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

853 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
855 (pic14emitRegularMap): ignore config words,
856 (pic14createInterruptVect): moved generating __config directives away

867 fixes #1469504 and #1474602,
868 (pCodeRegOptimizeRegUsage): fixed typo in comment
870 2006-04-24 Borut Razem <borut.razem AT siol.net>
872 * device/examples/main8051.c: deleted - it was removed from CVS

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

1114 implemented patch 1120823 Thanks to Willy De la Court (normal
1115 interrupts need an interrupt number now if they are made critical),
1116 and enabled nesting of critical functions though not for gbz80
1117 (genCritical, genEndCritical): added functions
1118 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1119 * src/z80/mappings.i: added "ei" to all mappings

1131 the left operand is shorter than the result (c* = lit-c* + int),
1133 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1136 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1138 * src/.version: increased version number to 2.5.5
1139 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1140 linking is done manually in pic16 port's _linkEdit,
1141 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1142 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1143 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1144 allocate asmop as AOP_ACC,
1145 (aopForRemat): added parameter 'bool result' in function declaration,
1146 (pic16_aopGet): return AOP_ACC when accessing WREG,
1147 (pic16_popGetTempReg): minor modification,

1158 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1159 call to allocReg, not by manually allocating a new one,
1160 (pic16_assignRegisters): now before going through the register
1161 allocating functions mark all registers as free. This eliminates some
1162 side effects resulting from peephole parser done earlier in the backbone
1164 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1222 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1223 which dumps before the function entry point a data byte which represents
1224 the number of the local variables used by the specified function, added
1225 'xinst' for initial support for Extended Instruction Support,
1226 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1227 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1228 port->fun_prefix anymore (may change later),
1229 (genFunction, genEndFunction): do not store/restore local registers for
1230 _main (this should take care the --main-return command line option in
1232 (genOr): removed some legacy pic-port instructions,
1233 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1234 performing operations with SFR's causes data to be written more than
1235 once to each SFR. Perhaps SFRs should be handled in special cases...
1236 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1238 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1239 into account for stack starting position,

1241 --extended or -y for Extended Instruction Support,
1242 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1243 (deassignLRs): *** perhaps the most important change, old 'for' code
1244 (commented out for reference), didn't account for some registers which
1245 were left marked 'not free' after a pointer operation. The change
1246 reduces register usage a lot in some cases
1248 2006-03-04 Borut Razem <borut.razem AT siol.net>

3515 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3517 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3518 * src/z80/main.c (_keywords[]),
3519 * src/SDCCglobal.h (struct options),
3521 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3522 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3523 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3524 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3525 always available in leading double underscore form. The C99 support is
3526 mostly missing, but it's a start.
3527 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3528 reserved identifier "__data".
3530 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3574 immedDom() returning wrong block; probably fixes bug #1160833)
3576 2005-03-20 Borut Razem <borut.razem AT siol.net>
3578 * support/scripts/inc2h.pl: WIN32 port

3582 * device/lib/makefile.in: added abs.c and labs.c
3584 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3586 * device/include/stdint.h: added
3587 * device/lib/abs.c: added

3606 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3608 * device/lib/printf_large.c: removed inline assembly for portability and
3609 readability. Use printf_fast if speed or size are more important.
3610 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3611 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3613 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3615 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3616 prevent compiler warning
3618 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3620 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3621 moved to level 0 and declared as static. Also they are explicit
3622 placed in access bank. This was necessery because some times they
3623 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3624 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3625 optimizations. Currently only compare to unsigned char is implemented,
3626 * src/pic16/gen.c: added fReturnIdx array,
3627 * (struct resolvedIfx) is moved to gen.h and made public,
3628 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3629 * (aopForSym): added an optimization to directly store in stack of
3630 the operand of a SEND iCode,
3631 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3632 but as registers instead (AOP_REG) using the fReturnIdx array,
3633 * (pic16_freeAsmop): remove the freed register from the
3634 _G.sregsAlloc field,
3635 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3636 a compare of 'WREG',
3637 * (pic16_popGetTempRegCond): changed function prototype, now
3638 function takes also a bitVector argument v which holds the current
3639 set of registers that are allocated for stack access by aopForSym,
3640 registers allocated in aopForSym for accessing stack symbols are not
3641 any more part of the functions usedRegs field,
3642 * (genCall): some times aopOp is called for a stack variable to be
3643 send, aopForSym might perform the push, if this is true make sure
3644 that genCall doesn't push the variable twice by testing _G.resDirect,
3645 * (genFunction): changed testing for unspecified interrupt number
3646 from 256 to INTNO_UNSPEC,
3647 * modified selection scheme of frame pointer generation. Previously
3648 if function did use local registers a frame pointer was generated,
3649 now a frame pointer is generated only if function has arguments
3650 (that need PLUSW2 register access), or has stack arguments, or the
3651 compiler is not instructed to omit the frame pointer,
3652 * (genEndFunction): before restoring local registers that were saved
3653 in the function preamble, also restore the registers that *might*
3654 have been allocated for stack access,
3655 * (genRet): removed some old comments,
3656 * (genCmp, the active (RN's) version): added a call to the
3657 pic16_genCmp_special function to perform the compare with a more
3658 robust and optimized way,
3659 * (genInline): a feature has been added in inline code generation,
3660 which allows a wildcard variable substitution when writing inline
3661 assembly. Code is incomplete and experimental therefore undocumented,
3662 * (genCast): changed order of aopOp for result and right to allow
3663 aopForSym to directly load the result if possible,
3664 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3665 perform an optimized compare on some selected special occasions,
3666 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3667 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3668 generate an IVT any more,
3669 * src/pic16/main.c (pic16_optionsTable): added command line option
3671 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3672 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3674 * src/pic16/NOTES: Raphael Neider added in list of active developers
3675 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3676 jumptable_end to prevent bug #,
3677 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3678 inCond and outCond fields,
3679 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3680 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3681 turn off register spilling,
3682 * (packRegsForOneUse): synced with other ports' versions although it
3683 is not used currently,
3684 * (pic16_packRegisters): added an optimization while reading
3685 structure bitfields, some registers may be saved (malloc code is
3686 decreased by 80 bytes)
3688 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3690 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3691 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3692 this can be optimized more?
3694 2005-03-10 Raphael Neider <rneider AT web.de>
3696 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3697 genNearPointerGet): (hopefully) fixed access to bitfields via
3698 pointers (p->bitN = x; and x = p->bitN; failed)
3700 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3743 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3744 to keep the correct label reference count when adding/removing references
3745 to labels. A peephole file using this is appended to patch #1144962.

3877 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3878 (sizeof(sectNames) changed to sizeof(sectName))
3879 Both patches fix segfaults under MinGW.

3885 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3886 of (byte sized) temporaries (assign them to WREG for now)
3887 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3888 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3889 this might fix SIGSEGVs on MinGW...
3890 * src/SDCCopt.c (killDeadCode): restored original behaviour
3891 (volatile operands might get thrown away though)
3893 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3895 * src/pic16/gen.c: fixed bug #1106975,

4334 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4335 Now 4 algorithms for mcs51 jumptable generation are used:
4336 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4337 addresses loaded pc-relative for up to 112 cases and stack-pushing
4338 target addresses loaded with offset from dptr for up to 256 cases.
4340 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4341 * src/mcs51/main.c: adapted constants for switch table generation
4342 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp
4344 2004-11-26 Maarten Brock <sourceforge.brock AT dse.nl>
4346 * device/lib/printf_large.c (_print_format): fixed bug 1073386
4347 * support/regression/tests/bug1057979.c: added test for bug 1073386
4349 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
4351 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
4354 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
4356 * src/pic16/device.h,
4357 * src/pic16/genarith.c,
4360 * src/pic16/pcode.c: applied patches #1068154 and #1070213
4362 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4364 Large cummulative patch for pic16 port.
4365 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4366 to call when a stack overflow occurs,
4367 * (malloc.h): added CVS Id tag,
4368 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4370 * added libc directory. The current version of LibC contains string
4371 functions, ctype functions and macros and some functions of the
4372 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4373 be extensively tested in the future. Standard disclaimer here.
4374 Library is not automatically build yet. But one can build it by
4375 invoking 'make' inside the libc directory.
4376 * added ADC library under libio. Preliminary version yet.
4378 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4379 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4380 aopForRemat() now and not by pic16_aopOp(),
4381 * (pic16_popGetTempReg): removed warning messgae when allocating
4382 temporary registers, its a buggy feature and will be removed,
4383 * (pic16_popGet): set register instance field in AOP_CRY,
4384 * (pic16_outBitC): fixed for results in size greater than 1,
4385 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4386 * (pic16_storeForReturn): optimized return of 0,
4387 * (genCmp): experimental code for new genCmp which uses PIC18's
4388 special compare&skip instructions. Initial tests fail some times
4389 with variables grater than 1 byte in size, so new code is disabled,
4390 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4392 * (genCast): began a fix to optimize the casting of a bit to another
4393 bit, now assigning a bitfield to another bitfield will fail, sorry,
4394 * src/pic16/main.c: disabled the use of lr-support feature,
4395 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4396 * added some function prototypes, added function _debugf prototype,
4397 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4398 bits with offset (case PO_GPR_BIT),
4399 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4401 * (isBankInstruction): modified to return 0 for no banking instruction,
4402 and 1 for banking instruction,
4403 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4404 caused stop processing pCodes after a inline assembly block,
4405 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4406 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4407 registers when it shouldn't,
4408 * src/pic16/ralloc.c (allocReg): add preliminary support for
4409 supporting a limited set of temporary registers,
4411 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4413 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4414 genDataPointerSet): ensure assignments always copy in MSB to LSB
4416 (loadRegFromAop): recognize CLRH optimization,
4417 (genFunction): optimize RECEIVE iCodes in reentrant functions
4419 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4421 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4422 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4424 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4431 * device/lib/_gptrgetc.c (_gptrgetc),
4432 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4433 instead of sjmp to ret
4434 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4435 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4437 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7419 loaded with the linker search paths (-L arguments) and the libraries
7420 to be linked with the current source (-l arguments). Changes
7421 currently will affect only the pic16 port.
7422 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7423 include path the port specific paths and port specific libraries,

7440 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7442 Documenting changes from previous commits.
7443 * configure.in (version 1.56),
7444 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7445 when generating output files to configure the pic16 library,
7446 but now I've commented it out, since gputils aren't installed in the
7447 SF compile farm, so library won't compile
7449 * device/lib/Makefile.in (version 1.56): initially I've added in
7450 target 'all' the prerequestive 'model-pic16' so it compiled the
7451 pic16 library, but now I've commented it out for the same reasons
7453 * added targets 'model-pic16' and 'objects-pic16' to compile the
7455 * added target 'port-specific-objects-pic16' to handle the
7456 generated libraries and copy them into the build/ directory
7457 * added target 'clean-intermediate-pic16' to clean intermediate
7458 files into pic16 directory
7459 * in target 'installdirs' added line to create directory pic16 in
7460 the installation path
7462 * device/include/Makefile.in (version 1.11): in target 'install'
7463 added lines to copy all header files to installation path,
7464 * in target 'installdirs' added line create directory for pic16
7465 headers in the installation path
7467 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7480 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7481 option so that it actually works. Made it specific to the z80, since
7482 the gbz80 doesn't have these kinds of I/O ports.
7484 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7486 * device/include/z180.h,

7499 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7501 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7502 changed interrupt vector table generation to only emit declared vectors.
7503 * device/include/Makefile.in: added missing backslash
7504 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7508 Mainly changes to support compilation of the device libraries
7509 * src/pic16/device.c: stack is allocated via symbol and not
7510 via literal number. The symbol is placed in the corresponding
7511 position of the data ram
7512 * (pic16_dump_section): relocatable and absolute uninitialized
7513 data are now emitted in sorted order to reduce section naming,
7514 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7515 weren't marked as being in the access bank,
7517 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7519 Added portion of GNU PIC Library under the directory
7520 device/include/pic16 and device/lib/pic16. These files
7521 contain the declarations of SFRs for the PIC18Fxx2 devices.
7522 The directory is initialized via configure from toplevel.
7524 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7526 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7527 the spilllocations to be compared correctly
7529 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7531 * src/SDCCast.c (decorateType): fixed bug introduced today
7533 2004-01-12 Borut Razem <borut.razem AT siol.net>

7551 * doc/sdccman.lyx: Moved and added some sections, small changes
7552 all over. Telling LaTeX to be less strict with word spacing
7553 to better keep the right margin. Changed some notes about
7554 maintainance of the ports in section 3.2.1 - is it OK like this?
7556 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7593 UPPER for immediate operands,
7594 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7596 * src/pic16/peeph.def: all peepholes with movff are commented out,
7597 because there is a problem in the pcode peep optimizer,
7598 * src/pic16/ralloc.c: the register allocator can now reuse local

7600 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7602 Added file src/pic16/NOTES with information about program writing on
7603 the current port version.

7635 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7638 * src/z80/main.c: added missed needLinkerScript flags (more than
7639 one port structure defined in these file)
7640 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7656 needLinkerScript flag
7658 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7659 * src/pic/glue.c: added variable udata_section_name to
7660 override default uninitialized data segment definition for

7663 directive when no overlay data exist
7664 * (picglue): modified to emit uninitialized data segment
7665 according to udata_section_name

7675 2004-01-07 Borut Razem <borut.razem AT siol.net>
7677 * support/scripts/sdcc.nsi: update PATH
7678 * support/scripts/sdcc.ico: craeted

7691 include information about variables allocated to the overlay
7694 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7696 * as/mcs51/lkmain.c: Help about -Y option

7708 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7710 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7711 (default behaviour).
7713 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7715 A python script to validate compiler diagnostic messages. It can be
7716 used to verify that sdcc complains about bad c source code and
7717 gives a good location of the error.
7718 * support/valdiag/Makefile,
7719 * support/valdiag/valdiag.py,
7720 * support/valdiag/tests/*

7737 Bug reported from Jesus Calvino-Fraga
7739 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7741 * sdcc.spec: updated
7742 * device/include/Makefile.in: don't install CVS directories
7743 * device/lib/Makefile.in: added removal of CVS directories after install
7744 * doc/Makefile: fixed install, added local_icons
7745 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7746 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7747 * src/ds390/gen.c (genRightShift): fixed bug #870788
7748 * src/SDCCast.c (decorateType): fixed bug #870781
7750 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7752 PIC16 port related changes:
7753 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7754 added variable stackPos,
7756 * gen.c: genCall, assignResultValue: added support for
7757 pushing/retrieving function parameters to/from stack,
7758 genFunction,genEndFunction: setup stack frame for the
7760 genAddrOf: will be changed according to bug 863624
7762 * added files genutils.c and genutils.h which contain gen*
7763 debugged and optimised functions extracted from gen.c
7765 * glue.c: added variable 'externs' which holds extern symbols,
7766 pic16emitRegularMap: is modified to properly handle relocatable
7767 symbols under the new scheme,
7768 pic16createInterruptVect: is modified
7769 pic16printPublics: is modified to emit 'global' assembler directives,
7770 added pic16_printExterns to print extern symbols,
7771 pic16glue: initializes stack/frame pointer in the beginning of
7772 the assembly output. Temporary hack, will be corrected later,
7773 because gplink yet does not support stack and SDCC does not
7774 yet support a type of crt0.o object to create the final binary.
7776 * Removed many lines that contain 8051 legacy code.
7777 * The code is finally placed under a 'code' directive.
7778 * Added port specific options.
7780 * _process_pragma: simplified since now we do not need *special*
7781 include file to define SFR registers. But a separate header
7782 will be needed. This will be developed later.
7783 * _pic16_parseOptions: added, parses port specific options:
7784 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7785 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7786 --preplace-udata-with=
7788 * _pic16_setDefaultOptions: modified to initialize section names,
7789 but hack is temporarly out of order since it needs improvement.
7790 * _pic16_genAssemblerPreamble: configuration words are emitted by
7791 their address instead of their name. This part is incomplete and
7792 supports only the 18Fxx2 devices. Other devices will emit an error
7793 during assembly since they do not contain the same set of config
7795 * _pic16_genIVT: is modified,
7797 * pcode.c: added definitions for some hardware registers that are needed
7799 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7800 All PCI entries are updated. Now LFSR is supported.
7801 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7802 * added pic16_newpCodeOpLit2 to support instructions with
7803 two literal arguments
7804 * pic16_pCode2str: corrected code that emits assembler instructions
7805 with two literal operands and those that have an access bit modifier
7806 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7807 this fixes a bug which caused some labels to be lost, when an
7808 assembler directive was added, i.e. banksel,
7809 * pic16_FixRegisterBanking: improved logic that causes the insertion
7811 * InlineFunction: functions that are called once, are not any more
7812 inlined. This can be a port option in the future,
7814 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7816 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7817 hold the corresponding uninitialized symbols,
7818 * pic16_allocProcessorRegister: registers have explicit marked the
7820 * pic16_allocInternalRegister: registers are explicit marked as
7822 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7823 processing list, so bit registers were lost,
7826 * ralloc.h: added field 'accessBank' and original symbol operand
7827 in register definition,
7828 * removed the field isMapped from register definition,
7830 ** Several functions have been removed from various sources:
7831 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7832 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7833 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7834 pic16_assignRelocatableRegisters
7836 ** others have been introduced:
7837 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7838 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7840 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7842 * support/scripts/inc2h.pl: changed definition of BIT_AT
7843 to emit 'sbit at' instead of 'bit at'. This was a request.
7845 PIC16 port related preliminary changes:
7846 * gen.c: prefixed function popRegFromString with
7847 pic16_ and all references to it corrected
7848 * pcode.c: all pic16_pc_* hardware registers prefixed
7849 with underscore (_),
7850 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7851 * ralloc.c: newReg(): when register is REG_SFR then
7852 set address to rIdx,
7853 pic16_allocProcessorRegister(): marks register wasUsed=0
7854 pic16_writeUsedRegs(): added a call to assign processor
7855 registers via pic16_assignFixedRegisters
7857 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7859 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7860 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7861 variables in unused register banks. Also the SSEG is placed
7862 wherever there is enough space for it, and IDATA can be anywhere
7863 in internal RAM. For now compile using -Wl-Y[stack_size].
7864 The mem file is different for this option as well, since it
7865 makes no sense of talking about DSEG lenght.
7867 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7869 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7870 in certain cases, e.g. when ROM assignment, patch provided
7871 from Albert den Haan.
7873 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8924 iCodes that originated them. Put this information to use
8925 with a new peephole rule condition "notVolatile" so that
8926 the rules can be aggressive yet still safe.
8931 * src/mcs51/peeph.def
8933 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8937 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8938 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8939 if the left or right operand symbols have the accuse flag set.
8941 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8943 Changed the type of the result of the ! (NOT) operator to char;
8944 previously it returned the same type as the source. This allows
8945 us to eliminate all the genFloatNot functions (all of its target
8946 implementations were very buggy) since !float can use the same
8949 * src/SDCCicode.c (ast2iCode): ! returns char

8958 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8959 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8960 during interrupts. Ensure WSAVE is located at a shared bank address.
8961 2. Fixed page selection in some places
8962 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8963 the registers name strings.
8964 4. Fixed "signed / unsigned compare" compiler warnings.
8965 5. The PIC port manages its own allocation of the general purpose
8966 registers, but makes no attempt to reuse them. As a result when
8967 compiling it soon runs out of general purpose registers. Some
8968 additional code was added to the files pcode.c and device.c to walk
8969 through the function call tree and rename the registers so that they
8979 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8986 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8988 Made bitfield a distinct type from bit so that bitfields
8989 convert as per ANSI C and bits retain their traditional
8990 boolean style behaviour. Implemented bitfield support in
8998 * src/ds390/gen.c: bit v bitfield split
8999 * src/z80/gen.c: New support for bitfields
9000 * support/regression/tests/bitfields.c: reenabled z80,
9003 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9005 Rules 246.x, 247.x relate to bitfields, the others speed up
9006 access to xdata mapped I/O devices.
9008 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9010 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9012 Cleaned up genPackBits and genUnpackBits and added two helper
9013 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9014 for literal assignments in genPackBits (thanks to Frieder for
9020 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9022 Fixed bug #748310 (pointer to function type mishandled when the
9023 function name is omitted). Also fixed a SIGSEGV when a function
9024 attribute (reentrant, etc) is used on a non-function or on a
9025 function but misplaced before the parameter list.

9052 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9054 Made the constant following the "interrupt" keyword optional. If
9055 omitted, the function will not automatically be given an entry
9056 in the interrupt vector table (similar to #pragma NOIV, but
9057 less syntacticly kludgy). The interrupt number is also now
9058 range checked. Also fixed a bug in the high order bit example

9518 * device/lib/gbz80/mul.s
9519 * device/lib/gbz80/stubs.s
9520 * device/lib/z80/mul.s
9521 * device/lib/z80/stubs.s
9522 * src/SDCCsymt.c (initCSupport)
9524 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9526 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9527 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9528 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9529 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9532 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9534 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9535 the regression tests I'm not brave enough to enable 245.b, 245.c
9536 * doc/sdccman.lyx: added latex preamble for hyperref package.
9537 Using pdflatex this will give you a hyperlinked pdf file with
9538 bookmarks. (prepend '%' before /usepackage if this breaks something)
9540 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9550 * src/SDCCglue.c (printIval): fixed bug #739934
9552 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
9554 Applied patch from bug 737905 (renamed yylineo to mylineno):
9561 * src/pic16/pcode.c: Cleaned warnings
9562 * src/pic16/pcodeflow.c: Cleaned warnings
9563 * src/pic16/pcoderegs.c: Cleaned warnings

9574 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9576 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9578 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9579 it can be defined with CFLAGS when running configure
9580 * src/SDCCmain.c: fixed compiling + linking with object files
9582 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9584 * configure.in: configure for pic16 port,
9585 added --disable-pic16-port
9586 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9587 * src/SDCCmain.c: linkOptions is changed to set *,
9588 added if/endif conditional macros to remove options help
9589 messages from optionsTable when a port is not configured, added
9590 support for the PIc16 port in the ports table, when executing
9591 the compiler with no port specified on command line, a default
9592 port is selected with the new macro DEFAULT_PORT which is
9593 defined in port.h, in setDefaultOptions() linkOptions is removed
9594 from initialization assignment, since now it is a set,
9595 parseCmdLine uses setParseWithComma for linkOptions, in
9596 linkEdit() linkOptions are accessed with new function indexSet()
9597 which returns the i'th item of a set variable. See SDCCset.c, in
9598 linkEdit() when calling buildCmdLine(), added linkOptions as
9599 last argument. Now users can pass arguments to gplink via the
9600 -Wl option, main() uses pic16glue() to glue up pic16 programs
9601 * src/SDCCpeeph.c: various changes to support pic16
9602 * src/SDCCset.c: added function void *indexSet(set *, int) to

9610 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9612 * src/pic16/glue.c: commented out some error producing lines
9613 * src/pic16/main.c: __config directives are commented out to stop
9614 gpasm complaining and test the linkage with gplink, _linkCmd and
9615 _asmCmd changed to be more gplink and gpasm friendly
9616 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9617 produced an error when parsed, peep rule 12 is added to utilize
9618 movff, but it is commented out since the pCode does not support
9619 yet a command with 2 address arguments
9621 2003-05-18 <johan AT balder>
9623 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9624 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9625 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9648 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9650 2003-05-11 Borut Razem <borut.razem AT siol.net>
9652 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9653 the path of bin directory, so that PATH is the only env. variable, which has to be set
9654 in case of standard installation.
9655 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10684 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10686 * in \sdcc\as\mcs51\ changed these files in order to create an
10687 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10688 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10689 following files to include the previous two files: aslink.dsp,
10690 Makefile.aslink, Makefile.bcc, and Makefile.in.
10692 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10693 .adb instead of .cdb
10695 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10697 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10698 value from option --iram-size.
10700 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10702 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10705 2002-09-18 <wiml AT hhhh.org>
10707 * SDCClrange.h: exposed setFromRange() and setToRange()
10708 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10709 packRegsForAccUse() (bug 542397)
10710 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10711 multiple times and emitting the fetch operations more than once
10712 added aopGetUsesAcc() function to allow binary operators to
10713 fetch their operands in the correct order; made genMinus() emit
10714 compact code for X = LITERAL - Y
10716 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10717 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10718 sprintf() in line 1267.
10720 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10721 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10724 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10725 Changes to aslink (All the changes are marked with 'JCF'):
10727 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10730 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10731 area BSEG. Also moves, if possible, the DATA area down into the internal
10732 ram so more space is available.
10734 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10737 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10738 not bytes. Function summary() which creates a memory usage summary
10739 file with extension .mem. Reports of overlaping stack and small stack
10740 size. If the space for the stack is less than 16 bytes aslink trows a
10743 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10744 the 8051. Option 'y' for memory summary output file.
10746 Changes to sdcc (All the changes are marked with 'JCF'):
10748 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10750 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10751 overlaying area for it (uses RegBankUsed[4]).
10753 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10754 bank zero as used by default. By default aslink locates the stack
10755 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10756 the creation of the .mem file. Delegates the allocation of data area
10757 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10758 the begining of the stack area to aslink.
10760 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10761 glue() in SDCCglue.c creates an area for it.
10763 2002-09-03 Borut Razem <borut.razem AT siol.net>
10764 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10765 sdcc/src/pic/glue.c:
10766 introduced atexit() handler for teporay files removal in case of
10767 errors, assertions, ...
10769 2002-08-29 Borut Razem <borut.razem AT siol.net>
10770 * sdcc/support/cpp2/auto-host_vc_in.h:
10771 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10772 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10773 Maybe there is a similar problem with BORLANDC? It should be checked!
10775 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10776 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10777 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10778 was not executed, and the compiler (cl) launched a warning:
10779 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10781 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10782 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10794 - added Release configuration in VS projects
10795 - review of compiler an linker options
10796 - VC .exe files are generated in bin_vc directory, not to interfere
10797 with binaries generated from other projects (cygwin, mingw, bcc ...)
10799 * sdcc/src/yacc.dsp: added
10801 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10802 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10803 and insert the version number definitions from .version
10805 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10807 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10808 added - genarate auto-host.h using auto-host_vc_in.h as template
10811 removed from CVS, generated automatically
10813 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10814 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10816 2002-08-11 Borut Razem <borut.razem AT siol.net>
10817 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10819 2002-08-10 Borut Razem <borut.razem AT siol.net>
10820 * src/SDCCmain.c (main):
10821 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10822 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10823 The consequence was that some temporary files were not removed.
10826 unification of code in functions tempfilename() and tempfile():
10827 function tempnam() is defined in Visual Studio 6.0 and .NET
10829 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10831 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10832 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10833 - removed compiler command line option /WX: Treats all warnings as errors
10834 - update a list of source files, included into the project
10836 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10837 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10838 changed project type to Generic Project so that can be correcly converted to VS.NET project
10840 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10842 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10844 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10846 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10847 added return 0 statements after assert() to make compiler happy
10849 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10850 added newline in the def file to keep MSC compiler satisfied
10852 * sdcc/src/z80/gen.c:
10853 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10854 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10855 - solved MSC error in function aopDump()
10857 * sdcc_vc.h: define PREFIX as "\\sdcc"
10859 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11032 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11034 * sdcc/src/SDCCloop.c:
11035 Previous fix was not good. basic blocks that have "break" or "return" are
11036 not really partof a loop , but live ranges used in these blocks should
11037 be live thru the entire loop, so set partOfLoop but don't add them to
