1105 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1107 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1108 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1110 One basic decision: e.g. src/clean.mk includes further files. In order
1111 to make this work there are two solutions:
1112 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1113 run configure on them. This way they can use
1114 'include $(srcdir)/port-clean.mk'
1115 - always include clean.mk by the Makefile at the same level. To avoid
1116 that `make clean` tries to include and build Makefile.dep the
1117 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1118 implemented, because now even `make uninstall` doesn't create
1119 Makefile.in. clean.mk could be eliminated by pasting it in
1122 * debugger/mcs51/Makefile.in: build own objects from library sources
1123 (SLIB, SDCC) in current directory
1125 * configure, configure.in: renamed --disable-device-lib-build in
1126 --disable-device-lib; added --enable-doc, the required tools are
1127 searched by configure; added result message; the toolchain for the
1128 belonging ports are now only built, if the port is enabled.
1130 * support/regression/*: all output is written in directory gen, because
1131 the fwk and ports directories don't livet in the build tree using vpath
1133 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1134 --disable-device-lib, added --enable-doc, added section VPATH
1136 * sim/ucsim/configure.in,
1137 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1138 z80 are enabled by default
1140 2006-04-24 Raphael Neider <rneider AT web.de>
1142 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1143 to config word, "pic14_"-prefixed some extern functions
1144 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1145 config word has been found
1146 * src/pic/device.h: added prototypes
1147 * src/pic/pcode.c: added "pic14_"-prefix where needed
1148 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1150 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1152 (pic14emitRegularMap): ignore config words,
1153 (pic14createInterruptVect): moved generating __config directives away

1164 fixes #1469504 and #1474602,
1165 (pCodeRegOptimizeRegUsage): fixed typo in comment

1388 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1390 * src/mcs51/gen.c (genCall): fixed bug 1457608
1392 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1394 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1397 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1399 * src/SDCCpeeph.c (operandsLiteral): new, added,

1411 implemented patch 1120823 Thanks to Willy De la Court (normal
1412 interrupts need an interrupt number now if they are made critical),
1413 and enabled nesting of critical functions though not for gbz80
1414 (genCritical, genEndCritical): added functions
1415 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1416 * src/z80/mappings.i: added "ei" to all mappings

1421 submitted by the Debian SDCC maintainer Aurelien Jarno:
1422 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1423 archive with gcc 4.1 on mips and wrote the patch"
1425 2006-03-16 Raphael Neider <rneider AT web.de>
1427 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1428 the left operand is shorter than the result (c* = lit-c* + int),
1430 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1433 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1435 * src/.version: increased version number to 2.5.5
1436 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1437 linking is done manually in pic16 port's _linkEdit,
1438 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1439 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1440 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1441 allocate asmop as AOP_ACC,
1442 (aopForRemat): added parameter 'bool result' in function declaration,
1443 (pic16_aopGet): return AOP_ACC when accessing WREG,
1444 (pic16_popGetTempReg): minor modification,
1445 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1446 'pic16_allocWithIdx',
1447 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1448 calling function in absolute addresses,
1449 (genAssign): take into account AOP_ACC asmop,
1450 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1453 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1455 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1456 call to allocReg, not by manually allocating a new one,
1457 (pic16_assignRegisters): now before going through the register
1458 allocating functions mark all registers as free. This eliminates some
1459 side effects resulting from peephole parser done earlier in the backbone
1461 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1463 * src/SDCCicode.c (geniCodeLogic),

1482 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1483 (aopForSym, aopOp): increment asmop.allocated if reused,
1484 (freeAsmop): decrement asmop.allocated and check for zero instead of
1486 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1487 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1488 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1511 2006-03-06 Borut Razem <borut.razem AT siol.net>
1513 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1514 made the linker quiet
1516 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1518 * src/pic16/gen.c (genPcall): fixed bug #1443644
1519 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1520 which dumps before the function entry point a data byte which represents
1521 the number of the local variables used by the specified function, added
1522 'xinst' for initial support for Extended Instruction Support,
1523 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1524 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1525 port->fun_prefix anymore (may change later),
1526 (genFunction, genEndFunction): do not store/restore local registers for
1527 _main (this should take care the --main-return command line option in
1529 (genOr): removed some legacy pic-port instructions,
1530 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1531 performing operations with SFR's causes data to be written more than
1532 once to each SFR. Perhaps SFRs should be handled in special cases...
1533 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1535 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1536 into account for stack starting position,
1537 (struct OPTIONS pic16_optionsTable): added command line argument
1538 --extended or -y for Extended Instruction Support,
1539 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1540 (deassignLRs): *** perhaps the most important change, old 'for' code
1541 (commented out for reference), didn't account for some registers which
1542 were left marked 'not free' after a pointer operation. The change
1543 reduces register usage a lot in some cases
1545 2006-03-04 Borut Razem <borut.razem AT siol.net>
1547 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3857 * src/z80/ralloc.c (z80_assignRegisters),
3859 * src/SDCCopt.c (eBBlockFromiCode, replaceRegEqv, killDeadCode),
3860 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
3862 * src/SDCCdflow.c (computeDataFlow),
3864 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
3866 * src/SDCCcflow.c (*),
3868 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3869 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3870 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3871 immedDom() returning wrong block; probably fixes bug #1160833)
3873 2005-03-20 Borut Razem <borut.razem AT siol.net>
3875 * support/scripts/inc2h.pl: WIN32 port
3877 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3879 * device/lib/makefile.in: added abs.c and labs.c
3881 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3883 * device/include/stdint.h: added
3884 * device/lib/abs.c: added
3885 * device/lib/labs.c: added
3886 * device/include/stdlib.h: added abs() and labs() prototypes
3887 * device/lib/libsdcc.lib: added abs and labs
3888 * device/include/float.h,
3889 * device/lib/_fsmul.c,
3890 * device/lib/printf_fast.c,
3891 * device/lib/printf_tiny.c: updated comments
3893 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3895 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3898 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3900 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3901 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3903 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3905 * device/lib/printf_large.c: removed inline assembly for portability and
3906 readability. Use printf_fast if speed or size are more important.
3907 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3908 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3910 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3912 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3913 prevent compiler warning
3915 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3917 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3918 moved to level 0 and declared as static. Also they are explicit
3919 placed in access bank. This was necessery because some times they
3920 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3921 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3922 optimizations. Currently only compare to unsigned char is implemented,
3923 * src/pic16/gen.c: added fReturnIdx array,
3924 * (struct resolvedIfx) is moved to gen.h and made public,
3925 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3926 * (aopForSym): added an optimization to directly store in stack of
3927 the operand of a SEND iCode,
3928 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3929 but as registers instead (AOP_REG) using the fReturnIdx array,
3930 * (pic16_freeAsmop): remove the freed register from the
3931 _G.sregsAlloc field,
3932 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3933 a compare of 'WREG',
3934 * (pic16_popGetTempRegCond): changed function prototype, now
3935 function takes also a bitVector argument v which holds the current
3936 set of registers that are allocated for stack access by aopForSym,
3937 registers allocated in aopForSym for accessing stack symbols are not
3938 any more part of the functions usedRegs field,
3939 * (genCall): some times aopOp is called for a stack variable to be
3940 send, aopForSym might perform the push, if this is true make sure
3941 that genCall doesn't push the variable twice by testing _G.resDirect,
3942 * (genFunction): changed testing for unspecified interrupt number
3943 from 256 to INTNO_UNSPEC,
3944 * modified selection scheme of frame pointer generation. Previously
3945 if function did use local registers a frame pointer was generated,
3946 now a frame pointer is generated only if function has arguments
3947 (that need PLUSW2 register access), or has stack arguments, or the
3948 compiler is not instructed to omit the frame pointer,
3949 * (genEndFunction): before restoring local registers that were saved
3950 in the function preamble, also restore the registers that *might*
3951 have been allocated for stack access,
3952 * (genRet): removed some old comments,
3953 * (genCmp, the active (RN's) version): added a call to the
3954 pic16_genCmp_special function to perform the compare with a more
3955 robust and optimized way,
3956 * (genInline): a feature has been added in inline code generation,
3957 which allows a wildcard variable substitution when writing inline
3958 assembly. Code is incomplete and experimental therefore undocumented,
3959 * (genCast): changed order of aopOp for result and right to allow
3960 aopForSym to directly load the result if possible,
3961 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3962 perform an optimized compare on some selected special occasions,
3963 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3964 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3965 generate an IVT any more,
3966 * src/pic16/main.c (pic16_optionsTable): added command line option
3968 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3969 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3971 * src/pic16/NOTES: Raphael Neider added in list of active developers
3972 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3973 jumptable_end to prevent bug #,
3974 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3975 inCond and outCond fields,
3976 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3977 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3978 turn off register spilling,
3979 * (packRegsForOneUse): synced with other ports' versions although it
3980 is not used currently,
3981 * (pic16_packRegisters): added an optimization while reading
3982 structure bitfields, some registers may be saved (malloc code is
3983 decreased by 80 bytes)
3985 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3987 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3988 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3989 this can be optimized more?
3991 2005-03-10 Raphael Neider <rneider AT web.de>
3993 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3994 genNearPointerGet): (hopefully) fixed access to bitfields via
3995 pointers (p->bitN = x; and x = p->bitN; failed)
3997 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4040 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4041 to keep the correct label reference count when adding/removing references
4042 to labels. A peephole file using this is appended to patch #1144962.

4184 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4185 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4186 this might fix SIGSEGVs on MinGW...
4187 * src/SDCCopt.c (killDeadCode): restored original behaviour
4188 (volatile operands might get thrown away though)
4190 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4274 * (genUminus): rewritten to for efficiency
4275 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4276 used uninitialized in some cases)

4278 copy the third byte from the int -- now assumes 0x80 (data memory)
4279 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4280 operands (genAddLit expects the iCode's operands to swapped as
4281 well), fixed leftover bytes (crashed for short left operands)

4668 functions, ctype functions and macros and some functions of the
4669 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4670 be extensively tested in the future. Standard disclaimer here.

4684 * (genCmp): experimental code for new genCmp which uses PIC18's
4685 special compare&skip instructions. Initial tests fail some times
4686 with variables grater than 1 byte in size, so new code is disabled,
4687 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4689 * (genCast): began a fix to optimize the casting of a bit to another
4690 bit, now assigning a bitfield to another bitfield will fail, sorry,

7713 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7715 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7716 loaded with the linker search paths (-L arguments) and the libraries
7717 to be linked with the current source (-l arguments). Changes
7718 currently will affect only the pic16 port.
7719 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7720 include path the port specific paths and port specific libraries,
7721 * gplink command now contains the $3 argument,
7722 * src/pic16/device.h,
7723 * src/pic16/device.c,: structure PIC_device is made public and
7724 renamed to PIC16_device, the same for variable Pics which is renamed

7739 Documenting changes from previous commits.
7740 * configure.in (version 1.56),
7741 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7742 when generating output files to configure the pic16 library,
7743 but now I've commented it out, since gputils aren't installed in the
7744 SF compile farm, so library won't compile
7746 * device/lib/Makefile.in (version 1.56): initially I've added in
7747 target 'all' the prerequestive 'model-pic16' so it compiled the
7748 pic16 library, but now I've commented it out for the same reasons
7750 * added targets 'model-pic16' and 'objects-pic16' to compile the
7752 * added target 'port-specific-objects-pic16' to handle the
7753 generated libraries and copy them into the build/ directory
7754 * added target 'clean-intermediate-pic16' to clean intermediate
7755 files into pic16 directory
7756 * in target 'installdirs' added line to create directory pic16 in
7757 the installation path

7760 added lines to copy all header files to installation path,
7761 * in target 'installdirs' added line create directory for pic16
7762 headers in the installation path

7777 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7778 option so that it actually works. Made it specific to the z80, since
7779 the gbz80 doesn't have these kinds of I/O ports.
7781 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7783 * device/include/z180.h,

7807 via literal number. The symbol is placed in the corresponding
7808 position of the data ram
7809 * (pic16_dump_section): relocatable and absolute uninitialized
7810 data are now emitted in sorted order to reduce section naming,
7811 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7812 weren't marked as being in the access bank,
7814 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7816 Added portion of GNU PIC Library under the directory
7817 device/include/pic16 and device/lib/pic16. These files
7818 contain the declarations of SFRs for the PIC18Fxx2 devices.
7819 The directory is initialized via configure from toplevel.
7821 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7823 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7830 2004-01-12 Borut Razem <borut.razem AT siol.net>
7832 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
7833 doc/sdccman.lyx: upper case pragmas are deprecated
7835 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

7848 * doc/sdccman.lyx: Moved and added some sections, small changes
7849 all over. Telling LaTeX to be less strict with word spacing
7850 to better keep the right margin. Changed some notes about
7851 maintainance of the ports in section 3.2.1 - is it OK like this?
7853 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7855 SDCC source changes:
7856 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7891 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7893 * src/pic16/peeph.def: all peepholes with movff are commented out,
7894 because there is a problem in the pcode peep optimizer,
7895 * src/pic16/ralloc.c: the register allocator can now reuse local

7988 include information about variables allocated to the overlay
7991 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7993 * as/mcs51/lkmain.c: Help about -Y option

8005 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8007 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8008 (default behaviour).
8010 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8012 A python script to validate compiler diagnostic messages. It can be
8013 used to verify that sdcc complains about bad c source code and
8014 gives a good location of the error.
8015 * support/valdiag/Makefile,
8016 * support/valdiag/valdiag.py,
8017 * support/valdiag/tests/*

8033 around the header file.
8034 Bug reported from Jesus Calvino-Fraga
8036 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8038 * sdcc.spec: updated
8039 * device/include/Makefile.in: don't install CVS directories
8040 * device/lib/Makefile.in: added removal of CVS directories after install
8041 * doc/Makefile: fixed install, added local_icons
8042 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8043 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8044 * src/ds390/gen.c (genRightShift): fixed bug #870788
8045 * src/SDCCast.c (decorateType): fixed bug #870781
8047 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8049 PIC16 port related changes:
8050 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8051 added variable stackPos,
8053 * gen.c: genCall, assignResultValue: added support for
8054 pushing/retrieving function parameters to/from stack,
8055 genFunction,genEndFunction: setup stack frame for the
8057 genAddrOf: will be changed according to bug 863624
8059 * added files genutils.c and genutils.h which contain gen*
8060 debugged and optimised functions extracted from gen.c
8062 * glue.c: added variable 'externs' which holds extern symbols,
8063 pic16emitRegularMap: is modified to properly handle relocatable
8064 symbols under the new scheme,
8065 pic16createInterruptVect: is modified
8066 pic16printPublics: is modified to emit 'global' assembler directives,
8067 added pic16_printExterns to print extern symbols,
8068 pic16glue: initializes stack/frame pointer in the beginning of
8069 the assembly output. Temporary hack, will be corrected later,
8070 because gplink yet does not support stack and SDCC does not
8071 yet support a type of crt0.o object to create the final binary.
8073 * Removed many lines that contain 8051 legacy code.
8074 * The code is finally placed under a 'code' directive.
8075 * Added port specific options.
8077 * _process_pragma: simplified since now we do not need *special*
8078 include file to define SFR registers. But a separate header
8079 will be needed. This will be developed later.
8080 * _pic16_parseOptions: added, parses port specific options:
8081 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8082 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8083 --preplace-udata-with=
8085 * _pic16_setDefaultOptions: modified to initialize section names,
8086 but hack is temporarly out of order since it needs improvement.
8087 * _pic16_genAssemblerPreamble: configuration words are emitted by
8088 their address instead of their name. This part is incomplete and
8089 supports only the 18Fxx2 devices. Other devices will emit an error
8090 during assembly since they do not contain the same set of config
8092 * _pic16_genIVT: is modified,
8094 * pcode.c: added definitions for some hardware registers that are needed
8096 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8097 All PCI entries are updated. Now LFSR is supported.
8098 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8099 * added pic16_newpCodeOpLit2 to support instructions with
8100 two literal arguments
8101 * pic16_pCode2str: corrected code that emits assembler instructions
8102 with two literal operands and those that have an access bit modifier
8103 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8104 this fixes a bug which caused some labels to be lost, when an
8105 assembler directive was added, i.e. banksel,
8106 * pic16_FixRegisterBanking: improved logic that causes the insertion
8108 * InlineFunction: functions that are called once, are not any more
8109 inlined. This can be a port option in the future,
8111 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8113 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8114 hold the corresponding uninitialized symbols,
8115 * pic16_allocProcessorRegister: registers have explicit marked the
8117 * pic16_allocInternalRegister: registers are explicit marked as
8119 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8120 processing list, so bit registers were lost,
8123 * ralloc.h: added field 'accessBank' and original symbol operand
8124 in register definition,
8125 * removed the field isMapped from register definition,
8127 ** Several functions have been removed from various sources:
8128 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8129 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8130 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8131 pic16_assignRelocatableRegisters
8133 ** others have been introduced:
8134 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8135 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8137 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8139 * support/scripts/inc2h.pl: changed definition of BIT_AT
8140 to emit 'sbit at' instead of 'bit at'. This was a request.
8142 PIC16 port related preliminary changes:
8143 * gen.c: prefixed function popRegFromString with
8144 pic16_ and all references to it corrected
8145 * pcode.c: all pic16_pc_* hardware registers prefixed
8146 with underscore (_),
8147 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8148 * ralloc.c: newReg(): when register is REG_SFR then
8149 set address to rIdx,
8150 pic16_allocProcessorRegister(): marks register wasUsed=0
8151 pic16_writeUsedRegs(): added a call to assign processor
8152 registers via pic16_assignFixedRegisters
8154 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8156 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8157 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8158 variables in unused register banks. Also the SSEG is placed
8159 wherever there is enough space for it, and IDATA can be anywhere
8160 in internal RAM. For now compile using -Wl-Y[stack_size].
8161 The mem file is different for this option as well, since it
8162 makes no sense of talking about DSEG lenght.
8164 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8166 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8167 in certain cases, e.g. when ROM assignment, patch provided
8168 from Albert den Haan.
8170 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8313 * src/mcs51/peephole.def,
8314 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9193 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9194 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9195 type for bits was changed. It resulted in bit variables becoming

9213 A few small changes that speed up the peephole optimizer.
9217 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9219 Try to make the peephole optimizer smarter by maintaining
9220 an association between the assembly source code and the
9221 iCodes that originated them. Put this information to use
9222 with a new peephole rule condition "notVolatile" so that
9223 the rules can be aggressive yet still safe.
9228 * src/mcs51/peeph.def
9230 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9234 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9235 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9236 if the left or right operand symbols have the accuse flag set.
9238 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9240 Changed the type of the result of the ! (NOT) operator to char;
9241 previously it returned the same type as the source. This allows
9242 us to eliminate all the genFloatNot functions (all of its target
9243 implementations were very buggy) since !float can use the same
9246 * src/SDCCicode.c (ast2iCode): ! returns char

9255 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9256 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9257 during interrupts. Ensure WSAVE is located at a shared bank address.
9258 2. Fixed page selection in some places
9259 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9260 the registers name strings.
9261 4. Fixed "signed / unsigned compare" compiler warnings.
9262 5. The PIC port manages its own allocation of the general purpose
9263 registers, but makes no attempt to reuse them. As a result when
9264 compiling it soon runs out of general purpose registers. Some
9265 additional code was added to the files pcode.c and device.c to walk
9266 through the function call tree and rename the registers so that they
9276 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9277 genPlus() & genMinus() when the result is the same as left or right

9283 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9285 Made bitfield a distinct type from bit so that bitfields
9286 convert as per ANSI C and bits retain their traditional
9287 boolean style behaviour. Implemented bitfield support in
9295 * src/ds390/gen.c: bit v bitfield split
9296 * src/z80/gen.c: New support for bitfields
9297 * support/regression/tests/bitfields.c: reenabled z80,
9300 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9302 Rules 246.x, 247.x relate to bitfields, the others speed up
9303 access to xdata mapped I/O devices.
9305 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9307 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9309 Cleaned up genPackBits and genUnpackBits and added two helper

9311 for literal assignments in genPackBits (thanks to Frieder for
9317 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9319 Fixed bug #748310 (pointer to function type mishandled when the
9320 function name is omitted). Also fixed a SIGSEGV when a function
9321 attribute (reentrant, etc) is used on a non-function or on a
9322 function but misplaced before the parameter list.

9351 Made the constant following the "interrupt" keyword optional. If
9352 omitted, the function will not automatically be given an entry
9353 in the interrupt vector table (similar to #pragma NOIV, but
9354 less syntacticly kludgy). The interrupt number is also now
9355 range checked. Also fixed a bug in the high order bit example
9362 * support/Util/SDCCerr.c
9363 * support/Util/SDCCerr.h
9366 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9375 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9376 unsigned, but are signed by default
9377 * src/SDCCval.c (constVal): rearranged
9378 * src/SDCCval.c (valMod): preliminary fix
9379 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9422 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9423 * src/SDCCval.c (valDiv, valMod): fixed signdness
9424 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9425 signedness of modulo, left and right shift
9426 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

9888 the compiler with no port specified on command line, a default
9889 port is selected with the new macro DEFAULT_PORT which is
9890 defined in port.h, in setDefaultOptions() linkOptions is removed
9891 from initialization assignment, since now it is a set,
9892 parseCmdLine uses setParseWithComma for linkOptions, in
9893 linkEdit() linkOptions are accessed with new function indexSet()

10968 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10969 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10975 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10976 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10978 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10979 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10981 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10983 * in /sdcc/as/mcs51/ changed these files in order to create an
10984 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10985 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10986 following files to include the previous two files: aslink.dsp,
10987 Makefile.aslink, Makefile.bcc, and Makefile.in.
10989 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10990 .adb instead of .cdb
10992 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10994 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10995 value from option --iram-size.
10997 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10999 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11002 2002-09-18 <wiml AT hhhh.org>
11004 * SDCClrange.h: exposed setFromRange() and setToRange()
11005 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11006 packRegsForAccUse() (bug 542397)
11007 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11008 multiple times and emitting the fetch operations more than once
11009 added aopGetUsesAcc() function to allow binary operators to
11010 fetch their operands in the correct order; made genMinus() emit
11011 compact code for X = LITERAL - Y
11013 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11014 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11015 sprintf() in line 1267.
11017 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11018 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11021 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11022 Changes to aslink (All the changes are marked with 'JCF'):
11024 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11027 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11028 area BSEG. Also moves, if possible, the DATA area down into the internal
11029 ram so more space is available.
11031 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11034 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11035 not bytes. Function summary() which creates a memory usage summary
11036 file with extension .mem. Reports of overlaping stack and small stack
11037 size. If the space for the stack is less than 16 bytes aslink trows a
11040 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11041 the 8051. Option 'y' for memory summary output file.
11043 Changes to sdcc (All the changes are marked with 'JCF'):
11045 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11047 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11048 overlaying area for it (uses RegBankUsed[4]).
11050 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11051 bank zero as used by default. By default aslink locates the stack
11052 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11053 the creation of the .mem file. Delegates the allocation of data area
11054 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11055 the begining of the stack area to aslink.
11057 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11058 glue() in SDCCglue.c creates an area for it.
11060 2002-09-03 Borut Razem <borut.razem AT siol.net>
11061 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11062 sdcc/src/pic/glue.c:
11063 introduced atexit() handler for teporay files removal in case of
11064 errors, assertions, ...
11066 2002-08-29 Borut Razem <borut.razem AT siol.net>
11067 * sdcc/support/cpp2/auto-host_vc_in.h:
11068 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11069 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11070 Maybe there is a similar problem with BORLANDC? It should be checked!
11072 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11073 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11074 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11075 was not executed, and the compiler (cl) launched a warning:
11076 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11078 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11079 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11081 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11082 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11084 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11085 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11086 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11087 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11088 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11089 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11090 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11091 - added Release configuration in VS projects
11092 - review of compiler an linker options
11093 - VC .exe files are generated in bin_vc directory, not to interfere
11094 with binaries generated from other projects (cygwin, mingw, bcc ...)
11096 * sdcc/src/yacc.dsp: added
11098 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11099 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11100 and insert the version number definitions from .version
11102 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11104 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11105 added - genarate auto-host.h using auto-host_vc_in.h as template
11108 removed from CVS, generated automatically
11110 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11111 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11113 2002-08-11 Borut Razem <borut.razem AT siol.net>
11114 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11116 2002-08-10 Borut Razem <borut.razem AT siol.net>
11117 * src/SDCCmain.c (main):
11118 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11119 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11120 The consequence was that some temporary files were not removed.
11123 unification of code in functions tempfilename() and tempfile():
11124 function tempnam() is defined in Visual Studio 6.0 and .NET
11126 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11128 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11129 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11130 - removed compiler command line option /WX: Treats all warnings as errors
11131 - update a list of source files, included into the project
11133 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11134 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11135 changed project type to Generic Project so that can be correcly converted to VS.NET project
11137 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11139 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11141 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11143 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11144 added return 0 statements after assert() to make compiler happy
11146 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11147 added newline in the def file to keep MSC compiler satisfied
11149 * sdcc/src/z80/gen.c:
11150 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11151 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11152 - solved MSC error in function aopDump()
11154 * sdcc_vc.h: define PREFIX as "\\sdcc"
11156 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11157 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11159 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11160 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11161 - Rewrote the register banking algorithm.
11162 - Added pCode live-range analysis to registers (for now, only non-used and
11163 singly-used registers optimized away)
11165 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11167 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
