Subject: [PATCH 5/6] sparc: Fix sparc64 memmove length comparison (BZ 31266)
|
||
|
|
|
||
|
|
The small counts copy bytes comparsion should be unsigned (as the
|
||
|
|
memmove size argument). It fixes string/tst-memmove-overflow on
|
||
|
|
sparcv9, where the input size triggers an invalid code path.
|
||
|
|
|
||
|
|
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
|
||
|
|
|
||
|
|
(cherry picked from commit 926a4bdbb5fc8955570208b5571b2d04c6ffbd1d)
