<pre>On my x64 linux machine, I noticed that the compiler no longer seems to allow
creating a vector with >= 1024 elements after commit 6f28e09. Is this
intentional? Gcc allows it, and clang prior to this change did as well.
Here is the code I tried to build:
_attribute__((vector_size_(1024))) char foo;
And here is the compiler output:
dyung@rigel:~$ ~/src/upstream/6f428e09-linux/bin/clang -c -Wall test.cpp
test.cpp:1:16: error: vector size too large
__attribute__((__vector_size__(1024))) char foo;
^ ~~~~
1 error generated.</pre>
