+Commit a0a12c3ed057 ("asm goto: eradicate CC_HAS_ASM_GOTO") eradicates
+CC_HAS_ASM_GOTO, perf on x86 call asm_volatile_goto when compiling __GEN_RMWcc.
+However, asm_volatile_goto is not declared, which causes compilation error:

+  ^~~~~~~~~~~~~~~~~
+
+Solution:
+Define asm_volatile_goto in compiler_types.h if not declared.
+
+Currently, only x86 architecture uses asm_volatile_goto.
+Theoretically, this patch affects only the x86 architecture.
