fasynchronous-unwind-tables
Determines whether unwind information is precise at an instruction boundary or at a call boundary.
Syntax

-fasynchronous-unwind-tables -fno-asynchronous-unwind-tables |
macOS: |
-fasynchronous-unwind-tables -fno-asynchronous-unwind-tables |
Windows: |

Arguments
None
Default
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 (ifort only): -fno-asynchronous-unwind-tables |
The unwind table generated is precise at call boundaries only. |
Description
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.
