LRA has code to try to prevent cycling, by avoiding reloads that
look too similar to the instruction being reloaded. E.g. if we
have a R<-C move for some constant C, reloading the source with
another R<-C move is unlikely to be a good idea.
However, this safeguard unnecessarily triggered in tests like
the one in the patch. We started with instructions like:
(insn 12 9 13 5 (set (reg:DI 0 x0)
(reg/f:DI 459)) "reg-alloc-1.c":18 47 {*movdi_aarch64}
(expr_list:REG_EQUAL (symbol_ref:DI ("x00") [flags 0xc0] <var_decl 0x7f3c03c1f510 x00>)
(nil)))
where r459 didn't get allocated a register and is equivalent to
constant x00. LRA would then handle it like this:
Changing pseudo 459 in operand 1 of insn 12 on equiv `x00'
1 Non-pseudo reload: reject+=2
1 Non input pseudo reload: reject++
-------> Cycle danger: overall += LRA_MAX_REJECT
alt=0,overall=609,losers=1,rld_nregs=1
[...]
alt=13,overall=9,losers=1,rld_nregs=1
[...]
Choosing alt 13 in insn 12: (0) r (1) w {*movdi_aarch64}
In other words, to avoid loading the constant x00 into another GPR,
LRA decided instead to move it into a floating-point register,
then move that floating-point register into x0:
Creating newreg=630, assigning class FP_REGS to r630
Set class ALL_REGS for r631
12: x0:DI=r630:DI
REG_EQUAL `x00'
Inserting insn reload before:
815: r631:DI=high(`x00')
816: r630:DI=r631:DI+low(`x00')
REG_EQUAL `x00'
That's inefficient and doesn't really help to resolve a cycling
problem, since the r630 destination of 816 needs to be reloaded into
a GPR anyway.
The cycling check already had an exception for source values that are
the result of an elimination. This patch extends it to include the
result of equivalence substitution.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.
This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.
I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.
Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.
I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.
This is v5 of the patch. v4 was applied but caused breakage on big
endian targets. These have been fixed and tested, thanks to access to
the GCC compile farm.
Overview of v4 of the patch: v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.
Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.
Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and
powerpc64-unknown-linux-gnu. Also regtested all three targets by
modifying gfortran-dg.exp to also test with "-g -flto", no new
failures observed.
