3548 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3549 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3551 One basic decision: e.g. src/clean.mk includes further files. In order
3552 to make this work there are two solutions:
3553 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3554 run configure on them. This way they can use
3555 'include $(srcdir)/port-clean.mk'
3556 - always include clean.mk by the Makefile at the same level. To avoid
3557 that `make clean` tries to include and build Makefile.dep the
3558 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3559 implemented, because now even `make uninstall` doesn't create
3560 Makefile.in. clean.mk could be eliminated by pasting it in
3563 * debugger/mcs51/Makefile.in: build own objects from library sources
3564 (SLIB, SDCC) in current directory
3566 * configure, configure.in: renamed --disable-device-lib-build in
3567 --disable-device-lib; added --enable-doc, the required tools are
3568 searched by configure; added result message; the toolchain for the
3569 belonging ports are now only built, if the port is enabled.
3571 * support/regression/*: all output is written in directory gen, because
3572 the fwk and ports directories don't livet in the build tree using vpath
3574 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3575 --disable-device-lib, added --enable-doc, added section VPATH
3577 * sim/ucsim/configure.in,
3578 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3579 z80 are enabled by default
3581 2006-04-24 Raphael Neider <rneider AT web.de>
3583 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3584 to config word, "pic14_"-prefixed some extern functions
3585 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3586 config word has been found
3587 * src/pic/device.h: added prototypes
3588 * src/pic/pcode.c: added "pic14_"-prefix where needed
3589 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3591 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

3605 fixes #1469504 and #1474602,
3606 (pCodeRegOptimizeRegUsage): fixed typo in comment

3879 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3880 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

3896 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3897 call to allocReg, not by manually allocating a new one,
3898 (pic16_assignRegisters): now before going through the register
3899 allocating functions mark all registers as free. This eliminates some
3900 side effects resulting from peephole parser done earlier in the backbone

3925 (freeAsmop): decrement asmop.allocated and check for zero instead of
3927 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3928 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

3950 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3952 2006-03-06 Borut Razem <borut.razem AT siol.net>
3954 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3955 made the linker quiet
3957 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3959 * src/pic16/gen.c (genPcall): fixed bug #1443644
3960 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3961 which dumps before the function entry point a data byte which represents
3962 the number of the local variables used by the specified function, added
3963 'xinst' for initial support for Extended Instruction Support,
3964 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3965 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3966 port->fun_prefix anymore (may change later),
3967 (genFunction, genEndFunction): do not store/restore local registers for
3968 _main (this should take care the --main-return command line option in
3970 (genOr): removed some legacy pic-port instructions,
3971 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3972 performing operations with SFR's causes data to be written more than

3979 --extended or -y for Extended Instruction Support,
3980 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3981 (deassignLRs): *** perhaps the most important change, old 'for' code
3982 (commented out for reference), didn't account for some registers which
3983 were left marked 'not free' after a pointer operation. The change
3984 reduces register usage a lot in some cases

6259 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6260 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6261 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6262 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6263 always available in leading double underscore form. The C99 support is

6344 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6346 * device/lib/printf_large.c: removed inline assembly for portability and
6347 readability. Use printf_fast if speed or size are more important.
6348 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6349 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6351 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6353 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6354 prevent compiler warning
6356 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6358 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6359 moved to level 0 and declared as static. Also they are explicit
6360 placed in access bank. This was necessery because some times they
6361 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6362 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6363 optimizations. Currently only compare to unsigned char is implemented,
6364 * src/pic16/gen.c: added fReturnIdx array,
6365 * (struct resolvedIfx) is moved to gen.h and made public,
6366 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6367 * (aopForSym): added an optimization to directly store in stack of
6368 the operand of a SEND iCode,
6369 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6370 but as registers instead (AOP_REG) using the fReturnIdx array,
6371 * (pic16_freeAsmop): remove the freed register from the
6372 _G.sregsAlloc field,
6373 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6374 a compare of 'WREG',
6375 * (pic16_popGetTempRegCond): changed function prototype, now
6376 function takes also a bitVector argument v which holds the current
6377 set of registers that are allocated for stack access by aopForSym,
6378 registers allocated in aopForSym for accessing stack symbols are not
6379 any more part of the functions usedRegs field,
6380 * (genCall): some times aopOp is called for a stack variable to be
6381 send, aopForSym might perform the push, if this is true make sure
6382 that genCall doesn't push the variable twice by testing _G.resDirect,
6383 * (genFunction): changed testing for unspecified interrupt number
6384 from 256 to INTNO_UNSPEC,
6385 * modified selection scheme of frame pointer generation. Previously
6386 if function did use local registers a frame pointer was generated,
6387 now a frame pointer is generated only if function has arguments
6388 (that need PLUSW2 register access), or has stack arguments, or the
6389 compiler is not instructed to omit the frame pointer,
6390 * (genEndFunction): before restoring local registers that were saved
6391 in the function preamble, also restore the registers that *might*
6392 have been allocated for stack access,
6393 * (genRet): removed some old comments,
6394 * (genCmp, the active (RN's) version): added a call to the
6395 pic16_genCmp_special function to perform the compare with a more
6396 robust and optimized way,
6397 * (genInline): a feature has been added in inline code generation,
6398 which allows a wildcard variable substitution when writing inline
6399 assembly. Code is incomplete and experimental therefore undocumented,
6400 * (genCast): changed order of aopOp for result and right to allow
6401 aopForSym to directly load the result if possible,
6402 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6403 perform an optimized compare on some selected special occasions,
6404 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6405 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6406 generate an IVT any more,
6407 * src/pic16/main.c (pic16_optionsTable): added command line option
6409 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6410 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6412 * src/pic16/NOTES: Raphael Neider added in list of active developers
6413 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6414 jumptable_end to prevent bug #,
6415 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6416 inCond and outCond fields,
6417 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6418 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6419 turn off register spilling,
6420 * (packRegsForOneUse): synced with other ports' versions although it
6421 is not used currently,
6422 * (pic16_packRegisters): added an optimization while reading
6423 structure bitfields, some registers may be saved (malloc code is
6424 decreased by 80 bytes)
6426 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6428 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6429 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6430 this can be optimized more?
6432 2005-03-10 Raphael Neider <rneider AT web.de>
6434 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6435 genNearPointerGet): (hopefully) fixed access to bitfields via
6436 pointers (p->bitN = x; and x = p->bitN; failed)
6438 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
6440 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
6442 2005-03-09 Raphael Neider <rneider AT web.de>
6444 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
6446 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
6448 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
6449 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
6450 (regTypeNum): set REG_BIT type if necessary
6451 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

7070 Adding support for replacing ljmps with sjmps in jumptables
7071 generated for switch statements. For now you need to set the
7072 environment variable SDCC_SJMP_JUMPTABLE to enable this.
7073 Now 4 algorithms for mcs51 jumptable generation are used:
7074 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
7075 addresses loaded pc-relative for up to 112 cases and stack-pushing
7076 target addresses loaded with offset from dptr for up to 256 cases.

7106 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7108 * added libc directory. The current version of LibC contains string
7109 functions, ctype functions and macros and some functions of the
7110 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7111 be extensively tested in the future. Standard disclaimer here.
7112 Library is not automatically build yet. But one can build it by
7113 invoking 'make' inside the libc directory.

7124 * (pic16_storeForReturn): optimized return of 0,
7125 * (genCmp): experimental code for new genCmp which uses PIC18's
7126 special compare&skip instructions. Initial tests fail some times
7127 with variables grater than 1 byte in size, so new code is disabled,
7128 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7130 * (genCast): began a fix to optimize the casting of a bit to another
7131 bit, now assigning a bitfield to another bitfield will fail, sorry,

7140 and 1 for banking instruction,
7141 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7142 caused stop processing pCodes after a inline assembly block,
7143 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

7145 registers when it shouldn't,
7146 * src/pic16/ralloc.c (allocReg): add preliminary support for
7147 supporting a limited set of temporary registers,
7149 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7151 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

7155 (genFunction): optimize RECEIVE iCodes in reentrant functions
7157 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10107 added support for multiple code pages and multiple RAM banks on the
10108 PIC 14 port. The ASM files now no longer simply assume all the
10109 code / RAM are in the same page / bank. This means the linker can
10110 safely allocate code/RAM of separate ASM files to different pages/banks.

10154 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10156 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10157 loaded with the linker search paths (-L arguments) and the libraries
10158 to be linked with the current source (-l arguments). Changes
10159 currently will affect only the pic16 port.
10160 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10161 include path the port specific paths and port specific libraries,
10162 * gplink command now contains the $3 argument,
10163 * src/pic16/device.h,
10164 * src/pic16/device.c,: structure PIC_device is made public and
10165 renamed to PIC16_device, the same for variable Pics which is renamed

10180 Documenting changes from previous commits.
10181 * configure.in (version 1.56),
10182 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10183 when generating output files to configure the pic16 library,
10184 but now I've commented it out, since gputils aren't installed in the
10185 SF compile farm, so library won't compile
10187 * device/lib/Makefile.in (version 1.56): initially I've added in
10188 target 'all' the prerequestive 'model-pic16' so it compiled the
10189 pic16 library, but now I've commented it out for the same reasons
10191 * added targets 'model-pic16' and 'objects-pic16' to compile the
10193 * added target 'port-specific-objects-pic16' to handle the
10194 generated libraries and copy them into the build/ directory
10195 * added target 'clean-intermediate-pic16' to clean intermediate
10196 files into pic16 directory
10197 * in target 'installdirs' added line to create directory pic16 in
10198 the installation path
10200 * device/include/Makefile.in (version 1.11): in target 'install'
10201 added lines to copy all header files to installation path,
10202 * in target 'installdirs' added line create directory for pic16
10203 headers in the installation path

10216 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10218 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10219 option so that it actually works. Made it specific to the z80, since
10220 the gbz80 doesn't have these kinds of I/O ports.
10222 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10248 via literal number. The symbol is placed in the corresponding
10249 position of the data ram
10250 * (pic16_dump_section): relocatable and absolute uninitialized
10251 data are now emitted in sorted order to reduce section naming,

10255 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10257 Added portion of GNU PIC Library under the directory
10258 device/include/pic16 and device/lib/pic16. These files
10259 contain the declarations of SFRs for the PIC18Fxx2 devices.
10260 The directory is initialized via configure from toplevel.
10262 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10264 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10265 the spilllocations to be compared correctly
10267 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

10290 all over. Telling LaTeX to be less strict with word spacing
10291 to better keep the right margin. Changed some notes about
10292 maintainance of the ports in section 3.2.1 - is it OK like this?

10437 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10439 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
10441 * support/valdiag/tests/overflow.c: added
10442 * src/SDCCast.c (decorateType),
10443 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
10444 LEFT_OP (left shift)
10446 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10448 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
10449 (default behaviour).
10451 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10453 A python script to validate compiler diagnostic messages. It can be
10454 used to verify that sdcc complains about bad c source code and
10455 gives a good location of the error.
10456 * support/valdiag/Makefile,
10457 * support/valdiag/valdiag.py,
10458 * support/valdiag/tests/*
10460 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10462 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
10463 * src/SDCCsymt.c (newEnumType),
10465 * support/Util/SDCCerr.c,
10466 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
10468 * support/regression/tests/enum.c: added test for enum values that
10469 require at least 2 bytes of storage.
10471 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10473 * src/common.h: added ifndef/define/endif macros
10474 around the header file.
10475 Bug reported from Jesus Calvino-Fraga
10477 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10479 * sdcc.spec: updated
10480 * device/include/Makefile.in: don't install CVS directories
10481 * device/lib/Makefile.in: added removal of CVS directories after install
10482 * doc/Makefile: fixed install, added local_icons
10483 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
10484 * src/mcs51/gen.c (genRightShift): fixed bug #870788
10485 * src/ds390/gen.c (genRightShift): fixed bug #870788
10486 * src/SDCCast.c (decorateType): fixed bug #870781
10488 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10490 PIC16 port related changes:
10491 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10492 added variable stackPos,
10494 * gen.c: genCall, assignResultValue: added support for
10495 pushing/retrieving function parameters to/from stack,
10496 genFunction,genEndFunction: setup stack frame for the
10497 generated function,
10498 genAddrOf: will be changed according to bug 863624
10500 * added files genutils.c and genutils.h which contain gen*
10501 debugged and optimised functions extracted from gen.c
10503 * glue.c: added variable 'externs' which holds extern symbols,
10504 pic16emitRegularMap: is modified to properly handle relocatable
10505 symbols under the new scheme,
10506 pic16createInterruptVect: is modified
10507 pic16printPublics: is modified to emit 'global' assembler directives,
10508 added pic16_printExterns to print extern symbols,
10509 pic16glue: initializes stack/frame pointer in the beginning of
10510 the assembly output. Temporary hack, will be corrected later,
10511 because gplink yet does not support stack and SDCC does not
10512 yet support a type of crt0.o object to create the final binary.
10514 * Removed many lines that contain 8051 legacy code.
10515 * The code is finally placed under a 'code' directive.
10516 * Added port specific options.
10518 * _process_pragma: simplified since now we do not need *special*
10519 include file to define SFR registers. But a separate header
10520 will be needed. This will be developed later.
10521 * _pic16_parseOptions: added, parses port specific options:
10522 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10523 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10524 --preplace-udata-with=
10526 * _pic16_setDefaultOptions: modified to initialize section names,
10527 but hack is temporarly out of order since it needs improvement.
10528 * _pic16_genAssemblerPreamble: configuration words are emitted by
10529 their address instead of their name. This part is incomplete and
10530 supports only the 18Fxx2 devices. Other devices will emit an error
10531 during assembly since they do not contain the same set of config
10533 * _pic16_genIVT: is modified,
10535 * pcode.c: added definitions for some hardware registers that are needed
10537 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10538 All PCI entries are updated. Now LFSR is supported.
10539 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10540 * added pic16_newpCodeOpLit2 to support instructions with
10541 two literal arguments
10542 * pic16_pCode2str: corrected code that emits assembler instructions
10543 with two literal operands and those that have an access bit modifier
10544 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10545 this fixes a bug which caused some labels to be lost, when an
10546 assembler directive was added, i.e. banksel,
10547 * pic16_FixRegisterBanking: improved logic that causes the insertion
10549 * InlineFunction: functions that are called once, are not any more
10550 inlined. This can be a port option in the future,
10552 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10554 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10555 hold the corresponding uninitialized symbols,
10556 * pic16_allocProcessorRegister: registers have explicit marked the
10558 * pic16_allocInternalRegister: registers are explicit marked as
10560 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10561 processing list, so bit registers were lost,
10564 * ralloc.h: added field 'accessBank' and original symbol operand
10565 in register definition,
10566 * removed the field isMapped from register definition,
10568 ** Several functions have been removed from various sources:
10569 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10570 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10571 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10572 pic16_assignRelocatableRegisters
10574 ** others have been introduced:
10575 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10576 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10578 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10580 * support/scripts/inc2h.pl: changed definition of BIT_AT
10581 to emit 'sbit at' instead of 'bit at'. This was a request.
10583 PIC16 port related preliminary changes:
10584 * gen.c: prefixed function popRegFromString with
10585 pic16_ and all references to it corrected
10586 * pcode.c: all pic16_pc_* hardware registers prefixed
10587 with underscore (_),
10588 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10589 * ralloc.c: newReg(): when register is REG_SFR then
10590 set address to rIdx,
10591 pic16_allocProcessorRegister(): marks register wasUsed=0
10592 pic16_writeUsedRegs(): added a call to assign processor
10593 registers via pic16_assignFixedRegisters
10595 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10597 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10598 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10599 variables in unused register banks. Also the SSEG is placed
10600 wherever there is enough space for it, and IDATA can be anywhere
10601 in internal RAM. For now compile using -Wl-Y[stack_size].
10602 The mem file is different for this option as well, since it
10603 makes no sense of talking about DSEG lenght.
10605 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10607 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10608 in certain cases, e.g. when ROM assignment, patch provided
10609 from Albert den Haan.
10611 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10759 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10761 * src/SDCCicode.c (geniCodeAdd),
10762 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
10763 with valFromType if type might be a pointer and host is big endian).
10764 * src/SDCCast.c (decorateType): unary plus compatible with all arithmetic
10765 types, not just integer types.
10766 * src/SDCCsymt.c (addSymChain): clarified error message when symbol is
10767 multiply defined with mismatching "at" address.
10769 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10850 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10852 * src/SDCCast.c (decorateType): disabled a transformation I added in
10853 revision 1.188 (access to fields of a structure at an absolute address);
10854 it breaks with bitfields, extern declarations, and gcse analysis.
10855 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10856 could be assigned through a pointer, so don't complain.
10857 * src/SDCCast.c (astErrors),
10859 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
10861 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

11598 and JUMPTABLE iCodes properly now (worked by accident before)
11599 * src/mcs51/gen.c (leftRightUseAcc),
11600 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11601 iCode properly now. Use getSize instead of nRegs since a & b
11602 aren't part of the nRegs tally.
11604 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11606 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11616 copied from genNearPointerSet()
11617 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11618 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11619 If they pop r0/r1 they must be called in the opposite order than aopOp().
11620 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11621 (resp. --stack-auto), prepared for --xstack
11623 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11632 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11634 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11635 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11636 type for bits was changed. It resulted in bit variables becoming
11637 global, which is not permitted in PIC 14 assembly output.
11639 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11641 * doc/sdccman.lyx: various additions and updates. Rearranged sections

11654 A few small changes that speed up the peephole optimizer.
11658 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11660 Try to make the peephole optimizer smarter by maintaining
11661 an association between the assembly source code and the
11662 iCodes that originated them. Put this information to use
11663 with a new peephole rule condition "notVolatile" so that
11664 the rules can be aggressive yet still safe.
11669 * src/mcs51/peeph.def
11671 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11675 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11676 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11677 if the left or right operand symbols have the accuse flag set.
11679 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11681 Changed the type of the result of the ! (NOT) operator to char;
11682 previously it returned the same type as the source. This allows
11683 us to eliminate all the genFloatNot functions (all of its target
11684 implementations were very buggy) since !float can use the same
11687 * src/SDCCicode.c (ast2iCode): ! returns char

11696 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11697 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11698 during interrupts. Ensure WSAVE is located at a shared bank address.
11699 2. Fixed page selection in some places
11700 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11701 the registers name strings.
11702 4. Fixed "signed / unsigned compare" compiler warnings.
11703 5. The PIC port manages its own allocation of the general purpose
11704 registers, but makes no attempt to reuse them. As a result when
11705 compiling it soon runs out of general purpose registers. Some
11706 additional code was added to the files pcode.c and device.c to walk
11707 through the function call tree and rename the registers so that they
11717 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11718 genPlus() & genMinus() when the result is the same as left or right

11724 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11726 Made bitfield a distinct type from bit so that bitfields
11727 convert as per ANSI C and bits retain their traditional
11728 boolean style behaviour. Implemented bitfield support in
11736 * src/ds390/gen.c: bit v bitfield split
11737 * src/z80/gen.c: New support for bitfields
11738 * support/regression/tests/bitfields.c: reenabled z80,
11741 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11743 Rules 246.x, 247.x relate to bitfields, the others speed up
11744 access to xdata mapped I/O devices.
11746 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11748 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11750 Cleaned up genPackBits and genUnpackBits and added two helper
11751 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11752 for literal assignments in genPackBits (thanks to Frieder for
11758 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11760 Fixed bug #748310 (pointer to function type mishandled when the
11761 function name is omitted). Also fixed a SIGSEGV when a function
11762 attribute (reentrant, etc) is used on a non-function or on a
11763 function but misplaced before the parameter list.
11765 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11767 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11768 * support/Util/SDCCerr.h,

11790 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11792 Made the constant following the "interrupt" keyword optional. If
11793 omitted, the function will not automatically be given an entry
11794 in the interrupt vector table (similar to #pragma NOIV, but
11795 less syntacticly kludgy). The interrupt number is also now
11796 range checked. Also fixed a bug in the high order bit example

11815 be re-activated by defining REDUCE_LITERALS)
11816 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11817 unsigned, but are signed by default

12326 added if/endif conditional macros to remove options help
12327 messages from optionsTable when a port is not configured, added
12328 support for the PIc16 port in the ports table, when executing
12329 the compiler with no port specified on command line, a default
12330 port is selected with the new macro DEFAULT_PORT which is
12331 defined in port.h, in setDefaultOptions() linkOptions is removed
12332 from initialization assignment, since now it is a set,
12333 parseCmdLine uses setParseWithComma for linkOptions, in
12334 linkEdit() linkOptions are accessed with new function indexSet()
12335 which returns the i'th item of a set variable. See SDCCset.c, in
12336 linkEdit() when calling buildCmdLine(), added linkOptions as
12337 last argument. Now users can pass arguments to gplink via the
12338 -Wl option, main() uses pic16glue() to glue up pic16 programs

12351 * src/pic16/main.c: __config directives are commented out to stop
12352 gpasm complaining and test the linkage with gplink, _linkCmd and
12353 _asmCmd changed to be more gplink and gpasm friendly
12354 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12355 produced an error when parsed, peep rule 12 is added to utilize
12356 movff, but it is commented out since the pCode does not support
12357 yet a command with 2 address arguments
12359 2003-05-18 <johan AT balder>
12361 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13409 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13410 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

13416 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13417 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13419 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13420 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13422 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13424 * in /sdcc/as/mcs51/ changed these files in order to create an
13425 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13426 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13427 following files to include the previous two files: aslink.dsp,
13428 Makefile.aslink, Makefile.bcc, and Makefile.in.
13430 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13431 .adb instead of .cdb
13433 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13435 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13436 value from option --iram-size.
13438 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13440 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13443 2002-09-18 <wiml AT hhhh.org>
13445 * SDCClrange.h: exposed setFromRange() and setToRange()
13446 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13447 packRegsForAccUse() (bug 542397)
13448 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13449 multiple times and emitting the fetch operations more than once
13450 added aopGetUsesAcc() function to allow binary operators to
13451 fetch their operands in the correct order; made genMinus() emit
13452 compact code for X = LITERAL - Y
13454 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13455 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13456 sprintf() in line 1267.
13458 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13459 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13462 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13463 Changes to aslink (All the changes are marked with 'JCF'):
13465 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13468 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13469 area BSEG. Also moves, if possible, the DATA area down into the internal
13470 ram so more space is available.
13472 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13475 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13476 not bytes. Function summary() which creates a memory usage summary
13477 file with extension .mem. Reports of overlaping stack and small stack
13478 size. If the space for the stack is less than 16 bytes aslink trows a
13481 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13482 the 8051. Option 'y' for memory summary output file.
13484 Changes to sdcc (All the changes are marked with 'JCF'):
13486 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13488 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13489 overlaying area for it (uses RegBankUsed[4]).
13491 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13492 bank zero as used by default. By default aslink locates the stack
13493 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13494 the creation of the .mem file. Delegates the allocation of data area
13495 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13496 the begining of the stack area to aslink.
13498 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13499 glue() in SDCCglue.c creates an area for it.
13501 2002-09-03 Borut Razem <borut.razem AT siol.net>
13502 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13503 sdcc/src/pic/glue.c:
13504 introduced atexit() handler for teporay files removal in case of
13505 errors, assertions, ...
13507 2002-08-29 Borut Razem <borut.razem AT siol.net>
13508 * sdcc/support/cpp2/auto-host_vc_in.h:
13509 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13510 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13511 Maybe there is a similar problem with BORLANDC? It should be checked!
13513 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13514 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13515 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13516 was not executed, and the compiler (cl) launched a warning:
13517 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13519 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13520 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13522 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13523 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13525 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13526 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13527 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13528 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13529 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13530 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13531 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13532 - added Release configuration in VS projects
13533 - review of compiler an linker options
13534 - VC .exe files are generated in bin_vc directory, not to interfere
13535 with binaries generated from other projects (cygwin, mingw, bcc ...)
13537 * sdcc/src/yacc.dsp: added
13539 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13540 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13541 and insert the version number definitions from .version
13543 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13545 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13546 added - genarate auto-host.h using auto-host_vc_in.h as template
13549 removed from CVS, generated automatically
13551 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13552 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13554 2002-08-11 Borut Razem <borut.razem AT siol.net>
13555 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13557 2002-08-10 Borut Razem <borut.razem AT siol.net>
13558 * src/SDCCmain.c (main):
13559 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13560 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13561 The consequence was that some temporary files were not removed.
13564 unification of code in functions tempfilename() and tempfile():
13565 function tempnam() is defined in Visual Studio 6.0 and .NET
13567 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13569 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13570 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13571 - removed compiler command line option /WX: Treats all warnings as errors
13572 - update a list of source files, included into the project
13574 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13575 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13576 changed project type to Generic Project so that can be correcly converted to VS.NET project
13578 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13580 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13582 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13584 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13585 added return 0 statements after assert() to make compiler happy
13587 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13588 added newline in the def file to keep MSC compiler satisfied
13590 * sdcc/src/z80/gen.c:
13591 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13592 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13593 - solved MSC error in function aopDump()
13595 * sdcc_vc.h: define PREFIX as "\\sdcc"
13597 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13598 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13600 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13601 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13602 - Rewrote the register banking algorithm.
13603 - Added pCode live-range analysis to registers (for now, only non-used and
13604 singly-used registers optimized away)
13606 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13608 * 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.
13610 2002-05-10 Scott Dattalo <scott AT dattalo.com>

13623 2002-04-15 Michael Hope <michaelh AT vroom>
13625 * device/lib/z80/printf.c (sprintf): Added.
13627 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13629 * src/z80/peeph.def: Added transpose redundent load rule.
13631 * src/z80/main.c: Added force callee saves for jaune.
13633 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13635 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13637 2002-03-28 Johan Knol <johan AT balder>
13639 * src/SDCCval.c: fixed bug #532436
13641 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13643 Added "char *Processor" field to the port structure.
13646 Added -p option. Allows port dependent processor to be specified.
13649 Initialized the new field char *Processor field to NULL in all ports
