[llvm-dev] can llvm-lit pass output of one RUN command as an argument to another RUN command

[don hinton via llvm-dev]

Is there a way to do this with llvm-lit, i.e., use the equivalent of
backticks?

foo takes a single argument, but doesn't read from stdin.

// RUN foo some_arg > %t; FileCheck %s < %t
// RUN foo `cat %t` | FileCheck --check-prefix=INVERSE

// CHECK: {{^[0-9]+$}}
// INVERSE: some_arg

thanks...
don
