[Bug testsuite/63175] [4.9/5 regression] FAIL: gcc.dg/vect/costmodel/ppc/costmodel-bb-slp-9a.c scan-tree-dump-times slp2 basic block vectorized using SLP 1

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63175 --- Comment #32 from David Edelsohn dje at gcc dot gnu.org --- So currently on a tie we don't vectorize basic-blocks (same with GCC 4.8). That's kind of arbitrary, but given instruction encoding size on x86 for example it makes sense.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63175 --- Comment #27 from David Edelsohn dje at gcc dot gnu.org --- The vector alignment cost varies with processor implementation, not defined by the architecture. Bill has a patch that adjusts unaligned vector cost for POWER8, which may affect

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65240 --- Comment #8 from David Edelsohn dje at gcc dot gnu.org --- Comment #7 means that it fails with -mcpu=power8. What feature really exposes the problem? -mcpu=power7? -mcpu=power6? -mcpu=power5? Thanks, David

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65138 --- Comment #7 from David Edelsohn dje at gcc dot gnu.org --- Allowing users to specify -mcpu=powerpc64le is all well and good, but if TARGET_DEFAULT is set, it should not be gratuitously overridden in rs6000_option_override. The logic

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65155 --- Comment #1 from David Edelsohn dje at gcc dot gnu.org --- This is caused by AIX keeping the plugin shared object cached after running the testsuite. I guess this means the best solution is deleting the library before relinking it.
