# We do not support the call site info for the target now, so we use the experimental option (-emit-call-site-info -debug-entry-values).

# RUN: llc -emit-call-site-info -debug-entry-values -run-pass=none -verify-machineinstrs -o - %s | FileCheck %s

# Verify that it is possible to read and write MIR where a callSites entry
# points to a call residing in a bundle. The offset should point to the call
# instruction, rather than the bundle head.

# CHECK: name: caller
# CHECK: callSites:
# CHECK-NEXT: bb: 0, offset: 3, fwdArgRegs:
# CHECK-NEXT:   arg: 0, reg: '$r0'

# XXX: Please note that at the time of creating this test the Hexagon target
# did not support call site information, so the "callSites" array has been
# manually added.
