H A D | tcg.c | abebf925 Tue May 08 14:18:59 CDT 2018 Richard Henderson <richard.henderson@linaro.org> tcg: Limit the number of ops in a TB In 6001f7729e12 we partially attempt to address the branch displacement overflow caused by 15fa08f845. However, gcc/testsuite/gcc.target/aarch64/advsimd-intrinsics/vqtbX.c is a testcase that contains a TB so large as to overflow anyway. The limit here of 8000 ops produces a maximum output TB size of 24112 bytes on a ppc64le host with that test case. This is still much less than the maximum forward branch distance of 32764 bytes.
