Hello,
The attached deprecates SIGTRAMP_START and SIGTRAMP_END. These were made obsolete by PC_IN_SIGTRAMP (which in turn has been made obsolete by signal trampoline frame sniffers).
Note that blockframe.c:find_pc_partial_function contains what I consider to be broken references to these macros -- typically it is only possible to determine the location of a signal trampoline by doing a detailed analysis of the inferior (i.e., unwinding frames and examining instructions) yet that function is ment to work with just static information. I've added a comment explaining this.
comments?
I'll look to commit this in a week.
