2010-08-24Do not check whether memory references accessed in every iteration trap.Sebastian Pop1-16/+14
This patch relaxes the checks from gimple_could_trap_p in order to allow the flag_loop_if_convert_stores to if-convert more loops in which it is possible to prove that: - the accesses to an array in a loop do not trap (more than the original non-if-converted loop). This is true when the memory accesses are executed at every iteration of the if-converted loop. - the writes to memory occur on arrays that are not const qualified. This is true when there exists at least one unconditional write to the array in the analyzed program. In this patch this analysis is limited to the loop to be if-converted. * gimple.c (gimple_could_trap_p_1): Not static anymore. Pass an extra bool parameter include_mem.
