http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54642 --- Comment #5 from Jack Howarth howarth at nitro dot med.uc.edu 2012-09-21 13:49:09 UTC --- This failure is caused by the commit... Author: hubicka Date: Wed Sep 19 10:01:56 2012 New Revision: 191466 URL: http://gcc.gnu.org/viewcvs?root=gccview=revrev=191466 Log: * symtab.c (insert_to_assembler_name_hash): Do not insert register vars. (unlink_from_assembler_name_hash): NULL out pointers of unlinked var. (symtab_prevail_in_asm_name_hash): New. (symtab_initialize_asm_name_hash): Break out from ... (symtab_node_for_asm): ... here. (dump_symtab_base): Dump LTO file data. (verify_symtab_base): Register vars are not in symtab. * cgraph.h (symtab_initialize_asm_name_hash, symtab_prevail_in_asm_name_hash): New functions. (symtab_real_symbol_p): New inline. * lto-symtab.c: Do not include gt-lto-symtab.h. (lto_symtab_entry_def): Remove. (lto_symtab_entry_t): Remove. (lto_symtab_identifiers): Remove. (lto_symtab_free): Remove. (lto_symtab_entry_hash): Remove. (lto_symtab_entry_eq): Remove. (lto_symtab_entry_marked_p): Remove. (lto_symtab_maybe_init_hash_table): Remove. (resolution_guessed_p, set_resolution_guessed): New functions. (lto_symtab_register_decl): Only set resolution info. (lto_symtab_get, lto_symtab_get_resolution): Remove. (lto_symtab_merge): Reorg to work across symtab; do nothing if decls are same. (lto_symtab_resolve_replaceable_p): Reorg to work on symtab. (lto_symtab_resolve_can_prevail_p): Likewise; only real symbols can prevail. (lto_symtab_resolve_symbols): Reorg to work on symtab. (lto_symtab_merge_decls_2): Likewise. (lto_symtab_merge_decls_1): Likewise; add debug dumps. (lto_symtab_merge_decls): Likewise; do not merge at ltrans stage. (lto_symtab_merge_cgraph_nodes_1): Reorg to work on symtab. (lto_symtab_merge_cgraph_nodes): Likewise; do not merge at ltrans stage. (lto_symtab_prevailing_decl): Rewrite to lookup into symtab. * lto-streaer.h (lto_symtab_free): Remove. * lto-cgraph.c (add_references): Cleanup. * varpool.c (varpool_assemble_decl): Skip hard regs. * lto.c (lto_materialize_function): Update confused comment. (read_cgraph_and_symbols): Do not free symtab. At r191465, the mkheaders installation step doesn't trigger the recompilation of lto-symtab.o.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54642 --- Comment #6 from Jack Howarth howarth at nitro dot med.uc.edu 2012-09-21 14:00:03 UTC --- The recompilation of lto-symtab.o during 'make install', but not the -Werror related build failure, can be reproduced on x86_64-apple-darwin12 with... % setenv CC clang % setenv CXX clang++ % ../gcc-4.8-20120920/configure --prefix=/Users/howarth/dist --enable-languages=c,c++,lto --with-gmp=/sw --with-libiconv-prefix=/sw --with-isl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib --enable-checking=yes --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --disable-bootstrap % make % make install where lto-symtab.o is recompiled starting with the r191466 commit. I assume that nothing should be recompiled during 'make install' since that appears to use the system compiler set with the CC/CXX environmentals and not the newly built compiler.

And stage2 and later are built by gcc, not by other compilers.
