PowerPC64 little-endian fixes: AltiVec tests
|
|
|
7ab123 |
|
|
|
7ab123 |
A couple of AltiVec tests fail spuriously on powerpc64le-linux, because
|
|
|
7ab123 |
they compare against an incorrect pattern. Note that those tests already
|
|
|
7ab123 |
contain little-endian variants of the patterns, but those seem to have
|
|
|
7ab123 |
bit-rotted a bit: when outputting a vector, GDB no longer omits trailing
|
|
|
7ab123 |
zero elements (as it used to do in the past).
|
|
|
7ab123 |
|
|
|
7ab123 |
This patch updates the pattern to the new GDB output behavior.
|
|
|
7ab123 |
|
|
|
7ab123 |
In addition, the patch updates the endian test to use the new
|
|
|
7ab123 |
gdb_test_multiple logic instead of gdb_expect.
