Subject: [PATCH-for-10.1 05/12] tcg: Use TCGContext::insn_start_words in tcg_gen_insn_start()
Date: Wed, 19 Mar 2025 14:44:59 +0100 [thread overview]
Message-ID: <20250319134507.45045-6-philmd@linaro.org> (raw)
In-Reply-To: <20250319134507.45045-1-philmd@linaro.org>
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 = 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.
