[Qemu-devel] Storing instructions executed in CPUState

[James Greensky]

Hello, I am attempting to fold a cache model into Qemu.  For this I need to store the instructions executed between actual lds/sts to Qemu memory, for performance reasons.  I figured that a buffer in the CPUState could accommodate this requirement, however tcg only gives the ability to ld/st from host memory at constant offsets.  Is there a better solution to this problem than adding new ld/st instructions to tcg that take a computed offset? Thx, James
