I manually generated all the missing support files and re-ran the testsuite.
I'm now getting 7 failures out of 137 (log attached).
1. incremental_test: suspect this is not really an error (failed v2.21 too)
2. ver_matching_test.sh: __bss_start not local, rtld issue? real issue? (failed on v2.21 too)
3. exception_static_test: likely real problem. gdb log attached
4. intpri2: likely real problem. gdb log attached
5. relro_test: no relro support in rtld, ignore
6. relro_now_test: no relro support in rtld, ignore
7. relro_strip_test: no relro support in rtld, ignore
I'm most worried about tests 3 and 4.
The exception didn't get caught back in exception_test_1.cc. System compiler is gcc 4.4.7
(2011-10-25 snapshot) using dl_iterate_phdr for exception handling.
Test 4 may have failed due to the changed ctors setting in option.h ??
Any comment/guidance about the testsuite results is appreciated.
It looks like gold is fairly healthy on DragonFly after altering option.h though.
