Bug ID: 31528
Summary: llvm/lib/Support/NativeFormatting.cpp:244: local
variable 'Len' set but not used ?
Product: new-bugs
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: dcb...@hotmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
llvm/lib/Support/NativeFormatting.cpp:244]: (style) Variable 'Len' is modified
but its new value is never used.
Source code is
unsigned Len;
Len = format(Spec.c_str(), N).snprint(Buf, sizeof(Buf));
if (Style == FloatStyle::Percent)
++Len;
S << Buf;
if (Style == FloatStyle::Percent)
S << '%';
}
I am not sure if local variable 'Len' needs to be used in some
way, or can be safely deleted.
