Subject: Driver: Add a gcc equivalent triple to the list of triples to search
|
|
|
c67ce2 |
|
|
|
c67ce2 |
There are some gcc triples, like x86_64-redhat-linux, that provide the
|
|
|
c67ce2 |
same behavior as a clang triple with a similar name (e.g.
|
|
|
c67ce2 |
x86_64-redhat-linux-gnu). When searching for a gcc install, also search
|
|
|
c67ce2 |
for a gcc equivalent triple if one exists.
