+From b58caef7fd620408be9239ac24ea89d5bc84f30b Mon Sep 17 00:00:00 2001
+From: Sergei Trofimovich <slyfox@gentoo.org>
+Date: Sat, 17 Feb 2018 19:00:40 +0000
+Subject: [PATCH 2/2] ia64: fix small struct return
+
+This change fixes libffi.call/struct10.c failure on ia64:
+FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O0 execution test
+
+.Lst_small_struct handles returns for structs less than 32 bytes
+(following ia64 return value ABI [1]). Subroutine does roughly the
+following:
+
+```
+    mov [sp+0]  = r8
+    mov [sp+8]  = r9
+    mov [sp+16] = r10
+    mov [sp+24] = r11
+    memcpy(destination, source=sp, 12);
+```
+
+The problem: ia64 ABI guarantees that top 16 bytes of stack are
+scratch space for callee function. Thus it can clobber it. [1]
+says (7.1 Procedure Frames):
+"""
+* Scratch area. This 16-byte region is provided as scratch storage
+  for procedures that are called by the current procedure. Leaf
+  procedures do not need to allocate this region. A procedure may
+  use the 16 bytes at the top of its own frame as scratch memory,
+  but the contents of this area are not preserved by a procedure call.
+"""
+
+In our case 16 top bytes are clobbered by a PLT resolver when memcpy()
+is called for the first time. As a result memcpy implementation reads
+already clobbered data frop top of stack.
+
+The fix is simple: allocate 16 bytes of scrats space prior to memcpy()
+call.
