1110 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1112 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1113 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1115 One basic decision: e.g. src/clean.mk includes further files. In order
1116 to make this work there are two solutions:
1117 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1118 run configure on them. This way they can use
1119 'include $(srcdir)/port-clean.mk'
1120 - always include clean.mk by the Makefile at the same level. To avoid
1121 that `make clean` tries to include and build Makefile.dep the
1122 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1123 implemented, because now even `make uninstall` doesn't create
1124 Makefile.in. clean.mk could be eliminated by pasting it in
1127 * debugger/mcs51/Makefile.in: build own objects from library sources
1128 (SLIB, SDCC) in current directory
1130 * configure, configure.in: renamed --disable-device-lib-build in
1131 --disable-device-lib; added --enable-doc, the required tools are
1132 searched by configure; added result message; the toolchain for the
1133 belonging ports are now only built, if the port is enabled.
1135 * support/regression/*: all output is written in directory gen, because
1136 the fwk and ports directories don't livet in the build tree using vpath
1138 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1139 --disable-device-lib, added --enable-doc, added section VPATH
1141 * sim/ucsim/configure.in,
1142 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1143 z80 are enabled by default
1145 2006-04-24 Raphael Neider <rneider AT web.de>
1147 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1148 to config word, "pic14_"-prefixed some extern functions
1149 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1150 config word has been found
1151 * src/pic/device.h: added prototypes
1152 * src/pic/pcode.c: added "pic14_"-prefix where needed
1153 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1155 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1158 (pic14createInterruptVect): moved generating __config directives away

1169 fixes #1469504 and #1474602,
1170 (pCodeRegOptimizeRegUsage): fixed typo in comment

1174 * device/examples/main8051.c: deleted - it was removed from CVS

1393 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1395 * src/mcs51/gen.c (genCall): fixed bug 1457608
1397 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1399 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1402 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1404 * src/SDCCpeeph.c (operandsLiteral): new, added,

1416 implemented patch 1120823 Thanks to Willy De la Court (normal
1417 interrupts need an interrupt number now if they are made critical),
1418 and enabled nesting of critical functions though not for gbz80
1419 (genCritical, genEndCritical): added functions
1420 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1421 * src/z80/mappings.i: added "ei" to all mappings
1423 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1425 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1426 submitted by the Debian SDCC maintainer Aurelien Jarno:
1427 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1428 archive with gcc 4.1 on mips and wrote the patch"
1430 2006-03-16 Raphael Neider <rneider AT web.de>
1432 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1433 the left operand is shorter than the result (c* = lit-c* + int),
1435 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1438 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1440 * src/.version: increased version number to 2.5.5
1441 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1442 linking is done manually in pic16 port's _linkEdit,
1443 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1444 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1445 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1446 allocate asmop as AOP_ACC,
1447 (aopForRemat): added parameter 'bool result' in function declaration,
1448 (pic16_aopGet): return AOP_ACC when accessing WREG,
1449 (pic16_popGetTempReg): minor modification,
1450 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1451 'pic16_allocWithIdx',
1452 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1453 calling function in absolute addresses,
1454 (genAssign): take into account AOP_ACC asmop,
1455 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1456 * src/pic16/pcoderegs.c: some debug functions and lines added,

1458 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1460 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1461 call to allocReg, not by manually allocating a new one,
1462 (pic16_assignRegisters): now before going through the register
1463 allocating functions mark all registers as free. This eliminates some
1464 side effects resulting from peephole parser done earlier in the backbone
1466 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1468 * src/SDCCicode.c (geniCodeLogic),

1487 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1488 (aopForSym, aopOp): increment asmop.allocated if reused,
1489 (freeAsmop): decrement asmop.allocated and check for zero instead of
1491 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1492 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1493 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1516 2006-03-06 Borut Razem <borut.razem AT siol.net>
1518 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1519 made the linker quiet
1521 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1523 * src/pic16/gen.c (genPcall): fixed bug #1443644
1524 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1525 which dumps before the function entry point a data byte which represents
1526 the number of the local variables used by the specified function, added
1527 'xinst' for initial support for Extended Instruction Support,
1528 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1529 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1530 port->fun_prefix anymore (may change later),
1531 (genFunction, genEndFunction): do not store/restore local registers for
1532 _main (this should take care the --main-return command line option in
1534 (genOr): removed some legacy pic-port instructions,
1535 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1536 performing operations with SFR's causes data to be written more than
1537 once to each SFR. Perhaps SFRs should be handled in special cases...
1538 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1540 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1541 into account for stack starting position,
1542 (struct OPTIONS pic16_optionsTable): added command line argument
1543 --extended or -y for Extended Instruction Support,
1544 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1545 (deassignLRs): *** perhaps the most important change, old 'for' code
1546 (commented out for reference), didn't account for some registers which
1547 were left marked 'not free' after a pointer operation. The change
1548 reduces register usage a lot in some cases
1550 2006-03-04 Borut Razem <borut.razem AT siol.net>
1552 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3874 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3875 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3876 immedDom() returning wrong block; probably fixes bug #1160833)
3878 2005-03-20 Borut Razem <borut.razem AT siol.net>
3880 * support/scripts/inc2h.pl: WIN32 port
3882 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3884 * device/lib/makefile.in: added abs.c and labs.c
3886 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3888 * device/include/stdint.h: added
3889 * device/lib/abs.c: added
3890 * device/lib/labs.c: added
3891 * device/include/stdlib.h: added abs() and labs() prototypes
3892 * device/lib/libsdcc.lib: added abs and labs
3893 * device/include/float.h,
3894 * device/lib/_fsmul.c,
3895 * device/lib/printf_fast.c,
3896 * device/lib/printf_tiny.c: updated comments
3898 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3900 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3903 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3905 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3906 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3908 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3910 * device/lib/printf_large.c: removed inline assembly for portability and
3911 readability. Use printf_fast if speed or size are more important.
3912 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3913 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3915 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3917 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3918 prevent compiler warning
3920 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3922 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3923 moved to level 0 and declared as static. Also they are explicit
3924 placed in access bank. This was necessery because some times they
3925 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3926 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3927 optimizations. Currently only compare to unsigned char is implemented,
3928 * src/pic16/gen.c: added fReturnIdx array,
3929 * (struct resolvedIfx) is moved to gen.h and made public,
3930 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3931 * (aopForSym): added an optimization to directly store in stack of
3932 the operand of a SEND iCode,
3933 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3934 but as registers instead (AOP_REG) using the fReturnIdx array,
3935 * (pic16_freeAsmop): remove the freed register from the
3936 _G.sregsAlloc field,
3937 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3938 a compare of 'WREG',
3939 * (pic16_popGetTempRegCond): changed function prototype, now
3940 function takes also a bitVector argument v which holds the current
3941 set of registers that are allocated for stack access by aopForSym,
3942 registers allocated in aopForSym for accessing stack symbols are not
3943 any more part of the functions usedRegs field,
3944 * (genCall): some times aopOp is called for a stack variable to be
3945 send, aopForSym might perform the push, if this is true make sure
3946 that genCall doesn't push the variable twice by testing _G.resDirect,
3947 * (genFunction): changed testing for unspecified interrupt number
3948 from 256 to INTNO_UNSPEC,
3949 * modified selection scheme of frame pointer generation. Previously
3950 if function did use local registers a frame pointer was generated,
3951 now a frame pointer is generated only if function has arguments
3952 (that need PLUSW2 register access), or has stack arguments, or the
3953 compiler is not instructed to omit the frame pointer,
3954 * (genEndFunction): before restoring local registers that were saved
3955 in the function preamble, also restore the registers that *might*
3956 have been allocated for stack access,
3957 * (genRet): removed some old comments,
3958 * (genCmp, the active (RN's) version): added a call to the
3959 pic16_genCmp_special function to perform the compare with a more
3960 robust and optimized way,
3961 * (genInline): a feature has been added in inline code generation,
3962 which allows a wildcard variable substitution when writing inline
3963 assembly. Code is incomplete and experimental therefore undocumented,
3964 * (genCast): changed order of aopOp for result and right to allow
3965 aopForSym to directly load the result if possible,
3966 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3967 perform an optimized compare on some selected special occasions,
3968 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3969 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3970 generate an IVT any more,
3971 * src/pic16/main.c (pic16_optionsTable): added command line option
3973 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3974 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3976 * src/pic16/NOTES: Raphael Neider added in list of active developers
3977 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3978 jumptable_end to prevent bug #,
3979 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3980 inCond and outCond fields,
3981 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3982 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3983 turn off register spilling,
3984 * (packRegsForOneUse): synced with other ports' versions although it
3985 is not used currently,
3986 * (pic16_packRegisters): added an optimization while reading
3987 structure bitfields, some registers may be saved (malloc code is
3988 decreased by 80 bytes)
3990 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3992 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3993 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3994 this can be optimized more?
3996 2005-03-10 Raphael Neider <rneider AT web.de>
3998 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3999 genNearPointerGet): (hopefully) fixed access to bitfields via
4000 pointers (p->bitN = x; and x = p->bitN; failed)
4002 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4043 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4045 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4046 to keep the correct label reference count when adding/removing references
4047 to labels. A peephole file using this is appended to patch #1144962.

4189 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4190 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4191 this might fix SIGSEGVs on MinGW...

4280 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4281 used uninitialized in some cases)

4283 copy the third byte from the int -- now assumes 0x80 (data memory)
4284 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4285 operands (genAddLit expects the iCode's operands to swapped as
4286 well), fixed leftover bytes (crashed for short left operands)

4672 * added libc directory. The current version of LibC contains string
4673 functions, ctype functions and macros and some functions of the
4674 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4675 be extensively tested in the future. Standard disclaimer here.
4676 Library is not automatically build yet. But one can build it by

4688 * (pic16_storeForReturn): optimized return of 0,
4689 * (genCmp): experimental code for new genCmp which uses PIC18's
4690 special compare&skip instructions. Initial tests fail some times
4691 with variables grater than 1 byte in size, so new code is disabled,
4692 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4694 * (genCast): began a fix to optimize the casting of a bit to another
4695 bit, now assigning a bitfield to another bitfield will fail, sorry,

4704 and 1 for banking instruction,
4705 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4706 caused stop processing pCodes after a inline assembly block,

4709 registers when it shouldn't,
4710 * src/pic16/ralloc.c (allocReg): add preliminary support for
4711 supporting a limited set of temporary registers,
4713 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4716 genDataPointerSet): ensure assignments always copy in MSB to LSB
4718 (loadRegFromAop): recognize CLRH optimization,
4719 (genFunction): optimize RECEIVE iCodes in reentrant functions
4721 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4723 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7718 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7720 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7721 loaded with the linker search paths (-L arguments) and the libraries
7722 to be linked with the current source (-l arguments). Changes
7723 currently will affect only the pic16 port.
7724 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7725 include path the port specific paths and port specific libraries,
7726 * gplink command now contains the $3 argument,
7727 * src/pic16/device.h,
7728 * src/pic16/device.c,: structure PIC_device is made public and
7729 renamed to PIC16_device, the same for variable Pics which is renamed

7744 Documenting changes from previous commits.
7745 * configure.in (version 1.56),
7746 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7747 when generating output files to configure the pic16 library,
7748 but now I've commented it out, since gputils aren't installed in the
7749 SF compile farm, so library won't compile
7751 * device/lib/Makefile.in (version 1.56): initially I've added in
7752 target 'all' the prerequestive 'model-pic16' so it compiled the
7753 pic16 library, but now I've commented it out for the same reasons
7755 * added targets 'model-pic16' and 'objects-pic16' to compile the
7757 * added target 'port-specific-objects-pic16' to handle the
7758 generated libraries and copy them into the build/ directory
7759 * added target 'clean-intermediate-pic16' to clean intermediate
7760 files into pic16 directory
7761 * in target 'installdirs' added line to create directory pic16 in
7762 the installation path
7764 * device/include/Makefile.in (version 1.11): in target 'install'
7765 added lines to copy all header files to installation path,
7766 * in target 'installdirs' added line create directory for pic16
7767 headers in the installation path

7782 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7783 option so that it actually works. Made it specific to the z80, since
7784 the gbz80 doesn't have these kinds of I/O ports.
7786 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7788 * device/include/z180.h,

7812 via literal number. The symbol is placed in the corresponding
7813 position of the data ram
7814 * (pic16_dump_section): relocatable and absolute uninitialized
7815 data are now emitted in sorted order to reduce section naming,
7816 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7817 weren't marked as being in the access bank,
7819 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7821 Added portion of GNU PIC Library under the directory
7822 device/include/pic16 and device/lib/pic16. These files
7823 contain the declarations of SFRs for the PIC18Fxx2 devices.
7824 The directory is initialized via configure from toplevel.
7826 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7851 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7853 * doc/sdccman.lyx: Moved and added some sections, small changes
7854 all over. Telling LaTeX to be less strict with word spacing
7855 to better keep the right margin. Changed some notes about
7856 maintainance of the ports in section 3.2.1 - is it OK like this?
7858 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7860 SDCC source changes:
7861 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8010 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8012 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8013 (default behaviour).
8015 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8017 A python script to validate compiler diagnostic messages. It can be
8018 used to verify that sdcc complains about bad c source code and
8019 gives a good location of the error.
8020 * support/valdiag/Makefile,
8021 * support/valdiag/valdiag.py,
8022 * support/valdiag/tests/*

8037 * src/common.h: added ifndef/define/endif macros
8038 around the header file.
8039 Bug reported from Jesus Calvino-Fraga
8041 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8043 * sdcc.spec: updated
8044 * device/include/Makefile.in: don't install CVS directories
8045 * device/lib/Makefile.in: added removal of CVS directories after install
8046 * doc/Makefile: fixed install, added local_icons
8047 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8048 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8049 * src/ds390/gen.c (genRightShift): fixed bug #870788
8050 * src/SDCCast.c (decorateType): fixed bug #870781
8052 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8054 PIC16 port related changes:
8055 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8056 added variable stackPos,
8058 * gen.c: genCall, assignResultValue: added support for
8059 pushing/retrieving function parameters to/from stack,
8060 genFunction,genEndFunction: setup stack frame for the
8062 genAddrOf: will be changed according to bug 863624
8064 * added files genutils.c and genutils.h which contain gen*
8065 debugged and optimised functions extracted from gen.c
8067 * glue.c: added variable 'externs' which holds extern symbols,
8068 pic16emitRegularMap: is modified to properly handle relocatable
8069 symbols under the new scheme,
8070 pic16createInterruptVect: is modified
8071 pic16printPublics: is modified to emit 'global' assembler directives,
8072 added pic16_printExterns to print extern symbols,
8073 pic16glue: initializes stack/frame pointer in the beginning of
8074 the assembly output. Temporary hack, will be corrected later,
8075 because gplink yet does not support stack and SDCC does not
8076 yet support a type of crt0.o object to create the final binary.
8078 * Removed many lines that contain 8051 legacy code.
8079 * The code is finally placed under a 'code' directive.
8080 * Added port specific options.
8082 * _process_pragma: simplified since now we do not need *special*
8083 include file to define SFR registers. But a separate header
8084 will be needed. This will be developed later.
8085 * _pic16_parseOptions: added, parses port specific options:
8086 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8087 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8088 --preplace-udata-with=
8090 * _pic16_setDefaultOptions: modified to initialize section names,
8091 but hack is temporarly out of order since it needs improvement.
8092 * _pic16_genAssemblerPreamble: configuration words are emitted by
8093 their address instead of their name. This part is incomplete and
8094 supports only the 18Fxx2 devices. Other devices will emit an error
8095 during assembly since they do not contain the same set of config
8097 * _pic16_genIVT: is modified,
8099 * pcode.c: added definitions for some hardware registers that are needed
8101 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8102 All PCI entries are updated. Now LFSR is supported.
8103 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8104 * added pic16_newpCodeOpLit2 to support instructions with
8105 two literal arguments
8106 * pic16_pCode2str: corrected code that emits assembler instructions
8107 with two literal operands and those that have an access bit modifier
8108 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8109 this fixes a bug which caused some labels to be lost, when an
8110 assembler directive was added, i.e. banksel,
8111 * pic16_FixRegisterBanking: improved logic that causes the insertion
8113 * InlineFunction: functions that are called once, are not any more
8114 inlined. This can be a port option in the future,
8116 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8118 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8119 hold the corresponding uninitialized symbols,
8120 * pic16_allocProcessorRegister: registers have explicit marked the
8122 * pic16_allocInternalRegister: registers are explicit marked as
8124 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8125 processing list, so bit registers were lost,
8128 * ralloc.h: added field 'accessBank' and original symbol operand
8129 in register definition,
8130 * removed the field isMapped from register definition,
8132 ** Several functions have been removed from various sources:
8133 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8134 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8135 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8136 pic16_assignRelocatableRegisters
8138 ** others have been introduced:
8139 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8140 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8142 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8144 * support/scripts/inc2h.pl: changed definition of BIT_AT
8145 to emit 'sbit at' instead of 'bit at'. This was a request.
8147 PIC16 port related preliminary changes:
8148 * gen.c: prefixed function popRegFromString with
8149 pic16_ and all references to it corrected
8150 * pcode.c: all pic16_pc_* hardware registers prefixed
8151 with underscore (_),
8152 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8153 * ralloc.c: newReg(): when register is REG_SFR then
8154 set address to rIdx,
8155 pic16_allocProcessorRegister(): marks register wasUsed=0
8156 pic16_writeUsedRegs(): added a call to assign processor
8157 registers via pic16_assignFixedRegisters
8159 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8161 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8162 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8163 variables in unused register banks. Also the SSEG is placed
8164 wherever there is enough space for it, and IDATA can be anywhere
8165 in internal RAM. For now compile using -Wl-Y[stack_size].
8166 The mem file is different for this option as well, since it
8167 makes no sense of talking about DSEG lenght.
8169 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8171 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8172 in certain cases, e.g. when ROM assignment, patch provided
8173 from Albert den Haan.
8175 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8318 * src/mcs51/peephole.def,
8319 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8320 (allows non-interrupt and interrupt code to safely compete for a resource

9198 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9199 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9200 type for bits was changed. It resulted in bit variables becoming

9218 A few small changes that speed up the peephole optimizer.
9222 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9224 Try to make the peephole optimizer smarter by maintaining
9225 an association between the assembly source code and the
9226 iCodes that originated them. Put this information to use
9227 with a new peephole rule condition "notVolatile" so that
9228 the rules can be aggressive yet still safe.
9233 * src/mcs51/peeph.def
9235 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9239 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9240 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9241 if the left or right operand symbols have the accuse flag set.
9243 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9245 Changed the type of the result of the ! (NOT) operator to char;
9246 previously it returned the same type as the source. This allows
9247 us to eliminate all the genFloatNot functions (all of its target
9248 implementations were very buggy) since !float can use the same
9251 * src/SDCCicode.c (ast2iCode): ! returns char

9260 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9261 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9262 during interrupts. Ensure WSAVE is located at a shared bank address.
9263 2. Fixed page selection in some places
9264 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9265 the registers name strings.
9266 4. Fixed "signed / unsigned compare" compiler warnings.
9267 5. The PIC port manages its own allocation of the general purpose
9268 registers, but makes no attempt to reuse them. As a result when
9269 compiling it soon runs out of general purpose registers. Some
9270 additional code was added to the files pcode.c and device.c to walk
9271 through the function call tree and rename the registers so that they
9281 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9282 genPlus() & genMinus() when the result is the same as left or right

9288 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9290 Made bitfield a distinct type from bit so that bitfields
9291 convert as per ANSI C and bits retain their traditional
9292 boolean style behaviour. Implemented bitfield support in
9300 * src/ds390/gen.c: bit v bitfield split
9301 * src/z80/gen.c: New support for bitfields
9302 * support/regression/tests/bitfields.c: reenabled z80,
9305 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9307 Rules 246.x, 247.x relate to bitfields, the others speed up
9308 access to xdata mapped I/O devices.
9310 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9312 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9314 Cleaned up genPackBits and genUnpackBits and added two helper

9316 for literal assignments in genPackBits (thanks to Frieder for
9322 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9324 Fixed bug #748310 (pointer to function type mishandled when the
9325 function name is omitted). Also fixed a SIGSEGV when a function
9326 attribute (reentrant, etc) is used on a non-function or on a
9327 function but misplaced before the parameter list.

9354 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9356 Made the constant following the "interrupt" keyword optional. If
9357 omitted, the function will not automatically be given an entry
9358 in the interrupt vector table (similar to #pragma NOIV, but
9359 less syntacticly kludgy). The interrupt number is also now
9360 range checked. Also fixed a bug in the high order bit example
9367 * support/Util/SDCCerr.c
9368 * support/Util/SDCCerr.h

9893 the compiler with no port specified on command line, a default
9894 port is selected with the new macro DEFAULT_PORT which is
9895 defined in port.h, in setDefaultOptions() linkOptions is removed
9896 from initialization assignment, since now it is a set,
9897 parseCmdLine uses setParseWithComma for linkOptions, in
9898 linkEdit() linkOptions are accessed with new function indexSet()
9899 which returns the i'th item of a set variable. See SDCCset.c, in

10984 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10986 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10988 * in /sdcc/as/mcs51/ changed these files in order to create an
10989 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10990 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10991 following files to include the previous two files: aslink.dsp,
10992 Makefile.aslink, Makefile.bcc, and Makefile.in.
10994 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10995 .adb instead of .cdb
10997 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10999 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11000 value from option --iram-size.
11002 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11004 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11007 2002-09-18 <wiml AT hhhh.org>
11009 * SDCClrange.h: exposed setFromRange() and setToRange()
11010 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11011 packRegsForAccUse() (bug 542397)
11012 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11013 multiple times and emitting the fetch operations more than once
11014 added aopGetUsesAcc() function to allow binary operators to
11015 fetch their operands in the correct order; made genMinus() emit
11016 compact code for X = LITERAL - Y
11018 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11019 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11020 sprintf() in line 1267.
11022 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11023 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11026 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11027 Changes to aslink (All the changes are marked with 'JCF'):
11029 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11032 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11033 area BSEG. Also moves, if possible, the DATA area down into the internal
11034 ram so more space is available.
11036 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11039 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11040 not bytes. Function summary() which creates a memory usage summary
11041 file with extension .mem. Reports of overlaping stack and small stack
11042 size. If the space for the stack is less than 16 bytes aslink trows a
11045 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11046 the 8051. Option 'y' for memory summary output file.
11048 Changes to sdcc (All the changes are marked with 'JCF'):
11050 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11052 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11053 overlaying area for it (uses RegBankUsed[4]).
11055 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11056 bank zero as used by default. By default aslink locates the stack
11057 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11058 the creation of the .mem file. Delegates the allocation of data area
11059 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11060 the begining of the stack area to aslink.
11062 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11063 glue() in SDCCglue.c creates an area for it.
11065 2002-09-03 Borut Razem <borut.razem AT siol.net>
11066 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11067 sdcc/src/pic/glue.c:
11068 introduced atexit() handler for teporay files removal in case of
11069 errors, assertions, ...
11071 2002-08-29 Borut Razem <borut.razem AT siol.net>
11072 * sdcc/support/cpp2/auto-host_vc_in.h:
11073 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11074 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11075 Maybe there is a similar problem with BORLANDC? It should be checked!
11077 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11078 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11079 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11080 was not executed, and the compiler (cl) launched a warning:
11081 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11083 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11084 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11086 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11087 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11089 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11090 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11091 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11092 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11093 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11094 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11095 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11096 - added Release configuration in VS projects
11097 - review of compiler an linker options
11098 - VC .exe files are generated in bin_vc directory, not to interfere
11099 with binaries generated from other projects (cygwin, mingw, bcc ...)
11101 * sdcc/src/yacc.dsp: added
11103 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11104 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11105 and insert the version number definitions from .version
11107 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11109 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11110 added - genarate auto-host.h using auto-host_vc_in.h as template
11113 removed from CVS, generated automatically
11115 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11116 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11118 2002-08-11 Borut Razem <borut.razem AT siol.net>
11119 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11121 2002-08-10 Borut Razem <borut.razem AT siol.net>
11122 * src/SDCCmain.c (main):
11123 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11124 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11125 The consequence was that some temporary files were not removed.
11128 unification of code in functions tempfilename() and tempfile():
11129 function tempnam() is defined in Visual Studio 6.0 and .NET
11131 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11133 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11134 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11135 - removed compiler command line option /WX: Treats all warnings as errors
11136 - update a list of source files, included into the project
11138 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11139 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11140 changed project type to Generic Project so that can be correcly converted to VS.NET project
11142 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11144 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11146 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11148 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11149 added return 0 statements after assert() to make compiler happy
11151 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11152 added newline in the def file to keep MSC compiler satisfied
11154 * sdcc/src/z80/gen.c:
11155 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11156 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11157 - solved MSC error in function aopDump()
11159 * sdcc_vc.h: define PREFIX as "\\sdcc"
11161 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11162 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11164 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11165 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11166 - Rewrote the register banking algorithm.
11167 - Added pCode live-range analysis to registers (for now, only non-used and
