| // List of all flags in the VM. |
| // Flags can be one of three categories: |
| // * P roduct flags: Can be set in any of the deployment modes, including in |
| // production. |
| // * D ebug flags: Can only be set in debug VMs, which also have assertions |
| // enabled. |
| // * R elease flags: Generally available flags except when building product. |
| // * pre C ompile flags: Generally available flags except when building product |
| // or precompiled runtime. |
| // |
| // Usage: |
| // P(name, type, default_value, comment) |
| // D(name, type, default_value, comment) |
| // R(name, product_value, type, default_value, comment) |
