-Allow C99-depending features of libstdc++ with uClibc
-
-The libstdc++ code is fairly restrictive on how it checks for C99
-compatibility: it requires *complete* C99 support to enable certain
-features. For example, uClibc provides a good number of C99 features,
-but not C99 complex number support. For this reason, libstdc++
-completely disables many the standard C++ methods that can in fact
-work because uClibc provides the necessary functions.
-
-This patch is similar and highly inspired from
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
-a way that doesn't involve changing the configure.ac script, as
-autoreconfiguring gcc is complicated. It simply relies on the fact
-that uClibc defines the __UCLIBC__ definition.

+Subject: [PATCH] [sanitizer] Fix build with _FILE_OFFSET_BITS=64.
+
+Sanitizer source is not affected by _FILE_OFFSET_BITS in general,
+but this one file must be built with 32-bit off_t. More details in the code.

+Allow C99-depending features of libstdc++ with uClibc
+
+The libstdc++ code is fairly restrictive on how it checks for C99
+compatibility: it requires *complete* C99 support to enable certain
+features. For example, uClibc provides a good number of C99 features,
+but not C99 complex number support. For this reason, libstdc++
+completely disables many the standard C++ methods that can in fact
+work because uClibc provides the necessary functions.
+
+This patch is similar and highly inspired from
+https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
+a way that doesn't involve changing the configure.ac script, as
+autoreconfiguring gcc is complicated. It simply relies on the fact
+that uClibc defines the __UCLIBC__ definition.

+ <cltang@codesourcery.com>
+
+ Backport from mainline
+ 2015-09-22 Chung-Lin Tang <cltang@codesourcery.com>
+
+ * config/nios2/nios2.c (nios2_legitimize_address): When handling
+ 'reg + reloc' cases, allow first operand to be non-REG, and use
+ force_reg() to enforce address pattern.
