Compiler Warning (level 1) C4952

  • Article

'function' : no profile data found in program database 'pgd_file'

When using /LTCG:PGUPDATE, the compiler detected an input module that was recompiled after /LTCG:PGINSTRUMENT and has a new function (function) present.

This warning is informational. To resolve this warning, run /LTCG:PGINSTRUMENT, redo all test runs, and run /LTCG:PGOPTIMIZE.

This warning would be replaced with an error if /LTCG:PGOPTIMIZE had been used.
