Did you mean MOVE_RATIO?
In any case. I can't reproduce this test case on x86 with various combinations
of --param sra-max-structure-size and --param sra-field-structure-ratio=100. I
get clean bootstraps with Ada too.
I'll see if my ppc has Ada installed. In the meantime, could you show me the IL
snippets where we fail and what SRA did in that function? The test case is
still rather large.
Thanks. Diego.
