# Modify the output path to avoid shared action keys.
# The issue appears to be that GCC produces absolute paths
# to system includes in .d files. These files are cached
# so the absolute paths leak into different builds. Most of the time
# this works since Azure reuses the working directory. However,
# between the daily compatibility job seems to get a different
# working directory because it is in a different pipeline.
# To make matters worse, the working directory depends on which
# job runs first afaict. There is a counter that simply gets incremented.
# Sharing between the compatibility workspace and the main workspace
# runs into the same issue.
# To sidestep this we take a md5 hash of PWD
# (this is what bazel does to determine the execroot name).
# To avoid exceeding the maximum path limit on Windows we limit the suffix to
# three characters.
