567 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
569 Enabled VPATH feature: changed nearly all Makefiles (149 files).
570 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
572 One basic decision: e.g. src/clean.mk includes further files. In order
573 to make this work there are two solutions:
574 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
575 run configure on them. This way they can use
576 'include $(srcdir)/port-clean.mk'
577 - always include clean.mk by the Makefile at the same level. To avoid
578 that `make clean` tries to include and build Makefile.dep the
579 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
580 implemented, because now even `make uninstall` doesn't create
581 Makefile.in. clean.mk could be eliminated by pasting it in
584 * debugger/mcs51/Makefile.in: build own objects from library sources
585 (SLIB, SDCC) in current directory
587 * configure, configure.in: renamed --disable-device-lib-build in
588 --disable-device-lib; added --enable-doc, the required tools are
589 searched by configure; added result message; the toolchain for the
590 belonging ports are now only built, if the port is enabled.
592 * support/regression/*: all output is written in directory gen, because
593 the fwk and ports directories don't livet in the build tree using vpath
595 * doc/sdccman.lyx: renamed --disable-device-lib-build to
596 --disable-device-lib, added --enable-doc, added section VPATH
598 * sim/ucsim/configure.in,
599 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
600 z80 are enabled by default
602 2006-04-24 Raphael Neider <rneider AT web.de>
604 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
605 to config word, "pic14_"-prefixed some extern functions
606 (pic14_emitConfigWord): emit __config directive(s) if assignment to
607 config word has been found
608 * src/pic/device.h: added prototypes
609 * src/pic/pcode.c: added "pic14_"-prefix where needed

626 fixes #1469504 and #1474602,
627 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

945 (aopForSym, aopOp): increment asmop.allocated if reused,
946 (freeAsmop): decrement asmop.allocated and check for zero instead of
948 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
949 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
950 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

971 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
973 2006-03-06 Borut Razem <borut.razem AT siol.net>
975 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
976 made the linker quiet
978 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
980 * src/pic16/gen.c (genPcall): fixed bug #1443644
981 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
982 which dumps before the function entry point a data byte which represents
983 the number of the local variables used by the specified function, added
984 'xinst' for initial support for Extended Instruction Support,
985 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
986 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
987 port->fun_prefix anymore (may change later),

991 (genOr): removed some legacy pic-port instructions,
992 * src/pic16/genarith.c (genAddLit): re-enabled old code because
993 performing operations with SFR's causes data to be written more than
994 once to each SFR. Perhaps SFRs should be handled in special cases...
995 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
997 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1000 --extended or -y for Extended Instruction Support,
1001 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1002 (deassignLRs): *** perhaps the most important change, old 'for' code
1003 (commented out for reference), didn't account for some registers which
1004 were left marked 'not free' after a pointer operation. The change
1005 reduces register usage a lot in some cases

3280 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3281 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3282 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3283 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3284 always available in leading double underscore form. The C99 support is
3285 mostly missing, but it's a start.
3286 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3287 reserved identifier "__data".
3289 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3365 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3367 * device/lib/printf_large.c: removed inline assembly for portability and
3368 readability. Use printf_fast if speed or size are more important.
3369 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3370 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3372 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3374 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3375 prevent compiler warning
3377 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3379 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3380 moved to level 0 and declared as static. Also they are explicit
3381 placed in access bank. This was necessery because some times they
3382 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3383 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3384 optimizations. Currently only compare to unsigned char is implemented,
3385 * src/pic16/gen.c: added fReturnIdx array,
3386 * (struct resolvedIfx) is moved to gen.h and made public,
3387 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3388 * (aopForSym): added an optimization to directly store in stack of
3389 the operand of a SEND iCode,
3390 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3391 but as registers instead (AOP_REG) using the fReturnIdx array,
3392 * (pic16_freeAsmop): remove the freed register from the
3393 _G.sregsAlloc field,
3394 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3395 a compare of 'WREG',
3396 * (pic16_popGetTempRegCond): changed function prototype, now
3397 function takes also a bitVector argument v which holds the current
3398 set of registers that are allocated for stack access by aopForSym,
3399 registers allocated in aopForSym for accessing stack symbols are not
3400 any more part of the functions usedRegs field,
3401 * (genCall): some times aopOp is called for a stack variable to be
3402 send, aopForSym might perform the push, if this is true make sure
3403 that genCall doesn't push the variable twice by testing _G.resDirect,
3404 * (genFunction): changed testing for unspecified interrupt number
3405 from 256 to INTNO_UNSPEC,
3406 * modified selection scheme of frame pointer generation. Previously
3407 if function did use local registers a frame pointer was generated,
3408 now a frame pointer is generated only if function has arguments
3409 (that need PLUSW2 register access), or has stack arguments, or the
3410 compiler is not instructed to omit the frame pointer,
3411 * (genEndFunction): before restoring local registers that were saved
3412 in the function preamble, also restore the registers that *might*
3413 have been allocated for stack access,
3414 * (genRet): removed some old comments,
3415 * (genCmp, the active (RN's) version): added a call to the
3416 pic16_genCmp_special function to perform the compare with a more
3417 robust and optimized way,
3418 * (genInline): a feature has been added in inline code generation,
3419 which allows a wildcard variable substitution when writing inline
3420 assembly. Code is incomplete and experimental therefore undocumented,
3421 * (genCast): changed order of aopOp for result and right to allow
3422 aopForSym to directly load the result if possible,
3423 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3424 perform an optimized compare on some selected special occasions,
3425 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3426 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3427 generate an IVT any more,
3428 * src/pic16/main.c (pic16_optionsTable): added command line option
3430 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3431 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3433 * src/pic16/NOTES: Raphael Neider added in list of active developers
3434 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3435 jumptable_end to prevent bug #,
3436 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3437 inCond and outCond fields,
3438 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3439 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3440 turn off register spilling,
3441 * (packRegsForOneUse): synced with other ports' versions although it
3442 is not used currently,
3443 * (pic16_packRegisters): added an optimization while reading
3444 structure bitfields, some registers may be saved (malloc code is
3445 decreased by 80 bytes)
3447 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3449 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3450 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3451 this can be optimized more?
3453 2005-03-10 Raphael Neider <rneider AT web.de>
3455 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3456 genNearPointerGet): (hopefully) fixed access to bitfields via
3457 pointers (p->bitN = x; and x = p->bitN; failed)
3459 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3461 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3463 2005-03-09 Raphael Neider <rneider AT web.de>

3467 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3469 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
3470 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
3471 (regTypeNum): set REG_BIT type if necessary
3472 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

4091 Adding support for replacing ljmps with sjmps in jumptables
4092 generated for switch statements. For now you need to set the
4093 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4094 Now 4 algorithms for mcs51 jumptable generation are used:
4095 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4096 addresses loaded pc-relative for up to 112 cases and stack-pushing
4097 target addresses loaded with offset from dptr for up to 256 cases.

4127 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4129 * added libc directory. The current version of LibC contains string
4130 functions, ctype functions and macros and some functions of the
4131 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4132 be extensively tested in the future. Standard disclaimer here.
4133 Library is not automatically build yet. But one can build it by
4134 invoking 'make' inside the libc directory.

4144 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4145 * (pic16_storeForReturn): optimized return of 0,
4146 * (genCmp): experimental code for new genCmp which uses PIC18's
4147 special compare&skip instructions. Initial tests fail some times
4148 with variables grater than 1 byte in size, so new code is disabled,
4149 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4151 * (genCast): began a fix to optimize the casting of a bit to another
4152 bit, now assigning a bitfield to another bitfield will fail, sorry,
4153 * src/pic16/main.c: disabled the use of lr-support feature,
4154 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4157 bits with offset (case PO_GPR_BIT),
4158 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4160 * (isBankInstruction): modified to return 0 for no banking instruction,
4161 and 1 for banking instruction,
4162 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4163 caused stop processing pCodes after a inline assembly block,
4164 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4165 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4166 registers when it shouldn't,
4167 * src/pic16/ralloc.c (allocReg): add preliminary support for
4168 supporting a limited set of temporary registers,
4170 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4172 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4173 genDataPointerSet): ensure assignments always copy in MSB to LSB
4175 (loadRegFromAop): recognize CLRH optimization,
4176 (genFunction): optimize RECEIVE iCodes in reentrant functions
4178 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4180 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7178 loaded with the linker search paths (-L arguments) and the libraries
7179 to be linked with the current source (-l arguments). Changes
7180 currently will affect only the pic16 port.
7181 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7182 include path the port specific paths and port specific libraries,
7183 * gplink command now contains the $3 argument,
7184 * src/pic16/device.h,
7185 * src/pic16/device.c,: structure PIC_device is made public and
7186 renamed to PIC16_device, the same for variable Pics which is renamed

7201 Documenting changes from previous commits.
7202 * configure.in (version 1.56),
7203 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7204 when generating output files to configure the pic16 library,
7205 but now I've commented it out, since gputils aren't installed in the
7206 SF compile farm, so library won't compile
7208 * device/lib/Makefile.in (version 1.56): initially I've added in
7209 target 'all' the prerequestive 'model-pic16' so it compiled the
7210 pic16 library, but now I've commented it out for the same reasons
7212 * added targets 'model-pic16' and 'objects-pic16' to compile the
7214 * added target 'port-specific-objects-pic16' to handle the
7215 generated libraries and copy them into the build/ directory
7216 * added target 'clean-intermediate-pic16' to clean intermediate
7217 files into pic16 directory
7218 * in target 'installdirs' added line to create directory pic16 in

7484 * src/SDCCsymt.c (newEnumType),
7486 * support/Util/SDCCerr.c,
7487 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7489 * support/regression/tests/enum.c: added test for enum values that
7490 require at least 2 bytes of storage.
7492 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7494 * src/common.h: added ifndef/define/endif macros
7495 around the header file.
7496 Bug reported from Jesus Calvino-Fraga
7498 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7500 * sdcc.spec: updated
7501 * device/include/Makefile.in: don't install CVS directories
7502 * device/lib/Makefile.in: added removal of CVS directories after install
7503 * doc/Makefile: fixed install, added local_icons
7504 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7505 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7506 * src/ds390/gen.c (genRightShift): fixed bug #870788
7507 * src/SDCCast.c (decorateType): fixed bug #870781
7509 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7511 PIC16 port related changes:
7512 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7513 added variable stackPos,
7515 * gen.c: genCall, assignResultValue: added support for
7516 pushing/retrieving function parameters to/from stack,
7517 genFunction,genEndFunction: setup stack frame for the
7519 genAddrOf: will be changed according to bug 863624
7521 * added files genutils.c and genutils.h which contain gen*
7522 debugged and optimised functions extracted from gen.c
7524 * glue.c: added variable 'externs' which holds extern symbols,
7525 pic16emitRegularMap: is modified to properly handle relocatable
7526 symbols under the new scheme,
7527 pic16createInterruptVect: is modified
7528 pic16printPublics: is modified to emit 'global' assembler directives,
7529 added pic16_printExterns to print extern symbols,
7530 pic16glue: initializes stack/frame pointer in the beginning of
7531 the assembly output. Temporary hack, will be corrected later,
7532 because gplink yet does not support stack and SDCC does not
7533 yet support a type of crt0.o object to create the final binary.
7535 * Removed many lines that contain 8051 legacy code.
7536 * The code is finally placed under a 'code' directive.
7537 * Added port specific options.
7539 * _process_pragma: simplified since now we do not need *special*
7540 include file to define SFR registers. But a separate header
7541 will be needed. This will be developed later.
7542 * _pic16_parseOptions: added, parses port specific options:
7543 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7544 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7545 --preplace-udata-with=
7547 * _pic16_setDefaultOptions: modified to initialize section names,
7548 but hack is temporarly out of order since it needs improvement.
7549 * _pic16_genAssemblerPreamble: configuration words are emitted by
7550 their address instead of their name. This part is incomplete and
7551 supports only the 18Fxx2 devices. Other devices will emit an error
7552 during assembly since they do not contain the same set of config
7554 * _pic16_genIVT: is modified,
7556 * pcode.c: added definitions for some hardware registers that are needed
7558 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7559 All PCI entries are updated. Now LFSR is supported.
7560 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7561 * added pic16_newpCodeOpLit2 to support instructions with
7562 two literal arguments
7563 * pic16_pCode2str: corrected code that emits assembler instructions
7564 with two literal operands and those that have an access bit modifier
7565 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7566 this fixes a bug which caused some labels to be lost, when an
7567 assembler directive was added, i.e. banksel,
7568 * pic16_FixRegisterBanking: improved logic that causes the insertion
7570 * InlineFunction: functions that are called once, are not any more
7571 inlined. This can be a port option in the future,
7573 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7575 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7576 hold the corresponding uninitialized symbols,
7577 * pic16_allocProcessorRegister: registers have explicit marked the
7579 * pic16_allocInternalRegister: registers are explicit marked as
7581 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7582 processing list, so bit registers were lost,
7585 * ralloc.h: added field 'accessBank' and original symbol operand
7586 in register definition,
7587 * removed the field isMapped from register definition,
7589 ** Several functions have been removed from various sources:
7590 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7591 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7592 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7593 pic16_assignRelocatableRegisters
7595 ** others have been introduced:
7596 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7597 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7599 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7601 * support/scripts/inc2h.pl: changed definition of BIT_AT
7602 to emit 'sbit at' instead of 'bit at'. This was a request.
7604 PIC16 port related preliminary changes:
7605 * gen.c: prefixed function popRegFromString with
7606 pic16_ and all references to it corrected
7607 * pcode.c: all pic16_pc_* hardware registers prefixed
7608 with underscore (_),
7609 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7610 * ralloc.c: newReg(): when register is REG_SFR then
7611 set address to rIdx,
7612 pic16_allocProcessorRegister(): marks register wasUsed=0
7613 pic16_writeUsedRegs(): added a call to assign processor
7614 registers via pic16_assignFixedRegisters
7616 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7618 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7619 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7620 variables in unused register banks. Also the SSEG is placed
7621 wherever there is enough space for it, and IDATA can be anywhere
7622 in internal RAM. For now compile using -Wl-Y[stack_size].
7623 The mem file is different for this option as well, since it
7624 makes no sense of talking about DSEG lenght.
7626 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7628 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7629 in certain cases, e.g. when ROM assignment, patch provided
7630 from Albert den Haan.
7632 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7871 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7873 * src/SDCCast.c (decorateType): disabled a transformation I added in
7874 revision 1.188 (access to fields of a structure at an absolute address);
7875 it breaks with bitfields, extern declarations, and gcse analysis.
7876 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7877 could be assigned through a pointer, so don't complain.
7878 * src/SDCCast.c (astErrors),
7880 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8518 support for standard C idiom of memory mapped variables; for
8519 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8520 to xdata int at 0x1234 tempvar = 1.
8521 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8522 provided by Akiya ISHIDA

8538 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8540 Fixed bug #621531 (const & volatile confusion in the type chain).
8541 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8634 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8635 fetching of the pointer
8636 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8637 copied from genNearPointerSet()
8638 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8639 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8653 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8655 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8656 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8657 type for bits was changed. It resulted in bit variables becoming
8658 global, which is not permitted in PIC 14 assembly output.
8660 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8662 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8675 A few small changes that speed up the peephole optimizer.
8679 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8681 Try to make the peephole optimizer smarter by maintaining
8682 an association between the assembly source code and the
8683 iCodes that originated them. Put this information to use
8684 with a new peephole rule condition "notVolatile" so that
8685 the rules can be aggressive yet still safe.
8690 * src/mcs51/peeph.def
8692 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8696 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8697 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8698 if the left or right operand symbols have the accuse flag set.
8700 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8702 Changed the type of the result of the ! (NOT) operator to char;
8703 previously it returned the same type as the source. This allows
8704 us to eliminate all the genFloatNot functions (all of its target
8705 implementations were very buggy) since !float can use the same
8708 * src/SDCCicode.c (ast2iCode): ! returns char

8717 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8718 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8719 during interrupts. Ensure WSAVE is located at a shared bank address.
8720 2. Fixed page selection in some places
8721 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8722 the registers name strings.
8723 4. Fixed "signed / unsigned compare" compiler warnings.
8724 5. The PIC port manages its own allocation of the general purpose
8725 registers, but makes no attempt to reuse them. As a result when
8726 compiling it soon runs out of general purpose registers. Some
8727 additional code was added to the files pcode.c and device.c to walk
8728 through the function call tree and rename the registers so that they
8738 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8739 genPlus() & genMinus() when the result is the same as left or right

8745 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8747 Made bitfield a distinct type from bit so that bitfields
8748 convert as per ANSI C and bits retain their traditional
8749 boolean style behaviour. Implemented bitfield support in
8757 * src/ds390/gen.c: bit v bitfield split
8758 * src/z80/gen.c: New support for bitfields
8759 * support/regression/tests/bitfields.c: reenabled z80,
8762 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8764 Rules 246.x, 247.x relate to bitfields, the others speed up
8765 access to xdata mapped I/O devices.
8767 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8769 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8771 Cleaned up genPackBits and genUnpackBits and added two helper
8772 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8773 for literal assignments in genPackBits (thanks to Frieder for
8779 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8781 Fixed bug #748310 (pointer to function type mishandled when the
8782 function name is omitted). Also fixed a SIGSEGV when a function
8783 attribute (reentrant, etc) is used on a non-function or on a
8784 function but misplaced before the parameter list.
8786 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8788 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8789 * support/Util/SDCCerr.h,
8790 * support/Util/SDCCerr.c: Added func attr misuse error msg

8811 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8813 Made the constant following the "interrupt" keyword optional. If
8814 omitted, the function will not automatically be given an entry
8815 in the interrupt vector table (similar to #pragma NOIV, but
8816 less syntacticly kludgy). The interrupt number is also now
8817 range checked. Also fixed a bug in the high order bit example

8831 * src/SDCCicode.c (operandOperation): rewritten some ops
8832 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8833 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8835 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8836 be re-activated by defining REDUCE_LITERALS)
8837 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8838 unsigned, but are signed by default
8839 * src/SDCCval.c (constVal): rearranged
8840 * src/SDCCval.c (valMod): preliminary fix
8841 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9346 * src/SDCCmain.c: linkOptions is changed to set *,
9347 added if/endif conditional macros to remove options help
9348 messages from optionsTable when a port is not configured, added
9349 support for the PIc16 port in the ports table, when executing
9350 the compiler with no port specified on command line, a default
9351 port is selected with the new macro DEFAULT_PORT which is
9352 defined in port.h, in setDefaultOptions() linkOptions is removed
9353 from initialization assignment, since now it is a set,
9354 parseCmdLine uses setParseWithComma for linkOptions, in
9355 linkEdit() linkOptions are accessed with new function indexSet()
9356 which returns the i'th item of a set variable. See SDCCset.c, in
9357 linkEdit() when calling buildCmdLine(), added linkOptions as
9358 last argument. Now users can pass arguments to gplink via the
9359 -Wl option, main() uses pic16glue() to glue up pic16 programs

9373 gpasm complaining and test the linkage with gplink, _linkCmd and
9374 _asmCmd changed to be more gplink and gpasm friendly
9375 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9376 produced an error when parsed, peep rule 12 is added to utilize
9377 movff, but it is commented out since the pCode does not support
9378 yet a command with 2 address arguments
9380 2003-05-18 <johan AT balder>
9382 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9409 2003-05-11 Borut Razem <borut.razem AT siol.net>
9411 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10400 2003-01-07 <johan AT balder>
10402 * src/SDCCast.c (decorateType): fixed bug #600035
10404 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10405 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10406 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10407 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10408 * src/pic/pcode.c: outcommented unused variable to remove warnings
10409 * src/pic/ralloc.c: outcommented unused variable to remove warnings
10411 2003-01-06 <karl AT turbobit.com>

10415 2003-01-06 <johan AT balder>
10417 * src/SDCCicode.c: fixed array add
10419 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10420 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10421 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10423 2003-01-04 <johan AT balder>
10425 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10427 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10428 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10430 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10431 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10432 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10434 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10435 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10437 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10438 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10440 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10441 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10443 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10445 * in \sdcc\as\mcs51\ changed these files in order to create an
10446 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10447 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10448 following files to include the previous two files: aslink.dsp,
10449 Makefile.aslink, Makefile.bcc, and Makefile.in.
10451 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10452 .adb instead of .cdb
10454 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10456 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10457 value from option --iram-size.
10459 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10461 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10464 2002-09-18 <wiml AT hhhh.org>
10466 * SDCClrange.h: exposed setFromRange() and setToRange()
10467 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10468 packRegsForAccUse() (bug 542397)
10469 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10470 multiple times and emitting the fetch operations more than once
10471 added aopGetUsesAcc() function to allow binary operators to
10472 fetch their operands in the correct order; made genMinus() emit
10473 compact code for X = LITERAL - Y
10475 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10476 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10477 sprintf() in line 1267.
10479 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10480 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10483 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10484 Changes to aslink (All the changes are marked with 'JCF'):
10486 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10489 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10490 area BSEG. Also moves, if possible, the DATA area down into the internal
10491 ram so more space is available.
10493 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10496 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10497 not bytes. Function summary() which creates a memory usage summary
10498 file with extension .mem. Reports of overlaping stack and small stack
10499 size. If the space for the stack is less than 16 bytes aslink trows a
10502 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10503 the 8051. Option 'y' for memory summary output file.
10505 Changes to sdcc (All the changes are marked with 'JCF'):
10507 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10509 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10510 overlaying area for it (uses RegBankUsed[4]).
10512 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10513 bank zero as used by default. By default aslink locates the stack
10514 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10515 the creation of the .mem file. Delegates the allocation of data area
10516 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10517 the begining of the stack area to aslink.
10519 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10520 glue() in SDCCglue.c creates an area for it.
10522 2002-09-03 Borut Razem <borut.razem AT siol.net>
10523 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10524 sdcc/src/pic/glue.c:
10525 introduced atexit() handler for teporay files removal in case of
10526 errors, assertions, ...
10528 2002-08-29 Borut Razem <borut.razem AT siol.net>
10529 * sdcc/support/cpp2/auto-host_vc_in.h:
10530 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10531 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10532 Maybe there is a similar problem with BORLANDC? It should be checked!
10534 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10535 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10536 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10537 was not executed, and the compiler (cl) launched a warning:
10538 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10540 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10541 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10543 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10544 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10546 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10547 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10548 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10549 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10550 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10551 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10552 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10553 - added Release configuration in VS projects
10554 - review of compiler an linker options
10555 - VC .exe files are generated in bin_vc directory, not to interfere
10556 with binaries generated from other projects (cygwin, mingw, bcc ...)
10558 * sdcc/src/yacc.dsp: added
10560 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10561 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10562 and insert the version number definitions from .version
10564 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10566 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10567 added - genarate auto-host.h using auto-host_vc_in.h as template
10570 removed from CVS, generated automatically
10572 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10573 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10575 2002-08-11 Borut Razem <borut.razem AT siol.net>
10576 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10578 2002-08-10 Borut Razem <borut.razem AT siol.net>
10579 * src/SDCCmain.c (main):
10580 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10581 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10582 The consequence was that some temporary files were not removed.
10585 unification of code in functions tempfilename() and tempfile():
10586 function tempnam() is defined in Visual Studio 6.0 and .NET
10588 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10590 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10591 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10592 - removed compiler command line option /WX: Treats all warnings as errors
10593 - update a list of source files, included into the project
10595 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10596 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10597 changed project type to Generic Project so that can be correcly converted to VS.NET project
10599 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10601 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10603 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10605 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10606 added return 0 statements after assert() to make compiler happy
10608 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10609 added newline in the def file to keep MSC compiler satisfied
10611 * sdcc/src/z80/gen.c:
10612 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10613 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10614 - solved MSC error in function aopDump()
10616 * sdcc_vc.h: define PREFIX as "\\sdcc"
10618 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10619 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10622 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10623 - Rewrote the register banking algorithm.
10624 - Added pCode live-range analysis to registers (for now, only non-used and
10625 singly-used registers optimized away)
10627 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10629 * 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.

10652 * src/z80/main.c: Added force callee saves for jaune.
10654 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10656 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10658 2002-03-28 Johan Knol <johan AT balder>
10660 * src/SDCCval.c: fixed bug #532436
10662 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10664 Added "char *Processor" field to the port structure.
10667 Added -p option. Allows port dependent processor to be specified.
10670 Initialized the new field char *Processor field to NULL in all ports
10673 Compiler generated registers for interrupt context saving
10674 were not getting allocated.
10676 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10679 Fixed left shift. Will promote the left side of a left shift
10680 if a) left shifting more than size of operand or b) when assigned
10681 to something size > size of left side
10683 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10685 tons of changes. Register allocation has been
10686 rewritten. Added customization for the various PICs. Flow
10687 analysis is restructured. ...
10689 * src/pic/device.h:
10692 * src/pic/device.c:
10693 Added. device.c is a PIC port hack to accomodate variations
10696 2002-03-13 Michael Hope <michaelh AT vroom>
10698 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10700 2002-03-04 johanknol <johanknol AT manik>
10702 * /src/SDCCval.c: fixed
10704 const unsigned char arr[][2] = { { 0, 1 } };
10705 t18.c:1: error: Initializer element is not constant

10791 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10793 * sdcc/src/SDCCloop.c:
10794 Previous fix was not good. basic blocks that have "break" or "return" are
10795 not really partof a loop , but live ranges used in these blocks should
10796 be live thru the entire loop, so set partOfLoop but don't add them to
10799 2002-02-21 <johan AT FRIJA>
10801 * src/SDCCcse.c: fixed bug #514308
10803 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10806 Fixed BUG #519583. If a conditional block ended in a return/break
10807 statement inside a loop, it was not being considered part of the loop.
10809 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10811 2002-02-10 Karl Bongers <karl AT turbobit.com>

10815 with lots of comments and notes.
10817 * device/examples/test2.c:
10818 Fix bug, "red" variable not being initialized(compiler complained).
10820 * device/examples/Makefile, examples/test3.c:
10821 Add Makefile in device/examples folder, compiles test3.c
10822 for use as a multiple module SDCDB test case.
10824 * sim/ucsim/cmd.src/cmdset.cc:
10825 Took out debug printfs in ucsim "next" command.
10827 * sim/ucsim/xa.src:
10828 Karl and Johan start ucsim XA support. Most dissassembly working,
10829 about 75% emulation done(plenty of work remaining).
10831 * sim/ucsim/z80.src:
10832 Add Z80 support to ucsim, add test-ucz80 regression test,
10833 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10834 Notice z80 compiler fails on examples/test3.c/crc code.
10836 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10838 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10846 from a memory mapped port
10847 2) added __builtin_memcmp
10848 3) added __builtin_swapw swap bytes of a short
10850 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10851 1) handle multiple send & receives from register bank1
10852 2) ralloc can now allocate DPTR1 to some liveRanges
10854 * src/SDCCsymt.c, src/SDCCsymt.h:
10855 changes to handle multiple sends & receives
10857 * src/SDCCptropt.h:
10858 added some pointer arithmetic optimization
10860 * src/SDCCptropt.c:
10861 added some pointer arithmetic optimizations but not stable yet so not
