Subject: [nvptx] Update help text for m64
X-Git-Tag: basepoints/gcc-13~421
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1625e893cca658a8df3dea50189c932a7025e223;p=thirdparty%2Fgcc.git

[nvptx] Update help text for m64

In the docs we have for m64:
...
Ignored, but preserved for backward compatibility.  Only 64-bit ABI is
supported.
...

But with --target-help, we have instead:
...
$ gcc --target-help
  ...
  -m64    Generate code for a 64-bit ABI.
...
which could be interpreted as meaning that generating code for a 32-bit ABI is
still possible.

Fix this by instead emitting the same text as in the docs:
...
  -m64    Ignored, but preserved for backward compatibility.  Only 64-bit
          ABI is supported.
...

Tested on nvptx.

	* config/nvptx/nvptx.opt (m64): Update help text to reflect that it
	is ignored.
