From 8298ec2d6299a95d2920cb8ee993ac6c5e604097 Mon Sep 17 00:00:00 2001 From: Andrzej Warzynski Date: Thu, 7 Jan 2021 17:49:38 +0000 Subject: [PATCH] [flang][driver] Copy input files into a temp dir when testing The following frontend driver invocation will generate 2 output files in the same directory as the input files: ``` flang-new -fc1 input-1.f input-2.f ``` This is the desired behaviour. However, when testing we need to make sure that we don't pollute the source directory. To this end, copy test input files into a temporary directory.
