1117 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1119 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1120 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1122 One basic decision: e.g. src/clean.mk includes further files. In order
1123 to make this work there are two solutions:
1124 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1125 run configure on them. This way they can use
1126 'include $(srcdir)/port-clean.mk'
1127 - always include clean.mk by the Makefile at the same level. To avoid
1128 that `make clean` tries to include and build Makefile.dep the
1129 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1130 implemented, because now even `make uninstall` doesn't create
1131 Makefile.in. clean.mk could be eliminated by pasting it in
1134 * debugger/mcs51/Makefile.in: build own objects from library sources
1135 (SLIB, SDCC) in current directory
1137 * configure, configure.in: renamed --disable-device-lib-build in
1138 --disable-device-lib; added --enable-doc, the required tools are
1139 searched by configure; added result message; the toolchain for the
1140 belonging ports are now only built, if the port is enabled.
1142 * support/regression/*: all output is written in directory gen, because
1143 the fwk and ports directories don't livet in the build tree using vpath
1145 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1146 --disable-device-lib, added --enable-doc, added section VPATH
1148 * sim/ucsim/configure.in,
1149 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1150 z80 are enabled by default
1152 2006-04-24 Raphael Neider <rneider AT web.de>
1154 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1155 to config word, "pic14_"-prefixed some extern functions
1156 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1157 config word has been found
1158 * src/pic/device.h: added prototypes
1159 * src/pic/pcode.c: added "pic14_"-prefix where needed
1160 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1162 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1176 fixes #1469504 and #1474602,
1177 (pCodeRegOptimizeRegUsage): fixed typo in comment

1181 * device/examples/main8051.c: deleted - it was removed from CVS

1400 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1402 * src/mcs51/gen.c (genCall): fixed bug 1457608
1404 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1409 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1411 * src/SDCCpeeph.c (operandsLiteral): new, added,

1423 implemented patch 1120823 Thanks to Willy De la Court (normal
1424 interrupts need an interrupt number now if they are made critical),
1425 and enabled nesting of critical functions though not for gbz80
1426 (genCritical, genEndCritical): added functions
1427 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1428 * src/z80/mappings.i: added "ei" to all mappings

1433 submitted by the Debian SDCC maintainer Aurelien Jarno:
1434 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1435 archive with gcc 4.1 on mips and wrote the patch"
1437 2006-03-16 Raphael Neider <rneider AT web.de>
1439 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1440 the left operand is shorter than the result (c* = lit-c* + int),
1442 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1445 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1447 * src/.version: increased version number to 2.5.5
1448 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1449 linking is done manually in pic16 port's _linkEdit,
1450 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1451 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1452 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1453 allocate asmop as AOP_ACC,
1454 (aopForRemat): added parameter 'bool result' in function declaration,
1455 (pic16_aopGet): return AOP_ACC when accessing WREG,
1456 (pic16_popGetTempReg): minor modification,
1457 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1458 'pic16_allocWithIdx',
1459 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1460 calling function in absolute addresses,
1461 (genAssign): take into account AOP_ACC asmop,
1462 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1465 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1467 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1468 call to allocReg, not by manually allocating a new one,
1469 (pic16_assignRegisters): now before going through the register
1470 allocating functions mark all registers as free. This eliminates some
1471 side effects resulting from peephole parser done earlier in the backbone
1473 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1475 * src/SDCCicode.c (geniCodeLogic),

1494 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1495 (aopForSym, aopOp): increment asmop.allocated if reused,
1496 (freeAsmop): decrement asmop.allocated and check for zero instead of
1498 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1499 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1500 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1523 2006-03-06 Borut Razem <borut.razem AT siol.net>
1525 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1526 made the linker quiet
1528 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1530 * src/pic16/gen.c (genPcall): fixed bug #1443644
1531 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1532 which dumps before the function entry point a data byte which represents
1533 the number of the local variables used by the specified function, added
1534 'xinst' for initial support for Extended Instruction Support,
1535 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1536 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1537 port->fun_prefix anymore (may change later),
1538 (genFunction, genEndFunction): do not store/restore local registers for
1539 _main (this should take care the --main-return command line option in
1541 (genOr): removed some legacy pic-port instructions,
1542 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1543 performing operations with SFR's causes data to be written more than
1544 once to each SFR. Perhaps SFRs should be handled in special cases...
1545 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1547 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1548 into account for stack starting position,
1549 (struct OPTIONS pic16_optionsTable): added command line argument
1550 --extended or -y for Extended Instruction Support,
1551 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1552 (deassignLRs): *** perhaps the most important change, old 'for' code
1553 (commented out for reference), didn't account for some registers which
1554 were left marked 'not free' after a pointer operation. The change
1555 reduces register usage a lot in some cases
1557 2006-03-04 Borut Razem <borut.razem AT siol.net>
1559 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3849 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3852 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3854 * src/port.h (struct PORT),

3880 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3881 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3882 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3883 immedDom() returning wrong block; probably fixes bug #1160833)
3885 2005-03-20 Borut Razem <borut.razem AT siol.net>
3887 * support/scripts/inc2h.pl: WIN32 port
3889 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3891 * device/lib/makefile.in: added abs.c and labs.c
3893 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3895 * device/include/stdint.h: added
3896 * device/lib/abs.c: added
3897 * device/lib/labs.c: added
3898 * device/include/stdlib.h: added abs() and labs() prototypes
3899 * device/lib/libsdcc.lib: added abs and labs
3900 * device/include/float.h,
3901 * device/lib/_fsmul.c,
3902 * device/lib/printf_fast.c,

3905 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3907 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3910 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3912 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3913 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3915 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3917 * device/lib/printf_large.c: removed inline assembly for portability and
3918 readability. Use printf_fast if speed or size are more important.
3919 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3920 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3922 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3924 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3925 prevent compiler warning
3927 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3929 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3930 moved to level 0 and declared as static. Also they are explicit
3931 placed in access bank. This was necessery because some times they
3932 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3933 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3934 optimizations. Currently only compare to unsigned char is implemented,
3935 * src/pic16/gen.c: added fReturnIdx array,
3936 * (struct resolvedIfx) is moved to gen.h and made public,
3937 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3938 * (aopForSym): added an optimization to directly store in stack of
3939 the operand of a SEND iCode,
3940 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3941 but as registers instead (AOP_REG) using the fReturnIdx array,
3942 * (pic16_freeAsmop): remove the freed register from the
3943 _G.sregsAlloc field,
3944 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3945 a compare of 'WREG',
3946 * (pic16_popGetTempRegCond): changed function prototype, now
3947 function takes also a bitVector argument v which holds the current
3948 set of registers that are allocated for stack access by aopForSym,
3949 registers allocated in aopForSym for accessing stack symbols are not
3950 any more part of the functions usedRegs field,
3951 * (genCall): some times aopOp is called for a stack variable to be
3952 send, aopForSym might perform the push, if this is true make sure
3953 that genCall doesn't push the variable twice by testing _G.resDirect,
3954 * (genFunction): changed testing for unspecified interrupt number
3955 from 256 to INTNO_UNSPEC,
3956 * modified selection scheme of frame pointer generation. Previously
3957 if function did use local registers a frame pointer was generated,
3958 now a frame pointer is generated only if function has arguments
3959 (that need PLUSW2 register access), or has stack arguments, or the
3960 compiler is not instructed to omit the frame pointer,
3961 * (genEndFunction): before restoring local registers that were saved
3962 in the function preamble, also restore the registers that *might*
3963 have been allocated for stack access,
3964 * (genRet): removed some old comments,
3965 * (genCmp, the active (RN's) version): added a call to the
3966 pic16_genCmp_special function to perform the compare with a more
3967 robust and optimized way,
3968 * (genInline): a feature has been added in inline code generation,
3969 which allows a wildcard variable substitution when writing inline
3970 assembly. Code is incomplete and experimental therefore undocumented,
3971 * (genCast): changed order of aopOp for result and right to allow
3972 aopForSym to directly load the result if possible,
3973 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3974 perform an optimized compare on some selected special occasions,
3975 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3976 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3977 generate an IVT any more,
3978 * src/pic16/main.c (pic16_optionsTable): added command line option
3980 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3981 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3983 * src/pic16/NOTES: Raphael Neider added in list of active developers
3984 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3985 jumptable_end to prevent bug #,
3986 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3987 inCond and outCond fields,
3988 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3989 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3990 turn off register spilling,
3991 * (packRegsForOneUse): synced with other ports' versions although it
3992 is not used currently,
3993 * (pic16_packRegisters): added an optimization while reading
3994 structure bitfields, some registers may be saved (malloc code is
3995 decreased by 80 bytes)
3997 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3999 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4000 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4001 this can be optimized more?
4003 2005-03-10 Raphael Neider <rneider AT web.de>
4005 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4006 genNearPointerGet): (hopefully) fixed access to bitfields via
4007 pointers (p->bitN = x; and x = p->bitN; failed)
4009 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4050 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4052 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4053 to keep the correct label reference count when adding/removing references
4054 to labels. A peephole file using this is appended to patch #1144962.

4196 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4197 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4198 this might fix SIGSEGVs on MinGW...
4199 * src/SDCCopt.c (killDeadCode): restored original behaviour
4200 (volatile operands might get thrown away though)
4202 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4286 * (genUminus): rewritten to for efficiency
4287 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4288 used uninitialized in some cases)

4290 copy the third byte from the int -- now assumes 0x80 (data memory)
4291 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4292 operands (genAddLit expects the iCode's operands to swapped as
4293 well), fixed leftover bytes (crashed for short left operands)

4642 generated for switch statements. For now you need to set the
4643 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4644 Now 4 algorithms for mcs51 jumptable generation are used:
4645 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4679 * added libc directory. The current version of LibC contains string
4680 functions, ctype functions and macros and some functions of the
4681 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4682 be extensively tested in the future. Standard disclaimer here.
4683 Library is not automatically build yet. But one can build it by

4695 * (pic16_storeForReturn): optimized return of 0,
4696 * (genCmp): experimental code for new genCmp which uses PIC18's
4697 special compare&skip instructions. Initial tests fail some times
4698 with variables grater than 1 byte in size, so new code is disabled,
4699 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4701 * (genCast): began a fix to optimize the casting of a bit to another
4702 bit, now assigning a bitfield to another bitfield will fail, sorry,

4710 * (isBankInstruction): modified to return 0 for no banking instruction,
4711 and 1 for banking instruction,
4712 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4713 caused stop processing pCodes after a inline assembly block,
4714 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4716 registers when it shouldn't,
4717 * src/pic16/ralloc.c (allocReg): add preliminary support for
4718 supporting a limited set of temporary registers,

7725 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7727 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7728 loaded with the linker search paths (-L arguments) and the libraries
7729 to be linked with the current source (-l arguments). Changes
7730 currently will affect only the pic16 port.
7731 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7732 include path the port specific paths and port specific libraries,
7733 * gplink command now contains the $3 argument,
7734 * src/pic16/device.h,
7735 * src/pic16/device.c,: structure PIC_device is made public and
7736 renamed to PIC16_device, the same for variable Pics which is renamed

7751 Documenting changes from previous commits.
7752 * configure.in (version 1.56),
7753 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7754 when generating output files to configure the pic16 library,
7755 but now I've commented it out, since gputils aren't installed in the
7756 SF compile farm, so library won't compile
7758 * device/lib/Makefile.in (version 1.56): initially I've added in
7759 target 'all' the prerequestive 'model-pic16' so it compiled the
7760 pic16 library, but now I've commented it out for the same reasons
7762 * added targets 'model-pic16' and 'objects-pic16' to compile the
7764 * added target 'port-specific-objects-pic16' to handle the
7765 generated libraries and copy them into the build/ directory
7766 * added target 'clean-intermediate-pic16' to clean intermediate
7767 files into pic16 directory
7768 * in target 'installdirs' added line to create directory pic16 in
7769 the installation path
7771 * device/include/Makefile.in (version 1.11): in target 'install'
7772 added lines to copy all header files to installation path,
7773 * in target 'installdirs' added line create directory for pic16
7774 headers in the installation path

7789 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7790 option so that it actually works. Made it specific to the z80, since
7791 the gbz80 doesn't have these kinds of I/O ports.
7793 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7795 * device/include/z180.h,

7819 via literal number. The symbol is placed in the corresponding
7820 position of the data ram
7821 * (pic16_dump_section): relocatable and absolute uninitialized
7822 data are now emitted in sorted order to reduce section naming,
7823 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7824 weren't marked as being in the access bank,
7826 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7828 Added portion of GNU PIC Library under the directory
7829 device/include/pic16 and device/lib/pic16. These files
7830 contain the declarations of SFRs for the PIC18Fxx2 devices.
7831 The directory is initialized via configure from toplevel.

7861 all over. Telling LaTeX to be less strict with word spacing
7862 to better keep the right margin. Changed some notes about
7863 maintainance of the ports in section 3.2.1 - is it OK like this?
7865 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8017 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8019 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8020 (default behaviour).
8022 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8024 A python script to validate compiler diagnostic messages. It can be
8025 used to verify that sdcc complains about bad c source code and
8026 gives a good location of the error.
8027 * support/valdiag/Makefile,
8028 * support/valdiag/valdiag.py,
8029 * support/valdiag/tests/*

8046 Bug reported from Jesus Calvino-Fraga
8048 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8050 * sdcc.spec: updated
8051 * device/include/Makefile.in: don't install CVS directories
8052 * device/lib/Makefile.in: added removal of CVS directories after install
8053 * doc/Makefile: fixed install, added local_icons
8054 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8055 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8056 * src/ds390/gen.c (genRightShift): fixed bug #870788
8057 * src/SDCCast.c (decorateType): fixed bug #870781
8059 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8061 PIC16 port related changes:
8062 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8063 added variable stackPos,
8065 * gen.c: genCall, assignResultValue: added support for
8066 pushing/retrieving function parameters to/from stack,
8067 genFunction,genEndFunction: setup stack frame for the
8069 genAddrOf: will be changed according to bug 863624
8071 * added files genutils.c and genutils.h which contain gen*
8072 debugged and optimised functions extracted from gen.c
8074 * glue.c: added variable 'externs' which holds extern symbols,
8075 pic16emitRegularMap: is modified to properly handle relocatable
8076 symbols under the new scheme,
8077 pic16createInterruptVect: is modified
8078 pic16printPublics: is modified to emit 'global' assembler directives,
8079 added pic16_printExterns to print extern symbols,
8080 pic16glue: initializes stack/frame pointer in the beginning of
8081 the assembly output. Temporary hack, will be corrected later,
8082 because gplink yet does not support stack and SDCC does not
8083 yet support a type of crt0.o object to create the final binary.
8085 * Removed many lines that contain 8051 legacy code.
8086 * The code is finally placed under a 'code' directive.
8087 * Added port specific options.
8089 * _process_pragma: simplified since now we do not need *special*
8090 include file to define SFR registers. But a separate header
8091 will be needed. This will be developed later.
8092 * _pic16_parseOptions: added, parses port specific options:
8093 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8094 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8095 --preplace-udata-with=
8097 * _pic16_setDefaultOptions: modified to initialize section names,
8098 but hack is temporarly out of order since it needs improvement.
8099 * _pic16_genAssemblerPreamble: configuration words are emitted by
8100 their address instead of their name. This part is incomplete and
8101 supports only the 18Fxx2 devices. Other devices will emit an error
8102 during assembly since they do not contain the same set of config
8104 * _pic16_genIVT: is modified,
8106 * pcode.c: added definitions for some hardware registers that are needed
8108 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8109 All PCI entries are updated. Now LFSR is supported.
8110 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8111 * added pic16_newpCodeOpLit2 to support instructions with
8112 two literal arguments
8113 * pic16_pCode2str: corrected code that emits assembler instructions
8114 with two literal operands and those that have an access bit modifier
8115 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8116 this fixes a bug which caused some labels to be lost, when an
8117 assembler directive was added, i.e. banksel,
8118 * pic16_FixRegisterBanking: improved logic that causes the insertion
8120 * InlineFunction: functions that are called once, are not any more
8121 inlined. This can be a port option in the future,
8123 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8125 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8126 hold the corresponding uninitialized symbols,
8127 * pic16_allocProcessorRegister: registers have explicit marked the
8129 * pic16_allocInternalRegister: registers are explicit marked as
8131 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8132 processing list, so bit registers were lost,
8135 * ralloc.h: added field 'accessBank' and original symbol operand
8136 in register definition,
8137 * removed the field isMapped from register definition,
8139 ** Several functions have been removed from various sources:
8140 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8141 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8142 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8143 pic16_assignRelocatableRegisters
8145 ** others have been introduced:
8146 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8147 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8149 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8151 * support/scripts/inc2h.pl: changed definition of BIT_AT
8152 to emit 'sbit at' instead of 'bit at'. This was a request.
8154 PIC16 port related preliminary changes:
8155 * gen.c: prefixed function popRegFromString with
8156 pic16_ and all references to it corrected
8157 * pcode.c: all pic16_pc_* hardware registers prefixed
8158 with underscore (_),
8159 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8160 * ralloc.c: newReg(): when register is REG_SFR then
8161 set address to rIdx,
8162 pic16_allocProcessorRegister(): marks register wasUsed=0
8163 pic16_writeUsedRegs(): added a call to assign processor
8164 registers via pic16_assignFixedRegisters
8166 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8168 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8169 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8170 variables in unused register banks. Also the SSEG is placed
8171 wherever there is enough space for it, and IDATA can be anywhere
8172 in internal RAM. For now compile using -Wl-Y[stack_size].
8173 The mem file is different for this option as well, since it
8174 makes no sense of talking about DSEG lenght.
8176 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8178 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8179 in certain cases, e.g. when ROM assignment, patch provided
8180 from Albert den Haan.
8182 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8324 SDCC_NOGENRAMCLEAR to disable this.
8325 * src/mcs51/peephole.def,
8326 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8327 (allows non-interrupt and interrupt code to safely compete for a resource
8328 without the non-interrupt code having to disable interrupts)
8330 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8332 * src/SDCCicode.c (geniCodeAdd),

8347 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8349 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.

8352 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8354 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

8425 it breaks with bitfields, extern declarations, and gcse analysis.
8426 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8427 could be assigned through a pointer, so don't complain.

9205 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9206 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9207 type for bits was changed. It resulted in bit variables becoming

9225 A few small changes that speed up the peephole optimizer.
9229 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9231 Try to make the peephole optimizer smarter by maintaining
9232 an association between the assembly source code and the
9233 iCodes that originated them. Put this information to use
9234 with a new peephole rule condition "notVolatile" so that
9235 the rules can be aggressive yet still safe.
9240 * src/mcs51/peeph.def
9242 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9246 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9247 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9248 if the left or right operand symbols have the accuse flag set.
9250 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9252 Changed the type of the result of the ! (NOT) operator to char;
9253 previously it returned the same type as the source. This allows
9254 us to eliminate all the genFloatNot functions (all of its target
9255 implementations were very buggy) since !float can use the same
9258 * src/SDCCicode.c (ast2iCode): ! returns char

9267 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9268 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9269 during interrupts. Ensure WSAVE is located at a shared bank address.
9270 2. Fixed page selection in some places
9271 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9272 the registers name strings.
9273 4. Fixed "signed / unsigned compare" compiler warnings.
9274 5. The PIC port manages its own allocation of the general purpose
9275 registers, but makes no attempt to reuse them. As a result when
9276 compiling it soon runs out of general purpose registers. Some
9277 additional code was added to the files pcode.c and device.c to walk
9278 through the function call tree and rename the registers so that they
9288 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9289 genPlus() & genMinus() when the result is the same as left or right

9295 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9297 Made bitfield a distinct type from bit so that bitfields
9298 convert as per ANSI C and bits retain their traditional
9299 boolean style behaviour. Implemented bitfield support in
9307 * src/ds390/gen.c: bit v bitfield split
9308 * src/z80/gen.c: New support for bitfields
9309 * support/regression/tests/bitfields.c: reenabled z80,
9312 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9314 Rules 246.x, 247.x relate to bitfields, the others speed up
9315 access to xdata mapped I/O devices.
9317 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9319 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9321 Cleaned up genPackBits and genUnpackBits and added two helper
9322 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9323 for literal assignments in genPackBits (thanks to Frieder for
9329 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9331 Fixed bug #748310 (pointer to function type mishandled when the
9332 function name is omitted). Also fixed a SIGSEGV when a function
9333 attribute (reentrant, etc) is used on a non-function or on a
9334 function but misplaced before the parameter list.
9336 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9338 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9339 * support/Util/SDCCerr.h,

9363 Made the constant following the "interrupt" keyword optional. If
9364 omitted, the function will not automatically be given an entry
9365 in the interrupt vector table (similar to #pragma NOIV, but
9366 less syntacticly kludgy). The interrupt number is also now
9367 range checked. Also fixed a bug in the high order bit example
9374 * support/Util/SDCCerr.c
9375 * support/Util/SDCCerr.h

9897 added if/endif conditional macros to remove options help
9898 messages from optionsTable when a port is not configured, added
9899 support for the PIc16 port in the ports table, when executing
9900 the compiler with no port specified on command line, a default
9901 port is selected with the new macro DEFAULT_PORT which is
9902 defined in port.h, in setDefaultOptions() linkOptions is removed
9903 from initialization assignment, since now it is a set,
9904 parseCmdLine uses setParseWithComma for linkOptions, in
9905 linkEdit() linkOptions are accessed with new function indexSet()
9906 which returns the i'th item of a set variable. See SDCCset.c, in
9907 linkEdit() when calling buildCmdLine(), added linkOptions as

10980 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10981 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10990 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10991 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10993 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10995 * in /sdcc/as/mcs51/ changed these files in order to create an
10996 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10997 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10998 following files to include the previous two files: aslink.dsp,
10999 Makefile.aslink, Makefile.bcc, and Makefile.in.
11001 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11002 .adb instead of .cdb
11004 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11006 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11007 value from option --iram-size.
11009 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11011 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11014 2002-09-18 <wiml AT hhhh.org>
11016 * SDCClrange.h: exposed setFromRange() and setToRange()
11017 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11018 packRegsForAccUse() (bug 542397)
11019 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11020 multiple times and emitting the fetch operations more than once
11021 added aopGetUsesAcc() function to allow binary operators to
11022 fetch their operands in the correct order; made genMinus() emit
11023 compact code for X = LITERAL - Y
11025 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11026 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11027 sprintf() in line 1267.
11029 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11030 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11033 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11034 Changes to aslink (All the changes are marked with 'JCF'):
11036 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11039 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11040 area BSEG. Also moves, if possible, the DATA area down into the internal
11041 ram so more space is available.
11043 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11046 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11047 not bytes. Function summary() which creates a memory usage summary
11048 file with extension .mem. Reports of overlaping stack and small stack
11049 size. If the space for the stack is less than 16 bytes aslink trows a
11052 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11053 the 8051. Option 'y' for memory summary output file.
11055 Changes to sdcc (All the changes are marked with 'JCF'):
11057 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11059 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11060 overlaying area for it (uses RegBankUsed[4]).
11062 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11063 bank zero as used by default. By default aslink locates the stack
11064 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11065 the creation of the .mem file. Delegates the allocation of data area
11066 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11067 the begining of the stack area to aslink.
11069 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11070 glue() in SDCCglue.c creates an area for it.
11072 2002-09-03 Borut Razem <borut.razem AT siol.net>
11073 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11074 sdcc/src/pic/glue.c:
11075 introduced atexit() handler for teporay files removal in case of
11076 errors, assertions, ...
11078 2002-08-29 Borut Razem <borut.razem AT siol.net>
11079 * sdcc/support/cpp2/auto-host_vc_in.h:
11080 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11081 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11082 Maybe there is a similar problem with BORLANDC? It should be checked!
11084 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11085 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11086 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11087 was not executed, and the compiler (cl) launched a warning:
11088 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11090 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11091 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11093 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11094 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11096 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11097 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11098 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11099 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11100 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11101 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11102 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11103 - added Release configuration in VS projects
11104 - review of compiler an linker options
11105 - VC .exe files are generated in bin_vc directory, not to interfere
11106 with binaries generated from other projects (cygwin, mingw, bcc ...)
11108 * sdcc/src/yacc.dsp: added
11110 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11111 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11112 and insert the version number definitions from .version
11114 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11116 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11117 added - genarate auto-host.h using auto-host_vc_in.h as template
11120 removed from CVS, generated automatically
11122 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11123 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11125 2002-08-11 Borut Razem <borut.razem AT siol.net>
11126 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11128 2002-08-10 Borut Razem <borut.razem AT siol.net>
11129 * src/SDCCmain.c (main):
11130 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11131 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11132 The consequence was that some temporary files were not removed.
11135 unification of code in functions tempfilename() and tempfile():
11136 function tempnam() is defined in Visual Studio 6.0 and .NET
11138 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11140 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11141 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11142 - removed compiler command line option /WX: Treats all warnings as errors
11143 - update a list of source files, included into the project
11145 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11146 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11147 changed project type to Generic Project so that can be correcly converted to VS.NET project
11149 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11151 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11153 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11155 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11156 added return 0 statements after assert() to make compiler happy
11158 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11159 added newline in the def file to keep MSC compiler satisfied
11161 * sdcc/src/z80/gen.c:
11162 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
