[Dwarf-Discuss] Do any of the Intel compilers still generate DW_OP_INTEL_bit_piece=0xe8?

[John DelSignore via Dwarf-Discuss]

Hi,

I'm hoping someone from Intel sees this message and can definitively answer the 
following question: Do any of the Intel compilers still generate 
DW_OP_INTEL_bit_piece=0xe8? If not, do you know the last version of the 
compiler that did?

Back in 2007, I added support for the Intel Bi-Endian compiler to TotalView. 
The Intel 9.0.022 compiler generated DW_OP_INTEL_bit_piece when compiling in 
bi-endian mode. In 2009, John Bishop posted the following message: 
.
 So, it appears as if the answer is "no", and it should be safe to assume that 
DW_OP_INTEL_bit_piece is no longer generated by any Intel compiler.

The reason I ask is that the "AMD GPU DWARF extensions for heterogeneous 
debugging" defines DW_OP_LLVM_aspace_bregx=0xe8, which conflicts with 
DW_OP_INTEL_bit_piece.

So, is it safe to remove DW_OP_INTEL_bit_piece and assume that all recent 
(within the last 10 years) Intel compilers now use DW_OP_bit_piece? Or do I 
need to interpret opcode 0xe8 as DW_OP_INTEL_bit_piece when the compilation 
unit's producer smells like an old-ish Intel compiler?

Thanks, John D.

I am still at Intel; I'll ask the debug-info guys and reply later.
