Subject: [PR 66854 powerpc regression] Fix RTEMS powerpc build issue
To: gcc-patches at gcc.gnu.org, dje.gcc at gmail.com
My IEEE 128-bit floating point infrastructure patches resulted in a
segmentation violation on RTEMS when building libgcc. I had put a test using a
type tree variable before the test whether it was NULL or not.
This patch bootstraps on 64-bit Linux, and it also fixes the problem in
question when building a RTEMS compiler. Can this patch be installed if it
causes no further regressions for RTEMS?

null before IEEE 128-bit floating point support patch.
