572 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
574 Enabled VPATH feature: changed nearly all Makefiles (149 files).
575 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
577 One basic decision: e.g. src/clean.mk includes further files. In order
578 to make this work there are two solutions:
579 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
580 run configure on them. This way they can use
581 'include $(srcdir)/port-clean.mk'
582 - always include clean.mk by the Makefile at the same level. To avoid
583 that `make clean` tries to include and build Makefile.dep the
584 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
585 implemented, because now even `make uninstall` doesn't create
586 Makefile.in. clean.mk could be eliminated by pasting it in
589 * debugger/mcs51/Makefile.in: build own objects from library sources
590 (SLIB, SDCC) in current directory
592 * configure, configure.in: renamed --disable-device-lib-build in
593 --disable-device-lib; added --enable-doc, the required tools are
594 searched by configure; added result message; the toolchain for the
595 belonging ports are now only built, if the port is enabled.
597 * support/regression/*: all output is written in directory gen, because
598 the fwk and ports directories don't livet in the build tree using vpath
600 * doc/sdccman.lyx: renamed --disable-device-lib-build to
601 --disable-device-lib, added --enable-doc, added section VPATH
603 * sim/ucsim/configure.in,
604 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
605 z80 are enabled by default
607 2006-04-24 Raphael Neider <rneider AT web.de>
609 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
610 to config word, "pic14_"-prefixed some extern functions
611 (pic14_emitConfigWord): emit __config directive(s) if assignment to
612 config word has been found
613 * src/pic/device.h: added prototypes
614 * src/pic/pcode.c: added "pic14_"-prefix where needed

904 linking is done manually in pic16 port's _linkEdit,
905 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
906 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

923 call to allocReg, not by manually allocating a new one,
924 (pic16_assignRegisters): now before going through the register
925 allocating functions mark all registers as free. This eliminates some
926 side effects resulting from peephole parser done earlier in the backbone

949 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
950 (aopForSym, aopOp): increment asmop.allocated if reused,
951 (freeAsmop): decrement asmop.allocated and check for zero instead of
953 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
954 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
955 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

961 in reverse order from allocation,
962 (genPlus, genCmpEq): free asmop's in reverse order from allocation and
963 added swappedLR to keep track

976 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
978 2006-03-06 Borut Razem <borut.razem AT siol.net>
980 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
981 made the linker quiet
983 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
985 * src/pic16/gen.c (genPcall): fixed bug #1443644
986 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
987 which dumps before the function entry point a data byte which represents
988 the number of the local variables used by the specified function, added
989 'xinst' for initial support for Extended Instruction Support,
990 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
991 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
992 port->fun_prefix anymore (may change later),
993 (genFunction, genEndFunction): do not store/restore local registers for
994 _main (this should take care the --main-return command line option in
996 (genOr): removed some legacy pic-port instructions,
997 * src/pic16/genarith.c (genAddLit): re-enabled old code because
998 performing operations with SFR's causes data to be written more than
999 once to each SFR. Perhaps SFRs should be handled in special cases...
1000 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1002 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1005 --extended or -y for Extended Instruction Support,
1006 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1007 (deassignLRs): *** perhaps the most important change, old 'for' code
1008 (commented out for reference), didn't account for some registers which
1009 were left marked 'not free' after a pointer operation. The change
1010 reduces register usage a lot in some cases

3283 * src/SDCCglobal.h (struct options),
3285 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3286 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3287 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3288 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3289 always available in leading double underscore form. The C99 support is
3290 mostly missing, but it's a start.
3291 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3292 reserved identifier "__data".
3294 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3368 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3370 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3372 * device/lib/printf_large.c: removed inline assembly for portability and
3373 readability. Use printf_fast if speed or size are more important.
3374 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3375 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3377 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3379 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3380 prevent compiler warning
3382 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3384 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3385 moved to level 0 and declared as static. Also they are explicit
3386 placed in access bank. This was necessery because some times they
3387 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3388 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3389 optimizations. Currently only compare to unsigned char is implemented,
3390 * src/pic16/gen.c: added fReturnIdx array,
3391 * (struct resolvedIfx) is moved to gen.h and made public,
3392 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3393 * (aopForSym): added an optimization to directly store in stack of
3394 the operand of a SEND iCode,
3395 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3396 but as registers instead (AOP_REG) using the fReturnIdx array,
3397 * (pic16_freeAsmop): remove the freed register from the
3398 _G.sregsAlloc field,
3399 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3400 a compare of 'WREG',
3401 * (pic16_popGetTempRegCond): changed function prototype, now
3402 function takes also a bitVector argument v which holds the current
3403 set of registers that are allocated for stack access by aopForSym,
3404 registers allocated in aopForSym for accessing stack symbols are not
3405 any more part of the functions usedRegs field,
3406 * (genCall): some times aopOp is called for a stack variable to be
3407 send, aopForSym might perform the push, if this is true make sure
3408 that genCall doesn't push the variable twice by testing _G.resDirect,
3409 * (genFunction): changed testing for unspecified interrupt number
3410 from 256 to INTNO_UNSPEC,
3411 * modified selection scheme of frame pointer generation. Previously
3412 if function did use local registers a frame pointer was generated,
3413 now a frame pointer is generated only if function has arguments
3414 (that need PLUSW2 register access), or has stack arguments, or the
3415 compiler is not instructed to omit the frame pointer,
3416 * (genEndFunction): before restoring local registers that were saved
3417 in the function preamble, also restore the registers that *might*
3418 have been allocated for stack access,
3419 * (genRet): removed some old comments,
3420 * (genCmp, the active (RN's) version): added a call to the
3421 pic16_genCmp_special function to perform the compare with a more
3422 robust and optimized way,
3423 * (genInline): a feature has been added in inline code generation,
3424 which allows a wildcard variable substitution when writing inline
3425 assembly. Code is incomplete and experimental therefore undocumented,
3426 * (genCast): changed order of aopOp for result and right to allow
3427 aopForSym to directly load the result if possible,
3428 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3429 perform an optimized compare on some selected special occasions,
3430 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3431 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3432 generate an IVT any more,
3433 * src/pic16/main.c (pic16_optionsTable): added command line option
3435 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3436 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3438 * src/pic16/NOTES: Raphael Neider added in list of active developers
3439 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3440 jumptable_end to prevent bug #,
3441 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3442 inCond and outCond fields,
3443 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3444 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3445 turn off register spilling,
3446 * (packRegsForOneUse): synced with other ports' versions although it
3447 is not used currently,
3448 * (pic16_packRegisters): added an optimization while reading
3449 structure bitfields, some registers may be saved (malloc code is
3450 decreased by 80 bytes)
3452 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3454 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3455 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3456 this can be optimized more?
3458 2005-03-10 Raphael Neider <rneider AT web.de>
3460 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3461 genNearPointerGet): (hopefully) fixed access to bitfields via
3462 pointers (p->bitN = x; and x = p->bitN; failed)
3464 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3466 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3468 2005-03-09 Raphael Neider <rneider AT web.de>
3470 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
3472 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3474 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC

4096 Adding support for replacing ljmps with sjmps in jumptables
4097 generated for switch statements. For now you need to set the
4098 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4099 Now 4 algorithms for mcs51 jumptable generation are used:
4100 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4101 addresses loaded pc-relative for up to 112 cases and stack-pushing
4102 target addresses loaded with offset from dptr for up to 256 cases.

4132 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4134 * added libc directory. The current version of LibC contains string
4135 functions, ctype functions and macros and some functions of the
4136 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4137 be extensively tested in the future. Standard disclaimer here.
4138 Library is not automatically build yet. But one can build it by
4139 invoking 'make' inside the libc directory.

4150 * (pic16_storeForReturn): optimized return of 0,
4151 * (genCmp): experimental code for new genCmp which uses PIC18's
4152 special compare&skip instructions. Initial tests fail some times
4153 with variables grater than 1 byte in size, so new code is disabled,
4154 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4156 * (genCast): began a fix to optimize the casting of a bit to another
4157 bit, now assigning a bitfield to another bitfield will fail, sorry,
4158 * src/pic16/main.c: disabled the use of lr-support feature,
4159 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4166 and 1 for banking instruction,
4167 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4168 caused stop processing pCodes after a inline assembly block,
4169 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4170 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4171 registers when it shouldn't,
4172 * src/pic16/ralloc.c (allocReg): add preliminary support for
4173 supporting a limited set of temporary registers,
4175 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4181 (genFunction): optimize RECEIVE iCodes in reentrant functions
4183 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4185 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7183 loaded with the linker search paths (-L arguments) and the libraries
7184 to be linked with the current source (-l arguments). Changes
7185 currently will affect only the pic16 port.
7186 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7187 include path the port specific paths and port specific libraries,
7188 * gplink command now contains the $3 argument,

7206 Documenting changes from previous commits.
7207 * configure.in (version 1.56),
7208 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7209 when generating output files to configure the pic16 library,
7210 but now I've commented it out, since gputils aren't installed in the
7211 SF compile farm, so library won't compile
7213 * device/lib/Makefile.in (version 1.56): initially I've added in
7214 target 'all' the prerequestive 'model-pic16' so it compiled the
7215 pic16 library, but now I've commented it out for the same reasons
7217 * added targets 'model-pic16' and 'objects-pic16' to compile the
7219 * added target 'port-specific-objects-pic16' to handle the
7220 generated libraries and copy them into the build/ directory
7221 * added target 'clean-intermediate-pic16' to clean intermediate
7222 files into pic16 directory
7223 * in target 'installdirs' added line to create directory pic16 in

7488 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7489 * src/SDCCsymt.c (newEnumType),
7491 * support/Util/SDCCerr.c,
7492 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7494 * support/regression/tests/enum.c: added test for enum values that
7495 require at least 2 bytes of storage.
7497 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7499 * src/common.h: added ifndef/define/endif macros
7500 around the header file.
7501 Bug reported from Jesus Calvino-Fraga
7503 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7505 * sdcc.spec: updated
7506 * device/include/Makefile.in: don't install CVS directories
7507 * device/lib/Makefile.in: added removal of CVS directories after install
7508 * doc/Makefile: fixed install, added local_icons
7509 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7510 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7511 * src/ds390/gen.c (genRightShift): fixed bug #870788
7512 * src/SDCCast.c (decorateType): fixed bug #870781
7514 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7516 PIC16 port related changes:
7517 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7518 added variable stackPos,
7520 * gen.c: genCall, assignResultValue: added support for
7521 pushing/retrieving function parameters to/from stack,
7522 genFunction,genEndFunction: setup stack frame for the
7524 genAddrOf: will be changed according to bug 863624
7526 * added files genutils.c and genutils.h which contain gen*
7527 debugged and optimised functions extracted from gen.c
7529 * glue.c: added variable 'externs' which holds extern symbols,
7530 pic16emitRegularMap: is modified to properly handle relocatable
7531 symbols under the new scheme,
7532 pic16createInterruptVect: is modified
7533 pic16printPublics: is modified to emit 'global' assembler directives,
7534 added pic16_printExterns to print extern symbols,
7535 pic16glue: initializes stack/frame pointer in the beginning of
7536 the assembly output. Temporary hack, will be corrected later,
7537 because gplink yet does not support stack and SDCC does not
7538 yet support a type of crt0.o object to create the final binary.
7540 * Removed many lines that contain 8051 legacy code.
7541 * The code is finally placed under a 'code' directive.
7542 * Added port specific options.
7544 * _process_pragma: simplified since now we do not need *special*
7545 include file to define SFR registers. But a separate header
7546 will be needed. This will be developed later.
7547 * _pic16_parseOptions: added, parses port specific options:
7548 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7549 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7550 --preplace-udata-with=
7552 * _pic16_setDefaultOptions: modified to initialize section names,
7553 but hack is temporarly out of order since it needs improvement.
7554 * _pic16_genAssemblerPreamble: configuration words are emitted by
7555 their address instead of their name. This part is incomplete and
7556 supports only the 18Fxx2 devices. Other devices will emit an error
7557 during assembly since they do not contain the same set of config
7559 * _pic16_genIVT: is modified,
7561 * pcode.c: added definitions for some hardware registers that are needed
7563 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7564 All PCI entries are updated. Now LFSR is supported.
7565 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7566 * added pic16_newpCodeOpLit2 to support instructions with
7567 two literal arguments
7568 * pic16_pCode2str: corrected code that emits assembler instructions
7569 with two literal operands and those that have an access bit modifier
7570 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7571 this fixes a bug which caused some labels to be lost, when an
7572 assembler directive was added, i.e. banksel,
7573 * pic16_FixRegisterBanking: improved logic that causes the insertion
7575 * InlineFunction: functions that are called once, are not any more
7576 inlined. This can be a port option in the future,
7578 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7580 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7581 hold the corresponding uninitialized symbols,
7582 * pic16_allocProcessorRegister: registers have explicit marked the
7584 * pic16_allocInternalRegister: registers are explicit marked as
7586 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7587 processing list, so bit registers were lost,
7590 * ralloc.h: added field 'accessBank' and original symbol operand
7591 in register definition,
7592 * removed the field isMapped from register definition,
7594 ** Several functions have been removed from various sources:
7595 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7596 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7597 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7598 pic16_assignRelocatableRegisters
7600 ** others have been introduced:
7601 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7602 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7604 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7606 * support/scripts/inc2h.pl: changed definition of BIT_AT
7607 to emit 'sbit at' instead of 'bit at'. This was a request.
7609 PIC16 port related preliminary changes:
7610 * gen.c: prefixed function popRegFromString with
7611 pic16_ and all references to it corrected
7612 * pcode.c: all pic16_pc_* hardware registers prefixed
7613 with underscore (_),
7614 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7615 * ralloc.c: newReg(): when register is REG_SFR then
7616 set address to rIdx,
7617 pic16_allocProcessorRegister(): marks register wasUsed=0
7618 pic16_writeUsedRegs(): added a call to assign processor
7619 registers via pic16_assignFixedRegisters
7621 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7623 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7624 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7625 variables in unused register banks. Also the SSEG is placed
7626 wherever there is enough space for it, and IDATA can be anywhere
7627 in internal RAM. For now compile using -Wl-Y[stack_size].
7628 The mem file is different for this option as well, since it
7629 makes no sense of talking about DSEG lenght.
7631 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7633 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7634 in certain cases, e.g. when ROM assignment, patch provided
7635 from Albert den Haan.

7876 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7878 * src/SDCCast.c (decorateType): disabled a transformation I added in
7879 revision 1.188 (access to fields of a structure at an absolute address);
7880 it breaks with bitfields, extern declarations, and gcse analysis.
7881 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7882 could be assigned through a pointer, so don't complain.
7883 * src/SDCCast.c (astErrors),
7885 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8639 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8640 fetching of the pointer
8641 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8642 copied from genNearPointerSet()
8643 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8644 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8658 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8660 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8661 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8662 type for bits was changed. It resulted in bit variables becoming
8663 global, which is not permitted in PIC 14 assembly output.
8665 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8667 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8680 A few small changes that speed up the peephole optimizer.
8684 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8686 Try to make the peephole optimizer smarter by maintaining
8687 an association between the assembly source code and the
8688 iCodes that originated them. Put this information to use
8689 with a new peephole rule condition "notVolatile" so that
8690 the rules can be aggressive yet still safe.
8695 * src/mcs51/peeph.def
8697 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8701 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8702 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8703 if the left or right operand symbols have the accuse flag set.
8705 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8707 Changed the type of the result of the ! (NOT) operator to char;
8708 previously it returned the same type as the source. This allows
8709 us to eliminate all the genFloatNot functions (all of its target
8710 implementations were very buggy) since !float can use the same
8713 * src/SDCCicode.c (ast2iCode): ! returns char

8722 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8723 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8724 during interrupts. Ensure WSAVE is located at a shared bank address.
8725 2. Fixed page selection in some places
8726 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8727 the registers name strings.
8728 4. Fixed "signed / unsigned compare" compiler warnings.
8729 5. The PIC port manages its own allocation of the general purpose
8730 registers, but makes no attempt to reuse them. As a result when
8731 compiling it soon runs out of general purpose registers. Some
8732 additional code was added to the files pcode.c and device.c to walk
8733 through the function call tree and rename the registers so that they
8743 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8744 genPlus() & genMinus() when the result is the same as left or right

8750 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8752 Made bitfield a distinct type from bit so that bitfields
8753 convert as per ANSI C and bits retain their traditional
8754 boolean style behaviour. Implemented bitfield support in
8762 * src/ds390/gen.c: bit v bitfield split
8763 * src/z80/gen.c: New support for bitfields
8764 * support/regression/tests/bitfields.c: reenabled z80,
8767 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8769 Rules 246.x, 247.x relate to bitfields, the others speed up
8770 access to xdata mapped I/O devices.
8772 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8774 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8776 Cleaned up genPackBits and genUnpackBits and added two helper
8777 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8778 for literal assignments in genPackBits (thanks to Frieder for
8784 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8786 Fixed bug #748310 (pointer to function type mishandled when the
8787 function name is omitted). Also fixed a SIGSEGV when a function
8788 attribute (reentrant, etc) is used on a non-function or on a
8789 function but misplaced before the parameter list.
8791 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8793 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8794 * support/Util/SDCCerr.h,

8816 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8818 Made the constant following the "interrupt" keyword optional. If
8819 omitted, the function will not automatically be given an entry
8820 in the interrupt vector table (similar to #pragma NOIV, but
8821 less syntacticly kludgy). The interrupt number is also now
8822 range checked. Also fixed a bug in the high order bit example

8836 * src/SDCCicode.c (operandOperation): rewritten some ops
8837 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8838 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8840 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8841 be re-activated by defining REDUCE_LITERALS)
8842 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8843 unsigned, but are signed by default
8844 * src/SDCCval.c (constVal): rearranged
8845 * src/SDCCval.c (valMod): preliminary fix
8846 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9352 added if/endif conditional macros to remove options help
9353 messages from optionsTable when a port is not configured, added
9354 support for the PIc16 port in the ports table, when executing
9355 the compiler with no port specified on command line, a default
9356 port is selected with the new macro DEFAULT_PORT which is
9357 defined in port.h, in setDefaultOptions() linkOptions is removed
9358 from initialization assignment, since now it is a set,
9359 parseCmdLine uses setParseWithComma for linkOptions, in
9360 linkEdit() linkOptions are accessed with new function indexSet()
9361 which returns the i'th item of a set variable. See SDCCset.c, in
9362 linkEdit() when calling buildCmdLine(), added linkOptions as
9363 last argument. Now users can pass arguments to gplink via the
9364 -Wl option, main() uses pic16glue() to glue up pic16 programs

9378 gpasm complaining and test the linkage with gplink, _linkCmd and
9379 _asmCmd changed to be more gplink and gpasm friendly
9380 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9381 produced an error when parsed, peep rule 12 is added to utilize
9382 movff, but it is commented out since the pCode does not support
9383 yet a command with 2 address arguments
9385 2003-05-18 <johan AT balder>
9387 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9414 2003-05-11 Borut Razem <borut.razem AT siol.net>
9416 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10409 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10410 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10411 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10412 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10413 * src/pic/pcode.c: outcommented unused variable to remove warnings

10420 2003-01-06 <johan AT balder>
10422 * src/SDCCicode.c: fixed array add
10424 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10425 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10426 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10428 2003-01-04 <johan AT balder>
10430 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10432 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10433 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10435 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10436 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10437 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10439 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10440 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10442 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10443 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10445 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10446 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10448 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10450 * in \sdcc\as\mcs51\ changed these files in order to create an
10451 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10452 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10453 following files to include the previous two files: aslink.dsp,
10454 Makefile.aslink, Makefile.bcc, and Makefile.in.
10456 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10457 .adb instead of .cdb
10459 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10461 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10462 value from option --iram-size.
10464 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10466 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10469 2002-09-18 <wiml AT hhhh.org>
10471 * SDCClrange.h: exposed setFromRange() and setToRange()
10472 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10473 packRegsForAccUse() (bug 542397)
10474 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10475 multiple times and emitting the fetch operations more than once
10476 added aopGetUsesAcc() function to allow binary operators to
10477 fetch their operands in the correct order; made genMinus() emit
10478 compact code for X = LITERAL - Y
10480 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10481 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10482 sprintf() in line 1267.
10484 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10485 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10488 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10489 Changes to aslink (All the changes are marked with 'JCF'):
10491 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10494 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10495 area BSEG. Also moves, if possible, the DATA area down into the internal
10496 ram so more space is available.
10498 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10501 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10502 not bytes. Function summary() which creates a memory usage summary
10503 file with extension .mem. Reports of overlaping stack and small stack
10504 size. If the space for the stack is less than 16 bytes aslink trows a
10507 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10508 the 8051. Option 'y' for memory summary output file.
10510 Changes to sdcc (All the changes are marked with 'JCF'):
10512 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10514 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10515 overlaying area for it (uses RegBankUsed[4]).
10517 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10518 bank zero as used by default. By default aslink locates the stack
10519 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10520 the creation of the .mem file. Delegates the allocation of data area
10521 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10522 the begining of the stack area to aslink.
10524 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10525 glue() in SDCCglue.c creates an area for it.
10527 2002-09-03 Borut Razem <borut.razem AT siol.net>
10528 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10529 sdcc/src/pic/glue.c:
10530 introduced atexit() handler for teporay files removal in case of
10531 errors, assertions, ...
10533 2002-08-29 Borut Razem <borut.razem AT siol.net>
10534 * sdcc/support/cpp2/auto-host_vc_in.h:
10535 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10536 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10537 Maybe there is a similar problem with BORLANDC? It should be checked!
10539 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10540 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10541 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10542 was not executed, and the compiler (cl) launched a warning:
10543 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10545 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10546 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10548 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10549 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10551 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10552 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10553 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10554 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10555 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10556 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10557 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10558 - added Release configuration in VS projects
10559 - review of compiler an linker options
10560 - VC .exe files are generated in bin_vc directory, not to interfere
10561 with binaries generated from other projects (cygwin, mingw, bcc ...)
10563 * sdcc/src/yacc.dsp: added
10565 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10566 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10567 and insert the version number definitions from .version
10569 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10571 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10572 added - genarate auto-host.h using auto-host_vc_in.h as template
10575 removed from CVS, generated automatically
10577 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10578 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10580 2002-08-11 Borut Razem <borut.razem AT siol.net>
10581 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10583 2002-08-10 Borut Razem <borut.razem AT siol.net>
10584 * src/SDCCmain.c (main):
10585 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10586 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10587 The consequence was that some temporary files were not removed.
10590 unification of code in functions tempfilename() and tempfile():
10591 function tempnam() is defined in Visual Studio 6.0 and .NET
10593 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10595 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10596 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10597 - removed compiler command line option /WX: Treats all warnings as errors
10598 - update a list of source files, included into the project
10600 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10601 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10602 changed project type to Generic Project so that can be correcly converted to VS.NET project
10604 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10606 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10608 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10610 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10611 added return 0 statements after assert() to make compiler happy
10613 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10614 added newline in the def file to keep MSC compiler satisfied
10616 * sdcc/src/z80/gen.c:
10617 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10618 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10619 - solved MSC error in function aopDump()
10621 * sdcc_vc.h: define PREFIX as "\\sdcc"
10623 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10624 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10659 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10661 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10663 2002-03-28 Johan Knol <johan AT balder>
10665 * src/SDCCval.c: fixed bug #532436
10667 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10669 Added "char *Processor" field to the port structure.
10672 Added -p option. Allows port dependent processor to be specified.
10675 Initialized the new field char *Processor field to NULL in all ports
10678 Compiler generated registers for interrupt context saving
10679 were not getting allocated.
10681 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10684 Fixed left shift. Will promote the left side of a left shift
10685 if a) left shifting more than size of operand or b) when assigned
10686 to something size > size of left side
10688 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10690 tons of changes. Register allocation has been

10692 analysis is restructured. ...
10694 * src/pic/device.h:
10697 * src/pic/device.c:
10698 Added. device.c is a PIC port hack to accomodate variations
10701 2002-03-13 Michael Hope <michaelh AT vroom>
10703 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10705 2002-03-04 johanknol <johanknol AT manik>
10707 * /src/SDCCval.c: fixed
10709 const unsigned char arr[][2] = { { 0, 1 } };

10796 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10798 * sdcc/src/SDCCloop.c:
10799 Previous fix was not good. basic blocks that have "break" or "return" are
10800 not really partof a loop , but live ranges used in these blocks should
10801 be live thru the entire loop, so set partOfLoop but don't add them to
10804 2002-02-21 <johan AT FRIJA>
10806 * src/SDCCcse.c: fixed bug #514308
10808 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10811 Fixed BUG #519583. If a conditional block ended in a return/break
10812 statement inside a loop, it was not being considered part of the loop.
10814 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10816 2002-02-10 Karl Bongers <karl AT turbobit.com>

10827 for use as a multiple module SDCDB test case.
10829 * sim/ucsim/cmd.src/cmdset.cc:
10830 Took out debug printfs in ucsim "next" command.
10832 * sim/ucsim/xa.src:
10833 Karl and Johan start ucsim XA support. Most dissassembly working,
10834 about 75% emulation done(plenty of work remaining).
10836 * sim/ucsim/z80.src:
10837 Add Z80 support to ucsim, add test-ucz80 regression test,
10838 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10839 Notice z80 compiler fails on examples/test3.c/crc code.
10841 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10843 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10851 from a memory mapped port
10852 2) added __builtin_memcmp
10853 3) added __builtin_swapw swap bytes of a short
10855 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10856 1) handle multiple send & receives from register bank1
10857 2) ralloc can now allocate DPTR1 to some liveRanges
10859 * src/SDCCsymt.c, src/SDCCsymt.h:
10860 changes to handle multiple sends & receives
10862 * src/SDCCptropt.h:
10863 added some pointer arithmetic optimization
10865 * src/SDCCptropt.c:
