978 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
980 Enabled VPATH feature: changed nearly all Makefiles (149 files).
981 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
983 One basic decision: e.g. src/clean.mk includes further files. In order
984 to make this work there are two solutions:
985 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
986 run configure on them. This way they can use
987 'include $(srcdir)/port-clean.mk'
988 - always include clean.mk by the Makefile at the same level. To avoid
989 that `make clean` tries to include and build Makefile.dep the
990 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
991 implemented, because now even `make uninstall` doesn't create
992 Makefile.in. clean.mk could be eliminated by pasting it in
995 * debugger/mcs51/Makefile.in: build own objects from library sources
996 (SLIB, SDCC) in current directory
998 * configure, configure.in: renamed --disable-device-lib-build in
999 --disable-device-lib; added --enable-doc, the required tools are
1000 searched by configure; added result message; the toolchain for the
1001 belonging ports are now only built, if the port is enabled.
1003 * support/regression/*: all output is written in directory gen, because
1004 the fwk and ports directories don't livet in the build tree using vpath
1006 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1007 --disable-device-lib, added --enable-doc, added section VPATH
1009 * sim/ucsim/configure.in,
1010 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1011 z80 are enabled by default
1013 2006-04-24 Raphael Neider <rneider AT web.de>
1015 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1016 to config word, "pic14_"-prefixed some extern functions
1017 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1018 config word has been found
1019 * src/pic/device.h: added prototypes
1020 * src/pic/pcode.c: added "pic14_"-prefix where needed
1021 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic

1037 fixes #1469504 and #1474602,
1038 (pCodeRegOptimizeRegUsage): fixed typo in comment

1311 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1312 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1328 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1329 call to allocReg, not by manually allocating a new one,
1330 (pic16_assignRegisters): now before going through the register
1331 allocating functions mark all registers as free. This eliminates some
1332 side effects resulting from peephole parser done earlier in the backbone
1334 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1382 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1384 2006-03-06 Borut Razem <borut.razem AT siol.net>
1386 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1387 made the linker quiet
1389 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1391 * src/pic16/gen.c (genPcall): fixed bug #1443644
1392 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1393 which dumps before the function entry point a data byte which represents
1394 the number of the local variables used by the specified function, added
1395 'xinst' for initial support for Extended Instruction Support,
1396 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1397 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1398 port->fun_prefix anymore (may change later),

1411 --extended or -y for Extended Instruction Support,
1412 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1413 (deassignLRs): *** perhaps the most important change, old 'for' code
1414 (commented out for reference), didn't account for some registers which
1415 were left marked 'not free' after a pointer operation. The change
1416 reduces register usage a lot in some cases

3691 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3692 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3693 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3694 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3695 always available in leading double underscore form. The C99 support is
3696 mostly missing, but it's a start.
3697 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3698 reserved identifier "__data".
3700 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3774 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3776 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3778 * device/lib/printf_large.c: removed inline assembly for portability and
3779 readability. Use printf_fast if speed or size are more important.
3780 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3781 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3783 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3785 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3786 prevent compiler warning
3788 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3790 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3791 moved to level 0 and declared as static. Also they are explicit
3792 placed in access bank. This was necessery because some times they
3793 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3794 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3795 optimizations. Currently only compare to unsigned char is implemented,
3796 * src/pic16/gen.c: added fReturnIdx array,
3797 * (struct resolvedIfx) is moved to gen.h and made public,
3798 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3799 * (aopForSym): added an optimization to directly store in stack of
3800 the operand of a SEND iCode,
3801 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3802 but as registers instead (AOP_REG) using the fReturnIdx array,
3803 * (pic16_freeAsmop): remove the freed register from the
3804 _G.sregsAlloc field,
3805 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3806 a compare of 'WREG',
3807 * (pic16_popGetTempRegCond): changed function prototype, now
3808 function takes also a bitVector argument v which holds the current
3809 set of registers that are allocated for stack access by aopForSym,
3810 registers allocated in aopForSym for accessing stack symbols are not
3811 any more part of the functions usedRegs field,
3812 * (genCall): some times aopOp is called for a stack variable to be
3813 send, aopForSym might perform the push, if this is true make sure
3814 that genCall doesn't push the variable twice by testing _G.resDirect,
3815 * (genFunction): changed testing for unspecified interrupt number
3816 from 256 to INTNO_UNSPEC,
3817 * modified selection scheme of frame pointer generation. Previously
3818 if function did use local registers a frame pointer was generated,
3819 now a frame pointer is generated only if function has arguments
3820 (that need PLUSW2 register access), or has stack arguments, or the
3821 compiler is not instructed to omit the frame pointer,
3822 * (genEndFunction): before restoring local registers that were saved
3823 in the function preamble, also restore the registers that *might*
3824 have been allocated for stack access,
3825 * (genRet): removed some old comments,
3826 * (genCmp, the active (RN's) version): added a call to the
3827 pic16_genCmp_special function to perform the compare with a more
3828 robust and optimized way,
3829 * (genInline): a feature has been added in inline code generation,
3830 which allows a wildcard variable substitution when writing inline
3831 assembly. Code is incomplete and experimental therefore undocumented,
3832 * (genCast): changed order of aopOp for result and right to allow
3833 aopForSym to directly load the result if possible,
3834 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3835 perform an optimized compare on some selected special occasions,
3836 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3837 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3838 generate an IVT any more,
3839 * src/pic16/main.c (pic16_optionsTable): added command line option
3841 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3842 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3844 * src/pic16/NOTES: Raphael Neider added in list of active developers
3845 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3846 jumptable_end to prevent bug #,
3847 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3848 inCond and outCond fields,
3849 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3850 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3851 turn off register spilling,
3852 * (packRegsForOneUse): synced with other ports' versions although it
3853 is not used currently,
3854 * (pic16_packRegisters): added an optimization while reading
3855 structure bitfields, some registers may be saved (malloc code is
3856 decreased by 80 bytes)
3858 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3860 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3861 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3862 this can be optimized more?
3864 2005-03-10 Raphael Neider <rneider AT web.de>
3866 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3867 genNearPointerGet): (hopefully) fixed access to bitfields via
3868 pointers (p->bitN = x; and x = p->bitN; failed)
3870 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3872 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3874 2005-03-09 Raphael Neider <rneider AT web.de>

3878 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3880 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
3881 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
3882 (regTypeNum): set REG_BIT type if necessary
3883 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

4500 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4502 Adding support for replacing ljmps with sjmps in jumptables
4503 generated for switch statements. For now you need to set the
4504 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4505 Now 4 algorithms for mcs51 jumptable generation are used:
4506 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4507 addresses loaded pc-relative for up to 112 cases and stack-pushing
4508 target addresses loaded with offset from dptr for up to 256 cases.

4538 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4540 * added libc directory. The current version of LibC contains string
4541 functions, ctype functions and macros and some functions of the
4542 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4543 be extensively tested in the future. Standard disclaimer here.
4544 Library is not automatically build yet. But one can build it by
4545 invoking 'make' inside the libc directory.

4552 temporary registers, its a buggy feature and will be removed,
4553 * (pic16_popGet): set register instance field in AOP_CRY,
4554 * (pic16_outBitC): fixed for results in size greater than 1,
4555 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4556 * (pic16_storeForReturn): optimized return of 0,
4557 * (genCmp): experimental code for new genCmp which uses PIC18's
4558 special compare&skip instructions. Initial tests fail some times
4559 with variables grater than 1 byte in size, so new code is disabled,
4560 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4562 * (genCast): began a fix to optimize the casting of a bit to another
4563 bit, now assigning a bitfield to another bitfield will fail, sorry,
4564 * src/pic16/main.c: disabled the use of lr-support feature,
4565 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4571 * (isBankInstruction): modified to return 0 for no banking instruction,
4572 and 1 for banking instruction,
4573 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4574 caused stop processing pCodes after a inline assembly block,
4575 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4576 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4577 registers when it shouldn't,
4578 * src/pic16/ralloc.c (allocReg): add preliminary support for
4579 supporting a limited set of temporary registers,
4581 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4583 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4584 genDataPointerSet): ensure assignments always copy in MSB to LSB
4586 (loadRegFromAop): recognize CLRH optimization,
4587 (genFunction): optimize RECEIVE iCodes in reentrant functions
4589 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4591 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7589 loaded with the linker search paths (-L arguments) and the libraries
7590 to be linked with the current source (-l arguments). Changes
7591 currently will affect only the pic16 port.
7592 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7593 include path the port specific paths and port specific libraries,
7594 * gplink command now contains the $3 argument,
7595 * src/pic16/device.h,

7612 Documenting changes from previous commits.
7613 * configure.in (version 1.56),
7614 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7615 when generating output files to configure the pic16 library,
7616 but now I've commented it out, since gputils aren't installed in the
7617 SF compile farm, so library won't compile
7619 * device/lib/Makefile.in (version 1.56): initially I've added in
7620 target 'all' the prerequestive 'model-pic16' so it compiled the
7621 pic16 library, but now I've commented it out for the same reasons
7623 * added targets 'model-pic16' and 'objects-pic16' to compile the
7625 * added target 'port-specific-objects-pic16' to handle the
7626 generated libraries and copy them into the build/ directory
7627 * added target 'clean-intermediate-pic16' to clean intermediate
7628 files into pic16 directory
7629 * in target 'installdirs' added line to create directory pic16 in

7895 * src/SDCCsymt.c (newEnumType),
7897 * support/Util/SDCCerr.c,
7898 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7900 * support/regression/tests/enum.c: added test for enum values that
7901 require at least 2 bytes of storage.
7903 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7905 * src/common.h: added ifndef/define/endif macros
7906 around the header file.
7907 Bug reported from Jesus Calvino-Fraga
7909 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7911 * sdcc.spec: updated
7912 * device/include/Makefile.in: don't install CVS directories
7913 * device/lib/Makefile.in: added removal of CVS directories after install
7914 * doc/Makefile: fixed install, added local_icons
7915 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7916 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7917 * src/ds390/gen.c (genRightShift): fixed bug #870788
7918 * src/SDCCast.c (decorateType): fixed bug #870781
7920 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7922 PIC16 port related changes:
7923 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7924 added variable stackPos,
7926 * gen.c: genCall, assignResultValue: added support for
7927 pushing/retrieving function parameters to/from stack,
7928 genFunction,genEndFunction: setup stack frame for the
7930 genAddrOf: will be changed according to bug 863624
7932 * added files genutils.c and genutils.h which contain gen*
7933 debugged and optimised functions extracted from gen.c
7935 * glue.c: added variable 'externs' which holds extern symbols,
7936 pic16emitRegularMap: is modified to properly handle relocatable
7937 symbols under the new scheme,
7938 pic16createInterruptVect: is modified
7939 pic16printPublics: is modified to emit 'global' assembler directives,
7940 added pic16_printExterns to print extern symbols,
7941 pic16glue: initializes stack/frame pointer in the beginning of
7942 the assembly output. Temporary hack, will be corrected later,
7943 because gplink yet does not support stack and SDCC does not
7944 yet support a type of crt0.o object to create the final binary.
7946 * Removed many lines that contain 8051 legacy code.
7947 * The code is finally placed under a 'code' directive.
7948 * Added port specific options.
7950 * _process_pragma: simplified since now we do not need *special*
7951 include file to define SFR registers. But a separate header
7952 will be needed. This will be developed later.
7953 * _pic16_parseOptions: added, parses port specific options:
7954 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7955 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7956 --preplace-udata-with=
7958 * _pic16_setDefaultOptions: modified to initialize section names,
7959 but hack is temporarly out of order since it needs improvement.
7960 * _pic16_genAssemblerPreamble: configuration words are emitted by
7961 their address instead of their name. This part is incomplete and
7962 supports only the 18Fxx2 devices. Other devices will emit an error
7963 during assembly since they do not contain the same set of config
7965 * _pic16_genIVT: is modified,
7967 * pcode.c: added definitions for some hardware registers that are needed
7969 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7970 All PCI entries are updated. Now LFSR is supported.
7971 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7972 * added pic16_newpCodeOpLit2 to support instructions with
7973 two literal arguments
7974 * pic16_pCode2str: corrected code that emits assembler instructions
7975 with two literal operands and those that have an access bit modifier
7976 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7977 this fixes a bug which caused some labels to be lost, when an
7978 assembler directive was added, i.e. banksel,
7979 * pic16_FixRegisterBanking: improved logic that causes the insertion
7981 * InlineFunction: functions that are called once, are not any more
7982 inlined. This can be a port option in the future,
7984 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7986 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7987 hold the corresponding uninitialized symbols,
7988 * pic16_allocProcessorRegister: registers have explicit marked the
7990 * pic16_allocInternalRegister: registers are explicit marked as
7992 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7993 processing list, so bit registers were lost,
7996 * ralloc.h: added field 'accessBank' and original symbol operand
7997 in register definition,
7998 * removed the field isMapped from register definition,
8000 ** Several functions have been removed from various sources:
8001 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8002 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8003 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8004 pic16_assignRelocatableRegisters
8006 ** others have been introduced:
8007 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8008 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8010 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8012 * support/scripts/inc2h.pl: changed definition of BIT_AT
8013 to emit 'sbit at' instead of 'bit at'. This was a request.
8015 PIC16 port related preliminary changes:
8016 * gen.c: prefixed function popRegFromString with
8017 pic16_ and all references to it corrected
8018 * pcode.c: all pic16_pc_* hardware registers prefixed
8019 with underscore (_),
8020 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8021 * ralloc.c: newReg(): when register is REG_SFR then
8022 set address to rIdx,
8023 pic16_allocProcessorRegister(): marks register wasUsed=0
8024 pic16_writeUsedRegs(): added a call to assign processor
8025 registers via pic16_assignFixedRegisters
8027 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8029 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8030 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8031 variables in unused register banks. Also the SSEG is placed
8032 wherever there is enough space for it, and IDATA can be anywhere
8033 in internal RAM. For now compile using -Wl-Y[stack_size].
8034 The mem file is different for this option as well, since it
8035 makes no sense of talking about DSEG lenght.
8037 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8039 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8040 in certain cases, e.g. when ROM assignment, patch provided
8041 from Albert den Haan.

8282 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8284 * src/SDCCast.c (decorateType): disabled a transformation I added in
8285 revision 1.188 (access to fields of a structure at an absolute address);
8286 it breaks with bitfields, extern declarations, and gcse analysis.
8287 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8288 could be assigned through a pointer, so don't complain.
8289 * src/SDCCast.c (astErrors),
8291 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8929 support for standard C idiom of memory mapped variables; for
8930 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8931 to xdata int at 0x1234 tempvar = 1.
8932 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8933 provided by Akiya ISHIDA

8949 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8951 Fixed bug #621531 (const & volatile confusion in the type chain).
8952 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9044 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9045 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9046 fetching of the pointer
9047 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9048 copied from genNearPointerSet()
9049 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9050 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9064 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9066 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9067 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9068 type for bits was changed. It resulted in bit variables becoming
9069 global, which is not permitted in PIC 14 assembly output.
9071 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9073 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9086 A few small changes that speed up the peephole optimizer.
9090 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9092 Try to make the peephole optimizer smarter by maintaining
9093 an association between the assembly source code and the
9094 iCodes that originated them. Put this information to use
9095 with a new peephole rule condition "notVolatile" so that
9096 the rules can be aggressive yet still safe.
9101 * src/mcs51/peeph.def
9103 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9107 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9108 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9109 if the left or right operand symbols have the accuse flag set.
9111 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9113 Changed the type of the result of the ! (NOT) operator to char;
9114 previously it returned the same type as the source. This allows
9115 us to eliminate all the genFloatNot functions (all of its target
9116 implementations were very buggy) since !float can use the same
9119 * src/SDCCicode.c (ast2iCode): ! returns char

9128 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9129 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9130 during interrupts. Ensure WSAVE is located at a shared bank address.
9131 2. Fixed page selection in some places
9132 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9133 the registers name strings.
9134 4. Fixed "signed / unsigned compare" compiler warnings.
9135 5. The PIC port manages its own allocation of the general purpose
9136 registers, but makes no attempt to reuse them. As a result when
9137 compiling it soon runs out of general purpose registers. Some
9138 additional code was added to the files pcode.c and device.c to walk
9139 through the function call tree and rename the registers so that they
9149 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9150 genPlus() & genMinus() when the result is the same as left or right

9156 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9158 Made bitfield a distinct type from bit so that bitfields
9159 convert as per ANSI C and bits retain their traditional
9160 boolean style behaviour. Implemented bitfield support in
9168 * src/ds390/gen.c: bit v bitfield split
9169 * src/z80/gen.c: New support for bitfields
9170 * support/regression/tests/bitfields.c: reenabled z80,
9173 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9175 Rules 246.x, 247.x relate to bitfields, the others speed up
9176 access to xdata mapped I/O devices.
9178 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9180 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9182 Cleaned up genPackBits and genUnpackBits and added two helper
9183 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9184 for literal assignments in genPackBits (thanks to Frieder for
9190 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9192 Fixed bug #748310 (pointer to function type mishandled when the
9193 function name is omitted). Also fixed a SIGSEGV when a function
9194 attribute (reentrant, etc) is used on a non-function or on a
9195 function but misplaced before the parameter list.
9197 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9199 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9200 * support/Util/SDCCerr.h,
9201 * support/Util/SDCCerr.c: Added func attr misuse error msg

9222 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9224 Made the constant following the "interrupt" keyword optional. If
9225 omitted, the function will not automatically be given an entry
9226 in the interrupt vector table (similar to #pragma NOIV, but
9227 less syntacticly kludgy). The interrupt number is also now
9228 range checked. Also fixed a bug in the high order bit example

9242 * src/SDCCicode.c (operandOperation): rewritten some ops
9243 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9244 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9246 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9247 be re-activated by defining REDUCE_LITERALS)
9248 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9249 unsigned, but are signed by default
9250 * src/SDCCval.c (constVal): rearranged
9251 * src/SDCCval.c (valMod): preliminary fix
9252 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9758 added if/endif conditional macros to remove options help
9759 messages from optionsTable when a port is not configured, added
9760 support for the PIc16 port in the ports table, when executing
9761 the compiler with no port specified on command line, a default
9762 port is selected with the new macro DEFAULT_PORT which is
9763 defined in port.h, in setDefaultOptions() linkOptions is removed
9764 from initialization assignment, since now it is a set,
9765 parseCmdLine uses setParseWithComma for linkOptions, in
9766 linkEdit() linkOptions are accessed with new function indexSet()
9767 which returns the i'th item of a set variable. See SDCCset.c, in
9768 linkEdit() when calling buildCmdLine(), added linkOptions as
9769 last argument. Now users can pass arguments to gplink via the
9770 -Wl option, main() uses pic16glue() to glue up pic16 programs

9784 gpasm complaining and test the linkage with gplink, _linkCmd and
9785 _asmCmd changed to be more gplink and gpasm friendly
9786 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9787 produced an error when parsed, peep rule 12 is added to utilize
9788 movff, but it is commented out since the pCode does not support
9789 yet a command with 2 address arguments
9791 2003-05-18 <johan AT balder>
9793 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9820 2003-05-11 Borut Razem <borut.razem AT siol.net>
9822 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10813 * src/SDCCast.c (decorateType): fixed bug #600035
10815 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10816 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10817 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10818 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

10826 2003-01-06 <johan AT balder>
10828 * src/SDCCicode.c: fixed array add
10830 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10831 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10832 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10834 2003-01-04 <johan AT balder>
10836 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10838 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10839 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10841 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10842 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10843 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10845 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10846 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10848 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10849 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10851 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10852 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10854 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10856 * in /sdcc/as/mcs51/ changed these files in order to create an
10857 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10858 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10859 following files to include the previous two files: aslink.dsp,
10860 Makefile.aslink, Makefile.bcc, and Makefile.in.
10862 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10863 .adb instead of .cdb
10865 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10867 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10868 value from option --iram-size.
10870 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10872 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10875 2002-09-18 <wiml AT hhhh.org>
10877 * SDCClrange.h: exposed setFromRange() and setToRange()
10878 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10879 packRegsForAccUse() (bug 542397)
10880 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10881 multiple times and emitting the fetch operations more than once
10882 added aopGetUsesAcc() function to allow binary operators to
10883 fetch their operands in the correct order; made genMinus() emit
10884 compact code for X = LITERAL - Y
10886 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10887 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10888 sprintf() in line 1267.
10890 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10891 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10894 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10895 Changes to aslink (All the changes are marked with 'JCF'):
10897 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10900 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10901 area BSEG. Also moves, if possible, the DATA area down into the internal
10902 ram so more space is available.
10904 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10907 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10908 not bytes. Function summary() which creates a memory usage summary
10909 file with extension .mem. Reports of overlaping stack and small stack
10910 size. If the space for the stack is less than 16 bytes aslink trows a
10913 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10914 the 8051. Option 'y' for memory summary output file.
10916 Changes to sdcc (All the changes are marked with 'JCF'):
10918 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10920 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10921 overlaying area for it (uses RegBankUsed[4]).
10923 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10924 bank zero as used by default. By default aslink locates the stack
10925 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10926 the creation of the .mem file. Delegates the allocation of data area
10927 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10928 the begining of the stack area to aslink.
10930 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10931 glue() in SDCCglue.c creates an area for it.
10933 2002-09-03 Borut Razem <borut.razem AT siol.net>
10934 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10935 sdcc/src/pic/glue.c:
10936 introduced atexit() handler for teporay files removal in case of
10937 errors, assertions, ...
10939 2002-08-29 Borut Razem <borut.razem AT siol.net>
10940 * sdcc/support/cpp2/auto-host_vc_in.h:
10941 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10942 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10943 Maybe there is a similar problem with BORLANDC? It should be checked!
10945 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10946 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10947 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10948 was not executed, and the compiler (cl) launched a warning:
10949 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10951 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10952 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10954 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10955 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10957 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10958 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10959 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10960 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10961 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10962 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10963 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10964 - added Release configuration in VS projects
10965 - review of compiler an linker options
10966 - VC .exe files are generated in bin_vc directory, not to interfere
10967 with binaries generated from other projects (cygwin, mingw, bcc ...)
10969 * sdcc/src/yacc.dsp: added
10971 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10972 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10973 and insert the version number definitions from .version
10975 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10977 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10978 added - genarate auto-host.h using auto-host_vc_in.h as template
10981 removed from CVS, generated automatically
10983 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10984 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10986 2002-08-11 Borut Razem <borut.razem AT siol.net>
10987 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10989 2002-08-10 Borut Razem <borut.razem AT siol.net>
10990 * src/SDCCmain.c (main):
10991 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10992 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10993 The consequence was that some temporary files were not removed.
10996 unification of code in functions tempfilename() and tempfile():
10997 function tempnam() is defined in Visual Studio 6.0 and .NET
10999 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11001 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11002 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11003 - removed compiler command line option /WX: Treats all warnings as errors
11004 - update a list of source files, included into the project
11006 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11007 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11008 changed project type to Generic Project so that can be correcly converted to VS.NET project
11010 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11012 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11014 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11016 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11017 added return 0 statements after assert() to make compiler happy
11019 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11020 added newline in the def file to keep MSC compiler satisfied
11022 * sdcc/src/z80/gen.c:
11023 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11024 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11025 - solved MSC error in function aopDump()
11027 * sdcc_vc.h: define PREFIX as "\\sdcc"
11029 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11030 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11033 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11034 - Rewrote the register banking algorithm.
11035 - Added pCode live-range analysis to registers (for now, only non-used and
11036 singly-used registers optimized away)
11038 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11040 * 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.

11057 * device/lib/z80/printf.c (sprintf): Added.
11059 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11061 * src/z80/peeph.def: Added transpose redundent load rule.
11063 * src/z80/main.c: Added force callee saves for jaune.
11065 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11067 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11069 2002-03-28 Johan Knol <johan AT balder>
11071 * src/SDCCval.c: fixed bug #532436
11073 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11075 Added "char *Processor" field to the port structure.
11078 Added -p option. Allows port dependent processor to be specified.
11081 Initialized the new field char *Processor field to NULL in all ports
11084 Compiler generated registers for interrupt context saving
11085 were not getting allocated.
11087 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11090 Fixed left shift. Will promote the left side of a left shift
11091 if a) left shifting more than size of operand or b) when assigned
11092 to something size > size of left side
11094 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11096 tons of changes. Register allocation has been
11097 rewritten. Added customization for the various PICs. Flow
11098 analysis is restructured. ...
11100 * src/pic/device.h:
11103 * src/pic/device.c:
11104 Added. device.c is a PIC port hack to accomodate variations
11107 2002-03-13 Michael Hope <michaelh AT vroom>
11109 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11111 2002-03-04 johanknol <johanknol AT manik>
11113 * /src/SDCCval.c: fixed
11115 const unsigned char arr[][2] = { { 0, 1 } };

11202 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11204 * sdcc/src/SDCCloop.c:
11205 Previous fix was not good. basic blocks that have "break" or "return" are
11206 not really partof a loop , but live ranges used in these blocks should
11207 be live thru the entire loop, so set partOfLoop but don't add them to
11210 2002-02-21 <johan AT FRIJA>
11212 * src/SDCCcse.c: fixed bug #514308
11214 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11217 Fixed BUG #519583. If a conditional block ended in a return/break
11218 statement inside a loop, it was not being considered part of the loop.
11220 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11222 2002-02-10 Karl Bongers <karl AT turbobit.com>

11228 * device/examples/test2.c:
11229 Fix bug, "red" variable not being initialized(compiler complained).
11231 * device/examples/Makefile, examples/test3.c:
11232 Add Makefile in device/examples folder, compiles test3.c
11233 for use as a multiple module SDCDB test case.
11235 * sim/ucsim/cmd.src/cmdset.cc:
11236 Took out debug printfs in ucsim "next" command.
11238 * sim/ucsim/xa.src:
11239 Karl and Johan start ucsim XA support. Most dissassembly working,
11240 about 75% emulation done(plenty of work remaining).
11242 * sim/ucsim/z80.src:
11243 Add Z80 support to ucsim, add test-ucz80 regression test,
11244 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11245 Notice z80 compiler fails on examples/test3.c/crc code.
11247 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11249 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
11250 Added support for --parms-in-bank1
11252 * src/ds390/peeph.def:
11253 added a few more peephole optimzations
