    • Fix computation of single entry/exit of a region. · 402cab17 
      For basic block with two preds, allow (as single entry) only when the other
edge is a backedge. Similarly for basic block with two succs,
allow (as single exit) only when the other edge is a back edge.

    • Give EH_ELSE access to __builtin_eh_pointer · b5c4bc31 
      The must-not-throw wrapper for protect_cleanup_actions gets in
the way of being able to access __builtin_eh_pointer without
confusion as the identit of the exception to which we are
referring (b_eh_p has no usable argument up to this point).

Since EH_ELSE never comes from user derived code, let's drop
the c++ specific wrapping.

	* tree-eh.c (honor_protect_cleanup_actions): Do not wrap
	eh_else in a must-not-throw; set ehp_region for it too.

    • [PATCH] Use call-clobbered register for sibcall via GOT · af9345d7 
      From: H.J. Lu  <hongjiu.lu@intel.com>

Since sibcall never returns, we can only use call-clobbered register as
GOT base.  Otherwise, callee-saved register used as GOT base won't be
properly restored.  sibcall_memory_operand is changed to allow 32-bit
GOT slot only with pseudo register as GOT base for RTL expansion.  2
new patterns, *sibcall_GOT_32 and *sibcall_value_GOT_32, are added to
expose GOT base register to register allocator so that call-clobbered
register will be used for GOT base.
