881 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
883 Enabled VPATH feature: changed nearly all Makefiles (149 files).
884 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
886 One basic decision: e.g. src/clean.mk includes further files. In order
887 to make this work there are two solutions:
888 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
889 run configure on them. This way they can use
890 'include $(srcdir)/port-clean.mk'
891 - always include clean.mk by the Makefile at the same level. To avoid
892 that `make clean` tries to include and build Makefile.dep the
893 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
894 implemented, because now even `make uninstall` doesn't create
895 Makefile.in. clean.mk could be eliminated by pasting it in
898 * debugger/mcs51/Makefile.in: build own objects from library sources
899 (SLIB, SDCC) in current directory
901 * configure, configure.in: renamed --disable-device-lib-build in
902 --disable-device-lib; added --enable-doc, the required tools are
903 searched by configure; added result message; the toolchain for the
904 belonging ports are now only built, if the port is enabled.
906 * support/regression/*: all output is written in directory gen, because
907 the fwk and ports directories don't livet in the build tree using vpath
909 * doc/sdccman.lyx: renamed --disable-device-lib-build to
910 --disable-device-lib, added --enable-doc, added section VPATH
912 * sim/ucsim/configure.in,
913 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
914 z80 are enabled by default
916 2006-04-24 Raphael Neider <rneider AT web.de>
918 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
919 to config word, "pic14_"-prefixed some extern functions
920 (pic14_emitConfigWord): emit __config directive(s) if assignment to
921 config word has been found
922 * src/pic/device.h: added prototypes
923 * src/pic/pcode.c: added "pic14_"-prefix where needed

926 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
928 (pic14emitRegularMap): ignore config words,
929 (pic14createInterruptVect): moved generating __config directives away
930 (picglue): have __config directives emitted
932 2006-04-24 Borut Razem <borut.razem AT siol.net>
934 * doc/Makefile: sync with nightly build makefile
936 2006-04-24 Raphael Neider <rneider AT web.de>

1164 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1166 * src/mcs51/gen.c (genCall): fixed bug 1457608
1168 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1187 implemented patch 1120823 Thanks to Willy De la Court (normal
1188 interrupts need an interrupt number now if they are made critical),
1189 and enabled nesting of critical functions though not for gbz80
1190 (genCritical, genEndCritical): added functions
1191 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1192 * src/z80/mappings.i: added "ei" to all mappings

1206 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1209 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1211 * src/.version: increased version number to 2.5.5
1212 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1213 linking is done manually in pic16 port's _linkEdit,
1214 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1215 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1216 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1217 allocate asmop as AOP_ACC,
1218 (aopForRemat): added parameter 'bool result' in function declaration,
1219 (pic16_aopGet): return AOP_ACC when accessing WREG,
1220 (pic16_popGetTempReg): minor modification,

1231 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1232 call to allocReg, not by manually allocating a new one,
1233 (pic16_assignRegisters): now before going through the register
1234 allocating functions mark all registers as free. This eliminates some
1235 side effects resulting from peephole parser done earlier in the backbone
1237 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1287 2006-03-06 Borut Razem <borut.razem AT siol.net>
1289 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1290 made the linker quiet
1292 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1295 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1296 which dumps before the function entry point a data byte which represents
1297 the number of the local variables used by the specified function, added
1298 'xinst' for initial support for Extended Instruction Support,
1299 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1300 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1301 port->fun_prefix anymore (may change later),
1302 (genFunction, genEndFunction): do not store/restore local registers for
1303 _main (this should take care the --main-return command line option in
1305 (genOr): removed some legacy pic-port instructions,
1306 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1307 performing operations with SFR's causes data to be written more than
1308 once to each SFR. Perhaps SFRs should be handled in special cases...
1309 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1311 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1312 into account for stack starting position,

1314 --extended or -y for Extended Instruction Support,
1315 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1316 (deassignLRs): *** perhaps the most important change, old 'for' code
1317 (commented out for reference), didn't account for some registers which
1318 were left marked 'not free' after a pointer operation. The change
1319 reduces register usage a lot in some cases
1321 2006-03-04 Borut Razem <borut.razem AT siol.net>
1323 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3594 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3595 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3596 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3597 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3598 always available in leading double underscore form. The C99 support is
3599 mostly missing, but it's a start.
3600 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3601 reserved identifier "__data".

3679 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3681 * device/lib/printf_large.c: removed inline assembly for portability and
3682 readability. Use printf_fast if speed or size are more important.
3683 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3684 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3686 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3688 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3689 prevent compiler warning
3691 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3693 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3694 moved to level 0 and declared as static. Also they are explicit
3695 placed in access bank. This was necessery because some times they
3696 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3697 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3698 optimizations. Currently only compare to unsigned char is implemented,
3699 * src/pic16/gen.c: added fReturnIdx array,
3700 * (struct resolvedIfx) is moved to gen.h and made public,
3701 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3702 * (aopForSym): added an optimization to directly store in stack of
3703 the operand of a SEND iCode,
3704 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3705 but as registers instead (AOP_REG) using the fReturnIdx array,
3706 * (pic16_freeAsmop): remove the freed register from the
3707 _G.sregsAlloc field,
3708 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3709 a compare of 'WREG',
3710 * (pic16_popGetTempRegCond): changed function prototype, now
3711 function takes also a bitVector argument v which holds the current
3712 set of registers that are allocated for stack access by aopForSym,
3713 registers allocated in aopForSym for accessing stack symbols are not
3714 any more part of the functions usedRegs field,
3715 * (genCall): some times aopOp is called for a stack variable to be
3716 send, aopForSym might perform the push, if this is true make sure
3717 that genCall doesn't push the variable twice by testing _G.resDirect,
3718 * (genFunction): changed testing for unspecified interrupt number
3719 from 256 to INTNO_UNSPEC,
3720 * modified selection scheme of frame pointer generation. Previously
3721 if function did use local registers a frame pointer was generated,
3722 now a frame pointer is generated only if function has arguments
3723 (that need PLUSW2 register access), or has stack arguments, or the
3724 compiler is not instructed to omit the frame pointer,
3725 * (genEndFunction): before restoring local registers that were saved
3726 in the function preamble, also restore the registers that *might*
3727 have been allocated for stack access,
3728 * (genRet): removed some old comments,
3729 * (genCmp, the active (RN's) version): added a call to the
3730 pic16_genCmp_special function to perform the compare with a more
3731 robust and optimized way,
3732 * (genInline): a feature has been added in inline code generation,
3733 which allows a wildcard variable substitution when writing inline
3734 assembly. Code is incomplete and experimental therefore undocumented,
3735 * (genCast): changed order of aopOp for result and right to allow
3736 aopForSym to directly load the result if possible,
3737 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3738 perform an optimized compare on some selected special occasions,
3739 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3740 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3741 generate an IVT any more,
3742 * src/pic16/main.c (pic16_optionsTable): added command line option
3744 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3745 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3747 * src/pic16/NOTES: Raphael Neider added in list of active developers
3748 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3749 jumptable_end to prevent bug #,
3750 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3751 inCond and outCond fields,
3752 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3753 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3754 turn off register spilling,
3755 * (packRegsForOneUse): synced with other ports' versions although it
3756 is not used currently,
3757 * (pic16_packRegisters): added an optimization while reading
3758 structure bitfields, some registers may be saved (malloc code is
3759 decreased by 80 bytes)
3761 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3763 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3764 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3765 this can be optimized more?
3767 2005-03-10 Raphael Neider <rneider AT web.de>
3769 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3770 genNearPointerGet): (hopefully) fixed access to bitfields via
3771 pointers (p->bitN = x; and x = p->bitN; failed)

4405 Adding support for replacing ljmps with sjmps in jumptables
4406 generated for switch statements. For now you need to set the
4407 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4408 Now 4 algorithms for mcs51 jumptable generation are used:
4409 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4410 addresses loaded pc-relative for up to 112 cases and stack-pushing
4411 target addresses loaded with offset from dptr for up to 256 cases.

4438 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4439 to call when a stack overflow occurs,
4440 * (malloc.h): added CVS Id tag,
4441 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4443 * added libc directory. The current version of LibC contains string
4444 functions, ctype functions and macros and some functions of the
4445 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4446 be extensively tested in the future. Standard disclaimer here.
4447 Library is not automatically build yet. But one can build it by
4448 invoking 'make' inside the libc directory.
4449 * added ADC library under libio. Preliminary version yet.

4458 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4459 * (pic16_storeForReturn): optimized return of 0,
4460 * (genCmp): experimental code for new genCmp which uses PIC18's
4461 special compare&skip instructions. Initial tests fail some times
4462 with variables grater than 1 byte in size, so new code is disabled,
4463 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4465 * (genCast): began a fix to optimize the casting of a bit to another
4466 bit, now assigning a bitfield to another bitfield will fail, sorry,
4467 * src/pic16/main.c: disabled the use of lr-support feature,
4468 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4471 bits with offset (case PO_GPR_BIT),
4472 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4474 * (isBankInstruction): modified to return 0 for no banking instruction,
4475 and 1 for banking instruction,
4476 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4477 caused stop processing pCodes after a inline assembly block,
4478 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4479 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4480 registers when it shouldn't,
4481 * src/pic16/ralloc.c (allocReg): add preliminary support for
4482 supporting a limited set of temporary registers,
4484 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4486 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4487 genDataPointerSet): ensure assignments always copy in MSB to LSB
4489 (loadRegFromAop): recognize CLRH optimization,
4490 (genFunction): optimize RECEIVE iCodes in reentrant functions
4492 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4494 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7421 * src/pic/glue (pic14emitRegularMap),
7422 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7424 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7426 * src/pic/pcode.c (PCodeID): commented out left over debug code
7428 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7430 * support/valdiag/tests/overflow.c: added shift tests
7438 * src/pic/pcodepeep.c,
7439 * src/pic/pcoderegs.c,
7441 * src/pic/ralloc.h: applied patch from Slade Rich;
7442 added support for multiple code pages and multiple RAM banks on the
7443 PIC 14 port. The ASM files now no longer simply assume all the
7444 code / RAM are in the same page / bank. This means the linker can
7445 safely allocate code/RAM of separate ASM files to different pages/banks.
7446 * doc/sdccman.lyx: added Slade's tips
7447 * src/mcs51/peeph.def: fixed bug #880768

7456 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7459 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7460 strtof is not part of C89 and isn't included with Mac OS X.
7462 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7464 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7489 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7491 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7492 loaded with the linker search paths (-L arguments) and the libraries
7493 to be linked with the current source (-l arguments). Changes
7494 currently will affect only the pic16 port.
7495 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7496 include path the port specific paths and port specific libraries,
7497 * gplink command now contains the $3 argument,
7498 * src/pic16/device.h,
7499 * src/pic16/device.c,: structure PIC_device is made public and
7500 renamed to PIC16_device, the same for variable Pics which is renamed
7501 to Pics16. Updated all references to them.
7502 * src/pic16/glue.c (pic16glue): corrected bug with code
7503 initialization which bypassed the variable initializations block.
7505 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7506 COMPILE_FLAGS and added the --nostdinc option
7508 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7513 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7515 Documenting changes from previous commits.
7516 * configure.in (version 1.56),
7517 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7518 when generating output files to configure the pic16 library,
7519 but now I've commented it out, since gputils aren't installed in the
7520 SF compile farm, so library won't compile
7522 * device/lib/Makefile.in (version 1.56): initially I've added in
7523 target 'all' the prerequestive 'model-pic16' so it compiled the
7524 pic16 library, but now I've commented it out for the same reasons
7526 * added targets 'model-pic16' and 'objects-pic16' to compile the
7528 * added target 'port-specific-objects-pic16' to handle the
7529 generated libraries and copy them into the build/ directory
7530 * added target 'clean-intermediate-pic16' to clean intermediate
7531 files into pic16 directory
7532 * in target 'installdirs' added line to create directory pic16 in
7533 the installation path
7535 * device/include/Makefile.in (version 1.11): in target 'install'
7536 added lines to copy all header files to installation path,
7537 * in target 'installdirs' added line create directory for pic16
7538 headers in the installation path

7553 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7554 option so that it actually works. Made it specific to the z80, since
7555 the gbz80 doesn't have these kinds of I/O ports.
7557 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7559 * device/include/z180.h,

7581 Mainly changes to support compilation of the device libraries
7582 * src/pic16/device.c: stack is allocated via symbol and not
7583 via literal number. The symbol is placed in the corresponding
7584 position of the data ram
7585 * (pic16_dump_section): relocatable and absolute uninitialized
7586 data are now emitted in sorted order to reduce section naming,
7587 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7588 weren't marked as being in the access bank,
7590 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7592 Added portion of GNU PIC Library under the directory
7593 device/include/pic16 and device/lib/pic16. These files
7594 contain the declarations of SFRs for the PIC18Fxx2 devices.
7595 The directory is initialized via configure from toplevel.
7597 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7599 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7625 all over. Telling LaTeX to be less strict with word spacing
7626 to better keep the right margin. Changed some notes about
7627 maintainance of the ports in section 3.2.1 - is it OK like this?
7629 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7667 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7669 * src/pic16/peeph.def: all peepholes with movff are commented out,
7670 because there is a problem in the pcode peep optimizer,
7671 * src/pic16/ralloc.c: the register allocator can now reuse local

7810 Bug reported from Jesus Calvino-Fraga
7812 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7814 * sdcc.spec: updated
7815 * device/include/Makefile.in: don't install CVS directories

7823 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7825 PIC16 port related changes:
7826 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7827 added variable stackPos,
7829 * gen.c: genCall, assignResultValue: added support for
7830 pushing/retrieving function parameters to/from stack,
7831 genFunction,genEndFunction: setup stack frame for the
7833 genAddrOf: will be changed according to bug 863624
7835 * added files genutils.c and genutils.h which contain gen*
7836 debugged and optimised functions extracted from gen.c
7838 * glue.c: added variable 'externs' which holds extern symbols,
7839 pic16emitRegularMap: is modified to properly handle relocatable
7840 symbols under the new scheme,
7841 pic16createInterruptVect: is modified
7842 pic16printPublics: is modified to emit 'global' assembler directives,
7843 added pic16_printExterns to print extern symbols,
7844 pic16glue: initializes stack/frame pointer in the beginning of
7845 the assembly output. Temporary hack, will be corrected later,
7846 because gplink yet does not support stack and SDCC does not
7847 yet support a type of crt0.o object to create the final binary.
7849 * Removed many lines that contain 8051 legacy code.
7850 * The code is finally placed under a 'code' directive.
7851 * Added port specific options.
7853 * _process_pragma: simplified since now we do not need *special*
7854 include file to define SFR registers. But a separate header
7855 will be needed. This will be developed later.
7856 * _pic16_parseOptions: added, parses port specific options:
7857 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7858 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7859 --preplace-udata-with=
7861 * _pic16_setDefaultOptions: modified to initialize section names,
7862 but hack is temporarly out of order since it needs improvement.
7863 * _pic16_genAssemblerPreamble: configuration words are emitted by
7864 their address instead of their name. This part is incomplete and
7865 supports only the 18Fxx2 devices. Other devices will emit an error
7866 during assembly since they do not contain the same set of config
7868 * _pic16_genIVT: is modified,
7870 * pcode.c: added definitions for some hardware registers that are needed
7872 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7873 All PCI entries are updated. Now LFSR is supported.
7874 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7875 * added pic16_newpCodeOpLit2 to support instructions with
7876 two literal arguments
7877 * pic16_pCode2str: corrected code that emits assembler instructions
7878 with two literal operands and those that have an access bit modifier
7879 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7880 this fixes a bug which caused some labels to be lost, when an
7881 assembler directive was added, i.e. banksel,
7882 * pic16_FixRegisterBanking: improved logic that causes the insertion
7884 * InlineFunction: functions that are called once, are not any more
7885 inlined. This can be a port option in the future,
7887 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7889 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7890 hold the corresponding uninitialized symbols,
7891 * pic16_allocProcessorRegister: registers have explicit marked the
7893 * pic16_allocInternalRegister: registers are explicit marked as
7895 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7896 processing list, so bit registers were lost,
7899 * ralloc.h: added field 'accessBank' and original symbol operand
7900 in register definition,
7901 * removed the field isMapped from register definition,
7903 ** Several functions have been removed from various sources:
7904 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7905 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7906 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7907 pic16_assignRelocatableRegisters
7909 ** others have been introduced:
7910 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7911 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7913 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7915 * support/scripts/inc2h.pl: changed definition of BIT_AT
7916 to emit 'sbit at' instead of 'bit at'. This was a request.
7918 PIC16 port related preliminary changes:
7919 * gen.c: prefixed function popRegFromString with
7920 pic16_ and all references to it corrected
7921 * pcode.c: all pic16_pc_* hardware registers prefixed
7922 with underscore (_),
7923 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7924 * ralloc.c: newReg(): when register is REG_SFR then
7925 set address to rIdx,
7926 pic16_allocProcessorRegister(): marks register wasUsed=0
7927 pic16_writeUsedRegs(): added a call to assign processor
7928 registers via pic16_assignFixedRegisters
7930 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7932 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7933 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7934 variables in unused register banks. Also the SSEG is placed
7935 wherever there is enough space for it, and IDATA can be anywhere
7936 in internal RAM. For now compile using -Wl-Y[stack_size].
7937 The mem file is different for this option as well, since it
7938 makes no sense of talking about DSEG lenght.
7940 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7942 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8187 * src/SDCCast.c (decorateType): disabled a transformation I added in
8188 revision 1.188 (access to fields of a structure at an absolute address);
8189 it breaks with bitfields, extern declarations, and gcse analysis.
8190 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8191 could be assigned through a pointer, so don't complain.

8915 reported in bug #800609
8917 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8919 * Top header beautifications in src/pic16 directory:
8920 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8921 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8922 pcoderegs.h, ralloc.c, ralloc.h
8923 * main.c: added top header and GPL license notice
8924 * pcode.c: fixed the if-conditional warning
8926 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8928 * device/lib/_mullong.c: replaced int by short for gcc
8930 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8932 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8933 and JUMPTABLE iCodes properly now (worked by accident before)
8934 * src/mcs51/gen.c (leftRightUseAcc),
8935 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8936 iCode properly now. Use getSize instead of nRegs since a & b
8937 aren't part of the nRegs tally.
8939 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8941 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8942 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8943 before instructions that use the _STATUS register
8945 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8947 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8948 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8949 fetching of the pointer
8950 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8951 copied from genNearPointerSet()
8952 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8953 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8954 If they pop r0/r1 they must be called in the opposite order than aopOp().
8955 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8956 (resp. --stack-auto), prepared for --xstack
8958 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8962 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8964 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8965 these ports have their own __sdcc_external_start()
8967 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8969 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8970 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8971 type for bits was changed. It resulted in bit variables becoming
8972 global, which is not permitted in PIC 14 assembly output.
8974 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8976 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8978 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8980 Z80 and MCS51 linkers complaint if a public symbol is defined
8981 in more than one library module:
8985 * as/mcs51/Makefile.in
8987 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8989 A few small changes that speed up the peephole optimizer.
8993 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8995 Try to make the peephole optimizer smarter by maintaining
8996 an association between the assembly source code and the
8997 iCodes that originated them. Put this information to use
8998 with a new peephole rule condition "notVolatile" so that
8999 the rules can be aggressive yet still safe.
9004 * src/mcs51/peeph.def
9006 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9010 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9011 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9012 if the left or right operand symbols have the accuse flag set.
9014 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9016 Changed the type of the result of the ! (NOT) operator to char;
9017 previously it returned the same type as the source. This allows
9018 us to eliminate all the genFloatNot functions (all of its target
9019 implementations were very buggy) since !float can use the same
9022 * src/SDCCicode.c (ast2iCode): ! returns char
9023 * src/mcs51/gen.c (genNot, genNotFloat),
9024 * src/ds390/gen.c (genNot, genNotFloat),
9025 * src/z80/gen.c (genNot, genNotFloat),
9026 * src/pic/gen.c (genNot, genNotFloat),
9027 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9029 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9031 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9032 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9033 during interrupts. Ensure WSAVE is located at a shared bank address.
9034 2. Fixed page selection in some places
9035 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9036 the registers name strings.
9037 4. Fixed "signed / unsigned compare" compiler warnings.
9038 5. The PIC port manages its own allocation of the general purpose
9039 registers, but makes no attempt to reuse them. As a result when
9040 compiling it soon runs out of general purpose registers. Some
9041 additional code was added to the files pcode.c and device.c to walk
9042 through the function call tree and rename the registers so that they
9052 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9053 genPlus() & genMinus() when the result is the same as left or right

9059 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9061 Made bitfield a distinct type from bit so that bitfields
9062 convert as per ANSI C and bits retain their traditional
9063 boolean style behaviour. Implemented bitfield support in
9071 * src/ds390/gen.c: bit v bitfield split
9072 * src/z80/gen.c: New support for bitfields
9073 * support/regression/tests/bitfields.c: reenabled z80,
9076 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9078 Rules 246.x, 247.x relate to bitfields, the others speed up
9079 access to xdata mapped I/O devices.
9081 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9083 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9085 Cleaned up genPackBits and genUnpackBits and added two helper
9086 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9087 for literal assignments in genPackBits (thanks to Frieder for
9093 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9095 Fixed bug #748310 (pointer to function type mishandled when the
9096 function name is omitted). Also fixed a SIGSEGV when a function
9097 attribute (reentrant, etc) is used on a non-function or on a
9098 function but misplaced before the parameter list.
9100 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9102 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9103 * support/Util/SDCCerr.h,
9104 * support/Util/SDCCerr.c: Added func attr misuse error msg

9125 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9127 Made the constant following the "interrupt" keyword optional. If
9128 omitted, the function will not automatically be given an entry
9129 in the interrupt vector table (similar to #pragma NOIV, but
9130 less syntacticly kludgy). The interrupt number is also now
9131 range checked. Also fixed a bug in the high order bit example
9138 * support/Util/SDCCerr.c
9139 * support/Util/SDCCerr.h
9142 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9145 * src/SDCCicode.c (operandOperation): rewritten some ops
9146 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9147 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9149 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9150 be re-activated by defining REDUCE_LITERALS)
9151 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9152 unsigned, but are signed by default
9153 * src/SDCCval.c (constVal): rearranged
9154 * src/SDCCval.c (valMod): preliminary fix
9155 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9198 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9199 * src/SDCCval.c (valDiv, valMod): fixed signdness
9200 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9201 signedness of modulo, left and right shift

9607 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9608 the regression tests I'm not brave enough to enable 245.b, 245.c
9609 * doc/sdccman.lyx: added latex preamble for hyperref package.
9610 Using pdflatex this will give you a hyperlinked pdf file with
9611 bookmarks. (prepend '%' before /usepackage if this breaks something)

9649 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9651 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9652 it can be defined with CFLAGS when running configure
9653 * src/SDCCmain.c: fixed compiling + linking with object files
9655 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9658 added --disable-pic16-port
9659 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9660 * src/SDCCmain.c: linkOptions is changed to set *,
9661 added if/endif conditional macros to remove options help
9662 messages from optionsTable when a port is not configured, added
9663 support for the PIc16 port in the ports table, when executing
9664 the compiler with no port specified on command line, a default
9665 port is selected with the new macro DEFAULT_PORT which is
9666 defined in port.h, in setDefaultOptions() linkOptions is removed
9667 from initialization assignment, since now it is a set,
9668 parseCmdLine uses setParseWithComma for linkOptions, in
9669 linkEdit() linkOptions are accessed with new function indexSet()
9670 which returns the i'th item of a set variable. See SDCCset.c, in
9671 linkEdit() when calling buildCmdLine(), added linkOptions as
9672 last argument. Now users can pass arguments to gplink via the
9673 -Wl option, main() uses pic16glue() to glue up pic16 programs

9685 * src/pic16/glue.c: commented out some error producing lines
9686 * src/pic16/main.c: __config directives are commented out to stop
9687 gpasm complaining and test the linkage with gplink, _linkCmd and
9688 _asmCmd changed to be more gplink and gpasm friendly
9689 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9690 produced an error when parsed, peep rule 12 is added to utilize
9691 movff, but it is commented out since the pCode does not support
9692 yet a command with 2 address arguments
9694 2003-05-18 <johan AT balder>
9696 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9723 2003-05-11 Borut Razem <borut.razem AT siol.net>
9725 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9726 the path of bin directory, so that PATH is the only env. variable, which has to be set
9727 in case of standard installation.
9728 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10800 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10803 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10804 area BSEG. Also moves, if possible, the DATA area down into the internal
10805 ram so more space is available.
10807 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10810 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10811 not bytes. Function summary() which creates a memory usage summary
10812 file with extension .mem. Reports of overlaping stack and small stack
10813 size. If the space for the stack is less than 16 bytes aslink trows a
10816 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10817 the 8051. Option 'y' for memory summary output file.
10819 Changes to sdcc (All the changes are marked with 'JCF'):
10821 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10823 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10824 overlaying area for it (uses RegBankUsed[4]).
10826 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10827 bank zero as used by default. By default aslink locates the stack
10828 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10829 the creation of the .mem file. Delegates the allocation of data area
10830 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10831 the begining of the stack area to aslink.
10833 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10834 glue() in SDCCglue.c creates an area for it.
10836 2002-09-03 Borut Razem <borut.razem AT siol.net>
10837 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10838 sdcc/src/pic/glue.c:
10839 introduced atexit() handler for teporay files removal in case of
10840 errors, assertions, ...
10842 2002-08-29 Borut Razem <borut.razem AT siol.net>
10843 * sdcc/support/cpp2/auto-host_vc_in.h:
10844 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10845 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10846 Maybe there is a similar problem with BORLANDC? It should be checked!
10848 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10849 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10850 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10851 was not executed, and the compiler (cl) launched a warning:
10852 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10854 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10855 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10857 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10858 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10860 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10861 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10862 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10863 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10864 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10865 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10866 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10867 - added Release configuration in VS projects
10868 - review of compiler an linker options
10869 - VC .exe files are generated in bin_vc directory, not to interfere
10870 with binaries generated from other projects (cygwin, mingw, bcc ...)
10872 * sdcc/src/yacc.dsp: added
10874 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10875 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10876 and insert the version number definitions from .version
10878 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10880 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10881 added - genarate auto-host.h using auto-host_vc_in.h as template
10884 removed from CVS, generated automatically
10886 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10887 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10889 2002-08-11 Borut Razem <borut.razem AT siol.net>
10890 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10892 2002-08-10 Borut Razem <borut.razem AT siol.net>
10893 * src/SDCCmain.c (main):
10894 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10895 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10896 The consequence was that some temporary files were not removed.
10899 unification of code in functions tempfilename() and tempfile():
10900 function tempnam() is defined in Visual Studio 6.0 and .NET
10902 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10904 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10905 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10906 - removed compiler command line option /WX: Treats all warnings as errors
10907 - update a list of source files, included into the project
10909 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10910 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10911 changed project type to Generic Project so that can be correcly converted to VS.NET project
10913 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10915 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10917 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10919 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10920 added return 0 statements after assert() to make compiler happy
10922 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10923 added newline in the def file to keep MSC compiler satisfied
10925 * sdcc/src/z80/gen.c:
10926 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10927 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10928 - solved MSC error in function aopDump()
10930 * sdcc_vc.h: define PREFIX as "\\sdcc"
10932 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10933 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10970 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10972 2002-03-28 Johan Knol <johan AT balder>
10974 * src/SDCCval.c: fixed bug #532436
10976 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10978 Added "char *Processor" field to the port structure.
10981 Added -p option. Allows port dependent processor to be specified.
10984 Initialized the new field char *Processor field to NULL in all ports
10987 Compiler generated registers for interrupt context saving
10988 were not getting allocated.
10990 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

11105 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11107 * sdcc/src/SDCCloop.c:
11108 Previous fix was not good. basic blocks that have "break" or "return" are
11109 not really partof a loop , but live ranges used in these blocks should
11110 be live thru the entire loop, so set partOfLoop but don't add them to
11113 2002-02-21 <johan AT FRIJA>
11115 * src/SDCCcse.c: fixed bug #514308
11117 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
