Subject: Assert that Process::FindInEnvPath() is passed a relative path.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=941813305546c1ee937e6aaeb96b541aa9097295;p=llvm

Assert that Process::FindInEnvPath() is passed a relative path.

It misbehaves with absolute paths. (So does path::append().)
Goes with clang r235787.
