functions. In the prior commit, we provide ordering to the LCG between functions and library function definitions that they might begin to call through transformations. But we still would delete these library functions from the call graph if they became dead during inlining. While this immediately crashed, it also exposed a loss of information. We shouldn't remove definitions of library functions that can still usefully participate in the LCG-powered CGSCC optimization process. If new call edges are formed, we want to have definitions to be called. We can still remove these functions if truly dead using global-dce, etc, but removing them during the CGSCC walk is premature. This fixes a crash in the new PM when optimizing some unusual libraries that end up with "internal" lib functions such as the code in the "R" language's libraries. llvm-svn: 308417 |
