- Subject: [PATCH, ARM] Clarify doc for .arch/.cpu
Documentation for .arch and .cpu directives currently says that it
accepts the same name as -march/-mcpu command-line options respectively.
However it only accept the architecture/CPU part of those options: it
does not accept specifying an extension which is done via
.arch_extension. This patch clarifies that the extension is not
accepted.
ChangeLog entry is as follows:
*** gas/ChangeLog ***
2018-07-25 Thomas Preud'homme <thomas.preudhomme@linaro.org>
* doc/c-arm.texi (.arch directive): Clarify that name must not include
an extension.
(.cpu directive): Likewise.
Testing: Successfully built the info, PDF and HTML gas documentation.
Is this ok for master?
Best regards,
Thomas
