2793 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2795 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2796 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2798 One basic decision: e.g. src/clean.mk includes further files. In order
2799 to make this work there are two solutions:
2800 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2801 run configure on them. This way they can use
2802 'include $(srcdir)/port-clean.mk'
2803 - always include clean.mk by the Makefile at the same level. To avoid
2804 that `make clean` tries to include and build Makefile.dep the
2805 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2806 implemented, because now even `make uninstall` doesn't create
2807 Makefile.in. clean.mk could be eliminated by pasting it in
2810 * debugger/mcs51/Makefile.in: build own objects from library sources
2811 (SLIB, SDCC) in current directory
2813 * configure, configure.in: renamed --disable-device-lib-build in
2814 --disable-device-lib; added --enable-doc, the required tools are
2815 searched by configure; added result message; the toolchain for the
2816 belonging ports are now only built, if the port is enabled.
2818 * support/regression/*: all output is written in directory gen, because
2819 the fwk and ports directories don't livet in the build tree using vpath
2821 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2822 --disable-device-lib, added --enable-doc, added section VPATH
2824 * sim/ucsim/configure.in,
2825 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2826 z80 are enabled by default
2828 2006-04-24 Raphael Neider <rneider AT web.de>
2830 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2831 to config word, "pic14_"-prefixed some extern functions
2832 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2833 config word has been found
2834 * src/pic/device.h: added prototypes
2835 * src/pic/pcode.c: added "pic14_"-prefix where needed
2836 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2838 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2853 (pCodeRegOptimizeRegUsage): fixed typo in comment

3076 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3078 * src/mcs51/gen.c (genCall): fixed bug 1457608
3080 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3082 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

3085 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3087 * src/SDCCpeeph.c (operandsLiteral): new, added,

3099 implemented patch 1120823 Thanks to Willy De la Court (normal
3100 interrupts need an interrupt number now if they are made critical),
3101 and enabled nesting of critical functions though not for gbz80
3102 (genCritical, genEndCritical): added functions
3103 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3104 * src/z80/mappings.i: added "ei" to all mappings

3109 submitted by the Debian SDCC maintainer Aurelien Jarno:
3110 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3111 archive with gcc 4.1 on mips and wrote the patch"
3113 2006-03-16 Raphael Neider <rneider AT web.de>
3115 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3116 the left operand is shorter than the result (c* = lit-c* + int),
3118 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3121 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3123 * src/.version: increased version number to 2.5.5
3124 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3125 linking is done manually in pic16 port's _linkEdit,
3126 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3127 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3128 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3129 allocate asmop as AOP_ACC,
3130 (aopForRemat): added parameter 'bool result' in function declaration,
3131 (pic16_aopGet): return AOP_ACC when accessing WREG,
3132 (pic16_popGetTempReg): minor modification,
3133 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3134 'pic16_allocWithIdx',

3136 calling function in absolute addresses,
3137 (genAssign): take into account AOP_ACC asmop,

3141 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3143 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3144 call to allocReg, not by manually allocating a new one,
3145 (pic16_assignRegisters): now before going through the register
3146 allocating functions mark all registers as free. This eliminates some
3147 side effects resulting from peephole parser done earlier in the backbone
3149 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3151 * src/SDCCicode.c (geniCodeLogic),

3170 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3171 (aopForSym, aopOp): increment asmop.allocated if reused,
3172 (freeAsmop): decrement asmop.allocated and check for zero instead of
3174 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3175 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3176 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3199 2006-03-06 Borut Razem <borut.razem AT siol.net>
3201 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3202 made the linker quiet
3204 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3206 * src/pic16/gen.c (genPcall): fixed bug #1443644
3207 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3208 which dumps before the function entry point a data byte which represents
3209 the number of the local variables used by the specified function, added
3210 'xinst' for initial support for Extended Instruction Support,
3211 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3212 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3213 port->fun_prefix anymore (may change later),
3214 (genFunction, genEndFunction): do not store/restore local registers for
3215 _main (this should take care the --main-return command line option in
3217 (genOr): removed some legacy pic-port instructions,
3218 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3219 performing operations with SFR's causes data to be written more than
3220 once to each SFR. Perhaps SFRs should be handled in special cases...
3221 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3223 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3224 into account for stack starting position,
3225 (struct OPTIONS pic16_optionsTable): added command line argument
3226 --extended or -y for Extended Instruction Support,
3227 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3228 (deassignLRs): *** perhaps the most important change, old 'for' code
3229 (commented out for reference), didn't account for some registers which
3230 were left marked 'not free' after a pointer operation. The change
3231 reduces register usage a lot in some cases
3233 2006-03-04 Borut Razem <borut.razem AT siol.net>

5550 * src/SDCCdflow.c (computeDataFlow),
5552 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
5554 * src/SDCCcflow.c (*),
5556 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
5557 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5558 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5559 immedDom() returning wrong block; probably fixes bug #1160833)
5561 2005-03-20 Borut Razem <borut.razem AT siol.net>
5563 * support/scripts/inc2h.pl: WIN32 port
5565 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5567 * device/lib/makefile.in: added abs.c and labs.c
5569 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5571 * device/include/stdint.h: added
5572 * device/lib/abs.c: added
5573 * device/lib/labs.c: added
5574 * device/include/stdlib.h: added abs() and labs() prototypes
5575 * device/lib/libsdcc.lib: added abs and labs
5576 * device/include/float.h,
5577 * device/lib/_fsmul.c,
5578 * device/lib/printf_fast.c,
5579 * device/lib/printf_tiny.c: updated comments
5581 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5583 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5586 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5588 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5589 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5591 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5593 * device/lib/printf_large.c: removed inline assembly for portability and
5594 readability. Use printf_fast if speed or size are more important.
5595 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5596 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5598 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5600 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5601 prevent compiler warning
5603 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5605 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5606 moved to level 0 and declared as static. Also they are explicit
5607 placed in access bank. This was necessery because some times they
5608 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5609 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5610 optimizations. Currently only compare to unsigned char is implemented,
5611 * src/pic16/gen.c: added fReturnIdx array,
5612 * (struct resolvedIfx) is moved to gen.h and made public,
5613 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5614 * (aopForSym): added an optimization to directly store in stack of
5615 the operand of a SEND iCode,
5616 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5617 but as registers instead (AOP_REG) using the fReturnIdx array,
5618 * (pic16_freeAsmop): remove the freed register from the
5619 _G.sregsAlloc field,
5620 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5621 a compare of 'WREG',
5622 * (pic16_popGetTempRegCond): changed function prototype, now
5623 function takes also a bitVector argument v which holds the current
5624 set of registers that are allocated for stack access by aopForSym,
5625 registers allocated in aopForSym for accessing stack symbols are not
5626 any more part of the functions usedRegs field,
5627 * (genCall): some times aopOp is called for a stack variable to be
5628 send, aopForSym might perform the push, if this is true make sure
5629 that genCall doesn't push the variable twice by testing _G.resDirect,
5630 * (genFunction): changed testing for unspecified interrupt number
5631 from 256 to INTNO_UNSPEC,
5632 * modified selection scheme of frame pointer generation. Previously
5633 if function did use local registers a frame pointer was generated,
5634 now a frame pointer is generated only if function has arguments
5635 (that need PLUSW2 register access), or has stack arguments, or the
5636 compiler is not instructed to omit the frame pointer,
5637 * (genEndFunction): before restoring local registers that were saved
5638 in the function preamble, also restore the registers that *might*
5639 have been allocated for stack access,
5640 * (genRet): removed some old comments,
5641 * (genCmp, the active (RN's) version): added a call to the
5642 pic16_genCmp_special function to perform the compare with a more
5643 robust and optimized way,
5644 * (genInline): a feature has been added in inline code generation,
5645 which allows a wildcard variable substitution when writing inline
5646 assembly. Code is incomplete and experimental therefore undocumented,
5647 * (genCast): changed order of aopOp for result and right to allow
5648 aopForSym to directly load the result if possible,
5649 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5650 perform an optimized compare on some selected special occasions,
5651 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5652 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5653 generate an IVT any more,
5654 * src/pic16/main.c (pic16_optionsTable): added command line option
5656 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5657 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5659 * src/pic16/NOTES: Raphael Neider added in list of active developers
5660 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5661 jumptable_end to prevent bug #,
5662 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5663 inCond and outCond fields,
5664 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5665 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5666 turn off register spilling,
5667 * (packRegsForOneUse): synced with other ports' versions although it
5668 is not used currently,
5669 * (pic16_packRegisters): added an optimization while reading
5670 structure bitfields, some registers may be saved (malloc code is
5671 decreased by 80 bytes)
5673 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5675 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5676 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5677 this can be optimized more?
5679 2005-03-10 Raphael Neider <rneider AT web.de>
5681 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5682 genNearPointerGet): (hopefully) fixed access to bitfields via
5683 pointers (p->bitN = x; and x = p->bitN; failed)
5685 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5728 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5729 to keep the correct label reference count when adding/removing references
5730 to labels. A peephole file using this is appended to patch #1144962.

5873 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5874 this might fix SIGSEGVs on MinGW...

6317 Adding support for replacing ljmps with sjmps in jumptables
6318 generated for switch statements. For now you need to set the
6319 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6320 Now 4 algorithms for mcs51 jumptable generation are used:
6321 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

6353 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6355 * added libc directory. The current version of LibC contains string
6356 functions, ctype functions and macros and some functions of the
6357 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6358 be extensively tested in the future. Standard disclaimer here.
6359 Library is not automatically build yet. But one can build it by
6360 invoking 'make' inside the libc directory.

6371 * (pic16_storeForReturn): optimized return of 0,
6372 * (genCmp): experimental code for new genCmp which uses PIC18's
6373 special compare&skip instructions. Initial tests fail some times
6374 with variables grater than 1 byte in size, so new code is disabled,
6375 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6377 * (genCast): began a fix to optimize the casting of a bit to another
6378 bit, now assigning a bitfield to another bitfield will fail, sorry,

6386 * (isBankInstruction): modified to return 0 for no banking instruction,
6387 and 1 for banking instruction,
6388 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6389 caused stop processing pCodes after a inline assembly block,
6390 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6392 registers when it shouldn't,
6393 * src/pic16/ralloc.c (allocReg): add preliminary support for
6394 supporting a limited set of temporary registers,
6396 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6398 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

6402 (genFunction): optimize RECEIVE iCodes in reentrant functions
6404 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6406 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6415 * device/lib/_gptrget.c (_gptrget),
6416 * device/lib/_gptrgetc.c (_gptrgetc),

9401 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9403 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9404 loaded with the linker search paths (-L arguments) and the libraries
9405 to be linked with the current source (-l arguments). Changes
9406 currently will affect only the pic16 port.
9407 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9408 include path the port specific paths and port specific libraries,
9409 * gplink command now contains the $3 argument,
9410 * src/pic16/device.h,
9411 * src/pic16/device.c,: structure PIC_device is made public and
9412 renamed to PIC16_device, the same for variable Pics which is renamed

9427 Documenting changes from previous commits.
9428 * configure.in (version 1.56),
9429 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9430 when generating output files to configure the pic16 library,
9431 but now I've commented it out, since gputils aren't installed in the
9432 SF compile farm, so library won't compile
9434 * device/lib/Makefile.in (version 1.56): initially I've added in
9435 target 'all' the prerequestive 'model-pic16' so it compiled the
9436 pic16 library, but now I've commented it out for the same reasons
9438 * added targets 'model-pic16' and 'objects-pic16' to compile the
9440 * added target 'port-specific-objects-pic16' to handle the
9441 generated libraries and copy them into the build/ directory
9442 * added target 'clean-intermediate-pic16' to clean intermediate
9443 files into pic16 directory
9444 * in target 'installdirs' added line to create directory pic16 in
9445 the installation path

9448 added lines to copy all header files to installation path,
9449 * in target 'installdirs' added line create directory for pic16
9450 headers in the installation path

9466 option so that it actually works. Made it specific to the z80, since
9467 the gbz80 doesn't have these kinds of I/O ports.
9469 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9471 * device/include/z180.h,

9495 via literal number. The symbol is placed in the corresponding
9496 position of the data ram
9497 * (pic16_dump_section): relocatable and absolute uninitialized
9498 data are now emitted in sorted order to reduce section naming,
9499 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9500 weren't marked as being in the access bank,
9502 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9504 Added portion of GNU PIC Library under the directory
9505 device/include/pic16 and device/lib/pic16. These files
9506 contain the declarations of SFRs for the PIC18Fxx2 devices.
9507 The directory is initialized via configure from toplevel.

9536 * doc/sdccman.lyx: Moved and added some sections, small changes
9537 all over. Telling LaTeX to be less strict with word spacing
9538 to better keep the right margin. Changed some notes about
9539 maintainance of the ports in section 3.2.1 - is it OK like this?
9541 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9543 SDCC source changes:
9544 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9578 UPPER for immediate operands,
9579 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9581 * src/pic16/peeph.def: all peepholes with movff are commented out,
9582 because there is a problem in the pcode peep optimizer,
9583 * src/pic16/ralloc.c: the register allocator can now reuse local

9676 include information about variables allocated to the overlay
9679 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9681 * as/mcs51/lkmain.c: Help about -Y option

9693 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9695 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9696 (default behaviour).
9698 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9700 A python script to validate compiler diagnostic messages. It can be
9701 used to verify that sdcc complains about bad c source code and
9702 gives a good location of the error.
9703 * support/valdiag/Makefile,
9704 * support/valdiag/valdiag.py,
9705 * support/valdiag/tests/*
9707 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9720 * src/common.h: added ifndef/define/endif macros
9721 around the header file.
9722 Bug reported from Jesus Calvino-Fraga
9724 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9726 * sdcc.spec: updated
9727 * device/include/Makefile.in: don't install CVS directories
9728 * device/lib/Makefile.in: added removal of CVS directories after install
9729 * doc/Makefile: fixed install, added local_icons
9730 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9731 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9732 * src/ds390/gen.c (genRightShift): fixed bug #870788
9733 * src/SDCCast.c (decorateType): fixed bug #870781
9735 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9737 PIC16 port related changes:
9738 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9739 added variable stackPos,
9741 * gen.c: genCall, assignResultValue: added support for
9742 pushing/retrieving function parameters to/from stack,
9743 genFunction,genEndFunction: setup stack frame for the
9745 genAddrOf: will be changed according to bug 863624
9747 * added files genutils.c and genutils.h which contain gen*
9748 debugged and optimised functions extracted from gen.c
9750 * glue.c: added variable 'externs' which holds extern symbols,
9751 pic16emitRegularMap: is modified to properly handle relocatable
9752 symbols under the new scheme,
9753 pic16createInterruptVect: is modified
9754 pic16printPublics: is modified to emit 'global' assembler directives,
9755 added pic16_printExterns to print extern symbols,
9756 pic16glue: initializes stack/frame pointer in the beginning of
9757 the assembly output. Temporary hack, will be corrected later,
9758 because gplink yet does not support stack and SDCC does not
9759 yet support a type of crt0.o object to create the final binary.
9761 * Removed many lines that contain 8051 legacy code.
9762 * The code is finally placed under a 'code' directive.
9763 * Added port specific options.
9765 * _process_pragma: simplified since now we do not need *special*
9766 include file to define SFR registers. But a separate header
9767 will be needed. This will be developed later.
9768 * _pic16_parseOptions: added, parses port specific options:
9769 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9770 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9771 --preplace-udata-with=
9773 * _pic16_setDefaultOptions: modified to initialize section names,
9774 but hack is temporarly out of order since it needs improvement.
9775 * _pic16_genAssemblerPreamble: configuration words are emitted by
9776 their address instead of their name. This part is incomplete and
9777 supports only the 18Fxx2 devices. Other devices will emit an error
9778 during assembly since they do not contain the same set of config
9780 * _pic16_genIVT: is modified,
9782 * pcode.c: added definitions for some hardware registers that are needed
9784 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9785 All PCI entries are updated. Now LFSR is supported.
9786 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9787 * added pic16_newpCodeOpLit2 to support instructions with
9788 two literal arguments
9789 * pic16_pCode2str: corrected code that emits assembler instructions
9790 with two literal operands and those that have an access bit modifier
9791 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9792 this fixes a bug which caused some labels to be lost, when an
9793 assembler directive was added, i.e. banksel,
9794 * pic16_FixRegisterBanking: improved logic that causes the insertion
9796 * InlineFunction: functions that are called once, are not any more
9797 inlined. This can be a port option in the future,
9799 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9801 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9802 hold the corresponding uninitialized symbols,
9803 * pic16_allocProcessorRegister: registers have explicit marked the
9805 * pic16_allocInternalRegister: registers are explicit marked as
9807 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9808 processing list, so bit registers were lost,
9811 * ralloc.h: added field 'accessBank' and original symbol operand
9812 in register definition,
9813 * removed the field isMapped from register definition,
9815 ** Several functions have been removed from various sources:
9816 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9817 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9818 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9819 pic16_assignRelocatableRegisters
9821 ** others have been introduced:
9822 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9823 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9825 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9827 * support/scripts/inc2h.pl: changed definition of BIT_AT
9828 to emit 'sbit at' instead of 'bit at'. This was a request.
9830 PIC16 port related preliminary changes:
9831 * gen.c: prefixed function popRegFromString with
9832 pic16_ and all references to it corrected
9833 * pcode.c: all pic16_pc_* hardware registers prefixed
9834 with underscore (_),
9835 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9836 * ralloc.c: newReg(): when register is REG_SFR then
9837 set address to rIdx,
9838 pic16_allocProcessorRegister(): marks register wasUsed=0
9839 pic16_writeUsedRegs(): added a call to assign processor
9840 registers via pic16_assignFixedRegisters
9842 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9844 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9845 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9846 variables in unused register banks. Also the SSEG is placed
9847 wherever there is enough space for it, and IDATA can be anywhere
9848 in internal RAM. For now compile using -Wl-Y[stack_size].
9849 The mem file is different for this option as well, since it
9850 makes no sense of talking about DSEG lenght.
9852 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9854 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9855 in certain cases, e.g. when ROM assignment, patch provided
9856 from Albert den Haan.
9858 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10001 * src/mcs51/peephole.def,
10002 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
10003 (allows non-interrupt and interrupt code to safely compete for a resource

10743 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10744 support for standard C idiom of memory mapped variables; for
10745 example, *((xdata int*)0x1234) = 1 is now internally equivalent

10764 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10766 Fixed bug #621531 (const & volatile confusion in the type chain).
10767 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10768 refer to the const or volatile state of the pointer itself.

10863 copied from genNearPointerSet()
10864 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10865 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10866 If they pop r0/r1 they must be called in the opposite order than aopOp().
10867 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10868 (resp. --stack-auto), prepared for --xstack

10879 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10881 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10882 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10883 type for bits was changed. It resulted in bit variables becoming
10884 global, which is not permitted in PIC 14 assembly output.
10886 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10888 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10890 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10892 Z80 and MCS51 linkers complaint if a public symbol is defined

10899 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10901 A few small changes that speed up the peephole optimizer.
10905 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10907 Try to make the peephole optimizer smarter by maintaining
10908 an association between the assembly source code and the
10909 iCodes that originated them. Put this information to use
10910 with a new peephole rule condition "notVolatile" so that
10911 the rules can be aggressive yet still safe.
10916 * src/mcs51/peeph.def
10918 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10922 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10923 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10924 if the left or right operand symbols have the accuse flag set.
10926 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10928 Changed the type of the result of the ! (NOT) operator to char;
10929 previously it returned the same type as the source. This allows
10930 us to eliminate all the genFloatNot functions (all of its target
10931 implementations were very buggy) since !float can use the same
10934 * src/SDCCicode.c (ast2iCode): ! returns char

10943 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10944 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10945 during interrupts. Ensure WSAVE is located at a shared bank address.
10946 2. Fixed page selection in some places
10947 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10948 the registers name strings.
10949 4. Fixed "signed / unsigned compare" compiler warnings.
10950 5. The PIC port manages its own allocation of the general purpose
10951 registers, but makes no attempt to reuse them. As a result when
10952 compiling it soon runs out of general purpose registers. Some
10953 additional code was added to the files pcode.c and device.c to walk
10954 through the function call tree and rename the registers so that they
10964 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10965 genPlus() & genMinus() when the result is the same as left or right
10967 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10969 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
10971 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10973 Made bitfield a distinct type from bit so that bitfields
10974 convert as per ANSI C and bits retain their traditional
10975 boolean style behaviour. Implemented bitfield support in
10983 * src/ds390/gen.c: bit v bitfield split
10984 * src/z80/gen.c: New support for bitfields

10995 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10997 Cleaned up genPackBits and genUnpackBits and added two helper
10998 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10999 for literal assignments in genPackBits (thanks to Frieder for
11005 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11007 Fixed bug #748310 (pointer to function type mishandled when the
11008 function name is omitted). Also fixed a SIGSEGV when a function
11009 attribute (reentrant, etc) is used on a non-function or on a
11010 function but misplaced before the parameter list.
11012 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

11037 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11039 Made the constant following the "interrupt" keyword optional. If
11040 omitted, the function will not automatically be given an entry
11041 in the interrupt vector table (similar to #pragma NOIV, but
11042 less syntacticly kludgy). The interrupt number is also now
11043 range checked. Also fixed a bug in the high order bit example

11519 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11520 the regression tests I'm not brave enough to enable 245.b, 245.c
11521 * doc/sdccman.lyx: added latex preamble for hyperref package.
11522 Using pdflatex this will give you a hyperlinked pdf file with
11523 bookmarks. (prepend '%' before /usepackage if this breaks something)
11525 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11573 added if/endif conditional macros to remove options help
11574 messages from optionsTable when a port is not configured, added
11575 support for the PIc16 port in the ports table, when executing
11576 the compiler with no port specified on command line, a default
11577 port is selected with the new macro DEFAULT_PORT which is
11578 defined in port.h, in setDefaultOptions() linkOptions is removed
11579 from initialization assignment, since now it is a set,
11580 parseCmdLine uses setParseWithComma for linkOptions, in
11581 linkEdit() linkOptions are accessed with new function indexSet()
11582 which returns the i'th item of a set variable. See SDCCset.c, in
11583 linkEdit() when calling buildCmdLine(), added linkOptions as
11584 last argument. Now users can pass arguments to gplink via the
11585 -Wl option, main() uses pic16glue() to glue up pic16 programs

11597 * src/pic16/glue.c: commented out some error producing lines
11598 * src/pic16/main.c: __config directives are commented out to stop
11599 gpasm complaining and test the linkage with gplink, _linkCmd and
11600 _asmCmd changed to be more gplink and gpasm friendly
11601 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11602 produced an error when parsed, peep rule 12 is added to utilize
11603 movff, but it is commented out since the pCode does not support
11604 yet a command with 2 address arguments
11606 2003-05-18 <johan AT balder>
11608 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12669 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12671 * in /sdcc/as/mcs51/ changed these files in order to create an
12672 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12673 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12674 following files to include the previous two files: aslink.dsp,
12675 Makefile.aslink, Makefile.bcc, and Makefile.in.
12677 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12678 .adb instead of .cdb
12680 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12682 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12683 value from option --iram-size.
12685 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12687 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12690 2002-09-18 <wiml AT hhhh.org>
12692 * SDCClrange.h: exposed setFromRange() and setToRange()
12693 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12694 packRegsForAccUse() (bug 542397)
12695 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12696 multiple times and emitting the fetch operations more than once
12697 added aopGetUsesAcc() function to allow binary operators to
12698 fetch their operands in the correct order; made genMinus() emit
12699 compact code for X = LITERAL - Y
12701 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12702 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12703 sprintf() in line 1267.
12705 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12706 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12709 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12710 Changes to aslink (All the changes are marked with 'JCF'):
12712 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12715 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12716 area BSEG. Also moves, if possible, the DATA area down into the internal
12717 ram so more space is available.
12719 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12722 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12723 not bytes. Function summary() which creates a memory usage summary
12724 file with extension .mem. Reports of overlaping stack and small stack
12725 size. If the space for the stack is less than 16 bytes aslink trows a
12728 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12729 the 8051. Option 'y' for memory summary output file.
12731 Changes to sdcc (All the changes are marked with 'JCF'):
12733 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12735 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12736 overlaying area for it (uses RegBankUsed[4]).
12738 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12739 bank zero as used by default. By default aslink locates the stack
12740 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12741 the creation of the .mem file. Delegates the allocation of data area
12742 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12743 the begining of the stack area to aslink.
12745 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12746 glue() in SDCCglue.c creates an area for it.
12748 2002-09-03 Borut Razem <borut.razem AT siol.net>
12749 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12750 sdcc/src/pic/glue.c:
12751 introduced atexit() handler for teporay files removal in case of
12752 errors, assertions, ...
12754 2002-08-29 Borut Razem <borut.razem AT siol.net>
12755 * sdcc/support/cpp2/auto-host_vc_in.h:
12756 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12757 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12758 Maybe there is a similar problem with BORLANDC? It should be checked!
12760 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12761 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12762 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12763 was not executed, and the compiler (cl) launched a warning:
12764 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12766 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12767 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12769 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

12777 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12778 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12779 - added Release configuration in VS projects
12780 - review of compiler an linker options
12781 - VC .exe files are generated in bin_vc directory, not to interfere
12782 with binaries generated from other projects (cygwin, mingw, bcc ...)
12784 * sdcc/src/yacc.dsp: added
12786 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12787 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12788 and insert the version number definitions from .version
12790 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12792 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12793 added - genarate auto-host.h using auto-host_vc_in.h as template
12796 removed from CVS, generated automatically
12798 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12799 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12801 2002-08-11 Borut Razem <borut.razem AT siol.net>
12802 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12804 2002-08-10 Borut Razem <borut.razem AT siol.net>
12805 * src/SDCCmain.c (main):
12806 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12807 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12808 The consequence was that some temporary files were not removed.
12811 unification of code in functions tempfilename() and tempfile():
12812 function tempnam() is defined in Visual Studio 6.0 and .NET
12814 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12816 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12817 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12818 - removed compiler command line option /WX: Treats all warnings as errors
12819 - update a list of source files, included into the project
12821 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12822 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12823 changed project type to Generic Project so that can be correcly converted to VS.NET project
12825 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12827 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12831 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12832 added return 0 statements after assert() to make compiler happy
12834 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12835 added newline in the def file to keep MSC compiler satisfied
12837 * sdcc/src/z80/gen.c:
12838 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12839 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12840 - solved MSC error in function aopDump()
12842 * sdcc_vc.h: define PREFIX as "\\sdcc"
12844 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12899 Compiler generated registers for interrupt context saving
12900 were not getting allocated.
12902 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

13017 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13019 * sdcc/src/SDCCloop.c:
13020 Previous fix was not good. basic blocks that have "break" or "return" are
13021 not really partof a loop , but live ranges used in these blocks should
13022 be live thru the entire loop, so set partOfLoop but don't add them to
