Hi, Andrew
Thanks for this series of patches to improve do_store_flag. Unfortunately
this specific patch in the series has caused a bootstrap failure on
powerpc-aix. I bisected this failure to this specific patch. Note that I
am building as 32 bit, so this could be a specific issue about bit size.
* expr.cc (fold_single_bit_test): Rename to ...
(expand_single_bit_test): This and expand directly.
(do_store_flag): Update for the rename function.
Did this include the fix I did for big-endian at
r14-1022-g7f3df8e65c71e5 ? I had found that I broke big-endian last
night with that patch and pushed the fix once I figured out what I did
wrong.
If you already tried post the fix, I will try to look into it as soon
as possible.
FWIW, the various failing hosts from yesterday in my tester have all
returned to successful builds after the BE fixes. m32r, iq2000, moxie,
sh3eb, h8300.
There's a very reasonable chance the PPC bug is the same underlying issue.
