"""
|
||
|
|
Script to assemble a text IR file and run FileCheck on the output with the
|
||
|
|
provided arguments. The first 2 arguments are the paths to the llvm-as and
|
||
|
|
FileCheck binaries, followed by arguments to be passed to FileCheck. The last
|
||
|
|
argument is the text IR file to disassemble.
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
python llvm-as-and-filecheck.py
|
||
|
|
<path to llvm-as> <path to FileCheck>
|
||
|
|
[arguments passed to FileCheck] <path to text IR file>
