Function supportsUnwinding [src]

Tells whether unwinding for this target is implemented here in the Zig standard library. See also Dwarf.abi.supportsUnwinding which tells whether Dwarf supports unwinding on that target in theory.

Prototype

pub fn supportsUnwinding(target: *const std.Target) bool

Parameters

target: *const std.Target
