+Subject: [PATCH 8/9] x86: Add 'V' register operand modifier (documentation)
+
+Add 'V', a special modifier which prints the name of the full integer
+register without '%'. For
+
+extern void (*func_p) (void);
+
+void
+foo (void)
+{
+ asm ("call __x86_indirect_thunk_%V0" : : "a" (func_p));
+}
+
+it generates:
+
+foo:
+ movq func_p(%rip), %rax
+ call __x86_indirect_thunk_rax
+ ret
