Subject: Convert SampleProfile pass into a Module pass.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=14180dd76f533942e2400f0f7d482e768b30443e;p=clang

Convert SampleProfile pass into a Module pass.

Eventually, we will need sample profiles to be incorporated into the
inliner's cost models.  To do this, we need the sample profile pass to
be a module pass.

This patch makes no functional changes beyond the mechanical adjustments
needed to run SampleProfile as a module pass.
