New Revision: 191653<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=191653&view=rev" target="_blank">http://llvm.org/viewvc/llvm-project?rev=191653&view=rev</a><br>
Log:<br>
Add a bunch of other GCC '-f' options and ignore them. This covers every<br>
such option I've been able to find in the wild in our build system.<br>
<br>
Note that I haven't added test cases for this. I can do so if folks<br>
want, but they're *really* boring considering that this is all generated<br>
code to parse and ignore unsued options.<br></blockquote><div><br></div><div>I don't think these are quite right:</div><div><br></div><div>-ffunction-attribute-list, -finline-limit, -ftls-model, and -ftree-vectorizer-verbose need an "=argument" in GCC, and are rejected without. This patch seems to reject them with the argument but accept them without.</div>
<div><br></div><div>-fprofile-generate-sampling and -fprofile-reusedist are only accepted by the google branch of GCC, as far as I can see. Maybe that's fine, though -- I understand various groups use compilers built from that branch.</div>
<div><br></div><div>I can't find any GCC (neither trunk nor google branch) that accepts -fgnu nor -fprintf. Maybe these are typos in the relevant build rules?</div><div><br></div><div>-fspec-constr-count and -fregs-graph are GHC options, not GCC options.</div>
