These are from some tests I recently committed, I obviously missed this combo (testing with older dejagnu).. I think I've updated my dejagnu versions all over the place for other reasons. Do you consider this a non-typical corner case with older dejagnu, or should I try to explicitly check for this in the future? Similar/same changes below. These changes all seem reasonable. lgtm, thanks -Will > > diff --git a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-int.c b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-int.c > index ea737466a58..c40e1a3a0f7 100644 > --- a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-int.c > +++ b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-int.c > @@ -2,8 +2,9 @@ > Test of vec_xl_sext and vec_xl_zext (load into rightmost > vector element and zero/sign extend). */ > > -/* { dg-do compile {target power10_ok} } */ > -/* { dg-do run {target power10_hw} } */ > +/* { dg-do run { target power10_hw } } */ > +/* { dg-do compile { target { ! power10_hw } } } */ > +/* { dg-require-effective-target power10_ok } */ > /* { dg-require-effective-target int128 } */ > > /* Deliberately set optization to zero for this test to confirm > diff --git a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-longlong.c b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-longlong.c > index cd155c2013d..405b4245f8e 100644 > --- a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-longlong.c > +++ b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-longlong.c > @@ -2,8 +2,9 @@ > Test of vec_xl_sext and vec_xl_zext (load into rightmost > vector element and zero/sign extend). */ > > -/* { dg-do compile {target power10_ok} } */ > -/* { dg-do run {target power10_hw} } */ > +/* { dg-do run { target power10_hw } } */ > +/* { dg-do compile { target { ! power10_hw } } } */ > +/* { dg-require-effective-target power10_ok } */ > /* { dg-require-effective-target int128 } */ > /* { dg-options "-mdejagnu-cpu=power10 -O3 -save-temps" } */ > > diff --git a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-short.c b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-short.c > index 68fdcdcea37..837ba79c9ab 100644 > --- a/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-short.c > +++ b/gcc/testsuite/gcc.target/powerpc/vsx-load-element-extend-short.c > @@ -2,8 +2,9 @@ > Test of vec_xl_sext and vec_xl_zext (load into rightmost > vector element and zero/sign extend). */ > > -/* { dg-do compile {target power10_ok} } */ > -/* { dg-do run {target power10_hw} } */ > +/* { dg-do run { target power10_hw } } */ > +/* { dg-do compile { target { ! power10_hw } } } */ > +/* { dg-require-effective-target power10_ok } */ > /* { dg-require-effective-target int128 } */ > > /* Deliberately set optization to zero for this test to confirm > diff --git a/gcc/testsuite/gcc.target/powerpc/vsx-store-element-truncate-char.c b/gcc/testsuite/gcc.target/powerpc/vsx-store-element-truncate-char.c > index 45c49547d66..3049b1c2c28 100644 > --- a/gcc/testsuite/gcc.target/powerpc/vsx-store-element-truncate-char.c > +++ b/gcc/testsuite/gcc.target/powerpc/vsx-store-element-truncate-char.c > @@ -1,8 +1,9 @@ > /* > Test of vec_xst_trunc (truncate and store rightmost vector element) */ > > -/* { dg-do compile {target power10_ok} } */ > -/* { dg-do run {target power10_hw} } */ > +/* { dg-do run { target power10_hw } } */ > +/* { dg-do compile { target { ! power10_hw } } } */ > +/* { dg-require-effective-target power10_ok } */ > /* { dg-require-effective-target int128 } */ > /* Deliberately set optization to zero for this test to confirm > the stxvr*x instruction is generated.

I don't know what version of dejagnu introduced the fix, but probably newer than our minimum required version. Thanks, Segher

(Just FMI.) Yes, it does. Older dejagnu takes the last action regardless of the target selector success. Newer dejagnu uses the last action of a line with a successful target selector. commit 569f8718b534a2cd9511a7d640352eb0126ff492 Author: Dominik Vogt <vogt@linux.vnet.ibm.com> Date: Mon Mar 28 17:31:07 2016 +1100 * dg.exp (dg-do): Do not change the previously selected action if a de-selected dg-do is encountered.
