Hi, 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. Committed to trunk. Thanks, - Tom [nvptx] Update help text for m64 gcc/ChangeLog: 2022-03-29 Tom de Vries <tdevr...@suse.de> * config/nvptx/nvptx.opt (m64): Update help text to reflect that it is ignored. --- gcc/config/nvptx/nvptx.opt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gcc/config/nvptx/nvptx.opt b/gcc/config/nvptx/nvptx.opt index 58eddeeabf4..55a10572dd1 100644 --- a/gcc/config/nvptx/nvptx.opt +++ b/gcc/config/nvptx/nvptx.opt @@ -25,7 +25,8 @@ m64 Target RejectNegative Mask(ABI64) -Generate code for a 64-bit ABI. +Ignored, but preserved for backward compatibility.
