Tweak LRA handling of shared spill slots

The previous code processed the users of a stack slot in order of
decreasing size and allocated the slot based on the first user.
This seems a bit dangerous, since the ordering is based on the
mode of the biggest reference while the allocation is based also
on the size of the register itself (which I think could be larger).

That scheme doesn't scale well to polynomial sizes, since there's
no guarantee that the order of the sizes is known at compile time.
This patch instead records an upper bound on the size required
by all users of a slot.  It also records the maximum alignment
requirement.

Richard Sandiford [Fri, 25 Nov 2016 08:20:40 +0000 (08:20 +0000)]
Set mode of decimal floats before calling layout_type

Previously decimal floating-point types were created and laid
out as binary floating-point types, then the caller changed
the mode to a decimal mode later.  The problem with that
approach is that not all targets support an equivalent binary
floating-point mode.  When they didn't, we would give the
type BLKmode and lay it out as a zero-sized type.

This probably had no effect in practice.  If a target doesn't
support a binary mode then it's unlikely to support the decimal
equivalent either.  However, with the stricter mode checking
added by later patches, we would assert if a scalar floating-
point type didn't have a scalar floating-point mode.

Joseph Myers [Wed, 23 Nov 2016 23:34:05 +0000 (23:34 +0000)]
Fix e500 offset handling for TImode.

Given my previous fix for a missing insn pattern for e500, building
glibc runs into an assembler error "Error: operand out of range (256
is not between 0 and 248)".  This comes from an insn:

(insn 115 1209 1210 (set (reg:DF 27 27 [orig:294 _129 ] [294])
        (subreg:DF (mem/c:TI (plus:SI (reg/f:SI 1 1)

     (nil))

This patch adjusts the offset handling for TImode - and TDmode and
PTImode in case such subregs can arise for them - to be the same as
for TFmode, so that proper SPE offset checks are made in the
TARGET_E500_DOUBLE case.

This allows the glibc build to complete.  Testing shows 372 FAILs
across the gcc, g++ and libstdc++ testsuites; more cleanup is
certainly needed, but this gets to the point where the toolchain at
least builds so it's possible to compare test results when fixing
bugs.

* config/rs6000/rs6000.c (rs6000_legitimate_offset_address_p): For

../sysdeps/ieee754/ldbl-128ibm/s_modfl.c:91:1: internal compiler error: in extract_insn, at recog.c:2311

This patch adds an insn pattern similar to various patterns already
present to handle extracting such a subreg.  This allows the glibc
build to get further, until it runs into an assembler error for which
I have another patch.

gcc:

combine: Query can_change_dest_mode before changing dest mode

As reported in https://gcc.gnu.org/ml/gcc-patches/2016-11/msg02388.html .

it can make worse code if the result will need reloads.
