Since it is a regression, by all means update the branches. We

Hi!
The 991213-3.c testcase ICEs on aarch64-linux with -mabi=ilp32
since wide-int merge. The problem is that
x = convert_memory_address (Pmode, x)
is used twice on a VOIDmode CONST_INT, which is wrong.
For non-VOIDmode rtl the second convert_memory_address
is a NOP, but for VOIDmode the second
As suggested by Andreas in the PR, the simplest fix for this problem is
to disable the various trunc* patterns for TARGET_COLDFIRE. That's
precisely what this patch does.
Built cross compilers with and without the m68k.md hunk. Verified the
test failed without the m68k.mk hunk and passed
Hi!
This patch optimizes away TRUNC_MOD_EXPR by constant second argument
(if not 0 and not type's minimum) if the range of the first argument
is already known to be [-op1 + 1, op1 - 1] or its subset.

Hi Jakub,
I am asking if we plan to merge the TSAN runtime from the LLVM tree soon, or if
it is better to cherry pick
specific changes from there.
I am especially interested in fixing these two issues, but there may be other
important improvements too:

As mentioned in the PR, HPUX doesn't have scalbln, but does have ldexp and
that function is already used in gcj-dump, so supposedly it is more portable
to use ldexp. Also in glibc it is defined in libc in addition to libm.

As mentioned in the PR, giving up for all vector mode extensions

of the extended value is the original value, for vectors this is not true,
thus the old value is lost. Which

I was confused by the description of -Wbad-function-cast. It talks
