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

311 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
312 implemented patch 1120823 Thanks to Willy De la Court (normal
313 interrupts need an interrupt number now if they are made critical),
314 and enabled nesting of critical functions though not for gbz80
315 (genCritical, genEndCritical): added functions
316 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
317 * src/z80/mappings.i: added "ei" to all mappings

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

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

409 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
410 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
412 2006-03-06 Borut Razem <borut.razem AT siol.net>
414 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
415 made the linker quiet
417 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
419 * src/pic16/gen.c (genPcall): fixed bug #1443644
420 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
421 which dumps before the function entry point a data byte which represents
422 the number of the local variables used by the specified function, added
423 'xinst' for initial support for Extended Instruction Support,
424 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
425 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
426 port->fun_prefix anymore (may change later),
427 (genFunction, genEndFunction): do not store/restore local registers for
428 _main (this should take care the --main-return command line option in
430 (genOr): removed some legacy pic-port instructions,
431 * src/pic16/genarith.c (genAddLit): re-enabled old code because
432 performing operations with SFR's causes data to be written more than
433 once to each SFR. Perhaps SFRs should be handled in special cases...
434 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
436 * src/pic16/main.c (_process_pragma): stack bound checking did not take
437 into account for stack starting position,
438 (struct OPTIONS pic16_optionsTable): added command line argument
439 --extended or -y for Extended Instruction Support,
440 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
441 (deassignLRs): *** perhaps the most important change, old 'for' code
442 (commented out for reference), didn't account for some registers which
443 were left marked 'not free' after a pointer operation. The change
444 reduces register usage a lot in some cases
446 2006-03-04 Borut Razem <borut.razem AT siol.net>
448 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

2720 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2721 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2722 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2723 always available in leading double underscore form. The C99 support is

2804 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2806 * device/lib/printf_large.c: removed inline assembly for portability and
2807 readability. Use printf_fast if speed or size are more important.
2808 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2809 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2811 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2813 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2814 prevent compiler warning
2816 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2818 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2819 moved to level 0 and declared as static. Also they are explicit
2820 placed in access bank. This was necessery because some times they
2821 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2822 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2823 optimizations. Currently only compare to unsigned char is implemented,
2824 * src/pic16/gen.c: added fReturnIdx array,
2825 * (struct resolvedIfx) is moved to gen.h and made public,
2826 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2827 * (aopForSym): added an optimization to directly store in stack of
2828 the operand of a SEND iCode,
2829 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2830 but as registers instead (AOP_REG) using the fReturnIdx array,
2831 * (pic16_freeAsmop): remove the freed register from the
2832 _G.sregsAlloc field,
2833 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2834 a compare of 'WREG',
2835 * (pic16_popGetTempRegCond): changed function prototype, now
2836 function takes also a bitVector argument v which holds the current
2837 set of registers that are allocated for stack access by aopForSym,
2838 registers allocated in aopForSym for accessing stack symbols are not
2839 any more part of the functions usedRegs field,
2840 * (genCall): some times aopOp is called for a stack variable to be
2841 send, aopForSym might perform the push, if this is true make sure
2842 that genCall doesn't push the variable twice by testing _G.resDirect,
2843 * (genFunction): changed testing for unspecified interrupt number
2844 from 256 to INTNO_UNSPEC,
2845 * modified selection scheme of frame pointer generation. Previously
2846 if function did use local registers a frame pointer was generated,
2847 now a frame pointer is generated only if function has arguments
2848 (that need PLUSW2 register access), or has stack arguments, or the
2849 compiler is not instructed to omit the frame pointer,
2850 * (genEndFunction): before restoring local registers that were saved
2851 in the function preamble, also restore the registers that *might*
2852 have been allocated for stack access,
2853 * (genRet): removed some old comments,
2854 * (genCmp, the active (RN's) version): added a call to the
2855 pic16_genCmp_special function to perform the compare with a more
2856 robust and optimized way,
2857 * (genInline): a feature has been added in inline code generation,
2858 which allows a wildcard variable substitution when writing inline
2859 assembly. Code is incomplete and experimental therefore undocumented,
2860 * (genCast): changed order of aopOp for result and right to allow
2861 aopForSym to directly load the result if possible,
2862 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2863 perform an optimized compare on some selected special occasions,
2864 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2865 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2866 generate an IVT any more,
2867 * src/pic16/main.c (pic16_optionsTable): added command line option
2869 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2870 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2872 * src/pic16/NOTES: Raphael Neider added in list of active developers
2873 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2874 jumptable_end to prevent bug #,
2875 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2876 inCond and outCond fields,
2877 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2878 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2879 turn off register spilling,
2880 * (packRegsForOneUse): synced with other ports' versions although it
2881 is not used currently,
2882 * (pic16_packRegisters): added an optimization while reading
2883 structure bitfields, some registers may be saved (malloc code is
2884 decreased by 80 bytes)
2886 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2888 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2889 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2890 this can be optimized more?
2892 2005-03-10 Raphael Neider <rneider AT web.de>
2894 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2895 genNearPointerGet): (hopefully) fixed access to bitfields via
2896 pointers (p->bitN = x; and x = p->bitN; failed)
2898 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3530 Adding support for replacing ljmps with sjmps in jumptables
3531 generated for switch statements. For now you need to set the
3532 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3533 Now 4 algorithms for mcs51 jumptable generation are used:
3534 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3535 addresses loaded pc-relative for up to 112 cases and stack-pushing
3536 target addresses loaded with offset from dptr for up to 256 cases.
3538 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3539 * src/mcs51/main.c: adapted constants for switch table generation

3563 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3564 to call when a stack overflow occurs,
3565 * (malloc.h): added CVS Id tag,
3566 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3568 * added libc directory. The current version of LibC contains string
3569 functions, ctype functions and macros and some functions of the
3570 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3571 be extensively tested in the future. Standard disclaimer here.
3572 Library is not automatically build yet. But one can build it by
3573 invoking 'make' inside the libc directory.
3574 * added ADC library under libio. Preliminary version yet.
3576 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3583 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3584 * (pic16_storeForReturn): optimized return of 0,
3585 * (genCmp): experimental code for new genCmp which uses PIC18's
3586 special compare&skip instructions. Initial tests fail some times
3587 with variables grater than 1 byte in size, so new code is disabled,
3588 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3590 * (genCast): began a fix to optimize the casting of a bit to another
3591 bit, now assigning a bitfield to another bitfield will fail, sorry,
3592 * src/pic16/main.c: disabled the use of lr-support feature,
3593 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3596 bits with offset (case PO_GPR_BIT),
3597 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3599 * (isBankInstruction): modified to return 0 for no banking instruction,
3600 and 1 for banking instruction,
3601 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3602 caused stop processing pCodes after a inline assembly block,
3603 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3604 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3605 registers when it shouldn't,
3606 * src/pic16/ralloc.c (allocReg): add preliminary support for
3607 supporting a limited set of temporary registers,
3609 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3611 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3612 genDataPointerSet): ensure assignments always copy in MSB to LSB
3614 (loadRegFromAop): recognize CLRH optimization,
3615 (genFunction): optimize RECEIVE iCodes in reentrant functions
3617 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3619 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6546 * src/pic/glue (pic14emitRegularMap),
6547 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6549 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6551 * src/pic/pcode.c (PCodeID): commented out left over debug code
6553 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6555 * support/valdiag/tests/overflow.c: added shift tests
6563 * src/pic/pcodepeep.c,
6564 * src/pic/pcoderegs.c,
6566 * src/pic/ralloc.h: applied patch from Slade Rich;
6567 added support for multiple code pages and multiple RAM banks on the
6568 PIC 14 port. The ASM files now no longer simply assume all the
6569 code / RAM are in the same page / bank. This means the linker can
6570 safely allocate code/RAM of separate ASM files to different pages/banks.
6571 * doc/sdccman.lyx: added Slade's tips
6572 * src/mcs51/peeph.def: fixed bug #880768

6581 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6584 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6585 strtof is not part of C89 and isn't included with Mac OS X.
6587 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6589 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6614 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6616 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6617 loaded with the linker search paths (-L arguments) and the libraries
6618 to be linked with the current source (-l arguments). Changes
6619 currently will affect only the pic16 port.
6620 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6621 include path the port specific paths and port specific libraries,
6622 * gplink command now contains the $3 argument,
6623 * src/pic16/device.h,
6624 * src/pic16/device.c,: structure PIC_device is made public and
6625 renamed to PIC16_device, the same for variable Pics which is renamed
6626 to Pics16. Updated all references to them.
6627 * src/pic16/glue.c (pic16glue): corrected bug with code
6628 initialization which bypassed the variable initializations block.
6630 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6631 COMPILE_FLAGS and added the --nostdinc option
6633 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6640 Documenting changes from previous commits.
6641 * configure.in (version 1.56),
6642 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6643 when generating output files to configure the pic16 library,
6644 but now I've commented it out, since gputils aren't installed in the
6645 SF compile farm, so library won't compile
6647 * device/lib/Makefile.in (version 1.56): initially I've added in
6648 target 'all' the prerequestive 'model-pic16' so it compiled the
6649 pic16 library, but now I've commented it out for the same reasons
6651 * added targets 'model-pic16' and 'objects-pic16' to compile the
6653 * added target 'port-specific-objects-pic16' to handle the
6654 generated libraries and copy them into the build/ directory
6655 * added target 'clean-intermediate-pic16' to clean intermediate
6656 files into pic16 directory
6657 * in target 'installdirs' added line to create directory pic16 in
6658 the installation path
6660 * device/include/Makefile.in (version 1.11): in target 'install'
6661 added lines to copy all header files to installation path,
6662 * in target 'installdirs' added line create directory for pic16
6663 headers in the installation path

6678 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6679 option so that it actually works. Made it specific to the z80, since
6680 the gbz80 doesn't have these kinds of I/O ports.
6682 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6684 * device/include/z180.h,

6706 Mainly changes to support compilation of the device libraries
6707 * src/pic16/device.c: stack is allocated via symbol and not
6708 via literal number. The symbol is placed in the corresponding
6709 position of the data ram
6710 * (pic16_dump_section): relocatable and absolute uninitialized
6711 data are now emitted in sorted order to reduce section naming,
6712 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6713 weren't marked as being in the access bank,
6715 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6717 Added portion of GNU PIC Library under the directory
6718 device/include/pic16 and device/lib/pic16. These files
6719 contain the declarations of SFRs for the PIC18Fxx2 devices.
6720 The directory is initialized via configure from toplevel.
6722 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6724 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6750 all over. Telling LaTeX to be less strict with word spacing
6751 to better keep the right margin. Changed some notes about
6752 maintainance of the ports in section 3.2.1 - is it OK like this?
6754 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6792 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6794 * src/pic16/peeph.def: all peepholes with movff are commented out,
6795 because there is a problem in the pcode peep optimizer,
6796 * src/pic16/ralloc.c: the register allocator can now reuse local

6948 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6950 PIC16 port related changes:
6951 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6952 added variable stackPos,
6954 * gen.c: genCall, assignResultValue: added support for
6955 pushing/retrieving function parameters to/from stack,
6956 genFunction,genEndFunction: setup stack frame for the
6958 genAddrOf: will be changed according to bug 863624
6960 * added files genutils.c and genutils.h which contain gen*
6961 debugged and optimised functions extracted from gen.c
6963 * glue.c: added variable 'externs' which holds extern symbols,
6964 pic16emitRegularMap: is modified to properly handle relocatable
6965 symbols under the new scheme,
6966 pic16createInterruptVect: is modified
6967 pic16printPublics: is modified to emit 'global' assembler directives,
6968 added pic16_printExterns to print extern symbols,
6969 pic16glue: initializes stack/frame pointer in the beginning of
6970 the assembly output. Temporary hack, will be corrected later,
6971 because gplink yet does not support stack and SDCC does not
6972 yet support a type of crt0.o object to create the final binary.
6974 * Removed many lines that contain 8051 legacy code.
6975 * The code is finally placed under a 'code' directive.
6976 * Added port specific options.
6978 * _process_pragma: simplified since now we do not need *special*
6979 include file to define SFR registers. But a separate header
6980 will be needed. This will be developed later.
6981 * _pic16_parseOptions: added, parses port specific options:
6982 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6983 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6984 --preplace-udata-with=
6986 * _pic16_setDefaultOptions: modified to initialize section names,
6987 but hack is temporarly out of order since it needs improvement.
6988 * _pic16_genAssemblerPreamble: configuration words are emitted by
6989 their address instead of their name. This part is incomplete and
6990 supports only the 18Fxx2 devices. Other devices will emit an error
6991 during assembly since they do not contain the same set of config
6993 * _pic16_genIVT: is modified,
6995 * pcode.c: added definitions for some hardware registers that are needed
6997 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6998 All PCI entries are updated. Now LFSR is supported.
6999 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7000 * added pic16_newpCodeOpLit2 to support instructions with
7001 two literal arguments
7002 * pic16_pCode2str: corrected code that emits assembler instructions
7003 with two literal operands and those that have an access bit modifier
7004 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7005 this fixes a bug which caused some labels to be lost, when an
7006 assembler directive was added, i.e. banksel,
7007 * pic16_FixRegisterBanking: improved logic that causes the insertion
7009 * InlineFunction: functions that are called once, are not any more
7010 inlined. This can be a port option in the future,
7012 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7014 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7015 hold the corresponding uninitialized symbols,
7016 * pic16_allocProcessorRegister: registers have explicit marked the
7018 * pic16_allocInternalRegister: registers are explicit marked as
7020 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7021 processing list, so bit registers were lost,
7024 * ralloc.h: added field 'accessBank' and original symbol operand
7025 in register definition,
7026 * removed the field isMapped from register definition,
7028 ** Several functions have been removed from various sources:
7029 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7030 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7031 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7032 pic16_assignRelocatableRegisters
7034 ** others have been introduced:
7035 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7036 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7038 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7040 * support/scripts/inc2h.pl: changed definition of BIT_AT
7041 to emit 'sbit at' instead of 'bit at'. This was a request.
7043 PIC16 port related preliminary changes:
7044 * gen.c: prefixed function popRegFromString with
7045 pic16_ and all references to it corrected
7046 * pcode.c: all pic16_pc_* hardware registers prefixed
7047 with underscore (_),
7048 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7049 * ralloc.c: newReg(): when register is REG_SFR then
7050 set address to rIdx,
7051 pic16_allocProcessorRegister(): marks register wasUsed=0
7052 pic16_writeUsedRegs(): added a call to assign processor
7053 registers via pic16_assignFixedRegisters
7055 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7057 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7058 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7059 variables in unused register banks. Also the SSEG is placed
7060 wherever there is enough space for it, and IDATA can be anywhere
7061 in internal RAM. For now compile using -Wl-Y[stack_size].
7062 The mem file is different for this option as well, since it
7063 makes no sense of talking about DSEG lenght.
7065 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7067 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7312 * src/SDCCast.c (decorateType): disabled a transformation I added in
7313 revision 1.188 (access to fields of a structure at an absolute address);
7314 it breaks with bitfields, extern declarations, and gcse analysis.
7315 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7316 could be assigned through a pointer, so don't complain.

8040 reported in bug #800609
8042 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8044 * Top header beautifications in src/pic16 directory:
8045 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8046 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8047 pcoderegs.h, ralloc.c, ralloc.h
8048 * main.c: added top header and GPL license notice
8049 * pcode.c: fixed the if-conditional warning
8051 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8053 * device/lib/_mullong.c: replaced int by short for gcc
8055 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8057 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8058 and JUMPTABLE iCodes properly now (worked by accident before)
8059 * src/mcs51/gen.c (leftRightUseAcc),
8060 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8061 iCode properly now. Use getSize instead of nRegs since a & b
8062 aren't part of the nRegs tally.
8064 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8066 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8067 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8068 before instructions that use the _STATUS register
8070 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8072 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8073 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8074 fetching of the pointer
8075 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8076 copied from genNearPointerSet()
8077 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8078 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8079 If they pop r0/r1 they must be called in the opposite order than aopOp().
8080 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8081 (resp. --stack-auto), prepared for --xstack
8083 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8090 these ports have their own __sdcc_external_start()
8092 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8094 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8095 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8096 type for bits was changed. It resulted in bit variables becoming
8097 global, which is not permitted in PIC 14 assembly output.
8099 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8101 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8103 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8105 Z80 and MCS51 linkers complaint if a public symbol is defined
8106 in more than one library module:
8110 * as/mcs51/Makefile.in
8112 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8114 A few small changes that speed up the peephole optimizer.
8118 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8120 Try to make the peephole optimizer smarter by maintaining
8121 an association between the assembly source code and the
8122 iCodes that originated them. Put this information to use
8123 with a new peephole rule condition "notVolatile" so that
8124 the rules can be aggressive yet still safe.
8129 * src/mcs51/peeph.def
8131 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8135 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8136 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8137 if the left or right operand symbols have the accuse flag set.
8139 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8141 Changed the type of the result of the ! (NOT) operator to char;
8142 previously it returned the same type as the source. This allows
8143 us to eliminate all the genFloatNot functions (all of its target
8144 implementations were very buggy) since !float can use the same
8147 * src/SDCCicode.c (ast2iCode): ! returns char
8148 * src/mcs51/gen.c (genNot, genNotFloat),
8149 * src/ds390/gen.c (genNot, genNotFloat),
8150 * src/z80/gen.c (genNot, genNotFloat),
8151 * src/pic/gen.c (genNot, genNotFloat),
8152 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8154 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8156 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8157 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8158 during interrupts. Ensure WSAVE is located at a shared bank address.
8159 2. Fixed page selection in some places
8160 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8161 the registers name strings.
8162 4. Fixed "signed / unsigned compare" compiler warnings.
8163 5. The PIC port manages its own allocation of the general purpose
8164 registers, but makes no attempt to reuse them. As a result when
8165 compiling it soon runs out of general purpose registers. Some
8166 additional code was added to the files pcode.c and device.c to walk
8167 through the function call tree and rename the registers so that they
8177 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8178 genPlus() & genMinus() when the result is the same as left or right

8184 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8186 Made bitfield a distinct type from bit so that bitfields
8187 convert as per ANSI C and bits retain their traditional
8188 boolean style behaviour. Implemented bitfield support in
8196 * src/ds390/gen.c: bit v bitfield split
8197 * src/z80/gen.c: New support for bitfields
8198 * support/regression/tests/bitfields.c: reenabled z80,
8201 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8203 Rules 246.x, 247.x relate to bitfields, the others speed up
8204 access to xdata mapped I/O devices.
8206 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8208 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8210 Cleaned up genPackBits and genUnpackBits and added two helper
8211 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8212 for literal assignments in genPackBits (thanks to Frieder for
8218 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8220 Fixed bug #748310 (pointer to function type mishandled when the
8221 function name is omitted). Also fixed a SIGSEGV when a function
8222 attribute (reentrant, etc) is used on a non-function or on a
8223 function but misplaced before the parameter list.
8225 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8227 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8228 * support/Util/SDCCerr.h,
8229 * support/Util/SDCCerr.c: Added func attr misuse error msg
8231 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8233 Fixed bug #787649 by anonymous
8234 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8250 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8252 Made the constant following the "interrupt" keyword optional. If
8253 omitted, the function will not automatically be given an entry
8254 in the interrupt vector table (similar to #pragma NOIV, but
8255 less syntacticly kludgy). The interrupt number is also now
8256 range checked. Also fixed a bug in the high order bit example
8263 * support/Util/SDCCerr.c
8264 * support/Util/SDCCerr.h
8267 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8269 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8270 * src/SDCCicode.c (operandOperation): rewritten some ops
8271 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8272 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8274 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8275 be re-activated by defining REDUCE_LITERALS)
8276 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8277 unsigned, but are signed by default
8278 * src/SDCCval.c (constVal): rearranged
8279 * src/SDCCval.c (valMod): preliminary fix
8280 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8323 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8324 * src/SDCCval.c (valDiv, valMod): fixed signdness
8325 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8326 signedness of modulo, left and right shift

8732 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8733 the regression tests I'm not brave enough to enable 245.b, 245.c
8734 * doc/sdccman.lyx: added latex preamble for hyperref package.
8735 Using pdflatex this will give you a hyperlinked pdf file with
8736 bookmarks. (prepend '%' before /usepackage if this breaks something)

8774 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8776 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8777 it can be defined with CFLAGS when running configure
8778 * src/SDCCmain.c: fixed compiling + linking with object files
8780 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8783 added --disable-pic16-port
8784 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8785 * src/SDCCmain.c: linkOptions is changed to set *,
8786 added if/endif conditional macros to remove options help
8787 messages from optionsTable when a port is not configured, added
8788 support for the PIc16 port in the ports table, when executing
8789 the compiler with no port specified on command line, a default
8790 port is selected with the new macro DEFAULT_PORT which is
8791 defined in port.h, in setDefaultOptions() linkOptions is removed
8792 from initialization assignment, since now it is a set,
8793 parseCmdLine uses setParseWithComma for linkOptions, in
8794 linkEdit() linkOptions are accessed with new function indexSet()
8795 which returns the i'th item of a set variable. See SDCCset.c, in
8796 linkEdit() when calling buildCmdLine(), added linkOptions as
8797 last argument. Now users can pass arguments to gplink via the
8798 -Wl option, main() uses pic16glue() to glue up pic16 programs
8799 * src/SDCCpeeph.c: various changes to support pic16

8810 * src/pic16/glue.c: commented out some error producing lines
8811 * src/pic16/main.c: __config directives are commented out to stop
8812 gpasm complaining and test the linkage with gplink, _linkCmd and
8813 _asmCmd changed to be more gplink and gpasm friendly
8814 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8815 produced an error when parsed, peep rule 12 is added to utilize
8816 movff, but it is commented out since the pCode does not support
8817 yet a command with 2 address arguments
8819 2003-05-18 <johan AT balder>
8821 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8822 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8846 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8848 2003-05-11 Borut Razem <borut.razem AT siol.net>
8850 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8851 the path of bin directory, so that PATH is the only env. variable, which has to be set
8852 in case of standard installation.
8853 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9885 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9886 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9887 following files to include the previous two files: aslink.dsp,
9888 Makefile.aslink, Makefile.bcc, and Makefile.in.
9890 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9891 .adb instead of .cdb
9893 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9895 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9896 value from option --iram-size.
9898 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9900 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9903 2002-09-18 <wiml AT hhhh.org>
9905 * SDCClrange.h: exposed setFromRange() and setToRange()
9906 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9907 packRegsForAccUse() (bug 542397)
9908 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9909 multiple times and emitting the fetch operations more than once
9910 added aopGetUsesAcc() function to allow binary operators to
9911 fetch their operands in the correct order; made genMinus() emit
9912 compact code for X = LITERAL - Y
9914 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9915 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9916 sprintf() in line 1267.
9918 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9919 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9922 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9923 Changes to aslink (All the changes are marked with 'JCF'):
9925 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9928 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9929 area BSEG. Also moves, if possible, the DATA area down into the internal
9930 ram so more space is available.
9932 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9935 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9936 not bytes. Function summary() which creates a memory usage summary
9937 file with extension .mem. Reports of overlaping stack and small stack
9938 size. If the space for the stack is less than 16 bytes aslink trows a
9941 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9942 the 8051. Option 'y' for memory summary output file.
9944 Changes to sdcc (All the changes are marked with 'JCF'):
9946 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9948 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9949 overlaying area for it (uses RegBankUsed[4]).
9951 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9952 bank zero as used by default. By default aslink locates the stack
9953 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9954 the creation of the .mem file. Delegates the allocation of data area
9955 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9956 the begining of the stack area to aslink.
9958 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9959 glue() in SDCCglue.c creates an area for it.

9962 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9963 sdcc/src/pic/glue.c:
9964 introduced atexit() handler for teporay files removal in case of
9965 errors, assertions, ...
9967 2002-08-29 Borut Razem <borut.razem AT siol.net>
9968 * sdcc/support/cpp2/auto-host_vc_in.h:
9969 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9970 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9971 Maybe there is a similar problem with BORLANDC? It should be checked!
9973 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9974 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9975 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9976 was not executed, and the compiler (cl) launched a warning:
9977 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9979 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9980 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9982 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9983 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9985 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9986 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9987 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9988 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9989 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9990 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9991 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9992 - added Release configuration in VS projects
9993 - review of compiler an linker options
9994 - VC .exe files are generated in bin_vc directory, not to interfere
9995 with binaries generated from other projects (cygwin, mingw, bcc ...)
9997 * sdcc/src/yacc.dsp: added
9999 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10000 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10001 and insert the version number definitions from .version
10003 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10005 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10006 added - genarate auto-host.h using auto-host_vc_in.h as template
10009 removed from CVS, generated automatically
10011 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10012 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10014 2002-08-11 Borut Razem <borut.razem AT siol.net>
10015 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10017 2002-08-10 Borut Razem <borut.razem AT siol.net>
10018 * src/SDCCmain.c (main):
10019 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10020 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10021 The consequence was that some temporary files were not removed.
10024 unification of code in functions tempfilename() and tempfile():
10025 function tempnam() is defined in Visual Studio 6.0 and .NET
10027 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10029 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10030 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10031 - removed compiler command line option /WX: Treats all warnings as errors
10032 - update a list of source files, included into the project
10034 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10035 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10036 changed project type to Generic Project so that can be correcly converted to VS.NET project
10038 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10040 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10042 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10044 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10045 added return 0 statements after assert() to make compiler happy
10047 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10048 added newline in the def file to keep MSC compiler satisfied
10050 * sdcc/src/z80/gen.c:
10051 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10052 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10053 - solved MSC error in function aopDump()
10055 * sdcc_vc.h: define PREFIX as "\\sdcc"
10057 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10058 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10061 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10062 - Rewrote the register banking algorithm.
10063 - Added pCode live-range analysis to registers (for now, only non-used and
10064 singly-used registers optimized away)
10066 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10095 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10097 2002-03-28 Johan Knol <johan AT balder>
10099 * src/SDCCval.c: fixed bug #532436

10112 Compiler generated registers for interrupt context saving
10113 were not getting allocated.
10115 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

10230 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10232 * sdcc/src/SDCCloop.c:
10233 Previous fix was not good. basic blocks that have "break" or "return" are
10234 not really partof a loop , but live ranges used in these blocks should
10235 be live thru the entire loop, so set partOfLoop but don't add them to
10238 2002-02-21 <johan AT FRIJA>
10240 * src/SDCCcse.c: fixed bug #514308
10242 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
