[New-bugs-announce] [issue43166] Unused letters in Windows-specific pragma optimize

[Guido van Rossum]

New submission from Guido van Rossum <guido at python.org>:

A coworker happened to look at our use of #pragma optimize() for Windows (VS 2017) and noticed:

unless there’s something I’m missing, the ‘a’ and ‘w’ portions of the string being passed to the optimize pragma are not doing anything; I’m pretty sure they’ve been useless for 10+ years. The ‘g’ means turn on global optimizations and the ‘t’ means optimize for “time” (i.e. speed). See the documentation at https://docs.microsoft.com/en-us/cpp/preprocessor/optimize?view=msvc-160
