Tighten use of HARD_FRAME_POINTER_REGNUM in alias.c (PR 84538)

RTL code needs to be consistent about whether it uses the stack
pointer, the frame pointer or the argument pointer to access a
given part of the frame.  alias.c used this to divide accesses
into three independent areas.

The problem in the PR is that we did this for HARD_FRAME_POINTER_REGNUM
even when the register wasn't being used as a frame pointer.  We can't
do that because the frame pointer is then just any old allocatable
register and could certainly point to info accessed through the
argument pointer or stack pointer.

Alexandre Oliva [Tue, 27 Feb 2018 03:37:10 +0000 (03:37 +0000)]
[IEPM] don't preserve lexical blocks just for debug inline markers

This patch stops preserving scope blocks just because they are inlined
function scopes, when cleaning up unused scope blocks.  This change
was introduced along with IEPM, but it preserved lots of blocks, and
output debug information for them, although no code from the inlined
function remained after optimization.

The additional preserved blocks took up compile-time memory, and
significant disk space and link time, in some cases more than 25%.
This is deemed excessive, compared with the reasonably small benefit
of allowing one to single-step into an inlined function using a
view-capable debugger.

There was another way of marking inlined function scopes as unused,
based on the markers referencing them during stmt scanning, but that
still preserved too much.

So, this patch restores the pre-IEPM logic of preservation of scopes.
Should a scope block referenced by an inline entry marker be found to
be unused in remove_unused_scope_block_p, the marker will be cleaned
up right after that, in clear_unused_block_pointer, so we won't keep
a dangling reference to a dropped block.

* tree-ssa-live.c (remove_unused_scope_block_p): Do not
