TL;DR:
I have an issue where if I have a .so linked with -static-lib* making
all STL symbols private, and if I throw an exception out of that .so to
be caught by the caller, then I get a SIGABRT from a gcc_assert() down
in the guts of the signal handling:
#0 0x7773a428 in raise () from /l

You need to work out which ABIs (-m32, -mx32, -m64) this testing is
meaningful for. Then, allow both x86_64- and i?86- targets, together w

So, hrm, are there any passes we *want* to do in non-cfglayout mode?

Hi Robin,
I thought I'd share some of what I've run into while doing similar
things for the rs6000 target.
First off, be aware that glibc does some macro expansion things to try
to handle 1/2/3 byte string operations in some cases.

Hi,
When examining the performance of some test cases on s390 I realized
that we could do better for constructs like 2-byte memcpys or
2-byte/4-byte memsets. Due to some s390-specific architectural
properties, we could be faster by e.g. avoiding excessive unrolling and
using dedicated memory instr
