QEMU uses some tricks which make it relatively easily portable and simple while achieving good performances. -After the release of version 0.9.1, QEMU switched to a new method of -generating code, Tiny Code Generator or TCG. TCG relaxes the -dependency on the exact version of the compiler used. The basic idea -is to split every target instruction into a couple of RISC-like TCG -ops (see @code{target-i386/translate.c}). Some optimizations can be -performed at this stage, including liveness analysis and trivial -constant expression evaluation. TCG ops are then implemented in the -host CPU back end, also known as TCG target (see -@code{tcg/i386/tcg-target.inc.c}). For more information, please take a -look at @code{tcg/README}. +QEMU's dynamic translation backend is called TCG, for "Tiny Code +Generator".
