This broke on x86_64 in the last day or so, I thought maybe you might know
what happened. (You touched config/i386 FP stuff recently.) I'm seeing a
regression in gcc.target/i386/pr32268.c as seen here:
http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg01108.html
Right now the execute failures only appear with -fpic/-fPIC, however I
believe this is because inlining is masking the problem and allowing
things to get folded. With -fpic/-fPIC the inlining is disabled and the
abort occurs.
You can trigger the bug in a regular pass by applying the following
noinline patch to the testcase. Thoughts?
How does it break? It works for me with noinline and with -fPIC.
You need to patch the testcase. The change was somehow trivial
(effectively changed return mode of TFmode soft-fp compare from "long"
into __libgcc_cmp_return__ mode, which should be the same). I'll look
into it tomorrow.
Thanks,
