1518 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1520 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1521 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1523 One basic decision: e.g. src/clean.mk includes further files. In order
1524 to make this work there are two solutions:
1525 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1526 run configure on them. This way they can use
1527 'include $(srcdir)/port-clean.mk'
1528 - always include clean.mk by the Makefile at the same level. To avoid
1529 that `make clean` tries to include and build Makefile.dep the
1530 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1531 implemented, because now even `make uninstall` doesn't create
1532 Makefile.in. clean.mk could be eliminated by pasting it in
1535 * debugger/mcs51/Makefile.in: build own objects from library sources
1536 (SLIB, SDCC) in current directory
1538 * configure, configure.in: renamed --disable-device-lib-build in
1539 --disable-device-lib; added --enable-doc, the required tools are
1540 searched by configure; added result message; the toolchain for the
1541 belonging ports are now only built, if the port is enabled.
1543 * support/regression/*: all output is written in directory gen, because
1544 the fwk and ports directories don't livet in the build tree using vpath
1546 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1547 --disable-device-lib, added --enable-doc, added section VPATH
1549 * sim/ucsim/configure.in,
1550 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1551 z80 are enabled by default
1553 2006-04-24 Raphael Neider <rneider AT web.de>
1555 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1556 to config word, "pic14_"-prefixed some extern functions
1557 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1558 config word has been found
1559 * src/pic/device.h: added prototypes
1560 * src/pic/pcode.c: added "pic14_"-prefix where needed
1561 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1563 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1577 fixes #1469504 and #1474602,
1578 (pCodeRegOptimizeRegUsage): fixed typo in comment

1582 * device/examples/main8051.c: deleted - it was removed from CVS

1810 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1812 * src/SDCCpeeph.c (operandsLiteral): new, added,

1823 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1824 implemented patch 1120823 Thanks to Willy De la Court (normal
1825 interrupts need an interrupt number now if they are made critical),
1826 and enabled nesting of critical functions though not for gbz80
1827 (genCritical, genEndCritical): added functions
1828 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1829 * src/z80/mappings.i: added "ei" to all mappings

1834 submitted by the Debian SDCC maintainer Aurelien Jarno:
1835 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1836 archive with gcc 4.1 on mips and wrote the patch"
1838 2006-03-16 Raphael Neider <rneider AT web.de>
1840 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1841 the left operand is shorter than the result (c* = lit-c* + int),
1843 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1846 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1848 * src/.version: increased version number to 2.5.5
1849 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1850 linking is done manually in pic16 port's _linkEdit,
1851 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1852 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1853 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1854 allocate asmop as AOP_ACC,
1855 (aopForRemat): added parameter 'bool result' in function declaration,
1856 (pic16_aopGet): return AOP_ACC when accessing WREG,
1857 (pic16_popGetTempReg): minor modification,
1858 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1859 'pic16_allocWithIdx',
1860 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1861 calling function in absolute addresses,
1862 (genAssign): take into account AOP_ACC asmop,
1863 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1864 * src/pic16/pcoderegs.c: some debug functions and lines added,
1865 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1866 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1868 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1869 call to allocReg, not by manually allocating a new one,
1870 (pic16_assignRegisters): now before going through the register
1871 allocating functions mark all registers as free. This eliminates some
1872 side effects resulting from peephole parser done earlier in the backbone
1874 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1876 * src/SDCCicode.c (geniCodeLogic),

1895 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1896 (aopForSym, aopOp): increment asmop.allocated if reused,
1897 (freeAsmop): decrement asmop.allocated and check for zero instead of
1899 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1900 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1901 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1924 2006-03-06 Borut Razem <borut.razem AT siol.net>
1926 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1927 made the linker quiet
1929 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1931 * src/pic16/gen.c (genPcall): fixed bug #1443644
1932 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1933 which dumps before the function entry point a data byte which represents
1934 the number of the local variables used by the specified function, added
1935 'xinst' for initial support for Extended Instruction Support,
1936 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1937 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1938 port->fun_prefix anymore (may change later),
1939 (genFunction, genEndFunction): do not store/restore local registers for
1940 _main (this should take care the --main-return command line option in
1942 (genOr): removed some legacy pic-port instructions,
1943 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1944 performing operations with SFR's causes data to be written more than
1945 once to each SFR. Perhaps SFRs should be handled in special cases...
1946 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1948 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1949 into account for stack starting position,

1951 --extended or -y for Extended Instruction Support,
1952 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1953 (deassignLRs): *** perhaps the most important change, old 'for' code
1954 (commented out for reference), didn't account for some registers which
1955 were left marked 'not free' after a pointer operation. The change
1956 reduces register usage a lot in some cases

4320 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4321 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4323 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4325 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4326 prevent compiler warning
4328 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4330 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4331 moved to level 0 and declared as static. Also they are explicit
4332 placed in access bank. This was necessery because some times they
4333 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4334 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4335 optimizations. Currently only compare to unsigned char is implemented,
4336 * src/pic16/gen.c: added fReturnIdx array,
4337 * (struct resolvedIfx) is moved to gen.h and made public,
4338 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4339 * (aopForSym): added an optimization to directly store in stack of
4340 the operand of a SEND iCode,
4341 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4342 but as registers instead (AOP_REG) using the fReturnIdx array,
4343 * (pic16_freeAsmop): remove the freed register from the
4344 _G.sregsAlloc field,
4345 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4346 a compare of 'WREG',
4347 * (pic16_popGetTempRegCond): changed function prototype, now
4348 function takes also a bitVector argument v which holds the current
4349 set of registers that are allocated for stack access by aopForSym,
4350 registers allocated in aopForSym for accessing stack symbols are not
4351 any more part of the functions usedRegs field,
4352 * (genCall): some times aopOp is called for a stack variable to be
4353 send, aopForSym might perform the push, if this is true make sure
4354 that genCall doesn't push the variable twice by testing _G.resDirect,
4355 * (genFunction): changed testing for unspecified interrupt number
4356 from 256 to INTNO_UNSPEC,
4357 * modified selection scheme of frame pointer generation. Previously
4358 if function did use local registers a frame pointer was generated,
4359 now a frame pointer is generated only if function has arguments
4360 (that need PLUSW2 register access), or has stack arguments, or the
4361 compiler is not instructed to omit the frame pointer,
4362 * (genEndFunction): before restoring local registers that were saved
4363 in the function preamble, also restore the registers that *might*
4364 have been allocated for stack access,
4365 * (genRet): removed some old comments,
4366 * (genCmp, the active (RN's) version): added a call to the
4367 pic16_genCmp_special function to perform the compare with a more
4368 robust and optimized way,
4369 * (genInline): a feature has been added in inline code generation,
4370 which allows a wildcard variable substitution when writing inline
4371 assembly. Code is incomplete and experimental therefore undocumented,
4372 * (genCast): changed order of aopOp for result and right to allow
4373 aopForSym to directly load the result if possible,
4374 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4375 perform an optimized compare on some selected special occasions,
4376 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4377 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4378 generate an IVT any more,
4379 * src/pic16/main.c (pic16_optionsTable): added command line option
4381 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4382 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4384 * src/pic16/NOTES: Raphael Neider added in list of active developers
4385 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4386 jumptable_end to prevent bug #,
4387 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4388 inCond and outCond fields,
4389 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4390 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4391 turn off register spilling,
4392 * (packRegsForOneUse): synced with other ports' versions although it
4393 is not used currently,
4394 * (pic16_packRegisters): added an optimization while reading
4395 structure bitfields, some registers may be saved (malloc code is
4396 decreased by 80 bytes)
4398 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4400 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4401 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4402 this can be optimized more?
4404 2005-03-10 Raphael Neider <rneider AT web.de>
4406 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4407 genNearPointerGet): (hopefully) fixed access to bitfields via
4408 pointers (p->bitN = x; and x = p->bitN; failed)

4734 access stack and frame pointers. They are initially assigned to
4735 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4736 accessing SFRs. Updated all occurences of modification of stack or
4737 frame pointer in gen.c and pcode.c,
4738 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4739 assigning of a literal value to pointers,

5042 Adding support for replacing ljmps with sjmps in jumptables
5043 generated for switch statements. For now you need to set the
5044 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5045 Now 4 algorithms for mcs51 jumptable generation are used:
5046 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5047 addresses loaded pc-relative for up to 112 cases and stack-pushing
5048 target addresses loaded with offset from dptr for up to 256 cases.

5078 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5080 * added libc directory. The current version of LibC contains string
5081 functions, ctype functions and macros and some functions of the
5082 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5083 be extensively tested in the future. Standard disclaimer here.
5084 Library is not automatically build yet. But one can build it by

5096 * (pic16_storeForReturn): optimized return of 0,
5097 * (genCmp): experimental code for new genCmp which uses PIC18's
5098 special compare&skip instructions. Initial tests fail some times
5099 with variables grater than 1 byte in size, so new code is disabled,
5100 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5102 * (genCast): began a fix to optimize the casting of a bit to another
5103 bit, now assigning a bitfield to another bitfield will fail, sorry,

5112 and 1 for banking instruction,
5113 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5114 caused stop processing pCodes after a inline assembly block,
5115 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5117 registers when it shouldn't,
5118 * src/pic16/ralloc.c (allocReg): add preliminary support for
5119 supporting a limited set of temporary registers,
5121 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8128 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8129 loaded with the linker search paths (-L arguments) and the libraries
8130 to be linked with the current source (-l arguments). Changes
8131 currently will affect only the pic16 port.
8132 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8133 include path the port specific paths and port specific libraries,
8134 * gplink command now contains the $3 argument,
8135 * src/pic16/device.h,

8152 Documenting changes from previous commits.
8153 * configure.in (version 1.56),
8154 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8155 when generating output files to configure the pic16 library,
8156 but now I've commented it out, since gputils aren't installed in the
8157 SF compile farm, so library won't compile
8159 * device/lib/Makefile.in (version 1.56): initially I've added in
8160 target 'all' the prerequestive 'model-pic16' so it compiled the
8161 pic16 library, but now I've commented it out for the same reasons
8163 * added targets 'model-pic16' and 'objects-pic16' to compile the
8165 * added target 'port-specific-objects-pic16' to handle the
8166 generated libraries and copy them into the build/ directory
8167 * added target 'clean-intermediate-pic16' to clean intermediate
8168 files into pic16 directory
8169 * in target 'installdirs' added line to create directory pic16 in
8170 the installation path

8173 added lines to copy all header files to installation path,
8174 * in target 'installdirs' added line create directory for pic16
8175 headers in the installation path

8191 option so that it actually works. Made it specific to the z80, since
8192 the gbz80 doesn't have these kinds of I/O ports.
8194 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8196 * device/include/z180.h,

8220 via literal number. The symbol is placed in the corresponding
8221 position of the data ram
8222 * (pic16_dump_section): relocatable and absolute uninitialized
8223 data are now emitted in sorted order to reduce section naming,
8224 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8225 weren't marked as being in the access bank,

8303 UPPER for immediate operands,
8304 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8306 * src/pic16/peeph.def: all peepholes with movff are commented out,
8307 because there is a problem in the pcode peep optimizer,
8308 * src/pic16/ralloc.c: the register allocator can now reuse local
8309 function symbols for another function. This saves register usage.
8310 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8312 Added file src/pic16/NOTES with information about program writing on
8313 the current port version.

8401 include information about variables allocated to the overlay
8404 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8406 * as/mcs51/lkmain.c: Help about -Y option

8418 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8420 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8421 (default behaviour).
8423 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8425 A python script to validate compiler diagnostic messages. It can be
8426 used to verify that sdcc complains about bad c source code and
8427 gives a good location of the error.
8428 * support/valdiag/Makefile,
8429 * support/valdiag/valdiag.py,
8430 * support/valdiag/tests/*

8447 Bug reported from Jesus Calvino-Fraga
8449 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8451 * sdcc.spec: updated
8452 * device/include/Makefile.in: don't install CVS directories
8453 * device/lib/Makefile.in: added removal of CVS directories after install
8454 * doc/Makefile: fixed install, added local_icons
8455 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8456 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8457 * src/ds390/gen.c (genRightShift): fixed bug #870788
8458 * src/SDCCast.c (decorateType): fixed bug #870781
8460 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8462 PIC16 port related changes:
8463 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8464 added variable stackPos,
8466 * gen.c: genCall, assignResultValue: added support for
8467 pushing/retrieving function parameters to/from stack,
8468 genFunction,genEndFunction: setup stack frame for the
8470 genAddrOf: will be changed according to bug 863624
8472 * added files genutils.c and genutils.h which contain gen*
8473 debugged and optimised functions extracted from gen.c
8475 * glue.c: added variable 'externs' which holds extern symbols,
8476 pic16emitRegularMap: is modified to properly handle relocatable
8477 symbols under the new scheme,
8478 pic16createInterruptVect: is modified
8479 pic16printPublics: is modified to emit 'global' assembler directives,
8480 added pic16_printExterns to print extern symbols,
8481 pic16glue: initializes stack/frame pointer in the beginning of
8482 the assembly output. Temporary hack, will be corrected later,
8483 because gplink yet does not support stack and SDCC does not
8484 yet support a type of crt0.o object to create the final binary.
8486 * Removed many lines that contain 8051 legacy code.
8487 * The code is finally placed under a 'code' directive.
8488 * Added port specific options.
8490 * _process_pragma: simplified since now we do not need *special*
8491 include file to define SFR registers. But a separate header
8492 will be needed. This will be developed later.
8493 * _pic16_parseOptions: added, parses port specific options:
8494 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8495 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8496 --preplace-udata-with=
8498 * _pic16_setDefaultOptions: modified to initialize section names,
8499 but hack is temporarly out of order since it needs improvement.
8500 * _pic16_genAssemblerPreamble: configuration words are emitted by
8501 their address instead of their name. This part is incomplete and
8502 supports only the 18Fxx2 devices. Other devices will emit an error
8503 during assembly since they do not contain the same set of config
8505 * _pic16_genIVT: is modified,
8507 * pcode.c: added definitions for some hardware registers that are needed
8509 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8510 All PCI entries are updated. Now LFSR is supported.
8511 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8512 * added pic16_newpCodeOpLit2 to support instructions with
8513 two literal arguments
8514 * pic16_pCode2str: corrected code that emits assembler instructions
8515 with two literal operands and those that have an access bit modifier
8516 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8517 this fixes a bug which caused some labels to be lost, when an
8518 assembler directive was added, i.e. banksel,
8519 * pic16_FixRegisterBanking: improved logic that causes the insertion
8521 * InlineFunction: functions that are called once, are not any more
8522 inlined. This can be a port option in the future,
8524 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8526 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8527 hold the corresponding uninitialized symbols,
8528 * pic16_allocProcessorRegister: registers have explicit marked the
8530 * pic16_allocInternalRegister: registers are explicit marked as
8532 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8533 processing list, so bit registers were lost,
8536 * ralloc.h: added field 'accessBank' and original symbol operand
8537 in register definition,
8538 * removed the field isMapped from register definition,
8540 ** Several functions have been removed from various sources:
8541 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8542 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8543 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8544 pic16_assignRelocatableRegisters
8546 ** others have been introduced:
8547 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8548 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8550 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8552 * support/scripts/inc2h.pl: changed definition of BIT_AT
8553 to emit 'sbit at' instead of 'bit at'. This was a request.
8555 PIC16 port related preliminary changes:
8556 * gen.c: prefixed function popRegFromString with
8557 pic16_ and all references to it corrected
8558 * pcode.c: all pic16_pc_* hardware registers prefixed
8559 with underscore (_),
8560 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8561 * ralloc.c: newReg(): when register is REG_SFR then
8562 set address to rIdx,
8563 pic16_allocProcessorRegister(): marks register wasUsed=0
8564 pic16_writeUsedRegs(): added a call to assign processor
8565 registers via pic16_assignFixedRegisters
8567 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8569 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8570 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8571 variables in unused register banks. Also the SSEG is placed
8572 wherever there is enough space for it, and IDATA can be anywhere
8573 in internal RAM. For now compile using -Wl-Y[stack_size].
8574 The mem file is different for this option as well, since it
8575 makes no sense of talking about DSEG lenght.
8577 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8579 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8580 in certain cases, e.g. when ROM assignment, patch provided
8581 from Albert den Haan.
8583 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9469 support for standard C idiom of memory mapped variables; for
9470 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9471 to xdata int at 0x1234 tempvar = 1.
9472 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9473 provided by Akiya ISHIDA

9585 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9586 fetching of the pointer
9587 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9588 copied from genNearPointerSet()
9589 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9590 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9604 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9606 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9607 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9608 type for bits was changed. It resulted in bit variables becoming
9609 global, which is not permitted in PIC 14 assembly output.
9611 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9626 A few small changes that speed up the peephole optimizer.
9630 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9632 Try to make the peephole optimizer smarter by maintaining
9633 an association between the assembly source code and the
9634 iCodes that originated them. Put this information to use
9635 with a new peephole rule condition "notVolatile" so that
9636 the rules can be aggressive yet still safe.
9641 * src/mcs51/peeph.def
9643 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9647 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9648 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9649 if the left or right operand symbols have the accuse flag set.
9651 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9653 Changed the type of the result of the ! (NOT) operator to char;
9654 previously it returned the same type as the source. This allows
9655 us to eliminate all the genFloatNot functions (all of its target
9656 implementations were very buggy) since !float can use the same
9659 * src/SDCCicode.c (ast2iCode): ! returns char

9668 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9669 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9670 during interrupts. Ensure WSAVE is located at a shared bank address.
9671 2. Fixed page selection in some places
9672 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9673 the registers name strings.
9674 4. Fixed "signed / unsigned compare" compiler warnings.
9675 5. The PIC port manages its own allocation of the general purpose
9676 registers, but makes no attempt to reuse them. As a result when
9677 compiling it soon runs out of general purpose registers. Some
9678 additional code was added to the files pcode.c and device.c to walk
9679 through the function call tree and rename the registers so that they
9689 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9690 genPlus() & genMinus() when the result is the same as left or right

9696 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9698 Made bitfield a distinct type from bit so that bitfields
9699 convert as per ANSI C and bits retain their traditional
9700 boolean style behaviour. Implemented bitfield support in
9708 * src/ds390/gen.c: bit v bitfield split
9709 * src/z80/gen.c: New support for bitfields
9710 * support/regression/tests/bitfields.c: reenabled z80,
9713 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9715 Rules 246.x, 247.x relate to bitfields, the others speed up
9716 access to xdata mapped I/O devices.
9718 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9720 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9722 Cleaned up genPackBits and genUnpackBits and added two helper
9723 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9724 for literal assignments in genPackBits (thanks to Frieder for
9730 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9732 Fixed bug #748310 (pointer to function type mishandled when the
9733 function name is omitted). Also fixed a SIGSEGV when a function
9734 attribute (reentrant, etc) is used on a non-function or on a
9735 function but misplaced before the parameter list.
9737 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9739 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9740 * support/Util/SDCCerr.h,

9762 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9764 Made the constant following the "interrupt" keyword optional. If
9765 omitted, the function will not automatically be given an entry
9766 in the interrupt vector table (similar to #pragma NOIV, but
9767 less syntacticly kludgy). The interrupt number is also now
9768 range checked. Also fixed a bug in the high order bit example

9782 * src/SDCCicode.c (operandOperation): rewritten some ops
9783 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9784 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9786 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9787 be re-activated by defining REDUCE_LITERALS)

9789 unsigned, but are signed by default
9790 * src/SDCCval.c (constVal): rearranged
9791 * src/SDCCval.c (valMod): preliminary fix
9792 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10245 the regression tests I'm not brave enough to enable 245.b, 245.c
10246 * doc/sdccman.lyx: added latex preamble for hyperref package.
10247 Using pdflatex this will give you a hyperlinked pdf file with

10298 added if/endif conditional macros to remove options help
10299 messages from optionsTable when a port is not configured, added
10300 support for the PIc16 port in the ports table, when executing
10301 the compiler with no port specified on command line, a default
10302 port is selected with the new macro DEFAULT_PORT which is
10303 defined in port.h, in setDefaultOptions() linkOptions is removed
10304 from initialization assignment, since now it is a set,
10305 parseCmdLine uses setParseWithComma for linkOptions, in
10306 linkEdit() linkOptions are accessed with new function indexSet()
10307 which returns the i'th item of a set variable. See SDCCset.c, in
10308 linkEdit() when calling buildCmdLine(), added linkOptions as
10309 last argument. Now users can pass arguments to gplink via the
10310 -Wl option, main() uses pic16glue() to glue up pic16 programs

10324 gpasm complaining and test the linkage with gplink, _linkCmd and
10325 _asmCmd changed to be more gplink and gpasm friendly
10326 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10327 produced an error when parsed, peep rule 12 is added to utilize
10328 movff, but it is commented out since the pCode does not support
10329 yet a command with 2 address arguments
10331 2003-05-18 <johan AT balder>
10333 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11370 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11371 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11381 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11382 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11385 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11386 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11388 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11389 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11391 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11392 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11394 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11396 * in /sdcc/as/mcs51/ changed these files in order to create an
11397 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11398 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11399 following files to include the previous two files: aslink.dsp,
11400 Makefile.aslink, Makefile.bcc, and Makefile.in.
11402 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11403 .adb instead of .cdb
11405 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11407 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11408 value from option --iram-size.
11410 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11412 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11415 2002-09-18 <wiml AT hhhh.org>
11417 * SDCClrange.h: exposed setFromRange() and setToRange()
11418 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11419 packRegsForAccUse() (bug 542397)
11420 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11421 multiple times and emitting the fetch operations more than once
11422 added aopGetUsesAcc() function to allow binary operators to
11423 fetch their operands in the correct order; made genMinus() emit
11424 compact code for X = LITERAL - Y
11426 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11427 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11428 sprintf() in line 1267.
11430 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11431 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11434 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11435 Changes to aslink (All the changes are marked with 'JCF'):
11437 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11440 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11441 area BSEG. Also moves, if possible, the DATA area down into the internal
11442 ram so more space is available.
11444 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11447 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11448 not bytes. Function summary() which creates a memory usage summary
11449 file with extension .mem. Reports of overlaping stack and small stack
11450 size. If the space for the stack is less than 16 bytes aslink trows a
11453 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11454 the 8051. Option 'y' for memory summary output file.
11456 Changes to sdcc (All the changes are marked with 'JCF'):
11458 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11460 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11461 overlaying area for it (uses RegBankUsed[4]).
11463 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11464 bank zero as used by default. By default aslink locates the stack
11465 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11466 the creation of the .mem file. Delegates the allocation of data area
11467 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11468 the begining of the stack area to aslink.
11470 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11471 glue() in SDCCglue.c creates an area for it.
11473 2002-09-03 Borut Razem <borut.razem AT siol.net>
11474 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11475 sdcc/src/pic/glue.c:
11476 introduced atexit() handler for teporay files removal in case of
11477 errors, assertions, ...
11479 2002-08-29 Borut Razem <borut.razem AT siol.net>
11480 * sdcc/support/cpp2/auto-host_vc_in.h:
11481 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11482 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11483 Maybe there is a similar problem with BORLANDC? It should be checked!
11485 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11486 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11487 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11488 was not executed, and the compiler (cl) launched a warning:
11489 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11491 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11492 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11494 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11495 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11497 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11498 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11499 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11500 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11501 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11502 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11503 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11504 - added Release configuration in VS projects
11505 - review of compiler an linker options
11506 - VC .exe files are generated in bin_vc directory, not to interfere
11507 with binaries generated from other projects (cygwin, mingw, bcc ...)
11509 * sdcc/src/yacc.dsp: added
11511 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11512 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11513 and insert the version number definitions from .version
11515 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11517 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11518 added - genarate auto-host.h using auto-host_vc_in.h as template
11521 removed from CVS, generated automatically
11523 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11524 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11526 2002-08-11 Borut Razem <borut.razem AT siol.net>
11527 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11529 2002-08-10 Borut Razem <borut.razem AT siol.net>
11530 * src/SDCCmain.c (main):
11531 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11532 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11533 The consequence was that some temporary files were not removed.
11536 unification of code in functions tempfilename() and tempfile():
11537 function tempnam() is defined in Visual Studio 6.0 and .NET
11539 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11541 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11542 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11543 - removed compiler command line option /WX: Treats all warnings as errors
11544 - update a list of source files, included into the project
11546 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11547 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11548 changed project type to Generic Project so that can be correcly converted to VS.NET project
11550 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11552 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11554 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11556 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11557 added return 0 statements after assert() to make compiler happy
11559 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11560 added newline in the def file to keep MSC compiler satisfied
11562 * sdcc/src/z80/gen.c:
11563 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11564 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11565 - solved MSC error in function aopDump()
11567 * sdcc_vc.h: define PREFIX as "\\sdcc"
11569 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11570 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11572 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11573 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11574 - Rewrote the register banking algorithm.
11575 - Added pCode live-range analysis to registers (for now, only non-used and
11576 singly-used registers optimized away)
11578 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11580 * 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.
11582 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11583 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

11595 2002-04-15 Michael Hope <michaelh AT vroom>
11597 * device/lib/z80/printf.c (sprintf): Added.
11599 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11601 * src/z80/peeph.def: Added transpose redundent load rule.
11603 * src/z80/main.c: Added force callee saves for jaune.
