instcombine: Migrate sprintf optimizations This patch migrates the sprintf optimizations from the simplify-libcalls pass into the instcombine library call simplifier. llvm-svn: 168677
2012-11-27 06:57:54 +01:00
; Test that the sprintf library call simplifier works correctly.
;
; RUN: opt < %s -instcombine -S | FileCheck %s
Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though. Patch by Ron Ofir. llvm-svn: 188173
