Subject: [PATCH v3 00/30] tcg: Simplify temporary usage
Date: Fri, 24 Feb 2023 22:59:15 -1000 [thread overview]
Message-ID: <20230225085945.1798188-1-richard.henderson@linaro.org> (raw)
The biggest pitfall for new users of TCG is the fact that "normal"
temporaries die at branches, and we must therefore use a different
"local" temporary in that case.
The following patch set changes that, so that the "normal" temporary
is the one that lives across branches, and there is a special temporary
that dies at the end of the extended basic block, and this special
case is reserved for tcg internals.
Patches lacking review:
07-tcg-Add-liveness_pass_0.patch
10-tcg-Use-tcg_constant_i32-in-tcg_gen_io_start.patch
14-tcg-Use-tcg_constant_ptr-in-do_dup.patch
17-tcg-Don-t-re-use-TEMP_TB-temporaries.patch
30-tcg-Update-docs-devel-tcg-ops.rst-for-temporary-c.patch
