+Date: Thu, 20 Mar 2025 09:32:31 +0000
+Subject: [PATCH] Fix GCN SIMD libm bug
+
+Since January, GCC has been miscompiling Newlib libm on AMD GCN due to
+undefined behaviour in the RESIZE_VECTOR macro.  It was "working" but expanding
+the size of a vector would no longer zero the additional lanes, as it expected.
+
+See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119325
