There doesn't seem to be any reason for this file to have a .c

The library specializations for __int128 and __float128 are not
defined when __STRICT_ANSI__ is defined, so some tests fail when
compiled with -std=c++NN rather than -std=gnu++NN. This lets them
pass.

I'm moving { dg-error "..." "" { target *-*-* } NN } to line NN so it
can just be { dg-error "..." } with an implied line number. That makes
the tests less fragile if the test changes and the line moves.

This test uses \n inside a raw string literal, which is not a newline
but just a backslash followed by 'n', and that's not a valid POSIX BRE
so the test fails when run with -std=c++11 rather than -std=gnu++11.
I've replaced \n with newlines, and also tested the "expected fail"

This is the second version. Concern was renamed to component, and all
other comments were addressed (I hope). It still uses only two bitmaps
for the component placement, but now they are called needs_components
and has_components, which hopefully is easier to follow. The "can this

This implements the hooks for separate shrink-wrapping for rs6000.

This is the main substance of this patch series.
Instead of doing all of the prologue and epilogue in one spot, it often
is better to do components of it at different places, so that they are
executed less frequently.
What exactly is a component is completely up to the target; this code
treats it
Unfortunately even after the previous patch there are still a few cases
where regrename creates invalid code when used together with separate
