This topic lists the options that provide new functionality in this release.
Some compiler options are only available on certain systems, as indicated by these labels:
| Label | Meaning |
|---|---|
| i32 | The option is available on systems using IA-32 architecture. |
| i64em | The option is available on systems using IntelŪ 64 architecture. |
| i64 | The option is available on systems using IA-64 architecture. |
If no label appears, the option is available on all supported systems.
If "only" appears in the label, the option is only available on the identified system.
For more details on the options, refer to the Alphabetical Compiler Options section.
For information on conventions used in this table, see Notation Conventions.
New compiler options are listed in three tables below:
The first table lists new options that are available on Windows systems.
The second table lists new options that are available on Linux and Mac OS systems. If an option is only available on one of these operating systems, it is labeled.
