# REQUIRES: x86

## Test that DTLTO options are passed correctly to the distributor and
## remote compiler.

RUN: rm -rf %t && split-file %s %t && cd %t

RUN: opt -thinlto-bc foo.ll -o foo.o

## Note: validate.py does not perform any compilation. Instead, it validates the
## received JSON, pretty-prints the JSON and the supplied arguments, and then
## exits with an error. This allows FileCheck directives to verify the
## distributor inputs.
