Bug ID: 46409
Summary: Failure to optimize out strcpy call when passed a
parameter that could be evaluated at constant time
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
char *f(void)
{
char *p = (char *)malloc(1);
char s[] = "";
strcpy(p, s);
return p;
}
The call to strcpy can be omitted her and just replaced by `*p = 0;`. This
transformation is done by GCC, but not by LLVM.
