Bug ID: 47065
Summary: Failure to optimize out strcmp based on size of string
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: gabrav...@gmail.com
CC: llvm-bugs@lists.llvm.org
extern char a[4];
bool f()
{
return strcmp(a, "string") == 0;
}
This can be optimized to `return false`. This transformation is done by GCC,
but not by LLVM.
