1093 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1095 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1096 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1098 One basic decision: e.g. src/clean.mk includes further files. In order
1099 to make this work there are two solutions:
1100 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1101 run configure on them. This way they can use
1102 'include $(srcdir)/port-clean.mk'
1103 - always include clean.mk by the Makefile at the same level. To avoid
1104 that `make clean` tries to include and build Makefile.dep the
1105 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1106 implemented, because now even `make uninstall` doesn't create
1107 Makefile.in. clean.mk could be eliminated by pasting it in
1110 * debugger/mcs51/Makefile.in: build own objects from library sources
1111 (SLIB, SDCC) in current directory
1113 * configure, configure.in: renamed --disable-device-lib-build in
1114 --disable-device-lib; added --enable-doc, the required tools are
1115 searched by configure; added result message; the toolchain for the
1116 belonging ports are now only built, if the port is enabled.
1118 * support/regression/*: all output is written in directory gen, because
1119 the fwk and ports directories don't livet in the build tree using vpath
1121 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1122 --disable-device-lib, added --enable-doc, added section VPATH
1124 * sim/ucsim/configure.in,
1125 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1126 z80 are enabled by default
1128 2006-04-24 Raphael Neider <rneider AT web.de>
1130 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1131 to config word, "pic14_"-prefixed some extern functions
1132 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1133 config word has been found
1134 * src/pic/device.h: added prototypes
1135 * src/pic/pcode.c: added "pic14_"-prefix where needed
1136 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1138 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1140 (pic14emitRegularMap): ignore config words,
1141 (pic14createInterruptVect): moved generating __config directives away

1152 fixes #1469504 and #1474602,
1153 (pCodeRegOptimizeRegUsage): fixed typo in comment

1157 * device/examples/main8051.c: deleted - it was removed from CVS

1370 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1372 * src/SDCCpeeph.c (initPeepHole): implemented RFE 1460196, when both

1376 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1378 * src/mcs51/gen.c (genCall): fixed bug 1457608
1380 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1382 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1385 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1387 * src/SDCCpeeph.c (operandsLiteral): new, added,

1398 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1399 implemented patch 1120823 Thanks to Willy De la Court (normal
1400 interrupts need an interrupt number now if they are made critical),
1401 and enabled nesting of critical functions though not for gbz80
1402 (genCritical, genEndCritical): added functions
1403 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1404 * src/z80/mappings.i: added "ei" to all mappings
1406 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1408 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1409 submitted by the Debian SDCC maintainer Aurelien Jarno:
1410 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1411 archive with gcc 4.1 on mips and wrote the patch"
1413 2006-03-16 Raphael Neider <rneider AT web.de>
1415 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1416 the left operand is shorter than the result (c* = lit-c* + int),
1418 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1421 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1423 * src/.version: increased version number to 2.5.5
1424 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1425 linking is done manually in pic16 port's _linkEdit,
1426 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1427 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1428 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1429 allocate asmop as AOP_ACC,
1430 (aopForRemat): added parameter 'bool result' in function declaration,
1431 (pic16_aopGet): return AOP_ACC when accessing WREG,
1432 (pic16_popGetTempReg): minor modification,
1433 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1434 'pic16_allocWithIdx',
1435 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1436 calling function in absolute addresses,
1437 (genAssign): take into account AOP_ACC asmop,
1438 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1441 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1443 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1444 call to allocReg, not by manually allocating a new one,
1445 (pic16_assignRegisters): now before going through the register
1446 allocating functions mark all registers as free. This eliminates some
1447 side effects resulting from peephole parser done earlier in the backbone
1449 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1451 * src/SDCCicode.c (geniCodeLogic),

1470 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1471 (aopForSym, aopOp): increment asmop.allocated if reused,
1472 (freeAsmop): decrement asmop.allocated and check for zero instead of
1474 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1475 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1476 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1499 2006-03-06 Borut Razem <borut.razem AT siol.net>
1501 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1502 made the linker quiet
1504 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1506 * src/pic16/gen.c (genPcall): fixed bug #1443644
1507 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1508 which dumps before the function entry point a data byte which represents
1509 the number of the local variables used by the specified function, added
1510 'xinst' for initial support for Extended Instruction Support,
1511 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1512 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1513 port->fun_prefix anymore (may change later),
1514 (genFunction, genEndFunction): do not store/restore local registers for
1515 _main (this should take care the --main-return command line option in
1517 (genOr): removed some legacy pic-port instructions,
1518 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1519 performing operations with SFR's causes data to be written more than
1520 once to each SFR. Perhaps SFRs should be handled in special cases...
1521 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1523 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1524 into account for stack starting position,
1525 (struct OPTIONS pic16_optionsTable): added command line argument
1526 --extended or -y for Extended Instruction Support,
1527 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1528 (deassignLRs): *** perhaps the most important change, old 'for' code
1529 (commented out for reference), didn't account for some registers which
1530 were left marked 'not free' after a pointer operation. The change
1531 reduces register usage a lot in some cases
1533 2006-03-04 Borut Razem <borut.razem AT siol.net>

3856 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3857 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3858 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3859 immedDom() returning wrong block; probably fixes bug #1160833)
3861 2005-03-20 Borut Razem <borut.razem AT siol.net>
3863 * support/scripts/inc2h.pl: WIN32 port
3865 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3867 * device/lib/makefile.in: added abs.c and labs.c
3869 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3871 * device/include/stdint.h: added
3872 * device/lib/abs.c: added
3873 * device/lib/labs.c: added
3874 * device/include/stdlib.h: added abs() and labs() prototypes
3875 * device/lib/libsdcc.lib: added abs and labs
3876 * device/include/float.h,
3877 * device/lib/_fsmul.c,
3878 * device/lib/printf_fast.c,
3879 * device/lib/printf_tiny.c: updated comments
3881 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3883 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3886 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3888 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3889 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3891 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3893 * device/lib/printf_large.c: removed inline assembly for portability and
3894 readability. Use printf_fast if speed or size are more important.
3895 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3896 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3898 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3900 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3901 prevent compiler warning
3903 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3905 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3906 moved to level 0 and declared as static. Also they are explicit
3907 placed in access bank. This was necessery because some times they
3908 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3909 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3910 optimizations. Currently only compare to unsigned char is implemented,
3911 * src/pic16/gen.c: added fReturnIdx array,
3912 * (struct resolvedIfx) is moved to gen.h and made public,
3913 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3914 * (aopForSym): added an optimization to directly store in stack of
3915 the operand of a SEND iCode,
3916 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3917 but as registers instead (AOP_REG) using the fReturnIdx array,
3918 * (pic16_freeAsmop): remove the freed register from the
3919 _G.sregsAlloc field,
3920 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3921 a compare of 'WREG',
3922 * (pic16_popGetTempRegCond): changed function prototype, now
3923 function takes also a bitVector argument v which holds the current
3924 set of registers that are allocated for stack access by aopForSym,
3925 registers allocated in aopForSym for accessing stack symbols are not
3926 any more part of the functions usedRegs field,
3927 * (genCall): some times aopOp is called for a stack variable to be
3928 send, aopForSym might perform the push, if this is true make sure
3929 that genCall doesn't push the variable twice by testing _G.resDirect,
3930 * (genFunction): changed testing for unspecified interrupt number
3931 from 256 to INTNO_UNSPEC,
3932 * modified selection scheme of frame pointer generation. Previously
3933 if function did use local registers a frame pointer was generated,
3934 now a frame pointer is generated only if function has arguments
3935 (that need PLUSW2 register access), or has stack arguments, or the
3936 compiler is not instructed to omit the frame pointer,
3937 * (genEndFunction): before restoring local registers that were saved
3938 in the function preamble, also restore the registers that *might*
3939 have been allocated for stack access,
3940 * (genRet): removed some old comments,
3941 * (genCmp, the active (RN's) version): added a call to the
3942 pic16_genCmp_special function to perform the compare with a more
3943 robust and optimized way,
3944 * (genInline): a feature has been added in inline code generation,
3945 which allows a wildcard variable substitution when writing inline
3946 assembly. Code is incomplete and experimental therefore undocumented,
3947 * (genCast): changed order of aopOp for result and right to allow
3948 aopForSym to directly load the result if possible,
3949 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3950 perform an optimized compare on some selected special occasions,
3951 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3952 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3953 generate an IVT any more,
3954 * src/pic16/main.c (pic16_optionsTable): added command line option
3956 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3957 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3959 * src/pic16/NOTES: Raphael Neider added in list of active developers
3960 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3961 jumptable_end to prevent bug #,
3962 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3963 inCond and outCond fields,
3964 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3965 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3966 turn off register spilling,
3967 * (packRegsForOneUse): synced with other ports' versions although it
3968 is not used currently,
3969 * (pic16_packRegisters): added an optimization while reading
3970 structure bitfields, some registers may be saved (malloc code is
3971 decreased by 80 bytes)
3973 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3975 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3976 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3977 this can be optimized more?
3979 2005-03-10 Raphael Neider <rneider AT web.de>
3981 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3982 genNearPointerGet): (hopefully) fixed access to bitfields via
3983 pointers (p->bitN = x; and x = p->bitN; failed)
3985 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4173 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4174 this might fix SIGSEGVs on MinGW...

4263 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4264 used uninitialized in some cases)

4266 copy the third byte from the int -- now assumes 0x80 (data memory)
4267 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4268 operands (genAddLit expects the iCode's operands to swapped as

4618 generated for switch statements. For now you need to set the
4619 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4620 Now 4 algorithms for mcs51 jumptable generation are used:
4621 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4653 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4655 * added libc directory. The current version of LibC contains string
4656 functions, ctype functions and macros and some functions of the
4657 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4658 be extensively tested in the future. Standard disclaimer here.
4659 Library is not automatically build yet. But one can build it by
4660 invoking 'make' inside the libc directory.

4671 * (pic16_storeForReturn): optimized return of 0,
4672 * (genCmp): experimental code for new genCmp which uses PIC18's
4673 special compare&skip instructions. Initial tests fail some times
4674 with variables grater than 1 byte in size, so new code is disabled,
4675 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4677 * (genCast): began a fix to optimize the casting of a bit to another
4678 bit, now assigning a bitfield to another bitfield will fail, sorry,

4686 * (isBankInstruction): modified to return 0 for no banking instruction,
4687 and 1 for banking instruction,
4688 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4689 caused stop processing pCodes after a inline assembly block,
4690 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4692 registers when it shouldn't,
4693 * src/pic16/ralloc.c (allocReg): add preliminary support for
4694 supporting a limited set of temporary registers,
4696 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4698 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4699 genDataPointerSet): ensure assignments always copy in MSB to LSB
4701 (loadRegFromAop): recognize CLRH optimization,
4702 (genFunction): optimize RECEIVE iCodes in reentrant functions
4704 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4706 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4715 * device/lib/_gptrget.c (_gptrget),
4716 * device/lib/_gptrgetc.c (_gptrgetc),
4717 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4718 instead of sjmp to ret
4719 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided

7704 loaded with the linker search paths (-L arguments) and the libraries
7705 to be linked with the current source (-l arguments). Changes
7706 currently will affect only the pic16 port.
7707 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7708 include path the port specific paths and port specific libraries,
7709 * gplink command now contains the $3 argument,
7710 * src/pic16/device.h,
7711 * src/pic16/device.c,: structure PIC_device is made public and

7727 Documenting changes from previous commits.
7728 * configure.in (version 1.56),
7729 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7730 when generating output files to configure the pic16 library,
7731 but now I've commented it out, since gputils aren't installed in the
7732 SF compile farm, so library won't compile
7734 * device/lib/Makefile.in (version 1.56): initially I've added in
7735 target 'all' the prerequestive 'model-pic16' so it compiled the
7736 pic16 library, but now I've commented it out for the same reasons
7738 * added targets 'model-pic16' and 'objects-pic16' to compile the
7740 * added target 'port-specific-objects-pic16' to handle the
7741 generated libraries and copy them into the build/ directory
7742 * added target 'clean-intermediate-pic16' to clean intermediate
7743 files into pic16 directory
7744 * in target 'installdirs' added line to create directory pic16 in
7745 the installation path

7748 added lines to copy all header files to installation path,
7749 * in target 'installdirs' added line create directory for pic16
7750 headers in the installation path

7766 option so that it actually works. Made it specific to the z80, since
7767 the gbz80 doesn't have these kinds of I/O ports.
7769 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7771 * device/include/z180.h,

7798 data are now emitted in sorted order to reduce section naming,
7799 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7800 weren't marked as being in the access bank,

7804 Added portion of GNU PIC Library under the directory
7805 device/include/pic16 and device/lib/pic16. These files
7806 contain the declarations of SFRs for the PIC18Fxx2 devices.
7807 The directory is initialized via configure from toplevel.

7838 to better keep the right margin. Changed some notes about
7839 maintainance of the ports in section 3.2.1 - is it OK like this?
7841 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7843 SDCC source changes:
7844 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7879 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7881 * src/pic16/peeph.def: all peepholes with movff are commented out,
7882 because there is a problem in the pcode peep optimizer,
7883 * src/pic16/ralloc.c: the register allocator can now reuse local

7993 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7995 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7996 (default behaviour).
7998 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8000 A python script to validate compiler diagnostic messages. It can be
8001 used to verify that sdcc complains about bad c source code and
8002 gives a good location of the error.
8003 * support/valdiag/Makefile,
8004 * support/valdiag/valdiag.py,
8005 * support/valdiag/tests/*

8022 Bug reported from Jesus Calvino-Fraga
8024 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8026 * sdcc.spec: updated
8027 * device/include/Makefile.in: don't install CVS directories
8028 * device/lib/Makefile.in: added removal of CVS directories after install
8029 * doc/Makefile: fixed install, added local_icons
8030 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8031 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8032 * src/ds390/gen.c (genRightShift): fixed bug #870788
8033 * src/SDCCast.c (decorateType): fixed bug #870781
8035 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8037 PIC16 port related changes:
8038 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8039 added variable stackPos,
8041 * gen.c: genCall, assignResultValue: added support for
8042 pushing/retrieving function parameters to/from stack,
8043 genFunction,genEndFunction: setup stack frame for the
8045 genAddrOf: will be changed according to bug 863624
8047 * added files genutils.c and genutils.h which contain gen*
8048 debugged and optimised functions extracted from gen.c
8050 * glue.c: added variable 'externs' which holds extern symbols,
8051 pic16emitRegularMap: is modified to properly handle relocatable
8052 symbols under the new scheme,
8053 pic16createInterruptVect: is modified
8054 pic16printPublics: is modified to emit 'global' assembler directives,
8055 added pic16_printExterns to print extern symbols,
8056 pic16glue: initializes stack/frame pointer in the beginning of
8057 the assembly output. Temporary hack, will be corrected later,
8058 because gplink yet does not support stack and SDCC does not
8059 yet support a type of crt0.o object to create the final binary.
8061 * Removed many lines that contain 8051 legacy code.
8062 * The code is finally placed under a 'code' directive.
8063 * Added port specific options.
8065 * _process_pragma: simplified since now we do not need *special*
8066 include file to define SFR registers. But a separate header
8067 will be needed. This will be developed later.
8068 * _pic16_parseOptions: added, parses port specific options:
8069 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8070 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8071 --preplace-udata-with=
8073 * _pic16_setDefaultOptions: modified to initialize section names,
8074 but hack is temporarly out of order since it needs improvement.
8075 * _pic16_genAssemblerPreamble: configuration words are emitted by
8076 their address instead of their name. This part is incomplete and
8077 supports only the 18Fxx2 devices. Other devices will emit an error
8078 during assembly since they do not contain the same set of config
8080 * _pic16_genIVT: is modified,
8082 * pcode.c: added definitions for some hardware registers that are needed
8084 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8085 All PCI entries are updated. Now LFSR is supported.
8086 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8087 * added pic16_newpCodeOpLit2 to support instructions with
8088 two literal arguments
8089 * pic16_pCode2str: corrected code that emits assembler instructions
8090 with two literal operands and those that have an access bit modifier
8091 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8092 this fixes a bug which caused some labels to be lost, when an
8093 assembler directive was added, i.e. banksel,
8094 * pic16_FixRegisterBanking: improved logic that causes the insertion
8096 * InlineFunction: functions that are called once, are not any more
8097 inlined. This can be a port option in the future,
8099 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8101 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8102 hold the corresponding uninitialized symbols,
8103 * pic16_allocProcessorRegister: registers have explicit marked the
8105 * pic16_allocInternalRegister: registers are explicit marked as
8107 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8108 processing list, so bit registers were lost,
8111 * ralloc.h: added field 'accessBank' and original symbol operand
8112 in register definition,
8113 * removed the field isMapped from register definition,
8115 ** Several functions have been removed from various sources:
8116 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8117 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8118 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8119 pic16_assignRelocatableRegisters
8121 ** others have been introduced:
8122 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8123 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8125 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8127 * support/scripts/inc2h.pl: changed definition of BIT_AT
8128 to emit 'sbit at' instead of 'bit at'. This was a request.
8130 PIC16 port related preliminary changes:
8131 * gen.c: prefixed function popRegFromString with
8132 pic16_ and all references to it corrected
8133 * pcode.c: all pic16_pc_* hardware registers prefixed
8134 with underscore (_),
8135 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8136 * ralloc.c: newReg(): when register is REG_SFR then
8137 set address to rIdx,
8138 pic16_allocProcessorRegister(): marks register wasUsed=0
8139 pic16_writeUsedRegs(): added a call to assign processor
8140 registers via pic16_assignFixedRegisters
8142 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8144 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8145 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8146 variables in unused register banks. Also the SSEG is placed
8147 wherever there is enough space for it, and IDATA can be anywhere
8148 in internal RAM. For now compile using -Wl-Y[stack_size].
8149 The mem file is different for this option as well, since it
8150 makes no sense of talking about DSEG lenght.
8152 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8154 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8155 in certain cases, e.g. when ROM assignment, patch provided
8156 from Albert den Haan.
8158 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8301 * src/mcs51/peephole.def,
8302 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9043 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9044 support for standard C idiom of memory mapped variables; for
9045 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9046 to xdata int at 0x1234 tempvar = 1.
9047 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9048 provided by Akiya ISHIDA

9064 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9066 Fixed bug #621531 (const & volatile confusion in the type chain).
9067 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9068 refer to the const or volatile state of the pointer itself.

9146 * src/mcs51/gen.c (leftRightUseAcc),
9147 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9148 iCode properly now. Use getSize instead of nRegs since a & b
9149 aren't part of the nRegs tally.
9151 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9153 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9154 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive

9157 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9159 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9160 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9161 fetching of the pointer
9162 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9163 copied from genNearPointerSet()
9164 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9165 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9166 If they pop r0/r1 they must be called in the opposite order than aopOp().
9167 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9168 (resp. --stack-auto), prepared for --xstack

9177 these ports have their own __sdcc_external_start()
9179 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9181 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9182 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9183 type for bits was changed. It resulted in bit variables becoming
9184 global, which is not permitted in PIC 14 assembly output.
9186 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9188 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9192 Z80 and MCS51 linkers complaint if a public symbol is defined
9193 in more than one library module:
9197 * as/mcs51/Makefile.in
9199 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9201 A few small changes that speed up the peephole optimizer.
9205 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9207 Try to make the peephole optimizer smarter by maintaining
9208 an association between the assembly source code and the
9209 iCodes that originated them. Put this information to use
9210 with a new peephole rule condition "notVolatile" so that
9211 the rules can be aggressive yet still safe.
9216 * src/mcs51/peeph.def
9218 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9222 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9223 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9224 if the left or right operand symbols have the accuse flag set.
9226 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9228 Changed the type of the result of the ! (NOT) operator to char;
9229 previously it returned the same type as the source. This allows
9230 us to eliminate all the genFloatNot functions (all of its target
9231 implementations were very buggy) since !float can use the same
9234 * src/SDCCicode.c (ast2iCode): ! returns char
9235 * src/mcs51/gen.c (genNot, genNotFloat),
9236 * src/ds390/gen.c (genNot, genNotFloat),
9237 * src/z80/gen.c (genNot, genNotFloat),
9238 * src/pic/gen.c (genNot, genNotFloat),
9239 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9241 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9243 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9244 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9245 during interrupts. Ensure WSAVE is located at a shared bank address.
9246 2. Fixed page selection in some places
9247 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9248 the registers name strings.
9249 4. Fixed "signed / unsigned compare" compiler warnings.
9250 5. The PIC port manages its own allocation of the general purpose
9251 registers, but makes no attempt to reuse them. As a result when
9252 compiling it soon runs out of general purpose registers. Some
9253 additional code was added to the files pcode.c and device.c to walk
9254 through the function call tree and rename the registers so that they
9264 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9265 genPlus() & genMinus() when the result is the same as left or right
9267 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9269 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
9271 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9273 Made bitfield a distinct type from bit so that bitfields
9274 convert as per ANSI C and bits retain their traditional
9275 boolean style behaviour. Implemented bitfield support in
9283 * src/ds390/gen.c: bit v bitfield split
9284 * src/z80/gen.c: New support for bitfields
9285 * support/regression/tests/bitfields.c: reenabled z80,
9288 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9290 Rules 246.x, 247.x relate to bitfields, the others speed up
9291 access to xdata mapped I/O devices.
9293 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9295 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9297 Cleaned up genPackBits and genUnpackBits and added two helper
9298 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9299 for literal assignments in genPackBits (thanks to Frieder for
9305 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9307 Fixed bug #748310 (pointer to function type mishandled when the
9308 function name is omitted). Also fixed a SIGSEGV when a function
9309 attribute (reentrant, etc) is used on a non-function or on a
9310 function but misplaced before the parameter list.
9312 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9314 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9315 * support/Util/SDCCerr.h,
9316 * support/Util/SDCCerr.c: Added func attr misuse error msg
9318 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9320 Fixed bug #787649 by anonymous
9321 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9322 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9324 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9326 Fixed numerous bitfield problems.
9328 * src/SDCC.y: More bitfield related error checking
9330 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
9331 * support/Util/SDCCerr.h,
9332 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
9333 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
9334 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
9335 * support/regression/tests/bitfields.c: tests added
9337 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9339 Made the constant following the "interrupt" keyword optional. If
9340 omitted, the function will not automatically be given an entry
9341 in the interrupt vector table (similar to #pragma NOIV, but
9342 less syntacticly kludgy). The interrupt number is also now
9343 range checked. Also fixed a bug in the high order bit example

9872 * src/SDCCmain.c: linkOptions is changed to set *,
9873 added if/endif conditional macros to remove options help
9874 messages from optionsTable when a port is not configured, added
9875 support for the PIc16 port in the ports table, when executing
9876 the compiler with no port specified on command line, a default
9877 port is selected with the new macro DEFAULT_PORT which is
9878 defined in port.h, in setDefaultOptions() linkOptions is removed
9879 from initialization assignment, since now it is a set,
9880 parseCmdLine uses setParseWithComma for linkOptions, in
9881 linkEdit() linkOptions are accessed with new function indexSet()
9882 which returns the i'th item of a set variable. See SDCCset.c, in
9883 linkEdit() when calling buildCmdLine(), added linkOptions as
9884 last argument. Now users can pass arguments to gplink via the
9885 -Wl option, main() uses pic16glue() to glue up pic16 programs

9899 gpasm complaining and test the linkage with gplink, _linkCmd and
9900 _asmCmd changed to be more gplink and gpasm friendly
9901 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9902 produced an error when parsed, peep rule 12 is added to utilize
9903 movff, but it is commented out since the pCode does not support
9904 yet a command with 2 address arguments

10956 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10957 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10963 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10964 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10966 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10967 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10969 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10971 * in /sdcc/as/mcs51/ changed these files in order to create an
10972 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10973 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10974 following files to include the previous two files: aslink.dsp,
10975 Makefile.aslink, Makefile.bcc, and Makefile.in.
10977 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10978 .adb instead of .cdb
10980 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10982 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10983 value from option --iram-size.
10985 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10987 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10990 2002-09-18 <wiml AT hhhh.org>
10992 * SDCClrange.h: exposed setFromRange() and setToRange()
10993 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10994 packRegsForAccUse() (bug 542397)
10995 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10996 multiple times and emitting the fetch operations more than once
10997 added aopGetUsesAcc() function to allow binary operators to
10998 fetch their operands in the correct order; made genMinus() emit
10999 compact code for X = LITERAL - Y
11001 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11002 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11003 sprintf() in line 1267.
11005 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11006 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11009 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11010 Changes to aslink (All the changes are marked with 'JCF'):
11012 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11015 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11016 area BSEG. Also moves, if possible, the DATA area down into the internal
11017 ram so more space is available.
11019 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11022 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11023 not bytes. Function summary() which creates a memory usage summary
11024 file with extension .mem. Reports of overlaping stack and small stack
11025 size. If the space for the stack is less than 16 bytes aslink trows a
11028 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11029 the 8051. Option 'y' for memory summary output file.
11031 Changes to sdcc (All the changes are marked with 'JCF'):
11033 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11035 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11036 overlaying area for it (uses RegBankUsed[4]).
11038 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11039 bank zero as used by default. By default aslink locates the stack
11040 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11041 the creation of the .mem file. Delegates the allocation of data area
11042 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11043 the begining of the stack area to aslink.
11045 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11046 glue() in SDCCglue.c creates an area for it.
11048 2002-09-03 Borut Razem <borut.razem AT siol.net>
11049 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11050 sdcc/src/pic/glue.c:
11051 introduced atexit() handler for teporay files removal in case of
11052 errors, assertions, ...
11054 2002-08-29 Borut Razem <borut.razem AT siol.net>
11055 * sdcc/support/cpp2/auto-host_vc_in.h:
11056 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11057 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11058 Maybe there is a similar problem with BORLANDC? It should be checked!
11060 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11061 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11062 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11063 was not executed, and the compiler (cl) launched a warning:
11064 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11066 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11067 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11069 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11070 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11072 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11073 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11074 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11075 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11076 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11077 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11078 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11079 - added Release configuration in VS projects
11080 - review of compiler an linker options
11081 - VC .exe files are generated in bin_vc directory, not to interfere
11082 with binaries generated from other projects (cygwin, mingw, bcc ...)
11084 * sdcc/src/yacc.dsp: added
11086 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11087 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11088 and insert the version number definitions from .version
11090 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11092 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11093 added - genarate auto-host.h using auto-host_vc_in.h as template
11096 removed from CVS, generated automatically
11098 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11099 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11101 2002-08-11 Borut Razem <borut.razem AT siol.net>
11102 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11104 2002-08-10 Borut Razem <borut.razem AT siol.net>
11105 * src/SDCCmain.c (main):
11106 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11107 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11108 The consequence was that some temporary files were not removed.
11111 unification of code in functions tempfilename() and tempfile():
11112 function tempnam() is defined in Visual Studio 6.0 and .NET
11114 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11116 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11117 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11118 - removed compiler command line option /WX: Treats all warnings as errors
11119 - update a list of source files, included into the project
11121 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11122 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11123 changed project type to Generic Project so that can be correcly converted to VS.NET project
11125 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11127 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11129 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11131 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11132 added return 0 statements after assert() to make compiler happy
11134 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11135 added newline in the def file to keep MSC compiler satisfied
11137 * sdcc/src/z80/gen.c:
11138 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11139 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11140 - solved MSC error in function aopDump()
11142 * sdcc_vc.h: define PREFIX as "\\sdcc"
11144 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11145 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11147 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11148 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11149 - Rewrote the register banking algorithm.
11150 - Added pCode live-range analysis to registers (for now, only non-used and
11151 singly-used registers optimized away)
11153 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11155 * 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.
11157 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11158 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
11160 2002-04-22 Michael Hope <michaelh AT vroom>
