[PATCH 4/6] Andes nds32: testsuite modifications for nds32 target.

[PATCH 4/6] Andes nds32: testsuite modifications for nds32 target.

[Chung-Ju Wu]

[-- Attachment #1: Type: text/plain, Size: 1297 bytes --]

Hi,

This patch consists of testsuite changes, including skip cases,
expected fail cases, and __nds32__ specific cases.
In additon, we also add checking in lib/target-supports.exp
because profiling is not available for nds32*-*-elf target.

Skipping these tests seems dubious - you should fix the assembler bug that 
it fails to support extended identifiers instead of skipping the tests.

I don't see any sign of new architecture-specific testcases.  It's 
generally a good idea to have such tests, to verify that built-in 
functions and attributes and options work as expected, that the 
diagnostics in the back end are given for the invalid input you expect to 
give such diagnostics, etc.  (Of course the gcc.target/nds32 testsuite 
will grow over time with testcases for bugs in such architecture-specific 
functionality that get found and fixed over time.)

Hi, Joseph,

Sorry for the late revised patch.
We have completed all of it based on your review comments.

We have cooperated with toolchain engineers.
These three cases now are able to tested for nds32 target.

Thanks for the comments.  We added several new target-specific testcases
under gcc.target/nds32, including basic main execution and built-in
functions verification.


A revised patch is provided and here is a summary:

   1. The extend identifiers testcases are supposed to be tested.
   2. Add preliminary nds32-specific testcases.

It has been a while since last v2 patch.
So I create a new v3 patch to resolve some conflicts
on testcases with current trunk.

there is no further comment to the patch.

Is it OK to apply on the trunk?
