------- Comment #5 from siarhei dot siamashka at gmail dot com 2010-03-21 03:33 ------- I don't quite understand what's the problem: "This patch has the unhappy side effect of clobbering s0, s1 and s2 if s3 is used because that's the only way we can indicate that q0 is clobbered by the write to s0."
The proper solution seems to be extremely simple to me and it should do exactly the same what an application programmer would do to workaround the bug. Just when initially parsing clobber list do a simple text substitution "q0" -> "d0", "d1". Same for all the other "q" registers. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43440
