runtime: TestStackBarrierProfiling failing on ppc64, ppc64le and mips64 #13334

I'm working on getting access to a ppc64 box I can debug this on (the one I had access to went away). My completely unsubstantiated guess is that GODEBUG=gcstackbarrierall=1 just doesn't work on ppc64. It chews up a lot of stack space and it may just chew up too much on ppc64. |

It looks like my guess was right, so I'll probably just disable this test on ppc64 (it's not worth making gcstackbarrierall work on ppc64). The mips64 failure looks like the test is catching a genuine bug. |

This test depends on GODEBUG=gcstackbarrierall, which doesn't work on ppc64. Updates golang#13334. Change-Id: Ie554117b783c4e999387f97dd660484488499d85 Reviewed-on: https://go-review.googlesource.com/17120 Run-TryBot: Austin Clements <[email protected]> Reviewed-by: Russ Cox <[email protected]>

624d798 fixed the ppc64 bug and the mips64 bug is a dup of #12528. |
