7 years ago[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.
Iain Sandoe [Sun, 27 Nov 2016 15:07:22 +0000 (15:07 +0000)]
[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.

A/ Newer versions of ld64 check the min_version command, and newer versions of
   the system assembler inserts this in response to "-mmacosx-version-min=" on
   the assembler line. Unless one makes sensible versions, some object is bound
   to conflict.

B/ Additionally, there's a difference in behaviour between "as" and "ld" when
   presented with xx.yy.zz (ld truncates to xx.yy, as doesn't); net result is
   that one needs to pass a truncated version to "as".

So (if the assembler supports minversion commands)
(a) provide a truncated minversion (as asm_macosx_version_min, which is a
    driver-only var).
(b) pass this to "as"
(c) Update tests to determine 'HAVE_AS_MMACOSX_VERSION_MIN_OPTION'
    (Rainer's patch)
(d) For some reason the testcases are "run" (it's not obvious they need to be,
    they are checking compile-time issues)
  - anyway, to preserve the status quo, I've left them as exec.  However, the
    minimum version that can be code-gened for is target-dependent (there are no
    released x86 versions before 10.4, for example).  To avoid conflicts where
    the "as" is assuming some minimum, I've set the testversion to 10.5 (which
    is supported by all the archs we have)
(e) We need to ensure that libgcc and crts are generated with a sufficiently
    old minversion not to conflict.

Iain Sandoe [Sun, 27 Nov 2016 14:50:58 +0000 (14:50 +0000)]
[Darwin] Fix PR57438 by avoiding empty function bodies and trailing labels.

A.
Empty function bodies causes two problems for Darwin's linker (i) zero-length
FDEs and (ii) coincident label addresses that might point to items of
differing weakness.

B.
Trailing local labels can be problematic when they end a function because
similarly they might apparently point to a following weak function, leading
to the linker concluding that there's a pointer-diff to a weak symbol
(which is not allowed).

Both conditions arise from __builtin_unreachable() lowering to a barrier.

The solution for both is to emit some finite amount of code; in the case of A
a trap is emitted, in the case of B a nop.

[Darwin, config] Arrange for ld64 to be detected as Darwin's linker.

 A ld64-compatible linker is currently required and assumed by Darwin.

 see if it is ld64.

 The ld64 version is determined for the chosen ld and this is exported for
 use in setting a default value for -mtarget-linker (needed for run-time
 code-gen changes to section choices).
 The support for -rdynamic is converted to be detected at config time, or

[Darwin, ld64] Make PIC indirections and constant labels linker-visible.

Indirections:

  If we have a situation like:

global_weak_symbol:
  ....
Lnon_weak_local:
  ....

  ld64 will be unable to split this into two atoms (because the "L" makes
  the second symbol 'invisible').  This means that legitimate direct accesses
  to the second symbol will appear to be non-allowed direct accesses to an
  atom of type weak, global which are not allowed.

  To avoid this, we make the indirections have a leading 'l' (lower-case L)
  which has a special meaning: linker can see this and use it to determine
  atoms, but it is not placed into the final symbol table.

  The implementation here is somewhat heavy-handed in that it will also mark
  indirections to the __IMPORT,__pointers section the same way which is
  really unnecessary, since ld64 _can_ split those into atoms as they are
  fixed size.  FIXME: determine if this is a penalty worth extra code to
  fix.

Similarly, with:

  .const
weak_global_constant:
  ....

LCxx:
  ...

 ld64 can't split the second, causing a warning when it's directly
accessed.

Richard Sandiford [Fri, 25 Nov 2016 08:23:08 +0000 (08:23 +0000)]
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.

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])

     (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.
