[0/6] nvptx testsuite patches

[0/6] nvptx testsuite patches

[Bernd Schmidt]

This series modifies a large number of tests in order to clean up 
testsuite results on nvptx. The goal here was never really to get an 
entirely clean run - the target is just too different from conventional 
ones - but to be able to test the compiler sufficiently to be sure that 
it's in good shape for use in offloading. Most of the patches here add 
annotations for use of features like alloca or indirect jumps that are 
unsupported on the target.

Examples of things that still cause failures are things like dots in 
identifiers, use of constructors (which is something I want to look 
into), certain constructs that trigger bugs in the ptxas tool, and lots 
of undefined C library functions.

[1/6] nvptx testsuite patches: alloca

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 276 bytes --]

This deals with uses of alloca in the testsuite. Some tests require it 
outright, others only at -O0, and others require it implicitly by 
requiring an alignment for stack variables bigger than the target's 
STACK_BOUNDARY. For the latter I've added explicit xfails.

[2/6] nvptx testsuite patches: typed assembly

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 339 bytes --]

Since everything in ptx assembly is typed, K&R C is problematic. There 
are a number of testcases that call functions with the wrong number of 
arguments, or arguments of the wrong type. I've added a new feature, 
untyped_assembly, which these tests now require. I've also used this for 
tests using builtin_apply/builtin_return.

I'd kind of prefer to see the tests fixed, but I can live with this.

FWIW, the PA (32-bit SOM) is very sensitive to this stuff as well, 
though the linker will detect and correct most of these problems.  The 
PTX model doesn't give you the option to correct this stuff during the 
link phase

Most of these are quite old, and it seems likely that they should be 
kept as they are for test coverage - it's desirable to know that the 
compiler doesn't crash when a K&R function is called with varying 
numbers of arguments for example.

Just a note that I'm assuming that your mail was an approval and 
checking this in.

[3/6] nvptx testsuite patches: stdio

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 406 bytes --]

Some tests use stdio functions which are unavaiable with the cut-down 
newlib I'm using for ptx testing. I'm somewhat uncertain what to do with 
these; they are by no means the only unavailable library functions the 
testsuite tries to use (signal is another example). Here's a patch which 
deals with parts of the problem, but I wouldn't mind leaving this one 
out if it doesn't seem worthwhile.

Tests probably shouldn't be using stdio anyway, except perhaps for the 
wrapper used when we run remotes and such to print the PASS/FAIL message.

One could argue a better direction would be to change calls into stdio 
to instead call some other function defined in the same .c file.  That 
"other function" would be marked as noinline.  That would help minimize 
the possibility of compromising the test.

Here's a patch which deals with parts of the problem, but I wouldn't mind leaving this one out if it doesn't seem worthwhile.

So, it is nice if an entire newlib port can be done, then, you don’t have to worry about subsets of it.

I think the patch is Ok, I would change:

+#ifndef __nvptx__
   fprintf (stderr, "Test failed: %s\n", msg);
+#endif

to just comment out the line.

If you want to try your hand at removing stdio in some fashion, you can try, I am skeptical that there is a meaningful way to do that and it seems larger and harder then the patch you have.  The usual fashion I would recommend would be a stub library for testing that simply disappears such calls as uninteresting.  int fpritnf (…) { return 0; } would go a long way.  For test cases that someone care about what fprintf actually does, those can be marked as stdio and likely, those would be a far smaller set to so mark.

That's probably true, but not all functionality can be supported - 
there's no way to do things like signal or setjmp on this target. Rather 
than compile in stuff that doesn't work I thought it better to have link 
errors.

Hmm, that seems like an ide, a nvptx libteststubs.a. That might clean up 
additional noise from the results.

[4/6] nvptx testsuite patches: xfails and skips

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 184 bytes --]

Some things don't fit into nice categories that apply to a larger set of 
tests, or which are somewhat random like ptxas tool failures. For these 
I've added xfails and skips.

More ptx tooling failures than I'd expect.  I'll leave it up to you 
whether or not to push on NVidia to fix some of those failures.  The 
timeouts seem particularly troublesome.

I think this is fine.

All I can say is that we've reported them.

[5/6] nvptx testsuite patches: jumps and labels

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 324 bytes --]

This deals with tests requiring indirect jumps (including tests using 
setjmp), label values, and nonlocal goto.

A subset of these tests uses the NO_LABEL_VALUES macro, but it's not 
consistent across the testsuite. The feature test I wrote tests whether 
that is defined and returns false for label_values if so.

NO_LABEL_VALUES probably hasn't been consistently kept up-to-date as the 
focus of the project has moved a bit away from embedded.  That code also 
predates the push for check_effective_target_*.

OK for the trunk.

[6/7] Random tweaks

[Bernd Schmidt]

[-- Attachment #1: Type: text/plain, Size: 577 bytes --]

This tweaks a few tests so that we don't have to skip them.  This is 
mostly concerned with declaring main properly, or changing other 
declarations where the test does not seem to rely on the type mismatches.

I've also included one example of changing a function name to not be 
"call", ptxas seems to have a bug that makes it not allow this function 
name. If that doesn't seem too awful I'll have a few more tests to fix 
up in this way.

There'll be a 7th patch, not because I can't count, but because I didn't 
follow a consistent naming scheme for the patches.

Are any of these obsoleted by Marek's work around gnu11?  If not, 
they're all fine for the trunk.

I think Marek went only for stuff reported as failures in the testsuite.
gcc.c-torture/compile/ defaults to -w I think, supposedly execute/ too,
so C11 incompatibilities in there might not have been reported.

That's right.

I can remove the -w and fix C89/C11 incompatibilities, if anyone
thinks it's worth it.

I’d leave the -w, no point in spending much time worrying about it.  The -w is so that no one has to spend time worrying about it.  If you want to fix the language to avoid the warnings when -w isn’t given, feel free.

Yea. When I first looked at PTX, my thought was to use the existing 
testsuite, to the extent possible, to shake out the initial code 
generation issues.  There's just some things that would require heroic 
effort to make work and they aren't really a priority for PTX.

So I've got not problem conceptually with the direction this work is taking.
