Hello,
Test case g++.dg/torture/20141013.C (added
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01190.html) triggers the
warning
--
20141013.C:45:23: warning: width of 'tree_base::code' exceeds its type
--
on arm-none-eabi.
The code specifies a bitfield of size 16 with an enum as the underlying
type. On arm-none-eabi, enums are packed by default (-fshort-enums) so
the bitfield is oversized and the warning is correct.
This patch adds -fno-short-enums to the compiler options for the test case.
Testing: Ran g++.dg/torture/dg-torture.exp for arm-none-eabi and
arm-none-linux-gnueabihf.
