Hi Hal, To get my understanding right, is this a test-case problem or there is a problem with x86 code generation?. I can spend some time to look into the problem.

...of loop vectorizer?. If so, can you please send it across?. I want to see if there are dependencies such as unrolling for the vectorization. In the design we may also have to consider BB vectorizer and loop vectorizer working well together with no ambiguous requirements/dependencies.

PS: Here's how I can reproduce with clang on linux: clang -S -o tsc.ll -O0 -flto -std=gnu99 tsc.c ; clang -S -o dummy.ll -O0 -flto -std=gnu99 dummy.c ; opt -std-compile-opts tsc.ll -S -o tsc.1.ll ; opt -std-compile-opts dummy.ll -S -o dummy.1.ll ; llvm-link tsc.1.ll dummy.1.ll -S -o total.ll ; opt -std-link-opts total.ll -S -o total.1.ll ; llc total.1.ll ; gcc -o z total.1.s The program

Okay, can you resummarize? Do
