+Subject: [PATCH] hppa: avoid TEXTREL in .eh_frame section
+
+Before the change hand-crafted .eh_frame section contained
+ABS relocation and caused TEXTREL tag to be emitted:
+
+```
+$ ./configure --host=hppa2.0-unknown-linux-gnu LDFLAGS=-Wl,-z,text
+$ make
+...
+/usr/libexec/gcc/hppa2.0-unknown-linux-gnu/ld:
+    read-only segment has dynamic relocations.
+```
+
+Link failure is caused by absolute address of FDEs
+encoded into .eh_frame entries.
+
+Fixed TEXTREL by using pcrel (instead of ABS) encoding
+for absolute addresses (__PIC__ code) by adding augmentation
+information ("zR" CIE type).
+
+All tests still pass on hppa2.0. The specific tests that still pass
+and exercise this code path:
+    testsuite/libffi.call/unwindtest.cc
+    testsuite/libffi.call/unwindtest_ffi_call.cc
