[PATCH 00/11] tcg: Move tcg expanders out of line
Posted by Richard Henderson 1 year ago
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
