When I compile a testcase that includes float and inline, it asserts internal compiler error if it is optimized with -O2. If it is optimized with -O, this error is not asserted.
% gcc -c test.c -O2 -m4 test.c: In function 'fff': test.c:19: internal compiler error: in reg_overlap_mentioned_p, at rtlanal.c:1382 Please submit a full bug report, with preprocessed source if appropriate.
