Intel® Fortran Compiler 16.0 User and Reference Guide
Determines whether unwind information is precise at an instruction boundary or at a call boundary.
Linux and OS X: | -fasynchronous-unwind-tables -fno-asynchronous-unwind-tables |
Windows: | None |
None
Intel® 64 architecture: -fasynchronous-unwind-tables |
The unwind table generated is precise at an instruction boundary, enabling accurate unwinding at any instruction. |
IA-32 architecture: -fno-asynchronous-unwind-tables |
The unwind table generated is precise at call boundaries only. |
This option determines whether unwind information is precise at an instruction boundary or at a call boundary. The compiler generates an unwind table in DWARF2 or DWARF3 format, depending on which format is supported on your system.
If -fno-asynchronous-unwind-tables is specified, the unwind table is precise at call boundaries only. In this case, the compiler will avoid creating unwind tables for routines such as the following:
A C++ routine that does not declare objects with destructors and does not contain calls to routines that might throw an exception.
A C/C++ or Fortran routine compiled without -fexceptions, and on Intel® 64 architecture, without -traceback.
A C/C++ or Fortran routine compiled with -fexceptions that does not contain calls to routines that might throw an exception.
