From 100b5e0170e86661aaf830869be930a1a201ed08 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sat, 14 Sep 2013 15:57:22 -0700 Subject: tcg: Put target helper data into an array. One call inside of a loop to tcg_register_helper instead of hundreds of sequential calls. Presumably more icache and branch prediction friendly; resulting binary size mostly unchanged on x86_64, as we're trading 32-bit rip-relative references in .text for full 64-bit pointers in .rodata.
