956 genRightShift): fixed bug with non-constant bit shift stored to
957 a volatile result (SF Open Discussion forum thread #1616749).
958 Single byte case is not yet optimized.

2861 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2863 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2864 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2866 One basic decision: e.g. src/clean.mk includes further files. In order
2867 to make this work there are two solutions:
2868 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2869 run configure on them. This way they can use
2870 'include $(srcdir)/port-clean.mk'
2871 - always include clean.mk by the Makefile at the same level. To avoid
2872 that `make clean` tries to include and build Makefile.dep the
2873 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2874 implemented, because now even `make uninstall` doesn't create
2875 Makefile.in. clean.mk could be eliminated by pasting it in
2878 * debugger/mcs51/Makefile.in: build own objects from library sources
2879 (SLIB, SDCC) in current directory
2881 * configure, configure.in: renamed --disable-device-lib-build in
2882 --disable-device-lib; added --enable-doc, the required tools are
2883 searched by configure; added result message; the toolchain for the
2884 belonging ports are now only built, if the port is enabled.
2886 * support/regression/*: all output is written in directory gen, because
2887 the fwk and ports directories don't livet in the build tree using vpath
2889 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2890 --disable-device-lib, added --enable-doc, added section VPATH
2892 * sim/ucsim/configure.in,
2893 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2894 z80 are enabled by default
2896 2006-04-24 Raphael Neider <rneider AT web.de>
2898 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2899 to config word, "pic14_"-prefixed some extern functions
2900 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2901 config word has been found
2902 * src/pic/device.h: added prototypes
2903 * src/pic/pcode.c: added "pic14_"-prefix where needed
2904 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2906 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2908 (pic14emitRegularMap): ignore config words,
2909 (pic14createInterruptVect): moved generating __config directives away
2910 (picglue): have __config directives emitted
2912 2006-04-24 Borut Razem <borut.razem AT siol.net>

2920 fixes #1469504 and #1474602,
2921 (pCodeRegOptimizeRegUsage): fixed typo in comment

2925 * device/examples/main8051.c: deleted - it was removed from CVS

3167 implemented patch 1120823 Thanks to Willy De la Court (normal
3168 interrupts need an interrupt number now if they are made critical),
3169 and enabled nesting of critical functions though not for gbz80
3170 (genCritical, genEndCritical): added functions
3171 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3172 * src/z80/mappings.i: added "ei" to all mappings

3184 the left operand is shorter than the result (c* = lit-c* + int),
3186 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3189 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3191 * src/.version: increased version number to 2.5.5
3192 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3193 linking is done manually in pic16 port's _linkEdit,
3194 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3195 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3196 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3197 allocate asmop as AOP_ACC,
3198 (aopForRemat): added parameter 'bool result' in function declaration,
3199 (pic16_aopGet): return AOP_ACC when accessing WREG,
3200 (pic16_popGetTempReg): minor modification,

3211 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3212 call to allocReg, not by manually allocating a new one,
3213 (pic16_assignRegisters): now before going through the register
3214 allocating functions mark all registers as free. This eliminates some
3215 side effects resulting from peephole parser done earlier in the backbone
3217 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3239 (aopForSym, aopOp): increment asmop.allocated if reused,
3240 (freeAsmop): decrement asmop.allocated and check for zero instead of

3267 2006-03-06 Borut Razem <borut.razem AT siol.net>
3269 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3270 made the linker quiet

3275 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3276 which dumps before the function entry point a data byte which represents
3277 the number of the local variables used by the specified function, added
3278 'xinst' for initial support for Extended Instruction Support,
3279 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3280 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3281 port->fun_prefix anymore (may change later),
3282 (genFunction, genEndFunction): do not store/restore local registers for
3283 _main (this should take care the --main-return command line option in
3285 (genOr): removed some legacy pic-port instructions,
3286 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3287 performing operations with SFR's causes data to be written more than
3288 once to each SFR. Perhaps SFRs should be handled in special cases...
3289 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3291 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3292 into account for stack starting position,

3294 --extended or -y for Extended Instruction Support,
3295 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3296 (deassignLRs): *** perhaps the most important change, old 'for' code
3297 (commented out for reference), didn't account for some registers which
3298 were left marked 'not free' after a pointer operation. The change
3299 reduces register usage a lot in some cases
3301 2006-03-04 Borut Razem <borut.razem AT siol.net>

5546 * device/lib/pic16/libc/delay/: NEW, c sources for the delay functions,
5547 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
5548 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
5549 _do_cinit function, because the previous failed when local variables
5550 where not placed in the same memory bank,
5551 * device/lib/pic16/libsdcc/char/: various modifications to improve
5552 library performance,
5553 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
5554 information on the new functions of the c library and more...
5556 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5564 * (genCmp): adapted to new genSkipc semantics
5565 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
5566 on rIfx (genCmp was broken)
5568 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5570 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5571 * src/z80/main.c (_keywords[]),
5572 * src/SDCCglobal.h (struct options),
5574 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5575 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5576 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5577 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5578 always available in leading double underscore form. The C99 support is
5579 mostly missing, but it's a start.
5580 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5581 reserved identifier "__data".
5583 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
5585 * src/mcs51/peeph.def: fixed bug 1170013

5596 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5598 * src/port.h (struct PORT),

5627 immedDom() returning wrong block; probably fixes bug #1160833)
5629 2005-03-20 Borut Razem <borut.razem AT siol.net>
5631 * support/scripts/inc2h.pl: WIN32 port
5633 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5635 * device/lib/makefile.in: added abs.c and labs.c
5637 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5639 * device/include/stdint.h: added
5640 * device/lib/abs.c: added
5641 * device/lib/labs.c: added
5642 * device/include/stdlib.h: added abs() and labs() prototypes

5657 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5659 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5661 * device/lib/printf_large.c: removed inline assembly for portability and
5662 readability. Use printf_fast if speed or size are more important.
5663 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5664 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5666 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5668 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5669 prevent compiler warning
5671 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5673 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5674 moved to level 0 and declared as static. Also they are explicit
5675 placed in access bank. This was necessery because some times they
5676 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5677 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5678 optimizations. Currently only compare to unsigned char is implemented,
5679 * src/pic16/gen.c: added fReturnIdx array,
5680 * (struct resolvedIfx) is moved to gen.h and made public,
5681 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5682 * (aopForSym): added an optimization to directly store in stack of
5683 the operand of a SEND iCode,
5684 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5685 but as registers instead (AOP_REG) using the fReturnIdx array,
5686 * (pic16_freeAsmop): remove the freed register from the
5687 _G.sregsAlloc field,
5688 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5689 a compare of 'WREG',
5690 * (pic16_popGetTempRegCond): changed function prototype, now
5691 function takes also a bitVector argument v which holds the current
5692 set of registers that are allocated for stack access by aopForSym,
5693 registers allocated in aopForSym for accessing stack symbols are not
5694 any more part of the functions usedRegs field,
5695 * (genCall): some times aopOp is called for a stack variable to be
5696 send, aopForSym might perform the push, if this is true make sure
5697 that genCall doesn't push the variable twice by testing _G.resDirect,
5698 * (genFunction): changed testing for unspecified interrupt number
5699 from 256 to INTNO_UNSPEC,
5700 * modified selection scheme of frame pointer generation. Previously
5701 if function did use local registers a frame pointer was generated,
5702 now a frame pointer is generated only if function has arguments
5703 (that need PLUSW2 register access), or has stack arguments, or the
5704 compiler is not instructed to omit the frame pointer,
5705 * (genEndFunction): before restoring local registers that were saved
5706 in the function preamble, also restore the registers that *might*
5707 have been allocated for stack access,
5708 * (genRet): removed some old comments,
5709 * (genCmp, the active (RN's) version): added a call to the
5710 pic16_genCmp_special function to perform the compare with a more
5711 robust and optimized way,
5712 * (genInline): a feature has been added in inline code generation,
5713 which allows a wildcard variable substitution when writing inline
5714 assembly. Code is incomplete and experimental therefore undocumented,
5715 * (genCast): changed order of aopOp for result and right to allow
5716 aopForSym to directly load the result if possible,
5717 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5718 perform an optimized compare on some selected special occasions,
5719 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5720 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5721 generate an IVT any more,
5722 * src/pic16/main.c (pic16_optionsTable): added command line option
5724 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5725 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5727 * src/pic16/NOTES: Raphael Neider added in list of active developers
5728 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5729 jumptable_end to prevent bug #,
5730 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5731 inCond and outCond fields,
5732 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5733 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5734 turn off register spilling,
5735 * (packRegsForOneUse): synced with other ports' versions although it
5736 is not used currently,
5737 * (pic16_packRegisters): added an optimization while reading
5738 structure bitfields, some registers may be saved (malloc code is
5739 decreased by 80 bytes)
5741 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5743 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5744 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5745 this can be optimized more?
5747 2005-03-10 Raphael Neider <rneider AT web.de>
5749 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5750 genNearPointerGet): (hopefully) fixed access to bitfields via
5751 pointers (p->bitN = x; and x = p->bitN; failed)
5753 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5940 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5941 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5942 this might fix SIGSEGVs on MinGW...
5943 * src/SDCCopt.c (killDeadCode): restored original behaviour
5944 (volatile operands might get thrown away though)
5946 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

6426 be extensively tested in the future. Standard disclaimer here.
6427 Library is not automatically build yet. But one can build it by
6428 invoking 'make' inside the libc directory.

6443 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6445 * (genCast): began a fix to optimize the casting of a bit to another
6446 bit, now assigning a bitfield to another bitfield will fail, sorry,

9469 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9471 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9472 loaded with the linker search paths (-L arguments) and the libraries
9473 to be linked with the current source (-l arguments). Changes
9474 currently will affect only the pic16 port.
9475 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9476 include path the port specific paths and port specific libraries,
9477 * gplink command now contains the $3 argument,
9478 * src/pic16/device.h,
9479 * src/pic16/device.c,: structure PIC_device is made public and
9480 renamed to PIC16_device, the same for variable Pics which is renamed

9495 Documenting changes from previous commits.
9496 * configure.in (version 1.56),
9497 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9498 when generating output files to configure the pic16 library,
9499 but now I've commented it out, since gputils aren't installed in the
9500 SF compile farm, so library won't compile
9502 * device/lib/Makefile.in (version 1.56): initially I've added in
9503 target 'all' the prerequestive 'model-pic16' so it compiled the
9504 pic16 library, but now I've commented it out for the same reasons
9506 * added targets 'model-pic16' and 'objects-pic16' to compile the
9508 * added target 'port-specific-objects-pic16' to handle the
9509 generated libraries and copy them into the build/ directory
9510 * added target 'clean-intermediate-pic16' to clean intermediate
9511 files into pic16 directory
9512 * in target 'installdirs' added line to create directory pic16 in
9513 the installation path
9515 * device/include/Makefile.in (version 1.11): in target 'install'
9516 added lines to copy all header files to installation path,
9517 * in target 'installdirs' added line create directory for pic16
9518 headers in the installation path

9533 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9534 option so that it actually works. Made it specific to the z80, since
9535 the gbz80 doesn't have these kinds of I/O ports.
9537 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9539 * device/include/z180.h,

9563 via literal number. The symbol is placed in the corresponding
9564 position of the data ram
9565 * (pic16_dump_section): relocatable and absolute uninitialized
9566 data are now emitted in sorted order to reduce section naming,
9567 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9568 weren't marked as being in the access bank,
9570 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9572 Added portion of GNU PIC Library under the directory
9573 device/include/pic16 and device/lib/pic16. These files
9574 contain the declarations of SFRs for the PIC18Fxx2 devices.
9575 The directory is initialized via configure from toplevel.
9577 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9579 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9580 the spilllocations to be compared correctly
9582 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9584 * src/SDCCast.c (decorateType): fixed bug introduced today

9604 * doc/sdccman.lyx: Moved and added some sections, small changes
9605 all over. Telling LaTeX to be less strict with word spacing
9606 to better keep the right margin. Changed some notes about
9607 maintainance of the ports in section 3.2.1 - is it OK like this?
9609 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9646 UPPER for immediate operands,
9647 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9649 * src/pic16/peeph.def: all peepholes with movff are commented out,
9650 because there is a problem in the pcode peep optimizer,
9651 * src/pic16/ralloc.c: the register allocator can now reuse local
9652 function symbols for another function. This saves register usage.
9653 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9655 Added file src/pic16/NOTES with information about program writing on
9656 the current port version.

9685 gen51Code): more efficient parameter receive for --model-large
9688 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9691 * src/z80/main.c: added missed needLinkerScript flags (more than
9692 one port structure defined in these file)
9693 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9709 needLinkerScript flag
9711 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9712 * src/pic/glue.c: added variable udata_section_name to
9713 override default uninitialized data segment definition for
9714 devices only with SHAREBANK memory (reported from Erik Epetrich)
9715 * (pic14emitOverlay): modified to emit a commented overlay segment
9716 directive when no overlay data exist
9717 * (picglue): modified to emit uninitialized data segment
9718 according to udata_section_name

9728 2004-01-07 Borut Razem <borut.razem AT siol.net>
9730 * support/scripts/sdcc.nsi: update PATH
9731 * support/scripts/sdcc.ico: craeted

9738 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9740 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9742 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

9744 include information about variables allocated to the overlay
9747 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9749 * as/mcs51/lkmain.c: Help about -Y option

9761 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9763 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9764 (default behaviour).
9766 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9768 A python script to validate compiler diagnostic messages. It can be
9769 used to verify that sdcc complains about bad c source code and
9770 gives a good location of the error.
9771 * support/valdiag/Makefile,
9772 * support/valdiag/valdiag.py,
9773 * support/valdiag/tests/*
9775 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9777 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9778 * src/SDCCsymt.c (newEnumType),

9786 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9788 * src/common.h: added ifndef/define/endif macros
9789 around the header file.
9790 Bug reported from Jesus Calvino-Fraga
9792 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9794 * sdcc.spec: updated
9795 * device/include/Makefile.in: don't install CVS directories
9796 * device/lib/Makefile.in: added removal of CVS directories after install
9797 * doc/Makefile: fixed install, added local_icons
9798 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9799 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9800 * src/ds390/gen.c (genRightShift): fixed bug #870788
9801 * src/SDCCast.c (decorateType): fixed bug #870781
9803 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9805 PIC16 port related changes:
9806 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9807 added variable stackPos,
9809 * gen.c: genCall, assignResultValue: added support for
9810 pushing/retrieving function parameters to/from stack,
9811 genFunction,genEndFunction: setup stack frame for the
9813 genAddrOf: will be changed according to bug 863624
9815 * added files genutils.c and genutils.h which contain gen*
9816 debugged and optimised functions extracted from gen.c
9818 * glue.c: added variable 'externs' which holds extern symbols,
9819 pic16emitRegularMap: is modified to properly handle relocatable
9820 symbols under the new scheme,
9821 pic16createInterruptVect: is modified
9822 pic16printPublics: is modified to emit 'global' assembler directives,
9823 added pic16_printExterns to print extern symbols,
9824 pic16glue: initializes stack/frame pointer in the beginning of
9825 the assembly output. Temporary hack, will be corrected later,
9826 because gplink yet does not support stack and SDCC does not
9827 yet support a type of crt0.o object to create the final binary.
9829 * Removed many lines that contain 8051 legacy code.
9830 * The code is finally placed under a 'code' directive.
9831 * Added port specific options.
9833 * _process_pragma: simplified since now we do not need *special*
9834 include file to define SFR registers. But a separate header
9835 will be needed. This will be developed later.
9836 * _pic16_parseOptions: added, parses port specific options:
9837 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9838 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9839 --preplace-udata-with=
9841 * _pic16_setDefaultOptions: modified to initialize section names,
9842 but hack is temporarly out of order since it needs improvement.
9843 * _pic16_genAssemblerPreamble: configuration words are emitted by
9844 their address instead of their name. This part is incomplete and
9845 supports only the 18Fxx2 devices. Other devices will emit an error
9846 during assembly since they do not contain the same set of config
9848 * _pic16_genIVT: is modified,
9850 * pcode.c: added definitions for some hardware registers that are needed
9852 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9853 All PCI entries are updated. Now LFSR is supported.
9854 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9855 * added pic16_newpCodeOpLit2 to support instructions with
9856 two literal arguments
9857 * pic16_pCode2str: corrected code that emits assembler instructions
9858 with two literal operands and those that have an access bit modifier
9859 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9860 this fixes a bug which caused some labels to be lost, when an
9861 assembler directive was added, i.e. banksel,
9862 * pic16_FixRegisterBanking: improved logic that causes the insertion
9864 * InlineFunction: functions that are called once, are not any more
9865 inlined. This can be a port option in the future,
9867 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9869 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9870 hold the corresponding uninitialized symbols,
9871 * pic16_allocProcessorRegister: registers have explicit marked the
9873 * pic16_allocInternalRegister: registers are explicit marked as
9875 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9876 processing list, so bit registers were lost,
9879 * ralloc.h: added field 'accessBank' and original symbol operand
9880 in register definition,
9881 * removed the field isMapped from register definition,
9883 ** Several functions have been removed from various sources:
9884 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9885 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9886 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9887 pic16_assignRelocatableRegisters
9889 ** others have been introduced:
9890 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9891 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9893 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9895 * support/scripts/inc2h.pl: changed definition of BIT_AT
9896 to emit 'sbit at' instead of 'bit at'. This was a request.
9898 PIC16 port related preliminary changes:
9899 * gen.c: prefixed function popRegFromString with
9900 pic16_ and all references to it corrected
9901 * pcode.c: all pic16_pc_* hardware registers prefixed
9902 with underscore (_),
9903 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9904 * ralloc.c: newReg(): when register is REG_SFR then
9905 set address to rIdx,
9906 pic16_allocProcessorRegister(): marks register wasUsed=0
9907 pic16_writeUsedRegs(): added a call to assign processor
9908 registers via pic16_assignFixedRegisters
9910 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9912 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9913 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9914 variables in unused register banks. Also the SSEG is placed
9915 wherever there is enough space for it, and IDATA can be anywhere
9916 in internal RAM. For now compile using -Wl-Y[stack_size].
9917 The mem file is different for this option as well, since it
9918 makes no sense of talking about DSEG lenght.
9920 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9922 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9923 in certain cases, e.g. when ROM assignment, patch provided
9924 from Albert den Haan.
9926 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10169 it breaks with bitfields, extern declarations, and gcse analysis.
10170 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10171 could be assigned through a pointer, so don't complain.

10479 not occur if the control variable is involved with a
10480 relational operator.

10958 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10960 Z80 and MCS51 linkers complaint if a public symbol is defined
10961 in more than one library module:
10965 * as/mcs51/Makefile.in
10967 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10969 A few small changes that speed up the peephole optimizer.
10973 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10975 Try to make the peephole optimizer smarter by maintaining
10976 an association between the assembly source code and the
10977 iCodes that originated them. Put this information to use
10978 with a new peephole rule condition "notVolatile" so that
10979 the rules can be aggressive yet still safe.
10984 * src/mcs51/peeph.def
10986 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10990 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10991 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10992 if the left or right operand symbols have the accuse flag set.
10994 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10996 Changed the type of the result of the ! (NOT) operator to char;
10997 previously it returned the same type as the source. This allows
10998 us to eliminate all the genFloatNot functions (all of its target
10999 implementations were very buggy) since !float can use the same
11002 * src/SDCCicode.c (ast2iCode): ! returns char
11003 * src/mcs51/gen.c (genNot, genNotFloat),
11004 * src/ds390/gen.c (genNot, genNotFloat),
11005 * src/z80/gen.c (genNot, genNotFloat),
11006 * src/pic/gen.c (genNot, genNotFloat),
11007 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11011 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11012 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11013 during interrupts. Ensure WSAVE is located at a shared bank address.
11014 2. Fixed page selection in some places
11015 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11016 the registers name strings.
11017 4. Fixed "signed / unsigned compare" compiler warnings.
11018 5. The PIC port manages its own allocation of the general purpose
11019 registers, but makes no attempt to reuse them. As a result when
11020 compiling it soon runs out of general purpose registers. Some
11021 additional code was added to the files pcode.c and device.c to walk
11022 through the function call tree and rename the registers so that they
11032 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11033 genPlus() & genMinus() when the result is the same as left or right
11035 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11037 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11039 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11041 Made bitfield a distinct type from bit so that bitfields
11042 convert as per ANSI C and bits retain their traditional
11043 boolean style behaviour. Implemented bitfield support in
11051 * src/ds390/gen.c: bit v bitfield split
11052 * src/z80/gen.c: New support for bitfields
11053 * support/regression/tests/bitfields.c: reenabled z80,
11056 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11058 Rules 246.x, 247.x relate to bitfields, the others speed up
11059 access to xdata mapped I/O devices.
11061 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11063 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11065 Cleaned up genPackBits and genUnpackBits and added two helper
11066 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11067 for literal assignments in genPackBits (thanks to Frieder for
11073 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11075 Fixed bug #748310 (pointer to function type mishandled when the
11076 function name is omitted). Also fixed a SIGSEGV when a function
11077 attribute (reentrant, etc) is used on a non-function or on a
11078 function but misplaced before the parameter list.
11080 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11082 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11083 * support/Util/SDCCerr.h,
11084 * support/Util/SDCCerr.c: Added func attr misuse error msg
11086 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11088 Fixed bug #787649 by anonymous
11089 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11090 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11092 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11094 Fixed numerous bitfield problems.
11096 * src/SDCC.y: More bitfield related error checking

11103 * support/regression/tests/bitfields.c: tests added
11105 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11107 Made the constant following the "interrupt" keyword optional. If
11108 omitted, the function will not automatically be given an entry
11109 in the interrupt vector table (similar to #pragma NOIV, but
11110 less syntacticly kludgy). The interrupt number is also now
11111 range checked. Also fixed a bug in the high order bit example
11118 * support/Util/SDCCerr.c
11119 * support/Util/SDCCerr.h

11127 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11129 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11130 be re-activated by defining REDUCE_LITERALS)
11131 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11132 unsigned, but are signed by default
11133 * src/SDCCval.c (constVal): rearranged
11134 * src/SDCCval.c (valMod): preliminary fix
11135 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11175 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11176 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11177 constants are unsigned; added recognition of "u" flag for unsigned
11178 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11179 * src/SDCCval.c (valDiv, valMod): fixed signdness

11641 added if/endif conditional macros to remove options help
11642 messages from optionsTable when a port is not configured, added
11643 support for the PIc16 port in the ports table, when executing
11644 the compiler with no port specified on command line, a default
11645 port is selected with the new macro DEFAULT_PORT which is
11646 defined in port.h, in setDefaultOptions() linkOptions is removed
11647 from initialization assignment, since now it is a set,
11648 parseCmdLine uses setParseWithComma for linkOptions, in
11649 linkEdit() linkOptions are accessed with new function indexSet()
11650 which returns the i'th item of a set variable. See SDCCset.c, in
11651 linkEdit() when calling buildCmdLine(), added linkOptions as
11652 last argument. Now users can pass arguments to gplink via the
11653 -Wl option, main() uses pic16glue() to glue up pic16 programs

11665 * src/pic16/glue.c: commented out some error producing lines
11666 * src/pic16/main.c: __config directives are commented out to stop
11667 gpasm complaining and test the linkage with gplink, _linkCmd and
11668 _asmCmd changed to be more gplink and gpasm friendly
11669 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11670 produced an error when parsed, peep rule 12 is added to utilize
11671 movff, but it is commented out since the pCode does not support
11672 yet a command with 2 address arguments
11674 2003-05-18 <johan AT balder>
11676 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12791 not bytes. Function summary() which creates a memory usage summary
12792 file with extension .mem. Reports of overlaping stack and small stack
12793 size. If the space for the stack is less than 16 bytes aslink trows a
12796 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12797 the 8051. Option 'y' for memory summary output file.
12799 Changes to sdcc (All the changes are marked with 'JCF'):
12801 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12803 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12804 overlaying area for it (uses RegBankUsed[4]).
12806 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12807 bank zero as used by default. By default aslink locates the stack
12808 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12809 the creation of the .mem file. Delegates the allocation of data area
12810 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12811 the begining of the stack area to aslink.
12813 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12814 glue() in SDCCglue.c creates an area for it.
12816 2002-09-03 Borut Razem <borut.razem AT siol.net>
12817 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12818 sdcc/src/pic/glue.c:
12819 introduced atexit() handler for teporay files removal in case of
12820 errors, assertions, ...
12822 2002-08-29 Borut Razem <borut.razem AT siol.net>
12823 * sdcc/support/cpp2/auto-host_vc_in.h:
12824 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12825 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12826 Maybe there is a similar problem with BORLANDC? It should be checked!
12828 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12829 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12830 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12831 was not executed, and the compiler (cl) launched a warning:
12832 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12834 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12835 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12837 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12838 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12840 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12841 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12842 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12843 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12844 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12845 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12846 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12847 - added Release configuration in VS projects
12848 - review of compiler an linker options
12849 - VC .exe files are generated in bin_vc directory, not to interfere
12850 with binaries generated from other projects (cygwin, mingw, bcc ...)
12852 * sdcc/src/yacc.dsp: added
12854 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12855 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12856 and insert the version number definitions from .version
12858 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12860 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12861 added - genarate auto-host.h using auto-host_vc_in.h as template
12864 removed from CVS, generated automatically
12866 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12867 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12869 2002-08-11 Borut Razem <borut.razem AT siol.net>
12870 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12872 2002-08-10 Borut Razem <borut.razem AT siol.net>
12873 * src/SDCCmain.c (main):
12874 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12875 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12876 The consequence was that some temporary files were not removed.
12879 unification of code in functions tempfilename() and tempfile():
12880 function tempnam() is defined in Visual Studio 6.0 and .NET
12882 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12884 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12885 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12886 - removed compiler command line option /WX: Treats all warnings as errors
12887 - update a list of source files, included into the project
12889 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12890 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12891 changed project type to Generic Project so that can be correcly converted to VS.NET project
12893 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12895 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12897 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12899 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12900 added return 0 statements after assert() to make compiler happy
12902 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12903 added newline in the def file to keep MSC compiler satisfied
12905 * sdcc/src/z80/gen.c:
12906 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12907 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12908 - solved MSC error in function aopDump()
12910 * sdcc_vc.h: define PREFIX as "\\sdcc"
12912 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12913 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12950 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12952 2002-03-28 Johan Knol <johan AT balder>
12954 * src/SDCCval.c: fixed bug #532436
12956 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12961 Added -p option. Allows port dependent processor to be specified.
12964 Initialized the new field char *Processor field to NULL in all ports
12967 Compiler generated registers for interrupt context saving
12968 were not getting allocated.
12970 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12973 Fixed left shift. Will promote the left side of a left shift
12974 if a) left shifting more than size of operand or b) when assigned
12975 to something size > size of left side

13085 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13087 * sdcc/src/SDCCloop.c:
13088 Previous fix was not good. basic blocks that have "break" or "return" are
13089 not really partof a loop , but live ranges used in these blocks should
13090 be live thru the entire loop, so set partOfLoop but don't add them to
13093 2002-02-21 <johan AT FRIJA>
13095 * src/SDCCcse.c: fixed bug #514308
13097 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
