Hi, This patch xfails a float128 comparison test case on powerpc64 that fails due to a longstanding issue with floating-point compares.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684 for more information. The patch passed regression test on Power Linux platforms. Thanks Gui Haochen ChangeLog rs6000: xfail float128 comparison test case that fails on powerpc64. This patch xfails a float128 comparison test cases on powerpc64 that fails due to a longstanding issue with floating-point compares. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684 for more information. When float128 hardware is enabled (-mfloat128-hardware), xscmpuqp is generated for comparison which is unexpected. When float128 software simulation is enabled (-mno-float128-hardware), we still have to xfail the hardware version (__lekf2_hw) which finally invokes xscmpuqp. gcc/testsuite/ PR target/108728 * gcc.dg/torture/float128-cmp-invalid.c: Add xfail. patch.diff diff --git a/gcc/testsuite/gcc.dg/torture/float128-cmp-invalid.c b/gcc/testsuite/gcc.dg/torture/float128-cmp-invalid.c index 1f675efdd61..a86592b3328 100644 --- a/gcc/testsuite/gcc.dg/torture/float128-cmp-invalid.c +++ b/gcc/testsuite/gcc.dg/torture/float128-cmp-invalid.c @@ -1,5 +1,6 @@ /* Test for "invalid" exceptions from __float128 comparisons. */ /* { dg-do run } */ +/* { dg-xfail-run-if "ppc float128_hw" { ppc_float128_hw || { ppc_cpu_supports_hw && p9vector_hw } } } */ /* { dg-options "" } */ /* { dg-require-effective-target __float128 } */ /* { dg-require-effective-target base_quadfloat_support } */
