Subject: [SystemZ] Do not install IfConverter pass at -O0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2c356f3a7a3fcbdb36dcf3d09e56557f905353a2;p=platform%2Fupstream%2Fllvm.git

[SystemZ] Do not install IfConverter pass at -O0

When not optimizing, do not run the IfConverter pass, this makes
debugging more difficult (and causes a testsuite failure in
DebugInfo/unconditional-branch.ll).
