For this C++ code:
extern void g( int);
void f( int a, int b, int c)
{
if (a <= b <= c)
{
g( a);
}
}
given to a couple of recent builds of clang, does this:
Alphasrc $ /home/dcb40b/llvm/results.20250221/bin/clang++ -c -g -O2 -Wall mar2b.cc
mar2b.cc:6:13: warning: comparisons like 'X<=Y<=Z' don't have their mathematical meaning [-Wparentheses]
6 | if (a <= b <= c)
| ^
1 warning generated.
Alphasrc $ /home/dcb40b/llvm/results.20250223/bin/clang++ -c -g -O2 -Wall mar2b.cc
mar2b.cc:6:13: error: comparisons like 'X<=Y<=Z' don't have their mathematical meaning [-Wparentheses]
6 | if (a <= b <= c)
| ^
1 error generated.
Alphasrc $
I think it is an error to error on this code and a warning is fine.
