When using GNU ld on Solaris, a large number of asan tests SEGV, while
Solaris ld is fine. This happens inside the __tls_get_addr interceptor,
which is highly glibc-specific. Therefore this patch disables that
interceptor.

The following fixes a long-standing bug with DSE removing stores as
dead even though they are live across non-call exceptional flow.
This affects both GIMPLE and RTL DSE and the fix is similar in
making externally throwing statements uses of non-local stores.
Note this doesn't fix the GIMPLE side w

Hi Richard,
For the following (contrived) test:
void foo(int32x4_t v)
{
v[3] = 0;
return v;
}
-O2 code-gen:
foo:
fmovs1, wzr
ins v0.s[3], v1.s[0]
ret
I suppose we can instead emit the following code-gen ?
foo:
ins v0.s[3], wzr
ret
combine produces:

-fstack-protector in bpf-* targets, along with the emission of a note

In the case of the CA
Register-register move instructions that can be easily seen as
unnecessary by the human eye may remain in the compiled result.
For example:
/* example */
double test(double a, double b) {
return __builtin_copysign(a, b);
}
test:
add.n a3, a3, a3
extui a5, a5, 31, 1
s
Such operation can be done either bitwise-XOR or addition with -2147483648,
but the latter is one byte less if TARGET_DENSITY.
