6 years ago[PR c++/80290] recycle tinst garbage sooner
Alexandre Oliva [Wed, 18 Apr 2018 05:17:26 +0000 (05:17 +0000)]
[PR c++/80290] recycle tinst garbage sooner

tinst_level objects are created during template instantiation, and
they're most often quite short-lived, but since there's no intervening
garbage collection, they accumulate throughout the pass while most by
far could be recycled after a short while.  The original testcase in
PR80290, for example, creates almost 55 million tinst_level objects,
all but 10 thousand of them without intervening GC, but we don't need
more than 284 of them live at a time.

Furthermore, in many cases, TREE_LIST objects are created to stand for
the decl in tinst_level.  In most cases, those can be recycled as soon
as the tinst_level object is recycled; in some relatively common
cases, they are modified and reused in up to 3 tinst_level objects.
In the same testcase, TREE_LISTs are used in all but 3 thousand of the
tinst_level objects, and we don't need more than 89 tinst_level
objects with TREE_LISTs live at a time.  Furthermore, all but 2
thousand of those are created without intervening GC.

This patch arranges for tinst_level objects to be refcounted (I've
seen as many as 20 live references to a single tinst_level object in
my testing), and for pending_template, tinst_level and TREE_LIST
objects that can be recycled to be added to freelists; that's much
faster than ggc_free()ing them and reallocating them shortly
thereafter.  In fact, the introduction of such freelists is what makes
this entire patch lighter-weight, when it comes to memory use, and
faster.  With refcounting alone, the total memory footprint was still
about the same, and we spent more time.

In order to further reduce memory use, I've arranged for us to create
TREE_LISTs lazily, only at points that really need them (when printing
error messages).  This grows tinst_level by an additional pointer, but
since a TREE_LIST holds a lot more than an extra pointer, and
tinst_levels with TREE_LISTs used to be allocated tens of thousands of
times more often than plain decl ones, we still save memory overall.

I was still not quite happy about growing memory use in cases that
used template classes but not template overload resolution, so I
changed the type of the errors field to unsigned short, from int.
With that change, in_system_header_p and refcount move into the same
word or half-word that used to hold errors, releasing a full word,
bringing tinst_level back to its original size, now without any
padding.

The errors field is only used to test whether we've had any errors
since the expansion of some template, to skip the expansion of further
templates.  If we get 2^16 errors or more, it is probably reasonable
to refrain from expanding further templates, even if we would expand
them before this change.

With these changes, compile time for the original testcase at -O0,
with default checking enabled, is cut down by some 3.7%, total GCable
memory allocation is cut down by almost 20%, and total memory use (as
reported by GNU time as maxresident) is cut down by slightly over 15%.

6 years ago[PR c++/85039] no type definitions in builtin offsetof
Alexandre Oliva [Mon, 16 Apr 2018 21:35:34 +0000 (21:35 +0000)]
[PR c++/85039] no type definitions in builtin offsetof

Types defined within a __builtin_offsetof argument don't always get
properly recorded as members of their context types, so if they're
anonymous, we may fail to assign them an anon type index for mangling
and ICE.

We shouldn't allow types to be introduced in __builtin_offsetof, I
think, and Jason says the std committee agrees, so I've arranged for
us to reject them.

Even then, we still parse the definitions and attempt to assign
mangled names to its member functions, so the ICE remains.  Since
we've already reported an error, we might as well complete the name
assignment with an arbitrary index, thus avoiding the ICE.

We used to have a test that expected to be able to define types in
__builtin_offsetof; this patch removes that specific test.

us to be able to generate code for p8 and up with some crucial

rs6000: Fix _mm_slli_epi{32,64} for shift values 16 through 31 and negative (PR84302)

The powerpc versions of _mm_slli_epi32 and __mm_slli_epi64 in emmintrin.h
do not properly handle shift values between 16 and 31, inclusive.
These are setting up the shift with vec_splat_s32, which only accepts
*5 bit signed* shift values, or a range of -16 to 15.  Values above 15
produce an error:

  error: argument 1 must be a 5-bit signed literal

Fix is to effectively reduce the range for which vec_splat_s32 is used
to < 32 and use vec_splats otherwise.

Also, __mm_slli_epi{16,32,64}, when given a negative shift value,
should always return a vector of {0}.
