8 years agoClean up PURE_SLP_STMT handling
Richard Sandiford [Tue, 24 May 2016 14:05:20 +0000 (14:05 +0000)]
Clean up PURE_SLP_STMT handling

The vectorizable_* routines had many instances of:

        slp_node || PURE_SLP_STMT (stmt_info)

which gives the misleading impression that we can have
!slp_node && PURE_SLP_STMT (stmt_info).  In this context
it's really enough to test slp_node on its own.

There are three cases:

      loop vectorisation only:
        vectorizable_foo called only with !slp_node

      pure SLP:
        vectorizable_foo called only with slp_node

      hybrid SLP:
        (e.g. a vector that's used in SLP statements and also in a reduction)
        - vectorizable_foo called once with slp_node for the SLP uses.
        - vectorizable_foo called once with !slp_node for the non-SLP uses.

Hybrid SLP isn't possible for stores, so I added an explicit assert
for that.

I also made vectorizable_comparison static, to make it obvious that
no other callers outside tree-vect-stmts.c could use it with the
!slp && PURE_SLP_STMT combination.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.

Avoid unnecessary peeling for gaps with LD3

vectorizable_load forces peeling for gaps if the vectorisation factor
is not a multiple of the group size, since in that case we'd normally load
beyond the original scalar accesses but drop the excess elements as part

This patch adds support for the signed and unsigned int versions of the
vec_addec altivec builtins from the Power Architecture 64-Bit ELF V2 ABI
OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are
many of the builtins that are missing and this is part of a series
of patches to add them.

There aren't instructions for the int versions of vec_addec so the
output code is built from other built-ins that do have instructions
which in this case is the following.

vec_addec (va, vb, carryv) == vec_or (vec_addc (va, vb),
vec_addc(vec_add(va, vb),
 vec_and (carryv, 0x1)))

The new test cases are executable tests which verify that the generated
code produces expected values. C macros were used so that the same
test case could be used for both the signed and unsigned versions. An
extra executable test case is also included to ensure that the modified
support for the __int128 versions of vec_addec is not broken. The same
test case could not be used for both int and __int128 because of some
differences in loading and storing the vectors.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?

PR c/71171: Fix uninitialized source_range in c_parser_postfix_expression

A common way for a c_expr to have an uninitialized src_range is in
error-handling, where the "value" field is set to error_mark_node
without touching the src_range, leading to complaints from valgrind.

This patch introduces a new method c_expr::set_error which sets
the value to error_mark_node whilst initializing the src_range to
UNKNOWN_LOCATION.

This fixes the valgrind issue seen in PR c/71171, along with various
other related issues seen when running the testsuite using the
checker patch I posted here:
  https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00887.html
(this checker still doesn't fully work yet, but it seems to be good
for easily detecting these issues without needing Valgrind).
