3 Enabled VPATH feature: changed nearly all Makefiles (149 files).
4 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
6 One basic decision: e.g. src/clean.mk includes further files. In order
7 to make this work there are two solutions:
8 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
9 run configure on them. This way they can use
10 'include $(srcdir)/port-clean.mk'
11 - always include clean.mk by the Makefile at the same level. To avoid
12 that `make clean` tries to include and build Makefile.dep the
13 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
14 implemented, because now even `make uninstall` doesn't create
15 Makefile.in. clean.mk could be eliminated by pasting it in
18 * debugger/mcs51/Makefile.in: build own objects from library sources
19 (SLIB, SDCC) in current directory
21 * configure, configure.in: renamed --disable-device-lib-build in
22 --disable-device-lib; added --enable-doc, the required tools are
23 searched by configure; added result message; the toolchain for the
24 belonging ports are now only built, if the port is enabled.
26 * support/regression/*: all output is written in directory gen, because
27 the fwk and ports directories don't livet in the build tree using vpath
29 * doc/sdccman.lyx: renamed --disable-device-lib-build to
30 --disable-device-lib, added --enable-doc, added section VPATH
32 * sim/ucsim/configure.in,
33 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
34 z80 are enabled by default
36 2006-04-24 Raphael Neider <rneider AT web.de>
38 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
39 config word, "pic14_"-prefixed some extern functions
40 (pic14_emitConfigWord): emit __config directive(s) if assignment to
41 config word has been found
42 * src/pic/device.h: added prototypes
43 * src/pic/pcode.c: added "pic14_"-prefix where needed
44 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic fixup
45 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config words,

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

315 submitted by the Debian SDCC maintainer Aurelien Jarno:
316 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
317 archive with gcc 4.1 on mips and wrote the patch"
319 2006-03-16 Raphael Neider <rneider AT web.de>
321 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
322 the left operand is shorter than the result (c* = lit-c* + int),
324 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
327 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
329 * src/.version: increased version number to 2.5.5
330 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
331 linking is done manually in pic16 port's _linkEdit,
332 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
333 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
334 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
335 allocate asmop as AOP_ACC,
336 (aopForRemat): added parameter 'bool result' in function declaration,

349 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
350 call to allocReg, not by manually allocating a new one,
351 (pic16_assignRegisters): now before going through the register
352 allocating functions mark all registers as free. This eliminates some
353 side effects resulting from peephole parser done earlier in the backbone
355 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
357 * src/SDCCicode.c (geniCodeLogic),

402 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
403 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
405 2006-03-06 Borut Razem <borut.razem AT siol.net>
407 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
408 made the linker quiet
410 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
412 * src/pic16/gen.c (genPcall): fixed bug #1443644
413 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
414 which dumps before the function entry point a data byte which represents
415 the number of the local variables used by the specified function, added
416 'xinst' for initial support for Extended Instruction Support,
417 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
418 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
419 port->fun_prefix anymore (may change later),
420 (genFunction, genEndFunction): do not store/restore local registers for
421 _main (this should take care the --main-return command line option in
423 (genOr): removed some legacy pic-port instructions,
424 * src/pic16/genarith.c (genAddLit): re-enabled old code because
425 performing operations with SFR's causes data to be written more than
426 once to each SFR. Perhaps SFRs should be handled in special cases...
427 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
429 * src/pic16/main.c (_process_pragma): stack bound checking did not take
430 into account for stack starting position,
431 (struct OPTIONS pic16_optionsTable): added command line argument
432 --extended or -y for Extended Instruction Support,
433 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
434 (deassignLRs): *** perhaps the most important change, old 'for' code
435 (commented out for reference), didn't account for some registers which
436 were left marked 'not free' after a pointer operation. The change
437 reduces register usage a lot in some cases
439 2006-03-04 Borut Razem <borut.razem AT siol.net>
441 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

447 2006-03-03 Borut Razem <borut.razem AT siol.net>
449 * support/regression/fwk/lib/testfwk.c,
450 support/regression/fwk/include/testfwk.h: introduced function

2710 * src/SDCCglobal.h (struct options),
2712 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2713 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2714 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2715 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2716 always available in leading double underscore form. The C99 support is
2717 mostly missing, but it's a start.
2718 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2719 reserved identifier "__data".
2721 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2797 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2799 * device/lib/printf_large.c: removed inline assembly for portability and
2800 readability. Use printf_fast if speed or size are more important.
2801 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2802 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2804 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2806 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2807 prevent compiler warning
2809 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2811 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2812 moved to level 0 and declared as static. Also they are explicit
2813 placed in access bank. This was necessery because some times they
2814 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2815 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2816 optimizations. Currently only compare to unsigned char is implemented,
2817 * src/pic16/gen.c: added fReturnIdx array,
2818 * (struct resolvedIfx) is moved to gen.h and made public,
2819 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2820 * (aopForSym): added an optimization to directly store in stack of
2821 the operand of a SEND iCode,
2822 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2823 but as registers instead (AOP_REG) using the fReturnIdx array,
2824 * (pic16_freeAsmop): remove the freed register from the
2825 _G.sregsAlloc field,
2826 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2827 a compare of 'WREG',
2828 * (pic16_popGetTempRegCond): changed function prototype, now
2829 function takes also a bitVector argument v which holds the current
2830 set of registers that are allocated for stack access by aopForSym,
2831 registers allocated in aopForSym for accessing stack symbols are not
2832 any more part of the functions usedRegs field,
2833 * (genCall): some times aopOp is called for a stack variable to be
2834 send, aopForSym might perform the push, if this is true make sure
2835 that genCall doesn't push the variable twice by testing _G.resDirect,
2836 * (genFunction): changed testing for unspecified interrupt number
2837 from 256 to INTNO_UNSPEC,
2838 * modified selection scheme of frame pointer generation. Previously
2839 if function did use local registers a frame pointer was generated,
2840 now a frame pointer is generated only if function has arguments
2841 (that need PLUSW2 register access), or has stack arguments, or the
2842 compiler is not instructed to omit the frame pointer,
2843 * (genEndFunction): before restoring local registers that were saved
2844 in the function preamble, also restore the registers that *might*
2845 have been allocated for stack access,
2846 * (genRet): removed some old comments,
2847 * (genCmp, the active (RN's) version): added a call to the
2848 pic16_genCmp_special function to perform the compare with a more
2849 robust and optimized way,
2850 * (genInline): a feature has been added in inline code generation,
2851 which allows a wildcard variable substitution when writing inline
2852 assembly. Code is incomplete and experimental therefore undocumented,
2853 * (genCast): changed order of aopOp for result and right to allow
2854 aopForSym to directly load the result if possible,
2855 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2856 perform an optimized compare on some selected special occasions,
2857 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2858 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2859 generate an IVT any more,
2860 * src/pic16/main.c (pic16_optionsTable): added command line option
2862 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2863 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2865 * src/pic16/NOTES: Raphael Neider added in list of active developers
2866 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2867 jumptable_end to prevent bug #,
2868 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2869 inCond and outCond fields,
2870 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2871 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2872 turn off register spilling,
2873 * (packRegsForOneUse): synced with other ports' versions although it
2874 is not used currently,
2875 * (pic16_packRegisters): added an optimization while reading
2876 structure bitfields, some registers may be saved (malloc code is
2877 decreased by 80 bytes)
2879 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2881 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2882 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2883 this can be optimized more?
2885 2005-03-10 Raphael Neider <rneider AT web.de>
2887 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2888 genNearPointerGet): (hopefully) fixed access to bitfields via
2889 pointers (p->bitN = x; and x = p->bitN; failed)
2891 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2935 to keep the correct label reference count when adding/removing references
2936 to labels. A peephole file using this is appended to patch #1144962.

3523 Adding support for replacing ljmps with sjmps in jumptables
3524 generated for switch statements. For now you need to set the
3525 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3526 Now 4 algorithms for mcs51 jumptable generation are used:
3527 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3528 addresses loaded pc-relative for up to 112 cases and stack-pushing
3529 target addresses loaded with offset from dptr for up to 256 cases.

3556 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3557 to call when a stack overflow occurs,
3558 * (malloc.h): added CVS Id tag,
3559 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3561 * added libc directory. The current version of LibC contains string
3562 functions, ctype functions and macros and some functions of the
3563 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3564 be extensively tested in the future. Standard disclaimer here.
3565 Library is not automatically build yet. But one can build it by
3566 invoking 'make' inside the libc directory.
3567 * added ADC library under libio. Preliminary version yet.

3576 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3577 * (pic16_storeForReturn): optimized return of 0,
3578 * (genCmp): experimental code for new genCmp which uses PIC18's
3579 special compare&skip instructions. Initial tests fail some times
3580 with variables grater than 1 byte in size, so new code is disabled,
3581 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3583 * (genCast): began a fix to optimize the casting of a bit to another
3584 bit, now assigning a bitfield to another bitfield will fail, sorry,
3585 * src/pic16/main.c: disabled the use of lr-support feature,
3586 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3589 bits with offset (case PO_GPR_BIT),
3590 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3592 * (isBankInstruction): modified to return 0 for no banking instruction,
3593 and 1 for banking instruction,
3594 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3595 caused stop processing pCodes after a inline assembly block,
3596 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3597 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3598 registers when it shouldn't,
3599 * src/pic16/ralloc.c (allocReg): add preliminary support for
3600 supporting a limited set of temporary registers,
3602 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3604 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3605 genDataPointerSet): ensure assignments always copy in MSB to LSB
3607 (loadRegFromAop): recognize CLRH optimization,
3608 (genFunction): optimize RECEIVE iCodes in reentrant functions
3610 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3612 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6539 * src/pic/glue (pic14emitRegularMap),
6540 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6542 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6544 * src/pic/pcode.c (PCodeID): commented out left over debug code
6546 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6548 * support/valdiag/tests/overflow.c: added shift tests
6556 * src/pic/pcodepeep.c,
6557 * src/pic/pcoderegs.c,
6559 * src/pic/ralloc.h: applied patch from Slade Rich;
6560 added support for multiple code pages and multiple RAM banks on the
6561 PIC 14 port. The ASM files now no longer simply assume all the
6562 code / RAM are in the same page / bank. This means the linker can
6563 safely allocate code/RAM of separate ASM files to different pages/banks.
6564 * doc/sdccman.lyx: added Slade's tips
6565 * src/mcs51/peeph.def: fixed bug #880768

6574 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6577 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6578 strtof is not part of C89 and isn't included with Mac OS X.
6580 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6582 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6607 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6609 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6610 loaded with the linker search paths (-L arguments) and the libraries
6611 to be linked with the current source (-l arguments). Changes
6612 currently will affect only the pic16 port.
6613 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6614 include path the port specific paths and port specific libraries,
6615 * gplink command now contains the $3 argument,
6616 * src/pic16/device.h,
6617 * src/pic16/device.c,: structure PIC_device is made public and
6618 renamed to PIC16_device, the same for variable Pics which is renamed
6619 to Pics16. Updated all references to them.
6620 * src/pic16/glue.c (pic16glue): corrected bug with code
6621 initialization which bypassed the variable initializations block.

6631 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6633 Documenting changes from previous commits.
6634 * configure.in (version 1.56),
6635 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6636 when generating output files to configure the pic16 library,
6637 but now I've commented it out, since gputils aren't installed in the
6638 SF compile farm, so library won't compile
6640 * device/lib/Makefile.in (version 1.56): initially I've added in
6641 target 'all' the prerequestive 'model-pic16' so it compiled the
6642 pic16 library, but now I've commented it out for the same reasons
6644 * added targets 'model-pic16' and 'objects-pic16' to compile the
6646 * added target 'port-specific-objects-pic16' to handle the
6647 generated libraries and copy them into the build/ directory
6648 * added target 'clean-intermediate-pic16' to clean intermediate
6649 files into pic16 directory
6650 * in target 'installdirs' added line to create directory pic16 in
6651 the installation path
6653 * device/include/Makefile.in (version 1.11): in target 'install'
6654 added lines to copy all header files to installation path,
6655 * in target 'installdirs' added line create directory for pic16
6656 headers in the installation path

6671 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6672 option so that it actually works. Made it specific to the z80, since
6673 the gbz80 doesn't have these kinds of I/O ports.
6675 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6677 * device/include/z180.h,

6699 Mainly changes to support compilation of the device libraries
6700 * src/pic16/device.c: stack is allocated via symbol and not
6701 via literal number. The symbol is placed in the corresponding
6702 position of the data ram
6703 * (pic16_dump_section): relocatable and absolute uninitialized
6704 data are now emitted in sorted order to reduce section naming,
6705 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6706 weren't marked as being in the access bank,
6708 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6710 Added portion of GNU PIC Library under the directory
6711 device/include/pic16 and device/lib/pic16. These files
6712 contain the declarations of SFRs for the PIC18Fxx2 devices.
6713 The directory is initialized via configure from toplevel.
6715 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6717 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6743 all over. Telling LaTeX to be less strict with word spacing
6744 to better keep the right margin. Changed some notes about
6745 maintainance of the ports in section 3.2.1 - is it OK like this?
6747 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6785 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6787 * src/pic16/peeph.def: all peepholes with movff are commented out,
6788 because there is a problem in the pcode peep optimizer,
6789 * src/pic16/ralloc.c: the register allocator can now reuse local

6851 override default uninitialized data segment definition for
6852 devices only with SHAREBANK memory (reported from Erik Epetrich)
6853 * (pic14emitOverlay): modified to emit a commented overlay segment
6854 directive when no overlay data exist
6855 * (picglue): modified to emit uninitialized data segment
6856 according to udata_section_name

6909 * support/valdiag/Makefile,
6910 * support/valdiag/valdiag.py,
6911 * support/valdiag/tests/*

6941 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6943 PIC16 port related changes:
6944 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6945 added variable stackPos,
6947 * gen.c: genCall, assignResultValue: added support for
6948 pushing/retrieving function parameters to/from stack,
6949 genFunction,genEndFunction: setup stack frame for the
6951 genAddrOf: will be changed according to bug 863624
6953 * added files genutils.c and genutils.h which contain gen*
6954 debugged and optimised functions extracted from gen.c
6956 * glue.c: added variable 'externs' which holds extern symbols,
6957 pic16emitRegularMap: is modified to properly handle relocatable
6958 symbols under the new scheme,
6959 pic16createInterruptVect: is modified
6960 pic16printPublics: is modified to emit 'global' assembler directives,
6961 added pic16_printExterns to print extern symbols,
6962 pic16glue: initializes stack/frame pointer in the beginning of
6963 the assembly output. Temporary hack, will be corrected later,
6964 because gplink yet does not support stack and SDCC does not
6965 yet support a type of crt0.o object to create the final binary.
6967 * Removed many lines that contain 8051 legacy code.
6968 * The code is finally placed under a 'code' directive.
6969 * Added port specific options.
6971 * _process_pragma: simplified since now we do not need *special*
6972 include file to define SFR registers. But a separate header
6973 will be needed. This will be developed later.
6974 * _pic16_parseOptions: added, parses port specific options:
6975 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6976 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6977 --preplace-udata-with=
6979 * _pic16_setDefaultOptions: modified to initialize section names,
6980 but hack is temporarly out of order since it needs improvement.
6981 * _pic16_genAssemblerPreamble: configuration words are emitted by
6982 their address instead of their name. This part is incomplete and
6983 supports only the 18Fxx2 devices. Other devices will emit an error
6984 during assembly since they do not contain the same set of config
6986 * _pic16_genIVT: is modified,
6988 * pcode.c: added definitions for some hardware registers that are needed
6990 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6991 All PCI entries are updated. Now LFSR is supported.
6992 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6993 * added pic16_newpCodeOpLit2 to support instructions with
6994 two literal arguments
6995 * pic16_pCode2str: corrected code that emits assembler instructions
6996 with two literal operands and those that have an access bit modifier
6997 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6998 this fixes a bug which caused some labels to be lost, when an
6999 assembler directive was added, i.e. banksel,
7000 * pic16_FixRegisterBanking: improved logic that causes the insertion
7002 * InlineFunction: functions that are called once, are not any more
7003 inlined. This can be a port option in the future,
7005 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7007 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7008 hold the corresponding uninitialized symbols,
7009 * pic16_allocProcessorRegister: registers have explicit marked the
7011 * pic16_allocInternalRegister: registers are explicit marked as
7013 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7014 processing list, so bit registers were lost,
7017 * ralloc.h: added field 'accessBank' and original symbol operand
7018 in register definition,
7019 * removed the field isMapped from register definition,
7021 ** Several functions have been removed from various sources:
7022 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7023 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7024 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7025 pic16_assignRelocatableRegisters
7027 ** others have been introduced:
7028 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7029 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7031 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7033 * support/scripts/inc2h.pl: changed definition of BIT_AT
7034 to emit 'sbit at' instead of 'bit at'. This was a request.
7036 PIC16 port related preliminary changes:
7037 * gen.c: prefixed function popRegFromString with
7038 pic16_ and all references to it corrected
7039 * pcode.c: all pic16_pc_* hardware registers prefixed
7040 with underscore (_),
7041 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7042 * ralloc.c: newReg(): when register is REG_SFR then
7043 set address to rIdx,
7044 pic16_allocProcessorRegister(): marks register wasUsed=0
7045 pic16_writeUsedRegs(): added a call to assign processor
7046 registers via pic16_assignFixedRegisters
7048 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7050 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7051 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7052 variables in unused register banks. Also the SSEG is placed
7053 wherever there is enough space for it, and IDATA can be anywhere
7054 in internal RAM. For now compile using -Wl-Y[stack_size].
7055 The mem file is different for this option as well, since it
7056 makes no sense of talking about DSEG lenght.
7058 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7060 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7305 * src/SDCCast.c (decorateType): disabled a transformation I added in
7306 revision 1.188 (access to fields of a structure at an absolute address);
7307 it breaks with bitfields, extern declarations, and gcse analysis.
7308 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7309 could be assigned through a pointer, so don't complain.

8033 reported in bug #800609
8035 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8037 * Top header beautifications in src/pic16 directory:
8038 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8039 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8040 pcoderegs.h, ralloc.c, ralloc.h
8041 * main.c: added top header and GPL license notice
8042 * pcode.c: fixed the if-conditional warning
8044 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8046 * device/lib/_mullong.c: replaced int by short for gcc
8048 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8050 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8051 and JUMPTABLE iCodes properly now (worked by accident before)
8052 * src/mcs51/gen.c (leftRightUseAcc),
8053 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8054 iCode properly now. Use getSize instead of nRegs since a & b
8055 aren't part of the nRegs tally.
8057 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8059 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8060 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8061 before instructions that use the _STATUS register
8063 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8065 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8066 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8067 fetching of the pointer
8068 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8069 copied from genNearPointerSet()
8070 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8071 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8072 If they pop r0/r1 they must be called in the opposite order than aopOp().
8073 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8074 (resp. --stack-auto), prepared for --xstack
8076 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8080 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8082 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8083 these ports have their own __sdcc_external_start()
8085 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8087 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8088 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8089 type for bits was changed. It resulted in bit variables becoming
8090 global, which is not permitted in PIC 14 assembly output.
8092 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8094 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8096 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8098 Z80 and MCS51 linkers complaint if a public symbol is defined
8099 in more than one library module:
8103 * as/mcs51/Makefile.in
8105 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8107 A few small changes that speed up the peephole optimizer.
8111 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8113 Try to make the peephole optimizer smarter by maintaining
8114 an association between the assembly source code and the
8115 iCodes that originated them. Put this information to use
8116 with a new peephole rule condition "notVolatile" so that
8117 the rules can be aggressive yet still safe.
8122 * src/mcs51/peeph.def
8124 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8128 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8129 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8130 if the left or right operand symbols have the accuse flag set.
8132 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8134 Changed the type of the result of the ! (NOT) operator to char;
8135 previously it returned the same type as the source. This allows
8136 us to eliminate all the genFloatNot functions (all of its target
8137 implementations were very buggy) since !float can use the same
8140 * src/SDCCicode.c (ast2iCode): ! returns char
8141 * src/mcs51/gen.c (genNot, genNotFloat),
8142 * src/ds390/gen.c (genNot, genNotFloat),
8143 * src/z80/gen.c (genNot, genNotFloat),
8144 * src/pic/gen.c (genNot, genNotFloat),
8145 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8147 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8149 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8150 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8151 during interrupts. Ensure WSAVE is located at a shared bank address.
8152 2. Fixed page selection in some places
8153 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8154 the registers name strings.
8155 4. Fixed "signed / unsigned compare" compiler warnings.
8156 5. The PIC port manages its own allocation of the general purpose
8157 registers, but makes no attempt to reuse them. As a result when
8158 compiling it soon runs out of general purpose registers. Some
8159 additional code was added to the files pcode.c and device.c to walk
8160 through the function call tree and rename the registers so that they
8170 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8171 genPlus() & genMinus() when the result is the same as left or right

8177 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8179 Made bitfield a distinct type from bit so that bitfields
8180 convert as per ANSI C and bits retain their traditional
8181 boolean style behaviour. Implemented bitfield support in
8189 * src/ds390/gen.c: bit v bitfield split
8190 * src/z80/gen.c: New support for bitfields
8191 * support/regression/tests/bitfields.c: reenabled z80,
8194 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8196 Rules 246.x, 247.x relate to bitfields, the others speed up
8197 access to xdata mapped I/O devices.
8199 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8201 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8203 Cleaned up genPackBits and genUnpackBits and added two helper
8204 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8205 for literal assignments in genPackBits (thanks to Frieder for
8211 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8213 Fixed bug #748310 (pointer to function type mishandled when the
8214 function name is omitted). Also fixed a SIGSEGV when a function
8215 attribute (reentrant, etc) is used on a non-function or on a
8216 function but misplaced before the parameter list.
8218 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8220 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8221 * support/Util/SDCCerr.h,
8222 * support/Util/SDCCerr.c: Added func attr misuse error msg
8224 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8226 Fixed bug #787649 by anonymous
8227 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8243 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8245 Made the constant following the "interrupt" keyword optional. If
8246 omitted, the function will not automatically be given an entry
8247 in the interrupt vector table (similar to #pragma NOIV, but
8248 less syntacticly kludgy). The interrupt number is also now
8249 range checked. Also fixed a bug in the high order bit example
8256 * support/Util/SDCCerr.c
8257 * support/Util/SDCCerr.h
8260 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8263 * src/SDCCicode.c (operandOperation): rewritten some ops
8264 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8265 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8267 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8268 be re-activated by defining REDUCE_LITERALS)
8269 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8270 unsigned, but are signed by default
8271 * src/SDCCval.c (constVal): rearranged
8272 * src/SDCCval.c (valMod): preliminary fix
8273 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8316 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8317 * src/SDCCval.c (valDiv, valMod): fixed signdness
8318 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8319 signedness of modulo, left and right shift

8725 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8726 the regression tests I'm not brave enough to enable 245.b, 245.c
8727 * doc/sdccman.lyx: added latex preamble for hyperref package.
8728 Using pdflatex this will give you a hyperlinked pdf file with
8729 bookmarks. (prepend '%' before /usepackage if this breaks something)

8767 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8769 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8770 it can be defined with CFLAGS when running configure
8771 * src/SDCCmain.c: fixed compiling + linking with object files
8773 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8776 added --disable-pic16-port
8777 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8778 * src/SDCCmain.c: linkOptions is changed to set *,
8779 added if/endif conditional macros to remove options help
8780 messages from optionsTable when a port is not configured, added
8781 support for the PIc16 port in the ports table, when executing
8782 the compiler with no port specified on command line, a default
8783 port is selected with the new macro DEFAULT_PORT which is
8784 defined in port.h, in setDefaultOptions() linkOptions is removed
8785 from initialization assignment, since now it is a set,
8786 parseCmdLine uses setParseWithComma for linkOptions, in
8787 linkEdit() linkOptions are accessed with new function indexSet()
8788 which returns the i'th item of a set variable. See SDCCset.c, in
8789 linkEdit() when calling buildCmdLine(), added linkOptions as
8790 last argument. Now users can pass arguments to gplink via the
8791 -Wl option, main() uses pic16glue() to glue up pic16 programs

8803 * src/pic16/glue.c: commented out some error producing lines
8804 * src/pic16/main.c: __config directives are commented out to stop
8805 gpasm complaining and test the linkage with gplink, _linkCmd and
8806 _asmCmd changed to be more gplink and gpasm friendly
8807 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8808 produced an error when parsed, peep rule 12 is added to utilize
8809 movff, but it is commented out since the pCode does not support
8810 yet a command with 2 address arguments
8812 2003-05-18 <johan AT balder>
8814 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8815 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8839 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8841 2003-05-11 Borut Razem <borut.razem AT siol.net>
8843 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8844 the path of bin directory, so that PATH is the only env. variable, which has to be set
8845 in case of standard installation.
8846 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9878 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9879 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9880 following files to include the previous two files: aslink.dsp,
9881 Makefile.aslink, Makefile.bcc, and Makefile.in.
9883 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9884 .adb instead of .cdb
9886 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9888 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9889 value from option --iram-size.
9891 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9893 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9896 2002-09-18 <wiml AT hhhh.org>
9898 * SDCClrange.h: exposed setFromRange() and setToRange()
9899 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9900 packRegsForAccUse() (bug 542397)
9901 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9902 multiple times and emitting the fetch operations more than once
9903 added aopGetUsesAcc() function to allow binary operators to
9904 fetch their operands in the correct order; made genMinus() emit
9905 compact code for X = LITERAL - Y
9907 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9908 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

9915 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9916 Changes to aslink (All the changes are marked with 'JCF'):
9918 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9921 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9922 area BSEG. Also moves, if possible, the DATA area down into the internal
9923 ram so more space is available.
9925 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9928 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9929 not bytes. Function summary() which creates a memory usage summary
9930 file with extension .mem. Reports of overlaping stack and small stack
9931 size. If the space for the stack is less than 16 bytes aslink trows a
9934 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9935 the 8051. Option 'y' for memory summary output file.
9937 Changes to sdcc (All the changes are marked with 'JCF'):
9939 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9941 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9942 overlaying area for it (uses RegBankUsed[4]).
9944 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9945 bank zero as used by default. By default aslink locates the stack
9946 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9947 the creation of the .mem file. Delegates the allocation of data area
9948 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9949 the begining of the stack area to aslink.
9951 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9952 glue() in SDCCglue.c creates an area for it.

9955 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9956 sdcc/src/pic/glue.c:
9957 introduced atexit() handler for teporay files removal in case of
9958 errors, assertions, ...
9960 2002-08-29 Borut Razem <borut.razem AT siol.net>
9961 * sdcc/support/cpp2/auto-host_vc_in.h:
9962 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9963 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9964 Maybe there is a similar problem with BORLANDC? It should be checked!
9966 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9967 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9968 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9969 was not executed, and the compiler (cl) launched a warning:
9970 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9972 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9973 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9975 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9976 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9978 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9979 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9980 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9981 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9982 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9983 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9984 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9985 - added Release configuration in VS projects
9986 - review of compiler an linker options
9987 - VC .exe files are generated in bin_vc directory, not to interfere
9988 with binaries generated from other projects (cygwin, mingw, bcc ...)
9990 * sdcc/src/yacc.dsp: added
9992 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9993 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9994 and insert the version number definitions from .version
9996 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9998 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9999 added - genarate auto-host.h using auto-host_vc_in.h as template
10002 removed from CVS, generated automatically
10004 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10005 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10007 2002-08-11 Borut Razem <borut.razem AT siol.net>
10008 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10010 2002-08-10 Borut Razem <borut.razem AT siol.net>
10011 * src/SDCCmain.c (main):
10012 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10013 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10014 The consequence was that some temporary files were not removed.
10017 unification of code in functions tempfilename() and tempfile():
10018 function tempnam() is defined in Visual Studio 6.0 and .NET
10020 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10022 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10023 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10024 - removed compiler command line option /WX: Treats all warnings as errors
10025 - update a list of source files, included into the project
10027 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10028 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10029 changed project type to Generic Project so that can be correcly converted to VS.NET project
10031 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10033 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10035 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10037 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10038 added return 0 statements after assert() to make compiler happy
10040 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10041 added newline in the def file to keep MSC compiler satisfied
10043 * sdcc/src/z80/gen.c:
10044 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10045 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10046 - solved MSC error in function aopDump()
10048 * sdcc_vc.h: define PREFIX as "\\sdcc"
10050 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10051 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10054 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10055 - Rewrote the register banking algorithm.
10056 - Added pCode live-range analysis to registers (for now, only non-used and
10057 singly-used registers optimized away)

10088 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10090 2002-03-28 Johan Knol <johan AT balder>
10092 * src/SDCCval.c: fixed bug #532436

10223 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10225 * sdcc/src/SDCCloop.c:
10226 Previous fix was not good. basic blocks that have "break" or "return" are
10227 not really partof a loop , but live ranges used in these blocks should
10228 be live thru the entire loop, so set partOfLoop but don't add them to
10231 2002-02-21 <johan AT FRIJA>
10233 * src/SDCCcse.c: fixed bug #514308
10235 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
