Introduction
The QEMU team in Linaro sits inside a group known as the Toolchain Working Group (TCWG). The rest of the team spend their time working with compilers and other code generators such as GCC and LLVM. When dealing with emulation, QEMU has its own module known as the Tiny Code Generator (TCG). It shares many similarities with a compiler albeit one that works with different constraints than your typical compiler. As the code generator works on a just-in-time (JIT) basis it can’t afford to spend large amounts of time (or memory!) that a typical compiler does when optimising its output. This is especially true for code that only gets executed once or twice before being flushed out of the cache. ....
