   Summary: Program_Error exp_util.adb:4352 explicit raise related

- a protected type declaration with Lock_Free aspect set to True
- subtyping that protected type
- declaring a record field of this subtype

It should understand FMA indeed, A*B + p[0] + C*D + p[1] + E*F + p[2] can
become(((p[0] + p[1] + p[2]) + A*B) + C*D) + E*F. 

Also we're missing a reassociation depth parameter. You need to be able to
specify how long a chain needs to be before it is worth splitting - the example
shows a chain of 5 FMAs is not worth splitting since FMA latency on modern
cores is low, but if these were integer operations (not MADD) then the chain
should be split.

I have a patch to do this, but 
(a) I’ve just seen that you said "append", 
(b) if the added switches include -gnat, you’d need to make sure
you only ran "make check-acats" - -g looks like a debug 
option
(c) RUNTESTFLAGS doesn’t get transmitted to the sub-makes in the
check-acats target if you 'make -j'

Bug ID: 84319
   Summary: [8 regression] Location views break bootstrap with
Solaris/SPARC as
   Product: gcc
   Version: 8.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: debug
  Assignee: unassigned at gcc dot gnu.org

CC: aoliva at gcc dot gnu.org
  Target Milestone: ---
  Host: sparc-sun-solaris2.*
Target: sparc-sun-solaris2.*
 Build: sparc-sun-solaris2.*

The location views patch breaks bootstrap on Solaris/SPARC with the native as.

The picture is a bit complicated because some builds fail earlier due to the
SEGV
described in PR debug/84317.  Here's the overview:

as/ld   gas/ld  gas/gld as/ld-64 gas/ld-64

  s10   segvsegvsegvdiff ok
  s11   diffsegvsegvdiff ok
  s11.4 ok  ok  ok  diff ???

(s11 is Solaris 11.3, s11.4 is Solaris 11.4 Beta)

The `diff' cases fail like this (e.g. compiling the 64-bit
libstdc++-v3/src/c++11/iostream-inst.cc) with -fPIC:

/usr/ccs/bin/as: "iostream-inst.s", line 26808: error: can't compute difference

The last line is from dwarf2out.c (output_one_line_info_table) using
dw2_asm_output_delta, which has a fat comment about targets that cannot compute
the difference between symbols in different sections.

Adding -gno-variable-location-views to the compilation makes it succeed.

Hence it looks like this is a duplicate of PR c++/84263 (but hard to be sure
without properly reducing it).

Nathan: does this look like a duplicate to you?  Any ideas on how to reduce the
reproducer?  (the ~1hr time to hit the bug when forcing GC is making this
awkward).

Alan: are you able to test Nathan's bug to see if it fixes the issue for you?

Thanks.

Besides inline asm barriers another option is volatile {float,double} vars in
certain spots (to ensure rounding to {float,double} where required).  And
again, you don't need to do anything if FLT_EVAL_METHOD is 0, or for double
computations also if FLT_EVAL_METHOD is 1.

Thanks for the thorough analysis. We'll discuss in our team how to cope with
it.
