Subject: [PATCH] Silence sys/sdt.h comparison of unsigned expression < 0 is always false.
|
||
|
|
|
||
|
|
Some arm g++ setups would complain about the wchar_t "signedness detection":
|
||
|
|
sys/sdt.h:102: error: comparison of unsigned expression < 0 is always false
|
||
|
|
|
||
|
|
jistone said: "((T)(-1) < 1)" would still get the right boolean value,
|
||
|
|
and shouldn't trigger range errors like "unsigned is never < 0".
