Subject: [NewPM][PassInstrumentation] IR printing support from clang driver
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9cee9cdce2c7cf4c9f249347dd9e8d77f16ade96;p=clang

[NewPM][PassInstrumentation] IR printing support from clang driver

Summary: https://reviews.llvm.org/D50923 enabled the IR printing support for the new pass manager, but only for the case when `opt` tool is used as a driver. This patch is to enable the IR printing when `clang` is used as a driver.
