30 of string literals (still incomplete),
31 (picglue): removed symbol emission, moved into showAllMemmaps,
32 (emitSymbolSet): new workhorse for symbol output,
33 (pic14emitMaps,pic14printPublics,pic14printExterns): commented out

2788 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2790 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2791 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2793 One basic decision: e.g. src/clean.mk includes further files. In order
2794 to make this work there are two solutions:
2795 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2796 run configure on them. This way they can use
2797 'include $(srcdir)/port-clean.mk'
2798 - always include clean.mk by the Makefile at the same level. To avoid
2799 that `make clean` tries to include and build Makefile.dep the
2800 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2801 implemented, because now even `make uninstall` doesn't create
2802 Makefile.in. clean.mk could be eliminated by pasting it in
2805 * debugger/mcs51/Makefile.in: build own objects from library sources
2806 (SLIB, SDCC) in current directory
2808 * configure, configure.in: renamed --disable-device-lib-build in
2809 --disable-device-lib; added --enable-doc, the required tools are
2810 searched by configure; added result message; the toolchain for the
2811 belonging ports are now only built, if the port is enabled.
2813 * support/regression/*: all output is written in directory gen, because
2814 the fwk and ports directories don't livet in the build tree using vpath
2816 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2817 --disable-device-lib, added --enable-doc, added section VPATH
2819 * sim/ucsim/configure.in,
2820 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2821 z80 are enabled by default
2823 2006-04-24 Raphael Neider <rneider AT web.de>
2825 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2826 to config word, "pic14_"-prefixed some extern functions
2827 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2828 config word has been found
2829 * src/pic/device.h: added prototypes
2830 * src/pic/pcode.c: added "pic14_"-prefix where needed
2831 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2833 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2847 fixes #1469504 and #1474602,
2848 (pCodeRegOptimizeRegUsage): fixed typo in comment

3071 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3073 * src/mcs51/gen.c (genCall): fixed bug 1457608
3075 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3077 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

3080 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3082 * src/SDCCpeeph.c (operandsLiteral): new, added,

3093 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3094 implemented patch 1120823 Thanks to Willy De la Court (normal
3095 interrupts need an interrupt number now if they are made critical),
3096 and enabled nesting of critical functions though not for gbz80
3097 (genCritical, genEndCritical): added functions
3098 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3099 * src/z80/mappings.i: added "ei" to all mappings
3101 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3103 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3104 submitted by the Debian SDCC maintainer Aurelien Jarno:
3105 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3106 archive with gcc 4.1 on mips and wrote the patch"
3108 2006-03-16 Raphael Neider <rneider AT web.de>
3110 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3111 the left operand is shorter than the result (c* = lit-c* + int),
3113 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3116 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3118 * src/.version: increased version number to 2.5.5
3119 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3120 linking is done manually in pic16 port's _linkEdit,
3121 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3122 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3123 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3124 allocate asmop as AOP_ACC,
3125 (aopForRemat): added parameter 'bool result' in function declaration,
3126 (pic16_aopGet): return AOP_ACC when accessing WREG,
3127 (pic16_popGetTempReg): minor modification,
3128 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3129 'pic16_allocWithIdx',
3130 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3131 calling function in absolute addresses,
3132 (genAssign): take into account AOP_ACC asmop,
3133 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

3136 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3138 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3139 call to allocReg, not by manually allocating a new one,
3140 (pic16_assignRegisters): now before going through the register
3141 allocating functions mark all registers as free. This eliminates some
3142 side effects resulting from peephole parser done earlier in the backbone
3144 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3146 * src/SDCCicode.c (geniCodeLogic),

3165 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3166 (aopForSym, aopOp): increment asmop.allocated if reused,
3167 (freeAsmop): decrement asmop.allocated and check for zero instead of
3169 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3170 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3171 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3194 2006-03-06 Borut Razem <borut.razem AT siol.net>
3196 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3197 made the linker quiet
3199 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3201 * src/pic16/gen.c (genPcall): fixed bug #1443644
3202 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3203 which dumps before the function entry point a data byte which represents
3204 the number of the local variables used by the specified function, added
3205 'xinst' for initial support for Extended Instruction Support,
3206 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3207 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3208 port->fun_prefix anymore (may change later),
3209 (genFunction, genEndFunction): do not store/restore local registers for
3210 _main (this should take care the --main-return command line option in
3212 (genOr): removed some legacy pic-port instructions,
3213 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3214 performing operations with SFR's causes data to be written more than
3215 once to each SFR. Perhaps SFRs should be handled in special cases...
3216 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3218 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3219 into account for stack starting position,
3220 (struct OPTIONS pic16_optionsTable): added command line argument
3221 --extended or -y for Extended Instruction Support,
3222 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3223 (deassignLRs): *** perhaps the most important change, old 'for' code
3224 (commented out for reference), didn't account for some registers which
3225 were left marked 'not free' after a pointer operation. The change
3226 reduces register usage a lot in some cases
3228 2006-03-04 Borut Razem <borut.razem AT siol.net>
3230 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5545 * src/SDCCdflow.c (computeDataFlow),
5547 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
5549 * src/SDCCcflow.c (*),
5551 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
5552 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5553 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5554 immedDom() returning wrong block; probably fixes bug #1160833)
5556 2005-03-20 Borut Razem <borut.razem AT siol.net>
5558 * support/scripts/inc2h.pl: WIN32 port
5560 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5562 * device/lib/makefile.in: added abs.c and labs.c
5564 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5566 * device/include/stdint.h: added
5567 * device/lib/abs.c: added
5568 * device/lib/labs.c: added
5569 * device/include/stdlib.h: added abs() and labs() prototypes
5570 * device/lib/libsdcc.lib: added abs and labs
5571 * device/include/float.h,
5572 * device/lib/_fsmul.c,
5573 * device/lib/printf_fast.c,
5574 * device/lib/printf_tiny.c: updated comments
5576 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5578 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5581 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5583 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5584 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5586 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5588 * device/lib/printf_large.c: removed inline assembly for portability and
5589 readability. Use printf_fast if speed or size are more important.
5590 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5591 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5593 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5595 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5596 prevent compiler warning
5598 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5600 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5601 moved to level 0 and declared as static. Also they are explicit
5602 placed in access bank. This was necessery because some times they
5603 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5604 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5605 optimizations. Currently only compare to unsigned char is implemented,
5606 * src/pic16/gen.c: added fReturnIdx array,
5607 * (struct resolvedIfx) is moved to gen.h and made public,
5608 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5609 * (aopForSym): added an optimization to directly store in stack of
5610 the operand of a SEND iCode,
5611 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5612 but as registers instead (AOP_REG) using the fReturnIdx array,
5613 * (pic16_freeAsmop): remove the freed register from the
5614 _G.sregsAlloc field,
5615 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5616 a compare of 'WREG',
5617 * (pic16_popGetTempRegCond): changed function prototype, now
5618 function takes also a bitVector argument v which holds the current
5619 set of registers that are allocated for stack access by aopForSym,
5620 registers allocated in aopForSym for accessing stack symbols are not
5621 any more part of the functions usedRegs field,
5622 * (genCall): some times aopOp is called for a stack variable to be
5623 send, aopForSym might perform the push, if this is true make sure
5624 that genCall doesn't push the variable twice by testing _G.resDirect,
5625 * (genFunction): changed testing for unspecified interrupt number
5626 from 256 to INTNO_UNSPEC,
5627 * modified selection scheme of frame pointer generation. Previously
5628 if function did use local registers a frame pointer was generated,
5629 now a frame pointer is generated only if function has arguments
5630 (that need PLUSW2 register access), or has stack arguments, or the
5631 compiler is not instructed to omit the frame pointer,
5632 * (genEndFunction): before restoring local registers that were saved
5633 in the function preamble, also restore the registers that *might*
5634 have been allocated for stack access,
5635 * (genRet): removed some old comments,
5636 * (genCmp, the active (RN's) version): added a call to the
5637 pic16_genCmp_special function to perform the compare with a more
5638 robust and optimized way,
5639 * (genInline): a feature has been added in inline code generation,
5640 which allows a wildcard variable substitution when writing inline
5641 assembly. Code is incomplete and experimental therefore undocumented,
5642 * (genCast): changed order of aopOp for result and right to allow
5643 aopForSym to directly load the result if possible,
5644 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5645 perform an optimized compare on some selected special occasions,
5646 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5647 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5648 generate an IVT any more,
5649 * src/pic16/main.c (pic16_optionsTable): added command line option
5651 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5652 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5654 * src/pic16/NOTES: Raphael Neider added in list of active developers
5655 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5656 jumptable_end to prevent bug #,
5657 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5658 inCond and outCond fields,
5659 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5660 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5661 turn off register spilling,
5662 * (packRegsForOneUse): synced with other ports' versions although it
5663 is not used currently,
5664 * (pic16_packRegisters): added an optimization while reading
5665 structure bitfields, some registers may be saved (malloc code is
5666 decreased by 80 bytes)
5668 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5670 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5671 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5672 this can be optimized more?
5674 2005-03-10 Raphael Neider <rneider AT web.de>
5676 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5677 genNearPointerGet): (hopefully) fixed access to bitfields via
5678 pointers (p->bitN = x; and x = p->bitN; failed)
5680 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5723 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5724 to keep the correct label reference count when adding/removing references
5725 to labels. A peephole file using this is appended to patch #1144962.

5868 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5869 this might fix SIGSEGVs on MinGW...

6313 generated for switch statements. For now you need to set the
6314 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6315 Now 4 algorithms for mcs51 jumptable generation are used:
6316 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

6348 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6350 * added libc directory. The current version of LibC contains string
6351 functions, ctype functions and macros and some functions of the
6352 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6353 be extensively tested in the future. Standard disclaimer here.
6354 Library is not automatically build yet. But one can build it by
6355 invoking 'make' inside the libc directory.

6366 * (pic16_storeForReturn): optimized return of 0,
6367 * (genCmp): experimental code for new genCmp which uses PIC18's
6368 special compare&skip instructions. Initial tests fail some times
6369 with variables grater than 1 byte in size, so new code is disabled,
6370 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6372 * (genCast): began a fix to optimize the casting of a bit to another
6373 bit, now assigning a bitfield to another bitfield will fail, sorry,

6382 and 1 for banking instruction,
6383 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6384 caused stop processing pCodes after a inline assembly block,
6385 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6387 registers when it shouldn't,
6388 * src/pic16/ralloc.c (allocReg): add preliminary support for
6389 supporting a limited set of temporary registers,
6391 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6393 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

6397 (genFunction): optimize RECEIVE iCodes in reentrant functions
6399 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6401 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6410 * device/lib/_gptrget.c (_gptrget),
6411 * device/lib/_gptrgetc.c (_gptrgetc),

9396 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9398 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9399 loaded with the linker search paths (-L arguments) and the libraries
9400 to be linked with the current source (-l arguments). Changes
9401 currently will affect only the pic16 port.
9402 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9403 include path the port specific paths and port specific libraries,
9404 * gplink command now contains the $3 argument,
9405 * src/pic16/device.h,
9406 * src/pic16/device.c,: structure PIC_device is made public and
9407 renamed to PIC16_device, the same for variable Pics which is renamed

9422 Documenting changes from previous commits.
9423 * configure.in (version 1.56),
9424 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9425 when generating output files to configure the pic16 library,
9426 but now I've commented it out, since gputils aren't installed in the
9427 SF compile farm, so library won't compile
9429 * device/lib/Makefile.in (version 1.56): initially I've added in
9430 target 'all' the prerequestive 'model-pic16' so it compiled the
9431 pic16 library, but now I've commented it out for the same reasons
9433 * added targets 'model-pic16' and 'objects-pic16' to compile the
9435 * added target 'port-specific-objects-pic16' to handle the
9436 generated libraries and copy them into the build/ directory
9437 * added target 'clean-intermediate-pic16' to clean intermediate
9438 files into pic16 directory
9439 * in target 'installdirs' added line to create directory pic16 in
9440 the installation path

9443 added lines to copy all header files to installation path,
9444 * in target 'installdirs' added line create directory for pic16
9445 headers in the installation path

9461 option so that it actually works. Made it specific to the z80, since
9462 the gbz80 doesn't have these kinds of I/O ports.
9464 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9466 * device/include/z180.h,

9490 via literal number. The symbol is placed in the corresponding
9491 position of the data ram
9492 * (pic16_dump_section): relocatable and absolute uninitialized
9493 data are now emitted in sorted order to reduce section naming,
9494 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9495 weren't marked as being in the access bank,
9497 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9499 Added portion of GNU PIC Library under the directory
9500 device/include/pic16 and device/lib/pic16. These files
9501 contain the declarations of SFRs for the PIC18Fxx2 devices.
9502 The directory is initialized via configure from toplevel.

9531 * doc/sdccman.lyx: Moved and added some sections, small changes
9532 all over. Telling LaTeX to be less strict with word spacing
9533 to better keep the right margin. Changed some notes about
9534 maintainance of the ports in section 3.2.1 - is it OK like this?
9536 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9538 SDCC source changes:
9539 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9545 processor registers declared internally by the port are emitted in
9546 the translation as equates,
9547 * src/pic16/gen.c: inline code is passed unprocessed to the

9573 UPPER for immediate operands,
9574 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9576 * src/pic16/peeph.def: all peepholes with movff are commented out,
9577 because there is a problem in the pcode peep optimizer,
9578 * src/pic16/ralloc.c: the register allocator can now reuse local

9671 include information about variables allocated to the overlay
9674 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9676 * as/mcs51/lkmain.c: Help about -Y option

9688 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9690 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9691 (default behaviour).
9693 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9695 A python script to validate compiler diagnostic messages. It can be
9696 used to verify that sdcc complains about bad c source code and
9697 gives a good location of the error.
9698 * support/valdiag/Makefile,
9699 * support/valdiag/valdiag.py,
9700 * support/valdiag/tests/*
9702 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9715 * src/common.h: added ifndef/define/endif macros
9716 around the header file.
9717 Bug reported from Jesus Calvino-Fraga
9719 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9721 * sdcc.spec: updated
9722 * device/include/Makefile.in: don't install CVS directories
9723 * device/lib/Makefile.in: added removal of CVS directories after install
9724 * doc/Makefile: fixed install, added local_icons
9725 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9726 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9727 * src/ds390/gen.c (genRightShift): fixed bug #870788
9728 * src/SDCCast.c (decorateType): fixed bug #870781
9730 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9732 PIC16 port related changes:
9733 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9734 added variable stackPos,
9736 * gen.c: genCall, assignResultValue: added support for
9737 pushing/retrieving function parameters to/from stack,
9738 genFunction,genEndFunction: setup stack frame for the
9740 genAddrOf: will be changed according to bug 863624
9742 * added files genutils.c and genutils.h which contain gen*
9743 debugged and optimised functions extracted from gen.c
9745 * glue.c: added variable 'externs' which holds extern symbols,
9746 pic16emitRegularMap: is modified to properly handle relocatable
9747 symbols under the new scheme,
9748 pic16createInterruptVect: is modified
9749 pic16printPublics: is modified to emit 'global' assembler directives,
9750 added pic16_printExterns to print extern symbols,
9751 pic16glue: initializes stack/frame pointer in the beginning of
9752 the assembly output. Temporary hack, will be corrected later,
9753 because gplink yet does not support stack and SDCC does not
9754 yet support a type of crt0.o object to create the final binary.
9756 * Removed many lines that contain 8051 legacy code.
9757 * The code is finally placed under a 'code' directive.
9758 * Added port specific options.
9760 * _process_pragma: simplified since now we do not need *special*
9761 include file to define SFR registers. But a separate header
9762 will be needed. This will be developed later.
9763 * _pic16_parseOptions: added, parses port specific options:
9764 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9765 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9766 --preplace-udata-with=
9768 * _pic16_setDefaultOptions: modified to initialize section names,
9769 but hack is temporarly out of order since it needs improvement.
9770 * _pic16_genAssemblerPreamble: configuration words are emitted by
9771 their address instead of their name. This part is incomplete and
9772 supports only the 18Fxx2 devices. Other devices will emit an error
9773 during assembly since they do not contain the same set of config
9775 * _pic16_genIVT: is modified,
9777 * pcode.c: added definitions for some hardware registers that are needed
9779 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9780 All PCI entries are updated. Now LFSR is supported.
9781 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9782 * added pic16_newpCodeOpLit2 to support instructions with
9783 two literal arguments
9784 * pic16_pCode2str: corrected code that emits assembler instructions
9785 with two literal operands and those that have an access bit modifier
9786 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9787 this fixes a bug which caused some labels to be lost, when an
9788 assembler directive was added, i.e. banksel,
9789 * pic16_FixRegisterBanking: improved logic that causes the insertion
9791 * InlineFunction: functions that are called once, are not any more
9792 inlined. This can be a port option in the future,
9794 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9796 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9797 hold the corresponding uninitialized symbols,
9798 * pic16_allocProcessorRegister: registers have explicit marked the
9800 * pic16_allocInternalRegister: registers are explicit marked as
9802 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9803 processing list, so bit registers were lost,
9806 * ralloc.h: added field 'accessBank' and original symbol operand
9807 in register definition,
9808 * removed the field isMapped from register definition,
9810 ** Several functions have been removed from various sources:
9811 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9812 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9813 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9814 pic16_assignRelocatableRegisters
9816 ** others have been introduced:
9817 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9818 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9820 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9822 * support/scripts/inc2h.pl: changed definition of BIT_AT
9823 to emit 'sbit at' instead of 'bit at'. This was a request.
9825 PIC16 port related preliminary changes:
9826 * gen.c: prefixed function popRegFromString with
9827 pic16_ and all references to it corrected
9828 * pcode.c: all pic16_pc_* hardware registers prefixed
9829 with underscore (_),
9830 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9831 * ralloc.c: newReg(): when register is REG_SFR then
9832 set address to rIdx,
9833 pic16_allocProcessorRegister(): marks register wasUsed=0
9834 pic16_writeUsedRegs(): added a call to assign processor
9835 registers via pic16_assignFixedRegisters
9837 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9839 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9840 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9841 variables in unused register banks. Also the SSEG is placed
9842 wherever there is enough space for it, and IDATA can be anywhere
9843 in internal RAM. For now compile using -Wl-Y[stack_size].
9844 The mem file is different for this option as well, since it
9845 makes no sense of talking about DSEG lenght.
9847 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9849 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9850 in certain cases, e.g. when ROM assignment, patch provided
9851 from Albert den Haan.
9853 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9996 * src/mcs51/peephole.def,
9997 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9998 (allows non-interrupt and interrupt code to safely compete for a resource

10759 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10761 Fixed bug #621531 (const & volatile confusion in the type chain).
10762 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10858 copied from genNearPointerSet()
10859 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10860 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10861 If they pop r0/r1 they must be called in the opposite order than aopOp().
10862 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10863 (resp. --stack-auto), prepared for --xstack

10876 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10877 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10878 type for bits was changed. It resulted in bit variables becoming
10879 global, which is not permitted in PIC 14 assembly output.
10881 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10883 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10885 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10887 Z80 and MCS51 linkers complaint if a public symbol is defined

10894 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10896 A few small changes that speed up the peephole optimizer.
10900 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10902 Try to make the peephole optimizer smarter by maintaining
10903 an association between the assembly source code and the
10904 iCodes that originated them. Put this information to use
10905 with a new peephole rule condition "notVolatile" so that
10906 the rules can be aggressive yet still safe.
10911 * src/mcs51/peeph.def
10913 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10917 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10918 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10919 if the left or right operand symbols have the accuse flag set.
10921 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10923 Changed the type of the result of the ! (NOT) operator to char;
10924 previously it returned the same type as the source. This allows
10925 us to eliminate all the genFloatNot functions (all of its target
10926 implementations were very buggy) since !float can use the same
10929 * src/SDCCicode.c (ast2iCode): ! returns char

10938 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10939 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10940 during interrupts. Ensure WSAVE is located at a shared bank address.
10941 2. Fixed page selection in some places
10942 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10943 the registers name strings.
10944 4. Fixed "signed / unsigned compare" compiler warnings.
10945 5. The PIC port manages its own allocation of the general purpose
10946 registers, but makes no attempt to reuse them. As a result when
10947 compiling it soon runs out of general purpose registers. Some
10948 additional code was added to the files pcode.c and device.c to walk
10949 through the function call tree and rename the registers so that they
10959 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10960 genPlus() & genMinus() when the result is the same as left or right

10966 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10968 Made bitfield a distinct type from bit so that bitfields
10969 convert as per ANSI C and bits retain their traditional
10970 boolean style behaviour. Implemented bitfield support in
10978 * src/ds390/gen.c: bit v bitfield split
10979 * src/z80/gen.c: New support for bitfields

10990 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10992 Cleaned up genPackBits and genUnpackBits and added two helper
10993 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10994 for literal assignments in genPackBits (thanks to Frieder for
11000 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11002 Fixed bug #748310 (pointer to function type mishandled when the
11003 function name is omitted). Also fixed a SIGSEGV when a function
11004 attribute (reentrant, etc) is used on a non-function or on a
11005 function but misplaced before the parameter list.
11007 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

11032 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11034 Made the constant following the "interrupt" keyword optional. If
11035 omitted, the function will not automatically be given an entry
11036 in the interrupt vector table (similar to #pragma NOIV, but
11037 less syntacticly kludgy). The interrupt number is also now
11038 range checked. Also fixed a bug in the high order bit example

11514 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11515 the regression tests I'm not brave enough to enable 245.b, 245.c
11516 * doc/sdccman.lyx: added latex preamble for hyperref package.
11517 Using pdflatex this will give you a hyperlinked pdf file with
11518 bookmarks. (prepend '%' before /usepackage if this breaks something)
11520 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11568 added if/endif conditional macros to remove options help
11569 messages from optionsTable when a port is not configured, added
11570 support for the PIc16 port in the ports table, when executing
11571 the compiler with no port specified on command line, a default
11572 port is selected with the new macro DEFAULT_PORT which is
11573 defined in port.h, in setDefaultOptions() linkOptions is removed
11574 from initialization assignment, since now it is a set,
11575 parseCmdLine uses setParseWithComma for linkOptions, in
11576 linkEdit() linkOptions are accessed with new function indexSet()
11577 which returns the i'th item of a set variable. See SDCCset.c, in
11578 linkEdit() when calling buildCmdLine(), added linkOptions as
11579 last argument. Now users can pass arguments to gplink via the
11580 -Wl option, main() uses pic16glue() to glue up pic16 programs
11581 * src/SDCCpeeph.c: various changes to support pic16
11582 * src/SDCCset.c: added function void *indexSet(set *, int) to

11592 * src/pic16/glue.c: commented out some error producing lines
11593 * src/pic16/main.c: __config directives are commented out to stop
11594 gpasm complaining and test the linkage with gplink, _linkCmd and
11595 _asmCmd changed to be more gplink and gpasm friendly
11596 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11597 produced an error when parsed, peep rule 12 is added to utilize
11598 movff, but it is commented out since the pCode does not support
11599 yet a command with 2 address arguments
11601 2003-05-18 <johan AT balder>
11603 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12664 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12666 * in /sdcc/as/mcs51/ changed these files in order to create an
12667 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12668 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12669 following files to include the previous two files: aslink.dsp,
12670 Makefile.aslink, Makefile.bcc, and Makefile.in.
12672 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12673 .adb instead of .cdb
12675 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12677 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12678 value from option --iram-size.
12680 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12682 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12685 2002-09-18 <wiml AT hhhh.org>
12687 * SDCClrange.h: exposed setFromRange() and setToRange()
12688 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12689 packRegsForAccUse() (bug 542397)
12690 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12691 multiple times and emitting the fetch operations more than once
12692 added aopGetUsesAcc() function to allow binary operators to
12693 fetch their operands in the correct order; made genMinus() emit
12694 compact code for X = LITERAL - Y
12696 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12697 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12698 sprintf() in line 1267.
12700 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12701 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12704 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12705 Changes to aslink (All the changes are marked with 'JCF'):
12707 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12710 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12711 area BSEG. Also moves, if possible, the DATA area down into the internal
12712 ram so more space is available.
12714 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12717 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12718 not bytes. Function summary() which creates a memory usage summary
12719 file with extension .mem. Reports of overlaping stack and small stack
12720 size. If the space for the stack is less than 16 bytes aslink trows a
12723 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12724 the 8051. Option 'y' for memory summary output file.
12726 Changes to sdcc (All the changes are marked with 'JCF'):
12728 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12730 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12731 overlaying area for it (uses RegBankUsed[4]).
12733 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12734 bank zero as used by default. By default aslink locates the stack
12735 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12736 the creation of the .mem file. Delegates the allocation of data area
12737 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12738 the begining of the stack area to aslink.
12740 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12741 glue() in SDCCglue.c creates an area for it.
12743 2002-09-03 Borut Razem <borut.razem AT siol.net>
12744 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12745 sdcc/src/pic/glue.c:
12746 introduced atexit() handler for teporay files removal in case of
12747 errors, assertions, ...
12749 2002-08-29 Borut Razem <borut.razem AT siol.net>
12750 * sdcc/support/cpp2/auto-host_vc_in.h:
12751 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12752 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12753 Maybe there is a similar problem with BORLANDC? It should be checked!
12755 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12756 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12757 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12758 was not executed, and the compiler (cl) launched a warning:
12759 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12761 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12762 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12764 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

12772 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12773 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12774 - added Release configuration in VS projects
12775 - review of compiler an linker options
12776 - VC .exe files are generated in bin_vc directory, not to interfere
12777 with binaries generated from other projects (cygwin, mingw, bcc ...)
12779 * sdcc/src/yacc.dsp: added
12781 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12782 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12783 and insert the version number definitions from .version
12785 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12787 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12788 added - genarate auto-host.h using auto-host_vc_in.h as template
12791 removed from CVS, generated automatically
12793 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12794 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12796 2002-08-11 Borut Razem <borut.razem AT siol.net>
12797 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12799 2002-08-10 Borut Razem <borut.razem AT siol.net>
12800 * src/SDCCmain.c (main):
12801 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12802 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12803 The consequence was that some temporary files were not removed.
12806 unification of code in functions tempfilename() and tempfile():
12807 function tempnam() is defined in Visual Studio 6.0 and .NET
12809 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12811 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12812 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12813 - removed compiler command line option /WX: Treats all warnings as errors
12814 - update a list of source files, included into the project
12816 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12817 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12818 changed project type to Generic Project so that can be correcly converted to VS.NET project
12820 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12822 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12824 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12826 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12827 added return 0 statements after assert() to make compiler happy
12829 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12830 added newline in the def file to keep MSC compiler satisfied
12832 * sdcc/src/z80/gen.c:
12833 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12834 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12835 - solved MSC error in function aopDump()
12837 * sdcc_vc.h: define PREFIX as "\\sdcc"
12839 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12894 Compiler generated registers for interrupt context saving
12895 were not getting allocated.
12897 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12900 Fixed left shift. Will promote the left side of a left shift
12901 if a) left shifting more than size of operand or b) when assigned
12902 to something size > size of left side

13012 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13014 * sdcc/src/SDCCloop.c:
13015 Previous fix was not good. basic blocks that have "break" or "return" are
13016 not really partof a loop , but live ranges used in these blocks should
13017 be live thru the entire loop, so set partOfLoop but don't add them to
