Improve alloca alignment

This patch improves alloca alignment.  Currently alloca reserves
too much space as it aligns twice, and generates unnecessary stack
alignment code.

When the requested alignment is lower than the stack alignment, no
extra alignment is needed.  If the requested alignment is higher,
we need to increase the size by the difference of the requested
alignment and the stack alignment.  As a result, the alloca alignment
is exactly as expected:

alloca (16):
sub sp, sp, #16
mov x1, sp

alloca (x):
add x0, x0, 15
and x0, x0, -16
sub sp, sp, x0
mov x0, sp

__builtin_alloca_with_align (x, 512):
add x0, x0, 63
and x0, x0, -16
sub sp, sp, x0
add x0, sp, 63
and x0, x0, -64

6 years agoTurn HARD_REGNO_CALL_PART_CLOBBERED into a target hook
Richard Sandiford [Mon, 4 Sep 2017 10:49:21 +0000 (10:49 +0000)]
Turn HARD_REGNO_CALL_PART_CLOBBERED into a target hook

The SVE patches change the size of a machine_mode from a compile-time
constant to a runtime invariant.  However, target-specific code can
continue to treat the modes as constant-sized if the target only has
constant-sized modes.

The main snag with this approach is that target-independent code still
uses macros from the target .h file.  This patch is one of several that
converts a target macro to a hook.

PR82045: Avoid passing machine modes through "..."

PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..."  to emit_library_call(_value), which then
read them back as ints instead.

The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases.  This
bulks out rtl.h a bit, but it does make things a bit more typesafe.

Segher Boessenkool [Fri, 1 Sep 2017 16:54:53 +0000 (18:54 +0200)]
combine: Fix for PR82024

With the testcase in the PR, with all the command line options mentioned
there, a (comparison) instruction becomes dead in fwprop1 but is not
deleted until all the way in rtl_dce.

Before combine this insn look like:

20: flags:CC=cmp(r106:DI,0xffffffffffffffff)
      REG_DEAD r106:DI
      REG_UNUSED flags:CC
      REG_EQUAL cmp(0,0xffffffffffffffff)

(note the only output is unused).

Combining some earlier insns gives

13: r106:DI=0
14: r105:DI=r101:DI+r103:DI

14+13+20 then gives

(parallel [
        (set (reg:CC 17 flags)
            (compare:CC (const_int 0 [0])
                (const_int -1 [0xffffffffffffffff])))
        (set (reg:DI 105)
            (plus:DI (reg/v:DI 101 [ e ])
                (reg:DI 103)))
    ])

which doesn't match; but the set of flags is dead, so combine makes the
set of r105 the whole new instruction, which it then places at i3.  But
that is wrong, because r105 is used after i2 but before i3!  We forget
to check for that in this case.

This patch fixes it.

6 years agoFix excess precision handling of compound assignments (PR c/82071).
Joseph Myers [Fri, 1 Sep 2017 16:29:49 +0000 (17:29 +0100)]
Fix excess precision handling of compound assignments (PR c/82071).

PR c/82071 reports how compound assignment operators such as += handle
excess precision inconsistently with the same operation done with a
plain assignment and binary operator.

There were (at least) two problems with how compound assignments
handled excess precision.  The EXCESS_PRECISION_EXPR for an argument
with excess precision was removed too early, resulting in
build_binary_op being called with an rhs operand whose type reflected
the evaluation format, so not having sufficient information to achieve
the intended semantics in all cases, and then the code called
c_fully_fold on the results of build_binary_op without allowing for
the possibility of an EXCESS_PRECISION_EXPR as the result, so leading
to double rounding of the result (first to its semantic type, then to
the type of the LHS of the assignment) instead of the intended single
rounding.

This patch fixes those problems by keeping EXCESS_PRECISION_EXPRs
further through build_modify_expr (and build_atomic_assign which it
calls) and only removing them locally where appropriate.

Note that while this patch should achieve *consistency*, that's
consistency with the understanding of C99 semantics that I originally
intended to implement.  For the particular case in the testcase, C11
semantics (from N1531) differ from that understanding of C99
semantics, in that an implicit conversion of an integer to floating
point can have excess precision.  I intend to implement those C11
semantics separately (conditional on flag_isoc11) (which will also
mean that building conditional expressions can produce a result with
excess precision even when the arguments lack excess precision, where
previously it could not), and not to close the bug until that is also
done.

Tested for x86_64-pc-linux-gnu.

[AArch64] Rename cmp_result iterator

The comparison results provided by the V_cmp_result/v_cmp_result
attribute were simply the corresponding integer vector.  We'd also
like to have easy access to the integer vector for SVE, but using
"cmp_result" would be confusing because SVE comparisons return
predicates instead of vectors.  This patch therefore renames the
attributes to the more general V_INT_EQUIV/v_int_equiv instead.

As to the capitalisation: there are already many iterators that use
all lowercase vs. all uppercase names to distinguish all lowercase
vs. all uppercase expansions (e.g. fcvt_target and FCVT_TARGET).
It's also the convention used for the built-in mode/MODE/code/CODE/etc.
attributes.  IMO those names are easier to read at a glance, rather than
relying on a single letter's difference.

[AArch64] Remove use of wider vector modes

The AArch64 port defined x2, x3 and x4 vector modes that were only used
in the rtl for the AdvSIMD LD{2,3,4} patterns.  It seems unlikely that
this rtl would have led to any valid simplifications, since the values
involved were unspecs that had a different number of operands from the
non-dreg versions.  (The dreg UNSPEC_LD2 had a single operand, while
the qreg one had two operands.)

As it happened, the patterns led to invalid simplifications on big-
endian targets due to a mix-up in the operand order, see Tamar's fix
in r240271.

This patch therefore replaces the rtl patterns with dedicated unspecs.
This allows the x2, x3 and x4 modes to be removed, avoiding a clash
with 256-bit and 512-bit SVE.

Add a partial_subreg_p predicate

This patch adds a partial_subreg_p predicate to go alongside
paradoxical_subreg_p.

Like the paradoxical_subreg_p patch, this one replaces some tests that
were based on GET_MODE_SIZE rather than GET_MODE_PRECISION.  In each
case the change should be a no-op or an improvement.

The regcprop.c patch prevents some replacements of the 82-bit RFmode
with the 80-bit XFmode on ia64.  I don't understand the target details
here particularly well, but from the way the modes are described in
ia64-modes.def, it isn't valid to assume that an XFmode can carry an
RFmode payload.  A comparison of the testsuite assembly output for one
target per CPU showed no other differences.

Some of the places changed here are tracking the widest access mode
found for a register.  The series tries to standardise on:

  if (partial_subreg_p (widest_seen, new_mode))
    widest_seen = new_mode;

rather than:

  if (paradoxical_subreg_p (new_mode, widest_seen))
    widest_seen = new_mode;

Either would have been OK.
