--- Additional Comments From schwab at suse dot de 2005-05-31 10:57 --- Almost the complete set of predicate registers is live throughout most of function writet1, this looks bogus. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21721

--- Additional Comments From sje at cup dot hp dot com 2005-05-31 21:10 --- It looks like this is due to code in ia64/ia64.c (ia64_compute_frame_size). If we need to store any predicate register (before a call I presume), the code stores them all and sets regs_ever_live[regno] to 1 for all predicate registers. There are question marks in the comment for this code. It looks like it was added in version 1.40 of ia64.c by rth. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21721

--- Additional Comments From sje at cup dot hp dot com 2005-05-27 18:23 --- I am not sure the underlying problem is fixed. The assembly language error seems to come from the line: .pred.rel.mutex p0, p1 p0 is a fixed predicate register and should never show up here. p1 is not used in this program and due to the way GCC allocates predicate registers on IA64 I don't think GCC can ever use p1. The routine emit_predicate_relation_info in config/ia64/ia64.c looks at all predicate registers to see if it should put out a pred.rel.mutex for them. I wonder if it should even look at p0. We could have it start at p2 instead. But maybe it would be better to understand why it thinks it needs a mutex for p0 in this case. -- What|Removed |Added CC||sje at cup dot hp dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21721
