Log Message
Merged r235177 - The DFG CFGSimplification phase shouldn’t jettison a block when it’s the target of both branch directions.
https://bugs.webkit.org/show_bug.cgi?id=188298
<rdar://problem/42888427>
Reviewed by Saam Barati.
JSTests:
* stress/bug-188298.js: Added.
Source/_javascript_Core:
In the event that both targets of a Branch is the same block, then even if we'll
always take one path of the branch, the other target is not unreachable because
it is the same target as the one in the taken path. Hence, it should not be
jettisoned.
* _javascript_Core.xcodeproj/project.pbxproj:
- Added DFGCFG.h which is in use and should have been added to the project.
* dfg/DFGCFGSimplificationPhase.cpp:
(JSC::DFG::CFGSimplificationPhase::run):
