877 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
879 Enabled VPATH feature: changed nearly all Makefiles (149 files).
880 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
882 One basic decision: e.g. src/clean.mk includes further files. In order
883 to make this work there are two solutions:
884 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
885 run configure on them. This way they can use
886 'include $(srcdir)/port-clean.mk'
887 - always include clean.mk by the Makefile at the same level. To avoid
888 that `make clean` tries to include and build Makefile.dep the
889 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
890 implemented, because now even `make uninstall` doesn't create
891 Makefile.in. clean.mk could be eliminated by pasting it in
894 * debugger/mcs51/Makefile.in: build own objects from library sources
895 (SLIB, SDCC) in current directory
897 * configure, configure.in: renamed --disable-device-lib-build in
898 --disable-device-lib; added --enable-doc, the required tools are
899 searched by configure; added result message; the toolchain for the
900 belonging ports are now only built, if the port is enabled.
902 * support/regression/*: all output is written in directory gen, because
903 the fwk and ports directories don't livet in the build tree using vpath
905 * doc/sdccman.lyx: renamed --disable-device-lib-build to
906 --disable-device-lib, added --enable-doc, added section VPATH
908 * sim/ucsim/configure.in,
909 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
910 z80 are enabled by default
912 2006-04-24 Raphael Neider <rneider AT web.de>
914 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
915 to config word, "pic14_"-prefixed some extern functions
916 (pic14_emitConfigWord): emit __config directive(s) if assignment to
917 config word has been found
918 * src/pic/device.h: added prototypes
919 * src/pic/pcode.c: added "pic14_"-prefix where needed
920 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
922 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
924 (pic14emitRegularMap): ignore config words,
925 (pic14createInterruptVect): moved generating __config directives away
926 (picglue): have __config directives emitted
928 2006-04-24 Borut Razem <borut.razem AT siol.net>
930 * doc/Makefile: sync with nightly build makefile
932 2006-04-24 Raphael Neider <rneider AT web.de>
934 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
935 registers that have not been assigned proper liveranges,
936 fixes #1469504 and #1474602,
937 (pCodeRegOptimizeRegUsage): fixed typo in comment

1184 interrupts need an interrupt number now if they are made critical),
1185 and enabled nesting of critical functions though not for gbz80
1186 (genCritical, genEndCritical): added functions
1187 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1188 * src/z80/mappings.i: added "ei" to all mappings

1200 the left operand is shorter than the result (c* = lit-c* + int),
1202 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1205 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1207 * src/.version: increased version number to 2.5.5
1208 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1209 linking is done manually in pic16 port's _linkEdit,
1210 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1211 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1212 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1213 allocate asmop as AOP_ACC,
1214 (aopForRemat): added parameter 'bool result' in function declaration,
1215 (pic16_aopGet): return AOP_ACC when accessing WREG,
1216 (pic16_popGetTempReg): minor modification,

1227 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1228 call to allocReg, not by manually allocating a new one,
1229 (pic16_assignRegisters): now before going through the register
1230 allocating functions mark all registers as free. This eliminates some
1231 side effects resulting from peephole parser done earlier in the backbone

1291 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1292 which dumps before the function entry point a data byte which represents
1293 the number of the local variables used by the specified function, added
1294 'xinst' for initial support for Extended Instruction Support,
1295 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1296 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1297 port->fun_prefix anymore (may change later),
1298 (genFunction, genEndFunction): do not store/restore local registers for
1299 _main (this should take care the --main-return command line option in
1301 (genOr): removed some legacy pic-port instructions,
1302 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1303 performing operations with SFR's causes data to be written more than
1304 once to each SFR. Perhaps SFRs should be handled in special cases...
1305 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1307 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1308 into account for stack starting position,

1312 (deassignLRs): *** perhaps the most important change, old 'for' code
1313 (commented out for reference), didn't account for some registers which
1314 were left marked 'not free' after a pointer operation. The change
1315 reduces register usage a lot in some cases
1317 2006-03-04 Borut Razem <borut.razem AT siol.net>

3584 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3586 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3588 * src/SDCCglobal.h (struct options),
3590 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3591 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3592 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3593 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3594 always available in leading double underscore form. The C99 support is
3595 mostly missing, but it's a start.
3596 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3597 reserved identifier "__data".
3599 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3675 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3677 * device/lib/printf_large.c: removed inline assembly for portability and
3678 readability. Use printf_fast if speed or size are more important.
3679 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3680 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3682 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3684 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3685 prevent compiler warning
3687 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3689 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3690 moved to level 0 and declared as static. Also they are explicit
3691 placed in access bank. This was necessery because some times they
3692 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3693 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3694 optimizations. Currently only compare to unsigned char is implemented,
3695 * src/pic16/gen.c: added fReturnIdx array,
3696 * (struct resolvedIfx) is moved to gen.h and made public,
3697 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3698 * (aopForSym): added an optimization to directly store in stack of
3699 the operand of a SEND iCode,
3700 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3701 but as registers instead (AOP_REG) using the fReturnIdx array,
3702 * (pic16_freeAsmop): remove the freed register from the
3703 _G.sregsAlloc field,
3704 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3705 a compare of 'WREG',
3706 * (pic16_popGetTempRegCond): changed function prototype, now
3707 function takes also a bitVector argument v which holds the current
3708 set of registers that are allocated for stack access by aopForSym,
3709 registers allocated in aopForSym for accessing stack symbols are not
3710 any more part of the functions usedRegs field,
3711 * (genCall): some times aopOp is called for a stack variable to be
3712 send, aopForSym might perform the push, if this is true make sure
3713 that genCall doesn't push the variable twice by testing _G.resDirect,
3714 * (genFunction): changed testing for unspecified interrupt number
3715 from 256 to INTNO_UNSPEC,
3716 * modified selection scheme of frame pointer generation. Previously
3717 if function did use local registers a frame pointer was generated,
3718 now a frame pointer is generated only if function has arguments
3719 (that need PLUSW2 register access), or has stack arguments, or the
3720 compiler is not instructed to omit the frame pointer,
3721 * (genEndFunction): before restoring local registers that were saved
3722 in the function preamble, also restore the registers that *might*
3723 have been allocated for stack access,
3724 * (genRet): removed some old comments,
3725 * (genCmp, the active (RN's) version): added a call to the
3726 pic16_genCmp_special function to perform the compare with a more
3727 robust and optimized way,
3728 * (genInline): a feature has been added in inline code generation,
3729 which allows a wildcard variable substitution when writing inline
3730 assembly. Code is incomplete and experimental therefore undocumented,
3731 * (genCast): changed order of aopOp for result and right to allow
3732 aopForSym to directly load the result if possible,
3733 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3734 perform an optimized compare on some selected special occasions,
3735 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3736 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3737 generate an IVT any more,
3738 * src/pic16/main.c (pic16_optionsTable): added command line option
3740 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3741 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3743 * src/pic16/NOTES: Raphael Neider added in list of active developers
3744 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3745 jumptable_end to prevent bug #,
3746 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3747 inCond and outCond fields,
3748 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3749 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3750 turn off register spilling,
3751 * (packRegsForOneUse): synced with other ports' versions although it
3752 is not used currently,
3753 * (pic16_packRegisters): added an optimization while reading
3754 structure bitfields, some registers may be saved (malloc code is
3755 decreased by 80 bytes)
3757 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3759 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3760 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3761 this can be optimized more?
3763 2005-03-10 Raphael Neider <rneider AT web.de>
3765 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3766 genNearPointerGet): (hopefully) fixed access to bitfields via
3767 pointers (p->bitN = x; and x = p->bitN; failed)
3769 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3813 to keep the correct label reference count when adding/removing references
3814 to labels. A peephole file using this is appended to patch #1144962.

4401 Adding support for replacing ljmps with sjmps in jumptables
4402 generated for switch statements. For now you need to set the
4403 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4404 Now 4 algorithms for mcs51 jumptable generation are used:
4405 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4406 addresses loaded pc-relative for up to 112 cases and stack-pushing
4407 target addresses loaded with offset from dptr for up to 256 cases.
4409 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4410 * src/mcs51/main.c: adapted constants for switch table generation

4434 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4435 to call when a stack overflow occurs,
4436 * (malloc.h): added CVS Id tag,
4437 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4439 * added libc directory. The current version of LibC contains string
4440 functions, ctype functions and macros and some functions of the
4441 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4442 be extensively tested in the future. Standard disclaimer here.
4443 Library is not automatically build yet. But one can build it by
4444 invoking 'make' inside the libc directory.
4445 * added ADC library under libio. Preliminary version yet.
4447 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4454 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4455 * (pic16_storeForReturn): optimized return of 0,
4456 * (genCmp): experimental code for new genCmp which uses PIC18's
4457 special compare&skip instructions. Initial tests fail some times
4458 with variables grater than 1 byte in size, so new code is disabled,
4459 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4461 * (genCast): began a fix to optimize the casting of a bit to another
4462 bit, now assigning a bitfield to another bitfield will fail, sorry,
4463 * src/pic16/main.c: disabled the use of lr-support feature,
4464 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4467 bits with offset (case PO_GPR_BIT),
4468 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4470 * (isBankInstruction): modified to return 0 for no banking instruction,
4471 and 1 for banking instruction,
4472 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4473 caused stop processing pCodes after a inline assembly block,
4474 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4475 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4476 registers when it shouldn't,
4477 * src/pic16/ralloc.c (allocReg): add preliminary support for
4478 supporting a limited set of temporary registers,
4480 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4482 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4483 genDataPointerSet): ensure assignments always copy in MSB to LSB
4485 (loadRegFromAop): recognize CLRH optimization,
4486 (genFunction): optimize RECEIVE iCodes in reentrant functions
4488 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4490 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7417 * src/pic/glue (pic14emitRegularMap),
7418 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7420 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7422 * src/pic/pcode.c (PCodeID): commented out left over debug code
7424 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7426 * support/valdiag/tests/overflow.c: added shift tests
7434 * src/pic/pcodepeep.c,
7435 * src/pic/pcoderegs.c,
7437 * src/pic/ralloc.h: applied patch from Slade Rich;
7438 added support for multiple code pages and multiple RAM banks on the
7439 PIC 14 port. The ASM files now no longer simply assume all the
7440 code / RAM are in the same page / bank. This means the linker can
7441 safely allocate code/RAM of separate ASM files to different pages/banks.
7442 * doc/sdccman.lyx: added Slade's tips
7443 * src/mcs51/peeph.def: fixed bug #880768

7452 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7455 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7456 strtof is not part of C89 and isn't included with Mac OS X.
7458 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7460 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7485 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7487 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7488 loaded with the linker search paths (-L arguments) and the libraries
7489 to be linked with the current source (-l arguments). Changes
7490 currently will affect only the pic16 port.
7491 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7492 include path the port specific paths and port specific libraries,
7493 * gplink command now contains the $3 argument,
7494 * src/pic16/device.h,
7495 * src/pic16/device.c,: structure PIC_device is made public and
7496 renamed to PIC16_device, the same for variable Pics which is renamed
7497 to Pics16. Updated all references to them.
7498 * src/pic16/glue.c (pic16glue): corrected bug with code
7499 initialization which bypassed the variable initializations block.
7501 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7502 COMPILE_FLAGS and added the --nostdinc option
7504 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7511 Documenting changes from previous commits.
7512 * configure.in (version 1.56),
7513 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7514 when generating output files to configure the pic16 library,
7515 but now I've commented it out, since gputils aren't installed in the
7516 SF compile farm, so library won't compile
7518 * device/lib/Makefile.in (version 1.56): initially I've added in
7519 target 'all' the prerequestive 'model-pic16' so it compiled the
7520 pic16 library, but now I've commented it out for the same reasons
7522 * added targets 'model-pic16' and 'objects-pic16' to compile the
7524 * added target 'port-specific-objects-pic16' to handle the
7525 generated libraries and copy them into the build/ directory
7526 * added target 'clean-intermediate-pic16' to clean intermediate
7527 files into pic16 directory
7528 * in target 'installdirs' added line to create directory pic16 in
7529 the installation path

7532 added lines to copy all header files to installation path,
7533 * in target 'installdirs' added line create directory for pic16
7534 headers in the installation path

7549 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7550 option so that it actually works. Made it specific to the z80, since
7551 the gbz80 doesn't have these kinds of I/O ports.
7553 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7555 * device/include/z180.h,

7577 Mainly changes to support compilation of the device libraries
7578 * src/pic16/device.c: stack is allocated via symbol and not
7579 via literal number. The symbol is placed in the corresponding
7580 position of the data ram
7581 * (pic16_dump_section): relocatable and absolute uninitialized
7582 data are now emitted in sorted order to reduce section naming,
7583 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7584 weren't marked as being in the access bank,
7586 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7588 Added portion of GNU PIC Library under the directory
7589 device/include/pic16 and device/lib/pic16. These files
7590 contain the declarations of SFRs for the PIC18Fxx2 devices.
7591 The directory is initialized via configure from toplevel.
7593 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7595 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7621 all over. Telling LaTeX to be less strict with word spacing
7622 to better keep the right margin. Changed some notes about
7623 maintainance of the ports in section 3.2.1 - is it OK like this?
7625 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7663 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7665 * src/pic16/peeph.def: all peepholes with movff are commented out,
7666 because there is a problem in the pcode peep optimizer,
7667 * src/pic16/ralloc.c: the register allocator can now reuse local

7787 * support/valdiag/Makefile,
7788 * support/valdiag/valdiag.py,
7789 * support/valdiag/tests/*

7819 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7821 PIC16 port related changes:
7822 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7823 added variable stackPos,
7825 * gen.c: genCall, assignResultValue: added support for
7826 pushing/retrieving function parameters to/from stack,
7827 genFunction,genEndFunction: setup stack frame for the
7829 genAddrOf: will be changed according to bug 863624
7831 * added files genutils.c and genutils.h which contain gen*
7832 debugged and optimised functions extracted from gen.c
7834 * glue.c: added variable 'externs' which holds extern symbols,
7835 pic16emitRegularMap: is modified to properly handle relocatable
7836 symbols under the new scheme,
7837 pic16createInterruptVect: is modified
7838 pic16printPublics: is modified to emit 'global' assembler directives,
7839 added pic16_printExterns to print extern symbols,
7840 pic16glue: initializes stack/frame pointer in the beginning of
7841 the assembly output. Temporary hack, will be corrected later,
7842 because gplink yet does not support stack and SDCC does not
7843 yet support a type of crt0.o object to create the final binary.
7845 * Removed many lines that contain 8051 legacy code.
7846 * The code is finally placed under a 'code' directive.
7847 * Added port specific options.
7849 * _process_pragma: simplified since now we do not need *special*
7850 include file to define SFR registers. But a separate header
7851 will be needed. This will be developed later.
7852 * _pic16_parseOptions: added, parses port specific options:
7853 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7854 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7855 --preplace-udata-with=
7857 * _pic16_setDefaultOptions: modified to initialize section names,
7858 but hack is temporarly out of order since it needs improvement.
7859 * _pic16_genAssemblerPreamble: configuration words are emitted by
7860 their address instead of their name. This part is incomplete and
7861 supports only the 18Fxx2 devices. Other devices will emit an error
7862 during assembly since they do not contain the same set of config
7864 * _pic16_genIVT: is modified,
7866 * pcode.c: added definitions for some hardware registers that are needed
7868 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7869 All PCI entries are updated. Now LFSR is supported.
7870 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7871 * added pic16_newpCodeOpLit2 to support instructions with
7872 two literal arguments
7873 * pic16_pCode2str: corrected code that emits assembler instructions
7874 with two literal operands and those that have an access bit modifier
7875 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7876 this fixes a bug which caused some labels to be lost, when an
7877 assembler directive was added, i.e. banksel,
7878 * pic16_FixRegisterBanking: improved logic that causes the insertion
7880 * InlineFunction: functions that are called once, are not any more
7881 inlined. This can be a port option in the future,
7883 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7885 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7886 hold the corresponding uninitialized symbols,
7887 * pic16_allocProcessorRegister: registers have explicit marked the
7889 * pic16_allocInternalRegister: registers are explicit marked as
7891 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7892 processing list, so bit registers were lost,
7895 * ralloc.h: added field 'accessBank' and original symbol operand
7896 in register definition,
7897 * removed the field isMapped from register definition,
7899 ** Several functions have been removed from various sources:
7900 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7901 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7902 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7903 pic16_assignRelocatableRegisters
7905 ** others have been introduced:
7906 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7907 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7909 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7911 * support/scripts/inc2h.pl: changed definition of BIT_AT
7912 to emit 'sbit at' instead of 'bit at'. This was a request.
7914 PIC16 port related preliminary changes:
7915 * gen.c: prefixed function popRegFromString with
7916 pic16_ and all references to it corrected
7917 * pcode.c: all pic16_pc_* hardware registers prefixed
7918 with underscore (_),
7919 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7920 * ralloc.c: newReg(): when register is REG_SFR then
7921 set address to rIdx,
7922 pic16_allocProcessorRegister(): marks register wasUsed=0
7923 pic16_writeUsedRegs(): added a call to assign processor
7924 registers via pic16_assignFixedRegisters
7926 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7928 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7929 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7930 variables in unused register banks. Also the SSEG is placed
7931 wherever there is enough space for it, and IDATA can be anywhere
7932 in internal RAM. For now compile using -Wl-Y[stack_size].
7933 The mem file is different for this option as well, since it
7934 makes no sense of talking about DSEG lenght.
7936 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7938 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8183 * src/SDCCast.c (decorateType): disabled a transformation I added in
8184 revision 1.188 (access to fields of a structure at an absolute address);
8185 it breaks with bitfields, extern declarations, and gcse analysis.
8186 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8187 could be assigned through a pointer, so don't complain.

8911 reported in bug #800609
8913 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8915 * Top header beautifications in src/pic16 directory:
8916 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8917 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8918 pcoderegs.h, ralloc.c, ralloc.h
8919 * main.c: added top header and GPL license notice
8920 * pcode.c: fixed the if-conditional warning
8922 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8924 * device/lib/_mullong.c: replaced int by short for gcc
8926 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8928 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8929 and JUMPTABLE iCodes properly now (worked by accident before)
8930 * src/mcs51/gen.c (leftRightUseAcc),
8931 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8932 iCode properly now. Use getSize instead of nRegs since a & b
8933 aren't part of the nRegs tally.
8935 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8937 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8938 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8939 before instructions that use the _STATUS register
8941 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8943 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8944 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8945 fetching of the pointer
8946 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8947 copied from genNearPointerSet()
8948 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8949 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8950 If they pop r0/r1 they must be called in the opposite order than aopOp().
8951 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8952 (resp. --stack-auto), prepared for --xstack
8954 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8958 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8960 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8961 these ports have their own __sdcc_external_start()
8963 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8965 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8966 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8967 type for bits was changed. It resulted in bit variables becoming
8968 global, which is not permitted in PIC 14 assembly output.
8970 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8972 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8974 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8976 Z80 and MCS51 linkers complaint if a public symbol is defined
8977 in more than one library module:
8981 * as/mcs51/Makefile.in
8983 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8985 A few small changes that speed up the peephole optimizer.
8989 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8991 Try to make the peephole optimizer smarter by maintaining
8992 an association between the assembly source code and the
8993 iCodes that originated them. Put this information to use
8994 with a new peephole rule condition "notVolatile" so that
8995 the rules can be aggressive yet still safe.
9000 * src/mcs51/peeph.def
9002 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9006 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9007 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9008 if the left or right operand symbols have the accuse flag set.
9010 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9012 Changed the type of the result of the ! (NOT) operator to char;
9013 previously it returned the same type as the source. This allows
9014 us to eliminate all the genFloatNot functions (all of its target
9015 implementations were very buggy) since !float can use the same
9018 * src/SDCCicode.c (ast2iCode): ! returns char
9019 * src/mcs51/gen.c (genNot, genNotFloat),
9020 * src/ds390/gen.c (genNot, genNotFloat),
9021 * src/z80/gen.c (genNot, genNotFloat),
9022 * src/pic/gen.c (genNot, genNotFloat),
9023 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9025 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9027 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9028 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9029 during interrupts. Ensure WSAVE is located at a shared bank address.
9030 2. Fixed page selection in some places
9031 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9032 the registers name strings.
9033 4. Fixed "signed / unsigned compare" compiler warnings.
9034 5. The PIC port manages its own allocation of the general purpose
9035 registers, but makes no attempt to reuse them. As a result when
9036 compiling it soon runs out of general purpose registers. Some
9037 additional code was added to the files pcode.c and device.c to walk
9038 through the function call tree and rename the registers so that they
9048 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9049 genPlus() & genMinus() when the result is the same as left or right

9055 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9057 Made bitfield a distinct type from bit so that bitfields
9058 convert as per ANSI C and bits retain their traditional
9059 boolean style behaviour. Implemented bitfield support in
9067 * src/ds390/gen.c: bit v bitfield split
9068 * src/z80/gen.c: New support for bitfields
9069 * support/regression/tests/bitfields.c: reenabled z80,
9072 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9074 Rules 246.x, 247.x relate to bitfields, the others speed up
9075 access to xdata mapped I/O devices.
9077 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9079 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9081 Cleaned up genPackBits and genUnpackBits and added two helper
9082 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9083 for literal assignments in genPackBits (thanks to Frieder for
9089 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9091 Fixed bug #748310 (pointer to function type mishandled when the
9092 function name is omitted). Also fixed a SIGSEGV when a function
9093 attribute (reentrant, etc) is used on a non-function or on a
9094 function but misplaced before the parameter list.
9096 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9098 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9099 * support/Util/SDCCerr.h,
9100 * support/Util/SDCCerr.c: Added func attr misuse error msg
9102 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9104 Fixed bug #787649 by anonymous
9105 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9121 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9123 Made the constant following the "interrupt" keyword optional. If
9124 omitted, the function will not automatically be given an entry
9125 in the interrupt vector table (similar to #pragma NOIV, but
9126 less syntacticly kludgy). The interrupt number is also now
9127 range checked. Also fixed a bug in the high order bit example
9134 * support/Util/SDCCerr.c
9135 * support/Util/SDCCerr.h
9138 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9141 * src/SDCCicode.c (operandOperation): rewritten some ops
9142 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9143 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9145 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9146 be re-activated by defining REDUCE_LITERALS)
9147 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9148 unsigned, but are signed by default
9149 * src/SDCCval.c (constVal): rearranged
9150 * src/SDCCval.c (valMod): preliminary fix
9151 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9194 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9195 * src/SDCCval.c (valDiv, valMod): fixed signdness
9196 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9197 signedness of modulo, left and right shift

9603 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9604 the regression tests I'm not brave enough to enable 245.b, 245.c
9605 * doc/sdccman.lyx: added latex preamble for hyperref package.
9606 Using pdflatex this will give you a hyperlinked pdf file with
9607 bookmarks. (prepend '%' before /usepackage if this breaks something)

9645 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9647 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9648 it can be defined with CFLAGS when running configure
9649 * src/SDCCmain.c: fixed compiling + linking with object files
9651 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9654 added --disable-pic16-port
9655 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9656 * src/SDCCmain.c: linkOptions is changed to set *,
9657 added if/endif conditional macros to remove options help
9658 messages from optionsTable when a port is not configured, added
9659 support for the PIc16 port in the ports table, when executing
9660 the compiler with no port specified on command line, a default
9661 port is selected with the new macro DEFAULT_PORT which is
9662 defined in port.h, in setDefaultOptions() linkOptions is removed
9663 from initialization assignment, since now it is a set,
9664 parseCmdLine uses setParseWithComma for linkOptions, in
9665 linkEdit() linkOptions are accessed with new function indexSet()
9666 which returns the i'th item of a set variable. See SDCCset.c, in
9667 linkEdit() when calling buildCmdLine(), added linkOptions as
9668 last argument. Now users can pass arguments to gplink via the
9669 -Wl option, main() uses pic16glue() to glue up pic16 programs

9681 * src/pic16/glue.c: commented out some error producing lines
9682 * src/pic16/main.c: __config directives are commented out to stop
9683 gpasm complaining and test the linkage with gplink, _linkCmd and
9684 _asmCmd changed to be more gplink and gpasm friendly
9685 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9686 produced an error when parsed, peep rule 12 is added to utilize
9687 movff, but it is commented out since the pCode does not support
9688 yet a command with 2 address arguments
9690 2003-05-18 <johan AT balder>
9692 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9693 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9719 2003-05-11 Borut Razem <borut.razem AT siol.net>
9721 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9722 the path of bin directory, so that PATH is the only env. variable, which has to be set
9723 in case of standard installation.
9724 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10796 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10799 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10800 area BSEG. Also moves, if possible, the DATA area down into the internal
10801 ram so more space is available.
10803 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10806 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10807 not bytes. Function summary() which creates a memory usage summary
10808 file with extension .mem. Reports of overlaping stack and small stack
10809 size. If the space for the stack is less than 16 bytes aslink trows a
10812 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10813 the 8051. Option 'y' for memory summary output file.
10815 Changes to sdcc (All the changes are marked with 'JCF'):
10817 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10819 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10820 overlaying area for it (uses RegBankUsed[4]).
10822 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10823 bank zero as used by default. By default aslink locates the stack
10824 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10825 the creation of the .mem file. Delegates the allocation of data area
10826 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10827 the begining of the stack area to aslink.
10829 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10830 glue() in SDCCglue.c creates an area for it.
10832 2002-09-03 Borut Razem <borut.razem AT siol.net>
10833 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10834 sdcc/src/pic/glue.c:
10835 introduced atexit() handler for teporay files removal in case of
10836 errors, assertions, ...
10838 2002-08-29 Borut Razem <borut.razem AT siol.net>
10839 * sdcc/support/cpp2/auto-host_vc_in.h:
10840 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10841 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10842 Maybe there is a similar problem with BORLANDC? It should be checked!
10844 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10845 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10846 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10847 was not executed, and the compiler (cl) launched a warning:
10848 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10850 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10851 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10853 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10854 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10856 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10857 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10858 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10859 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10860 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10861 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10862 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10863 - added Release configuration in VS projects
10864 - review of compiler an linker options
10865 - VC .exe files are generated in bin_vc directory, not to interfere
10866 with binaries generated from other projects (cygwin, mingw, bcc ...)
10868 * sdcc/src/yacc.dsp: added
10870 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10871 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10872 and insert the version number definitions from .version
10874 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10876 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10877 added - genarate auto-host.h using auto-host_vc_in.h as template
10880 removed from CVS, generated automatically
10882 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10883 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10885 2002-08-11 Borut Razem <borut.razem AT siol.net>
10886 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10888 2002-08-10 Borut Razem <borut.razem AT siol.net>
10889 * src/SDCCmain.c (main):
10890 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10891 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10892 The consequence was that some temporary files were not removed.
10895 unification of code in functions tempfilename() and tempfile():
10896 function tempnam() is defined in Visual Studio 6.0 and .NET
10898 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10900 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10901 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10902 - removed compiler command line option /WX: Treats all warnings as errors
10903 - update a list of source files, included into the project
10905 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10906 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10907 changed project type to Generic Project so that can be correcly converted to VS.NET project
10909 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10911 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10913 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10915 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10916 added return 0 statements after assert() to make compiler happy
10918 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10919 added newline in the def file to keep MSC compiler satisfied
10921 * sdcc/src/z80/gen.c:
10922 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10923 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10924 - solved MSC error in function aopDump()
10926 * sdcc_vc.h: define PREFIX as "\\sdcc"
10928 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10929 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10966 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10968 2002-03-28 Johan Knol <johan AT balder>
10970 * src/SDCCval.c: fixed bug #532436
10972 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10974 Added "char *Processor" field to the port structure.
10977 Added -p option. Allows port dependent processor to be specified.
10980 Initialized the new field char *Processor field to NULL in all ports
10983 Compiler generated registers for interrupt context saving
10984 were not getting allocated.
10986 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

11101 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11103 * sdcc/src/SDCCloop.c:
11104 Previous fix was not good. basic blocks that have "break" or "return" are
11105 not really partof a loop , but live ranges used in these blocks should
11106 be live thru the entire loop, so set partOfLoop but don't add them to
11109 2002-02-21 <johan AT FRIJA>
11111 * src/SDCCcse.c: fixed bug #514308
11113 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
