1019 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1020 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1022 One basic decision: e.g. src/clean.mk includes further files. In order
1023 to make this work there are two solutions:
1024 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1025 run configure on them. This way they can use
1026 'include $(srcdir)/port-clean.mk'
1027 - always include clean.mk by the Makefile at the same level. To avoid
1028 that `make clean` tries to include and build Makefile.dep the
1029 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1030 implemented, because now even `make uninstall` doesn't create
1031 Makefile.in. clean.mk could be eliminated by pasting it in
1034 * debugger/mcs51/Makefile.in: build own objects from library sources
1035 (SLIB, SDCC) in current directory
1037 * configure, configure.in: renamed --disable-device-lib-build in
1038 --disable-device-lib; added --enable-doc, the required tools are
1039 searched by configure; added result message; the toolchain for the
1040 belonging ports are now only built, if the port is enabled.
1042 * support/regression/*: all output is written in directory gen, because
1043 the fwk and ports directories don't livet in the build tree using vpath
1045 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1046 --disable-device-lib, added --enable-doc, added section VPATH
1048 * sim/ucsim/configure.in,
1049 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1050 z80 are enabled by default
1052 2006-04-24 Raphael Neider <rneider AT web.de>
1054 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1055 to config word, "pic14_"-prefixed some extern functions
1056 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1057 config word has been found
1058 * src/pic/device.h: added prototypes
1059 * src/pic/pcode.c: added "pic14_"-prefix where needed

1431 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1432 which dumps before the function entry point a data byte which represents
1433 the number of the local variables used by the specified function, added
1434 'xinst' for initial support for Extended Instruction Support,
1435 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1436 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1437 port->fun_prefix anymore (may change later),
1438 (genFunction, genEndFunction): do not store/restore local registers for
1439 _main (this should take care the --main-return command line option in
1441 (genOr): removed some legacy pic-port instructions,
1442 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1443 performing operations with SFR's causes data to be written more than

1453 (commented out for reference), didn't account for some registers which
1454 were left marked 'not free' after a pointer operation. The change
1455 reduces register usage a lot in some cases

3813 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3815 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3817 * device/lib/printf_large.c: removed inline assembly for portability and
3818 readability. Use printf_fast if speed or size are more important.
3819 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3820 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3822 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3824 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3825 prevent compiler warning
3827 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3829 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3830 moved to level 0 and declared as static. Also they are explicit
3831 placed in access bank. This was necessery because some times they
3832 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3833 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3834 optimizations. Currently only compare to unsigned char is implemented,
3835 * src/pic16/gen.c: added fReturnIdx array,
3836 * (struct resolvedIfx) is moved to gen.h and made public,
3837 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3838 * (aopForSym): added an optimization to directly store in stack of
3839 the operand of a SEND iCode,
3840 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3841 but as registers instead (AOP_REG) using the fReturnIdx array,
3842 * (pic16_freeAsmop): remove the freed register from the
3843 _G.sregsAlloc field,
3844 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3845 a compare of 'WREG',
3846 * (pic16_popGetTempRegCond): changed function prototype, now
3847 function takes also a bitVector argument v which holds the current
3848 set of registers that are allocated for stack access by aopForSym,
3849 registers allocated in aopForSym for accessing stack symbols are not
3850 any more part of the functions usedRegs field,
3851 * (genCall): some times aopOp is called for a stack variable to be
3852 send, aopForSym might perform the push, if this is true make sure
3853 that genCall doesn't push the variable twice by testing _G.resDirect,
3854 * (genFunction): changed testing for unspecified interrupt number
3855 from 256 to INTNO_UNSPEC,
3856 * modified selection scheme of frame pointer generation. Previously
3857 if function did use local registers a frame pointer was generated,
3858 now a frame pointer is generated only if function has arguments
3859 (that need PLUSW2 register access), or has stack arguments, or the
3860 compiler is not instructed to omit the frame pointer,
3861 * (genEndFunction): before restoring local registers that were saved
3862 in the function preamble, also restore the registers that *might*
3863 have been allocated for stack access,
3864 * (genRet): removed some old comments,
3865 * (genCmp, the active (RN's) version): added a call to the
3866 pic16_genCmp_special function to perform the compare with a more
3867 robust and optimized way,
3868 * (genInline): a feature has been added in inline code generation,
3869 which allows a wildcard variable substitution when writing inline
3870 assembly. Code is incomplete and experimental therefore undocumented,
3871 * (genCast): changed order of aopOp for result and right to allow
3872 aopForSym to directly load the result if possible,
3873 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3874 perform an optimized compare on some selected special occasions,
3875 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3876 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3877 generate an IVT any more,
3878 * src/pic16/main.c (pic16_optionsTable): added command line option
3880 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3881 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3883 * src/pic16/NOTES: Raphael Neider added in list of active developers
3884 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3885 jumptable_end to prevent bug #,
3886 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3887 inCond and outCond fields,
3888 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3889 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3890 turn off register spilling,

4541 Adding support for replacing ljmps with sjmps in jumptables
4542 generated for switch statements. For now you need to set the
4543 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4544 Now 4 algorithms for mcs51 jumptable generation are used:
4545 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4546 addresses loaded pc-relative for up to 112 cases and stack-pushing
4547 target addresses loaded with offset from dptr for up to 256 cases.

4577 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4579 * added libc directory. The current version of LibC contains string
4580 functions, ctype functions and macros and some functions of the
4581 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4582 be extensively tested in the future. Standard disclaimer here.
4583 Library is not automatically build yet. But one can build it by
4584 invoking 'make' inside the libc directory.

4595 * (pic16_storeForReturn): optimized return of 0,
4596 * (genCmp): experimental code for new genCmp which uses PIC18's
4597 special compare&skip instructions. Initial tests fail some times
4598 with variables grater than 1 byte in size, so new code is disabled,
4599 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4601 * (genCast): began a fix to optimize the casting of a bit to another
4602 bit, now assigning a bitfield to another bitfield will fail, sorry,

4610 * (isBankInstruction): modified to return 0 for no banking instruction,
4611 and 1 for banking instruction,
4612 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4613 caused stop processing pCodes after a inline assembly block,
4614 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4616 registers when it shouldn't,
4617 * src/pic16/ralloc.c (allocReg): add preliminary support for
4618 supporting a limited set of temporary registers,
4620 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7628 loaded with the linker search paths (-L arguments) and the libraries
7629 to be linked with the current source (-l arguments). Changes
7630 currently will affect only the pic16 port.
7631 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7632 include path the port specific paths and port specific libraries,
7633 * gplink command now contains the $3 argument,

7651 Documenting changes from previous commits.
7652 * configure.in (version 1.56),
7653 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7654 when generating output files to configure the pic16 library,
7655 but now I've commented it out, since gputils aren't installed in the
7656 SF compile farm, so library won't compile
7658 * device/lib/Makefile.in (version 1.56): initially I've added in
7659 target 'all' the prerequestive 'model-pic16' so it compiled the
7660 pic16 library, but now I've commented it out for the same reasons
7662 * added targets 'model-pic16' and 'objects-pic16' to compile the
7664 * added target 'port-specific-objects-pic16' to handle the
7665 generated libraries and copy them into the build/ directory
7666 * added target 'clean-intermediate-pic16' to clean intermediate
7667 files into pic16 directory
7668 * in target 'installdirs' added line to create directory pic16 in

7898 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
7899 how the function variable allocation summary is displayed; also
7900 include information about variables allocated to the overlay
7903 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7905 * as/mcs51/lkmain.c: Help about -Y option

7908 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7910 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
7912 * support/valdiag/tests/overflow.c: added
7913 * src/SDCCast.c (decorateType),
7914 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7915 LEFT_OP (left shift)
7917 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7919 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7920 (default behaviour).
7922 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7924 A python script to validate compiler diagnostic messages. It can be
7925 used to verify that sdcc complains about bad c source code and
7926 gives a good location of the error.
7927 * support/valdiag/Makefile,
7928 * support/valdiag/valdiag.py,
7929 * support/valdiag/tests/*
7931 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7933 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7934 * src/SDCCsymt.c (newEnumType),
7936 * support/Util/SDCCerr.c,
7937 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7939 * support/regression/tests/enum.c: added test for enum values that
7940 require at least 2 bytes of storage.
7942 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7944 * src/common.h: added ifndef/define/endif macros
7945 around the header file.
7946 Bug reported from Jesus Calvino-Fraga
7948 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7950 * sdcc.spec: updated
7951 * device/include/Makefile.in: don't install CVS directories
7952 * device/lib/Makefile.in: added removal of CVS directories after install
7953 * doc/Makefile: fixed install, added local_icons
7954 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7955 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7956 * src/ds390/gen.c (genRightShift): fixed bug #870788
7957 * src/SDCCast.c (decorateType): fixed bug #870781
7959 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7961 PIC16 port related changes:
7962 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7963 added variable stackPos,
7965 * gen.c: genCall, assignResultValue: added support for
7966 pushing/retrieving function parameters to/from stack,
7967 genFunction,genEndFunction: setup stack frame for the
7969 genAddrOf: will be changed according to bug 863624
7971 * added files genutils.c and genutils.h which contain gen*
7972 debugged and optimised functions extracted from gen.c
7974 * glue.c: added variable 'externs' which holds extern symbols,
7975 pic16emitRegularMap: is modified to properly handle relocatable
7976 symbols under the new scheme,
7977 pic16createInterruptVect: is modified
7978 pic16printPublics: is modified to emit 'global' assembler directives,
7979 added pic16_printExterns to print extern symbols,
7980 pic16glue: initializes stack/frame pointer in the beginning of
7981 the assembly output. Temporary hack, will be corrected later,
7982 because gplink yet does not support stack and SDCC does not
7983 yet support a type of crt0.o object to create the final binary.
7985 * Removed many lines that contain 8051 legacy code.
7986 * The code is finally placed under a 'code' directive.
7987 * Added port specific options.
7989 * _process_pragma: simplified since now we do not need *special*
7990 include file to define SFR registers. But a separate header
7991 will be needed. This will be developed later.
7992 * _pic16_parseOptions: added, parses port specific options:
7993 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7994 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7995 --preplace-udata-with=
7997 * _pic16_setDefaultOptions: modified to initialize section names,
7998 but hack is temporarly out of order since it needs improvement.
7999 * _pic16_genAssemblerPreamble: configuration words are emitted by
8000 their address instead of their name. This part is incomplete and
8001 supports only the 18Fxx2 devices. Other devices will emit an error
8002 during assembly since they do not contain the same set of config
8004 * _pic16_genIVT: is modified,
8006 * pcode.c: added definitions for some hardware registers that are needed
8008 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8009 All PCI entries are updated. Now LFSR is supported.
8010 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8011 * added pic16_newpCodeOpLit2 to support instructions with
8012 two literal arguments
8013 * pic16_pCode2str: corrected code that emits assembler instructions
8014 with two literal operands and those that have an access bit modifier
8015 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8016 this fixes a bug which caused some labels to be lost, when an
8017 assembler directive was added, i.e. banksel,
8018 * pic16_FixRegisterBanking: improved logic that causes the insertion
8020 * InlineFunction: functions that are called once, are not any more
8021 inlined. This can be a port option in the future,
8023 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8025 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8026 hold the corresponding uninitialized symbols,
8027 * pic16_allocProcessorRegister: registers have explicit marked the
8029 * pic16_allocInternalRegister: registers are explicit marked as
8031 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8032 processing list, so bit registers were lost,
8035 * ralloc.h: added field 'accessBank' and original symbol operand
8036 in register definition,
8037 * removed the field isMapped from register definition,
8039 ** Several functions have been removed from various sources:
8040 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8041 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8042 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8043 pic16_assignRelocatableRegisters
8045 ** others have been introduced:
8046 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8047 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8049 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8051 * support/scripts/inc2h.pl: changed definition of BIT_AT
8052 to emit 'sbit at' instead of 'bit at'. This was a request.
8054 PIC16 port related preliminary changes:
8055 * gen.c: prefixed function popRegFromString with
8056 pic16_ and all references to it corrected
8057 * pcode.c: all pic16_pc_* hardware registers prefixed
8058 with underscore (_),
8059 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8060 * ralloc.c: newReg(): when register is REG_SFR then
8061 set address to rIdx,
8062 pic16_allocProcessorRegister(): marks register wasUsed=0
8063 pic16_writeUsedRegs(): added a call to assign processor
8064 registers via pic16_assignFixedRegisters
8066 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8068 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8069 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8070 variables in unused register banks. Also the SSEG is placed
8071 wherever there is enough space for it, and IDATA can be anywhere
8072 in internal RAM. For now compile using -Wl-Y[stack_size].
8073 The mem file is different for this option as well, since it
8074 makes no sense of talking about DSEG lenght.
8076 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8078 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8079 in certain cases, e.g. when ROM assignment, patch provided
8080 from Albert den Haan.

8225 * src/mcs51/peephole.def,
8226 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8238 multiply defined with mismatching "at" address.
8240 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8242 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8321 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8323 * src/SDCCast.c (decorateType): disabled a transformation I added in
8324 revision 1.188 (access to fields of a structure at an absolute address);
8325 it breaks with bitfields, extern declarations, and gcse analysis.
8326 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8327 could be assigned through a pointer, so don't complain.
8328 * src/SDCCast.c (astErrors),
8330 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8967 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8968 support for standard C idiom of memory mapped variables; for
8969 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8970 to xdata int at 0x1234 tempvar = 1.
8971 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8972 provided by Akiya ISHIDA

9083 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9084 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9085 fetching of the pointer
9086 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9087 copied from genNearPointerSet()
9088 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9089 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9105 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9106 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9107 type for bits was changed. It resulted in bit variables becoming
9108 global, which is not permitted in PIC 14 assembly output.
9110 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9125 A few small changes that speed up the peephole optimizer.
9129 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9131 Try to make the peephole optimizer smarter by maintaining
9132 an association between the assembly source code and the
9133 iCodes that originated them. Put this information to use
9134 with a new peephole rule condition "notVolatile" so that
9135 the rules can be aggressive yet still safe.
9140 * src/mcs51/peeph.def
9142 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9146 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9147 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9148 if the left or right operand symbols have the accuse flag set.
9150 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9152 Changed the type of the result of the ! (NOT) operator to char;
9153 previously it returned the same type as the source. This allows
9154 us to eliminate all the genFloatNot functions (all of its target
9155 implementations were very buggy) since !float can use the same

9167 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9168 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9169 during interrupts. Ensure WSAVE is located at a shared bank address.
9170 2. Fixed page selection in some places
9171 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9172 the registers name strings.
9173 4. Fixed "signed / unsigned compare" compiler warnings.
9174 5. The PIC port manages its own allocation of the general purpose
9175 registers, but makes no attempt to reuse them. As a result when
9176 compiling it soon runs out of general purpose registers. Some
9177 additional code was added to the files pcode.c and device.c to walk
9178 through the function call tree and rename the registers so that they
9188 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9189 genPlus() & genMinus() when the result is the same as left or right

9195 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9197 Made bitfield a distinct type from bit so that bitfields
9198 convert as per ANSI C and bits retain their traditional
9199 boolean style behaviour. Implemented bitfield support in
9207 * src/ds390/gen.c: bit v bitfield split
9208 * src/z80/gen.c: New support for bitfields
9209 * support/regression/tests/bitfields.c: reenabled z80,
9212 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9214 Rules 246.x, 247.x relate to bitfields, the others speed up
9215 access to xdata mapped I/O devices.
9217 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9219 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9221 Cleaned up genPackBits and genUnpackBits and added two helper
9222 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9223 for literal assignments in genPackBits (thanks to Frieder for
9229 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9231 Fixed bug #748310 (pointer to function type mishandled when the
9232 function name is omitted). Also fixed a SIGSEGV when a function
9233 attribute (reentrant, etc) is used on a non-function or on a
9234 function but misplaced before the parameter list.
9236 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9238 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9239 * support/Util/SDCCerr.h,

9261 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9263 Made the constant following the "interrupt" keyword optional. If
9264 omitted, the function will not automatically be given an entry
9265 in the interrupt vector table (similar to #pragma NOIV, but
9266 less syntacticly kludgy). The interrupt number is also now
9267 range checked. Also fixed a bug in the high order bit example

9281 * src/SDCCicode.c (operandOperation): rewritten some ops
9282 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9283 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9285 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9286 be re-activated by defining REDUCE_LITERALS)

9288 unsigned, but are signed by default
9289 * src/SDCCval.c (constVal): rearranged
9290 * src/SDCCval.c (valMod): preliminary fix
9291 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9333 constants are unsigned; added recognition of "u" flag for unsigned
9334 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9335 * src/SDCCval.c (valDiv, valMod): fixed signdness

9797 added if/endif conditional macros to remove options help
9798 messages from optionsTable when a port is not configured, added
9799 support for the PIc16 port in the ports table, when executing
9800 the compiler with no port specified on command line, a default
9801 port is selected with the new macro DEFAULT_PORT which is
9802 defined in port.h, in setDefaultOptions() linkOptions is removed
9803 from initialization assignment, since now it is a set,
9804 parseCmdLine uses setParseWithComma for linkOptions, in
9805 linkEdit() linkOptions are accessed with new function indexSet()
9806 which returns the i'th item of a set variable. See SDCCset.c, in
9807 linkEdit() when calling buildCmdLine(), added linkOptions as
9808 last argument. Now users can pass arguments to gplink via the
9809 -Wl option, main() uses pic16glue() to glue up pic16 programs

9823 gpasm complaining and test the linkage with gplink, _linkCmd and
9824 _asmCmd changed to be more gplink and gpasm friendly
9825 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9826 produced an error when parsed, peep rule 12 is added to utilize
9827 movff, but it is commented out since the pCode does not support
9828 yet a command with 2 address arguments
9830 2003-05-18 <johan AT balder>
9832 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10807 2003-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10809 * src/SDCCmain.c (main): port->finaliseOptions() moved for z80 linking
10810 * src/SDCCutil.c (join): ugly bug: missing '\0'

10852 * src/SDCCast.c (decorateType): fixed bug #600035
10854 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10855 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10856 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

10867 * src/SDCCicode.c: fixed array add
10869 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10870 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10871 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10873 2003-01-04 <johan AT balder>

10877 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10878 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10880 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10881 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10882 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10884 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10885 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10887 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10888 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10890 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10891 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10893 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10895 * in /sdcc/as/mcs51/ changed these files in order to create an
10896 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10897 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10898 following files to include the previous two files: aslink.dsp,
10899 Makefile.aslink, Makefile.bcc, and Makefile.in.
10901 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10902 .adb instead of .cdb
10904 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10906 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10907 value from option --iram-size.
10909 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10911 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10914 2002-09-18 <wiml AT hhhh.org>
10916 * SDCClrange.h: exposed setFromRange() and setToRange()
10917 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10918 packRegsForAccUse() (bug 542397)
10919 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10920 multiple times and emitting the fetch operations more than once
10921 added aopGetUsesAcc() function to allow binary operators to
10922 fetch their operands in the correct order; made genMinus() emit
10923 compact code for X = LITERAL - Y
10925 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10926 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10927 sprintf() in line 1267.
10929 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10930 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10933 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10934 Changes to aslink (All the changes are marked with 'JCF'):
10936 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10939 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10940 area BSEG. Also moves, if possible, the DATA area down into the internal
10941 ram so more space is available.
10943 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10946 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10947 not bytes. Function summary() which creates a memory usage summary
10948 file with extension .mem. Reports of overlaping stack and small stack
10949 size. If the space for the stack is less than 16 bytes aslink trows a
10952 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10953 the 8051. Option 'y' for memory summary output file.
10955 Changes to sdcc (All the changes are marked with 'JCF'):
10957 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10959 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10960 overlaying area for it (uses RegBankUsed[4]).
10962 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10963 bank zero as used by default. By default aslink locates the stack
10964 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10965 the creation of the .mem file. Delegates the allocation of data area
10966 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10967 the begining of the stack area to aslink.
10969 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10970 glue() in SDCCglue.c creates an area for it.
10972 2002-09-03 Borut Razem <borut.razem AT siol.net>
10973 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10974 sdcc/src/pic/glue.c:
10975 introduced atexit() handler for teporay files removal in case of
10976 errors, assertions, ...
10978 2002-08-29 Borut Razem <borut.razem AT siol.net>
10979 * sdcc/support/cpp2/auto-host_vc_in.h:
10980 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10981 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10982 Maybe there is a similar problem with BORLANDC? It should be checked!
10984 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10985 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10986 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10987 was not executed, and the compiler (cl) launched a warning:
10988 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10990 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10991 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10993 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10994 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10996 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10997 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10998 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10999 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11000 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11001 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11002 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11003 - added Release configuration in VS projects
11004 - review of compiler an linker options
11005 - VC .exe files are generated in bin_vc directory, not to interfere
11006 with binaries generated from other projects (cygwin, mingw, bcc ...)
11008 * sdcc/src/yacc.dsp: added
11010 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11011 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11012 and insert the version number definitions from .version
11014 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11016 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11017 added - genarate auto-host.h using auto-host_vc_in.h as template
11020 removed from CVS, generated automatically
11022 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11023 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11025 2002-08-11 Borut Razem <borut.razem AT siol.net>
11026 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11028 2002-08-10 Borut Razem <borut.razem AT siol.net>
11029 * src/SDCCmain.c (main):
11030 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11031 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11032 The consequence was that some temporary files were not removed.
11035 unification of code in functions tempfilename() and tempfile():
11036 function tempnam() is defined in Visual Studio 6.0 and .NET
11038 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11040 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11041 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11042 - removed compiler command line option /WX: Treats all warnings as errors
11043 - update a list of source files, included into the project
11045 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11046 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11047 changed project type to Generic Project so that can be correcly converted to VS.NET project
11049 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11051 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11053 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11055 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11056 added return 0 statements after assert() to make compiler happy
11058 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11059 added newline in the def file to keep MSC compiler satisfied
11061 * sdcc/src/z80/gen.c:
11062 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11063 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11064 - solved MSC error in function aopDump()
11066 * sdcc_vc.h: define PREFIX as "\\sdcc"
11068 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11069 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11071 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11072 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11073 - Rewrote the register banking algorithm.
11074 - Added pCode live-range analysis to registers (for now, only non-used and
11075 singly-used registers optimized away)
11077 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11079 * 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.

11094 2002-04-15 Michael Hope <michaelh AT vroom>
11096 * device/lib/z80/printf.c (sprintf): Added.
11098 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11100 * src/z80/peeph.def: Added transpose redundent load rule.
11102 * src/z80/main.c: Added force callee saves for jaune.
11104 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11106 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11108 2002-03-28 Johan Knol <johan AT balder>
11110 * src/SDCCval.c: fixed bug #532436
11112 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11114 Added "char *Processor" field to the port structure.
11117 Added -p option. Allows port dependent processor to be specified.
11120 Initialized the new field char *Processor field to NULL in all ports
11123 Compiler generated registers for interrupt context saving
11124 were not getting allocated.
11126 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11129 Fixed left shift. Will promote the left side of a left shift
11130 if a) left shifting more than size of operand or b) when assigned
11131 to something size > size of left side
11133 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11135 tons of changes. Register allocation has been
11136 rewritten. Added customization for the various PICs. Flow
11137 analysis is restructured. ...
11139 * src/pic/device.h:
11142 * src/pic/device.c:
11143 Added. device.c is a PIC port hack to accomodate variations
11146 2002-03-13 Michael Hope <michaelh AT vroom>
11148 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11150 2002-03-04 johanknol <johanknol AT manik>
11152 * /src/SDCCval.c: fixed
11154 const unsigned char arr[][2] = { { 0, 1 } };
11155 t18.c:1: error: Initializer element is not constant

11213 * src/z80/ralloc.c (packRegsForIYUse): Fixed fp bug where four byte operands were packed into IY.
11215 2002-03-01 <johan AT FRIJA>
11217 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
11219 * src/SDCCast.c (decorateType): fixed bug #524209

11241 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11243 * sdcc/src/SDCCloop.c:
11244 Previous fix was not good. basic blocks that have "break" or "return" are
11245 not really partof a loop , but live ranges used in these blocks should
11246 be live thru the entire loop, so set partOfLoop but don't add them to
11249 2002-02-21 <johan AT FRIJA>
