[LRA] Reload of slow mems
pr71680.c -m64 -O1 -mlra, ira output showing two problem insns.

(expr_list:REG_DEAD (reg:SI 159 [ a ])
(nil)))
Insn 26 requires that reg 159 be of class FLOAT_REGS.
first lra action:
deleting insn with uid = 7.
Changing pseudo 159 in operand 1 of insn 26 on equiv [r158:DI]
Creating newreg=164, assigning class ALL_REGS to subreg reg r164
26: r162:DI=unspec[fix(r164:SI#0)] 7
REG_DEAD r159:SI
Inserting subreg reload before:
30: r164:SI=[r158:DI]
[snip]
Change to class FLOAT_REGS for r164
Well, that didn't do much. lra tried the equiv mem, found that didn't
work, and had to reload. Effectively getting back to the two original
insns but r159 replaced with r164. simplify_operand_subreg did not do
anything in this case because SLOW_UNALIGNED_ACCESS was true (wrongly
for power8, but that's beside the point). So now we have, using
abbreviated rtl notation:
r164:SI=[r158:DI]
r162:DI=unspec[fix(r164:SI)]
The problem here is that the first insn isn't valid, due to the rs6000
backend not supporting SImode in fprs, and r164 must be an fpr to make
the second insn valid.
next lra action:
Creating newreg=165 from oldreg=164, assigning class GENERAL_REGS to r165
30: r165:SI=[r158:DI]
Inserting insn reload after:
31: r164:SI=r165:SI
so now we have
r165:SI=[r158:DI]
r164:SI=r165:SI
r162:DI=unspec[fix(r164:SI)]
This ought to be good on power8, except for one little thing.
r165 is GENERAL_REGS so the first insn is good, a gpr load from mem.
r164 is FLOAT_REGS, making the last insn good, a fctiwz.
The second insn ought to be a sldi, mtvsrd, xscvspdpn combination, but
that is only supported for SFmode. So lra continue on reloading the
second insn, but in vain because it never tries anything other than
SImode and as noted above, SImode is not valid in fprs.
What this patch does is arrange to emit the two reloads needed for the
SLOW_UNALIGNED_ACCESS case at once, moving the subreg to the second
insn in order to switch modes, producing:
r164:SI=[r158:DI]
r165:SF=r164:SI#0
r162:DI=unspec[fix(r165:SF)]
I've also tidied a couple of other things:
1) "old" is unnecessary as it duplicated "operand".
2) Rejecting mem subregs due to SLOW_UNALIGNED_ACCESS only makes sense
if the original mode was not slow.

runtime: treat zero-sized result value as void
Change the FFI interface to treat a call to a function that returns a
zero-sized result as a call to a function that returns void.
This is part of the fix for https://gcc.gnu.org/PR72814. On 32-bit
SPARC systems, a call to a function that returns a non-zero-sized struct
is followed by an unimp instruction that describes the size of the
struct. The function returns to the address after the unimp
instruction. The libffi library can not represent a zero-sized struct,
so we wind up treating it as a 1-byte struct. Thus in that case libffi
calls the function with an unimp instruction, but the function does not
adjust the return address. The result is that the program attempts to
execute the unimp instruction, causing a crash.
This is part of a change that fixes the crash by treating all functions
that return zero bytes as functions that return void.
Reviewed-on: https://go-review.googlesource.com/25585
* go-gcc.cc (Gcc_backend::function_type): If the return type is
zero bytes, treat the function as returning void.

After fixing the constraint problem, we hit an "insn does not satisfy

from mem which has an invalid offset:
(insn 631 630 1122 12 (set (reg:SF 108 31 [orig:260 pretmp_44 ] [260])

Here are the reload costs for the various alternatives of
movsf_hardfloat:
"=!r, !r, m, f, ww, ww, !r, f, wb, m, wY, wu, Z,?wn, ?r,*c*l, !r, *h"

Notice that the cost for a vector<-vector move (ww,ww) is the same as
the cost for a vector<-mem move (wb,wY or wu,Z). Since the
vector<-vector move comes first, it is chosen and the mem part of the
insn reloaded. That just gives another copy of insn 631.

[RS6000] PR72802 part 1, fix constraints for lxssp/stxssp
We can't use "o" constraint for lsxxp/stxssp since those insns have a
DS-form offset field, ie. the bottom two bits of the offset must be 0.
So use "wY" instead, but that leads to finding another problem.
mem_operand_gpr is only suitable for gpr loads/stores since it does
not enforce multiple-of-4 offsets when -m32. So "wY" can't use
mem_operand_gpr, and the vsx tests in mem_operand_gpr are bogus.
I've deleted offsettable_mem_14bit_operand because it wasn't used
anywhere but in the wY constraint. Note also that the new wY
constraint doesn't use memory_operand because that is redundant in a

libgo: change build procedure to use build tags
Previously the libgo Makefile explicitly listed the set of files to
compile for each package. For packages that use build tags, this
required a lot of awkward automake conditionals in the Makefile.
This CL changes the build to look at the build tags in the files.
The new shell script libgo/match.sh does the matching. This required
adjusting a lot of build tags, and removing some files that are never
used. I verified that the exact same sets of files are compiled on
amd64 GNU/Linux. I also tested the build on i386 Solaris.
Writing match.sh revealed some bugs in the build tag handling that
already exists, in a slightly different form, in the gotest shell
script. This CL fixes those problems as well.
The old code used automake conditionals to handle systems that were
missing strerror_r and wait4. Rather than deal with those in Go, those
functions are now implemented in runtime/go-nosys.c when necessary, so
the Go code can simply assume that they exist.
The os testsuite looked for dir_unix.go, which was never built for gccgo
and has now been removed. I changed the testsuite to look for dir.go
instead.
