1547 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1549 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1550 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1552 One basic decision: e.g. src/clean.mk includes further files. In order
1553 to make this work there are two solutions:
1554 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1555 run configure on them. This way they can use
1556 'include $(srcdir)/port-clean.mk'
1557 - always include clean.mk by the Makefile at the same level. To avoid
1558 that `make clean` tries to include and build Makefile.dep the
1559 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1560 implemented, because now even `make uninstall` doesn't create
1561 Makefile.in. clean.mk could be eliminated by pasting it in
1564 * debugger/mcs51/Makefile.in: build own objects from library sources
1565 (SLIB, SDCC) in current directory
1567 * configure, configure.in: renamed --disable-device-lib-build in
1568 --disable-device-lib; added --enable-doc, the required tools are
1569 searched by configure; added result message; the toolchain for the
1570 belonging ports are now only built, if the port is enabled.
1572 * support/regression/*: all output is written in directory gen, because
1573 the fwk and ports directories don't livet in the build tree using vpath
1575 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1576 --disable-device-lib, added --enable-doc, added section VPATH
1578 * sim/ucsim/configure.in,
1579 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1580 z80 are enabled by default
1582 2006-04-24 Raphael Neider <rneider AT web.de>
1584 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1585 to config word, "pic14_"-prefixed some extern functions
1586 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1587 config word has been found
1588 * src/pic/device.h: added prototypes
1589 * src/pic/pcode.c: added "pic14_"-prefix where needed
1590 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1592 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1607 (pCodeRegOptimizeRegUsage): fixed typo in comment

1830 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1832 * src/mcs51/gen.c (genCall): fixed bug 1457608
1834 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1839 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1841 * src/SDCCpeeph.c (operandsLiteral): new, added,

1853 implemented patch 1120823 Thanks to Willy De la Court (normal
1854 interrupts need an interrupt number now if they are made critical),
1855 and enabled nesting of critical functions though not for gbz80
1856 (genCritical, genEndCritical): added functions
1857 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1858 * src/z80/mappings.i: added "ei" to all mappings

1863 submitted by the Debian SDCC maintainer Aurelien Jarno:
1864 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1865 archive with gcc 4.1 on mips and wrote the patch"
1867 2006-03-16 Raphael Neider <rneider AT web.de>
1869 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1870 the left operand is shorter than the result (c* = lit-c* + int),
1872 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1875 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1877 * src/.version: increased version number to 2.5.5
1878 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1879 linking is done manually in pic16 port's _linkEdit,
1880 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1881 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1882 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1883 allocate asmop as AOP_ACC,
1884 (aopForRemat): added parameter 'bool result' in function declaration,
1885 (pic16_aopGet): return AOP_ACC when accessing WREG,
1886 (pic16_popGetTempReg): minor modification,
1887 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1888 'pic16_allocWithIdx',

1890 calling function in absolute addresses,
1891 (genAssign): take into account AOP_ACC asmop,
1892 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1895 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1897 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1898 call to allocReg, not by manually allocating a new one,
1899 (pic16_assignRegisters): now before going through the register
1900 allocating functions mark all registers as free. This eliminates some
1901 side effects resulting from peephole parser done earlier in the backbone
1903 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1905 * src/SDCCicode.c (geniCodeLogic),

1924 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1925 (aopForSym, aopOp): increment asmop.allocated if reused,
1926 (freeAsmop): decrement asmop.allocated and check for zero instead of
1928 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1929 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1930 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1953 2006-03-06 Borut Razem <borut.razem AT siol.net>
1955 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1956 made the linker quiet

1960 * src/pic16/gen.c (genPcall): fixed bug #1443644
1961 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1962 which dumps before the function entry point a data byte which represents
1963 the number of the local variables used by the specified function, added
1964 'xinst' for initial support for Extended Instruction Support,
1965 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1966 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1967 port->fun_prefix anymore (may change later),
1968 (genFunction, genEndFunction): do not store/restore local registers for
1969 _main (this should take care the --main-return command line option in
1971 (genOr): removed some legacy pic-port instructions,
1972 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1973 performing operations with SFR's causes data to be written more than
1974 once to each SFR. Perhaps SFRs should be handled in special cases...
1975 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1977 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1978 into account for stack starting position,
1979 (struct OPTIONS pic16_optionsTable): added command line argument
1980 --extended or -y for Extended Instruction Support,
1981 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1982 (deassignLRs): *** perhaps the most important change, old 'for' code
1983 (commented out for reference), didn't account for some registers which
1984 were left marked 'not free' after a pointer operation. The change
1985 reduces register usage a lot in some cases
1987 2006-03-04 Borut Razem <borut.razem AT siol.net>

4317 * support/scripts/inc2h.pl: WIN32 port
4319 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4321 * device/lib/makefile.in: added abs.c and labs.c
4323 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4325 * device/include/stdint.h: added
4326 * device/lib/abs.c: added
4327 * device/lib/labs.c: added
4328 * device/include/stdlib.h: added abs() and labs() prototypes
4329 * device/lib/libsdcc.lib: added abs and labs
4330 * device/include/float.h,
4331 * device/lib/_fsmul.c,
4332 * device/lib/printf_fast.c,
4333 * device/lib/printf_tiny.c: updated comments
4335 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4337 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4340 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4342 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4343 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4345 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4347 * device/lib/printf_large.c: removed inline assembly for portability and
4348 readability. Use printf_fast if speed or size are more important.
4349 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4350 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4352 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4354 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4355 prevent compiler warning
4357 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4359 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4360 moved to level 0 and declared as static. Also they are explicit
4361 placed in access bank. This was necessery because some times they
4362 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4363 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4364 optimizations. Currently only compare to unsigned char is implemented,
4365 * src/pic16/gen.c: added fReturnIdx array,
4366 * (struct resolvedIfx) is moved to gen.h and made public,
4367 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4368 * (aopForSym): added an optimization to directly store in stack of
4369 the operand of a SEND iCode,
4370 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4371 but as registers instead (AOP_REG) using the fReturnIdx array,
4372 * (pic16_freeAsmop): remove the freed register from the
4373 _G.sregsAlloc field,
4374 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4375 a compare of 'WREG',
4376 * (pic16_popGetTempRegCond): changed function prototype, now
4377 function takes also a bitVector argument v which holds the current
4378 set of registers that are allocated for stack access by aopForSym,
4379 registers allocated in aopForSym for accessing stack symbols are not
4380 any more part of the functions usedRegs field,
4381 * (genCall): some times aopOp is called for a stack variable to be
4382 send, aopForSym might perform the push, if this is true make sure
4383 that genCall doesn't push the variable twice by testing _G.resDirect,
4384 * (genFunction): changed testing for unspecified interrupt number
4385 from 256 to INTNO_UNSPEC,
4386 * modified selection scheme of frame pointer generation. Previously
4387 if function did use local registers a frame pointer was generated,
4388 now a frame pointer is generated only if function has arguments
4389 (that need PLUSW2 register access), or has stack arguments, or the
4390 compiler is not instructed to omit the frame pointer,
4391 * (genEndFunction): before restoring local registers that were saved
4392 in the function preamble, also restore the registers that *might*
4393 have been allocated for stack access,
4394 * (genRet): removed some old comments,
4395 * (genCmp, the active (RN's) version): added a call to the
4396 pic16_genCmp_special function to perform the compare with a more
4397 robust and optimized way,
4398 * (genInline): a feature has been added in inline code generation,
4399 which allows a wildcard variable substitution when writing inline
4400 assembly. Code is incomplete and experimental therefore undocumented,
4401 * (genCast): changed order of aopOp for result and right to allow
4402 aopForSym to directly load the result if possible,
4403 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4404 perform an optimized compare on some selected special occasions,
4405 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4406 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4407 generate an IVT any more,
4408 * src/pic16/main.c (pic16_optionsTable): added command line option
4410 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4411 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4413 * src/pic16/NOTES: Raphael Neider added in list of active developers
4414 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4415 jumptable_end to prevent bug #,
4416 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4417 inCond and outCond fields,
4418 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4419 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4420 turn off register spilling,
4421 * (packRegsForOneUse): synced with other ports' versions although it
4422 is not used currently,
4423 * (pic16_packRegisters): added an optimization while reading
4424 structure bitfields, some registers may be saved (malloc code is
4425 decreased by 80 bytes)
4427 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4429 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4430 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4431 this can be optimized more?
4433 2005-03-10 Raphael Neider <rneider AT web.de>
4435 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4436 genNearPointerGet): (hopefully) fixed access to bitfields via
4437 pointers (p->bitN = x; and x = p->bitN; failed)
4439 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4441 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

5072 generated for switch statements. For now you need to set the
5073 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5074 Now 4 algorithms for mcs51 jumptable generation are used:
5075 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5109 * added libc directory. The current version of LibC contains string
5110 functions, ctype functions and macros and some functions of the
5111 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5112 be extensively tested in the future. Standard disclaimer here.
5113 Library is not automatically build yet. But one can build it by
5114 invoking 'make' inside the libc directory.

5125 * (pic16_storeForReturn): optimized return of 0,
5126 * (genCmp): experimental code for new genCmp which uses PIC18's
5127 special compare&skip instructions. Initial tests fail some times
5128 with variables grater than 1 byte in size, so new code is disabled,
5129 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5131 * (genCast): began a fix to optimize the casting of a bit to another
5132 bit, now assigning a bitfield to another bitfield will fail, sorry,

5141 and 1 for banking instruction,
5142 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5143 caused stop processing pCodes after a inline assembly block,

5146 registers when it shouldn't,
5147 * src/pic16/ralloc.c (allocReg): add preliminary support for
5148 supporting a limited set of temporary registers,
5150 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5174 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5176 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8155 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8157 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8158 loaded with the linker search paths (-L arguments) and the libraries
8159 to be linked with the current source (-l arguments). Changes
8160 currently will affect only the pic16 port.
8161 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8162 include path the port specific paths and port specific libraries,
8163 * gplink command now contains the $3 argument,
8164 * src/pic16/device.h,
8165 * src/pic16/device.c,: structure PIC_device is made public and
8166 renamed to PIC16_device, the same for variable Pics which is renamed

8181 Documenting changes from previous commits.
8182 * configure.in (version 1.56),
8183 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8184 when generating output files to configure the pic16 library,
8185 but now I've commented it out, since gputils aren't installed in the
8186 SF compile farm, so library won't compile
8188 * device/lib/Makefile.in (version 1.56): initially I've added in
8189 target 'all' the prerequestive 'model-pic16' so it compiled the
8190 pic16 library, but now I've commented it out for the same reasons
8192 * added targets 'model-pic16' and 'objects-pic16' to compile the
8194 * added target 'port-specific-objects-pic16' to handle the
8195 generated libraries and copy them into the build/ directory
8196 * added target 'clean-intermediate-pic16' to clean intermediate
8197 files into pic16 directory
8198 * in target 'installdirs' added line to create directory pic16 in
8199 the installation path

8202 added lines to copy all header files to installation path,
8203 * in target 'installdirs' added line create directory for pic16
8204 headers in the installation path

8219 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8220 option so that it actually works. Made it specific to the z80, since
8221 the gbz80 doesn't have these kinds of I/O ports.
8223 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8225 * device/include/z180.h,

8249 via literal number. The symbol is placed in the corresponding
8250 position of the data ram
8251 * (pic16_dump_section): relocatable and absolute uninitialized
8252 data are now emitted in sorted order to reduce section naming,
8253 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8254 weren't marked as being in the access bank,
8256 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8258 Added portion of GNU PIC Library under the directory
8259 device/include/pic16 and device/lib/pic16. These files
8260 contain the declarations of SFRs for the PIC18Fxx2 devices.
8261 The directory is initialized via configure from toplevel.
8263 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8291 all over. Telling LaTeX to be less strict with word spacing
8292 to better keep the right margin. Changed some notes about
8293 maintainance of the ports in section 3.2.1 - is it OK like this?

8304 processor registers declared internally by the port are emitted in
8305 the translation as equates,
8306 * src/pic16/gen.c: inline code is passed unprocessed to the
8308 * (pic16_popGetLit2): fnuction modified to take second operand as

8332 UPPER for immediate operands,
8333 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8335 * src/pic16/peeph.def: all peepholes with movff are commented out,
8336 because there is a problem in the pcode peep optimizer,
8337 * src/pic16/ralloc.c: the register allocator can now reuse local

8447 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8449 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8450 (default behaviour).
8452 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8454 A python script to validate compiler diagnostic messages. It can be
8455 used to verify that sdcc complains about bad c source code and
8456 gives a good location of the error.
8457 * support/valdiag/Makefile,
8458 * support/valdiag/valdiag.py,

8476 Bug reported from Jesus Calvino-Fraga
8478 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8480 * sdcc.spec: updated
8481 * device/include/Makefile.in: don't install CVS directories
8482 * device/lib/Makefile.in: added removal of CVS directories after install
8483 * doc/Makefile: fixed install, added local_icons
8484 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8485 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8486 * src/ds390/gen.c (genRightShift): fixed bug #870788
8487 * src/SDCCast.c (decorateType): fixed bug #870781
8489 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8491 PIC16 port related changes:
8492 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8493 added variable stackPos,
8495 * gen.c: genCall, assignResultValue: added support for
8496 pushing/retrieving function parameters to/from stack,
8497 genFunction,genEndFunction: setup stack frame for the
8499 genAddrOf: will be changed according to bug 863624
8501 * added files genutils.c and genutils.h which contain gen*
8502 debugged and optimised functions extracted from gen.c
8504 * glue.c: added variable 'externs' which holds extern symbols,
8505 pic16emitRegularMap: is modified to properly handle relocatable
8506 symbols under the new scheme,
8507 pic16createInterruptVect: is modified
8508 pic16printPublics: is modified to emit 'global' assembler directives,
8509 added pic16_printExterns to print extern symbols,
8510 pic16glue: initializes stack/frame pointer in the beginning of
8511 the assembly output. Temporary hack, will be corrected later,
8512 because gplink yet does not support stack and SDCC does not
8513 yet support a type of crt0.o object to create the final binary.
8515 * Removed many lines that contain 8051 legacy code.
8516 * The code is finally placed under a 'code' directive.
8517 * Added port specific options.
8519 * _process_pragma: simplified since now we do not need *special*
8520 include file to define SFR registers. But a separate header
8521 will be needed. This will be developed later.
8522 * _pic16_parseOptions: added, parses port specific options:
8523 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8524 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8525 --preplace-udata-with=
8527 * _pic16_setDefaultOptions: modified to initialize section names,
8528 but hack is temporarly out of order since it needs improvement.
8529 * _pic16_genAssemblerPreamble: configuration words are emitted by
8530 their address instead of their name. This part is incomplete and
8531 supports only the 18Fxx2 devices. Other devices will emit an error
8532 during assembly since they do not contain the same set of config
8534 * _pic16_genIVT: is modified,
8536 * pcode.c: added definitions for some hardware registers that are needed
8538 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8539 All PCI entries are updated. Now LFSR is supported.
8540 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8541 * added pic16_newpCodeOpLit2 to support instructions with
8542 two literal arguments
8543 * pic16_pCode2str: corrected code that emits assembler instructions
8544 with two literal operands and those that have an access bit modifier
8545 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8546 this fixes a bug which caused some labels to be lost, when an
8547 assembler directive was added, i.e. banksel,
8548 * pic16_FixRegisterBanking: improved logic that causes the insertion
8550 * InlineFunction: functions that are called once, are not any more
8551 inlined. This can be a port option in the future,
8553 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8555 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8556 hold the corresponding uninitialized symbols,
8557 * pic16_allocProcessorRegister: registers have explicit marked the
8559 * pic16_allocInternalRegister: registers are explicit marked as
8561 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8562 processing list, so bit registers were lost,
8565 * ralloc.h: added field 'accessBank' and original symbol operand
8566 in register definition,
8567 * removed the field isMapped from register definition,
8569 ** Several functions have been removed from various sources:
8570 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8571 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8572 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8573 pic16_assignRelocatableRegisters
8575 ** others have been introduced:
8576 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8577 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8579 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8581 * support/scripts/inc2h.pl: changed definition of BIT_AT
8582 to emit 'sbit at' instead of 'bit at'. This was a request.
8584 PIC16 port related preliminary changes:
8585 * gen.c: prefixed function popRegFromString with
8586 pic16_ and all references to it corrected
8587 * pcode.c: all pic16_pc_* hardware registers prefixed
8588 with underscore (_),
8589 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8590 * ralloc.c: newReg(): when register is REG_SFR then
8591 set address to rIdx,
8592 pic16_allocProcessorRegister(): marks register wasUsed=0
8593 pic16_writeUsedRegs(): added a call to assign processor
8594 registers via pic16_assignFixedRegisters
8596 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8598 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8599 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8600 variables in unused register banks. Also the SSEG is placed
8601 wherever there is enough space for it, and IDATA can be anywhere
8602 in internal RAM. For now compile using -Wl-Y[stack_size].
8603 The mem file is different for this option as well, since it
8604 makes no sense of talking about DSEG lenght.
8606 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8608 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8609 in certain cases, e.g. when ROM assignment, patch provided
8610 from Albert den Haan.
8612 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8753 xdata and data memory on startup. Set the environment variable
8754 SDCC_NOGENRAMCLEAR to disable this.
8755 * src/mcs51/peephole.def,
8756 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8757 (allows non-interrupt and interrupt code to safely compete for a resource

9499 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9500 to xdata int at 0x1234 tempvar = 1.
9501 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9502 provided by Akiya ISHIDA

9518 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9520 Fixed bug #621531 (const & volatile confusion in the type chain).
9521 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9601 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9602 iCode properly now. Use getSize instead of nRegs since a & b
9603 aren't part of the nRegs tally.
9605 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9607 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

9613 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9614 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9615 fetching of the pointer
9616 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9617 copied from genNearPointerSet()
9618 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9619 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9620 If they pop r0/r1 they must be called in the opposite order than aopOp().
9621 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9622 (resp. --stack-auto), prepared for --xstack

9631 these ports have their own __sdcc_external_start()
9633 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9635 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9636 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9637 type for bits was changed. It resulted in bit variables becoming
9638 global, which is not permitted in PIC 14 assembly output.
9640 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9642 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9655 A few small changes that speed up the peephole optimizer.
9659 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9661 Try to make the peephole optimizer smarter by maintaining
9662 an association between the assembly source code and the
9663 iCodes that originated them. Put this information to use
9664 with a new peephole rule condition "notVolatile" so that
9665 the rules can be aggressive yet still safe.
9670 * src/mcs51/peeph.def
9672 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9676 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9677 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9678 if the left or right operand symbols have the accuse flag set.
9680 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9682 Changed the type of the result of the ! (NOT) operator to char;
9683 previously it returned the same type as the source. This allows
9684 us to eliminate all the genFloatNot functions (all of its target
9685 implementations were very buggy) since !float can use the same
9688 * src/SDCCicode.c (ast2iCode): ! returns char

9695 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9697 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9698 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9699 during interrupts. Ensure WSAVE is located at a shared bank address.
9700 2. Fixed page selection in some places
9701 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9702 the registers name strings.
9703 4. Fixed "signed / unsigned compare" compiler warnings.
9704 5. The PIC port manages its own allocation of the general purpose
9705 registers, but makes no attempt to reuse them. As a result when
9706 compiling it soon runs out of general purpose registers. Some
9707 additional code was added to the files pcode.c and device.c to walk
9708 through the function call tree and rename the registers so that they
9718 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9719 genPlus() & genMinus() when the result is the same as left or right
9721 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9725 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9727 Made bitfield a distinct type from bit so that bitfields
9728 convert as per ANSI C and bits retain their traditional
9729 boolean style behaviour. Implemented bitfield support in
9737 * src/ds390/gen.c: bit v bitfield split
9738 * src/z80/gen.c: New support for bitfields
9739 * support/regression/tests/bitfields.c: reenabled z80,
9742 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9744 Rules 246.x, 247.x relate to bitfields, the others speed up
9745 access to xdata mapped I/O devices.
9747 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9749 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9751 Cleaned up genPackBits and genUnpackBits and added two helper
9752 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9753 for literal assignments in genPackBits (thanks to Frieder for
9759 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9761 Fixed bug #748310 (pointer to function type mishandled when the
9762 function name is omitted). Also fixed a SIGSEGV when a function
9763 attribute (reentrant, etc) is used on a non-function or on a
9764 function but misplaced before the parameter list.
9766 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9768 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9769 * support/Util/SDCCerr.h,
9770 * support/Util/SDCCerr.c: Added func attr misuse error msg
9772 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9774 Fixed bug #787649 by anonymous
9775 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9776 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9778 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9791 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9793 Made the constant following the "interrupt" keyword optional. If
9794 omitted, the function will not automatically be given an entry
9795 in the interrupt vector table (similar to #pragma NOIV, but
9796 less syntacticly kludgy). The interrupt number is also now
9797 range checked. Also fixed a bug in the high order bit example

9808 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9810 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type

10328 messages from optionsTable when a port is not configured, added
10329 support for the PIc16 port in the ports table, when executing
10330 the compiler with no port specified on command line, a default
10331 port is selected with the new macro DEFAULT_PORT which is
10332 defined in port.h, in setDefaultOptions() linkOptions is removed
10333 from initialization assignment, since now it is a set,
10334 parseCmdLine uses setParseWithComma for linkOptions, in
10335 linkEdit() linkOptions are accessed with new function indexSet()
10336 which returns the i'th item of a set variable. See SDCCset.c, in
10337 linkEdit() when calling buildCmdLine(), added linkOptions as
10338 last argument. Now users can pass arguments to gplink via the

11399 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11400 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11410 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11411 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11417 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11418 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11420 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11421 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11423 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11425 * in /sdcc/as/mcs51/ changed these files in order to create an
11426 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11427 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11428 following files to include the previous two files: aslink.dsp,
11429 Makefile.aslink, Makefile.bcc, and Makefile.in.
11431 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11432 .adb instead of .cdb
11434 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11436 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11437 value from option --iram-size.
11439 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11441 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11444 2002-09-18 <wiml AT hhhh.org>
11446 * SDCClrange.h: exposed setFromRange() and setToRange()
11447 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11448 packRegsForAccUse() (bug 542397)
11449 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11450 multiple times and emitting the fetch operations more than once
11451 added aopGetUsesAcc() function to allow binary operators to
11452 fetch their operands in the correct order; made genMinus() emit
11453 compact code for X = LITERAL - Y
11455 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11456 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11457 sprintf() in line 1267.
11459 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11460 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11463 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11464 Changes to aslink (All the changes are marked with 'JCF'):
11466 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11469 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11470 area BSEG. Also moves, if possible, the DATA area down into the internal
11471 ram so more space is available.
11473 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11476 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11477 not bytes. Function summary() which creates a memory usage summary
11478 file with extension .mem. Reports of overlaping stack and small stack
11479 size. If the space for the stack is less than 16 bytes aslink trows a
11482 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11483 the 8051. Option 'y' for memory summary output file.
11485 Changes to sdcc (All the changes are marked with 'JCF'):
11487 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11489 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11490 overlaying area for it (uses RegBankUsed[4]).
11492 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11493 bank zero as used by default. By default aslink locates the stack
11494 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11495 the creation of the .mem file. Delegates the allocation of data area
11496 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11497 the begining of the stack area to aslink.
11499 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11500 glue() in SDCCglue.c creates an area for it.
11502 2002-09-03 Borut Razem <borut.razem AT siol.net>
11503 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11504 sdcc/src/pic/glue.c:
11505 introduced atexit() handler for teporay files removal in case of
11506 errors, assertions, ...
11508 2002-08-29 Borut Razem <borut.razem AT siol.net>
11509 * sdcc/support/cpp2/auto-host_vc_in.h:
11510 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11511 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11512 Maybe there is a similar problem with BORLANDC? It should be checked!
11514 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11515 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11516 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11517 was not executed, and the compiler (cl) launched a warning:
11518 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11520 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11521 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11523 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11524 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11526 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11527 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11528 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11529 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11530 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11531 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11532 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11533 - added Release configuration in VS projects
11534 - review of compiler an linker options
11535 - VC .exe files are generated in bin_vc directory, not to interfere
11536 with binaries generated from other projects (cygwin, mingw, bcc ...)
11538 * sdcc/src/yacc.dsp: added
11540 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11541 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11542 and insert the version number definitions from .version
11544 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11546 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11547 added - genarate auto-host.h using auto-host_vc_in.h as template
11550 removed from CVS, generated automatically
11552 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11553 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11555 2002-08-11 Borut Razem <borut.razem AT siol.net>
11556 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11558 2002-08-10 Borut Razem <borut.razem AT siol.net>
11559 * src/SDCCmain.c (main):
11560 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11561 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11562 The consequence was that some temporary files were not removed.
11565 unification of code in functions tempfilename() and tempfile():
11566 function tempnam() is defined in Visual Studio 6.0 and .NET
11568 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11570 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11571 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11572 - removed compiler command line option /WX: Treats all warnings as errors
11573 - update a list of source files, included into the project
11575 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11576 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11577 changed project type to Generic Project so that can be correcly converted to VS.NET project
11579 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11581 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11583 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11585 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11586 added return 0 statements after assert() to make compiler happy
11588 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11589 added newline in the def file to keep MSC compiler satisfied
11591 * sdcc/src/z80/gen.c:
11592 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11593 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11594 - solved MSC error in function aopDump()
11596 * sdcc_vc.h: define PREFIX as "\\sdcc"
11598 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11599 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11601 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11602 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11603 - Rewrote the register banking algorithm.
