1447 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1448 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1450 One basic decision: e.g. src/clean.mk includes further files. In order
1451 to make this work there are two solutions:
1452 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1453 run configure on them. This way they can use
1454 'include $(srcdir)/port-clean.mk'
1455 - always include clean.mk by the Makefile at the same level. To avoid
1456 that `make clean` tries to include and build Makefile.dep the
1457 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1458 implemented, because now even `make uninstall` doesn't create
1459 Makefile.in. clean.mk could be eliminated by pasting it in
1462 * debugger/mcs51/Makefile.in: build own objects from library sources
1463 (SLIB, SDCC) in current directory
1465 * configure, configure.in: renamed --disable-device-lib-build in
1466 --disable-device-lib; added --enable-doc, the required tools are
1467 searched by configure; added result message; the toolchain for the
1468 belonging ports are now only built, if the port is enabled.
1470 * support/regression/*: all output is written in directory gen, because
1471 the fwk and ports directories don't livet in the build tree using vpath
1473 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1474 --disable-device-lib, added --enable-doc, added section VPATH
1476 * sim/ucsim/configure.in,
1477 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1478 z80 are enabled by default
1480 2006-04-24 Raphael Neider <rneider AT web.de>
1482 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1483 to config word, "pic14_"-prefixed some extern functions
1484 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1485 config word has been found
1486 * src/pic/device.h: added prototypes
1487 * src/pic/pcode.c: added "pic14_"-prefix where needed

1490 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1851 2006-03-06 Borut Razem <borut.razem AT siol.net>
1853 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1854 made the linker quiet
1856 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1859 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1860 which dumps before the function entry point a data byte which represents
1861 the number of the local variables used by the specified function, added
1862 'xinst' for initial support for Extended Instruction Support,
1863 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1864 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1865 port->fun_prefix anymore (may change later),
1866 (genFunction, genEndFunction): do not store/restore local registers for
1867 _main (this should take care the --main-return command line option in
1869 (genOr): removed some legacy pic-port instructions,
1870 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1871 performing operations with SFR's causes data to be written more than

1881 (commented out for reference), didn't account for some registers which
1882 were left marked 'not free' after a pointer operation. The change
1883 reduces register usage a lot in some cases

4241 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4243 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4245 * device/lib/printf_large.c: removed inline assembly for portability and
4246 readability. Use printf_fast if speed or size are more important.
4247 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4248 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4250 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4252 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4253 prevent compiler warning
4255 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4257 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4258 moved to level 0 and declared as static. Also they are explicit
4259 placed in access bank. This was necessery because some times they
4260 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4261 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4262 optimizations. Currently only compare to unsigned char is implemented,
4263 * src/pic16/gen.c: added fReturnIdx array,
4264 * (struct resolvedIfx) is moved to gen.h and made public,
4265 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4266 * (aopForSym): added an optimization to directly store in stack of
4267 the operand of a SEND iCode,
4268 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4269 but as registers instead (AOP_REG) using the fReturnIdx array,
4270 * (pic16_freeAsmop): remove the freed register from the
4271 _G.sregsAlloc field,
4272 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4273 a compare of 'WREG',
4274 * (pic16_popGetTempRegCond): changed function prototype, now
4275 function takes also a bitVector argument v which holds the current
4276 set of registers that are allocated for stack access by aopForSym,
4277 registers allocated in aopForSym for accessing stack symbols are not
4278 any more part of the functions usedRegs field,
4279 * (genCall): some times aopOp is called for a stack variable to be
4280 send, aopForSym might perform the push, if this is true make sure
4281 that genCall doesn't push the variable twice by testing _G.resDirect,
4282 * (genFunction): changed testing for unspecified interrupt number
4283 from 256 to INTNO_UNSPEC,
4284 * modified selection scheme of frame pointer generation. Previously
4285 if function did use local registers a frame pointer was generated,
4286 now a frame pointer is generated only if function has arguments
4287 (that need PLUSW2 register access), or has stack arguments, or the
4288 compiler is not instructed to omit the frame pointer,
4289 * (genEndFunction): before restoring local registers that were saved
4290 in the function preamble, also restore the registers that *might*
4291 have been allocated for stack access,
4292 * (genRet): removed some old comments,
4293 * (genCmp, the active (RN's) version): added a call to the
4294 pic16_genCmp_special function to perform the compare with a more
4295 robust and optimized way,
4296 * (genInline): a feature has been added in inline code generation,
4297 which allows a wildcard variable substitution when writing inline
4298 assembly. Code is incomplete and experimental therefore undocumented,
4299 * (genCast): changed order of aopOp for result and right to allow
4300 aopForSym to directly load the result if possible,
4301 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4302 perform an optimized compare on some selected special occasions,
4303 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4304 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4305 generate an IVT any more,
4306 * src/pic16/main.c (pic16_optionsTable): added command line option
4308 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4309 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4311 * src/pic16/NOTES: Raphael Neider added in list of active developers
4312 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and

5007 * added libc directory. The current version of LibC contains string
5008 functions, ctype functions and macros and some functions of the
5009 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5010 be extensively tested in the future. Standard disclaimer here.
5011 Library is not automatically build yet. But one can build it by

5023 * (pic16_storeForReturn): optimized return of 0,
5024 * (genCmp): experimental code for new genCmp which uses PIC18's
5025 special compare&skip instructions. Initial tests fail some times
5026 with variables grater than 1 byte in size, so new code is disabled,
5027 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5029 * (genCast): began a fix to optimize the casting of a bit to another
5030 bit, now assigning a bitfield to another bitfield will fail, sorry,

8056 loaded with the linker search paths (-L arguments) and the libraries
8057 to be linked with the current source (-l arguments). Changes
8058 currently will affect only the pic16 port.
8059 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8060 include path the port specific paths and port specific libraries,
8061 * gplink command now contains the $3 argument,
8062 * src/pic16/device.h,

8079 Documenting changes from previous commits.
8080 * configure.in (version 1.56),
8081 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8082 when generating output files to configure the pic16 library,
8083 but now I've commented it out, since gputils aren't installed in the
8084 SF compile farm, so library won't compile
8086 * device/lib/Makefile.in (version 1.56): initially I've added in
8087 target 'all' the prerequestive 'model-pic16' so it compiled the
8088 pic16 library, but now I've commented it out for the same reasons
8090 * added targets 'model-pic16' and 'objects-pic16' to compile the
8092 * added target 'port-specific-objects-pic16' to handle the
8093 generated libraries and copy them into the build/ directory
8094 * added target 'clean-intermediate-pic16' to clean intermediate
8095 files into pic16 directory
8096 * in target 'installdirs' added line to create directory pic16 in

8100 added lines to copy all header files to installation path,
8101 * in target 'installdirs' added line create directory for pic16
8102 headers in the installation path

8342 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8343 LEFT_OP (left shift)
8345 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8347 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8348 (default behaviour).
8350 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8352 A python script to validate compiler diagnostic messages. It can be
8353 used to verify that sdcc complains about bad c source code and
8354 gives a good location of the error.
8355 * support/valdiag/Makefile,
8356 * support/valdiag/valdiag.py,
8357 * support/valdiag/tests/*

8370 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8372 * src/common.h: added ifndef/define/endif macros
8373 around the header file.
8374 Bug reported from Jesus Calvino-Fraga
8376 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8378 * sdcc.spec: updated
8379 * device/include/Makefile.in: don't install CVS directories
8380 * device/lib/Makefile.in: added removal of CVS directories after install
8381 * doc/Makefile: fixed install, added local_icons
8382 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8383 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8384 * src/ds390/gen.c (genRightShift): fixed bug #870788
8385 * src/SDCCast.c (decorateType): fixed bug #870781
8387 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8389 PIC16 port related changes:
8390 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8391 added variable stackPos,
8393 * gen.c: genCall, assignResultValue: added support for
8394 pushing/retrieving function parameters to/from stack,
8395 genFunction,genEndFunction: setup stack frame for the
8397 genAddrOf: will be changed according to bug 863624
8399 * added files genutils.c and genutils.h which contain gen*
8400 debugged and optimised functions extracted from gen.c
8402 * glue.c: added variable 'externs' which holds extern symbols,
8403 pic16emitRegularMap: is modified to properly handle relocatable
8404 symbols under the new scheme,
8405 pic16createInterruptVect: is modified
8406 pic16printPublics: is modified to emit 'global' assembler directives,
8407 added pic16_printExterns to print extern symbols,
8408 pic16glue: initializes stack/frame pointer in the beginning of
8409 the assembly output. Temporary hack, will be corrected later,
8410 because gplink yet does not support stack and SDCC does not
8411 yet support a type of crt0.o object to create the final binary.
8413 * Removed many lines that contain 8051 legacy code.
8414 * The code is finally placed under a 'code' directive.
8415 * Added port specific options.
8417 * _process_pragma: simplified since now we do not need *special*
8418 include file to define SFR registers. But a separate header
8419 will be needed. This will be developed later.
8420 * _pic16_parseOptions: added, parses port specific options:
8421 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8422 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8423 --preplace-udata-with=
8425 * _pic16_setDefaultOptions: modified to initialize section names,
8426 but hack is temporarly out of order since it needs improvement.
8427 * _pic16_genAssemblerPreamble: configuration words are emitted by
8428 their address instead of their name. This part is incomplete and
8429 supports only the 18Fxx2 devices. Other devices will emit an error
8430 during assembly since they do not contain the same set of config
8432 * _pic16_genIVT: is modified,
8434 * pcode.c: added definitions for some hardware registers that are needed
8436 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8437 All PCI entries are updated. Now LFSR is supported.
8438 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8439 * added pic16_newpCodeOpLit2 to support instructions with
8440 two literal arguments
8441 * pic16_pCode2str: corrected code that emits assembler instructions
8442 with two literal operands and those that have an access bit modifier
8443 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8444 this fixes a bug which caused some labels to be lost, when an
8445 assembler directive was added, i.e. banksel,
8446 * pic16_FixRegisterBanking: improved logic that causes the insertion
8448 * InlineFunction: functions that are called once, are not any more
8449 inlined. This can be a port option in the future,
8451 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8453 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8454 hold the corresponding uninitialized symbols,
8455 * pic16_allocProcessorRegister: registers have explicit marked the
8457 * pic16_allocInternalRegister: registers are explicit marked as
8459 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8460 processing list, so bit registers were lost,
8463 * ralloc.h: added field 'accessBank' and original symbol operand
8464 in register definition,
8465 * removed the field isMapped from register definition,
8467 ** Several functions have been removed from various sources:
8468 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8469 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8470 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8471 pic16_assignRelocatableRegisters
8473 ** others have been introduced:
8474 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8475 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8477 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8479 * support/scripts/inc2h.pl: changed definition of BIT_AT
8480 to emit 'sbit at' instead of 'bit at'. This was a request.
8482 PIC16 port related preliminary changes:
8483 * gen.c: prefixed function popRegFromString with
8484 pic16_ and all references to it corrected
8485 * pcode.c: all pic16_pc_* hardware registers prefixed
8486 with underscore (_),
8487 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8488 * ralloc.c: newReg(): when register is REG_SFR then
8489 set address to rIdx,
8490 pic16_allocProcessorRegister(): marks register wasUsed=0
8491 pic16_writeUsedRegs(): added a call to assign processor
8492 registers via pic16_assignFixedRegisters
8494 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8496 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8497 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8498 variables in unused register banks. Also the SSEG is placed
8499 wherever there is enough space for it, and IDATA can be anywhere
8500 in internal RAM. For now compile using -Wl-Y[stack_size].
8501 The mem file is different for this option as well, since it
8502 makes no sense of talking about DSEG lenght.
8504 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8506 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8507 in certain cases, e.g. when ROM assignment, patch provided
8508 from Albert den Haan.
8510 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8653 * src/mcs51/peephole.def,
8654 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8749 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8751 * src/SDCCast.c (decorateType): disabled a transformation I added in
8752 revision 1.188 (access to fields of a structure at an absolute address);
8753 it breaks with bitfields, extern declarations, and gcse analysis.
8754 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8755 could be assigned through a pointer, so don't complain.
8756 * src/SDCCast.c (astErrors),
8758 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9395 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9396 support for standard C idiom of memory mapped variables; for
9397 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9398 to xdata int at 0x1234 tempvar = 1.
9399 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9400 provided by Akiya ISHIDA

9416 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9418 Fixed bug #621531 (const & volatile confusion in the type chain).
9419 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9511 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9512 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9513 fetching of the pointer
9514 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9515 copied from genNearPointerSet()
9516 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9517 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9518 If they pop r0/r1 they must be called in the opposite order than aopOp().
9519 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9520 (resp. --stack-auto), prepared for --xstack

9531 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9533 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9534 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9535 type for bits was changed. It resulted in bit variables becoming
9536 global, which is not permitted in PIC 14 assembly output.
9538 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9540 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9553 A few small changes that speed up the peephole optimizer.
9557 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9559 Try to make the peephole optimizer smarter by maintaining
9560 an association between the assembly source code and the
9561 iCodes that originated them. Put this information to use
9562 with a new peephole rule condition "notVolatile" so that
9563 the rules can be aggressive yet still safe.
9568 * src/mcs51/peeph.def
9570 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9574 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9575 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9576 if the left or right operand symbols have the accuse flag set.
9578 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9580 Changed the type of the result of the ! (NOT) operator to char;
9581 previously it returned the same type as the source. This allows
9582 us to eliminate all the genFloatNot functions (all of its target
9583 implementations were very buggy) since !float can use the same
9586 * src/SDCCicode.c (ast2iCode): ! returns char

9595 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9596 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9597 during interrupts. Ensure WSAVE is located at a shared bank address.
9598 2. Fixed page selection in some places
9599 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9600 the registers name strings.
9601 4. Fixed "signed / unsigned compare" compiler warnings.
9602 5. The PIC port manages its own allocation of the general purpose
9603 registers, but makes no attempt to reuse them. As a result when
9604 compiling it soon runs out of general purpose registers. Some
9605 additional code was added to the files pcode.c and device.c to walk
9606 through the function call tree and rename the registers so that they
9616 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9617 genPlus() & genMinus() when the result is the same as left or right
9619 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9623 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9625 Made bitfield a distinct type from bit so that bitfields
9626 convert as per ANSI C and bits retain their traditional
9627 boolean style behaviour. Implemented bitfield support in
9635 * src/ds390/gen.c: bit v bitfield split
9636 * src/z80/gen.c: New support for bitfields
9637 * support/regression/tests/bitfields.c: reenabled z80,
9640 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9642 Rules 246.x, 247.x relate to bitfields, the others speed up
9643 access to xdata mapped I/O devices.
9645 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9647 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9649 Cleaned up genPackBits and genUnpackBits and added two helper
9650 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9651 for literal assignments in genPackBits (thanks to Frieder for
9657 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9659 Fixed bug #748310 (pointer to function type mishandled when the
9660 function name is omitted). Also fixed a SIGSEGV when a function
9661 attribute (reentrant, etc) is used on a non-function or on a
9662 function but misplaced before the parameter list.
9664 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9666 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9667 * support/Util/SDCCerr.h,
9668 * support/Util/SDCCerr.c: Added func attr misuse error msg

9689 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9691 Made the constant following the "interrupt" keyword optional. If
9692 omitted, the function will not automatically be given an entry
9693 in the interrupt vector table (similar to #pragma NOIV, but
9694 less syntacticly kludgy). The interrupt number is also now
9695 range checked. Also fixed a bug in the high order bit example

9709 * src/SDCCicode.c (operandOperation): rewritten some ops
9710 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9711 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9713 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9714 be re-activated by defining REDUCE_LITERALS)
9715 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9716 unsigned, but are signed by default
9717 * src/SDCCval.c (constVal): rearranged
9718 * src/SDCCval.c (valMod): preliminary fix
9719 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9761 constants are unsigned; added recognition of "u" flag for unsigned
9762 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9763 * src/SDCCval.c (valDiv, valMod): fixed signdness
9764 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9765 signedness of modulo, left and right shift

9820 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
9822 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
9823 there, while the mantissa of a double is "only" 53 bits wide.
9825 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

10227 support for the PIc16 port in the ports table, when executing
10228 the compiler with no port specified on command line, a default
10229 port is selected with the new macro DEFAULT_PORT which is
10230 defined in port.h, in setDefaultOptions() linkOptions is removed
10231 from initialization assignment, since now it is a set,
10232 parseCmdLine uses setParseWithComma for linkOptions, in
10233 linkEdit() linkOptions are accessed with new function indexSet()
10234 which returns the i'th item of a set variable. See SDCCset.c, in
10235 linkEdit() when calling buildCmdLine(), added linkOptions as

10251 gpasm complaining and test the linkage with gplink, _linkCmd and
10252 _asmCmd changed to be more gplink and gpasm friendly
10253 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10254 produced an error when parsed, peep rule 12 is added to utilize
10255 movff, but it is commented out since the pCode does not support
10256 yet a command with 2 address arguments

11315 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11316 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11318 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11319 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11321 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11323 * in /sdcc/as/mcs51/ changed these files in order to create an
11324 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11325 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11326 following files to include the previous two files: aslink.dsp,
11327 Makefile.aslink, Makefile.bcc, and Makefile.in.
11329 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11330 .adb instead of .cdb
11332 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11334 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11335 value from option --iram-size.
11337 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11339 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11342 2002-09-18 <wiml AT hhhh.org>
11344 * SDCClrange.h: exposed setFromRange() and setToRange()
11345 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11346 packRegsForAccUse() (bug 542397)
11347 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11348 multiple times and emitting the fetch operations more than once
11349 added aopGetUsesAcc() function to allow binary operators to
11350 fetch their operands in the correct order; made genMinus() emit
11351 compact code for X = LITERAL - Y
11353 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11354 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11355 sprintf() in line 1267.
11357 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11358 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11361 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11362 Changes to aslink (All the changes are marked with 'JCF'):
11364 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11367 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11368 area BSEG. Also moves, if possible, the DATA area down into the internal
11369 ram so more space is available.
11371 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11374 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11375 not bytes. Function summary() which creates a memory usage summary
11376 file with extension .mem. Reports of overlaping stack and small stack
11377 size. If the space for the stack is less than 16 bytes aslink trows a
11380 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11381 the 8051. Option 'y' for memory summary output file.
11383 Changes to sdcc (All the changes are marked with 'JCF'):
11385 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11387 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11388 overlaying area for it (uses RegBankUsed[4]).
11390 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11391 bank zero as used by default. By default aslink locates the stack
11392 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11393 the creation of the .mem file. Delegates the allocation of data area
11394 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11395 the begining of the stack area to aslink.
11397 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11398 glue() in SDCCglue.c creates an area for it.
11400 2002-09-03 Borut Razem <borut.razem AT siol.net>
11401 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11402 sdcc/src/pic/glue.c:
11403 introduced atexit() handler for teporay files removal in case of
11404 errors, assertions, ...
11406 2002-08-29 Borut Razem <borut.razem AT siol.net>
11407 * sdcc/support/cpp2/auto-host_vc_in.h:
11408 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11409 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11410 Maybe there is a similar problem with BORLANDC? It should be checked!
11412 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11413 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11414 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11415 was not executed, and the compiler (cl) launched a warning:
11416 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11418 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11419 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11421 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11422 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11424 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11425 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11426 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11427 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11428 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11429 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11430 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11431 - added Release configuration in VS projects
11432 - review of compiler an linker options
11433 - VC .exe files are generated in bin_vc directory, not to interfere
11434 with binaries generated from other projects (cygwin, mingw, bcc ...)
11436 * sdcc/src/yacc.dsp: added
11438 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11439 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11440 and insert the version number definitions from .version
11442 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11444 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11445 added - genarate auto-host.h using auto-host_vc_in.h as template
11448 removed from CVS, generated automatically
11450 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11451 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11453 2002-08-11 Borut Razem <borut.razem AT siol.net>
11454 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11456 2002-08-10 Borut Razem <borut.razem AT siol.net>
11457 * src/SDCCmain.c (main):
11458 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11459 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11460 The consequence was that some temporary files were not removed.
11463 unification of code in functions tempfilename() and tempfile():
11464 function tempnam() is defined in Visual Studio 6.0 and .NET
11466 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11468 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11469 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11470 - removed compiler command line option /WX: Treats all warnings as errors
11471 - update a list of source files, included into the project
11473 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11474 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11475 changed project type to Generic Project so that can be correcly converted to VS.NET project
11477 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11479 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11481 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11483 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11484 added return 0 statements after assert() to make compiler happy
11486 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11487 added newline in the def file to keep MSC compiler satisfied
11489 * sdcc/src/z80/gen.c:
11490 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11491 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11492 - solved MSC error in function aopDump()
11494 * sdcc_vc.h: define PREFIX as "\\sdcc"
11496 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11497 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11500 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11501 - Rewrote the register banking algorithm.
11502 - Added pCode live-range analysis to registers (for now, only non-used and
11503 singly-used registers optimized away)
11505 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11507 * 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.

11536 2002-03-28 Johan Knol <johan AT balder>
11538 * src/SDCCval.c: fixed bug #532436
11540 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11542 Added "char *Processor" field to the port structure.
11545 Added -p option. Allows port dependent processor to be specified.
11548 Initialized the new field char *Processor field to NULL in all ports
11551 Compiler generated registers for interrupt context saving
11552 were not getting allocated.
11554 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11557 Fixed left shift. Will promote the left side of a left shift
11558 if a) left shifting more than size of operand or b) when assigned
11559 to something size > size of left side
11561 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11563 tons of changes. Register allocation has been
11564 rewritten. Added customization for the various PICs. Flow
11565 analysis is restructured. ...
11567 * src/pic/device.h:
11570 * src/pic/device.c:
11571 Added. device.c is a PIC port hack to accomodate variations

11576 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11578 2002-03-04 johanknol <johanknol AT manik>
11580 * /src/SDCCval.c: fixed
11582 const unsigned char arr[][2] = { { 0, 1 } };

11671 * sdcc/src/SDCCloop.c:
11672 Previous fix was not good. basic blocks that have "break" or "return" are
11673 not really partof a loop , but live ranges used in these blocks should
11674 be live thru the entire loop, so set partOfLoop but don't add them to
