Verification todo
~~~~~~~~~~~~~~~~~
check that illegal insns on all targets don't cause the _toIR.c's to
-assert.
+assert. [DONE: amd64 x86 ppc32 ppc64 arm s390??]
check also with --vex-guest-chase-cond=yes
ditto ARM, Ld8S
-make sure IRStmt_Exit3 is completely gone.
-
all backends: iselStmt(Ist_Exit) vs iselNext: make sure that the same
JKs are handled, else it's not safe against branch sense switching
all targets: change VG_(stats__n_xindirs) to a 32 bit counter, and
empty out every now and again. Ditto VG_(stats__n_xindir_misses).
-amd64: XDirect: write const value to guest_RIP using single
-insn when the value is < 0x8000'0000
-
arm: chain_XDirect: generate short form jumps when possible
ppc: chain_XDirect: generate short form jumps when possible
