Is there an alternative to the -Winline compiler option for Windows? I want to know which functions are inlined, which __forceinline functions are actually being inlined, etc.
Yes, you can find out which functions are lined using the ipo report.
for 9.1: /Qipo /Qopt-report /Qopt-report-phaseipo
for 10.0: /Qopt-report 1 /Qopt-report-phase:ipo
You can find those info in the User's Guide. Search for "inline report".
