miscompiles POOMA testcase
After a complete test with the patch, regression test results for POOMA
are (compared to Feb01):
+PASSED ... array_test1
+PASSED ... array_test7
+PASSED ... array_test21
+FAILED ... array_test27
+PASSED ... array_test28
+PASSED ... ump_test5: guard cell fill test.
+PASSED ... ump_test7
-PASSED ... gmp_test4 (Guard cell fill test)
-PASSED ... brickviewbase_test2
-FAILED ... brickviewbase_test3
+PASSED ... brickviewbase_test3
-PASSED ... FieldReductions
+PASSED ... Gradient
-PASSED ... OffsetReduction
+PASSED ... FileSetWriter
+PASSED ... FileSetWriterTest2
-PASSED ... TestTranspose
where FAILED ... array_test27 is a known FP precision problem with
gcc-3.3. New PASSED/FAILED without corresponding vanishing FAILED/PASSED
are previous/new compile errors or runtime segfaults.
Should I file a new PR with the loop optimizer ICE?
Thanks,
Richard.
