test/DebugInfo/MIR/X86/kill-after-spill.mir - llvm-project/llvm - Git at Google

 # RUN: llc -run-pass=livedebugvalues -o - %s | FileCheck %s
 #
 # This test is used to acknowledge situation when spill register is killed
 # in instruction after the spill occurs.
 # Generated MIR is changed in order to test case when instruction after
 # possible spill, say instruction B, kills register different than than
 # the one that is used in possible spill, say instruction A. In that case
 # the instruction A is not recognized as spill. Changed instructions are
 # commented in MIR below.
 #
 # ...
 # A - possible spill instruction with register R2
 # B - instruction that kills R3
 # ...
 #
 # CHECK: bb.1.if.end:
 # CHECK: DBG_VALUE $rbp, 0, !37, !DIExpression(DW_OP_constu, 44, DW_OP_minus)
 # CHECK-NOT: DBG_VALUE $rbp, 0, !36, !DIExpression(DW_OP_constu, 48, DW_OP_minus)
