562 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
564 Enabled VPATH feature: changed nearly all Makefiles (149 files).
565 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
567 One basic decision: e.g. src/clean.mk includes further files. In order
568 to make this work there are two solutions:
569 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
570 run configure on them. This way they can use
571 'include $(srcdir)/port-clean.mk'
572 - always include clean.mk by the Makefile at the same level. To avoid
573 that `make clean` tries to include and build Makefile.dep the
574 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
575 implemented, because now even `make uninstall` doesn't create
576 Makefile.in. clean.mk could be eliminated by pasting it in
579 * debugger/mcs51/Makefile.in: build own objects from library sources
580 (SLIB, SDCC) in current directory
582 * configure, configure.in: renamed --disable-device-lib-build in
583 --disable-device-lib; added --enable-doc, the required tools are
584 searched by configure; added result message; the toolchain for the
585 belonging ports are now only built, if the port is enabled.
587 * support/regression/*: all output is written in directory gen, because
588 the fwk and ports directories don't livet in the build tree using vpath
590 * doc/sdccman.lyx: renamed --disable-device-lib-build to
591 --disable-device-lib, added --enable-doc, added section VPATH
593 * sim/ucsim/configure.in,
594 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
595 z80 are enabled by default
597 2006-04-24 Raphael Neider <rneider AT web.de>
599 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
600 to config word, "pic14_"-prefixed some extern functions

602 config word has been found
603 * src/pic/device.h: added prototypes

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

965 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
966 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
968 2006-03-06 Borut Razem <borut.razem AT siol.net>
970 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
971 made the linker quiet
973 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
975 * src/pic16/gen.c (genPcall): fixed bug #1443644
976 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
977 which dumps before the function entry point a data byte which represents
978 the number of the local variables used by the specified function, added
979 'xinst' for initial support for Extended Instruction Support,
980 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
981 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
982 port->fun_prefix anymore (may change later),
983 (genFunction, genEndFunction): do not store/restore local registers for
984 _main (this should take care the --main-return command line option in
986 (genOr): removed some legacy pic-port instructions,
987 * src/pic16/genarith.c (genAddLit): re-enabled old code because
988 performing operations with SFR's causes data to be written more than
989 once to each SFR. Perhaps SFRs should be handled in special cases...
990 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
992 * src/pic16/main.c (_process_pragma): stack bound checking did not take

995 --extended or -y for Extended Instruction Support,
996 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
997 (deassignLRs): *** perhaps the most important change, old 'for' code
998 (commented out for reference), didn't account for some registers which
999 were left marked 'not free' after a pointer operation. The change
1000 reduces register usage a lot in some cases

3275 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3276 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3277 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3278 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3279 always available in leading double underscore form. The C99 support is

3360 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3362 * device/lib/printf_large.c: removed inline assembly for portability and
3363 readability. Use printf_fast if speed or size are more important.
3364 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3365 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3367 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3369 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3370 prevent compiler warning
3372 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3374 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3375 moved to level 0 and declared as static. Also they are explicit
3376 placed in access bank. This was necessery because some times they
3377 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3378 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3379 optimizations. Currently only compare to unsigned char is implemented,
3380 * src/pic16/gen.c: added fReturnIdx array,
3381 * (struct resolvedIfx) is moved to gen.h and made public,
3382 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3383 * (aopForSym): added an optimization to directly store in stack of
3384 the operand of a SEND iCode,
3385 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3386 but as registers instead (AOP_REG) using the fReturnIdx array,
3387 * (pic16_freeAsmop): remove the freed register from the
3388 _G.sregsAlloc field,
3389 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3390 a compare of 'WREG',
3391 * (pic16_popGetTempRegCond): changed function prototype, now
3392 function takes also a bitVector argument v which holds the current
3393 set of registers that are allocated for stack access by aopForSym,
3394 registers allocated in aopForSym for accessing stack symbols are not
3395 any more part of the functions usedRegs field,
3396 * (genCall): some times aopOp is called for a stack variable to be
3397 send, aopForSym might perform the push, if this is true make sure
3398 that genCall doesn't push the variable twice by testing _G.resDirect,
3399 * (genFunction): changed testing for unspecified interrupt number
3400 from 256 to INTNO_UNSPEC,
3401 * modified selection scheme of frame pointer generation. Previously
3402 if function did use local registers a frame pointer was generated,
3403 now a frame pointer is generated only if function has arguments
3404 (that need PLUSW2 register access), or has stack arguments, or the
3405 compiler is not instructed to omit the frame pointer,
3406 * (genEndFunction): before restoring local registers that were saved
3407 in the function preamble, also restore the registers that *might*
3408 have been allocated for stack access,
3409 * (genRet): removed some old comments,
3410 * (genCmp, the active (RN's) version): added a call to the
3411 pic16_genCmp_special function to perform the compare with a more
3412 robust and optimized way,
3413 * (genInline): a feature has been added in inline code generation,
3414 which allows a wildcard variable substitution when writing inline
3415 assembly. Code is incomplete and experimental therefore undocumented,
3416 * (genCast): changed order of aopOp for result and right to allow
3417 aopForSym to directly load the result if possible,
3418 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3419 perform an optimized compare on some selected special occasions,
3420 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3421 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3422 generate an IVT any more,
3423 * src/pic16/main.c (pic16_optionsTable): added command line option
3425 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3426 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3428 * src/pic16/NOTES: Raphael Neider added in list of active developers
3429 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3430 jumptable_end to prevent bug #,
3431 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3432 inCond and outCond fields,
3433 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3434 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3435 turn off register spilling,
3436 * (packRegsForOneUse): synced with other ports' versions although it
3437 is not used currently,
3438 * (pic16_packRegisters): added an optimization while reading
3439 structure bitfields, some registers may be saved (malloc code is
3440 decreased by 80 bytes)
3442 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3444 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3445 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3446 this can be optimized more?
3448 2005-03-10 Raphael Neider <rneider AT web.de>
3450 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3451 genNearPointerGet): (hopefully) fixed access to bitfields via
3452 pointers (p->bitN = x; and x = p->bitN; failed)
3454 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3456 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3468 * support/regression/tests/critical.c: check bug 1144613
3470 2005-03-02 Raphael Neider <rneider AT web.de>
3472 * src/pic16/gen.c (genRightShiftLiteral): fixed bug #1154256
3474 2005-02-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4086 Adding support for replacing ljmps with sjmps in jumptables
4087 generated for switch statements. For now you need to set the
4088 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4089 Now 4 algorithms for mcs51 jumptable generation are used:
4090 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4091 addresses loaded pc-relative for up to 112 cases and stack-pushing
4092 target addresses loaded with offset from dptr for up to 256 cases.

4122 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4124 * added libc directory. The current version of LibC contains string
4125 functions, ctype functions and macros and some functions of the
4126 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4127 be extensively tested in the future. Standard disclaimer here.
4128 Library is not automatically build yet. But one can build it by
4129 invoking 'make' inside the libc directory.

4140 * (pic16_storeForReturn): optimized return of 0,
4141 * (genCmp): experimental code for new genCmp which uses PIC18's
4142 special compare&skip instructions. Initial tests fail some times
4143 with variables grater than 1 byte in size, so new code is disabled,
4144 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4146 * (genCast): began a fix to optimize the casting of a bit to another
4147 bit, now assigning a bitfield to another bitfield will fail, sorry,
4148 * src/pic16/main.c: disabled the use of lr-support feature,
4149 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4156 and 1 for banking instruction,
4157 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4158 caused stop processing pCodes after a inline assembly block,
4159 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4160 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4161 registers when it shouldn't,
4162 * src/pic16/ralloc.c (allocReg): add preliminary support for
4163 supporting a limited set of temporary registers,
4165 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4167 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4168 genDataPointerSet): ensure assignments always copy in MSB to LSB
4170 (loadRegFromAop): recognize CLRH optimization,
4171 (genFunction): optimize RECEIVE iCodes in reentrant functions
4173 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4175 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7173 loaded with the linker search paths (-L arguments) and the libraries
7174 to be linked with the current source (-l arguments). Changes
7175 currently will affect only the pic16 port.
7176 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7177 include path the port specific paths and port specific libraries,
7178 * gplink command now contains the $3 argument,

7196 Documenting changes from previous commits.
7197 * configure.in (version 1.56),
7198 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7199 when generating output files to configure the pic16 library,
7200 but now I've commented it out, since gputils aren't installed in the
7201 SF compile farm, so library won't compile
7203 * device/lib/Makefile.in (version 1.56): initially I've added in
7204 target 'all' the prerequestive 'model-pic16' so it compiled the
7205 pic16 library, but now I've commented it out for the same reasons
7207 * added targets 'model-pic16' and 'objects-pic16' to compile the
7209 * added target 'port-specific-objects-pic16' to handle the
7210 generated libraries and copy them into the build/ directory
7211 * added target 'clean-intermediate-pic16' to clean intermediate
7212 files into pic16 directory
7213 * in target 'installdirs' added line to create directory pic16 in

7491 Bug reported from Jesus Calvino-Fraga
7493 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7495 * sdcc.spec: updated
7496 * device/include/Makefile.in: don't install CVS directories
7497 * device/lib/Makefile.in: added removal of CVS directories after install
7498 * doc/Makefile: fixed install, added local_icons
7499 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7500 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7501 * src/ds390/gen.c (genRightShift): fixed bug #870788
7502 * src/SDCCast.c (decorateType): fixed bug #870781
7504 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7506 PIC16 port related changes:
7507 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7508 added variable stackPos,
7510 * gen.c: genCall, assignResultValue: added support for
7511 pushing/retrieving function parameters to/from stack,
7512 genFunction,genEndFunction: setup stack frame for the
7514 genAddrOf: will be changed according to bug 863624
7516 * added files genutils.c and genutils.h which contain gen*
7517 debugged and optimised functions extracted from gen.c
7519 * glue.c: added variable 'externs' which holds extern symbols,
7520 pic16emitRegularMap: is modified to properly handle relocatable
7521 symbols under the new scheme,
7522 pic16createInterruptVect: is modified
7523 pic16printPublics: is modified to emit 'global' assembler directives,
7524 added pic16_printExterns to print extern symbols,
7525 pic16glue: initializes stack/frame pointer in the beginning of
7526 the assembly output. Temporary hack, will be corrected later,
7527 because gplink yet does not support stack and SDCC does not
7528 yet support a type of crt0.o object to create the final binary.
7530 * Removed many lines that contain 8051 legacy code.
7531 * The code is finally placed under a 'code' directive.
7532 * Added port specific options.
7534 * _process_pragma: simplified since now we do not need *special*
7535 include file to define SFR registers. But a separate header
7536 will be needed. This will be developed later.
7537 * _pic16_parseOptions: added, parses port specific options:
7538 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7539 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7540 --preplace-udata-with=
7542 * _pic16_setDefaultOptions: modified to initialize section names,
7543 but hack is temporarly out of order since it needs improvement.
7544 * _pic16_genAssemblerPreamble: configuration words are emitted by
7545 their address instead of their name. This part is incomplete and
7546 supports only the 18Fxx2 devices. Other devices will emit an error
7547 during assembly since they do not contain the same set of config
7549 * _pic16_genIVT: is modified,
7551 * pcode.c: added definitions for some hardware registers that are needed
7553 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7554 All PCI entries are updated. Now LFSR is supported.
7555 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7556 * added pic16_newpCodeOpLit2 to support instructions with
7557 two literal arguments
7558 * pic16_pCode2str: corrected code that emits assembler instructions
7559 with two literal operands and those that have an access bit modifier
7560 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7561 this fixes a bug which caused some labels to be lost, when an
7562 assembler directive was added, i.e. banksel,
7563 * pic16_FixRegisterBanking: improved logic that causes the insertion
7565 * InlineFunction: functions that are called once, are not any more
7566 inlined. This can be a port option in the future,
7568 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7570 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7571 hold the corresponding uninitialized symbols,
7572 * pic16_allocProcessorRegister: registers have explicit marked the
7574 * pic16_allocInternalRegister: registers are explicit marked as
7576 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7577 processing list, so bit registers were lost,
7580 * ralloc.h: added field 'accessBank' and original symbol operand
7581 in register definition,
7582 * removed the field isMapped from register definition,
7584 ** Several functions have been removed from various sources:
7585 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7586 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7587 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7588 pic16_assignRelocatableRegisters
7590 ** others have been introduced:
7591 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7592 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7594 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7596 * support/scripts/inc2h.pl: changed definition of BIT_AT
7597 to emit 'sbit at' instead of 'bit at'. This was a request.
7599 PIC16 port related preliminary changes:
7600 * gen.c: prefixed function popRegFromString with
7601 pic16_ and all references to it corrected
7602 * pcode.c: all pic16_pc_* hardware registers prefixed
7603 with underscore (_),
7604 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7605 * ralloc.c: newReg(): when register is REG_SFR then
7606 set address to rIdx,
7607 pic16_allocProcessorRegister(): marks register wasUsed=0
7608 pic16_writeUsedRegs(): added a call to assign processor
7609 registers via pic16_assignFixedRegisters
7611 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7613 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7614 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7615 variables in unused register banks. Also the SSEG is placed
7616 wherever there is enough space for it, and IDATA can be anywhere
7617 in internal RAM. For now compile using -Wl-Y[stack_size].
7618 The mem file is different for this option as well, since it
7619 makes no sense of talking about DSEG lenght.
7621 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7623 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7624 in certain cases, e.g. when ROM assignment, patch provided
7625 from Albert den Haan.
7627 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7783 multiply defined with mismatching "at" address.
7785 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7787 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

7866 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7868 * src/SDCCast.c (decorateType): disabled a transformation I added in
7869 revision 1.188 (access to fields of a structure at an absolute address);
7870 it breaks with bitfields, extern declarations, and gcse analysis.
7871 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7872 could be assigned through a pointer, so don't complain.
7873 * src/SDCCast.c (astErrors),
7875 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8513 support for standard C idiom of memory mapped variables; for
8514 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8515 to xdata int at 0x1234 tempvar = 1.
8516 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8517 provided by Akiya ISHIDA

8533 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8535 Fixed bug #621531 (const & volatile confusion in the type chain).
8536 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8537 refer to the const or volatile state of the pointer itself.

8602 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8603 pcoderegs.h, ralloc.c, ralloc.h
8604 * main.c: added top header and GPL license notice

8628 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8629 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8630 fetching of the pointer
8631 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8632 copied from genNearPointerSet()
8633 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8634 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8635 If they pop r0/r1 they must be called in the opposite order than aopOp().
8636 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8637 (resp. --stack-auto), prepared for --xstack

8648 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8650 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8651 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8652 type for bits was changed. It resulted in bit variables becoming
8653 global, which is not permitted in PIC 14 assembly output.
8655 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8657 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8659 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8661 Z80 and MCS51 linkers complaint if a public symbol is defined

8670 A few small changes that speed up the peephole optimizer.
8674 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8676 Try to make the peephole optimizer smarter by maintaining
8677 an association between the assembly source code and the
8678 iCodes that originated them. Put this information to use
8679 with a new peephole rule condition "notVolatile" so that
8680 the rules can be aggressive yet still safe.
8685 * src/mcs51/peeph.def
8687 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8691 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8692 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8693 if the left or right operand symbols have the accuse flag set.
8695 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8697 Changed the type of the result of the ! (NOT) operator to char;
8698 previously it returned the same type as the source. This allows
8699 us to eliminate all the genFloatNot functions (all of its target
8700 implementations were very buggy) since !float can use the same
8703 * src/SDCCicode.c (ast2iCode): ! returns char

8712 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8713 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8714 during interrupts. Ensure WSAVE is located at a shared bank address.
8715 2. Fixed page selection in some places
8716 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8717 the registers name strings.
8718 4. Fixed "signed / unsigned compare" compiler warnings.
8719 5. The PIC port manages its own allocation of the general purpose
8720 registers, but makes no attempt to reuse them. As a result when
8721 compiling it soon runs out of general purpose registers. Some
8722 additional code was added to the files pcode.c and device.c to walk
8723 through the function call tree and rename the registers so that they
8733 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8734 genPlus() & genMinus() when the result is the same as left or right

8740 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8742 Made bitfield a distinct type from bit so that bitfields
8743 convert as per ANSI C and bits retain their traditional
8744 boolean style behaviour. Implemented bitfield support in
8752 * src/ds390/gen.c: bit v bitfield split
8753 * src/z80/gen.c: New support for bitfields
8754 * support/regression/tests/bitfields.c: reenabled z80,
8757 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8759 Rules 246.x, 247.x relate to bitfields, the others speed up
8760 access to xdata mapped I/O devices.
8762 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8764 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8766 Cleaned up genPackBits and genUnpackBits and added two helper
8767 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8768 for literal assignments in genPackBits (thanks to Frieder for
8774 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8776 Fixed bug #748310 (pointer to function type mishandled when the
8777 function name is omitted). Also fixed a SIGSEGV when a function
8778 attribute (reentrant, etc) is used on a non-function or on a
8779 function but misplaced before the parameter list.
8781 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8783 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8784 * support/Util/SDCCerr.h,
8785 * support/Util/SDCCerr.c: Added func attr misuse error msg

8806 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8808 Made the constant following the "interrupt" keyword optional. If
8809 omitted, the function will not automatically be given an entry
8810 in the interrupt vector table (similar to #pragma NOIV, but
8811 less syntacticly kludgy). The interrupt number is also now
8812 range checked. Also fixed a bug in the high order bit example

8823 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8825 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8826 * src/SDCCicode.c (operandOperation): rewritten some ops
8827 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8828 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8830 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8831 be re-activated by defining REDUCE_LITERALS)
8832 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8833 unsigned, but are signed by default
8834 * src/SDCCval.c (constVal): rearranged
8835 * src/SDCCval.c (valMod): preliminary fix
8836 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8878 constants are unsigned; added recognition of "u" flag for unsigned
8879 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8880 * src/SDCCval.c (valDiv, valMod): fixed signdness
8881 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8882 signedness of modulo, left and right shift

9342 added if/endif conditional macros to remove options help
9343 messages from optionsTable when a port is not configured, added
9344 support for the PIc16 port in the ports table, when executing
9345 the compiler with no port specified on command line, a default
9346 port is selected with the new macro DEFAULT_PORT which is
9347 defined in port.h, in setDefaultOptions() linkOptions is removed
9348 from initialization assignment, since now it is a set,
9349 parseCmdLine uses setParseWithComma for linkOptions, in
9350 linkEdit() linkOptions are accessed with new function indexSet()
9351 which returns the i'th item of a set variable. See SDCCset.c, in
9352 linkEdit() when calling buildCmdLine(), added linkOptions as
9353 last argument. Now users can pass arguments to gplink via the
9354 -Wl option, main() uses pic16glue() to glue up pic16 programs

9368 gpasm complaining and test the linkage with gplink, _linkCmd and
9369 _asmCmd changed to be more gplink and gpasm friendly
9370 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9371 produced an error when parsed, peep rule 12 is added to utilize
9372 movff, but it is commented out since the pCode does not support
9373 yet a command with 2 address arguments
9375 2003-05-18 <johan AT balder>
9377 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9404 2003-05-11 Borut Razem <borut.razem AT siol.net>
9406 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10401 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10402 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10403 * src/pic/pcode.c: outcommented unused variable to remove warnings
10404 * src/pic/ralloc.c: outcommented unused variable to remove warnings
10406 2003-01-06 <karl AT turbobit.com>
10407 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
10410 2003-01-06 <johan AT balder>
10412 * src/SDCCicode.c: fixed array add
10414 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10415 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10416 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10418 2003-01-04 <johan AT balder>
10420 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10422 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10423 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10425 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10426 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10427 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10429 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10430 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10432 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10433 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10435 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10436 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10438 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10440 * in \sdcc\as\mcs51\ changed these files in order to create an
10441 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10442 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10443 following files to include the previous two files: aslink.dsp,
10444 Makefile.aslink, Makefile.bcc, and Makefile.in.
10446 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10447 .adb instead of .cdb
10449 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10451 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10452 value from option --iram-size.
10454 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10456 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10459 2002-09-18 <wiml AT hhhh.org>
10461 * SDCClrange.h: exposed setFromRange() and setToRange()
10462 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10463 packRegsForAccUse() (bug 542397)
10464 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10465 multiple times and emitting the fetch operations more than once
10466 added aopGetUsesAcc() function to allow binary operators to
10467 fetch their operands in the correct order; made genMinus() emit
10468 compact code for X = LITERAL - Y
10470 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10471 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10472 sprintf() in line 1267.
10474 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10475 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10478 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10479 Changes to aslink (All the changes are marked with 'JCF'):
10481 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10484 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10485 area BSEG. Also moves, if possible, the DATA area down into the internal
10486 ram so more space is available.
10488 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10491 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10492 not bytes. Function summary() which creates a memory usage summary
10493 file with extension .mem. Reports of overlaping stack and small stack
10494 size. If the space for the stack is less than 16 bytes aslink trows a
10497 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10498 the 8051. Option 'y' for memory summary output file.
10500 Changes to sdcc (All the changes are marked with 'JCF'):
10502 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10504 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10505 overlaying area for it (uses RegBankUsed[4]).
10507 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10508 bank zero as used by default. By default aslink locates the stack
10509 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10510 the creation of the .mem file. Delegates the allocation of data area
10511 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10512 the begining of the stack area to aslink.
10514 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10515 glue() in SDCCglue.c creates an area for it.
10517 2002-09-03 Borut Razem <borut.razem AT siol.net>
10518 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10519 sdcc/src/pic/glue.c:
10520 introduced atexit() handler for teporay files removal in case of
10521 errors, assertions, ...
10523 2002-08-29 Borut Razem <borut.razem AT siol.net>
10524 * sdcc/support/cpp2/auto-host_vc_in.h:
10525 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10526 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10527 Maybe there is a similar problem with BORLANDC? It should be checked!
10529 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10530 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10531 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10532 was not executed, and the compiler (cl) launched a warning:
10533 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10535 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10536 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10538 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10539 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10541 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10542 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10543 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10544 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10545 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10546 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10547 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10548 - added Release configuration in VS projects
10549 - review of compiler an linker options
10550 - VC .exe files are generated in bin_vc directory, not to interfere
10551 with binaries generated from other projects (cygwin, mingw, bcc ...)
10553 * sdcc/src/yacc.dsp: added
10555 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10556 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10557 and insert the version number definitions from .version
10559 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10561 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10562 added - genarate auto-host.h using auto-host_vc_in.h as template
10565 removed from CVS, generated automatically
10567 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10568 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10570 2002-08-11 Borut Razem <borut.razem AT siol.net>
10571 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10573 2002-08-10 Borut Razem <borut.razem AT siol.net>
10574 * src/SDCCmain.c (main):
10575 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10576 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10577 The consequence was that some temporary files were not removed.
10580 unification of code in functions tempfilename() and tempfile():
10581 function tempnam() is defined in Visual Studio 6.0 and .NET
10583 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10585 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10586 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10587 - removed compiler command line option /WX: Treats all warnings as errors
10588 - update a list of source files, included into the project
10590 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10591 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10592 changed project type to Generic Project so that can be correcly converted to VS.NET project
10594 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10596 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10598 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10600 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10601 added return 0 statements after assert() to make compiler happy
10603 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10604 added newline in the def file to keep MSC compiler satisfied
10606 * sdcc/src/z80/gen.c:
10607 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10608 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10609 - solved MSC error in function aopDump()
10611 * sdcc_vc.h: define PREFIX as "\\sdcc"
10613 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10614 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10617 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10618 - Rewrote the register banking algorithm.
10619 - Added pCode live-range analysis to registers (for now, only non-used and
10620 singly-used registers optimized away)
10622 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10624 * 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.

10649 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10651 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10653 2002-03-28 Johan Knol <johan AT balder>
10655 * src/SDCCval.c: fixed bug #532436
10657 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10659 Added "char *Processor" field to the port structure.
10662 Added -p option. Allows port dependent processor to be specified.
10665 Initialized the new field char *Processor field to NULL in all ports
10668 Compiler generated registers for interrupt context saving
10669 were not getting allocated.
10671 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10674 Fixed left shift. Will promote the left side of a left shift
10675 if a) left shifting more than size of operand or b) when assigned
10676 to something size > size of left side
10678 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10680 tons of changes. Register allocation has been
10681 rewritten. Added customization for the various PICs. Flow
10682 analysis is restructured. ...
10684 * src/pic/device.h:
10687 * src/pic/device.c:
10688 Added. device.c is a PIC port hack to accomodate variations
10691 2002-03-13 Michael Hope <michaelh AT vroom>
10693 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10695 2002-03-04 johanknol <johanknol AT manik>
10697 * /src/SDCCval.c: fixed
10699 const unsigned char arr[][2] = { { 0, 1 } };

10786 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10788 * sdcc/src/SDCCloop.c:
10789 Previous fix was not good. basic blocks that have "break" or "return" are
10790 not really partof a loop , but live ranges used in these blocks should
10791 be live thru the entire loop, so set partOfLoop but don't add them to
10794 2002-02-21 <johan AT FRIJA>
10796 * src/SDCCcse.c: fixed bug #514308
10798 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10801 Fixed BUG #519583. If a conditional block ended in a return/break
10802 statement inside a loop, it was not being considered part of the loop.
10804 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10806 2002-02-10 Karl Bongers <karl AT turbobit.com>

10812 * device/examples/test2.c:
10813 Fix bug, "red" variable not being initialized(compiler complained).
10815 * device/examples/Makefile, examples/test3.c:
10816 Add Makefile in device/examples folder, compiles test3.c
10817 for use as a multiple module SDCDB test case.
10819 * sim/ucsim/cmd.src/cmdset.cc:
10820 Took out debug printfs in ucsim "next" command.
10822 * sim/ucsim/xa.src:
10823 Karl and Johan start ucsim XA support. Most dissassembly working,
10824 about 75% emulation done(plenty of work remaining).
10826 * sim/ucsim/z80.src:
10827 Add Z80 support to ucsim, add test-ucz80 regression test,
10828 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10829 Notice z80 compiler fails on examples/test3.c/crc code.
10831 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10833 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

10845 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10846 1) handle multiple send & receives from register bank1
10847 2) ralloc can now allocate DPTR1 to some liveRanges
10849 * src/SDCCsymt.c, src/SDCCsymt.h:
10850 changes to handle multiple sends & receives
10852 * src/SDCCptropt.h:
10853 added some pointer arithmetic optimization
10855 * src/SDCCptropt.c:
10856 added some pointer arithmetic optimizations but not stable yet so not
10857 called from anywhere (will get this working shortly)
10859 * src/SDCCopt.c: fixed for multiple sends & receives
10862 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10863 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10864 set preprocessor defines (depending on options)
10866 * src/SDCCicode.c, src/SDCCicode.h:
10867 changes made to handle multiple sends & receives
10870 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
