Duncan Sands 1770ae1ae4 Replacing zero-sized alloca's with a null pointer is too aggressive, instead ... merge all zero-sized alloca's into one, fixing c43204g from the Ada ACATS conformance testsuite. What happened there was that a variable sized object was being allocated on the stack, "alloca i8, i32 %size". It was then being passed to another function, which tested that the address was not null (raising an exception if it was) then manipulated %size bytes in it (load and/or store). The optimizers cleverly managed to deduce that %size was zero (congratulations to them, as it isn't at all obvious), which made the alloca zero size, causing the optimizers to replace it with null, which then caused the check mentioned above to fail, and the exception to be raised, wrongly. Note that no loads and stores were actually being done to the alloca (the loop that does them is executed %size times, i.e. is not executed), only the not-null address check. llvm-svn: 159202		2012-06-26 13:39:21 +00:00
