Well, so the problem is:
static bool
ix86_valid_target_attribute_p (tree fndecl,
tree ARG_UNUSED (name),
tree args,
int ARG_UNUSED (flags))
{
...
new_optimize = build_optimization_node ();
...
if (old_optimize != new_optimize)
DECL_FUNCTION_SPECIFIC_OPTIMIZATION (fndecl) = new_optimize;
for some reason the optimization flags are believed to not match despite the
fact only target attribute is used. The difference is:
- <optimization_node 0x143209100
+ <optimization_node 0x100fda500
align_functions (0x10)
align_jumps (0x10)
align_labels (0x1)
@@ -95,5 +96,6 @@
flag_unwind_tables (0x1)
flag_var_tracking (0x1)
flag_var_tracking_assignments (0x1)
+ flag_var_tracking_uninit (0x1)

so it seems that re-running process_options on darwin somehow leads to this
change. Adding Joseph to CC.
Still streaming of optimization attribute is thing we should do.
