Running the libstdc++ testsuite on NetBSD/sparc or NetBSD/sparc64 results in most tests failing like:
<command line>:1: fatal error: had to relocate PCH compilation terminated. compiler exited with status 1
This is due to a misassumption in ggc-common.c:654 (mmap_gt_pch_use_address):
This version assumes that the kernel honors the START operand of mmap even without MAP_FIXED if START through START+SIZE are not currently mapped with something.
That is not true for NetBSD. Due to MMU idiosyncracies, some architecures (like sparc and sparc64) will align mmap requests that don't have MAP_FIXED set for architecture specific reasons).
Is there a reason why MAP_FIXED isn't used even though it probably should be?
