591 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
593 Enabled VPATH feature: changed nearly all Makefiles (149 files).
594 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
596 One basic decision: e.g. src/clean.mk includes further files. In order
597 to make this work there are two solutions:
598 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
599 run configure on them. This way they can use
600 'include $(srcdir)/port-clean.mk'
601 - always include clean.mk by the Makefile at the same level. To avoid
602 that `make clean` tries to include and build Makefile.dep the
603 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
604 implemented, because now even `make uninstall` doesn't create
605 Makefile.in. clean.mk could be eliminated by pasting it in
608 * debugger/mcs51/Makefile.in: build own objects from library sources
609 (SLIB, SDCC) in current directory
611 * configure, configure.in: renamed --disable-device-lib-build in
612 --disable-device-lib; added --enable-doc, the required tools are
613 searched by configure; added result message; the toolchain for the
614 belonging ports are now only built, if the port is enabled.
616 * support/regression/*: all output is written in directory gen, because
617 the fwk and ports directories don't livet in the build tree using vpath
619 * doc/sdccman.lyx: renamed --disable-device-lib-build to
620 --disable-device-lib, added --enable-doc, added section VPATH
622 * sim/ucsim/configure.in,
623 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
624 z80 are enabled by default
626 2006-04-24 Raphael Neider <rneider AT web.de>
628 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
629 to config word, "pic14_"-prefixed some extern functions
630 (pic14_emitConfigWord): emit __config directive(s) if assignment to
631 config word has been found
632 * src/pic/device.h: added prototypes
633 * src/pic/pcode.c: added "pic14_"-prefix where needed
634 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
636 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

650 fixes #1469504 and #1474602,
651 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

941 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
942 call to allocReg, not by manually allocating a new one,

997 2006-03-06 Borut Razem <borut.razem AT siol.net>
999 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1000 made the linker quiet
1002 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1004 * src/pic16/gen.c (genPcall): fixed bug #1443644
1005 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1006 which dumps before the function entry point a data byte which represents
1007 the number of the local variables used by the specified function, added
1008 'xinst' for initial support for Extended Instruction Support,
1009 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1010 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1011 port->fun_prefix anymore (may change later),

1015 (genOr): removed some legacy pic-port instructions,
1016 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1017 performing operations with SFR's causes data to be written more than

1026 (deassignLRs): *** perhaps the most important change, old 'for' code
1027 (commented out for reference), didn't account for some registers which
1028 were left marked 'not free' after a pointer operation. The change
1029 reduces register usage a lot in some cases

3305 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3306 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3307 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3308 always available in leading double underscore form. The C99 support is

3387 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3389 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3391 * device/lib/printf_large.c: removed inline assembly for portability and
3392 readability. Use printf_fast if speed or size are more important.
3393 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3394 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3396 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3398 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3399 prevent compiler warning
3401 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3403 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3404 moved to level 0 and declared as static. Also they are explicit
3405 placed in access bank. This was necessery because some times they
3406 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3407 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3408 optimizations. Currently only compare to unsigned char is implemented,
3409 * src/pic16/gen.c: added fReturnIdx array,
3410 * (struct resolvedIfx) is moved to gen.h and made public,
3411 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3412 * (aopForSym): added an optimization to directly store in stack of
3413 the operand of a SEND iCode,
3414 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3415 but as registers instead (AOP_REG) using the fReturnIdx array,
3416 * (pic16_freeAsmop): remove the freed register from the
3417 _G.sregsAlloc field,
3418 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3419 a compare of 'WREG',
3420 * (pic16_popGetTempRegCond): changed function prototype, now
3421 function takes also a bitVector argument v which holds the current
3422 set of registers that are allocated for stack access by aopForSym,
3423 registers allocated in aopForSym for accessing stack symbols are not
3424 any more part of the functions usedRegs field,
3425 * (genCall): some times aopOp is called for a stack variable to be
3426 send, aopForSym might perform the push, if this is true make sure
3427 that genCall doesn't push the variable twice by testing _G.resDirect,
3428 * (genFunction): changed testing for unspecified interrupt number
3429 from 256 to INTNO_UNSPEC,
3430 * modified selection scheme of frame pointer generation. Previously
3431 if function did use local registers a frame pointer was generated,
3432 now a frame pointer is generated only if function has arguments
3433 (that need PLUSW2 register access), or has stack arguments, or the
3434 compiler is not instructed to omit the frame pointer,
3435 * (genEndFunction): before restoring local registers that were saved
3436 in the function preamble, also restore the registers that *might*
3437 have been allocated for stack access,
3438 * (genRet): removed some old comments,
3439 * (genCmp, the active (RN's) version): added a call to the
3440 pic16_genCmp_special function to perform the compare with a more
3441 robust and optimized way,
3442 * (genInline): a feature has been added in inline code generation,
3443 which allows a wildcard variable substitution when writing inline
3444 assembly. Code is incomplete and experimental therefore undocumented,
3445 * (genCast): changed order of aopOp for result and right to allow
3446 aopForSym to directly load the result if possible,
3447 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3448 perform an optimized compare on some selected special occasions,
3449 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3450 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3451 generate an IVT any more,
3452 * src/pic16/main.c (pic16_optionsTable): added command line option
3454 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3455 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3457 * src/pic16/NOTES: Raphael Neider added in list of active developers
3458 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3459 jumptable_end to prevent bug #,
3460 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3461 inCond and outCond fields,
3462 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3463 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3464 turn off register spilling,
3465 * (packRegsForOneUse): synced with other ports' versions although it
3466 is not used currently,
3467 * (pic16_packRegisters): added an optimization while reading
3468 structure bitfields, some registers may be saved (malloc code is
3469 decreased by 80 bytes)
3471 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3473 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3474 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3475 this can be optimized more?
3477 2005-03-10 Raphael Neider <rneider AT web.de>

4115 Adding support for replacing ljmps with sjmps in jumptables
4116 generated for switch statements. For now you need to set the
4117 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4118 Now 4 algorithms for mcs51 jumptable generation are used:
4119 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4120 addresses loaded pc-relative for up to 112 cases and stack-pushing
4121 target addresses loaded with offset from dptr for up to 256 cases.

4151 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4153 * added libc directory. The current version of LibC contains string
4154 functions, ctype functions and macros and some functions of the
4155 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4156 be extensively tested in the future. Standard disclaimer here.
4157 Library is not automatically build yet. But one can build it by
4158 invoking 'make' inside the libc directory.

4169 * (pic16_storeForReturn): optimized return of 0,
4170 * (genCmp): experimental code for new genCmp which uses PIC18's
4171 special compare&skip instructions. Initial tests fail some times
4172 with variables grater than 1 byte in size, so new code is disabled,
4173 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4175 * (genCast): began a fix to optimize the casting of a bit to another
4176 bit, now assigning a bitfield to another bitfield will fail, sorry,
4177 * src/pic16/main.c: disabled the use of lr-support feature,
4178 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4185 and 1 for banking instruction,
4186 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4187 caused stop processing pCodes after a inline assembly block,
4188 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4190 registers when it shouldn't,
4191 * src/pic16/ralloc.c (allocReg): add preliminary support for
4192 supporting a limited set of temporary registers,
4194 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4200 (genFunction): optimize RECEIVE iCodes in reentrant functions
4202 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7202 loaded with the linker search paths (-L arguments) and the libraries
7203 to be linked with the current source (-l arguments). Changes
7204 currently will affect only the pic16 port.
7205 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7206 include path the port specific paths and port specific libraries,
7207 * gplink command now contains the $3 argument,

7225 Documenting changes from previous commits.
7226 * configure.in (version 1.56),
7227 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7228 when generating output files to configure the pic16 library,
7229 but now I've commented it out, since gputils aren't installed in the
7230 SF compile farm, so library won't compile
7232 * device/lib/Makefile.in (version 1.56): initially I've added in
7233 target 'all' the prerequestive 'model-pic16' so it compiled the
7234 pic16 library, but now I've commented it out for the same reasons
7236 * added targets 'model-pic16' and 'objects-pic16' to compile the
7238 * added target 'port-specific-objects-pic16' to handle the
7239 generated libraries and copy them into the build/ directory
7240 * added target 'clean-intermediate-pic16' to clean intermediate
7241 files into pic16 directory
7242 * in target 'installdirs' added line to create directory pic16 in

7246 added lines to copy all header files to installation path,
7247 * in target 'installdirs' added line create directory for pic16
7248 headers in the installation path

7488 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7489 LEFT_OP (left shift)
7491 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7493 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7494 (default behaviour).
7496 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7498 A python script to validate compiler diagnostic messages. It can be
7499 used to verify that sdcc complains about bad c source code and
7500 gives a good location of the error.
7501 * support/valdiag/Makefile,
7502 * support/valdiag/valdiag.py,
7503 * support/valdiag/tests/*
7505 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7507 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7508 * src/SDCCsymt.c (newEnumType),
7510 * support/Util/SDCCerr.c,
7511 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7513 * support/regression/tests/enum.c: added test for enum values that
7514 require at least 2 bytes of storage.
7516 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7518 * src/common.h: added ifndef/define/endif macros
7519 around the header file.
7520 Bug reported from Jesus Calvino-Fraga
7522 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7524 * sdcc.spec: updated
7525 * device/include/Makefile.in: don't install CVS directories
7526 * device/lib/Makefile.in: added removal of CVS directories after install
7527 * doc/Makefile: fixed install, added local_icons
7528 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7529 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7530 * src/ds390/gen.c (genRightShift): fixed bug #870788
7531 * src/SDCCast.c (decorateType): fixed bug #870781
7533 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7535 PIC16 port related changes:
7536 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7537 added variable stackPos,
7539 * gen.c: genCall, assignResultValue: added support for
7540 pushing/retrieving function parameters to/from stack,
7541 genFunction,genEndFunction: setup stack frame for the
7543 genAddrOf: will be changed according to bug 863624
7545 * added files genutils.c and genutils.h which contain gen*
7546 debugged and optimised functions extracted from gen.c
7548 * glue.c: added variable 'externs' which holds extern symbols,
7549 pic16emitRegularMap: is modified to properly handle relocatable
7550 symbols under the new scheme,
7551 pic16createInterruptVect: is modified
7552 pic16printPublics: is modified to emit 'global' assembler directives,
7553 added pic16_printExterns to print extern symbols,
7554 pic16glue: initializes stack/frame pointer in the beginning of
7555 the assembly output. Temporary hack, will be corrected later,
7556 because gplink yet does not support stack and SDCC does not
7557 yet support a type of crt0.o object to create the final binary.
7559 * Removed many lines that contain 8051 legacy code.
7560 * The code is finally placed under a 'code' directive.
7561 * Added port specific options.
7563 * _process_pragma: simplified since now we do not need *special*
7564 include file to define SFR registers. But a separate header
7565 will be needed. This will be developed later.
7566 * _pic16_parseOptions: added, parses port specific options:
7567 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7568 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7569 --preplace-udata-with=
7571 * _pic16_setDefaultOptions: modified to initialize section names,
7572 but hack is temporarly out of order since it needs improvement.
7573 * _pic16_genAssemblerPreamble: configuration words are emitted by
7574 their address instead of their name. This part is incomplete and
7575 supports only the 18Fxx2 devices. Other devices will emit an error
7576 during assembly since they do not contain the same set of config
7578 * _pic16_genIVT: is modified,
7580 * pcode.c: added definitions for some hardware registers that are needed
7582 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7583 All PCI entries are updated. Now LFSR is supported.
7584 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7585 * added pic16_newpCodeOpLit2 to support instructions with
7586 two literal arguments
7587 * pic16_pCode2str: corrected code that emits assembler instructions
7588 with two literal operands and those that have an access bit modifier
7589 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7590 this fixes a bug which caused some labels to be lost, when an
7591 assembler directive was added, i.e. banksel,
7592 * pic16_FixRegisterBanking: improved logic that causes the insertion
7594 * InlineFunction: functions that are called once, are not any more
7595 inlined. This can be a port option in the future,
7597 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7599 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7600 hold the corresponding uninitialized symbols,
7601 * pic16_allocProcessorRegister: registers have explicit marked the
7603 * pic16_allocInternalRegister: registers are explicit marked as
7605 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7606 processing list, so bit registers were lost,
7609 * ralloc.h: added field 'accessBank' and original symbol operand
7610 in register definition,
7611 * removed the field isMapped from register definition,
7613 ** Several functions have been removed from various sources:
7614 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7615 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7616 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7617 pic16_assignRelocatableRegisters
7619 ** others have been introduced:
7620 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7621 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7623 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7625 * support/scripts/inc2h.pl: changed definition of BIT_AT
7626 to emit 'sbit at' instead of 'bit at'. This was a request.
7628 PIC16 port related preliminary changes:
7629 * gen.c: prefixed function popRegFromString with
7630 pic16_ and all references to it corrected
7631 * pcode.c: all pic16_pc_* hardware registers prefixed
7632 with underscore (_),
7633 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7634 * ralloc.c: newReg(): when register is REG_SFR then
7635 set address to rIdx,
7636 pic16_allocProcessorRegister(): marks register wasUsed=0
7637 pic16_writeUsedRegs(): added a call to assign processor
7638 registers via pic16_assignFixedRegisters
7640 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7642 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7643 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7644 variables in unused register banks. Also the SSEG is placed
7645 wherever there is enough space for it, and IDATA can be anywhere
7646 in internal RAM. For now compile using -Wl-Y[stack_size].
7647 The mem file is different for this option as well, since it
7648 makes no sense of talking about DSEG lenght.
7650 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7652 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7653 in certain cases, e.g. when ROM assignment, patch provided
7654 from Albert den Haan.
7656 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7895 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7897 * src/SDCCast.c (decorateType): disabled a transformation I added in
7898 revision 1.188 (access to fields of a structure at an absolute address);
7899 it breaks with bitfields, extern declarations, and gcse analysis.
7900 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7901 could be assigned through a pointer, so don't complain.
7902 * src/SDCCast.c (astErrors),
7904 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8539 * src/SDCCsymt.c (sclsFromPtr),
8541 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8542 support for standard C idiom of memory mapped variables; for
8543 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8544 to xdata int at 0x1234 tempvar = 1.
8545 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8546 provided by Akiya ISHIDA

8562 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8564 Fixed bug #621531 (const & volatile confusion in the type chain).
8565 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8566 refer to the const or volatile state of the pointer itself.

8631 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8632 pcoderegs.h, ralloc.c, ralloc.h
8633 * main.c: added top header and GPL license notice
8634 * pcode.c: fixed the if-conditional warning
8636 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>

8657 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8658 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8659 fetching of the pointer
8660 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8661 copied from genNearPointerSet()
8662 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8663 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8664 If they pop r0/r1 they must be called in the opposite order than aopOp().
8665 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8666 (resp. --stack-auto), prepared for --xstack

8677 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8679 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8680 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8681 type for bits was changed. It resulted in bit variables becoming
8682 global, which is not permitted in PIC 14 assembly output.
8684 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8686 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8699 A few small changes that speed up the peephole optimizer.
8703 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8705 Try to make the peephole optimizer smarter by maintaining
8706 an association between the assembly source code and the
8707 iCodes that originated them. Put this information to use
8708 with a new peephole rule condition "notVolatile" so that
8709 the rules can be aggressive yet still safe.
8714 * src/mcs51/peeph.def
8716 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8720 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8721 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8722 if the left or right operand symbols have the accuse flag set.
8724 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8726 Changed the type of the result of the ! (NOT) operator to char;
8727 previously it returned the same type as the source. This allows
8728 us to eliminate all the genFloatNot functions (all of its target
8729 implementations were very buggy) since !float can use the same
8732 * src/SDCCicode.c (ast2iCode): ! returns char

8734 * src/ds390/gen.c (genNot, genNotFloat),
8735 * src/z80/gen.c (genNot, genNotFloat),
8736 * src/pic/gen.c (genNot, genNotFloat),

8741 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8742 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8743 during interrupts. Ensure WSAVE is located at a shared bank address.
8744 2. Fixed page selection in some places
8745 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8746 the registers name strings.
8747 4. Fixed "signed / unsigned compare" compiler warnings.
8748 5. The PIC port manages its own allocation of the general purpose
8749 registers, but makes no attempt to reuse them. As a result when
8750 compiling it soon runs out of general purpose registers. Some
8751 additional code was added to the files pcode.c and device.c to walk
8752 through the function call tree and rename the registers so that they
8762 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8763 genPlus() & genMinus() when the result is the same as left or right
8765 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8769 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8771 Made bitfield a distinct type from bit so that bitfields
8772 convert as per ANSI C and bits retain their traditional
8773 boolean style behaviour. Implemented bitfield support in
8781 * src/ds390/gen.c: bit v bitfield split
8782 * src/z80/gen.c: New support for bitfields
8783 * support/regression/tests/bitfields.c: reenabled z80,
8786 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8788 Rules 246.x, 247.x relate to bitfields, the others speed up
8789 access to xdata mapped I/O devices.
8791 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8793 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8795 Cleaned up genPackBits and genUnpackBits and added two helper
8796 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8797 for literal assignments in genPackBits (thanks to Frieder for
8803 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8805 Fixed bug #748310 (pointer to function type mishandled when the
8806 function name is omitted). Also fixed a SIGSEGV when a function
8807 attribute (reentrant, etc) is used on a non-function or on a
8808 function but misplaced before the parameter list.
8810 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8812 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8813 * support/Util/SDCCerr.h,
8814 * support/Util/SDCCerr.c: Added func attr misuse error msg
8816 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8818 Fixed bug #787649 by anonymous
8819 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8835 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8837 Made the constant following the "interrupt" keyword optional. If
8838 omitted, the function will not automatically be given an entry
8839 in the interrupt vector table (similar to #pragma NOIV, but
8840 less syntacticly kludgy). The interrupt number is also now
8841 range checked. Also fixed a bug in the high order bit example

8852 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8854 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8855 * src/SDCCicode.c (operandOperation): rewritten some ops
8856 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8857 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8859 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8860 be re-activated by defining REDUCE_LITERALS)
8861 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8862 unsigned, but are signed by default
8863 * src/SDCCval.c (constVal): rearranged
8864 * src/SDCCval.c (valMod): preliminary fix
8865 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8907 constants are unsigned; added recognition of "u" flag for unsigned
8908 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8909 * src/SDCCval.c (valDiv, valMod): fixed signdness
8910 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8911 signedness of modulo, left and right shift

8966 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
8968 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
8969 there, while the mantissa of a double is "only" 53 bits wide.

9371 added if/endif conditional macros to remove options help
9372 messages from optionsTable when a port is not configured, added
9373 support for the PIc16 port in the ports table, when executing
9374 the compiler with no port specified on command line, a default
9375 port is selected with the new macro DEFAULT_PORT which is
9376 defined in port.h, in setDefaultOptions() linkOptions is removed
9377 from initialization assignment, since now it is a set,
9378 parseCmdLine uses setParseWithComma for linkOptions, in
9379 linkEdit() linkOptions are accessed with new function indexSet()
9380 which returns the i'th item of a set variable. See SDCCset.c, in
9381 linkEdit() when calling buildCmdLine(), added linkOptions as
9382 last argument. Now users can pass arguments to gplink via the
9383 -Wl option, main() uses pic16glue() to glue up pic16 programs

9397 gpasm complaining and test the linkage with gplink, _linkCmd and
9398 _asmCmd changed to be more gplink and gpasm friendly
9399 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9400 produced an error when parsed, peep rule 12 is added to utilize
9401 movff, but it is commented out since the pCode does not support
9402 yet a command with 2 address arguments
9404 2003-05-18 <johan AT balder>
9406 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9433 2003-05-11 Borut Razem <borut.razem AT siol.net>
9435 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10424 2003-01-07 <johan AT balder>
10426 * src/SDCCast.c (decorateType): fixed bug #600035
10428 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
10429 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10430 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10431 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10432 * src/pic/pcode.c: outcommented unused variable to remove warnings

10439 2003-01-06 <johan AT balder>
10441 * src/SDCCicode.c: fixed array add
10443 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10444 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10445 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10447 2003-01-04 <johan AT balder>
10449 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10451 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10452 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10454 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10455 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10456 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10458 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10459 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10461 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10462 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10464 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10465 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10467 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10469 * in \sdcc\as\mcs51\ changed these files in order to create an
10470 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10471 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10472 following files to include the previous two files: aslink.dsp,
10473 Makefile.aslink, Makefile.bcc, and Makefile.in.
10475 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10476 .adb instead of .cdb
10478 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10480 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10481 value from option --iram-size.
10483 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10485 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10488 2002-09-18 <wiml AT hhhh.org>
10490 * SDCClrange.h: exposed setFromRange() and setToRange()
10491 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10492 packRegsForAccUse() (bug 542397)
10493 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10494 multiple times and emitting the fetch operations more than once
10495 added aopGetUsesAcc() function to allow binary operators to
10496 fetch their operands in the correct order; made genMinus() emit
10497 compact code for X = LITERAL - Y
10499 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10500 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10501 sprintf() in line 1267.
10503 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10504 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10507 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10508 Changes to aslink (All the changes are marked with 'JCF'):
10510 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10513 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10514 area BSEG. Also moves, if possible, the DATA area down into the internal
10515 ram so more space is available.
10517 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10520 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10521 not bytes. Function summary() which creates a memory usage summary
10522 file with extension .mem. Reports of overlaping stack and small stack
10523 size. If the space for the stack is less than 16 bytes aslink trows a
10526 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10527 the 8051. Option 'y' for memory summary output file.
10529 Changes to sdcc (All the changes are marked with 'JCF'):
10531 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10533 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10534 overlaying area for it (uses RegBankUsed[4]).
10536 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10537 bank zero as used by default. By default aslink locates the stack
10538 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10539 the creation of the .mem file. Delegates the allocation of data area
10540 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10541 the begining of the stack area to aslink.
10543 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10544 glue() in SDCCglue.c creates an area for it.
10546 2002-09-03 Borut Razem <borut.razem AT siol.net>
10547 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10548 sdcc/src/pic/glue.c:
10549 introduced atexit() handler for teporay files removal in case of
10550 errors, assertions, ...
10552 2002-08-29 Borut Razem <borut.razem AT siol.net>
10553 * sdcc/support/cpp2/auto-host_vc_in.h:
10554 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10555 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10556 Maybe there is a similar problem with BORLANDC? It should be checked!
10558 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10559 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10560 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10561 was not executed, and the compiler (cl) launched a warning:
10562 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10564 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10565 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10567 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10568 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10570 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10571 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10572 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10573 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10574 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10575 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10576 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10577 - added Release configuration in VS projects
10578 - review of compiler an linker options
10579 - VC .exe files are generated in bin_vc directory, not to interfere
10580 with binaries generated from other projects (cygwin, mingw, bcc ...)
10582 * sdcc/src/yacc.dsp: added
10584 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10585 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10586 and insert the version number definitions from .version
10588 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10590 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10591 added - genarate auto-host.h using auto-host_vc_in.h as template
10594 removed from CVS, generated automatically
10596 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10597 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10599 2002-08-11 Borut Razem <borut.razem AT siol.net>
10600 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10602 2002-08-10 Borut Razem <borut.razem AT siol.net>
10603 * src/SDCCmain.c (main):
10604 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10605 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10606 The consequence was that some temporary files were not removed.
10609 unification of code in functions tempfilename() and tempfile():
10610 function tempnam() is defined in Visual Studio 6.0 and .NET
10612 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10614 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10615 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10616 - removed compiler command line option /WX: Treats all warnings as errors
10617 - update a list of source files, included into the project
10619 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10620 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10621 changed project type to Generic Project so that can be correcly converted to VS.NET project
10623 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10625 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10627 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10629 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10630 added return 0 statements after assert() to make compiler happy
10632 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10633 added newline in the def file to keep MSC compiler satisfied
10635 * sdcc/src/z80/gen.c:
10636 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10637 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10638 - solved MSC error in function aopDump()
10640 * sdcc_vc.h: define PREFIX as "\\sdcc"
10642 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10643 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10646 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10647 - Rewrote the register banking algorithm.
10648 - Added pCode live-range analysis to registers (for now, only non-used and
10649 singly-used registers optimized away)
10651 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10653 * 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.

10672 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10674 * src/z80/peeph.def: Added transpose redundent load rule.
10676 * src/z80/main.c: Added force callee saves for jaune.
10678 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10680 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10682 2002-03-28 Johan Knol <johan AT balder>
10684 * src/SDCCval.c: fixed bug #532436
10686 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10688 Added "char *Processor" field to the port structure.
10691 Added -p option. Allows port dependent processor to be specified.
10694 Initialized the new field char *Processor field to NULL in all ports
10697 Compiler generated registers for interrupt context saving
10698 were not getting allocated.
10700 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10703 Fixed left shift. Will promote the left side of a left shift
10704 if a) left shifting more than size of operand or b) when assigned
10705 to something size > size of left side
10707 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10709 tons of changes. Register allocation has been
10710 rewritten. Added customization for the various PICs. Flow
10711 analysis is restructured. ...
10713 * src/pic/device.h:
10716 * src/pic/device.c:
10717 Added. device.c is a PIC port hack to accomodate variations
10720 2002-03-13 Michael Hope <michaelh AT vroom>
10722 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10724 2002-03-04 johanknol <johanknol AT manik>
10726 * /src/SDCCval.c: fixed
10728 const unsigned char arr[][2] = { { 0, 1 } };
10729 t18.c:1: error: Initializer element is not constant

10815 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10817 * sdcc/src/SDCCloop.c:
10818 Previous fix was not good. basic blocks that have "break" or "return" are
10819 not really partof a loop , but live ranges used in these blocks should
10820 be live thru the entire loop, so set partOfLoop but don't add them to
10823 2002-02-21 <johan AT FRIJA>
10825 * src/SDCCcse.c: fixed bug #514308
10827 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10830 Fixed BUG #519583. If a conditional block ended in a return/break
10831 statement inside a loop, it was not being considered part of the loop.
10833 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10835 2002-02-10 Karl Bongers <karl AT turbobit.com>

10839 with lots of comments and notes.
10841 * device/examples/test2.c:
10842 Fix bug, "red" variable not being initialized(compiler complained).
10844 * device/examples/Makefile, examples/test3.c:
10845 Add Makefile in device/examples folder, compiles test3.c
10846 for use as a multiple module SDCDB test case.
10848 * sim/ucsim/cmd.src/cmdset.cc:
10849 Took out debug printfs in ucsim "next" command.
10851 * sim/ucsim/xa.src:
10852 Karl and Johan start ucsim XA support. Most dissassembly working,
10853 about 75% emulation done(plenty of work remaining).
10855 * sim/ucsim/z80.src:
10856 Add Z80 support to ucsim, add test-ucz80 regression test,
10857 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10858 Notice z80 compiler fails on examples/test3.c/crc code.
10860 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10862 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
10863 Added support for --parms-in-bank1
