Subject: Display profile file name when emitting a file not found diagnostic.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c52fbfeaa5eab3037031f62a95a3cffbc793c58d;p=clang

Display profile file name when emitting a file not found diagnostic.

When a profile file cannot be opened, we used to display just the error
message but not the name of the profile the compiler was trying to open.
This will become useful in the next set of patches that introduce
GCC-compatible flags to specify profiles.
