Commit Message

David Malcolm Jan. 30, 2015, 11:11 a.m. UTC 
jit_langhook_type_for_mode was failing for DImode on arm
(see via a segfault in test-expressions.c.exe in the jit testsuite).

A fix is to add handling for:
  mode == TYPE_MODE (long_long_integer_type_node)
to the existing checks.

gcc/jit/ChangeLog:
	PR jit/64810
	* dummy-frontend.c (jit_langhook_type_for_mode): Support
	TYPE_MODE (long_long_integer_type_node).
