Michael,
Works with GCC v10.
I backported this patch for the Alpine[1] gcc v10 and then I used the libgcc
package to test. I have used the binutils v2.35.1 with the warning of the GNU
Attribute and the

In addition to ibm-ldouble.c, the following functions set the gnu attribute #4

ibm-ldouble.c. That is the module that has the extended IBM 128-bit support in
