Bug ID: 25964
Summary: -Wliteral-conversion diagnostic with negative values
could be improved
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: aa...@aaronballman.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Consider the following code:
void f() {
bool b1 = -0.99f;
}
This produces the diagnostic: implicit conversion from 'float' to 'bool'
changes value from 0.99 to true
While it's valid to drop the negative sign in the diagnostic (because that's
not part of the literal value, but is instead an expression), it can still be a
bit confusing to users. It might fit programmer's mental models more closely
for the diagnostic to print -0.99 instead.
