Subject: [cmake] Add support for using the standalone leaks sanitizer with LLVM.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=864e349715f5e32049bef560a23777b465f6c8ca;p=llvm

[cmake] Add support for using the standalone leaks sanitizer with LLVM.

This commit causes LLVM_USE_SANITIZER to now accept the "Leaks" option. This
will cause cmake to pass in -fsanitize=leak in all of the appropriate places.

I am making this change so that I can setup a linux bot that only detects
leaks.
