Hi,
this patch recovers location infomration in the ODR warnings.
Because location info is not attached to types but corresponding
TYPE_DECLs, we need to prevent TYPE_DECLs to be merged when
corresponding types are not merged.
To achieve this I no longer clear TREE_TYPE of TYPE_DECLs which
puts th

I thought I acked the target independent stuff a while back. What's
still waiting on review here?

It's the script that I used to identify potentially resolvable bugs. That's done
by parsing of comments and seeking for trunk/branch commits. Sample output looks

In some cases of overriding or resetting locations, we might retain
discriminator info from earlier locations, when we should take
discriminator information from the overriding location or reset it.

This libgo patch alwayss define _AT_FDCWD and IPv6MTUInfo in the
syscall package. They aren't defined by old versions of glibc, but
are required by the code in syscall_linux.go. This should fix GCC PR
88060. Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.

Hi Jakub,
I'd like to ping this patch, ok for trunk?
OK. Thanks for the patch!
Before 9.0 is released, we should also document the flag
(and the extension it supports) in the manual, and note it
in changes.html and on the Wiki. Would you also do that?

The IBM z14 POP adds an optional alignment operand to the vl, vst,

on 8 or 16 byte boundaries might get loaded or stored faster on some
models given the instruction uses the proper hint operand. A wrong
hint will hurt performanc
