auto-inc-dec: Set alignment properly

When auto-inc-dec creates a new mem to compute the cost of doing some
transform, it forgets to copy over the alignment of the original mem.
This gives wrong costs, for example, for rs6000 a floating point load

combine: Count auto_inc properly (PR89794)

libphobos: Move rt.sections modules to gcc.sections

These modules depend on a mixture between how the compiler emits
run-time module information, and what functions are exposed by the
platform to inquire about loaded global and thread-local data sections.

As the upstream implementation is written to work only with how the
reference D compiler writes out data, much of what is present does not
apply to the GCC D front-end.  So it has been moved to a non-upstream
location in the source tree, where most of it will be rewritten once
each port has been completed.

The only tested module sections/elf_shared.d has been cleaned up so that
all deprecated declarations have been removed, as well as the brittle
module collision checking, which required bss_sections.c.  All other
ports have been left unchanged apart from a commonizing of attributes.

Andreas Krebbel [Fri, 12 Apr 2019 07:41:51 +0000 (07:41 +0000)]
S/390: Fix a problem with the bswap vector pattern

arch13 introduced instructions to perform vector element-wise byte
swaps on the way from or to memory.  For a byte swap between vector
registers the vector permute instruction is required which needs a
permute pattern to be loaded into a vector register first.

With the current implementation there is a potential problem when the
decision for the reg-reg variant is made very late.  This patch is
supposed to fix that.

With the patch the required permute pattern is generated already in
the expander and attached to the bswap pattern as USE operand.  The
predicate in the insn_and_split pattern accepts it although the
permute constant as such is not a valid constant.  For the reg-reg
variant only the vector register constraint is used for the permute
constant forcing LRA to a) push the constant into literal pool and b)
load the literal pool constant into a vector register.

5 years agod: Add -fbuilding-libphobos-tests option

d: Add -fbuilding-libphobos-tests option

Currently, the druntime and phobos unittests are compiled as a separate
check program, then ran by the libphobos.unittest/unittest.exp script.
As PR d/89255 notes, this process lacks proper multilib handling.

As a first step, a new internal option that instructs the compiler to
put the reference to all unittest functions in another symbol has been
added.  This will allow each module to be compiled separately as a
standalone program using dg-runtest without running into collisions in
the D runtime module registry.

PR libstdc++/90046 fix build failure on epiphany-elf

The epiphany-elf target aligns structs to 8 bytes, which causes the
static_assert(alignof(_Chunk) == 1) to fail.

Instead of requiring _Chunks to be positionable at any alignment, ensure
new buffers are aligned to alignof(_Chunk). Because the buffer size is a
power of two, we know that both the buffer size and sizeof(_Chunk) are
multiples of alignof(_Chunk). So is p is aligned to alignof(_Chunk) then
so is (p + size - sizeof(_Chunk)). So just ensure the new buffer is
aligned to at least alignof(_Chunk), which should already be true
because the caller requests at least alignof(max_align_t).
