Hi! Another testcase that is failing on powerpc64-linux. The test expects a diagnostics when float64 && float128 or in another spot when float32 && float128. Now, float128 effective target is satisfied on powerpc64-linux, despite __CPP_FLOAT128_T__ not being defined, because one needs to add some extra options for it. I think 32-bit arm has similar case for float16.
Tested on x86_64-linux, i686-linux, powerpc64-linux -m32/-m64 and powerpc64le-linux, committed to trunk as obvious, queued for 13.2. 2023-04-25 Jakub Jelinek <ja...@redhat.com> * g++.dg/cpp23/ext-floating2.C: Add dg-add-options for float16, float32, float64 and float128. --- gcc/testsuite/g++.dg/cpp23/ext-floating2.C.jj 2022-09-27 08:03:27.116982776 +0200 +++ gcc/testsuite/g++.dg/cpp23/ext-floating2.C 2023-04-25 15:27:09.204863869 +0200 @@ -1,6 +1,10 @@ // P1467R9 - Extended floating-point types and standard names. // { dg-do compile { target c++23 } } // { dg-options "" } +// { dg-add-options float16 } +// { dg-add-options float32 } +// { dg-add-options float64 } +// { dg-add-options float128 } #include "ext-floating.h" Jakub
