D.gnu - Assembler problem while trying to integrate D iompiler in GCC suite

Hi all,
I'm trying to integrate the D frontend for GCC in the GCC 3.4.4 release,
I'm in contact with the maintainer David Friedman, he successfully
compiled the current (0.12.1) sources with MinGW and I expect that he
also has tested it with other supported platforms, however I get this
error now and I have not really an idea what the reason may be. I found
one patch for gas for another platform:
http://sources.redhat.com/bugzilla/show_bug.cgi?id=857
http://sources.redhat.com/bugzilla/show_bug.cgi?id=936
http://sourceware.org/ml/binutils/2005-05/msg00289.html
However I don't know if this is related or if there may be another
problem with the e.g. source.
What is new in the source regarding this problem is this patch which
gives me the error cited below:

I found one patch for gas for another platform: http://sources.redhat.com/bugzilla/show_bug.cgi?id=857 http://sources.redhat.com/bugzilla/show_bug.cgi?id=936 http://sourceware.org/ml/binutils/2005-05/msg00289.html However I don't know if this is related or if there may be another problem with the e.g. source. What is new in the source regarding this problem is this patch which gives me the error cited below:*************** *** 1787,1799 **** IRState::outputThunk(tree thunk_decl, tree target_decl, int offset) { int delta = -offset; ! tree alias = target_decl; TREE_ADDRESSABLE(target_decl) = 1; TREE_USED(target_decl) = 1; #if D_GCC_VER >= 34 DECL_VISIBILITY (thunk_decl) = DECL_VISIBILITY (target_decl); ! #ifdef ASM_OUTPUT_DEF if (targetm.have_named_sections) { resolve_unique_section (target_decl, 0, flag_function_sections); --- 1844,1866 ---- IRState::outputThunk(tree thunk_decl, tree target_decl, int offset) { int delta = -offset; ! tree alias; ! #if D_GCC_VER >= 34 ! #ifdef ASM_OUTPUT_DEF ! alias = make_alias_for_thunk(target_decl); ! #else ! alias = target_decl; ! #endif ! #else ! alias = target_decl; ! #endif TREE_ADDRESSABLE(target_decl) = 1; TREE_USED(target_decl) = 1; #if D_GCC_VER >= 34 DECL_VISIBILITY (thunk_decl) = DECL_VISIBILITY (target_decl); ! #if defined (ASM_OUTPUT_DEF) \ ! && !defined (TARGET_IS_PE_COFF) if (targetm.have_named_sections) { resolve_unique_section (target_decl, 0, flag_function_sections);Maybe this is the problem here: ! && !defined (TARGET_IS_PE_COFF) Is TARGET_IS_PE_COFF defined for Cygwin?

See you later, GerritThat check for TARGET_IS_PE_COFF is necessary. Without it, there is a very nasty code gen bug that won't show up until you run the code.

Yes, now it compiles, thank you.
