1086 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1088 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1089 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1091 One basic decision: e.g. src/clean.mk includes further files. In order
1092 to make this work there are two solutions:
1093 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1094 run configure on them. This way they can use
1095 'include $(srcdir)/port-clean.mk'
1096 - always include clean.mk by the Makefile at the same level. To avoid
1097 that `make clean` tries to include and build Makefile.dep the
1098 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1099 implemented, because now even `make uninstall` doesn't create
1100 Makefile.in. clean.mk could be eliminated by pasting it in
1103 * debugger/mcs51/Makefile.in: build own objects from library sources
1104 (SLIB, SDCC) in current directory
1106 * configure, configure.in: renamed --disable-device-lib-build in
1107 --disable-device-lib; added --enable-doc, the required tools are
1108 searched by configure; added result message; the toolchain for the
1109 belonging ports are now only built, if the port is enabled.
1111 * support/regression/*: all output is written in directory gen, because
1112 the fwk and ports directories don't livet in the build tree using vpath
1114 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1115 --disable-device-lib, added --enable-doc, added section VPATH
1117 * sim/ucsim/configure.in,
1118 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1119 z80 are enabled by default
1121 2006-04-24 Raphael Neider <rneider AT web.de>
1123 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1124 to config word, "pic14_"-prefixed some extern functions
1125 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1126 config word has been found
1127 * src/pic/device.h: added prototypes
1128 * src/pic/pcode.c: added "pic14_"-prefix where needed
1129 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1131 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1145 fixes #1469504 and #1474602,
1146 (pCodeRegOptimizeRegUsage): fixed typo in comment

1369 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1371 * src/mcs51/gen.c (genCall): fixed bug 1457608
1373 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1375 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1378 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1380 * src/SDCCpeeph.c (operandsLiteral): new, added,

1391 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1392 implemented patch 1120823 Thanks to Willy De la Court (normal
1393 interrupts need an interrupt number now if they are made critical),
1394 and enabled nesting of critical functions though not for gbz80
1395 (genCritical, genEndCritical): added functions
1396 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1397 * src/z80/mappings.i: added "ei" to all mappings
1399 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1401 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1402 submitted by the Debian SDCC maintainer Aurelien Jarno:
1403 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1404 archive with gcc 4.1 on mips and wrote the patch"
1406 2006-03-16 Raphael Neider <rneider AT web.de>
1408 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1409 the left operand is shorter than the result (c* = lit-c* + int),
1411 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1414 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1416 * src/.version: increased version number to 2.5.5
1417 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1418 linking is done manually in pic16 port's _linkEdit,
1419 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1420 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1421 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1422 allocate asmop as AOP_ACC,
1423 (aopForRemat): added parameter 'bool result' in function declaration,
1424 (pic16_aopGet): return AOP_ACC when accessing WREG,
1425 (pic16_popGetTempReg): minor modification,
1426 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1427 'pic16_allocWithIdx',
1428 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1429 calling function in absolute addresses,
1430 (genAssign): take into account AOP_ACC asmop,
1431 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1432 * src/pic16/pcoderegs.c: some debug functions and lines added,
1433 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1434 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1436 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1437 call to allocReg, not by manually allocating a new one,
1438 (pic16_assignRegisters): now before going through the register
1439 allocating functions mark all registers as free. This eliminates some
1440 side effects resulting from peephole parser done earlier in the backbone
1442 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1444 * src/SDCCicode.c (geniCodeLogic),

1462 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
1463 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1464 (aopForSym, aopOp): increment asmop.allocated if reused,
1465 (freeAsmop): decrement asmop.allocated and check for zero instead of
1467 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1468 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1469 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1492 2006-03-06 Borut Razem <borut.razem AT siol.net>
1494 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1495 made the linker quiet
1497 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1499 * src/pic16/gen.c (genPcall): fixed bug #1443644
1500 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1501 which dumps before the function entry point a data byte which represents
1502 the number of the local variables used by the specified function, added
1503 'xinst' for initial support for Extended Instruction Support,
1504 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1505 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1506 port->fun_prefix anymore (may change later),
1507 (genFunction, genEndFunction): do not store/restore local registers for
1508 _main (this should take care the --main-return command line option in
1510 (genOr): removed some legacy pic-port instructions,
1511 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1512 performing operations with SFR's causes data to be written more than
1513 once to each SFR. Perhaps SFRs should be handled in special cases...
1514 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1516 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1517 into account for stack starting position,
1518 (struct OPTIONS pic16_optionsTable): added command line argument
1519 --extended or -y for Extended Instruction Support,
1520 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1521 (deassignLRs): *** perhaps the most important change, old 'for' code
1522 (commented out for reference), didn't account for some registers which
1523 were left marked 'not free' after a pointer operation. The change
1524 reduces register usage a lot in some cases
1526 2006-03-04 Borut Razem <borut.razem AT siol.net>
1528 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3858 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3860 * device/lib/makefile.in: added abs.c and labs.c
3862 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3864 * device/include/stdint.h: added
3865 * device/lib/abs.c: added
3866 * device/lib/labs.c: added
3867 * device/include/stdlib.h: added abs() and labs() prototypes
3868 * device/lib/libsdcc.lib: added abs and labs
3869 * device/include/float.h,
3870 * device/lib/_fsmul.c,
3871 * device/lib/printf_fast.c,
3872 * device/lib/printf_tiny.c: updated comments
3874 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3876 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3879 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3881 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3882 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3884 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3886 * device/lib/printf_large.c: removed inline assembly for portability and
3887 readability. Use printf_fast if speed or size are more important.
3888 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3889 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3891 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3893 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3894 prevent compiler warning
3896 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3898 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3899 moved to level 0 and declared as static. Also they are explicit
3900 placed in access bank. This was necessery because some times they
3901 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3902 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3903 optimizations. Currently only compare to unsigned char is implemented,
3904 * src/pic16/gen.c: added fReturnIdx array,
3905 * (struct resolvedIfx) is moved to gen.h and made public,
3906 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3907 * (aopForSym): added an optimization to directly store in stack of
3908 the operand of a SEND iCode,
3909 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3910 but as registers instead (AOP_REG) using the fReturnIdx array,
3911 * (pic16_freeAsmop): remove the freed register from the
3912 _G.sregsAlloc field,
3913 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3914 a compare of 'WREG',
3915 * (pic16_popGetTempRegCond): changed function prototype, now
3916 function takes also a bitVector argument v which holds the current
3917 set of registers that are allocated for stack access by aopForSym,
3918 registers allocated in aopForSym for accessing stack symbols are not
3919 any more part of the functions usedRegs field,
3920 * (genCall): some times aopOp is called for a stack variable to be
3921 send, aopForSym might perform the push, if this is true make sure
3922 that genCall doesn't push the variable twice by testing _G.resDirect,
3923 * (genFunction): changed testing for unspecified interrupt number
3924 from 256 to INTNO_UNSPEC,
3925 * modified selection scheme of frame pointer generation. Previously
3926 if function did use local registers a frame pointer was generated,
3927 now a frame pointer is generated only if function has arguments
3928 (that need PLUSW2 register access), or has stack arguments, or the
3929 compiler is not instructed to omit the frame pointer,
3930 * (genEndFunction): before restoring local registers that were saved
3931 in the function preamble, also restore the registers that *might*
3932 have been allocated for stack access,
3933 * (genRet): removed some old comments,
3934 * (genCmp, the active (RN's) version): added a call to the
3935 pic16_genCmp_special function to perform the compare with a more
3936 robust and optimized way,
3937 * (genInline): a feature has been added in inline code generation,
3938 which allows a wildcard variable substitution when writing inline
3939 assembly. Code is incomplete and experimental therefore undocumented,
3940 * (genCast): changed order of aopOp for result and right to allow
3941 aopForSym to directly load the result if possible,
3942 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3943 perform an optimized compare on some selected special occasions,
3944 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3945 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3946 generate an IVT any more,
3947 * src/pic16/main.c (pic16_optionsTable): added command line option
3949 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3950 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3952 * src/pic16/NOTES: Raphael Neider added in list of active developers
3953 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3954 jumptable_end to prevent bug #,
3955 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3956 inCond and outCond fields,
3957 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3958 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3959 turn off register spilling,
3960 * (packRegsForOneUse): synced with other ports' versions although it
3961 is not used currently,
3962 * (pic16_packRegisters): added an optimization while reading
3963 structure bitfields, some registers may be saved (malloc code is
3964 decreased by 80 bytes)
3966 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3968 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3969 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3970 this can be optimized more?
3972 2005-03-10 Raphael Neider <rneider AT web.de>
3974 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3975 genNearPointerGet): (hopefully) fixed access to bitfields via
3976 pointers (p->bitN = x; and x = p->bitN; failed)
3978 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3980 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4019 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4021 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4022 to keep the correct label reference count when adding/removing references
4023 to labels. A peephole file using this is appended to patch #1144962.

4166 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4167 this might fix SIGSEGVs on MinGW...

4259 copy the third byte from the int -- now assumes 0x80 (data memory)
4260 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping

4611 generated for switch statements. For now you need to set the
4612 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4613 Now 4 algorithms for mcs51 jumptable generation are used:
4614 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4648 * added libc directory. The current version of LibC contains string
4649 functions, ctype functions and macros and some functions of the
4650 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4651 be extensively tested in the future. Standard disclaimer here.

4665 * (genCmp): experimental code for new genCmp which uses PIC18's
4666 special compare&skip instructions. Initial tests fail some times
4667 with variables grater than 1 byte in size, so new code is disabled,
4668 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4670 * (genCast): began a fix to optimize the casting of a bit to another
4671 bit, now assigning a bitfield to another bitfield will fail, sorry,

4686 * src/pic16/ralloc.c (allocReg): add preliminary support for
4687 supporting a limited set of temporary registers,
4689 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4713 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4715 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7694 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7696 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7697 loaded with the linker search paths (-L arguments) and the libraries
7698 to be linked with the current source (-l arguments). Changes
7699 currently will affect only the pic16 port.
7700 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7701 include path the port specific paths and port specific libraries,
7702 * gplink command now contains the $3 argument,
7703 * src/pic16/device.h,
7704 * src/pic16/device.c,: structure PIC_device is made public and
7705 renamed to PIC16_device, the same for variable Pics which is renamed

7720 Documenting changes from previous commits.
7721 * configure.in (version 1.56),
7722 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7723 when generating output files to configure the pic16 library,
7724 but now I've commented it out, since gputils aren't installed in the
7725 SF compile farm, so library won't compile
7727 * device/lib/Makefile.in (version 1.56): initially I've added in
7728 target 'all' the prerequestive 'model-pic16' so it compiled the
7729 pic16 library, but now I've commented it out for the same reasons
7731 * added targets 'model-pic16' and 'objects-pic16' to compile the
7733 * added target 'port-specific-objects-pic16' to handle the
7734 generated libraries and copy them into the build/ directory
7735 * added target 'clean-intermediate-pic16' to clean intermediate
7736 files into pic16 directory
7737 * in target 'installdirs' added line to create directory pic16 in
7738 the installation path

7741 added lines to copy all header files to installation path,
7742 * in target 'installdirs' added line create directory for pic16
7743 headers in the installation path

7758 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7759 option so that it actually works. Made it specific to the z80, since
7760 the gbz80 doesn't have these kinds of I/O ports.
7762 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7764 * device/include/z180.h,

7788 via literal number. The symbol is placed in the corresponding
7789 position of the data ram
7790 * (pic16_dump_section): relocatable and absolute uninitialized
7791 data are now emitted in sorted order to reduce section naming,
7792 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7793 weren't marked as being in the access bank,
7795 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7797 Added portion of GNU PIC Library under the directory
7798 device/include/pic16 and device/lib/pic16. These files
7799 contain the declarations of SFRs for the PIC18Fxx2 devices.
7800 The directory is initialized via configure from toplevel.
7802 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7830 all over. Telling LaTeX to be less strict with word spacing
7831 to better keep the right margin. Changed some notes about
7832 maintainance of the ports in section 3.2.1 - is it OK like this?
7834 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7843 processor registers declared internally by the port are emitted in
7844 the translation as equates,
7845 * src/pic16/gen.c: inline code is passed unprocessed to the

7988 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7989 (default behaviour).
7991 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7993 A python script to validate compiler diagnostic messages. It can be

8028 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8030 PIC16 port related changes:
8031 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8032 added variable stackPos,
8034 * gen.c: genCall, assignResultValue: added support for
8035 pushing/retrieving function parameters to/from stack,
8036 genFunction,genEndFunction: setup stack frame for the
8038 genAddrOf: will be changed according to bug 863624
8040 * added files genutils.c and genutils.h which contain gen*
8041 debugged and optimised functions extracted from gen.c
8043 * glue.c: added variable 'externs' which holds extern symbols,
8044 pic16emitRegularMap: is modified to properly handle relocatable
8045 symbols under the new scheme,
8046 pic16createInterruptVect: is modified
8047 pic16printPublics: is modified to emit 'global' assembler directives,
8048 added pic16_printExterns to print extern symbols,
8049 pic16glue: initializes stack/frame pointer in the beginning of
8050 the assembly output. Temporary hack, will be corrected later,
8051 because gplink yet does not support stack and SDCC does not
8052 yet support a type of crt0.o object to create the final binary.
8054 * Removed many lines that contain 8051 legacy code.
8055 * The code is finally placed under a 'code' directive.
8056 * Added port specific options.
8058 * _process_pragma: simplified since now we do not need *special*
8059 include file to define SFR registers. But a separate header
8060 will be needed. This will be developed later.
8061 * _pic16_parseOptions: added, parses port specific options:
8062 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8063 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8064 --preplace-udata-with=
8066 * _pic16_setDefaultOptions: modified to initialize section names,
8067 but hack is temporarly out of order since it needs improvement.
8068 * _pic16_genAssemblerPreamble: configuration words are emitted by
8069 their address instead of their name. This part is incomplete and
8070 supports only the 18Fxx2 devices. Other devices will emit an error
8071 during assembly since they do not contain the same set of config
8073 * _pic16_genIVT: is modified,
8075 * pcode.c: added definitions for some hardware registers that are needed
8077 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8078 All PCI entries are updated. Now LFSR is supported.
8079 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8080 * added pic16_newpCodeOpLit2 to support instructions with
8081 two literal arguments
8082 * pic16_pCode2str: corrected code that emits assembler instructions
8083 with two literal operands and those that have an access bit modifier
8084 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8085 this fixes a bug which caused some labels to be lost, when an
8086 assembler directive was added, i.e. banksel,
8087 * pic16_FixRegisterBanking: improved logic that causes the insertion
8089 * InlineFunction: functions that are called once, are not any more
8090 inlined. This can be a port option in the future,
8092 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8094 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8095 hold the corresponding uninitialized symbols,
8096 * pic16_allocProcessorRegister: registers have explicit marked the
8098 * pic16_allocInternalRegister: registers are explicit marked as
8100 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8101 processing list, so bit registers were lost,
8104 * ralloc.h: added field 'accessBank' and original symbol operand
8105 in register definition,
8106 * removed the field isMapped from register definition,
8108 ** Several functions have been removed from various sources:
8109 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8110 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8111 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8112 pic16_assignRelocatableRegisters
8114 ** others have been introduced:
8115 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8116 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8118 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8120 * support/scripts/inc2h.pl: changed definition of BIT_AT
8121 to emit 'sbit at' instead of 'bit at'. This was a request.
8123 PIC16 port related preliminary changes:
8124 * gen.c: prefixed function popRegFromString with
8125 pic16_ and all references to it corrected
8126 * pcode.c: all pic16_pc_* hardware registers prefixed
8127 with underscore (_),
8128 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8129 * ralloc.c: newReg(): when register is REG_SFR then
8130 set address to rIdx,
8131 pic16_allocProcessorRegister(): marks register wasUsed=0
8132 pic16_writeUsedRegs(): added a call to assign processor
8133 registers via pic16_assignFixedRegisters
8135 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8137 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8138 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8139 variables in unused register banks. Also the SSEG is placed
8140 wherever there is enough space for it, and IDATA can be anywhere
8141 in internal RAM. For now compile using -Wl-Y[stack_size].
8142 The mem file is different for this option as well, since it
8143 makes no sense of talking about DSEG lenght.
8145 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8147 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8148 in certain cases, e.g. when ROM assignment, patch provided
8149 from Albert den Haan.
8151 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8294 * src/mcs51/peephole.def,
8295 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8296 (allows non-interrupt and interrupt code to safely compete for a resource

9036 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9037 support for standard C idiom of memory mapped variables; for
9038 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9039 to xdata int at 0x1234 tempvar = 1.
9040 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9041 provided by Akiya ISHIDA

9057 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9059 Fixed bug #621531 (const & volatile confusion in the type chain).
9060 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9061 refer to the const or volatile state of the pointer itself.

9126 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9127 pcoderegs.h, ralloc.c, ralloc.h
9128 * main.c: added top header and GPL license notice

9152 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9153 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9154 fetching of the pointer
9155 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9156 copied from genNearPointerSet()
9157 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9158 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9159 If they pop r0/r1 they must be called in the opposite order than aopOp().
9160 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9161 (resp. --stack-auto), prepared for --xstack

9170 these ports have their own __sdcc_external_start()
9172 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9174 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9175 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9176 type for bits was changed. It resulted in bit variables becoming
9177 global, which is not permitted in PIC 14 assembly output.
9179 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9181 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9192 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9194 A few small changes that speed up the peephole optimizer.
9198 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9200 Try to make the peephole optimizer smarter by maintaining
9201 an association between the assembly source code and the
9202 iCodes that originated them. Put this information to use
9203 with a new peephole rule condition "notVolatile" so that
9204 the rules can be aggressive yet still safe.
9209 * src/mcs51/peeph.def
9211 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9215 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9216 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9217 if the left or right operand symbols have the accuse flag set.
9219 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9221 Changed the type of the result of the ! (NOT) operator to char;
9222 previously it returned the same type as the source. This allows
9223 us to eliminate all the genFloatNot functions (all of its target
9224 implementations were very buggy) since !float can use the same
9227 * src/SDCCicode.c (ast2iCode): ! returns char
9228 * src/mcs51/gen.c (genNot, genNotFloat),
9229 * src/ds390/gen.c (genNot, genNotFloat),
9230 * src/z80/gen.c (genNot, genNotFloat),
9231 * src/pic/gen.c (genNot, genNotFloat),
9232 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9234 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9236 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9237 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9238 during interrupts. Ensure WSAVE is located at a shared bank address.
9239 2. Fixed page selection in some places
9240 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9241 the registers name strings.
9242 4. Fixed "signed / unsigned compare" compiler warnings.
9243 5. The PIC port manages its own allocation of the general purpose
9244 registers, but makes no attempt to reuse them. As a result when
9245 compiling it soon runs out of general purpose registers. Some
9246 additional code was added to the files pcode.c and device.c to walk
9247 through the function call tree and rename the registers so that they
9257 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9258 genPlus() & genMinus() when the result is the same as left or right
9260 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9264 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9266 Made bitfield a distinct type from bit so that bitfields
9267 convert as per ANSI C and bits retain their traditional
9268 boolean style behaviour. Implemented bitfield support in
9276 * src/ds390/gen.c: bit v bitfield split
9277 * src/z80/gen.c: New support for bitfields
9278 * support/regression/tests/bitfields.c: reenabled z80,
9281 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9283 Rules 246.x, 247.x relate to bitfields, the others speed up
9284 access to xdata mapped I/O devices.
9286 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9288 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9290 Cleaned up genPackBits and genUnpackBits and added two helper
9291 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9292 for literal assignments in genPackBits (thanks to Frieder for
9298 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9300 Fixed bug #748310 (pointer to function type mishandled when the
9301 function name is omitted). Also fixed a SIGSEGV when a function
9302 attribute (reentrant, etc) is used on a non-function or on a
9303 function but misplaced before the parameter list.
9305 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9307 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9308 * support/Util/SDCCerr.h,
9309 * support/Util/SDCCerr.c: Added func attr misuse error msg
9311 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9313 Fixed bug #787649 by anonymous
9314 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9315 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9317 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9319 Fixed numerous bitfield problems.
9321 * src/SDCC.y: More bitfield related error checking
9323 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
9324 * support/Util/SDCCerr.h,
9325 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs

9327 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
9328 * support/regression/tests/bitfields.c: tests added
9330 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9332 Made the constant following the "interrupt" keyword optional. If
9333 omitted, the function will not automatically be given an entry
9334 in the interrupt vector table (similar to #pragma NOIV, but
9335 less syntacticly kludgy). The interrupt number is also now
9336 range checked. Also fixed a bug in the high order bit example
9343 * support/Util/SDCCerr.c
9344 * support/Util/SDCCerr.h
9347 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9349 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9350 * src/SDCCicode.c (operandOperation): rewritten some ops
9351 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9352 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9354 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9355 be re-activated by defining REDUCE_LITERALS)

9866 added if/endif conditional macros to remove options help
9867 messages from optionsTable when a port is not configured, added
9868 support for the PIc16 port in the ports table, when executing
9869 the compiler with no port specified on command line, a default
9870 port is selected with the new macro DEFAULT_PORT which is
9871 defined in port.h, in setDefaultOptions() linkOptions is removed
9872 from initialization assignment, since now it is a set,
9873 parseCmdLine uses setParseWithComma for linkOptions, in
9874 linkEdit() linkOptions are accessed with new function indexSet()
9875 which returns the i'th item of a set variable. See SDCCset.c, in
9876 linkEdit() when calling buildCmdLine(), added linkOptions as
9877 last argument. Now users can pass arguments to gplink via the
9878 -Wl option, main() uses pic16glue() to glue up pic16 programs

9892 gpasm complaining and test the linkage with gplink, _linkCmd and
9893 _asmCmd changed to be more gplink and gpasm friendly
9894 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9895 produced an error when parsed, peep rule 12 is added to utilize
9896 movff, but it is commented out since the pCode does not support
9897 yet a command with 2 address arguments
9899 2003-05-18 <johan AT balder>
9901 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10949 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10950 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10956 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10957 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10959 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10960 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10962 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10964 * in /sdcc/as/mcs51/ changed these files in order to create an
10965 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10966 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10967 following files to include the previous two files: aslink.dsp,
10968 Makefile.aslink, Makefile.bcc, and Makefile.in.
10970 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10971 .adb instead of .cdb
10973 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10975 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10976 value from option --iram-size.
10978 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10980 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10983 2002-09-18 <wiml AT hhhh.org>
10985 * SDCClrange.h: exposed setFromRange() and setToRange()
10986 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10987 packRegsForAccUse() (bug 542397)
10988 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10989 multiple times and emitting the fetch operations more than once
10990 added aopGetUsesAcc() function to allow binary operators to
10991 fetch their operands in the correct order; made genMinus() emit
10992 compact code for X = LITERAL - Y
10994 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10995 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10996 sprintf() in line 1267.
10998 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10999 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11002 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11003 Changes to aslink (All the changes are marked with 'JCF'):
11005 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11008 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11009 area BSEG. Also moves, if possible, the DATA area down into the internal
11010 ram so more space is available.
11012 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11015 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11016 not bytes. Function summary() which creates a memory usage summary
11017 file with extension .mem. Reports of overlaping stack and small stack
11018 size. If the space for the stack is less than 16 bytes aslink trows a
11021 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11022 the 8051. Option 'y' for memory summary output file.
11024 Changes to sdcc (All the changes are marked with 'JCF'):
11026 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11028 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11029 overlaying area for it (uses RegBankUsed[4]).
11031 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11032 bank zero as used by default. By default aslink locates the stack
11033 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11034 the creation of the .mem file. Delegates the allocation of data area
11035 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11036 the begining of the stack area to aslink.
11038 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11039 glue() in SDCCglue.c creates an area for it.
11041 2002-09-03 Borut Razem <borut.razem AT siol.net>
11042 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11043 sdcc/src/pic/glue.c:
11044 introduced atexit() handler for teporay files removal in case of
11045 errors, assertions, ...
11047 2002-08-29 Borut Razem <borut.razem AT siol.net>
11048 * sdcc/support/cpp2/auto-host_vc_in.h:
11049 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11050 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11051 Maybe there is a similar problem with BORLANDC? It should be checked!
11053 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11054 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11055 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11056 was not executed, and the compiler (cl) launched a warning:
11057 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11059 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11060 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11062 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11063 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11065 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11066 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11067 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11068 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11069 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11070 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11071 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11072 - added Release configuration in VS projects
11073 - review of compiler an linker options
11074 - VC .exe files are generated in bin_vc directory, not to interfere
11075 with binaries generated from other projects (cygwin, mingw, bcc ...)
11077 * sdcc/src/yacc.dsp: added
11079 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11080 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11081 and insert the version number definitions from .version
11083 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11085 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11086 added - genarate auto-host.h using auto-host_vc_in.h as template
11089 removed from CVS, generated automatically
11091 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11092 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11094 2002-08-11 Borut Razem <borut.razem AT siol.net>
11095 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11097 2002-08-10 Borut Razem <borut.razem AT siol.net>
11098 * src/SDCCmain.c (main):
11099 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11100 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11101 The consequence was that some temporary files were not removed.
11104 unification of code in functions tempfilename() and tempfile():
11105 function tempnam() is defined in Visual Studio 6.0 and .NET
11107 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11109 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11110 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11111 - removed compiler command line option /WX: Treats all warnings as errors
11112 - update a list of source files, included into the project
11114 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11115 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11116 changed project type to Generic Project so that can be correcly converted to VS.NET project
11118 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11120 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11122 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11124 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11125 added return 0 statements after assert() to make compiler happy
11127 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11128 added newline in the def file to keep MSC compiler satisfied
11130 * sdcc/src/z80/gen.c:
11131 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11132 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11133 - solved MSC error in function aopDump()
11135 * sdcc_vc.h: define PREFIX as "\\sdcc"
11137 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11138 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11140 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11141 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11142 - Rewrote the register banking algorithm.
11143 - Added pCode live-range analysis to registers (for now, only non-used and
11144 singly-used registers optimized away)
11146 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11148 * 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.
11150 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11151 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

11163 2002-04-15 Michael Hope <michaelh AT vroom>
11165 * device/lib/z80/printf.c (sprintf): Added.
11167 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11169 * src/z80/peeph.def: Added transpose redundent load rule.
