I believe this should be handled like GMPINC: gcc/configure.ac gains an --with-dejagnu option which ultimately sets DEJAGNUINC, that's emitted to site.exp in gcc/Makefile.in so gcc/testsuite/jit.dg/jit.exp can use it. > * When gcc is configured with Solaris as and ld, a couple of tests FAIL like > this: > > NOTE: test-compile-to-assembler.c.exe iteration 2 of 5: writing > reproducer to ./test-compile-to-assembler.c.exe.reproducer.c > ./test-compile-to-assembler.c.exe: error: in get, at cgraph.h:404 > 0xfcfd4d3a symtab_node::get(tree_node const*) > /vol/gcc/src/hg/trunk/local/gcc/cgraph.h:401 > 0xfcfd4d3a decl_comdat_group(tree_node const*) > /vol/gcc/src/hg/trunk/local/gcc/tree.c:708 > 0xfd0ce378 solaris_define_comdat_signature(comdat_entry**, void*) > /vol/gcc/src/hg/trunk/local/gcc/config/sol2.c:267 > 0xfd0ce6d6 void hash_table<comdat_entry_hasher, > xcallocator>::traverse_noresize<void*, > &(solaris_define_comdat_signature(comdat_entry**, void*))>(void*) > /vol/gcc/src/hg/trunk/local/gcc/hash-table.h:969 > 0xfd0ce6d6 void hash_table<comdat_entry_hasher, xcallocator>::traverse<void*, > &(solaris_define_comdat_signature(comdat_entry**, void*))>(void*) > /vol/gcc/src/hg/trunk/local/gcc/hash-table.h:990 > 0xfd0ce6d6 solaris_file_end() > /vol/gcc/src/hg/trunk/local/gcc/config/sol2.c:291 > [...] > FAIL: test-compile-to-assembler.c.exe: non-zero exit code: 7862 exp9 0 4 [...] > Haven't yet started debugging how error_mark arrives there. That those errors only happen during the second iteration seems to point at a GC issue. In fact, there are problems here, cf. PR other/84379), but no solution so far.
