Martin Sebor commented on STDCXX-547: ------------------------------------- The Windows warnings seem slightly different, especially the void* to long conversion which might actually indicate a bug in our code since long on 64-bit Windows is smaller than a pointer. Could you please open a separate issue for each distinct class of warnings on Windows? > [Sun C++] 64-bit conversion warnings building the library > --------------------------------------------------------- > > Key: STDCXX-547 > URL: https://issues.apache.org/jira/browse/STDCXX-547 > Project: C++ Standard Library > Issue Type: Bug > Components: Build > Affects Versions: trunk > Environment: Sun C++ +w, wide mode (-xarch=amd64, -xarch=sparcv9, or > -m64) > Reporter: Martin Sebor > Assignee: Martin Sebor > Priority: Minor > Fix For: 4.2 > > > We get a bunch of 64-bit conversion warnings when building the library in > wide (64-bit) mode with Sun C++ 5.8 and 5.9: > gmake: Entering directory `$(BUILDDIR)/lib' > CC -c -D_RWSTDDEBUG -mt -I$(TOPDIR)/include -I$(BUILDDIR)/include > -library=%none -g -xarch=amd64 +w -errtags -erroff=hidef > $(TOPDIR)/src/assert.cpp > ... > CC -c -D_RWSTDDEBUG -mt -I$(TOPDIR)/include -I$(BUILDDIR)/include > -library=%none -g -xarch=amd64 +w -errtags -erroff=hidef > $(TOPDIR)/src/locale_core.cpp > "$(TOPDIR)/src/locale_core.cpp", line 141: Warning, truncwarn: Conversion of > 64 bit type value to "int" causes truncation. > "$(TOPDIR)/src/locale_core.cpp", line 141: Warning, truncwarn: Conversion of > 64 bit type value to "int" causes truncation. > 2 Warning(s) detected. > ... > CC -c -D_RWSTDDEBUG -mt -I$(TOPDIR)/include -I$(BUILDDIR)/include > -library=%none -g -xarch=amd64 +w -errtags -erroff=hidef > $(TOPDIR)/src/num_get.cpp > "$(TOPDIR)/src/num_get.cpp", line 432: Warning, truncwarn: Conversion of 64 > bit type value to "unsigned" causes truncation. > "$(TOPDIR)/src/num_get.cpp", line 461: Warning, truncwarn: Conversion of 64 > bit type value to "int" causes truncation. > 2 Warning(s) detected. > CC -c -D_RWSTDDEBUG -mt -I$(TOPDIR)/include -I$(BUILDDIR)/include > -library=%none -g -xarch=amd64 +w -errtags -erroff=hidef > $(TOPDIR)/src/num_put.cpp > "$(TOPDIR)/src/num_put.cpp", line 417: Warning, truncwarn: Conversion of 64 > bit type value to "const int" causes truncation. > "$(TOPDIR)/src/num_put.cpp", line 417: Warning, truncwarn: Conversion of 64 > bit type value to "const int" causes truncation. > "$(TOPDIR)/src/num_put.cpp", line 745: Warning, truncwarn: Conversion of 64 > bit type value to "int" causes truncation. > "$(TOPDIR)/src/num_put.cpp", line 772: Warning, truncwarn: Conversion of 64 > bit type value to "int" causes truncation. > "$(TOPDIR)/src/num_put.cpp", line 802: Warning, truncwarn: Conversion of 64 > bit type value to "int" causes truncation. > "$(TOPDIR)/src/num_put.cpp", line 830: Warning, truncwarn: Conversion of 64 > bit type value to "int" causes truncation. > 6 Warning(s) detected. > ... > CC -xar -o libstd.a assert.o atomic-cxx.o bitset.o catalog.o codecvt.o > collate.o ctype.o ctype_bits.o domain_error.o exception.o export.o facet.o > file.o instance.o ios.o ios_bits.o iostore.o iostream.o iso2022.o limits.o > limits_bits.o locale_bits.o locale_body.o locale_classic.o locale_combine.o > locale_core.o locale_eq.o locale_global.o locale_name.o logic_error.o > memattr.o memory.o messages.o mman.o num_get.o num_put.o once.o punct.o > random.o range_error.o runtime_error.o setlocale.o string.o strstream.o > strtol.o ti_collate.o ti_filebuf.o ti_insert_dbl.o ti_insert_int.o > ti_insert_ptr.o ti_ios.o ti_istream.o ti_messages.o ti_money_get.o > ti_money_put.o ti_moneypunct.o ti_num_get.o ti_num_put.o ti_numpunct.o > ti_ostream.o ti_podarray.o ti_streambuf.o ti_string.o ti_stringbuf.o > ti_time_get.o ti_time_put.o ti_wcollate.o ti_wfilebuf.o ti_winsert_dbl.o > ti_winsert_int.o ti_winsert_ptr.o ti_wios.o ti_wistream.o ti_wmessages.o > ti_wmoney_get.o ti_wmoney_put.o ti_wmoneypunct.o ti_wnum_get.o ti_wnum_put.o > ti_wnumpunct.o ti_wostream.o ti_wstreambuf.o ti_wstring.o ti_wstringbuf.o > ti_wtime_get.o ti_wtime_put.o time_get.o time_put.o tmpbuf.o typeinfo.o > valarray.o vecbool.o version.o wcodecvt.o wctype.o > gencat rwstderr.cat $(TOPDIR)/src/rwstderr.msg > gmake: Leaving directory `$(BUILDDIR)/lib' -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
