801 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
803 Enabled VPATH feature: changed nearly all Makefiles (149 files).
804 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
806 One basic decision: e.g. src/clean.mk includes further files. In order
807 to make this work there are two solutions:
808 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
809 run configure on them. This way they can use
810 'include $(srcdir)/port-clean.mk'
811 - always include clean.mk by the Makefile at the same level. To avoid
812 that `make clean` tries to include and build Makefile.dep the
813 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
814 implemented, because now even `make uninstall` doesn't create
815 Makefile.in. clean.mk could be eliminated by pasting it in
818 * debugger/mcs51/Makefile.in: build own objects from library sources
819 (SLIB, SDCC) in current directory
821 * configure, configure.in: renamed --disable-device-lib-build in
822 --disable-device-lib; added --enable-doc, the required tools are
823 searched by configure; added result message; the toolchain for the
824 belonging ports are now only built, if the port is enabled.
826 * support/regression/*: all output is written in directory gen, because
827 the fwk and ports directories don't livet in the build tree using vpath
829 * doc/sdccman.lyx: renamed --disable-device-lib-build to
830 --disable-device-lib, added --enable-doc, added section VPATH
832 * sim/ucsim/configure.in,
833 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
834 z80 are enabled by default
836 2006-04-24 Raphael Neider <rneider AT web.de>
838 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
839 to config word, "pic14_"-prefixed some extern functions
840 (pic14_emitConfigWord): emit __config directive(s) if assignment to
841 config word has been found
842 * src/pic/device.h: added prototypes
843 * src/pic/pcode.c: added "pic14_"-prefix where needed
844 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
846 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
848 (pic14emitRegularMap): ignore config words,
849 (pic14createInterruptVect): moved generating __config directives away
850 (picglue): have __config directives emitted

860 fixes #1469504 and #1474602,
861 (pCodeRegOptimizeRegUsage): fixed typo in comment
863 2006-04-24 Borut Razem <borut.razem AT siol.net>
865 * device/examples/main8051.c: deleted - it was removed from CVS
866 24.mar.2000 and after that modified 18.feb.2001, so it reappered

868 * src/SDCCalloc.h: deleted - it was removed from CVS

1084 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1086 * src/mcs51/gen.c (genCall): fixed bug 1457608
1088 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1107 implemented patch 1120823 Thanks to Willy De la Court (normal
1108 interrupts need an interrupt number now if they are made critical),
1109 and enabled nesting of critical functions though not for gbz80
1110 (genCritical, genEndCritical): added functions
1111 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1112 * src/z80/mappings.i: added "ei" to all mappings

1124 the left operand is shorter than the result (c* = lit-c* + int),
1126 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1129 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1131 * src/.version: increased version number to 2.5.5
1132 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1133 linking is done manually in pic16 port's _linkEdit,
1134 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1135 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1136 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1137 allocate asmop as AOP_ACC,
1138 (aopForRemat): added parameter 'bool result' in function declaration,
1139 (pic16_aopGet): return AOP_ACC when accessing WREG,
1140 (pic16_popGetTempReg): minor modification,

1151 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1152 call to allocReg, not by manually allocating a new one,
1153 (pic16_assignRegisters): now before going through the register
1154 allocating functions mark all registers as free. This eliminates some
1155 side effects resulting from peephole parser done earlier in the backbone
1157 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1215 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1216 which dumps before the function entry point a data byte which represents
1217 the number of the local variables used by the specified function, added
1218 'xinst' for initial support for Extended Instruction Support,
1219 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1220 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1221 port->fun_prefix anymore (may change later),
1222 (genFunction, genEndFunction): do not store/restore local registers for
1223 _main (this should take care the --main-return command line option in
1225 (genOr): removed some legacy pic-port instructions,
1226 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1227 performing operations with SFR's causes data to be written more than
1228 once to each SFR. Perhaps SFRs should be handled in special cases...
1229 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1231 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1232 into account for stack starting position,
1233 (struct OPTIONS pic16_optionsTable): added command line argument
1234 --extended or -y for Extended Instruction Support,
1235 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1236 (deassignLRs): *** perhaps the most important change, old 'for' code
1237 (commented out for reference), didn't account for some registers which
1238 were left marked 'not free' after a pointer operation. The change
1239 reduces register usage a lot in some cases
1241 2006-03-04 Borut Razem <borut.razem AT siol.net>

3508 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3510 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3512 * src/SDCCglobal.h (struct options),
3514 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3515 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3516 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3517 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3518 always available in leading double underscore form. The C99 support is
3519 mostly missing, but it's a start.
3520 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3521 reserved identifier "__data".
3523 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3599 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3601 * device/lib/printf_large.c: removed inline assembly for portability and
3602 readability. Use printf_fast if speed or size are more important.
3603 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3604 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3606 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3608 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3609 prevent compiler warning
3611 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3613 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3614 moved to level 0 and declared as static. Also they are explicit
3615 placed in access bank. This was necessery because some times they
3616 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3617 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3618 optimizations. Currently only compare to unsigned char is implemented,
3619 * src/pic16/gen.c: added fReturnIdx array,
3620 * (struct resolvedIfx) is moved to gen.h and made public,
3621 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3622 * (aopForSym): added an optimization to directly store in stack of
3623 the operand of a SEND iCode,
3624 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3625 but as registers instead (AOP_REG) using the fReturnIdx array,
3626 * (pic16_freeAsmop): remove the freed register from the
3627 _G.sregsAlloc field,
3628 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3629 a compare of 'WREG',
3630 * (pic16_popGetTempRegCond): changed function prototype, now
3631 function takes also a bitVector argument v which holds the current
3632 set of registers that are allocated for stack access by aopForSym,
3633 registers allocated in aopForSym for accessing stack symbols are not
3634 any more part of the functions usedRegs field,
3635 * (genCall): some times aopOp is called for a stack variable to be
3636 send, aopForSym might perform the push, if this is true make sure
3637 that genCall doesn't push the variable twice by testing _G.resDirect,
3638 * (genFunction): changed testing for unspecified interrupt number
3639 from 256 to INTNO_UNSPEC,
3640 * modified selection scheme of frame pointer generation. Previously
3641 if function did use local registers a frame pointer was generated,
3642 now a frame pointer is generated only if function has arguments
3643 (that need PLUSW2 register access), or has stack arguments, or the
3644 compiler is not instructed to omit the frame pointer,
3645 * (genEndFunction): before restoring local registers that were saved
3646 in the function preamble, also restore the registers that *might*
3647 have been allocated for stack access,
3648 * (genRet): removed some old comments,
3649 * (genCmp, the active (RN's) version): added a call to the
3650 pic16_genCmp_special function to perform the compare with a more
3651 robust and optimized way,
3652 * (genInline): a feature has been added in inline code generation,
3653 which allows a wildcard variable substitution when writing inline
3654 assembly. Code is incomplete and experimental therefore undocumented,
3655 * (genCast): changed order of aopOp for result and right to allow
3656 aopForSym to directly load the result if possible,
3657 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3658 perform an optimized compare on some selected special occasions,
3659 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3660 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3661 generate an IVT any more,
3662 * src/pic16/main.c (pic16_optionsTable): added command line option
3664 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3665 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3667 * src/pic16/NOTES: Raphael Neider added in list of active developers
3668 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3669 jumptable_end to prevent bug #,
3670 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3671 inCond and outCond fields,
3672 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3673 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3674 turn off register spilling,
3675 * (packRegsForOneUse): synced with other ports' versions although it
3676 is not used currently,
3677 * (pic16_packRegisters): added an optimization while reading
3678 structure bitfields, some registers may be saved (malloc code is
3679 decreased by 80 bytes)
3681 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3683 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3684 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3685 this can be optimized more?
3687 2005-03-10 Raphael Neider <rneider AT web.de>
3689 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3690 genNearPointerGet): (hopefully) fixed access to bitfields via
3691 pointers (p->bitN = x; and x = p->bitN; failed)
3693 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3695 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3870 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3871 (sizeof(sectNames) changed to sizeof(sectName))
3872 Both patches fix segfaults under MinGW.

3879 of (byte sized) temporaries (assign them to WREG for now)
3880 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3881 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3882 this might fix SIGSEGVs on MinGW...
3883 * src/SDCCopt.c (killDeadCode): restored original behaviour
3884 (volatile operands might get thrown away though)
3886 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3888 * src/pic16/gen.c: fixed bug #1106975,

4350 * src/pic16/genarith.c,
4353 * src/pic16/pcode.c: applied patches #1068154 and #1070213
4355 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4357 Large cummulative patch for pic16 port.
4358 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4359 to call when a stack overflow occurs,
4360 * (malloc.h): added CVS Id tag,
4361 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4363 * added libc directory. The current version of LibC contains string
4364 functions, ctype functions and macros and some functions of the
4365 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4366 be extensively tested in the future. Standard disclaimer here.
4367 Library is not automatically build yet. But one can build it by
4368 invoking 'make' inside the libc directory.
4369 * added ADC library under libio. Preliminary version yet.
4371 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4372 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4373 aopForRemat() now and not by pic16_aopOp(),
4374 * (pic16_popGetTempReg): removed warning messgae when allocating
4375 temporary registers, its a buggy feature and will be removed,
4376 * (pic16_popGet): set register instance field in AOP_CRY,
4377 * (pic16_outBitC): fixed for results in size greater than 1,
4378 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4379 * (pic16_storeForReturn): optimized return of 0,
4380 * (genCmp): experimental code for new genCmp which uses PIC18's
4381 special compare&skip instructions. Initial tests fail some times
4382 with variables grater than 1 byte in size, so new code is disabled,
4383 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4385 * (genCast): began a fix to optimize the casting of a bit to another
4386 bit, now assigning a bitfield to another bitfield will fail, sorry,
4387 * src/pic16/main.c: disabled the use of lr-support feature,
4388 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4389 * added some function prototypes, added function _debugf prototype,
4390 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4391 bits with offset (case PO_GPR_BIT),
4392 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4394 * (isBankInstruction): modified to return 0 for no banking instruction,
4395 and 1 for banking instruction,
4396 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4397 caused stop processing pCodes after a inline assembly block,
4398 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4399 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4400 registers when it shouldn't,
4401 * src/pic16/ralloc.c (allocReg): add preliminary support for
4402 supporting a limited set of temporary registers,
4404 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4406 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4407 genDataPointerSet): ensure assignments always copy in MSB to LSB
4409 (loadRegFromAop): recognize CLRH optimization,
4410 (genFunction): optimize RECEIVE iCodes in reentrant functions
4412 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4414 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4415 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4417 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4423 * device/lib/_gptrget.c (_gptrget),
4424 * device/lib/_gptrgetc.c (_gptrgetc),
4425 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4426 instead of sjmp to ret
4427 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4428 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

7412 loaded with the linker search paths (-L arguments) and the libraries
7413 to be linked with the current source (-l arguments). Changes
7414 currently will affect only the pic16 port.
7415 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7416 include path the port specific paths and port specific libraries,

7437 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7438 when generating output files to configure the pic16 library,
7439 but now I've commented it out, since gputils aren't installed in the
7440 SF compile farm, so library won't compile
7442 * device/lib/Makefile.in (version 1.56): initially I've added in
7443 target 'all' the prerequestive 'model-pic16' so it compiled the
7444 pic16 library, but now I've commented it out for the same reasons
7446 * added targets 'model-pic16' and 'objects-pic16' to compile the
7448 * added target 'port-specific-objects-pic16' to handle the
7449 generated libraries and copy them into the build/ directory
7450 * added target 'clean-intermediate-pic16' to clean intermediate
7451 files into pic16 directory
7452 * in target 'installdirs' added line to create directory pic16 in
7453 the installation path
7455 * device/include/Makefile.in (version 1.11): in target 'install'
7456 added lines to copy all header files to installation path,
7457 * in target 'installdirs' added line create directory for pic16
7458 headers in the installation path

7473 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7474 option so that it actually works. Made it specific to the z80, since
7475 the gbz80 doesn't have these kinds of I/O ports.
7477 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7479 * device/include/z180.h,

7486 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7487 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7488 portmode; added deprecation warning for bank= and protmode= forms.
7489 Also, guard against buffer overflow.
7490 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7492 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7494 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

7497 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7499 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7501 Mainly changes to support compilation of the device libraries
7502 * src/pic16/device.c: stack is allocated via symbol and not
7503 via literal number. The symbol is placed in the corresponding
7504 position of the data ram
7505 * (pic16_dump_section): relocatable and absolute uninitialized
7506 data are now emitted in sorted order to reduce section naming,
7507 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7508 weren't marked as being in the access bank,
7510 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7512 Added portion of GNU PIC Library under the directory
7513 device/include/pic16 and device/lib/pic16. These files
7514 contain the declarations of SFRs for the PIC18Fxx2 devices.
7515 The directory is initialized via configure from toplevel.
7517 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7519 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7520 the spilllocations to be compared correctly

7544 * doc/sdccman.lyx: Moved and added some sections, small changes
7545 all over. Telling LaTeX to be less strict with word spacing
7546 to better keep the right margin. Changed some notes about
7547 maintainance of the ports in section 3.2.1 - is it OK like this?
7549 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7586 UPPER for immediate operands,
7587 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7589 * src/pic16/peeph.def: all peepholes with movff are commented out,
7590 because there is a problem in the pcode peep optimizer,
7591 * src/pic16/ralloc.c: the register allocator can now reuse local
7592 function symbols for another function. This saves register usage.
7593 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7595 Added file src/pic16/NOTES with information about program writing on
7596 the current port version.

7651 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7652 * src/pic/glue.c: added variable udata_section_name to
7653 override default uninitialized data segment definition for

7701 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7703 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7704 (default behaviour).
7706 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7708 A python script to validate compiler diagnostic messages. It can be
7709 used to verify that sdcc complains about bad c source code and
7710 gives a good location of the error.
7711 * support/valdiag/Makefile,
7712 * support/valdiag/valdiag.py,
7713 * support/valdiag/tests/*

7730 Bug reported from Jesus Calvino-Fraga
7732 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7734 * sdcc.spec: updated
7735 * device/include/Makefile.in: don't install CVS directories
7736 * device/lib/Makefile.in: added removal of CVS directories after install
7737 * doc/Makefile: fixed install, added local_icons
7738 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7739 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7740 * src/ds390/gen.c (genRightShift): fixed bug #870788
7741 * src/SDCCast.c (decorateType): fixed bug #870781
7743 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7745 PIC16 port related changes:
7746 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7747 added variable stackPos,
7749 * gen.c: genCall, assignResultValue: added support for
7750 pushing/retrieving function parameters to/from stack,
7751 genFunction,genEndFunction: setup stack frame for the
7753 genAddrOf: will be changed according to bug 863624
7755 * added files genutils.c and genutils.h which contain gen*
7756 debugged and optimised functions extracted from gen.c
7758 * glue.c: added variable 'externs' which holds extern symbols,
7759 pic16emitRegularMap: is modified to properly handle relocatable
7760 symbols under the new scheme,
7761 pic16createInterruptVect: is modified
7762 pic16printPublics: is modified to emit 'global' assembler directives,
7763 added pic16_printExterns to print extern symbols,
7764 pic16glue: initializes stack/frame pointer in the beginning of
7765 the assembly output. Temporary hack, will be corrected later,
7766 because gplink yet does not support stack and SDCC does not
7767 yet support a type of crt0.o object to create the final binary.
7769 * Removed many lines that contain 8051 legacy code.
7770 * The code is finally placed under a 'code' directive.
7771 * Added port specific options.
7773 * _process_pragma: simplified since now we do not need *special*
7774 include file to define SFR registers. But a separate header
7775 will be needed. This will be developed later.
7776 * _pic16_parseOptions: added, parses port specific options:
7777 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7778 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7779 --preplace-udata-with=
7781 * _pic16_setDefaultOptions: modified to initialize section names,
7782 but hack is temporarly out of order since it needs improvement.
7783 * _pic16_genAssemblerPreamble: configuration words are emitted by
7784 their address instead of their name. This part is incomplete and
7785 supports only the 18Fxx2 devices. Other devices will emit an error
7786 during assembly since they do not contain the same set of config
7788 * _pic16_genIVT: is modified,
7790 * pcode.c: added definitions for some hardware registers that are needed
7792 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7793 All PCI entries are updated. Now LFSR is supported.
7794 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7795 * added pic16_newpCodeOpLit2 to support instructions with
7796 two literal arguments
7797 * pic16_pCode2str: corrected code that emits assembler instructions
7798 with two literal operands and those that have an access bit modifier
7799 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7800 this fixes a bug which caused some labels to be lost, when an
7801 assembler directive was added, i.e. banksel,
7802 * pic16_FixRegisterBanking: improved logic that causes the insertion
7804 * InlineFunction: functions that are called once, are not any more
7805 inlined. This can be a port option in the future,
7807 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7809 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7810 hold the corresponding uninitialized symbols,
7811 * pic16_allocProcessorRegister: registers have explicit marked the
7813 * pic16_allocInternalRegister: registers are explicit marked as
7815 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7816 processing list, so bit registers were lost,
7819 * ralloc.h: added field 'accessBank' and original symbol operand
7820 in register definition,
7821 * removed the field isMapped from register definition,
7823 ** Several functions have been removed from various sources:
7824 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7825 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7826 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7827 pic16_assignRelocatableRegisters
7829 ** others have been introduced:
7830 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7831 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7833 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7835 * support/scripts/inc2h.pl: changed definition of BIT_AT
7836 to emit 'sbit at' instead of 'bit at'. This was a request.
7838 PIC16 port related preliminary changes:
7839 * gen.c: prefixed function popRegFromString with
7840 pic16_ and all references to it corrected
7841 * pcode.c: all pic16_pc_* hardware registers prefixed
7842 with underscore (_),
7843 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7844 * ralloc.c: newReg(): when register is REG_SFR then
7845 set address to rIdx,
7846 pic16_allocProcessorRegister(): marks register wasUsed=0
7847 pic16_writeUsedRegs(): added a call to assign processor
7848 registers via pic16_assignFixedRegisters
7850 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7852 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7853 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7854 variables in unused register banks. Also the SSEG is placed
7855 wherever there is enough space for it, and IDATA can be anywhere
7856 in internal RAM. For now compile using -Wl-Y[stack_size].
7857 The mem file is different for this option as well, since it
7858 makes no sense of talking about DSEG lenght.
7860 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7862 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7863 in certain cases, e.g. when ROM assignment, patch provided
7864 from Albert den Haan.
7866 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8419 not occur if the control variable is involved with a
8420 relational operator.

8913 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8915 Try to make the peephole optimizer smarter by maintaining
8916 an association between the assembly source code and the
8917 iCodes that originated them. Put this information to use
8918 with a new peephole rule condition "notVolatile" so that
8919 the rules can be aggressive yet still safe.

8932 if the left or right operand symbols have the accuse flag set.
8934 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8936 Changed the type of the result of the ! (NOT) operator to char;
8937 previously it returned the same type as the source. This allows
8938 us to eliminate all the genFloatNot functions (all of its target
8939 implementations were very buggy) since !float can use the same
8942 * src/SDCCicode.c (ast2iCode): ! returns char

8951 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8952 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8953 during interrupts. Ensure WSAVE is located at a shared bank address.
8954 2. Fixed page selection in some places
8955 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8956 the registers name strings.
8957 4. Fixed "signed / unsigned compare" compiler warnings.
8958 5. The PIC port manages its own allocation of the general purpose
8959 registers, but makes no attempt to reuse them. As a result when
8960 compiling it soon runs out of general purpose registers. Some
8961 additional code was added to the files pcode.c and device.c to walk
8962 through the function call tree and rename the registers so that they
8972 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8973 genPlus() & genMinus() when the result is the same as left or right

8979 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8981 Made bitfield a distinct type from bit so that bitfields
8982 convert as per ANSI C and bits retain their traditional
8983 boolean style behaviour. Implemented bitfield support in
8991 * src/ds390/gen.c: bit v bitfield split
8992 * src/z80/gen.c: New support for bitfields
8993 * support/regression/tests/bitfields.c: reenabled z80,
8996 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8998 Rules 246.x, 247.x relate to bitfields, the others speed up
8999 access to xdata mapped I/O devices.
9001 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9003 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9005 Cleaned up genPackBits and genUnpackBits and added two helper
9006 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9007 for literal assignments in genPackBits (thanks to Frieder for
9013 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9015 Fixed bug #748310 (pointer to function type mishandled when the
9016 function name is omitted). Also fixed a SIGSEGV when a function
9017 attribute (reentrant, etc) is used on a non-function or on a
9018 function but misplaced before the parameter list.

9045 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9047 Made the constant following the "interrupt" keyword optional. If
9048 omitted, the function will not automatically be given an entry
9049 in the interrupt vector table (similar to #pragma NOIV, but
9050 less syntacticly kludgy). The interrupt number is also now
9051 range checked. Also fixed a bug in the high order bit example

9527 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9528 the regression tests I'm not brave enough to enable 245.b, 245.c
9529 * doc/sdccman.lyx: added latex preamble for hyperref package.
9530 Using pdflatex this will give you a hyperlinked pdf file with
9531 bookmarks. (prepend '%' before /usepackage if this breaks something)

9572 it can be defined with CFLAGS when running configure
9573 * src/SDCCmain.c: fixed compiling + linking with object files
9575 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9578 added --disable-pic16-port
9579 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9580 * src/SDCCmain.c: linkOptions is changed to set *,
9581 added if/endif conditional macros to remove options help
9582 messages from optionsTable when a port is not configured, added
9583 support for the PIc16 port in the ports table, when executing
9584 the compiler with no port specified on command line, a default
9585 port is selected with the new macro DEFAULT_PORT which is
9586 defined in port.h, in setDefaultOptions() linkOptions is removed
9587 from initialization assignment, since now it is a set,
9588 parseCmdLine uses setParseWithComma for linkOptions, in
9589 linkEdit() linkOptions are accessed with new function indexSet()
9590 which returns the i'th item of a set variable. See SDCCset.c, in
9591 linkEdit() when calling buildCmdLine(), added linkOptions as
9592 last argument. Now users can pass arguments to gplink via the
9593 -Wl option, main() uses pic16glue() to glue up pic16 programs

9605 * src/pic16/glue.c: commented out some error producing lines
9606 * src/pic16/main.c: __config directives are commented out to stop
9607 gpasm complaining and test the linkage with gplink, _linkCmd and
9608 _asmCmd changed to be more gplink and gpasm friendly
9609 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9610 produced an error when parsed, peep rule 12 is added to utilize
9611 movff, but it is commented out since the pCode does not support
9612 yet a command with 2 address arguments
9614 2003-05-18 <johan AT balder>
9616 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9641 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9643 2003-05-11 Borut Razem <borut.razem AT siol.net>
9645 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9646 the path of bin directory, so that PATH is the only env. variable, which has to be set
9647 in case of standard installation.
9648 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10677 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10679 * in \sdcc\as\mcs51\ changed these files in order to create an
10680 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10681 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10682 following files to include the previous two files: aslink.dsp,
10683 Makefile.aslink, Makefile.bcc, and Makefile.in.
10685 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10686 .adb instead of .cdb
10688 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10690 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10691 value from option --iram-size.
10693 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10695 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10698 2002-09-18 <wiml AT hhhh.org>
10700 * SDCClrange.h: exposed setFromRange() and setToRange()
10701 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10702 packRegsForAccUse() (bug 542397)
10703 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10704 multiple times and emitting the fetch operations more than once
10705 added aopGetUsesAcc() function to allow binary operators to
10706 fetch their operands in the correct order; made genMinus() emit
10707 compact code for X = LITERAL - Y
10709 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10710 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10711 sprintf() in line 1267.
10713 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10714 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10717 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10718 Changes to aslink (All the changes are marked with 'JCF'):
10720 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10723 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10724 area BSEG. Also moves, if possible, the DATA area down into the internal
10725 ram so more space is available.
10727 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10730 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10731 not bytes. Function summary() which creates a memory usage summary
10732 file with extension .mem. Reports of overlaping stack and small stack
10733 size. If the space for the stack is less than 16 bytes aslink trows a
10736 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10737 the 8051. Option 'y' for memory summary output file.
10739 Changes to sdcc (All the changes are marked with 'JCF'):
10741 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10743 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10744 overlaying area for it (uses RegBankUsed[4]).
10746 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10747 bank zero as used by default. By default aslink locates the stack
10748 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10749 the creation of the .mem file. Delegates the allocation of data area
10750 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10751 the begining of the stack area to aslink.
10753 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10754 glue() in SDCCglue.c creates an area for it.
10756 2002-09-03 Borut Razem <borut.razem AT siol.net>
10757 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10758 sdcc/src/pic/glue.c:
10759 introduced atexit() handler for teporay files removal in case of
10760 errors, assertions, ...
10762 2002-08-29 Borut Razem <borut.razem AT siol.net>
10763 * sdcc/support/cpp2/auto-host_vc_in.h:
10764 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10765 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10766 Maybe there is a similar problem with BORLANDC? It should be checked!
10768 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10769 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10770 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10771 was not executed, and the compiler (cl) launched a warning:
10772 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10774 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10775 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10787 - added Release configuration in VS projects
10788 - review of compiler an linker options
10789 - VC .exe files are generated in bin_vc directory, not to interfere
10790 with binaries generated from other projects (cygwin, mingw, bcc ...)
10792 * sdcc/src/yacc.dsp: added
10794 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10795 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10796 and insert the version number definitions from .version
10798 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10800 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10807 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10809 2002-08-11 Borut Razem <borut.razem AT siol.net>
10810 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10812 2002-08-10 Borut Razem <borut.razem AT siol.net>
10813 * src/SDCCmain.c (main):
10814 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10815 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10816 The consequence was that some temporary files were not removed.
10819 unification of code in functions tempfilename() and tempfile():
10820 function tempnam() is defined in Visual Studio 6.0 and .NET
10822 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10824 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10825 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10826 - removed compiler command line option /WX: Treats all warnings as errors
10827 - update a list of source files, included into the project
10829 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10830 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10831 changed project type to Generic Project so that can be correcly converted to VS.NET project
10833 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10835 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10839 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10840 added return 0 statements after assert() to make compiler happy
10842 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10843 added newline in the def file to keep MSC compiler satisfied
10845 * sdcc/src/z80/gen.c:
10846 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10847 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10848 - solved MSC error in function aopDump()
10850 * sdcc_vc.h: define PREFIX as "\\sdcc"
10852 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11027 * sdcc/src/SDCCloop.c:
11028 Previous fix was not good. basic blocks that have "break" or "return" are
11029 not really partof a loop , but live ranges used in these blocks should
