* i386: Avoid stack realignment if possiblehjl/pr81313/masterH.J. Lu2017-08-062-30/+56
| | | | | | | | | | | | | | | | | | | | Since DRAP isn't used with -maccumulate-outgoing-args, pr59501-4a.c was xfailed due to stack frame access via frame pointer instead of DARP. This patch finds the maximum stack alignment from the stack frame access instructions and avoids stack realignment if stack alignment needed is less than or equal to incoming stack boundary. gcc/ PR target/59501 * config/i386/i386.c (ix86_finalize_stack_realign_flags): Don't realign stack if stack alignment needed is less than incoming stack boundary. gcc/testsuite/ PR target/59501 * gcc.target/i386/pr59501-4a.c: Remove xfail.

* Pool alignment information for common basesrsandifo2017-08-049-14/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a follow-on to the fix for PR81136. The testcase for that PR shows that we can (correctly) calculate different base alignments for two data_references but still tell that their misalignments wrt the vector size are equal. This is because we calculate the base alignments for each dr individually, without looking at the other drs, and in general the alignment we calculate is only guaranteed if the dr's DR_REF actually occurs. This is working as designed, but it does expose a missed opportunity. We know that if a vectorised loop is reached, all statements in that loop execute at least once, so it should be safe to pool the alignment information for all the statements we're vectorising. The only catch is that DR_REFs for masked loads and stores only occur if the mask value is nonzero. For example, in: struct s __attribute__((aligned(32))) { int misaligner; int array[N]; }; int *ptr; for (int i = 0; i < n; ++i) ptr[i] = c[i] ? ((struct s *) (ptr - 1))->array[i] : 0; we can only guarantee that ptr points to a "struct s" if at least one c[i] is true. This patch adds a DR_IS_CONDITIONAL_IN_STMT flag to record whether the DR_REF is guaranteed to occur every time that the statement executes to completion. It then pools the alignment information for references that aren't conditional in this sense. 2017-08-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR tree-optimization/81136 * tree-vectorizer.h: Include tree-hash-traits.h.

It sets a new flag DDR_COULD_BE_INDEPENDENT_P if the dependence isn't guaranteed to occur. The motivating example is: struct s { int x[8]; }; void f (struct s *a, struct s *b) { for (int i = 0; i < 8; ++i) a->x[i] += b->x[i]; } in which the "a" and "b" accesses are either independent or have a dependence distance of 0 (assuming -fstrict-aliasing). Neither case prevents vectorisation, so we can vectorise without an alias check. I'd originally wanted to do the same thing for arrays as well, e.g.: void f (int a[][8], struct b[][8]) { for (int i = 0; i < 8; ++i) a[0][i] += b[0][i]; } I think this is valid because C11 6.7.6.2/6 says: For two array types to be compatible, both shall have compatible element types, and if both size specifiers are present, and are integer constant expressions, then both size specifiers shall have the same constant value. So if we access an array through an int (*)[8], it must have type X[8] or X[], where X is compatible with int. It doesn't seem possible in either case for "a[0]" and "b[0]" to overlap when "a != b". However, as the comment above "if (same_base_p)" explains, GCC is more forgiving: it supports arbitrary overlap of arrays and allows arrays to be accessed with different dimensionality. There are examples of this in PR50067. The patch therefore only handles references that end in a structure field access. There are two ways of handling these dependences in the vectoriser: use them to limit VF, or check at runtime as before. I've gone for the approach of checking at runtime if we can, to avoid limiting VF unnecessarily, but falling back to a VF cap when runtime checks aren't allowed. The patch tests whether we queued an alias check with a dependence distance of X and then picked a VF <= X, in which case it's safe to drop the alias check. Since vect_prune_runtime_alias_check_list can be called twice with different VF for the same loop, it's no longer safe to clear may_alias_ddrs on exit. Instead we should use comp_alias_ddrs to check whether versioning is necessary. 2017-08-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-data-ref.h (subscript): Add access_fn field.
