Subject: Partial revert of r353952: [HIP] Handle compile -m options and propagate into LLC
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=943cfd81c5193f7eca99b3e65d1107658241a7a4;p=clang

Partial revert of r353952: [HIP] Handle compile -m options and propagate into LLC

Remove comments and tests about passing -mcode-object-v3 to driver since it does
not work. Other -m options are OK.

Also put back -mattr=-code-object-v3 since HIP is still not ready for code object
v3.
