Function supportsUnwinding [src]

Tells whether unwinding for this target is supported by the Dwarf standard. See also std.debug.SelfInfo.supportsUnwinding which tells whether the Zig standard library has a working implementation of unwinding for this target.

Prototype

pub fn supportsUnwinding(target: std.Target) bool

Parameters

target: std.Target

Source

  pub fn supportsUnwinding(target: std.Target) bool {
    return switch (target.cpu.arch) {
        .amdgcn,
        .nvptx,
        .nvptx64,
        .spirv,
        .spirv32,
        .spirv64,
        => false,

        // Enabling this causes relocation errors such as:
        // error: invalid relocation type R_RISCV_SUB32 at offset 0x20
        .riscv64, .riscv32 => false,

        // Conservative guess. Feel free to update this logic with any targets
        // that are known to not support Dwarf unwinding.
        else => true,
    };
