Saleem Abdulrasool 5c70de1072 MC: correct DWARF header for PE/COFF assembly input
The header contains an offset to the DWARF line table for the CU.  The offset
must be section relative for COFF and absolute for others.  The non-assembly
code path for the DWARF header generation already has the correct emission for
the headers.  This corrects the assembly input path.

This was identified by BFD objecting to the LLVM generated DWARF information.

Jiangning Liu 1a486da543 [AArch64] Add pass to enable additional comparison optimizations by CSE.
Patched by Sergey Dmitrouk.

This pass tries to make consecutive compares of values use same operands to
allow CSE pass to remove duplicated instructions. For this it analyzes
branches and adjusts comparisons with immediate values by converting:

GE -> GT
GT -> GE
LT -> LE
LE -> LT

and adjusting immediate values appropriately. It basically corrects two
immediate values towards each other to make them equal.

Hans Wennborg d71907dd07 Don't emit prologues or epilogues for naked functions (PR18791, PR20028)
For naked functions with parameters, Clang would still emit stores in the prologue
that would clobber the stack, because LLVM doesn't set up a stack frame. (This
shows up in -O0 compiles, because the stores are optimized away otherwise.)

For example:

  __attribute__((naked)) int f(int x) {
    asm("movl $42, %eax");
    asm("retl");
  }

Would result in:

  _Z1fi:
  movl    12(%esp), %eax
  movl    %eax, (%esp)    <--- Oops.
  movl    $42, %eax
  retl

Nick Kledzik 635f9c7158 [mach-o] Let darwin driver infer arch from .o files if -arch not used.
Mach-O has a "fat" (or "universal") variant where the same contents built for
different architectures are concatenated into one file with a table-of-contents
header at the start.  But this leaves a dilemma for the linker - which
architecture to use.

Normally, the linker command line -arch is used to force which slice of any fat
files are used.  The clang compiler always passes -arch to the linker when
invoking it.  But some Makefiles invoke the linker directly and don’t specify
the -arch option.  For those cases, the linker scans all input files in command
line order and finds the first non-fat object file.  Whatever architecture it
is becomes the architecture for the link.

Reid Kleckner 9b3e3dfc54 MS inline asm: Allow __asm blocks to set a return value
If control falls off the end of a function after an __asm block, MSVC
assumes that the inline assembly filled the EAX and possibly EDX
registers with an appropriate return value. This functionality is used
in inline functions returning 64-bit integers in system headers, so we
need some amount of compatibility.

This is implemented in Clang by adding extra output constraints to every
inline asm block, and storing the resulting output registers into the
return value slot. If we see an asm block somewhere in the function
body, we emit a normal epilogue instead of marking the end of the
function with a return type unreachable.

Normal returns in functions not using this functionality will overwrite
the return value slot, and in most cases LLVM should be able to
eliminate the dead stores.

Fixes PR17201.
