This patch renames values of dsymutil/llvm-dwarfutil options: --linker apple -> --linker classic --linker llvm -> --linker parallel The purpose to rename options is to avoid using vendor names and to match with library names. It should be safe to rename options at current stage as they are not seemed widely used(we may not preserve backward compatibility).

/* Compile with:
|
|
clang -g -c odr-uniquing.cpp -o odr-uniquing/1.o
|
|
cp odr-uniquing/1.o odr-uniquing/2.o
|
|
The aim of these test is to check that all the 'type types' that
|
|
should be uniqued through the ODR really are.
|
|
|
|
The resulting object file is linked against itself using a fake
|
|
debug map. The end result is:
|
|
- with ODR uniquing: all types (expect for the union for now) in
|
|
the second CU should point back to the types of the first CU.
|
|
- without ODR uniquing: all types are re-emited in the second CU
