From dc41aa7d34989b552efe712ffe184236216f960b Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 20 Oct 2017 00:30:24 -0700 Subject: tcg: Remove GET_TCGV_* and MAKE_TCGV_* The GET and MAKE functions weren't really specific enough. We now have a full complement of functions that convert exactly between temporaries, arguments, tcgv pointers, and indices. The target/sparc change is also a bug fix, which would have affected a host that defines TCG_TARGET_HAS_extr[lh]_i64_i32, i.e. MIPS64. Reviewed-by: Emilio G.
