974 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
976 Enabled VPATH feature: changed nearly all Makefiles (149 files).
977 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
979 One basic decision: e.g. src/clean.mk includes further files. In order
980 to make this work there are two solutions:
981 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
982 run configure on them. This way they can use
983 'include $(srcdir)/port-clean.mk'
984 - always include clean.mk by the Makefile at the same level. To avoid
985 that `make clean` tries to include and build Makefile.dep the
986 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
987 implemented, because now even `make uninstall` doesn't create
988 Makefile.in. clean.mk could be eliminated by pasting it in
991 * debugger/mcs51/Makefile.in: build own objects from library sources
992 (SLIB, SDCC) in current directory
994 * configure, configure.in: renamed --disable-device-lib-build in
995 --disable-device-lib; added --enable-doc, the required tools are
996 searched by configure; added result message; the toolchain for the
997 belonging ports are now only built, if the port is enabled.
999 * support/regression/*: all output is written in directory gen, because
1000 the fwk and ports directories don't livet in the build tree using vpath
1002 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1003 --disable-device-lib, added --enable-doc, added section VPATH
1005 * sim/ucsim/configure.in,
1006 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1007 z80 are enabled by default
1009 2006-04-24 Raphael Neider <rneider AT web.de>
1011 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1012 to config word, "pic14_"-prefixed some extern functions
1013 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1014 config word has been found
1015 * src/pic/device.h: added prototypes
1016 * src/pic/pcode.c: added "pic14_"-prefix where needed
1017 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1019 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1031 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1032 registers that have not been assigned proper liveranges,
1033 fixes #1469504 and #1474602,
1034 (pCodeRegOptimizeRegUsage): fixed typo in comment

1038 * device/examples/main8051.c: deleted - it was removed from CVS

1307 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1308 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1324 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1325 call to allocReg, not by manually allocating a new one,
1326 (pic16_assignRegisters): now before going through the register
1327 allocating functions mark all registers as free. This eliminates some
1328 side effects resulting from peephole parser done earlier in the backbone
1330 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1378 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1380 2006-03-06 Borut Razem <borut.razem AT siol.net>
1382 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1383 made the linker quiet
1385 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1387 * src/pic16/gen.c (genPcall): fixed bug #1443644
1388 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1389 which dumps before the function entry point a data byte which represents
1390 the number of the local variables used by the specified function, added
1391 'xinst' for initial support for Extended Instruction Support,
1392 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1393 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1394 port->fun_prefix anymore (may change later),

1407 --extended or -y for Extended Instruction Support,
1408 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1409 (deassignLRs): *** perhaps the most important change, old 'for' code
1410 (commented out for reference), didn't account for some registers which
1411 were left marked 'not free' after a pointer operation. The change
1412 reduces register usage a lot in some cases

3687 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3688 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3689 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3690 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3691 always available in leading double underscore form. The C99 support is
3692 mostly missing, but it's a start.
3693 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3694 reserved identifier "__data".
3696 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3772 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3774 * device/lib/printf_large.c: removed inline assembly for portability and
3775 readability. Use printf_fast if speed or size are more important.
3776 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3777 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3779 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3781 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3782 prevent compiler warning
3784 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3786 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3787 moved to level 0 and declared as static. Also they are explicit
3788 placed in access bank. This was necessery because some times they
3789 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3790 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3791 optimizations. Currently only compare to unsigned char is implemented,
3792 * src/pic16/gen.c: added fReturnIdx array,
3793 * (struct resolvedIfx) is moved to gen.h and made public,
3794 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3795 * (aopForSym): added an optimization to directly store in stack of
3796 the operand of a SEND iCode,
3797 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3798 but as registers instead (AOP_REG) using the fReturnIdx array,
3799 * (pic16_freeAsmop): remove the freed register from the
3800 _G.sregsAlloc field,
3801 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3802 a compare of 'WREG',
3803 * (pic16_popGetTempRegCond): changed function prototype, now
3804 function takes also a bitVector argument v which holds the current
3805 set of registers that are allocated for stack access by aopForSym,
3806 registers allocated in aopForSym for accessing stack symbols are not
3807 any more part of the functions usedRegs field,
3808 * (genCall): some times aopOp is called for a stack variable to be
3809 send, aopForSym might perform the push, if this is true make sure
3810 that genCall doesn't push the variable twice by testing _G.resDirect,
3811 * (genFunction): changed testing for unspecified interrupt number
3812 from 256 to INTNO_UNSPEC,
3813 * modified selection scheme of frame pointer generation. Previously
3814 if function did use local registers a frame pointer was generated,
3815 now a frame pointer is generated only if function has arguments
3816 (that need PLUSW2 register access), or has stack arguments, or the
3817 compiler is not instructed to omit the frame pointer,
3818 * (genEndFunction): before restoring local registers that were saved
3819 in the function preamble, also restore the registers that *might*
3820 have been allocated for stack access,
3821 * (genRet): removed some old comments,
3822 * (genCmp, the active (RN's) version): added a call to the
3823 pic16_genCmp_special function to perform the compare with a more
3824 robust and optimized way,
3825 * (genInline): a feature has been added in inline code generation,
3826 which allows a wildcard variable substitution when writing inline
3827 assembly. Code is incomplete and experimental therefore undocumented,
3828 * (genCast): changed order of aopOp for result and right to allow
3829 aopForSym to directly load the result if possible,
3830 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3831 perform an optimized compare on some selected special occasions,
3832 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3833 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3834 generate an IVT any more,
3835 * src/pic16/main.c (pic16_optionsTable): added command line option
3837 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3838 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3840 * src/pic16/NOTES: Raphael Neider added in list of active developers
3841 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3842 jumptable_end to prevent bug #,
3843 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3844 inCond and outCond fields,
3845 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3846 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3847 turn off register spilling,
3848 * (packRegsForOneUse): synced with other ports' versions although it
3849 is not used currently,
3850 * (pic16_packRegisters): added an optimization while reading
3851 structure bitfields, some registers may be saved (malloc code is
3852 decreased by 80 bytes)
3854 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3856 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3857 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3858 this can be optimized more?
3860 2005-03-10 Raphael Neider <rneider AT web.de>
3862 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3863 genNearPointerGet): (hopefully) fixed access to bitfields via
3864 pointers (p->bitN = x; and x = p->bitN; failed)
3866 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3868 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3880 * support/regression/tests/critical.c: check bug 1144613
3882 2005-03-02 Raphael Neider <rneider AT web.de>
3884 * src/pic16/gen.c (genRightShiftLiteral): fixed bug #1154256
3886 2005-02-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4498 Adding support for replacing ljmps with sjmps in jumptables
4499 generated for switch statements. For now you need to set the
4500 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4501 Now 4 algorithms for mcs51 jumptable generation are used:
4502 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4503 addresses loaded pc-relative for up to 112 cases and stack-pushing
4504 target addresses loaded with offset from dptr for up to 256 cases.

4534 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4536 * added libc directory. The current version of LibC contains string
4537 functions, ctype functions and macros and some functions of the
4538 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4539 be extensively tested in the future. Standard disclaimer here.
4540 Library is not automatically build yet. But one can build it by
4541 invoking 'make' inside the libc directory.

4552 * (pic16_storeForReturn): optimized return of 0,
4553 * (genCmp): experimental code for new genCmp which uses PIC18's
4554 special compare&skip instructions. Initial tests fail some times
4555 with variables grater than 1 byte in size, so new code is disabled,
4556 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4558 * (genCast): began a fix to optimize the casting of a bit to another
4559 bit, now assigning a bitfield to another bitfield will fail, sorry,

4568 and 1 for banking instruction,
4569 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4570 caused stop processing pCodes after a inline assembly block,
4571 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4572 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4573 registers when it shouldn't,
4574 * src/pic16/ralloc.c (allocReg): add preliminary support for
4575 supporting a limited set of temporary registers,
4577 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4579 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4580 genDataPointerSet): ensure assignments always copy in MSB to LSB
4582 (loadRegFromAop): recognize CLRH optimization,
4583 (genFunction): optimize RECEIVE iCodes in reentrant functions
4585 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4587 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7585 loaded with the linker search paths (-L arguments) and the libraries
7586 to be linked with the current source (-l arguments). Changes
7587 currently will affect only the pic16 port.
7588 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7589 include path the port specific paths and port specific libraries,
7590 * gplink command now contains the $3 argument,

7608 Documenting changes from previous commits.
7609 * configure.in (version 1.56),
7610 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7611 when generating output files to configure the pic16 library,
7612 but now I've commented it out, since gputils aren't installed in the
7613 SF compile farm, so library won't compile
7615 * device/lib/Makefile.in (version 1.56): initially I've added in
7616 target 'all' the prerequestive 'model-pic16' so it compiled the
7617 pic16 library, but now I've commented it out for the same reasons
7619 * added targets 'model-pic16' and 'objects-pic16' to compile the
7621 * added target 'port-specific-objects-pic16' to handle the
7622 generated libraries and copy them into the build/ directory
7623 * added target 'clean-intermediate-pic16' to clean intermediate
7624 files into pic16 directory
7625 * in target 'installdirs' added line to create directory pic16 in

7629 added lines to copy all header files to installation path,
7630 * in target 'installdirs' added line create directory for pic16
7631 headers in the installation path

7903 Bug reported from Jesus Calvino-Fraga
7905 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7907 * sdcc.spec: updated
7908 * device/include/Makefile.in: don't install CVS directories
7909 * device/lib/Makefile.in: added removal of CVS directories after install
7910 * doc/Makefile: fixed install, added local_icons
7911 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7912 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7913 * src/ds390/gen.c (genRightShift): fixed bug #870788
7914 * src/SDCCast.c (decorateType): fixed bug #870781
7916 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7918 PIC16 port related changes:
7919 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7920 added variable stackPos,
7922 * gen.c: genCall, assignResultValue: added support for
7923 pushing/retrieving function parameters to/from stack,
7924 genFunction,genEndFunction: setup stack frame for the
7926 genAddrOf: will be changed according to bug 863624
7928 * added files genutils.c and genutils.h which contain gen*
7929 debugged and optimised functions extracted from gen.c
7931 * glue.c: added variable 'externs' which holds extern symbols,
7932 pic16emitRegularMap: is modified to properly handle relocatable
7933 symbols under the new scheme,
7934 pic16createInterruptVect: is modified
7935 pic16printPublics: is modified to emit 'global' assembler directives,
7936 added pic16_printExterns to print extern symbols,
7937 pic16glue: initializes stack/frame pointer in the beginning of
7938 the assembly output. Temporary hack, will be corrected later,
7939 because gplink yet does not support stack and SDCC does not
7940 yet support a type of crt0.o object to create the final binary.
7942 * Removed many lines that contain 8051 legacy code.
7943 * The code is finally placed under a 'code' directive.
7944 * Added port specific options.
7946 * _process_pragma: simplified since now we do not need *special*
7947 include file to define SFR registers. But a separate header
7948 will be needed. This will be developed later.
7949 * _pic16_parseOptions: added, parses port specific options:
7950 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7951 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7952 --preplace-udata-with=
7954 * _pic16_setDefaultOptions: modified to initialize section names,
7955 but hack is temporarly out of order since it needs improvement.
7956 * _pic16_genAssemblerPreamble: configuration words are emitted by
7957 their address instead of their name. This part is incomplete and
7958 supports only the 18Fxx2 devices. Other devices will emit an error
7959 during assembly since they do not contain the same set of config
7961 * _pic16_genIVT: is modified,
7963 * pcode.c: added definitions for some hardware registers that are needed
7965 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7966 All PCI entries are updated. Now LFSR is supported.
7967 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7968 * added pic16_newpCodeOpLit2 to support instructions with
7969 two literal arguments
7970 * pic16_pCode2str: corrected code that emits assembler instructions
7971 with two literal operands and those that have an access bit modifier
7972 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7973 this fixes a bug which caused some labels to be lost, when an
7974 assembler directive was added, i.e. banksel,
7975 * pic16_FixRegisterBanking: improved logic that causes the insertion
7977 * InlineFunction: functions that are called once, are not any more
7978 inlined. This can be a port option in the future,
7980 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7982 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7983 hold the corresponding uninitialized symbols,
7984 * pic16_allocProcessorRegister: registers have explicit marked the
7986 * pic16_allocInternalRegister: registers are explicit marked as
7988 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7989 processing list, so bit registers were lost,
7992 * ralloc.h: added field 'accessBank' and original symbol operand
7993 in register definition,
7994 * removed the field isMapped from register definition,
7996 ** Several functions have been removed from various sources:
7997 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7998 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7999 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8000 pic16_assignRelocatableRegisters
8002 ** others have been introduced:
8003 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8004 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8006 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8008 * support/scripts/inc2h.pl: changed definition of BIT_AT
8009 to emit 'sbit at' instead of 'bit at'. This was a request.
8011 PIC16 port related preliminary changes:
8012 * gen.c: prefixed function popRegFromString with
8013 pic16_ and all references to it corrected
8014 * pcode.c: all pic16_pc_* hardware registers prefixed
8015 with underscore (_),
8016 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8017 * ralloc.c: newReg(): when register is REG_SFR then
8018 set address to rIdx,
8019 pic16_allocProcessorRegister(): marks register wasUsed=0
8020 pic16_writeUsedRegs(): added a call to assign processor
8021 registers via pic16_assignFixedRegisters
8023 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8025 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8026 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8027 variables in unused register banks. Also the SSEG is placed
8028 wherever there is enough space for it, and IDATA can be anywhere
8029 in internal RAM. For now compile using -Wl-Y[stack_size].
8030 The mem file is different for this option as well, since it
8031 makes no sense of talking about DSEG lenght.
8033 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8035 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8036 in certain cases, e.g. when ROM assignment, patch provided
8037 from Albert den Haan.
8039 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8278 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8280 * src/SDCCast.c (decorateType): disabled a transformation I added in
8281 revision 1.188 (access to fields of a structure at an absolute address);
8282 it breaks with bitfields, extern declarations, and gcse analysis.
8283 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8284 could be assigned through a pointer, so don't complain.
8285 * src/SDCCast.c (astErrors),
8287 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8925 support for standard C idiom of memory mapped variables; for
8926 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8927 to xdata int at 0x1234 tempvar = 1.
8928 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8929 provided by Akiya ISHIDA

8945 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8947 Fixed bug #621531 (const & volatile confusion in the type chain).
8948 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8949 refer to the const or volatile state of the pointer itself.

9014 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9015 pcoderegs.h, ralloc.c, ralloc.h
9016 * main.c: added top header and GPL license notice

9040 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9041 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9042 fetching of the pointer
9043 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9044 copied from genNearPointerSet()
9045 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9046 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9047 If they pop r0/r1 they must be called in the opposite order than aopOp().
9048 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9049 (resp. --stack-auto), prepared for --xstack

9060 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9062 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9063 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9064 type for bits was changed. It resulted in bit variables becoming
9065 global, which is not permitted in PIC 14 assembly output.
9067 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9069 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9082 A few small changes that speed up the peephole optimizer.
9086 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9088 Try to make the peephole optimizer smarter by maintaining
9089 an association between the assembly source code and the
9090 iCodes that originated them. Put this information to use
9091 with a new peephole rule condition "notVolatile" so that
9092 the rules can be aggressive yet still safe.
9097 * src/mcs51/peeph.def
9099 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9103 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9104 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9105 if the left or right operand symbols have the accuse flag set.
9107 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9109 Changed the type of the result of the ! (NOT) operator to char;
9110 previously it returned the same type as the source. This allows
9111 us to eliminate all the genFloatNot functions (all of its target
9112 implementations were very buggy) since !float can use the same

9124 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9125 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9126 during interrupts. Ensure WSAVE is located at a shared bank address.
9127 2. Fixed page selection in some places
9128 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9129 the registers name strings.
9130 4. Fixed "signed / unsigned compare" compiler warnings.
9131 5. The PIC port manages its own allocation of the general purpose
9132 registers, but makes no attempt to reuse them. As a result when
9133 compiling it soon runs out of general purpose registers. Some
9134 additional code was added to the files pcode.c and device.c to walk
9135 through the function call tree and rename the registers so that they
9145 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9146 genPlus() & genMinus() when the result is the same as left or right

9152 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9154 Made bitfield a distinct type from bit so that bitfields
9155 convert as per ANSI C and bits retain their traditional
9156 boolean style behaviour. Implemented bitfield support in
9164 * src/ds390/gen.c: bit v bitfield split
9165 * src/z80/gen.c: New support for bitfields
9166 * support/regression/tests/bitfields.c: reenabled z80,
9169 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9171 Rules 246.x, 247.x relate to bitfields, the others speed up
9172 access to xdata mapped I/O devices.
9174 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9176 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9178 Cleaned up genPackBits and genUnpackBits and added two helper
9179 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9180 for literal assignments in genPackBits (thanks to Frieder for
9186 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9188 Fixed bug #748310 (pointer to function type mishandled when the
9189 function name is omitted). Also fixed a SIGSEGV when a function
9190 attribute (reentrant, etc) is used on a non-function or on a
9191 function but misplaced before the parameter list.
9193 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9195 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9196 * support/Util/SDCCerr.h,
9197 * support/Util/SDCCerr.c: Added func attr misuse error msg

9218 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9220 Made the constant following the "interrupt" keyword optional. If
9221 omitted, the function will not automatically be given an entry
9222 in the interrupt vector table (similar to #pragma NOIV, but
9223 less syntacticly kludgy). The interrupt number is also now
9224 range checked. Also fixed a bug in the high order bit example

9238 * src/SDCCicode.c (operandOperation): rewritten some ops
9239 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9240 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9242 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9243 be re-activated by defining REDUCE_LITERALS)
9244 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9245 unsigned, but are signed by default
9246 * src/SDCCval.c (constVal): rearranged
9247 * src/SDCCval.c (valMod): preliminary fix
9248 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9754 added if/endif conditional macros to remove options help
9755 messages from optionsTable when a port is not configured, added
9756 support for the PIc16 port in the ports table, when executing
9757 the compiler with no port specified on command line, a default
9758 port is selected with the new macro DEFAULT_PORT which is
9759 defined in port.h, in setDefaultOptions() linkOptions is removed
9760 from initialization assignment, since now it is a set,
9761 parseCmdLine uses setParseWithComma for linkOptions, in
9762 linkEdit() linkOptions are accessed with new function indexSet()
9763 which returns the i'th item of a set variable. See SDCCset.c, in
9764 linkEdit() when calling buildCmdLine(), added linkOptions as
9765 last argument. Now users can pass arguments to gplink via the
9766 -Wl option, main() uses pic16glue() to glue up pic16 programs

9780 gpasm complaining and test the linkage with gplink, _linkCmd and
9781 _asmCmd changed to be more gplink and gpasm friendly
9782 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9783 produced an error when parsed, peep rule 12 is added to utilize
9784 movff, but it is commented out since the pCode does not support
9785 yet a command with 2 address arguments
9787 2003-05-18 <johan AT balder>
9789 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9816 2003-05-11 Borut Razem <borut.razem AT siol.net>
9818 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10811 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10812 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10813 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10814 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10815 * src/pic/pcode.c: outcommented unused variable to remove warnings

10822 2003-01-06 <johan AT balder>
10824 * src/SDCCicode.c: fixed array add
10826 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10827 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10828 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10830 2003-01-04 <johan AT balder>
10832 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10834 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10835 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10837 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10838 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10839 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10841 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10842 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10844 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10845 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10847 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10848 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10850 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10852 * in /sdcc/as/mcs51/ changed these files in order to create an
10853 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10854 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10855 following files to include the previous two files: aslink.dsp,
10856 Makefile.aslink, Makefile.bcc, and Makefile.in.
10858 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10859 .adb instead of .cdb
10861 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10863 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10864 value from option --iram-size.
10866 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10868 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10871 2002-09-18 <wiml AT hhhh.org>
10873 * SDCClrange.h: exposed setFromRange() and setToRange()
10874 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10875 packRegsForAccUse() (bug 542397)
10876 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10877 multiple times and emitting the fetch operations more than once
10878 added aopGetUsesAcc() function to allow binary operators to
10879 fetch their operands in the correct order; made genMinus() emit
10880 compact code for X = LITERAL - Y
10882 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10883 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10884 sprintf() in line 1267.
10886 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10887 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10890 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10891 Changes to aslink (All the changes are marked with 'JCF'):
10893 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10896 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10897 area BSEG. Also moves, if possible, the DATA area down into the internal
10898 ram so more space is available.
10900 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10903 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10904 not bytes. Function summary() which creates a memory usage summary
10905 file with extension .mem. Reports of overlaping stack and small stack
10906 size. If the space for the stack is less than 16 bytes aslink trows a
10909 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10910 the 8051. Option 'y' for memory summary output file.
10912 Changes to sdcc (All the changes are marked with 'JCF'):
10914 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10916 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10917 overlaying area for it (uses RegBankUsed[4]).
10919 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10920 bank zero as used by default. By default aslink locates the stack
10921 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10922 the creation of the .mem file. Delegates the allocation of data area
10923 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10924 the begining of the stack area to aslink.
10926 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10927 glue() in SDCCglue.c creates an area for it.
10929 2002-09-03 Borut Razem <borut.razem AT siol.net>
10930 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10931 sdcc/src/pic/glue.c:
10932 introduced atexit() handler for teporay files removal in case of
10933 errors, assertions, ...
10935 2002-08-29 Borut Razem <borut.razem AT siol.net>
10936 * sdcc/support/cpp2/auto-host_vc_in.h:
10937 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10938 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10939 Maybe there is a similar problem with BORLANDC? It should be checked!
10941 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10942 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10943 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10944 was not executed, and the compiler (cl) launched a warning:
10945 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10947 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10948 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10950 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10951 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10953 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10954 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10955 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10956 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10957 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10958 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10959 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10960 - added Release configuration in VS projects
10961 - review of compiler an linker options
10962 - VC .exe files are generated in bin_vc directory, not to interfere
10963 with binaries generated from other projects (cygwin, mingw, bcc ...)
10965 * sdcc/src/yacc.dsp: added
10967 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10968 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10969 and insert the version number definitions from .version
10971 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10973 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10974 added - genarate auto-host.h using auto-host_vc_in.h as template
10977 removed from CVS, generated automatically
10979 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10980 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10982 2002-08-11 Borut Razem <borut.razem AT siol.net>
10983 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10985 2002-08-10 Borut Razem <borut.razem AT siol.net>
10986 * src/SDCCmain.c (main):
10987 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10988 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10989 The consequence was that some temporary files were not removed.
10992 unification of code in functions tempfilename() and tempfile():
10993 function tempnam() is defined in Visual Studio 6.0 and .NET
10995 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10997 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10998 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10999 - removed compiler command line option /WX: Treats all warnings as errors
11000 - update a list of source files, included into the project
11002 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11003 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11004 changed project type to Generic Project so that can be correcly converted to VS.NET project
11006 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11008 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11010 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11012 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11013 added return 0 statements after assert() to make compiler happy
11015 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11016 added newline in the def file to keep MSC compiler satisfied
11018 * sdcc/src/z80/gen.c:
11019 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11020 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11021 - solved MSC error in function aopDump()
11023 * sdcc_vc.h: define PREFIX as "\\sdcc"
11025 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11026 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11029 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11030 - Rewrote the register banking algorithm.
11031 - Added pCode live-range analysis to registers (for now, only non-used and
11032 singly-used registers optimized away)
11034 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11036 * 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.

11059 * src/z80/main.c: Added force callee saves for jaune.
11061 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11063 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11065 2002-03-28 Johan Knol <johan AT balder>
11067 * src/SDCCval.c: fixed bug #532436
11069 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11071 Added "char *Processor" field to the port structure.
11074 Added -p option. Allows port dependent processor to be specified.
11077 Initialized the new field char *Processor field to NULL in all ports
11080 Compiler generated registers for interrupt context saving
11081 were not getting allocated.
11083 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11086 Fixed left shift. Will promote the left side of a left shift
11087 if a) left shifting more than size of operand or b) when assigned
11088 to something size > size of left side
11090 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11092 tons of changes. Register allocation has been
11093 rewritten. Added customization for the various PICs. Flow
11094 analysis is restructured. ...
11096 * src/pic/device.h:
11099 * src/pic/device.c:
11100 Added. device.c is a PIC port hack to accomodate variations
11103 2002-03-13 Michael Hope <michaelh AT vroom>
11105 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11107 2002-03-04 johanknol <johanknol AT manik>
11109 * /src/SDCCval.c: fixed
11111 const unsigned char arr[][2] = { { 0, 1 } };

11198 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11200 * sdcc/src/SDCCloop.c:
11201 Previous fix was not good. basic blocks that have "break" or "return" are
11202 not really partof a loop , but live ranges used in these blocks should
11203 be live thru the entire loop, so set partOfLoop but don't add them to
11206 2002-02-21 <johan AT FRIJA>
11208 * src/SDCCcse.c: fixed bug #514308
11210 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11213 Fixed BUG #519583. If a conditional block ended in a return/break
11214 statement inside a loop, it was not being considered part of the loop.
11216 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11218 2002-02-10 Karl Bongers <karl AT turbobit.com>

11224 * device/examples/test2.c:
11225 Fix bug, "red" variable not being initialized(compiler complained).
11227 * device/examples/Makefile, examples/test3.c:
11228 Add Makefile in device/examples folder, compiles test3.c
11229 for use as a multiple module SDCDB test case.
11231 * sim/ucsim/cmd.src/cmdset.cc:
11232 Took out debug printfs in ucsim "next" command.
11234 * sim/ucsim/xa.src:
11235 Karl and Johan start ucsim XA support. Most dissassembly working,
11236 about 75% emulation done(plenty of work remaining).
11238 * sim/ucsim/z80.src:
11239 Add Z80 support to ucsim, add test-ucz80 regression test,
11240 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11241 Notice z80 compiler fails on examples/test3.c/crc code.
11243 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11245 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

11253 from a memory mapped port
11254 2) added __builtin_memcmp
11255 3) added __builtin_swapw swap bytes of a short
11257 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11258 1) handle multiple send & receives from register bank1
11259 2) ralloc can now allocate DPTR1 to some liveRanges
