Mark PUSHFS64/PUSHGS64/POPFS64/POPGS64 as In64BitMode and remove the hack from the disassembler table builder.

llvm-svn: 198327

llvm-svn: 198325

Mark all x86 Int_ and _Int patterns as isCodeGenOnly so the disassembler table builder doesn't need to string match them to exclude them.

When building Clang separately from LLVM with CMake, one should set
the path of llvm-config via the cache variable LLVM_CONFIG.

This patch makes it possible to select the ABI with -mattr. It will be used to
forward clang's -target-abi option to llvm's CodeGen.

When there are cycles in the value graph we have to be careful interpreting
"Value*" identity as "value" equivalence. We interpret the value of a phi node
as the value of its operands.
When we check for value equivalence now we make sure that the "Value*" dominates
all cycles (phis).

%0 = phi [%noaliasval, %addr2]
%l = load %ptr
%addr1 = gep @a, 0, %l
%addr2 = gep @a, 0, (%l + 1)
store %ptr ...

Before this patch we would return NoAlias for (%0, %addr1) which is wrong
because the value of the load is from different iterations of the loop.

Tested on x86_64 -mavx at O3 and O3 -flto with no performance or compile time
regressions.

During the years there have been some attempts at figuring out how to
align byval arguments. A look at the commit log suggests that they
were

* Use the ABI alignment.
* When that was not sufficient for x86-64, I added the 's' specification to
  DataLayout.
* When that was not sufficient Evan added the virtual getByValTypeAlignment.
* When even that was not sufficient, we just got the FE to add the alignment
  to the byval.

This patch is just a simple cleanup that removes my first attempt at fixing the
problem. I also added an AArch64 implementation of getByValTypeAlignment to
make sure this patch is a nop. I also left the 's' parsing for backward
compatibility.

I will send a short email to llvmdev about the change for anyone maintaining
an out of tree target.

Remove modifierType/Base from X86 disassembler tables as they are no longer used. Removes ~11.5K from static tables.

[SparcV9]: Use SRL instead of SLL to clear top 32-bits in ctpop:i32. SLL does not clear top 32 bit, only SRL does.

llvm-svn: 198279

Remove need for MODIFIER_OPCODE in the disassembler tables. AddRegFrms are really more like OrRegFrm so we don't need a difference since we can just mask bits.

Printing rounding control.
Enncoding for EVEX_RC (rounding control).

Second attempt at Removing special form of AddRegFrm used by FP instructions. These instructions can be handled by MRMXr instead.

FIXME: Dragonegg may be updated at non-trivial changes.

Revert r198238 and add FP disassembler tests. It didn't work and I didn't realized we had no FP disassembler test cases.

Done the C++11 way, switching on and using LLVM_STATIC_ASSERT() instead of LLVM_ATTRIBUTE_UNUSED.

Checking the trailing letter of the mnemonic is insufficient.  Be more thorough
in the scanning of the instruction to ensure that we correctly work with the
predicated mnemonics.

Remove EscapeFilter. It's funcionality can be covered by correctly using ExtendedFilter and ExactFilter. No functional change.

llvm-svn: 198226

      r198196: Use a pointer to keep track of the skeleton unit for each normal unit and construct it up front.
      r198199: Reapply r198196 with a fix to zero initialize the skeleton pointer.
      r198202: Fix aranges and split dwarf by ensuring that the symbol and relocation back to the compile unit from the aranges section is to the skeleton unit and not the one in the dwo.

with a fix to use integer 0 for DW_AT_low_pc since the relocation to the text section symbol was causing issues with COFF. Accordingly remove addLocalLabelAddress and machinery since we're not currently using it.

Simplify filter accepts function to just return 'condition' instead of branching to return true/false. No functional change.

They could be reproducible with explicit target.
