1006 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1007 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1009 One basic decision: e.g. src/clean.mk includes further files. In order
1010 to make this work there are two solutions:
1011 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1012 run configure on them. This way they can use
1013 'include $(srcdir)/port-clean.mk'
1014 - always include clean.mk by the Makefile at the same level. To avoid
1015 that `make clean` tries to include and build Makefile.dep the
1016 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1017 implemented, because now even `make uninstall` doesn't create
1018 Makefile.in. clean.mk could be eliminated by pasting it in
1021 * debugger/mcs51/Makefile.in: build own objects from library sources
1022 (SLIB, SDCC) in current directory
1024 * configure, configure.in: renamed --disable-device-lib-build in
1025 --disable-device-lib; added --enable-doc, the required tools are
1026 searched by configure; added result message; the toolchain for the
1027 belonging ports are now only built, if the port is enabled.
1029 * support/regression/*: all output is written in directory gen, because
1030 the fwk and ports directories don't livet in the build tree using vpath
1032 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1033 --disable-device-lib, added --enable-doc, added section VPATH
1035 * sim/ucsim/configure.in,
1036 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1037 z80 are enabled by default
1039 2006-04-24 Raphael Neider <rneider AT web.de>
1041 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1042 to config word, "pic14_"-prefixed some extern functions
1043 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1044 config word has been found
1045 * src/pic/device.h: added prototypes
1046 * src/pic/pcode.c: added "pic14_"-prefix where needed

1063 fixes #1469504 and #1474602,
1064 (pCodeRegOptimizeRegUsage): fixed typo in comment

1310 implemented patch 1120823 Thanks to Willy De la Court (normal
1311 interrupts need an interrupt number now if they are made critical),
1312 and enabled nesting of critical functions though not for gbz80
1313 (genCritical, genEndCritical): added functions
1314 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1315 * src/z80/mappings.i: added "ei" to all mappings

1324 2006-03-16 Raphael Neider <rneider AT web.de>
1326 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1327 the left operand is shorter than the result (c* = lit-c* + int),
1329 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1332 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1334 * src/.version: increased version number to 2.5.5
1335 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1336 linking is done manually in pic16 port's _linkEdit,
1337 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1338 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1339 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1340 allocate asmop as AOP_ACC,
1341 (aopForRemat): added parameter 'bool result' in function declaration,
1342 (pic16_aopGet): return AOP_ACC when accessing WREG,
1343 (pic16_popGetTempReg): minor modification,
1344 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1345 'pic16_allocWithIdx',
1346 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1347 calling function in absolute addresses,
1348 (genAssign): take into account AOP_ACC asmop,
1349 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1350 * src/pic16/pcoderegs.c: some debug functions and lines added,

1352 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1354 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1355 call to allocReg, not by manually allocating a new one,
1356 (pic16_assignRegisters): now before going through the register

1382 (aopForSym, aopOp): increment asmop.allocated if reused,
1383 (freeAsmop): decrement asmop.allocated and check for zero instead of
1385 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1386 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1408 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1410 2006-03-06 Borut Razem <borut.razem AT siol.net>
1412 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1413 made the linker quiet
1415 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1417 * src/pic16/gen.c (genPcall): fixed bug #1443644
1418 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1419 which dumps before the function entry point a data byte which represents
1420 the number of the local variables used by the specified function, added
1421 'xinst' for initial support for Extended Instruction Support,
1422 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1423 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1424 port->fun_prefix anymore (may change later),

1426 _main (this should take care the --main-return command line option in
1428 (genOr): removed some legacy pic-port instructions,
1429 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1430 performing operations with SFR's causes data to be written more than

1437 --extended or -y for Extended Instruction Support,
1438 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1439 (deassignLRs): *** perhaps the most important change, old 'for' code
1440 (commented out for reference), didn't account for some registers which
1441 were left marked 'not free' after a pointer operation. The change
1442 reduces register usage a lot in some cases

3717 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3718 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3719 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3720 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3721 always available in leading double underscore form. The C99 support is

3800 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3802 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3804 * device/lib/printf_large.c: removed inline assembly for portability and
3805 readability. Use printf_fast if speed or size are more important.
3806 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3807 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3809 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3811 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3812 prevent compiler warning
3814 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3816 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3817 moved to level 0 and declared as static. Also they are explicit
3818 placed in access bank. This was necessery because some times they
3819 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3820 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3821 optimizations. Currently only compare to unsigned char is implemented,
3822 * src/pic16/gen.c: added fReturnIdx array,
3823 * (struct resolvedIfx) is moved to gen.h and made public,
3824 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3825 * (aopForSym): added an optimization to directly store in stack of
3826 the operand of a SEND iCode,
3827 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3828 but as registers instead (AOP_REG) using the fReturnIdx array,
3829 * (pic16_freeAsmop): remove the freed register from the
3830 _G.sregsAlloc field,
3831 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3832 a compare of 'WREG',
3833 * (pic16_popGetTempRegCond): changed function prototype, now
3834 function takes also a bitVector argument v which holds the current
3835 set of registers that are allocated for stack access by aopForSym,
3836 registers allocated in aopForSym for accessing stack symbols are not
3837 any more part of the functions usedRegs field,
3838 * (genCall): some times aopOp is called for a stack variable to be
3839 send, aopForSym might perform the push, if this is true make sure
3840 that genCall doesn't push the variable twice by testing _G.resDirect,
3841 * (genFunction): changed testing for unspecified interrupt number
3842 from 256 to INTNO_UNSPEC,
3843 * modified selection scheme of frame pointer generation. Previously
3844 if function did use local registers a frame pointer was generated,
3845 now a frame pointer is generated only if function has arguments
3846 (that need PLUSW2 register access), or has stack arguments, or the
3847 compiler is not instructed to omit the frame pointer,
3848 * (genEndFunction): before restoring local registers that were saved
3849 in the function preamble, also restore the registers that *might*
3850 have been allocated for stack access,
3851 * (genRet): removed some old comments,
3852 * (genCmp, the active (RN's) version): added a call to the
3853 pic16_genCmp_special function to perform the compare with a more
3854 robust and optimized way,
3855 * (genInline): a feature has been added in inline code generation,
3856 which allows a wildcard variable substitution when writing inline
3857 assembly. Code is incomplete and experimental therefore undocumented,
3858 * (genCast): changed order of aopOp for result and right to allow
3859 aopForSym to directly load the result if possible,
3860 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3861 perform an optimized compare on some selected special occasions,
3862 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3863 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3864 generate an IVT any more,
3865 * src/pic16/main.c (pic16_optionsTable): added command line option
3867 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3868 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3870 * src/pic16/NOTES: Raphael Neider added in list of active developers
3871 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3872 jumptable_end to prevent bug #,
3873 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3874 inCond and outCond fields,
3875 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3876 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3877 turn off register spilling,
3878 * (packRegsForOneUse): synced with other ports' versions although it
3879 is not used currently,
3880 * (pic16_packRegisters): added an optimization while reading
3881 structure bitfields, some registers may be saved (malloc code is
3882 decreased by 80 bytes)
3884 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3886 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3887 left is a bitfield, if yes, then don't optimize assignment. Perhaps

4528 Adding support for replacing ljmps with sjmps in jumptables
4529 generated for switch statements. For now you need to set the
4530 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4531 Now 4 algorithms for mcs51 jumptable generation are used:
4532 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4533 addresses loaded pc-relative for up to 112 cases and stack-pushing
4534 target addresses loaded with offset from dptr for up to 256 cases.

4564 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4566 * added libc directory. The current version of LibC contains string
4567 functions, ctype functions and macros and some functions of the
4568 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4569 be extensively tested in the future. Standard disclaimer here.
4570 Library is not automatically build yet. But one can build it by
4571 invoking 'make' inside the libc directory.

4582 * (pic16_storeForReturn): optimized return of 0,
4583 * (genCmp): experimental code for new genCmp which uses PIC18's
4584 special compare&skip instructions. Initial tests fail some times
4585 with variables grater than 1 byte in size, so new code is disabled,
4586 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4588 * (genCast): began a fix to optimize the casting of a bit to another
4589 bit, now assigning a bitfield to another bitfield will fail, sorry,

4598 and 1 for banking instruction,
4599 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4600 caused stop processing pCodes after a inline assembly block,
4601 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4603 registers when it shouldn't,
4604 * src/pic16/ralloc.c (allocReg): add preliminary support for
4605 supporting a limited set of temporary registers,
4607 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7615 loaded with the linker search paths (-L arguments) and the libraries
7616 to be linked with the current source (-l arguments). Changes
7617 currently will affect only the pic16 port.
7618 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7619 include path the port specific paths and port specific libraries,
7620 * gplink command now contains the $3 argument,

7638 Documenting changes from previous commits.
7639 * configure.in (version 1.56),
7640 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7641 when generating output files to configure the pic16 library,
7642 but now I've commented it out, since gputils aren't installed in the
7643 SF compile farm, so library won't compile
7645 * device/lib/Makefile.in (version 1.56): initially I've added in
7646 target 'all' the prerequestive 'model-pic16' so it compiled the
7647 pic16 library, but now I've commented it out for the same reasons
7649 * added targets 'model-pic16' and 'objects-pic16' to compile the
7651 * added target 'port-specific-objects-pic16' to handle the
7652 generated libraries and copy them into the build/ directory
7653 * added target 'clean-intermediate-pic16' to clean intermediate
7654 files into pic16 directory
7655 * in target 'installdirs' added line to create directory pic16 in

7899 * support/valdiag/tests/overflow.c: added
7900 * src/SDCCast.c (decorateType),
7901 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7902 LEFT_OP (left shift)
7904 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7906 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7907 (default behaviour).
7909 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7911 A python script to validate compiler diagnostic messages. It can be
7912 used to verify that sdcc complains about bad c source code and
7913 gives a good location of the error.
7914 * support/valdiag/Makefile,
7915 * support/valdiag/valdiag.py,
7916 * support/valdiag/tests/*
7918 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7920 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7921 * src/SDCCsymt.c (newEnumType),
7923 * support/Util/SDCCerr.c,
7924 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7926 * support/regression/tests/enum.c: added test for enum values that
7927 require at least 2 bytes of storage.
7929 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7931 * src/common.h: added ifndef/define/endif macros
7932 around the header file.
7933 Bug reported from Jesus Calvino-Fraga
7935 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7937 * sdcc.spec: updated
7938 * device/include/Makefile.in: don't install CVS directories
7939 * device/lib/Makefile.in: added removal of CVS directories after install
7940 * doc/Makefile: fixed install, added local_icons
7941 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7942 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7943 * src/ds390/gen.c (genRightShift): fixed bug #870788
7944 * src/SDCCast.c (decorateType): fixed bug #870781
7946 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7948 PIC16 port related changes:
7949 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7950 added variable stackPos,
7952 * gen.c: genCall, assignResultValue: added support for
7953 pushing/retrieving function parameters to/from stack,
7954 genFunction,genEndFunction: setup stack frame for the
7956 genAddrOf: will be changed according to bug 863624
7958 * added files genutils.c and genutils.h which contain gen*
7959 debugged and optimised functions extracted from gen.c
7961 * glue.c: added variable 'externs' which holds extern symbols,
7962 pic16emitRegularMap: is modified to properly handle relocatable
7963 symbols under the new scheme,
7964 pic16createInterruptVect: is modified
7965 pic16printPublics: is modified to emit 'global' assembler directives,
7966 added pic16_printExterns to print extern symbols,
7967 pic16glue: initializes stack/frame pointer in the beginning of
7968 the assembly output. Temporary hack, will be corrected later,
7969 because gplink yet does not support stack and SDCC does not
7970 yet support a type of crt0.o object to create the final binary.
7972 * Removed many lines that contain 8051 legacy code.
7973 * The code is finally placed under a 'code' directive.
7974 * Added port specific options.
7976 * _process_pragma: simplified since now we do not need *special*
7977 include file to define SFR registers. But a separate header
7978 will be needed. This will be developed later.
7979 * _pic16_parseOptions: added, parses port specific options:
7980 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7981 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7982 --preplace-udata-with=
7984 * _pic16_setDefaultOptions: modified to initialize section names,
7985 but hack is temporarly out of order since it needs improvement.
7986 * _pic16_genAssemblerPreamble: configuration words are emitted by
7987 their address instead of their name. This part is incomplete and
7988 supports only the 18Fxx2 devices. Other devices will emit an error
7989 during assembly since they do not contain the same set of config
7991 * _pic16_genIVT: is modified,
7993 * pcode.c: added definitions for some hardware registers that are needed
7995 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7996 All PCI entries are updated. Now LFSR is supported.
7997 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7998 * added pic16_newpCodeOpLit2 to support instructions with
7999 two literal arguments
8000 * pic16_pCode2str: corrected code that emits assembler instructions
8001 with two literal operands and those that have an access bit modifier
8002 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8003 this fixes a bug which caused some labels to be lost, when an
8004 assembler directive was added, i.e. banksel,
8005 * pic16_FixRegisterBanking: improved logic that causes the insertion
8007 * InlineFunction: functions that are called once, are not any more
8008 inlined. This can be a port option in the future,
8010 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8012 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8013 hold the corresponding uninitialized symbols,
8014 * pic16_allocProcessorRegister: registers have explicit marked the
8016 * pic16_allocInternalRegister: registers are explicit marked as
8018 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8019 processing list, so bit registers were lost,
8022 * ralloc.h: added field 'accessBank' and original symbol operand
8023 in register definition,
8024 * removed the field isMapped from register definition,
8026 ** Several functions have been removed from various sources:
8027 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8028 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8029 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8030 pic16_assignRelocatableRegisters
8032 ** others have been introduced:
8033 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8034 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8036 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8038 * support/scripts/inc2h.pl: changed definition of BIT_AT
8039 to emit 'sbit at' instead of 'bit at'. This was a request.
8041 PIC16 port related preliminary changes:
8042 * gen.c: prefixed function popRegFromString with
8043 pic16_ and all references to it corrected
8044 * pcode.c: all pic16_pc_* hardware registers prefixed
8045 with underscore (_),
8046 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8047 * ralloc.c: newReg(): when register is REG_SFR then
8048 set address to rIdx,
8049 pic16_allocProcessorRegister(): marks register wasUsed=0
8050 pic16_writeUsedRegs(): added a call to assign processor
8051 registers via pic16_assignFixedRegisters
8053 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8055 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8056 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8057 variables in unused register banks. Also the SSEG is placed
8058 wherever there is enough space for it, and IDATA can be anywhere
8059 in internal RAM. For now compile using -Wl-Y[stack_size].
8060 The mem file is different for this option as well, since it
8061 makes no sense of talking about DSEG lenght.
8063 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8065 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8066 in certain cases, e.g. when ROM assignment, patch provided
8067 from Albert den Haan.
8069 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8212 * src/mcs51/peephole.def,
8213 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8225 multiply defined with mismatching "at" address.
8227 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8229 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8308 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8310 * src/SDCCast.c (decorateType): disabled a transformation I added in
8311 revision 1.188 (access to fields of a structure at an absolute address);
8312 it breaks with bitfields, extern declarations, and gcse analysis.
8313 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8314 could be assigned through a pointer, so don't complain.
8315 * src/SDCCast.c (astErrors),
8317 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8897 genCodePointerGet, genGenPointerGet, genFarPointerSet,
8898 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
8899 (ralloc doesn't intentionally do this now, but perhaps later)
8900 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
8901 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

8952 * src/SDCCsymt.c (sclsFromPtr),
8954 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8955 support for standard C idiom of memory mapped variables; for
8956 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8957 to xdata int at 0x1234 tempvar = 1.
8958 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8959 provided by Akiya ISHIDA

8973 * src/z80/gen.c (genXor): Fixed bug #805445
8975 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8977 Fixed bug #621531 (const & volatile confusion in the type chain).
8978 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8979 refer to the const or volatile state of the pointer itself.

9044 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9045 pcoderegs.h, ralloc.c, ralloc.h
9046 * main.c: added top header and GPL license notice
9047 * pcode.c: fixed the if-conditional warning
9049 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>

9070 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9071 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9072 fetching of the pointer
9073 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9074 copied from genNearPointerSet()
9075 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9076 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9077 If they pop r0/r1 they must be called in the opposite order than aopOp().
9078 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9079 (resp. --stack-auto), prepared for --xstack

9090 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9092 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9093 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9094 type for bits was changed. It resulted in bit variables becoming
9095 global, which is not permitted in PIC 14 assembly output.
9097 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9099 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9101 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9103 Z80 and MCS51 linkers complaint if a public symbol is defined
9104 in more than one library module:

9112 A few small changes that speed up the peephole optimizer.
9116 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9118 Try to make the peephole optimizer smarter by maintaining
9119 an association between the assembly source code and the
9120 iCodes that originated them. Put this information to use
9121 with a new peephole rule condition "notVolatile" so that
9122 the rules can be aggressive yet still safe.
9127 * src/mcs51/peeph.def
9129 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9133 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9134 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9135 if the left or right operand symbols have the accuse flag set.
9137 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9139 Changed the type of the result of the ! (NOT) operator to char;
9140 previously it returned the same type as the source. This allows
9141 us to eliminate all the genFloatNot functions (all of its target
9142 implementations were very buggy) since !float can use the same
9145 * src/SDCCicode.c (ast2iCode): ! returns char

9147 * src/ds390/gen.c (genNot, genNotFloat),
9148 * src/z80/gen.c (genNot, genNotFloat),
9149 * src/pic/gen.c (genNot, genNotFloat),

9154 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9155 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9156 during interrupts. Ensure WSAVE is located at a shared bank address.
9157 2. Fixed page selection in some places
9158 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9159 the registers name strings.
9160 4. Fixed "signed / unsigned compare" compiler warnings.
9161 5. The PIC port manages its own allocation of the general purpose
9162 registers, but makes no attempt to reuse them. As a result when
9163 compiling it soon runs out of general purpose registers. Some
9164 additional code was added to the files pcode.c and device.c to walk
9165 through the function call tree and rename the registers so that they
9175 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9176 genPlus() & genMinus() when the result is the same as left or right
9178 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9182 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9184 Made bitfield a distinct type from bit so that bitfields
9185 convert as per ANSI C and bits retain their traditional
9186 boolean style behaviour. Implemented bitfield support in
9194 * src/ds390/gen.c: bit v bitfield split
9195 * src/z80/gen.c: New support for bitfields
9196 * support/regression/tests/bitfields.c: reenabled z80,
9199 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9201 Rules 246.x, 247.x relate to bitfields, the others speed up
9202 access to xdata mapped I/O devices.
9204 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9206 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9208 Cleaned up genPackBits and genUnpackBits and added two helper
9209 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9210 for literal assignments in genPackBits (thanks to Frieder for
9216 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9218 Fixed bug #748310 (pointer to function type mishandled when the
9219 function name is omitted). Also fixed a SIGSEGV when a function
9220 attribute (reentrant, etc) is used on a non-function or on a
9221 function but misplaced before the parameter list.
9223 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9225 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9226 * support/Util/SDCCerr.h,
9227 * support/Util/SDCCerr.c: Added func attr misuse error msg
9229 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9231 Fixed bug #787649 by anonymous
9232 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9248 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9250 Made the constant following the "interrupt" keyword optional. If
9251 omitted, the function will not automatically be given an entry
9252 in the interrupt vector table (similar to #pragma NOIV, but
9253 less syntacticly kludgy). The interrupt number is also now
9254 range checked. Also fixed a bug in the high order bit example

9262 * support/Util/SDCCerr.h
9265 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9267 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9268 * src/SDCCicode.c (operandOperation): rewritten some ops
9269 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9270 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9272 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9273 be re-activated by defining REDUCE_LITERALS)
9274 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9275 unsigned, but are signed by default
9276 * src/SDCCval.c (constVal): rearranged
9277 * src/SDCCval.c (valMod): preliminary fix
9278 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9320 constants are unsigned; added recognition of "u" flag for unsigned
9321 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9322 * src/SDCCval.c (valDiv, valMod): fixed signdness
9323 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9324 signedness of modulo, left and right shift

9784 added if/endif conditional macros to remove options help
9785 messages from optionsTable when a port is not configured, added
9786 support for the PIc16 port in the ports table, when executing
9787 the compiler with no port specified on command line, a default
9788 port is selected with the new macro DEFAULT_PORT which is
9789 defined in port.h, in setDefaultOptions() linkOptions is removed
9790 from initialization assignment, since now it is a set,
9791 parseCmdLine uses setParseWithComma for linkOptions, in
9792 linkEdit() linkOptions are accessed with new function indexSet()
9793 which returns the i'th item of a set variable. See SDCCset.c, in
9794 linkEdit() when calling buildCmdLine(), added linkOptions as
9795 last argument. Now users can pass arguments to gplink via the
9796 -Wl option, main() uses pic16glue() to glue up pic16 programs

9810 gpasm complaining and test the linkage with gplink, _linkCmd and
9811 _asmCmd changed to be more gplink and gpasm friendly
9812 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9813 produced an error when parsed, peep rule 12 is added to utilize
9814 movff, but it is commented out since the pCode does not support
9815 yet a command with 2 address arguments
9817 2003-05-18 <johan AT balder>
9819 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9846 2003-05-11 Borut Razem <borut.razem AT siol.net>
9848 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10841 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10842 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10843 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

10854 * src/SDCCicode.c: fixed array add
10856 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10857 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10858 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10860 2003-01-04 <johan AT balder>

10864 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10865 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10867 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10868 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10871 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10872 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10874 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10875 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10877 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10878 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10880 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10882 * in /sdcc/as/mcs51/ changed these files in order to create an
10883 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10884 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10885 following files to include the previous two files: aslink.dsp,
10886 Makefile.aslink, Makefile.bcc, and Makefile.in.
10888 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10889 .adb instead of .cdb
10891 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10893 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10894 value from option --iram-size.
10896 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10898 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10901 2002-09-18 <wiml AT hhhh.org>
10903 * SDCClrange.h: exposed setFromRange() and setToRange()
10904 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10905 packRegsForAccUse() (bug 542397)
10906 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10907 multiple times and emitting the fetch operations more than once
10908 added aopGetUsesAcc() function to allow binary operators to
10909 fetch their operands in the correct order; made genMinus() emit
10910 compact code for X = LITERAL - Y
10912 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10913 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10914 sprintf() in line 1267.
10916 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10917 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10920 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10921 Changes to aslink (All the changes are marked with 'JCF'):
10923 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10926 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10927 area BSEG. Also moves, if possible, the DATA area down into the internal
10928 ram so more space is available.
10930 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10933 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10934 not bytes. Function summary() which creates a memory usage summary
10935 file with extension .mem. Reports of overlaping stack and small stack
10936 size. If the space for the stack is less than 16 bytes aslink trows a
10939 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10940 the 8051. Option 'y' for memory summary output file.
10942 Changes to sdcc (All the changes are marked with 'JCF'):
10944 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10946 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10947 overlaying area for it (uses RegBankUsed[4]).
10949 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10950 bank zero as used by default. By default aslink locates the stack
10951 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10952 the creation of the .mem file. Delegates the allocation of data area
10953 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10954 the begining of the stack area to aslink.
10956 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10957 glue() in SDCCglue.c creates an area for it.
10959 2002-09-03 Borut Razem <borut.razem AT siol.net>
10960 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10961 sdcc/src/pic/glue.c:
10962 introduced atexit() handler for teporay files removal in case of
10963 errors, assertions, ...
10965 2002-08-29 Borut Razem <borut.razem AT siol.net>
10966 * sdcc/support/cpp2/auto-host_vc_in.h:
10967 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10968 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10969 Maybe there is a similar problem with BORLANDC? It should be checked!
10971 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10972 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10973 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10974 was not executed, and the compiler (cl) launched a warning:
10975 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10977 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10978 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10980 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10981 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10983 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10984 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10985 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10986 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10987 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10988 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10989 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10990 - added Release configuration in VS projects
10991 - review of compiler an linker options
10992 - VC .exe files are generated in bin_vc directory, not to interfere
10993 with binaries generated from other projects (cygwin, mingw, bcc ...)
10995 * sdcc/src/yacc.dsp: added
10997 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10998 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10999 and insert the version number definitions from .version
11001 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11003 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11004 added - genarate auto-host.h using auto-host_vc_in.h as template
11007 removed from CVS, generated automatically
11009 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11010 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11012 2002-08-11 Borut Razem <borut.razem AT siol.net>
11013 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11015 2002-08-10 Borut Razem <borut.razem AT siol.net>
11016 * src/SDCCmain.c (main):
11017 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11018 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11019 The consequence was that some temporary files were not removed.
11022 unification of code in functions tempfilename() and tempfile():
11023 function tempnam() is defined in Visual Studio 6.0 and .NET
11025 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11027 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11028 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11029 - removed compiler command line option /WX: Treats all warnings as errors
11030 - update a list of source files, included into the project
11032 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11033 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11034 changed project type to Generic Project so that can be correcly converted to VS.NET project
11036 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11038 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11040 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11042 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11043 added return 0 statements after assert() to make compiler happy
11045 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11046 added newline in the def file to keep MSC compiler satisfied
11048 * sdcc/src/z80/gen.c:
11049 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11050 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11051 - solved MSC error in function aopDump()
11053 * sdcc_vc.h: define PREFIX as "\\sdcc"
11055 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11056 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11058 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11059 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11060 - Rewrote the register banking algorithm.
11061 - Added pCode live-range analysis to registers (for now, only non-used and
11062 singly-used registers optimized away)
11064 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11066 * 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.
11068 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11081 2002-04-15 Michael Hope <michaelh AT vroom>
11083 * device/lib/z80/printf.c (sprintf): Added.
11085 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11087 * src/z80/peeph.def: Added transpose redundent load rule.
11089 * src/z80/main.c: Added force callee saves for jaune.
11091 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11093 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11095 2002-03-28 Johan Knol <johan AT balder>
11097 * src/SDCCval.c: fixed bug #532436
11099 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11101 Added "char *Processor" field to the port structure.
11104 Added -p option. Allows port dependent processor to be specified.
11107 Initialized the new field char *Processor field to NULL in all ports
11110 Compiler generated registers for interrupt context saving
11111 were not getting allocated.
11113 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11116 Fixed left shift. Will promote the left side of a left shift
11117 if a) left shifting more than size of operand or b) when assigned
11118 to something size > size of left side
11120 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11122 tons of changes. Register allocation has been
11123 rewritten. Added customization for the various PICs. Flow
11124 analysis is restructured. ...
11126 * src/pic/device.h:
11129 * src/pic/device.c:
11130 Added. device.c is a PIC port hack to accomodate variations
11133 2002-03-13 Michael Hope <michaelh AT vroom>
11135 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11137 2002-03-04 johanknol <johanknol AT manik>
11139 * /src/SDCCval.c: fixed
11141 const unsigned char arr[][2] = { { 0, 1 } };
11142 t18.c:1: error: Initializer element is not constant

11228 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11230 * sdcc/src/SDCCloop.c:
11231 Previous fix was not good. basic blocks that have "break" or "return" are
11232 not really partof a loop , but live ranges used in these blocks should
11233 be live thru the entire loop, so set partOfLoop but don't add them to
11236 2002-02-21 <johan AT FRIJA>
11238 * src/SDCCcse.c: fixed bug #514308
11240 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11243 Fixed BUG #519583. If a conditional block ended in a return/break
11244 statement inside a loop, it was not being considered part of the loop.
11246 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11248 2002-02-10 Karl Bongers <karl AT turbobit.com>
