649 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
651 Enabled VPATH feature: changed nearly all Makefiles (149 files).
652 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
654 One basic decision: e.g. src/clean.mk includes further files. In order
655 to make this work there are two solutions:
656 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
657 run configure on them. This way they can use
658 'include $(srcdir)/port-clean.mk'
659 - always include clean.mk by the Makefile at the same level. To avoid
660 that `make clean` tries to include and build Makefile.dep the
661 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
662 implemented, because now even `make uninstall` doesn't create
663 Makefile.in. clean.mk could be eliminated by pasting it in
666 * debugger/mcs51/Makefile.in: build own objects from library sources
667 (SLIB, SDCC) in current directory
669 * configure, configure.in: renamed --disable-device-lib-build in
670 --disable-device-lib; added --enable-doc, the required tools are
671 searched by configure; added result message; the toolchain for the
672 belonging ports are now only built, if the port is enabled.
674 * support/regression/*: all output is written in directory gen, because
675 the fwk and ports directories don't livet in the build tree using vpath
677 * doc/sdccman.lyx: renamed --disable-device-lib-build to
678 --disable-device-lib, added --enable-doc, added section VPATH
680 * sim/ucsim/configure.in,
681 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
682 z80 are enabled by default
684 2006-04-24 Raphael Neider <rneider AT web.de>
686 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
687 to config word, "pic14_"-prefixed some extern functions
688 (pic14_emitConfigWord): emit __config directive(s) if assignment to
689 config word has been found
690 * src/pic/device.h: added prototypes
691 * src/pic/pcode.c: added "pic14_"-prefix where needed
692 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
694 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

952 2006-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
954 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
955 implemented patch 1120823 Thanks to Willy De la Court (normal
956 interrupts need an interrupt number now if they are made critical),
957 and enabled nesting of critical functions though not for gbz80
958 (genCritical, genEndCritical): added functions
959 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
960 * src/z80/mappings.i: added "ei" to all mappings
962 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
964 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
965 submitted by the Debian SDCC maintainer Aurelien Jarno:
966 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
967 archive with gcc 4.1 on mips and wrote the patch"
969 2006-03-16 Raphael Neider <rneider AT web.de>
971 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
972 the left operand is shorter than the result (c* = lit-c* + int),
974 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
977 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
979 * src/.version: increased version number to 2.5.5
980 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
981 linking is done manually in pic16 port's _linkEdit,
982 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
983 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
984 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
985 allocate asmop as AOP_ACC,
986 (aopForRemat): added parameter 'bool result' in function declaration,
987 (pic16_aopGet): return AOP_ACC when accessing WREG,
988 (pic16_popGetTempReg): minor modification,
989 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
990 'pic16_allocWithIdx',
991 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
992 calling function in absolute addresses,
993 (genAssign): take into account AOP_ACC asmop,
994 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
995 * src/pic16/pcoderegs.c: some debug functions and lines added,
996 * src/pic16/ralloc.c (decodeRegType): added but commented out,
997 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
999 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1000 call to allocReg, not by manually allocating a new one,
1001 (pic16_assignRegisters): now before going through the register
1002 allocating functions mark all registers as free. This eliminates some
1003 side effects resulting from peephole parser done earlier in the backbone
1005 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1007 * src/SDCCicode.c (geniCodeLogic),

1026 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1027 (aopForSym, aopOp): increment asmop.allocated if reused,
1028 (freeAsmop): decrement asmop.allocated and check for zero instead of
1030 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1031 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1058 made the linker quiet
1060 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1062 * src/pic16/gen.c (genPcall): fixed bug #1443644
1063 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1064 which dumps before the function entry point a data byte which represents
1065 the number of the local variables used by the specified function, added
1066 'xinst' for initial support for Extended Instruction Support,
1067 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1068 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1069 port->fun_prefix anymore (may change later),
1070 (genFunction, genEndFunction): do not store/restore local registers for
1071 _main (this should take care the --main-return command line option in
1073 (genOr): removed some legacy pic-port instructions,
1074 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1075 performing operations with SFR's causes data to be written more than
1076 once to each SFR. Perhaps SFRs should be handled in special cases...
1077 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1079 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1080 into account for stack starting position,
1081 (struct OPTIONS pic16_optionsTable): added command line argument
1082 --extended or -y for Extended Instruction Support,
1083 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1084 (deassignLRs): *** perhaps the most important change, old 'for' code
1085 (commented out for reference), didn't account for some registers which
1086 were left marked 'not free' after a pointer operation. The change
1087 reduces register usage a lot in some cases

3457 prevent compiler warning
3459 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3461 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3462 moved to level 0 and declared as static. Also they are explicit
3463 placed in access bank. This was necessery because some times they
3464 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3465 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3466 optimizations. Currently only compare to unsigned char is implemented,
3467 * src/pic16/gen.c: added fReturnIdx array,
3468 * (struct resolvedIfx) is moved to gen.h and made public,
3469 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3470 * (aopForSym): added an optimization to directly store in stack of
3471 the operand of a SEND iCode,
3472 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3473 but as registers instead (AOP_REG) using the fReturnIdx array,
3474 * (pic16_freeAsmop): remove the freed register from the
3475 _G.sregsAlloc field,
3476 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3477 a compare of 'WREG',
3478 * (pic16_popGetTempRegCond): changed function prototype, now
3479 function takes also a bitVector argument v which holds the current
3480 set of registers that are allocated for stack access by aopForSym,
3481 registers allocated in aopForSym for accessing stack symbols are not
3482 any more part of the functions usedRegs field,
3483 * (genCall): some times aopOp is called for a stack variable to be
3484 send, aopForSym might perform the push, if this is true make sure
3485 that genCall doesn't push the variable twice by testing _G.resDirect,
3486 * (genFunction): changed testing for unspecified interrupt number
3487 from 256 to INTNO_UNSPEC,
3488 * modified selection scheme of frame pointer generation. Previously
3489 if function did use local registers a frame pointer was generated,
3490 now a frame pointer is generated only if function has arguments
3491 (that need PLUSW2 register access), or has stack arguments, or the
3492 compiler is not instructed to omit the frame pointer,
3493 * (genEndFunction): before restoring local registers that were saved
3494 in the function preamble, also restore the registers that *might*
3495 have been allocated for stack access,
3496 * (genRet): removed some old comments,
3497 * (genCmp, the active (RN's) version): added a call to the
3498 pic16_genCmp_special function to perform the compare with a more
3499 robust and optimized way,
3500 * (genInline): a feature has been added in inline code generation,
3501 which allows a wildcard variable substitution when writing inline
3502 assembly. Code is incomplete and experimental therefore undocumented,
3503 * (genCast): changed order of aopOp for result and right to allow
3504 aopForSym to directly load the result if possible,
3505 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3506 perform an optimized compare on some selected special occasions,
3507 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3508 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3509 generate an IVT any more,
3510 * src/pic16/main.c (pic16_optionsTable): added command line option
3512 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3513 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3515 * src/pic16/NOTES: Raphael Neider added in list of active developers
3516 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3517 jumptable_end to prevent bug #,
3518 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3519 inCond and outCond fields,
3520 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3521 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3522 turn off register spilling,
3523 * (packRegsForOneUse): synced with other ports' versions although it
3524 is not used currently,
3525 * (pic16_packRegisters): added an optimization while reading
3526 structure bitfields, some registers may be saved (malloc code is
3527 decreased by 80 bytes)
3529 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3531 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3532 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3533 this can be optimized more?
3535 2005-03-10 Raphael Neider <rneider AT web.de>
3537 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3538 genNearPointerGet): (hopefully) fixed access to bitfields via
3539 pointers (p->bitN = x; and x = p->bitN; failed)

3865 access stack and frame pointers. They are initially assigned to
3866 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3867 accessing SFRs. Updated all occurences of modification of stack or
3868 frame pointer in gen.c and pcode.c,
3869 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3870 assigning of a literal value to pointers,

3913 from Raphael Neider,
3914 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
3915 for 8-bit literals. This fixes some literal operands which are sign
3916 extended to 16-bits ints when instruction needs only 8-bits.

4173 Adding support for replacing ljmps with sjmps in jumptables
4174 generated for switch statements. For now you need to set the
4175 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4176 Now 4 algorithms for mcs51 jumptable generation are used:
4177 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4178 addresses loaded pc-relative for up to 112 cases and stack-pushing
4179 target addresses loaded with offset from dptr for up to 256 cases.

4211 * added libc directory. The current version of LibC contains string
4212 functions, ctype functions and macros and some functions of the
4213 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4214 be extensively tested in the future. Standard disclaimer here.

4227 * (pic16_storeForReturn): optimized return of 0,
4228 * (genCmp): experimental code for new genCmp which uses PIC18's
4229 special compare&skip instructions. Initial tests fail some times
4230 with variables grater than 1 byte in size, so new code is disabled,
4231 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4233 * (genCast): began a fix to optimize the casting of a bit to another
4234 bit, now assigning a bitfield to another bitfield will fail, sorry,

4243 and 1 for banking instruction,
4244 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4245 caused stop processing pCodes after a inline assembly block,
4246 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4248 registers when it shouldn't,
4249 * src/pic16/ralloc.c (allocReg): add preliminary support for
4250 supporting a limited set of temporary registers,
4252 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4258 (genFunction): optimize RECEIVE iCodes in reentrant functions
4260 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7260 loaded with the linker search paths (-L arguments) and the libraries
7261 to be linked with the current source (-l arguments). Changes
7262 currently will affect only the pic16 port.
7263 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7264 include path the port specific paths and port specific libraries,
7265 * gplink command now contains the $3 argument,
7266 * src/pic16/device.h,
7267 * src/pic16/device.c,: structure PIC_device is made public and
7268 renamed to PIC16_device, the same for variable Pics which is renamed

7283 Documenting changes from previous commits.
7284 * configure.in (version 1.56),
7285 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7286 when generating output files to configure the pic16 library,
7287 but now I've commented it out, since gputils aren't installed in the
7288 SF compile farm, so library won't compile
7290 * device/lib/Makefile.in (version 1.56): initially I've added in
7291 target 'all' the prerequestive 'model-pic16' so it compiled the
7292 pic16 library, but now I've commented it out for the same reasons
7294 * added targets 'model-pic16' and 'objects-pic16' to compile the
7296 * added target 'port-specific-objects-pic16' to handle the
7297 generated libraries and copy them into the build/ directory
7298 * added target 'clean-intermediate-pic16' to clean intermediate
7299 files into pic16 directory
7300 * in target 'installdirs' added line to create directory pic16 in

7322 option so that it actually works. Made it specific to the z80, since
7323 the gbz80 doesn't have these kinds of I/O ports.
7325 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7327 * device/include/z180.h,

7546 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7547 LEFT_OP (left shift)
7549 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7551 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7552 (default behaviour).
7554 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7556 A python script to validate compiler diagnostic messages. It can be
7557 used to verify that sdcc complains about bad c source code and
7558 gives a good location of the error.
7559 * support/valdiag/Makefile,
7560 * support/valdiag/valdiag.py,
7561 * support/valdiag/tests/*

7578 Bug reported from Jesus Calvino-Fraga
7580 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7582 * sdcc.spec: updated
7583 * device/include/Makefile.in: don't install CVS directories
7584 * device/lib/Makefile.in: added removal of CVS directories after install
7585 * doc/Makefile: fixed install, added local_icons
7586 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7587 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7588 * src/ds390/gen.c (genRightShift): fixed bug #870788
7589 * src/SDCCast.c (decorateType): fixed bug #870781
7591 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7593 PIC16 port related changes:
7594 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7595 added variable stackPos,
7597 * gen.c: genCall, assignResultValue: added support for
7598 pushing/retrieving function parameters to/from stack,
7599 genFunction,genEndFunction: setup stack frame for the
7601 genAddrOf: will be changed according to bug 863624
7603 * added files genutils.c and genutils.h which contain gen*
7604 debugged and optimised functions extracted from gen.c
7606 * glue.c: added variable 'externs' which holds extern symbols,
7607 pic16emitRegularMap: is modified to properly handle relocatable
7608 symbols under the new scheme,
7609 pic16createInterruptVect: is modified
7610 pic16printPublics: is modified to emit 'global' assembler directives,
7611 added pic16_printExterns to print extern symbols,
7612 pic16glue: initializes stack/frame pointer in the beginning of
7613 the assembly output. Temporary hack, will be corrected later,
7614 because gplink yet does not support stack and SDCC does not
7615 yet support a type of crt0.o object to create the final binary.
7617 * Removed many lines that contain 8051 legacy code.
7618 * The code is finally placed under a 'code' directive.
7619 * Added port specific options.
7621 * _process_pragma: simplified since now we do not need *special*
7622 include file to define SFR registers. But a separate header
7623 will be needed. This will be developed later.
7624 * _pic16_parseOptions: added, parses port specific options:
7625 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7626 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7627 --preplace-udata-with=
7629 * _pic16_setDefaultOptions: modified to initialize section names,
7630 but hack is temporarly out of order since it needs improvement.
7631 * _pic16_genAssemblerPreamble: configuration words are emitted by
7632 their address instead of their name. This part is incomplete and
7633 supports only the 18Fxx2 devices. Other devices will emit an error
7634 during assembly since they do not contain the same set of config
7636 * _pic16_genIVT: is modified,
7638 * pcode.c: added definitions for some hardware registers that are needed
7640 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7641 All PCI entries are updated. Now LFSR is supported.
7642 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7643 * added pic16_newpCodeOpLit2 to support instructions with
7644 two literal arguments
7645 * pic16_pCode2str: corrected code that emits assembler instructions
7646 with two literal operands and those that have an access bit modifier
7647 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7648 this fixes a bug which caused some labels to be lost, when an
7649 assembler directive was added, i.e. banksel,
7650 * pic16_FixRegisterBanking: improved logic that causes the insertion
7652 * InlineFunction: functions that are called once, are not any more
7653 inlined. This can be a port option in the future,
7655 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7657 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7658 hold the corresponding uninitialized symbols,
7659 * pic16_allocProcessorRegister: registers have explicit marked the
7661 * pic16_allocInternalRegister: registers are explicit marked as
7663 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7664 processing list, so bit registers were lost,
7667 * ralloc.h: added field 'accessBank' and original symbol operand
7668 in register definition,
7669 * removed the field isMapped from register definition,
7671 ** Several functions have been removed from various sources:
7672 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7673 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7674 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7675 pic16_assignRelocatableRegisters
7677 ** others have been introduced:
7678 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7679 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7681 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7683 * support/scripts/inc2h.pl: changed definition of BIT_AT
7684 to emit 'sbit at' instead of 'bit at'. This was a request.
7686 PIC16 port related preliminary changes:
7687 * gen.c: prefixed function popRegFromString with
7688 pic16_ and all references to it corrected
7689 * pcode.c: all pic16_pc_* hardware registers prefixed
7690 with underscore (_),
7691 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7692 * ralloc.c: newReg(): when register is REG_SFR then
7693 set address to rIdx,
7694 pic16_allocProcessorRegister(): marks register wasUsed=0
7695 pic16_writeUsedRegs(): added a call to assign processor
7696 registers via pic16_assignFixedRegisters
7698 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7700 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7701 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7702 variables in unused register banks. Also the SSEG is placed
7703 wherever there is enough space for it, and IDATA can be anywhere
7704 in internal RAM. For now compile using -Wl-Y[stack_size].
7705 The mem file is different for this option as well, since it
7706 makes no sense of talking about DSEG lenght.
7708 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7710 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7711 in certain cases, e.g. when ROM assignment, patch provided
7712 from Albert den Haan.
7714 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8716 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8717 fetching of the pointer
8718 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8719 copied from genNearPointerSet()
8720 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8721 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8737 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8738 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8739 type for bits was changed. It resulted in bit variables becoming
8740 global, which is not permitted in PIC 14 assembly output.

8757 A few small changes that speed up the peephole optimizer.
8761 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8763 Try to make the peephole optimizer smarter by maintaining
8764 an association between the assembly source code and the
8765 iCodes that originated them. Put this information to use
8766 with a new peephole rule condition "notVolatile" so that
8767 the rules can be aggressive yet still safe.
8772 * src/mcs51/peeph.def
8774 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8778 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8779 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8780 if the left or right operand symbols have the accuse flag set.
8782 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8784 Changed the type of the result of the ! (NOT) operator to char;
8785 previously it returned the same type as the source. This allows
8786 us to eliminate all the genFloatNot functions (all of its target
8787 implementations were very buggy) since !float can use the same

8799 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8800 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8801 during interrupts. Ensure WSAVE is located at a shared bank address.
8802 2. Fixed page selection in some places
8803 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8804 the registers name strings.
8805 4. Fixed "signed / unsigned compare" compiler warnings.
8806 5. The PIC port manages its own allocation of the general purpose
8807 registers, but makes no attempt to reuse them. As a result when
8808 compiling it soon runs out of general purpose registers. Some
8809 additional code was added to the files pcode.c and device.c to walk
8810 through the function call tree and rename the registers so that they
8820 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8827 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8829 Made bitfield a distinct type from bit so that bitfields
8830 convert as per ANSI C and bits retain their traditional
8831 boolean style behaviour. Implemented bitfield support in
8839 * src/ds390/gen.c: bit v bitfield split
8840 * src/z80/gen.c: New support for bitfields
8841 * support/regression/tests/bitfields.c: reenabled z80,
8844 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8846 Rules 246.x, 247.x relate to bitfields, the others speed up
8847 access to xdata mapped I/O devices.
8849 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8851 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8853 Cleaned up genPackBits and genUnpackBits and added two helper
8854 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8855 for literal assignments in genPackBits (thanks to Frieder for
8861 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8863 Fixed bug #748310 (pointer to function type mishandled when the
8864 function name is omitted). Also fixed a SIGSEGV when a function
8865 attribute (reentrant, etc) is used on a non-function or on a
8866 function but misplaced before the parameter list.
8868 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8870 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8871 * support/Util/SDCCerr.h,

8893 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8895 Made the constant following the "interrupt" keyword optional. If
8896 omitted, the function will not automatically be given an entry
8897 in the interrupt vector table (similar to #pragma NOIV, but
8898 less syntacticly kludgy). The interrupt number is also now
8899 range checked. Also fixed a bug in the high order bit example

9430 messages from optionsTable when a port is not configured, added
9431 support for the PIc16 port in the ports table, when executing
9432 the compiler with no port specified on command line, a default
9433 port is selected with the new macro DEFAULT_PORT which is
9434 defined in port.h, in setDefaultOptions() linkOptions is removed
9435 from initialization assignment, since now it is a set,
9436 parseCmdLine uses setParseWithComma for linkOptions, in
9437 linkEdit() linkOptions are accessed with new function indexSet()
9438 which returns the i'th item of a set variable. See SDCCset.c, in
9439 linkEdit() when calling buildCmdLine(), added linkOptions as
9440 last argument. Now users can pass arguments to gplink via the
9441 -Wl option, main() uses pic16glue() to glue up pic16 programs

9455 gpasm complaining and test the linkage with gplink, _linkCmd and
9456 _asmCmd changed to be more gplink and gpasm friendly
9457 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9458 produced an error when parsed, peep rule 12 is added to utilize
9459 movff, but it is commented out since the pCode does not support
9460 yet a command with 2 address arguments
9462 2003-05-18 <johan AT balder>
9464 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9491 2003-05-11 Borut Razem <borut.razem AT siol.net>
9493 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10523 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10525 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10527 * in \sdcc\as\mcs51\ changed these files in order to create an
10528 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10529 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10530 following files to include the previous two files: aslink.dsp,
10531 Makefile.aslink, Makefile.bcc, and Makefile.in.
10533 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10534 .adb instead of .cdb
10536 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10538 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10539 value from option --iram-size.
10541 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10543 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10546 2002-09-18 <wiml AT hhhh.org>
10548 * SDCClrange.h: exposed setFromRange() and setToRange()
10549 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10550 packRegsForAccUse() (bug 542397)
10551 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10552 multiple times and emitting the fetch operations more than once
10553 added aopGetUsesAcc() function to allow binary operators to
10554 fetch their operands in the correct order; made genMinus() emit
10555 compact code for X = LITERAL - Y
10557 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10558 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10559 sprintf() in line 1267.
10561 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10562 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10565 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10566 Changes to aslink (All the changes are marked with 'JCF'):
10568 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10571 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10572 area BSEG. Also moves, if possible, the DATA area down into the internal
10573 ram so more space is available.
10575 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10578 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10579 not bytes. Function summary() which creates a memory usage summary
10580 file with extension .mem. Reports of overlaping stack and small stack
10581 size. If the space for the stack is less than 16 bytes aslink trows a
10584 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10585 the 8051. Option 'y' for memory summary output file.
10587 Changes to sdcc (All the changes are marked with 'JCF'):
10589 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10591 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10592 overlaying area for it (uses RegBankUsed[4]).
10594 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10595 bank zero as used by default. By default aslink locates the stack
10596 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10597 the creation of the .mem file. Delegates the allocation of data area
10598 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10599 the begining of the stack area to aslink.
10601 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10602 glue() in SDCCglue.c creates an area for it.
10604 2002-09-03 Borut Razem <borut.razem AT siol.net>
10605 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10606 sdcc/src/pic/glue.c:
10607 introduced atexit() handler for teporay files removal in case of
10608 errors, assertions, ...
10610 2002-08-29 Borut Razem <borut.razem AT siol.net>
10611 * sdcc/support/cpp2/auto-host_vc_in.h:
10612 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10613 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10614 Maybe there is a similar problem with BORLANDC? It should be checked!
10616 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10617 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10618 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10619 was not executed, and the compiler (cl) launched a warning:
10620 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10622 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10623 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10625 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10626 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10628 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10629 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10630 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10631 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10632 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10633 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10634 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10635 - added Release configuration in VS projects
10636 - review of compiler an linker options
10637 - VC .exe files are generated in bin_vc directory, not to interfere
10638 with binaries generated from other projects (cygwin, mingw, bcc ...)
10640 * sdcc/src/yacc.dsp: added
10642 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10643 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10644 and insert the version number definitions from .version
10646 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10648 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10649 added - genarate auto-host.h using auto-host_vc_in.h as template
10652 removed from CVS, generated automatically
10654 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10655 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10657 2002-08-11 Borut Razem <borut.razem AT siol.net>
10658 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10660 2002-08-10 Borut Razem <borut.razem AT siol.net>
10661 * src/SDCCmain.c (main):
10662 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10663 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10664 The consequence was that some temporary files were not removed.
10667 unification of code in functions tempfilename() and tempfile():
10668 function tempnam() is defined in Visual Studio 6.0 and .NET
10670 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10672 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10673 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10674 - removed compiler command line option /WX: Treats all warnings as errors
10675 - update a list of source files, included into the project
10677 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10678 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10679 changed project type to Generic Project so that can be correcly converted to VS.NET project
10681 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10683 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10685 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10687 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10688 added return 0 statements after assert() to make compiler happy
10690 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10691 added newline in the def file to keep MSC compiler satisfied
10693 * sdcc/src/z80/gen.c:
10694 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10695 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10696 - solved MSC error in function aopDump()
10698 * sdcc_vc.h: define PREFIX as "\\sdcc"
10700 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10704 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10705 - Rewrote the register banking algorithm.
10706 - Added pCode live-range analysis to registers (for now, only non-used and
10707 singly-used registers optimized away)
10709 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10711 * 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.

10740 2002-03-28 Johan Knol <johan AT balder>
10742 * src/SDCCval.c: fixed bug #532436
10744 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10746 Added "char *Processor" field to the port structure.
10749 Added -p option. Allows port dependent processor to be specified.
10752 Initialized the new field char *Processor field to NULL in all ports
10755 Compiler generated registers for interrupt context saving
10756 were not getting allocated.
10758 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10761 Fixed left shift. Will promote the left side of a left shift
10762 if a) left shifting more than size of operand or b) when assigned
10763 to something size > size of left side
10765 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10767 tons of changes. Register allocation has been
10768 rewritten. Added customization for the various PICs. Flow
10769 analysis is restructured. ...
10771 * src/pic/device.h:
10774 * src/pic/device.c:
10775 Added. device.c is a PIC port hack to accomodate variations
10778 2002-03-13 Michael Hope <michaelh AT vroom>
10780 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10782 2002-03-04 johanknol <johanknol AT manik>
10784 * /src/SDCCval.c: fixed
10786 const unsigned char arr[][2] = { { 0, 1 } };

10876 Previous fix was not good. basic blocks that have "break" or "return" are
10877 not really partof a loop , but live ranges used in these blocks should
10878 be live thru the entire loop, so set partOfLoop but don't add them to
