Subject: [PATCH 00/11] tcg: Move tcg expanders out of line
Date: Sun, 29 Oct 2023 14:08:37 -0700 [thread overview]
Message-ID: <20231029210848.78234-1-richard.henderson@linaro.org> (raw)
This reduces the amount of code within tcg-op-common.h, and the amount
of code in the code segment full stop.
With many translators these days, we're putting the expander function
addresses into tables, or pass them to other general target-specific
expansion helpers. At present that means we get out-of-line copies of
these functions anyway. If the target is implemented with multiple
translation units, we can get multiple out-of-line copies.
This is also a necessary step in making tcg/arch/tcg-target.h private.
Top few code size reductions:
-89k qemu-system-ppc64
-88k qemu-system-aarch64
-60k qemu-system-mipsel
-50k qemu-system-arm
-42k qemu-system-riscv64
-33k qemu-system-i386
-33k qemu-system-m68k
-32k qemu-system-tricore
