| Syntax: | Default: |
| /Om[+|-] | /Om- |
Use /Om to limit the working set size for the compiler.
The compiler may use a large amount of memory when inlining user code, especially when performing automatic inlining at large thresholds (/Oi50 and higher).
By default, there is no limit to the compiler's working set size.
Note: Because /Om[+] can cause the compiler to disregard some inlining opportunities, code generated with /Om- (the default) may be more efficient.
