Subject: [PATCH 045/157] [Backport][SME] aarch64: Add a result_mode helper
|
||
|
|
function
|
||
|
|
|
||
|
|
Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=a1bc121c00e30bd1bdaa62d87cbe64eb88e74f45
|
||
|
|
|
||
|
|
SME will add more intrinsics whose expansion code requires
|
||
|
|
the mode of the function return value. This patch adds an
|
||
|
|
associated helper routine.
