Chandler Carruth 6f0ec20e8f Revert "indvars: Improve LFTR by eliminating truncation when comparing ... against a constant." This reverts commit r186107. It didn't handle wrapping arithmetic in the loop correctly and thus caused the following C program to count from 0 to UINT64_MAX instead of from 0 to 255 as intended: #include <stdio.h> int main() { unsigned char first = 0, last = 255; do { printf("%d\n", first); } while (first++ != last); } Full test case and instructions to reproduce with just the -indvars pass sent to the original review thread rather than to r186107's commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186152 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-12 11:18:55 +00:00
