Default Behavior of the Compiler
If you do not specify any options when you invoke the Intel®
C++ Compiler, the compiler uses the following default settings:
- Produces executable output with filename a.out.
- Invokes options specified in a configuration file
first. See Configuration Files.
- The location of shared objects is specified by the
LD_LIBRARY_PATH environment variable.
- Sets 8 bytes as the strictest alignment constraint
for structures.
- Displays error and warning messages.
- Performs standard optimizations using the default
-O2 option. See Setting
Optimization Levels.
- On operating systems that support characters in Unicode*
(multi-byte) format, the compiler will process file names containing these
characters.
If the compiler does not recognize a command-line option, that option
is ignored and a warning is displayed. See Diagnostic
Messages for detailed descriptions about system messages.
