3491 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3493 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3494 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3496 One basic decision: e.g. src/clean.mk includes further files. In order
3497 to make this work there are two solutions:
3498 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3499 run configure on them. This way they can use
3500 'include $(srcdir)/port-clean.mk'
3501 - always include clean.mk by the Makefile at the same level. To avoid
3502 that `make clean` tries to include and build Makefile.dep the
3503 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3504 implemented, because now even `make uninstall` doesn't create
3505 Makefile.in. clean.mk could be eliminated by pasting it in
3508 * debugger/mcs51/Makefile.in: build own objects from library sources
3509 (SLIB, SDCC) in current directory
3511 * configure, configure.in: renamed --disable-device-lib-build in
3512 --disable-device-lib; added --enable-doc, the required tools are
3513 searched by configure; added result message; the toolchain for the
3514 belonging ports are now only built, if the port is enabled.
3516 * support/regression/*: all output is written in directory gen, because
3517 the fwk and ports directories don't livet in the build tree using vpath
3519 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3520 --disable-device-lib, added --enable-doc, added section VPATH
3522 * sim/ucsim/configure.in,
3523 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3524 z80 are enabled by default
3526 2006-04-24 Raphael Neider <rneider AT web.de>
3528 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3529 to config word, "pic14_"-prefixed some extern functions
3530 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3531 config word has been found
3532 * src/pic/device.h: added prototypes
3533 * src/pic/pcode.c: added "pic14_"-prefix where needed

3842 call to allocReg, not by manually allocating a new one,
3843 (pic16_assignRegisters): now before going through the register
3844 allocating functions mark all registers as free. This eliminates some
3845 side effects resulting from peephole parser done earlier in the backbone

3908 'xinst' for initial support for Extended Instruction Support,
3909 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3910 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3911 port->fun_prefix anymore (may change later),
3912 (genFunction, genEndFunction): do not store/restore local registers for
3913 _main (this should take care the --main-return command line option in
3915 (genOr): removed some legacy pic-port instructions,
3916 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3917 performing operations with SFR's causes data to be written more than
3918 once to each SFR. Perhaps SFRs should be handled in special cases...
3919 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3921 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3922 into account for stack starting position,
3923 (struct OPTIONS pic16_optionsTable): added command line argument
3924 --extended or -y for Extended Instruction Support,
3925 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3926 (deassignLRs): *** perhaps the most important change, old 'for' code
3927 (commented out for reference), didn't account for some registers which
3928 were left marked 'not free' after a pointer operation. The change
3929 reduces register usage a lot in some cases

6204 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6205 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6206 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6207 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6208 always available in leading double underscore form. The C99 support is
6209 mostly missing, but it's a start.

6289 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6291 * device/lib/printf_large.c: removed inline assembly for portability and
6292 readability. Use printf_fast if speed or size are more important.
6293 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6294 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6296 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6298 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6299 prevent compiler warning
6301 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6303 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6304 moved to level 0 and declared as static. Also they are explicit
6305 placed in access bank. This was necessery because some times they
6306 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6307 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6308 optimizations. Currently only compare to unsigned char is implemented,
6309 * src/pic16/gen.c: added fReturnIdx array,
6310 * (struct resolvedIfx) is moved to gen.h and made public,
6311 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6312 * (aopForSym): added an optimization to directly store in stack of
6313 the operand of a SEND iCode,
6314 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6315 but as registers instead (AOP_REG) using the fReturnIdx array,
6316 * (pic16_freeAsmop): remove the freed register from the
6317 _G.sregsAlloc field,
6318 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6319 a compare of 'WREG',
6320 * (pic16_popGetTempRegCond): changed function prototype, now
6321 function takes also a bitVector argument v which holds the current
6322 set of registers that are allocated for stack access by aopForSym,
6323 registers allocated in aopForSym for accessing stack symbols are not
6324 any more part of the functions usedRegs field,
6325 * (genCall): some times aopOp is called for a stack variable to be
6326 send, aopForSym might perform the push, if this is true make sure
6327 that genCall doesn't push the variable twice by testing _G.resDirect,
6328 * (genFunction): changed testing for unspecified interrupt number
6329 from 256 to INTNO_UNSPEC,
6330 * modified selection scheme of frame pointer generation. Previously
6331 if function did use local registers a frame pointer was generated,
6332 now a frame pointer is generated only if function has arguments
6333 (that need PLUSW2 register access), or has stack arguments, or the
6334 compiler is not instructed to omit the frame pointer,
6335 * (genEndFunction): before restoring local registers that were saved
6336 in the function preamble, also restore the registers that *might*
6337 have been allocated for stack access,
6338 * (genRet): removed some old comments,
6339 * (genCmp, the active (RN's) version): added a call to the
6340 pic16_genCmp_special function to perform the compare with a more
6341 robust and optimized way,
6342 * (genInline): a feature has been added in inline code generation,
6343 which allows a wildcard variable substitution when writing inline
6344 assembly. Code is incomplete and experimental therefore undocumented,
6345 * (genCast): changed order of aopOp for result and right to allow
6346 aopForSym to directly load the result if possible,
6347 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6348 perform an optimized compare on some selected special occasions,
6349 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6350 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6351 generate an IVT any more,
6352 * src/pic16/main.c (pic16_optionsTable): added command line option
6354 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6355 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6357 * src/pic16/NOTES: Raphael Neider added in list of active developers
6358 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6359 jumptable_end to prevent bug #,
6360 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6361 inCond and outCond fields,
6362 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6363 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6364 turn off register spilling,
6365 * (packRegsForOneUse): synced with other ports' versions although it
6366 is not used currently,
6367 * (pic16_packRegisters): added an optimization while reading
6368 structure bitfields, some registers may be saved (malloc code is
6369 decreased by 80 bytes)
6371 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6373 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6374 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6375 this can be optimized more?
6377 2005-03-10 Raphael Neider <rneider AT web.de>
6379 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6380 genNearPointerGet): (hopefully) fixed access to bitfields via
6381 pointers (p->bitN = x; and x = p->bitN; failed)
6383 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6426 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
6427 to keep the correct label reference count when adding/removing references
6428 to labels. A peephole file using this is appended to patch #1144962.
6430 2005-02-14 Raphael Neider <rneider AT web.de>

7015 Adding support for replacing ljmps with sjmps in jumptables
7016 generated for switch statements. For now you need to set the
7017 environment variable SDCC_SJMP_JUMPTABLE to enable this.
7018 Now 4 algorithms for mcs51 jumptable generation are used:
7019 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
7020 addresses loaded pc-relative for up to 112 cases and stack-pushing
7021 target addresses loaded with offset from dptr for up to 256 cases.

7051 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7053 * added libc directory. The current version of LibC contains string
7054 functions, ctype functions and macros and some functions of the
7055 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7056 be extensively tested in the future. Standard disclaimer here.
7057 Library is not automatically build yet. But one can build it by
7058 invoking 'make' inside the libc directory.

7069 * (pic16_storeForReturn): optimized return of 0,
7070 * (genCmp): experimental code for new genCmp which uses PIC18's
7071 special compare&skip instructions. Initial tests fail some times
7072 with variables grater than 1 byte in size, so new code is disabled,
7073 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7075 * (genCast): began a fix to optimize the casting of a bit to another
7076 bit, now assigning a bitfield to another bitfield will fail, sorry,
7077 * src/pic16/main.c: disabled the use of lr-support feature,
7078 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

7085 and 1 for banking instruction,
7086 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7087 caused stop processing pCodes after a inline assembly block,
7088 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
7089 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
7090 registers when it shouldn't,
7091 * src/pic16/ralloc.c (allocReg): add preliminary support for
7092 supporting a limited set of temporary registers,
7094 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7096 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
7097 genDataPointerSet): ensure assignments always copy in MSB to LSB
7099 (loadRegFromAop): recognize CLRH optimization,
7100 (genFunction): optimize RECEIVE iCodes in reentrant functions
7102 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10013 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
10015 * src/SDCCast.c: added an additional type flow in decorateType() of
10016 opposite direction, see feature request #860006; it's enabled at runtime
10017 by setting the environment variable SDCC_NEWTYPEFLOW

10051 * src/pic/ralloc.h: applied patch from Slade Rich;
10052 added support for multiple code pages and multiple RAM banks on the
10053 PIC 14 port. The ASM files now no longer simply assume all the
10054 code / RAM are in the same page / bank. This means the linker can
10055 safely allocate code/RAM of separate ASM files to different pages/banks.
10056 * doc/sdccman.lyx: added Slade's tips

10099 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10101 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10102 loaded with the linker search paths (-L arguments) and the libraries
10103 to be linked with the current source (-l arguments). Changes
10104 currently will affect only the pic16 port.
10105 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10106 include path the port specific paths and port specific libraries,
10107 * gplink command now contains the $3 argument,
10108 * src/pic16/device.h,
10109 * src/pic16/device.c,: structure PIC_device is made public and
10110 renamed to PIC16_device, the same for variable Pics which is renamed
10111 to Pics16. Updated all references to them.

10123 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10125 Documenting changes from previous commits.
10126 * configure.in (version 1.56),
10127 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10128 when generating output files to configure the pic16 library,
10129 but now I've commented it out, since gputils aren't installed in the
10130 SF compile farm, so library won't compile
10132 * device/lib/Makefile.in (version 1.56): initially I've added in
10133 target 'all' the prerequestive 'model-pic16' so it compiled the
10134 pic16 library, but now I've commented it out for the same reasons
10136 * added targets 'model-pic16' and 'objects-pic16' to compile the
10138 * added target 'port-specific-objects-pic16' to handle the
10139 generated libraries and copy them into the build/ directory
10140 * added target 'clean-intermediate-pic16' to clean intermediate
10141 files into pic16 directory
10142 * in target 'installdirs' added line to create directory pic16 in
10143 the installation path
10145 * device/include/Makefile.in (version 1.11): in target 'install'
10146 added lines to copy all header files to installation path,
10147 * in target 'installdirs' added line create directory for pic16
10148 headers in the installation path

10163 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10164 option so that it actually works. Made it specific to the z80, since
10165 the gbz80 doesn't have these kinds of I/O ports.
10167 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10200 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10202 Added portion of GNU PIC Library under the directory
10203 device/include/pic16 and device/lib/pic16. These files

10205 The directory is initialized via configure from toplevel.
10207 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10209 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10210 the spilllocations to be compared correctly

10433 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10435 PIC16 port related changes:
10436 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10437 added variable stackPos,
10439 * gen.c: genCall, assignResultValue: added support for
10440 pushing/retrieving function parameters to/from stack,
10441 genFunction,genEndFunction: setup stack frame for the
10442 generated function,
10443 genAddrOf: will be changed according to bug 863624
10445 * added files genutils.c and genutils.h which contain gen*
10446 debugged and optimised functions extracted from gen.c
10448 * glue.c: added variable 'externs' which holds extern symbols,
10449 pic16emitRegularMap: is modified to properly handle relocatable
10450 symbols under the new scheme,
10451 pic16createInterruptVect: is modified
10452 pic16printPublics: is modified to emit 'global' assembler directives,
10453 added pic16_printExterns to print extern symbols,
10454 pic16glue: initializes stack/frame pointer in the beginning of
10455 the assembly output. Temporary hack, will be corrected later,
10456 because gplink yet does not support stack and SDCC does not
10457 yet support a type of crt0.o object to create the final binary.
10459 * Removed many lines that contain 8051 legacy code.
10460 * The code is finally placed under a 'code' directive.
10461 * Added port specific options.
10463 * _process_pragma: simplified since now we do not need *special*
10464 include file to define SFR registers. But a separate header
10465 will be needed. This will be developed later.
10466 * _pic16_parseOptions: added, parses port specific options:
10467 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10468 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10469 --preplace-udata-with=
10471 * _pic16_setDefaultOptions: modified to initialize section names,
10472 but hack is temporarly out of order since it needs improvement.
10473 * _pic16_genAssemblerPreamble: configuration words are emitted by
10474 their address instead of their name. This part is incomplete and
10475 supports only the 18Fxx2 devices. Other devices will emit an error
10476 during assembly since they do not contain the same set of config
10478 * _pic16_genIVT: is modified,
10480 * pcode.c: added definitions for some hardware registers that are needed
10482 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10483 All PCI entries are updated. Now LFSR is supported.
10484 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10485 * added pic16_newpCodeOpLit2 to support instructions with
10486 two literal arguments
10487 * pic16_pCode2str: corrected code that emits assembler instructions
10488 with two literal operands and those that have an access bit modifier
10489 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10490 this fixes a bug which caused some labels to be lost, when an
10491 assembler directive was added, i.e. banksel,
10492 * pic16_FixRegisterBanking: improved logic that causes the insertion
10494 * InlineFunction: functions that are called once, are not any more
10495 inlined. This can be a port option in the future,
10497 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10499 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10500 hold the corresponding uninitialized symbols,
10501 * pic16_allocProcessorRegister: registers have explicit marked the
10503 * pic16_allocInternalRegister: registers are explicit marked as
10505 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10506 processing list, so bit registers were lost,
10509 * ralloc.h: added field 'accessBank' and original symbol operand
10510 in register definition,
10511 * removed the field isMapped from register definition,
10513 ** Several functions have been removed from various sources:
10514 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10515 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10516 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10517 pic16_assignRelocatableRegisters
10519 ** others have been introduced:
10520 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10521 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10523 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10525 * support/scripts/inc2h.pl: changed definition of BIT_AT
10526 to emit 'sbit at' instead of 'bit at'. This was a request.
10528 PIC16 port related preliminary changes:
10529 * gen.c: prefixed function popRegFromString with
10530 pic16_ and all references to it corrected
10531 * pcode.c: all pic16_pc_* hardware registers prefixed
10532 with underscore (_),
10533 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10534 * ralloc.c: newReg(): when register is REG_SFR then
10535 set address to rIdx,
10536 pic16_allocProcessorRegister(): marks register wasUsed=0
10537 pic16_writeUsedRegs(): added a call to assign processor
10538 registers via pic16_assignFixedRegisters
10540 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10542 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10543 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10544 variables in unused register banks. Also the SSEG is placed
10545 wherever there is enough space for it, and IDATA can be anywhere
10546 in internal RAM. For now compile using -Wl-Y[stack_size].
10547 The mem file is different for this option as well, since it
10548 makes no sense of talking about DSEG lenght.
10550 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10552 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10553 in certain cases, e.g. when ROM assignment, patch provided
10554 from Albert den Haan.
10556 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10797 * src/SDCCast.c (decorateType): disabled a transformation I added in
10798 revision 1.188 (access to fields of a structure at an absolute address);
10799 it breaks with bitfields, extern declarations, and gcse analysis.
10800 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10801 could be assigned through a pointer, so don't complain.
10802 * src/SDCCast.c (astErrors),

11384 genCodePointerGet, genGenPointerGet, genFarPointerSet,
11385 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
11386 (ralloc doesn't intentionally do this now, but perhaps later)
11387 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
11388 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some
11389 register positioning bugs (Fixed bug #762602 and #795325)

11398 trying to fclose a FILE* that was already closed.
11400 2003-09-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11402 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
11403 of const struct should be treated as if const themselves)
11405 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
11407 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

11422 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11423 and restore of EA so that stack offsets to parameters are
11424 correct when using both critical and reentrant/stack-auto.
11425 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
11426 size (can be triggered in error if sloc is shared between
11427 different sized objects)
11428 * device/include/float.h: fixed macros to explicitly use
11429 unsigned long where needed
11431 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>
11433 Feature req. 799831: added code to allow nesting of critical functions

11437 2003-09-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11439 * src/SDCCsymt.c (sclsFromPtr),
11441 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11442 support for standard C idiom of memory mapped variables; for
11443 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11444 to xdata int at 0x1234 tempvar = 1.
11445 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11446 provided by Akiya ISHIDA

11458 2003-09-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11460 * src/z80/gen.c (genXor): Fixed bug #805445
11462 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11464 Fixed bug #621531 (const & volatile confusion in the type chain).
11465 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11466 refer to the const or volatile state of the pointer itself.
11478 * src/pic16/ralloc.c
11479 * support/regression/tests/const.c
11481 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11483 When checking for duplicated modules, use absolute paths
11484 instead of relative paths. Files changed:

11525 reported in bug #800609
11527 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
11529 * Top header beautifications in src/pic16 directory:
11530 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
11531 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11532 pcoderegs.h, ralloc.c, ralloc.h
11533 * main.c: added top header and GPL license notice
11534 * pcode.c: fixed the if-conditional warning
11536 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11538 * device/lib/_mullong.c: replaced int by short for gcc
11540 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11542 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11543 and JUMPTABLE iCodes properly now (worked by accident before)
11544 * src/mcs51/gen.c (leftRightUseAcc),
11545 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11546 iCode properly now. Use getSize instead of nRegs since a & b
11547 aren't part of the nRegs tally.
11549 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11551 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11553 before instructions that use the _STATUS register
11555 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
11557 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
11558 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
11559 fetching of the pointer
11560 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11561 copied from genNearPointerSet()
11562 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11563 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11564 If they pop r0/r1 they must be called in the opposite order than aopOp().
11565 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11566 (resp. --stack-auto), prepared for --xstack
11568 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11570 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11572 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11574 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11575 these ports have their own __sdcc_external_start()
11577 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11579 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11580 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11581 type for bits was changed. It resulted in bit variables becoming
11582 global, which is not permitted in PIC 14 assembly output.
11584 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11586 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11588 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11590 Z80 and MCS51 linkers complaint if a public symbol is defined
11591 in more than one library module:
11595 * as/mcs51/Makefile.in
11597 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11599 A few small changes that speed up the peephole optimizer.
11603 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11605 Try to make the peephole optimizer smarter by maintaining
11606 an association between the assembly source code and the
11607 iCodes that originated them. Put this information to use
11608 with a new peephole rule condition "notVolatile" so that
11609 the rules can be aggressive yet still safe.
11614 * src/mcs51/peeph.def
11616 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11620 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11621 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11622 if the left or right operand symbols have the accuse flag set.
11624 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11626 Changed the type of the result of the ! (NOT) operator to char;
11627 previously it returned the same type as the source. This allows
11628 us to eliminate all the genFloatNot functions (all of its target
11629 implementations were very buggy) since !float can use the same
11632 * src/SDCCicode.c (ast2iCode): ! returns char
11633 * src/mcs51/gen.c (genNot, genNotFloat),
11634 * src/ds390/gen.c (genNot, genNotFloat),
11635 * src/z80/gen.c (genNot, genNotFloat),
11636 * src/pic/gen.c (genNot, genNotFloat),
11637 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11639 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11641 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11642 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11643 during interrupts. Ensure WSAVE is located at a shared bank address.
11644 2. Fixed page selection in some places
11645 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11646 the registers name strings.
11647 4. Fixed "signed / unsigned compare" compiler warnings.
11648 5. The PIC port manages its own allocation of the general purpose
11649 registers, but makes no attempt to reuse them. As a result when
11650 compiling it soon runs out of general purpose registers. Some
11651 additional code was added to the files pcode.c and device.c to walk
11652 through the function call tree and rename the registers so that they
11662 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11663 genPlus() & genMinus() when the result is the same as left or right
11665 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11667 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11669 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11671 Made bitfield a distinct type from bit so that bitfields
11672 convert as per ANSI C and bits retain their traditional
11673 boolean style behaviour. Implemented bitfield support in
11681 * src/ds390/gen.c: bit v bitfield split
11682 * src/z80/gen.c: New support for bitfields
11683 * support/regression/tests/bitfields.c: reenabled z80,
11686 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11688 Rules 246.x, 247.x relate to bitfields, the others speed up
11689 access to xdata mapped I/O devices.
11691 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11693 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11695 Cleaned up genPackBits and genUnpackBits and added two helper
11696 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11697 for literal assignments in genPackBits (thanks to Frieder for
11703 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11705 Fixed bug #748310 (pointer to function type mishandled when the
11706 function name is omitted). Also fixed a SIGSEGV when a function
11707 attribute (reentrant, etc) is used on a non-function or on a
11708 function but misplaced before the parameter list.
11710 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11712 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11713 * support/Util/SDCCerr.h,
11714 * support/Util/SDCCerr.c: Added func attr misuse error msg
11716 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11718 Fixed bug #787649 by anonymous
11719 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11720 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11722 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11724 Fixed numerous bitfield problems.
11726 * src/SDCC.y: More bitfield related error checking
11728 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
11729 * support/Util/SDCCerr.h,
11730 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11731 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11732 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11733 * support/regression/tests/bitfields.c: tests added
11735 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11737 Made the constant following the "interrupt" keyword optional. If
11738 omitted, the function will not automatically be given an entry
11739 in the interrupt vector table (similar to #pragma NOIV, but
11740 less syntacticly kludgy). The interrupt number is also now
11741 range checked. Also fixed a bug in the high order bit example

11749 * support/Util/SDCCerr.h
11752 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11754 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11755 * src/SDCCicode.c (operandOperation): rewritten some ops
11756 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11757 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11759 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11760 be re-activated by defining REDUCE_LITERALS)
11761 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11762 unsigned, but are signed by default
11763 * src/SDCCval.c (constVal): rearranged
11764 * src/SDCCval.c (valMod): preliminary fix
11765 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11803 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11805 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11806 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11807 constants are unsigned; added recognition of "u" flag for unsigned
11808 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11809 * src/SDCCval.c (valDiv, valMod): fixed signdness
11810 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11811 signedness of modulo, left and right shift

11854 * support/librarian/configure.in
11855 * support/librarian/config_in.h
11856 * support/librarian/Makefile.in
11858 Hopefully these ones built the librarian and the rest of sdcc properly:

11862 Messed up 'configure', so revert to previous version:
11866 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
11868 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
11869 there, while the mantissa of a double is "only" 53 bits wide.
11871 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

12273 support for the PIc16 port in the ports table, when executing
12274 the compiler with no port specified on command line, a default
12275 port is selected with the new macro DEFAULT_PORT which is
12276 defined in port.h, in setDefaultOptions() linkOptions is removed
12277 from initialization assignment, since now it is a set,
12278 parseCmdLine uses setParseWithComma for linkOptions, in
12279 linkEdit() linkOptions are accessed with new function indexSet()
12280 which returns the i'th item of a set variable. See SDCCset.c, in
12281 linkEdit() when calling buildCmdLine(), added linkOptions as
12282 last argument. Now users can pass arguments to gplink via the

12297 gpasm complaining and test the linkage with gplink, _linkCmd and
12298 _asmCmd changed to be more gplink and gpasm friendly
12299 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12300 produced an error when parsed, peep rule 12 is added to utilize
12301 movff, but it is commented out since the pCode does not support
12302 yet a command with 2 address arguments

13361 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13362 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13364 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13365 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13367 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13369 * in /sdcc/as/mcs51/ changed these files in order to create an
13370 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13371 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13372 following files to include the previous two files: aslink.dsp,
13373 Makefile.aslink, Makefile.bcc, and Makefile.in.
13375 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13376 .adb instead of .cdb
13378 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13380 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13381 value from option --iram-size.
13383 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13385 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13388 2002-09-18 <wiml AT hhhh.org>
13390 * SDCClrange.h: exposed setFromRange() and setToRange()
13391 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13392 packRegsForAccUse() (bug 542397)
13393 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13394 multiple times and emitting the fetch operations more than once
13395 added aopGetUsesAcc() function to allow binary operators to
13396 fetch their operands in the correct order; made genMinus() emit
13397 compact code for X = LITERAL - Y
13399 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13400 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13401 sprintf() in line 1267.
13403 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13404 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13407 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13408 Changes to aslink (All the changes are marked with 'JCF'):
13410 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13413 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13414 area BSEG. Also moves, if possible, the DATA area down into the internal
13415 ram so more space is available.
13417 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13420 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13421 not bytes. Function summary() which creates a memory usage summary
13422 file with extension .mem. Reports of overlaping stack and small stack
13423 size. If the space for the stack is less than 16 bytes aslink trows a
13426 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13427 the 8051. Option 'y' for memory summary output file.
13429 Changes to sdcc (All the changes are marked with 'JCF'):
13431 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13433 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13434 overlaying area for it (uses RegBankUsed[4]).
13436 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13437 bank zero as used by default. By default aslink locates the stack
13438 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13439 the creation of the .mem file. Delegates the allocation of data area
13440 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13441 the begining of the stack area to aslink.
13443 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13444 glue() in SDCCglue.c creates an area for it.
13446 2002-09-03 Borut Razem <borut.razem AT siol.net>
13447 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13448 sdcc/src/pic/glue.c:
13449 introduced atexit() handler for teporay files removal in case of
13450 errors, assertions, ...
13452 2002-08-29 Borut Razem <borut.razem AT siol.net>
13453 * sdcc/support/cpp2/auto-host_vc_in.h:
13454 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13455 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13456 Maybe there is a similar problem with BORLANDC? It should be checked!
13458 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13459 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13460 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13461 was not executed, and the compiler (cl) launched a warning:
13462 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13464 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13465 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13467 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13468 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13470 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13471 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13472 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13473 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13474 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13475 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13476 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13477 - added Release configuration in VS projects
13478 - review of compiler an linker options
13479 - VC .exe files are generated in bin_vc directory, not to interfere
13480 with binaries generated from other projects (cygwin, mingw, bcc ...)
13482 * sdcc/src/yacc.dsp: added
13484 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13485 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13486 and insert the version number definitions from .version
13488 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13490 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13491 added - genarate auto-host.h using auto-host_vc_in.h as template
13494 removed from CVS, generated automatically
13496 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13497 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13499 2002-08-11 Borut Razem <borut.razem AT siol.net>
13500 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13502 2002-08-10 Borut Razem <borut.razem AT siol.net>
13503 * src/SDCCmain.c (main):
13504 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13505 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13506 The consequence was that some temporary files were not removed.
13509 unification of code in functions tempfilename() and tempfile():
13510 function tempnam() is defined in Visual Studio 6.0 and .NET
13512 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13514 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13515 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13516 - removed compiler command line option /WX: Treats all warnings as errors
13517 - update a list of source files, included into the project
13519 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13520 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13521 changed project type to Generic Project so that can be correcly converted to VS.NET project
13523 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13525 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13527 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13529 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13530 added return 0 statements after assert() to make compiler happy
13532 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13533 added newline in the def file to keep MSC compiler satisfied
13535 * sdcc/src/z80/gen.c:
13536 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13537 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13538 - solved MSC error in function aopDump()
13540 * sdcc_vc.h: define PREFIX as "\\sdcc"
13542 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13543 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13546 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13547 - Rewrote the register banking algorithm.
13548 - Added pCode live-range analysis to registers (for now, only non-used and
13549 singly-used registers optimized away)
13551 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13553 * 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.

13582 2002-03-28 Johan Knol <johan AT balder>
13584 * src/SDCCval.c: fixed bug #532436
13586 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13588 Added "char *Processor" field to the port structure.
13591 Added -p option. Allows port dependent processor to be specified.
13594 Initialized the new field char *Processor field to NULL in all ports
13597 Compiler generated registers for interrupt context saving
13598 were not getting allocated.
13600 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13603 Fixed left shift. Will promote the left side of a left shift
13604 if a) left shifting more than size of operand or b) when assigned
13605 to something size > size of left side
13607 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13609 tons of changes. Register allocation has been
13610 rewritten. Added customization for the various PICs. Flow
13611 analysis is restructured. ...
13613 * src/pic/device.h:
13616 * src/pic/device.c:
13617 Added. device.c is a PIC port hack to accomodate variations
13620 2002-03-13 Michael Hope <michaelh AT vroom>
13622 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13624 2002-03-04 johanknol <johanknol AT manik>
13626 * /src/SDCCval.c: fixed
13628 const unsigned char arr[][2] = { { 0, 1 } };
13629 t18.c:1: error: Initializer element is not constant
13631 2002-03-04 bela <bela AT manik>
