New Revision: 374449<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=374449&view=rev" rel="noreferrer" target="_blank">http://llvm.org/viewvc/llvm-project?rev=374449&view=rev</a><br>
Log:<br>
Add -fgnuc-version= to control __GNUC__ and other GCC macros<br>
<br>
I noticed that compiling on Windows with -fno-ms-compatibility had the<br>
side effect of defining __GNUC__, along with __GNUG__, __GXX_RTTI__, and<br>
a number of other macros for GCC compatibility. This is undesirable and<br>
causes Chromium to do things like mix __attribute__ and __declspec,<br>
which doesn't work. We should have a positive language option to enable<br>
GCC compatibility features so that we can experiment with<br>
-fno-ms-compatibility on Windows. This change adds -fgnuc-version= to be<br>
that option.<br>
<br>
My issue aside, users have, for a long time, reported that __GNUC__<br>
doesn't match their expectations in one way or another. We have<br>
encouraged users to migrate code away from this macro, but new code<br>
continues to be written assuming a GCC-only environment. There's really<br>
nothing we can do to stop that. By adding this flag, we can allow them<br>
to choose their own adventure with __GNUC__.<br>
<br>
This overlaps a bit with the "GNUMode" language option from -std=gnu*.<br>
The gnu language mode tends to enable non-conforming behaviors that we'd<br>
rather not enable by default, but the we want to set things like<br>
__GXX_RTTI__ by default, so I've kept these separate.<br>
<br>
Helps address PR42817<br>
