Add MCContext argument to MCAsmBackend::applyFixup for error reporting

A number of backends (AArch64, MIPS, ARM) have been using
MCContext::reportError to report issues such as out-of-range fixup values in
their TgtAsmBackend. This is great, but because MCContext couldn't easily be
threaded through to the adjustFixupValue helper function from its usual
callsite (applyFixup), these backends ended up adding an MCContext* argument
and adding another call to applyFixup to processFixupValue. Adding an
MCContext parameter to applyFixup makes this unnecessary, and even better -
applyFixup can take a reference to MCContext rather than a potentially null
pointer.

7 years ago[X86] Relax assert in broadcast-of-subvector lowering.
Ahmed Bougacha [Wed, 5 Apr 2017 00:14:39 +0000 (00:14 +0000)]
[X86] Relax assert in broadcast-of-subvector lowering.

Before r294774, there was a problem when lowering broadcasts to use
128-bit subvectors.

When we looked through a bitcast to find the broadcast input, we'd keep
using the original type, so you'd end up with things like:
  (v8f32 (broadcast
    (v4f32 (extract_subvector
      (v8i32 V),
      ...))
    ))

r294774 fixed it to always emit subvectors with the scalar type of the
original source.

It also introduced some asserts, to check that we use scalars with
the same size, and vectors with the same number of elements.

The scalar size equality is checked earlier when looking through bitcasts,
and is a useful assert.

However, the number of elements don't have to be identical: we're always
going to extract a 128-bit subvector, and we can have different size
inputs if we looked through a concat_vector to find a 256-bit source.

Relax the overzealous assert.

Replace it with a check of the original source vector being 256 or 512
bits.  If it's 128 bits, we can't extract_subvector from it.

Fixes PR32371.

Summary:
Lift the restrictions that prevented the tree walking introduced in the
previous change and add support for patterns like:
  (G_ADD (G_MUL (G_SEXT $src1), (G_SEXT $src2)), $src3) -> SMADDWrrr $dst, $src1, $src2, $src3
Also adds support for G_SEXT and G_ZEXT to support these cases.

One particular aspect of this that I should draw attention to is that I've
tried to be overly conservative in determining the safety of matches that
involve non-adjacent instructions and multiple basic blocks. This is intended
to be used as a cheap initial check and we may add a more expensive check in
the future. The current rules are:
* Reject if any instruction may load/store (we'd need to check for intervening
  memory operations.
* Reject if any instruction has implicit operands.
* Reject if any instruction has unmodelled side-effects.

x86 interrupt calling convention: re-align stack pointer on 64-bit if an error code was pushed

The x86_64 ABI requires that the stack is 16 byte aligned on function calls. Thus, the 8-byte error code, which is pushed by the CPU for certain exceptions, leads to a misaligned stack. This results in bugs such as Bug 26413, where misaligned movaps instructions are generated.

This commit fixes the misalignment by adjusting the stack pointer in these cases. The adjustment is done at the beginning of the prologue generation by subtracting another 8 bytes from the stack pointer. These additional bytes are popped again in the function epilogue.
