PPC32: Fix stack collision between FP and CR save areas.

The changes to CR spill handling missed a case for 32-bit PowerPC.
The code in PPCFrameLowering::processFunctionBeforeFrameFinalized()
checks whether CR spill has occurred using a flag in the function
info.  This flag is only set by storeRegToStackSlot and
loadRegFromStackSlot.  spillCalleeSavedRegisters does not call
storeRegToStackSlot, but instead produces MI directly.  Thus we don't
see the CR is spilled when assigning frame offsets, and the CR spill
ends up colliding with some other location (generally the FP slot).

This patch sets the flag in spillCalleeSavedRegisters for PPC32 so
that the CR spill is properly detected and gets its own slot in the
stack frame.

[SystemZ] Rework handling of constant PC-relative operands

The GNU assembler treats things like:

        brasl   %r14, 100

in the same way as:

        brasl   %r14, .+100

rather than as a branch to absolute address 100.  We implemented this in
LLVM by creating an immediate operand rather than the usual expr operand,
and by handling immediate operands specially in the code emitter.
This was undesirable for (at least) three reasons:

- the specialness of immediate operands was exposed to the backend MC code,
  rather than being limited to the assembler parser.

- in disassembly, an immediate operand really is an absolute address.
  (Note that this means reassembling printed disassembly can't recreate
  the original code.)

- it would interfere with any assembly manipulation that we might
  try in future.  E.g. operations like branch shortening can change
  the relative position of instructions, but any code that updates
  sym+offset addresses wouldn't update an immediate "100" operand
  in the same way as an explicit ".+100" operand.

This patch changes the implementation so that the assembler creates
a "." label for immediate PC-relative operands, so that the operand
to the MCInst is always the absolute address.  The patch also adds
some error checking of the offset.

11 years agoThis is the first of three patches which creates stubs used for
Reed Kotler [Tue, 14 May 2013 02:00:24 +0000 (02:00 +0000)]
This is the first of three patches which creates stubs used for
Mips16/32 floating point interoperability.

When Mips16 code calls external functions that would normally have some
of its parameters or return values passed in floating point registers,
it needs (Mips32) helper functions to do this because while in Mips16 mode
there is no ability to access the floating point registers.

In Pic mode, this is done with a set of predefined functions in libc.
This case is already handled in llvm for Mips16.

In static relocation mode, for efficiency reasons, the compiler generates
stubs that the linker will use if it turns out that the external function
is a Mips32 function. (If it's Mips16, then it does not need the helper
stubs).

These stubs are identically named and the linker knows about these tricks
and will not create multiple copies and will delete them if they are not
needed.

[objc-arc-opts] In the presense of an alloca unconditionally remove RR pairs if and only if we are both KnownSafeBU/KnownSafeTD rather than just either or.

In the presense of a block being initialized, the frontend will emit the
objc_retain on the original pointer and the release on the pointer loaded from
the alloca. The optimizer will through the provenance analysis realize that the
two are related (albiet different), but since we only require KnownSafe in one
direction, will match the inner retain on the original pointer with the guard
release on the original pointer. This is fixed by ensuring that in the presense
of allocas we only unconditionally remove pointers if both our retain and our
release are KnownSafe (i.e. we are KnownSafe in both directions) since we must
deal with the possibility that the frontend will emit what (to the optimizer)
appears to be unbalanced retain/releases.

An example of the miscompile is:

  %A = alloca
  retain(%x)
  retain(%x) <--- Inner Retain
  store %x, %A
  %y = load %A
  ... DO STUFF ...

  release(%x) <--- Guarding Release

  %A = alloca
  retain(%x)
  store %x, %A
  %y = load %A
  ... DO STUFF ...

PPC64: Constant initializers with dynamic relocations go in .data.rel.ro.

This fixes warning messages observed in the oggenc application test in
projects/test-suite.  Special handling is needed for the 64-bit
PowerPC SVR4 ABI when a constant is initialized with a pointer to a
function in a shared library.  Because a function address is
implemented as the address of a function descriptor, the use of copy
relocations can lead to problems with initialization.  GNU ld
therefore replaces copy relocations with dynamic relocations to be
resolved by the dynamic linker.  This means the constant cannot reside
in the read-only data section, but instead belongs in .data.rel.ro,
which is designed for constants containing dynamic relocations.

The implementation creates a class PPC64LinuxTargetObjectFile
inheriting from TargetLoweringObjectFileELF, which behaves like its
parent except to place constants of this sort into .data.rel.ro.

The test case is reduced from the oggenc application.

Reed Kotler [Fri, 10 May 2013 22:25:39 +0000 (22:25 +0000)]
Checkin in of first of several patches to finish implementation of
mips16/mips32 floating point interoperability.

This patch fixes returns from mips16 functions so that if the function
was in fact called by a mips32 hard float routine, then values
that would have been returned in floating point registers are so returned.

Mips16 mode has no floating point instructions so there is no way to
load values into floating point registers.

This is needed when returning float, double, single complex, double complex
in the Mips ABI.

Helper functions in libc for mips16 are available to do this.

For efficiency purposes, these helper functions have a different calling
convention from normal Mips calls.

Registers v0,v1,a0,a1 are used to pass parameters instead of
a0,a1,a2,a3.

This is because v0,v1,a0,a1 are the natural registers used to return
floating point values in soft float. These values can then be moved
to the appropriate floating point registers with no extra cost.

The only register that is modified is ra in this call.

The helper functions make sure that the return values are in the floating
point registers that they would be in if soft float was not in effect
(which it is for mips16, though the soft float is implemented using a mips32
library that uses hard float).

MatchInstructionImpl function weren't being set properly.  Specifically, when
parsing intel syntax, the parser thought it was parsing inline assembly in the

The crash was caused when the emitter tried to emit the instruction, but the
operands weren't set.  When parsing inline assembly we only set the opcode, not
the operands, which is used to lookup the instruction descriptor.
