JIT: add missing endbr PR php#8774 added IBT support for jited code and passed all built-in tests in Such workloads introduce new code path and thus more "indirect branch target" |
PR php#8774 added IBT support for jitted code and passed all built-in tests in "ext/opcache/tests/jit". However, we found several "missing ENDBR" issues recently when running some real world workloads. Such workloads introduce new code path and thus more "indirect branch target" are in jited code. This fix adds missing endbr correspondingly. Signed-off-by: PeterYang12 <yuhan.yang@intel.com> Reviewed-by: chen-hu-97 <hu1.chen@intel.com> Reviewed-by: bjzhjing <cathy.zhang@intel.com>

Indirect CALL/JMP must target an ENDBR instruction or suffer #CP when Indirect Branch Tracking (IBT) is enabled.
This commit inserts somes endbr32/64 instructions which are missing in indirect branch target for jitted code.
