530 Enabled VPATH feature: changed nearly all Makefiles (149 files).
531 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
533 One basic decision: e.g. src/clean.mk includes further files. In order
534 to make this work there are two solutions:
535 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
536 run configure on them. This way they can use
537 'include $(srcdir)/port-clean.mk'
538 - always include clean.mk by the Makefile at the same level. To avoid
539 that `make clean` tries to include and build Makefile.dep the
540 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
541 implemented, because now even `make uninstall` doesn't create
542 Makefile.in. clean.mk could be eliminated by pasting it in
545 * debugger/mcs51/Makefile.in: build own objects from library sources
546 (SLIB, SDCC) in current directory
548 * configure, configure.in: renamed --disable-device-lib-build in
549 --disable-device-lib; added --enable-doc, the required tools are
550 searched by configure; added result message; the toolchain for the
551 belonging ports are now only built, if the port is enabled.
553 * support/regression/*: all output is written in directory gen, because
554 the fwk and ports directories don't livet in the build tree using vpath
556 * doc/sdccman.lyx: renamed --disable-device-lib-build to
557 --disable-device-lib, added --enable-doc, added section VPATH
559 * sim/ucsim/configure.in,
560 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
561 z80 are enabled by default
563 2006-04-24 Raphael Neider <rneider AT web.de>
565 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
566 to config word, "pic14_"-prefixed some extern functions
567 (pic14_emitConfigWord): emit __config directive(s) if assignment to
568 config word has been found
569 * src/pic/device.h: added prototypes
570 * src/pic/pcode.c: added "pic14_"-prefix where needed

587 fixes #1469504 and #1474602,
588 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

931 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
932 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
934 2006-03-06 Borut Razem <borut.razem AT siol.net>
936 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
937 made the linker quiet
939 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
941 * src/pic16/gen.c (genPcall): fixed bug #1443644
942 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
943 which dumps before the function entry point a data byte which represents
944 the number of the local variables used by the specified function, added
945 'xinst' for initial support for Extended Instruction Support,
946 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
947 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
948 port->fun_prefix anymore (may change later),
949 (genFunction, genEndFunction): do not store/restore local registers for
950 _main (this should take care the --main-return command line option in
952 (genOr): removed some legacy pic-port instructions,
953 * src/pic16/genarith.c (genAddLit): re-enabled old code because
954 performing operations with SFR's causes data to be written more than
955 once to each SFR. Perhaps SFRs should be handled in special cases...
956 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
958 * src/pic16/main.c (_process_pragma): stack bound checking did not take
959 into account for stack starting position,
960 (struct OPTIONS pic16_optionsTable): added command line argument
961 --extended or -y for Extended Instruction Support,
962 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
963 (deassignLRs): *** perhaps the most important change, old 'for' code
964 (commented out for reference), didn't account for some registers which
965 were left marked 'not free' after a pointer operation. The change
966 reduces register usage a lot in some cases

3239 * src/SDCCglobal.h (struct options),
3241 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3242 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3243 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3244 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3245 always available in leading double underscore form. The C99 support is
3246 mostly missing, but it's a start.
3247 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3248 reserved identifier "__data".

3326 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3328 * device/lib/printf_large.c: removed inline assembly for portability and
3329 readability. Use printf_fast if speed or size are more important.
3330 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3331 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3333 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3335 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3336 prevent compiler warning
3338 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3340 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3341 moved to level 0 and declared as static. Also they are explicit
3342 placed in access bank. This was necessery because some times they
3343 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3344 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3345 optimizations. Currently only compare to unsigned char is implemented,
3346 * src/pic16/gen.c: added fReturnIdx array,
3347 * (struct resolvedIfx) is moved to gen.h and made public,
3348 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3349 * (aopForSym): added an optimization to directly store in stack of
3350 the operand of a SEND iCode,
3351 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3352 but as registers instead (AOP_REG) using the fReturnIdx array,
3353 * (pic16_freeAsmop): remove the freed register from the
3354 _G.sregsAlloc field,
3355 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3356 a compare of 'WREG',
3357 * (pic16_popGetTempRegCond): changed function prototype, now
3358 function takes also a bitVector argument v which holds the current
3359 set of registers that are allocated for stack access by aopForSym,
3360 registers allocated in aopForSym for accessing stack symbols are not
3361 any more part of the functions usedRegs field,
3362 * (genCall): some times aopOp is called for a stack variable to be
3363 send, aopForSym might perform the push, if this is true make sure
3364 that genCall doesn't push the variable twice by testing _G.resDirect,
3365 * (genFunction): changed testing for unspecified interrupt number
3366 from 256 to INTNO_UNSPEC,
3367 * modified selection scheme of frame pointer generation. Previously
3368 if function did use local registers a frame pointer was generated,
3369 now a frame pointer is generated only if function has arguments
3370 (that need PLUSW2 register access), or has stack arguments, or the
3371 compiler is not instructed to omit the frame pointer,
3372 * (genEndFunction): before restoring local registers that were saved
3373 in the function preamble, also restore the registers that *might*
3374 have been allocated for stack access,
3375 * (genRet): removed some old comments,
3376 * (genCmp, the active (RN's) version): added a call to the
3377 pic16_genCmp_special function to perform the compare with a more
3378 robust and optimized way,
3379 * (genInline): a feature has been added in inline code generation,
3380 which allows a wildcard variable substitution when writing inline
3381 assembly. Code is incomplete and experimental therefore undocumented,
3382 * (genCast): changed order of aopOp for result and right to allow
3383 aopForSym to directly load the result if possible,
3384 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3385 perform an optimized compare on some selected special occasions,
3386 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3387 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3388 generate an IVT any more,
3389 * src/pic16/main.c (pic16_optionsTable): added command line option
3391 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3392 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3394 * src/pic16/NOTES: Raphael Neider added in list of active developers
3395 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3396 jumptable_end to prevent bug #,
3397 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3398 inCond and outCond fields,
3399 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3400 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3401 turn off register spilling,
3402 * (packRegsForOneUse): synced with other ports' versions although it
3403 is not used currently,
3404 * (pic16_packRegisters): added an optimization while reading
3405 structure bitfields, some registers may be saved (malloc code is
3406 decreased by 80 bytes)
3408 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3410 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3411 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3412 this can be optimized more?
3414 2005-03-10 Raphael Neider <rneider AT web.de>
3416 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3417 genNearPointerGet): (hopefully) fixed access to bitfields via
3418 pointers (p->bitN = x; and x = p->bitN; failed)
3420 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3422 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4052 Adding support for replacing ljmps with sjmps in jumptables
4053 generated for switch statements. For now you need to set the
4054 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4055 Now 4 algorithms for mcs51 jumptable generation are used:
4056 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4057 addresses loaded pc-relative for up to 112 cases and stack-pushing
4058 target addresses loaded with offset from dptr for up to 256 cases.

4088 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4090 * added libc directory. The current version of LibC contains string
4091 functions, ctype functions and macros and some functions of the
4092 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4093 be extensively tested in the future. Standard disclaimer here.
4094 Library is not automatically build yet. But one can build it by
4095 invoking 'make' inside the libc directory.

4106 * (pic16_storeForReturn): optimized return of 0,
4107 * (genCmp): experimental code for new genCmp which uses PIC18's
4108 special compare&skip instructions. Initial tests fail some times
4109 with variables grater than 1 byte in size, so new code is disabled,
4110 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4112 * (genCast): began a fix to optimize the casting of a bit to another
4113 bit, now assigning a bitfield to another bitfield will fail, sorry,
4114 * src/pic16/main.c: disabled the use of lr-support feature,
4115 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4121 * (isBankInstruction): modified to return 0 for no banking instruction,
4122 and 1 for banking instruction,
4123 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4124 caused stop processing pCodes after a inline assembly block,
4125 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4126 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4127 registers when it shouldn't,
4128 * src/pic16/ralloc.c (allocReg): add preliminary support for
4129 supporting a limited set of temporary registers,
4131 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4133 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4134 genDataPointerSet): ensure assignments always copy in MSB to LSB
4136 (loadRegFromAop): recognize CLRH optimization,
4137 (genFunction): optimize RECEIVE iCodes in reentrant functions
4139 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4141 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7139 loaded with the linker search paths (-L arguments) and the libraries
7140 to be linked with the current source (-l arguments). Changes
7141 currently will affect only the pic16 port.
7142 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7143 include path the port specific paths and port specific libraries,
7144 * gplink command now contains the $3 argument,
7145 * src/pic16/device.h,

7162 Documenting changes from previous commits.
7163 * configure.in (version 1.56),
7164 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7165 when generating output files to configure the pic16 library,
7166 but now I've commented it out, since gputils aren't installed in the
7167 SF compile farm, so library won't compile
7169 * device/lib/Makefile.in (version 1.56): initially I've added in
7170 target 'all' the prerequestive 'model-pic16' so it compiled the
7171 pic16 library, but now I've commented it out for the same reasons
7173 * added targets 'model-pic16' and 'objects-pic16' to compile the
7175 * added target 'port-specific-objects-pic16' to handle the
7176 generated libraries and copy them into the build/ directory
7177 * added target 'clean-intermediate-pic16' to clean intermediate
7178 files into pic16 directory
7179 * in target 'installdirs' added line to create directory pic16 in

7472 PIC16 port related changes:
7473 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7474 added variable stackPos,
7476 * gen.c: genCall, assignResultValue: added support for
7477 pushing/retrieving function parameters to/from stack,
7478 genFunction,genEndFunction: setup stack frame for the
7480 genAddrOf: will be changed according to bug 863624
7482 * added files genutils.c and genutils.h which contain gen*
7483 debugged and optimised functions extracted from gen.c
7485 * glue.c: added variable 'externs' which holds extern symbols,
7486 pic16emitRegularMap: is modified to properly handle relocatable
7487 symbols under the new scheme,
7488 pic16createInterruptVect: is modified
7489 pic16printPublics: is modified to emit 'global' assembler directives,
7490 added pic16_printExterns to print extern symbols,
7491 pic16glue: initializes stack/frame pointer in the beginning of
7492 the assembly output. Temporary hack, will be corrected later,
7493 because gplink yet does not support stack and SDCC does not
7494 yet support a type of crt0.o object to create the final binary.
7496 * Removed many lines that contain 8051 legacy code.
7497 * The code is finally placed under a 'code' directive.
7498 * Added port specific options.
7500 * _process_pragma: simplified since now we do not need *special*
7501 include file to define SFR registers. But a separate header
7502 will be needed. This will be developed later.
7503 * _pic16_parseOptions: added, parses port specific options:
7504 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7505 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7506 --preplace-udata-with=
7508 * _pic16_setDefaultOptions: modified to initialize section names,
7509 but hack is temporarly out of order since it needs improvement.
7510 * _pic16_genAssemblerPreamble: configuration words are emitted by
7511 their address instead of their name. This part is incomplete and
7512 supports only the 18Fxx2 devices. Other devices will emit an error
7513 during assembly since they do not contain the same set of config
7515 * _pic16_genIVT: is modified,
7517 * pcode.c: added definitions for some hardware registers that are needed
7519 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7520 All PCI entries are updated. Now LFSR is supported.
7521 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7522 * added pic16_newpCodeOpLit2 to support instructions with
7523 two literal arguments
7524 * pic16_pCode2str: corrected code that emits assembler instructions
7525 with two literal operands and those that have an access bit modifier
7526 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7527 this fixes a bug which caused some labels to be lost, when an
7528 assembler directive was added, i.e. banksel,
7529 * pic16_FixRegisterBanking: improved logic that causes the insertion
7531 * InlineFunction: functions that are called once, are not any more
7532 inlined. This can be a port option in the future,
7534 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7536 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7537 hold the corresponding uninitialized symbols,
7538 * pic16_allocProcessorRegister: registers have explicit marked the
7540 * pic16_allocInternalRegister: registers are explicit marked as
7542 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7543 processing list, so bit registers were lost,
7546 * ralloc.h: added field 'accessBank' and original symbol operand
7547 in register definition,
7548 * removed the field isMapped from register definition,
7550 ** Several functions have been removed from various sources:
7551 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7552 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7553 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7554 pic16_assignRelocatableRegisters
7556 ** others have been introduced:
7557 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7558 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7560 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7562 * support/scripts/inc2h.pl: changed definition of BIT_AT
7563 to emit 'sbit at' instead of 'bit at'. This was a request.
7565 PIC16 port related preliminary changes:
7566 * gen.c: prefixed function popRegFromString with
7567 pic16_ and all references to it corrected
7568 * pcode.c: all pic16_pc_* hardware registers prefixed
7569 with underscore (_),
7570 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7571 * ralloc.c: newReg(): when register is REG_SFR then
7572 set address to rIdx,
7573 pic16_allocProcessorRegister(): marks register wasUsed=0
7574 pic16_writeUsedRegs(): added a call to assign processor
7575 registers via pic16_assignFixedRegisters
7577 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7579 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7580 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7581 variables in unused register banks. Also the SSEG is placed
7582 wherever there is enough space for it, and IDATA can be anywhere
7583 in internal RAM. For now compile using -Wl-Y[stack_size].
7584 The mem file is different for this option as well, since it
7585 makes no sense of talking about DSEG lenght.
7587 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7589 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7590 in certain cases, e.g. when ROM assignment, patch provided
7591 from Albert den Haan.
7593 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7834 * src/SDCCast.c (decorateType): disabled a transformation I added in
7835 revision 1.188 (access to fields of a structure at an absolute address);
7836 it breaks with bitfields, extern declarations, and gcse analysis.
7837 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7838 could be assigned through a pointer, so don't complain.
7839 * src/SDCCast.c (astErrors),
7841 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8479 support for standard C idiom of memory mapped variables; for
8480 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8481 to xdata int at 0x1234 tempvar = 1.
8482 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8483 provided by Akiya ISHIDA

8499 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8501 Fixed bug #621531 (const & volatile confusion in the type chain).
8502 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8503 refer to the const or volatile state of the pointer itself.

8568 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8569 pcoderegs.h, ralloc.c, ralloc.h
8570 * main.c: added top header and GPL license notice

8594 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8595 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8596 fetching of the pointer
8597 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8598 copied from genNearPointerSet()
8599 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8600 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8601 If they pop r0/r1 they must be called in the opposite order than aopOp().
8602 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8603 (resp. --stack-auto), prepared for --xstack

8614 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8616 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8617 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8618 type for bits was changed. It resulted in bit variables becoming
8619 global, which is not permitted in PIC 14 assembly output.
8621 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8623 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8636 A few small changes that speed up the peephole optimizer.
8640 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8642 Try to make the peephole optimizer smarter by maintaining
8643 an association between the assembly source code and the
8644 iCodes that originated them. Put this information to use
8645 with a new peephole rule condition "notVolatile" so that
8646 the rules can be aggressive yet still safe.
8651 * src/mcs51/peeph.def
8653 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8657 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8658 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8659 if the left or right operand symbols have the accuse flag set.
8661 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8663 Changed the type of the result of the ! (NOT) operator to char;
8664 previously it returned the same type as the source. This allows
8665 us to eliminate all the genFloatNot functions (all of its target
8666 implementations were very buggy) since !float can use the same
8669 * src/SDCCicode.c (ast2iCode): ! returns char

8678 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8679 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8680 during interrupts. Ensure WSAVE is located at a shared bank address.
8681 2. Fixed page selection in some places
8682 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8683 the registers name strings.
8684 4. Fixed "signed / unsigned compare" compiler warnings.
8685 5. The PIC port manages its own allocation of the general purpose
8686 registers, but makes no attempt to reuse them. As a result when
8687 compiling it soon runs out of general purpose registers. Some
8688 additional code was added to the files pcode.c and device.c to walk
8689 through the function call tree and rename the registers so that they
8699 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8700 genPlus() & genMinus() when the result is the same as left or right

8706 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8708 Made bitfield a distinct type from bit so that bitfields
8709 convert as per ANSI C and bits retain their traditional
8710 boolean style behaviour. Implemented bitfield support in
8718 * src/ds390/gen.c: bit v bitfield split
8719 * src/z80/gen.c: New support for bitfields
8720 * support/regression/tests/bitfields.c: reenabled z80,
8723 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8725 Rules 246.x, 247.x relate to bitfields, the others speed up
8726 access to xdata mapped I/O devices.
8728 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8730 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8732 Cleaned up genPackBits and genUnpackBits and added two helper
8733 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8734 for literal assignments in genPackBits (thanks to Frieder for
8740 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8742 Fixed bug #748310 (pointer to function type mishandled when the
8743 function name is omitted). Also fixed a SIGSEGV when a function
8744 attribute (reentrant, etc) is used on a non-function or on a
8745 function but misplaced before the parameter list.
8747 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8749 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8750 * support/Util/SDCCerr.h,
8751 * support/Util/SDCCerr.c: Added func attr misuse error msg
8753 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8755 Fixed bug #787649 by anonymous
8756 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8772 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8774 Made the constant following the "interrupt" keyword optional. If
8775 omitted, the function will not automatically be given an entry
8776 in the interrupt vector table (similar to #pragma NOIV, but
8777 less syntacticly kludgy). The interrupt number is also now
8778 range checked. Also fixed a bug in the high order bit example

8792 * src/SDCCicode.c (operandOperation): rewritten some ops
8793 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8794 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8796 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8797 be re-activated by defining REDUCE_LITERALS)
8798 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8799 unsigned, but are signed by default
8800 * src/SDCCval.c (constVal): rearranged
8801 * src/SDCCval.c (valMod): preliminary fix
8802 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8844 constants are unsigned; added recognition of "u" flag for unsigned
8845 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8846 * src/SDCCval.c (valDiv, valMod): fixed signdness
8847 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8848 signedness of modulo, left and right shift

9307 * src/SDCCmain.c: linkOptions is changed to set *,
9308 added if/endif conditional macros to remove options help
9309 messages from optionsTable when a port is not configured, added
9310 support for the PIc16 port in the ports table, when executing
9311 the compiler with no port specified on command line, a default
9312 port is selected with the new macro DEFAULT_PORT which is
9313 defined in port.h, in setDefaultOptions() linkOptions is removed
9314 from initialization assignment, since now it is a set,
9315 parseCmdLine uses setParseWithComma for linkOptions, in
9316 linkEdit() linkOptions are accessed with new function indexSet()
9317 which returns the i'th item of a set variable. See SDCCset.c, in
9318 linkEdit() when calling buildCmdLine(), added linkOptions as
9319 last argument. Now users can pass arguments to gplink via the
9320 -Wl option, main() uses pic16glue() to glue up pic16 programs

9333 * src/pic16/main.c: __config directives are commented out to stop
9334 gpasm complaining and test the linkage with gplink, _linkCmd and
9335 _asmCmd changed to be more gplink and gpasm friendly
9336 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9337 produced an error when parsed, peep rule 12 is added to utilize
9338 movff, but it is commented out since the pCode does not support
9339 yet a command with 2 address arguments
9341 2003-05-18 <johan AT balder>
9343 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9370 2003-05-11 Borut Razem <borut.razem AT siol.net>
9372 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9373 the path of bin directory, so that PATH is the only env. variable, which has to be set
9374 in case of standard installation.

10382 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10384 2003-01-04 <johan AT balder>
10386 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10388 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10389 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10391 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10392 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10393 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10395 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10396 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10398 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10399 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10401 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10402 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10404 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10406 * in \sdcc\as\mcs51\ changed these files in order to create an
10407 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10408 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10409 following files to include the previous two files: aslink.dsp,
10410 Makefile.aslink, Makefile.bcc, and Makefile.in.
10412 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10413 .adb instead of .cdb
10415 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10417 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10418 value from option --iram-size.
10420 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10422 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10425 2002-09-18 <wiml AT hhhh.org>
10427 * SDCClrange.h: exposed setFromRange() and setToRange()
10428 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10429 packRegsForAccUse() (bug 542397)
10430 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10431 multiple times and emitting the fetch operations more than once
10432 added aopGetUsesAcc() function to allow binary operators to
10433 fetch their operands in the correct order; made genMinus() emit
10434 compact code for X = LITERAL - Y
10436 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10437 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10438 sprintf() in line 1267.
10440 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10441 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10444 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10445 Changes to aslink (All the changes are marked with 'JCF'):
10447 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10450 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10451 area BSEG. Also moves, if possible, the DATA area down into the internal
10452 ram so more space is available.
10454 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10457 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10458 not bytes. Function summary() which creates a memory usage summary
10459 file with extension .mem. Reports of overlaping stack and small stack
10460 size. If the space for the stack is less than 16 bytes aslink trows a
10463 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10464 the 8051. Option 'y' for memory summary output file.
10466 Changes to sdcc (All the changes are marked with 'JCF'):
10468 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10470 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10471 overlaying area for it (uses RegBankUsed[4]).
10473 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10474 bank zero as used by default. By default aslink locates the stack
10475 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10476 the creation of the .mem file. Delegates the allocation of data area
10477 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10478 the begining of the stack area to aslink.
10480 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10481 glue() in SDCCglue.c creates an area for it.
10483 2002-09-03 Borut Razem <borut.razem AT siol.net>
10484 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10485 sdcc/src/pic/glue.c:
10486 introduced atexit() handler for teporay files removal in case of
10487 errors, assertions, ...
10489 2002-08-29 Borut Razem <borut.razem AT siol.net>
10490 * sdcc/support/cpp2/auto-host_vc_in.h:
10491 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10492 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10493 Maybe there is a similar problem with BORLANDC? It should be checked!
10495 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10496 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10497 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10498 was not executed, and the compiler (cl) launched a warning:
10499 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10501 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10502 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10504 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10505 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10507 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10508 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10509 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10510 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10511 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10512 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10513 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10514 - added Release configuration in VS projects
10515 - review of compiler an linker options
10516 - VC .exe files are generated in bin_vc directory, not to interfere
10517 with binaries generated from other projects (cygwin, mingw, bcc ...)
10519 * sdcc/src/yacc.dsp: added
10521 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10522 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10523 and insert the version number definitions from .version
10525 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10527 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10528 added - genarate auto-host.h using auto-host_vc_in.h as template
10531 removed from CVS, generated automatically
10533 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10534 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10536 2002-08-11 Borut Razem <borut.razem AT siol.net>
10537 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10539 2002-08-10 Borut Razem <borut.razem AT siol.net>
10540 * src/SDCCmain.c (main):
10541 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10542 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10543 The consequence was that some temporary files were not removed.
10546 unification of code in functions tempfilename() and tempfile():
10547 function tempnam() is defined in Visual Studio 6.0 and .NET
10549 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
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 - removed compiler command line option /WX: Treats all warnings as errors
10554 - update a list of source files, included into the project
10556 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10557 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10558 changed project type to Generic Project so that can be correcly converted to VS.NET project
10560 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10562 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10564 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10566 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10567 added return 0 statements after assert() to make compiler happy
10569 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10570 added newline in the def file to keep MSC compiler satisfied
10572 * sdcc/src/z80/gen.c:
10573 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10574 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10575 - solved MSC error in function aopDump()
10577 * sdcc_vc.h: define PREFIX as "\\sdcc"
10579 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10580 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10583 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10584 - Rewrote the register banking algorithm.
10585 - Added pCode live-range analysis to registers (for now, only non-used and
10586 singly-used registers optimized away)
10588 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10590 * 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.

10617 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10619 2002-03-28 Johan Knol <johan AT balder>
10621 * src/SDCCval.c: fixed bug #532436
10623 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10628 Added -p option. Allows port dependent processor to be specified.
10631 Initialized the new field char *Processor field to NULL in all ports
10634 Compiler generated registers for interrupt context saving
10635 were not getting allocated.
10637 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10640 Fixed left shift. Will promote the left side of a left shift
10641 if a) left shifting more than size of operand or b) when assigned
10642 to something size > size of left side
10644 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10659 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10661 2002-03-04 johanknol <johanknol AT manik>
10663 * /src/SDCCval.c: fixed
10665 const unsigned char arr[][2] = { { 0, 1 } };

10752 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10754 * sdcc/src/SDCCloop.c:
10755 Previous fix was not good. basic blocks that have "break" or "return" are
10756 not really partof a loop , but live ranges used in these blocks should
10757 be live thru the entire loop, so set partOfLoop but don't add them to
10760 2002-02-21 <johan AT FRIJA>
10762 * src/SDCCcse.c: fixed bug #514308
10764 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10767 Fixed BUG #519583. If a conditional block ended in a return/break
10768 statement inside a loop, it was not being considered part of the loop.
10770 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10772 2002-02-10 Karl Bongers <karl AT turbobit.com>

10789 Karl and Johan start ucsim XA support. Most dissassembly working,
10790 about 75% emulation done(plenty of work remaining).
10792 * sim/ucsim/z80.src:
10793 Add Z80 support to ucsim, add test-ucz80 regression test,
10794 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10795 Notice z80 compiler fails on examples/test3.c/crc code.

10812 1) handle multiple send & receives from register bank1
10813 2) ralloc can now allocate DPTR1 to some liveRanges
10815 * src/SDCCsymt.c, src/SDCCsymt.h:
10816 changes to handle multiple sends & receives
10818 * src/SDCCptropt.h:
10819 added some pointer arithmetic optimization
