582 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
584 Enabled VPATH feature: changed nearly all Makefiles (149 files).
585 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
587 One basic decision: e.g. src/clean.mk includes further files. In order
588 to make this work there are two solutions:
589 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
590 run configure on them. This way they can use
591 'include $(srcdir)/port-clean.mk'
592 - always include clean.mk by the Makefile at the same level. To avoid
593 that `make clean` tries to include and build Makefile.dep the
594 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
595 implemented, because now even `make uninstall` doesn't create
596 Makefile.in. clean.mk could be eliminated by pasting it in
599 * debugger/mcs51/Makefile.in: build own objects from library sources
600 (SLIB, SDCC) in current directory
602 * configure, configure.in: renamed --disable-device-lib-build in
603 --disable-device-lib; added --enable-doc, the required tools are
604 searched by configure; added result message; the toolchain for the
605 belonging ports are now only built, if the port is enabled.
607 * support/regression/*: all output is written in directory gen, because
608 the fwk and ports directories don't livet in the build tree using vpath
610 * doc/sdccman.lyx: renamed --disable-device-lib-build to
611 --disable-device-lib, added --enable-doc, added section VPATH
613 * sim/ucsim/configure.in,
614 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
615 z80 are enabled by default
617 2006-04-24 Raphael Neider <rneider AT web.de>
619 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
620 to config word, "pic14_"-prefixed some extern functions
621 (pic14_emitConfigWord): emit __config directive(s) if assignment to
622 config word has been found
623 * src/pic/device.h: added prototypes
624 * src/pic/pcode.c: added "pic14_"-prefix where needed
625 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
627 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
629 (pic14emitRegularMap): ignore config words,
630 (pic14createInterruptVect): moved generating __config directives away

640 registers that have not been assigned proper liveranges,
641 fixes #1469504 and #1474602,
642 (pCodeRegOptimizeRegUsage): fixed typo in comment

914 linking is done manually in pic16 port's _linkEdit,
915 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
916 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

990 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
991 made the linker quiet
993 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
995 * src/pic16/gen.c (genPcall): fixed bug #1443644
996 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag

998 the number of the local variables used by the specified function, added
999 'xinst' for initial support for Extended Instruction Support,
1000 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1001 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1002 port->fun_prefix anymore (may change later),

1015 --extended or -y for Extended Instruction Support,
1016 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1017 (deassignLRs): *** perhaps the most important change, old 'for' code
1018 (commented out for reference), didn't account for some registers which
1019 were left marked 'not free' after a pointer operation. The change
1020 reduces register usage a lot in some cases

3295 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3296 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3297 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3298 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3299 always available in leading double underscore form. The C99 support is

3378 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3380 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3382 * device/lib/printf_large.c: removed inline assembly for portability and
3383 readability. Use printf_fast if speed or size are more important.
3384 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3385 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3387 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3389 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3390 prevent compiler warning
3392 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3394 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3395 moved to level 0 and declared as static. Also they are explicit
3396 placed in access bank. This was necessery because some times they
3397 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3398 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3399 optimizations. Currently only compare to unsigned char is implemented,
3400 * src/pic16/gen.c: added fReturnIdx array,
3401 * (struct resolvedIfx) is moved to gen.h and made public,
3402 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3403 * (aopForSym): added an optimization to directly store in stack of
3404 the operand of a SEND iCode,
3405 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3406 but as registers instead (AOP_REG) using the fReturnIdx array,
3407 * (pic16_freeAsmop): remove the freed register from the
3408 _G.sregsAlloc field,
3409 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3410 a compare of 'WREG',
3411 * (pic16_popGetTempRegCond): changed function prototype, now
3412 function takes also a bitVector argument v which holds the current
3413 set of registers that are allocated for stack access by aopForSym,
3414 registers allocated in aopForSym for accessing stack symbols are not
3415 any more part of the functions usedRegs field,
3416 * (genCall): some times aopOp is called for a stack variable to be
3417 send, aopForSym might perform the push, if this is true make sure
3418 that genCall doesn't push the variable twice by testing _G.resDirect,
3419 * (genFunction): changed testing for unspecified interrupt number
3420 from 256 to INTNO_UNSPEC,
3421 * modified selection scheme of frame pointer generation. Previously
3422 if function did use local registers a frame pointer was generated,
3423 now a frame pointer is generated only if function has arguments
3424 (that need PLUSW2 register access), or has stack arguments, or the
3425 compiler is not instructed to omit the frame pointer,
3426 * (genEndFunction): before restoring local registers that were saved
3427 in the function preamble, also restore the registers that *might*
3428 have been allocated for stack access,
3429 * (genRet): removed some old comments,
3430 * (genCmp, the active (RN's) version): added a call to the
3431 pic16_genCmp_special function to perform the compare with a more
3432 robust and optimized way,
3433 * (genInline): a feature has been added in inline code generation,
3434 which allows a wildcard variable substitution when writing inline
3435 assembly. Code is incomplete and experimental therefore undocumented,
3436 * (genCast): changed order of aopOp for result and right to allow
3437 aopForSym to directly load the result if possible,
3438 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3439 perform an optimized compare on some selected special occasions,
3440 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3441 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3442 generate an IVT any more,
3443 * src/pic16/main.c (pic16_optionsTable): added command line option
3445 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3446 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3448 * src/pic16/NOTES: Raphael Neider added in list of active developers
3449 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3450 jumptable_end to prevent bug #,
3451 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3452 inCond and outCond fields,
3453 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3454 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3455 turn off register spilling,
3456 * (packRegsForOneUse): synced with other ports' versions although it
3457 is not used currently,
3458 * (pic16_packRegisters): added an optimization while reading
3459 structure bitfields, some registers may be saved (malloc code is
3460 decreased by 80 bytes)
3462 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3464 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3465 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3466 this can be optimized more?
3468 2005-03-10 Raphael Neider <rneider AT web.de>
3470 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3471 genNearPointerGet): (hopefully) fixed access to bitfields via
3472 pointers (p->bitN = x; and x = p->bitN; failed)

4106 Adding support for replacing ljmps with sjmps in jumptables
4107 generated for switch statements. For now you need to set the
4108 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4109 Now 4 algorithms for mcs51 jumptable generation are used:
4110 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4111 addresses loaded pc-relative for up to 112 cases and stack-pushing
4112 target addresses loaded with offset from dptr for up to 256 cases.

4142 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4144 * added libc directory. The current version of LibC contains string
4145 functions, ctype functions and macros and some functions of the
4146 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4147 be extensively tested in the future. Standard disclaimer here.
4148 Library is not automatically build yet. But one can build it by
4149 invoking 'make' inside the libc directory.

4160 * (pic16_storeForReturn): optimized return of 0,
4161 * (genCmp): experimental code for new genCmp which uses PIC18's
4162 special compare&skip instructions. Initial tests fail some times
4163 with variables grater than 1 byte in size, so new code is disabled,
4164 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4166 * (genCast): began a fix to optimize the casting of a bit to another
4167 bit, now assigning a bitfield to another bitfield will fail, sorry,

4176 and 1 for banking instruction,
4177 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4178 caused stop processing pCodes after a inline assembly block,
4179 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4181 registers when it shouldn't,
4182 * src/pic16/ralloc.c (allocReg): add preliminary support for
4183 supporting a limited set of temporary registers,
4185 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4191 (genFunction): optimize RECEIVE iCodes in reentrant functions
4193 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7193 loaded with the linker search paths (-L arguments) and the libraries
7194 to be linked with the current source (-l arguments). Changes
7195 currently will affect only the pic16 port.
7196 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7197 include path the port specific paths and port specific libraries,
7198 * gplink command now contains the $3 argument,
7199 * src/pic16/device.h,

7216 Documenting changes from previous commits.
7217 * configure.in (version 1.56),
7218 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7219 when generating output files to configure the pic16 library,
7220 but now I've commented it out, since gputils aren't installed in the
7221 SF compile farm, so library won't compile
7223 * device/lib/Makefile.in (version 1.56): initially I've added in
7224 target 'all' the prerequestive 'model-pic16' so it compiled the
7225 pic16 library, but now I've commented it out for the same reasons
7227 * added targets 'model-pic16' and 'objects-pic16' to compile the
7229 * added target 'port-specific-objects-pic16' to handle the
7230 generated libraries and copy them into the build/ directory
7231 * added target 'clean-intermediate-pic16' to clean intermediate
7232 files into pic16 directory
7233 * in target 'installdirs' added line to create directory pic16 in

7487 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7489 A python script to validate compiler diagnostic messages. It can be
7490 used to verify that sdcc complains about bad c source code and
7491 gives a good location of the error.
7492 * support/valdiag/Makefile,
7493 * support/valdiag/valdiag.py,
7494 * support/valdiag/tests/*
7496 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7498 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7499 * src/SDCCsymt.c (newEnumType),
7501 * support/Util/SDCCerr.c,
7502 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
7504 * support/regression/tests/enum.c: added test for enum values that
7505 require at least 2 bytes of storage.
7507 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7509 * src/common.h: added ifndef/define/endif macros
7510 around the header file.
7511 Bug reported from Jesus Calvino-Fraga
7513 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7515 * sdcc.spec: updated
7516 * device/include/Makefile.in: don't install CVS directories
7517 * device/lib/Makefile.in: added removal of CVS directories after install
7518 * doc/Makefile: fixed install, added local_icons
7519 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7520 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7521 * src/ds390/gen.c (genRightShift): fixed bug #870788
7522 * src/SDCCast.c (decorateType): fixed bug #870781
7524 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7526 PIC16 port related changes:
7527 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7528 added variable stackPos,
7530 * gen.c: genCall, assignResultValue: added support for
7531 pushing/retrieving function parameters to/from stack,
7532 genFunction,genEndFunction: setup stack frame for the
7534 genAddrOf: will be changed according to bug 863624
7536 * added files genutils.c and genutils.h which contain gen*
7537 debugged and optimised functions extracted from gen.c
7539 * glue.c: added variable 'externs' which holds extern symbols,
7540 pic16emitRegularMap: is modified to properly handle relocatable
7541 symbols under the new scheme,
7542 pic16createInterruptVect: is modified
7543 pic16printPublics: is modified to emit 'global' assembler directives,
7544 added pic16_printExterns to print extern symbols,
7545 pic16glue: initializes stack/frame pointer in the beginning of
7546 the assembly output. Temporary hack, will be corrected later,
7547 because gplink yet does not support stack and SDCC does not
7548 yet support a type of crt0.o object to create the final binary.
7550 * Removed many lines that contain 8051 legacy code.
7551 * The code is finally placed under a 'code' directive.
7552 * Added port specific options.
7554 * _process_pragma: simplified since now we do not need *special*
7555 include file to define SFR registers. But a separate header
7556 will be needed. This will be developed later.
7557 * _pic16_parseOptions: added, parses port specific options:
7558 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7559 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7560 --preplace-udata-with=
7562 * _pic16_setDefaultOptions: modified to initialize section names,
7563 but hack is temporarly out of order since it needs improvement.
7564 * _pic16_genAssemblerPreamble: configuration words are emitted by
7565 their address instead of their name. This part is incomplete and
7566 supports only the 18Fxx2 devices. Other devices will emit an error
7567 during assembly since they do not contain the same set of config
7569 * _pic16_genIVT: is modified,
7571 * pcode.c: added definitions for some hardware registers that are needed
7573 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7574 All PCI entries are updated. Now LFSR is supported.
7575 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7576 * added pic16_newpCodeOpLit2 to support instructions with
7577 two literal arguments
7578 * pic16_pCode2str: corrected code that emits assembler instructions
7579 with two literal operands and those that have an access bit modifier
7580 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7581 this fixes a bug which caused some labels to be lost, when an
7582 assembler directive was added, i.e. banksel,
7583 * pic16_FixRegisterBanking: improved logic that causes the insertion
7585 * InlineFunction: functions that are called once, are not any more
7586 inlined. This can be a port option in the future,
7588 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7590 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7591 hold the corresponding uninitialized symbols,
7592 * pic16_allocProcessorRegister: registers have explicit marked the
7594 * pic16_allocInternalRegister: registers are explicit marked as
7596 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7597 processing list, so bit registers were lost,
7600 * ralloc.h: added field 'accessBank' and original symbol operand
7601 in register definition,
7602 * removed the field isMapped from register definition,
7604 ** Several functions have been removed from various sources:
7605 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7606 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7607 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7608 pic16_assignRelocatableRegisters
7610 ** others have been introduced:
7611 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7612 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7614 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7616 * support/scripts/inc2h.pl: changed definition of BIT_AT
7617 to emit 'sbit at' instead of 'bit at'. This was a request.
7619 PIC16 port related preliminary changes:
7620 * gen.c: prefixed function popRegFromString with
7621 pic16_ and all references to it corrected
7622 * pcode.c: all pic16_pc_* hardware registers prefixed
7623 with underscore (_),
7624 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7625 * ralloc.c: newReg(): when register is REG_SFR then
7626 set address to rIdx,
7627 pic16_allocProcessorRegister(): marks register wasUsed=0
7628 pic16_writeUsedRegs(): added a call to assign processor
7629 registers via pic16_assignFixedRegisters
7631 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7633 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7634 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7635 variables in unused register banks. Also the SSEG is placed
7636 wherever there is enough space for it, and IDATA can be anywhere
7637 in internal RAM. For now compile using -Wl-Y[stack_size].
7638 The mem file is different for this option as well, since it
7639 makes no sense of talking about DSEG lenght.
7641 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7643 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7644 in certain cases, e.g. when ROM assignment, patch provided
7645 from Albert den Haan.
7647 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7790 * src/mcs51/peephole.def,
7791 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7886 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7888 * src/SDCCast.c (decorateType): disabled a transformation I added in
7889 revision 1.188 (access to fields of a structure at an absolute address);
7890 it breaks with bitfields, extern declarations, and gcse analysis.
7891 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7892 could be assigned through a pointer, so don't complain.
7893 * src/SDCCast.c (astErrors),
7895 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8532 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8533 support for standard C idiom of memory mapped variables; for
8534 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8535 to xdata int at 0x1234 tempvar = 1.
8536 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8537 provided by Akiya ISHIDA

8553 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8555 Fixed bug #621531 (const & volatile confusion in the type chain).
8556 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8557 refer to the const or volatile state of the pointer itself.

8648 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8649 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8650 fetching of the pointer
8651 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8652 copied from genNearPointerSet()
8653 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8654 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8655 If they pop r0/r1 they must be called in the opposite order than aopOp().
8656 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8657 (resp. --stack-auto), prepared for --xstack

8668 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8670 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8671 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8672 type for bits was changed. It resulted in bit variables becoming
8673 global, which is not permitted in PIC 14 assembly output.
8675 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8677 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8690 A few small changes that speed up the peephole optimizer.
8694 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8696 Try to make the peephole optimizer smarter by maintaining
8697 an association between the assembly source code and the
8698 iCodes that originated them. Put this information to use
8699 with a new peephole rule condition "notVolatile" so that
8700 the rules can be aggressive yet still safe.
8705 * src/mcs51/peeph.def
8707 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8711 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8712 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8713 if the left or right operand symbols have the accuse flag set.
8715 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8717 Changed the type of the result of the ! (NOT) operator to char;
8718 previously it returned the same type as the source. This allows
8719 us to eliminate all the genFloatNot functions (all of its target
8720 implementations were very buggy) since !float can use the same
8723 * src/SDCCicode.c (ast2iCode): ! returns char

8732 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8733 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8734 during interrupts. Ensure WSAVE is located at a shared bank address.
8735 2. Fixed page selection in some places
8736 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8737 the registers name strings.
8738 4. Fixed "signed / unsigned compare" compiler warnings.
8739 5. The PIC port manages its own allocation of the general purpose
8740 registers, but makes no attempt to reuse them. As a result when
8741 compiling it soon runs out of general purpose registers. Some
8742 additional code was added to the files pcode.c and device.c to walk
8743 through the function call tree and rename the registers so that they
8753 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8754 genPlus() & genMinus() when the result is the same as left or right

8760 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8762 Made bitfield a distinct type from bit so that bitfields
8763 convert as per ANSI C and bits retain their traditional
8764 boolean style behaviour. Implemented bitfield support in
8772 * src/ds390/gen.c: bit v bitfield split
8773 * src/z80/gen.c: New support for bitfields
8774 * support/regression/tests/bitfields.c: reenabled z80,
8777 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8779 Rules 246.x, 247.x relate to bitfields, the others speed up
8780 access to xdata mapped I/O devices.
8782 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8784 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8786 Cleaned up genPackBits and genUnpackBits and added two helper
8787 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8788 for literal assignments in genPackBits (thanks to Frieder for
8794 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8796 Fixed bug #748310 (pointer to function type mishandled when the
8797 function name is omitted). Also fixed a SIGSEGV when a function
8798 attribute (reentrant, etc) is used on a non-function or on a
8799 function but misplaced before the parameter list.
8801 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8803 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8804 * support/Util/SDCCerr.h,
8805 * support/Util/SDCCerr.c: Added func attr misuse error msg

8826 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8828 Made the constant following the "interrupt" keyword optional. If
8829 omitted, the function will not automatically be given an entry
8830 in the interrupt vector table (similar to #pragma NOIV, but
8831 less syntacticly kludgy). The interrupt number is also now
8832 range checked. Also fixed a bug in the high order bit example

8846 * src/SDCCicode.c (operandOperation): rewritten some ops
8847 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8848 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8850 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8851 be re-activated by defining REDUCE_LITERALS)
8852 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8853 unsigned, but are signed by default
8854 * src/SDCCval.c (constVal): rearranged
8855 * src/SDCCval.c (valMod): preliminary fix
8856 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9362 added if/endif conditional macros to remove options help
9363 messages from optionsTable when a port is not configured, added
9364 support for the PIc16 port in the ports table, when executing
9365 the compiler with no port specified on command line, a default
9366 port is selected with the new macro DEFAULT_PORT which is
9367 defined in port.h, in setDefaultOptions() linkOptions is removed
9368 from initialization assignment, since now it is a set,
9369 parseCmdLine uses setParseWithComma for linkOptions, in
9370 linkEdit() linkOptions are accessed with new function indexSet()
9371 which returns the i'th item of a set variable. See SDCCset.c, in
9372 linkEdit() when calling buildCmdLine(), added linkOptions as
9373 last argument. Now users can pass arguments to gplink via the
9374 -Wl option, main() uses pic16glue() to glue up pic16 programs

9388 gpasm complaining and test the linkage with gplink, _linkCmd and
9389 _asmCmd changed to be more gplink and gpasm friendly
9390 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9391 produced an error when parsed, peep rule 12 is added to utilize
9392 movff, but it is commented out since the pCode does not support
9393 yet a command with 2 address arguments
9395 2003-05-18 <johan AT balder>
9397 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9424 2003-05-11 Borut Razem <borut.razem AT siol.net>
9426 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10432 * src/SDCCicode.c: fixed array add
10434 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10435 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10436 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10438 2003-01-04 <johan AT balder>
10440 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10442 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10443 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10445 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10446 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10447 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10449 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10450 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10452 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10453 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10455 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10456 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10458 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10460 * in \sdcc\as\mcs51\ changed these files in order to create an
10461 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10462 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10463 following files to include the previous two files: aslink.dsp,
10464 Makefile.aslink, Makefile.bcc, and Makefile.in.
10466 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10467 .adb instead of .cdb
10469 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10471 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10472 value from option --iram-size.
10474 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10476 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10479 2002-09-18 <wiml AT hhhh.org>
10481 * SDCClrange.h: exposed setFromRange() and setToRange()
10482 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10483 packRegsForAccUse() (bug 542397)
10484 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10485 multiple times and emitting the fetch operations more than once
10486 added aopGetUsesAcc() function to allow binary operators to
10487 fetch their operands in the correct order; made genMinus() emit
10488 compact code for X = LITERAL - Y
10490 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10491 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10492 sprintf() in line 1267.
10494 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10495 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10498 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10499 Changes to aslink (All the changes are marked with 'JCF'):
10501 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10504 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10505 area BSEG. Also moves, if possible, the DATA area down into the internal
10506 ram so more space is available.
10508 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10511 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10512 not bytes. Function summary() which creates a memory usage summary
10513 file with extension .mem. Reports of overlaping stack and small stack
10514 size. If the space for the stack is less than 16 bytes aslink trows a
10517 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10518 the 8051. Option 'y' for memory summary output file.
10520 Changes to sdcc (All the changes are marked with 'JCF'):
10522 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10524 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10525 overlaying area for it (uses RegBankUsed[4]).
10527 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10528 bank zero as used by default. By default aslink locates the stack
10529 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10530 the creation of the .mem file. Delegates the allocation of data area
10531 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10532 the begining of the stack area to aslink.
10534 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10535 glue() in SDCCglue.c creates an area for it.
10537 2002-09-03 Borut Razem <borut.razem AT siol.net>
10538 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10539 sdcc/src/pic/glue.c:
10540 introduced atexit() handler for teporay files removal in case of
10541 errors, assertions, ...
10543 2002-08-29 Borut Razem <borut.razem AT siol.net>
10544 * sdcc/support/cpp2/auto-host_vc_in.h:
10545 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10546 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10547 Maybe there is a similar problem with BORLANDC? It should be checked!
10549 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10550 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10551 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10552 was not executed, and the compiler (cl) launched a warning:
10553 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10555 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10556 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10558 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10559 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10561 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10562 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10563 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10564 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10565 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10566 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10567 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10568 - added Release configuration in VS projects
10569 - review of compiler an linker options
10570 - VC .exe files are generated in bin_vc directory, not to interfere
10571 with binaries generated from other projects (cygwin, mingw, bcc ...)
10573 * sdcc/src/yacc.dsp: added
10575 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10576 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10577 and insert the version number definitions from .version
10579 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10581 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10582 added - genarate auto-host.h using auto-host_vc_in.h as template
10585 removed from CVS, generated automatically
10587 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10588 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10590 2002-08-11 Borut Razem <borut.razem AT siol.net>
10591 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10593 2002-08-10 Borut Razem <borut.razem AT siol.net>
10594 * src/SDCCmain.c (main):
10595 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10596 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10597 The consequence was that some temporary files were not removed.
10600 unification of code in functions tempfilename() and tempfile():
10601 function tempnam() is defined in Visual Studio 6.0 and .NET
10603 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10605 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10606 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10607 - removed compiler command line option /WX: Treats all warnings as errors
10608 - update a list of source files, included into the project
10610 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10611 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10612 changed project type to Generic Project so that can be correcly converted to VS.NET project
10614 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10616 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10618 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10620 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10621 added return 0 statements after assert() to make compiler happy
10623 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10624 added newline in the def file to keep MSC compiler satisfied
10626 * sdcc/src/z80/gen.c:
10627 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10628 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10629 - solved MSC error in function aopDump()
10631 * sdcc_vc.h: define PREFIX as "\\sdcc"
10633 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10634 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10640 singly-used registers optimized away)
10642 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10644 * 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.

10667 * src/z80/main.c: Added force callee saves for jaune.
10669 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10671 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10673 2002-03-28 Johan Knol <johan AT balder>
10675 * src/SDCCval.c: fixed bug #532436
10677 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10679 Added "char *Processor" field to the port structure.
10682 Added -p option. Allows port dependent processor to be specified.
10685 Initialized the new field char *Processor field to NULL in all ports
10688 Compiler generated registers for interrupt context saving
10689 were not getting allocated.
10691 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10694 Fixed left shift. Will promote the left side of a left shift
10695 if a) left shifting more than size of operand or b) when assigned
10696 to something size > size of left side
10698 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10700 tons of changes. Register allocation has been
10701 rewritten. Added customization for the various PICs. Flow
10702 analysis is restructured. ...
10704 * src/pic/device.h:
10707 * src/pic/device.c:
10708 Added. device.c is a PIC port hack to accomodate variations
10711 2002-03-13 Michael Hope <michaelh AT vroom>
10713 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10715 2002-03-04 johanknol <johanknol AT manik>
10717 * /src/SDCCval.c: fixed
10719 const unsigned char arr[][2] = { { 0, 1 } };

10806 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10808 * sdcc/src/SDCCloop.c:
10809 Previous fix was not good. basic blocks that have "break" or "return" are
10810 not really partof a loop , but live ranges used in these blocks should
10811 be live thru the entire loop, so set partOfLoop but don't add them to
10814 2002-02-21 <johan AT FRIJA>
10816 * src/SDCCcse.c: fixed bug #514308
10818 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10821 Fixed BUG #519583. If a conditional block ended in a return/break
10822 statement inside a loop, it was not being considered part of the loop.
10824 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10826 2002-02-10 Karl Bongers <karl AT turbobit.com>

10840 Took out debug printfs in ucsim "next" command.
10842 * sim/ucsim/xa.src:
10843 Karl and Johan start ucsim XA support. Most dissassembly working,
10844 about 75% emulation done(plenty of work remaining).
10846 * sim/ucsim/z80.src:
10847 Add Z80 support to ucsim, add test-ucz80 regression test,
10848 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10849 Notice z80 compiler fails on examples/test3.c/crc code.
10851 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10853 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
