026 processing list, so bit registers were lost,
8029 * ralloc.h: added field 'accessBank' and original symbol operand
8030 in register definition,
8031 * removed the field isMapped from register definition,
8033 ** Several functions have been removed from various sources:
8034 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8035 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8036 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8037 pic16_assignRelocatableRegisters
8039 ** others have been introduced:
8040 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8041 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8043 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8045 * support/scripts/inc2h.pl: changed definition of BIT_AT
8046 to emit 'sbit at' instead of 'bit at'. This was a request.
8048 PIC16 port related preliminary changes:
8049 * gen.c: prefixed function popRegFromString with
8050 pic16_ and all references to it corrected
8051 * pcode.c: all pic16_pc_* hardware registers prefixed
8052 with underscore (_),
8053 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8054 * ralloc.c: newReg(): when register is REG_SFR then
8055 set address to rIdx,
8056 pic16_allocProcessorRegister(): marks register wasUsed=0
8057 pic16_writeUsedRegs(): added a call to assign processor
8058 registers via pic16_assignFixedRegisters
8060 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8062 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8063 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8064 variables in unused register banks. Also the SSEG is placed
8065 wherever there is enough space for it, and IDATA can be anywhere
8066 in internal RAM. For now compile using -Wl-Y[stack_size].
8067 The mem file is different for this option as well, since it
8068 makes no sense of talking about DSEG lenght.
8070 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8072 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8073 in certain cases, e.g. when ROM assignment, patch provided
8074 from Albert den Haan.
8076 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8219 * src/mcs51/peephole.def,
8220 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8232 multiply defined with mismatching "at" address.
8234 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8236 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8315 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8317 * src/SDCCast.c (decorateType): disabled a transformation I added in
8318 revision 1.188 (access to fields of a structure at an absolute address);
8319 it breaks with bitfields, extern declarations, and gcse analysis.
8320 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8321 could be assigned through a pointer, so don't complain.
8322 * src/SDCCast.c (astErrors),
8324 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8959 * src/SDCCsymt.c (sclsFromPtr),
8961 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8962 support for standard C idiom of memory mapped variables; for
8963 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8964 to xdata int at 0x1234 tempvar = 1.
8965 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8966 provided by Akiya ISHIDA

8982 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8984 Fixed bug #621531 (const & volatile confusion in the type chain).
8985 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8986 refer to the const or volatile state of the pointer itself.

9077 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9078 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9079 fetching of the pointer
9080 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9081 copied from genNearPointerSet()
9082 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9083 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9084 If they pop r0/r1 they must be called in the opposite order than aopOp().
9085 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9086 (resp. --stack-auto), prepared for --xstack

9097 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9099 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9100 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9101 type for bits was changed. It resulted in bit variables becoming
9102 global, which is not permitted in PIC 14 assembly output.
9104 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9106 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9108 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9110 Z80 and MCS51 linkers complaint if a public symbol is defined
9111 in more than one library module:

9117 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9119 A few small changes that speed up the peephole optimizer.
9123 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9125 Try to make the peephole optimizer smarter by maintaining
9126 an association between the assembly source code and the
9127 iCodes that originated them. Put this information to use
9128 with a new peephole rule condition "notVolatile" so that
9129 the rules can be aggressive yet still safe.
9134 * src/mcs51/peeph.def
9136 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9140 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9141 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9142 if the left or right operand symbols have the accuse flag set.
9144 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9146 Changed the type of the result of the ! (NOT) operator to char;
9147 previously it returned the same type as the source. This allows
9148 us to eliminate all the genFloatNot functions (all of its target
9149 implementations were very buggy) since !float can use the same
9152 * src/SDCCicode.c (ast2iCode): ! returns char
9153 * src/mcs51/gen.c (genNot, genNotFloat),
9154 * src/ds390/gen.c (genNot, genNotFloat),
9155 * src/z80/gen.c (genNot, genNotFloat),
9156 * src/pic/gen.c (genNot, genNotFloat),
9157 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9159 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9161 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9162 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9163 during interrupts. Ensure WSAVE is located at a shared bank address.
9164 2. Fixed page selection in some places
9165 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9166 the registers name strings.
9167 4. Fixed "signed / unsigned compare" compiler warnings.
9168 5. The PIC port manages its own allocation of the general purpose
9169 registers, but makes no attempt to reuse them. As a result when
9170 compiling it soon runs out of general purpose registers. Some
9171 additional code was added to the files pcode.c and device.c to walk
9172 through the function call tree and rename the registers so that they
9182 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9183 genPlus() & genMinus() when the result is the same as left or right
9185 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9189 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9191 Made bitfield a distinct type from bit so that bitfields
9192 convert as per ANSI C and bits retain their traditional
9193 boolean style behaviour. Implemented bitfield support in
9201 * src/ds390/gen.c: bit v bitfield split
9202 * src/z80/gen.c: New support for bitfields
9203 * support/regression/tests/bitfields.c: reenabled z80,
9206 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9208 Rules 246.x, 247.x relate to bitfields, the others speed up
9209 access to xdata mapped I/O devices.
9211 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9213 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9215 Cleaned up genPackBits and genUnpackBits and added two helper
9216 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9217 for literal assignments in genPackBits (thanks to Frieder for
9223 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9225 Fixed bug #748310 (pointer to function type mishandled when the
9226 function name is omitted). Also fixed a SIGSEGV when a function
9227 attribute (reentrant, etc) is used on a non-function or on a
9228 function but misplaced before the parameter list.
9230 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9232 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9233 * support/Util/SDCCerr.h,
9234 * support/Util/SDCCerr.c: Added func attr misuse error msg
9236 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9238 Fixed bug #787649 by anonymous
9239 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9255 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9257 Made the constant following the "interrupt" keyword optional. If
9258 omitted, the function will not automatically be given an entry
9259 in the interrupt vector table (similar to #pragma NOIV, but
9260 less syntacticly kludgy). The interrupt number is also now
9261 range checked. Also fixed a bug in the high order bit example
9268 * support/Util/SDCCerr.c
9269 * support/Util/SDCCerr.h
9272 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9274 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9275 * src/SDCCicode.c (operandOperation): rewritten some ops
9276 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9277 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9279 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9280 be re-activated by defining REDUCE_LITERALS)
9281 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9282 unsigned, but are signed by default
9283 * src/SDCCval.c (constVal): rearranged
9284 * src/SDCCval.c (valMod): preliminary fix
9285 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9327 constants are unsigned; added recognition of "u" flag for unsigned
9328 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9329 * src/SDCCval.c (valDiv, valMod): fixed signdness
9330 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9331 signedness of modulo, left and right shift

9382 Messed up 'configure', so revert to previous version:
9386 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
9388 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
9389 there, while the mantissa of a double is "only" 53 bits wide.
9391 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9792 messages from optionsTable when a port is not configured, added
9793 support for the PIc16 port in the ports table, when executing
9794 the compiler with no port specified on command line, a default
9795 port is selected with the new macro DEFAULT_PORT which is
9796 defined in port.h, in setDefaultOptions() linkOptions is removed
9797 from initialization assignment, since now it is a set,
9798 parseCmdLine uses setParseWithComma for linkOptions, in
9799 linkEdit() linkOptions are accessed with new function indexSet()
9800 which returns the i'th item of a set variable. See SDCCset.c, in
9801 linkEdit() when calling buildCmdLine(), added linkOptions as
9802 last argument. Now users can pass arguments to gplink via the
9803 -Wl option, main() uses pic16glue() to glue up pic16 programs

9817 gpasm complaining and test the linkage with gplink, _linkCmd and
9818 _asmCmd changed to be more gplink and gpasm friendly
9819 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9820 produced an error when parsed, peep rule 12 is added to utilize
9821 movff, but it is commented out since the pCode does not support
9822 yet a command with 2 address arguments
9824 2003-05-18 <johan AT balder>
9826 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10863 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10864 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10865 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10867 2003-01-04 <johan AT balder>

10881 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10882 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10884 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10885 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10887 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10889 * in /sdcc/as/mcs51/ changed these files in order to create an
10890 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10891 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10892 following files to include the previous two files: aslink.dsp,
10893 Makefile.aslink, Makefile.bcc, and Makefile.in.
10895 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10896 .adb instead of .cdb
10898 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10900 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10901 value from option --iram-size.
10903 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10905 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10908 2002-09-18 <wiml AT hhhh.org>
10910 * SDCClrange.h: exposed setFromRange() and setToRange()
10911 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10912 packRegsForAccUse() (bug 542397)
10913 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10914 multiple times and emitting the fetch operations more than once
10915 added aopGetUsesAcc() function to allow binary operators to
10916 fetch their operands in the correct order; made genMinus() emit
10917 compact code for X = LITERAL - Y
10919 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10920 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10921 sprintf() in line 1267.
10923 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10924 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10927 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10928 Changes to aslink (All the changes are marked with 'JCF'):
10930 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10933 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10934 area BSEG. Also moves, if possible, the DATA area down into the internal
10935 ram so more space is available.
10937 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10940 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10941 not bytes. Function summary() which creates a memory usage summary
10942 file with extension .mem. Reports of overlaping stack and small stack
10943 size. If the space for the stack is less than 16 bytes aslink trows a
10946 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10947 the 8051. Option 'y' for memory summary output file.
10949 Changes to sdcc (All the changes are marked with 'JCF'):
10951 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10953 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10954 overlaying area for it (uses RegBankUsed[4]).
10956 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10957 bank zero as used by default. By default aslink locates the stack
10958 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10959 the creation of the .mem file. Delegates the allocation of data area
10960 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10961 the begining of the stack area to aslink.
10963 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10964 glue() in SDCCglue.c creates an area for it.
10966 2002-09-03 Borut Razem <borut.razem AT siol.net>
10967 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10968 sdcc/src/pic/glue.c:
10969 introduced atexit() handler for teporay files removal in case of
10970 errors, assertions, ...
10972 2002-08-29 Borut Razem <borut.razem AT siol.net>
10973 * sdcc/support/cpp2/auto-host_vc_in.h:
10974 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10975 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10976 Maybe there is a similar problem with BORLANDC? It should be checked!
10978 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10979 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10980 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10981 was not executed, and the compiler (cl) launched a warning:
10982 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10984 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10985 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10987 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10988 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10990 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10991 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10992 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10993 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10994 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10995 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10996 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10997 - added Release configuration in VS projects
10998 - review of compiler an linker options
10999 - VC .exe files are generated in bin_vc directory, not to interfere
11000 with binaries generated from other projects (cygwin, mingw, bcc ...)
11002 * sdcc/src/yacc.dsp: added
11004 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11005 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11006 and insert the version number definitions from .version
11008 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11010 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11011 added - genarate auto-host.h using auto-host_vc_in.h as template
11014 removed from CVS, generated automatically
11016 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11017 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11019 2002-08-11 Borut Razem <borut.razem AT siol.net>
11020 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11022 2002-08-10 Borut Razem <borut.razem AT siol.net>
11023 * src/SDCCmain.c (main):
11024 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11025 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11026 The consequence was that some temporary files were not removed.
11029 unification of code in functions tempfilename() and tempfile():
11030 function tempnam() is defined in Visual Studio 6.0 and .NET
11032 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11034 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11035 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11036 - removed compiler command line option /WX: Treats all warnings as errors
11037 - update a list of source files, included into the project
11039 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11040 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11041 changed project type to Generic Project so that can be correcly converted to VS.NET project
11043 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11045 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11047 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11049 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11050 added return 0 statements after assert() to make compiler happy
11052 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11053 added newline in the def file to keep MSC compiler satisfied
11055 * sdcc/src/z80/gen.c:
11056 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11057 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11058 - solved MSC error in function aopDump()
11060 * sdcc_vc.h: define PREFIX as "\\sdcc"
11062 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11063 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11065 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11066 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11067 - Rewrote the register banking algorithm.
11068 - Added pCode live-range analysis to registers (for now, only non-used and
11069 singly-used registers optimized away)
11071 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11073 * 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.
11075 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11088 2002-04-15 Michael Hope <michaelh AT vroom>
11090 * device/lib/z80/printf.c (sprintf): Added.
11092 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11094 * src/z80/peeph.def: Added transpose redundent load rule.
11096 * src/z80/main.c: Added force callee saves for jaune.
11098 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11100 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11102 2002-03-28 Johan Knol <johan AT balder>
11104 * src/SDCCval.c: fixed bug #532436
11106 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11108 Added "char *Processor" field to the port structure.
11111 Added -p option. Allows port dependent processor to be specified.
11114 Initialized the new field char *Processor field to NULL in all ports
11117 Compiler generated registers for interrupt context saving
11118 were not getting allocated.
11120 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11123 Fixed left shift. Will promote the left side of a left shift
11124 if a) left shifting more than size of operand or b) when assigned
11125 to something size > size of left side
11127 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11129 tons of changes. Register allocation has been
11130 rewritten. Added customization for the various PICs. Flow
11131 analysis is restructured. ...
11133 * src/pic/device.h:
11136 * src/pic/device.c:
11137 Added. device.c is a PIC port hack to accomodate variations
11140 2002-03-13 Michael Hope <michaelh AT vroom>
11142 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11144 2002-03-04 johanknol <johanknol AT manik>
11146 * /src/SDCCval.c: fixed
11148 const unsigned char arr[][2] = { { 0, 1 } };
11149 t18.c:1: error: Initializer element is not constant

11235 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11237 * sdcc/src/SDCCloop.c:
11238 Previous fix was not good. basic blocks that have "break" or "return" are
11239 not really partof a loop , but live ranges used in these blocks should
11240 be live thru the entire loop, so set partOfLoop but don't add them to
11243 2002-02-21 <johan AT FRIJA>
11245 * src/SDCCcse.c: fixed bug #514308
11247 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11250 Fixed BUG #519583. If a conditional block ended in a return/break
11251 statement inside a loop, it was not being considered part of the loop.
11253 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11255 2002-02-10 Karl Bongers <karl AT turbobit.com>
