589 Enabled VPATH feature: changed nearly all Makefiles (149 files).
590 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
592 One basic decision: e.g. src/clean.mk includes further files. In order
593 to make this work there are two solutions:
594 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
595 run configure on them. This way they can use
596 'include $(srcdir)/port-clean.mk'
597 - always include clean.mk by the Makefile at the same level. To avoid
598 that `make clean` tries to include and build Makefile.dep the
599 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
600 implemented, because now even `make uninstall` doesn't create
601 Makefile.in. clean.mk could be eliminated by pasting it in
604 * debugger/mcs51/Makefile.in: build own objects from library sources
605 (SLIB, SDCC) in current directory
607 * configure, configure.in: renamed --disable-device-lib-build in
608 --disable-device-lib; added --enable-doc, the required tools are
609 searched by configure; added result message; the toolchain for the
610 belonging ports are now only built, if the port is enabled.
612 * support/regression/*: all output is written in directory gen, because
613 the fwk and ports directories don't livet in the build tree using vpath
615 * doc/sdccman.lyx: renamed --disable-device-lib-build to
616 --disable-device-lib, added --enable-doc, added section VPATH
618 * sim/ucsim/configure.in,
619 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
620 z80 are enabled by default
622 2006-04-24 Raphael Neider <rneider AT web.de>
624 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
625 to config word, "pic14_"-prefixed some extern functions
626 (pic14_emitConfigWord): emit __config directive(s) if assignment to
627 config word has been found
628 * src/pic/device.h: added prototypes
629 * src/pic/pcode.c: added "pic14_"-prefix where needed

632 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

915 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
917 * src/.version: increased version number to 2.5.5
918 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
919 linking is done manually in pic16 port's _linkEdit,
920 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
921 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

937 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
938 call to allocReg, not by manually allocating a new one,
939 (pic16_assignRegisters): now before going through the register
940 allocating functions mark all registers as free. This eliminates some
941 side effects resulting from peephole parser done earlier in the backbone

996 made the linker quiet
998 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1000 * src/pic16/gen.c (genPcall): fixed bug #1443644
1001 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1002 which dumps before the function entry point a data byte which represents
1003 the number of the local variables used by the specified function, added
1004 'xinst' for initial support for Extended Instruction Support,
1005 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1006 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1007 port->fun_prefix anymore (may change later),

1020 --extended or -y for Extended Instruction Support,
1021 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1022 (deassignLRs): *** perhaps the most important change, old 'for' code
1023 (commented out for reference), didn't account for some registers which
1024 were left marked 'not free' after a pointer operation. The change
1025 reduces register usage a lot in some cases

3300 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3301 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3302 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3303 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3304 always available in leading double underscore form. The C99 support is

3383 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3385 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3387 * device/lib/printf_large.c: removed inline assembly for portability and
3388 readability. Use printf_fast if speed or size are more important.
3389 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3390 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3392 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3394 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3395 prevent compiler warning
3397 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3399 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3400 moved to level 0 and declared as static. Also they are explicit
3401 placed in access bank. This was necessery because some times they
3402 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3403 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3404 optimizations. Currently only compare to unsigned char is implemented,
3405 * src/pic16/gen.c: added fReturnIdx array,
3406 * (struct resolvedIfx) is moved to gen.h and made public,
3407 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3408 * (aopForSym): added an optimization to directly store in stack of
3409 the operand of a SEND iCode,
3410 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3411 but as registers instead (AOP_REG) using the fReturnIdx array,
3412 * (pic16_freeAsmop): remove the freed register from the
3413 _G.sregsAlloc field,
3414 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3415 a compare of 'WREG',
3416 * (pic16_popGetTempRegCond): changed function prototype, now
3417 function takes also a bitVector argument v which holds the current
3418 set of registers that are allocated for stack access by aopForSym,
3419 registers allocated in aopForSym for accessing stack symbols are not
3420 any more part of the functions usedRegs field,
3421 * (genCall): some times aopOp is called for a stack variable to be
3422 send, aopForSym might perform the push, if this is true make sure
3423 that genCall doesn't push the variable twice by testing _G.resDirect,
3424 * (genFunction): changed testing for unspecified interrupt number
3425 from 256 to INTNO_UNSPEC,
3426 * modified selection scheme of frame pointer generation. Previously
3427 if function did use local registers a frame pointer was generated,
3428 now a frame pointer is generated only if function has arguments
3429 (that need PLUSW2 register access), or has stack arguments, or the
3430 compiler is not instructed to omit the frame pointer,
3431 * (genEndFunction): before restoring local registers that were saved
3432 in the function preamble, also restore the registers that *might*
3433 have been allocated for stack access,
3434 * (genRet): removed some old comments,
3435 * (genCmp, the active (RN's) version): added a call to the
3436 pic16_genCmp_special function to perform the compare with a more
3437 robust and optimized way,
3438 * (genInline): a feature has been added in inline code generation,
3439 which allows a wildcard variable substitution when writing inline
3440 assembly. Code is incomplete and experimental therefore undocumented,
3441 * (genCast): changed order of aopOp for result and right to allow
3442 aopForSym to directly load the result if possible,
3443 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3444 perform an optimized compare on some selected special occasions,
3445 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3446 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3447 generate an IVT any more,
3448 * src/pic16/main.c (pic16_optionsTable): added command line option
3450 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3451 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3453 * src/pic16/NOTES: Raphael Neider added in list of active developers
3454 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3455 jumptable_end to prevent bug #,
3456 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3457 inCond and outCond fields,
3458 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3459 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3460 turn off register spilling,
3461 * (packRegsForOneUse): synced with other ports' versions although it
3462 is not used currently,
3463 * (pic16_packRegisters): added an optimization while reading
3464 structure bitfields, some registers may be saved (malloc code is
3465 decreased by 80 bytes)
3467 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3469 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3470 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3471 this can be optimized more?
3473 2005-03-10 Raphael Neider <rneider AT web.de>
3475 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3476 genNearPointerGet): (hopefully) fixed access to bitfields via

4111 Adding support for replacing ljmps with sjmps in jumptables
4112 generated for switch statements. For now you need to set the
4113 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4114 Now 4 algorithms for mcs51 jumptable generation are used:
4115 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4116 addresses loaded pc-relative for up to 112 cases and stack-pushing
4117 target addresses loaded with offset from dptr for up to 256 cases.

4147 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4149 * added libc directory. The current version of LibC contains string
4150 functions, ctype functions and macros and some functions of the
4151 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4152 be extensively tested in the future. Standard disclaimer here.
4153 Library is not automatically build yet. But one can build it by
4154 invoking 'make' inside the libc directory.

4165 * (pic16_storeForReturn): optimized return of 0,
4166 * (genCmp): experimental code for new genCmp which uses PIC18's
4167 special compare&skip instructions. Initial tests fail some times
4168 with variables grater than 1 byte in size, so new code is disabled,
4169 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4171 * (genCast): began a fix to optimize the casting of a bit to another
4172 bit, now assigning a bitfield to another bitfield will fail, sorry,

4180 * (isBankInstruction): modified to return 0 for no banking instruction,
4181 and 1 for banking instruction,
4182 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4183 caused stop processing pCodes after a inline assembly block,
4184 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4185 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4186 registers when it shouldn't,
4187 * src/pic16/ralloc.c (allocReg): add preliminary support for
4188 supporting a limited set of temporary registers,
4190 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4196 (genFunction): optimize RECEIVE iCodes in reentrant functions
4198 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7198 loaded with the linker search paths (-L arguments) and the libraries
7199 to be linked with the current source (-l arguments). Changes
7200 currently will affect only the pic16 port.
7201 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7202 include path the port specific paths and port specific libraries,
7203 * gplink command now contains the $3 argument,

7221 Documenting changes from previous commits.
7222 * configure.in (version 1.56),
7223 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7224 when generating output files to configure the pic16 library,
7225 but now I've commented it out, since gputils aren't installed in the
7226 SF compile farm, so library won't compile
7228 * device/lib/Makefile.in (version 1.56): initially I've added in
7229 target 'all' the prerequestive 'model-pic16' so it compiled the
7230 pic16 library, but now I've commented it out for the same reasons
7232 * added targets 'model-pic16' and 'objects-pic16' to compile the
7234 * added target 'port-specific-objects-pic16' to handle the
7235 generated libraries and copy them into the build/ directory
7236 * added target 'clean-intermediate-pic16' to clean intermediate
7237 files into pic16 directory
7238 * in target 'installdirs' added line to create directory pic16 in

7242 added lines to copy all header files to installation path,
7243 * in target 'installdirs' added line create directory for pic16
7244 headers in the installation path

7487 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7489 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7490 (default behaviour).
7492 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7494 A python script to validate compiler diagnostic messages. It can be
7495 used to verify that sdcc complains about bad c source code and
7496 gives a good location of the error.
7497 * support/valdiag/Makefile,
7498 * support/valdiag/valdiag.py,
7499 * support/valdiag/tests/*
7501 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7503 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7504 * src/SDCCsymt.c (newEnumType),
7506 * support/Util/SDCCerr.c,
7507 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7509 * support/regression/tests/enum.c: added test for enum values that
7510 require at least 2 bytes of storage.
7512 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7514 * src/common.h: added ifndef/define/endif macros
7515 around the header file.
7516 Bug reported from Jesus Calvino-Fraga
7518 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7520 * sdcc.spec: updated
7521 * device/include/Makefile.in: don't install CVS directories
7522 * device/lib/Makefile.in: added removal of CVS directories after install
7523 * doc/Makefile: fixed install, added local_icons
7524 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7525 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7526 * src/ds390/gen.c (genRightShift): fixed bug #870788
7527 * src/SDCCast.c (decorateType): fixed bug #870781
7529 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7531 PIC16 port related changes:
7532 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7533 added variable stackPos,
7535 * gen.c: genCall, assignResultValue: added support for
7536 pushing/retrieving function parameters to/from stack,
7537 genFunction,genEndFunction: setup stack frame for the
7539 genAddrOf: will be changed according to bug 863624
7541 * added files genutils.c and genutils.h which contain gen*
7542 debugged and optimised functions extracted from gen.c
7544 * glue.c: added variable 'externs' which holds extern symbols,
7545 pic16emitRegularMap: is modified to properly handle relocatable
7546 symbols under the new scheme,
7547 pic16createInterruptVect: is modified
7548 pic16printPublics: is modified to emit 'global' assembler directives,
7549 added pic16_printExterns to print extern symbols,
7550 pic16glue: initializes stack/frame pointer in the beginning of
7551 the assembly output. Temporary hack, will be corrected later,
7552 because gplink yet does not support stack and SDCC does not
7553 yet support a type of crt0.o object to create the final binary.
7555 * Removed many lines that contain 8051 legacy code.
7556 * The code is finally placed under a 'code' directive.
7557 * Added port specific options.
7559 * _process_pragma: simplified since now we do not need *special*
7560 include file to define SFR registers. But a separate header
7561 will be needed. This will be developed later.
7562 * _pic16_parseOptions: added, parses port specific options:
7563 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7564 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7565 --preplace-udata-with=
7567 * _pic16_setDefaultOptions: modified to initialize section names,
7568 but hack is temporarly out of order since it needs improvement.
7569 * _pic16_genAssemblerPreamble: configuration words are emitted by
7570 their address instead of their name. This part is incomplete and
7571 supports only the 18Fxx2 devices. Other devices will emit an error
7572 during assembly since they do not contain the same set of config
7574 * _pic16_genIVT: is modified,
7576 * pcode.c: added definitions for some hardware registers that are needed
7578 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7579 All PCI entries are updated. Now LFSR is supported.
7580 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7581 * added pic16_newpCodeOpLit2 to support instructions with
7582 two literal arguments
7583 * pic16_pCode2str: corrected code that emits assembler instructions
7584 with two literal operands and those that have an access bit modifier
7585 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7586 this fixes a bug which caused some labels to be lost, when an
7587 assembler directive was added, i.e. banksel,
7588 * pic16_FixRegisterBanking: improved logic that causes the insertion
7590 * InlineFunction: functions that are called once, are not any more
7591 inlined. This can be a port option in the future,
7593 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7595 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7596 hold the corresponding uninitialized symbols,
7597 * pic16_allocProcessorRegister: registers have explicit marked the
7599 * pic16_allocInternalRegister: registers are explicit marked as
7601 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7602 processing list, so bit registers were lost,
7605 * ralloc.h: added field 'accessBank' and original symbol operand
7606 in register definition,
7607 * removed the field isMapped from register definition,
7609 ** Several functions have been removed from various sources:
7610 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7611 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7612 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7613 pic16_assignRelocatableRegisters
7615 ** others have been introduced:
7616 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7617 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7619 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7621 * support/scripts/inc2h.pl: changed definition of BIT_AT
7622 to emit 'sbit at' instead of 'bit at'. This was a request.
7624 PIC16 port related preliminary changes:
7625 * gen.c: prefixed function popRegFromString with
7626 pic16_ and all references to it corrected
7627 * pcode.c: all pic16_pc_* hardware registers prefixed
7628 with underscore (_),
7629 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7630 * ralloc.c: newReg(): when register is REG_SFR then
7631 set address to rIdx,
7632 pic16_allocProcessorRegister(): marks register wasUsed=0
7633 pic16_writeUsedRegs(): added a call to assign processor
7634 registers via pic16_assignFixedRegisters
7636 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7638 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7639 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7640 variables in unused register banks. Also the SSEG is placed
7641 wherever there is enough space for it, and IDATA can be anywhere
7642 in internal RAM. For now compile using -Wl-Y[stack_size].
7643 The mem file is different for this option as well, since it
7644 makes no sense of talking about DSEG lenght.
7646 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7648 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7649 in certain cases, e.g. when ROM assignment, patch provided
7650 from Albert den Haan.
7652 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7891 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7893 * src/SDCCast.c (decorateType): disabled a transformation I added in
7894 revision 1.188 (access to fields of a structure at an absolute address);
7895 it breaks with bitfields, extern declarations, and gcse analysis.
7896 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7897 could be assigned through a pointer, so don't complain.
7898 * src/SDCCast.c (astErrors),
7900 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8535 * src/SDCCsymt.c (sclsFromPtr),
8537 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8538 support for standard C idiom of memory mapped variables; for
8539 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8540 to xdata int at 0x1234 tempvar = 1.
8541 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8542 provided by Akiya ISHIDA

8558 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8560 Fixed bug #621531 (const & volatile confusion in the type chain).
8561 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8562 refer to the const or volatile state of the pointer itself.

8627 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8628 pcoderegs.h, ralloc.c, ralloc.h
8629 * main.c: added top header and GPL license notice
8630 * pcode.c: fixed the if-conditional warning
8632 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8634 * device/lib/_mullong.c: replaced int by short for gcc
8636 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8643 aren't part of the nRegs tally.
8645 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8647 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

8653 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8654 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8655 fetching of the pointer
8656 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8657 copied from genNearPointerSet()
8658 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8659 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8660 If they pop r0/r1 they must be called in the opposite order than aopOp().
8661 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8662 (resp. --stack-auto), prepared for --xstack

8673 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8675 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8676 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8677 type for bits was changed. It resulted in bit variables becoming
8678 global, which is not permitted in PIC 14 assembly output.
8680 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8682 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8684 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8686 Z80 and MCS51 linkers complaint if a public symbol is defined

8695 A few small changes that speed up the peephole optimizer.
8699 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8701 Try to make the peephole optimizer smarter by maintaining
8702 an association between the assembly source code and the
8703 iCodes that originated them. Put this information to use
8704 with a new peephole rule condition "notVolatile" so that
8705 the rules can be aggressive yet still safe.
8710 * src/mcs51/peeph.def
8712 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8716 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8717 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8718 if the left or right operand symbols have the accuse flag set.
8720 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8722 Changed the type of the result of the ! (NOT) operator to char;
8723 previously it returned the same type as the source. This allows
8724 us to eliminate all the genFloatNot functions (all of its target
8725 implementations were very buggy) since !float can use the same
8728 * src/SDCCicode.c (ast2iCode): ! returns char
8729 * src/mcs51/gen.c (genNot, genNotFloat),
8730 * src/ds390/gen.c (genNot, genNotFloat),
8731 * src/z80/gen.c (genNot, genNotFloat),
8732 * src/pic/gen.c (genNot, genNotFloat),

8735 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8737 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8738 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8739 during interrupts. Ensure WSAVE is located at a shared bank address.
8740 2. Fixed page selection in some places
8741 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8742 the registers name strings.
8743 4. Fixed "signed / unsigned compare" compiler warnings.
8744 5. The PIC port manages its own allocation of the general purpose
8745 registers, but makes no attempt to reuse them. As a result when
8746 compiling it soon runs out of general purpose registers. Some
8747 additional code was added to the files pcode.c and device.c to walk
8748 through the function call tree and rename the registers so that they
8758 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8759 genPlus() & genMinus() when the result is the same as left or right
8761 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8765 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8767 Made bitfield a distinct type from bit so that bitfields
8768 convert as per ANSI C and bits retain their traditional
8769 boolean style behaviour. Implemented bitfield support in
8777 * src/ds390/gen.c: bit v bitfield split
8778 * src/z80/gen.c: New support for bitfields
8779 * support/regression/tests/bitfields.c: reenabled z80,
8782 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8784 Rules 246.x, 247.x relate to bitfields, the others speed up
8785 access to xdata mapped I/O devices.
8787 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8789 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8791 Cleaned up genPackBits and genUnpackBits and added two helper
8792 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8793 for literal assignments in genPackBits (thanks to Frieder for
8799 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8801 Fixed bug #748310 (pointer to function type mishandled when the
8802 function name is omitted). Also fixed a SIGSEGV when a function
8803 attribute (reentrant, etc) is used on a non-function or on a
8804 function but misplaced before the parameter list.
8806 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8808 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8809 * support/Util/SDCCerr.h,
8810 * support/Util/SDCCerr.c: Added func attr misuse error msg
8812 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8814 Fixed bug #787649 by anonymous
8815 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8831 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8833 Made the constant following the "interrupt" keyword optional. If
8834 omitted, the function will not automatically be given an entry
8835 in the interrupt vector table (similar to #pragma NOIV, but
8836 less syntacticly kludgy). The interrupt number is also now
8837 range checked. Also fixed a bug in the high order bit example

8845 * support/Util/SDCCerr.h
8848 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8850 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8851 * src/SDCCicode.c (operandOperation): rewritten some ops
8852 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8853 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8855 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8856 be re-activated by defining REDUCE_LITERALS)
8857 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8858 unsigned, but are signed by default
8859 * src/SDCCval.c (constVal): rearranged
8860 * src/SDCCval.c (valMod): preliminary fix
8861 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8903 constants are unsigned; added recognition of "u" flag for unsigned
8904 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8905 * src/SDCCval.c (valDiv, valMod): fixed signdness
8906 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8907 signedness of modulo, left and right shift

9366 * src/SDCCmain.c: linkOptions is changed to set *,
9367 added if/endif conditional macros to remove options help
9368 messages from optionsTable when a port is not configured, added
9369 support for the PIc16 port in the ports table, when executing
9370 the compiler with no port specified on command line, a default
9371 port is selected with the new macro DEFAULT_PORT which is
9372 defined in port.h, in setDefaultOptions() linkOptions is removed
9373 from initialization assignment, since now it is a set,
9374 parseCmdLine uses setParseWithComma for linkOptions, in
9375 linkEdit() linkOptions are accessed with new function indexSet()
9376 which returns the i'th item of a set variable. See SDCCset.c, in
9377 linkEdit() when calling buildCmdLine(), added linkOptions as
9378 last argument. Now users can pass arguments to gplink via the
9379 -Wl option, main() uses pic16glue() to glue up pic16 programs

9393 gpasm complaining and test the linkage with gplink, _linkCmd and
9394 _asmCmd changed to be more gplink and gpasm friendly
9395 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9396 produced an error when parsed, peep rule 12 is added to utilize
9397 movff, but it is commented out since the pCode does not support
9398 yet a command with 2 address arguments
9400 2003-05-18 <johan AT balder>
9402 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9429 2003-05-11 Borut Razem <borut.razem AT siol.net>
9431 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9432 the path of bin directory, so that PATH is the only env. variable, which has to be set

10422 * src/SDCCast.c (decorateType): fixed bug #600035
10424 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10425 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10426 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10427 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

10435 2003-01-06 <johan AT balder>
10437 * src/SDCCicode.c: fixed array add
10439 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10440 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10441 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10443 2003-01-04 <johan AT balder>
10445 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10447 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10448 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10450 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10451 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10452 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10454 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10455 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10457 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10458 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10460 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10461 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10463 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10465 * in \sdcc\as\mcs51\ changed these files in order to create an
10466 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10467 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10468 following files to include the previous two files: aslink.dsp,
10469 Makefile.aslink, Makefile.bcc, and Makefile.in.
10471 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10472 .adb instead of .cdb
10474 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10476 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10477 value from option --iram-size.
10479 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10481 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10484 2002-09-18 <wiml AT hhhh.org>
10486 * SDCClrange.h: exposed setFromRange() and setToRange()
10487 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10488 packRegsForAccUse() (bug 542397)
10489 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10490 multiple times and emitting the fetch operations more than once
10491 added aopGetUsesAcc() function to allow binary operators to
10492 fetch their operands in the correct order; made genMinus() emit
10493 compact code for X = LITERAL - Y
10495 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10496 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10497 sprintf() in line 1267.
10499 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10500 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10503 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10504 Changes to aslink (All the changes are marked with 'JCF'):
10506 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10509 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10510 area BSEG. Also moves, if possible, the DATA area down into the internal
10511 ram so more space is available.
10513 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10516 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10517 not bytes. Function summary() which creates a memory usage summary
10518 file with extension .mem. Reports of overlaping stack and small stack
10519 size. If the space for the stack is less than 16 bytes aslink trows a
10522 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10523 the 8051. Option 'y' for memory summary output file.
10525 Changes to sdcc (All the changes are marked with 'JCF'):
10527 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10529 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10530 overlaying area for it (uses RegBankUsed[4]).
10532 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10533 bank zero as used by default. By default aslink locates the stack
10534 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10535 the creation of the .mem file. Delegates the allocation of data area
10536 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10537 the begining of the stack area to aslink.
10539 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10540 glue() in SDCCglue.c creates an area for it.
10542 2002-09-03 Borut Razem <borut.razem AT siol.net>
10543 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10544 sdcc/src/pic/glue.c:
10545 introduced atexit() handler for teporay files removal in case of
10546 errors, assertions, ...
10548 2002-08-29 Borut Razem <borut.razem AT siol.net>
10549 * sdcc/support/cpp2/auto-host_vc_in.h:
10550 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10551 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10552 Maybe there is a similar problem with BORLANDC? It should be checked!
10554 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10555 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10556 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10557 was not executed, and the compiler (cl) launched a warning:
10558 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10560 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10561 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10563 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10564 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10566 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10567 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10568 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10569 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10570 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10571 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10572 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10573 - added Release configuration in VS projects
10574 - review of compiler an linker options
10575 - VC .exe files are generated in bin_vc directory, not to interfere
10576 with binaries generated from other projects (cygwin, mingw, bcc ...)
10578 * sdcc/src/yacc.dsp: added
10580 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10581 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10582 and insert the version number definitions from .version
10584 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10586 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10587 added - genarate auto-host.h using auto-host_vc_in.h as template
10590 removed from CVS, generated automatically
10592 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10593 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10595 2002-08-11 Borut Razem <borut.razem AT siol.net>
10596 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10598 2002-08-10 Borut Razem <borut.razem AT siol.net>
10599 * src/SDCCmain.c (main):
10600 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10601 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10602 The consequence was that some temporary files were not removed.
10605 unification of code in functions tempfilename() and tempfile():
10606 function tempnam() is defined in Visual Studio 6.0 and .NET
10608 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10610 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10611 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10612 - removed compiler command line option /WX: Treats all warnings as errors
10613 - update a list of source files, included into the project
10615 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10616 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10617 changed project type to Generic Project so that can be correcly converted to VS.NET project
10619 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10621 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10623 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10625 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10626 added return 0 statements after assert() to make compiler happy
10628 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10629 added newline in the def file to keep MSC compiler satisfied
10631 * sdcc/src/z80/gen.c:
10632 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10633 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10634 - solved MSC error in function aopDump()
10636 * sdcc_vc.h: define PREFIX as "\\sdcc"
10638 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10639 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10642 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10643 - Rewrote the register banking algorithm.
10644 - Added pCode live-range analysis to registers (for now, only non-used and
10645 singly-used registers optimized away)
10647 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10649 * 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.

10666 * device/lib/z80/printf.c (sprintf): Added.
10668 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10670 * src/z80/peeph.def: Added transpose redundent load rule.
10672 * src/z80/main.c: Added force callee saves for jaune.
10674 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10676 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10678 2002-03-28 Johan Knol <johan AT balder>
10680 * src/SDCCval.c: fixed bug #532436
10682 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10684 Added "char *Processor" field to the port structure.
10687 Added -p option. Allows port dependent processor to be specified.
10690 Initialized the new field char *Processor field to NULL in all ports
10693 Compiler generated registers for interrupt context saving
10694 were not getting allocated.
10696 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10699 Fixed left shift. Will promote the left side of a left shift
10700 if a) left shifting more than size of operand or b) when assigned
10701 to something size > size of left side
10703 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10705 tons of changes. Register allocation has been
10706 rewritten. Added customization for the various PICs. Flow
10707 analysis is restructured. ...
10709 * src/pic/device.h:
10712 * src/pic/device.c:
10713 Added. device.c is a PIC port hack to accomodate variations
10716 2002-03-13 Michael Hope <michaelh AT vroom>
10718 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10720 2002-03-04 johanknol <johanknol AT manik>
10722 * /src/SDCCval.c: fixed
10724 const unsigned char arr[][2] = { { 0, 1 } };
10725 t18.c:1: error: Initializer element is not constant

10811 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10813 * sdcc/src/SDCCloop.c:
10814 Previous fix was not good. basic blocks that have "break" or "return" are
10815 not really partof a loop , but live ranges used in these blocks should
10816 be live thru the entire loop, so set partOfLoop but don't add them to
10819 2002-02-21 <johan AT FRIJA>
10821 * src/SDCCcse.c: fixed bug #514308
10823 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10826 Fixed BUG #519583. If a conditional block ended in a return/break
10827 statement inside a loop, it was not being considered part of the loop.
10829 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10831 2002-02-10 Karl Bongers <karl AT turbobit.com>
10834 Fixed up SDCDB debugger somewhat. Updated debugger/README
10835 with lots of comments and notes.
10837 * device/examples/test2.c:
10838 Fix bug, "red" variable not being initialized(compiler complained).
10840 * device/examples/Makefile, examples/test3.c:
10841 Add Makefile in device/examples folder, compiles test3.c
10842 for use as a multiple module SDCDB test case.
10844 * sim/ucsim/cmd.src/cmdset.cc:
10845 Took out debug printfs in ucsim "next" command.
10847 * sim/ucsim/xa.src:
10848 Karl and Johan start ucsim XA support. Most dissassembly working,
10849 about 75% emulation done(plenty of work remaining).
10851 * sim/ucsim/z80.src:
10852 Add Z80 support to ucsim, add test-ucz80 regression test,
10853 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10854 Notice z80 compiler fails on examples/test3.c/crc code.
10856 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10858 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
10859 Added support for --parms-in-bank1
10861 * src/ds390/peeph.def:
10862 added a few more peephole optimzations
