2769 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2771 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2772 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2774 One basic decision: e.g. src/clean.mk includes further files. In order
2775 to make this work there are two solutions:
2776 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2777 run configure on them. This way they can use
2778 'include $(srcdir)/port-clean.mk'
2779 - always include clean.mk by the Makefile at the same level. To avoid
2780 that `make clean` tries to include and build Makefile.dep the
2781 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2782 implemented, because now even `make uninstall` doesn't create
2783 Makefile.in. clean.mk could be eliminated by pasting it in
2786 * debugger/mcs51/Makefile.in: build own objects from library sources
2787 (SLIB, SDCC) in current directory
2789 * configure, configure.in: renamed --disable-device-lib-build in
2790 --disable-device-lib; added --enable-doc, the required tools are
2791 searched by configure; added result message; the toolchain for the
2792 belonging ports are now only built, if the port is enabled.
2794 * support/regression/*: all output is written in directory gen, because
2795 the fwk and ports directories don't livet in the build tree using vpath
2797 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2798 --disable-device-lib, added --enable-doc, added section VPATH
2800 * sim/ucsim/configure.in,
2801 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2802 z80 are enabled by default
2804 2006-04-24 Raphael Neider <rneider AT web.de>
2806 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2807 to config word, "pic14_"-prefixed some extern functions
2808 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2809 config word has been found
2810 * src/pic/device.h: added prototypes
2811 * src/pic/pcode.c: added "pic14_"-prefix where needed
2812 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2814 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2828 fixes #1469504 and #1474602,
2829 (pCodeRegOptimizeRegUsage): fixed typo in comment

3052 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3054 * src/mcs51/gen.c (genCall): fixed bug 1457608
3056 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3058 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

3061 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3063 * src/SDCCpeeph.c (operandsLiteral): new, added,

3074 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3075 implemented patch 1120823 Thanks to Willy De la Court (normal
3076 interrupts need an interrupt number now if they are made critical),
3077 and enabled nesting of critical functions though not for gbz80
3078 (genCritical, genEndCritical): added functions
3079 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3080 * src/z80/mappings.i: added "ei" to all mappings
3082 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3084 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3085 submitted by the Debian SDCC maintainer Aurelien Jarno:
3086 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3087 archive with gcc 4.1 on mips and wrote the patch"
3089 2006-03-16 Raphael Neider <rneider AT web.de>
3091 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3092 the left operand is shorter than the result (c* = lit-c* + int),
3094 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3097 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3099 * src/.version: increased version number to 2.5.5
3100 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3101 linking is done manually in pic16 port's _linkEdit,
3102 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3103 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3104 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3105 allocate asmop as AOP_ACC,
3106 (aopForRemat): added parameter 'bool result' in function declaration,
3107 (pic16_aopGet): return AOP_ACC when accessing WREG,
3108 (pic16_popGetTempReg): minor modification,
3109 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3110 'pic16_allocWithIdx',
3111 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3112 calling function in absolute addresses,
3113 (genAssign): take into account AOP_ACC asmop,
3114 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3115 * src/pic16/pcoderegs.c: some debug functions and lines added,
3116 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3117 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3119 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3120 call to allocReg, not by manually allocating a new one,
3121 (pic16_assignRegisters): now before going through the register
3122 allocating functions mark all registers as free. This eliminates some
3123 side effects resulting from peephole parser done earlier in the backbone
3125 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3127 * src/SDCCicode.c (geniCodeLogic),

3145 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
3146 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3147 (aopForSym, aopOp): increment asmop.allocated if reused,
3148 (freeAsmop): decrement asmop.allocated and check for zero instead of
3150 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3151 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3152 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3175 2006-03-06 Borut Razem <borut.razem AT siol.net>
3177 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3178 made the linker quiet
3180 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3182 * src/pic16/gen.c (genPcall): fixed bug #1443644
3183 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3184 which dumps before the function entry point a data byte which represents
3185 the number of the local variables used by the specified function, added
3186 'xinst' for initial support for Extended Instruction Support,
3187 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3188 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3189 port->fun_prefix anymore (may change later),
3190 (genFunction, genEndFunction): do not store/restore local registers for
3191 _main (this should take care the --main-return command line option in
3193 (genOr): removed some legacy pic-port instructions,
3194 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3195 performing operations with SFR's causes data to be written more than
3196 once to each SFR. Perhaps SFRs should be handled in special cases...
3197 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3199 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3200 into account for stack starting position,
3201 (struct OPTIONS pic16_optionsTable): added command line argument
3202 --extended or -y for Extended Instruction Support,
3203 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3204 (deassignLRs): *** perhaps the most important change, old 'for' code
3205 (commented out for reference), didn't account for some registers which
3206 were left marked 'not free' after a pointer operation. The change
3207 reduces register usage a lot in some cases
3209 2006-03-04 Borut Razem <borut.razem AT siol.net>
3211 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5551 * device/lib/libsdcc.lib: added abs and labs
5552 * device/include/float.h,
5553 * device/lib/_fsmul.c,
5554 * device/lib/printf_fast.c,
5555 * device/lib/printf_tiny.c: updated comments
5557 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5559 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5562 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5564 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5565 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5567 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5569 * device/lib/printf_large.c: removed inline assembly for portability and
5570 readability. Use printf_fast if speed or size are more important.
5571 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5572 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5574 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5576 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5577 prevent compiler warning
5579 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5581 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5582 moved to level 0 and declared as static. Also they are explicit
5583 placed in access bank. This was necessery because some times they
5584 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5585 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5586 optimizations. Currently only compare to unsigned char is implemented,
5587 * src/pic16/gen.c: added fReturnIdx array,
5588 * (struct resolvedIfx) is moved to gen.h and made public,
5589 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5590 * (aopForSym): added an optimization to directly store in stack of
5591 the operand of a SEND iCode,
5592 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5593 but as registers instead (AOP_REG) using the fReturnIdx array,
5594 * (pic16_freeAsmop): remove the freed register from the
5595 _G.sregsAlloc field,
5596 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5597 a compare of 'WREG',
5598 * (pic16_popGetTempRegCond): changed function prototype, now
5599 function takes also a bitVector argument v which holds the current
5600 set of registers that are allocated for stack access by aopForSym,
5601 registers allocated in aopForSym for accessing stack symbols are not
5602 any more part of the functions usedRegs field,
5603 * (genCall): some times aopOp is called for a stack variable to be
5604 send, aopForSym might perform the push, if this is true make sure
5605 that genCall doesn't push the variable twice by testing _G.resDirect,
5606 * (genFunction): changed testing for unspecified interrupt number
5607 from 256 to INTNO_UNSPEC,
5608 * modified selection scheme of frame pointer generation. Previously
5609 if function did use local registers a frame pointer was generated,
5610 now a frame pointer is generated only if function has arguments
5611 (that need PLUSW2 register access), or has stack arguments, or the
5612 compiler is not instructed to omit the frame pointer,
5613 * (genEndFunction): before restoring local registers that were saved
5614 in the function preamble, also restore the registers that *might*
5615 have been allocated for stack access,
5616 * (genRet): removed some old comments,
5617 * (genCmp, the active (RN's) version): added a call to the
5618 pic16_genCmp_special function to perform the compare with a more
5619 robust and optimized way,
5620 * (genInline): a feature has been added in inline code generation,
5621 which allows a wildcard variable substitution when writing inline
5622 assembly. Code is incomplete and experimental therefore undocumented,
5623 * (genCast): changed order of aopOp for result and right to allow
5624 aopForSym to directly load the result if possible,
5625 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5626 perform an optimized compare on some selected special occasions,
5627 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5628 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5629 generate an IVT any more,
5630 * src/pic16/main.c (pic16_optionsTable): added command line option
5632 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5633 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5635 * src/pic16/NOTES: Raphael Neider added in list of active developers
5636 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5637 jumptable_end to prevent bug #,
5638 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5639 inCond and outCond fields,
5640 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5641 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5642 turn off register spilling,
5643 * (packRegsForOneUse): synced with other ports' versions although it
5644 is not used currently,
5645 * (pic16_packRegisters): added an optimization while reading
5646 structure bitfields, some registers may be saved (malloc code is
5647 decreased by 80 bytes)
5649 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5651 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5652 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5653 this can be optimized more?
5655 2005-03-10 Raphael Neider <rneider AT web.de>
5657 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5658 genNearPointerGet): (hopefully) fixed access to bitfields via
5659 pointers (p->bitN = x; and x = p->bitN; failed)
5661 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5702 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5704 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5705 to keep the correct label reference count when adding/removing references
5706 to labels. A peephole file using this is appended to patch #1144962.

5942 copy the third byte from the int -- now assumes 0x80 (data memory)
5943 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5944 operands (genAddLit expects the iCode's operands to swapped as

5983 * src/pic16/pcode.[ch]: introduced pic16_stackpnt_*,
5984 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
5985 access stack and frame pointers. They are initially assigned to

6294 generated for switch statements. For now you need to set the
6295 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6296 Now 4 algorithms for mcs51 jumptable generation are used:
6297 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

6329 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6331 * added libc directory. The current version of LibC contains string
6332 functions, ctype functions and macros and some functions of the
6333 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6334 be extensively tested in the future. Standard disclaimer here.

6347 * (pic16_storeForReturn): optimized return of 0,
6348 * (genCmp): experimental code for new genCmp which uses PIC18's
6349 special compare&skip instructions. Initial tests fail some times
6350 with variables grater than 1 byte in size, so new code is disabled,
6351 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6353 * (genCast): began a fix to optimize the casting of a bit to another
6354 bit, now assigning a bitfield to another bitfield will fail, sorry,

6368 registers when it shouldn't,
6369 * src/pic16/ralloc.c (allocReg): add preliminary support for
6370 supporting a limited set of temporary registers,
6372 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6378 (genFunction): optimize RECEIVE iCodes in reentrant functions
6380 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9379 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9380 loaded with the linker search paths (-L arguments) and the libraries
9381 to be linked with the current source (-l arguments). Changes
9382 currently will affect only the pic16 port.
9383 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9384 include path the port specific paths and port specific libraries,
9385 * gplink command now contains the $3 argument,
9386 * src/pic16/device.h,
9387 * src/pic16/device.c,: structure PIC_device is made public and
9388 renamed to PIC16_device, the same for variable Pics which is renamed

9403 Documenting changes from previous commits.
9404 * configure.in (version 1.56),
9405 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9406 when generating output files to configure the pic16 library,
9407 but now I've commented it out, since gputils aren't installed in the
9408 SF compile farm, so library won't compile
9410 * device/lib/Makefile.in (version 1.56): initially I've added in
9411 target 'all' the prerequestive 'model-pic16' so it compiled the
9412 pic16 library, but now I've commented it out for the same reasons
9414 * added targets 'model-pic16' and 'objects-pic16' to compile the
9416 * added target 'port-specific-objects-pic16' to handle the
9417 generated libraries and copy them into the build/ directory
9418 * added target 'clean-intermediate-pic16' to clean intermediate
9419 files into pic16 directory
9420 * in target 'installdirs' added line to create directory pic16 in
9421 the installation path

9424 added lines to copy all header files to installation path,
9425 * in target 'installdirs' added line create directory for pic16
9426 headers in the installation path

9442 option so that it actually works. Made it specific to the z80, since
9443 the gbz80 doesn't have these kinds of I/O ports.
9445 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9447 * device/include/z180.h,

9471 via literal number. The symbol is placed in the corresponding
9472 position of the data ram
9473 * (pic16_dump_section): relocatable and absolute uninitialized
9474 data are now emitted in sorted order to reduce section naming,
9475 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9476 weren't marked as being in the access bank,
9478 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9480 Added portion of GNU PIC Library under the directory
9481 device/include/pic16 and device/lib/pic16. These files
9482 contain the declarations of SFRs for the PIC18Fxx2 devices.
9483 The directory is initialized via configure from toplevel.

9513 all over. Telling LaTeX to be less strict with word spacing
9514 to better keep the right margin. Changed some notes about
9515 maintainance of the ports in section 3.2.1 - is it OK like this?
9517 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9553 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
9554 UPPER for immediate operands,
9555 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9557 * src/pic16/peeph.def: all peepholes with movff are commented out,
9558 because there is a problem in the pcode peep optimizer,
9559 * src/pic16/ralloc.c: the register allocator can now reuse local
9560 function symbols for another function. This saves register usage.

9669 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9671 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9672 (default behaviour).
9674 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9676 A python script to validate compiler diagnostic messages. It can be
9677 used to verify that sdcc complains about bad c source code and
9678 gives a good location of the error.
9679 * support/valdiag/Makefile,
9680 * support/valdiag/valdiag.py,
9681 * support/valdiag/tests/*

9700 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9702 * sdcc.spec: updated
9703 * device/include/Makefile.in: don't install CVS directories
9704 * device/lib/Makefile.in: added removal of CVS directories after install
9705 * doc/Makefile: fixed install, added local_icons
9706 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9707 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9708 * src/ds390/gen.c (genRightShift): fixed bug #870788
9709 * src/SDCCast.c (decorateType): fixed bug #870781
9711 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9713 PIC16 port related changes:
9714 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9715 added variable stackPos,
9717 * gen.c: genCall, assignResultValue: added support for
9718 pushing/retrieving function parameters to/from stack,
9719 genFunction,genEndFunction: setup stack frame for the
9721 genAddrOf: will be changed according to bug 863624
9723 * added files genutils.c and genutils.h which contain gen*
9724 debugged and optimised functions extracted from gen.c
9726 * glue.c: added variable 'externs' which holds extern symbols,
9727 pic16emitRegularMap: is modified to properly handle relocatable
9728 symbols under the new scheme,
9729 pic16createInterruptVect: is modified
9730 pic16printPublics: is modified to emit 'global' assembler directives,
9731 added pic16_printExterns to print extern symbols,
9732 pic16glue: initializes stack/frame pointer in the beginning of
9733 the assembly output. Temporary hack, will be corrected later,
9734 because gplink yet does not support stack and SDCC does not
9735 yet support a type of crt0.o object to create the final binary.
9737 * Removed many lines that contain 8051 legacy code.
9738 * The code is finally placed under a 'code' directive.
9739 * Added port specific options.
9741 * _process_pragma: simplified since now we do not need *special*
9742 include file to define SFR registers. But a separate header
9743 will be needed. This will be developed later.
9744 * _pic16_parseOptions: added, parses port specific options:
9745 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9746 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9747 --preplace-udata-with=
9749 * _pic16_setDefaultOptions: modified to initialize section names,
9750 but hack is temporarly out of order since it needs improvement.
9751 * _pic16_genAssemblerPreamble: configuration words are emitted by
9752 their address instead of their name. This part is incomplete and
9753 supports only the 18Fxx2 devices. Other devices will emit an error
9754 during assembly since they do not contain the same set of config
9756 * _pic16_genIVT: is modified,
9758 * pcode.c: added definitions for some hardware registers that are needed
9760 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9761 All PCI entries are updated. Now LFSR is supported.
9762 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9763 * added pic16_newpCodeOpLit2 to support instructions with
9764 two literal arguments
9765 * pic16_pCode2str: corrected code that emits assembler instructions
9766 with two literal operands and those that have an access bit modifier
9767 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9768 this fixes a bug which caused some labels to be lost, when an
9769 assembler directive was added, i.e. banksel,
9770 * pic16_FixRegisterBanking: improved logic that causes the insertion
9772 * InlineFunction: functions that are called once, are not any more
9773 inlined. This can be a port option in the future,
9775 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9777 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9778 hold the corresponding uninitialized symbols,
9779 * pic16_allocProcessorRegister: registers have explicit marked the
9781 * pic16_allocInternalRegister: registers are explicit marked as
9783 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9784 processing list, so bit registers were lost,
9787 * ralloc.h: added field 'accessBank' and original symbol operand
9788 in register definition,
9789 * removed the field isMapped from register definition,
9791 ** Several functions have been removed from various sources:
9792 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9793 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9794 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9795 pic16_assignRelocatableRegisters
9797 ** others have been introduced:
9798 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9799 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9801 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9803 * support/scripts/inc2h.pl: changed definition of BIT_AT
9804 to emit 'sbit at' instead of 'bit at'. This was a request.
9806 PIC16 port related preliminary changes:
9807 * gen.c: prefixed function popRegFromString with
9808 pic16_ and all references to it corrected
9809 * pcode.c: all pic16_pc_* hardware registers prefixed
9810 with underscore (_),
9811 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9812 * ralloc.c: newReg(): when register is REG_SFR then
9813 set address to rIdx,
9814 pic16_allocProcessorRegister(): marks register wasUsed=0
9815 pic16_writeUsedRegs(): added a call to assign processor
9816 registers via pic16_assignFixedRegisters
9818 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9820 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9821 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9822 variables in unused register banks. Also the SSEG is placed
9823 wherever there is enough space for it, and IDATA can be anywhere
9824 in internal RAM. For now compile using -Wl-Y[stack_size].
9825 The mem file is different for this option as well, since it
9826 makes no sense of talking about DSEG lenght.
9828 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9830 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9831 in certain cases, e.g. when ROM assignment, patch provided
9832 from Albert den Haan.
9834 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9977 * src/mcs51/peephole.def,
9978 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9979 (allows non-interrupt and interrupt code to safely compete for a resource

10719 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10720 support for standard C idiom of memory mapped variables; for
10721 example, *((xdata int*)0x1234) = 1 is now internally equivalent

10740 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10742 Fixed bug #621531 (const & volatile confusion in the type chain).
10743 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10744 refer to the const or volatile state of the pointer itself.

10823 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10824 iCode properly now. Use getSize instead of nRegs since a & b
10825 aren't part of the nRegs tally.
10827 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10829 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10841 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10842 If they pop r0/r1 they must be called in the opposite order than aopOp().
10843 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10844 (resp. --stack-auto), prepared for --xstack

10857 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10858 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10859 type for bits was changed. It resulted in bit variables becoming
10860 global, which is not permitted in PIC 14 assembly output.
10862 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10864 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10877 A few small changes that speed up the peephole optimizer.
10881 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10883 Try to make the peephole optimizer smarter by maintaining
10884 an association between the assembly source code and the
10885 iCodes that originated them. Put this information to use
10886 with a new peephole rule condition "notVolatile" so that
10887 the rules can be aggressive yet still safe.
10892 * src/mcs51/peeph.def
10894 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10898 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10899 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10900 if the left or right operand symbols have the accuse flag set.
10902 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10904 Changed the type of the result of the ! (NOT) operator to char;
10905 previously it returned the same type as the source. This allows
10906 us to eliminate all the genFloatNot functions (all of its target
10907 implementations were very buggy) since !float can use the same
10910 * src/SDCCicode.c (ast2iCode): ! returns char

10919 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10920 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10921 during interrupts. Ensure WSAVE is located at a shared bank address.
10922 2. Fixed page selection in some places
10923 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10924 the registers name strings.
10925 4. Fixed "signed / unsigned compare" compiler warnings.
10926 5. The PIC port manages its own allocation of the general purpose
10927 registers, but makes no attempt to reuse them. As a result when
10928 compiling it soon runs out of general purpose registers. Some
10929 additional code was added to the files pcode.c and device.c to walk
10930 through the function call tree and rename the registers so that they
10940 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10941 genPlus() & genMinus() when the result is the same as left or right

10947 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10949 Made bitfield a distinct type from bit so that bitfields
10950 convert as per ANSI C and bits retain their traditional
10951 boolean style behaviour. Implemented bitfield support in
10959 * src/ds390/gen.c: bit v bitfield split
10960 * src/z80/gen.c: New support for bitfields
10961 * support/regression/tests/bitfields.c: reenabled z80,
10964 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10966 Rules 246.x, 247.x relate to bitfields, the others speed up
10967 access to xdata mapped I/O devices.
10969 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10971 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10973 Cleaned up genPackBits and genUnpackBits and added two helper
10974 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10975 for literal assignments in genPackBits (thanks to Frieder for
10981 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10983 Fixed bug #748310 (pointer to function type mishandled when the
10984 function name is omitted). Also fixed a SIGSEGV when a function
10985 attribute (reentrant, etc) is used on a non-function or on a
10986 function but misplaced before the parameter list.
10988 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10990 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

11015 Made the constant following the "interrupt" keyword optional. If
11016 omitted, the function will not automatically be given an entry
11017 in the interrupt vector table (similar to #pragma NOIV, but
11018 less syntacticly kludgy). The interrupt number is also now
11019 range checked. Also fixed a bug in the high order bit example

11537 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
11539 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11540 it can be defined with CFLAGS when running configure
11541 * src/SDCCmain.c: fixed compiling + linking with object files
11543 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

11548 * src/SDCCmain.c: linkOptions is changed to set *,
11549 added if/endif conditional macros to remove options help
11550 messages from optionsTable when a port is not configured, added
11551 support for the PIc16 port in the ports table, when executing
11552 the compiler with no port specified on command line, a default
11553 port is selected with the new macro DEFAULT_PORT which is
11554 defined in port.h, in setDefaultOptions() linkOptions is removed
11555 from initialization assignment, since now it is a set,
11556 parseCmdLine uses setParseWithComma for linkOptions, in
11557 linkEdit() linkOptions are accessed with new function indexSet()
11558 which returns the i'th item of a set variable. See SDCCset.c, in
11559 linkEdit() when calling buildCmdLine(), added linkOptions as
11560 last argument. Now users can pass arguments to gplink via the
11561 -Wl option, main() uses pic16glue() to glue up pic16 programs
11562 * src/SDCCpeeph.c: various changes to support pic16
11563 * src/SDCCset.c: added function void *indexSet(set *, int) to

11573 * src/pic16/glue.c: commented out some error producing lines
11574 * src/pic16/main.c: __config directives are commented out to stop
11575 gpasm complaining and test the linkage with gplink, _linkCmd and
11576 _asmCmd changed to be more gplink and gpasm friendly
11577 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11578 produced an error when parsed, peep rule 12 is added to utilize
11579 movff, but it is commented out since the pCode does not support
11580 yet a command with 2 address arguments

12645 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12647 * in /sdcc/as/mcs51/ changed these files in order to create an
12648 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12649 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12650 following files to include the previous two files: aslink.dsp,
12651 Makefile.aslink, Makefile.bcc, and Makefile.in.
12653 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12654 .adb instead of .cdb
12656 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12658 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12659 value from option --iram-size.
12661 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12663 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12666 2002-09-18 <wiml AT hhhh.org>
12668 * SDCClrange.h: exposed setFromRange() and setToRange()
12669 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12670 packRegsForAccUse() (bug 542397)
12671 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12672 multiple times and emitting the fetch operations more than once
12673 added aopGetUsesAcc() function to allow binary operators to
12674 fetch their operands in the correct order; made genMinus() emit
12675 compact code for X = LITERAL - Y
12677 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12678 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12679 sprintf() in line 1267.
12681 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12682 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12685 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12686 Changes to aslink (All the changes are marked with 'JCF'):
12688 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12691 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12692 area BSEG. Also moves, if possible, the DATA area down into the internal
12693 ram so more space is available.
12695 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12698 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12699 not bytes. Function summary() which creates a memory usage summary
12700 file with extension .mem. Reports of overlaping stack and small stack
12701 size. If the space for the stack is less than 16 bytes aslink trows a
12704 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12705 the 8051. Option 'y' for memory summary output file.
12707 Changes to sdcc (All the changes are marked with 'JCF'):
12709 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12711 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12712 overlaying area for it (uses RegBankUsed[4]).
12714 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12715 bank zero as used by default. By default aslink locates the stack
12716 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12717 the creation of the .mem file. Delegates the allocation of data area
12718 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12719 the begining of the stack area to aslink.
12721 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12722 glue() in SDCCglue.c creates an area for it.
12724 2002-09-03 Borut Razem <borut.razem AT siol.net>
12725 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12726 sdcc/src/pic/glue.c:
12727 introduced atexit() handler for teporay files removal in case of
12728 errors, assertions, ...
12730 2002-08-29 Borut Razem <borut.razem AT siol.net>
12731 * sdcc/support/cpp2/auto-host_vc_in.h:
12732 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12733 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12734 Maybe there is a similar problem with BORLANDC? It should be checked!
12736 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12737 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12738 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12739 was not executed, and the compiler (cl) launched a warning:
12740 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12742 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12743 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

12755 - added Release configuration in VS projects
12756 - review of compiler an linker options
12757 - VC .exe files are generated in bin_vc directory, not to interfere
12758 with binaries generated from other projects (cygwin, mingw, bcc ...)
12760 * sdcc/src/yacc.dsp: added
12762 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12763 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12764 and insert the version number definitions from .version

12772 removed from CVS, generated automatically
12774 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12775 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12777 2002-08-11 Borut Razem <borut.razem AT siol.net>
12778 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12780 2002-08-10 Borut Razem <borut.razem AT siol.net>
12781 * src/SDCCmain.c (main):
12782 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12783 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12784 The consequence was that some temporary files were not removed.
12787 unification of code in functions tempfilename() and tempfile():
12788 function tempnam() is defined in Visual Studio 6.0 and .NET
12790 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12792 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12793 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12794 - removed compiler command line option /WX: Treats all warnings as errors
12795 - update a list of source files, included into the project
12797 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12798 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12799 changed project type to Generic Project so that can be correcly converted to VS.NET project
12801 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12803 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12805 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12807 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12808 added return 0 statements after assert() to make compiler happy
12810 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12811 added newline in the def file to keep MSC compiler satisfied
12813 * sdcc/src/z80/gen.c:
12814 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12815 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12816 - solved MSC error in function aopDump()
12818 * sdcc_vc.h: define PREFIX as "\\sdcc"
12820 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12995 * sdcc/src/SDCCloop.c:
12996 Previous fix was not good. basic blocks that have "break" or "return" are
12997 not really partof a loop , but live ranges used in these blocks should
