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

1297 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1298 call to allocReg, not by manually allocating a new one,
1299 (pic16_assignRegisters): now before going through the register
1300 allocating functions mark all registers as free. This eliminates some
1301 side effects resulting from peephole parser done earlier in the backbone

1353 2006-03-06 Borut Razem <borut.razem AT siol.net>
1355 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1356 made the linker quiet
1358 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1360 * src/pic16/gen.c (genPcall): fixed bug #1443644
1361 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1362 which dumps before the function entry point a data byte which represents
1363 the number of the local variables used by the specified function, added
1364 'xinst' for initial support for Extended Instruction Support,
1365 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1366 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1367 port->fun_prefix anymore (may change later),
1368 (genFunction, genEndFunction): do not store/restore local registers for
1369 _main (this should take care the --main-return command line option in
1371 (genOr): removed some legacy pic-port instructions,
1372 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1373 performing operations with SFR's causes data to be written more than
1374 once to each SFR. Perhaps SFRs should be handled in special cases...
1375 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1377 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1378 into account for stack starting position,
1379 (struct OPTIONS pic16_optionsTable): added command line argument
1380 --extended or -y for Extended Instruction Support,
1381 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1382 (deassignLRs): *** perhaps the most important change, old 'for' code
1383 (commented out for reference), didn't account for some registers which
1384 were left marked 'not free' after a pointer operation. The change
1385 reduces register usage a lot in some cases

3658 * src/SDCCglobal.h (struct options),
3660 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3661 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3662 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3663 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3664 always available in leading double underscore form. The C99 support is
3665 mostly missing, but it's a start.
3666 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3667 reserved identifier "__data".

3745 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3747 * device/lib/printf_large.c: removed inline assembly for portability and
3748 readability. Use printf_fast if speed or size are more important.
3749 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3750 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3752 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3754 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3755 prevent compiler warning
3757 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3759 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3760 moved to level 0 and declared as static. Also they are explicit
3761 placed in access bank. This was necessery because some times they
3762 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3763 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3764 optimizations. Currently only compare to unsigned char is implemented,
3765 * src/pic16/gen.c: added fReturnIdx array,
3766 * (struct resolvedIfx) is moved to gen.h and made public,
3767 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3768 * (aopForSym): added an optimization to directly store in stack of
3769 the operand of a SEND iCode,
3770 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3771 but as registers instead (AOP_REG) using the fReturnIdx array,
3772 * (pic16_freeAsmop): remove the freed register from the
3773 _G.sregsAlloc field,
3774 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3775 a compare of 'WREG',
3776 * (pic16_popGetTempRegCond): changed function prototype, now
3777 function takes also a bitVector argument v which holds the current
3778 set of registers that are allocated for stack access by aopForSym,
3779 registers allocated in aopForSym for accessing stack symbols are not
3780 any more part of the functions usedRegs field,
3781 * (genCall): some times aopOp is called for a stack variable to be
3782 send, aopForSym might perform the push, if this is true make sure
3783 that genCall doesn't push the variable twice by testing _G.resDirect,
3784 * (genFunction): changed testing for unspecified interrupt number
3785 from 256 to INTNO_UNSPEC,
3786 * modified selection scheme of frame pointer generation. Previously
3787 if function did use local registers a frame pointer was generated,
3788 now a frame pointer is generated only if function has arguments
3789 (that need PLUSW2 register access), or has stack arguments, or the
3790 compiler is not instructed to omit the frame pointer,
3791 * (genEndFunction): before restoring local registers that were saved
3792 in the function preamble, also restore the registers that *might*
3793 have been allocated for stack access,
3794 * (genRet): removed some old comments,
3795 * (genCmp, the active (RN's) version): added a call to the
3796 pic16_genCmp_special function to perform the compare with a more
3797 robust and optimized way,
3798 * (genInline): a feature has been added in inline code generation,
3799 which allows a wildcard variable substitution when writing inline
3800 assembly. Code is incomplete and experimental therefore undocumented,
3801 * (genCast): changed order of aopOp for result and right to allow
3802 aopForSym to directly load the result if possible,
3803 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3804 perform an optimized compare on some selected special occasions,
3805 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3806 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3807 generate an IVT any more,
3808 * src/pic16/main.c (pic16_optionsTable): added command line option
3810 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3811 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3813 * src/pic16/NOTES: Raphael Neider added in list of active developers
3814 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3815 jumptable_end to prevent bug #,
3816 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3817 inCond and outCond fields,
3818 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3819 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3820 turn off register spilling,
3821 * (packRegsForOneUse): synced with other ports' versions although it
3822 is not used currently,
3823 * (pic16_packRegisters): added an optimization while reading
3824 structure bitfields, some registers may be saved (malloc code is
3825 decreased by 80 bytes)
3827 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3829 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3830 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3831 this can be optimized more?
3833 2005-03-10 Raphael Neider <rneider AT web.de>
3835 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3836 genNearPointerGet): (hopefully) fixed access to bitfields via
3837 pointers (p->bitN = x; and x = p->bitN; failed)
3839 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3882 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3883 to keep the correct label reference count when adding/removing references

4471 Adding support for replacing ljmps with sjmps in jumptables
4472 generated for switch statements. For now you need to set the
4473 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4474 Now 4 algorithms for mcs51 jumptable generation are used:
4475 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4476 addresses loaded pc-relative for up to 112 cases and stack-pushing
4477 target addresses loaded with offset from dptr for up to 256 cases.

4507 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4509 * added libc directory. The current version of LibC contains string
4510 functions, ctype functions and macros and some functions of the
4511 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4512 be extensively tested in the future. Standard disclaimer here.
4513 Library is not automatically build yet. But one can build it by
4514 invoking 'make' inside the libc directory.

4524 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4525 * (pic16_storeForReturn): optimized return of 0,
4526 * (genCmp): experimental code for new genCmp which uses PIC18's
4527 special compare&skip instructions. Initial tests fail some times
4528 with variables grater than 1 byte in size, so new code is disabled,
4529 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4531 * (genCast): began a fix to optimize the casting of a bit to another
4532 bit, now assigning a bitfield to another bitfield will fail, sorry,
4533 * src/pic16/main.c: disabled the use of lr-support feature,
4534 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4540 * (isBankInstruction): modified to return 0 for no banking instruction,
4541 and 1 for banking instruction,
4542 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4543 caused stop processing pCodes after a inline assembly block,
4544 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4545 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4546 registers when it shouldn't,
4547 * src/pic16/ralloc.c (allocReg): add preliminary support for
4548 supporting a limited set of temporary registers,
4550 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4552 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4553 genDataPointerSet): ensure assignments always copy in MSB to LSB
4555 (loadRegFromAop): recognize CLRH optimization,
4556 (genFunction): optimize RECEIVE iCodes in reentrant functions
4558 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4560 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7558 loaded with the linker search paths (-L arguments) and the libraries
7559 to be linked with the current source (-l arguments). Changes
7560 currently will affect only the pic16 port.
7561 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7562 include path the port specific paths and port specific libraries,
7563 * gplink command now contains the $3 argument,
7564 * src/pic16/device.h,
7565 * src/pic16/device.c,: structure PIC_device is made public and
7566 renamed to PIC16_device, the same for variable Pics which is renamed

7581 Documenting changes from previous commits.
7582 * configure.in (version 1.56),
7583 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7584 when generating output files to configure the pic16 library,
7585 but now I've commented it out, since gputils aren't installed in the
7586 SF compile farm, so library won't compile
7588 * device/lib/Makefile.in (version 1.56): initially I've added in
7589 target 'all' the prerequestive 'model-pic16' so it compiled the
7590 pic16 library, but now I've commented it out for the same reasons
7592 * added targets 'model-pic16' and 'objects-pic16' to compile the
7594 * added target 'port-specific-objects-pic16' to handle the
7595 generated libraries and copy them into the build/ directory
7596 * added target 'clean-intermediate-pic16' to clean intermediate
7597 files into pic16 directory
7598 * in target 'installdirs' added line to create directory pic16 in

7901 * added files genutils.c and genutils.h which contain gen*
7902 debugged and optimised functions extracted from gen.c
7904 * glue.c: added variable 'externs' which holds extern symbols,
7905 pic16emitRegularMap: is modified to properly handle relocatable
7906 symbols under the new scheme,
7907 pic16createInterruptVect: is modified
7908 pic16printPublics: is modified to emit 'global' assembler directives,
7909 added pic16_printExterns to print extern symbols,
7910 pic16glue: initializes stack/frame pointer in the beginning of
7911 the assembly output. Temporary hack, will be corrected later,
7912 because gplink yet does not support stack and SDCC does not
7913 yet support a type of crt0.o object to create the final binary.
7915 * Removed many lines that contain 8051 legacy code.
7916 * The code is finally placed under a 'code' directive.
7917 * Added port specific options.
7919 * _process_pragma: simplified since now we do not need *special*
7920 include file to define SFR registers. But a separate header
7921 will be needed. This will be developed later.
7922 * _pic16_parseOptions: added, parses port specific options:
7923 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7924 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7925 --preplace-udata-with=
7927 * _pic16_setDefaultOptions: modified to initialize section names,
7928 but hack is temporarly out of order since it needs improvement.
7929 * _pic16_genAssemblerPreamble: configuration words are emitted by
7930 their address instead of their name. This part is incomplete and
7931 supports only the 18Fxx2 devices. Other devices will emit an error
7932 during assembly since they do not contain the same set of config
7934 * _pic16_genIVT: is modified,
7936 * pcode.c: added definitions for some hardware registers that are needed
7938 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7939 All PCI entries are updated. Now LFSR is supported.
7940 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7941 * added pic16_newpCodeOpLit2 to support instructions with
7942 two literal arguments
7943 * pic16_pCode2str: corrected code that emits assembler instructions
7944 with two literal operands and those that have an access bit modifier
7945 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7946 this fixes a bug which caused some labels to be lost, when an
7947 assembler directive was added, i.e. banksel,
7948 * pic16_FixRegisterBanking: improved logic that causes the insertion
7950 * InlineFunction: functions that are called once, are not any more
7951 inlined. This can be a port option in the future,
7953 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7955 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7956 hold the corresponding uninitialized symbols,
7957 * pic16_allocProcessorRegister: registers have explicit marked the
7959 * pic16_allocInternalRegister: registers are explicit marked as
7961 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7962 processing list, so bit registers were lost,
7965 * ralloc.h: added field 'accessBank' and original symbol operand
7966 in register definition,
7967 * removed the field isMapped from register definition,
7969 ** Several functions have been removed from various sources:
7970 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7971 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7972 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7973 pic16_assignRelocatableRegisters
7975 ** others have been introduced:
7976 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7977 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7979 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7981 * support/scripts/inc2h.pl: changed definition of BIT_AT
7982 to emit 'sbit at' instead of 'bit at'. This was a request.
7984 PIC16 port related preliminary changes:
7985 * gen.c: prefixed function popRegFromString with
7986 pic16_ and all references to it corrected
7987 * pcode.c: all pic16_pc_* hardware registers prefixed
7988 with underscore (_),
7989 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7990 * ralloc.c: newReg(): when register is REG_SFR then
7991 set address to rIdx,
7992 pic16_allocProcessorRegister(): marks register wasUsed=0
7993 pic16_writeUsedRegs(): added a call to assign processor
7994 registers via pic16_assignFixedRegisters
7996 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7998 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7999 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8000 variables in unused register banks. Also the SSEG is placed
8001 wherever there is enough space for it, and IDATA can be anywhere
8002 in internal RAM. For now compile using -Wl-Y[stack_size].
8003 The mem file is different for this option as well, since it
8004 makes no sense of talking about DSEG lenght.
8006 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8008 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8009 in certain cases, e.g. when ROM assignment, patch provided
8010 from Albert den Haan.

8251 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8253 * src/SDCCast.c (decorateType): disabled a transformation I added in
8254 revision 1.188 (access to fields of a structure at an absolute address);
8255 it breaks with bitfields, extern declarations, and gcse analysis.
8256 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8257 could be assigned through a pointer, so don't complain.
8258 * src/SDCCast.c (astErrors),
8260 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8360 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8362 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8363 uninitialized variables) for the mcs51. Set environment variable

9014 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9015 fetching of the pointer
9016 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9017 copied from genNearPointerSet()
9018 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9019 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9035 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9036 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9037 type for bits was changed. It resulted in bit variables becoming
9038 global, which is not permitted in PIC 14 assembly output.
9040 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9042 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9055 A few small changes that speed up the peephole optimizer.
9059 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9061 Try to make the peephole optimizer smarter by maintaining
9062 an association between the assembly source code and the
9063 iCodes that originated them. Put this information to use
9064 with a new peephole rule condition "notVolatile" so that
9065 the rules can be aggressive yet still safe.
9070 * src/mcs51/peeph.def
9072 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9076 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9077 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9078 if the left or right operand symbols have the accuse flag set.
9080 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9082 Changed the type of the result of the ! (NOT) operator to char;
9083 previously it returned the same type as the source. This allows
9084 us to eliminate all the genFloatNot functions (all of its target
9085 implementations were very buggy) since !float can use the same
9088 * src/SDCCicode.c (ast2iCode): ! returns char

9097 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9098 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9099 during interrupts. Ensure WSAVE is located at a shared bank address.
9100 2. Fixed page selection in some places
9101 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9102 the registers name strings.
9103 4. Fixed "signed / unsigned compare" compiler warnings.
9104 5. The PIC port manages its own allocation of the general purpose
9105 registers, but makes no attempt to reuse them. As a result when
9106 compiling it soon runs out of general purpose registers. Some
9107 additional code was added to the files pcode.c and device.c to walk
9108 through the function call tree and rename the registers so that they
9118 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9119 genPlus() & genMinus() when the result is the same as left or right

9125 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9127 Made bitfield a distinct type from bit so that bitfields
9128 convert as per ANSI C and bits retain their traditional
9129 boolean style behaviour. Implemented bitfield support in
9137 * src/ds390/gen.c: bit v bitfield split
9138 * src/z80/gen.c: New support for bitfields
9139 * support/regression/tests/bitfields.c: reenabled z80,
9142 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9144 Rules 246.x, 247.x relate to bitfields, the others speed up
9145 access to xdata mapped I/O devices.
9147 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9149 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9151 Cleaned up genPackBits and genUnpackBits and added two helper
9152 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9153 for literal assignments in genPackBits (thanks to Frieder for
9159 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9161 Fixed bug #748310 (pointer to function type mishandled when the
9162 function name is omitted). Also fixed a SIGSEGV when a function
9163 attribute (reentrant, etc) is used on a non-function or on a
9164 function but misplaced before the parameter list.
9166 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9168 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9169 * support/Util/SDCCerr.h,
9170 * support/Util/SDCCerr.c: Added func attr misuse error msg

9191 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9193 Made the constant following the "interrupt" keyword optional. If
9194 omitted, the function will not automatically be given an entry
9195 in the interrupt vector table (similar to #pragma NOIV, but
9196 less syntacticly kludgy). The interrupt number is also now
9197 range checked. Also fixed a bug in the high order bit example

9208 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9210 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9211 * src/SDCCicode.c (operandOperation): rewritten some ops
9212 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9213 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9215 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9216 be re-activated by defining REDUCE_LITERALS)
9217 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9218 unsigned, but are signed by default
9219 * src/SDCCval.c (constVal): rearranged
9220 * src/SDCCval.c (valMod): preliminary fix
9221 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9263 constants are unsigned; added recognition of "u" flag for unsigned
9264 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9265 * src/SDCCval.c (valDiv, valMod): fixed signdness
9266 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9267 signedness of modulo, left and right shift

9726 * src/SDCCmain.c: linkOptions is changed to set *,
9727 added if/endif conditional macros to remove options help
9728 messages from optionsTable when a port is not configured, added
9729 support for the PIc16 port in the ports table, when executing
9730 the compiler with no port specified on command line, a default
9731 port is selected with the new macro DEFAULT_PORT which is
9732 defined in port.h, in setDefaultOptions() linkOptions is removed
9733 from initialization assignment, since now it is a set,
9734 parseCmdLine uses setParseWithComma for linkOptions, in
9735 linkEdit() linkOptions are accessed with new function indexSet()
9736 which returns the i'th item of a set variable. See SDCCset.c, in
9737 linkEdit() when calling buildCmdLine(), added linkOptions as
9738 last argument. Now users can pass arguments to gplink via the
9739 -Wl option, main() uses pic16glue() to glue up pic16 programs

9751 * src/pic16/glue.c: commented out some error producing lines
9752 * src/pic16/main.c: __config directives are commented out to stop
9753 gpasm complaining and test the linkage with gplink, _linkCmd and
9754 _asmCmd changed to be more gplink and gpasm friendly
9755 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9756 produced an error when parsed, peep rule 12 is added to utilize
9757 movff, but it is commented out since the pCode does not support
9758 yet a command with 2 address arguments
9760 2003-05-18 <johan AT balder>
9762 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9787 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9789 2003-05-11 Borut Razem <borut.razem AT siol.net>
9791 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9792 the path of bin directory, so that PATH is the only env. variable, which has to be set
9793 in case of standard installation.
9794 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10789 * src/pic/ralloc.c: outcommented unused variable to remove warnings
10791 2003-01-06 <karl AT turbobit.com>
10792 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
10795 2003-01-06 <johan AT balder>
10797 * src/SDCCicode.c: fixed array add
10799 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10800 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10801 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10803 2003-01-04 <johan AT balder>
10805 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10807 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10808 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10810 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10811 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10812 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10814 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10815 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10817 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10818 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10820 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10821 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10823 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10825 * in /sdcc/as/mcs51/ changed these files in order to create an
10826 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10827 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10828 following files to include the previous two files: aslink.dsp,
10829 Makefile.aslink, Makefile.bcc, and Makefile.in.
10831 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10832 .adb instead of .cdb
10834 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10836 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10837 value from option --iram-size.
10839 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10841 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10844 2002-09-18 <wiml AT hhhh.org>
10846 * SDCClrange.h: exposed setFromRange() and setToRange()
10847 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10848 packRegsForAccUse() (bug 542397)
10849 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10850 multiple times and emitting the fetch operations more than once
10851 added aopGetUsesAcc() function to allow binary operators to
10852 fetch their operands in the correct order; made genMinus() emit
10853 compact code for X = LITERAL - Y
10855 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10856 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10857 sprintf() in line 1267.
10859 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10860 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10863 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10864 Changes to aslink (All the changes are marked with 'JCF'):
10866 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10869 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10870 area BSEG. Also moves, if possible, the DATA area down into the internal
10871 ram so more space is available.
10873 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10876 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10877 not bytes. Function summary() which creates a memory usage summary
10878 file with extension .mem. Reports of overlaping stack and small stack
10879 size. If the space for the stack is less than 16 bytes aslink trows a
10882 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10883 the 8051. Option 'y' for memory summary output file.
10885 Changes to sdcc (All the changes are marked with 'JCF'):
10887 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10889 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10890 overlaying area for it (uses RegBankUsed[4]).
10892 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10893 bank zero as used by default. By default aslink locates the stack
10894 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10895 the creation of the .mem file. Delegates the allocation of data area
10896 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10897 the begining of the stack area to aslink.
10899 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10900 glue() in SDCCglue.c creates an area for it.
10902 2002-09-03 Borut Razem <borut.razem AT siol.net>
10903 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10904 sdcc/src/pic/glue.c:
10905 introduced atexit() handler for teporay files removal in case of
10906 errors, assertions, ...
10908 2002-08-29 Borut Razem <borut.razem AT siol.net>
10909 * sdcc/support/cpp2/auto-host_vc_in.h:
10910 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10911 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10912 Maybe there is a similar problem with BORLANDC? It should be checked!
10914 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10915 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10916 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10917 was not executed, and the compiler (cl) launched a warning:
10918 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10920 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10921 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10923 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10924 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10926 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10927 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10928 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10929 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10930 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10931 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10932 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10933 - added Release configuration in VS projects
10934 - review of compiler an linker options
10935 - VC .exe files are generated in bin_vc directory, not to interfere
10936 with binaries generated from other projects (cygwin, mingw, bcc ...)
10938 * sdcc/src/yacc.dsp: added
10940 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10941 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10942 and insert the version number definitions from .version
10944 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10946 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10947 added - genarate auto-host.h using auto-host_vc_in.h as template
10950 removed from CVS, generated automatically
10952 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10953 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10955 2002-08-11 Borut Razem <borut.razem AT siol.net>
10956 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10958 2002-08-10 Borut Razem <borut.razem AT siol.net>
10959 * src/SDCCmain.c (main):
10960 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10961 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10962 The consequence was that some temporary files were not removed.
10965 unification of code in functions tempfilename() and tempfile():
10966 function tempnam() is defined in Visual Studio 6.0 and .NET
10968 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10970 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10971 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10972 - removed compiler command line option /WX: Treats all warnings as errors
10973 - update a list of source files, included into the project
10975 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10976 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10977 changed project type to Generic Project so that can be correcly converted to VS.NET project
10979 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10981 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10983 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10985 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10986 added return 0 statements after assert() to make compiler happy
10988 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10989 added newline in the def file to keep MSC compiler satisfied
10991 * sdcc/src/z80/gen.c:
10992 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10993 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10994 - solved MSC error in function aopDump()
10996 * sdcc_vc.h: define PREFIX as "\\sdcc"
10998 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10999 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11034 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11036 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11038 2002-03-28 Johan Knol <johan AT balder>
11040 * src/SDCCval.c: fixed bug #532436
11042 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11044 Added "char *Processor" field to the port structure.
11047 Added -p option. Allows port dependent processor to be specified.
11050 Initialized the new field char *Processor field to NULL in all ports
11053 Compiler generated registers for interrupt context saving
11054 were not getting allocated.
11056 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11059 Fixed left shift. Will promote the left side of a left shift
11060 if a) left shifting more than size of operand or b) when assigned
11061 to something size > size of left side
11063 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11065 tons of changes. Register allocation has been
11066 rewritten. Added customization for the various PICs. Flow
11067 analysis is restructured. ...
11069 * src/pic/device.h:
11072 * src/pic/device.c:
11073 Added. device.c is a PIC port hack to accomodate variations
11076 2002-03-13 Michael Hope <michaelh AT vroom>
11078 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11080 2002-03-04 johanknol <johanknol AT manik>
11082 * /src/SDCCval.c: fixed
11084 const unsigned char arr[][2] = { { 0, 1 } };

11171 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11173 * sdcc/src/SDCCloop.c:
11174 Previous fix was not good. basic blocks that have "break" or "return" are
11175 not really partof a loop , but live ranges used in these blocks should
11176 be live thru the entire loop, so set partOfLoop but don't add them to
11179 2002-02-21 <johan AT FRIJA>
11181 * src/SDCCcse.c: fixed bug #514308
11183 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11186 Fixed BUG #519583. If a conditional block ended in a return/break
11187 statement inside a loop, it was not being considered part of the loop.
11189 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11191 2002-02-10 Karl Bongers <karl AT turbobit.com>

11197 * device/examples/test2.c:
11198 Fix bug, "red" variable not being initialized(compiler complained).
11200 * device/examples/Makefile, examples/test3.c:
11201 Add Makefile in device/examples folder, compiles test3.c
11202 for use as a multiple module SDCDB test case.
11204 * sim/ucsim/cmd.src/cmdset.cc:
11205 Took out debug printfs in ucsim "next" command.
11207 * sim/ucsim/xa.src:
11208 Karl and Johan start ucsim XA support. Most dissassembly working,
11209 about 75% emulation done(plenty of work remaining).
11211 * sim/ucsim/z80.src:
11212 Add Z80 support to ucsim, add test-ucz80 regression test,
11213 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11214 Notice z80 compiler fails on examples/test3.c/crc code.
11216 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

11230 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11231 1) handle multiple send & receives from register bank1
11232 2) ralloc can now allocate DPTR1 to some liveRanges
11234 * src/SDCCsymt.c, src/SDCCsymt.h:
11235 changes to handle multiple sends & receives
11237 * src/SDCCptropt.h:
11238 added some pointer arithmetic optimization
11240 * src/SDCCptropt.c:

11242 called from anywhere (will get this working shortly)
11244 * src/SDCCopt.c: fixed for multiple sends & receives
11247 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
11248 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
11249 set preprocessor defines (depending on options)
11251 * src/SDCCicode.c, src/SDCCicode.h:
11252 changes made to handle multiple sends & receives
11255 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
