599 Enabled VPATH feature: changed nearly all Makefiles (149 files).
600 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
602 One basic decision: e.g. src/clean.mk includes further files. In order
603 to make this work there are two solutions:
604 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
605 run configure on them. This way they can use
606 'include $(srcdir)/port-clean.mk'
607 - always include clean.mk by the Makefile at the same level. To avoid
608 that `make clean` tries to include and build Makefile.dep the
609 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
610 implemented, because now even `make uninstall` doesn't create
611 Makefile.in. clean.mk could be eliminated by pasting it in
614 * debugger/mcs51/Makefile.in: build own objects from library sources
615 (SLIB, SDCC) in current directory
617 * configure, configure.in: renamed --disable-device-lib-build in
618 --disable-device-lib; added --enable-doc, the required tools are
619 searched by configure; added result message; the toolchain for the
620 belonging ports are now only built, if the port is enabled.
622 * support/regression/*: all output is written in directory gen, because
623 the fwk and ports directories don't livet in the build tree using vpath
625 * doc/sdccman.lyx: renamed --disable-device-lib-build to
626 --disable-device-lib, added --enable-doc, added section VPATH
628 * sim/ucsim/configure.in,
629 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
630 z80 are enabled by default
632 2006-04-24 Raphael Neider <rneider AT web.de>
634 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
635 to config word, "pic14_"-prefixed some extern functions
636 (pic14_emitConfigWord): emit __config directive(s) if assignment to
637 config word has been found
638 * src/pic/device.h: added prototypes
639 * src/pic/pcode.c: added "pic14_"-prefix where needed

950 allocating functions mark all registers as free. This eliminates some
951 side effects resulting from peephole parser done earlier in the backbone

1003 2006-03-06 Borut Razem <borut.razem AT siol.net>
1005 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1006 made the linker quiet
1008 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1011 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1012 which dumps before the function entry point a data byte which represents
1013 the number of the local variables used by the specified function, added
1014 'xinst' for initial support for Extended Instruction Support,
1015 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1016 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1017 port->fun_prefix anymore (may change later),
1018 (genFunction, genEndFunction): do not store/restore local registers for
1019 _main (this should take care the --main-return command line option in
1021 (genOr): removed some legacy pic-port instructions,
1022 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1023 performing operations with SFR's causes data to be written more than
1024 once to each SFR. Perhaps SFRs should be handled in special cases...
1025 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to

1033 (commented out for reference), didn't account for some registers which
1034 were left marked 'not free' after a pointer operation. The change
1035 reduces register usage a lot in some cases

3393 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3395 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3397 * device/lib/printf_large.c: removed inline assembly for portability and
3398 readability. Use printf_fast if speed or size are more important.
3399 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3400 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3402 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3404 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3405 prevent compiler warning
3407 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3409 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3410 moved to level 0 and declared as static. Also they are explicit
3411 placed in access bank. This was necessery because some times they
3412 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3413 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3414 optimizations. Currently only compare to unsigned char is implemented,
3415 * src/pic16/gen.c: added fReturnIdx array,
3416 * (struct resolvedIfx) is moved to gen.h and made public,
3417 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3418 * (aopForSym): added an optimization to directly store in stack of
3419 the operand of a SEND iCode,
3420 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3421 but as registers instead (AOP_REG) using the fReturnIdx array,
3422 * (pic16_freeAsmop): remove the freed register from the
3423 _G.sregsAlloc field,
3424 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3425 a compare of 'WREG',
3426 * (pic16_popGetTempRegCond): changed function prototype, now
3427 function takes also a bitVector argument v which holds the current
3428 set of registers that are allocated for stack access by aopForSym,
3429 registers allocated in aopForSym for accessing stack symbols are not
3430 any more part of the functions usedRegs field,
3431 * (genCall): some times aopOp is called for a stack variable to be
3432 send, aopForSym might perform the push, if this is true make sure
3433 that genCall doesn't push the variable twice by testing _G.resDirect,
3434 * (genFunction): changed testing for unspecified interrupt number
3435 from 256 to INTNO_UNSPEC,
3436 * modified selection scheme of frame pointer generation. Previously
3437 if function did use local registers a frame pointer was generated,
3438 now a frame pointer is generated only if function has arguments
3439 (that need PLUSW2 register access), or has stack arguments, or the
3440 compiler is not instructed to omit the frame pointer,
3441 * (genEndFunction): before restoring local registers that were saved
3442 in the function preamble, also restore the registers that *might*
3443 have been allocated for stack access,
3444 * (genRet): removed some old comments,
3445 * (genCmp, the active (RN's) version): added a call to the
3446 pic16_genCmp_special function to perform the compare with a more
3447 robust and optimized way,
3448 * (genInline): a feature has been added in inline code generation,
3449 which allows a wildcard variable substitution when writing inline
3450 assembly. Code is incomplete and experimental therefore undocumented,
3451 * (genCast): changed order of aopOp for result and right to allow
3452 aopForSym to directly load the result if possible,
3453 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3454 perform an optimized compare on some selected special occasions,
3455 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3456 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3457 generate an IVT any more,
3458 * src/pic16/main.c (pic16_optionsTable): added command line option
3460 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3461 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3463 * src/pic16/NOTES: Raphael Neider added in list of active developers
3464 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3465 jumptable_end to prevent bug #,
3466 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3467 inCond and outCond fields,
3468 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3469 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3470 turn off register spilling,
3471 * (packRegsForOneUse): synced with other ports' versions although it
3472 is not used currently,
3473 * (pic16_packRegisters): added an optimization while reading
3474 structure bitfields, some registers may be saved (malloc code is
3475 decreased by 80 bytes)

4121 Adding support for replacing ljmps with sjmps in jumptables
4122 generated for switch statements. For now you need to set the
4123 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4124 Now 4 algorithms for mcs51 jumptable generation are used:
4125 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4126 addresses loaded pc-relative for up to 112 cases and stack-pushing
4127 target addresses loaded with offset from dptr for up to 256 cases.

4157 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4159 * added libc directory. The current version of LibC contains string
4160 functions, ctype functions and macros and some functions of the
4161 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4162 be extensively tested in the future. Standard disclaimer here.
4163 Library is not automatically build yet. But one can build it by
4164 invoking 'make' inside the libc directory.

4175 * (pic16_storeForReturn): optimized return of 0,
4176 * (genCmp): experimental code for new genCmp which uses PIC18's
4177 special compare&skip instructions. Initial tests fail some times
4178 with variables grater than 1 byte in size, so new code is disabled,
4179 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4181 * (genCast): began a fix to optimize the casting of a bit to another
4182 bit, now assigning a bitfield to another bitfield will fail, sorry,

4190 * (isBankInstruction): modified to return 0 for no banking instruction,
4191 and 1 for banking instruction,
4192 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4193 caused stop processing pCodes after a inline assembly block,
4194 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4196 registers when it shouldn't,
4197 * src/pic16/ralloc.c (allocReg): add preliminary support for
4198 supporting a limited set of temporary registers,
4200 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7208 loaded with the linker search paths (-L arguments) and the libraries
7209 to be linked with the current source (-l arguments). Changes
7210 currently will affect only the pic16 port.
7211 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7212 include path the port specific paths and port specific libraries,
7213 * gplink command now contains the $3 argument,
7214 * src/pic16/device.h,

7231 Documenting changes from previous commits.
7232 * configure.in (version 1.56),
7233 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7234 when generating output files to configure the pic16 library,
7235 but now I've commented it out, since gputils aren't installed in the
7236 SF compile farm, so library won't compile
7238 * device/lib/Makefile.in (version 1.56): initially I've added in
7239 target 'all' the prerequestive 'model-pic16' so it compiled the
7240 pic16 library, but now I've commented it out for the same reasons
7242 * added targets 'model-pic16' and 'objects-pic16' to compile the
7244 * added target 'port-specific-objects-pic16' to handle the
7245 generated libraries and copy them into the build/ directory
7246 * added target 'clean-intermediate-pic16' to clean intermediate
7247 files into pic16 directory
7248 * in target 'installdirs' added line to create directory pic16 in

7252 added lines to copy all header files to installation path,
7253 * in target 'installdirs' added line create directory for pic16
7254 headers in the installation path

7486 * as/mcs51/lkarea.c: Fixed gcc warnings
7488 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7490 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
7492 * support/valdiag/tests/overflow.c: added
7493 * src/SDCCast.c (decorateType),
7494 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7495 LEFT_OP (left shift)
7497 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7499 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7500 (default behaviour).
7502 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7504 A python script to validate compiler diagnostic messages. It can be
7505 used to verify that sdcc complains about bad c source code and
7506 gives a good location of the error.
7507 * support/valdiag/Makefile,
7508 * support/valdiag/valdiag.py,
7509 * support/valdiag/tests/*
7511 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7513 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7514 * src/SDCCsymt.c (newEnumType),
7516 * support/Util/SDCCerr.c,
7517 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7519 * support/regression/tests/enum.c: added test for enum values that
7520 require at least 2 bytes of storage.
7522 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7524 * src/common.h: added ifndef/define/endif macros
7525 around the header file.
7526 Bug reported from Jesus Calvino-Fraga
7528 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7530 * sdcc.spec: updated
7531 * device/include/Makefile.in: don't install CVS directories
7532 * device/lib/Makefile.in: added removal of CVS directories after install
7533 * doc/Makefile: fixed install, added local_icons
7534 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7535 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7536 * src/ds390/gen.c (genRightShift): fixed bug #870788
7537 * src/SDCCast.c (decorateType): fixed bug #870781
7539 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7541 PIC16 port related changes:
7542 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7543 added variable stackPos,
7545 * gen.c: genCall, assignResultValue: added support for
7546 pushing/retrieving function parameters to/from stack,
7547 genFunction,genEndFunction: setup stack frame for the
7549 genAddrOf: will be changed according to bug 863624
7551 * added files genutils.c and genutils.h which contain gen*
7552 debugged and optimised functions extracted from gen.c
7554 * glue.c: added variable 'externs' which holds extern symbols,
7555 pic16emitRegularMap: is modified to properly handle relocatable
7556 symbols under the new scheme,
7557 pic16createInterruptVect: is modified
7558 pic16printPublics: is modified to emit 'global' assembler directives,
7559 added pic16_printExterns to print extern symbols,
7560 pic16glue: initializes stack/frame pointer in the beginning of
7561 the assembly output. Temporary hack, will be corrected later,
7562 because gplink yet does not support stack and SDCC does not
7563 yet support a type of crt0.o object to create the final binary.
7565 * Removed many lines that contain 8051 legacy code.
7566 * The code is finally placed under a 'code' directive.
7567 * Added port specific options.
7569 * _process_pragma: simplified since now we do not need *special*
7570 include file to define SFR registers. But a separate header
7571 will be needed. This will be developed later.
7572 * _pic16_parseOptions: added, parses port specific options:
7573 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7574 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7575 --preplace-udata-with=
7577 * _pic16_setDefaultOptions: modified to initialize section names,
7578 but hack is temporarly out of order since it needs improvement.
7579 * _pic16_genAssemblerPreamble: configuration words are emitted by
7580 their address instead of their name. This part is incomplete and
7581 supports only the 18Fxx2 devices. Other devices will emit an error
7582 during assembly since they do not contain the same set of config
7584 * _pic16_genIVT: is modified,
7586 * pcode.c: added definitions for some hardware registers that are needed
7588 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7589 All PCI entries are updated. Now LFSR is supported.
7590 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7591 * added pic16_newpCodeOpLit2 to support instructions with
7592 two literal arguments
7593 * pic16_pCode2str: corrected code that emits assembler instructions
7594 with two literal operands and those that have an access bit modifier
7595 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7596 this fixes a bug which caused some labels to be lost, when an
7597 assembler directive was added, i.e. banksel,
7598 * pic16_FixRegisterBanking: improved logic that causes the insertion
7600 * InlineFunction: functions that are called once, are not any more
7601 inlined. This can be a port option in the future,
7603 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7605 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7606 hold the corresponding uninitialized symbols,
7607 * pic16_allocProcessorRegister: registers have explicit marked the
7609 * pic16_allocInternalRegister: registers are explicit marked as
7611 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7612 processing list, so bit registers were lost,
7615 * ralloc.h: added field 'accessBank' and original symbol operand
7616 in register definition,
7617 * removed the field isMapped from register definition,
7619 ** Several functions have been removed from various sources:
7620 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7621 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7622 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7623 pic16_assignRelocatableRegisters
7625 ** others have been introduced:
7626 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7627 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7629 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7631 * support/scripts/inc2h.pl: changed definition of BIT_AT
7632 to emit 'sbit at' instead of 'bit at'. This was a request.
7634 PIC16 port related preliminary changes:
7635 * gen.c: prefixed function popRegFromString with
7636 pic16_ and all references to it corrected
7637 * pcode.c: all pic16_pc_* hardware registers prefixed
7638 with underscore (_),
7639 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7640 * ralloc.c: newReg(): when register is REG_SFR then
7641 set address to rIdx,
7642 pic16_allocProcessorRegister(): marks register wasUsed=0
7643 pic16_writeUsedRegs(): added a call to assign processor
7644 registers via pic16_assignFixedRegisters
7646 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7648 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7649 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7650 variables in unused register banks. Also the SSEG is placed
7651 wherever there is enough space for it, and IDATA can be anywhere
7652 in internal RAM. For now compile using -Wl-Y[stack_size].
7653 The mem file is different for this option as well, since it
7654 makes no sense of talking about DSEG lenght.
7656 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7658 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7659 in certain cases, e.g. when ROM assignment, patch provided
7660 from Albert den Haan.
7662 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7805 * src/mcs51/peephole.def,
7806 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7818 multiply defined with mismatching "at" address.
7820 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7822 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

7901 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7903 * src/SDCCast.c (decorateType): disabled a transformation I added in
7904 revision 1.188 (access to fields of a structure at an absolute address);
7905 it breaks with bitfields, extern declarations, and gcse analysis.
7906 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7907 could be assigned through a pointer, so don't complain.
7908 * src/SDCCast.c (astErrors),
7910 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8547 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8548 support for standard C idiom of memory mapped variables; for
8549 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8550 to xdata int at 0x1234 tempvar = 1.
8551 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8552 provided by Akiya ISHIDA

8568 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8570 Fixed bug #621531 (const & volatile confusion in the type chain).
8571 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8572 refer to the const or volatile state of the pointer itself.

8637 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8638 pcoderegs.h, ralloc.c, ralloc.h
8639 * main.c: added top header and GPL license notice

8663 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8664 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8665 fetching of the pointer
8666 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8667 copied from genNearPointerSet()
8668 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8669 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8670 If they pop r0/r1 they must be called in the opposite order than aopOp().
8671 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8672 (resp. --stack-auto), prepared for --xstack

8683 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8685 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8686 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8687 type for bits was changed. It resulted in bit variables becoming
8688 global, which is not permitted in PIC 14 assembly output.
8690 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8692 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8694 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8696 Z80 and MCS51 linkers complaint if a public symbol is defined

8705 A few small changes that speed up the peephole optimizer.
8709 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8711 Try to make the peephole optimizer smarter by maintaining
8712 an association between the assembly source code and the
8713 iCodes that originated them. Put this information to use
8714 with a new peephole rule condition "notVolatile" so that
8715 the rules can be aggressive yet still safe.
8720 * src/mcs51/peeph.def
8722 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8726 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8727 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8728 if the left or right operand symbols have the accuse flag set.
8730 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8732 Changed the type of the result of the ! (NOT) operator to char;
8733 previously it returned the same type as the source. This allows
8734 us to eliminate all the genFloatNot functions (all of its target
8735 implementations were very buggy) since !float can use the same
8738 * src/SDCCicode.c (ast2iCode): ! returns char

8740 * src/ds390/gen.c (genNot, genNotFloat),
8741 * src/z80/gen.c (genNot, genNotFloat),
8742 * src/pic/gen.c (genNot, genNotFloat),

8747 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8748 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8749 during interrupts. Ensure WSAVE is located at a shared bank address.
8750 2. Fixed page selection in some places
8751 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8752 the registers name strings.
8753 4. Fixed "signed / unsigned compare" compiler warnings.
8754 5. The PIC port manages its own allocation of the general purpose
8755 registers, but makes no attempt to reuse them. As a result when
8756 compiling it soon runs out of general purpose registers. Some
8757 additional code was added to the files pcode.c and device.c to walk
8758 through the function call tree and rename the registers so that they
8768 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8769 genPlus() & genMinus() when the result is the same as left or right
8771 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8775 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8777 Made bitfield a distinct type from bit so that bitfields
8778 convert as per ANSI C and bits retain their traditional
8779 boolean style behaviour. Implemented bitfield support in
8787 * src/ds390/gen.c: bit v bitfield split
8788 * src/z80/gen.c: New support for bitfields
8789 * support/regression/tests/bitfields.c: reenabled z80,
8792 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8794 Rules 246.x, 247.x relate to bitfields, the others speed up
8795 access to xdata mapped I/O devices.
8797 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8799 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8801 Cleaned up genPackBits and genUnpackBits and added two helper
8802 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8803 for literal assignments in genPackBits (thanks to Frieder for
8809 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8811 Fixed bug #748310 (pointer to function type mishandled when the
8812 function name is omitted). Also fixed a SIGSEGV when a function
8813 attribute (reentrant, etc) is used on a non-function or on a
8814 function but misplaced before the parameter list.
8816 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8818 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8819 * support/Util/SDCCerr.h,
8820 * support/Util/SDCCerr.c: Added func attr misuse error msg
8822 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8824 Fixed bug #787649 by anonymous
8825 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8841 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8843 Made the constant following the "interrupt" keyword optional. If
8844 omitted, the function will not automatically be given an entry
8845 in the interrupt vector table (similar to #pragma NOIV, but
8846 less syntacticly kludgy). The interrupt number is also now
8847 range checked. Also fixed a bug in the high order bit example

8861 * src/SDCCicode.c (operandOperation): rewritten some ops
8862 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8863 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8865 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8866 be re-activated by defining REDUCE_LITERALS)
8867 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8868 unsigned, but are signed by default
8869 * src/SDCCval.c (constVal): rearranged
8870 * src/SDCCval.c (valMod): preliminary fix
8871 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8913 constants are unsigned; added recognition of "u" flag for unsigned
8914 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8915 * src/SDCCval.c (valDiv, valMod): fixed signdness
8916 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8917 signedness of modulo, left and right shift

9377 added if/endif conditional macros to remove options help
9378 messages from optionsTable when a port is not configured, added
9379 support for the PIc16 port in the ports table, when executing
9380 the compiler with no port specified on command line, a default
9381 port is selected with the new macro DEFAULT_PORT which is
9382 defined in port.h, in setDefaultOptions() linkOptions is removed
9383 from initialization assignment, since now it is a set,
9384 parseCmdLine uses setParseWithComma for linkOptions, in
9385 linkEdit() linkOptions are accessed with new function indexSet()
9386 which returns the i'th item of a set variable. See SDCCset.c, in
9387 linkEdit() when calling buildCmdLine(), added linkOptions as
9388 last argument. Now users can pass arguments to gplink via the
9389 -Wl option, main() uses pic16glue() to glue up pic16 programs

9403 gpasm complaining and test the linkage with gplink, _linkCmd and
9404 _asmCmd changed to be more gplink and gpasm friendly
9405 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9406 produced an error when parsed, peep rule 12 is added to utilize
9407 movff, but it is commented out since the pCode does not support
9408 yet a command with 2 address arguments
9410 2003-05-18 <johan AT balder>
9412 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9439 2003-05-11 Borut Razem <borut.razem AT siol.net>
9441 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9442 the path of bin directory, so that PATH is the only env. variable, which has to be set

10430 2003-01-07 <johan AT balder>
10432 * src/SDCCast.c (decorateType): fixed bug #600035
10434 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10435 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10436 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10437 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10438 * src/pic/pcode.c: outcommented unused variable to remove warnings

10445 2003-01-06 <johan AT balder>
10447 * src/SDCCicode.c: fixed array add
10449 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10450 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10451 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10453 2003-01-04 <johan AT balder>
10455 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10457 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10458 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10460 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10461 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10462 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10464 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10465 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10467 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10468 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10470 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10471 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10473 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10475 * in \sdcc\as\mcs51\ changed these files in order to create an
10476 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10477 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10478 following files to include the previous two files: aslink.dsp,
10479 Makefile.aslink, Makefile.bcc, and Makefile.in.
10481 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10482 .adb instead of .cdb
10484 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10486 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10487 value from option --iram-size.
10489 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10491 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10494 2002-09-18 <wiml AT hhhh.org>
10496 * SDCClrange.h: exposed setFromRange() and setToRange()
10497 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10498 packRegsForAccUse() (bug 542397)
10499 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10500 multiple times and emitting the fetch operations more than once
10501 added aopGetUsesAcc() function to allow binary operators to
10502 fetch their operands in the correct order; made genMinus() emit
10503 compact code for X = LITERAL - Y
10505 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10506 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10507 sprintf() in line 1267.
10509 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10510 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10513 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10514 Changes to aslink (All the changes are marked with 'JCF'):
10516 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10519 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10520 area BSEG. Also moves, if possible, the DATA area down into the internal
10521 ram so more space is available.
10523 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10526 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10527 not bytes. Function summary() which creates a memory usage summary
10528 file with extension .mem. Reports of overlaping stack and small stack
10529 size. If the space for the stack is less than 16 bytes aslink trows a
10532 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10533 the 8051. Option 'y' for memory summary output file.
10535 Changes to sdcc (All the changes are marked with 'JCF'):
10537 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10539 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10540 overlaying area for it (uses RegBankUsed[4]).
10542 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10543 bank zero as used by default. By default aslink locates the stack
10544 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10545 the creation of the .mem file. Delegates the allocation of data area
10546 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10547 the begining of the stack area to aslink.
10549 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10550 glue() in SDCCglue.c creates an area for it.
10552 2002-09-03 Borut Razem <borut.razem AT siol.net>
10553 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10554 sdcc/src/pic/glue.c:
10555 introduced atexit() handler for teporay files removal in case of
10556 errors, assertions, ...
10558 2002-08-29 Borut Razem <borut.razem AT siol.net>
10559 * sdcc/support/cpp2/auto-host_vc_in.h:
10560 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10561 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10562 Maybe there is a similar problem with BORLANDC? It should be checked!
10564 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10565 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10566 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10567 was not executed, and the compiler (cl) launched a warning:
10568 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10570 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10571 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10573 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10574 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10576 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10577 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10578 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10579 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10580 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10581 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10582 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10583 - added Release configuration in VS projects
10584 - review of compiler an linker options
10585 - VC .exe files are generated in bin_vc directory, not to interfere
10586 with binaries generated from other projects (cygwin, mingw, bcc ...)
10588 * sdcc/src/yacc.dsp: added
10590 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10591 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10592 and insert the version number definitions from .version
10594 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10596 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10597 added - genarate auto-host.h using auto-host_vc_in.h as template
10600 removed from CVS, generated automatically
10602 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10603 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10605 2002-08-11 Borut Razem <borut.razem AT siol.net>
10606 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10608 2002-08-10 Borut Razem <borut.razem AT siol.net>
10609 * src/SDCCmain.c (main):
10610 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10611 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10612 The consequence was that some temporary files were not removed.
10615 unification of code in functions tempfilename() and tempfile():
10616 function tempnam() is defined in Visual Studio 6.0 and .NET
10618 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10620 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10621 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10622 - removed compiler command line option /WX: Treats all warnings as errors
10623 - update a list of source files, included into the project
10625 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10626 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10627 changed project type to Generic Project so that can be correcly converted to VS.NET project
10629 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10631 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10633 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10635 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10636 added return 0 statements after assert() to make compiler happy
10638 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10639 added newline in the def file to keep MSC compiler satisfied
10641 * sdcc/src/z80/gen.c:
10642 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10643 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10644 - solved MSC error in function aopDump()
10646 * sdcc_vc.h: define PREFIX as "\\sdcc"
10648 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10649 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10652 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10653 - Rewrote the register banking algorithm.
10654 - Added pCode live-range analysis to registers (for now, only non-used and
10655 singly-used registers optimized away)
10657 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10659 * 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.

10682 * src/z80/main.c: Added force callee saves for jaune.
10684 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10686 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10688 2002-03-28 Johan Knol <johan AT balder>
10690 * src/SDCCval.c: fixed bug #532436
10692 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10694 Added "char *Processor" field to the port structure.
10697 Added -p option. Allows port dependent processor to be specified.
10700 Initialized the new field char *Processor field to NULL in all ports
10703 Compiler generated registers for interrupt context saving
10704 were not getting allocated.
10706 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10709 Fixed left shift. Will promote the left side of a left shift
10710 if a) left shifting more than size of operand or b) when assigned
10711 to something size > size of left side
10713 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10715 tons of changes. Register allocation has been
10716 rewritten. Added customization for the various PICs. Flow
10717 analysis is restructured. ...
10719 * src/pic/device.h:
10722 * src/pic/device.c:
10723 Added. device.c is a PIC port hack to accomodate variations
10726 2002-03-13 Michael Hope <michaelh AT vroom>
10728 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10730 2002-03-04 johanknol <johanknol AT manik>
10732 * /src/SDCCval.c: fixed
10734 const unsigned char arr[][2] = { { 0, 1 } };

10821 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10823 * sdcc/src/SDCCloop.c:
10824 Previous fix was not good. basic blocks that have "break" or "return" are
10825 not really partof a loop , but live ranges used in these blocks should
10826 be live thru the entire loop, so set partOfLoop but don't add them to
10829 2002-02-21 <johan AT FRIJA>
10831 * src/SDCCcse.c: fixed bug #514308
10833 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10836 Fixed BUG #519583. If a conditional block ended in a return/break
10837 statement inside a loop, it was not being considered part of the loop.
10839 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10841 2002-02-10 Karl Bongers <karl AT turbobit.com>

10847 * device/examples/test2.c:
10848 Fix bug, "red" variable not being initialized(compiler complained).
10850 * device/examples/Makefile, examples/test3.c:
10851 Add Makefile in device/examples folder, compiles test3.c
10852 for use as a multiple module SDCDB test case.
10854 * sim/ucsim/cmd.src/cmdset.cc:
10855 Took out debug printfs in ucsim "next" command.
10857 * sim/ucsim/xa.src:
10858 Karl and Johan start ucsim XA support. Most dissassembly working,
10859 about 75% emulation done(plenty of work remaining).
10861 * sim/ucsim/z80.src:
10862 Add Z80 support to ucsim, add test-ucz80 regression test,
10863 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
