The initial change was insufficiently complete for always getting the semantics of __builtin_longjmp correct. The builtin is translated into a `tInt_eh_sjlj_longjmp` DAG node. This node set R7 as clobbered. However, the code would then follow up with a clobber of R11. I had failed to notice the imp-def,kill on R7 in the isel. Unfortunately, it seems that it is not possible to conditionalise the Defs list via an !if. Instead, construct a new parallel WIN node and prefer that when targeting windows. This ensures that we now both correctly model the __builtin_longjmp as well as construct the frame in a more ABI conformant manner. llvm-svn: 263123 |
