994 Enabled VPATH feature: changed nearly all Makefiles (149 files).
995 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
997 One basic decision: e.g. src/clean.mk includes further files. In order
998 to make this work there are two solutions:
999 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1000 run configure on them. This way they can use
1001 'include $(srcdir)/port-clean.mk'
1002 - always include clean.mk by the Makefile at the same level. To avoid
1003 that `make clean` tries to include and build Makefile.dep the
1004 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1005 implemented, because now even `make uninstall` doesn't create
1006 Makefile.in. clean.mk could be eliminated by pasting it in
1009 * debugger/mcs51/Makefile.in: build own objects from library sources
1010 (SLIB, SDCC) in current directory
1012 * configure, configure.in: renamed --disable-device-lib-build in
1013 --disable-device-lib; added --enable-doc, the required tools are
1014 searched by configure; added result message; the toolchain for the
1015 belonging ports are now only built, if the port is enabled.
1017 * support/regression/*: all output is written in directory gen, because
1018 the fwk and ports directories don't livet in the build tree using vpath
1020 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1021 --disable-device-lib, added --enable-doc, added section VPATH
1023 * sim/ucsim/configure.in,
1024 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1025 z80 are enabled by default
1027 2006-04-24 Raphael Neider <rneider AT web.de>
1029 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1030 to config word, "pic14_"-prefixed some extern functions
1031 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1032 config word has been found
1033 * src/pic/device.h: added prototypes

1051 fixes #1469504 and #1474602,
1052 (pCodeRegOptimizeRegUsage): fixed typo in comment

1301 (genCritical, genEndCritical): added functions
1302 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1303 * src/z80/mappings.i: added "ei" to all mappings

1315 the left operand is shorter than the result (c* = lit-c* + int),
1317 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1320 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1322 * src/.version: increased version number to 2.5.5
1323 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1324 linking is done manually in pic16 port's _linkEdit,
1325 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1326 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1342 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1343 call to allocReg, not by manually allocating a new one,
1344 (pic16_assignRegisters): now before going through the register
1345 allocating functions mark all registers as free. This eliminates some
1346 side effects resulting from peephole parser done earlier in the backbone
1348 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1401 made the linker quiet
1403 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1405 * src/pic16/gen.c (genPcall): fixed bug #1443644
1406 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag

1408 the number of the local variables used by the specified function, added
1409 'xinst' for initial support for Extended Instruction Support,
1410 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1411 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1412 port->fun_prefix anymore (may change later),

1427 (deassignLRs): *** perhaps the most important change, old 'for' code
1428 (commented out for reference), didn't account for some registers which
1429 were left marked 'not free' after a pointer operation. The change
1430 reduces register usage a lot in some cases

3706 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3707 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,

3788 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3790 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3792 * device/lib/printf_large.c: removed inline assembly for portability and
3793 readability. Use printf_fast if speed or size are more important.
3794 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3795 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3797 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3799 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3800 prevent compiler warning
3802 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3804 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3805 moved to level 0 and declared as static. Also they are explicit
3806 placed in access bank. This was necessery because some times they
3807 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3808 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3809 optimizations. Currently only compare to unsigned char is implemented,
3810 * src/pic16/gen.c: added fReturnIdx array,
3811 * (struct resolvedIfx) is moved to gen.h and made public,
3812 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3813 * (aopForSym): added an optimization to directly store in stack of
3814 the operand of a SEND iCode,
3815 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3816 but as registers instead (AOP_REG) using the fReturnIdx array,
3817 * (pic16_freeAsmop): remove the freed register from the
3818 _G.sregsAlloc field,
3819 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3820 a compare of 'WREG',
3821 * (pic16_popGetTempRegCond): changed function prototype, now
3822 function takes also a bitVector argument v which holds the current
3823 set of registers that are allocated for stack access by aopForSym,
3824 registers allocated in aopForSym for accessing stack symbols are not
3825 any more part of the functions usedRegs field,
3826 * (genCall): some times aopOp is called for a stack variable to be
3827 send, aopForSym might perform the push, if this is true make sure
3828 that genCall doesn't push the variable twice by testing _G.resDirect,
3829 * (genFunction): changed testing for unspecified interrupt number
3830 from 256 to INTNO_UNSPEC,
3831 * modified selection scheme of frame pointer generation. Previously
3832 if function did use local registers a frame pointer was generated,
3833 now a frame pointer is generated only if function has arguments
3834 (that need PLUSW2 register access), or has stack arguments, or the
3835 compiler is not instructed to omit the frame pointer,
3836 * (genEndFunction): before restoring local registers that were saved
3837 in the function preamble, also restore the registers that *might*
3838 have been allocated for stack access,
3839 * (genRet): removed some old comments,
3840 * (genCmp, the active (RN's) version): added a call to the
3841 pic16_genCmp_special function to perform the compare with a more
3842 robust and optimized way,
3843 * (genInline): a feature has been added in inline code generation,
3844 which allows a wildcard variable substitution when writing inline
3845 assembly. Code is incomplete and experimental therefore undocumented,
3846 * (genCast): changed order of aopOp for result and right to allow
3847 aopForSym to directly load the result if possible,
3848 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3849 perform an optimized compare on some selected special occasions,
3850 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3851 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3852 generate an IVT any more,
3853 * src/pic16/main.c (pic16_optionsTable): added command line option
3855 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3856 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3858 * src/pic16/NOTES: Raphael Neider added in list of active developers
3859 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3860 jumptable_end to prevent bug #,
3861 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3862 inCond and outCond fields,
3863 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3864 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3865 turn off register spilling,
3866 * (packRegsForOneUse): synced with other ports' versions although it
3867 is not used currently,
3868 * (pic16_packRegisters): added an optimization while reading
3869 structure bitfields, some registers may be saved (malloc code is
3870 decreased by 80 bytes)
3872 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3874 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3875 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3876 this can be optimized more?
3878 2005-03-10 Raphael Neider <rneider AT web.de>
3880 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3881 genNearPointerGet): (hopefully) fixed access to bitfields via
3882 pointers (p->bitN = x; and x = p->bitN; failed)

4516 Adding support for replacing ljmps with sjmps in jumptables
4517 generated for switch statements. For now you need to set the
4518 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4519 Now 4 algorithms for mcs51 jumptable generation are used:
4520 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4521 addresses loaded pc-relative for up to 112 cases and stack-pushing
4522 target addresses loaded with offset from dptr for up to 256 cases.

4552 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4554 * added libc directory. The current version of LibC contains string
4555 functions, ctype functions and macros and some functions of the
4556 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4557 be extensively tested in the future. Standard disclaimer here.
4558 Library is not automatically build yet. But one can build it by
4559 invoking 'make' inside the libc directory.

4570 * (pic16_storeForReturn): optimized return of 0,
4571 * (genCmp): experimental code for new genCmp which uses PIC18's
4572 special compare&skip instructions. Initial tests fail some times
4573 with variables grater than 1 byte in size, so new code is disabled,
4574 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4576 * (genCast): began a fix to optimize the casting of a bit to another
4577 bit, now assigning a bitfield to another bitfield will fail, sorry,

4586 and 1 for banking instruction,
4587 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4588 caused stop processing pCodes after a inline assembly block,
4589 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4591 registers when it shouldn't,
4592 * src/pic16/ralloc.c (allocReg): add preliminary support for
4593 supporting a limited set of temporary registers,
4595 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4601 (genFunction): optimize RECEIVE iCodes in reentrant functions
4603 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7603 loaded with the linker search paths (-L arguments) and the libraries
7604 to be linked with the current source (-l arguments). Changes
7605 currently will affect only the pic16 port.
7606 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7607 include path the port specific paths and port specific libraries,
7608 * gplink command now contains the $3 argument,
7609 * src/pic16/device.h,

7626 Documenting changes from previous commits.
7627 * configure.in (version 1.56),
7628 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7629 when generating output files to configure the pic16 library,
7630 but now I've commented it out, since gputils aren't installed in the
7631 SF compile farm, so library won't compile
7633 * device/lib/Makefile.in (version 1.56): initially I've added in
7634 target 'all' the prerequestive 'model-pic16' so it compiled the
7635 pic16 library, but now I've commented it out for the same reasons
7637 * added targets 'model-pic16' and 'objects-pic16' to compile the
7639 * added target 'port-specific-objects-pic16' to handle the
7640 generated libraries and copy them into the build/ directory
7641 * added target 'clean-intermediate-pic16' to clean intermediate
7642 files into pic16 directory
7643 * in target 'installdirs' added line to create directory pic16 in

7897 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7899 A python script to validate compiler diagnostic messages. It can be
7900 used to verify that sdcc complains about bad c source code and
7901 gives a good location of the error.
7902 * support/valdiag/Makefile,
7903 * support/valdiag/valdiag.py,
7904 * support/valdiag/tests/*
7906 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7908 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7909 * src/SDCCsymt.c (newEnumType),
7911 * support/Util/SDCCerr.c,
7912 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7914 * support/regression/tests/enum.c: added test for enum values that
7915 require at least 2 bytes of storage.
7917 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7919 * src/common.h: added ifndef/define/endif macros
7920 around the header file.
7921 Bug reported from Jesus Calvino-Fraga
7923 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7925 * sdcc.spec: updated
7926 * device/include/Makefile.in: don't install CVS directories
7927 * device/lib/Makefile.in: added removal of CVS directories after install
7928 * doc/Makefile: fixed install, added local_icons
7929 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7930 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7931 * src/ds390/gen.c (genRightShift): fixed bug #870788
7932 * src/SDCCast.c (decorateType): fixed bug #870781
7934 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7936 PIC16 port related changes:
7937 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7938 added variable stackPos,
7940 * gen.c: genCall, assignResultValue: added support for
7941 pushing/retrieving function parameters to/from stack,
7942 genFunction,genEndFunction: setup stack frame for the
7944 genAddrOf: will be changed according to bug 863624
7946 * added files genutils.c and genutils.h which contain gen*
7947 debugged and optimised functions extracted from gen.c
7949 * glue.c: added variable 'externs' which holds extern symbols,
7950 pic16emitRegularMap: is modified to properly handle relocatable
7951 symbols under the new scheme,
7952 pic16createInterruptVect: is modified
7953 pic16printPublics: is modified to emit 'global' assembler directives,
7954 added pic16_printExterns to print extern symbols,
7955 pic16glue: initializes stack/frame pointer in the beginning of
7956 the assembly output. Temporary hack, will be corrected later,
7957 because gplink yet does not support stack and SDCC does not
7958 yet support a type of crt0.o object to create the final binary.
7960 * Removed many lines that contain 8051 legacy code.
7961 * The code is finally placed under a 'code' directive.
7962 * Added port specific options.
7964 * _process_pragma: simplified since now we do not need *special*
7965 include file to define SFR registers. But a separate header
7966 will be needed. This will be developed later.
7967 * _pic16_parseOptions: added, parses port specific options:
7968 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7969 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7970 --preplace-udata-with=
7972 * _pic16_setDefaultOptions: modified to initialize section names,
7973 but hack is temporarly out of order since it needs improvement.
7974 * _pic16_genAssemblerPreamble: configuration words are emitted by
7975 their address instead of their name. This part is incomplete and
7976 supports only the 18Fxx2 devices. Other devices will emit an error
7977 during assembly since they do not contain the same set of config
7979 * _pic16_genIVT: is modified,
7981 * pcode.c: added definitions for some hardware registers that are needed
7983 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7984 All PCI entries are updated. Now LFSR is supported.
7985 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7986 * added pic16_newpCodeOpLit2 to support instructions with
7987 two literal arguments
7988 * pic16_pCode2str: corrected code that emits assembler instructions
7989 with two literal operands and those that have an access bit modifier
7990 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7991 this fixes a bug which caused some labels to be lost, when an
7992 assembler directive was added, i.e. banksel,
7993 * pic16_FixRegisterBanking: improved logic that causes the insertion
7995 * InlineFunction: functions that are called once, are not any more
7996 inlined. This can be a port option in the future,
7998 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8000 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8001 hold the corresponding uninitialized symbols,
8002 * pic16_allocProcessorRegister: registers have explicit marked the
8004 * pic16_allocInternalRegister: registers are explicit marked as
8006 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8007 processing list, so bit registers were lost,
8010 * ralloc.h: added field 'accessBank' and original symbol operand
8011 in register definition,
8012 * removed the field isMapped from register definition,
8014 ** Several functions have been removed from various sources:
8015 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8016 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8017 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8018 pic16_assignRelocatableRegisters
8020 ** others have been introduced:
8021 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8022 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8024 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8026 * support/scripts/inc2h.pl: changed definition of BIT_AT
8027 to emit 'sbit at' instead of 'bit at'. This was a request.
8029 PIC16 port related preliminary changes:
8030 * gen.c: prefixed function popRegFromString with
8031 pic16_ and all references to it corrected
8032 * pcode.c: all pic16_pc_* hardware registers prefixed
8033 with underscore (_),
8034 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8035 * ralloc.c: newReg(): when register is REG_SFR then
8036 set address to rIdx,
8037 pic16_allocProcessorRegister(): marks register wasUsed=0
8038 pic16_writeUsedRegs(): added a call to assign processor
8039 registers via pic16_assignFixedRegisters
8041 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8043 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8044 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8045 variables in unused register banks. Also the SSEG is placed
8046 wherever there is enough space for it, and IDATA can be anywhere
8047 in internal RAM. For now compile using -Wl-Y[stack_size].
8048 The mem file is different for this option as well, since it
8049 makes no sense of talking about DSEG lenght.
8051 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8053 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8054 in certain cases, e.g. when ROM assignment, patch provided
8055 from Albert den Haan.
8057 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8296 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8298 * src/SDCCast.c (decorateType): disabled a transformation I added in
8299 revision 1.188 (access to fields of a structure at an absolute address);
8300 it breaks with bitfields, extern declarations, and gcse analysis.
8301 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8302 could be assigned through a pointer, so don't complain.
8303 * src/SDCCast.c (astErrors),
8305 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8943 support for standard C idiom of memory mapped variables; for
8944 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8945 to xdata int at 0x1234 tempvar = 1.
8946 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8947 provided by Akiya ISHIDA

8963 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8965 Fixed bug #621531 (const & volatile confusion in the type chain).
8966 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8967 refer to the const or volatile state of the pointer itself.

9058 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9059 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9060 fetching of the pointer
9061 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9062 copied from genNearPointerSet()
9063 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9064 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9078 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9080 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9081 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9082 type for bits was changed. It resulted in bit variables becoming
9083 global, which is not permitted in PIC 14 assembly output.
9085 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9087 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9100 A few small changes that speed up the peephole optimizer.
9104 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9106 Try to make the peephole optimizer smarter by maintaining
9107 an association between the assembly source code and the
9108 iCodes that originated them. Put this information to use
9109 with a new peephole rule condition "notVolatile" so that
9110 the rules can be aggressive yet still safe.
9115 * src/mcs51/peeph.def
9117 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9121 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9122 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9123 if the left or right operand symbols have the accuse flag set.
9125 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9127 Changed the type of the result of the ! (NOT) operator to char;
9128 previously it returned the same type as the source. This allows
9129 us to eliminate all the genFloatNot functions (all of its target
9130 implementations were very buggy) since !float can use the same
9133 * src/SDCCicode.c (ast2iCode): ! returns char

9142 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9143 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9144 during interrupts. Ensure WSAVE is located at a shared bank address.
9145 2. Fixed page selection in some places
9146 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9147 the registers name strings.
9148 4. Fixed "signed / unsigned compare" compiler warnings.
9149 5. The PIC port manages its own allocation of the general purpose
9150 registers, but makes no attempt to reuse them. As a result when
9151 compiling it soon runs out of general purpose registers. Some
9152 additional code was added to the files pcode.c and device.c to walk
9153 through the function call tree and rename the registers so that they
9163 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9164 genPlus() & genMinus() when the result is the same as left or right

9170 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9172 Made bitfield a distinct type from bit so that bitfields
9173 convert as per ANSI C and bits retain their traditional
9174 boolean style behaviour. Implemented bitfield support in
9182 * src/ds390/gen.c: bit v bitfield split
9183 * src/z80/gen.c: New support for bitfields
9184 * support/regression/tests/bitfields.c: reenabled z80,
9187 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9189 Rules 246.x, 247.x relate to bitfields, the others speed up
9190 access to xdata mapped I/O devices.
9192 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9194 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9196 Cleaned up genPackBits and genUnpackBits and added two helper
9197 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9198 for literal assignments in genPackBits (thanks to Frieder for
9204 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9206 Fixed bug #748310 (pointer to function type mishandled when the
9207 function name is omitted). Also fixed a SIGSEGV when a function
9208 attribute (reentrant, etc) is used on a non-function or on a
9209 function but misplaced before the parameter list.
9211 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9213 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9214 * support/Util/SDCCerr.h,
9215 * support/Util/SDCCerr.c: Added func attr misuse error msg

9236 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9238 Made the constant following the "interrupt" keyword optional. If
9239 omitted, the function will not automatically be given an entry
9240 in the interrupt vector table (similar to #pragma NOIV, but
9241 less syntacticly kludgy). The interrupt number is also now
9242 range checked. Also fixed a bug in the high order bit example

9256 * src/SDCCicode.c (operandOperation): rewritten some ops
9257 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9258 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9260 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9261 be re-activated by defining REDUCE_LITERALS)
9262 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9263 unsigned, but are signed by default
9264 * src/SDCCval.c (constVal): rearranged
9265 * src/SDCCval.c (valMod): preliminary fix
9266 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9772 added if/endif conditional macros to remove options help
9773 messages from optionsTable when a port is not configured, added
9774 support for the PIc16 port in the ports table, when executing
9775 the compiler with no port specified on command line, a default
9776 port is selected with the new macro DEFAULT_PORT which is
9777 defined in port.h, in setDefaultOptions() linkOptions is removed
9778 from initialization assignment, since now it is a set,
9779 parseCmdLine uses setParseWithComma for linkOptions, in
9780 linkEdit() linkOptions are accessed with new function indexSet()
9781 which returns the i'th item of a set variable. See SDCCset.c, in
9782 linkEdit() when calling buildCmdLine(), added linkOptions as
9783 last argument. Now users can pass arguments to gplink via the
9784 -Wl option, main() uses pic16glue() to glue up pic16 programs

9798 gpasm complaining and test the linkage with gplink, _linkCmd and
9799 _asmCmd changed to be more gplink and gpasm friendly
9800 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9801 produced an error when parsed, peep rule 12 is added to utilize
9802 movff, but it is commented out since the pCode does not support
9803 yet a command with 2 address arguments
9805 2003-05-18 <johan AT balder>
9807 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9834 2003-05-11 Borut Razem <borut.razem AT siol.net>
9836 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10866 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10868 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10870 * in /sdcc/as/mcs51/ changed these files in order to create an
10871 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10872 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10873 following files to include the previous two files: aslink.dsp,
10874 Makefile.aslink, Makefile.bcc, and Makefile.in.
10876 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10877 .adb instead of .cdb
10879 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10881 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10882 value from option --iram-size.
10884 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10886 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10889 2002-09-18 <wiml AT hhhh.org>
10891 * SDCClrange.h: exposed setFromRange() and setToRange()
10892 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10893 packRegsForAccUse() (bug 542397)
10894 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10895 multiple times and emitting the fetch operations more than once
10896 added aopGetUsesAcc() function to allow binary operators to
10897 fetch their operands in the correct order; made genMinus() emit
10898 compact code for X = LITERAL - Y
10900 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10901 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10902 sprintf() in line 1267.
10904 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10905 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10908 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10909 Changes to aslink (All the changes are marked with 'JCF'):
10911 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10914 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10915 area BSEG. Also moves, if possible, the DATA area down into the internal
10916 ram so more space is available.
10918 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10921 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10922 not bytes. Function summary() which creates a memory usage summary
10923 file with extension .mem. Reports of overlaping stack and small stack
10924 size. If the space for the stack is less than 16 bytes aslink trows a
10927 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10928 the 8051. Option 'y' for memory summary output file.
10930 Changes to sdcc (All the changes are marked with 'JCF'):
10932 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10934 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10935 overlaying area for it (uses RegBankUsed[4]).
10937 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10938 bank zero as used by default. By default aslink locates the stack
10939 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10940 the creation of the .mem file. Delegates the allocation of data area
10941 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10942 the begining of the stack area to aslink.
10944 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10945 glue() in SDCCglue.c creates an area for it.
10947 2002-09-03 Borut Razem <borut.razem AT siol.net>
10948 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10949 sdcc/src/pic/glue.c:
10950 introduced atexit() handler for teporay files removal in case of
10951 errors, assertions, ...
10953 2002-08-29 Borut Razem <borut.razem AT siol.net>
10954 * sdcc/support/cpp2/auto-host_vc_in.h:
10955 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10956 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10957 Maybe there is a similar problem with BORLANDC? It should be checked!
10959 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10960 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10961 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10962 was not executed, and the compiler (cl) launched a warning:
10963 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10965 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10966 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10968 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10969 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10971 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10972 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10973 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10974 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10975 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10976 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10977 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10978 - added Release configuration in VS projects
10979 - review of compiler an linker options
10980 - VC .exe files are generated in bin_vc directory, not to interfere
10981 with binaries generated from other projects (cygwin, mingw, bcc ...)
10983 * sdcc/src/yacc.dsp: added
10985 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10986 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10987 and insert the version number definitions from .version
10989 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10991 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10992 added - genarate auto-host.h using auto-host_vc_in.h as template
10995 removed from CVS, generated automatically
10997 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10998 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11000 2002-08-11 Borut Razem <borut.razem AT siol.net>
11001 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11003 2002-08-10 Borut Razem <borut.razem AT siol.net>
11004 * src/SDCCmain.c (main):
11005 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11006 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11007 The consequence was that some temporary files were not removed.
11010 unification of code in functions tempfilename() and tempfile():
11011 function tempnam() is defined in Visual Studio 6.0 and .NET
11013 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11015 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11016 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11017 - removed compiler command line option /WX: Treats all warnings as errors
11018 - update a list of source files, included into the project
11020 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11021 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11022 changed project type to Generic Project so that can be correcly converted to VS.NET project
11024 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11026 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11028 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11030 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11031 added return 0 statements after assert() to make compiler happy
11033 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11034 added newline in the def file to keep MSC compiler satisfied
11036 * sdcc/src/z80/gen.c:
11037 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11038 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11039 - solved MSC error in function aopDump()
11041 * sdcc_vc.h: define PREFIX as "\\sdcc"
11043 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11044 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11047 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11048 - Rewrote the register banking algorithm.
11049 - Added pCode live-range analysis to registers (for now, only non-used and
11050 singly-used registers optimized away)
11052 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11054 * 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.

11073 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11075 * src/z80/peeph.def: Added transpose redundent load rule.
11077 * src/z80/main.c: Added force callee saves for jaune.
11079 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11081 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11083 2002-03-28 Johan Knol <johan AT balder>
11085 * src/SDCCval.c: fixed bug #532436
11087 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11089 Added "char *Processor" field to the port structure.
11092 Added -p option. Allows port dependent processor to be specified.
11095 Initialized the new field char *Processor field to NULL in all ports
11098 Compiler generated registers for interrupt context saving
11099 were not getting allocated.
11101 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11104 Fixed left shift. Will promote the left side of a left shift
11105 if a) left shifting more than size of operand or b) when assigned
11106 to something size > size of left side
11108 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11110 tons of changes. Register allocation has been
11111 rewritten. Added customization for the various PICs. Flow
11112 analysis is restructured. ...
11114 * src/pic/device.h:
11117 * src/pic/device.c:
11118 Added. device.c is a PIC port hack to accomodate variations
11121 2002-03-13 Michael Hope <michaelh AT vroom>
11123 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11125 2002-03-04 johanknol <johanknol AT manik>
11127 * /src/SDCCval.c: fixed
11129 const unsigned char arr[][2] = { { 0, 1 } };

11216 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11218 * sdcc/src/SDCCloop.c:
11219 Previous fix was not good. basic blocks that have "break" or "return" are
11220 not really partof a loop , but live ranges used in these blocks should
11221 be live thru the entire loop, so set partOfLoop but don't add them to
11224 2002-02-21 <johan AT FRIJA>
11226 * src/SDCCcse.c: fixed bug #514308
11228 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11231 Fixed BUG #519583. If a conditional block ended in a return/break
11232 statement inside a loop, it was not being considered part of the loop.
11234 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11236 2002-02-10 Karl Bongers <karl AT turbobit.com>

11242 * device/examples/test2.c:
11243 Fix bug, "red" variable not being initialized(compiler complained).
11245 * device/examples/Makefile, examples/test3.c:
11246 Add Makefile in device/examples folder, compiles test3.c
11247 for use as a multiple module SDCDB test case.
11249 * sim/ucsim/cmd.src/cmdset.cc:
11250 Took out debug printfs in ucsim "next" command.
11252 * sim/ucsim/xa.src:
11253 Karl and Johan start ucsim XA support. Most dissassembly working,
11254 about 75% emulation done(plenty of work remaining).
11256 * sim/ucsim/z80.src:
