Hi All,
This adds a new optab and IFNs for REDUC_PLUS_WIDEN where the resulting

Hi All,
The current vector extract pattern can only extract from a vector when the
position to extract is a multiple of the vector bitsize as a whole.
That means extract something like a V2SI from a V4SI vector from position 32
isn't possible as 32 is

These testcases are not depend on the ABI specification.
I pick up the minimum ABI setting so that it won't fail.
The naming of abi-* tests may be confusing, I can change the naming in the next
time.

These cases actually doesn't care about -mabi, they just need 'v' in -march.
Can you tell me how to fix these testcases for "fails on targets without
ilp32d" ?
These failures are bogus failures since if you specify -mabi=ilp32d when you
are using GNU toolchain which is build up with "--arch=ilp32

Hi
The patch is for mention Intel __bf16 support in AVX512BF16 intrinsics.
Ok for master ?
Thanks,

genericize might introduce function calls (and does on the contracts
branch), so it's safer to set this flag later.
gcc/cp/ChangeLog:
* decl.cc (finish_function): Set TREE_NOTHROW later in the function.
