11 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
13 Enabled VPATH feature: changed nearly all Makefiles (149 files).
14 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
16 One basic decision: e.g. src/clean.mk includes further files. In order
17 to make this work there are two solutions:
18 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
19 run configure on them. This way they can use
20 'include $(srcdir)/port-clean.mk'
21 - always include clean.mk by the Makefile at the same level. To avoid
22 that `make clean` tries to include and build Makefile.dep the
23 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
24 implemented, because now even `make uninstall` doesn't create
25 Makefile.in. clean.mk could be eliminated by pasting it in
28 * debugger/mcs51/Makefile.in: build own objects from library sources
29 (SLIB, SDCC) in current directory
31 * configure, configure.in: renamed --disable-device-lib-build in
32 --disable-device-lib; added --enable-doc, the required tools are
33 searched by configure; added result message; the toolchain for the
34 belonging ports are now only built, if the port is enabled.
36 * support/regression/*: all output is written in directory gen, because
37 the fwk and ports directories don't livet in the build tree using vpath
39 * doc/sdccman.lyx: renamed --disable-device-lib-build to
40 --disable-device-lib, added --enable-doc, added section VPATH
42 * sim/ucsim/configure.in,
43 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
44 z80 are enabled by default
46 2006-04-24 Raphael Neider <rneider AT web.de>
48 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
49 config word, "pic14_"-prefixed some extern functions

51 config word has been found
52 * src/pic/device.h: added prototypes
53 * src/pic/pcode.c: added "pic14_"-prefix where needed
54 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic fixup

314 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
315 implemented patch 1120823 Thanks to Willy De la Court (normal

317 and enabled nesting of critical functions though not for gbz80
318 (genCritical, genEndCritical): added functions
319 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
320 * src/z80/mappings.i: added "ei" to all mappings

325 submitted by the Debian SDCC maintainer Aurelien Jarno:
326 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
327 archive with gcc 4.1 on mips and wrote the patch"
329 2006-03-16 Raphael Neider <rneider AT web.de>
331 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
332 the left operand is shorter than the result (c* = lit-c* + int),
334 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
337 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
339 * src/.version: increased version number to 2.5.5
340 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
341 linking is done manually in pic16 port's _linkEdit,
342 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
343 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
344 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
345 allocate asmop as AOP_ACC,
346 (aopForRemat): added parameter 'bool result' in function declaration,

359 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
360 call to allocReg, not by manually allocating a new one,
361 (pic16_assignRegisters): now before going through the register
362 allocating functions mark all registers as free. This eliminates some
363 side effects resulting from peephole parser done earlier in the backbone
365 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
367 * src/SDCCicode.c (geniCodeLogic),

412 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
413 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
415 2006-03-06 Borut Razem <borut.razem AT siol.net>
417 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
418 made the linker quiet
420 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
422 * src/pic16/gen.c (genPcall): fixed bug #1443644
423 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
424 which dumps before the function entry point a data byte which represents
425 the number of the local variables used by the specified function, added
426 'xinst' for initial support for Extended Instruction Support,
427 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
428 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
429 port->fun_prefix anymore (may change later),
430 (genFunction, genEndFunction): do not store/restore local registers for
431 _main (this should take care the --main-return command line option in
433 (genOr): removed some legacy pic-port instructions,
434 * src/pic16/genarith.c (genAddLit): re-enabled old code because
435 performing operations with SFR's causes data to be written more than
436 once to each SFR. Perhaps SFRs should be handled in special cases...
437 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
439 * src/pic16/main.c (_process_pragma): stack bound checking did not take
440 into account for stack starting position,
441 (struct OPTIONS pic16_optionsTable): added command line argument
442 --extended or -y for Extended Instruction Support,
443 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
444 (deassignLRs): *** perhaps the most important change, old 'for' code
445 (commented out for reference), didn't account for some registers which
446 were left marked 'not free' after a pointer operation. The change
447 reduces register usage a lot in some cases
449 2006-03-04 Borut Razem <borut.razem AT siol.net>

2722 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2723 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2724 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2725 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2726 always available in leading double underscore form. The C99 support is
2727 mostly missing, but it's a start.
2728 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2729 reserved identifier "__data".

2785 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2787 * device/include/stdint.h: added
2788 * device/lib/abs.c: added

2807 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2809 * device/lib/printf_large.c: removed inline assembly for portability and
2810 readability. Use printf_fast if speed or size are more important.
2811 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2812 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2814 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2816 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2817 prevent compiler warning
2819 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2821 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2822 moved to level 0 and declared as static. Also they are explicit
2823 placed in access bank. This was necessery because some times they
2824 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2825 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2826 optimizations. Currently only compare to unsigned char is implemented,
2827 * src/pic16/gen.c: added fReturnIdx array,
2828 * (struct resolvedIfx) is moved to gen.h and made public,
2829 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2830 * (aopForSym): added an optimization to directly store in stack of
2831 the operand of a SEND iCode,
2832 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2833 but as registers instead (AOP_REG) using the fReturnIdx array,
2834 * (pic16_freeAsmop): remove the freed register from the
2835 _G.sregsAlloc field,
2836 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2837 a compare of 'WREG',
2838 * (pic16_popGetTempRegCond): changed function prototype, now
2839 function takes also a bitVector argument v which holds the current
2840 set of registers that are allocated for stack access by aopForSym,
2841 registers allocated in aopForSym for accessing stack symbols are not
2842 any more part of the functions usedRegs field,
2843 * (genCall): some times aopOp is called for a stack variable to be
2844 send, aopForSym might perform the push, if this is true make sure
2845 that genCall doesn't push the variable twice by testing _G.resDirect,
2846 * (genFunction): changed testing for unspecified interrupt number
2847 from 256 to INTNO_UNSPEC,
2848 * modified selection scheme of frame pointer generation. Previously
2849 if function did use local registers a frame pointer was generated,
2850 now a frame pointer is generated only if function has arguments
2851 (that need PLUSW2 register access), or has stack arguments, or the
2852 compiler is not instructed to omit the frame pointer,
2853 * (genEndFunction): before restoring local registers that were saved
2854 in the function preamble, also restore the registers that *might*
2855 have been allocated for stack access,
2856 * (genRet): removed some old comments,
2857 * (genCmp, the active (RN's) version): added a call to the
2858 pic16_genCmp_special function to perform the compare with a more
2859 robust and optimized way,
2860 * (genInline): a feature has been added in inline code generation,
2861 which allows a wildcard variable substitution when writing inline
2862 assembly. Code is incomplete and experimental therefore undocumented,
2863 * (genCast): changed order of aopOp for result and right to allow
2864 aopForSym to directly load the result if possible,
2865 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2866 perform an optimized compare on some selected special occasions,
2867 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2868 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2869 generate an IVT any more,
2870 * src/pic16/main.c (pic16_optionsTable): added command line option
2872 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2873 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2875 * src/pic16/NOTES: Raphael Neider added in list of active developers
2876 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2877 jumptable_end to prevent bug #,
2878 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2879 inCond and outCond fields,
2880 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2881 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2882 turn off register spilling,
2883 * (packRegsForOneUse): synced with other ports' versions although it
2884 is not used currently,
2885 * (pic16_packRegisters): added an optimization while reading
2886 structure bitfields, some registers may be saved (malloc code is
2887 decreased by 80 bytes)
2889 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2891 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2892 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2893 this can be optimized more?
2895 2005-03-10 Raphael Neider <rneider AT web.de>
2897 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2898 genNearPointerGet): (hopefully) fixed access to bitfields via
2899 pointers (p->bitN = x; and x = p->bitN; failed)
2901 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3533 Adding support for replacing ljmps with sjmps in jumptables
3534 generated for switch statements. For now you need to set the
3535 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3536 Now 4 algorithms for mcs51 jumptable generation are used:
3537 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3538 addresses loaded pc-relative for up to 112 cases and stack-pushing
3539 target addresses loaded with offset from dptr for up to 256 cases.

3566 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3567 to call when a stack overflow occurs,
3568 * (malloc.h): added CVS Id tag,
3569 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3571 * added libc directory. The current version of LibC contains string
3572 functions, ctype functions and macros and some functions of the
3573 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3574 be extensively tested in the future. Standard disclaimer here.
3575 Library is not automatically build yet. But one can build it by
3576 invoking 'make' inside the libc directory.
3577 * added ADC library under libio. Preliminary version yet.

3583 temporary registers, its a buggy feature and will be removed,
3584 * (pic16_popGet): set register instance field in AOP_CRY,
3585 * (pic16_outBitC): fixed for results in size greater than 1,
3586 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3587 * (pic16_storeForReturn): optimized return of 0,
3588 * (genCmp): experimental code for new genCmp which uses PIC18's
3589 special compare&skip instructions. Initial tests fail some times
3590 with variables grater than 1 byte in size, so new code is disabled,
3591 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3593 * (genCast): began a fix to optimize the casting of a bit to another
3594 bit, now assigning a bitfield to another bitfield will fail, sorry,
3595 * src/pic16/main.c: disabled the use of lr-support feature,
3596 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3599 bits with offset (case PO_GPR_BIT),
3600 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3602 * (isBankInstruction): modified to return 0 for no banking instruction,
3603 and 1 for banking instruction,
3604 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3605 caused stop processing pCodes after a inline assembly block,
3606 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3607 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3608 registers when it shouldn't,
3609 * src/pic16/ralloc.c (allocReg): add preliminary support for
3610 supporting a limited set of temporary registers,
3612 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3614 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3615 genDataPointerSet): ensure assignments always copy in MSB to LSB
3617 (loadRegFromAop): recognize CLRH optimization,
3618 (genFunction): optimize RECEIVE iCodes in reentrant functions
3620 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6549 * src/pic/glue (pic14emitRegularMap),
6550 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6552 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6554 * src/pic/pcode.c (PCodeID): commented out left over debug code
6556 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6558 * support/valdiag/tests/overflow.c: added shift tests
6566 * src/pic/pcodepeep.c,
6567 * src/pic/pcoderegs.c,
6569 * src/pic/ralloc.h: applied patch from Slade Rich;
6570 added support for multiple code pages and multiple RAM banks on the
6571 PIC 14 port. The ASM files now no longer simply assume all the
6572 code / RAM are in the same page / bank. This means the linker can
6573 safely allocate code/RAM of separate ASM files to different pages/banks.
6574 * doc/sdccman.lyx: added Slade's tips
6575 * src/mcs51/peeph.def: fixed bug #880768

6584 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6587 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6588 strtof is not part of C89 and isn't included with Mac OS X.
6590 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6592 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6617 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6619 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6620 loaded with the linker search paths (-L arguments) and the libraries
6621 to be linked with the current source (-l arguments). Changes
6622 currently will affect only the pic16 port.
6623 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6624 include path the port specific paths and port specific libraries,
6625 * gplink command now contains the $3 argument,
6626 * src/pic16/device.h,
6627 * src/pic16/device.c,: structure PIC_device is made public and
6628 renamed to PIC16_device, the same for variable Pics which is renamed
6629 to Pics16. Updated all references to them.
6630 * src/pic16/glue.c (pic16glue): corrected bug with code
6631 initialization which bypassed the variable initializations block.

6641 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6643 Documenting changes from previous commits.
6644 * configure.in (version 1.56),
6645 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6646 when generating output files to configure the pic16 library,
6647 but now I've commented it out, since gputils aren't installed in the
6648 SF compile farm, so library won't compile
6650 * device/lib/Makefile.in (version 1.56): initially I've added in
6651 target 'all' the prerequestive 'model-pic16' so it compiled the
6652 pic16 library, but now I've commented it out for the same reasons
6654 * added targets 'model-pic16' and 'objects-pic16' to compile the
6656 * added target 'port-specific-objects-pic16' to handle the
6657 generated libraries and copy them into the build/ directory
6658 * added target 'clean-intermediate-pic16' to clean intermediate
6659 files into pic16 directory
6660 * in target 'installdirs' added line to create directory pic16 in
6661 the installation path
6663 * device/include/Makefile.in (version 1.11): in target 'install'
6664 added lines to copy all header files to installation path,
6665 * in target 'installdirs' added line create directory for pic16
6666 headers in the installation path

6681 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6682 option so that it actually works. Made it specific to the z80, since
6683 the gbz80 doesn't have these kinds of I/O ports.
6685 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6687 * device/include/z180.h,

6709 Mainly changes to support compilation of the device libraries
6710 * src/pic16/device.c: stack is allocated via symbol and not
6711 via literal number. The symbol is placed in the corresponding
6712 position of the data ram
6713 * (pic16_dump_section): relocatable and absolute uninitialized
6714 data are now emitted in sorted order to reduce section naming,
6715 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6716 weren't marked as being in the access bank,
6718 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6720 Added portion of GNU PIC Library under the directory
6721 device/include/pic16 and device/lib/pic16. These files
6722 contain the declarations of SFRs for the PIC18Fxx2 devices.
6723 The directory is initialized via configure from toplevel.
6725 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6727 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6739 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6741 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6742 in simpler and even better code

6753 all over. Telling LaTeX to be less strict with word spacing
6754 to better keep the right margin. Changed some notes about
6755 maintainance of the ports in section 3.2.1 - is it OK like this?
6757 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6795 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6797 * src/pic16/peeph.def: all peepholes with movff are commented out,
6798 because there is a problem in the pcode peep optimizer,
6799 * src/pic16/ralloc.c: the register allocator can now reuse local

6951 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6953 PIC16 port related changes:
6954 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6955 added variable stackPos,
6957 * gen.c: genCall, assignResultValue: added support for
6958 pushing/retrieving function parameters to/from stack,
6959 genFunction,genEndFunction: setup stack frame for the
6961 genAddrOf: will be changed according to bug 863624
6963 * added files genutils.c and genutils.h which contain gen*
6964 debugged and optimised functions extracted from gen.c
6966 * glue.c: added variable 'externs' which holds extern symbols,
6967 pic16emitRegularMap: is modified to properly handle relocatable
6968 symbols under the new scheme,
6969 pic16createInterruptVect: is modified
6970 pic16printPublics: is modified to emit 'global' assembler directives,
6971 added pic16_printExterns to print extern symbols,
6972 pic16glue: initializes stack/frame pointer in the beginning of
6973 the assembly output. Temporary hack, will be corrected later,
6974 because gplink yet does not support stack and SDCC does not
6975 yet support a type of crt0.o object to create the final binary.
6977 * Removed many lines that contain 8051 legacy code.
6978 * The code is finally placed under a 'code' directive.
6979 * Added port specific options.
6981 * _process_pragma: simplified since now we do not need *special*
6982 include file to define SFR registers. But a separate header
6983 will be needed. This will be developed later.
6984 * _pic16_parseOptions: added, parses port specific options:
6985 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6986 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6987 --preplace-udata-with=
6989 * _pic16_setDefaultOptions: modified to initialize section names,
6990 but hack is temporarly out of order since it needs improvement.
6991 * _pic16_genAssemblerPreamble: configuration words are emitted by
6992 their address instead of their name. This part is incomplete and
6993 supports only the 18Fxx2 devices. Other devices will emit an error
6994 during assembly since they do not contain the same set of config
6996 * _pic16_genIVT: is modified,
6998 * pcode.c: added definitions for some hardware registers that are needed
7000 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7001 All PCI entries are updated. Now LFSR is supported.
7002 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7003 * added pic16_newpCodeOpLit2 to support instructions with
7004 two literal arguments
7005 * pic16_pCode2str: corrected code that emits assembler instructions
7006 with two literal operands and those that have an access bit modifier
7007 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7008 this fixes a bug which caused some labels to be lost, when an
7009 assembler directive was added, i.e. banksel,
7010 * pic16_FixRegisterBanking: improved logic that causes the insertion
7012 * InlineFunction: functions that are called once, are not any more
7013 inlined. This can be a port option in the future,
7015 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7017 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7018 hold the corresponding uninitialized symbols,
7019 * pic16_allocProcessorRegister: registers have explicit marked the
7021 * pic16_allocInternalRegister: registers are explicit marked as
7023 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7024 processing list, so bit registers were lost,
7027 * ralloc.h: added field 'accessBank' and original symbol operand
7028 in register definition,
7029 * removed the field isMapped from register definition,
7031 ** Several functions have been removed from various sources:
7032 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7033 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7034 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7035 pic16_assignRelocatableRegisters
7037 ** others have been introduced:
7038 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7039 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7041 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7043 * support/scripts/inc2h.pl: changed definition of BIT_AT
7044 to emit 'sbit at' instead of 'bit at'. This was a request.
7046 PIC16 port related preliminary changes:
7047 * gen.c: prefixed function popRegFromString with
7048 pic16_ and all references to it corrected
7049 * pcode.c: all pic16_pc_* hardware registers prefixed
7050 with underscore (_),
7051 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7052 * ralloc.c: newReg(): when register is REG_SFR then
7053 set address to rIdx,
7054 pic16_allocProcessorRegister(): marks register wasUsed=0
7055 pic16_writeUsedRegs(): added a call to assign processor
7056 registers via pic16_assignFixedRegisters
7058 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7060 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7061 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7062 variables in unused register banks. Also the SSEG is placed
7063 wherever there is enough space for it, and IDATA can be anywhere
7064 in internal RAM. For now compile using -Wl-Y[stack_size].
7065 The mem file is different for this option as well, since it
7066 makes no sense of talking about DSEG lenght.
7068 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7070 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7315 * src/SDCCast.c (decorateType): disabled a transformation I added in
7316 revision 1.188 (access to fields of a structure at an absolute address);
7317 it breaks with bitfields, extern declarations, and gcse analysis.
7318 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7319 could be assigned through a pointer, so don't complain.

8043 reported in bug #800609
8045 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8047 * Top header beautifications in src/pic16 directory:
8048 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8049 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8050 pcoderegs.h, ralloc.c, ralloc.h
8051 * main.c: added top header and GPL license notice
8052 * pcode.c: fixed the if-conditional warning
8054 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8056 * device/lib/_mullong.c: replaced int by short for gcc
8058 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8060 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8061 and JUMPTABLE iCodes properly now (worked by accident before)
8062 * src/mcs51/gen.c (leftRightUseAcc),
8063 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8064 iCode properly now. Use getSize instead of nRegs since a & b
8065 aren't part of the nRegs tally.
8067 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8069 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8070 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8071 before instructions that use the _STATUS register
8073 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8075 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8076 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8077 fetching of the pointer
8078 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8079 copied from genNearPointerSet()
8080 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8081 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8082 If they pop r0/r1 they must be called in the opposite order than aopOp().
8083 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8084 (resp. --stack-auto), prepared for --xstack
8086 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8090 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8092 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8093 these ports have their own __sdcc_external_start()
8095 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8097 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8098 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8099 type for bits was changed. It resulted in bit variables becoming
8100 global, which is not permitted in PIC 14 assembly output.
8102 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8104 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8106 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8108 Z80 and MCS51 linkers complaint if a public symbol is defined
8109 in more than one library module:
8113 * as/mcs51/Makefile.in
8115 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8117 A few small changes that speed up the peephole optimizer.
8121 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8123 Try to make the peephole optimizer smarter by maintaining
8124 an association between the assembly source code and the
8125 iCodes that originated them. Put this information to use
8126 with a new peephole rule condition "notVolatile" so that
8127 the rules can be aggressive yet still safe.
8132 * src/mcs51/peeph.def
8134 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8138 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8139 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8140 if the left or right operand symbols have the accuse flag set.
8142 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8144 Changed the type of the result of the ! (NOT) operator to char;
8145 previously it returned the same type as the source. This allows
8146 us to eliminate all the genFloatNot functions (all of its target
8147 implementations were very buggy) since !float can use the same
8150 * src/SDCCicode.c (ast2iCode): ! returns char
8151 * src/mcs51/gen.c (genNot, genNotFloat),
8152 * src/ds390/gen.c (genNot, genNotFloat),
8153 * src/z80/gen.c (genNot, genNotFloat),
8154 * src/pic/gen.c (genNot, genNotFloat),
8155 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8157 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8159 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8160 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8161 during interrupts. Ensure WSAVE is located at a shared bank address.
8162 2. Fixed page selection in some places
8163 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8164 the registers name strings.
8165 4. Fixed "signed / unsigned compare" compiler warnings.
8166 5. The PIC port manages its own allocation of the general purpose
8167 registers, but makes no attempt to reuse them. As a result when
8168 compiling it soon runs out of general purpose registers. Some
8169 additional code was added to the files pcode.c and device.c to walk
8170 through the function call tree and rename the registers so that they
8180 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8181 genPlus() & genMinus() when the result is the same as left or right

8187 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8189 Made bitfield a distinct type from bit so that bitfields
8190 convert as per ANSI C and bits retain their traditional
8191 boolean style behaviour. Implemented bitfield support in
8199 * src/ds390/gen.c: bit v bitfield split
8200 * src/z80/gen.c: New support for bitfields
8201 * support/regression/tests/bitfields.c: reenabled z80,
8204 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8206 Rules 246.x, 247.x relate to bitfields, the others speed up
8207 access to xdata mapped I/O devices.
8209 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8211 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8213 Cleaned up genPackBits and genUnpackBits and added two helper
8214 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8215 for literal assignments in genPackBits (thanks to Frieder for
8221 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8223 Fixed bug #748310 (pointer to function type mishandled when the
8224 function name is omitted). Also fixed a SIGSEGV when a function
8225 attribute (reentrant, etc) is used on a non-function or on a
8226 function but misplaced before the parameter list.
8228 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8230 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8231 * support/Util/SDCCerr.h,
8232 * support/Util/SDCCerr.c: Added func attr misuse error msg
8234 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8236 Fixed bug #787649 by anonymous
8237 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8253 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8255 Made the constant following the "interrupt" keyword optional. If
8256 omitted, the function will not automatically be given an entry
8257 in the interrupt vector table (similar to #pragma NOIV, but
8258 less syntacticly kludgy). The interrupt number is also now
8259 range checked. Also fixed a bug in the high order bit example
8266 * support/Util/SDCCerr.c
8267 * support/Util/SDCCerr.h
8270 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8272 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8273 * src/SDCCicode.c (operandOperation): rewritten some ops
8274 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8275 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8277 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8278 be re-activated by defining REDUCE_LITERALS)
8279 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8280 unsigned, but are signed by default
8281 * src/SDCCval.c (constVal): rearranged
8282 * src/SDCCval.c (valMod): preliminary fix
8283 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8326 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8327 * src/SDCCval.c (valDiv, valMod): fixed signdness
8328 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8329 signedness of modulo, left and right shift

8735 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8736 the regression tests I'm not brave enough to enable 245.b, 245.c
8737 * doc/sdccman.lyx: added latex preamble for hyperref package.
8738 Using pdflatex this will give you a hyperlinked pdf file with
8739 bookmarks. (prepend '%' before /usepackage if this breaks something)

8777 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8779 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8780 it can be defined with CFLAGS when running configure
8781 * src/SDCCmain.c: fixed compiling + linking with object files
8783 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8786 added --disable-pic16-port
8787 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8788 * src/SDCCmain.c: linkOptions is changed to set *,
8789 added if/endif conditional macros to remove options help
8790 messages from optionsTable when a port is not configured, added
8791 support for the PIc16 port in the ports table, when executing
8792 the compiler with no port specified on command line, a default
8793 port is selected with the new macro DEFAULT_PORT which is
8794 defined in port.h, in setDefaultOptions() linkOptions is removed
8795 from initialization assignment, since now it is a set,
8796 parseCmdLine uses setParseWithComma for linkOptions, in
8797 linkEdit() linkOptions are accessed with new function indexSet()
8798 which returns the i'th item of a set variable. See SDCCset.c, in
8799 linkEdit() when calling buildCmdLine(), added linkOptions as
8800 last argument. Now users can pass arguments to gplink via the
8801 -Wl option, main() uses pic16glue() to glue up pic16 programs

8813 * src/pic16/glue.c: commented out some error producing lines
8814 * src/pic16/main.c: __config directives are commented out to stop
8815 gpasm complaining and test the linkage with gplink, _linkCmd and
8816 _asmCmd changed to be more gplink and gpasm friendly
8817 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8818 produced an error when parsed, peep rule 12 is added to utilize
8819 movff, but it is commented out since the pCode does not support
8820 yet a command with 2 address arguments
8822 2003-05-18 <johan AT balder>
8824 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8825 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8849 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8851 2003-05-11 Borut Razem <borut.razem AT siol.net>
8853 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8854 the path of bin directory, so that PATH is the only env. variable, which has to be set
8855 in case of standard installation.
8856 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9888 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9889 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9890 following files to include the previous two files: aslink.dsp,
9891 Makefile.aslink, Makefile.bcc, and Makefile.in.
9893 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9894 .adb instead of .cdb
9896 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9898 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9899 value from option --iram-size.
9901 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9903 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9906 2002-09-18 <wiml AT hhhh.org>
9908 * SDCClrange.h: exposed setFromRange() and setToRange()
9909 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9910 packRegsForAccUse() (bug 542397)
9911 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9912 multiple times and emitting the fetch operations more than once
9913 added aopGetUsesAcc() function to allow binary operators to
9914 fetch their operands in the correct order; made genMinus() emit
9915 compact code for X = LITERAL - Y
9917 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9918 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9919 sprintf() in line 1267.
9921 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9925 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9926 Changes to aslink (All the changes are marked with 'JCF'):
9928 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9931 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9932 area BSEG. Also moves, if possible, the DATA area down into the internal
9933 ram so more space is available.
9935 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9938 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9939 not bytes. Function summary() which creates a memory usage summary
9940 file with extension .mem. Reports of overlaping stack and small stack
9941 size. If the space for the stack is less than 16 bytes aslink trows a
9944 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9945 the 8051. Option 'y' for memory summary output file.
9947 Changes to sdcc (All the changes are marked with 'JCF'):
9949 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9951 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9952 overlaying area for it (uses RegBankUsed[4]).
9954 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9955 bank zero as used by default. By default aslink locates the stack
9956 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9957 the creation of the .mem file. Delegates the allocation of data area
9958 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9959 the begining of the stack area to aslink.
9961 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9962 glue() in SDCCglue.c creates an area for it.

9965 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9966 sdcc/src/pic/glue.c:
9967 introduced atexit() handler for teporay files removal in case of
9968 errors, assertions, ...
9970 2002-08-29 Borut Razem <borut.razem AT siol.net>
9971 * sdcc/support/cpp2/auto-host_vc_in.h:
9972 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9973 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9974 Maybe there is a similar problem with BORLANDC? It should be checked!
9976 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9977 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9978 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9979 was not executed, and the compiler (cl) launched a warning:
9980 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9982 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9983 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9985 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9986 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9988 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9989 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9990 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9991 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9992 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9993 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9994 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9995 - added Release configuration in VS projects
9996 - review of compiler an linker options
9997 - VC .exe files are generated in bin_vc directory, not to interfere
9998 with binaries generated from other projects (cygwin, mingw, bcc ...)
10000 * sdcc/src/yacc.dsp: added
10002 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10003 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10004 and insert the version number definitions from .version
10006 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10008 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10009 added - genarate auto-host.h using auto-host_vc_in.h as template
10012 removed from CVS, generated automatically
10014 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10015 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10017 2002-08-11 Borut Razem <borut.razem AT siol.net>
10018 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10020 2002-08-10 Borut Razem <borut.razem AT siol.net>
10021 * src/SDCCmain.c (main):
10022 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10023 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10024 The consequence was that some temporary files were not removed.
10027 unification of code in functions tempfilename() and tempfile():
10028 function tempnam() is defined in Visual Studio 6.0 and .NET
10030 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10032 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10033 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10034 - removed compiler command line option /WX: Treats all warnings as errors
10035 - update a list of source files, included into the project
10037 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10038 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10039 changed project type to Generic Project so that can be correcly converted to VS.NET project
10041 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10043 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10045 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10047 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10048 added return 0 statements after assert() to make compiler happy
10050 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10051 added newline in the def file to keep MSC compiler satisfied
10053 * sdcc/src/z80/gen.c:
10054 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10055 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10056 - solved MSC error in function aopDump()
10058 * sdcc_vc.h: define PREFIX as "\\sdcc"
10060 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10061 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10064 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10065 - Rewrote the register banking algorithm.
10066 - Added pCode live-range analysis to registers (for now, only non-used and
10067 singly-used registers optimized away)
10069 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10098 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10100 2002-03-28 Johan Knol <johan AT balder>
10102 * src/SDCCval.c: fixed bug #532436

10233 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10235 * sdcc/src/SDCCloop.c:
10236 Previous fix was not good. basic blocks that have "break" or "return" are
10237 not really partof a loop , but live ranges used in these blocks should
10238 be live thru the entire loop, so set partOfLoop but don't add them to
10241 2002-02-21 <johan AT FRIJA>
10243 * src/SDCCcse.c: fixed bug #514308
10245 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
