1434 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1436 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1437 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1439 One basic decision: e.g. src/clean.mk includes further files. In order
1440 to make this work there are two solutions:
1441 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1442 run configure on them. This way they can use
1443 'include $(srcdir)/port-clean.mk'
1444 - always include clean.mk by the Makefile at the same level. To avoid
1445 that `make clean` tries to include and build Makefile.dep the
1446 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1447 implemented, because now even `make uninstall` doesn't create
1448 Makefile.in. clean.mk could be eliminated by pasting it in
1451 * debugger/mcs51/Makefile.in: build own objects from library sources
1452 (SLIB, SDCC) in current directory
1454 * configure, configure.in: renamed --disable-device-lib-build in
1455 --disable-device-lib; added --enable-doc, the required tools are
1456 searched by configure; added result message; the toolchain for the
1457 belonging ports are now only built, if the port is enabled.
1459 * support/regression/*: all output is written in directory gen, because
1460 the fwk and ports directories don't livet in the build tree using vpath
1462 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1463 --disable-device-lib, added --enable-doc, added section VPATH
1465 * sim/ucsim/configure.in,
1466 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1467 z80 are enabled by default
1469 2006-04-24 Raphael Neider <rneider AT web.de>
1471 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1472 to config word, "pic14_"-prefixed some extern functions
1473 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1474 config word has been found
1475 * src/pic/device.h: added prototypes
1476 * src/pic/pcode.c: added "pic14_"-prefix where needed
1477 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1479 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1487 * doc/Makefile: sync with nightly build makefile
1489 2006-04-24 Raphael Neider <rneider AT web.de>
1491 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1492 registers that have not been assigned proper liveranges,
1493 fixes #1469504 and #1474602,
1494 (pCodeRegOptimizeRegUsage): fixed typo in comment
1496 2006-04-24 Borut Razem <borut.razem AT siol.net>
1498 * device/examples/main8051.c: deleted - it was removed from CVS

1743 (genCritical, genEndCritical): added functions
1744 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1745 * src/z80/mappings.i: added "ei" to all mappings

1757 the left operand is shorter than the result (c* = lit-c* + int),
1759 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1762 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1764 * src/.version: increased version number to 2.5.5
1765 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1766 linking is done manually in pic16 port's _linkEdit,
1767 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1768 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1769 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1770 allocate asmop as AOP_ACC,
1771 (aopForRemat): added parameter 'bool result' in function declaration,
1772 (pic16_aopGet): return AOP_ACC when accessing WREG,

1784 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1785 call to allocReg, not by manually allocating a new one,
1786 (pic16_assignRegisters): now before going through the register

1838 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1840 2006-03-06 Borut Razem <borut.razem AT siol.net>
1842 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1843 made the linker quiet
1845 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1847 * src/pic16/gen.c (genPcall): fixed bug #1443644
1848 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1849 which dumps before the function entry point a data byte which represents
1850 the number of the local variables used by the specified function, added
1851 'xinst' for initial support for Extended Instruction Support,
1852 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1853 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1854 port->fun_prefix anymore (may change later),
1855 (genFunction, genEndFunction): do not store/restore local registers for
1856 _main (this should take care the --main-return command line option in
1858 (genOr): removed some legacy pic-port instructions,
1859 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1860 performing operations with SFR's causes data to be written more than

1869 (deassignLRs): *** perhaps the most important change, old 'for' code
1870 (commented out for reference), didn't account for some registers which
1871 were left marked 'not free' after a pointer operation. The change
1872 reduces register usage a lot in some cases

4147 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4148 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4149 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4150 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4151 always available in leading double underscore form. The C99 support is

4230 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4232 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4234 * device/lib/printf_large.c: removed inline assembly for portability and
4235 readability. Use printf_fast if speed or size are more important.
4236 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4237 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4239 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4241 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4242 prevent compiler warning
4244 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4246 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4247 moved to level 0 and declared as static. Also they are explicit
4248 placed in access bank. This was necessery because some times they
4249 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4250 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4251 optimizations. Currently only compare to unsigned char is implemented,
4252 * src/pic16/gen.c: added fReturnIdx array,
4253 * (struct resolvedIfx) is moved to gen.h and made public,
4254 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4255 * (aopForSym): added an optimization to directly store in stack of
4256 the operand of a SEND iCode,
4257 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4258 but as registers instead (AOP_REG) using the fReturnIdx array,
4259 * (pic16_freeAsmop): remove the freed register from the
4260 _G.sregsAlloc field,
4261 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4262 a compare of 'WREG',
4263 * (pic16_popGetTempRegCond): changed function prototype, now
4264 function takes also a bitVector argument v which holds the current
4265 set of registers that are allocated for stack access by aopForSym,
4266 registers allocated in aopForSym for accessing stack symbols are not
4267 any more part of the functions usedRegs field,
4268 * (genCall): some times aopOp is called for a stack variable to be
4269 send, aopForSym might perform the push, if this is true make sure
4270 that genCall doesn't push the variable twice by testing _G.resDirect,
4271 * (genFunction): changed testing for unspecified interrupt number
4272 from 256 to INTNO_UNSPEC,
4273 * modified selection scheme of frame pointer generation. Previously
4274 if function did use local registers a frame pointer was generated,
4275 now a frame pointer is generated only if function has arguments
4276 (that need PLUSW2 register access), or has stack arguments, or the
4277 compiler is not instructed to omit the frame pointer,
4278 * (genEndFunction): before restoring local registers that were saved
4279 in the function preamble, also restore the registers that *might*
4280 have been allocated for stack access,
4281 * (genRet): removed some old comments,
4282 * (genCmp, the active (RN's) version): added a call to the
4283 pic16_genCmp_special function to perform the compare with a more
4284 robust and optimized way,
4285 * (genInline): a feature has been added in inline code generation,
4286 which allows a wildcard variable substitution when writing inline
4287 assembly. Code is incomplete and experimental therefore undocumented,
4288 * (genCast): changed order of aopOp for result and right to allow
4289 aopForSym to directly load the result if possible,
4290 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4291 perform an optimized compare on some selected special occasions,
4292 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4293 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4294 generate an IVT any more,
4295 * src/pic16/main.c (pic16_optionsTable): added command line option
4297 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4298 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4300 * src/pic16/NOTES: Raphael Neider added in list of active developers
4301 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4302 jumptable_end to prevent bug #,
4303 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4304 inCond and outCond fields,
4305 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4306 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4307 turn off register spilling,
4308 * (packRegsForOneUse): synced with other ports' versions although it
4309 is not used currently,
4310 * (pic16_packRegisters): added an optimization while reading
4311 structure bitfields, some registers may be saved (malloc code is
4312 decreased by 80 bytes)
4314 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4316 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4317 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4318 this can be optimized more?

4959 generated for switch statements. For now you need to set the
4960 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4961 Now 4 algorithms for mcs51 jumptable generation are used:
4962 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4963 addresses loaded pc-relative for up to 112 cases and stack-pushing

4996 * added libc directory. The current version of LibC contains string
4997 functions, ctype functions and macros and some functions of the
4998 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4999 be extensively tested in the future. Standard disclaimer here.
5000 Library is not automatically build yet. But one can build it by

5012 * (pic16_storeForReturn): optimized return of 0,
5013 * (genCmp): experimental code for new genCmp which uses PIC18's
5014 special compare&skip instructions. Initial tests fail some times
5015 with variables grater than 1 byte in size, so new code is disabled,
5016 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5018 * (genCast): began a fix to optimize the casting of a bit to another
5019 bit, now assigning a bitfield to another bitfield will fail, sorry,

8045 loaded with the linker search paths (-L arguments) and the libraries
8046 to be linked with the current source (-l arguments). Changes
8047 currently will affect only the pic16 port.
8048 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8049 include path the port specific paths and port specific libraries,
8050 * gplink command now contains the $3 argument,

8068 Documenting changes from previous commits.
8069 * configure.in (version 1.56),
8070 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8071 when generating output files to configure the pic16 library,
8072 but now I've commented it out, since gputils aren't installed in the
8073 SF compile farm, so library won't compile
8075 * device/lib/Makefile.in (version 1.56): initially I've added in
8076 target 'all' the prerequestive 'model-pic16' so it compiled the
8077 pic16 library, but now I've commented it out for the same reasons
8079 * added targets 'model-pic16' and 'objects-pic16' to compile the
8081 * added target 'port-specific-objects-pic16' to handle the
8082 generated libraries and copy them into the build/ directory
8083 * added target 'clean-intermediate-pic16' to clean intermediate
8084 files into pic16 directory
8085 * in target 'installdirs' added line to create directory pic16 in

8089 added lines to copy all header files to installation path,
8090 * in target 'installdirs' added line create directory for pic16
8091 headers in the installation path

8325 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8327 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
8329 * support/valdiag/tests/overflow.c: added
8330 * src/SDCCast.c (decorateType),
8331 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8332 LEFT_OP (left shift)
8334 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8336 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8337 (default behaviour).
8339 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8341 A python script to validate compiler diagnostic messages. It can be
8342 used to verify that sdcc complains about bad c source code and
8343 gives a good location of the error.
8344 * support/valdiag/Makefile,
8345 * support/valdiag/valdiag.py,
8346 * support/valdiag/tests/*
8348 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8350 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8351 * src/SDCCsymt.c (newEnumType),
8353 * support/Util/SDCCerr.c,
8354 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
8356 * support/regression/tests/enum.c: added test for enum values that
8357 require at least 2 bytes of storage.
8359 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8361 * src/common.h: added ifndef/define/endif macros
8362 around the header file.
8363 Bug reported from Jesus Calvino-Fraga
8365 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8367 * sdcc.spec: updated
8368 * device/include/Makefile.in: don't install CVS directories
8369 * device/lib/Makefile.in: added removal of CVS directories after install
8370 * doc/Makefile: fixed install, added local_icons
8371 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8372 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8373 * src/ds390/gen.c (genRightShift): fixed bug #870788
8374 * src/SDCCast.c (decorateType): fixed bug #870781
8376 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8378 PIC16 port related changes:
8379 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8380 added variable stackPos,
8382 * gen.c: genCall, assignResultValue: added support for
8383 pushing/retrieving function parameters to/from stack,
8384 genFunction,genEndFunction: setup stack frame for the
8386 genAddrOf: will be changed according to bug 863624
8388 * added files genutils.c and genutils.h which contain gen*
8389 debugged and optimised functions extracted from gen.c
8391 * glue.c: added variable 'externs' which holds extern symbols,
8392 pic16emitRegularMap: is modified to properly handle relocatable
8393 symbols under the new scheme,
8394 pic16createInterruptVect: is modified
8395 pic16printPublics: is modified to emit 'global' assembler directives,
8396 added pic16_printExterns to print extern symbols,
8397 pic16glue: initializes stack/frame pointer in the beginning of
8398 the assembly output. Temporary hack, will be corrected later,
8399 because gplink yet does not support stack and SDCC does not
8400 yet support a type of crt0.o object to create the final binary.
8402 * Removed many lines that contain 8051 legacy code.
8403 * The code is finally placed under a 'code' directive.
8404 * Added port specific options.
8406 * _process_pragma: simplified since now we do not need *special*
8407 include file to define SFR registers. But a separate header
8408 will be needed. This will be developed later.
8409 * _pic16_parseOptions: added, parses port specific options:
8410 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8411 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8412 --preplace-udata-with=
8414 * _pic16_setDefaultOptions: modified to initialize section names,
8415 but hack is temporarly out of order since it needs improvement.
8416 * _pic16_genAssemblerPreamble: configuration words are emitted by
8417 their address instead of their name. This part is incomplete and
8418 supports only the 18Fxx2 devices. Other devices will emit an error
8419 during assembly since they do not contain the same set of config
8421 * _pic16_genIVT: is modified,
8423 * pcode.c: added definitions for some hardware registers that are needed
8425 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8426 All PCI entries are updated. Now LFSR is supported.
8427 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8428 * added pic16_newpCodeOpLit2 to support instructions with
8429 two literal arguments
8430 * pic16_pCode2str: corrected code that emits assembler instructions
8431 with two literal operands and those that have an access bit modifier
8432 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8433 this fixes a bug which caused some labels to be lost, when an
8434 assembler directive was added, i.e. banksel,
8435 * pic16_FixRegisterBanking: improved logic that causes the insertion
8437 * InlineFunction: functions that are called once, are not any more
8438 inlined. This can be a port option in the future,
8440 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8442 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8443 hold the corresponding uninitialized symbols,
8444 * pic16_allocProcessorRegister: registers have explicit marked the
8446 * pic16_allocInternalRegister: registers are explicit marked as
8448 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8449 processing list, so bit registers were lost,
8452 * ralloc.h: added field 'accessBank' and original symbol operand
8453 in register definition,
8454 * removed the field isMapped from register definition,
8456 ** Several functions have been removed from various sources:
8457 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8458 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8459 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8460 pic16_assignRelocatableRegisters
8462 ** others have been introduced:
8463 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8464 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8466 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8468 * support/scripts/inc2h.pl: changed definition of BIT_AT
8469 to emit 'sbit at' instead of 'bit at'. This was a request.
8471 PIC16 port related preliminary changes:
8472 * gen.c: prefixed function popRegFromString with
8473 pic16_ and all references to it corrected
8474 * pcode.c: all pic16_pc_* hardware registers prefixed
8475 with underscore (_),
8476 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8477 * ralloc.c: newReg(): when register is REG_SFR then
8478 set address to rIdx,
8479 pic16_allocProcessorRegister(): marks register wasUsed=0
8480 pic16_writeUsedRegs(): added a call to assign processor
8481 registers via pic16_assignFixedRegisters
8483 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8485 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8486 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8487 variables in unused register banks. Also the SSEG is placed
8488 wherever there is enough space for it, and IDATA can be anywhere
8489 in internal RAM. For now compile using -Wl-Y[stack_size].
8490 The mem file is different for this option as well, since it
8491 makes no sense of talking about DSEG lenght.
8493 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8495 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8496 in certain cases, e.g. when ROM assignment, patch provided
8497 from Albert den Haan.
8499 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8642 * src/mcs51/peephole.def,
8643 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8655 multiply defined with mismatching "at" address.
8657 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8659 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

8738 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8740 * src/SDCCast.c (decorateType): disabled a transformation I added in
8741 revision 1.188 (access to fields of a structure at an absolute address);
8742 it breaks with bitfields, extern declarations, and gcse analysis.
8743 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8744 could be assigned through a pointer, so don't complain.
8745 * src/SDCCast.c (astErrors),
8747 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9327 genCodePointerGet, genGenPointerGet, genFarPointerSet,
9328 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
9329 (ralloc doesn't intentionally do this now, but perhaps later)
9330 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
9331 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

9382 * src/SDCCsymt.c (sclsFromPtr),
9384 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9385 support for standard C idiom of memory mapped variables; for
9386 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9387 to xdata int at 0x1234 tempvar = 1.
9388 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9389 provided by Akiya ISHIDA

9405 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9407 Fixed bug #621531 (const & volatile confusion in the type chain).
9408 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9409 refer to the const or volatile state of the pointer itself.

9474 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9475 pcoderegs.h, ralloc.c, ralloc.h
9476 * main.c: added top header and GPL license notice
9477 * pcode.c: fixed the if-conditional warning
9479 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>

9500 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9501 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9502 fetching of the pointer
9503 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9504 copied from genNearPointerSet()
9505 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9506 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9507 If they pop r0/r1 they must be called in the opposite order than aopOp().
9508 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9509 (resp. --stack-auto), prepared for --xstack

9520 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9522 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9523 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9524 type for bits was changed. It resulted in bit variables becoming
9525 global, which is not permitted in PIC 14 assembly output.
9527 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9529 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9531 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9533 Z80 and MCS51 linkers complaint if a public symbol is defined

9542 A few small changes that speed up the peephole optimizer.
9546 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9548 Try to make the peephole optimizer smarter by maintaining
9549 an association between the assembly source code and the
9550 iCodes that originated them. Put this information to use
9551 with a new peephole rule condition "notVolatile" so that
9552 the rules can be aggressive yet still safe.
9557 * src/mcs51/peeph.def
9559 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9563 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9564 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9565 if the left or right operand symbols have the accuse flag set.
9567 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9569 Changed the type of the result of the ! (NOT) operator to char;
9570 previously it returned the same type as the source. This allows
9571 us to eliminate all the genFloatNot functions (all of its target
9572 implementations were very buggy) since !float can use the same
9575 * src/SDCCicode.c (ast2iCode): ! returns char

9582 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9584 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9585 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9586 during interrupts. Ensure WSAVE is located at a shared bank address.
9587 2. Fixed page selection in some places
9588 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9589 the registers name strings.
9590 4. Fixed "signed / unsigned compare" compiler warnings.
9591 5. The PIC port manages its own allocation of the general purpose
9592 registers, but makes no attempt to reuse them. As a result when
9593 compiling it soon runs out of general purpose registers. Some
9594 additional code was added to the files pcode.c and device.c to walk
9595 through the function call tree and rename the registers so that they
9605 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9606 genPlus() & genMinus() when the result is the same as left or right
9608 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9612 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9614 Made bitfield a distinct type from bit so that bitfields
9615 convert as per ANSI C and bits retain their traditional
9616 boolean style behaviour. Implemented bitfield support in
9624 * src/ds390/gen.c: bit v bitfield split
9625 * src/z80/gen.c: New support for bitfields
9626 * support/regression/tests/bitfields.c: reenabled z80,
9629 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9631 Rules 246.x, 247.x relate to bitfields, the others speed up
9632 access to xdata mapped I/O devices.
9634 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9636 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9638 Cleaned up genPackBits and genUnpackBits and added two helper
9639 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9640 for literal assignments in genPackBits (thanks to Frieder for
9646 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9648 Fixed bug #748310 (pointer to function type mishandled when the
9649 function name is omitted). Also fixed a SIGSEGV when a function
9650 attribute (reentrant, etc) is used on a non-function or on a
9651 function but misplaced before the parameter list.
9653 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9655 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9656 * support/Util/SDCCerr.h,
9657 * support/Util/SDCCerr.c: Added func attr misuse error msg

9678 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9680 Made the constant following the "interrupt" keyword optional. If
9681 omitted, the function will not automatically be given an entry
9682 in the interrupt vector table (similar to #pragma NOIV, but
9683 less syntacticly kludgy). The interrupt number is also now
9684 range checked. Also fixed a bug in the high order bit example

9698 * src/SDCCicode.c (operandOperation): rewritten some ops
9699 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9700 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9702 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9703 be re-activated by defining REDUCE_LITERALS)
9704 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9705 unsigned, but are signed by default
9706 * src/SDCCval.c (constVal): rearranged
9707 * src/SDCCval.c (valMod): preliminary fix
9708 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9750 constants are unsigned; added recognition of "u" flag for unsigned
9751 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9752 * src/SDCCval.c (valDiv, valMod): fixed signdness
9753 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9754 signedness of modulo, left and right shift

10215 messages from optionsTable when a port is not configured, added
10216 support for the PIc16 port in the ports table, when executing
10217 the compiler with no port specified on command line, a default
10218 port is selected with the new macro DEFAULT_PORT which is
10219 defined in port.h, in setDefaultOptions() linkOptions is removed
10220 from initialization assignment, since now it is a set,
10221 parseCmdLine uses setParseWithComma for linkOptions, in
10222 linkEdit() linkOptions are accessed with new function indexSet()
10223 which returns the i'th item of a set variable. See SDCCset.c, in
10224 linkEdit() when calling buildCmdLine(), added linkOptions as
10225 last argument. Now users can pass arguments to gplink via the
10226 -Wl option, main() uses pic16glue() to glue up pic16 programs

10240 gpasm complaining and test the linkage with gplink, _linkCmd and
10241 _asmCmd changed to be more gplink and gpasm friendly
10242 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10243 produced an error when parsed, peep rule 12 is added to utilize
10244 movff, but it is commented out since the pCode does not support
10245 yet a command with 2 address arguments

11307 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11308 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11310 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11312 * in /sdcc/as/mcs51/ changed these files in order to create an
11313 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11314 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11315 following files to include the previous two files: aslink.dsp,
11316 Makefile.aslink, Makefile.bcc, and Makefile.in.
11318 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11319 .adb instead of .cdb
11321 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11323 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11324 value from option --iram-size.
11326 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11328 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11331 2002-09-18 <wiml AT hhhh.org>
11333 * SDCClrange.h: exposed setFromRange() and setToRange()
11334 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11335 packRegsForAccUse() (bug 542397)
11336 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11337 multiple times and emitting the fetch operations more than once
11338 added aopGetUsesAcc() function to allow binary operators to
11339 fetch their operands in the correct order; made genMinus() emit
11340 compact code for X = LITERAL - Y
11342 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11343 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11344 sprintf() in line 1267.
11346 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11347 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11350 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11351 Changes to aslink (All the changes are marked with 'JCF'):
11353 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11356 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11357 area BSEG. Also moves, if possible, the DATA area down into the internal
11358 ram so more space is available.
11360 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11363 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11364 not bytes. Function summary() which creates a memory usage summary
11365 file with extension .mem. Reports of overlaping stack and small stack
11366 size. If the space for the stack is less than 16 bytes aslink trows a
11369 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11370 the 8051. Option 'y' for memory summary output file.
11372 Changes to sdcc (All the changes are marked with 'JCF'):
11374 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11376 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11377 overlaying area for it (uses RegBankUsed[4]).
11379 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11380 bank zero as used by default. By default aslink locates the stack
11381 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11382 the creation of the .mem file. Delegates the allocation of data area
11383 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11384 the begining of the stack area to aslink.
11386 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11387 glue() in SDCCglue.c creates an area for it.
11389 2002-09-03 Borut Razem <borut.razem AT siol.net>
11390 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11391 sdcc/src/pic/glue.c:
11392 introduced atexit() handler for teporay files removal in case of
11393 errors, assertions, ...
11395 2002-08-29 Borut Razem <borut.razem AT siol.net>
11396 * sdcc/support/cpp2/auto-host_vc_in.h:
11397 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11398 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11399 Maybe there is a similar problem with BORLANDC? It should be checked!
11401 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11402 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11403 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11404 was not executed, and the compiler (cl) launched a warning:
11405 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11407 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11408 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11410 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11411 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11413 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11414 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11415 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11416 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11417 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11418 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11419 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11420 - added Release configuration in VS projects
11421 - review of compiler an linker options
11422 - VC .exe files are generated in bin_vc directory, not to interfere
11423 with binaries generated from other projects (cygwin, mingw, bcc ...)
11425 * sdcc/src/yacc.dsp: added
11427 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11428 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11429 and insert the version number definitions from .version
11431 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11433 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11434 added - genarate auto-host.h using auto-host_vc_in.h as template
11437 removed from CVS, generated automatically
11439 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11440 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11442 2002-08-11 Borut Razem <borut.razem AT siol.net>
11443 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11445 2002-08-10 Borut Razem <borut.razem AT siol.net>
11446 * src/SDCCmain.c (main):
11447 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11448 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11449 The consequence was that some temporary files were not removed.
11452 unification of code in functions tempfilename() and tempfile():
11453 function tempnam() is defined in Visual Studio 6.0 and .NET
11455 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11457 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11458 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11459 - removed compiler command line option /WX: Treats all warnings as errors
11460 - update a list of source files, included into the project
11462 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11463 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11464 changed project type to Generic Project so that can be correcly converted to VS.NET project
11466 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11468 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11470 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11472 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11473 added return 0 statements after assert() to make compiler happy
11475 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11476 added newline in the def file to keep MSC compiler satisfied
11478 * sdcc/src/z80/gen.c:
11479 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11480 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11481 - solved MSC error in function aopDump()
11483 * sdcc_vc.h: define PREFIX as "\\sdcc"
11485 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11486 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11489 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11490 - Rewrote the register banking algorithm.
11491 - Added pCode live-range analysis to registers (for now, only non-used and
11492 singly-used registers optimized away)
11494 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11496 * 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.

11525 2002-03-28 Johan Knol <johan AT balder>
11527 * src/SDCCval.c: fixed bug #532436
11529 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11531 Added "char *Processor" field to the port structure.
11534 Added -p option. Allows port dependent processor to be specified.
11537 Initialized the new field char *Processor field to NULL in all ports
11540 Compiler generated registers for interrupt context saving
11541 were not getting allocated.
11543 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11546 Fixed left shift. Will promote the left side of a left shift
11547 if a) left shifting more than size of operand or b) when assigned
11548 to something size > size of left side
11550 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11661 Previous fix was not good. basic blocks that have "break" or "return" are
11662 not really partof a loop , but live ranges used in these blocks should
11663 be live thru the entire loop, so set partOfLoop but don't add them to
