1111 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1112 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1114 One basic decision: e.g. src/clean.mk includes further files. In order
1115 to make this work there are two solutions:
1116 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1117 run configure on them. This way they can use
1118 'include $(srcdir)/port-clean.mk'
1119 - always include clean.mk by the Makefile at the same level. To avoid
1120 that `make clean` tries to include and build Makefile.dep the
1121 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1122 implemented, because now even `make uninstall` doesn't create
1123 Makefile.in. clean.mk could be eliminated by pasting it in
1126 * debugger/mcs51/Makefile.in: build own objects from library sources
1127 (SLIB, SDCC) in current directory
1129 * configure, configure.in: renamed --disable-device-lib-build in
1130 --disable-device-lib; added --enable-doc, the required tools are
1131 searched by configure; added result message; the toolchain for the
1132 belonging ports are now only built, if the port is enabled.
1134 * support/regression/*: all output is written in directory gen, because
1135 the fwk and ports directories don't livet in the build tree using vpath
1137 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1138 --disable-device-lib, added --enable-doc, added section VPATH
1140 * sim/ucsim/configure.in,
1141 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1142 z80 are enabled by default
1144 2006-04-24 Raphael Neider <rneider AT web.de>
1146 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1147 to config word, "pic14_"-prefixed some extern functions
1148 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1149 config word has been found
1150 * src/pic/device.h: added prototypes
1151 * src/pic/pcode.c: added "pic14_"-prefix where needed
1152 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1154 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1157 (pic14createInterruptVect): moved generating __config directives away

1169 (pCodeRegOptimizeRegUsage): fixed typo in comment

1392 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1394 * src/mcs51/gen.c (genCall): fixed bug 1457608
1396 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1398 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1401 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1403 * src/SDCCpeeph.c (operandsLiteral): new, added,

1415 implemented patch 1120823 Thanks to Willy De la Court (normal
1416 interrupts need an interrupt number now if they are made critical),
1417 and enabled nesting of critical functions though not for gbz80
1418 (genCritical, genEndCritical): added functions
1419 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1420 * src/z80/mappings.i: added "ei" to all mappings
1422 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1424 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1425 submitted by the Debian SDCC maintainer Aurelien Jarno:
1426 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1427 archive with gcc 4.1 on mips and wrote the patch"
1429 2006-03-16 Raphael Neider <rneider AT web.de>
1431 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1432 the left operand is shorter than the result (c* = lit-c* + int),
1434 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1437 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1439 * src/.version: increased version number to 2.5.5
1440 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1441 linking is done manually in pic16 port's _linkEdit,
1442 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1443 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1444 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1445 allocate asmop as AOP_ACC,
1446 (aopForRemat): added parameter 'bool result' in function declaration,
1447 (pic16_aopGet): return AOP_ACC when accessing WREG,
1448 (pic16_popGetTempReg): minor modification,
1449 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1450 'pic16_allocWithIdx',
1451 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1452 calling function in absolute addresses,
1453 (genAssign): take into account AOP_ACC asmop,
1454 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1455 * src/pic16/pcoderegs.c: some debug functions and lines added,

1457 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1459 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1460 call to allocReg, not by manually allocating a new one,
1461 (pic16_assignRegisters): now before going through the register
1462 allocating functions mark all registers as free. This eliminates some
1463 side effects resulting from peephole parser done earlier in the backbone
1465 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1467 * src/SDCCicode.c (geniCodeLogic),

1486 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1487 (aopForSym, aopOp): increment asmop.allocated if reused,
1488 (freeAsmop): decrement asmop.allocated and check for zero instead of
1490 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1491 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1492 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1515 2006-03-06 Borut Razem <borut.razem AT siol.net>
1517 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1518 made the linker quiet
1520 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1522 * src/pic16/gen.c (genPcall): fixed bug #1443644
1523 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1524 which dumps before the function entry point a data byte which represents
1525 the number of the local variables used by the specified function, added
1526 'xinst' for initial support for Extended Instruction Support,
1527 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1528 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1529 port->fun_prefix anymore (may change later),
1530 (genFunction, genEndFunction): do not store/restore local registers for
1531 _main (this should take care the --main-return command line option in
1533 (genOr): removed some legacy pic-port instructions,
1534 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1535 performing operations with SFR's causes data to be written more than
1536 once to each SFR. Perhaps SFRs should be handled in special cases...
1537 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1539 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1540 into account for stack starting position,
1541 (struct OPTIONS pic16_optionsTable): added command line argument
1542 --extended or -y for Extended Instruction Support,
1543 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1544 (deassignLRs): *** perhaps the most important change, old 'for' code
1545 (commented out for reference), didn't account for some registers which
1546 were left marked 'not free' after a pointer operation. The change
1547 reduces register usage a lot in some cases
1549 2006-03-04 Borut Razem <borut.razem AT siol.net>
1551 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3873 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3874 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3875 immedDom() returning wrong block; probably fixes bug #1160833)
3877 2005-03-20 Borut Razem <borut.razem AT siol.net>
3879 * support/scripts/inc2h.pl: WIN32 port
3881 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3883 * device/lib/makefile.in: added abs.c and labs.c
3885 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3887 * device/include/stdint.h: added
3888 * device/lib/abs.c: added
3889 * device/lib/labs.c: added
3890 * device/include/stdlib.h: added abs() and labs() prototypes
3891 * device/lib/libsdcc.lib: added abs and labs
3892 * device/include/float.h,
3893 * device/lib/_fsmul.c,
3894 * device/lib/printf_fast.c,
3895 * device/lib/printf_tiny.c: updated comments
3897 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3899 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3902 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3904 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3905 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3907 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3909 * device/lib/printf_large.c: removed inline assembly for portability and
3910 readability. Use printf_fast if speed or size are more important.
3911 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3912 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3914 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3916 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3917 prevent compiler warning
3919 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3921 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3922 moved to level 0 and declared as static. Also they are explicit
3923 placed in access bank. This was necessery because some times they
3924 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3925 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3926 optimizations. Currently only compare to unsigned char is implemented,
3927 * src/pic16/gen.c: added fReturnIdx array,
3928 * (struct resolvedIfx) is moved to gen.h and made public,
3929 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3930 * (aopForSym): added an optimization to directly store in stack of
3931 the operand of a SEND iCode,
3932 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3933 but as registers instead (AOP_REG) using the fReturnIdx array,
3934 * (pic16_freeAsmop): remove the freed register from the
3935 _G.sregsAlloc field,
3936 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3937 a compare of 'WREG',
3938 * (pic16_popGetTempRegCond): changed function prototype, now
3939 function takes also a bitVector argument v which holds the current
3940 set of registers that are allocated for stack access by aopForSym,
3941 registers allocated in aopForSym for accessing stack symbols are not
3942 any more part of the functions usedRegs field,
3943 * (genCall): some times aopOp is called for a stack variable to be
3944 send, aopForSym might perform the push, if this is true make sure
3945 that genCall doesn't push the variable twice by testing _G.resDirect,
3946 * (genFunction): changed testing for unspecified interrupt number
3947 from 256 to INTNO_UNSPEC,
3948 * modified selection scheme of frame pointer generation. Previously
3949 if function did use local registers a frame pointer was generated,
3950 now a frame pointer is generated only if function has arguments
3951 (that need PLUSW2 register access), or has stack arguments, or the
3952 compiler is not instructed to omit the frame pointer,
3953 * (genEndFunction): before restoring local registers that were saved
3954 in the function preamble, also restore the registers that *might*
3955 have been allocated for stack access,
3956 * (genRet): removed some old comments,
3957 * (genCmp, the active (RN's) version): added a call to the
3958 pic16_genCmp_special function to perform the compare with a more
3959 robust and optimized way,
3960 * (genInline): a feature has been added in inline code generation,
3961 which allows a wildcard variable substitution when writing inline
3962 assembly. Code is incomplete and experimental therefore undocumented,
3963 * (genCast): changed order of aopOp for result and right to allow
3964 aopForSym to directly load the result if possible,
3965 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3966 perform an optimized compare on some selected special occasions,
3967 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3968 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3969 generate an IVT any more,
3970 * src/pic16/main.c (pic16_optionsTable): added command line option
3972 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3973 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3975 * src/pic16/NOTES: Raphael Neider added in list of active developers
3976 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3977 jumptable_end to prevent bug #,
3978 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3979 inCond and outCond fields,
3980 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3981 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3982 turn off register spilling,
3983 * (packRegsForOneUse): synced with other ports' versions although it
3984 is not used currently,
3985 * (pic16_packRegisters): added an optimization while reading
3986 structure bitfields, some registers may be saved (malloc code is
3987 decreased by 80 bytes)
3989 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3991 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3992 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3993 this can be optimized more?
3995 2005-03-10 Raphael Neider <rneider AT web.de>
3997 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3998 genNearPointerGet): (hopefully) fixed access to bitfields via
3999 pointers (p->bitN = x; and x = p->bitN; failed)
4001 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4042 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4044 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4045 to keep the correct label reference count when adding/removing references
4046 to labels. A peephole file using this is appended to patch #1144962.

4188 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4189 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4190 this might fix SIGSEGVs on MinGW...
4191 * src/SDCCopt.c (killDeadCode): restored original behaviour
4192 (volatile operands might get thrown away though)

4279 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4280 used uninitialized in some cases)

4282 copy the third byte from the int -- now assumes 0x80 (data memory)
4283 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4284 operands (genAddLit expects the iCode's operands to swapped as
4285 well), fixed leftover bytes (crashed for short left operands)

4635 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4636 Now 4 algorithms for mcs51 jumptable generation are used:
4637 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4669 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4671 * added libc directory. The current version of LibC contains string
4672 functions, ctype functions and macros and some functions of the
4673 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4674 be extensively tested in the future. Standard disclaimer here.
4675 Library is not automatically build yet. But one can build it by

4687 * (pic16_storeForReturn): optimized return of 0,
4688 * (genCmp): experimental code for new genCmp which uses PIC18's
4689 special compare&skip instructions. Initial tests fail some times
4690 with variables grater than 1 byte in size, so new code is disabled,
4691 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4693 * (genCast): began a fix to optimize the casting of a bit to another
4694 bit, now assigning a bitfield to another bitfield will fail, sorry,

4703 and 1 for banking instruction,
4704 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4705 caused stop processing pCodes after a inline assembly block,
4706 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4708 registers when it shouldn't,
4709 * src/pic16/ralloc.c (allocReg): add preliminary support for
4710 supporting a limited set of temporary registers,
4712 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4715 genDataPointerSet): ensure assignments always copy in MSB to LSB
4717 (loadRegFromAop): recognize CLRH optimization,
4718 (genFunction): optimize RECEIVE iCodes in reentrant functions
4720 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4722 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7717 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7719 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7720 loaded with the linker search paths (-L arguments) and the libraries
7721 to be linked with the current source (-l arguments). Changes
7722 currently will affect only the pic16 port.
7723 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7724 include path the port specific paths and port specific libraries,
7725 * gplink command now contains the $3 argument,
7726 * src/pic16/device.h,
7727 * src/pic16/device.c,: structure PIC_device is made public and
7728 renamed to PIC16_device, the same for variable Pics which is renamed

7743 Documenting changes from previous commits.
7744 * configure.in (version 1.56),
7745 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7746 when generating output files to configure the pic16 library,
7747 but now I've commented it out, since gputils aren't installed in the
7748 SF compile farm, so library won't compile
7750 * device/lib/Makefile.in (version 1.56): initially I've added in
7751 target 'all' the prerequestive 'model-pic16' so it compiled the
7752 pic16 library, but now I've commented it out for the same reasons
7754 * added targets 'model-pic16' and 'objects-pic16' to compile the
7756 * added target 'port-specific-objects-pic16' to handle the
7757 generated libraries and copy them into the build/ directory
7758 * added target 'clean-intermediate-pic16' to clean intermediate
7759 files into pic16 directory
7760 * in target 'installdirs' added line to create directory pic16 in
7761 the installation path
7763 * device/include/Makefile.in (version 1.11): in target 'install'
7764 added lines to copy all header files to installation path,
7765 * in target 'installdirs' added line create directory for pic16
7766 headers in the installation path

7781 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7782 option so that it actually works. Made it specific to the z80, since
7783 the gbz80 doesn't have these kinds of I/O ports.
7785 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7787 * device/include/z180.h,

7811 via literal number. The symbol is placed in the corresponding
7812 position of the data ram
7813 * (pic16_dump_section): relocatable and absolute uninitialized
7814 data are now emitted in sorted order to reduce section naming,
7815 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7816 weren't marked as being in the access bank,
7818 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7820 Added portion of GNU PIC Library under the directory
7821 device/include/pic16 and device/lib/pic16. These files
7822 contain the declarations of SFRs for the PIC18Fxx2 devices.
7823 The directory is initialized via configure from toplevel.
7825 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7850 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7852 * doc/sdccman.lyx: Moved and added some sections, small changes
7853 all over. Telling LaTeX to be less strict with word spacing
7854 to better keep the right margin. Changed some notes about
7855 maintainance of the ports in section 3.2.1 - is it OK like this?
7857 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8009 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8011 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8012 (default behaviour).
8014 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8016 A python script to validate compiler diagnostic messages. It can be
8017 used to verify that sdcc complains about bad c source code and
8018 gives a good location of the error.
8019 * support/valdiag/Makefile,
8020 * support/valdiag/valdiag.py,
8021 * support/valdiag/tests/*

8036 * src/common.h: added ifndef/define/endif macros
8037 around the header file.
8038 Bug reported from Jesus Calvino-Fraga
8040 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8042 * sdcc.spec: updated
8043 * device/include/Makefile.in: don't install CVS directories
8044 * device/lib/Makefile.in: added removal of CVS directories after install
8045 * doc/Makefile: fixed install, added local_icons
8046 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8047 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8048 * src/ds390/gen.c (genRightShift): fixed bug #870788
8049 * src/SDCCast.c (decorateType): fixed bug #870781
8051 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8053 PIC16 port related changes:
8054 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8055 added variable stackPos,
8057 * gen.c: genCall, assignResultValue: added support for
8058 pushing/retrieving function parameters to/from stack,
8059 genFunction,genEndFunction: setup stack frame for the
8061 genAddrOf: will be changed according to bug 863624
8063 * added files genutils.c and genutils.h which contain gen*
8064 debugged and optimised functions extracted from gen.c
8066 * glue.c: added variable 'externs' which holds extern symbols,
8067 pic16emitRegularMap: is modified to properly handle relocatable
8068 symbols under the new scheme,
8069 pic16createInterruptVect: is modified
8070 pic16printPublics: is modified to emit 'global' assembler directives,
8071 added pic16_printExterns to print extern symbols,
8072 pic16glue: initializes stack/frame pointer in the beginning of
8073 the assembly output. Temporary hack, will be corrected later,
8074 because gplink yet does not support stack and SDCC does not
8075 yet support a type of crt0.o object to create the final binary.
8077 * Removed many lines that contain 8051 legacy code.
8078 * The code is finally placed under a 'code' directive.
8079 * Added port specific options.
8081 * _process_pragma: simplified since now we do not need *special*
8082 include file to define SFR registers. But a separate header
8083 will be needed. This will be developed later.
8084 * _pic16_parseOptions: added, parses port specific options:
8085 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8086 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8087 --preplace-udata-with=
8089 * _pic16_setDefaultOptions: modified to initialize section names,
8090 but hack is temporarly out of order since it needs improvement.
8091 * _pic16_genAssemblerPreamble: configuration words are emitted by
8092 their address instead of their name. This part is incomplete and
8093 supports only the 18Fxx2 devices. Other devices will emit an error
8094 during assembly since they do not contain the same set of config
8096 * _pic16_genIVT: is modified,
8098 * pcode.c: added definitions for some hardware registers that are needed
8100 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8101 All PCI entries are updated. Now LFSR is supported.
8102 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8103 * added pic16_newpCodeOpLit2 to support instructions with
8104 two literal arguments
8105 * pic16_pCode2str: corrected code that emits assembler instructions
8106 with two literal operands and those that have an access bit modifier
8107 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8108 this fixes a bug which caused some labels to be lost, when an
8109 assembler directive was added, i.e. banksel,
8110 * pic16_FixRegisterBanking: improved logic that causes the insertion
8112 * InlineFunction: functions that are called once, are not any more
8113 inlined. This can be a port option in the future,
8115 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8117 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8118 hold the corresponding uninitialized symbols,
8119 * pic16_allocProcessorRegister: registers have explicit marked the
8121 * pic16_allocInternalRegister: registers are explicit marked as
8123 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8124 processing list, so bit registers were lost,
8127 * ralloc.h: added field 'accessBank' and original symbol operand
8128 in register definition,
8129 * removed the field isMapped from register definition,
8131 ** Several functions have been removed from various sources:
8132 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8133 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8134 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8135 pic16_assignRelocatableRegisters
8137 ** others have been introduced:
8138 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8139 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8141 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8143 * support/scripts/inc2h.pl: changed definition of BIT_AT
8144 to emit 'sbit at' instead of 'bit at'. This was a request.
8146 PIC16 port related preliminary changes:
8147 * gen.c: prefixed function popRegFromString with
8148 pic16_ and all references to it corrected
8149 * pcode.c: all pic16_pc_* hardware registers prefixed
8150 with underscore (_),
8151 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8152 * ralloc.c: newReg(): when register is REG_SFR then
8153 set address to rIdx,
8154 pic16_allocProcessorRegister(): marks register wasUsed=0
8155 pic16_writeUsedRegs(): added a call to assign processor
8156 registers via pic16_assignFixedRegisters
8158 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8160 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8161 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8162 variables in unused register banks. Also the SSEG is placed
8163 wherever there is enough space for it, and IDATA can be anywhere
8164 in internal RAM. For now compile using -Wl-Y[stack_size].
8165 The mem file is different for this option as well, since it
8166 makes no sense of talking about DSEG lenght.
8168 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8170 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8171 in certain cases, e.g. when ROM assignment, patch provided
8172 from Albert den Haan.
8174 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8317 * src/mcs51/peephole.def,
8318 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8319 (allows non-interrupt and interrupt code to safely compete for a resource

9197 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9198 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9199 type for bits was changed. It resulted in bit variables becoming

9217 A few small changes that speed up the peephole optimizer.
9221 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9223 Try to make the peephole optimizer smarter by maintaining
9224 an association between the assembly source code and the
9225 iCodes that originated them. Put this information to use
9226 with a new peephole rule condition "notVolatile" so that
9227 the rules can be aggressive yet still safe.
9232 * src/mcs51/peeph.def
9234 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9238 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9239 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9240 if the left or right operand symbols have the accuse flag set.
9242 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9244 Changed the type of the result of the ! (NOT) operator to char;
9245 previously it returned the same type as the source. This allows
9246 us to eliminate all the genFloatNot functions (all of its target
9247 implementations were very buggy) since !float can use the same
9250 * src/SDCCicode.c (ast2iCode): ! returns char

9259 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9260 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9261 during interrupts. Ensure WSAVE is located at a shared bank address.
9262 2. Fixed page selection in some places
9263 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9264 the registers name strings.
9265 4. Fixed "signed / unsigned compare" compiler warnings.
9266 5. The PIC port manages its own allocation of the general purpose
9267 registers, but makes no attempt to reuse them. As a result when
9268 compiling it soon runs out of general purpose registers. Some
9269 additional code was added to the files pcode.c and device.c to walk
9270 through the function call tree and rename the registers so that they
9280 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9287 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9289 Made bitfield a distinct type from bit so that bitfields
9290 convert as per ANSI C and bits retain their traditional
9291 boolean style behaviour. Implemented bitfield support in
9299 * src/ds390/gen.c: bit v bitfield split
9300 * src/z80/gen.c: New support for bitfields
9301 * support/regression/tests/bitfields.c: reenabled z80,
9304 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9306 Rules 246.x, 247.x relate to bitfields, the others speed up
9307 access to xdata mapped I/O devices.
9309 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9311 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9313 Cleaned up genPackBits and genUnpackBits and added two helper

9323 Fixed bug #748310 (pointer to function type mishandled when the
9324 function name is omitted). Also fixed a SIGSEGV when a function
9325 attribute (reentrant, etc) is used on a non-function or on a
9326 function but misplaced before the parameter list.

9353 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9355 Made the constant following the "interrupt" keyword optional. If
9356 omitted, the function will not automatically be given an entry
9357 in the interrupt vector table (similar to #pragma NOIV, but
9358 less syntacticly kludgy). The interrupt number is also now
9359 range checked. Also fixed a bug in the high order bit example
9366 * support/Util/SDCCerr.c
9367 * support/Util/SDCCerr.h

9892 the compiler with no port specified on command line, a default
9893 port is selected with the new macro DEFAULT_PORT which is
9894 defined in port.h, in setDefaultOptions() linkOptions is removed
9895 from initialization assignment, since now it is a set,
9896 parseCmdLine uses setParseWithComma for linkOptions, in
9897 linkEdit() linkOptions are accessed with new function indexSet()

10979 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10980 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10982 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10983 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10985 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10987 * in /sdcc/as/mcs51/ changed these files in order to create an
10988 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10989 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10990 following files to include the previous two files: aslink.dsp,
10991 Makefile.aslink, Makefile.bcc, and Makefile.in.
10993 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10994 .adb instead of .cdb
10996 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10998 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10999 value from option --iram-size.
11001 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11003 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11006 2002-09-18 <wiml AT hhhh.org>
11008 * SDCClrange.h: exposed setFromRange() and setToRange()
11009 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11010 packRegsForAccUse() (bug 542397)
11011 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11012 multiple times and emitting the fetch operations more than once
11013 added aopGetUsesAcc() function to allow binary operators to
11014 fetch their operands in the correct order; made genMinus() emit
11015 compact code for X = LITERAL - Y
11017 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11018 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11019 sprintf() in line 1267.
11021 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11022 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11025 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11026 Changes to aslink (All the changes are marked with 'JCF'):
11028 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11031 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11032 area BSEG. Also moves, if possible, the DATA area down into the internal
11033 ram so more space is available.
11035 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11038 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11039 not bytes. Function summary() which creates a memory usage summary
11040 file with extension .mem. Reports of overlaping stack and small stack
11041 size. If the space for the stack is less than 16 bytes aslink trows a
11044 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11045 the 8051. Option 'y' for memory summary output file.
11047 Changes to sdcc (All the changes are marked with 'JCF'):
11049 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11051 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11052 overlaying area for it (uses RegBankUsed[4]).
11054 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11055 bank zero as used by default. By default aslink locates the stack
11056 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11057 the creation of the .mem file. Delegates the allocation of data area
11058 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11059 the begining of the stack area to aslink.
11061 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11062 glue() in SDCCglue.c creates an area for it.
11064 2002-09-03 Borut Razem <borut.razem AT siol.net>
11065 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11066 sdcc/src/pic/glue.c:
11067 introduced atexit() handler for teporay files removal in case of
11068 errors, assertions, ...
11070 2002-08-29 Borut Razem <borut.razem AT siol.net>
11071 * sdcc/support/cpp2/auto-host_vc_in.h:
11072 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11073 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11074 Maybe there is a similar problem with BORLANDC? It should be checked!
11076 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11077 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11078 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11079 was not executed, and the compiler (cl) launched a warning:
11080 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11082 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11083 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11085 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11086 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11088 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11089 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11090 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11091 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11092 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11093 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11094 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11095 - added Release configuration in VS projects
11096 - review of compiler an linker options
11097 - VC .exe files are generated in bin_vc directory, not to interfere
11098 with binaries generated from other projects (cygwin, mingw, bcc ...)
11100 * sdcc/src/yacc.dsp: added
11102 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11103 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11104 and insert the version number definitions from .version
11106 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11108 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11109 added - genarate auto-host.h using auto-host_vc_in.h as template
11112 removed from CVS, generated automatically
11114 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11115 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11117 2002-08-11 Borut Razem <borut.razem AT siol.net>
11118 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11120 2002-08-10 Borut Razem <borut.razem AT siol.net>
11121 * src/SDCCmain.c (main):
11122 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11123 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11124 The consequence was that some temporary files were not removed.
11127 unification of code in functions tempfilename() and tempfile():
11128 function tempnam() is defined in Visual Studio 6.0 and .NET
11130 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11132 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11133 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11134 - removed compiler command line option /WX: Treats all warnings as errors
11135 - update a list of source files, included into the project
11137 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11138 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11139 changed project type to Generic Project so that can be correcly converted to VS.NET project
11141 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11143 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11145 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11147 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11148 added return 0 statements after assert() to make compiler happy
11150 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11151 added newline in the def file to keep MSC compiler satisfied
11153 * sdcc/src/z80/gen.c:
11154 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11155 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11156 - solved MSC error in function aopDump()
11158 * sdcc_vc.h: define PREFIX as "\\sdcc"
11160 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11161 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11163 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11164 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11165 - Rewrote the register banking algorithm.
11166 - Added pCode live-range analysis to registers (for now, only non-used and
