Bug ID: 80092
Summary: Add effective-target keywords for unsupported nvptx
features
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Atm, when running for target nvptx, we run into unsupported features in the
tests.
F.i. in the g++ testsuite:
...
$ grep -c "sorry, unimplemented:" g++.log
12693
...
more in detail:
...
$ grep "sorry, unimplemented:" g++.log | sed 's/.*sorry, unimplemented://' |
dos2unix | sort -u
converting lambda which uses '...' to function pointer
global constructors not supported on this target
global destructors not supported on this target
indirect jumps are not available on this target
mangling __underlying_type
non-trivial designated initializers not supported
passing arguments to ellipsis of inherited constructor 'B::B(int, ...)
[inherited from A]'
target cannot support alloca.
target cannot support nonlocal goto.
...
All those tests are FAILs, while they should be UNSUPPORTED.
In principle, having those as FAILs is not a problem when regression testing.
We can compare tests results, and only look at changes.
But it's better to introduce effective-target keywords for those features, and
mark the tests as such. That will reduce the noise rate because of unsupported
features being used or not due to code generation changes.
