1488 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1490 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1491 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1493 One basic decision: e.g. src/clean.mk includes further files. In order
1494 to make this work there are two solutions:
1495 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1496 run configure on them. This way they can use
1497 'include $(srcdir)/port-clean.mk'
1498 - always include clean.mk by the Makefile at the same level. To avoid
1499 that `make clean` tries to include and build Makefile.dep the
1500 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1501 implemented, because now even `make uninstall` doesn't create
1502 Makefile.in. clean.mk could be eliminated by pasting it in
1505 * debugger/mcs51/Makefile.in: build own objects from library sources
1506 (SLIB, SDCC) in current directory
1508 * configure, configure.in: renamed --disable-device-lib-build in
1509 --disable-device-lib; added --enable-doc, the required tools are
1510 searched by configure; added result message; the toolchain for the
1511 belonging ports are now only built, if the port is enabled.
1513 * support/regression/*: all output is written in directory gen, because
1514 the fwk and ports directories don't livet in the build tree using vpath
1516 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1517 --disable-device-lib, added --enable-doc, added section VPATH
1519 * sim/ucsim/configure.in,
1520 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1521 z80 are enabled by default
1523 2006-04-24 Raphael Neider <rneider AT web.de>
1525 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1526 to config word, "pic14_"-prefixed some extern functions
1527 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1528 config word has been found
1529 * src/pic/device.h: added prototypes
1530 * src/pic/pcode.c: added "pic14_"-prefix where needed

1791 2006-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1793 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1794 implemented patch 1120823 Thanks to Willy De la Court (normal
1795 interrupts need an interrupt number now if they are made critical),
1796 and enabled nesting of critical functions though not for gbz80
1797 (genCritical, genEndCritical): added functions
1798 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1799 * src/z80/mappings.i: added "ei" to all mappings
1801 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1803 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1804 submitted by the Debian SDCC maintainer Aurelien Jarno:
1805 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1806 archive with gcc 4.1 on mips and wrote the patch"
1808 2006-03-16 Raphael Neider <rneider AT web.de>
1810 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1811 the left operand is shorter than the result (c* = lit-c* + int),
1813 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1816 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1818 * src/.version: increased version number to 2.5.5
1819 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1820 linking is done manually in pic16 port's _linkEdit,
1821 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1822 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1823 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1824 allocate asmop as AOP_ACC,
1825 (aopForRemat): added parameter 'bool result' in function declaration,
1826 (pic16_aopGet): return AOP_ACC when accessing WREG,
1827 (pic16_popGetTempReg): minor modification,
1828 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1829 'pic16_allocWithIdx',
1830 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1831 calling function in absolute addresses,
1832 (genAssign): take into account AOP_ACC asmop,
1833 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1834 * src/pic16/pcoderegs.c: some debug functions and lines added,
1835 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1836 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1838 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1839 call to allocReg, not by manually allocating a new one,
1840 (pic16_assignRegisters): now before going through the register
1841 allocating functions mark all registers as free. This eliminates some
1842 side effects resulting from peephole parser done earlier in the backbone
1844 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1846 * src/SDCCicode.c (geniCodeLogic),

1864 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
1865 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1866 (aopForSym, aopOp): increment asmop.allocated if reused,
1867 (freeAsmop): decrement asmop.allocated and check for zero instead of
1869 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1870 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1871 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1897 made the linker quiet
1899 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1901 * src/pic16/gen.c (genPcall): fixed bug #1443644
1902 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1903 which dumps before the function entry point a data byte which represents
1904 the number of the local variables used by the specified function, added
1905 'xinst' for initial support for Extended Instruction Support,
1906 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1907 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1908 port->fun_prefix anymore (may change later),
1909 (genFunction, genEndFunction): do not store/restore local registers for
1910 _main (this should take care the --main-return command line option in
1912 (genOr): removed some legacy pic-port instructions,
1913 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1914 performing operations with SFR's causes data to be written more than
1915 once to each SFR. Perhaps SFRs should be handled in special cases...
1916 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1918 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1919 into account for stack starting position,
1920 (struct OPTIONS pic16_optionsTable): added command line argument
1921 --extended or -y for Extended Instruction Support,
1922 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1923 (deassignLRs): *** perhaps the most important change, old 'for' code
1924 (commented out for reference), didn't account for some registers which
1925 were left marked 'not free' after a pointer operation. The change
1926 reduces register usage a lot in some cases

4317 * (pic16_popGetTempRegCond): changed function prototype, now
4318 function takes also a bitVector argument v which holds the current
4319 set of registers that are allocated for stack access by aopForSym,
4320 registers allocated in aopForSym for accessing stack symbols are not
4321 any more part of the functions usedRegs field,
4322 * (genCall): some times aopOp is called for a stack variable to be
4323 send, aopForSym might perform the push, if this is true make sure
4324 that genCall doesn't push the variable twice by testing _G.resDirect,
4325 * (genFunction): changed testing for unspecified interrupt number
4326 from 256 to INTNO_UNSPEC,
4327 * modified selection scheme of frame pointer generation. Previously
4328 if function did use local registers a frame pointer was generated,
4329 now a frame pointer is generated only if function has arguments
4330 (that need PLUSW2 register access), or has stack arguments, or the
4331 compiler is not instructed to omit the frame pointer,
4332 * (genEndFunction): before restoring local registers that were saved
4333 in the function preamble, also restore the registers that *might*
4334 have been allocated for stack access,
4335 * (genRet): removed some old comments,
4336 * (genCmp, the active (RN's) version): added a call to the
4337 pic16_genCmp_special function to perform the compare with a more
4338 robust and optimized way,
4339 * (genInline): a feature has been added in inline code generation,
4340 which allows a wildcard variable substitution when writing inline
4341 assembly. Code is incomplete and experimental therefore undocumented,
4342 * (genCast): changed order of aopOp for result and right to allow
4343 aopForSym to directly load the result if possible,
4344 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4345 perform an optimized compare on some selected special occasions,
4346 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4347 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4348 generate an IVT any more,
4349 * src/pic16/main.c (pic16_optionsTable): added command line option
4351 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4352 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4354 * src/pic16/NOTES: Raphael Neider added in list of active developers
4355 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4356 jumptable_end to prevent bug #,
4357 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4358 inCond and outCond fields,
4359 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4360 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4361 turn off register spilling,
4362 * (packRegsForOneUse): synced with other ports' versions although it
4363 is not used currently,
4364 * (pic16_packRegisters): added an optimization while reading
4365 structure bitfields, some registers may be saved (malloc code is
4366 decreased by 80 bytes)
4368 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4370 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4371 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4372 this can be optimized more?
4374 2005-03-10 Raphael Neider <rneider AT web.de>
4376 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4377 genNearPointerGet): (hopefully) fixed access to bitfields via
4378 pointers (p->bitN = x; and x = p->bitN; failed)
4380 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4704 access stack and frame pointers. They are initially assigned to
4705 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4706 accessing SFRs. Updated all occurences of modification of stack or
4707 frame pointer in gen.c and pcode.c,
4708 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4709 assigning of a literal value to pointers,

4752 from Raphael Neider,
4753 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
4754 for 8-bit literals. This fixes some literal operands which are sign
4755 extended to 16-bits ints when instruction needs only 8-bits.

5012 Adding support for replacing ljmps with sjmps in jumptables
5013 generated for switch statements. For now you need to set the
5014 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5015 Now 4 algorithms for mcs51 jumptable generation are used:
5016 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5017 addresses loaded pc-relative for up to 112 cases and stack-pushing
5018 target addresses loaded with offset from dptr for up to 256 cases.

5050 * added libc directory. The current version of LibC contains string
5051 functions, ctype functions and macros and some functions of the
5052 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5053 be extensively tested in the future. Standard disclaimer here.

5067 * (genCmp): experimental code for new genCmp which uses PIC18's
5068 special compare&skip instructions. Initial tests fail some times
5069 with variables grater than 1 byte in size, so new code is disabled,
5070 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5072 * (genCast): began a fix to optimize the casting of a bit to another
5073 bit, now assigning a bitfield to another bitfield will fail, sorry,

5087 registers when it shouldn't,
5088 * src/pic16/ralloc.c (allocReg): add preliminary support for
5089 supporting a limited set of temporary registers,

8098 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8099 loaded with the linker search paths (-L arguments) and the libraries
8100 to be linked with the current source (-l arguments). Changes
8101 currently will affect only the pic16 port.
8102 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8103 include path the port specific paths and port specific libraries,
8104 * gplink command now contains the $3 argument,
8105 * src/pic16/device.h,
8106 * src/pic16/device.c,: structure PIC_device is made public and
8107 renamed to PIC16_device, the same for variable Pics which is renamed

8122 Documenting changes from previous commits.
8123 * configure.in (version 1.56),
8124 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8125 when generating output files to configure the pic16 library,
8126 but now I've commented it out, since gputils aren't installed in the
8127 SF compile farm, so library won't compile
8129 * device/lib/Makefile.in (version 1.56): initially I've added in
8130 target 'all' the prerequestive 'model-pic16' so it compiled the
8131 pic16 library, but now I've commented it out for the same reasons
8133 * added targets 'model-pic16' and 'objects-pic16' to compile the
8135 * added target 'port-specific-objects-pic16' to handle the
8136 generated libraries and copy them into the build/ directory
8137 * added target 'clean-intermediate-pic16' to clean intermediate
8138 files into pic16 directory
8139 * in target 'installdirs' added line to create directory pic16 in

8160 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8161 option so that it actually works. Made it specific to the z80, since
8162 the gbz80 doesn't have these kinds of I/O ports.
8164 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8166 * device/include/z180.h,

8190 via literal number. The symbol is placed in the corresponding
8191 position of the data ram
8192 * (pic16_dump_section): relocatable and absolute uninitialized
8193 data are now emitted in sorted order to reduce section naming,
8194 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8195 weren't marked as being in the access bank,

8388 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8390 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8391 (default behaviour).
8393 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8395 A python script to validate compiler diagnostic messages. It can be
8396 used to verify that sdcc complains about bad c source code and
8397 gives a good location of the error.
8398 * support/valdiag/Makefile,
8399 * support/valdiag/valdiag.py,
8400 * support/valdiag/tests/*

8419 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8421 * sdcc.spec: updated
8422 * device/include/Makefile.in: don't install CVS directories

8424 * doc/Makefile: fixed install, added local_icons
8425 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8426 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8427 * src/ds390/gen.c (genRightShift): fixed bug #870788

8430 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8432 PIC16 port related changes:
8433 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8434 added variable stackPos,
8436 * gen.c: genCall, assignResultValue: added support for
8437 pushing/retrieving function parameters to/from stack,
8438 genFunction,genEndFunction: setup stack frame for the
8440 genAddrOf: will be changed according to bug 863624
8442 * added files genutils.c and genutils.h which contain gen*
8443 debugged and optimised functions extracted from gen.c
8445 * glue.c: added variable 'externs' which holds extern symbols,
8446 pic16emitRegularMap: is modified to properly handle relocatable
8447 symbols under the new scheme,
8448 pic16createInterruptVect: is modified
8449 pic16printPublics: is modified to emit 'global' assembler directives,
8450 added pic16_printExterns to print extern symbols,
8451 pic16glue: initializes stack/frame pointer in the beginning of
8452 the assembly output. Temporary hack, will be corrected later,
8453 because gplink yet does not support stack and SDCC does not
8454 yet support a type of crt0.o object to create the final binary.
8456 * Removed many lines that contain 8051 legacy code.
8457 * The code is finally placed under a 'code' directive.
8458 * Added port specific options.
8460 * _process_pragma: simplified since now we do not need *special*
8461 include file to define SFR registers. But a separate header
8462 will be needed. This will be developed later.
8463 * _pic16_parseOptions: added, parses port specific options:
8464 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8465 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8466 --preplace-udata-with=
8468 * _pic16_setDefaultOptions: modified to initialize section names,
8469 but hack is temporarly out of order since it needs improvement.
8470 * _pic16_genAssemblerPreamble: configuration words are emitted by
8471 their address instead of their name. This part is incomplete and
8472 supports only the 18Fxx2 devices. Other devices will emit an error
8473 during assembly since they do not contain the same set of config
8475 * _pic16_genIVT: is modified,
8477 * pcode.c: added definitions for some hardware registers that are needed
8479 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8480 All PCI entries are updated. Now LFSR is supported.
8481 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8482 * added pic16_newpCodeOpLit2 to support instructions with
8483 two literal arguments
8484 * pic16_pCode2str: corrected code that emits assembler instructions
8485 with two literal operands and those that have an access bit modifier
8486 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8487 this fixes a bug which caused some labels to be lost, when an
8488 assembler directive was added, i.e. banksel,
8489 * pic16_FixRegisterBanking: improved logic that causes the insertion
8491 * InlineFunction: functions that are called once, are not any more
8492 inlined. This can be a port option in the future,
8494 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8496 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8497 hold the corresponding uninitialized symbols,
8498 * pic16_allocProcessorRegister: registers have explicit marked the
8500 * pic16_allocInternalRegister: registers are explicit marked as
8502 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8503 processing list, so bit registers were lost,
8506 * ralloc.h: added field 'accessBank' and original symbol operand
8507 in register definition,
8508 * removed the field isMapped from register definition,
8510 ** Several functions have been removed from various sources:
8511 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8512 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8513 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8514 pic16_assignRelocatableRegisters
8516 ** others have been introduced:
8517 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8518 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8520 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8522 * support/scripts/inc2h.pl: changed definition of BIT_AT
8523 to emit 'sbit at' instead of 'bit at'. This was a request.
8525 PIC16 port related preliminary changes:
8526 * gen.c: prefixed function popRegFromString with
8527 pic16_ and all references to it corrected
8528 * pcode.c: all pic16_pc_* hardware registers prefixed
8529 with underscore (_),
8530 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8531 * ralloc.c: newReg(): when register is REG_SFR then
8532 set address to rIdx,
8533 pic16_allocProcessorRegister(): marks register wasUsed=0
8534 pic16_writeUsedRegs(): added a call to assign processor
8535 registers via pic16_assignFixedRegisters
8537 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8539 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8540 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8541 variables in unused register banks. Also the SSEG is placed
8542 wherever there is enough space for it, and IDATA can be anywhere
8543 in internal RAM. For now compile using -Wl-Y[stack_size].
8544 The mem file is different for this option as well, since it
8545 makes no sense of talking about DSEG lenght.
8547 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8549 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8550 in certain cases, e.g. when ROM assignment, patch provided
8551 from Albert den Haan.
8553 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9555 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9556 fetching of the pointer
9557 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9558 copied from genNearPointerSet()
9559 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9560 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9576 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9577 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9578 type for bits was changed. It resulted in bit variables becoming
9579 global, which is not permitted in PIC 14 assembly output.

9596 A few small changes that speed up the peephole optimizer.
9600 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9602 Try to make the peephole optimizer smarter by maintaining
9603 an association between the assembly source code and the
9604 iCodes that originated them. Put this information to use
9605 with a new peephole rule condition "notVolatile" so that
9606 the rules can be aggressive yet still safe.
9611 * src/mcs51/peeph.def
9613 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9617 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9618 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9619 if the left or right operand symbols have the accuse flag set.
9621 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9623 Changed the type of the result of the ! (NOT) operator to char;
9624 previously it returned the same type as the source. This allows
9625 us to eliminate all the genFloatNot functions (all of its target
9626 implementations were very buggy) since !float can use the same

9638 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9639 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9640 during interrupts. Ensure WSAVE is located at a shared bank address.
9641 2. Fixed page selection in some places
9642 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9643 the registers name strings.
9644 4. Fixed "signed / unsigned compare" compiler warnings.
9645 5. The PIC port manages its own allocation of the general purpose
9646 registers, but makes no attempt to reuse them. As a result when
9647 compiling it soon runs out of general purpose registers. Some
9648 additional code was added to the files pcode.c and device.c to walk
9649 through the function call tree and rename the registers so that they
9659 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9666 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9668 Made bitfield a distinct type from bit so that bitfields
9669 convert as per ANSI C and bits retain their traditional
9670 boolean style behaviour. Implemented bitfield support in
9678 * src/ds390/gen.c: bit v bitfield split
9679 * src/z80/gen.c: New support for bitfields
9680 * support/regression/tests/bitfields.c: reenabled z80,
9683 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9685 Rules 246.x, 247.x relate to bitfields, the others speed up
9686 access to xdata mapped I/O devices.
9688 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9690 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9692 Cleaned up genPackBits and genUnpackBits and added two helper
9693 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9694 for literal assignments in genPackBits (thanks to Frieder for
9700 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9702 Fixed bug #748310 (pointer to function type mishandled when the
9703 function name is omitted). Also fixed a SIGSEGV when a function
9704 attribute (reentrant, etc) is used on a non-function or on a
9705 function but misplaced before the parameter list.
9707 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9709 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9732 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9734 Made the constant following the "interrupt" keyword optional. If
9735 omitted, the function will not automatically be given an entry
9736 in the interrupt vector table (similar to #pragma NOIV, but
9737 less syntacticly kludgy). The interrupt number is also now
9738 range checked. Also fixed a bug in the high order bit example

10268 added if/endif conditional macros to remove options help
10269 messages from optionsTable when a port is not configured, added
10270 support for the PIc16 port in the ports table, when executing
10271 the compiler with no port specified on command line, a default
10272 port is selected with the new macro DEFAULT_PORT which is
10273 defined in port.h, in setDefaultOptions() linkOptions is removed
10274 from initialization assignment, since now it is a set,
10275 parseCmdLine uses setParseWithComma for linkOptions, in
10276 linkEdit() linkOptions are accessed with new function indexSet()
10277 which returns the i'th item of a set variable. See SDCCset.c, in
10278 linkEdit() when calling buildCmdLine(), added linkOptions as
10279 last argument. Now users can pass arguments to gplink via the
10280 -Wl option, main() uses pic16glue() to glue up pic16 programs

10294 gpasm complaining and test the linkage with gplink, _linkCmd and
10295 _asmCmd changed to be more gplink and gpasm friendly
10296 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10297 produced an error when parsed, peep rule 12 is added to utilize
10298 movff, but it is commented out since the pCode does not support
10299 yet a command with 2 address arguments
10301 2003-05-18 <johan AT balder>
10303 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11358 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11359 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11361 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11362 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11364 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11366 * in /sdcc/as/mcs51/ changed these files in order to create an
11367 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11368 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11369 following files to include the previous two files: aslink.dsp,
11370 Makefile.aslink, Makefile.bcc, and Makefile.in.
11372 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11373 .adb instead of .cdb
11375 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11377 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11378 value from option --iram-size.
11380 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11382 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11385 2002-09-18 <wiml AT hhhh.org>
11387 * SDCClrange.h: exposed setFromRange() and setToRange()
11388 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11389 packRegsForAccUse() (bug 542397)
11390 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11391 multiple times and emitting the fetch operations more than once
11392 added aopGetUsesAcc() function to allow binary operators to
11393 fetch their operands in the correct order; made genMinus() emit
11394 compact code for X = LITERAL - Y
11396 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11397 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11398 sprintf() in line 1267.
11400 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11401 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11404 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11405 Changes to aslink (All the changes are marked with 'JCF'):
11407 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11410 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11411 area BSEG. Also moves, if possible, the DATA area down into the internal
11412 ram so more space is available.
11414 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11417 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11418 not bytes. Function summary() which creates a memory usage summary
11419 file with extension .mem. Reports of overlaping stack and small stack
11420 size. If the space for the stack is less than 16 bytes aslink trows a
11423 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11424 the 8051. Option 'y' for memory summary output file.
11426 Changes to sdcc (All the changes are marked with 'JCF'):
11428 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11430 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11431 overlaying area for it (uses RegBankUsed[4]).
11433 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11434 bank zero as used by default. By default aslink locates the stack
11435 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11436 the creation of the .mem file. Delegates the allocation of data area
11437 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11438 the begining of the stack area to aslink.
11440 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11441 glue() in SDCCglue.c creates an area for it.
11443 2002-09-03 Borut Razem <borut.razem AT siol.net>
11444 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11445 sdcc/src/pic/glue.c:
11446 introduced atexit() handler for teporay files removal in case of
11447 errors, assertions, ...
11449 2002-08-29 Borut Razem <borut.razem AT siol.net>
11450 * sdcc/support/cpp2/auto-host_vc_in.h:
11451 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11452 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11453 Maybe there is a similar problem with BORLANDC? It should be checked!
11455 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11456 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11457 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11458 was not executed, and the compiler (cl) launched a warning:
11459 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11461 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11462 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11464 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11465 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11467 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11468 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11469 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11470 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11471 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11472 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11473 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11474 - added Release configuration in VS projects
11475 - review of compiler an linker options
11476 - VC .exe files are generated in bin_vc directory, not to interfere
11477 with binaries generated from other projects (cygwin, mingw, bcc ...)
11479 * sdcc/src/yacc.dsp: added
11481 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11482 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11483 and insert the version number definitions from .version
11485 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11487 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11488 added - genarate auto-host.h using auto-host_vc_in.h as template
11491 removed from CVS, generated automatically
11493 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11494 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11496 2002-08-11 Borut Razem <borut.razem AT siol.net>
11497 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11499 2002-08-10 Borut Razem <borut.razem AT siol.net>
11500 * src/SDCCmain.c (main):
11501 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11502 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11503 The consequence was that some temporary files were not removed.
11506 unification of code in functions tempfilename() and tempfile():
11507 function tempnam() is defined in Visual Studio 6.0 and .NET
11509 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11511 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11512 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11513 - removed compiler command line option /WX: Treats all warnings as errors
11514 - update a list of source files, included into the project
11516 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11517 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11518 changed project type to Generic Project so that can be correcly converted to VS.NET project
11520 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11522 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11524 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11526 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11527 added return 0 statements after assert() to make compiler happy
11529 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11530 added newline in the def file to keep MSC compiler satisfied
11532 * sdcc/src/z80/gen.c:
11533 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11534 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11535 - solved MSC error in function aopDump()
11537 * sdcc_vc.h: define PREFIX as "\\sdcc"
11539 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11540 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11543 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11544 - Rewrote the register banking algorithm.
11545 - Added pCode live-range analysis to registers (for now, only non-used and
11546 singly-used registers optimized away)
11548 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11550 * 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.

11575 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11577 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11579 2002-03-28 Johan Knol <johan AT balder>
11581 * src/SDCCval.c: fixed bug #532436
11583 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11585 Added "char *Processor" field to the port structure.
11588 Added -p option. Allows port dependent processor to be specified.
11591 Initialized the new field char *Processor field to NULL in all ports
11594 Compiler generated registers for interrupt context saving
11595 were not getting allocated.
11597 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11600 Fixed left shift. Will promote the left side of a left shift
11601 if a) left shifting more than size of operand or b) when assigned
11602 to something size > size of left side
11604 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11606 tons of changes. Register allocation has been
11607 rewritten. Added customization for the various PICs. Flow
11608 analysis is restructured. ...
11610 * src/pic/device.h:
11613 * src/pic/device.c:
11614 Added. device.c is a PIC port hack to accomodate variations
11617 2002-03-13 Michael Hope <michaelh AT vroom>
11619 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11621 2002-03-04 johanknol <johanknol AT manik>
11623 * /src/SDCCval.c: fixed
11625 const unsigned char arr[][2] = { { 0, 1 } };
11626 t18.c:1: error: Initializer element is not constant
11628 2002-03-04 bela <bela AT manik>
11630 * /device/include/mcs51reg.h:
11631 ds89c420 register definition update
