940 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
942 Enabled VPATH feature: changed nearly all Makefiles (149 files).
943 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
945 One basic decision: e.g. src/clean.mk includes further files. In order
946 to make this work there are two solutions:
947 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
948 run configure on them. This way they can use
949 'include $(srcdir)/port-clean.mk'
950 - always include clean.mk by the Makefile at the same level. To avoid
951 that `make clean` tries to include and build Makefile.dep the
952 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
953 implemented, because now even `make uninstall` doesn't create
954 Makefile.in. clean.mk could be eliminated by pasting it in
957 * debugger/mcs51/Makefile.in: build own objects from library sources
958 (SLIB, SDCC) in current directory
960 * configure, configure.in: renamed --disable-device-lib-build in
961 --disable-device-lib; added --enable-doc, the required tools are
962 searched by configure; added result message; the toolchain for the
963 belonging ports are now only built, if the port is enabled.
965 * support/regression/*: all output is written in directory gen, because
966 the fwk and ports directories don't livet in the build tree using vpath
968 * doc/sdccman.lyx: renamed --disable-device-lib-build to
969 --disable-device-lib, added --enable-doc, added section VPATH
971 * sim/ucsim/configure.in,
972 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
973 z80 are enabled by default
975 2006-04-24 Raphael Neider <rneider AT web.de>
977 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
978 to config word, "pic14_"-prefixed some extern functions
979 (pic14_emitConfigWord): emit __config directive(s) if assignment to
980 config word has been found
981 * src/pic/device.h: added prototypes
982 * src/pic/pcode.c: added "pic14_"-prefix where needed
983 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
985 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1290 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1291 call to allocReg, not by manually allocating a new one,
1292 (pic16_assignRegisters): now before going through the register
1293 allocating functions mark all registers as free. This eliminates some
1294 side effects resulting from peephole parser done earlier in the backbone

1351 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1353 * src/pic16/gen.c (genPcall): fixed bug #1443644
1354 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1355 which dumps before the function entry point a data byte which represents
1356 the number of the local variables used by the specified function, added
1357 'xinst' for initial support for Extended Instruction Support,
1358 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1359 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1360 port->fun_prefix anymore (may change later),
1361 (genFunction, genEndFunction): do not store/restore local registers for
1362 _main (this should take care the --main-return command line option in
1364 (genOr): removed some legacy pic-port instructions,
1365 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1366 performing operations with SFR's causes data to be written more than
1367 once to each SFR. Perhaps SFRs should be handled in special cases...
1368 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1370 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1371 into account for stack starting position,
1372 (struct OPTIONS pic16_optionsTable): added command line argument
1373 --extended or -y for Extended Instruction Support,
1374 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1375 (deassignLRs): *** perhaps the most important change, old 'for' code
1376 (commented out for reference), didn't account for some registers which
1377 were left marked 'not free' after a pointer operation. The change
1378 reduces register usage a lot in some cases

3653 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3654 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3655 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3656 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3657 always available in leading double underscore form. The C99 support is
3658 mostly missing, but it's a start.
3659 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3660 reserved identifier "__data".

3738 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3740 * device/lib/printf_large.c: removed inline assembly for portability and
3741 readability. Use printf_fast if speed or size are more important.
3742 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3743 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3745 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3747 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3748 prevent compiler warning
3750 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3752 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3753 moved to level 0 and declared as static. Also they are explicit
3754 placed in access bank. This was necessery because some times they
3755 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3756 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3757 optimizations. Currently only compare to unsigned char is implemented,
3758 * src/pic16/gen.c: added fReturnIdx array,
3759 * (struct resolvedIfx) is moved to gen.h and made public,
3760 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3761 * (aopForSym): added an optimization to directly store in stack of
3762 the operand of a SEND iCode,
3763 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3764 but as registers instead (AOP_REG) using the fReturnIdx array,
3765 * (pic16_freeAsmop): remove the freed register from the
3766 _G.sregsAlloc field,
3767 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3768 a compare of 'WREG',
3769 * (pic16_popGetTempRegCond): changed function prototype, now
3770 function takes also a bitVector argument v which holds the current
3771 set of registers that are allocated for stack access by aopForSym,
3772 registers allocated in aopForSym for accessing stack symbols are not
3773 any more part of the functions usedRegs field,
3774 * (genCall): some times aopOp is called for a stack variable to be
3775 send, aopForSym might perform the push, if this is true make sure
3776 that genCall doesn't push the variable twice by testing _G.resDirect,
3777 * (genFunction): changed testing for unspecified interrupt number
3778 from 256 to INTNO_UNSPEC,
3779 * modified selection scheme of frame pointer generation. Previously
3780 if function did use local registers a frame pointer was generated,
3781 now a frame pointer is generated only if function has arguments
3782 (that need PLUSW2 register access), or has stack arguments, or the
3783 compiler is not instructed to omit the frame pointer,
3784 * (genEndFunction): before restoring local registers that were saved
3785 in the function preamble, also restore the registers that *might*
3786 have been allocated for stack access,
3787 * (genRet): removed some old comments,
3788 * (genCmp, the active (RN's) version): added a call to the
3789 pic16_genCmp_special function to perform the compare with a more
3790 robust and optimized way,
3791 * (genInline): a feature has been added in inline code generation,
3792 which allows a wildcard variable substitution when writing inline
3793 assembly. Code is incomplete and experimental therefore undocumented,
3794 * (genCast): changed order of aopOp for result and right to allow
3795 aopForSym to directly load the result if possible,
3796 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3797 perform an optimized compare on some selected special occasions,
3798 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3799 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3800 generate an IVT any more,
3801 * src/pic16/main.c (pic16_optionsTable): added command line option
3803 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3804 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3806 * src/pic16/NOTES: Raphael Neider added in list of active developers
3807 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3808 jumptable_end to prevent bug #,
3809 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3810 inCond and outCond fields,
3811 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3812 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3813 turn off register spilling,
3814 * (packRegsForOneUse): synced with other ports' versions although it
3815 is not used currently,
3816 * (pic16_packRegisters): added an optimization while reading
3817 structure bitfields, some registers may be saved (malloc code is
3818 decreased by 80 bytes)
3820 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3822 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3823 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3824 this can be optimized more?
3826 2005-03-10 Raphael Neider <rneider AT web.de>
3828 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3829 genNearPointerGet): (hopefully) fixed access to bitfields via
3830 pointers (p->bitN = x; and x = p->bitN; failed)
3832 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3834 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3873 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3875 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3876 to keep the correct label reference count when adding/removing references
3877 to labels. A peephole file using this is appended to patch #1144962.
3879 2005-02-14 Raphael Neider <rneider AT web.de>

4464 Adding support for replacing ljmps with sjmps in jumptables
4465 generated for switch statements. For now you need to set the
4466 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4467 Now 4 algorithms for mcs51 jumptable generation are used:
4468 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4469 addresses loaded pc-relative for up to 112 cases and stack-pushing
4470 target addresses loaded with offset from dptr for up to 256 cases.

4500 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4502 * added libc directory. The current version of LibC contains string
4503 functions, ctype functions and macros and some functions of the
4504 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4505 be extensively tested in the future. Standard disclaimer here.
4506 Library is not automatically build yet. But one can build it by
4507 invoking 'make' inside the libc directory.
4508 * added ADC library under libio. Preliminary version yet.

4518 * (pic16_storeForReturn): optimized return of 0,
4519 * (genCmp): experimental code for new genCmp which uses PIC18's
4520 special compare&skip instructions. Initial tests fail some times
4521 with variables grater than 1 byte in size, so new code is disabled,
4522 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4524 * (genCast): began a fix to optimize the casting of a bit to another
4525 bit, now assigning a bitfield to another bitfield will fail, sorry,
4526 * src/pic16/main.c: disabled the use of lr-support feature,
4527 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4530 bits with offset (case PO_GPR_BIT),
4531 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4533 * (isBankInstruction): modified to return 0 for no banking instruction,
4534 and 1 for banking instruction,
4535 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4536 caused stop processing pCodes after a inline assembly block,
4537 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4538 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4539 registers when it shouldn't,
4540 * src/pic16/ralloc.c (allocReg): add preliminary support for
4541 supporting a limited set of temporary registers,
4543 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4545 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4546 genDataPointerSet): ensure assignments always copy in MSB to LSB
4548 (loadRegFromAop): recognize CLRH optimization,
4549 (genFunction): optimize RECEIVE iCodes in reentrant functions
4551 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4553 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7551 loaded with the linker search paths (-L arguments) and the libraries
7552 to be linked with the current source (-l arguments). Changes
7553 currently will affect only the pic16 port.
7554 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7555 include path the port specific paths and port specific libraries,
7556 * gplink command now contains the $3 argument,
7557 * src/pic16/device.h,

7574 Documenting changes from previous commits.
7575 * configure.in (version 1.56),
7576 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7577 when generating output files to configure the pic16 library,
7578 but now I've commented it out, since gputils aren't installed in the
7579 SF compile farm, so library won't compile
7581 * device/lib/Makefile.in (version 1.56): initially I've added in
7582 target 'all' the prerequestive 'model-pic16' so it compiled the
7583 pic16 library, but now I've commented it out for the same reasons
7585 * added targets 'model-pic16' and 'objects-pic16' to compile the
7587 * added target 'port-specific-objects-pic16' to handle the
7588 generated libraries and copy them into the build/ directory
7589 * added target 'clean-intermediate-pic16' to clean intermediate
7590 files into pic16 directory
7591 * in target 'installdirs' added line to create directory pic16 in

7902 added pic16_printExterns to print extern symbols,
7903 pic16glue: initializes stack/frame pointer in the beginning of
7904 the assembly output. Temporary hack, will be corrected later,
7905 because gplink yet does not support stack and SDCC does not
7906 yet support a type of crt0.o object to create the final binary.
7908 * Removed many lines that contain 8051 legacy code.
7909 * The code is finally placed under a 'code' directive.
7910 * Added port specific options.
7912 * _process_pragma: simplified since now we do not need *special*
7913 include file to define SFR registers. But a separate header
7914 will be needed. This will be developed later.
7915 * _pic16_parseOptions: added, parses port specific options:
7916 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7917 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7918 --preplace-udata-with=
7920 * _pic16_setDefaultOptions: modified to initialize section names,
7921 but hack is temporarly out of order since it needs improvement.
7922 * _pic16_genAssemblerPreamble: configuration words are emitted by
7923 their address instead of their name. This part is incomplete and
7924 supports only the 18Fxx2 devices. Other devices will emit an error
7925 during assembly since they do not contain the same set of config
7927 * _pic16_genIVT: is modified,
7929 * pcode.c: added definitions for some hardware registers that are needed
7931 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7932 All PCI entries are updated. Now LFSR is supported.
7933 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7934 * added pic16_newpCodeOpLit2 to support instructions with
7935 two literal arguments
7936 * pic16_pCode2str: corrected code that emits assembler instructions
7937 with two literal operands and those that have an access bit modifier
7938 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7939 this fixes a bug which caused some labels to be lost, when an
7940 assembler directive was added, i.e. banksel,
7941 * pic16_FixRegisterBanking: improved logic that causes the insertion
7943 * InlineFunction: functions that are called once, are not any more
7944 inlined. This can be a port option in the future,
7946 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7948 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7949 hold the corresponding uninitialized symbols,
7950 * pic16_allocProcessorRegister: registers have explicit marked the
7952 * pic16_allocInternalRegister: registers are explicit marked as
7954 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7955 processing list, so bit registers were lost,
7958 * ralloc.h: added field 'accessBank' and original symbol operand
7959 in register definition,
7960 * removed the field isMapped from register definition,
7962 ** Several functions have been removed from various sources:
7963 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7964 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7965 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7966 pic16_assignRelocatableRegisters
7968 ** others have been introduced:
7969 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7970 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7972 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7974 * support/scripts/inc2h.pl: changed definition of BIT_AT
7975 to emit 'sbit at' instead of 'bit at'. This was a request.
7977 PIC16 port related preliminary changes:
7978 * gen.c: prefixed function popRegFromString with
7979 pic16_ and all references to it corrected
7980 * pcode.c: all pic16_pc_* hardware registers prefixed
7981 with underscore (_),
7982 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7983 * ralloc.c: newReg(): when register is REG_SFR then
7984 set address to rIdx,
7985 pic16_allocProcessorRegister(): marks register wasUsed=0
7986 pic16_writeUsedRegs(): added a call to assign processor
7987 registers via pic16_assignFixedRegisters
7989 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7991 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7992 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7993 variables in unused register banks. Also the SSEG is placed
7994 wherever there is enough space for it, and IDATA can be anywhere
7995 in internal RAM. For now compile using -Wl-Y[stack_size].
7996 The mem file is different for this option as well, since it
7997 makes no sense of talking about DSEG lenght.
7999 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8001 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8002 in certain cases, e.g. when ROM assignment, patch provided
8003 from Albert den Haan.

8244 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8246 * src/SDCCast.c (decorateType): disabled a transformation I added in
8247 revision 1.188 (access to fields of a structure at an absolute address);
8248 it breaks with bitfields, extern declarations, and gcse analysis.
8249 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8250 could be assigned through a pointer, so don't complain.
8251 * src/SDCCast.c (astErrors),
8253 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8355 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8356 uninitialized variables) for the mcs51. Set environment variable
8357 SDCC_GENRAMCLEAR to test.
8358 xdata initialization slightly shorter
8360 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9007 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9008 fetching of the pointer
9009 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9010 copied from genNearPointerSet()
9011 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9012 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9028 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9029 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9030 type for bits was changed. It resulted in bit variables becoming
9031 global, which is not permitted in PIC 14 assembly output.

9048 A few small changes that speed up the peephole optimizer.
9052 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9054 Try to make the peephole optimizer smarter by maintaining
9055 an association between the assembly source code and the
9056 iCodes that originated them. Put this information to use
9057 with a new peephole rule condition "notVolatile" so that
9058 the rules can be aggressive yet still safe.
9063 * src/mcs51/peeph.def
9065 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9069 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

9071 if the left or right operand symbols have the accuse flag set.
9073 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9075 Changed the type of the result of the ! (NOT) operator to char;
9076 previously it returned the same type as the source. This allows
9077 us to eliminate all the genFloatNot functions (all of its target
9078 implementations were very buggy) since !float can use the same

9090 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9091 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9092 during interrupts. Ensure WSAVE is located at a shared bank address.
9093 2. Fixed page selection in some places
9094 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9095 the registers name strings.
9096 4. Fixed "signed / unsigned compare" compiler warnings.
9097 5. The PIC port manages its own allocation of the general purpose
9098 registers, but makes no attempt to reuse them. As a result when
9099 compiling it soon runs out of general purpose registers. Some
9100 additional code was added to the files pcode.c and device.c to walk
9101 through the function call tree and rename the registers so that they
9111 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9118 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9120 Made bitfield a distinct type from bit so that bitfields
9121 convert as per ANSI C and bits retain their traditional
9122 boolean style behaviour. Implemented bitfield support in
9130 * src/ds390/gen.c: bit v bitfield split
9131 * src/z80/gen.c: New support for bitfields
9132 * support/regression/tests/bitfields.c: reenabled z80,
9135 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9137 Rules 246.x, 247.x relate to bitfields, the others speed up
9138 access to xdata mapped I/O devices.
9140 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9142 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9144 Cleaned up genPackBits and genUnpackBits and added two helper
9145 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9146 for literal assignments in genPackBits (thanks to Frieder for
9152 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9154 Fixed bug #748310 (pointer to function type mishandled when the
9155 function name is omitted). Also fixed a SIGSEGV when a function
9156 attribute (reentrant, etc) is used on a non-function or on a
9157 function but misplaced before the parameter list.
9159 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9161 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9162 * support/Util/SDCCerr.h,

9184 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9186 Made the constant following the "interrupt" keyword optional. If
9187 omitted, the function will not automatically be given an entry
9188 in the interrupt vector table (similar to #pragma NOIV, but
9189 less syntacticly kludgy). The interrupt number is also now
9190 range checked. Also fixed a bug in the high order bit example

9204 * src/SDCCicode.c (operandOperation): rewritten some ops
9205 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9206 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9208 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9209 be re-activated by defining REDUCE_LITERALS)
9210 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9211 unsigned, but are signed by default
9212 * src/SDCCval.c (constVal): rearranged
9213 * src/SDCCval.c (valMod): preliminary fix
9214 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9256 constants are unsigned; added recognition of "u" flag for unsigned
9257 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9258 * src/SDCCval.c (valDiv, valMod): fixed signdness

9719 * src/SDCCmain.c: linkOptions is changed to set *,
9720 added if/endif conditional macros to remove options help
9721 messages from optionsTable when a port is not configured, added
9722 support for the PIc16 port in the ports table, when executing
9723 the compiler with no port specified on command line, a default
9724 port is selected with the new macro DEFAULT_PORT which is
9725 defined in port.h, in setDefaultOptions() linkOptions is removed
9726 from initialization assignment, since now it is a set,
9727 parseCmdLine uses setParseWithComma for linkOptions, in
9728 linkEdit() linkOptions are accessed with new function indexSet()
9729 which returns the i'th item of a set variable. See SDCCset.c, in
9730 linkEdit() when calling buildCmdLine(), added linkOptions as
9731 last argument. Now users can pass arguments to gplink via the
9732 -Wl option, main() uses pic16glue() to glue up pic16 programs

9744 * src/pic16/glue.c: commented out some error producing lines
9745 * src/pic16/main.c: __config directives are commented out to stop
9746 gpasm complaining and test the linkage with gplink, _linkCmd and
9747 _asmCmd changed to be more gplink and gpasm friendly
9748 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9749 produced an error when parsed, peep rule 12 is added to utilize
9750 movff, but it is commented out since the pCode does not support
9751 yet a command with 2 address arguments
9753 2003-05-18 <johan AT balder>
9755 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9782 2003-05-11 Borut Razem <borut.razem AT siol.net>
9784 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9785 the path of bin directory, so that PATH is the only env. variable, which has to be set
9786 in case of standard installation.

10788 2003-01-06 <johan AT balder>
10790 * src/SDCCicode.c: fixed array add
10792 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10793 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10794 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10796 2003-01-04 <johan AT balder>
10798 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10800 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10801 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10803 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10804 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10805 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10807 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10808 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10810 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10811 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10813 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10814 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10816 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10818 * in /sdcc/as/mcs51/ changed these files in order to create an
10819 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10820 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10821 following files to include the previous two files: aslink.dsp,
10822 Makefile.aslink, Makefile.bcc, and Makefile.in.
10824 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10825 .adb instead of .cdb
10827 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10829 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10830 value from option --iram-size.
10832 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10834 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10837 2002-09-18 <wiml AT hhhh.org>
10839 * SDCClrange.h: exposed setFromRange() and setToRange()
10840 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10841 packRegsForAccUse() (bug 542397)
10842 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10843 multiple times and emitting the fetch operations more than once
10844 added aopGetUsesAcc() function to allow binary operators to
10845 fetch their operands in the correct order; made genMinus() emit
10846 compact code for X = LITERAL - Y
10848 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10849 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10850 sprintf() in line 1267.
10852 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10853 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10856 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10857 Changes to aslink (All the changes are marked with 'JCF'):
10859 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10862 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10863 area BSEG. Also moves, if possible, the DATA area down into the internal
10864 ram so more space is available.
10866 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10869 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10870 not bytes. Function summary() which creates a memory usage summary
10871 file with extension .mem. Reports of overlaping stack and small stack
10872 size. If the space for the stack is less than 16 bytes aslink trows a
10875 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10876 the 8051. Option 'y' for memory summary output file.
10878 Changes to sdcc (All the changes are marked with 'JCF'):
10880 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10882 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10883 overlaying area for it (uses RegBankUsed[4]).
10885 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10886 bank zero as used by default. By default aslink locates the stack
10887 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10888 the creation of the .mem file. Delegates the allocation of data area
10889 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10890 the begining of the stack area to aslink.
10892 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10893 glue() in SDCCglue.c creates an area for it.
10895 2002-09-03 Borut Razem <borut.razem AT siol.net>
10896 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10897 sdcc/src/pic/glue.c:
10898 introduced atexit() handler for teporay files removal in case of
10899 errors, assertions, ...
10901 2002-08-29 Borut Razem <borut.razem AT siol.net>
10902 * sdcc/support/cpp2/auto-host_vc_in.h:
10903 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10904 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10905 Maybe there is a similar problem with BORLANDC? It should be checked!
10907 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10908 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10909 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10910 was not executed, and the compiler (cl) launched a warning:
10911 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10913 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10914 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10916 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10917 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10919 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10920 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10921 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10922 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10923 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10924 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10925 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10926 - added Release configuration in VS projects
10927 - review of compiler an linker options
10928 - VC .exe files are generated in bin_vc directory, not to interfere
10929 with binaries generated from other projects (cygwin, mingw, bcc ...)
10931 * sdcc/src/yacc.dsp: added
10933 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10934 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10935 and insert the version number definitions from .version
10937 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10939 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10940 added - genarate auto-host.h using auto-host_vc_in.h as template
10943 removed from CVS, generated automatically
10945 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10946 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10948 2002-08-11 Borut Razem <borut.razem AT siol.net>
10949 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10951 2002-08-10 Borut Razem <borut.razem AT siol.net>
10952 * src/SDCCmain.c (main):
10953 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10954 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10955 The consequence was that some temporary files were not removed.
10958 unification of code in functions tempfilename() and tempfile():
10959 function tempnam() is defined in Visual Studio 6.0 and .NET
10961 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10963 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10964 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10965 - removed compiler command line option /WX: Treats all warnings as errors
10966 - update a list of source files, included into the project
10968 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10969 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10970 changed project type to Generic Project so that can be correcly converted to VS.NET project
10972 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10974 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10976 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10978 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10979 added return 0 statements after assert() to make compiler happy
10981 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10982 added newline in the def file to keep MSC compiler satisfied
10984 * sdcc/src/z80/gen.c:
10985 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10986 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10987 - solved MSC error in function aopDump()
10989 * sdcc_vc.h: define PREFIX as "\\sdcc"
10991 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10992 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10995 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10996 - Rewrote the register banking algorithm.
10997 - Added pCode live-range analysis to registers (for now, only non-used and
10998 singly-used registers optimized away)
11000 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11002 * 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.

11027 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11029 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11031 2002-03-28 Johan Knol <johan AT balder>
11033 * src/SDCCval.c: fixed bug #532436
11035 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11037 Added "char *Processor" field to the port structure.
11040 Added -p option. Allows port dependent processor to be specified.
11043 Initialized the new field char *Processor field to NULL in all ports
11046 Compiler generated registers for interrupt context saving
11047 were not getting allocated.
11049 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11052 Fixed left shift. Will promote the left side of a left shift
11053 if a) left shifting more than size of operand or b) when assigned
11054 to something size > size of left side
11056 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11060 analysis is restructured. ...
11062 * src/pic/device.h:
11065 * src/pic/device.c:
11066 Added. device.c is a PIC port hack to accomodate variations
11069 2002-03-13 Michael Hope <michaelh AT vroom>
11071 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11073 2002-03-04 johanknol <johanknol AT manik>
11075 * /src/SDCCval.c: fixed
11077 const unsigned char arr[][2] = { { 0, 1 } };

11164 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11166 * sdcc/src/SDCCloop.c:
11167 Previous fix was not good. basic blocks that have "break" or "return" are
11168 not really partof a loop , but live ranges used in these blocks should
11169 be live thru the entire loop, so set partOfLoop but don't add them to
11172 2002-02-21 <johan AT FRIJA>
11174 * src/SDCCcse.c: fixed bug #514308
11176 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11179 Fixed BUG #519583. If a conditional block ended in a return/break
11180 statement inside a loop, it was not being considered part of the loop.
11182 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11184 2002-02-10 Karl Bongers <karl AT turbobit.com>

11195 for use as a multiple module SDCDB test case.
11197 * sim/ucsim/cmd.src/cmdset.cc:
11198 Took out debug printfs in ucsim "next" command.
11200 * sim/ucsim/xa.src:
11201 Karl and Johan start ucsim XA support. Most dissassembly working,
11202 about 75% emulation done(plenty of work remaining).
11204 * sim/ucsim/z80.src:
11205 Add Z80 support to ucsim, add test-ucz80 regression test,
11206 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11207 Notice z80 compiler fails on examples/test3.c/crc code.
11209 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

11224 1) handle multiple send & receives from register bank1
11225 2) ralloc can now allocate DPTR1 to some liveRanges
11227 * src/SDCCsymt.c, src/SDCCsymt.h:
11228 changes to handle multiple sends & receives
11230 * src/SDCCptropt.h:
11231 added some pointer arithmetic optimization
11233 * src/SDCCptropt.c:

11240 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
11241 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
11242 set preprocessor defines (depending on options)
11244 * src/SDCCicode.c, src/SDCCicode.h:
11245 changes made to handle multiple sends & receives
