Any difference between `qcc -Vgcc_ntoaarch64le` and `aarch64-unknown-nto-qnx7.0.0-gcc` when compiling?

Question

Any difference between qcc -Vgcc_ntoaarch64le and aarch64-unknown-nto-qnx7.0.0-gcc when compiling? Are they equivalent?

As per the document, which says that:

For example, this command:

qcc -Vgcc, lists all targets in all versions of gcc. See the Examples section below for more examples.

The targets include:

gcc_ntoaarch64le

gcc_ntoaarch64le_cxx

gcc_ntoaarch64le_gpp

gcc_ntoarmv7le

gcc_ntoarmv7le_cxx

gcc_ntoarmv7le_gpp

gcc_ntox86 (default)

gcc_ntox86_cxx

gcc_ntox86_gpp

gcc_ntox86_64

gcc_ntox86_64_cxx

gcc_ntox86_64_gpp

But I can't find any information about aarch64-unknown-nto-qnx7.0.0-gcc.

Answer 1

-Vgcc_ntoaarch64le is just to configure the compiler.

Open the file gcc_ntoaarch64le.conf. In the host part, you can see qcc actually call aarch64-unknown-nto-qnx7.0.0-gccxxx.
