Bug ID: 88310
Summary: [9 Regression] Guarded profile use + reorder tests
have become UNSUPPORTED
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
Target Milestone: ---
A new warning was added in 264657 that fires if the profile count data file is
missing when -fprofile-use is enabled.
There's a test in testsuite/lib/target-supports.exp that is then caused to fail
with the new warning, which causes guarded tests to become UNSUPPORTED. See
below.
What's not clear is why the regression testers apparently didn't pick this up
(I noticed because it causes a false progression on Darwin)
