+Subject: [PATCH] Fix trampolines search code for conditional branches
+
+For conditional branches that need more than one trampoline to reach its
+target assembler couldn't always find suitable trampoline because
+post-loop condition check was placed inside the loop, resulting in
+premature loop termination. Move check outside the loop.
+
+This fixes the following build errors seen when assembling huge files
+produced by gcc:
+ Error: jump target out of range; no usable trampoline found
+ Error: operand 1 of 'j' has out of range value '307307'
+
+2014-11-25 Max Filippov <jcmvbkbc@gmail.com>

+gas/
+ * config/tc-xtensa.c (search_trampolines): Move post-loop
+ condition check outside the search loop.
+
+gas/testsuite/
+ * gas/xtensa/trampoline.d: Add expected output for branches.
+ * gas/xtensa/trampoline.s: Add test case for branches.
