Emulated cache flush throws away the whole buffer

When the emulation calls the newcpu.c/flush_icache() function then it falls back to the flush_icache_hard() function and throws away the whole compiled code buffer.

In the x86 implementation the checksums for the blocks are used for comparing the current code in memory to the source of the compiled code and if it was not changed then the block is kept after the cache flush.

Also the dormant flag can be used for preserving the original compiled code, it marks the blocks which are falling into the ROM memory area, so these cannot change.
