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

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

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

972 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
974 2006-03-06 Borut Razem <borut.razem AT siol.net>
976 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
977 made the linker quiet
979 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
981 * src/pic16/gen.c (genPcall): fixed bug #1443644
982 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
983 which dumps before the function entry point a data byte which represents
984 the number of the local variables used by the specified function, added
985 'xinst' for initial support for Extended Instruction Support,
986 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
987 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
988 port->fun_prefix anymore (may change later),
989 (genFunction, genEndFunction): do not store/restore local registers for
990 _main (this should take care the --main-return command line option in
992 (genOr): removed some legacy pic-port instructions,
993 * src/pic16/genarith.c (genAddLit): re-enabled old code because
994 performing operations with SFR's causes data to be written more than
995 once to each SFR. Perhaps SFRs should be handled in special cases...
996 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
998 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1001 --extended or -y for Extended Instruction Support,
1002 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1003 (deassignLRs): *** perhaps the most important change, old 'for' code
1004 (commented out for reference), didn't account for some registers which
1005 were left marked 'not free' after a pointer operation. The change
1006 reduces register usage a lot in some cases

3281 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3282 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3283 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3284 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3285 always available in leading double underscore form. The C99 support is

3366 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3368 * device/lib/printf_large.c: removed inline assembly for portability and
3369 readability. Use printf_fast if speed or size are more important.
3370 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3371 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3373 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3375 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3376 prevent compiler warning
3378 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3380 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3381 moved to level 0 and declared as static. Also they are explicit
3382 placed in access bank. This was necessery because some times they
3383 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3384 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3385 optimizations. Currently only compare to unsigned char is implemented,
3386 * src/pic16/gen.c: added fReturnIdx array,
3387 * (struct resolvedIfx) is moved to gen.h and made public,
3388 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3389 * (aopForSym): added an optimization to directly store in stack of
3390 the operand of a SEND iCode,
3391 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3392 but as registers instead (AOP_REG) using the fReturnIdx array,
3393 * (pic16_freeAsmop): remove the freed register from the
3394 _G.sregsAlloc field,
3395 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3396 a compare of 'WREG',
3397 * (pic16_popGetTempRegCond): changed function prototype, now
3398 function takes also a bitVector argument v which holds the current
3399 set of registers that are allocated for stack access by aopForSym,
3400 registers allocated in aopForSym for accessing stack symbols are not
3401 any more part of the functions usedRegs field,
3402 * (genCall): some times aopOp is called for a stack variable to be
3403 send, aopForSym might perform the push, if this is true make sure
3404 that genCall doesn't push the variable twice by testing _G.resDirect,
3405 * (genFunction): changed testing for unspecified interrupt number
3406 from 256 to INTNO_UNSPEC,
3407 * modified selection scheme of frame pointer generation. Previously
3408 if function did use local registers a frame pointer was generated,
3409 now a frame pointer is generated only if function has arguments
3410 (that need PLUSW2 register access), or has stack arguments, or the
3411 compiler is not instructed to omit the frame pointer,
3412 * (genEndFunction): before restoring local registers that were saved
3413 in the function preamble, also restore the registers that *might*
3414 have been allocated for stack access,
3415 * (genRet): removed some old comments,
3416 * (genCmp, the active (RN's) version): added a call to the
3417 pic16_genCmp_special function to perform the compare with a more
3418 robust and optimized way,
3419 * (genInline): a feature has been added in inline code generation,
3420 which allows a wildcard variable substitution when writing inline
3421 assembly. Code is incomplete and experimental therefore undocumented,
3422 * (genCast): changed order of aopOp for result and right to allow
3423 aopForSym to directly load the result if possible,
3424 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3425 perform an optimized compare on some selected special occasions,
3426 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3427 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3428 generate an IVT any more,
3429 * src/pic16/main.c (pic16_optionsTable): added command line option
3431 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3432 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3434 * src/pic16/NOTES: Raphael Neider added in list of active developers
3435 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3436 jumptable_end to prevent bug #,
3437 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3438 inCond and outCond fields,
3439 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3440 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3441 turn off register spilling,
3442 * (packRegsForOneUse): synced with other ports' versions although it
3443 is not used currently,
3444 * (pic16_packRegisters): added an optimization while reading
3445 structure bitfields, some registers may be saved (malloc code is
3446 decreased by 80 bytes)
3448 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3450 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3451 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3452 this can be optimized more?
3454 2005-03-10 Raphael Neider <rneider AT web.de>
3456 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3457 genNearPointerGet): (hopefully) fixed access to bitfields via
3458 pointers (p->bitN = x; and x = p->bitN; failed)
3460 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3462 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
3464 2005-03-09 Raphael Neider <rneider AT web.de>
3466 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
3468 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
3470 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
3471 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
3472 (regTypeNum): set REG_BIT type if necessary
3473 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

4092 Adding support for replacing ljmps with sjmps in jumptables
4093 generated for switch statements. For now you need to set the
4094 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4095 Now 4 algorithms for mcs51 jumptable generation are used:
4096 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4097 addresses loaded pc-relative for up to 112 cases and stack-pushing
4098 target addresses loaded with offset from dptr for up to 256 cases.

4128 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4130 * added libc directory. The current version of LibC contains string
4131 functions, ctype functions and macros and some functions of the
4132 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4133 be extensively tested in the future. Standard disclaimer here.
4134 Library is not automatically build yet. But one can build it by
4135 invoking 'make' inside the libc directory.

4146 * (pic16_storeForReturn): optimized return of 0,
4147 * (genCmp): experimental code for new genCmp which uses PIC18's
4148 special compare&skip instructions. Initial tests fail some times
4149 with variables grater than 1 byte in size, so new code is disabled,
4150 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4152 * (genCast): began a fix to optimize the casting of a bit to another
4153 bit, now assigning a bitfield to another bitfield will fail, sorry,
4154 * src/pic16/main.c: disabled the use of lr-support feature,
4155 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4161 * (isBankInstruction): modified to return 0 for no banking instruction,
4162 and 1 for banking instruction,
4163 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4164 caused stop processing pCodes after a inline assembly block,
4165 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4166 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4167 registers when it shouldn't,
4168 * src/pic16/ralloc.c (allocReg): add preliminary support for
4169 supporting a limited set of temporary registers,
4171 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4173 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4174 genDataPointerSet): ensure assignments always copy in MSB to LSB
4176 (loadRegFromAop): recognize CLRH optimization,
4177 (genFunction): optimize RECEIVE iCodes in reentrant functions
4179 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4181 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

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

7202 Documenting changes from previous commits.
7203 * configure.in (version 1.56),
7204 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7205 when generating output files to configure the pic16 library,
7206 but now I've commented it out, since gputils aren't installed in the
7207 SF compile farm, so library won't compile
7209 * device/lib/Makefile.in (version 1.56): initially I've added in
7210 target 'all' the prerequestive 'model-pic16' so it compiled the
7211 pic16 library, but now I've commented it out for the same reasons
7213 * added targets 'model-pic16' and 'objects-pic16' to compile the
7215 * added target 'port-specific-objects-pic16' to handle the
7216 generated libraries and copy them into the build/ directory
7217 * added target 'clean-intermediate-pic16' to clean intermediate
7218 files into pic16 directory
7219 * in target 'installdirs' added line to create directory pic16 in

7223 added lines to copy all header files to installation path,
7224 * in target 'installdirs' added line create directory for pic16
7225 headers in the installation path

7485 * src/SDCCsymt.c (newEnumType),
7487 * support/Util/SDCCerr.c,
7488 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7490 * support/regression/tests/enum.c: added test for enum values that
7491 require at least 2 bytes of storage.
7493 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7495 * src/common.h: added ifndef/define/endif macros
7496 around the header file.
7497 Bug reported from Jesus Calvino-Fraga
7499 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7501 * sdcc.spec: updated
7502 * device/include/Makefile.in: don't install CVS directories
7503 * device/lib/Makefile.in: added removal of CVS directories after install
7504 * doc/Makefile: fixed install, added local_icons
7505 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7506 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7507 * src/ds390/gen.c (genRightShift): fixed bug #870788
7508 * src/SDCCast.c (decorateType): fixed bug #870781
7510 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7512 PIC16 port related changes:
7513 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7514 added variable stackPos,
7516 * gen.c: genCall, assignResultValue: added support for
7517 pushing/retrieving function parameters to/from stack,
7518 genFunction,genEndFunction: setup stack frame for the
7520 genAddrOf: will be changed according to bug 863624
7522 * added files genutils.c and genutils.h which contain gen*
7523 debugged and optimised functions extracted from gen.c
7525 * glue.c: added variable 'externs' which holds extern symbols,
7526 pic16emitRegularMap: is modified to properly handle relocatable
7527 symbols under the new scheme,
7528 pic16createInterruptVect: is modified
7529 pic16printPublics: is modified to emit 'global' assembler directives,
7530 added pic16_printExterns to print extern symbols,
7531 pic16glue: initializes stack/frame pointer in the beginning of
7532 the assembly output. Temporary hack, will be corrected later,
7533 because gplink yet does not support stack and SDCC does not
7534 yet support a type of crt0.o object to create the final binary.
7536 * Removed many lines that contain 8051 legacy code.
7537 * The code is finally placed under a 'code' directive.
7538 * Added port specific options.
7540 * _process_pragma: simplified since now we do not need *special*
7541 include file to define SFR registers. But a separate header
7542 will be needed. This will be developed later.
7543 * _pic16_parseOptions: added, parses port specific options:
7544 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7545 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7546 --preplace-udata-with=
7548 * _pic16_setDefaultOptions: modified to initialize section names,
7549 but hack is temporarly out of order since it needs improvement.
7550 * _pic16_genAssemblerPreamble: configuration words are emitted by
7551 their address instead of their name. This part is incomplete and
7552 supports only the 18Fxx2 devices. Other devices will emit an error
7553 during assembly since they do not contain the same set of config
7555 * _pic16_genIVT: is modified,
7557 * pcode.c: added definitions for some hardware registers that are needed
7559 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7560 All PCI entries are updated. Now LFSR is supported.
7561 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7562 * added pic16_newpCodeOpLit2 to support instructions with
7563 two literal arguments
7564 * pic16_pCode2str: corrected code that emits assembler instructions
7565 with two literal operands and those that have an access bit modifier
7566 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7567 this fixes a bug which caused some labels to be lost, when an
7568 assembler directive was added, i.e. banksel,
7569 * pic16_FixRegisterBanking: improved logic that causes the insertion
7571 * InlineFunction: functions that are called once, are not any more
7572 inlined. This can be a port option in the future,
7574 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7576 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7577 hold the corresponding uninitialized symbols,
7578 * pic16_allocProcessorRegister: registers have explicit marked the
7580 * pic16_allocInternalRegister: registers are explicit marked as
7582 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7583 processing list, so bit registers were lost,
7586 * ralloc.h: added field 'accessBank' and original symbol operand
7587 in register definition,
7588 * removed the field isMapped from register definition,
7590 ** Several functions have been removed from various sources:
7591 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7592 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7593 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7594 pic16_assignRelocatableRegisters
7596 ** others have been introduced:
7597 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7598 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7600 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7602 * support/scripts/inc2h.pl: changed definition of BIT_AT
7603 to emit 'sbit at' instead of 'bit at'. This was a request.
7605 PIC16 port related preliminary changes:
7606 * gen.c: prefixed function popRegFromString with
7607 pic16_ and all references to it corrected
7608 * pcode.c: all pic16_pc_* hardware registers prefixed
7609 with underscore (_),
7610 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7611 * ralloc.c: newReg(): when register is REG_SFR then
7612 set address to rIdx,
7613 pic16_allocProcessorRegister(): marks register wasUsed=0
7614 pic16_writeUsedRegs(): added a call to assign processor
7615 registers via pic16_assignFixedRegisters
7617 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7619 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7620 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7621 variables in unused register banks. Also the SSEG is placed
7622 wherever there is enough space for it, and IDATA can be anywhere
7623 in internal RAM. For now compile using -Wl-Y[stack_size].
7624 The mem file is different for this option as well, since it
7625 makes no sense of talking about DSEG lenght.
7627 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7629 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7630 in certain cases, e.g. when ROM assignment, patch provided
7631 from Albert den Haan.
7633 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7872 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7874 * src/SDCCast.c (decorateType): disabled a transformation I added in
7875 revision 1.188 (access to fields of a structure at an absolute address);
7876 it breaks with bitfields, extern declarations, and gcse analysis.
7877 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7878 could be assigned through a pointer, so don't complain.
7879 * src/SDCCast.c (astErrors),
7881 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8519 support for standard C idiom of memory mapped variables; for
8520 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8521 to xdata int at 0x1234 tempvar = 1.
8522 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8523 provided by Akiya ISHIDA

8539 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8541 Fixed bug #621531 (const & volatile confusion in the type chain).
8542 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8543 refer to the const or volatile state of the pointer itself.

8634 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8635 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8636 fetching of the pointer
8637 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8638 copied from genNearPointerSet()
8639 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8640 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8641 If they pop r0/r1 they must be called in the opposite order than aopOp().

8654 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8656 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8657 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8658 type for bits was changed. It resulted in bit variables becoming
8659 global, which is not permitted in PIC 14 assembly output.
8661 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8663 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8676 A few small changes that speed up the peephole optimizer.
8680 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8682 Try to make the peephole optimizer smarter by maintaining
8683 an association between the assembly source code and the
8684 iCodes that originated them. Put this information to use
8685 with a new peephole rule condition "notVolatile" so that
8686 the rules can be aggressive yet still safe.
8691 * src/mcs51/peeph.def
8693 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8697 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8698 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8699 if the left or right operand symbols have the accuse flag set.
8701 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8703 Changed the type of the result of the ! (NOT) operator to char;
8704 previously it returned the same type as the source. This allows
8705 us to eliminate all the genFloatNot functions (all of its target
8706 implementations were very buggy) since !float can use the same
8709 * src/SDCCicode.c (ast2iCode): ! returns char

8718 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8719 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8720 during interrupts. Ensure WSAVE is located at a shared bank address.
8721 2. Fixed page selection in some places
8722 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8723 the registers name strings.
8724 4. Fixed "signed / unsigned compare" compiler warnings.
8725 5. The PIC port manages its own allocation of the general purpose
8726 registers, but makes no attempt to reuse them. As a result when
8727 compiling it soon runs out of general purpose registers. Some
8728 additional code was added to the files pcode.c and device.c to walk
8729 through the function call tree and rename the registers so that they
8739 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8740 genPlus() & genMinus() when the result is the same as left or right

8746 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8748 Made bitfield a distinct type from bit so that bitfields
8749 convert as per ANSI C and bits retain their traditional
8750 boolean style behaviour. Implemented bitfield support in
8758 * src/ds390/gen.c: bit v bitfield split
8759 * src/z80/gen.c: New support for bitfields
8760 * support/regression/tests/bitfields.c: reenabled z80,
8763 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8765 Rules 246.x, 247.x relate to bitfields, the others speed up
8766 access to xdata mapped I/O devices.
8768 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8770 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8772 Cleaned up genPackBits and genUnpackBits and added two helper
8773 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8774 for literal assignments in genPackBits (thanks to Frieder for
8780 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8782 Fixed bug #748310 (pointer to function type mishandled when the
8783 function name is omitted). Also fixed a SIGSEGV when a function
8784 attribute (reentrant, etc) is used on a non-function or on a
8785 function but misplaced before the parameter list.
8787 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8789 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8790 * support/Util/SDCCerr.h,
8791 * support/Util/SDCCerr.c: Added func attr misuse error msg
8793 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8795 Fixed bug #787649 by anonymous
8796 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8812 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8814 Made the constant following the "interrupt" keyword optional. If
8815 omitted, the function will not automatically be given an entry
8816 in the interrupt vector table (similar to #pragma NOIV, but
8817 less syntacticly kludgy). The interrupt number is also now
8818 range checked. Also fixed a bug in the high order bit example

8832 * src/SDCCicode.c (operandOperation): rewritten some ops
8833 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8834 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8836 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8837 be re-activated by defining REDUCE_LITERALS)
8838 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8839 unsigned, but are signed by default
8840 * src/SDCCval.c (constVal): rearranged
8841 * src/SDCCval.c (valMod): preliminary fix
8842 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9348 added if/endif conditional macros to remove options help
9349 messages from optionsTable when a port is not configured, added
9350 support for the PIc16 port in the ports table, when executing
9351 the compiler with no port specified on command line, a default
9352 port is selected with the new macro DEFAULT_PORT which is
9353 defined in port.h, in setDefaultOptions() linkOptions is removed
9354 from initialization assignment, since now it is a set,
9355 parseCmdLine uses setParseWithComma for linkOptions, in
9356 linkEdit() linkOptions are accessed with new function indexSet()
9357 which returns the i'th item of a set variable. See SDCCset.c, in
9358 linkEdit() when calling buildCmdLine(), added linkOptions as
9359 last argument. Now users can pass arguments to gplink via the
9360 -Wl option, main() uses pic16glue() to glue up pic16 programs

9374 gpasm complaining and test the linkage with gplink, _linkCmd and
9375 _asmCmd changed to be more gplink and gpasm friendly
9376 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9377 produced an error when parsed, peep rule 12 is added to utilize
9378 movff, but it is commented out since the pCode does not support
9379 yet a command with 2 address arguments
9381 2003-05-18 <johan AT balder>
9383 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9410 2003-05-11 Borut Razem <borut.razem AT siol.net>
9412 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10401 2003-01-07 <johan AT balder>
10403 * src/SDCCast.c (decorateType): fixed bug #600035
10405 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10406 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10407 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10408 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10409 * src/pic/pcode.c: outcommented unused variable to remove warnings

10416 2003-01-06 <johan AT balder>
10418 * src/SDCCicode.c: fixed array add
10420 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10421 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10422 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10424 2003-01-04 <johan AT balder>
10426 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10428 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10429 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10431 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10432 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10433 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10435 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10436 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10438 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10439 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10441 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10442 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10444 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10446 * in \sdcc\as\mcs51\ changed these files in order to create an
10447 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10448 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10449 following files to include the previous two files: aslink.dsp,
10450 Makefile.aslink, Makefile.bcc, and Makefile.in.
10452 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10453 .adb instead of .cdb
10455 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10457 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10458 value from option --iram-size.
10460 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10462 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10465 2002-09-18 <wiml AT hhhh.org>
10467 * SDCClrange.h: exposed setFromRange() and setToRange()
10468 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10469 packRegsForAccUse() (bug 542397)
10470 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10471 multiple times and emitting the fetch operations more than once
10472 added aopGetUsesAcc() function to allow binary operators to
10473 fetch their operands in the correct order; made genMinus() emit
10474 compact code for X = LITERAL - Y
10476 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10477 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10478 sprintf() in line 1267.
10480 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10481 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10484 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10485 Changes to aslink (All the changes are marked with 'JCF'):
10487 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10490 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10491 area BSEG. Also moves, if possible, the DATA area down into the internal
10492 ram so more space is available.
10494 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10497 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10498 not bytes. Function summary() which creates a memory usage summary
10499 file with extension .mem. Reports of overlaping stack and small stack
10500 size. If the space for the stack is less than 16 bytes aslink trows a
10503 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10504 the 8051. Option 'y' for memory summary output file.
10506 Changes to sdcc (All the changes are marked with 'JCF'):
10508 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10510 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10511 overlaying area for it (uses RegBankUsed[4]).
10513 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10514 bank zero as used by default. By default aslink locates the stack
10515 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10516 the creation of the .mem file. Delegates the allocation of data area
10517 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10518 the begining of the stack area to aslink.
10520 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10521 glue() in SDCCglue.c creates an area for it.
10523 2002-09-03 Borut Razem <borut.razem AT siol.net>
10524 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10525 sdcc/src/pic/glue.c:
10526 introduced atexit() handler for teporay files removal in case of
10527 errors, assertions, ...
10529 2002-08-29 Borut Razem <borut.razem AT siol.net>
10530 * sdcc/support/cpp2/auto-host_vc_in.h:
10531 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10532 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10533 Maybe there is a similar problem with BORLANDC? It should be checked!
10535 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10536 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10537 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10538 was not executed, and the compiler (cl) launched a warning:
10539 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10541 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10542 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10544 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10545 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10547 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10548 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10549 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10550 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10551 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10552 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10553 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10554 - added Release configuration in VS projects
10555 - review of compiler an linker options
10556 - VC .exe files are generated in bin_vc directory, not to interfere
10557 with binaries generated from other projects (cygwin, mingw, bcc ...)
10559 * sdcc/src/yacc.dsp: added
10561 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10562 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10563 and insert the version number definitions from .version
10565 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10567 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10568 added - genarate auto-host.h using auto-host_vc_in.h as template
10571 removed from CVS, generated automatically
10573 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10574 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10576 2002-08-11 Borut Razem <borut.razem AT siol.net>
10577 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10579 2002-08-10 Borut Razem <borut.razem AT siol.net>
10580 * src/SDCCmain.c (main):
10581 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10582 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10583 The consequence was that some temporary files were not removed.
10586 unification of code in functions tempfilename() and tempfile():
10587 function tempnam() is defined in Visual Studio 6.0 and .NET
10589 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10591 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10592 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10593 - removed compiler command line option /WX: Treats all warnings as errors
10594 - update a list of source files, included into the project
10596 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10597 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10598 changed project type to Generic Project so that can be correcly converted to VS.NET project
10600 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10602 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10604 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10606 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10607 added return 0 statements after assert() to make compiler happy
10609 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10610 added newline in the def file to keep MSC compiler satisfied
10612 * sdcc/src/z80/gen.c:
10613 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10614 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10615 - solved MSC error in function aopDump()
10617 * sdcc_vc.h: define PREFIX as "\\sdcc"
10619 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10620 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10623 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10624 - Rewrote the register banking algorithm.
10625 - Added pCode live-range analysis to registers (for now, only non-used and
10626 singly-used registers optimized away)
10628 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10630 * 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.

10653 * src/z80/main.c: Added force callee saves for jaune.
10655 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10657 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10659 2002-03-28 Johan Knol <johan AT balder>
10661 * src/SDCCval.c: fixed bug #532436
10663 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10665 Added "char *Processor" field to the port structure.
10668 Added -p option. Allows port dependent processor to be specified.
10671 Initialized the new field char *Processor field to NULL in all ports
10674 Compiler generated registers for interrupt context saving
10675 were not getting allocated.
10677 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10680 Fixed left shift. Will promote the left side of a left shift
10681 if a) left shifting more than size of operand or b) when assigned
10682 to something size > size of left side
10684 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10686 tons of changes. Register allocation has been
10687 rewritten. Added customization for the various PICs. Flow
10688 analysis is restructured. ...
10690 * src/pic/device.h:
10693 * src/pic/device.c:
10694 Added. device.c is a PIC port hack to accomodate variations
10697 2002-03-13 Michael Hope <michaelh AT vroom>
10699 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10701 2002-03-04 johanknol <johanknol AT manik>
10703 * /src/SDCCval.c: fixed
10705 const unsigned char arr[][2] = { { 0, 1 } };
10706 t18.c:1: error: Initializer element is not constant

10792 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10794 * sdcc/src/SDCCloop.c:
10795 Previous fix was not good. basic blocks that have "break" or "return" are
10796 not really partof a loop , but live ranges used in these blocks should
10797 be live thru the entire loop, so set partOfLoop but don't add them to
10800 2002-02-21 <johan AT FRIJA>
10802 * src/SDCCcse.c: fixed bug #514308
10804 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10807 Fixed BUG #519583. If a conditional block ended in a return/break
10808 statement inside a loop, it was not being considered part of the loop.
10810 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10812 2002-02-10 Karl Bongers <karl AT turbobit.com>

10816 with lots of comments and notes.
10818 * device/examples/test2.c:
10819 Fix bug, "red" variable not being initialized(compiler complained).
10821 * device/examples/Makefile, examples/test3.c:
10822 Add Makefile in device/examples folder, compiles test3.c
10823 for use as a multiple module SDCDB test case.
10825 * sim/ucsim/cmd.src/cmdset.cc:
10826 Took out debug printfs in ucsim "next" command.
10828 * sim/ucsim/xa.src:
10829 Karl and Johan start ucsim XA support. Most dissassembly working,
10830 about 75% emulation done(plenty of work remaining).
10832 * sim/ucsim/z80.src:
10833 Add Z80 support to ucsim, add test-ucz80 regression test,
10834 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10835 Notice z80 compiler fails on examples/test3.c/crc code.
10837 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10839 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10847 from a memory mapped port
10848 2) added __builtin_memcmp
10849 3) added __builtin_swapw swap bytes of a short
10851 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10852 1) handle multiple send & receives from register bank1
10853 2) ralloc can now allocate DPTR1 to some liveRanges
10855 * src/SDCCsymt.c, src/SDCCsymt.h:
10856 changes to handle multiple sends & receives
10858 * src/SDCCptropt.h:
10859 added some pointer arithmetic optimization
10861 * src/SDCCptropt.c:
10862 added some pointer arithmetic optimizations but not stable yet so not
