Subject: sim: replace custom attributes with ansidecl.h
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f0c4dc40b2e16a876b5b61986de5014a78f76a5c;p=binutils-gdb.git

sim: replace custom attributes with ansidecl.h

A lot of this code predates the common attributes.  We had already
started migrating over piece by piece, so just do a pass across all
the attributes and replace most of them.
