Bug ID: 65126
Summary: additional_sources not defined anymore during dg-final
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
[ Reported before as PR65116. That one got hijacked for an unrelated problem. ]
When running vect-simd-clone-10.c, a file vect-simd-clone-10a.c.126t.vect is
left in the test directory.
The testcase lists vect-simd-clone-10a.c as addditional source:
...
/* { dg-additional-sources vect-simd-clone-10a.c } */
...
Then the test-case cleans up the respective tree-dump:
...
/* { dg-final { cleanup-tree-dump "vect" } } */
...
The cleanup-tree-dump calls cleanup-dump, which intends to take
additional_sources into account.
However, the global additional_sources declaration is missing, so the exists
additional_sources will always return false.
And if we add the global additional_sources declaration, it still fails,
because additional_sources is empty. It has been reset by
dg-additional-files-options, which is called by gcc_target_compile, which is
called by gcc-dg-test-1, which is called by gcc-dg-test, which is called by
dg-test as ${tool}-dg-test.
dg-test does the the dg-final-code processing after the ${tool}-dg-test so at
that point additional_sources is empty.
