Subject: [PATCH] s390: Fix VFLRX and WFLRX instructions
|
||||||
|
|
||||||
|
Due to a typo in s390_irgen_VFLR, the VFLR instruction behaves incorrectly
|
||||||
|
when its m3 field contains 4, meaning extended format. In that case VFLR
|
||||||
|
is also written as VFLRX (or WFLRX) and supposed to round down from the
|
||||||
|
extended 128-bit format to the long 64-bit format. However, the typo
|
||||||
|
checks for m3 == 2 instead, so the value of 4 is unhandled, causing
|
||||||
|
Valgrind to throw a specification exception.
|
||||||
|
|
||||||
|
This fixes the typo.
