In tb_gen_code() we set TCGContext::insn_start_words to
TARGET_INSN_START_WORDS:
290 TranslationBlock *tb_gen_code(...)
293 {
...
351 tcg_ctx->insn_start_words =3D TARGET_INSN_START_WORDS;
This definition is expanded to:
11 # define TARGET_INSN_START_WORDS (1 + TARGET_INSN_START_EXTRA_WORDS)
Directly use the identical tcg_ctx->insn_start_words variable.
