5 years ago[Ada] Eliminate redundant range checks on conversions
Eric Botcazou [Mon, 12 Aug 2019 08:59:28 +0000 (08:59 +0000)]
[Ada] Eliminate redundant range checks on conversions

This gets rid of redundant range checks generated in 5 out of the 9
cases of scalar conversions, i.e. (integer, fixed-point, floating-point)
converted to (integer, fixed-point, floating-point).

The problem is that the Real_Range_Check routine rewrites the conversion
node into a conversion to the base type so, when its parent node is
analyzed, a new conversion to the subtype may be introduced, depending
on the context, giving rise to a second range check against the subtype
bounds.

This change makes Real_Range_Check rewrite the expression of the
conversion node instead of the node, so that the type of the node is
preserved and no new conversion is introduced.  As a matter of fact,
this is exactly what happens in the float-to-float case which goes to
the Generate_Range_Check circuit instead and does not suffer from the
duplication of range checks.

For the following procedure, the compiler must now generate exactly one
range check per nested function:

procedure P is

  type I1 is new Integer range -100 .. 100;

  type I2 is new Integer range -200 .. 200;

  type D1 is delta 0.5 range -100.0 .. 100.0;

  type D2 is delta 0.5 range -200.0 .. 200.0;

  type F1 is new Long_Float range -100.0 .. 100.0;

  type F2 is new Long_Float range -200.0 .. 200.0;

  function Conv (A : I2) return I1 is
  begin
    return I1 (A);
  end;

  function Conv (A : D2) return I1 is
  begin
    return I1 (A);
  end;

    return I1 (A);

    return D1 (A);
  end;

Reject tail calls that read from an escaped RESULT_DECL (PR90313)

In this PR we have two return paths from a function "map".  The common
code sets <result> to the value returned by one path, while the other
path does:

   <retval> = map (&<retval>, ...);

We'd correctly reject the same thing for variables:

5 years agoskip Cholesky decomposition in is>>n_mv_dist
Alexandre Oliva [Fri, 9 Aug 2019 09:20:58 +0000 (09:20 +0000)]
skip Cholesky decomposition in is>>n_mv_dist

normal_mv_distribution maintains the variance-covariance matrix param
in Cholesky-decomposed form.  Existing param_type constructors, when
taking a full or lower-triangle varcov matrix, perform Cholesky
decomposition to convert it to the internal representation.  This
internal representation is visible both in the varcov() result, and in
the streamed-out representation of a normal_mv_distribution object.

The problem is that when that representation is streamed back in, the
read-back decomposed varcov matrix is used as a lower-triangle
non-decomposed varcov matrix, and it undergoes Cholesky decomposition
again.  So, each cycle of stream-out/stream-in changes the varcov
matrix to its "square root", instead of restoring the original
params.

This patch includes Corentin's changes that introduce verification in
testsuite/ext/random/normal_mv_distribution/operators/serialize.cc and
other similar tests that the object read back in compares equal to the
written-out object: the modified tests pass only if (u == v).

This patch also fixes the error exposed by his change, introducing an
alternate private constructor for param_type, used only by operator>>.

[C] Fix bogus nested enum error message

For:

    enum a { A };
    enum a { B };

we emit a bogus error about nested definitions before the real error:

foo.c:2:6: error: nested redefinition of ‘enum a’
    2 | enum a { B };
      |      ^
foo.c:2:6: error: redeclaration of ‘enum a’
foo.c:1:6: note: originally defined here
    1 | enum a { A };
      |      ^

This is because we weren't clearing C_TYPE_BEING_DEFINED once the
definition was over.

I think it's OK to clear C_TYPE_BEING_DEFINED even for a definition
that actually is nested (and so whose outer definition is still open),
since we'll already have given an error by then.  It means that second
and subsequent attempts to define a nested enum will usually get the
redeclaration error instead of the nested error, but that seems just
as accurate (nested_first and nested_second in the test).  The only
exception is if the first nested enum was also invalid by being empty,
but then the enum as a whole has already produced two errors
(nested_empty in the test).

[AArch64] Merge SVE FP unary patterns

This patch merges the SVE FP rounding patterns with the other SVE
FP unary patterns.

At the moment, we only generate unary FP operations for full vectors,
so we can use (sqrt:VNx4SF ...) etc. in the rtl pattern.  With the ACLE,
it's also possible to generate predicated operations on partial vectors
without specifying a value for inactive lanes.  (sqrt:VNx4SF ...) would
then have different faulting behaviour from the instruction that the
pattern generates.

This patch therefore uses unspecs to represent the operations instead.
Later patches make this change for other patterns.

aarch64-sve.md was getting a bit jumbled, with related operations
separated by unrelated operations.  Also, many SVE instructions need

This patch therefore tries to use an explicit grouping scheme.
Banner comments are usually frowned on, but md files have been
a traditional exception (e.g. when using Mike's template for
new targets).

The patch also lists the instructions implemented by each section,
so that it's possible to search the file by instruction mnemonic.

I wouldn't be surprised if I end up having to rip out the contents
section, but I found it useful for the month or so that that I've
