1493 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1495 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1496 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1498 One basic decision: e.g. src/clean.mk includes further files. In order
1499 to make this work there are two solutions:
1500 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1501 run configure on them. This way they can use
1502 'include $(srcdir)/port-clean.mk'
1503 - always include clean.mk by the Makefile at the same level. To avoid
1504 that `make clean` tries to include and build Makefile.dep the
1505 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1506 implemented, because now even `make uninstall` doesn't create
1507 Makefile.in. clean.mk could be eliminated by pasting it in
1510 * debugger/mcs51/Makefile.in: build own objects from library sources
1511 (SLIB, SDCC) in current directory
1513 * configure, configure.in: renamed --disable-device-lib-build in
1514 --disable-device-lib; added --enable-doc, the required tools are
1515 searched by configure; added result message; the toolchain for the
1516 belonging ports are now only built, if the port is enabled.
1518 * support/regression/*: all output is written in directory gen, because
1519 the fwk and ports directories don't livet in the build tree using vpath
1521 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1522 --disable-device-lib, added --enable-doc, added section VPATH
1524 * sim/ucsim/configure.in,
1525 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1526 z80 are enabled by default
1528 2006-04-24 Raphael Neider <rneider AT web.de>
1530 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1531 to config word, "pic14_"-prefixed some extern functions
1532 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1533 config word has been found
1534 * src/pic/device.h: added prototypes
1535 * src/pic/pcode.c: added "pic14_"-prefix where needed
1536 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1538 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1798 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1799 implemented patch 1120823 Thanks to Willy De la Court (normal
1800 interrupts need an interrupt number now if they are made critical),
1801 and enabled nesting of critical functions though not for gbz80
1802 (genCritical, genEndCritical): added functions
1803 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1804 * src/z80/mappings.i: added "ei" to all mappings
1806 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1808 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1809 submitted by the Debian SDCC maintainer Aurelien Jarno:
1810 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1811 archive with gcc 4.1 on mips and wrote the patch"
1813 2006-03-16 Raphael Neider <rneider AT web.de>
1815 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1816 the left operand is shorter than the result (c* = lit-c* + int),
1818 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1821 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1823 * src/.version: increased version number to 2.5.5
1824 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1825 linking is done manually in pic16 port's _linkEdit,
1826 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1827 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1828 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1829 allocate asmop as AOP_ACC,
1830 (aopForRemat): added parameter 'bool result' in function declaration,
1831 (pic16_aopGet): return AOP_ACC when accessing WREG,
1832 (pic16_popGetTempReg): minor modification,
1833 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1834 'pic16_allocWithIdx',
1835 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1836 calling function in absolute addresses,
1837 (genAssign): take into account AOP_ACC asmop,
1838 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1839 * src/pic16/pcoderegs.c: some debug functions and lines added,
1840 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1841 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1843 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1844 call to allocReg, not by manually allocating a new one,
1845 (pic16_assignRegisters): now before going through the register
1846 allocating functions mark all registers as free. This eliminates some
1847 side effects resulting from peephole parser done earlier in the backbone
1849 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1870 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1871 (aopForSym, aopOp): increment asmop.allocated if reused,
1872 (freeAsmop): decrement asmop.allocated and check for zero instead of
1874 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1875 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1876 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1899 2006-03-06 Borut Razem <borut.razem AT siol.net>
1901 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1902 made the linker quiet
1904 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1906 * src/pic16/gen.c (genPcall): fixed bug #1443644
1907 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1908 which dumps before the function entry point a data byte which represents
1909 the number of the local variables used by the specified function, added
1910 'xinst' for initial support for Extended Instruction Support,
1911 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1912 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1913 port->fun_prefix anymore (may change later),
1914 (genFunction, genEndFunction): do not store/restore local registers for
1915 _main (this should take care the --main-return command line option in
1917 (genOr): removed some legacy pic-port instructions,
1918 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1919 performing operations with SFR's causes data to be written more than
1920 once to each SFR. Perhaps SFRs should be handled in special cases...
1921 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1923 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1924 into account for stack starting position,
1925 (struct OPTIONS pic16_optionsTable): added command line argument
1926 --extended or -y for Extended Instruction Support,
1927 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1928 (deassignLRs): *** perhaps the most important change, old 'for' code
1929 (commented out for reference), didn't account for some registers which
1930 were left marked 'not free' after a pointer operation. The change
1931 reduces register usage a lot in some cases

4323 function takes also a bitVector argument v which holds the current
4324 set of registers that are allocated for stack access by aopForSym,
4325 registers allocated in aopForSym for accessing stack symbols are not
4326 any more part of the functions usedRegs field,
4327 * (genCall): some times aopOp is called for a stack variable to be
4328 send, aopForSym might perform the push, if this is true make sure
4329 that genCall doesn't push the variable twice by testing _G.resDirect,
4330 * (genFunction): changed testing for unspecified interrupt number
4331 from 256 to INTNO_UNSPEC,
4332 * modified selection scheme of frame pointer generation. Previously
4333 if function did use local registers a frame pointer was generated,
4334 now a frame pointer is generated only if function has arguments
4335 (that need PLUSW2 register access), or has stack arguments, or the
4336 compiler is not instructed to omit the frame pointer,
4337 * (genEndFunction): before restoring local registers that were saved
4338 in the function preamble, also restore the registers that *might*
4339 have been allocated for stack access,
4340 * (genRet): removed some old comments,
4341 * (genCmp, the active (RN's) version): added a call to the
4342 pic16_genCmp_special function to perform the compare with a more
4343 robust and optimized way,
4344 * (genInline): a feature has been added in inline code generation,
4345 which allows a wildcard variable substitution when writing inline
4346 assembly. Code is incomplete and experimental therefore undocumented,
4347 * (genCast): changed order of aopOp for result and right to allow
4348 aopForSym to directly load the result if possible,
4349 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4350 perform an optimized compare on some selected special occasions,
4351 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4352 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4353 generate an IVT any more,
4354 * src/pic16/main.c (pic16_optionsTable): added command line option
4356 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4357 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4359 * src/pic16/NOTES: Raphael Neider added in list of active developers
4360 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4361 jumptable_end to prevent bug #,
4362 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4363 inCond and outCond fields,
4364 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4365 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4366 turn off register spilling,
4367 * (packRegsForOneUse): synced with other ports' versions although it
4368 is not used currently,
4369 * (pic16_packRegisters): added an optimization while reading
4370 structure bitfields, some registers may be saved (malloc code is
4371 decreased by 80 bytes)
4373 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4375 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4376 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4377 this can be optimized more?
4379 2005-03-10 Raphael Neider <rneider AT web.de>
4381 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4382 genNearPointerGet): (hopefully) fixed access to bitfields via
4383 pointers (p->bitN = x; and x = p->bitN; failed)

4709 access stack and frame pointers. They are initially assigned to
4710 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4711 accessing SFRs. Updated all occurences of modification of stack or
4712 frame pointer in gen.c and pcode.c,
4713 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4714 assigning of a literal value to pointers,

4757 from Raphael Neider,
4758 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
4759 for 8-bit literals. This fixes some literal operands which are sign
4760 extended to 16-bits ints when instruction needs only 8-bits.

5019 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5020 Now 4 algorithms for mcs51 jumptable generation are used:
5021 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5055 * added libc directory. The current version of LibC contains string
5056 functions, ctype functions and macros and some functions of the
5057 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5058 be extensively tested in the future. Standard disclaimer here.

5071 * (pic16_storeForReturn): optimized return of 0,
5072 * (genCmp): experimental code for new genCmp which uses PIC18's
5073 special compare&skip instructions. Initial tests fail some times
5074 with variables grater than 1 byte in size, so new code is disabled,
5075 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5077 * (genCast): began a fix to optimize the casting of a bit to another
5078 bit, now assigning a bitfield to another bitfield will fail, sorry,

5087 and 1 for banking instruction,
5088 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5089 caused stop processing pCodes after a inline assembly block,

5092 registers when it shouldn't,
5093 * src/pic16/ralloc.c (allocReg): add preliminary support for
5094 supporting a limited set of temporary registers,
5096 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8103 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8104 loaded with the linker search paths (-L arguments) and the libraries
8105 to be linked with the current source (-l arguments). Changes
8106 currently will affect only the pic16 port.
8107 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8108 include path the port specific paths and port specific libraries,
8109 * gplink command now contains the $3 argument,
8110 * src/pic16/device.h,
8111 * src/pic16/device.c,: structure PIC_device is made public and

8127 Documenting changes from previous commits.
8128 * configure.in (version 1.56),
8129 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8130 when generating output files to configure the pic16 library,
8131 but now I've commented it out, since gputils aren't installed in the
8132 SF compile farm, so library won't compile
8134 * device/lib/Makefile.in (version 1.56): initially I've added in
8135 target 'all' the prerequestive 'model-pic16' so it compiled the
8136 pic16 library, but now I've commented it out for the same reasons
8138 * added targets 'model-pic16' and 'objects-pic16' to compile the
8140 * added target 'port-specific-objects-pic16' to handle the
8141 generated libraries and copy them into the build/ directory
8142 * added target 'clean-intermediate-pic16' to clean intermediate
8143 files into pic16 directory
8144 * in target 'installdirs' added line to create directory pic16 in

8165 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8166 option so that it actually works. Made it specific to the z80, since
8167 the gbz80 doesn't have these kinds of I/O ports.
8169 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8171 * device/include/z180.h,

8195 via literal number. The symbol is placed in the corresponding
8196 position of the data ram
8197 * (pic16_dump_section): relocatable and absolute uninitialized
8198 data are now emitted in sorted order to reduce section naming,
8199 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8200 weren't marked as being in the access bank,

8393 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8395 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8396 (default behaviour).
8398 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8400 A python script to validate compiler diagnostic messages. It can be
8401 used to verify that sdcc complains about bad c source code and
8402 gives a good location of the error.
8403 * support/valdiag/Makefile,
8404 * support/valdiag/valdiag.py,

8424 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8426 * sdcc.spec: updated

8435 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8437 PIC16 port related changes:
8438 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8439 added variable stackPos,
8441 * gen.c: genCall, assignResultValue: added support for
8442 pushing/retrieving function parameters to/from stack,
8443 genFunction,genEndFunction: setup stack frame for the
8445 genAddrOf: will be changed according to bug 863624
8447 * added files genutils.c and genutils.h which contain gen*
8448 debugged and optimised functions extracted from gen.c
8450 * glue.c: added variable 'externs' which holds extern symbols,
8451 pic16emitRegularMap: is modified to properly handle relocatable
8452 symbols under the new scheme,
8453 pic16createInterruptVect: is modified
8454 pic16printPublics: is modified to emit 'global' assembler directives,
8455 added pic16_printExterns to print extern symbols,
8456 pic16glue: initializes stack/frame pointer in the beginning of
8457 the assembly output. Temporary hack, will be corrected later,
8458 because gplink yet does not support stack and SDCC does not
8459 yet support a type of crt0.o object to create the final binary.
8461 * Removed many lines that contain 8051 legacy code.
8462 * The code is finally placed under a 'code' directive.
8463 * Added port specific options.
8465 * _process_pragma: simplified since now we do not need *special*
8466 include file to define SFR registers. But a separate header
8467 will be needed. This will be developed later.
8468 * _pic16_parseOptions: added, parses port specific options:
8469 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8470 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8471 --preplace-udata-with=
8473 * _pic16_setDefaultOptions: modified to initialize section names,
8474 but hack is temporarly out of order since it needs improvement.
8475 * _pic16_genAssemblerPreamble: configuration words are emitted by
8476 their address instead of their name. This part is incomplete and
8477 supports only the 18Fxx2 devices. Other devices will emit an error
8478 during assembly since they do not contain the same set of config
8480 * _pic16_genIVT: is modified,
8482 * pcode.c: added definitions for some hardware registers that are needed
8484 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8485 All PCI entries are updated. Now LFSR is supported.
8486 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8487 * added pic16_newpCodeOpLit2 to support instructions with
8488 two literal arguments
8489 * pic16_pCode2str: corrected code that emits assembler instructions
8490 with two literal operands and those that have an access bit modifier
8491 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8492 this fixes a bug which caused some labels to be lost, when an
8493 assembler directive was added, i.e. banksel,
8494 * pic16_FixRegisterBanking: improved logic that causes the insertion
8496 * InlineFunction: functions that are called once, are not any more
8497 inlined. This can be a port option in the future,
8499 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8501 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8502 hold the corresponding uninitialized symbols,
8503 * pic16_allocProcessorRegister: registers have explicit marked the
8505 * pic16_allocInternalRegister: registers are explicit marked as
8507 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8508 processing list, so bit registers were lost,
8511 * ralloc.h: added field 'accessBank' and original symbol operand
8512 in register definition,
8513 * removed the field isMapped from register definition,
8515 ** Several functions have been removed from various sources:
8516 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8517 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8518 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8519 pic16_assignRelocatableRegisters
8521 ** others have been introduced:
8522 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8523 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8525 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8527 * support/scripts/inc2h.pl: changed definition of BIT_AT
8528 to emit 'sbit at' instead of 'bit at'. This was a request.
8530 PIC16 port related preliminary changes:
8531 * gen.c: prefixed function popRegFromString with
8532 pic16_ and all references to it corrected
8533 * pcode.c: all pic16_pc_* hardware registers prefixed
8534 with underscore (_),
8535 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8536 * ralloc.c: newReg(): when register is REG_SFR then
8537 set address to rIdx,
8538 pic16_allocProcessorRegister(): marks register wasUsed=0
8539 pic16_writeUsedRegs(): added a call to assign processor
8540 registers via pic16_assignFixedRegisters
8542 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8544 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8545 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8546 variables in unused register banks. Also the SSEG is placed
8547 wherever there is enough space for it, and IDATA can be anywhere
8548 in internal RAM. For now compile using -Wl-Y[stack_size].
8549 The mem file is different for this option as well, since it
8550 makes no sense of talking about DSEG lenght.
8552 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8554 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8555 in certain cases, e.g. when ROM assignment, patch provided
8556 from Albert den Haan.
8558 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9561 fetching of the pointer
9562 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9563 copied from genNearPointerSet()
9564 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9565 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9579 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9581 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9582 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9583 type for bits was changed. It resulted in bit variables becoming
9584 global, which is not permitted in PIC 14 assembly output.
9586 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9588 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9599 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9601 A few small changes that speed up the peephole optimizer.
9605 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9607 Try to make the peephole optimizer smarter by maintaining
9608 an association between the assembly source code and the
9609 iCodes that originated them. Put this information to use
9610 with a new peephole rule condition "notVolatile" so that
9611 the rules can be aggressive yet still safe.
9616 * src/mcs51/peeph.def
9618 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9622 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9623 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9624 if the left or right operand symbols have the accuse flag set.
9626 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9628 Changed the type of the result of the ! (NOT) operator to char;
9629 previously it returned the same type as the source. This allows
9630 us to eliminate all the genFloatNot functions (all of its target
9631 implementations were very buggy) since !float can use the same
9634 * src/SDCCicode.c (ast2iCode): ! returns char
9635 * src/mcs51/gen.c (genNot, genNotFloat),
9636 * src/ds390/gen.c (genNot, genNotFloat),
9637 * src/z80/gen.c (genNot, genNotFloat),
9638 * src/pic/gen.c (genNot, genNotFloat),
9639 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9641 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9643 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9644 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9645 during interrupts. Ensure WSAVE is located at a shared bank address.
9646 2. Fixed page selection in some places
9647 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9648 the registers name strings.
9649 4. Fixed "signed / unsigned compare" compiler warnings.
9650 5. The PIC port manages its own allocation of the general purpose
9651 registers, but makes no attempt to reuse them. As a result when
9652 compiling it soon runs out of general purpose registers. Some
9653 additional code was added to the files pcode.c and device.c to walk
9654 through the function call tree and rename the registers so that they
9664 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9665 genPlus() & genMinus() when the result is the same as left or right
9667 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9671 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9673 Made bitfield a distinct type from bit so that bitfields
9674 convert as per ANSI C and bits retain their traditional
9675 boolean style behaviour. Implemented bitfield support in
9683 * src/ds390/gen.c: bit v bitfield split
9684 * src/z80/gen.c: New support for bitfields
9685 * support/regression/tests/bitfields.c: reenabled z80,
9688 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9690 Rules 246.x, 247.x relate to bitfields, the others speed up
9691 access to xdata mapped I/O devices.
9693 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9695 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9697 Cleaned up genPackBits and genUnpackBits and added two helper
9698 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9699 for literal assignments in genPackBits (thanks to Frieder for
9705 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9707 Fixed bug #748310 (pointer to function type mishandled when the
9708 function name is omitted). Also fixed a SIGSEGV when a function
9709 attribute (reentrant, etc) is used on a non-function or on a
9710 function but misplaced before the parameter list.
9712 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9714 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9715 * support/Util/SDCCerr.h,
9716 * support/Util/SDCCerr.c: Added func attr misuse error msg

9737 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9739 Made the constant following the "interrupt" keyword optional. If
9740 omitted, the function will not automatically be given an entry
9741 in the interrupt vector table (similar to #pragma NOIV, but
9742 less syntacticly kludgy). The interrupt number is also now
9743 range checked. Also fixed a bug in the high order bit example

9751 * support/Util/SDCCerr.h
9754 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9756 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9757 * src/SDCCicode.c (operandOperation): rewritten some ops
9758 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9759 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9761 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9762 be re-activated by defining REDUCE_LITERALS)
9763 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9764 unsigned, but are signed by default
9765 * src/SDCCval.c (constVal): rearranged
9766 * src/SDCCval.c (valMod): preliminary fix
9767 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10274 messages from optionsTable when a port is not configured, added
10275 support for the PIc16 port in the ports table, when executing
10276 the compiler with no port specified on command line, a default
10277 port is selected with the new macro DEFAULT_PORT which is
10278 defined in port.h, in setDefaultOptions() linkOptions is removed
10279 from initialization assignment, since now it is a set,
10280 parseCmdLine uses setParseWithComma for linkOptions, in
10281 linkEdit() linkOptions are accessed with new function indexSet()
10282 which returns the i'th item of a set variable. See SDCCset.c, in
10283 linkEdit() when calling buildCmdLine(), added linkOptions as
10284 last argument. Now users can pass arguments to gplink via the
10285 -Wl option, main() uses pic16glue() to glue up pic16 programs

10299 gpasm complaining and test the linkage with gplink, _linkCmd and
10300 _asmCmd changed to be more gplink and gpasm friendly
10301 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10302 produced an error when parsed, peep rule 12 is added to utilize
10303 movff, but it is commented out since the pCode does not support
10304 yet a command with 2 address arguments
10306 2003-05-18 <johan AT balder>
10308 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11366 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11367 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11369 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11371 * in /sdcc/as/mcs51/ changed these files in order to create an
11372 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11373 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11374 following files to include the previous two files: aslink.dsp,
11375 Makefile.aslink, Makefile.bcc, and Makefile.in.
11377 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11378 .adb instead of .cdb
11380 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11382 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11383 value from option --iram-size.
11385 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11387 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11390 2002-09-18 <wiml AT hhhh.org>
11392 * SDCClrange.h: exposed setFromRange() and setToRange()
11393 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11394 packRegsForAccUse() (bug 542397)
11395 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11396 multiple times and emitting the fetch operations more than once
11397 added aopGetUsesAcc() function to allow binary operators to
11398 fetch their operands in the correct order; made genMinus() emit
11399 compact code for X = LITERAL - Y
11401 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11402 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11403 sprintf() in line 1267.
11405 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11406 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11409 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11410 Changes to aslink (All the changes are marked with 'JCF'):
11412 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11415 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11416 area BSEG. Also moves, if possible, the DATA area down into the internal
11417 ram so more space is available.
11419 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11422 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11423 not bytes. Function summary() which creates a memory usage summary
11424 file with extension .mem. Reports of overlaping stack and small stack
11425 size. If the space for the stack is less than 16 bytes aslink trows a
11428 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11429 the 8051. Option 'y' for memory summary output file.
11431 Changes to sdcc (All the changes are marked with 'JCF'):
11433 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11435 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11436 overlaying area for it (uses RegBankUsed[4]).
11438 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11439 bank zero as used by default. By default aslink locates the stack
11440 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11441 the creation of the .mem file. Delegates the allocation of data area
11442 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11443 the begining of the stack area to aslink.
11445 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11446 glue() in SDCCglue.c creates an area for it.
11448 2002-09-03 Borut Razem <borut.razem AT siol.net>
11449 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11450 sdcc/src/pic/glue.c:
11451 introduced atexit() handler for teporay files removal in case of
11452 errors, assertions, ...
11454 2002-08-29 Borut Razem <borut.razem AT siol.net>
11455 * sdcc/support/cpp2/auto-host_vc_in.h:
11456 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11457 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11458 Maybe there is a similar problem with BORLANDC? It should be checked!
11460 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11461 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11462 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11463 was not executed, and the compiler (cl) launched a warning:
11464 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11466 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11467 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11469 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11470 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11472 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11473 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11474 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11475 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11476 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11477 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11478 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11479 - added Release configuration in VS projects
11480 - review of compiler an linker options
11481 - VC .exe files are generated in bin_vc directory, not to interfere
11482 with binaries generated from other projects (cygwin, mingw, bcc ...)
11484 * sdcc/src/yacc.dsp: added
11486 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11487 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11488 and insert the version number definitions from .version
11490 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11492 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11493 added - genarate auto-host.h using auto-host_vc_in.h as template
11496 removed from CVS, generated automatically
11498 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11499 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11501 2002-08-11 Borut Razem <borut.razem AT siol.net>
11502 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11504 2002-08-10 Borut Razem <borut.razem AT siol.net>
11505 * src/SDCCmain.c (main):
11506 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11507 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11508 The consequence was that some temporary files were not removed.
11511 unification of code in functions tempfilename() and tempfile():
11512 function tempnam() is defined in Visual Studio 6.0 and .NET
11514 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11516 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11517 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11518 - removed compiler command line option /WX: Treats all warnings as errors
11519 - update a list of source files, included into the project
11521 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11522 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11523 changed project type to Generic Project so that can be correcly converted to VS.NET project
11525 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11527 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11529 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11531 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11532 added return 0 statements after assert() to make compiler happy
11534 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11535 added newline in the def file to keep MSC compiler satisfied
11537 * sdcc/src/z80/gen.c:
11538 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11539 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11540 - solved MSC error in function aopDump()
11542 * sdcc_vc.h: define PREFIX as "\\sdcc"
11544 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11545 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11547 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11548 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11549 - Rewrote the register banking algorithm.
11550 - Added pCode live-range analysis to registers (for now, only non-used and
11551 singly-used registers optimized away)
11553 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11555 * 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.

11580 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11582 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11584 2002-03-28 Johan Knol <johan AT balder>
11586 * src/SDCCval.c: fixed bug #532436
11588 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11590 Added "char *Processor" field to the port structure.
11593 Added -p option. Allows port dependent processor to be specified.
11596 Initialized the new field char *Processor field to NULL in all ports
11599 Compiler generated registers for interrupt context saving
11600 were not getting allocated.
11602 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11605 Fixed left shift. Will promote the left side of a left shift
11606 if a) left shifting more than size of operand or b) when assigned
11607 to something size > size of left side
11609 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11611 tons of changes. Register allocation has been
11612 rewritten. Added customization for the various PICs. Flow
11613 analysis is restructured. ...
11615 * src/pic/device.h:
11618 * src/pic/device.c:
11619 Added. device.c is a PIC port hack to accomodate variations
11622 2002-03-13 Michael Hope <michaelh AT vroom>
11624 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11626 2002-03-04 johanknol <johanknol AT manik>
11628 * /src/SDCCval.c: fixed
11630 const unsigned char arr[][2] = { { 0, 1 } };
11631 t18.c:1: error: Initializer element is not constant
11633 2002-03-04 bela <bela AT manik>
11635 * /device/include/mcs51reg.h:
11636 ds89c420 register definition update
11638 2002-03-03 <johan AT FRIJA>
