I've collected some data running X86_64 SPECINT2006 guest on
qemu-system-x86_64. Indirect branches and calls are responsible for an
average 16.49% of all the code cache exits on the measured workloads with
the highest of 33.2% in 464.h264ref.
Every code cache exit is followed by a TB lookup and c
Hi
I would like to implement a well known indirect branch optimization named
Polymorphic Inline Caching (PIC) in QEMU. PIC relies on software
speculation on the likely target of the indirect branch to speed up its
dispatch.
Currently, QEMU generates a EOB (end of block) after indirect branches an
