Subject: Don't check for null after calling COFFObjectFile::toSec.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=63cdf9f8da4065608e16317d4c84d4768a4c508d

Don't check for null after calling COFFObjectFile::toSec.

It can only return null if passed a corrupted reference with a null Ref.p.
Checking for null is then an issue for asserts to check for internal
consistency, not control flow to check for invalid input.

I didn't add an assert(sec != nullptr) because toSec itself has a far more
complete assert.
