Proposed patch to silence the warning if the new attribute is same
Hello,
I propose the attached patch for this. I'm flying blind here and the patch is
not yet tested.
The idea is to search whether the attribute to be applied is already set and if
this is the case, to not emit a warning, and otherwise to rephrase the warning
pointing out that a different attribute was specified.
The code was inspired by the lines starting from 589 in the same file
gcc/attribs.c.
Now since I don't know whether simple_cst_equal really compares the value of
the attribute, or just some attribute type, it may be that the code does not do
what I hope to achieve.
Any comments how to improve the patch are very welcome.
Best,
Gert
