Chris Lattner e41d3c015c Teach loop-idiom to turn a loop containing a memset into a larger memset ... when safe. The testcase is basically this nested loop: void foo(char *X) { for (int i = 0; i != 100; ++i) for (int j = 0; j != 100; ++j) X[j+i*100] = 0; } which gets turned into a single memset now. clang -O3 doesn't optimize this yet though due to a phase ordering issue I haven't analyzed yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122806 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-04 07:46:33 +00:00
