| | | | | | | | | | | The availability of tb->pc will shortly be conditional. Introduce accessor functions to minimize ifdefs. Pass around a known pc to places like tcg_gen_code, where the caller must already have the value.

| | | | | | | | | | | | All of the fpu operations are defined with TCG_CALL_NO_WG, but they all modify FCSR0. The most efficient way to fix this is to remove cpu_fcsr0, and instead use explicit load and store operations for the two instructions that manipulate that value.
