1005 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1007 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1008 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1010 One basic decision: e.g. src/clean.mk includes further files. In order
1011 to make this work there are two solutions:
1012 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1013 run configure on them. This way they can use
1014 'include $(srcdir)/port-clean.mk'
1015 - always include clean.mk by the Makefile at the same level. To avoid
1016 that `make clean` tries to include and build Makefile.dep the
1017 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1018 implemented, because now even `make uninstall` doesn't create
1019 Makefile.in. clean.mk could be eliminated by pasting it in
1022 * debugger/mcs51/Makefile.in: build own objects from library sources
1023 (SLIB, SDCC) in current directory
1025 * configure, configure.in: renamed --disable-device-lib-build in
1026 --disable-device-lib; added --enable-doc, the required tools are
1027 searched by configure; added result message; the toolchain for the
1028 belonging ports are now only built, if the port is enabled.
1030 * support/regression/*: all output is written in directory gen, because
1031 the fwk and ports directories don't livet in the build tree using vpath
1033 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1034 --disable-device-lib, added --enable-doc, added section VPATH
1036 * sim/ucsim/configure.in,
1037 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1038 z80 are enabled by default
1040 2006-04-24 Raphael Neider <rneider AT web.de>
1042 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1043 to config word, "pic14_"-prefixed some extern functions
1044 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1045 config word has been found
1046 * src/pic/device.h: added prototypes
1047 * src/pic/pcode.c: added "pic14_"-prefix where needed
1048 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1050 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1060 2006-04-24 Raphael Neider <rneider AT web.de>
1062 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1063 registers that have not been assigned proper liveranges,
1064 fixes #1469504 and #1474602,
1065 (pCodeRegOptimizeRegUsage): fixed typo in comment

1069 * device/examples/main8051.c: deleted - it was removed from CVS

1311 implemented patch 1120823 Thanks to Willy De la Court (normal
1312 interrupts need an interrupt number now if they are made critical),
1313 and enabled nesting of critical functions though not for gbz80
1314 (genCritical, genEndCritical): added functions
1315 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1316 * src/z80/mappings.i: added "ei" to all mappings

1325 2006-03-16 Raphael Neider <rneider AT web.de>
1327 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1328 the left operand is shorter than the result (c* = lit-c* + int),
1330 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1333 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1335 * src/.version: increased version number to 2.5.5
1336 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1337 linking is done manually in pic16 port's _linkEdit,
1338 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1339 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1340 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1341 allocate asmop as AOP_ACC,
1342 (aopForRemat): added parameter 'bool result' in function declaration,
1343 (pic16_aopGet): return AOP_ACC when accessing WREG,
1344 (pic16_popGetTempReg): minor modification,
1345 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1346 'pic16_allocWithIdx',
1347 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1348 calling function in absolute addresses,
1349 (genAssign): take into account AOP_ACC asmop,
1350 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1351 * src/pic16/pcoderegs.c: some debug functions and lines added,

1353 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1355 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1356 call to allocReg, not by manually allocating a new one,
1357 (pic16_assignRegisters): now before going through the register

1383 (aopForSym, aopOp): increment asmop.allocated if reused,
1384 (freeAsmop): decrement asmop.allocated and check for zero instead of
1386 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1387 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1409 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1411 2006-03-06 Borut Razem <borut.razem AT siol.net>
1413 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1414 made the linker quiet
1416 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1418 * src/pic16/gen.c (genPcall): fixed bug #1443644
1419 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1420 which dumps before the function entry point a data byte which represents
1421 the number of the local variables used by the specified function, added
1422 'xinst' for initial support for Extended Instruction Support,
1423 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1424 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1425 port->fun_prefix anymore (may change later),

1427 _main (this should take care the --main-return command line option in
1429 (genOr): removed some legacy pic-port instructions,
1430 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1431 performing operations with SFR's causes data to be written more than

1438 --extended or -y for Extended Instruction Support,
1439 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1440 (deassignLRs): *** perhaps the most important change, old 'for' code
1441 (commented out for reference), didn't account for some registers which
1442 were left marked 'not free' after a pointer operation. The change
1443 reduces register usage a lot in some cases

3718 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3719 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3720 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3721 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3722 always available in leading double underscore form. The C99 support is
3723 mostly missing, but it's a start.
3724 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3725 reserved identifier "__data".

3801 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3803 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3805 * device/lib/printf_large.c: removed inline assembly for portability and
3806 readability. Use printf_fast if speed or size are more important.
3807 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3808 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3810 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3812 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3813 prevent compiler warning
3815 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3817 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3818 moved to level 0 and declared as static. Also they are explicit
3819 placed in access bank. This was necessery because some times they
3820 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3821 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3822 optimizations. Currently only compare to unsigned char is implemented,
3823 * src/pic16/gen.c: added fReturnIdx array,
3824 * (struct resolvedIfx) is moved to gen.h and made public,
3825 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3826 * (aopForSym): added an optimization to directly store in stack of
3827 the operand of a SEND iCode,
3828 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3829 but as registers instead (AOP_REG) using the fReturnIdx array,
3830 * (pic16_freeAsmop): remove the freed register from the
3831 _G.sregsAlloc field,
3832 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3833 a compare of 'WREG',
3834 * (pic16_popGetTempRegCond): changed function prototype, now
3835 function takes also a bitVector argument v which holds the current
3836 set of registers that are allocated for stack access by aopForSym,
3837 registers allocated in aopForSym for accessing stack symbols are not
3838 any more part of the functions usedRegs field,
3839 * (genCall): some times aopOp is called for a stack variable to be
3840 send, aopForSym might perform the push, if this is true make sure
3841 that genCall doesn't push the variable twice by testing _G.resDirect,
3842 * (genFunction): changed testing for unspecified interrupt number
3843 from 256 to INTNO_UNSPEC,
3844 * modified selection scheme of frame pointer generation. Previously
3845 if function did use local registers a frame pointer was generated,
3846 now a frame pointer is generated only if function has arguments
3847 (that need PLUSW2 register access), or has stack arguments, or the
3848 compiler is not instructed to omit the frame pointer,
3849 * (genEndFunction): before restoring local registers that were saved
3850 in the function preamble, also restore the registers that *might*
3851 have been allocated for stack access,
3852 * (genRet): removed some old comments,
3853 * (genCmp, the active (RN's) version): added a call to the
3854 pic16_genCmp_special function to perform the compare with a more
3855 robust and optimized way,
3856 * (genInline): a feature has been added in inline code generation,
3857 which allows a wildcard variable substitution when writing inline
3858 assembly. Code is incomplete and experimental therefore undocumented,
3859 * (genCast): changed order of aopOp for result and right to allow
3860 aopForSym to directly load the result if possible,
3861 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3862 perform an optimized compare on some selected special occasions,
3863 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3864 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3865 generate an IVT any more,
3866 * src/pic16/main.c (pic16_optionsTable): added command line option
3868 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3869 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3871 * src/pic16/NOTES: Raphael Neider added in list of active developers
3872 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3873 jumptable_end to prevent bug #,
3874 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3875 inCond and outCond fields,
3876 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3877 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3878 turn off register spilling,
3879 * (packRegsForOneUse): synced with other ports' versions although it
3880 is not used currently,
3881 * (pic16_packRegisters): added an optimization while reading
3882 structure bitfields, some registers may be saved (malloc code is
3883 decreased by 80 bytes)
3885 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3887 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3888 left is a bitfield, if yes, then don't optimize assignment. Perhaps

4529 Adding support for replacing ljmps with sjmps in jumptables
4530 generated for switch statements. For now you need to set the
4531 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4532 Now 4 algorithms for mcs51 jumptable generation are used:
4533 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4534 addresses loaded pc-relative for up to 112 cases and stack-pushing
4535 target addresses loaded with offset from dptr for up to 256 cases.

4565 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4567 * added libc directory. The current version of LibC contains string
4568 functions, ctype functions and macros and some functions of the
4569 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4570 be extensively tested in the future. Standard disclaimer here.
4571 Library is not automatically build yet. But one can build it by
4572 invoking 'make' inside the libc directory.

4583 * (pic16_storeForReturn): optimized return of 0,
4584 * (genCmp): experimental code for new genCmp which uses PIC18's
4585 special compare&skip instructions. Initial tests fail some times
4586 with variables grater than 1 byte in size, so new code is disabled,
4587 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4589 * (genCast): began a fix to optimize the casting of a bit to another
4590 bit, now assigning a bitfield to another bitfield will fail, sorry,

4599 and 1 for banking instruction,
4600 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4601 caused stop processing pCodes after a inline assembly block,
4602 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4604 registers when it shouldn't,
4605 * src/pic16/ralloc.c (allocReg): add preliminary support for
4606 supporting a limited set of temporary registers,
4608 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7616 loaded with the linker search paths (-L arguments) and the libraries
7617 to be linked with the current source (-l arguments). Changes
7618 currently will affect only the pic16 port.
7619 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7620 include path the port specific paths and port specific libraries,
7621 * gplink command now contains the $3 argument,

7639 Documenting changes from previous commits.
7640 * configure.in (version 1.56),
7641 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7642 when generating output files to configure the pic16 library,
7643 but now I've commented it out, since gputils aren't installed in the
7644 SF compile farm, so library won't compile
7646 * device/lib/Makefile.in (version 1.56): initially I've added in
7647 target 'all' the prerequestive 'model-pic16' so it compiled the
7648 pic16 library, but now I've commented it out for the same reasons
7650 * added targets 'model-pic16' and 'objects-pic16' to compile the
7652 * added target 'port-specific-objects-pic16' to handle the
7653 generated libraries and copy them into the build/ directory
7654 * added target 'clean-intermediate-pic16' to clean intermediate
7655 files into pic16 directory
7656 * in target 'installdirs' added line to create directory pic16 in

7900 * support/valdiag/tests/overflow.c: added
7901 * src/SDCCast.c (decorateType),
7902 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7903 LEFT_OP (left shift)
7905 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7907 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7908 (default behaviour).
7910 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7912 A python script to validate compiler diagnostic messages. It can be
7913 used to verify that sdcc complains about bad c source code and
7914 gives a good location of the error.
7915 * support/valdiag/Makefile,
7916 * support/valdiag/valdiag.py,
7917 * support/valdiag/tests/*
7919 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7921 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7922 * src/SDCCsymt.c (newEnumType),
7924 * support/Util/SDCCerr.c,
7925 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7927 * support/regression/tests/enum.c: added test for enum values that
7928 require at least 2 bytes of storage.
7930 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7932 * src/common.h: added ifndef/define/endif macros
7933 around the header file.
7934 Bug reported from Jesus Calvino-Fraga
7936 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7938 * sdcc.spec: updated
7939 * device/include/Makefile.in: don't install CVS directories
7940 * device/lib/Makefile.in: added removal of CVS directories after install
7941 * doc/Makefile: fixed install, added local_icons
7942 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7943 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7944 * src/ds390/gen.c (genRightShift): fixed bug #870788
7945 * src/SDCCast.c (decorateType): fixed bug #870781
7947 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7949 PIC16 port related changes:
7950 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7951 added variable stackPos,
7953 * gen.c: genCall, assignResultValue: added support for
7954 pushing/retrieving function parameters to/from stack,
7955 genFunction,genEndFunction: setup stack frame for the
7957 genAddrOf: will be changed according to bug 863624
7959 * added files genutils.c and genutils.h which contain gen*
7960 debugged and optimised functions extracted from gen.c
7962 * glue.c: added variable 'externs' which holds extern symbols,
7963 pic16emitRegularMap: is modified to properly handle relocatable
7964 symbols under the new scheme,
7965 pic16createInterruptVect: is modified
7966 pic16printPublics: is modified to emit 'global' assembler directives,
7967 added pic16_printExterns to print extern symbols,
7968 pic16glue: initializes stack/frame pointer in the beginning of
7969 the assembly output. Temporary hack, will be corrected later,
7970 because gplink yet does not support stack and SDCC does not
7971 yet support a type of crt0.o object to create the final binary.
7973 * Removed many lines that contain 8051 legacy code.
7974 * The code is finally placed under a 'code' directive.
7975 * Added port specific options.
7977 * _process_pragma: simplified since now we do not need *special*
7978 include file to define SFR registers. But a separate header
7979 will be needed. This will be developed later.
7980 * _pic16_parseOptions: added, parses port specific options:
7981 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7982 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7983 --preplace-udata-with=
7985 * _pic16_setDefaultOptions: modified to initialize section names,
7986 but hack is temporarly out of order since it needs improvement.
7987 * _pic16_genAssemblerPreamble: configuration words are emitted by
7988 their address instead of their name. This part is incomplete and
7989 supports only the 18Fxx2 devices. Other devices will emit an error
7990 during assembly since they do not contain the same set of config
7992 * _pic16_genIVT: is modified,
7994 * pcode.c: added definitions for some hardware registers that are needed
7996 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7997 All PCI entries are updated. Now LFSR is supported.
7998 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7999 * added pic16_newpCodeOpLit2 to support instructions with
8000 two literal arguments
8001 * pic16_pCode2str: corrected code that emits assembler instructions
8002 with two literal operands and those that have an access bit modifier
8003 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8004 this fixes a bug which caused some labels to be lost, when an
8005 assembler directive was added, i.e. banksel,
8006 * pic16_FixRegisterBanking: improved logic that causes the insertion
8008 * InlineFunction: functions that are called once, are not any more
8009 inlined. This can be a port option in the future,
8011 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8013 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8014 hold the corresponding uninitialized symbols,
8015 * pic16_allocProcessorRegister: registers have explicit marked the
8017 * pic16_allocInternalRegister: registers are explicit marked as
8019 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8020 processing list, so bit registers were lost,
8023 * ralloc.h: added field 'accessBank' and original symbol operand
8024 in register definition,
8025 * removed the field isMapped from register definition,
8027 ** Several functions have been removed from various sources:
8028 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8029 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8030 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8031 pic16_assignRelocatableRegisters
8033 ** others have been introduced:
8034 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8035 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8037 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8039 * support/scripts/inc2h.pl: changed definition of BIT_AT
8040 to emit 'sbit at' instead of 'bit at'. This was a request.
8042 PIC16 port related preliminary changes:
8043 * gen.c: prefixed function popRegFromString with
8044 pic16_ and all references to it corrected
8045 * pcode.c: all pic16_pc_* hardware registers prefixed
8046 with underscore (_),
8047 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8048 * ralloc.c: newReg(): when register is REG_SFR then
8049 set address to rIdx,
8050 pic16_allocProcessorRegister(): marks register wasUsed=0
8051 pic16_writeUsedRegs(): added a call to assign processor
8052 registers via pic16_assignFixedRegisters
8054 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8056 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8057 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8058 variables in unused register banks. Also the SSEG is placed
8059 wherever there is enough space for it, and IDATA can be anywhere
8060 in internal RAM. For now compile using -Wl-Y[stack_size].
8061 The mem file is different for this option as well, since it
8062 makes no sense of talking about DSEG lenght.
8064 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8066 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8067 in certain cases, e.g. when ROM assignment, patch provided
8068 from Albert den Haan.
8070 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8213 * src/mcs51/peephole.def,
8214 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8309 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8311 * src/SDCCast.c (decorateType): disabled a transformation I added in
8312 revision 1.188 (access to fields of a structure at an absolute address);
8313 it breaks with bitfields, extern declarations, and gcse analysis.
8314 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8315 could be assigned through a pointer, so don't complain.
8316 * src/SDCCast.c (astErrors),
8318 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8953 * src/SDCCsymt.c (sclsFromPtr),
8955 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8956 support for standard C idiom of memory mapped variables; for
8957 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8958 to xdata int at 0x1234 tempvar = 1.
8959 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8960 provided by Akiya ISHIDA

8976 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8978 Fixed bug #621531 (const & volatile confusion in the type chain).
8979 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8980 refer to the const or volatile state of the pointer itself.

9045 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9046 pcoderegs.h, ralloc.c, ralloc.h
9047 * main.c: added top header and GPL license notice

9071 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9072 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9073 fetching of the pointer
9074 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9075 copied from genNearPointerSet()
9076 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9077 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9078 If they pop r0/r1 they must be called in the opposite order than aopOp().
9079 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9080 (resp. --stack-auto), prepared for --xstack

9091 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9093 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9094 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9095 type for bits was changed. It resulted in bit variables becoming
9096 global, which is not permitted in PIC 14 assembly output.
9098 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9100 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9102 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9104 Z80 and MCS51 linkers complaint if a public symbol is defined
9105 in more than one library module:

9111 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9113 A few small changes that speed up the peephole optimizer.
9117 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9119 Try to make the peephole optimizer smarter by maintaining
9120 an association between the assembly source code and the
9121 iCodes that originated them. Put this information to use
9122 with a new peephole rule condition "notVolatile" so that
9123 the rules can be aggressive yet still safe.
9128 * src/mcs51/peeph.def
9130 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9134 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9135 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9136 if the left or right operand symbols have the accuse flag set.
9138 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9140 Changed the type of the result of the ! (NOT) operator to char;
9141 previously it returned the same type as the source. This allows
9142 us to eliminate all the genFloatNot functions (all of its target
9143 implementations were very buggy) since !float can use the same
9146 * src/SDCCicode.c (ast2iCode): ! returns char

9148 * src/ds390/gen.c (genNot, genNotFloat),
9149 * src/z80/gen.c (genNot, genNotFloat),
9150 * src/pic/gen.c (genNot, genNotFloat),

9153 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9155 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9156 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9157 during interrupts. Ensure WSAVE is located at a shared bank address.
9158 2. Fixed page selection in some places
9159 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9160 the registers name strings.
9161 4. Fixed "signed / unsigned compare" compiler warnings.
9162 5. The PIC port manages its own allocation of the general purpose
9163 registers, but makes no attempt to reuse them. As a result when
9164 compiling it soon runs out of general purpose registers. Some
9165 additional code was added to the files pcode.c and device.c to walk
9166 through the function call tree and rename the registers so that they
9176 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9177 genPlus() & genMinus() when the result is the same as left or right
9179 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9183 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9185 Made bitfield a distinct type from bit so that bitfields
9186 convert as per ANSI C and bits retain their traditional
9187 boolean style behaviour. Implemented bitfield support in
9195 * src/ds390/gen.c: bit v bitfield split
9196 * src/z80/gen.c: New support for bitfields
9197 * support/regression/tests/bitfields.c: reenabled z80,
9200 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9202 Rules 246.x, 247.x relate to bitfields, the others speed up
9203 access to xdata mapped I/O devices.
9205 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9207 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9209 Cleaned up genPackBits and genUnpackBits and added two helper
9210 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9211 for literal assignments in genPackBits (thanks to Frieder for
9217 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9219 Fixed bug #748310 (pointer to function type mishandled when the
9220 function name is omitted). Also fixed a SIGSEGV when a function
9221 attribute (reentrant, etc) is used on a non-function or on a
9222 function but misplaced before the parameter list.
9224 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9226 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9227 * support/Util/SDCCerr.h,
9228 * support/Util/SDCCerr.c: Added func attr misuse error msg
9230 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9232 Fixed bug #787649 by anonymous
9233 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9249 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9251 Made the constant following the "interrupt" keyword optional. If
9252 omitted, the function will not automatically be given an entry
9253 in the interrupt vector table (similar to #pragma NOIV, but
9254 less syntacticly kludgy). The interrupt number is also now
9255 range checked. Also fixed a bug in the high order bit example

9263 * support/Util/SDCCerr.h
9266 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9268 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9269 * src/SDCCicode.c (operandOperation): rewritten some ops
9270 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9271 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9273 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9274 be re-activated by defining REDUCE_LITERALS)
9275 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9276 unsigned, but are signed by default
9277 * src/SDCCval.c (constVal): rearranged
9278 * src/SDCCval.c (valMod): preliminary fix
9279 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9321 constants are unsigned; added recognition of "u" flag for unsigned
9322 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9323 * src/SDCCval.c (valDiv, valMod): fixed signdness
9324 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9325 signedness of modulo, left and right shift

9376 Messed up 'configure', so revert to previous version:
9380 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
9382 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
9383 there, while the mantissa of a double is "only" 53 bits wide.

9785 added if/endif conditional macros to remove options help
9786 messages from optionsTable when a port is not configured, added
9787 support for the PIc16 port in the ports table, when executing
9788 the compiler with no port specified on command line, a default
9789 port is selected with the new macro DEFAULT_PORT which is
9790 defined in port.h, in setDefaultOptions() linkOptions is removed
9791 from initialization assignment, since now it is a set,
9792 parseCmdLine uses setParseWithComma for linkOptions, in
9793 linkEdit() linkOptions are accessed with new function indexSet()
9794 which returns the i'th item of a set variable. See SDCCset.c, in
9795 linkEdit() when calling buildCmdLine(), added linkOptions as
9796 last argument. Now users can pass arguments to gplink via the
9797 -Wl option, main() uses pic16glue() to glue up pic16 programs

9811 gpasm complaining and test the linkage with gplink, _linkCmd and
9812 _asmCmd changed to be more gplink and gpasm friendly
9813 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9814 produced an error when parsed, peep rule 12 is added to utilize
9815 movff, but it is commented out since the pCode does not support
9816 yet a command with 2 address arguments
9818 2003-05-18 <johan AT balder>
9820 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9847 2003-05-11 Borut Razem <borut.razem AT siol.net>
9849 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10857 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10858 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10859 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10861 2003-01-04 <johan AT balder>

10865 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10866 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10868 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10869 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10875 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10876 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10878 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10879 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10881 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10883 * in /sdcc/as/mcs51/ changed these files in order to create an
10884 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10885 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10886 following files to include the previous two files: aslink.dsp,
10887 Makefile.aslink, Makefile.bcc, and Makefile.in.
10889 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10890 .adb instead of .cdb
10892 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10894 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10895 value from option --iram-size.
10897 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10899 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10902 2002-09-18 <wiml AT hhhh.org>
10904 * SDCClrange.h: exposed setFromRange() and setToRange()
10905 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10906 packRegsForAccUse() (bug 542397)
10907 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10908 multiple times and emitting the fetch operations more than once
10909 added aopGetUsesAcc() function to allow binary operators to
10910 fetch their operands in the correct order; made genMinus() emit
10911 compact code for X = LITERAL - Y
10913 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10914 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10915 sprintf() in line 1267.
10917 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10918 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10921 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10922 Changes to aslink (All the changes are marked with 'JCF'):
10924 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10927 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10928 area BSEG. Also moves, if possible, the DATA area down into the internal
10929 ram so more space is available.
10931 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10934 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10935 not bytes. Function summary() which creates a memory usage summary
10936 file with extension .mem. Reports of overlaping stack and small stack
10937 size. If the space for the stack is less than 16 bytes aslink trows a
10940 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10941 the 8051. Option 'y' for memory summary output file.
10943 Changes to sdcc (All the changes are marked with 'JCF'):
10945 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10947 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10948 overlaying area for it (uses RegBankUsed[4]).
10950 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10951 bank zero as used by default. By default aslink locates the stack
10952 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10953 the creation of the .mem file. Delegates the allocation of data area
10954 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10955 the begining of the stack area to aslink.
10957 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10958 glue() in SDCCglue.c creates an area for it.
10960 2002-09-03 Borut Razem <borut.razem AT siol.net>
10961 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10962 sdcc/src/pic/glue.c:
10963 introduced atexit() handler for teporay files removal in case of
10964 errors, assertions, ...
10966 2002-08-29 Borut Razem <borut.razem AT siol.net>
10967 * sdcc/support/cpp2/auto-host_vc_in.h:
10968 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10969 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10970 Maybe there is a similar problem with BORLANDC? It should be checked!
10972 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10973 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10974 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10975 was not executed, and the compiler (cl) launched a warning:
10976 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10978 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10979 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10981 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10982 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10984 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10985 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10986 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10987 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10988 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10989 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10990 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10991 - added Release configuration in VS projects
10992 - review of compiler an linker options
10993 - VC .exe files are generated in bin_vc directory, not to interfere
10994 with binaries generated from other projects (cygwin, mingw, bcc ...)
10996 * sdcc/src/yacc.dsp: added
10998 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10999 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11000 and insert the version number definitions from .version
11002 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11004 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11005 added - genarate auto-host.h using auto-host_vc_in.h as template
11008 removed from CVS, generated automatically
11010 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11011 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11013 2002-08-11 Borut Razem <borut.razem AT siol.net>
11014 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11016 2002-08-10 Borut Razem <borut.razem AT siol.net>
11017 * src/SDCCmain.c (main):
11018 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11019 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11020 The consequence was that some temporary files were not removed.
11023 unification of code in functions tempfilename() and tempfile():
11024 function tempnam() is defined in Visual Studio 6.0 and .NET
11026 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11028 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11029 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11030 - removed compiler command line option /WX: Treats all warnings as errors
11031 - update a list of source files, included into the project
11033 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11034 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11035 changed project type to Generic Project so that can be correcly converted to VS.NET project
11037 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11039 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11041 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11043 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11044 added return 0 statements after assert() to make compiler happy
11046 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11047 added newline in the def file to keep MSC compiler satisfied
11049 * sdcc/src/z80/gen.c:
11050 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11051 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11052 - solved MSC error in function aopDump()
11054 * sdcc_vc.h: define PREFIX as "\\sdcc"
11056 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11057 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11059 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11060 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11061 - Rewrote the register banking algorithm.
11062 - Added pCode live-range analysis to registers (for now, only non-used and
11063 singly-used registers optimized away)
11065 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11067 * 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.
11069 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11082 2002-04-15 Michael Hope <michaelh AT vroom>
11084 * device/lib/z80/printf.c (sprintf): Added.
11086 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11088 * src/z80/peeph.def: Added transpose redundent load rule.
11090 * src/z80/main.c: Added force callee saves for jaune.
11092 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11094 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11096 2002-03-28 Johan Knol <johan AT balder>
11098 * src/SDCCval.c: fixed bug #532436
11100 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11102 Added "char *Processor" field to the port structure.
11105 Added -p option. Allows port dependent processor to be specified.
11108 Initialized the new field char *Processor field to NULL in all ports
11111 Compiler generated registers for interrupt context saving
11112 were not getting allocated.
11114 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11117 Fixed left shift. Will promote the left side of a left shift
11118 if a) left shifting more than size of operand or b) when assigned
11119 to something size > size of left side
11121 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11123 tons of changes. Register allocation has been
11124 rewritten. Added customization for the various PICs. Flow
11125 analysis is restructured. ...
11127 * src/pic/device.h:
11130 * src/pic/device.c:
11131 Added. device.c is a PIC port hack to accomodate variations
11134 2002-03-13 Michael Hope <michaelh AT vroom>
11136 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11138 2002-03-04 johanknol <johanknol AT manik>
11140 * /src/SDCCval.c: fixed
11142 const unsigned char arr[][2] = { { 0, 1 } };
11143 t18.c:1: error: Initializer element is not constant

11229 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11231 * sdcc/src/SDCCloop.c:
11232 Previous fix was not good. basic blocks that have "break" or "return" are
11233 not really partof a loop , but live ranges used in these blocks should
11234 be live thru the entire loop, so set partOfLoop but don't add them to
11237 2002-02-21 <johan AT FRIJA>
11239 * src/SDCCcse.c: fixed bug #514308
11241 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11244 Fixed BUG #519583. If a conditional block ended in a return/break
11245 statement inside a loop, it was not being considered part of the loop.
11247 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11249 2002-02-10 Karl Bongers <karl AT turbobit.com>
