[Qemu-devel] [PATCH v3 24/50] plugin-gen: add plugin_insn_append

[Alex Bennée]

From: "Emilio G. Cota" <address@hidden>

By adding it to plugin-gen's header file, we can export is as
an inline, since tcg.h is included in the header (we need tcg_ctx).

Signed-off-by: Emilio G. Cota <address@hidden>
