[PR81611] turn inc-and-use-of-dead-orig into auto-inc

When the addressing modes available on the machine don't allow offsets

trees and RTL as:

  y <= x + 1

without intervening uses of y into

  (set y x)

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
preserve inline entry blocks for the sake of debug inline

x86-64 is supposed to have asynchronous unwind tables by default, but
there is nothing that reflects the change in the (relative) frame

the .cfi_startproc/.cfi_endproc bracket.

This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
branch via register whenever -mindirect-branch= is used.  Now,
-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:

[Patch AArch64] Turn on frame pointer / partial fix for PR84521

This fixes a GCC-8 regression that we accidentally switched off frame
pointers in the AArch64 backend when changing the defaults in the common
parts of the code. This breaks an ABI decision that was made in GCC at
the dawn of the port with respect to having a frame pointer at all
times.  If we really want to turn this off lets have a discussion around
that separately.

For now turn this back on and I believe this will leave PR84521 latent
again with -fomit-frame-pointer and (hopefully) make the ruby issue go
away. I'm asking Sudi to pick that up.

Bootstrapped and regression tested on AArch64-none-linux-gnu but I see
one regression in gcc.c-torture/execute/960419-2.c which needs to be
looked at next (PR84528, thanks Kyrill).

6 years agoi386: Add __x86_indirect_thunk_nt_reg for -fcf-protection -mcet

i386: Add __x86_indirect_thunk_nt_reg for -fcf-protection -mcet

nocf_check attribute can be used with -fcf-protection -mcet to disable
control-flow check by adding NOTRACK prefix before indirect branch.
When -mindirect-branch=thunk-extern -mindirect-branch-register is added,
indirect branch via register, "notrack call/jmp reg", is converted to

    call/jmp __x86_indirect_thunk_nt_reg

When running on machines with CET enabled, __x86_indirect_thunk_nt_reg
can be updated to

    notrack jmp reg

at run-time to restore NOTRACK prefix in the original indirect branch.

Since we don't support -mindirect-branch=thunk-extern, CET and MPX at
the same time, -mindirect-branch=thunk-extern is disallowed with
-fcf-protection=branch and -fcheck-pointer-bounds.

Tested on i686 and x86-64.

6 years ago[ARM] Multilib mapping for Armv8-R

[ARM] Multilib mapping for Armv8-R

Due to there being no multilib mapping for Armv8-R, default multilib
builts for -march=armv4t with softfloat floating-point arithmetic is
being used. This patch maps it instead to the existing Armv7 multilibs.
Note that mapping for single-precision Armv8-R has been left out due to
there being no Arm implementation of that architecture variant.
