1082 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1084 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1085 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1087 One basic decision: e.g. src/clean.mk includes further files. In order
1088 to make this work there are two solutions:
1089 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1090 run configure on them. This way they can use
1091 'include $(srcdir)/port-clean.mk'
1092 - always include clean.mk by the Makefile at the same level. To avoid
1093 that `make clean` tries to include and build Makefile.dep the
1094 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1095 implemented, because now even `make uninstall` doesn't create
1096 Makefile.in. clean.mk could be eliminated by pasting it in
1099 * debugger/mcs51/Makefile.in: build own objects from library sources
1100 (SLIB, SDCC) in current directory
1102 * configure, configure.in: renamed --disable-device-lib-build in
1103 --disable-device-lib; added --enable-doc, the required tools are
1104 searched by configure; added result message; the toolchain for the
1105 belonging ports are now only built, if the port is enabled.
1107 * support/regression/*: all output is written in directory gen, because
1108 the fwk and ports directories don't livet in the build tree using vpath
1110 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1111 --disable-device-lib, added --enable-doc, added section VPATH
1113 * sim/ucsim/configure.in,
1114 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1115 z80 are enabled by default
1117 2006-04-24 Raphael Neider <rneider AT web.de>
1119 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1120 to config word, "pic14_"-prefixed some extern functions
1121 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1122 config word has been found
1123 * src/pic/device.h: added prototypes
1124 * src/pic/pcode.c: added "pic14_"-prefix where needed
1125 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1127 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1141 fixes #1469504 and #1474602,
1142 (pCodeRegOptimizeRegUsage): fixed typo in comment

1359 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1361 * src/SDCCpeeph.c (initPeepHole): implemented RFE 1460196, when both

1365 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1367 * src/mcs51/gen.c (genCall): fixed bug 1457608
1369 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1371 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1374 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1376 * src/SDCCpeeph.c (operandsLiteral): new, added,
1377 (callFuncByName): inserted operandsLiteral

1387 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1388 implemented patch 1120823 Thanks to Willy De la Court (normal
1389 interrupts need an interrupt number now if they are made critical),
1390 and enabled nesting of critical functions though not for gbz80
1391 (genCritical, genEndCritical): added functions
1392 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1393 * src/z80/mappings.i: added "ei" to all mappings
1395 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1397 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1398 submitted by the Debian SDCC maintainer Aurelien Jarno:
1399 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1400 archive with gcc 4.1 on mips and wrote the patch"
1402 2006-03-16 Raphael Neider <rneider AT web.de>
1404 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1405 the left operand is shorter than the result (c* = lit-c* + int),
1407 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1410 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1412 * src/.version: increased version number to 2.5.5
1413 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1414 linking is done manually in pic16 port's _linkEdit,
1415 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1416 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1417 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1418 allocate asmop as AOP_ACC,
1419 (aopForRemat): added parameter 'bool result' in function declaration,
1420 (pic16_aopGet): return AOP_ACC when accessing WREG,
1421 (pic16_popGetTempReg): minor modification,
1422 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1423 'pic16_allocWithIdx',
1424 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1425 calling function in absolute addresses,
1426 (genAssign): take into account AOP_ACC asmop,
1427 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1428 * src/pic16/pcoderegs.c: some debug functions and lines added,
1429 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1430 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1432 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1433 call to allocReg, not by manually allocating a new one,
1434 (pic16_assignRegisters): now before going through the register
1435 allocating functions mark all registers as free. This eliminates some
1436 side effects resulting from peephole parser done earlier in the backbone
1438 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1440 * src/SDCCicode.c (geniCodeLogic),

1458 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
1459 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1460 (aopForSym, aopOp): increment asmop.allocated if reused,
1461 (freeAsmop): decrement asmop.allocated and check for zero instead of
1463 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1464 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1465 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1488 2006-03-06 Borut Razem <borut.razem AT siol.net>
1490 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1491 made the linker quiet
1493 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1495 * src/pic16/gen.c (genPcall): fixed bug #1443644
1496 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1497 which dumps before the function entry point a data byte which represents
1498 the number of the local variables used by the specified function, added
1499 'xinst' for initial support for Extended Instruction Support,
1500 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1501 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1502 port->fun_prefix anymore (may change later),
1503 (genFunction, genEndFunction): do not store/restore local registers for
1504 _main (this should take care the --main-return command line option in
1506 (genOr): removed some legacy pic-port instructions,
1507 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1508 performing operations with SFR's causes data to be written more than
1509 once to each SFR. Perhaps SFRs should be handled in special cases...
1510 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1512 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1513 into account for stack starting position,
1514 (struct OPTIONS pic16_optionsTable): added command line argument
1515 --extended or -y for Extended Instruction Support,
1516 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1517 (deassignLRs): *** perhaps the most important change, old 'for' code
1518 (commented out for reference), didn't account for some registers which
1519 were left marked 'not free' after a pointer operation. The change
1520 reduces register usage a lot in some cases
1522 2006-03-04 Borut Razem <borut.razem AT siol.net>
1524 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3858 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3860 * device/include/stdint.h: added
3861 * device/lib/abs.c: added
3862 * device/lib/labs.c: added
3863 * device/include/stdlib.h: added abs() and labs() prototypes
3864 * device/lib/libsdcc.lib: added abs and labs
3865 * device/include/float.h,
3866 * device/lib/_fsmul.c,
3867 * device/lib/printf_fast.c,
3868 * device/lib/printf_tiny.c: updated comments
3870 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3872 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3875 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3877 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3878 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3880 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3882 * device/lib/printf_large.c: removed inline assembly for portability and
3883 readability. Use printf_fast if speed or size are more important.
3884 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3885 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3887 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3889 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3890 prevent compiler warning
3892 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3894 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3895 moved to level 0 and declared as static. Also they are explicit
3896 placed in access bank. This was necessery because some times they
3897 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3898 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3899 optimizations. Currently only compare to unsigned char is implemented,
3900 * src/pic16/gen.c: added fReturnIdx array,
3901 * (struct resolvedIfx) is moved to gen.h and made public,
3902 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3903 * (aopForSym): added an optimization to directly store in stack of
3904 the operand of a SEND iCode,
3905 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3906 but as registers instead (AOP_REG) using the fReturnIdx array,
3907 * (pic16_freeAsmop): remove the freed register from the
3908 _G.sregsAlloc field,
3909 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3910 a compare of 'WREG',
3911 * (pic16_popGetTempRegCond): changed function prototype, now
3912 function takes also a bitVector argument v which holds the current
3913 set of registers that are allocated for stack access by aopForSym,
3914 registers allocated in aopForSym for accessing stack symbols are not
3915 any more part of the functions usedRegs field,
3916 * (genCall): some times aopOp is called for a stack variable to be
3917 send, aopForSym might perform the push, if this is true make sure
3918 that genCall doesn't push the variable twice by testing _G.resDirect,
3919 * (genFunction): changed testing for unspecified interrupt number
3920 from 256 to INTNO_UNSPEC,
3921 * modified selection scheme of frame pointer generation. Previously
3922 if function did use local registers a frame pointer was generated,
3923 now a frame pointer is generated only if function has arguments
3924 (that need PLUSW2 register access), or has stack arguments, or the
3925 compiler is not instructed to omit the frame pointer,
3926 * (genEndFunction): before restoring local registers that were saved
3927 in the function preamble, also restore the registers that *might*
3928 have been allocated for stack access,
3929 * (genRet): removed some old comments,
3930 * (genCmp, the active (RN's) version): added a call to the
3931 pic16_genCmp_special function to perform the compare with a more
3932 robust and optimized way,
3933 * (genInline): a feature has been added in inline code generation,
3934 which allows a wildcard variable substitution when writing inline
3935 assembly. Code is incomplete and experimental therefore undocumented,
3936 * (genCast): changed order of aopOp for result and right to allow
3937 aopForSym to directly load the result if possible,
3938 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3939 perform an optimized compare on some selected special occasions,
3940 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3941 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3942 generate an IVT any more,
3943 * src/pic16/main.c (pic16_optionsTable): added command line option
3945 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3946 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3948 * src/pic16/NOTES: Raphael Neider added in list of active developers
3949 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3950 jumptable_end to prevent bug #,
3951 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3952 inCond and outCond fields,
3953 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3954 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3955 turn off register spilling,
3956 * (packRegsForOneUse): synced with other ports' versions although it
3957 is not used currently,
3958 * (pic16_packRegisters): added an optimization while reading
3959 structure bitfields, some registers may be saved (malloc code is
3960 decreased by 80 bytes)
3962 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3964 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3965 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3966 this can be optimized more?
3968 2005-03-10 Raphael Neider <rneider AT web.de>
3970 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3971 genNearPointerGet): (hopefully) fixed access to bitfields via
3972 pointers (p->bitN = x; and x = p->bitN; failed)
3974 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4015 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4017 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4018 to keep the correct label reference count when adding/removing references
4019 to labels. A peephole file using this is appended to patch #1144962.

4162 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4163 this might fix SIGSEGVs on MinGW...

4607 generated for switch statements. For now you need to set the
4608 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4609 Now 4 algorithms for mcs51 jumptable generation are used:
4610 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4642 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4644 * added libc directory. The current version of LibC contains string
4645 functions, ctype functions and macros and some functions of the
4646 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4647 be extensively tested in the future. Standard disclaimer here.
4648 Library is not automatically build yet. But one can build it by

4660 * (pic16_storeForReturn): optimized return of 0,
4661 * (genCmp): experimental code for new genCmp which uses PIC18's
4662 special compare&skip instructions. Initial tests fail some times
4663 with variables grater than 1 byte in size, so new code is disabled,
4664 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4666 * (genCast): began a fix to optimize the casting of a bit to another
4667 bit, now assigning a bitfield to another bitfield will fail, sorry,

4681 registers when it shouldn't,
4682 * src/pic16/ralloc.c (allocReg): add preliminary support for
4683 supporting a limited set of temporary registers,
4685 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4709 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4711 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7690 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7692 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7693 loaded with the linker search paths (-L arguments) and the libraries
7694 to be linked with the current source (-l arguments). Changes
7695 currently will affect only the pic16 port.
7696 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7697 include path the port specific paths and port specific libraries,
7698 * gplink command now contains the $3 argument,
7699 * src/pic16/device.h,
7700 * src/pic16/device.c,: structure PIC_device is made public and

7716 Documenting changes from previous commits.
7717 * configure.in (version 1.56),
7718 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7719 when generating output files to configure the pic16 library,
7720 but now I've commented it out, since gputils aren't installed in the
7721 SF compile farm, so library won't compile
7723 * device/lib/Makefile.in (version 1.56): initially I've added in
7724 target 'all' the prerequestive 'model-pic16' so it compiled the
7725 pic16 library, but now I've commented it out for the same reasons
7727 * added targets 'model-pic16' and 'objects-pic16' to compile the
7729 * added target 'port-specific-objects-pic16' to handle the
7730 generated libraries and copy them into the build/ directory
7731 * added target 'clean-intermediate-pic16' to clean intermediate
7732 files into pic16 directory
7733 * in target 'installdirs' added line to create directory pic16 in
7734 the installation path

7737 added lines to copy all header files to installation path,
7738 * in target 'installdirs' added line create directory for pic16
7739 headers in the installation path

7754 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7755 option so that it actually works. Made it specific to the z80, since
7756 the gbz80 doesn't have these kinds of I/O ports.
7758 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7760 * device/include/z180.h,

7784 via literal number. The symbol is placed in the corresponding
7785 position of the data ram
7786 * (pic16_dump_section): relocatable and absolute uninitialized
7787 data are now emitted in sorted order to reduce section naming,
7788 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7789 weren't marked as being in the access bank,
7791 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7793 Added portion of GNU PIC Library under the directory
7794 device/include/pic16 and device/lib/pic16. These files
7795 contain the declarations of SFRs for the PIC18Fxx2 devices.
7796 The directory is initialized via configure from toplevel.
7798 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7826 all over. Telling LaTeX to be less strict with word spacing
7827 to better keep the right margin. Changed some notes about
7828 maintainance of the ports in section 3.2.1 - is it OK like this?
7830 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7984 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7985 (default behaviour).
7987 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7989 A python script to validate compiler diagnostic messages. It can be

8024 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8026 PIC16 port related changes:
8027 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8028 added variable stackPos,
8030 * gen.c: genCall, assignResultValue: added support for
8031 pushing/retrieving function parameters to/from stack,
8032 genFunction,genEndFunction: setup stack frame for the
8034 genAddrOf: will be changed according to bug 863624
8036 * added files genutils.c and genutils.h which contain gen*
8037 debugged and optimised functions extracted from gen.c
8039 * glue.c: added variable 'externs' which holds extern symbols,
8040 pic16emitRegularMap: is modified to properly handle relocatable
8041 symbols under the new scheme,
8042 pic16createInterruptVect: is modified
8043 pic16printPublics: is modified to emit 'global' assembler directives,
8044 added pic16_printExterns to print extern symbols,
8045 pic16glue: initializes stack/frame pointer in the beginning of
8046 the assembly output. Temporary hack, will be corrected later,
8047 because gplink yet does not support stack and SDCC does not
8048 yet support a type of crt0.o object to create the final binary.
8050 * Removed many lines that contain 8051 legacy code.
8051 * The code is finally placed under a 'code' directive.
8052 * Added port specific options.
8054 * _process_pragma: simplified since now we do not need *special*
8055 include file to define SFR registers. But a separate header
8056 will be needed. This will be developed later.
8057 * _pic16_parseOptions: added, parses port specific options:
8058 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8059 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8060 --preplace-udata-with=
8062 * _pic16_setDefaultOptions: modified to initialize section names,
8063 but hack is temporarly out of order since it needs improvement.
8064 * _pic16_genAssemblerPreamble: configuration words are emitted by
8065 their address instead of their name. This part is incomplete and
8066 supports only the 18Fxx2 devices. Other devices will emit an error
8067 during assembly since they do not contain the same set of config
8069 * _pic16_genIVT: is modified,
8071 * pcode.c: added definitions for some hardware registers that are needed
8073 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8074 All PCI entries are updated. Now LFSR is supported.
8075 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8076 * added pic16_newpCodeOpLit2 to support instructions with
8077 two literal arguments
8078 * pic16_pCode2str: corrected code that emits assembler instructions
8079 with two literal operands and those that have an access bit modifier
8080 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8081 this fixes a bug which caused some labels to be lost, when an
8082 assembler directive was added, i.e. banksel,
8083 * pic16_FixRegisterBanking: improved logic that causes the insertion
8085 * InlineFunction: functions that are called once, are not any more
8086 inlined. This can be a port option in the future,
8088 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8090 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8091 hold the corresponding uninitialized symbols,
8092 * pic16_allocProcessorRegister: registers have explicit marked the
8094 * pic16_allocInternalRegister: registers are explicit marked as
8096 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8097 processing list, so bit registers were lost,
8100 * ralloc.h: added field 'accessBank' and original symbol operand
8101 in register definition,
8102 * removed the field isMapped from register definition,
8104 ** Several functions have been removed from various sources:
8105 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8106 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8107 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8108 pic16_assignRelocatableRegisters
8110 ** others have been introduced:
8111 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8112 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8114 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8116 * support/scripts/inc2h.pl: changed definition of BIT_AT
8117 to emit 'sbit at' instead of 'bit at'. This was a request.
8119 PIC16 port related preliminary changes:
8120 * gen.c: prefixed function popRegFromString with
8121 pic16_ and all references to it corrected
8122 * pcode.c: all pic16_pc_* hardware registers prefixed
8123 with underscore (_),
8124 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8125 * ralloc.c: newReg(): when register is REG_SFR then
8126 set address to rIdx,
8127 pic16_allocProcessorRegister(): marks register wasUsed=0
8128 pic16_writeUsedRegs(): added a call to assign processor
8129 registers via pic16_assignFixedRegisters
8131 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8133 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8134 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8135 variables in unused register banks. Also the SSEG is placed
8136 wherever there is enough space for it, and IDATA can be anywhere
8137 in internal RAM. For now compile using -Wl-Y[stack_size].
8138 The mem file is different for this option as well, since it
8139 makes no sense of talking about DSEG lenght.
8141 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8143 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8144 in certain cases, e.g. when ROM assignment, patch provided
8145 from Albert den Haan.
8147 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8290 * src/mcs51/peephole.def,
8291 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8292 (allows non-interrupt and interrupt code to safely compete for a resource

9032 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9033 support for standard C idiom of memory mapped variables; for
9034 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9035 to xdata int at 0x1234 tempvar = 1.
9036 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9037 provided by Akiya ISHIDA

9053 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9055 Fixed bug #621531 (const & volatile confusion in the type chain).
9056 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9057 refer to the const or volatile state of the pointer itself.

9122 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9123 pcoderegs.h, ralloc.c, ralloc.h
9124 * main.c: added top header and GPL license notice

9148 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9149 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9150 fetching of the pointer
9151 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9152 copied from genNearPointerSet()
9153 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9154 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9155 If they pop r0/r1 they must be called in the opposite order than aopOp().
9156 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9157 (resp. --stack-auto), prepared for --xstack

9166 these ports have their own __sdcc_external_start()
9168 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9170 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9171 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9172 type for bits was changed. It resulted in bit variables becoming
9173 global, which is not permitted in PIC 14 assembly output.
9175 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9177 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9188 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9190 A few small changes that speed up the peephole optimizer.
9194 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9196 Try to make the peephole optimizer smarter by maintaining
9197 an association between the assembly source code and the
9198 iCodes that originated them. Put this information to use
9199 with a new peephole rule condition "notVolatile" so that
9200 the rules can be aggressive yet still safe.
9205 * src/mcs51/peeph.def
9207 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9211 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9212 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9213 if the left or right operand symbols have the accuse flag set.
9215 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9217 Changed the type of the result of the ! (NOT) operator to char;
9218 previously it returned the same type as the source. This allows
9219 us to eliminate all the genFloatNot functions (all of its target
9220 implementations were very buggy) since !float can use the same
9223 * src/SDCCicode.c (ast2iCode): ! returns char
9224 * src/mcs51/gen.c (genNot, genNotFloat),
9225 * src/ds390/gen.c (genNot, genNotFloat),
9226 * src/z80/gen.c (genNot, genNotFloat),
9227 * src/pic/gen.c (genNot, genNotFloat),
9228 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9230 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9232 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9233 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9234 during interrupts. Ensure WSAVE is located at a shared bank address.
9235 2. Fixed page selection in some places
9236 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9237 the registers name strings.
9238 4. Fixed "signed / unsigned compare" compiler warnings.
9239 5. The PIC port manages its own allocation of the general purpose
9240 registers, but makes no attempt to reuse them. As a result when
9241 compiling it soon runs out of general purpose registers. Some
9242 additional code was added to the files pcode.c and device.c to walk
9243 through the function call tree and rename the registers so that they
9253 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9254 genPlus() & genMinus() when the result is the same as left or right
9256 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9260 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9262 Made bitfield a distinct type from bit so that bitfields
9263 convert as per ANSI C and bits retain their traditional
9264 boolean style behaviour. Implemented bitfield support in
9272 * src/ds390/gen.c: bit v bitfield split
9273 * src/z80/gen.c: New support for bitfields
9274 * support/regression/tests/bitfields.c: reenabled z80,
9277 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9279 Rules 246.x, 247.x relate to bitfields, the others speed up
9280 access to xdata mapped I/O devices.
9282 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9284 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9286 Cleaned up genPackBits and genUnpackBits and added two helper
9287 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9288 for literal assignments in genPackBits (thanks to Frieder for
9294 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9296 Fixed bug #748310 (pointer to function type mishandled when the
9297 function name is omitted). Also fixed a SIGSEGV when a function
9298 attribute (reentrant, etc) is used on a non-function or on a
9299 function but misplaced before the parameter list.
9301 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9303 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9304 * support/Util/SDCCerr.h,
9305 * support/Util/SDCCerr.c: Added func attr misuse error msg
9307 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9309 Fixed bug #787649 by anonymous
9310 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9311 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9313 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9315 Fixed numerous bitfield problems.
9317 * src/SDCC.y: More bitfield related error checking
9319 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
9320 * support/Util/SDCCerr.h,
9321 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs

9323 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
9324 * support/regression/tests/bitfields.c: tests added
9326 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9328 Made the constant following the "interrupt" keyword optional. If
9329 omitted, the function will not automatically be given an entry
9330 in the interrupt vector table (similar to #pragma NOIV, but
9331 less syntacticly kludgy). The interrupt number is also now
9332 range checked. Also fixed a bug in the high order bit example
9339 * support/Util/SDCCerr.c
9340 * support/Util/SDCCerr.h
9343 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9345 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9346 * src/SDCCicode.c (operandOperation): rewritten some ops
9347 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9348 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9350 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9351 be re-activated by defining REDUCE_LITERALS)

9862 added if/endif conditional macros to remove options help
9863 messages from optionsTable when a port is not configured, added
9864 support for the PIc16 port in the ports table, when executing
9865 the compiler with no port specified on command line, a default
9866 port is selected with the new macro DEFAULT_PORT which is
9867 defined in port.h, in setDefaultOptions() linkOptions is removed
9868 from initialization assignment, since now it is a set,
9869 parseCmdLine uses setParseWithComma for linkOptions, in
9870 linkEdit() linkOptions are accessed with new function indexSet()
9871 which returns the i'th item of a set variable. See SDCCset.c, in
9872 linkEdit() when calling buildCmdLine(), added linkOptions as
9873 last argument. Now users can pass arguments to gplink via the
9874 -Wl option, main() uses pic16glue() to glue up pic16 programs

9888 gpasm complaining and test the linkage with gplink, _linkCmd and
9889 _asmCmd changed to be more gplink and gpasm friendly
9890 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9891 produced an error when parsed, peep rule 12 is added to utilize
9892 movff, but it is commented out since the pCode does not support
9893 yet a command with 2 address arguments
9895 2003-05-18 <johan AT balder>
9897 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10956 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10958 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10960 * in /sdcc/as/mcs51/ changed these files in order to create an
10961 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10962 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10963 following files to include the previous two files: aslink.dsp,
10964 Makefile.aslink, Makefile.bcc, and Makefile.in.
10966 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10967 .adb instead of .cdb
10969 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10971 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10972 value from option --iram-size.
10974 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10976 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10979 2002-09-18 <wiml AT hhhh.org>
10981 * SDCClrange.h: exposed setFromRange() and setToRange()
10982 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10983 packRegsForAccUse() (bug 542397)
10984 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10985 multiple times and emitting the fetch operations more than once
10986 added aopGetUsesAcc() function to allow binary operators to
10987 fetch their operands in the correct order; made genMinus() emit
10988 compact code for X = LITERAL - Y
10990 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10991 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10992 sprintf() in line 1267.
10994 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10995 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10998 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10999 Changes to aslink (All the changes are marked with 'JCF'):
11001 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11004 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11005 area BSEG. Also moves, if possible, the DATA area down into the internal
11006 ram so more space is available.
11008 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11011 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11012 not bytes. Function summary() which creates a memory usage summary
11013 file with extension .mem. Reports of overlaping stack and small stack
11014 size. If the space for the stack is less than 16 bytes aslink trows a
11017 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11018 the 8051. Option 'y' for memory summary output file.
11020 Changes to sdcc (All the changes are marked with 'JCF'):
11022 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11024 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11025 overlaying area for it (uses RegBankUsed[4]).
11027 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11028 bank zero as used by default. By default aslink locates the stack
11029 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11030 the creation of the .mem file. Delegates the allocation of data area
11031 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11032 the begining of the stack area to aslink.
11034 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11035 glue() in SDCCglue.c creates an area for it.
11037 2002-09-03 Borut Razem <borut.razem AT siol.net>
11038 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11039 sdcc/src/pic/glue.c:
11040 introduced atexit() handler for teporay files removal in case of
11041 errors, assertions, ...
11043 2002-08-29 Borut Razem <borut.razem AT siol.net>
11044 * sdcc/support/cpp2/auto-host_vc_in.h:
11045 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11046 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11047 Maybe there is a similar problem with BORLANDC? It should be checked!
11049 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11050 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11051 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11052 was not executed, and the compiler (cl) launched a warning:
11053 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11055 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11056 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11058 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11059 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11061 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11062 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11063 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11064 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11065 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11066 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11067 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11068 - added Release configuration in VS projects
11069 - review of compiler an linker options
11070 - VC .exe files are generated in bin_vc directory, not to interfere
11071 with binaries generated from other projects (cygwin, mingw, bcc ...)
11073 * sdcc/src/yacc.dsp: added
11075 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11076 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11077 and insert the version number definitions from .version
11079 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11081 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11082 added - genarate auto-host.h using auto-host_vc_in.h as template
11085 removed from CVS, generated automatically
11087 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11088 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11090 2002-08-11 Borut Razem <borut.razem AT siol.net>
11091 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11093 2002-08-10 Borut Razem <borut.razem AT siol.net>
11094 * src/SDCCmain.c (main):
11095 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11096 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11097 The consequence was that some temporary files were not removed.
11100 unification of code in functions tempfilename() and tempfile():
11101 function tempnam() is defined in Visual Studio 6.0 and .NET
11103 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11105 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11106 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11107 - removed compiler command line option /WX: Treats all warnings as errors
11108 - update a list of source files, included into the project
11110 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11111 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11112 changed project type to Generic Project so that can be correcly converted to VS.NET project
11114 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11116 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11118 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11120 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11121 added return 0 statements after assert() to make compiler happy
11123 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11124 added newline in the def file to keep MSC compiler satisfied
11126 * sdcc/src/z80/gen.c:
11127 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11128 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11129 - solved MSC error in function aopDump()
11131 * sdcc_vc.h: define PREFIX as "\\sdcc"
11133 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11134 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11137 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11138 - Rewrote the register banking algorithm.
11139 - Added pCode live-range analysis to registers (for now, only non-used and
11140 singly-used registers optimized away)
11142 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11144 * 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.
11146 2002-05-10 Scott Dattalo <scott AT dattalo.com>
